In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

Referring to fig. 1, the present invention provides a folding member 300 for use in a tray body 400 of a robot. The robot may be a food delivery robot, and the folding member 300 may be disposed on the tray body 400 of the food delivery robot.

Referring to fig. 2, the folding member 300 includes a displacement mechanism 200 and a position-limiting mechanism 100.

The displacement mechanism 200 is capable of being opened and folded. When the shifting mechanism 200 is opened, it is elongated in the preset direction, and when the shifting mechanism 200 is folded, it is shortened in the preset direction. It should be noted that the preset direction may be a height direction of the displacement mechanism 200.

The stopper mechanism 100 is provided on the displacement mechanism 200 and can lock and unlock the displacement mechanism 200. When the position limiting mechanism 100 locks the shifting mechanism 200, the shifting mechanism 200 is positioned in the current state, that is, the shifting mechanism 200 cannot continue to perform the opening or folding action; when the position-limiting mechanism 100 releases the displacement mechanism 200, the displacement mechanism 200 can be freely opened or folded.

Referring to fig. 2 and 3, the limiting mechanism 100 includes a limiting member 10 and a restoring member 20.

The stopper 10 is provided at an upper portion of the displacement mechanism 200, and can lock and unlock the displacement mechanism 200 by moving relative to the displacement mechanism 200. The limiting member 10 is provided with a limiting groove 101 capable of limiting the movement of the displacement mechanism 200. It can be understood that the limiting member 10 can move relative to the displacement mechanism 200 and lock or unlock the displacement mechanism 200 by moving to different positions, when the limiting member 10 is located at the locking position, the limiting member 10 can lock the displacement mechanism 200, and at this time, the displacement mechanism 200 is at least partially located in the limiting groove 101, and at least one groove wall of the limiting groove 101 can limit the displacement mechanism 200 to move. In the present embodiment, the movement of the limiting member 10 relative to the shifting mechanism 200 may be driven by manual force application. In other embodiments, the motion of the limiting member 10 can be driven by an electric force or other mechanical structure.

The reset member 20 is disposed between the limiting member 10 and the shifting mechanism 200, and is used for providing a reset force for the limiting member 10. After the limiting member 10 is away from the locking position, the resetting member 20 can apply a resetting force to the limiting member 10, and the limiting member 10 can be returned to the locking position under the action of the resetting force. In this embodiment, when the limiting element 10 is located at the locking position, the limiting element 10 limits the movement of the shifting mechanism 200 through the limiting groove 101, so as to lock the shifting mechanism 200, at this time, the shifting mechanism 200 is opened, after the limiting element 10 moves relative to the shifting mechanism 200, the limiting element 10 releases the shifting mechanism 200, the shifting mechanism 200 is freely folded, at this time, the resetting mechanism applies a resetting force to the limiting element 10, and the limiting element 10 returns to the locking position under the action of the resetting force. In other embodiments, when the limiting member 10 locks the shifting mechanism 200, the shifting mechanism 200 may also be in a folded state, which is not limited in this application and may be reasonably set according to actual needs.

This folding component 300 has realized locking or relaxing to displacement mechanism 200 through stop gear 100 for displacement mechanism 200 can not appear the condition of rocking, guarantees that the article of placing in displacement mechanism 200 can be stable, avoids appearing the condition that article splashed. The limiting mechanism 100 locks the shifting mechanism 200 through the limiting groove 101 formed in the limiting member 10, so that the shifting mechanism 200 stays in the current state stably, and the shifting mechanism 200 is prevented from deforming. The limiting mechanism 100 can also release the shifting mechanism 200 by moving the limiting member 10 relative to the shifting mechanism 200, so that the shifting mechanism 200 can be freely opened or folded, and the limiting member 10 can automatically reset under the action of the resetting force of the resetting member 20 without the assistance of external force, thereby saving operation. When the folding member 300 is used, an operator only needs to toggle the position-limiting piece 10 to move, so that the shifting mechanism 200 can be locked or loosened, and the operation is convenient and fast.

