Description

Technical Field

[0001] The utility model relates to the technical field of camera devices, in particular to a camera device and a movable platform. Background Art

[0002] With the innovation of technology, camera devices such as cameras and video cameras have gradually entered daily life. Camera devices utilize the principle of lens imaging to achieve image formation, and record and transmit image signals through photosensitive chips and related circuits. For an infrared camera, its photosensitive part can receive signals transmitted by infrared radiation, enabling the camera to take pictures 24 hours a day regardless of day or night. However, due to insufficient light at night, it is still difficult to take clear pictures. For example, in-vehicle DMS (Driver Monitor System) for monitoring the driver's state and in-vehicle OMS (Occupancy Monitoring System) for monitoring the passenger's state in a vehicle both use camera devices to take pictures of the driver or passengers, and then monitor and analyze the states of the driver and passengers to control the vehicle machine to make corresponding interactions. When in scenarios such as at night or passing through a tunnel, the camera device is prone to failing to capture the current state of the driver or passengers.

[0003] Therefore, infrared supplementary lighting technology is added to many camera devices to illuminate and supplement light in the FOV (Field of view) area of the camera, so that the infrared camera can obtain clear and bright image information. However, since a camera lens is generally composed of multiple groups of lenses, the lens usually has a certain length. However, the size of the supplementary light lamp is usually very small. If the components for supplementary lighting (including the supplementary light lamp, photosensitive chip, etc.) are all integrated on a single main board, there will be a height difference between the light inlet of the lens and the supplementary light lamp, affecting the supplementary lighting effect of the supplementary light lamp. Therefore, in the prior art, the supplementary light lamp is usually separated to form a separate supplementary light lamp circuit board, and the supplementary light lamp circuit board is connected to the main board through a wire harness, so that the position of the supplementary light lamp can be adjusted by setting the position of the supplementary light lamp circuit board.

[0004] However, this design still has many defects:

[0005] 1. Usually, it is difficult for the irradiation range of a supplementary light to match the FOV of a camera. Since the FOV of a camera is usually rectangular while the irradiation range of a supplementary light is generally circular, in order to make the irradiation range of the supplementary light completely cover the FOV of the camera, a supplementary light with a larger irradiation range needs to be used to completely cover the FOV of the camera. However, for LEDs of the same series with the same power, the larger the irradiation range, the smaller the irradiation intensity per unit area. Therefore, for shooting the same object at the same angle and distance, the supplementary lighting effect that can be achieved by one supplementary light with a small irradiation range requires two to three supplementary lights with a large irradiation range to achieve the same effect.

[0006] 2. The large number, high power, and high thermal power consumption of supplementary lights result in the need to increase the size of the radiator, which in turn leads to a relatively large overall size of the camera, unable to meet the requirements of the customer's usage space and lightweight. The power consumption of a single commonly used supplementary light is about 2 - 5W, belonging to high-power LEDs, and a heat dissipation structure is required to dissipate heat from it. When the number of supplementary lights increases to two or three, the weight of the required radiator increases exponentially. Therefore, using multiple supplementary lights will cause the overall size of the imaging device to be relatively large. Especially when applied to the vehicle-mounted scenario, it is difficult to find an assembly position for the imaging device on the vehicle and it is difficult to integrate into the overall appearance of the vehicle, making it lack market competitiveness.

[0007] 3. Generally, the heat dissipation structure on the outer housing is integrated on the rear shell. If both the supplementary light circuit board and the main board use the heat dissipation structure on the rear shell for heat dissipation, the heat emitted by the supplementary light is likely to affect the normal operation of the sensors and other components on the main board. Moreover, the rear shell also needs to extend a structure to fit the supplementary light circuit board for heat dissipation (due to the problem of the lens length, the supplementary light circuit board cannot be on the same plane as the main board where the lens is set), resulting in problems such as difficult molding and low molding yield of the outer housing. At the same time, in order to use the heat dissipation structure on the rear shell to dissipate heat from the supplementary light circuit board, the main board also needs to make room for the area where the supplementary light circuit board is set, making the shape of the main board strange and the available area compressed, affecting the size and design of the main board. Summary of the Utility Model

[0008] Embodiments of the present utility model provide an imaging device and a movable platform to solve the above or other potential problems in the prior art.

