Description

Technical Field

[0001] This application relates to the field of automotive accessories technology, and in particular to a dashcam. Background Technology

[0002] A dashcam is a device used to record images and other relevant information while a vehicle is in motion. After installation, a dashcam can objectively record events that occur during vehicle operation, providing strong evidence for determining liability in traffic accidents.

[0003] In addition to video recording, dashcams can also be equipped with more functional components to record more information such as sound or provide more interactive options. However, with the diversification of functions, the size of dashcams will also increase, obstructing more of the field of vision after installation and becoming less aesthetically pleasing. Utility Model Content

[0004] This application provides a dashcam, comprising: a main housing having a first receiving cavity; a main control circuit board having a main control component; a camera circuit board having a camera component, the camera circuit board and the main control circuit board being stacked in the first receiving cavity along a first direction; and a power storage device electrically connected to the camera circuit board through the main control component and stacked relative to the camera circuit board and the main control circuit board.

[0005] In the technical solution of this application embodiment, since a camera circuit board and a main control circuit board are provided, and the camera component and the main control component are respectively mounted on their respective circuit boards, each circuit board needs to support fewer components compared to having them all mounted on a single circuit board. This reduces the size of each circuit board. Furthermore, because the camera circuit board and the main control circuit board are stacked, each circuit board is only stacked in the thickness direction, ultimately forming a more compact and regular whole. This helps improve the space utilization rate within the first accommodating cavity, thereby helping to reduce the size of the main body shell. Since the energy storage component is stacked relative to the camera circuit board and the main control circuit board, it can utilize the space between the camera circuit board and the main control circuit board, or only be stacked in the thickness direction. The required additional space is small or even non-existent, further improving space utilization. This allows the dashcam to provide more functions while reducing its own size. In addition, the camera component and the main control component are mounted on different circuit boards, which helps installers identify them and facilitates later maintenance.

[0006] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0018] The following explanation is based on the accompanying drawings.

[0019] This application provides a dashcam, such as... Figures 1 to 4 and Figure 8 As shown, it includes: a main body shell 10, the main body shell 10 having a first receiving cavity; a main control circuit board 20, the main control circuit board 20 having a main control component 30; a camera circuit board 40, the camera circuit board 40 having a camera component 50, the camera circuit board 40 and the main control circuit board 20 being stacked in the first receiving cavity along a first direction; and a power storage device 70, the power storage device 70 being electrically connected to the camera circuit board 40 through the main control component 30, and being stacked relative to the camera circuit board 40 and the main control circuit board 20.

[0020] The dashcam includes a main housing 10, a main control circuit board 20, a main control component 30, a camera circuit board 40, a camera component 50, and a power storage device 70. The main housing 10 forms a first receiving cavity, in which the main control circuit board 20, the camera circuit board 40, and the power storage device 70 are all housed. At least a portion of the main control component 30 and at least a portion of the camera component 50 are also housed within the first receiving cavity. The camera component 50 is electrically connected to the camera circuit board 40. The main control component 30 is electrically connected to the main control circuit board 20, and through the main control circuit board 20, is electrically connected to the camera circuit board 40 and the power storage device 70, respectively.

[0021] The camera assembly 50 is mounted on the camera circuit board 40 and is used to acquire images. The main control assembly 30 is mounted on the main control circuit board 20. The main control assembly 30 is electrically connected to the camera assembly 50 through the main control circuit board 20 and the camera circuit board 40. It is used to acquire images and also to control the operation of the camera assembly 50.

[0022] Furthermore, the dashcam also includes functional components, which are components with functions such as audio recording. These functional components are mounted on the main control circuit board 20, and can be positioned between the main control circuit board 20 and the camera circuit board 40, utilizing the space between them. The functional components are electrically connected to the main control component 30, used to transmit messages to the main control component 30, and are controlled by the main control component 30 to operate.

[0023] The main control circuit board 20 and the camera circuit board 40 are stacked along a first direction. This stacking arrangement means that the extension directions of the main control circuit board 20 and the camera circuit board 40 are parallel to each other, and within the same projection plane perpendicular to the first direction, the projections of the main control circuit board 20 and the camera circuit board 40 at least partially overlap. The first direction is perpendicular to the extension direction of the main control circuit board 20; in other words, the first direction is parallel to the thickness direction of the main control circuit board 20.

