Technical Field
[0001] The present application belongs to the technical field of security products, and specifically relates to a lock body assembly. Background Art
[0002] In the field of security products, lock body assemblies are usually used to lock or unlock locked parts. Lock body assemblies can be used in scenes such as door panels.
[0003] In the related art, the lock body assembly includes a lock base plate, a driving source, a lever and a lock tongue, wherein the driving source, the lever and the lock tongue are all arranged on the lock base plate, the lock base plate is provided with a lock tongue hole, the lock tongue can extend into the lock tongue hole or extend out of the lock tongue hole, and the lock tongue can rotate relative to the lock base plate, the driving source is connected to the lever, the driving source can drive the lever to rotate, and then the lever acts on the lock tongue to unlock or lock the lock tongue. Specifically, the lever is provided with a sheet metal part, and the sheet metal part is folded into a slide groove with a "U"-shaped structure. When the lever is rotated until the lock tongue extends into the slide groove, the lock tongue and the sheet metal part are limitedly matched, and the lock tongue can no longer rotate relative to the lock base plate, and the locked part is in a locked state; when the lever is rotated until the lock tongue is out of the slide groove, the lock tongue and the sheet metal part are released from the limited cooperation, and the lock tongue can rotate relative to the lock base plate, and then the locked part is unlocked by the rotation of the lock tongue.
[0004] However, since the sheet metal is a bent sheet structure, if the lock body assembly is used for a long time, the impact force of the lock tongue will act on the sheet metal for a long time, which may easily cause the sheet metal to deform, and then cause the slide groove to deform. The slide groove cannot cooperate with the lock tongue for stable limiting, and the use effect of the lock body assembly will be deteriorated. Utility Model Content
[0005] The purpose of the embodiments of the present application is to provide a lock body assembly that can solve the problem of poor use effect of the lock body assembly in the related art.
[0006] The embodiment of the present application provides a lock body assembly, including a lock base plate, a driving source, a toggle block and a first lock tongue, wherein the first lock tongue and the toggle block are both rotatably arranged on the lock base plate, and the rotation position of the toggle block includes a first rotation position and a second rotation position, and the output shaft of the driving source is connected to the lock base plate to drive the toggle block to switch from the first rotation position to the second rotation position relative to the lock base plate.
[0007] When the toggle block is rotated to the first rotation position, the toggle block and the first lock tongue are limited in the rotation direction of the first lock tongue; when the toggle block is rotated to the second rotation position, the toggle block and the first lock tongue are released from the limit cooperation, and the first lock tongue can rotate relative to the lock base plate.
[0008] In the embodiment of the present application, the toggle block can be directly provided with a limiting structure such as a slot or a protrusion to achieve a limiting match with the first lock tongue, and the toggle block is a block-shaped structure. Compared with a sheet metal part with a sheet structure, the toggle block is not easy to bend and deform, so the limiting structure such as a slot or a protrusion provided on the toggle block is not easy to deform, and the toggle block and the first lock tongue can be stably limited and matched, which is conducive to improving the use effect of the lock body assembly. Moreover, the toggle block can directly replace the lever and sheet metal part in the prior art, and the number of parts of the lock body assembly is reduced, which is conducive to simplifying the structure and avoiding large power wear due to more transmission parts.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0032] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0033] The lock body assembly provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.
[0034] Please refer to Figure 1-Figure 12The lock body assembly disclosed in the embodiment of the present application includes a lock base plate 100, a driving source 200, a toggle block 400 and a first lock tongue 300, wherein the lock base plate 100 serves as an installation base for the driving source 200, the toggle block 400 and the first lock tongue 300, the driving source 200 is used to provide rotational power to the toggle block 400, the toggle block 400 is used to lock the first lock tongue 300 or unlock the first lock tongue 300, and the first lock tongue 300 is rotatable relative to the lock base plate 100.
[0035] The first lock tongue 300 is rotatably disposed on the lock substrate 100. Optionally, the first lock tongue 300 can be directly rotatably disposed on the lock substrate 100; or, the first lock tongue 300 can be rotatably disposed on other components, and the other components are connected to the lock substrate 100, so that the first lock tongue 300 is indirectly rotatably disposed on the lock substrate 100.
