[0041] A door lock is a type of lock installed on a door body. Generally, a door lock includes a front panel assembly, a rear panel assembly, and a lock body assembly located between the two, so as to enable the lock body assembly to be locked and unlocked through both the front panel assembly and the rear panel assembly.
[0042] However, during the actual installation of a door lock, due to different door bodies having different thicknesses, it is inevitable that the lock core in the lock body assembly embedded in the door body cannot be properly inserted into the lock core hole of the front panel assembly installed on the outer side of the door body. That is, there is a gap formed at the lock core hole of the lock body assembly and the front panel assembly. At this time, an external person can insert an external object through the lock core hole of the front panel assembly into the door lock to drive and control the unlocking of the lock body assembly by the square shaft of the door lock, thereby reducing the security of the door lock during use.
[0043] Therefore, based on the above considerations, in order to solve the problem of the relatively low anti-theft level of current door locks, this application proposes a new type of front panel assembly for door locks. This front panel assembly innovatively inserts a slidable protective sleeve into the lock core hole of the body, so as to adaptively sleeve the protective sleeve onto the lock core of the lock body assembly according to the thickness types of different door bodies, thereby closing the gap between the lock core and the lock core hole of the front panel assembly and improving the anti-theft level of the door lock.
[0044] Next, the structure of the front panel assembly proposed in this application will be explained and described with embodiments. In an embodiment of this application, please refer to Figures 1 to 5The front panel assembly 100 proposed in the present application includes a body 10 and a protective assembly 30; the body 10 is provided with a lock core hole 11; the protective assembly 30 includes a protective sleeve 31 and an elastic member 33, one end of the protective sleeve 31 can be slidably inserted into the lock core hole 11, and the elastic member 33 is arranged between the body 10 and the protective sleeve 31; one of the protective sleeve 31 and the body 10 is provided with a guide column 317, and the other one is provided with a guide hole 13, the guide column 317 is extended along the sliding direction of the protective sleeve 31, and can be slidably inserted into the guide hole 13.
[0045] The body 10 can be used to provide an installation position to install and carry the protection component 30 and other components in the front panel component 100, such as a circuit board or a communication module, so as to facilitate the assembly of the various components in the front panel component 100 to form a whole for use. Among them, when the front panel component 100 is in a normal use and installation state, the projection of the body 10 in the vertical plane can be a rectangle, of course, it can also be a waist shape or an ellipse, etc., and the present application does not limit the shape of the body 10. Further, the lock core hole 11 provided on the body 10 can be used for the key to pass through, so that the key can be inserted into the key hole of the lock core 330 provided in the lock body component 300 corresponding to the lock core hole 11 to realize the mechanical unlocking of the door lock. Of course, the front panel component 100 in this solution can also be used for electronic unlocking. Specifically, the body 10 can be provided with a handle or a motor drive module, and the body 10 can also be provided with a clutch mechanism. When the front panel assembly 100 receives accurate password information or fingerprint information, the clutch mechanism can establish transmission with the square shaft 500 passing through the lock body 310. At this time, the square shaft 500 can be driven to rotate by the handle or the motor drive module, and then the lock core 330 can be driven to unlock by the square shaft 500.