Referring to fig. 2 and 3, the displacement mechanism 200 includes a support base 210, a driving member 220 and a sliding shaft 230, wherein the driving member 220 is slidably connected to the support base 210 through the sliding shaft 230, and the support base 210 is driven to move up and down by the sliding of the sliding shaft 230 relative to the support base 210. Thus, the shifting mechanism 200 can be opened or folded by sliding the sliding shaft 230 relative to the supporting seat 210, the supporting seat 210 can be driven to ascend when the shifting mechanism 200 is opened, and the supporting seat 210 can be driven to descend when the shifting mechanism 200 is folded. The support base 210 has a mounting surface 2101, a sliding rail 211 is disposed on the mounting surface 2101, and the sliding shaft 230 is slidably connected to the sliding rail 211. The extending path of the slide rail 211 is a sliding path of the slide shaft 230. The driving member 220 can be deformed telescopically, and when the driving member 220 is extended, the displacement mechanism 200 is opened, and when the driving member 220 is contracted, the displacement mechanism 200 is folded.

In the present embodiment, please refer to fig. 3 and fig. 4, the position-limiting member 10 is rotatably connected to the supporting base 210. Specifically, the limiting member 10 is rotatably connected to the mounting surface 2101, and the rotation axis of the limiting member 10 is perpendicular to the mounting surface 2101. The limiting member 10 can rotate from a locking position to a releasing position in a first direction a or from the releasing position to a locking position in a second direction b opposite to the first direction a relative to the supporting seat 210. As shown in fig. 3, in the present embodiment, the first direction a is a clockwise direction, and the second direction b is a counterclockwise direction. The lock position is a specific position, and the disengagement position is an arbitrary position away from the lock position in the first direction a.

The limiting groove 101 is adapted to the sliding shaft 230, and when the position-limiting member 10 locks the displacement mechanism 200, the sliding shaft 230 is at least partially located in the limiting groove 101. When the sliding shaft 230 is located in the limiting groove 101, the two side groove walls of the limiting groove 101 can respectively limit the sliding shaft 230 to slide along the sliding track 211, so as to limit the driving member 220 from being deformed in a stretching manner, and thus, the shifting mechanism 200 can be locked in the current state.

Specifically, the notch of the limiting groove 101 faces the second direction b, and the limiting groove 101 has at least two opposite groove walls perpendicular to the mounting surface 2101 or substantially perpendicular to the mounting surface 2101. When the limiting member 10 rotates to the locking position, the sliding shaft 230 can be at least partially received in the limiting groove 101, and when the limiting member 10 is in the locking position, two groove walls of the limiting groove 101 can respectively limit the sliding shaft 230 to move towards two ends of a sliding path of the sliding shaft 230. It can be understood that when the supporting seat 210 moves to the predetermined position, the sliding shaft 230 can slide on the sliding path thereof to the position to be locked, and the sliding shaft 230 is located on the rotating path of the limiting groove 101. When the limiting member 10 rotates to the locking position, the sliding shaft 230 can slide into the limiting groove 101, or partially slide into the limiting groove 101, and at this time, the groove walls on both sides of the limiting groove 101 are respectively located on both sides of the sliding shaft 230 and both located on the sliding path of the sliding shaft 230, so as to form two blocking surfaces for limiting the sliding of the sliding shaft 230 towards both ends of the sliding path. The limiting groove 101 can be adapted to the sliding shaft 230, so that the sliding shaft 230 is limited at the current position to be locked, and the supporting seat 210 is prevented from shaking.