[0036] The toggle block 400 is rotatably disposed on the lock base plate 100. Optionally, the lock base plate 100 is provided with a rotating shaft, and a shaft hole is provided in the middle position of the toggle block 400. The rotating shaft passes through the shaft hole, and the rotating shaft and the shaft hole are rotatably matched to realize the rotation of the toggle block 400 relative to the lock base plate 100. The rotation position of the toggle block 400 includes a first rotation position and a second rotation position. The output shaft of the driving source 200 is connected to the lock base plate 100 to drive the toggle block 400 to switch from the first rotation position to the second rotation position relative to the lock base plate. The driving source 200 can be a driving member capable of generating rotational power, such as a motor and a pneumatic motor.
[0037] When the toggle block 400 is rotated to the first rotation position, the toggle block 400 cooperates with the first locking tongue 300 in the upper limit position in the rotation direction of the first locking tongue 300. Figure 1 In the state shown, the first locking tongue 300 cannot rotate relative to the locking base plate 100, and the first locking tongue 300 locks the locked member. When the toggle block 400 rotates to the second rotation position, the toggle block 400 and the first locking tongue 300 release the limit fit, refer to Figure 2 In the state shown, the first locking tongue 300 loses the limiting effect of the toggle block 400, and the first locking tongue 300 can rotate relative to the lock base plate 100. At this time, the locked component can be unlocked by rotating the first locking tongue 300.
[0038] That is, the output shaft of the driving source 200 can drive the toggle block 400 to rotate relative to the lock base plate 100, so that the toggle block 400 is separated from the first lock tongue 300, and the toggle block 400 and the first lock tongue 300 are released from the limited fit. It should be noted that the rotation axis of the toggle block 400 is different from the rotation axis of the first lock tongue 300.
[0039] Optionally, the first locking tongue 300 is provided with a first limiting structure, the toggle block 400 is provided with a second limiting structure, and both the first limiting structure and the second limiting structure can be limiting blocks, and the two limiting blocks are limited in cooperation. Of course, the first limiting structure and the second limiting structure can also be other structures, and the embodiment of the present application does not make specific restrictions on this.
[0040] In this embodiment, the toggle block 400 can be directly provided with a limiting structure such as a slot or a protrusion to achieve a limiting match with the first lock tongue 300, and the toggle block 400 is a block structure. Compared with a sheet metal part with a sheet structure, the toggle block 400 is not easy to bend and deform, so the limiting structure such as a slot or a protrusion provided on the toggle block 400 is not easy to deform, and the toggle block 400 and the first lock tongue 300 can be stably limited and matched, which is conducive to improving the use effect of the lock body assembly. Moreover, the toggle block 400 can directly replace the lever and sheet metal parts in the prior art, and the number of parts of the lock body assembly is reduced, which is conducive to simplifying the structure and avoiding large power wear due to more transmission parts.
[0041] In an optional embodiment, the driving source 200 includes a connected housing and an output shaft, the housing is connected to the lock substrate 100, optionally, the housing and the lock substrate 100 can be connected by welding, bonding, etc., the output shaft is connected to the toggle block 400, optionally, the output shaft can be directly connected to the toggle block 400, and the output shaft can also be indirectly connected to the toggle block 400.
[0042] refer to Figure 1-Figure 2 as well as Figure 4-Figure 5 As shown, the first lock tongue 300 and the driving source 200 are both located on the upper side of the toggle block 400, and the housing is adjacent to the toggle block 400. When the toggle block 400 and the first lock tongue 300 are limited and matched, the toggle block 400 is basically in a horizontal state, and the lock tongue and the driving source 200 tend to be arranged in sequence along the horizontal direction. Moreover, in the direction where the rotation axis of the first lock tongue 300 is located, the orthographic projection of the first lock tongue 300 partially overlaps with the orthographic projection of the toggle block 400, and the orthographic projection of the housing partially overlaps with the orthographic projection of the toggle block 400. In this way, the housing and the first lock tongue 300 are not directly arranged at the two ends of the toggle block 400 that are separated from each other, which is conducive to reducing the distance between the housing and the first lock tongue 300, making the housing, the first lock tongue 300 and the toggle block 400 more compact.
