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

[0002] With the development of the automobile industry, in order to intuitively display some of the car's data and the user's multimedia needs, a car screen is equipped, which can be flipped open or closed when needed. In the current existing technology, the car screen is generally driven by a motor to make the connecting rod with the screen installed rotate synchronously in a certain direction to achieve screen flipping. Its transmission components are generally a combination of worms, gear shafts, lead screws, guide rails, etc. The large number of transmission levels leads to a complex structure, large space occupation, increased production and processing costs, and is not conducive to subsequent maintenance. Utility Model Content

[0003] The purpose of the utility model is to provide a vehicle-mounted screen flipping motion mechanism, aiming to solve the technical problems existing in the prior art such as complex structure, large space occupation, increased production and processing costs, and inconvenience in subsequent maintenance.

[0004] In order to solve the above technical problems, the utility model provides a vehicle-mounted screen flipping motion mechanism, including: a mounting bracket; two slide rail assemblies, which are arranged at intervals on the mounting bracket, and the slide rail assembly includes a guide rail and a slider slidably arranged on the guide rail; a connecting rod assembly, which is arranged on the mounting bracket, and the connecting rod assembly is connected to the slider, and the slider drives the connecting rod assembly to move when moving to drive the rotation of the screen; a transmission assembly, which is arranged on the mounting bracket, and includes a rotating drive member, a reel, a cable and a plurality of reversing disks, the rotating drive member is used to drive the rotation of the reel, the cable is wound on the reel and is sequentially wound around the plurality of reversing disks, and the two sliders are fixedly connected to the cable, and the reel will drive the cable to pull the two sliders to move synchronously in the same direction when rotating.

[0005] The two slide rail assemblies can stably drive the connecting rod assembly to rotate the screen, which is conducive to maintaining the stability of the screen flipping; the connecting rod assembly is connected to the screen to provide support for the screen, which is conducive to realizing the flipping of the screen;

[0006] The transmission assembly uses a cable to bypass multiple reversing disks and connect to two sliders, while driving the sliders of the two slide rail assemblies to move synchronously in the same direction along the guide rail. On the one hand, the cable is small in size and light in weight, and can be flexibly arranged in a smaller space, which is beneficial to improving space utilization and flexibility of structural design. During the transmission process, the dynamic friction between the cable and the contactable parts is small, which can reduce transmission noise. On the other hand, the transmission structure is simplified, which is beneficial to reducing production and processing costs, facilitating subsequent maintenance, and achieving stable flipping of the screen.

[0007] The use of a reversing disc is conducive to connecting the cable with the two sliders and pulling the sliders to move along the guide rails, thereby improving the stability of the transmission; the use of a winding disc allows the rotating drive member to stably drive the winding and unwinding of the cable, which is conducive to improving the stability of the cable transmission.

[0008] Preferably, the reversing plate comprises a turntable rotatably connected to the mounting bracket, two ends of the turntable are provided with limiting parts, and the cable is located between the two limiting parts.

[0009] The cable passes around the rotatable turntable, which is beneficial to reducing the friction between the cable and the reversing disk and reducing transmission loss; the limit parts at both ends are used to prevent the cable from detaching from the turntable, which is beneficial to reducing the transmission failure rate and improving the stability of the transmission.

[0010] Preferably, the transmission assembly further comprises a guide tube sleeved on the cable.

[0011] The guide tube provides a guide for the cable to bypass multiple reversing discs and connect to the slider, preventing the cable from being blocked from transmission by other components, which is beneficial to improving the stability of the cable transmission.

[0012] Preferably, the reversing disc further comprises a fixing seat fixedly connected to the mounting bracket, the turntable is rotatably connected to the fixing seat, a guide opening is provided on the fixing seat, and the guide tube is fixed to the fixing seat through the guide opening.

[0013] The fixing seat provides positioning for the turntable and the guide tube. On the one hand, the turntable is transferred from the mounting bracket to the fixing seat, which is convenient for installation, disassembly and subsequent maintenance. On the other hand, it is helpful for guiding the auxiliary guide tube so that the cable can bypass the turntable on the fixing seat.

[0014] Preferably, there are at least four reversing discs. When there are four reversing discs, the four reversing discs are respectively located at two ends of the two guide rails.

[0015] In order for the slide rail assembly located on one side to enable the slider to move along the guide rail, it is necessary to set reversing disks at both ends of the guide rail, and make the cable bypass the above two reversing disks and connect to the slider, so that a section of the cable is parallel to the guide rail to improve the smoothness when pulling the slider. Therefore, four reversing disks are conducive to realizing the cable connecting the two sliders and pulling the two sliders to move synchronously and in the same direction along the guide rail, ensuring the integrity and stability of the transmission.

