DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0026] In the related art, the door assembly has two modes: left opening and right opening. The left opening means that the right side of the door panel 20 is the rotation axis and it is opened from the left side. The right opening means that the left side of the door panel 20 is the rotation axis and it is opened from the right side. Figure 1 and Figure 2 As shown, when the door assembly is a left-opening door, the lock needs to be installed on the left side of the door panel 20. At this time, the lock tongue portion 30 of the lock extends or retracts from the left side of the door panel 20, thereby realizing the lock of the door panel 20. Figure 1 As shown, the operating member 10 of the lock has an ON position and an OFF position. When the operating member 10 is in the ON position, the bolt portion 30 is in the retracted position. At this time, the door panel 20 is in an unlocked state, so that the door panel 20 can be opened freely. When the operating member 10 is in the OFF position, the bolt portion 30 is in the extended position. At this time, the door panel 20 is in a locked state, so that the door panel 20 is locked and cannot be opened. Figure 1 and Figure 2 In the embodiment of the present invention, the operating member 10 is rotated in the counterclockwise direction, so that the operating member 10 can be switched from the ON position to the OFF position, thereby locking the door panel 20. At this time, the screwing direction of the operating member 10 is consistent with the extension direction of the lock tongue portion 30. However, if the lock is applied to Figure 3 In the right-opening door body assembly shown, the extension direction of the lock tongue portion 30 is opposite to the rotation direction of the operating member 10. Therefore, when the lock in the related art is on the left or right side of the door panel 20, the rotation direction of the operating member 10 for opening or closing the door is inconsistent, which can easily cause the user to operate incorrectly, thereby making the lock poor in performance.

[0027] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 4 to 22 As shown, the embodiment of the present utility model discloses a lock 100 , and the disclosed lock 100 includes a lock housing 110 , a locking tongue portion 120 and an operating member 130 .

[0029] The lock housing 110 provides a mounting base for other components of the lock 100. The lock housing 110 is provided with a mounting hole 111, and the operating member 130 can be mounted in the mounting hole 111 and connected to the lock tongue portion 120. The operating member 130 here is a component manually operated by a user, such as a knob, a lock core, etc. The operating member 130 can rotate around one of the axes of the mounting hole 111, and at this time, the operating member 130 can rotate in the mounting hole 111. Here, the central axis of the operating member 130 can coincide with the central axis of the mounting hole 111, so the operating member 130 can rotate around the central axis of the mounting hole 111.

[0030] The operating member 130 can drive the lock tongue portion 120 to switch between the retracted position and the extended position during the rotation process. The retracted position here refers to the position where the lock tongue portion 120 is unlocked from the door frame. At this time, the lock 100 is in an unlocked state, and the door panel 200 connected to the lock 100 can be opened freely. The extended position refers to the position where the lock tongue portion 120 is locked with the door panel 200. At this time, the lock 100 is in a locked state, and the door panel 200 connected to the lock 100 is locked and cannot be opened freely. At this time, the operating member 130 can switch between the unlocked and locked states.

[0031] The lock housing 110 has a first side 112 and a second side 113 disposed opposite to each other. Optionally, the first side 112 may be a side facing the left side of the door panel 200, and the second side 113 may be a side facing the right side of the door panel 200. Alternatively, the first side 112 may be a side facing the right side of the door panel 200, and the second side 113 may be a side facing the left side of the door panel 200. The specific positions of the first side 112 and the second side 113 are not limited herein.

[0032] The operating member 130 has an unlocking position, a first locking position, and a second locking position. Figures 4 to 7 As shown, the ON position is the unlocking position, the OFF1 position is the first locking position, and the OFF2 position is the second locking position.

[0033] When the operating member 130 rotates from the unlocked position along the first rotation direction to the first locked position, the operating member 130 drives the bolt portion 120 to extend from the first side 112 of the lock housing 110 to the extended position. When the operating member 130 rotates from the first locked position along the second rotation direction to the unlocked position, the operating member 130 drives the bolt portion 120 to retract from the first side 112 of the lock housing 110 to the retracted position. The first rotation direction here is the direction of rotation toward the first side 112, and the second rotation direction is the direction of rotation toward the second side 113. Since the first side 112 and the second side 113 are arranged opposite to each other, the directions in which the operating member 130 rotates toward the first side 112 and the second side 113 are opposite, so the first rotation direction and the second rotation direction are opposite.

