[0002] With the development of vehicle intelligence, more and more vehicle models are equipped with display screens in the cockpit. The existing in-vehicle display methods are mainly designed according to the needs of the driver, and it is difficult to take into account the experience of other passengers in the vehicle. In some vehicle models, although a camera can be used to capture the interior of the carriage to obtain the image information of the driver and the front passenger. Then, the orientation of the main control display screen is adjusted by detecting the human face according to the image information of the driver and the front passenger. However, the above solution requires an independent camera to be set in the cockpit, and the orientation of the main control display screen can only be adjusted according to the detection information of the driver and the front passenger, which not only increases the cost but also cannot adjust the rear screen. Therefore, a solution is needed to solve the above problems. Summary of the Invention

The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or a similar expression refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple. Additionally, in the embodiments of this application, terms such as "first" and "second" do not limit the quantity and order.

[0035] It should be noted that in this application, words such as "exemplary" or "for example" are used to give examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner. Terms such as "connection" and "coupling" related to the embodiments of this application should be understood in a broad sense. For example, it can refer to a direct physical connection or an indirect connection achieved through electronic devices, such as a connection achieved through resistors, inductors, capacitors, or other electronic devices.

[0036] The following provides a detailed description of this application in conjunction with the drawings and embodiments:

[0037] With the development of automotive intelligence, current intelligent vehicles increasingly focus on the experience of passengers and drivers. Among them, as Figure 1 shown, the cockpit 110 of the vehicle 100 generally includes a center console 111, front row seats 112, and rear row seats 113. A display screen 1111 is usually provided on the center console 111 of the cockpit 110. To improve the usage experience of the driver and the front passenger, many vehicles 100 are provided with a camera 114 for collecting the head image information of the occupants in the cockpit 110 in front of the front row seats 112 (including the driver's seat and the front passenger's seat). At the same time, sensors for detecting the occupancy status and posture of the occupants are also provided on the front row seats 112. The vehicle control system in the vehicle 100 ( Figure 1The occupant image information that can be obtained through the camera 114 (not shown in the figure) and the in-position status and posture of the occupant detected by the sensor are used to control the display screen 1111 of the center console 111 to rotate so that the display screen 1111 faces the driver or the co-pilot passenger, or to perform split-screen display through the display screen 1111. Among them, the above vehicle-mounted control system can be set on the center console 111 or at other positions of the vehicle. The embodiments of the present application do not make specific limitations on this. However, the above method requires an independent camera to be set at positions such as the A-pillar of the vehicle 100 (i.e., the connecting pillars on both sides of the front windshield of the cockpit for connecting the roof and the front left and right compartments) that are convenient for obtaining the head image information of the driver and the co-pilot. This not only increases the production cost but also increases the production process and wiring difficulty of the vehicle. In addition, the above solution can only be used to adjust the orientation of the display screen on the center console and cannot provide a good experience for the passengers in the back row of the driver or the co-pilot. To improve the riding experience of the rear passengers, in medium- and high-configured vehicles, electronic devices 115 including screens are also configured on the backs of the driver's seat and the co-pilot's seat. The electronic device 115 is usually set at the headrest of the front seat for the passengers sitting in the rear seat to play videos, watch TV, and play games for entertainment, etc. However, the electronic devices 115 currently configured on the backs of the driver's seat and the co-pilot's seat are generally fixed on the headrests of the seats, and the passengers need to keep their line of sight at the same level as the headrest during use, maintaining a fixed posture for a long time, resulting in a poor experience for the passengers. Although there are also some electronic devices configured on the backs of the driver's seat and the co-pilot's seat that can adjust the tilt angle through a bracket. However, it requires the passengers to manually adjust the tilt angle of the bracket according to the actual usage requirements, and the usage experience is poor.

[0038] In some embodiments, such as Figure 2As shown in the figure, the above vehicle-mounted control system 200 includes a body control module (BCM) 210, a front-row seat adjustment device 220, a rear-row seat adjustment device 230, and a camera 114. Among them, the front-row seat adjustment device 220 is used to adjust the front-to-back position of the front-row seat 112 in the cabin and the tilt angle of the seat back. The rear-row seat adjustment device 230 is used to adjust the front-to-back position of the rear-row seat 113 in the cabin and the tilt angle of the seat back. The above front-row seat adjustment device 220 and rear-row seat adjustment device 230 are both communicatively connected to the body control module 210. The body control module 210 can also control the front-row seat adjustment device 220 to adjust the front-to-back position of the front-row seat 112 in the cabin and the tilt angle of the seat back according to the occupant image information obtained by the camera 114. In some solutions, the above front-row seat adjustment device 220 and rear-row seat adjustment device 230 both include a drive motor and a microcontroller unit (MCU). Among them, the microcontroller can adjust the front-to-back position of the corresponding seat in the cabin and the tilt angle of the seat back by controlling the drive motor.

