Description

Technical Field

[0001] The present invention belongs to the technical field of folding screens, and in particular relates to a folding, extending and rotating control system for a vehicle-mounted folding screen. Background Art

[0002] At present, in order to display more abundant information to users, improve the efficiency of human-computer communication and enhance the user experience, the screen size of various display screens is getting larger and larger. Correspondingly, electronic equipment terminals with large screens will bring inconveniences in use and storage in certain fixed places with limited space. For example, when used in a car, the large-size screen is bulky and easily encroaches on the passengers' riding space, affecting the riding experience, and also causes a certain obstruction to the driver's line of sight. Therefore, engineers are considering applying folding screen technology to the car-mounted screen, which can extend out of the storage cavity and unfold for use; when not in use, the car-mounted screen is folded and stored in the storage cavity.

[0003] However, in actual use, the prior art has the following defects:

[0004] 1. When the screen is unfolded, it is easy to be affected by inertia or external force during vehicle bumps, causing the screen to fold by mistake. In other words, the screen cannot remain unfolded stably when disturbed by external forces.

[0005] 2. After the screen is turned on, it can only be used at a fixed angle (horizontal or vertical), and the angle of the screen cannot be freely adjusted according to the displayed content, which affects the display effect and leads to a poor user experience. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved folding, extending and rotating control system for a vehicle-mounted folding screen.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A folding, extending and rotating control system for a vehicle-mounted folding screen, the folding screen comprising a rotating shaft structure, a first module and a second module which are respectively rotatably connected to the rotating shaft structure and can be folded or unfolded relative to each other, the control system comprising a flipping unit, a folding and extending driving unit, and a rotating driving unit, wherein the flipping unit comprises a first flipping module and a second flipping module which are respectively fixedly connected to the first module and the second module; the folding and extending driving unit forms a flipping path which bends from one end toward a direction away from the folding screen, the first flipping module and the second flipping module are reciprocatingly slid along the flipping path, and under the drive of the folding and extending driving unit, the first flipping module and the second flipping module are synchronously and flipped toward each other to form a self-locking state or synchronously and flipped away from each other to form an unlocking state so as to relatively unfold or fold the first module and the second module; the rotating driving unit drives the folding screen to rotate around a rotation center line when the first module and the second module are flattened and the first flipping module and the second flipping module are self-locking, wherein the rotation center line is perpendicular to a plane formed by the unfolding of the first module and the second module.

[0009] According to a specific implementation and preferred aspect of the present invention, when the first module and the second module are relatively unfolded, the first flip module and the second flip module are spliced ​​and self-locked, and a limit groove matching the shaft structure is formed between the first flip module and the second flip module, and the shaft structure abuts against the inner wall of the limit groove. Here, the shaft structure abuts against the inner wall of the limit groove to form a limit, which not only improves the stability of the first and second flip modules in the self-locking state, but also the first and second flip modules can fit with the pivot based on the formed limit groove, effectively avoiding interference with the complete flattening of the folding screen.

[0010] Preferably, the first flip module and the second flip module each include a first block arranged in parallel with the corresponding module, and a second block vertically connected between the first block and the corresponding module, wherein the first block slides on the flipping path, and when self-locking is formed, the two first blocks and the two second blocks are spliced ​​from the end faces, and a limit groove is formed between the two second blocks. Here, the structure is simple, and it is easy to install and implement.

[0011] According to another specific implementation and preferred aspect of the present invention, the stowage and extension drive unit is used to drive the shaft structure to reciprocate along the extension direction of the rotation centerline, and the first flip module and the second flip module slide synchronously along the flip path. Here, based on the movement guidance of the first flip module and the second flip module, the movement of the shaft structure is directly driven to drive the first and second modules to be relatively flattened or folded, and the stowage and extension process is stable and efficient.

[0012] Preferably, the retraction and extension drive unit includes a guide seat forming a flipping path, a connecting module slidably connected to the guide seat along the extension direction of the rotation center line, and a retraction and extension drive for driving the connecting module to reciprocate along the extension direction of the rotation center line, wherein the connecting module is fixedly connected to the rotating shaft structure.

[0013] Specifically, the guide seat includes a seat body, a first seat body and a second seat body fixed relatively to the seat body, wherein the first seat body and the second seat body are spaced apart in the folding and expanding direction of the folding screen and form an avoidance space for avoiding the folding and expanding movement of the folding screen; guide grooves on the first seat body and the second seat body that constitute a flipping path are respectively formed on the first seat body and the second seat body, and the first flipping module and the second flipping module are correspondingly slidably connected in the guide grooves on the first seat body and the second seat body.

