[0002] Car drawer refrigerators and drawer cup holders are commonly used in-vehicle electrical appliances in daily life. Their cooling and heating functions are mainly achieved by semiconductor refrigeration technology or compressor refrigeration technology. Existing products can provide a constant temperature storage environment, and the drawers can be opened and closed to meet basic functions. However, there are some obvious problems with the current products: 1. The current products require a relatively large internal space to meet the sufficient opening distance of the drawers, but in fact the surrounding environment of the device is restricted and cannot provide enough space; 2.

The sliding guide assembly is used to guide the device movable module 2 when it slides relative to the device fixed module 1, and the electric pulling drive assembly is used to drive the device movable module 2 to slide relative to the device fixed module 1.

[0028] Furthermore, the sliding guide assembly here includes a bottom plate 32 arranged on the inner side of the device fixed module 1, and a plurality of slide rails 33 are arranged between the device movable module 2 and the bottom plate 32.

In addition, a magnetic attraction structure is provided between the sealing shell 41 and the movable bracket 43, which can overcome the force of the spring 46 and make the movable bracket 43 move toward the sealing end of the sealing shell 41, so that the upper wear-resistant elastomer 44 and the lower wear-resistant elastomer 45 are separated from each other.

When the entire device active module 2 is in the closed state, the sealing device 4 is in a power-off condition, and two springs 46 act on the active bracket 43 to make the steel block 49 and the electromagnet 47 have a certain distance H. The two upper wear-resistant elastic bodies 44 and the two lower wear-resistant elastic bodies 45 act synchronously to clamp the pulling rope body 31. Since the pulling rope body 31 cannot move, the sealing function of the device active module 2 is completed.
