[0002] At present, the PADs provided on general rear seat armrests are basically horizontally fixed on the rear seat armrests with the display surface facing up. In this way, if a passenger on the seat wants to view the picture on the PAD display surface or operate the operation buttons on the PAD display surface, they need to look down, which brings inconvenience to the passengers. Especially for long-term viewing, it will more harm the neck health of the passengers. Summary of the Invention

[0003] The purpose of the utility model is to provide a PAD bracket mechanism for a rear seat armrest, in which the position and angle of the PAD display surface on the rear seat armrest can be adjusted, the size of the PAD can be replaced, the viewing and adjustment angles of the PAD by passengers are comfortable.

[0004] The purpose of the utility model is solved as follows:

[0005] A PAD bracket mechanism for a rear seat armrest includes a lower slide rail provided on the rear seat armrest, an upper slide rail slidably arranged on the lower slide rail, a slide plate installed on the upper slide rail, a PAD bracket hinged to the rear of the slide plate, and a PAD clamped on the PAD bracket. When the slide plate slides into a contracted state, a locking device for locking the slide plate in an initial state is provided on the armrest, and the locking device is unlocked by a button provided on the armrest.

[0006] Since the PAD is installed on the armrest through the PAD bracket upper and lower slide rail mechanism, the position and angle of the PAD display surface can be adjusted, the size of the PAD can be replaced, and the viewing and adjustment angles of the PAD by passengers are comfortable.

[0007] As a further optimization of the above technical solution, the locking device includes a "convex"-shaped groove provided on the slide plate, a "convex"-shaped lock block clamped in the "convex"-shaped groove, and a first return spring is arranged between the "convex"-shaped lock block and the bottom of the "convex"-shaped groove; when the slide plate slides into a contracted state, the rear part of the rear seat armrest is higher than the front part to form a high platform at the rear part, and an automatically liftable button is arranged in a through hole corresponding to the "convex"-shaped groove on the high platform. Pressing the button can make the "convex"-shaped lock block extend into the "convex"-shaped groove.

[0008] As a further optimization of the above technical solution, the specific structure of the button that can be automatically lifted is as follows: a diameter-expanded portion is provided in the middle of the through hole of the high platform to form a "middle" - shaped hole, the button is arranged in the "middle" - shaped hole and its axial protruding height is limited by the diameter-expanded portion, and a second return spring is arranged between the lower part of the button and the diameter-expanded portion.

[0009] Of course, the above locking device can also be realized by a structure in which an elastic convex block cooperates with a groove for locking, and pressing the convex block can unlock it.

[0010] As a further optimization of the above technical solution, the rear part of the rear seat armrest is higher than the front part to form a high platform at the rear part. A groove extending backward is provided on the front end face of the high platform. The rear part of the sliding plate slides into the groove, and a third spring capable of ejecting the sliding plate is arranged between the rear part of the sliding plate and the bottom of the groove; setting the high platform is beneficial to protecting the PAD bracket and the PAD clamped on the PAD bracket.

[0011] As a further optimization of the above technical solution, a convex platform extending upward is provided at the front part of the sliding plate, and the height of the convex platform is higher than or equal to the upper surface of the PAD when the PAD is placed flat on the upper surface of the sliding plate.

[0012] As a further optimization of the above technical solution, the lower slide rail is a "T" - shaped strip or an inverted trapezoidal groove provided on the main body.

[0013] As a further optimization of the above technical solution, the upper slide rail is a slider that can be axially slid on the "T" - shaped strip or the inverted trapezoidal groove.

[0014] The above - mentioned upper and lower slide rails can also be realized by a mortise - and - tenon structure.

[0015] The utility model belongs to the PAD functional mechanism on the armrest. Compared with other similar products on the current market, on the premise of meeting the armrest strength requirements, the structural principle is relatively simple, the manufacturing difficulty will be significantly improved, the manufacturing cost can be effectively reduced, it is quick and convenient to use, highly personalized, and has high safety.

[0016] The utility model discloses a PAD bracket for supporting the inclined movement of a screen on the middle armrest of a rear seat. The PAD bracket mechanism includes an armrest sliding assembly, a PAD bracket, a PAD bracket rotating shaft, and a trigger button. By applying an unlocking force to the trigger button, the unlocking sliding assembly slides outward, and then a force is applied to lift the PAD bracket and adjust it to a suitable angle and position around the PAD bracket rotating shaft. The PAD can be detached and replaced separately, and has strong practicability. The trigger - type button has a small unlocking force, is convenient to unlock, ensures the convenience of use; at the same time, it restricts the PAD from being thrown out randomly, ensuring the safety of the occupants.
