[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 7 ,

[0025] An electric racing vehicle comprises a frame 1, on which a wheel device 2, a driving device 3 and a braking device 4 are arranged, wherein the driving device 3 comprises a lithium battery pack and a motor, and the motor is provided with a power sprocket, and the wheel device 2 comprises a front wheel and a rear wheel, wherein the front wheel is rotatably arranged on the frame 1, and the rear wheel comprises a wheel hub 21 and a wheel rim 23, wherein the wheel hub 21 is rotatably arranged on the frame 1 and is provided with a sprocket 22, wherein the sprocket 22 is connected to the power sprocket by a chain, and the rotation of the motor can drive the wheel hub 21 to rotate.

[0026] The wheel rim 23 is rotatably arranged on the outer ring of the wheel hub 21, and the two can rotate independently of each other. A plurality of sliding cavities are evenly opened on the outer ring of the wheel hub 21, and a locking member 24 is slidably arranged in the sliding cavity. A fifth elastic member 241 is sleeved on the locking member 24, and two ends of the fifth elastic member 241 respectively touch the limiting members at the rear end of the locking member 24, and the other end touches the upper end surface of the sliding cavity.

[0027] A plurality of grooves 234 are evenly provided on the inner wall of the wheel rim 23, and the number of the grooves 234 is a multiple of the sliding cavity, so that when one of the locking pieces 24 is aligned with the groove 234, it and the locking piece 24 are simultaneously aligned with the groove 234 at the corresponding position. When electric drive is not used, the wheel hub 21 does not rotate, and the human foot acts on the bottom surface to move the vehicle forward, and the wheel rim 23 and the wheel hub 21 rotate relative to each other. When a motor is used for drive, the wheel hub 21 rotates, and the locking piece 24 slides outward under the action of centrifugal force, thereby falling into the corresponding groove 234, so that the wheel hub 21 and the wheel rim 23 are connected as a whole, thereby driving the wheel rim 23 to rotate, thereby driving the vehicle to move forward.

[0028] The two side walls of the wheel rim 23 are inclined walls, and a plurality of cavities 231 are evenly opened in the inclined walls on both sides, and a first magnetic block 232 is slidably arranged in the cavity 231, and the outer circle of the sliding direction points to the center of the circle, and a first elastic member 233 is arranged on the end face of the first magnetic block 232 away from the center of the circle, and the other end touches the upper end face of the cavity 231, so that when the wheel rim 23 does not rotate, the first magnetic block 232 touches the lower end of the cavity 231, which is closest to the center of the circle at this time.

[0029] The brake device 4 includes a sliding block 41 and a sliding frame 42. The sliding frame 42 is symmetrically arranged on the frame 1 and is respectively located on both sides of the wheel rim 23. The sliding block 41 is elastically slidably arranged on the sliding frame 42, and a second magnetic block 411 is arranged on the sliding block 41. The second magnetic block 411 is magnetically attracted to the first magnetic block 232. A second elastic member 421 is also arranged on the sliding frame 42, and its two ends are respectively arranged on the sliding block 41 and the sliding frame 42. A bevel friction plate 412 is arranged on the sliding block 41.

[0030] When in a stationary state, the first magnetic block 232 is in contact with the lower end surface of the cavity 231 under the action of the first elastic member 233, and the sliding block 41 is connected to the first magnetic block 232 by magnetic force. At this time, the sliding block 41 is not in contact with the wheel rim 23. When the vehicle starts to move, the first magnetic block 232 overcomes the elastic force of the first elastic member 233 under the action of centrifugal force and slides upward, causing the first elastic member 233 to deform, thereby driving the sliding block 41 to slide upward together. At this time, the faster the speed of the wheel rim 23, the greater the centrifugal force applied to the first magnetic block 232, and the greater the deformation of the first elastic member 233. When the vehicle speed reaches a certain level, that is, the centrifugal force generated by the first magnetic block 232 causes the inclined friction plate 412 on the sliding block 41 to contact the inclined walls on both sides of the wheel rim 23, the inclined friction plate 412 rubs against the wheel rim 23, thereby reducing the speed of the wheel rim 23.

[0031] This ensures that when the vehicle is going too fast, the brakes can be automatically intervened to slow down the vehicle, and when the speed drops, the brakes can be automatically disengaged so that the vehicle speed does not exceed a set value.

[0032] The frame 1 is provided with an elastic inflatable cavity 11 and a piston cavity 12, and a piston sliding block 121 is provided in the piston cavity 12, and the front end of the piston cavity 12 is connected with the elastic inflatable cavity 11. The piston sliding block 121 slides forward to press the gas in the piston cavity 12 into the elastic inflatable cavity 11, so that the elastic inflatable cavity 11 expands and extends upward to form a protective cushion, and the front end of the piston sliding block 121 is in contact with a third elastic member 122, and the other end is in contact with the front end of the piston cavity 12, and the rear end of the piston sliding block 121 is provided with one end of a pull rope 123, and the other end is connected to the sliding block 41, and a locking groove 124 is provided on the bottom surface of the piston cavity 12, and a third magnetic block 13 is provided below the front end of the piston cavity 12 for horizontal sliding, and the third magnetic block 13 is in contact with a sixth elastic member 132. The third magnetic block 13 is provided with a pulling member 131 on one end thereof which is in contact with the sixth elastic member 132. The pulling member 131 is extended outward and is located on the outer end of the frame 1. The pulling member 131 may be a pull rope or a pull rod. A latch cavity 1211 is provided in the piston sliding block 121. A latch member 125 is slidably provided in the latch cavity 1211. A protrusion 1251 is provided on the upper end of the latch member 125. A fourth elastic member 126 is sleeved on the latch member 125. Both ends thereof are respectively in contact with the protrusion 1251 and the latch cavity 1211, so that the latch member 125 is located in the latch cavity 1211 in the initial state. When the latch member 125 is subjected to a downward adsorption force, the latch member 125 can slide downward and extend out of the latch cavity 1211 to act on the locking groove 124.

