Description

Technical Field

[0001] The present invention belongs to the technical field of folding screens, and specifically relates to an integrated machine for unfolding, folding and rotating a vehicle-mounted folding screen. Background Art

[0002] Nowadays, it is popular to install large-size screens in cars. However, in a car with limited space, large-size screens are bulky and easily occupy the passengers' riding space, affecting the riding experience. They will also block the driver's line of sight to a certain extent. Therefore, engineers are considering applying folding screen technology to the car screen. The car screen can extend out of the storage cavity and unfold for use; when not in use, the car screen is folded and put into the storage cavity for storage.

[0003] However, in actual use, the prior art is prone to the following defects:

[0004] 1. When the screen is retracted or extended, it is easy to vibrate with the shaking of the car body, resulting in poor stability and affecting the retraction and extension texture of the screen;

[0005] 2. When the screen is unfolded, it is easy for the screen to be accidentally folded due to inertia or external interference during vehicle bumps. In other words, the screen cannot remain unfolded stably when disturbed by external forces.

[0006] 2. The screen 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

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved integrated machine for unfolding, folding and rotating a vehicle-mounted folding screen.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A vehicle-mounted folding screen unfolding, folding and rotating integrated machine, comprising a machine base with an inlet and outlet, a folding screen, and a power assembly, wherein the folding screen comprises a first screen group and a second screen group connected by a pivot rotation and capable of being folded or flattened; the power assembly comprises a first motion module and a second motion module respectively fixedly connected to the first screen group and the second screen group, a folding and unfolding power device, and a rotating power device, wherein the folding and unfolding power device has a first motion path and a second motion path that are connected, the first motion path extends along the direction of entering and exiting the machine base, and the second motion path is bent from the end of the first motion path and bent inwardly, under the drive of the folding and unfolding power device, the first motion module and the second motion module maintain relative positions and slide on the first motion path unchanged, and when the first motion module and the second motion module slide in the second motion path, the first motion module and the second motion module are synchronously and flipped toward each other to form a self-locking or synchronously and flipped away from each other to form an unlocking so as to relatively flatten or fold the first screen group and the second screen group; the rotating power device drives the folding screen to rotate around the center line of the entry and exit direction when the pivot is parallel to the inlet and outlet, the first screen group and the second screen group are flattened, and the first motion module and the second motion module are self-locking.

[0010] According to a specific implementation and preferred aspect of the present invention, the retracting and extending power device is used to drive the pivot to reciprocate along the in-and-out direction, and the first motion module and the second motion module slide synchronously along the first motion path or the second motion path. Here, based on the motion guidance of the first motion module and the second motion module, the first and second screen groups are relatively flattened or folded by directly driving the movement of the pivot, and the retracting and extending process is stable and efficient.

[0011] Preferably, when forming a self-locking state, the first motion module and the second motion module are spliced ​​to form a limit groove matching the pivot, and the pivot abuts against the inner wall of the limit groove. Here, the limit is formed by the pivot abutting against the inner wall of the limit groove, which not only improves the stability of the first and second motion modules in the self-locking state, but also the first and second motion modules can fit with the pivot based on the formed limit groove, effectively avoiding interference with the complete flattening of the folding screen.

[0012] Specifically, the first motion module and the second motion module each include a first block arranged in parallel with the corresponding screen group, and a second block vertically connected between the first block and the corresponding screen group, wherein the first block slides on the first motion path or the second motion 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.

[0013] According to another specific implementation and preferred aspect of the present invention, the retraction and extension power device includes a power base forming a first motion path and a second motion path, a transmission module slidably connected to the power base along the entry and exit direction, and a retraction and extension power member for driving the transmission module to reciprocate along the entry and exit direction, wherein the transmission module is fixedly connected to a pivot.

[0014] Preferably, a storage slot extending along the inlet and outlet direction and connected to the inlet and outlet is formed on the power seat, and the first screen group and the second screen group are relatively folded and accommodated in the storage slot. Here, the inlet and outlet movement of the folding screen is guided by the storage slot, and at the same time, when the folding screen is retracted, the stability of the folding screen can be enhanced and the interference of the bumps of the external vehicle can be reduced.

[0015] Preferably, the first motion path and the second motion path constitute a path group, wherein there are two path groups, the first motion module and the second motion module are slidingly connected to the two path groups in a one-to-one correspondence, and the storage slot is located between the two path groups.

[0016] Specifically, the two path groups are symmetrically arranged about the center line of the storage slot.

