[0004] Although the electromagnetic lock of the above structure has anti-vibration opening structure, when vibration, the counterweight moves down to drive the other end of the rotating rod to be upturned for limiting, but in the process of continuous vibration, the counterweight jumps up and down, which may cause the counterweight to slide up at a moment, and the other end of the rotating rod to drop, and the lock tongue to jump down at this moment and directly unlock, resulting in automatic unlocking of the electromagnetic lock under vibration or impact; on the other hand, in the static state, one end of the rotating rod is always in the retraction path of the lock tongue, resulting in the need to press down one end of the rotating rod to do work during the unlocking process of the electromagnetic lock, and then unlock, which brings greater power consumption; and the above electromagnetic lock only has the function of electromagnetic lock unlocking and anti-vibration, and does not have the function of mechanical unlocking and anti-vibration, so further improvement is needed. UTILITY MODEL CONTENTS
[0005] The utility model aims at solving one of the technical problems existing in the prior art.
[0006] The application provides an electromagnetic lock with an anti-vibration structure, which comprises a shell, a coil and a bolt that can extend out of the shell under the power control of the coil, characterized in that a fixing plate is arranged between the bolt and the output end of the coil, an anti-vibration plate is arranged on the bolt, a first elastic member is arranged between the anti-vibration plate and the fixing plate, an anti-vibration assembly is arranged in the shell, the anti-vibration assembly comprises a rotating block that is rotatably arranged in the shell, the first rotating direction of one end of the rotating block is limited by a first limiting block, the second rotating direction of the rotating block is rotated into the travel path of the anti-vibration plate along with the lifting of the bolt under the vibration condition, the rotating block is located on one side of the travel path under the non-vibration condition, and a second elastic member that is used for driving the rotating block to rotate back and forth during the vibration process is arranged on the other side of the rotating block.
[0007] Preferably, the shell is provided with a second limiting block that is used for limiting the rotating amplitude of the rotating block in cooperation with the first limiting block.
[0008] Preferably, under the non-vibration condition, the one end of the rotating block leans against the first limiting block, and the spacing between the other side of the rotating block and the second limiting block is arranged to be 0.1-2 mm.
[0009] Preferably, the rotating angle of the rotating block is controlled to be 1-6° under the combined limiting action of the first limiting block and the second limiting block.
[0010] Preferably, the spacing between the one end of the rotating block that faces the anti-vibration plate and the travel path of the anti-vibration plate is arranged to be 0.1-1 mm.
[0011] Preferably, the anti-vibration plate comprises a flat plate that is used for cooperating with the first elastic member and a T-shaped vertical plate, the flat plate is connected with the bolt, the first elastic member is arranged between the flat plate and the fixing plate, an opening through which the lower end of the vertical plate slides downward is arranged between the fixing plate and the shell, and when the vibration occurs, the upper end of the rotating block rotates to the right and limits the descent of the vertical plate, thereby avoiding the automatic unlocking of the bolt.
[0012] Preferably, the opening is arranged in an L shape, and a reinforcing plate is fixedly connected to the side of the vertical plate that is close to the rotating block, and when the vibration occurs, the vertical plate and the rotating block slide through the L-shaped opening and then continue to descend downward in cooperation with the limiting of the rotating block.
[0013] Preferably, a mechanical key lock cylinder is further arranged in the shell, and the mechanical key lock cylinder is in transmission connection with the anti-vibration plate through a transmission assembly.
[0014] Preferably, the transmission assembly comprises a connecting plate that is connected with the anti-vibration plate and a transmission plate that is arranged to ascend and descend in the shell, a transmission hook part is arranged on the side of the transmission plate that faces the connecting plate, a cooperation hook part is arranged on the side of the connecting plate that faces the transmission plate and is located below the transmission hook part, and the transmission plate is in transmission connection with the output end of the mechanical key lock cylinder.
[0015] Preferably, the transmission plate is provided with a plurality of transmission teeth, and the transmission plate is connected to the gear transmission of the mechanical key lock cylinder output part through the plurality of transmission teeth. After the correct key is inserted, the mechanical key lock cylinder can rotate the gear to drive the transmission plate to descend. The transmission plate drives the connecting plate and the anti-vibration plate to descend synchronously through the transmission hook part, thereby realizing the retraction of the lock tongue to unlock.
[0016] The electromagnetic lock with a vibration-damping structure described above completely solves the problem of mis-locking due to vibration / impact: Compared with the traditional counterweight plus rotating rod structure, which is prone to jumping up and down during continuous vibration and causing the lock tongue to mis-lock, this application uses a rotating block to accurately rotate into the path of the vibration-damping plate during vibration, structurally blocking the abnormal downward movement of the lock tongue (lock rod), avoiding automatic unlocking caused by vibration / impact, and making the protection more reliable.
