Background Art

[0002] With the rapid development of smart cockpits, automakers are paying more and more attention to the riding experience of rear passengers, and have placed rear entertainment screens on the back of the front seats of high-end models to meet the needs of rear passengers.

[0003] In the related art, the male end of some mounting brackets does not comply with the regulations on protruding objects on passenger cars, which can easily cause injury to passengers in the event of a collision or sudden braking. The male end of the bracket protrudes far beyond the seat, encroaching on the rear space and hindering passenger activities. Therefore, it is required to pull out the bracket every time the tablet is used, which is troublesome to operate. After the screen is installed on the mounting bracket, more rear space is occupied, resulting in a larger overall size, which is not convenient for layout of various models. Summary of the Invention

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0069] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0070] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0071] Reference below Figures 1-21 A screen mounting assembly 102 according to an embodiment of the present invention is described. The screen mounting assembly 102 can reduce the distance that the mounting bracket 2 protrudes relative to the seat 100, complies with the requirements of vehicle regulations, and will not cause harm to passengers. The mounting bracket 2 can be installed on the seat 100 for a long time. After being installed in conjunction with the display screen 3, the thickness of the screen mounting assembly 102 is reduced, and the space occupied in the rear row is reduced, and it has a wide range of applications.

[0072] like Figures 1-21 As shown, a screen mounting assembly 102 according to an embodiment of the present invention includes: a mounting base 1 , a mounting bracket 2 and a display screen 3 .

[0073] The mounting base 1 is the installation foundation of the entire screen mounting assembly 102, and is used to support and secure the mounting bracket 2 and the display screen 3. The mounting base 1 is adapted to be embedded in the part to be mounted, that is, mounting holes can be provided on the part to be mounted so that the mounting base 1 can be mounted on the part to be mounted. After installation, the mounting base 1 can be flush with the surface of the part to be mounted, thereby reducing the space occupied by the mounting base 1. For example, when the part to be mounted is a vehicle seat 100, the mounting base 1 can be installed on the rear side of the vehicle seat 100, that is, corresponding mounting holes can be provided on the rear side of the seat 100, and the mounting base 1 can be installed in the mounting holes to securely mount the mounting base 1 on the seat 100. Of course, the mounting base 1 can also be installed in other locations where the screen mounting assembly 102 is required to meet customer needs.

[0074] The mounting bracket 2 is connected to the mounting base 1 along a first direction, and the mounting bracket 2 is used to be connected to the display screen 3 along the first direction.

[0075] Specifically, the display screen 3 can display images and video information, etc., to achieve interaction with the user. The mounting bracket 2 is respectively connected to the mounting base 1 and the display screen 3, and is used to support and fix the display screen 3. The first direction is the connection direction of the mounting bracket 2 and the display screen 3. When the mounting bracket 2 and the display screen 3 are connected along the front and rear direction of the vehicle, the first direction is the front and rear direction, that is, the display screen 3 can be installed on the front side or rear side of the mounting bracket 2.

[0076] Furthermore, at least a portion of the projections of the mounting bracket 2 and the mounting base 1 in the second direction overlap, and the second direction intersects with the first direction.

[0077] Specifically, the first direction may or may not intersect the second direction perpendicularly. When the first direction is the front-to-back direction, the second direction may be a direction perpendicular to the front-to-back direction, such as the left-to-right direction, the up-to-down direction, or other directions. At least a portion of the projections of the mounting bracket 2 and the mounting base 1 in the second direction overlap, i.e., a portion of the mounting bracket 2 overlaps a portion of the mounting base 1 in a direction perpendicular to the connection direction. In other words, the mounting bracket 2 may partially cover the mounting base 1, such that the two overlap when viewed from the second direction.

[0078] Thus, after the display screen 3 is installed, the mounting bracket 2 is partially concealed within the mounting base 1, not fully exposed. This reduces the size and space occupied by the mounting bracket 2, significantly shortens the installation distance between the mounting base 1 and the display screen 3, improves the compactness and stability of the overall structure of the screen mounting assembly 102, and reduces the space occupied by the rear seats. Furthermore, because the mounting bracket 2 is partially hidden, when the display screen 3 is not installed, the distance the mounting bracket 2 protrudes from the seat 100 is very small, complying with passenger regulations and posing no risk to passengers. The mounting bracket 2 can be permanently installed on the seat 100, meaning it does not need to be removed after each use, thus improving ease of use and safety.

[0079] According to the screen mounting assembly 102 of an embodiment of the present invention, the mounting bracket 2 is partially hidden and installed in a part of the mounting base 1, so that the mounting bracket 2 is not completely exposed, thereby reducing the size and occupied space of the mounting bracket 2, reducing the occupation of the rear space, and the protrusion distance of the mounting bracket 2 relative to the seat 100 is very small, which meets the requirements of the riding regulations and will not cause harm to the passengers. The mounting bracket 2 can be installed on the seat 100 for a long time. After being installed in conjunction with the display screen 3, the thickness of the screen mounting assembly 102 is reduced, further reducing the impact on the rear space, and has a wide range of applications.

[0080] In some embodiments, one of the mounting base 1 and the mounting bracket 2 is provided with a mounting groove 11 open along a first direction and the other is provided with a mounting portion 21, which extends into the mounting groove 11 and overlaps with one of the mounting base 1 and the mounting bracket 2 along a second direction.

[0081] That is to say, a mounting groove 11 open along the first direction can be provided on the mounting base 1, and a mounting portion 21 can be provided on the mounting bracket 2, the mounting portion 21 extends into the mounting groove 11 and overlaps with the mounting base 1 along the second direction; or, the mounting portion 21 can be provided on the mounting base 1, and a mounting groove 11 open along the first direction can be provided on the mounting bracket 2, the mounting portion 21 extends into the mounting groove 11 and overlaps with the mounting bracket 2 along the second direction.

[0082] Specifically, if Figure 2 and Figure 3As shown, the first direction can be the front-to-back direction of the seat 100 or the vehicle, i.e., the connection direction between the mounting base 1 and the mounting bracket 2. The mounting base 1 is formed with a mounting groove 11 that is open along the first direction. Specifically, the mounting base 1 is recessed to form the mounting groove 11 that is open toward the mounting bracket 2. The mounting groove 11 is used to accommodate and secure the mounting bracket 2, ensuring that the mounting bracket 2 is securely connected to the mounting base 1, thereby ensuring the installation stability of the display screen 3. In an actual design, the mounting base 1 can be constructed in a thin, round, pancake shape so that, after being installed on the seat 100, the mounting base 1 is substantially flush with the surface of the seat 100, reducing the space occupied in the rear row and facilitating its installation on the seats 100 of various vehicle models.

