Description

Technical Field

[0001] This application belongs to the field of lock technology, specifically relating to a lock body and a door lock. Background Technology

[0002] Door locks, as a key component for ensuring security in various locations, are widely used in different scenarios such as residential and commercial buildings. With the advancement of technology, people have placed higher demands on door locks.

[0003] In traditional designs, door locks typically include components such as a housing, a handle, and a drive shaft. The housing is mounted on the door, the drive shaft is rotatably connected to the housing, and the handle is located outside the housing and is connected to the drive shaft. In use, the user rotates the handle to drive the drive shaft, which in turn moves the bolt of the lock, controlling the opening and closing of the door.

[0004] However, in the above design, the handle is indirectly connected to the cover through a drive shaft. With this arrangement, the weight of the handle and the external forces it receives are mainly applied to the cover, which places high demands on the strength of the cover and results in a limited variety of materials that can be used for the cover. This restricts the further optimization and development of the door lock. Utility Model Content

[0005] The purpose of this application is to provide a lock body and a lock for a door lock, which can solve the problem of the limited types of materials that can be selected for the cover in related technologies.

[0006] In a first aspect, embodiments of this application provide a lock body for connecting to both the door body and the lock housing, the lock body comprising:

[0007] Mounting plate, which is used to connect to both the door body and the cover;

[0008] A drive shaft, at least a portion of which is disposed within the housing and is rotatable relative to the housing, and the drive shaft is rotatably connected to the mounting plate;

[0009] A handle, at least a portion of which is disposed outside the housing and is rotatable relative to the housing, the handle being drively connected to the drive shaft.

[0010] Secondly, this application provides a door lock, which includes a housing and a lock body as described above. The housing is connected to the mounting plate of the lock body. At least a portion of the drive shaft of the lock body is disposed inside the housing, and at least a portion of the handle of the lock body is disposed outside the housing and is rotatable relative to the housing.

[0011] In this embodiment, the handle is connected to the drive shaft, which is rotatably connected to the mounting plate. The mounting plate is used to connect to both the door body and the door lock cover. With this arrangement, the weight of the handle and the external forces it receives are mainly applied to the mounting plate, and the cover does not bear the weight of the handle or the external forces applied to the handle. As a result, the strength requirements for the cover are reduced, which allows for a wider variety of materials to be selected for the cover. Attached Figure Description

[0034] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] The lock body and lock of the door lock provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0037] Please refer to Figures 1 to 12As shown in the embodiment of this application, a lock body for a door lock is provided, which is connected to both the door body 940 and the door lock housing 910. The lock body includes: a mounting plate 100, a drive shaft 200, and a handle 300.

[0038] The mounting plate 100 is used to connect with both the door body 940 and the cover 910.

[0039] At least a portion of the drive shaft 200 is disposed within the housing 910 and is rotatable relative to the housing 910. In other words, the drive shaft 200 may be entirely located within the housing 910 or only partially located within the housing 910, and the drive shaft 200 is rotatably connected to the mounting plate 100.

[0040] At least a portion of the handle 300 is disposed outside the housing 910, and the handle 300 is rotatable relative to the housing 910. That is, the handle 300 may be entirely located outside the housing 910, or a portion of the handle 300 may be located outside the housing 910 and another portion of the handle 300 may be located inside the housing 910. The handle 300 is connected to the drive shaft 200 in a drive connection.

[0041] In this embodiment, the handle 300 is connected to the drive shaft 200, and the drive shaft 200 is rotatably connected to the mounting plate 100. The mounting plate 100 is connected to both the door body 940 and the door lock cover 910. With this arrangement, the weight of the handle 300 and the external forces it receives are mainly applied to the mounting plate 100, and the cover 910 basically does not bear the weight of the handle 300 or the external forces applied to the handle 300. As a result, the strength requirements for the cover 910 are reduced, thereby allowing for a wider variety of materials to be selected for the cover 910.

[0042] In another embodiment, reference Figure 1 and Figure 2 As shown, the lock body also includes a mounting base 400, a transmission component 500, and a clutch mechanism 600. The mounting base 400 is connected to the mounting plate 100, and the transmission shaft 200 is rotatably connected to the mounting base 400. The mounting base 400 serves as the mounting base for the transmission shaft 200, which is rotatably connected to the mounting base 400, thereby indirectly rotatably connected to the mounting plate 100.

