DETAILED DESCRIPTION

[0037] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0038] refer to Figures 1 to 15 As shown, the utility model discloses a lock reversing structure, comprising a lock body 1 and a movable device movably matched with the lock body 1;

[0039] The left and right sides of the lock body 1 are provided with latch holes 203, and the left and right sides of the movable device are provided with limit holes 33, and the spacing of the limit holes 33 is the same as the spacing of the latch holes 203;

[0040] The latch hole 203 is movably fitted with a latch 40 (the latch 40 is the pivot axis of the movable device) having one end that can be inserted into the limiting hole 33. A first spring 50 is sleeved on the latch 40 to enable the latch 40 to be separated from the limiting hole 33.

[0041] A limiting member 60 is disposed at the other end of the latch pin 40 , and the limiting member 60 is linked with the latch pin 40 to enable the latch pin 40 to be inserted into or out of the limiting hole 33 .

[0042] In a preferred embodiment, the above-mentioned limit member 60 is cooperated with a second spring 70 to enable it to disengage from the other end of the latch pin 40 and release the linkage with the latch pin 40; the back side of the lock body 1 is provided with mounting grooves 11 at positions corresponding to the two latch holes 203, and a reversing member 80 is detachably installed in the mounting groove 11 opposite to the latch pin 40. The reversing member 80 is relatively fixed to the lock body 1 and is provided with a push rod 801 that abuts against the limit member 60. The push rod 801 drives the limit member 60 to make it linked with the latch pin 40.

[0043] Through the above scheme, the utility model can realize the reversing function when the movable device cooperates with the lock body 1, so that the smart lock has stronger versatility. The user can choose to install the reversing member 80 in one of the installation grooves 11 of the lock body 1 according to actual needs, and push the limiting member 60 to compress the second spring 70 through the push rod 801 of the reversing member 80, and then link the latch 40 to compress the first spring 50, so that the latch 40 is inserted into the limiting hole 33 in the corresponding direction of the movable device, and this side of the movable device will be fixed relative to the lock body 1, that is, the side of the reversing member 80 that cooperates is the pivot side of the movable device. During the reversing process, the user only needs to simply disassemble and assemble the reversing member 80 to change its position, which is simple to operate and easy to use.

[0044] The following shows a specific embodiment of the present utility model, in which the above-mentioned lock reversing structure is applied to a smart lock, and the realization of the reversing function can be understood in combination with other structures of the smart lock.

[0045] The smart lock is provided with a handle hiding structure, which includes a lock body 1, a handle plate 2 and a handle driving mechanism; the handle plate 2 is movably fitted on the front side of the lock body 1 (i.e., the surface of the lock body 1 facing the user), and can cover most or all of the lock body 1, and one side of the handle plate 2 is pivotally fitted with the lock body 1 to form a pivot axis parallel to one side of the handle plate 2; the handle driving mechanism is installed in the lock body 1 and is transmitted to the handle plate 2, and is used to drive the handle plate 2 to open and close with the pivot axis as the axis, so that the handle groove a formed between the other side of the handle plate 2 and the lock body 1 can be opened and closed, when the handle plate 2 / handle groove a is in the open state, the user can insert his fingers into the handle groove a and hold the handle plate 2, thereby exerting force on the door leaf to push and pull the door leaf, and when the handle plate 2 / handle groove a is in the closed state, most or all of the lock body 1 is covered by the handle plate 2 to play an anti-theft role and make the appearance surface of the lock body 1 appear smooth. Therefore, the handle plate 2 is a covering part of the lock body 1, which can cover the lock body 1 to ensure the overall appearance of the lock. When the handle plate 2 is in a closed state, it can remain flat with the lock body 1 and is no longer an obvious protrusion on the surface of the lock body, thereby realizing the hiding of the traditional handle structure and eliminating safety risks such as bumps. When the handle plate 2 is in an open state, it can be used as a handle of the lock, providing a fulcrum for the user and the door leaf (or other furniture objects that need to be opened and closed) to facilitate the user to push and pull, thereby facilitating user use.

