[0062] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0063] For technologies, methods, and devices known to those of ordinary skill in the relevant fields, they may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0064] In the description of the present application, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary statements, these orientation words do not indicate or imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0065] In the description of the present application, it should be understood that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present application.

[0066] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0067] The incubator can keep the items stored inside warm. Therefore, it is widely used in the fields of biomedicine and the like. For example, some low-temperature incubators are used to store medical biological samples to maintain the activity of the medical biological samples by continuously providing the required low-temperature environment, which is convenient for medical tests or medical research.

[0068] In order to make the incubator have good airtightness and prevent the internal hot air or cold air from leaking out, affecting the heat preservation effect, the incubator is usually provided with a tightening lock, and the tightening locking function of the tightening lock is used to achieve a relatively tight locking effect.

[0069] However, in the related art, the tightening lock generally can only be manually tightened and locked, which is time-consuming and laborious and inconvenient to use. In particular, for a medical incubator, medical staff often wear gloves when operating the lock, and it is very difficult to operate the lock through the gloves, and it is also easy to drop the lock, causing personal injury or damage to items, affecting the use experience.

[0070] In view of the above situation, the present application provides a lock, a lock system and a control method to solve the problem of inconvenient use of the lock on the locked device such as the incubator.

[0071] Figures 1 - 11 Exemplarily, the lock system, lock and control method of the present application are shown.

[0072] Among them, Figure 1 and Figure 2 show the structure of the lock system.

[0073] See Figure 1And Figure 2 In the present application, the lock system 100 includes a device to be locked 20 and a lock 10.

[0074] The device to be locked 20 includes a first component 201 and a second component 202 to be locked. The first component 201 and the second component 202 are movably connected (e.g., rotatably connected) to move between an open position and a closed position for opening and closing. As an example, the device to be locked 20 is an incubator 203, the first component 201 is one of the box body 204 and the box door 205 of the incubator 203, and the second component 202 is the other of the box body 204 and the box door 205 of the incubator 203.

[0075] The lock 10 is provided on the device to be locked 20 for locking and unlocking the first component 201 and the second component 202.

[0076] Figures 3 - 9 The structure of the lock 10 is further shown.

[0077] See Figures 3 - 9 and in combination with Figure 1 and Figure 2 It can be known that in the present application, the lock 10 includes a first locking device 1, a second locking device 2, and an automatic driving mechanism 4. Among them, the first locking device 1 is provided on the first component 201 of the device to be locked 20 and includes a locking member 12. The second locking device 2 is provided on the second component 202 of the device to be locked 20 and includes a pressing portion 23. The pressing portion 23 is movably provided relative to the locking member 12 and gradually engages with the locking member 12 during the movement along the first direction X relative to the locking member 12 to achieve the locking between the first component 201 and the second component 202. The automatic driving mechanism 4 is drivingly connected to at least one of the pressing portion 23 and the locking member 12 to automatically drive the pressing portion 23 to move along the first direction X relative to the locking member 12.

[0078] Since the lock 10 has a pressing portion 23 and relies on the gradual engagement between the pressing portion 23 and the locking member 12 during the movement of the pressing portion 23 along the first direction X relative to the locking member 12 to achieve the locking between the first component 201 and the second component 202 of the device to be locked 20, the lock 10 is a pressing type lock. And because the lock 10 not only includes a pressing portion 23 and a locking member 12, but also includes an automatic driving mechanism 4, and the automatic driving mechanism 4 can automatically drive the pressing portion 23 to move along the first direction X relative to the locking member 12, the pressing type lock 10 can realize an automated pressing locking process, which is time-saving, labor-saving, convenient and fast compared with the manually implemented pressing locking process.

[0079] It can be seen that the above solution can effectively improve the convenience of using the lock 10, thus solving the problem of inconvenient use of the lock on the locked device 20 such as the incubator 203 and effectively improving the user experience. In particular, it helps to prevent the risk of difficulty in unlocking and locking due to reasons such as the user wearing gloves, or even dropping the lock, resulting in personal injury or damage to items such as medical biological samples.

[0080] Among them, the tightening part 23 is an important part of the tightening type lock 10. It usually has variable dimensional characteristics in the first direction X, so that during the movement along the first direction X relative to the locking member 12, the distance between it and the locking member 12 changes from large to small, forcing a fitting relationship between the locking member 12 and the tightening part 23 to change from loose to tight, thereby realizing the tightening and locking function and achieving a relatively tight and reliable locking effect. In some embodiments, the tightening part 23 and the locking member 12 can rotate relative to each other, so as to gradually tighten by rotating the tightening part 23 relative to the locking member 12 along the first direction X.

[0081] Exemplarily, referring to Figure 8 and Figure 9 , the tightening part 23 includes a tightening surface 231. The tightening surface 231 is inclined along the first direction X, so that during the movement of the locking member 12 along the tightening surface 231 in the second direction Y opposite to the first direction X, the fit between it and the tightening surface 231 gradually changes from loose to tight, and finally forms a tightening connection to realize tightening and locking. When unlocking is required, it only needs to move the tightening surface 231 relative to the locking member 12 in the second direction Y, so that the fit between the two gradually changes from tight to loose, and the tightening connection can be easily released to realize reverse unlocking.

