DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other different ways from those described herein; obviously, the embodiments described in the specification are only some embodiments of the present disclosure, not all embodiments.

[0034] Figure 1 A perspective structure schematic diagram of a vehicle steering wheel provided by an embodiment of the present disclosure is shown in FIG. 2. Figure 2 A side cross-sectional structure schematic diagram of a vehicle display device provided by an embodiment of the present disclosure is shown in FIG. 3. Figure 1 and Figure 2 The vehicle display device comprises: a touch display screen 1, which is arranged on a vehicle steering wheel 8; the vehicle display device further comprises a display control circuit board 2 and a steering wheel control circuit board 3, the display control circuit board 2 is in communication connection with the touch display screen 1 and the steering wheel control circuit board 3 respectively, and the display control circuit board 2 is used for controlling the touch display screen 1 according to a display control instruction sent by the steering wheel control circuit board 3; the display control circuit board 2 and the steering wheel control circuit board 3 are arranged on one side of the touch display screen 1 in a stacked manner and are arranged in an integrated manner in an independent space of the vehicle display device.

[0035] Specifically, in combination with Figure 1 and Figure 2 For example, a user can obtain content such as a reversing image, navigation information, mileage information or vehicle speed information by touching a corresponding interactive icon in the interactive icon display area of the touch display screen 1, and preferably set the touch display screen 1 in a manner as shown in Figure 1The position of the touch display screen 1 in the middle area of the vehicle steering wheel 8 close to the top can make the driver observe the content of the touch display screen 1 without deviating from the driving route during driving, realizing convenient human-vehicle interaction and improving driving safety.

[0036] The display control circuit board 2 is connected with the touch display screen 1 and the steering wheel control circuit board 3 through wired or wireless communication. The steering wheel control circuit board 3 can be connected with the controller of the vehicle, such as VCU (Vehicle Control Unit) or ECU (Electronic Control Unit) through the CAN (Controller Area Network) communication port, realizing communication connection with the central control screen, instrument panel or car computer of the vehicle to exchange information. For example, the driver can input the instruction of going forward or backward to the VCU in the vehicle by touching the touch display screen 1. The steering wheel control circuit board 3 controls the corresponding rotation of the vehicle motor according to the specific instruction input by the user, or realizes the display and interaction of the automatic driving information and ADAS (Advanced Driving Assistance System) information of the vehicle through the touch display screen. The specific display content and the realized interaction function of the touch display screen are not limited in the embodiments of the present disclosure. The steering wheel control circuit board 3 can also send the display control instruction to the display control circuit board 2, and the display control circuit board 2 controls whether the touch display screen 1 displays and the specific display content of the touch display screen 1 according to the received display control instruction. In addition, the steering wheel control circuit board 3 can also provide the function of networking, realizing the control of the basic functions of the vehicle steering wheel 8, such as the control of the horn, on-off signal, networking, message or human-computer interaction interface, etc. At the same time, the steering wheel control circuit board 3 can regularly update and maintain the display system during the networking process, supporting OTA (Over-the-Air Technology) online upgrade.

[0037] Since the display control circuit board 2 and the steering wheel control circuit board 3 are both multi-signal high-frequency circuit boards, if the circuit structures in the two are placed in the same circuit board, the area of the circuit board will be large, and the two will have serious electromagnetic interference phenomena, such as signal noise and the like, and the dense circuit elements on the circuit board are not conducive to heat dissipation of the circuit board. The display control circuit board 2 and the steering wheel control circuit board 3 are arranged in layers on one side of the touch display screen 1 and integrated in the independent space of the vehicle display device according to the embodiment of the present disclosure. The independent space of the vehicle display device can only occupy 20% of the total volume of the vehicle steering wheel 8. Thus, the display control circuit board 2 and the steering wheel control circuit board 3 are arranged in a small space, and the problem of electromagnetic interference and heat dissipation between the circuit boards is solved.

