Description

Technical Field

[0001] This utility model relates to the field of electric-assisted bicycles, and in particular to the structure of a mid-mounted motor battery base and controller for electric-assisted bicycles. Background Technology

[0002] In the existing technology of electric-assist bicycles, the structural design of the battery base and controller in a mid-drive motor system has the following technical problems:

[0003] Large space occupation: In the existing battery lower tube structure, the battery base is connected to the controller through a wiring harness, resulting in a loose system layout and a large space occupation, which is not conducive to the lightweight and compact design of vehicles.

[0004] Poor controller reliability: Traditional mid-drive systems integrate the controller inside the mid-drive motor, which is subject to the high temperature and oil and gas pollution generated by the motor operation for a long time, making it prone to failure. Moreover, the motor must be disassembled for maintenance, which must be done by professional personnel, making maintenance difficult and costly.

[0005] Insufficient modularity: The existing structure is difficult to adapt to different battery models through standardized design, resulting in low modularity and poor flexibility in production and maintenance. Utility Model Content

[0006] This application provides a structure for the battery base and controller of a mid-drive motor in an electric-assist bicycle. This addresses the problems of existing battery lower tube structures where the battery base is connected to the controller via a wiring harness, resulting in a loose system layout, large space occupation, and hindering lightweight and compact vehicle design. Furthermore, traditional mid-drive systems integrate the controller within the mid-drive motor, subjecting it to long-term exposure to high temperatures and oil / gas contamination from motor operation, making it prone to malfunctions. Repairs also require disassembly of the motor, necessitating professional personnel and resulting in high repair difficulty and cost. Additionally, existing structures struggle to adapt to different battery lower tube models through standardized design, leading to low modularity and poor flexibility in production and maintenance.

[0007] The technical solutions adopted in the embodiments of this application are as follows.

[0008] A structure for a battery base and controller for a mid-mounted motor of an electric-assist bicycle includes a battery, a battery mounting base, a controller, a male discharge port, and a lower battery tube. The male discharge port is connected to the battery mounting base via a first set of screws. The controller is connected to the battery mounting base via a second set of screws. The assembly of the battery mounting base and the controller is inserted into a designated position on the lower battery tube and fixed to the lower battery tube by a third and a fourth screw.

[0009] As a further improvement to the above technical solution: the first screw group includes 4 screws for fixing the male discharge port to the battery mounting base.

[0010] As a further improvement to the above technical solution: the second screw group includes 4 screws for fixing the controller to the battery mounting base.

[0011] As a further improvement to the above technical solution: the third screw and the fourth screw are used to fix the assembly to the lower tube of the battery.

[0012] As a further improvement to the above technical solution: the structure of the battery fixing base is designed to be compatible with different models of battery lower tubes.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] 1. Because the controller is integrated with the battery mounting base, there is no need to find a separate installation location for the controller; the process of installing the controller separately is eliminated; by changing different battery mounting bases, different models of battery tubes can be adapted, achieving a modular design and making controller maintenance convenient; by installing the controller in a designated position on the battery tube, the controller's working environment (temperature, oil and gas pollution) is improved, reducing the risk of failure and increasing reliability; the internal integration of the mid-mounted motor is reduced, the structure is simpler, and the system stability is improved.
