[0034] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below, in which only the parts related to the embodiment of the present invention are shown.

[0035] Example:

[0036] like Figure 1-4 As shown, the utility model provides a driving recorder with a heat dissipation structure, including: a fixed part 1, a rotating part 2, a shooting structure 3 and a heat dissipation structure 4; the shooting structure 3 and the heat dissipation structure 4 are both arranged in the rotating part 2, and the rotating part 2 is rotatably connected to the fixed part 1; the shooting structure 3 includes a main control board 31 and a camera module 32, and the camera module 32 is connected to the main control board 31; the heat dissipation structure 4 includes a first heat dissipation member 41 and a second heat dissipation member 42, the first heat dissipation member 41 is arranged on one side of the main control board 31 and is located on the side of the camera module 32, and the second heat dissipation member 42 is arranged on the other side of the main control board 31.

[0037] Specifically, if Figure 1-4 As shown, a portion of the rotating portion 2 is disposed within the fixed portion 1 and is rotatably connected to the fixed portion 1. The fixed portion 1 is fixed to the vehicle, and the rotating portion 2 can rotate angularly relative to the fixed portion 1. The imaging structure 3 and the heat dissipation structure 4 are both disposed within the rotating portion 2 and can rotate with the rotating portion 2. The imaging structure 3 disposed within the rotating portion 2 can be adjusted to meet different shooting angle requirements. It should be noted that the rotating portion 2 and the fixed portion 1 are circular in shape.

[0038] like Figure 2-3 As shown, the camera structure 3 and the heat dissipation structure 4 are both disposed within the rotating portion 2 and protected by the rotating portion 2. The camera structure 3 comprises a main control board 31 and a camera module 32. The camera module 32 is mounted on one side of the main control board 31 via a plug-in interface. The main control board 31, located on one side of the camera module 32, also houses multiple chips and components that enable the camera module 32 to function properly. Under the control of the main control board 31, the camera module 32 can capture images of the vehicle's exterior. During operation, the chips on the control board 31 generate a significant amount of heat. The heat dissipation structure 4 is designed to dissipate this heat to ensure proper functioning of the main control board 31.

[0039] like Figure 2-3 As shown, the heat dissipation structure 4 includes a first heat sink 41 and a second heat sink 42. The first heat sink 41 is disposed on one side of the main control board 31 and is located next to the camera module 32. It is used to dissipate heat generated by the chips on the main control board 31 during operation. The second heat sink 42 is disposed on the other side of the main control board 31 and is also used to dissipate heat generated by the chips on the main control board 31 during operation.

[0040] It should be noted that if Figure 2 As shown, the first heat sink 41 in this embodiment is configured as a cylindrical structure, specifically a semicircular cylindrical structure. The cylindrical structure has a cavity inside that can accommodate components required by the main control board 31 (such as the capacitor module 33), saving space while increasing the heat dissipation area. One end of the flat surface of the first heat sink 41 is fixedly connected to the main control board 31 via a thermally conductive interface material.

[0041] like Figure 3As shown, the side where the second heat sink 42 is connected to the main control board 31 may be a flat structure, a boss structure or a groove structure. The second heat sink 42 may be an aluminum extruded heat sink with fins to improve its heat dissipation performance. It should be noted that the second heat sink 42 is connected to the main control board 31 through a thermal interface material. Among them, the thermal interface material may be a thermally conductive silicone pad 44. The thermally conductive silicone pad 44 has good thermal conductivity and can quickly conduct the heat generated by the heat source (the chip on the main control board 31) to the first heat sink 41 and the second heat sink 42. The heat is dissipated by the first heat sink 41 and the second heat sink 42 to reduce heat accumulation, ensure the normal operation of the driving recorder, and increase the service life of the driving recorder to a certain extent. It should be noted that the first heat sink 41 and the second heat sink 42 can be sprayed with a nano-carbon coating to enhance the radiation heat dissipation performance.

[0042] As an optional implementation, Figure 2-3 As shown, the rotating part 2 includes a first shell 21 and a second shell 22, which are arranged opposite to each other and can be detachably connected; the first shell 21 and the second shell 22 are connected to form a accommodating cavity, and the shooting structure 3 and the heat dissipation structure 4 are both arranged in the accommodating cavity.

[0043] Specifically, the rotating unit 2 includes a first shell 21 and a second shell 22, and the first shell 21 and the second shell 22 are detachable structures. Specifically, the first shell 21 and the second shell 22 are detachably connected by a snap, which facilitates installation and disassembly. After the first shell 21 and the second shell 22 are connected, they form a storage cavity, in which the imaging structure 3 and the heat dissipation structure 4 are disposed. The main control board 31 is disposed within the second shell 22, with the second heat dissipation element 42 positioned toward the second shell 22; the first heat dissipation element 41 is positioned toward the first shell 21.

[0044] In this embodiment, if Figure 2-3 As shown, the first heat sink 41 and the second heat sink 42 are respectively disposed on different surfaces of the main control board 31, dissipating heat from both the front and back surfaces of the main control board 31. In this embodiment, the first heat sink 41, the second heat sink 42, the camera module, and the main control board 31 are all disposed within the accommodating cavity, resulting in a compact structure that saves internal space and reduces the overall size of the device. In this embodiment, the first heat sink 41 and the second heat sink 42 may be aluminum extruded heat sinks.

[0045] It should be noted that the material of the first shell 21 and the second shell 22 can be plastic. Plastic has a certain thermal conductivity and will not affect the heat dissipation of the first heat sink 41 and the second heat sink 42 .

