DETAILED DESCRIPTION

[0029] 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.

[0030] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present disclosure, not all the embodiments.

[0031] Figure 1 A three-dimensional structural schematic view of a vehicle steering wheel provided by an embodiment of the present disclosure is shown in FIG. 4. Figure 2 A three-dimensional structural schematic view of a vehicle display device provided by an embodiment of the present disclosure is shown in FIG. 5. In combination with the above-mentioned Figure 1 and Figure 2The vehicle-mounted display device comprises a trim 1, the trim 1 comprising a connecting portion 113 for connecting a base of a vehicle steering wheel 3, a first mounting position 11 and a second mounting position 5 for mounting a vehicle airbag, the first mounting position 11 being above the second mounting position 5 along an extension direction of the base. The vehicle-mounted display device further comprises a touch display screen 2, the first mounting position 11 being for mounting the touch display screen, the touch display screen 2 being arranged in a trapezoidal shape and being detachable from the trim 1 under an external force, the trim 1 surrounding the touch display screen 2, an edge of the touch display screen 2 being away from the vehicle airbag being shorter than an edge of the touch display screen 2 being adjacent to the vehicle airbag, and Figure 1 the upper edge of the touch display screen 2 being shorter than the lower edge, two corners of the touch display screen 2 being away from the vehicle airbag being arranged in a circular arc shape, and a contour of the trim 1 at the first mounting position 11 matching a contour of the touch display screen 2.

[0032] Specifically, in combination with Figure 1 and Figure 2 , the trim 1 serves to connect a screen assembly and a steering wheel skeleton, connecting portions 113 can be arranged on four frame edges of the trim 1, and the trim 1 is fixed to the base of the steering wheel 3 through the connecting portions 113, Figure 1 and Figure 2 neither of which shows a vehicle airbag, Figure 1 shows a cover plate 4 covering the vehicle airbag arranged in the second mounting position 5, and the cover plate 4 is further provided with a vehicle horn system corresponding thereto, and the vehicle horn can be activated by pressing the cover plate 4. When a vehicle collides with another vehicle or an obstacle, the vehicle airbag can be normally ejected to protect important organs such as the head and the chest of the driver, thereby ensuring the safety of the driver.

[0033] Exemplarily, custom key control areas 6 as shown in Figure 1 can be arranged on both sides of the trim 1 respectively, which can integrate the control of functions such as vehicle headlights and volume, and the arrangement can be set according to the use of the vehicle, which is not limited in the embodiments of the present disclosure. In addition, Figure 1 and Figure 2 only exemplarily show the shape of the trim 1, and the specific shape of the trim 1 is not limited in the embodiments of the present disclosure, as long as the trim 1 can be adapted to the touch display screen 2, the vehicle airbag and the base of the steering wheel 3.

[0034] The vehicle-mounted display device further comprises a touch display screen 2, 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 an interactive icon display area of the touch display screen 2, for example, and the touch display screen 2 is fixed to the trim 1 in an embedded manner. Exemplarily, the touch display screen 2 can be arranged as shown inFigure 1 and Figure 2 The touch display screen 2 is arranged in the upper position of the middle region of the steering wheel 3, which is convenient for the driver to watch. Thus, the embodiment of the present disclosure realizes the effective arrangement of the touch display screen 2, the vehicle airbag system and the automobile horn system in the narrow central region of the steering wheel 3 by using the appearance design and the fixing structure design of the trim 1, which realizes the technical function and the aesthetic appearance of the steering wheel 3. In addition, the embodiment of the present disclosure realizes the structure scheme of parallel arrangement of the display system and the vehicle airbag, which can realize the convenient man-machine interaction display touch without affecting the functions of the vehicle airbag and the automobile horn, realizes the effective system integration of the vehicle safety function and the display function, and realizes the convenient operation scheme of the driving personnel to quickly identify the driving information and the related man-machine interaction at the position of the steering wheel 3 on the basis of the existing functions of the steering wheel 3.

