Technical Field

[0001] This application relates to the field of electric vehicle control technology, and in particular to a two-wheeled electric vehicle control device with remote OTA function. Background Technology

[0002] The annual production of two-wheeled bicycles, which are a common means of transportation for ordinary people, has reached nearly 50 million units. When you add electric two-wheelers for food delivery / express delivery, recreational electric vehicles, electric tricycles, etc., the number is already enormous. The electric vehicle controller is the core control device used to control the start, operation, forward and backward movement, speed, and stop of the electric vehicle motor, as well as other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important part of the electric vehicle.

[0003] Existing electric vehicles generate a lot of heat during use, and heat dissipation is only achieved through vents, which is ineffective. In addition, the electric vehicle controller consists of a control box, a cover, and a control circuit board. However, the cover and the control box are usually connected by screws. When maintaining the control circuit board inside the control box, the cover needs to be removed. The screw connection requires tools for disassembly and installation, which is inconvenient during maintenance.

[0004] Therefore, a two-wheeled electric vehicle control device with remote OTA function is proposed. Utility Model Content

This makes it easier to remove the cover from the control box. Compared with the previous screw installation, no external tools are needed, making it more convenient to use and providing convenience in maintenance and repair. Attached Figure Description

[0029] The implementation principle of a two-wheeled electric vehicle control device with remote OTA function in this application embodiment is as follows:

[0030] First, by installing the control circuit board inside the control box 16 and promptly installing the box cover 15, and placing the box cover 15 above the control box 16, the drive block 28 is rotated. After the drive block 28 rotates, it drives the second inclined plate 26 to rotate. After the second inclined plate 26 rotates, it drives the rotating plate 27 to rotate. After the rotating plate 27 rotates, it drives the first inclined plate 1 to rotate. After the first inclined plate 1 rotates, it drives the slider 14 to move. After the slider 14 moves, it drives the spring 8 to stretch. After the slider 14 moves, it drives the positioning block 20 to move, so that the positioning block 20 is installed inside the connecting groove 24.

[0031] Then, the drive block 28 is released, and the slider 14 moves under the action of the spring 8, so that the positioning hole 18 on one side of the positioning block 20 is installed to the outside of the insert block 23, realizing the quick installation of the cover 15. At the same time, no external tools are needed during disassembly, making it more convenient to use and providing convenience in maintenance and repair.

[0032] Next, during use, the cooling fan 7, in conjunction with the ventilation port 17, can dissipate the high temperature generated inside the control box 16, preventing damage to the equipment due to excessive internal temperature and extending the service life of the electric vehicle controller. At the same time, the handwheel 10 drives the bidirectional lead screw 13 to rotate, and the rotation of the bidirectional lead screw 13 drives the locking block 12 to move and lock the cooling fan 7 after installation, providing convenience for the installation and removal of the cooling fan 7, and also facilitating the maintenance and cleaning of the cooling fan 7.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
