Description

Technical Field

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

[0002] With the development of science and technology, more and more new energy multi-functional vehicles have been launched in the automobile market, and people's requirements for the ride comfort and functions of automobiles are getting higher and higher. The appearance of the central control screen in the front row of the car has also aroused people's enthusiastic praise and love, so there is a demand for the use of touch screens in the back row. However, as the functions of the car become more and more, the available space in the car has also become less. Although there are rear flip screens and corresponding flip devices on the market, their screens are flipped through physical axes, so that when the screen starts to move, it needs to be translated for a distance to make way, so as to avoid interference with the base or other structures when the screen flips. However, this setting method requires a certain space to be reserved inside the base for the installation and translation of the physical axis, which makes the space utilization rate of the overall structure low, resulting in a large volume of the flip device, which occupies more space in the car; in addition, the physical axis structure is difficult to provide a constant damping force for the screen, resulting in a large shaking amplitude of the screen during the flipping process, and when the screen is flipped and used, it is also easy to shake, and the stability is poor, which seriously affects the passenger experience. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a screen flipping motion device which occupies a small space and has high stability.

[0004] The purpose of this application is achieved through the following technical solutions:

[0005] A screen flipping motion device comprises a display screen, a mounting bracket for mounting the display screen, and a base for mounting the mounting bracket, wherein sliding grooves are provided on both sides of the base, a slider is slidably mounted in the sliding groove, both sides of the mounting bracket are connected to the slider, the mounting bracket is provided with arc teeth and a damping spring, the base is provided with a driving motor and a damping slide groove, the output end of the driving motor is connected to the arc teeth, the damping spring is slidably mounted in the damping slide groove and abuts against the bottom of the damping slide groove.

[0006] In the above technical solution, the display screen is installed on the mounting bracket, the back of the mounting bracket is provided with arc-shaped teeth, the output end of the driving motor is provided with a driving gear, the arc-shaped teeth are meshed with the driving gear, and the driving motor rotates the display screen by driving the arc-shaped teeth to move, and the two sides of the mounting bracket are connected to the sliders in the sliding groove, and the sliding groove is arc-shaped. When the mounting bracket and the display screen rotate, the slider slides along the arc-shaped sliding groove, wherein the bottom of the mounting bracket is provided with an elastic damping spring sheet, and the damping spring sheet is slidably installed in the damping sliding groove and is always in a compressed state. When the mounting bracket rotates, the damping spring sheet moves along the damping sliding groove. Since the damping spring is always in a compressed state, during the movement of the mounting bracket, the damping spring can always provide a constant friction damping force and holding force for the mounting bracket, so that the display screen can always move smoothly at a state greater than its own gravity during the movement, effectively improving the stability during the movement, and combined with the restrictions of the sliders and sliding grooves on both sides, the display screen can move smoothly along the preset rotation path, and after the display screen is moved into place, the holding force provided by the damping spring can also keep the display screen stable at the set angle, and it will not shake easily, thereby effectively improving the user experience.

[0007] It should be noted that when the display screen of the present application rotates, its rotation axis is located on the outside of the base, that is, the display screen always rotates around a virtual axis located on the outside of the base. Since there is no need to design a physical axis connected to the display screen, the display screen can be flipped in a manner closer to the inside of the base, and there is no need to translate a certain distance to make way before rotating. Therefore, compared with the existing flipping device driven by a physical axis, the present application has a more compact structure, a smaller size, and occupies less space in the vehicle.

[0009] In the above technical solution, the two sliding grooves on each side of the base are arc-shaped and arranged at intervals up and down. The protruding sliding parts at both ends of the sliding block are respectively installed in the two sliding grooves. By setting two sliding grooves, the stability of the slider during movement can be enhanced, thereby improving the stability of the display screen when it is flipped.

The protrusion will touch the contact of the trigger switch when moving. At this time, the trigger switch transmits a signal to the control program, and the control program is used to detect whether the display screen has moved into place.

[0012] Optionally, in a possible implementation manner, a control circuit board is provided between the two slots, and the trigger switch is mounted on the control circuit board.

[0013] In the above technical solution, the control circuit board is located in the gap between the two slots, the trigger switch is installed on the control circuit board and electrically connected to the control circuit board, and the signal transmitted by the trigger switch is transmitted to the control program via the control circuit board to detect whether the display screen has moved into place. At the same time, the control program can also receive the stall signal of the drive motor itself, and make a judgment together with the signal of the trigger switch to ensure that the display screen will not be out of place.

[0014] Optionally, in a possible implementation manner, a sliding seat is installed on the base, and the damping slide groove is arranged on the top of the sliding seat.