[0009] According to one aspect of the present utility model, an imaging device is provided, including:

[0010] An outer housing;

[0011] A lens module, including a lens circuit board disposed in the outer housing and a lens assembly disposed on the lens circuit board;

[0012] A supplementary light module, including a supplementary light assembly;

[0013] The light distribution module is arranged inside the housing and on the light source path of the fill light, and is used to adjust the irradiation area of the fill light assembly to match the field of view angle of the lens assembly.

[0014] The imaging device of the present utility model is configured with a light distribution module, and thus can use the light distribution module to adjust the irradiation area of the fill light assembly. Through design, the light distribution module enables the finally irradiated area of the fill light to match the field of view angle of the lens assembly. When the irradiation area of the fill light matches the field of view angle of the lens assembly, while maintaining the irradiation intensity of the fill light, the number of fill lights used in the fill light assembly can be reduced, thereby reducing the heat generation of the overall device, and effectively reducing the volume of the overall device. At the same time, through the adjustment of the irradiation area of the fill light assembly by the light distribution module, it is possible to avoid modifying the structure of the housing, etc. in order to adjust the arrangement position of the fill light assembly, making the layout inside the overall imaging device more concise and compact.

[0015] In some embodiments, the light distribution module includes one or more of a reflecting mirror, a refracting mirror, and a total reflection lens.

[0016] Thus, by such a setting, one or more of the reflecting mirror, the refracting mirror, and the total reflection lens can be combined to adjust the light source path, the light output direction, etc. of the fill light assembly, so as to adjust the irradiation area of the fill light assembly.

[0017] In some embodiments, the fill light module further includes a fill light circuit board arranged inside the housing. The fill light assembly is arranged on the fill light circuit board, and the lens circuit board and the fill light circuit board are arranged on different sides inside the housing.

[0018] Thus, by arranging the fill light circuit board and the lens circuit board on different sides inside the housing, the heat generated by the fill light circuit board can be separated from the heat generated by the lens circuit board, thereby avoiding the influence of the heat emitted by the fill light on the normal operation of sensors or other devices on the main board. And by such a setting, the housing can dissipate heat from the fill light circuit board and the lens circuit board respectively by arranging heat dissipation structures on the corresponding two sides, improving the heat dissipation efficiency, reducing the molding difficulty of the housing. At the same time, it is also possible to avoid the lens circuit board from avoiding the area of the fill light circuit board, increasing the available area of the lens circuit board, reducing the area occupied by the lens circuit board, and improving the utilization rate of the overall internal space, making the volume of the overall imaging device smaller.

[0019] In some embodiments, the light distribution module is arranged on the fill light circuit board, and a first positioning component is arranged between the light distribution module and the fill light circuit board.

[0020] Thus, by such an arrangement, the light distribution module can be fixedly arranged on the fill light circuit board, so that the positional relationship between the fill light components on the fill light circuit board and the light distribution module can be relatively fixed, ensuring the performance of adjusting the irradiation area of the light distribution module on the fill light components.

[0021] In some embodiments, heat dissipation structures are provided on the sides of the outer housing where the lens circuit board and the fill light circuit board are arranged.

[0022] Thus, by such an arrangement, heat dissipation structures can be respectively arranged at the positions where the lens circuit board and the fill light circuit board are arranged on the outer housing, realizing the separation of the heat dissipation structures on the outer housing, avoiding the concentration of heat dissipation positions, and thus effectively improving the heat dissipation efficiency of the overall imaging device and avoiding the influence on the normal operation of sensors or other devices on the lens circuit board caused by heat dissipation concentration.

[0023] In some embodiments, the fill light circuit board is connected to the lens circuit board to supply power to the fill light circuit board.

[0024] Thus, by such an arrangement, a dedicated power supply module designed for the fill light circuit board can be eliminated, effectively improving the compactness between the modules in the imaging device and reducing the volume of the overall imaging device.

[0025] In some embodiments, a circuit board connector is provided between the fill light circuit board and the lens circuit board.

