Problems solved by technology

[0002] Most of the existing similar products adopt pneumatic type (such as Mercedes-Benz S series, BMW 7 series, Audi A8 and other models), which have many disadvantages: the door lock body mechanism is extremely complicated, and the manufacturing process requirements are relatively high; the door lock is large in size, It is only suitable for high-end models with wide doors; the vehicle needs to add an air pump device to give power to the door lock when the door is assisted in closing
The cost is high; the failure rate is high, and the maintenance is difficult; among similar products, the electric ones mostly use gears or fan-shaped racks for transmission. The biggest disadvantage is: huge size! It can only be used on the trunk with sufficient installation space (such as: the trunk lock body installed on the Nissan Quest model)
Not suitable for tight spaces inside driver and other passenger doors
