Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle battery box technology, and in particular relates to a combined battery box structure for electric vehicles. Background Technology

[0002] Driven by environmental protection demands and the transformation of the energy structure, electric vehicles have rapidly emerged in the transportation sector due to their outstanding advantages such as zero emissions, low noise, and low operating costs. Whether it is daily urban commuting, short-distance leisure travel, or logistics and delivery, electric vehicles are playing an increasingly important role, and their market share continues to rise.

[0003] As the core power source of electric vehicles, the specifications and capacity of batteries vary significantly depending on the vehicle model and usage requirements. Long-range electric vehicles often require large-capacity, tall batteries to meet long-distance driving needs; while short-distance commuter electric vehicles, in order to control costs and vehicle weight, mostly use small-capacity, short-sized batteries. This necessitates that the battery pack structure of electric vehicles must have good adaptability, capable of accommodating the installation of batteries of different heights.

[0004] However, the current mainstream electric vehicle battery box structure has many drawbacks. Most battery boxes adopt a fixed design, and the depth of the battery compartment is determined during production, making it impossible to adjust according to the actual height of the installed battery. This often leads to incompatibility between the battery and the battery compartment when replacing batteries of different heights. If the battery height exceeds the battery compartment depth, the battery cannot be installed at all; if the battery height is less than the battery compartment depth, the battery will move around freely inside the battery compartment, which will not only accelerate the wear and tear of internal battery components and shorten battery life, but may also cause serious safety hazards such as short circuits due to battery movement, threatening the normal use of the electric vehicle and the personal safety of the user.

[0005] Therefore, the inventors dedicated themselves to designing a battery box for electric vehicles to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a combined battery box structure for electric vehicles, which allows for adjustment of the depth of the battery compartment so that the depth of the battery compartment matches the height of the battery, thereby improving the adaptability of the battery box to batteries of different heights.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A combined battery box structure for an electric vehicle includes a side guard frame located at the footrest of the electric vehicle and a foot pedal covering the top of the side guard frame. The bottom of the side guard frame is open and covered with a bottom cover. The bottom cover, the side guard frame, and the foot pedal together form a battery compartment. The side guard frame is adjustablely connected to the bottom cover through multiple adjusting components to adjust the distance between the bottom cover and the side guard frame.

[0009] As an improvement to the combined battery box structure of the electric vehicle of this utility model, each of the adjusting components is provided with at least one set of fixing holes, and the side wall of the bottom cover is provided with multiple sets of adjusting holes at positions opposite to the individual adjusting components. On the same adjusting component, all the fixing holes are fixedly connected to a portion of the adjusting holes at corresponding positions on the bottom cover by adjusting screws.

[0010] As an improvement to the combined battery box structure of the electric vehicle of this utility model, the number of fixing holes on the same adjusting component is two sets, and the number of adjusting holes opposite to a single adjusting component is greater than or equal to three sets. Each set of fixing holes includes two fixing holes, and each set of adjusting holes includes two adjusting holes.

[0011] As an improvement to the combined battery box structure of the electric vehicle of this utility model, each of the fixing holes is circular, and each of the adjusting holes is waist-shaped and arranged laterally along the bottom cover.

[0012] As an improvement to the combined battery box structure of the electric vehicle of this utility model, the top of the bottom cover is open and the inner bottom wall is provided with multiple bottom holes.

[0013] As an improvement to the combined battery box structure of the electric vehicle of this utility model, the width of the bottom cover facing the front of the electric vehicle is greater than the width of the bottom cover facing the rear of the electric vehicle.

[0014] As an improvement to the combined battery box structure of the electric vehicle of this utility model, all the adjusting components are located between the bottom cover and the side frame.

[0015] As an improvement to the combined battery box structure of the electric vehicle of this utility model, the top of the adjusting member is bent to the side opposite to the battery compartment to form a bent part, and the bent part is attached to the step on the inner wall of the side guard frame.

[0016] As an improvement to the combined battery box structure of the electric vehicle of this utility model, the bent part is provided with a waist-shaped locking hole, and the locking hole is fixedly connected to the side guard frame by locking screws.

[0017] As an improvement to the combined battery box structure of the electric vehicle of this utility model, the adjusting member is elongated and its upper end width is smaller than its lower end width.

[0018] Compared with the prior art, the combined battery box structure of the electric vehicle of this utility model has an open bottom of the side guard frame located at the foot pedal of the electric vehicle and a bottom cover. The bottom cover, the side guard frame and the foot pedal together form the battery compartment. At the same time, the side guard frame is adjusted and connected to the bottom cover through multiple adjusting parts, so that the bottom cover can be raised and lowered according to the battery height, so that the depth of the battery compartment matches the height of the battery. This design not only improves the adaptability of the battery box to batteries of different heights, but also has the advantages of simple operation and stable structure. Attached image description:
