Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a de-icing and snow removal system, vehicle, and method for the outer side of a car's windshield. Background Technology

[0002] In harsh winter conditions, when vehicles are parked for extended periods or exposed to freezing rain, their windshields are prone to icing, causing inconvenience and safety hazards for drivers. Traditional methods include using a scraper to forcibly remove the ice or turning on the car's heater to defrost the windshield. However, these traditional methods have several problems. Forcibly removing ice with a scraper requires prolonged operation in low temperatures, and the hard ice layer is difficult to remove, potentially causing scratches and damage to the glass surface. Authorized publication number CN108001420B discloses a windshield de-icing device for automobiles. This solution uses a scraper to remove ice from the windshield, an air blowing device to improve scraping efficiency, and a buffer device to make de-icing safer. While this solution utilizes a mechanical structure for automatic de-icing, it still relies on scraping. When the temperature is low and the ice on the windshield is hard, the above de-icing method is not ideal and cannot quickly and effectively remove the ice.

[0003] In addition, some drivers choose to turn on the car's heater to defrost the windshield. While this method is convenient and does not require the driver to operate it outside the car for an extended period of time, the heating effect of the car's heater on the outer side of the windshield is limited. Furthermore, when the outside temperature is low, using the car's heater to defrost the windshield requires the driver to wait inside the car for a considerable amount of time, which affects travel efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a de-icing system, vehicle and method for the outer side of the windshield of an automobile. Compared with the commonly used method of scraping and de-icing combined with heating and blowing by a heater, it reduces the difficulty of removing hard ice blocks, not only shortens the time to melt the ice and snow on the windshield, but also recovers and reuses the lost heat energy.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] Firstly, a de-icing and snow removal system for the outer side of a car windshield includes:

[0007] A bag assembly, including a bag, for attaching to and sliding on glass to achieve de-icing;

[0008] The container assembly contains heat exchange fluid;

[0009] The first circulation pipeline connects the container assembly and the bladder, serving as a circulation loop for the heat exchange medium.

[0010] The second circulation pipeline includes a wound tube wrapped around the periphery of the container assembly, with two open ends connected to the engine cooling pipeline. The high-temperature cooling medium inside the engine heats the heat exchange fluid through the second circulation pipeline. The heated heat exchange fluid flows through the bag, which is used to attach to the windshield and move horizontally to melt ice and snow.

[0011] The waste heat emitted by the car engine cooling system exchanges heat with the heat exchange fluid in the container assembly. The heated heat exchange fluid enters the bag through the first circulation pipe to melt the ice and snow on the windshield. Compared with the commonly used method of scraping ice and blowing it with a heater, this method reduces the difficulty of removing hard ice blocks, shortens the time to melt the ice and snow on the windshield, and also recovers and reuses the lost heat energy.

[0012] As a further implementation, the first circulation pipeline includes a bag inlet pipeline and a bag outlet pipeline connecting the container assembly and the bag, and a booster circulation pump is provided on the bag inlet pipeline; the first circulation pipeline is made of flexible corrugated pipe.

[0013] As a further implementation, a first control valve is provided on the water inlet pipe of the bladder, and both the first control valve and the booster circulation pump are connected to a controller.

[0014] As a further implementation, the second circulation pipeline includes a first heat exchange pipeline and a second heat exchange pipeline, the first heat exchange pipeline connecting the winding pipeline and the engine cooling water outlet pipeline, and the second heat exchange pipeline connecting the winding pipeline and the engine cooling water inlet pipeline.

[0015] As a further implementation, the first heat exchange pipeline is equipped with a circulation pump and a first temperature sensor, and a flow divider valve is provided at the end near the engine. The second heat exchange pipeline is equipped with a second control valve, and the controller is connected to the first temperature sensor, the circulation pump, the flow divider valve, and the second control valve.

[0016] As a further implementation, the contact surface between the wound pipe and the container assembly is a planar structure, the cross-section of the wound pipe is rectangular or triangular, and a heat exchange structure is provided inside the wound pipe.