[0015] In the above technical solution, the damping groove is made to have a certain height compared to the base through the sliding seat, which is convenient for the installation of the damping spring and makes it easy to keep the damping spring in a compressed state at all times, thereby ensuring the stable provision of the damping force. At the same time, a detachable sliding seat is provided, and there is no need to groove the base, which will not change the structure of the base and simplify the processing process.

[0016] Optionally, in a possible implementation, a clutch assembly is provided on the base, and the clutch assembly includes a clutch shaft, and a first transmission gear and a second transmission gear installed on the clutch shaft, the first transmission gear is connected to the output end of the drive motor, and the second transmission gear is meshed with the arc teeth.

[0017] In the above technical solution, the driving motor drives the first transmission gear to rotate, thereby driving the clutch shaft and the second transmission gear installed on the clutch shaft to rotate, so that the mounting bracket and the display screen thereon are flipped.

[0018] Optionally, in a possible implementation, a sleeve is also installed on the clutch shaft, one end of the sleeve is connected to the second transmission gear, the sleeve includes a limit ring, an elastic member and a friction plate unit, one side of the first transmission gear is connected to a mounting block, the interior of the mounting block is provided with a cavity for accommodating the friction plate unit, the friction plate unit is installed in the cavity of the mounting block, and the two ends of the elastic member are respectively against the limit ring and the friction plate unit.

[0019] In the above technical solution, the sleeve is sleeved on the clutch shaft, a protruding limit ring is provided at one end of the sleeve body, and a friction plate unit is provided at the other end, the elastic member is located between the limit ring and the friction plate unit, and its two ends are against the limit ring and the friction plate unit, wherein the second transmission gear and the clutch shaft are interference fit, and the drive motor drives the first transmission gear to rotate, thereby driving the friction plate unit connected to the mounting block to rotate, thereby transmitting power to the sleeve and the second transmission gear, so that when the display screen is impacted by external force, the impact on the output end of the drive motor is reduced, thereby effectively protecting the drive motor.

[0020] Optionally, in a possible embodiment, the friction plate unit includes a plurality of first friction plates and second friction plates arranged in parallel, the first friction plates and the second friction plates are staggered, a plurality of mounting protrusions are provided on the outer periphery of the first friction plate, and a mounting groove matching the mounting protrusions is provided on the inner side of the mounting block.

[0021] In the above technical solution, the first friction plate is meshed with the mounting block through the mounting protrusion. When the display screen in the open state is subjected to a large external force impact, the impact force will cause the second transmission gear to rotate under the influence of the arc teeth and drive the shaft sleeve to rotate. At this time, since the driving motor is in a locked state, the first transmission gear connected to the output end of the driving motor is in an inactive state, and the first friction plate connected to the mounting block of the first transmission gear is also inactive. At this time, the first friction plate and the second friction plate need to overcome the elastic force of the elastic member, so the second friction plate and the first friction plate rotate relative to each other, thereby preventing the output end of the driving motor from being subjected to a large impact. The friction damping generated by the relative rotation of the first friction plate and the second friction plate plays a clutch role, thereby effectively protecting the driving motor. Moreover, since friction damping is generated, the sound of misaligned teeth collision will not be generated.

[0022] Optionally, in a possible implementation manner, mounting seats are provided on both axial sides of the clutch shaft, the mounting seats are mounted on the base, and both ends of the clutch shaft are rotatably mounted in the mounting seats.

By providing the mounting seat, it is convenient to disassemble and assemble the clutch assembly, which is beneficial to the maintenance and care of the clutch assembly.

[0024] Compared with the prior art, the beneficial effects of this application are:

[0025] The present application uses arc-shaped teeth arranged on the mounting bracket, and sliding grooves and slider structures on both sides of the base, so that when the display screen rotates, its rotation axis is located on the outside of the base, that is, the display screen always rotates around a virtual axis located on the outside of the base. Compared with the existing flip device driven by a physical axis, the structure is more compact, the volume is smaller, and the space occupied in the vehicle is also less; in addition, the present application is provided with matching damping springs and damping slide grooves. When the display screen rotates, the damping springs can always provide a constant friction damping force and holding force for the mounting bracket, so that the display screen can always move smoothly at a state greater than its own gravity during the movement, effectively improving the stability during the movement, so that the display screen can move smoothly according to the preset rotation path, and after the display screen moves into place, the holding force provided by the damping spring can also keep the display screen stable at the set angle, and it will not shake easily, thereby effectively improving the user experience.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0043] Please refer to Figures 1 to 11 The present embodiment provides a screen flipping motion device for the flipping motion of a vehicle-mounted touch screen, which includes a display screen 1, a mounting bracket 2 for mounting the display screen 1, and a base 3 for mounting the mounting bracket 2. Sliding grooves 33 are provided on both sides of the base 3, and a slider 34 is slidably installed in the sliding groove 33. Both sides of the mounting bracket 2 are connected to the slider 34. The mounting bracket 2 is provided with an arc tooth 21 and a damping spring 22. The base 3 is provided with a driving motor 31 and a damping slide groove 321. The output end of the driving motor 31 is connected to the arc tooth 21. The damping spring 22 is slidably installed in the damping slide groove 321 and abuts against the bottom of the damping slide groove 321.

