Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, and in particular to a C-shaped handle for switching between left and right sides installed on the main body of a smart door lock. Background Technology

[0002] With the rapid development of the smart home industry, smart door locks, as core devices for home security and convenient access, are facing increasing demands for functional integration and adaptability. Modern smart door locks not only integrate diverse intelligent interactive functions such as fingerprint recognition, touch operation, and video monitoring, but also need to consider installation scenarios for different door types and meet users' comprehensive demands for practicality, security, and aesthetics. However, in practical applications, the door lock handle, as a directly operated component, directly affects the user experience and the product's universal compatibility, making it a key area for optimization during the smart door lock development process.

[0003] Currently, most mainstream smart door locks on the market use a fixed handle design, with the installation orientation and position determined during the manufacturing stage. This fixed design has significant limitations: Firstly, for doors with left-opening and right-opening directions, corresponding handle components need to be manufactured separately, increasing production management costs and inventory pressure for enterprises. It also causes inconvenience for users in purchasing and installation. In particular, when doors with left-opening and right-opening directions are opened or closed, the operator's hand is easily rubbed against the wall, causing the hand to be pinched. If the wrong model is matched, it needs to be replaced, reducing installation efficiency. Secondly, fixed handles cannot be adjusted according to actual usage needs, making it difficult to switch between hiding and exposing the emergency keyhole. This results in the emergency keyhole being exposed for a long time, which can easily cause operational malfunctions due to accidental touches and may also become an entry point for malicious damage, affecting the security performance and overall appearance of the door lock.

[0004] Therefore, this utility model proposes a C-shaped handle for left and right switching installed on the main body of a smart door lock to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a left-right switching C-shaped handle installed on the main body of a smart door lock, which includes a door lock body, the door lock body including a main structure, the main structure having a square groove on its surface, and a handle base plate being fitted at the square groove of the main structure, the handle base plate having an emergency key unlocking hole on its surface, the emergency key unlocking hole penetrating the main structure, the main structure being fitted with a C-shaped front lock handle through the handle base plate, the C-shaped front lock handle including a C-shaped handle plate body and a locking member installed on the C-shaped handle plate body facing the handle base plate, the locking member penetrating the handle base plate and extending into the inner cavity of the main structure;

[0007] The main structure has a waist-shaped guide groove on its surface and a limiting guide lock groove on its bottom plate. The waist-shaped guide groove and the limiting guide lock groove partially overlap to form a locking groove structure that locks and guides the C-shaped front lock handle.

[0008] As a preferred embodiment of the C-shaped handle for left and right switching installed on the main body of the smart door lock according to the present invention, the main body of the door lock includes a front lock front sheet metal and a front lock main body enclosure plate that bends and extends along the outer periphery of the front lock front sheet metal. A front lock rear iron plate is fitted on the side of the front lock main body enclosure plate that is away from the front lock front sheet metal, and a front lock glass is attached to the side of the front lock front sheet metal that is away from the front lock rear iron plate.

[0009] As a preferred embodiment of the C-shaped handle for left and right switching installed on the main body of the smart door lock according to the present invention, the number of locking components is two sets, and the two sets of locking components are installed on the surface of the C-shaped handle plate body. The locking component includes a guide plate and a raised strip plate. The guide plate and the C-shaped handle plate body are arranged parallel to the height direction of the front lock sheet metal. The raised strip plate extends symmetrically on both sides along the width direction of the guide plate, away from the edge of the guide plate body.

[0010] As a preferred embodiment of the left-right switching C-shaped handle installed on the main body of the smart door lock according to this utility model, the limiting guide lock groove includes a narrowing groove and an enlarged groove that are connected. The center line of the narrowing groove and the enlarged groove is parallel to the height direction of the front lock sheet metal. The groove diameter of the narrowing groove is consistent with the thickness of the guide plate. The groove diameter of the enlarged groove is equal to the end thickness of the locking member away from the C-shaped handle plate body.

[0011] As a preferred embodiment of the C-shaped handle for left and right switching installed on the main body of the smart door lock according to the present invention, wherein: the groove diameter width of the waist-shaped guide groove is consistent with the groove diameter width of the reduced portion of the limiting guide lock groove, and the groove diameter length of the waist-shaped guide groove is consistent with the groove diameter length of the reduced portion of the limiting guide lock groove.

[0012] As a preferred embodiment of the C-shaped handle for left and right switching installed on the main body of the smart door lock as described in this utility model, the distance between the C-shaped handle plate body and the convex strip plate is equal to the thickness of the handle base plate.

