[0003] In order to facilitate the MDVR's functions such as hard disk maintenance, replacement and data transmission, the hard disk box of some MDVRs is detachable, but due to space limitations, the disassembly and assembly structure is difficult to design. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a vehicle-mounted video recorder to solve the technical problem in the prior art that the hard disk disassembly and assembly structure is difficult to design due to space limitations.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a vehicle-mounted video recorder, including a main unit and a hard disk box detachably connected to the main unit, the main unit having a housing cavity for accommodating the hard disk box, the hard disk box including a hard disk body and a handle structure rotatably connected to the hard disk body, the handle structure being provided with an abutment portion, when the handle structure is rotated, the abutment portion abuts against the main unit to make the hard disk box move relative to the main unit, and the abutment portion is arranged away from the rotation axis of the handle structure.

[0006] In the above scheme, the vehicle video recorder includes a host and a hard disk box, and the hard disk box is detachably connected so that the hard disk box can be removed for maintenance and replacement. A handle structure is provided on the hard disk box, and when the handle structure is rotated, the abutment portion on the handle structure abuts against the host. As the handle structure gradually rotates, the hard disk box and the host gradually produce relative displacement, so that the hard disk box is removed from the host, and then the hard disk box can be directly pulled out by holding the handle structure. The setting of the abutment portion solves the problem of the hard disk box disassembly and assembly structure being difficult to design, and the handle structure has a simple structure and a low raw material cost.

[0007] Optionally, the handle structure includes a handle portion and an extension portion connected to each other. The handle portion and the extension portion are respectively disposed on opposite sides of the rotation axis. The abutting portion is connected to one side of the extension portion, and the abutting portion extends beyond the edge of the hard disk case.

[0008] In the above solution, by setting the handle structure as a handle portion and an extension portion connected to each other, the handle structure can be used for holding by hand, facilitating manual control of the rotation of the handle structure, and can also abut against the host, so that when the handle structure rotates, the relative movement between the hard disk case and the host can be realized.

[0009] Optionally, a hand-holding portion for holding by hand is provided on the side of the handle portion away from the rotation axis.

[0010] In the above solution, through the setting of the hand-holding portion, it is more convenient for the hand to apply a moment on the handle structure, avoiding opening the handle structure with sharp objects such as nails.

[0011] Optionally, an installation platform is convexly provided on the hard disk body, the handle structure is rotatably connected to the installation platform, and the installation platform is provided with an avoidance notch for avoiding the extension portion.

[0012] In the above solution, by providing an avoidance notch on the installation platform, the space required for the extension portion to rotate can be avoided, and interference between the extension portion and the installation platform during rotation can be avoided. The handle structure is rotatably connected to the installation platform, and an avoidance notch is designed on the installation platform, without the need to provide an avoidance notch on the hard disk body, ensuring that the internal space of the hard disk body is not affected.

[0013] Optionally, a handle hole is provided in the handle structure, and the hard disk body has a convex structure extending into the handle hole.

[0014] In the above solution, a handle hole is provided on the handle structure, and the user's finger can extend into the handle hole, making it more convenient to control the handle structure. At the same time, the mutual cooperation between the handle hole and the convex structure enables the handle structure to be positioned and cooperated with the hard disk body in the folded state, avoiding the handle structure from shaking relative to the hard disk body.

[0015] Optionally, a first clamping structure is provided at the handle hole of the handle structure, and the convex structure is provided with a second clamping structure for snap connection with the first clamping structure.

[0016] In the above solution, through the setting of the first clamping structure and the second clamping structure, the handle structure can be clamped to the hard disk body, preventing the handle structure from rotating without external force.

[0017] Optionally, the host includes a main body structure, a hard disk mounting rack disposed inside the main body structure, and a cover structure covering one end of the main body structure. The hard disk mounting rack has the accommodation cavity, and the hard disk box is in interference fit with the hard disk mounting rack.

[0018] In the above solution, the main body structure and the cover structure are connected to form an inner cavity. The hard disk mounting rack is disposed inside the inner cavity, and the hard disk box is in interference fit with the hard disk mounting rack, which is convenient for the assembly and fitting of the host. The hard disk box is connected with the hard disk mounting rack by interference fit, providing a pre-tightening force for the hard disk box and the host.

