Description

Technical Field

[0001] The invention relates to the field of automobile accessories, and in particular to an asymmetric long-distance aluminum alloy electric slide rail with an avoidance position. Background Art

[0002] MPV stands for multi-purpose vehicle, which combines the functions of a sedan, a station wagon and a van. The cabin can accommodate 7-8 people and has a certain amount of luggage space. The seats are flexibly arranged and can all be folded or laid down.

[0003] There are many ways to classify MPVs. For example, based on their use, they can be divided into household MPVs and commercial MPVs, and based on the number of seats, they can be divided into 5-seater MPVs and 7-seater MPVs. From the perspective of development platforms, some MPVs are products of sedan platforms, while others are derivatives of light buses.

[0004] MPV is a vehicle model mainly for family users. Passenger cars converted from commercial vans for group customers cannot be regarded as true MPVs. The space of MPV is relatively larger than that of cars with the same displacement. There are also differences in size specifications, but not as detailed as cars.

[0005] Among the current products for long slide rails in the front and middle rows, rolling manual slide rails are the most common. With the popularization of intelligent driving in MPVs, the front and middle row passengers will have more demands for long-distance adjustment and movement, such as from the front row to the back row, from the middle row to the back row, etc. The slide rails on the market are usually transported together with the seat assembly. When installing the slide rails, it is time-consuming and laborious because the slide rails and seats are large in size, heavy in weight, and the operating space is small. Summary of the invention
