Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to FIG. 1 , it shows a structural schematic view of an embodiment of a device for installing a vehicle-mounted hard disk according to the present invention. As shown in the figure, it includes a shell 1 , an outer bottom plate 3 , an “L”-shaped bracket 2 , and a rubber shock-absorbing pad 5 .

Wherein, the outer bottom plate 3 is located at the bottom of the housing 1 , and is fixed to the bottom of the housing 1 through the “L”-shaped bracket 2 . Specifically, the "L"-shaped bracket is arranged on both sides of the housing 1, its upper end is fixed on the side plates on both sides of the housing 1, and its lower end is passed through the rubber shock-absorbing pad 5 and the screw. 4 is fixed on the outer bottom plate 3.

Referring to FIG. 5 and relevant parts in FIG. 3 at the same time, the rubber shock absorbing pad 5 is dumbbell-shaped. It includes an upper shock-absorbing pad 51 and a lower shock-absorbing pad 52, and a neck 53 between the upper shock-absorbing pad 51 and the lower shock-absorbing pad 52; The shock pad 5 also includes a shaft hole 54 passing through the upper and lower shock pad plates 51 , 52 and the neck 53 to accommodate the fixing screw 4 .

The "L" shaped bracket 2 includes an upper handle 21 and a lower handle 22 . The upper handle 21 is fixedly connected to the side plates on both sides of the housing 1 , and the lower handle 22 is fixedly connected to the outer bottom plate 3 .

Wherein, the lower handle 22 includes a neck hole 221 , which is an unclosed opening located on the lower handle 22 and used to accommodate the neck 53 .

In this way, during installation, the neck portion 53 snaps into the neck hole 21 , and the screw 4 passes through the shaft hole 54 and is fixed on the screw column 31 of the outer bottom plate 3 . The upper and lower shock-absorbing pads 51 , 52 are located on the upper and lower sides of the lower handle 22 . The lower shock-absorbing pad 52 is located between the lower handle 22 and the outer floor 3. Since the lower shock-absorbing pad 52 has a certain thickness, it makes the installation device of the entire vehicle-mounted hard disk suspended in the air. For the outer bottom plate 3 , the lower shock-absorbing pad 52 can effectively attenuate the vibration transmitted from the outer bottom plate 3 .

For the vibration transmitted through the screw 4 , the upper shock-absorbing pad 51 can also effectively dampen the vibration; and the neck 53 can also effectively dampen the vibration.

And, because the surface of the neck 53 is gear-shaped, it can increase the frictional force, so that it is not easy to break away from the neck hole 221; , so it can also make the fixing of the screw 4 more firm, and it is not easy to loosen and come off.

The casing 1 includes a front panel 11 on which a door body 112 is arranged, and the door body 112 can be selectively opened and closed by a locking mechanism 111 arranged on the front panel 11 .

The open state of the door body 112 can refer to 2 , including the fence 7 and the push-pull handle 102 . Wherein, the fence 7 is provided with a quick-lock screw 71 and a hole 73, and the quick-lock screw 71 cooperates with the corresponding quick-lock mechanism to realize the opening and closing of the fence 7 (described in detail below), and the hole 73 is used to make the push-pull handle 102 protrude out of the fence 7 .

For the parts already explained in FIG. 1 , the same parts in FIG. 2 will not be described repeatedly.

Referring to FIG. 3 , it illustrates a schematic structural diagram of the embodiment shown in FIG. 1 in a disassembled state. As shown in the figure, it includes a top plate 12, a steel wire damping mechanism 8, a connecting column 9, a supporting plate 10, a fence 7, an upper guide rail 61, a lower guide rail 62, a coaming plate 13, a front panel 11, an outer bottom plate 3, screws 4, Rubber pad 5, "L" shaped bracket 2.

Wherein, the surrounding board 13 includes a side board, a rear board and a bottom board. The enclosure plate 13 together with the top plate 12 and the front panel 11 constitutes the internal accommodation space of the installation device of the vehicle hard disk.

