Description

Technical Field

[0001] This utility model belongs to the field of vehicle ceiling screen technology, specifically, it relates to a vehicle ceiling screen flipping mechanism. Background Technology

[0002] With continuous social progress and a significant improvement in people's quality of life, cars have long become an indispensable means of transportation for daily travel. In order to more accurately meet the diverse needs of users, electronic ceiling screens that combine entertainment, learning, and work functions are often installed in the interior of cars.

[0003] To save interior space and protect the screen, most of these ceiling-mounted screens adopt a hidden design. This is achieved by incorporating a flip or folding structure on the screen to conceal it. Users can unfold the screen according to their needs.

[0004] In terms of the application of the flip structure, the flipping method of the ceiling-mounted screen is mainly divided into two types: manual operation and electric operation. In manual operation mode, the user needs to manually open or close the vehicle ceiling-mounted screen; electric operation mode uses a motor to drive the ceiling-mounted screen to complete the opening or closing action, and the user only needs to issue the corresponding command to the motor to easily achieve the operation.

[0005] However, at present, when using an electric motor to open or close the in-vehicle ceiling screen, the motor drive is prone to vibration, which in turn generates noise. This noise can interfere with human hearing and ultimately affect the user experience. Utility Model Content

[0006] In order to solve the problems existing in the prior art, this utility model aims to provide a vehicle-mounted ceiling screen flipping mechanism, so as to achieve smooth and low-noise driving of the ceiling screen to flip while improving the flipping torque.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A vehicle-mounted ceiling-mounted screen flipping mechanism includes a housing, a drive module, a linkage module, and a multi-stage gear module. The drive module is mounted on the housing. A portion of the linkage module passes through the housing via a bushing. The multi-stage gear module is disposed within the internal space of the housing. The drive module is connected to the linkage module via the multi-stage gear module, and the drive module can drive the linkage module to rotate within the housing via the multi-stage gear module.

[0009] Furthermore, the housing is provided with fixed feet around its perimeter, and shock-absorbing pads are provided inside the fixed feet.

[0010] Furthermore, the drive module is a drive motor.

[0011] Furthermore, the linkage module includes a connecting rod and a damping spring, with the damping spring disposed on the connecting rod.

[0012] Furthermore, the connecting rod has a connecting hole.

[0013] Furthermore, the multi-stage gear module includes a first-stage driving worm gear, a first gear section, a second gear section, a third gear section, a fourth gear section, and an actuating gear that are sequentially meshed together; a five-stage gear module is formed by the first-stage driving worm gear, the first gear section, the second gear section, the third gear section, the fourth gear section, and the actuating gear.

[0014] Furthermore, the first gear section, the second gear section, the third gear section, and the fourth gear section all employ double gears.

[0015] Furthermore, the actuating gear is a sector gear.

[0016] The beneficial effects of this utility model are as follows: This utility model uses a multi-stage gear module for transmission between the drive motor and the connecting rod, and a damping spring is set in the connecting rod, which effectively avoids vibration and noise caused by the motor drive during the opening or closing of the electric-driven vehicle ceiling screen, thus improving the comfort and experience of use; secondly, the multi-stage gear module adopts a five-stage reduction gear module, which effectively improves the flipping torque while achieving compact assembly between the gears, effectively reducing the size of the device.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] See Figure 1-2 As shown, a vehicle-mounted ceiling-mounted screen flipping mechanism includes a housing 1, a drive module 2, a connecting rod module 3, and a multi-stage gear module 4. The drive module 2 is mounted on the housing 1. The connecting rod module 3 partially passes through a bushing 5 inside the housing 1. The multi-stage gear module 4 is disposed within the internal space of the housing 1. The drive module 2 is connected to the connecting rod module 3 via the multi-stage gear module 4, and the drive module 2 can drive the connecting rod module 3 to rotate within the housing 1 via the multi-stage gear module 4. In this example, the drive module 2 is a drive motor.

