Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a novel electric liftable seat armrest. Background Technology

[0002] Existing car seat side armrests include manually foldable armrests, electrically foldable armrests, and fixed airline-style armrests. Foldable armrests are traditional, requiring manual folding due to their core locking mechanism. Electrically foldable armrests fold electrically to the side of the seat, placing both armrests on the inside of the seat and obstructing aisle space. Fixed airline-style armrests are fixed and cannot be folded away to avoid obstruction. When passengers require more legroom or greater ergonomic space without armrest obstruction, foldable armrests are cumbersome and unsuitable for elderly passengers, while fixed airline-style armrests are completely unsuitable due to their lack of adjustability. Therefore, a new type of armrest structure is urgently needed. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a new type of electric lifting seat armrest. The armrest can be electrically raised and lowered to save space in the vehicle, and it provides a welcoming mode for the seat to facilitate passengers getting on and off the vehicle. After the passengers are seated, the armrest can be electrically raised for their use, which greatly improves the comfort of the seat.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel electric height-adjustable seat armrest includes an armrest cover, an armrest frame, an inner armrest panel, an armrest connecting plate, an inner slide rail, an outer slide rail, a side support plate, a motor assembly, and a motor mounting bracket. The armrest cover and armrest frame are assembled together to form a top cover sub-assembly, which is snapped onto the inner armrest panel. The inner armrest panel and a T-shaped armrest connecting plate are assembled together. The upper and lower telescopic portions of the armrest connecting plate have inner slide rails installed near both sides. The inner slide rails are slidably connected to the outer slide rails. The outer slide rails are installed on both sides of the side support plate, which is fixed to the seat frame. The motor assembly is mounted and fixed to the side support plate, and the end of the lifting screw on the motor assembly is fixed to the lower end of the armrest connecting plate.

[0006] As a preferred embodiment of this utility model, the novel electric lifting seat armrest further includes a T-shaped support arm guard plate. The support arm guard plate includes a vertical cavity and a horizontal assembly groove. A T-shaped armrest connecting plate with an inner rail of the slide rail is installed inside the support arm guard plate. The upper and lower telescopic parts of the armrest connecting plate are located in the vertical cavity, and the horizontal assembly part of the armrest connecting plate is located in the horizontal assembly groove. The support arm guard plate has an avoidance notch at a position opposite to the outer rail of the slide rail. The support arm guard plate and the armrest connecting plate move up and down synchronously.

[0007] As a preferred embodiment of this utility model, the novel electric lifting seat armrest further includes an outer guard plate and an inner guard plate. The outer guard plate and the inner guard plate are respectively disposed on the outer side and the inner side of the side support plate. The outer guard plate and the inner guard plate are assembled together by a snap-fit ​​method. The inner guard plate is provided with an avoidance groove at the position opposite to the support arm guard plate.

[0008] As a preferred embodiment of this utility model, the novel electric lifting seat armrest further includes armrest foam, which is assembled onto the armrest frame through a foaming process. The armrest cover is used to cover the armrest foam to form an upper cover sub-assembly, which is snapped onto the inner panel of the armrest by a snap-fit ​​method.

[0009] As a preferred embodiment of this utility model, the motor assembly is mounted and fixed on the side support plate by a motor mounting bracket.

[0010] Advantages and beneficial effects of this utility model:

[0011] (1) This utility model adopts an innovative form of slide rail, metal bracket, motor and push rod to change the handrail into an electric up and down lifting motion mechanism, innovate the motion form and spatial layout of the handrail, and provide a more comfortable welcoming mode.

[0012] (2) The space-saving electric up-and-down retractable armrest provided by this utility model saves space in the vehicle by lowering and retracting the armrest, provides a welcoming mode for the seat, facilitates passengers getting on and off the vehicle, and then raises the armrest electrically for passengers to use after they are seated, which greatly improves the comfort of the seat.
