Description

Technical Field

[0001] The utility model relates to the technical field of automobile cables, in particular to an anti-frost device for automobile hand brake cables. Background Art

[0002] The automobile handbrake cable anti-frost device is a device used to prevent the handbrake cable from freezing in low temperature environments. The purpose of this device is to ensure that the handbrake system can still work reliably in winter or humid environments to prevent brake failure caused by cable freezing.

[0003] In view of the existing related technologies, the inventors believe that the following defects often exist: the device is a device that prevents the handbrake lock from freezing and icing under extremely cold conditions. According to research, many northern car owners pull the handbrake after parking their private cars, and the next day they often find that the handbrake cable is frozen and frozen, making it impossible to release the handbrake. There are even cases where the handbrake cable is directly broken due to forced release of the handbrake after excessive frost. The device can detect the temperature of the handbrake cable (other cables, pull wires) in real time. When the temperature is lower than the specified value, the heater is controlled to heat and melt the frost on the cable to prevent the cable from freezing and icing. Utility Model Content

[0004] The technical problem to be solved by the utility model is that: in the prior art, the hand brake cable is frozen and iced, resulting in the disadvantage that the hand brake cannot be released. For this reason, we propose an anti-frost device for the automobile hand brake cable.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions: A car handbrake cable anti-frost device, comprising a heating plate, one end of the heating plate is electrically connected to a heating drive module, the bottom end of the heating drive module is electrically connected to an Arduino microcontroller, an external expansion board is installed on the surface of the Arduino microcontroller, a temperature sensor is installed on the surface of the Arduino microcontroller, a 9V DC power supply is installed inside the Arduino microcontroller, and the surface of the heating plate is electrically connected to a cable body.

[0006] Preferably, the positive and negative electrodes of the heating plate are electrically connected to the surface of the heating driving module.

[0007] Preferably, the heating drive module is electrically connected to the external expansion board.

[0008] Preferably, the heating driving module is electrically connected to the temperature sensor, and the temperature sensor is electrically connected to the external expansion board.

[0009] Preferably, the Arduino single chip microcomputer is in the shape of a rectangle.

[0010] Preferably, the 9V DC power supply is cylindrical in shape.

[0011] Technical effects and advantages of the utility model:

[0012] In the utility model, the structure of the device is composed of a heating plate, a heating drive module, an Arduino single-chip computer, an external expansion board, a temperature sensor, and a 9V DC power supply. The principle of the device is to use a temperature sensor to detect the real-time temperature of the cable. When the cable temperature is lower than 0 degrees Celsius, the Arduino single-chip computer controls the heating drive module to work, so that the heating plate heats the cable, thereby removing the frost on the cable, and achieving the function of preventing the cable from frost and ice; when the temperature is higher than 30 degrees Celsius, the Arduino single-chip computer controls the heating drive module to stop working and cut off the heating of the heating plate. The purpose of such control is to prevent unnecessary burns caused by excessively high temperature of the heating plate, and on the other hand, it can also reduce the energy consumption of the system, because the heating plate requires a large current and consumes a lot of power.

[0023] Working principle: The principle of this device is to use the temperature sensor 5 to detect the real-time temperature of the cable. When the cable temperature is lower than 0 degrees Celsius, the Arduino microcontroller 3 controls the heating drive module 2 to work, so that the heating plate 1 heats the cable, thereby removing the frost on the cable and preventing the cable from freezing. When the temperature is higher than 30 degrees Celsius, the Arduino microcontroller 3 controls the heating drive module 2 to stop working and cut off the heating of the heating plate 1. The purpose of such control is to prevent unnecessary burns caused by the excessive temperature of the heating plate 1 on the one hand, and on the other hand, it can also reduce the energy consumption of the system, because the heating plate 1 requires a large current and consumes a lot of power.
