[0043] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0044] Reference will be made below to Figures 1-8 Describe a camera grating assembly 10 according to an embodiment of the present invention, including: at least two stacked grating components 11, and the light transmission path 12 of each grating component 11 can be adjusted. It can be understood that during the use of the camera grating assembly 10, light is adapted to flow along the light channel 14, and when the light passes through the grating component 11, it is adapted to be adjusted by the grating component 11 so that the light can be integrated through the light transmission path 12 of each grating component 11, so that the light can flow along the light channel 14 for subsequent circulation and finally act on the camera to perform image light sensing. Exemplarily, a plurality of light channels 14 may be arranged along the optical path, arranged on both sides of the grating component 11, and adapted to adjust the light transmission amount flowing through the light channel 14 through the adjustable light transmission path 12 of the grating component 11.

[0045] It should be noted that during the use of in-vehicle cameras, since the vehicle needs to drive in different environments, the aperture of the camera needs to be adjusted in different light environments so that the imaging effect of the camera can meet the use requirements. However, in environments with relatively poor light effects such as at night, the brightness and clarity of the camera screen are relatively low, affecting the use of the camera and thus affecting the driving experience of the user when driving the vehicle.

[0046] According to the camera grating assembly 10 of the embodiments of the present utility model, during the use of the camera grating assembly 10, the light passing diameter size of the grating assembly 11 can be adjusted according to the environmental conditions, so as to increase the light input amount in the camera, making the camera grating assembly 10 have a higher light input amount during use, and improving the use performance of the camera grating assembly 10.

[0047] In some embodiments, the centers of each light passing diameter 12 are all on the same straight line. It should be noted that light is suitable for being transmitted through the light passing diameter 12, and by making the centers of each light passing diameter 12 on the same straight line, during the process of light being suitable for being transmitted through the light passing diameter 12, the light loss is small, making the use performance of the camera grating assembly 10 relatively high.

[0048] In some embodiments, each grating assembly 10 includes at least two gratings 400, and an adjustable light passing diameter 12 is formed between the at least two gratings 400. It can be understood that each grating assembly 11 includes at least two gratings 400 to form a light passing diameter 12 between the two gratings 400, and the relative position between the two gratings 400 is adjusted to realize the adjustment of the light passing diameter 12, so as to realize the adjustment of the light input amount of the grating assembly 11, thereby enabling the use performance of the camera grating assembly 10 to meet the user's needs.

[0049] In some specific embodiments, the setting directions of the gratings 400 in any two grating assemblies 11 are different. That is to say, the setting directions of the gratings 400 in the two grating assemblies 11 are different, so that during the use of the grating assembly 11, the relative positions between the gratings 400 in different grating assemblies 11 can be adjusted respectively to realize the adjustment of the light passing diameter 12, enabling the light input amount of the camera grating assembly 10 to be adjusted according to the environment, so that the camera grating assembly 10 also has a relatively high light input amount in the night environment to meet the use requirements, and making the camera grating assembly 10 have higher use performance. At the same time, the setting directions of the gratings 400 in any two grating assemblies 11 are different, so that when any two grating assemblies 11 are adjusted, it is suitable to adjust the gratings 400 in the two grating assemblies 11 respectively to realize the adjustment of the light passing diameter 12, making the adjustment process of the camera grating assembly 10 simpler and having higher adjustment accuracy.

[0050] In some embodiments, each grating assembly 11 further includes an arc segment 13, the arc segment 13 is arranged outside the light passing diameter 12, and there are a plurality of arc segments 13 spaced circumferentially. When the gratings 400 move to form the minimum light passing diameter, the arc segment 13 moves to the center to form a small aperture.

[0051] That is to say, each grating component 11 is also adapted to include an arc segment 13. The arc segment 13 can be correspondingly arranged outside the light transmission path 12, and the arc segment 13 can be adjusted according to the adjustment of the light transmission path 12. When the grating 400 moves to form the minimum light transmission path 12, the arc segment 13 moves to the center to form a small aperture. In this way, in the camera grating assembly 10, the current usage of the light transmission path 12 can be judged according to the position of the arc segment 13 to realize the adjustment of the light incident amount, making the use process of the camera grating assembly 10 simpler and more reliable.

[0052] In some embodiments, the camera grating assembly 10 includes: a first grating component 100 and a second grating component 200. Both the first grating component 100 and the second grating component 200 include: a carrier 300, at least two gratings 400 arranged oppositely, and a driving member 500. An installation portion 301 is provided on the carrier 300; the gratings 400 are correspondingly arranged in the installation portion 301; the driving member 500 is arranged in the carrier 300, and the driving member 500 is arranged oppositely to the gratings 400. That is to say, the structures of the first grating component 100 and the second grating component 200 are set to be the same, so as to facilitate production and reduce costs. At the same time, the assembly processes of the first grating component 100 and the second grating component 200 can also be simplified, and the assembly efficiency can be improved.

