Description

Technical Field

[0001] This application relates to the field of terminal cabinets, and in particular to a magnetic lock structure, a smart cabinet, a food cabinet, and a drone cabinet. Background Technology

[0002] Through technological integration and scenario innovation, various types of terminal cabinets with different functions are available on the market, such as smart cabinets (e.g., storage cabinets, express delivery cabinets, logistics cabinets, refrigerated cabinets), food cabinets, drone cabinets, etc. These terminal cabinets are gradually becoming important infrastructure for smart cities and industrial upgrading.

[0003] Most terminal cabinets include a cabinet door and a lock that works in conjunction with it. The cabinet door and lock are the basic components for achieving security functions. Currently, some terminal cabinets use magnetic locks. Typically, the metal block of the magnetic lock is installed on the cabinet door, and the lock body is installed on the cabinet body. When the cabinet door is closed, the metal block is firmly attracted by the lock body, achieving the technical purpose of locking.

[0004] The installation of magnetic locks requires repeated adjustments to the cabinet door and the metal block to ensure that the metal block can properly lock with the lock body when the door is closed. Therefore, the installation of magnetic locks is quite cumbersome. Furthermore, with the use of the terminal cabinet, the cabinet door may deform due to external forces or environmental factors. This deformation may prevent the metal block of the magnetic lock from fully fitting with the lock body, thus affecting the lock's attraction and stability, and even potentially causing the lock to fail to lock properly, posing a significant safety hazard. Utility Model Content

[0005] This application provides a magnetic lock structure, a smart cabinet, a food cabinet, and a drone cabinet. The magnetic lock structure has an adaptive adjustment function, which not only facilitates installation but also solves the problem of unreliable locking caused by cabinet door deformation during use to a certain extent.

[0006] Firstly, the magnetic lock structure provided in this application includes:

[0007] The first lock body is fixed to the cabinet and has a first adsorption surface;

[0008] A joint ball, rotatably connected to the door body, the joint ball being able to rotate relative to the door body about the center of the joint ball; and

[0009] The second lock body is fixed to the joint ball and magnetically attracted to the first lock body, and the second lock body has a second adsorption surface;

[0010] The door is closable and connected to the cabinet. When the door is closed, the second lock can rotate relative to the door until the second adsorption surface is attached to the first adsorption surface under the adsorption action of the first lock.

[0011] In some embodiments, the magnetic lock structure further includes:

[0012] A first plate is fixed to the door body, and a first limiting hole is provided on the first plate. The diameter of the first limiting hole is smaller than the diameter of the joint ball.

[0013] The second plate is fixed to the first plate, and the second plate is an elastic plate;

[0014] The articulated ball is placed between the first plate and the second plate, and is partially exposed in the first limiting hole and connected to the second lock body.

[0015] In some embodiments, the first plate body is provided with a plurality of second limiting holes;

[0016] The magnetic lock structure also includes multiple pins, which are respectively fixed to the side of the second lock body facing the first plate. The pins are inserted into the second limiting hole in a one-to-one correspondence, and the diameter of the pin is smaller than the diameter of the second limiting hole.

[0017] In some embodiments, the first plate has two second limiting holes, and the magnetic lock structure includes two pins, which are symmetrically arranged on both sides of the joint ball.

[0018] In some embodiments, when the second adsorption surface is attached to the first adsorption surface, the included angle between the second adsorption surface and the first plate is less than or equal to 5°.

[0019] In some embodiments, the magnetic lock structure further includes a washer sandwiched between the second lock body and the ball joint.

[0020] In some embodiments, the magnetic lock structure further includes a first bolt and a first nut, the first bolt passing sequentially through the second lock body and the ball joint, and the first nut being threadedly connected to the first bolt to secure the second lock body and the ball joint.

[0021] Secondly, the smart cabinet provided in this application includes a magnetic lock structure as described in any embodiment of the first aspect.

[0022] Thirdly, the food cabinet provided in this application includes a magnetic lock structure as described in any embodiment of the first aspect.

