Abstract
Description
Technical Field
[0001] The present application relates to the technical field of locks, and in particular to a door lock. Background Art
[0002] Door locks are generally equipped with a mechanical lock core, which is locked or unlocked by inserting a key into the lock core and rotating it. In related technologies, in order to improve the safety of the lock core, a lock core cover or other structure is provided at the lock core hole of the door lock housing to cover the lock core and hide the lock core. The lock core cover can also be equipped with electronic devices such as doorbell buttons and circuit boards. The conductive elements connected to these electronic devices need to be connected to the structural parts in the door lock housing. Therefore, the installation of the lock core cover must take into account the movement requirements of the lock core cover and the installation requirements of the conductive elements. If the lock core cover is installed on the housing with improper structural design, problems such as poor sealing and poor movement are likely to occur. In the process of turning the lock core cover, the conductive elements are easily pulled, and there is even a risk of the conductive elements breaking. Utility Model Content
[0003] An embodiment of the present application provides a door lock that can solve the problem that it is difficult to install a lock core cover structure while taking into account the movement requirements of the lock core cover structure and the installation requirements of the conductive element.
[0004] An embodiment of the present application provides a door lock, comprising:
[0005] a housing having a lock core hole;
[0006] Doorbell components, including doorbell buttons;
[0007] A lock core cover structure includes a body having an accommodating cavity therein, the doorbell button being arranged in the accommodating cavity, the body having a first mounting surface, the body being detachably mounted on the housing, and the first mounting surface facing the lock core hole;
[0008] Among them, the lock core cover structure also includes a guide member protruding from the first mounting surface, and the end of the guide member away from the first mounting surface is limitedly connected to the shell so that the body can move relative to the shell, thereby allowing the first mounting surface to avoid or cover the lock core hole.
[0009] According to the door lock of the embodiment of the present application, by setting one end of the guide member extending into the housing of the door lock and being limitedly connected to the housing, the body can be extended, retracted and rotated relative to the housing, so that the body can cover or expose the lock core hole. The guide member can guide the movement direction and movement position of the body and the structural member installed on the body, making the movement more stable, preventing the guide member from separating from the housing, limiting the extension range of the body relative to the housing, and preventing the guide member from moving too far relative to the housing and causing pulling. In addition, the interior of the guide member can be hollowed out to allow the conductive element inside the body to pass through the guide member and extend into the housing. Under the protection of the guide member, it is in an extended state, so that the conductive element inside the body can extend into the housing smoothly, preventing the conductive element from being stuck due to excessive movement range, thereby improving the smoothness of the entire movement process of the lock core cover structure.

[0027] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0028] The inventors discovered that when the lock cylinder cover structure contains electronic devices, the electronic devices are electrically connected to the conductive element, and the conductive element extends into the door lock and is electrically connected to other electronic devices or a power source within the door lock. Because the lock cylinder cover structure needs to be moved to cover or expose the lock cylinder, the conductive element is moved during movement, which can easily cause the conductive element to become loose, wrinkle, become stuck, or even break. Based on this, the present invention provides a door lock.
[0029] like Figure 1As shown, it is a schematic diagram of the three-dimensional structure of a door lock 20 according to an embodiment of the present application. The door lock 20 includes a lock core cover structure 10. The lock core cover structure 10 includes a main body 100. The main body 100 is used to be detachably arranged on the outer shell 21 of the door lock 20. The main body 100 has a first mounting surface, and the first mounting surface faces the lock core hole 20a of the door lock 20. A lock core 22 is installed in the lock core hole 20a of the door lock 20. When the main body 100 is installed on the outer shell 21 of the door lock 20, the first mounting surface covers the lock core hole 20a of the door lock 20. When a key needs to be inserted into the lock core 22 to lock or unlock, the main body 100 can be moved to remove the first mounting surface 1301 to expose the lock core 22.
