[0017] This application provides a bracket assembly 10 for use in a dashcam.

[0018] This application provides a dashcam, which includes a main body shell 20, a circuit board assembly 30, a power supply 40, and a bracket assembly 10 provided in any embodiment of this application. The circuit board assembly 30, the power supply 40, and the bracket assembly 10 are all located inside the main body shell 20, and the power supply 40 is electrically connected to the circuit board assembly 30.

[0019] Please refer to this simultaneously. Figure 2 , Figure 4 and Figure 5 The bracket assembly 10 includes a first bracket 11 and a second bracket 12. The first bracket 11 has a first side 111 and a second side 112 facing away from each other along a first direction. The first side 111 is used to mount the circuit board assembly 30. The second bracket 12 is disposed on the second side 112 of the first bracket 11. The second bracket 12 and the first bracket 11 enclose a first receiving space for accommodating a power supply 40. The power supply 40 is disposed within the first receiving space.

[0020] In this embodiment, a bracket assembly 10 is used to provide installation and support for both the circuit board assembly 30 and the power supply 40. This makes the structure compact. On the other hand, the circuit board assembly 30 and the power supply 40 are located on opposite sides of the first bracket 11, that is, the first bracket 11 separates the circuit board assembly 30 and the power supply 40, which helps to reduce the mutual interference between the heat generated by the circuit board assembly 30 and the heat generated by the power supply 40, thereby reducing the risk of overheating.

[0021] In some embodiments, the first bracket 11 has at least two snap-fit ​​slots 1121, which are spaced apart along a second direction. The second bracket 12 is inserted into the corresponding snap-fit ​​slots 1121 on both sides of the second direction to achieve snap-fit ​​between the second bracket 12 and the first bracket 11. This achieves a detachable connection between the second bracket 12 and the first bracket 11. Furthermore, the snap-fit ​​slots 1121 can position the second bracket 12. During assembly, the second bracket 12 simply snaps into the snap-fit ​​slots 1121 on both sides of the second direction, resulting in a simple structure and convenient operation.

[0022] In some embodiments, such as Figure 6 As shown, a plurality of ribs 1122 are formed on the surface of the second side 112 of the first bracket 11. The plurality of ribs 1122 surround and form a receiving groove 1123, which is used to accommodate the power supply 40. In this way, the receiving groove 1123 can limit the position of the power supply 40, so that the power supply 40 can be more stably positioned in the bracket assembly 10.

[0023] For example, the plurality of protrusions 1122 include a first protrusion 1122a and two second protrusions 1122b, the two second protrusions 1122b being arranged opposite each other along a second direction, the first protrusion 1122a being connected to one end of the two second protrusions 1122b along a third direction respectively, the other ends of the second protrusions 1122b along the third direction being spaced apart to form an opening 22a, the first protrusion 1122a being used to provide support for one end of the power supply 40 along the third direction, the third direction being substantially perpendicular to the first direction.

[0024] In this embodiment, the first rib 1122a and the two second ribs 1122b enclose and form a receiving groove 1123. The first rib 1122a provides support for the power supply 40 in a third direction, and the two second ribs 1122b limit the movement of the power supply 40 in a second direction. This reduces the swaying of the power supply 40 in the second direction. In this embodiment, the other ends of the second ribs 1122b in the third direction are spaced apart to form openings 1123a, through which the power supply 40 can enter the receiving groove 1123. It is understood that the power supply 40 can also enter the receiving groove 1123 in the first direction.

[0025] It should be noted that when a dashcam is installed in a vehicle to record images, the third direction is roughly the height of the vehicle, the first direction is roughly the front-to-back direction of the vehicle, and the second direction is roughly the left-to-right direction of the vehicle.

[0026] In some embodiments, please refer to Figure 6 The support assembly 10 includes a retaining rib 14, which is disposed on the second side 112. The retaining rib 14 and the first protruding rib 1122a are arranged opposite each other along a third direction. The retaining rib 14 is used to limit the other end of the power supply 40 along the third direction. This helps to reduce the shaking of the power supply 40 along the third direction. In this embodiment, the battery can enter the receiving groove 1123 along the first direction, and then be positioned within the receiving groove 1123 at its upper limit in the second and third directions.

[0027] In some embodiments, the bracket assembly 10 includes a flexible limiting member 15, and the second bracket 12 has a first wall portion 121, which is disposed opposite to the second side 112 along a first direction. The first wall portion 121 has a through hole 121a, and the flexible limiting member 15 is disposed in the through hole 121a to limit the power supply 40 along the first direction.

[0028] It is understandable that the flexible limiting member 15 can be interference-fitted with the through hole 121a or clearance-fitted with the through hole 121a.

[0029] For example, the flexible limiting member 15 protrudes from the through hole 121a on the side away from the power source 40 along the first direction and can contact the display screen 70 described below. That is, the display screen 70 can limit the flexible limiting member 15 along the first direction, further ensuring that the flexible limiting member 15 limits the power source 40 along the first direction.

