Description

Electric slide rail screw rod support of automobile seat

Technical Field

The utility model relates to a car seat slide rail field especially relates to an electronic slide rail lead screw support of car seat.

Background

The horizontal adjustment of the electric slide rail of the automobile seat is mainly realized through a screw rod and a speed reducing mechanism. The speed reducing mechanism is arranged in the gear box; the screw rod is fixed on the lower slide rail through the front bracket and the rear bracket. In the prior art, the screw rod and the front support are assembled in a threaded connection mode, the mode needs to be installed by adopting special equipment for the screw rod, and the defects of the mode are as follows: 1. the special equipment for the screw rod has high cost, and the electric slide rail for the automobile seat is a product assembled in a large quantity, needs to be matched with a plurality of special equipment for the screw rod, wastes the space of a factory building and increases the production cost; 2. after the screw rod is in threaded connection with the front support, the height of the screw rod is fixed, when a gear box bearing the weight of a seat and passengers horizontally moves on the screw rod, the screw rod can deform downwards, so that abnormal sound is generated by meshing of the gear box and the screw rod, and particularly when the gear box moves to be close to the front support, due to the fact that no up-and-down floating space exists between the screw rod and the front support, the abnormal sound is more serious, customer experience is affected, customer complaints are increased, abrasion of gears of a speed reducing mechanism in the screw rod and the gear box is increased, and the service life of a product is further shortened; 3. after the front bracket and the rear bracket are assembled with the lower slide rail, the straightness of a single screw rod is deteriorated due to the coaxiality deviation of the front bracket and the rear bracket, and the parallelism between the two screw rods is also deteriorated due to the adoption of two parallel screw rods below the seat; especially when the gearbox is moved close to the front bracket, the motor needs to provide more power to overcome more resistance, which also affects the life of the motor.

Disclosure of Invention

The utility model discloses to prior art's not enough, develop an automobile seat electric slide rail screw rod support. The utility model adopts the technical proposal that: an electric slide rail screw rod bracket of an automobile seat is characterized by comprising a screw rod 1, a rubber pad 2, a clamping ring 3, a front bracket 4, a rear bracket 5, a bolt 6 and a gear box 7; the front bracket 4 is provided with a through hole; the rubber pad 2 is inserted into the through hole on the front bracket 4; the front end of the screw rod 1 is inserted into the rubber pad 2; the clamping ring 3 is clamped into the front end of the screw rod 1; the rear end of the screw rod 1 is inserted into the rear bracket 5 and is fixed by the bolt 6; the gear box 7 is meshed with the screw rod 1.

The utility model discloses an useful part embodies: 1. due to the adoption of the assembly mode that the front end of the screw rod is inserted into the front bracket, special equipment for the screw rod is not needed, the screw rod can be manually inserted and clamped into the card for fixing, the cost for purchasing the special equipment for the screw rod is saved, and the space of a factory building is also saved; 2 because the rubber pad is arranged between the screw rod and the through hole of the front bracket, a certain floating space is arranged between the screw rod and the front bracket, when the weight of the seat and passengers is applied to the screw rod through the gear box, the screw rod can be buffered to a certain degree, the downward deformation of the screw rod is reduced, abnormal sound is reduced, customer experience is improved, customer complaints are avoided, the abrasion of the screw rod and a gear of a speed reducing mechanism in the gear box is reduced, and the service life of a product is prolonged; 3. after the front support and the rear support are assembled with the lower sliding rail, due to the fact that a certain floating space is formed between the screw rod and the front support, even if the coaxiality of the front support and the rear support is deviated, the straightness of a single screw rod can be well maintained, further, the parallelism between the two screw rods is also good, and the motor can guarantee smooth operation without providing high power.
