[0025] The present application will be further described in detail below in combination with the drawings and specific embodiments: Embodiment 1:

[0026] Referring to Figure 1-Figure 7 A sand vehicle battery heat dissipation installation box and a sand vehicle, the sand vehicle is configured with a battery heat dissipation installation box, a power battery is configured in the installation box, and a hub motor is configured on the rear wheel of the vehicle, the power battery is used to provide power support for the hub motor, wherein the hub motor is involved into the power system at the starting stage of the vehicle or when the vehicle accelerates to overtake, so as to assist the vehicle to start quickly or to overtake quickly.

[0027] The heat dissipation installation box comprises a base 1, a battery box 2 for placing a battery and a conversion device 3 for converting heat dissipation mode are configured on the base 1, heat dissipation grooves 21 for ventilation and heat dissipation are uniformly arranged on the peripheral wall of the battery box 2, so that the wind from outside blows into the battery box 2 to dissipate heat for the battery fixedly placed inside, a guide rod 211 is arranged on the heat dissipation groove 21, a heat dissipation block 22 is slidingly arranged on the guide rod 211 in a guided manner, a sliding groove 221 is arranged on the heat dissipation block 22, the heat dissipation block 22 is slidingly arranged on the guide rod 211 of the heat dissipation groove 21 in a guided manner through the sliding groove 221, the heat dissipation block 22 moves forward and backward to block or open the heat dissipation groove 21, a first elastic member is arranged between the guide rod 211 and the heat dissipation block 22, and the first elastic member is used to move the heat dissipation block 22 into the battery box 2 to make the heat dissipation groove 21 in an open state.

[0028] The upper and lower ends of the inner wall of the heat dissipation block 22 are provided with top contact blocks 222. The protruding top contact blocks 222 make the inner wall of the heat dissipation block 22 into a C shape. The battery body of the vehicle is fixedly installed in the battery box 2. There is a gap between the battery body and the surrounding walls of the battery box 2 to allow air circulation for heat dissipation. The heat dissipation block 22 slides into the battery box 2 under the action of the first elastic member, and the top contact blocks 222 thereon touch the end wall of the battery body, thereby preventing the middle area on the inner wall of the heat dissipation block 22 from contacting the battery body, so that air can flow through this gap. The heat dissipation block 22 is made of thermally conductive material, so the heat on the battery body is absorbed through the upper and lower top contact blocks 222. When the air flows into the heat dissipation groove 21, it passes through the heat dissipation block 22 and dissipates heat through the heat dissipation block 22. At the same time, the air flows through the gap between the heat dissipation block 22 and the battery body to dissipate heat to the battery body.

[0029] A contact plate 223 is provided in the middle position of the inner wall of the heat dissipation block 22, and one end of the annular folding cover is connected to the contact plate 223, and the other end of the annular folding cover is tightly fitted in the middle position of the inner wall of the heat dissipation block 22, so that the annular folding cover, the inner wall of the heat dissipation block 22 and the contact plate 223 form a sealed chamber, and the heat dissipation block 22 is connected to the liquid cooling device, and the upper and lower top contact blocks 222 are respectively provided with an injection port and an outflow port, and the two ports are connected with the sealed chamber, and the injection port and the outflow port are respectively connected with the circulation pipe of the liquid cooling device. After the liquid cooling device is started, the coolant can be injected into the sealed chamber from the injection port, and flow out from the outflow port and return to the liquid storage tank, thereby circulating heat.

[0030] The outlet is provided with a pressure valve. When the pressure at the outlet reaches a set value, the outlet opens, thereby allowing the coolant to circulate. The sealed chamber is initially in a deflated state. After the coolant is injected into the sealed chamber, the outlet does not open because the pressure in the sealed chamber does not reach the set value. At this time, the coolant remains in the sealed chamber, and the annular folding cover is an annular accordion cover, which allows the sealed chamber to expand, pushing the contact plate 223 forward to contact the side wall of the battery body. The contact plate 223 is made of heat-conducting metal. At this time, the coolant continues to be injected, causing the heat sink 22 to move outward from the battery box 2. Eventually, the inclined surface of the front end of the heat sink 22 contacts the heat sink 21, thereby blocking the heat sink 21. At this time, the heat sink 22 can no longer move, and the space inside the sealed chamber no longer expands. At this time, the injection port continues to inject coolant, thereby increasing the pressure in the sealed chamber. When the pressure reaches the set value, the outlet opens, allowing excess coolant to flow back into the liquid storage tank through the pipeline.

