DETAILED DESCRIPTION OF THE EMBODIMENTS
[0033] The following will describe in detail the specific embodiments of the present disclosure with reference to the drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present disclosure, and do not limit the present disclosure.
[0034] In the present disclosure, unless otherwise stated, the orientation terms such as "inside" and "outside" are defined with respect to the outline of the corresponding component. The terms "first", "second", etc. are used to distinguish different components and do not have an order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.
[0035] According to an embodiment of the present disclosure, as Figures 1 to 7 shown, a passive electronic lock is provided, which includes a lock body 1, a shield 2, a cover 3, and an elastic member 4. Among them, the lock body 1 includes a lock body 10. A lock hole 11 is formed on one side of the lock body 10, and a metal contact 111 for cooperating with a key may also be provided in the lock hole 11. The shield 2 can be sleeved on the outside of the lock body 10, and a first opening 201 is formed on one side of the shield 2, and the lock hole 11 is located in the first opening 201. The cover 3 is located on one side of the first opening 201, and one end of the cover 3 is rotatably connected to the shield 2 for exposing or covering the first opening 201. The two ends of the elastic member 4 can be respectively connected to the shield 2 and the cover 3, and the elastic member 4 can provide a force that makes the end of the cover 3 away from the connection with the elastic member 4 approach the lock body 10.
[0036] Through the above technical solution, a shield 2 with a first opening 201 on one side of the lock hole 11 is installed outside the lock body 1 of the passive electronic lock. The shield 2 can protect the surface of the lock body 10, reduce the surface wear of the lock body 10 during use, and can also protect the lock body 10 in the case of bumping, dropping, etc., reducing the possibility of being damaged. A cover 3 that can be opened and automatically reset when released is installed at the first opening 201 of the shield 2 to cover the lock hole 11. When unlocking or locking is required, the cover 3 is rotated to expose the lock hole 11 in the first opening 201 for unlocking or locking. When the lock hole 11 does not need to be operated, the cover 3 can shield the lock hole 11, thereby reducing the probability of oxidation and rust of the metal contact 111 at the lock hole 11 and improving the service life of the passive electronic lock. In addition, the cover 3 is rotatably arranged relative to the shield 2, which can be more convenient for the user to pinch when unlocking, so as to open the opening and insert the key to unlock, and it is not easy to drop the hand midway, improving the user experience.
[0037] It should be noted that the cover 3 and the shield 2 can be rotatably connected by the connecting rotating rod 5 mentioned below, can be rotatably connected by a connecting hinge, or can be rotatably connected by one of the cover 3 or the shield 2 protruding from the other with a through hole in cooperation. The present disclosure does not limit this. The elastic member 4 can be a spring or a torsion spring. The present disclosure does not limit this. The rotatable connection end of the cover 3 and the shield 2 can be the same end as the connection end of the elastic member 4 or can be different ends. The present disclosure also does not limit this. When the elastic member 4 is a spring, the spring can be arranged at the other end of the cover 3 away from the rotatable connection with the shield 2, that is, one end of the cover 3 is rotatably connected to the shield 2, and the other end is connected to the shield 2 through the spring. When the cover 3 is rotated relative to the shield 2, as the cover 3 moves, the first opening 201 will gradually start to be exposed until the key can be inserted into the keyhole 11, and the rotation of the cover 3 can be stopped. At this time, the spring is gradually stretched. When the key unlocking or locking is completed, the cover 3 can be released. At this time, the spring will pull the cover 3 to reset and cover the first opening 201. When the elastic member 4 is a torsion spring, one end of the cover 3 is rotatably connected to the shield 2, and the torsion spring is also connected to this end. Specific embodiments will be described below.
