Description

Technical Field

[0001] This utility model relates to a drive-break structure for the main support frame of an electric vehicle, belonging to the field of safety technology for two-wheeled electric vehicles. Background Technology

[0002] Most current two-wheeled electric vehicles have both side support kickstands and main support kickstands. The side support kickstands are mainly used for short-term parking scenarios such as temporary parking on the roadside. In this case, the rider may forget to turn off the power. Therefore, when the side support kickstand is raised or lowered, the power output of the whole vehicle will be turned off and on through the power-off switch. This can effectively prevent the vehicle from starting unexpectedly, thereby avoiding the safety problems of electric vehicles being parked statically without being turned off.

[0003] When the main support stand is in place, the rear wheel of the electric vehicle is usually not in contact with the ground, so existing electric vehicles generally do not shut off the power output at this time. However, when the rear rack of the electric vehicle is carrying heavy objects, or when the electric vehicle is slightly tilted, the rear wheel may still be in contact with the ground. In this case, if the throttle is turned carelessly after the main support stand is in place, the electric vehicle may accidentally lurch forward, causing a hazard.

[0004] To completely solve the safety problem of electric vehicles when parked statically without power interruption, the existing main support frame structure is improved. When the main support frame of the electric vehicle is raised (lowered), the power output of the whole vehicle is disconnected, and when the main support frame is retracted, the power output of the whole vehicle is restored. However, the space at the main support frame is relatively small, so how to install a power-off switch in the small space has become an urgent problem to be solved.

[0005] The applicant's search revealed that Chinese Patent CN213199939U discloses a main support frame with a power-off switch. The frame has two hinged sections, one of which has a power-off switch on its outer side. The power-off switch includes an inner ring and a positioning part located on the outer periphery of the inner ring. The inner ring is positioned on the hinged section and has a first contact. A second contact is located on the inner surface of the positioning part that contacts the inner ring. When the support frame rotates, the first contact on the inner ring either contacts or de-contacts the second contact, thus switching the electric vehicle control circuit on and off. However, this main support frame, which uses the rotation of the inner ring and the support frame to open and close the power-off switch, is a novel support frame structure and cannot be implemented on existing electric vehicle main support frames. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to propose a drive-break structure applicable to the existing main support frame of electric vehicles, which can solve the safety problem of existing electric vehicles when they are statically parked without power disconnection.

[0007] To solve the above-mentioned technical problems, this utility model proposes a main support leg disconnection structure for electric vehicles. The frame of the electric vehicle is provided with a main support mounting plate, and the rotating shaft of the main support leg is set on the main support mounting plate.

[0008] The drive-off structure includes a power-off switch and a mounting bracket. The mounting bracket includes a U-shaped groove section and a forward extension section. The U-shaped groove section matches the shape of the main support mounting plate and partially surrounds the main support mounting plate. The forward extension section extends from the bottom of the U-shaped groove section toward the front of the vehicle.

[0009] The U-shaped groove section has a through hole that matches the rotating shaft, and a first threaded fastener for connecting the mounting bracket and the main support mounting plate;

[0010] The power-off switch is installed below the forward extension section via a second threaded fastener. The contacts of the power-off switch cooperate with the main support leg. When the main support leg is lowered, the main support leg abuts against the contacts of the power-off switch, causing the power-off switch to open. When the main support leg is retracted, the main support leg moves away from the contacts of the power-off switch, causing the power-off switch to close.

[0011] This invention fully utilizes the gap between the main support bracket and the electric vehicle frame to fix the mounting bracket on the main support mounting plate. The forward extension of the mounting bracket extends towards the front of the vehicle, thus providing space for installing a power-off switch. The contacts of the power-off switch cooperate with the main support bracket. The power-off switch is activated and deactivated by raising and lowering the main support bracket, achieving the design of turning the vehicle's power output off and on. That is, when the main support of the electric vehicle is lowered, the power-off switch is activated by the main support, which disconnects the power output of the entire vehicle. When the main support is raised, the power output of the entire vehicle is restored. This invention can be used to modify existing electric vehicles or applied to newly manufactured electric vehicles, thereby solving the safety problem mentioned in the background art when electric vehicles are statically parked without being powered off.

[0018] like Figure 1 and Figure 2 As shown, existing two-wheeled electric vehicles typically have two downward-extending main support mounting plates 2 (arranged in parallel) below the frame 1, and the pivot 5 of the main support leg 4 is mounted on the two main support mounting plates 2.

[0019] This embodiment illustrates a drive-break structure for the main support leg of an electric vehicle, such as... Figures 1-4 As shown, the device includes a power-off switch 8 and a mounting bracket 3. The power-off switch 8 is connected to the electrical circuit of the electric vehicle via a wire. The mounting bracket 3 includes a U-shaped groove section 3-1 and a forward extension section 3-2. The U-shaped groove section 3-1 matches the shape of the main support mounting plate 2 and partially surrounds it. The forward extension section 3-2 extends from the bottom of the U-shaped groove section 3-1 towards the front of the vehicle. The mounting bracket 3 is fixed to the frame via the U-shaped groove section 3-1, and the power-off switch 8 is mounted via the forward extension section 3-2, making full use of the narrow space between the main support bracket 4 and the frame 1. Preferably, to improve connection strength, such as... Figure 4 As shown, a reinforcing rib 3-4 is provided between the U-shaped groove section 3-1 and the forward extension section 3-2.

[0020] The U-shaped groove section 3-1 has a through hole that matches the rotating shaft 5, and a first threaded fastener 6 for connecting the mounting bracket 3 and the main support mounting plate 2. In implementation, the two side skirts of the U-shaped groove section are tightly fastened to the main support mounting plate, and the bottom surface of the U-shaped groove section is in contact with the main support mounting plate. The mounting bracket is initially fixed by the cooperation of the rotating shaft and the through hole (the rotating shaft is inserted into the through hole), and then a second fixation is performed by the first threaded fastener 6 to ensure the reliability of the connection between the mounting bracket 3 and the main support mounting plate 2. The first threaded fastener 6 can be a combination of bolts and nuts.

[0021] The power-off switch 8 is installed below the front extension section 3-2 via the second threaded fastener 7. The contacts of the power-off switch 8 cooperate with the main support bracket 4. When the main support bracket 4 is lowered, it abuts against the contacts of the power-off switch 8, causing the power-off switch 8 to open and disconnecting the power output of the entire vehicle. When the main support bracket 4 is retracted, it moves away from the contacts of the power-off switch 8, causing the power-off switch 8 to close and restoring the power output of the entire vehicle. This minimizes the safety issues that may arise when the electric vehicle is parked statically without power being disconnected.

[0022] To protect the power-off switch, preferably, the end of the forward extension 3-2 near the front of the vehicle is provided with a downwardly bent protective section 3-3, which does not contact the power-off switch. In implementation, there is a certain gap between the protective section and the power-off switch, which can protect the power-off switch from collisions with foreign objects and extend the service life of the power-off switch.

[0023] This embodiment can also be improved as follows: 1) The power-off switch 8 is a waterproof power-off switch, which can prevent water from entering and damaging the power-off switch in rainy or snowy weather. 2) The U-shaped groove section 3-1, the extension section 3-2, and the protection section 3-3 of the mounting bracket 3 are integrally formed, for example, by using a bent part, which makes the structure more stable and reduces production costs; of course, the U-shaped groove section, the extension section, and the protection section can also be set independently and connected by fasteners.