[0043] In the embodiment of the present application, the driving source 200 is used to drive the toggle block 400 to rotate to realize the unlocking of the first lock tongue 300. Since the first lock tongue 300 and the driving source 200 are both located on the upper side of the toggle block 400, and the housing of the driving source 200 and the first lock tongue 300 are respectively adjacent to the toggle block 400, the first lock tongue 300 and the driving source 200 only occupy the space on the upper side of the toggle block 400, avoiding occupying the space on both sides of the toggle block 400 at the same time. Moreover, in the direction of the rotation axis of the first lock tongue 300, the first lock tongue The orthographic projection of 300 and the orthographic projection of the casing respectively coincide with the orthographic projection of the toggle block 400, that is, the distance between the first lock tongue 300 and the casing is smaller than the length of the toggle block 400, which effectively reduces the distance between the casing and the first lock tongue 300, making the first lock tongue 300, the toggle block 400 and the driving source 200 more compact and occupying less space, which is also beneficial to reducing the length of the toggle block 400, reducing the torque, reducing power loss, improving power transmission efficiency, and also helping to improve the stability of the lock body assembly.
[0044] Of course, in other embodiments, the first locking tongue 300 and the driving source 200 may be located on different sides of the toggle block 400 , respectively, and the housing and the first locking tongue 300 may be directly disposed at opposite ends of the toggle block 400 .
[0045] In an alternative embodiment, reference Figure 7 , Figure 8 and Fig.10 As shown, one of the first limiting structure and the second limiting structure is a limiting protrusion 310, and the other is a limiting groove 410. The limiting protrusion 310 extends into the limiting groove 410, and the limiting protrusion 310 and the groove wall surface of the limiting groove 410 are matched in the rotation direction of the first locking tongue 300. Optionally, the structure of the limiting protrusion 310 is the same as that of the limiting groove 410. With this embodiment, the limiting protrusion 310 and the limiting groove 410 are used to achieve limiting matching, and the matching area of the limiting protrusion 310 and the limiting groove 410 is large, so that the contact area between the first locking tongue 300 and the toggle block 400 is large, which is conducive to improving the stability in the limiting matching state.
[0046] Optionally, the toggle block 400 is an integrated structure, and a limiting groove 410 is directly formed at one end of the toggle block 400 close to the first locking tongue 300 .
[0047] In an optional embodiment, the number of the first limiting structure and the number of the second limiting structure are both one.
[0048] In another embodiment, the number of the first limiting structures is at least two, wherein the two first limiting structures are arranged opposite to each other, and any one of the first limiting structures can cooperate with the second limiting structure in limiting position. Fig.10As shown, the first lock tongue 300 is provided with a plurality of limiting protrusions 310, and two limiting protrusions 310 are arranged opposite to each other in the direction of the rotation axis of the first lock tongue 300. With this embodiment, the first lock tongue 300 can be installed according to user needs, and even if the installation direction of the first lock tongue 300 is changed, the first lock tongue 300 has a suitable first limiting structure and a second limiting structure, so that the first lock tongue 300 has a wider range of application.
[0049] In an optional embodiment, the lock body assembly further includes a transmission gear 500, which is rotatably disposed on the lock base plate 100. Optionally, the lock body assembly further includes a square shaft 930, which penetrates the lock base plate 100 and is rotatable relative to the lock base plate 100. The transmission gear 500 is sleeved on the outside of the square shaft 930, and the transmission gear 500 is rotatably matched with the square shaft 930. The output shaft of the driving source 200 is provided with a plurality of first meshing teeth along its circumference. Optionally, a gear can be directly sleeved on the outside of the output shaft so that the gear directly forms a first meshing tooth, and the first meshing tooth is meshed with the transmission gear 500.
[0050] like Fig.11 and Fig.12 As shown, the transmission gear 500 is provided with a force-applying protrusion 510. Figure 8 and Fig. 9 As shown, the toggle block 400 is provided with a wedge surface 420, and the force-applying protrusion 510 can be against the wedge surface 420. When the driving source 200 is working, the transmission gear 500 is driven to rotate, and the transmission gear 500 drives the toggle block 400 to rotate relative to the lock base plate 100 through the force-applying protrusion 510 and the wedge surface 420. Optionally, the wedge surface 420 can be a plane or an inclined surface, as long as the force-applying protrusion 510 can drive the toggle block 400 to rotate through the wedge surface 420; the transmission gear 500 is provided with an opening, and a rivet is directly set at the opening, and the rivet protrudes from the surface of the transmission gear 500, and the rivet directly forms the force-applying protrusion 510.
[0051] With this embodiment, during the process of the rotational power of the output shaft of the driving source 200 being transmitted to the toggle block 400 through the transmission gear 500, the form of the rotational power does not change. Compared with the conversion process of rotational power-linear power-rotational power in the prior art, the power transmission is simpler, which is beneficial to improving the power transmission efficiency. Moreover, there is no need for too many power transmission components, and the structure of the lock body assembly is simplified.