[0046] Furthermore, the handle plate 2 can be directly pivoted with the lock body 1 through a rotating shaft, so that the product has fewer accessories, but the processing and assembly accuracy of the accessories are higher. To this end, the utility model also includes an opening and closing member 3 that is relatively fixed to the handle plate 2 by means of screw b locking, snap connection, etc.; the opening and closing member 3 is arranged in a direction perpendicular to the side of the handle plate 2 and is transmission-connected with the handle drive mechanism, and one end of the opening and closing member 3 is relatively fixed to the lock body 1, and the other end of the opening and closing member 3 can rotate around one end of the opening and closing member 3 under the drive of the handle drive mechanism, thereby driving the handle plate 2 to open and close. By designing the opening and closing member 3, the handle plate 2 can be indirectly pivoted with the lock body 1, which is not easily affected by the processing accuracy of the accessories and is easier to assemble. Of course, the opening and closing member 3 can also be integrally formed on the inner side of the handle plate 2, so that it has a protruding part that can be transmission-connected with the handle drive mechanism.

[0047] The handle driving mechanism comprises a motor 4 electrically connected to the control part of the smart lock, a transmission shaft 5 drivingly connected to the motor 4, a first gear 6 coaxially connected to the end of the transmission shaft 5, a rack 7 drivingly connected to the first gear 6, and a connecting rod 8 pivotally connected to the opening and closing member 3 and the rack 7 at both ends; the rack 7 slides in the lock body 1 along a direction perpendicular to the side of the handle plate 2, see Figures 7 to 9, the linear motion of the rack 7 can be converted into the rotational motion of the other end of the opening and closing member 3 through the connecting rod 8. Therefore, the handle driving mechanism cooperates with the control part of the smart lock. When the user completes the identity recognition through electronic password, fingerprint, voiceprint, iris recognition, etc., the control part can control the motor 4 to rotate forward to open the handle plate 2 to automatically open the handle plate 2. When the handle plate 2 is opened and lasts for a period of time, or the door leaf is closed, the control part can also control the motor 4 to reverse and close the handle plate, and finally realize the automatic opening and closing of the handle plate 2. Of course, if the opening and closing member 3 is not provided in some embodiments, one end of the connecting rod 8 can be directly pivoted with the handle plate 2.

[0048] In some embodiments of the handle drive mechanism, the output shaft of the motor 4 is arranged in parallel with the transmission shaft 5, and a transmission connection is achieved between the two via at least two or more gears (i.e., a gear set) to transmit the torque of the motor 4 to the transmission shaft 5 and drive the transmission shaft 5 to rotate.

[0049] In some embodiments of the handle drive mechanism, the handle drive mechanism further includes a second gear 9 arranged in parallel with the first gear 6 and meshing with each other, and the thickness of the second gear 9 is greater than that of the first gear 6 so that the second gear 9 can also mesh with the rack 7, that is, the rack 7 is arranged in parallel at the end face of the first gear 6, and the first gear 6 and the rack 7 are respectively meshed with the second gear 9 to achieve a transmission connection between the first gear 6 and the rack 7. By setting the second gear 9 or even more gears, indirect transmission between the first gear 6 and the rack 7 can be achieved, so that the rack 7 does not directly mesh with the first gear 6, so that the rack 7 can be matched with the end face position of the first gear 6 instead of the circumferential surface position of the first gear 6, so that the corresponding thickness of this part can be reduced, and the thickness design of the lock can be reduced to meet the design requirements of some products.

[0050] Furthermore, the second gear 9 is installed in the lock body 1 through the gear fixing frame 10 to achieve relative fixation with the lock body 1 .

[0051] At the same time, the rack 7 is protruded from the middle of the side away from the first gear 6 to form a pivoting portion 71, the lower end of the connecting rod 8 is pivotally connected to the pivoting portion 71, and the opening and closing member 3 is movably connected to the top of the pivoting portion 71. By setting the pivoting portion 71, the opening and closing member 3 is connected to the side of the rack 7 instead of directly above it. When the handle plate 2 is in a closed state, the opening and closing member 3 can be folded to the side of the rack 7 instead of the upper surface. It can also reduce the thickness of the lock design, so that the accessories can be matched more compactly. In this embodiment, the opening and closing member 3 is a sheet metal part folded into a U shape, and is provided with a slot 31 for the connecting rod 8 to be embedded and pivotally connected, and the side of the slot 31 is provided with a clearance notch 32 for the pivoting portion 71.

