Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to an automotive auxiliary defrosting device, defrosting system, and vehicle. Background Technology

[0002] As living standards improve, the proportion of people buying cars has increased significantly, and more people are choosing to travel by car. Therefore, improving vehicle comfort and safety has become a focus for various companies.

[0003] In rainy or snowy weather, car windows often fog up and frost, seriously affecting driving safety. People usually choose to use the air conditioning to defrost, and in Northeast China, they also use auxiliary tools such as rubber scrapers. Traditional gasoline-powered vehicles generally rely on engine coolant temperature to heat the air. When the vehicle is cold-started, the coolant temperature is low and the warm-up rate is slow, so the defrosting process usually takes a long time. Most new energy vehicles rely on electrically heated air for defrosting. Although the warm-up rate is fast, the defrosting speed is still not ideal, greatly reducing travel efficiency.

[0004] In spring and autumn, car windows tend to fog up frequently while driving. Although the air conditioner can defog the windows, the defogging mode mostly uses cold air, which can lead to a poor passenger experience when the weather is cold. Utility Model Content

[0005] This application provides an automotive auxiliary defrosting device, a defrosting system, and a vehicle.

[0006] The technical solution adopted in this application is: an automotive auxiliary defrosting device, including a defrosting device, the defrosting device including an air outlet assembly and a heating assembly, the air outlet assembly including an air outlet with a built-in fan, the heating assembly including a heating module, the heating module being located between the air outlet and the fan, and the air outlet assembly being located on the vehicle door trim panel and / or dashboard.

[0007] The heating module includes a heating plate, the air outlet assembly includes a housing, the fan and the heating plate are disposed inside the housing, the top of the housing is provided with a cover, and the cover is provided with an air outlet communicating with the outside of the housing.

[0008] The housing is rectangular in shape, and the bottom of the housing has a plurality of through holes evenly distributed.

[0009] The air outlet is equipped with a lever, which is rotatably mounted on the air outlet.

[0010] An automotive auxiliary defrosting system is applied to the defrosting device described above, the auxiliary defrosting system including interconnected control circuits;

[0011] The control circuit includes a fan control circuit and a heating control circuit;

[0030] like Figures 1 to 2 As shown, the present application provides an automotive auxiliary defrosting device, including a defrosting device, which includes an air outlet assembly and a heating assembly. The air outlet assembly includes an air outlet 1 with a built-in fan 2, and the heating assembly includes a heating module 3 located between the air outlet 1 and the fan 2. The air outlet assembly is located on the vehicle door trim panel and / or dashboard.

[0031] This application solution involves installing an air vent assembly on the dashboard or door panel of the vehicle. The heating module 3 then heats the airflow from the air vent assembly, assisting the vehicle in defrosting and defogging. This avoids the slow heating and low defrosting efficiency that can occur when using the air conditioner alone, thus improving the user's driving experience and enhancing driving safety. Because the air vent assembly is located on the dashboard or door panel, the air outlet is closer to the windshield, facilitating rapid defrosting and defogging. By combining the air vent assembly and heating module 3 with the air conditioner, the defrosting process is accelerated without affecting the normal operation of the air conditioner.

[0032] In one embodiment, the heating module 3 includes a heating plate 31, and the air outlet assembly includes a housing 4. The housing 4 is provided with a fan 2 and a heating plate 31 inside, and the top of the housing 4 is provided with a cover 5. The cover 5 is provided with an air outlet 1 that connects the housing 4 to the outside.

[0033] The heating plate 31 is installed inside the housing 4, between the fan 2 and the air outlet 1. When the air blown out by the fan 2 flows into the air outlet 1, it can be heated by the heating plate 31 to increase the air outlet temperature at the air outlet 1, which is beneficial for rapid defrosting.

[0034] Furthermore, the housing 4 is rectangular in shape, and a plurality of through holes 41 are evenly provided on the bottom of the housing 4.

