[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a battery box structure for electric bicycles. The design of the entire battery box structure makes installation and removal of the battery box simple and quick, while ensuring the stability and safety of the battery box on the electric bicycle. Users can easily remove the battery box for charging or replacement as needed, without complicated operations or tools.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An electric bicycle battery box structure includes a frame tube, on which two fixing sleeves are fitted, and fixing bolts are threaded to the side walls of the fixing sleeves. Two fixing holes that are adapted to the fixing bolts are provided on the side walls of the frame tube.
[0008] A vertical plate is fixedly installed between the two fixed brackets, and a support plate is fixedly installed on the outside of the vertical plate. A battery box is detachably connected to the upper end of the support plate, and two mounting components for mounting the battery box are symmetrically arranged on the vertical plate.
[0009] Preferably, the front end of the fixing bolt is unthreaded and located inside the fixing hole.
[0010] Preferably, the tray is a right-angled U-shaped plate, and a reinforcing frame is fixedly installed at the upper end. The reinforcing frame consists of two cooperating inclined plates.
[0011] Preferably, the mounting assembly includes a slide groove fixedly mounted on the side wall of the vertical plate, an insert plate slidably connected inside the slide groove, and the insert plate and the slide groove are elastically connected by two tension springs;
[0012] The side wall of the vertical plate has an opening that communicates with the sliding groove, and a pull plate is slidably connected inside the opening. The pull plate is fixedly connected to the insert plate.

[0025] Reference Figures 1-3 An electric bicycle battery box structure includes a frame center tube 1. Two fixing sleeves 2 are fitted onto the frame center tube 1. Fixing bolts 10 are threadedly connected to the side walls of the fixing sleeves 2. The front ends of the fixing bolts 10 are unthreaded and located inside fixing holes 3. Two fixing holes 3 are formed on the side walls of the frame center tube 1, which are adapted to the fixing bolts 10. The two fixing sleeves 2 are initially fixed by the fixing bolts 10 on the side walls engaging with the fixing holes 3 on the frame center tube 1. The unthreaded front ends of the fixing bolts 10 can be smoothly inserted into the fixing holes 3 and are threaded onto the side walls of the fixing sleeves 2, thereby ensuring that the fixing sleeves 2 are securely installed on the frame center tube 1.
[0026] A vertical plate 4 is fixedly installed between the two fixed brackets 2. A support plate 9 is fixedly installed on the outside of the vertical plate 4. The support plate 9 is a right-angled U-shaped plate, and a reinforcing frame is fixedly installed at the top. The reinforcing frame consists of two cooperating inclined plates. The design of the support plate 9 not only provides a stable support surface for the battery box 6, but also further enhances the stability of the structure through the reinforcing frame at its top, preventing the battery box 6 from shaking or shifting during installation or driving.
[0027] The upper end of the tray 9 is detachably connected to the battery box 6. Two mounting components for mounting the battery box 6 are symmetrically arranged on the vertical plate 4. The mounting components include a slide groove 13 fixedly mounted on the side wall of the vertical plate 4. An insert plate 8 is slidably connected inside the slide groove 13. The insert plate 8 is a U-shaped plate, and the side wall of the extended end is provided with a slope. The insert plate 8 and the slide groove 13 are elastically connected by two tension springs 14. When the insert plate 8 is not subjected to external force, the tension springs 14 will keep the insert plate 8 in a retracted state, that is, the U-shaped part of the insert plate 8 will be inserted into the slot 7 of the battery box 6, thereby locking the battery box 6.
[0028] The side wall of the vertical plate 4 has an opening 12 that communicates with the slide groove 13. A pull plate 11 is slidably connected inside the opening 12. The pull plate 11 is fixedly connected to the insert plate 8. The side wall of the battery box 6 has two slots 7 that are compatible with the insert plate 8. A pull rod 5 for lifting the battery box 6 is fixedly installed at the upper end of the battery box 6.
[0029] Working principle:
[0030] During installation, the battery box 6 is placed on the upper end of the tray 9. Meanwhile, since the insert plate 8 is a U-shaped plate design with one end extending outward and having a bevel, the insert plate 8 can be squeezed outward. When the insert plate 8 is aligned with the slot 7, under the action of the tension spring 14, the insert plate 8 is inserted into the slot 7 on the side wall of the battery box 6.
[0031] When the insert plate 8 is not subjected to external force, due to the elastic force of the tension spring 14, the insert plate 8 will remain in a retracted state, that is, the U-shaped part of the insert plate 8 will be inserted into the slot 7 of the battery box 6. In this way, the battery box 6 is locked on the tray 9 and cannot be easily moved or detached;
[0032] When it is necessary to release the battery box 6, the user can slide the pull plate 11, which is fixedly connected to the insert plate 8. The pull plate 11 is slidably connected to the side wall of the vertical plate 4 through the opening 12. The user only needs to pull the pull plate 11 outward to drive the insert plate 8 to slide in the slide groove 13, thereby overcoming the elastic force of the tension spring 14 and causing the insert plate 8 to disengage from the slot 7 of the battery box 6.
[0033] Once the insert 8 is completely dislodged from the slot 7, the battery box 6 is no longer locked, and the user can easily lift the battery box 6 using the lever 5 at its top to perform operations such as replacement or charging.
[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