[0052] In some embodiments of the handle driving mechanism, in order to facilitate installation and position limiting of accessories (especially the rack 7), the handle driving mechanism further includes a fixing seat 20 fixed to the lock body 1 by screw locking, snap connection, etc. The fixing seat 20 is provided with a movable opening 201 for the opening and closing member 3 to flexibly cooperate with; one end of the opening and closing member 3 is pivotally engaged with one end of the movable opening 201, that is, the above-mentioned pivot axis is formed between the opening and closing member 3 and the fixing seat 20; the rack 7 is slidably engaged between the fixing seat 20 and the lock body 1 to ensure the stability of its movement. Of course, since the fixing seat 20 is relatively fixed to the lock body 1, the fixing seat 20 can also be integrally formed on the lock body 1 under the premise that the process allows (it can form corresponding holes, grooves, cavities, etc. for installing accessories) and it is convenient for accessories to be installed; at the same time, since the opening and closing member 3 is relatively fixed to the handle plate 2 and the fixing seat 20 is relatively fixed to the lock body 1, the pivotal engagement between the handle plate 2 and the lock body 1 is finally achieved.

[0053] In some embodiments where the fixing seat 20 is provided, a plurality of balls 30 are matched on the surface of the rack 7 facing the fixing seat 20, and a ball groove 202 for the balls 30 to roll and match is provided in the fixing seat 20. The cooperation between the balls 30 and the ball groove 202 can reduce the friction between the rack 7 and the fixing seat 20, so that the rack 7 slides more smoothly, and can also limit the further movement of the rack 7 when the balls 30 roll to the end of the ball groove 202, so as to achieve the function of limiting.

[0054] In some embodiments in which a fixing seat 20 is provided, the reversing function is realized by cooperating with the reversing structure of the lock, specifically: the fixing seat 20 is relatively fixedly installed on the lock body 1; the movable device includes the handle plate 2 that cooperates with the lock body 1 in a flip-top manner, and the opening and closing member 3 that is relatively fixed to the handle plate 2; a movable opening 201 for the opening and closing member 3 to flexibly cooperate is provided in the fixing seat 20, and the above-mentioned latch hole 203 passes through the opposite side walls of the movable opening 201; the above-mentioned limiting holes 33 are provided at both ends of the opening and closing member 3, and when the opening and closing member 3 is folded into the movable opening 201, the two limiting holes 33 correspond to the two latch holes 203 one by one respectively; one end of the latch hole 203 is movably inserted into the movable opening The first spring 50 provides an elastic force to disengage one end of the latch pin 40 from the movable opening 201, thereby achieving the purpose of disengaging from the limiting hole 33; the limiting member 60 is movably engaged with the other end of the latch pin 40 to drive the latch pin 40 to compress the first spring 50 and insert it into the movable opening 201; the second spring 70 is arranged between the limiting member 60 and the fixing seat 20, and is used to provide an elastic force to disengage the limiting member 60 from the end position of the latch pin 40 and make the limiting member 60 abut against the lock body 1; the push rod 801 makes the limiting member 60 compress the second spring 70 and cooperate with the end position of the latch pin 40, thereby making the latch pin 40 insert into the movable opening 201 and the corresponding limiting hole 33.

[0055] In some embodiments with a reversing function, the above-mentioned limit member 60 is provided with an inserting portion 601 that penetrates into the pin hole 203, and a first inclined surface 602 is provided on the inserting portion 601. A second inclined surface 401 is provided at the corresponding end of the pin 40. The limit member 60 pushes the pin 40 through the sliding cooperation between the second inclined surface 401 and the first inclined surface 602.

[0056] In some embodiments with a reversing function, the lock body 1 is provided with a limiting groove 12 for the limiting member 60 to flexibly cooperate with, and the limiting groove 12 is connected to the mounting groove 11. If not resisted by the push rod 801, the limiting member 60 will be engaged in the limiting groove 12 under the elastic force of the second spring 70, so that the limiting member 60 is separated from the end position of the latch 40.

[0057] Furthermore, a through hole 13 for the push rod 801 to pass through is provided between the installation groove 11 and the limiting groove 12 .