[0023] Fourthly, the drone cabinet provided in this application includes a magnetic lock structure as described in any embodiment of the first aspect.

[0024] Based on the above technical solution, during the door closing process, as the second lock body gradually approaches the first lock body, under the adsorption of the first lock body, the second lock body can adaptively rotate relative to the door body. This allows the second adsorption surface of the second lock body to precisely adhere to and adsorb onto the first adsorption surface of the first lock body. This eliminates the need for repeated manual adjustments to the positions of the first and second lock bodies, ensuring that the second lock body can lock securely with the first lock body after the door is closed. This simplifies the installation process and improves installation efficiency. With the use of magnetic locks, even if the door body deforms due to external forces or environmental factors, the second lock body can still adaptively adjust its angle under the combined action of the first lock body and the ball joint to fit the first lock body. This solves the problem of the second lock body failing to reliably lock with the first lock body due to door deformation, effectively guaranteeing the locking effect and enhancing security.

Detailed Implementation

[0034] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0035] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be intermediate components present. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be intermediate components present.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] Please refer to Figures 1 to 8 The magnetic lock structure in this embodiment is used for opening and closing between cabinet 1 and door 2, that is, door 2 is closable and connected to cabinet 1. The magnetic lock structure includes a first lock body 3, a second lock body 4, and a ball joint 5. The first lock body 3 is fixed to cabinet 1 and has a first adsorption surface 31. The ball joint 5 is rotatably connected to door 2 and can rotate relative to door 2 around its own center point. The second lock body 4 is fixed to ball joint 5, so the second lock body 4 can also rotate relative to door 2. Furthermore, the second lock body 4 is magnetically attracted to the first lock body 3 and has a second adsorption surface 41. When door 2 is closed, under the adsorption of the first lock body 3, the second lock body 4 can rotate relative to door 2 until the second adsorption surface 41 is attached to the first adsorption surface 31.

[0038] In this embodiment, during installation, the first lock body 3 can be fixed to the cabinet 1 first, and then the second lock body 4 can be connected to the door 2 via the ball joint 5. During the closing process of the door 2, as the second lock body 4 gradually approaches the first lock body 3, under the adsorption of the first lock body 3, the second lock body 4 can adaptively rotate relative to the door 2, thereby allowing the second adsorption surface 41 of the second lock body 4 to precisely adhere to and adsorb onto the first adsorption surface 31 of the first lock body 3. This eliminates the need for repeated manual adjustments to the positions of the first lock body 3 and the second lock body 4, ensuring that the second lock body 4 can lock securely with the first lock body 3 after the door 2 is closed. This simplifies the installation process and improves installation efficiency. With the use of the magnetic lock, even if the door 2 deforms due to external forces or environmental factors, the second lock body 4 can still adaptively adjust its angle under the combined action of the first lock body 3 and the ball joint 5 to fit the first lock body 3. This solves the problem of the second lock body 4 failing to reliably lock with the first lock body 3 due to door 2 deformation, effectively guaranteeing the locking effect and enhancing security.

[0039] In some implementation methods, please refer to Figure 2 As shown, the door 2 has a first side 21 and a second side 22 arranged opposite each other in the left-right direction, or a first side 21 and a second side 22 arranged opposite each other in the up-down direction. The first side 21 of the door 2 can be connected to the cabinet 1 by a hinge, and the second lock body 4 is disposed on the second side 22 of the door 2. In some embodiments, the first side 21 and the second side 22 of the door 2 can be arranged adjacent to each other, that is, the hinge and the second lock body 4 are respectively located on two mutually perpendicular sides of the door 2. It should be noted that the number of magnetic lock structures can be flexibly set, for example, please refer to Figure 1 As shown, the upper end of the door 2 is connected to the cabinet 1 by a hinge, and a second lock body 4 is provided on both the left and right sides of the door 2. That is, a door 2 is provided with two magnetic lock structures.