[0026] Thus, by such an arrangement, the fill light circuit board and the lens circuit board can be quickly plugged and connected through the circuit board connector, reducing the assembly difficulty and making the connection between the two mechanical, improving the installation efficiency.

[0027] In some embodiments, the outer housing includes a first housing and a second housing that can be assembled and separated from each other. The fill light circuit board is arranged on the first housing, and the lens circuit board is arranged on the second housing.

[0028] Thus, by such an arrangement, the installation position of the fill light circuit board on the outer housing can be completely separated from the installation position of the lens circuit board on the outer housing, thereby reducing the mutual interference of the heat generated during operation.

[0029] In some embodiments, a second positioning component for installing the fill light circuit board is provided on the first housing, and a third positioning component for installing the lens circuit board is provided on the second housing.

[0030] Thus, by such an arrangement, the installation position of the fill light circuit board on the first housing can be ensured by the second positioning component, and the installation position of the lens circuit board on the second housing can be ensured by the third positioning component. Therefore, when the first housing and the second housing are assembled with each other, the accuracy of the installation between the fill light circuit board and the lens circuit board can be ensured, and the installation efficiency can be improved.

[0031] In some embodiments, a lens is provided at the light-emitting position of the fill light component on the outer housing. An installation groove for installing the lens is provided on the outer housing, and a glue groove is provided on the installation groove.

[0032] Thus, by such an arrangement, when the lens is installed on the installation groove of the outer housing and installed with glue, the glue can be kept in the glue groove, avoiding overflow and affecting the appearance and performance.

[0033] According to another aspect of the present invention, a movable platform is provided, including the imaging device in any of the above embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0048] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0049] Figure 1 and Figure 2 Schematically shows the overall structural schematic of a camera device according to an embodiment of the present utility model. Referring to Figure 1 and Figure 2 as shown, the camera device of the present utility model includes a housing 10, a lens module disposed inside the housing 10, as well as a fill light module and a light distribution module 12. The housing 10 is a housing for protecting the internal components of the camera device. The lens module is mainly used for capturing image information. The fill light module is mainly used for filling light for the shooting of the lens assembly 5. The light distribution module 12 is used to adjust the irradiation area of the light emitted by the fill light module so as to adjust the irradiation area of the light emitted by the fill light module to match the FOV (field of view angle) when the lens module captures image information. For the fill light module and the light distribution module 12, they can be disposed inside the housing 10 together with the lens module, or can be disposed outside the housing 10. When the fill light module is disposed outside the housing 10, the fill light module can be disposed alone or integrated on other products, so that the fill light module and the lens module can be independently installed at different positions. For example, the lens module and the fill light module can be independently installed at different positions of a vehicle, or the lens module and the fill light module can be respectively integrated on other in-vehicle products. When the fill light module is disposed inside the housing 10, the irradiation position of the light emitted by the fill light module can be better controlled, ensuring the fill light effect of the fill light module. Therefore, in the following text, the embodiments in which the fill light module is disposed inside the housing 10 will be mainly used to further describe the products of the present utility model.