[0052] In an optional embodiment, the force-applying protrusion 510 directly acts on the wedge surface 420, that is, the force-applying protrusion 510 can directly contact the wedge surface 420; or Fig.11 and Fig.12As shown, the lock body assembly further includes a roller 511, which is sleeved on the outside of the force-applying protrusion 510, and the force-applying protrusion 510 and the roller 511 are rotatably matched, and the force-applying protrusion 510 is pressed against the wedge surface 420 through the roller 511. Compared with the previous embodiment, the friction form between the force-applying protrusion 510 and the wedge surface 420 in the latter embodiment is changed from sliding friction to rolling friction, which is beneficial to reducing friction, improving the smoothness of relative motion, reducing power loss, and improving power transmission efficiency.
[0053] In an optional embodiment, the transmission gear 500 is provided with an arc-shaped opening 520, and the rotation axis of the transmission gear 500 passes through the center of the arc-shaped opening 520. The lock body assembly further includes a stopper 700, which is connected to the lock substrate 100 and extends into the arc-shaped opening 520. The stopper 700 and the wall surface of the arc-shaped opening 520 are limited in the rotation direction of the transmission gear 500. Optionally, the stopper 700 can be a stopper column, one end of which is connected to the lock substrate 100, and the other end of which passes through the arc-shaped opening 520. During the rotation of the transmission gear 500, the stopper column moves along the extension direction of the arc-shaped opening 520, and the stopper column is respectively limited in the two end walls of the arc-shaped opening 520.
[0054] In this embodiment, the arc-shaped opening 520 and the stopper 700 are used to limit the rotation angle of the transmission gear 500, thereby preventing the transmission gear 500 from rotating excessively and preventing the transmission gear 500 and the shifting block 400 from rotating too much and affecting other components.
[0055] In the scheme of this application, if Figure 4 As shown, the lock body assembly also includes a second lock tongue 940, which is movably disposed on the lock base plate 100. Optionally, the lock base plate 100 can be provided with a first strip-shaped opening, and the second lock tongue 940 is provided with a cylindrical protrusion, which extends into the first strip-shaped opening, and the cylindrical protrusion can move along the length direction of the first strip-shaped opening, so that the second lock tongue 940 can be movable relative to the lock base plate 100; moreover, the second lock tongue 940 is transmission-connected with the transmission gear 500. Optionally, a rack is provided between the transmission gear 500 and the second lock tongue 940, and the transmission gear 500 can be directly meshed with the rack, and the rack is connected to the second lock tongue 940, and the rotational power of the transmission gear 500 is converted into the moving power of the rack, and then the rack drives the second lock tongue 940 to move.
[0056] In the process that the driving source 200 drives the second locking tongue 940 to move through the transmission gear 500 to unlock the second locking tongue 940, the force-applying protrusion 510 abuts against the wedge surface 420. That is, in the process of unlocking the second locking tongue 940, the force-applying protrusion 510 cooperates with the wedge surface 420, the toggle block 400 rotates to release the limited cooperation between the toggle block 400 and the first locking tongue 300, and the second locking tongue 940 is unlocked before the first locking tongue 300. Optionally, the lock base plate 100 is provided with a lock slot, and the second locking tongue 940 can extend from the lock slot or extend into the lock slot. When the second locking tongue 940 is in the unlocked state, the second locking tongue 940 extends into the lock slot.
[0057] Optionally, the first locking tongue 300 can be an oblique tongue, and the second locking tongue 940 can be a square tongue. The oblique tongue is used to locate the locking position of the square tongue, so the square tongue must be unlocked before the oblique tongue, to ensure that the oblique tongue is unlocked after the square tongue is successfully unlocked, to prevent the problem of difficulty in unlocking the square tongue due to the oblique tongue being unlocked first.
[0058] According to this embodiment, the second lock tongue 940 is positioned by using the first lock tongue 300, which is conducive to timely unlocking of the second lock tongue 940 and prevents the first lock tongue 300 from being unlocked before the second lock tongue 940, causing the second lock tongue 940 to get stuck.
[0059] Of course, in other embodiments, the first locking tongue 300 and the second locking tongue 940 can be unlocked at the same time, that is, when the driving source 200 drives the second locking tongue 940 to move through the transmission gear 500 to unlock the second locking tongue 940 , the force applying protrusion 510 abuts against the wedge surface 420 .