[0046] The protective assembly 30 is slidably inserted into the lock core hole 11 through one end of the protective sleeve 31, so that the other end of the protective sleeve 31 can protrude from the opening of the lock core hole 11. At this time, the protective sleeve 31 can "extend" the lock core hole 11 of the body 10, so as to be inserted and matched with the end of the lock core 330 in the lock body assembly 300 close to the front panel assembly 100, thereby enclosing and isolating the gap between the lock core 330 and the lock core hole 11 of the body 10, and preventing foreign objects from extending into the inner side of the door lock through the gap between the lock core 330 and the lock core hole 11 of the body 10, such as Figure 9Schematic diagram of the installation and adaptation of the front panel body 100 and the lock body assembly 300 shown on the door body 700. Among them, in the sliding direction of the protective sleeve 31, the projected shape of the lock core hole 11, the shape of the protective sleeve 31, and the shape of the lock core 330 can be the same. Of course, it can also be that only the inner side of the protective sleeve 31 and the shape of the lock core 330 are the same, and the outer side of the protective sleeve 31 is the same as the shape of the lock core hole 11. Further, an elastic force can be applied to the protective sleeve 31 through the elastic member 33, so that the protective sleeve 31 can perform elastic expansion and contraction during the sliding process, and thus can adapt to the distance between the body 10 and the lock body assembly 300 when applied to the installation of door bodies 700 with different thicknesses. Among them, the elastic member 33 can be a spring, so that the elastic member 33 can have good elastic performance. At the same time, it can also make the cost of the elastic member 33 relatively low and convenient to obtain in the market. Of course, the present application is not limited to this. In other embodiments, the elastic member 33 can also be a shrapnel, etc. In addition, the elastic member 33 can have a connection relationship with both the body 10 and the protective sleeve 31, for example: welding connection, bonding connection or hook connection, etc. Of course, the elastic member 33 can also only have an abutting relationship with the body 10 and the protective sleeve 31. Further, the guide post 317 and the guide hole 13 can play a guiding role in the sliding of the protective sleeve 31. Among them, the guide post 317 can be arranged on the protective sleeve 31, and the guide hole 13 can be arranged on the body 10; of course, it can also be that the guide post 317 is arranged on the body 10 and the guide hole 13 is arranged on the protective sleeve 31. In addition, the guide post 317 can be located inside the body 10, for example: inside the lock core hole 11 or inside other holes. Of course, the guide post 317 can also be located outside the body 10.
[0047] Since the front panel assembly 100 of the technical solution of the present application is provided with a protective assembly 30 including a protective sleeve 31 and an elastic member 33, and the protective sleeve 31 is slidably inserted into the lock core hole 11 of the body 10. In this way, when the front panel assembly 100 is installed on door bodies 700 with different thicknesses, and there are different distances between the front panel assembly 100 located outside the door body 700 and the lock body assembly 300 embedded inside the door body 700, the slidable setting of the protective sleeve 31 and the cooperative setting of the elastic member 33 can enable the protective sleeve 31 to expand and contract and fitly sleeve the end of the lock core 330 in the lock body assembly 300 close to the front panel assembly 100 to close the gap between the lock core 330 and the body 10 of the front panel assembly 100, such as Figure 9The schematic diagram of the installation and adaptation of the front panel body 100 and the lock body assembly 300 shown on the door body 700 is provided, thereby preventing external personnel from reaching into the door lock through the lock core hole 11 of the front panel assembly 100 with external objects to drive and unlock the square shaft 500 of the door lock, thus improving the security of the door lock during use. Further, the cooperative setting of the guide post 317 and the guide hole 13 can play a guiding role in guiding the protective sleeve 31, so as to improve the accuracy of the sliding direction and the sliding stability of the protective sleeve 31, and further facilitate improving the installation accuracy of the front panel assembly 100 on the door body 700.
[0048] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the guide post 317 is provided on the protective sleeve 31, and the guide hole 13 is provided on the body 10; the body 10 is further provided with an avoidance cavity 15 communicating with the guide hole 13, and the guide post 317 can slide in the avoidance cavity 15.
[0049] In this embodiment, the guide post 317 is arranged on the protective sleeve 31, and the guide hole 13 is arranged on the body 10, so that the guide post 317 can also slide and expand on the body 10, which is beneficial to improving the compactness of the mechanism distribution, so that the overall size of the front panel assembly 100 in the sliding direction of the protective sleeve 31 is relatively low and does not affect subsequent installation. Further, an avoidance cavity 15 is provided on the body 10, which can be used to provide a movement space for the guide post 317 when it slides following the protective sleeve 31.
