Description

[Technical field]

[0001] The present invention relates to padlocks, and in particular to electronic padlocks. [Background technology]

[0002] The conventional padlock 1 described in Patent Document 1 in FIG. 1 has a housing 11, a shackle 12 formed in a U-shape and movably attached to the housing 11, a pair of engagement arms 13 movably attached within the housing 11 and having spherical tips, and an actuation arm 14 that controls the distance between the pair of engagement arms 13.

[0003] The shackle 12 has a long arm portion 121 and a short arm portion 122. The long arm portion 121 and the short arm portion 122 each have an engagement groove 123 that opens facing each other and into which the spherical tip of the engagement arm 13 can be fitted.

[0004] The tip of the long arm portion 121 of the shackle 12 is always accommodated in the housing 11, and the relative movement of the shackle 12 with respect to the housing 11 switches between a locked state in which the tip of the short arm portion 122 is accommodated in the housing 11 and an open state in which the tip of the short arm portion 122 is exposed to the outside of the housing 11. In the locked state in which the tip of the short arm portion 122 is accommodated in the housing 11, the spherical tips of the pair of engagement arms 13 fit into engagement grooves 123 formed in the long arm portion 121 and the short arm portion 122, respectively, and the operating arm 14, which fits between the pair of engagement arms 13, restricts the distance between the pair of engagement arms 13 from decreasing, so that the relative movement of the shackle 12 with respect to the housing 11 is prevented by the pair of engagement arms 13.

[0005] In addition, for example, when a key is used to move the operating arm 14 away from between the pair of engagement arms 13, the operation of pulling the tip of the short arm portion 122 of the shackle 12 out of the housing 11 can be achieved by moving the pair of engagement arms 13 closer to each other due to the corresponding shape relationship between the engagement groove 123 and the spherical tip of the engagement arm 13.

[0006] However, as shown in FIG. 2, for example, when a thin metal plate 10 is inserted into the gap between the short arm portion 122 of the shackle 12 and the housing 11, the shape correspondence between the engagement groove 123 and the spherical tip of the engagement arm 13 causes the operating arm 14 to move back, bringing the pair of engagement arms 13 closer to each other, and pulling the tip of the short arm portion 122 of the shackle 12 out of the housing 11, thereby enabling unauthorized unlocking, so there is still room for improvement.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an electronic padlock according to the present invention will be described in detail with reference to the drawings.

[0014] Figures 3 to 5 show an embodiment of the electronic padlock of the present invention, and as shown, the electronic padlock comprises housing means 2, shackle means 3, locking means 4, control means 5, waterproofing means 6, and alarm means 7.

[0015] The housing means 2 has a housing body 21 and a cover member 22 which together enclose an accommodation space 20 , and a holding frame 23 which is attached between the housing body 21 and the cover member 22 and is positioned within the accommodation space 20 .

[0016] As shown in Figures 4 to 6, the housing main body 21 has a back plate 24, a peripheral wall 25 extending from the outer peripheral edge of the back plate 24 toward the front side (i.e., the lid member 22 side) along the thickness direction Y, a battery cover 26 that is detachably attached to the rear side of the back plate 24 (i.e., the opposite side to the lid member 22), and a rotating member 27 that is attached to the back plate 24.

[0017] As shown in Figures 5 and 7, the back plate 24 is formed to have two guide grooves 241 that are arranged apart from each other in the height direction Z and extend along the left-right direction X, a partition plate 242 that extends inward from the peripheral wall 25 and is separated from one of the guide grooves 241 in the height direction Z, a limiting block 243 on the opposite side of the partition plate 242 and separated from the other guide groove 241 in the height direction Z, and a battery mounting port 245 that connects the storage space 20 to the outside. In addition, a contact protrusion 244 that extends along the thickness direction Y next to the limiting block 243 (upper side in the figure), and an anti-slip member 246 that is formed in an approximately U-shape and is arranged on the side that does not face the storage space 20 are attached.

