A parcel locker

Abstract

This utility model relates to the field of logistics equipment technology, specifically disclosing a parcel locker. The locker includes a cabinet body, a parcel door, a gate, and a drive assembly. The cabinet body has a parcel opening and an internal storage cavity. The storage cavity includes a top plate located below the parcel opening, with an entrance communicating with the storage cavity on the top plate. The parcel door is pivotally connected to the cabinet body and has an open position (open parcel opening) and a closed position (closed parcel opening). The gate is slidably connected to the cabinet body or the top plate and has a working position (blocking the entrance) and a clearance position (opening the entrance). The gate in the working position receives items inserted through the parcel opening. The cabinet body also includes a blocking component. When the gate slides from the working position to the clearance position, the blocking component prevents items supported by the gate from moving with the gate, causing the items to detach from the gate and fall into the storage cavity through the entrance. The drive assembly drives the gate to move between the working position and the clearance position. Therefore, the parcel locker can both prevent theft and ensure sufficient storage capacity.

Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and in particular to a parcel locker. Background Technology

[0002] With the rapid development of the express delivery business, parcel lockers for self-service mailing are gradually being promoted and used in the market.

[0003] Parcel lockers consist of a drop-off slot and a locker box. The drop-off slot is located on top of the locker box, allowing users to deposit items with shipping labels attached into the locker. Since mailed items typically have a certain volume, the drop-off slot must be compatible with the largest possible size to ensure all items can be successfully placed into the locker. However, because parcel lockers are installed in public places, a large drop-off slot could pose a risk of items being stolen from the locker.

[0004] To address this, a parcel locker has been provided, comprising a locker body, a parcel box, a parcel door, a storage compartment, and a linkage mechanism. The parcel box is installed inside the locker body, with a parcel opening and an entrance at the top. The parcel door is movably connected to the locker body for opening and closing the parcel opening. The storage compartment is located inside the locker body and movably connected to it. The storage compartment is linked to the parcel door via the linkage mechanism. When the parcel door opens the parcel opening, the storage compartment faces the opening and closes the entrance. The storage compartment receives items inserted through the parcel opening and prevents theft of items from the parcel box through the opening or entrance. When the parcel door closes the parcel opening, the storage compartment rotates to empty the received items into the parcel box. This parcel locker can prevent theft of items from the parcel box through the parcel opening; however, the rotation of the storage compartment occupies storage space within the parcel box, reducing the locker's storage capacity. Utility Model Content

[0005] The purpose of this utility model is to provide a parcel locker that increases the storage capacity of the parcel locker while ensuring the safety of the items inside.

[0006] This utility model provides a parcel locker, which includes:

[0007] The cabinet has a parcel opening and a storage cavity inside. The storage cavity includes a top plate, which is located below the parcel opening in a vertical direction. The top plate has an entrance that communicates with the storage cavity.

[0008] The parcel door is pivotally connected to the cabinet body, and the parcel door can rotate relative to the cabinet body to have an open position where the parcel opening is open and a closed position where the parcel opening is closed;

[0009] A gate, slidably connected to the cabinet or the top plate, is slidable horizontally relative to the top plate to have a working position and a clearance position. When the gate is in the working position, the entrance is blocked by the gate, and the gate is used to receive items inserted through the mail inlet. When the gate is in the clearance position, the entrance is opened. The cabinet also includes a blocking member, which is located vertically above the gate. The blocking member is configured to prevent items supported by the gate from moving with the gate when the gate slides from the working position to the clearance position, so that the items detach from the gate and fall into the storage cavity through the entrance.

[0010] A drive assembly is connected to the gate drive, and the drive assembly is used to drive the gate to move to the working position and the avoidance position.

[0011] As a preferred technical solution for the parcel locker, the parcel door is pivotally connected to the locker body via a pivot shaft. The pivot shaft extends in the left-right direction and is located near the bottom of the parcel door. When the parcel door is flipped forward to the open position, the inner surface of the parcel door forms a support surface for supporting items.

[0012] As a preferred technical solution for the parcel locker, the parcel locker further includes a limiting post and a limiting member. The limiting post is fixedly connected to the locker body. The first end of the limiting member is hinged to the parcel door, and the second end of the limiting member is provided with a hook. When the parcel door is in the open position, the hook engages with the limiting post to limit the maximum opening angle of the parcel door. When the parcel door is in the closed position, the hook separates from the limiting post.

[0013] As a preferred technical solution for the parcel locker, the parcel locker also includes an elastic element. The first end of the elastic element is connected to the locker body, and the second end of the elastic element is connected to the second end of the limiting element. The elastic force of the elastic element causes the parcel door to always have a tendency to rotate toward the closed position.

