Abstract
Description
Technical Field

[0002] At present, vehicle-mounted flip screens, especially rear-row flip screens, are widely used. The rear-row flip screens are installed on the roof of the vehicle. The rear-row flip screens installed on the roof can provide a more comfortable viewing angle for rear passengers, thereby improving the user experience. As the screen size increases, the requirements for the output power of the flip mechanism are getting higher and higher. Common vehicle-mounted flip mechanisms generally use a single motor drive to provide flip power, or use a connecting rod mechanism to complete sliding and opening and closing at the same time.

[0031] According to some embodiments of the present application, referring to Figures 1 to 5 As shown, Figure 1 This is a schematic diagram of the structure of the vehicle-mounted sliding screen in the open state of an embodiment of the present application. Figure 2 This is an exploded view of the structure of the vehicle-mounted slide screen of the embodiment of the present application. Figure 3 This is a bottom view of the vehicle-mounted slide screen in the folded state according to the embodiment of the present application. Figure 4 This is a left view of the vehicle-mounted slide screen of the embodiment of the present application when it is folded up. Figure 5It is a front view of the vehicle-mounted slide screen of the embodiment of the present application in the folded state. The vehicle-mounted slide screen of the embodiment of the present application includes: a first mounting frame 1, a second mounting frame 2, a screen 11, a first guide rail 8, a first driving device 3 and a translation mechanism, the first mounting frame 1 and the second mounting frame 2 are used to be arranged on the vehicle ceiling in parallel and spaced along the first direction, and the first mounting frame 1 and the second mounting frame 2 are both extended along the first direction; the screen 11 is arranged between the first mounting frame 1 and the second mounting frame 2; the first guide rail 8 is arranged on the first mounting frame 1 and extends along the first direction; the first driving device 3 is slidably matched with the first guide rail 8, and the driving shaft of the first driving device 3 is connected to one side of the top of the screen 11, which is used to drive the screen 11 to flip vertically; the translation mechanism includes a second driving device and a transmission unit 5, the second driving device is arranged on the second mounting frame 2, the second driving device and the transmission unit 5 are transmission-connected, the second driving device is used to drive the transmission unit 5 to move along the first direction, and the transmission unit 5 is rotationally connected to the other side of the top of the screen 11.
[0032] Specifically, the "first guide rail 8" here refers to a component that can act as a sliding conductor, which can be in the shape of a guide rod. The first drive device 3 is mounted on the first guide rail 8, so that the first drive device 3 can slide on the first guide rail 8; it can also be in the shape of a slide groove, so that a part of the first drive device 3 is slidably embedded in the slide groove.
[0033] The first mounting frame 1 and the second mounting frame 2 are arranged on the vehicle roof in parallel and spaced apart, and the screen 11 is arranged between the two, so that the subsequent screen 11 slides between the first mounting frame 1 and the second mounting frame 2. The first mounting frame 1 and the second mounting frame 2 can be connected to the vehicle roof by bolts 10. The first driving device 3 is used to provide power for the flipping of the screen 11, and the translation mechanism is used to provide power for the forward and backward movement of the screen 11. The first guide rail 8 and the first driving device 3 are both arranged on the first mounting frame 1. The first driving device 3 and the first guide rail 8 are slidably matched, so that when the translation mechanism acts on the front and back of the screen 11, the first driving device 3 can also move synchronously on the first guide rail 8, so that the screen 11 can move between the first mounting frame 1 and the second mounting frame 2 in a stable and balanced manner. The mounting plates that can extend downward at both ends of the first mounting frame 1 are convenient for installing the first guide rail 8, and the mounting plates that extend downward at both ends of the second mounting frame 2 are convenient for installing the second driving device, such as installing the second driving device on the outside of the corresponding mounting plate; the groove area in the first mounting frame 1 and the second mounting frame 2 can also play a role in limiting the forward and backward movement of the screen 11. By providing the first driving device 3 and the translation mechanism, the two rows of screens in the rear row can be flipped or slid respectively, which can avoid the inconvenience caused by the rearward movement of the front seats, and can also meet the needs of adjusting a larger screen to avoid the front seats. The simple structure can realize the adjustment of the screen angle and distance, meeting the more complex adjustment needs of passengers.
[0034] According to some embodiments of the present application, reference Figure 1 and Figure 2 As shown, a plurality of first guide rails 8 are arranged in parallel and spaced apart on the first mounting frame 1, and the first driving device 3 is sleeved on the plurality of first guide rails 8. The number of the first guide rails 8 can be two, three or more. The first driving device 3 is provided with corresponding perforations, and the guide rails and the perforations are slidably matched. One or more second guide rails 12 are arranged on the second mounting frame 2, and the second guide rails 12 are parallel to the first guide rails 8. The transmission unit 5 is sleeved on the second guide rails 12. The number of the second guide rails 12 can be one, two or more. The second guide rails 12 are provided with corresponding perforations, and the guide rails and the perforations are slidably matched.