[0039] To solve this problem, as Figure 3As shown, an embodiment of the present application provides a bracket device 300, which is used to connect to a first seat. At the same time, the bracket device 300 is also used to place an electronic device 400, supply power to the electronic device 400, and communicatively connect the electronic device 400 to the vehicle control system 200. The bracket device 300 can adjust the pitch angle, the first seat can adjust its attitude, and the electronic device 400 includes a screen and a camera. Among them, the bracket device 300 may include a bracket base 310, a controller 320, a first motor 330, a transmission structure 340, and a placement part 350. The bracket base 310 is used to connect to the first seat. Among them, the bracket base 310 can be connected to the first seat in a detachable manner, and the structure of the bracket base 310 may not be specifically limited. The controller 320 and the first motor 330 can be arranged on the bracket base 310, and the rotating shaft of the first motor 330 is connected to the placement part 350 through the transmission structure 340. The placement part 350 can be used to place the electronic device 400, and a connection port 351 for connecting the electronic device 400 is provided on the placement part 350. The electronic device 400 can be powered through the connection port 351. In addition, the electronic device 400 can also be communicatively connected to the vehicle control system through the connection port 351. Among them, the above connection port 351 can be a universal serial bus (USB) interface. The USB interface can select various common interfaces, for example, Type-A interface, Type-C, etc., and the embodiment of the present application does not make specific limitations on this. Based on this, the above bracket device 300 can receive an attitude adjustment instruction of the screen generated by the electronic device 400 according to the occupant image information collected by the camera. The attitude adjustment instruction is used to indicate the pitch angle of the bracket device 300 or the attitude of the first seat. Then, the bracket device 300 can also send the attitude adjustment instruction to the vehicle control system 200. Among them, when there are only two rows of seats in the cockpit, the above first seat can be the driver's seat or the passenger seat. When there are more than three rows of seats in the cockpit, the above first seat is any row of seats except the last row of seats at the rear of the cockpit, and the bracket device 300 is provided on the backrest of the first seat.

[0040] In the above manner, when there is an occupant sitting on the second seat behind the first seat, the occupant image information can be collected through the camera of the electronic device 400, and an attitude adjustment instruction of the screen generated by the electronic device 400 according to the occupant image information can be obtained. The attitude adjustment instruction can be sent to the vehicle control system 200 through the bracket device 300, reducing the cost. In addition, through the bracket device 300, the electronic device 400 can be powered, and the attitude adjustment instruction of the screen generated by the electronic device 400 according to the occupant image information obtained by the camera can also be sent to the vehicle control system, improving the convenience of use while adjusting the screen angle of the electronic device 400.

[0041] In one example, the above-mentioned transmission structure 340 can be only used to adjust the pitching angle of the placing part 350. Based on this, the transmission structure 340 can include a first connecting plate 341 and a second connecting plate 342. Among them, the first connecting plate 341 and the second connecting plate 342 are parallel to each other. The first ends of the first connecting plate 341 and the second connecting plate 342 are both fixedly connected to the bottom of the placing part 350. Connecting holes can be provided at the second ends of the first connecting plate 341 and the second connecting plate 342, and the connecting holes are used to connect with the rotating shaft of the first motor 330.

[0042] In one example, the above-mentioned placing part 350 can choose to adopt a clamping structure, and this clamping structure can adopt various mobile phone clamping structures that are widely used at present. Of course, the size of this clamping structure can be adaptively adjusted according to the size of the electronic device 500 to be placed. A universal serial bus (USB) interface can be provided on this clamping structure.

[0043] Of course, the above-mentioned bracket device 300 is only an exemplary implementation manner given in the embodiments of the present application. The bracket device 300 can also select any bracket device 300 that can adjust the pitching angle of the placing part under the control of the controller, and the embodiments of the present application do not make specific limitations on this.

[0044] In some implementation schemes, the bracket device 300 provided by the embodiments of the present application can also adjust the height. Among them, as Figure 4 shown, on the basis of Figure 3 the above-mentioned bracket device 300 can also include a lifting structure 370. This lifting structure 370 can specifically be used to adjust the height of the placing part 350, so as to realize the adjustment of the screen height of the electronic device 400. In one example, the first end of the lifting structure 370 can be fixedly connected to the bracket base 310. The second end of the lifting structure 370 can be connected to the first mounting part 360. The first mounting part 360 is used to mount the first motor 330, the transmission structure 340, the placing part 350, etc. The controller 320 can adjust the height of the lifting structure 370 according to the control instruction issued by the vehicle-mounted control system, so as to realize the adjustment of the screen height.