[0053] Specifically, both the first grating component 100 and the second grating component 200 include: a carrier 300, two gratings 400 arranged oppositely, and a driving member 500. The carrier 300 is adapted to provide a position for the arrangement of the gratings 400, so that the gratings 400 can be arranged to appropriate positions to realize the adjustment and limitation of the light transmission path. Driving members 500 are correspondingly arranged on both sides of the gratings 400. The driving members 500 are adapted to provide a driving effect to drive the gratings 400 to move, so as to adjust the positions of the two oppositely arranged gratings 400, so that the light transmission path formed between the two gratings 400 can be adjusted, so that the size setting of the light transmission path can meet the light requirements of different environments, making the use of the camera grating assembly 10 have high applicability.

[0054] Therefore, a camera grating assembly 10 is adapted to be constructed in the camera. The camera grating assembly 10 includes a first grating component 100 and a second grating component 200, so that the camera grating assembly 10 can adjust the first grating component 100 and the second grating component 200 for use according to environmental requirements, so that the use performance of the camera grating assembly 10 can meet various environmental conditions, making the use of the camera grating assembly 10 meet the use requirements of the camera in different environments, so that the camera in different environments has high imaging performance, and the picture brightness and clarity are high to improve the driving experience of the user driving the vehicle.

[0055] In some specific embodiments, a first light path 101 is provided on the first grating assembly 100, and a second light path 201 is provided on the second grating assembly 200. The first light path 101 and the second light path 201 are in the same straight line, so that when light enters the camera grating assembly 10 for transmission, it is adapted to be transmitted after passing through the first light path 101 and the second light path 201. Therefore, in different environmental conditions, the light paths of the first grating assembly 100 and the second grating assembly 200 can be adjusted according to requirements, so that the light transmitted to the camera later can meet the usage requirements, so that the usage performance and usage experience of the camera can meet the user's needs, and the driving experience of the vehicle can be improved.

[0056] According to the camera grating assembly 10 of the embodiment of the present invention, since the light paths of the first grating assembly 100 and the second grating assembly 200 can be adjusted, the usage performance of the camera grating assembly 10 can be adjusted according to the control breathing invariance method, so that the usage performance of the camera grating assembly 10 can meet the usage requirements of the camera in different environments, so that the camera has a high usage performance to meet the user's use, especially in the case of insufficient environmental light at night, etc., so as to improve the driving experience of the user driving the vehicle.

[0057] In some embodiments, the setting direction of the grating 400 of the first grating assembly 100 is perpendicular to the setting direction of the grating 400 of the second grating assembly 200. In this way, by making the setting direction of the grating 400 of the first grating assembly 100 perpendicular to the setting direction of the grating 400 of the second grating assembly 200, the first grating assembly 100 and the second grating assembly 200 can jointly limit the light path, so that the light entering the subsequent camera can be restricted as required, so that the usage performance of the camera grating assembly 10 can be better adjusted, so as to improve the usage performance of the camera grating assembly 10, so that the performance of the camera grating assembly 10 can better meet the subsequent usage requirements.

[0058] In some embodiments, the mounting portion 301 is a circular mounting portion 301. It can be understood that by setting the mounting portion 301 as a circular mounting portion 301, the circular mounting portion 301 can facilitate the assembly and setting of the grating 400. While simplifying the assembly process, it can also improve the structural reliability of the setting, so as to improve the usage performance of the camera grating assembly 10. At the same time, when the subsequent driving member 500 adjusts the grating 400, the driving member 500 can more reliably transmit the driving action to the grating 400 to drive the grating 400 to move according to the usage requirements, so that the camera grating assembly 10 can be used as required.

[0059] In some embodiments, the driving member 500 includes: a coil 510. On the carrier 300, there is also provided a coil mounting position. The coil 510 is disposed on the coil mounting position, and the coil 510 is disposed opposite to the grating 400 and magnetically adsorbed. When the coil 510 is energized, the coil 510 and the grating 400 attract each other to increase the diameter size of the light passing path. It can be understood that the coil mounting position can provide a position for the arrangement of the coil 510, so that the coil 510 can be arranged in the coil mounting position according to requirements, making the arrangement of the coil 510 more reliable. Thus, during the use of the coil 510, it is suitable to enable or disable the coil 510 according to control, so that the coil 510 can generate a corresponding magnetic field according to the design, drive the grating 400 to move according to the design use, correspondingly adjust the size of the first light passing path 101 or the second light passing path 201, thereby realizing the adjustment of the use performance of the camera grating assembly 10, enabling the use of the camera grating assembly 10 to meet the requirements, and improving the use satisfaction of the camera grating assembly 10.

