The transition process between the installed state and the opened state of the guide assembly 100 in this embodiment will be described below with reference to FIGS. 6a to 6c and 7a to 7b.

When the guide assembly 100 is in the installed state, the swinging bottom 22 is basically maintained at a horizontal position; as can be seen from FIG. 6B, the swinging bottom 22 is abutted on the bottom plate 45, and the first arcuate surface 222 of the first latching portion 221 and the first The second arc-shaped surfaces 311 of the two latching portions 31 are snap-contacted. Due to the elastic force of the first spring 37, the second engaging portion 31 catches the first engaging portion 221 and prevents the swinging block 2 from turning over. It can be seen from FIG. 6c that there is a certain moving space between the swing block 2 and the fourth plate 422 for the swing block 2 to telescopically move. At this time, as shown in FIG. 7a, the first inclined surface 461 is in contact with the fourth inclined surface 252. Under the elastic action of the second spring 28, the fourth inclined surface 252 has a tendency to move relative to the first inclined surface 461, that is, the swinging block 2 has a tendency to rotate clockwise (the clockwise direction is based on the perspective of FIG. 6a).

Applying force to the swinging side portion 21 to turn the swinging block 2 counterclockwise, the first latching portion 221 applies a force to the second latching portion 31, so that the elastic block 3 moves backward against the force of the first spring 37 until the first The two latching portions 31 no longer catch the first latching portion 221. At the same time, as shown in FIG. 7a, when the swing block 2 is reversed, due to the interaction between the fourth inclined surface 252 and the first inclined surface 461, the swing block 2 moves along the axial direction of the first rotation axis 27, that is, the swing block 2 moves The first rotating shaft 27 is moved axially to the right by a certain distance, and accordingly the second spring 28 is compressed.

Continue to apply force to the swinging side portion 21 to flip the swinging block 2. As shown in FIG. 7 b, the swinging block 2 will be separated from the fourth inclined surface 252 and the first inclined surface 461, and the third inclined surface 251 and the second inclined surface 462 are not in contact. In the critical position, at this time, the space between the swing block 2 and the fourth plate 422 is reduced to a minimum, and the second spring 28 is compressed and deformed to the maximum position. When the swing block 2 passes the critical position, the second spring 28 starts a return movement Under the elastic action of the second spring 28, as shown in FIG. 7c, the third inclined surface 251 moves along the second inclined surface 462, thereby driving the swinging block 2 to automatically turn counterclockwise into place. At this point, the guide assembly 100 is turned on. status.

When the guide assembly 100 is in the open state, the swinging bottom 22 is basically in a vertical position. At this time, a force is applied to the swinging bottom 22 to turn the swinging block 2 clockwise. As shown in FIG. 7c, when the swing block 2 is reversed, due to the interaction of the third inclined surface 251 and the second inclined surface 462, the reversing motion of the swing block 2 is accompanied by the axial movement of the swing block 2 along the first rotation axis 27, That is, the swing block 2 moves a certain distance to the right along the axial direction of the first rotation axis 27, and accordingly the second spring 28 is compressed.

Continue to apply force to the swing bottom 22 to flip the swing block 2. As shown in FIG. 7b, the swing block 2 will be at a critical point where the third inclined surface 251 is separated from the second inclined surface 462, and the fourth inclined surface 252 and the first inclined surface 461 are not yet in contact. position. At this time, the space between the swing block 2 and the fourth plate 422 is reduced to a minimum, and the second spring 28 is compressed and deformed to a maximum position. When the swing block 2 crosses this critical position, the second spring 28 starts to return. Under the elastic action of the second spring 28, as shown in FIG. 7a, the fourth inclined surface 252 moves along the first inclined surface 461, thereby driving the swing block 2 Automatically flip until the first engaging portion 221 of the swinging block 2 is caught by the second engaging portion 31 of the elastic block 3 and cannot be inverted. At this time, a force is applied to the roller 38 to move the elastic block 3 backward until the second latching portion 31 no longer catches the first latching portion 221. Then, the swinging block 2 will automatically flip under the action of the second spring 28 In place. After the biasing force on the roller 38 is released, the elastic block 3 will be reset by the action of the first spring 37, and the second latching portion 31 will catch the first latching portion 221 to prevent the swinging block 2 from turning over. At this point, the guide assembly 100 In the installed state.

The guide assembly shown in Figs. 1 to 6c can have the following beneficial effects:

1. The arrangement of the first spring 37 allows the elastic block 3 to move back and forth, so that the second latching portion 31 provided on the elastic block 3 can be regarded as an elastic latching portion, and can be elastically elasticized through the second latching portion 31. The displacement of the block 3 causes the first engaging portion 221 and the second engaging portion 31 to be engaged or disengaged.

2. The roller 38 can be used as a force bearing portion provided on the elastic block 3. The external force can be applied to the roller 38 to drive the elastic block 3 to move backward, so that the first engaging portion 221 and the second engaging portion 31 are released from the engaging. The bearing portion may have other structures, for example, it may be a protruding portion fixed on the elastic block 3. It should be understood that the elastic block 3 can be moved backward by squeezing the first latching portion 221 and the second latching portion 31 with each other, and the first latching portion 221 and the second latching portion 31 can be released from the latching.

3. The front face of the first plate 411 and the third plate 421 of the fixed bracket body 4 can be used as the bracket side portion 40 to form the rear wall of the guide groove 101; the interval between the first plate 411 and the third plate 421 A slot can be formed on the rear wall of the guide groove 101. At least a part of the roller 38 can pass through the slot and protrude from the rear wall of the guide groove 101 by the elastic force provided by the first spring 37, so as to apply a force to the roller 38. The force causes the elastic block 3 to move backward until the second engaging portion 31 no longer catches the first engaging portion 221.

4. When the guide assembly 100 is in the installed state, the roller 38 protruding from the rear wall of the guide groove 101 can contact the movable door, and the roller 38 can rotate about the second rotating shaft 36 extending in the up-and-down direction, so that the During the process of the guide groove 101 moving back and forth from side to side, the roller 38 can be in rolling contact with the movable door to reduce the friction between the movable door and the roller 38 and improve the smoothness of the movement of the movable door.
