Description
Technical Field
The utility model relates to an electric bicycle or electric motorcycle accessory, in particular to a rocker arm device for a vehicle.
Background
Electric bicycle or electric motorcycle car mainly adopts the bumper shock attenuation of bumper shock absorber, and an effectual electric bicycle frame of shock attenuation like CN209553416U discloses, and it reduces the vibrations that support frame received in the motion through the shock attenuation pole (spring damper) of symmetry setting on braced frame. However, this kind of shock-absorbing structure is not good in the shock attenuation effect in the in-service use, because the compression volume of bumper shock absorber is all conducted to the seat, leads to beating more serious, and the travelling comfort is relatively poor.
Disclosure of utility model
In order to solve the problems of poor damping effect and large jumping, the utility model provides a rocker arm device for a vehicle, which comprises the following specific technical scheme:
a rocker arm apparatus for a vehicle, comprising a shock absorber, further comprising: the front frame is hinged with one end of the shock absorber; the connecting shaft is fixed on the front frame; the rear frame is rotatably arranged on the connecting shaft; the two ends of the rocker arm seat are respectively hinged with the shock absorber and the rear frame; the two ends of the rocker arm rod are respectively hinged with the rocker arm seat and the front frame; the shock absorber is located between the connecting shaft and the rocker arm seat.
The rocking arm seat reduces the swing angle of back frame through rotating, and then has reduced holistic jumping, has improved the travelling comfort of riding, and the shock attenuation effect is better simultaneously.
Preferably, the rocker arms are symmetrically arranged on two sides of the rocker arm seat.
The rocker arm rods symmetrically arranged are simple in structure and convenient to install.
Preferably, the rocker arm seat is provided with a rotating groove, and one end of the shock absorber is rotatably arranged in the rotating groove.
The rotary groove facilitates the installation of the shock absorber.
Preferably, an upper connecting column is arranged on the front frame and hinged with the shock absorber.
Preferably, a lower connecting column is arranged on the front frame and hinged with the rocker arm rod.
Preferably, a rear connecting column is arranged on the rear frame and hinged with the rocker arm seat.
Compared with the prior art, the utility model has the following beneficial effects:
the shock absorber of the vehicle rocker arm device provided by the utility model can buffer the compression stroke through the rocker arm seat, so that the jump during shock absorption is reduced, the comfort is improved, the whole structure is simpler, and the shock absorption effect is better.

Detailed Description
The utility model will now be further described with reference to the accompanying drawings.
As shown in fig. 1 to 6, a rocker arm apparatus for a vehicle includes a shock absorber 4, a front frame 1, a rear frame 2, a connecting shaft 3, a rocker arm seat 5, and a rocker arm lever 6.
As shown in fig. 1 to 4, the front frame 1 is rotatably connected with the rear frame 2 through a connecting shaft 3, the connecting shaft 3 is fixed at one side below the front frame 1, and one end of the rear frame 2 is rotatably connected with the connecting shaft 3 through a bearing. An upper connecting column 11 and a lower connecting column 12 are arranged on the front frame 1, and the upper connecting column 11 and the lower connecting column 12 are respectively positioned above and below the connecting shaft 3. One end of the damper 4 is hinged to the upper connecting post 11. The rear frame 2 is provided with a rear connecting column 21.
As shown in fig. 5 and 6, the rocker arm base 5 has a triangular shape, one end of which is provided with a rotation groove 51, and the third connection hole 53 at the other end of the rocker arm base 5 is rotatably connected with a third shaft 73 through a bearing, and the third shaft 73 is fixed on the rear connection post 21. The middle of the rocker arm seat 5 is provided with a second connecting hole 52, the second connecting hole 52 is rotationally connected with a second shaft 72 through a bearing, the second shaft 72 is fixed at one end of the rocker arm rod 6, and the rocker arm rod 6 is symmetrically arranged at two sides of the rocker arm seat 5. The rocker arms 6 which are symmetrically arranged are simple in structure and convenient to install. The bearing enables the rotation to be smoother.
The other end of the damper 4 is rotatably mounted in a rotation groove 51 of the rocker arm base 5.
The other end of the rocker arm 6 is rotatably mounted on the lower connecting post 12.
The swing angle of the rear frame 2 is reduced by rotating the rocker arm seat 5, so that integral jumping is reduced, riding comfort is improved, and meanwhile, the shock absorption effect is better.
The rocker arm 6 supports the rocker arm seat 5 and forms a rocker structure, the rear frame 2 pushes the shock absorber 4 to compress through the rocker arm seat 5 and the rocker arm 6, the shock absorber 4 compresses through back-and-forth swing, the swing angle of the rear frame 2 is further reduced, the jumping during shock absorption is reduced, and the comfort is better.
The technical principle of the present utility model is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the utility model and should not be taken in any way as limiting the scope of the utility model. Other embodiments of the utility model will occur to those skilled in the art from consideration of the specification and practice of the utility model without the need for inventive faculty, and are within the scope of the claims.