[0017] Preferably, the power seat includes a seat bar extending along the in-and-out direction, two side panels fixedly connected to the seat bar on opposite sides to form a storage slot, a first guide bar and a second guide bar fixedly connected to the inner wall of each side panel and located on opposite sides of the storage slot, wherein the first guide bar and the second guide bar respectively form a first guide groove constituting a first motion path and a second guide groove constituting a second motion path, and the first motion module is correspondingly slidably connected to the first guide groove or the second guide groove on the first guide bar from opposite sides, and the second motion module is correspondingly slidably connected to the first guide groove or the second guide groove on the second guide bar from opposite sides. Here, the structure is simple and easy to assemble.

[0018] Preferably, the retracting and extending power member includes a power screw rod arranged on the seat bar and extending along the in-and-out direction, a motor driving the power screw rod to rotate around its own center line, and the transmission module includes a module body slidably connected to the seat bar and threadedly matched with the power screw rod, a connecting block fixedly arranged on the module body and located between the two side plates, the connecting block is fixedly connected to the pivot, and the first motion module and the second motion module are respectively formed with an avoidance notch for avoiding the connecting block. Here, the screw rod transmission is adopted, which has high precision and strong reliability.

[0019] Preferably, the rotary power device comprises a motor whose output shaft is connected to a power seat; and / or, the folding screen rotates around a center line of the in-and-out direction at an angle of 0° to 90°.

[0020] According to another specific implementation and preferred aspect of the present invention, the base includes a base body with an inlet and outlet formed thereon, a door panel movably connected to the base body and matching the inlet and outlet, and a driving member, wherein the driving member includes a driving wheel, one or more driven wheels, and a transmission belt that passes through the driving wheel and the driven wheel in sequence, and the transmission belt has a connecting section extending along the movement direction of the door panel, the door panel is fixedly connected to the connecting section, and the inlet and outlet are synchronously opened or closed with the transmission of the transmission belt. Here, based on the coordinated transmission of the driving wheel, the driven wheel and the transmission belt, the door panel automatically opens or closes the inlet and outlet, thereby avoiding contact with the folding screen, ensuring that the folding screen is smoothly extended or retracted, and at the same time greatly improving the closure degree of the door panel to the inlet and outlet, and reducing the probability of foreign matter entering the inside of the base. It should be particularly noted that during the process of unfolding, folding and rotating the vehicle-mounted folding screen of the present application, the first motion module and the second motion module are always on the inner side of the door panel, that is, when the vehicle-mounted folding screen extends out of the inlet and outlet and is in any state, the first and second motion modules connected to the vehicle-mounted folding screen are always hidden inside the base.

[0021] Preferably, the door panel is arranged on the inner wall of the seat body and is arranged to reciprocate along the width direction of the inlet and outlet; and / or, the driving member further comprises a base, wherein the base is formed with two connecting ears spaced apart along the movement direction of the door panel, the driven wheels have two and are correspondingly connected to the two connecting ears, and the transmission belt between the two driven wheels forms a connecting section, and the connecting line between the driving wheel and the two driven wheels forms a triangle; the base is also formed with an adjustment groove extending in a direction perpendicular to the connecting section, and the driving wheel can be adjusted along the adjustment groove to approach or move away from the connecting section and fixed on the base. Here, it is convenient to adjust the surface tension of the transmission belt to match the wear degree of the transmission belt and extend the service life.

[0022] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] Existing screens are prone to vibrate as the vehicle body sways during the process of retraction or extension, resulting in poor stability and affecting the texture of the screen when it is retracted or extended. When the screen is in the unfolded state, it is easy to be affected by inertia during vehicle bumps or external forces, causing the screen to fold incorrectly. In other words, the screen cannot stably maintain the unfolded state when affected by external interference. At the same time, after the screen is opened, 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 integrated machine for unfolding, folding and rotating the vehicle-mounted folding screen, which ingeniously solves the shortcomings and defects of the prior art. After adopting the integrated machine, under the drive of the folding and unfolding power device, the first motion module and the second motion module maintain their relative positions and slide on the first motion path, and then the first motion module and the second motion module enter and slide on the second motion path and synchronously flip towards each other to form a self-locking, and the first screen group and the second screen group then extend outward and gradually unfold to be flattened to realize the unfolding and use of the folding screen; at the same time, when the pivot is parallel to the inlet and outlet, the first screen group and the second screen group are flattened and the first motion module and the second motion module are self-locking, the rotating power device drives the folding screen to rotate around the center line of the entry and exit direction to adjust the use angle of the folding screen; in addition, under the drive of the folding and unfolding power device, the first motion module and the second motion module slide on the second motion path and synchronously flip towards each other to form an unlocking, and then the first motion module and the second motion module enter and slide on the first motion path, and the first screen group and the second screen group then gradually fold and retract to realize the folding of the folding screen. Therefore, compared with the prior art, the present invention, on the one hand, uses the motion guide formed by the first and second motion modules along the first and second motion paths to enable the folding screen to be flattened under the self-locking of the first and second motion 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 power device to meet the multi-angle use of the folding screen and improve the user experience.

