Technical Field

[0001] The present invention relates to the field of two-wheeled vehicles, in particular to a novel electric small-wheeled vehicle. Background Art

[0002] Two-wheeled electric vehicles are two-wheeled vehicles powered by onboard batteries. Driven by an electric motor, they are convenient and flexible, making them widely used for daily commuting. They are simple to operate and easy to charge, and their range varies depending on the model. Currently, the front and rear tires of two-wheeled electric vehicles are generally similar in size. The rear wheel acts as the driving wheel, providing power. At a constant speed, the larger the tire, the faster the vehicle can reach. The front wheel acts as the driven wheel, providing support and rolling action while also enhancing maneuverability.

[0003] The sizes of the front and rear wheels of two-wheeled electric vehicles in the prior art are almost the same. Although a larger front wheel can provide better passability, it will also cause a greater loss of space in the vehicle body. The front wheel serves as a driven wheel, and its upper part that does not intersect with the ground is useless. However, as part of the entire wheel, there is no way to remove it, which results in ineffective use of the space in the vehicle body. Summary of the Invention

[0017] 2. The present invention can fold the front of the vehicle and the handlebars into the two assembly frames through the folding handlebar mechanism. When folding the handlebars, it is only necessary to rotate the two handlebars downward and retract them into the mounting plate and the mounting surface. When unfolding, it is only necessary to pull the limit driving block upward, and the front of the vehicle only needs to be rotated downward to enter between the two assembly frames. Therefore, folding is convenient, which improves the convenience of folding the vehicle.

[0018] 3. The suspension mechanism of the present invention can reduce shock and provide an installation position. At the same time, only one suspension mechanism is needed. However, the current two-wheeled electric vehicles have two suspension mechanisms. Therefore, one suspension mechanism is reduced, but the function and effect are not changed, which can reduce costs.

The slider 408 can limit the movement trajectory under the limit of the slide groove 407, and the slider 408 is slidably connected to the inside of the slide groove 407. The bottom of the mounting plate 401 is fixedly connected to a rotating rod 409, and the top of the mounting plate 401 is provided with a mounting groove 410. The mounting groove 410 can provide an installation space, and a return spring 411 is provided inside the mounting groove 410. The interior of the mounting groove 410 is slidably connected with an inclined surface block 412, and the return spring 411 can provide the power for the inclined surface block 412 to reset.

The top of the rotating disk 415 is engaged with the sliding clamp 418.When the blocking block 403 is fully moved to the vertical surface of the inclined block 412, one of the folding handles 402 will not be rotated upward under the obstruction of the inclined block 412, so that the sliding bar 404 will not move downward, and then the folding state of the folding handle 402 can be maintained. At this time, the sliding block 412 on the lower side is moved to the left side. When the hole on the rotating disk 415 is rotated to the sliding clamp 418 on the upper side, the mounting plate 401 can be folded between the two assembly frames 1. When in use, the sliding clamp 418 is first released from the engagement with the rotating disk 415, and the mounting plate 401 is rotated upward, so that the mounting plate 401 can be unfolded. At this time, the limit driving block 413 is slid upward, thereby driving the inclined surface block 412 to move upward, and then the engagement of the inclined surface block 412 and the blocking block 403 can be released. Then, under the action of the elastic bar 406, the sliding bar 404 can be pulled downward, and then the two folding handles 402 can be rotated upward, so that the folding handles 402 can be unfolded.