[0017] As a further implementation, the container assembly includes a second temperature sensor and a heater, which are connected to a controller.

[0018] As a further implementation, the pouch assembly includes a pouch mounting plate, with a pouch on one side of the pouch mounting plate, a silicone scraper on one side of the pouch mounting plate, and a handle on the other side, the handle connecting the first circulation pipeline and the pouch.

[0019] Secondly, a vehicle equipped with an ice and snow removal system for the outer side of the windshield as described above, with the bag located at the windshield trim panel.

[0020] Thirdly, a method for de-icing and snow removal on the outside of a car windshield, employing any of the de-icing and snow removal systems described above, includes the following steps: the car engine is started, and the high-temperature cooling medium in the engine flows through the second circulation pipe and the winding pipe to heat the heat exchange fluid in the container assembly. After the heat exchange fluid reaches the set temperature, the controller opens the first control valve and the booster circulation pump, and the heat exchange fluid flows through the bag. The bag is attached to the windshield and moves horizontally to melt the ice and snow. When the temperature inside the container assembly does not reach the set temperature, the controller turns on the heater to assist in heating the heat exchange fluid.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. This invention utilizes the waste heat emitted by the automotive engine cooling system to exchange heat with the heat exchange fluid in the container assembly. The heated heat exchange fluid enters the bag through the first circulation pipeline to melt the ice and snow on the windshield. Compared with the commonly used method of scraping ice and using a heater to blow air, this method reduces the difficulty of removing hard ice blocks, shortens the time of melting ice and snow on the windshield, and also recovers and reuses the lost heat energy.

[0023] 2. The container assembly of the present invention is provided with a second temperature sensor and a heater. The second temperature sensor can detect the temperature of the heat exchange fluid in real time. After the specified temperature is reached, the first circulation pipeline is opened to realize the de-icing and snow removal work. When the temperature of the heat exchange fluid fails to reach the specified temperature for a long time, the heater can assist in heating.

[0024] 3. The spiral wound pipe of the present invention is provided with a heat exchange structure to improve heat exchange efficiency; and the contact surface between the spiral wound pipe and the container assembly is a planar structure, and the cross-section of the spiral wound pipe is rectangular or triangular, further improving heat exchange efficiency.

[0025] 4. This invention utilizes the contact between the bag and the ice and snow on the car window to quickly melt the ice and snow or rapidly reduce the hardness of the ice. Then, combined with the silicone scraper on the side of the bag, the ice can be quickly removed, improving the efficiency of de-icing and snow removal and ensuring the driver's travel experience.

[0037] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0038] Example 1

[0039] In a typical embodiment of the present invention, reference is made to Figure 1-2As shown, a de-icing and snow removal system for the outer side of a car windshield includes a bag assembly 10, a container assembly 30, a first circulation pipe 40, and a second circulation pipe 50. The container assembly 30 contains a heat exchange fluid, and the bag assembly includes a movable bag 11. The first circulation pipe connects the container assembly 30 and the bag, serving as a circulation loop for the heat exchange medium. The second circulation pipe includes a wound pipe 50.3 wrapped around the container assembly 30 at its center. The two open ends of the second circulation pipe 50 are connected to engine cooling pipes. The high-temperature cooling medium in the engine heats the heat exchange fluid through the second circulation pipe. The heated heat exchange fluid flows through the bag 11, and the bag 11 can be manually moved to adhere to the windshield for rapid melting of ice and snow.

[0040] like Figure 1 As shown, the heat source in this embodiment utilizes the engine cooling system's branch piping, which includes an engine cooling water outlet pipe 100.1 and an engine cooling water inlet pipe 100.2. The engine cooling water outlet pipe 100.1 serves as the outlet pipe for the high-temperature cooling medium within the engine, while the engine cooling water inlet pipe 100.2 serves as the inlet pipe for the high-temperature cooling medium after heat exchange within the engine.