[0040] In some embodiments, the second lock body 4 can be located inside the door 2, that is, when the door 2 is closed, the second lock body 4 is located inside the cabinet 1. Please refer to [reference needed]. Figure 1 As shown. In other embodiments, the second lock body 4 can be located outside the door 2, that is, when the door 2 is closed, the second lock body 4 is located outside the cabinet 1. Please refer to [reference needed]. Figure 2 As shown, you can set it according to the actual situation.

[0041] In some embodiments, when the door 2 is opened relative to the cabinet 1, the door 2 can rotate outward relative to the cabinet 1. In other embodiments, when the door 2 is opened relative to the cabinet 1, the door 2 can rotate inward relative to the cabinet 1. This can be configured according to actual conditions and is not limited here.

[0042] In some embodiments, at least one of the first locking body 3 and the second locking body 4 has magnetic attraction capability. For example, the first locking body 3 is an electromagnet, and the second locking body 4 is an armature. When the first locking body 3 is energized, it generates a magnetic field, thereby attracting the second locking body 4 that is close to the first locking body 3, thus locking the closed door 2. When the first locking body 3 is de-energized, it loses its magnetic force and no longer attracts the second locking body 4, allowing the door 2 to open. Another example is that the first locking body 3 is an armature, and the second locking body 4 is an electromagnet. Of course, the first locking body 3 and the second locking body 4 can also have other structures, as long as they can magnetically engage.

[0043] In some embodiments, the door body 2 can be made of sheet metal. Sheet metal door bodies 2 not only have high strength and rigidity, but also good corrosion resistance and impact resistance, resulting in a long service life. Although the sheet metal door body 2 may deform under the influence of external forces after prolonged use, in this embodiment, under the combined action of the first lock body 3 and the ball joint 5, the second lock body 4 can rotate relative to the door body 2 to fit against the first lock body 3, thereby offsetting the adverse effects of deformation of the door body 2.

[0044] In some implementation methods, please refer to Figures 3 to 8 The magnetic lock structure also includes a first plate 6 and a second plate 7. The first plate 6 is fixed to the door body 2 and has a first limiting hole 611, the diameter of which is smaller than the diameter of the ball joint 5. The second plate 7 is an elastic plate and is fixed to the first plate 6. The ball joint 5 is positioned between the first plate 6 and the second plate 7, with a portion of the ball joint 5 protruding from the first limiting hole 611 and connected to the second lock body 4.

[0045] In this embodiment, the articulated ball 5 is sandwiched between the first plate 6 and the second plate 7. Since the second plate 7 is an elastic plate, when the second locking body 4 is not attracted by the first locking body 3, the first plate 6 and the elastic second plate 7 can cooperate to clamp the articulated ball 5, thereby preventing the second locking body 4 from sagging under the action of gravity and ensuring that the door can be closed normally. Furthermore, since the second plate 7 is an elastic plate, it can undergo elastic deformation when subjected to a certain external force. Therefore, when the second locking body 4 is attracted by the first locking body 3, the attraction force is transmitted to the articulated ball 5 fixed to the second locking body 4. Under the action of the attraction force, the articulated ball 5 can overcome the elastic clamping from the first plate 6 and the second plate 7 and rotate together with the second locking body 4 until the second locking body 4 is in contact with the first locking body 3. In addition, the first plate 6 has a first limiting hole 611 that partially exposes the articulated ball 5, so that the articulated ball 5 can only rotate around the center of the articulated ball within the range limited by the first plate 6, the second plate 7, and the first limiting hole 611.

[0046] In one embodiment, the second plate 7 can be made of a metal elastic material such as spring steel or stainless steel. In other embodiments, the second plate 7 can also be made of other elastic materials, which can be set according to the actual situation, and will not be elaborated here.

