Description

Technical Field

[0001] The present invention relates to the technical field of automated control equipment, and in particular to a cabinet door opening and closing device and a courier cabinet having the same. Background Art

[0002] With the rapid development of the express logistics industry, the field of terminal automated delivery has received a lot of attention. The existing express cabinets used in automated delivery systems can basically only open the door automatically when the package is needed, but cannot close the door automatically. The recipient needs to close the door of the express cabinet. Although some express cabinets can open and close the door automatically, these express cabinets that can open and close the door automatically need to install a power system on each door, which is costly and has a small storage capacity. There are also some express cabinets with automatic door opening and closing that only have a relatively large express door. When the door is opened at once, all the express in the storage compartment will be exposed. At the same time, the storage compartments of these traditional express cabinets are fixed in size. Such express cabinets cannot make good use of their storage space, or there will be great restrictions on the size and shape of the stored express. At the same time, among the traditional express cabinet doors, many of those that can only pop open automatically cannot open the door more than 90°, which cannot fully expose the storage compartment for automatic loading, and thus cannot cooperate with automated equipment for automatic loading of express. As for those express cabinet doors that can automatically open the door completely, the doors are in an expanded state after opening and cannot be retracted into the express cabinet. This will block the automated loading equipment when loading the express, which is not conducive to rapid loading. Summary of the invention

[0003] In view of this, the present invention provides a cabinet door opening and closing device and an express cabinet having the same, wherein the cabinet door opening and closing device can automatically control the opening and closing of the cabinet door as needed.

[0004] The present invention provides a cabinet door opening and closing device, comprising a cabinet door opening and closing motor, a rotating shaft and a rotating ring, wherein the rotating ring comprises a power ring and a connecting ring, wherein the connecting ring is rotatably connected to the power ring, the power ring is fixedly connected to the rotating shaft, the connecting ring is fixedly connected to the cabinet door, and the cabinet door opening and closing motor drives the rotating shaft to rotate;

[0005] A closed driving surface is formed on the power ring, and a closed driven surface adapted to the closed driving surface is formed on the connecting ring. The closed driving surface drives the closed driven surface to rotate around the rotating shaft, thereby driving the cabinet door to close.

[0006] Furthermore, the connecting ring is coaxially arranged with the power ring. When the cabinet door is in a closed state, along the rotation direction of the cabinet door from opening to closing, the closing driving surface rotates at least 90° around the rotation axis through an idle travel area and then contacts the closing driven surface of the closed cabinet door.

[0012] Furthermore, the cabinet door opening and closing device is also provided with a cabinet door opening and closing slave transmission device, which transmits the power of the cabinet door opening and closing motor to the rotating shaft on the side of the cabinet body away from the cabinet door opening and closing motor. Driven by the cabinet door opening and closing motor, the cabinet door opening and closing device synchronously controls the cabinet doors on both sides of the cabinet body.

[0013] Furthermore, the cabinet door storage transmission device includes a second rotating shaft, the second rotating shaft is parallel to the first rotating shaft, a first gear is arranged on the first rotating shaft, a second gear is arranged on the second rotating shaft, the first gear and the second gear have the same number of teeth and are meshed with each other, a third pulley is also arranged on the second rotating shaft, and a fourth pulley is arranged on the rotating shaft on the side of the cabinet body away from the cabinet door opening and closing motor, and transmission is achieved between the third pulley and the fourth pulley through a second synchronous belt.

[0014] The present invention also provides an express delivery cabinet, comprising the cabinet door opening and closing device mentioned above.

[0015] To sum up, the present invention can automatically close the opened cabinet door through the setting of the cabinet door opening and closing device; further, by limiting the positional relationship between the closing driving surface and the closing driven surface, any opened cabinet door can be closed; further, the express cabinet can also control all cabinet doors to open to a preset angle at the same time to facilitate the taking and placing of express deliveries.

[0043] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description in conjunction with the accompanying drawings and preferred embodiments.

[0044] The present invention provides a cabinet door opening and closing device and an express cabinet having the same. The cabinet door opening and closing device can automatically control the opening and closing of the cabinet door as required.