[0050] Specifically, the light distribution module 12 can specifically include one or a combination of a reflector, a refractor, and a total reflection lens 14. The specific combination needs to be considered and designed according to the actual situation. In the present utility model, the irradiation area of the light emitted by the supplementary light module is adjusted to match the FOV (field of view) when the lens module captures image information. It should be understood that the irradiation position, irradiation range, and irradiation intensity of the light emitted by the supplementary light module are adjusted and corresponding to the shape of the FOV when the lens module captures image information. When designing the light distribution lens of the light distribution module 12, the light distribution software can be imported according to the actual situation to design the curved surface of the light distribution lens by using the light distribution software. The curved surface of the formed light distribution lens is required to be smooth. In the use scenario where the lens senses infrared light for supplementary lighting, the formed light distribution lens also needs to have a very high reflectivity to infrared light to reduce the loss of infrared light due to diffuse reflection and increase the utilization rate of the light source. The light distribution module 12 can be specifically formed by processes such as die casting of metal, CNC (Computer Numerical Control), etc., or can be injection molded by plastic parts. After molding, the light distribution surface also needs to be surface treated by plating a metal or metal alloy film to increase the smoothness of the light distribution surface and the reflectivity to light. Exemplarily, referring to Figure 3 As shown, in this embodiment, specifically, the position at half of the maximum irradiation intensity in the irradiation area of the light emitted by the supplementary light module is adjusted to correspond to the shape of the FOV when the lens module captures image information, so that the two are as closely matched as possible, so that the irradiation intensity of the light of the supplementary light module within the FOV when the lens module captures image information is maintained at a high level to improve the supplementary lighting effect of the supplementary light module. It can be understood that in this embodiment, the position at half of the maximum irradiation intensity is used as a reference for adjustment, and in other embodiments, other irradiation intensity values can also be used as a reference for adjusting the irradiation area of the light emitted by the supplementary light module. At the same time, in the present utility model, the matching between the irradiation area of the light emitted by the supplementary light module (such as Figure 3 the rectangular frame area in) and the FOV (field of view) when the lens module captures image information should not be understood as the ranges being exactly the same. It only needs to make the area ranges of the two as close as possible, or the overlap degree of the two areas is not less than a preset threshold to be considered as a match between the two. The preset threshold of this overlap degree can be set to 70%, 80%, 85%, or 90%, etc., to meet the supplementary lighting requirements as much as possible. Through such a design, the supplementary lighting effect that originally required two infrared supplementary lights with an irradiation area angle of 50° to irradiate at a 50° angle can now be achieved with only one infrared supplementary light, and there will be no blind spots and uneven brightness problems.

[0051] The lens module includes a lens circuit board 7 and a lens assembly 5. The lens circuit board 7 is arranged inside the outer housing 10, and the lens assembly 5 is arranged on the lens circuit board 7. It can be understood that the lens assembly 5 may include one or more lenses, and may also include structures such as a lens bracket 6 for mounting the lens. Other components, such as sensors, may also be provided on the lens circuit board 7, which can be designed according to the actual usage of the overall imaging device and will not be listed one by one here. The fill light module includes a fill light assembly 13, and the fill light assembly 13 may include one or more fill lights. The number of fill lights does not correspond to the number of lenses and can be designed according to the actual situation. Since the present utility model uses a light distribution module 12 to adjust the irradiation area of the light of the fill light assembly 13, in the present utility model, the fill light assembly 13 can be directly arranged on the lens circuit board 7, or a fill light circuit board 3 for supplying power and configuring the circuit for the fill light assembly 13 can be separately provided. It should be noted that for the lens assembly 5 in the present utility model, the photosensitive chip used can be an infrared chip, a visible light chip, or a photosensitive chip with multiple modes (infrared and visible light), and thus the fill light assembly 13 can adjust the type of the specifically set fill light according to the photosensitive chip used by the lens assembly 5.

[0052] Exemplarily, referring to Figure 7 shown, in Figure 7 the embodiment shown, the fill light of the fill light assembly 13 is set to one and is arranged on the lens circuit board 7. The light distribution module 12 can be set to a total reflection lens 14, and the light exit position of the total reflection lens 14 is set at a position consistent with the height of the lens assembly 5, so as to be able to adjust the light exit position of the fill light assembly 13 through the structure of the light distribution module 12, avoiding the adjustment of the setting position of the fill light assembly 13. At the same time, through the design of the structure of the total reflection lens 14, the light of the fill light incident into the total reflection lens 14 can be reflected and refracted and then emitted, so as to realize the adjustment of the irradiation area of the finally emitted light. Specifically, the parameters of the total reflection lens 14 used in this embodiment need to be adjusted according to factors such as the actual lens module, the parameters of the fill light assembly 13, and the setting position of the fill light assembly 13. The design method of the total reflection lens 14 can be designed with reference to the relevant descriptions in the prior art. For example, a light distribution software can be used to model and design the curvature of the reflector to control the light propagation direction, and this part of the content will not be elaborated here. According to Figure 7 the embodiment shown, it can be understood that when the fill light module is separately provided with a fill light circuit board 3 for setting the fill light assembly 13, a certain interval can be left between the fill light circuit board 3 and the lens circuit board 7. At this time, only the structure of the total reflection lens 14 needs to be adjusted to reduce its length.

