[0030] To make the objectives, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] The inventor found through analyzing the prior art that: the reason why the existing traditional lock structures are easily cracked by means such as lock picking and drilling is that these locks can directly contact the lock core by inserting tools into the keyhole. Therefore, the design without a keyhole can cleverly avoid the above defects of traditional locks. On this basis, the non-contact interaction between the key and the lock core can be realized by magnetic force to achieve unlocking.

[0032] Referring to Figures 1-9 , there is shown a magnetic switch lock provided by an embodiment of the present application, including a lock beam 1, a lock body 2, a driving component 3, and a magnetic unlocking part 4; the first end of the lock beam 1 is movably connected to the lock body 2, and the second end of the lock beam 1 is disposed in the opening on the first surface of the lock body 2; the driving component 3 is in limit cooperation with the second end of the lock beam 1;

[0033] The driving component 3 is disposed in the opening on the second surface of the lock body 2, and there are several movable magnetic lock cores 5 between the driving component 3 and the lock body 2; the lock body 2 is in limit cooperation with the driving component 3 through the magnetic lock cores 5;

[0034] One side surface of the magnetic unlocking part 4 is provided with a first positioning part 41 and several magnetic parts;

[0035] The driving component 3 is provided with a second positioning part 31 corresponding to the first positioning part 41;

[0036] When unlocking, one side surface of the magnetic unlocking part 4 is attached to the driving component 3, the first positioning part 41 cooperates with the second positioning part 31, and the combined magnetic field of the several magnetic parts makes the several magnetic lock cores 5 all release the limit on the driving component 3. Through the common movement of the magnetic unlocking part 4 and the driving component 3, the driving component 3 releases the limit on the second end of the lock beam 1.

[0037] In an embodiment of the present application, compared with the existing traditional lock structures that are easily cracked by violent means such as lock picking and drilling, the present application provides a magnetic switch lock, including a lock beam 1, a lock body 2, a driving component 3, and a magnetic unlocking component 4; the first end of the lock beam 1 is movably connected to the lock body 2, and the second end of the lock beam 1 is disposed in an opening on the first surface of the lock body 2; the driving component 3 is in limit cooperation with the second end of the lock beam 1; the driving component 3 is disposed in an opening on the second surface of the lock body 2, and a plurality of movable magnetic lock cores 5 are provided between the driving component 3 and the lock body 2; the lock body 2 is in limit cooperation with the driving component 3 through the magnetic lock cores 5; one side surface of the magnetic unlocking component 4 is provided with a first positioning portion 41 and a plurality of magnetic members; the driving component 3 is provided with a second positioning portion 31 corresponding to the first positioning portion 41; when unlocking, one side surface of the magnetic unlocking component 4 is attached to the driving component 3, the first positioning portion 41 cooperates with the second positioning portion 31, and the combined magnetic field of the plurality of magnetic members causes the plurality of magnetic lock cores 5 to all release the limit on the driving component 3, and through the common movement of the magnetic unlocking component 4 and the driving component 3, the driving component 3 releases the limit on the second end of the lock beam 1. The technical problem that the existing traditional lock structures are easily cracked by violent means such as lock picking and drilling is solved, and the technical effect of locking by magnetic force and improving the reliability of the lock is achieved.

[0038] Next, a magnetic switch lock in the present exemplary embodiment will be further described.

[0039] It should be noted that complex magnetic force encodings can be formed by combining the plurality of magnetic members with different intensities, and only the correct combination of magnetic force encodings can unlock the lock. This mechanism not only increases the complexity of unlocking but also ensures a high level of confidentiality during use. The magnetic lock cores 5 and the magnetic members can be either attractive or repulsive. The magnetic members can be made of permanent magnetic materials or electromagnetic materials.

[0040] When the magnetic switch lock is a padlock, the magnetic lock cores 5 and the driving component 3 are both disposed on the side wall of the lock body 2, making full use of the side wall of the padlock as the contact surface for unlocking. Compared with the traditional lock core disposed on the opposite side of the lock beam 1, the side wall of the padlock usually has a larger contact area and can accommodate more magnetic lock cores 5 to form rich magnetic force encodings.

[0041] The common movement of the magnetic unlocking component 4 and the driving component 3 can be a translational movement or a rotational movement, and the structure of the driving component 3 can be correspondingly set according to its movement mode.

[0042] In an embodiment of the present application, with reference to Figures 2-5The driving assembly 3 includes a rotating member 32 and a movable rod 33; a protrusion 321 is provided on one side of the rotating member 32, and a groove 331 corresponding to the protrusion 321 is provided on one side of the movable rod 33; the protrusion 321 cooperates with the groove 331; one end of the movable rod 33 cooperates with the second end of the locking beam 1;

[0043] When unlocking, the magnetic unlocking member 4 rotates together with the rotating member 32, and the joint movement of the protrusion 321 and the groove 331 causes the movable rod 33 to move along its axial direction until one end of the movable rod 33 is disengaged from the limit position of the second end of the lock beam 1.

