[0002] New energy vehicles (NEVs) are vehicles powered by alternative energy sources, such as electricity and hydrogen. Power batteries are a core component of electric four-wheeled vehicles, providing the vehicle with power. New energy vehicles typically use power batteries because of their high energy density, long lifespan, and low self-discharge rate.

[0003] The performance and life of power batteries depend on many factors, among which temperature has a significant impact on power batteries. In particular, the low outdoor temperature in winter can cause the following problems for power batteries:

[0004] 1. Reduced conductivity of the electrolyte: The conductivity of the electrolyte in the power battery will decrease at low temperatures, which will increase the internal resistance of the battery and thus reduce the output power of the battery;

[0005] 2. Slowed reaction rate: The working principle of power batteries is to generate electricity through chemical reactions. Low temperature will slow down the rate of these chemical reactions, thereby reducing the power output of the battery;

[0006] 3. Shortened lifespan: Working in a low temperature environment for a long time may cause the performance of the power battery to decline and shorten its lifespan.

[0007] Therefore, there is an urgent need for a device that can heat the power battery when the power battery temperature is low while the vehicle is running, so as to prevent the power battery temperature from being too low and affecting the power battery efficiency. Utility Model Content

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] The following is combined with Figure 1-3 The utility model is described in further detail.

[0025] The embodiment of the utility model discloses a wind deflector and an all-terrain vehicle.

[0026] Reference Figure 1-Figure 3 A wind deflector includes a wind deflector body 1, which is arranged on the vehicle body 8 and located on the leeward side of the fuel cell 9. The wind deflector body 1 has an air outlet 3, the windward side of the air outlet 3 circulates with the leeward side of the fuel cell 9, and the leeward side of the air outlet 3 circulates air with the power battery 10. The hot air blown out from the leeward side of the fuel cell 9 flows to the power battery 10 through the air outlet 3. When the temperature is low and the power battery 10 needs to be heated, the air outlet 3 is opened, and while the hot air flows from the rear of the vehicle, a part of the hot air flows to the power battery 10 through the air outlet 3, heating the power battery 10 and causing the battery temperature to rise. The battery has a temperature sensor, and when the battery temperature rises to a set value, the air outlet 3 is closed.

[0027] In this embodiment, an inclined plate 5 is provided at the rear end of the air deflector body 1. The inclined plate 5 is integrally formed with the air deflector body 1. The inclined plate 5 is used to separate the hot air from the rear drive device of the vehicle body 8 and to allow the rear drive device and the power battery 10 to flow. When the air outlet 3 is opened, the hot air can flow into the rear drive device through the power battery 10 to heat the rear drive device.

[0028] In other embodiments, the inclined plate 5 can also be connected to the air guide plate body 1 by a fixing method such as welding or a detachable connection method. The above-mentioned fixing method and detachable connection method are all existing technologies and are not described here one by one.

[0029] In this embodiment, the rear drive device is a rear motor 6 and a rear motor controller 7 installed at the rear of the vehicle body 8 .

[0030] In this embodiment, a guide plate 2 is provided on the deflector body 1. The guide plate 2 can be driven to rotate to open or close the air outlet 3. Specifically, the deflector body 1 is disposed in the middle of the vehicle body 8. The deflector body 1 is used to separate the hot air blown from the leeward side of the fuel cell 9 from the power battery 10 and the rear drive unit of the vehicle body 8. During operation, this can prevent the rear motor 6, rear motor controller 7, and power battery 10 from heating up and causing the rear motor 6, motor controller, and power battery 10 to overheat.

[0031] In other embodiments, the guide plate 2 can also slide to open or close the air outlet 3.

[0032] In this embodiment, a driving member 4 is provided on the air guide plate body 1, and the driving member 4 has a rotating shaft. Specifically, the driving member 4 is a motor, and the output shaft of the motor is fixedly connected to the middle part of the guide plate 2. The motor drives the guide plate 2 to rotate to open or close the air outlet 3, thereby achieving heating or insulation of the power battery 10 and the rear drive device.

[0033] In this embodiment, after the guide plate 2 is driven to rotate and the air outlet 3 is opened, an angle is formed between the guide plate 2 and the air guide plate to allow hot air to flow in, thereby changing the flow field of the hot air and allowing the hot air to heat the rear drive device and the power battery 10.

[0034] This embodiment also includes a control system. A temperature sensor is provided on the power battery 10, and the control system has a preset temperature threshold. The control system is used to control the start, stop, and forward and reverse rotation of the drive element 4. Specifically, the control system can be provided separately or utilize the vehicle's built-in vehicle controller. The temperature sensor is used to detect the temperature of the power battery 10. The temperature value detected by the temperature sensor is transmitted to the control system, which compares it with the temperature threshold. When the temperature of the power battery 10 is below the temperature threshold, the air vent 3 is opened. When it is above the temperature threshold, the air vent 3 is closed, thereby heating and insulating the power battery 10, keeping the power battery 10 within an appropriate temperature range and effectively ensuring the efficiency of the power battery 10.

[0035] According to the utility model, when the temperature is high and the power battery 10 does not need to be heated by hot air, the air vents 3 on the air guide plate are closed to separate the hot air from the power battery 10, thereby preventing the hot air circulation from heating the battery and causing failure. When the temperature is low and the power battery 10 needs to be heated, the air vents 3 are opened, and while the hot air flows toward the rear of the vehicle, a part of the hot air flows toward the power battery 10 through the air vents 3, heating the power battery 10 and causing the battery temperature to rise. The battery has a temperature sensor, and the air vents 3 are closed when the battery temperature rises to a set value.

[0036] The present invention also provides an all-terrain vehicle, which includes the above-mentioned wind deflector. Since the all-terrain vehicle adopts the above-mentioned technical solution, it has at least all the beneficial effects brought about by the technical solution of the above-mentioned embodiment, which will not be described in detail here.

[0037] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the scope of protection of the present utility model.