[0046] As an optional implementation, Figure 4As shown, the outer ring of one end of the first shell 21 and the second shell 22 connected to the fixed part 1 is provided with a convex portion 23, and the inner ring of the fixed part 1 is provided with a concave portion 11. After the first shell 21 and the second shell 22 are connected, they are rotatably connected to the fixed part 1 through the convex portion 23 and the concave portion 11.

[0047] Specifically, the rotating portion 2 formed by connecting the first shell 21 and the second shell 22 will be rotatably connected to the fixed portion 1. Figure 4 As shown, the outer ring of the rotating portion 2 at the end where it connects to the fixed portion 1 is provided with multiple protrusions 23 over 360°, and the inner ring of the fixed portion 1 is provided with multiple recesses 11 over 360°. These protrusions 23 and recesses 11 connect the rotating portion 2 and the fixed portion 1. The multiple recesses 11 on the outer ring of the rotating portion 2 are evenly distributed, as are the multiple recesses 11 on the inner ring of the fixed portion 1. The number of protrusions 23 and recesses 11 is equal. This allows for adjustment of the rotating portion 2 and the fixed portion 1 to a specific angle. This specific angle is determined by the number of protrusions 23 and recesses 11. For smaller angles, the number of protrusions 23 and recesses 11 needs to be increased accordingly. For larger angles, the number of protrusions 23 and recesses 11 can be reduced.

[0048] Furthermore, in this embodiment, the material of the rotating part 2 can be plastic, which has certain deformation properties. Therefore, the fixed part 1 and the rotating part 2 can achieve a static stable and tight connection, and can also achieve dynamic rotation.

[0049] As an optional implementation, Figure 2 As shown, an auxiliary seat 24 is protruding from the first housing 21. The position of the auxiliary seat 24 corresponds to the position of the camera module 32, and the center line of the auxiliary seat 24 coincides with the center line of the camera head in the camera module 32, so that the camera module 32 can pass through the auxiliary seat 24 to take pictures. Specifically, since the camera module 32 is equipped with a camera lens and its overall structure protrudes outward, the auxiliary seat 24 is provided to ensure normal shooting of the camera module 32 and to protect the camera module 32, thereby ensuring normal shooting of the camera module 32.

[0050] As an optional implementation, Figure 2-3As shown, a side cover 25 is provided at one end of the rotating portion 2, and an interface hole 26 and a card slot hole 27 are provided on the side cover 25; a power interface 34 and a card slot 35 are provided on the main control board 31, and the power interface 34 and the card slot 35 are respectively arranged to correspond to the interface hole 26 and the card slot 27 on the side cover 25; the power interface 34 is used to connect to an external power cord, and the card slot 35 is used to install a memory card. Specifically, the side cover 25 can be provided at an end close to the fixed portion 1 or at an end away from the fixed portion 1. When the side cover 25 is provided at an end close to the fixed portion 1, the two ends of the fixed portion 1 are connected, which facilitates the placement of the rotating portion 2, the connection of the power interface 34 to an external power source, and the placement of the memory card. When the side cover 25 is provided at an end away from the fixed portion 1, the end of the fixed portion 1 away from the rotating portion 2 can be directly provided as a closed structure. In this embodiment, the side cover 25 can optionally be provided at an end close to the fixed portion 1. Since both the power interface 34 and the latch slot 35 are disposed within the rotating portion 2, the power interface 34 and the latch slot 35 rotate with the rotating portion 2 regardless of the angle of rotation, without affecting the proper use of the power interface 34 and the latch slot 35. It should be noted that the side cover 25 can be fixedly connected to the rotating portion 2 using buckles or screws, but this is not specifically limited in this embodiment.

[0051] As an optional implementation, Figure 2 As shown, a connector 12 protrudes from the fixing portion 1, through which the dashcam is fixedly connected to the vehicle. Specifically, the connector 12 protrudes from the fixing portion 1 to facilitate installation of the dashcam on the vehicle. Double-sided adhesive tape 13 is provided at the bottom of the connector 12 for bonding. The dashcam is attached to the vehicle using the double-sided adhesive tape 13, such as to the front windshield, rear windshield, or other desired locations on the vehicle.

[0052] As an optional implementation, Figure 3 As shown, the driving recorder also includes a voice module 5, which is fixedly arranged on the inner side of the first shell 21 and is connected to the main control board 31, and is used to collect environmental sounds, output the collected environmental sounds, or emit prompt sounds. The voice module 5 in this embodiment is connected to the main control board 31, and is powered and controlled by the main control board 31. The voice module 5 includes a sound receiving module and a speaker module. After the driving recorder is started, the camera module 32 will capture environmental images, and the sound receiving module will also capture and record the sounds at the same time. The subsequent speaker module can play the collected sounds. It has various functions and will not be described in detail in this embodiment.

[0053] As an optional embodiment, a GPS module for positioning is provided on the main control board 31. Specifically, the function of GPS is to locate the location of the vehicle equipped with the driving recorder, and at the same time, it can also record the driving trajectory to prevent the vehicle from being stolen.

[0054] In this embodiment, the rotating portion 2 and the fixed portion 1 are rotatably connected, allowing the rotating portion 2 to rotate, enabling adjustment of the angle of the camera structure 3. Furthermore, the camera structure 3, the first heat sink 41, and the second heat sink 42 are all located within the rotating portion 2, resulting in a compact and space-saving structure. The first and second heat sinks 41, 42 are located on either side of the main control board 31, dissipating heat generated by the chips on the main control board 31 during operation. This ensures uniform heat dissipation and reduces heat accumulation.

[0055] The embodiment is only a special example and does not indicate that the present invention is implemented in such a way.

[0056] The above description is merely a preferred embodiment of the present invention. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
