[0035] Example

[0036] like Figure 1As shown, the load-bearing structure proposed in the embodiment of the present invention includes:

[0037] The bearing portion is used to connect with the vehicle frame body;

[0038] The bearing portion includes:

[0039] A first shell 1 and a second shell 2 are spliced ​​together to form a storage space 3. The storage space 3 is used to place the spliced ​​first shell 1 and second shell 2 on the vehicle frame body, and the side of the spliced ​​first shell 1 and second shell 2 facing away from the storage space 3 is used for the rider to step on.

[0040] Specifically, an electric vehicle is also called an electric vehicle, or a two-wheeled vehicle. It is a pure electric vehicle that is powered by a battery (battery) and driven by an electric motor (DC, AC, series-excited, or externally-excited). The electric vehicle includes a vehicle frame body and two wheel bodies. The vehicle frame body includes a vertical axis for installing a handlebar body and one wheel body, a cross frame for installing another wheel body, and a vertical frame installed on the cross frame. The vertical frame is used to install a seat body. The vehicle frame body, two wheel bodies, seat body, handlebar body and other components are all existing technologies and can be obtained through procurement.

[0041] It should be noted that the existing footrest is made up of three boards, which include a horizontal board and two vertical boards. The horizontal board is located between the two vertical boards and is respectively connected to the two vertical boards. When the staff is splicing, two people are needed, and each person holds a vertical board at the same time. The two people are located on both sides of the partial horizontal frame on the vehicle frame body. After adjusting to the appropriate position, one of the two people needs to hold the horizontal board, and the other person cooperates with the person holding the horizontal board to firmly fix the horizontal board between the two vertical boards, and make the horizontal board respectively resist the two vertical boards. After the third person fixes the horizontal board to the two vertical boards, the spliced ​​footrest is fixed to the partial horizontal frame on the vehicle frame body. This process is time-consuming and labor-intensive. For this reason, the present application provides a load-bearing structure to solve the technical problems existing in the prior art.

[0042] Specifically, the support structure includes a support portion, which can be a separate plate-shaped structure. Only one person is required to secure the support portion to a portion of the cross frame on the vehicle frame body, saving both manpower and the time required to install the pedals. The plate-shaped support portion can be of regular or irregular shape, and this application does not limit this.

[0043] The present application provides another embodiment of the load-bearing part, that is, the load-bearing part can also be a load-bearing part spliced ​​together by multiple components, and the load-bearing part includes a first shell 1 and a second shell 2, and the first shell 1 and the second shell 2 are spliced ​​together to form a accommodating space 3, so that the load-bearing part can cross the partial cross frame on the vehicle frame body through the accommodating space 3 and be connected to the partial cross frame on the vehicle frame body. The side of the load-bearing part away from the accommodating space 3 can be convenient for the rider to step on. With this structural design, only two staff members are needed to complete the assembly of the load-bearing part, that is, one person holds the first shell 1 and the other person holds the second shell 2, and they are respectively located on both sides of the partial cross frame on the vehicle frame body. After adjusting to the appropriate position, the first shell 1 and the second shell 2 are spliced. After splicing, each staff member can use his free hand to fix the structure on the corresponding side, effectively solving the technical problems existing in the prior art.

[0044] The first shell 1 and the portion of the cross frame on the vehicle frame body, as well as the second shell 2 and the portion of the cross frame on the vehicle frame body, can be connected in a detachable manner or in a fixed manner, such as bolt connection, snap connection, plug connection, bonding, and welding. The first shell 1 and the second shell 2 can be directly connected or not connected, for example, the contact surfaces between the first shell 1 and the second shell 2 can abut against each other, or the contact surfaces between the first shell 1 and the second shell 2 can be plugged in through a limiting structure. The staff can choose according to actual needs, and this application does not limit it.

[0045] The load-bearing structure provided by the embodiment of the present invention only requires two workers to complete the assembly of the load-bearing part during assembly, that is, one person holds the first shell 1 and the other person holds the second shell 2, and they are respectively located on both sides of the partial cross frame on the vehicle frame body. After adjusting to the appropriate position, the first shell 1 and the second shell 2 are spliced ​​together. After splicing, each worker can use his or her free hand to fix the structure on the corresponding side, effectively solving the technical problems existing in the prior art.

[0046] In a specific implementation, the bearing part is made of magnesium alloy material.

[0047] Specifically, the bearing part is made of magnesium alloy material, which has the characteristics of light weight and high strength (magnesium alloy is the lightest metal structural material in engineering applications, with low density and high specific strength. Its density is about 2 / 3 of aluminum and 1 / 4 of iron, but without reducing the strength of the parts, it can reduce the weight of aluminum or iron parts). It also has good mechanical properties (the specific stiffness of magnesium alloy is close to that of aluminum alloy and steel, much higher than engineering plastics, and has good seismic and noise reduction properties. The tensile strength of its castings is comparable to that of aluminum alloy castings, generally up to 250MPa, and up to more than 600MPa, with yield strength and ductility The elongation is not much different from that of aluminum alloy); it also has excellent corrosion resistance (magnesium alloy has good corrosion resistance, electromagnetic shielding and radiation protection properties, and can be 100% recycled and reused), excellent impact resistance (when subjected to impact load, the energy absorbed by magnesium alloy is half that of aluminum alloy, it has good elongation and can absorb impact energy without breaking) and excellent processing performance (magnesium alloy has good die-casting forming performance, and the minimum wall thickness of die-casting parts can reach 0.5mm, which is suitable for manufacturing various die-casting parts for automobiles. At the same time, magnesium alloy has good machinability, less cutting resistance than other metals, and faster processing speed).

[0048] In the past, electric vehicle pedals were mostly made of aluminum alloy, steel or plastic. Although pedals made of plastic and aluminum alloy are relatively light, their strength and wear resistance are sometimes difficult to meet the requirements of high-intensity use. Although steel pedals are strong, they are heavy, which increases the unsprung mass of the vehicle and also has a certain impact on the driving stability and controllability. For this reason, the load-bearing part of the present application is made of magnesium alloy material, which not only meets the use requirements of strength and wear resistance, but also reduces the weight of the load-bearing part, will not affect the driving stability and controllability, and effectively solves the technical problems existing in the prior art.
