Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat dissipation mechanisms for dashcam camera modules, specifically to a heat dissipation mechanism for dashcam camera modules. Background Technology
[0002] With the development of society, the application of dashcams has become more widespread. A dashcam is an instrument that records images and sounds during a vehicle's journey. After installing a dashcam, it records video while driving, and records the time, speed, and location in the video. The dashcam continues to work during long driving sessions, so it is necessary to cool it down during extended use, otherwise it will directly affect the use of the dashcam.
[0003] The current publication number CN216527313U discloses a heat dissipation mechanism for a dashcam, including a dashcam body. A connecting mechanism is symmetrically fixedly installed at the upper and lower ends of the dashcam body. The connecting mechanism includes a connecting rod and a limiting frame. The right side surface of the connecting rod is inserted into the interior of the limiting frame, and a fixing block is inserted through the right side interior of the limiting frame. A pull rod is fixedly connected to the right side surface of the fixing block, and a first pull plate is fixedly connected to the top surface of the pull rod. This invention, by providing a connecting mechanism, allows the connecting rod to engage inside the limiting frame during use. At this time, the fixing block, through the elastic force of the first spring, can be inserted into the interior of the connecting rod. This allows the heat dissipation device to be externally connected to the dashcam body, facilitating the individual disassembly and replacement of the heat dissipation components installed on the dashcam body, thereby reducing the cost of replacing the dashcam body.
[0004] To address the heat dissipation issue of dashcam cameras in the aforementioned solutions, existing technologies employ a connecting mechanism. During use, a connecting rod engages with the inside of a limiting frame, and a fixing block is inserted into the connecting rod by the elastic force of a first spring. This allows the heat dissipation device to be externally connected to the dashcam body. However, this approach still results in poor heat dissipation and an inability to cool down quickly, leading to a shorter lifespan for the dashcam. Utility Model Content
[0005] The purpose of this invention is to provide a heat dissipation mechanism for a dashcam camera module to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A heat dissipation mechanism for a dashcam camera module includes a housing, a lens assembly fitted onto the surface of the housing, a focusing motor driven to one end of the lens assembly, an image sensor mounted on one end of the focusing motor, a circuit connection substrate mounted on one side of the image sensor, a heat dissipation mechanism mounted on one side of the circuit connection substrate, a sealing plate mounted on the rear side of the housing, a through groove formed on the surface of the sealing plate, and fixing mechanisms mounted on both sides of the housing.
[0008] The heat dissipation mechanism includes an adhesive patch, which is bonded to the rear side of the circuit connection substrate. One side of the adhesive patch is fixedly connected to the surface of the protective layer. Vertical grooves are equidistantly provided at the bottom end of the protective layer. A handle is fixedly connected to the bottom of the protective layer. Pulling the handle will cause the entire mechanism to move outward, thus completing the disassembly work.
[0009] A further improvement of this utility model is that a movable plate is installed on the surface of the protective layer, and a heat dissipation groove is formed on the surface of the movable plate, so that the main heat dissipation work of the movable plate can be carried out through the setting of the heat dissipation groove.
[0010] A further improvement of this utility model is that: a heat-conducting block is fixedly connected to the surface of the movable plate, auxiliary ventilation slots are provided on both sides of the movable plate, a compression spring is fixedly connected to the bottom of the movable plate, and limit keys are fixedly connected to both sides of the movable plate. By opening the auxiliary ventilation slots inside the side ends of the auxiliary ventilation slots, it is possible to control the flow of energy through the inside of the movable plate, which facilitates the heat dissipation work inside the movable plate.
[0011] A further improvement of this utility model is that: the protective surface layer is made of asbestos, and anti-slip textures are provided on both sides of the protective surface layer. The protective surface layer also has slots on both sides that are compatible with the limit key. Through the setting of the vertical slots, the moving piece can be basically protected to prevent external objects from damaging the surface of the moving piece, and at the same time, the heat dissipation efficiency can be improved.