[0035] When the vehicle airbag pops out due to the impact of the vehicle, the area where the vehicle airbag is located will apply external extrusion force to the area where the touch display screen 2 is located, and if the two corners of the touch display screen 2 far away from the vehicle airbag are arranged in sharp right angles, the stress of the corresponding position is large when the position is extruded by external force. The large impact force applied by the vehicle airbag when it pops out can easily cause the glass cover plate of the touch display screen 2 to break, which can easily cause secondary injury to the people in the vehicle when the vehicle is in a collision.

[0036] In combination with Figure 1 and Figure 2 , the embodiment of the present disclosure is arranged to have a shape similar to a trapezoid, and the touch display screen 2 can be separated from the trim 1 under external force, that is, the length of the edge of the touch display screen 2 far away from the vehicle airbag is less than the length of the edge of the touch display screen 2 close to the vehicle airbag, and the two corners of the touch display screen 2 far away from the vehicle airbag are arranged in arc corners. The design of the arc corners greatly reduces the pressure of the corresponding position of the touch display screen 2 when the touch display screen 2 is extruded by external force. When the vehicle airbag pops out and applies a large external force to the side where the touch display screen 2 is located, the design of the arc corners can buffer the extrusion pressure when the vehicle airbag is used to the limit or a large external force extrudes the cover plate glass from the center of the steering wheel. The touch display screen 2 can be safely slid out or discharged from the narrow side of the trapezoidal shape, which greatly reduces the probability of breakage of the cover glass of the touch display screen 2. Thus, the embodiment of the present disclosure can realize the display touch man-machine interaction control function, and at the same time, the appearance design and the safety function are realized. The risk problem of breakage of the glass cover plate of the touch display screen 2 in the traffic accident scene of the vehicle collision is solved. By designing the shape of the glass cover plate of the touch display screen 2 and arranging the touch display screen 2 to be separated from the trim 1 under external force, the function of the touch display screen 2 in the steering wheel 3 region is realized, the purpose of safety protection for the driver and the passenger is met, and excellent display appearance and smooth touch are realized.

[0037] Exemplarily, the two corners of the touch display screen 2 close to the airbag of the vehicle can also be provided with circular arc corners, that is, the four corners of the touch display screen 2 similar to a trapezoidal shape are all provided with circular arc corners, or the two corners of the touch display screen 2 close to the airbag of the vehicle can also be provided with right angles, and the present disclosure does not limit this. Figure 1 and Figure 2 as shown, the two corners of the touch display screen 2 close to the airbag of the vehicle are provided with right angles, and the present disclosure does not limit this.

[0038] Therefore, by using the appearance design and fixing structure design of the decorative part 1, the present disclosure effectively arranges the touch display screen 2, the airbag system of the vehicle, and the horn system of the vehicle in the central narrow area of the steering wheel, realizes the technical function while realizing the beautiful appearance of the steering wheel 3. In addition, the present disclosure solves the risk problem of the glass cover plate of the touch display screen 2 breaking in the traffic accident scene of the vehicle collision, and by designing the shape of the glass cover plate of the touch display screen 2 and setting the touch display screen 2 to be separated from the decorative part 1 under the action of external force, the purpose of meeting the safety protection of the driver and passenger is realized while the display screen function is added in the area of the steering wheel 3, and excellent display appearance and smooth touch are realized.

[0039] Figure 3 A side view structure schematic diagram of a vehicle-mounted display device provided by the present disclosure, Figure 4 A partial enlarged schematic diagram of the side view structure of a vehicle-mounted display device provided by the present disclosure. In combination with Figures 1 to 4 The touch display screen 2 is fixed to the decorative part 1 at the first mounting position 11 through the cover plate structure 23 in the touch display screen 2, and the upper and lower edge corners of the cover plate structure 23 are provided with circular arc corners in the direction perpendicular to the plane where the touch display screen 2 is located. Exemplarily, the touch display screen 2 can include a liquid crystal display screen and a backlight structure 222, and the liquid crystal display screen includes the cover plate structure 23, such as a glass cover plate and a liquid crystal box. The working principle of the liquid crystal display screen is well known to those skilled in the art, and will not be described here. It should be noted that the touch display screen 2 can also be an OLED (Organic Light-Emitting Diode), a Micro LED (Micro Light-Emitting Diode), a Mini LED (Mini Light-Emitting Diode), etc. The present disclosure does not limit this.

