The hard disk fixing device 30 of the present invention is fixed on the main casing 32 of the notebook computer 3 , and the hard disk can be installed in the hard disk fixing device 30 . Wherein, the hard disk may be a head type hard disk or a solid state hard disk (Solid State Disk, SSD).

Please refer to FIG. 2A to FIG. 2C for the process of installing the hard disk fixing device 30 of the present invention into the hard disk 34 . First, as shown in FIG. 2A , the hard disk 34 is obliquely inserted into the hard disk fixing device 30 (as shown in the direction of the hollow arrow), so that the hard disk 34 can be inserted into the accommodation space formed by the upper casing 300 and the lower casing 302, and The hard disk 34 passes through the opening 3022 of the lower casing 302 .

Next, as shown in FIG. 2B , move the hard disk 34 a distance in the direction of the hollow arrow, so that the hard disk 34 is connected to the signal connector 362 (eg, SATA connector, PATA connector) and power connector 360 (eg, 4pin connector, 15pin connector). In this way, the hard disk 34 can transmit signals to and from the circuit board (not shown) through the signal connector 362 , and can obtain power from the circuit board through the power connector 360 . On the contrary, if the hard disk 34 is to be pulled out from the hard disk fixing device 30 , the hard disk 34 needs to be pushed forward for a certain distance to break away from the connection with the power connector 360 and the signal connector 362 .

Then, with the crossbar 3024 on one side of the opening 3022 (as shown in FIG. 2A ) as the axis of rotation, the upper casing 300 is rotated relative to the lower casing 302 and moved toward the lower casing 302, as shown in the arc in FIG. 2B indicated by the direction of the arrow. Then, the fixing component 304 installed on the upper case 300 can be engaged with the stop portion 3020 of the lower case 302 . The upper casing 300 can be tightly fastened with the lower casing 302 through the fixing component 304, as shown in FIG. 2C, to achieve the effect of fixing the hard disk 34

The engagement between the upper case 300 and the lower case 302 is accomplished by the fixing component 304 , which has enough fixing force for daily use. If the user does not need to frequently plug and unplug the hard disk for a period of time, after the step in FIG. 2B , the step in FIG. 2C can be followed to lock the locking members 306 (such as screws) into the locking holes 3000 of the upper housing 300 in sequence. And the locking hole (not shown) of the lower housing 302 to further strengthen the fixing force. Of course, if you want to take out the hard disk, you need to loosen the locking member 306 (for example, unscrew the screw), and then pull the fixing component 304 away from the lower casing 302 to release the locking effect.

In order to understand more clearly how the fixing component 304 of the present invention engages with the lower casing 302 , please refer to FIG. 2B and FIG. 3 . As shown in FIG. 2B , the fixing component 304 includes an annular elastic body 3044 , an engaging member 3042 and a grip portion 3040 . One side of the annular elastic body 3044 is fixed to the upper housing 300 , and the other side extends from the grip portion 3040 and the grip portion. Assembly 3042. FIG. 3 is a cross-sectional view illustrating that the engaging member 3042 in FIG. 2B is engaged with the lower case 302 .

As shown in FIGS. 2B to 3 , since the front edge portion of the lower housing 302 is surrounded by the main housing 32 , when the fixing component 304 mounted on the upper housing 300 moves toward the lower housing 302 , snap-fit The inclined portion 30422 of the member 3042 will contact the main casing 32 first. Then, since the inclined portion 30422 of the engaging member 3042 forms an acute angle with the moving direction, the inclined portion 30422 will not be blocked by the main housing 32, but will slide relative to the main housing 32 (at the same time, the annular elastic body 3044 is squeezed compression deformation), and then the inclined portion 30422 contacts and slides on the lower casing 302 . Therefore, the upper case can be smoothly moved toward the lower case. Finally, the engaging part 3042 can slide into the recessed space below the stopping part 3020 , that is, the flat part 30420 of the engaging part 3042 is located under the stopping part 3020 , and the engaging action is completed here. If the engaging part 3042 is going to move upward (that is, open the upper casing 300 ), the planar part 30420 will be in contact with the stop part 3020 (that is, the engaging part 3042 is blocked by the stop part 3020 ). Therefore, the upper case 300 cannot be separated from the lower case 302 to achieve the purpose of fixing the hard disk 34 .

