[0002] With the continuous development of automobile technology, in-car screens have become an important part of modern cars. Early in-car screens could only display basic vehicle information, such as speed, fuel level, water temperature, etc., and most of them were digital screens. With the advancement of electronic technology, LCD screens have been widely used in vehicles, allowing more information and images to be displayed on in-car screens. With the popularity of smartphones and tablets, the functions of in-car screens are becoming more and more abundant. Today's in-car screens can not only display basic information and entertainment content such as navigation, music, and videos, but can also connect to the Internet to provide more personalized services such as online music, social media, and smart home control.

[0003] Traditional in-car screens are mostly fixed, and users need to lower or raise their heads to adjust to the screen when watching. This causes problems such as eye fatigue and stiff neck after long-term viewing, which greatly affects the user experience. In order to provide user comfort, some car models have developed an angle-adjustable in-car screen. However, the structure of these in-car screens is complex, resulting in a significant increase in processing and installation costs.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0044] In order to solve or improve to a certain extent the technical problem of the complex structure of the vehicle-mounted screen in the prior art, the utility model provides a screen assembly 1. The screen assembly 1 includes: a mounting bracket 10; a transmission mechanism 30, the transmission mechanism 30 includes a first transmission member 31 and a second transmission member 32 connected to each other, the first transmission member 31 is slidably fixed on the mounting bracket 10, and the second transmission member 32 is rotatably fixed on the mounting bracket 10; a screen body 40, the screen body 40 is fixedly connected to the second transmission member 42; and a driving mechanism 20, the driving mechanism 20 is connected to the first transmission member 31 to drive the first transmission member 31 to slide on the mounting bracket 10, thereby synchronously driving the screen body 40 to rotate relative to the mounting bracket 10 along with the second transmission member 32.

[0045] like Figure 1 As shown, in one or more embodiments, the screen assembly 1 of the utility model includes a mounting bracket 10, a driving mechanism 20, a transmission mechanism 30 and a screen body 40 (see Figure 5 and Figure 6 ) and other components. The mounting bracket 10 can be made of a suitable metal material (such as cast iron, aluminum alloy) through a casting process to form an integral body, so that it has good mechanical strength. The transmission mechanism 30 is connected to the driving mechanism 20 and the screen body 40 respectively. When the driving mechanism 20 is working, the transmission mechanism 30 can drive the screen body 40 to rotate relative to the mounting bracket 10, thereby adjusting the angle of the screen body 40. The screen assembly 1 has a compact structure and good stability and reliability.

[0046] like Figure 2 As shown, in one or more embodiments, the mounting bracket 10 includes a bracket body 11 and side walls 12 arranged at both ends of the bracket body 11 opposite to each other, so that the entire mounting bracket 10 has a substantially U-shaped shape. The bracket body 11 can be used to fix the drive mechanism 20. In one or more embodiments, two drive motor mounting holes 111 spaced from each other are provided on the bracket body 11, and each drive motor mounting hole 111 can be matched with a suitable fastener (such as a bolt, a screw, etc.) to fix the drive motor 21 in the drive mechanism 20 on the bracket body 11. It should be noted that the number and arrangement position of the drive motor mounting holes 111 can be adjusted according to actual needs, as long as the drive motor 21 can be fixed on the bracket body 11. In one or more embodiments, a screw through hole 112 spaced from the drive motor mounting hole 111 is also provided on the bracket body 11. The screw through hole 112 allows the screw 22 in the drive mechanism 20 to pass through it so as to match the first transmission member 31 in the transmission mechanism 30.

[0047] based on Figure 1 and Figure 2In the orientation shown, the side walls 12 extend rearward approximately vertically from the left and right sides of the bracket body 11. A slide groove 121 extending approximately in the front-to-back direction is provided on each side wall 12. The slide grooves 121 on the left and right side walls 12 are opposite to each other, so that the first transmission member 31 can slide conveniently in the slide groove 121. In one or more embodiments, a plastic package (not shown in the figure) surrounding the slide groove 121 is also provided on each side wall 12 to reduce the friction force when the first transmission member 31 slides in the slide groove 121, thereby reducing vibration and noise.

[0048] Continue to see Figure 2 , each side wall 12 is further provided with an axis hole 122 spaced apart from the slide groove 121. The axis holes 122 located on the left and right side walls 12 are opposite to each other, so that the second transmission member 32 can be easily rotated in the axis hole 122.

[0049] Continue to see Figure 2 In one or more embodiments, each side wall 12 is further provided with a harness through hole 123. The harness through holes 123 on the left and right side walls 12 are opposite to each other. The arrangement of the harness through holes 123 allows the harnesses such as power lines and communication lines connected to the screen body 40 to pass through them conveniently for easy wiring. It should be noted that the number and arrangement positions of the harness through holes 123 can also be adjusted according to actual needs.