[0013] The beneficial effects of this utility model are as follows: Based on the symmetrical structural design of the locking component, this application achieves flexible interchangeability of the left and right positions of the C-shaped front lock handle. The handle opening direction can be adjusted according to the left or right opening direction of the door, ensuring that the C-shaped front lock handle opening is always aligned with the side where the operator can easily apply force.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a left-right switching C-shaped handle installed on the main body of a smart door lock: it includes a door lock body, the door lock body includes a main structure, a square groove 0012 is opened on the surface of the main structure, and a handle base plate 005 is installed at the square groove 0012 of the main structure. An emergency key unlocking hole 0051 is opened on the surface of the handle base plate 005. The emergency key unlocking hole 0051 is equipped with a mechanical emergency key for opening the smart door lock. The emergency key unlocking hole 0051 passes through the main structure. A C-shaped front lock handle 006 is installed on the main structure through the handle base plate 005. The C-shaped front lock handle 006 includes a C-shaped handle plate body 0061 and a locking member 0062 installed on the C-shaped handle plate body 0061 facing the handle base plate 005. The locking member 0062 passes through the handle base plate 005 and extends into the inner cavity of the main structure.

[0028] The main structure has a waist-shaped guide groove 0011 on its surface and a limiting guide lock groove 0052 on its bottom plate 005. The waist-shaped guide groove 0011 and the limiting guide lock groove 0052 partially overlap to form a locking groove structure that locks and guides the C-shaped front lock handle 006.

[0029] Reference Figures 1-3 As shown, the door lock body includes a front lock sheet metal 001 and a front lock body enclosure 002 that bends and extends along the outer periphery of the front lock sheet metal 001. The front lock sheet metal 001 and the front lock body enclosure 002 form an integral front lock body frame. The handle base plate 005 and the front lock sheet metal 001 can be an integral structure. A front lock rear iron plate 003 is fitted on the side of the front lock body enclosure 002 facing away from the front lock sheet metal 001. The front lock sheet metal 001, the front lock body enclosure 002, and the front lock rear iron plate 003 form an internal hollow installation space. The front lock sheet metal 001 faces away from the front lock... The front lock glass 004 is attached to one side of the rear iron plate 003. The square groove 0012 passes through the front lock glass 004 and is located in its lower area. The upper part of the front lock glass 004 is provided with a touch button area for user operation, a fingerprint recognition module for identity verification, and a high-definition camera for monitoring the situation outside the door. Each component is electrically connected to the control module of the door lock body through internal wiring to form a complete intelligent interaction and security system. The internal wiring and control module are installed in the installation space enclosed by the front lock sheet metal 001, the front lock body enclosure 002, and the front lock rear iron plate 003.

[0030] Furthermore, a square groove 0012 is formed on the surface of the front lock glass 004.

[0031] Reference Figure 5 As shown, there are two sets of locking components 0062. The two sets of locking components 0062 are installed on the surface of the C-shaped handlebar body 0061. The locking component 0062 includes a guide plate 00621 and a raised strip plate 00622. The guide plate 00621 and the C-shaped handlebar body 0061 are arranged parallel to the height direction of the front lock sheet metal 001. The raised strip plate 00622 extends symmetrically on both sides of the guide plate 00621 along the width direction of the guide plate 00621, away from the edge of the C-shaped handlebar body 0061, so that the front end of the locking component 0062 forms an enlarged portion larger than the guide plate 00621. The raised strip plates 00622 of the two sets of locking components 0062 are set on the opposite side of the guide plate 00621.

[0032] Furthermore, the locking component 0062 is a symmetrical structure. The convex strip extends symmetrically on both sides of the guide plate 00621, away from one end edge of the C-shaped handle body. This, combined with the parallel arrangement of the guide plate 00621 and the C-shaped handle body along the height direction of the front lock sheet metal, creates a symmetrical structure with the center line of the guide plate 00621 as the axis of symmetry. This allows the C-shaped front lock handle to have multiple installation adaptability capabilities: whether left-hand or right-hand installation is required, there is no need to replace the dedicated locking component 0062. Simply by adjusting the installation orientation of the C-shaped handle body, the symmetrical locking component 0062 can achieve precise alignment and assembly with the defined guide lock groove 0052 of the handle base plate 005. Then, through the fixed connection between the handle base plate 005 and the main structure, the C-shaped front lock handle can be installed on the main structure to the left or right, perfectly matching the left-opening and right-opening requirements of different door types, further enhancing the product's adaptability and versatility.

[0033] Furthermore, the limiting guide lock groove 0052 includes a connected reducing groove 00521 and an expanding groove 00522. The center line of the reducing groove 00521 and the expanding groove 00522 is parallel to the height direction of the front lock sheet metal 001. The groove diameter of the reducing groove 00521 is consistent with the thickness of the guide plate 00621. The groove diameter of the expanding groove 00522 is consistent with the end thickness of the locking member 0062 away from the C-shaped handle plate body 0061.

[0034] Reference Figure 4 As shown, the groove width of the waist-shaped guide groove 0011 is the same as the groove width of the reduced portion groove 00521 of the limiting guide lock groove 0052, and the groove length of the waist-shaped guide groove 0011 is the same as the groove length of the reduced portion groove 00521 of the limiting guide lock groove 0052.

[0035] Reference Figure 4 As shown, the distance between the C-shaped handle body 0061 and the raised strip 00622 is equal to the thickness of the handle base plate 005.

