[0020] 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.
[0021] Please see Figures 1-4This utility model provides the following technical solution: an electric vehicle with an auxiliary limiting structure, including an electric vehicle body 1, a fixing block 2 connected to the bottom surface of the pedal of the electric vehicle body 1, a support frame 4 rotatably connected to the surface of the fixing block 2 via a rotating shaft 3, a trapezoidal groove 5 opened on the longitudinal end surface of the support frame 4, the surface of the trapezoidal groove 5 engaging with the surface of a limiting block 6, the surface of the limiting block 6 connected to the surface of a fixing plate 7, the surface of the fixing plate 7 connected to the side of the pedal of the electric vehicle body 1, a side block 8 connected to the bottom surface of the pedal of the electric vehicle body 1, a plug rod 9 movably inserted into the surface of the side block 8, the surface of the plug rod 9 transversely penetrating and inserting into a circular groove on the surface of the support frame 4, and the surface of the plug rod 9 connected to... A limiting plate 10 is connected to a spring 11. The other side of the spring 11 is connected to the adjusting groove inside the side block 8. The other side of the side block 8 abuts against the moving frame 12. The surface of the moving frame 12 is connected to the insert rod 9. The top surface of the longitudinal end of the moving frame 12 is slidably connected to the limiting strip 13. The surface of the limiting strip 13 is connected to the pedal surface of the electric vehicle body 1. In this design, the electric vehicle body 1 is the main body of the electric bicycle, and a large number of related components are set in the main body of the electric bicycle. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.
[0022] In use: The electric scooter uses a battery as its energy source, storing electrical energy. When the rider turns the throttle, the control system receives the signal, regulates the current output from the battery, and transmits it to the motor. The motor converts the electrical energy into mechanical energy, driving the wheels to rotate, thus propelling the vehicle forward. Simultaneously, safety devices such as the braking system convert kinetic energy into heat when the rider operates the scooter, dissipating it to slow down or stop the vehicle. Furthermore, auxiliary functions such as lights and the instrument panel are also powered by the battery, providing functions such as illumination and displaying vehicle status.
[0023] Preferably, a circular through groove is longitudinally opened on the transverse end surface of the support frame 4, the shape and size of which are adapted to the insertion rod 9, and trapezoidal grooves 5 are symmetrically opened on the inner walls of the longitudinal ends of both sides of the support frame 4, and the shape and size of the trapezoidal grooves 5 are adapted to the limiting block 6.
[0024] In practical use, the insertion rod 9 is inserted into the circular groove at the intersection of the side block 8 and the support frame 4, fixing the rotating and retractable support frame 4 at the bottom of the pedal of the electric vehicle body 1, so as to avoid affecting the normal movement of the electric vehicle body 1.
[0025] Preferably, the fixed block 2, the rotating shaft 3, and the support frame 4 form a rotating connection structure.
[0026] In practical use, when the support frame 4 is rotated 90° counterclockwise via the rotating shaft 3 connected on one side, the support frame 4 supporting the electric vehicle body 1 can be rotated and stored.
[0027] Preferably, a rectangular groove is formed on the surface of the side block 8, the shape and size of which are adapted to the lateral end of the support frame 4.
[0028] In practical use, when the support frame 4 is rotated 90° counterclockwise by the rotating shaft 3 connected on one side, until the support frame 4 abuts against the rectangular groove opened on the surface of the side block 8, the position of the support frame 4 stored on the side block 8 is fixed by inserting the elastically connected plug rod 9.
[0029] Preferably, the side block 8, the insertion rod 9, the limiting plate 10 and the spring 11 form an elastic connection structure.