[0083] The mounting bracket 2 is provided with a mounting portion 21, which is arranged toward the mounting base 1. The size and shape of the mounting portion 21 are adapted to the size and shape of the mounting groove 11, so that the mounting portion 21 can extend into the mounting groove 11 and overlap with the mounting base 1 in the second direction, that is, the mounting portion 21 is hidden in the mounting groove 11, thereby reducing the space occupied by the mounting bracket 2 in the rear row.

[0084] In some embodiments, the mounting base 1 is formed with a mounting groove 11; wherein, the mounting bracket 2 includes a connected mounting portion 21 and a accommodating portion 22, the accommodating portion 22 is located outside the mounting groove 11, and the accommodating portion 22 is formed with a accommodating groove 221 open along a first direction on a side facing away from the mounting base 1, and the accommodating groove 221 is used to accommodate at least a portion of the display screen 3.

[0085] Specifically, if Figure 2 and Figure 3 As shown, the mounting base 1 is formed with a mounting groove 11, and the mounting bracket 2 includes a mounting portion 21 and a receiving portion 22, and the mounting portion 21 and the receiving portion 22 are fixedly connected and can be integrated in an integrated manufacturing process so that the mounting portion 21 and the receiving portion 22 can be connected into an integral structure, which is not only convenient for manufacturing, but also improves the connection reliability and stability of the mounting portion 21 and the receiving portion 22.

[0086] The accommodating portion 22 is located outside the mounting groove 11, and a receiving groove 221 is formed on the side of the accommodating portion 22 facing away from the mounting base 1. The receiving groove 221 is used to accommodate at least a portion of the display screen 3. In other words, the accommodating portion 22 is used to directly support and secure the display screen 3. The side of the accommodating portion 22 facing away from the mounting base 1, that is, the side facing the display screen 3, is recessed a certain distance to form the receiving groove 221. A portion of the display screen 3 can extend into the receiving groove 221. In actual design, the accommodating portion 22 and the display screen 3 can be adjusted within a certain range, thereby achieving stable installation of the display screen 3.

[0087] In an actual design, the mounting portion 21 can be configured to be removably mounted within the mounting groove 11. That is, the mounting portion 21 is used to be fixedly connected to the mounting base 1. The mounting portion 21 should match the mounting groove 11 of the mounting base 1 and can be installed on the mounting base 1 through a removable connection method such as a bolt connection or a snap connection, and extend into the mounting groove 11 to achieve fixed installation of the mounting portion 21 on the mounting base 1. The removable connection between the mounting groove 11 and the mounting portion 21 improves the convenience of connecting and disassembling the mounting base 1 and the mounting bracket 2. That is, when the mounting bracket 2 or display screen 3 is not in use, the mounting bracket 2 can be removed, saving space in the rear row, facilitating replacement and maintenance, and providing flexible and convenient operation.

[0088] It should be noted that after the mounting portion 21 is installed in the mounting groove 11, it can be hidden in the mounting base 1, thereby reducing the space occupied by the mounting bracket 2 in the back row. The mounting bracket 2 can be designed as an overall ultra-thin structure, especially the accommodating portion 22 exposed to the mounting base 1, which can be made ultra-thin. In this way, it not only avoids causing harm to passengers, but also avoids encroaching on the back row space. When the display screen 3 is not installed, the distance that the accommodating portion 22 protrudes relative to the seat 100 is very small, which meets the requirements of the regulations on protruding objects in the vehicle and will not cause harm to passengers. The mounting bracket 2 can be installed on the seat 100 for a long time, that is, there is no need to pull out the mounting bracket 2 every time after use, which improves the convenience and safety of use.

[0089] In some embodiments, a movable cover 111 is provided in the mounting slot 11, and the cover 111 can be covered on the mounting slot 11 to close the mounting slot 11. In this way, when the mounting bracket 2 and the display screen 3 are not in use, external dust and the like can be prevented from entering the mounting slot 11 to keep the inside of the mounting slot 11 clean. At the same time, the cover 111 can move in the mounting slot 11, thereby providing a controllable opening for the mounting part 21 to enter the mounting slot 11. In other words, the cover 111 can be controlled to move flexibly at the opening of the mounting slot 11 to achieve the installation of the mounting part 21 in the mounting slot 11.

[0090] Furthermore, a first elastic member 12 is provided between the cover 111 and the mounting base 1. The first elastic member has an elastic telescopic force and can undergo a certain elastic deformation. The first elastic member 12 can be constructed as a spring, an elastic rubber sheet or other elastic element. The first elastic member 12 is used to push the cover 111 to move to a position where the mounting slot 11 is closed, and the mounting portion 21 is suitable for pushing the cover 111 to move to a position where the mounting slot 11 is opened. In other words, the movement of the cover 111 within the accommodating slot 221 can be achieved by utilizing the elastic telescopic force of the first elastic member 12. The first elastic member 12 needs to enable the cover 111 to tightly close the mounting slot 11 when there is no external force pushing the cover 111, and can also enable the cover 111 to move to a position where the mounting slot 11 is opened when the mounting portion 21 pushes the cover 111 to move.

[0091] Specifically, if Figure 2 As shown, the base is provided with a mounting groove 11. The mounting groove 11 is constructed in a hollow cylindrical shape and is relatively large in size. In this way, when the user installs the mounting bracket 2 on the mounting base 1, there is no risk of pinching the hand, thereby improving the safety of use. A cover plate 111 is provided in the mounting groove 11. The cover plate 111 is constructed in a disc shape and its size is adapted to the size of the mounting groove 11. Thus, it can be covered on the mounting groove 11 to close the mounting groove 11 and can move in the mounting groove 11, as shown in FIG. Figure 11 As shown, a first elastic member 12 is provided between the bottom wall of the mounting groove 11 and the cover plate 111. The first elastic member 12 is elastically pressed between the bottom wall of the mounting groove 11 and the cover plate 111. When the mounting bracket 2 is not installed, the cover plate 111 is elastically pushed by the first elastic member 12 to be flush with the outer surface of the mounting base 1.

[0092] During the actual installation process, when the mounting portion 21 enters the mounting groove 11, it contacts the cover plate 111 and pushes the cover plate 111 to overcome the elastic force of the first elastic member 12 and open the opening of the mounting groove 11. At this time, the first elastic member 12 is compressed and the cover plate 111 moves toward the mounting groove 11, which corresponds to Figure 11 , the cover 111 moves to the left in the direction shown in the figure until the cover 111 moves to press against the bottom wall of the mounting groove 11. At this time, the mounting portion 21 is completely installed in the mounting groove 11, and the mounting portion 21 is fixedly installed in the mounting groove 11. When the mounting bracket 2 is removed from the mounting base 1, the cover 111 can move in the direction away from the mounting groove 11 under the thrust of the first elastic member 12, which corresponds to Figure 11 The first elastic member 12 moves rightward in the direction shown in FIG, until the cover plate 111 moves to reclose the mounting groove 11, at which time, the first elastic member 12 returns to its initial state.

