[0042] Referring to Figures 1 and 2, the present application provides a handle structure 100. Figure 1 is a three-dimensional view of a handle structure 100 of an embodiment of the present application, and Figure 2 is an exploded schematic diagram of the handle structure 100 shown in Figure 1. The handle structure 100 is applied to a door lock. The handle structure 100 cooperates with the lock core of the door lock and can control the lock core to unlock, thereby realizing interaction with the door. Of course, in other embodiments of the present application, the handle structure 100 can also be applied to other occasions where a handle 110 is required to unlock the door lock, such as a cabinet, a control cabinet, etc. The present application only illustrates the application of the handle structure 100 to a door lock as an example. Furthermore, the door lock is a smart door lock.

[0043] It is understandable that the handle structure is usually a front disassembly structure, which usually includes a handle and an identification module, and the identification module is fixed to the handle through a shaft sleeve and other components, but this will increase the number of parts of the handle structure, increase costs, and complicate the structure and process, which is not convenient for assembly and use. To this end, the present application provides a new handle structure 100, which can reduce the number of parts, has a simple and reliable structure, simplifies the assembly process, facilitates assembly, and reduces costs from the production process. At the same time, it can also ensure that the installation position of the parts is accurate, so as to accurately identify the user's fingerprint and facilitate user use. The specific structure of the handle structure 100 of an embodiment is introduced below.

[0044] Referring to FIGS. 1 to 6 , in one embodiment, the handle structure 100 includes a handle 110, a fingerprint module 120, and a fastener 130. The handle 110 is provided with a through-hole 111, and the inner wall of the through-hole 111 is provided with an internal thread (not shown). The fingerprint module 120 is disposed in the through-hole 111. The fastener 130 includes a main body section 131 and an external thread (not shown), the external thread is disposed on the outer wall of the main body section 131, and the fastener 130 is installed in the through-hole 111 through the cooperation of the external thread and the internal thread, and presses the fingerprint module 120 to fix the fingerprint module 120 to the end of the through-hole 111. FIG. 3 is a top view of the handle structure 100 shown in FIG. 1 , FIG. 4 is a cross-sectional view of the handle structure 100 shown in FIG. 3 at AA, FIG. 5 is a front view of the handle structure 100 shown in FIG. 3 , and FIG. 6 is a cross-sectional view of the handle structure 100 shown in FIG. 5 at BB.

[0045] The handle 110 is the outer shell of the handle structure 100, and the handle 110 is installed on the door lock. The handle 110 has a through-mounted mounting hole 111, and the fingerprint module 120 is arranged in the mounting hole 111, and the fingerprint module 120 is exposed from the mounting hole 111. The fingerprint module 120 is used to identify fingerprints, and the door lock has a lock core, and the fingerprint module 120 is electrically connected to the lock core. When the user holds the handle 110, the user's thumb or other fingers can press the fingerprint module 120, and the fingerprint module 120 can identify whether the user's fingerprint is correct. If the user's fingerprint is correct, the fingerprint module 120 sends an unlocking signal to the lock core to control the lock core to unlock. At this time, the user can drive the door to open by operating the handle 110. If the user's fingerprint is incorrect, the fingerprint module 120 will not send an unlocking signal to the lock core, and the lock core remains locked.

[0046] Typically, the fingerprint module 120 is located at the end of the mounting through hole 111, and the fingerprint module 120 is located at the end of the mounting through hole 111 away from the door, that is, the fingerprint module 120 is located at the end of the mounting through hole 111 facing the user. This makes it convenient for the user to use the fingerprint module 120. In order to ensure that the fingerprint module 120 can be reliably fixed to one end of the mounting through hole 111, the present application sets a fastener 130 in the mounting through hole 111. The fastener 130 includes an external thread, and the inner wall of the mounting through hole 111 has an internal thread. When the fastener 130 is installed in the mounting through hole 111, the fastener 130 is fixed to the mounting through hole 111 by screwing the external thread and the internal thread. In addition, when the fastener 130 is installed in the mounting through hole 111, the end of the fastener 130 can press against the fingerprint module 120, so that the fingerprint module 120 is reliably located at one end of the mounting through hole 111.