[0060] In an optional embodiment, the lock body assembly further includes a first elastic member 800, a first end of the first elastic member 800 is connected to the lock base plate 100, a second end of the first elastic member 800 is connected to the toggle block 400, and the first elastic member 800 can drive the toggle block 400 to switch from the second rotation position to the first rotation position relative to the lock base plate 100, that is, the first elastic member 800 drives the toggle block 400 to rotate relative to the lock base plate 100 to a position that is limited and matched with the first lock tongue 300. In other words, after the driving action of the driving source 200 on the toggle block 400 is lost, the elastic force of the first elastic member 800 is the main force, the first elastic member 800 restores the elastic deformation and drives the toggle block 400 to rotate and reset, so that the toggle block 400 and the first lock tongue 300 are limited and matched again.
[0061] With this embodiment, the elastic force generated by the first elastic member 800 is used to directly drive the toggle block 400 to reset, without the need to set up an electric or pneumatic drive member and then control it separately, making the driving process simpler.
[0062] Of course, in other embodiments, the lock body assembly may not be provided with the first elastic member 800, and the lock body assembly may be provided with other types of driving members such as electric or pneumatic driving members to drive the toggle block 400 to reset, or the lock body assembly may rely on an external driving member to drive the toggle block 400 to reset.
[0063] In an optional embodiment, the first elastic member 800 may be directly a spring, one end of the spring is connected to the lock base plate 100 , and the other end of the spring is connected to the toggle block 400 .
[0064] In another embodiment, reference Figure 8 and Fig. 9 As shown, the first elastic member 800 is a torsion spring, the toggle block 400 is provided with a fixed protrusion 430, the fixed protrusion 430 can be an integrated structure with the toggle block 400, the torsion spring includes a first elastic portion 810, a sleeve portion 820 and a second elastic portion 830 connected in sequence, the sleeve portion 820 is sleeved on the outside of the fixed protrusion 430, the first elastic portion 810 is connected to the lock substrate 100, optionally, the first elastic portion 810 can be directly connected to the lock substrate 100, or the first elastic portion 810 can be indirectly connected to the lock substrate 100; the second elastic portion 830 is against the toggle block 400. That is to say, the first elastic portion 810 is fixed relative to the lock substrate 100, the sleeve portion 820 and the second elastic portion 830 are both fixed relative to the position of the toggle block 400, the sleeve portion 820 and the second elastic portion 830 rotate with the toggle block 400, so the angle between the first elastic portion 810 and the second elastic portion 830 changes, and the first elastic member 800 generates elastic deformation.
[0065] This embodiment directly adopts a torsion spring to directly change the angle between the first elastic part 810 and the second elastic part 830 during the rotation of the toggle block 400. In the subsequent process of restoring the angle between the first elastic part 810 and the second elastic part 830, it is helpful to accurately drive the toggle block 400 to rotate and reset.
[0066] In the solution of the present application, the lock body assembly also includes a mobile base 600, and the first lock tongue 300 is rotatably connected to the mobile base 600. Optionally, one of the first lock tongue 300 and the mobile base 600 is provided with an arc groove 620, and the other is provided with an arc protrusion 320, the arc protrusion 320 extends into the arc groove 620, and the arc protrusion 320 is rotatably matched with the arc groove 620. The rotation axis of the first lock tongue 300 is the axis of the arc protrusion 320, and the arc protrusion 320 can rotate in the arc groove 620 to achieve relative rotation of the first lock tongue 300 and the mobile base 600. Further optionally, reference Fig.10 As shown, the first locking tongue 300 is provided with an arc-shaped protrusion 320, referring to Figure 3As shown, the movable base 600 is provided with an arc groove 620; moreover, the movable base 600 is slidably connected to the lock substrate 100. Optionally, the movable base 600 is provided with a strip protrusion 610, and the lock substrate 100 is provided with a second strip opening 110. The strip protrusion 610 extends into the second strip opening 110, and the strip protrusion 610 and the second strip opening 110 are slidably matched to realize that the movable base 600 can slide relative to the lock substrate 100.
