Description
Technical Field
The utility model relates to a tricycle frame field, concretely relates to tricycle frame.
Background
The tricycle is a transportation tool formed by reforming a bicycle, and can carry people and goods. The tricycle is a combination of a rickshaw and a bicycle. The tricycle may be divided into a human tricycle, an electric tricycle, a child tricycle, a battery tricycle, etc. Generally, a tricycle frame is mounted on a tricycle.
However, the vertical pipe main beam on the existing tricycle frame mainly adopts a vertical bent pipe-shaped structure, the stress of the structure is unreasonable, the phenomenon of stress concentration is easy to occur on the tricycle frame body, so that the tricycle frame body is damaged due to stress deformation, the whole service life of the tricycle frame is reduced, and the front cross beam on the tricycle frame is a split welded structure, so that the welding deformation condition is easy to occur, and further the frame can not support the deviation prevention performance of the tricycle, so that a novel tricycle frame is urgently needed to solve the existing problems.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome the prior art not enough, a tricycle frame is provided at present, the problem that the main beam of the vertical pipe on the existing tricycle frame mainly adopts a vertical bent tubular structure is solved, the stress of the structure is unreasonable, the phenomenon of stress concentration is easy to occur on the frame main body, so that the frame main body is damaged due to stress deformation, the overall service life of the tricycle frame is shortened, a front cross beam on the tricycle frame is of a split welding structure, the welding deformation condition is easy to occur, and the frame cannot support the deviation preventing performance of the tricycle.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a tricycle frame, including frame main part, riser girder and front beam, frame main part one end is provided with the riser girder, the riser girder includes adapter sleeve and sets up connecting rod on the peripheral lateral wall of adapter sleeve, be provided with on the riser girder the front beam, on the front beam with the riser girder department of linking to each other is provided with mounting groove.
Through adopting above-mentioned technical scheme, through eight word structures riser girder and integral type structure the design of front beam not only makes the holistic atress structure of this frame more reasonable for the effort can the even effect be in the frame main part, it is concentrated to have reduced the atress, has improved the holistic life of this frame, has effectively reduced welding deformation moreover, plays the supporting role to the off tracking performance that prevents of vehicle, and the practicality is good.
Furthermore, the vertical pipe main beam is of a splayed structure and is welded with the frame main body.
Through adopting above-mentioned technical scheme, the riser girder atress of eight word structures is more reasonable, can effectively avoid the phenomenon is concentrated to the atress in the frame main part, avoids concentrating because of the atress and makes the frame main part warp the damage.
Furthermore, the connecting sleeve is welded with the connecting rod, and the connecting rod is of a hollow structure.
Through adopting above-mentioned technical scheme, through adapter sleeve can realize the convenient installation of riser girder.
Furthermore, the mounting groove is formed in the front cross beam, the front cross beam is of an integrated hollow structure, and the front cross beam is welded with the vertical pipe main beam and the frame main body.
By adopting the technical scheme, the front cross beam of the integrated structure can effectively avoid welding deformation.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
the utility model discloses a riser girder of eight characters structure and the design of the front beam of integral structure, not only make the stress structure of the whole frame more reasonable, make the acting force act on the frame main body evenly, reduce the stress concentration, improve the service life of the whole frame, but also effectively reduce the welding deformation, play a supporting role to the anti-deviation performance of the vehicle, the practicability is good.
