Description

Technical Field

[0001] This invention relates to the field of express delivery locker technology, specifically to an internet-based express delivery locker. Background Technology

[0002] Internet-connected smart parcel lockers, also known as smart parcel lockers, are a product of the integration of the Internet and the Internet of Things. Widely distributed in residential communities and office buildings, parcel lockers allow couriers to deposit packages, generating a retrieval code that is sent to the recipient via SMS. Recipients can then retrieve their packages at a designated time using the code, by scanning a QR code, or by facial recognition. The retrieval information is recorded and updated. Their advantages are significant: for couriers, they greatly improve delivery efficiency by eliminating waiting time and allowing for faster handling of multiple packages; for recipients, they provide 24-hour self-service, offering flexibility and allowing for convenient retrieval at any time; and for property management, they reduce management pressure and prevent package accumulation and loss. However, currently, to prevent accidents such as children or small animals getting trapped if recipients forget to close the locker, larger parcel lockers are often placed on top. However, shorter individuals may not be able to reach the retrieval opening due to height limitations, requiring them to tiptoe or even jump to open the locker, a process that is both inconvenient and poses certain safety hazards.

[0003] By combining the above issues, we can see that the existing express delivery lockers on the market cannot simultaneously avoid the problems mentioned above when in use, thus failing to achieve the desired effect. Therefore, we propose an internet-based express delivery locker. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention solves the problem of people being unable to reach the pickup opening of the express cabinet due to height limitations by setting up a lifting component. Shorter recipients no longer need to use troublesome and dangerous methods such as tiptoeing or jumping to open the cabinet door. They can easily retrieve the express delivery located at a high position by simply standing on the lifting platform, which greatly simplifies the pickup process and saves time and energy.

[0016] 2. By setting up a drive component, this invention addresses the issue that during the pickup process, the pickup personnel may need to adjust their holding posture or rearrange multiple packages. If the roller suddenly rotates, the packages may lose balance and fall. Some larger or heavier packages falling may injure the pickup personnel's feet or legs. Delaying the rotation allows the pickup personnel time to stabilize the packages, preventing items from falling and injuring people due to the sudden start of the roller.

[0017] 3. By setting up a moving component, the recipient stands on the lifting platform to retrieve the package located at a high position during the lifting process. After the package is retrieved, the moving door closes, which can effectively prevent the recipient from accidentally falling from the edge of the lifting platform when leaving. This protective measure can greatly reduce the probability of accidents, especially for children, the elderly, or people with mobility impairments, and provide reliable safety protection for users.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-3 The present invention provides a technical solution: an Internet-based express locker, including a locker body 1, a lifting mounting box 2 fixedly installed on the side of the locker body 1, a drive mounting box 3 fixedly installed on the side of the lifting mounting box 2, a height-increasing box 4 fixedly installed on the side of the lifting mounting box 2, a lifting component 10 disposed inside the lifting mounting box 2, a drive component 20 disposed inside the drive mounting box 3, the lifting component 10 and the drive component 20 working together, a moving component 30 disposed inside the lifting mounting box 2, and a moving door 302 disposed on the top of the drive mounting box 3; Lifting assembly 10 is used to raise the height of the person picking up the package; Drive component 20 is used to drive lifting component 10; The movable component 30 is used to drive the sliding door 302 to slide.

[0022] As a further definition of the lifting assembly 10 of the present invention, the lifting assembly 10 includes sliding grooves 101 respectively opened on both sides of the lifting mounting box 2, a lifting plate 102 is slidably mounted on the surface of the lifting mounting box 2, two sliding plates 103 are fixedly connected to the bottom of the lifting plate 102, the sliding plates 103 are slidably engaged with the sliding grooves 101, a primary rotating roller 105 is rotatably connected between the two sliding plates 103, and a secondary rotating roller 106 is rotatably connected to the inner wall of the lifting mounting box 2, the secondary rotating roller 106 extending to the outer side of the lifting mounting box 2.

