Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle technology, specifically to an anti-tipping electric vehicle. Background Technology
[0002] Electric vehicles, also known as "electric bikes," are pure electric motor vehicles powered by batteries and driven by electric motors (DC, AC, series, or separately excited). Electric vehicles are mainly categorized into electric bicycles, electric motorcycles, electric balance scooters, electric skateboards, and electric tricycles. These different types vary significantly in terms of functionality, range, and target audience. Some electric vehicles are designed with folding frames for greater portability, significantly reducing the space they occupy when folded.
[0003] Traditional electric vehicles use a rigid frame structure, which cannot effectively decompose inertial centrifugal force when turning. This results in lateral force acting entirely on one wheel. Furthermore, the linkage between the vehicle body and the steering system is too strong, causing the vehicle's posture adjustment to lag behind the steering action when turning, which exacerbates the risk of center of gravity shift and makes the performance unsatisfactory.
[0004] Therefore, we propose an anti-tipping electric vehicle to solve the above problems. Summary of the Invention

[0010] Furthermore, the connecting hole and the swing adjustment hole are located at the longitudinal centerline of the rear section of the vehicle body, and the swing adjustment hole is arc-shaped and located directly above the connecting hole.
[0011] Furthermore, the rear section of the vehicle body is provided with oblique holes at both ends, which are respectively opposite to the two ends of the swing adjustment hole, and the swing adjustment component is installed inside the oblique holes.
[0012] Furthermore, the swing adjustment component includes an adjustment screw threaded into the oblique hole, a spring movably disposed at one end of the adjustment screw, and a plastic plug disposed at the end of the spring away from the adjustment screw.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0030] like Figure 1-6 As shown in the figure, an anti-rollover electric vehicle according to one embodiment of the present invention includes a front section 1 and a rear section 2. One end of the front section 1 is provided with a rotating shaft 11 and a limiting shaft 12. The interior of the rear section 2 is provided with a connecting hole 21 and a swing adjustment hole 22 that are respectively fitted to the rotating shaft 11 and the limiting shaft 12. Both ends of the rear section 2 are provided with a swing adjustment component 3 that extends into the swing adjustment hole 22 and abuts against the surface of the limiting shaft 12. Through the rotational connection design of the front section 1 and the rear section 2, the inertial force during turning is dynamically decomposed, reducing the risk of rollover, while maintaining the integrity of the vehicle body.
[0031] like Figure 6As shown, in some embodiments, the connecting hole 21 and the swing adjustment hole 22 are located at the longitudinal centerline of the rear section 2 of the vehicle body, and the swing adjustment hole 22 is arc-shaped and located directly above the connecting hole 21.
[0032] The front section 1 of the vehicle body swings relative to the rear section 2 of the vehicle body around the rotation axis 11, and the swing amplitude is controlled by the limiting axis 12. The maximum distance of the swing amplitude is the distance between the two ends of the swing amplitude adjustment hole 22. The vertical layout of the arc-shaped swing amplitude adjustment hole 22 and the connecting hole 21 ensures that the swing torque is transmitted evenly and avoids local stress concentration that could lead to structural deformation.
[0033] like Figure 6 As shown, in some embodiments, the rear section 2 of the vehicle body is provided with oblique holes 23 at both ends, which are respectively opposite to the two ends of the swing adjustment hole 22. The swing adjustment component 3 is installed inside the oblique hole 23. The swing adjustment component 3 includes an adjustment screw 31 threaded into the oblique hole 23. A spring 32 is movably provided at one end of the adjustment screw 31. A plastic plug 33 is provided at the end of the spring 32 away from the adjustment screw 31. The end of the plastic plug 33 away from the spring 32 abuts against the surface of the limiting shaft 12. An internal hexagonal hole 35 is provided at one end of the adjustment screw 31. A silicone decorative component 34 located at one end of the adjustment screw 31 is also provided inside the oblique hole 23.