[0030] In practical use, the insertion rod 9 connected to one side of the movable frame 12 and the limiting plate 10 connected to it move in the adjustment groove on the surface of the side block 8. The elastic spring 11 causes the insertion rod 9 to spring back and reset, so that the insertion rod 9 is inserted into the circular groove at the intersection of the surface of the side block 8 and the support frame 4, fixing the rotating and retractable support frame 4 at the bottom of the pedal of the electric vehicle body 1. In actual use, the spring 11 can be made of 65Mn spring steel. 65Mn spring steel has good strength, elasticity and fatigue resistance, and can maintain its performance in repeated compression and rebound, adapting to the frequent operation of the insertion rod 9.
[0031] Preferably, the movable frame 12 has a U-shaped integrated structure, with a semi-circular through groove on the inner wall surface of its longitudinal end, and the shape and size of the semi-circular through groove are adapted to the limiting strip 13.
[0032] In practical use, the movable frame 12 is fitted onto the bottom pedal surface of the electric vehicle body 1, and slides on the limiting strip 13 through the semi-circular through groove on it, so that the movable frame 12 can be stably moved on the surface of the electric vehicle body 1, thereby driving the insertion rod 9 to move.
[0033] Working principle: When using the electric vehicle 1 for commuting or movement, the user stands on the pedal of the electric vehicle 1 and starts the motor by turning the handle, which drives the wheels to rotate. During operation, when stopping is required, the user can dismount and stand beside the electric vehicle 1, then pull the moving frame 12 backward on the limit strip 13. This moves the insert rod 9 connected to one side of the moving frame 12 within the adjustment groove on the inner wall of the side block 8 until the insert rod 9, inserted into the circular groove at the intersection of the fixed plate 7 and the support frame 4, disengages from the support frame 4. This allows the support frame 4, fixed to the side block 8, to fall downward under gravity. When the support frame 4 falls, the part connected to it via the rotating shaft 3 on one side can... The support frame 4 is rotated downwards by 90° until the support foot at the bottom of the support frame 4 touches the ground to support and limit the electric vehicle body 1. At the same time, when the support frame 4 rotates downwards, the trapezoidal groove 5 on its surface can fit onto the surface of the limiting block 6. In use, the limiting block 6 can be made of wear-resistant and anti-aging nitrile rubber or polyurethane material, and can be used with industrial-grade structural adhesive (such as epoxy resin) to improve adhesion and durability. At this time, the barbed structure on the surface of the trapezoidal limiting block 6 and the trapezoidal groove 5 with rough inner wall are engaged and fixed together, thereby fixing the position of the support frame 4 after the rotation angle has been adjusted, so that it can stably support the stopped electric vehicle body 1, support and limit the stopped electric vehicle body 1, and prevent it from tilting or even falling over, which would cause damage to the vehicle body.
[0034] Before restarting the electric vehicle body 1, pull the support frame 4 backward again to disengage it from the locking block 6, thereby rotating and adjusting the longitudinally fixed support frame 4. When the support frame 4 rotates 90° counterclockwise via the rotating shaft 3 connected on one side, until the support frame 4 abuts against the rectangular groove on the surface of the side block 8, pull the moving frame 12 to move it to the right on the limiting strip 13. This causes the moving frame 12 to disengage the connected insertion rod 9 from the circular groove on one side of the inserted side block 8. When the support frame... 4. After rotating and inserting the transverse end into the groove on the surface of the side block 8, release the rightward pulling of the moving frame 12. The insertion rod 9 connected to one side of the moving frame 12 and the limiting plate 10 connected to it move in the adjustment groove on the surface of the side block 8. The elastic connection of the spring 11 causes the insertion rod 9 to spring back to its original position, so that the insertion rod 9 is inserted into the circular groove at the intersection of the surface of the side block 8 and the support frame 4, fixing the rotating and retracted support frame 4 at the bottom of the pedal of the electric vehicle body 1, so as to avoid affecting the normal movement of the electric vehicle body 1.
[0035] The above-mentioned components can be made of stainless steel, which is corrosion-resistant and has high strength. It can withstand the water vapor, dust and other environments that electric vehicle bodies use daily, and is not easy to rust or be damaged, ensuring the reliability of mechanical structure connection and limit.
[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
