Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted data recorders, and in particular to a housing of a vehicle-mounted data recorder. Background Art

[0002] An on-board data recorder is an instrument used to record images, sounds, and other related information while a vehicle is driving. It is installed directly on the vehicle during use, so it can also record images of the accident process after the vehicle is involved in an accident. However, due to the violent collisions that may occur in accidents, the on-board data recorder may be damaged in the event of a collision, making it impossible to record and store images.

[0003] Chinese patent application number CN202221313611.8 discloses an impact-resistant adjustable vehicle-mounted data recorder, including a shell, a detachable clip for installing a storage component inside the shell, adjustment slots perpendicular to the bottom of the shell are provided on the adjacent two side walls of the shell, and the side walls of the detachable clip are provided with adjustment columns adapted to the adjustment slots. An indicator light circuit board is installed on the inner top wall of the shell, and a vehicle-mounted data recorder is installed inside the shell.

[0004] The above solution only protects the storage component. However, if the onboard data recorder is damaged at the moment of the collision, it will not be able to record the vehicle image after the collision, thereby affecting the restoration of the vehicle collision scene.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to enhance the protection strength of the vehicle-mounted data recorder, the present application provides a vehicle-mounted data recorder housing.

[0007] This application provides a vehicle-mounted data recorder housing, which adopts the following technical solutions:

[0008] A vehicle-mounted data recorder housing includes an upper shell with two openings, a bottom plate arranged at the lower opening of the upper shell, and a connector panel arranged at the opening of the upper shell adjacent to the bottom plate. Mounting feet are provided on two side walls of the upper shell that are separated from each other, and the lower end surfaces of the mounting feet are arranged lower than the lower end surface of the bottom plate. A circuit board is arranged in the inner cavity of the upper shell.

[0009] By adopting the above technical solution, the lower end of the base plate will not directly contact the vehicle structure during the installation process, so that the vibration generated during the vehicle collision will not be directly transmitted to the circuit board through the base plate, making the electronic components on the circuit board less susceptible to impact from the base plate, thereby improving the service life of the circuit board.

[0010] Optional: A recessed portion protruding toward the interior of the upper shell is provided on the top wall of the inner cavity of the upper shell, the part of the recessed portion located in the inner cavity of the upper shell abuts against the chip on the circuit board, and the upper end surface of the upper shell is provided with a relief groove connected to the inner cavity of the recessed portion, and a number of internal heat dissipation components are provided in the relief groove.

[0011] By adopting the above technical solution, the heat on the chip on the circuit board is dissipated into the air by utilizing the recessed portion and the internal heat sink therein, so that the heat of the chip will not be too high and the circuit board can be used normally.

[0012] Optionally, a plurality of external heat dissipating elements are provided on the upper end surface of the upper shell, and the external heat dissipating elements close to the internal heat dissipating elements are connected to the internal heat dissipating elements.

[0013] By adopting the above technical solution, the contact area between the upper shell and the air is further increased by utilizing the external heat dissipating element, thereby improving the cooling effect of the heat generated by the circuit board inside the upper shell.

[0014] Optional: The upper end surface of the upper shell is provided with a sinking groove, which penetrates the three side walls of the upper shell away from the connector panel, and the external heat dissipating element is provided in the sinking groove, and the upper end surface of the external heat dissipating element is flush with the upper end surface of the upper shell.

[0015] By adopting the above technical solution, during the transportation and installation process, the external heat sink is not easily deformed due to collision, so that the heat dissipation effect of the external heat sink is not easily affected. At the same time, during the collision, the deformation of the external heat sink itself can also reduce the impact on the upper shell, so that the circuit board is not easily subjected to excessive impact.

[0016] Optionally, two extensions are provided on the end surface of the upper shell on which the connector panel is provided, and the extensions are respectively provided on the sides of the connector panel that are away from each other.

[0017] By adopting the above technical solution, after the plug is connected to the connector panel, the extension portion can protect the plug, making it less likely for the plug to be impacted and fall off the connector panel directly, so that the circuit board can still be connected to the camera element on the vehicle after the vehicle is impacted.