[0014] As a preferred technical solution for the parcel locker, the blocking member includes a vertically extending baffle wall located above the gate. The gate includes a first end and a second end sequentially arranged along its own sliding direction from the working position to the avoidance position. When the gate is in the working position, the baffle wall is adjacent to or located at the second end of the gate. When the gate is in the avoidance position, the baffle wall is adjacent to or located at the first end of the gate. When the gate slides from the working position to the avoidance position, the baffle wall prevents items supported by the gate from moving with the gate, so that the items detach from the gate and fall into the storage cavity through the inlet.

[0015] As a preferred technical solution for the parcel locker, the locker body also includes two side panels that are spaced apart from each other in the left-right direction, and the two side panels are respectively connected to the left and right ends of the top plate at an angle.

[0016] The gate includes a door panel extending horizontally and two door side panels connected at an angle to the left and right ends of the door panel. The two door side panels are arranged opposite to the two side panels. When the gate is in the working position, the door panel closes the entrance and is used to receive items. Each door side panel is equipped with at least two rotatable first rollers. The axis of each first roller extends vertically, and the first roller on each door side panel rolls in cooperation with the corresponding side panel.

[0017] As a preferred technical solution for the parcel locker, the locker body also includes two height limit plates, which are respectively connected to the two side plates, and both height limit plates are arranged parallel to and at intervals with the top plate in the vertical direction.

[0018] Each of the door edge panels is also equipped with at least two rotatable second rollers, the axis of each second roller extends in the left and right direction, the two door edge panels are arranged in a one-to-one correspondence with the two height limit plates, the second roller on each door edge panel is located between the corresponding height limit plate and the top plate, and each second roller rolls in cooperation with the corresponding height limit plate and / or the top plate.

[0019] As a preferred technical solution for the parcel locker, the drive assembly is installed on the top plate. The drive assembly includes a motor and two transmission assemblies. The two transmission assemblies are spaced apart in the left-right direction and are respectively connected to the gate. The motor is simultaneously connected to the two transmission assemblies. The motor drives the gate to slide to the avoidance position and the working position through the two transmission assemblies.

[0020] As a preferred technical solution for the parcel locker, the parcel locker further includes a detection component for detecting the position of the gate. The detection component includes a first sensor and a second sensor, which are arranged at intervals along the sliding direction of the gate. The first sensor is used to detect whether the gate is located in the working position, and the second sensor is used to detect whether the gate is located in the avoidance position.

[0021] As a preferred technical solution for the parcel locker, the parcel locker further includes a parcel electronic lock and a parcel latch. The parcel electronic lock is installed on one of the locker body and the parcel door, and the parcel latch is installed on the other of the locker body and the parcel door. When the parcel door is in the closed position, the lock hook of the parcel electronic lock engages with the parcel latch to lock the parcel door in the closed position.

[0022] The parcel locker provided by this utility model has at least the following beneficial effects:

[0023] The locker includes a cabinet body, a locker door, a gate, and a drive assembly. The cabinet body has a locker opening and an interior storage cavity. The storage cavity includes a top plate, which is located vertically below the locker opening and has an entrance communicating with the storage cavity. The locker door is pivotally connected to the cabinet body and can rotate relative to the cabinet body to have an open position (open locker opening) and a closed position (closed locker opening). The gate is slidably connected to the cabinet body or the top plate and can slide horizontally relative to the top plate to have a working position and a clearance position. When in the working position, the entrance is blocked by a gate, which is used to receive items inserted through the mail slot. When the gate is in the clearance position, the entrance is opened. The cabinet also includes a blocking member, which is located above the gate in the vertical direction. The blocking member is configured to prevent items supported by the gate from moving with the gate when the gate slides from the working position to the clearance position, so that the items detach from the gate and fall into the storage cavity through the entrance. The drive assembly is drivenly connected to the gate and is used to drive the gate to move to the working position and the clearance position. The parcel locker provided in this embodiment, when a parcel needs to be sent, positions the gate in the working position and opens the parcel slot. At this time, the gate blocks the entrance, and items inserted through the parcel slot will fall onto the gate, preventing theft of items from the storage cavity. After delivery, the parcel door closes the parcel slot, and the drive assembly moves the gate to a clearance position, gradually opening the entrance. During this process, a blocking component prevents items on the gate from moving with it, causing the items to detach from the gate and fall into the storage cavity through the entrance. The gate of this parcel locker moves horizontally between the working and clearance positions, thus not occupying storage cavity space. The parcel locker provided by this invention both prevents theft and ensures sufficient storage capacity. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0054] Please refer to Figures 1 to 4 This embodiment provides a parcel locker, which includes a locker body 1, a parcel door 2, a gate 3, and a drive assembly 4. The locker body 1 has a parcel opening 12 and a storage cavity 11 inside. The storage cavity 11 includes a top plate 111, which is vertically positioned below the parcel opening 12 and has an inlet 112 communicating with the storage cavity 11. The parcel door 2 is pivotally connected to the locker body 1 and can rotate relative to the locker body 1 to have an open position (open parcel opening 12) and a closed position (closed parcel opening 12). The gate 3 is slidably connected to the locker body 1 or the top plate 111 and can slide horizontally relative to the top plate 111 to have a working position and a clearance position. When the gate 3 is in the working position (e.g., when the top plate 111 is closed), the gate 3 can slide horizontally relative to the top plate 111. Figure 2When (as shown), the entrance 112 is blocked by the gate 3, and the gate 3 is used to receive items inserted through the mail slot 12. When the gate 3 is in the clearance position (as shown), Figure 4 When the gate 3 is in the working position, the entrance 112 is opened; the cabinet 1 also includes a blocking member 13, which is located above the gate 3 in the vertical direction. The blocking member 13 is configured to block the items supported by the gate 3 from moving with the gate 3 when the gate 3 slides from the working position to the avoidance position, so that the items are removed from the gate 3 and fall into the storage cavity 11 through the entrance 112; the drive assembly 4 is connected to the gate 3 in a transmission manner, and the drive assembly 4 is used to drive the gate 3 to move to the working position and the avoidance position.