[0047] As shown in FIG. 2 , FIG. 4 and FIG. 6 , specifically, the fastener 130 further includes a main body section 131, and an external thread is provided on the outer wall of the main body section 131. When the fastener 130 is installed in the installation through hole 111, the main body section 131 is aligned with the installation through hole 111, and the external thread and the internal thread are provided correspondingly. During installation, the external thread and the internal thread are gradually screwed together, and the main body section 131 is gradually screwed into the installation through hole 111. When the external thread and the internal thread are in place, the end of the fastener 130 presses against the fingerprint module 120 to achieve the assembly of the handle structure 100.

[0048] In the handle structure 100 of the above embodiment, the fastener 130 is screwed with the internal thread of the mounting through hole 111 through the external thread, so that the fastener 130 directly presses the fingerprint module 120, thereby better fixing the fingerprint module 120 in the mounting through hole 111 of the handle 110. In this way, the number of parts can be reduced, the structure is simple and reliable, and the assembly process is simplified, which is convenient for assembly and reduces the cost from the production process. At the same time, it can also reduce the impact of assembly on the installation position of the fingerprint module 120, ensure that the installation position of the fingerprint module 120 is accurate, so that the user's fingerprint can be accurately identified and it is easy to use.

[0049] Optionally, the handle 110 includes a handle 112 and a mounting portion 113, the mounting portion 113 has a through mounting through hole 111, and the handle 112 is arranged on one side of the mounting portion 113. After the fingerprint module 120 unlocks the lock cylinder, the user can open the door by operating the handle 112. Optionally, the handle 112 and the mounting portion 113 are an integrated structure to ensure the reliability of the handle structure 100. Of course, in other embodiments of the present application, the handle 112 and the mounting portion 113 can also be separately arranged and reliably fixed by gluing, screwing, etc. Optionally, the mounting portion 113 is arranged in a cylindrical shape. Of course, in other embodiments of the present application, the mounting portion 113 can also be prismatic or other shapes.

[0050] Optionally, the handle 110 is further provided with a limiting edge 114, which is provided at the edge of the mounting through hole 111 and extends toward the inner side of the mounting through hole 111. In other words, the limiting edge 114 can form a closed structure at the end of the mounting through hole 111. After the fingerprint module 120 is installed in the mounting through hole 111, the fingerprint module 120 contacts the limiting edge 114, and the fingerprint module 120 is limited by the limiting edge 114 to prevent the fingerprint module 120 from protruding from the mounting through hole 111.

[0051] Referring to FIG. 2 , FIG. 4 and FIG. 6 , in one embodiment, the fastener 130 further includes a contact section 132, which is disposed at one end of the main body section 131 and is used to press the fingerprint module 120 to fix the fingerprint module 120 in the mounting through hole 111. The contact section 132 is located at one end of the main body section 131 facing the fingerprint module 120, and the main body section 131 contacts the fingerprint module 120 through the contact section 132 and presses the fingerprint module 120.

[0052] An abutment section 132 is provided at one end of the main section 131, and the outer wall of the abutment section 132 is not provided with an external thread, and the fastener 130 is fixed to the mounting through hole 111 through the external thread of the outer wall of the main section 131. In this way, the length of the external thread along the axial direction of the fastener 130 can be reduced, which facilitates the fastening connection between the fastener 130 and the mounting through hole 111. When the fastener 130 is installed, the abutment section 132 is placed in the first mounting hole, and then the main section 131 is screwed and fixed to the mounting through hole 111 through the cooperation of the external thread and the internal thread. During the process of screwing and connecting the main section 131 and the mounting through hole 111, the abutment section 132 gradually contacts the fingerprint module 120, and finally presses the fingerprint module 120 to fix the fingerprint module 120.

