Description

Technical Field

[0001] This utility model relates to the field of electric two-wheeled vehicle technology, specifically to a load-bearing rear frame for electric two-wheeled vehicles. Background Technology

[0002] The rear frame of an electric vehicle is generally connected to the frame by welding. When carrying gas cylinders, the existing rear frame of an electric vehicle can only carry 1-2 cylinders at a time. Moreover, due to the shape of the gas cylinders, it is inconvenient to fix the gas cylinders to the rear frame. Packing the gas cylinders is also quite troublesome. When carrying two gas cylinders, the vehicle is bumpy and the gas cylinders will collide directly, which can easily lead to accidents. Therefore, we propose a new type of rear frame for electric vehicles. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a load-bearing rear frame for electric two-wheeled vehicles. By incorporating upper and lower supports and a load-bearing component, the ring handle of the gas cylinder can be easily hooked directly onto the load-bearing component, reducing the complexity and difficulty of packing and lowering transportation difficulty. At the same time, the upper and lower supports can also improve load-bearing strength and prevent damage to the rear frame. By incorporating a partition component, two gas cylinders on the same side can be separated to prevent direct collision between the gas cylinders, reducing the risk of accidents and improving safety.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A load-bearing rear frame for an electric two-wheeled vehicle is characterized in that it comprises: two symmetrically arranged upper and lower supports, a plurality of support members connected between the two supports, an edge extending inward along the bottom edge contour of the lower support, a pair of spaced mounting plates connected between the inner walls of the edge of the lower support, and at least one load-bearing component mounted on the top surface of the upper support.

[0008] Preferably, the bearing assembly includes a bearing member, which is mounted on the upper bracket along a direction parallel to the mounting plate. Two buffer members are respectively installed on the bottom of the bearing member, and each buffer member is installed on both sides of the top surface of the upper bracket. Both ends of the bearing member form a V-shaped structure.

[0009] Preferably, at least two of the carriers and a plurality of carrier components are arranged at intervals, and a partition component is installed on the upper support between adjacent carrier components.

[0010] Preferably, the partition assembly includes a base fixedly mounted on the upper bracket, with two vertical rods spaced apart on the top of the base, and a partition element rotatably mounted on each vertical rod.

[0011] Preferably, the contact surface between the separator and the gas cylinder is further provided with a buffer pad, and in the same partition assembly, a boss extends from the back of each separator.

[0012] Preferably, the buffer includes a support column mounted on the upper bracket, the support column extending through the bearing member, a spring sleeved on the support column, one end of the spring contacting the upper bracket, the other end of the spring contacting the bottom of the bearing member, and a nut installed at the end of the support column extending from the bearing member.

[0013] Preferably, each of the mounting plates has two oblong holes spaced apart.

[0014] Preferably, reinforcing struts are also installed between the inner walls of the lower support.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] See attached document Figure 1-3 A load-bearing rear frame for an electric two-wheeled vehicle includes two symmetrically arranged upper supports 1 and lower supports 2. Several support members 3 are connected between the two supports. The lower supports 2 have a square frame structure and extend inward along the bottom edge of the lower supports 2 to form an edge. It can be understood that since the upper supports 1 and lower supports 2 are symmetrically arranged, from the positional relationship, the edge of the upper supports 1 is located at the top.

[0032] In some embodiments, the support member 3 is an angle steel, and there are four angle steels, which are respectively set at the four corners of the bracket, connecting the two brackets and improving the overall support strength of the frame.

[0033] A pair of spaced mounting plates 6 are connected between the inner walls of the lower bracket 2 and each mounting plate 6 has two spaced waist-shaped holes. The mounting plate 6 fits into the rear seat of the electric two-wheeled vehicle. The waist-shaped holes are designed to allow bolts to be inserted into the holes and threadedly connected and fixed to the mounting holes (pre-drilled) of the rear seat.

[0034] A reinforcing rod 7 is also installed between the inner walls of the lower bracket 2. In some embodiments, the reinforcing rod 7 is installed in a direction parallel to or perpendicular to the mounting plate 6. In other embodiments, a portion of the reinforcing rods 7 is installed in a direction parallel to the mounting plate 6, while the remaining portion is installed in a direction perpendicular to the mounting plate 6.

[0035] It can be understood that the installation position of the reinforcing rod 7 does not interfere with the normal disassembly of the mounting plate 6 (specifically referring to the operation of bolting the mounting plate 6).

[0036] At least one bearing component 4 is installed on the top surface of the upper support 1. The bearing component 4 includes a bearing member 41. The bearing member 41 is installed on the upper support 1 along a direction parallel to the mounting plate 6. Two buffer members 42 are installed on the bottom of the bearing member 41. Each buffer member 42 is installed on both sides of the top surface of the upper support 1. Both ends of the bearing member 41 form a V-shaped structure, which makes it convenient for the top ring handle of the gas cylinder to be hung on the bearing member 41.

[0037] In some embodiments, when there are two or more carriers 41, several carrier components 4 are spaced apart, and a partition component 5 is installed on the upper support 1 between adjacent carrier components 4. The partition component 5 includes a base 51 fixedly installed on the upper support 1, and two vertical rods 52 are spaced apart on the top of the base 51. A separator 53 is rotatably mounted on each vertical rod 52 to separate adjacent gas cylinders on the same side, so as to avoid direct impact between adjacent gas cylinders during transportation. In some embodiments, a buffer pad is also attached to the contact surface between the separator 53 and the gas cylinder to further buffer the impact force of the gas cylinder. In other embodiments, in the same partition component 5, a boss is formed on the back side of each separator 53 to prevent the gap between two separators 53 from being too small, which would cause the lower half of adjacent gas cylinders to collide.

[0038] In some embodiments, the buffer 42 includes a support column mounted on the upper bracket 1, the support column extending through the carrier 41, a spring sleeved on the support column, one end of the spring contacting the upper bracket 1, the other end of the spring contacting the bottom of the carrier 41, and a nut installed at the end of the support column extending out of the carrier 41 to facilitate the fixing and limiting of the support column, the carrier 41 and the spring.
