[0048] A door lock is a kind of lock used by being installed on a door body. Among them, the door lock usually includes a front panel assembly, a rear panel assembly, and a lock body assembly located between the two, so as to realize that the lock body assembly can be controlled to be locked and unlocked through both the front panel assembly and the rear panel assembly.

[0049] However, in the related art, the handle, the rotating shaft, and the bearing in the rear panel assembly are connected in sequence, that is, the rotating shaft and the bearing are connected and fixed, and then the handle and the rotating shaft are connected and fixed. At this time, two connection structures are required to connect the rotating shaft and the bearing, and the rotating shaft and the handle respectively, so that the connection structure is relatively complex, resulting in the assembly of the rear panel assembly being relatively complex.

[0050] Therefore, based on the above considerations, in order to solve the problem that the assembly of the current rear panel assembly is relatively complex, the present application proposes a new rear panel assembly applied to a door lock. The rear panel assembly innovatively sets the handle and the rotating shaft to be clamped on the inner ring of the bearing in cooperation, so as to realize that connecting the handle and the rotating shaft can complete the connection of the handle, the bearing, and the rotating shaft at one time, simplify the connection structure between them, and improve the convenience of assembling the rear panel assembly. At the same time, a wear-resistant member is arranged in cooperation between the handle and the body to improve the stability of the installation support of the handle and reduce the wear between the handle and the wear-resistant member.

[0051] Next, the structure of the rear panel assembly proposed in the present application will be explained and described by way of embodiments. In an embodiment of the present application, please refer to Figures 1 to 3 , Figure 5 , Figure 8 and Figure 9 . The rear panel assembly 100 proposed in the present application includes a body 10, a bearing 20, a rotating shaft 30, a handle 40, and a wear-resistant member 50; the body 10 is provided with a mounting hole 11; the bearing 20 is installed in the mounting hole 11, and the bearing 20 includes a relatively rotatable inner ring 21 and an outer ring 23, and the outer ring 23 is connected to the body 10; the rotating shaft 30 passes through the inner ring 21; the handle 40 is connected to the rotating shaft 30 and is clamped on the inner ring 21 in cooperation with the rotating shaft 30; the wear-resistant member 50 is arranged between the handle 40 and the body 10.

[0052] The body 10 can be used to provide an installation position for installing and carrying the bearing 20, the rotating shaft 30, the handle 40, and other components in the rear panel assembly 100, such as a circuit board, a motor, or a communication module, etc., so as to facilitate the assembly of the various components 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 rectangular, and of course it can also be waist-shaped or oval, etc. The present application does not limit the shape of the body 10. Further, the mounting hole 11 provided on the body 10 can be a circular hole to improve the compactness and stability of the installation of the bearing 20. Among them, both ends of the mounting hole 11 can penetrate through the opposite sides of the body 10 and be exposed to the outside. Of course, the body 10 can also be further provided with a receiving cavity 13, one end of the mounting hole 11 communicates with the receiving cavity 13, and the other end penetrates through one side of the body 10 and is exposed to the outside. At this time, the end of the rotating shaft 30 away from the handle 40 can be received in the receiving cavity 13.

[0053] The bearing 20 can be installed in the mounting hole 11 and sleeved on the rotating shaft 30 to improve the smooth rotation of the rotating shaft 30. Among them, the fixing method of the outer ring 23 of the bearing 20 in the mounting hole 11 can be the interference fit setting through the mounting hole 11 as introduced below. Of course, the fixing method of the outer ring 23 of the bearing 20 in the mounting hole 11 can also be clamping and fixing through the cooperation of the clamping plate and the body 10. It can be seen that the present application does not limit the installation method of the bearing 20 in the mounting hole 11.

[0054] The rotating shaft 30 can be inserted through the inner ring 21 of the bearing 20. One end of it can be used to connect to the handle 40, and the other end can be used to drive the lock body assembly in the door lock to lock and unlock when the rotating shaft 30 rotates following the handle 40. In addition, the rotating shaft 30 can include a stop disc 33 as introduced below to abut and limit the end of the inner ring 21 of the bearing 20 away from the handle 40. Of course, it can also be that convex portions such as convex columns, convex blocks, or convex plates protrude on the side circumference of the rotating shaft 30 to abut and limit the end of the inner ring 21 of the bearing 20 away from the handle 40.