[0055] The parcel locker provided in this embodiment, when a parcel needs to be sent, positions the gate 3 in the working position and opens the parcel opening 12 with the parcel door 2. At this time, the gate 3 blocks the entrance 112, and items inserted through the parcel opening 12 will fall onto the gate 3, preventing theft of items from the storage cavity 11 through the parcel opening 12 and the entrance 112. After delivery, the parcel door 2 closes the parcel opening 12, and the drive assembly 4 drives the gate 3 to move to the clearance position, gradually opening the entrance 112. During this process, the blocking member 13 prevents items on the gate 3 from moving with the gate 3, causing the items to detach from the gate 3 and fall into the storage cavity 11 through the entrance 112. The gate 3 of this parcel locker moves horizontally between the working position and the clearance position, thus not occupying the space of the storage cavity 11. The parcel locker provided in this embodiment can both prevent theft and ensure the storage capacity of the parcel locker.

[0056] Alternatively, please refer to Figure 1 The parcel locker also includes at least one of the following components: a first camera 101, a touchscreen 102, a microphone assembly 103, a barcode scanner 104, a voucher outlet 105, and a packaging bag outlet 106, all installed on the locker body 1. This embodiment exemplifies a scheme where the parcel locker simultaneously includes the first camera 101, touchscreen 102, microphone assembly 103, barcode scanner 104, voucher outlet 105, and packaging bag outlet 106. The first camera 101 monitors the parcel locker's environment; the touchscreen 102 interacts with the user to facilitate parcel delivery; the microphone assembly 103 provides voice prompts; the barcode scanner 104 scans barcodes; the voucher outlet 105 outputs the transaction voucher; and the packaging bag outlet 106 outputs a packaging bag for users to pack their items.

[0057] Alternatively, please refer to Figure 2 , Figures 4 to 7The parcel locker also includes a parcel electronic lock 61 and a parcel latch 62. The parcel electronic lock 61 is installed on one of the locker body 1 and the parcel door 2, and the parcel latch 62 is installed on the other of the locker body 1 and the parcel door 2. When the parcel door 2 is in the closed position, the locking hook of the parcel electronic lock 61 engages with the parcel latch 62 to lock the parcel door 2 in the closed position. In this embodiment, an exemplary scheme is provided in which the parcel electronic lock 61 is installed on the locker body 1 and the parcel latch 62 is installed on the parcel door 2. With this configuration, when the parcel door 2 is in the closed position, the parcel electronic lock 61 and the parcel latch 62 work together to ensure the stability of the parcel door 2. Furthermore, when the gate 3 is in the avoidance position, it can prevent the parcel door 2 from being opened at will, thus preventing the theft of items in the storage cavity 11 through the parcel opening 12 and the entrance 112.

[0058] Optionally, the parcel lock 61 also includes a hook position detection sensor (not shown in the figures), and the parcel locker also includes a controller (not shown in the figures). The hook position detection sensor is used to detect whether the hook of the parcel lock 61 is in the position of engaging with the parcel latch 62. When the hook position detection sensor detects that the hook is in the position of engaging with the parcel latch 62, it indicates that the parcel door 2 is in the closed position. When it detects that the hook is disengaged from the parcel latch 62, it indicates that the parcel door 2 is in the open position. The controller is connected to the parcel lock 61 and the motor 41 of the drive assembly 4 (e.g., Figure 11 (As shown) Electrically connected, the controller is configured to control the motor 41 of the drive assembly 4 to operate based on the signal output by the hook position detection sensor. When the controller receives a signal from the hook position detection sensor indicating that the hook is engaged with the parcel latch 62 (i.e., the parcel door 2 is in the closed position), the controller controls the motor 41 of the drive assembly 4 to drive the gate 3 to move to the avoidance position. This configuration ensures that the gate 3 can only move from the working position to the avoidance position under the drive of the drive assembly 4 when the parcel door 2 is in the closed position, thus preventing the parcel opening 12 from connecting with the inlet 112 and protecting the items in the storage cavity 11.

