[0032] Currently, vending machines have received widespread praise because they do not require staff and can operate 24 / 7, thus better meeting customer needs.

[0033] In related technologies, vending machines often use a pusher to dispense goods. To control the pusher's travel and prevent collisions with other structures, switches are typically installed at both the initial and final positions of the pusher. When the pusher reaches the corresponding position, the switch is triggered, shutting off the motor. This not only results in more components but also requires the motor to be started and stopped multiple times, increasing the cost of the vending machine.

[0034] Please see Figures 1-7 To address the issue of high costs associated with existing vending machines, this application provides a dispensing mechanism 100 that can be used in vending machines to dispense goods sold within the machine, thereby meeting sales demands.

[0035] like Figure 3 As shown, the dispensing mechanism 100 includes a support 10, a drive assembly 20, and a transmission assembly 30. The drive assembly 20 is mounted on the support 10, and the transmission assembly 30 is connected to the drive assembly 20 and can move under the drive of the drive assembly 20. The transmission assembly 30 is used to push the goods away from the support 10. When the transmission assembly 30 moves to its limit in the direction of goods ejection under the drive of the drive assembly 20, the transmission assembly 30 can automatically turn and reset.

[0036] Understandably, when the transmission assembly 30 moves to its limit in the direction of goods ejection under the drive assembly 20, the goods are successfully ejected. Afterward, the transmission assembly 30 can automatically reverse direction and move back to its initial state under the drive assembly 20. Furthermore, since the transmission assembly 30 can automatically reverse direction, there is no need for additional switches to limit its movement, thereby reducing the number of parts and lowering costs.

[0037] Specifically, the drive assembly 20 includes a screw 21, the transmission assembly 30 includes a slider unit 31 and a pusher block 32, the bracket 10 has a receiving cavity 101 and a first sliding groove 102, the screw 21 is installed in the receiving cavity 101 and can rotate relative to the bracket 10, the slider unit 31 is sleeved on the outer periphery of the screw 21 and is connected to the screw 21 in a transmission manner. The pusher block 32 includes a main body 321 and a connecting part 322. The main body 321 is located outside the receiving cavity 101 and is used to push the goods away from the bracket 10. One end of the connecting part 322 is connected to the main body 321, and the other end extends into the receiving cavity 101 through the first sliding groove 102 and is connected to the slider unit 31. The screw 21 is provided with a double helical groove 2101. The two helical grooves on the double helical groove 2101 have opposite directions of rotation. Part of the slider unit 31 is inserted into the double helical groove 2101. As the screw 21 rotates, the slider unit 31 can reciprocate along the double helical groove 2101 to drive the push block 32 to move.

[0038] Among them, push block 32 has the following characteristics: Figure 1 The initial state shown and as Figure 2 In the ejection state shown, the support 10 has an ejection end 104. When the pusher 32 is in the initial state, the goods are located on the side of the main body 321 near the ejection end 104 and are stacked on top of the support 10. Subsequently, as the pusher 32 moves, the main body 321 can push the bottommost goods to move. When the pusher 32 moves to the position of the ejection state, the goods can smoothly detach from the support 10 through the ejection end 104.

[0039] This application utilizes a double helical groove 2101 on the screw 21. Since the two helical grooves on the double helical groove 2101 rotate in opposite directions, when the slider unit 31 moves to its limit along one of the helical grooves, the push block 32 is in the ejected state, and the goods are smoothly ejected. Afterward, the slider unit 31 can automatically reverse direction and be reset by moving along the other helical groove, driving the push block 32 to its initial state. That is, throughout the entire process of the push block 32's movement, the screw 21 remains rotating, making the movement of the push block 32 smoother and effectively improving the delivery efficiency. Furthermore, on the one hand, there is no need to set up an additional switch for limiters, thereby reducing the number of parts and lowering costs; on the other hand, there is no need for hardware control to reverse the push block 32, further reducing the cost of the delivery mechanism 100.

[0040] In other embodiments, the automatic reversing of the transmission assembly 30 can also be achieved by means of forward and reverse rotation of the motor, elastic element engagement, and magnetic engagement.

[0041] Here, the extension direction of the screw 21 and the extension direction of the first chute 102 are both the direction of pushing out the goods.