[0053] In some other embodiments where the fill light module is independently provided with a fill light circuit board 3 for setting the fill light assembly 13, the fill light circuit board 3 can be set not to be parallel to the lens circuit board 7, and can be set to be respectively disposed on different sides within the outer housing 10 from the lens circuit board 7, so that the heat dissipated by the fill light circuit board 3 and the heat dissipated by the lens circuit board 7 are not concentrated on the same side of the outer housing 10, thereby effectively reducing the degree of heat dissipation concentration of the overall imaging device, and also avoiding the influence of the heat dissipated by the fill light circuit board 3 on the normal operation of the components on the lens circuit board 7. Exemplarily, referring to Figure 2 as shown, in Figure 2 the illustrated embodiment, the outer housing 10 is generally set in a cubic shape. At this time, the surface of the outer housing 10 where the end for shooting on the lens assembly 5 is located is called the front surface, the opposite surface is the back surface, and the remaining surfaces are the side surfaces. The lens circuit board 7 can be disposed on the inner side surface of the back surface of the outer housing 10, while the fill light circuit board 3 can be set to be perpendicular to the lens circuit board 7 and disposed on the inner side surface of the side surface of the outer housing 10, thereby avoiding the concentration of heat dissipation between the two circuit boards and greatly reducing the occurrence of the sensor thermal noise interference problem. At this time, since the fill light circuit board 3 is disposed on the inner side surface of the side surface of the outer housing 10, the initial light irradiation direction of the fill light assembly 13 disposed on the fill light circuit board 3 cannot be the same as the orientation of the lens assembly 5. Therefore, it is necessary to design the light distribution module 12 to adjust the final light irradiation direction and irradiation area of the fill light assembly 13 to meet the usage requirements of the imaging device. Specifically, in this embodiment, the light distribution module 12 can be constituted by a reflecting mirror. It can be understood that for an imaging device with the outer housing 10 set in other shapes, the relative positional relationship between the fill light circuit board 3 and the lens circuit board 7 can also be set not to be perpendicular to each other, as long as the fill light circuit board 3 and the lens circuit board 7 are disposed on different sides within the outer housing 10.

[0054] Exemplarily, referring to Figure 4 as shown, Figure 4Schematically shows the structure of the light distribution module 12 formed by a reflecting mirror in the imaging device of the present utility model. Specifically, the structure of the reflecting mirror forming the light distribution module 12 includes three groups of reflecting mirror groups that form different angles with the fill light circuit board 3. The three groups of reflecting mirror groups are arranged adjacent to each other in sequence, and for each group of reflecting mirror groups, as the distance from the fill light circuit board 3 increases, the included angle between it and the fill light circuit board 3 gradually decreases. Each group of reflecting mirror groups contains two symmetrically arranged reflecting mirrors, and the reflecting mirror can be a planar reflecting mirror, or a convex or concave reflecting mirror. Among them, in the light distribution module 12, parameters such as the included angle between the three groups of reflecting mirror groups and the fill light circuit board 3, the included angle between the two reflecting mirrors in a single group of reflecting mirror groups, and the shape and style of the reflecting mirror can be designed according to parameters such as the parameters of the actually used fill light component 13, the installation position of the fill light component 13, and the installation position of the fill light circuit board 3. They are not fixed, but need to be designed according to the actual application scenario. Refer to Figure 5 As shown, the finally formed light distribution module 12 can refract the light emitted by the fill light component 13 so that it is irradiated on the front of the outer housing 10, and its irradiation area corresponds to the FOV of the lens assembly 5.

[0055] Among them, on the front of the outer housing 10, at the position for irradiating the light of the fill light component 13, a lens 1 can be provided. The lens 1 can be set as an infrared-transmitting lens to provide supplementary light for the lens assembly 5 using an infrared-sensitive chip. The lens 1 can also be set as other lenses, and can be specifically designed according to the parameters of the lens assembly 5. In some possible implementation manners, refer to Figure 6 As shown, an installation groove 2-1 for installing the lens 1 can be provided on the front of the outer housing 10, so that the lens 1 will not protrude after installation, to ensure its performance and avoid affecting the appearance. In addition, a glue groove 2-2 can be provided on the installation groove 2-1. The glue groove 2-2 is used to accommodate excess glue. Then, when the lens 1 is installed and fixed on the installation groove 2-1 using glue, the excess glue can flow into the glue groove 2-2, avoiding glue overflow, which may affect the performance of the lens 1 and the overall appearance.

