Description

Technical Field

[0001] This application relates to the field of smart home technology, and more specifically, to a remotely controllable cabinet. Background Technology

[0002] With the booming development of e-commerce, the volume of express delivery services has experienced explosive growth. According to relevant statistics, my country's express delivery volume has continued to climb in recent years. Express delivery has become an indispensable part of people's daily lives, playing a vital role in everything from shopping and sending documents to other items. However, the last-mile delivery stage of express delivery faces numerous challenges.

[0003] Delivery drivers typically work during the morning and afternoon workdays, when many working people are unable to receive their packages at home. This forces drivers to make multiple deliveries or leave packages at security guards or property management offices, increasing the risk of lost, damaged, or misdelivered packages.

[0004] Special needs are difficult to meet. For express deliveries that require immediate or specific conditions of storage, such as fresh produce and fragile items (e.g., cold chain fresh produce must be signed for within 2 hours), existing collection methods cannot provide temperature control, drop protection, or other protective measures, resulting in a high rate of damage to goods. In addition, special groups such as elderly people living alone and people with disabilities have difficulty picking up their packages on their own due to mobility issues.

[0005] Although the widespread use of community public parcel lockers has alleviated the above problems to some extent, they still have limitations such as limited coverage (only covering large communities), high usage costs, and insufficient capacity, making it difficult to meet the personalized parcel delivery and receipt needs of family users for "privacy, convenience, and security".

[0006] To facilitate temporary storage of packages and allow users to send and receive packages at any time, we propose a remotely controllable locker. Utility Model Content

[0030] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0031] Please see Figure 1 This application provides a technical solution:

[0032] A remotely controllable cabinet includes a cabinet body 1, on which a first placement cavity 101 and a second placement cavity 102 are provided. A second cabinet door 4 is provided in the second placement cavity 102. The second cabinet door 4 is movably connected to the cabinet body 1 and is connected to the cabinet body 1 by an electronic lock 5. A circuit board is provided inside the first placement cavity 101. The circuit board integrates a control module and a communication module. The control module and the communication module are electrically connected, and the control module is electrically connected to the electronic lock 5.

[0033] The control module receives the on / off status of the electronic lock 5 and controls the electronic lock 5 to open. Users can interact with the communication module via external communication devices to obtain the on / off status of the electronic lock 5 and send opening commands. The control module receives the opening commands through the communication module and controls the electronic lock 5 to open, thus opening the second cabinet door 4. Users can control the second cabinet door 4 to open based on the courier's pickup time, facilitating the courier to retrieve or place packages into the second placement cavity 102. Based on the on / off status of the electronic lock 5, users can monitor the usage status of the parcel locker. Furthermore, a low-power control module is provided on the circuit board to set the control module, communication module, and / or electronic lock 5 to a low-power mode.

[0034] like Figure 4 As shown, the control module uses an STM32L051 chip processor. The input terminals of the STM32L051 chip processor are connected to the low-power control module to achieve low power consumption. The output terminals of the STM32L051 chip processor are connected to the communication module.

[0035] like Figure 5 As shown, the low-power control module is a human body pyroelectric infrared sensor, model BH9402. Its OUT pin is connected to the external interrupt pin of the control module. When someone enters the monitored area, the pyroelectric infrared sensing module IC1 of BH9402 is triggered, outputting a high level with a pulse width of 2-5s, and transistor Q1 is turned on. As long as the human body moves slightly within the module's monitoring area, IC1 continuously outputs a signal. This signal is input to the I / O terminal of the microcontroller IC3 of the control module. After being identified and judged by the microcontroller IC3 of the control module, a drive command signal is issued to drive the drive module IC4 of the electronic lock to perform the action.

[0036] The communication module uses the ESP8266 chip, a low-cost, low-power WiFi module. The processed data can be wirelessly transmitted to a remote terminal for display using the Modbus communication protocol.