[0016] Preferably, the connecting rod assembly includes a swivel arm and a screen bracket, a screen is fixedly connected to the screen bracket, one end of the swivel arm is rotatably connected to the mounting bracket, and the other end is rotatably connected to the screen bracket, and the screen bracket is rotatably connected to the slider.

[0017] When the slider moves along the guide rail, it drives the screen bracket to rotate relative to the rotating arm, and the screen bracket drives the rotating arm to rotate relative to the mounting bracket to realize the flipping process of the screen. This multi-stage rotation causes the screen bracket and the rotating arm to fold relative to each other, and adjusts the rotation angle of the screen, which is beneficial to enhancing the screen viewing angle adjustment capability and improving space utilization; the screen is installed on the screen bracket and supported by the rotating arm, which is beneficial to improve the stability of the screen and prevent jitter from affecting viewing.

[0018] Preferably, the screen bracket is provided with a connecting piece, and the screen bracket is rotatably connected to the sliding block via the connecting piece.

[0019] When the screen bracket and the slider cannot be directly connected, the connecting piece can serve as an extension of the screen bracket relative to the slider, which is conducive to achieving a rotational connection between the screen bracket and the slider.

[0020] Preferably, an adapter bracket is provided on the slider, the connecting member is rotatably connected to the adapter bracket, and the slider is fixedly connected to the cable through the adapter bracket.

[0021] As an intermediate component, the adapter bracket replaces the slider and rotates relative to the connector, which is conducive to enhancing flexibility and adaptability. On the other hand, it can be more easily installed or replaced without disassembling other components, which is conducive to installation and subsequent maintenance. When connecting the cable, the adapter bracket can also avoid directly concentrating the tension on one point, reducing wear or breakage caused by concentrated force, which is conducive to improving the stability and service life of the entire system.

[0022] Preferably, both ends of the adapter bracket can be fixedly connected to the cable, and in this case, the cable can be divided into two sections, one section connecting the two sliders and the reel, and the other section only connecting the two sliders.

[0023] A segmented cable is used to connect the two sliders, so that force can be applied to the two sections of the cable separately. When one section of the cable is worn or damaged, it can be replaced in time, which helps to reduce the time required for assembly and disassembly and facilitate subsequent maintenance.

[0024] Preferably, the transmission assembly further comprises a reducer, the output end of the rotary drive member is connected to the reducer, and the output end of the reducer is connected to the reel.

[0025] On the one hand, the reducer can control the rotation speed of the reel, which is beneficial to improve the stability of the transmission. On the other hand, it can increase the torque output to the reel, improve the load capacity of the transmission component, and further help improve the stability of the transmission.

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] Two slide rail assemblies are used to stably drive the connecting rod assembly to rotate the screen, which is beneficial to maintaining the stability of screen flipping; the connecting rod assembly is connected to the screen to provide support for the screen, which is beneficial to improving the stability of screen flipping; the transmission assembly uses a cable to bypass multiple reversing disks and connect to two sliders, and at the same time drives the sliders of the two slide rail assemblies to move synchronously in the same direction along the guide rail, which reduces transmission noise, simplifies the transmission structure, and reduces space occupancy. On the one hand, it is beneficial to improve space utilization and flexibility of structural design, and on the other hand, it is beneficial to reduce production and processing costs, facilitate subsequent maintenance, and realize stable flipping of the screen; at the same time, the use of a reversing disk is conducive to connecting the cable with the two sliders and pulling the slider to move along the guide rail, thereby improving the stability of the transmission; the use of a reel allows the rotating drive member to stably drive the winding and unwinding of the cable, which is beneficial to improving the stability of the cable transmission.

The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] In this embodiment, please refer to Figure 1 As shown, the present invention provides a vehicle-mounted screen flipping motion mechanism, which includes a mounting bracket 10, on which are provided two spaced-apart slide rail assemblies 40, a connecting rod assembly 50 connected to the slide rail assembly 40, and a transmission assembly 30, and the connecting rod assembly 50 is connected to a screen.

[0038] The slide rail assembly 40 includes a guide rail 43 and a slider 41 slidably disposed on the guide rail 43. There are two connecting rod assemblies 50, which are respectively located on one side of the two slide rail assemblies 40 and connected to the corresponding slider 41. The connecting rod assembly 50 is parallel to the slide rail assembly 40. When the slider 41 moves along the guide rail 43, it can drive the connecting rod assembly 50 to move so as to drive the rotation of the screen.

