Description

Technical Field

[0001] This utility model relates to the field of parcel boxes, and more specifically, to a weighing feedback parcel box. Background Technology

[0002] In some detached houses, residents typically have a separate parcel locker for receiving packages and mail. Delivery personnel will place packages in the locker and notify the resident by phone or text message. The resident will then go to collect the package after receiving the notification.

[0003] However, most parcel lockers in the current technology have a low level of intelligence and only serve as storage devices. When users miss a call or ignore a text message notification, the parcel will remain in the parcel locker for a long time. Moreover, when there are many loose parcels stored in the parcel locker, users often forget to pick up their parcels. Users will face many inconveniences when using parcel lockers.

[0004] For example, Chinese patent document (publication number CN 211087412 U) discloses a home-use smart parcel locker, including: a locker body, a pickup door, and a drop-off door. The drop-off door is pivotally connected to the locker body and located within the parcel transfer cavity, with a parcel transfer slot defined within it. When the drop-off door is open, it opens the drop-off opening and closes the channel between the parcel receiving cavity and the parcel transfer cavity. When the drop-off door is closed, it closes the drop-off opening, and the parcel transfer slot connects to the parcel receiving cavity. An electronic drop-off lock is provided between the drop-off door and the locker body. It can be equipped with a first controller that is connected to the user in real time, allowing the user to determine whether a parcel has been deposited based on the status of the first controller, thus facilitating the user's monitoring of the locker's status.

[0005] However, the aforementioned home smart parcel lockers (parcel lockers) use a camera network connected to the Internet of Things to monitor parcel delivery. This results in high manufacturing and maintenance costs, low accuracy, frequent misjudgments, and users cannot be sure that their parcels have been completely retrieved after picking them up.

[0006] The relevant technologies do not provide effective solutions to the above problems. Utility Model Content

[0007] This application provides a weighing feedback parcel locker to solve the problem that existing parcel lockers cannot efficiently provide users with feedback on the storage and retrieval status of parcels.

[0012] Furthermore, both the delivery door and the retrieval door are located on the front wall of the box; the delivery door can rotate around a horizontal line to open or close; the retrieval door can rotate around a vertical line to open or close.

[0013] Furthermore, it also includes an anti-theft panel, one side of which is hinged to the inner wall of the box body, which is opposite to the front wall of the box body. The middle part of the anti-theft panel is hinged to the middle part of the delivery door via a connecting rod. When the delivery door is open, the delivery door drives the anti-theft panel to rotate via the connecting rod, and the delivery door and the anti-theft panel overlap in the horizontal direction, thus forming an anti-theft surface together. When the delivery door is closed, the delivery door drives the anti-theft panel to rotate via the connecting rod, the anti-theft panel returns to its original position, and the delivery door and the anti-theft panel move away from each other.

[0014] Furthermore, the delivery door includes an outer door panel, an inner panel, and an extension plate; the outer door panel is hinged to the front wall of the box body, the inner panel is fixed to the upper and two sides inside the outer door panel, and the inner panel is perpendicular to the outer door panel; the extension plate is fixed to the middle of the inner panel, and the extension plate extends downward toward the outer door panel; wherein, the extension plate extends downward beyond the outer door panel, thereby forming the anti-theft surface together with the anti-theft panel.

[0015] Furthermore, a solar panel is provided on the front wall of the box, and the solar panel is located between the delivery door and the retrieval door. The solar panel is electrically connected to a battery, and the battery is electrically connected to the weighing device and the controller.

[0016] Furthermore, the cabinet is divided into a letter cabinet and a parcel cabinet, which are separated by a partition. The letter cabinet is located on top of the parcel cabinet, and its volume is smaller than that of the parcel cabinet. The delivery door and the retrieval door are hinged to the parcel cabinet. The outer wall of the letter cabinet is hinged with a retrieval door, and the middle of the retrieval door is hinged with a letter delivery door.

[0017] Furthermore, an antenna is provided on the top of the enclosure, and the controller communicates with the Internet of Things via the antenna, thereby establishing communication with smart terminals.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0040] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0041] This application provides a weighing feedback type parcel box, such as Figure 1 , 2 As shown, it includes a housing 100, a weighing mechanism 200, and a controller.

[0042] like Figure 1 , 2 As shown, the box body 100 is hinged with a delivery door 300 and a pickup door 400. The pickup door 400 is located below the delivery door 300. The courier puts the package into the box body 100 through the delivery door 300, and the user takes the package out of the box body 100 through the pickup door 400. Optionally, the delivery door 300 is not equipped with a lock, while the pickup door 400 is equipped with a lock.

[0043] Optionally, the delivery door 300 may be located on the top of the box 100 or on the front wall of the box 100, and the retrieval door 400 may be located on the front wall or the rear wall of the box 100; there are no restrictions on this.

[0044] The controller is located inside the enclosure 100. The controller is connected to the Internet of Things (IoT) to establish communication feedback with the user's smart terminal, which can be a mobile phone, computer, or tablet, etc.

