Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0049] A door lock is a kind of lock used by being installed on a door body. Among them, a door lock generally includes a front panel assembly, a rear panel assembly, and a lock body assembly located between the two, so as to realize that both the front panel assembly and the rear panel assembly can control the lock body assembly to lock and unlock.

[0050] Among them, in the related art, a control board and a key are respectively arranged on the body and the handle of the rear panel assembly, and the two are electrically connected through an electrical connection wire. At this time, since the handle needs to rotate during work, the electrical connection wire will be pulled and worn at the connection between the body and the handle and damaged, resulting in affecting the normal operation of the rear panel assembly.

[0051] Therefore, based on the above considerations, in order to solve the problem that the electrical connection wire of the current rear panel assembly is easily damaged, this application proposes a new rear panel assembly applied to a door lock. The rear panel assembly is innovatively provided with a wire bundling member made of an elastically deformable material, so as to limit and make elastic contact with the electrical connection wire at the connection between the handle assembly and the body through the wire bundling hole of the wire bundling member, avoiding hard contact friction and causing the electrical connection wire to be easily damaged, so as to ensure the normal and stable operation of the rear panel assembly.

[0052] Next, the structure of the rear panel assembly proposed in this application will be explained and illustrated with embodiments. In an embodiment of this application, please refer to Figures 1 to 4, the rear panel assembly 100 proposed in this application includes a body 10, a handle assembly 20, a wire bundling member 30, and an electrical connection wire 40; the body 10 is provided with a first electrical component 11; the handle assembly 20 is rotatably arranged on the body 10 and is provided with a second electrical component 242 and a wire passing channel 211; the wire bundling member 30 is arranged on the handle assembly 20 and is provided with a wire bundling hole 311, the wire bundling hole 311 communicates with one end of the wire passing channel 211 away from the second electrical component 242, and the material of the wire bundling member 30 is an elastically deformable material; one end of the electrical connection wire 40 is electrically connected to the first electrical component 11, the other end is electrically connected to the second electrical component 242, and is arranged in the wire passing channel 211 and the wire bundling hole 311.

[0053] The body 10 can be used to provide an installation position for installing and carrying the handle assembly 20 and other components in the rear panel assembly 100, such as a motor or a communication module, etc., so as to facilitate the assembly of each component in the rear panel assembly 100 to form a whole for use. Among them, when the rear panel assembly 100 is in the normal use and installation state, the projection of the body 10 in the vertical plane can be a rectangle, and of course it can also be a kidney shape or an oval shape, etc. This application does not limit the shape of the body 10. Further, the first electrical component 11 provided on the body 10 can be a control board. Of course, the first electrical component 11 can also be a motor or other electrical components. It can be seen that this application does not limit the specific type of the first electrical component 11. In addition, the first electrical component 11 can be arranged inside the body 10 to improve the isolation and protection effect on the first electrical component 11, and at the same time improve the aesthetics of the appearance of the rear panel assembly 100. At this time, the body 10 can be provided with an installation cavity 12, and the first electrical component 11 can be arranged in the installation cavity 12. At the same time, the body 10 can also be provided with an installation hole 13 communicating with the installation cavity 12, the handle assembly 20 can be rotatably inserted into the installation hole 13, and the wire bundling member 30 can be located in the installation cavity 12. Of course, in other embodiments, it is also possible to directly arrange the first electrical component 11 outside the body 10.

