AI Technical Summary
The rear wheel shock absorbers of existing electric scooters tend to extend and retract frequently and significantly under high loads, which leads to a rapid decrease in shock absorption capacity and affects their service life.
Independent first and second shock absorbers are installed on both sides of the rear wheel of the electric scooter. The rear wheel connecting frame is formed by an integrally molded connecting plate and connecting rod, which are hinged to the main body of the frame to provide stable shock absorption performance.
It achieves left-right force balance of the rear wheel, reduces the impact of unilateral impact on the frame, extends service life, and maintains good shock absorption under high load.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric scooter technology, specifically to an electric scooter frame. Background Technology
[0002] With increasing urban traffic congestion and people's pursuit of convenient travel, electric scooters, as a new type of short-distance transportation tool, have gained popularity among consumers due to their compact size, flexibility, and ease of parking. Current electric scooters incorporate a shock absorber structure between the frame and the rear wheel fork to provide shock absorption for the rear wheel. However, because the rear wheel needs to provide power and bear weight, high loads cause the single shock absorber to frequently extend and retract significantly, resulting in a substantial decrease in shock absorption capacity after a short period of use. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an electric scooter frame that can provide stable shock absorption performance on both sides of the rear wheel, better balance the left and right forces on the rear wheel, extend service life, and meet high load requirements.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An electric scooter frame includes a frame body, a front wheel connecting frame fixedly mounted on the frame body, and a rear wheel connecting frame rotatably mounted on the frame body. The rear wheel connecting frame includes an integrally formed first connecting plate, a connecting rod, and a second connecting plate. A first shock absorber is disposed between the first connecting plate and the frame body, and a second shock absorber is disposed between the second connecting plate and the frame body. A battery compartment is provided inside the frame body, and a battery compartment cover is detachably mounted on the frame body.
[0006] As a further improvement to the above technical solution:
[0007] A seat cushion bracket is detachably mounted on the battery compartment cover.
[0008] The frame body is provided with an upper hinge seat and a lower hinge seat. The first connecting plate and the second connecting plate are provided with end hinge holes and a middle hinge hole. The first connecting plate and the second connecting plate are respectively hinged to the lower hinge seat through the end hinge holes. One end of the first shock absorber and the second shock absorber are respectively hinged to the upper hinge seat, and the other end of the first shock absorber and the second shock absorber are hinged to the middle hinge hole.
[0009] Compared with the prior art, the advantages of this utility model are:
[0010] The electric scooter frame of this utility model includes a frame body, and the rear wheel connecting frame of the frame body includes an integrally formed first connecting plate, a connecting rod, and a second connecting plate. A first shock absorber is provided between the first connecting plate and the frame body, and a second shock absorber is provided between the second connecting plate and the frame body. They work independently and can provide stable shock absorption performance on both sides of the rear wheel, better balance the left and right forces on the rear wheel, and reduce the impact of unilateral impact on the frame body. For example, the outer side of the rear wheel is subjected to greater pressure when cornering, which helps to extend the service life and can meet the needs of high-load applications. The shock absorption effect will not be significantly reduced during use. Attached Figure Description

Detailed Implementation
[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 and Figure 2As shown, the electric scooter frame of this embodiment includes a frame body 1, a front wheel connecting frame 2 fixedly mounted on the frame body 1, and a rear wheel connecting frame 3 rotatably mounted on the frame body 1. The rear wheel connecting frame 3 includes an integrally formed first connecting plate 301, a connecting rod 302, and a second connecting plate 303. A first shock absorber 4 is provided between the first connecting plate 301 and the frame body 1, and a second shock absorber 5 is provided between the second connecting plate 303 and the frame body 1. A battery compartment 101 is provided inside the frame body 1, and a battery compartment cover 102 is detachably mounted on the frame body 1. The electric scooter frame includes a frame body 1. The rear wheel connecting frame 3 of the frame body 1 includes an integrally formed first connecting plate 301, a connecting rod 302, and a second connecting plate 303. A first shock absorber 4 is installed between the first connecting plate 301 and the frame body 1, and a second shock absorber 5 is installed between the second connecting plate 303 and the frame body 1. These components work independently, providing stable shock absorption performance on both sides of the rear wheel, better balancing the lateral forces on the rear wheel, and reducing the impact of unilateral impacts on the frame body 1. For example, the outer side of the rear wheel experiences greater pressure when cornering, which helps extend its service life and meets the needs of high-load applications. The shock absorption effect does not significantly decrease during use. Specifically, a 5.5Ah battery can be installed in the battery compartment 101, making it lighter and suitable for lightweight models.
[0018] Preferably, a seat cushion bracket 6 is detachably installed on the battery compartment cover 102, allowing users to selectively install or remove the seat cushion, providing high flexibility and comfort.
[0019] like Figure 3 As shown, preferably, the frame body 1 is provided with an upper hinge seat 103 and a lower hinge seat 104. Both the first connecting plate 301 and the second connecting plate 303 are provided with end hinge holes 304 and middle hinge holes 305. The first connecting plate 301 and the second connecting plate 303 are respectively hinged to the lower hinge seat 104 through the end hinge holes 304. One end of the first shock absorber 4 and the second shock absorber 5 are respectively hinged to the upper hinge seat 103, and the other end of the first shock absorber 4 and the second shock absorber 5 are hinged to the middle hinge hole 305. In this embodiment, the frame body 1 is symmetrically provided with two sets of upper hinge seats 103 and two sets of lower hinge seats 104. Taking the first shock absorber 4 as an example, the frame body 1, the first shock absorber 4, and the first connecting plate 301 form a triangular support structure, which has the advantages of simple structure and convenient and quick installation and disassembly, and can provide stable shock absorption performance. The second shock absorber 5 is similar, and will not be described in detail here.
[0020] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