[0034] Specifically, when the operating member 130 is switched from the unlocked position to the first locked position, the operating member 130 rotates toward the first side 112, and the bolt portion 120 also extends from the first side 112, so the extension direction of the bolt portion 120 is consistent with the rotation direction of the operating member 130. Similarly, when the operating member 130 is switched from the first locked position to the unlocked position, the operating member 130 rotates toward the second side 113, and the bolt portion 120 also retracts from the first side 112, so the retraction direction of the bolt portion 120 is also consistent with the rotation direction of the operating member 130. Here, the rotation direction of the operating member 130 switching from the unlocked position to the first locked position is opposite to that of the first locked position to the unlocked position, and the rotation angle is the same.

[0035] When the operating member 130 is rotated from the unlocked position to the second locked position along the second rotation direction, the operating member 130 drives the lock tongue portion 120 to extend from the second side 113 of the lock housing 110 to the extended position; when the operating member 130 is rotated from the second locked position to the unlocked position along the first rotation direction, the operating member 130 drives the lock tongue portion 120 to retract from the second side 113 of the lock housing 110 to the retracted position.

[0036] Specifically, when the operating member 130 is switched from the unlocked position to the second locked position, the operating member 130 rotates toward the second side 113, and the bolt portion 120 also extends from the second side 113, so the extension direction of the bolt portion 120 is consistent with the rotation direction of the operating member 130. Similarly, when the operating member 130 is switched from the second locked position to the unlocked position, the operating member 130 rotates toward the first side 112, and the bolt portion 120 also retracts from the second side 113, so the retraction direction of the bolt portion 120 is also consistent with the rotation direction of the operating member 130. Here, the rotation direction of the operating member 130 switching from the unlocked position to the second locked position is opposite to that of the second locked position to the unlocked position, and the rotation angle is the same.

[0037] In one solution, the lock 100 is arranged on the left side of the door panel 200, and the door panel 200 assembly is a case where the door opens to the left. The first side 112 mentioned above can be the left side of the lock 100, and the second side 113 can be the right side of the lock 100. The left side of the lock 100 is consistent with the left side of the door panel 200. At this time, OFF1 is the first locked position, that is, when the operating member 130 rotates toward the left side of the door panel 200, the lock tongue portion 120 extends from the right side to the left side of the door panel 200. When the operating member 130 rotates toward the right side of the door panel 200, the lock tongue portion 120 retracts from the left side to the right side of the door panel 200. Therefore, the rotation direction of the operating member 130 is consistent with the extension and retraction direction of the lock tongue.

[0038] In another embodiment, the lock 100 is arranged on the right side of the door panel 200, and the door panel 200 assembly is a right-opening door. The first side 112 mentioned above can be the left side of the lock 100, and the second side 113 can be the right side of the lock 100. The right side of the lock 100 is consistent with the right side of the door panel 200. At this time, OFF2 is the second locked position, that is, when the operating member 130 rotates toward the right side of the door panel 200, the lock tongue portion 120 extends from the left side to the right side of the door panel 200. When the operating member 130 rotates toward the left side of the door panel 200, the lock tongue portion 120 retracts from the right side to the left side of the door panel 200. Therefore, the rotation direction of the operating member 130 is consistent with the extension and retraction direction of the lock tongue.

[0039] In the scheme disclosed in the present application, the operating member 130 can rotate in two opposite directions in the unlocked position, so that the operating member 130 can be compatible with the extension direction of the lock tongue portion 120 on different sides. Therefore, whether it is a left-door opening scheme or a right-door opening scheme, the rotation direction of the operating member 130 is consistent with the extension direction of the lock tongue portion 120, thereby avoiding the risk of user misoperation, thereby further improving the performance of the lock 100.

[0040] The lock 100 disclosed in the present application can select a corresponding locking position in a specific application environment, while the other locking position is an empty position and is not used to drive the lock tongue portion 120 to extend. In other words, the lock 100 disclosed in the present application only uses one of the locking positions in a specific application environment. For example, Figure 4 and Figure 5 In the solution shown, since it is a left-opening solution, the locked position is the first locked position. Therefore, the operating member 130 can switch between the unlocked position and the first locked position. Due to the limitation of the retraction stroke of the bolt portion 120, the operating member 130 cannot rotate from the unlocked position to the second locked position. Figure 4 and Figure 5 In the illustrated embodiment, the operating member 130 is rotated to switch between an unlocking position and a first locking position.