[0054] The handle assembly 20 can be used to provide a gripping position for a user to rotate, and can drive the lock body assembly in the door lock to lock and unlock when rotating. Among them, in order to improve the convenience of manufacturing the handle assembly 20, the handle assembly 20 can be set to include a rotating shaft 21 and a handle 24, so as to split the handle assembly 20 into two relatively simple parts for separate independent manufacturing, and then assembled into a whole. At this time, the rotating shaft 21 can be rotatably inserted into the mounting hole 13 of the machine body 10, and is provided with a wire passing channel 211. The wire bundling member 30 can be arranged at one end of the rotating shaft 21; and the handle 24 can be connected to the other end of the rotating shaft 21, and is provided with a receiving cavity 241 communicating with the wire passing channel 211. The second electrical contact device 242 can be arranged in the receiving cavity 241. Among them, the wire passing channel 211 can be arranged to extend along the rotation axis direction of the handle assembly 20, so that the shape of the wire passing channel 211 is relatively regular and the convenience of processing it is improved. Moreover, the wire passing channel 211 can also penetrate the side peripheral surface of the rotating shaft 21 to further improve the convenience of processing the wire passing channel 211. At this time, the handle 24 can be sleeved on the outside of the rotating shaft 21 to cover the wire passing channel 211. In addition, the second electrical contact device 242 arranged on the handle 24 can be a button, and of course can also be a microphone module or other electrical contact devices. It can be seen that the specific type of the second electrical contact device 242 in this application is not limited either.

[0055] The wire bundling member 30 can limit the electric connection wire 40 at the connection between the handle assembly 20 and the body 10 through the wire bundling hole 311, so that the electric connection wire 40 at this place can stably rotate with respect to the handle assembly 20. Among them, the central line direction of the wire bundling hole 311 can intersect with the extension direction of the wire passing channel 211, so that the first electrical component 11 and one end of the electric connection wire 40 close to the first electrical component 11 can be arranged in a way that intersects with the rotation axis of the handle assembly 20, thereby avoiding an excessive length dimension of the rear panel assembly 100 in the rotation axis direction of the handle assembly 20. For example, when the rear panel assembly 100 is in the normal use and installation state, the rotation axis of the handle assembly 20 and the wire passing channel 211 can be arranged to extend along a horizontal direction, and the wire passing hole can be arranged to extend along a vertical direction. In addition, the wire bundling member 30 can be a seat body structure, and of course, it can also be a cylindrical structure or a columnar structure, etc. The present application does not limit the structural type and shape of the wire bundling member 30. In addition, the material of the wire bundling member 30 is an elastically deformable material, that is, it can be reset after deformation. Among them, the material of the wire bundling member 30 can be silicone, so that the wire bundling member 30 can have good elasticity to adapt to abut and limit the electric connection wire 40 through elastic deformation, and can also have a certain strength to improve the abut and limit stability of the wire bundling member 30. Of course, the present application is not limited to this. In other embodiments, the material of the wire bundling member 30 can also be rubber or other materials that can undergo elastic deformation.

[0056] The electric connection wire 40 can be used to electrically connect the first electrical component 11 on the body 10 and the second electrical component 242 on the handle 24, so that the second electrical component 242 can receive the signal input by the first electrical component 11.

[0057] In the rear panel assembly 100 of the technical solution of the present application, by arranging the wire bundling member 30 on the handle assembly 20, the electric connection wire 40 can be limited through the wire bundling hole 311 of the wire bundling member 30 at the connection between the handle assembly 20 and the body 10, improving the stability of the arrangement of the electric connection wire 40. And because the material of the wire bundling member 30 is still an elastically deformable material, there will be no hard contact friction between the wire bundling member 30 and the electric connection wire 40. Therefore, during the rotation of the handle assembly 20, the possibility of pulling and wearing the electric connection wire 40 and causing damage can be reduced, so that the rear panel assembly 100 can work normally and stably, thereby improving the working stability of the rear panel assembly 100.

[0058] In an embodiment of the present application, the wire bundling member 30 is provided with a partition hole 314, and the partition hole 314 penetrates the inner and outer sides of the wire bundling hole 311, so that the wire bundling hole 311 is not closed in its circumferential direction.

[0059] In this embodiment, the arrangement of the partition holes 314 causes the wire bundling holes 311 not to be closed in their circumferential directions. In other words, it enables the wire bundling member 30 to form a notch at this position. At this time, on the one hand, it is realized that the electrical connection line 40 can be snapped into the wire bundling holes 311 from the partition holes 314, so as to improve the convenience of arranging the electrical connection line 40 on the wire bundling member 30. On the other hand, it can also enhance the elastic deformation ability of the wire bundling member 30 to improve the clamping effect on the electrical connection member, and further improve the stability of the arrangement of the electrical connection line 40 on the wire bundling member 30.

