[0018] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] See also Figure 1 、 Figure 2 and Figure 3A silent lock structure includes a lock plate 1, a groove 101 is provided at the lower end of the lock plate 1, a U-shaped lock pin 2 is fixed to the upper end of the lock plate 1, the lower end of the lock pin 2 is located in the groove 101, and the lower end surface of the lock pin 2 is located in the same horizontal plane as the lower end surface of the lock plate 1. The groove 101 is provided at the lower end of the lock plate 1, and the fixed connection between the lock pin 2 and the lock plate 1 is set in the groove 101, so that the lower end surface of the lock pin 2 and the lower end surface of the lock plate 1 are in the same horizontal plane, preventing the lock pin 2 from directly hitting the car body when locking the car door. At this time, the force generated by the car door collision will be transmitted to the silencer block 3 and the upper gasket through the lock plate 1. 4 and the lower gasket 5 are used for shock absorption to reduce the generation of noise. The upper end of the lock plate 1 is provided with two bilaterally symmetrical through holes 102. The left and right ends of the lock plate 1 are provided with silencer blocks 3. The silencer blocks 3 are composed of a semicircle and a rectangle. The lower end of the semicircle of the silencer block 3 is provided with an arc-shaped buffer zone. When the car door hits the lock pin 2, the force will act on the silencer block 3, causing the silencer block 3 to deform. Then, the silencer block 3 will deform and change toward the buffer zone of the silencer block 3, so that the silencer block 3 will be consistent with the normal projection size of the silencer block 3 after deformation, thereby preventing the silencer block 3 from squeezing other parts of the vehicle after deformation.

[0020] See also Figure 2 、 Figure 3 and Figure 4, the upper ends of the two muffler blocks 3 are respectively provided with fixing holes 302, and the opposite sides of the two fixing holes 302 are respectively provided with arched plugging grooves 301, and the left and right ends of the lock plate 1 are plugged into the plugging grooves 301 of the muffler block 3, and the fixing holes 302 are coaxially arranged with the through hole 102 of the lock plate 1, and the upper ends of the fixing holes 302 are chamfered. The chamfered upper ends of the fixing holes 302 are convenient for quickly installing the upper gasket 4 in the fixing holes 302, and at the same time, the fixing holes 302 are coaxially arranged with the through hole 102, which is convenient for quickly passing the bolts when fixing the device. The device is fixed through the fixing hole 302 and the through hole 102. The lower end of the fixing hole 302 is provided with a sink. The upper end of the muffler block 3 is provided with an upper gasket 4, and the lower end of the muffler block 3 is provided with a lower gasket 5. The upper gasket 4 and the lower gasket 5 are detachably connected. By providing muffler blocks 3 at the left and right ends of the lock plate 1, and setting upper gaskets 4 and lower gaskets 5 in the fixing holes 302 of the muffler block 3, after the device is fixed to the vehicle body by bolts, the vehicle door is closed, and when the vehicle lock and the lock pin 2 are engaged and collided, the upper gasket 4 and the lower gasket 5 are used for the first shock absorption, and after the shock absorption, the muffler block is used. 3 performs a second shock absorption to prevent the lock plate 1 from directly contacting the vehicle body and reduce noise generation. An annular snap ring 401 is fixed to the lower end of the upper gasket 4, and an annular snap groove 502 is provided at the upper end of the lower gasket 5. The snap ring 401 is inserted into the snap groove 502. By providing the snap ring 401 at the lower end of the upper gasket 4 and providing the snap groove 502 at the upper end of the lower gasket 5, a detachable connection between the upper gasket 4 and the lower gasket 5 is achieved. When fixing the device, the bolt will directly contact the upper gasket 4 and the lower gasket 5. When the door is repeatedly opened and closed, the bolt will contact the upper gasket 4. The upper gasket 4 and the lower gasket 5 cause slight friction, resulting in wear of the upper gasket 4 and the lower gasket 5. The upper gasket 4 and the lower gasket 5 are detachably connected by the snap ring 401 and the snap groove 502, which is convenient for replacing the upper gasket 4 and the lower gasket 5. The lower end of the lower gasket 5 is provided with multiple countersunk holes 501 along its circumference. The countersunk holes 501 are provided at the lower end of the lower gasket 5. The countersunk holes 501 can be used as suction cups to be adsorbed on the vehicle body, which facilitates preliminary fixation when installing the device. At the same time, when the lock plate 1 squeezes the lower gasket 5, the lower gasket 5 is firmly adsorbed on the vehicle body, ensuring the fixation of the lower gasket 5 and the upper gasket 4.

[0021] When the utility model is installed and used:

[0022] During installation, fix the lock plate 1 and the lock pin 2, fix the lower gasket 5 to the vehicle body by adsorbing it through the countersunk hole 501, insert the muffler block 3 into both ends of the lock plate 1 through the insertion groove 301, insert the fixing hole 302 of the muffler block 3 into the lower gasket 5, use the upper gasket 4 to connect the upper gasket 4 and the lower gasket 5 through the fixing hole 302, and use bolts to pass through the upper gasket 4 and the lower gasket 5 to fix the device to the vehicle body.

[0023] During use, when the door collision lock pin 2 is completed and fixed, when the door hits the lock pin 2, the force generated by the door impact will be transmitted to the silencer block 3, the upper gasket 4 and the lower gasket 5 through the lock plate 1 for shock absorption, thereby reducing the generation of noise. At the same time, the force acts on the silencer block 3, causing the silencer block 3 to deform, and then the silencer block 3 will deform and change toward the buffer zone of the silencer block 3, so that the silencer block 3 will be consistent with the normal projection size of the silencer block 3 after deformation, thereby preventing the silencer block 3 from squeezing other parts of the vehicle after deformation.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
