DETAILED DESCRIPTION

[0034] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0035] As a specific embodiment, the automatic pickup cabinet structure of the embodiment of the utility model includes a cargo output device 91, a driving assembly 2, a linkage rod 3, and a pickup cabinet assembly 1 located below the cargo output device 91. The cargo output device 91 is a device for outputting cargo of a conventional vending machine 9, such as a spiral track output device, a push plate output device, etc.

[0036] The pickup cabinet assembly 1 includes a cabinet body 11, an outer cabinet door 12, and an inner cabinet door 13. The cabinet body 11, the outer cabinet door 12, and the inner cabinet door 13 are enclosed to form an inner cavity of the pickup cabinet assembly 1 with an open top. The goods output by the goods output device 91, such as bottled water, bagged snacks, etc., can fall into the inner cavity of the pickup cabinet assembly 1 from the top opening of the pickup cabinet assembly 1.

[0037] The outer cabinet door 12 is located outside the cabinet body 11 and is provided with an outer cabinet door hinge part 122 hinged to the cabinet body 11, so that the outer cabinet door 12 can rotate around the axis of the outer cabinet door hinge part 122. The inner cabinet door 13 is located inside the cabinet body 11 and is provided with an inner cabinet door hinge part 132 hinged to the cabinet body 11, so that the inner cabinet door 13 can rotate around the axis of the inner cabinet door hinge part 132.

[0038] The outer cabinet door 12 is provided with a linkage ear 121, the inner cabinet door 13 is provided with a linkage hinge 133, and the two ends of the linkage rod 3 are respectively hinged to the linkage ear 121 and the linkage hinge 133. It is easy to understand that there must be a distance between the linkage ear 121 and the outer cabinet door hinge 122, and there must be a distance between the linkage hinge 133 and the inner cabinet door hinge 132.

[0039] The driving assembly 2 includes a power gear 21, a driving gear 22, and a driving frame 29 fixed relative to the cabinet 11, for example, the driving frame 29 is fixedly connected to the cabinet 11 or the vending machine 9; the power gear 21 and the driving gear 22 are both hinged to the driving frame 29. The power gear 21 has a rotational power.

[0040] The driving gear 22 includes a driving abutment 221, a driving gear starting line 223 and a driving gear end line 224. Between the driving gear starting line 223 and the driving gear end line 224 is a driving gear portion 222 that can mesh with the power gear 21. Fig.12 As shown, the driving tooth portion 222 is a sector-shaped rack as a whole, and its corresponding central angle is the driving tooth central angle 225, and the two sides of the driving tooth central angle 225 are respectively the driving tooth starting line 223 and the driving tooth end line 224. When the driving tooth portion 222 is meshed with the power gear 21, the power gear 21 can drive the driving tooth 22 to rotate, but in the portion other than the area before the driving tooth end line 224 and the driving tooth starting line 223 (i.e., the driving tooth central angle 225), the power gear 21 and the driving tooth portion 222 are not meshed.

[0041] The inner cabinet door 13 is provided with a resisted body 131 facing away from the outer cabinet door 12, and the driving resisting body 221 is against or close to the resisted body 131 and has a tendency to approach the resisted body 131. It is easy to understand that the inner cabinet door 13 is located between the outer cabinet door 12 and the resisted body 131 so that the resisted body 131 faces away from the outer cabinet door 12. The tendency of the driving resisting body 221 to approach the resisted body 131 can be generated by setting the center of gravity of the driving gear 22, or by conventional means such as springs and magnetic attraction.

[0042] When the outer cabinet door 12 is in the closed state, the power gear 21 is located outside the driving tooth starting point line 223. Fig.12 As shown, when the outer cabinet door 12 is substantially vertical and the inner cavity of the pickup cabinet assembly 1 is completely separated from the outer cavity by the outer cabinet door 12, there is no path that can connect from the outer cavity of the pickup cabinet assembly 1 to the inner cavity of the pickup cabinet assembly 1; at this time, the outer cabinet door 12 is in a closed state. At this time, the power gear 21 is located outside the starting line 223 of the driving teeth and is not meshed with the driving tooth portion 222.