[0093] Therefore, through the setting of the first elastic member 12, the installation portion 21 can easily push the cover 111 to open the installation slot 11, which simplifies the installation process. After the installation is completed, the cover 111 automatically closes the installation slot 11 without the need for additional operation. The operation is simple and quick, and there is no safety risk in use. The movement of the cover 111 does not require the design of a switch, and the structure is simple, the cost is low, and the reliability is high.

[0094] In some embodiments, as Figure 2 As shown, the mounting base 1 is provided with an electric control board 13 and a conductive plate 14, and the mounting bracket 2 is provided with an electrical adapter 23. The electric control board 13 is an electrical connection element in the screen mounting assembly 102. The electric control board 13 can be constructed as a PCB board. The conductive plate 14 is used to realize the electrical connection between the electric control board 13 and the electric adapter 23. The electric adapter 23 can transmit the signal from the electric control board 13 to the display screen 3 to ensure the normal use of the display screen 3.

[0095] When the mounting portion 21 pushes the cover plate 111, it moves the conductive plate 14, causing the conductive plate 14 to electrically connect the electric control board 13 to the electrical adapter 23. In other words, when the mounting bracket 2 is mounted on the mounting base 1, the mounting portion 21 pushes the cover plate 111 toward the mounting slot 11, which in turn drives the conductive plate 14 to move, causing the conductive plate 14 to simultaneously contact and connect with the electric control board 13 and the electrical adapter 23, thereby achieving electrical connection between the electric control board 13 and the electrical adapter 23.

[0096] Thus, the installation portion 21 pushes the cover plate 111 to move, thereby driving the conductive plate 14 to move so that the conductive plate 14 can contact and connect with the electric control board 13 and the electric adapter 23, thereby realizing automatic electrical connection between the electric control board 13 and the electric adapter 23, thereby improving the installation efficiency and the accuracy and reliability of the electrical connection.

[0097] In actual design, the conductive plate 14 can be set to any conductive metal or alloy plate that can achieve conductivity.

[0098] In some embodiments, as Figure 5 and Figure 11 As shown, the electric control board 13 is provided with a conductive spring 131. The conductive spring 131 is a cantilever beam type. One end is a fixed end, which can be passed through the conductive hole on the electric control board 13 and fixed to the electric control board 13 by welding. The other end is a free end, which extends out of the electric control board 13 and can be movable. The thickness of the conductive spring 131 can be set to be relatively thin, which is easy to elastically deform and can ensure that a reliable electrical connection is maintained under vibration conditions. Figure 11As shown, the conductive plate 14 is constructed in a bent shape. The conductive plate 14 includes a first plate portion 141, a rotating portion 142 and a second plate portion 143. As shown in the left and right directions in the figure, the first plate portion 141 is the plate portion at the left end, the second plate portion 143 is the plate portion at the right end, and the rotating portion 142 is the middle portion. The first plate portion 141 and the second plate portion 143 are connected by bending at a certain angle through the rotating portion 142. The surface of the first plate portion 141 is flat, and the surface of the second plate portion 143 is uneven.

[0099] Furthermore, the rotating portion 142 is rotatably mounted on the mounting base 1 via a rotating shaft 144, the first plate portion 141 and the second plate portion 143 are respectively connected to the rotating portion 142, the first plate portion 141 and the second plate portion 143 are distributed at an obtuse angle, and the cover plate 111 is suitable for pushing the first plate portion 141 against the conductive spring sheet 131 while pressing the second plate portion 143 against the electrical adapter 23.

[0100] That is, the rotating portion 142 is provided with a rotating shaft 144 hole, and the rotating shaft 144 can be inserted into the rotating shaft 144 hole, so that the rotating portion 142 can be rotated relative to the mounting base 1 through the rotating shaft 144. Figure 11 and Figure 13 As shown, the right end of the first plate portion 141 is fixedly connected to the rotating portion 142, and the left end of the second plate portion 143 is fixedly connected to the rotating portion 142. Thus, the first plate portion 141, the second plate portion 143, and the rotating portion 142 are connected as a whole. When the rotating portion 142 rotates about the rotating axis 144, the rotating portion 142 can drive the first and second plate portions 141, 143 to move. In other words, the conductive plate 14 can act like a "seesaw." When the rotating portion 142 rotates in one direction, the first plate portion 141 moves upward while the second plate portion 143 moves downward. When the rotating portion 142 rotates in the opposite direction, the first plate portion 141 moves downward while the second plate portion 143 moves upward. Furthermore, the first plate portion 141 and the second plate portion 143 are arranged at an obtuse angle, which facilitates contact and connection between the electrical control board 13 and the electrical adapter 23.

[0101] During the actual installation process, Figure 11 As shown, in the initial state, the first plate portion 141 of the conductive sheet extends obliquely downward, and its height is slightly lower than the height of the lower side of the cover plate 111. The conductive spring 131 does not deform, and its free end presses horizontally against the first plate portion 141, so that the conductive spring 131 contacts and maintains electrical connection with the conductive plate 14. The second plate portion 143 of the conductive sheet extends horizontally, and its height is slightly higher than the height of the lower side of the cover plate 111. During the installation of the mounting portion 21 in the mounting slot 11, as shown in FIG. Figure 13 and Figure 15As shown, when the mounting portion 21 pushes the cover plate 111 toward the mounting groove 11, since the height of the second plate portion 143 is slightly higher than the height of the lower side of the cover plate 111, the second plate portion 143 does not hinder the movement of the cover plate 111. When the cover plate 111 continues to move toward the mounting groove 11, that is, moves to the left, the cover plate 111 will touch the first plate portion 141 and lift the first plate portion 141 upward. At this time, the rotating portion 142 will rotate clockwise (as shown in the direction in the figure). When the first plate portion 141 is lifted, the free end of the conductive spring 131, that is, the right end in the figure, is lifted to cause it to elastically deform. The second plate portion 143 will move downward to contact and connect with the electrical adapter 23, thereby realizing the electrical connection between the conductive plate 14 and the electrical adapter 23. As a result, the two ends of the conductive plate, that is, the first plate portion 141 and the second plate portion 143, are simultaneously in contact and connected with the conductive spring 131 and the electrical adapter 23, thereby realizing the electrical connection between the electric control board 13 and the electrical adapter 23.

[0102] When the mounting bracket 2 is actually disassembled, that is, when the mounting portion 21 is pulled out of the mounting slot 11, the cover plate 111 can move to the right under the thrust of the first elastic member 12 until it is flush with the outer surface of the mounting base 1 and closes the mounting slot 11. At the same time, the conductive spring piece 131 will restore its horizontal and straight state and press the first plate portion 141 downward, the rotating portion 142 will rotate counterclockwise (as shown in the direction in the figure), the second plate portion 143 will be lifted upward, and each component will return to its initial state.