[0019] Optionally, at least one inner wall of the hard disk mounting rack is provided with a spring piece structure, and the spring piece structure is in mutual abutment with the surface of the hard disk box.

[0020] In the above solution, by providing the spring piece structure on the inner wall of the hard disk mounting rack to press against the hard disk box, a certain external force is required to pull out the hard disk box, which has a certain locking force on the hard disk box.

[0039] A mobile digital video recorder (MDVR for short, commonly known as in-vehicle DVR) integrates 4G and 5G video acquisition, GPS positioning management, and wireless transmission. It combines wireless communication technology, GPS global satellite positioning technology, and video surveillance technology and is the core product of a new generation of wireless in-vehicle video surveillance solutions. It is widely used in various mobile video surveillance fields such as buses, subways, trains, long-distance buses, taxis, logistics vehicles, private cars, and special vehicles (such as armored cars).

[0040] To meet the functions of convenient hard disk maintenance, replacement, and data transmission of MDVR, the hard disk boxes of some MDVRs are detachable. However, due to space limitations, it is difficult to design the disassembly and assembly structure.

[0041] To alleviate the above technical problems, the present utility model proposes a new in-vehicle video recorder. The in-vehicle video recorder includes a main unit 10 and a hard disk box 20 detachably connected to the main unit 10. When it is necessary to replace or repair the hard disk box 20 or perform data transmission, the hard disk box 20 can be detached from the main unit 10 without detaching the entire in-vehicle video recorder, and the operation is relatively convenient. A handle structure 22 is provided on the hard disk box 20. By rotating the handle structure 22, the main unit 10 can be pressed, causing relative movement between the main unit 10 and the hard disk box 20, releasing the locking force between the main unit 10 and the hard disk box 20, and then the hard disk box 20 can be taken out from the main unit 10.

[0042] The in-vehicle video recorder provided by the embodiments of the present utility model will now be described.

[0043] Please refer to Figures 1 to 3, the vehicle-mounted video recorder includes a main unit 10 and a hard disk box 20. The hard disk box 20 is detachably connected to the main unit 10, that is, the hard disk box 20 can be detached from the main unit 10 as needed or inserted into the main unit 10.

[0044] The main unit 10 is the main structure of the vehicle-mounted video recorder. It includes an external housing structure, and electronic devices such as a circuit board 14 can be arranged inside. The main unit 10 has a receiving cavity 120 for receiving the hard disk box 20, and the hard disk box 20 is placed inside the receiving cavity 120 during use. When the hard disk box 20 is inserted into the main unit 10, the hard disk box 20 is electrically connected to the electronic devices inside the main unit 10, allowing the main unit 10 to read, store, etc.

[0045] The hard disk box 20 includes a hard disk body 21 and a handle structure 22. The handle structure 22 is rotatably connected to the hard disk body 21. An abutting portion 223 is provided on the handle structure 22, and the abutting portion 223 is used to abut against the main unit 10. The handle structure 22 is rotatably connected to the hard disk body 21 through a rotating shaft. The abutting portion 223 is arranged deviating from the rotating shaft of the handle structure 22. That is to say, at least the side of the abutting portion 223 for abutting against the main unit 10 deviates from the rotating shaft and has a certain distance from the rotating shaft. In this way, when the handle structure 22 rotates, after the abutting portion 223 abuts against the main unit 10, the handle structure 22 continues to rotate, and the distance between the side of the abutting portion 223 abutting against the main unit 10 and the rotating shaft continuously increases, thereby causing the hard disk body 21 to have a relative displacement relative to the main unit 10, the hard disk body 21 is pulled outwards, and the locking force between the hard disk body 21 and the main unit 10 disappears, so that the hard disk body 21 can be directly pulled out.