[0036] Furthermore, the handle base plate 005 is bolted to the square groove 0012 area of ​​the front lock sheet metal 001, forming a tight and fixed connection between the handle base plate 005 and the front lock sheet metal 001. The C-shaped handle plate body 0061 is in surface contact with the outer surface of the handle base plate 005, and its back surface is precision-polished to reduce frictional resistance during movement. In the assembled state, the C-shaped handle plate body 0061 can move directionally along the surface of the handle base plate 005. The movement trajectory is strictly limited by the guiding effect of the waist-shaped guide groove 0011, so that the C-shaped front lock handle 0011 moves along the height direction of the front lock sheet metal 001.

[0037] Furthermore, the locking groove structure is formed by the partial overlap of the waist-shaped guide groove 0011 opened on the surface of the front lock sheet metal 001 and the limiting guide lock groove 0052 opened on the surface of the handle base plate 005. Since the handle base plate 005 is fixed to the front lock sheet metal 001 by bolts, the waist-shaped guide groove 0011 and the reduced groove 00521 of the limiting guide lock groove 0052 are completely aligned and overlapped, while the enlarged groove 00522 of the limiting guide lock groove 0052 is covered by the handle base plate 005, so that the locking member 0062 cannot be separated from the handle base plate 005 covering the surface of the front lock sheet metal 001, forming a composite groove structure with overlapping guide sections and independent locking sections.

[0038] Example 2

[0039] Reference Figure 5 and Figure 7 As shown, the second embodiment of the present invention is based on the previous embodiment. The difference is that the C-shaped handle body 0061 in embodiment 1 is configured as a C-shaped or U-shaped structure, and its C-shaped handle body 0061 can also be configured as an I-shaped or Z-shaped structure.

[0040] Working principle: During assembly, first align the locking member 0062 of the C-shaped front lock handle 006 with the limiting guide lock groove 0052 of the handle base plate 005, so that the enlarged portion of the locking member 0062 passes through the enlarged portion groove 00522. The width of the enlarged portion groove 00522 matches the thickness of the enlarged portion, so that the locking member 0062 passes through the handle base plate 005. The distance between the C-shaped handle plate body 0061 and the raised strip plate 00622 is equal to the thickness of the handle base plate 005. During movement, the enlarged portion of the locking member 0062 tightly engages with the back of the handle base plate 005.

[0041] After the enlarged portion of the locking member 0062 passes through the enlarged portion groove 00522, the locking member 0062 moves downward along the height of the front lock sheet metal 001, causing the guide plate 00621 of the locking member 0062 to correspondingly enter the reduced portion groove 00521 of the limiting guide lock groove 0052. Since the width of the reduced portion groove 00521 is the same as the thickness of the guide plate 00621, the guide plate 00621 and the reduced portion groove 00521 form a tight fit at this time.

[0042] Insert the protruding strip 00622 of the locking component 0062 into the waist-shaped guide groove 0011 along the position of the waist-shaped guide groove 0011 of the front lock sheet metal 001, and fasten the handle base plate 005 to the square groove 0012 area of ​​the front lock sheet metal 001 with bolts. At this time, the waist-shaped guide groove 0011 on the surface of the front lock sheet metal 001 is completely aligned and overlapped with the reduced groove 00521 of the handle base plate 005, forming a guide channel that runs through both. The enlarged groove 00522 of the handle base plate 005 is completely covered by the surface of the front lock sheet metal 001, forming a closed state. The enlarged part of the locking part 0062 is always blocked by the front lock sheet metal 001 during the movement and cannot enter the enlarged groove 00522 again, so as to restrict the C-shaped front lock handle 006 from leaving the current guide trajectory and from being disassembled in reverse through the enlarged groove 00522, so as to form a stable mechanical lock. After the assembly is completed, the C-shaped handle plate body 0061 can move directionally along the surface of the handle base plate 005 to achieve the shielding and opening of the emergency key unlocking hole 0051.

[0043] This application achieves the interchangeability of the left and right positions of the C-shaped front lock handle 006 through structural design. The opening direction of the C-shaped front lock handle 006 can be flexibly adjusted according to the left or right opening direction of the door, so that the opening always protrudes in the direction that is convenient for the operator to apply force. This avoids the C-shaped front lock handle 006 from causing the hand to be pinched, greatly improving the comfort and convenience of opening the door. There is no need to design or purchase special handles for different door orientations, thus reducing the product adaptation threshold. Meanwhile, the C-shaped front lock handle can move up and down along the height direction. When it is necessary to use the mechanical emergency key to unlock, moving the C-shaped front lock handle 006 will expose the emergency key unlocking hole 0051. In daily use, the C-shaped front lock handle 006 can be moved to cover the emergency key unlocking hole 0051, which not only avoids the emergency lock being accidentally touched or maliciously operated due to being exposed, but also maintains the integrity and aesthetics of the door lock surface, achieving a balance between functionality and security. Secondly, the structure of the door lock body of this application is simplified, with low cost and high reliability. The overall mechanical structure of the slot and plate combination realizes both portable door opening and security functions, without the need for complex transmission components or electronic control modules, which not only simplifies the production and processing process, but also reduces material and manufacturing costs.

[0044] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
