[0043] The utility model discloses a snow removal device, which is used to remove snow from vehicle window glass to ensure the driver's field of vision. In addition, the utility model also discloses a vehicle with the snow removal device.

[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] In some areas, when the outdoor temperature is low, snow may occur, which may affect the driver's vision.

[0047] When it snows and the vehicle is in motion, the driver usually turns on the windshield wipers to clear the snow from the vehicle's glass. Figures 1 to 3 Take the falling snow on the front windshield as an example to illustrate the problem of snow accumulation. Figure 1 It is a schematic diagram of the structure of a vehicle disclosed in an embodiment of the utility model, Figure 2 Schematic diagram of the partial structure of the vehicle window glass disclosed in the embodiment of the utility model. Figure 3 It is a schematic diagram of the partial structure of the window glass of a vehicle with a snow accumulation area disclosed in an embodiment of the utility model.

[0048] like Figure 1As shown, the vehicle generally comprises: a front window glass 100, an A-pillar 200 and a windshield wiper 300. The front window glass 100 is connected to an A-pillar 200 on both sides, thereby forming a front windshield structure of the vehicle. The windshield wiper 300 is generally two, one end of which is hinged to the vehicle body, and the other end is attached to the front window glass 100 and can rotate around the hinge point, thereby forming a fan-shaped cleaning surface on the front window glass 100.

[0049] Combination Figure 2 It can be seen that the cleaning surface of the wiper 300 on the front window glass 100 is a 1 / 4 arc surface. When the wiper 300 cleans the snow on the front window glass 100, the wiper 300 will clean the snow on the front window glass 100 to the lower side and the side of the front window glass 100.

[0050] If the outdoor temperature is low, the snow cannot melt, and the falling snow will gradually accumulate on the side of the vehicle window glass, so that snow accumulates on the side of the front window glass 100. Figure 3 As shown, a snow accumulation area 101 is formed beside the vehicle window. The snow in the snow accumulation area 101 will affect the driver's field of vision; in addition, since the side of the front window glass is close to the A-pillar, the snow accumulation will cause a larger visual blind spot. During the vehicle's left turn or U-turn, the driver cannot see the traffic conditions in the blind spot due to the snow accumulation, which will cause a safety hazard and cause a traffic accident.

[0051] Based on the above problems, Figures 4 to 6 As shown, the present application discloses a snow removal device, which can clear the snow on the vehicle window glass, especially the snow in the snow accumulation area 101. Figures 4 to 6 Schematic diagrams of different structures of the snow removal device disclosed in this application.

[0052] Figures 4 to 6 The snow removal device shown in the figure includes: a post-processor 5, a washing pot 3 and a heat exchange component 7.

[0053] The inlet of the post-processor 5 is communicated with the exhaust gas outlet of the engine 2, and the outlet of the post-processor 5 is communicated with the exhaust pipe of the vehicle.

[0054] It should be noted that the post-processor 5 refers to a device for processing and purifying engine exhaust emissions. It is located between the engine and the exhaust pipe, and converts the emitted harmful substances into substances that are more friendly to the environment and human health through a series of chemical reactions. The types of engine post-processors include but are not limited to SCR (selective catalytic reduction) systems, DOC (oxidation reduction catalyst) systems, and DPF (particulate filter) systems.

[0055] It can be understood that the snow removal device in the present application utilizes the exhaust gas processed by the after-processor 5 of the vehicle.

[0056] The washing pot 3 is used to spray cleaning agent onto the vehicle window glass. The shape and size of the washing pot 3 can be set according to different needs. The washing pot 3 can be a structure for the vehicle to hold cleaning agent, and the cleaning agent includes but is not limited to glass water.

[0057] The heat exchange component 7 is connected between the post-processor 5 and the exhaust pipe, and is used to introduce the high-temperature gas in the post-processor 5 into the heat exchange component 7; the heat exchange component 7 exchanges heat with the washing pot 3 to heat the cleaning agent in the washing pot 3.