[0033] When the vehicle is driving normally, the piston sliding block 121 contacts the rear end of the piston cavity 12 under the action of the third elastic member 122. At this time, the elastic inflatable cavity 11 is in the initial state and does not protrude upward. When the vehicle performs emergency braking or collides with other objects, the vehicle stops suddenly and the piston sliding block 121 slides forward under the action of inertia. The piston sliding block 121 slides forward to press the gas in the piston cavity 12 into the elastic inflatable cavity 11, so that the elastic inflatable cavity 11 expands and deforms and extends upward to form a protective pad. At this time, the human body also leans forward under the action of inertia, so that the human body touches the protective pad to protect the human body from injury.

[0034] When the speed is low, the inertia generated is small, and under the action of the third elastic member 122, the piston sliding block 121 will not move to the front end of the piston cavity 12. Therefore, after the vehicle stops, the piston sliding block 121 returns to its initial state under the action of the third elastic member 122. At this time, the gas in the elastic inflation cavity 11 returns to the piston cavity 12, and the elastic inflation cavity 11 returns to its initial state.

[0035] When the speed is fast, the inertia generated by sudden stop or collision is large, which causes greater damage to the human body and may also cause the human body to fall forward. Under the action of large inertia, the piston sliding block 121 can slide to the front end of the piston cavity 12. At this time, the third magnetic block 13 located at the front end of the piston cavity 12 absorbs the latch member 125 downward so that it touches the locking groove 124, thereby locking the piston sliding block 121 so that it will not slide backward when the vehicle stops and remain in the front end position. At this time, the elastic inflatable cavity 11 is in a state of expansion and deformation, extending upward to form a protective pad, thereby continuously protecting the human body from secondary injury.

[0036] When confirming that the human body is OK, the rider can pull the pulling member 131 to make the third magnetic block 13 leave under the latch member 125, so that the downward adsorption force of the latch member 125 disappears, and under the action of the fourth elastic member 126, it retracts upward into the piston sliding block 121, so that the piston sliding block 121 is unlocked and restored to its initial state backwards under the action of the third elastic member 122. At this time, the gas in the elastic inflatable cavity 11 returns to the piston cavity 12, and the elastic inflatable cavity 11 returns to its initial state.

[0037] Its working principle or usage is as follows:

[0038] When electric drive is not used, the wheel hub 21 does not rotate, and the human foot acts on the bottom surface to move the vehicle forward, and the wheel rim 23 and the wheel hub 21 rotate relative to each other. When the motor drive is used, the wheel hub 21 rotates, and the locking piece 24 slides outward under the action of centrifugal force, thereby falling into the corresponding groove 234, so that the wheel hub 21 and the wheel rim 23 are connected as a whole, thereby driving the wheel rim 23 to rotate, thereby driving the vehicle forward, thereby realizing the free switching between human sliding and electric drive.

[0039] When the vehicle starts to move, the first magnetic block 232 overcomes the elastic force of the first elastic member 233 under the action of centrifugal force and slides upward, causing the first elastic member 233 to deform, thereby driving the sliding block 41 to slide upward together. At this time, the faster the rotation speed of the wheel rim 23, the greater the centrifugal force applied to the first magnetic block 232, and the greater the deformation of the first elastic member 233. When the vehicle speed reaches a certain level, that is, the centrifugal force generated by the first magnetic block 232 causes the inclined friction plate 412 on the sliding block 41 to touch the inclined walls on both sides of the wheel rim 23, the inclined friction plate 412 rubs against the wheel rim 23, thereby reducing the rotation speed of the wheel rim 23, so that the vehicle can automatically control the vehicle speed when the vehicle speed exceeds the set value when it is driven by electricity or manpower.

[0040] When the vehicle is driving normally, the piston sliding block 121 contacts the rear end of the piston cavity 12 under the action of the third elastic member 122. When the vehicle stops suddenly or impacts, the piston sliding block 121 slides forward under the action of inertia. The piston sliding block 121 slides forward to press the gas in the piston cavity 12 into the elastic inflatable cavity 11, so that the elastic inflatable cavity 11 expands and deforms and extends upward to form a protective cushion. At this time, the human body also leans forward under the action of inertia, so that the human body touches the protective cushion to protect the human body from injury. At this time, the piston sliding block 121 slides to the piston cavity 12 under the action of greater inertia. 2, the third magnetic block 13 located below the front end of the piston cavity 12 attracts the latch member 125 downward, so that the latch member 125 touches the locking groove 124, thereby locking the piston sliding block 121, so that the piston sliding block 121 will not slide backward when the vehicle stops, and remain in the front position. At this time, the elastic inflatable cavity 11 continues to be in a protective pad state, thereby continuously protecting the human body from secondary injury. At the same time, during the process of the piston sliding block 121, the sliding block 41 is pulled upward by the pull rope 123 to slide, so that the vehicle is continuously in a braking state, further protecting the safety of the rider.

[0041] After confirming that the human body is OK, the rider pulls the pulling member 131 to make the third magnetic block 13 leave under the latch member 125, so that the downward adsorption force of the latch member 125 disappears, and under the action of the fourth elastic member 126, it retracts upward into the piston sliding block 121, thereby unlocking the piston sliding block 121, and allowing it to return to its initial state backwards under the action of the third elastic member 122. At this time, the gas in the elastic inflatable cavity 11 returns to the piston cavity 12, and the elastic inflatable cavity 11 returns to its initial state.
