[0052] Example 1

[0053] The electronic lock in this embodiment is arranged on the first body and the second body, and is used for locking the first body and the second body. The electronic lock in this embodiment can be installed on a suitcase, the first body is the case body, and the second body is the case cover. Of course, the electronic lock in this embodiment is not limited to being used on suitcases, but can also be used on products such as tool boxes, suitcases, and lockers, and is used for locking the above products.

[0054] like Figures 1 to 9 As shown, in the first embodiment of the present application, the electronic lock includes components such as a lock housing 10, a lock tongue 20, a lock hook 30, a connecting rod 40, a locking device, and a control device.

[0055] In the present embodiment, the lock housing 10 is fixedly mounted on the first main body; the lock tongue 20 is movably mounted on the lock housing 10, specifically, is rotatably hinged on the lock housing 10; the lock hook 30 is mounted on the second main body, and the lock hook 30 and the lock tongue 20 have a locked position that cooperates with each other and an unlocked position that disengages from each other. In the locked position, the lock hook 30 hooks the lock tongue 20 to achieve the locking of the two; a connecting rod 40, one end of which is hinged with the lock tongue 20, and the other end is matched with a track provided on the lock housing 10, and the connecting rod 40 has a locked state that restricts the movement of the lock tongue 20 on the track, and an unlocked state that releases the movement restriction of the lock tongue 20; a locking device is mounted on the lock housing 10, and includes a movably arranged locking member; wherein the locking member has a first working position that cooperates with the connecting rod 40 so that the connecting rod 40 is in a locked state, and a second working position that is disengaged from the connecting rod 40 under the control of the control device of the electronic lock so that the connecting rod 40 is in an unlocked state.

[0056] Furthermore, the electronic lock in this embodiment is adopted, and the locking member can realize the locking of the lock hook 30 and the lock tongue 20 in the locked position through the connecting rod 40. When unlocking is required, the electronic lock, under the control of the control device, realizes the unlocking of the connecting rod 40 through the locking device, and then realizes the unlocking of the lock hook 30 and the lock tongue 20 in the locked position. The user can realize the separation of the lock hook 30 and the lock tongue 20. During the operation, the user only needs to operate the control device to unlock the electronic lock. Compared with the prior art method in which the user needs to slide the password dial, the operation process is simple, which improves the user experience.

[0057] Specifically, in this embodiment, the locking device includes an electromagnetic component 70, and the locking member is specifically an electromagnetic core 72 disposed in the electromagnetic component 70. The electromagnetic core 72 is separated from the connecting rod 40 under the electromagnetic driving force of the electromagnetic component 70, so that the connecting rod 40 is in an unlocked state. Specifically, the electromagnetic component 70 also includes an electromagnetic housing 71 mounted on the lock housing 10, an electromagnetic coil is disposed in the electromagnetic housing 71, and the electromagnetic core 72 is movably mounted on the electromagnetic housing 71.

[0058] The locking device in this embodiment also includes a locking reset member that cooperates with the locking member, specifically a reset spring 73 that cooperates with the electromagnetic core 72. The reset spring 73 has an elastic reset force that enables the electromagnetic core 72 to move from the second working position to the first working position. After losing the force of the electromagnetic component 70, the electromagnetic core 72 can be reset to the first working position under the action of the reset spring 73, and then can continue to cooperate with the connecting rod 40 to achieve locking, without the need for separate control, further simplifying the operation process.

[0059] See also Fig. 9 The track in this embodiment is specifically formed on the guide rail 50, and the guide rail 50 is fixedly mounted on the lock housing 10. Of course, the track can also be integrally formed on the lock housing 10, and its function can also be achieved.

[0060] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 as well as Fig. 9 Specifically, the track in this embodiment includes a first track for the connecting rod 40 to be in a locked state, a second track for the connecting rod 40 to be reset, and a third track reset to the first track position under the action of the lock hook 30. The electronic lock in this example also includes a spring 12 that drives the lock to be reset from the first track to the second track, and the connecting rod 40 is at least reset to the second track under the action of the spring 12. Then, the connecting rod 40 in this embodiment is driven by the locking member, the lock tongue 20 and the electromagnetic core 72 to switch on the above-mentioned track, thereby realizing the switching control between the locked state and the unlocked state.

[0061] Specifically, the lock tongue 20 in this embodiment is rotatably mounted on the lock housing 10 , and the electronic lock further includes a torsion spring 11 cooperating with the lock tongue 20 , and the torsion spring 11 applies a restoring force to the lock tongue 20 .