[0035] Specifically, the first driving device 3 can slide on the plurality of first guide rails 8 , and the transmission unit 5 can slide on the second guide rail 12 .
[0036] The first drive device 3 is sleeved on a plurality of first guide rails 8, and there are intervals between the plurality of first guide rails 8, so as to avoid the phenomenon that the first drive device 3 is twisted when it is sleeved on only one first guide rail 8, which causes the first drive device 3 to be installed unstably. Similarly, one or more second guide rails 12 are provided on the second mounting frame 2, so as to ensure the stability of the installation of the transmission unit 5.
[0037] According to some embodiments of the present application, reference Figure 1 and Figure 2 As shown, the vehicle-mounted slide rail screen includes a first movable slider 6 and a first connecting rod 9, wherein the first movable slider 6 is sleeved on the first guide rail 8, the first end of the first connecting rod 9 is rotatably connected to the first movable slider 6, and the second end of the first connecting rod 9 is rotatably connected to one of the side edges of the screen 11. The vehicle-mounted slide rail screen also includes a second movable slider 13 and a second connecting rod 14, the second movable slider 13 is sleeved on the second guide rail 12, the first end of the second connecting rod 14 is rotatably connected to the second movable slider 13, and the second end of the second connecting rod 14 is rotatably connected to the other side edge of the screen 11.
[0038] Specifically, the first movable slider 6 and the second movable slider 13 are symmetrically arranged on the first guide rail 8 and the second guide rail 12 on both sides of the screen 11, and the corresponding first connecting rod 9 and the second connecting rod 14 also need to be symmetrically arranged.
[0039] The first movable slider 6 and the second movable slider 13 are respectively mounted on the first guide rail 8 and the second guide rail 12, so that when the screen 11 moves, the first movable slider 6 and the second movable slider 13 can also be displaced synchronously. The first end of the first connecting rod 9 is rotatably connected to the first movable slider 6, and the second end of the first connecting rod 9 is rotatably connected to one of the sides of the screen 11. When the first driving device 3 can provide power for the flipping of the screen 11, the first end of the first connecting rod 9 is rotatably connected to the first movable slider 6, and because the second end of the first connecting rod 9 rotates relative to one of the sides of the screen 11, when the screen 11 flips, the first connecting rod 9 can rotate between the first movable slider 6 and the screen 11 to assist in adjusting the flipping angle of the screen 11. Similarly, the first end of the second connecting rod 14 is rotatably connected to the second movable slider 13, and the second end of the second connecting rod 14 is rotatably connected to the other side of the screen 11, and the second connecting rod 14 can rotate between the second movable slider 13 and the screen 11. The arrangement of the first movable slider 6, the second movable slider 13, the first connecting rod 9 and the second connecting rod 14 assists the hanging of the screen 11, thereby enhancing the stability of the rear screen when in use and is suitable for a large-sized vehicle-mounted screen or a heavy vehicle-mounted screen.
[0040] According to some embodiments of the present application, reference Figure 1 The second end of the first connecting rod 9 is connected to the screen 11 between the middle position of the corresponding side and the top of the screen 11; the second end of the second connecting rod 14 is connected to the screen 11 between the middle position of the corresponding side and the top of the screen 11.
[0041] By connecting the second end of the first connecting rod 9 to the screen 11 between the middle position of the corresponding side and the top of the screen 11; connecting the second end of the second connecting rod 14 to the screen 11 between the middle position of the corresponding side and the top of the screen 11, the setting of the first connecting rod 9 and the second connecting rod 14 can sink the hinge point of the flipping of the screen 11, increase the force arm of the screen 11 when flipping, and reduce the performance requirements on the first drive device 3. At the same time, the larger force arm can enable the first drive device 3 to provide less force when working, thereby reducing the wear on the drive shaft of the first drive device 3 and the screen 11.
[0042] According to some embodiments of the present application, reference Figures 1 to 5 The second driving device includes a first motor 4 and a screw rod 7. The first motor 4 is arranged on the second mounting frame 2. The screw rod 7 extends along the first direction and is driven to rotate by the first motor 4. The transmission unit 5 is threadedly connected to the screw rod 7.
[0043] Specifically, the first motor 4 can provide power for the screw rod 7 to drive the screw rod 7 to rotate. The transmission unit 5 is provided with threads matching the surface texture of the transmission unit 5. When the first motor 4 drives the screw rod 7 to rotate, the transmission unit 5 can move in the extension direction of the screw rod 7.
