Please refer to FIG. 5 and FIG. 6 . FIG. 5 is a perspective view showing the wheel set 120 in the adduct position according to the embodiment of FIG. 1 , and FIG. 6 is a view showing the wheel set 120 in the embodiment according to the first embodiment. Another perspective of the receiving position. In FIGS. 3 and 4, the axle 121 is abutted by the positioning member 153 and positioned at the exposed position. As can be seen from FIGS. 5 and 6, when the pressing member 152 is forced to move along the axial direction A1 of the lever 151. When the positioning member 153 is abutted, the positioning member 153 is displaced along the axial direction A1 of the rod 151 and disengages from the abutting end 124 of the wheel set 120, and the wheel set The 120 is driven by the restoring force of the elastic member 140 to cause the wheel set 120 to shift to the retracted position.

That is, the user can apply force to the pressing member 152 to release the abutment of the positioning member 153 and the wheel set 120, and the wheel set 120 is received into the accommodating space 111. More specifically, referring to FIG. 4 again, the pressing member 152 is sleeved on one end of the rod 151 and exposed to the end of the housing 110 for the user to press the force, and one end of the pressing member 152 abuts against the top positioning member 153. One side.

Specifically, the positioning group 150 may further include a positioning spring 155, the positioning spring 155 is connected to the rod 151, and is used for the first restoring force of the positioning element 153 to position the positioning element 153 in the positioning position, wherein the positioning position is the third position. The position of the positioning member 153 in the figure and Fig. 4 is shown. When the pressing member 152 is forced along the axial direction A1 of the rod 151, the pressing member 152 is urged toward the positioning member 153 in the direction of the positioning spring 155 along the axial direction A1 of the rod member 151, and the positioning member 153 is displaced toward the positioning spring 155, and The positioning spring 155 is compressed to disengage the positioning member 153 from the abutment of the abutment 124 of the axle 121. When the abutting end 124 of the axle 121 is not abutted by the positioning member 153, that is, the elastic member 140 is also not twisted by the positioning member 153, the elastic member 140 releases and provides a restoring force to the axle 121, and the abutment 124 of the axle 121 When the elastic member 140 is driven, the axle 121 is rotated by the pivoting shaft 130 to drive the wheel base 122 and the wheel body 123 to be displaced into the accommodating space 111, so that the wheel set 120 is located at the retracting position, that is, the folding wheel assembly 100 is completed. fold.

In addition, the positioning group 150 may further include a limiting bolt 154, and the limiting bolt 154 is disposed in the rod member 151 in a direction perpendicular to the axial direction A1 of the rod 151, thereby limiting the force when the pressing member 152 is displaced and displaced. Position pin 154 can limit the pressing piece The extent of 152 displacement. The positioning spring 155 is sleeved on the rod 151, one end of the positioning spring 155 abuts the top housing 110, and the other end of the positioning spring 155 abuts the other side of the positioning element 153. In detail, the pressing member 152 pushes against the positioning member 153 in the direction of the positioning spring 155 along the axial direction A1 of the lever member 151, displaces the positioning member 153 toward the positioning spring 155, and compresses the positioning spring 155, and is supported by the limit pin 154. The card abuts against the top groove 1521 of the pressing member 152 to limit the degree of displacement of the pressing member 152.

The folding wheel assembly 100 further includes a limiting rod member 161 and a limiting spring 162. The limiting rod member 161 is disposed on the housing 110, the limiting spring 162 is connected to the limiting rod member 161, and one end of the limiting spring 162 is connected. The positioning component 153 is configured to provide a second restoring force to the positioning component 153 to position the positioning component 153 at the positioning position.

With the above configuration, when the positioning member 153 abuts the top axle 121, the positioning member 153 is subjected to the first restoring force of the positioning spring 155 and the second restoring force of the limiting spring 162 to maintain the positioning member 153 in the positioning position. The positioning member 153 is more reliably abutted against the axle 121 and increases the stability of the folding wheel assembly 100.

Further, when the pressing member 152 is pushed against the positioning member 153, as shown in Fig. 5, the positioning member 153 is disengaged from the axle 121, and the positioning member 153 compresses the positioning spring 155.
