The panel of the rack 120 is provided with an opening 121 for a user to pick up goods, and the shape of the opening 121 is not limited, and may be, for example, a square shape, a circular shape, an irregular shape, or the like.

In this embodiment, the opening 121 may have a rectangular structure, specifically, the opening 121 may be surrounded by a plurality of frames, in this embodiment, please refer to fig. 2, the opening 121 is surrounded by a first frame 122, a second frame 123, a third frame 124 and a fourth frame 125, the first frame 122 and the second frame 123 are arranged at intervals relatively along a first direction, and the third frame 124 and the fourth frame 125 are arranged at intervals relatively along a second direction, where the first direction may be a horizontal direction, and the second direction may be a vertical direction, and the like. The first frame 122 is located above the second frame 123, the first frame 122, the second frame 123, the third frame 124 and the fourth frame 125 are distributed in a rectangular shape, and the first frame 122 can be used as a mounting frame.

The opening 121 is controlled to open and close by a gate 130, wherein the gate 130 is movably connected with the frame 120, and the movable connection mode can be a rotating connection, a sliding connection, and the like.

The shutter 130 has an open position and a closed position, and the shutter 130 is movable between the open position and the closed position, the opening 121 being opened when the shutter 130 is in the open position, and the opening 121 being closed when the shutter 130 is in the closed position.

In the present embodiment, the gate 130 is slidably connected to the frame 120, that is, the gate 130 is slidable relative to the frame 120, and the sliding direction of the gate 130 relative to the frame 120 is not limited, and may be, for example, opened and closed in the left-right direction, opened and closed in the up-down direction, opened and closed in an inclined lifting manner, or the like.

In this embodiment, the gate 130 is slidably disposed on the frame 120 along the vertical direction, when the gate 130 rises to the highest point, the opening 121 is closed by the gate 130, so that the vending machine is in a closed state, when the gate 130 descends to the lowest point, the opening 121 is not covered by the gate 130, and a user can take goods through the opening 121; alternatively, when the shutter 130 ascends to the highest point, the opening 121 is opened, and when the shutter 130 descends to the lowest point, the opening 121 is closed.

The shutter 130 may be a plate-like structure, and the shape of the shutter 130 matches the opening 121, and generally, the area of the shutter 130 is slightly larger than that of the opening 121, that is, the shutter 130 can completely block and close the opening 121.

The gate 130 may include a front end 136 and a rear end 137, the front end 136 being downstream of the rear end 137 in the direction of movement of the gate 130 to the closed position. When the gate 130 is in the open position, the first rim 122 is opposite the front end 136 of the gate 130.

The movement of the gate 130 is driven by a linear driving mechanism 131, the linear driving mechanism 131 can be controlled by a control component of the vending machine, and the specific structure of the linear driving mechanism 131 can adopt but is not limited to the following scheme:

as shown in fig. 1 and 3, the linear driving mechanism 131 includes a motor 132, a first pulley 133, a second pulley 134, and a transmission belt 135.

The first pulley 133 and the second pulley 134 are disposed at an interval on the frame 120 along an opening and closing direction of the shutter 130 (a direction in which the shutter 130 opens the opening 121, or a direction in which the shutter 130 closes the opening 121), and both the first pulley 133 and the second pulley 134 are rotatable. In the present embodiment, the first pulley 133 is located directly below the second pulley 134, and the center lines of the first pulley 133 and the second pulley 134 are parallel.

The driving belt 135 is respectively sleeved on the first pulley 133 and the second pulley 134, the driving belt 135 is fixedly connected with the gate 130, and the fixing manner of the driving belt 135 and the gate 130 is not limited, for example, the driving belt 135 can be directly fixed or indirectly connected through a connecting member.

The motor 132 is mounted on the frame 120, an output shaft of the motor 132 is in transmission fit with the first belt pulley 133 or the second belt pulley 134, in this embodiment, the output shaft of the motor 132 is in transmission connection with the first belt pulley 133, the motor 132 is in indirect transmission with the second belt pulley 134, and the motor 132 adopts a forward and reverse motor 132, that is, the motor 132 can rotate forward and reverse.

The motor 132 works under the action of a power supply and a control component (the power supply and the control component can be independently arranged and can also be uniformly controlled by the vending machine), and can drive the first belt wheel 133 and the second belt wheel 134 to rotate, the driving belt 135 rotates under the combined action of the first belt wheel 133 and the second belt wheel 134, so that the gate 130 can be driven to ascend or descend, for example, when the first belt wheel 133 rotates forwards, the driving belt 135 drives the gate 130 to ascend, and when the first belt wheel 133 rotates backwards, the driving belt 135 drives the gate 130 to descend, so that the gate 130 is driven to move between an opening position and a closing position.