[0055] The handle 40 can be used to provide a gripping position for the user to conveniently grip and drive. At the same time, the handle 40 can also be used in cooperation with the rotating shaft 30 to clamp the inner ring 21, thereby realizing the limit of the rotating shaft 30 and the handle 40 in the axial direction of the rotation axis. Among them, the handle 40 can include a connecting section 41 and a gripping section 43. The connecting section 41 is connected to the rotating shaft 30 and extends along the axis direction of the rotating shaft 30. The connecting section 41 and the rotating shaft 30 cooperate to clamp the inner ring 21; the gripping section 43 is connected to the connecting section 41 and is arranged at an angle with the connecting section 41. At this time, the gripping section 43 at an angle with the axial direction of the rotating axis of the rotating shaft 30 can increase the torque to facilitate the user to drive the handle 40 to rotate. Of course, the present application is not limited to this. In other embodiments, the handle 40 may only include the connecting section 41. At this time, the user can grip the connecting section 41 to drive the handle 40 to rotate. In addition, the connection between the handle 40 and the rotating shaft 30 can be connected by a fastener 60 as described below. Of course, it can also be connected by snap connection or adhesive connection, etc. The present application does not limit the connection method between the handle 40 and the rotating shaft 30.

[0056] The wear-resistant member 50, as the name implies, is made of a material with good wear resistance, such as: polyoxymethylene, polyimide, polyether ether ketone or high manganese steel series, etc. The present application does not limit the specific material of the wear-resistant member 50. In addition, the wear-resistant member 50 can be an annular structure and surround the axial direction of the rotating shaft 30. Of course, the wear-resistant member 50 can also include a plurality of segments arranged in sequence around the axial direction of the rotating shaft 30. In addition, the wear-resistant member 50 can be clamped and fixed by the cooperation of the handle 40 and the body 10 as described below, or the wear-resistant member 50 can also be connected to one of the body 10 and the handle 40 by any connection method such as adhesive connection or snap connection. In addition, when the handle 40 includes the connecting section 41 and the gripping section 43 as described above, the wear-resistant member 50 can be arranged between the connecting section 41 and the body 10.

[0057] The rear panel assembly 100 of the technical solution of the present application is clamped in the inner ring 21 of the bearing 20 by the handle 40 and the rotating shaft 30, so that when the handle 40 and the rotating shaft 30 are connected, the connection and assembly of the handle 40, the rotating shaft 30 and the bearing 20 can be completed at the same time. At this time, there is no need to connect the handle 40, the rotating shaft 30 and the bearing 20 in sequence, etc., which can simplify the connection structure between them and simplify the assembly process, so as to improve the convenience of assembling the rear panel assembly 100. In addition, the rear panel assembly 100 in this solution is further provided with a wear-resistant part 50 between the handle 40 and the body 10, so that the wear between the handle 40 and the wear-resistant part 50 can be reduced while improving the stability of the installation support of the handle 40. That is, the possibility of shaking of the handle 40 is reduced, which is conducive to improving the feel of use, and also has a relatively long service life.

[0058] Please refer to Figure 3 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment of the present application, the handle 40 and the body 10 cooperate to clamp the wear-resistant part 50 .

[0059] In this embodiment, the wear-resistant part 50 is arranged to be clamped and fixed by the handle 40 and the body 10, so that there is no need to set a connection structure on the body 10 and / or the handle 40, and the wear-resistant part 50 can be limited when the handle 40 is assembled. In this way, the structure of the rear panel assembly 100 is further simplified, so as to further improve the convenience of assembling the rear panel assembly 100.

[0060] Please refer to Figures 3 to 5 ,as well as Figures 7 to 9 In one embodiment of the present application, the body 10 is provided with a positioning protrusion 15, which surrounds the mounting hole 11; the handle 40 is provided with a positioning step 45, which surrounds the axial direction of the rotating shaft 30, the positioning protrusion 15 is inserted into the positioning step 45, and the wear-resistant part 50 is arranged between the positioning protrusion 15 and the positioning step 45.

