AI Technical Summary
Existing locks require a cumbersome configuration process after installation to determine the unlocking and locking directions, especially when the lock is installed in the opposite direction to the default direction, requiring installers to manually test, observe, and configure them.
By using an elastic element in the lock to apply force to the first bolt, causing it to extend in a specific direction, and using a motor to drive the moving parts to retract or extend the bolt, the relative relationship between the default unlocking direction and the actual unlocking direction is automatically determined by detecting the magnitude of the current when the motor rotates.
It enables automatic lock configuration, simplifies the installation process, and can automatically set the actual unlocking and locking directions of the lock within 1 to 2 seconds, making it suitable for different installation scenarios.

Abstract
Description
Technical Field
[0001] This application relates to the field of lock technology, and in particular to a control method, a lock structure, and a lock. Background Technology
[0002] With the development of technology, various types of locks have emerged and are installed on doors, windows, or other items that need to be opened and closed. For example, as a type of lock, the most common fully automatic door lock on the market today uses a backpack motor and a mechanical lock body. Specifically, the backpack motor rotates, driving the lock tongue of the lock body to extend / retract, thus opening and closing the lock. Because users' doors open in different directions, the door lock may be installed on the left or right side of the door, so in these two cases, the direction of rotation of the backpack motor driving the lock body to open and close the lock is opposite.
[0003] Since locks can only be set to one default unlocking direction at the factory, configuration is required after installation at the user's end, depending on the specific situation. Currently, the common practice is to power on the lock after installation to test and observe whether the default unlocking and locking directions are normal. If not, specific commands are entered on the lock's control panel to access the motor function settings. Then, the motor rotation direction is selected according to the prompts to set the actual unlocking and locking directions. After setting, the process is verified to ensure it is working correctly. This entire process requires installers to test, observe, configure, and verify, making the configuration process cumbersome. Summary of the Invention
[0004] This application provides a control method, a lock / switch structure, and a lock, which can conveniently configure the actual unlocking direction and the actual locking direction of the lock.
[0005] In a first aspect, embodiments of this application provide a control method for a switch lock structure, the switch lock structure comprising:
[0006] First locking tongue;
[0007] An elastic element is used to apply a force along a first direction to the first latch, so that the first latch extends along the first direction;
[0008] The second locking tongue is spaced apart from the first locking tongue;
[0009] A switch assembly includes a motor and a moving component connected by a drive. When the motor drives the moving component to rotate in the actual unlocking direction, the moving component causes the first latch and the second latch to retract together in a second direction, and also enables the moving component to cause the first latch to retract alone in the second direction, the second direction being opposite to the first direction. When the motor drives the moving component to rotate in the actual locking direction, the moving component causes the second latch to extend alone in the first direction, the actual unlocking direction being opposite to the actual locking direction.
[0010] A detection element is used to detect the magnitude of the current when the motor drives the moving part to rotate.
[0011] The control method includes:
[0012] The motor drives the moving part to rotate from the initial position toward the default unlocking direction, and stops rotating when the current value detected by the detection device is greater than the stall threshold.
[0013] The motor drives the moving part to rotate to the initial position in the default locking direction, where the default locking direction is opposite to the default unlocking direction.
[0014] The motor drives the moving part to rotate from the initial position toward the default locking direction, and stops rotating when the current value detected by the detection element is greater than the stall threshold.
[0015] The motor is used to drive the moving part to rotate in the default unlocking direction to the initial position;
[0016] The motor drives the moving part to rotate from the initial position toward the default locking direction, and stops rotating when the current value d detected by the detection element is greater than the stall threshold. The duration t during this process when d is greater than the preset threshold c is obtained.
[0017] If t is greater than the first preset time T1, the default unlocking direction is set to the actual locking direction, and the default locking direction is set to the actual unlocking direction; otherwise, the default unlocking direction is set to the actual unlocking direction, and the default locking direction is set to the actual locking direction.
[0018] In some embodiments, the preset threshold c and the first preset time T1 are obtained in the following manner:
[0019] The motor is obtained when it drives the moving part to rotate, and neither the first latch nor the second latch is in contact with the moving part. The motor is also obtained when it drives the moving part to rotate, and the moving part causes the first latch to retract along the second direction alone. The motor is also obtained when it drives the moving part to rotate, and the second current value b and the time T0 required are obtained. Half of T0 is set as the first preset time T1.