[0023] A primary drive gear 107 and a secondary drive gear 108 are respectively fixedly sleeved in the middle of the primary rotating roller 105 and the secondary rotating roller 106. The primary drive gear 107 and the secondary drive gear 108 are rotatably meshed. Two first rotating columns 109 and two second rotating columns 110 are also fixedly sleeved on the outer sides of the primary rotating roller 105 and the secondary rotating roller 106, respectively. The first rotating columns 109 and the second rotating columns 110 are in contact with each other. The primary drive gear 107, the secondary drive gear 108, the first rotating columns 109, and the second rotating columns 110 are respectively eccentrically set with the primary rotating roller 105 and the secondary rotating roller 106. A guardrail 111 is fixedly connected to the surface of the lifting plate 102. A signal receiver is provided on the side of the lifting installation box 2.

[0024] The specific implementation of this embodiment is as follows: When the recipient needs to retrieve the package located in the top large package locker, the signal receiver receives the signal and immediately starts the drive source. The drive source indirectly drives the secondary rotating roller 106 to rotate, and the secondary drive gear 108 installed on its side also rotates synchronously. At the same time, the rotation of the secondary drive gear 108 will drive the primary drive gear 107 to rotate. The eccentric setting of the primary drive gear 107 and the secondary drive gear 108 makes the distance between the primary rotating roller 105 and the secondary rotating roller 106 closer and farther when the primary drive gear 107 and the secondary drive gear 108 start to rotate. The sliding plate 103 connected to the primary rotating roller 105 will slide up and down along the sliding grooves 101 on both sides of the lifting mounting box 2, causing the lifting plate 102 to rise or fall. At the same time, in order to ensure the safety of the recipient, a protective railing 111 is fixedly connected to the surface of the lifting plate 102, so that the recipient can smoothly retrieve the large package located at the top by standing on the lifting plate 102. It should be noted that the drive source will only restart to lower the lifting plate 102 when the cabinet door is closed.

[0025] Example 2 Please see Figures 4-5 The present invention provides a technical solution: an Internet-based express delivery locker. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0026] As a further definition of the drive assembly 20 of the present invention, the drive assembly 20 includes a transmission gear 201 sleeved on the outside of the secondary rotating roller 106, a drive shaft 202 and a drive shaft 203 rotatably connected to the side of the lifting mounting box 2, a drive gear 2021 fixedly connected to the outside of the drive shaft 202, and a drive gear body 2031 fixedly connected to the outside of the drive shaft 203. The transmission gear 201, the drive gear 2021 and the drive gear body 2031 mesh with each other.

[0027] A worm gear 204 is fixedly connected to the outside of the drive gear body 2031. Two mounting plates 205 are fixedly connected to the side of the lifting mounting box 2. A worm gear 206 is rotatably connected between the two mounting plates 205. A first rotating rod 207 is rotatably connected to the side of the mounting plate 205. One end of the first rotating rod 207 passes through one of the mounting plates 205 and is fixedly connected to one end of the worm gear 206.

[0028] A second rotating rod 208 is rotatably connected to the end of the first rotating rod 207. A first spiral spring 209 is sleeved on the outer side of both the first rotating rod 207 and the second rotating rod 208. One end of the first spiral spring 209 is fixedly connected to the surface of the first rotating rod 207, and the other end of the first spiral spring 209 is fixedly connected to the surface of the second rotating rod 208. A mounting block 210 is fixedly connected to the side of the lifting mounting box 2. A servo motor 211 is fixedly connected to the side of the mounting block 210. The output shaft of the servo motor 211 is fixedly connected to the end of the second rotating rod 208.

[0029] The specific implementation of this embodiment is as follows: The output shaft of the servo motor 211 drives the second rotating rod 208 to rotate synchronously. When the second rotating rod 208 rotates, the first spiral spring 209 begins to tighten, and its stored elastic potential energy continuously increases. When the elastic potential energy reaches a certain level, it will drive the first rotating rod 207 to start rotating. The rotation of the first rotating rod 207 drives the worm gear 206 to rotate synchronously. At the same time, the worm gear 206 meshes with the worm wheel 204, and the transmission gear 201, the drive gear 2021 and the drive gear body 2031 mesh with each other, ultimately causing the secondary rotating roller 106 to rotate with a delay. During the pickup process, the pickup personnel may need to adjust the picking posture of the package or reorganize multiple packages. If the secondary rotating roller 106 rotates suddenly, the package may lose balance and fall. Some larger or heavier packages may fall and injure the feet or legs of the pickup personnel. The delayed rotation allows the pickup personnel time to stabilize the package and avoid the items falling and injuring people. It should be noted that the first spiral spring 209 is made of titanium alloy.