[0043] The transmission component 500 is rotatably mounted on the mounting base 400 and is used for transmission connection with the bolt 921 of the door lock to drive the bolt 921 to extend and retract, thereby controlling the opening and closing of the door 940. Optionally, the transmission component 500 may be, for example, a transmission base.

[0044] The clutch mechanism 600 is mounted on the mounting base 400 and is used to engage or disengage the power transmission path between the transmission member 500 and the drive shaft 200. When the clutch mechanism 600 engages the power transmission path between the transmission member 500 and the drive shaft 200, the drive shaft 200 is drivenly connected to the transmission member 500, so that the transmission member 500 rotates synchronously with the drive shaft 200. When the clutch mechanism 600 disengages the power transmission path between the transmission member 500 and the drive shaft 200, the drive shaft 200 can rotate relative to the transmission member 500; in other words, the drive shaft 200 cannot drive the drive shaft 200 to rotate synchronously.

[0045] In this embodiment, the drive shaft 200, the transmission component 500, and the clutch mechanism 600 are all mounted on the mounting base 400. In this way, the drive shaft 200, the transmission component 500, the clutch mechanism 600, and the mounting base 400 are integrated into a whole, which can be disassembled and assembled as a whole, thereby improving the disassembly and assembly efficiency of the lock body. In addition, this integrated design reduces the difficulty of material management and facilitates material management.

[0046] Furthermore, by integrating the drive shaft 200, drive component 500, clutch mechanism 600, and mounting base 400 into one unit, this overall structure can be used as a universal module, adaptable to various door lock models.

[0047] In other embodiments, at least one of the drive shaft 200, the drive component 500, and the clutch mechanism 600 may also be directly mounted on the mounting plate 100.

[0048] As one specific implementation method, refer to Figure 4 As shown, the clutch mechanism 600 includes, for example, a linear drive 610, a clutch fork 620, and a clutch pin 630.

[0049] The linear drive 610 is mounted on the mounting base 400. Optionally, the linear drive 610 is, for example, a push rod motor. The clutch fork 620 has an arc-shaped structure. The driving end of the linear drive 610 is connected to the clutch fork 620 and is used to drive the clutch fork 620 to move closer to or further away from the drive shaft 200 along a first direction, thereby moving between a first position and a second position. The first direction is, for example, perpendicular to the axial direction of the drive shaft 200. The clutch pin 630 slides with the transmission member 500 along the first direction and is connected to the transmission member 500 through a first elastic element, for example, a spring.

[0050] The drive shaft 200 is provided with a notch 211. When the clutch fork 620 is in the first position, the first elastic element is in a compressed state. One end of the clutch pin 630 extends into the notch 211 to engage the power transmission path between the drive member 500 and the drive shaft 200, so that the drive member 500 and the drive shaft 200 are connected by the clutch pin 630. At the same time, the clutch fork 620 contacts the other end of the clutch pin 630 to restrict the clutch pin 630 from moving away from the drive shaft 200. In this state, when the handle 300 is turned, the drive shaft 200 can drive the latch 921 to extend and retract through the drive member 500, so that the door 940 can be opened and closed by turning the handle 300. In addition, in this state, when the drive shaft 200 rotates, the clutch pin 630 rotates synchronously with the drive shaft 200, and the shape of the clutch fork 620 is adapted to the rotation trajectory of the clutch pin 630. During the rotation of the drive shaft 200, the clutch pin 630 is always in contact with the clutch fork 620.

[0051] During the process of the clutch fork 620 moving from the first position to the second position, the clutch fork 620 gradually separates from the clutch pin 630. At the same time, under the action of the first elastic element, the clutch pin 630 resets in the direction away from the transmission shaft 200. During this process, the clutch pin 630 gradually disengages from the notch 211. When the clutch fork 620 is in the second position, the clutch fork 620 is just separated from the clutch pin 630, and the clutch pin 630 is completely disengaged from the notch 211. In this state, the power transmission path between the transmission component 500 and the transmission shaft 200 is disconnected, and the transmission shaft 200 cannot drive the transmission component 500 to rotate. At this time, the rotating handle 300 cannot drive the locking tongue 921 to extend or retract, so the rotating handle 300 cannot control the opening and closing of the door 940.