[0020] Calculate the preset threshold c = a + (ba) / 2.
[0021] In some embodiments, driving the moving part to rotate toward the default locking direction to the initial position using the motor includes:
[0022] The motor is used to drive the moving part to rotate in the default locking direction for a second preset time T2, at which time the moving part is located in the initial position;
[0023] Alternatively, the switch lock structure may further include a sensor switch, using the motor to drive the moving part to rotate in the default locking direction so that the moving part triggers the sensor switch, at which point the moving part is in the initial position.
[0024] In some embodiments, driving the moving part to rotate toward the default unlocking direction to the initial position using the motor includes:
[0025] The motor drives the moving part to rotate in the default unlocking direction for a third preset time T3, at which time the moving part is located in the initial position;
[0026] Alternatively, the switch lock structure may further include a sensor switch, using the motor to drive the moving part to rotate in the default unlocking direction until the moving part triggers the sensor switch, at which point the moving part is in the initial position.
[0027] Secondly, embodiments of this application provide a switch lock structure, which uses the control method described in the first aspect.
[0028] In some embodiments, the moving part includes a rotating part and a actuating part connected together. The rotating part is drivenly connected to the motor, and the actuating part is used to rotate together with the rotating part about the axis of the rotating part to actuate the first latch and the second latch.
[0029] In some embodiments, the rotating part is located on the side of the second latch opposite to the first latch;
[0030] The first latch includes a first part and a second part connected to each other. The first part extends along the first direction, and one end of the first part away from the second part extends along the first direction. The extension direction of the second part is set at an angle to the first direction. One end of the second part away from the first part extends along a direction close to the second latch. The actuating part is used to actuate the second part.
[0031] And / or, the second latch includes a third part and a fourth part connected together, the third part extending along the first direction, and the end of the third part away from the fourth part being used to extend along the first direction, the extension direction of the fourth part being set at an angle to the first direction, the end of the fourth part away from the first part extending along a direction close to the first latch, and the actuating part being used to actuate the fourth part.
[0032] In some embodiments, the switch lock structure further includes a support, the support and the first latch are arranged sequentially and at intervals along the first direction, the elastic element is located between the support and the first latch, and the two ends of the elastic element abut against the support and the first latch respectively.
[0033] In some embodiments, the switch lock structure further includes a slider connected to the first latch, the slider being slidably connected to the support, and the sliding direction of the slider relative to the support being parallel to the first direction.
[0034] Thirdly, embodiments of this application provide a lock, which includes the switch lock structure as described in the second aspect.
[0035] The advantages of the switch lock structure provided in this application embodiment are as follows: Since the elastic element applies a force along the first direction to the first latch, causing the first latch to extend along the first direction, and the second latch is spaced apart from the first latch; and when the motor drives the moving part to rotate in the actual unlocking direction, the moving part causes the first and second latches to retract together along the second direction, or the moving part can cause the first latch to retract alone along the second direction. When the motor drives the moving part to move in the actual locking direction, the moving part causes the second latch to extend alone along the first direction. Therefore, by driving the moving part to rotate in different directions and detecting the current magnitude corresponding to the motor driving the moving part to rotate, it is possible to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction. This allows for convenient configuration of the actual unlocking and actual locking directions of the lock, making it suitable for different installation scenarios.
[0036] The advantages of the control method and lock of the switch-lock structure provided in this application compared with the prior art can be found in the description of the advantages of the switch-lock structure provided in this application compared with the prior art, which will not be repeated here.

[0072] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0073] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0074] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0075] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.
[0076] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.
[0077] With the development of technology, various types of locks have emerged and are installed on doors, windows, or other items that need to be opened and closed. For example, as a type of lock, the most common fully automatic door lock on the market today uses a backpack motor and a mechanical lock body. Specifically, the backpack motor rotates, driving the lock tongue of the lock body to extend / retract, thus opening and closing the lock. Because users' doors open in different directions, the door lock may be installed on the left or right side of the door, so in these two cases, the direction of rotation of the backpack motor driving the lock body to open and close the lock is opposite.