[0045] In a possible implementation, the above-mentioned lifting structure 370 can be implemented by an electric telescopic rod. Among them, the base of the electric telescopic rod (i.e., the first end of the lifting structure) is fixedly connected to the support seat 310. The top of the telescopic part of the electric telescopic rod (i.e., the second end of the lifting structure) is connected to the bottom of the first mounting part 360. Further, in order to enable the electric telescopic rod to adjust the height more stably, a fixing member can also be provided between the electric telescopic rod and the support seat 310. The function of this fixing member is to fix the electric telescopic rod to ensure that the position of the electric telescopic rod does not shift after the placement part 350 places the electronic device 400. Among them, the specific structure and setting method of this fixing member can not be specifically limited.

[0046] In a possible implementation, the above-mentioned lifting structure 370 can also include a rotating shaft and a second motor arranged along the height direction of the backrest of the first seat. The rotating shaft can be connected to the rotating shaft of the second motor. The second motor can be controlled by the controller 320. The first mounting part 360 can be provided with a first through hole with internal threads. The above-mentioned rotating shaft can be provided with threads matching the through hole, and the rotating shaft passes through the first through hole. In addition, a second through hole and a third through hole can be provided on the first mounting part 360 on both sides of the first through hole. At the same time, the support seat 310 can be provided with a first support rod passing through the first through hole and a second support rod passing through the second through hole. Among them, the heights of the first support rod, the rotating shaft, and the second support rod can be the same.

[0047] Based on this, when the second motor rotates, due to the limiting effect of the first support rod and the second support rod, the first mounting part 360 cannot rotate. At this time, the first mounting part 360 can only move up and down along the rotating shaft, thereby adjusting the height of the placement part. Among them, the above-mentioned lifting structures are all relatively common mechanical structures that can realize the lifting function through the control of the controller 320, and the embodiments of the present application will not elaborate here. In addition, in addition to the above several lifting structures, the lifting structure in the embodiments of the present application can also use other common mechanical structures that can realize the lifting function through the control of the controller 320, and the embodiments of the present application do not specifically limit this.

[0048] In a possible implementation, as Figure 5 shown, in Figure 4Based on this, the bracket device 300 provided in the embodiments of the present application may further include a rotating structure 390. A second mounting portion 380 may be provided on the rotating structure 390. The second mounting portion 380 is used to mount the lifting structure 370. Among them, the rotating structure 390 can drive the lifting structure 370 to rotate left and right, that is, drive the lifting structure 370 to rotate in a plane parallel to the bottom of the cockpit. In the above implementation process, the rotating structure 390 can select various mechanical structures that can achieve the above functions through the drive of a motor, and the embodiments of the present application do not make specific limitations on this.

[0049] In a possible implementation, the bracket device 300 may further include a telescopic structure. The telescopic structure can be disposed at any position between the bracket base 310 and the placement portion 350. Among them, the telescopic structure is used to adjust the distance between the placement portion and the occupant, that is, the telescopic structure can push the placement portion to move parallel to the bottom of the cockpit in the direction of the occupant. In one example, the telescopic structure can also be realized by an electric telescopic rod, or the telescopic structure can also be realized by a mechanical structure that can achieve the same or similar functions as the electric telescopic rod, and the embodiments of the present application do not make specific limitations on this.

[0050] In a possible implementation, as Figure 6 shown, the embodiments of the present application also provide a bracket device 300 as described above. The bracket device 300 may include a bracket base 310, a controller 320, a three-axis motor 610, and a placement portion 350. The bracket base 310 can be connected to the placement portion 350 through the three-axis motor 610. Through the three-axis motor 610, the pitch angle, height, and left and right rotation angles of the placement portion 350 can be adjusted simultaneously. Among them, the controller 320 can adjust at least one of the pitch angle, height, and left and right rotation angles of the placement portion 350 according to the control instructions sent by the vehicle-mounted control system 200. The three-axis motor 610 can select various common three-axis motor structures that can achieve the above functions, and the embodiments of the present application do not make specific limitations on this. Further, a connection port 351 is also provided on the placement portion 350 for supplying power to the electronic device 400. In addition, through the connection port 351, the electronic device 400 can also be communicatively connected to the vehicle-mounted control system 200.