[0056] In some possible embodiments, the light distribution module 12 can be specifically arranged on the fill light circuit board 3. By relatively fixing the positions between the light distribution module 12 and the fill light circuit board 3, and also relatively fixing the positions between the fill light component 13 and the fill light circuit board 3, the relative positions between the light distribution module 12 and the fill light component 13 of the fill light module can be fixed, so as to ensure the accuracy of adjusting the irradiation area of the light from the light distribution module 12 on the fill light component 13. Among them, the installation between the light distribution module 12 and the fill light circuit board 3 can be a detachable connection installation method, such as connecting with the fill light circuit board 3 through a buckle or a screw 9, or a fixed connection installation method, such as fixing on the fill light circuit board 3 through welding, glue, etc. At the same time, in order to improve the accuracy of the installation position when the light distribution module 12 is installed on the fill light circuit board 3, a first positioning component can be arranged between the light distribution module 12 and the fill light circuit board 3. Refer to Figure 2 As shown, the first positioning component can be specifically implemented by using the structure of positioning posts and positioning holes. For example, positioning holes are arranged on the fill light circuit board 3, and a fixing shell for fixing the mirror group is arranged on the light distribution module 12, and corresponding positioning posts are arranged on the fixing shell. Thus, through the cooperation between the positioning posts and the positioning holes, the light distribution module 12 can be accurately installed at the corresponding position on the fill light circuit board 3. At the same time, the installation between the lens bracket 6 of the lens assembly 5 and the lens circuit board 7 can also be positioned and installed by using the method of positioning holes and positioning posts, so that its installation can be more accurate and the positions of the two can be better matched.

[0057] In order to improve the heat dissipation performance of the outer shell 10, a heat dissipation structure 15 can be designed on the outer shell 10. For the embodiment in which both the fill light module and the lens module are arranged on the same side inside the outer shell 10 (generally the inner side of the back surface of the outer shell 10), the heat dissipation structure 15 can be centrally arranged at the back position of the outer shell 10. Specifically, refer to Figure 1 As shown, the heat dissipation structure 15 can be a conventional structure such as heat dissipation fins, heat dissipation sheets, heat dissipation openings, etc., and the present utility model does not limit this. For the embodiment in which the fill light circuit board 3 and the lens circuit board 7 are arranged on different sides inside the outer shell 10, the heat dissipation structure 15 can be respectively arranged on the outer sides of the corresponding surfaces of the outer shell 10, so as to dissipate heat for the fill light circuit board 3 and the lens circuit board 7 respectively.

[0058] In some possible embodiments, the outer housing 10 may include a first housing 2 and a second housing 8 that can be assembled and separated from each other, and the fill light circuit board 3 is disposed on the first housing 2, and the lens circuit board 7 is disposed on the second housing 8. Such an arrangement can further separate the heat dissipated by the fill light circuit board 3 from the heat dissipated by the lens circuit board 7, thereby further alleviating the problem of concentrated heat generation of the overall imaging device. Specifically, one of the separated first housing 2 and second housing 8 includes the front surface of the outer housing 10, and the other includes the back surface of the outer housing 10. Taking the first housing 2 including the front surface of the outer housing 10 and the second housing 8 including the back surface of the outer housing 10 as an example, further, the first housing 2 includes at least one side surface of the outer housing 10 for disposing the fill light circuit board 3 in addition to including the front surface of the outer housing 10, and the second housing 8 includes the remaining side surfaces on the outer housing 10 and the back surface of the outer housing 10. Exemplarily, referring to Figure 2 as shown in Figure 2 the embodiment shown, the first housing 2 includes the front surface of the outer housing 10, and Figure 2 one side surface perpendicular to the Y-axis and far away in the Y-axis direction on the outer housing 10, and the second housing 8 includes the remaining surfaces of the outer housing 10. The fill light circuit board 3 is mounted on the inner side surface of the side surface of the first housing 2, and the lens circuit board 7 is mounted on the inner side surface of the back surface of the second housing 8. The mounting manner between the fill light circuit board 3 and the first housing 2, and the mounting manner between the lens circuit board 7 and the second housing 8 can be mounted by a detachable connection manner fixed by screws 9. Of course, other methods such as snap connection and plug connection can also be used for mounting, which will not be listed one by one here.

