Small, simple and lightweight electronic gear shifter

Abstract

The small, simple and lightweight electronic gear shifter comprises an upper shell and a lower shell, the upper end part of the lower shell is inserted into the upper shell to be matched with a semicircular hole in the top of the upper shell to form a whole circular hole, a gear shifting assembly comprises a gear shifting rod, a gear pin and a spiral spring, and two concentric cylindrical parts are symmetrically arranged at the two ends of the middle of the gear shifting rod; the gear shifting rod is rotatably installed in the two full round holes through the two concentric cylindrical parts, the spiral spring is arranged on the tail portion of the gear pin in a sleeved mode, the gear pin is elastically and slidably placed in a blind hole of the gear shifting rod, and the head portion of the gear pin is in sliding connection with the inner tooth shape of the lower shell. And one side of the lower end of the gear shifting rod extends outwards to form a shifting fork coated with a magnet. Supporting parts such as a lining and a pressing plate are omitted, the size error caused by assembly of numerous parts is effectively reduced, and the problem of gear shifting clamping stagnation caused by a screw locking fulcrum is avoided; and meanwhile, the shaking amount and the lagging feeling of the gear shifting rod during gear shifting are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile shifters, in particular to a small, compact and lightweight electronic shifter. Background technique [0002] With the rapid development of network technology, intelligent driving technology has become more and more mature, and electronic shifters have become the first choice of major domestic and foreign automobile manufacturers. With the development of electronic gear shifters, the need for lighter weight of the whole vehicle is getting higher and higher. The volume and weight of the existing electronic gear shifters can no longer meet the requirements of automobile use. Therefore, our company has developed an electronic gear shifter (application number 2021102191836), the electronic shifter includes an upper casing, a lower casing, and a magnet, a shift lever, a spherical bush, a pressure plate, a return spring, a gear mounted in the cavity surrounded by the upper casing and the lower casing...

Problems solved by technology

With the development of electronic shifters, the need for lightweight vehicles is getting higher and higher. The volume and weight of existing electronic shifters can no longer meet the requirements of automobile use. For this reason, our company has developed an electronic shifter (application number 2021102191836), the electronic shifter includes an upper housing, a lower housing, and a magnet installed in the cavity surrounded by the upper housing and the lower housing, a shift lever, a spherical bush, a pressure plate, a return spring, a gear Multiple components such as pins and circuit boards, the upper case and the lower case are detachably connected, the shift lever is rotatably installed in the upper case through the spherical bush and the pressure plate, and the lower end of the shift lever extends into the lower case to connect the gear Position pin, the gear pin is slidably set in the cavity at the lower end of the shift lever through the return spring, and its head is slidably connected with the shift tooth groove of the lower housing; the magnet is set on the upper part of the shift lever, driven by the shift lever Its position changes, so that the circuit board outputs the gear signal

[0003] Although the above-mentioned electronic shifter has simplified the parts and reduced the weight, there are still many problems such as large size and cooperation of multiple parts, which cause the shifter to stick and shake.
