Description

The invention relates to vehicles and can be used in the design of trolleys, wheelchairs, prams, for example, to move up stairs and overcome other specialized obstacles.

The relevance of the task. Most people with disabilities live in multi-storey buildings without elevators and ramps. Going out of the house is a big problem for them. Hundreds of thousands of people want a wheelchair that can move up the stairs.

A vehicle is known (patent RU 2102957, A61G 5/06) for moving along steps, which is equipped with a step-by-step working mechanism in the form of two pairs of support strips, which are fixed at one end to a crankshaft mounted on the frame and mounted at the other end with the possibility of return translational movement in the wings, also rigidly mounted on the frame, and in the slats are installed with the possibility of vertical movement spring-loaded rods-hooks.

The disadvantages of such a vehicle: the complexity of the device as a whole, containing a large number of auxiliary parts, hence the insufficient degree of reliability of the operation of walking mechanisms when moving along stairs.

The closest technical solution is a vehicle (patent SU 1581312, A61G 5/02), containing a frame, seat, driving and driven wheels, as well as a device for moving along flights of stairs, made in the form of radial, spring-loaded telescopic pins mounted on drive wheels with a retainer of the initial position and two attached to the frame and having the ability to move relative to the plane passing through the wheel support points, skid-shaped supports (skis).

The disadvantage of such a vehicle when moving along steps is the possibility of the pins jumping to the lower step if the tip of the pin hits the edge of the step, which disrupts the ride. The complex construction of the drive wheels: telescopic pins, radial guides, springs, clips. The inability to automatically switch from the mode of movement on a flat surface to a stepped surface, the need for time to prepare the drive wheels, i.e. extension of pins, their fixation.

The technical result of the claimed technical solution is to simplify and increase the reliability of the device, the ability to automatically without preparation to switch from the mode of movement on a flat surface to a stepped surface and vice versa, the smooth movement of the device.

The technical result is achieved by the fact that the vehicle contains a frame, wheels, and the supporting circular surface of the wheel is made wavy and / or zigzag, and / or the end side of the supporting circular surface of the wheel is provided with pins, the axle of the wheel is pivotally connected to a sleeve located inside the wheel hub, with the possibility of rotation and with the possibility of rotation of the longitudinal plane of the wheel relative to the axis of the wheel by a certain angle depending on the place of contact of the wheel bearing surface with the obstacle profile (roads).

The vehicle contains a frame 1 (Fig.1, 8-10, 17, 18, 22, 23, 25-27), wheels 2 (Fig.1-28). The supporting circular surface 3 of the wheel 2 is made wavy 4 (Fig.1-18), for example sinusoidal, and is made of pipe 5 (Fig.2-11) of an aluminum alloy, for example grade D16, and is connected to the hub 6 by knitting needles 7.

The supporting circular surface 3 (Fig.25, 26) of the wheel 2 is made wavy 4, for example sinusoidal, and is made of an aluminum alloy pipe 5, for example, grade D16, and is connected to the hub 6 by spokes 7 and has an additional supporting surface in the form of a rim 8.

The supporting circular surface 3 (Figs. 14-18) of the wheel is made wave-like 4, for example, sinusoidal, and is made of an integral aluminum alloy with wave-shaped disks 9 with a hub 6, for example, grade D16.

The supporting circular surface 3 (Fig.14-18) of the wheel 2 can be made zigzag 10, for example, "P" -shaped zigzags, and is made of a solid aluminum alloy with zigzag disks 11 with a hub 6, for example brand D16.

The supporting circular surface 3 (Fig.27-28) is equipped with pins 12 located on the end side 13 of the rim 8 and having a step equal to the step of the step.

The supporting circular surface 3 (Fig.1-28) of the wheel 2 is provided with protectors 14 of rubber material.

The axis 15 (Fig.1, 7-11, 17, 18, 22, 23, 25, 27) of the wheel 2 is pivotally connected 16 (Fig.7-9, 11) with a sleeve 17 located inside the hub 6 of the wheel 2 with rotation and with the possibility of rotation of the longitudinal vertical plane of the wheel 2 relative to the axis 15 of the wheel 2 by a certain angle depending on the point of contact 18 (Fig.7-9, 12, 13, 18) of the supporting surface 3 of the wheel 2 with the profile of the obstacle 19 (Fig.7) (roads). The hinge 16 (Fig.7-9, 11) is located inside the sleeve 17 in the form of an articulated hinge 16 with a longitudinal axis 20 (Fig.3-6, 12-14, 16, 19, 21, 24) with washers 21 passing through the middle the longitudinal axis of the wheel 2. Wheel 2 (Fig.1-28) consists of a hub 6, a bearing 22 (Fig.5-9) installed in the hub 6 of the outer race 23 of the bearing 22, the sleeve 17 installed in the inner race 24 of the bearing 22, side flanges with a large diameter of 25 and a small diameter of 26. Each wheel 2 can be equipped with an electric motor (not shown) located directly in the hub 6.

The operation of the device.

The movement of the vehicle on a flat horizontal plane. The longitudinal plane of the wheel 2 (11) relative to the axis 15 of the wheel 2 is 90 ° due to the fact that the gravity 27 of the vehicle falls on the longitudinal axis 20 of the hinge 16, passing through the middle longitudinal axis of the wheel 2, and is directed vertically.