[0060] In some specific embodiments, the coil 510 includes a plurality of turns arranged at intervals. The same ends of the plurality of turns form a power-on end, and the other end of each turn is provided with a power-off end. That is to say, the coil 510 is suitable to include a plurality of turns. During the use of the coil 510, it is suitable to adjust the magnitude of the current flowing through the coil 510 and the number of turns of the coil 510 through which the current passes, so as to adjust the magnetic field generated by the coil 510, enabling the magnetic field generated by the coil 510 to meet the use requirements for the magnetic movement of the grating 400, making the light passing through the camera grating assembly 10 meet the use requirements of the camera, and thus improving the use reliability of the camera in different environmental conditions.

[0061] In some embodiments, the camera grating assembly 10 further includes: an elastic member 600. On the carrier 300, there is also provided an elastic mounting position. The elastic member 600 is fixedly connected to the elastic mounting position, and the elastic member 600 is arranged at an interval from the coil 510. The elastic end of the elastic member 600 abuts against the grating 400. When the coil 510 is powered off, the elastic member 600 elastically drives the grating 400 to move closer to the center to reduce the diameter size of the light passing path.

[0062] That is to say, during the process of using the driving member 500 to drive the grating 400 to move, the grating 400 will also correspondingly drive the elastic member 600 to be compressed. When the coil 510 is powered off, the magnetic field generated by the coil 510 disappears, and the elastic action on the elastic member 600 is suitable to drive the grating 400 to reset, especially drive the grating 400 to move in the central direction, so as to reduce the diameter size of the light passing path, enabling the setting of the light passing path to meet the use requirements and making the use performance of the camera grating assembly 10 more in line with the use requirements.

[0063] In some specific embodiments, the elastic member 600 is a spring piece. In this way, setting the elastic member 600 as a spring piece can not only reduce the production cost of the elastic member 600, but also enable the elastic member 600 to have sufficient elastic effect to meet the subsequent driving and resetting of the grating 400. At the same time, the spring piece also has a high number of usage times, so as to reduce the usage cost of the camera grating assembly 10 and improve the service life.

[0064] In some embodiments, the driving member 500 further includes: a stepper motor, which is disposed on the carrier 300, and the output end of the stepper motor is connected to the grating 400. When the stepper motor is powered on, the stepper motor drives the grating 400 to move to adjust the diameter size of the light passing path. That is to say, a stepper motor can also be used as the driving member 500. The stepper motor can provide an accurate driving effect according to the control to convey the grating 400 to a suitable position for use. At the same time, the stepper motor can also drive the grating 400 to reset, so that the structure of the camera grating assembly 10 using the stepper motor is simpler, the structure of the camera grating assembly 10 is more reliable, and the usage performance and service life of the camera grating assembly 10 are improved.

[0065] In some embodiments, the camera grating assembly 10 further includes: a controller, which is communicatively connected to the driving member 500 to control the grating 400 to move to adjust the diameter of the light passing path. It can be understood that when the camera detects that the light in the environment is insufficient or the user actively needs to increase the clarity and brightness of the picture, it is suitable to control the camera grating assembly 10 to increase the light passing path; and when the camera detects that the light in the environment is sufficient or the user actively needs to increase the field of view, it is suitable to control the camera grating assembly 10 to reduce the light passing path. At this time, during the use of the camera, it is suitable to transmit the control instruction to the controller to drive the controller to adjust the light passing path size of the camera grating assembly 10 according to the instruction, so that the light passing through the camera grating assembly 10 can meet the use requirements, so that the use of the camera can meet the requirements and improve the user's use experience of the camera.

[0066] The camera according to an embodiment of the present invention includes: the camera grating assembly 10 as above.

[0067] It should be noted that during the use process, the environment needs to be detected. For example, start the camera, then capture the current environmental image, perform algorithmic perception analysis on the captured image, input and judge the structure. When it is detected that the environmental light is insufficient, it is suitable to send a control signal to increase the light passing path of the camera grating assembly 10, and detect the performance of the adjusted camera, such as capturing the image again and performing analysis until the analyzed image can meet the use requirements.

[0068] In this way, since the camera grating assembly 10 as shown above is provided inside the camera, and since the light passing diameter of the grating assembly 11 can be adjusted so that the performance of the camera grating assembly 10 can be controlled and adjusted, the performance of the camera grating assembly 10 can meet the usage requirements of the camera in different environments, enabling the camera to have high performance to meet the user's needs, thereby enhancing the driving experience of the user when driving the vehicle.

[0069] The vehicle according to an embodiment of the present invention includes: the camera as above. In this way, since the camera inside the vehicle can adjust the camera grating assembly 10 according to environmental changes, the camera can provide good performance in different environments to meet the usage requirements, thereby improving the driving experience of the vehicle.

[0070] The other components and operations of the vehicle according to an embodiment of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
