DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] A lock body assembly and a smart lock provided by the utility model are described in detail below in conjunction with the embodiments.

[0028] See also Figures 1 to 3 , Figure 1 is an exploded schematic diagram of an embodiment of a lock body assembly of the present application; Figure 2 It is a partial cross-sectional schematic diagram of an embodiment of a lock body assembly of the present application; Figure 3 1 is a side view of an embodiment of a lock assembly of the present application. The present application provides a lock assembly 100. The lock assembly 100 includes a lock housing 10, a lock tongue 11, and a main control board 12. The lock tongue 11 is retractably connected to the lock housing 10 along a telescopic direction. The lock tongue 11 can extend out of the lock housing 10 along the telescopic direction to lock the lock assembly 100. The lock tongue 11 can be retracted into the lock housing 10 along the telescopic direction to unlock the lock assembly 100.

[0029] The lock tongue 11 is provided with a limit groove 111. The limit groove 111 is used to accommodate at least part of the toggle switch 121. The main control board 12 is arranged on the lock housing 10. For example, the main control board 12 is detachably connected to the lock housing 10. A toggle switch 121 is arranged on one side of the main control board 12 facing the lock tongue 11. The toggle switch 121 is a conventional component for those skilled in the art. The toggle switch 121 is at least partially located in the limit groove 111. The limit groove 111 moves with the lock tongue 11 and acts on the toggle switch 121 to switch the working state of the toggle switch 121, which is used to provide real-time feedback on the position of the lock tongue 11.

[0030] See also Figure 4 , Figure 4 This is a circuit diagram of an embodiment of the lock assembly of the present application. Figures 1 to 3 When the lock tongue 11 extends out of the lock housing 10 in the telescopic direction, the upper limit groove 111 of the lock tongue 11 acts on the toggle switch 121, and the toggle switch 121 feeds back the signal that the lock tongue 11 extends out of the lock housing 10 in the telescopic direction to the main control board 12, and obtains the current position of the lock tongue 11. When the lock tongue 11 retracts into the lock housing 10 in the telescopic direction, the upper limit groove 111 of the lock tongue 11 acts on the toggle switch 121, and the toggle switch 121 feeds back the signal that the lock tongue 11 retracts into the lock housing 10 in the telescopic direction to the main control board 12, and obtains the current position of the lock tongue 11. When the lock tongue 11 does not extend out of the lock housing 10 or retract into the lock housing 10 in the telescopic direction, the upper limit groove 111 of the lock tongue 11 does not act on the toggle switch 121, and no signal from the toggle switch 121 is fed back to the main control board 12, and at this time, the lock tongue 11 is in an abnormal position.

[0031] The lock tongue 11 is extended or retracted into the lock housing 10 along the telescopic direction and acts on the toggle switch 121 to switch the working state of the toggle switch 121. Therefore, the lock state of the lock tongue 11 can be intuitively fed back in real time through the working state of the toggle switch 121 through the above-mentioned limit groove 111 and the toggle switch 121, which can not only accurately feed back the current state of the lock tongue 11, but also reduce the power consumption of the lock state detection and feedback of the lock tongue 11, and the required parts cost and structural space are smaller. The working state of the above-mentioned toggle switch 121 can correspond to the three states of the lock tongue 11 being locked, unlocked and abnormal.

[0032] In some embodiments, the limiting groove 111 includes a limiting bottom wall 1111, a first limiting side wall 1112, and a second limiting side wall 1113. The first limiting side wall 1112 and the second limiting side wall 1113 are arranged on opposite sides of the limiting bottom wall 1111. The arrangement direction of the first limiting side wall 1112 and the second limiting side wall 1113 is the same as the extension direction of the locking tongue 11. The orthographic projections of one end of the first limiting side wall 1112 away from the limiting bottom wall 1111 and one end of the second limiting side wall 1113 away from the limiting bottom wall 1111 on the extension line of the limiting bottom wall 1111 are both located on the extension line of the limiting bottom wall 1111. As in this embodiment, the orthographic projection of one end of the first limiting side wall 1112 away from the limiting bottom wall 1111 on the extension line of the limiting bottom wall 1111 is located on the extension line of the left end of the limiting bottom wall 1111; the orthographic projection of one end of the second limiting side wall 1113 away from the limiting bottom wall 1111 on the extension line of the limiting bottom wall 1111 is located on the extension line of the right end of the limiting bottom wall 1111. The first limiting side wall 1112 and / or the second limiting side wall 1113 may be, but not limited to, in a straight line or arc shape. When the first limiting side wall 1112 and the second limiting side wall 1113 are both in a straight line, the limiting bottom wall 1111 is set at an obtuse angle with the first limiting side wall 1112, and the limiting bottom wall 1111 is set at an obtuse angle with the second limiting side wall 1113.