[0059] Alternatively, please refer to Figures 1 to 3 The cabinet body 1 also has a retrieval port 14 on its side wall 15, which communicates with the storage cavity 11. The locker also includes a retrieval door 5 pivotally connected to the cabinet body 1. The retrieval door 5 is used to open and close the retrieval port 14. With this configuration, the courier can retrieve the items stored in the storage cavity 11 by opening the retrieval port 14 through the retrieval door 5.

[0060] Alternatively, please refer to Figure 3The parcel locker also includes a retrieval electronic lock 63 and a retrieval latch 64. The retrieval electronic lock 63 is installed on one of the locker body 1 and the retrieval door 5, and the retrieval latch 64 is installed on the other of the locker body 1 and the retrieval door 5. When the retrieval door 5 is in the closed retrieval opening 14 position, the locking hook of the retrieval electronic lock 63 engages with the retrieval latch 64 to lock the retrieval door 5 in the closed retrieval opening 14 position. In this embodiment, an exemplary configuration is provided where the retrieval electronic lock 63 is installed on the locker body 1 and the retrieval latch 64 is installed on the retrieval door 5. This configuration can prevent the retrieval door 5 from being opened arbitrarily, improving the security of items in the storage compartment 11.

[0061] Alternatively, please refer to Figure 4 The locker also includes a presence sensor installed on the locker body 1. The controller is electrically connected to the presence sensor. The presence sensor is configured to detect whether there is an item on the gate 3 in the working position. When there is an item on the gate 3 in the working position and the parcel door 2 is in the closed position, the controller controls the motor 41 of the drive assembly 4 to drive the gate 3 to move to the avoidance position so that the item on the gate 3 falls into the storage cavity 11. With this configuration, the presence sensor can detect whether there is an item on the gate 3. Only when there is an item on the gate 3 and the parcel door 2 is in the closed position will the drive assembly 4 drive the gate 3 to move to the avoidance position to prevent the parcel opening 12 and the inlet 112 from connecting, so as to protect the items in the storage cavity 11.

[0062] Alternatively, please continue to refer to Figure 4 In this embodiment, the presence sensor includes a second camera 71, which is used to acquire a first actual image of the gate 3 located at the working position. The controller determines whether there is an object on the gate 3 based on the first actual image. Specifically, the controller stores a first preset image in advance. The first preset image is an image of the gate 3 located at the working position when there is no object. The controller compares the first preset image with the first actual image. When the similarity between the first actual image and the first preset image is greater than or equal to a first set value, it is determined that there is no object on the gate 3; when the similarity between the first actual image and the first preset image is less than the first set value, it is determined that there is an object on the gate 3.

[0063] Optionally, the presence of sensors includes a first photoelectric sensor, which includes a first light emitter and a first light receiver, and the parcel locker includes two side walls 15 located on the left and right sides of the parcel opening 12 (see...). Figure 9The first light emitter and the first light receiver are respectively installed on two side walls 15 and arranged opposite each other. In the vertical direction, the first photoelectric sensor is installed above and adjacent to the gate 3 in the working position. When there is an object on the gate 3, the object blocks the first light receiver from receiving the light emitted by the first light emitter, and the first photoelectric sensor outputs a first signal. When there is no object on the gate 3, the first light receiver can receive the light emitted by the first light emitter, and the first photoelectric sensor outputs a second signal. The controller receives the signal and determines whether there is an object on the gate 3 based on the signal output by the first photoelectric sensor. Specifically, when the controller receives the first signal, it determines that there is an object on the gate 3, and when the controller receives the second signal, it determines that there is no object on the gate 3.

[0064] It should be noted that the presence sensor may include both the second camera 71 and the first photoelectric sensor, or it may include only the second camera 71, or only the first photoelectric sensor. When the presence sensor includes both the second camera 71 and the first photoelectric sensor, the presence of an item on the gate 3 is determined only when both conditions are met: the controller determines that an item exists on the gate 3 based on the first actual image acquired by the second camera 71, and the controller receives the first signal. If either condition is not met, the gate 3 is determined not to contain an item.

[0065] Alternatively, please continue to refer to Figure 4 The locker also includes a full detection sensor, which is installed below and adjacent to the top plate 111. The full detection sensor is used to detect whether the storage cavity 11 is full of items.

[0066] Alternatively, please continue to refer to Figure 4 In this embodiment, the fullness sensor includes a third camera 72, which is connected to the controller. The third camera 72 is used to acquire a second actual image of the storage cavity 11 and the area adjacent to the top plate 111. The controller determines whether the storage cavity 11 is full of items based on the second actual image. Specifically, the controller stores a second preset image in advance, which is an image of the storage cavity 11 when it is not full of items. The controller compares the second preset image with the second actual image. When the similarity between the second actual image and the second preset image is greater than or equal to a second set value, it is determined that the storage cavity 11 is not full of items; when the similarity between the second actual image and the second preset image is less than the second set value, it is determined that the storage cavity 11 is full of items.