[0031] And the pressure in the sealed chamber is maintained at a set pressure, and the peripheral wall of the battery box 2 is provided with a heat dissipation groove 21, and the heat dissipation block 22 is arranged in each heat dissipation groove 21, and the battery body is in contact with the heat dissipation block on the four peripheral surfaces, and the heat dissipation block 22 on the four peripheral surfaces is pressed tightly on the side surface of the battery body, preventing the battery body from deforming due to excessive temperature, and the contact plate 223 is in contact with the battery body, and the cooling in the sealed chamber is realized by heat exchange through the contact plate 223, thereby cooling the battery body.

[0032] Wherein the liquid cooling device includes a liquid storage tank and a circulating pump, the circulating pump is powered by the battery body, the circulating pump can rotate forward or reverse, when the heat dissipation operation is performed, the circulating pump rotates forward, and the cooling liquid in the liquid storage tank is injected into the sealed chamber from the injection port, and the battery body is fixed and supported, and the battery body is cooled by liquid cooling, when the temperature of the battery body decreases to the set temperature and the humidity decreases to the set value, the air cooling can be started at this time, at this time the circulating pump is reversed, the pressure valve on the outlet is a one-way valve, therefore the circulating pump reverses to suck the cooling liquid in the sealed chamber back to the liquid storage tank, thereby the space of the sealed chamber is reduced and returns to the initial state, the heat dissipation block 22 is pressed on the battery body by the top contact block 222 under the action of the first elastic member, and the battery box 2 returns to the air cooling state.

[0033] The base 1 is also provided with a filter screen device 4 for filtering the air entering the battery box 2, the filter screen device 4 includes a filter screen 41 and a rotating roller 42, the rotating roller 42 is rotatably arranged on the base 1, the battery box 2 is a cuboid, and four rotating rollers 42 are respectively located outside the four right angles of the cross section of the battery box 2, the filter screen 41 is tightly sleeved on the four rotating rollers 42, so that the filter screen 41 surrounds the four peripheral surfaces of the battery box 2 upward, one of the rotating rollers 42 is a power roller or a rotating motor is connected to one of the rotating rollers 42, thereby making this rotating roller 42 rotate, the rotating roller 42 drives the filter screen 41 to rotate, and a sponge layer 411 is arranged on the inner side of the filter screen 41, the sponge layer 411 is used to absorb the moisture in the flowing air, and a detection unit is also arranged on the base 1, the detection unit is used to detect the humidity in the battery box 2 and the temperature of the battery body, because the sand beach vehicle is used in the sand beach environment, the salt content in the air is relatively high, therefore when the humidity around the battery box 2 is too high, the contact or control parts on the battery body will be corroded, and when the temperature of the battery body is too high, the battery body will become unstable and be damaged, therefore when the detection unit detects that the humidity in the battery box 2 exceeds the set value or the temperature of the battery body exceeds the set value, the battery box 2 is closed and converted to a liquid cooling state.

[0034] In the initial state, the heat dissipation groove 21 is in the open state, at this time the battery body is cooled by air cooling, and during the driving of the ATV, air enters the battery box 2 from the front end of the battery box 2 and flows out from the rear end of the battery box 2, thereby performing air cooling and heat dissipation on the internal battery body.

[0035] Before entering the battery box 2, the air first passes through the filter screen 41, which first filters the sand in the air, and the sponge layer 411 absorbs the moisture in the air. At the same time, the rotating roller 42 drives the filter screen 41 to rotate, and the front end surface of the annular filter screen is the windward surface, so the sand accumulates on the front end surface of the filter screen. The rotating roller 42 drives the filter screen 41 to rotate, thereby changing the filter screen area on the windward surface all the time. When the filter screen with sand moves to the side surface or rear end surface of the battery box 2, the vibration force during vehicle driving will cause the sand on the filter screen to fall off, and at the same time, when it moves to the rear end surface, the gas blown out from the rear end synchronously blows the filter screen 41 outward.

