Description

Technical Field

[0001] This application relates to the technical field of locks, and particularly to a control method for a switch lock structure, a switch lock structure, and a lock. Background Art

[0002] With the development of technology, various locks have emerged, and locks are also 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 currently is a scheme of a backpack motor and a mechanical lock body. Specifically, the backpack motor rotates to drive the lock tongue of the lock body to extend / retract to achieve locking and unlocking. Since the opening directions of users' doors are different, the door lock may be installed on the left or right side of the door. Therefore, in these two cases, the rotation directions of the backpack motor driving the lock body to lock and unlock are opposite.

[0003] Since the lock can only be set with a default unlocking direction when leaving the factory, it needs to be configured according to the specific situation after installation at the user end. The current conventional method is to power on and try out after installing the lock to observe whether the default unlocking direction and the default locking direction are normal. If abnormal, enter the motor function setting by inputting a specific instruction on the door lock button panel, and then select the motor rotation direction according to the relevant prompts to set the actual unlocking direction and the actual locking direction. After setting, verify and check whether it is normal. The entire process requires the installer to try out, observe, configure, and verify, and the entire configuration process is cumbersome. Summary of the Invention

[0004] This application provides a control method for a switch lock structure, a switch lock structure, and a lock, which can more conveniently configure the actual unlocking direction and the actual locking direction of the lock.

[0005] In a first aspect, an embodiment of this application provides a control method for a switch lock structure. The switch lock structure includes:

[0006] A first lock tongue;

[0007] An elastic member for applying a force in a first direction to the first lock tongue so that the first lock tongue extends in the first direction;

[0008] A second lock tongue, which is arranged at an interval from the first lock tongue;

[0009] A switch assembly, comprising a motor and a moving member connected in transmission. When the motor is used to drive the moving member to rotate in the actual unlocking direction, the moving member drives the first lock tongue and the second lock tongue to retract together in a second direction, and the moving member can drive the first lock tongue to retract alone in the second direction. The second direction is opposite to the first direction. When the motor is used to drive the moving member to rotate in the actual locking direction, the moving member drives the second lock tongue to extend alone in the first direction. The actual unlocking direction is opposite to the actual locking direction;

[0010] A detecting member, configured to detect the magnitude of the current corresponding to the motor when driving the moving member to rotate;

[0011] The control method includes:

[0012] Use the motor to drive the moving member to rotate from the initial position in the default unlocking direction, and stop rotating when the current value detected by the detecting member is greater than the stall threshold;

[0013] Use the motor to drive the moving member to rotate in the default locking direction to the initial position. The default locking direction is opposite to the default unlocking direction;

[0014] Use the motor to drive the moving member to rotate from the initial position in the default locking direction, and stop rotating when the current value detected by the detecting member is greater than the stall threshold;

[0015] Use the motor to drive the moving member to rotate in the default unlocking direction to the initial position;

[0016] Use the motor to drive the moving member to rotate from the initial position in the default locking direction, and stop rotating when the current value d detected by the detecting member is greater than the stall threshold, and obtain the duration t during which d is greater than the preset threshold c;

[0017] If t is greater than the first preset time T1, set the default unlocking direction as the actual locking direction, and set the default locking direction as the actual unlocking direction. Otherwise, set the default unlocking direction as the actual unlocking direction, and set the default locking direction as the actual locking direction.

[0018] In some embodiments, the preset threshold c and the first preset time T1 are obtained by the following method:

[0019] Obtain a first current value a corresponding to the motor when the motor drives the moving part to rotate and the first lock tongue and the second lock tongue are not in contact with the moving part, and a second current value b corresponding to the motor and the required time T0 when the motor drives the moving part to rotate so that the moving part drives the first lock tongue to retract alone along the second direction, and set 1 / 2 of T0 as the first preset time T1;

[0020] The preset threshold c=a+(ba) / 2 is calculated.

[0021] In some embodiments, the step of using the motor to drive the moving member to rotate toward the default locking direction to the initial position includes:

[0022] Using the motor 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 at the initial position;

[0023] Alternatively, the switch lock structure further includes a sensor switch, and the motor is used to drive the moving part to rotate toward the default locking direction until the moving part triggers the sensor switch, and at this time the moving part is located at the initial position.

