Technical Field
[0001] This utility model relates to the technical field of locks, and in particular to a padlock. Background Technology
[0002] With the advancement of technology, the application of electronic locks is becoming increasingly widespread. Chinese patent announcement numbers CN205654185U and CN206319719U disclose an electronic lock actuator, including a lock cylinder or lock body, a latch slidably installed in a radial hole of the lock cylinder or lock body, a locked element, a micro motor installed in an axial hole of the lock cylinder or lock body, a latch elastic element installed at the bottom of the radial hole of the lock cylinder or lock body, and a control circuit for controlling the operation of the micro motor; the output end of the micro motor is provided with an eccentric crank; the latch is provided with a drive groove with two side walls forming a left drive surface and a right drive surface, the eccentric crank is located in the drive groove of the latch, and the width of the drive groove is smaller than the maximum diameter of the eccentric crank's running trajectory; when unlocking, the micro motor drives the eccentric crank to perform an eccentric rotational motion, the eccentric crank moves the right drive surface of the latch's drive groove to the right and compresses the latch elastic element, causing the left end face of the latch to disengage from the locking notch of the locked element, thereby unlocking the lock cylinder or lock body. However, in practical use, it has been found that existing electronic locks only have this one unlocking method. When the electronic circuit suddenly malfunctions, it can cause great trouble for users. Therefore, there is an urgent need to develop a double-opening electronic lock that overcomes the above-mentioned shortcomings. Utility Model Content
[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a padlock.
[0004] The above-mentioned problems of this utility model are solved by the following technical solution: A padlock includes a housing having a mounting hole and a lock hole, and two hanging rings having two ends that extend into the mounting hole and the lock hole respectively. The first end of the hanging ring is fixedly connected to the mounting hole, and the second end extends into the lock hole and is locked or released by a locking structure inside the housing. The locking structure includes a drive motor and a locking block driven by the drive motor. The locking block is provided with a limiting part to constrain the second end of the hanging ring within the housing. An ejection structure is provided inside the housing below the lock hole. In the unlocked state, the ejection structure pushes the second end of the hanging ring out of the constraint range of the limiting part, and the second end of the hanging ring automatically disengages from the lock hole.
[0005] A further provision of the above technical solution is that the hanging ring is a steel rope.
[0006] A further provision of the above technical solution is that the drive motor is driven by the unlocking module, and the unlocking module controls the circuit board inside the housing to start the drive motor.
[0007] By adopting the above technical solution, electronic unlocking modules such as fingerprint, password or induction are supported. Users input commands through the fingerprint collection panel, the circuit board controls the drive motor to start, drives the lock block to move, and the unlocking response is rapid.
[0008] A further provision of the above technical solution is as follows: an eccentric block is provided at the output end of the drive motor, and a drive groove is provided on the locking block facing the eccentric block; the eccentric shaft on the eccentric block extends into the drive groove.
[0009] By adopting the above technical solution, the drive motor cooperates with the lock block drive groove through the eccentric shaft of the eccentric block to realize the linear movement of the lock block. It has high transmission efficiency and compact structure, ensuring that the limiting part accurately constrains or releases the hanging ring.
[0010] A further configuration of the above technical solution is as follows: the driving groove is a groove with two open end faces, and the groove wall on the side away from the second end of the two groove walls along the moving direction of the locking block is the driving wall. The eccentric block drives the driving wall so that the limiting part is away from the second end of the hanging ring.
[0011] By adopting the above technical solution, the drive groove adopts an end face opening design, and the force direction of the eccentric shaft drive wall is clear; the upper chamfer of the limiting groove cooperates with the inclined surface of the locking pin, which facilitates the smooth insertion or disengagement of the locking pin and reduces the risk of mechanical jamming.
[0012] A further provision of the above technical solution is that the limiting part is a limiting groove provided at the end of the locking block, and the second end of the hanging ring has a locking pin that can be constrained by the limiting groove.
[0013] By adopting the above technical solution and setting a locking pin with a special structure, a mechanical limit is formed by the structure of "small diameter section stuck into the limiting groove + large diameter section blocking below", which prevents accidental disengagement and makes the locking more secure.
[0014] A further configuration of the above technical solution is as follows: the ejector structure consists of an ejector head and a spring located below the ejector head; the lower end of the spring abuts against the baffle rib on the inner wall of the housing, and the upper end supports the ejector head.
[0015] A further provision of the above technical solution is that a reset component is provided on the side of the locking block opposite to the limiting part.
[0016] By adopting the above technical solution, the lock block can be automatically reset after unlocking through the reset component, and can be restored to the locked standby state without additional operation, thereby improving the stability of the lock for repeated use.
[0017] A further provision of the above technical solution is that a charging module is connected to the circuit board, and the charging port of the charging module is exposed to the outside of the housing.
