[0047] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or a solution in which both A and B are satisfied. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0052] A door lock is a lock that is installed on a door. It typically consists of a front panel assembly, a rear panel assembly, and a lock body assembly located between them. This allows the lock body assembly to be locked and unlocked via both the front and rear panels. To protect the battery in the door lock, it is typically installed within the rear panel assembly, preventing it from being removed from the outside of the door.

[0053] However, when installing batteries in related technologies, the batteries are usually directly adapted and installed in the installation cavity, so that the battery is abutted and limited by the cavity wall of the installation cavity. At this time, there are some disadvantages in using the installation cavity to adapt the installation of the battery. For example: Disadvantage 1, due to the existence of processing errors and assembly errors, it is difficult for the battery and the installation cavity to maintain size consistency, that is, a gap is likely to appear between the two, and the stability of the battery installation is not high. Disadvantage 2, if the size of the installation cavity is set to be smaller, although it can abut and limit the battery, it will cause hard pressure damage to the battery, causing the battery to be easily damaged during installation.

[0054] Therefore, based on the above considerations, and in order to address the problem of batteries in current door locks being prone to instability and damage during installation, this application proposes a novel rear panel assembly for use in door locks. This rear panel assembly innovatively includes a fixing member made of an elastically deformable material, and the fixing member and the body cooperate to clamp the battery within the installation cavity. The fixing member's elastically adapted contact with the battery improves the stability of the battery installation while preventing physical damage to the battery.

[0055] Next, the structure of the rear panel assembly proposed in this application is explained and described with an embodiment. In one embodiment of this application, please refer to Figures 1 to 6 The rear panel assembly 100 proposed in this application includes a body 10, a battery 30, and a fixing member 50. The body 10 defines a mounting cavity 11; the battery 30 is disposed within the mounting cavity 11; and the fixing member 50 is disposed within the body 10 and at least partially within the mounting cavity 11. The fixing member 50 is made of an elastically deformable material and cooperates with the body 10 to clamp the battery 30.

[0056] The body 10 provides a mounting location for the battery 30 and other components of the rear panel assembly 100, such as the handle 70, circuit board, motor, or communication module, thereby facilitating assembly of the components of the rear panel assembly 100 into a single unit for use. When the rear panel assembly 100 is in normal use, the projection of the body 10 on a vertical plane can be rectangular, though it can also be waist-shaped or oval. This application does not limit the shape of the body 10. The mounting cavity 11 provided on the body 10 is used to mount the battery 30. The shape of the mounting cavity 11 can be the same as that of the battery 30. For example, when the rear panel assembly 100 is in normal use, the projection of the mounting cavity 11 and the battery 30 on a vertical plane can be any shape, such as a square or rectangle, to enhance the compactness of the arrangement between the body 10 and the battery 30. Furthermore, the mounting cavity 11 can be a closed cavity or can be open. In addition, the number of mounting cavities 11 can be one, so that one battery 30 can be installed through the mounting cavity 11; of course, at least two batteries 30 can be installed through the mounting cavity 11. Alternatively, the number of mounting cavities 11 can also be at least two, so that one battery 30 can be installed through each mounting cavity 11.

[0057] The battery 30 can be used to power the electrical components in the door lock. The electrical components include the electrical components in the front panel assembly, and may also include the electrical components in the rear panel assembly 100, such as: a circuit board (which can be set on the front panel assembly and / or the rear panel assembly 100), a motor (which can be set on the front panel assembly and / or the rear panel assembly 100), a display module (which can be set on the front panel assembly and / or the rear panel assembly 100), a button (which can be set on the front panel assembly and / or the rear panel assembly 100), a communication module (which can be set on the front panel assembly and / or the rear panel assembly 100) or a camera recognition module (which can be set on the front panel assembly), etc. It can be seen that the present application does not limit the power supply object of the battery 30, as long as it is a device in the door lock that needs to be powered. In addition, the battery 30 can be any shape such as a cube or a rectangular parallelepiped. In addition, the number of batteries 30 can be one, or of course, at least two.