[0018] Optionally, a plurality of reinforcing parts are provided at one end of the upper shell away from the connector panel, and the side walls of the reinforcing parts that are away from each other are flush with the side walls of the upper shell where the mounting feet are provided.

[0019] By adopting the above technical solution, the connection position between the socket and the plug located on the side of the upper shell away from the connector panel can be protected by the reinforcement part.

[0020] Optionally: a plurality of upper reinforcing ribs are provided on the top wall of the inner cavity of the upper shell, and the upper reinforcing ribs are arranged in an array and their ends are connected to the inner wall of the upper shell.

[0021] By adopting the above technical solution, the upper end surface of the upper shell is strengthened by the upper reinforcing ribs, so that the upper end surface of the upper shell will not directly deform downward when subjected to downward pressure.

[0022] Optionally: a plurality of lower reinforcing ribs are provided on the end surface of the bottom plate close to the upper shell, the lower reinforcing ribs are arranged in an array, and the ends of the lower reinforcing ribs abut against the side wall of the inner cavity of the upper shell.

[0023] By adopting the above technical solution, the strength of the bottom plate is enhanced by utilizing the lower reinforcement, so that the bottom plate is not easily deformed upward when subjected to force, and the circuit board is not easily affected.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The mounting feet prevent the bottom plate from directly contacting the vehicle structure, so that when the vehicle is hit, the vibration is not easily transmitted directly to the circuit board, making the circuit board less susceptible to impact;

[0026] 2. The heat dissipation of the upper shell as a whole is carried out through the external heat sink, so that the heat generated during the operation of the circuit board can be dissipated, so that the circuit board can work normally. At the same time, the external heat sink can also produce deformation and absorb impact, reducing the impact force on the circuit board. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] The present application discloses a vehicle-mounted data recorder housing, such as Figure 1 and Figure 2As shown, the upper shell 1 comprises a bottom plate 2 disposed at the lower end of the upper shell 1, and a connector panel 3 disposed on one side wall of the upper shell 1. The lower end face and one side wall of the upper shell 1 are open. The bottom plate 2 is fixed to the upper shell 1 with bolts, thereby closing the lower end opening of the upper shell 1. The connector panel 3 is also fixed to the upper shell 1 and the bottom plate 2 with bolts, thereby closing the opening on one side wall of the upper shell 1. The inner cavity of the upper shell 1 is provided with a plurality of mounting blocks 11. The circuit board is mounted on the mounting blocks 11 with bolts, leaving a gap between the upper end of the circuit board and the top of the inner cavity of the upper shell 1. Two mounting feet 12 are fixed to the two side walls of the upper shell 1 adjacent to its side openings. The two mounting feet 12 are respectively arranged near the ends of the side walls, and the lower end surfaces of the mounting feet 12 extend downward, so that the lower end surface of the mounting feet 12 is lower than the lower end surface of the bottom plate 2. When the mounting feet 12 are fixed to the vehicle, when the vehicle is hit, the vibration will not be directly transmitted to the circuit board in the upper shell 1 through the bottom plate 2, so that the circuit board can still work normally and capture images in the event of a collision.

[0033] Because the chip mounted on the circuit board continuously generates heat during operation, a downwardly recessed recess 13 is provided on the top wall of the inner cavity of the upper shell 1. The recess 13 is hollow, and the lower end of the recess 13 abuts the surface of the chip on the circuit board. A relief groove 14 is provided on the upper end surface of the upper shell 1, communicating with the inner cavity of the recess 13. Within the relief groove 14 are several internal heat sinks 15 flush with the openings of the relief grooves 14. The internal heat sinks 15 are plate-shaped and arranged in an array within the relief grooves 14, maintaining contact with the inner walls of the relief grooves 14. Therefore, when the chip generates heat, the heat is transferred through the recess 13 to the internal heat sinks 15, and then transferred to the air through the internal heat sinks 15, thereby dissipating heat from the chip.

[0034] In order to further improve the heat dissipation effect inside the upper shell 1, a number of external heat dissipating members 16 are further provided on the upper end surface of the upper shell 1. The external heat dissipating members 16 are arranged in a plate shape and arranged in one direction. The external heat dissipating members 16 are connected to the internal heat dissipating members 15 close to them, thereby utilizing the external heat dissipating members 16 to further increase the contact area between the upper shell 1 and the air, thereby improving the heat dissipation efficiency.