[0046] Before the hard disk box 20 is disassembled, there is a locking force between the main unit 10 and the hard disk box 20, and a certain external force is required to pull out the hard disk box 20. At the same time, the handle structure 22 is in a folded state, that is, the handle structure 22 is arranged closely against the hard disk body 21. When disassembling the hard disk box 20, rotate the handle structure 22. After the abutting portion 223 abuts against the main unit 10, the handle structure 22 continues to rotate, causing the hard disk body 21 to have a relative displacement relative to the main unit 10, and the locking force between the main unit 10 and the hard disk box 20 disappears. At this time, the handle structure 22 can be set at 90 degrees or close to 90 degrees with the hard disk body 21. At this time, the handle structure 22 is in an unfolded state, and then grasp the handle structure 22 and pull out the hard disk box 20. When installing the hard disk box 20, directly insert the hard disk box 20 into the inside of the main unit 10.

[0047] The in-vehicle video recorder in the above embodiments includes a main unit 10 and a hard disk box 20. The hard disk box 20 is detachably connected so that the hard disk box 20 can be detached for maintenance and replacement. A handle structure 22 is provided on the hard disk box 20. When the handle structure 22 rotates, the abutting portion 223 thereon abuts against the main unit 10. As the handle structure 22 gradually rotates, a relative displacement is gradually generated between the hard disk box 20 and the main unit 10, causing the hard disk box 20 to disengage from the main unit 10, and then the hard disk box 20 can be directly pulled out by holding the handle structure 22. Through the setting of the abutting portion 223, the problem that it is difficult to design the disassembly and assembly structure of the hard disk box 20 is solved, and the structure of the handle structure 22 is simple and the raw material cost is also low.

[0048] In some embodiments of the present invention, please refer to Figures 3 to 6 , the handle structure 22 includes a handle portion 221 and an extension portion 222 connected to each other. The handle portion 221 and the extension portion 222 are respectively disposed on opposite sides of the rotation axis. The abutting portion 223 is connected to one side of the extension portion 222, and the abutting portion 223 extends beyond the edge of the hard disk box 20. The handle portion 221 is for hand-holding use. The side of the extension portion 222 close to the rotation axis is connected to the handle portion 221, and the side of the extension portion 222 close to the edge of the hard disk box 20 is connected to the abutting portion 223, so that the abutting portion 223 can extend beyond the edge of the hard disk box 20, thereby facilitating the abutment of the abutting portion 223 against the main unit 10. Combining Figure 3 , the rotation axis is vertically disposed, and the handle portion 221 and the extension portion 222 are respectively disposed on the left and right sides of the rotation axis.

[0049] By setting the handle structure 22 as a handle portion 221 and an extension portion 222 connected to each other, the handle structure 22 can not only be used for hand-holding, facilitating manual control of the rotation of the handle structure 22, but also can abut against the main unit 10, so that when the handle structure 22 rotates, relative movement between the hard disk box 20 and the main unit 10 can be realized.

[0050] In some embodiments, the abutting portion 223 is connected to the side of the extension portion 222 away from the rotation axis, making it easier for the abutting portion 223 to abut against the main unit 10.

[0051] In some embodiments, please refer to Figure 6 , the outer contour of the handle structure 22 is rectangular, and the outer contours of the handle portion 221 and the extension portion 222 are also square, so that the handle portion 221 and the extension portion 222 are spliced to form a rectangle.

[0052] In some embodiments, please refer to Figure 6 , in the direction parallel to the direction of the rotation axis, the length of the handle portion 221 is greater than the length of the extension portion 222. The longer length of the handle portion 221 is convenient for hand-holding control, and the shorter length of the extension portion 222 is to avoid squeezing more space of the main unit 10.

[0053] In some embodiments of the present utility model, please refer to Figure 5 and Figure 6 , a handle hole 224 is provided in the handle structure 22, and the hard disk body 21 has a protruding structure 212 extending into the interior of the handle hole 224. The handle hole 224 is for the hand to extend into, facilitating the hand to pull the handle structure 22. When the handle structure 22 is in the folded state, the protruding structure 212 is located inside the handle hole 224, and the outer contour dimension of the protruding structure 212 matches the inner contour dimension of the handle hole 224. When disassembling the hard disk case 20, when the handle structure 22 rotates from the folded state to the unfolded state, the user can insert the finger into the handle hole 224, facilitating the application of force to the handle structure 22.