[0082] Among them, the tightening surface 231 may include a tightening curved surface 232 (refer to Figure 8 and Figure 9 ) or a tightening plane. The tightening curved surface 232 and the tightening plane are respectively a curved surface and a plane with tightening characteristics, which can conveniently realize the tightening and locking effect. In particular, compared with the tightening plane, the tightening curved surface 232 can not only perform tightening and locking based on the overall inclination, but also strengthen the tightening effect based on its own curve change. Therefore, it is beneficial to achieve a more reliable tightening and locking effect.

[0083] Continuing to refer to Figure 8 and Figure 9, in some embodiments, a recess 233 is provided on the tightening surface 231, and the recess 233 is located between the two ends of the tightening surface 231 along the first direction X. In this way, when the locking member 12 moves relative to the tightening surface 231 to the recess 233, the acting force between the tightening surface 231 and the locking member 12 will change suddenly. For example, during the locking process, when reaching the recess 233, the acting force between the locking member 12 and the tightening curved surface 232 will suddenly decrease. For another example, during the unlocking process, when reaching the recess 233, the acting force between the locking member 12 and the tightening curved surface 232 will suddenly increase. In this way, it is convenient to judge whether the locking or unlocking is about to be completed during the locking and unlocking processes. For example, during the locking process, it can be judged whether the tightening lock is about to be completed by feeling whether the tightening force suddenly decreases. For another example, during the unlocking process, it can be judged whether the reverse unlocking is completed by feeling whether the tightening force suddenly increases.

[0084] It should be noted that the structural form of the tightening portion 23 is not limited to the tightening surface 231. For example, as a variant, the tightening portion 23 may include a tightening groove. Wherein, the width of the tightening groove can become smaller from large along the second direction Y, so as to achieve the tightening locking effect by gradually clamping with the tightening groove during the movement of the locking member 12 along the tightening groove in the second direction Y.

[0085] In addition, as Figure 8 and Figure 9 shown, in some embodiments, a stop portion 24 is provided at the starting end of the tightening portion 23 along the first direction X to stop the locking member 12. In this way, the stop portion 24 can be used to limit the displacement of the locking member 12 relative to the tightening portion 23 to prevent over-tightening.

[0086] In the foregoing embodiments, the automatic driving mechanism 4 can be drivingly connected to at least one of the tightening portion 23 and the locking member 12 to automatically drive the tightening portion 23 to move relative to the locking member 12 along the first direction X. That is, the automatic driving mechanism 4 can be drivingly connected to only one of the tightening portion 23 and the locking member 12, or drivingly connected to both the tightening portion 23 and the locking member 12 at the same time.

[0087] As an example, referring to Figures 5 - 9 , the automatic driving mechanism 4 is drivingly connected to the tightening portion 23 to drive the tightening portion 23 to move relative to the locking member 12 along the first direction X by driving the tightening portion 23 to move along the first direction X. Based on this, the tightening portion 23 can move while the locking member 12 remains stationary, and the locking member 12 can be guided by the tightening portion 23 during the movement to gradually reach the position where it is clamped with the tightening portion 23, realizing the tightening locking process, which is simple and convenient and has a good tightening effect.

[0088] Specifically, continue to refer to Figures 5 - 9, in some embodiments, the second locking device 2 includes a support base 22 and a mounting base 21. The mounting base 21 is used to connect with the second component 202. The support base 22 is movably arranged on the mounting base 21. A pressing part 23 is arranged on the support base 22. The automatic driving mechanism 4 is drivingly connected with the support base 22 to drive the pressing part 23 to move along the first direction X by driving the support base 22 to move along the first direction X. In this way, only by driving the support base 22 to move along the first direction X by the automatic driving mechanism 4 can the pressing and locking be realized, which is simple and convenient. Among them, the provided mounting base 21 also facilitates the installation and fixation of the second locking device 2 on the second component 202, so as to facilitate the realization of the pressing and locking function when the second locking device 2 is firmly installed.

[0089] As an example of the automatic driving mechanism 4 drivingly connected with the support base 22, refer to Figures 5 - 6 and Figures 8 - 9 , the automatic driving mechanism 4 includes a power mechanism 41, a first transmission device 42 and a second transmission device 43. The second transmission device 43 is arranged on the support base 22. The power mechanism 41 is drivingly connected with the second transmission device 43 through the first transmission device 42 to drive the support base 22 to move along the first direction X. In this way, the power of the power mechanism 41 can be transmitted to the support base 22 via the first transmission device 42 and the second transmission device 43, and then the support base 22 drives the pressing part 23 to move to realize pressing and locking or reverse unlocking, which is simple and convenient.

[0090] Among them, refer to Figure 8 and Figure 9 , in some embodiments, the power mechanism 41 includes a motor 44. At this time, the automatic driving mechanism 4 is an electric driving mechanism, which can conveniently drive the pressing part 23 to cooperate with the locking member 12 for pressing and locking or reverse unlocking when powered on.