[0044] It should be noted that the rotating member 32 may be provided with a step surface, and the lock body 2 limits the rotating member 32 to the inner side of the opening on the second surface of the lock body 2 through the step surface.

[0045] In one embodiment of the present application, refer to Figure 5 The plurality of magnetic lock cores 5 are arranged in a circular array, and the plurality of magnetic parts correspond one to one with the plurality of magnetic lock cores 5 .

[0046] It should be noted that an opening for accommodating the magnetic lock core 5 is correspondingly provided between the lock body 2 and the driving assembly 3 .

[0047] In one embodiment of the present application, refer to Figure 6 and Figure 8 The first positioning portion 41 includes at least one positioning column, and the second positioning portion 31 includes at least one positioning hole 311 , and the positioning column corresponds to the positioning hole 311 one by one.

[0048] It should be noted that the shape of the positioning hole 311 can be irregular, and the arrangement of multiple positioning holes 311 can also be irregular. The shapes of the positioning column and the positioning hole 311 can cooperate with each other, which improves the safety of the lock to a certain extent in the mechanical cooperation between the magnetic unlocking part 4 and the driving assembly 3.

[0049] In one embodiment of the present application, refer to Figure 8 One side of the magnetic unlocking member 4 is provided with an opening for accommodating the positioning column and the magnetic member.

[0050] It should be noted that the magnetic part can be a columnar structure, and the positioning column and the magnetic part are both arranged in an opening on one side of the magnetic unlocking part 4, wherein the positioning column protrusion is arranged on one side of the magnetic unlocking part 4 so that the positioning column can cooperate with the positioning hole 311.

[0051] In one embodiment of the present application, refer to Figure 3, the lock beam 1 is of a U-shaped structure, and the driving assembly 3 is arranged between the first end and the second end of the lock beam 1. This structure makes full use of the structure inside the lock beam 1 in the lock body 2, improving the overall compactness of the lock structure.

[0052] In an embodiment of the present application, referring to Figures 8-9 , one end of the magnetic unlocking member 4 is of a cylindrical structure, and the first positioning portion 41 and the plurality of magnetic members are arranged on one end face of the cylindrical structure.

[0053] It should be noted that the contact surface between the magnetic unlocking member 4 and the driving assembly 3 is a circular surface, so that more magnetic members can be accommodated on this contact surface to form a rich magnetic force code.

[0054] In an embodiment of the present application, referring to Figures 8-9 , the other end of the magnetic unlocking member 4 is provided with a holding portion 42; the holding portion 42 includes a rib 421; through holes 422 are provided on both side surfaces of the rib 421.

[0055] It should be noted that an arc-shaped structure can be adopted for transition between the rib 421 of the holding portion 42 and the magnetic unlocking member 4, and the through holes 422 can be used for threading a rope or a ring, making the magnetic unlocking member 4 convenient to carry as an unlocking key.

[0056] In an embodiment of the present application, the magnetic lock core 5 includes a first cylindrical pin, a second cylindrical pin and a spring; the first cylindrical pin is arranged on the driving assembly 3, the second cylindrical pin is arranged on the lock body 2, one end of the second cylindrical pin abuts against the first cylindrical pin, and the other end of the second cylindrical pin abuts against the lock body 2 through the spring.

[0057] It should be noted that different from the conventional mechanical pin tumbler lock, the first cylindrical pin, the second cylindrical pin and the spring can be distributed in a plane in the lock body 2 in groups respectively.

[0058] In an embodiment of the present application, a magnetic shielding member is further included. The magnetic shielding member is arranged outside the plurality of magnetic lock cores 5, and the magnetic shielding member is provided with pores corresponding to the magnetic fields of the magnetic lock cores 5.

[0059] It should be noted that the magnetic shielding member is disposed around the lock core. Such a position can isolate the stable magnetic field inside the lock core to the greatest extent and prevent the influence of external interference factors. To ensure that the magnetic shielding member does not affect the normal locking and unlocking, appropriate pores are provided on the magnetic shielding member to allow necessary magnetic force to penetrate, so as to ensure normal locking and unlocking operations; alternatively, the thickness of the magnetic shielding member can be controlled within a reasonable range, which can effectively shield the external magnetic field without overly weakening the magnetic coupling between the lock core and the magnetic unlocking member 4.

[0060] Although the preferred embodiments of the embodiments of the present application have been described, those skilled in the art can make additional changes and modifications once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the present application.

[0061] Finally, it should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or terminal device.
