Description

Technical Field

[0001] The utility model relates to the technical field of vehicle armrests, in particular to a vehicle armrest with an electric lifting function. Background Art

[0002] Vehicle armrests are facilities that provide support and balance to passengers while driving. They are usually located on the top or side of the car, and passengers can hold the armrests to maintain a standing position. The design of armrests can take many forms, such as horizontal bars fixed to the roof, longitudinal armrests along both sides of the seat, etc. These armrests are designed based on passenger needs and safety considerations to ensure that passengers can stand firmly and comfortably while the car is moving.

[0003] The handrails traditionally fixed on the roof crossbars are often set at different heights to meet the needs of different users, so users are required to stand under handrails at different heights. However, when there are many passengers in the car, it is difficult for users with different needs to choose the handrails they need. At the same time, the handrails with different height settings cannot be adjusted, making it difficult to meet users' needs for handrails of different heights.

[0004] Based on this, a vehicle armrest with electric lifting function is designed. Utility Model Content

[0005] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

[0006] A vehicle armrest with an electric lifting function comprises a handle and a metal buckle arranged directly above the handle, a woven belt is fixed to the upper part of the metal buckle, an electric lifting mechanism is arranged between the handle and the metal buckle, a descending switch and an ascending switch for controlling the raising and lowering of the electric lifting mechanism are installed on the side surface of the handle, and a rubber sleeve for preventing hand gripping from slipping is sleeved on the lower part of the handle.

[0007] As an improvement of the above technical solution, the electric lifting mechanism includes an electric motor fixed on the upper part of the handle, and a reduction gearbox installed on the upper end of the motor, and the output shaft of the motor is connected to the input shaft of the reduction gearbox, and the output shaft at the upper end of the reduction gearbox is fixed with a screw, and an internally threaded sleeve is screwed on the outside of the screw, and the internally threaded sleeve is welded and fixed to a metal buckle, and a limiting mechanism is also arranged between the metal buckle and the reduction gearbox.

[0008] As an improvement of the above technical solution, the limiting mechanism includes a sleeve welded on the surface of the metal buckle and a limiting rod welded on the upper end of the reduction box, and the upper end of the limiting rod is movably installed inside the sleeve.

[0009] As an improvement of the above technical solution, a first limiting ring is welded on the inner surface of the lower end of the sleeve, and a second limiting ring is welded on the outer surface of the upper end of the limiting rod. The sleeve and the limiting rod are limited by the first limiting ring and the second limiting ring.

[0010] As an improvement of the above technical solution, annular grooves distributed at equal intervals are provided on the outer surface of the rubber sleeve.

[0011] As an improvement of the above technical solution, a bellows is further provided between the reduction box and the metal buckle.

[0012] Beneficial effects of the utility model:

[0013] 1. An electric lifting mechanism is set between the handle and the metal buckle, and the descending switch and ascending switch installed on the handle side are used to control the lifting of the electric nerve mechanism, thereby solving the needs of different users for installing the handle at different heights, thereby increasing the comfort of users using the armrest, and the rubber sleeve sleeved on the lower part of the handle makes the lower part of the handle more anti-slip for users to hold.

[0014] 2. An electric lifting mechanism composed of a motor, a reduction gearbox, a screw, an internal threaded sleeve and a limiting mechanism is used. The output speed of the motor is reduced by the reduction gearbox, so that the output shaft at the upper end of the reduction gearbox can rotate with the screw in the internal threaded sleeve. The limiting mechanism is set between the metal buckle and the reduction gearbox to prevent the internal threaded sleeve from rotating with the metal buckle when the screw rotates inside the internal threaded sleeve. This makes it easier for the screw to rotate in the internal threaded sleeve. The length of the screw and the internal threaded sleeve can be adjusted, thereby realizing the lifting and lowering of the handrail.

[0015] 3. Through the limiting mechanism composed of a sleeve and a limiting rod, the limiting rod welded on the upper end of the reduction box is movably installed in the sleeve welded on the surface of the metal buckle, so that the sleeve and the limiting rod cooperate to limit the reduction box and the metal buckle, and the first limiting ring welded on the inner surface of the lower end of the sleeve and the second limiting ring welded on the outer surface of the upper end of the limiting rod cooperate to prevent the limiting rod from detaching from the inside of the sleeve.