[0054] A handle hole 224 is provided on the handle structure 22, and the user's finger can extend into the handle hole 224, making it more convenient to control the handle structure 22. At the same time, the mutual cooperation between the handle hole 224 and the protruding structure 212 enables the handle structure 22 to be positioned and cooperated with the hard disk body 21 when in the folded state, preventing the handle structure 22 from shaking relative to the hard disk body 21.

[0055] In some embodiments, the protruding structure 212 and the handle hole 224 are provided with an interference fit. In this way, when the handle structure 22 is in the folded state, the inner wall of the handle hole 224 presses against the protruding structure 212. Without external force, the handle structure 22 always remains in the folded state, preventing it from rotating relative to the hard disk body without external force.

[0056] In some embodiments of the present utility model, please refer to Figure 5 and Figure 6 , the handle structure 22 is provided with a first clamping structure 2241 at the handle hole 224, and the protruding structure 212 is provided with a second clamping structure 2121 for snap connection with the first clamping structure 2241. The first clamping structure 2241 at the handle hole 224 and the second clamping structure 2121 at the protruding structure 212 are snap-connected to lock the handle structure 22 to the hard disk body 21, keeping the handle structure 22 in the folded state. When it is necessary to open the handle structure 22, rotate the handle structure 22 forcefully to disengage the first clamping structure 2241 and the second clamping structure 2121, and the handle structure 22 can rotate freely.

[0057] Through the arrangement of the first clamping structure 2241 and the second clamping structure 2121, the handle structure 22 can be clamped to the hard disk body 21, preventing the handle structure 22 from rotating without external force.

[0058] In some embodiments, the first clamping structure 2241 is a clamping groove, and the second clamping structure 2121 is a clamping buckle. The clamping buckle is clamped inside the clamping groove, thereby realizing the snap connection between the handle structure 22 and the hard disk body 21.

[0059] In some embodiments, the first latching structure 2241 is a buckle, and the second latching structure 2121 is a slot. The buckle is latched inside the slot, thereby realizing the latching connection between the handle structure 22 and the hard disk body 21.

[0060] In some embodiments of the present utility model, please refer to Figure 6 , on the side of the handle portion 221 away from the rotation axis, there is a hand-held portion 225 for hand-holding. When a force is applied to the side of the handle portion 221 away from the rotation axis, the torque is larger and the handle structure 22 is easier to rotate. Therefore, the hand-held portion 225 is provided on the side of the handle portion 221 away from the rotation axis.

[0061] Through the setting of the hand-held portion 225, it is more convenient for the hand to apply a torque on the handle structure 22, and it is avoided to open the handle structure 22 with sharp objects such as nails.

[0062] In some embodiments, the hand-held portion 225 is a concave structure, and the finger can extend into the concave structure, which is convenient for the finger to apply a force to the handle structure 22.

[0063] In some embodiments of the present utility model, please refer to Figures 3 to 5 , the hard disk body 21 is provided with a raised mounting platform 211, the handle structure 22 is rotatably connected to the mounting platform 211, and the mounting platform 211 is provided with an avoidance notch 213 for avoiding the extension portion 222. The mounting platform 211 protrudes from the hard disk body 21 to provide a mounting position for the handle structure 22. When the handle structure 22 rotates, the handle portion 221 rotates towards the outside of the hard disk body 21, and the extension portion 222 moves towards the inside of the hard disk body 21. The avoidance notch 213 is used to avoid the space required for the extension portion 222 during rotation.

[0064] By providing the avoidance notch 213 on the mounting platform 211, the space required for the extension portion 222 during rotation can be avoided, and the interference between the extension portion 222 and the mounting platform 211 during rotation can be avoided. The handle structure 22 is rotatably connected to the mounting platform 211, and the avoidance notch 213 is designed on the mounting platform 211, so there is no need to provide an avoidance notch 213 on the hard disk body 21, ensuring that the internal space of the hard disk body 21 is not affected.

[0065] In some embodiments of the present utility model, please refer to Figure 1 and Figure 2, the host 10 includes a main body structure 11, a hard disk mounting rack 12 disposed inside the main body structure 11, and a cover body structure 13 covering one end of the main body structure 11. The hard disk mounting rack 12 has a receiving cavity 120, and the hard disk box 20 is press-fitted into the hard disk mounting rack 12. The main body structure 11 has an inner cavity, and main electronic devices, the hard disk box 20, etc. are all disposed inside the main body structure 11. One end of the main body structure 11 is open, and its open end is blocked by the cover body structure 13, and the cover body structure 13 is fixed at the open portion of the main body structure 11.