[0030] The door lock 20 of the present embodiment further includes a doorbell assembly 200, which is installed inside the body 100. Specifically, Figure 2 As shown, the doorbell assembly 200 includes a doorbell button 210 and a conductive element 220 electrically connected to the doorbell button 210. The body 100 has an internal accommodating cavity 10a, and the doorbell button 210 is disposed within the accommodating cavity 10a. The doorbell button 210 is fixed relative to the body 100. The lock core cover structure 10 also includes a guide member 110 protruding from the first mounting surface 1301. The end of the guide member 110, which is away from the first mounting surface 1301, is positionally connected to the housing 21 of the door lock 20. The guide member 110 has a guide channel 101 that communicates with the accommodating cavity 10a. The conductive element 220 passes through the guide channel 101 and extends into the housing 21 of the door lock 20. The guide member 110 is configured to extend, retract, and rotate relative to the housing 21 of the door lock 20. When the guide member 110 moves relative to the housing 21 of the door lock 20, the entire lock core cover structure 10 moves together. When the guide member 110 is retracted relative to the housing 21 of the door lock 20, the first mounting surface 1301 of the main body 100 covers the lock core hole 20a. When the main body 100 is moved and the guide member 110 is extended relative to the housing 21 of the door lock 20, the main body 100 is continued to be rotated so that the guide member 110 rotates relative to the door lock 20, and the lock core hole 20a can be exposed.
[0031] In the present application, the position of the doorbell button 210 relative to the main body 100 is fixed, and the conductive element 220 electrically connected to the doorbell button 210 extends into the guide channel 101 of the guide member 110. The position of the guide member 110 relative to the accommodating cavity 10a is fixed, and the guide member 110 has a fixed shape. When the conductive element 220 passes through the guide channel 101 of the guide member 110, the guide member 110 can limit the range of movement of the conductive element 220, thereby improving the connection stability of the conductive element 220 connected to one end of the doorbell button 210. At the same time, the end of the guide member 110 away from the first mounting surface 1301 extends into the door lock 20, thereby guiding the conductive element 220 to also extend into the door lock 20. The guide member 110 can provide protection for the conductive element 220 throughout the entire process of the conductive element 220 extending into the door lock 20. The end of the guide member 110 away from the first mounting surface 1301 is also limitedly connected to the housing 21 of the door lock 20 to prevent the guide member 110 from separating from the housing 21 of the door lock 20. Therefore, it can also limit the extension and contraction range of the conductive element 220 relative to the housing 21 of the door lock 20, preventing the guide member 110 from moving too far relative to the housing 21 of the door lock 20 and causing tension on the conductive element 220. In addition, the guide member 110 limits the range of movement of the conductive element 220, allowing the conductive element 220 to remain in an extended state. It can also prevent the conductive element 220 from bending and causing jamming, thereby improving the smoothness of the entire movement of the lock core cover structure 10.
[0032] The body 100 has an extended state and a retracted state. Figure 3a and Figure 3b As shown, it is a structural diagram of the body 100 in the retracted state. In the retracted state, the guide member 110 is retracted relative to the housing 21 of the door lock 20, and the first mounting surface 1301 of the body 100 blocks the lock core hole 20a. Figure 4a and Figure 4b The figure is a structural diagram of the main body 100 in the extended state. In the extended state, the guide member 110 extends relative to the outer shell 21 of the door lock 20, and the guide member 110 is rotatable relative to the outer shell 21 of the door lock 20, that is, the main body 100 is rotatable relative to the outer shell 21 of the door lock 20. In the extending direction of the guide member 110, the first mounting surface 1301 of the main body 100 can block the lock core hole 20a, and the main body 100 can also be rotated so that the first mounting surface 1301 avoids the lock core hole 20a in the extending direction of the guide member 110.
[0033] When the body 100 is extended, the body 100 has a first position. In the first position, the distance between the first mounting surface 1301 and the lock core hole 20a in the extension direction of the guide member 110 is at its maximum, and the guide member 110 will no longer extend relative to the housing 21 of the door lock 20. The guide member 110 is retracted in a direction opposite to its extension direction. When the body 100 is retracted, the body 100 has a second position. In the second position, the distance between the first mounting surface 1301 and the lock core hole 20a in the extension direction of the guide member 110 is at its minimum, and due to the resistance of the housing 21 of the door lock 20, the guide member 110 will no longer retract relative to the housing 21 of the door lock 20. The travel of the body 100 between the first and second positions in the extension and retraction directions of the guide member 110 relative to the housing 21 is the telescopic travel of the conductive element 220.
