A lock case structure of an intelligent lock

Abstract

This utility model provides a lock shell structure for a smart lock, belonging to the field of door lock technology. It solves the problem of poor strength and aesthetics caused by the inadequate molding method of existing smart lock shells. This lock shell structure includes an interconnected front panel and a rear panel. The front panel includes a front cover plate and a front panel middle frame with matching edges. The rear panel includes a rear cover plate and a rear panel middle frame with matching edges. Both the front and rear panel middle frames are obtained by expanding a circular annular tube blank to form a rectangular annular tube blank with rounded corners, followed by cutting. The front cover plate and the front panel middle frame are welded together, with the welding position located on the inner ring portion of the front panel middle frame. Similarly, the rear cover plate and the rear panel middle frame are welded together, with the welding position located on the inner ring portion of the rear panel middle frame. Compared with existing technologies, this lock shell structure forms the middle frame in a single molding process, resulting in higher structural strength and a more aesthetically pleasing appearance.

Description

Technical Field

[0001] This utility model belongs to the field of door lock technology and relates to a lock shell structure for a smart lock. Background Technology

[0002] Because the outer lock shell of a smart lock has multiple surfaces, it usually requires multiple plates to be spliced ​​together by connectors or connecting structures. Due to the multiple connections involved in the manufacturing process, the process is complicated and inefficient. Moreover, the finished lock shell has many gaps and is not aesthetically pleasing. Summary of the Invention

[0003] The purpose of this utility model is to address the problem of poor strength and aesthetics caused by the poor molding method of the outer lock shell of existing smart locks, and to propose a lock shell structure for smart locks.

[0004] The objective of this utility model can be achieved through the following technical solutions: A lock shell structure for a smart lock, characterized in that it includes a front panel and a rear panel connected to each other. The front panel includes a front cover plate and a front panel middle frame with matching edges, and the rear panel includes a rear cover plate and a rear panel middle frame with matching edges. Both the front panel middle frame and the rear panel middle frame are obtained by expanding a circular annular tube blank to form a rectangular annular tube blank with rounded corners, and then cutting it. The front cover plate and the front panel middle frame are formed by welding, and the welding position is in the inner ring portion of the front panel middle frame. The rear cover plate and the rear panel middle frame are formed by welding, and the welding position is in the inner ring portion of the rear panel middle frame.

[0005] In the lock shell structure of the aforementioned smart lock, multiple mating holes and connecting holes are respectively provided at the alignment positions of the front cover plate and the rear cover plate. After the front panel and the rear panel are assembled and aligned, the mating holes and connecting holes correspond one-to-one. The connecting holes are threaded, and the mating holes and connecting holes are connected by studs.

[0006] In the lock shell structure of the aforementioned smart lock, the connecting hole is a stepped hole that connects a large hole and a small hole. The stud size is the same as that of the small hole, and the tail end of the stud is provided with a disc with the same size as that of the large hole. The disc is completely embedded in the large hole.

[0007] In the lock shell structure of the aforementioned smart lock, the rectangular annular tube blank is cut using laser cutting.

[0008] Compared with existing technologies, this lock housing structure forms the middle frame through a one-piece molding method, resulting in higher structural strength and a more aesthetically pleasing appearance. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the first structure of the lock case after the front and rear panels have been disassembled; Figure 2This is a schematic diagram of the second structure of the lock case after the front and rear panels have been disassembled; Figure 3 This is a schematic diagram of the third structure of the lock case after the front and rear panels have been disassembled; In the diagram, 1 is the front cover plate; 2 is the front panel frame; 3 is the rear cover plate; 4 is the rear panel frame; 5 is the mating hole; 6 is the connecting hole; and 7 is the stud. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown in Figure 3, the lock shell structure of this smart lock includes a front panel and a rear panel that are connected to each other. The front panel includes a front cover plate 1 and a front panel middle frame 2 with matching edges. The rear panel includes a rear cover plate 3 and a rear panel middle frame 4 with matching edges. The front panel middle frame and the rear panel middle frame are both obtained by expanding a circular annular tube blank to form a rectangular annular tube blank with rounded corners, and then cutting it. The front cover plate and the front panel middle frame are formed by welding, and the welding position is in the inner ring part of the front panel middle frame. The rear cover plate and the rear panel middle frame are formed by welding, and the welding position is in the inner ring part of the rear panel middle frame.

[0012] The front and rear mid-frames are obtained by expansion and cutting, so the entire front and rear mid-frames are integrally formed, eliminating the need for multiple panels to be spliced ​​together, resulting in higher strength, fewer processes, and a more aesthetically pleasing appearance.

[0013] The front cover and front panel frame, as well as the rear cover and rear panel frame, are all welded inside the frame. The weld points are not exposed on the outside, so there is no need for grinding, and grinding will not reduce the smoothness and aesthetics.

[0014] Multiple mating holes 5 and connecting holes 6 are provided at the alignment positions of the front cover and the rear cover. After the front panel and the rear panel are assembled and aligned, the mating holes and connecting holes correspond one-to-one. The connecting holes are threaded, and the mating holes and connecting holes are connected by studs 7.

[0015] The connecting hole is a stepped hole that connects the large hole and the small hole. The stud size is the same as the small hole. The tail end of the stud is provided with a disc with the same size as the large hole. The disc is completely embedded in the large hole.

[0016] When the stud is used to assemble the front and rear cover plates, the insert at the tail of the stud is fully embedded in the large hole and will not protrude outwards, so there will be no interference during the installation of the smart lock.

[0017] Laser cutting is used for cutting rectangular annular tube blanks. This reduces the number of processes and increases utilization.

[0018] It should be understood that in the claims and description of this utility model, all instances of "comprising..." should be understood as having an open meaning, that is, their meaning is equivalent to "containing at least...", and should not be understood as having a closed meaning, that is, their meaning should not be understood as "containing only...".

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