[0040] Figure 3 and Figure 4R in the formula represents the circular arc angle of the upper and lower edges of the cover plate structure 23. The upper and lower edges of the cover plate structure 23 around the periphery can be provided with circular arc angles. If the upper and lower edges of the cover plate structure 23 around the periphery are provided with sharp right angles, the stress is large when the corresponding position is extruded by external force. The large impact force applied by the vehicle airbag when it pops out can easily cause the glass cover plate of the touch display screen 2 to break. The design of the upper and lower edge angles of the cover plate structure 23 as circular arc angles greatly reduces the pressure on the corresponding position of the touch display screen 2 when it is extruded by external force. When the vehicle airbag pops out and instantaneously applies a large external force to the side where the touch display screen 2 is located, the design of the upper and lower edge angles of the cover plate structure 23 as circular arc angles can buffer the extrusion pressure when the vehicle airbag is used to the limit or a large external force extrudes the cover plate glass from the center of the steering wheel. The touch display screen 2 can be safely slid out or safely discharged from the narrow side of the ladder-shaped side, greatly reducing the probability of breakage of the cover plate glass of the touch display screen 2.

[0041] Optionally, in combination with Figures 1 to 4 , the decorative piece 1 at the first mounting position 11 comprises a ring-shaped support structure 111 and a ring-shaped side wall structure 112, the ring-shaped support structure 111 is used to support the cover plate structure 23 in the touch display screen 2, and the ring-shaped side wall structure 112 is located on one side of the ring-shaped support structure 111 close to the cover plate structure 23 and is arranged around the cover plate structure 23.

[0042] Specifically, in combination with Figures 1 to 3 , the ring-shaped support structure 111 can support the cover plate structure 23 in the touch display screen 2, the ring-shaped support structure 111 can be a continuous ring-shaped structure or a discontinuous ring-shaped structure, as long as the area surrounded by the ring-shaped support structure 111 is smaller than the area of the cover plate structure 23. The ring-shaped side wall structure 112 is located on one side of the ring-shaped support structure 111 close to the cover plate structure 23 and is arranged around the cover plate structure 23. In order to prevent the edge of the cover plate structure 23 from being exposed to the outside and colliding with the outside to cause the touch display screen 2 to break, the ring-shaped side wall structure 112 is provided to protect the cover plate structure 23, and the inlaid installation of the touch display screen 2 is realized, and the fixed installation of the decorative piece 1 and the touch display screen 2 is realized.

[0043] Optionally, in combination with Figures 1 to 4 , the ring-shaped side wall structure 112 is arranged in a ladder-shaped shape, and the ring-shaped side wall structure 112 at least has a first side wall away from the side of the vehicle airbag, that is Figure 3 the side wall marked as 112 in the formula is inclined to the direction away from the cover plate structure 23 by a first set angle a.

[0044] Specifically, in combination with Figures 1 to 4 , the ring-shaped side wall structure 112 of the decorative piece 1 is a three-dimensional and inverted trapezoidal structure, Figure 4The first side wall of the annular side wall structure 112 at least away from the side of the vehicle airbag is inclined to the direction away from the cover plate structure 23 at a first set angle α of 3°. Since the decorative part 1 is made of ABS plastic (Acrylonitrile-Butadiene-Styrene) material by stamping and injection molding, the annular side wall structure 112 has deformability. The deformable inclination design of the annular side wall structure 112 greatly reduces the pressure on the corresponding position of the touch display screen 2 when the touch display screen 2 is subjected to external extrusion force. When the vehicle airbag pops out and instantaneously applies a large external force to the side where the touch display screen 2 is located, the inclination design of the annular side wall structure 112 can buffer the extrusion pressure when the vehicle airbag is used to the limit or a large external force extrudes the cover plate glass from the center of the steering wheel 3 outward. The touch display screen 2 can be safely slid out or discharged outward from the narrow side of the ladder-shaped annular side wall structure 112, greatly reducing the probability of glass breakage of the touch display screen 2 cover plate structure 23. In addition, the surface of the decorative part 1 realizes the appearance and electronic structure function of the part through the process of chrome plating and paint spraying, which not only meets the aesthetic appearance, but also provides the touch display screen 2 with the technical function of static protection and the ability of structural rigidity and elasticity.