[0036] Since the filter screen 41 is tightly arranged on the four rotating rollers 42, the sponge layer 411 at the rotating roller 42 is in a compressed state, so the sponge layer 411 is extruded every time it passes through the rotating roller 42, thereby extruding the moisture in the sponge layer 411 at the position, and drying the sponge layer 411. At the same time, when the sponge layer 411 passes through the rear end of the battery box 2, the heat of the battery is taken out, thereby to a certain extent, drying the sponge layer 411 that passes through the rear end.

[0037] The working principle or method of use is as follows: In the initial state, the heat dissipation groove 21 is in the open state, at this time the battery body is cooled by air cooling, and during the driving of the ATV, air enters the battery box 2 from the front end of the battery box 2 and flows out from the rear end of the battery box 2, thereby performing air cooling and heat dissipation on the internal battery body.

[0038] Before entering the battery box 2, the air first passes through the filter screen 41, which first filters the sand in the air, and the sponge layer 411 absorbs the moisture in the air. At the same time, the rotating roller 42 drives the filter screen 41 to rotate, and the front end surface of the annular filter screen is the windward surface, so the sand accumulates on the front end surface of the filter screen. The rotating roller 42 drives the filter screen 41 to rotate, thereby changing the filter screen area on the windward surface all the time. When the filter screen with sand moves to the side surface or rear end surface of the battery box 2, the vibration force during vehicle driving will cause the sand on the filter screen to fall off, and at the same time, when it moves to the rear end surface, the gas blown out from the rear end synchronously blows the filter screen 41 outward.

[0039] When the detecting unit detects that the humidity in the battery box 2 exceeds the set value or the battery body temperature exceeds the set value, the liquid cooling device is started, and the cooling mode is converted to the liquid cooling state.

[0040] After the liquid cooling device is started, the coolant can be injected from the injection port into the sealed chamber, and the flow port is provided with a pressure valve. When the pressure of the flow port reaches the set value, the flow port is opened, and the coolant circulation operation is performed.

[0041] The sealed chamber is in a deflated state in the initial state. After the coolant is injected inward, the pressure value in the sealed chamber does not reach the set value, and the flow port is not opened. At this time, the coolant remains in the sealed chamber, and the sealed chamber can expand to push the contact plate 223 to move forward and touch the side wall of the battery body. At this time, the coolant continues to be injected, the heat dissipation block 22 moves outward from the battery box 2, and finally the inclined surface at the front end of the heat dissipation block 22 touches the heat dissipation groove 21, thereby blocking the heat dissipation groove 21. At this time, the heat dissipation block 22 cannot move any more, and the battery box 2 is in a closed state.

[0042] After the battery box 2 is closed, the space inside the sealed chamber is no longer enlarged. At this time, the injection port continues to inject the coolant, thereby increasing the pressure in the sealed chamber. When the set value is reached, the flow port is opened, and the excess coolant flows back to the liquid tank through the pipeline. The pressure in the sealed chamber is maintained at the set pressure, the heat dissipation block 22 on the periphery of the battery box 2 presses the side of the battery body to prevent the battery body from deforming due to high temperature, and the contact plate 223 contacts the battery body. The cooling in the sealed chamber realizes heat exchange through the contact plate 223, thereby dissipating heat for the battery body.

[0043] Embodiment 2:

[0044] The difference between the embodiment 1 is the structure of the filter screen device 4, and the rest is the same. Referring to Figures 1-8 , the rear end of the battery box 2 and the base 1 are provided with an inclined air deflector 12, and an air outlet 11 is formed on the base 1. The air outlet 11 is located between the battery box 2 and the air deflector 12. The air deflector 12 is provided with a ventilation opening 121, and the ventilation opening is aligned with the inner wall of the filter screen 41 at the rear through a channel member. The air flowing into the battery box 2 from the ventilation opening 121 acts on the filter screen 41 to blow outward.

[0045] The air flowing out of the rear end of the battery box 2 is guided by the air deflector 12, and then flows out of the air outlet 11 on the base 1, thereby reducing the resistance of the air flowing out, so that the air at the front end of the battery box 2 can quickly enter the battery box 2.

[0046] Part of the air flow enters the channel member, so that the air can flow quickly and part of the air can blow the filter screen member 41 at the rear end.