In other embodiments, if the shutter 130 is opened and closed in the left-right direction, the first pulley 133, the second pulley 134, and the transmission belt 135 may be disposed in the transverse direction, when the first pulley 133 rotates forward, the transmission belt 135 drives the shutter 130 to slide leftward (or slide rightward), when the first pulley 133 rotates backward, the transmission belt 135 drives the shutter 130 to slide rightward (or slide leftward), and so on.

The linear driving mechanism 131 is disposed inside the frame 120, and in other embodiments, the linear driving mechanism 131 may further adopt a rack-and-pinion transmission mechanism or a lead screw nut transmission mechanism, and such a structure may refer to the prior art and is not described herein again.

For the structure of the frame 120 and the shutter 130, reference may be made to the prior art.

The rack 120 and the gate 130 realize the basic function of picking up goods, that is, the opening 121 is opened and closed, and before and during the closing of the gate 130 to the opening 121, whether an obstacle, such as a hand of a user or goods, exists in the opening 121 is detected by the detection component 140, so as to determine whether the gate 130 can be continuously closed.

The number of the detecting elements 140 is not limited, for example, the number of the detecting elements 140 is one, two, three, etc., and in the present embodiment, the number of the detecting elements 140 is one.

Referring to fig. 3 to 5, the detecting assembly 140 is disposed on the rack 120 or the gate 130, the detecting assembly 140 includes a detecting member 141 and a triggering member 142, the triggering member 142 has an initial position and a triggering position, and the triggering member 142 can move between the initial position and the triggering position relative to the detecting member 141.

If there is an obstruction within the opening 121, the shutter 130 is blocked during its movement to the closed position, and the blocking means includes two types: firstly, the detection component 140 is arranged on the gate 130, when the gate 130 moves to the closed position, the trigger 142 is blocked by the hand or other obstacles of the user and cannot advance; second, the detection component 140 is disposed on the rack 120, when the shutter 130 moves to the closed position, the shutter 130 continues to advance after contacting the hand or other obstacle of the user, and at this time, the hand or other obstacle of the user obstructs the closing of the shutter until the hand or other obstacle of the user contacts the trigger and moves the trigger to the trigger position.

The term "resistance" in this embodiment means that the resistance received exceeds a predetermined resistance threshold. When the trigger 142 is not blocked or the resistance applied to the trigger 142 is smaller than the preset resistance threshold, the trigger 142 is always located at the initial position; when the resistance force applied to the shutter 130 during the movement to the closed position exceeds a preset resistance threshold value, the trigger 142 can move from the initial position to the trigger position.

The preset resistance threshold refers to a preset resistance value, and the size of the preset resistance threshold can be set according to needs, for example, 1N, 10N, and the like.

When the trigger 142 moves to the trigger position, the trigger 142 can trigger the detector 141 to generate a signal for stopping the movement of the shutter 130. The control mechanism determines that there is an obstacle in the opening 121 according to the signal, and controls the motor 132 to stop at the same time, so that the shutter 130 cannot move any further.

The structure of the trigger 142 can adopt but is not limited to the following schemes: as shown in fig. 6, the trigger 142 includes a plate 143, a trigger portion 144, and a detection portion 145, the plate 143 is used as a main structure of the trigger 142, the trigger portion 144 is used for contacting an obstacle, and the detection portion 145 is used for cooperating with the detection member 141.

Referring to fig. 7, the plate 143 is slidably connected to the frame 120 or the gate 130, and the trigger part 144 is formed by bending one end of the plate 143, and the bending form is not limited, for example, the trigger part may be bent or folded, and thus, the strength and the surface smoothness of the trigger 142 may be increased, and the user's hand or goods may be prevented from being scratched by the burr of the trigger part 144.

The detecting unit 145 is located on the plate 143, and the detecting unit 145 moves with the plate 143 and is movably engaged with the detecting member 141.

In this embodiment, the plate 143 includes a first plate 146, a second plate 147 and a third plate 148 sequentially connected at an included angle, the first plate 146 is slidably connected to the gate 130 or the frame 120, the trigger portion 144 is disposed on the first plate 146, and the detection portion 145 is disposed on the third plate 148.

Preferably, the second plate 147 may be formed by bending one end of the first plate 146, and the third plate 148 may be formed by bending one end of the second plate 147.

The detecting part 145 is located downstream of the triggering part 144 in the direction of the triggering part 142 moving to the triggering position, preferably, the triggering part 144 and the detecting part 145 are respectively located at two ends of the triggering part 142 in the moving direction thereof, and in other embodiments, the detecting part 141 and the triggering part 144 may be located at the same end of the triggering part 142 in the moving direction thereof.