[0078] Since locks can only be set to one default unlocking direction at the factory, configuration is required after installation at the user's end, depending on the specific situation. Currently, the common practice is to power on the lock after installation to test and observe whether the default unlocking and locking directions are normal. If not, specific commands are entered on the lock's control panel to access the motor function settings. Then, the motor rotation direction is selected according to the prompts to set the actual unlocking and locking directions. After setting, the process is verified to ensure it is working correctly. This entire process requires installers to test, observe, configure, and verify, making the configuration process cumbersome.
[0079] In view of this, this application provides a control method, a lock / switch structure, and a lock. Since the elastic element applies a force along a first direction to the first latch, causing it to extend along that direction, and the second latch is spaced apart from the first latch; and the motor drives the moving part to rotate in the actual unlocking direction, causing the moving part to retract both the first and second latches along the second direction, or enabling the moving part to retract the first latch alone along the second direction; and the motor drives the moving part to move in the actual locking direction, causing the moving part to extend the second latch alone along the first direction, the moving part can be driven to rotate in different directions by the motor, and the current magnitude corresponding to the motor driving the moving part can be detected by the detection element to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction. This allows for convenient configuration of the actual unlocking and locking directions of the lock, making it suitable for different installation scenarios.
[0080] Please refer to Figure 1 (a) and Figure 1 In (b) of this application, the first aspect is that the present application provides a control method for a switch lock structure. The switch lock structure is used in a lock. The lock includes a control unit (such as a main control chip) and a switch lock structure. The switch lock structure includes a first latch 10, a second latch 30, a switch assembly, and a detection element (not shown in the figure).
[0081] The elastic element 20 is used to apply a force along a first direction to the first latch 10 so that the first latch 10 extends along the first direction.
[0082] The elastic element 20 can be a spring, elastic rubber, or elastic silicone, etc. The first direction can be... Figure 1 The direction indicated by the middle arrow H.
[0083] The second locking tongue 30 is spaced apart from the first locking tongue 10.
[0084] The first locking tongue 10 can be a slanted tongue, and the second locking tongue 30 can be a square tongue.
[0085] The switch assembly includes a motor (not shown in the figure) and a moving component connected by a drive. When the motor drives the moving component to rotate in the actual unlocking direction, the moving component causes the first latch 10 and the second latch 30 to retract together along a second direction. It also allows the moving component to cause the first latch 10 to retract independently along the second direction. The second direction is opposite to the first direction. The second direction can be... Figure 1 In the direction indicated by the middle arrow I, when the motor drives the moving part to rotate in the actual locking direction, the moving part causes the second locking tongue 30 to extend out alone in the first direction, and the actual unlocking direction is opposite to the actual locking direction.
[0086] The rotation direction of the motor and the rotation direction of the rotating component can be the same or opposite. In the illustrated embodiment, the rotation direction of the motor and the rotation direction of the rotating component are the same. The movement of the first locking tongue 10 and the movement of the second locking tongue 30 are independent of each other.
[0087] The detection device is used to detect the magnitude of the current when the motor drives the moving parts to rotate.
[0088] The detection device may include the ADC (Analog to Digital Converter) of the control unit. Both the control unit and the detection device can be electrically connected to the motor. The control unit can control the motor to rotate in different directions. The control unit may also include timers, etc.
[0089] After the lock with the switch-lock structure provided in the above embodiments is installed, the initial rotation direction of the moving part includes the default unlocking direction and the default locking direction which is opposite to the default unlocking direction. However, due to the different installation directions of the lock, the initial state of the switch-lock structure is uncertain. That is, the default unlocking direction may be the same as or opposite to the actual unlocking direction required. The second latch 30 may extend or retract, while the first latch 10 will be in the extended state in both cases due to the force of the elastic element 20. Therefore, it is necessary to confirm the relationship between the two and configure them accordingly.
[0090] Traditional methods require installers to test, observe, configure, and verify the lock, making the entire process cumbersome. However, the switch lock structure provided in this application can detect the magnitude of the current when the motor drives the moving parts to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction, thus making it easier to configure the actual unlocking and locking directions of the lock.
[0091] Please refer to this as well. Figures 1 to 22 The control method for the switch lock structure provided in this application includes:
[0092] First, the moving part is driven by a motor to rotate from its initial position toward the default unlocking direction, and the rotation stops when the current value detected by the detection device is greater than the stall threshold.
[0093] exist Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 14 , Figure 16 , Figure 18 , Figure 20 as well as Figure 22 In the diagram, the horizontal axis can be in seconds, and the vertical axis can be in amperes.