[0024] In some embodiments, the step of using the motor to drive the moving part to rotate toward the default unlocking direction to the initial position includes:

[0025] Using the motor to drive the moving part to rotate in the default unlocking direction for a third preset time T3, at which time the moving part is located at the initial position;

[0026] Alternatively, the switch lock structure further includes a sensor switch, and the motor is used to drive the moving part to rotate toward the default unlocking direction until the moving part triggers the sensor switch, and at this time the moving part is located at the initial position.

[0027] In a second aspect, an embodiment of the present application provides 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 toggle part connected to each other, the rotating part is transmission-connected to the motor, and the toggle part is used to rotate together with the rotating part around the axis of the rotating part to toggle the first lock tongue and the second lock tongue.

[0029] In some of the embodiments, the rotating portion is disposed on a side of the second locking tongue facing away from the first locking tongue;

[0030] The first locking tongue comprises a first portion and a second portion connected to each other, the first portion extends along the first direction, and one end of the first portion away from the second portion extends along the first direction, the extending direction of the second portion is arranged at an angle to the first direction, and one end of the second portion away from the first portion extends in a direction close to the second locking tongue, and the toggle portion is used to toggle the second portion;

[0031] And / or, the second lock tongue includes a third part and a fourth part connected to each other, the third part extends along the first direction, and an end of the third part away from the fourth part is used to extend along the first direction, the extension direction of the fourth part is set at an angle to the first direction, and an end of the fourth part away from the first part extends in a direction close to the first lock tongue, and the toggle part is used to toggle the fourth part.

[0032] In some embodiments, the switch lock structure also includes a support, and the support and the first lock tongue are arranged in sequence and at intervals along the first direction. The elastic member is located between the support and the first lock tongue, and two ends of the elastic member are respectively abutted against the support and the first lock tongue.

[0033] In some embodiments, the switch lock structure further includes a sliding member, the sliding member is connected to the first lock tongue, the sliding member is slidably connected to the support, and the sliding direction of the sliding member relative to the support is parallel to the first direction.

[0034] In a third aspect, an embodiment of the present application provides a lock, which includes the switch lock structure as described in the second aspect.

[0035] The switch lock structure provided in the embodiment of the present application has the beneficial effect that: since the elastic member is used to apply a force along the first direction to the first lock tongue, so that the first lock tongue extends along the first direction, and the second lock tongue is spaced apart from the first lock tongue; and when the motor is used to drive the moving member to rotate in the actual unlocking direction, the moving member drives the first lock tongue and the second lock tongue to retract together in the second direction, or can drive the first lock tongue to retract alone in the second direction, and when the motor is used to drive the moving member to move in the actual locking direction, the moving member drives the second lock tongue to extend alone in the first direction, so the moving member can be driven to rotate in different directions by the motor, and the detection member can detect the current corresponding to the motor when driving the moving member to rotate, so as to determine whether the default unlocking direction is the same 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, which is suitable for different installation scenarios.

[0036] For the beneficial effects of the control method and the lock of the switch lock structure provided in this application compared with the prior art, reference can be made to the description of the beneficial effects of the switch lock structure provided in this application compared with the prior art, which will not be elaborated here.

[0072] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0074] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0075] Referring to "one embodiment", "some embodiments" or "embodiments" in the description of the present application means that specific features, structures or characteristics described in combination with the embodiment are included in one or more embodiments of the present application. Thus, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" and the like appearing in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless otherwise specifically emphasized in another way. In addition, in one or more embodiments, specific features, structures or characteristics can be combined in any suitable manner.

[0076] In order to illustrate the technical solutions of the present application, the following will be described with reference to specific drawings and embodiments.

[0077] With the development of technology, various types of locks have emerged, and locks 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 currently is a solution with a backpack motor and a mechanical lock body. Specifically, the backpack motor rotates to drive the lock tongue of the lock body to extend / retract to achieve locking and unlocking. Since the opening directions of users' doors vary, the door lock may be installed on the left or right side of the door. Therefore, in these two cases, the rotation directions of the backpack motor driving the lock body to lock and unlock are opposite.

