DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-6 The present invention is described in further detail.

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0030] This application is used to install the corresponding product 700 (such as Figure 1 and Figure 2 As shown), such as a vehicle-mounted display screen, a vehicle-mounted electric ceiling screen, an electric folding table top, etc. The following takes the vehicle-mounted display screen as an example for explanation.

[0031] With the development of the automobile industry, in order to improve the riding experience of passengers in vehicles, on-board display screens are installed on the main and co-pilot seats, and even on the back seats. In order to improve the convenience of using the on-board display screens on the co-pilot seats or back seats, the on-board display screens are installed through a driving mechanism so that the on-board display screens have functions such as storage and angle adjustment. Figure 1-Figure 6 The specific structure of the driving mechanism described in this application is described in detail.

[0032] Reference Figure 1 and Figure 2 The driving mechanism includes a mounting portion 100, which is used to mount the vehicle display screen. The specific shape of the mounting portion 100 is adaptively adjusted according to actual usage requirements. In this embodiment, the shape of the mounting portion 100 is most preferably a plate, one side (front) is used to mount the product, and the other side (back) is used to connect with the corresponding driving component.

[0033] like Figure 3-Figure 5As shown, in order to drive the mounting part 100 to make linear motion so as to achieve the purpose of storing the vehicle-mounted display screen and adjusting the position of the vehicle-mounted display screen, the present application also includes a first driving unit 200 for driving the mounting part 100 to make linear reciprocating motion, which mainly includes a first slider 210 and a first driving assembly. The first slider 210 is connected to the mounting part 100, and the first driving assembly includes a first lead screw 220 and a first power member 230. The axial direction of the first lead screw 220 is consistent with the sliding direction of the first slider 210. The first lead screw 220 is threadedly connected to the first slider 210 (specifically, a connecting block can be provided on one side of the first slider 210, and the first lead screw 220 is passed through the connecting block and threadedly connected to the connecting block). The first power member 230 is used to drive the first lead screw 220 to rotate. The first power member 230 can adopt a motor, etc., so that, The first screw 220 is driven to rotate by the first power member 230. Since the first screw 220 is threadedly connected to the first slider 210, when the first screw 220 rotates, the first slider 210 moves axially along the first screw 220. In order to prevent the first slider 210 from rotating on the first screw 220, two first guide rods 240 are provided. The axial direction of the first guide rods 240 is consistent with the axial direction of the first screw 220. The first slider 210 is clamped on both sides of the two first guide rods 240. In this way, the movement of the first slider 210 is guided and restricted, ensuring that the first slider 210 only makes translational movement, thereby achieving the purpose of accommodating the vehicle-mounted display screen and adjusting the position of the vehicle-mounted display screen. During installation, the two first guide rods 240 and the first screw 220 can be fixed on a mounting frame inside the vehicle, such as a fixing frame in a glove box.

[0034] like Figure 3-Figure 6As shown, in order to facilitate adjustment of the angle of the mounting portion 100 so as to satisfy the passengers' viewing of the vehicle-mounted display screen from different angles, the present application also includes a second driving unit 300, which mainly includes a second slider 310, a connecting rod 320 and a second driving assembly, wherein the sliding direction of the second slider 310 is consistent with the sliding direction of the first slider 210, and the two ends of the connecting rod 320 are rotatably connected to the second slider 310 and the mounting portion 100 respectively, and the second driving assembly mainly includes a second lead screw 330 and a second power member 340, the axial direction of the second lead screw 330 is consistent with the movement direction of the second slider 310, the second slider 310 is threadedly connected to the second lead screw 330, and the second power member 340 is used to drive the second lead screw 330 to rotate. The second power member 340 can be a motor, etc., so that the second power member drives the second lead screw 330 to rotate. Since the first lead screw 330 and The second slider 310 is threadedly connected, so when the second screw 330 rotates, the second slider 310 moves along the axial direction of the second screw 330, and in order to prevent the second slider 310 from rotating on the second screw 330, two second guide rods 350 are provided, and the axial direction of the second guide rod 350 is consistent with the axial direction of the second screw 330, and the second slider 310 is clamped on both sides of the two second guide rods 350, so as to guide and limit the movement of the second slider 310, and ensure that the second slider 310 only makes translational movement, so that the second slider 310 and the first slider 210 make the same direction or different directions on two parallel planes. When the second slider 310 moves, the connecting rod 320 moves, so that the connecting rod 320 moves away from one end of the second slider 310, and then the mounting part 100 rotates around the connection with the first slider 210, so as to achieve the purpose of adjusting the angle of the vehicle-mounted display screen.

