Description

Technical Field

[0001] The present application relates to the technical field of smart locks, and specifically to the technical field of split-type aluminum alloy smart locks and processing methods thereof. Background Art

[0002] With the popularization of the concept of smart home, smart locks have gradually become the first choice for high-end residences. Consumers not only pay attention to the functionality and safety of smart locks, but also their appearance design has become one of the key factors affecting their purchasing decisions. Aluminum alloy has become an ideal material for manufacturing high-end smart lock shells due to its unique metallic texture, high strength and lightweight characteristics.

[0003] Traditional CNC machining methods, while capable of achieving a high degree of customization, are costly and inefficient. In contrast, casting offers a more cost-effective option, especially for mass production.

[0004] However, due to the high degree of fit required for smart locks, it is difficult to ensure the accuracy of the casting process. Summary of the invention

[0005] In response to the above problems, the present application proposes a split aluminum alloy smart lock and a processing method thereof, aiming to improve the shell design of the smart lock so that it can meet the high-fit smart lock requirements while using traditional casting technology.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In the first aspect, the present application proposes a split aluminum alloy smart lock, including a panel provided on the outer lock as an operation interface, and a back plate, a face cover, a base, and a door gasket are provided in sequence from the panel to the door body;

[0008] The face cover is cast from aluminum alloy and has a draft angle on the door body side, the back plate is embedded in the outside of the face cover, and the panel is attached to the back plate;

[0009] The base is cast from aluminum alloy and is provided with a draft angle toward the panel side. The door gasket includes a sealing gasket that fits the door body and a connecting gasket that fits the sealing gasket and supports the base. The sealing gasket encapsulates the connecting gasket and the periphery of the base.

[0010] In this way, the face cover and base of the outer lock of the smart lock are cast in a relatively stable depth direction, that is, they are connected to each other in the direction extending inward from the parting surface, so that their sides and connecting surfaces are relatively flat, and only simple polishing is needed to achieve the function without affecting the appearance.

[0011] Furthermore, the base is supported by a connecting pad and the outer periphery of the base is wrapped with a sealing pad, so there is no need to fine-process the inner side of the base. Similarly, the face cover is covered by a panel, and only the outer extension needs to be processed, which greatly simplifies the processing technology and cost of the aluminum alloy lock.

[0012] In some possible implementations, the inner corner of the face cover is provided with a positioning protrusion that engages with the outer corner portion of the back plate, so that the installation space of the face cover can be adjusted according to the back plate during processing, and the installation accuracy problem caused by casting is also solved.

[0013] In some possible implementations, the connection pad is provided at a lower end with an embedding bracket that can be embedded in the base and support the base, and the positioning protrusion is arranged at an upper end relative to the embedding bracket.

[0014] In some possible implementations, the face cover is provided with a plurality of mounting pads supporting the back plate on its inner periphery, and a plurality of positioning screw columns that can be embedded in the base are provided on its back. In this way, the entire face cover can maintain a stable reinforcement structure relative to the back plate, and can coordinate with the embedded bracket and be embedded in the base synchronously, so that the entire lock has a modular base design centered on the base, which is easy to achieve universalization.

[0015] In some possible implementations, the base is provided with a positioning groove at the lower end, and the surface cover is provided with an embedding block on the back that can be embedded in the positioning groove.

[0016] In some possible implementations, the embedded block is provided with a positioning screw column passing through the positioning slot.

[0017] In some possible implementations, an integrally hollow adjustment cavity is provided at the upper end of the base.

[0018] In some possible implementations, a reinforcing rib is provided on the back side of the surface cover corresponding to the adjusting cavity, and an air avoidance groove is provided in the adjusting cavity at the reinforcing rib.

[0019] On the second aspect, the present application also proposes a processing method for the split-type aluminum alloy smart lock as described above, including casting the above-mentioned face cover and base with aluminum alloy, and grinding and polishing and drilling the face cover and base, chamfering the outer side of the face cover, and then completing the assembly steps.

