DETAILED DESCRIPTION

[0030] 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 in 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.

[0031] The preferred embodiment of the electronic padlock provided by the utility model is as follows: Figure 1 to Figure 2As shown, an electronic padlock includes a lock body 2 and a lock beam 1, wherein the lock beam 1 can be plugged into the lock body 2, and the lock body 2 includes: a body 21, a circuit control device 24 and a locking module 22, wherein the locking module 22 is correspondingly nested in the body 21, and a waterproof surface cover 23 is connected to the bottom of the body 21 to seal the entire locking module 22 to achieve a waterproof and drop-proof effect, and the circuit control device 24 is installed on the body 21, and the circuit control device 24 includes a control surface cover 241 and a control circuit board 242; wherein the control circuit board 242 is correspondingly nested inside the surface of the body 21 and is installed on the body 21 through the control surface cover 241.

[0032] like Figures 3 to 6 As shown, a plurality of locking grooves 11 are provided at intervals at both ends of the lock beam 1, and the output shaft ends of the upper locking pin 31 and the lower locking pin 32 can be respectively plugged into the corresponding locking grooves 11 at both ends of the lock beam 1. The locking module 22 comprises: a seat 220, a locking mechanism 3, an electronic drive device 4, and a mechanical lock core drive device 5. The locking mechanism 3, the electronic drive device 4, and the mechanical lock core drive device 5 are respectively installed in the seat 220 in a correspondingly nested manner. The circuit control device 24 is electrically connected to the electronic drive device 4, mainly by electrically connecting the control circuit board 242 to the motor 41 of the electronic drive device 4. The locking mechanism 3 comprises an upper locking pin 31 and a lower locking pin 32 movably mounted in the upper and lower positions. The output ends of the electronic drive device 4 and the mechanical lock core drive device 5 can each drive the upper locking pin 31 and the lower locking pin 32 to move in the unlocking direction or the locking direction. That is, the electronic drive device 4 and the mechanical lock core drive device 5 can separately drive the output shaft ends of the upper lock pin 31 and the lower lock pin 32 to disengage the locking groove 11 to realize the unlocking function, or drive the output shaft ends of the upper lock pin 31 and the lower lock pin 32 to be inserted into the locking groove 11 to realize the locking function.

[0033] like Figures 7 and 8 As shown, the upper locking pin 31 is provided with a first upper limit groove 311 and a second upper limit groove 312 , and the lower locking pin 32 is provided with a first lower limit groove 321 and a second lower limit groove 322 .

[0034] The locking mechanism 3 further includes an elastic member 33, which is respectively correspondingly nested in the upper locking pin 31 and the lower locking pin 32, and respectively correspondingly elastically abuts between the upper locking pin 31 and the seat body 220 and between the lower locking pin 32 and the seat body 220, so that the upper locking pin 31 and the lower locking pin 32 move along the locking direction. The elastic member 33 is a circular spring or an elastic structural member of a corresponding elastic material.

[0035] The electronic drive device 4 includes a motor 41 and a first rotating wheel 42, the first rotating wheel 42 is connected to the output shaft of the motor 41, and two symmetrically eccentrically arranged first rotating protrusions 43 are provided on the first rotating wheel 42. The two first rotating protrusions 43 are respectively and movably accommodated in the first lower limit groove 321 and the second upper limit groove 312, and the two first rotating protrusions 43 can abut against the side walls of the first lower limit groove 321 and the second upper limit groove 312.

[0036] Working principle in electronic lock function mode:

[0037] When unlocking: the user can input the password through the touch button on the control cover 241 or through fingerprint recognition or access control IC card recognition, and the control circuit board 242 analyzes and feeds back to the motor 41 to start, thereby driving the two first rotating protrusions 43 on the first rotating wheel 42 to rotate forward, one of the first rotating protrusions 43 abuts against the side wall of the first lower limit groove 321, directly driving the output shaft end of the lower locking pin 32 to overcome the elastic force of the elastic member 33 and correspondingly disengage from the locking groove 11; at the same time, the other first rotating protrusion 43 abuts against the side wall of the second upper limit groove 312, directly driving the output shaft end of the upper locking pin 31 to overcome the elastic force of the elastic member 33 and correspondingly disengage from the locking groove 11, and finally achieving overall unlocking.