[0034] like Figure 4a As shown, the lock core cover structure 10 further includes a limiting assembly 300. One end of the guide member 110 is movably disposed within the housing 21 of the door lock 20 and is connected to the limiting assembly 300. In a first position, the guide member 110 extends relative to the housing 21 of the door lock 20, and the limiting assembly 300 abuts against the inside of the housing 21 of the door lock 20. The stopper of the limiting assembly 300 prevents the guide member 110 from being separated from the housing 21 of the door lock 20. In the embodiment of the present application, the limiting assembly 300 can be arranged to be fixed relative to the guide member 110. In the first position, the limiting assembly 300 abuts against the inside of the housing 21 of the door lock 20. In the second position, the limiting assembly 300 is separated from the housing 21 of the door lock 20. The limiting assembly 300 can be installed at the position of the guide member 110 to limit the travel of the body 100 between the first position and the second position.
[0035] The guide member 110 has a first end 111 that extends into the housing 21 of the door lock 20. The conductive element 220 extends out of the guide member 110 at a surface of the first end 111 that faces away from the first mounting surface 1301. In some embodiments, the retaining assembly 300 includes a retaining washer 310 and a retaining nut 320. The retaining washer 310 is sleeved around the outer periphery of the guide member 110. The retaining nut 320 is threadedly connected to the first end 111 on a side of the retaining washer 310 that faces away from the first mounting surface 1301. In a first position, the retaining washer 310 abuts against the housing 21 of the door lock 20. The retaining washer 310 prevents the guide member 110 from separating from the housing 21 of the door lock 20 in the first position.
[0036] In some embodiments, the limiting washer 310 and the limiting nut 320 are mounted on the guide member 110 and fixed relative to the guide member 110 to prevent the limiting washer 310 and the limiting nut 320 from making any noise or collision when the guide member 110 is in motion. Figure 2 The limiting washer 310 is in contact with the first locking surface 1111 to prevent the limiting washer 310 from rotating around the guide member 110. The outer surface of the guide member 110 also includes a second locking surface 1112. The second locking surface 1112 is arranged at an angle to the first locking surface 1111, and the second locking surface 1112 is arranged at an angle to the extension direction of the guide member 110. After the limiting nut 320 is installed on the guide member 110, the limiting nut 320 abuts against the limiting washer 310, so that the limiting washer 310 abuts against the second locking surface 1112, preventing the limiting washer 310 from moving relative to the guide member 110 along the extension direction of the guide member 110.
[0037] In some embodiments, the guide member 110 moves relative to the housing 21 of the door lock 20 and drives the body 100 to move in a straight line direction to be retracted or extended relative to the housing 21, such as Figure 2 As shown, the guide member 110 extends along a predetermined direction A, which is perpendicular to the first mounting surface 1301. The first mounting surface 1301 is a plane, that is, the guide member 110 is rod-shaped. The guide member 110 is configured to move back and forth relative to the housing 21 of the door lock 20 along the predetermined direction A. The movement stroke is simple, facilitating smooth extension and retraction of the guide member 110. The housing 21 of the door lock 20 has a mounting hole, and the guide member 110 passes through the mounting hole and extends into the interior space of the housing 21. The outer surface of the guide member 110 slidably engages with the wall surface of the housing 21 defining the mounting hole, thereby guiding the guide member 110 to move smoothly and stably relative to the housing 21 of the door lock 20.