[0038] The display control circuit board 2 is in communication connection with the touch display screen 1 and the steering wheel control circuit board 3 respectively according to the embodiment of the present disclosure. The information is intelligently interacted and processed through the steering wheel control circuit board 3. The display control circuit board 2 is used to control the touch display screen 1 according to the display control instruction sent by the steering wheel control circuit board 3, so that the driver can view the vehicle state information without moving the line of sight from the driving direction during driving, and the interaction between the driver and the vehicle is more convenient, which effectively improves the safety, convenience and comfort of vehicle driving. At the same time, the display control circuit board 2 and the steering wheel control circuit board 3 are arranged in layers on one side of the touch display screen 1 and integrated in the independent space of the vehicle display device, which realizes the arrangement of the display control circuit board 2 and the steering wheel control circuit board 3 in a small structural space. The small structural space may be, for example, but is not limited to, one fourth of the overall space of the steering wheel. The space of the vehicle steering wheel is saved, and the problem of electromagnetic interference and heat dissipation between the display control circuit board 2 and the steering wheel control circuit board 3 is solved through the layer arrangement.

[0039] Optionally, as shown in Figure 2 The steering wheel control circuit board 3 is in communication connection with the display control circuit board 2 through the flexible connection structure 21.

[0040] Specifically, as shown in Figure 2As shown, the steering wheel control circuit board 3 can be preferably arranged on the side of the display control circuit board 2 away from the touch display screen 1, and the steering wheel control circuit board 3 and the display control circuit board 2 are stacked in layers, avoiding mutual interference of electromagnetic waves and solving the heat dissipation problem of the circuit board. The steering wheel control circuit board 3 can be connected in wired communication with the display control circuit board 2 through the flexible connection structure 21, which can realize communication connection in a small and limited independent space. The flexible connection structure 21 can be, for example, a FPC (Flexible Printed Circuit), which has high wiring density, light weight, thin thickness, and good bending property.

[0041] Figure 3 A schematic diagram of a planar structure of a touch display screen is provided for the embodiments of the present disclosure. Optionally, in combination with Figure 2 and Figure 3 The touch display screen 1 is preferably arranged on the upper region of the vehicle steering wheel 8, and the touch display screen 1 includes a liquid crystal touch display screen 11 and a backlight structure 12. The backlight structure 12 is arranged on the side of the liquid crystal touch display screen 11 close to the display control circuit board 2, and the backlight structure 12 includes a matrix arrangement of MiniLEDs 121.

[0042] Specifically, since the liquid crystal touch display screen 11 is a kind of non-active light-emitting electronic device and does not have light-emitting characteristics itself, it must rely on the backlight structure 12 to obtain display performance. Therefore, the liquid crystal touch display screen 11 further includes a liquid crystal module and a touch module. The display control circuit board 2 controls the arrangement direction of the liquid crystal in the liquid crystal cell by applying an electrical signal to the electrodes in the liquid crystal cell. The display control circuit board 2 simultaneously controls the display content and brightness of the liquid crystal touch display screen 11 by controlling the brightness of the backlight structure 12. The touch module includes touch electrodes and realizes recognition of the touch instructions input by the user. The display content and brightness of the liquid crystal touch display screen 11 are determined by the backlight structure 12. The backlight structure 12 is arranged on the side of the liquid crystal touch display screen 11 close to the display control circuit board 2. It should be noted that the display control principle and touch principle of the liquid crystal display screen are well known to those skilled in the art, and will not be described here. In addition, the touch display screen 1 can also be a display screen using OLED (Organic Light-Emitting Diode), MicroLED (Micro Light-Emitting Diode), MiniLED (Mini Light-Emitting Diode), etc. display technology, and the embodiments of the present disclosure do not make specific limitations on this.

[0043] The backlight structure 12 can include, for example, Figure 3The matrix arranged MiniLED (Mini Light Emitting Diode) shown is arranged in a large number of dense arrangements to achieve area dimming in a smaller range, to achieve better brightness uniformity, higher color contrast and higher brightness index in a smaller light mixing distance, and can achieve a display effect of 1000000:1 contrast ratio, which is 1000 times higher than the contrast ratio of 1000:1 of a common touch display screen, thereby avoiding the problem of screen glare when driving at night, and providing a comfortable screen brightness for the driver. That is, the MiniLED Local Dimming light source technology is adopted in the embodiment of the present disclosure, so that the display area brightness adjustment and screen glare protection functions can be realized, and the user experience and driving safety are improved.

