Description

Technical Field

[0001] The utility model relates to the technical field of electric heating devices, in particular to an electric heating device for vehicles. Background Art

[0002] During the use of vehicles, some target areas that need to be heated in the vehicle often need to be heated due to low temperature, ice, snow, freezing rain, or severe weather with large temperature and humidity differences inside and outside the vehicle. Therefore, an electric heating device is required to heat the target areas that need to be heated in the vehicle to ensure that the target areas that need to be heated during the use of the vehicle can quickly reach the temperature for defrosting, defogging, and removing water droplets. For example, if there is ice or water mist on the glass of the vehicle, it will affect the line of sight and data transmission of the camera infrared sensor and lidar. The target area that needs to be heated on the glass side of the vehicle is heated by an electric heating device, and obstacles on the glass side (frost, fog, water droplets, etc.) are removed during the heating process to ensure that the vehicle has a clear line of sight during use.

[0003] At present, there are two ways to use electric heating devices for heating target areas that need to be heated in vehicles. One is that when heating is needed, the driver turns on the electric heating device installed on the vehicle for heating, and after the electric heating film reaches a certain temperature, the electric heating device is turned off to stop heating. The other is to automatically shut down the electric heating device at a time, that is, the electric heating device automatically shuts down after heating for a certain time. Whether the electric heating device is turned off depends on the heating time and is not controlled by the heating temperature. Although the electric heating devices of the above two methods can heat the target areas that need to be heated in the vehicle, the heating device often disconnects prematurely or untimely during heating. Therefore, when the electric heating device is disconnected prematurely, the heating effect does not reach the ideal effect, or the electric heating device is not disconnected in time, resulting in a safety hazard caused by excessively high heating temperature.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0017] Among them, after the electric heating film is heated to the target temperature, the temperature control switch is disconnected and outputs a first feedback signal to the controller, and the temperature sensor outputs a second feedback signal to the controller. The controller is used to receive the first feedback signal and the second feedback signal, and turn off the electric heating film according to the first feedback signal and the second feedback signal.

[0041] The utility model provides an electric heating device for a vehicle, wherein the vehicle is provided with a controller 30 and a target area to be heated.

[0042] like Figure 1 - Figure 4As shown, the electric heating device may include a bracket 50, an electric heating film 10, a temperature control switch 20 or a temperature sensor 40, wherein the bracket 50 is arranged on a vehicle; the electric heating film 10 is used to heat the target area that needs to be heated, the electric heating film 10 is installed on the bracket 50, and is connected to the controller 30, and power can be supplied to the electric heating film 10 through the controller 30; the temperature control switch 20 is connected to the controller 30, and the temperature control switch 20 has a first temperature measuring end 201, and the first temperature measuring end 201 is connected to the electric heating film 10; the temperature sensor 40 is used to measure the heating temperature of the electric heating film 10, the temperature sensor 40 is connected to the controller 30, and the temperature sensor 40 has a second temperature measuring end 401, and the second temperature measuring end 401 is connected to the electric heating film 10.

[0043] Specifically, Figure 1 , Figure 2 As shown, only one temperature control switch 20 may be provided on the electric heating film 10, and the first temperature measuring end 201 of the temperature control switch 20 is connected to the electric heating film 10 to measure the heating temperature of the electric heating film 10. When the electric heating film 10 is heated to the target temperature, the temperature control switch 20 is disconnected and outputs a first feedback signal to the controller 30. The controller 30 is used to receive the first feedback signal and stop supplying power to the electric heating film 10 according to the first feedback signal, that is, disconnect the electric heating film 10 to stop heating the electric heating film 10.

[0044] Among them, when only one temperature control switch 20 is set on the electric heating film 10, a first time value can be set in the controller 30. When the disconnection time of the electric heating film 10 is the first time value, the controller 30 is also used to output a third control signal to the electric heating film 10 to start the electric heating film 10 for heating, that is, the electric heating film can be automatically started after being disconnected for the first time value.

[0045] Or, if Figure 3 , Figure 4 As shown, only one temperature sensor 40 may be provided on the electric heating film 10, and the second temperature measuring end 401 of the temperature sensor 40 is connected to the electric heating film 10 to measure the heating temperature of the electric heating film 10. When the electric heating film 10 is heated to the target temperature, the temperature sensor 40 outputs a second feedback signal to the controller 30. The controller 30 is used to receive the second feedback signal and stop supplying power to the electric heating film 10 according to the second feedback signal, that is, disconnect the electric heating film 10 to stop heating the electric heating film 10.

