[0008] As an improvement, the width of the first annular groove is the same as that of the second annular groove.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] Glue bonding and ultrasonic welding are arranged at the joint surface of the mask and the base, and the glue bonding and ultrasonic welding complement each other, so that the joint between the mask and the base is more secure and the sealing performance of the joint between the two is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a cross-sectional view of the utility model.

[0012] Figure 2 for Figure 1 Enlarged view of point A. DETAILED DESCRIPTION

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] like Figure 1 , 2As shown, a suspended car logo includes a base 3, a mask 1 sealed with the base 3, a car logo cover 2 pivotally connected with the base 3, and a counterweight arranged on the car logo cover 2. The mask 1 and the base 3 form a closed space, and the car logo cover 2 is arranged in the closed space. The mask 1 includes a transparent cover and a first annular boss 4 arranged on the edge of the transparent cover and molded by two-color injection molding.
