Reinforced horizontal adjusting device and automobile electric seat comprising same

Abstract

The invention discloses a reinforced horizontal adjusting device and an automobile electric seat comprising the reinforced horizontal adjusting device. The reinforced horizontal adjusting device comprises a first external box body and a second external box body which are arranged outside, the first external box body is provided with a threaded hole, a through hole is formed in the corresponding position of the second box body, and the position, where the threaded hole is located, of the first external box body is provided with a thickening part protruding outwards; and the position of the through hole of the second external box body is provided with a thinning part which is sunken inwards. Under the condition that the overall structure size is not increased, a purpose of improving the tensile strength of the first outer box body and the second outer box body is achieved, and use safety and reliability of the automobile electric seat sliding rail are improved; and heat dissipation openings are added, so the heat dissipation performance is improved. An over-positioning structure is achieved, so the tolerance compensation effect is achieved, and the probability of assembly difficulty caused by machining errors is reduced.

Description

technical field [0001] The invention relates to a reinforced horizontal adjustment device and an electric car seat including the same. Background technique [0002] At present, when the electric seat of an automobile is subjected to a collision, it is very easy to cause damage and failure of the slide rail assembly, causing the seat to slip off and affecting the personal safety of the driver. The seat level adjustment device is a transmission device that connects the upper and lower rails of the seat. Its stability and tensile strength will directly affect the safety and reliability of the car electric seat under extreme conditions. [0003] At present, the horizontal adjustment devices of automobile electric seats are all driven by high-speed motors, which generate a lot of heat. Long-term operation will lead to higher wear of the transmission device, shorter life, and poorer reliability, making it unsatisfactory for high safety. , High reliability automotive parts require...