[0045] Figure 1 A schematic diagram of the structure of a courier cabinet provided in an embodiment of the present invention. Figure 2 for Figure 1 Schematic diagram of the structure of the outer cabinet of the express cabinet. Figure 3 for Figure 1 Schematic diagram of the structure of the express cabinet after removing the outer cabinet body. Figure 4 for Figure 1 A structural diagram of the express cabinet from another perspective after removing the outer cabinet. Figure 5 for Figure 1 Front view of the express cabinet. Figure 6 for Figure 5 Schematic diagram of the cross-sectional structure along the VI-VI direction. Figure 7 This is a structural diagram when one side of the cabinet doors are fully opened. Figure 8 for Figure 7 Schematic diagram of the structure after the middle tray is taken out. Figures 1 to 8 The express cabinet provided by the embodiment of the present invention includes an outer cabinet 11 and an inner cabinet 12, the inner cabinet 12 is arranged in the outer cabinet 11, and a plurality of trays 13 arranged at intervals are arranged in the inner cabinet 12, and the trays 13 are detachably arranged in the express cabinet. When all the trays 13 are placed in the inner cabinet 12, the trays 13 divide the inner cabinet 12 into a plurality of storage units 14, and each storage unit 14 is provided with a cabinet door 15. The express cabinet is also provided with a control lock 16, such as an electronic ejection lock, and each control lock 16 is adapted to the position of a cabinet door 15. When the cabinet door 15 is closed, the control lock 16 locks the cabinet door 15, and when the control lock 16 is opened, the cabinet door 15 is opened.

[0046] In this embodiment, a slide 121 is formed on the inner wall of the express cabinet, and the tray 13 can be pulled out or put into the express cabinet along the slide 121. When the tray 13 is placed in the express cabinet, the slide 121 supports the tray 13.

[0047] Please continue to refer to Figure 4 A tray magnetic component 122 is provided inside the inner cabinet 12, preferably on the rear plate of the inner cabinet 12. When the tray 13 is completely placed in the express cabinet, one end of the tray 13 extending into the inner cabinet 12 is adsorbed on the tray magnetic component 122, so that the tray 13 can be fixed. The tray magnetic component 122 can also be used to detect whether the tray 13 is completely placed in the express cabinet when the tray 13 is placed in the express cabinet.

[0048] When placing items in the express cabinet, the location and number of trays 13 can be selected according to the volume of the items, so that multiple storage units 14 can be reorganized into a storage space. Figure 7 and Figure 8 As shown, when the volume of the items is small, an upper tray 13 can be placed on each slide 121. At this time, each storage unit 14 is a storage space, which increases the space utilization rate of the express cabinet.

[0049] In the above situation, when the express needs to be taken out, the control lock 16 on the cabinet door 15 corresponding to the storage unit 14 where the express is placed is opened, the cabinet door 15 of the storage unit 14 is opened, and the items placed in the storage unit 14 can be taken out.

[0050] When the volume of the item is large, such as larger than the volume of one storage unit 14, the item can occupy two or more storage units 14 as needed. In this case, some trays 13 may not be placed in the express cabinet, so that the volume of the storage space re-formed by the two storage units 14 adjacent to the missing trays 13 meets the needs of the item. At this time, the re-formed storage space corresponds to at least two cabinet doors 15.

[0051] In the above case, when it is necessary to take out the items, the control lock 16 opens all the cabinet doors 15 corresponding to the reorganized storage space so that the items in the storage space can be taken out.

[0052] In this embodiment, after an item is placed in the express cabinet, the space occupied by the item can be pre-stored in the control unit of the express cabinet. When the item is taken out, the control unit controls the corresponding control lock 16. The control unit that controls the control lock can be arranged in the interlayer 17 between the outer cabinet 11 and the inner cabinet 12.

[0053] In other embodiments, a detection device for detecting whether the tray 13 is placed is also provided at the placement of each tray 13 in the express cabinet. For example, the above-mentioned tray magnetic suction component 122 can also bear the function of detecting whether the tray 13 is placed in the inner cabinet 12. When the two cabinet doors 15 adjacent to the tray magnetic suction component 122 are closed, but the tray magnetic suction component does not detect the approach of the tray 13, it is determined that the two storage units 14 adjacent to the tray magnetic suction component are merged. When the items need to be taken out, the control unit simultaneously opens the cabinet doors 15 corresponding to the two storage units 14 adjacent to the tray magnetic suction component 122.