[0052] Furthermore, the drive shaft 200 is provided with an annular flange 210, which surrounds the drive shaft 200. A notch 211 is provided on the annular flange 210, which provides a basis for the notch 211, thereby reducing the difficulty of setting the notch 211. In addition, the annular flange 210 is detachably connected to a reversing screw 220, and the drive shaft 200 is fitted with a second elastic element 810, which is, for example, a torsion spring. The torsion spring is used to drive the handle 300 to rotate from the unlocked position to the locked position. When the handle 300 is in the unlocked position, the latch 921 retracts, thereby opening the door 940. When the handle 300 is in the locked position, the latch 921 extends, thereby limiting the latch 921 to engage with the door 940, thereby locking the door 940. Additionally, during the rotation of the handle 300 from the locked position to the unlocked position, the reversing screw 220 engages, for example, with one of the torsion arms of the torsion spring to drive the torsion spring to twist and store elastic potential energy. Conversely, the torsion spring releases the previously stored elastic potential energy, thereby driving the handle 300 to automatically return from the unlocked position to the locked position.

[0053] It should be noted that in other embodiments, the clutch mechanism 600 may also take other forms; this embodiment is merely an example. Additionally, in other embodiments, the clutch mechanism 600 may not include the linear drive member 610. In this case, for example, the user needs to manually move the clutch fork 620 to engage or disengage the power transmission path between the first end of the drive shaft 200 and the transmission member 500.

[0054] In another embodiment, the mounting base 400 has a receiving cavity in which the first end of the drive shaft 200, at least a portion of the transmission member 500, and the clutch mechanism 600 are located. The clutch mechanism 600 is used to engage or disengage the power transmission path between the first end of the drive shaft 200 and the transmission member 500. Specifically, the linear drive member 610, clutch fork 620, clutch pin 630, second elastic member 810, and reversing screw 220 mentioned above are all located in the receiving cavity, for example. The door lock also includes a protective shell 700, which is fitted over the mounting base 400. The second end of the drive shaft 200 extends out of the protective shell 700 and is throttle-connected to the handle 300.

[0055] In this embodiment, both the mounting base 400 and the protective shell 700 protect the first end of the drive shaft 200, the portion of the transmission component 500 located in the receiving cavity, and the clutch mechanism 600. Under this dual protection, the service life of the drive shaft 200, the transmission component 500, and the clutch mechanism 600 is extended. Furthermore, the constraint of the protective shell 700 suppresses the deformation of the mounting base 400 under stress, thereby reducing the probability of damage to the mounting base 400 due to external pulling forces.

[0056] Furthermore, the protective shell 700 fits snugly against the mounting base 400 to better constrain the deformation of the mounting base 400.

[0057] Optionally, the protective housing 700 may be, for example, a metal housing. A metal housing has a stronger resistance to deformation, thereby further reducing the probability of damage to the mounting base 400.

[0058] Optionally, the mounting base 400 may be a housing structure, and the mounting base 400 may include a first sub-housing 420 and a second sub-housing 430, which are detachably connected and together form a receiving cavity. With this design, it is convenient to disassemble and maintain the components within the receiving cavity when the connection between the first sub-housing 420 and the second sub-housing 430 is severed.

[0059] Specifically, the protective shell 700 is provided with a clearance hole, through which the second end of the drive shaft 200 extends out of the protective shell 700.

[0060] Furthermore, the mounting base 400 and the protective housing 700 are both located within the cover 910. In this way, the cover 910 can block external impacts, thereby extending the service life of the mounting base 400 and the protective housing 700.

[0061] In other embodiments, the mounting base 400 may not have a receiving cavity, in which case the drive shaft 200, the drive element 500, and the clutch mechanism 600 may all be located outside the mounting base 400. Additionally, the door lock may not include the protective housing 700.

[0062] In a further embodiment, reference is made to... Figure 2 and Figure 5 As shown, the protective shell 700 has a first opening 710, which faces the mounting plate 100 and is covered by the mounting plate 100. The first opening 710 has a large space, which makes it easier to fit the protective shell 700 onto the mounting base 400 and to remove the protective shell 700. The first opening 710 also helps to reduce the weight of the lock body.

