[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The core of this utility model is to provide a heating and defrosting device and vehicle for radar, which can effectively solve the problems of fogging and frosting on the radar surface.

[0040] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] For details, please refer to Figures 1-5 The present invention provides a heating and defrosting device for radar, comprising: a panel 100, a heating wire 200, a diaphragm layer 300, a first metal sheet 410, and a second metal sheet 420.

[0042] In one embodiment, panel 100 is a decorative panel that serves as the outer surface of the vehicle. The decorative panel is attached to the radar to facilitate heat conduction. In another embodiment, panel 100 constitutes the radar panel, meaning that panel 100 is part of the radar and forms an integral part of the radar system as a radar panel.

[0043] The heating wire 200 is connected to the power supply via a first metal sheet 410 and a second metal sheet 420. The heating wire 200 is mounted on the panel 100 via a diaphragm layer 300. The heating wire 200, the first metal sheet 410, and the second metal sheet 420 can all be made of metal materials capable of conducting current. The first metal sheet 410 and the second metal sheet 420 form a series circuit, conducting the current from the power supply to the heating wire 200, generating heat on the heating wire 200, and ultimately achieving the heating effect.

[0044] The second metal sheet 420 is a bendable metal sheet. It can be adapted to bend into the required shape according to the actual connection situation, which is beneficial for installation and contact on the vehicle.

[0045] This solution provides a radar heating and defrosting device that utilizes a first metal sheet 410 and a second metal sheet 420 to transfer current to a heating wire 200 to generate heat. The heating wire 200 is mounted on a panel 100 via a diaphragm layer 300. The panel 100 is attached to the radar or forms part of the radar, thereby transferring the heat from the heating wire 200 to the panel 100 to achieve a heating effect, effectively solving the problems of fogging and frosting on the radar surface. Simultaneously, the second metal sheet 420 can be adapted to be bent into the desired shape, facilitating installation.

[0046] This solution also includes a control circuit board 500, which is connected between the second metal plate 420 and the power supply to convert unstable voltage into the required stable voltage, thereby ensuring the normal operation of the heating defrosting device.

[0047] This voltage conversion function is typically achieved in the following ways: 1. Using a Zener diode in the control circuit board 500 can effectively convert unstable voltage into stable voltage. 2. Introducing current negative feedback into the control circuit board 500 can improve circuit stability. The negative feedback mechanism can automatically adjust circuit parameters to offset input voltage fluctuations, thereby maintaining a stable output voltage. 3. Using power management chips (such as linear regulators and switching regulators) in the control circuit board 500 is widely used for voltage conversion and stabilization. These chips can efficiently convert unstable input voltages into stable output voltages. 4. Using filter circuits in the control circuit board 500 can remove high-frequency noise and fluctuations in the voltage, thereby improving voltage stability. Common filter components include capacitors, inductors, and resistors. 5. Adding anti-interference circuit components to the control circuit board 500 can prevent voltage instability caused by interference. These components can filter out interference pulses in the input power supply, ensuring a stable voltage supplied to the circuit board.

[0048] The control method of converting unstable voltage into the required stable voltage by the control circuit board 500 is existing technology, and its specific structure is not further limited.

[0049] Furthermore, the control circuit board 500 can be a rigid circuit board or a flexible circuit board. The second metal sheet 420 adopts the bendable metal sheet in the above specific embodiment, so that the position of the control circuit board 500 relative to the first metal sheet 410 can be changed, which can improve the convenience of installation.

[0050] Furthermore, rigid circuit boards can replace traditional flexible circuit boards. Rigid circuit boards have advantages in price and heat dissipation compared to traditional flexible circuit boards, providing better cost and heat dissipation performance. The floating voltage at the vehicle body end is converted into a stable rated voltage by the rigid circuit board. The voltage is then transferred to the heating wire 200 through the second metal sheet 420 and the first metal sheet 410, providing a stable rated current to the heating wire 200 and generating heat, ultimately achieving the heating effect.

[0051] Specifically, the second metal piece 420 can be fixed to the control circuit board 500 by soldering.

[0052] The control circuit board 500 is fixed in position by the RPS (i.e., the reference point system on the vehicle panel) on the panel 100, and then fixed to the panel 100 by heat riveting.