[0038] Furthermore, as Figures 1 to 3 shown, the shield 2 can include a side wall 21 and a top wall 22. The side wall 21 encloses a receiving cavity for receiving the lock body 10. The first opening 201 is formed on one side of the side wall 21 for the lock body 10 to extend into the receiving cavity. The top wall 22 is connected to the edge of the side wall 21 and is disposed opposite to the first opening 201. The top wall 22 can abut against the side of the lock body 10 away from the keyhole 11 to prevent the lock body 10 from disengaging from the shield 2. Here, as Figure 7 shown, cavities can be formed inside the side wall 21, the top wall 22, and the cover 3. The cavities are filled with a heat-insulating member 7. By filling the heat-insulating member 7 inside the side wall 21, the top wall 22, and the cover 3, the lock body 1 can have the effect of being heat-resistant, avoiding damage to the lock body 1 caused by accidental high temperature and making it impossible to open. The heat-insulating member 7 can be filled foam or heat-insulating cotton. The present disclosure does not limit this. A single cavity or multiple spaced cavities can be formed inside the side wall 21, the top wall 22, and the cover 3. The side wall 21, the top wall 22, and the cover 3 can also be plate bodies with a multi-layer structure. The heat-insulating member 7 is located in the middle area. For example, the side wall 21, the top wall 22, and the cover 3 can all be three-layer structures, and the heat-insulating member 7 is located in the middle layer and is clamped on both sides. The present disclosure does not limit this.
[0039] Furthermore, as Figure 1 and Figure 2As shown, the lock body 1 may include a lock beam 12. The lock beam 12 is connected to one end of the lock body 1 away from the lock hole 11. A second opening 202 for the lock beam 12 to pass through is formed in the top wall 22. In this way, when the passive electronic lock is in the form of a padlock, the protective cover 2 can allow the lock beam 12 to pass through without affecting the protection of the lock body 1, and does not affect the opening and closing flexibility of the lock beam 12. In addition, when installing the protective cover 2, after the lock beam 12 passes through the second opening 202, the remaining part of the top wall 22 can also abut against the lock body 1, which can also prevent the lock body 1 from sliding out of the protective cover 2.
[0040] According to an embodiment of the present disclosure, as Figures 1 to 4 shown, a first connecting member 20 may be formed at the edge of the protective cover 2, and a second connecting member 30 opposite to the first connecting member 20 is formed on the cover body 3. The passive electronic lock further includes a rotating rod 5. One end of the rotating rod 5 is fixedly connected to one of the first connecting member 20 and the second connecting member 30, and the other end of the rotating rod 5 is rotatably connected to the other of the first connecting member 20 and the second connecting member 30. The elastic member 4 is a torsion spring. The torsion spring is sleeved on the rotating rod 5, and both ends of the torsion spring are respectively connected to the first connecting member 20 and the second connecting member 30.
[0041] The torsion spring can be fixedly connected to the first connecting member 20 and the second connecting member 30 first. Grooves for inserting the ends of the torsion spring can be provided on the first connecting member 20 and the second connecting member 30. When the rotating rod 5 is fixedly connected to the second connecting member 30 and rotatably connected to the first connecting member 20, a through hole can be provided on the first connecting member 20. One end of the rotating rod 5 can pass through the first connecting member 20 and the torsion spring and then be fixedly connected to the second connecting member 30 to complete the connection of the rotating rod 5 with the shield 2 and the cover body 3. The fixed connection can be welding, that is, the second connecting member 30 is a flat plate structure and the rotating rod 5 is directly welded to the second connecting member 30. It can also be that two mutually perpendicular through holes are provided on the second connecting member 30, and a through hole is also provided at one end of the rotating rod 5 close to the second connecting member 30. After the rotating rod 5 passes through one through hole, the through hole of the rotating rod 5 coincides with the other through hole on the second connecting member 30, and at this time, a pin shaft is driven in for fixation. It can also be that a threaded structure is provided at the end of the rotating rod 5 close to the second connecting member 30, and two nuts are screwed on the rotating rod 5 on both sides of the second connecting member 30. After the rotating rod 5 passes through the second connecting member 30, it is clamped and locked from both sides to hold the second connecting member 30. The present disclosure does not limit this. The torsion spring can also be sleeved on the rotating rod 5 and fixed to the second connecting member 30 after the rotating rod 5 is fixedly connected to the second connecting member 30, and then the first connecting member 20 is sleeved on the rotating rod 5 and fixed to the torsion spring. The present disclosure does not limit this. To prevent the rotating rod 5 from disengaging from the first connecting member 20, a limiting end can be formed at one end of the rotating rod 5 away from the second connecting member 30. After the rotating rod 5 passes through the first connecting member 20, the limiting end abuts against the first connecting member 20 to prevent the rotating rod 5 from disengaging from the first connecting member 20. Threads can also be provided at the end of the rotating rod 5 away from the second connecting member 30. First, the rotating rod 5 can be fixedly connected to the second connecting member 30, then passed through the first connecting member 20, and then a nut can be screwed tightly at the end of the rotating rod 5. In this way, when the cover body 3 is toggled, since the second connecting member 30 on the cover body 3 is fixedly connected to the rotating rod 5, the cover body 3 drives the rotating rod 5 to rotate relative to the first connecting member 20.
