[0043] Before introducing the ejection mechanism of the embodiment of the present application, its application scenario is first explained. The ejection mechanism of the present application can be used in automatic vending equipment, mainly to push the goods placed on the circulating shelves in the automatic vending equipment from the circulating shelves to the outside of the equipment. In order to make the best use of the space in the automatic vending equipment to place more circulating shelves and goods, the lateral space of the ejection mechanism (especially the front and rear directions for pushing the goods out) should not be too large.

[0044] Figure 1 is a structural schematic diagram of a push-out mechanism of a telescopic assembly in a retracted state according to an embodiment of the present application; Figure 2 is a schematic cross-sectional structural diagram of a push-out mechanism of a telescopic assembly in a retracted state according to an embodiment of the present application; Figure 3 is a structural schematic diagram of a push-out mechanism of a telescopic assembly in an extended state according to an embodiment of the present application; Figure 4 Schematic diagram of the cross-sectional structure of the push-out mechanism of the telescopic assembly in the extended state according to the embodiment of the present application. Figure 1-Figure 4 As shown, the ejection mechanism provided in the embodiment of the present application may include a storage bin body 100 , a fixed shell 200 , a telescopic assembly 300 , a flexible strip 400 and a driving member 500 .

[0045] The storage bin body 100 extends in a vertical direction, and a side wall has an opening; the fixed shell 200 is disposed at the opening of the storage bin body 100; the telescopic assembly 300 is sleeved with the fixed shell 200, and the telescopic assembly 300 moves relative to the fixed shell 200; the first end of the flexible strip 400 is disposed in the storage bin body 100, and the second end passes through the opening and is connected to the telescopic assembly 300 after turning at the opening; the driving member 500 is disposed in the storage bin body 100 and is connected to the flexible strip 400, and the driving member 500 is configured to drive the flexible strip 400 to move, so that the flexible strip 400 pushes the telescopic assembly 300 to move in a direction away from or close to the fixed shell 200.

[0046] It is understandable that the storage bin body 100 can be configured to be in a long strip shape, and the long strip storage bin body 100 extends in the vertical direction. The storage bin body 100 is mainly used to store the flexible strip 400, and to ensure that the flexible strip 400 is stored in the storage bin body 100, one end of the flexible strip 400 can be movably arranged in the storage bin body 100. In addition, to ensure the maximum storage space of the storage bin body 100, the opening of the side wall thereof can be opened at the top side or the bottom side of the storage bin body 100. Exemplarily, the opening is opened at the side wall at the bottom of the storage bin body 100.

[0047] In order to realize the lateral movement of the ejection mechanism, a fixed housing 200 is installed at the opening of the side wall of the storage bin body 100, and the fixed housing 200 is sleeved with a telescopic assembly 300, and the telescopic assembly 300 can move relative to the fixed housing 200, and the moving direction of the telescopic assembly 300 is a non-vertical direction. Exemplarily, the moving direction of the telescopic assembly 300 is a horizontal direction, of course, it can also be a direction above or below the horizontal direction, which is not limited here.

[0048] The telescopic component 300 and the fixed casing 200 can be mounted in a way that the telescopic component 300 is small and mounted inside the fixed casing 200, or the telescopic component 300 is large and mounted outside the fixed casing 200. The specific mounting method is not limited here.

[0049] In order to realize the movement of the telescopic component 300 relative to the fixed shell 200, the second end of the flexible strip 400 is connected to the telescopic component 300. Since the extension direction of the storage bin body 100 is different from the telescopic direction of the telescopic component 300, the second end of the flexible strip 400 needs to be turned at the exit position (for example, from the vertical direction to the horizontal direction) to facilitate entering the telescopic component 300 and connecting with the telescopic component 300.

[0050] It should be noted that the second end of the flexible strip 400 can be connected to the inner end face of the telescopic assembly 300, or connected to the outer end face of the telescopic assembly 300. The outer end face of the telescopic assembly 300 is the end face away from the storage bin body 100, and the end face can be provided with a push plate 320, which is convenient for connecting the second end of the flexible strip 400 with the push plate 320 on the one hand, and is convenient for pushing the goods to move on the other hand.

