Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a fully enclosed electric vehicle frame that facilitates power supply replacement. Background Technology

[0002] Electric bicycles are an important part of modern transportation, suitable for short-distance travel in various environments such as cities and rural areas, and are characterized by zero emissions, low noise, and high energy efficiency. However, due to current technological limitations, electric bicycle batteries will suffer irreversible damage after a certain period of use and need to be replaced. In existing designs, the battery is mostly located at the foot pedal position, requiring the operator to insert the battery pack from above into the battery compartment and then use bolts, straps, and other methods to position and install it, which is a cumbersome operation. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed fully enclosed electric vehicle frame that facilitates power supply replacement, thereby solving the aforementioned deficiencies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a frame body, with side panels installed on the front and rear sides of the foot pedal area on the frame body, a rear panel connected to the rear end of the side panels, and several guide rails parallel to the two side panels. An explosion-proof battery box for placing batteries is slidably installed on the guide rails, and a limiting structure is provided at the front end of the guide rails.

[0005] Preferably, the guide rail has an inverted "T"-shaped guide limiting groove, and the bottom of the explosion-proof battery box is connected to a guide slider that matches the shape of the guide limiting groove. The guide slider is inserted into the guide limiting groove, and several rollers are installed on both sides of the guide limiting groove above the guide rail.

[0006] Preferably, the front side of the guide slider is aligned with the front side of the explosion-proof battery box, and the length of the guide slider is less than the length of the explosion-proof battery box.

[0007] Preferably, the limiting structure includes two compression grooves respectively opened on both sides of the front end of the guide limiting groove, and a "V"-shaped spring sheet is provided in the compression groove, with one end of the spring sheet abutting against the front end of the guide slider.

[0008] Preferably, the explosion-proof battery box is provided with a power output port.

[0009] The beneficial effects of this utility model after adopting the above structure are:

[0010] This utility model adopts a side-mounted method for installing the explosion-proof battery box, which can reduce the manpower required and make the installation easier compared to the top-mounted method.

[0011] This utility model adopts a sliding rail installation method. During installation, the explosion-proof battery box is lifted, aligned, and then pushed in to complete the installation. The installation is convenient and quick, without the need for manual re-positioning. In addition, the explosion-proof battery box is automatically locked by spring plates, eliminating the need for bolt installation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figures 1-2 As shown, it includes a frame body 1. Side panels 2 are installed on the front and rear sides of the foot pedal area on the frame body 1. The rear end of the side panels 2 is connected to a rear panel 3. Several guide rails 4 are provided between the two side panels 2 and parallel to them. An explosion-proof battery box 5 for placing batteries is slidably installed on the guide rails 4. A limiting structure is provided at the front end of the guide rails 4.

[0021] The guide slide rail 4 has an inverted "T" shaped guide limiting groove 6. The bottom of the explosion-proof battery box 5 is connected to a guide slider 10 that matches the shape of the guide limiting groove 6. The guide slider 10 is inserted into the guide limiting groove 6. Several rollers 7 are installed on both sides of the guide limiting groove 6 above the guide slide rail 4.

[0022] The front side of the guide slider 10 is aligned with the front side of the explosion-proof battery box 5, and the length of the guide slider 10 is less than the length of the explosion-proof battery box 5.

[0023] The limiting structure includes two compression grooves 8 respectively opened on both sides of the front end of the guide limiting groove 6. The compression grooves 8 are provided with "V" shaped spring plates 9. One end of the spring plate 9 is ejected and abuts against the front end of the guide slider 10. The explosion-proof battery box 5 is provided with a power output port.

[0024] The principle and usage process of this utility model:

[0025] During installation, first insert the battery into the explosion-proof battery box 5 and connect the wires. Then, lift the explosion-proof battery box 5 and place it between the side baffles 2. The bottom rear end of the explosion-proof battery box 5 will first contact the roller 7. The side baffles 2 on both sides limit the left and right movement of the explosion-proof battery box 5. At this time, the explosion-proof battery box 5 can be pushed inward and the spring plates 9 will be pushed open to both sides. The spring plates 9 will be compressed into the compression groove 8. Since the length of the guide slider 10 is less than that of the explosion-proof battery box 5 and the guide limiting groove 6, the guide slider 10 has not yet entered the guide limiting groove 6. As the explosion-proof battery box 5 is pushed forward, the guide slider 10 gradually enters the guide limiting groove 6. Continue to push the explosion-proof battery box 5. When the explosion-proof battery box 5 contacts the rear baffle 3, the spring plates 9 lose pressure and automatically pop out, limiting the explosion-proof battery box 5 and preventing it from sliding outward. The installation is complete.

[0026] When the battery needs to be replaced, use a tool to press the spring plate 9 inward so that it retracts into the compression groove 8, and then pull out the explosion-proof battery box 5 for maintenance. Then, reinstall it in the same way as described above.

[0027] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