[0067] As one alternative, the fullness sensor includes a second photoelectric sensor 75, which includes a second light emitter and a second light receiver. The second light emitter and the second light receiver are respectively installed on two opposing cavity walls of the storage cavity 11 in the left-right direction. In the vertical direction, the second photoelectric sensor 75 is located near the top plate 111. When the storage cavity 11 is full of items, the items block the second light receiver from receiving the light emitted by the second light emitter, and the second photoelectric sensor 75 outputs a third signal. When the storage cavity 11 is not full of items, the second light receiver can receive the light emitted by the second light emitter, and the second photoelectric sensor 75 outputs a fourth signal. The controller receives the signal and determines whether there are items on the gate 3 based on the signal output by the second photoelectric sensor 75. Specifically, when the controller receives the third signal, it determines that the storage cavity 11 is full of items; when the controller receives the fourth signal, it determines that the storage cavity 11 is not full of items.

[0068] It should be noted that the fullness sensor can include both the third camera 72 and the second photoelectric sensor 75, or it can include only the third camera 72, or only the second photoelectric sensor 75. When the fullness sensor includes both the third camera 72 and the second photoelectric sensor 75, the storage cavity 11 is only determined to be full when the controller determines that the storage cavity 11 is full based on the second actual image obtained by the third camera 72, and the controller receives a third signal. If either condition is not met, the storage cavity 11 is determined to be unfilled.

[0069] Alternatively, please continue to refer to Figure 4 The locker also includes a presence / absence sensor 76, which is installed in the storage cavity 11 and located near the bottom wall of the storage cavity 11. The presence / absence sensor 76 is used to detect whether there are items in the storage cavity 11.

[0070] Alternatively, please refer to Figure 5 The parcel locker also includes a detection component for detecting the position of the gate 3. The detection component includes a first sensor 73 and a second sensor 74, which are arranged at intervals along the sliding direction of the gate 3. The first sensor 73 is used to detect whether the gate 3 is in the working position, and the second sensor 74 is used to detect whether the gate 3 is in the avoidance position. This configuration allows for accurate detection of whether the gate 3 is in the working position or the avoidance position.

[0071] Alternatively, please refer to Figure 6 and Figure 7The controller is electrically connected to the first sensor 73 and the second sensor 74 respectively. The gate 3 slides in the front-back direction (as shown by arrow ab in the figure). The gate 3 includes a gate plate 31 and a door side plate 32 connected at an angle to the gate plate 31. The gate plate 31 is used to block the entrance 112. The door side plate 32 includes a front end and a rear end. When the gate 3 is in the closed position, the front end of the door side plate 32 cooperates with the first sensor 73 and triggers the first sensor 73 to output a first detection signal that the gate 3 is in the working position. When the gate 3 is in the avoidance position, the rear end of the door side plate 32 cooperates with the second sensor 74 and triggers the second sensor 74 to output a second detection signal that the gate 3 is in the avoidance position.

[0072] Specifically, the controller controls the motor 41 of the drive assembly 4 and the electronic lock 61 for parcel delivery to operate based on the signal output by the detection assembly. When parcel delivery is initiated, the controller first acquires the signal output by the first sensor 73. If the first sensor 73 does not output the first detection signal, the controller controls the motor 41 of the drive assembly 4 to drive the gate 3 to the working position until the first sensor 73 outputs the first detection signal. Then, the controller controls the electronic lock 61 for parcel delivery to unlock the parcel door 2. The item that the user puts in through the parcel delivery slot 12 will fall onto the gate 3. The controller acquires the signal output by the presence sensor. When the signal output by the presence sensor indicates that there is an item on the gate 3, the controller acquires the signal output by the hook position detection sensor. When the signal output by the hook position detection sensor indicates that the hook of the electronic lock 61 for parcel delivery is engaged with the parcel delivery latch 62, the drive assembly 4 drives the gate 3 to the clearance position until the second sensor 74 outputs the second detection signal, causing the item to detach from the gate 3 and fall into the storage cavity 11 from the entrance 112.

[0073] It should be noted that the first sensor 73, the second sensor 74, and the presence or absence of a sensor 76 can all be photoelectric sensors, and their working principle is similar to that of the first photoelectric sensor, so it will not be described in detail here.

[0074] Alternatively, please refer to Figure 4 , Figures 8 to 10The parcel door 2 is pivotally connected to the cabinet body 1 via a pivot shaft 23. The pivot shaft 23 extends in the left-right direction (as shown by arrow cd in the figure) and is located near the bottom of the parcel door 2. When the parcel door 2 is flipped forward to the open position, the inner surface of the parcel door 2 forms a support surface 211 for supporting items. With this configuration, when the parcel door 2 is rotated from the closed position to the open position, the parcel door 2 flips forward. When the parcel door 2 is in the open position, the inner surface of the parcel door 2 extends approximately horizontally, forming a support surface 211 for supporting items. At this time, the user can place items on the support surface 211 and then push the items into the cabinet body 1 through the parcel slot 12, moving the items to the gate 3 located in the working position for convenient delivery.