[0045] It should be noted that the first side wall of the annular side wall structure 112 at least away from the side of the vehicle airbag is inclined to the direction away from the cover plate structure 23 at a first set angle, which can meet the requirement that the touch display screen 2 can slide out of the decorative part 1 along the annular side wall structure 112 when the vehicle is in a collision. The specific size of the first set angle is not limited in the embodiment of the present disclosure.

[0046] Optionally, in combination with Figures 1 to 4 , two side walls adjacent to the first side wall in the annular side wall structure 112 are inclined to the direction away from the cover plate structure 23 at a second set angle.

[0047] Specifically, in combination with Figures 1 to 4 , the annular side wall structure 112 has two side walls adjacent to the first side wall, that is, Figure 1 the left and right side walls of the annular side wall structure 112 in the above embodiment, the two side walls are inclined to the direction away from the cover plate structure 23 at a second set angle. When the vehicle airbag pops out and instantaneously applies a large external force to the side where the touch display screen 2 is located, the two side walls inclined to the direction away from the cover plate structure 23 at the second set angle can buffer the extrusion pressure when the vehicle airbag is used to the limit or a large external force extrudes the cover plate structure 23 glass from the center of the steering wheel 3 outward. The touch display screen 2 can be safely slid out or discharged outward from the narrow side of the ladder-shaped annular side wall structure 112, greatly reducing the probability of glass breakage of the touch display screen 2 cover plate. It should be noted that the second set angle is not limited in the embodiment of the present disclosure, as long as the touch display screen 2 can slide out of the decorative part 1 along the annular side wall structure 112 under a large external force.

[0048] Optionally, in combination with Figures 1 to 4 The cover plate structure 23 is pasted to the annular support structure 111 through the adhesive structure 24. Specifically, in order to firmly paste the touch display screen 2 and the steering wheel 3 together, the cover plate structure 23 is pasted to the annular support structure 111 through the adhesive structure 24, for example, high-stability double-sided tape, for example, transparent tape. The four edges of the touch display screen 2 are tightly bonded to the annular support structure 111 through the transparent tape, which is beneficial to realize the narrow-frame design of the touch display screen 2 on the steering wheel 3, effectively reduces the frame size of the touch display screen 2, further improves the effective area ratio of the display area of the touch display screen 2, and the touch display screen 2 can display more human-vehicle interaction content, thereby improving the information interaction capability of the steering wheel 3.

[0049] In addition, if the cover plate structure 23 of the touch display screen 2 is fixed to the annular support structure 111 by using a fixed buckle or the like, the glass of the cover plate structure 23 is easily broken when the touch display screen 2 is subjected to external extrusion force, for example, instantaneous external extrusion force applied when the vehicle airbag is popped out. In the embodiment of the present disclosure, the cover plate structure 23 is pasted to the annular support structure 111 through the adhesive structure 24. When the touch display screen 2 is subjected to external extrusion force, for example, instantaneous external extrusion force applied when the vehicle airbag is popped out, when the force in the corresponding direction of the external applied pressure is greater than the adhesive force of the adhesive structure 24, the touch display screen 2 can be completely discharged from the annular support structure 111, thereby effectively reducing the probability of the cover plate structure 23 of the touch display screen 2 being broken by extrusion. In combination with Figure 3 and Figure 4 The mounting gap 25 can be arranged between the upper and lower frames of the touch display screen 2 and the annular support structure 111.

[0050] Optionally, in combination with Figures 1 to 4 The surface of the touch display screen 2 away from the base is lower than the surface of the decorative part 1 away from the base, that is, the upper surface of the touch display screen 2 is lower than the upper surface of the decorative part 1. Specifically, when the vehicle collides with other vehicles or obstacles, the vehicle airbag of the vehicle is popped out to protect the important organs of the driver. In order to avoid the touch display screen 2 being broken when the vehicle airbag is popped out, the upper surface of the touch display screen 2 is lower than the upper surface of the decorative part 1, Figure 4 The height difference between the upper surface of the touch display screen 2 and the upper surface of the decorative part 1 is H, which can be 0.3 mm. Thus, the upper surface of the touch display screen 2 is lower than the upper surface of the module of the vehicle airbag, which effectively avoids the structural interference when the vehicle airbag function is implemented, prevents the cover plate structure 23 from being broken by the vehicle airbag, and effectively prevents the cover plate structure 23 from cutting the vehicle airbag.