[0035] To prevent the external heat sink 16 from being easily deformed by impact during installation, the end surface of the upper shell 1 on which the external heat sink 16 is provided is also provided with a sinking groove 141. The sinking groove 141 penetrates the three vertical side walls of the upper shell 1 away from the connector panel 3. The external heat sink 16 is arranged on the bottom surface of the sinking groove 141, and the upper end surface of the external heat sink 16 remains flush with the upper end surface of the upper shell 1. When the upper end surface of the upper shell 1 is subjected to force, the upper end of the upper shell 1 can be subjected to force without directly deforming the upper heat sink, which makes the heat dissipation effect less likely to be affected. In addition, in the event of a vehicle collision, the upper heat sink can deform and absorb part of the impact, thereby reducing the impact force on the circuit board inside the upper shell 1.

[0036] Since the circuit board inside the upper shell 1 and the component with a camera function on the vehicle need to be connected by a plug connected to the connector panel 3, in order to prevent the connection between the plug and the connector panel 3 from being affected in the event of a vehicle collision, two extensions 17 are integrally formed on the side wall of the upper shell 1 where the connector panel 3 is located. The two extensions 17 are respectively located at opposite ends of the connector panel 3, and the distance between the side wall of the extension 17 away from the upper shell 1 and the upper shell 1 is greater than the distance between the end of the plug away from the upper shell 1 and the upper shell 1. Therefore, in the event of an impact, the plug is less likely to be directly squeezed and thus lose connection with the connector panel 3, allowing the component with a camera function on the vehicle to still transmit data to the storage unit on the circuit board for storage.

[0037] The side wall of the upper housing 1 facing away from the connector panel also features a socket for connecting to a circuit board. This socket can easily disengage a plug connected to the socket during a vehicle collision. Therefore, two reinforcements 18 are also provided on the side wall of the upper housing 1 facing away from the connector panel 3. These reinforcements 18 are positioned adjacent to the two vertical side walls adjacent to this side wall, with the two side walls facing away from each other flush with the side wall of the upper housing 1 adjacent to the connector panel 3. These reinforcements 18 prevent the plug connected to this portion of the upper housing 1 from disengaging from the socket, ensuring that the circuit board within the upper housing 1 remains functional after a vehicle collision.

[0038] like Figure 2 As shown, to prevent deformation of the upper end surface of the upper shell 1 even when subjected to external forces, a plurality of upper reinforcing ribs 19 are integrally formed on the top wall of the inner cavity of the upper shell 1. The upper reinforcing ribs 19 are crisscrossed and their ends are connected to the inner wall of the upper shell 1. The upper reinforcing ribs 19 near the connector panel 3 abut the side wall of the connector panel 3 near the upper shell 1. The upper reinforcing ribs 19 enhance the strength of the upper end surface of the upper shell 1, preventing the upper end of the upper shell 1 from deforming downward under force, and ensuring the normal operation of the circuit board within the upper shell 1.

[0039] like Figure 3As shown, to prevent the bottom plate 2 from deforming even when subjected to stress, a plurality of lower reinforcing ribs 21 are provided on the end surface of the bottom plate 2 near the upper shell 1. The lower reinforcing ribs 21 are arranged in an array, and the ends of the reinforcing ribs respectively abut the inner wall of the upper shell 1 and the connector panel 3. When the bottom plate 2 is subjected to stress, the lower reinforcing ribs 21 provide support, preventing the bottom plate 2 from deforming, and further improving the stability of the circuit board.

[0040] The implementation principle of this embodiment is: when in use, the circuit board is first placed in the upper shell 1 and fixed with bolts, and then the connector panel 3 is fixed to the upper shell 1 and then the bottom plate 2 is fixed. Then, the upper shell 1 is installed on the vehicle through the mounting feet 12. The mounting feet 12 are used to prevent the bottom plate 2 from directly contacting the vehicle, thereby reducing the amount of vibration transmitted to the circuit board.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
