Description

Technical Field

[0001] This utility model relates to the technical field of gear shifters, specifically to a gear shifting mechanism for electric vehicles. Background Technology

[0002] Existing anti-disengagement gear shifters use two fixed springs to achieve gear changes by utilizing the extension and contraction of the springs. They adjust the gear position by using the spring principle. When the springs are old or the tension is not appropriate, various situations may occur when shifting gears, such as forward / backward movement. It is easy to shift to the wrong gear, or even involuntary gear changes, which may cause personal injury and vehicle danger.

[0003] In implementing this embodiment, the inventors discovered at least the following problems:

[0004] Existing anti-disengagement gear shifters have structural deficiencies, which can accelerate the damage of springs and reduce the service life of the gear shifter.

[0005] The existing anti-disengagement gear shifter rubber sleeve is not fixed, and it moves up and down during gear shifting, which can easily cause the hand to slip, potentially leading to gear shifting errors and causing danger to people or vehicles.

[0006] The existing anti-disengagement gear shifter has too small a hand position, making it easy to slip in rainy or snowy weather. When the vehicle is going uphill or driving, it is easy to cause gear shifting errors, which may cause danger to people or vehicles. Utility Model Content

A gear shifting connector is sleeved on the outer side of the gear shift lever, and a handle is fixedly installed on the upper side of the gear shift lever. A spring is set between the gear shifting connector and the handle. When a gear shift is required, the driver can pull up the upper lifting position of the gear shifting connector to compress the spring, raise the gear shifting connector to a limited area, and push the gear shift lever so that the gear shift lever moves according to a preset waist-shaped track. After reaching the preset position, the gear shifting limit piece is released, and the elastic deformation pressure of the spring pushes the gear shifting connector to the designated position, thereby completing the gear shifting action.

[0026] The upper end of the silicone sleeve is installed and fixed at the locking position of the shift connector to ensure that the silicone sleeve will not move up and down during shifting and to prevent rain and snow from entering the shifting area, causing shifting errors or slippage.

Specific details such as particular configurations and components are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0037] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0038] like Figures 1-6 The diagram shows a gear shifting mechanism for an electric vehicle provided in this embodiment, including: a shift lever 100, a shift connector 200, and a base bracket 300; the shift lever 100 is rotatably mounted on the base bracket 300 via a pin 110; the shift lever 100 passes through the shift connector 200; locking pins 210 are provided on both sides of the shift connector 200; movable tracks 310 are provided on both sides of the base bracket 300; the movable tracks 310 are connected to a corner 311; the locking pins 210 are confined within the movable tracks 310.

[0039] Specifically, when the shift connector 200 is lifted upwards, causing the locking pin 210 to disengage from the corner 311 of the movable track 310, the shift connector 200 is repeatedly pushed and pulled, and the shift lever 100 will rotate around the pin 110 as the axis. The positioning pin on the shift connector 200 will move repeatedly within the movable track 310 to achieve the shifting action.

[0040] Furthermore, a base 320 is fixedly connected to one side of the base bracket 300, a silicone sleeve 400 is placed on the base 320, and a pressure plate 500 is installed on the silicone sleeve 400. By installing fasteners on the pressure plate 500, the silicone sleeve 400 is fixed to the base 320.

[0041] Furthermore, a handle 120 is fixedly installed at the end of the shift lever 100. The handle 120 and one end of the shift connector 200 form a receiving space 220.