[0058] The fixing member 50 is made of an elastically deformable material, meaning it can be reset after deformation. The fixing member 50 can be made of silicone, which allows it to have both good elasticity, allowing it to adapt to the abutment and position-limiting battery 30 through elastic deformation, and a certain strength to improve the abutment and position-limiting stability of the fixing member 50. Of course, the present application is not limited to this. In other embodiments, the fixing member 50 can also be made of rubber or other elastically deformable materials. Furthermore, the fixing member 50 can be disposed on the outside of the body 10 and partially extend into the mounting cavity 11. Of course, the fixing member 50 can also be disposed entirely within the mounting cavity 11. Furthermore, the fixing member 50 and the body 10 can only clamp the battery 30 on two opposing sides in one direction, such as one of the first, second, and third directions described below. Of course, the fixing member 50 and the body 10 can also clamp the battery 30 on two opposing sides in at least two directions, such as at least two of the first, second, and third directions. When the rear panel assembly 100 is in normal use and installation, the first and third directions may be two intersecting horizontal directions, and the second direction may be a vertical direction. Furthermore, the fixing member 50 may be a plate structure, a column structure, or a combination of a plate and a column structure. This application does not limit the structural type and shape of the fixing member 50.

[0059] When the rear panel assembly 100 of the technical solution of the present application is used, after the battery 30 is installed in the installation cavity 11 of the body 10, the battery 30 can be clamped by the fixing member 50 and the body 10. At this time, since the material of the fixing member 50 is an elastically deformable material, it can be elastically abutted against the battery 30 in an adaptive manner through elastic deformation according to the installation situation of the battery 30 in the installation cavity 11. This reduces the possibility of the battery 30 being unable to adapt and be accommodated in the installation cavity 11 due to processing errors and assembly errors, thereby helping to improve the stability of the battery 30 installed on the body 10. Moreover, by elastically abutting and limiting the battery 30 with the fixing member 50 made of an elastically deformable material, the possibility of hard pressure damage to the surface of the battery 30 can also be reduced, thereby helping to improve the safety of the battery 30 installation.

[0060] Please refer to Figure 4 、 Figures 6 to 8 ,as well as Figure 10 In one embodiment of the present application, the body 10 has a first side 12 and a second side 13 that are arranged back to back. The rear panel assembly 100 also includes a handle 70, which is arranged on the first side 12; the fixing member 50 is arranged on the second side 13, and the body 10 has a clearance hole 14 connected to the installation cavity 11. A portion of the fixing member 50 passes through the clearance hole 14 and extends into the installation cavity 11, and cooperates with the body 10 to clamp the battery 30.

[0061] When the rear panel assembly 100 is in a normal use and installation state, the first side 12 is arranged away from the door body, and the second side 13 is arranged toward the door body.

[0062] In this embodiment, the fixing member 50 is disposed on the second side 13. In addition to clamping the battery 30, the fixing member 50 can also be further clamped between the door and the body 10. The elastic deformation of the fixing member 50 allows the body 10 and the door to fit more closely, thereby improving the stability and aesthetics of the rear panel assembly 100 when installed on the door.

[0063] Please refer to Figure 4 、 Figures 6 to 8 ,as well as Figure 10 In one embodiment of the present application, the fixing member 50 includes a main plate 51 and an abutting column 52. The main plate 51 is attached to the second side 13. The abutting column 52 is protruding from the side of the main plate 51 facing the first side 12. Part of the abutting column 52 passes through the hole 14 and extends into the installation cavity 11. The direction parallel to the direction from the first side 12 to the second side 13 is defined as the first direction. The abutting column 52 extending into the installation cavity 11 at least abuts against one side of the battery 30 in the second direction and cooperates with the body 10 to clamp the battery 30 in the second direction. The second direction intersects with the first direction.

[0064] In this embodiment, the fixing member 50 is configured to include a main plate 51 and abutment posts 52. This allows the relatively large main plate 51 to be attached to the second side 13 of the housing 10, thereby improving coverage of the second side 13 of the housing 10 and enhancing the tightness of the fit between the housing 10 and the door. The relatively small abutment posts 52 can be easily passed through the aperture 14 to cooperate with the housing 10 to clamp the battery 30. The main plate 51 and the housing 10 can be adhesively connected to improve the stability of the connection. Of course, the main plate 51 and the housing 10 can also be connected by screws to enhance the convenience of the connection. This application does not limit the connection method between the main plate 51 and the housing 10. Furthermore, the abutment posts 52 and the main plate 51 can be integrally formed to enhance the overall strength of the fixing member 50. This also allows the fixing member 50 to be manufactured in one piece, improving production efficiency. Furthermore, it should be noted that, in other embodiments, the abutting post 52 extending into the mounting cavity 11 may abut against one side of the battery 30 in the first direction, and cooperate with the housing 10 in the first direction to clamp the battery 30. Alternatively, the abutting post 52 extending into the mounting cavity 11 may abut against one side of the battery 30 in the first direction and one side of the battery 30 in the second direction, and cooperate with the housing 10 in both the first direction and the second direction to clamp the battery 30.