[0053] In a specific embodiment, the first metal sheet 410 and the second metal sheet 420 are detachably connected. During assembly, the first metal sheet 410 can be connected to the panel 100 to form a first assembly, and the second metal sheet 420 can be connected to the control circuit board 500 to form a second assembly. The first assembly and the second assembly can be assembled simultaneously and independently, and then finally assembled together.

[0054] One of the first metal sheet 410 and the second metal sheet 420 is provided with a slot, and the other is provided with a block. Pressing the block can insert it into the slot, thereby achieving the engagement of the first metal sheet 410 and the second metal sheet 420.

[0055] like Figures 3-5 As shown, the first metal sheet 410 has a slot 411, and the second metal sheet 420 has a locking block 421. The second metal sheet 420 is arranged along the height direction, and the locking block 421 at the top is engaged with the slot 411 of the first metal sheet 410 to restrict the second metal sheet 420 from moving horizontally and downward.

[0056] The first metal sheet 410 is fixed to the panel 100. Both the first metal sheet 410 and the second metal sheet 420 can be bent plates. The bending trend of the first metal sheet 410 can be adaptively designed according to the surface curvature of the panel 100 to make it fit the panel 100. The bending trend of the second metal sheet 420 can be adaptively adjusted according to the installation position of the power supply or control circuit board 500.

[0057] In order to cover as much radar area as possible, the coverage area of ​​the heating wire 200 is increased by increasing the number of the first metal sheet 410 or the second metal sheet 420.

[0058] The heating wire 200 is arranged in a roundabout manner to form a heating coil in order to increase the heating area.

[0059] For example Figure 2 and Figure 3 As shown, when there are multiple first metal sheets 410, the heating wire 200 includes multiple heating wire segments arranged side by side. Each heating wire segment is connected to each first metal sheet 410, dispersing and conducting the current to the multiple parallel first metal sheets 410 and the heating wire 200, which can also increase the heating area.

[0060] In a specific embodiment, an insulating layer is provided on the surface of the heating wire 200, which can prevent excessive oxidation of the heating wire 200 during use and avoid short circuits caused by the heating wires 200 bridging together, thereby greatly extending the service life of the heating wire 200. The insulating layer can specifically be a black paint layer.

[0061] The diaphragm layer 300 can specifically be an ink layer. The ink layer has good weather resistance, stable heating and power, and can protect the heating wire 200. The ink layer may include multiple layers, such as three ink layers, including one mold injection anti-impact ink layer to improve the temperature resistance and impact resistance of the diaphragm layer 300. In addition to eliminating the need for multiple printing, it can also ensure zero VOC emissions, meeting environmental protection requirements.

[0062] To ensure a secure installation of the heating wire 200 on the panel 100, the heating wire 200 is thermally embedded into the surface of the diaphragm layer 300 using an ultrasonic process. For example, the embedding depth of the heating wire 200 in the diaphragm layer 300 is controlled to be 2 / 3 of the diameter of the heating wire 200 to ensure the required resistance value.

[0063] The first metal sheet 410 is connected to the heating wire 200 by a soldering process, which can achieve a stable connection between the first metal sheet 410 and the heating wire 200.

[0064] The first metal sheet 410 is connected to the diaphragm layer 300 by adhesive. The adhesive can be designed for use in environments ranging from -40°C to 130°C, and the pull-out force test requires a minimum of 180N.

[0065] In a specific embodiment, the second metal sheet 420 has higher ductility than the first metal sheet 410. The flexibility of the second metal sheet 420 is mainly used to improve the ease of installation, while the structural strength of the first metal sheet 410 is used to achieve a stable connection.

[0066] The first metal sheet 410 is preferably made of copper. Copper sheets are an ideal choice for conductive applications due to their high conductivity, heat resistance, chemical stability, high strength and reliability, as well as their economy.

[0067] In addition, this utility model also provides a vehicle including a heating and defrosting device for radar as described in the above specific embodiment.

[0068] Obviously, vehicles equipped with the aforementioned radar heating and defrosting devices have the same beneficial effects, which will not be elaborated upon here.