[0091] In addition, refer to Figure 8 and 9 , in some embodiments, the first transmission device 42 includes one of a gear 45 and a rack 46 that mesh with each other, and the second transmission device 43 includes the other of the gear 45 and the rack 46 that mesh with each other. At this time, the automatic driving mechanism 4 relies on the cooperation of the gear 45 and the rack 46 for power transmission, with high transmission accuracy, which is convenient for realizing a more precise pressing and locking and reverse unlocking process. Moreover, it is also convenient to limit the displacement of the gear 45 along the first direction X by designing the length of the rack 46, so as to better cooperate with the pressing part 23 to realize the required pressing and locking and reverse unlocking process.

[0092] Continue to refer to Figure 8 and Figure 9, in some embodiments, at least one end of the rack 46 along the first direction X is provided with a limiting portion 47 to limit the displacement of the gear 45. Based on this, the limiting portion 47 can limit the displacement of the support base 22 and the pressing portion 23 along the first direction X and / or the second direction Y by limiting the position of the gear 45, preventing the gear 45 from rotating excessively and causing problems.

[0093] In addition, referring to Figure 3 and Figure 9 , in some embodiments, a collision prevention member 25 is provided between the support base 22 and the mounting base 21. When the support base 22 moves in place along the first direction X, the support base 22 and the mounting base 21 contact through the collision prevention member 25. In this way, it is possible to prevent the support base 22 and the mounting base 21 from colliding violently during the operation of the lock 10 and causing problems, especially preventing the internal structure of the lock 10 from being damaged due to the failure of the lock 10 during operation.

[0094] As a further improvement to the foregoing embodiments, referring to Figure 3 , in some embodiments, the lock 10 not only includes the first locking device 1, the second locking device 2, and the automatic driving mechanism 4, but also includes a sensing portion 6. The sensing portion 6 is disposed on the first locking device 1 or the second locking device 2 and is signal-connected to the automatic driving mechanism 4 to trigger the automatic driving mechanism 4 to start when a sensing object is sensed. Among them, the sensing object of the sensing portion 6 may include a fingerprint and / or a sensing card (such as an ID card). In this way, during use, the user can use swiping a fingerprint and / or a sensing card on the sensing portion 6 as an input signal for starting the automatic driving mechanism 4, so that the automatic driving mechanism 4 can respond in time when the user needs to lock or unlock the door, effectively meeting the user's usage requirements. Moreover, since the user only needs to swipe a fingerprint and / or a sensing card to lock or unlock the door, it is more time-saving and labor-saving, and can more effectively improve the user experience.

[0095] In addition, referring to Figure 2 and Figure 10 , in the foregoing embodiments, the lock 10 may further include a detection member 5. The detection member 5 is disposed on the first component 201 or the second component 202 and detects the distance between the first component 201 and the second component 202. The automatic driving mechanism 4 is coupled to the detection member 5 to start and stop according to the detection result of the detection member 5. In this way, the distance information between the first component 201 and the second component 202 detected by the detection member 5 can be used as a basis for starting and stopping the automatic driving mechanism 4, enabling the automatic driving mechanism 4 to drive to complete the locking and unlocking process more timely and accurately.

[0096] Among them, based on the distance information between the first component 201 and the second component 202 detected by the detection component 5, it can be determined whether the automatic driving mechanism 4 needs to be started, and which direction among the first direction X and the second direction Y the driving pressing part 23 moves relative to the locking part 12 after starting, and it can be determined whether the automatic driving mechanism 4 can stop during the process of driving the pressing part 23 to move relative to the locking part 12 in the first direction X or the second direction Y.

[0097] For example, in some embodiments, the distance S when the first component 201 and the second component 202 are closed but not yet locked is determined as the preset distance S, and the start and stop control of the automatic driving mechanism 4 is performed according to whether the distance between the first component 201 and the second component 202 detected by the detection component 5 is greater than the corresponding preset distance S.

[0098] Among them, before starting to lock and unlock, if the distance between the first component 201 and the second component 202 is less than the preset distance S, it means that the first component 201 and the second component 202 are in the locked state. Therefore, in this case, if a trigger signal from the user is received (for example, the user swipes a card or fingerprints on the sensing part 6), it means that the user needs to unlock, so the automatic driving mechanism 4 can be started, and the automatic driving mechanism 4 drives the pressing part 23 to move relative to the locking part 12 along the second direction Y to unlock the first component 201 and the second component 202; if the distance between the first component 201 and the second component 202 is greater than or equal to the preset distance S, it means that the first component 201 and the second component 202 are in the unlocked state. Therefore, in this case, if a trigger signal from the user is received, it means that the user needs to lock, so the automatic driving mechanism 4 can be started, and the automatic driving mechanism 4 drives the pressing part 23 to move relative to the locking part 12 along the first direction X to lock the first component 201 and the second component 202. It can be seen that the start and the driving direction of the automatic driving mechanism 4 can be controlled according to the detection signal of the detection component 5 and the signal of the sensing part 6, and thus whether to lock and unlock can be controlled.