[0051] It can be understood that the structure of the bracket device 300 described above is only some exemplary embodiments provided by the embodiments of the present application for easy understanding. In specific implementation, as long as the bracket device 300 provides the connection port 351 and can achieve any one of the adjustment methods such as the pitch angle, height, and left and right rotation angles, the embodiments of the present application do not make specific limitations on the specific structure of the bracket device 300.

[0052] In some embodiments, as Figure 7As shown, an embodiment of the present application further provides a vehicle control system 200, which includes a body controller 210, a front row seat adjustment device 220, a rear row seat adjustment device 230, and the above-mentioned bracket device 300. Among them, the front row seat adjustment device 220 is used to adjust the front-back position of the front row seat in the cockpit and the tilt angle of the seat back. The rear row seat adjustment device 230 is used to adjust the front-back position of the rear row seat in the cockpit and the tilt angle of the seat back. The above-mentioned electronic device 40, the front row seat adjustment device 220, and the rear row seat adjustment device 230 are all communicatively connected to the body controller 210. The body controller 210 can also control the front row seat adjustment device 220 to adjust the front-back position of the front row seat in the cockpit and the tilt angle of the seat back according to the head image information obtained by the camera of the electronic device 400. The above-mentioned bracket device 300 can be provided behind the backrest or headrest of the front row seat. In some solutions, in-seat sensors (such as pressure sensors) can be provided on each seat in the cockpit to detect whether there is someone sitting on each seat.

[0053] In a possible implementation, the above vehicle control system 200 can receive an attitude adjustment instruction of the screen sent by the bracket device. Then, according to the attitude adjustment instruction, adjust the pitch angle of the bracket device or the attitude of the first seat. Among them, the attitude adjustment instruction is used to indicate the pitch angle of the bracket device 300 or the attitude of the first seat.

[0054] In a possible implementation, the vehicle control system 200 can specifically adjust the pitch angle of the bracket device 300 when there is someone sitting on the first seat and there is also someone sitting on the second seat behind the first seat. In one example, when there are only two rows of seats in the cockpit, the above-mentioned first seat can be the driver's seat or the passenger seat in the cockpit, and the second seat can be the seat behind the driver's seat or the seat behind the passenger seat. Based on this, when there is someone on the first seat, only the pitch angle of the bracket device 300 can be adjusted to avoid affecting the experience of the occupants on the first seat by adjusting the attitude of the first seat. In one example, when there are more than three rows of seats in the cockpit, the above-mentioned first seat is any row of seats in the cockpit except the last row of seats at the tail of the cockpit, and the second seat is the row of seats behind the first seat.

[0055] In a possible implementation, when there is no one sitting on the first seat, but there is someone sitting on the second seat behind the first seat, adjust the pitch angle of the bracket device 300 or the attitude of the first seat. Based on this, when there is no one on the first seat but there is someone on the second seat, it is possible to choose to adjust the pitch angle of the bracket device 300 or the attitude of the first seat, or adjust both the pitch angle of the bracket device 300 and the attitude of the first seat at the same time, so as to adjust the screen more quickly.

[0056] In a possible implementation, when the attitude of the second seat changes, the vehicle-mounted control system 200 can also adjust the pitch angle of the bracket device 300. Among them, when the attitude of the second seat changes, the occupant image information also changes. Therefore, the pitch angle of the bracket device 300 can be adjusted according to requirements.

[0057] In a possible implementation, when the height and / or the left-right rotation angle of the bracket device 300 can be adjusted, the vehicle-mounted control system 200 can also adjust the height and / or the left-right rotation angle of the bracket device 300 according to the attitude adjustment instruction, so as to adjust the height and / or the left-right rotation angle of the screen of the electronic device 400.

[0058] In a possible implementation, as Figure 8 shown, the embodiment of the present application also provides a control method, and the execution process of the control method is described as follows.

[0059] S801: When there is someone sitting on the second seat behind the first seat, the electronic device acquires the occupant image information on the second seat.

[0060] Among them, when there is someone sitting on the second seat, the occupancy sensor provided on the first seat can send a corresponding detection signal to the body controller in the vehicle-mounted control system. After receiving the detection signal, the body controller can send an indication message to the electronic device, and the indication message is used to instruct the electronic device to start the camera to collect the occupant image information on the second seat.

[0061] S802: The electronic device generates an attitude adjustment instruction for the screen according to the occupant image information.

[0062] Among them, the above attitude adjustment instruction may include at least one of the pitch angle, height, and left-right rotation angle of the screen, etc. In specific implementation, the above attitude adjustment instruction can be adaptively adjusted according to the adjustment method supported by the bracket device.