[0024] The energy storage device 70 is capable of storing and supplying electrical energy. The energy storage device 70 is electrically connected to the main control component 30 to supply power to the main control component 30. The camera component 50 obtains electrical energy through the main control component 30.

[0025] For example, the energy storage device 70 may be a battery, a supercapacitor, etc.

[0026] In some embodiments, the energy storage device 70 is a battery, and the camera circuit board 40 and the battery are located on opposite sides of the main control circuit board 20 in the first direction. Compared with supercapacitors, batteries have a higher energy density; for the same weight or volume, batteries can store more energy and provide more power. Furthermore, batteries have a lower self-discharge rate, can store energy for a longer period, and have a longer battery life.

[0027] In other embodiments, the battery may be located between the main control circuit board 20 and the camera circuit board 40 to utilize the space between the main control circuit board 20 and the camera circuit board 40.

[0028] Within the same projection plane perpendicular to the first direction, the projection of the energy storage device 70 at least partially overlaps with the projections of the main control circuit board 20 and the camera circuit board 40. In other words, the energy storage device 70 is stacked relative to the main control circuit board 20 and the camera circuit board 40.

[0029] To facilitate a compact arrangement of the energy storage device 70 and the circuit boards, the shape of the energy storage device 70 can be similar to that of the circuit boards, forming a plate shape, such as a square battery. The extending direction of the square battery is parallel to the extending direction of the main control circuit board 20, and the camera circuit board 40, the main control circuit board 20, and the square battery are stacked along the first direction.

[0030] Furthermore, within the same projection plane perpendicular to the first direction, the projections of the camera circuit board 40 and the main control circuit board 20 can completely overlap, making the main control circuit board 20 and the camera circuit board 40 form a unified whole with regular edges, which helps to save space in the first receiving cavity. Also, within the same projection plane perpendicular to the first direction, the projection of the energy storage device 70 is located within the projection of the main control circuit board 20, making the energy storage device 70, the main control circuit board 20, and the camera circuit board 40 together form a unified whole with relatively regular edges, which helps to save space in the first receiving cavity.

[0031] In the technical solution of this application embodiment, since a camera circuit board 40 and a main control circuit board 20 are provided, and the camera component 50 and the main control component 30 are respectively disposed on the corresponding circuit boards, each circuit board needs to support fewer components compared to being centrally disposed on a single circuit board, thereby reducing the required size of each circuit board. Furthermore, since the camera circuit board 40 and the main control circuit board 20 are stacked, each circuit board is only stacked in the thickness direction, ultimately forming a more compact and regular whole, which helps to improve the space utilization rate within the first accommodating cavity, thereby helping to reduce the size of the main body shell 10. Since the energy storage component 70 is stacked relative to the camera circuit board 40 and the main control circuit board 20, the energy storage component 70 can utilize the space between the camera circuit board 40 and the main control circuit board 20, or only be stacked in the thickness direction, requiring less or even no additional space, further improving space utilization. This allows the dashcam to provide more functions while reducing its own size. In addition, the camera component 50 and the main control component 30 are disposed on different circuit boards, which helps installers identify them and facilitates later maintenance.

[0032] In some embodiments, such as Figure 5As shown, the dashcam also includes a photovoltaic panel 120, which is electrically connected to a battery and is used to convert solar energy into electrical energy and store it in the battery.

[0033] The photovoltaic panel 120 is used to receive solar energy and convert it into electrical energy. The photovoltaic panel 120 can be electrically connected to the battery through the main control component 30 to continuously charge the battery.

[0034] To allow the photovoltaic panel 120 to receive more sunlight, it can be mounted on the surface of the main casing facing upwards along the direction of gravity, with the photovoltaic panel 120 exposed to the outside. Alternatively, the photovoltaic panel 120 can be externally connected, positioned near a car window, and electrically connected to a battery via wires.

[0035] Because it is equipped with a photovoltaic panel 120, the dashcam can generate its own electricity, which helps to improve the dashcam's battery life and enhance its reliability.