[0046] Among them, when the electric heating film 10 is only provided with one temperature sensor 40, a first start value can be set in the controller 30. When the temperature value measured by the temperature sensor 40 is the first start value, a fourth control signal is output to the controller 30. The controller 30 is used to receive the fourth control signal and start the electric heating film 10 for heating according to the fourth control signal.

[0047] In some embodiments, Figure 1 , Figure 3 As shown, the temperature control switch 20 or the temperature sensor 40 can be attached to the electric heating film 10 when provided. For example, the temperature control switch 20 or the temperature sensor 40 can be attached to the electric heating film 10 by gluing.

[0048] When the temperature control switch 20 or the temperature sensor 40 is connected to the controller 30 , a plurality of pins may be provided on the electric heating film 10 . For example, two groups of pins (each group of pins consists of two pins) may be provided on the electric heating film 10 .

[0049] When only one temperature control switch 20 is provided on the electric heating film 10, the two output ends of the temperature control switch 20 can be respectively connected to two pins in the same group of pins, and then the two pins are connected to the controller 30 to complete the connection between the temperature control switch 20 and the controller 30. Similarly, the two ends (positive pole and negative pole) of the electric heating film 10 can be respectively connected to two pins in another group of pins, and then the two pins are connected to the controller 30 through the lead 90 to complete the connection between the electric heating film 10 and the controller 30.

[0050] When only one temperature sensor 40 is provided on the electric heating film 10, the two output ends of the temperature sensor 40 can be respectively connected to two pins in the same group of pins, and then the two pins are connected to the controller 30 through the lead 90, so that the connection between the temperature sensor 40 and the controller 30 can be completed. The connection between the electric heating film 10 and the controller 30 can refer to the above-mentioned connection method and will not be repeated here.

[0051] In some embodiments, Figure 5 , Figure 6 As shown, a temperature control switch 20 is provided on the electric heating film 10, and a temperature sensor 40 is also provided. The first temperature measuring end 201 of the temperature control switch 20 and the second temperature measuring end 401 of the temperature sensor 40 are both connected to the electric heating film 10 to measure the heating temperature of the electric heating film 10. When the electric heating film 10 is heated to the target temperature, the temperature control switch 20 is disconnected and outputs a first feedback signal to the controller 30, and the temperature sensor 40 outputs a second feedback signal to the controller 30. The controller 30 is used to receive the first feedback signal and the second feedback signal, and shut down the electric heating film 10 according to the first feedback signal and the second feedback signal.

[0052] When the electric heating film 10 is provided with a temperature control switch 20 and a temperature sensor 40, a first time value or a first start value may be set in the controller 30; when the first time value is set, when the electric heating film is turned off for the first time value, the controller 30 outputs a third control signal to the electric heating film 10 to start the electric heating film 10 for heating;

[0053] When the first start value is set, when the temperature value measured by the temperature sensor 40 is the first start value, a fourth control signal is output to the controller 30, and the controller 30 is also used to receive the fourth control signal and start the electric heating film 10 for heating according to the fourth control signal.

[0054] In this embodiment, the controller 30 turns off the electric heating film according to the first feedback signal and the second feedback signal to avoid accidentally shutting down the electric heating film 10. For example, when only one temperature control switch 20 is provided on the electric heating film 10, if the temperature control switch 20 fails and is mistakenly disconnected, the controller 30 will turn off the electric heating film 10 before the target temperature is not heated. For another example, when only one temperature sensor 40 is provided on the electric heating film 10, if the temperature sensor 40 fails and causes the measured temperature value to be higher than the actual temperature, the controller 30 will turn off the electric heating film 10 before the target temperature is not heated.

[0055] In some embodiments, the temperature control switch 20 and the temperature sensor 40 can be attached to the electric heating film 10 when they are provided. For example, the temperature control switch 20 and the temperature sensor 40 can be attached to the electric heating film 10 by gluing.

