[0040] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0041] In the related technology, whether it is a real mortise lock or a fake lock core, a keyhole needs to be reserved on the front panel of the smart lock, and a sliding cover mechanism needs to be set down to cover the keyhole. The only difference is the position of the keyhole. The reserved keyhole will increase the length of the door lock panel, and the sliding cover mechanism will increase the manufacturing cost. It is also easy to be damaged by violence and has low security.

[0042] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0043] According to an embodiment of the present utility model, in a first aspect, a lock 100 with a hidden keyhole is provided, such as Figure 1 As shown, it includes a panel assembly 101 and a handle assembly 102. The panel assembly 101 is suitable for being installed on a door, and the door may be an entrance door, an opening and closing door of a safe, or other doors that require a lock. A keyhole portion 1011 is provided on the panel assembly 101, and the direction in which the key 200 is inserted into the keyhole portion 1011 is the insertion direction. The handle assembly 102 is screwed onto the panel assembly 101 through a bracket or other structure. The handle assembly 102 and the keyhole portion 1011 are spaced apart, that is, there is a certain distance between the two. The handle assembly 102 can at least block a portion of the keyhole portion 1011 along the insertion direction, that is, the handle assembly 102 can block a portion or completely block the keyhole portion 1011. When it is completely blocked, the probability of the keyhole portion 1011 being difficult to be discovered can be increased, thereby further improving safety and aesthetics.

[0044] In this embodiment, the handle assembly 102 is fixedly set on the panel assembly 101 and can block at least a part of the keyhole portion 1011 along the plugging direction of the keyhole portion 1011, so that the handle assembly 102 and the keyhole portion 1011 are overlapped, thereby shortening the length of the panel assembly 101, and the handle assembly 102 can block the keyhole portion 1011, and there is no need to set a blocking component to cover the keyhole portion 1011, which not only reduces the cost, but also makes it inconvenient to find the keyhole portion 1011, thereby improving safety; at the same time, the fixed handle assembly 102 can limit the operating space for unlocking, making it inconvenient to perform violent disassembly, thereby further improving safety; it is particularly suitable for smart locks, such as smart locks with fingerprint unlocking and / or face unlocking, which are not often unlocked with the key 200, and both unlocking convenience and safety can be taken into account.

[0045] In one embodiment, Figures 1 to 3 As shown, the key 200 includes a connected hand-held part 201 and an unlocking part 202. During the unlocking rotation process of the key 200, the assembled length of the hand-held part 201 and the unlocking part 202 along the plugging direction is the unlocking length, and the distance from the keyhole part 1011 to the handle assembly 102 along the plugging direction is less than the unlocking length.