[0018] 4 and 5, a first shackle hole 251A is formed in a portion of the peripheral wall 25 above the limiting block 243 in the height direction Z, and a second shackle hole 251B is formed in a portion of the peripheral wall 25 above the partition plate 242. Both the first shackle hole 251A and the second shackle hole 251B are circular.

[0019] As shown in Figures 4, 5 and 8, the battery cover 26 has a cover body 261 that is detachably attached to the back plate 24, a fixing portion 262 that extends toward the storage space 20 at one end (the upper end in Figure 8) of the cover body 261, and a fixing groove 263 that is formed so as to open in the fixing portion 262 (towards the upward side in Figure 8).

[0020] The rotating member 27 has a rotating switch 272 that extends into the accommodation space 20 by inserting through the back plate 24 from outside the housing body 21 and is rotatably attached to the back plate 24, and a swinging part 271 that is attached to the rotating switch 272 in the accommodation space 20 and swings to be switched between an engagement position and a release position according to the rotation of the rotating switch 272. The swinging part 271 is formed to have a limiting surface 273 that faces the first shackle hole 251B side at the release position, and an engagement hook 274 formed on the opposite side of the limiting surface 273. Incidentally, in this embodiment, the tip of the rotating switch 272 that has been inserted through the back plate 24 of the housing body 21 engages with the rotating switch 272, and when the rotating switch 272 is operated to rotate relative to the back plate 24, the swinging part 271 that engages with the rotating switch 272 is switched between the engagement position and the release position accordingly.

[0021] As shown in Figures 5, 6 and 8, the cover member 22 is attached to the peripheral wall 25 of the housing body 21 and surrounds the storage space 20 together with the housing body 21, and has an opening 221 that communicates with the storage space 20.

[0022] The holding frame 23 arranged in the accommodation space 20 is capable of housing a battery, and is formed so as to surround a battery slot 232 that opens toward the battery cover 26, and a substantially cylindrical passage space 231.

[0023] 4, 5, 9, and 13, the shackle means 3 is formed to have a connecting arm 30, a first arm 31A extending from one end of the connecting arm 30 along the height direction Z and inserted into the accommodation space 20 via the first shackle hole 251A, and a second arm 31B extending from the other end of the connecting arm 30 along the height direction Z and inserted into the accommodation space 20 via the second shackle hole 251B and shorter than the first arm 31A, and the first arm 31A and the second arm 31B each have an engagement groove 311 recessed to face each other. Also, a recess 312 extending along the height direction Z and an annular groove 313 located on the tip side of the recess 312 are formed at the tip of the first arm 31A that is inserted into the accommodation space 20.

[0024] 9, the recess 312 abuts against the abutment protrusion 244 when the connecting arm 30 of the shackle means 3 approaches the housing means 2 to its limit, thereby determining the bottom dead center of the shackle means 3 when approaching the housing means 2. As shown in FIG. 13, the annular groove 313 abuts against the abutment protrusion 244 when the connecting arm 30 of the shackle means 3 moves away from the housing means 2 to its limit, thereby determining the top dead center of the shackle means 3 when moving away from the housing means 2.

[0025] The locking means 4 has two slide members 41 that slide toward / away from each other within the storage space 20 along the left-right direction X perpendicular to the height direction Z, a stopper 42 that is attached to the housing means 2 and moves along the height direction Z to enter between the two slide members 41 and prevent the two slide members 41 from approaching each other further, and a spring member 43 as a compression coil spring that is interposed between the two slide members 41 and continues to apply a spring force to the two slide members 41 to separate the two slide members 41 from each other.

[0026] As shown in FIGS. 5, 9 and 10, the engagement portions 411 of the two slide members 41 each have a first contact surface 414 facing the other slide member 41 side.

[0027] In addition, each of the two slide members 41 has an extension portion 412 formed next to the first abutment surface 414 of the engagement portion 411 in the height direction Z, which extends toward the other slide member 41 and has a second abutment surface 415 at its tip.

[0028] The extension portions 412 of the two slide members 41 each have a protrusion portion 413 that protrudes toward one of the guide grooves 241 and is fitted into that guide groove 241, so that the protrusion portion 413 and the entire slide member 41 can slide along the extension direction of the corresponding guide groove 241, i.e., the left-right direction X.