[0045] like Figures 2 to 4 As shown, the weighing mechanism 200 is located at the bottom of the box 100. The weighing mechanism 200 includes a support plate 210, a weighing device 220, a mounting box 230, and a support structure 240. The support structure 240 is located at the bottom of the weighing mechanism 200 and is fixedly connected to the side wall of the box 100. This support structure 240 serves as the bottom surface of the parcel box and can be plate-shaped or rod-shaped; no limitation is made here. The upper side of the support structure 240 is fixedly connected to the mounting box 230. The weighing device 220 is installed inside the mounting box 230, with its upper part extending from the top of the mounting box 230. The weighing device 220 is communicatively connected to the controller. The support plate 210 is fixedly connected to the top of the weighing device 220. The support plate 210 is used to support the parcel and allows the weighing device 220 to detect the weight of the parcel.

[0046] Optionally, the communication connection between the weighing device 220 and the controller can be either a wired communication connection or a wireless communication connection.

[0047] Specifically, the enclosure 100 is equipped with an antenna 500, through which the controller communicates with the Internet of Things and establishes communication with smart terminals. The antenna 500 is preferably located on the top of the enclosure 100.

[0048] In this way, when a package is delivered through the delivery gate 300, it falls onto the support plate 210. The weighing device 220 detects an increase in weight and transmits a signal to the controller. The controller then feeds back to the Internet of Things (IoT), which in turn pushes a notification to the user that the package has been stored in the package box. The user can then be notified in real time via their smart terminal that a package has been delivered to the package box. When the user retrieves a package through the collection gate 400, the weighing device 220 detects a decrease in weight and transmits a signal to the controller. The controller then feeds back to the IoT, which in turn pushes a notification to the user that the package has been retrieved from the package box. The user can then be notified via their smart terminal that a package has been retrieved and can confirm whether the package has been completely retrieved. For example, if the weighing device does not detect any weight, the package has been completely retrieved.

[0049] In detail, from the perspective of communication technology implementation, the controller and the user's smart terminal are connected to the Internet of Things through wireless communication modules to form a data channel. The controller uploads the status signal of the weighing device 220 to the Internet of Things cloud server and feeds it back to the smart terminal, thereby reminding the user of the status of the package box in real time. The specific communication and propagation technology is existing technology and will not be described in detail here.

[0050] Therefore, by adopting the weighing feedback parcel box of this application, users can efficiently know the status of the parcels in the parcel box through the real-time feedback of the weighing device 220, preventing the forgetting or omission of parcels and significantly improving the user experience. The load-bearing mechanism also serves as the bottom load-bearing component of the parcel box, which can reduce the space occupied inside the parcel box and has low manufacturing and maintenance costs. The mounting box 230, together with the support structure 240, can also protect the weighing device 220, preventing the weighing device 220 from being directly immersed in water in rainy weather.

[0051] Preferably, such as Figure 3 , 4 As shown in Figure 5, a stabilizer 250 is fixedly connected to the lower side of the support plate 210. The stabilizer 250 can be block-shaped, rod-shaped, or plate-shaped. In one detailed embodiment, the stabilizer 250 is composed of several rods spliced ​​together, extending along the surface of the support plate 210. This stabilizer 250 can increase the weight of the support plate 210, reduce its swaying, and increase the accuracy of the weighing device 220 in detecting packages.

[0052] Specifically, the weighing device 220 is a cantilever sensor. The lower side of the support plate 210 is fixedly connected to the weighing device 220 via a stabilizer 250. For example... Figure 4 , 5 As shown, the stabilizer 250 includes a fixing rod 251, which is fixed to one side of the top of the weighing device 220. The other side of the weighing device 220 is offset from the stabilizer 250 to prevent the stabilizer 250 from interfering with the operation of the weighing device 220.

[0053] More specifically, such as Figure 5 As shown, the bottom of the side of the weighing device 220 that is offset from the stabilizer 250 is a certain distance from the bottom of the mounting box 230, which also provides space for the normal operation of the weighing device 220.

[0054] In detail, the cantilever beam sensor used in this embodiment is a measuring device that uses the principle of bending deformation of a cantilever beam under force to convert weight or force into an electrical signal through strain gauges. It has a simple structure and high accuracy. When the package box receives a lighter letter, the weighing device 220 can accurately detect the weight change and thus alert the user.

[0055] More specifically, there is a gap between the outer edge of the support plate 210 and the inner wall of the box 100, which allows the support plate 210 to float slightly for weighing operations.

[0056] Preferably, the support structure 240 consists of several rods. (Refer to...) Figure 4As shown, the support structure 240 includes two longitudinal rods 241 and several transverse rods 242. The two longitudinal rods 241 are fixedly connected to the two side walls of the box 100, respectively. The transverse rods 242 are connected between the two longitudinal rods 241. The mounting box 230 is fixedly connected to the transverse rods 242. The support structure 240 allows the space under the bearing plate 210 to communicate with the external space, which is convenient for cleaning and ventilation.

