[0025] The present application discloses a parcel box with weighing feedback as in the Fig. 1 and Fig. 2, comprising a housing 100, a weighing mechanism 200 and a control unit.

[0026] As in the Fig. 1 and Fig. As shown in Figure 2, the housing 100 includes a hinged delivery door 300 and a removal door 400, with the removal door 400 located below the delivery door 300. The delivery person inserts the package into the housing 100 through the delivery door 300, while the user removes the package from the housing 100 through the removal door 400. Optionally, the delivery door 300 is not equipped with a lock, while the removal door 400 is equipped with a lock.

[0027] Optionally, the delivery door 300 is located on the top of the housing 100 or on the front wall of the housing 100, while the removal door 400 is located on the front wall of the housing 100 or on the rear wall of the housing 100, with no limitation in this regard.

[0028] The control unit is located within the housing 100 and communicates with the user's smart device via an IoT communication link. The smart device can be a mobile phone, a computer, or a tablet.

[0029] As in the Fig. As shown in Figures 2 to 4, the weighing mechanism 200 is arranged at the bottom of the housing 100, wherein the weighing mechanism 200 comprises a support plate 210, a weighing device 220, a mounting housing 230, and a support structure 240. The support structure 240 is arranged at the bottom of the weighing mechanism 200 and is firmly connected to the side wall of the housing 100. This support structure 240 serves as the bottom surface of the parcel box and can be either plate-shaped or rod-shaped, without being limited thereto. The top side of the support structure 240 is firmly connected to the mounting housing 230. The weighing device 220 is arranged in the mounting housing 230, wherein the upper part of the weighing device 220 protrudes from the top side of the mounting housing 230 and the weighing device 220 is communicatively connected to the control unit.The support plate 210 is fixedly attached to the top of the weighing device 220, wherein the support plate 210 serves to receive packages and enables the weighing device 220 to detect the package weight.

[0030] Alternatively, the communication connection between the weighing device 220 and the control unit can be implemented as a wired communication connection or as a wireless communication connection.

[0031] In detail, the housing 100 is provided with an antenna 500, wherein the control unit establishes a communication connection with the Internet of Things via the antenna 500 and thereby establishes communication with the intelligent terminal, wherein the antenna 500 is preferably arranged at the upper part of the housing 100.

[0032] In this way, when a parcel is delivered through the delivery door 300, the parcel falls onto the support plate 210, the weighing device 220 detects an increase in weight, the weighing device 220 transmits a signal to the control unit, the control unit provides feedback to the Internet of Things, and the Internet of Things sends a message to the user about the storage of the parcel in the parcel box, whereby the user can learn in a timely manner via the intelligent terminal that a parcel has been delivered to the parcel box.When the user removes a parcel from the removal door 400, the weighing device 220 detects a weight reduction and transmits the signal to the control unit, which forwards the feedback to the Internet of Things, whereupon the Internet of Things transmits a message about the removal of the parcel from the parcel box to the user, so that the user can receive the information about the parcel removal via the intelligent terminal and confirm whether the parcel has been completely removed; for example, the parcel is considered completely removed when the weighing device no longer detects any weight.

[0033] Specifically, from a communication implementation perspective, the control unit and the smart terminal used by the user are each connected to the Internet of Things via wireless communication modules, thereby forming a data channel; the control unit transmits the status signals of the weighing device 220 to the cloud server of the Internet of Things and forwards them to the smart terminal to inform the user of the status of the parcel box in real time, wherein the specific communication transmission technologies correspond to the prior art and are not further described in the present application.

[0034] Thus, when using the parcel box with weighing feedback of the present application, through the real-time feedback of the weighing device 220, the user can efficiently know the parcel status inside the parcel box via the intelligent terminal, thereby preventing parcels from being forgotten or overlooked and greatly improving the user experience. The load-bearing mechanism also functions as the lower support component of the parcel box, thereby reducing the occupancy of the internal space of the parcel box and lowering the manufacturing and maintenance costs. The mounting case 230, in cooperation with the support structure 240, can also protect the weighing device 220 to prevent the weighing device 220 from being directly immersed in water in rainy weather.