[0078] Since the lock can only be set with a default unlocking direction when leaving the factory, it needs to be configured according to the specific situation after installation at the user end. The current conventional method is to power on and test after installing the lock to observe whether the default unlocking direction and the default locking direction are normal. If abnormal, enter the motor function setting by inputting a specific instruction on the door lock button panel, and then select the motor rotation direction according to the relevant prompts to set the actual unlocking direction and the actual locking direction. After setting, verify and check whether it is normal. The entire process requires the installer to test, observe, configure, and verify, and the entire configuration process is cumbersome.

[0079] In view of this, the present application provides a control method for a locking and unlocking structure, a locking and unlocking structure, and a lock. Since the elastic member is used to apply a force along the first direction to the first lock tongue so that the first lock tongue extends along the first direction, the second lock tongue is spaced apart from the first lock tongue; and the motor is used to drive the moving member to rotate in the actual unlocking direction so that the moving member drives the first lock tongue and the second lock tongue to retract together along the second direction, or can make the moving member drive the first lock tongue alone to retract along the second direction, and the motor is used to drive the moving member to move in the actual locking direction so that the moving member drives the second lock tongue alone to extend along the first direction. Therefore, the motor can be driven to rotate the moving member in different directions, and the corresponding current magnitude when the motor drives the moving member is detected by the detection member 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, which is applicable to different installation scenarios.

[0080] Please refer to Figure 1 in (a) and Figure 1 in (b). In the first aspect, an embodiment of the present application provides a control method for a locking and unlocking structure. The locking and unlocking structure is used for a lock, and the lock includes a control unit (such as a main control chip, etc.) and a locking and unlocking structure. The locking and unlocking structure includes a first lock tongue 10, a second lock tongue 30, a switching component, and a detection member (not shown in the figure).

[0081] The elastic member 20 is used to apply a force along the first direction to the first lock tongue 10 so that the first lock tongue 10 extends along the first direction.

[0082] The elastic member 20 may be a spring, elastic rubber or elastic silicone etc. The first direction may be Figure 1 The direction indicated by the arrow H.

[0083] The second locking tongue 30 is spaced apart from the first locking tongue 10 .

[0084] The first locking tongue 10 may be an oblique tongue, and the second locking tongue 30 may be a square tongue.

[0085] The switch assembly includes a motor (not shown in the figure) and a moving part connected in a transmission manner. When the motor is used to drive the moving part to rotate in the actual unlocking direction, the moving part drives the first lock tongue 10 and the second lock tongue 30 to retract together in the second direction, and the moving part can drive the first lock tongue 10 to retract alone in 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 is used to drive the moving part to rotate toward the actual locking direction, the moving part drives the second locking tongue 30 to extend alone along the first direction, and the actual unlocking direction and the actual locking direction are opposite to each other.

[0086] The rotation direction of the motor and the rotation direction of the rotating member can be the same or opposite. In the illustrated embodiment, the rotation direction of the motor and the rotation direction of the rotating member 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 part is used to detect the corresponding current size when the motor drives the moving part to rotate.

[0088] The detection component may include an AdC (Analog to digital Converter) of the control unit. Both the control unit and the detection component may be electrically connected to the motor. The control unit may control the motor to rotate in different directions. The control unit may also include a timer and the like.

[0089] After the lock having the switch lock structure provided by the above embodiment is installed, the initially set rotation direction of the moving part includes a default unlocking direction and a default locking direction 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 actually required, the second lock tongue 30 may extend or retract, and the first lock tongue 10 will be in an extended state in both cases due to the force of the elastic member 20. Therefore, it is necessary to confirm the relationship between the two and make corresponding configurations.

[0090] In the traditional method, installers need to conduct trials, observations, configurations, and verifications. The entire process is cumbersome. However, for the switch lock structure provided in this application, the current magnitude corresponding to the motor driving the moving part can be detected by the detection component 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.

