Description

Technical Field

[0001] This utility model belongs to the technical field of electric motorcycle components, and relates to an electric motorcycle frame, particularly an electric motorcycle frame. Background Technology

[0002] Electric motorcycles are not only used as a means of transportation but also provide people with the enjoyment of exercise. The frame, as a crucial component of an electric motorcycle, bears most of the vehicle's load and has a decisive influence on the overall structural strength and riding experience. The overall structural strength of the frame largely determines the safety performance of the electric motorcycle.

[0003] Existing electric motorcycle frames generally increase structural strength by increasing the amount of steel. This method greatly increases the weight of the electric motorcycle frame, which reduces the overall performance of the electric motorcycle and affects normal riding.

[0004] Therefore, we propose an electric motorcycle frame that can mount a front wheel steering column and limit the maximum steering angle of the front wheel to ensure the safety of the electric motorcycle. It can form a support structure, saving frame materials and ensuring structural strength. It can also form a bending structure to facilitate the protection of the battery and motor. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an electric motorcycle frame. The technical problem this utility model aims to solve is: how to achieve a lightweight electric motorcycle frame while maintaining structural strength and stability, and ensuring safe use.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An electric motorcycle frame includes a front mounting mechanism, an inner support beam mechanism, two symmetrically arranged support bends on the front mounting mechanism, both of which are located below the support beam mechanism, two symmetrically arranged rear frame mechanisms on the front mounting mechanism, the two support bends being connected to the two rear frame mechanisms respectively, a motor fixing mechanism between the two rear frame mechanisms, and a battery rack mechanism between the ends of the two rear frame mechanisms, the battery rack mechanism being located below the motor fixing mechanism.

[0008] The working principle of this utility model is as follows: The front wheel steering column is installed and fixed through the front mounting mechanism, and the maximum steering angle of the front wheel steering column is limited. The main frame of the electric motorcycle is composed of the front mounting mechanism, the support beam mechanism, the battery rack mechanism, two support bends, and two rear frame mechanisms. The overall rigidity of the frame is strengthened by the support beam mechanism and the two support bends, which improves the stability and handling of the vehicle and makes the vehicle lighter. The bending design of the rear frame mechanism ensures structural strength and saves materials. The drive motor and sprocket are fixed by the motor fixing mechanism, which facilitates the connection with the rear suspension wheel. The space formed by the bending part of the two rear frame mechanisms is convenient for installing battery components and motor.

[0009] The front mounting mechanism includes a front fork mounting base. From top to bottom, the front fork mounting base is provided with a main beam, a connecting beam, and a steering limit block. The main beam and the connecting beam are arranged in parallel. A reinforcing rib is provided between the connecting beam and the main beam. The end of the main beam is provided with two shock absorber suspension seats arranged symmetrically on the left and right. The connecting beam is provided with two fixing seats arranged symmetrically on the left and right.

[0010] With the above structure, the front fork mounting bracket is used to install the front wheel steering column, the fixed bracket is used to install the front wheel steering column, the steering limit block is used to limit the front wheel steering column and control the maximum steering angle of the front wheel, the reinforcing rib is used to strengthen the fixing effect between the connecting beam and the main beam, and the shock absorber suspension bracket is used to suspend and install the rear wheel shock absorber.

[0011] The support beam mechanism includes a support beam, which is fixed between the upper end of the connecting beam and the main beam. A fixing plate is fixed below the support beam, and a hinge seat one and a hinge seat two are respectively provided on both sides of the fixing plate.

[0012] With the above structure, the support beam, together with the reinforcing ribs, forms a support structure with the connecting beam and the main beam, strengthening the strength between the connecting beam and the main beam. The support beam, together with the two support bends, forms a triangular support structure with the two rear frame mechanisms to ensure structural strength. Hinge seat 2 and hinge seat 1 are used to fix other motorcycle components.

[0013] The rear frame mechanism includes a rear fork beam and a curved beam. The ends of the rear fork beams are fixedly connected to the side of the connecting beam, and the included angle between the axes of the two rear fork beams is 60°. The curved beam has a J-shaped structure. The inner ring of the curved beam is provided with a second fixed seat and a rear wheel suspension seat. The second fixed seat is located above the rear wheel suspension seat. The outer ring of the curved beam is provided with a seat mounting seat and a foot mounting seat.

[0014] With the above structure, the rear fork beam, the support bend on the same side, and the support beam form a triangular support structure, which strengthens the structural strength and ensures the structural stability. The bending design of the bend beam can save materials while ensuring structural strength, making the entire frame lighter. Two symmetrically arranged rear wheel suspension mounts are used to install the rear wheel axle, the outrigger mounts are used to fix the electric motorcycle outriggers and provide support for the electric motorcycle, two seat mounts are used to install the seat, and two mounting brackets are used to fix the controller.

[0015] One end of the damping bend is fixed to the main beam, and the other end of the damping bend is fixed to the curved beam on the same side, with the included angle between the two ends of the damping bend being 150°.

[0016] Using the above structure, the damping bend connects the main beam and the curved beam through a bending design, thereby providing support and strengthening the structure.

[0017] The motor fixing mechanism includes a shock-absorbing bend, which is straight in the middle and bent at both ends towards the middle at a fixed angle. The two ends of the shock-absorbing bend are respectively fixed between the curved beams of the two rear frame mechanisms. The shock-absorbing bend is provided with two symmetrically arranged motor mounting seats and a sprocket mounting seat. The axis of the sprocket mounting seat is perpendicular to the axis of the two motor mounting seats.

[0018] Using the above structure, the shock-absorbing bend is connected to the two side bends through a bending design. Two motor mounting brackets are used to fix the motor, and the sprocket mounting bracket is used to fix the sprocket, which facilitates connection with the rear suspension wheel.

[0019] The battery rack mechanism includes a connecting rod, which is fixedly installed between the curved beam end of the rear frame mechanism and the curved beam end of the second rear frame mechanism. A battery mounting seat is provided in the middle of the connecting rod, and foot pedals are fixed at both ends of the connecting rod.

[0020] With the above structure, the connecting rod is used to connect the two curved beams and provide a certain structural strength, the battery mounting bracket is used to fix the battery, and the foot pedal is used to install the rotating foot pedal.

[0021] Compared with existing technologies, this electric motorcycle frame has the following advantages:

[0022] 1. Install the front wheel steering column through the front mounting mechanism and limit the maximum steering angle of the front wheel to ensure the safety of electric motorcycle use.

[0023] 2. The front mounting mechanism and the support beam mechanism work together to form a support structure, ensuring the structural strength of the front part of the vehicle.