[0051] In one example, the flexible strip 400 can be a chain, and the driving member 500 can be correspondingly configured as a driving gear, which meshes with the chain. The rotation of the driving gear can drive the chain to move, and the movement of the chain can push the telescopic assembly 300 to move away from the fixed housing 200 to push the goods to move. Of course, the movement of the chain can also push the telescopic assembly 300 to move toward the fixed housing, so that the goods can move to the push-out mechanism along with the circulating shelf (carrier, etc.), so as to facilitate the next push-out of the goods.

[0052] In addition, to avoid serious deformation of ordinary chains during the pushing process or the process of shrinking to the storage bin body 100. In some examples, the flexible strip 400 is a guide bending chain. Since the guide bending chain has excellent impact resistance, it can maintain a stable center of circle when subjected to sudden load changes or external force impacts, and is not prone to breakage or serious deformation. In addition, the guide bending chain can operate in a wide temperature range from extremely low temperature to high temperature, ensuring the possibility of application under various environmental conditions (such as vending machines including freezers). The setting of the guide bending chain effectively ensures the possibility of pushing or pulling the telescopic assembly 300 relative to the fixed sleeve 200 under the drive of the drive member 500.

[0053] It should be noted that in order to further ensure that the flexible strip 400 drives the telescopic assembly 300 to move under the drive of the driving member 500, an arc guide groove or an arc channel can be set in a section from the opening of the storage bin body 100 to the fixed shell 200 to provide support for the turning of the flexible strip 400, avoid or slow down its deformation, thereby improving the movement efficiency of the flexible strip 400 to push the telescopic assembly 300.

[0054] In the present application, a fixed shell 200 and a telescopic assembly 300 are set whose telescopic directions are different from the extension direction of the storage bin body 100, and the second end of the flexible strip 400 stored in the storage bin body 100 is connected to the outer end surface of the telescopic assembly 300 after turning at the opening, and the flexible strip 400 is driven to move by the driving member 500, thereby indirectly driving the telescopic assembly 300 to move away from or close to the fixed shell 200. This arrangement can not only smoothly push out the goods, but also effectively reduce the space occupied by the propulsion mechanism in the lateral direction.

[0055] Next, we will combine the attached Figure 1 -Attached Figure 5 The detailed structure of the ejection mechanism provided in the embodiment of the present application is introduced.

[0056] like Figure 2 and Figure 4 As shown, in some embodiments, the telescopic assembly 300 includes a plurality of telescopic covers 310 , which are sleeved in sequence. The plurality of telescopic covers 310 are extended or contracted in sequence driven by the flexible strip 400 .

[0057] It can be understood that in order to increase the length that the ejection mechanism can eject, the telescopic assembly 300 can include a multi-section telescopic shell 310, and the multiple telescopic shells 310 are sequentially socketed. For example, the multi-section telescopic shell 310 can be socketed inside the fixed shell 200, then the telescopic shell 310 connected to the flexible strip 400 is the innermost telescopic shell 310; it can also be socketed on the outside of the fixed shell 200, then the telescopic shell 310 connected to the second end of the flexible strip 400 is the outermost telescopic shell 310, and the socketing method of the multi-section telescopic shell 310 and the fixed shell 200 is not limited here.

[0058] like Figure 3 and Figure 4 As shown, in some embodiments, when the multi-section telescopic shell 310 is in the expanded state, the telescopic shell 310 farthest away from the fixed shell 200 is the first telescopic shell 311, and the end surface of the first telescopic shell 311 away from the fixed shell 200 is connected to the second end of the flexible strip 400.

[0059] Specifically, in order to clearly mark the connection between the second end of the flexible strip 400 and the flexible sleeve, when the multi-section telescopic sleeve 310 is in the expanded state, the telescopic sleeve 310 facing away from the farthest end of the fixed sleeve 200 is defined as the first telescopic sleeve 311, and the end surface of the first telescopic sleeve 311 away from the fixed sleeve 200 is provided with a push plate 320, and the push plate 320 is connected to the second end of the flexible strip 400.

[0060] The movement process of the multi-section telescopic cover 310 is as follows: when the multi-section telescopic cover 310 needs to be extended, the flexible strip 400 gradually extends out from the storage bin body 100 under the drive of the driving member 500, and continues to move in the extension direction of the telescopic assembly 300 after turning at the opening. At this time, the first telescopic cover 311 extends in the direction away from the fixed cover 200 under the drive of the flexible strip 400 until it reaches its limit, and then drives the second section of the telescopic cover 310 connected to the first telescopic cover 311 to move until the last section of the telescopic cover 310 is extended (the actual movement distance of the flexible strip 400 needs to be set according to the specific push-out).

