Description

Technical Field

[0001] The utility model relates to the technical field of electric scooters, in particular to an electric scooter which is convenient for height adjustment. Background Art

[0002] An electric skateboard is a vehicle based on a traditional manual skateboard with an electric power kit added. Currently, electric skateboards are generally divided into two-wheel drive or single-wheel drive, and the most common transmission methods are hub motors and belt drives respectively. Its main power source is a lithium battery, which usually consists of components such as a pedal, wheels, a motor, a battery, a braking system, and a handle. It has the characteristics of being small and flexible and can be used in various scenarios such as urban streets, parks, and campuses.

[0003] In the prior art, due to the fixed body structure of the electric scooter, when the user rides the electric scooter, the space available for the user's feet to move on the vehicle body is small, which is not convenient for the user to stand and affects the user experience.

[0004] Currently, the Chinese utility model with the publication number: CN211139532U discloses an electric scooter with an adjustable body, including: a vehicle body, at the bottom of which there is a battery for supplying electric energy to the electric scooter; an operating rod, arranged at one end of the vehicle body and detachably connected to the vehicle body for controlling the movement of the vehicle body; a first wheel, arranged at one end of the vehicle body and rotatably connected to the operating rod for driving the vehicle body to move; a second wheel, arranged at the end of the vehicle body opposite to the first wheel and rotatably connected to the vehicle body for driving the vehicle body to move; an extension device, arranged on the vehicle body for adjusting the width of the vehicle body to increase the standing area of the user. The electric scooter is powered by the battery to drive the first wheel and the second wheel to rotate, thereby driving the vehicle body to move. Since the extension device plays an extension and widening role, it can widen the width of the vehicle body, increase the standing area of the user, facilitate the user to ride, and improve the user experience.

[0005] In view of the above problems, the prior patent has given a solution. During the process of the user riding the scooter, the existing electric scooter cannot perform effective shock absorption and buffering, so there will be a strong sense of bumpiness during riding. Long-term bumpiness is likely to cause fatigue in the user's hands and waist, and frequent vibrations are likely to cause loosening and damage of the components of the electric scooter, thus reducing the service life of the electric scooter, which is not conducive to the user's use. At the same time, when the user adjusts the height of the electric scooter, most use bolts for fixation. Therefore, each time the height is adjusted, the bolts need to be turned, which is relatively troublesome to adjust. At the same time, the threads of the bolts will be worn after long-term use, so the stability during riding is poor, thus not meeting the user's use requirements.

[0006] To this end, an electric scooter that is convenient for height adjustment is proposed. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0028] An electric scooter 1 that is convenient for height adjustment includes an electric scooter 1 body. A connecting rod 2 is provided on the front side of the electric scooter 1 body.

A connecting block 504 is bolted to the top of the buffer housing 501. The bottom of the connecting block 504 is rotatably connected to the top of the connecting shaft 3.

[0030] In this embodiment: By providing the electric scooter 1 body, connecting rod 2, connecting shaft 3, front moving wheel 4, buffer assembly 5, adjustment assembly 6, handle 7 and rear moving wheel 8, the user can adjust the handle 7 to a suitable height through the adjustment assembly 6. Therefore, when the user adjusts the height of the electric scooter 1, it is not necessary to use bolts for fixation. Thus, when the user adjusts the height of the electric scooter 1, there is no need to turn bolts, and the adjustment is relatively simple. At the same time, there will be no thread wear, avoiding poor stability during riding, so as to meet the user's usage requirements. During riding, by starting the electric scooter 1 body to drive the front moving wheel 4 and the rear moving wheel 8 to rotate, and then buffering through the buffer assembly 5 inside the connecting shaft 3 on the front side of the connecting rod 2, it can be realized that during the user's riding of the scooter, effective shock absorption and buffering can be carried out on the electric scooter 1. Therefore, there will be no strong bumping feeling during riding, thus reducing the fatigue of the user's hands and waist during long-term riding. Therefore, the components of the electric scooter 1 will not be loosened and damaged easily due to frequent vibrations, thereby increasing the service life of the electric scooter 1 and being beneficial to the user's use.