[0065] Please refer to Figure 4 ,as well as Figures 6 to 8 In one embodiment of the present application, the surface of the abutting column 52 for clamping the battery 30 is provided with an anti-slip structure 521, and the anti-slip structure 521 is a protrusion or a groove.

[0066] In this embodiment, the anti-slip structure 521 provided on the abutment column 52 can increase the friction between the abutment column 52 and the battery 30, thereby further improving the stability of the battery 30 clamping. Furthermore, by configuring the anti-slip structure 521 as a protrusion or groove, the anti-slip structure 521 can be formed directly on the abutment column 52, thereby improving the convenience of its processing and forming. Of course, in other embodiments, the surface of the abutment column 52 used to clamp the battery 30 can also be coated with an anti-slip coating to form the anti-slip structure 521. Alternatively, the surface of the abutment column 52 used to clamp the battery 30 can be embedded with a friction block to form the anti-slip structure 521. In addition, when the rear panel assembly 100 is in normal use and installation, when the abutment column 52 extending into the installation cavity 11 abuts at least one side of the battery 30 in the second direction, the anti-slip structure 521 can be provided on the upper and / or lower surfaces of the abutment column 52.

[0067] Please refer to Figure 4 ,as well as Figures 6 to 8 In one embodiment of the present application, a guide surface 522 is provided at one end of the abutting column 52 away from the main plate 51. The guide surface 522 is used to guide the battery 30 to be clamped between the body 10 and the abutting column 52. The guide surface 522 is an inclined surface or an arc surface.

[0068] In this embodiment, the guide surface 522 can guide the battery 30 to gradually fit between the abutment post 52 and the wall of the mounting cavity 11 opposite the abutment post 52, thereby achieving the abutment post 52 and the body 10 cooperating to clamp the battery 30. In this way, the alignment requirements of the battery 30 with the area formed between the abutment post 52 and the wall of the mounting cavity 11 can be reduced during installation, thereby facilitating easier installation of the battery 30.

[0069] Please refer to Figure 4 ,as well as Figures 6 to 8 In one embodiment of the present application, the fixing member 50 is provided with a material reduction hole 53, which extends along the first direction and passes through at least the two opposite sides of the main plate 51 in the first direction and the side of the abutment column 52 facing the main plate 51.

[0070] In this embodiment, the provision of the material reduction holes 53 can, on the one hand, improve the elastic deformation capacity of the fixing member 50, and on the other hand, can also make the wall thickness of the fixing member 50 relatively uniform, so as to improve the consistency of the molding at various locations and improve the molding effect of the fixing member 50. At the same time, such a provision can also reduce the manufacturing materials required for the fixing member 50, thereby helping to reduce manufacturing costs. Among them, the material reduction holes 53 can be provided near the surface of the abutment column 52 for clamping the battery 30. In addition, the material reduction holes 53 on the abutment column 52 can only penetrate the side of the abutment column 52 facing the main plate 51, and of course, can also further penetrate the side of the abutment column 52 facing away from the main plate 51.

[0071] Please refer to Figure 4 and Figure 10 In one embodiment of the present application, the number of the abutment columns 52 is at least two, wherein at least two abutment columns 52 are arranged side by side in a third direction and cooperate with the body 10 to clamp the battery 30, and the third direction intersects the first direction and the second direction.

[0072] In this embodiment, the provision of at least two abutment columns 52 allows each battery 30 to be clamped and limited by the cooperation of at least two abutment columns 52 and the body 10, thereby enriching the clamping positions of the battery 30 and further improving the stability of the installation of the battery 30.