[0059] In some possible embodiments, the fill light circuit board 3 is connected to the lens circuit board 7, and thus the lens circuit board 7 can be used to supply power to the fill light circuit board 3. Specifically, referring to Figure 2 as shown, the connection between the fill light circuit board 3 and the lens circuit board 7 can be made by a circuit board connector 4. The circuit board connection includes a female end 4-1 of a straight plug connector and a male end 4-2 of a straight plug connector. Then, by respectively disposing the two on the fill light circuit board 3 and the lens circuit board 7, the fill light circuit board 3 and the lens circuit board 7 can be mechanically mounted and connected, so as to reduce the assembly difficulty. Compared with the connection manner between the fill light circuit board 3 and the lens circuit board 7 in the prior art, since the present utility model can only provide one fill light, the power supply required for the fill light circuit board 3 can be reduced, and thus the power connector for connecting to the fill light circuit board 3 on the lens circuit board 7 can be omitted, and the connection wire harness between the lens circuit board 7 and the fill light circuit board 3 can also be omitted, which can effectively improve the utilization rate of the lens circuit board 7 and reduce the volume of the overall imaging device.

[0060] In order to further improve the light filling effect of the fill light module on the lens module in the camera device of the present utility model, the first housing 2 may be provided with a second positioning component for installing the fill light circuit board 3, and the second housing 8 may be provided with a third positioning component for installing the lens circuit board 7. Thus, by positioning the lens circuit board 7 and the fill light circuit board 3, the light filling effect of the fill light module on the lens module can be ensured. Among them, the second positioning component and the third positioning component are the same as the first positioning component, and can be implemented by using the structure of positioning posts and positioning holes, or can also be implemented by other structures. Exemplarily, the second positioning component may be set to position and install the fill light circuit board 3 on the first housing 2 by means of connecting with screws 9 and screw holes. Similarly, the third positioning component may also be set to position and install the lens circuit board 7 on the second housing 8 by means of connecting with screws 9 and screw holes. Additionally, referring to Figure 2 as shown, in Figure 2 the shown embodiment, the second positioning component can also be connected and positioned by opening positioning holes on the first housing 2 and using the positioning posts on the light distribution module 12 that penetrate the positioning holes on the fill light circuit board 3, so that the positioning posts on the light distribution module 12 can be connected and positioned with both the fill light circuit board 3 and the first housing 2 at the same time, thereby ensuring the accuracy of the position where the fill light circuit board 3 is installed on the first housing 2, and also being able to ensure the accuracy of the position where the light distribution module 12 is installed on the first housing 2. At the same time, continuing to refer to Figure 2 as shown, in Figure 2 the shown embodiment, the third positioning member can be set in the same way as the second positioning member, that is, by opening positioning holes on the second housing 8 and using the positioning posts of the lens bracket 6 that penetrate the positioning holes on the lens circuit board 7 for connection and positioning, so that the positioning posts on the lens bracket 6 can be connected and positioned with both the lens circuit board 7 and the second housing 8 at the same time, thereby ensuring the accuracy of the position where the lens assembly 5 is installed on the second housing 8, and also being able to ensure the accuracy of the position where the lens assembly 5 is installed on the lens circuit board 7.