[0061] Similarly, when the multi-section telescopic cover 310 needs to be contracted, the flexible strip 400 gradually moves into the storage bin body 100 under the drive of the driving member 500. At this time, the flexible strip 400 drives the first telescopic cover 311 to move toward the direction close to the fixed cover 200, and successively brings the second section and the last section of the telescopic cover 310 back to the fixed cover 200, completing the contraction of the multi-section telescopic cover 310.

[0062] like Figure 2 and Figure 4 As shown, in some embodiments, an elastic member 600 is connected between the flexible strip 400 and the first telescopic housing 311 .

[0063] It can be understood that during the contraction process of the multi-section telescopic sleeve 310, especially when the first telescopic sleeve 311 retracts to the fixed sleeve 200, a stop signal will be sent to the driving member 500, and the driving member 500 (the motor 510 described below) will stop after receiving the stop signal. Due to the hysteresis of the braking of the driving member 500, the first telescopic sleeve 311 will continue to be driven to move in the direction of the storage bin body 100. In order to avoid damage to the telescopic assembly 300, an elastic member 600, such as a tension spring, is arranged between the flexible member and the push plate 320 of the first telescopic sleeve 311, so as to play a buffering role when the driving member 500 is continuously driven, thereby avoiding or alleviating the situation where the flexible member is pulled too tight when the driving member 500 drives the first telescopic sleeve 311 to descend, so as to increase the service life of the telescopic assembly 300.

[0064] like Figure 2 and Figure 4 As shown, in some embodiments, the first end of the flexible strip 400 is disposed on the side wall of the storage bin body 100 through the rotating shaft 110 .

[0065] Specifically, the first end of the flexible strip 400 is rotatably arranged on the side wall of the storage bin body 100 through the rotating shaft 110. On the one hand, it can prevent the driving member 500 from driving all the flexible strips 400 outside the storage bin body 100, resulting in the flexible strips 400 not being able to be stored back; on the other hand, during the process of the flexible strip 400 moving outward from the storage bin body 100, the first end of the flexible strip 400 can be rotated according to the moving trend of the flexible strip 400 to prevent the flexible strip 400 from being stuck in the storage bin body 100. This arrangement can improve the smoothness of the flexible strip 400 moving from the storage bin body 100, thereby improving the pushing efficiency of the pushing mechanism.

[0066] like Figure 1 and Figure 3 As shown, in some embodiments, the driving member 500 may include a motor 510 and a driving wheel 520. The motor 510 is disposed on the inner wall of the storage bin body 100; the driving wheel 520 is connected to the output shaft of the motor 510, and the driving wheel 520 is engaged with the guide bending chain, so that the guide bending chain drives at least one of the multi-section telescopic casings 310 to move under the drive of the motor 510.

[0067] Specifically, the driving wheel 520 is a driving gear that can engage with the above-mentioned guide bending chain. Under the drive of the motor 510, the driving wheel 520 rotates, thereby driving the guide bending chain to move out of or be stored in the storage bin body 100.

[0068] It should be noted that in this embodiment, two or more sets of storage bins 100, fixed shells 200, telescopic components 300, flexible strips 400 and driving wheels 520 with the same structure can be set in the same device, so that the goods can be pushed together by two or more first telescopic shells 311 to improve the stability during the pushing process. Of course, the two sets of pushing mechanisms can share a motor 510 to achieve synchronization of the pushing of the two telescopic shells 310.

[0069] In some embodiments, a limiter (not shown) is disposed at the connecting end of any two adjacent telescopic sleeves 310 to limit the extension and contraction of the telescopic sleeves 310 .

[0070] It is understandable that, in order to ensure the effective extension or contraction of any two adjacent telescopic shells 310, a limiter is provided at the connecting end of the telescopic shell 310, and the limiter can be a protrusion provided on the side wall of the multiple telescopic shells 310 facing the fixed shell 200, and the side wall of the multiple telescopic shells 310 is configured with a guide groove adapted to the protrusion, and the guide groove has a limit at the end of the multiple telescopic shells 310 away from the fixed shell 200 to prevent the protrusion from sliding out of the guide groove. The specific limit between the multiple telescopic shells 310 is not limited.