[0042] When the rotating rod 5 is fixedly connected to the first connecting member 20 and rotatably connected to the second connecting member 30, a through hole may be provided on the second connecting member 30. One end of the rotating rod 5 can pass through the second connecting member 30 and the torsion spring and then be fixedly connected to the first connecting member 20 to complete the connection between the rotating rod 5, the shield 2 and the cover body 3. The fixed connection can be welding, that is, the first connecting member 20 is a flat plate structure and the rotating rod 5 is directly welded to the first connecting member 20. It can also be that two mutually perpendicular through holes are provided on the first connecting member 20, and a through hole is also provided at one end of the rotating rod 5 close to the first connecting member 20. After the rotating rod 5 passes through one through hole, the through hole of the rotating rod 5 coincides with the other through hole on the first connecting member 20. At this time, a pin shaft is driven in for fixation. It can also be that a threaded structure is provided at the end of the rotating rod 5 close to the first connecting member 20. Two nuts are screwed on the rotating rod 5 on both sides of the first connecting member 20. After the rotating rod 5 passes through the first connecting member 20, it is clamped and locked from both sides to hold the first connecting member 20. The present disclosure does not limit this. The torsion spring can also be sleeved on the rotating rod 5 and fixed to the first connecting member 20 after the rotating rod 5 is fixedly connected to the first connecting member 20, and then the second connecting member 30 is sleeved on the rotating rod 5 and fixed to the torsion spring. The present disclosure does not limit this. In order to prevent the rotating rod 5 from disengaging from the second connecting member 30, a limiting end can be formed at one end of the rotating rod 5 away from the first connecting member 20. After the rotating rod 5 passes through the second connecting member 30, the limiting end abuts against the second connecting member 30 to prevent the rotating rod 5 from disengaging from the second connecting member 30. A thread can also be provided at the end of the rotating rod 5 away from the first connecting member 20. First, the rotating rod 5 can be fixedly connected to the first connecting member 20, then passed through the second connecting member 30, and then a nut can be screwed tightly at the end of the rotating rod 5. In this way, when the cover body 3 is toggled, since the first connecting member 20 on the shield 2 is fixed to the rotating rod 5, the cover body 3 rotates relative to the rotating rod 5.
