Description

Electric locks and lockers

[0001] This application claims priority to Chinese Patent Application No. 202411550947.X, filed with the Chinese Patent Office on November 1, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of storage device technology, such as an electronically controlled lock and a locker. Background Technology

[0003] Nowadays, lockers are used in a wider range of places, such as office buildings or residential areas to store express packages, supermarkets to store personal items, and tourist attractions or commercial streets to sell goods for self-service.

[0004] Storage lockers provided in related technologies typically include a cabinet body, a cabinet door, and an electronic lock. The cabinet body has an opening, and the cabinet door is pivotally connected to the cabinet body. The cabinet door is designed to be either open or closed. The electronic lock is installed in the cabinet body and includes a rotatable latch. A latch is provided on the cabinet door. When the cabinet door is closed, the latch engages with the latch to lock the door in place. For storage lockers placed outdoors, when outdoor temperatures drop below freezing, rainwater or snowmelt remaining between the cabinet door and body can easily freeze. To ensure the door can be opened normally, the storage lockers provided in related technologies also include an electric heating cable installed in the cabinet body and / or the cabinet door. When the cabinet door is closed, the electric heating cable surrounds the opening. When the user needs to open the door, the electric heating cable heats and melts the ice and snow frozen between the cabinet body and door, thus ensuring the door can be opened normally. However, electric heating cables themselves consume a lot of electricity during operation, and the heat generated is significantly lost due to heat transfer, resulting in low energy utilization. In addition, the melting process of ice and snow takes time, increasing the waiting time for users. Therefore, the storage cabinets in related technologies suffer from high energy consumption, low energy utilization, and low efficiency when melting ice and snow between the cabinet body and the cabinet door. Summary of the Invention

[0005] This application provides an electronically controlled lock and a locker that improves efficiency, reduces energy consumption, and enhances energy utilization when opening the locker door in the event of ice buildup between the locker body and the door.

The electric lock is installed on the other of the cabinet and the cabinet door.

[0012] Thirdly, this application provides another type of locker, which includes:

[0013] The cabinet has an open opening;

[0014] The cabinet door is movably connected to the cabinet body, and the cabinet door can move relative to the cabinet body to have an open position for opening the opening and a closed position for closing the opening;

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

[0039] Example 1

[0040] Referring to Figures 1 to 9, this embodiment provides a storage cabinet, which includes a cabinet body 50, a cabinet door 60, a mounting base 10, a latch 20, and an electric lock 30. The cabinet body 50 has an opening 503. The cabinet door 60 is movably connected to the cabinet body 50 and can move relative to the cabinet body 50, having an open position (opening the opening 503) and a closed position (closing the opening 503). The latch 20 is fixedly connected to the mounting base 10, which is installed on one of the cabinet body 50 and the cabinet door 60. The electric lock 30 is installed on the other of the cabinet body 50 and the cabinet door 60. When the cabinet door 60 is in the closed position, the electric lock 30 and the latch 20 engage to lock the position of the cabinet door 60.

[0041] When the locker is used outdoors, and the outdoor temperature drops below freezing, rainwater or snowmelt remaining between the locker door 60 and the locker body 50 can easily freeze between the locker door 60 and the locker body 50, causing the locker door 60 to be unable to open normally.

[0042] Referring to Figures 1 to 9, in this embodiment, the electronic lock 30 includes a housing 1, a locking hook 2, and an ice-breaking mechanism 3. The locking hook 2 is rotatably installed inside the housing 1, and the locking hook 2 can move relative to the housing 1 to have a locking position that engages with the latch 20 and an unlocking position that separates from the latch 20. The ice-breaking mechanism 3 is configured to break up the ice frozen between the cabinet door 60 and the cabinet body 50 so that the cabinet door 60 can be opened normally. The ice-breaking mechanism 3 includes a push rod 31 and a drive assembly 32. The push rod 31 is movably installed in the housing 1 and includes a force-receiving end 311 located inside the housing 1 and a force-applying end 312 extending outside the housing 1. The drive assembly 32 is configured to apply an impact force to the force-receiving end 311 of the push rod 31 so that the force-applying end 312 of the push rod 31 impacts the mounting base 10.

[0043] The electric lock 30 also includes a lock hook drive (not shown in the figure), which is connected to the lock hook 2 and is configured to drive the lock hook 2 to rotate to the locked position or the unlocked position.

[0044] The electronic lock 30 provided in this embodiment, when the cabinet door 60 is in the closed position, the lock hook 2 is in the locked position, and the lock hook 2 and the lock buckle 20 engage to lock the position of the cabinet door 60. When the door needs to be opened, the lock hook drive drives the lock hook 2 to rotate to the unlocked position. When the cabinet door 60 is affected by ice between the cabinet door 60 and the cabinet body 50, the drive assembly 32 applies an impact force to the force-bearing end 311 of the top rod 31, causing the force-applying end 312 of the top rod 31 to hit the mounting base 10, causing the cabinet body 50 or the cabinet door 60 connected to the mounting base 10 to vibrate, thereby breaking the ice frozen between the cabinet door 60 and the cabinet body 50, and the cabinet door 60 can be opened easily. The electronic lock 30 provided in this embodiment not only locks the position of the cabinet door 60, but also has an ice-breaking function. When installed on the storage cabinet, the ice frozen between the cabinet body 50 and the cabinet door 60 is broken by the impact of the ice-breaking mechanism 3, thereby achieving the purpose of ice breaking. Compared with melting ice by heating with an electric heating tape, the ice breaking efficiency is higher, and energy consumption can be reduced and energy utilization can be improved, while simplifying the structure of the storage cabinet.