[0030] The flexible limiting component 15 can be, for example, a sponge component, a polyurethane foam component, etc.

[0031] In some embodiments, such as Figure 5 As shown, the support assembly 10 includes at least one connecting ear 13, which is connected to at least one side of the second support 12 along a second direction, and the connecting ear 13 is used to connect to the main body shell 20.

[0032] In this embodiment, at least one connecting ear 13 is connected to at least one side of the second bracket 12 along the second direction. Specifically, at least one connecting ear 13 may be connected to one side of the second bracket 12 along the second direction. In this embodiment, the number of connecting ears 13 may be one or more, but all connecting ears 13 are connected to one side of the second bracket 12 along the second direction. Alternatively, at least one connecting ear 13 may be connected to both sides of the second bracket 12 along the second direction. In this embodiment, the number of connecting ears 13 is at least two.

[0033] By connecting the connecting ear 13 to at least one side of the second bracket 12 along the second direction, the connecting ear 13 can be connected to the main body shell 20, thereby fixing the bracket assembly 10 within the main body shell 20. While fixing the bracket assembly 10, the size of the bracket assembly 10 along the first direction will not be increased, which helps to make the dashcam structure compact along the first direction.

[0034] For example, the connecting ear 13 is formed with a connecting hole for the first connector 50, which is connected to the main body shell 20, to pass through. The first connector 50 enables the connection between the connecting ear 13 and the main body shell 20.

[0035] For example, the connecting ear 13 and the second bracket 12 are an integral structure. This helps to increase the connection stability between the connecting ear 13 and the second bracket 12, while reducing the assembly of the connecting ear 13 and the second bracket 12.

[0036] In some embodiments, the main shell 20 includes a cover 21 and a shell 22. The shell 22 has an opening 22a at one end in the third direction that communicates with the first receiving space, and the cover 21 is disposed at the opening 22a. That is, the cover 21 and the shell 22 together form the main shell 20.

[0037] For example, the second bracket 12 is smaller in the third direction than the first bracket 11, so that a heat dissipation gap is formed between the second bracket 12 and the cover 21. The heat dissipation gap facilitates power supply heat dissipation.

[0038] For example, the dashcam includes a first connector 50 and a first connecting portion 23 on the housing 22. The first connector 50 passes through the cover 21 and the connecting ear 13 in sequence and then connects to the first connecting portion 23. In this way, the housing 22 and the cover 21 are fixed, and the second bracket 12 is also fixed, thereby fixing the bracket assembly 10 inside the housing 22, which helps to make the structure compact.

[0039] During the assembly of the dashcam, various components such as the bracket assembly 10, circuit board assembly 30, and power supply 40 can be installed into the housing 22 first, and the connecting ear 13 can be aligned with the first connecting part 23. Then, the first connecting piece 50 passes through the cover 21 and the connecting ear 13 and connects to the first connecting part 23, thereby realizing the assembly of the dashcam.

[0040] The structure of the first connector 50 is not limited; for example, it can be an external threaded pin, a self-tapping pin, etc.

[0041] It is understood that the number of the first connecting part 23 and the number of the first connecting member 50 are not limited, but the number of both must be the same so that the cover 21 and the first connecting part 23 can be connected by the first connecting member 50.

[0042] For example, when projected onto a plane perpendicular to the thickness direction of the cover 21, the projections of both the cover 21 and the housing 22 are rectangular. The first connecting portion 24 is located at at least one corner of the housing 22, and the first connecting member 50 passes through at at least one corner of the cover 21. This helps to make the structure compact.

[0043] It should be noted that the corners, including the corners of the cover 21 and the shell 22, are either right angles or rounded corners.

[0044] For example, there are two connecting ears 13, which are respectively connected to the two sides of the second bracket 12 along the second direction.

[0045] In some embodiments, the circuit board assembly 30 includes at least two circuit boards 31, which are arranged along a first direction and spaced apart. This allows the circuit boards 31 to have space for various functional components, and also facilitates heat dissipation for the circuit boards 31 and the functional components disposed on them.

[0046] In some embodiments, the circuit board 31 has mounting holes, and the circuit board assembly 30 includes a second connector 32 that passes through all the mounting holes of the circuit boards 31 and is connected to a first side 111 of the first bracket 11.

[0047] For example, such as Figure 4 As shown, the circuit board assembly 30 also includes at least one spacer retaining cylinder 34, which is sleeved on the second connector 32 and located between two adjacent circuit boards 31. This ensures the spacing between two adjacent circuit boards 31.

[0048] In some embodiments, the circuit board assembly 30 includes a flexible printed circuit board connector 33, through which at least two adjacent circuit boards 31 are electrically connected. The flexible printed circuit board connector 33 is relatively thin and flexible, occupies little space, and can achieve high-density wiring in a confined space.

