Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiment in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and therefore the application is not limited to the specific embodiments disclosed below.

As shown in fig. 1 and 2, the scooter of one embodiment of the present application includes a footboard 30, a support bar 40, a left front wheel 11, a right front wheel 12, and a rear wheel 13. The left and right

front wheels

11 and 12 are disposed at the front portion 32 of the footboard 30, and the rear wheel 13 is disposed at the rear portion 34 of the footboard 30. The number of front wheels and rear wheels in this embodiment is merely an example.

The left front wheel 11 is connected to a left front wheel shaft 21, the right front wheel 12 is connected to a right front wheel shaft 22, the left front wheel shaft 21 and the right front wheel shaft 22 are connected by a link 23, and the left front wheel shaft 21 and the right front wheel shaft 22 are connected to the bottom of a front portion 32 of the footboard 30, respectively. The left front wheel 11 has a wheel pivot 111, the left front wheel 11 is connected to the left front wheel shaft 21 through the wheel pivot 111, the left front wheel 11 can be rotated with respect to the wheel pivot 111, and a bearing 112 and a bearing 113 are provided at the connection of the left front wheel 11 and the wheel pivot 111 to reduce the rotational friction coefficient. The connection structure of the right front wheel 12 and the right front axle 22 is the same as that of the left front wheel 11, and the description thereof is omitted.

Referring to fig. 2 and 3, the left front wheel axle 21 has a first pivot 211 and a first axis 212, while the left front wheel 11 and the left front wheel axle 21 can be steered with respect to the first pivot 211 and the first axis 212. The first axis 212 is inclined toward the front direction of the footboard 30 such that it forms a predetermined adjacent angle 214 with an upward axis 213 perpendicular to the footboard 30. The adjacent angle 214 is greater than 0 degrees and less than 90 degrees, preferably the adjacent angle 214 is 43 degrees, but the adjacent angle may be greater or less than the examples given herein. Accordingly, the right front wheel axle 22 has a second pivot 221 and a second axis 222, and the steering structure thereof is the same as that of the left front wheel axle 21, and the adjacent angle formed by the second pivot is the same as that of the left front wheel axle 21, and the description thereof is omitted.

The left front axle 21 may be connected to the bottom of the front portion 32 of the footboard 30 by a first pivot 211, and the right front axle 22 may be connected to the bottom of the front portion 32 of the footboard 30 by a second pivot 221. One end of the connecting rod 23 is connected with the left front wheel shaft 21 in a rotating matching mode, and the other end of the connecting rod 23 is connected with the right front wheel shaft 22 in a rotating matching mode.

Because of the adjacent angle, when a force is applied to the side of the left front axle 21, the left front axle 21 is steered to the left, and when the left front axle 21 is steered, the right front axle 22 can be steered to the same side by the connecting rod 23; when a force is applied to the right front wheel axle 22, the right front wheel axle 22 is steered to the right, and when the right front wheel axle 22 is steered, the left front wheel axle 21 is steered to the same side by the link 23. Therefore, when steering occurs, depending on the position of the link 23 connected to the left or right

front wheel axle

21 or 22, the link 23 moves left or right at the bottom of the front portion 32 of the footrest 30, and if the left front wheel axle 21 makes a left turn, the link 23 is pushed to steer the right front wheel axle 22, and the link 23 moves right, and if the left front wheel axle 22 makes a left turn, the link 23 is pulled to steer the right front wheel axle 22, and the link 23 moves left.