[0044] The transmission unit 5 is threadedly connected to the screw rod 7, so that the clockwise or counterclockwise rotation of the screw rod 7 can be converted into the forward and backward movement of the transmission unit 5 in the extension direction of the screw rod 7. By controlling the power of the first motor 4, the movement speed of the transmission unit 5 can be selected, so as to facilitate the precise adjustment of the position of the screen 11.
[0045] Of course, in other embodiments, the second driving device includes a second motor, a transmission belt, a driving wheel and a driven wheel. The second motor is mounted on the second mounting frame 2, the driving wheel is mounted on the output shaft of the second motor, the driven wheel is mounted on the second mounting frame 2 and is spaced apart from the driving wheel in the first direction, the transmission belt is sleeved on the driving wheel and the driven wheel, and the transmission unit is connected to a circumferential position of the transmission belt.
[0046] Specifically, the second motor provides the driving wheel with a rotational force, and the driving wheel drives the driven wheel and the conveyor belt to rotate. Because the driven wheel is mounted on the second mounting frame 2 and is spaced apart from the driving wheel in the first direction, there is a certain distance between the driven wheel and the driving wheel. Because the second driving device is in transmission connection with the transmission unit 5, the transmission unit 5 can move within the distance range between the driven wheel and the driving wheel as the crawler belt rotates.
[0047] By connecting the transmission unit 5, the second motor, the transmission belt, the driving wheel and the driven wheel, the clockwise or counterclockwise rotation of the driving wheel can be converted into the forward and backward movement of the transmission unit 5 in the extension direction of the transmission belt. By controlling the power of the second motor, the moving speed of the transmission unit 5 can be selected, so as to facilitate the precise adjustment of the position of the screen 11.
[0048] At the same time, in other embodiments, the second driving device includes a third motor, a gear and a rack. The third motor is mounted on the second mounting frame 2, the gear is mounted on the output shaft of the third motor, the gear is slidably connected to the second mounting frame 2 in the first direction, the gear is meshed with the rack, and the transmission unit 5 is arranged on the rack.
[0049] Specifically, the third motor is installed on the second mounting frame 2, and the third motor drives the gear to rotate. The gear is meshed with the rack, and the rack can move in the first direction relative to the gear. Because the transmission unit 5 is arranged on the rack, when the rack moves, the transmission unit 5 also moves in the first direction accordingly.
[0050] Through the coordinated connection of the transmission unit 5, the third motor, the gear and the rack, the clockwise or counterclockwise rotation of the gear can be converted into the forward and backward movement of the transmission unit 5 in the extension direction of the rack. By controlling the power of the third motor, the movement speed of the transmission unit 5 can be selected, so as to facilitate the precise adjustment of the position of the screen 11.
[0051] It is worth noting that the second driving device can also directly use a device with a telescopic function, such as a telescopic cylinder, and rotatably connect one side of the screen 11 to the telescopic cylinder, which can also achieve the screen 11 being able to move along the first direction of the second mounting frame 2.
[0052] refer to Figure 1 and Figure 2 As shown, in some embodiments, the first drive device 3 is a one-way locking device. Of course, in other embodiments, the first motor 4, the second motor and the third motor may also be one-way locking devices.
[0053] Specifically, the "one-way locking" here means that the first drive device 3, the first motor 4, the second motor and the third motor can actively provide a locking function. If subjected to external force, such as the screen being subjected to a reverse external force, the first drive device 3, the first motor 4, the second motor and the third motor will still remain in a locked state.
[0054] If the screen 11 rotates due to external force, the one-way locking device will cut off the power, thereby realizing the function of the screen 11 hovering at any position within the motion trajectory. The encoder set in the one-way locking module is used to identify the angular position of the screen 11 within the motion trajectory, thereby realizing accurate hovering action.
[0055] Some embodiments of the present disclosure also provide a vehicle, including a vehicle-mounted sliding screen as described in any of the above items. When the vehicle in the present application is in use, the above-mentioned vehicle-mounted sliding screen is installed, so that passengers can avoid the inconvenience caused by the rearward movement of the front seats when in use, and can also adapt to the need for larger screens to avoid the adjustment of the front seats. At the same time, the vehicle-mounted screen is installed on the roof of the vehicle, and the vehicle-mounted screen can be stored on the roof after use, saving the use space in the vehicle.
[0056] The content of this application is not limited to the examples listed in the embodiments, and any equivalent changes made to the technical solution of this application by ordinary technicians in this field after reading the description of this application are covered by the claims of this application.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