[0053] Referring to Fig. 2, Fig. 4 and Fig. 6, in one embodiment, the fastener 130 further includes an operating section 133, which is disposed at one end of the main section 131 away from the abutting section 132. The operating section 133 is disposed at the other end of the main section 131, that is, the operating section 133 and the abutting section 132 are disposed at both ends of the main section 131, and the operating section 133 is a part for the user to operate. The user can tighten or loosen the external thread and the internal thread of the outer wall of the main section 131 through the operating section 133, thereby realizing the tightening or loosening operation of the fastener 130.

[0054] Optionally, the main body section 131, the operating section 133 and the abutting section 132 are an integrated structure. In this way, the fastener 130 can be easily processed and formed, and the structural strength of the fastener 130 can be ensured to prevent the fastener 130 from breaking during use. At the same time, the assembly process of the fastener 130 can be simplified and easy to use.

[0055] 2, 4 and 6, in one embodiment, the diameter of the main body section 131 is smaller than the diameter of the operating section 133 and larger than the diameter of the abutting section 132. In other words, the diameters of the operating section 133, the main body section 131 and the abutting section 132 decrease in sequence along the axial direction of the fastener 130.

[0056] When the diameter of the main body section 131 is larger than the diameter of the abutting section 132, it is easy to install the abutting section 132 in the installation through hole 111, and avoid the abutting section 132 from contacting the internal thread of the installation through hole 111. At the same time, when the diameter of the main body section 131 is smaller than the diameter of the operating section 133, the operating section 133 can achieve the limited installation of the fastener 130, and avoid the fastener 130 from excessively screwing the external thread and the internal thread and then excessively pressing the fingerprint module 120.

[0057] Optionally, the inner wall of the mounting through hole 111 has a limiting step 115, and the operating section 133 can abut against the limiting step 115 to limit the movement of the fastener 130 toward the fingerprint module 120. The fastener 130 is screwed and installed in the mounting through hole 111 by the cooperation of the external thread and the internal thread. When the operating section 133 abuts against the limiting step 115, the external thread of the fastener 130 cannot continue to be screwed with the internal thread of the mounting through hole 111, thereby limiting the movement of the fastener 130 toward the fingerprint module 120, preventing the fastener 130 from excessively pressing the fingerprint module 120, and ensuring the performance of the fingerprint module 120.

[0058] 5 to 10 , in one embodiment, the handle 110 includes a plurality of fixing protrusions 116, which are arranged at intervals along the circumference of the mounting through hole 111 on the inner wall of the mounting through hole 111, and the surfaces of the fixing protrusions 116 have internal threads, and the fixing protrusions 116 are fixed to the fastener 130 by the cooperation of the internal threads and the external threads. FIG7 is a cross-sectional view of the handle structure 100 shown in FIG5 at CC, FIG8 is a partial cross-sectional view of the handle 110 in the handle structure 100 shown in FIG5 , FIG9 is a schematic diagram of the handle 110 in the handle structure 100 shown in FIG2 viewed from one angle, and FIG10 is a schematic diagram of the handle 110 shown in FIG9 viewed from another angle.

[0059] The fixing protrusion 116 is protrudingly arranged on the inner wall of the mounting through hole 111, and a plurality of fixing protrusions 116 are evenly distributed in the mounting through hole 111, and there is a spacing between adjacent fixing protrusions 116 to form a mounting channel 117, and the fingerprint module 120 is mounted on the end of the mounting through hole 111 through the mounting channel 117. The fixing protrusion 116 is located on the inner wall of the middle area of ​​the axial direction of the mounting through hole 111, and the surface of the fixing protrusion 116 is provided with an internal thread. After the fastener 130 is installed in the mounting through hole 111, the external thread of the outer wall of the main section 131 is screwed and connected with the internal thread on the plurality of fixing protrusions 116.