[0045] In this embodiment, the housing 1 of the electronic lock 30 is fixedly connected to the cabinet 50, and the mounting base 10 is fixedly connected to the cabinet door 60. That is, the latch 20 is fixedly connected to the cabinet door 60 through the mounting base 10. The housing 1 is provided with a notch 13. When the cabinet door 60 is in the closed position, the latch 20 passes through the notch 13 and engages with the latch 2 located inside the housing 1. The housing 1 is also provided with a through hole 14. The force-applying end 312 of the push rod 31 passes through the through hole 14 and extends to the outside of the housing 1 to abut against the cabinet door 60. When the drive assembly 32 applies an impact force to the force-receiving end 311 of the push rod 31, the force-applying end 312 of the push rod 31 impacts the mounting base 10 installed on the cabinet door 60. Since the cabinet door 60 is movably connected to the cabinet 50, when the mounting base 10 is impacted, the cabinet door 60 is more likely to vibrate, which in turn makes it easier to break the ice frozen between the cabinet door 60 and the cabinet 50. In other embodiments, the housing 1 may be fixedly connected to the cabinet door 60, and the mounting base 10 may be fixedly connected to the cabinet body 50.

[0046] Optionally, the drive assembly 32 includes a drive member 321, which is configured to apply an impact force to the force-receiving end 311 of the push rod 31. In one embodiment, the drive member 321 includes an electrically operated telescopic rod 322 capable of reciprocatingly extending and retracting. The extension direction of the electrically operated telescopic rod 322 is the same as the movement direction of the push rod 31 extending out of the housing 1. When the electrically operated telescopic rod 322 extends, it abuts against the force-receiving end 311 of the push rod 31 and applies an impact force to the force-receiving end 311 of the push rod 31, so that the force-applying end 312 of the push rod 31 impacts the mounting base 10. Optionally, both the push rod 31 and the electric telescopic rod 322 move horizontally, and the force-applying end 312, the force-receiving end 311, and the electric telescopic rod 322 are arranged in sequence along the horizontal direction. This arrangement ensures that the thrust output by the electric telescopic rod 322 is applied to the force-receiving end 311 of the push rod 31 and then applied to the mounting base 10 through the force-applying end 312, resulting in a large impact force and higher ice-breaking efficiency.

[0047] Optionally, referring again to Figures 1 to 9, the drive assembly 32 further includes a transmission member 323, which is movably connected to the housing 1. When the transmission member 323 moves relative to the housing 1, it can abut or separate from the force-bearing end 311. The drive member 321 is configured to drive the transmission member 323 to move, and when the transmission member 323 abuts against the force-bearing end 311 of the push rod 31, it strikes the force-bearing end 311 of the push rod 31, thereby applying an impact force to the force-bearing end 311 of the push rod 31. By setting the transmission member 323, the positional relationship between the drive member 321 and the push rod 31 can be changed, reducing the size of the electric lock 30 along the movement direction of the push rod 31.

[0048] In one embodiment, the transmission member 323 is rotatably connected to the housing 1. The driving member 321 drives the transmission member 323 to rotate, causing the transmission member 323 to strike the force-receiving end 311 of the top rod 31. At this time, the torque output by the driving member 321 can be amplified by lever principle, increasing the impact force on the top rod 31 and making it easier to break the frozen ice. The transmission member 323 is rotatably mounted on the housing 1 via the first shaft 33. The driving member 321 is connected to the first end of the transmission member 323. The second end of the transmission member 323 strikes the force-receiving end 311 of the top rod 31. The first end and the second end of the transmission member 323 are located on both sides of the first shaft 33, and the distance between the first end of the transmission member 323 and the first shaft 33 is greater than the distance between the second end of the transmission member 323 and the first shaft 33. Therefore, under the premise that the output torque of the drive component 321 is constant, the impact force applied to the force-bearing end 311 of the top rod 31 is made greater by using the lever principle, so it is easier to break the ice frozen between the cabinet door 60 and the cabinet body 50.

[0049] In other embodiments, the transmission member 323 is slidably engaged with the housing 1, and the driving member 321 is configured to drive the transmission member 323 to slide, and cause the transmission member 323 to impact the force-receiving end 311 of the push rod 31 to apply an impact force to the force-receiving end 311 of the push rod 31. This arrangement facilitates the arrangement of the driving assembly 32 in the housing 1; or, the driving assembly 32 includes the driving member 321 and the transmission assembly, with the transmission assembly drivingly connected between the driving member 321 and the push rod 31. The driving member 321 drives the push rod 31 to slide through the transmission assembly, wherein the driving member 321 can be a motor, and the transmission assembly can be a gear and rack assembly; or, the driving assembly 32 includes a power source, which is directly connected to the push rod 31 and drives the push rod 31 to slide relative to the housing 1, wherein the power source is such as a cylinder, electric cylinder, etc.

