DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-4 , an embodiment provided by the utility model:

[0022] A car tailgate lock, comprising:

[0023] The device body includes a tailgate lock body 100:

[0024] A protective box body 110 is arranged on the outside of the tailgate lock body 100, a connecting shaft 113 is arranged on one side of the protective box body 110, a protective plate 114 is arranged on the bottom of the connecting shaft 113, and the material of the protective plate 114 is made of transparent acrylic. A heating plate 111 is fixedly connected to the inside of the protective box body 110, and the number of the heating plates 111 is two. The outer surface of the heating plate 111 is fixedly connected to a heating tube 112 in a zigzag distribution. Slide grooves 115 are opened on both sides of the inside of the tailgate lock body 100, and a slider 116 is slidably installed inside the slide groove 115. A return spring 116 is fixedly installed on one side of the inner wall of the slide groove 115. 17. A damper is arranged inside the return spring 117, and the other side of the return spring 117 is fixedly connected to the outer side of the slider 116. A U-shaped clamping block 118 is fixedly installed on one side of the slider 116 close to each other. The setting of the protection box body 110, the connecting shaft 113 and the protection plate 114 can protect the tailgate lock body 100 on rainy days without affecting normal use. If rain and moisture enter the protection box body 110, turn on the switch to allow the heating plate 111 and the heating tube 112 to generate heat to dry the inside of the protection box body 110 to avoid rusting of the tailgate lock body 100 due to the inability to volatilize.

[0025] Furthermore, an anti-skid pad 119 is fixedly installed on one side of the U-shaped clamping blocks 118 that are close to each other.

[0026] Furthermore, a sealing rubber ring is provided on one side of the protective plate 114 close to the protective box body 110, and the sealing rubber ring is made of rubber. A groove matching the sealing strip is provided on the outer side of the protective box body 110. In actual use, through the setting of the above-mentioned structure, dust in the air can be prevented from entering the interior of the protective box body 110 under long-term use, thereby preventing damage to the tailgate lock body 100.

[0027] Furthermore, a drying chamber 120 is provided inside the protective box body 110, and a desiccant is placed inside the drying chamber 120. In actual use, through the setting of the above structure, the drying chamber 120 and the desiccant can prevent the interior of the protective box body 110 from being at high humidity for a long time, thereby preventing the tailgate lock body 100 from being damaged.

[0028] Furthermore, a plurality of air holes 121 are evenly arranged on the outer surface of the drying chamber 120, and a replacement door 122 is provided on one side of the drying chamber 120. In actual use, through the arrangement of the above structure, the air holes 121 not only increase the volatilization speed of the desiccant, but the replacement door 122 can also regularly replace the desiccant inside the drying chamber.

[0029] Furthermore, a sensing switch is provided on one side of the protective plate 114, and an infrared sensing switch is provided on the sensing switch. In actual use, through the setting of the above structure, the user can approach the infrared sensing switch with any part of the body, and then in order to avoid the possibility of accidental touch, the infrared sensing switch is set to sense the signal within a certain time.

[0030] Working principle: When in use, the protection box body 110, the connecting shaft 113 and the protection plate 114 can protect the tailgate lock body 100 on rainy days without affecting normal use. If rain and moisture enter the protection box body 110, turn on the switch to allow the heating plate 111 and the heating tube 112 to generate heat to dry the inside of the protection box body 110 to prevent the tailgate lock body 100 from rusting due to the inability to volatilize. The drying chamber 120 and the desiccant can prevent the interior of the protection box body 110 from being too humid for a long time and damaging the tailgate lock body 100. The air vent 121 not only increases the volatilization speed of the desiccant, but also the replacement of the hatch 122 can also regularly replace the desiccant inside the drying chamber.
