[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] See Figure 1 and Figure 2 This utility model provides a lock body structure for a smart door lock, including a lock body 1, a lock cylinder 2, and a lock body protective block 3. The lock body 1 is provided with a clutch 11, and the clutch 11 is provided with a slot 111 adapted to one end of the lock body protective block 3. The outer shell of the lock body 1 is provided with a through hole 112 adapted to the rotation space of one end of the lock body protective block 3. One end of the lock body protective block 3 passes through the through hole 112 and is inserted into the slot 111. The other end of the lock body protective block 3 is connected to the insertion handle 21 of the lock cylinder 2. The diameter of the other end of the lock body protective block 3 is larger than the diameter of the through hole 112.

[0023] In this embodiment, the lock cylinder 2 is a structure for inserting a mechanical key, and the lock cylinder 2 can be fixedly connected to the housing of the smart lock; the clutch 11 is a structure for driving the smart lock to unlock, and the driving component of the clutch 11 is housed inside the lock body 1; the diameter of the other end of the lock body protective block 3 is larger than the diameter of the through hole 112, which enables the lock body protective block 3 to limit the insertion handle. When the mechanical key is inserted into the lock cylinder 2 and rotated to unlock, the insertion handle 21 rotates accordingly, and drives the lock body protective block 3 to rotate, which in turn drives the clutch 11 to unlock; when the lock cylinder 2 is subjected to external force (such as when the lock cylinder is damaged by a criminal) and is pushed inward, causing the insertion handle 21 to be forced to push into the clutch 11, the insertion handle 21 is limited by the lock body protective block 3 and cannot continue to push into the clutch 11, thereby ensuring that the clutch structure is not damaged. Meanwhile, the lock body protection block 3 is movably connected to the through hole 112, meaning that no clutch structure is needed during assembly. Simply shorten the length of the insert 21 and install the lock body protection block 3 between the insert 21 and the clutch 11, reducing the difficulty and cost of production and assembly.

[0024] In some embodiments, the insertion depth of one end of the lock body protection block 3 into the clutch 11 is less than the depth of the slot 111. A gap is reserved between one end of the lock body protection block 3 and the bottom of the slot 111 to prevent the housing of the lock body 1 from deforming under the impact force of the insertion handle, which would cause the lock body protection block 3 to damage the clutch 11, thereby further ensuring the structural stability and security of the lock body 1.

[0025] In some embodiments, such as Figure 3 As shown, the other end of the lock body protection block 3 has an axisymmetric shape, and one side of the axisymmetric shape is a first arc surface 31. The two ends of the first arc surface 31 are a first straight surface 32 and a second straight surface 33 that are perpendicular to each other. The other side of the axisymmetric shape is a second arc surface 34 that is axially symmetrical with the first arc surface 31. The two ends of the second arc surface 34 are a third straight surface 35 and a fourth straight surface 36 that are perpendicular to each other. The first straight surface 32 is parallel to the third straight surface 35, and the second straight surface 33 is parallel to the fourth straight surface 36.

[0026] In this embodiment, the lock body protection block 3 is located between the upper and lower housings of the smart door lock. Therefore, its rotation is restricted by the space between the upper and lower housings. Thus, the lock body protection block 3 is set as two arc surfaces. In order to prevent the lock body protection block 3 from rotating excessively and causing the clutch 11 to be damaged due to excessive rotation, the two ends of the arc surfaces are set as straight surfaces. The upper and lower housings limit the straight surfaces to ensure that the lock body protection block 3 rotates within a suitable rotation angle range.

[0027] In some embodiments, such as Figure 3 As shown, the other end of the lock body protection block 3 is provided with a groove 37 that is adapted to the insertion handle 21. The insertion handle 21 is inserted into the groove 37, and the insertion depth is less than the depth of the groove 37.

[0028] In this embodiment, a gap is reserved between the insert 21 and the bottom of the groove 37 to allow the insert 21 to push into the clutch 11, thus creating a reserved impact and deformation space, preventing the groove 37 from being damaged by impact, and improving the service life of the lock body protection block 3.

[0029] In some embodiments, the insert 21 is provided with a first inlay pattern, and the groove 37 is provided with a second inlay pattern adapted to the first inlay pattern. The first and second inlay patterns can be set according to actual conditions and are not illustrated here. The insert 21 and the groove 37 are inlaid through the inlay pattern, which can improve the connection stability between the insert 21 and the groove 37.

[0030] In some embodiments, such as Figure 4As shown, a limiting baffle 4 is provided at the other end near the lock body protective block 3. The distance between the limiting baffle 4 and the other end of the lock body protective block 3 is not greater than the depth of the through hole 112. The limiting baffle 4 prevents the lock body protective block 3 from falling off the through hole 112 or from becoming too loose, thereby improving the stability of the lock body protective block 3 on the lock body body 1.

[0031] In some embodiments, the limiting baffle 4 is integrally formed with the outer shell of the lock body 1, or the limiting baffle 4 is fixedly connected to the shell of the smart lock. Preferably, the limiting baffle 4 is fixedly connected to the shell of the smart lock, so that after the lock body protective block 3 is installed on the lock body 1, the lock body 1 is then fixed to the shell of the smart lock, thereby facilitating assembly. It should be understood that the limiting baffle 4 is provided with a notch space for the insertion handle 21 to move.

[0032] In some embodiments, the lock body protection block 3 is made of hard plastic or metal to improve the service life and structural rigidity of the lock body protection block 3.

[0033] This utility model provides an intelligent door lock, which includes the above-described lock body structure.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