[0050] Optionally, referring again to Figures 1 to 9, the drive assembly 32 further includes a first elastic element 328 connected to the transmission member 323. The first elastic element 328 is configured to ensure that the transmission member 323 always has a tendency to separate from the force-bearing end 311. The drive member 321 includes an electric telescopic rod 322 that can reciprocately extend and retract. When the electric telescopic rod 322 extends, it drives the transmission member 323 to move and causes the transmission member 323 to strike the force-bearing end 311 of the top rod 31. When the electric telescopic rod 322 retracts, the transmission member 323 rotates in the opposite direction under the action of the first elastic element 328 and separates from the force-bearing end 311 of the top rod 31. With this configuration, the electric telescopic rod 322 extends to drive the transmission component 323 to abut against the force-bearing end 311 of the top rod 31 and apply impact force, thereby striking the force-bearing end 311 of the top rod 31. When the electric telescopic rod 322 retracts, the first elastic element 328 causes the transmission component 323 to rotate in the opposite direction and separate from the force-bearing end 311 of the top rod 31. By repeatedly extending and retracting the electric telescopic rod 322, the force-bearing end 311 of the top rod 31 is repeatedly struck, thereby causing the force-applying end 312 of the top rod 31 to repeatedly impact the mounting base 10, which can break the ice more quickly and reliably.

[0051] It should be noted that when the electric telescopic rod 322 retracts, under the action of the first elastic element 328, the transmission element 323 can move to a certain distance from the force-bearing end 311 of the top rod 31. When the electric telescopic rod 322 extends again, it can drive the transmission element 323 to move synchronously a certain distance. During this period, the rotational speed of the transmission element 323 will be increased. When the transmission element 323 strikes the force-bearing end 311 of the top rod 31 under the push of the electric telescopic rod 322, the speed of the transmission element 323 drops instantly, generating a greater impact force to improve the ice-breaking effect. In addition, by driving the transmission element 323 to strike the top rod 31 together with the electric telescopic rod 322, the force of the electric telescopic rod 322 can also be transmitted to the force-bearing end 311 of the top rod 31 through the transmission element 323, making the vibration generated by the mounting base 10 greater, thereby further improving the ice-breaking effect.

[0052] Referring to Figures 3 to 6, in this embodiment, the driving component 321 can be an electric actuator, and correspondingly, the electric telescopic rod 322 is the push rod of the electric actuator; or, as shown in Figures 7 to 9, the driving component 321 can also be an electromagnet, and correspondingly, the electric telescopic rod 322 is the armature of the electromagnet.

[0053] In this embodiment, the transmission component 323 is rotatably connected to the housing 1 via the first shaft 33, and the first elastic component 328 is a torsion spring, which is sleeved on the first shaft 33. The two torsion arms of the torsion spring are respectively connected to the housing 1 and the transmission component 323. In other embodiments, the first elastic component 328 may also be a tension spring or a compression spring, etc.

[0054] Optionally, referring again to Figures 3 to 6, the transmission component 323 includes a transmission component body 324 rotatably connected to the housing 1, and a drive unit 325 fixedly connected to the transmission component body 324. The electric telescopic rod 322 and the top rod 31 are located on both sides of the drive unit 325. When the electric telescopic rod 322 extends, it pushes the drive unit 325 to strike the force-receiving end 311 of the top rod 31, and the drive unit 325 drives the transmission component body 324 to rotate. With this configuration, when the electric telescopic rod 322 pushes the drive unit 325, the force exerted when the electric telescopic rod 322 extends is directly applied to the drive unit 325. The force loss when the electric telescopic rod 322 extends is small, allowing the drive unit 325 to strike the force-receiving end 311 of the top rod 31 with a larger force, thereby ensuring that the impact force of the top rod 31 is greater and the cabinet door 60 is opened more reliably.

[0055] Optionally, as shown in Figures 3 to 6, in this embodiment, the transmission component body 324 is rotatably mounted on the housing 1 via the first shaft 33, allowing the transmission component 323 to rotate around the first shaft 33. The contact point between the electric telescopic rod 322 and the drive unit 325, and the contact point between the drive unit 325 and the force-receiving end 311 of the push rod 31, are located on the same side of the first shaft 33. Furthermore, the distance between the contact point between the electric telescopic rod 322 and the drive unit 325 and the first shaft 33 is less than the distance between the contact point between the drive unit 325 and the push rod 31 and the first shaft 33. This arrangement allows the drive unit 325 to have a larger stroke before striking the force-receiving end 311 of the push rod 31. Within this stroke, the drive unit 325, driven by the drive component 321, increases its rotational speed, resulting in a greater impact force on the push rod 31 upon impact.

[0056] Optionally, the angle between the extension / retraction direction of the electric telescopic rod 322 and the sliding direction of the top rod 31 is less than or equal to 5°. In other embodiments, the angle between the extension / retraction direction of the electric telescopic rod 322 and the sliding direction of the top rod 31 can also be set as needed.