[0038] When the guide member 110 extends from the housing 21 of the door lock 20, the guide member 110 is configured to rotate about its axial direction relative to the housing 21 of the door lock 20. The outer contour of the portion of the guide member 110 through which the mounting hole is formed can be circular, allowing the guide member 110 to rotate directly about its axial direction relative to the housing 21 of the door lock 20. When the guide member 110 rotates about its axial direction relative to the housing 21 of the door lock 20, the entire body 100 also rotates about the guide member 110, and the body 100 rotates back and forth between a first rotational position and a second rotational position. In the first rotational position, the first mounting surface 1301 covers the lock core hole 20a, and in the second rotational position, the first mounting surface 1301 avoids the lock core hole 20a.
[0039] Of course, in other embodiments, the guide member 110 may be configured to move relative to the housing 21 of the door lock 20 and drive the body 100 to move in a curved direction to retract or extend relative to the housing 21. For example, the guide member 110 may be elliptical. When the guide member 110 moves relative to the housing 21 of the door lock 20, the trajectory of the movement of the body 100 is elliptical. When the body 100 gradually extends relative to the housing 21, the body 100 flips relative to the housing 21, gradually exposing the lock core hole 20a. The above description is merely illustrative. The embodiments of the present application do not limit the shape of the guide member 110. Any structure that can drive the body 100 to move smoothly in a curved direction when the guide member 110 moves relative to the housing 21 of the door lock 20 is applicable to the present application.
[0040] In some embodiments, the lock cylinder cover structure 10 further includes a positioning assembly (not shown in the figures), which includes a first positioning portion, a second positioning portion, and a third positioning portion. The first positioning portion is mounted on the body 100, and the second positioning portion and the third positioning portion are mounted on the housing 21 of the door lock 20. In the first rotational position of the body 100, the first positioning portion corresponds to the second positioning portion, and one of the first positioning portion and the second positioning portion is magnetic, and the other is magnetic or contains an iron material, so that the first positioning portion and the second positioning portion are magnetically attracted to each other, thereby positioning the body 100 relative to the housing 21 in the first rotational position. In the second rotational position of the body 100, the first positioning portion corresponds to the third positioning portion, and one of the first positioning portion and the third positioning portion is magnetic, and the other is magnetic or contains an iron material, so that the first positioning portion and the third positioning portion are magnetically attracted to each other, thereby positioning the body 100 relative to the housing 21 in the second rotational position.
[0041] The body 100 includes a mounting base 130 having a first mounting surface 1301, wherein the first positioning portion can be mounted on the mounting base 130. The guide member 110 is protruding from the first mounting surface 1301 of the mounting base 130. The first mounting surface 1301 of the mounting base 130 defines a wire hole 1311. The wire hole 1311 extends to communicate with the accommodating cavity 10a, allowing the conductive element 220 to enter the guide channel 101 directly from the accommodating cavity 10a. The guide member 110 has a second end 112 disposed opposite the first end 111. The guide channel 101 extends from the second end 112 to the first end 111 to penetrate the guide member 110. The end surface of the second end 112 of the guide member 110 faces the first mounting surface 1301 so that the guide channel 101 is aligned with the wire hole 1311. The position of the guide member 110 relative to the mounting seat 130 is fixed, facilitating sealing of the gap between the guide member 110 and the mounting seat 130, thereby sealing the junction between the wire hole 1311 and the guide channel 101. In other embodiments, the guide member 110 and the mounting seat 130 may be directly integrated, with no gap between them.
[0042] Since the guide member 110 needs to move relative to the outer shell 21 of the door lock 20, there is also a situation where water vapor enters the interior of the outer shell 21 from the gap between the guide member 110 and the outer shell 21 of the door lock 20. The main body 100 is provided to also include a first sealing ring 150, and the wall surface of the outer shell 21 includes a docking surface 211. The first sealing ring 150 is configured to be able to abut against the docking surface 211 when the first mounting surface 1301 covers the position of the lock core hole 20a, so as to seal the gap between the main body 100 and the outer shell 21.