[0041] Similarly, in Figure 6 and Figure 7 In the solution shown, since it is a right-opening solution, the locked position is the second locked position. Therefore, the operating member 130 can switch between the unlocked position and the second locked position. Due to the limitation of the bolt retraction stroke, the operating member 130 cannot rotate from the unlocked position to the first locked position. Figure 6 and Figure 7 In the illustrated embodiment, the operating member 130 is rotated to switch between an unlocking position and a second locking position.

[0042] In the above embodiment, the operating member 130 rotates by a first preset angle during the switching process between the unlocked position and the first locked position. At this time, the operating member 130 rotates by a first preset angle along the first rotation direction from the unlocked position to the first locked position, and the operating member 130 rotates by a first preset angle along the second direction from the first locked position to the unlocked position, that is, the operating member 130 rotates by a corresponding angle during the unlocking process as it rotates during the locking process. Similarly, the operating member 130 rotates by a second preset angle during the switching process between the unlocked position and the second locked position.

[0043] In another optional solution, the first preset angle and the second preset angle are the same. In this solution, when the operating member 130 rotates from the unlocking position to the locking position in two directions, its rotation angle is the same, thus making the structure of the lock 100 simpler and more reliable.

[0044] In the above embodiment, both the first preset angle and the second preset angle can be 90°. At this time, the unloaded rotation angle of the operating member 130 is 180°. Of course, the first preset angle and the second preset angle can also be other angles, which are not limited herein.

[0045] In another optional solution, the lock 100 may further include a drive motor 140, a transmission gear 150 and a connecting ring 160, and the drive motor 140, the transmission gear 150 and the connecting ring 160 may all be located in the lock housing 110. The transmission gear 150 may be rotatably connected to the lock housing 110 around its central axis, that is, the transmission gear 150 may be rotatable in the lock housing 110. Alternatively, the transmission gear 150 may be rotatably connected to the lock housing 110 via a rotating shaft.

[0046] The driving motor 140 can be connected to the transmission gear 150, the connecting ring 160 can be coaxially arranged with the transmission gear 150, and the operating member 130 can be fixedly connected to the connecting ring 160. At this time, the operating member 130 can be fixedly connected to the connecting ring 160 through a retaining spring 190, or can also be fixedly connected to the connecting ring 160 through bolts and other components.

[0047] During the specific operation process, the lock 100 has two opening and closing locking modes, one is a manual opening and closing locking mode, and the other is a motor driven mode. At this time, when the driving motor 140 is started, the driving motor 140 drives the connecting ring 160 to rotate through the transmission gear 150, and the connecting ring 160 drives the driving operating member 130 to rotate to drive the lock tongue portion 120 to switch between the retracted position and the extended position.

[0048] The lock 100 of the above scheme can be an electronic lock, which can start the drive motor 140 by fingerprint recognition, iris recognition, facial recognition, and password input. At this time, when the input password or identification method matches the pre-stored password or pre-stored identification method of the electronic lock, the drive motor 140 of the lock 100 is started, thereby realizing the unlocking operation.

[0049] However, since the transmission gear 150 is connected to the connecting ring 160 , when the user manually operates the operating member 130 , the driving motor 140 is linked with the operating member 130 , which may easily cause damage to the driving motor 140 , thereby shortening the service life of the driving motor 140 .

[0050] Based on this, in another optional embodiment, one of the connecting ring 160 and the transmission gear 150 is provided with a clutch groove 161, and the other is provided with a clutch protrusion 151, and the clutch protrusion 151 can slide and cooperate with the clutch groove 161 along the extension direction of the clutch groove 161.

[0051] When the clutch protrusion 151 and the clutch slide groove 161 are limitedly matched along the moving direction of the transmission gear 150, the driving motor 140 drives the connecting ring 160 to rotate through the transmission gear 150, so that the locking tongue portion 120 switches between the retracted position and the extended position. At this time, the clutch protrusion 151 can abut against the end of one end of the clutch slide groove 161, so that the clutch protrusion 151 and the clutch slide groove 161 can be relatively stationary, thereby realizing the linkage of the transmission gear 150 and the connecting ring 160.

