Detailed Description

The invention will be further described with reference to specific embodiments below:

as shown in fig. 1-3, a shock absorbing mechanism of a scooter comprises a connecting frame 1 and wheels 2; the connecting frame 1 is used for connecting a vehicle main body; a wheel 2 is arranged below the connecting frame 1, and two sides of the wheel 2 are provided with guard plates 3; the backplate 3 has the depressed face for the inboard shaping, and its backplate frame 9 part is protruding to wheel 2 direction, and backplate 3 mainly protects wheel 2 to the depressed face that sets up on the backplate 3 both increased 3 intensity of backplate, bring certain aesthetic feeling for backplate 3 again.

Furthermore, the two side guard plates 3 are fixed through a rotating shaft 8, a resisting plate 6 is arranged in the middle of the rotating shaft 8, and torsion springs 5 are wound on the rotating shafts 8 at the two sides of the resisting plate 6; the rotation shaft 8 is divided into two areas by the resisting plate 6, and the torsion springs 5 are arranged in the two areas; the two torsion springs 5 are opposite in installation direction and same in size, one end of each torsion spring is connected with the guard plates 3 on two sides of the wheel 2, and the other end of each torsion spring is connected with the abutting plate 6.

Furthermore, the abutting plate 6 is provided with a through hole 13, and the rotating shaft 8 penetrates through the abutting plate 6 through the through hole 13 to fix the two side guard plates 3; in a normal state, the abutting plate 6 is located at the center of the rotating shaft 8.

Furthermore, a cover plate 7 is integrally formed on the abutting plate 6, and the cover plate 7 is bent into a right angle and covers the upper end and the front end of the rotating shaft 8; the connecting frame 1 and the wheel 2 are connected through the cover plate 7 and the abutting plate 6.

In the wheel driving state, the wheel 2 can rotate around the rotating shaft 8, but the wheel 2 is fixed through the vertical contact of the torsion spring 5; in a running state, when the wheel 2 bumps, the wheel 2 can vertically swing along the rotating shaft 8, and in the process of lifting, the torsion spring 5 is compressed by the brought impact force, the torsion spring 5 pulls back the wheel to the initial position through the torsion of the torsion spring 5, and meanwhile, the wheel 2 is driven to return to the initial position, so that the damping effect is achieved; compare in traditional 5 shock-absorbing structure of flexible torsional spring, the noise that 5 torsional springs brought is far less than the noise that 5 flexible torsional springs brought, has still increased apron 7 moreover, improves its noise reduction effect to the mounted position that 5 torsional springs located can not see in the normal use, makes whole vehicle more pleasing to the eye.

Moreover, the rotating shaft 8 is communicated with the left and right guard plates 3 and fixes the distance between the left and right guard plates; when the vehicle runs, one side of the wheel 2 bumps, the torsion spring 5 on one side is stressed preferentially, but the torsion spring 5 on the other side is driven to bear force in an auxiliary manner through the communicated rotating shaft 8, so that the stability of the vehicle is improved; meanwhile, when the vehicle is steered, the direction of the connecting frame 1 is required to be consistent with that of the wheel 2, but actually, the direction of the wheel 2 is slightly deviated from that of the connecting frame 1 due to inertia and friction; the utility model discloses in, when the vehicle turned to, when 2 directions of wheel and link 1's direction was skew, its axis of rotation 8 center can be skew slightly to support board 6, owing to set up the torsional spring 5 in the left and right sides this moment, through its big or small the same nature, pull back wheel 2 with link 1 parallel and level through its self torsion and length when skew to this skew of compensating the direction improves the stability when the vehicle turns to.

Furthermore, in the present embodiment, a plurality of first partition plates 10 are disposed on the two side guard plates 3, and a first fixing groove 11 is formed between the first partition plates 10; however, in this embodiment, the guard plate frame 9 is used to replace one of the partition plates, that is, the first partition plate 10 and the guard plate frame 9 form a first fixing groove 11, and the torsion spring 5 abuts against the guard plate frame 9 below the guard plate 3 and is limited and fixed by the first fixing groove 11; meanwhile, a second partition plate 16 is arranged at the abutting plate 6, but in consideration of the space problem at the abutting plate 6, in the embodiment, a screw is preferably adopted to replace the second partition plate 16, the screw is screwed on the abutting plate 6, a second fixing groove 12 is formed by the nut part and the cover plate 7, the other end of the torsion spring 5 abuts against the cover plate 7, and the limiting and fixing are performed through the second fixing groove 12; the torsion spring 5 is reinforced by the fixing groove, so that the fixing groove is more stable and durable; in addition, in the actual installation process, the installation is more convenient; in some embodiments, a rubber anti-slip sleeve or the like may be added to the head of the torsion spring 5, so as to prevent the torsion spring 5 from falling off and protect the portion of the torsion spring 5 abutted against; the fixing groove can be replaced by other fixing parts, such as fixing holes, bolts and the like.

In some embodiments, the damping mechanism is provided on both the front and rear wheels; in the damping mechanism of the front wheel, a user can steer the vehicle through the connecting frame 1; as shown in fig. 4, the shock absorbing mechanism in the rear wheel includes the left and right fender panels 3 of the wheel 2, a cover plate 7, a torsion spring 5, a resisting plate 6, a rotating shaft 8, and the like; the difference is that a mudguard 14 is further arranged on the wheel 2, the mudguard 14 is connected with the cover plate 7, and the other end of the torsion spring 5 is abutted against the mudguard 14.

Preferably, an abutment 15 integrally formed on the cover plate 7 is added to avoid damage to the fender 14 when the torsion spring 5 is moved.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