[0103] In some embodiments, as Figure 12 As shown, the second plate portion 143 includes a weakened area 1431 and a conductive area 1432. The conductive area 1432 is used to achieve electrical connection with the electrical adapter 23. The weakened area 1431 makes the second plate portion 143 easy to elastically deform, so as to facilitate a stable and reliable electrical connection between the conductive area 1432 and the electrical adapter 23, and maintain a reliable electrical connection even under vibration conditions.

[0104] The weakened region 1431 is connected between the rotating portion 142 and the conductive region 1432. The thickness of the weakened region 1431 is thinner than that of the first plate portion 141, making the weakened region 1431 thinner and more susceptible to elastic deformation. The conductive region 1432 is formed with a conductive convex surface 14321, which is adapted to press against the electrical adapter 23 to establish an electrical connection between the conductive plate 14 and the electrical adapter 23. In an actual design, the conductive convex surface 14321 can be constructed as a hemispherical shape and can be thicker than the first plate portion 141 and the weakened region 1431. This facilitates press against the electrical adapter 23.

[0105] During the actual installation process, Figure 5 As shown, the electrical adapter 23 is constructed as a "T"-shaped structure. Figure 14As shown, when the mounting portion 21 pushes the cover 111 to move toward the mounting slot 11, the conductive convex surface 14321 will touch and press the electrical adapter 23 during the downward movement of the second plate portion 143. When the cover 111 moves to the bottom of the mounting slot 11, the right end of the first plate portion 141 and the conductive spring 131 will be lifted to the highest point, and the rotating portion 142 will rotate clockwise. However, the conductive convex surface 14321 cannot continue to move downward due to the pressing contact with the upper surface of the electrical adapter 23, so the weakened area 1431 will undergo bending elastic deformation. In this way, a reliable electrical connection can be maintained under vibration conditions, thereby ensuring stable signal transmission.

[0106] In some embodiments, there are multiple conductive plates 14 and conductive spring clips 131, that is, the number of conductive plates 14 and conductive spring clips 131 can be set to two, three, four or even more, and the multiple conductive plates 14 are matched with the multiple conductive spring clips 131 in a one-to-one manner, and the multiple conductive spring clips 131 are distributed and spaced apart in the horizontal direction. In this way, the conductive plates 14 and the conductive spring clips 131 are evenly distributed and correspondingly connected, which can improve the electrical connection reliability and stability of the conductive plates 14 and the conductive spring clips 131. When one of the conductive plates 14 or the conductive spring clips 131 is damaged, the other conductive plates 14 and the conductive spring clips 131 can still maintain a reliable electrical connection, thereby avoiding affecting the signal transmission from the electronic control board 13 to the display screen 3 and affecting the use of the display screen 3.

[0107] Specifically, if Figure 2 As shown, five conductive springs 131 are provided on the electric control board 13 and are evenly distributed and spaced apart in the horizontal direction. Five conductive plates 14 are provided in the mounting base 1 and are evenly distributed and spaced apart in the horizontal direction. The five conductive springs 131 are connected to the five corresponding ones one by one. Therefore, when the cover plate 111 moves, the first plate portion 141 and the second plate portion 143 can be pushed to move at the same time, ensuring that each conductive plate 14 can be reliably connected to the conductive spring 131 and the electrical adapter 23.

[0108] In some embodiments, a plug-in protrusion 112 is provided in the installation groove 11, the cover plate 111 is arranged around the plug-in protrusion 112, and the cover plate 111 is formed with an avoidance opening 1112 for avoiding the plug-in protrusion 112, and the installation portion 21 is formed with a plug-in recess 212, and the plug-in protrusion 112 is plugged into and matched with the plug-in recess 212.

[0109] Specifically, if Figure 2As shown, a plug-in protrusion 112 is provided in the middle of the mounting groove 11, and the plug-in protrusion 112 is constructed in a rectangular shape. A USB socket 52 is connected to the electronic control board 13, and the USB socket 52 is adapted to the shape and size of the plug-in protrusion 112, so that the USB socket 52 can be inserted into the plug-in protrusion 112, and a corresponding avoidance opening 1112 for avoiding the plug-in protrusion 112 is provided in the middle of the cover plate 111. The avoidance opening 1112 is constructed as a rectangular hole, that is, the plug-in protrusion 112 can pass through the avoidance opening 1112 and be flush with the outside of the mounting base 1. In this way, the USB socket 52 can be inserted into the plug-in protrusion 112 and extend to the avoidance opening 1112. When the base 1 is not installed and the bracket 2 is not installed, the user can use the USB socket 52 for charging, which expands the scope of use of the mounting base 1. In other words, the mounting base 1 is not only used to provide an installation and communication interface for the display screen 3, but also provides a USB charging function, which greatly improves the convenience of use. In actual design, the plug-in protrusion 112 and the avoidance opening 1112 can be configured to be clearance-fitted.

[0110] Among them, such as Figure 4 As shown, a plugging recess 212 is provided in the middle of the mounting portion 21. The plugging recess 212 is adapted to the shape of the plugging protrusion 112. The size of the plugging recess 212 can be designed to be slightly larger than the size of the plugging protrusion 112, so that the plugging protrusion 112 can be inserted into the plugging recess 212, achieving plug-fitting between the plugging protrusion 112 and the plugging recess 212. In actual design, the plugging protrusion 112 and the plugging recess 212 can be set to a clearance fit.

[0111] In some embodiments, a light guide 15 is further provided in the mounting base 1 . The light guide 15 is formed with an annular light guide ring 151 . The annular light guide ring 151 is extended along the circumference of the plug-in protrusion 112 .

[0112] Specifically, if Figure 2 As shown, a light guide 15 is provided in the mounting base 1, and the light guide 15 forms an annular light guide ring 151. The annular light guide ring 151 can be extended along the circumference of the plug-in protrusion 112 and sleeved on the outside of the USB socket 52. A light source can be provided on the electronic control board 13. The light guide 15 can distribute the light emitted by the light source to the annular light guide ring 151. After receiving the light emitted by the light source, the annular light guide ring 151 emits the light evenly, so that the light can surround the USB socket 52 to form a soft and uniform lighting effect, thereby realizing the illumination of the USB socket 52. In this way, it is convenient for users to insert the USB socket 52 for charging in a dark environment, thereby improving the convenience of use.

[0113] In some embodiments, the cover 111 is provided with a guide column 1111 , the mounting base 1 is provided with a guide hole 16 , the guide column 1111 extends into the guide hole 16 and moves along the guide hole 16 , and the first elastic member 12 is sleeved outside the guide column 1111 .