[0043] The working principle is as follows: Fig.10As shown, when a customer purchases goods, the goods output device 91 of the vending machine 9 outputs the goods to the inner cavity of the pickup cabinet assembly 1, and the goods fall on the cabinet bottom wall 119 of the cabinet body 11. The motor 219 is started, and the power gear 21 drives the driving gear 22 to rotate forward until the power gear 21 is closest to the driving tooth end line 224, so that the driving abutting body 221 abuts against the abutted body 131 to rotate the inner cabinet door 13, and at the same time, the linkage rod 3 moves toward the driving gear 22 to rotate the outer cabinet door 12 into the inner cavity of the pickup cabinet assembly 1, so that the inner cavity of the pickup cabinet assembly 1 is connected with the outer side thereof, and at this time, the customer can take out the goods from the outer side of the pickup cabinet assembly 1. Usually, in the process of the power gear 21 driving the driving gear 22 to rotate forward, the power gear 21 will not cross the driving tooth end line 224 relative to the driving gear 22 and maintain meshing with the driving tooth portion 222. Of course, the power gear 21 can also cross the driving tooth end line 224 relative to the driving gear 22. When the power gear 21 drives the driving gear 22 to rotate forward and opens the outer cabinet door 12, the gap between the outer cabinet door 12 and the cabinet body 11 gradually increases without pinching the hand of a person extending into the inner cavity of the pickup cabinet assembly 1.

[0044] When the customer takes out the goods from the outside of the pickup cabinet assembly 1, the motor 219 is started, and the power gear 21 drives the driving gear 22 to rotate in the opposite direction until the power gear 21 passes over the driving gear starting line 223, and is located outside the driving gear starting line 223; in this process, the outer cabinet door 12 is reset to a closed state due to its own weight, and the inner cabinet door 13 is also reset due to the driving of the outer cabinet door 12 and the linkage rod 3. In the process that the power gear 21 drives the driving gear 22 to rotate in the opposite direction and resets the outer cabinet door 12 to a closed state, the driving abutting body 221 abuts against the abutted body 131 to limit the rotation and closing speed of the outer cabinet door 12, which can prevent the outer cabinet door 12 from closing quickly and pinching the hand of a person who extends into the inner cavity of the pickup cabinet assembly 1. When the outer cabinet door 12 is close to a closed state, the power gear 21 reaches the driving tooth starting line 223 relative to the driving tooth member 22. At this time, the power gear 21 continues to rotate and the driving tooth member 22 will cause the driving tooth member 22 to jump, causing the inner cabinet door 13 and the outer cabinet door 12 to also jump, thereby reminding and preventing the hands of people who extend into the inner cavity of the pickup cabinet assembly 1 from being pinched. Even if the angle sensor 23 described later fails, it can prevent the hands of people who extend into the inner cavity of the pickup cabinet assembly 1 from being pinched.

[0045] When the hand is taken out from the inner cavity of the take-out cabinet assembly 1, the power gear 21 is located outside the starting line 223 of the driving tooth. However, the driving abutting body 221 has a tendency to approach the abutted body 131, so when the outer cabinet door 12 is opened next time, the power gear 21 can still reliably drive the driving gear 22 to rotate in the positive direction (see Fig.10 , 11 The state of the power gear 21 and the driving tooth portion 222 shown in the figure, both of which have only one tooth partially in contact with each other), can improve reliability.

[0046] It can be seen from the above that in the automatic pickup cabinet structure of the embodiment of the utility model, while the outer cabinet door 12 rotates inward to open, the rotation speed of the outer cabinet door 12 is limited when it rotates closed, which can remind and prevent the hand reaching into the inner cavity of the pickup cabinet assembly 1 from being pinched, and has higher safety.

[0047] As one of the specific implementations, the cabinet body 11 includes a cabinet side wall 111; the cabinet side wall 111 is provided with a through slot 112, the linkage ear 121 is located on the inner side of the cabinet side wall 111, and the linkage rod 3 is located on the outer side of the cabinet side wall 111 and directly opposite to the through slot 112. It is easy to understand that the hinged rod between the linkage ear 121 and the linkage rod 3 passes through the through slot 112. While ensuring that the side wall of the outer cabinet door 12 fits the inner wall of the cabinet side wall 111 and ensures sealing, the movable linkage rod 3 is located on the outer side of the inner cavity of the pickup cabinet assembly 1, and it will not contact with human hands, etc., thereby improving safety.

