[0038] Embodiment 1:

[0039] See also Figure 1-Figure 7 This embodiment provides a smart lock, including a housing, a keypad 7, a handle assembly 5 and a tempered glass plate 8. The tempered glass plate 8 is attached to the front outer wall of the housing to protect the housing.

[0040] The shell includes a non-metallic outer cover 1, a back cover 2 and a metal cover 3. In this embodiment, the non-metallic outer cover 1 encloses a cavity, so that the non-metallic outer cover 1 can be covered on the metal cover 3, thereby forming a front cover with a double-layer structure. There will be contact between the outer wall of the metal cover 3 and the inner wall of the non-metallic outer cover 1, so that the metal cover 3 has a supporting effect on the non-metallic outer cover 1. Common contact methods include fitting, for example, the outer wall of the metal cover 3 is completely fitted or partially fitted with the inner wall of the non-metallic outer cover 1. Correspondingly, a certain gap is also allowed between the outer wall of the metal cover 3 and the inner wall of the non-metallic outer cover 1. The gap can be actively reserved for design reasons, or it can be generated based on assembly process or assembly error. It is easy to understand that if the above-mentioned gap exists between the inner wall of the non-metallic outer cover 1 and the outer wall of the metal cover 3 in this embodiment, the size of the above-mentioned gap is usually small.

[0041] The non-metallic outer cover 1 can be further fixed to the metal cover 3 on the basis of covering the metal cover 3. For example, the metal cover 3 can be adhered to the non-metallic outer cover 1, or screwed to the non-metallic outer cover 1, or buckled to the non-metallic outer cover 1, so that the entire front cover can be subsequently assembled as a whole.

[0042] The rear cover 2 covers the rear opening of the non-metallic outer cover 1 , so that the rear cover 2 and the non-metallic outer cover 1 enclose a mounting cavity 4 . Correspondingly, the metal cover 3 is also located in the mounting cavity 4 .

[0043] See also Figure 4-Figure 6 In this embodiment, a first avoidance hole 111 is opened on the non-metallic outer cover 1, and a second avoidance hole 311 is opened on the metal cover 3. The first avoidance hole 111 and the second avoidance hole 311 are connected. The handle assembly 5 passes through the first avoidance hole 111 and the second avoidance hole 311, so that a part of the handle assembly 5 is located in the installation cavity 4, and the handle assembly 5 is also allowed to be rotatably set on the metal cover 3.

[0044] It can be understood that the back cover 2 needs to be connected to the door on which the smart lock is to be installed. Therefore, the actual exposed part of the shell during normal use of the smart lock is the front side wall and the peripheral side wall of the shell, which corresponds to the outer wall of the non-metallic outer cover 1 in this embodiment.

[0045] The non-metallic outer cover 1 is made of non-metallic materials, and common non-metallic materials include carbon fiber, PC and ABS, etc. Such non-metallic materials can be used to prepare a non-metallic outer cover 1 with a smooth surface without surface treatment. The metal cover 3 is made of common metal materials, such as titanium alloy, aluminum, iron, stainless steel, copper, etc. In this embodiment, the metal cover 3 is shielded by the non-metallic outer cover 1 with the metal cover 3, thereby avoiding the exposure of the metal cover 3. By replacing the metal cover 3 with the non-metallic outer cover 1 as the exposed part of the shell, there is no need to perform surface treatment on the metal cover 3. In addition, the metal cover 3 can support and reinforce the non-metallic outer cover 1 on the inside of the non-metallic outer cover 1, reduce the deformation of the non-metallic outer cover 1, and improve the impact resistance of the non-metallic outer cover 1, so that the shell can meet the safety and hardness requirements. It can be seen that the shell of the smart lock in this embodiment avoids the surface treatment process on the basis of meeting the hardness and outer surface requirements by cooperating with the non-metallic outer cover 1 and the metal cover 3, thereby reducing the production cycle of the smart lock.

[0046] In this embodiment, the non-metallic outer cover 1 includes a first substrate 11 and a first surrounding edge 12 fixed at the edge of the first substrate 11, and the first avoidance hole 111 is located on the first substrate 11. Matchingly, the metal cover 3 includes a second substrate 31 and a second surrounding edge 32 fixed at the edge of the second substrate 31, and the second avoidance hole 311 is located on the second substrate 31.

[0047] In order to improve the support strength of the metal cover 3 on the non-metallic outer cover 1, the first substrate 11 can be at least partially attached to the second substrate 31, and / or the first surrounding edge 12 can be at least partially attached to the second surrounding edge 32. The shape of the first surrounding edge 12 matches the second surrounding edge 32, so that the non-metallic outer cover 1 can be covered on the metal cover 3.

[0048] In some other embodiments, a certain deformation gap is reserved between the first surrounding edge 12 and the second surrounding edge 32, and the two are not completely tightly fitted. The reason is that the metal cover 3 and the non-metallic outer cover 1 are not made of the same material, so the deformation amount is different when heated, and the deformation amount of the metal cover 3 is larger after heating. The above deformation gap provides the metal cover 3 with additional space for thermal deformation, so that the first surrounding edge 12 avoids the second surrounding edge 32 during the heating process of the shell, avoiding excessive compression of the non-metallic outer cover 1 by the metal cover 3 after being deformed by heat, causing unnecessary damage to the non-metallic outer cover 1.