[0051] In addition, the cliff structure formed by the height difference between the edge of the first mounting position 11 and the upper surface of the touch display screen 2 can prevent the cover plate edge in the touch display screen 2 from colliding with the driver, thereby avoiding the collision with the body parts of the driver. The decorative part 1 forms an L-shaped step structure. Since the decorative part 1 is made of ABS plastic and is plated, the ABS plastic can prevent the touch display screen 2 from being extruded and deformed by external force when the touch display screen 2 is fixed, and the problem of the cover plate glass of the touch display screen 2 being extruded and broken can be avoided, thereby providing effective safety protection for the driver.

[0052] Figure 5 A structural schematic diagram of a touch display screen provided by an embodiment of the present disclosure, Figure 6 A display schematic diagram of a display area provided by an embodiment of the present disclosure. Optionally, in combination with Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the touch display screen 2 includes a touch area 21 and a display area 22. The area of the touch area 21 is greater than the area of the display area 22, and the touch area 21 covers the display area 22. Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The entire area of the touch display screen shown is the touch area 21, and the touch area 21 is integrated with a touch structure, such as a touch electrode, to realize the touch control function of the touch display screen 2. The display area 22 is arranged in a rectangular shape, and the width-length ratio of the display area 22 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 22 is the dimension of the display area 22 along the arrangement direction of the first mounting position 11 and the second mounting position 5.

[0053] Specifically, in combination with Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the touch display screen 2 can include a touch area 21 and a display area 22. The area of the touch area 21 is set to be greater than the area of the display area 22, and the touch area 21 covers the display area 22. The display area 22 can be used to display the content for realizing the human-vehicle interaction. The driver can control the vehicle to perform the corresponding operation by touching the touch area 21 corresponding to the display area 22. The part of the touch area 21 beyond the display area 22 is a reserved area. According to the use demand of the vehicle, elements such as an icon controller can be added to the reserved area, for example, a media controller, a navigation controller, a restart controller, and a volume controller, to meet the diversification and flexibility of the human-vehicle interaction function.

[0054] The touch area 21 can include a touch structure separately arranged from the device in the display area 22, or can be a touch structure integrated with the display screen and simultaneously manufactured in the manufacturing process of the display area 22. For example, the touch area 21 can be in a touch mode of OGS (One Glass Solution), in-cell, on-cell, or GFF (Glass Film Film), and the touch area 21 and the display area 22 can be attached together by using double-sided adhesive, foam, or transparent adhesive, so as to achieve the effect of integration of touch and display, and reduce internal reflection between the touch area 21 and the display area 22, and optimize the display effect of the touch display screen.

[0055] Specifically, the display area 22 can be arranged in a substantially rectangular shape, for example, the four corners of the display area 22 are arranged as rounded corners in Figure 1 、 Figure 2 and Figure 5 . For example, the four corners can be designed as rounded corners with a radius of 2.0 mm, so that the display area 22 effectively matches the overall smooth appearance of the vehicle steering wheel 3, and the appearance of the vehicle is improved. The width-to-length ratio of the display area 22 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 22 is the size of the display area 22 along the arrangement direction of the first mounting position 11 and the second mounting position 5, Figure 5 wherein L represents the length of the display area 22, and W represents the width of the display area 22, i.e., W:L is equal to 1:N. The touch display screen 2 can use a 4.8-inch LCD (Liquid Crystal Display) technology, and the size of the display area 22 can be 120*24 mm, i.e., the width is 24 mm and the length is 120 mm, and 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 22 can be 1:5, which meets the unique 1:5 golden display ratio of the steering wheel 3 structure, and is beneficial to the array layout of the interactive icon pattern 224. Therefore, by arranging the display area 22 in a substantially rectangular shape and arranging the width-to-length ratio of the display area 22 to be equal to 1:N, the multifunctional system integration of the narrow structure area of the vehicle steering wheel 3 is met, including display, touch, software system, horn system, vehicle airbag, and the like, and the display airbag of the arrayed interactive icon pattern 224 of the touch display screen 2 is beneficial, and the display effect of the touch display screen 2 is improved.