As shown in fig. 2 and 4, in this embodiment, a spring 50 is provided between the left and right

front axle

21, 22, the spring 50 being positioned to bias the left and right

front axle

21, 22 toward a position where the plane of symmetry of the link 23 overlaps with the plane of symmetry of the foot board 30. The spring 50 is operable between a released state and a deformed state. When the force is applied to steer the left front axle 21 or the right front axle 22, the spring 50 is steered from the released state to the deformed state, and when the applied force is released, the spring 50 returns to the released state. Thus, when a force is applied to steer the scooter, the link 23 moves left or right causing its plane of symmetry to be separated from the plane of symmetry of the footboard 30, and when the applied force is released, the left and right

front wheel shafts

21 and 22 will pivot to a position where the plane of symmetry of the link 23 overlaps the plane of symmetry of the footboard 30 due to the biasing action of the spring 50, i.e., self-righting is achieved. The symmetry plane of the footrest 30 is perpendicular to the link 23.

As shown in fig. 4 and 5, the link 23 has a catch 232 to which the spring 50 is mounted. As a non-limiting example, the spring 50 may be a compression spring, which may include a first deformation 502, a second deformation 504, and an arm 506 connected between the

deformations

502, 504, the first and

second deformations

502, 504 being substantially mirror-symmetrical with respect to a center line of the arm 506 in the released state. The flap 36 engaged with the bottom of the front portion 32 of the footboard 30 is disposed between the first deformation portion 502 and the second deformation portion 504 along the center line of the arm 506, thereby positioning the arm 506 at the intermediate position of the link 23 such that the respective one ends of the

deformation portions

502, 504 abut against one of the end walls 234 at both ends of the catching groove 232, and the respective other ends abut against one of the side surfaces of the flap 36. In this manner, when link 23 is moved to the left or right, one of the

deformations

502, 504 will be compressed between one side of flapper 36 and one of the end walls 234 to transition from the relaxed state to the deformed state. In other embodiments, the spring 50 may be an extension spring, and the deformation portion of the spring 50 may be extended when the link 23 moves left or right. The slot covers 60 are disposed at both ends of the slot 232 to prevent the spring 50 from being separated from the slot 232, and in the embodiment of the present invention, the number of the slot covers 60 is two, but the number of the slot covers 60 may be less than two or more than two.

The soft sleeve 70 fits over the spring 50 to prevent at least the

deformations

502, 504 of the spring 50 from contacting the

side walls

236, 238 of the catch 232. The

deformation portions

502 and 504 can rub against at least one of the

side walls

236 and 238 when the scooter turns from the released state to the deformed state, which is a main reason for generating abnormal noise during the turning of the scooter, the soft sleeve 70 is arranged so that the

deformation portions

502 and 504 only rub against the soft sleeve 70, and the soft sleeve 70 is soft, so that the abnormal noise generated by friction is greatly reduced. By way of non-limiting example, the soft sleeve 70 may be open at one end and closed at the other end so that the ends of the

deformations

502, 504 also do not contact the end wall 234 of the catch 232. In other embodiments, the soft sleeve 70 may be open at both ends. The number of the soft sleeves 70 may be set according to the form of the spring 50, such as the number of the deformation portions, in the embodiment of the present application, there are two soft sleeves 70, which are respectively sleeved on the

deformation portions

502, 504, but the number of the soft sleeves 70 may be less than two or more than two. The soft sleeve 70 may be made of any one of silicone, polyurethane, rubber, polyethylene, and nylon. In other embodiments, a soft layer may be disposed on the surface of the

side walls

236 and 238 of the slot 232, so that the

deformation portions

502 and 504 only contact with the soft layer and generate friction, the soft layer is usually firmly attached to the

side walls

236 and 238 of the slot 232, and of course, a soft layer may be disposed on the surface of the end wall 234, and the soft layer may be made of any one of silicone, polyurethane, rubber, polyethylene, and nylon.

The support bar 40 is held by the user as a handle for better balance, rather than for stiffening the scooter. Thus, the scooter may be operated with or without a support bar.

The embodiments described in this specification and the disclosure therein are provided by way of illustration only. The present application is equally applicable to other types of scooters.

While the present application has been described in detail with reference to the disclosed embodiments, various modifications within the scope of the present application will be apparent to those of ordinary skill in the art. It should be understood that features described with respect to one embodiment may generally be applied to other embodiments.
