Electronic gear detection mechanism based on photoelectric sensors

Abstract

The invention discloses an electronic gear detection mechanism based on photoelectric sensors. The electronic gear detection mechanism comprises an operation rod and a handle base, wherein the operation rod is formed by sequentially connecting an operation handle, a center ball and a telescopic pointed head, the center ball and the telescopic pointed head are arranged in the handle base, a plurality of light shielding baffle plates are uniformly arranged on the center ball in the circumferential direction of the operation rod, a photoelectric sensor group connected with an electronic gear control circuit is respectively arranged in the handle base corresponding to each light shielding baffle plate, and the photoelectric sensor group consists of at least two layers of photoelectric sensors. The electronic gear detection mechanism based on the photoelectric sensors has the advantages that the structure is simple, the manufacture is convenient, the mechanical vibration resistance performance and the electromagnetic interference performance are high, and the mistake triggering can be effectively avoided.

Description

technical field [0001] The invention relates to the automobile electronic gear technology, in particular to an electronic gear detection mechanism based on a photoelectric sensor. Background technique [0002] Compared with the traditional mechanical gear shifter, the electronic gear shifter uses electrical signals to connect the gear shifter and the gearbox. The advantages of the electronic gear shifter are: 1. The installation of the electronic gear shifter is easier and the layout on the vehicle is more flexible; 2. The electronic gear is smaller in size and lighter in weight, which expands the space of the center console, and can provide a unique appearance design according to customer needs; 3. It can prevent damage to the transmission caused by the driver's misoperation of shifting, and more Protect the transmission well and correct the driver's bad shifting habits; 4. The electronic shifter has powerful anti-theft performance. It is completely connected with the compu...

Problems solved by technology

Its disadvantages are: due to the dispersion of the magnetic field of the magnet, the excessively dense magnetic field distribution between the sensors will lead to false triggering. In order to prevent false triggering, the position distribution of the sensors must be accurate, and the mechanism must be small and flexible, which is not suitable for the layout of the sensor. space, so the manufacturing process requires high requirements; as the machine loosens during use, the relative position between the electromagnet and the sensor changes, the sensor that was originally in the trigger state may not be triggered, and the sensor that was not triggered may be If it is triggered, it will affect the shifting effect; mechanical vibration will also cause false triggering of the sensor, and its anti-mechanical vibration performance is poor; electromagnetic interference may also cause false triggering of the sensor, and its anti-electromagnetic interference performance is poor