[0035] Further optimization is that the connecting rod 320 is bent, that is, the two ends of the connecting rod 320 point to different directions, so that the angle of the vehicle-mounted display screen installed on the mounting portion 100 can be adjusted to a larger range within a limited range of motion, so that the vehicle-mounted display screen can be adjusted to a position parallel to the first slider 210 (such as Figure 1 If the driving mechanism is placed in the glove box (or space is left at the bottom of the driving mechanism), the vehicle display screen can be stored in the glove box, thereby achieving better storage of the vehicle display screen.

[0036] like Figure 3-Figure 6As shown, in the present application, the second driving unit is arranged on the first driving unit, specifically: a support seat 400 is arranged on the first slider 210, and the second lead screw 330 is arranged on the support seat 400. In this way, when the first slider 210 moves, the second slider 310, the connecting rod 320, the second lead screw 330 and the second power member 340 move synchronously with the first slider 210. The purpose of such a setting is that when the first slider 210 moves to adjust the position of the vehicle-mounted display screen, the angle of the vehicle-mounted display screen will not change. When the angle of the vehicle-mounted display screen needs to be adjusted, it is only necessary to move the second slider 310 relative to the first slider 210. Of course, the movement of the first slider 210 and the movement of the second slider 320 relative to the first slider 210 can be carried out synchronously, so as to achieve the purpose of synchronously adjusting the position (extension amount) and angle of the vehicle-mounted display screen.

[0037] Further optimization is that Figure 3 and Figure 4 As shown, in order to reduce the size of the driving mechanism, a through hole 600 is opened on the first slider 210, and the connecting rod 320 passes through the through hole 600, so that the installation space and activity space of the connecting rod 320 coincide with the installation space and activity space of the first slider 210, thereby reducing the volume of the mechanism, thereby reducing the space required for installing the driving mechanism, and an inclined surface is provided at one end of the through hole 600 away from the mounting portion 100. When the connecting rod 320 moves to the side of the through hole 600 away from the mounting portion 100, the connecting rod 320 can fit on the inclined surface.

[0038] Further optimization is that Figure 4 As shown, in order to facilitate the installation of the mounting part 100, two groups of parallel connecting members 110 are provided on one side of the mounting part 100, and the first slider 210 and the connecting rod 320 are rotatably connected to the mounting part 100 through the two connecting members 110 respectively, so as to achieve the purpose of flexibly adjusting the position and angle of the mounting part 100.

[0039] Further optimization is that Figure 1 and Figure 2 As shown, in order to facilitate the installation of the drive mechanism, the drive mechanism also includes an integrated seat 500, and the first drive unit 200 and the second drive unit 300 are both arranged on the integrated seat 500. In this way, the first guide rod 240 and the second guide rod 350 can be arranged on the integrated seat 500, and the first slider 210 and the second slider 310 are both arranged on the inner side of the integrated seat 500. When installing the drive mechanism, it is only necessary to fix the integrated seat 500 on the vehicle's mounting frame (such as the frame at the glove box) to complete the installation of the drive mechanism, thereby improving the installation efficiency and also playing the function of protecting the first drive unit and the second drive unit.

[0040] The invention also discloses a vehicle-mounted display screen, comprising the driving mechanism.

[0041] The invention also discloses a vehicle comprising the driving mechanism.

[0042] In summary, by providing the first driving unit 200 and the second driving unit 300, the mounting portion 100 is driven to perform linear motion and flip, respectively, so that the position and angle of the vehicle-mounted display screen installed at the mounting portion 100 can be adjusted to meet the different use requirements of passengers and improve the use experience of passengers;

[0043] Due to the diversity of the internal structure of the car, the installation space of the driving mechanism of the vehicle display screen is limited. Therefore, the installation space required for the driving mechanism is as small as possible. The driving mechanism described in the present application can adjust the position and angle of the vehicle display screen through two first sliders 210 and second sliders 310 that perform linear motion. The structure is simple and compact, and can be placed in the glove box of the co-pilot of the car and other narrow spaces.

[0044] By using the driving mechanism to install the vehicle display screen, the vehicle display screen installed on the mounting portion 100 can be adjusted to a wider angle, so that the vehicle display screen can be adjusted to a position parallel to the first slider 210, so as to better store the vehicle display screen.

[0045] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
