[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] Please refer to Figure 1 , Figure 2 and Figure 3 The contact padlock 100 includes a housing 1, an execution structure 3, a driving structure 5 and a control structure 7. The execution structure 3 includes a lock hook 31, a lock tongue 33 and a self-locking spring 35. The lock hook 31 is partially arranged outside the housing 1, the lock tongue 33 is arranged inside the housing 1 relative to the lock hook 31, and the self-locking spring 35 is arranged between the lock hook 31 and the housing 1. The lock hook 31 is provided with a notch 311 relative to the lock tongue 33. When one end of the lock tongue 33 abuts against the notch 311, the relative position of the lock hook 31 is fixed and cannot be moved, and the contact padlock 100 is in a locked state; the driving structure 5 is connected to the lock tongue 33, and the control structure 7 controls the working state of the driving structure 5, and drives the lock tongue 33 to move relative to the lock hook 31, thereby realizing unlocking.
[0013] In this embodiment, the control structure 7 includes an antenna 71, an energy storage capacitor 73 and a PCB board 75. The antenna 71 is attached to the housing 1 for receiving or sending wireless signals. The antenna 71 is connected to the energy storage capacitor 73. The energy storage capacitor 73 is arranged on the PCB board 75. The PCB board 75 is connected to the driving structure 5. By placing the contact charging device 200 close to the contact padlock 100, the contact padlock 100 can be charged and the identity can be recognized at the same time, thereby unlocking the padlock.
[0014] The device 200 can be a mobile electronic device such as a mobile phone, a watch or a bracelet. When the device 200 is close to the contact padlock 100, it cooperates with the antenna 71 to store electricity in the energy storage capacitor 73. When the PCB board 75 detects that the stored electricity reaches the preset requirement, a stable power supply is formed inside the contact padlock 100 to drive the driving structure 5. The contact padlock 100 can be controlled without setting an internal battery or connecting to an external power supply, which reduces the space structure and does not have power anxiety. Since users carry the device 200 such as a mobile phone, a watch or a bracelet with them in their daily lives, it will not bring additional inconvenience to the user, and there is no problem of losing the key required to unlock the lock, which is very convenient.
[0015] In this embodiment, there are two energy storage capacitors 73, and the voltage value to be reached is generally between 10V and 20V. The voltage regulator voltage in the PCB board 75 is generally controlled at 3V-5V. While providing sufficient voltage for the PCB board 75, energy storage can be achieved more quickly, shortening the unlocking time.
[0016] The housing 1 includes a top housing 11 and a bottom housing 12, wherein a first receiving cavity 101 and a second receiving cavity 102 are formed between the top housing 11 and the bottom housing 12, wherein the lock hook 31 is movably disposed in the first receiving cavity 101, and the drive structure 5 and the control structure 7 are disposed in the second receiving cavity 102. The housing 1 is in the shape of a disk as a whole, and a U-shaped notch 103 is disposed on one side of the housing 1. The top housing 11 cooperates with the bottom housing 12 to fix the positions of the structures, and the U-shaped notch 103 cooperates with the lock hook 31 to realize the switch function of the contact padlock 100, which is different from the existing arrangement in which the lock hook 31 protrudes from the housing 1 alone. The contact padlock 100 has a very compact structure, which is convenient for storage and can be applied to some scenes with a small installation area.
[0017] The driving structure 5 includes a motor 51, a first eccentric wheel 53, a rack 55 and a restoring spring 57. The motor 51 is connected to the PCB board 75, the first eccentric wheel 53 is arranged at one end of the motor 51, the rack 55 is connected to the lock tongue 33, the first eccentric wheel 53 abuts against the rack 55, and the restoring spring 57 is arranged between the housing 1 and the lock tongue 33. When the energy storage capacitor 73 reaches a preset voltage, the PCB board 75 confirms the unlocking through the antenna 71 and the device 200, and controls the motor 51 to rotate, and the motor 51 drives the first eccentric wheel 53 to rotate, thereby pushing the rack 55, the rack 55 and the lock tongue 33 move relative to the lock hook 31, and jointly squeeze the restoring spring 57 to unlock; when the user needs to lock, the restoring spring 57 will provide part of the thrust to promote the lock tongue 33 to return to the position of the locked state, saving the mechanical force required for locking.