Here, based on the coordinated transmission of the driving wheel, the driven wheel and the transmission belt, the door panel automatically opens or closes the inlet and outlet, thereby avoiding contact with the folding screen, ensuring that the folding screen is smoothly extended or retracted, and at the same time greatly improving the sealing degree of the door panel to the inlet and outlet, reducing the probability of foreign matter entering the inside of the base.

[0042] For the convenience of implementation, the driving member 12 also includes a base 123, wherein the base 123 is formed with two connecting ears b0 spaced apart along the moving direction of the door panel 11, the driven wheel 121 has two and correspondingly rotatably connected to the two connecting ears b0, and the transmission belt between the two driven wheels 121 forms a connecting section a, and the connecting line between the driving wheel 120 and the two driven wheels 121 forms a triangle; the base 123 is also formed with an adjustment groove b1 extending in a direction perpendicular to the connecting section a, and the driving wheel 120 can be adjusted along the adjustment groove b1 to approach or move away from the connecting section a and fixed on the base 123. Here, the surface tension of the transmission belt is conveniently adjusted to match the wear degree of the transmission belt and extend the service life.

[0043] In this example, the folding screen 2 includes a first screen group 21 and a second screen group 22 which are rotatably connected via a pivot 20 and can be folded or unfolded.

[0044] In this example, the power assembly 3 includes a first motion module 31 and a second motion module 32, which are respectively fixedly connected to the first screen group 21 and the second screen group 22, a retracting and extending power device 33, and a rotating power device 34, wherein the retracting and extending power device 33 has a first motion path s1 and a second motion path s2 that are connected, the first motion path s1 extends along the direction of entering and exiting the base 1, and the second motion path s2 is bent from the end of the first motion path s1 and bent inwardly.

Here, the pivot abuts against the inner wall of the limit groove to form a limit, which not only improves the stability of the first and second motion modules in the self-locking state, but also the first and second motion modules can fit with the pivot based on the formed limit groove, effectively avoiding interference with the complete flattening of the folding screen.

[0047] In some specific embodiments, the first motion module 31 and the second motion module 32 each include a first block d1 arranged parallel to the corresponding screen group, and a second block d2 vertically connected between the first block d1 and the corresponding screen group, wherein the first block d1 slides on the first motion path s1 or the second motion path s2, and when self-locking is formed, the two first blocks d1 and the two second blocks d2 are spliced ​​from the end faces, and a limiting groove c is formed between the two second blocks d2.

The transmission module 331 includes a module body f0 that is slidably connected to the seat bar e0 and threadedly matched with the power screw g0, and a connecting block f1 that is fixedly arranged on the module body f0 and located between the two side panels. The connecting block f1 is fixedly connected to the pivot 20, and avoidance gaps for avoiding the connecting block f1 are respectively formed on the first motion module 31 and the second motion module 32.

[0052] In addition, the rotary power device 34 includes a motor 340 whose output shaft is connected to the power seat 330, and the motor 340 drives the power seat 330 to rotate and drives the folding screen 2 to rotate around the center line of the entry and exit direction at an angle of 0° to 90°.

[0053] In summary, after adopting the all-in-one machine, driven by the retracting and extending power device, the first motion module and the second motion module maintain their relative positions and slide on the first motion path, and then the first motion module and the second motion module enter and slide on the second motion path and synchronously flip towards each other and approach to form a self-locking, and the first screen group and the second screen group extend outward and gradually unfold to be flattened to realize the unfolding and use of the folding screen; at the same time, when the pivot is parallel to the inlet and outlet, the first screen group and the second screen group are flattened and the first motion module and the second motion module are self-locking, the rotary power device drives the folding screen to rotate around the center line of the entry and exit direction to adjust the use angle of the folding screen; in addition, driven by the retracting and extending power device, the first motion module and the second motion module slide on the second motion path and synchronously flip towards each other and away to form an unlocking, and then the first motion module and the second motion module enter and slide on the first motion path, and the first screen group and the second screen group gradually fold and retract to realize the folding of the folding screen. Therefore, compared with the prior art, the present invention, on the one hand, uses the motion guidance formed by the first and second motion modules along the first and second motion paths to enable the folding screen to be flattened under the self-locking of the first and second motion 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 a rotary power device to meet the multi-angle use of the folding screen and improve the user experience. On the third aspect, based on the motion guidance of the first motion module and the second motion module, the movement of the pivot is directly driven to drive the first and second screen groups to be relatively flattened or folded, and the folding and unfolding process is stable and efficient.
