[0026] like Figure 1-7As shown, a connection mechanism for preventing a three-wheel vehicle body from rolling over is provided, comprising: a fixing seat 1, the fixing seat 1 is welded to the vehicle body; a bearing assembly 2, the bearing assembly 2 is mounted on the fixing seat 1; a steering shaft 3, the first end of the steering shaft extends to be connected to the bearing assembly 2, and the steering shaft can rotate relative to the bearing assembly 2; a limiting assembly 4, the limiting assembly 4 is mounted on the steering shaft 3; an elastic member 5, the elastic member 5 is arranged between the limiting assembly 4 and the vehicle body, the first end of the elastic member 5 is connected to the limiting assembly 4, and the second end of the elastic member 5 is connected to the vehicle body; a rear wheel joint connecting seat 6, the second end of the steering shaft 3 is welded to the rear wheel joint connecting seat 6, and the rear wheel joint connecting seat 6 is used to connect the rear wheel of the vehicle; a shock absorber connecting seat 7, the shock absorber connecting seat is connected to the upper part of the rear wheel joint connecting seat 6, and the shock absorber connecting seat 7 is used to connect the rear wheel shock absorber of the vehicle.

[0027] In view of the technical problems described in the background art, since the body of the tricycles on the market is an integrated structure, the body of the tricycle is prone to tilt and overturn when the tricycle turns at a high speed or passes through an uneven road surface.

[0028] In this regard, a connection mechanism for preventing the three-wheel vehicle body from rolling over is provided. The connection mechanism is arranged between the vehicle body and the rear wheels, thereby realizing the segmented design of the front wheels and the rear wheels. Figure 3 As shown, the fixing seat 1 is welded to the vehicle body, the bearing assembly 2 is connected to the fixing seat 1 by screws, the limiting assembly 4 is connected to the steering shaft 3 by screws, the elastic member 5 is preferably in the form of a tension spring, and there are two tension springs, which are respectively arranged on both sides of the limiting assembly 4, and the tension springs respectively connect the limiting assembly 4 and the vehicle body, the rear wheel joint connection seat 6 is connected to the rear wheel, and the shock absorber connection seat is connected to the rear wheel. Through this structural design, the front wheel and the rear wheel of the tricycle can be connected in sections.

[0029] With the above structural design, when the tricycle turns at a high speed, the handlebar drives the body to turn, and the front and rear wheels are connected in sections. When turning, the body drives the bearing assembly 2 to rotate relative to the steering shaft 3, and will not cause the entire body to tilt. The rear wheels remain perpendicular to the ground and maintain grip, thereby avoiding the problem of body rollover; when the rear wheels pass through a road surface with asymmetric left and right heights, the rear wheels absorb the tilt through the rotation of the steering shaft 3, and the front and rear wheels will not tilt.

[0030] The connecting mechanism is used as an intermediate mechanism to connect the rear wheels and the body of the car. It cooperates with the suspension of the rear wheels to reduce the impact on the body of the car, improve the ground adhesion of the wheels, and improve the comfort of the car. The left and right wheels bounce independently and independently of each other, which can reduce the tilt and vibration of the body of the car; at the same time, it improves driving safety and ensures the personal safety of the driver.

[0031] refer to Figure 4-5 As shown, the utility model includes a reinforcement seat 8, the reinforcement seat 8 has a through hole, the steering shaft 3 passes through the through hole of the reinforcement seat 8, and the reinforcement seat 8 is fixedly connected to the rear wheel joint connection seat 6.

[0032] In order to improve the structural strength, a reinforcement seat 8 is added to support the steering shaft 3 .

[0033] like Figure 6 As shown, the fixing seat 1 is provided with a column 9 extending along the steering shaft 3, and the column 9 is used to cooperate with the limiting component 4 to limit the rotation angle of the steering shaft 3. The limiting component 4 is driven to rotate via the steering shaft 3, and the limiting component 4 contacts the column 9 to limit the rotation of the steering shaft 3.

[0034] Among them, the column 9 provided can be used with screws, and the number of screws used is two, and the screws are arranged at intervals. During use, such as passing over an uneven road surface, the rear wheel drives the steering shaft 3 to rotate, and the steering shaft 3 drives the limit assembly 4 to rotate. When it rotates to the maximum angle, the limit assembly 4 contacts the screw, limiting the limit assembly 4 from continuing to rotate, thereby limiting the maximum steering angle of the steering shaft 3.

[0035] Preferably, the limit assembly 4 and the column 9 limit the maximum steering angle of the steering shaft 3 to 40 degrees. Of course, other maximum steering angles can be selected according to implementation conditions, and there is no limitation on this.

[0036] like Figure 7 As shown, the limiting assembly 4 includes an upper cover 10 and a bottom plate 11 connected to the upper cover 10, and the upper cover 10 is connected to the steering shaft 3 through fasteners; when the limiting assembly 4 is driven to rotate by the steering shaft 3, the lower end surface of the bottom plate 11 contacts the column 9 for limiting.

[0037] In practice, the limit assembly 4 is composed of an upper cover 10 and a bottom plate 11. The upper cover 10 is fixedly connected to the steering shaft 3 by screws. The upper cover 10 is connected and fixed to the bottom plate 11 by screws. When the steering shaft 3 rotates, the limit assembly 4 is driven to rotate, and the bottom plate 11 contacts the column 9 to limit the maximum steering angle of the steering shaft 3.

[0038] Specifically, the bearing assembly 2 includes a bearing upper cover 12 , a bearing lower cover 13 and a bearing 14 . The bearing upper cover 12 is connected to the bearing lower cover 13 , and the bearing 14 is disposed between the bearing upper cover 12 and the bearing lower cover 13 .

[0040] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
