Preferably, a stopper 9 is further installed on the upper portion of the guide bar 10.
Preferably, the cam 3 is in the same plane as the slide 13.
Optionally, the frame 6 is of a U-shaped structure, and the magnet 7 is of a U-shaped structure.
Optionally, the magnet 7 is a hoof-shaped magnet, the heating block 20 is a hollow structure and made of a copper material, and a resistance wire is wound inside the heating block 20.

In this embodiment, the displacement device mainly comprises a vertical displacement assembly and a horizontal displacement assembly. The length of the coil 8 determines, among other things, the sensitivity of the temperature-controlled adjustment. Typically, the only part of the length of the coil that is within the magnet is the effective length to cut the magnetic field lines to generate electrical energy. Considering the misalignment, such as 2 width of the magnet and 3 length of the coil, this 2 length part of the coil is effective to cut the magnetic induction line, but the part without the coil slides into the magnet by the misalignment of the coil and the magnet, the magnetic induction line is not cut, and the electric energy generated by the coil on the periphery to the magnetic induction cutting is usually negligible. If the length of the coil is 5 or 6, the slide bar needs to slide for a longer distance to not cut the magnetic induction line, so that the sensitivity of the battery temperature control adjustment is related to the length of the coil. For example, the length of the coil is only 2, and the coil and the magnet are the same as the width of the magnet, so that the coil and the magnet are dislocated when the vehicle runs slightly, and if the length of the coil is long, the coil and the magnet are dislocated when the vehicle is repeatedly started and stopped, ascends and descends, turns or runs quickly, so that the sensitivity is set in summer, and the sensitivity is reduced in winter, namely the length of the coil is lengthened in consideration of the use environment of the vehicle.

Therefore, in the present embodiment, even in the running state of the automobile, the direct shutdown processing of the motor is abandoned. Meanwhile, the mode that this application supplies power to the heating block with the mode of cutting the magnetic induction line is exactly to heating block automatic adjustment control, can follow the theory of operation and see out, and the cutting magnetic induction line is not for energy-conservation, but realizes the automatic control to the heating block according to the state of traveling of car, compares in directly supplying power to the heating block, can better realize adjusting the heating effect of heating block according to the state of traveling.