[0035] Preferably, as in the Fig. 3, Fig. 4, Fig. As shown in Figure 5, a stabilizing element 250 is fixedly attached to the underside of the support plate 210. The stabilizing element 250 can be block-, rod-, or plate-shaped. As a detailed embodiment, the stabilizing element 250 is formed from a plurality of joined rod elements, wherein the rod elements run along the plate surface of the support plate 210. The stabilizing element 250 can increase the weight of the support plate 210, reduce the sway of the support plate 210, and increase the accuracy of package detection by the weighing device 220.

[0036] In particular, the weighing device 220 is designed as a bending beam sensor. The underside of the support plate 210 is firmly connected to the weighing device 220 via the stabilizing element 250. As shown in the Fig. 4 and Fig. 5, the stabilizing element 250 comprises a fastening rod 251, wherein the fastening rod 251 is fastened to one side of the top of the weighing device 220, and the other side of the weighing device 220 is arranged offset from the stabilizing element 250 in order to prevent the stabilizing element 250 from interfering with the function of the weighing device 220.

[0037] More precisely, as in Fig. 5, the underside of the side of the weighing device 220 that is offset from the stabilizing element 250 has a certain distance from the underside of the mounting housing 230, which distance also provides space for the proper operation of the weighing device 220.

[0038] In detail, the bending beam sensor used in this embodiment is a measuring device that utilizes the principle of bending deformation of a loaded bending beam and converts weight or force into an electrical signal using strain gauges. Due to its simple structure and high precision, the weighing device 220 can accurately detect weight changes even when light letters are received through the parcel box, thus notifying the user.

[0039] More specifically, there is a gap between the outer edge of the support plate 210 and the inner side wall of the housing 100 so that the support plate 210 can perform a slight movement for the weighing operation.

[0040] Preferably, the support structure 240 consists of several rod elements. As in Fig. 4, the support structure 240 comprises two longitudinal beams 241 and a plurality of cross beams 242, wherein the two longitudinal beams 241 are each fixedly connected to the two side walls of the housing 100, the cross beams 242 are arranged between the two longitudinal beams 241 and the mounting housing 230 is fixedly connected to the cross beams 242, wherein the support structure 240 causes the space below the support plate 210 to be connected to the outside space, which facilitates cleaning and ventilation.

[0041] As a comparison example: If the support structure 240 were to close the underside of the housing 100 by means of a plate, if water entered the bottom of the parcel box, the liquid could not be drained from the plate in time and would accumulate between the support plate 210 and the support structure 240, whereby the corresponding space would be difficult to clean and would promote corrosion.

[0042] As a specific embodiment, both the delivery door 300 and the removal door 400 are arranged on the front wall of the housing 100. The delivery door 300 is mounted so as to be rotatable about a horizontal axis and is thus designed to be openable and closable. The removal door 400 is mounted so as to be rotatable about a vertical axis and is thus designed to be openable and closable. In particular, the underside of the delivery door 300 is hingedly connected to the housing 100, and the left or right side of the removal door 400 is hingedly connected to the housing 100.

[0043] Preferably, as in Fig. 6, an anti-theft plate 600 is further included, wherein one side of the anti-theft plate 600 is hingedly connected to the inner wall of the housing 100, which is opposite the front wall of the housing 100, and the central part of the anti-theft plate 600 is hingedly connected to the central part of the delivery door 300 via a connecting rod 610.

[0044] As in Fig. As shown in Figure 7, the delivery door 300, when opened via the connecting rod 610, causes a rotational movement of the anti-theft plate 600, whereby the delivery door 300 and the anti-theft plate 600 overlap horizontally and together form an anti-theft surface on which the deliverer can place the parcel. As shown in Fig. 6, during the closing process, the delivery door 300 causes the anti-theft plate 600 to rotate via the connecting rod 610, whereby the anti-theft plate 600 returns to its starting position, the delivery door 300 and the anti-theft plate 600 move away from each other and the package falls due to gravity onto the upper side of the support plate 210 through the gap created between the delivery door 300 and the anti-theft plate 600.