Referring to fig. 7-9, if the detecting component 140 is disposed on the gate 130, the triggering component 142 extends from the front end 136 when located at the initial position; if the detecting assembly 140 is disposed on the frame 120, the triggering member 142 extends from the mounting frame when it is located at the initial position.

The extending direction of the trigger part 144 is parallel to the extending direction of the first frame 122, and the length of the trigger part 144 along the extending direction thereof is matched with the length of the first frame 122 along the extending direction thereof; alternatively, the extension direction of the trigger 144 is parallel to the extension direction of the front end 136 of the shutter 130, and the length of the trigger 144 in the extension direction thereof is adapted to the length of the front end 136 of the shutter 130 in the extension direction thereof. The arrangement is such that when the gate 130 is moved to the closed position, an obstacle located within the opening can reliably trigger the trigger 142, thereby improving the reliability of the anti-pinch function of the gate mechanism 12.

When the trigger 142 is at the initial position, the detecting part 145 is separated from the detecting part 141, and when the trigger 142 is at the trigger position, the detecting part 145 is engaged with the detecting part 141 and triggers the detecting part 141 to send a signal for stopping the movement of the shutter 130.

The triggering member 142 is capable of moving vertically relative to the detecting member 141, and if the detecting member 140 is disposed on the shutter 130, the initial position is located downstream of the triggering position in the direction of movement of the shutter 130 to the closed position; if the detection assembly 140 is disposed in the housing, the trigger position is located downstream of the initial position in the direction of movement of the gate 130 toward the closed position.

In this embodiment, the structure of the detecting member 141 can adopt, but is not limited to, the following scheme: the detecting member 141 includes a sensor (e.g., a photo sensor, etc.) having a U-shape, and the sensor includes a transmitter and a receiver that are matched with each other. When the trigger 142 is in the initial position, the detecting part 145 withdraws from the detecting part 141, the transmitter and the receiver are not obstructed, the sensor can output a first signal, the control mechanism receives the first signal and judges that no obstacle exists in the opening 121, and the gate 130 can be closed; when the trigger 142 is located at the trigger position, the detection part 145 enters between the transmitter and the receiver, the transmitter and the receiver are blocked, the sensor outputs a second signal, the control mechanism receives the second signal and accordingly judges that an obstacle exists in the opening 121, the gate 130 cannot be closed continuously, and at the moment, the control mechanism controls the motor 132 to stop running, and the gate 130 stops moving.

The detection assembly 140 may be mounted in, but is not limited to, one of the following ways:

if the trigger 142 is maintained at the initial position by its own weight, and the initial position is located below the trigger position, the trigger 142 has a tendency to move toward the initial position under its own weight. This solution can derive the following first solution and second solution (in the first solution and the second solution, the triggering member 142 is maintained at the initial position by its own weight), and the specific structure is as follows:

in a first solution (not shown in the drawings), the detecting component 140 is disposed at the bottom of the gate 130, the detecting element 141 is fixed to the gate 130, the triggering element 142 is connected to the gate 130 in a liftable manner, the triggering portion 144 extends out from the bottom of the gate 130, the gate 130 is closed in a direction from top to bottom, and the triggering element 142 always has a tendency of moving downward under the action of its own gravity. When the gate 130 is located at the opening position and the trigger 142 is located at the initial position, the trigger portion 144 is vertically higher than the second rim 123, so that when the gate 130 opens the opening 121, the trigger portion 144 of the trigger 142 does not occupy the space of the opening 121, and when the article is taken out from the opening 121, the article does not touch the trigger portion 144 and can be smoothly taken out.

If the trigger 142 is maintained at the initial position by the elastic member 149, the elastic member 149 is disposed between the trigger 142 and the shutter 130 or the elastic member 149 is disposed between the trigger 142 and the frame 120 so that the trigger 142 tends to move toward the initial position, a mounting plate 138 may be disposed on the shutter 130 or the frame 120, one end of the elastic member 149 is connected to the mounting plate 138, and the other end is connected to the second plate 147, but the detecting member 141 may be mounted on the mounting plate 138 and the mounting plate 138 is spaced apart from the second plate 147. This solution can derive the following third, fourth, fifth and sixth solutions (in the third, fourth, fifth and sixth solutions, the triggering member 142 is maintained at the initial position by the elastic member 149), and the specific structure is as follows:

When the gate 130 is located at the opening position and the trigger 142 is located at the initial position, the trigger portion 144 is vertically lower than the second frame 123, so that when the gate 130 opens the opening 121, the trigger portion 144 of the trigger 142 does not occupy the space of the opening 121, and when the object is taken out from the opening 121, the object does not touch the trigger portion 144 and can be smoothly taken out.