[0057] Optionally, referring to Figures 3 to 9, in this embodiment, the driving part 325 is in the shape of a long rod. The first end of the driving part 325 is fixedly connected to the transmission body 324, and the first end of the driving part 325 is close to the first shaft 33. The second end of the driving part 325 is far away from the first shaft 33. The second end of the driving part 325 is set as the force-receiving end 311 for striking the top rod 31.

[0058] Optionally, referring to Figure 3, the transmission member 323 can rotate relative to the housing 1 to have a stop position. When the transmission member 323 is in the stop position, the transmission member 323 cooperates with the locking hook 2 in the locking position. The transmission member 323 prevents the locking hook 2 in the locking position from rotating to the unlock position, and the transmission member 323 is separated from the force-receiving end 311 of the push rod 31. Referring to Figure 4, when the transmission member 323 is out of the stop position, the transmission member 323 is separated from the locking hook 2, the locking hook 2 can rotate to the unlock position, and the transmission member 323 can strike the force-receiving end 311 of the push rod 31. The driving member 321 is also configured to drive the transmission member 323 to rotate from the stop position to the direction of disengaging from the stop position. After the transmission member 323 is out of the stop position, the driving member 321 is configured to drive the transmission member 323 to strike the force-receiving end 311 of the push rod 31, so that the force-applying end 312 of the push rod 31 impacts the mounting base 10. This configuration, when the hook 2 is in the locked position, prevents it from rotating to the unlocked position via the transmission component 323, thus locking the hook 2 and enhancing the safety performance of the electric lock 30. Simultaneously, the drive component 321 drives the transmission component 323 out of the stop position to unlock the hook 2. Thus, through the cooperation of the drive component 321 and the transmission component 323, the top rod 31 can be struck to de-ice the mounting base 10, and the hook 2 can also be unlocked. In other words, the drive component 321 also functions as a hook drive component. In this embodiment, both the drive component 321 and the transmission component 323 in the electric lock 30 serve dual purposes, simplifying the structure of the electric lock 30, reducing its cost, and improving its reliability. Furthermore, by integrating the ice-breaking mechanism 3 into the housing 1 of the electric lock 30, the impact force of the top rod 31 on the cabinet door 60 under the impact of the drive component 32 is greater, making it easier to open the cabinet door 60 when it is frozen to the cabinet body 50.

[0059] It should be noted that in this embodiment, the driving member 321 drives the transmission member 323 out of the stop position before striking the force-bearing end 311 of the top rod 31. When there is no ice between the cabinet door 60 and the cabinet body 50, the impact of the top rod 31 on the mounting base 10 can automatically open the cabinet door 60, making the opening operation simpler. The stop position can be a position point of the transmission member 323 or a position range of the transmission member 323. In this embodiment, the stop position is a position range of the transmission member 323. Under the action of the first elastic member 328, the transmission member 323 always has a tendency to rotate towards the stop position.

[0060] Optionally, when the driving member 321 drives the transmission member 323 to rotate from the stopped position to the direction of disengaging from the stopped position, the height of the center of gravity of the transmission member 323 gradually decreases. With this configuration, under the action of its own weight, the transmission member 323 tends to rotate in the direction of disengaging from the stopped position. Therefore, during the process of the driving member 321 driving the transmission member 323 to rotate from the stopped position to the direction of disengaging from the stopped position, the weight of the transmission member 323 does positive work on the transmission member 323, which helps to increase the rotational speed of the transmission member 323, thereby increasing the impact force applied by the transmission member 323 to the force-bearing end 311 of the push rod 31, thus improving the ice-breaking effect.

[0061] Optionally, referring to Figures 3 to 9, the locking hook 2 includes a locking groove 211 and a force-receiving part 22. The transmission member 323 also includes an abutment part 326. When the locking hook 2 is in the locked position and the transmission member 323 is in the stopped position, the locking groove 211 is configured to engage with the latch 20, and the abutment part 326 abuts against the force-receiving part 22 and prevents the locking groove 211 from separating from the latch 20. When the transmission member 323 is disengaged from the stopped position, the abutment part 326 separates from the force-receiving part 22, allowing the locking groove 211 to separate from the latch 20, and the drive part 325 can strike the force-receiving end 311 of the push rod 31. With this configuration, when the locking hook 2 is in the locked position and the transmission member 323 is in the stopped position, the transmission member 323 and the locking hook 2 cooperate with the force-receiving part 22 through the abutment part 326 to prevent the locking hook 2 from rotating to the unlocked position, thereby locking the position of the locking hook 2.

[0062] The lock hook 2 also includes a lock hook body 21, a lock groove 211 formed in the lock hook body 21, a force-bearing part 22 fixedly connected to the lock hook body 21, and a second shaft 35 fixed inside the housing 1. The lock hook body 21 is sleeved on the second shaft 35 and can rotate around the axis of the second shaft 35, so that the lock hook 2 can rotate between the locked position and the unlocked position around the axis of the second shaft 35. When the lock hook 2 is in the locked position, the latch 20 is located in the lock groove 211, and the extension direction of the lock groove 211 is the same as the opening direction of the cabinet door 60. The lock groove 211 is perpendicular to the door, so the lock latch 20 is prevented from moving and the cabinet door 60 cannot be opened. When the lock hook 2 is rotated to the unlock position, the opening of the lock groove 211 is connected to the notch 13 on the housing 1. The lock latch 20 located in the lock groove 211 will exit through the opening of the lock groove 211 and the notch 13, thereby opening the cabinet door 60. The abutment part 326 and the drive part 325 are both fixedly connected to the transmission body 324, and the line connecting the two to the rotation center of the transmission body 324 is set at an angle.