The supporting plate 10 is hung and fixed on the top plate 12 through the connecting column 9, and it has no contact with the bottom plate of the housing 1, so that it can play a better vibration buffering effect. One side of the steel wire damping mechanism 8 is fixed on the supporting plate 10, and the other side is fixed on the lower guide rail 62; the lower guide rail 62 is flat, and the upper guide rail 61 is U-shaped, so that the upper guide rail 61 Fixing on the rear side of the lower guide rail 62 forms an accommodating space for accommodating the hard disk.

The existence of the fence 7 is to prevent the hard disk placed in the accommodating space formed by the two guide rails from sliding out. One section of it is rotatably connected to the upper guide rail 61, and the other end is provided with a quick lock screw 71, and a quick lock mechanism 72 (for example, fixed on the upper guide rail 61) is correspondingly provided on the closed position of the fence 7, so that through the The cooperation of the quick lock mechanism 72 and the quick lock screw 71 realizes the optional opening and closing of the fence 7 .

The fence 7 is also provided with a hole 73, the function of which has been described above and will not be repeated here.

Foam 612 is provided on the top of the upper guide rail 61 to attenuate vibration. Foam 101 is also provided on the supporting board 10 to attenuate vibration.

The top angle 611 of the upper guide rail 61 is set as a hypotenuse, and the hypotenuse cooperates with the hypotenuse 101 of the hard disk enclosure 100 in FIG. 4 to achieve the effect of anti-insertion prevention.

In FIG. 4 , a hard disk is accommodated in the hard disk box 100 , and a push-pull handle 102 is provided on the outside thereof in a push-pull direction.

The front panel 11 is further provided with an opening 113 , and the opening position of the opening 113 corresponds to the fence 7 , so that after installation, the fence 7 can be opened and closed through the opening 113 . The closing of the opening 113 is realized through the selective opening and closing of the door body 112 .

Since the structure and connection of the bottom plate 3, the "L"-shaped bracket 2, the screw 4, and the rubber pad 5 are described above, they will not be repeated.

In the present invention, the hard disk box 100 is taken as a removed whole, which contains a hard disk inside. Since the removed part only includes the hard disk box and the hard disk therein, it is small in size and light in weight, very easy to carry, and also beneficial to data transfer.

The upper guide rail and the lower guide rail are used as the hard disk bearing mechanism, and the steel wire damping mechanism is suspended on the top plate 12 together with the supporting plate as a damping mechanism, so that better damping effect can be achieved.

And the organic combination of three kinds of shock-absorbing modes of the foam, the steel wire shock-absorbing mechanism and the external rubber pad, which play a shock-absorbing effect inside, greatly enhances the shock-absorbing effect.

The use of the quick-lock screw and the quick-lock mechanism can quickly realize the opening and closing of the fence, which saves time. The existence of the door body can effectively prevent the hard disk from being stolen.

It can also be seen from the drawings that the slot for the memory card is arranged on the front panel, thus making it easier to pull out the memory card.

It can be seen from Fig. 3 and Fig. 5 that the neck of the rubber shock-absorbing pad is gear-shaped, which can reduce its resonant frequency, widen the shock-absorbing frequency range and achieve better shock-absorbing effect.

Due to the comprehensive application of foam damping, steel wire damping and rubber damping, when the whole device is in the resonance zone, the foam particularly plays a buffering role, the damping is large, and the energy of vibration is absorbed; and the steel wire damping device , when the vibration is low-frequency and high-amplitude, the buffering and shock-absorbing effect is particularly exerted, and the vibration is attenuated; and the rubber shock-absorbing method is especially for the buffering and shock-absorbing effect when the high-frequency and low-amplitude vibration is.

Therefore, the organic combination of the above three damping methods covers the vibration frequency range of the entire device. At low frequencies, the steel wire damping device plays a greater role, and at high frequencies, the rubber damping mode plays a greater role. greater effect, while in the resonance region, the foam plays a greater buffering role. Played a very good shock absorption effect.

It should be noted that the function of the upper and lower guide rails is to limit the movement of the hard disk and provide a sliding track. Therefore, it is not limited to the above-mentioned situation where the upper guide rail is U-shaped and the lower guide rail is flat plate, and the shapes can be replaced with each other, or any other structure that can achieve the purpose can be adopted.

The above disclosure is only a preferred embodiment of the present invention, which certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
