Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted display screens, and particularly relates to a translation and flipping mechanism for a vehicle-mounted display screen. Background Art

[0002] In order to improve the riding experience of rear passengers in a vehicle, a display screen is generally installed at the rear of the vehicle seat to facilitate the operation of movies, music, and games by the passengers. However, the position of such a vehicle-mounted display screen will change with the adjustment of the front seat, affecting the viewing experience of the rear passengers. Therefore, the ceiling-mounted display screen has gradually become the mainstream. By installing it on the top of the vehicle, the viewing experience of the rear passengers will not be affected when the front seat is adjusted.

[0003] The existing ceiling-mounted display screen is unfolded by two driving methods, manual and electric. However, the mechanism for realizing the flipping and translation of the display screen will occupy a large space, and even be exposed when the display screen is in the open state, resulting in an unattractive appearance and affecting the comfort of the passengers. Secondly, the vehicle will continuously shake during driving, which is also likely to cause the display screen to accidentally open during the shaking.

[0004] Therefore, we provide a translation and flipping mechanism for a vehicle-mounted display screen to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a translation and flipping mechanism for a vehicle-mounted display screen. Through the cooperative setting of a translation and flipping component and a locking component, the problems in the prior art that the translation and flipping mechanism of the vehicle-mounted display screen will occupy a large space, affect the aesthetics and the comfort of the passengers, and is likely to accidentally open during the shaking of driving are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a translation and flipping mechanism for a vehicle-mounted display screen, including a housing, a translation and flipping component, and a locking component. An installation plate is arranged at the top of the housing, and an electric push rod is fixedly connected to the bottom of the installation plate. The front side of the output end of the electric push rod is fixedly connected to the housing;

[0008] The translation and flipping component is arranged in the inner cavity of the housing and includes a first motor. The left side of the output end of the first motor is fixedly connected to a rotating shaft. The rear side of the rotating shaft is fixedly connected to a control box. A second motor is fixedly connected to the left side of the inner cavity of the control box. The right side of the output end of the second motor is fixedly connected to a screw rod. A threaded sleeve is threadedly connected to the surface of the screw rod. The rear side of the threaded sleeve penetrates through the control box and is fixedly connected to a display screen body;

[0009] The locking components are arranged on both sides of the top of the housing and include a locking box. A third motor is fixedly connected to the bottom of the inner cavity of the locking box. The top of the output end of the third motor is fixedly connected with a cam. A hook is arranged behind the cam. The rear side of the hook penetrates to the outside of the locking box. Magnets are fixedly connected to the top of the rear side of the hook and the rear side of the inner cavity of the locking box respectively.

[0010] The present utility model is further configured such that the left side of the rotating shaft is movably connected to the inner wall of the housing through a bearing, and an activity opening for cooperating with the threaded sleeve is provided at the rear side of the control box.

[0011] The present utility model is further configured such that sliding rods are fixedly connected to both sides of the top of the housing. The surface of the sliding rods is slidably connected with sliding sleeves. One side of the two sliding sleeves facing each other is fixedly connected to the mounting plate.

[0012] The present utility model is further configured such that mounting holes are provided at the top of the mounting plate. The number of the mounting holes is four, and they are evenly distributed at the top of the mounting plate.

[0013] The present utility model is further configured such that a buffer strip is fixedly connected to the rear side of the top of the inner cavity of the housing, and a dismounting and assembling plate is fixedly connected to the bottom of the control box through bolts.

[0014] The present utility model is further configured such that connecting plates are fixedly connected to the bottom of the front side and the rear side of the locking box, and fixing holes are provided at the top of the connecting plates.

[0015] The present utility model is further configured such that the shape of the hook is U-shaped, and the magnetic poles of the opposite sides of the two magnets are the same.

[0016] The present utility model is further configured such that an activity opening for cooperating with the hook is provided at the rear side of the locking box, and the top of the cam is movably connected to the inner wall of the locking box.

[0017] The present utility model has the following beneficial effects:

[0018] 1. Through the setting of the translation and flipping assembly, the present utility model can install the housing between the vehicle frame and the roof interior trim panel through the mounting plate. A square opening is provided at the bottom of the interior trim panel between the front row seats and the rear row seats. The square opening is blocked by a hinge and a square baffle. When the electric push rod is turned on, the electric push rod drives the housing to move, and the rear side of the display body is moved directly above the square opening. Then, the electric push rod is slowly reset and the first motor is turned on. The first motor drives the display body to rotate around the rotating shaft through the rotating shaft and the control box, so that the display body passes through the square opening and enters the vehicle interior. When moving horizontally, the second motor is turned on. The second motor cooperates with the screw rod to drive the threaded sleeve and the display body to move horizontally, improving the comfort of the rear row passengers.

[0019] 2. With the locking component provided in the present utility model, when the display screen body is retracted into the inner cavity of the housing, the third motor is turned on. The third motor drives the cam to rotate, so that the cam no longer presses the hook. At this time, the two magnets repel each other, causing the hook to move forward. The movement of the hook locks and fixes the rear side of the display screen body, preventing the display screen body from being accidentally unfolded during vehicle driving and causing damage to it, and improving the service life of the display screen body.

[0020] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