[0075] Alternatively, please refer to Figure 1 and Figure 3 The parcel door 2 is equipped with a handle 24, which allows the user to switch the parcel door 2 between the open and closed positions.

[0076] Alternatively, please refer to Figure 2 , Figures 8 to 11 The locker also includes a limiting post 81 and a limiting member 82. The limiting post 81 is fixedly connected to the locker body 1. The first end of the limiting member 82 is hinged to the locker door 2, and the second end of the limiting member 82 is provided with a hook 823. When the locker door 2 is in the open position, the hook 823 engages with the limiting post 81 to limit the maximum opening angle of the locker door 2. When the locker door 2 is in the closed position, the hook 823 separates from the limiting post 81. With this configuration, when the locker door 2 is in the open position, the engagement of the hook 823 with the limiting post 81 can limit the maximum opening angle of the locker door 2, and at the same time improve the positional stability of the locker door 2.

[0077] Alternatively, please refer to Figure 2 , Figure 9 and Figure 10 When the parcel gate 2 is in the open position, the angle between the parcel gate 2 and the gate 3 in the working position is α, and 90°<α≤180°. This arrangement allows the support surface 211 to not only support the item but also guide it into the parcel opening 12, making it easier to push the item through the parcel opening 12 onto the gate 3 in the working position.

[0078] Alternatively, please refer to Figure 2 , Figure 9 and Figure 11The parcel locker includes two limiting posts 81 and two limiting members 82. The two limiting posts 81 are respectively located on the left and right sides of the parcel opening 12. The first end of each of the two limiting members 82 is hinged to the parcel door 2. When the parcel door 2 is in the open position, the hooks 823 of the two limiting members 82 engage with the two limiting posts 81, allowing the parcel door 2 in the open position to reliably support heavier items. Optionally, the parcel door 2 is provided with a pivot (not shown in the figure) extending in the left-right direction. The first ends of the two limiting members 82 are sleeved on the pivot. When the parcel door 2 rotates between the open and closed positions, the two limiting members 82 rotate around the pivot.

[0079] Alternatively, please refer to Figure 10 and Figure 11 Under its own weight, the limiting member 82 always overlaps the limiting post 81. During the process of the mail door 2 rotating from the closed position to the open position, the limiting member 82 slides relative to the limiting post 81. When the mail door 2 rotates to the open position, the hook 823 located at the second end of the limiting member 82 engages with the limiting post 81. This design ensures a stable fit between the limiting member 82 and the limiting post 81.

[0080] Alternatively, please refer to Figure 9 and Figure 10 The mail door 2 includes an inner door 21 and an outer door 22 that are fastened together. The pivot is located between the inner door 21 and the outer door 22, and the support surface 211 is formed by the inner door 21.

[0081] Alternatively, please refer to Figures 8 to 11 The parcel locker also includes an elastic element 9. The first end of the elastic element 9 is connected to the locker body 1, and the second end of the elastic element 9 is connected to the second end of the limiting element 82. The elastic force of the elastic element 9 ensures that the parcel door 2 always tends to rotate towards the closed position. By setting the elastic element 9, the parcel door 2 can be more stable when in the closed position, and its support strength is higher when in the open position. Furthermore, when the parcel door 2 rotates to the open position, it can also buffer the force between the limiting element 82 and the limiting post 81. In addition, by ensuring that the second end of the limiting element 82 is always connected to the elastic element 9, the limiting element 82 will not be in a free state, thus avoiding accidents such as collisions between the limiting element 82 and other structures. Preferably, in this embodiment, the elastic element 9 is a tension spring; in other embodiments, the elastic element 9 can also be a compression spring.

[0082] Alternatively, please refer to Figure 11 The limiting member 82 includes two first plates 821 arranged relatively parallel and spaced apart, and a second plate 822 connected between the two first plates 821. The second ends of the two first plates 821 are provided with the hooks 823 mentioned above, and the second plate 822 is provided with hanging holes 824, on which the tension spring is hung.

[0083] Alternatively, please refer to Figure 10The blocking member 13 includes a baffle 131 extending vertically (as indicated by arrow ef in the figure). The baffle 131 is located above the gate 3. The gate 3 includes a first end and a second end sequentially arranged in a direction that allows it to slide from the working position to the avoidance position (as indicated by directions a to b in the figure). When the gate 3 is in the working position, the baffle 131 is adjacent to or located at the second end of the gate 3. When the gate 3 is in the avoidance position, the baffle 131 is adjacent to or located at the first end of the gate 3. When the gate 3 slides from the working position to the avoidance position, the baffle 131 prevents items supported by the gate 3 from moving with the gate 3, causing the items to detach from the gate 3 and fall into the storage cavity 11 through the inlet 112. This arrangement ensures that when the gate 3 moves from the working position to the avoidance position, the baffle 131 moves relative to the gate 3 from the second end to the first end, reliably pushing items on the gate 3 into the inlet 112, thereby causing the items to fall into the storage cavity 11.