[0091] Please also refer to Figures 1 to 22 , the control method for the switch lock structure provided in the embodiment of this application includes:

[0092] First, use the motor to drive the moving part to rotate from the initial position in the default unlocking direction, and stop rotating when the current value detected by the detection component is greater than the stall threshold.

[0093] In Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 14 , Figure 16 , Figure 18 , Figure 20 and Figure 22 , the unit of the abscissa can be seconds, and the unit of the ordinate can be amperes.

[0094] Specifically, the stall threshold can be the current value corresponding to the stall of the moving part. When the moving part stalls, it cannot continue to rotate. As Figure 2 shown, at this time, the moving part abuts against the second lock tongue 30.

[0095] It should be noted that although the trends of the corresponding relationship diagrams of the current value and time in each figure are generally the same, the current of the motor when driving the oblique tongue and the square tongue to move simultaneously is larger than that of the motor when driving in a single driving mode.

[0096] Second, use the motor to drive the moving part to rotate in the default locking direction to the initial position. The default locking direction is the opposite direction of the default unlocking direction.

[0097] Third, use the motor to drive the moving part to rotate from the initial position in the default locking direction, and stop rotating when the current value detected by the detection component is greater than the stall threshold.

[0098] Then, use the motor to drive the moving part to rotate in the default unlocking direction to the initial position.

[0099] Next, use the motor to drive the moving part to rotate from the initial position in the default locking direction, and stop rotating when the current value d detected by the detection component is greater than the stall threshold. Obtain the duration t during which d is greater than the preset threshold c in this process. t can be directly detected by the timer of the control unit or obtained by separately setting a timer.

[0100] Wherein, 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 specifically to Figures 1 to 11 , after installing the lock with the switch lock structure provided in the above embodiment, when the default unlocking direction is the same as the actual unlocking direction actually required, such as in the Figures 8 to 10 shown stage, when using the motor to drive the moving part to rotate from the initial position towards the default locking direction and stop rotating when the current value d detected by the detecting part is greater than the stall threshold, and obtaining the duration t during which d is greater than the preset threshold c in this process, the motor will idle to the end until the moving part abuts against the second locking tongue 30, d is greater than the stall threshold, and the corresponding working current value d of the motor includes the current value when the motor idles, 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. When the moving part abuts against the second locking tongue 30 and starts to stall, the current d will increase instantaneously during stalling, so the time when d is greater than c is very short, and t is less than T1.

[0102] Please refer specifically to Figures 12 to 22 , when after installing the lock with the switch lock structure provided in the above embodiment, the default unlocking direction is opposite to the actual unlocking direction actually required, such as in the Figures 19 to 21 shown stage, when using the motor to drive the moving part to rotate from the initial position towards the default locking direction and stop rotating when the current value d detected by the detecting part is greater than the stall threshold, and obtaining the duration t during which d is greater than the preset threshold c in this process, the motor will idle for a certain distance and then make the moving part abut against the first locking tongue 10, and then abut against the second locking tongue 30 until it stalls. The corresponding working current value d of the motor includes the current value when the motor idles, 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 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 current value of the motor during stalling are all greater than c, and t is greater than T1.

[0103] Therefore, it can be judged that if t is greater than 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. During this process, the control unit of the lock can automatically judge 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, without manual trial, observation, configuration, and verification, and the whole process is simple to operate.

[0104] As can be seen from the above, for the control method of the switch lock structure provided by the present application, since the elastic member 20 is used to apply a force in the first direction to the first locking tongue 10 so that the first locking tongue 10 extends in the first direction, and the second locking tongue 30 is arranged at an interval from the first locking tongue 10; and when the motor is used to drive the moving member to rotate in the actual unlocking direction, the moving member drives the first locking tongue 10 and the second locking tongue 30 to retract together in the second direction, or the moving member can drive the first locking tongue 10 to retract alone in the second direction, and when the motor is used to drive the moving member to move in the actual locking direction, the moving member drives the second locking tongue 30 to extend alone in the first direction. Therefore, the motor can be used to drive the moving member to rotate in different directions, and the current magnitude corresponding to the motor when driving the moving member is detected by the detecting member, so as to determine whether the default unlocking direction is the same as or opposite to the actual unlocking direction, thereby being able to configure the actual unlocking direction and the actual locking direction of the lock more conveniently and being applicable to different installation scenarios.