[0047] As one implementation method, please refer to Figures 3 to 6 The first plate 6 may include a first plate portion 61, a first bent portion 62, and a second plate portion 63, which are connected sequentially. The first plate portion 61 and the second plate portion 63 may be parallel to each other. The first plate portion 61 is used to connect with the articulated ball 5. The second plate portion 63 is fixed to the door body 2. For example, the second plate portion 63 may be fitted to the door body 2 and fixed to the door body 2 by screws or other threaded parts. The second plate 7 includes a third plate portion 71, two second bent portions 72, and two fourth plate portions 73. The two fourth plate portions 73 are symmetrically arranged on both sides of the third plate portion 71 and are connected to the third plate portion 71 through a second bent portion 72, respectively. The third plate portion 71 is parallel to the first plate portion 61, and there is a gap between the third plate portion 71 and the first plate portion 61. The articulated ball 5 is placed between the third plate portion 71 and the first plate portion 61. The two fourth plate portions 73 are respectively fixed to the first plate portion 61 by the second threaded member 81, thereby fixing the first plate body 6 and the second plate body 7 together. As an example, the second threaded member 81 can be a second bolt 811 and a second nut 812 that cooperate with each other, or the threaded member can be a screw or other threaded member.

[0048] In some implementation methods, please refer to Figures 3 to 8 The first plate 6 has multiple second limiting holes 612. The magnetic lock structure also includes multiple pins 9, which are fixed to the side of the second lock body 4 facing the first plate 6. The number of pins 9 is equal to the number of second limiting holes 612, and they are arranged in a one-to-one correspondence. Each pin 9 is inserted into a corresponding second limiting hole 612. The diameter of each pin 9 is smaller than the diameter of the second limiting hole 612, so each pin 9 can rotate relative to the first plate 6 within the second limiting hole 612.

[0049] In this embodiment, the first plate 6 has a first surface 613 facing the second lock body 4. Multiple pins 9 work together to limit the range of rotation of the second lock body 4 around a first straight line L1 perpendicular to the first surface 613 and passing through the center of the joint ball, thereby preventing excessive rotation of the second lock body 4. Furthermore, the diameter of the pins 9 is smaller than the diameter of the second limiting hole 612, which not only avoids interfering with the normal rotation of the second lock body 4, but also prevents the second lock body 4 from continuing to rotate when the outer surface of the pins 9 abuts against the wall of the second limiting hole 612, thus effectively limiting the maximum rotation angle of the second lock body 4.

[0050] As one implementation method, please refer to Figures 3 to 8 The first plate 6 has two second limiting holes 612. The magnetic lock structure includes two pins 9, which are symmetrically arranged on both sides of the joint ball 5. The structure is not only simple but also highly stable, making the second lock body 4 more evenly stressed.

[0051] In this embodiment, the second lock body 4 can rotate relative to the door body 2 around the second straight line L2 and / or the third straight line L3. The second straight line L2 is perpendicular to the first plane and passes through the center of the joint ball. The third straight line L3 is located in the first plane and is perpendicular to the axis of the second limiting hole 612 and passes through the center of the joint ball. The first plane is the plane in which the axes of the two second limiting holes 612 are located.

[0052] It should be noted that in other embodiments, the first plate 6 may also have three, four, five or more second limiting holes 612, and correspondingly, the second lock body 4 may be fixed with three, four, five or more pins 9, which can be set according to the actual situation, and will not be described in detail here.

[0053] As an example, please refer to Figure 6 The axes of all pins 9 are arranged parallel to each other, and correspondingly, the axes of all second limiting holes 612 are arranged parallel to each other.

[0054] As an example, please refer to Figure 3 and Figure 6 The pin 9 can be a cotter pin, and an opening groove 91 extending axially is formed on the pin 9. The second lock body 4 has multiple mounting holes 42, the number of which equals the number of pins 9, and each mounting hole 42 corresponds to one pin 9. During installation, simply insert the pin 9 into the corresponding mounting hole 42. The pin 9 will open under its own elasticity and thus lock into the corresponding mounting hole 42, thereby achieving a fixed connection between the pin 9 and the second lock body 4. This not only facilitates installation but also ensures a secure fixation.

