[0031] The shock absorbing wheel of the embodiment is fixedly arranged at the bottom of the luggage case, comprising a wheel frame 2, the wheel frame 2 is fixedly connected with the bottom of the luggage case, provides a fixed effect for the shock absorbing wheel, the wheel frame 2 is provided with quick release assembly 3, can be connected with connecting rod 1, also can make connecting rod 1 and quick release assembly 3 separate, to realize the quick connection and disassembly of connecting rod 1. The connecting rod 1 of the bottom of the luggage case is arranged along the up and down direction, the upper end of the connecting rod 1 is rotatably connected with the quick release assembly 3, the lower end of the connecting rod 1 is connected with the roller part 4, and the second end 62 of the connecting rod 1 is also provided with a buffer assembly 5, the buffer assembly 5 can make the connecting rod 1 and the roller part 4 movably connected, when the roller 42 passes through the uneven road surface, the roller 42 can move along the first direction under the action of the buffer assembly 5, to reduce the vibration of the luggage case, reduce the noise. When the roller part 4 is worn, it needs to be replaced in time to maintain the continuous use of the luggage case, therefore, the top of the connecting rod 1 and the quick release assembly 3 are detachably connected with each other, to realize the quick replacement of the connecting rod 1 and the roller part 4.
[0032] In one embodiment, as Figure 4 The quick release assembly 3 can be moved along the second direction between the first position and the second position relative to the wheel frame 2, in the first position, the quick release assembly 3 is in contact with the first end 61, to limit the movement of the connecting rod 1 along the first direction, in the second position, the quick release assembly 3 is separated from the first end 61, and the connecting rod 1 can move along the first direction, that is, moving the quick release assembly 3 from the first position to the second position can make the quick release assembly 3 and the connecting rod 1 separate from each other, after installing the new connecting rod 1 to the predetermined position, moving the quick release assembly 3 from the second position to the first position can lock the connecting rod 1 and the quick release assembly 3, to realize the locking of the quick release assembly 3.
[0033] The quick release assembly 3 is oppositely provided with the third end 63 and the fourth end 64 along the second direction.
[0034] In order to avoid the quick release assembly 3 from opening by itself during normal use, and the wheel 42 from falling off due to the mutual separation of the connecting rod 1, a reset assembly is arranged on the wheel frame 2, which can provide a reset force, so that the quick release assembly 3 can always be in the first position, or the quick release assembly 3 in the second position can automatically move to the first position and form a connection with the connecting rod 1. The reset assembly can be a magnetic component or an elastic component.
[0035] Preferably, the reset assembly can be a first type of elastic member 7, which can provide an elastic force by being in a compressed state, for example, a compression spring or a torsion spring. When the first type of elastic member 7 is a compression spring, the compression spring needs to be arranged in the second direction and provide a repulsive force to the third end 63 of the quick release assembly 3, so that the quick release assembly 3 has a tendency to move to the first position or is maintained in the first position.
[0036] Preferably, the reset assembly can be a second type of elastic member 7, which can provide an elastic force by being in a stretched state, for example, a tension spring or a rubber band. The tension spring needs to be arranged in the second direction and provide a pulling force to the fourth end 64 of the quick release assembly 3, so that the quick release assembly 3 has a tendency to move to the first position or is maintained in the first position.
[0037] In one embodiment, as shown in Figure 4 the wheel frame 2 is provided with a first sliding groove 21 in the second direction; the quick release assembly 3 includes a third end 63 and a fourth end 64 arranged opposite to each other in the second direction; at least part of the quick release assembly 3 is accommodated in the first sliding groove 21 and can slide along the first sliding groove 21; an elastic member 7 is arranged inside the first sliding groove 21, one end of the elastic member 7 abuts against the inner wall of the first sliding groove 21, and the other end of the elastic member 7 abuts against the third end 63 of the quick release assembly 3, so that the quick release assembly 3 has a tendency to move to the fourth end 64. When it is necessary to install or dismount the wheel 42, the quick release assembly 3 can be slid along the second direction to the third end 63, and the quick release assembly 3 can slide to the third end 63 against the elastic force of the elastic member 7. When the force acting on the quick release assembly 3 is removed, the quick release assembly 3 will move to the fourth end 64 under the action of the elastic member 7, and the top end of the connecting rod 1 is clamped inside the quick release assembly 3 to realize the connection. The elastic member 7 can also make the quick release assembly 3 always have a tendency to move to the fourth end 64, so as to avoid the quick release assembly 3 from being displaced due to external factors and causing the wheel 42 to fall off.
[0038] In one embodiment, as shown in Figure 7As shown, the quick release assembly 3 comprises a sliding piece 31; the sliding piece 31 is provided with a through hole 32 and a clamping hole 33; the inner diameter of the through hole 32 is larger than that of the clamping hole 33; the clamping hole 33 and the through hole 32 are in communication with each other; when the sliding piece 31 is located at the first position, the first end 61 is located inside the clamping hole 33; when the sliding piece 31 is located at the second position, the first end 61 is located inside the through hole 32. Since the inner diameter of the through hole 32 is larger than that of the clamping hole 33, when the sliding piece 31 is located at the second position, the connecting rod 1 is located inside the through hole 32 and can move freely along the first direction; when the sliding piece 31 is located at the first position, the connecting rod 1 is locked inside the clamping hole 33 and cannot move along the first direction.
[0039] In an embodiment, the quick release assembly 3 further comprises a fixing cover 34, which is fixedly connected with the wheel frame 2 and covers at least the elastic piece 7.