[0056] In addition, in combination with Figures 1 to 6When the touch display screen 2 uses non-actively light-emitting electronic devices, such as a liquid crystal display (LCD), the touch display screen 2 must rely on the backlight structure 222 to achieve its display performance. Therefore, the brightness and display content of the touch display screen 2 can be determined by the backlight structure 222. The backlight structure 222 is located on the side of the touch display screen 2 adjacent to the display control circuit board. The backlight structure 222 may include, for example, Figure 5 The matrix arrangement of MiniLED223 (Mini Light Emitting Diode) within the display area 22, as shown, achieves local dimming within a smaller area through a large number of densely packed cells. This results in better brightness uniformity, higher color contrast, and higher brightness within a smaller mixing distance, achieving a contrast ratio of 1,000,000:1, which is 1,000 times higher than the 1,000:1 contrast ratio of ordinary touch screens. The MiniLED223 is powered on and illuminated in the area containing the interactive icon pattern 224 that needs to be lit, while it is powered off and turned off in other areas that do not require display. The unlit areas appear black, thus avoiding screen glare during nighttime driving, providing drivers with comfortable screen brightness, and improving user experience and driving safety.

[0057] Combination Figure 5 and Figure 6 For example, when it is necessary to display an interactive icon pattern for parking on the touch screen 2 on the vehicle steering wheel 3, the MiniLED 223 set in the parking interactive icon display area 221 can be lit up, while the MiniLED 223 set in the display area 22 other than the parking interactive icon display area 221 is turned off. That is, the area other than the parking interactive icon display area 221 is displayed as black. Thus, the touch screen 2 can be integrated with the surrounding environment, optimizing the visual effect of the in-vehicle display device.

[0058] In the prior art, the backlight structure 222 corresponding to the display area 22 is usually of two types: edge-lit backlight structure 222 and direct-lit backlight structure 222. In the edge-lit backlight structure 222, less than half of the light emitted by the light source can often be emitted from the light-emitting surface of the display area 22, resulting in low light emission efficiency, high power consumption, and poor display brightness and uniformity of the corresponding display area 22. The embodiment of this disclosure uses a direct-lit MiniLED 223. The light emitted by the MiniLED 223 can directly illuminate the display area 22 and be emitted from the light-emitting surface, which has higher light emission efficiency and better uniformity than the edge-lit MiniLED 223.

[0059] Figure 5 and Figure 6The example illustrates a display area 22 comprising three interactive icon display areas 221. To ensure a more orderly arrangement of the interactive icon display areas 221, multiple interactive display areas 221 are arranged in a matrix within the display area 22. The length and width of the matrix of interactive display areas 221 can be set according to the shape and size of the interactive icon patterns. Interactive icon patterns are displayed within the interactive icon display areas 221 according to the driver's needs. Interactive icon display areas 221 with proximity functionality are arranged adjacent to each other; for example, the interactive icon display area 221 representing music can be arranged adjacent to the interactive icon display area 221 representing volume. The distance between adjacent interactive icon display areas 221 can be set according to the size of the touch screen 2. It should be noted that the number of matrix interactive icon display areas 221 in this embodiment is not limited, but is set by the size of the touch screen 2 and the usage requirements.

[0060] This embodiment of the present invention features a trapezoidal large arc structure on the upper left and right sides of the cover structure 23 of the touch display screen 2, and the upper and lower edges are designed as arc-shaped R-corner structures. It matches the deformable inclined wall structure of the decorative part 1 and the plastic double-sided adhesive fixing structure. This can solve the risk of glass breakage of the cover structure 23 of the touch display screen 2 in traffic accident scenarios where the steering wheel is involved in a collision. It can make the cover structure 23 slide out of the bracket as a whole under external pressure, avoiding the risk of breakage of the cover structure 23, and effectively integrating the appearance design and electronic structure function airbag.