[0055] In some embodiments, when the second adsorption surface 41 is attached to the first adsorption surface 31, the included angle between the second adsorption surface 41 and the first plate 6 is less than or equal to 5°. This not only accommodates the deformation of the door body 2 but also prevents abnormal problems that may occur due to excessive rotation of the second lock body 4 relative to the door body 2. For example, the pin 9 and the mounting hole 42 can be structurally matched so that the included angle between the second adsorption surface 41 and the first plate 6 is less than or equal to 5°.

[0056] In some implementation methods, please refer to Figures 3 to 8The magnetic lock structure also includes a first threaded component 82, which comprises a first bolt 821 and a first nut 822. The first bolt 821 passes sequentially through the second lock body 4 and the ball joint 5, and the first nut 822 is threadedly connected to the first bolt 821 to fix the second lock body 4 and the ball joint 5. In this embodiment, the second lock body 4 and the ball joint 5 are fixed by the threaded first bolt 821 and the first nut 822, which not only facilitates installation but also facilitates disassembly and maintenance.

[0057] As one implementation method, please refer to Figures 5 to 8 The second plate 7 has a third limiting hole 711, which corresponds to the second limiting hole 612. The diameter of the third limiting hole 711 is smaller than the diameter of the joint ball 5, and part of the joint ball 5 is exposed through the third limiting hole 711. The cooperation between the third limiting hole 711 and the first limiting hole 611 allows the joint ball 5 to be placed more stably between the first plate 6 and the second plate 7, and to rotate more stably around the center of the joint ball. Moreover, since part of the joint ball 5 is exposed through the first limiting hole 611 and part of it is exposed through the third limiting hole 711 in the second plate 7, the maximum distance between the first plate 6 and the second plate 7 can be shortened, thereby making the magnetic lock structure smaller.

[0058] In some implementation methods, please refer to Figures 5 to 8 The magnetic lock structure also includes a washer 10, which is sandwiched between the second lock body 4 and the articulated ball 5. The washer 10 can be set to the required thickness according to actual needs, thereby adjusting the distance between the second lock body 4 and the articulated ball 5, allowing the second lock body 4 to rotate within a preset angle range. This not only makes it more flexible and convenient to use but also improves the installation accuracy of the second lock body 4. For example, when the distance between the second lock body 4 and the first plate 6 is too close, resulting in a maximum angle of 2° between the second adsorption surface 41 and the first plate 6, the existing washer 10 can be replaced with a thicker washer 10, allowing the maximum angle between the second adsorption surface 41 and the first plate 6 to reach 5°. Alternatively, when the distance between the second lock body 4 and the first plate 6 is too far, resulting in a maximum angle of 10° between the second adsorption surface 41 and the first plate 6, the existing washer 10 can be replaced with a thinner washer 10, controlling the maximum angle between the second adsorption surface 41 and the first plate 6 to approximately 5°.

[0059] As one implementation method, please refer to Figures 5 to 8 The magnetic lock includes a first bolt 821, a first nut 822 and a washer 10. The first bolt 821 passes through the second lock body 4, the washer 10 and the ball joint 5 in sequence. The first nut 822 is threaded to the first bolt 821 to fix the second lock body 4, the washer 10 and the ball joint 5.

[0060] It should be noted that in other embodiments, the joint ball and the second locking body can also be fixedly connected in other ways. For example, the joint ball and the second locking body can be an integrally formed structure, which can be set according to actual needs, and will not be elaborated here.

[0061] The smart locker in this application embodiment includes the magnetic lock structure described in any of the above embodiments. As an example, the smart locker can be, but is not limited to, a storage locker, a parcel locker, a logistics locker, or a refrigerated cabinet, etc.

[0062] The food cabinet in this application embodiment includes the magnetic lock structure described in any of the above embodiments.

[0063] The drone cabinet in this application embodiment includes the magnetic lock structure described in any of the above embodiments.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