[0017] Overcoming the problem that the limiting component in the traditional structure continuously occupies the retraction path of the lock tongue, resulting in extra work required for unlocking, the rotating block is located on one side of the travel path when there is no vibration. During the unlocking process, there is no need to overcome the resistance of the limiting component, which significantly reduces the power consumption of the coil-driven unlocking and improves energy efficiency.
[0018] The addition of a mechanical key lock cylinder and transmission components enables dual-mode unlocking, including both electromagnetic and mechanical unlocking. Both modes maintain vibration resistance, expanding the adaptability to high-end scenarios such as gun cabinets that have multiple unlocking requirements.
[0019] By using the dual limiting of the first and second limiting blocks, the rotation angle of the rotating block is controlled within 1-6°, and the distance between the rotating block and the travel path of the vibration damping plate is controlled within 0.1-1mm. This ensures both rapid response and limiting during vibration and avoids interference during normal unlocking, resulting in more precise control.
[0020] The T-shaped longitudinal plates, L-shaped openings, and reinforcing plates of the vibration damping plate further enhance the load-bearing capacity of the limiting structure, preventing component deformation caused by vibration and impact during long-term use and extending the product's service life.
[0021] Mechanical key unlocking uses precise transmission between the transmission teeth, transmission hook, and cooperating hook to drive the anti-vibration plate to descend synchronously. This allows the anti-vibration structure to be damaged while unlocking, ensuring that the anti-vibration function is always effective in both electromagnetic and mechanical unlocking modes, thus improving the comprehensiveness and reliability of the product.
[0022] The beneficial effects of this invention will be explained in detail in the embodiments, thereby making the beneficial effects more obvious. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0033] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.
[0034] Example 1:
[0035] likeFigures 1-8 As shown, an electromagnetic lock with an anti-vibration structure includes a housing 1, a coil 2, and a latch 3 that extends out of the housing 1 when the coil 2 is energized. In a specific embodiment of this invention, a fixing plate 4 is provided between the latch 3 and the output end of the coil 2. An anti-vibration plate 5 is provided on the latch 3. A first elastic element 6 is provided between the anti-vibration plate 5 and the fixing plate 4. An anti-vibration assembly is provided inside the housing 1. The anti-vibration assembly includes a rotating block 7 rotatably disposed inside the housing 1. A first rotation direction of one end of the rotating block 7 is limited by a first limiting block 8. A second rotation direction, under vibration, rotates into the travel path of the anti-vibration plate 5 as the latch 3 rises and falls. Under non-vibration conditions, the rotating block 7 is located on one side of the travel path. A second elastic element 9 is provided on the other side of the rotating block 7 to drive the rotating block 7 to rotate back and forth during vibration. In a specific embodiment of this invention, a second limiting block 10 is provided inside the housing 1 to limit the rotation amplitude of the rotating block 7 in conjunction with the first limiting block 8. Figure 3 As shown, the rotating block 7 is rotatably mounted on a pre-set mounting base inside the housing 1 via a rotating shaft (unlabeled), and is located below the fixing plate 4. The first elastic element 6 and the second elastic element 9 are both helical compression springs.
[0036] By adopting the above technical solution, compared with the traditional counterweight plus rotating rod structure, which is prone to jumping up and down under continuous vibration and causing the lock tongue to mis-lock, the anti-vibration component design with rotating block, double limit block and second elastic element can accurately rotate into the travel path of the anti-vibration plate during vibration, directly blocking the abnormal downward movement of the lock tongue from the mechanical structure. Even in the face of continuous bumps and accidental impacts, it can avoid automatic unlocking, and the anti-vibration protection is more stable and reliable. It breaks through the problem that the limit component in the traditional structure continuously occupies the lock tongue retraction path, causing the unlocking to require additional work to overcome resistance. In this embodiment, the rotating block is located on one side of the travel path when there is no vibration. During the unlocking process, no additional energy is required to overcome the resistance of the limit component, which significantly reduces the power consumption of the coil driving the unlocking, improves the energy efficiency of the product, and is more suitable for the needs of low power consumption scenarios.
[0037] In a specific embodiment of this utility model, when there is no vibration, one end of the rotating block 7 rests against the first limiting block 8, and the distance between the other side and the second limiting block 10 is set at 0.1-2mm.
[0038] In a specific embodiment of this utility model, the rotating block 7 can rotate at an angle of 1-6° under the combined limiting action of the first limiting block 8 and the second limiting block 10.
