[0001] The invention relates to the technical field related to electric vehicles, and in particular to an electric vehicle engine hood that prevents snow accumulation. Background Art

[0002] With the development of science and technology and environmental protection concepts, electric vehicles have developed rapidly. Since electric vehicles are powered by electricity, unlike conventional engine-driven vehicles, the engine generates a lot of heat, which can automatically melt the snow on the hood. However, the heat output of the motor engine is very small, so it is impossible to remove the snow on the surface of electric vehicles on snowy days, which affects the weight of the vehicle and driving safety. The low output of the vehicle during driving leads to a small change in vehicle temperature, making it difficult to melt snow on other parts of the vehicle, thereby exacerbating road driving safety hazards. Summary of the invention

[0003] The object of the present invention is to provide an electric vehicle engine hood that prevents snow accumulation, so as to overcome the above-mentioned defects in the prior art.

[0009] According to a further technical solution, two control motors are symmetrically installed in the inner panel, and the control motors are dynamically connected to the rotating connection part.

[0010] According to a further technical solution, a fixing groove is provided on the outer wall of the inner embedded plate, the fixing groove is communicated with the heat flow cavity, a sealing and removable plate is detachably installed in the fixing groove, and a buckle button assembly is installed on the inner embedded plate.

[0011] Beneficial effects of the present invention:

[0012] The present invention provides an anti-snow electric vehicle engine hood with a snow melting and removal function. An airflow transmission component and an electric heating component are arranged on the engine hood. The airflow is transmitted by the airflow transmission component and then heated by the electric heating component and then outputted as a principle to achieve the snow melting and removal effect. The electric heating component is arranged in the functional snow removal device, and the output effect of the hot airflow to the front window and the engine hood is controlled by the front and rear sealing plates. At the same time, the hot airflow can be transmitted and outputted by the airflow device on the front side of the engine hood, so that the hot airflow is first outputted from the lower side of the snow accumulation plane to achieve the snow melting and loosening operation on the bottom of the snow, so as to achieve the effect of heating the contact surface between the snow and the engine board to melt and loosen the snow. After the front and rear sealing plates are opened, a large-scale hot airflow is outputted to the engine hood, so as to achieve the effect of rapid snow melting and blowing, avoiding the problem that the upper side snow is simply blown away while the hard snow at the bottom is difficult to remove and the temperature change of the engine hood surface is low, which leads to easy snow accumulation again.

[0013] The electric vehicle engine hood for preventing snow accumulation of the present invention is provided with a snow melting function. During the activation of the snow melting function, the opening and closing of the front cover plate is controlled to control the hot air flow to blow toward the front window, so that the temperature of the front window can be moderated by the hot air flow and the snow can be melted. At the same time, the hot air flow can achieve the effect of warming up the wiper gel structure, thereby avoiding the problem of the front window being scratched and affecting the field of vision due to the hard working effect of the wiper gel structure being reduced due to too low temperature. During driving, only the front cover plate can be opened to allow the hot air flow to be outputted from the plate surface airflow device 20 and the front side airflow output strip with a relatively large power, thereby avoiding the problem of snow accumulation on the surface of the engine hood plate 11 and the problem of snowflakes falling and condensing on the window surface during driving, thereby improving the driving safety effect on snowy days.

[0014] The electric vehicle engine hood that prevents snow accumulation of the present invention is provided with a snow melting function. The electric vehicle has a small heat output, resulting in a low temperature change of the vehicle body during driving, and it is impossible to ensure that the snow accumulated in other parts can be melted during driving, which poses a safety hazard. A detachable electric heating rod assembly is provided in the functional snow removal device, and a scraping rubber sleeve is provided on the surface of the electric heating rod. By removing the detachable electric heating rod and performing the snow melting operation before driving, the vehicle power structure, roof and other parts are actively melted and cleared, thereby achieving a high-efficiency solution to the driving safety hazard caused by snow accumulation on the vehicle.

The airflow output strip 22 is provided, the inner panel 17 is provided with a rotatable front side sealing plate 25, the inner panel 17 is provided with a rotatable rear side sealing plate 24, the heat flow cavity 18 is provided with an array of airflow transmission ports 23, the engine cover plate 11 is symmetrically provided with a plate surface airflow device 20 in an array, the plate surface airflow device 20 includes an inner slot plate 27, an airflow connecting cavity 28 is provided in the inner slot plate 27, the airflow connecting cavity 28 is connected with the airflow transmission port 23, and the inner slot plate 27 is symmetrically provided with an inclined output plate 29 capable of outputting airflow.

[0025] Since electric vehicles are powered by electricity, they are different from conventional engine-driven vehicles. The engine generates a lot of heat when it is running, which can automatically melt the snow on the hood. However, the heat output of the motor engine is very small, so that the snow on the surface of the electric vehicle on snowy days cannot be removed. During operation, the airflow component on the lower side of the hood plate 11 is operated to accelerate the transmission of airflow in the hood and reduce heat accumulation and dust accumulation problems. At the same time, the airflow is transmitted to the heat flow cavity 18, and the fixed electric heating rod 19 and the detachable electric heating rod 21 in the heat flow cavity 18 are activated to achieve the airflow heating effect. Initially, the rear side sealing plate 24 and the front side sealing plate 25 are in a sealed state, which increases the heating rate in the heat flow cavity 18. The airflow is mainly transmitted through the airflow transmission port 23, and the inclined output plate 29 is used to heat the hood surface on both sides to loosen the snow and partially remove the snow. As the temperature of the fixed electric heating rod 19 and the detachable electric heating rod 21 gradually rises to the threshold, the rear side sealing plate 24 and the front side sealing plate 25 are driven by the transmission component to rotate and no longer The hot flow chamber 18 is sealed so that hot air flow can be output through the air flow output strips 22 on both sides, thereby achieving the effect of melting snow on the front window and cooperating with the board air flow device 20 to achieve a continuous large-scale melting effect on the snow on the hood, thereby avoiding the problem of snow accumulation on the hood affecting power and safety during driving. During driving, the rear side sealing plate 24 can be sealed and the front side sealing plate 25 can be opened so that the air flow can be output through the board air flow device 20 and the upper air flow output strip 22, thereby achieving the effect of melting a small amount of snow on the hood. At the same time, the warm air flow blown out by the upper air flow output strip 22 can increase the temperature of the wiper to avoid the problem of the wiper freezing the colloid structure being too hard, and the problem of snow accumulation affecting the field of vision during driving on the front window can be avoided by blowing the air flow. At the same time, the detachable electric heating rod 21 can be withdrawn from the hot flow chamber 18 by buckling the sealing structure, thereby achieving the effect of thermally clearing snow from other parts of the vehicle body such as the roof cover, wheel axle structure, etc., thereby avoiding the problem of snow accumulation affecting safe driving.