[0044] Figure 4 A display schematic diagram of a vehicle-mounted display device provided by the embodiment of the present disclosure is shown in FIG. 1. As shown in the figure, when it is necessary to display a parking interactive icon pattern, the MiniLED 121 of the interactive icon display area 113 of the parking is turned on to light up the interactive icon pattern of the parking, and the MiniLED 121 in the display area 112 outside the interactive icon display area 113 of the parking is turned off, that is, the display area 112 outside the interactive icon display area 113 is displayed as black. Thus, by controlling the pixel units in the area outside the interactive icon display area 113 in the display area 112 to be turned off, the touch display screen 1 and the surrounding environment are integrated, and the visual effect of the vehicle-mounted display device is optimized. It should be noted that the number of MiniLED 121 in the display area 112 can be set according to the size of the display area 112 and the required brightness, and the embodiment of the present disclosure does not limit this. In addition, as shown in FIG. 2, the embodiment of the present disclosure adopts a unique double-layer circuit board space three-dimensional fixed assembly structure to realize the function of arranging two layers of circuit boards and MiniLED light source controllers in a small space.

Figure 6 A back three-dimensional structure schematic diagram of a vehicle-mounted display device provided by the embodiment of the present disclosure is shown in FIG. 4. Optionally, in combination with Figure 1 、 Figure 2 、 Figure 5 and Figure 6 ​​The vehicle display device further comprises a decorative part 4 and a rear shell 5. The decorative part 4 comprises a connecting part 412 and a first mounting position 53. The connecting part 412 is used to connect the base of the steering wheel 8. The first mounting position 53 is used to mount the touch display screen 1, such as a liquid crystal touch display screen 11. The rear shell 5 is mounted on the side of the decorative part 4 close to the base corresponding to the first mounting position 53. An independent space is formed between the rear shell 5 and the decorative part 4. The rear shell 5 is provided with an opening 51 to expose the power connector on the steering wheel control circuit board 3.

[0046] Specifically, in combination with Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the decorative part 4 in the vehicle display device is used to connect the screen assembly and the steering wheel 8 skeleton. The connecting part 412 can be arranged on the four frames of the decorative part 4. The decorative part 4 can be fixed to the base of the vehicle steering wheel 8 through the connecting part 412. The decorative part 4 comprises an annular support surrounding the touch display screen 1. An independent area 9 is arranged on one side of the annular support. Figure 1 、 Figure 5 and Figure 6 do not show the vehicle airbag. Figure 1 The cover plate 25 is shown in . The cover plate 25 covers the vehicle airbag arranged in the independent area 9. The cover plate 25 is also provided with a vehicle horn system corresponding to the cover plate 25. The vehicle horn can be activated by pressing the cover plate 25. When the vehicle collides with other vehicles or obstacles, the vehicle airbag can be normally ejected. The ejected vehicle airbag can protect the driver's head and front chest and other important organs, thereby protecting the life safety of the driver. In addition, the liquid crystal touch display screen 11 can be fixed in the annular support in an embedded manner, forming a whole with the vehicle steering wheel 8 and rotating with the steering of the vehicle steering wheel.

[0047] In addition, Figure 1 、 Figure 5 and Figure 6 only show the shape of the decorative part 4. The specific shape of the decorative part 4 is not limited in the embodiments of the present disclosure, as long as the decorative part 4 can be adapted to the touch display screen 1, the airbag and the base of the steering wheel 8. The appearance design and the fixing structure design of the decorative part 4 realize the effective arrangement of the display system, the airbag system and the car horn system in the central narrow area of the steering wheel, realizing the technical function and the beautiful appearance at the same time. The decorative part 4 adopts the ABS (Acrylonitrile-Butadiene-Styrene) chromium plating process, which meets the requirements of beautiful appearance and provides electrostatic protection for the vehicle display device. The unique material and structure of the decorative part 4 of the steering wheel effectively integrate the electronic protection and the structure assembly function.