[0014] Furthermore, the guide grooves on the first seat body and the second seat body are symmetrically arranged about the center line of the avoidance space; and / or, the first seat body and the second seat body constitute a guide group, there are two guide groups and they are spaced apart along the extension direction of the rotating shaft structure; and / or, the guide grooves on the first seat body and the second seat body also respectively constitute a translation path connected to one end of the flipping path, wherein the extension direction of the translation path is parallel to the rotation center line of the folding screen, and under the drive of the retraction and extension drive unit, the first flip module and the second flip module maintain their relative positions unchanged and slide on the translation path, and the first module group and the second module maintain a folded state; the flipping path is arc-shaped and is tangent to the translation path from the connected end.

[0015] Preferably, the retracting and extending driver includes a power screw rod arranged on the seat body and parallel to the rotation center line, a motor driving the power screw rod to rotate around its own center line, the connecting module includes a module body slidably connected to the seat body and threadedly matched with the power screw rod, a connecting block fixedly arranged on the module body, the connecting block is fixedly connected to the rotating shaft structure, and the first flip module and the second flip module are respectively formed with an avoidance notch for avoiding the connecting block. Here, the screw drive is adopted, which has high precision and strong reliability.

[0016] Preferably, the rotation driving unit comprises a motor, and the output shaft of the motor drives the guide seat through a transmission belt and drives the folding screen to rotate.

[0017] In addition, the folding screen can rotate around the rotation center line at an angle of 0° to 90°.

[0018] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] When the folding screen of the prior art is in the unfolded state, it is easy for the screen to be accidentally folded due to inertia or external force during vehicle bumps. In other words, the screen cannot stably maintain the unfolded state when disturbed by the outside world. At the same time, after the screen is unfolded, it can only be used at a fixed angle (horizontal or vertical), and the angle of the screen cannot be freely adjusted according to the display content, which affects the display effect and leads to a poor user experience. The present application makes an overall design for the structure of the folding and rotation control system of the vehicle-mounted folding screen, ingeniously solving the shortcomings and defects of the prior art. After adopting the control system, when the screen is unfolded, the first flip module and the second flip module are driven by the folding and unfolding drive unit to synchronously slide along the flipping path and flip towards each other to form a self-locking, and the first module and the second module in the folding screen are then relatively unfolded around the rotating shaft structure; when the screen is rotated, based on the flattening of the first module and the second module and the self-locking of the first flip module and the second flip module, the folding screen is driven to rotate around the rotation center line by the rotation drive unit; when the screen is folded, the first flip module and the second flip module are driven by the folding and unfolding drive unit to synchronously slide along the flipping path and flip towards each other to form an unlocking, and the first module and the second module in the folding screen are then relatively folded around the rotating shaft structure. Therefore, compared with the prior art, the present invention, on the one hand, uses the motion guidance formed by the first and second flip modules along the flipping path to enable the folding screen to be flattened under the self-locking of the first and second flip modules, thereby effectively improving the anti-interference performance of the folding screen and ensuring the unfolding stability of the folding screen. At the same time, the unfolding and folding process of the folding screen is smooth and efficient. On the other hand, the folding screen is driven to rotate by the rotary drive unit to meet the multi-angle use of the folding screen and improve the user experience.

[0035] like Figures 1 to 5 As shown, the vehicle-mounted folding screen extension and rotation control system involved in this embodiment includes a flip unit 1, an extension and retraction drive unit 2 for driving the folding screen P to extend and retract, and a rotation drive unit 3 for driving the folding screen P to rotate around a rotation center line.

[0036] The folding screen P of this embodiment includes a hinge structure P0, a first module P1 and a second module P2 which are respectively rotatably connected to the hinge structure P0 and can be folded or unfolded, wherein the rotation centerline of the folding screen P is perpendicular to the plane formed by the unfolding of the first module P1 and the second module P2.

[0037] Specifically, the flip unit 1 includes a first flip module 11 and a second flip module 12 which are fixedly connected to the first module P1 and the second module P2 respectively, wherein when the first module P1 and the second module P2 are relatively unfolded, the first flip module 11 and the second flip module 12 are spliced ​​and self-locked, and a limit groove c matching the rotating shaft structure P0 is formed between the first flip module 11 and the second flip module 12, and the rotating shaft structure P0 abuts against the inner wall of the limit groove c. Here, the limit is formed by the rotating shaft structure abutting against the inner wall of the limit groove, which not only improves the stability of the first and second flip modules in the self-locking state, but also the first and second flip modules can fit with the pivot based on the formed limit groove, effectively avoiding interference with the complete flattening of the folding screen.

[0038] For the convenience of implementation, the first flip module 11 and the second flip module 12 each include a first block a1 arranged parallel to the corresponding module, and a second block a2 vertically connected between the first block a1 and the corresponding module. When self-locking is formed, the two first blocks a1 and the two second blocks a2 are spliced ​​from the end faces, and a limiting groove c is formed between the two second blocks a2.