[0041] The second circulation pipeline 50 is in the form of three sections, including a first heat exchange pipeline 50.1, a spiral pipeline 50.3, and a second heat exchange pipeline 50.2 connected in sequence. The end of the first heat exchange pipeline 50.1 away from the spiral pipeline 50.3 is connected to the engine cooling water outlet pipeline 100.1, and the end of the second heat exchange pipeline 50.2 away from the spiral pipeline 50.3 is connected to the engine cooling water inlet pipeline 100.2.

[0042] The high-temperature cooling medium inside the engine is discharged through the engine cooling water outlet pipe 100.1, and then passes through the first heat exchange pipe 50.1, the winding pipe 50.3, and the second heat exchange pipe 50.2 in sequence before returning to the engine through the engine cooling water inlet pipe 100.2.

[0043] Specifically, the winding pipe 50.3 is evenly wound around the periphery of the container assembly 30, with several turns along the axial direction of the container assembly 30, and the turns are in close contact. When the high-temperature cooling medium in the engine passes through the winding pipe 50.3, it exchanges heat with the heat exchange fluid in the container assembly 30, thereby heating the heat exchange fluid. After being heated to a specified temperature, the heat exchange fluid can circulate between the bag 11 and the container assembly 30 through the first circulation pipe 40. The bag 11 can be used to quickly de-ice and snow the windshield of the car.

[0044] like Figure 1As shown, the first circulation pipeline 40 includes a bag inlet pipeline 40.1 and a bag outlet pipeline 40.2. Both the bag inlet pipeline 40.1 and the bag outlet pipeline 40.2 are connected between the container assembly and the bag, realizing the circulation of heat exchange fluid between the container assembly 30, the first circulation pipeline 40, and the bag 11. The heat exchange fluid heated in the container assembly 30 flows through the bag inlet pipeline 40.1 through the bag 11 to heat the ice and snow on the windshield of the car that the bag 11 contacts. The cooled heat exchange fluid returns to the container assembly 30 through the bag outlet pipeline 40.2 for heat exchange and reheating, thus achieving circulation.

[0045] like Figure 2 As shown, the pouch assembly 10 includes a pouch mounting plate 13. A pouch support 12 is provided on one edge of the pouch mounting plate 13. The pouch support 12 is annular, and a pouch 11 is disposed in the groove formed by the pouch support 12 and the pouch mounting plate 13. The pouch 11 is fixedly connected to the pouch mounting plate 13. The pouch support 12 is used to restrict the edge of the pouch 11. A silicone scraper 14 is provided on the outer side of the pouch support 12, and a handle 20 is also provided on the outer side of the pouch support 12. The handle 20 and the silicone scraper 14 are located on opposite sides of the pouch support 12, and the handle connects to the first circulation tube and the pouch. Alternatively, in other examples, the first circulation tube passes through the pouch support 12 and connects to the pouch strap 11. The handle is fixed to the outer side of the pouch support 12 and sleeved on the first circulation tube 40.

[0046] When the heat exchange fluid circulates between the container assembly 30 and the bag 11, the bag assembly can be moved by the handle 20, pressing the bag against the car glass and sliding it to achieve rapid melting of ice and snow.

[0047] like Figure 1 As shown, in order to effectively control the operation of the system, a first control valve 70 is provided on the end of the bag inlet pipe 40.1 near the container assembly 30. The first control valve 70 is a flow valve used to control the loop flow on the first circulation pipe 40. A booster circulation pump 120 is also provided on the bag inlet pipe 40.1 to provide power for the heat exchange fluid and realize the circulation of the heat exchange fluid in the first circulation pipe.

[0048] It is understandable that, in this embodiment, considering that the first circulation pipeline 40 has the function of carrying steam and guiding liquid flow, and has a certain impact on the temperature and uniformity of high-temperature liquids, the first circulation pipeline 40 is made of flexible corrugated pipe, which has the advantages of high temperature resistance and acid and alkali resistance. Generally, corrugated flexible hoses are selected for devices with high fluid pressure. This pipeline serves as a transfer channel for high-temperature fluids and low-temperature fluids.