[0094] Specifically, the stall threshold can be the current value corresponding to the stall condition of the moving part, where the moving part cannot continue to rotate when stalled. Figure 2 As shown, the moving part is abutting against the second locking tongue 30 at this time.
[0095] It should be noted that although the trends of the current value and time correspondence in the various graphs are roughly the same, the motor current is larger when both the oblique tongue and the square tongue are driven at the same time than when they are driven separately.
[0096] Secondly, the moving parts are driven by a motor to rotate to the initial position in the default locking direction, which is opposite to the default unlocking direction.
[0097] Next, the moving part is driven by a motor to rotate from the initial position toward the default locking direction, and stops rotating when the current value detected by the detection device is greater than the stall threshold.
[0098] Then, the moving parts are driven by the motor to rotate to the initial position in the default unlocking direction.
[0099] Next, the moving part is driven by a motor to rotate from the initial position toward the default locking direction, and stops rotating when the current value d detected by the detection element is greater than the stall threshold. The duration t during this process when d is greater than the preset threshold c is obtained. t can be obtained by directly detecting the timer of the control unit or by setting the timer separately.
[0100] If t is greater than the first preset time T1, the default unlocking direction is set to the actual locking direction, and the default locking direction is set to the actual unlocking direction; otherwise, the default unlocking direction is set to the actual unlocking direction, and the default locking direction is set to the actual locking direction.
[0101] Please refer to the following for details. Figures 1 to 11 After installing the lock with the switch-lock structure provided in the above embodiments, if the default unlocking direction is the same as the actual unlocking direction required, such as in Figures 8 to 10 In the stage shown, the moving part is driven by the motor to rotate from the initial position to the default locking direction, and stops rotating when the current value d detected by the detector is greater than the stall threshold. During the process of obtaining the duration t of d being greater than the preset threshold c, the motor will idle to the end until the moving part is pressed against the second locking tongue 30, and d is greater than the stall threshold. The corresponding operating current value d of the motor includes the current value of the motor when it is idling, the current value of the motor when the moving part is pressed against the second locking tongue 30, and the stall threshold when the moving part stalls in the last stage. Stalling begins when the moving part is pressed against the second locking tongue 30. The current d will increase instantaneously when stalling, so the time when d is greater than c is very short, and t is less than T1.
[0102] Please refer to the following for details. Figures 12 to 22 When a lock having the switch-lock structure provided in the above embodiments is installed, if the default unlocking direction is opposite to the actual unlocking direction required, such as in Figures 19 to 21 In the stage shown, the moving part is driven by the motor to rotate from the initial position to the default locking direction, and stops rotating when the current value d detected by the detector is greater than the stall threshold. During the process of obtaining the duration t during which d is greater than the preset threshold c, the motor will idle for a certain distance before the moving part abuts against the first locking tongue 10, and then against the second locking tongue 30, until stalling. The corresponding operating current value d of the motor includes the current value when the motor is idling, the current value of the motor when the moving part abuts against the first locking tongue 10, the current value of the motor when the moving part abuts against the second locking tongue 30, and the stall threshold when the moving part stalls in the last stage. The current values of the motor when the moving part abuts against the first locking tongue 10, the current values of the motor when the moving part abuts against the second locking tongue 30, and the current values of the motor when stalling are all greater than c, and t is greater than T1.
[0103] Therefore, it can be determined that if t is greater than T1, the default unlocking direction will be set to the actual locking direction, and the default locking direction will be set to the actual unlocking direction. Otherwise, the default unlocking direction will be set to the actual unlocking direction, and the default locking direction will be set to the actual locking direction. During this process, the lock's control unit can automatically determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction, and automatically set the default unlocking direction to the actual unlocking direction or the actual locking direction. No manual trial, observation, configuration, or verification is required, and the entire process is simple to operate.
[0104] As can be seen from the above, the control method of the lock and switch structure provided in this application, since the elastic element 20 is used to apply a force along the first direction to the first latch 10 so that the first latch 10 extends along the first direction, and the second latch 30 is spaced apart from the first latch 10; and when the motor is used to drive the moving part to rotate in the actual unlocking direction, the moving part drives the first latch 10 and the second latch 30 to retract together in the second direction, or the moving part can drive the first latch 10 to retract alone in the second direction. When the motor is used to drive the moving part to move in the actual locking direction, the moving part drives the second latch 30 to extend alone in the first direction, so the motor can drive the moving part to rotate in different directions, and the detection element can detect the current magnitude of the motor when driving the moving part to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction, so that the actual unlocking direction and the actual locking direction of the lock can be configured more conveniently, and it is suitable for different installation scenarios.