[0039] In this example, the folding and unfolding driving unit 2 forms a flipping path s that bends from one end toward a direction away from the folding screen P. The first blocks a1 in the first flipping module 11 and the second flipping module 12 are respectively arranged to slide back and forth along the flipping path s, and under the drive of the folding and unfolding driving unit 2, the first flipping module 11 and the second flipping module 12 are synchronously and flipped toward each other to form a self-locking state, or are synchronously and flipped away from each other to form an unlocking state so as to relatively unfold or fold the first module P1 and the second module P2.

[0040] For further convenience of implementation, the stowage and extension drive unit 2 is used to drive the shaft structure P0 to reciprocate along the extension direction of the rotation centerline, and the first flip module 11 and the second flip module 12 slide synchronously along the flip path s. Here, based on the movement guidance of the first flip module and the second flip module, the movement of the shaft structure is directly driven to drive the first and second modules to be relatively flattened or folded, and the stowage and extension process is stable and efficient.

[0041] In some specific embodiments, the retraction and extension drive unit 2 includes a guide seat 20 that forms a flipping path s, a connecting module 21 that is slidably connected to the guide seat 20 along the extension direction of the rotation centerline, and a retraction and extension drive 22 for driving the connecting module 21 to reciprocate along the extension direction of the rotation centerline, wherein the connecting module 21 is fixedly connected to the rotating shaft structure P0.

[0042] The guide seat 20 includes a seat body 200, a first seat body 201 and a second seat body 202 fixed relatively to the seat body 200, wherein the first seat body 201 and the second seat body 202 are spaced apart in the folding and expanding direction of the folding screen and form an avoidance space q for avoiding the folding and expanding movement of the folding screen P; guide grooves constituting a flipping path s are respectively formed on the first seat body 201 and the second seat body 202, and the first flipping module 11 and the second flipping module 12 are respectively slidably connected in the corresponding guide grooves; the guide grooves on the first seat body 201 and the second seat body 202 are symmetrically arranged about the center line of the avoidance space q; the first seat body 201 and the second seat body 202 constitute a guide group, and there are two guide groups and they are spaced apart along the extension direction of the rotating shaft structure P0. At the same time, the guide grooves on the first base 201 and the second base 202 also respectively form a translation path s0 connected to one end of the flip path s, wherein the extension direction of the translation path s0 is parallel to the rotation centerline of the folding screen P, and the flip path s is arc-shaped and tangent to the translation path s0 from the connected end. Driven by the folding and unfolding driving unit 33, the first flip module 11 and the second flip module 12 slide on the translation path s0 while maintaining the relative position unchanged, and the first module P1 and the second module P2 remain in a folded state. By setting the translation path, the folding screen moves inward along the translation path when it is in a folded state.

[0043] The retracting and extending driver 22 includes a power screw 220 arranged on the seat body 200 and parallel to the rotation center line, and a motor 221 driving the power screw 220 to rotate around its own center line. The connecting module 21 includes a module body 210 slidably connected to the seat body 200 and threadedly matched with the power screw 220, and a connecting block 211 fixedly arranged on the module body 210. The connecting block 211 is fixedly connected to the rotating shaft structure P0. The first flip module 11 and the second flip module 12 are respectively formed with avoidance gaps for avoiding the connecting block 211. Here, screw drive is adopted, which has high precision and strong reliability.

[0044] In addition, the rotation drive unit 3 drives the folding screen to rotate around the rotation center line when the first module P1 and the second module P2 are flattened and the first flip module 11 and the second flip module 12 are self-locked; the rotation drive unit 3 includes a motor 30, and the output shaft of the motor 30 drives the guide seat 20 through a transmission belt and drives the folding screen to rotate; the rotation angle of the folding screen around the rotation center line is 0°~90°.

[0045] In summary, after adopting the control system, when unfolding the screen, the first flip module and the second flip module are driven by the folding and unfolding driving unit to synchronously slide along the flipping path and flip towards each other to form a self-locking, and the first module and the second module in the folding screen are relatively unfolded around the rotating shaft structure; when rotating the screen, based on the flattening of the first module and the second module and the self-locking of the first flip module and the second flip module, the folding screen is driven by the rotating driving unit to rotate around the rotation center line; when folding the screen, the first flip module and the second flip module are driven by the folding and unfolding driving unit to synchronously slide along the flipping path and flip away from each other to form an unlocking, and the first module and the second module in the folding screen are relatively folded around the rotating shaft structure. Therefore, compared with the prior art, the present invention, on the one hand, through the motion guide formed by the first and second flip modules along the flipping path, enables the folding screen to be flattened under the self-locking of the first and second flip modules, effectively improves the anti-interference performance of the folding screen, ensures the unfolding stability of the folding screen, and at the same time, the unfolding and folding process of the folding screen is smooth and efficient; on the other hand, the folding screen is driven to rotate by the rotating driving unit to meet the multi-angle use of the folding screen and improve the user experience.

[0046] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them.
