According to an embodiment of the present invention, referring to fig. 1 to 9, a fixing device, a tire pressure monitor and a monitoring method are provided. The securing device is adapted to secure a tire pressure monitor and may specifically include a strap 100 having a first end and a second end and a buckle 200 disposed at the first end of the strap 100. The buckle 200 is provided with an accommodating space 210 for the second end of the binding belt 100 to pass through, and a clamping block 211 is arranged in the accommodating space 210. The second end of the strap 100 is provided with a plurality of adjusting holes 110, and the adjusting holes 110 can be selectively and limitedly matched with the clamping blocks 211 so as to adjust the length of the second end of the strap 100 passing through the accommodating space 210. A stopper 212 is provided in the accommodating space 210 to be operable in a first position and a second position. In the first position, the limiting member 212 is separated from the clamping block 211; in the second position, the limiting member 212 abuts against the clamping block 211 to limit the second end of the strap 100 from being separated from the accommodating space 210.

Specifically, when the tire pressure monitor is fastened to the hub 400 by the fastening device, the user moves the stopper 212 to the first position, so that the stopper 212 and the clamping block 211 are in a separated state. Then, the second end of the strap 100 is passed through the receiving space 210 of the buckle 200, and the size of the area formed by the strap 100 is adjusted by changing the length of the second end of the strap 100 passing through the receiving space 210, so that the fixing device can be adapted to the hubs 400 of different sizes. After the tire pressure monitor is adjusted to a proper position, the clamping blocks 211 are in limit fit with the corresponding adjusting holes 110, and the limiting piece 212 is moved to the second position, so that the tire pressure monitor can be stably fixed on the hub 400 through the binding belt 100.

In contrast, if the tightness of the strap 100 needs to be adjusted, the limiter 212 can be moved from the second position to the first position, then the second end of the strap 100 is retracted, the tightness of the strap 100 can be changed, the strap 100 is adjusted to a proper tightness, and then the limiter 212 is moved back to the second position to complete the adjustment.

In this embodiment, the second end of the strap 100 is restricted from being separated from the accommodating space 210 by the positioning member 212, so that the loosening time of the strap 100 caused by the rotation of the tire can be effectively prolonged, the possibility of damage to the tire and the tire pressure monitor caused by the loosening of the strap 100 can be reduced, and the practicability is high. In addition, the fixing device provided by the embodiment can be better suitable for hubs 400 with different sizes, has a wide application range, and is beneficial to mass production and use.

It is worth noting that, when the fixing device is in tightness adjustment and disassembly, the disassembly and assembly of parts are not involved, and only the limiting piece 212 is required to be moved, so that the operation is convenient and quick, the situation that the parts are lost is avoided, and the use performances of the fixing device and the tire pressure monitor are guaranteed. Meanwhile, the user does not need to be provided with parts to be replaced, and the maintenance cost is low.

Specifically, referring to fig. 4 and 5, the clamping block 211 is inclined toward a direction away from the first end of the strap 100, and a clamping groove 2111 for placing the limiting member 212 is provided on a side of the clamping block 211 away from the strap 100. When the limiting piece 212 is at the first position, the limiting piece 212 is separated from the clamping groove 2111; when the limiting member 212 is at the second position, the limiting member 212 is clamped in the clamping groove 2111.

In this embodiment, the latch 211 is preferably elastic and has opposite ends. One end is a fixed end and is fixed in the accommodating space 210, and the other end is a movable end, and is suitable for acting on the adjusting hole 110. Thus, when the limiting member 212 is clamped in the clamping groove 2111, the limiting member 212 compresses the clamping block 211, so that the clamping block 211 is in limiting fit with any adjusting hole 110. In contrast, if the clamping block 211 has a tendency to separate from the corresponding adjusting hole 110 due to vibration, the limiting member 212 can also be pressed against the clamping block 211, so as to prevent the clamping block 211 from separating from the adjusting hole 110, and thus the binding band 100 is loosened.

In contrast, in the present embodiment, if the binding band 100 has a loosening tendency, then the end of the clamping block 211 that is in limit fit with the adjusting hole 110 will abut against the wall of the adjusting hole 110 to prevent the binding band 100 from loosening, which greatly improves the fixing effect of the fixing device on the tire pressure monitor, effectively prolongs the loosening time of the binding band 100 due to the rotation of the tire, and reduces the damage probability of the rubber tire and the tire pressure monitor due to the loosening of the binding band 100.

