Description

Technical Field

[0001] This utility model relates to the field of non-motorized vehicles, specifically to a three-wheeled scooter. Background Technology

[0002] Most electric tricycles on the market only lock the rear wheel, not the front wheel, making them easy to lose. Alternatively, the front wheel lock is installed on the front wheel, which is aesthetically unappealing. Utility Model Content

[0003] The technical problem solved by this utility model is that the vehicle lock is mounted on the front wheel, which damages the aesthetics of the vehicle.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a locking drive mechanism for an electric tricycle scooter, comprising a lead screw mounted on a base, a lead screw nut cooperating with the lead screw, and a slide connected to the lead screw nut. The slide is fixedly connected to a splitter, and the splitter is fixedly connected to a brake cable. A motor is mounted on the base, and the motor drives the lead screw through a transmission mechanism, which is located in the base.

[0005] The base of this invention can be installed on the frame, the handlebars, or the brake bus. The motor is started by the scooter control panel. The motor drives the lead screw to rotate, which in turn drives the lead screw nut and the slide to rise, pulling the brake cable. The brake cable then pulls the brake device, which locks the wheels.

[0006] A lead screw seat is fixedly mounted on the base. The lead screw seat has a vertical shaft hole. The bottom of the lead screw is pivotally connected to the vertical shaft hole via a bearing. The bottom end of the lead screw extends downward into the base. The lead screw nut is connected to the shaft. The shaft is fixedly connected to the top plate. The top plate is fixedly connected to the slide. The motor drives the lead screw to rotate, the lead screw drives the lead screw nut, the lead screw nut drives the shaft to rise, the shaft drives the top plate to rise, the top plate drives the slide to rise, the slide drives the distributor to rise, and the brake cable is pulled upward.

[0007] The shaft is hollow, and its bottom is fitted onto a lead screw nut. The shaft and lead screw nut are interference-fitted, and the lead screw extends into the shaft. Only when the shaft and lead screw nut are fixedly connected, and the shaft is also fixedly connected to the slide, can the lead screw rotate to drive the lead screw nut to move up and down linearly.

[0008] A slider is installed on the outer wall of the lead screw seat. The slide table and the slider move together, and the slider guides the slide table, which moves up and down linearly along the slider.

[0009] The brake cable is fixed to the splitter by a locking bolt and a locking block. Specifically, the locking bolt presses down on the locking block, and the locking block presses the brake cable firmly onto the splitter.

[0010] Sensors are located on the side walls of the base, and sensor accessories are located on the bottom of the slide. As the slide descends, the sensor accessories send a signal to the main control unit on the control panel; as the slide rises, the sensor accessories send another signal to the main control unit. The main control unit uses these two different signals to activate different colored lights or sound an alarm on the control panel to indicate to the user whether the scooter is locked.

[0011] Compared to existing technologies where the lock is located on the front wheel, this invention adds a locking drive mechanism without compromising the overall structure of the scooter. The installation location of this locking drive mechanism is optional, achieving both aesthetic appeal and practicality. Attached Figure Description

[0027] Combination Figure 2 , Figures 4 to 6 A locking drive mechanism for an electric tricycle includes a lead screw 20 mounted on a base 10, a lead screw nut 21 cooperating with the lead screw, and a slide 30 connected to the lead screw nut. The slide is fixedly connected to a splitter 40, and the splitter is fixedly connected to a brake cable 41. A motor 50 is mounted on the base, and the motor drives the lead screw through a transmission mechanism, which is located in the base.

[0028] A lead screw seat 60 is fixedly installed on the base 10. The lead screw seat has a vertical shaft hole. The bottom of the lead screw 20 is pivotally connected to the vertical shaft hole through a bearing 22. The bottom end of the lead screw extends downward into the base 10. The lead screw nut 21 is connected to the shaft 23. The shaft is fixedly connected to the top plate 31. The top plate is fixedly connected to the slide table 30.

[0029] Shaft 23 is hollow, and the bottom of the shaft is fitted onto lead screw nut 21. The shaft and lead screw nut are interference-fitted, and lead screw 20 extends into the shaft.

[0030] like Figure 3 A slider 61 is installed on the outer wall of the lead screw seat 60, and the slide table 30 is in movable cooperation with the slider.

[0031] like Figure 6 The brake line 41 is fixed to the splitter 40 by the locking bolt 42 and the locking block 43.

[0032] like Figure 1 The base 10 has a sensor 70 on its side wall and the slide 30 has a sensor accessory on its bottom.

[0033] The base 10 can be mounted on the frame, handlebars, or brake bus. The user starts the motor 50 via the control panel. The motor drives the lead screw 20 to rotate through the transmission mechanism in the base 10. The lead screw drives the lead screw nut 21, which in turn drives the shaft 23 to rise. The shaft then drives the top plate 31 to rise, which in turn drives the slide 30 to rise. The slide then drives the cable divider 40 to rise, pulling the brake cable 41 upwards. The brake cable pulls the brake device, locking the wheel.

[0034] As the slide 30 rises, the sensor accessory 71 triggers the sensor 70. After receiving the signal, the main control unit sends an interactive message to the user via light or sound, indicating that the car has been locked.

[0035] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