[0044] In this embodiment, the display screen 1 is mounted on the mounting bracket 2. The back of the mounting bracket 2 is provided with an arc-shaped tooth 21. The output end of the driving motor 31 is provided with a driving gear 311. The arc-shaped tooth 21 meshes with the driving gear 311. The driving motor 31 drives the arc-shaped tooth 21 to move to rotate the display screen 1. The two sides of the mounting bracket 2 are connected to the slider 34 in the sliding groove 33. The sliding groove 33 is arc-shaped. When the mounting bracket 2 and the display screen 1 rotate, the slider 34 slides along the arc-shaped sliding groove 33. The bottom of the mounting bracket 2 is provided with an elastic damping spring sheet 22. The damping spring sheet 22 is slidably installed in the damping sliding groove 321 and is always in a compressed state. When the mounting bracket 2 rotates, The damping spring 22 moves along the damping slide groove 321. Since the damping spring 22 is always in a compressed state, during the movement of the mounting bracket 2, the damping spring 22 can always provide a constant friction damping force and holding force for the mounting bracket 2, so that the display screen 1 can always move smoothly at a state greater than its own gravity during the movement, effectively improving the stability during the movement, and combined with the restrictions of the sliders 34 and the sliding grooves 33 on both sides, the display screen 1 can move smoothly along the preset rotation path, and after the display screen 1 is moved into place, the holding force provided by the damping spring 22 can also keep the display screen 1 stably at the set angle, and it will not shake easily, thereby effectively improving the user experience.

[0045] It should be noted that when the display screen 1 of the present application rotates, its rotation axis is located on the outside of the base 3, that is, the display screen 1 always rotates around a virtual axis Z located outside the base 3. Since there is no need to design a physical axis connected to the display screen 1, and there is no need to install a physical axis in the base 3, the display screen 1 can be flipped in a manner closer to the inside of the base 3, and there is no need to translate a certain distance to make way before rotating. Therefore, compared with the existing flipping device driven by a physical axis, the present application has a more compact structure, a smaller size, and occupies less space in the vehicle.

[0046] Specifically, Fig.11As shown in the direction, when the damping spring 22 moves to the right side of the damping slot 321 (the same applies to other positions), X is the direction of the holding force of the display screen 1, Y is the direction of the friction damping force, and Z is the virtual axis when the display screen 1 rotates. The constant friction damping force and the holding force of the display screen 1 provided by the damping spring 22 enable the display screen 1 to always move smoothly in a state greater than its own gravity during the movement, thereby improving stability.

Both ends of the slider 34 are provided with protruding sliding parts 341, and the two sliding parts 341 are slidably installed in the two sliding grooves 33 respectively. The two sliding grooves 33 are both arc-shaped and are spaced apart from each other. By providing two sliding grooves 33, the stability of the slider 34 during movement can be enhanced, thereby improving the stability of the display screen 1 when it is flipped.

The cam 332 is provided with a plurality of protrusions 342 and a plurality of protrusions 342 are provided on the cam 332.

[0049] Specifically, since the sliding grooves 33 on both sides of the base 3 are symmetrically arranged, it is only necessary to set it on one side of the base 3 to meet the detection of the placement of the display screen 1. Therefore, in this embodiment, a trigger switch 35 is only set on one side of the base 3, and not on the other side.

[0050] Please refer to Figure 6 to Figure 7Furthermore, in the present embodiment, a control circuit board 36 is provided in the interval between the two slots 331, and the trigger switch 35 is mounted on the control circuit board 36. The control circuit board 36 is located in the interval between the two slots 331. The trigger switch 35 is mounted on the control circuit board 36 and is electrically connected to the control circuit board 36. The signal transmitted by the trigger switch 35 is transmitted to the control program via the control circuit board 36 to detect whether the display screen 1 has moved into place. At the same time, the control program can also receive the stall signal of the drive motor 31 itself, and make a judgment together with the signal of the trigger switch 35 to ensure that the display screen 1 will not be out of place.