[0099] During the process of locking and unlocking the lock, the detection signal of the detection component 5 can be used to determine whether the lock 10 has been locked or unlocked in place, and then control whether the automatic driving mechanism 4 needs to be shut down. Among them, during the unlocking process, if it is detected that the distance between the first component 201 and the second component 202 changes from being originally less than the preset distance S to being greater than or equal to the preset distance S, it indicates that the unlocking is in place. Therefore, the automatic driving mechanism 4 can be shut down, so that the automatic driving mechanism 4 no longer drives the pressing portion 23 to move relative to the locking member 12 along the second direction Y, ending the corresponding unlocking process; and during the locking process, if it is detected that the distance between the first component 201 and the second component 202 changes from being originally greater than or equal to the preset distance S to being less than the preset distance S, it indicates that the locking is in place. Therefore, the automatic driving mechanism 4 can be shut down, so that the automatic driving mechanism 4 no longer drives the pressing portion 23 to move relative to the locking member 12 along the first direction X, ending the corresponding locking process.

[0100] In addition, the detection result of the detection component 5 can not only be used as the basis for starting and stopping the automatic driving mechanism 4, but also can be used as the indication information for abnormal situations, so as to detect abnormal situations in time and remind the user to handle them. For example, referring to Figure 10 , in some embodiments, the lock 10 not only includes the detection component 5, but also includes an alarm 82. The alarm 82 alarms when the detection component 5 detects that the distance between the first component 201 and the second component 202 is greater than or equal to the preset distance S and exceeds the preset time T. Among them, the distance between the first component 201 and the second component 202 being greater than or equal to the preset distance S and exceeding the preset time T indicates that the first component 201 and the second component 202 have not been locked for a long time. Since this situation may cause problems such as deterioration or inactivation of the stored items, it is necessary to remind the user to handle it in time. With the cooperation of the detection component 5 and the alarm 82, the abnormal situation that the first component 201 and the second component 202 have not been locked for a long time can be detected in time and the user is reminded to handle it. Therefore, the operating safety of the lock system 100 can be effectively improved, and the user experience can be further improved.

[0101] It can be seen that setting the detection component 5 to feedback the switching state between the first component 201 and the second component 202 can further improve the convenience and safety of use, which cannot be achieved by the purely manual pressing lock in the related art.

[0102] Referring to Figure 11In some embodiments, the signal transmission among the detection member 5, the automatic driving mechanism 4, the alarm 82, and the sensing portion 6 is all implemented by the controller 81. The controller 81 realizes the signal connection between the detection member 5 and the sensing portion 6 and the automatic driving mechanism 4, and realizes the signal connection between the detection member 5 and the alarm 82, so as to control the operation of the automatic driving mechanism 4 according to the signals of the detection member 5 and the sensing portion 6, and control the operation of the alarm 82 according to the signal of the detection member 5.

[0103] In addition, to further improve the convenience of using the lock 10, refer to Figures 1 - 8 In some embodiments, the lock 10 not only includes the automatic driving mechanism 4, but also includes a manual driving mechanism 3. The manual driving mechanism 3 is drivingly connected to at least one of the pressing portion 23 and the locking member 12 to manually drive the pressing portion 23 to move relative to the locking member 12 along the first direction X. In this way, the lock 10 can not only realize the automatic pressing and locking process, but also realize the manual pressing and locking process, with higher working flexibility, which is convenient for the user to select one of the manual and automatic pressing methods according to the actual situation. Especially when the automatic driving mechanism 4 fails to work normally due to power failure or other reasons, the manual driving mechanism 3 can be used to manually lock and unlock the door, so that the lock 10 can still be locked and unlocked in case of power failure or other situations, and will not be unable to work, affecting the normal use of the locked device 20.

[0104] Next, a further introduction will be made to Figures 1 - 11 the structure and working process of the lock system and its lock shown.

[0105] As Figures 1 - 10 shown, in this embodiment, the lock system 100 includes a locked device 20 and a lock 10.

[0106] As Figure 1 and 2 shown, in this embodiment, the locked device 20 is an incubator 203, and the first component 201 and the second component 202 to be locked of the locked device 20 are the box body 204 and the box door 205 respectively. The box door 205 is rotatably connected to the box body 204 to realize the opening and closing processes during rotation.

[0107] The lock 10 is disposed on the incubator 203 and is used to press the box door 205 tightly after the box door 205 is closed to prevent cold leakage. As Figures 3 - 10 shown, in this embodiment, the lock 10 includes a first locking device 1, a second locking device 2, a manual driving mechanism 3, an automatic driving mechanism 4, a detection member 5, a sensing portion 6, a controller 81, and an alarm 82.

[0108] Among them, the first locking device 1 is arranged on the box body 204 and includes a base 11 and a locking member 12. The base 11 is arranged on the box body 204, and the locking member 12 is arranged on the base 11. In this way, the installation and fixation of the locking member 12 on the box body 204 can be realized.