[0042] To further improve the stability of the pusher block 32's movement, in one embodiment, such as Figure 1 and Figure 4 As shown, the bracket 10 also has a second slide groove 103, and the push block 32 further includes a sliding protrusion 323. One end of the sliding protrusion 323 is connected to the main body 321, and the other end extends into the second slide groove 103 and abuts against the bottom wall of the second slide groove 103. Similarly, the extension direction of the second slide groove 103 is also the direction of pushing out the goods, but the second slide groove 103 is not connected to the receiving cavity 101. In this way, during the movement of the push block 32, the sliding protrusion 323 and the second slide groove 103 form a linear contact, thereby improving the straightness of the push block 32's movement.

[0043] Specifically, the number of the second groove 103 and the sliding protrusion 323 can be set to multiple, and they are set in a one-to-one correspondence. This helps to further improve the straightness of the movement of the push block 32. The sliding protrusion 323 can be set to a hemispherical or semi-cylindrical shape, etc., and can be reasonably set according to actual needs.

[0044] Similarly, the number of the first slide groove 102 and the connecting part 322 can also be multiple, and they can be set one-to-one. This is beneficial to improving the connection strength between the push block 32 and the slider unit 31.

[0045] In one embodiment, such as Figure 1 As shown, a pushing surface 3211 is provided on the side of the main body 321 near the push-out end 104. The pushing surface 3211 is perpendicular to the moving direction of the push block 32 to better cooperate with the goods and ensure the smooth push-out of the goods.

[0046] In another embodiment, such as Figure 1 As shown, a guide surface 3212 is provided on the side of the main body 321 away from the push-out end 104. The guide surface 3212 can be configured as an arc surface, curved surface, or inclined surface to match the shape of the outer frame of the goods edge, so as to prevent the goods from getting stuck on one side when the push block 32 slides back, thus avoiding obstruction. That is, when the push block 32 returns to the initial position from the push-out state, the guide surface 3212 can be used to guide it, making the push block 32 lift the goods more smoothly and preventing the goods from hindering the movement and reset of the push block 32.

[0047] When the push plate moves back to its initial position, in order to control the screw 21 to stop rotating in time and prevent the push block 32 from moving further, thereby improving the safety of the entire structure, in one embodiment, such as Figure 3 and Figure 4 As shown, the pusher block 32 also includes a trigger plate 324, one end of which is connected to the main body 321, and the other end extends at least partially into the receiving cavity 101. The dispensing mechanism 100 also includes a trigger switch 40, which is installed in the receiving cavity 101 and disposed away from the push-out end 104. The trigger switch 40 can be triggered by the trigger plate 324 to generate a feedback signal. That is, the position of the trigger plate 324 corresponds to the position of the pusher plate in the initial state. Thus, when the pusher plate moves to the initial state position, the trigger plate 324 on the pusher plate can cooperate with the trigger switch 40 to generate a feedback signal, thereby smoothly feeding back the movement state of the pusher block 32, so as to stop the rotation of the screw 21 and improve safety.

[0048] Specifically, the trigger switch 40 can be configured as a micro switch, photoelectric switch, or Hall switch, as long as it can cooperate with the trigger board 324 to achieve the same function.

[0049] In one embodiment, such as Figure 3 and Figure 4 As shown, the drive assembly 20 also includes a drive motor 22 and a first gear 23. The output shaft of the drive motor 22 is connected to the first gear 23 to drive the first gear 23 to rotate. The screw 21 includes a second gear 211 located at one end of the screw 21. The second gear 211 meshes with the first gear 23, enabling the drive assembly 20 to drive the screw 21 to rotate. Thus, through the meshing of the first gear 23 and the second gear 211, the torque of the drive motor 22 can be smoothly transmitted to the screw 21, thereby driving the screw 21 to rotate. Similarly, the gear can also be other transmission connecting parts that realize transmission, such as a turntable or a shaft.

[0050] Here, the drive motor 22 serves as the power source for the entire mechanism and can be fixed within the receiving cavity 101 via a snap-fit. Furthermore, the output shaft of the drive motor 22 is connected to the first gear 23 via a hole-shaft fit. The hole on the first gear 23 can be a flat hole or have at least one flat surface within it to achieve an anti-rotation effect with the output shaft of the drive motor 22, thus transmitting power. In addition, an interference fit is used between the hole and the shaft to improve the reliability of the connection. Furthermore, the drive motor 22 can also directly drive the screw 21 to move.

[0051] Furthermore, in this embodiment, the second gear 211 is integrally formed with the screw 21, thereby improving the overall structural strength. Of course, in other embodiments, they can also be separately configured and fixedly connected to ensure the driving reliability of the drive motor 22.

[0052] In one embodiment, the first gear 23 is configured as a self-lubricating wear-resistant plastic part, which helps to improve the wear resistance of the first gear 23 and reduce the wear caused by contact friction, thereby extending its service life.