[0052] When the clutch protrusion 151 and the clutch slide groove 161 are in sliding cooperation, the operating member 130 drives the connecting ring 160 to rotate relative to the transmission gear 150, and the connecting ring 160 can drive the locking tongue portion 120 to switch between the retracted position and the extended position. At this time, the operating member 130 is rotated manually. The clutch protrusion 151 and the clutch slide groove 161 can slide relative to each other.

[0053] In a specific embodiment, Fig.15 and Fig.16 FIG. 1 is a schematic diagram of the lock 100 applied to a left-opening door solution, wherein the clutch slide 161 has a first end and a second end. Fig.15 As shown, when the operating member 130 is in the unlocking position, the clutch protrusion 151 is located on the side close to the first end. When the lock 100 is opened and closed manually, the operating member 130 rotates from the unlocking position to the first locking position, as shown in FIG. Fig.16As shown, the clutch protrusion 151 slides from the first end of the clutch slide groove 161 to the second end of the clutch slide groove 161. Similarly, when the operating member 130 rotates from the first locking position to the unlocking position, the clutch protrusion 151 slides from the second end of the clutch slide groove 161 to the first end of the clutch slide groove 161. Fig.15 As shown, when the driving motor 140 drives the driving gear to rotate in the first rotation direction, the clutch protrusion 151 will abut against the first end. At this time, the clutch protrusion 151 will drive the connecting ring 160 to rotate in the first rotation direction together until it moves to the first locked position. When the first locked position rotates to the unlocked position, the driving motor 140 first drives the gear to idle for a certain angle in the second rotation direction, so that the clutch protrusion 151 moves to the second end, and then abuts against the second end, so that the clutch protrusion 151 will drive the connecting ring 160 to rotate in the second rotation direction together until it moves to the unlocked position.

[0054] In a specific embodiment, Fig.17 and Fig.18 FIG. 1 is a schematic diagram of the lock 100 applied to a right-opening door solution. Fig.17 As shown, when the operating member 130 is in the unlocking position, the clutch protrusion 151 is located on the side close to the second end. When the lock 100 is opened and closed manually, the operating member 130 rotates from the unlocking position to the second locking position, as shown in FIG. Fig.18 As shown, the clutch protrusion 151 slides from the second end of the clutch slide groove 161 to the first end of the clutch slide groove 161. Similarly, when the operating member 130 rotates from the second locked position to the unlocked position, the clutch protrusion 151 slides from the first end of the clutch slide groove 161 to the second end of the clutch slide groove 161. Fig.17 As shown, when the driving motor 140 drives the driving gear to rotate along the second rotation direction, the clutch protrusion 151 will abut against the second end. At this time, the clutch protrusion 151 will drive the connecting ring 160 to rotate in the second rotation direction together until it moves to the second locked position. When the second locked position rotates toward the unlocked position, the driving motor 140 first drives the gear to idle along the first rotation direction for a certain angle, so that the clutch protrusion 151 moves to the first end, and then abuts against the first end, so that the clutch protrusion 151 will drive the connecting ring 160 to rotate in the first rotation direction together until it moves to the unlocked position.

[0055] In this solution, when the lock 100 is manually operated, the operating member 130 can be separated from the drive motor 140 , thereby avoiding the risk of damage to the drive motor 140 and extending the service life of the drive motor 140 .

[0056] In the above embodiment, Fig.15 and Fig.16 In the scheme shown, when the driving motor 140 drives the operating member 130 to the unlocking position, the driving motor 140 also needs to reversely drive the transmission gear 150 so that the two ends of the clutch protrusion 151 and the clutch groove 161 slide to the first end of the clutch groove 161, so that the operating member 130 is not linked with the transmission gear 150 when it is manually rotated. At this time, the transmission gear 150 is located at the first electromechanical separation position. Fig.17 and Fig.18 In the scheme shown, when the driving motor 140 drives the operating member 130 to the unlocking position, the driving motor 140 also needs to reversely drive the transmission gear 150 so that the clutch protrusion 151 slides from one end of the clutch groove 161 to the second end of the clutch groove 161, so that the operating member 130 is not linked with the transmission gear 150 when manually rotated. At this time, the transmission gear 150 is located in the second electromechanical separation position.