[0035] A through hole 41 is provided at the bottom of the housing 4 to facilitate heat dissipation of the fan 2, thereby ensuring that the fan 2 can be used stably for a long time and avoiding excessively high internal temperature of the housing 4 due to the heating plate 31 and the fan 2 both heating up when they are working. At the same time, it is also beneficial for air to be drawn in through the air inlet of the fan 2.

[0036] Preferably, the air outlet 1 is provided with a lever 6, which is rotatably mounted on the air outlet 1.

[0037] In this embodiment, the cover 5 is rectangular, with an opening in the middle for mounting the lever 6. The lever 6 is similar to the common type of air conditioning vent in a vehicle and is evenly distributed on the cover 5. The air direction and air volume can be adjusted by rotating the lever 6.

[0038] like Figure 2 As shown, this application also provides an automotive auxiliary defrosting system, applied to the aforementioned defrosting device, the auxiliary defrosting system including interconnected control circuits;

[0039] The control circuit includes a fan 2 control circuit and a heating control circuit;

[0040] The fan 2 control circuit is equipped with a fan 2; the heating control circuit is equipped with a heating module 3, and the fan 2 control circuit and the heating control circuit are connected in parallel.

[0041] In one embodiment, the auxiliary defrosting system includes a defogging mode and a defrosting mode. The defogging mode is configured to activate the fan 2 control circuit, and the defrosting mode is configured to activate both the fan 2 control circuit and the heating control circuit.

[0042] In defogging mode, heating module 3 is not required; only fan 2 needs to blow air onto the glass to assist in defogging. In defrosting mode, hot air is required for defrosting; heating module 3 heats the air outlet of fan 2 to accelerate the defrosting process.

[0043] Furthermore, the defrosting system also includes control switches, comprising a first switch 7 located in the fan 2 control circuit and a second switch 8 located in the heating control circuit. In demisting mode, the first switch 7 is closed and the second switch 8 is open; in defrosting mode, both the first switch 7 and the second switch 8 are closed. It is understood that... Figure 2 In the circuit, S1 is the first switch 7, S2 is the second switch 8, FU is a fuse, FR is a thermal relay, and FR serves as the temperature control switch 9 to protect the circuit from overheating.

[0044] When defrosting is required, both the first switch 7 and the second switch 8 are closed, connecting the fan 2 control circuit and the heating control circuit, supplying power to the fan 2 and the heating module 3, so that the heating module 3 heats the air from the fan 2 and blows it out from the air outlet 1.

[0045] When defogging is required, the first control switch 7 is closed to connect the control circuit of the fan 2. There is no need to heat the air outlet, and the fan 2 can directly output air from the air outlet 1.

[0046] Understandably, the heating plate 31 is equipped with multiple spiral heating wires. The fan 2 delivers air to the heating plate 31. The air passes through the spiral heating wires. The heat generated by the heating wires after they are energized exchanges heat with the passing cold air. When the airflow reaches the air outlet 1, the temperature rises, which helps to defrost.

[0047] Preferably, the control switch further includes a temperature control switch 9, which is disposed in the heating control circuit and is configured to disconnect when the temperature is higher than a preset temperature.

[0048] A temperature control switch 9 is set in the heating control circuit. The temperature control switch 9 monitors the ambient temperature and automatically cuts off when the temperature exceeds the preset value to prevent damage to the air outlet component and heating component due to excessive temperature. It also prevents components from burning out due to excessive temperature, which is beneficial for component maintenance and ensures the safety of drivers and passengers.

[0049] A vehicle is provided with a battery and a defrosting system as described above, with a control circuit connected to the battery. In this configuration, the battery can directly supply power. This helps reduce the electricity consumption of new energy vehicles when using air conditioning for defrosting, thus increasing the vehicle's driving range.

[0050] In one embodiment, the vehicle has a door panel with a cigarette lighter located thereon, and the control circuit is connected to the circuit of the cigarette lighter.

[0051] When a cigarette lighter is installed in a vehicle, the cigarette lighter is directly connected to the battery, and the control circuit is connected to the cigarette lighter circuit. The battery provides indirect power, which reduces assembly costs, facilitates the rational layout of connection lines, and shortens the length of the control circuit lines.

[0052] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0053] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0054] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