[0073] Please refer to Figure 3 、 Figure 4 ,as well as Figures 6 to 8 In one embodiment of the present application, a partition plate 111 is provided in the installation cavity 11, and the partition plate 111 divides the installation cavity 11 into two sub-cavities 113 distributed sequentially in the second direction; the number of batteries 30 is at least two, and each battery 30 is arranged in a sub-cavity 113; the pass hole 14 is provided corresponding to the partition plate 111, and the end of the pass hole 14 away from the main plate 51 is connected to the two adjacent sub-cavities 113; the end of the abutment column 52 away from the main plate 51 extends into the two adjacent sub-cavities 113 on the back-to-back sides in the second direction, and cooperates with the body 10 to clamp the two batteries 30 in the second direction.

[0074] In this embodiment, by providing a clearance hole 14 at the position corresponding to the partition plate 111, the two adjacent sub-cavities 113 can be connected through the end of the clearance hole 14 away from the main plate 51, so as to achieve clamping and limiting of the two adjacent batteries 30. For example, when the panel assembly 100 is in normal use and installation, the upper side of the abutment column 52 can clamp and limit the upper battery 30 with the relative cavity wall in the upper sub-cavity 113, and the lower side of the abutment column 52 can clamp and limit the lower battery 30 with the relative cavity wall in the lower sub-cavity 113. This reduces the number of abutment columns 52 and clearance holes 14 required, which is conducive to simplifying the structure of the fixing member 50 and the body 10, and is conducive to improving the convenience of manufacturing. The provision of at least two batteries 30 can be used to adaptively power the electrical devices in the rear panel assembly 100. For example, a battery 30 with a relatively large capacity can be used to operate electrical components such as the display module and motor with a relatively large power in the door lock, while a battery 30 with a relatively small capacity can be used to operate electrical components such as the buttons with a relatively small power in the door lock. In this way, by using batteries 30 with different capacities to power electrical components of different powers, it is possible to better balance the endurance and environmental protection of the power supply to the electrical components. At the same time, when one of the batteries 30 is removed, the door lock can still be powered by the other batteries 30. In addition, it should be noted that the partition plate 111 can completely isolate the two sub-cavities 113 so that the two sub-cavities 113 are not connected, and of course it can also only separate a part so that the two sub-cavities 113 are connected.

[0075] Please refer to Figure 4 ,as well as Figures 6 to 8 In one embodiment of the present application, the fixing member 50 is provided with an insertion hole 54, which extends along the first direction and passes through at least one side of the abutment column 52 away from the main plate 51; the partition plate 111 is provided with a plug-in column 112 protruding from the inner side, and the plug-in column 112 is inserted into the insertion hole 54.

[0076] In this embodiment, the insertion and mating of the insertion post 112 and the insertion hole 54 facilitates positioning and limiting the installation of the fixing member 50 on the body 10, thereby improving the stability and accuracy of the installation of the fixing member 50 on the body 10. It also strengthens the abutment post 52, thereby improving the stability of the abutment post 52 in clamping and limiting the battery 30. Specifically, when the fixing member 50 is provided with the material reduction holes 53 described above, the insertion hole 54 can be located between the two material reduction holes 53 of the abutment post 52.

[0077] Please refer to Figures 1 to 8In one embodiment of the present application, the body 10 includes a main shell 15 and a first cover 16. The main shell 15 is provided with a mounting groove 151, and the notch of the mounting groove 151 faces the first side 12; the first cover 16 covers the notch of the mounting groove 151 and forms a mounting cavity 11 together with the mounting groove 151; the handle 70 is provided on the first side 12 of the main shell 15, the main plate 51 is provided on the second side 13 of the main shell 15, and the main shell 15 is provided with a through hole 14. The abutment column 52 extending into the mounting cavity 11 cooperates with the main shell 15 in the second direction to clamp the battery 30.

[0078] In this embodiment, the housing 10 is configured to include a main shell 15 and a first cover 16, allowing them to be manufactured independently and then assembled to enclose the mounting cavity 11. In this case, the separated main shell 15 and first cover 16 have a relatively simple structure, which facilitates the processing and forming of the mounting cavity 11. The main shell 15 can be extended in the second direction so that the handle 70 and the first cover 16 can be located at either end of the main shell 15 in the second direction, reducing the possibility of interference between the two. Furthermore, the first cover 16 can be detachably mounted to the main shell 15 to facilitate subsequent maintenance and replacement of the battery 30.
