Problems solved by technology

[0002] In the traditional automobile electric door lock device, a single-thread transmission shaft is used to drive the pull rod, but some cars require a relatively fast movement speed of the pull rod. It is difficult to realize the existing single-thread drive shaft. Ultrasonic welding of the upper and lower covers, this welding method has high cost, low efficiency and is not reliable

Abstract

The invention relates to an automobile electric door lock device comprising an upper lid, a pull rod, a transmission shaft, a middle gear, a small gear, a central spindle, a small motor, a protective sleeve and a lower lid. The upper lid is fixed on the lower lid; one end of the lower lid is provided with the pull rod and the other end is provided with the protective sleeve; the small motor is disposed in the lower lid; the small motor drives the small gear; the small gear drives the middle gear; the middle gear is connected with the transmission shaft; the transmission shaft is connected with the pull rod; and the middle gear is fixed on the lower lid via the central spindle. The automobile electric door lock device is simply structured and rationally designed; on one hand, a traditional single-thread transmission shaft is changed into a three-thread transmission shaft; with the improvement, motion speed of the pull rod is improved by three times; on the other hand, a traditional way of welding the upper lid and the lower lid via a welding way is changed into a buckling technology, so the upper lid and the lower lid can be buckled together; the upper lid and the lower lid can be fixed with firmness and beautiful contour; and the upper lid and the lower lid cannot fall; and the automobile electric door lock device is easy to assemble and adjust.

Description

【Technical field】 [0001] The invention relates to an automobile electric door lock device, which belongs to the technical field of automobile electric door locks. 【Background technique】 [0002] In the traditional automobile electric door lock device, a single-thread transmission shaft is used to drive the pull rod, but some cars require a relatively fast movement speed of the pull rod. It is difficult to realize the existing single-thread drive shaft. Ultrasonic welding of the upper and lower covers, this welding method has high cost, low efficiency and is not reliable. 【Content of invention】 [0003] The object of the present invention is to provide a kind of automobile electric door lock device with simple structure, reasonable design and convenient use in view of the defects and deficiencies of the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A kind of automobile electric door lock device...