[0029] Further, see Figure 1As shown, the housing 1 consists of a main housing and multiple sets of sub-housings. The main housing and the sub-housings are detachably connected by locking screws, which facilitates the assembly of the internal components of the housing 1. The main housing has fixing feet 11 around its perimeter, and shock-absorbing pads 6 are provided inside the fixing feet 11. During installation, the locking screws pass through the shock-absorbing pads 6 to fix the housing 1. At this time, the shock-absorbing pads 6 can effectively prevent the mechanism from vibrating during operation. In this embodiment, the shock-absorbing pads 6 are made of rubber.

[0030] Further, see Figure 3-4 As shown, the linkage module 3 includes a connecting rod 31 and a damping spring 32. During installation, the rear end of the connecting rod 31 is rotatably inserted into the housing 1 through a pair of bushings 5. The damping spring 32 is disposed on the connecting rod 31 and located between the pair of bushings 5. The damping spring 32 plays a buffering and shock-absorbing role when the connecting rod 31 rotates, ensuring the smoothness and reliability of the operation of the linkage module 3. A connecting hole 311 is provided at the front end of the connecting rod 31. The connecting rod 31 is fixed to the ceiling screen through the connecting hole 311. In this embodiment, three sets are provided, but not limited to three sets. The specific setting can be set according to the requirements.

[0031] Further, see Figure 3 As shown, the multi-stage gear module 4 includes a first-stage driving worm gear 41, a first gear section 42, a second gear section 43, a third gear section 44, a fourth gear section 45, and an actuating gear 46 that are sequentially meshed together; a five-stage gear module is formed by the first-stage driving worm gear 41, the first gear section 42, the second gear section 43, the third gear section 44, the fourth gear section 45, and the actuating gear 46.

[0032] Among them, see Figure 4 As shown, the first gear section 42 includes a first-stage driven gear 421 and a second-stage driving gear 422; the second gear section 43 includes a second-stage driven gear 431 and a third-stage driving worm gear 432; the third gear section 44 includes a third-stage driven gear 441 and a fourth-stage driving gear 442; and the fourth gear section 45 includes a fourth-stage driven gear 451 and a fifth-stage driving gear 452. Therefore, in this embodiment, the first gear section 42, the second gear section 43, the third gear section 44, the fourth gear section 45, and the fifth gear section 46 all adopt double gears; and the actuating gear 46 is a sector gear.

[0033] During installation, the first-stage driving worm gear 41 is sleeved on the output shaft of the drive motor; the first gear section 42, the second gear section 43, the third gear section 44, and the fourth gear section 45 are all rotatably mounted in the housing 1 via corresponding pins; and the actuating gear 46 is sleeved on the connecting rod 31 and can drive the connecting rod 31 to rotate synchronously with it; at this time, the first-stage driving worm gear 41 and the first-stage driven gear 421, as well as the third-stage driving worm gear 432 and the third-stage driven gear 441, form a worm gear transmission, while the second-stage driving gear 422 and the second-stage driven gear 431, the fourth-stage driving gear 442 and the fourth-stage driven gear 451, and the fifth-stage driving gear 452 and the actuating gear 46 are all meshed and connected.

[0034] The working principle of this utility model is as follows:

[0035] Before use, please refer to Figure 5-6 As shown (label A in the figure represents the ceiling screen mechanism, and label B in the figure represents this mechanism), firstly, this mechanism is connected to the ceiling screen through the connecting rod module 3, and then this mechanism is fixed in the ceiling screen machine.

[0036] When the ceiling-mounted screen needs to be opened, the drive motor is activated. The drive motor drives the primary worm gear 41 to rotate, and after transmission through the first gear section 42, the second gear section 43, the third gear section 44, and the fourth gear section 45, it drives the actuating gear 46 to rotate. The rotating actuating gear 46 drives the connecting rod 31 to rotate synchronously, thereby opening the ceiling-mounted screen. After the ceiling-mounted screen is opened to the required angle, the drive motor is turned off. It should be noted that because the actuating gear 4 is fan-shaped, it controls the rotation angle of the connecting rod 31, thereby controlling the maximum rotation angle of the ceiling-mounted screen.

[0037] When the ceiling screen needs to be closed, start the drive motor and control it to rotate in the opposite direction. The control principle is the same as when it is open, so it will not be described in detail here. When the ceiling screen is closed to the required angle or completely closed, turn off the drive motor.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