[0109] Specifically, in combination with Figure 2 and Figure 3 it can be known that in this embodiment, the base 11 is generally semi-circular, and it is installed on the side surface of the box body 204 through threaded members (such as bolts), etc., and is close to the opening of the box body 204, so that the first locking device 1 is arranged on the side surface of the box body 204 and close to the opening of the box body 204, which is convenient for the locking member 12 of the first locking device 1 to cooperate with the pressing portion 23 of the second locking device 2 for pressing and locking.

[0110] The locking member 12 is arranged on the surface of the base 11 away from the side surface of the box body 204 and protrudes in a direction away from the box body 204, so as to extend into the second locking device 2 and contact the pressing portion 23 of the second locking device 2. As Figure 3 shown, in this embodiment, the locking member 12 is generally columnar and includes a shaft body 13 and a shaft sleeve 14. The shaft body 13 is connected to the base 11. The shaft sleeve 14 is rotatably sleeved outside the shaft body 13. In this way, it is convenient for the locking member 12 to cooperate with the pressing portion 23 which is the pressing curved surface 232 of the second locking device 2 to realize pressing and locking. Among them, the shaft sleeve 14 can rotate, which is beneficial to reducing the resistance during the sliding process of the locking member 12 along the pressing curved surface 231, and further facilitating the realization of the pressing and locking function.

[0111] The second locking device 2 is arranged on the box door 205 and includes a mounting seat 21, a support seat 22, an end cover 71, a pressing plate 72 and a wear-resistant member 73. The support seat 22 is provided with a pressing portion 23, a stop portion 24 and a shock-proof member 25.

[0112] Among them, in combination with Figures 2 - 4 it can be known that in this embodiment, the mounting seat 21 is arranged on the side surface of the box door 205 to realize the installation of the second locking device 2 on the side surface of the box door 205. Specifically, as Figure 3 and Figure 4 shown, in this embodiment, the mounting seat 21 includes a boss 211 and a plugging portion 212.

[0113] The boss 211 is generally semi-circular, and is connected to the side surface of the door 205 at the free end through a connecting member such as a bolt, so as to realize the installation and fixation of the mounting seat 21 and the second locking device 2 on the side surface of the free end of the door 205. In this embodiment, the semi-circular boss 211 has its flat surface facing the pressing surface 223, and its cross-sectional area is smaller than that of the insertion portion 212 and the inner cavity 221. In this way, the boss 211 can avoid the locking member 12, so that the locking member 12 can be inserted into the support seat 22 and contact the pressing portion 23 for pressing and locking.

[0114] The insertion portion 212 is generally cylindrical, and is connected to the side of the boss 211 away from the side surface of the door 205, and protrudes away from the side surface of the door 205, so as to be inserted into the support seat 22 and cooperate with the support seat 22 to realize the rotatable connection of the support seat 22 relative to the mounting seat 21. And, as Figure 3 shown, in this embodiment, a groove 213 is provided at one end of the insertion portion 212 away from the boss 211, and the end of the groove 213 away from the boss 211 is open, so that as Figure 6 shown, when the insertion portion 212 is inserted into the support seat 22, it can cooperate with the pressure plate 72 and the support seat 22 to enclose and form a first cavity 222, providing an installation space for the arrangement of other structures such as the automatic driving mechanism 4. At the same time, as Figure 3 known, in this embodiment, an anti-collision member 25 is provided on the insertion portion 212. The anti-collision member 25 has elasticity and can absorb impact, reduce vibration and noise. Furthermore, during the pressing and locking process or in case of failure, it can reduce the collision intensity between the support seat 22 and the mounting seat 21 and lower the risk of component damage due to collision.

[0115] The support seat 22 is rotatably arranged on the mounting seat 21, and the pressing portion 23 is arranged on the support seat 22, so that the support seat 22 can drive the pressing portion 23 to rotate, so as to realize the rotation of the pressing portion 23 relative to the locking member 12, achieving the purposes of pressing and locking and reverse unlocking.

[0116] As Figure 3 shown, in this embodiment, the support seat 22 is generally annular and has an inner cavity 221 for the insertion portion 212 to be inserted. The insertion portion 212 is inserted into the inner cavity 221, so that the support seat 22 is sleeved outside the insertion portion 212 and can rotate. As Figure 5 shown, after the insertion portion 212 is inserted into the support seat 22, it cooperates with the support seat 22 and the pressure plate 72 to enclose and form a first cavity 222. At the same time, a second cavity 223 is enclosed between the boss 211 and the inner wall of the support seat 22. The second cavity 223 is open towards the locking member 12 and is not blocked by the side surface of the door 205, so that the locking member 12 can be inserted into the second cavity 223 and cooperate with the pressing portion 23.