[0036] The suspension mechanism 5 includes a fixed plate 501, which provides an installation position. The two sides of the fixed plate 501 are detachably connected to the inner sides of the two assembly frames 1. The bottom of the fixed plate 501 is rotatably connected to a resettable telescopic rod 502. A spring is installed inside the resettable telescopic rod 502 to play a vibration reduction role. Four rotating connecting rods 503 are rotatably connected between the two assembly frames 1. The rotating connecting rod 503 has a connecting function. A mounting sleeve 504 is rotatably connected between the four rotating connecting rods 503. The mounting sleeve 504 can provide a connecting function. The interior of the mounting sleeve 504 is rotatably connected to a rotating column 505. The rotating column 505 can rotate inside the mounting sleeve 504. The top of the rotating column 505 is rotatably connected to a rotating The limiting fork 506 is provided with a shock-absorbing spring 507 on the outer sleeve of the rotation limiting fork 506, and the rotation limiting fork 506 can provide a limiting effect. The outer sliding connection of the rotation limiting fork 506 is provided with a rotation sleeve 509, and the rotation sleeve 509 plays a connecting role. The outer rotation connection of the rotation sleeve 509 is provided with a connecting fork 508, and the connecting fork 508 has a connecting role. The connecting fork 508 is rotatably connected to the bottom of the rotating rod 409. The top end of the rotation limiting fork 506 is fixedly connected to the limiting plate 510, and the limiting plate 510 plays a limiting role to prevent the rotating sleeve 509 from sliding out of the range of the rotation limiting fork 506. The bottom of the rotating column 505 is fixedly connected to the mounting frame 511, and the mounting frame 511 can provide an installation position. The mounting frame 511 1 is rotatably connected to a plurality of rotating wheels 512 on the inner side, and the rotating wheels 512 can play the role of front wheels. A limit ring 513 is provided on the outer top of the rotating column 505, and the limit ring 513 has a limiting function. One end of the shock-absorbing spring 507 is fixedly connected to the bottom top of the rotating limit fork 506, and the other end of the shock-absorbing spring 507 is fixedly connected to the bottom of the rotating sleeve 509. When shock absorption is performed, the mounting sleeve 504 drives the rotating column 505 and the rotating limit fork 506 to move upward. Since the rotating sleeve 509 cannot move under the limitation of the connecting fork 508, the rotating sleeve 414 and the rotating rod 409, the rotating limit fork 506 can overcome the elastic force of the shock-absorbing spring 507 and move upward to cooperate with the rotating sleeve 5 09 compresses the shock-absorbing spring 507, uses the elastic force of the shock-absorbing spring 507 for buffering, and uses the rotating connecting rod 503 to connect the resettable telescopic rod 502, the assembly frame 1 and the mounting sleeve 504, and uses the resettable telescopic rod 502 for buffering again, and uses the rotating connecting rod 503 to maintain stability. When the mounting plate 401 is rotated, it can drive the rotating rod 409 and the connecting fork 508 to rotate, thereby driving the rotating sleeve 509 to rotate. Since the rotating limit fork 506 is square, the rotating sleeve 509 can drive the rotating limit fork 506 to rotate after rotating, and then drive the rotating column 505 to rotate, and drive the mounting frame 511 to rotate, so that steering can be performed, and the rotating wheel 512 can be used as the front wheel.

[0037] When the folding handle 402 is folded, the folding handle 402 is first rotated downward, so that the folding handle 402 can be rotated into the interior between the mounting plate 401 and the mounting surface 421. Since the folding handle 402 is rotated downward, the sliding bar 404 can be driven to move upward, thereby stretching the elastic bar 406, and when one of the folding handles 402 is rotated, it can drive the blocking block 403 to rotate upward. Since the inclined surface block 412 is an inclined surface, the blocking block 403 can be squeezed upward when it is rotated upward. When the blocking block 403 is completely moved to the vertical surface of the inclined surface block 412, one of the folding handles 402 can not be rotated upward under the obstruction of the inclined surface block 412, thereby preventing the sliding bar 404 from moving downward, and then the folding state of the folding handle 402 can be maintained. At this time, the sliding clamp 418 on the lower side is moved toward the connecting plate 4 When the cam 414 is in the state of being moved upward, the cam 415 is moved downward, and the cam 416 is moved downward, so that the cam 416 can be moved downward, and the cam 417 is moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward, and the cam 417 can be moved downward, so that the cam 417 can be moved downward,

[0038] When shock absorption is performed, the installation sleeve 504 drives the rotating column 505 and the rotating limit fork 506 to move upward. Since the rotating sleeve 509 cannot move under the limitation of the connecting fork 508, the rotating sleeve 414 and the rotating rod 409, the rotating limit fork 506 can overcome the elastic force of the shock-absorbing spring 507 and move upward, and then cooperate with the rotating sleeve 509 to compress the shock-absorbing spring 507, using the elastic force of the shock-absorbing spring 507 for buffering, and the rotating connecting rod 503 is used to connect the resettable telescopic rod 502, the assembly frame 1 and the installation sleeve 504. The resettable telescopic rod 502 is used for buffering again, and the rotating connecting rod 503 is used to maintain stability. When the mounting plate 401 is rotated, the rotating rod 409 and the connecting fork 508 can be driven to rotate, thereby driving the rotating sleeve 509 to rotate. Since the rotating limit fork 506 is square, the rotating sleeve 509 can drive the rotating limit fork 506 to rotate after rotating, and then drive the rotating column 505 to rotate, and drive the mounting frame 511 to rotate, so that steering can be achieved, and the rotating wheel 512 can be used as the front wheel.