[0105] Please refer to Figure 11 and Figure 22 , in this embodiment, the preset threshold value c and the first preset time T1 are obtained in the following manner:

[0106] First, obtain the first current value a corresponding to the motor when the motor drives the moving member to rotate and neither the first locking tongue 10 nor the second locking tongue 30 is in contact with the moving member, and the second current value b corresponding to the motor and the required time T0 when the motor drives the moving member to rotate so that the moving member drives the first locking tongue 10 to retract alone in the second direction, and set 1 / 2 of T0 as the first preset time T1.

[0107] Secondly, calculate the preset threshold value c = a + (b - a) / 2.

[0108] By adopting the above scheme, the preset threshold value c and the first preset time T1 can be obtained more conveniently.

[0109] It should be noted that the first current value a can be the corresponding current value when the motor idles, and the second current value b can be the corresponding current value when the motor drives the moving member to rotate to drive the first locking tongue 10 (the inclined tongue). When the motor rotates to the end and stalls, its corresponding current increases sharply and then stops rotating. Among them, the current when the motor idles is a, and the current of the motor will increase significantly when driving the inclined tongue to retract, which is b. The current a, the current b and the first preset time T1 are affected by different types of motors and lock bodies, and they can be obtained by pre-testing the same type of switch lock structure before leaving the factory.

[0110] Among them, using the motor to drive the moving member to rotate in the default locking direction to the initial position includes:

[0111] Use the motor to drive the moving part to rotate in the default locking direction for a second preset time T2. At this time, the moving part is located at the initial position.

[0112] For example, before the device leaves the factory, T2 can be obtained by pre-testing the same type of switch lock structure.

[0113] Alternatively, the switch lock structure further includes a sensor switch. Use the motor to drive the moving part to rotate in the default locking direction until the moving part triggers the sensor switch. At this time, the moving part is located at the initial position.

[0114] By adopting the above scheme, it is possible to conveniently use the motor to drive the moving part to rotate in the default locking direction to the initial position.

[0115] Among them, using the motor to drive the moving part to rotate in the default unlocking direction to the initial position includes:

[0116] Use the motor to drive the moving part to rotate in the default unlocking direction for a third preset time T3. At this time, the moving part is located at the initial position.

[0117] For example, before the device leaves the factory, T3 can be obtained by pre-testing the same type of switch lock structure.

[0118] Alternatively, the switch lock structure further includes a sensor switch. Use the motor to drive the moving part to rotate in the default unlocking direction until the moving part triggers the sensor switch. At this time, the moving part is located at the initial position.

[0119] By adopting the above scheme, it is possible to conveniently use the motor to drive the moving part to rotate in the default unlocking direction to the initial position.

[0120] Please refer to Figures 1 to 22 In the second aspect, the embodiments of the present application provide a switch lock structure, and the switch lock structure uses the control method as in the first aspect.

[0121] For the switch lock structure provided by the present application, since the elastic member 20 is used to apply a force along the first direction to the first locking tongue 10 so that the first locking tongue 10 extends along the first direction, the second locking tongue 30 is spaced apart from the first locking tongue 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 locking tongue 10 and the second locking tongue 30 to retract together along the second direction, or the moving part can drive the first locking tongue 10 to retract alone along 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 locking tongue 30 to extend alone along the first direction. Therefore, it is possible to drive the moving part to rotate in different directions by the motor, and detect the corresponding current magnitude when the motor drives the moving part through the detecting member, so as 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, which is applicable to different 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 transmission. The toggle part 50 is used to rotate together with the rotating part 40 around the axis of the rotating part 40 to toggle the first lock tongue 10 and the second lock tongue 30.

[0123] By adopting the above solution, it is convenient to use a motor to drive the moving part to rotate in different directions, so that the moving part drives 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, a pulley or a disc, etc., and the motor is used to drive the shifting part 50 and the rotating part 40 to rotate together around the axis of the rotating part 40 .

