Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically, it relates to an improvement of a padlock structure. Background Technology

[0002] Existing padlock structures, such as the Bluetooth smart padlock with patent publication number CN108590377B, propose a novel padlock structure, which includes a drive component and a cam. The cam is driven by the drive component to rotate around a rotation axis. Specifically, after receiving an unlock signal, the drive component drives the cam to rotate in one direction, and when receiving a lock signal, the drive component drives the cam to rotate in the opposite direction to reset.

[0003] Furthermore, the padlock structure in the patent document uses a rotating wheel and cam rotation mechanism. To achieve unlocking and locking reset, it also needs to be equipped with movable locking components, including a top pin and a steel column. At the same time, it also needs to be equipped with a second dust-collecting component and an electric contact component on the cam for engaging and resetting with the first magnetic component. The entire padlock structure has many components, and the action of opening and closing the lock is complex and cumbersome.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] This utility model addresses the aforementioned technical problems of existing padlocks by proposing a novel padlock structure that changes the mechanism of the rotating wheel and cam motion and simplifies the padlock structure.

[0006] To achieve the above-mentioned utility model / design objectives, the present utility model adopts the following technical solution:

[0007] A padlock, comprising:

[0008] Lock case body;

[0009] The drive unit is assembled inside the lock housing body;

[0010] The mounting component is assembled into the lock housing body, and a sliding portion is formed on its inner wall; and

[0011] A first limiting part is arranged circumferentially offset from the sliding part;

[0012] Second limiting part;

[0013] The rotating wheel is disposed within the mounting component and is connected to the drive device for transmission, and is capable of rotating under the drive device.

[0014] A cam is disposed within the mounting component, and a protrusion is formed thereon.

[0015] The locking bar is inserted into the main body of the lock housing;

[0016] An elastic element is arranged between the end of the lock beam and the lock housing body to eject the lock beam;

[0017] A rolling component, movable and at least partially disposed within the lock housing and mounting components, is used to lock or unlock the lock beam;

[0018] The elastic torsion member has one end connected to and abuts against the cam, and the other end connected to and abuts against the lock housing body;

[0019] When the padlock is unlocked, the drive device rotates and drives the rotating wheel to rotate. The rotating wheel drives the cam to rotate at a preset angle, causing the protrusion on the cam to slide into the sliding part and slide along the sliding part in the first direction. The rolling part moves towards the cam side, releasing the limit on the lock beam.

[0020] When the padlock is locked, the drive device rotates in the opposite direction, and the elastic torsion member applies force to the cam, causing it to move in the second direction. When it moves to the first limit part, it applies torsion force to the protrusion, causing it to lock onto the first limit part and the second limit part. The rolling member is pressed by the cam and moves towards the lock beam side.

[0021] When the padlock is in the locked state, the protrusion abuts against the first limiting part and the elastic torsion member applies an elastic force to the cam to limit the movement of the cam along the first direction. The protrusion abuts against the second limiting part to limit the rotation of the cam. The end face of the cam opposite to the rotating wheel abuts against and is fixed on the rotating wheel to limit the movement of the cam along the second direction. The rolling member abuts between the cam and the lock beam. The first direction and the second direction are opposite.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are:

[0023] The padlock proposed in this utility model is equipped with a drive device and a rotating wheel and a cam connected thereto. The rotating wheel and the cam abut against each other. When the rotating wheel rotates, it can drive the cam to move linearly along the mounting part. The locking and unlocking action is realized by cooperating with the rolling part. The entire padlock structure is simple and the locking and unlocking operation is convenient.

[0024] Meanwhile, the padlock proposed in this utility model is also provided with an installation component, in which a sliding part and a first limiting part are provided. This allows the padlock in the locked state to limit the upward movement of the cam by the top surface of the protrusion on the cam abutting against the bottom surface of the first limiting part. In addition, the elastic torsion member also applies a downward elastic force to limit the upward movement of the cam. The double limiting of the upward movement of the cam is achieved through the elastic torsion member and the first limiting part, ensuring that the cam will not automatically unlock due to the elastic force alone when subjected to external forces such as falling or vibration.

[0025] Meanwhile, when locked, the cam also limits its downward movement by abutting against the end face of the wheel opposite it, ensuring that the cam will not move downward and cause the padlock to fail when the padlock is dropped or vibrated.

[0026] Other features and advantages of this utility model will become clearer after reading the detailed embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0048] In some embodiments of this application, a padlock is proposed, comprising:

[0049] The lock housing body 100 constitutes the housing of the padlock, which is used to house the relevant components of the padlock.

