Description

Technical Field

[0001] This utility model relates to the field of pedal-related technology, and more specifically, to an electric vehicle frame made entirely of sheet metal. Background Technology

[0002] The frame of an electric vehicle is an important component. Currently, to ensure the overall structural strength of the frame, electric vehicle frames are manufactured using a method of bending steel pipes and then welding them in stages. Electric vehicles on the market that use this old method to produce frames are relatively heavy, which is not lightweight enough, resulting in higher energy consumption and less smooth handling.

[0003] Existing electric vehicle frames mainly adopt a frame structure with no protective plates around them, which can easily lead to low frame strength. At the same time, the frame is easily damaged by flying stones during electric vehicle operation, which can damage the internal wiring and mechanical components. In addition, after the battery is installed, the electric vehicle frame is mainly protected by a plastic shell, which is not very effective and is easily damaged by impact, affecting the overall service life.

[0004] Therefore, a fully sheet metal electric vehicle frame is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric vehicle frame made entirely of sheet metal to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle frame made entirely of sheet metal, comprising a frame body and a front mounting component. The frame body further comprises a first frame, a second frame, and four uprights. The four uprights are fixedly connected between the first frame and the second frame. The front mounting component is fixedly installed inside the first frame and the second frame. The top of the first frame is provided with two slots, and a rotating rod is rotatably connected inside each of the two slots. A protective frame is fixedly connected to the outside of each of the two rotating rods. Two connecting components are provided between the two protective frames. A mounting groove is provided between the first frame, the second frame, and the uprights. A first sheet metal plate and a second sheet metal plate are installed inside the multiple mounting grooves.

[0007] Preferably, the first frame, the second frame, and the column are fixedly connected by welding.

[0008] Preferably, both of the connecting components include a mounting hole, a threaded groove, a stud, and a drive disk. The mounting hole is located inside one of the protective frames and extends to both sides. The threaded groove is located on one side of the protective frame corresponding to the mounting hole. The stud is installed inside the mounting hole. The drive disk is fixedly connected to one end of the stud. One end of the stud matches the threaded groove, and the stud and the threaded groove are threaded together.

[0009] Preferably, a limiting disc is fixedly connected to the outside of the stud.

[0010] Preferably, both the first sheet metal plate and the second sheet metal plate are equipped with a plurality of locking bolts that extend to one side. One end of each locking bolt is threaded into the mounting groove. Each locking bolt has a drive groove on one side, and the drive groove is a regular hexagon.

[0011] Preferably, the two protective frames are fixedly installed inside the threaded groove by studs.

[0012] Preferably, the protective frame can rotate 180 degrees via a rotating rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the prior art, the electric vehicle frame with all sheet metal parts, through the setting of locking bolts, first sheet metal plate and second plate, after the first sheet metal plate and second plate are fixed and installed by locking bolts, can work with the first frame and second frame to increase its own strength, making the electric vehicle more stable when riding. At the same time, the first sheet metal plate and second plate can play a protective role, avoiding damage to the internal wiring and mechanical parts of the frame caused by flying stones, thus playing a protective function.

[0015] 2. Compared with the existing technology, this all-sheet metal electric vehicle frame, by setting a rotating rod, a protective frame and a connecting component, can connect two protective frames by installing them into the threaded groove with studs, which facilitates the protection of the plastic shell above the battery, improves the protection performance, avoids damage during impact, and increases the overall service life. At the same time, the protective frame increases the unfolding space when it opens to both sides, making it convenient for the legs to be placed when the electric vehicle is carrying goods, thus improving the comfort of use.

The frame body also includes a first frame 3, a second frame 5, and four uprights 7. The four uprights 7 are fixedly connected between the first frame 3 and the second frame 5. The front mounting component 4 is fixedly installed inside the first frame 3 and the second frame 5. The top of the first frame 3 has two slots 2, and a rotating rod 1 is rotatably connected inside each slot 2. A protective frame 9 is fixedly connected to the outside of each rotating rod 1. The rotation of the rotating rod 1 facilitates the rotation of the protective frame 9. Two connecting components are provided between the two protective frames 9. A mounting groove 8 is provided between the first frame 3, the second frame 5, and the uprights 7. Multiple mounting slots 8 house a first sheet metal plate 10 and a second sheet metal plate 6, facilitating the installation of the first sheet metal plate 10 and the second sheet metal plate 6 into the mounting slots 8. Both connecting components include mounting holes 15, threaded grooves 12, studs 14, and drive discs 11. The mounting holes 15 are located inside one of the protective frames 9 and extend to both sides. The threaded grooves 12 are located on one side of the protective frame 9 corresponding to the mounting holes 15. The studs 14 are installed inside the mounting holes 15. The drive discs 11 are fixedly connected to one end of the studs 14. One end of the studs 14 matches the threaded grooves 12, and the studs 14 and the threaded grooves 12 are threaded together. By installing the studs 14 into the threaded grooves 12, the protective frames 9 can be connected.

[0024] In use, the protective frame 9 can be rotated to be above the first frame 3 by rotating the rotating rod 1. After that, the drive disk 11 is rotated. After the drive disk 11 rotates, it can drive the stud 14 to rotate. After the stud 14 rotates, it is driven to be installed inside the threaded groove 12, so that the two protective frames 9 are connected. This can protect the plastic above the battery. At the same time, when the protective frame 9 is opened to both sides, it increases the unfolding space, making it convenient for the legs to be placed when the electric vehicle is carrying goods, thus improving the comfort of use.