[0036] In some embodiments, the dashcam also includes a charging circuit board 130 housed in a first receiving cavity. The charging circuit board 130 is electrically connected to the main control component 30. On the same projection plane perpendicular to the first direction, the projection of the charging circuit board 130 overlaps with the projection of the main control circuit board 20, the projection of the camera circuit board 40, and the projection of the energy storage device 70.

[0037] Thus, the camera circuit board 40, the main control circuit board 20, and the energy storage device 70 utilize the space on one side surface of the charging circuit board 130, and the charging circuit board 130 can utilize the space superimposed in the thickness direction of the camera circuit board 40, the main control circuit board 20, and the energy storage device 70, so that the charging circuit board 130, the camera circuit board 40, the main control circuit board 20, and the energy storage device 70 together form a relatively regular whole, which is conducive to improving the compactness of the layout and improving the space utilization rate.

[0038] In some embodiments, such as Figures 5 to 8 As shown, the dashcam also includes a base housing 110, which is rotatably connected to the main body housing 10 and located on one side of the main body housing 10 along a second direction. The first direction is perpendicular to the second direction. The side of the base housing 110 away from the main body housing 10 is used to connect with an external vehicle.

[0039] The base shell 110 is rotatably connected to the main shell 10. The base shell 110 may have one rotational degree of freedom, for example, the base shell 110 may rotate about a first axis or about a second axis; the base may also have two rotational degrees of freedom, for example, the base may be able to rotate about a first axis and a second axis. The base shell 110 rotates relative to the main shell 10 to adjust the relative angle and position of the two.

[0040] The first axis is parallel to the second direction, and the first axis and the second axis intersect. For example, the first axis and the second axis are perpendicular.

[0041] like Figure 8 As shown, the charging circuit board 130 may also be disposed in the second cavity instead of the first cavity.

[0042] The charging circuit board 130 is equipped with a charging plug 131, part of which protrudes from the housing 110 for electrical connection to an external power source. The charging plug 131 is electrically connected to the energy storage device 70 via the main control component 30 to charge the energy storage device.

[0043] Therefore, the energy storage device 70 can obtain electrical energy through an external power source.

[0044] Furthermore, the dashcam can be equipped with both a charging circuit board 130 and a photovoltaic panel 120, which helps the dashcam obtain sufficient power and ensures its battery life.

[0045] In some embodiments, the photovoltaic panel 120 and the charging circuit board 130 are stacked in a direction perpendicular to the first direction.

[0046] In some embodiments, such as Figures 5 to 8 As shown, the dashcam also includes a pivot 100 and a damping component. The pivot 100 is located between the seat housing 110 and the main body housing 10. The pivot 100 has a first axis and a second axis. The pivot 100 is rotatably connected to the main body housing 10 along the first axis and rotatably connected to the seat housing 110 along the second axis. A damping component is provided between the pivot 100 and the main body housing 10 to generate rotational damping when the pivot 100 rotates with the main body housing 10 along the first axis. A damping component is also provided between the pivot 100 and the seat housing 110 to generate rotational damping when the pivot 100 rotates with the seat housing 110 along the second axis. After the relative position and angle of the seat housing 110 and the main body housing 10 are adjusted, the damping component can maintain the relative position and angle of the two.

[0047] Rotational damping refers to the ability to provide resistance or slow down rotation during operation, 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 smooth and even transition from one angle to another, providing a comfortable user experience. Secondly, rotational damping can precisely hold the user at the desired angle. Thirdly, rotational damping absorbs kinetic energy during rotation, reducing vibration and noise, making rotation quieter and smoother.

[0048] 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.

[0049] In a specific embodiment, such as Figure 8 As shown, the rotating shaft 100 includes a turntable 101 and a rotating shaft 102. The turntable 101 is rotatably connected to the main body shell 10 and is capable of rotating about a first axis. The rotating shaft 102 extends parallel to a second axis and passes through the turntable 101. The base shell 110 is capable of rotating about the second axis via the rotating shaft 102. The rotating shaft 102 can be configured to rotate about the second axis relative to the turntable 101, or it can be configured to be fixed to the turntable 101 while the base shell 110 rotates about the rotating shaft 102.

[0050] The rotating shaft 102 can be located at the center of the turntable 101 or at an off-center point of the turntable 101.