[0033] Wherein, both the first limiting side wall 1112 and the second limiting side wall 1113 can be releasably abutted against the toggle switch 121. When the lock tongue 11 extends out of the lock housing 10 along the telescopic direction, the second limiting side wall 1113 on the lock tongue 11 can act on the toggle switch 121. That is, the second limiting side wall 1113 on the lock tongue 11 abuts against the toggle switch 121, and at this time, the first limiting side wall 113 does not abut against the toggle switch 121. When the lock tongue 11 is retracted into the lock housing 10 along the telescopic direction, the first limiting side wall 1112 on the lock tongue 11 can act on the toggle switch 121. That is, the first limiting side wall 1112 on the lock tongue 11 abuts against the toggle switch 121, and at this time, the second limiting side wall 113 does not abut against the toggle switch 121. By the cooperation between the limiting bottom wall 1111, the first limiting side wall 1112 and the second limiting side wall 1113, it is ensured that the first limiting side wall 1112 and the second limiting side wall 1113 in the limiting groove 111 can act on the toggle switch 121, thereby improving the accuracy of the current state of the lock tongue 11.

[0034] Specifically, the first limiting side wall 1112 and the second limiting side wall 1113 are symmetrically arranged on opposite sides of the limiting bottom wall 1111. When the first limiting side wall 1112 and the second limiting side wall 1113 act on the toggle switch 121 respectively, the first limiting side wall 1112 and the second limiting side wall 1113 can ensure that the force acting on the toggle switch 121 is the same, which can improve the service life of the toggle switch 121.

[0035] Further, the limiting groove 111 includes one transition side wall (not shown in the figure) or two transition side walls. When the limiting groove 111 includes one transition side wall, the transition side wall can be arranged between one side of the limiting bottom wall 1111 and the first limiting side wall 1112; or, the transition side wall can be arranged between the other side of the limiting bottom wall 1111 and the second limiting side wall 1113. When the limiting groove 111 includes two transition side walls, one transition side wall is arranged at a position between the limiting bottom wall 1111 and the first limiting side wall 1112. The other transition side wall is arranged at a position between the limiting bottom wall 1111 and the second limiting side wall 1113. Regardless of whether the above-mentioned limiting groove 111 includes one, two or more transition side walls, it is sufficient as long as the first limiting side wall 1112 and the second limiting side wall 1113 can both releasably abut the toggle switch 121. Among them, other features of the limiting groove 111 except the first limiting side wall 1112 and the second limiting side wall 1113 can be determined according to actual needs and are not limited here.

[0036] In some embodiments, the lock tongue 11 is further provided with a locking groove 112. The locking groove 112 is spaced apart from the limiting groove 111. The locking groove 112 includes a first locking side wall 1121 and a second locking side wall 1122 that are arranged opposite to each other. The lock body assembly 100 also includes a thumbwheel 13. The thumbwheel 13 is releasably abutted against the first locking side wall 1121 and the second locking side wall 1122 that are arranged opposite to each other in the locking groove 112. The thumbwheel 13 can drive the lock tongue 11 to be telescopically connected to the lock housing 10 along the telescopic direction. The lock tongue 11 is converted into a linear telescopic motion along the telescopic direction by the rotational motion of the thumbwheel 13, thereby realizing the locking and unlocking of the lock tongue 11.

[0037] When the thumbwheel 13 abuts against the first locking side wall 1121 of the locking groove 112, the lock tongue 11 extends out of the lock housing 10 in the telescopic direction, and the thumbwheel 13 does not abut against the second locking side wall 1122. When the thumbwheel 13 abuts against the second locking side wall 1122 of the locking groove 112, the lock tongue 11 retracts into the lock housing 10 in the telescopic direction, and the thumbwheel 13 does not abut against the first locking side wall 1121. Through the above-mentioned matching relationship between the thumbwheel 13 and the first locking side wall 1121 and the second locking side wall 1122 in the locking groove 112, the stability of the lock tongue 11 extending out and retracting into the lock housing 10 in the telescopic direction is improved, thereby improving the safety of the lock body assembly 100.