[0060] Please refer to Figures 5 to 7 , in an embodiment of the present application, the rear panel assembly 100 further includes a fastener 50, and the fastener 50 is connected to the handle assembly 20 and cooperates with the handle assembly 20 to clamp the wire bundling member 30.

[0061] In this embodiment, since both the fastener 50 and the handle assembly 20 are rigid structures, they can be connected relatively firmly, so as to improve the stability of the installation of the wire bundling member 30 on the handle assembly 20 and improve the stability of the arrangement of the electrical connection line 40. At the same time, it also makes it unnecessary to provide a connection structure on the wire bundling member 30, which is conducive to simplifying the structure of the wire bundling member 30 and protecting the structural strength of the wire bundling member 30 itself. Among them, when the handle assembly 20 includes a rotating shaft 21 and a handle 24 as introduced above, the fastener 50 can be connected to the rotating shaft 21. In addition, the fastener 50 and the handle assembly 20 can be in threaded connection, and of course, they can also be in snap connection, etc. The present application does not limit this. In addition, in other embodiments, the wire bundling member 30 can also be directly connected to the handle assembly 20 by connection means such as bonding.

[0062] Please refer to Figures 5 to 7 , in an embodiment of the present application, the handle assembly 20 is provided with a connection hole 214, and the fastener 50 is in threaded connection with the connection hole 214, and the center line direction of the connection hole 214 intersects with the center line direction of the wire bundling holes 311.

[0063] In this embodiment, the fastener 50 can be a screw and is arranged to be threadedly connected to the connection hole 214, which can simplify the connection between the fastener 50 and the handle assembly 20 and enable detachable maintenance of the wire bundling member 30. Additionally, since the central line directions of the connection hole 214 and the wire bundling hole 311 intersect, it is also possible to adjust the clamping force of the wire bundling member 30 on the electrical connection wire 40 by adjusting the tightening degree of the fastener 50. Among them, when the handle assembly 20 includes a rotating shaft 21 and a handle 24 as introduced above, the connection hole 214 can be provided on the rotating shaft 21. Additionally, the fastener 50 can directly cooperate with the handle assembly 20 to clamp the wire bundling member 30. Of course, it is also possible to provide a backing plate 51 between the wire bundling member 30 and the fastener 50. At this time, the fastener 50 can pass through the backing plate 51 and be connected to the connection hole 214 to press the wire bundling member 30 through the backing plate 51 with a relatively large area. Furthermore, the number of connection holes 214 can be set to two and distributed on opposite sides of the wire bundling member 30, so as to improve the installation stability of the wire bundling member 30 by having the two fasteners 50 exert a pressing effect on the wire bundling member 30 on both opposite sides of the wire bundling member 30.

[0064] Please refer to Figures 7 to 11 , in an embodiment of the present application, the handle assembly 20 is provided with an installation groove 215, and the installation groove 215 communicates with one end of the wire passing channel 211 away from the second electrical component 242, and the wire bundling member 30 is arranged in the installation groove 215.

[0065] In this embodiment, the installation groove 215 can play a role in positioning and limiting the installation of the wire bundling member 30, which is beneficial to improving the accuracy and stability of the installation of the wire bundling member 30 on the handle assembly 20. Among them, the notch of the installation groove 215 can face one side in the direction of the rotation axis of the handle assembly 20, and of course, it can also face one side in the direction of the center line of the wire passing hole 311. In addition, when the handle assembly 20 includes a rotating shaft 21 and a handle 24 as introduced above, the installation groove 215 can be arranged on the rotating shaft 21. Moreover, in order to provide a setting position for arranging the installation groove 215, the rotating shaft 21 can further include a shaft body 212 and a disc portion 213. The shaft body 212 can be rotatably inserted into the installation hole 13 of the machine body 10, and the disc portion 213 can be sleeved on the part of the shaft body 212 extending into the installation cavity 12 of the machine body 10. The handle 24 can be connected to one end of the shaft body 212 located outside the machine body 10. At this time, the wire passing channel 211 can be partially arranged on the shaft body 212 and partially arranged on the disc portion 213, and of course, it can also be entirely arranged on the shaft body 212; while the installation groove 215 and the connection hole 214 introduced above can be arranged on the disc portion 213 and located on the side of the disc portion 213 away from the handle 24. Further, in order to improve the convenience of assembling the rear panel assembly 100, the rear panel assembly 100 can further include a bearing 60. The outer ring of the bearing 60 can be arranged in an interference fit with the installation hole 13, and the disc portion 213 and the handle 24 can cooperate to clamp the inner ring of the bearing 60.