[0058] In combination with the above analysis, the snow removal device in the present application introduces the high-temperature gas in the post-processor 5 into the heat exchange component 7, and heats the cleaning agent in the washing pot 3, so that the cleaning agent sprayed from the washing pot 3 to the vehicle window glass is a high-temperature liquid, and the heated cleaning agent is sprayed onto the vehicle window glass. During the swinging process of the wiper, the fallen snow and the cleaning agent will be cleaned to the snow accumulation area 101 beside the vehicle window glass. Under the action of the high-temperature cleaning agent, the accumulated snow will gradually melt, and under the action of the gravity of the snow water, the accumulated snow will slide down, realizing the snow removal of the snow accumulation area 101 of the vehicle window glass, thereby ensuring the driver's field of vision and avoiding the occurrence of traffic accidents caused by obstructed vision.

[0059] The heat exchange assembly 7 in some embodiments includes a heat exchanger 73 , a connecting pipe 72 and a switch valve 71 .

[0060] The heat exchanger 73 is connected between the post-processor 5 and the exhaust pipe through the connecting pipe 72, and the heat exchanger 73 can exchange heat with the washing pot 3. The switch valve 71 is arranged on the connecting pipe 72 and is used to control the connection and disconnection of the connecting pipe 72.

[0061] The heat exchange component 7 includes a heat exchanger 73, which is connected to the output end of the post-processor 5 and can be used to divert the high-temperature gas in the post-processor 5. The high-temperature gas enters the heat exchanger 73 through the connecting pipe 72 and exchanges heat with the heat exchanger 73, so that the temperature at the heat exchanger 73 increases; on the other hand, the heat exchanger 73 can exchange heat with the washing pot 3, thereby heating the cleaning liquid in the washing pot 3.

[0062] The heat exchanger 73 in the present application adopts a contact heat exchange method with the washing pot 3, and the heat exchanger 73 does not need to be connected to the washing pot 3, thereby ensuring the cleanliness of the cleaning liquid in the washing pot 3 and preventing the cleaning liquid from failing to meet the cleaning requirements; in addition, it can also prevent the reduction of the heat exchange medium in the heat exchanger 73.

[0063] The switch valve 71 can be set to shut off the connecting pipe 72 when snow removal is not needed, thereby avoiding energy loss and preventing the washing pot 3 from being overheated and affecting its service life.

[0064] The heat exchanger 73 in some embodiments is a gas-liquid thermal coupling heat exchanger. Specifically, the gas in the post-processor 5 enters the heat exchanger 73 through the connecting pipeline and exchanges heat with the liquid heat-conducting medium in the heat exchanger 73. It can be understood that when the gas flows in the heat exchanger 73, the heat therein will be transferred to the liquid heat-conducting medium, so that its temperature increases; and the liquid heat-conducting medium will transfer the heat therein to the gas, so that its temperature decreases.

[0065] like Figure 7 As shown, the heat exchanger 73 in the present application includes but is not limited to being wound around the washing pot 3 to increase the contact area between the heat exchanger 73 and the washing pot 3.

[0066] In some embodiments, the heat exchanger 73 may be attached to the washing pot 3 near the outlet to increase the temperature of the detergent at the outlet of the washing pot 3. The shape and connection mode of the heat exchanger 73 may be set according to different needs and are within the protection range.

[0067] Liquid heat-conducting media include but are not limited to water, glycerin, methyl silicone oil, phenyl silicone oil, etc.

[0068] In some embodiments, the heat exchanger 73 may also be a gas heat exchanger, that is, the medium in the heat exchanger is gas.

[0069] In some embodiments, the switch valve 71 is a multi-opening electromagnetic valve. Using the electromagnetic valve to control the connecting pipeline 72 can help increase the amount of gas entering the heat exchanger 73, thereby changing the heat exchange temperature between the heat exchanger 73 and the gas, thereby affecting the temperature of the washing pot 3 and changing the temperature of the sprayed cleaning liquid.

