Embodiment Construction
[0033] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] In order to achieve the purpose of the present invention, as figure 1 As shown, in one of the embodiments of the present invention, a composite frame structure is provided for a tricycle or a four-wheel vehicle, including:
[0035] The main beam comprises two foundation main beams 10 and two upper support beams 40, the two foundation main beams 10 are horizontally arranged in parallel, the heads of the two upper support beams 40 are respectively fixed on the front ends of the two foundation main beams 10, and the two upper support beams 40 are The tail parts are connected to each other, the two upper support beams 40 are inclined from low to high from the head to the tail, and the second foundation main beam 10 and the second upper support beam 40 are prisms with a set length. The prisms are not limited to solid or hollow structures. ...

The invention discloses a compound type frame structure for tricycles or quadricycles. The compound type frame structure comprises a main beam and at least two cross beams. The main beam comprises two basic main beams and two upper supporting beams, the heads of the two upper supporting beams are fixed at the front ends of the two basic main beams respectively, the tails of the two upper supporting beams are connected with each other, and clamping grooves for mounting a shell are formed in the opposite side faces of the two basic main beams, the opposite side faces of the upper supporting beams as well as the opposite side faces of the basic main beams and the corresponding upper supporting beams. Two ends of the cross beams are connected onto the two basic main beams. Compared with the prior art, the compound type frame structure has the advantages that the upper supporting beams are arranged at the front ends of the basic main beams, the clamping grooves for mounting the shell are formed in the opposite side faces of the two basic main beams, the opposite side faces of the upper supporting beams as well as the opposite side faces of the basic main beams and the corresponding upper supporting beams, clamping groove structures are used for the basic main beams and the upper supporting beams to mount the shell, extra connecting pieces are avoided, and accordingly more rapidity and convenience in mounting and demounting and low cost are achieved.
Description
technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a composite vehicle frame structure. Background technique [0002] As a fast and convenient means of transportation, vehicles are widely used in people's lives. In the prior art, most bicycles do not use shells, which cannot provide sunshade, windshield, and rain protection functions for riding in summer, winter or rainy days, which is very inconvenient. Moreover, the frame and body of the vehicle are mainly welded structures, which are complicated to process and costly. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a composite vehicle frame structure. [0004] In order to achieve the above object, technical scheme of the present invention is as follows: [0005] The invention provides a composite frame structure for a tricycle or a four-wheel vehicle, comprising: [0006] The main...