[0048] The rear shell 5 and the decorative piece 4 are fixedly connected to form an independent space. For example, a screw structure is arranged on the rear shell 5, a threaded structure is arranged on the decorative piece 4, the screw structure on the rear shell 5 is rotationally connected with the threaded structure on the decorative piece 4, and the rear shell 5 is fixedly connected to the decorative piece 4. As shown in Figure 1 , custom key control areas can be arranged on both sides of the decorative piece 4, which can integrate the control of vehicle lights, volume, and other functions, and are set according to the use of the vehicle, which is not limited in the embodiments of the present disclosure.

[0049] The display control circuit board 2 and the steering wheel control circuit board 3 and the related circuit wires are arranged in the independent space formed by the rear shell 5 and the decorative piece 4, which realizes the storage effect of the circuit board and the wires, avoids the display control circuit board 2 and the steering wheel control circuit board 3 from being exposed to the outside and being damaged by sewage or dust, and improves the neatness and safety of the vehicle-mounted display device. The power connector of the steering wheel control circuit board 3 is exposed through the opening 51 arranged on the rear shell 5, which facilitates the connection between the vehicle power supply such as a low-voltage storage battery or a direct-current converter and the power connector to supply power to the steering wheel control circuit board 3, facilitates the wiring connection between the vehicle and the vehicle-mounted display device, and facilitates the signal interaction between the steering wheel control circuit board 3 and the vehicle machine.

[0050] Figure 7 A cross-sectional structure schematic diagram of a vehicle-mounted display device provided by the embodiments of the present disclosure is shown. Optionally, in combination with Figure 2 and Figure 7 , the first layer of fixed column structures 6 and the second layer of fixed column structures 7 are arranged on the side of the backlight structure 12 close to the display control circuit board 2, Figure 2 only the second layer of fixed column structures 7 is exemplarily shown, the first layer of fixed column structures 6 is used to fix the display control circuit board 2 to the backlight structure 12, and the second layer of fixed column structures 7 is used to fix the backlight structure 12 and the steering wheel control circuit board 3 to the rear shell 5.

[0051] Specifically, in combination with Figure 2 and Figure 7 , in order to relatively fix the backlight structure 12, the steering wheel control circuit board 3, the display control circuit board 2, and the rear shell 5, the first layer of fixed column structures 6 and the second layer of fixed column structures 7 are arranged on the side of the backlight structure 12 close to the display control circuit board 2, Figure 6 in the embodiment, the height of the first layer of fixed column structures 6 is lower than that of the second layer of fixed column structures 7, and the first layer of fixed column structures 6 and the second layer of fixed column structures 7 are arranged in a staggered manner, the display control circuit board 2 is fixed to the backlight structure 12 by the first layer of fixed column structures 6, and the backlight structure 12 and the steering wheel control circuit board 3 are fixed to the rear shell 5 by the second layer of fixed column structures 7, especially with reference to Figure 2For example, the second layer of the fixed column structure 7 can be internally hollow, and the inner wall of the hollow structure is provided with a threaded structure. By rotating the screw 52 outside the rear shell 5, the backlight structure 12 is fixed relative to the rear shell 5. After the screw 52 is tightened, the backlight structure 12 and the rear shell 5 clamp the steering wheel control circuit board 3 to fix the steering wheel control circuit board 3. In this way, the display control circuit board 2, the steering wheel control circuit board 3 and the backlight structure 12 are fixedly assembled in a separate narrow space, saving vehicle space and improving the firmness of the vehicle-mounted display device mounted on the vehicle steering wheel 8. In the case of vehicle bumping or collision, it will not affect the use of the vehicle-mounted display device.

[0052] Optionally, in combination with Figure 1 、 Figures 3 to 5 The touch display screen 1, for example, the liquid crystal touch display screen 11, includes a touch area 111 and a display area 112. The area of the touch area 111 is greater than the area of the display area 112, and the touch area 111 covers the display area 112. The display area 112 is provided corresponding to the backlight structure 12, and the backlight structure 12 adopts a direct type MiniLED 121.