[0050] When set up, the lock body 100 is configured as a square housing with an opening at the top.

[0051] Inside the lock housing body 100 are assembled a drive device 200, a rotating wheel 400 that is connected to the drive device 200, a cam 500 that cooperates with the rotating wheel 400, and a lock beam 610 inserted into the lock housing body 100.

[0052] When the locking bar 610 is extended, the padlock is in the unlocked state; when the locking bar 610 is inserted, the padlock is in the locked state.

[0053] The locking and unlocking of the locking beam 610 is achieved by the movable rolling component 700.

[0054] The rolling component 700 can be used to lock the locking beam 610 by clamping it between the outer side of the cam 500 and the locking beam 610;

[0055] And the locking beam 610 is unlocked by moving from the locking beam 610 to the cam 500 side.

[0056] In some embodiments of this application, the drive device 200 uses a drive motor with a reduction gear structure from the prior art to provide power to the padlock, and it is assembled inside the lock housing body 100.

[0057] To enable the assembly of the rotary wheel 400 and the cam 500, a mounting component 300 is also provided inside the lock housing body 100 and fixedly mounted thereon.

[0058] The mounting component 300 is a mounting insert, which forms a cavity inside and has a first opening at one end. The first opening is arranged downward when the padlock is in normal use.

[0059] A second opening is provided at the other end of the mounting component 300.

[0060] An annular step portion 110 is formed inside the cavity. During assembly, the rotating wheel 400 is assembled into the cavity through the first opening and is limited by the annular step portion 110.

[0061] The rotating wheel 400 is installed on the cavity side near the second opening.

[0062] A sliding portion 310 and a first limiting portion 320 and a second limiting portion 330 are formed on the inner wall of the cavity of the mounting component 300, which are offset from the sliding portion 310 in the circumferential direction at a certain angle.

[0063] In some embodiments of this application, a protrusion 510 is formed on the cam 500. The protrusion 510 is a sliding protrusion formed on the outer surface of the cam 500, which is used to slide with the sliding part 310 on the mounting component 300.

[0064] When the locking beam 610 is arranged, it is inserted into the lock housing body 100. The locking beam 610 includes a first locking beam leg 611 and a second locking beam leg 612. The length of the first locking beam leg 611 is greater than the length of the second locking beam leg 612.

[0065] The lock housing body 100 is provided with a first insertion blind hole 120 and a second insertion blind hole 130. The first lock beam leg 611 is inserted into the first insertion blind hole, and the second lock beam leg 612 is inserted into the second insertion blind hole.

[0066] An elastic element 620 is arranged between the end of the locking beam 610 and the lock housing body 100 for ejecting the locking beam 610.

[0067] Specifically, the elastic element 620 is a spring, which is arranged in the first insertion blind hole 120. A stop and limit part is provided on the first locking beam leg 611. One end of the elastic element 620 abuts against the stop and limit part, and the other end abuts against the inner wall of the first insertion blind hole 120.

[0068] The second insert leg is inserted into the second insert blind hole.

[0069] When the padlock is in the locked state, the first insert leg is inserted into the first insert blind hole and compresses the elastic element 620, and the second insert leg is inserted into the second insert blind hole.

[0070] A rolling component 700, movable and at least partially disposed within the lock housing and mounting component 300, is used to lock or unlock the lock beam 610.

[0071] The rolling component 700 has a first movable hole in the lock housing body 100 and a second movable hole in the mounting component 300. The rolling component 700 is arranged in the first movable hole and the second movable hole, wherein the first movable hole is connected to the first insertion blind hole.

[0072] A latch 614 is provided on the locking beam 610 for locking the rolling component 700.

[0073] When in the locked state, the rolling component 700 is partially inside the lock housing and mounting component 300, with its two sides protruding from the lock housing and mounting component 300. One side of the protruding part on each side abuts against the cam 500, and the other side is engaged with the latch 614, thus locking the lock beam 610.

[0074] When unlocking, the rolling component 700 moves from the latch 614 of the lock beam 610 to the cam 500 side and separates from the latch 614 of the lock beam 610, so that the lock beam 610 can automatically pop out under the elastic force of the compressed elastic element 620.

[0075] In some embodiments of this application, the padlock further includes: an elastic torsion member 630, one end of which is connected to and abuts against the cam 500, and the other end of which is connected to and abuts against the lock housing body 100.

[0076] The elastic torsion member 630 is an elastic torsion spring.

[0077] An installation groove is formed inside the cam 500. One end of the elastic torsion member 630 is inserted into the installation groove and connected to the wall of the installation groove. The other end of the elastic torsion member 630 extends out from the cam 500 and the second opening and is connected to the lock body 100.