[0114] Specifically, if Figure 2 As shown, a guide post 1111 is provided on the side of the cover plate 111 facing the mounting groove 11. The guide post 1111 is used to guide the movement of the first elastic member 12 and the cover plate 111, ensuring that the first elastic member 12 and the cover plate 111 can move smoothly along a predetermined path, that is, in the left and right directions in the figure, to prevent deviation or shaking. One end of the guide post 1111 can be connected to the cover plate 111 by welding, or can be designed as an integral part of the cover plate 111. A guide hole 16 is provided on the mounting base 1. The position and size of the guide post 1111 match the guide hole 16, so that the other end of the guide post 1111 can be smoothly inserted into the guide hole 16 and can move along the guide hole 16. The provision of the guide hole 16 ensures the linear movement of the guide post 1111 and also limits the movement of the guide post 1111 perpendicular to the direction of movement, thereby increasing the stability of the structure.

[0115] Among them, such as Figure 11 As shown, the first elastic member 12 is sleeved outside the guide column 1111 and pressed between the cover plate 111 and the mounting base 1. In this way, the first elastic member 12 can perform telescopic movement along the extension direction of the guide column 1111, thereby ensuring the reliability of the first elastic member 12.

[0116] In some embodiments, there are multiple guide posts 1111, that is, the number of guide posts 1111 can be set to two, three, or even more. Multiple guide posts 1111 can effectively disperse the force and torque generated by the cover plate 111 during movement, making the entire movement process smoother and reducing the load borne by a single guide post 1111. There are multiple first elastic members 12, and they are mounted one-to-one on the outside of the multiple guide posts 1111, that is, the number of first elastic members 12 corresponds to the number of guide posts 1111. It can also be set to two, three, or even more, and multiple first elastic members 12 are mounted one-to-one on the outside of the multiple guide posts 1111. The multiple first elastic members 12 can ensure that the cover plate 111 as a whole can move to a position that closes the mounting slot 11 under the thrust of the first elastic members 12, thereby ensuring the structural stability of the cover plate 111.

[0117] In this way, by providing multiple guide posts 1111 and multiple first elastic members 12 , reliable and smooth movement of the cover 111 is ensured, and effective movement of the cover 111 is ensured even when one guide post 1111 or the first elastic member 12 is damaged.

[0118] Specifically, if Figure 2As shown, four guide columns 1111 are provided on the cover plate 111, and the four guide columns 1111 are evenly arranged along the periphery of the cover plate 111. Four guide holes 16 are correspondingly provided on the mounting base 1, and the four guide holes 16 are also evenly arranged along the periphery of the mounting base 1. The four first elastic members 12 are correspondingly sleeved on the outside of the guide columns 1111.

[0119] In some embodiments, the mounting portion 21 is provided with a radially movable locking tongue structure 211 , and the inner peripheral wall of the mounting groove 11 is provided with a locking opening 113 . The locking tongue structure 211 is adapted to be snapped into the locking opening 113 along the radial direction of the mounting portion 21 .

[0120] Specifically, if Figure 3-Figure 5 As shown, the mounting portion 21 is provided with a radially movable locking tongue structure 211 . When unlocked, the locking tongue structure 211 protrudes from the periphery of the mounting portion 21 , so that the user can manually press the locking tongue structure 211 . The locking hole 113 is provided on the inner peripheral wall of the mounting groove 11. The locking hole 113 is adapted to the shape and size of the locking tongue structure 211 and corresponds in position, so that the locking tongue structure 211 can be tightly and firmly engaged in the locking hole 113 of the mounting groove 11. After the locking tongue of the locking tongue structure 211 is pressed into the interior of the mounting portion 21, when the user needs to engage and lock it with the mounting bracket 2, the user can manually release the locking tongue structure 211. The locking tongue structure 211 extends radially and engages in the locking hole 113, thereby moving from an unlocked position (for example, a position inside or close to the interior of the mounting portion 21) to a locked position (that is, a position aligned and engaged with the locking hole 113 of the mounting groove 11), thereby realizing the engagement and locking of the mounting base 1 and the mounting bracket 2 to prevent the two from relative movement or falling off.

[0121] In some embodiments, there are at least two locking tongue structures 211 and at least two locking openings 113 , and the two locking tongue structures 211 are spaced apart and distributed in the circumferential direction of the mounting portion 21 .

[0122] That is to say, the locking tongue structure 211 and the locking opening 113 can be set to two, three, four or more, and the multiple locking tongue structures 211 and the multiple locking openings 113 are matched one by one, and the multiple locking tongue structures 211 are evenly distributed in the circumferential direction of the mounting portion 21. In this way, the mounting portion 21 can be locked with the locking opening 113 at multiple positions, which improves the locking effect and makes the locking process more stable and reliable, thereby improving the stable connection effect between the mounting bracket 2 and the mounting base 1. At the same time, the multiple locking tongue structures 211 can withstand part of the force, thereby reducing the force on a single locking tongue structure 211 and improving the durability and reliability of the locking tongue structure 211. At the same time, the multiple locking tongue structures 211 can effectively prevent the mounting portion 21 from rotating relative to the mounting groove 11, and can achieve precise alignment.

[0123] In some embodiments, the lock tongue structures 211 are distributed in multiple groups, and the multiple groups of lock tongue structures 211 are distributed in sequence in the circumferential direction of the mounting portion 21, wherein each group has two lock tongue structures 211, one lock tongue structure 211 is a hand lock tongue 2111 and the other lock tongue structure 211 is a driven lock tongue 2112, and the hand lock tongue 2111 is suitable for driving the driven lock tongue 2112 to move together relative to the corresponding locking port 113.

[0124] Specifically, multiple groups of locking tongue structures 211 can be provided, which are uniformly distributed in the circumferential direction of the mounting portion 21 to improve the connection stability and reliability between the mounting portion 21 and the mounting groove 11. Figure 6 and Figure 7 As shown, two groups of lock tongue structures 211 are provided, one group of lock tongue structures 211 on the upper side and the right side, and one group of lock tongue structures 211 on the lower side and the left side. There are two lock tongue structures 211 in each group, one is a hand lock tongue 2111 and the other is a driven lock tongue 2112. The two hand lock tongues 2111 of the two groups of lock tongue structures 211 are distributed along the left and right directions respectively, and the two driven lock tongues 2112 are distributed along the up and down directions.

[0125] In practice, when in the unlocked state, the lock tongues of the hand lock tongue 2111 and the driven lock tongue 2112 are both extended outside the mounting portion 21. The user can manually press and push the lock tongue of the hand lock tongue 2111 to move radially inward along the mounting portion 21 and extend into the mounting portion 21. When the hand lock tongue 2111 moves, the lock tongue of the driven lock tongue 2112 is driven to move radially along the mounting portion 21 and extend into the mounting portion 21. When the mounting portion 21 is installed in the mounting groove 11, the user can release the hand lock tongue 2111. 111. At this time, the lock tongue of the hand lock tongue 2111 moves radially outward along the mounting portion 21 and is engaged in the corresponding locking hole 113. At the same time, the hand lock tongue 2111 drives the lock tongue of the driven lock tongue 2112 to move radially outward along the mounting portion 21 and is engaged in the corresponding locking hole 113, thereby realizing the locking. When unlocking is required, the user can press and push the lock tongue of the hand lock tongue 2111 again to move radially inward along the mounting portion 21 to disengage from the locking hole 113, thereby realizing unlocking.