[0043] In some embodiments, the first sealing ring 150 is sleeved on the periphery of the mounting seat 130. When the guide member 110 moves smoothly relative to the outer shell 21 of the door lock 20, the first mounting surface 1301 is used to cover the lock core hole 20a, and the guide member 110 is protruded from the first mounting surface 1301. The first sealing portion 150 is directly sleeved on the periphery of the first mounting seat 130. When the guide member 110 is retracted relative to the outer shell 21, the first sealing ring 150 is set to abut against the surface of the outer shell 21, so as to seal the area outside the first mounting surface 1301, thereby preventing water vapor from entering the interior of the outer shell 21. The sealing and waterproof performance is good, and there is no need for a sealing and waterproof design between the outer shell 21 and the guide member 110.
[0044] The main body 100 also includes a button cap 140, which is movably mounted on the mounting base 130. A accommodating cavity 10a is defined between the button cap 140 and the mounting base 130. The doorbell button 210 is mounted on one of the button cap 140 and the mounting base 130. When the mounting base 130 and the button cap 140 are close to each other, the other of the mounting base 130 and the button cap 140 acts on the doorbell button 210 to trigger a doorbell signal, thereby prompting the user.
[0045] The body 100 further includes a second sealing ring 160, which is connected to the key cap 140 and the mounting base 130 to seal the gap between the key cap 140 and the mounting base 130. Figure 5As shown, the key cap 140 includes a key cap body 141 and a first flange 142, the mounting base 130 includes a base body 131 and a second flange 132, the base body 131 has a first mounting surface 1301 and a second mounting surface 1302 arranged opposite to each other, the second flange 132 is protruded from the second mounting surface 1302 of the base body 131, and the second flange 132 extends into the space enclosed by the first flange 142. The key cap body 141 is arranged opposite to the base body 131, and the first flange 142 is protruded. The surface of the keycap body 141 facing the base body 131 and the surface of the keycap body 141 facing away from the base body 131 are used for users to touch, so that when the user presses the keycap body 141, the keycap 140 and the mounting base 130 can move closer to each other to trigger the doorbell button 210. The second sealing ring 160 is sleeved on the outer periphery of the second flange 132, and the second sealing ring 160 abuts against the inner side surface of the first flange 142 to seal the gap between the first flange 142 and the second flange 132.
[0046] The doorbell assembly 200 further includes a circuit board 230. The doorbell button 210 is mounted on the circuit board 230 and is electrically connected to the circuit board 230. There is at least one conductive element 220, which can be electrically connected to the doorbell button 210 and the circuit board 230. In other embodiments, the accommodating cavity 10a may also include electronic components such as lamp beads and fingerprint sensors. These electronic components can all be electrically connected to the circuit board 230 and extend through the conductive element 220 into the housing 21 of the door lock 20 to be electrically connected to a power source or control system. The circuit board 230 is mounted on the base 131 of the mounting base 130, and the doorbell button 210 is mounted on the surface of the circuit board 230 facing the keycap body 141. The keycap body 141 moves toward the mounting base 130 to act on the doorbell button 210 to trigger a doorbell signal.
[0047] The lock core cover structure 10 also includes a mating component, which includes a first mating portion, a second mating portion 520 and an elastic member 530. The first mating portion is protruding from the surface of the keycap body 141 facing the seat body 131. The first mounting surface 1301 of the mounting seat 130 is provided with a mating opening 1312, and the mating opening 1312 extends to the second mounting surface 1302. The second mating portion 520 is passed through the mating opening 1312 and is connected to the first mating portion. The second mating portion 520 also has a convex cap 521, which does not enter the mating opening 1312, and the convex cap 521 is used to fit with the first mounting surface 1301 to prevent the second mating portion 520 from entering the accommodating cavity 10a from the mating opening 1312. One end of the elastic member 530 is connected to the first matching portion or the button cap 140, and the other end of the elastic member 530 is connected to the mounting base 130 or the second matching portion 520, so that after the button cap 140 and the mounting base 130 are brought close to each other each time, the elastic member 530 pushes the button cap 140 to reset, so that the button cap 140 is separated from the doorbell button 210.
[0048] In some embodiments, the first mounting surface 1301 of the mounting base 130 has a geometric center, and the doorbell button 210 can be set corresponding to the geometric center of the first mounting surface 1301. The number of mating components is multiple groups, and the multiple groups of mating components are set around the geometric center of the first mounting surface 1301, so that the multiple groups of mating components can act evenly on the button cap 140, so that the button cap 140 can move more smoothly relative to the mounting base 130.