[0084] Alternatively, please refer to Figure 9 and Figure 10 In this embodiment, the parcel slot 12 is located on the front wall of the cabinet 1. When the gate 3 slides from the working position to the avoidance position, the gate 3 slides from front to back. The cabinet 1 also includes two side walls 15 spaced apart in the left-right direction, and the first ends of the two side walls 15 are respectively connected to the left and right edges of the parcel slot 12. A baffle 131 is connected between the second ends of the two side walls 15 and spaced apart from the parcel slot 12 in the front-back direction. The baffle 131 and the two side walls 15 together form a... The temporary storage space 20 is connected to the mail outlet 12. When the gate 3 is in the working position, the temporary storage space 20 is disconnected from the entrance 112. Items sent from the mail outlet 12 to the gate 3 are restricted by the baffle 131 and the two side walls 15 and remain on the gate 3. When the gate 3 moves to the avoidance position, the temporary storage space 20 is connected to the entrance 112. The baffle 131 prevents the items on the gate 3 from moving with the gate 3, causing the items to leave the gate 3 and fall into the storage cavity 11 through the entrance 112.

[0085] As one alternative, the parcel slot 12 is located on the front wall of the cabinet 1. When the gate 3 slides from the working position to the avoidance position, the gate 3 slides from left to right or from right to left. The cabinet 1 also includes two side walls 15 connected at an angle. One of the two side walls 15 is spaced apart from the parcel slot 12 in the front-back direction. The other of the two side walls 15 is connected to one of the left and right edges of the parcel slot 12. The baffle 131 is connected to the other of the left and right edges of the parcel slot 12. The baffle 131 and the two side walls 15 together form a temporary storage space 20 that communicates with the parcel slot 12. When the gate 3 is in the working position, the temporary storage space 20 is disconnected from the entrance 112. When the gate 3 moves to the avoidance position, the temporary storage space 20 communicates with the entrance 112.

[0086] Alternatively, please refer to Figures 8 to 10 In this embodiment, the cabinet 1 also includes a top wall 16, which is connected to the top of the baffle 131 and the two side walls 15, and is vertically spaced from the entrance 112. When the gate 3 is in the working position, the gate 3, the baffle 131, the two side walls 15, and the top wall 16 form a temporary storage space 20 and a parcel delivery slot 12 connected to the temporary storage space 20. At this time, the temporary storage space 20 is disconnected from the entrance 112, so that items sent through the parcel delivery slot 12 can only land on the gate 3. Preferably, the parcel delivery electronic lock 61 is installed on the top wall 16.

[0087] Alternatively, please refer to Figures 6 to 10 The cabinet 1 also includes two side panels 17 spaced apart from each other in the left-right direction, and the two side panels 17 are connected to the left and right ends of the top plate 111 at an angle. This arrangement can enhance the structural strength of the top plate 111.

[0088] Alternatively, please refer to Figure 6 and Figure 12 The cabinet body 1 also includes two fixed plates 18, which are respectively connected to two side plates 17. Both fixed plates 18 are vertically parallel to and spaced apart from the top plate 111. Two side walls 15 are respectively connected to the two fixed plates 18 via fasteners. The parcel door 2 is rotatably connected to the two side plates 17 via a pivot shaft 23. This arrangement fully utilizes the space between the two fixed plates 18 and the top plate 111 to accommodate the gate 3, improving the compactness of the parcel locker structure.

[0089] Alternatively, please refer to Figures 6 to 10 The gate 3 includes a horizontally extending gate panel 31 and two side panels 32 connected at an angle to the left and right ends of the gate panel 31. The two side panels 32 are arranged opposite to the two side plates 17. When the gate 3 is in the working position, the gate panel 31 closes the entrance 112 and is used to receive items. Each side panel 32 is equipped with at least two rotatable first rollers 33, the axis of each first roller 33 extends vertically, and the first roller 33 on each side panel 32 rolls in engagement with the corresponding side plate 17. This arrangement allows the gate 3 to slide in the front-back direction between the working position and the avoidance position, while the two side plates 17 restrict the position of the gate 3 in the left-right direction; furthermore, when the gate 3 slides in the front-back direction between the working position and the avoidance position, the rolling engagement of the first rollers 33 with the side plates 17 reduces the resistance encountered by the gate 3 during movement. Preferably, a fixing frame 36 is installed on the door edge panel 32, and at least two first support shafts 35 are installed on the fixing frame 36. Each first support shaft 35 is fitted with a first roller 33, and the first roller 33 rotates relative to the fixing frame 36 through the corresponding first support shaft 35.

