Description

Technical Field

[0001] The utility model relates to an electric power-assisted vehicle, in particular to a replaceable motor hanger mechanism of the electric power-assisted vehicle. Background Art

[0002] Electric power-assisted bicycles use electric motors to provide auxiliary driving force. In this type of vehicle, the installation methods of the electric motor include mid-mounted and rear-mounted. The mid-mounted motor is directly fixed to the five-way position of the frame, and the rear-mounted motor is installed in the inner section of the rear triangle hook of the frame. The five-way frame is installed with a sprocket and a five-way bowl. Therefore, the frame must be designed according to different motor installation methods. Basically, a mid-mounted motor frame cannot be installed with a rear motor. The frame as the main structure is not compatible. In the specific design and manufacturing process, different types of frames need to be designed for mid-mounted motors and rear-mounted motors respectively, which increases the design and manufacturing costs of car companies and is not convenient for users to upgrade and transform by themselves. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a replaceable motor bracket mechanism for an electric power-assisted bicycle which has stronger compatibility, can save design and manufacturing costs, and is convenient for later modification, in view of the deficiencies of the existing technology.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0005] A replaceable motor bracket mechanism for an electric power-assisted vehicle comprises a frame, a mid-mounted motor and a five-way fixing seat. A receiving opening is provided at the five-way position of the frame. Both the mid-mounted motor and the five-way fixing seat can match the receiving opening. A rear motor controller is installed in the five-way fixing seat. Either the mid-mounted motor or the five-way fixing seat is installed in the receiving opening.

[0006] Preferably, the accommodating opening is a step opening opened on the left side or the right side of the frame.

[0007] Preferably, the central motor and the five-way fixing seat can be selectively installed in the accommodating opening by means of screws.

[0008] Preferably, a left cover plate and a right cover plate are fixed to the left and right sides of the five-way fixing seat respectively.

[0009] Preferably, a fixing cavity is provided in the five-way fixing seat, and the rear motor controller is arranged in the fixing cavity.

[0010] In the replaceable motor bracket mechanism of the electric power-assisted bicycle disclosed by the utility model, the accommodating opening is opened at the five-way position of the frame, and the opening shape of the accommodating opening matches the outer contours of the center-mounted motor and the five-way fixing seat, so that the center-mounted motor and the five-way fixing seat can be installed in the accommodating opening, and can be detachably installed by screws or other means, thereby meeting the center-mounted installation requirements or rear-mounted installation requirements of the motor. Compared with the prior art, the utility model is not only more compatible, but also can effectively save design and manufacturing costs, and also facilitates users' later modifications and upgrades, and better meets user needs and market demands.

[0018] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0019] The utility model discloses a replaceable motor bracket mechanism for an electric power-assisted vehicle, combined with Figures 1 to 5 As shown, it includes a frame 1, a mid-mounted motor 2 and a five-way fixing seat 3. The five-way position of the frame 1 is provided with a receiving opening 10. Both the mid-mounted motor 2 and the five-way fixing seat 3 can be matched with the receiving opening 10. The five-way fixing seat 3 is used to install a rear motor controller 5. Either the mid-mounted motor 2 or the five-way fixing seat 3 is installed in the receiving opening 10.

[0020] In the above structure, the accommodating opening 10 is opened at the five-way position of the frame 1, and the opening shape of the accommodating opening 10 matches the outer contours of the mid-mounted motor 2 and the five-way fixing seat 3, so the mid-mounted motor 2 and the five-way fixing seat 3 can be installed in the accommodating opening 10, and can be detachably installed using screws or other methods, thereby meeting the mid-mounted installation requirements or rear-mounted installation requirements of the motor. Compared with the prior art, the utility model is not only more compatible, but also can effectively save design and manufacturing costs, and also facilitates users' later modifications and upgrades, and better meets user needs and market demands.

[0021] In this embodiment, the receiving opening 10 is a stepped opening opened on the left or right side of the frame 1. In practical applications, the central motor 2 or the five-way fixing seat 3 can be aligned with the receiving opening 10 from the side, and the mounting holes are aligned, and then fixed and assembled.

[0022] As a preferred detachable fixing method, in this embodiment, the central motor 2 and the five-way fixing seat 3 can be installed in the accommodating opening 10 by screws 4.

[0023] In order to provide a lateral covering effect for the five-way fixing seat 3, in this embodiment, see Figure 4 , Figure 6 , Figure 7 A left cover plate 30 and a right cover plate 31 are fixed to the left and right sides of the five-way fixing seat 3 respectively.

[0024] In this embodiment, the rear motor controller 5 can be hidden in the five-way fixing seat 3. For this, please refer to Figure 5 A fixing cavity 32 is defined in the five-way fixing seat 3 , and the rear motor controller 5 is disposed in the fixing cavity 32 .

[0025] The electric power-assisted vehicle disclosed in the utility model has a replaceable motor bracket mechanism, which is based on the electric power-assisted vehicle frame of the central motor, and is assembled to the inside of the motor bracket through a five-way device and the motor bracket of the electric power-assisted vehicle frame of the central motor. The five-way device is a hollow structure, and there is a controller installation space for the rear motor and a five-way device locking circular hole and a fixing screw group inside. After the five-way device is installed to the electric power-assisted vehicle structure of the central motor, the electric power-assisted vehicle frame of the central motor can be compatible with the installation mode of the rear motor, which is convenient for consumers to modify and use, and can reduce configuration costs. At the same time, it can reduce the mold development of the frame structure, so that the frame is compatible with the central motor and the rear motor to share the use of the central motor frame. In addition, because the five-way device in the utility model is a hollow structure feature, a controller can be placed inside. After the wires are connected, the left cover and the right cover can be closed, and the small five-way inside the five-way device can be installed with the sprocket and five-way bowl of an ordinary vehicle model, and the frame utilization rate is improved. When the five-way device is removed, a mid-mounted motor can also be installed to change the function of the frame. The frame is called a mid-motor electric power-assisted vehicle. Or, if the mid-mounted motor is damaged during use, the consumer can add this five-way device to convert it to a rear-mounted motor. The structure of the frame's five-way device is smooth and simple, and the repair and maintenance manufacturing costs are lower.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