[0056] Among them, when the temperature control switch 20 and the temperature sensor 40 are connected to the controller 30, a number of pins can be set on the electric heating film 10. For example, three groups of pins (each group of pins consists of two pins) can be set on the electric heating film 10, and the two output ends of the temperature control switch can be respectively connected to two pins in the same group of pins, and then the two pins are connected to the controller 30 through the lead 90, so that the connection between the temperature control switch 20 and the controller 30 can be completed, the two ends (positive and negative) of the electric heating film 10 can be respectively connected to two pins in another group of pins, and then the two pins are connected to the controller 30 through the lead 90, so that the connection between the electric heating film 10 and the controller 30 can be completed, the two output ends of the temperature sensor 40 can be respectively connected to two pins in the last group of pins, and then the two pins are connected to the controller 30 through the lead 90, so that the connection between the temperature sensor 40 and the controller 30 can be completed.

[0057] It can be seen that when the electric heating device heats the target area on the vehicle that needs to be heated, the working condition of the electric heating film 10 can be controlled according to the first feedback signal and / or the second feedback signal to realize the automatic shutdown of the electric heating film 10. Since the heating device is turned off when the target temperature is reached, the heating temperature will not be too high, thereby ensuring the safety of the heating process. At the same time, the electric heating film will not be disconnected in advance, thereby ensuring the heating effect.

[0058] In addition, the arrangement of pins on the electric heating film 10 facilitates the connection between the electric heating film 10 and the controller 30 , and also facilitates the connection between the temperature control switch 20 and / or the temperature sensor 40 and the controller 30 .

[0059] In this embodiment, when setting the target temperature, those skilled in the art can set it by themselves according to the actual application situation. For example, it can be set according to parameters such as the minimum temperature and the maximum temperature of the area where the electric heating device for a vehicle is used; for another example, it can be set according to the specific location of the target area that needs to be heated on the vehicle. Without going into details here, the target temperature can be set by oneself, which increases the scope of application of the electric heating device for a vehicle.

[0060] Similarly, when setting the first time value or the first start value, those skilled in the art may also set them according to actual application conditions, and no further details will be given here.

[0061] In some embodiments, Figure 7 , Figure 8 and Fig. 9 As shown, the electric heating film 10 may include a first area 101 and a second area 102; wherein the first area 101 is adjacent to the target area to be heated; and there is a first distance 103 between the second area 102 and the target area to be heated.

[0062] Specifically, when the first area 101 is set, it can be directly attached to the target area to be heated; wherein, when heating the target area to be heated, since the first area 101 on the electric heating film 10 is attached to the target area to be heated, the first area 101 on the electric heating film 10 heats the target area to be heated by transferring heat; since there is a first distance 103 between the second area 102 and the target area to be heated, the second area 102 on the electric heating film 10 heats the target area to be heated by radiant heat transfer, so that the electric heating device heats the target area to be heated by combining radiant heat transfer and heat transfer, so as to achieve multi-dimensional heating.

[0063] Here, it should be noted that the specific setting positions of the first area 101 and the second area 102 can be adjusted by those skilled in the art according to actual conditions, that is, those skilled in the art can determine the portion of the electric heating film 10 that contacts the target area to be heated (capable of heating the target area to be heated by transferring heat) and the portion of the electric heating film 10 that does not contact the target area to be heated (capable of heating the target area to be heated by radiant heat transfer) according to actual conditions. Therefore, the specific setting positions of the first area 101 and the second area 102 are not overly limited here.

[0064] In some embodiments, the vehicle may include a vehicle. Figure 1 , Figure 3 , Figure 5 as well as Figure 7 - Fig. 9 As shown, the target area that needs to be heated may include the front windshield 80 of the vehicle; of course, the target area that needs to be heated may also include other locations, such as the rear windshield, sunroof, A-pillar, B-pillar and other areas in the vehicle that need to be heated.

[0065] In this embodiment, if Figure 1 , Figure 3 and Figure 5 As shown, an image capture sensor 60 may be disposed on the bracket 50, and the image capture sensor 60 may capture image data through the front windshield 80 of the vehicle, wherein the output end of the image capture sensor 60 may be connected through a lead 90. Specifically, the image capture sensor 60 may be a sensor capable of capturing image data, such as a camera or a laser.

[0066] Furthermore, the means of transportation may also be other means, such as airplanes, ships, other locomotives, etc.

[0067] In some embodiments, controller 30 may be an onboard controller.

