[0043] Embodiment 1:

[0044] This embodiment provides a video recorder, including a hard disk bracket, a hard disk 100 and a lens. The hard disk 100 is installed on the hard disk bracket, and the hard disk 100 is electrically connected to the lens.

[0045] See also Figure 1 , Figure 3 and Figure 4 The hard disk bracket includes a base 1 and a pressure cover 2.

[0046] The base 1 is provided with a hard disk slot 11, and the shape of the hard disk slot 11 is generally a rectangular parallelepiped to adapt to the shape of the hard disk 100, thereby allowing the hard disk 100 to be accommodated in the hard disk slot 11. Among them, the side wall of the hard disk slot 11 is provided with a positioning protrusion 111, and the side wall of the hard disk 100 is provided with a positioning hole. When the hard disk 100 enters the hard disk slot 11, the positioning protrusion 111 can avoid the side wall of the hard disk 100 by deformation. After the hard disk 100 moves into place in the hard disk slot 11, the positioning protrusion 111 can be snapped into the positioning hole to position the hard disk 100 in the hard disk slot 11. Due to the small size of the positioning protrusion 111, the positioning protrusion 111 can only provide weak positioning or auxiliary positioning for the hard disk 100.

[0047] The pressure cover 2 is installed at the hard disk slot 11, and the pressure cover 2 can move along the depth direction of the hard disk slot 11. Figure 7-Figure 9 In this embodiment, the depth direction of the hard disk slot 11 is the first direction, and the first direction is perpendicular to the bottom wall of the hard disk slot 11. Figure 5 and Figure 7The cover 2 can avoid the hard disk 100 by moving in the first direction to ensure that the hard disk 100 can enter the hard disk slot 11 normally. After the hard disk 100 is positioned by the positioning protrusions 111, the cover 2 can move downward in the first direction to press the hard disk 100 on the bottom wall of the hard disk slot 11, thereby supplementing the positioning effect of the hard disk 100 and improving the stability of the hard disk 100 in the hard disk slot 11. Figure 8 and Fig. 9 The hard disk 100 has different thicknesses, Figure 8 The hard disk 100 is thicker, so the downward movement distance of the pressure cover 2 is smaller. Fig. 9 The thickness of the hard disk 100 is relatively thin, so the downward movement distance of the pressure cover 2 is relatively large. It can be seen that the positioning method of the pressure cover 2 on the hard disk 100 in this embodiment can be applied to hard disks 100 of different thicknesses, and has high applicability.

[0048] See also Figure 4 In this embodiment, the hard disk bracket further includes a first movable member 3 and a first elastic member 4. The first movable member 3 is provided with a second rack 31, and the side wall of the pressure cover 2 is provided with a first rack 21. Figure 2-Figure 9 The base 1 is also provided with a guide groove 12, which is connected to the hard disk slot 11. In this embodiment, the first movable member 3 is an L-shaped bent plate, and the edge and bottom surface of the first movable member 3 are both fitted in the guide groove 12, so that the first movable member 3 is slidably arranged in the guide groove 12 along the second direction. In this embodiment, the first rack 21 and the second rack 31 both extend along the first direction, and the first elastic member 4 is arranged along the second direction, the first direction is perpendicular to the second direction, and the two ends of the first elastic member 4 are respectively abutted against the first movable member 3 and the base 1.

[0049] The pressure cover 2 thus has a locked state and an unlocked state. Figure 6 and Figure 7 At this time, the cover 2 is in the unlocked state, and the first movable member 3 squeezes the first elastic member 4 so that the first rack 21 and the second rack 31 are spaced apart, so that the cover 2 can move along the first direction without being restricted by the first movable member 3. After the hard disk 100 completely enters the hard disk slot 11, the cover 2 can automatically fall down under the action of gravity and press on the hard disk 100. Figure 8 and Fig. 9 At this time, the pressure cover 2 is in a locked state. After the pressure cover 2 is pressed on the hard disk 100, the first movable member 3 moves toward the pressure cover 2 under the resetting action of the first elastic member 4 until the first rack 21 engages with the second rack 31. On the one hand, under the elastic force of the first elastic member 4, the first movable member 3 can press the pressure cover 2 on the side wall of the hard disk slot 11 along the second direction. On the other hand, the second rack 31 can limit the movement of the first rack 21 in the first direction, avoiding the separation of the pressure cover 2 and the hard disk 100, thereby ensuring the positioning effect of the pressure cover 2 on the hard disk 100.

[0050] Preferably, see Figure 7 In this embodiment, a guide tube 112 is provided on the bottom wall of the hard disk slot 11, and a guide rod 22 is provided on the pressure cover 2. The guide rod 22 is plugged into the guide tube 112 to guide the movement of the pressure cover 2 at the hard disk slot 11.

[0051] Embodiment 2:

[0052] The difference between this embodiment and embodiment 1 is that the hard disk bracket further includes an upper cover 5. Fig.10 , a positioning rib 51 is provided on the upper cover 5. Fig.11 When the cover 2 is in the locked state, the upper cover 5 covers the hard disk slot 11, and the positioning rib 51 abuts against the first movable member 3 along the second direction, so that the first movable member 3 further presses the cover 2 along the second direction, thereby increasing the pressure of the cover 2 on the side wall of the hard disk slot 11. The auxiliary limiting of the positioning rib 51 can effectively prevent the first rack 21 and the second rack 31 from being separated due to shaking or vibration, thereby improving the stability of the cover 2.

[0053] Embodiment 3:

[0054] See also Fig.12 The present embodiment provides a hard disk bracket, comprising a base 1, a pressure cover 2, a first gear 6, a lever 7 and a second elastic member 8. A hard disk slot 11 is provided on the base 1, the pressure cover 2 is installed at the hard disk slot 11, and the pressure cover 2 can move along the depth direction of the hard disk slot 11.

[0055] A first rack 21 is arranged on the side wall of the pressure cover 2, and the first gear 6 and the shifting rod 7 are both rotatably arranged on the base 1. Two ends of the second elastic member 8 are arranged on the shifting rod 7 and the base 1 respectively.

[0056] The pressure cover 2 in this embodiment also has a locked state and an unlocked state.

[0057] See also Fig.13 At this time, the pressure cover 2 is in an unlocked state, and the first gear 6 and the first rack 21 are spaced apart, so the movement of the pressure cover 2 in the first direction will not be restricted by the first gear 6. In some other embodiments, when the pressure cover 2 is in an unlocked state, the lever 7 is spaced apart from the first gear 6, so the lever 7 will not restrict the rotation of the first gear 6, and accordingly, regardless of whether the first gear 6 and the first rack 21 are in a meshing state, the pressure cover 2 can move in the first direction.

[0058] See also Fig.14 and 15At this time, the cover 2 is in a locked state, the first gear 6 and the first rack 21 are not only in a meshing state, but the end of the lever 7 also abuts against the first gear 6. At this time, if the cover 2 is to move up in the first direction, the first gear 6 will generate a counterclockwise torque, thereby causing the lever 7 to generate a clockwise torque, which will cause the lever 7 to generate additional pressure on the second elastic member 8, so that the rotation tendency of the first gear 6 is effectively restricted. Accordingly, as long as the end of the lever 7 has not separated from the first gear 6, the cover 2 will not separate from the hard disk 100.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