[0063] Optionally, referring to Figures 3 to 9, the electric lock 30 further includes a hook spring 34 connected to the hook 2. The elastic force of the hook spring 34 causes the hook 2 to always tend to rotate toward the unlocked position. Alternatively, the electric lock 30 also includes a tension spring connected between the hook 2 and the transmission member 323. The elastic force of the tension spring causes the hook 2 to always tend to rotate toward the unlocked position and causes the transmission member 323 to always tend to rotate toward the stopped position. By setting a hook spring 34, which cooperates with the first elastic element 328, when the door is not closed and there is no other external force, the hook 2 is in the unlocked position, and the hook 2 pushes against the transmission element 323, causing the transmission element 323 to be in the disengaged position. When the door is closed, the latch 20 enters the lock groove 211 of the hook 2 and drives the hook 2 to rotate from the unlocked position to the locked position. The hook 2 and the transmission element 323 rotate relative to each other. When the hook 2 rotates to the locked position, the hook 2 disengages from the transmission element 323, and the transmission element 323 rotates to the stop position under the action of the first elastic element 328, locking the position of the hook 2, which can enhance the safety performance of the electric lock 30. Optionally, the hook spring 34 is a torsion spring, and in other embodiments, it can also be replaced by a tension spring or a compression spring.

[0064] Optionally, the force-receiving part 22 has a concave arc-shaped structure, the center of which coincides with the axis of the first shaft 33, and the abutment part 326 has a convex arc-shaped structure, the center of which also coincides with the axis of the first shaft 33. When the locking hook 2 is in the locked position and the transmission member 323 is in the stopped position, the arc surface of the force-receiving part 22 and the arc surface of the abutment part 326 at least partially overlap, and under the action of the locking hook spring 34, the two abut together. The abutment part 326 can restrict the rotation of the force-receiving part 22, thereby preventing the locking groove 211 from separating from the lock 20.

[0065] Optionally, referring to Figures 3 to 9, the transmission component 323 also includes an emergency lever 327. One end of the emergency lever 327 is fixedly connected to the transmission component body 324, and the other end extends to the outside of the housing 1 and to the top of the storage cabinet via a connecting rod. When the drive component 321 cannot work due to power failure or other reasons, the emergency lever 327 can be moved by manually pulling the connecting rod. The emergency lever 327 drives the transmission component 323 to rotate, so that the drive part 325 of the transmission component 323 strikes the force-bearing end 311 of the top rod 31, thereby breaking the ice. Moreover, when the transmission component 323 strikes the force-bearing end 311 of the top rod 31, the lock hook 2 is unlocked and can rotate to the unlocked position under the action of the lock hook spring 34, so the cabinet door 60 can be opened.

[0066] Optionally, referring to Figures 3 through 9, the lines connecting the abutment portion 326, the drive portion 325, and the emergency lever 327 to the rotation center of the transmission body 324 are arranged in a Y-shape. The abutment portion 326, the drive portion 325, and the emergency lever 327 divide the space inside the housing 1 into three parts. The locking hook 2 and the push rod 31 are both located between the abutment portion 326 and the drive portion 325, and the drive member 321 is located between the emergency lever 327 and the drive portion 325. This arrangement makes the structure of the electric lock more compact.

[0067] Optionally, the ice-breaking mechanism 3 also includes a second elastic element 37, which is connected to the top rod 31 and is configured to make the top rod 31 always tend to move in the direction extending out of the housing 1. When the cabinet door 600 is in the closed position, the force-applying end 312 of the top rod 31 abuts against the mounting base 10. By providing a second elastic element 37, when ice forms between the cabinet door 60 and the cabinet body 50, the second elastic element 37 can also provide power to the top rod 31, thereby increasing the impact force of the force-applying end 312 of the top rod 31 on the mounting base 10 and further improving the ice-breaking effect. Additionally, when the drive assembly 32 impacts the force-receiving end 311 of the top rod 31, breaking the ice frozen between the cabinet door 60 and the cabinet body 50, the combined action of the impact force of the drive assembly 32 and the elastic force of the second elastic element 37 causes the top rod 31 to push open the cabinet door 60, increasing the force of the top rod 31 when opening the door, allowing the cabinet door 60 to automatically open to a larger angle, making it easier for the user to open the cabinet door 60. Optionally, the second elastic element 37 is a compression spring, and the second elastic element 37 is sleeved on the top rod 31. In other embodiments, the second elastic element 37 can also be a tension spring.