Vehicle movement on a flat inclined plane. The longitudinal plane of the wheel 2 (Fig.7) relative to the axis 15 of the wheel 2 is a certain angle due to the fact that the gravity 27 of the vehicle falls on the longitudinal axis 20 of the hinge 16, passing through the middle longitudinal axis of the wheel 2, and is directed vertically, which allows automatically change the plane of the wheel 2.

The movement of the vehicle on rough roads. The longitudinal plane of the wheel 2 (Fig.7, 18) relative to the axis 15 of the wheel 2 changes the angle due to the fact that the gravity 27 (Fig.7) of the vehicle falls on the longitudinal axis 20 of the hinge 16 passing through the middle longitudinal axis of the wheel 2, and directed vertically. Around the longitudinal axis 20, passing through the middle longitudinal axis of the wheel 2, the wheel 2 tilts when driving on rough roads, which allows you to automatically change the plane of the wheel 2.

The movement of the vehicle along the steps 28 (Figs. 8, 9, 12, 13) of the ladder 29. The longitudinal plane of the wheel 2 relative to the axis 15 of the wheel 2 changes the angle due to the fact that the gravity 27 of the vehicle falls on the longitudinal axis 20 of the hinge 16 passing through the middle longitudinal axis of the wheel 2, and is directed vertically, which allows you to automatically change the longitudinal plane of the wheel 2. Moreover, each wheel 2 is supported at least at two points 18.

Depending on the step of the wave-like 4 (Fig. 8, 9, 12, 13) and / or zigzag 10 of the supporting circular surface 3 of the wheel 2, the angle of inclination of the wheel 2 may not change during movement along the stairs 29, if the step of the wave-shaped bearing surface 4 of the wheel is step 28, the depression 30 of the undulating and / or zigzag profile of the supporting surface 3 has a contact 18 with the top of the step 31, and the top 32 of the undulating and / or zigzag profile of the supporting surface with an inner angle 33 of the step.

If the step of the wave-like 4 supporting circular surface 3 of the wheel 2 is two times greater than the step of the step 28, then the longitudinal plane of the wheel 2 relative to the axis 15 of the wheel 2 changes the angle during movement along the steps 28, shifting from side to side. At the same time, during the descent, participation in the process of a person sitting in a vehicle is practically not required - if necessary, a person only slows down the vehicle. Due to the undulating profile 4 of the supporting surface 3, the vehicle moves steadily along the steps, having contact at least at two points 18. To lift the vehicle with an electric drive, for example an electric motor (not shown) located directly in the hub 6, the lifting process provides a large vehicle mobility. The supporting circular surface 3 (Figs. 27, 28) is provided with pins 12 located on the end face 13 and having a step equal to the step of the step 28. In this case, the end side 13 of the supporting circular surface 3 has a contact 18 with the top of the step 31, and the pin 12 has contact 18 with an internal angle 33 of the step 28.

Off-road vehicle movement. The longitudinal plane of the wheel 2 (Fig.7) relative to the axis 15 of the wheel 2 changes the angle due to the fact that the gravity 27 of the vehicle falls on the longitudinal axis 20 of the hinge 16, passing through the middle longitudinal axis of the wheel 2, and is directed vertically. Around the longitudinal axis 20, passing through the middle longitudinal axis of the wheel 2, the wheel 2 tilts when driving off-road, which allows you to automatically change the longitudinal plane of the wheel 2. The supporting circular surface 3 of the wheel 2, made in a wavy and / or zigzag shape, performs the function of the lug 34.

In contrast to the prototype in the proposed technical solution, the supporting circular surface 3 (Fig.1-18) of the wheel 2 is made wavy 4 and / or zigzag 10 (Fig.14-18), which excludes special devices for moving along steps 28 (Fig.8 , 9, 12, 13) - simplifies the design of the vehicle.

In contrast to the prototype in the proposed technical solution, each wheel 2 is supported at least at two points 18 (Figs. 7-9, 12, 13, 18), which increases reliability when moving along the steps 28 of the vehicle. Unlike the prototype, in the proposed technical solution, the longitudinal plane of the wheel 2 automatically changes: the gravity force 27 (Fig. 7-10) of the vehicle falls on the longitudinal axis 20 of the hinge 16 passing through the middle longitudinal axis of the wheel 2, and is directed vertically, which makes it possible automatically without preparation, switch from the mode of movement on a flat surface to a stepped surface and vice versa.

Unlike the prototype, in the proposed technical solution, the depression 30 (FIGS. 8, 9, 12, 13) of the wave-shaped 4 and / or zigzag profile 10 of the supporting surface 3 has a contact 18 with the top of the step 31, and the peak 32 of the wave-shaped 4 and / or zigzag 10 the profile of the supporting surface with an internal angle 33 of the step 28, which allows the vehicle to smoothly move along the steps 28.

The claimed technical solution has differences from the closest analogues, respectively, the claimed solution satisfies the condition of patentability of the invention of "novelty."

The technical solution does not explicitly follow from the prior art. In addition, in the process of patent search did not reveal technical solutions having features that match the distinctive features of the claimed technical solution. The claimed invention is technically feasible, industrially feasible at an engineering enterprise.

In this regard, the invention corresponds to the level of patentability and is industrially applicable.