[0071] like Figure 3 As shown, in some embodiments, a first sensing element 210 is disposed at the fixed shell 200 , and a first sensing sheet 321 is disposed on the outer end surface of the first telescopic shell 311 . The first sensing sheet 321 is configured to trigger the first sensing element 210 when the first telescopic shell 311 is retracted to the fixed shell 200 .

[0072] It is understandable that when the multi-section telescopic shell 310 is retracted to the fixed shell 200, in order to stop the driving member 500 from continuing to drive the flexible strip 400 to move, a stop signal needs to be sent to the motor 510 in the driving member 500 in time. Based on this, in this example, a first sensing member 210 can be set at the end of the fixed shell 200 away from the storage bin body 100, and a first sensing sheet 321 can be set at the push plate 320 of the first telescopic shell 311. When the first sensing member 210 approaches the first sensing member 210 to a preset distance, the first sensing member 210 will be triggered, so that the first sensing member 210 sends a stop signal to the motor 510.

[0073] It should be noted that the first sensing sheet 321 may be a magnet, and the first sensing element 210 may be a reed sensor or a magnetic proximity sensor. Of course, the first sensing sheet 321 may also be a baffle with good reflective performance, and the first sensing element 210 may be an infrared sensor. The specific configuration of the first sensing sheet 321 and the corresponding first sensing element 210 is not limited here.

[0074] like Figure 5As shown, in some embodiments, a second sensor 120 is provided on the side wall of the storage bin body 100, and a second sensor sheet is provided on a preset section of the flexible strip 400, and the second sensor sheet is configured to trigger the second sensor 120 when the first telescopic sleeve 311 is extended to a predetermined position.

[0075] It can be understood that in order to sense whether the first telescopic sleeve 311 is extended into place, a second sensing sheet can be set at a certain section of the flexible strip 400, and a second sensing element 120 can be set at a certain place on the side wall of the storage bin body 100. The second sensing sheet can be used to trigger the second sensing element 120 to realize that the first telescopic sleeve 311 is extended into place and the motor 510 stops moving or the motor 510 rotates in the opposite direction.

[0076] It should be noted that the sensing methods of the second sensing element 120 and the second sensing sheet can be set with reference to the first sensing element 210 and the first sensing sheet 321 , which will not be described in detail herein.

[0077] Of course, in addition to the above-mentioned configuration of the sensing element and the sensing sheet, an absolute encoder may also be provided on the rotating shaft 110 side of the driving wheel 520 to calculate the moving distance of the flexible strip 400 by the rotation of the driving wheel 520, and further calculate whether the first telescopic sleeve 311 is retracted or extended into place.

[0078] like Figure 4 As shown, in some embodiments, a guide wheel 330 is provided at the end of the first telescopic cover 311 away from the fixed cover 200, and an avoidance groove 340 adapted to the guide wheel 330 is opened at the end of the other telescopic cover 310 away from the storage bin body 100; the guide wheel 330 is protruding from the bottom of the first telescopic cover 311.

[0079] It is understandable that the guide wheel 330 can also roll along the telescopic direction of the first telescopic cover 311. Combined with the setting that the guide wheel 330 protrudes from the bottom of the first telescopic cover 311, when the first telescopic cover 311 enters the circulation shelf, the guide wheel 330 can contact the bottom of the circulation shelf to support the first telescopic cover 311 and the remaining telescopic covers 310, thereby improving the smoothness of the telescopic assembly 300 pushing the goods and reducing the driving pressure of the driving member 500. The setting of the avoidance groove 340 on the remaining telescopic covers 310 can facilitate the first telescopic cover 311 to be set in the remaining telescopic covers 310.

[0080] In addition, in this example, each telescopic sleeve can be adaptively hollowed out to reduce the weight of the telescopic sleeve as much as possible, thereby further reducing the driving pressure of the driving member 500.

[0081] The embodiment of the present application also provides an unmanned vending machine, including a cabinet, a window opened on a side wall of the cabinet, a circulating shelf, and a push-out mechanism of the above embodiment, which is arranged in the cabinet and is used to push the goods on the circulating shelf out of the window. The internal structure of the specific unmanned vending machine can be modified with reference to the prior art, and the setting of the push-out mechanism can greatly release the lateral space between the circulating shelves, so that after the circulating shelves are reasonably set, the overall size of the unmanned vending machine can be reduced.

[0082] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
