The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

A sealing structure for detecting the air tightness of a car lamp is shown in figure 1, and comprises a bottom plate 1, a bearing sealing table 2, a cover pressing piece 3 and a lifting mechanism 4; the bearing sealing table 2 and the lifting mechanism 4 are arranged on the bottom plate 1; the cover pressing piece 3 is correspondingly arranged with the bearing sealing table 2 to construct and form a jogged sealing cavity; the lifting mechanism 4 is connected with the cover pressing member 3, and the lifting mechanism 4 is used for controlling the movement of the cover pressing member 3 in the vertical direction.

In particular, the base plate 1 provides a stable physical space for other components; the bearing sealing table 2 is used for placing and sealing the lamp; the cover pressing piece 3 can be correspondingly embedded with the bearing sealing table 2 to form a closed space suitable for the lamp; the lifting mechanism 4 can control the movement of the cover pressing piece 3, so that the cover pressing piece 3 can press down the bearing sealing table 2 to cover or lift away to open the lamp inlet and outlet on the bearing sealing table 2.

Further, a screw hole 11 is arranged on the bottom plate 1; the bearing sealing table 2 and the lifting mechanism 4 are connected with the bottom plate through screw holes 11 by bolts.

Specifically, because the carrier lamps are various, the bearing sealing table 2 is also of various types, and therefore the screw hole positions on the bottom plate 1 can be variously set according to the bearing sealing table 2 of various types, and the sealing structure can be suitable for lamps of various types; likewise, a suitable lifting mechanism 4 can be flexibly arranged on the bottom plate 1 according to the requirements of various lamps.

Further, the load bearing seal stage 2 includes: a base 21, a boss 22 and an inner cavity 23; the base table 21 is arranged on the bottom plate 1, and the boss 22 is arranged on the base table 21; the inner cavity 23 is arranged on the base table 21 and the boss 22, and the inner cavity 23 is used for placing a car lamp; the cover member 3 is fitted and sealed with the boss 22.

Further, the bearing sealing table 2 further comprises a sealing ring 24; the seal 24 is disposed on the boss 22 and is disposed coaxially with the cavity 23.

Specifically, the sealing ring 24 may be circular, and made of rubber or silica gel, and is adhered to the boss 22 by soft adhesive, and when the bearing sealing platform 2 seals with the cover pressing member 3, the sealing ring 24 contacts with the cover pressing member 3, so as to play a role in isolating air from the first layer. The friction that the bearing seal platform 2 directly contacts with the cover pressing piece 3 is reduced, the problem that the lower surface of the cover pressing piece 3 is uneven because the processing and assembling precision is not in place and a seal cavity cannot be formed by the bearing seal platform 2 is avoided, and the false detection problem is caused by unsealing in the detection process.

Further, the seal 24 is semi-buried on the boss 22.

Specifically, the sealing ring 24 is half-buried on the boss 22, at this time, the sealing ring 24 is more stable on the boss 22, and when the bearing sealing platform 2 is sealed with the cover pressing piece 3, the sealing ring 24 is in contact with the cover pressing piece 3, and the effect of isolating air is better.

Further, the bearing sealing table 2 further comprises a vent hole 25; the vent 25 is provided in the base 21.

Specifically, the material of the flexible pad 33 may be silica gel or rubber, and the thickness may be 2-3mm, and the flexible pad 33 is disposed on the side of the cover 31 facing the boss 22. Therefore, when the cover 31 is sealed with the bearing sealing table 2, the flexible pad 33 on the bottom of the concave groove 32 on the inner side of the cover 31 is in soft contact sealing with the table top of the boss 22 on the bearing sealing table 2 and the semi-buried sealing ring 24 on the table top, meanwhile, the flexible pad 33 on the wall of the concave groove 32 on the inner side of the cover 31 is in soft contact sealing with the side surface of the boss 22 on the bearing sealing table 2, and the flexible pad 33 on the outer side of the concave groove 32 on the inner side of the cover 31 is in soft contact sealing with the periphery of the upper side of the bottom table 21 on the bearing sealing table 2, so that a second layer of air isolation is formed, and the sealing effect is excellent.

Further, the lifting mechanism 4 includes a mounting frame 41, a linear guide 42, and a driving member 43; the mounting frame 41 is arranged on the bottom plate 1, the linear guide rail 42 is arranged on the mounting frame 41 along the vertical direction, and the cover pressing piece 3 is connected with the linear guide rail 42; the driving member 43 is connected with the linear guide rail 42, and the linear guide rail 42 can move in the vertical direction under the action of the driving member 43, so as to drive the cover member 3 to ascend or descend.