[0038] After the lock body 2 is taken out after unlocking, the motor 41 is reversed and reset to the initial position, and the upper locking pin 31 and the lower locking pin 32 move to the initial position in the locking direction under the elastic force of the elastic member 33 .

[0039] When locking, just plug the corresponding lock beam 1 into the lock body 2. After the upper lock pin 31 and the lower lock pin 32 are contracted by the elastic force of the elastic member 33 under the extrusion of the lock beam 1, they extend and plug into the corresponding locking groove 11 to complete the locking.

[0040] like Figures 7 and 8 As shown, the mechanical lock core driving device 5 includes a mechanical lock core 51 and a second rotating wheel 52. The motor 41 and the mechanical lock core 51 are separately nested and installed in the seat body 220. The second rotating wheel 52 is connected to the output end of the mechanical lock core 51. The second rotating wheel 52 is provided with two symmetrically eccentrically arranged second rotating protrusions 53.

[0041] The two second rotating protrusions 53 are movably accommodated in the second lower limit groove 322 and the first upper limit groove 311 respectively and correspondingly, and the two second rotating protrusions 53 can abut against the groove side walls of the second lower limit groove 322 and the first upper limit groove 311.

[0042] Working principle in mechanical lock function mode:

[0043] When unlocking: the user can insert a key or other mechanical dial-type manual operation to rotate the mechanical lock core 51, thereby driving the two second rotating protrusions 53 on the second rotating wheel 52 to rotate forward, one of the second rotating protrusions 53 abuts against the side wall of the second lower limit groove 322, directly driving the output shaft end of the lower locking pin 32 to overcome the elastic force of the elastic member 33 and correspondingly disengage from the locking groove 11; at the same time, the other second rotating protrusion 53 abuts against the side wall of the first upper limit groove 311, directly driving the output shaft end of the upper locking pin 31 to overcome the elastic force of the elastic member 33 and correspondingly disengage from the locking groove 11, and finally achieving overall unlocking.

[0044] After the lock body 2 is taken out after unlocking, the upper lock pin 31 and the lower lock pin 32 move to the initial position in the locking direction under the elastic force of the elastic member 33, and the mechanical lock core 51 is reset to the initial position.

[0045] When locking, just plug the corresponding lock beam 1 into the lock body 2. After the upper lock pin 31 and the lower lock pin 32 are contracted by the elastic force of the elastic member 33 under the extrusion of the lock beam 1, they extend and plug into the corresponding locking groove 11 to complete the locking.

[0046] Moreover, the openings of the first upper limit slot 311, the second upper limit slot 312, the first lower limit slot 321 and the second lower limit slot 322 are all arranged and installed in the same direction, mainly because the slot openings of all the limit slots are arranged in the downward direction, which is convenient for their respective transmission and docking with the first rotating wheel 42 and the second rotating wheel 52, and the length of the openings of the first upper limit slot 311, the second upper limit slot 312, the first lower limit slot 321 and the second lower limit slot 322 along the unlocking direction is at least greater than the distance moved by the upper locking pin 31 and the lower locking pin 32 after being fully unlocked.

[0047] Specifically, when the movement is in the electronic lock mode, when unlocking, the first rotating wheel 42 rotates forward, and the two first rotating protrusions 43 drive the upper locking pin 31 and the lower locking pin 32 to move a certain distance in the unlocking direction, so that the output shaft ends of the upper locking pin 31 and the lower locking pin 32 can be withdrawn from the locking groove 11 to complete the unlocking. At this time, in order to prevent the second rotating wheel 52 from rotating, the utility model extends the second lower limit groove 322 and the first upper limit groove 311 by a certain distance in the unlocking direction, that is, the extension length of the second lower limit groove 322 and the first upper limit groove 311 is at least greater than the distance that the upper locking pin 31 and the lower locking pin 32 move after being fully unlocked, so that the side walls of the second lower limit groove 322 and the first upper limit groove 311 can be prevented from abutting against the two second rotating protrusions 53, so that when the first rotating wheel 42 rotates to unlock, the second rotating wheel 52 can remain stationary. When locking is required, the first rotating wheel 42 rotates in the opposite direction, and the upper locking pin 31 and the lower locking pin 32 move toward the opposite ends of the locking beam 1 and extend into the locking groove 11 under the elastic force of the elastic member 33 to complete the locking.