[0048] As one of the specific implementations, both ends of the inner cabinet door 13 are provided with inner cabinet door connecting ears 134, which are respectively located on the outer sides of the cabinet side walls 111, and the linkage hinge part 133 and the inner cabinet door hinge part 132 are both arranged on the inner cabinet door connecting ears 134. During assembly, the hinge column and other parts used for hinge connection and the linkage rod 3 can be installed on the outer side of the cabinet side wall 111, which is convenient for assembling the cargo cabinet assembly 1.

[0049] As one of the specific implementations, when the outer cabinet door 12 is in a closed state, the linkage hinge portion 133 is located above the inner cabinet door hinge portion 132. This ensures that the linkage rod 3 moves smoothly without getting stuck.

[0050] As one of the specific implementations, the outer cabinet door 12 includes a counterweight 123; the counterweight 123 is located outside the outer cabinet door hinge 122. Fig.12 As shown, the counterweight 123 is located on the left side of the vertical plane passing through the axis of the outer cabinet door hinge 122, so that the counterweight 123 is located outside the outer cabinet door hinge 122. The overall center of gravity of the outer cabinet door 12 is located outside the outer cabinet door hinge 122, so that the outer cabinet door 12 has a tendency to rotate closed, which can ensure that the outer cabinet door 12 is closed.

[0051] As one of the specific implementations, the driving abutting body 221 is hinged with an abutting roller 229 and abuts or approaches the abutted body 131 through the abutting roller 229. The friction generated when the driving abutting body 221 directly abuts against the abutted body 131 can be eliminated, thereby ensuring that the inner cabinet door 13 and the outer cabinet door 12 can be opened smoothly.

[0052] As one of the specific embodiments, the inner cabinet door 13 is provided with an extension body 139, and when the outer cabinet door 12 is opened, the abutting body 131 and the outer cabinet door 12 overlap in the horizontal direction. Fig.12 Under the premise that the distance from the bottom wall 119 to the lower end of the outer cabinet door 12 is large enough to accommodate larger goods, when the outer cabinet door 12 is opened, the top opening of the inner cavity of the cargo collection cabinet assembly 1 is blocked by the supporting body 131 and the outer cabinet door 12, thereby preventing theft.

[0053] As one of the specific implementations, the outer cabinet door 12 is provided with a fitting body 124, and when the outer cabinet door 12 is opened, the abutted body 131 contacts the fitting body 124, which can further improve the anti-theft performance.

[0054] As one of the specific implementations, a motor 219 is fixedly arranged on the driving frame 29, and the rotation output end of the motor 219 is fixedly connected to the power gear 21 so that the power gear 21 has a rotational power. The driving assembly 2 also includes a rotation angle sensor 23 that is electrically connected to the motor 219 and fixed on the driving frame 29, and the driving gear 22 can trigger the rotation angle sensor 23 to control the motor 219. The rotation angle sensor 23 is a mechanical micro switch, etc., which can limit the rotation angle of the driving gear 22 and the outer cabinet door 12 to further improve safety.

[0055] As one of the specific implementations, the rotation angle sensor 23 includes an outer door closing sensor 231 that is triggered when the outer door 12 is closed, and / or an outer door opening sensor 232 that is triggered when the outer door 12 is opened. The rotation angle of the driving gear 22 and the outer door 12 can be limited to further improve safety.

[0056] As one of the specific implementations, a trigger wheel 226 is disposed inside the driving gear 22 , and the trigger wheel 226 can trigger the outer cabinet door opening sensor 232 when the outer cabinet door 12 is opened, which is beneficial to the miniaturization of the driving assembly 2 .

[0057] As one of the specific implementations, the driving frame 29 is provided with a protective cover 299; the protective cover 299 shields the driving gear portion 222 and the power gear 21, so as to improve the safety when the driving assembly 2 is accessible during installation and maintenance.

[0058] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0059] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0060] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0061] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the relevant standards of dimensional tolerance.