In order to understand more clearly how the fixing assembly 304 of the present invention disengages from the lower housing 302 , please refer to FIGS. 4A-4B . FIG. 4A is a top view illustrating that the engaging member 3042 in FIG. 2B is engaged with the lower casing 302 . FIG. 4B is a top view illustrating that the engaging member 3042 in FIG. 4A is pulled away from the lower casing 302 . It should be noted that the lower housing 302 in FIG. 2B is covered by the main housing 32. For the convenience of illustration, the main housing 32 in FIG. 2B is removed from FIG. 4A and FIG. The top view of 4B directly looks at the lower housing 302 in FIG. 2B.

As shown in FIGS. 4A to 4B , if the engaging member 3042 is to be pulled away from the lower housing 302 , a force can be applied to the grip portion 3040 , and the direction of the force (as shown by the arrow) is toward the direction of the annular elastic body 3044 . central. Therefore, the movement of the holding portion 3040 will force the annular elastic body 3044 to deform, as shown in FIG. 4B , and also drive the engaging member 3042 away from the lower casing 302 . Furthermore, the movement of the engaging member 3042 will not be blocked by the lower case 302 , so the upper case 300 can be opened to achieve the purpose of taking out the hard disk (not shown in FIG. 4B ).

In addition, as shown in FIG. 4A , the elastic restoring force exerted by the annular elastic body 3044 on the engaging member 3042 is related to the length L1 of the elastic arms located on both sides of the engaging member 3042 . The longer the extension length L1, the smaller the elastic recovery force, but it is easier to pull the engaging member 3042 away from the lower housing 302; on the contrary, the shorter the extension length L1, the greater the elastic recovery force, but the engaging member 3042 It is also less easy to pull off the lower housing 302 . Furthermore, as shown in Figure 3, the higher the height H1 of the annular elastic body 3044, the stronger the rigidity, that is, when the engaging member 3042 and the stopper 3020 are pushed against each other, the annular elastic body 3044 is not easily deformed longitudinally, thereby strengthening the snap force. All in all, the design of the annular elastic body 3044 needs to consider the locking strength and the user's ease of use, so that the locking member 3042 can be firmly engaged with the stopper 3020 to stabilize the hard disk 34 without making it difficult for the user to pull the card. The fitting 3042 allows the user to easily open the upper casing 300 .

Generally speaking, springs are the most common element for providing elastic restoring force, but due to the weak rigidity of the springs, they cannot provide sufficient engaging force for the engaging part 3042 . Therefore, other fixing elements need to be matched in structural design, so that the engaging member 3402 can be stably engaged with the stop portion 3020 . However, the interior space of the notebook computer is limited, so the simpler the elements of the fixing assembly 304, the better. Therefore, in the limited space, the utility model adopts the design of the annular elastic body 3044, and at the same time takes into account the requirements of elastic force and fixing force, so that the hard disk fixing device 30 of the present utility model can easily load and remove the hard disk 34, and also Can stabilize the hard disk 34.

Compared with the prior art, the electronic device and its hard disk fixing device of the present utility model fix the upper case on the The lower casing achieves the function of stabilizing the hard disk. Moreover, since the annular elastic body can be deformed, the locking part extended from the annular elastic body can detachably engage the stop part, so the user only needs to pull the locking part away from the stop part to open the upper case body and then pull out the hard drive. In other words, the physical deformation of the annular elastic body and the engagement of the engaging parts can simply engage or disengage the upper case from the lower case, so the electronic device and its hard disk fixing device of the present invention can achieve fast and convenient The purpose of moving out and inserting into the hard disk.

Through the above detailed description of the preferred embodiments, it is hoped that the features and spirit of the present utility model can be described more clearly, and the scope of the present utility model is not limited by the preferred embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent scope of the utility model.