[0054] Fig. 9 The structure diagram of the cabinet door is shown in Figure 1. Fig.10 for Figure 6 The enlarged structural diagram of A in the middle. Please continue to see Figure 6 , Figure 8 , Fig. 9 and Fig.10 A first baffle 131 is provided on the tray 13. When the tray 13 is placed in the inner cabinet 12, the first baffle 131 faces the outside of the inner cabinet 12. When the two cabinet doors 15 adjacent to the tray 13 are closed, the first baffle 131 of the tray 13 corresponds to the position between the two cabinet doors 15. When one of the two cabinet doors 15 is opened, the other cabinet door 15 can block the tray 13 through the first baffle 131 to prevent the tray 13 from falling out.

[0055] like Figure 7 As shown, when the tray 13 is placed in the inner cabinet 12 , the outer side surface of the first baffle 131 is flush with the end surface of the inner cabinet 12 facing the cabinet door 15 .

[0056] A sealing strip 151 is further provided around the cabinet door 15 . When the cabinet door 15 is closed, the sealing strip 151 on the cabinet door 15 abuts against the first baffle 131 of the tray 13 to ensure the sealing performance of the storage units 14 on both sides of the tray 13 .

[0057] In this embodiment, a control lock accommodating portion 161 is provided in the middle of the inner cabinet body 12, and the control lock accommodating portion 161 divides the express cabinet into two independent spaces. In each independent space, a plurality of trays 13 are arranged longitudinally. In the control lock accommodating portion 161, two control locks 16 are arranged side by side to form opposite cabinet doors 15 on both sides of the control lock accommodating portion 161.

[0058] A buffer strip 111 is also provided on the outer cabinet body 11 at a position corresponding to the cabinet door 15 for buffering the cabinet door 15 when it is opened. At one end of each cabinet door 15 connected to the express cabinet, a position detector is also provided to detect whether the cabinet door is opened or fully opened.

[0059] Fig.11 This is a schematic diagram of the structure when all cabinet doors are opened. Fig.12 The following is a schematic diagram of the structure of the storage unit inside the storage box after adjustment. Fig.11 and Fig.12 As shown, through the above structure, the storage unit 14 in the express cabinet can be adjusted more conveniently. When the items are loaded into the express box by the automatic loading equipment, the tray 13 can be completely pulled out in advance. When loading, the items are first placed on the tray 13, and then the tray 13 is placed in the express cabinet to complete the automatic loading of the items. During the loading process, the storage unit 14 can be combined according to the needs to reasonably utilize the storage space of the express cabinet.

[0060] Fig.13 This is a schematic diagram of the structure after the express door is folded. Fig.14 It is a structural schematic diagram of a cabinet door opening and closing device and a cabinet door storage device. In the present embodiment, a mezzanine 17 is formed between the outer cabinet body 11 and the inner cabinet body 12, and a cabinet door opening and closing device 20 and a cabinet door storage device 30 are arranged in the mezzanine 17. The above-mentioned cabinet door 15 is rotatably connected to the cabinet door opening and closing device 20. After placing or taking out the express delivery, the cabinet door opening and closing device 20 can close the opened cabinet door 15. The cabinet door opening and closing device 20 is movably arranged on the cabinet door storage device 30. When the cabinet door 15 is opened, the cabinet door storage device 30 can drive the cabinet door opening and closing device 20 to move so that the cabinet door 15 is stored on the side of the express cabinet, such as in the mezzanine 17 between the inner cabinet body 12 and the outer cabinet body 11 (such as Fig.13 ).

