Description

Technical Field

[0001] The utility model relates to the technical field of gear shifters, in particular to a gear shifter for an electric vehicle. Background Art

[0002] The invention relates to a method for operating a gear lever, which is a simple and direct name for a gear shifter. The method is easy to use and has a great impact on the safety of a person driving a car. In particular, the method is easy to use and has a great impact on the safety of a person driving a car. The method is easy to use and has a great impact on the safety of a person driving a car. The invention discloses an anti-slip shifter for electric tricycles, wherein the limiting protrusions between adjacent shift grooves can prevent the shift protrusions from falling out of the shift grooves, and the shift protrusions are further fixed inside the shift grooves by utilizing the rebound characteristics of the spring itself, thereby doubly protecting the shift from falling out and having higher safety. When shifting gears, it is only necessary to apply force to the handle protrusion and control the swing of the connecting rod by the hand ball. However, both do not have the function of pulling back to the closed gear. During operation, the gear position needs to be adjusted manually, which is not convenient for identifying and controlling the change of the gear position according to the pulling force, and is not convenient for accidentally slipping and performing a shift down operation when shifting gears. The gear position is easily increased to an uncontrolled state, and the stability is poor. Therefore, an electric vehicle shifter with an automatic shift down mechanism is designed, which is convenient for increasing and decreasing the shift down elastic pushing force as the gear position increases and decreases. Not only can the shifter automatically shift down when the hand accidentally drops out of the gear during shifting to avoid loss of control, but it is also convenient for increasing and decreasing the gear position according to the change of the automatic shift down pushing force, thereby improving the flexibility of the shifting gear.

[0014] The electric vehicle shifter is provided with a shaft sleeve, a shift rod, a rotating slider and a gear setting mechanism, so that the stopper has the potential energy to push from the adjustment channel to the gear slot in the adjustment channel. When the stopper is aligned with one of the gear slots, it is convenient to snap into the gear slot to set the gear. Through the provision of the automatic gear-reversing mechanism, under the action of the hinge torsion spring and the shaft sleeve, the stopper always has the potential energy to retract when the gear is adjusted, so that when the stopper rotates back and forth in the adjustment channel, the hinge torsion spring is pressed. The rebound force increases accordingly, thereby causing a pushing force on the top of the gear lever. Through the overall cooperation of the gear fixing mechanism and the automatic gear shifting mechanism, the gear is automatically shifted when the hands are accidentally released during gear shifting, thereby avoiding speed loss. The electric vehicle gear shifter has an automatic gear shifting mechanism, which is convenient for increasing or decreasing the gear shifting elastic pushing force as the gear position increases or decreases. Not only can the gear be automatically shifted when the hands are accidentally released during gear shifting, thereby avoiding speed loss, but it is also convenient for increasing or decreasing the gear position according to the change of the automatic gear shifting pushing force, thereby improving the flexibility of the gear shifting.