[0049] In some embodiments, the dashcam includes heat insulation 110, which is disposed between the power supply 40 and the second side 112. On the one hand, this facilitates heat dissipation of the power supply 40 itself; on the other hand, it further isolates the power supply 40 from the circuit board assembly 30 disposed on the first side 111 of the first bracket 11, further reducing the mutual interference between the heat of the circuit board assembly 30 and the heat of the power supply 40.

[0050] In some embodiments, the dashcam includes a camera assembly 60 electrically connected to a circuit board assembly 30. The camera assembly 60 is disposed within and partially exposed within the main housing 20, and is located on the side of the circuit board assembly 30 away from the bracket along a first direction. This arrangement, where the camera assembly 60, circuit board assembly 30, and power supply 40 are stacked along the first direction, results in a compact structure, at least contributing to a reduction in the dimensions of the main housing 20 along the second and third directions.

[0051] In some embodiments, the dashcam includes a display screen 70, which is electrically connected to the circuit board assembly 30. The display screen 70 is embedded in the shell wall of the main body housing 20 and is located on the side of the bracket assembly 10 facing away from the circuit board assembly 30 along a first direction. By embedding the display screen 70 in the shell wall of the main body housing 20, the space occupied by the display screen 70 is reduced, making the dashcam structurally compact in the first direction. Moreover, the display screen 70 and the camera assembly 60 are exposed from opposite sides of the main body housing 20 along the first direction. When the dashcam is installed in the vehicle, the camera assembly 60 generally faces the front of the vehicle for easy recording, while the display screen 70 faces the interior of the vehicle for easy viewing by the user.

[0052] In some embodiments, such as Figure 1 , Figure 3 and Figure 7 As shown, the dashcam also includes a base housing 80, which is used to connect to the vehicle, and the main body housing 20 is connected to the base housing 80.

[0053] For example, the dashcam also includes a pivot 90 and a damping element. The pivot 90 is located between the seat housing 80 and the main body housing 20. The pivot 90 has a first axis X1 and a second axis X2 (see [link to dashcam description]). Figure 3 The rotating shaft 90 is rotatably connected to the main body shell 20 along the first axis X1 and to the seat shell 80 along the second axis X2. A damping element is provided between the rotating shaft 90 and the main body shell 20 to generate rotational damping when the rotating shaft 90 rotates along the first axis X1 and the main body shell 20. A damping element is also provided between the rotating shaft 90 and the seat shell 80 to generate rotational damping when the rotating shaft 90 rotates along the second axis X2 and the seat shell 80. The second axis X2 is perpendicular to the first direction, and the first axis X1 and the second axis X2 intersect.

[0054] In this embodiment, the base shell 80 can rotate relative to the main shell 20 about a first axis X1 and also about a second axis X2 via a pivot, making the relative position and angle of the base shell 80 and the main shell 20 adjustable. After rotation, the base shell 80 can be maintained at the adjusted position and angle by a damping element.

[0055] Wherein, the second axis X2 is perpendicular to the first direction, and the first axis X1 and the second axis X2 intersect. Optionally, the first axis X1 and the second axis X2 are perpendicular. That is, the extension direction of the first axis X1 is parallel to the third direction, and the second axis X2 is parallel to the second direction.

[0056] Rotational damping refers to the ability to provide resistance or slow down rotation during rotation, achieving smooth, stable, and controllable rotational motion while reducing vibration, noise, and mechanical shock. Specifically, firstly, rotational damping ensures that rotational movements are not abrupt but rather a uniform and smooth transition from one angle to another, providing a comfortable user experience. Secondly, rotational damping allows the user to precisely stop at the desired angle. Thirdly, rotational damping absorbs kinetic energy during rotation, reducing vibration and noise, making rotation quieter and smoother.

[0057] This application does not impose any special limitations on the material of the damping element. Exemplarily, the material of the damping element is one of rubber, silicone, or composite materials.

[0058] The base housing 80 is used to connect to the vehicle. A suction cup, adhesive layer, etc., can be installed on the side of the base housing 80 away from the main housing 20 to fix the dashcam inside the vehicle. In actual use, the base housing 80 is fixed to the car window, and the main housing 20 is rotated to point the camera on the main housing 20 towards the front of the vehicle for recording road conditions. Users can also rotate the main housing 20 to point the camera at other locations for recording, depending on their needs.

[0059] Since the pivot 90 can rotate relative to the main body shell 20 around the first axis X1 and the second axis X2, the position and angle of the main body shell 20 relative to the base shell 80 can be adjusted to achieve omnidirectional adjustment. Because a damping element generates rotational damping when the pivot 90 rotates, after adjusting the relative orientation of the main body shell 20 and the base shell 80, the pivot can remain in the adjusted orientation, and the adjustment feel is also good.

[0060] In some embodiments, the dashcam includes a GPS (Global Positioning System) module, which is located in the housing 80. This enables the dashcam to not only have video recording capabilities but also location tracking functionality.

[0061] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