[0126] Therefore, by setting up multiple groups of lock tongue structures 211, the connection strength between the mounting portion 21 and the mounting groove 11 is greatly enhanced, making the connection between the two more stable and reliable. The driven lock tongue 2112 is driven to move by the buckle lock tongue 2111. The user only needs to operate with one hand (pressing the left and right buckle lock tongues 2111 at the same time) to push and release multiple lock tongues at the same time, thereby improving the locking and unlocking efficiency.

[0127] In some embodiments, as Figure 5 As shown, a second elastic member 41 is provided between the buckle lock tongue 2111 and the mounting bracket 2. The second elastic member 41 has a certain elastic stretching force and can be elastically deformed.

[0128] The second elastic member 41 is suitable for pushing the buckle lock tongue 2111 to move radially outward along the mounting portion 21 , and the buckle lock tongue 2111 is suitable for being driven by external force to overcome the elastic force of the second elastic member 41 so as to be received in the mounting portion 21 .

[0129] That is to say, when the buckle lock tongue 2111 is in a natural state, the elastic force of the second elastic member 41 can push the buckle lock tongue 2111 to move radially outward along the mounting portion 21, so that the buckle lock tongue 2111 extends outside the mounting portion 21 and remains in the extended state, thereby maintaining the locked state. When the user manually pushes the buckle lock tongue 2111, that is, the buckle lock tongue 2111 is driven by external force to overcome the elastic force of the second elastic member 41 and move radially inward along the mounting portion 21, so that the buckle lock tongue 2111 is retracted into the mounting portion 21.

[0130] In actual design, the second elastic member 41 can be constructed as a spring.

[0131] In some embodiments, as Figure 6 and Figure 7 As shown, the hand lock tongue 2111 is provided with an active rack portion 21111 extending radially along the mounting portion 21, and the driven lock tongue 2112 is provided with a driven rack portion 21121 extending radially along the mounting portion 21, and the active rack portions 21111 of the two groups of lock tongue structures 211 are staggered along the up and down directions, that is, one active rack portion 21111 is located on the upper side of the hand lock tongue 2111, and the other active rack portion 21111 is located on the lower side of the other hand lock tongue 2111, and the driven lock tongues 2112 of the two groups of lock tongue structures 211 are staggered along the left and right directions, that is, one driven rack portion 21121 is located on the left side of the driven lock tongue 2112, and the other driven rack portion 21121 is located on the lower right side of the other driven lock tongue 2112, so as to facilitate the linkage between the hand lock tongue 2111 and the driven lock tongue 2112.

[0132] like Figure 6 and Figure 7 As shown, a driving gear 42 and a driven gear 43 are provided between the hand lock tongue 2111 and the driven lock tongue 2112 . The driving gear 42 is engaged with the driven gear 43 . The driving gear 42 is engaged with the driving rack portion 21111 , and the driven gear 43 is engaged with the driven rack portion 21121 .

[0133] That is to say, when the hand lock tongue 2111 is in a natural state, the driving gear 42 and the driven gear 43 are in a meshing state, and the entire transmission structure is in a stationary state. When the hand lock tongue 2111 moves radially inward along the mounting portion 21, the driving rack portion 21111 moves to drive the driving gear 42 to rotate, and the driving gear 42 drives the driven gear 43 meshed with it to rotate, and the driven gear 43 then drives the driven rack portion 21121 to move, so that the driven lock tongue 2112 also moves radially inward along the mounting portion 21, thereby ensuring the synchronous movement of the hand lock tongue 2111 and the driven lock tongue 2112, and improving the smoothness and reliability of the locking and unlocking process between the mounting portion 21 and the mounting groove 11.

[0134] In actual design, the driven lock tongue 2112 is also provided with a lock tongue stop surface 51, that is, when the driven lock tongue 2112 moves radially inward along the mounting portion 21 until the lock tongue stop surface 51 contacts the inner wall surface of the mounting portion 21, the movement stops, thereby preventing the lock tongue from extending too deep. Figure 6 and Figure 7 In the direction shown, the widths of the "lock tongues" of the upper and lower driven lock tongues 2112 can be set to different. For example, the upper one is set wider and the lower one is set narrower. The widths of the locking openings 113 on the mounting groove 11 can be set to different accordingly. In this way, if the mounting bracket 2 is inverted on the mounting base 1, the "lock tongue" of the wider driven lock tongue 2112 on the upper side cannot be inserted into the narrower locking opening 113 on the lower side, which can play a fool-proof role, that is, prevent the installation from being inverted.

[0135] In some embodiments, one of the accommodating portion 22 and the display screen 3 is provided with an arcuate female buckle 44 and the other is provided with an arcuate male buckle 45. The arcuate female buckle 44 and the arcuate male buckle 45 are suitable for locking along the circumferential rotation of the display screen 3 to cooperate with the axial limit of the display screen 3.

[0136] That is to say, an arc-shaped female buckle 44 can be provided on the accommodating portion 22, and an arc-shaped male buckle 45 can be provided on the display screen 3, or an arc-shaped male buckle 45 can be provided on the accommodating portion 22, and an arc-shaped female buckle 44 can be provided on the display screen 3. The arc-shaped female buckle 44 can be constructed as an arc-shaped groove or track with a locking surface, and the arc-shaped male buckle 45 can be constructed as an arc-shaped protrusion or bump matching the arc-shaped female buckle 44, so that the arc-shaped male buckle 45 can rotate along the arc-shaped groove or track of the arc-shaped female buckle 44, and will no longer rotate when reaching the locking surface, thereby realizing the circumferential rotation locking and axial limiting cooperation of the arc-shaped female buckle 44 and the arc-shaped male buckle 45 along the display screen 3, thereby realizing stable installation between the display screen 3 and the mounting bracket 2.

[0137] In some embodiments, as Figure 6 and Figure 7As shown, the accommodating portion 22 is provided with a first magnetic member 222, which has magnetic attraction. The first magnetic member 222 is tiltedly arranged on the accommodating portion 22, and the angle between the direction and the axis is 45 degrees as shown in the figure. Two first magnetic members 222 are provided, one is located on the upper left and the other is located on the lower right.

[0138] like Figure 8 and Figure 9 As shown, the display screen 3 is provided with a second magnetic member 311. The second magnetic member 311 also has magnetic attraction and can be attracted to the first magnetic member 222 to facilitate accurate alignment of the display screen 3. The second magnetic member 311 is horizontally arranged on the mating portion 31 along the left and right directions. Two second magnetic members 311 can be provided, one on the left and one on the right, and installed inside the mating portion 31.