[0090] Optionally, the door panel 31 is provided with multiple sliding strips (not shown in the attached drawings), which are spaced apart in the left-right direction, and each sliding strip extends in the front-back direction and protrudes from the upper surface of the door panel 31; or, the door panel 31 is provided with multiple ball bearings (not shown in the attached drawings), each ball bearing partially protrudes from the upper surface of the door panel 31, and each ball bearing can roll freely around its own center; or, the door panel 31 is provided with multiple rollers (not shown in the attached drawings), which are spaced apart in the front-back direction, each roller bearing extends in the front-back direction and protrudes from the upper surface of the door panel 31, and each roller bearing can rotate freely around its own axis. By providing sliding strips, ball bearings, or rollers, the resistance when pushing items onto the door panel 31 and when items on the door panel 31 slide down through the inlet 112 can be reduced.

[0091] Alternatively, please refer to Figure 6 and Figure 15 The cabinet 1 also includes two height-limiting plates 19, which are connected to two side plates 17 respectively. Both height-limiting plates 19 are vertically opposite to and parallel to the top plate 111. Each door side plate 32 is also equipped with at least two rotatable second rollers 34, whose axes extend horizontally. The two door side plates 32 correspond one-to-one with the two height-limiting plates 19. Each second roller 34 on each door side plate 32 is located between the corresponding height-limiting plate 19 and the top plate 111, and each second roller 34 rolls in cooperation with the corresponding height-limiting plate 19 and / or top plate 111. This configuration, by setting the height-limiting plates 19 and the second rollers 34 located between the height-limiting plates 19 and the top plate 111, restricts the vertical position of the gate 3. When the gate 3 moves between the avoidance position and the working position, the rolling cooperation of the second rollers 34 with the height-limiting plates 19 and / or top plate 111 further reduces the resistance to movement of the gate 3. Preferably, the second roller 34 is rotatably engaged with the door edge panel 32 via the second support shaft 37.

[0092] Alternatively, please refer to Figures 12 to 15 The drive assembly 4 is mounted on the top plate 111. The drive assembly 4 includes a motor 41 and two transmission assemblies 42, which are spaced apart in the left-right direction. The two transmission assemblies 42 are respectively connected to the gate 3. The motor 41 is simultaneously connected to both transmission assemblies 42. The motor 41 drives the gate 3 to slide to the avoidance position and the working position through the two transmission assemblies 42. With this configuration, the motor 41 drives the gate 3 to slide through the two transmission assemblies 42, which makes the movement of the gate 3 more stable.

[0093] Alternatively, please continue to refer to Figure 2 , Figure 5 , Figures 8 to 10 ,and Figures 12 to 15In this embodiment, the transmission component 42 includes a linear motion component and a linear guide component. The linear motion component includes two pulleys 421 arranged at intervals along the front-back direction. One of the two pulleys 421 is connected to the motor 41 for transmission. The linear guide component includes a first synchronous belt 422 sleeved on the two pulleys 421 and supported by the two pulleys 421. The first synchronous belt 422 is also fixedly connected to the gate 3. When the motor 41 drives the pulleys 421 to rotate, the gate 3 is moved along the front-back direction through the first synchronous belt 422.

[0094] As an alternative, the linear guide may also include a lead screw that extends in the front-back direction and is connected to the motor 41 for transmission. The linear motion component includes a nut that is threaded to the lead screw and is fixedly connected to the gate 3. When the motor 41 drives the lead screw to rotate, the gate 3 is moved in the front-back direction through the nut. Alternatively, the linear guide may include a rack that extends in the front-back direction and is fixedly connected to the gate 3. The linear motion component includes a gear that meshes with the rack and is also connected to the motor 41 for transmission. When the motor 41 drives the gear to rotate, the gate 3 is moved in the front-back direction through the rack.

[0095] Alternatively, please continue to refer to Figure 2 , Figure 5 , Figures 8 to 10 ,and Figures 12 to 15 In this embodiment, the drive assembly 4 further includes a drive shaft 43, a drive wheel 44, and a second synchronous belt 45. The drive shaft 43 extends in the left-right direction. Each of the two transmission assemblies 42 has a pulley 421 fixedly sleeved on the drive shaft 43. The drive wheel 44 is also fixedly sleeved on the drive shaft 43. A motor pulley 411 is fixedly mounted on the output shaft of the motor 41. The second synchronous belt 45 is sleeved on the motor pulley 411 and the drive wheel 44 and supported by both. When the output shaft of the motor 41 rotates, the second synchronous belt 45 drives the drive shaft 43 to rotate. Simultaneously, the drive shaft 43 drives the pulleys 421 of the two transmission assemblies 42 to rotate, thereby causing the first synchronous belt 422 of the two transmission assemblies 42 to move, thus moving the gate 3 in the front-back direction. Preferably, along the axial direction of the drive shaft 43, the drive wheel 44 is located between the pulleys 421 of the two transmission assemblies 42.

[0096] It should be noted that when using synchronous belts, those skilled in the art can select the appropriate tensioning mechanism to adjust the tension of the synchronous belt according to actual needs, so as to ensure the reliability of the synchronous belt operation. This will not be elaborated here.

[0097] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