[0029] In addition, the first abutment surface 414 of the engagement portion 411 of one slide member 41 faces the second abutment surface 415 of the extension portion 412 of the other slide member 41 in the left-right direction, and further, the stopper 42 can enter between the first abutment surface 414 and the second abutment surface 415 of each of the two slide members 41, which face each other and are located on the opposite sides of the first shackle hole 251A and the second shackle hole 251B.

[0030] That is, as shown in FIG. 9, the slide member 41 on the left side of the figure has an extension portion 412 formed below the first abutment surface 414, and the slide member 41 on the right side of the figure has an extension portion 412 formed above the first abutment surface 414, so that a biasing member 43 is attached between the first abutment surface 414 of the left slide member 41 and the second abutment surface 415 at the tip of the extension portion 412 of the right slide member 41, and the stopper 42 can enter from below between the first abutment surface 414 of the right slide member 41 and the second abutment surface 415 at the tip of the extension portion 412 of the left slide member 41.

[0031] As shown in Figures 4, 5 and 11, the control means 5 is configured to have a motor 51 attached to the retaining frame 23 of the housing means 2, a valve rod 511 extending from the motor 51 along the height direction Z through the passing space 231 to the stopper 42 and controlling the movement of the stopper 42 along the height direction Z by driving the motor 51, a control module 52 signal-connected to the motor 51, a battery 53 providing operating power to the control module 52, and a fingerprint sensor 54 signal-connected to the control module 52.

[0032] The control module 52 may be configured, for example, using a printed circuit board, and has a receiver 521 used to receive the wireless unlock signal S1. The receiver 521 may be configured, for example, using Bluetooth (registered trademark) technology, but other wireless transmission and reception technologies may also be used. When the receiver 521 receives the wireless unlock signal S1, the control means 5 outputs an unlock signal S2 to the motor 51 to move the valve rod 511, thereby controlling the motor 51 to move the stopper 42 away from between the two slide members 41. This allows the two slide members 41 to approach each other against the biasing force applied by the biasing member 43 to move them away from each other, and when the shackle means 3 is pulled toward the side away from the housing means 2, the first arm 31A and the second arm 31B of the shackle means 3 can be switched to a release state in which the two slide members 41 are separated from the engagement groove 311, as shown in FIG. 12.

[0033] The battery 53 is attached into the battery slot 232 through the battery mounting port 245, and provides the power required for the operation of the control means 5. The battery 53 may be a non-rechargeable (primary) or rechargeable (secondary) battery.

[0034] The fingerprint sensor 54 has a sensor surface 541 exposed to the outside of the housing means 2, and the control module 52 outputs an unlock signal S2 to the motor 51 to move the valve rod 511 in accordance with the detection result of the fingerprint sensor 54.

[0035] The waterproofing means 6 includes a waterproof ring 61 disposed between the fingerprint sensor 54 and the control module 52 to prevent moisture from the fingerprint sensor 54 side from affecting the control module 52, and a waterproof plate 62 attached to the battery cover 26 so as to close the gap between the battery slot 232 and the battery cover 26 to prevent moisture from entering the area around the battery 53 from the battery cover 26 side.

[0036] The alarm means 7 is connected to the control module 52 via signals and configured to give notification by sound or vibration under the control of the control module 52, and in this embodiment, a buzzer is used as the alarm means 7. It can give notification when the remaining charge of the battery 53 is low. In addition, the alarm means 7 can provide a response indicating that the operation has been performed appropriately by emitting an appropriate notification sound or vibration when various operations are performed.

[0037] As shown in Figures 9, 12 and 13, the stopper 42 is driven by the valve rod 511 and can move along the height direction Z with respect to each slide member 41 between a locked state shown in Figure 9 and an released state shown in Figures 12 and 13.