[0057] In another optional embodiment, the transmission gear 150 may be provided with a receiving groove 152, and the side wall of the receiving groove 152 may be provided with a clutch protrusion 151. The outer side wall of the connecting ring 160 may be provided with a clutch slide groove 161, and at least a portion of the connecting ring 160 may be located in the receiving groove 152. This solution can further reduce the stacking height of the transmission gear 150 and the connecting ring 160, thereby facilitating a reduction in the thickness of the lock 100.

[0058] In the above embodiment, the lock 100 disclosed in the present application can specifically select the electromechanical separation position of the transmission gear 150 according to the application environment of the lock 100. At this time, the position of the electromechanical separation gear can be manually adjusted during the assembly of the lock 100. However, the manual adjustment of the position of the electromechanical separation gear has poor accuracy, and the drive motor 140 is also prone to lose the electromechanical separation position during the rotation process, which can easily lead to poor reliability of the lock 100.

[0059] Based on this, in another optional embodiment, a first detection member 171 and a second detection member 172 may be provided in the lock housing 110; when the transmission gear 150 triggers the first detection member 171, the transmission gear 150 is in the first electromechanical separation position, and the clutch protrusion 151 and the clutch slide 161 can slide relative to each other in the switching direction between the unlocking position and the first locking position. In this solution, the first electromechanical separation position is detected and positioned by the first detection member 171, thereby improving the setting accuracy of the first electromechanical separation position, and also making it difficult for the drive motor 140 to lose the electromechanical separation position during the rotation process, thereby improving the reliability of the lock 100.

[0060] Similarly, when the transmission gear 150 triggers the second detection member 172, the transmission gear 150 is in the second electromechanical separation position, and the clutch protrusion 151 and the clutch slide groove 161 can slide relative to each other in the switching direction between the unlocking position and the second locking position. This solution has the same effect as the above solution, and will not be described in detail herein.

[0061] The present application can locate the first electromechanical separation position and the second electromechanical separation position through the first detection member 171 and the second detection member 172, thereby avoiding the risk of the electromechanical separation position being lost when the lock 100 is in use.

[0062] In a specific application environment of the lock 100 of the present application, one of the first detection member 171 and the second detection member 172 is in operation, and the other is in a non-operating state. For example, in a left-opening door solution, the first detection member 171 is in operation, and the second detection member 172 is in a non-operating state. In a right-opening door solution, the second detection member 172 is in operation, and the first detection member 171 is in a non-operating state.

[0063] In another optional embodiment, the transmission gear 150 may be provided with a first protrusion 153, the first detection member 171 may be a first optical coupler, and the second detection member 172 may be a second optical coupler. When at least a portion of the first protrusion 153 is located in the groove of the first optical coupler, the first optical coupler is triggered; when at least a portion of the first protrusion 153 is located in the groove of the second optical coupler, the second optical coupler is triggered.

[0064] Specifically, the first optical coupler and the second optical coupler may each include a bracket, a transmitter and a receiver. The bracket is provided with a groove, and the groove has a first side wall 112 and a second side wall 113 that are arranged opposite to each other. The transmitter may be arranged on the first side wall 112, and the receiver may be arranged on the second side wall 113. When the first protrusion 153 is located outside the groove, the light signal emitted by the transmitter may be received by the receiver. When part of the first protrusion 153 moves into the groove, the light signal emitted by the transmitter is blocked by the first protrusion 153, so the receiver cannot receive the light signal, thereby causing the first optical coupler or the second optical coupler to generate a signal, so the relative position of the transmission gear 150 can be located by the signal generated by the first optical coupler or the second optical coupler.

[0065] In this solution, the position of the transmission gear 150 is positioned by an optical coupler. The optical coupler has a simple structure, so the structure of the lock 100 is simple, thereby reducing the cost of the lock 100.

[0066] Of course, the first detection member 171 and the second detection member 172 are not limited to optical couplers, but can also be contact switches. When the first protrusion 153 contacts the first contact switch, it is determined that the transmission gear 150 is in the first electromechanical separation position. When the first protrusion 153 contacts the second contact switch, it is determined that the transmission gear 150 is in the second electromechanical separation position.

[0067] In the above embodiment, when the lock 100 is electrically driven, the driving motor 140 can record the unlocked or locked state of the lock 100 according to its rotation direction. However, when the lock 100 is manually operated, the unlocked or locked state cannot be determined.