[0066] Please refer to Figure 7 and Figures 10 to 13 In an embodiment of the present application, the wire passing channel 211 extends along the rotation axis direction of the handle assembly 20, and the notch of the installation groove 215 faces away from the second electrical component 242 in the extension direction of the wire passing channel 211; the center line direction of the wire passing hole 311 intersects with the extension direction of the wire passing channel 211. The wire passing hole 311 includes opposite first hole openings 312 and second hole openings 313. The first hole opening 312 is closer to the wire passing channel 211 than the second hole opening 313; the groove wall of the installation groove 215 includes a first groove wall 216, and the first groove wall 216 is relatively spaced from the first hole opening 312.

[0067] In this embodiment, the notch of the installation groove 215 is set to face the side of the disk portion 213 of the rotating shaft 21 away from the handle 24, so that the depth of the installation groove 215 can be relatively shallow, which is beneficial to improving the convenience of machining the installation groove 215. At the same time, it is also convenient to directly place the side of the disk portion 213 of the rotating shaft 21 away from the handle 24 into the installation groove 215 for installation. Further, the central line direction of the wire bundling hole 311 and the extending direction of the wire passing channel 211 are set to intersect, so that, as introduced above, the first electrical component 11 and one end of the electrical connection line 40 close to the first electrical component 11 can be arranged to extend in a manner intersecting with the rotation axis of the handle assembly 20, improving the compactness of the distribution among the various components in the rear panel assembly 100. Further, the first groove wall 216 of the installation groove 215 and the first orifice 312 of the wire bundling hole 311 are arranged at a relative interval, so that the first orifice 312 will not be blocked by the groove wall of the installation groove 215, facilitating the smooth entry of the electrical connection line 40 into the wire passing channel 211 after extending out from the first orifice 312.

[0068] Please refer to Figure 7 , and Figures 10 to 13 , in an embodiment of the present application, the wire bundling member 30 includes a main body portion 31 and an abutting portion 33. The main body portion 31 is provided with a wire bundling hole 311; the abutting portion 33 is connected to the side of the main body portion 31 where the first orifice 312 is formed and abuts against the first groove wall 216.

[0069] In this embodiment, the wire bundling member 30 is set to include a main body portion 31 and an abutting portion 33, and the abutting portion 33 abuts against the first groove wall 216. In this way, on the basis of realizing the relative interval between the first orifice 312 and the first groove wall 216, the wire bundling member 30 still has an abutting relationship with the first groove wall 216 through the abutting portion 33, so that the first groove wall 216 plays a positioning and limiting role for the wire bundling member 30 during installation. Among them, in order to improve the uniformity and stability of abutting, the number of the abutting portions 33 can be two and are distributed on opposite sides of the first orifice 312. In addition, the main body portion 31 can be a seat structure, and the abutting portion 33 can be a block structure.

[0070] Please refer to Figures 8 to 12 , in an embodiment of the present application, the groove wall of the installation groove 215 further includes a second groove wall 217. The second groove wall 217 corresponds to the notch of the installation groove 215, and the second groove wall 217 is provided with a positioning hole 217a; the wire bundling member 30 further includes a positioning portion 35. The positioning portion 35 is connected to the main body portion 31 and / or the abutting portion 33 and is inserted into the positioning hole 217a.
