Description

Technical Field

[0001] This application relates to the field of gear shifters for electric tricycles, and in particular gear shifters for electric tricycles. Background Technology

[0002] The gear shifter for electric tricycles, also known as the gear shifter assembly, suffers from a common problem in existing technologies: the locking mechanism design often leads to gear slippage after shifting. For example, in the existing patent document "CN 217945435 U Electric Tricycle Gear Shifter," although a locking mechanism is designed to limit the gear lever's movement within a specific arc-shaped groove, and further improvements are made to the lever's fixation, gear slippage still occurs in actual use. Therefore, this electric tricycle gear shifter is proposed to address this issue. Utility Model Content

[0003] To address the issue of gear slippage after shifting gears, the following technical solution is provided: A novel gear shifter for electric tricycles includes a button, a shift lever, a fixed base, a locking plate, a pin, a main frame, a front part of the fixed base, a second pin, a torsion spring, a spring, a spring frame, a steel wire, an arc-shaped plate, and an arc-shaped plate hole. The pin is fixedly mounted on the main frame, and the fixed base is hinged to the main frame via the pin. The fixed base is fixedly connected to the bottom end of the shift lever. A torsion spring is provided at the hinge point between the main frame and the fixed base. The torsion spring is sleeved on the pin, and the pin and torsion spring are passed through and fixed to the fixed base and the main frame. One end of the torsion spring is connected to the fixed base, and the other end is fixed to the main frame.

[0004] A spring frame is hinged inside the fixed base. The locking piece is located inside the spring frame. A spring is sleeved on the locking piece. One end of the locking piece passes through the lower part of the spring frame and abuts against the arc-shaped piece. The other end of the locking piece passes through the upper part of the spring frame and is connected to the steel wire. An arc-shaped hole is opened on the arc-shaped piece.

[0005] Beneficial effects: When shifting gears, this new type of electric tricycle gear shifter has a simple structure and can achieve a good locking function. Press the button, hold the gear lever, and press the gear lever down, so that the gear lever and the fixed seat rotate together through the pin and torsion spring. When rotating, the locking piece slides down along the upper part of the arc-shaped piece until it slides to the position of the arc-shaped piece hole. At this time, due to the elastic force provided by the spring, the locking piece can be pushed into the arc-shaped piece hole for positioning and locking, maintaining the position after shifting gears. Since the locking piece is stuck in the arc-shaped piece hole, it can effectively prevent the gear from slipping out. Attached Figure Description

[0011] like Figure 1-3 As shown, the new type of electric tricycle gear shifter includes a button 1; a pin 1-1; a gear lever head 1-2; a gear lever 2; a fixing seat 3; a locking piece 4; a pin 5; a main frame 6; a front part of the fixing seat 7; a second pin 8; a torsion spring 9; a spring 10; a spring frame 11; a steel wire 12; an arc-shaped piece 13; and an arc-shaped piece hole 14.

[0012] A pin 5 is fixedly installed on the main frame 6, and a fixed seat 3 is hinged to the main frame 6 via the pin 5. The fixed seat 3 is fixedly connected to the bottom end of the stop bar 2.

[0013] A torsion spring 9 is provided at the hinge joint between the main frame 6 and the fixed base 3. The torsion spring 9 is always in a deformed state, providing an upward elastic force for the stop bar 2. The torsion spring 9 is sleeved on the pin 5. The pin 5 and the torsion spring 9 are fixedly connected to the fixed base 3 and the main frame 6. One end of the torsion spring 9 is connected to the fixed base 3, and the other end of the torsion spring 9 is fixed to the main frame 6, realizing rotational installation, while providing elastic force through the torsion spring 9.

[0014] A spring frame 11 is hinged inside the fixed base 3. The locking piece 4 is located inside the spring frame 11. A spring 10 is sleeved on the locking piece 4. One end of the locking piece 4 passes through the lower part of the spring frame 11 and abuts against the arc-shaped piece 13. An arc-shaped hole 14 is opened on the arc-shaped piece 13. The other end of the locking piece 4 passes through the upper part of the spring frame 11 and is connected to the steel wire 12. The other end of the steel wire 12 passes through the stop bar 2 and is connected to the pin 1-1.

[0015] Working principle: such as Figure 1-4As shown, when shifting gears, by holding the gear lever head 1-2 and pressing it down, the gear lever 2 and the fixed seat 3 rotate together via the pin 5 and the torsion spring 9. During rotation, the locking piece 4 slides down along the upper part of the arc-shaped piece 13 until it slides to the position of the arc-shaped piece hole 14. At this time, due to the elastic force provided by the spring 410, the locking piece 4 can be pushed into the arc-shaped piece hole 4 for positioning and locking, maintaining the position after shifting gears. After this process, when the gear needs to be restored, press the button 1 and pull the steel wire 12 to pull the locking piece 4 further upward. The locking piece 4 will then disengage from the arc-shaped piece hole 14. At the same time, press the gear lever 2 upward, and the locking piece abuts against the upper part of the arc-shaped piece, realizing the initial gear reset.

[0016] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