[0061] Fig.15 It is a schematic diagram of the structure of the drive structure of the cabinet door opening and closing device. Fig.16 This is a schematic diagram of the connection between the cabinet door opening and closing device and the cabinet door. Fig.17 for Fig.16 The enlarged structural diagram at B in the figure is as follows: Fig.18 is a schematic diagram of the structure of the rotating ring. Fig.19 for Fig.18 Schematic diagram of the decomposed structure of the rotating ring. Fig. 20 The top view of the rotating ring after removing a connecting ring. Figures 15 to 20 In this embodiment, the cabinet door opening and closing device 20 includes a cabinet door opening and closing motor 21, a rotating shaft 22 and a rotating ring 23. The cabinet door opening and closing motor 21 drives the rotating shaft 22 to rotate. The rotating ring 23 is sleeved on the rotating shaft 22. The rotating ring 23 includes a power ring 231 and a connecting ring 232. The connecting ring 232 is rotatably connected to the power ring 231. The power ring 231 and the connecting ring 232 are coaxially arranged. The power ring 231 is fixedly connected to the rotating shaft 22, and the connecting ring 232 is fixedly connected to the cabinet door 15.

[0062] In this embodiment, the connecting ring 232 includes a first connecting ring 2321 and a second connecting ring 2322. The first connecting ring 2321 and the second connecting ring 2322 have the same shape and are respectively installed on the outer circumferential surface of the power ring 231 from the upper and lower end surfaces of the power ring 231. The rotating ring 23 is arranged between two cabinet doors 15, the first connecting ring 2321 is connected to the lower edge of one cabinet door 15, and the second connecting ring 2322 is connected to the upper edge of one cabinet door 15. In other words, the same rotating ring 23 is connected to two adjacent cabinet doors 15 through the first connecting ring 2321 and the second connecting ring 2322, respectively, and the upper edge and the lower edge of the same cabinet door 15 are respectively connected to two different rotating rings 23.

[0063] In this embodiment, the power ring 231 is fixed to the rotating shaft 22 by fasteners, such as fastening screws, and the connecting ring 232 is fixed to the cabinet door 15 by fasteners.

[0064] The rotating ring 23 also includes balls 233 and ball retaining plates 234. A ball receiving groove 235 is formed on one of the power ring 231 and the connecting ring 232. In the present embodiment, the ball receiving groove 235 is formed on the power ring 231. The ball retaining plate 234 is arranged on the other of the power ring 231 and the connecting ring 232. In the present embodiment, the ball retaining plate 234 is arranged on the connecting ring 232. The balls 233 and the ball retaining plate 234 are sandwiched between the connecting ring 232, the power ring 231 and the connecting ring 232, so that they can rotate relatively easily relative to the power ring 231.

[0065] like Fig.19 and Fig. 20 A driving block 236 is formed on the power ring 231. Preferably, the driving block 236 is a fan-shaped block along the axial direction of the power ring 231. In the rotation direction around the rotating shaft 22, an opening driving surface 2361 and a closing driving surface 2362 are formed on both sides of the driving block 236. Fig. 20 The opening driving surface 2361 and the closing driving surface 2362 are represented by the G surface and the P surface respectively. Preferably, the extension surfaces of the opening driving surface 2361 and the closing driving surface 2362 pass through the center of the power ring 231. A driven block 237 is formed on the connecting ring 232, which can also be a fan-shaped block. In the rotation direction around the rotating shaft 22, an opening driven surface 2371 and a closing driven surface 2372 are formed on both sides of the driven block 237. Fig. 20 The opening driven surface 2371 and the closing driven surface 2372 are represented by the F surface and the H surface, respectively. Similarly, the extension surfaces of the opening driven surface 2371 and the closing driven surface 2372 pass through the center of the power ring 231. The opening driving surface 2361 corresponds to the position of the opening driven surface 2371, and the closing driving surface 2362 corresponds to the position of the closing driven surface 2372. Fig. 20 As shown, when the rotating shaft 22 rotates in the clockwise direction, the opening driving surface 2361 presses the opening driven surface 2371, thereby driving the connecting ring 232 to rotate in the same direction as the rotating shaft 22; when the rotating shaft 22 rotates in the counterclockwise direction, the closing driving surface 2362 presses the closing driven surface 2372, thereby driving the connecting ring 232 to rotate in the same direction as the rotating shaft 22. Since the connecting block is connected to the cabinet door 15, the rotating ring 23 can realize the transmission of power from the rotating shaft 22 to the cabinet door 15.