[0051] This application does not impose any special limitations on the shape of the damping element. For example, the damping element may be ring-shaped or strip-shaped.

[0052] In one specific embodiment, the damping element is a rubber ring. The rubber ring is sleeved around the periphery of the turntable 101, abutting against both the turntable 101 and the main body shell 10, providing rotational damping when the turntable 101 rotates relative to the main body shell 10. The base shell 110 is connected to a rotating shaft 102, which is rotatably connected to the turntable 101. The rubber ring is sleeved on the rotating shaft 102, abutting against both the rotating shaft 102 and the turntable 101, providing rotational damping when the rotating shaft 102 rotates relative to the turntable 101.

[0053] Therefore, the turntable 101 can rotate 360 ​​degrees relative to the main body shell 10, and the main body shell 10 can also have a large adjustment angle through the pivot 102, reducing the blind spots of the camera 51 and meeting shooting requirements. Moreover, the structure is simple, and the cost of the damping component is lower than that of a mechanical pivot.

[0054] The base housing 110 is located on one side of the main housing 10 along the second direction. The side of the base housing 110 opposite to the main housing 10 is used to connect to an external vehicle. A suction cup, adhesive layer, etc., can be provided on the side of the base housing 110 away from the main housing 10 to fix the dashcam inside the vehicle. In actual use, the base housing 110 is fixed to the window of the external vehicle, and the main housing 10 is rotated to face the camera 51 towards the front of the vehicle for recording road conditions. Users can also rotate the main housing 10 to point the camera 51 at other locations for recording, depending on their needs.

[0055] Since the pivot 100 can rotate relative to the main body shell 10 around the first and second axes, the position and angle of the main body shell 10 relative to the base shell 110 can be adjusted to achieve omnidirectional adjustment. Because a damping element generates rotational damping when the pivot 100 rotates, after adjusting the relative orientation of the main body shell 10 and the base shell 110, the pivot can remain in the adjusted orientation, and the adjustment feel is also good.

[0056] In some embodiments, the base shell 110 has an adhesive part on the side opposite to the main body shell 10 for attaching the dashcam to the vehicle.

[0057] Therefore, the dashcam can be attached to the windshield of an external car via the adhesive part, and the adhesive part itself occupies little space, allowing the housing 110 to fit tightly against the glass with minimal obstruction to the user's view.

[0058] In some embodiments, such as Figure 5 As shown, the photovoltaic panel 120 is located on the side of the base shell 110 away from the main body shell 10.

[0059] The photovoltaic panel 120 is located on the side of the base shell 110 away from the main body shell 10. In other words, the photovoltaic panel 120 is located on the side of the base shell 110 that is used to connect with the outside vehicle. Thus, after installation, the photovoltaic panel 120 can face the outside vehicle's glass and easily obtain sufficient sunlight.

[0060] In some embodiments, such as Figure 8 and Figure 9 As shown, the dashcam also includes a mounting assembly 160 located in the first receiving cavity. The mounting assembly 160 includes: a first bracket 161 having a first side and a second side facing away from each other along a first direction, the first side being used to mount the main control circuit board 20; and a second bracket 162 disposed on the second side of the first bracket 161. The second bracket 162 and the first bracket 161 enclose a first receiving space, the first receiving space being used to accommodate the energy storage device 70.

[0061] Therefore, by using a single mounting component 160 to provide mounting and support for both the main control circuit board 20 and the energy storage device 70, the structure becomes more compact. Furthermore, the main control circuit board 20 and the energy storage device 70 are located on opposite sides of the first bracket 161, which separates the main control circuit board 20 and the energy storage device 70. This helps to reduce the mutual interference between the heat generated by the main control circuit board 20 and the heat generated by the energy storage device 70, thereby reducing the risk of overheating.

[0062] In some embodiments, such as Figure 9As shown, at least two snap-fit ​​grooves 161a are formed on the surface of the second side of the first bracket 161. The at least two snap-fit ​​grooves 161a are arranged at intervals along the third direction. The second bracket 162 is inserted into the corresponding snap-fit ​​grooves 161a on both sides along the third direction to achieve snap-fit ​​between the second bracket 162 and the first bracket 161. The third direction is approximately perpendicular to the first direction.