[0043] Here, for the extending direction of the rotating rod 5, such as Figure 3As shown, the extending direction of the rotating rod 5 can be the thickness direction of the cover body 3. Since the side wall 21 extends from the top wall 22 to the first opening 201, which can also refer to the extending direction of the side wall 21 in the above text. In this case, the first connecting member 20 and the second connecting member 30 are spaced apart in the height direction of the cover body 3. At this time, when the cover body 3 is toggled, the cover body 3 will cover part of the first opening 201 and expose part of the first opening 201. The larger the toggling angle of the cover body 3, the less part of the first opening 201 is covered by the cover body 3, until the cover body 3 completely leaves the first opening 201 and the first opening 201 is completely opened and exposed. When the first opening 201 is opened, the keyhole 11 is exposed and the key can be inserted to unlock. After unlocking is completed, the cover body 3 is released. Under the action of the torsion spring, the torsion spring can drive the cover body 3 to gradually cover the first opening 201 until the cover body 3 is reset. The extending direction of the rotating rod 5 can also be the width direction of the cover body 3. In this case, the first connecting member 20 and the second connecting member 30 are spaced apart in the thickness direction of the cover body 3. At this time, when the cover body 3 is toggled, the cover body 3 is separated from the entire first opening 201, exposing the first opening 201. The larger the toggling angle of the cover body 3, the greater the distance between the same position on the cover body 3 and the first opening 201 compared to when the toggling angle is small. When the gap between the first opening 201 and the cover body 3 is large enough, the key can be inserted to unlock. After unlocking is completed, the cover body 3 is released. Under the action of the torsion spring, the torsion spring can drive the cover body 3 to gradually reduce the distance from the first opening 201 until the cover body 3 contacts and abuts against the shield 2, so that there is no gap between the cover body 3 and the first opening 201, enabling the cover body 3 to cover the first opening 201.
[0044] Furthermore, as Figure 2 shown, when the rotating rod 5 extends along the thickness direction of the cover body 3, the first opening 201 can be formed with a branch end 23 extending in a direction away from the lock body 10. The branch end 23 can limit the cover body 3 when the cover body 3 contacts the branch end 23, thereby preventing the problem that the cover body 3 is overly reset due to the inertia of the torsion spring, resulting in the cover body 3 rotating in the reverse direction and the cover body 3 being unable to completely cover the first opening 201.
[0045] According to an embodiment of the present disclosure, as Figure 1 、 Figure 2 and Figure 5As shown, the passive electronic lock may also include two limit members 6, which pass through the shield 2 and respectively abut against two opposite sides of the lock body 10. The function of the limit member 6 is to clamp the lock body 10 to limit the lock body 10, so as to prevent the lock body 10 from being displaced in the shield 2 and causing collision. With respect to the connection between the limit member 6 and the shield 2, the limit member 6 may be screwed onto the shield 2. The distance between the two limit members 6 may be adjusted by twisting the limit member 6 to accommodate lock bodies 10 of different sizes. A matching groove 61 may be provided on one side of the limit member 6 extending out of the shield 2 to match with a screwdriver or a wrench. The shape of the matching groove 61 may be a straight line, a cross or a hexagonal shape according to the shape of the screwdriver or the wrench, and the present disclosure does not limit this. In addition, the limiting member 6 can also be provided with limiting ends at both ends, which are respectively located inside and outside the protective cover 2, and a spring is mounted on the limiting member 6. The spring can be located inside the protective cover 2 and press against the inner wall of the protective cover 2 and the limiting end of the limiting member 6 inside the protective cover 2. Through the pressing force of the spring, the lock body 10 can be clamped from both sides.
[0046] According to one embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 6 As shown, a toggle block 31 extending in a direction away from the lock body 10 may be formed on one side of the cover body 3 away from the lock body 10. When the cover body 3 is too thin or the torsion of the torsion spring is too large, the cover body 3 can be easily moved by pinching the toggle block 31 to expose the lock hole 11 in the first opening 201, so as to facilitate unlocking with a key. A plurality of anti-skid pads 311 may also be arranged at intervals on the toggle block 31 to increase the friction force and make it easier to pinch the toggle block 31 to move the cover body 3. The anti-skid pad 311 may be made of rubber and may be bonded to the surface of the toggle block 31, may be bonded only to one side, or may be bonded to both sides, which is not limited in the present disclosure. The toggle block 31 may be rectangular or semicircular, which is also not limited in the present disclosure.