[0105] Please refer to Figure 11 and Figure 22 In this embodiment, the preset threshold c and the first preset time T1 are obtained in the following way:
[0106] First, obtain the first current value a of the motor when the motor drives the moving part to rotate and neither the first locking tongue 10 nor the second locking tongue 30 is in contact with the moving part, and the second current value b of the motor when the motor drives the moving part to rotate, so that the moving part drives the first locking tongue 10 to retract alone in the second direction, and the time T0 required. Set 1 / 2 of T0 as the first preset time T1.
[0107] Next, calculate the preset threshold c = a + (ba) / 2.
[0108] By adopting the above scheme, the preset threshold c and the first preset time T1 can be obtained relatively easily.
[0109] It should be noted that the first current value 'a' can be the current value corresponding to the motor idling, and the second current value 'b' can be the current value corresponding to the motor driving the moving parts to rotate, thereby driving the first latch 10 (slanted latch). When the motor rotates to the bottom and stalls, the corresponding current increases sharply before stopping. Specifically, the current when the motor is idling is 'a', and the current increases significantly to 'b' when driving the slanted latch to retract. The currents 'a', 'b', and the first preset time T1 are affected by different motor models and lock bodies, and can be obtained through pre-testing of similar switch and lock structures before leaving the factory.
[0110] The process of using a motor to drive a moving part to rotate to its initial position in the default locking direction includes:
[0111] The moving part is driven by a motor to rotate in the default locking direction for a second preset time T2, at which time the moving part is in the initial position.
[0112] For example, T2 can be obtained by pre-testing similar switch and lock structures before the equipment leaves the factory.
[0113] Alternatively, the switch lock structure may also include a sensor switch, using a motor to drive a moving part to rotate in the default locking direction until the moving part triggers the sensor switch, at which point the moving part is in the initial position.
[0114] By adopting the above scheme, it is relatively easy to use a motor to drive the moving parts to rotate to the initial position in the default locking direction.
[0115] The process of using a motor to drive a moving part to rotate to its initial position in the default unlocking direction includes:
[0116] The moving part is driven by a motor to rotate in the default unlocking direction for a third preset time T3, at which point the moving part is in the initial position.
[0117] For example, T3 can be obtained by pre-testing similar switch and lock structures before the equipment leaves the factory.
[0118] Alternatively, the switch lock structure may also include a sensor switch, using a motor to drive a moving part to rotate in the default unlocking direction until the moving part triggers the sensor switch, at which point the moving part is in its initial position.
[0119] By adopting the above solution, it is relatively easy to use a motor to drive the moving parts to rotate to the initial position in the default unlocking direction.
[0120] Please refer to Figures 1 to 22 Secondly, embodiments of this application provide a switch lock structure that uses the control method as described in the first aspect.
[0121] The lock / switching structure provided in this application allows for convenient configuration of the lock's actual unlocking and locking directions. The elastic element 20 applies a force along a first direction to the first latch 10, causing it to extend along that direction. The second latch 30 is spaced apart from the first latch 10. When the motor drives the moving part to rotate in the actual unlocking direction, it causes the first latch 10 and the second latch 30 to retract together along the second direction, or it can cause the first latch 10 to retract independently along the second direction. When the motor drives the moving part to move in the actual locking direction, it causes the second latch 30 to extend independently along the first direction. Therefore, by driving the moving part to rotate in different directions and detecting the current magnitude of the motor driving the moving part, it is possible to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction. This makes it suitable for various installation scenarios.
[0122] In this embodiment, the moving part includes a rotating part 40 and a toggle part 50 connected to each other. The rotating part 40 is connected to the motor drive, and the toggle part 50 is used to rotate together with the rotating part 40 around the axis of the rotating part 40 to actuate the first locking tongue 10 and the second locking tongue 30.
[0123] By adopting the above scheme, it is easy to use a motor to drive the moving parts to rotate in different directions, so that the moving parts can drive the first locking tongue 10 and the second locking tongue 30 to retract or extend.
