Description

Technical Field

[0001] This utility model belongs to the field of parking technology for three-wheeled electric vehicles and motorcycles, and specifically relates to a parking structure. Background Technology

[0002] In the field of parking systems for three-wheeled electric vehicles and motorcycles, existing parking structures mostly adopt electronic control or a hybrid electromechanical design. These designs have many shortcomings. On the one hand, electronically controlled parking systems rely on the vehicle's electrical system and complex electronic circuitry, making them susceptible to external environmental factors such as water, dust, and electromagnetic interference, leading to system malfunctions or failures. Especially under humid or extreme temperature conditions, the reliability of electronic components will be significantly reduced, potentially causing the parking function to fail and posing safety hazards to the vehicle and rider. On the other hand, most of these parking systems require the rider to support the vehicle with both feet or one foot on the ground to perform the parking operation. This increases rider fatigue and inconvenience when encountering red lights or making temporary stops, especially during long periods of waiting, as the rider needs to maintain a position with both feet or one foot on the ground, preventing them from getting sufficient rest.

[0003] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0013] The following describes the technical effects of each technical feature of this parking structure:

[0014] 1. The purely mechanical design, which combines the control handle, cable, and parking lock, allows for convenient and quick parking. When the rider needs to stop, they operate the control handle to extend the telescopic column into the locking groove, thereby locking the position of the swing arm and keeping the vehicle in a stable parking state. This eliminates the need for the rider to place both feet on the ground for support, improving the convenience and safety of parking. It can effectively reduce rider fatigue, especially when encountering red lights or making temporary stops.

[0015] 2. The protrusion design increases the structural strength of the locking part, while the flared design facilitates the smooth insertion of the telescopic column into the locking groove, improving the accuracy and reliability of parking operations. Even if the vehicle shakes slightly or there is a slight deviation in the position of the swing arm, the telescopic column can accurately enter the locking groove, ensuring the stability of parking.

[0016] 3. The return spring helps the telescopic column return to its original position. When parking, operating the control handle slacks the cable, and the return spring causes the telescopic column to extend into the control unit, keeping the vehicle in a stable parking position. When releasing the parking position, operating the control handle pulls the cable to retract the telescopic column, disengaging it from the locking mechanism, allowing the swing arm to move freely.

[0017] 4. The connections between the cables, telescopic poles, and control handles are all designed to be detachable for easy maintenance.

[0018] 5. The control handlebars are mounted on the handlebars, which are in turn mounted on the bottom bracket. This design allows the rider to easily park the bike while riding using only one hand.

[0019] 6. The tension of the cable can be changed by rotating the control handle, which makes the telescopic column easy to control. Attached Figure Description

This application proposes a parking structure for the aforementioned three-wheeled electric vehicle or motorcycle, including a control handlebar 200, a cable 300, and a parking lock.

[0037] The parking lock includes a control unit 400 mounted on the frame 100 and a locking unit 500 mounted on the swing arm 130. The control unit 400 is equipped with a resettable telescopic column 410, and a control handle 200 is connected to the telescopic column 410 via a cable 300. The locking unit 500 has a locking groove 501. When the swing arm 130 is horizontal, the telescopic column 410 is aligned with the locking groove 501. The control handle 200 controls the telescopic column 410 to extend into the locking groove 501 to achieve the parking function. The purely mechanical design, combining the control handle 200, cable 300, and parking lock, allows for convenient and quick parking. When the rider needs to stop, he operates the control handle 200 to extend the telescopic column 410 into the locking groove 501, thereby locking the position of the swing arm 130, so that the vehicle can be kept in a stable parking state without the rider having to put both feet on the ground for support, which improves the convenience and safety of parking, especially when encountering red lights or temporary parking, it can effectively reduce the rider's fatigue.

[0038] In addition, a protrusion 502 is provided on the locking part 500, and a locking groove 501 is located in the middle of the protrusion 502. The locking groove 501 is flared on the side facing the telescopic column 410. The design of the protrusion 502 can increase the structural strength of the locking part 500, while the flared design makes it easy for the telescopic column 410 to smoothly extend into the locking groove 501, improving the accuracy and reliability of parking operation. Even if the vehicle shakes slightly or there is a slight deviation in the position of the swing arm 130, the telescopic column 410 can accurately enter the locking groove 501, ensuring the stability of parking.
