Electric lift armrest structure

Abstract

The invention relates to an electric lifting armrest structure, belonging to an armrest structure. The electric lifting armrest structure comprises a fixing framework, an armrest framework, first connecting rods, second connecting rods, third connecting rods, fourth connecting rods and an electric push rod, wherein the first connecting rods are hinged to the armrest framework, the first connecting rods are hinged to the fixing framework, the second connecting rods are hinged to the armrest framework, the second connecting rods are hinged to the fixing framework, the third connecting rods are hinged to the second connecting rods, the third connecting rods are hinged to the fourth connecting rods, the fourth connecting rods are hinged to the fixing framework, the push rod end of the electric push rod is simultaneously hinged to the third connecting rods and the fourth connecting rods, the tail end of the electric push rod is hinged to the lower part of the fixing framework, the fixing framework, the armrest framework, the first connecting rods and the second connecting rods form a parallelogram-shaped connecting rod mechanism, and the second connecting rods, the third connecting rods, the fourth connecting rods and the fixing framework form a trapezium-shaped connecting rod mechanism. The electric lifting armrest structure has the advantages of simple design, operation convenience, strong adjustability and good stability.

Description

Technical field: [0001] The invention relates to a handrail structure, in particular to an electric lifting handrail structure. Background technique: [0002] Wheelchairs or nursing beds are products for the elderly or patients. These products need to be equipped with corresponding armrest structures or guardrail structures to protect the safety of users and provide users with support. In the early days, the armrest or guardrail was set fixed, which would hinder the user's movement when the user went up and down the product. Subsequently, liftable armrests appeared. The existing design is mainly implemented manually, which is not convenient for the elderly or patients to operate in person. At the same time, the design posture is less, and only the highest point and the lowest point can maintain a stable structure. , unable to adapt to the different needs of users. With the development of science and technology, adopting an electric method to control the lifting of the hand...

Problems solved by technology

Subsequently, liftable armrests appeared. The existing design is mainly implemented manually, which is not convenient for the elderly or patients to operate in person. At the same time, the design posture is less, and only the highest point and the lowest point can maintain a stable structure. , unable to adapt to the different needs of users

With the development of science and technology, the use of electric methods to control the lifting of the handrail can better meet the needs of customers, but there are problems in the existing technology with complex structure and poor stability