If the strap 100 tends to tighten, the adjustment aperture 110, which is in positive engagement with the latch 211, tends to move toward the second end. At this time, the hole wall of the adjusting hole 110 will apply pressure to the movable end of the clamping block 211, so that the clamping block 211 is separated from the adjusting hole 110 and cooperates with the adjacent adjusting hole 110 to tighten the binding band 100.

In this way, the user may not move the limiting member 212 from the second position to the first position during tightening of the strap 100, but directly pull the second end of the strap 100 to perform the adjustment.

Specifically, referring to fig. 4-6, the limiter 212 is a rod and is disposed along the width of the strap 100. At this time, abutment tables 2121 are disposed at two ends of the limiting member 212 and adapted to abut against the outer sidewall of the buckle 200, so as to limit the limiting member 212 from moving along the width direction of the strap 100. In contrast, the buckle 200 is provided with a first escape aperture 220 for escaping the limiting member 212.

Preferably, the first avoiding hole 220 is provided with a clamping position corresponding to the clamping groove 2111, so that the limiting member 212 is prevented from being separated from the clamping groove 2111 due to vibration when being positioned at the second position, and the limiting effect of the limiting member 212 is improved, so that the tire pressure monitor can be more stably fixed on the hub 400 through the fixing device.

In the above embodiments, referring to fig. 1 and 3 to 6, the second end of the strap 100 is preferably located on the side of the rest of the strap 100 away from the hub 400 when passing through the accommodating space 210, so as to be convenient for the user to adjust and further fit to the surface of the hub 400.

Specifically, referring to fig. 4 to 6, the buckle 200 is disposed at a side facing away from the strap 100, and a second avoidance hole 230 is disposed at a corresponding clamping block 211. In one aspect, the second escape hole 230 provides a deformation space for the latch 211. On the other hand, the finger of the user can directly press the clamping block 211 through the second avoiding hole 230, so that the movable end of the clamping block 211 is clamped in the appropriate adjusting hole 110, and then the limiting piece 212 is moved to the clamping groove 2111, so as to complete the fixation of the tire pressure monitor.

Referring to fig. 2, 3, 7 and 8, the present invention further provides a tire pressure monitor, which is suitable for monitoring the tire pressure of tires of small, medium and heavy commercial vehicles and engineering vehicles, and specifically may include a detection assembly 300, a screen display assembly and a fixing device provided by any of the foregoing embodiments. The fixing device is used for binding the detecting component 300 to the hub 400, the detecting component 300 is used for detecting the tire pressure and the binding pressure of the fixing device, and transmitting data to the screen display component, and the screen display component is used for displaying the data detected by the detecting component 300, so that the detecting component is more beneficial to the user to check and maintain the automobile and various parameters thereof.

Preferably, the detecting assembly 300 can detect the tire temperature in addition to the tire pressure and the binding pressure of the fixing device, thereby helping the user to further understand the real-time condition of the tire.

Specifically, referring to fig. 3, 7 and 8, the detection assembly 300 includes a body 310 and a holder 320. The body 310 is provided with a pressure sensor 311 adapted to be attached to the hub 400 for detecting the tire pressure and the binding pressure of the fixing device. The fixing base 320 is provided with a through hole 321 for the strap 100 to pass through, so as to fix the body 310 to the strap 100, and the fixing base 320 is provided with a third avoiding hole 322 corresponding to the pressure sensor 311. It should be noted that the stress sensor and the corresponding third avoiding hole 322 should be disposed away from the strap 100.

The fixing base 320 is preferably made of a spring steel material, has good elasticity, and also has good supporting strength, so that the overall strength of the detection assembly 300 is improved.

In this embodiment, the fixing base 320 and the body 310 are fastened and fixed by a fastener. Specifically, the fixing base 320 extends toward the body 310 to form a mounting ear, and the mounting ear and the body 310 are both provided with fastening holes. The fastening members sequentially pass through the fastening holes formed on the mounting lugs and the body 310 to fix the fixing base 320 and the body 310 together.

In practical production, the fastening members may be rivets, screws, bolts, etc., which are not described in detail herein, and are all within the scope of the present invention.

Preferably, referring to fig. 3, 7 and 8, at least one elastic piece 323 is disposed on a side of the fixing base 320, which is suitable for being attached to the hub 400, and the elastic piece 323 is disposed obliquely toward a direction away from the body 310. At this time, a fourth avoiding hole 324 is formed at the position of the fixing base 320 corresponding to the elastic sheet 323.