[0066] Furthermore, an idle travel area 238 is formed between the opening driving surface 2361 and the opening driven surface 2371, and between the closing driving surface 2362 and the closing driven surface 2372. The idle travel area 238 means that the opening driving surface 2361 and the opening driven surface 2371, and the closing driving surface 2362 and the closing driven surface 2372 are not always in contact, and in some specific states, the opening driving surface 2361 needs to rotate through a certain idle travel area 238 before it can achieve contact with the opening driven surface 2371, and the closing driving surface 2362 also needs to rotate through a certain idle travel area 238 before it can achieve contact with the closing driven surface 2372.

[0067] In this embodiment, when the cabinet door 15 is in the closed state, along the rotation direction of the cabinet door 15 from opening to closing, the closing driving surface 2362 will contact the closed driven surface 1272 of the closed cabinet door 15 after rotating at least 90° around the rotation axis 22. In other words, when the cabinet door 15 is in the closed state, the control lock 16 will pop the cabinet door 15 open, and the opening driven surface 2371 connected to the cabinet door 15 needs to rotate at least 90° around the rotation axis 22 before contacting the opening driving surface 2361 corresponding to the cabinet door 15. Preferably, when the cabinet door 15 is closed, the central angles of the corresponding idle travel areas 238 between the opening driving surface 2361 and the opening driven surface 2371, and between the closing driving surface 2362 and the closing driven surface 2372 (see Fig. 20 The α) of is 90°.

[0068] In this embodiment, there are multiple cabinet doors 15 connected to the same rotating shaft 22. When in use, only one or a few cabinet doors 15 may be in an open state, while the other cabinet doors 15 are in a closed state. Fig. 20 For example, assume that the clockwise direction is the rotation direction when the cabinet door 15 is opened, and the counterclockwise direction is the rotation direction when the cabinet door 15 is closed. When one of the cabinet doors 15 is opened, the connecting ring 232 connected to the cabinet door 15 will rotate in the clockwise direction relative to the power ring 231, that is, the closed driven surface 2372 on the connecting ring 232 will move in the direction of the closed driving surface 2362. At this time, if the cabinet door 15 is opened at 90°, the closed driven surface 2372 on the connecting ring 232 will contact the closed driving surface 2362. The connecting rings 232 of the other cabinet doors 15 that have not been opened will remain stationary. At this time, the central angle corresponding to the idle travel area 238 between the closed driven surface 2372 of the stationary connecting ring 232 and the closed driving surface 2362 is still 90°.

[0069] After the items are taken out of the express cabinet, the cabinet door opening and closing motor 21 drives the rotating shaft 22 to rotate counterclockwise in FIG. 20, and the closing driving surface 2362 can drive the closing driven surface 2372 to move, thereby pushing the cabinet door 15 back to the closed state, thereby realizing the automatic closing of the cabinet door 15. Due to the existence of the idle travel area 238, for the unopened express door, the closing driving surface 2362 needs to rotate 90° before it can contact the closing driven surface 2372. This enables the closing process of the rotating shaft 22 on a single cabinet door 15 to not affect other unopened cabinet doors 15. After closing the opened cabinet door 15, the rotating shaft 22 rotates back to its original position and waits for the next action.

[0070] When all the cabinet doors 15 are opened, the rotating shaft 22 can also drive the power ring 231 to rotate in a clockwise direction, so that the cabinet doors 15 can all be opened to a certain angle, such as 90°.

[0071] Furthermore, the opening driving surface 2361, the opening driven surface 2371, the closing driving surface 2362 and the closing driven surface 2372 are all flexible surfaces. When the opening driving surface 2361 contacts the opening driven surface 2371, the two surfaces can be deformed to a certain extent through pressure to reduce the impact of the entire cabinet door 15 opening and closing process, and prevent the connection ring 232 and the power ring 231 from having errors in the stroke during the opening and closing process, thereby preventing damage to surrounding components.