[0063] The camera assembly 50 includes a camera 51, which is disposed on the side of the camera circuit board 40 away from the main control circuit board 20 and protrudes relative to the camera circuit board 40.

[0064] When assembling the dashcam, the first bracket 161, the camera circuit board 40, and the main control circuit board 20 can be placed together in the first receiving cavity. The main body shell 10 has a hole on one side surface in the first direction for exposing the camera 51. Push the first bracket 161, the camera circuit board 40, and the main control circuit board 20 together toward the hole so that the camera 51 is exposed from the hole and enough space is left on the second side of the first bracket 161 to place the second bracket 162. The second bracket 162 enters the space and is plugged into the first bracket 161.

[0065] Thus, the second bracket 162 and the first bracket 161 can be detachably connected. Moreover, the snap-fit ​​groove 161a can position the second bracket 162. During the assembly process, the second bracket 162 can be snapped into the snap-fit ​​groove 161a along both sides of the second direction. The structure is simple and the operation is convenient.

[0066] In some embodiments, such as Figure 8 As shown, the main body shell 10 includes a cover 11 and a shell 12. One end of the shell 12 in the second direction has an opening that communicates with the first receiving cavity, and the cover 11 covers the opening. The dashcam also includes a connector 170. The second bracket 162 is provided with a first connecting part 163. The connector 170 passes through the cover 11 and is connected to the first connecting part 163. The first direction, the second direction, and the third direction are approximately perpendicular to each other.

[0067] The cover 11 and the shell 12 together form the main shell 10. The base shell is rotatably connected to the cover 11.

[0068] The number of first connecting parts 163 is at least one. The first connecting part 163 is located on at least one side of the second bracket 162 along the third direction. At least one first connecting part 163 may be provided on one side of the second bracket 162 along the third direction, or at least one first connecting part 163 may be provided on both sides of the second bracket 162 along the third direction.

[0069] The first connecting portion 163 has a connecting hole for the connector 170 to pass through. The connector 170 passes through the connecting hole of the cover 11 and the first connecting portion 163, so that the mounting assembly 160 can be fixed relative to the main body shell 10.

[0070] This application does not impose any special limitations on the specific structure of the connector 170. For example, the connector 170 may be a threaded pin, a self-tapping pin, etc.

[0071] In some embodiments, see also [link to previous document]. Figure 8 The main body shell 10 includes a cover 11 and a shell 12. One end of the shell 12 in the second direction has an opening that communicates with the first receiving cavity, and the cover 11 covers the opening. The vehicle recorder also includes a connector 170. The shell 12 is provided with a second connecting part, and the connector 170 passes through the cover 11 and is connected to the second connecting part.

[0072] The housing 12 has a first inner sidewall and a second inner sidewall opposite to each other in a first direction. The first inner sidewall is located on the side of the second bracket 162 opposite to the first bracket 161 in the first direction. The second inner sidewall has a hole for the camera 51 to pass through. The second connecting part can be disposed on the first inner sidewall or on the second inner sidewall.

[0073] The second connecting portion has a connecting hole for the connector 170 to pass through. The connector 170 passes through the connecting hole of the cover 11 and the second connecting portion, so that the cover 11 can be fixed relative to the housing 12. At this time, the connector 170 may not pass through the connecting hole of the first connecting portion 163, and the mounting assembly 160 is limited by the inner walls of the cover 11 and the housing 12.

[0074] The connector 170 can also pass through the cover 11, the first connecting part 163, and the second connecting part to fix the relative positions of the cover 11, the mounting component 160, and the housing 12. Specifically, when assembling the dashcam, the mounting component 160, the main control circuit board 20, the camera circuit board 40, the power storage component 70, etc., can be placed in the first receiving cavity, and the connecting holes of the first connecting part 163 and the second connecting part can be aligned. Then, the cover 11 is placed over the opening, and the connector 170 passes through the connecting holes of the cover 11, the first connecting part 163, and the second connecting part to complete the assembly of the dashcam.

[0075] Therefore, the connector 170 can not only fix the housing 12 and the cover 11, but also fix the second bracket 162 simultaneously. The structure of the three is relatively compact and occupies little space.