In this embodiment, when the tire pressure monitor is bound to the hub 400 by the fixing device, the spring plate 323 of the fixing base 320 and the pressure sensor 311 on the body 310 are preferentially contacted with the hub 400. The body 310 can determine whether the binding of the band 100 is tightly installed based on the data collected by the pressure sensor 311. When the binding band 100 is tightly bound, the hub 400 can exert force on the elastic sheet 323, so that the friction force between the fixing seat 320 and the hub 400 is increased, the loosening of the binding band 100 caused by vibration when the hub 400 rotates is reduced, and the loosening time of the binding band 100 is effectively prolonged. Meanwhile, the friction force between the fixing seat 320 and the hub 400 is increased, the detection assembly 300 can be prevented from moving on the surface of the hub 400, so that the tire pressure of the tire pressure monitor and the binding pressure of the fixing device can be detected more accurately, and the service performance is greatly improved.

In this embodiment, the vertical distance between the end of the spring plate 323 inclined towards the direction away from the body 310 and the fixing seat 320 should be no greater than 3mm.

Further, referring to fig. 3, 7 and 8, the fixing base 320 is provided with a baffle 325 for limiting the fixing base 320 from moving along the width direction of the binding band 100, so as to further improve the detection precision of the tire pressure monitor and improve the usability. Meanwhile, the provision of the barrier 325 also prevents the binding of the strap 100 from loosening due to the skewed passing.

In this embodiment, the fixing base 320 is preferably in a plate-shaped structure, and at this time, the baffle 325 can limit the position of the strap 100, and can also play a role of supporting the body 310, and space the body 310 from the spring plate 323 by a certain distance, so as to form a movable space for the spring plate 323 to deform.

In one embodiment, the body 310 may also be provided with a temperature sensor for detecting the temperature of the tire, which helps the user to more fully understand the real-time condition of the tire, thereby better checking and maintaining the vehicle and its various parameters.

Referring to fig. 9, the present invention further provides a monitoring method of a tire pressure monitor, which is used for the tire pressure monitor provided in any of the above embodiments, and specifically includes the following steps:

binding the tire pressure monitor to the hub 400 to monitor binding pressure, and if the magnitude of the monitored binding pressure is smaller than or equal to an initial binding pressure threshold, sending a prompt tone by the tire pressure monitor;

Preferably, the user can also preset a binding pressure prompt threshold, so that in the running process of the vehicle, if the detected binding pressure is greater than the binding pressure alarm threshold and is smaller than or equal to the binding pressure prompt threshold, the tire pressure monitor sends out prompt sound.

Further, the user may also preset a tie-up pressure too high threshold, and when the user ties up the tire pressure monitor to the hub 400, the tire pressure monitor sounds an alarm if the detected tie-up pressure is greater than the tie-up pressure too high threshold.

Specifically, referring to fig. 9, the initial binding pressure threshold range preset by the user may be 95-105N, the over-binding pressure threshold is 120N, the binding pressure prompt threshold is 80N, and the binding pressure alarm threshold is 60N.

When the user ties the tire pressure monitor to the wheel hub 400, if the detected tie pressure is in the range of 95-105N, the locking torque at this time is 10n·m, indicating that the tire pressure sensor is firmly installed. If the detected binding pressure is lower than 95N, the tire pressure monitor may give a warning sound, and the user should re-bind the binding band 100 after hearing the warning sound.

When the binding pressure after locking exceeds 120N, namely exceeds the threshold value of the too high binding pressure, the tire pressure monitor gives a warning prompt, and after hearing the prompt, the user should loosen the binding belt 100 to prevent the binding belt 100 from breaking due to the too large stress.

During the running process of the automobile, the binding band 100 is loosened to a certain extent, at this time, the binding pressure detected by the pressure sensor 311 is reduced, and when the binding pressure is reduced to 80N, the tire pressure monitor sends out a prompt tone to prompt the user that the binding band 100 is loosened. When the tying pressure drops to 60N, the tire pressure monitor sounds an alarm, prompting the user that the tie 100 has been loosened, and that the tie 100 should be re-tied.

In the foregoing embodiments, the descriptions of the embodiments are focused on, and the parts of a certain embodiment that are not described or depicted in detail may be referred to in the related descriptions of other embodiments.

It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