[0012] A further improvement of the present invention is that the fixing mechanism includes a movable block and a locking frame. The movable block is fixedly connected to both sides of the outer shell, and a spring is fixedly connected to one side of the inner side of the movable block. The locking frame is fixedly connected to both sides of the sealing plate. By pressing down the toggle block, the locking frames on both sides of the sealing plate are engaged into the interior of the locking block, thereby engaging the locking block into the interior of the locking frame, thus fixing the sealing plate to the outer shell.
[0013] A further improvement of this utility model is that: one end of the spring is fixedly connected to a toggle block, one end of the toggle block is fixedly connected to a locking block, and a movable groove is provided on one side of the movable block. When the sealing plate is moved, the toggle block is moved, and the toggle block is squeezed by the spring, which drives the locking block to move backward, so that the locking block is disengaged from the locking frame, thereby allowing the sealing plate to be separated from the outer shell, achieving the function of convenient movement and disassembly.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a heat dissipation mechanism for a dashcam camera module. An adhesive sticker is directly attached to the rear end of the circuit connection substrate, allowing for easy installation. Simultaneously, a compression spring continuously presses inward, causing a movable piece to contact the rear end of the device, facilitating heat conduction. During the movement of the movable piece, a limit key slides into a sliding groove inside the protective surface layer, ensuring the movable piece moves vertically in a straight line. When the movable piece is conducting heat transfer, the heat dissipation groove facilitates primary heat dissipation. Additionally, an auxiliary ventilation groove located on the side allows for controlled flow through the interior of the movable piece, facilitating internal heat dissipation. This results in rapid heat dissipation and conduction, extending the device's lifespan.
[0016] 2. This utility model provides a heat dissipation mechanism for a dashcam camera module. When it is necessary to fix the outer shell and the cover plate, by pressing down the toggle block, the locking frames on both sides of the cover plate are engaged with the inside of the locking block, thereby fixing the cover plate and the outer shell. When it is necessary to move the cover plate, the toggle block is moved, and the toggle block is squeezed by the spring, causing the locking block to move backward, so that the locking block disengages from the locking frame, thereby detaching the cover plate from the outer shell, achieving the function of convenient movement and disassembly, and facilitating the replacement and maintenance of the heat dissipation mechanism and the camera.

[0022] The present invention will be further described in detail below with reference to embodiments:
[0023] Example 1
[0024] like Figure 1-4 As shown, this utility model provides a heat dissipation mechanism for a dashcam camera module, including a housing 1. A lens assembly 2 is sleeved on the surface of the housing 1. A focusing motor 3 is driven and connected to one end of the lens assembly 2. An image sensor 4 is installed at one end of the focusing motor 3. A circuit connection substrate 5 is installed on one side of the image sensor 4. A heat dissipation mechanism 7 is installed on one side of the circuit connection substrate 5. A sealing plate 8 is installed on the rear side of the housing 1. A through groove 9 is opened on the surface of the sealing plate 8. Fixing mechanisms 6 are installed on both sides of the housing 1. The heat dissipation mechanism 7 includes an adhesive sticker 74, which is adhesively connected to the rear side of the circuit connection substrate 5. One side of the adhesive sticker 74 is fixedly connected to a protective cover. The protective surface layer 70 has vertical grooves 73 evenly spaced at the bottom end. A handle 75 is fixedly connected to the bottom of the protective surface layer 70. A movable piece 71 is installed on the surface of the protective surface layer 70. A heat dissipation groove 79 is formed on the surface of the movable piece 71. A heat-conducting block 77 is fixedly connected to the surface of the movable piece 71. Auxiliary ventilation grooves 76 are formed on both sides of the movable piece 71. A compression spring 791 is fixedly connected to the bottom of the movable piece 71. Limit keys 72 are fixedly connected to both sides of the movable piece 71. The protective surface layer 70 is made of asbestos. Anti-slip textures are formed on both sides of the protective surface layer 70. Slots that match the limit keys 72 are formed on both sides of the protective surface layer 70.