[0117] And, back to Figure 3, a wear-resistant member 73 is provided between the support base 22 and the insertion portion 212. Specifically, a wear-resistant member 73 is provided at each of the end portions of the insertion portion 212 close to and away from the boss 211, so that two wear-resistant members 73 are provided between the support base 22 and the insertion portion 212. Both of these two wear-resistant members 73 are located between the outer wall of the insertion portion 212 and the inner wall of the support base 22, so that the insertion portion 212 and the support base 22 do not directly contact, but contact through the two wear-resistant members 73. Among them, both the support base 22 and the mounting base 21 are made of metal materials, while the two wear-resistant members 73 are both made of nylon materials. In this way, during the rotation of the support base 22 relative to the mounting base 21, the two wear-resistant members 73 can prevent the inner wall of the support base 22 from directly contacting and rubbing against the outer wall of the insertion portion 212, thereby preventing problems such as powder shedding, noise, and rust caused by friction between metals. If the support base 22 and the mounting base 21 made of metal materials directly contact and rub, it is easy to generate powder, and it is easy to damage the coating, resulting in rust, and at the same time, it is easy to generate relatively large noise. After the wear-resistant members 73 are provided, the corresponding problems can be effectively solved, so that the lock 10 can achieve a more silent, safe, and smooth locking and unlocking process.

[0118] Among them, a protrusion is provided on the wear-resistant member 73 at the end portion of the insertion portion 212 away from the boss 211, which is used to be embedded in the groove of the insertion portion 212 to press the pressing plate 72 and the insertion portion 212 tightly. At the same time, as Figure 3 shown, in this embodiment, an end cover 71 is provided at one end of the support base 22 away from the boss 211. The end cover 71 covers the port at one end of the support base 22 away from the boss 211 to close the corresponding port. A pressing plate 72 is provided between the end cover 71 and the port of the support base 22. The pressing plate 72 is connected to the mounting base 21 through the wear-resistant member 73 at the end portion of the insertion portion 212 away from the boss 211.

[0119] Among them, as Figure 3 shown, in this embodiment, the structures of the two wear-resistant members 73 are the same, and both are in the shape of an open ring, forming an open ring gasket. The wear-resistant member 73 is set to be an open non-full-circle ring shape, and the advantage is that materials can be saved and the rotation resistance can be reduced.

[0120] As Figure 5 and Figure 8 and Figure 9As shown, in this embodiment, the tightening portion 23 is a tightening surface 232. The tightening surface 232 is provided on the inner wall of the support base 22 and extends along the circumferential direction of the support base 22. Along the first direction X, the tightening surface 232 is inclined, and the distance between the tightening surface 232 and the corresponding outer wall of the support base 22 gradually decreases. In other words, along the second direction Y, the distance between the tightening surface 232 and the outer wall of the support base 22 gradually increases. In this way, when the tightening surface 232 rotates along the first direction X together with the support base 22, the locking member 12 rotates along the second direction Y relative to the tightening surface 232. Then, the locking member 12 gradually climbs onto the tightening surface 232 and, under the guidance of the tightening surface 232, gradually climbs along the tightening surface 232. The contact between the locking member 12 and the tightening surface 232 gradually changes from loose to tight and finally forms a tightening and hanging connection, achieving the effect of tightening and locking. On the contrary, when the tightening surface 232 rotates along the second direction Y together with the support base 22, the contact between the locking member 12 and the tightening surface 232 gradually becomes loose and finally separates from the tightening surface 232, achieving the effect of reverse unlocking.

[0121] It can be seen from Figure 8 and Figure 9 that in this embodiment, a stop portion 24 is provided at the starting end of the tightening surface 232 along the first direction X (which is also the ending end along the second direction Y). The stop portion 24 protrudes radially inward relative to the tightening surface 232, so that when the tightening surface 232 moves in place along the first direction X and the locking member 12 reaches the starting end of the tightening surface 232 along the first direction X, the locking member 12 can abut against the stop portion 24 and be blocked by the stop portion 24, and stop moving relative to the tightening surface 232 along the second direction Y to prevent over-tightening and causing structural damage.

[0122] Moreover, as Figure 8 and Figure 9 shown, in this embodiment, a concave portion 233 is provided between the two ends of the tightening surface 232. The concave portion 233 is recessed radially outward, which is convenient for feeling whether it is tightened, especially for the user to feel whether it is tightened during the manual locking and unlocking process. The concave portion 233 is relatively small and will not block the sliding of the locking member 12 along the tightening surface 232.

[0123] The manual driving mechanism 3 is provided on the second locking device 2 and is used to achieve the manual driving of the tightening portion 23 to realize the manual tightening process. As Figures 1 - 8As shown, in this embodiment, the manual driving mechanism 3 is arranged on the support base 22 and includes a handle 31. The handle 31 is generally annular, and its two ends are fixed to the outer wall of the support base 22 to realize the installation and fixation of the manual driving mechanism 3 on the second locking device 2. When the handle 31 is rotated, the support base 22 can be driven to rotate, so that the tightening part 23 rotates relative to the locking part 12 in the first direction X or the second direction Y, realizing the manual tightening and locking or reverse unlocking process. In this embodiment, when the handle 31 is rotated by 45°, the tightening and locking or reverse unlocking can be completed.