[0018] By adopting the above technical solution, the lock is powered by a built-in battery and paired with an exposed Type-C charging module, making it convenient to charge at any time, avoiding lock failure due to power depletion, and improving battery life reliability.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts an elastic hanging ring that can be bent into a U-shape under external force. After the external force is removed, it can be reset with the help of its own elasticity. In the unlocked state, the push-out head below the lock hole pushes the second end of the hanging ring out of the limiting part under the action of the spring. Combined with the elastic reset ability of the steel rope hanging ring itself, the second end of the hanging ring can automatically disengage from the lock hole, realizing a continuous action of "one-click unlocking + automatic pop-out", without the need for manual pulling, thus improving the convenience of use for users.

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0029] like Figure 1-7 As shown, this embodiment discloses a padlock.
[0030] A padlock includes a housing having a mounting hole and a lock hole, and two hanging rings having two ends that extend into the mounting hole and the lock hole respectively. The first end of the hanging ring is fixedly connected to the mounting hole, and the second end extends into the lock hole and is locked or released by a locking structure inside the housing. The locking structure includes a drive motor and a locking block driven by the drive motor. The locking block is provided with a limiting part to constrain the second end of the hanging ring within the housing. An ejection structure is provided inside the housing below the lock hole. In the unlocked state, the ejection structure pushes the second end of the hanging ring out of the constraint range of the limiting part, and the second end of the hanging ring automatically disengages from the lock hole.
[0031] The above is the basic scheme of this embodiment.
[0032] Specific reference Figure 1 As shown, the outer shell 100 is a shell structure with a mounting hole 101 and a lock hole 102, and the mounting hole 101 and the lock hole 102 are arranged on the same side. The first end of the hanging ring 200 extends into the mounting hole 101 for fixation, and the second end can be dislodged and disposed in the lock hole 102.
[0033] A locking structure is provided inside the cavity of the outer casing 100 to lock the second end. In the locked state, the second end of the hanging ring 200 extends into the lock hole 102 and is limited by the limiting part on the locking block 300 inside the lock hole 102, so that the second end cannot be dislodged from the limiting part and thus cannot be withdrawn from the lock hole 102.
[0034] In the unlocked state, the limiting part separates from the second end, and the constraint on the second end disappears. At the same time, there is also an ejection structure inside the outer shell 100 located below the lock hole 102. The ejection structure pushes the second end toward the lock hole 102. With the help of the elasticity of the hanging ring 200 itself, the second end of the hanging ring 200 is automatically disengaged from the lock hole 102, thus completing the unlocking.
[0035] In this embodiment, an elastic hanging ring 200 is used. Specifically, the main structure of the hanging ring 200 is made of steel rope, and the outside can be covered with a plastic film or other structure. The steel rope can be bent under external force, so that the entire hanging ring 200 can be in a U-shape, with both the first end and the second end extending into the mounting hole 101 and the locking hole 102 arranged on the same side.
[0036] After the external force on the hanging ring 200 is removed, the ejector structure only needs to eject the second end a certain distance. The steel rope's own reset action can then cause the second end to exit from the lock hole 102 and unlock automatically. There is no need to manually pull the second end of the hanging ring 200 out of the lock hole 102, making the operation convenient.
[0037] In this embodiment, the drive motor 1 is driven by the unlocking module 3, which controls the circuit board 2 inside the housing 100 to start the drive motor 1.
[0038] In this embodiment, a fingerprint unlocking mode is adopted. That is, the fingerprint acquisition panel 3.1 of the unlocking module 3 is exposed in the window 103 of the housing, and the circuit board 2, the unlocking module 3, and the drive motor 1 are electrically connected. When the user inputs the correct fingerprint on the fingerprint acquisition panel 3.1, the circuit board 2 controls the drive motor 1 to start, thereby driving the lock block 300.
[0039] In other embodiments, the unlocking module 3 may also be an electronic module such as a password unlocking unit or a sensor unlocking unit.
[0040] A battery 5 is installed inside the casing to power the circuit. Furthermore, a charging module 4 is connected to the circuit board 2, and the charging port of the charging module 4 protrudes outside the casing 100, as detailed below. Figure 3 As shown.
[0041] Preferably, the charging module 4 is a Type C charging device used to charge the battery 5.
[0042] In this embodiment, the specific implementation of the drive motor 1 driving the lock block 300 is as follows: an eccentric block 400 is provided at the output end of the drive motor 1, and a drive groove 301 is provided on the lock block 300 facing the eccentric block 400; the eccentric shaft 410 on the eccentric block 400 extends into the drive groove 301.
[0043] When the drive motor 1 starts, it drives the eccentric block 400 to rotate, and the eccentric shaft 410 on the eccentric block 400 performs eccentric motion around the output shaft of the drive motor 1. When the eccentric shaft 410 rotates in the drive groove 301, it abuts against the groove wall of the drive groove 301, thereby driving the locking block 300 to move.
[0044] Specifically, in this embodiment, the drive groove 301 is a groove with two open ends, and the groove wall on the side away from the second end of the two groove walls along the moving direction of the locking block 300 is the drive wall 301.1. The eccentric block 400 drives the drive wall 301.1 so that the limiting part is away from the second end of the hanging ring 200.
