Description

Technical Field

[0001] The utility model relates to the field of automobile intelligent cockpits, in particular to a vehicle-mounted screen motion mechanism. Background Art

[0002] With the development of automobile technology, smart cockpits are becoming more and more popular in cars. In order to provide customers with a better experience, various automobile manufacturers are increasingly equipping cars with large-size screens for passenger entertainment. In order to facilitate passengers' viewing, the screens installed on the roof are mostly opened and folded by rotating. The existing technology generally uses motors to drive gear shafts, worm gears and other connecting rod components to drive the screen to flip. There are many transmission levels, large space occupation, and high costs. It does not meet the ultimate space design of the smart cockpit of the car and the trend of enterprises to reduce costs and improve efficiency. Utility Model Content

[0003] In view of the above-mentioned problems, the purpose of the present utility model is to provide a vehicle-mounted screen movement mechanism with compact structure, small space occupation, flexible layout, stable operation and the ability to reduce costs.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A vehicle-mounted screen movement mechanism is provided, comprising a driving component and at least one driven component, wherein the driven component comprises a fixed frame, a slider slidably connected to the fixed frame, a connecting rod unit rotatably connected to the slider, and a reversing disk arranged at both ends of the moving path of the slider, the driving component comprises a driver and a cable, the cable passes through the reversing disk and is connected to the slider, and the driver pulls the slider to slide through the cable to drive the connecting rod unit to move synchronously.

[0006] In this solution, the driver is fixed on the vehicle body, and the driver and the driven component are controlled and connected by cables. Because the cables are flexible and can be bent at any angle, they are not restricted by space and can effectively utilize narrow space to achieve the purpose of saving space. At the same time, cables have cost advantages compared with transmission components such as gear shafts and screws. The fixing frame is installed and fixed on the side of the driver, and the connecting rod unit is locked and connected to the screen. The cable is connected to the slider after the direction is changed by the reversing disk. The cable is driven by the driver to pull the slider to slide, so as to drive the connecting rod unit to move, and finally realize the sliding and flipping of the screen. The cable-driven connection method requires less assembly accuracy between components, and can still operate stably without abnormal noise when the vehicle body is slightly deformed. In the assembly of the interior of the whole vehicle, the split components can be installed and fixed separately, without the need for pre-processing and assembly into the screen assembly for installation, which saves assembly processes and reduces production costs, which is in line with the trend of enterprises to reduce costs and improve efficiency.

[0007] Furthermore, the driving assembly also includes a gear box, the driving end of the driver is connected to the gear box, and the cable is passed through and connected to the gear box.

[0008] The gearbox is connected to the driver and fixed beside it. After the transmission and conversion of the gearbox, the driving force is transmitted to the cable to realize the telescopic linear motion of the cable. After the direction of the cable is changed by the reversing disk, it is connected to the slider, thereby pulling the driven component to move.

[0009] Furthermore, a limit block is provided at the end of the cable, and a limit groove is provided on the sliding block, and the limit block is snap-fitted and embedded in the limit groove.

[0010] The cable and the slider adopt a snap-in connection method that is easy to install and disassemble. A limit block is set at the end of the cable, and a limit groove is set on the slider. The limit block can be stably embedded in the limit groove, and during the movement of the slider, the limit block always maintains a mutual force between the limit block and the slider, and the limit block cannot be separated from the limit groove.

[0011] Furthermore, a limiting hole is provided on a side wall where the limiting groove abuts against the limiting block, and the pull cable is inserted through the limiting hole.

[0012] In order to further ensure the stability of the connection between the limiting block and the limiting groove, a limiting hole is opened on the side wall of the limiting groove, and the cable is engaged in the limiting hole to ensure that the cable cannot escape from the limiting hole.

[0013] Furthermore, the fixed frame is provided with a reversing bracket, and the reversing disc is arranged on the reversing bracket and is rotatably connected to the reversing bracket.

[0014] The reversing bracket has a protruding rotating shaft, and the center of the reversing disc has a rotating hole. The rotating hole of the reversing disc is inserted into the rotating shaft so that the reversing disc can rotate around the rotating shaft. When the cable acts on the reversing disc, the sliding friction between the two is converted into rolling friction, which avoids the wear of the cable and the reversing disc and increases the service life.

[0015] Furthermore, a groove is provided on the outer periphery of the reversing disc, and the cable is embedded in and passes through the groove.

[0016] The outer circumference of the commutation disc is provided with a groove, and the cable is embedded in the groove, so as to prevent the cable from detaching from the commutation disc due to the accumulation of long-term movement deviation, resulting in drive failure, and improve the stability of the mechanism.

[0017] Furthermore, the connecting rod unit includes a screen bracket and a rotating arm, one end of the rotating arm is hinged to the fixing frame, and the other end of the rotating arm is hinged to the screen bracket.

[0018] The rotational connection between the screen and the fixed frame is achieved by a connecting rod unit. A rotating base is set on the fixed frame. One end of the rotating arm is hinged to the rotating base, and the other end is hinged to the screen bracket. When the screen bracket moves, the connection point between the rotating arm, the rotating base and the screen bracket rotates, causing the angle of the connecting rod unit to change, thereby realizing the rotation of the screen.

[0019] Furthermore, a connecting arm is provided on a side of the screen bracket close to the slider, and the connecting arm is rotatably connected to the slider.

[0020] A connecting arm is provided on the outward side of the screen bracket, and a connecting part is provided on the side of the slider for rotating with the connecting arm. The slider slides under the pull of the cable, synchronously driving the screen bracket to slide. At the same time, the screen bracket rotates around the rotating axis of the connecting arm, so that the angle of the screen bracket changes, thereby realizing the rotation of the screen.

[0021] Furthermore, the screen bracket is also provided with a positioning column and a connecting hole, the positioning column is inserted into the positioning hole of the vehicle-mounted screen, and the screen bracket is penetrated through the connecting hole by a threaded connector and is locked and connected to the vehicle-mounted screen.

[0022] In order to facilitate the installation and fixation of the screen, the screen and the screen bracket are connected by threads. First, the positioning and fixation between the screen bracket and the screen are achieved through the positioning assembly, and then the screen bracket and the screen are fixed with screws. This method is not only simple to operate, but also stable and reliable.

[0023] Furthermore, there are two driven assemblies, the two driven assemblies are symmetrically arranged, and the driving assembly is arranged between the two driven assemblies.

[0024] Two driven components are provided, located on both sides of the vehicle-mounted screen. The driving component can drive the two driven components to move synchronously at the same time. The two driven components synchronously drive the vehicle-mounted screen to rotate from both sides of the vehicle-mounted screen, and the rotation process is smoother.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] In this solution, the driver is fixed on the vehicle body, and the driver and the driven component are controlled and connected by cables. Because the cables are flexible and can be bent at any angle, they are not restricted by space and can effectively utilize narrow space to achieve the purpose of saving space. At the same time, cables have cost advantages compared with transmission components such as gear shafts and screws. The fixing frame is installed and fixed on the side of the driver, and the connecting rod unit is locked and connected to the screen. The cable is connected to the slider after the direction is changed by the reversing disk. The cable is driven by the driver to pull the slider to slide, so as to drive the connecting rod unit to move, and finally realize the sliding and flipping of the screen. The cable-driven connection method requires less assembly accuracy between components, and can still operate stably without abnormal noise when the vehicle body is slightly deformed. In the assembly of the interior of the whole vehicle, the split components can be installed and fixed separately, without the need for pre-processing and assembly into the screen assembly for installation, which saves assembly processes and reduces production costs, which is in line with the trend of enterprises to reduce costs and improve efficiency.