[0049] In this embodiment, the first substrate 11 and the second substrate 31 are both substantially rectangular, there are four first surrounding edges 12 and they are respectively arranged on the four sides of the first substrate 11, and there are four second surrounding edges 32 and they are respectively arranged on the four sides of the second substrate 31, so that the non-metallic outer cover 1 and the metal cover 3 are both substantially rectangular.

[0050] In this embodiment, a plurality of buckles 122 are provided on the edge of the first surrounding edge 12 away from the first substrate 11 , and the buckles 122 buckle the edge of the second surrounding edge 32 away from the second substrate 31 , thereby fixing the metal cover 3 in the non-metallic outer cover 1 .

[0051] In this embodiment, the edge of the second surrounding edge 32 away from the second substrate 31 abuts against the back cover 2. In some other embodiments, if the metal cover 3 is not fixed to the non-metallic outer cover 1, after the back cover 2 and the non-metallic outer cover 1 are fixed, the back cover 2 can press the second substrate 31 onto the first substrate 11 through the second surrounding edge 32 to ensure the supporting and reinforcing effect of the second substrate 31 on the first substrate 11.

[0052] In order to improve the sealing effect between the non-metallic outer cover 1 and the back cover 2, a positioning rib 121 is provided on the edge of the first surrounding edge 12 away from the first substrate 11, and a slot 21 is provided on the back cover 2. After the positioning rib 121 is inserted into the slot 21, the edge of the first surrounding edge 12 away from the first substrate 11 can abut against the back cover 2.

[0053] The material of the back cover 2 in this embodiment is also non-metallic. The back cover 2 and the non-metallic outer cover 1 can be made of the same non-metallic material or different non-metallic materials. The smart lock in this embodiment also includes a metal plate 6, which is attached to the back cover 2. The metal plate 6 supports and reinforces the back cover 2, further improving the safety of the shell.

[0054] Furthermore, an avoidance notch 321 is provided at the edge of the second surrounding edge 32 facing away from the second substrate 31, and part of the edge of the metal plate 6 is accommodated in the avoidance notch 321. On the one hand, the second surrounding edge 32 can avoid the metal plate 6 through the avoidance notch 321, and on the other hand, the edge of the avoidance notch 321 can also press the metal plate 6 onto the back cover 2, thereby having a positioning effect on the metal plate 6.

[0055] In this embodiment, a third avoidance hole 112 is further provided on the first substrate 11, the keypad 7 is mounted at the third avoidance hole 112, and the tempered glass plate 8 covers the third avoidance hole 112, and the keypad 7 is operated by pressing a corresponding position on the tempered glass plate 8. Of course, the tempered glass plate 8 is provided with corresponding holes to avoid the handle assembly 5.

[0056] Embodiment 2:

[0057] See also Figure 8-Figure 11 The present embodiment provides a smart lock, including a housing, a tempered glass plate 8 and a handle assembly. In the present embodiment, the housing includes a non-metal rear cover 10 and a metal cover 3.

[0058] The metal cover 3 and the non-metallic rear cover 10 are connected in a plug-in manner, so that the non-metallic rear cover 10 and the metal cover 3 enclose a cavity, wherein the metal cover 3 is provided with a second avoidance hole 311, the second avoidance hole 311 is connected to the above-mentioned cavity, and the handle assembly is rotatably arranged at the second avoidance hole 311. The metal cover 3 is connected to the non-metallic rear cover 10 in a manner that at least part of the metal cover 3 is accommodated inside the non-metallic rear cover 10, and at least part of the metal cover 3 is shielded by the non-metallic rear cover 10, thereby reducing the direct exposure of the metal cover 3 and reducing the surface treatment requirements of the metal cover 3. On the other hand, the part of the metal cover 3 located inside the non-metallic rear cover 10 can be used to reinforce and support the non-metallic rear cover 10, thereby improving the strength of the non-metallic rear cover 10.

[0059] The non-metal rear cover 10 of this embodiment includes a third substrate 101 and a third surrounding edge 102 fixed at the edge of the third substrate 101. The third substrate 101 and the third surrounding edge 102 are arranged to form a receiving groove 9, and the receiving groove 9 can be used to accommodate the metal cover 3. In this embodiment, the metal cover 3 also includes a second substrate 31 and a second surrounding edge 32 fixed at the edge of the second substrate 31. The second surrounding edge 32 can improve the strength of the metal cover 3. The second substrate 31 and the third substrate 101 are substantially parallel and spaced apart to ensure that the metal cover 3 and the non-metal rear cover 10 can be arranged to form the aforementioned cavity. The second surrounding edge 32 is at least partially attached to the third surrounding edge 102, so that the third surrounding edge 102 can shield the second surrounding edge 32 to prevent the second surrounding edge 32 from being exposed, and the second surrounding edge 32 also reinforces and supports the third surrounding edge 102.

[0060] Therefore, the actual exposed portion of the metal cover 3 in this embodiment is the third substrate 101 . Therefore, in this embodiment, the tempered glass plate 8 is disposed on a side of the second substrate 31 away from the third substrate 101 to avoid direct exposure of the second substrate 31 .

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