[0068] Based on this, in another optional embodiment, a third detection member 173 may be provided in the lock housing 110, and the third detection member 173 may be used to detect the rotation position of the connecting ring 160, so as to detect the open and closed state of the lock 100. At this time, since the operating member 130 is linked with the connecting ring 160, the open and closed state of the lock 100 can be determined by detecting the position of the connecting ring 160. For example, the third detection member 173 may be an angle detection sensor, and when the angle detected by the angle detection sensor is 0°, the operating member 130 is located in the unlocking position, so the lock 100 is in the unlocking state. When the angle detected by the angle sensor is 90°, the operating member 130 is located in the first locking position or the second locking position, so the lock 100 is in the locking position.

[0069] Further, the connecting ring 160 is provided with a second protrusion 162, a third protrusion 163 and a fourth protrusion 164, and the second protrusion 162, the third protrusion 163 and the fourth protrusion 164 can be arranged at intervals along the circumference of the connecting ring 160. The third detection member 173 can include a third optical coupler 1731 and a fourth optical coupler 1732, and the third optical coupler 1731 and the fourth optical coupler 1732 are arranged at intervals; when one of the second protrusion 162, the third protrusion 163 and the fourth protrusion 164 is located in the groove of the third optical coupler 1731, the third optical coupler 1731 is triggered; when one of the second protrusion 162, the third protrusion 163 and the fourth protrusion 164 is located in the groove of the fourth optical coupler 1732, the fourth optical coupler 1732 is triggered.

[0070] In this solution, through the different triggering states of the third optical coupler 1731 and the fourth optical coupler 1732 , the position of the connecting ring 160 can be detected more accurately, so that the open and closed lock states of the lock 100 can be recorded more accurately.

[0071] In a specific embodiment, Fig.15In the illustrated solution, when the lock 100 is in the unlocked state, at least a portion of the second protrusion 162 is located in the groove of the third optical coupler 1731, and at least a portion of the fourth protrusion 164 is located in the groove of the fourth optical coupler 1732. Therefore, when both the third optical coupler 1731 and the fourth optical coupler 1732 are triggered to output signals, the lock 100 is in the unlocked state. Fig.16 As shown, when the lock 100 is in the locked state, at least a portion of the third protrusion 163 is located in the groove of the fourth optical coupler 1732, and the third optical coupler 1731 is not triggered. Therefore, when only the fourth optical coupler 1732 is triggered to output a signal, the lock 100 is in the locked state of the left-open door.

[0072] In another specific embodiment, in Fig.17 In the illustrated solution, when the lock 100 is in the unlocked state, at least a portion of the second protrusion 162 is located in the groove of the third optical coupler 1731, and at least a portion of the fourth protrusion 164 is located in the groove of the fourth optical coupler 1732. Therefore, when both the third optical coupler 1731 and the fourth optical coupler 1732 are triggered to output signals, the lock 100 is in the unlocked state. Fig.18 As shown, when the lock 100 is in the locked state, at least a portion of the third protrusion 163 is located in the groove of the third optical coupler 1731, and the fourth optical coupler 1732 is not triggered. Therefore, when only the third optical coupler 1731 is triggered to output a signal, the lock 100 is in the locked state of the right-open door.

[0073] Of course, the present application can also detect the open / closed lock state of the lock 100 in other ways, which are not limited to the methods described above.

[0074] In the embodiment disclosed in the present application, the operating member 130 may include a screwing portion 131 and a connecting rod 132, one end of the connecting rod 132 may be connected to the screwing portion 131, and the other end of the connecting rod 132 may extend into the lock housing 110 through the mounting hole 111 and be connected to the lock tongue portion 120. The screwing portion 131 here provides a screwing position for the user, and the connecting rod 132 is used to connect the screwing portion 131 with the lock tongue portion 120. Optionally, the screwing portion 131 may be a knob, which is located on the outside of the lock housing 110, and the user may operate the lock tongue portion 120 through the knob. Alternatively, the screwing portion 131 may also be a lock core, which needs to be matched with a key, and the user inserts the key into the lock hole of the lock core before being able to screw the lock core. Of course, the operating member 130 may also be a handle. The specific structure of the operating member 130 is not limited herein.

[0075] In the above embodiment, in order to ensure that the third detection component 173 can record the open and closed lock status of the lock 100 in real time, the lock 100 needs to be powered on at all times, that is, the lock 100 needs to be powered on, which causes the lock 100 to consume more energy, which is not conducive to the long battery life of the lock 100.