[0062] Combine the following Figures 1 to 9 The working process of the electronic lock in this embodiment is described. The lock hook 30 and the lock tongue 20 in the electronic lock of this embodiment are triggered by pressing. When the lock hook 30 is pressed in, it rotates and buckles with the lock tongue 20, and the lock tongue 20 is locked under the action of the connecting rod 40. When unlocking is required, the electronic lock gives a voltage to the electromagnetic component 70. When the electromagnetic component 70 is powered on, it sucks back the electromagnetic core 72. At this time, the electromagnetic core 72 loses the limiting contact with the connecting rod 40. Under the elastic force of the spring 12, the connecting rod 40 is pushed to the next section of the track to achieve unlocking. When the electronic lock is powered off, the electromagnetic core returns to its original position under the action of the reset spring 73, but at this time the connecting rod 40 has passed the limit of the electric iron core under the action of the spring 12, and the unlocking has been completed. After unlocking is completed, the lock hook 30 can be separated from the lock tongue 20 at any time, that is, the purpose of unlocking is achieved. When the user needs to lock again, the locking can be completed by directly covering the box. When the lock hook 30 is pressed into the lock tongue 20 again, the lock tongue 20 drives the connecting rod 40 to move along the track, and when the connecting rod 40 reaches the position of the electromagnetic core 72, the locking is completed. Repeat the above process. The whole process is simple to operate and has a good user experience.

[0063] For the electric control part of the electronic lock of this embodiment, the electronic lock in this example also includes a panel, on which at least two different position marks are set; a knob, on which an indication mark is set, which can be rotated around the panel so that the indication mark points to any position mark on the panel; a sensor, which is set corresponding to the indication mark and rotates with the rotation of the knob, and is used to obtain the rotation direction of the knob and the position information of the indication mark; wherein a switch is set on the control device, and the control device is used to control the locking device based on the rotation direction of the knob, the position of the indication mark and / or the state of the switch in different working modes. Furthermore, during the use of the electronic lock in this embodiment, the user only needs to operate the knob to achieve the locking and unlocking of the electronic lock, which further simplifies the user's operation. At the same time, compared with the form of fingerprint lock, it avoids the situation where the fingerprint of the fingerprint lock fails or is difficult to identify, and ensures the safety of the electronic lock. Now for the password lock, it can achieve quick unlocking and password setting, overcoming the cumbersome operation of the traditional password lock.

[0064] Example 2

[0065] like Figures 10 to 15 As shown, in the second embodiment of the electronic lock, compared with the first embodiment, the locking device in this embodiment includes a motor 61, a screw 62 that is transmission-matched with the motor 61, and a screw sleeve that is threadedly matched with the screw 62. The locking member is a movable pin 64 that is installed on the screw sleeve and moves with the movement of the screw sleeve. The movable pin 64 moves with the screw sleeve under the drive of the motor 61, so that the connecting rod 40 is in an unlocked state.

[0066] Preferably, the screw sleeve of this embodiment includes a plurality of clamp arms 63 that can be opened and closed, specifically including two clamp arms 63 separated in half, and a thread groove 631 is provided on the clamp arm 63, wherein the thread groove 631 forms a threaded hole that cooperates with the screw rod 62 when the two clamp arms 63 are closed.

[0067] In this embodiment, a guide groove is provided on the lock housing 10 , and the clamp arm 63 is movably sleeved in the guide groove. When the clamp arm 63 is partially extended out of the guide groove, the clamp arm 63 is opened, and when it is inserted into the guide groove, the clamp arm 63 is closed to form a threaded hole.

[0068] The above-mentioned locking device can solve the problem that the ordinary motor 61 cannot accurately control the number of rotations of the motor 61, thereby causing the position of the movable pin 64 to be unable to be accurately controlled. Therefore, the clamping arm 63 only needs to be given a running time for the motor 61 to return to the initial position, thereby ensuring the accuracy of each operation.

[0069] Combine the following Figures 10 to 15The working process of the electronic lock in this example is described. The locking device also includes a locking reset member that cooperates with the locking member, and the locking reset member has an elastic reset force that allows the locking member to move from the second working position to the first working position. The output end of the motor 61 is transmitted to the screw 62 through a reduction gear. The screw 62 cooperates with the clamp arm 63 on the screw sleeve, and the clamp arm 63 is provided with a corresponding thread groove 631, wherein the initial state of the clamp arm 63 is an open state. After the clamp arm 63 enters the guide groove, under the limiting effect of the guide groove, the clamp arm 63 is closed to form a threaded hole to clamp the screw 62. When the motor 61 is powered, the screw 62 rotates to drive the clamp arm 63 to move, and the clamp arm 63 drives the movable pin 64 to retract in turn. After the movable pin 64 retracts, the connecting rod 40 can fall back to complete the unlocking. When the screw 62 rotates to a certain position, the clamp arm 63 moves to the open position of the guide groove. Under the action of its own elastic force, the clamp arm 63 opens and is free from the action of the screw 62. The iron core drives the clamp arm 63 back along the guide groove under the action of the elastic reset member. At this time, the movable core is blocked by the connecting rod 40 and cannot be restored to the initial position. When the user opens the box, the connecting rod 40 retreats, and the movable pin 64 returns to the initial position, and the clamp arm 63 clamps the screw 62 again.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