[0068] Optionally, referring to Figures 2 to 9, the push rod 31 is slidably connected to the housing 1. The housing 1 includes a side wall 11 and a support wall 12, which are parallel and spaced apart from the side wall 11. The push rod 31 is inserted into both the side wall 11 and the support wall 12. A limiting member 36 is provided on the push rod 31, located between the side wall 11 and the support wall 12. A second elastic member 37 is sleeved on the push rod 31 and located between the limiting member 36 and the support wall 12. The second elastic member 37 ensures that the push rod 31 always has a tendency to slide outward from the housing 1. Optionally, the limiting member 36 is a retaining ring, which is engaged with the push rod 31. When the push rod 31 slides, the limiting member 36 restricts the position of the push rod 31, preventing the push rod 31 from disengaging from the side wall 11 and the support wall 12.

[0069] In other embodiments, the top rod 31 is rotatably connected to the housing 1. The top rod 31 is arc-shaped and has an arc-shaped limiting groove. The housing 1 has a limiting post, which is inserted into the limiting groove to limit the rotation range of the top rod 31. The rotation center of the top rod 31 is concentric with the rotation center of the transmission member 323, and the force-bearing end 311 of the top rod 31 is located on the rotation path of the driving part 325 of the transmission member 323. When the driving member 321 drives the transmission member 323 to rotate, the driving part 325 of the transmission member 323 strikes the force-bearing end 311 of the top rod 31, so that the force-applying end 312 of the top rod 31 impacts the mounting base 10. After the ice is broken, the top rod 31, under the combined action of the impact force of the driving component 32 and the elastic force of the second elastic member 37, turns outward from the housing 1, so that the top rod 31 pushes open the cabinet door 60.

[0070] Optionally, referring to Figures 3 through 9, the top rod 31 can move relative to the housing 1, having an extended position and a retracted position. When the cabinet door 60 is in the closed position, the mounting base 10 abuts against the force-applying end 312 of the top rod 31, and the force-applying end 312 of the top rod 31 extends out of the side wall 11 by a first distance, placing the top rod 31 in the retracted position. When the cabinet door 60 is in the open position, the force-applying end 312 of the top rod 31 extends out of the side wall 11 by a second distance, placing the top rod 31 in the extended position, where the second distance is greater than the first distance. The storage cabinet also includes a controller (not shown in the figures). The electric lock 30 also includes a sensor 40. The controller is electrically connected to the sensor 40 and the drive unit 321. The sensor 40 is set to detect the position of the top rod 31. When the cabinet door 60 needs to be opened, the controller executes the command to unlock the lock hook 2 and periodically detects the detection signal output by the sensor 40. When the sensor 40 outputs a detection signal that the top rod 31 is in the retracted position, the controller also controls the drive unit 32 to intermittently strike the force-bearing end 311 of the top rod 31 a predetermined number of times until the sensor 40 outputs a detection signal that the top rod 31 is in the extended position.

[0071] In this embodiment, the controller's instruction to unlock the hook 2 includes controlling the drive member 321 to drive the transmission member 323 to rotate away from the stop position, thereby unlocking the hook 2. At this time, the hook 2 can turn to the unlock position. In other embodiments, when the hook drive member is connected to the hook 2 and configured to drive the hook to rotate to the unlock or lock position, the controller's instruction to unlock the hook 2 includes controlling the hook drive member to drive the hook 2 to rotate towards the unlock position.

[0072] With this setup, when cabinet door 60 needs to be opened, the controller first executes the command to unlock the latch 2 and periodically checks the detection signal output by sensor 40. If the push rod 31 is in the retracted position, it indicates that cabinet door 60 is still in the closed position, and the ice between cabinet door 60 and cabinet body 50 has not yet been broken. The controller controls the drive component 32 to intermittently strike the force-bearing end 311 of push rod 31 a predetermined number of times to perform the ice-breaking operation. If push rod 31 is in the extended position, it indicates that cabinet door 60 has already been opened, and no further ice-breaking operation is needed. Therefore, the controller stops controlling the drive component 32 to intermittently strike the force-bearing end 311 of push rod 31. The predetermined number of strikes can be set according to actual needs, such as three times, five times, etc., and is not limited here.

[0073] Optionally, sensor 40 cooperates with either transmission member 323 or top rod 31 to detect the position of top rod 31. This embodiment exemplifies a scheme where sensor 40 cooperates with transmission member 323. Sensor 40 can cooperate with or disengage from the drive part 325 of transmission member 323. When transmission member 323 strikes top rod 31 and drives top rod 31 to the extended position, drive part 325 of transmission member 323 cooperates with sensor 40, triggering sensor 40 to output a first signal, indicating that top rod 31 has moved to the extended position and cabinet door 60 is in the open position. When transmission member 323 strikes top rod 31 but top rod 31 is still in the retracted position, drive part 325 of transmission member 323 disengages from sensor 40, and sensor 40 outputs a second signal, indicating that top rod 31 is still in the retracted position and cabinet door 60 is still in the closed position. Therefore, within a predetermined time after the controller executes command 2 to unlock the locking hook, when the controller detects that sensor 40 outputs a second signal, the controller controls the drive assembly 32 to intermittently strike the push rod 31 a predetermined number of times; when the controller detects that the output signal of sensor 40 changes from the second signal to the first signal, the controller controls the drive assembly 32 to stop striking the push rod 31. Optionally, sensor 40 is a micro switch or a photoelectric sensor.