[0076] The number of second connecting parts can be one or more, but the number of second connecting parts must be the same as the number of connecting parts 170.

[0077] In one specific embodiment, the cross-section of the housing 12 perpendicular to the second direction is rectangular, and the second connecting portion is disposed at at least one corner of the housing 12.

[0078] In some embodiments, the second bracket 162 is smaller in size in the second direction than the first bracket 161 in the second direction, so that a heat dissipation gap is formed between the second bracket 162 and the cover 11.

[0079] Therefore, the heat of the energy storage device 70 located between the first support 161 and the second support 162 can be dissipated through the heat dissipation gap, which can improve the problem of the energy storage device 70 being too hot and affecting the charging and discharging efficiency.

[0080] In some embodiments, such as Figure 8 As shown, the cover 11 has a third connecting part 13 on the side facing the first receiving cavity. The third connecting part 13 extends toward the first receiving cavity and is disposed opposite to the first connecting part 163 in the second direction.

[0081] The third connecting part 13 has a channel extending in the second direction, which passes through both ends of the cover 11 in the second direction and is directly opposite to the connecting hole of the first connecting part 163. The connector 170 is guided by the channel and inserted into the connecting hole of the first connecting part 163.

[0082] In some embodiments, the cover 11 is provided with a third connecting portion 13 on the side facing the first receiving cavity. The third connecting portion 13 extends toward the first receiving cavity and is disposed opposite to the second connecting portion in a second direction.

[0083] The channel can also be aligned with the connection hole of the second connection part, and the connector 170 is guided by the channel to be inserted into the connection hole of the second connection part.

[0084] Furthermore, the third connecting part 13 can be disposed opposite to the first connecting part 163 and the second connecting part, so that the channel is aligned with the connecting hole of the first connecting part 163 and the connecting hole of the second connecting part.

[0085] Therefore, the third connecting part 13 can guide the insertion direction of the connector 170, allowing the connector 170 to be smoothly inserted into the connecting holes of the first connecting part 163 and / or the second connecting part, which helps to reduce assembly difficulty and improve assembly efficiency. Furthermore, the third connecting part 13 can wrap around and limit the connector 170, preventing it from shaking and making the connection between the cover 11, the housing 12, and the mounting assembly 160 more stable.

[0086] In some embodiments, such as Figures 2 to 4 As shown, the main control circuit board 20 and the camera circuit board 40 are stacked and separated from each other along the first direction.

[0087] Therefore, there is sufficient space between the main control circuit board 20 and the camera circuit board 40 to accommodate at least one of the main control component 30, the camera component 50, the energy storage component 70, and the functional components, and this is beneficial for heat dissipation of each circuit board and each component.

[0088] In some embodiments, such as Figure 4 As shown, the dashcam also includes a connection component 80, the two ends of which are detachably connected to the camera circuit board 40 and the main control circuit board 20, respectively.

[0089] This application does not impose any special limitations on the specific structure for implementing the detachable connection. For example, the detachable connection can be a magnetic fit connection, a threaded fit connection, an interference fit connection, etc.

[0090] Since the two ends of the connecting component 80 are detachably connected to the camera circuit board 40 and the main control circuit board 20 respectively, the distance between the camera circuit board 40 and the main control circuit board 20 can be adjusted by replacing the connecting component 80 with different lengths, so that the distance between the camera circuit board 40 and the main control circuit board 20 meets the installation space required by each component.

[0091] This application does not impose a special limitation on the number of connecting components 80. For example, the number of connecting components 80 is four, and the four connecting components 80 are respectively disposed at the four corners of the main control circuit board 20.

[0092] In some embodiments, the connecting assembly 80 includes a screw 86 and a nut. The screw 86 passes sequentially through the camera circuit board 40 and the main control circuit board 20. There are three nuts: two nuts are located between the camera circuit board 40 and the main control circuit board 20, respectively abutting against the camera circuit board 40 and the main control circuit board 20; and one nut is located on the side of the main control circuit board 20 away from the camera circuit board 40, abutting against the main control circuit board 20. The camera circuit board 40 is confined between the head of the screw 86 and the nut, and the main control circuit board 20 is confined between the two nuts.