[0053] Specifically, in combination with Figure 1 、 Figures 3 to 5 The touch display screen 1 can include a touch area 111 and a display area 112. The area of the touch area 111 is set to be greater than the area of the display area 112, and the touch area 111 covers the display area 112. The display area 112 can be used to display content for realizing human-vehicle interaction, for example. The driver can control the vehicle to perform corresponding operations by touching the touch area 111 corresponding to the display area. The part of the touch area 111 beyond the display area 112 is a reserved area, which can be added with icon controllers and other elements according to the vehicle use demand, such as media controllers, navigation controllers, restart controllers and volume controllers, to meet the diversification and flexibility of human-vehicle interaction functions.

[0054] The touch area 111 can include a touch structure separately provided from the devices in the display area 112, or a touch structure integrated with the display screen and simultaneously manufactured in the manufacturing process of the display area 112. For example, the touch area 111 can be in a touch mode of OGS (One Glass Solution), in-cell, on-cell or GFF (Glass Film Film). The touch area 111 and the display area 112 can be attached together using double-sided adhesive, foam or transparent adhesive, achieving the effect of integration of touch and display, while reducing internal reflection between the touch area 111 and the display area 112, and optimizing the display effect of the touch display screen.

[0055] Specifically, the display area 112 can be arranged in a quasi-rectangular shape, for example Figure 1 、 Figure 3 and Figure 5 The four corners of the display area 112 are rounded, for example, the four corners can be designed with a radius of 2.0mm (radius 2.0mm), so that the display area 112 effectively matches the overall smooth appearance of the vehicle steering wheel 8, improving the appearance of the vehicle. The width-to-length ratio of the display area 112 is equal to 1:N, N is greater than or equal to 4 and less than or equal to 6. The width of the display area 112 is the dimension of the display area 112 along the arrangement direction of the annular support and the independent area 9, Figure 3 L represents the length of the display area 112, and W represents the width of the display area 112. The touch display screen 1 can use a 4.8-inch LCD (Liquid Crystal Display) technology, and the size of the display area 112 can be set to 120*24mm, i.e. the width is 24mm and the length is 120mm. The resolution can reach 800*RGB*166, i.e. the number of three primary colors is 800*3*166, which can meet the display requirements of the retina level. The width-to-length ratio of the display area 112 can be 1:5, which meets the unique 1:5 golden display ratio of the steering wheel 8 structure, which is beneficial to the array layout of the interactive icon pattern. Therefore, by arranging the display area 112 in a quasi-rectangular shape, the width-to-length ratio of the display area 112 is equal to 1:N, which meets the integration of the multi-functional system of the narrow structure area of the vehicle steering wheel 8, including display, touch, software system, horn system, airbag and other systems, and is beneficial to the display of the arrayed interactive icon pattern of the touch display screen 1, improving the display effect of the touch display screen 1.

[0056] In the prior art, the backlight structure 12 corresponding to the display area 112 usually has two types of side-in backlight structure 12 and direct backlight structure 12. Only less than half of the light emitted by the light source in the side-in backlight structure 12 can be emitted from the light-emitting surface of the display area 112, resulting in low light-emitting efficiency, high power consumption, and poor display brightness and uniformity of the corresponding display area 112. The present embodiment uses direct MiniLED 121, and the light emitted by the MiniLED 121 can be directly irradiated upward to the display area 112 and emitted from the light-emitting surface, improving the light-emitting efficiency. In addition, by controlling the brightness of the direct MiniLED 121, it can be directly controlled whether the interactive icon display area is displayed, Figure 3 For example, the display area 112 includes three interactive icon display areas 113, and each interactive icon display area 113 includes 12 direct MiniLEDs 121.

[0057] In order to make the interactive icon display area 113 more regular, the plurality of interactive icon display areas 113 are arranged in a matrix in the display area 112. The length and width of the matrix of the interactive icon display areas 113 can be set according to the shape and size of the interactive icon display pattern. The interactive icon display area 113 with the proximity function is arranged adjacent to the interactive icon display area 113.