[0070] Figure 5 and Figure 6 The snow removal device for the vehicle further includes an electronic control unit 4 , which is connected to the switch valve 71 and is used to control the opening degree of the switch valve 71 .

[0071] Regarding the control of the electronic control unit 4, in some embodiments, manual control may be selected, for example, an operation button may be provided inside the vehicle or an operation key may be provided on the control screen.

[0072] The cost is lower by manual control.

[0073] In some embodiments, a temperature sensor (not shown in the figure) for detecting the temperature of snow may be provided in the snow accumulation area 101 near the edge of the vehicle window glass, and the temperature sensor is connected to the electronic control unit 4 .

[0074] When the vehicle is driving in snowy weather, if the temperature sensor detects that the temperature of the snow accumulation area 101 is lower than a first preset value, the electronic control unit 4 controls the switch valve 71 to be fully opened; if the temperature sensor detects that the temperature of the snow accumulation area 101 is higher than a second preset value, the electronic control unit 4 controls the switch valve 71 to be closed.

[0075] The second preset value is higher than the first preset value. The specific values ​​of the first preset value and the second preset value can be set according to different needs and are both within the protection range.

[0076] When the temperature sensor detects that the temperature of the snow accumulation area 101 is between the first preset value and the second preset value, the electronic control unit 4 controls the proportional opening of the switch valve 71. For example, the first preset value is -10°C, the second preset value is -2°C, and when the temperature sensor detects that the temperature of the snow accumulation area 101 is -4°C, the opening of the switch valve 71 is 1 / 3; when the temperature sensor detects that the temperature of the snow accumulation area 101 is -6°C, the opening of the switch valve 71 is 1 / 2; when the temperature sensor detects that the temperature of the snow accumulation area 101 is -8°C, the opening of the switch valve 71 is 2 / 3.

[0077] Combination Figures 4 to 6 As shown, a muffler 6 is provided between the exhaust pipe and the after-processor 5 , and a heat exchange component 7 is connected between the after-processor 5 and the muffler 6 .

[0078] It should be noted that the connection method between the muffler 6 and the exhaust pipe can be set according to different needs.

[0079] Combination Figure 6 As shown, the engine in some embodiments may be a turbocharged engine. Figure 6 The turbocharged engine in the embodiment includes a turbocharger 21 , an engine body 23 and an intercooler 22 .

[0080] The turbocharger 21 includes a turbine 212 and a compressor 211. The air inlet of the compressor 211 is connected to the outlet of the air filter 1, the exhaust port of the compressor 211 is connected to the air inlet pipe of the intercooler 22, the air outlet pipe of the intercooler 22 is connected to the air inlet manifold of the engine body 23; the exhaust manifold of the engine body 23 is connected to the air inlet of the turbine 212, and the exhaust port of the turbine 212 is connected to the exhaust pipe.

[0081] During the snow removal process, in the present application, the high-temperature gas in the post-processor 5 is diverted, and heat exchange is performed on the heating medium in the heat exchanger 73. The heat exchanger 73 then exchanges heat with the washing pot 3, so that the cleaning fluid in the washing pot 3 is heated, and the cleaning fluid sprayed on the vehicle window glass is a high-temperature liquid. During the swinging process of the wiper 300, the glass water is pushed to the snow accumulation area 101, and the snow in the snow accumulation area 101 is heated to form a solid-liquid mixture, which is separated from the snow accumulation area 101 under the action of gravity, thereby achieving the purpose of snow removal.

[0082] In addition, the present application also discloses a vehicle, including a snow removal device, wherein the snow removal device is the snow removal device disclosed in the above-mentioned embodiment. Therefore, the vehicle with the snow removal device also has all the above-mentioned technical effects, which will not be described one by one here.

[0083] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0084] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