[0058] In some embodiments with a reversing function, the above-mentioned pin hole 203 is located at the end of the end surface of the fixing seat 20 and is fixedly matched with a limiting cap 90 to prevent the pin 40 from falling out of the fixing seat 20 under the elastic force of the first spring 50, thereby playing a limiting role.

[0059] In some embodiments with a reversing function, the reversing member 80 is detachably installed in the mounting groove 11 by means of screw locking, snap connection, etc. The detachable connection method ensures that the reversing member 80 is relatively fixed to the lock body 1 so that the push rod 801 can push the limit member 60 to compress the second spring 70. At the same time, the reversing member 80 can be easily removed when the user needs to reverse.

[0060] In some embodiments with a reversing function, the reversing member 80 is provided with a limit rod 802, which can be used to limit the moving distance of the rack 7. Therefore, the length of the reversing member 80 needs to ensure that the limit rod 802 is on the moving track of the rack 7.

[0061] In some embodiments with a reversing function, a blocking member 100 is further included. The blocking member 100 and the reversing member 80 are respectively matched in two mounting grooves 11 of the lock body 1. The blocking member 100 covers the mounting grooves 11 to prevent foreign matter from entering the lock body 1.

[0062] Furthermore, a back plate 200 is provided on the back of the lock body 1, and the back plate 200 is provided with a movable hole 2001 for the reversing member 80 and the blocking member 100 to pass through. The back plate 200 can cover the accessories installed in the lock body 1 and does not affect the disassembly and assembly of the reversing member 80 and the blocking member 100.

[0063] In some embodiments of the above-mentioned handle driving mechanism, in order to make the opening and closing of the handle plate 2 more stable, both ends of the above-mentioned transmission shaft 5 are provided with opening and closing parts 3, a first gear 6, a rack 7 and a connecting rod 8 and other accessories, which are driven by the same motor 4. The power of the motor 4 can act on both ends of the handle plate 2 at the same time to achieve synchronous opening and closing movements at both ends of the handle plate 2.

[0064] See also Figure 8 In some embodiments of the above-mentioned handle driving mechanism, when the above-mentioned handle driving mechanism drives the handle plate 2 to the open state, the angle α formed between the axis of the connecting rod 8 and the axis of the rack 7 facing the opening and closing member 3 is an acute angle, thereby achieving the effect that: when the handle plate 2 is in the open state, if it is subjected to an external force other than the driving force of the motor, the external force acts on the handle plate 2 and is decomposed by the connecting rod 8, and the handle plate 2 cannot be moved in the closing direction, thereby preventing the safety risk of hands being pinched.

[0065] In some embodiments of the handle driving mechanism, the handle driving mechanism further comprises a rack limiting assembly; a convex shaft 72 is formed protruding from the middle of the side of the rack 7 away from the first gear 6 (which may be directly formed on the pivot portion 71); see Figure 8 and Fig. 9 The rack limit assembly includes a limit base 300, a swing rod 400, a movable plate 500 and a third spring 600; the limit base 300 is relatively fixed to the lock body 1; one end of the swing rod 400 is pivotally connected with the limit base 300, and the other end thereof is provided with a socket 4001 sleeved on the convex shaft 72; the movable plate 500 and the third spring 600 are both sleeved on the swing rod 400, and the movable plate 500 abuts against the convex shaft 72 under the elastic force of the third spring 600. When the rack 7 moves to the open position and the closed position, the motor 4 stops moving. At this time, the rack limit assembly can provide resistance through the movable plate 500 and the third spring 600 to prevent the rack 7 from shaking, thereby ensuring that the handle plate 2 does not shake, and is not easily driven by external force to "accidentally" open and close, thereby optimizing the user experience.

[0066] The above-mentioned handle hiding structure and lock reversing structure can be applied to various smart locks, such as electronic password locks, fingerprint locks, voiceprint locks and iris locks, etc., and have corresponding technical characteristics and technical effects.

[0067] The handle plate 2 is provided with a clearance hole 21, which corresponds to the clearance and installation of some functional devices of the lock, such as a lock core, a fingerprint module, etc.

[0068] The front side of the handle plate 2 is equipped with a control panel 700 of the smart lock for inputting passwords and other control operations.

[0069] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