[0049] like Figure 1In order to realize the circulation between the container assembly 30 and the engine cooling system, a diversion valve 90 is provided at one end of the first heat exchange pipeline near the engine cooling water outlet pipeline 100.1. When the diversion valve 90 is opened, the connection between the container assembly 30 and the engine cooling system can be realized.

[0050] The first heat exchange pipeline 50.1 is equipped with a circulation pump 130 and a first temperature sensor 60. The circulation pump 130 is located between the first temperature sensor 60 and the diverter valve 90. The circulation pump 130 is used to provide circulation power, and the first temperature sensor 60 is used to detect the temperature of the high-temperature medium on the second circulation pipeline 50.

[0051] A second control valve 80 is provided on the second heat exchange pipeline 50.2 of the second circulation pipeline 50. The second control valve 80 is also a flow valve and has the same function as the first control valve 70.

[0052] The main structure of the container assembly 30 is a water tank structure, with an inlet 150 at the top and an outlet 140 at the bottom, used for replacing or adding the internal heat exchange fluid and periodically discharging heat exchange medium containing impurities. The container assembly contains a second temperature sensor and a heater. The second temperature sensor detects the temperature of the heat exchange fluid; when the temperature reaches the set temperature, the first circulation pipe 40 is opened, and the heat exchange fluid begins to circulate. The heater is turned on or off based on the temperature of the liquid in the water tank obtained from the first temperature sensor 60. If the temperature of the heat exchange fluid inside the container assembly 30 fails to reach the specified temperature for an extended period, the heater can be activated for auxiliary heating.

[0053] The windshield de-icing system also includes a controller 110, which is connected to a first control valve 70, a booster pump 120, a first temperature sensor 60, a second temperature sensor, a second control valve 80, a flow divider valve 90, a circulation pump 130, and a heater. By controlling the switching and operation of each component through the controller 110, rapid de-icing can be achieved.

[0054] In an alternative example, the pouch 11 is made of a soft yet strong material, such as rubber or a special polymer material. Such a material ensures that the pouch 11 has a degree of flexibility and adaptability to accommodate different shapes of windshield surfaces. When filled with liquid, the pouch 11 has a roughly rectangular parallelepiped structure.

[0055] The water tank stores a high-temperature liquid with some antifreeze properties. The second circulation pipe, acting as a heat transfer pipe, connects to the cooling pipe branch of the car engine. The spiral pipe 50.3 is wound around the water tank in a circular shape, initially designed with more than 20 layers, with a cross-section resembling a rectangle or triangle to increase the heat conduction area. The high-temperature cooling medium in the second circulation pipe 50, using the waste heat carried from the engine, flows through the spiral pipe 50.3 to the water tank, thereby raising the temperature of the liquid in the water tank. When the second temperature sensor detects that the temperature has reached the predetermined range of 45°C, the first control valve 70 opens, and the booster circulation pump 120 pressurizes and delivers the liquid into the bag. The operator uses the handle 20 to move the bag 11 evenly and orderly towards the windshield, gradually melting the snow and ice on the glass.

[0056] In other examples, after a suitable amount of high-temperature liquid is injected into the bladder 11, the first control valve 70 and the second control valve 80 are closed. At this time, the bladder 11 is used to melt ice and snow. When the temperature of the liquid in the bladder 11 decreases, the first control valve opens, and the high-temperature liquid in the water tank enters the bladder 11, while the low-temperature liquid in the bladder 11 returns to the water tank. When the temperature of the heat exchange fluid in the water tank is lower than the lower limit, the second control valve 80 opens, and the high-temperature medium at the engine end continues to heat the heat exchange fluid.

[0057] To improve the heat exchange efficiency between the high-temperature medium from the engine and the fluid in the water tank in the spiral wound pipe, a heat exchange structure is installed inside the spiral wound pipe. This structure can be heat exchange fins to increase the heat exchange area. The second circulation pipe is dedicated to providing the waste heat from the vehicle engine for this de-icing system.

[0058] To further improve heat exchange efficiency, the contact surface between the wound pipe and the container assembly is planar, and the cross-section of the wound pipe is rectangular or triangular to increase the contact area between the wound pipe and the outer surface of the container assembly.

