Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, the scooter comprises a horizontally arranged bottom plate 1, two ends of the bottom plate 1 are respectively and rotatably connected with two front wheels 2 and a rear wheel 6, the two front wheels 2 are fixedly arranged at two ends of a connecting rod 7, a steering mechanism is fixedly arranged in the middle of the connecting rod 7, the steering mechanism realizes steering of the front wheels 2 through a steering rod 3, and a handle 4 is fixedly arranged at the upper end of the steering rod 3;

the steering mechanism comprises a sleeve 18, the sleeve 18 penetrates through the bottom plate 1 and is rotatably connected with the bottom plate 1, the lower end of the sleeve 18 is fixedly connected with the connecting rod 7, the upper end of the sleeve 18 is provided with an opening, the lower end of the steering rod 3 is inserted into the opening of the sleeve 18 and is rotatably connected with the sleeve 18, an adjusting rod 22 is further inserted into the side wall of the sleeve 18, which is close to the rear wheel 6, one end of the adjusting rod 22 penetrates through the side wall of the sleeve 18 and is inserted into a groove in the outer wall of the steering rod 3 for limiting the steering rod 3 to rotate relative to the sleeve 18, a sliding groove 20 is further formed in the side wall of the adjusting rod 22, and a third spring 21 for pressing the adjusting rod 22 to the steering rod 3 is arranged in the sliding groove 20.

Adjust pole 22 under the normal condition is pegged graft in the recess of dwang, and when rotating steering column 3, steering column 3 drives sleeve pipe 18, and sleeve pipe 18 drives connecting rod 7 and realizes turning to, and the user can also like whether will turning to take off and use according to individual selection in addition, need set up the following vice subassembly that turns to at the lower extreme of bottom plate 1 under this condition to realize turning to of scooter.

In addition, in order to improve the safety of the new hand when in use, the upper end of one side of the adjusting rod 22 far away from the sleeve 18 is also provided with a slot 23, the upper end of the bottom plate 1 is connected with a first pressing plate 15, one end of the first pressing plate 15 is hinged with the bottom plate 1, and a second spring 16 is arranged between the first pressure plate 15 and the bottom plate 1, the second spring 16 is sleeved on an inserted rod 17 fixed at the lower end of the first pressure plate 15, and the bottom plate 1 is provided with a through hole 24, the lower end of the inserted link 17 penetrates through the through hole 24, when in use, the first pressing plate 15 can be stepped on by feet, the second spring 16 is compressed, the first pressing plate 15 presses the inserted rod 17 into the slot 23, the rotation of the sleeve 18 is limited, thereby make the scooter along rectilinear motion, when needs adjust the direction, will step on the foot on first clamp plate 15 and loosen and can realize turning to of scooter through rotating steering column 3.

In order to avoid the scooter to make the new hand inconvenient control because of turning to too sensitively, at bottom plate 1 lower extreme with still be connected with reset assembly 8 between connecting rod 7, reset assembly 8 is two sets of and the symmetry is installed in the installation cavity 11 of bottom plate 1 lower extreme. Reset assembly 8 can produce the power that makes front wheel 2 return to positive after turning to, and turn to the big more big power that returns positive that the angle produced big more to make things convenient for the returning of scooter direction on the one hand, avoid appearing turning to the phenomenon that the car turned over fast and appearing on the one hand.

Specifically, the reset component 8 comprises a hinged shaft 14 and a limiting rod 12 fixedly connected with the hinged shaft 14, the hinged shaft 14 is hinged to the connecting rod 7, one end of the limiting rod 12 is inserted into a limiting groove 10 at the lower end of the bottom plate 1, a first spring 13 is further sleeved on the limiting rod 12, and the first spring 13 is located between the limiting groove 10 and the hinged shaft 14. When the scooter rotates to one direction, the limiting rod 12 of the direction moves towards the direction deep into the limiting groove 10, the first spring 13 on the side is compressed, the limiting rod 12 on the other side moves towards the direction far away from the limiting groove 10, in order to avoid the limiting rod 12 from separating from the limiting groove 10, it is required to ensure that when the scooter rotates to the maximum angle towards one side, the limiting rod 12 on the other side still does not completely separate from the limiting groove 10, so that the resetting of the limiting rod is facilitated, in addition, one side of the limiting rod 12 is hinged with the connecting rod 7 through the hinged shaft 14, so that the directions of the limiting rod 12 and the limiting groove 10 are always kept consistent, and the friction generated in the steering process is avoided.

In order to avoid causing the incident because of the steering column 3 is malfunctioning, in order to further improve the interest of scooter simultaneously, still include vice subassembly that turns to, vice subassembly that turns to is two sets of and the symmetry is installed in installation cavity 11 of bottom plate 1 lower extreme. The scooter turns to through vice subassembly that turns to.

Specifically, vice steering assembly includes vice steering column 93, vice steering column 93 one end with connecting rod 7 is articulated, vice steering column 93 other end with bottom plate 1 is articulated, vice steering column 93 middle part is articulated, just vice steering column 93 upwards outstanding and run through bottom plate 1, vice steering column 93 upper end still overlaps and is equipped with second clamp plate 25, second clamp plate 25 joint is in can be relative bottom plate 1 upper and lower displacement in the bottom plate 1 for adjust the horizontal distance at vice steering column 93 both ends. For example, when the scooter needs to be rotated to the right, the second pressing plate 25 on the left side is stepped down by a moving distance with a foot, and the horizontal distance between the two ends of the left auxiliary steering rod 93 is increased, so that the scooter is rotated to the right. For the technical scheme, when the scooter is in linear motion, the second pressing plate 25 is located at the middle position of the upper and lower displacement ranges of the scooter, when the scooter rotates rightwards, the auxiliary steering rod 93 on the right side protrudes upwards to drive the second pressing plate 25 to move upwards, when the scooter rotates rightwards to the maximum angle, the second pressing plate 25 just moves to the highest position, and the auxiliary steering rod 93 on the left side is driven by the second pressing plate 25 on the left side to move downwards to the lowest position, so that the problem that the rotation angle is influenced by the existence of the auxiliary steering rod 93 is avoided.

In order to facilitate the installation of the rotating rod, an opening in the sleeve penetrates through the sleeve, a sealing block is fixedly arranged at the lower end of the opening of the sleeve, and the sealing block is positioned at the lower end of the steering rod and is in clearance fit with the steering rod.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