[0057] As a comparison, if the support structure 240 uses a plate to enclose the lower side of the box 100, then when water seeps from the bottom of the box, the water will be difficult to drain from the plate in time and will easily accumulate between the bearing plate 210 and the support structure 240. The corresponding space is also difficult to clean and is prone to corrosion.

[0058] As a specific embodiment, both the delivery door 300 and the retrieval door 400 are located on the front wall of the housing 100. The delivery door 300 can rotate around a horizontal line to open or close. The retrieval door 400 can rotate around a vertical line to open or close. Specifically, the lower side of the delivery door 300 is hinged to the housing 100, and the left or right side of the retrieval door 400 is hinged to the housing 100.

[0059] Preferred, such as Figure 6 As shown, it also includes an anti-theft panel 600, one side of which is hinged to the inner wall of the box 100, which is opposite to the front wall of the box 100. The middle part of the anti-theft panel 600 is hinged to the middle part of the delivery door 300 via a connecting rod 610.

[0060] like Figure 7 As shown, when the delivery door 300 is opened, the delivery door 300 drives the anti-theft plate 600 to rotate via the connecting rod 610. The delivery door 300 and the anti-theft plate 600 overlap in the horizontal direction, thus forming an anti-theft surface together. The delivery person can place the package on the anti-theft surface. Figure 6 As shown, when the delivery door 300 is closed, the delivery door 300 drives the anti-theft plate 600 to rotate via the connecting rod 610. The anti-theft plate 600 is reset, and the delivery door 300 and the anti-theft plate 600 move away from each other. The package falls from the gap between the delivery door 300 and the anti-theft plate 600 to the top of the support plate 210 due to gravity.

[0061] This design effectively protects the packages at the bottom of the parcel box when the delivery door 300 is open, preventing theft. When the package is placed on the anti-theft surface, the anti-theft plate 600 and the delivery door 300, combined with the connecting rod 610, can also support the package to a certain extent, minimizing the risk of the parcel box closing abruptly and reducing security risks.

[0062] Specifically, such as Figure 7 , 8As shown, the delivery door 300 includes an outer door panel 310, an inner cladding panel 320, and an extension panel 330. The outer door panel 310 is hinged to the front wall of the housing 100. The inner cladding panel 320 is fixed to the upper and side sides of the outer door panel 310, and the inner cladding panel 320 is perpendicular to the outer door panel 310. The extension panel 330 is fixed to the middle of the inner cladding panel 320 and extends downward toward the lower side of the outer door panel 310. The extension panel 330 extends downward beyond the outer door panel 310, thus forming an anti-theft surface together with the anti-theft panel 600. The inner cladding panel 320 and the extension panel 330 together form a space for placing packages, which prevents packages from sliding out of the delivery door 300 when it is opened.

[0063] Preferred, such as Figure 8 As shown, the inner circumference panels 320 on both sides of the outer door panel 310 are provided with limiting protrusions 321. The limiting protrusions 321 protrude toward the inner wall of the box 100. When the outer door panel 310 is rotated to a certain angle, the limiting protrusions 321 can be locked onto the inner wall of the box 100 to limit the opening of the outer door panel 310. When wrapped on the anti-theft surface, this design can also prevent the outer door panel 310 from over-flipping and causing the package to slip off from the delivery door 300.

[0064] To further meet energy-saving requirements, such as Figure 9 As shown, a solar panel 700 is installed on the front wall of the housing 100. The solar panel 700 is positioned between the delivery door 300 and the retrieval door 400, meaning that the solar panel 700 is arranged vertically, which can effectively prevent the accumulation of water and dust. The solar panel 700 is electrically connected to a battery, which is electrically connected to the weighing device 220 and the controller to provide power.

[0065] Preferred, such as Figure 9 As shown, the cabinet 100 is divided into a letter cabinet 110 and a parcel cabinet 120, separated by a partition 130. The letter cabinet 110 is located above the parcel cabinet 120, and its volume is smaller than that of the parcel cabinet 120, thus allowing it to be used specifically for thinner letters. The delivery door 300 and the retrieval door 400 are hinged to the parcel cabinet 120, allowing it to accommodate larger parcels. This design effectively adapts to user habits; the letter cabinet 110 requires minimal space and is positioned high within the parcel cabinet, making it convenient for users to retrieve and check for any missing letters.

[0066] like Figure 9 As shown, the outer wall of the mail cabinet 110 is hinged with a mail retrieval door 111, and the middle of the mail retrieval door 111 is hinged with a mail delivery door 112, thereby further saving space.

[0067] Preferably, the controller is located inside the mailbox 110, making it convenient for users to open the mailbox 110 from the top of the mailbox to inspect the controller.

[0068] In this application, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0069] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