The limiting member 10 can also rotate towards the disengaging position relative to the supporting seat 210, so that the sliding shaft 230 disengages from the limiting groove 101 and slides along the sliding path. Specifically, the limiting member 10 can rotate toward the first direction a to a disengaged position, when the limiting member 10 is located at the disengaged position, the sliding shaft 230 is disengaged from the limiting groove 101 and located outside the limiting groove 101, the groove walls on two sides of the limiting groove 101 no longer limit the sliding of the sliding shaft 230 on the sliding path, and the sliding shaft 230 can leave the position to be locked, so that the driving member 220 drives the supporting seat 210. The disengagement position is an arbitrary position at which the stopper 10 does not affect the sliding of the slide shaft 230.

In other embodiments, the position-limiting member 10 can also translate relative to the supporting seat 210.

The restoring element 20 is connected to the limiting element 10, or the restoring element 20 is connected to the supporting base 210, or the restoring element 20 is connected to the limiting element 10 and the supporting base 210. The reset member 20 is capable of providing a reset force to return to the locking position when the limiting member 10 is away from the locking position. That is, when the limiting member 10 moves to the disengagement position, the resetting member 20 can apply a resetting force to the limiting member 10, so that the limiting member 10 is returned to the locking position.

In a natural state, the limiting member 10 is always in the locking position under the action of the resetting force of the resetting member 20. When the supporting seat 210 needs to be locked at the preset position, the limiting member 10 can be rotated to the disengaging position in the first direction a by external force, then the driving member 220 drives the supporting seat 210 to move to the preset position, at this time, the sliding shaft 230 moves to the position to be locked relative to the supporting seat 210, then the external force is removed, the limiting member 10 can return to the locking position under the action of the resetting force of the resetting member 20, at this time, the sliding shaft 230 is located in the limiting groove 101, so that the limiting mechanism 100 can limit the sliding shaft 230, and the supporting seat 210 is limited at the current preset position.

When the sliding shaft 230 needs to be unlocked, the limiting member 10 can be rotated to the disengagement position toward the first direction a by an external force, and at this time, the sliding shaft 230 disengages from the limiting groove 101 and can slide along the sliding path thereof to a position away from the position to be locked. So that the driving member 220 can drive the supporting seat 210 to move. When the external force is removed, the limiting member 10 is returned to the locking position by the restoring force of the restoring member 20. The limiting mechanism 100 unlocks the sliding shaft 230, so that the supporting seat 210 can move freely under the action of the driving element 220.

The external force may be an external force applied manually or an external force applied to the stopper 10 by a mechanical structure.

In the embodiment, the reset element 20 has elasticity and is respectively connected to the limiting element 10 and the supporting base 210, and the reset element 20 can be elastically deformed when the limiting element 10 is away from the locking position, so as to provide an elastic reset force for returning the limiting element 10 to the locking position. Thus, after the limiting member 10 is away from the locking position and the external force is removed, the limiting member 10 can automatically return to the locking position under the action of the elastic restoring force. Specifically, the reset element 20 may be a torsion spring sleeved on the hinge shaft 12, and two extending ends of the torsion spring respectively abut against the limiting element 10 and the supporting seat 210. Wherein, the restoring member 20 may also be a spring or a rubber strip.

In other embodiments, the restoring element 20 may also be a magnetic element, and can apply a magnetic attraction force or a magnetic repulsion force to the limiting element 10 when the limiting element 10 moves away from the locking position. Alternatively, the restoring element 20 may be connected to the limiting element 10 only, and may have a magnetic attraction force with the supporting base 210.

Like this the distance between spacing groove 101 and the articulated shaft 12 is great, and when locating part 10 rotated around articulated shaft 12, spacing groove 101 around articulated shaft 12 circular motion, compare in with spacing groove 101 set up in the position nearer apart from articulated shaft 12, locate spacing groove 101 and be close to second end 104 and can reduce required pivoted angle under the condition of removal equidistance, reduced operating time and operating dynamics of operating personnel, realized stop gear 100's quick unblock. In the present embodiment, when the limiting member 10 is in the locking position, the extending direction of the limiting plate 11 is the same as the extending direction of the sliding path of the sliding shaft 230.