[0030] Example 3 Please see Figures 6-10The present invention provides a technical solution: an Internet-based express delivery locker. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0031] As a further definition of the moving component 30 of the present invention, the moving component 30 includes a limiting groove 301 formed on the surface of the lifting plate 102, the moving door 302 is slidably connected to the surface of the lifting plate 102, a limiting block 303 is fixedly connected to the bottom of the moving door 302, the limiting block 303 is slidably engaged with the limiting groove 301, and a return spring 320 is connected between the limiting block 303 and the limiting groove 301.

[0032] The lifting mounting box 2 has an internal mounting cavity 304. A rack plate 305 is slidably connected to the inner wall of the mounting cavity 304. One end of the rack plate 305 is fixedly connected to the bottom of the lifting plate 102. A first rotating shaft 306 is also rotatably connected to the inner wall of the mounting cavity 304. A first gear 307 is fixedly connected to the outer side of the first rotating shaft 306. The rack plate 305 and the first gear 307 mesh and drive each other. A second rotating shaft 308 is also rotatably connected to the inner wall of the mounting cavity 304. A second gear 309 is fixedly connected to the outer side of the second rotating shaft 308. The second gear 309 meshes with the first gear 307.

[0033] The second rotating shaft 308 is fixedly connected to a drive column 310 at one end, and a drive column 311 is rotatably connected to the other end of the drive column 310. A second spiral spring 312 is fixedly sleeved on the outer side of the drive column 310 and the drive column 311. One end of the second spiral spring 312 is fixedly connected to the side of the drive column 310, and the other end of the second spiral spring 312 is fixedly connected to the side of the drive column 311.

[0034] One end of the drive column 311 is fixedly connected to a pull rope 313. The outer side of the pull rope 313 is connected to the inner wall of the mounting cavity 304 by a first through groove 314. The inner wall of the first through groove 314 is rotatably connected to a first pulley 316. The inside of the lifting plate 102 is provided with a second through groove 317. The inner wall of the second through groove 317 is rotatably connected to a second pulley 318. The first through groove 314, the second through groove 317 and the limiting groove 301 are connected. The pull rope 313 passes through the inside of the first through groove 314, the second through groove 317 and the limiting groove 301, and passes through the side of the first pulley 316 and the second pulley 318. The other end of the pull rope 313 is fixedly connected to the side of the limiting block 303.

[0035] The specific implementation of this embodiment is as follows: The lifting plate 102 rises, causing the rack plate 305 to rise. The rack plate 305 meshes with the first gear 307, which in turn meshes with the second gear 309. The rotation of the first gear 307 further drives the second gear 309 to rotate, causing the second rotating shaft 308 to rotate as well. The rotation of the second rotating shaft 308 directly drives the rotating column 310 to rotate. When the rotating column 310 rotates, in the initial state, the second spiral spring 312 is in a tightened state and stores a certain amount of elastic potential energy. As the rotating column 310 rotates, the second spiral spring 312 gradually relaxes, and one end of the second spiral spring 312... One end is fixed to the side of the drive column 310, and the other end is fixed to the side of the drive column 311. The drive column 311 is wrapped with the pull rope 313. When the second spiral spring 312 relaxes, its elastic potential energy is released, which drives the pull rope 313 wrapped with it to reverse and relax. The pull rope 313 changes from a relatively tight state to a relatively loose state. The reset spring 320 pushes the limit block 303 to slide with the limit groove 301, thereby driving the sliding door 302 to move and close. When the express delivery is picked up, the drive column 310 reverses, the pull rope 313 is wrapped around the outside of the drive column 310, and the pull rope 313 pulls the sliding door 302 to reset. The sliding door 302 opens, which avoids the recipient from falling as much as possible.