[0048] As above, when the movement is in the mechanical lock mode, when unlocking, the second rotating wheel 52 rotates forward, and the two second rotating protrusions 53 drive the upper locking pin 31 and the lower locking pin 32 to move a certain distance in the unlocking direction, so that the output shaft ends of the upper locking pin 31 and the lower locking pin 32 can be withdrawn from the locking groove 11 to complete the unlocking. At this time, in order to prevent the first rotating wheel 42 from rotating, the utility model extends the first lower limit groove 321 and the second upper limit groove 312 by a certain distance in the unlocking direction, that is, the extension length of the first lower limit groove 321 and the second upper limit groove 312 is at least greater than the distance that the upper locking pin 31 and the lower locking pin 32 move after being fully unlocked, so that the side walls of the first lower limit groove 321 and the second upper limit groove 312 can be prevented from abutting against the two first rotating protrusions 43, so that when the second rotating wheel 52 rotates to unlock, the first rotating wheel 42 can remain stationary. When locking is required, the second rotating wheel 52 rotates in the opposite direction, and the upper locking pin 31 and the lower locking pin 32 move toward the opposite ends of the locking beam 1 under the elastic force of the elastic member 33 and extend into the locking groove 11 to complete the locking.

[0049] It can be seen from the above unlocking and locking process that although the electronic drive device 4 and the mechanical lock core drive device 5 of the utility model are both connected to the locking structure 3, they are independent of each other. That is, the first rotating wheel 42 and the second rotating wheel 52 can drive the upper locking pin 31 and the lower locking pin 32 to move without affecting each other, so that the electronic lock and the mechanical lock can move independently, thereby ensuring that if one mode state fails, the other mode state can still be used normally, ensuring the stable operation of the overall structure.

[0050] like Figures 7 to 9 As shown, the seat body 220 includes a base 221 and a seat cover 222. The seat cover 222 encapsulates the locking mechanism 3, the electronic drive device 4 and the mechanical lock core drive device 5 in the base 221.

[0051] A transverse accommodating cavity 221a is provided in the base 221, the upper locking pin 31 is provided with an upper locking shoulder 313, and the lower locking pin 32 is provided with a lower locking shoulder 323. The elastic member 33 is firstly respectively mounted on the lower locking pin 32 and the upper locking pin 31, and then the lower locking pin 32 and the upper locking pin 31 are correspondingly movably assembled and nested in the transverse accommodating cavity 221a from bottom to top. Reset grooves 221b are provided on both sides of the transverse accommodating cavity 221a, and the elastic member 33 is respectively correspondingly abutted between the upper locking shoulder 313 and the reset groove 221b and between the lower locking shoulder 323 and the reset groove 221b, so that the lower locking pin 32 and the upper locking pin 31 can slide back and forth in the corresponding reset grooves 221b.

[0052] In order to prevent unnecessary rotational movement of the lower locking pin 32 and the upper locking pin 31 during the back-and-forth sliding process, a directional limit groove 221c is provided in the reset groove 221b, and guide protrusions 313a and guide protrusions 323a are provided on the upper locking shoulder 313 and the lower locking shoulder 323, and the guide protrusions 313a and guide protrusions 323a are correspondingly nested in the corresponding directional limit grooves 221c in their respective orientations, thereby effectively preventing the lower locking pin 32 and the upper locking pin 31 from rotating and reducing working losses.

[0053] The electronic padlock of the utility model integrates a locking mechanism, an electronic driving device and a mechanical lock core driving device into one through a locking module, realizes the integrated installation of the mechanical structure and the electronic structure module, and can realize the independent driving movement of the locking structure. The locking mechanism adopts an upper locking pin and a lower locking pin which are movably assembled in the upper and lower positions, and the upper and lower positions are compactly arranged and installed. Moreover, only the upper locking pin, the lower locking pin integrated elastic part and the base are adopted to realize the mechanism functions of unlocking and locking, which saves most of the parts and avoids the jamming of the parts during installation or use to cause damage, thereby improving the overall service life.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
