The existing support frame for supporting the front wheel of the two-wheeled electric vehicle is usually made of one material, such as all aluminum or all iron, and the production efficiency, the production cost and the processing precision are difficult to be considered simultaneously. In order to solve the technical problem, the application provides a supporting structure, the supporting structure is made of at least two materials, and the purposes of improving the production efficiency, reducing the production cost and improving the processing precision are achieved by utilizing the process performance and the service performance of different materials.
Referring to fig. 1 and 2, the present embodiment provides a supporting structure 100, which includes a damper cylinder 110 and a bracket 120 disposed on an outer wall of the damper cylinder 110, where the bracket 120 includes a first bracket 121 and a second bracket 122 wrapped on an outer wall of the first bracket 121, the second bracket 122 partially exposes the first bracket 121, the exposed first bracket 121 is fixedly connected to the outer wall of the damper cylinder 110, a material of the first bracket 121 is the same as a material of the damper cylinder 110, and a material of the first bracket 121 is different from a material of the second bracket 122.
As shown in fig. 1, the supporting structure 100 includes a damper cylinder 110 and a bracket 120, the damper cylinder 110 is hollow inside and is used for accommodating structures such as dampers, the bracket 120 is fixedly connected to an outer wall of the damper cylinder 110 and includes a first bracket 121 and a second bracket 122, the second bracket 122 wraps the first bracket 121 and is fixedly connected to the first bracket 121 to form a structure that an outer layer wraps an inner layer, the first bracket 121 is used for fixedly connecting to the damper cylinder 110, and the second bracket 122 is used for fixing a front wheel axle and a front disc brake. The second bracket 122 is provided with a notch to partially expose the first bracket 121, and the first bracket 121 and the damper cylinder 110 are made of the same material to facilitate connection therebetween. Because the first support 121 and the damper cylinder 110 do not involve the problems of matching and the like, and the requirement on the machining precision is not high, the first support and the damper cylinder can be made of materials which are low in cost and convenient to machine, so that the production cost is reduced, and the production efficiency is improved. The second bracket 122 is made of a material capable of being processed with high precision due to the problem of matching with the front wheel axle and the front disc brake, so that the surface of the obtained second bracket 122 has high precision. The material for preparing the second bracket 122 may have the problems of low production efficiency and high processing cost, but because it is only applied to the local processing of the supporting structure 100, compared with the supporting structure 100 prepared from a single material, the requirements of production cost, production efficiency and processing precision can be considered at the same time. As for the specific materials for preparing the damper cylinder 110, the first bracket 121 and the second bracket 122, those skilled in the art should be able to make reasonable selections according to actual needs, and are not limited to the specific materials.
In this embodiment, the first bracket 121 may be formed by stamping or laser cutting, the second bracket 122 may be wrapped outside the first bracket 121 by using a casting or die-casting process, and after forming a structure in which an outer layer wraps an inner layer, the first bracket 121 may be welded to an outer wall of the damper cylinder 110, so as to fixedly connect the bracket 120 and the damper cylinder 110. For the convenience of welding, referring to fig. 2 in combination, the second bracket 122 may expose a bottom edge of the first bracket 121, and at the same time, the bottom edge of the second bracket 122 may be designed in an arc shape having the same radius as the outer wall of the damper cylinder 110 to wrap the surface of the damper cylinder 110.
As described above, the support structure 100 includes the damper cylinder 110 and the bracket 120 disposed on the outer wall of the damper cylinder 110, the bracket 120 includes the first bracket 121 and the second bracket 122 wrapped on the outer wall of the first bracket 121, the second bracket 122 partially exposes the first bracket 121, the exposed first bracket 121 is fixedly connected to the outer wall of the damper cylinder 110, the material of the first bracket 121 is the same as that of the damper cylinder 110, and the material of the first bracket 121 is different from that of the second bracket 122. The supporting structure 100 is prepared from different materials according to different functions of the shock absorber cylinder 110, the first support 121 and the second support 122, so that the production cost is reduced, the processing efficiency is improved, the processing precision is also ensured, and the supporting structure 100 can be installed in a matching manner with a front wheel shaft and a front disc brake.
Alternatively, in an implementation of the embodiment of the present invention, the material of the damper cylinder 110 and the first bracket 121 is iron, and the material of the second bracket 122 is aluminum.
The cost of iron is low, the process for preparing the shock absorber cylinder 110 and the first support 121 by using iron is simple, machining is not involved, so that the machining efficiency is high, and although the precision of the obtained product is low, the shock absorber cylinder 110 and the first support 121 do not involve the problem of matching, so that the function of the supporting structure 100 is not affected. Although the cost of aluminum is high, machining can be adopted, and the second bracket 122 prepared through multiple processes has high surface precision and can be used for being matched with a front wheel shaft and a front disc brake to be installed.

The first through hole 1211 is used to position the first support 121 when the second support 122 is formed outside the first support 121, so that the first support 121 does not move to affect the processing of the second support 122. For example, as shown in fig. 2, when the second bracket 122 is formed by casting or die-casting, the first bracket 121 is fixed to the casting mold by the first through hole 1211 engaged with the boss of the casting mold. When the second bracket 122 is finished, the first bracket 121 and the second bracket 122 are fixed to the positioning mold by the engagement of the first through hole 1211 with the boss of the positioning mold.

When the first through-hole 1211 includes two or more, the sectional shape of the first through-hole 1211 is not limited and may be circular, rectangular, etc. The second through hole 1212 includes at least one, and the cross-sectional shape is not limited, and those skilled in the art should be able to make a reasonable choice and design according to actual needs.