[0018] In this embodiment, the driving structure 5 further includes a lock core 52, an unlocking rod 54, a second eccentric wheel 56 and a pull rod 58. One end of the lock core 52 is arranged through the housing 1, the unlocking rod 54 is connected to the lock core 52, the second eccentric wheel 56 is arranged at one end of the unlocking rod 54, the unlocking rod 54 is connected to the lock core 52, the pull rod 58 is connected to the rack 55 and the lock tongue 33, and the second eccentric wheel 56 abuts against the pull rod 58. The lock core 52 can be used for mechanical unlocking. The key is inserted into the lock core 52 and rotated. The second eccentric wheel 56 is driven to rotate by the rotation of the unlocking rod 54. The second eccentric wheel 56 pushes the pull rod 58. The pull rod 58 and the lock tongue 33 move relative to the lock hook 31 and jointly squeeze the restoring spring 57. The pull rod 58 and the rack 55 are both connected to the lock tongue 33 and can drive the lock tongue 33 to move relative to the lock hook 31. The lock cylinder 52, the unlocking rod 54, the second eccentric wheel 56 and the pull rod 58 can be used to unlock the lock in an original mechanical manner in case of an emergency, thereby providing a backup unlocking solution. The emergency includes but is not limited to the user forgetting to bring the device 200, or the device 200 is insufficient in power and cannot drive the contact padlock 100, or the internal circuit structure of the contact padlock 100 is damaged.
[0019] In this embodiment, the housing 1 further includes a waterproof lower cover 13, a waterproof upper cover 14 and a fixed cover 15. The waterproof lower cover 13 is disposed in the second receiving cavity 102; the waterproof upper cover 14 is fixedly connected to the waterproof lower cover 13, the PCB board 75, the energy storage capacitor 73 and the driving structure 5 are all disposed between the waterproof lower cover 13 and the waterproof upper cover 14; the fixed cover 15 is fixedly connected to the waterproof lower cover 13, and the motor 51, the rack 55, the first eccentric wheel 53, the second eccentric wheel 56, the unlocking rod 54, the pull rod 58 and part of the lock tongue 33 are disposed between the fixed cover 15 and the waterproof lower cover 13. During the unlocking process, the motor 51, the rack 55, the first eccentric wheel 53, the second eccentric wheel 56, the unlocking rod 54, the pull rod 58 and the lock tongue 33 will all move relative to the housing 1, and especially the motor 51 will vibrate strongly. By cooperating with the fixed cover 15 and the waterproof lower cover 13, the relative positions can be fixed to avoid positional displacement during the unlocking process. In addition, the waterproof lower cover 13 and the waterproof upper cover 14 are arranged in cooperation to protect the internal structure, thereby extending the service life of the contact padlock 100.
[0020] The contact padlock 100 further includes a waterproof pad 9, which is disposed at the connection between the lock tongue 33 and the waterproof upper cover 14 and the waterproof lower cover 13. Since the relative movement between the lock tongue 33 and the lock hook 31 is relatively frequent, the contact portion between the lock tongue 33 and the lock hook 31 is more likely to be infiltrated by water and dirt. By providing the waterproof pad 9, in cooperation with the lock tongue 33 and the recovery spring 57, the internal structure of the waterproof lower cover 13 and the waterproof upper cover 14 can be better protected. When the lock tongue 33 is locked, the recovery spring 57 can be used to make the lock tongue 33 press the waterproof pad 9, thereby providing waterproof protection. As long as the water pressure is less than the energy required to control the displacement of the recovery spring 57, the protection of the waterproof pad 9 cannot be broken, and the waterproof level of the contact padlock 100 can basically meet the requirements of IPX66.
