Of course, there are various connection methods between the spring and the fixed wheel assembly 10 and the movable wheel assembly 20, for example, the first bending section 311 and the second bending section 321 are respectively welded on the fixed wheel assembly 10 and the movable wheel assembly 20, or the first bending section 311 and the second bending section 321 are respectively clamped on the fixed wheel assembly 10 and the movable wheel assembly 20, and the like, and the connection method is not limited in detail herein.
Further, referring to fig. 1 to 4, a first insertion hole 122 is disposed on a side wall of the first cavity 121, and the first bending section 311 is inserted from the first insertion hole 122 and hooked in the first cavity 121. A second insertion hole 222 is formed in a sidewall of the second cavity 221, and the second bending portion 321 is inserted into the second insertion hole 222 and hooked in the second cavity 221. Because the fixed wheel assembly 10 and the movable wheel assembly 20 are respectively inserted at two ends of the spring, the first insertion hole 122 and the second insertion hole 222 are respectively formed in the side wall of the first cavity 121 and the side wall of the second cavity 221, so that the first bending section 311 can be conveniently inserted into the first cavity 121, and the second bending section 321 can be conveniently inserted into the second cavity 221.

The second bending section 321 includes a second bending section 3211 and a second straight section 3212 connected to each other, the second bending section 3211 is riveted to the moving wheel assembly 20, and the second straight section 3212 is inserted into the second cavity 221. Through increasing first straight section 3112, second straight section 3212 inserts first cavity 121, the degree of depth of second cavity 221, in order to guarantee that the deflection degree of first kink 311 and second kink 321 is greater than elastic element 30's resilience value, make first kink 311 hook locate in first cavity 121, second kink 321 hook establish with second cavity 221 in, thereby improve elastic element 30 and fixed wheel subassembly 10, the fastness of being connected between the driving wheel subassembly 20, ensure the tensile shrink function of carriage lid, improve the operational reliability of carriage lid.

In the present embodiment, the first bending section 311 is inserted into the first cavity 121 for a length of 13mm, and the second bending section 321 is inserted into the second cavity 221 for a length of 13 mm. The conventional rebounding device includes a rotating shaft, which is sequentially inserted into the first cavity 121, the spring, and the second cavity 221. Since the rotation shafts are disposed in the first and second cavities 121 and 221, the deformation degree of the springs inserted into the first and second cavities 121 and 221 is only 3 mm. After long-term stretching and shrinking, the riveted part of the spring is easy to rebound and recover, so that the spring is loosened from the fixed wheel assembly 10 and the movable wheel assembly 20, the stretching and shrinking functions of the carriage cover are disabled, and the working reliability of the carriage cover is reduced. In this embodiment, the rotating shaft is not arranged in the first cavity 121 and the second cavity 221, so that the deformation degree of the first bending section 311 and the second bending section 321 can be increased, the deformation degree of the first bending section 311 and the second bending section 321 is greater than the resilience value of the spring, the first bending section 311 is hooked in the first cavity 121, and the second bending section 321 is hooked in the second cavity 221, so that the connection strength of the spring, the fixed wheel assembly 10 and the movable wheel assembly 20 can be improved, the stretching and shrinking function of the carriage cover is ensured, and the working reliability of the carriage cover is improved.
In one embodiment, referring to fig. 2, the springs include a first spring 31, a second spring 32 and a third spring 33 connected to each other, the third spring 33 is disposed between the first spring 31 and the second spring 32, and the pitch of the first spring 31 and the second spring 32 is smaller than the pitch of the third spring 33. When the carriage cover is in a closed state, the first spring 31, the second spring 32 and the third spring 33 are twisted, the thread pitch of the first spring 31, the second spring 32 and the third spring 33 is gradually reduced, and elastic potential energy convenient for opening and recovering the carriage cover is generated. In addition, because the screw pitches of the first spring 31 and the second spring 32 are smaller than the screw pitch of the third spring 33, when the car body cover is in a closed state, compared with the third spring 33, the torsional amplitudes of the first spring 31 and the second spring 32 are smaller, so that the phenomenon that the stretching and contracting functions of the car body cover are disabled due to the fact that the first bending section 311 and the fixed wheel assembly 10 are loosened and the second bending section 321 and the driving wheel assembly 20 are loosened can be avoided.
Specifically, in order to connect the first spring 31, the second spring 32, and the third spring 33 together, the third spring 33 is fixed between the first spring 31 and the second spring 32 by welding.
Further, the inner diameters of the first spring 31 and the second spring 32 are smaller than the inner diameter of the third spring 33. When the springs are twisted, the load of the first spring 31 and the second spring 32 which increase the twisting angle of 1 degree is larger than the load of the third spring 33 which increase the twisting angle of 1 degree, so that the phenomenon that the stretching and contracting functions of the carriage cover are invalid due to the fact that the first bending section 311 and the fixed wheel assembly 10 are loosened and the second bending section 321 and the movable wheel assembly 20 are loosened can be avoided.
In one embodiment, referring to fig. 1 and 2, the rebounding device further includes a sleeve 40, and the sleeve 40 is sleeved on the spring.

The fixed wheel 11 is connected with the first bending section 311 through a first metal connecting cylinder, the driving wheel 21 is connected with the second bending section 321 through a second metal connecting cylinder, the first metal connecting cylinder and the second metal connecting cylinder can be guaranteed to be connected with the first bending section 311 under the action of elastic potential energy, the connection position of the second bending section 321 is not deformed and damaged, the first bending section 311 is effectively improved, the second bending section 321 is respectively connected with the fixed wheel assembly 10 and the driving wheel assembly 20, the connection strength between the first bending section 311 and the first metal connecting cylinder is prevented, the second bending section 321 is prevented from being separated from the driving wheel assembly 20, and the phenomenon that the rebound device fails is caused, so that the working reliability of the carriage cover is improved.
