[0040] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present embodiment provides a pickup door installation structure, which can be used to install the pickup door of a vending machine, so that users can pick up goods after purchasing items. Specifically, the vending machine can be an automatic coffee vending machine. After the coffee is made, the pickup door automatically opens and the user takes the coffee.

[0044] like Figure 1 As shown, the pickup door installation structure includes a guide component 1 and a limit component 2. The pickup door 100 is slidably arranged on the inner side of the panel 200 of the vending machine through the guide component 1 to close or open the pickup port of the vending machine. The pickup door 100 adopts a sliding motion form, has a simple structure, does not need to reserve a door opening space, saves space, is easy to realize automation, and is convenient for users to take items. The action of opening and closing the pickup door 100 is completed inside, which improves the user's shopping experience and sense of security. When the pickup door 100 slides to a preset position, the limit component 2 can limit the pickup door 100 from moving toward the panel 200, so that the outer surface of the pickup door 100 is flush with the outer surface of the panel 200, the outer surface is flat and beautiful, and the airtightness is good, which prevents dirt from entering the interior of the vending machine through the gap of the pickup door 100, and improves the cleanliness of the interior of the vending machine.

[0045] like Figures 2 to 4As shown, optionally, the limiting assembly 2 includes a limiting post 21, and a limiting groove 101 is provided on the side of the pickup door 100. The limiting groove 101 is tilted, and the limiting post 21 can slide in the limiting groove 101 to drive the pickup door 100 to move toward the panel 200. Since the limiting groove 101 is tilted, the limiting post 21 can generate a thrust on the pickup door 100 through the cooperation between the limiting post 21 and the limiting groove 101, so that the pickup door 100 moves toward the panel 200. In this embodiment, the limiting groove 101 is bent, and when the limiting post 21 is located at the upper end (first position) of the limiting groove 101, it can provide an upward pulling force to the pickup door 100, and when the limiting post 21 is located at the lower end (second position) of the limiting groove 101, it can provide a downward thrust to the pickup door 100.

[0046] Optionally, an elastic member 22 is provided between the limiting column 21 and the pickup door 100, and the elastic member 22 is used to buffer the impact force of the pickup door 100 and / or overcome the gravity of the pickup door 100. In this embodiment, the guide assembly 1 is arranged in a vertical direction, and the pickup door 100 moves upward to close the pickup port. The elastic member 22 can be a tension spring, which can not only buffer the impact force of the pickup door 100, but also provide a pulling force to the pickup door 100 to overcome the gravity of the pickup door 100. The pickup door 100 is provided with a protrusion 104 for fixing the tension spring. In other embodiments, when the pickup door 100 moves downward to close the pickup port, the elastic member 22 can be a compression spring to buffer the impact force of the pickup door 100. If the pickup door 100 opens toward the sky (i.e., slides upward to complete the door opening action), the elastic member 22 can also be removed due to its own gravity.

[0047] like Figure 5 As shown, optionally, the limiting assembly 2 further includes a first limiting block 23, and a first roller 102 is provided on the cargo pickup door 100. When the cargo pickup door 100 slides to a preset position, the first roller 102 can contact the first limiting block 23 and roll on the first limiting block 23. The cargo pickup door 100 moves upward to a preset position, at which time the first roller 102 contacts the bottom of the first limiting block 23. Under the limiting action of the first limiting block 23, the cargo pickup door 100 changes from an upward motion to a motion toward the panel 200.

[0048] like Figure 6 As shown, optionally, the limiting assembly 2 further includes a second limiting block 24, and a second roller 103 is provided on the cargo pickup door 100. When the cargo pickup door 100 slides to a preset position, the second roller 103 can contact the second limiting block 24 and roll on the second limiting block 24. The first limiting block 23 and the second limiting block 24 are used to limit the upper and lower sides of the cargo pickup door 100 respectively, and the first roller 102 and the second roller 103 are conducive to reducing the resistance of the cargo pickup door 100 moving toward the panel 200.

[0049] like Figures 7 to 9 As shown, optionally, the rolling distance of the first roller 102 on the first limit block 23 is different from the rolling distance of the second roller 103 on the second limit block 24. When the pickup door 100 moves upward to close the pickup port, the length of the first limit block 23 is greater than the length of the second limit block 24, that is, the first roller 102 first contacts the first limit block 23, and then the first roller 102 rolls on the first limit block 23 for a distance before the second roller 103 contacts the second limit block 24 and rolls on it, that is, the rolling distance of the first roller 102 on the first limit block 23 is greater than the rolling distance of the second roller 103 on the second limit block 24. When the pickup door 100 moves downward to close the pickup port, the opposite is true. In this embodiment, rollers are provided at the four corners of the pickup door 100, the upper one is the first roller 102, and the lower one is the second roller 103. Correspondingly, limit blocks are provided at the four corners of the pickup port of the panel 200, the upper one is the first limit block 23, and the lower one is the second limit block 24.

[0050] like Figure 2 As shown, optionally, the guide assembly 1 includes a guide rail 11 and a slider 12, the guide rail 11 is arranged on the inner side of the panel 200, the slider 12 is slidably arranged on the guide rail 11, a connecting block 13 is arranged on the slider 12, and a limiting column 21 is fixed on the connecting block 13. In this embodiment, in order to facilitate the installation of the guide rail 11, a mounting plate 14 is fixedly connected to the panel 200, and the guide rail 11 is installed on the mounting plate 14. Two mounting plates 14 are provided, located on both sides of the pickup port. In this embodiment, four sliders 12 are provided, two guide rails 11 are provided, and the four sliders 12 are distributed on the two guide rails 11 in pairs, and four corresponding connecting blocks 13, limiting columns 21 and limiting grooves 101 are each provided, so as to improve the movement stability of the pickup door 100.