[0025] Specifically, the adhesive 74 is directly adhered to the rear end of the circuit connection substrate 5, allowing the mechanism to be installed. Simultaneously, the compression spring 791 continuously presses inward, causing the movable piece 71 to contact the rear end of the phone, facilitating heat conduction. During the movement of the movable piece 71, the limit key 72 slides into the sliding groove inside the protective surface layer 70, ensuring the movable piece 71 moves vertically in a straight line. When the movable piece 71 is conducting heat transfer, the heat dissipation groove 79 facilitates the main heat dissipation of the movable piece 71. Furthermore, the auxiliary ventilation groove 76, located inside its side, allows for controlled heat dissipation from the inside of the movable piece 71. The vertical groove 73 facilitates heat dissipation within the movable piece 71. Simultaneously, the vertical groove 73 provides basic protection for the movable piece 71, preventing damage from external objects and improving heat dissipation efficiency. When not in use, the handle 75 can be pulled to move the entire mechanism outwards for disassembly. The movable piece 71 is made of artificial graphite, enhancing its thermal conductivity. The protective surface layer 70 is made of asbestos, preventing heat loss from the movable piece 71. When the movable piece 71 reaches its limit position, it is flush with the top of the protective surface layer 70, ensuring constant contact between the movable piece 71 and the circuit connection substrate 5.
[0026] Example 2
[0027] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism 6 includes a movable block 60 and a frame 64. The movable block 60 is fixedly connected to both sides of the outer shell 1. A spring 61 is fixedly connected to one side of the inner side of the movable block 60. The frame 64 is fixedly connected to both sides of the sealing plate 8. A toggle block 62 is fixedly connected to one end of the spring 61. A locking block 63 is fixedly connected to one end of the toggle block 62. A movable groove 65 is provided on one side of the movable block 60.
[0028] Specifically, when it is necessary to fix the outer shell 1 to the sealing plate 8, by pressing down the toggle block 62, the locking frames 64 on both sides of the sealing plate 8 are engaged into the interior of the locking block 63, thereby fixing the sealing plate 8 to the outer shell 1. When it is necessary to move the sealing plate 8, the toggle block 62 is moved, and the toggle block 62 is squeezed by the spring 61, which drives the locking block 63 to move backward, so that the locking block 63 disengages from the locking frame 64, thereby detaching the sealing plate 8 from the outer shell 1, achieving the function of convenient movement and disassembly.
[0029] The working principle of the heat dissipation mechanism for the dashcam camera module will be explained in detail below.
[0030] like Figure 1-4As shown, the adhesive 74 is directly adhered to the rear end of the circuit connection substrate 5, allowing the installation of this mechanism to be completed. Simultaneously, the compression spring 791 continuously compresses inward, driving the movable piece 71 to contact the rear end of the phone, facilitating heat conduction. During the movement of the movable piece 71, the limit key 72 slides into the sliding groove inside the protective surface layer 70, ensuring the movable piece 71 moves vertically in a straight line. When the movable piece 71 is conducting heat transfer, the heat dissipation groove 79 facilitates the main heat dissipation of the movable piece 71. Simultaneously, the auxiliary ventilation groove 76, located inside its side, allows control over the flow of heat through the interior of the movable piece 71, facilitating internal heat dissipation. Furthermore, the vertical groove 73 provides basic protection for the movable piece 71, preventing damage to its surface from external objects and improving heat dissipation efficiency. In this device, it is not necessary to use... When in use, the handle 75 can be pulled to move the entire mechanism outwards to complete the disassembly. The moving piece 71 is made of artificial graphite, which improves the heat conduction performance of the moving piece 71. The protective surface layer 70 is made of asbestos, which can prevent the temperature of the moving piece 71 from spreading outwards. When the moving piece 71 moves to its limit position, it is flush with the top of the protective surface layer 70, which can keep the moving piece 71 in contact with the circuit connection substrate 5. When it is necessary to fix the outer shell 1 and the sealing plate 8, the toggle block 62 is pressed down, and the locking frames 64 on both sides of the sealing plate 8 are engaged into the inside of the locking block 63, so that the locking block 63 is engaged into the inside of the locking frame 64, thereby fixing the sealing plate 8 and the outer shell 1. When it is necessary to move the sealing plate 8, the toggle block 62 is moved. The toggle block 62 is squeezed by the spring 61, which drives the locking block 63 to move backward, so that the locking block 63 is disengaged from the locking frame 64, thereby separating the sealing plate 8 from the outer shell 1, achieving the function of convenient movement and disassembly.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