[0061] In this embodiment, the wear-resistant member 50 is disposed between the positioning protruding ring 15 and the positioning step 45, which can play a role in positioning and limiting the wear-resistant member 50, so as to improve the accuracy and stability of the installation of the wear-resistant member 50 and improve the stability of the installation of the handle 40 on the body 10. In addition, when the handle 40 includes the connecting section 41 and the gripping section 43 as described above, the positioning step 45 can be disposed on the connecting section 41.

[0062] Please refer to Figures 3 to 9In one embodiment of the present application, the positioning protruding ring 15 includes a first surface 151 and a second surface 153 connected to each other, and the first surface 151 is closer to the mounting hole 11 than the second surface 153; the positioning step 45 includes a first step surface 451 and a second step surface 453, and the first step surface 451 is closer to the mounting hole 11 than the second step surface 453; the wear-resistant part 50 includes a first annular plate 51 and a second annular plate 53 connected to each other, and the first annular plate 51 and the second annular plate 53 are both arranged around the axial direction of the rotating shaft 30 and at an angle; the first annular plate 51 is arranged between the first surface 151 and the first step surface 451, and the second annular plate 53 is arranged between the second surface 153 and the second step surface 453.

[0063] The first surface 151 may be located at the inner side of the positioning protruding ring 15 and disposed opposite to the first step surface 451 , and the second surface 153 may be disposed opposite to the second step surface 453 .

[0064] In this embodiment, the wear-resistant member 50 is configured to include a first annular plate 51 and a second annular plate 53, so that the contact area with the handle 40 and the body 10 can be increased, so as to improve the isolation effect of the wear-resistant member 50 on the handle 40 and the body 10. The first annular plate 51 and the second annular plate 53 are arranged at an angle, which can also be said that the second annular plate 53 surrounds one end of the first annular plate 51.

[0065] Please refer to Figures 3 to 6 In one embodiment of the present application, the positioning protrusion 15 is provided with a limiting groove 155, and the limiting groove 155 at least passes through the first surface 151 and the second surface 153; the wear-resistant part 50 also includes a limiting plate 55, which is connected to the first annular plate 51 and / or the second annular plate 53 and extends into the limiting groove 155.

[0066] In this embodiment, the cooperation between the limiting plate 55 and the limiting groove 155 can play a role in positioning and limiting the installation of the wear-resistant part 50, so as to further improve the accuracy and stability of the installation of the wear-resistant part 50. At the same time, the limiting plate 55 can also strengthen the strength of the fixing part to improve the service life of the fixing part. Among them, the number of the limiting groove 155 and the limiting plate 55 can be one, and of course, it can also be two or more, and they are spaced around the axial direction of the rotating shaft 30. In addition, the limiting groove 155 can only penetrate the first surface 151 and the second surface 153, or it can further penetrate the side of the positioning convex ring 15 away from the first surface 151, and / or the side away from the second surface 153. In addition, the limiting plate 55, the first annular plate 51 and the second annular plate 53 can be an integral structure to further enhance the strength of the fixing part, and at the same time, it can be manufactured by integral molding to improve the production efficiency of the fixing part.

[0067] In an embodiment of the present application, the wear-resistant member 50 is made of plastic, and the rear panel assembly 100 further includes a metal gasket disposed between the wear-resistant member 50 and the handle 40.

[0068] In this embodiment, setting the wear-resistant member 50 to be plastic can reduce the manufacturing cost of the wear-resistant member 50, and at the same time is beneficial to improving the compactness of the installation between the handle 40 and the body 10. Further, a metal gasket is stacked on the metal gasket, which can reduce the friction force and improve the smoothness of the rotation of the handle 40. At the same time, the overall strength and stability of the rear panel assembly 100 are improved.

[0069] In an embodiment of the present application, the outer ring 23 and the mounting hole 11 are in interference fit.