[0038] See also Figure 6 and Figure 7 , Figure 6 It is a partial schematic diagram of the self-locking state of the lock body assembly of the present application; Figure 7 This is a partial schematic diagram of the lock assembly of the present application being unlocked in a self-locking state. Figures 1 to 3Specifically, when the thumbwheel 13 drives the lock tongue 11 to extend and lock, the lock tongue 11 forms a self-locking body that telescopes back and forth. When the lock tongue 11 moves to the self-locking state, it not only realizes the axial self-locking of the lock tongue 11, but also can resist high axial pressure impact, thereby improving the safety of the lock body assembly 100. When the lock tongue 11 is in the above-mentioned self-locking state, the lock tongue 11 can withstand an axial static pressure of more than 2KN. When the lock tongue 11 needs to be released from the self-locking state, the thumbwheel 13 needs to be rotated to a certain angle before the lock tongue 11 can be unlocked.

[0039] In some embodiments, the first locking side wall 1121 is provided with a first recessed portion 11211. The second locking side wall 1122 is provided with a second recessed portion 11221. The thumbwheel component 13 is releasably abutted against the first recessed portion 11211 and the second recessed portion 11221. The lock tongue 11 extends out of the lock housing 10 along the telescopic direction, and the thumbwheel component 13 abuts against the first recessed portion 11211, at which time the thumbwheel component 13 does not abut against the second recessed portion 11221. The lock tongue 11 is retracted into the lock housing 10 along the telescopic direction, and the thumbwheel component 13 abuts against the second recessed portion 11221, at which time the thumbwheel component 13 does not abut against the first recessed portion 11211. By providing a first recessed portion 11211 on the first locking side wall 1121 and a second recessed portion 11221 on the second locking side wall 1122 , the strength and stability of the dial member 13 abutting against the first locking side wall 1121 and the second locking side wall 1122 can be improved, thereby improving the safety of the lock body assembly 100 .

[0040] The above-mentioned dial wheel member 13 can be driven mechanically or electronically. Mechanical driving can be to drive the dial wheel member 13 to move by the knob member 14. Electronic driving can be to drive the dial wheel member 13 to move by the drive motor 15. The driving methods of the above-mentioned mechanical driving and electronic driving methods to drive the dial wheel member 13 will be described in detail below.

[0041] The mechanical drive is achieved by the user rotating the knob 14. In one embodiment, the lock body assembly 100 further includes a thumbwheel 13. The thumbwheel 13 includes a first thumbwheel portion 131 and a second thumbwheel portion 132. The first thumbwheel portion 131 of the thumbwheel 13 is releasably abutted against the lock tongue 11. The first thumbwheel portion 131 is releasably abutted against the first locking side wall 1121 and the second locking side wall 1122 of the locking groove 112. The lock body assembly 100 further includes a knob 14. The knob 14 penetrates the lock housing 10 and is detachable from the second thumbwheel portion 132. That is, the knob 14 is mounted on the second thumbwheel portion 132 through the lock housing 10. The knob 14 drives the second thumbwheel portion 132 and drives the first thumbwheel portion 131 to releasably abut against the lock tongue 11.

[0042] The user acts on the knob 14 clockwise, and the knob 14 acts on the second dial 132 clockwise, and the dial 13 moves clockwise. At this time, the first dial 131 acts on the lock tongue 11 in the clockwise direction, so that the lock tongue 11 extends out of the lock housing 10. The user acts on the knob 14 counterclockwise, and the knob 14 moves counterclockwise. At this time, the first dial 131 acts on the lock tongue 11 in the counterclockwise direction, so that the lock tongue 11 retracts into the lock housing 10. Through the cooperation between the knob 14 and the dial 13, not only can the lock tongue 11 be driven by the rotation of the dial 13 to rotate to a linear back and forth telescopic movement, so as to achieve the locking and unlocking of the lock tongue 11, but also mechanical drive is achieved. The first dial 131 and the second dial 132 are fixedly connected or detachably connected. As in this embodiment, the first dial 131 and the second dial 132 are integrally formed.

[0043] See also Figure 8 , Figure 8 yes Figure 3 The schematic diagram of the structure of AA is shown. Figures 1 to 7 Specifically, the knob member 14 includes a knob portion 141 and a rotating portion 142. The knob portion 141 is used for mechanical driving by the user. The rotating portion 142 passes through the lock housing 10 and is connected to the second dial portion 132. A rotating groove 1322 is provided in the second dial portion 132. The rotating portion 142 is at least partially located in the rotating groove 1322. The cross-sectional shapes of the rotating portion 142 and the rotating groove 1322 are both non-circular and mutually adapted, which can reduce the relative sliding between the rotating portion 142 and the second dial portion 132, and facilitate the rotating portion 142 to drive the dial member 13 to rotate. Among them, the fixing member 161 passes through the rotating groove 1322 and is connected to the rotating portion 142, locking the rotating portion 142 on the second dial portion 132. Through the cooperation of the knob portion 141, the rotating portion 142 and the rotating groove 1322, the stability of the dial member 13 rotating to drive the lock tongue 11 to move is improved, thereby improving the safety of the lock body assembly 100.