[0063] In other embodiments, the protective shell 700 may also omit the first opening 710. In this case, the position of the protective shell 700 corresponding to the first opening 710 may be in a blocked state.

[0064] In a further embodiment, reference is made to... Figure 2 and Figure 5 As shown, the protective shell 700 has a first shell wall 720, which is located on the side of the mounting base 400 away from the mounting plate 100. The first shell wall 720 is provided with at least two positioning posts 721 at circumferential intervals. The mounting base 400 is provided with at least two positioning holes 410 at circumferential intervals. The positioning posts 721 correspond one-to-one with the positioning holes 410. Each positioning post 721 is positioned and engaged with the corresponding positioning hole 410, and each positioning post 721 is connected to the mounting plate 100.

[0065] In this embodiment, the positioning pin 721 and the positioning hole 410 are used for positioning and engagement, which allows for relatively precise assembly of the protective shell 700 and the mounting base 400, thereby improving the assembly accuracy of the lock body. Furthermore, with the positioning pin 721 and the positioning hole 410 engaged, the positioning pin 721 is inserted into the positioning hole 410. Under their combined action, the protective shell 700 and the mounting base 400 are less likely to move relative to each other, thus improving their stability. In addition, in this embodiment, the positioning pin 721 is directly connected to the mounting plate 100, thereby connecting the protective shell 700 and the mounting base 400 as a whole to the mounting plate 100. This arrangement eliminates the need for additional connecting parts; the connection between the mounting plate 100 and the protective shell 700 and the mounting base 400 can be achieved directly with the positioning pin 721, thus simplifying the lock body structure.

[0066] Optionally, the mounting base 400 includes, for example, the first sub-housing 420 and the second sub-housing 430 mentioned above, and the positioning hole 410 includes, for example, a first hole portion 421 and a second hole portion 431. The first hole portion 421 is provided in the first sub-housing 420, and the second hole portion 431 is provided in the second sub-housing 430. The first sub-housing 420 is disposed facing the first housing wall 720, and the positioning post 721 passes through the first hole portion 421 and the second hole portion 431 in sequence and is connected to the mounting plate 100.

[0067] Optionally, the positioning post 721 may be detachably connected to the mounting plate 100 for better protection of the housing 700. More specifically, the lock body may also include, for example, a first threaded connector 440, which corresponds one-to-one with the positioning post 721. Each positioning post 721 has a threaded hole, and one end of each first threaded connector 440 passes through the mounting plate 100 and is threadedly connected to the corresponding threaded hole.

[0068] In other embodiments, the positioning post 721 may not be included, or the positioning post 721 may be included, but there is no direct connection between the positioning post 721 and the mounting plate 100.

[0069] In another embodiment, reference Figure 1 As shown, at least a portion of the edges of the mounting plate 100 are provided with reinforcing flanges 110. In other words, reinforcing flanges 110 can be provided only on a portion of the edges of the mounting plate 100, or reinforcing flanges 110 can be provided on all edges of the mounting plate 100. In this case, the reinforcing flanges 110 are arranged circumferentially around the mounting plate 100. The provision of reinforcing flanges 110 enhances the ability of the edges of the mounting plate 100 to resist deformation and improves the tensile strength of the mounting plate 100.

[0070] In other embodiments, the edge of the mounting plate 100 may not have a reinforcing flange 110.

[0071] In a further embodiment, reference is made to... Figure 1 As shown, the mounting plate 100 has a strip-shaped structure and includes at least two reinforcing flanges 110, including a first reinforcing flange 110a and a second reinforcing flange 110b. The first reinforcing flange 110a and the second reinforcing flange 110b are arranged opposite to each other in the width direction of the mounting plate 100 and both extend along the length direction of the mounting plate 100.

[0072] In actual use, the length direction of the mounting plate 100 is usually its main stress direction. By extending both the first reinforcing flange 110a and the second reinforcing flange 110b along the length direction of the mounting plate 100, the deformation resistance of the mounting plate 100 in the main stress direction can be improved, thereby extending the service life of the mounting plate 100. Furthermore, in this embodiment, the first reinforcing flange 110a and the second reinforcing flange 110b are arranged opposite each other in the width direction of the mounting plate 100. In this layout, the first reinforcing flange 110a and the second reinforcing flange 110b are symmetrically arranged on both sides of the mounting plate 100, which makes the overall stress of the mounting plate 100 more uniform, thereby further extending the service life of the mounting plate 100.

