Description

Technical Field

[0001] This utility model relates to a downshifting energy-saving electric defroster that is related to vehicle speed. Background Technology

[0002] In the global context of advocating energy conservation, emission reduction, and sustainable development, the bus industry faces unprecedented challenges and opportunities. With increasingly stringent environmental regulations, reducing bus energy consumption and improving energy efficiency have become core objectives of bus technology research and development.

[0003] The rise of electric buses represents a significant transformation in the bus industry; however, limitations in battery technology restrict their driving range. Therefore, conserving energy at every stage of vehicle operation is crucial for improving the practicality and market competitiveness of electric buses. Various auxiliary devices in the vehicle, such as defrosters, may seem to have low power consumption, but their accumulated energy consumption over time is considerable. Furthermore, common defrosters on the market operate at high power and high airflow, resulting in high energy consumption and consuming valuable electrical resources, which contradicts the goal of low power consumption in electric buses. Therefore, reducing defroster energy consumption is an important direction for saving overall vehicle energy.

[0004] Most electric defrosters on the market are fixed-power, non-adjustable defrosters. Their core function is to use a PTC (Power Transmission Control Unit) to convert high-voltage electricity supplied by the vehicle into heat energy. A fan then transfers this heat to the windows for defrosting and defogging, and also to the driver's area for warmth. Their disadvantages include the inability to adjust the heating power based on the air outlet temperature, resulting in high outlet temperatures and discomfort; furthermore, the continuous high-power operation of the PTC wastes energy. Most electric defrosters on the market are controlled by rocker switches or rotary switches, which are inconvenient to operate; they also cannot be integrated with the air conditioning panel, taking up dashboard space. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to reduce power consumption and provide a downshifting energy-saving electric defroster that is related to vehicle speed.

[0006] To solve the above problems, this utility model is achieved through the following technical solution:

[0007] A speed-dependent downshifting energy-saving electric defroster includes an electric defroster connected to a defroster control system.

[0008] The defrost control system includes a defrost control box connected to the electric defrost, a high-voltage output control circuit, and a low-voltage output control circuit. The defrost control box is connected to the vehicle controller via the vehicle's CAN network.

[0009] The electric defroster includes an adjustable electric heater, a fan is installed on one side of the adjustable electric heater, and an air outlet duct is installed on the other side of the adjustable electric heater. The adjustable electric heater converts high-voltage electrical energy into heat energy, which is then delivered to the vehicle by the fan. The adjustable electric heater is connected to an electric heating high-voltage interface, which is connected to the vehicle's high-voltage electrical system.

[0010] The electric defroster includes a housing, within which the power-adjustable electric heater and fan are enclosed.

[0011] The casing is made of aluminum alloy with insulation board attached to the surface.

[0012] The fan is fixed to the aluminum alloy plate of the casing by hanging, with sponge or rubber pads between the fan and the aluminum alloy plate.

[0013] The fan is connected to a fresh air structure, and the fresh air structure is connected to a fresh air motor.

[0014] The adjustable power electric heater, fan wiring harness, and fresh air motor wiring harness are integrated into the defroster body wiring harness.

[0015] An air outlet temperature sensor is installed inside the air outlet duct.

[0016] Compared with existing technologies, this utility model has the following beneficial effects: This utility model provides a three-level adjustable power defroster that is linked to vehicle speed and parking time, offering energy-saving performance. Integrating an LCD touchscreen into the defroster's control system significantly improves the aesthetics of the control panel and the driver's ease of operation, enhancing the user experience. Specifically:

[0017] 1. This utility model, combined with the feedback of the air outlet temperature sensor, can realize three adjustable power levels for electric heating; at the same time, it links the fan airflow level with the PTC level to avoid the problem of excessively high air outlet temperature caused by the electric heating level being high and the fan level being low, thereby improving driver comfort.

[0018] 2. This utility model adopts a C-architecture 7-inch LCD touch screen control, which is more technologically advanced and makes it more convenient for drivers to operate.

[0019] 3. This utility model is associated with the vehicle's parking status and timer, which can reduce the defrost heater's heating power and airflow speed when the vehicle is parked (defrost ECO mode), saving vehicle energy and reducing range anxiety. Attached Figure Description

[0024] like Figure 1 As shown, a speed-dependent downshifting energy-saving electric defroster includes an electric defroster connected to a defroster control system. The electric defroster is connected to an LCD touchscreen, which in turn is connected to the defroster's electronic control box to control the electric defroster. The LCD touchscreen is also connected to the vehicle's CAN network.

[0025] The electric defroster includes an adjustable-power electric heater 3. A fan 9 is installed on one side of the adjustable-power electric heater 3, and an air outlet duct 1 is installed on the other side. The adjustable-power electric heater 3 converts high-voltage electrical energy into heat energy, which is then delivered to the vehicle interior by the fan 9. The adjustable-power electric heater 3 is connected to an electric heating high-voltage interface 4, which is connected to the vehicle's high-voltage electrical system.

[0026] Furthermore, the electric defroster includes a housing 8, within which the aforementioned adjustable-power electric heater 3 and fan 9 are enclosed. The housing 8 is made of aluminum alloy and has an insulation board attached to its surface, providing good insulation. An air outlet duct 1 is riveted to the housing 8 and connected to the bus's air duct, thereby delivering hot air into the vehicle.

[0027] Furthermore, the fan 9 is connected to a fresh air structure 10, and the fresh air structure 10 is connected to a fresh air motor 6. The fresh air structure 10 and the fresh air motor 6 together form a fresh air module, which is submerged under the bus floor and placed in the external environment; the fresh air motor 6 can control the opening and closing of the fresh air supply.

[0029] Even better, the fan 9 is fixed to the aluminum alloy plate of the housing 8 by hanging. Sponge or rubber pads are used between the fan 9 and the aluminum alloy plate to seal and reduce the resonance between the fan 9 and the sheet metal.

[0030] Furthermore, an air outlet temperature sensor 2 is installed inside the air outlet duct 1.

[0031] Furthermore, the LCD touchscreen can be a 7-inch LCD touchscreen, which transmits signals to the defrost control box to control the defrost.

The defrost control box is connected to the vehicle controller via the vehicle's CAN network. The high-voltage output control circuit outputs 600V to power the adjustable-power electric heater 3. The low-voltage output control circuit powers the fan 9, the low-voltage components of the adjustable-power electric heater 3, and the fresh air motor 6.

[0033] The above description is only a preferred embodiment of the present utility model.