[0029] The following examples further illustrate the features of the present application and other related features to facilitate understanding by technicians in the same industry:

[0030] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" respectively refer to directions toward or away from the geometric center of a specific component.

[0031] Furthermore, unless otherwise clearly specified or limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this case can be understood according to specific circumstances.

[0032] Please refer to Figure 1 and Figure 2 In addition to functionality and safety, the appearance design of smart locks has also become an important reference factor. The figure shows the outer lock part, that is, the lock body displayed outside the door body, which is also the split aluminum alloy smart lock involved in this application.

[0033] Its main structure is that a panel 1 as an operation interface is arranged on the outermost side of the outer lock, that is, on the side away from the door body, and a back plate 2, a cover 3, a base 4, and a door gasket 5 are arranged in sequence from the panel 1 to the door body. The door gasket 5 includes a sealing gasket 51 that fits the door body and a connecting gasket 52 that fits the sealing gasket 51 and supports the base 4. The connecting gasket 52 can be pre-installed in the base 4, and the outer periphery of the sealing gasket 51 encapsulates the outer periphery of the connecting gasket 52 and the base 4.

[0034] On the outside, the panel 1 is the operation interface, which has password buttons, cameras, mechanical lock cover plates, etc. It is a common operation interface in the industry and is not specifically limited. In some embodiments, a handle is also provided. In this embodiment, the cover 3 as a whole is used as a handle relative to the base 4. At this time, the back panel 2 is embedded in the cover 3, and the panel 1 is attached to the back panel 3. That is, in the structure of this smart lock, the main appearance parts are the cover 3 and the base 4. Moreover, both the panel 3 and the base 4 need to be installed with functional parts, including control components, fixing components, etc.

[0035] As one of the application materials of high-end locks, aluminum alloy is used as the material for making the panel 3 and the base 4. In traditional design, considering the appearance effect and installation function, CNC processing is generally used for high-end customized products. However, it is costly and has low production efficiency, making it difficult to mass-produce to meet market demand.

[0036] In this regard, aluminum alloy casting can be used for production, but because of the need to consider its appearance and installation function, as well as its processing cost, it is necessary to optimize the structure of the overall cover 3 and the base 4 to meet the requirements of low-cost and efficient processing of the aluminum alloy smart lock.

[0037] Please refer to Figures 1 to 4 Therefore, when the panel 3 of the split aluminum alloy smart lock of the present application is cast with aluminum alloy, the draft angle is set toward the door body side, that is, the direction of assembly with the base 4. At this time, when the split surface is actually the panel 1 side, and the relatively stable depth direction, that is, the direction toward the base 4, is processed, only the panel 1 side needs to be fine-machined, and the side surface and the connection with the base 4 only need to be polished to complete the processing of the face cover 3. The side of the panel 1 itself is an appearance part, and in addition to polishing, it also needs to be precisely chamfered.

[0038] One side of the base 4 is cast from aluminum alloy and has a draft angle toward the panel 1, which is the direction of assembly with the cover 3. As described above, when the base 4 is installed with the door body, its periphery will be encapsulated by the sealing gasket 51. Therefore, its processing only requires polishing of the side surface and the joint with the cover 3. In some embodiments, the entire cover 3 and base 4 can also be subjected to surface treatments such as painting and electroplating, which are not specifically limited in this application.

[0039] In this way, the cover 3 and base 4 of the outer lock of the smart lock are cast in a relatively stable depth direction, that is, they are connected to each other in the direction extending inward from the parting surface, so that their sides and connecting surfaces are relatively flat, and only simple polishing is required to achieve the function without affecting the appearance.

[0040] Furthermore, the base 4 is supported by the connecting pad 52 and the outer periphery of the base 4 is wrapped by the sealing pad 51, and there is no need to fine-process the inner side of the base 4. Similarly, the surface cover 3 is covered by the panel 1, and only the outer extension needs to be processed, which greatly simplifies the processing technology and cost of the aluminum alloy lock.