[0049] The main body 100 also includes a reinforcing plate 120, which is sleeved on the periphery of the guide member 110 and is integrally arranged with the guide member 110. The reinforcing plate 120 is connected to the first mounting surface 1301, and the reinforcing plate 120 is fixed to the mounting seat 130, thereby fixing the position of the guide member 110 relative to the mounting seat 130. The reinforcing plate 120 has a large contact area with the first mounting surface 1301, which can effectively improve the stability of the guide member 110 installed on the mounting seat 130, and prevent the guide member 110 from being separated or broken from the mounting seat 13 due to the small contact area between the guide member 110 and the mounting seat 130.
[0050] When the guide member 110 is retracted relative to the housing 21 of the door lock 20, the reinforcement plate 120 has a reinforcement surface 121 facing away from the first mounting surface 1301. The reinforcement surface 121 is flat and in contact with the surface of the housing 21, thereby enhancing the smoothness of the fit between the reinforcement plate 120 and the housing 21 of the door lock 20. The reinforcement surface 121 of the reinforcement plate 120 also defines a clearance opening 122 extending through the reinforcement plate 120. The protruding cap 521 of the second mating portion 520 protrudes from the first mounting surface 1301 and is retracted within the clearance opening 122 to prevent the protruding cap 521 from interfering with the stability of the mounting base 130 when mounted on the housing 21 of the door lock 20.
[0051] In some embodiments, the reinforcement plate 120 completely covers the first mounting surface 1301, further increasing the contact area between the reinforcement plate 120 and the first mounting surface 1301, providing more comprehensive support for the mounting base 130, and preventing deformation of the mounting base 130. The first sealing ring 150 further extends and connects to the reinforcement plate 120, allowing the reinforcement plate 120 to provide support for the first sealing ring 150 and improve the installation stability of the first sealing ring 150.
[0052] In some embodiments, the reinforcing plate 120 is fixed to the mounting base 130 by screwing. Specifically, Figure 5 As shown, a plurality of positioning posts 133 are protruding from the second mounting surface 1302 of the mounting base 130. Each positioning post 133 is coaxially provided with an internally threaded hole with the reinforcing plate 120. A reinforcing screw 134 is installed in the internally threaded hole to secure the reinforcing plate 120 to the mounting base 130. The positioning posts 133 for securing the reinforcing plate 120 are protruding from the second mounting surface 1302 of the mounting base 130, fully utilizing the space between the button cap 140 and the mounting base 130. At the same time, with the support of the reinforcing plate 120, the thickness of the base 131 of the mounting base 130 is reduced.
[0053] When the circuit board 230 is mounted on the mounting base 130, the surface of the circuit board 230 is in contact with the second mounting surface 1302 of the mounting base 130. The circuit board 230 is sleeved around the periphery of the plurality of positioning posts 133. The plurality of positioning posts 133 guide the circuit board 230 for rapid alignment, preliminarily defining the position of the circuit board 230, and then the circuit board 230 is fixed to the mounting base 130. Optionally, the circuit board 230 is fixed to the mounting base 130 using screws. In some other embodiments, the circuit board 230 may also be fixed to the mounting base 130 using other methods. The present embodiment does not limit the method for fixing the circuit board 230 to the mounting base 130, and the specific method can be selected according to actual needs.
[0054] In some embodiments, the outer contour of the first mounting surface 1301 of the mounting seat 130 is circular. In this case, the center of the first mounting surface 1301 having a circular outer contour is the geometric center of the first mounting surface 1301. The guide member 110 is disposed offset from the center of the outer contour of the mounting seat 130. When the guide member 110 is retracted relative to the housing 21, the eccentrically disposed guide member 110 can restrict the mounting seat 130 from rotating about the guide member 110.