[0074] The electronically controlled lock 30 provided in this embodiment is configured to cooperate with a latch 20 fixed to the mounting base 10. The electronically controlled lock 30 includes a housing 1, a latch 2, and an ice-breaking mechanism 3. The latch 2 is rotatably installed in the housing 1 and can move relative to the housing 1 to have a locking position that engages with the latch 20 and an unlocking position that is separated from the latch. The ice-breaking mechanism 3 includes a push rod 31 and a drive assembly 32. The push rod 31 is movably installed in the housing 1 and includes a force-receiving end 311 located in the housing 1 and a force-applying end 312 extending out of the housing 1. The drive assembly 32 is configured to apply an impact force to the force-receiving end 311 of the push rod 31 so that the force-applying end 312 of the push rod 31 impacts the mounting base 10. When the electronic lock 20 provided in this embodiment is used on a locker, the electronic lock 30 is installed on one of the locker body 50 and the locker door 60, and the mounting base 10 is installed on the other of the locker body 50 and the locker door 60. When the locker door 60 is in the closed position, the lock hook 2 is in the locked position, and the lock hook 2 engages with the lock buckle 20 to lock the position of the locker door 60. If the locker door 60 is affected by ice between the locker door 60 and the locker body 50, thus hindering the opening of the locker door 60, the drive assembly 32 pushes the top rod. The force-bearing end 311 of the top rod 31 applies an impact force, causing the force-applying end 32 of the top rod 31 to strike the mounting base 10, causing the cabinet 50 or cabinet door 60 connected to the mounting base 10 to vibrate, thereby breaking the ice frozen between the cabinet door 60 and the cabinet 50, thus making it easy to open the cabinet door 60; the electric lock 30 provided in this embodiment also has an ice-breaking function, and the ice-breaking efficiency is higher than that of melting ice by heating with an electric heating tape, which can reduce energy consumption and improve energy utilization.

[0075] The locker provided in this application embodiment includes the aforementioned electronically controlled lock 30. The electronically controlled lock 30 breaks ice by impact, which is more efficient than melting ice by heating with an electric heating cable, and can reduce energy consumption and improve energy utilization.

[0076] Example 2

[0077] Please refer to Figures 10 to 12. This embodiment provides a storage cabinet, which includes a cabinet body 50, a cabinet door 60, a lock (not shown in the figures), and an ice-breaking mechanism 3. The cabinet 50 has an opening; the cabinet door 60 is movably connected to the cabinet 50, and the cabinet door 60 can move relative to the cabinet 50 to have an open position for opening the opening and a closed position for closing the opening; a lock is installed on the cabinet 50 or the cabinet door 60, and when the cabinet door 60 is in the closed position, the lock is set to lock the position of the cabinet door 60. The lock can be an electromagnetic lock or a motor lock; the ice-breaking mechanism 3 includes a top rod 31 and a drive assembly 32. The top rod 31 is movably installed on one of the cabinet 50 and the cabinet door 60. The top rod 31 includes a force-receiving end 311 and a force-applying end 312. The drive assembly 32 is configured to apply an impact force to the force-receiving end 311 of the top rod 31, so that the force-applying end 312 of the top rod 31 hits the other of the cabinet 50 and the cabinet door 60, causing it to vibrate, thereby breaking the ice frozen between the cabinet door 60 and the cabinet 50. The storage cabinet provided in this embodiment applies an impact force to the top rod 31 through the driving component 32 of the ice-breaking mechanism 3. The impact force of the top rod 31 is used to break the ice frozen between the cabinet door 60 and the cabinet body 50, thereby making it easy to open the cabinet door 60.

[0078] This embodiment exemplifies a configuration where the top rod 31 is movably mounted on the cabinet 50, and the drive assembly 32 is configured to apply an impact force to the force-receiving end 311 of the top rod 31, causing the force-applying end 312 of the top rod 31 to impact the cabinet door 60. In other embodiments, the top rod 31 can also be movably mounted on the cabinet door 60, and the drive assembly 32 can be configured to apply an impact force to the force-receiving end 311 of the top rod 31, causing the force-applying end 312 of the top rod 31 to impact the cabinet 50.

[0079] In this embodiment, the cabinet 50 includes a cabinet side wall 501 and a mounting housing 502 detachably connected to the cabinet side wall 501. The top rod 31 is movably connected to the mounting housing 502, and the drive assembly 32 is fixedly connected to the mounting housing 502. During installation, the ice-breaking mechanism 3 can be installed on the mounting housing 502 first, and then the mounting housing 502 can be connected to the cabinet side wall 501.

[0080] Optionally, referring to Figures 10 to 12, the drive assembly 32 includes a drive member 321. The drive member 321 includes an electric telescopic rod 322 capable of reciprocatingly extending and retracting. When the drive member 321 is energized, the electric telescopic rod 322 extends and strikes the force-receiving end 311 of the top rod 31, causing the force-applying end 312 of the top rod 31 to impact the cabinet door 60. When the drive member 321 is de-energized, the electric telescopic rod 322 retracts, and the impact force exerted by the electric telescopic rod 322 on the top rod 31 disappears. Optionally, by repeatedly switching the drive member 321 on and off, the electric telescopic rod 322 will intermittently strike the force-receiving end 311 of the top rod 31, thereby causing the force-applying end 312 of the top rod 31 to repeatedly impact the cabinet door 60.