[0124] The automatic driving mechanism 4 is arranged on the second locking device 2 and is located in the first cavity 222 for realizing the automatic driving of the tightening part 23 to realize the automatic tightening process. As Figures 5 - 9 shown, in this embodiment, the automatic driving mechanism 4 is an electric driving mechanism, which includes a motor 44, a gear 45 and a rack 46. The motor 44 serves as the power mechanism 41, and the gear 45 and the rack 46 serve as the first transmission device 42 and the second transmission device 43 respectively. The rack 46 is arranged on the inner wall of the support base 22 and meshes with the gear 45, and the gear 45 is drivingly connected to the motor 44. After the motor 44 is started, the support base 22 can be driven through the gear 45 and the rack 46 to drive the tightening part 23 to rotate. When the motor 44 rotates forward and backward, the support base 22 can be driven to drive the tightening part 23 to rotate in the first direction X or the second direction Y, realizing the tightening and locking or reverse unlocking. Among them, from Figure 8 and Figure 9 it can be seen that in this embodiment, limiting parts 47 are provided at both ends of the rack 46 along the first direction X for limiting the reciprocating displacement of the gear 45 to prevent excessive rotation. And the rack 46 and the tightening part 23 are respectively located on the opposite sides of the circumference of the support base 22. In this way, the layout is reasonable, which is convenient for the arrangement of the automatic driving mechanism 4 and the tightening part 23, and is also convenient for the automatic driving mechanism 4 and the tightening part 23 to work independently without interference. And, as Figure 5 shown, in this embodiment, the rack 46 and the tightening part 23 are axially offset from each other on the support base 22. The rack 46 is located in the first cavity 222 formed by the insertion part 212 and the support base 22, and the tightening part 23 is located in the second cavity 223 formed by the boss 211 and the support base 22. In this way, it is also convenient for the rack 46 and the tightening part 23 to cooperate with the gear 45 and the locking part 12 respectively.

[0125] The sensing part 6 is used to sense the sensing object and provide a trigger signal for the start of the automatic driving mechanism 4. As Figure 3 shown, in this embodiment, the sensing part 6 is arranged on the handle 31 and is a fingerprint and ID card integrated sensing slot, which can sense both fingerprints and ID cards, so that when the user swipes fingerprints or ID cards, a trigger signal can be provided for the automatic driving mechanism 4. Among them, as Figure 10As shown, in this embodiment, the sensing unit 6 is signal - connected to the controller 81, and the controller 81 is signal - connected to the automatic driving mechanism 4. Specifically, the controller 81 is signal - connected to the motor 44. In this way, when the user swipes a fingerprint or a card, the sensing unit 6 can transmit a signal to the controller 81. After being processed by the controller 81, the corresponding signal is transmitted to the motor 44. When the conditions are appropriate, the motor 44 is controlled to start for automatic locking and unlocking operations.

[0126] The detection member 5 is used to detect the distance between the box door 205 and the box body 204 to determine the door state, which is used as the basis for whether to lock or unlock the door and whether to give an alarm. As Figure 2 shown, in this embodiment, the detection member 5 is arranged on the box body 204 and includes a displacement sensor 51. The displacement sensor 51 is arranged at one end of the box body 204 with an opening, and is used to detect the distance between the box door 205 and the box body 204. And, as Figure 10 shown, in this embodiment, the displacement sensor 51 is signal - connected to the controller 81, and the controller 81 is signal - connected to the motor 44 and the alarm 82. In this way, the coupling between the displacement sensor 51, the alarm 82 and the motor 44 can be realized, so that the detection signal of the displacement sensor 51 can be transmitted to the motor 44 and the alarm 82 after being processed by the controller 81 to control the operation of the motor 44 and the alarm 82.

[0127] Figure 11 Shows the working process of the lock 10 in this embodiment.

[0128] As Figure 11 shown, when the automatic driving mechanism 4 can work normally, for example, when the automatic driving mechanism 4 has no mechanical failure and the lock system 100 is normally powered, the automatic driving mechanism 4 drives the pressing part 23 and the locking part 12 to rotate relative to each other, and during the corresponding process, the detection member 5 monitors and feeds back the distance between the box door 205 and the box body 204 in real time.

[0129] Among them, if the detection member 5 continuously detects that the distance between the box door 205 and the box body 204 is greater than or equal to the preset distance S for more than the preset time T (for example, 3 min), the alarm 82 will give an alarm to prompt the user to close and lock the door to eliminate the corresponding abnormal situation.

[0130] When the abnormal situation is eliminated, or when there is no corresponding abnormal situation, if the user swipes a card or a fingerprint, an automatic locking operation or an automatic unlocking operation will be performed respectively according to the detection result of the detection member 5.