[0063] In a possible implementation, software programs corresponding to the eye position recognition algorithm and the software program for generating the attitude adjustment instruction can be built into the vehicle-mounted control system. After the electronic device establishes a communication connection with the vehicle-mounted control system, the vehicle-mounted control system can send the above two software programs to the electronic device, so that the electronic device can recognize the eye position of the occupant according to the occupant image information collected by the camera, and generate an attitude adjustment instruction for the screen according to the eye position. Taking the pitch angle as an example, when the vehicle-mounted control system receives the in-position information fed back by the sensor on the second seat, it can send an instruction to the electronic device to instruct the electronic device to activate the camera to obtain the occupant image information. After the electronic device obtains the occupant image information, it can recognize the eye position of the occupant through the software program corresponding to the eye position recognition algorithm, then calculate the pitch angle that the screen needs to be adjusted according to the vertical distance between the eye position of the occupant and the center of the screen, and generate a corresponding attitude adjustment instruction according to the pitch angle.

[0064] Further, when the bracket device supports height adjustment, the above attitude adjustment instruction may also include indication information corresponding to the height to be adjusted. Among them, when the bracket device needs to adjust the height, the height of the screen can be adjusted first according to the vertical distance between the eye position of the occupant and the center of the screen. When the screen height adjustment is completed and the screen still cannot be directly facing the eyes of the occupant, then adjust the tilt angle of the screen. Of course, the above adjustment order is only an example given in the embodiments of the present application, and the adjustment order can be adjusted during specific implementation, and the embodiments of the present application do not make specific limitations on this.

[0065] Further, when the bracket device supports adjustment of the left-right rotation angle and the left-right rotation angle needs to be adjusted currently, the attitude adjustment instruction may also include indication information corresponding to the left-right rotation angle of the screen.

[0066] In a possible implementation, the electronic device can also only collect the occupant image information through the camera. Then, directly send the occupant image information to the vehicle-mounted control system for processing to obtain the pitch angle that the screen needs to be adjusted. Finally, adjust the bracket device according to the pitch angle so that the center of the screen is directly facing the eyes of the occupant.

[0067] Similarly, when the bracket device supports adjustment of the height and / or the left-right rotation angle, the attitude adjustment instruction may also include indication information corresponding to the left-right rotation angle of the screen and / or indication information corresponding to the height, which will not be elaborated in the embodiments of the present application.

[0068] S803: The bracket device receives the attitude adjustment instruction and sends the attitude adjustment instruction to the vehicle-mounted control system.

[0069] Among them, the bracket device can be communicatively connected to the vehicle control system in a wired or wireless manner. Among them, when the bracket device is communicatively connected to the vehicle control system in a wireless manner, wireless communication methods such as Bluetooth, ZigBee, StarFlash, and WiFi can be selected. The embodiments of the present application do not make specific limitations on this.

[0070] S804: When there is a person sitting on the second seat behind the first seat in the vehicle control system, but the first seat is unoccupied, the vehicle control system adjusts the pitch angle of the bracket device or the posture of the first seat.

[0071] Among them, the posture of the first seat may include the position of the first seat in the cockpit and / or the tilt angle of the backrest of the first seat. During actual adjustment, the posture of the first seat can select the corresponding adjustment method according to actual needs.

[0072] S805: After the adjustment is completed, this adjustment process is ended.

[0073] In a possible implementation, when the vehicle control system controls the bracket device and / or the first seat to complete the adjustment, if the eye position of the user does not change within 2 s, it can be considered that this adjustment process has been completed. At this time, this adjustment process can be ended.

[0074] In a possible implementation, when there is a person sitting on the first seat and there is also a person sitting on the second seat behind the first seat, the vehicle control system can adjust the pitch angle of the bracket device. At this time, because there is a person sitting on the first seat, if the posture of the first seat is adjusted, it will affect the occupants on the first seat. Therefore, only the pitch angle of the bracket device can be adjusted.

[0075] In a possible implementation, considering that the occupant may adjust the posture of the second seat during the process of riding in the car. At this time, the eye position of the occupant will change. Based on this, the electronic device can continuously detect the eye position of the occupant during use. Once the change in the eye position of the occupant exceeds the set threshold, the pitch angle of the bracket device or the posture of the first seat is readjusted.

[0076] In a possible implementation, if the bracket device supports adjusting the height and / or the left - right rotation angle, when there is a person sitting on the first seat and there is also a person sitting on the second seat behind the first seat, the vehicle control system can also adjust the height and / or the left - right selection angle of the bracket device.