[0076] Based on this, in another optional embodiment, a fourth detection member 174 may be further provided in the lock housing 110, and the fourth detection member 174 may be used to detect whether the connecting rod 132 rotates, and send a power-on signal to the lock 100 when the connecting rod 132 rotates. In this solution, the lock 100 is powered on by detecting the rotation state of the connecting rod 132 to wake up the lock 100, thereby avoiding the lock 100 being powered on for a long time, so that the lock 100 can reduce energy consumption, which is more conducive to the long battery life of the lock 100.

[0077] Specifically, when the lock 100 is kept in an unlocked state or a locked state for a long time, the lock 100 can be automatically powered off, so that the lock 100 is in a dormant state. Here, when the lock 100 is kept in a state for a certain period of time, the lock 100 can be powered off and put into dormancy. When the fourth detection member 174 detects that the connecting rod 132 rotates, the lock 100 is powered on, thereby waking up the lock 100. When the lock 100 is kept for a certain period of time again without performing an unlocking or locking operation, the lock 100 is powered off and put into dormancy. Repeating the operation in sequence can reduce the energy consumption of the lock 100.

[0078] In the above embodiment, the rotation angle of the connecting rod 132 can be detected. In this case, the fourth detecting member 174 can be an angle detection sensor.

[0079] In another optional scheme, the fourth detection member 174 can be a travel switch, which can include a switch body 1741 and a contact spring 1742. The switch body 1741 can be arranged in the lock housing 110, and the contact spring 1742 can be connected to the switch body 1741. The elastic change of the contact spring 1742 can trigger the switch body 1741 to send a power-on signal.

[0080] The connecting rod 132 may include a rod body 1321 and an arc-shaped protrusion 1322 . The arc-shaped protrusion 1322 may be disposed on a portion of the outer surface of the rod body 1321 . The contact spring 1742 abuts against the connecting rod 132 .

[0081] During the rotation of the connecting rod 132 , the arc-shaped protrusion 1322 and the rod body 1321 can switch to abut against the contact spring piece 1742 , so that the contact spring piece 1742 undergoes elastic changes.

[0082] Since the arc-shaped protrusion 1322 protrudes from the outer surface of the rod body 1321, the elastic force of the arc-shaped protrusion 1322 on the contact spring 1742 is greater than the elastic force of the rod body 1321 on the contact spring 1742. Therefore, the force of the contact spring 1742 on the switch body 1741 is different, so that the switch body 1741 can be triggered during the rotation of the connecting rod 132.

[0083] In this solution, the rotation state of the connecting rod 132 can be detected more accurately through the travel switch, so as to more accurately control the power-on of the lock 100, further improving the reliability of the lock 100.

[0084] Specifically, Fig.19 The middle operating member 130 is in the unlocking position, Fig. 20 The operating member 130 is in the first locking position, Fig.21 The operating member 130 is in the second locking position. Fig.19 In the unlocked position shown in FIG. 1 , the arc-shaped protrusion 1322 abuts against the contact spring 1742. At this time, the contact spring 1742 is in a compressed state. Fig. 20 When the operating member 130 is in the first locked position, the rod body 1321 abuts against the contact spring 1742. Since the surface of the arc-shaped protrusion 1322 is higher than the surface of the rod body 1321, the contact spring 1742 recovers its deformation, so that the contact spring 1742 is in a relaxed state. Therefore, when the operating member 130 is rotated from the unlocked position to the first locked position, the contact spring 1742 switches from a compressed state to a relaxed state. Conversely, when the operating member 130 is rotated from the first locked position to the unlocked position, the contact spring 1742 switches from a relaxed state to a compressed state.

[0085] Similarly, when the operating member 130 is rotated to Fig.21 When the operating member 130 is in the second locked position, the contact spring 1742 is switched from the compressed state to the relaxed state. Conversely, when the operating member 130 is rotated from the second locked position to the unlocked position, the contact spring 1742 is switched from the relaxed state to the compressed state.