[0131] Specifically, when swiping a card or fingerprint, if the detection member 5 detects that the distance between the box door 205 and the box body 204 is greater than or equal to the preset distance S, the controller 81 controls the motor 44 to rotate forward. The support seat 22 is driven by the gear 45 and the rack 46 to drive the tightening portion 23 and the handle 31 to rotate along the first direction X for tightening and locking. During the corresponding tightening and locking process, the detection member 5 continuously detects the distance between the box door 205 and the box body 204. When it is detected that the distance between the box door 205 and the box body 204 becomes less than the preset distance S, it is determined that the lock 10 has been locked in place, and then the motor 44 stops rotating forward. Otherwise, the motor 44 continues to rotate forward. When swiping a card or fingerprint, if the detection member 5 detects that the distance between the box door 205 and the box body 204 is less than the preset distance S, the controller 81 controls the motor 44 to rotate in reverse. The support seat 22 is driven by the gear 45 and the rack 46 to drive the tightening portion 23 and the handle 31 to rotate along the second direction Y for reverse unlocking. During the corresponding reverse unlocking process, the detection member 5 continuously detects the distance between the box door 205 and the box body 204. When it is detected that the distance between the box door 205 and the box body 204 becomes greater than or equal to the preset distance S, it is determined that the lock 10 has been opened in place, and then the motor 44 stops rotating in reverse. Otherwise, the motor 44 continues to rotate in reverse.

[0132] When the automatic driving mechanism 4 can work normally, the lock 10 can be cycled to lock and unlock in the above manner. During the automatic locking and unlocking process, after one unlocking (or locking) operation, if the user swipes the card or fingerprint again, the reverse action can be defaulted to perform the locking (or unlocking) operation.

[0133] When the automatic driving mechanism 4 cannot work normally, for example, when the automatic driving mechanism 4 has its own mechanical failure or the lock system 100 is powered off, the above automatic control method fails. The lock can be operated by manually rotating the handle 31.

[0134] Regardless of the manual tightening and locking process or the automatic tightening and locking process, in order to enable the locking member 12 to stably maintain at the tightening and locking position, the lock 10 may further include a locking mechanism to limit the displacement of the locking member 12 after the locking member 12 reaches the tightening and locking position and prevent the locking member 12 from accidentally leaving the tightening and locking position. Among them, the locking mechanism may include a locking tongue and a lock catch that cooperate with each other, and the locking tongue can be manually driven and / or electrically driven to achieve the corresponding manual and / or electric tightening and positioning process. The more specific structure of the locking mechanism is not the focus of the improvement of this application and can adopt the existing structure. Therefore, it will not be elaborated here.

[0135] It can be seen that the lock system 100 and its lock 10 of this embodiment have a simple structure, are convenient to use, and are safe and flexible. Among them, the detection member 5 can be used to feedback the on / off state of the device to be locked in real time, and the automatic locking and unlocking process can be controlled by fingerprint or card swiping, which saves time and effort. It can effectively solve the problem that the locks of devices to be locked such as the incubator 203 can only be manually tightened, which is time-consuming and laborious, and cannot automatically sense the on / off state and open and close the door in real time. Moreover, in the case of power failure or the like, the lock can also be manually locked and unlocked, which does not affect the normal use of the lock 10, and has stronger flexibility and higher safety.

[0136] See Figure 11 , based on the lock 10 of the foregoing embodiments, the present application further provides a control method, which includes:

[0137] Judge whether the automatic driving mechanism 4 can work normally;

[0138] When the automatic driving mechanism 4 can work normally, the automatic driving mechanism 4 automatically drives the tightening part 23 and the locking part 12 to move relative to each other.

[0139] In some embodiments, the automatic driving of the tightening part 23 and the locking part 12 by the automatic driving mechanism 4 to move relative to each other includes:

[0140] Judge whether there is a trigger signal, and detect the distance between the first component 201 and the second component 202;

[0141] When there is a trigger signal, and the distance between the first component 201 and the second component 202 is greater than or equal to the preset distance S but does not exceed the set time T, the automatic driving mechanism 4 drives the tightening part 23 to move along the first direction X relative to the locking part 12 to lock the first component 201 and the second component 202;

[0142] When there is a trigger signal, and the distance between the first component 201 and the second component 202 is less than the preset distance S, the automatic driving mechanism 4 drives the tightening part 23 to move along the second direction Y opposite to the first direction X relative to the locking part 12 to unlock the first component 201 and the second component 202.

[0143] In some embodiments, during the process that the automatic driving mechanism 4 drives the tightening part 23 to move relative to the locking part 12 along the first direction X to lock the first component 201 and the second component 202, when it is detected that the distance between the first component 201 and the second component 202 is less than the preset distance S, the automatic driving mechanism 4 is made to stop driving the tightening part 23 to move relative to the locking part 12 along the first direction X; and / or, during the process that the automatic driving mechanism 4 drives the tightening part 23 and the locking part 12 to move relative to each other along the second direction Y to unlock the first component 201 and the second component 202, when it is detected that the distance between the first component 201 and the second component 202 is greater than or equal to the preset distance S, the automatic driving mechanism 4 is made to stop driving the tightening part 23 to move relative to the locking part 12 along the second direction Y.

[0144] In addition, in some embodiments, the control method further includes:

[0145] Determining whether the distance between the first component 201 and the second component 202 is greater than or equal to the preset distance S and exceeds the preset time T;

[0146] In the case that the distance between the first component 201 and the second component 202 is greater than or equal to the preset distance S and exceeds the preset time T, an alarm is given.

[0147] The above are only exemplary embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