[0034] The oblique hole 23 and the swing adjustment hole 22 form a complementary angle, expanding the contact area of the limiting shaft 12 and improving the stability and buffering effect during the swing process. The adjustable damping system composed of the oblique hole 23 and the swing adjustment component 3 achieves two-stage shock absorption through the composite buffer structure of spring 32 and plastic plug 33. In the initial stage, the plastic plug 33 absorbs the instantaneous impact, and in the middle stage, the energy is released through the energy stored by spring 32. The combination of spring 32 and plastic plug 33 provides adjustable damping force, reduces friction noise of metal parts, and extends service life. The silicone decorative part 34 hides the internal hexagonal hole. 35. Balancing ease of operation and aesthetic appeal, and meeting the personalized needs of consumers, the silicone decorative part 34 can be removed during use. Then, the adjusting screw 31 can be rotated through the internal hex wrench via the internal hex hole 35 to control the amplitude of the compression of the spring 32 by the adjusting screw 31, and to control the rebound space of the spring 32. This limits the amplitude of the compression of the spring 32 by the limit shaft 12 against the plastic plug 33, thereby adjusting the swing amplitude of the front section 1 of the vehicle body relative to the rear section 2 of the vehicle body. Consumers can adjust the degree of rotation and swing by adjusting the adjusting screw 31 according to their own experience.
[0035] like Figure 4 As shown, in some embodiments, a support member 13 is fixedly installed inside one end of the front section 1 of the vehicle body, and both ends of the rotating shaft 11 and the limiting shaft 12 are inserted into the two sides of the support member 13 and are equipped with locking screws 14.
[0036] The support member 13 is fixed inside one end of the front section 1 of the vehicle body and swings synchronously with the front section 1 of the vehicle body. The locking screws 14 are installed at both ends of the support member 13 to lock the rotating shaft 11 and the limiting shaft 12. The support member 13 and the locking screws 14 double fix the rotating shaft 11 and the limiting shaft 12 to prevent axial loosening caused by high-frequency swing and improve safety redundancy.
[0037] like Figure 1-3 As shown, in some embodiments, a seat 4 is also included, and the bottom of the seat 4 is provided with connecting seats 41 extending to both sides of the rear section 2 of the vehicle body. The connecting seats 41 are fixedly connected to the rear section 2 of the vehicle body by locking screws 42.
[0038] The locking screw 42 improves the connection stability between the seat 4 and the rear section 2 of the vehicle body. The relative position of the seat 4 and the rear section 2 of the vehicle body is fixed and does not swing with the front section 1 of the vehicle body. The locking screw 42 and the locking screw 14 are also provided with an internal hexagon hole 35 at one end, which can be disassembled and assembled with an internal hexagon wrench, making it more convenient to use.
[0039] like Figure 2 As shown, in some embodiments, a steering column 15 is movably provided at the end of the front section 1 of the vehicle body away from the rear section 2 of the vehicle body. A front wheel 16 is provided at the bottom of the steering column 15, and a handle 17 is provided at the top of the steering column 15. Rear forks 24 are provided inside both sides of the rear section 2 of the vehicle body. A rear wheel 25 is provided at the end of the rear fork 24 away from the rear section 2 of the vehicle body, and a hub motor 26 is provided inside the rear wheel 25.
[0040] The handlebar 17 is a common type of electric vehicle handlebar with Hall effect control, which can control the speed at which the hub motor 26 drives the rear wheel 25 to rotate. The front section 1 of the vehicle body, the steering column 15, and the rear fork arm 24 are all designed to be foldable, which takes up less space when folded and makes them more convenient to carry.
[0041] like Figure 1-2 As shown, in some embodiments, a battery pack 18 is provided at one end of the front section 1 of the vehicle body, and a foot pedal 19 is provided at the bottom of the other end.
[0042] The battery pack 18 is electrically connected to the hub motor 26 and the Hall effect throttle, providing power to the hub motor 26. The user can control the hub motor 26 to drive the rear wheel 25 to rotate by turning the Hall effect throttle. The pedal 19 adopts a foldable design, which makes it convenient for the user to rest their feet. It can be folded up when not in use.
[0043] In summary, dynamic force dissipation is achieved through a split frame structure. The front section 1 and rear section 2 of the frame are connected by a rotating shaft 11 to form a swing mechanism. When turning, the inertial centrifugal force is automatically decomposed, significantly improving riding stability and reducing the risk of rollover. The arc-shaped swing amplitude adjustment hole 22 and the limiting shaft 12 work together to control the swing amplitude. With the swing amplitude adjustment component 3 inside the inclined hole 23, two-stage buffering and shock absorption are achieved, which absorbs instantaneous impact and reduces metal friction noise. Users can adjust the swing damping intensity themselves through the hidden adjustment screw 31 to meet personalized control needs. The foldable frame and the seat 4 fixed by the locking screw 42 optimize space utilization and riding comfort while ensuring structural safety, achieving a dual improvement in safety protection and user customization.