[0050] Continue to see Figure 2 In one or more embodiments, the mounting bracket 10 further includes lugs 13. Specifically, the lugs 13 are respectively arranged on the side walls 12 on the left and right sides. Each lug 13 is configured to extend vertically from the vertical edge of the side wall 12 close to the bracket body 11 toward a direction away from the bracket body 11. Taking the lug 13 located on the left side wall 12 as an example, the lug 13 extends approximately vertically from the vertical edge (i.e., the front edge) of the left side wall 12 close to the bracket body 11 toward a direction away from the bracket body 11 (i.e., to the left). The provision of the lugs 13 can enhance the rigidity and structural strength of the entire mounting bracket 10. In one or more embodiments, a fixing hole 15 is provided on each lug 13, and two fixing holes 15 spaced apart from each other are also provided on the bracket body 11. Each fixing hole 15 can be matched with a suitable fastener (e.g., a bolt, a screw, etc.) to fix the mounting bracket 10 in a predetermined installation area. Alternatively, the fixing hole 15 may be provided only on the bracket body 11 , or only on the lug 13 , as long as the mounting bracket 10 can be firmly fixed on the predetermined mounting area.

[0051] Continue to see Figure 2In one or more embodiments, the mounting bracket 10 further includes a positioning claw 14. Specifically, the positioning claw 14 is respectively arranged on the lugs 13 on the left and right sides. Each positioning claw 14 is configured to extend vertically from a vertical edge away from the side wall 12 toward a direction away from the side wall 12. Taking the positioning claw 14 located on the right lug 13 as an example, the positioning claw 14 extends approximately vertically from the vertical edge of the right lug 13 away from the right side wall 12 (i.e., the right edge) toward a direction away from the right side wall 12 (i.e., forward). Each positioning claw 14 can be matched with a positioning hole arranged on a predetermined installation area, thereby improving the efficiency and accuracy of positioning and installing the mounting bracket 10.

[0052] like Figure 3 As shown, in one or more embodiments, the driving mechanism 20 includes components such as a driving motor 21, a screw rod 22 and a sleeve 23. In one or more embodiments, the driving motor 21 is fixed to the bracket body 11 of the mounting bracket 10, so that the entire screen assembly 1 has a stable structure. Alternatively, the driving motor 21 can also be fixed to other suitable positions, such as fixed to the back frame of the vehicle seat (not shown in the figure). The screw rod 22 is connected to the output shaft (not shown in the figure) of the driving motor 21, and the sleeve 23 matched with the screw rod 22 is fixed to the first transmission member 31. Through the above-mentioned arrangement, when the output shaft of the driving motor 21 is controlled to rotate forward or reverse, the screw rod 22 will rotate forward or reverse with the output shaft, and the first transmission member 31 connected to the sleeve 23 will be driven to move in the direction close to the driving motor 21 (i.e. forward) or away from the driving motor 21 (i.e. backward).

[0053] Continue to see Figure 3 , the drive motor 21 may be, but not limited to, a stepper motor, a servo motor, etc. In one or more embodiments, a first buffer pad 26 is provided between the drive motor 21 and the bracket body 11 to reduce the vibration and noise generated when the drive motor 21 is working. The material of the first buffer pad 26 may be, but not limited to, rubber, etc. In one or more embodiments, a first metal pad 27 is further provided between the first buffer pad 26 and the drive motor 21 to improve the connection strength between the drive motor 21 and the mounting bracket 10. In one or more embodiments, a second buffer pad 28 is further provided on the side of the bracket body 11 away from the drive motor 21 (i.e., the rear side) to further reduce the vibration and noise generated when the drive motor 21 is working. The material of the second buffer pad 28 may be, but not limited to, rubber, etc. In one or more embodiments, a second metal pad 29 is further provided on the side of the second buffer pad 28 away from the bracket body 11 (i.e., the rear side) to further improve the connection strength between the drive motor 21 and the mounting bracket 10.

[0054] Continue to see Figure 3The screw rod 22 extends substantially in the front-rear direction. An external thread is provided on the outer peripheral surface of the screw rod 22. Figure 4 The sleeve 23 has a substantially circular shape. The sleeve 23 is fixed in the sleeve 23 mounting hole 3211 of the first transmission member 31. An internal thread matching the external thread of the screw rod 22 is provided on the inner circumferential surface of the sleeve 23, so that when the screw rod 22 rotates, the sleeve 23 can drive the first transmission member 31 to move forward or backward along the extension direction of the screw rod 22.