[0039] The transmission assembly 30 includes a rotating drive member 20, a reel 31, a cable 32 and a plurality of reversing disks 33. The rotating drive member 20 serves as a driving source, and its output end is connected to the reel 31 and can drive the reel 31 to rotate. A cable 32 is wound around the reel 31, and the cable 32 passes around a plurality of reversing disks 33 and is connected to a slider 41. When the rotating drive member 20 drives the reel 31 to rotate, the cable 32 can pull the two sliders 41 to move synchronously in the same direction along the guide rail 43, thereby realizing stable flipping of the screen.

[0040] In this embodiment, please refer to Figure 1 and Figure 4As shown, the reversing disk 33 is an important structure that can connect and pull the two sliders 41 after the cable 32 is wound around the reel 31. It includes a turntable 331 rotatably connected to the mounting bracket 10. Both ends of the turntable 331 are provided with limiting parts 3311. The cable 32 passes through the two limiting parts 3311 of the turntable 331. When the cable 32 is pulled by the turntable 331, the turntable 331 will rotate with the cable 32.

[0041] In addition, the turntable 331 can also be replaced by a limit column fixedly connected to the mounting bracket 10 and having a limit portion 3311, a guide roller, or a rotating wheel with a groove matching the cable 32, so that the cable 32 can be changed direction after bypassing and is not easy to fall off.

[0042] In other embodiments, the guide rail 43 may be provided with the above-mentioned structure capable of reversing the direction of the cable 32 .

[0043] For details, please refer to Figure 1 As shown, the transmission assembly 30 further includes a guide tube 34 sleeved on the cable 32 , and the guide tube 34 guides the cable 32 to extend from the reel 31 to the reversing disc 33 , or guides the cable 32 to extend from one reversing disc 33 to another reversing disc 33 .

[0044] It can be understood that there are multiple guide tubes 34, and their tubular structure can also reduce the loss caused by friction between the cable 32 and the inner wall of the guide tube 34 during transmission. The guide tube 34 can be bent to different degrees or change in length according to the design structure, so that the cable 32 can pull the two sliders 41 to move synchronously and in the same direction along the guide rail 43.

[0045] Furthermore, a channel or a tube having a lumen structure may be used instead of the guide tube 34 .

[0046] More specifically, please refer to Figure 4 As shown, the reversing disc 33 also includes a fixing seat 332 fixed on the mounting bracket 10, and the rotating disc 331 and the fixing seat 332 are rotatably connected. In this case, the rotating disc 331 can be installed only on the fixing seat 332, and the fixing seat 332 can be removed together with the rotating disc 331. The fixing seat 332 is provided with a guide opening 3321, which is used to guide and fix one end of the guide tube 34, so that the cable 32 can accurately bypass between the limiting parts 3311 at both ends of the rotating disc 331 to prevent the guide tube 34 from being separated from the guide position.

[0047] It can be understood that the fixed seat 332 has the function of positioning the turntable 331 and guiding and fixing the guide tube 34. Therefore, when the fixed seat 332 is located beside the turntable 331 and is not rotatably connected to the turntable 331, the fixed seat 332 is responsible for guiding and fixing the guide tube 34 so that the cable 32 can bypass the turntable 331.

[0048] In this embodiment, please refer to Figure 1 As shown, there are at least four reversing discs 33, which are respectively located at the two ends of the two guide rails 43. It can be understood that in order to make the cable 32 pull the slider 41 to move along the guide rail 43 to the two ends of the guide rail 43, the cable 32 needs to go around the outside of the two ends of the guide rail 43 and connect with the slider 41. Therefore, two reversing discs 33 are required for the slider 41 on one guide rail 43, and a total of four reversing discs 33 are required for the sliders 41 on the two guide rails 43. The extra reversing discs 33 can be used as auxiliary structures.

[0049] In addition, the reversing disc 33 may also be arranged outside the connecting line between the two ends of the two guide rails 43, so as to achieve the above functions.

[0050] In this embodiment, please refer to Figure 1 and Figure 3 As shown, the connecting rod assembly 50 includes a swivel arm 51 and a screen bracket 52. One end of the swivel arm 51 is rotatably connected to the mounting bracket 10, and the other end is rotatably connected to the screen bracket 52. The screen is fixedly mounted on the fixed surface of the screen bracket 52. The screen bracket 52 is rotatably connected to the slider 41. When the slider 41 moves along the guide rail 43, it drives the screen bracket 52 to rotate relative to the swivel arm 51, and the screen bracket 52 drives the swivel arm 51 to rotate relative to the mounting bracket 10. The screen bracket 52 and the swivel arm 51 are folded and form a triangular structure to realize the flipping of the screen.