[0068] Among them, when only the temperature control switch 20 is provided on the electric heating film 10, the temperature control switch 20 can be connected to the vehicle-mounted controller, and the electric heating film 10 is powered by the vehicle-mounted controller. After the electric heating film 10 is heated to the target temperature, the temperature control switch 20 is disconnected and outputs a first feedback signal to the vehicle-mounted controller. The vehicle-mounted controller receives the first feedback signal and turns off the electric heating film 10 according to the first feedback signal, that is, stops supplying power to the electric heating film 10; when only the temperature sensor 40 is provided on the electric heating film 10, the temperature sensor 40 can be connected to the vehicle-mounted controller. Similarly, the electric heating film 10 is powered by the vehicle-mounted controller. After the electric heating film 10 is heated to the target temperature, the temperature sensor 40 outputs a second feedback signal to the vehicle-mounted controller. The on-board controller receives the second feedback signal and turns off the electric heating film 10 according to the second feedback signal, that is, stops supplying power to the electric heating film 10; when the temperature control switch 20 is provided on the electric heating film 10 and the temperature sensor 40 is also provided, the temperature control switch 20 and the temperature sensor 40 can be connected to the on-board controller. Similarly, the electric heating film 10 is powered by the on-board controller. After the electric heating film 10 is heated to the target temperature, the temperature control switch 20 outputs the first feedback signal, and the temperature sensor 40 outputs the second feedback signal. The on-board controller receives the first feedback signal and the second feedback signal, and turns off the electric heating film 10 according to the first feedback signal and the second feedback signal, that is, stops supplying power to the electric heating film 10.

[0069] Furthermore, the electric heating device also includes a shell 70 having a accommodating chamber 701, and the bracket 50, the electric heating film 10, the temperature control switch 20 and / or the temperature sensor 40 and the image capture sensor 60 are arranged in the accommodating chamber 701 of the shell 70 to further protect the bracket 50, the electric heating film 10, the temperature control switch 20 and / or the temperature sensor 40 and the image capture sensor 60, etc., and extend the service life of the bracket 50, the electric heating film 10, the temperature control switch 20 and / or the temperature sensor 40 and the image capture sensor 60, etc.

[0070] When the electric heating device for a vehicle is specifically set up, the temperature control switch 20 and / or the temperature sensor 40 (only the temperature control switch 20 is set on the electric heating film 10, or, only the temperature sensor 40 is set on the electric heating film 10, or the temperature control switch 20 and the temperature sensor 40 are simultaneously set on the electric heating film 10) can be first set on the electric heating film 10, and then the electric heating film 10 is installed on the bracket 50, and the image capture sensor 60 can be further installed on the bracket 50, and the bracket 50 is installed in the accommodating chamber 701 of the shell 70, and finally the shell 70 is installed on the vehicle, and the electric heating film 10, the temperature control switch 20 and / or the temperature sensor 40 (only the temperature control switch 20 is set on the electric heating film 10, or, only the temperature sensor 40 is set on the electric heating film 10, or the temperature control switch 20 and the temperature sensor 40 are simultaneously set on the electric heating film 10) are connected to the controller 30, so that the target area to be heated can be heated after the electric heating film 10 is powered on.

[0071] Here, it should be noted that when the electric heating device is installed on a vehicle, the specific location of the target area to be heated needs to be considered, that is, the installed electric heating film 10 can heat the target area to be heated.

[0072] In summary, the electric heating device for a vehicle provided by the utility model has the following beneficial effects:

[0073] The heating temperature of the electric heating film 10 is measured by the temperature control switch 20 or the temperature sensor 40. When heated to the target temperature, the temperature control switch 20 is disconnected and outputs a first feedback signal to the controller 30, or the temperature sensor 40 outputs a second feedback signal to the controller 30. The controller 30 receives the first feedback signal or the second feedback signal, and turns off the electric heating film 10 according to the first feedback signal or the second feedback signal. It can be seen that when the electric heating device heats the target area to be heated, it can turn off the electric heating film 10 according to the first feedback signal or the second feedback signal to realize automatic shutdown of the electric heating film 10. Since the heating device is turned off when the target temperature is reached, the heating temperature will not be too high, thereby ensuring the safety of the heating process. At the same time, the electric heating film will not be disconnected prematurely, thereby ensuring the heating effect.

[0074] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
