[0028] The utility model relates to a kind of back door resonator of car of convenient installation, asFigures 1-2 As shown in the drawings, it comprises a base 1 for mounting with the back door of a car, a movable assembly 2 mounted on the base 1 and a resonant block body 3 mounted on the base 1 through the movable assembly 2.

[0029] The base 1 has a square base 11, and recessed portions 14 are formed at the four corners of the top surface of the base 11 and recessed towards the bottom surface. Second through holes 15 are formed in the recessed portions 14 along the recessed direction, for inserting fasteners such as bolts, so as to mount and fix the base 1 with the back door of a car. Figures 2-3 As shown in the drawings, a groove portion 12 is formed in the top surface of the square base 11 and recessed towards the bottom surface. The groove portion 12 has a strip structure with a "T" shaped cross section, and the movable assembly 2 is arranged in the groove portion 12. At one end of the base 11, a first through hole 13 is formed along the extension direction of the groove portion 12 and communicates with the groove portion 12.

[0030] As shown in the drawings, the movable assembly 2 comprises movable members 21 arranged oppositely and one end of each movable member 21 is slidingly connected in the groove portion 12, and a bidirectional screw 22 is rotatably connected in the groove portion 12 and connected with the movable members 21. Figure 2 As shown in the drawings, the movable member 21 has a "T" shaped movable portion two 212 matched with the groove portion 12, and a movable portion one 211 is integrally connected with the top of the movable portion two 212. Third and fourth through holes 213 and 214 are formed in the surfaces of the movable portion one 211 and the movable portion two 212 along the length direction of the groove portion 12, respectively. Figure 4 Specifically, one end of the bidirectional screw 22 is inserted into the groove portion 12 from the first through hole 13, and then penetrates the fourth through holes 214 of the two movable members 21 in sequence, and a rotary support 24 connected with the end of the bidirectional screw 22 forms rotation on the inner wall of the groove portion 12 opposite to the first through hole 13. The other end of the bidirectional screw 22 away from the rotary support 24 extends outside the first through hole 13 and is connected with a rotating portion 23. When the rotating portion 23 is rotated, the bidirectional screw 22 can be rotated in the groove portion 12. In the embodiment, the rotary support 24 is preferably a bearing. The inner wall of the fourth through hole 214 is provided with a threaded rib, and the bidirectional screw 22 is threadedly connected with the fourth through hole 214 and the movable member 21 to form a threaded connection. When the bidirectional screw 22 is rotated, the two movable members 21 can slide towards or away from each other along the groove portion 12 under the action of the thread, so as to adjust the distance between the two movable members 21.

[0031] As shown in the drawings, the resonant block body 3 comprises a mass block 31 and a cladding layer 32 wrapping the mass block 31. The mass block 31 has columnar insertion portions 4 extending axially at both ends and matched with the third through holes 213. The insertion portions 4 can be inserted into the third through holes 213, so as to be arranged between the two movable members 21 and mounted and fixed with the base 1.

[0032] Figures 1-3 As shown in the drawings, the resonant block body 3 comprises a mass block 31 and a cladding layer 32 wrapping the mass block 31.