[0139] In actual design, both the first magnetic member 222 and the second magnetic member 311 can be constructed as magnets. It should be noted that the arrangement position and direction of the first magnetic member 222 and the second magnetic member 311 can be flexibly adjusted according to actual conditions and are not limited to those described in this embodiment.

[0140] Furthermore, after the arc-shaped male buckle 45 and the arc-shaped female buckle 44 are rotationally locked, the first magnetic member 222 and the second magnetic member 311 are aligned with each other along the axial direction of the display screen 3 and are attracted to each other.

[0141] Specifically, if Figure 9 As shown, when the display screen 3 begins to be installed and aligned with the mounting bracket 2, the display screen 3 needs to be tilted first, that is, in the direction shown in the figure, it is rotated approximately 45 degrees clockwise relative to the horizontal direction (in actual installation, it is rotated approximately 45 degrees counterclockwise from the user's perspective). It should be noted that the approximately 45-degree rotation here does not need to be very accurate. Even if the display screen 3 is rotated approximately only more than 20 degrees, or as high as more than 60 degrees when aligned, due to the attraction of the first magnetic part 222 and the second magnetic part 311, the display screen 3 can be automatically attracted to an inclination of 45 degrees and can be initially tightened. After the display screen 3 is initially tightened, the first magnetic part 222 and the second magnetic part 311 are aligned and attracted along the axis of the display screen 3. The user can manually rotate the display screen 3 so that the arc-shaped male buckle 45 and the arc-shaped female buckle 44 are rotationally locked, as shown in FIG. Figure 8 As shown, at this time, the first magnetic member 222 and the second magnetic member 311 rotate to the horizontal direction, thereby achieving fixed installation of the display screen 3 and the mounting bracket 2.

[0142] In some embodiments, one of the accommodating portion 22 and the display screen 3 is provided with a limiting ball 46 and the other is provided with a spaced arc sliding groove 47 and a circular limiting groove 48, the limiting ball 46 is connected to a third elastic member 49, the third elastic member 49 is used to push the sliding support of the limiting ball 46 in the arc sliding groove 47, and after the arc male buckle 45 and the arc female buckle 44 are rotated and locked, the limiting ball 46 switches to the circular limiting groove 48.

[0143] That is to say, a limiting ball 46 can be provided on the accommodating portion 22, and an arc-shaped sliding groove 47 and a circular limiting groove 48 can be provided on the display screen 3, or an arc-shaped sliding groove 47 and a circular limiting groove 48 can be provided on the accommodating portion 22, and a limiting ball 46 can be provided on the display screen 3, and the arc-shaped sliding groove 47 and the circular limiting groove 48 are spaced apart, and the third elastic member 49 has a certain elastic force, which can push the limiting ball 46 to slide and support in the arc-shaped sliding groove 47, that is, the length of the arc-shaped sliding groove 47 is the sliding displacement of the limiting ball 46, and after the arc-shaped male buckle 45 and the arc-shaped female buckle 44 are rotated and locked, the limiting ball 46 switches to the circular limiting groove 48, that is, the circular limiting groove 48 is the final locking position of the limiting ball 46, which limits the movement of the limiting ball 46 after locking, and avoids the sliding friction stroke of the limiting ball 46 being too long.

[0144] Specifically, if Figures 8-10 As shown, an arc-shaped sliding groove 47 and a circular limiting groove 48 are provided on the upper left side of the middle position of the display screen 3. The circular limiting groove 48 is provided at the right end of the arc-shaped sliding groove 47. The accommodating portion 22 is provided with a limiting ball 46. A third elastic member 49 and a fixing plate 50 are provided on the side of the limiting ball 46 close to the mounting bracket 2. The fixing plate 50 is used to fix the third elastic member 49 and the limiting ball 46, so that one end of the limiting ball 46 is elastically pressed against the third elastic member 49, and under the thrust of the third elastic member 49, it extends out of the bottom surface of the mounting groove 11 and is slidably supported in the arc-shaped sliding groove 47.

[0145] In actual installation, when the first magnetic member 222 and the second magnetic member 311 are attracted to each other, Figure 9 As shown, the limiting ball 46 is located at the left end of the arc-shaped sliding groove 47. At this time, the user can manually rotate the display screen 3 so that the arc-shaped male buckle 45 rotates in the arc-shaped female buckle 44. At the same time, the limiting ball 46 slides to the right along the arc-shaped sliding groove 47. Figure 8 As shown, when the arc-shaped male buckle 45 moves to the rotation lock with the arc-shaped female buckle 44, the limiting ball 46 slides into the circular limiting groove 48 and no longer moves. In this way, the user can be prompted that the rotation is in place through a process of changing the rotation force from loose to tight and then to loose, and the user can feel that the display screen 3 is locked.

[0146] It should be noted that the limiting ball 46 extends into the arc-shaped sliding groove 47, which to a certain extent avoids the phenomenon of insufficient attraction and unstable fixation caused by the limiting ball 46 supporting the display screen 3 outward.

[0147] In some embodiments, the arcuate female buckle 44 and the arcuate male buckle 45 are both multiple and matched one-to-one, and the multiple arcuate female buckles 44 are distributed at intervals along the circumference of the accommodating portion 22.

[0148] That is, the number of arc-shaped female buckles 44 and arc-shaped male buckles 45 can be set to two, three or even more, and multiple arc-shaped female buckles 44 and multiple arc-shaped male buckles 45 are matched one by one, and multiple arc-shaped female buckles 44 are evenly distributed along the circumference of the accommodating portion 22. In this way, the locking effect can be improved, so that the connection between the display screen 3 and the mounting bracket 2 is more firmly, and the display screen 3 is prevented from loosening or shaking. In addition, multiple arc-shaped female buckles 44 and arc-shaped male buckles 45 are evenly distributed, which can reduce the force on a single arc-shaped female buckle 44 and arc-shaped male buckle 45, thereby extending their service life.

[0149] In some embodiments, the mounting bracket 2 is provided with an electrical adapter 23, the electrical adapter 23 is provided with a contact pressing portion 231, the display screen 3 is provided with a contact portion 3111 and an avoidance groove 3112, the contact pressing portion 231 is suitable for extending into the avoidance groove 3112, and after the display screen 3 and the accommodating portion 22 are rotated and locked, the contact pressing portion 231 slides out of the avoidance groove 3112 and presses against the contact portion 3111.

[0150] Specifically, if Figure 4 and Figure 5 As shown, the mounting bracket 2 is provided with an electrical adapter 23, and a contact pressing portion 231 is provided on the side of the electrical adapter 23 facing the display screen 3. Figure 8 As shown, the display screen 3 is provided with an avoidance groove 3112 and a contact portion 3111 adapted to the contact pressing portion 231 , and the contact portion 3111 can be provided at the left end position of the avoidance groove 3112 .