[0067] When the first lock tongue 300 and the toggle block 400 are released from the limited position cooperation, the first lock tongue 300 can rotate relative to the movable base 600, and the first lock tongue 300 can drive the movable base 600 to move relative to the lock base 100. Optionally, the lock base 100 is provided with a first opening, and the first lock tongue 300 extends out of the first opening. When the first lock tongue 300 and the toggle block 400 are released from the limited position cooperation, the first lock tongue 300 can drive the movable base 600 to move relative to the lock base 100, so that the first lock tongue 300 extends into the first opening.
[0068] It should be noted that the first lock tongue 300 is provided with a limiting protrusion 310, and the toggle block 400 is provided with a limiting groove 410, which is a strip groove. The limiting protrusion 310 can be slidably matched with the limiting groove 410, that is, even if the first lock tongue 300 and the toggle block 400 are limitedly matched, it will not affect the movement of the first lock tongue 300 and the movable base 600 relative to the lock base plate 100.
[0069] In this embodiment, by providing the movable base 600 , the first locking tongue 300 can be supported and the first locking tongue 300 can be conveniently driven to move after the limit fit is released, so as to further unlock the first locking tongue 300 .
[0070] In an optional embodiment, the lock body assembly further includes a second elastic member 910, which may be but is not limited to a locking member, a first end of the second elastic member 910 is connected to the lock substrate 100, and a second end of the second elastic member 910 is connected to the movable base 600. When the first lock tongue 300 and the toggle block 400 are released from the limited fit, and the first lock tongue 300 drives the movable base 600 to move relative to the lock substrate 100, the second elastic member 910 generates elastic deformation. Optionally, the lock body assembly further includes a baffle 920, which is connected to the lock substrate 100. The first end of the second elastic member 910 and the baffle 920 can be fixedly connected by welding, bonding, etc., the second end of the second elastic member 910 and the movable base 600 can also be fixedly connected by welding, bonding, etc., and the first elastic portion 810 of the first elastic member 800 and the baffle 920 are fixedly connected by welding, bonding, etc.
[0071] By adopting this embodiment, the elastic force generated by the second elastic member 910 is used to directly drive the movable base 600 and the first lock tongue 300 to reset, which is beneficial for the first lock tongue 300 to move again to a position where it can cooperate with the toggle block 400 for limiting. There is no need to set up an electric or pneumatic drive member and control it separately, making the driving process simpler.
[0072] Of course, in other embodiments, the lock body assembly may not be provided with the second elastic member 910, and the lock body assembly may be provided with other types of driving members such as electric or pneumatic driving members to drive the mobile base 600 to reset, or the lock body assembly may rely on an external driving member to drive the mobile base 600 to reset.
[0073] In summary, the output shaft of the driving source 200 can drive the transmission gear 500 to rotate around Figure 1 The force-applying projection 510 acts on the wedge surface 420 of the toggle block 400, thereby driving the toggle block 400 to rotate clockwise. Figure 1 The toggle block 400 is rotated counterclockwise in the middle, and the toggle block 400 is separated from the first locking tongue 300, so that the limiting protrusion 310 and the limiting groove 410 are released from the limiting cooperation. In this process, the first elastic member 800 generates elastic deformation; after the driving action of the driving source 200 is lost, the elastic force of the first elastic member 800 is the main force, and the first elastic member 800 gradually recovers the elastic deformation and drives the toggle block 400 to rotate around Figure 2 The first locking tongue 300 is gradually approached by rotating the toggle block 400 clockwise until the limiting groove 410 and the limiting protrusion 310 are again limited and matched.
[0074] The lock body assembly can be applied to a door panel. Optionally, the first lock tongue 300 can be an inclined tongue in the prior art, and the inclined tongue includes an inclined surface. When the inclined tongue rotates to the locking position (i.e., the first rotation rod position mentioned above), the toggle block 400 cooperates with the inclined tongue in the upper limit position in the rotation direction of the inclined tongue, and the inclined tongue is restricted from rotating. At this time, the inclined tongue extends into the lock groove of the door frame, and the inclined surface cooperates with the groove wall surface of the lock groove to achieve locking of the door panel; when the inclined tongue rotates to the unlocking position (i.e., the second rotation position mentioned above), the toggle block 400 and the inclined tongue release the limit position cooperation in the rotation direction of the inclined tongue, and the inclined surface is inclined relative to the groove wall surface of the lock groove. At this time, under the action of external force pushing the door panel, the inclined tongue can move relative to the door panel along the inclined surface to achieve unlocking of the door panel. Of course, the lock body assembly can also be applied to other places.
[0075] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