[0059] To further control the flow rate and velocity of the high-temperature medium in the engine's high-temperature cooling system's branch pipes, a diversion valve 90 is installed. When the diversion valve 90 is open, the high-temperature medium can be diverted from the engine cooling system pipes into the second circulation pipe. By controlling the opening degree of the diversion valve 90, the flow rate and velocity of the high-temperature medium in the second circulation pipe 50 are controlled. When the diversion valve 90 is closed, the medium cannot enter the second circulation pipe 50, thus fully utilizing the heat energy generated by the vehicle engine during operation and reducing heat loss to achieve energy conservation. The controller 110 automatically controls the operating state of the diversion valve 90.

[0060] It is understandable that the heat exchange fluid in the water tank can be water, or a fluid with a specific heat capacity greater than that of water, such as thermally conductive silicone oil.

[0061] During actual de-icing, the bag is slidable 11 by the handle 20 and used in conjunction with the silicone scraper 14 as needed. After the ice and snow are heated and their hardness is reduced, the scraper can quickly remove the ice and snow. The scraper is made of a soft but strong material, such as silicone or a special polymer material, to adapt to different shapes of the windshield surface.

[0062] This embodiment utilizes the waste heat emitted by the car engine cooling system to melt the ice and snow on the windshield. Compared with the commonly used method of scraping ice and using a heater to blow air, it reduces the difficulty of removing hard ice blocks, not only shortening the time to melt the ice and snow on the windshield, but also recovering and utilizing the lost heat energy.

[0063] This embodiment combines heat conduction and heat transfer techniques to effectively utilize and solve practical problems by minimizing the ineffective loss of heat energy. Based on this system, researchers can design more intelligent and innovative new products. After the diversion valve is closed, the high-temperature medium in the engine cooling system piping can flow to other paths to participate in new operations.

[0064] Example 2

[0065] In a typical embodiment of the present invention, reference is made to Figure 3 As shown, a vehicle is equipped with the windshield de-icing and snow removal system described in Embodiment 1 above, wherein a bag is disposed at the windshield trim panel 160. When de-icing and snow removal of the windshield is required, the engine is started, and after the heat exchange fluid temperature reaches the specified temperature, the heat exchange fluid enters the bag. The bag is then manually pulled out to remove the ice and snow from the glass.

[0066] like Figure 4 As shown, when not in use, the pouch assembly 10 is placed in a suitable position on the front windshield trim panel 160 assembly. The specific location needs to be determined according to the overall layout environment of the front cabin exterior trim system of different models. A recessed step design is made on the trim panel to form a placement slot 161 that matches the shape of the pouch. A first magnetic 162 is arranged around the lower surface of the slot 161, which can be a magnetic strip.

[0067] Meanwhile, a second magnetic 15 is arranged at the edge of the bottom surface of the bag support 12 of the bag assembly. When the bag assembly 10 is not in use, the second magnetic 15 and the first magnetic 162 of the bag support 12 are attracted together.

[0068] Example 3

[0069] In a typical embodiment of the present invention, reference is made to Figures 1-3 As shown, a method for de-icing the outside of a car windshield, using the ice and snow system of Example 1, includes the following steps:

[0070] When the car starts its engine, the controller opens the diversion valve, circulation pump 130, and second control valve 80. The high-temperature cooling medium inside the engine flows through the second circulation pipe and the winding pipe to heat the heat exchange fluid in the container assembly. When the second temperature sensor detects that the heat exchange fluid has reached the set temperature, it sends feedback to the controller. The controller then opens the first control valve 70 and the booster circulation pump 120. The heat exchange fluid flows through the bag, and a person holds the handle to move the bag against the windshield to melt the ice and snow. If the temperature inside the container assembly fails to reach the set temperature for an extended period, the controller can activate the heater to assist in heating the heat exchange fluid.

[0071] This embodiment provides a better solution for de-icing vehicle windshields in harsh winter low-temperature environments, which will greatly improve the driver's driving experience and sense of security.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