[0081] The driving component 321 can be an electric actuator, and correspondingly, the electric telescopic rod 322 is the actuator of the electric actuator; or, the driving component 321 can also be an electromagnet, and correspondingly, the electric telescopic rod 322 is the armature of the electromagnet.

[0082] Optionally, referring to Figures 10 to 12, the drive assembly 32 further includes a transmission member 323. The transmission member 323 is rotatably connected to the cabinet door 60 or cabinet body 50 on which the top rod 31 is mounted. The transmission member 323 has a starting position and an impact position during its rotation stroke. When the transmission member 323 is in the starting position, the transmission member 323 is separated from the top rod 31. When the transmission member 323 is in the impact position, the transmission member 323 abuts against the top rod 31. The drive member 321 is connected to the transmission member 323. The drive member 321 is configured to drive the transmission member 323 to rotate from the starting position to the impact position so that the transmission member 323 impacts the force-receiving end 311 of the top rod 31, thereby applying an impact force to the force-receiving end 311 of the top rod 31.

[0083] Optionally, referring to Figures 10 to 12, the first end of the transmission component 323 is rotatably connected to the cabinet door 60 or cabinet body 50 on which the top rod 31 is mounted via the first shaft 33. When the transmission component 323 is in the impact position, the second end of the transmission component 323 abuts against the force-bearing end 311 of the top rod 31. The connection between the driving component 321 and the transmission component 323 is located between the first end and the second end of the transmission component 323. This arrangement can simplify the volume of the mounting housing 502 and ensure the stability of the driving component 321 when it strikes the top rod 31.

[0084] Optionally, referring to Figures 10 to 12, the ice-breaking mechanism 3 also includes a first elastic element 328, which is connected to the transmission element 323 to ensure that the transmission element 323 always tends to rotate towards the starting position. This arrangement allows the transmission element 323 to rotate to the starting position under the action of the first elastic element 328 when the electric telescopic rod 322 retracts. When the electric telescopic rod 322 extends, it pushes the transmission element 323 to rotate and increases the rotational speed of the transmission element 323. As a result, when the second end of the transmission element 323 strikes the top rod 31, it can generate a greater impact force. By repeatedly extending and retracting the electric telescopic rod 322, the electric telescopic rod 322 repeatedly impacts the top rod 31, causing the top rod 31 to repeatedly impact the cabinet door 60, resulting in a better ice-breaking effect. Furthermore, when the ice between the cabinet door 60 and the cabinet body 50 is broken, the top rod 31 moves to the extended position under the combined action of the first elastic element 328 and the drive assembly 32, ensuring that the force of the top rod 31 impacting the cabinet door 60 is greater, and that the cabinet door 60 can be opened more reliably. In this embodiment, the first elastic element 328 can be a compression spring, tension spring, etc.

[0085] Optionally, referring to Figures 10 to 12, the top rod 31 is slidably connected to the mounting housing 502. The top rod 31 can slide relative to the mounting housing 502 and has an extended position and a retracted position. The ice-breaking mechanism 3 also includes a second elastic element 37, which is connected to the top rod 31. Under the action of the second elastic element 37, the top rod 31 always has a tendency to slide towards the extended position. When the cabinet door 60 is closed, the cabinet door 60 presses the top rod 31 to the retracted position. Under the action of the second elastic element 37, the force-applying end 312 of the top rod 31 presses against the cabinet door 60.

[0086] Optionally, the locker also includes a controller and a sensor 40. The drive assembly 32, sensor 40, and lock are all electrically connected to the controller. The sensor 40 is configured to detect whether the top rod 31 is in the extended position (i.e., whether the locker door 60 is open). When the top rod 31 is in the extended position, the sensor 40 outputs a first signal; when the top rod 31 is in the retracted position, the sensor 40 outputs a second signal. When the locker door 60 is to be opened, if there is ice between the locker door 60 and the locker body 50, the locker door 60 cannot be opened after the controller unlocks the lock. When the locker door 60 cannot be opened, the sensor 40 will continuously output the second signal. Accordingly, the controller can also determine that the locker door 60 is not open based on the second signal. At this time, the controller will control the drive assembly 32 to intermittently strike the top rod 31 until the output signal of the sensor 40 changes from the second signal to the first signal. The controller then determines that the locker door 60 is open based on the first signal and controls the drive assembly 32 to stop striking the top rod 31.

[0087] The storage cabinet provided in this embodiment applies an impact force to the top rod 31 installed on either the cabinet body 50 or the cabinet door 60 via the drive assembly 32 of the ice-breaking mechanism 3. This causes the top rod 31 to strike the other of the two components, breaking the ice frozen between the cabinet door 60 and the cabinet body 50, thus allowing the cabinet door 60 to be opened easily. Compared to melting ice by heating with an electric heating cable, this ice-breaking method is more efficient, reduces energy consumption, and improves energy utilization.