[0053] In one embodiment, the screw 21 is configured as a self-lubricating wear-resistant plastic part, which helps to improve the wear resistance of the screw 21 and the second gear 211 and reduce the wear caused by contact friction, thereby extending the service life.

[0054] In one embodiment, the slider unit 31 is configured as a self-lubricating wear-resistant plastic part, which helps to improve the wear resistance of the slider unit 31 and reduce the wear caused by contact friction, thereby extending its service life.

[0055] In one embodiment, the push block 32 is configured as a self-lubricating wear-resistant plastic part, which helps to improve the wear resistance of the push block 32 and reduce the wear caused by contact friction, thereby extending its service life.

[0056] In one embodiment, such as Figure 3 and Figure 6 As shown, the slider unit 31 includes a slider body 311 and a transmission pin 312. The slider body 311 has a first mounting hole 3101 and a second mounting hole 3102 that are interconnected. The screw 21 passes through the first mounting hole 3101, and the transmission pin 312 is limited and installed in the second mounting hole 3102. One end of the transmission pin 312 is inserted into the double helical groove 2101 for transmission connection with the screw 21. It can be understood that the transmission pin 312 can make a certain angle of rotation within the second mounting hole 3102, thereby facilitating the engagement between the transmission pin 312 and the double helical groove 2101 on the screw 21 and ensuring the smooth movement of the slider unit 31 along the screw 21.

[0057] Specifically, the slider body 311 includes a support portion 3111 and a latching portion 3112. The latching portion 3112 connects to the support portion 3111 and forms a second mounting hole 3102 with the support portion 3111. The end of the latching portion 3112 away from the support portion 3111 is engaged with the end face of the transmission pin 312. Thus, by abutting the end of the transmission pin 312 with the latching portion 3112, the transmission pin 312 is prevented from detaching from the opening of the second mounting hole 3102, thereby improving the installation reliability of the transmission pin 312. The latching portion 3112 has a certain degree of elasticity, allowing the end of the latching portion 3112 away from the support portion 3111 to deform outwards, facilitating the insertion of the transmission pin 312 into the second mounting hole 3102.

[0058] To prevent the transmission pin 312 from disengaging from the slider body 311 in the event of a failure of the latching part 3112, in one embodiment, such as Figure 3 , Figure 4 and Figure 7 As shown, the slider unit 31 also includes a limiting member 313, which blocks the opening of the second mounting hole 3102 and is connected to the slider body 311. The limiting member 313 has a third mounting hole 3103, and the end of the connecting part 322 away from the main body 321 is inserted into the third mounting hole 3103 and connected to the limiting member 313. Thus, by using the limiting member 313 to auxiliary limit the transmission pin 312, the reliability of the transmission pin 312 installation is further improved, and at the same time, the connection with the push block 32 is achieved.

[0059] Specifically, when the connecting part 322 is inserted into the third assembly hole 3103, the limiting part 313 and the connecting part 322 can be connected in sequence by fasteners such as bolts, so as to ensure the stability of the push block 32 when it moves.

[0060] Furthermore, in one embodiment, as Figure 6 and Figure 7 As shown, the transmission pin 312 has a fourth mounting hole 3104, and the limiting member 313 protrudes to form a limiting protrusion 3131. The limiting protrusion 3131 is inserted into the fourth mounting hole 3104 and is connected to the transmission pin 312 for limiting. In this way, the limiting effect of the limiting member 313 on the transmission pin 312 is further improved, preventing the limiting pin from deviating from the preset position when the buckle part 3112 fails.

[0061] In one embodiment, such as Figure 3 As shown, the bracket 10 includes an upper cover 11 and a lower cover 12, which are connected by snap-fit ​​to form a receiving cavity 101, thereby reducing the difficulty of installing the various components within the receiving cavity 101. The upper cover 11 can also be configured as a self-lubricating, wear-resistant plastic part, which helps improve the wear resistance of the upper cover 11, reduces friction between the goods and the upper cover 11, reduces wear caused by contact friction, and thus extends its service life.

[0062] like Figure 8 As shown, this application also provides a vending machine, which includes the aforementioned dispensing mechanism 100. The vending machine also includes a storage compartment 200 and a housing 300. The storage compartment 200 is installed inside the housing 300 and is located above the dispensing mechanism 100. In this way, goods such as tissues in the storage compartment 200 can reach the support 10 of the dispensing mechanism 100 under the action of gravity or other forces, and be pushed out by the pusher block 32 to realize the sale.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