[0041] As mentioned above, after the processing of the cover 3 and the base 4 is completed by aluminum alloy casting, they are assembled. At this time, due to the limited casting accuracy, the accuracy tolerance is considered from the design point of view, that is, the rendering effect brought by the casting accuracy is compensated by design. The first is the installation accuracy of the panel 1, which is affected by the embedding accuracy of the back panel 2.

[0042] Please refer to Figure 3 The inner corner of the face cover 3 of the split aluminum alloy smart lock of the present application, that is, the inner corner of the space where it can be embedded in the back plate 2, is provided with a positioning protrusion 31 that is locked with the outer corner part of the back plate 2. Through the positioning protrusion 31, the installation space of the face cover 3 is adjusted according to the back plate 2 during processing, because it is an independent setting that does not affect the appearance, and the installation position can be controlled, solving the installation accuracy problem.

[0043] Further, please combine Figure 2 and Figure 3 The connecting pad 52 is provided with an embedded bracket 521 at the lower end which can be embedded into the base 4 and support the base 4. At this time, the base 4 is in a relatively fixed state, so the positioning protrusion 31 of the face cover 3 is arranged at the upper end relative to the embedded bracket 521, so as to facilitate the adjustment of the installation of the back panel 2.

[0044] Please refer to Figure 3 and Figure 5The inner periphery of the face cover 3 is provided with a plurality of mounting pads 32 for supporting the back plate 2, and the mounting pads 32 are provided with screw holes for fixing, so that the entire face cover 3 can maintain a stable reinforcement structure relative to the back plate 2. At the same time, the back of the face cover 3 is provided with a plurality of positioning screw columns 33 that can be embedded in the base 4. The positioning screw columns 33 and the embedded brackets 521 are coordinated on both sides of the base 4 and are synchronously embedded in the base 4, so that the entire lock is designed as a modular base with the base 4 as the center, which is convenient for universalization.

[0045] Please refer to Figures 5 to 7 as well as Fig. 9 In addition to the positioning screw column 33 on the cover 3 and the base 4, the present application also adopts a positioning design. A positioning groove 41 is provided at the lower end of the base 4, which is recessed toward one side of the door body. Correspondingly, an embedding block 34 that can be embedded in the positioning groove 41 is provided on the back of the cover 3. Through the embedding positioning of the block, the installation stability is improved while avoiding the error caused by the deformation or misalignment of the positioning screw column 33. Furthermore, the embedding block 34 is provided with a positioning screw column 33 that passes through the positioning groove 41. (At this time, the function of the positioning screw column 33 is the same and no additional marking is made.)

[0046] As mentioned above, the positioning of the split aluminum alloy smart lock in this application is mainly completed by the lower end. And the control of its fault tolerance needs to be completed by the upper end, please refer to Figures 4 to 8 An integrally hollow adjusting cavity 42 is provided at the upper end of the base 4. In addition to being a weight-reducing hole, the adjusting cavity 42 has a thin wall that allows for fine-tuning.

[0047] Correspondingly, a reinforcing rib 35 is provided on the back side of the cover 3 corresponding to the adjusting cavity 42 to reinforce the overall strength. Meanwhile, an avoidance groove 43 is provided in the adjusting cavity 42 at the reinforcing rib 35 to avoid interference from the reinforcing rib 35 during installation.

[0048] In this way, the split aluminum alloy smart lock of the present application can be processed by casting the above-mentioned cover 3 and base 4 with aluminum alloy, and then grinding and polishing the cover 3 and base 4, drilling holes, chamfering the outer side of the panel 3, and assembling. At this time, the drilling holes mainly refer to the necessary installation holes.

[0049] As mentioned above, this application protects a split-type aluminum alloy smart lock and a processing method thereof. All technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