[0038] As shown in Figures 9 and 10, in the locked state, the engagement grooves 311 formed in the first arm 31A and the second arm 31B of the shackle means 3 are positioned within the accommodating space 20, the engagement portions 411 of the two slide members 41 are fitted into the two engagement grooves 311, and the stopper 42 enters between the two slide members 41 to prevent the two slide members 41 from approaching each other, thereby maintaining the state in which the engagement portions 411 of the two slide members 41 are fitted into the engagement grooves 311 formed in the first arm 31A and the second arm 31B, respectively, and thus making it impossible for the shackle means 3 to move relative to the housing means 2.

[0039] In addition, in the locked state, the tip of the first arm 31A, which is inserted into the storage space 20 via the first shackle hole 251A, abuts against the limiting surface 273 of the swinging part 271, preventing the swinging of the swinging part 271 and holding it in the engaged position, so that the engagement hook 274 of the swinging part 271 remains fitted into the fixing groove 263 formed in the battery cover 26, making it impossible to remove the battery cover 26.

[0040] 5, 12 and 13, when the stopper 42 is released from between the two slide members 41, the two slide members 41 approach each other, and the engagement portions 411 of the two slide members 41 are released from the engagement grooves 311 formed in the first arm 31A and the second arm 31B of the shackle means 3, respectively, allowing the first arm 31A and the second arm 31B of the shackle means 3 to move relatively with respect to the housing means 2. In this released state, the first arm 31A moves upward in the height direction Z and leaves the limiting surface 273 of the swinging part 271, so that the swinging part 271 operated by the rotation switch 272 swings to a release position in which the engagement hook 274 leaves the fixing groove 263, and the battery cover 26 can be removed.

[0041] In this manner, in this embodiment of the present invention, only when the receiver 521 receives the wireless unlock signal S1 or obtains a correct detection result from the fingerprint sensor 54, the control module 52 outputs the unlock signal S2 to the motor 51 to move the valve rod 511, thereby moving the stopper 42 away from between the two slide members 41 and enabling the two slide members 41 to approach each other. Therefore, when the shackle means 3 is pulled away from the housing means 2, the first arm 31A and the second arm 31B of the shackle means 3 can be switched to a release state in which the two slide members 41 are separated from the engagement grooves 311, as shown in FIG. 12. Only when the tip of this first arm 31A leaves the limiting surface 273 of the swinging part 271, the swinging part 271 is driven by the rotation switch 272 to switch to the release position where the engagement hook 274 leaves the fixed groove 263, making it possible to remove the battery cover 26.Since the battery 53 cannot be replaced in the locked state in which relative movement of the shackle means 3 with respect to the housing means 2 is not possible, unauthorized unlocking that assumes that the battery 53, which is the power source, will be removed can be prevented.

[0042] To summarise the above, the electronic padlock of the present invention can provide the following effects.

[0043] First, in the locked state, the engagement grooves 311 formed in the first arm 31A and the second arm 31B of the shackle means 3 are positioned within the accommodating space 20, the engagement portions 411 of the two slide members 41 are fitted into the two engagement grooves 311, and the stopper 42 enters between the two slide members 41 to prevent the two slide members 41 from approaching each other, thereby maintaining the state in which the engagement portions 411 of the two slide members 41 are fitted into the engagement grooves 311 formed in the first arm 31A and the second arm 31B, respectively, and thus makes it impossible for the shackle means 3 to move relative to the housing means 2.

[0044] In addition, in the locked state, the tip of the first arm 31A, which is inserted into the storage space 20 via the first shackle hole 251A, abuts against the limiting surface 273 of the swinging part 271, preventing the swinging of the swinging part 271 and holding it in the engaged position, whereby the engaging hook 274 of the swinging part 271 remains fitted into the fixing groove 263 formed in the battery cover 26, making it impossible to remove the battery cover 26, and thus preventing unauthorized unlocking which assumes that the battery 53 will be removed.

[0045] Furthermore, by providing the waterproof ring 61 and the waterproof plate 62, the effect of moisture on the electrical components is suppressed, ensuring stable operation.

[0046] Furthermore, by providing the alarm means 7, support functions for improving convenience, such as providing an appropriate response to an operation or notifying an insufficient remaining charge of the battery 53, are further enhanced.

[0047] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the gist of the present invention. [Explanation of symbols]