[0070] In this embodiment, setting the outer ring 23 and the mounting hole 11 to be in interference fit, on the one hand, eliminates the need to additionally provide a connection structure on the body 10 to limit the outer ring 23, which is beneficial to further simplifying the structure of the rear panel assembly 100 and improving the manufacturing convenience. On the other hand, it can also achieve the stable installation of the bearing 20 on the body 10.

[0071] Please refer to Figure 3 and Figure 4 and Figure 8 and Figure 9 In an embodiment of the present application, the mounting hole 11 includes a first hole section 111 and a second hole section 113. The second hole section 113 communicates with the first hole section 111, and the cross-sectional area of the second hole section 113 is smaller than the cross-sectional area of the first hole section 111; the outer ring 23 and the first hole section 111 are in interference fit, and a part of the handle 40 extends into the second hole section 113 and is clamped with the inner ring 21 in cooperation with the rotating shaft 30.

[0072] In this embodiment, setting the mounting hole 11 to include the first hole section 111 and the second hole section 113 with different cross-sectional areas enables the bearing 20 to be abutted and positioned at the connection between the first hole section 111 and the second hole section when installed in the first hole section 111, which is beneficial to improving the installation accuracy of the bearing 20 on the body 10. In addition, with this setting, the area of the opening at the end of the mounting hole 11 close to the handle 40 is relatively small, so that the volumes of the wear-resistant member 50 and the handle 40 can also be correspondingly set relatively small to reduce the overall volume of the rear panel assembly 100. In addition, when the handle 40 includes a connecting section 41 and a holding section 43 as described above, a part of the connecting section 41 extends into the second hole section 113.

[0073] Please refer to Figure 3 and Figure 5 and Figure 8 and Figure 9, in an embodiment of the present application, the rotating shaft 30 includes a shaft body 31 and a stop disc 33. The rotating shaft 30 passes through the inner ring 21; the stop disc 33 is sleeved on the rotating shaft 30, and the handle 40 is connected to the shaft body 31 and cooperates with the stop disc 33 to clamp the inner ring 21.

[0074] In this embodiment, the rotating shaft 30 is set to include a shaft body 31 and a stop disc 33, so that the stop disc 33 can have a relatively large contact area with the inner ring 21 of the bearing 20, which is beneficial to improving the connection stability among the rotating shaft 30, the bearing 20 and the handle 40.

[0075] Please refer to Figure 5 , and Figures 7 to 9 , in an embodiment of the present application, the handle 40 is provided with a plug hole 47, and one end of the shaft body 31 is inserted into the plug hole 47; the shaft body 31 is provided with a through hole 311, and the through hole 311 extends along the axial direction of the shaft body 31 and penetrates through the end of the shaft body 31 away from the handle 40; the rear panel assembly 100 further includes a fastener 60, the fastener 60 is arranged in the through hole 311, and the fastener 60 passes through the shaft body 31 and is inserted into the handle 40 to detachably connect the handle 40 and the shaft body 31.

[0076] In this embodiment, inserting the shaft body 31 of the rotating shaft 30 into the plug hole 47 of the handle 40 can improve the compactness of the distribution of the rotating shaft 30 and the handle 40. At the same time, it can also play a role in positioning and limiting the installation of the rotating shaft 30 and the handle 40, so as to improve the accuracy and stability of their connection. The arrangement of the through hole 311 and the fastener 60 enables the connection structure between the handle 40 and the rotating shaft 30 to be hidden, so as to play an anti-disassembly role and reduce the possibility of damage to the connection structure at this place, while improving the appearance beauty of the rear panel assembly 100. Among them, the fastener 60 can be a screw, so as to simplify the assembly process of the two on the basis of realizing the detachable connection between the handle 40 and the rotating shaft 30. In addition, when the handle 40 includes a connecting section 41 and a holding section 43 as introduced above, the plug hole 47 can be only arranged on the connecting section 41, or of course, part can be arranged on the connecting section 41 and part can be arranged on the holding section 43. Similarly, after passing through the shaft body 31, the fastener 60 can be inserted and connected to the connecting section 41, or can be inserted and connected to the holding section 43.