[0055] Continue to see Figure 3 In one or more embodiments, a first limit member 24 is sleeved on the screw rod 22. In the assembled state, the first limit member 24 is located between the bracket body 11 and the first transmission member 31. More specifically, the first limit member 24 is located between the second metal pad 29 and the first transmission member 31. When the first transmission member 31 moves in a direction toward the drive motor 21, due to the obstruction of the first limit member 24, a preset minimum distance can be spaced between the first transmission member 31 and the drive motor 21. In one or more embodiments, a second limit member 25 is also sleeved on the screw rod 22. The second limit member 25 is located at the end of the screw rod 22. Specifically, the second limit member 25 is located on the side of the first transmission member 31 away from the first limit member 24 (i.e., the rear side). When the first transmission member 31 moves in a direction away from the driving motor 21, due to the obstruction of the second limit member 25, a preset maximum distance can be spaced between the first transmission member 31 and the driving motor 21, and then the movement stroke of the first transmission member 31 is preset to ensure the reliability of the movement of the entire screen assembly 1.

[0056] like Figure 4 As shown, in one or more embodiments, the transmission mechanism 30 includes a first transmission member 31 and a second transmission member 32 connected to each other. The first transmission member 31 is slidably fixed on the mounting bracket 10, and the second transmission member 32 is rotatably fixed on the mounting bracket 10. The first transmission member 31 is connected to the driving mechanism 20 so as to slide relative to the mounting bracket 10 under the drive of the driving mechanism 20. When the first transmission member 31 slides, the first transmission member 31 synchronously drives the second transmission member 32 to rotate, thereby driving the screen body 40 fixedly connected to the second transmission member 32 to rotate relative to the mounting bracket 10.

[0057] Continue to see Figure 4In one or more embodiments, the first transmission member 31 has a rod-shaped structure 311 extending roughly along the length direction (i.e., the left-right direction) of the bracket body 11. A roughly circular sleeve 23 mounting hole 3211 is provided in the middle of the rod-shaped structure 311 to fix the sleeve 23. In one or more embodiments, a first fixing member 314 is provided at each of the left and right ends of the rod-shaped structure 311. The first fixing member 314 can be, but is not limited to, a bolt. The first fixing member 314 is slidably fixed in the slide groove 121 of the corresponding side wall 12. Specifically, a bushing 313 is sleeved on each first fixing member 314, and a slider (not shown in the figure) that can slide in the corresponding slide groove 121 is formed between the bushing 313 and the first fixing member 314, so that the first transmission member 31 can be slidably fixed on the mounting bracket 10.

[0058] Continue to see Figure 4 In one or more embodiments, the second transmission member 32 includes a rod-shaped body 321 and connecting rods 322 located on opposite sides of the rod-shaped body 321. The rod-shaped body 321 extends substantially along the length direction (i.e., the left-right direction) of the bracket body 11. In other words, the rod-shaped body 321 is substantially parallel to the first transmission member 31. The connecting rods 322 extend substantially vertically downward from the left and right sides of the rod-shaped body 321, so that the entire second transmission member 32 has a substantially U-shaped shape for easy processing.

[0059] Continue to see Figure 4 In one or more embodiments, two mounting holes 3211 spaced apart from each other are provided on the rod-shaped body 321. Each mounting hole 3211 can be matched with a suitable fastener (such as a bolt, a screw, etc.) to fix the screen body 40 on the second transmission member 32. The mounting hole 3211 can be, but is not limited to, a circular hole, a waist-shaped hole, etc. The number of mounting holes 3211 can also be set to other suitable numbers more or less than 2. In one or more embodiments, an avoidance groove 3212 extending forward from the rear edge is also provided on the rod-shaped body 321 to avoid the back protrusion of the screen body 40 (not shown in the figure), so that the screen body 40 can be fixed on the second transmission member 32 more compactly. Alternatively, the screen body 40 and the second transmission member 32 can also be connected by other suitable fixing methods, such as a snap-on connection, etc.

[0060] Continue to see Figure 4 In one or more embodiments, the rod-shaped body 321 is rotatably fixed to the mounting bracket 10 through the second fixing member 323. Specifically, a conical protrusion (not shown in the figure) is respectively provided at the left and right ends of the rod-shaped body 321. The second fixing member 323 extends through the corresponding shaft hole 122 on the side wall 12 and is fixed on the conical protrusion, so that the second transmission member 32 is rotatably fixed to the mounting bracket 10.

[0061] Continue to see Figure 4 In one or more embodiments, an elastic member 324 is further sleeved on the rod-shaped body 321. The elastic members 324 are respectively arranged at the left and right ends of the rod-shaped body 321. One end of each elastic member 324 is fixed to the corresponding connecting rod 322, and the other end is fixed to the corresponding side wall 12. Taking the elastic member 324 located on the left side as an example, the elastic member 324 is sleeved on the left end of the rod-shaped body 321. Specifically, the elastic member 324 is sleeved on the conical protrusion located on the left side of the rod-shaped body 321. One end of the elastic member 324 is fixed to the connecting rod 322 on the left side, and the other end is fixed to the left side wall 12. When the second transmission member 32 rotates relative to the mounting bracket 10, the setting of the elastic member 324 can provide suitable damping for the second transmission member 32 to ensure that the screen body 40 rotates smoothly.

