[0001] The present application relates to the technical field of electric off-road vehicles, and in particular to a battery box structure and an electric off-road vehicle. Background Art

[0002] With the continuous development of electric vehicle technology and the growing awareness of environmental protection, electric off-road vehicles (EVs) have become increasingly popular among consumers in recent years as a low-carbon, environmentally friendly means of transportation. With their unique off-road performance and low noise pollution, EVs have shown broad application prospects in outdoor adventures, leisure and entertainment, and other fields.

[0003] In the overall structure of an electric off-road vehicle, the battery box is an important component that stores electrical energy and provides power to the motor. Some electric off-road vehicles place it externally to achieve good heat dissipation and make it easier to disassemble and maintain. However, the problem is that when the electric off-road vehicle is driving, the external battery box is prone to splashing water or mud on the road into the battery box through the vents on the battery box, which can easily affect the battery performance. Furthermore, the existing electric off-road vehicle battery compartment lacks the integrated function of directly observing the battery power and controlling the battery.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a battery box structure and an electric off-road vehicle to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve its technical problems is: first, a battery box structure, including: an upper cover, which is a box body with an opening downward, and a power switch mounting position, a shift switch mounting position, an instrument mounting slot and a charging hole are provided on the top of the upper cover, and a controller mounting point is provided inside the upper cover; a lower cover, which is a box body with an opening upward, and a battery compartment is formed, and the battery compartment is used to place batteries, and corresponding mounting holes are formed on the upper cover and the lower cover respectively, and the two are connected and fixed by fasteners provided in the mounting holes, and a plurality of ventilation slots are provided in an array on the corresponding two sides of the lower cover.

[0007] In some embodiments, a partition is formed inside the upper cover, and the partition divides the upper cover into two parts.

[0008] In some embodiments, power cord inlets are provided on corresponding sides of the upper cover.

[0009] In some embodiments, isolation ribs are formed on both sides of the battery compartment, and the isolation ribs extend vertically upward from the bottom of the battery compartment.

[0010] In some embodiments, it is characterized in that a plurality of drainage holes are opened on both sides of the bottom of the battery compartment, and the drainage holes are arranged between the ventilation slot and the isolation rib.

[0011] In some embodiments, the battery box is adapted for 24V or 36V batteries.

[0012] In some embodiments, fixing bracket mounting grooves are formed on the upper cover and the lower cover.

[0013] In a second aspect, the present application proposes an electric off-road vehicle, comprising a frame, a platform formed on the frame, and a motor and a battery box structure as described in any one of the first aspects mounted on the platform.

[0014] The beneficial effects of this application are:

[0015] 1) Several ventilation slots are opened on both sides of the battery box to achieve ventilation and heat dissipation effects. Isolation ribs are set in the battery compartment close to the ventilation slots to effectively block rainwater and mud from splashing into the battery compartment through the ventilation slots. Furthermore, several drainage holes are opened between the isolation ribs and the ventilation slots to discharge rainwater and other impurities out of the battery compartment to prevent them from affecting the normal use of the battery.

[0016] 2) By integrating the shift switch, power switch, instrument, charging port and other control and display components on the battery box, users can directly complete operations such as turning the machine on and off, adjusting the gear, checking the instrument readings and charging on the battery box without having to find and connect multiple independent components. This makes operation more convenient, reduces connection lines, reduces costs and makes maintenance easier. BRIEF DESCRIPTION OF THE DRAWINGS