[0055] The door lock 20 provided in the embodiment of the present application is intended to be installed on a door, which can be at least one of a room door, an electronic device door, and a transportation device door. The door lock 20 can be a door lock 20 that is locked or unlocked solely by inserting a key into a lock cylinder 22. The door lock 20 can also be a door lock 20 that is locked or unlocked solely by inserting a key into the lock cylinder 22 and that also integrates other electronic devices for locking or unlocking. For example, the door lock 20 can be a smart door lock 20 that can be locked or unlocked electronically using an IC card, a digital password, fingerprint recognition, Bluetooth technology, mobile terminal wireless technology, or facial recognition.
[0056] The door lock 20 includes a housing 21, a lock cylinder 22, and the lock cylinder cover structure 10 described above. The housing 21 is intended to be mounted on the door and has a lock cylinder hole 20a. The lock cylinder 22 is positioned within the housing 21 in correspondence with the lock cylinder hole 20a. The mounting base 130 of the lock cylinder cover structure 10 covers the lock cylinder hole 20a and is removably connected to the housing 21, concealing the lock cylinder 22. By removing the lock cylinder cover structure 10, a key can be inserted into the lock cylinder 22 to lock or unlock the door. Furthermore, electronic components such as the doorbell button 210 are mounted within the accommodating cavity 10a of the lock cylinder cover structure 10, giving the lock cylinder cover structure 10 multiple functions and enhancing the appearance of the door lock 20.
[0057] The housing 21 also has a mounting groove 20b connected to the lock core hole 20a. The lock core hole 20a is opened on the bottom wall of the mounting groove 20b, and the bottom wall of the mounting groove 20b is also opened with a mounting hole. The first end 111 of the guide member 110 passes through the mounting hole and extends into the internal space of the housing 21, and is connected to the limiting component 300 provided in the internal space of the housing 21. The limiting component 300 contacts the inner wall surface of the housing 21 to prevent the guide member 110 from separating from the housing 21.
[0058] When the guide member 110 is retracted relative to the housing 21 of the door lock 20, part of the main body 100 of the lock core cover structure 10 is accommodated in the mounting groove 20b, and the first mounting surface 1301 of the mounting seat 130 covers the lock core hole 20a. The main body 100 and the wall surface of the mounting groove defined by the housing 21 abut against each other. Specifically, the side wall surface of the mounting groove 20b forms a docking surface 211, and the first sealing ring 150 of the main body 100 abuts against the docking surface 211 of the housing 21, sealing the gap between the main body 100 and the wall surface of the mounting groove 20b to prevent water vapor from entering the lock core hole 20a. At the same time, it is convenient to move the main body 100 so that the guide member 110 extends relative to the housing 21.
[0059] In one embodiment of the present application, the lock core cover structure 10 can be installed on the housing 21 in the following manner:
[0060] First, the first sealing ring 150 is mounted on the periphery of the seat body 131 of the mounting seat 130, and the second sealing ring 160 is mounted on the periphery of the first flange 132 of the mounting seat 130.

The surface of the reinforcing plate 120 is fitted into the first mounting surface 1301 of the mounting seat 130, and the reinforcing plate 120 is fixed to the seat body 131.
[0061] Then, the circuit board 230 is fixed to the base 131, and the conductive element 220 is passed through the wire hole 1311 and the guide channel 101 in sequence, and is led out from the first end of the guide member 110; then, the key body 141 of the key cap 140 is arranged opposite to the base 131, one end of the elastic member 530 is sleeved on the periphery of the first guide part and fixed to the first guide part, and the other end is sleeved on the periphery of the second guide part 520, and the second guide part 520 is penetrated from the side where the first mounting surface 1301 is located to penetrate into the accommodating cavity and be threadedly connected to the first guide part. At the same time, the second flange 142 of the key cap 140 is sleeved on the periphery of the second sealing ring 160 and abuts against the second sealing ring 160.
[0062] Finally, the first end 111 of the guide member 110 is passed through the mounting hole of the housing 21, the limiting washer 310 is sleeved on the outer periphery of the first end 111 of the guide member 110, and the limiting nut 320 is installed on the first end 111 of the guide member 110 to complete the assembly.