[0078] When the padlock is in the locked state, the protrusion 510 abuts against the first limiting part 320 and the elastic torsion member 630 applies an elastic force to the cam 500 to limit the movement of the cam 500 along the first direction. The end face of the cam 500 opposite to the rotating wheel 400 abuts against and is fixed on the rotating wheel 400 to limit the movement of the cam 500 along the second direction. The rolling member 700 abuts between the cam 500 and the lock beam 610. The first direction and the second direction are opposite, wherein the first direction is the upward movement direction and the second direction is the downward movement direction.

[0079] In normal use, the padlock has the cam 500 positioned above the wheel 400, the drive unit 200 connected below the wheel 400, and the elastic torsion member 630 positioned above the cam 500. Therefore, when the padlock is locked, the elastic torsion member 630 not only applies a downward elastic pressing force to the cam 500 but also applies an elastic torsion force to the cam 500.

[0080] When the padlock is in the locked state, the top surface of the protrusion 510 abuts against the bottom surface of the first limiting part 320 to limit the upward movement of the cam 500. At the same time, the elastic torsion member 630 also applies a downward elastic force to limit the upward movement of the cam 500. The double limiting of the upward movement of the cam 500 is achieved by the elastic torsion member 630 and the first limiting part 320. This ensures that the cam 500 will not automatically unlock due to the elastic force alone when subjected to external forces such as falling or vibration.

[0081] Meanwhile, when locked, the cam 500 also limits its downward movement by abutting against the end face of the rotating wheel 400, which is opposite to it, ensuring that the cam 500 will not move downward and cause the padlock to fail when the padlock is dropped or vibrated.

[0082] When the padlock is unlocked, the drive device 200 rotates, causing the rotating wheel 400 to rotate. The rotating wheel 400 causes the cam 500 to rotate at a preset angle and separate from the first limiting part 320, so that the protrusion 510 on the cam 500 slides into the sliding part 310 and slides along the sliding part 310 in the first direction. The rolling part 700 moves towards the cam 500 side, releasing the limitation on the lock beam 610.

[0083] Since the protrusion 510 abuts against the bottom surface of the first limiting part 320, which is circumferentially offset from the sliding part 310, when unlocking, it is necessary to first release the first limiting part 320 from limiting the protrusion 510, and drive the cam 500 to rotate by a preset angle through the rotating wheel 400 so that the protrusion 510 and the first limiting part 320 are separated, and then enter the sliding part 310.

[0084] If the rotating wheel 400 is rotated again, the cam 500 will slide upward along the sliding part 310 under the limitation of the protrusion 510 and the sliding part 310. The upward sliding of the cam 500 changes the corresponding position of the rolling part 700 in the locked state, causing the rolling part 700 to move towards the cam 500. At this time, the limitation on the lock beam 610 is eliminated, and the lock beam 610 pops out to realize the unlocking.

[0085] When the padlock is locked, the drive device 200 rotates in the opposite direction, and the elastic torsion member 630 applies force to the cam 500, causing it to move in the second direction. When it moves to the first limiting part 320, it applies a torsional force to the protrusion 510, causing it to engage with the first limiting part 320 and the second limiting part 330. The rolling member 700 is pressed by the cam 500 and moves towards the lock beam 610.

[0086] When locking, the cam 500 needs to move from the unlocked position to the locked position. At this time, the drive device 200 needs to reverse, and the elastic torsion member 630 applies a downward elastic force to press the cam 500 downward. During the downward movement of the cam 500, a resistance is applied by the rotating wheel 400 that abuts against it to prevent it from sliding down quickly. As the cam 500 continues to move downward, it will squeeze the rolling member 700 and press the rolling member 700 into the slot 614 of the lock beam 610. At the same time, when the cam 500 moves to the position where its top surface is below the first limiting part 320, the protrusion 510 will twist and move a preset angle under the elastic torsion force of the elastic torsion member 630. When it receives the elastic torsion force, it is limited by the second limiting part 330, so that it rotates a preset angle, and its top is limited by the first limiting part 320.

[0087] In some embodiments of this application, the sliding part 310 includes a first slide section 311 and a second slide section 340 312 connected to each other. The first slide section 311 is disposed near the first opening, and the second slide section 340 312 is disposed near the second opening.

[0088] A second slide rail 340 is formed on the inner wall of the mounting component 300. The second slide rail 340 is located below the first slide rail section 311 and is offset from the first slide rail section 311 in the circumferential direction. The second slide rail 340 is smoothly connected to the first slide rail section 311 in the circumferential direction. The first limiting part 320 is formed at the junction of the second slide rail 340 and the first slide rail section 311.