[0086] In the above embodiment, the contact spring piece 1742 may be a straight strip structure. Alternatively, in another optional embodiment, the contact spring piece 1742 may include a first elastic arm section 1742a, an arc section 1742b, and a second elastic arm section 1742c. The first elastic arm section 1742a may be connected to the second elastic arm section 1742c through the arc section 1742b, and the arc section 1742b may abut against the connecting rod 132. In this solution, the contact spring piece 1742 is provided with an arc section 1742b, so the arc section 1742b cooperates more smoothly with the connecting rod 132 during the rotation process of the connecting rod 132, so it is not easy to cause the problem of collision with the connecting rod 132 and the contact spring piece 1742, thereby improving the safety of the lock 100. In addition, the first elastic arm section 1742a, the arc section 1742b, and the second elastic arm section 1742c form a bent structure, which also improves the rigidity and strength of the contact spring piece 1742.

[0087] In another optional scheme, the number of the arc-shaped protrusions 1322 can be two, namely the first arc-shaped protrusion and the second arc-shaped protrusion, and the first arc-shaped protrusion and the second arc-shaped protrusion are located on opposite sides of the rod body 1321, that is, the first arc-shaped protrusion and the second arc-shaped protrusion are distributed at intervals along the circumference of the rod body 1321.

[0088] During the rotation of the connecting rod 132 , at least one of the first arc-shaped protrusion and the second arc-shaped protrusion can switch with the rod body 1321 to abut against the contact spring piece 1742 , so that the contact spring piece 1742 undergoes elastic changes.

[0089] The lock 100 disclosed in the present application further includes a circuit board 180 . The driving motor 140 , the first detection member 171 , the second detection member 172 , the third detection member 173 and the fourth detection member 174 may all be disposed on the circuit board 180 and electrically connected to the circuit board 180 .

[0090] In the related art, the lock 100 usually includes a first device body and a second device body. The first device body is installed on the first surface of the door panel 200. At this time, the first device body is used to open and close the door from the inside of the room. The second device body is installed on the second surface of the door panel 200. At this time, the second device body is used to open and close the door from the outside of the room.

[0091] Based on this, in one scheme, the lock shell 110 may include a first shell 1101 and a second shell 1102, and the first shell 1101 and the second shell 1102 are located on opposite sides of the lock tongue. The first shell 1101 and the second shell 1102 may both be provided with mounting holes 111, and the number of operating members 130 may be at least two, namely the first operating member 131 and the second operating member 132, and a portion of the first operating member 131 may be installed in the mounting hole 111 of the first shell 1101 and connected to the lock tongue portion 120; a portion of the second operating member 132 may be installed in the mounting hole 111 of the second shell 1102 and connected to the lock tongue.

[0092] At this time, the first shell 1101 here can be the corresponding shell of the first device body, and the second shell 1102 can be the corresponding shell of the second device body. Therefore, the first shell 1101 is installed on the first surface of the door panel 200, and the second shell 1102 is installed on the second surface of the door panel 200. At this time, the corresponding first operating member 131 on the first shell 1101 and the corresponding operating member 130 on the second shell 1102 both have two locking positions.

[0093] In a specific embodiment, Fig. 22 As shown, the first operating member 131 on the first housing 1101 may be a knob, and the second operating member 132 on the second housing 1102 may be a lock core. In this case, the user can open and close the door from both the inside and the outside of the door.

[0094] In the above embodiment, the lock tongue portion 120 can be set in the door panel 200. Of course, the lock tongue can also be set on the first shell 1101 or the second shell 1102. In this case, corresponding openings can be set on the door panel 200, the first shell 1101 or the second shell 1102 for the lock tongue portion 120 to extend or retract.

[0095] Based on the lock 100 disclosed in the embodiment of the present application, the embodiment of the present application further discloses a door assembly, and the disclosed door assembly includes the lock 100 described in any of the above embodiments.

[0096] The door assembly disclosed in the present application also includes a door panel 200 and a door frame. Fig. 22As shown, the door panel 200 is provided with a receiving space 230 and a first opening 210 and a second opening 220 connected to the receiving space 230. The lock housing 110 is connected to the door panel 200, and the bolt portion 120 is movably located in the receiving space 230. The operating member 130 can be connected to the bolt portion 120 through the first opening 210. A portion of the bolt portion 120 can extend out of the door panel 200 or retract into the receiving space 230 through the second opening 220. When the bolt portion 120 extends to the extended position, the bolt portion 120 can extend into the slot on the door frame, so that the door panel 200 is locked with the door frame. When the bolt portion 120 retracts to the retracted position, the bolt portion 120 can be pushed out of the slot on the door panel 200, so that the door panel 200 is unlocked from the door frame.