[0044] The electronic drive is realized by the drive motor 15. As in one embodiment, the lock body assembly 100 further includes a thumbwheel member 13. The lock body assembly 100 further includes a drive motor 15. The drive motor 15 provides a driving force for the movement of the thumbwheel member 13. The drive motor 15 drives the thumbwheel member 13 to rotate, so that the thumbwheel member 13 and the lock tongue 11 can be releasably abutted. Under the action of the drive motor 15, the thumbwheel member 13 and the lock tongue 13 can be in an abutting state or a non-abutting state. The electronic drive of the thumbwheel member 13 is realized by the cooperation between the drive motor 15 and the thumbwheel member 13.

[0045] The lock body assembly 100 may include a knob 14. Alternatively, the lock body assembly 100 may include a drive motor 15. Alternatively, the lock body assembly 100 may include both the knob 14 and the drive motor 15 to achieve mechanical or electronic co-driving of the dial wheel 13. As in the present embodiment, the lock body assembly 100 includes both the knob 14 and the drive motor 15, that is, the dial wheel 13 can achieve both mechanical and electronic driving, thereby achieving a mechatronic lock-on / off experience of the lock body assembly 100.

[0046] In some embodiments, a transmission assembly (not shown in the figure) may be provided between the drive motor 15 and the dial member 13. The drive motor 15 acts on the transmission assembly, and the transmission assembly acts on the dial member 13 to move, so that the dial member 13 and the lock tongue 11 are releasably abutted. The transmission assembly may be a gear transmission or a belt transmission, etc.

[0047] In a specific embodiment, the driving shaft of the driving motor 15 is provided with a gear 151. A rack 1321 is provided on the outer periphery of the dial member 13. The gear 151 and the rack 1321 are meshed. The driving motor 15 drives the gear 151 to mesh with the rack 1321, so that the dial member 13 and the lock tongue 11 can be releasably abutted. The driving motor 15, the gear 151 and the rack 1321 cooperate with each other to improve the rotation accuracy of the dial member 13.

[0048] In some existing lock body assemblies 100, the switch action of the lock tongue 11 adopts an electromechanical separation structure, that is, a clutch mechanism (not shown in the figure) is required to realize the switching between the electronic switch lock and the mechanical switch lock, so as to increase the user's switch lock operation steps. However, the above lock body assembly 100 not only needs to add a clutch mechanism, resulting in an increase in the number of parts and increased costs, but also has lower control accuracy. Therefore, in this embodiment, when the lock body assembly 100 includes both a knob member 14 and a drive motor 15, the drive motor 15 can be a reverse drive motor. The dial member 13 includes a first dial portion 131 and a second dial portion 132. The first dial portion 131 can be releasably abutted against the lock tongue 11. The lock body assembly 100 also includes a knob member 14. The knob member 14 drives the second dial portion 132 to drive the first dial portion 131 to rotate, and drives the second dial portion 132 to drive the gear 151 to rotate. That is, when the knob 14 drives the second dial 132 to drive the first dial 131 to rotate, the second dial 132 also drives the gear 151 to rotate. Therefore, the lock assembly 100 can be compatible with both mechanical drive and electronic drive integrated unlocking, which can provide a better unlocking experience for the lock assembly 100.

[0049] Specifically, the drive motor 15 uses a small-grade magnet with a weak magnetic pull, which satisfies the reduction gearbox to achieve forward and reverse drive. Therefore, the lock body assembly 100 can be compatible with electronic drive and mechanical drive at the same time, without the need to set up a separate clutch mechanism, meeting the mechatronics unlocking experience, achieving a smaller structural space, and a better unlocking experience.

[0050] See also Figures 1 to 8 , the present application provides a smart lock. The smart lock (not shown in the figure) includes the lock body assembly 100 described above. It should be noted that the lock body assembly 100 in this embodiment is the lock body assembly 100 described in the above embodiment, and its specific structure is not repeated here. The smart lock can provide real-time feedback on the switch lock state of the lock tongue 11 by using the limit groove 111 and the toggle switch 121. It can not only accurately feedback the current state of the lock tongue 11, but also reduce the power consumption of the switch lock state of the lock tongue 11, and the required parts cost and structural space are smaller.