[0093] In some embodiments, such as Figure 2 and Figure 4 As shown, the connecting assembly 80 includes a screw 86, a nut, and a spacer retaining sleeve 87. The screw 86 passes through the camera circuit board 40, the spacer retaining sleeve 87, the main control circuit board 20, and the nut in sequence.

[0094] Specifically, the spacer retaining cylinder 87 has a cavity extending through itself in a first direction. The screw 86 passes through the camera circuit board 40 and is inserted into the cavity of the spacer retaining cylinder 87, thus confining the camera circuit board 40 between the screw head and the spacer retaining cylinder 87. After passing through the cavity, the screw 86 passes through the main control circuit board 20. A nut is fitted onto the screw 86 from the side of the main control circuit board 20 away from the spacer retaining cylinder 87, thus confining the main control circuit board 20 between the spacer retaining cylinder 87 and the nut.

[0095] Therefore, by replacing the spacer cylinders 87 of different lengths, the spacing between the main control circuit board 20 and the camera circuit board 40 can be adjusted so that the spacing between the camera circuit board 40 and the main control circuit board 20 meets the installation space required by each component.

[0096] In some embodiments, such as Figure 3 As shown, the dashcam also includes a flexible printed circuit board connector 90, through which the main control circuit board 20 and the camera circuit board 40 are electrically connected.

[0097] Dashcams also include flexible printed circuit board (FPC) connectors. These connectors are relatively thin, flexible, and occupy little space, enabling high-density wiring in confined spaces.

[0098] In some embodiments, the dashcam also includes heat-conducting sheets, with heat-conducting sheets respectively provided on the main control circuit board 20 and the camera circuit board 40.

[0099] The dashcam also includes heat-conducting sheets. There can be two heat-conducting sheets, one on the main control circuit board 20 and the other on the camera circuit board 40. Alternatively, fewer heat-conducting sheets can be used, with only the camera circuit board 40 and the main control circuit board 20 on them; more can also be used. This application does not impose any special limitation on the number of heat-conducting sheets.

[0100] On the main control circuit board 20, a portion of the heat-conducting sheet contacts and adheres to the main control circuit board 20, while the other portion of the heat-conducting sheet is suspended and used to dissipate heat to the surrounding environment. On the camera circuit board 40, a portion of the heat-conducting sheet contacts and adheres to the camera circuit board 40, while the other portion of the heat-conducting sheet is suspended and used to dissipate heat to the surrounding environment.

[0101] Furthermore, the main control circuit board 20 has areas where heat is concentrated. These areas can be connected to the heat-conducting sheet using thermally conductive adhesive, or a thermally conductive path can be formed using thermally conductive adhesive to connect the areas where heat is concentrated to the heat-conducting sheet. In other words, the thermally conductive adhesive extends from the areas where heat is concentrated to the heat-conducting sheet. Similarly, the camera circuit board 40 also has areas where heat is concentrated. These areas can be connected to the heat-conducting sheet using thermally conductive adhesive, or a thermally conductive path can be formed using thermally conductive adhesive to connect the areas where heat is concentrated to the heat-conducting sheet.

[0102] Therefore, improving the heat dissipation of the main control circuit board 20 and the camera circuit board 40 helps to improve the reliability of the circuit boards.

[0103] In some embodiments, such as Figure 7 As shown, a through hole 10a is provided on one side of the main body shell 10. The first receiving cavity is connected to the outside through the through hole 10a. The heat-conducting sheet on the main control circuit board 20 extends from the main control circuit board 20 toward the direction close to the through hole 10a. The heat-conducting sheet on the camera circuit board 40 extends from the camera circuit board 40 toward the direction close to the through hole 10a.

[0104] In a direction perpendicular to the first direction, a through hole 10a is provided on one side wall of the main body shell 10, the through hole 10a penetrating the main body shell 10 and communicating with the first receiving cavity. For the heat-conducting sheet disposed on the main control circuit board 20, a portion is attached to the main control circuit board 20, and another portion extends from the main control circuit board 20 towards the through hole 10a. For the heat-conducting sheet disposed on the camera circuit board 40, a portion is attached to the camera circuit board 40, and another portion extends from the camera circuit board 40 towards the through hole 10a.