[0050] Please refer to Figures 3 to 5 , in an embodiment of the present application, the protection component 30 further includes a stopper 35, the stopper 35 is arranged on the guide post 317 and is located in the avoidance cavity 15, and the stopper 35 abuts against the cavity wall of the avoidance cavity 15 penetrated by the guide hole 13.
[0051] In this embodiment, the sliding stroke of the protective sleeve 31 can be limited by the stopper 35, so as to reduce the possibility that the protective sleeve 31 is driven out of the lock core hole 11 by the elastic member 33, which is beneficial to improving the installation stability of the protection component 30 on the body 10. In addition, a structural basis is provided at this time, so that in some embodiments, the two ends of the elastic member 33 can be respectively abutted against the body 10 and the protective sleeve 31, which can also ensure the stability of the protective sleeve 31 on the body 10. At this time, the elastic member 33 only has an abutting relationship with the body 10 and the protective sleeve 31, which can simplify the structure of the front panel assembly 100, improve the manufacturing convenience of the front panel assembly 100 and reduce the manufacturing cost of the front panel assembly 100. At the same time, it is also beneficial to improve the assembly convenience of the front panel assembly 100.
[0052] Please refer to Figures 3 to 5In one embodiment of the present application, the stopper 35 includes a screw 351 , and the screw 351 is threadedly connected to the guide column 317 .
[0053] In this embodiment, the stopper 35 is set as a screw 351, so that the stopper 35 and the guide column 317 can be manufactured separately and independently, and can be assembled by a relatively simple threaded connection method, thereby improving the convenience of manufacturing the protective component 30 and the stability and convenience of assembly. Among them, the stopper 35 can be abutted against the cavity wall of the avoidance cavity 15 penetrated by the guide hole 13 through the screw 351 to play a limiting role. Of course, the stopper 35 can also further include a gasket 353. At this time, the gasket 353 can be clamped between the screw 351 and the guide column 317, so as to play a limiting role through the gasket 353 abutting against the cavity wall of the avoidance cavity 15 penetrated by the guide hole 13. Alternatively, in some embodiments, the stopper 35 can also be an integral structure with the guide column 317. Or it can be a set of ring structures and clamped in the annular groove of the guide column 317.
[0054] Please refer to Figures 3 to 8 In one embodiment of the present application, the lock core hole 11 includes a first hole body 111 and a second hole body 113, the first hole body 111 and the second hole body 113 are arranged side by side and connected, in the sliding direction of the protective sleeve 31, the first hole body 111 passes through the two opposite sides of the body 10, and the second hole body 113 passes through one side of the body 10; the protective sleeve 31 includes a first sleeve 311 and a second sleeve 313, the first sleeve 311 and the second sleeve 313 are arranged side by side and connected, in the sliding direction of the protective sleeve 31, both ends of the first sleeve 311 are open, and one end of the second sleeve 313 is open; the second sleeve 313 has a first wall surface 315 opposite to the opening of the second sleeve 313, the guide column 317 is convexly arranged on the side of the first wall surface 315 away from the opening of the second sleeve 313, the guide hole 13 is connected to the second hole body 113, and the elastic member 33 is arranged between the body 10 and the first wall surface 315.