[0066] The main body structure 11 and the cover body structure 13 are connected to form an inner cavity. The hard disk mounting rack 12 is disposed inside the inner cavity, and the hard disk box 20 is press-fitted into the hard disk mounting rack 12, which is convenient for the assembly and fitting of the host 10. The hard disk box 20 is press-fitted and connected with the hard disk mounting rack 12, providing a pre-tightening force for the hard disk box 20 and the host 10.

[0067] In some embodiments, please refer to Figure 2 , the hard disk mounting rack 12 is similar to a drawer structure, and both of its sides are open. One side is blocked by a circuit board 14, and the other open side is for the hard disk box 20 to enter and exit. The circuit board 14 and the hard disk mounting rack 12 enclose the receiving cavity 120. When the hard disk box 20 is located in the receiving cavity 120, the hard disk box 20 is electrically connected to the circuit board 14.

[0068] In other embodiments, the hard disk mounting rack 12 is a structure with one end open, and this open side is for the hard disk box 20 to enter and exit.

[0069] In some embodiments of the present utility model, please refer to Figure 7 , at least one inner wall of the hard disk mounting rack 12 is provided with a spring piece structure 121, and the spring piece structure 121 abuts against the surface of the hard disk box 20. When the spring piece structure 121 of the hard disk mounting rack 12 abuts against the surface of the hard disk box 20, the spring piece structure 121 deforms, and the elastic return force of the spring piece structure 121 acts on the hard disk box 20. Therefore, a locking force on the hard disk box 20 is formed, and a certain external force is required to pull out the hard disk box 20.

[0070] By providing the spring piece structure 121 on the inner wall of the hard disk mounting rack 12 to press against the hard disk box 20, the hard disk box 20 requires a certain external force to be pulled out, having a certain locking force on the hard disk box 20. At the same time, the anti-vibration ability of the vehicle-mounted video recorder can be improved, avoiding the hard disk box 20 shaking inside the host 10 during vehicle-mounted use.

[0071] In some embodiments, spring piece structures 121 are provided on each side wall of the hard disk mounting rack 12, making the hard disk box 20 more stable inside the hard disk mounting rack 12.

[0072] In some embodiments, a through hole for avoiding the elastic piece structure 121 is formed in the side wall of the hard disk mounting bracket 12, and the elastic piece structure 121 is cantilever-connected to the inner wall of the through hole, so that the elastic piece structure 121 can be deformed under pressure.

[0073] In some embodiments, a limiting protrusion 122 is provided on a part of the side wall of the hard disk mounting bracket 12, and the limiting protrusion 122 abuts against the surface of the hard disk cartridge 20, and can also provide a certain locking force for the hard disk cartridge 20.

[0074] In some embodiments, please refer to Figure 7 , an elastic piece structure 121 is provided on a side wall of the hard disk mounting bracket 12 facing the circuit board 14, and limiting protrusions 122 are provided on both of two opposite side walls. In this way, the hard disk cartridge 20 is provided with locking forces in at least two directions.

[0075] In some embodiments of the present utility model, please refer to Figure 1 , the cover body structure 13 includes a cover plate 131 and a cover door 132 rotatably connected to the cover plate 131. The cover plate 131 is fixedly connected to the main body structure 11. An opening for exposing the hard disk cartridge 20 is formed in the cover plate 131, and the cover door 132 is used to cover the opening. When the cover plate 131 is fixedly connected to the main body structure 11, the edge of the cover plate 131 is fixedly connected to the end wall of the main body structure 11. The cover door 132 can rotate relative to the cover plate 131 to expose or block the opening on the cover plate 131. Specifically, when the hard disk cartridge 20 needs to be taken out, the cover door 132 is opened to expose the hard disk cartridge 20, and then the handle structure 22 is rotated to pull out the hard disk cartridge 20.

[0076] Through the arrangement of the cover door 132, the hard disk cartridge 20 can be enclosed inside the host 10.