[0051] It can be understood that the rotating arm 51 is bent. When the screen bracket 52 drives the rotating arm 51 to rotate relative to the mounting bracket 10, the rotating arm 51 can rotate in a specified direction, which can save design space and increase the stability of screen flipping.

[0052] Specifically, a connecting piece 53 is also provided on the screen bracket 52, and the connecting piece 53 is located on the side of the screen bracket 52 close to the slider 41. When the screen bracket 52 cannot be directly connected to the slider 41 in the initial state, the connecting piece 53 can serve as a medium for rotational connection between the screen bracket 52 and the slider 41.

[0053] It can be understood that, according to the spatial position between the screen bracket 52 and the slider 41 in the initial state, the shape and structure of the connecting member 53 can be changed so as to achieve a rotational connection between the screen bracket 52 and the slider 41 .

[0054] More specifically, please refer to Figure 1 and Figure 2As shown, a detachable adapter bracket 42 is provided on the slider 41, and the adapter bracket 42 includes a rotating portion 421 rotatably connected to the connecting member 53 and a fixed portion 422 for fixing the cable 32. The rotating portion 421 and the connecting member 53 are in a snap-on rotational connection relationship. The fixed portion 422 is provided with an opening 4221 along the track direction and a threaded hole perpendicular to the opening 4221. The cable 32 is fixed with bolts after passing through the opening 4221.

[0055] It can be understood that the rotating part 421 and the connecting member 53 can have a rotating connection relationship of any structure. Therefore, the positions of the rotating part 421 and the connecting member 53 can be set oppositely, that is, the connecting member 53 is set on the adapter bracket 42, and the corresponding rotating part 421 is set on the screen bracket 52; the function of the fixed part 422 is to fix the cable 32, so the cable 32 can also be fixed by clamping, winding, welding, etc.

[0056] In addition, when there is no adapter bracket 42 , the cable 32 and the screen bracket 52 can be directly connected to the slider 41 .

[0057] More specifically, the cable 32 can be fixed at both ends of the fixing portion 422 of the adapter bracket 42, so the cable 32 can be cut off between the two ends of the fixing portion 422 to form two sections of the cable 32. One section is wound around the reel 31 and connected to the two reversing disks 33, and the other end is only connected to the two reversing disks 33. It can be understood that the cable 32 can still pull the two sliders 41 to move synchronously and in the same direction along the guide rail 43.

[0058] It is understandable that during production and processing, two cables 32 may be directly used for assembly. In addition, the positions and structures of the two fixing portions 422 may also be changed.

[0059] In this embodiment, the rotating drive member 20 is a motor, and the transmission assembly 30 also includes a reducer 35. The reducer 35 is a worm gear reduction structure. The output end of the motor is connected to a worm, and the worm is meshed with the worm wheel to achieve torque increase and self-locking. The worm wheel is connected to the reel 31 and drives the reel 31 to rotate. It can be understood that the rotating drive member can also adopt a DC motor, a stepper motor, a servo motor, etc., and the worm gear reduction structure can also increase multi-stage gear transmission or adopt other reducer schemes to be able to increase torque and self-lock, control the rotation speed and accuracy of the reel 31, and increase the load capacity and transmission stability of the transmission assembly 30.

[0060] The specific application process of the utility model is as follows:

[0061] In the initial state, the two sliders 41 are located at one end of the same side of their respective guide rails 43, the screen bracket 52 and the rotating arm 51 do not rotate, and the screen is closed on the mounting bracket 10. When the rotary drive member 20 rotates forward, the reel 31 rotates forward to move the cable 32, and the cable 32 pulls the two sliders 41 synchronously toward the two reversing disks 33 in the same direction. The two sliders 41 move synchronously in the same direction along their respective guide rails 43, driving the screen bracket 52 to rotate relative to the slider 41. When the screen bracket 52 rotates, it also rotates with the rotating arm 51, and drives the rotating arm 51 to rotate relative to the mounting bracket 10. The screen bracket 52 and the rotating arm 51 are folded and form a triangular structure. The screen opens smoothly with the rotation of the screen bracket 52. When the rotary drive member 20 is reversed, the triangular structure between the screen bracket 52 and the rotating arm 51 is restored to the state before the rotary drive member 20 rotates forward, and the screen closes smoothly to the initial state with the rotation of the screen bracket 52.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