[0055] In this embodiment, the lock core hole 11 is set to include a first hole body 111 and a second hole body 113, and the protective sleeve 31 is set to include a first sleeve 311 and a second sleeve 313, which can make the shapes of the lock core hole 11 and the protective sleeve 31 the same as those of the lock core 330 in the lock body assembly 300 on the market (that is, the projections of the lock core hole 11, the protective sleeve 31, and the lock core 330 in the sliding direction of the protective sleeve 31 can all include two relatively parallel straight line segments, as well as a first arc segment and a second arc segment located at both ends of the two straight line segments. The two ends of the first arc segment can be respectively connected to the same end of the two straight line segments, the two ends of the second arc segment can be respectively connected to the other same end of the two straight line segments, and the radius of the first arc segment can be greater than the radius of the second arc segment, and the radius of the second arc segment can be equal to the distance between the two straight line segments). Further, it is beneficial to improve the tightness of the fit between the lock core hole 11, the protective sleeve 31, and the lock core 330, so as to further improve the isolation and protection effect of the protective sleeve 31 on the lock core 330. Further, the first hole body 111 penetrates through the opposite sides of the machine body 10, which can facilitate the passage of the key to be inserted into the key hole corresponding to the first hole body 111 on the lock core 330 in the lock body assembly 300. The second hole body 113 only penetrates through one side of the machine body 10, which can facilitate the installation of the elastic member 33 and the setting of the guide post 317 in the second hole body 113, so as to improve the compactness of the distribution between the protective component 30 and the machine body 10. Wherein, it is defined that the machine body 10 has an opposite operating surface 10a and a rear surface 10b. When the front panel assembly 100 is in the normal use installation state, the operating surface 10a can face away from the door body 700 and towards the user. At this time, both ends of the first hole body 111 can penetrate through the operating surface 10a and the rear surface 10b of the machine body 10, and one end of the second hole body 113 can penetrate through the rear surface 10b of the machine body 10.

At this time, the guide hole 13 and the avoidance cavity 15 are provided at the end of the extension post 171 away from the second wall surface 17, which can make the guide hole 13 and the avoidance cavity 15 relatively close to the first wall surface 315. Further, the length of the guide post 317 does not need to be set relatively long, so as to further improve the compactness of the distribution between the protective component 30 and the machine body 10. Among them, the avoidance cavity 15 can be entirely provided on the extension post 171. Of course, it can also be partially provided on the extension post 171 and the other part is provided on other components of the machine body 10.
[0058] Please refer to Figures 3 to 5 , in an embodiment of the present application, the elastic member 33 is sleeved on the extension column 171.
[0059] In this embodiment, the elastic member 33 is sleeved on the outside of the extension column 171, so that the extension column 171 can guide the elastic force direction of the elastic member 33, which is beneficial to improving the accuracy and stability of the elastic force exerted by the elastic member 33 on the protective sleeve 31. At the same time, such a setting can also improve the compactness of the distribution of the elastic member 33 and the extension column 171.
[0060] Please refer to Figure 7 , in an embodiment of the present application, the first sleeve 311, the second sleeve 313 and the guide post 317 are of an integral structure.

[0062] Please refer to Figure 1 , Figure 3 and Figure 4 , in an embodiment of the present application, the front panel assembly 100 further includes a covering member 50, the covering member 50 is arranged on one side of the body 10 away from the orifice of the second hole body 113, and can open and cover the orifice of the first hole body 111.
[0063] In this embodiment, by arranging the covering member 50 on the operating side of the body 10, when the key is not needed to unlock, it can cover the orifice of the first hole body 111 on the operating surface 10a of the body 10, thereby reducing the possibility of damage caused by foreign objects. Among them, a groove may be provided on the operating surface 10a of the body 10, and the first hole body 111 communicates with the groove. At this time, the covering member 50 can be an object that can elastically deform such as a silica gel member or a rubber member, and can be set in an interference fit that is separable from the groove. Of course, the covering member 50 can also be fixedly connected or rotatably connected to the body 10 at one end, so that after the covering member 50 opens the orifice of the first hole body 111, it can still have a connection relationship with the body 10 without additional holding or placement. Or, in some embodiments, the covering member 50 can also be a rigid object, and one end is rotatably connected to the body 10, and the other end can be detachably connected to the body 10 by magnetic connection or snap connection. It can be seen that the present application does not limit the installation method of the covering member 50 on the body 10, as long as it can open and cover the orifice of the first hole body 111.
[0064] The present application also provides a door lock, which includes a front panel assembly 100. The specific structure of the front panel assembly 100 may refer to the above embodiments.