[0124] It should be noted that the rotating part 40 can be configured as a gear, pulley or disc, etc., and the motor is used to drive the actuating part 50 and the rotating part 40 to rotate together around the axis of the rotating part 40.
[0125] Optionally, the rotating part 40 is located on the side of the second latch 30 opposite to the first latch 10.
[0126] The first latch 10 includes a first part 11 and a second part 12 connected to each other. The first part 11 extends along a first direction, and the end of the first part 11 away from the second part 12 extends along the first direction. The extension direction of the second part 12 is set at an angle to the first direction. The end of the second part 12 away from the first part 11 extends along a direction close to the second latch 30. The actuating part 50 is used to actuate the second part 12.
[0127] And / or, the second latch 30 includes a third part 31 and a fourth part 32 connected together. The third part 31 extends along a first direction, and the end of the third part 31 away from the fourth part 32 is used to extend along the first direction. The extension direction of the fourth part 32 is set at an angle to the first direction. The end of the fourth part 32 away from the first part 11 extends along a direction close to the first latch 10. The actuating part 50 is used to actuate the fourth part 32.
[0128] This configuration simplifies the structure of the first latch 10 and / or the second latch 30, making it easier for the actuating part 50 to move the first latch 10 and the second latch 30.
[0129] In this embodiment, the switch lock structure further includes a support 60, the support 60 and the first latch 10 are arranged sequentially and at intervals along the first direction, the elastic member 20 is located between the support 60 and the first latch 10, and the two ends of the elastic member 20 abut against the support 60 and the first latch 10 respectively.
[0130] By adopting the above scheme, it is convenient to restrict the position of the elastic element 20, and the elastic element 20 can apply a force along the first direction to the first locking tongue 10.
[0131] The switch lock structure also includes a sliding member 70, which is connected to the first locking tongue 10 and slidably connected to the support 60. The sliding direction of the sliding member 70 relative to the support 60 is parallel to the first direction.
[0132] By adopting the above scheme, the first locking tongue 10 can move more smoothly in the first and second directions.
[0133] As one possible implementation method, the support 60 is provided with a sliding hole, and the sliding member 70 is slidably inserted into the sliding hole.
[0134] This configuration facilitates connection, with the slider 70 and the support 60 slidably connected.
[0135] Optionally, the elastic element 20 is fitted onto the sliding element 70.
[0136] With this configuration, the position of the elastic element 20 can be restricted by the slider 70, thus preventing the elastic element 20 from bending.
[0137] Optionally, the slider 70 is connected to the limiting member 80, which is located on the side of the support 60 away from the first locking tongue 10, and the limiting member 80 abuts against the support 60.
[0138] With this configuration, the elastic element 20 can apply a force along the first direction to the first latch 10, so that after the first latch 10 extends a certain distance along the first direction, it will prevent the first latch 10 from continuing to extend along the first direction.
[0139] Please refer to Figures 1 to 22 On the other hand, embodiments of this application provide a lock, which includes the switch lock structure as described in the first aspect.
[0140] The lock provided in this application, because the elastic element 20 is used to apply a force along the first direction to the first latch 10 so that the first latch 10 extends along the first direction, and the second latch 30 is spaced apart from the first latch 10; and when the motor is used to drive the moving part to rotate in the actual unlocking direction, the moving part causes the first latch 10 and the second latch 30 to retract together in the second direction, or it can cause the moving part to retract the first latch 10 alone in the second direction. When the motor is used to drive the moving part to move in the actual locking direction, the moving part causes the second latch 30 to extend alone in the first direction. Therefore, the motor can drive the moving part to rotate in different directions, and the detection element can detect the current magnitude of the motor when driving the moving part to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction. Thus, the actual unlocking direction and the actual locking direction of the lock can be configured relatively conveniently, and it is suitable for different installation scenarios.
[0141] It is understood that the lock provided in the embodiments of this application may also include a housing and a control unit. The first latch 10, the second latch 30, the switch assembly, the detection element and the control unit are all disposed inside the housing, and the motor and the detection element are electrically connected to the control unit.
[0142] The lock provided in this application runs automatically after installation and power-on, and can complete automatic configuration in 1-2 seconds, which optimizes the installation process and eliminates the need for tedious operations by installers.
[0143] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