[0089] When the second slide 340 is set, the depth of the second slide section 340 is greater than that of the first slide section 311, so that the locking step, i.e. the first limiting part 320, is formed at the joint of the first slide section 311 and the second slide 340.

[0090] When locking, the protrusion 510 initially slides down along the first slide section 311. As it slides down, the upper part of the protrusion 510 slides along the first slide section, and the lower part slides along the second slide section 340 312. At this time, the protrusion 510 is still limited by the first slide section 311 and will not rotate. After sliding until the top surface of the protrusion 510 is completely separated from the first slide section 311, the limitation on the protrusion 510 is eliminated, and the protrusion 510 will be twisted under the action of the elastic torsion member 630, smoothly rotating from the second slide section 340 312 to the position below the first limiting part 320 in the second slide section 340.

[0091] The protrusion 510 is located within the second slide rail 340 and its rotation angle is limited by the side wall of the second slide rail 340. The side wall of the second slide rail 340 constitutes the second limiting part 330.

[0092] In some embodiments of this application, the rotating wheel 400 has an abutting portion 410, and the cam 500 has an abutting mating portion 520 that mates with the abutting portion 410.

[0093] When the rotating wheel 400 rotates, it abuts against the abutting mating part 520 through the abutting part 410, which drives the cam 500 to rotate and move.

[0094] The abutting part 410 is an abutting protrusion formed on the rotating wheel 400, and the abutting mating part 520 is an abutting mating protrusion formed on the cam 500.

[0095] To ensure the smooth transmission between the two, two abutting parts 410 and two abutting protrusions 510 are provided, with the two abutting parts 410 cooperating with the two abutting protrusions 510 respectively.

[0096] In the arrangement, two insertion slots are formed between the two abutting parts 410, and two slots are also formed between the two abutting protrusions 510. The two abutting parts 410 are inserted into the two slots, and the two abutting protrusions 510 are inserted into the two insertion slots.

[0097] An abutting surface is formed on the abutting part 410, and an abutting mating surface that mates with the abutting surface is formed on the blocking mating part. The abutting surface is a spiral surface, and the blocking mating surface and its matching spiral surface are also formed.

[0098] When the rotating wheel 400 rotates, it can exert force on the abutting surface above to drive the cam 500 to rotate and separate from the first limiting part 320, and abut against the cam 500 to drive it to move up and down.

[0099] In some embodiments of this application, the cam 500 includes a cam 500 main body and a mating part 520 disposed on the cam 500 main body, a first cam 500 end face is formed on the cam 500 main body, and a second cam 500 end face is formed on the mating part 520.

[0100] The rotating wheel 400 includes a main body portion and an abutment portion 410 formed on the main body portion. A first end face of the rotating wheel 400 is provided on the main body portion, and a second end face of the rotating wheel 400 is formed on the abutment portion 410.

[0101] When the padlock is in the locked state, the end face of the first cam 500 abuts against the end face of the second rotating wheel 400, and the end face of the second cam 500 abuts against the end face of the first rotating wheel 400.

[0102] The downward movement of the cam 500 is limited by the first cam 500 end face and the second cam 500 end face respectively abutting against the second rotating wheel 400 end face and the first rotating wheel 400 end face, thus ensuring that the cam 500 will not move down and change position when locking.

[0103] In some embodiments of this application, the main body of the cam 500 includes:

[0104] The main body segment 531 and the unlocking segment 532 connected to the main body segment 531 have a receiving position 534 formed on the unlocking segment 532 that can accommodate at least a portion of the rolling member 700.

[0105] The main body section 531 is located above the stage section. When in the locked state, the main body section 531 and the rolling component 700 are in contact and engaged, and the rolling component 700 is pressed between the lock beam 610 and the main body section 531.

[0106] When unlocking, the cam 500 moves upward. At this time, the main body section 531 and the rolling component 700 separate, while the unlocking section 532 corresponds to the rolling component 700. Through the receiving position 534 provided on the unlocking section 532, the rolling component 700 can at least partially enter the receiving position 534, thereby separating it from the lock beam 610 and finally unlocking.

[0107] The accommodating position 534 can be an accommodating space or an accommodating slot formed on the unlocking section 532.

[0108] In some embodiments of this application, a downwardly inclined surface is formed on the unlocking segment 532. The setting of the inclined surface causes a corresponding receiving position 534 to be formed at the unlocking segment 532, so that the rolling member 700 can move to this position and abut against the inclined surface.