[0045] This design enables effective protection of the parcels located in the lower area of ​​the parcel box when the delivery door 300 is open, thus preventing their theft. When the parcel is placed on the anti-theft surface, the anti-theft plate 600 and delivery door 300 components, which are connected to each other via the connecting rod 610, can support the parcel to a certain extent, thereby largely preventing the parcel box from closing abruptly and reducing security risks.

[0046] In particular, the delivery door 300 comprises, as shown in the Fig. 7 and Fig. 8, an outer door leaf 310, an inner wall plate 320, and an extension plate 330. The outer door leaf 310 is hingedly attached to the front wall of the housing 100, the inner wall plate 320 is fixed to the top and both side surfaces inside the outer door leaf 310, wherein the inner wall plate 320 and the outer door leaf 310 are arranged perpendicular to each other. The extension plate 330 is attached to the central part of the inner wall plate 320 and extends toward the bottom of the outer door leaf 310. The extension plate 330 projects downward beyond the outer door leaf 310 and thus forms an anti-theft surface together with the anti-theft plate 600. The inner wall plate 320 and the extension plate 330 together form a space for receiving packages, which prevents the packages from slipping out of the delivery door 300 when the delivery door 300 is opened.

[0047] Preferably, as in Fig. 8, the inner wall panels 320 are provided on both sides of the outer door leaf 310 with stop projections 321, which stop projections 321 protrude towards the inner side wall of the housing 100, wherein when the outer door leaf 310 is rotated up to a certain angle, the stop projections 321 can engage with the inner side wall of the housing 100 in order to limit the degree of opening of the outer door leaf 310, wherein this embodiment can also prevent excessive folding of the outer door leaf 310 and the consequent slipping of the package from the delivery door 300 when a package is present on the anti-theft surface.

[0048] To further meet the energy saving requirements, as in Fig. As shown in Figure 9, a solar panel 700 is arranged on the front wall of the housing 100. The solar panel 700 is arranged between the delivery door 300 and the removal door 400, i.e., the solar panel 700 is arranged vertically, thereby effectively preventing the accumulation of liquids and dust. The solar panel 700 is electrically connected to a battery, which is electrically coupled to the weighing device 220 and the control unit for power supply.

[0049] Preferably, as in Fig. As shown in Figure 9, the housing 100 is divided into a mailbox 110 and a parcel cabinet 120, wherein the mailbox 110 and the parcel cabinet 120 are separated from each other by a partition wall 130. The mailbox 110 is located above the parcel cabinet 120, wherein the volume of the mailbox 110 is smaller than the volume of the parcel cabinet 120, making it particularly suitable for storing thinner letters. The delivery door 300 and the removal door 400 are hingedly attached to the parcel cabinet 120, allowing larger parcels to be accommodated. This design can effectively adapt to user usage habits, with the mailbox 110 requiring little space and being located at a higher position in the parcel box, making it easier for users to remove and check for forgotten letters.

[0050] As in Fig.9, a letter removal door 111 is pivotally attached to the outer wall of the letter box 110, with a letter insertion door 112 being pivotally attached to the central part of the letter removal door 111, thereby further reducing the space requirement.

[0051] Preferably, the control unit is arranged inside the mailbox 110, thereby enabling the user to open the mailbox 110 from the top and thus to perform maintenance work on the control unit.

[0052] In this application, the terms "assembly," "arrangement," "provided with," "connection," "connected," and "attached" are to be understood in the broadest sense. For example, it may refer to a fixed connection, a detachable connection, or a one-piece construction; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection via an intermediate medium, or it may refer to an internal connection between two devices, elements, or components.