[0021] It should be noted that the arrangement of the restoring spring 57 and the lock tongue 33 helps to enhance the anti-prying ability of the contact padlock 100. In the case of abnormal unlocking, the lock hook 31 is difficult to rotate to unlock due to the mutual contact between the notch 311 and the lock tongue 33 in the lock hook 31. When an external force violently strikes or hits, the vector direction of the impact force needs to be parallel to the expansion and contraction direction of the restoring spring 57, and the energy of the impact must completely deform and displace the restoring spring 57 to cause the lock tongue 33 to move. Both conditions are indispensable. The arrangement of the lock tongue 33, the lock hook 31 and the restoring spring 57 in the contact padlock 100 makes it difficult to achieve the above two situations at the same time. Therefore, the safety and reliability of the contact padlock 100 can be greatly improved.
[0022] In this embodiment, the shell 1 also includes a face cover 16 and a protective cover 17. The face cover 16 is arranged on one side of the top shell 11. The antenna 71 is clamped between the face cover 16 and the top shell 11 so that the antenna 71 and the device 200 can perform wireless signal transmission; the protective cover 17 is clamped between the top shell 11 and the bottom shell 12, and is attached to the lock core 52, which can cover the lock core 52. When the mechanical unlocking is not used, the lock core 52 is protected from dust or water pollution.
[0023] A slide groove 104 is further provided between the top shell 11 and the bottom shell 12, and the execution structure 3 further includes a slider 37, which is fixedly provided on one side of the lock hook 31 relative to the slide groove 104, and the contact padlock 100 can be put into a locked state by pushing the slider 37 to move relative to the slide groove 104.
[0024] Please also see Figure 4 The basic principle of the contact padlock 100 provided in this application is summarized as follows:
[0025] When the user uses the contact padlock 100 to lock, the user manually controls the slider 37 to drive the lock hook 31 to move along the slide groove 104 relative to the housing 1; until the notch 311 on the lock hook 31 moves to a position relative to the lock tongue 33, due to the force of the restoring spring 57, the lock tongue 33 is pushed to the notch 311 and engages with the lock hook 31, and the lock hook 31 cooperates with the U-shaped groove 103 to achieve locking.
[0026] When unlocking the device 200 through the outside, the user fits the device 200 against the cover 16 and approaches the antenna 71, and the energy storage capacitor 73 receives the electric energy transmitted by the antenna 71 and stores it; when the preset voltage is reached, the PCB board 75 is activated, and the antenna 71 is controlled to send an identity recognition signal to the device 200; after the device 200 receives the feedback signal and identifies and confirms it, it sends a control unlocking signal to the antenna 71, and after receiving the control signal, the PCB board 75 controls the motor 51 to rotate, thereby driving the lock tongue 33 to move; the lock hook 31 is affected by the self-locking spring 35, returns to the unlocked state position, and abuts against the lock tongue 33 again.
[0027] When unlocking the lock mechanically, the protective cover 17 is opened, and the key is inserted into the lock cylinder 52 and rotated, thereby driving the lock tongue 33 to move and unlock the lock.
[0028] In addition, it should be noted that, in this embodiment, the recess 311 fits the lock tongue 33 and has two planes perpendicular to each other. In the locked state, the lock tongue 33 will generate a locking force in the unlocking direction, making it difficult for the lock tongue 33 to move, thereby achieving a self-locking effect of the lock hook 31.
[0029] Compared with the prior art, the contact padlock 100 realizes wireless interaction with the external device 200 by arranging the antenna 71, the energy storage capacitor 73 and the PCB board 75 in the control structure 7, thereby realizing control over the lock hook 31 and the lock tongue 33. No battery is required to be arranged in the contact padlock 100. During use by the user, the switch control is realized by temporarily charging the antenna 71 in contact with the device 200, which not only reduces the volume of the contact padlock 100, but also solves the problem of charging and energy storage, making it more convenient to use.
[0030] Moreover, the arrangement of the lock tongue 33 and the lock hook 31 in the execution structure 3 and the driving structure 5 is simple and reasonable, and well combines wireless contact unlocking and mechanical backup unlocking, and has a compact structure; the engagement between the lock tongue 33 and the lock hook 31 cleverly uses the principle of mechanics, which not only ensures that the contact padlock 100 has high stability and reliability in the locked state, but also ensures smooth and labor-saving movement in the unlocked state.
[0031] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the protection scope of the present invention.