[0109] In some embodiments of this application, the lock beam 610 has a first end, and the elastic element 620 is disposed between the first end and the lock housing body 100.

[0110] And a second end, on which a magnetic element 810613 is provided.

[0111] The first end is located on the first locking beam leg 611, and the second end is located on the second locking beam leg 612.

[0112] Magnetic component 613 is a magnet.

[0113] In some embodiments of this application, the padlock further includes:

[0114] The main control board is located inside the lock housing body 100;

[0115] The electronic keypad 821 is electrically connected to the main control board and is used for user password input.

[0116] The locking beam 610 detection sensor is fixed on the main control board and is used to cooperate with the magnetic element 810613 to detect the insertion status of the locking beam 610;

[0117] The main control board controls the drive device 200 to unlock based on the signal received from the electronic keypad 821.

[0118] The main control board controls the drive device 200 to lock based on the signal received from the lock beam 610 detection sensor.

[0119] The locking beam 610 detection sensor can be a Hall sensor. When the locking beam 610 is inserted into the lock housing body 100, the magnetic element 613 at its second end approaches the locking beam 610 detection sensor. The locking beam 610 detection sensor can detect the magnetic element 613 and transmit a signal to the main control board. The main control board can control the drive device 200 to drive the rotating wheel 400 and the cam 500 to perform the locking action.

[0120] When unlocking, the user can enter a password through the electronic keypad 821. After the main control board receives the correct password, it controls the drive device 200 to drive the rotating wheel 400 and the cam 500 to unlock.

[0121] In some embodiments of this application, the padlock further includes:

[0122] The first detection component includes a first magnetic element 431 disposed on the rotating wheel 400 and a second magnetic element 432 arranged at a certain angle to the first magnetic element 431 in the circumferential direction of the rotating wheel 400.

[0123] During the arrangement, the first magnetic component 431 and the second magnetic component 432 are arranged at a 90-degree angle.

[0124] The first magnetic component 431 is the first magnet, and the second magnetic component 432 is the second magnet. Both the first magnetic component 431 and the second magnetic component 432 are embedded in the outer wall of the rotating wheel 400.

[0125] The first detection sensor 841 is used in conjunction with the first magnetic element 431 and the second magnetic element 432 to detect the position of the rotating wheel 400.

[0126] The first magnetic element 431 faces the magnetic pole of the first detection sensor 841, while the second magnetic element 432 faces the magnetic pole of the first detection sensor 841 in the opposite direction. Rotating the wheel 400 to different positions allows the different magnetic elements above it to correspond to the positions of the first detection sensor 841.

[0127] The second detection component includes:

[0128] A third magnetic element 540 is disposed on the cam 500;

[0129] And a second detection sensor 842, used in conjunction with the third magnetic component 540 to detect the position of the cam 500.

[0130] The third magnetic component 540, in conjunction with the second detection sensor 842, can be used to obtain the position of the cam 500.

[0131] The second detection component can work in conjunction with the first detection component to determine whether the switch lock is in position.

[0132] For example, when the padlock is in the locked state, the first magnetic component 431 and the first detection sensor 841 are in the same position, and the third magnetic component 540 and the second detection sensor 842 are in the same position. At this time, the main control board can receive the first signal from the first detection sensor 841 and the second signal from the second detection sensor 842 to know that the padlock is in the locked state.

[0133] When unlocking, the rotating wheel 400 rotates and changes position, so that the second magnetic component 432 above it corresponds to the position of the first detection sensor 841. At the same time, the cam 500 moves upward, so that the second detection sensor 842 above it separates from the third magnetic component 540. At this time, the first detection sensor 841 sends a third signal and the second detection sensor 842 sends a fourth signal. The main control board can determine that the padlock is in the unlocked state based on the third signal of the first detection sensor 841 and the fourth signal of the second detection sensor 842.

[0134] In some embodiments of this application, the padlock includes a silicone keyboard 822, on which a plurality of silicone buttons are provided, corresponding to the electronic buttons on the electronic keypad 821, and the plurality of silicone buttons protrude from the silicone keyboard 822.

[0135] Some embodiments of this application include:

[0136] The lock housing body 100 is provided with a stepped portion 110;

[0137] The cover plate 860 is provided with waterproof adhesive around its perimeter, and is fastened to the silicone keyboard 822 by the waterproof adhesive and the stepped portion 110.

[0138] A soft rubber shell is wrapped around the outside of the lock body 100. The soft rubber shell can be used for cushioning and shock absorption, and also plays a role in corrosion resistance.