[0037] Please see Figure 2 The first placement cavity 101 has a first cabinet door 2 at its opening. The first cabinet door 2 is rotatably connected to the cabinet body 1. The first cabinet door 2 and the cabinet body 1 are connected by a mechanical combination lock 3. The second cabinet door 4 is rotatably connected to the cabinet body 1. The electronic lock 5 includes a first housing 501, a lock hook 502, a first lock tongue 503, a lever 505, and a locking block 506. The first housing 501 is located in the second placement cavity 102 and is fixedly connected to the cabinet body 1. The first lock tongue 503 is fixedly connected to the second cabinet door 4. The first lock tongue 503 is rotatably connected to the first housing 501 through a rotating shaft and a coil spring. One end of the first lock tongue 503 is engaged with the lock hook 502 through a slot, and the other end is engaged with the locking block 506. The lever 505 is connected to the first housing 501 through a rotating shaft. One end of the lever 505 is connected to the locking block 506, and the other end extends to the outside of the first housing 501 and is fixedly connected to a pull rope 6. The free end of the pull rope 6 extends into the first placement cavity 101. The electronic lock 5 has a drive structure inside for driving the lever 505 to rotate. The drive structure is preferably an electromagnet 504. The electromagnet 504 is installed in the first housing 501 and connected to the lever 505.

[0038] When in use, the remotely controlled cabinet can place a battery in the first placement cavity 101 to power the circuit board. The circuit board is equipped with a voltage detection module that will alarm when the battery voltage is too low. When it is necessary to place an item into the second placement cavity 102, an electronic lock 5 opening command can be sent to the communication module through an external communication device. The control module receives the electronic lock 5 opening command through the communication module, powers the electromagnet 504, and uses the electromagnet 504 to rotate the lever 505, causing the locking block 506 to disengage from the first locking tongue 503. After the first locking tongue 503 loses the limit of the locking block 506, the locking hook 502 can be pulled outward to open the second cabinet door 4.

[0039] When the second cabinet door 4 is closed, the locking hook 502 is pushed to move towards the first locking tongue 503. The locking hook 502 pushes the first locking tongue 503 to rotate. The lower end of the first locking tongue 503 can slide on the upper surface of the locking block 506 and is finally limited by the locking block 506, fixing the locking hook 502 in the slot.

[0040] When the electronic lock 5 or the circuit board malfunctions and the second cabinet door 4 cannot be opened remotely, the user can open the first cabinet door 2 using the mechanical combination lock 3. By pulling the free end of the pull rope 6 in the first placement cavity 101, the lever 505 is driven to rotate, causing the locking block 506 to disengage from the first locking tongue 503. After the first locking tongue 503 loses the limit of the locking block 506, the lock hook 502 can be pulled outward to open the second cabinet door 4, thus realizing the function of opening the second cabinet door 4 even when the electronic lock 5 malfunctions.

[0041] like Figure 3 As shown, the mechanical combination lock 3 includes a second housing 301, a second latch 302, a bolt rod 303, a combination wheel 304, and a knob 305. The second housing 301 is installed and fixed to the first cabinet door 2. The knob 305 is rotatably connected to the second housing 301 and is fixedly connected to the second latch 302. The second latch 302 is engaged with the cabinet body 1. A gear is fixedly connected between the second latch 302 and the knob 305. The bolt rod 303 is slidably disposed inside the second housing 301 and is connected to the second housing 301 through an elastic element. The combination wheel 304 is rotatably sleeved on the outside of the bolt rod 303. A rack is fixedly connected to one end of the bolt rod 303, and the gear meshes with the rack.

[0042] When the combination wheel 304 is in the wrong position, the spline in the middle of the combination wheel 304 will limit the left and right movement of the bolt 303, and the knob 305 cannot be rotated; when the combination wheel 304 is in the correct position, the spline in the middle of the combination wheel 304 will move into the spline groove in the middle of the bolt 303, and the bolt 303 can slide relative to the combination wheel 304; the user can adjust the position of the second latch 302 by rotating the knob 305, move the second latch 302 out of the cabinet 1, and then open the first cabinet door 2.

[0043] Preferably, the height of the first placement cavity 101 is less than the height of the second placement cavity 102, and the first placement cavity 101 is located above the second placement cavity 102. There are at least two second placement cavities 102, and the electronic lock 5 of each second placement cavity 102 is independently electrically connected to the control module. The control module can control the operation of each individual electronic lock 5. This avoids the first placement cavity 101 being too large, resulting in wasted space, and by setting multiple second placement cavities 102, different items can be stored independently, increasing security.