[0051] like Figure 2 and Figure 3 As shown, optionally, the pickup door installation structure further includes a driving component 3, two guide rails 11 are provided, the two guide rails 11 are located on both sides of the pickup port, each guide rail 11 is provided with at least one slider 12, and the driving component 3 is used to drive the sliders 12 on the two guide rails 11 to slide synchronously. The driving component 3 drives the sliders 12 on the two guide rails 11 to slide synchronously, which can ensure that both sides of the pickup door 100 are evenly stressed and the pickup port is tightly closed when it is closed.

[0052] Optionally, the drive assembly 3 includes a motor 31, a synchronous shaft 32, two gears 33 and two racks 34. The output end of the motor 31 is connected to the synchronous shaft 32. The synchronous shaft 32 can drive the two gears 33 to rotate synchronously. The two gears 33 are connected to the two racks 34 in a one-to-one correspondence. The two racks 34 are arranged in a one-to-one correspondence with the two guide rails 11. Through the cooperation of the gears 33 and the racks 34, it is convenient to improve the control accuracy of the sliding position of the pickup door 100. In addition, photoelectric switches are provided at the fully closed position and the fully open position of the pickup door 100 to facilitate the generation of signals to control the motor 31 to stop in time. Of course, in other embodiments, the slider 12 can also be driven to slide synchronously on the guide rail 11 through a conveyor belt structure.

[0053] The installation structure of the pickup door provided in this embodiment has the following working process when the pickup port is opened: Figure 7 As shown, the pickup door 100 is in a closed position, the motor 31 drives the synchronous shaft 32 to drive the gear 33 to rotate, and the rack 34 meshing with the gear 33 moves downward, driving the slider 12 thereon to slide downward on the guide rail 11, and the connecting block 13 fixedly connected to the slider 12 drives the limiting column 21 to slide in the limiting groove 101 of the pickup door 100. Since the limiting groove 101 is bent, during the process of the limiting column 21 sliding from the upper end to the lower end of the limiting groove 101, the limiting column 21 generates a thrust to the right (as shown in the figure) on the pickup door 100. Under the joint limiting action of the first roller 102 and the first limiting block 23, the second roller 103 and the second limiting block 24, the pickup door 100 moves away from the panel 200 to the right (as shown in the figure), as shown in FIG. Figure 8 As shown, when the second roller 103 is completely separated from the second limiting block 24, the limiting column 21 slides to the lower end of the limiting groove 101, and the limiting column 21 generates a downward thrust on the pickup door 100, as shown in FIG. Fig. 9 As shown, the first roller 102 is disengaged from the first limit block 23, and the pickup door 100 moves downward as a whole until the pickup opening is opened.

[0054] The cargo pickup door installation structure provided in the present embodiment has a working process exactly opposite to the working process of opening the cargo pickup door when closing the cargo pickup door, which is roughly as follows: the cargo pickup door 100 is in the open position, the motor 31 drives the synchronous shaft 32 to drive the gear 33 to rotate, and the rack 34 meshing with the gear 33 moves upward, driving the slider 12 thereon to slide upward on the guide rail 11, and the slider 12 drives the connecting block 13 and the limiting column 21 thereon to slide upward. Since the pulling force of the elastic member 22 is greater than the gravity of the cargo pickup door 100, under the pulling force of the elastic member 22, the limiting column 21 located at the lower end of the limiting groove 101 drives the elastic member 22 and the cargo pickup door 100 to move upward together. When the first roller 102 contacts the first limiting block 23, the limiting column 21 21 starts to slide upward in the limit groove 101. Since the limit groove 101 is bent, the limit column 21 generates a thrust to the left (as shown in the figure) on the pickup door 100 during the process of sliding from the lower end to the upper end of the limit groove 101. The first roller 102 rolls along the bottom surface of the first limit block 23, and the second roller 103 gradually contacts the second limit block 24 and rolls on it. Under the common limiting action of the first roller 102 and the first limit block 23, the second roller 103 and the second limit block 24, the pickup door 100 moves to the left (as shown in the figure) close to the panel 200. When the limit column 21 slides to the upper end of the limit groove 101, the outer surface of the pickup door 100 is flush with the outer surface of the panel 200, and the pickup port is tightly closed.

[0055] The pickup door installation structure provided in this embodiment adopts a sliding movement form for the pickup door 100, which has a simple structure and does not require reserved space for opening the door, thus saving occupied space and being easy to automate, making it convenient for users to take items. The action of opening and closing the pickup door 100 is completed internally, thereby improving the user's shopping experience and sense of security. The outer surface of the pickup door 100 is flush with the outer surface of the panel 200, and the outer surface is flat and beautiful with good airtightness, thereby preventing dirt from entering the interior of the vending machine through the gap in the pickup door 100, thereby improving the cleanliness of the interior of the vending machine.

[0056] like Fig.10 As shown, the present embodiment further provides a vending machine, including the above-mentioned pickup door installation structure. The pickup door 100 adopts a sliding movement form, has a simple structure, does not need to reserve a door opening space, saves occupied space, is easy to realize automation, and is convenient for users to take items.