[0061] In addition, a coaxial connector 11 may be provided on the lens circuit board 7. The coaxial connector 11 is used for electrical connection with other devices. The coaxial connector 11 extends out of the second housing 8. A through hole for the coaxial connector 11 to pass through is provided on the second housing 8. The size of the through hole can be as close as possible to the size of the coaxial connector 11, so that a small-gap design is formed between the coaxial connector 11 and the through hole, thereby improving the concentricity between the coaxial connector 11 and the through hole on the second housing 8 during installation, and being able to play a role in positioning the lens circuit board 7. The function of the electrical connection of the coaxial connector 11 can also be replaced by other structures, such as other forms of connectors or wire harnesses, or directly integrated into other devices (such as vehicle electrical appliances), so that electrical connection can be achieved without a wire harness. Furthermore, the installation of each component in the camera device of the present utility model within the outer housing 10 can be made more precise, thereby ensuring the light supplement effect of the light supplement lamp module on the lens module.

[0062] The camera device of the present utility model is configured with a light distribution module 12, and thus can use the light distribution module 12 to adjust the irradiation area of the light supplement lamp assembly 13. Through design, the light distribution module 12 enables the finally irradiated area of the light supplement lamp to match the field of view angle of the lens assembly 5. When the irradiation area of the light supplement lamp matches the field of view angle of the lens assembly 5, while maintaining the irradiation intensity of the light supplement, the number of light supplement lamps used in the light supplement lamp assembly 13 can be reduced, thereby reducing the heat generation of the overall device and effectively reducing the volume of the overall device. At the same time, through the adjustment of the irradiation area of the light supplement lamp assembly 13 by the light distribution module 12, it is possible to avoid modifying the structure of the outer housing 10 in order to adjust the arrangement position of the light supplement lamp assembly 13, making the layout inside the overall camera device more concise and compact. By arranging the light supplement lamp circuit board 3 and the lens circuit board 7 on different sides within the outer housing 10, the heat generated by the light supplement lamp circuit board 3 can be separated from the heat generated by the lens circuit board 7, thereby avoiding the influence of the heat emitted by the light supplement lamp on the normal operation of sensors or other devices on the main board. And by setting it in this way, the outer housing 10 can be provided with heat dissipation structures 15 on two corresponding sides to respectively dissipate heat from the light supplement lamp circuit board 3 and the lens circuit board 7, improving the heat dissipation efficiency and reducing the molding difficulty of the outer housing 10. At the same time, it is also possible to eliminate the need for the lens circuit board 7 to avoid the area of the light supplement lamp circuit board 3, increase the available area of the lens circuit board 7, reduce the area occupied by the lens circuit board 7, improve the utilization rate of the overall internal space, and make the volume of the overall camera device smaller.

[0063] The embodiment of the present application also provides a movable platform, including any one of the camera devices described above.

[0064] Among them, the movable platform can be a vehicle, a robot, a drone, a ship, etc. The imaging device can be installed inside or outside the movable platform. For example, it can be installed on the front windshield of the vehicle, inside the cockpit, on the front of the vehicle, on the rearview mirror, etc. The imaging device can be used to capture images of the surrounding environment or the interior of the movable platform.

[0065] Those skilled in the art should be able to understand that for a movable platform equipped with an imaging device, it has the same beneficial effects as the above-mentioned imaging device. For example, by configuring a light distribution module, it is possible to adjust the irradiation area of the supplementary light lamp assembly using the light distribution module. Through design, the light distribution module enables the irradiation area finally emitted by the supplementary light lamp to match the field of view angle of the lens assembly. When the irradiation area of the supplementary light lamp matches the field of view angle of the lens assembly, it is possible to reduce the number of supplementary light lamps used in the supplementary light lamp assembly while maintaining the irradiation intensity of the supplementary light, thereby reducing the heat generation of the overall device and effectively reducing the volume of the overall device. At the same time, by adjusting the irradiation area of the supplementary light lamp assembly through the light distribution module, it is possible to avoid modifying the structure of the outer casing, etc. to adjust the arrangement position of the supplementary light lamp assembly, making the overall layout inside the imaging device more concise and compact, which is beneficial to improving the overall layout effect of the movable platform. When the movable platform is a vehicle and the imaging device is installed on the front windshield or inside the cockpit of the vehicle, a smaller-sized imaging device can reduce the occupation of the driver's visible area, meet the supplementary light requirements, facilitate obtaining higher-quality images, and improve the image recognition efficiency of the movable platform.