[0072] More specifically, the cabinet door opening and closing motor 21 is connected to the first rotating shaft 24 through a coupling, a first pulley 241 is provided on the first rotating shaft 24, and a second pulley 221 is provided on the rotating shaft 22, and a first synchronous belt 251 is provided between the first pulley 241 and the second pulley 221. The cabinet door opening and closing motor 21 drives the rotating shaft 22 to rotate through the first pulley 241, the first synchronous belt 251 and the second pulley 221.

[0073] In order to save parts and facilitate the synchronization of opening and closing of multiple rows of cabinet doors 15, in this embodiment, see Fig.14 and Fig.24On the side where the door opening and closing motor 21 of the express cabinet is located, a second rotating shaft 26 parallel to the first rotating shaft 24 is also provided. A first gear 242 is provided on the first rotating shaft 24, and a second gear 261 is provided on the second rotating shaft 26. The first gear 242 and the second gear 261 have the same number of teeth and mesh with each other. A third pulley 262 is also provided on the second rotating shaft 26, and a fourth pulley 222 is also provided on the rotating shaft 22 on the other side of the express cabinet relative to the door opening and closing motor 21. The third pulley 262 and the fourth pulley 222 are driven by a second synchronous belt 252. The second synchronous belt 252 connects the third pulley 262 and the fourth pulley 222 on both sides of the express cabinet through the interlayer 17 between the lower plate of the inner cabinet body 12 and the lower plate of the outer cabinet body 11.

[0074] The power of the door opening and closing motor 21 is transmitted to the second rotating shaft 26 through the first gear 242 and the second gear 261, and the power on the second rotating shaft 26 is transmitted to the other side of the express cabinet through the third pulley 262, the second synchronous belt 252 and the fourth pulley 222 to control the rotating shaft 22 on the other side. That is, if the side where the door opening and closing motor 21 is located is called the active side, then the side of the express cabinet relative to the door opening and closing motor 21 can be called the driven side. In this embodiment, the power of the door opening and closing motor 21 is transmitted from the active side to the driven side by setting the door opening and closing transmission device, and synchronous control is performed in the control of opening or closing the cabinet door 15.

[0075] It should be noted that, due to the meshing arrangement of the first gear 242 and the second gear 261, the rotation directions of the first rotating shaft 24 and the second rotating shaft 26 are opposite. When the cabinet door opening and closing motor 21 rotates, the rotation direction of the rotating shaft 22 on the driven side is also opposite to the rotation direction of the rotating shaft 22 on the active side. This can just achieve Fig.11 In the embodiment, the doors 15 on both sides of the express cabinet are opened or closed synchronously and symmetrically, that is, the doors 15 on the two rows of the express cabinet are double-doors.

[0076] It can be understood that in this embodiment, the express cabinet has only two rows. In other embodiments, the express cabinet may have more rows, and the cabinet door opening and closing slave transmission device may be set again to lead the power from the active side. At this time, the transmission component may be set according to the need of the cabinet door 15 opening direction so that the introduced power conforms to the rotation direction of the rotating shaft there.

[0077] In this embodiment, only the case where the cabinet door opening and closing device 20 is applied to the express cabinet is described. In fact, the cabinet door opening and closing device 20 can also be applied to other cabinets with cabinet doors that can be opened and closed by rotation, such as wardrobes, storage cabinets or shoe cabinets. When the cabinet door opening and closing device 20 is set on the above-mentioned various cabinets, it can control the closing of a single or multiple cabinet doors 15 when other cabinet doors 15 are closed, and can open multiple cabinet doors 15 to a predetermined angle at the same time.

The rotating shaft connecting seat 271 is fixed on the cabinet door storage device 30, and the rotating shaft fixing block 272 is fixed on the rotating shaft connecting seat 271, and the bearing 273 is clamped between the rotating shaft fixing block 272 and the rotating shaft connecting seat 271. An oil storage hole 274 is also provided on the bearing 273 to store grease. After the rotating shaft connecting seat 271 and the rotating shaft fixing block 272 are combined, the grease is sealed in the bearing 273. When the rotating shaft 22 rotates, the grease will overflow between the rotating shaft 22 and the bearing 273. This can reduce the resistance and wear of the rotating shaft 22 when it rotates.