[0062] like Figure 4 As shown, in one or more embodiments, the transmission mechanism 30 further includes a third transmission member 33 for connecting the first transmission member 31 and the second transmission member 32. The two ends of the third transmission member 33 are pivotally connected with the first transmission member 31 and the second transmission member 32 respectively. Specifically, the third transmission member 33 has a first end 331 and a second end 332 opposite to each other. In the assembled state, the two opposite ends of the rod-shaped structure 311 of the first transmission member 31 are respectively connected to the first end 331 of the third transmission member 33 through a first fixing member 314. In addition, the connecting rod 322 of the second transmission member 32 is connected to the second end 332 of the third transmission member 33 close thereto through a third fixing member 333. Taking the third transmission member 33 located on the left side as an example, the third transmission member 33 has a first end 331 located on the front side and a second end 332 located on the rear side. The first end 331 of the third transmission member 33 is connected to the left end of the first transmission member 31 through the first fixing member 314. The second end 332 of the third transmission member 33 is connected to the connecting rod 322 on the left side of the second transmission member 32 through the third fixing member 333. The third transmission member 33 may be, but is not limited to, a bolt. Through the above arrangement, when the first transmission member 31 slides relative to the mounting bracket 10, the connecting rod action of the third transmission member 33 can drive the second transmission member 32 to rotate relative to the mounting bracket 10, thereby achieving the adjustment of the angle of the screen body 40.

[0063] As Figure 5 and Figure 6 As shown, the screen body 40 of the screen assembly 1 of the present invention is fixedly connected to the second transmission member 32. The screen body 40 can be a display screen, a touch screen or other suitable screens.

[0064] Continue to see Figure 5 and Figure 6, the screen body 40 has a relative first working position and a second working position. When the screen body 40 is in the first working position, the screen body 40 flips upward to form a maximum limit angle with the horizontal plane. When the screen body 40 is in the second working position, the screen body 40 flips downward to form a minimum limit angle with the horizontal plane. It can be understood that the user can rotate the screen body 40 to any position between the first working position and the second working position (the overall rotation angle exceeds 90°) to better meet the comfort requirements.

[0065] Continue to see Figure 5 When the screen body 40 is in the first working position, the first transmission member 31 is located at the rear end of the slide slot 121; the second stopper 25 abuts against the first transmission member 31 to restrict the movement of the first transmission member 31. In other words, the screen body 40 cannot continue to rotate counterclockwise (based on Figure 5 When the angle of the screen body 40 needs to be adjusted, the driving mechanism 20 can control the first transmission member 31 to slide forward along the slide slot 121, and the second transmission member 32 will rotate clockwise under the drive of the third transmission member 33, thereby driving the screen body 40 to rotate clockwise.

[0066] Continue to see Figure 6 When the screen body 40 is in the second working position, the first transmission member 31 is located at the front end of the slide slot 121; the first stopper 24 abuts against the first transmission member 31 to restrict the movement of the first transmission member 31. In other words, the screen body 40 cannot continue to move clockwise (based on Figure 6 When the angle of the screen body 40 needs to be adjusted, the driving mechanism 20 can control the first transmission member 31 to slide backward along the slide slot 121, and the second transmission member 32 will rotate counterclockwise under the drive of the third transmission member 33, thereby driving the screen body 40 to rotate counterclockwise.

[0067] The utility model also provides a seat (not shown in the figure). The seat includes the screen assembly 1 and the seat frame described in any of the above embodiments, and the mounting bracket 10 of the screen assembly 1 is fixed to the rear of the seat frame. Specifically, the seat frame includes a backrest frame and a headrest frame, and the mounting bracket 10 can be fixed to the rear of the backrest frame or the rear of the headrest frame. Through the above arrangement, passengers sitting at the rear of the seat can easily view the screen body 40 of the screen assembly 1, thereby improving the riding experience. Since the angle of the screen body 40 can be easily adjusted, different users (such as adults, children, etc.) can adjust the rotation angle of the screen body 40 according to their own needs to ensure the comfort of the user. In addition, when the seat position changes, such as moving forward and backward or flipping, the mounting bracket 10 of the screen assembly 1 will move with the seat frame, and the screen body 40 can adjust the angle to better meet the needs of the user.

[0068] The utility model also provides a vehicle (not shown in the figure). The vehicle comprises the screen assembly 1 described in any of the above embodiments or the seat described in any of the above embodiments.