[0151] During the actual installation process, when the first magnetic part 222 and the second magnetic part 311 are automatically aligned and attracted, the contact pressing part 231 extends into the avoidance groove 3112 to avoid the contact pressing part 231 to prevent damage to the contact pressing part 231 during rotation, thereby affecting the electrical connection effect. After the display screen 3 and the accommodating part 22 are rotationally locked, that is, the arc-shaped male buckle 45 has been screwed into the arc-shaped female buckle 44 for rotation locking, at this time, the contact pressing part 231 slides out of the avoidance groove 3112 and aligns and presses on the contact part 3111, thereby realizing the electrical connection between the electrical adapter 23 and the display screen 3.

[0152] It should be noted that the contact pressing portion 231 extends into the avoidance groove 3112, which to a certain extent avoids the insufficient attraction and unstable fixation caused by the contact pressing portion 231 pushing the display screen 3 outward.

[0153] In some embodiments, the thickness of the accommodating portion 22 protruding from the mounting base 1 is d, and satisfies: 5 cm ≤ d ≤ 7 cm.

[0154] That is, the thickness d of the accommodating portion 22 protruding from the mounting base 1 can be set to 5cm, 6cm, 6.5cm, 7cm, etc. By setting the thickness d of the accommodating portion 22 protruding from the mounting base 1 within the range of 5cm≤d≤7cm, the thickness of the accommodating portion 22 protruding from the seat 100 can be about 6cm, so that the accommodating portion 22 achieves an ultra-thin effect, which meets the requirements of the regulations on protruding objects of passenger cars, that is, it avoids the setting of the seat 100 being too thick and causing harm to the user. The user can install the mounting bracket 2 on the seat 100 for a long time without having to remove it after each use, thereby improving the convenience of use.

[0155] In some embodiments, an arc-shaped rounded corner is formed on an edge of one side of the accommodating portion 22 facing away from the mounting portion 21 .

[0156] Specifically, if Figure 4 As shown, the edge of the receiving portion 22 facing away from the mounting portion 21, i.e., the side facing the display screen 3, has a rounded corner. For example, the rounded corner can be set to at least R4. The design can be flexible based on actual needs and is not limited to the embodiment described herein. This rounded corner prevents the edge of the receiving portion 22 exposed to the seat 100 from being too sharp and potentially harmful to passengers, thereby further improving user safety and complying with regulations regarding protrusions on passenger vehicles.

[0157] The present invention also provides a screen assembly.

[0158] The screen assembly according to an embodiment of the present invention includes a display screen 3 and a screen mounting assembly 102 according to any one of the above embodiments. The display screen 3 is provided with a mating portion 31 , which extends into the mounting bracket 2 and is rotationally locked with the mounting bracket 2 .

[0159] Specifically, the display screen 3 can display images and video information, etc., to achieve interaction with the user. A mating portion 31 is provided on the display screen 3, and the mating portion 31 is facing the mounting bracket 2. The mating portion 31 and the mounting bracket 2 can be rotated and locked by the arc-shaped female buckle 44 and the arc-shaped male buckle 45 to achieve fixed installation of the display screen 3 on the mounting bracket 2, ensuring the stability and safety of the display screen 3 when in use, avoiding it from shaking, tilting, etc., affecting the user experience, and reducing the risk of escape or damage due to accidental collision or vibration.

[0160] The present invention also provides a seat 100 .

[0161] The seat 100 according to the embodiment of the present invention includes a seat body 101 and a screen mounting assembly 102 according to any one of the above embodiments or a screen assembly according to any one of the above embodiments, and the mounting base 1 is embedded in the surface of the seat body 101 .

[0162] Specifically, if Figures 16-21 As shown, the seat 100 includes a seat body 101 and the above-mentioned screen mounting assembly 102, and the mounting base 1 is embedded in the surface of the seat body 101. A mounting groove can be set on the seat body 101, and the mounting groove is adapted to the shape and size of the mounting base 1, and the depth of the mounting groove is consistent with the axial size of the mounting base 1, so that the mounting base 1 can be embedded in the surface of the seat body 101, so that the surface of the mounting base 1 is flush with the surface of the seat body 101, reducing the space occupied by the mounting base 1, and thereby realizing the installation and fixation of the screen mounting assembly 102 on the seat 100.

[0163] from Figure 20 As can be seen from the figure, the overall size of the screen mounting assembly 102 is compact, and the distance between it and the seat 100 is very small, which greatly reduces the space occupied in the back row.

[0164] In the screen mounting assembly 102, the mounting portion 21 of the mounting bracket 2 is detachably mounted in the mounting groove 11 of the mounting base 1, thereby realizing fixed installation of the mounting bracket 2 on the mounting base 1, and the mounting portion 21 is hidden in the mounting base 1, reducing the space occupied in the rear row; the accommodating portion 22 extends into the accommodating groove 221 and is rotated and locked with the accommodating portion 22, thereby realizing fixed installation of the display screen 3 on the mounting bracket 2, ensuring the stability and safety of the display screen 3 when in use, avoiding shaking, tilting, etc., which affects the user experience, and the accommodating portion 22 is an ultra-thin structure, and the protruding distance relative to the seat 100 is very small, which complies with the requirements of the vehicle regulations and will not cause harm to the passengers. The mounting bracket 2 can be installed on the seat 100 for a long time. After being installed in conjunction with the display screen 3, the thickness of the screen mounting assembly 102 is reduced, further reducing the space occupied in the rear row, and has a wide range of applications.

[0165] In some embodiments, the mounting base 1 is embedded in the rear side of the seat body 101 .

[0166] That is to say, the screen mounting assembly 102 is installed on the rear side of the seat body 101, and a mounting groove can be set on the rear side of the seat body 101 so that the mounting base 1 is embedded in the rear side of the seat body 101, so that the mounting base 1 is flush with the rear side surface of the seat body 101, and the appearance is neater and more unified, which not only increases the firmness of the mounting base 1, but also shortens the size of the screen mounting assembly 102, that is, reduces the space occupied by the screen mounting assembly 102 behind the seat 100.

[0167] The present invention also provides a vehicle.

[0168] According to an embodiment of the present invention, the vehicle includes the screen mounting component 102 of any one of the above-mentioned embodiments or the screen assembly of the above-mentioned embodiments, or the seat 100 of any one of the above-mentioned embodiments. By setting the above-mentioned screen mounting component 102 or screen assembly, the space occupied by the screen mounting component 102 or the screen assembly on the vehicle can be reduced. By setting the above-mentioned seat 100, the space occupied by the seat 100 can be reduced, thereby improving the space utilization and safety of the vehicle. The rechargeable mounting base 1 increases the use function of the vehicle and improves the passenger's use experience.