[0045] Specific reference Figure 2As shown, in this embodiment, the lower end face of the drive groove 301 is open for inserting the eccentric block 400. The locking block 300 is a cuboid and extends in the direction from the mounting hole 101 to the locking hole 102.
[0046] When the eccentric block 400 drives the lock block 300 to move, that is, one side of the lock hole 102 or the mounting hole 101 moves, thereby limiting or moving away from the second end of the hanging ring 200.
[0047] In the two groove walls along the length of the drive groove 301, the side away from the second end is the drive wall 301.1. That is, the eccentric shaft 410 extends into the drive groove 301 and can contact the drive wall 301.1 and push the drive wall 301.1, thereby driving the lock block 300 away from the second end.
[0048] In the locked state, the locking part of the locking block 300 is located on the second end side, limiting the second end. At the same time, the eccentric shaft 410 contacts the drive wall 301.1, as detailed below. Figure 5 As shown. When the drive motor 1 starts, it drives the eccentric shaft 410 to rotate. During the eccentric motion, the eccentric shaft 410 pushes the drive wall 301.1 in the direction of the push towards the mounting hole 101, thereby causing the locking block 300 to move towards the mounting hole 101. The limiting part disengages from the side of the second end, and the constraint effect on the second end disappears. (Refer to...) Figure 6 As shown.
[0049] Preferably, in this embodiment, the limiting part is a limiting groove 302 provided at the end of the locking block 300, and the second end of the hanging ring 200 has a locking pin 210 that can be constrained by the limiting groove 302.
[0050] Specific reference Figure 1 and Figure 7 As shown, in this embodiment, the locking pin 210 is a rigid column fixed to the second end of the hanging ring 200, and the middle part of the column is provided with a small diameter section 211, which can be inserted into the limiting groove 302. The part located at the lower end of the small diameter section 211 is a large diameter section 212, and the diameter of the large diameter end is larger than the inner diameter of the limiting groove 302. When the small diameter section 211 is located in the limiting groove 302, the large diameter section 212 is located below the limiting groove 302 and cannot move upward through the limiting groove 302, thus it cannot be dislodged from the limiting part.
[0051] Preferably, in this embodiment, the limiting groove 302 is a semi-circular hole coaxial with the lock hole 102, and the other side of the locking pin 210 is constrained by the inner wall of the outer shell 100.
[0052] Furthermore, in this embodiment, the upper end of the limiting groove 302 is provided with a chamfer to form a flared opening, and the small diameter segment 211 and the large diameter segment 212 located at the top are connected by an inclined surface, which can cooperate with the chamfer.
[0053] In this embodiment, the ejection structure consists of an ejector head 6 and a spring 7 located below the ejector head 6; the lower end of the spring 7 abuts against the retaining rib 120 of the inner wall of the housing, and the upper end supports the ejector head 6.
[0054] Specific reference Figure 7 As shown, in this embodiment, a motor mounting position is formed inside the housing by a rib 110, and the motor 1 is placed inside the motor mounting position; and a baffle 120 extends from the side of the motor mounting position. The baffle 120 is located below the ejector structure and has a horizontal surface that can place the spring 7. The lower end of the spring 7 is placed on the baffle 120, and the upper end abuts against the lower end of the ejector head 6, thereby providing upward support to the ejector head 6.
[0055] When the locking pin 210 is inside the housing 100 and is limited by the limiting part, the locking pin 210 drives the ejector head 6 downward, and the spring 7 is compressed and deformed; when the constraint on the locking pin 210 is removed, the spring 7 returns to its original state, and the ejector head 6 is pushed upward, thereby pushing the locking pin 210 out from the side of the locking block 300.
[0056] In this embodiment, the locking block 300 is driven by the eccentric shaft 410 so that the limiting part is away from the locking pin 210. When the locking pin 210 needs to be locked, the locking block 300 automatically resets, so that the limiting part moves toward the locking pin 210. Specifically, a reset member 8 is provided on the side of the locking block 300 opposite to the limiting part.
[0057] When locking is required, the locking pin 210 is inserted into the lock hole 102. At this time, the drive motor 1 is started, and the drive motor 1 drives the eccentric block 400 to rotate, so that the eccentric shaft 410 moves away from the drive wall 301.1. Since the drive wall 301.1 is no longer pushed by the eccentric shaft 410, that is, the locking block 300 is not subjected to external force, the reset member 8 is reset, and the locking block 300 is pushed toward the locking pin 210, so that the limiting part limits the locking pin 210.
[0058] Preferably, in this embodiment, the reset element 8 is a reset spring 7.
[0059] The outer shell 100 has a sliding groove 104 formed inside by the rib 110. The reset member 8 and the locking block 300 are both located in the sliding groove 104. The sliding groove 104 is set with an opening on the side facing the locking pin 210, which can accommodate the extension of the limiting part. The reset member 8 is held against the inner wall of the sliding groove 104. The locking block 300 is provided with a spring 7 post 310. The reset member 8 is sleeved on the spring 7 post 310.
[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