[0073] In other embodiments, the reinforcing flange 110 may also extend along the width direction of the mounting plate 100, and the number of reinforcing flanges 110 may be only one.

[0074] This application embodiment also provides a door lock, which includes a housing 910 and the lock body described above. The housing 910 is connected to the mounting plate 100 of the lock body. At least a portion of the drive shaft 200 of the lock body is disposed inside the housing 910, and at least a portion of the handle 300 of the lock body is disposed outside the housing 910 and is rotatable relative to the housing 910. Specifically, the door lock is, for example, a smart lock.

[0075] The door lock provided in this embodiment includes the lock body described above. In this door lock, the weight of the handle 300 and the external force it receives are mainly applied to the mounting plate 100. The cover 910 basically does not bear the weight of the handle 300 and the external force applied to the handle 300. As a result, the strength requirements of the cover 910 are also reduced, which makes it possible to select a variety of materials for the cover 910.

[0076] Optionally, refer to Figure 7 As shown, the housing 910 has, for example, an opening 911 through which the second end of the drive shaft 200 extends out of the housing 910. The handle 300 is located outside the housing 910 and is connected to the drive shaft 200. With this arrangement, both the second end of the drive shaft 200 and the handle 300 are located outside the housing 910, and the outside of the housing 910 has a large operating space, thereby reducing the difficulty of assembling and disassembling the handle 300.

[0077] Optionally, refer to Figure 2 As shown, the lock body also includes, for example, a second threaded connector 820. One end of the second threaded connector 820 passes through the transmission member 500 and the transmission shaft 200 mentioned above in sequence, and is threadedly connected to the handle 300 to prevent the handle 300 from separating from the transmission shaft 200. The second threaded connector 820 can rotate relative to the transmission member 500.

[0078] Specifically, the cover 910 has a second opening, and the mounting plate 100 is connected to the cover 910 and covers the second opening. The cover 910 is mounted on the door 940 through the mounting plate 100. The mounting seat 400, the protective shell 700 and the reinforcing flange 110 mentioned above are all located in the inner cavity of the cover 910.

[0079] In another embodiment, there are at least two housings 910, and the mounting plate 100 can be selectively connected to one of the housings 910. With this configuration, the mounting plate 100 can accommodate multiple different housings 910, thereby better meeting the needs of the user.

[0080] Optionally, the structural parameters of each housing 910 may be different, for example, including at least one of shape, size, material and color.

[0081] Furthermore, each cover 910 may have a different shape, and thus each cover 910 may have a different appearance. In this way, the door lock may have multiple covers 910 with different appearances, thereby meeting the diverse appearance needs of different users.

[0082] In addition, due to cost or other reasons, different users may have different requirements for the material of the cover 910. Therefore, in this embodiment, by making the material of each cover 910 different, the diverse needs of different users for the material of the cover 910 can be better met.

[0083] In addition, the lock body can be used as a universal module, and different models of door locks can be equipped with different appearance covers 910. In the actual assembly process, for example, it is only necessary to install different appearance covers 910 on the lock body to complete the assembly of different models of door locks, which improves the development and production efficiency of door locks.

[0084] In other embodiments, the number of housings 910 may also be one.

[0085] In another embodiment, the housing 910 is a non-metallic structure; in other words, the housing 910 is made of non-metallic materials. Non-metallic materials are lighter, making the overall door lock lighter and easier to carry and transport. Furthermore, non-metallic materials are less expensive, thus reducing the cost of the door lock.

[0086] Alternatively, the housing 910 may be, for example, a plastic housing.

[0087] In other embodiments, the housing 910 may also be a metal housing.

[0088] As one specific implementation method, refer to Figures 10 to 12 As shown, the lock body and housing 910 form, for example, the front lock body assembly of the door lock. In addition, the door lock also includes, for example, a rear lock body assembly 930 and a latch assembly. The front lock body assembly is located on the outside of the door body 940, and the rear lock body assembly 930 is located on the inside of the door body 940. Both the front and rear lock body assemblies 930 are connected to the door body 940. The latch assembly is mounted on the door body 940 and located between the front and rear lock body assemblies 930.