[0125] Optionally, the rotating portion 40 is disposed on a side of the second locking tongue 30 facing away from the first locking tongue 10 .

[0126] The first locking tongue 10 includes a first portion 11 and a second portion 12 connected to each other. The first portion 11 extends along a first direction, and one end of the first portion 11 away from the second portion 12 extends along the first direction. The extension direction of the second portion 12 is set at an angle to the first direction. One end of the second portion 12 away from the first portion 11 extends along a direction close to the second locking tongue 30. The toggle portion 50 is used to toggle the second portion 12.

[0127] And / or, the second lock tongue 30 includes a third part 31 and a fourth part 32 connected to each other, the third part 31 extends along the first direction, and an 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, and an end of the fourth part 32 away from the first part 11 extends in a direction close to the first lock tongue 10, and the toggle part 50 is used to toggle the fourth part 32.

[0128] Such a configuration can make the structure of the first locking tongue 10 and / or the second locking tongue 30 relatively simple, and facilitate the shifting portion 50 to shift the first locking tongue 10 and the second locking tongue 30 .

[0129] In this embodiment, the switch lock structure also includes a support 60, which is arranged in sequence and at intervals with the first lock tongue 10 along the first direction. The elastic member 20 is located between the support 60 and the first lock tongue 10, and the two ends of the elastic member 20 are respectively abutted against the support 60 and the first lock tongue 10.

[0130] By adopting the above solution, the position of the elastic member 20 is conveniently limited, and the elastic member 20 can apply a force along the first direction to the first locking tongue 10 .

[0131] The switch lock structure further includes a sliding member 70 , which is connected to the first locking tongue 10 , and is slidably connected to the support 60 , and a sliding direction of the sliding member 70 relative to the support 60 is parallel to the first direction.

[0132] By adopting the above solution, the first locking tongue 10 can move more smoothly along the first direction and the second direction.

[0133] As one possible implementation method, the support 60 is provided with a sliding hole, and the sliding member 70 can be slidably inserted into the sliding hole.

[0134] Such arrangement facilitates the connection, and the sliding member 70 is slidably connected to the support 60 .

[0135] Optionally, the elastic member 20 is sleeved on the sliding member 70 .

[0136] With such configuration, the position of the elastic member 20 can be limited by the sliding member 70 to prevent the elastic member 20 from bending.

[0137] Optionally, the sliding member 70 is connected to a limiting member 80 , and the limiting member 80 is located on a side of the support 60 away from the first locking tongue 10 , and the limiting member 80 abuts against the support 60 .

[0138] With such configuration, the elastic member 20 can apply a force along the first direction to the first locking tongue 10 so that after the first locking tongue 10 extends a certain distance along the first direction, the first locking tongue 10 is prevented from continuing to extend along the first direction.

[0139] Please refer to Figures 1 to 22 On the other hand, an embodiment of the present application provides a lock, which includes a switch lock structure as described in the first aspect.

[0140] In the lock provided by the present application, since the elastic member 20 is used to apply a force along the first direction to the first lock tongue 10, so that the first lock tongue 10 extends out along the first direction, and the second lock tongue 30 is spaced apart from the first lock tongue 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 lock tongue 10 and the second lock tongue 30 to retract together in the second direction, or can drive the first lock tongue 10 to retract alone in the second direction, and when the motor is used to drive the moving part to move in the actual locking direction, the moving part drives the second lock tongue 30 to extend out alone in the first direction, so the moving part can be driven to rotate in different directions by the motor, and the detection part can detect the corresponding current size of the motor when driving the moving part, so as to determine whether the default unlocking direction is the same 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, which is suitable for different installation scenarios.

[0141] It can be understood that the lock provided by the embodiments of the present application may further include a housing and a control unit. The first lock tongue 10, the second lock tongue 30, the switch assembly, the detection member, and the control unit are all disposed inside the housing. The motor and the detection member are both electrically connected to the control unit.

[0142] After the lock provided by the present application is installed, it powers on and runs automatically, and can complete automatic configuration in 1 second - 2 seconds, optimizing the installation process and eliminating the need for cumbersome operations by installers.