[0039] In a specific embodiment of this utility model, the distance between the end of the rotating block 7 that rotates toward the vibration damping plate 5 and the travel path of the vibration damping plate 5 is set at 0.1-1mm.
[0040] With the dual constraints of the first and second limiting blocks, the rotation angle of the rotating block is strictly controlled within 1-6°, and the distance between the rotating block and the travel path of the vibration damping plate is limited to 0.1-1mm. This ensures that the rotating block responds quickly and is limited in time during vibration, while avoiding structural interference during normal unlocking, resulting in better synergy between vibration damping and unlocking.
[0041] In a specific embodiment of this utility model, the vibration damping plate 5 includes a flat plate 51 for cooperating with the first elastic member 6 and a T-shaped longitudinal plate 52. The flat plate 51 is connected to the locking tongue 3. The first elastic member 6 is disposed between the flat plate 51 and the fixed plate 4. An opening is provided between the fixed plate 4 and the housing 1 for the lower end of the longitudinal plate 52 to slide downward. If vibration occurs during the downward movement of the longitudinal plate 52, the upper end of the rotating block 7 rotates to the right and limits the descent of the longitudinal plate 52, thereby preventing the locking tongue 3 from unlocking automatically.
[0042] In a specific embodiment of this utility model, the opening is set in an L-shape, and a reinforcing plate 53 is fixedly connected to the side of the longitudinal plate 52 near the rotating block 7. When vibration occurs, the longitudinal plate 52 and the rotating block 7 slide down through the L-shaped opening and then continue to descend downward in coordination with the rotating block 7 to limit their descent.
[0043] The vibration damping plate adopts an integrated design of a flat plate and a T-shaped longitudinal plate. A reinforcing plate is added to one side of the longitudinal plate, and the opening between the fixing plate and the shell is L-shaped, which greatly improves the load-bearing capacity of the limiting structure under vibration and impact, and avoids vibration damping failure due to component deformation during long-term use.
[0044] Example 2:
[0045] like Figures 1-8 As shown, the difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the present invention, the housing 1 is also provided with a mechanical key lock cylinder 11, which is connected to the vibration damping plate 5 via a transmission assembly.
[0046] In a specific embodiment of this utility model, the transmission assembly includes a connecting plate 12 connected to the vibration damping plate 5 and a transmission plate 13 that is lifted and lowered inside the housing 1. The transmission plate 13 is provided with a transmission hook 15 on the side facing the connecting plate 12, and a cooperating hook 16 is provided on the side facing the transmission plate 13 and below the transmission hook 15. The transmission plate 13 is connected to the output end of the mechanical key lock cylinder 11.
[0047] In a specific embodiment of this utility model, the transmission plate 13 is provided with a plurality of transmission teeth 14. The transmission plate 13 is connected to the gear transmission of the output part of the mechanical key lock cylinder 11 through the plurality of transmission teeth 14. After the correct key is inserted, the mechanical key lock cylinder 11 can rotate the gear to drive the transmission plate 13 to descend. The transmission plate 13 drives the connecting plate 12 and the anti-vibration plate 5 to descend synchronously through the transmission hook part 15 and the engagement hook part 16, thereby realizing the retraction of the lock tongue 3 to unlock.
[0048] like Figure 7 As shown, the fixed plate 4 is also provided with a lifting hole (unlabeled) for the transmission plate 13 to move up and down therein, and a pressure plate 100 is also connected below the fixed plate 4 to cooperate with the inner wall of the housing 1 to provide space for the transmission plate 13 to move up and down therein, so that the lifting process of the transmission plate 13 is more stable.
[0049] By adopting the above technical solution, compared with the existing technology, this embodiment adds a mechanical key lock cylinder and matching transmission components to construct a dual-mode system of electromagnetic unlocking and mechanical unlocking. This solves the limitation of traditional electromagnetic locks, which only have a single unlocking method and lack mechanical unlocking vibration damping function. In both unlocking modes, the vibration damping components can respond to vibration in real time, ensuring that the vibration damping function is always effective. This expands the adaptability to high-end scenarios such as gun cabinets and safes for valuables, which have dual requirements for unlocking flexibility and security.
[0050] Through the precise meshing of the transmission teeth, transmission hook and cooperating hook, the mechanical key can stably drive the anti-vibration plate to descend synchronously when unlocking, so as to retract the lock tongue without damaging the anti-vibration structure. This ensures both the convenience of emergency unlocking (the correct key can be inserted to drive it) and the reliability of anti-vibration.

For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.