[0031] Specifically, as Figure 3 shown, the adjustment assembly 6 includes a housing 601. The housing 601 is bolted to the top of the connecting block 504. A rotating column 602 is bolted inside the housing 601. A driven gear 603 is rotatably connected to the top of the rotating column 602. A threaded rod 604 is bolted to the top of the driven gear 603. The threaded rod 604 is threadedly connected to an adjustment rod 605. The adjustment rod 605 is slidably connected inside the housing 601. A rotating rod 606 is rotatably connected to the outside of the housing 601. A driving gear 607 is bolted to the inside of the rotating rod 606. The driving gear 607 meshes with the driven gear 603.

[0032] Specifically, as Figure 4 shown, limiting grooves 9 are respectively formed inside the housing 601. Limiting blocks 10 are respectively bolted to the outside of the adjustment rod 605. The limiting blocks 10 are slidably connected inside the limiting grooves 9.

[0033] Specifically, as Figure 1 、 Figure 4 shown, a protective sleeve 11 is sleeved on the outside of the handle 7. Anti-slip patterns are formed on the surface of the protective sleeve 11.

[0034] In this embodiment: By providing a housing 601, a rotating column 602, a driven gear 603, a threaded rod 604, an adjusting rod 605, a rotating rod 606, a driving gear 607, a limiting groove 9, a limiting block 10, and a protective sleeve 11, when the user rotates the rotating rod 606 to drive the driving gear 607 to rotate, thereby driving the driven gear 603 at the top of the rotating column 602 inside the housing 601 to rotate, and then driving the adjusting rod 605 at the top of the threaded rod 604 to move up and down, it can be realized that when the user adjusts the height of the electric scooter 1, it is not necessary to use bolts for fixation. Therefore, when the user adjusts the height of the electric scooter 1, there is no need to turn the bolts, and the adjustment is relatively simple. At the same time, there will be no thread wear, avoiding poor stability during riding, thus meeting the user's usage requirements. By providing the limiting groove 9 and the limiting block 10, it can be realized that the adjusting rod 605 is limited during height adjustment to prevent deviation during the adjustment process. By providing the protective sleeve 11, it can be realized that the user's hand is protected during riding to prevent the hand from slipping during riding.

[0035] Specifically, as Figure 1 shown, connecting plates 12 are bolted to both sides of the connecting shaft 3, and the rear sides of the connecting plates 12 are bolted to the top of the electric scooter 1 body.

[0036] Specifically, as Figure 1 、 Figure 5 shown, an anti-slip pad 13 is adhered to the top of the electric scooter 1 body, and the anti-slip pad 13 is made of rubber material.

[0037] In this embodiment: By providing the connecting plates 12, it can assist in connecting the connecting rod 2 and improve the stability during riding. By providing the anti-slip pad 13, it can prevent the user's feet from slipping during riding.

[0038] Specifically, as Figure 1 shown, a support leg 14 is rotatably connected to the right side of the electric scooter 1 body in a damped manner, and the support leg 14 is made of stainless steel.

[0039] Specifically, as Figure 1 、 Figure 5 shown, a baffle 15 is bolted to the rear side of the electric scooter 1 body, and the baffle 15 is made of stainless steel.

[0040] In this embodiment: By providing the support leg 14, it can support the electric scooter 1. By providing the baffle 15, it can block rainwater and prevent it from splashing onto the user.

[0041] Working principle: During the user's ride on the scooter, the impact force generated by bumps is buffered by the buffer spring 503 inside the buffer groove 502 on the inner side of the buffer shell 501, and then limited by the connecting block 504. It can effectively shock-absorb and buffer the electric scooter 1 during the user's ride on the scooter, so there will be no strong bumpy feeling during the ride, thus reducing the fatigue of the user's hands and waist during long-term riding. Therefore, the components of the electric scooter 1 will not be easily loosened and damaged due to frequent vibrations, thereby increasing the service life of the electric scooter 1. Therefore, it is beneficial for the user to use. When adjusting the height of the electric scooter 1, the user rotates the rotating rod 606 to drive the driving gear 607 to rotate, thereby driving the driven gear 603 at the top of the rotating column 602 inside the outer shell 601 to rotate, and then driving the adjusting rod 605 at the top of the threaded rod 604 to perform lifting adjustment. It can be achieved that when the user adjusts the height of the electric scooter 1, bolts do not need to be used for fixation. Therefore, when the user adjusts the height of the electric scooter 1, there is no need to turn the bolts, and the adjustment is relatively simple. At the same time, there will be no thread wear, avoiding poor stability during the ride, so as to meet the user's usage requirements.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