[0105] To reduce dust entering the first receiving cavity through the through-hole 10a, the through-hole 10a can be located on the side of the main body shell 10 facing the bottom along the direction of gravity. Furthermore, a dustproof mesh can also be installed at the through-hole 10a.

[0106] Therefore, the through hole 10a is connected to the outside, and the heat-conducting plate near the through hole 10a can dissipate heat to the outside through the through hole 10a, which helps to improve the heat dissipation effect.

[0107] In some embodiments, the dashcam also includes a microphone, which is located on the main control circuit board 20 near the through hole 10a.

[0108] The radio receiver is one of the functional components, and it is located on the main control circuit board 20, near the through hole 10a. This helps the radio receiver acquire clearer audio.

[0109] In some embodiments, the dashcam also includes a speaker located on the main control circuit board 20 near the through hole 10a, so that the sound can be transmitted without obstruction and the sound is clearer.

[0110] In some embodiments, such as Figure 3 As shown, the dashcam also includes an indicator light, a connector 62, and a storage unit 63, which are located between the main control circuit board 20 and the camera circuit board 40.

[0111] Indicator lights, connector 62, and storage unit 63 are all functional components.

[0112] The indicator light is mounted on the main control circuit board 20 and electrically connected to the main control component 30, with part of the indicator light protruding from the main body housing 10. The indicator light is located between the main control circuit board 20 and the camera circuit board 40 to utilize the space between the main control circuit board 20 and the camera circuit board 40, and then the light from the indicator light is guided to the main body housing 10 by a light-guiding material (such as light-guiding silicone).

[0113] The connector component 62 is mounted on the main control circuit board 20 and electrically connected to the main control assembly 30, with a portion of the connector component protruding from the main housing 10. The connector component is located between the main control circuit board 20 and the camera circuit board 40 to utilize the space between them.

[0114] The storage function 63 is disposed on the main control circuit board 20 and electrically connected to the main control component 30. The storage function 63 includes a memory card, which is detachably installed on the main control circuit board 20. The storage function 63 is located between the main control circuit board 20 and the camera circuit board 40 to utilize the space between the main control circuit board 20 and the camera circuit board 40.

[0115] Optionally, the dashcam also includes a button, which is electrically connected to the main control component 30, and the button is used at least to control the power supply.

[0116] Therefore, the indicator light, the port function 62 and the storage function 63 can make full use of the space between the main control circuit board 20 and the camera circuit board 40, making the overall structure more compact and occupying less space, which helps to reduce the size of the dashcam.

[0117] In some embodiments, see further reference. Figure 8 The housing 110 has a second receiving cavity, and the dashcam also includes a positioning antenna 140 housed in the second receiving cavity. The positioning antenna 140 is electrically connected to the main control component 30.

[0118] The dashcam also includes a positioning antenna 140 for receiving satellite signals. The positioning antenna 140 is housed in a second receiving cavity and is electrically connected to the main control component 30 located in a first receiving cavity.

[0119] This enables the dashcam to have a positioning function, and the positioning antenna 140 is located in an independent space relative to the main control component 30 and the camera component 50, keeping the positioning antenna 140 away from interference energy. The satellite signal in the surrounding space is relatively strong, which is conducive to the positioning antenna 140 responding to radio signals quickly and accurately.

[0120] In some embodiments, the dashcam also includes a positioning chip, which is disposed on the main control circuit board 20, and the positioning antenna 140 is electrically connected to the main control component 30 through the positioning chip.

[0121] Therefore, the positioning antenna 140 is separated from the positioning chip, keeping the positioning antenna 140 away from interference energy. The satellite signal in the surrounding space is relatively strong, which is conducive to the positioning antenna 140 responding to radio signals quickly and accurately.

[0122] In some embodiments, such as Figures 2 to 4 and Figure 8 As shown, the dashcam also includes a display screen 150 electrically connected to the main control component 30. The display screen 150, the main control circuit board 20 and the camera circuit board 40 are stacked along the first direction, and the display screen 150 is embedded in the main body shell 10.

[0123] The display screen 150 and the camera 51 are exposed from opposite sides of the main body shell 10 in the first direction. After installation, the camera 51 generally faces the front of the vehicle, and the display screen 150 faces the inside of the vehicle for easy viewing by the user.