[0060] That is to say, the fixing protrusion 116 can meet the installation requirements of the fingerprint module 120. At the same time, the surface of the fixing protrusion 116 can also be provided with an internal thread to be screwed together with the external thread of the main section 131. In one embodiment, the axial length of the fixing protrusion 116 is greater than or equal to the axial length of the main section 131. In this way, the length of the screwing connection between the external thread and the internal thread can be guaranteed, and then the connection length between the fastener 130 and the mounting through hole 111 can be guaranteed, so as to ensure that the fastener 130 is reliably fixed in the mounting through hole 111.

[0061] 2, 10 to 12, in one embodiment, the fingerprint module 120 is provided with a positioning protrusion 121, and the inner wall of the mounting through hole 111 is provided with a positioning groove 118, and the positioning protrusion 121 cooperates with the positioning groove 118 to guide and position the fingerprint module 120. FIG11 is a schematic diagram of the fingerprint module 120 in the handle structure 100 shown in FIG2, and FIG12 is an exploded view of the fingerprint module 120 shown in FIG11.

[0062] The positioning protrusion 121 is arranged on the outer peripheral surface of the fingerprint module 120 and protrudes from the outer peripheral surface of the fingerprint module 120. The inner wall of the mounting through hole 111 has a positioning groove 118 corresponding to the positioning protrusion 121. One end of the positioning groove 118 is flush with the end of the mounting through hole 111 close to the door body, and the positioning protrusion 121 of the fingerprint module 120 passes through the positioning groove 118 and is installed to one end of the mounting through hole 111.

[0063] When installing the fingerprint module 120, the positioning protrusion 121 is aligned with the positioning groove 118. The cooperation between the positioning protrusion 121 and the positioning groove 118 can play a guiding and positioning role, so that the fingerprint module 120 is installed to the predetermined position in the installation through hole 111 through the guiding cooperation between the positioning protrusion 121 and the positioning groove 118, thereby realizing the accurate assembly of the fingerprint module 120.

[0064] Optionally, the positioning groove 118 is arranged corresponding to the installation channel 117 formed by two adjacent fixing protrusions 116. In this way, the positioning protrusion 121 of the fingerprint module 120 can be installed at a predetermined position after passing through the positioning groove 118 and the installation channel 117 to ensure that the fingerprint module 120 is installed at an accurate position.

[0065] Referring to Figures 4, 11 and 12, in one embodiment, the fingerprint module 120 includes a fingerprint head 122, a support member 123 and a connecting line 124. The support member 123 is arranged on the side of the fingerprint head 122 facing the fastener 130. One end of the connecting line 124 is connected to the fingerprint head 122, and the other end extends through the support member 123. The fastener 130 presses the support member 123.

[0066] The fingerprint head 122 is a component for identifying fingerprints. After the fingerprint module 120 is installed in the mounting through hole 111, the front of the fingerprint head 122 is exposed from the mounting through hole 111, and the support member 123 is installed on the back of the fingerprint head 122. The fingerprint head 122 is installed on the support member 123 to support the fingerprint head 122. After the fingerprint module 120 is installed in the mounting through hole 111, the end of the fastener 130 contacts the surface of the support member 123 away from the fingerprint head 122 to press the fingerprint head 122, so as to ensure that the fingerprint head 122 is reliably installed in the predetermined position.

[0067] One end of the connecting wire 124 is electrically connected to the fingerprint head 122, and the other end of the connecting wire 124 extends from the mounting through hole 111 to the handle 110 and is electrically connected to the lock core. After the fingerprint head 122 recognizes the fingerprint, the unlocking signal is transmitted to the lock core through the connecting wire 124 to realize the unlocking control of the lock core. Optionally, the support member 123 has an opening 1231, one end of the connecting wire 124 passes through the fingerprint head 122 for connection, and the other end of the connecting wire 124 extends through the opening 1231.

[0068] Optionally, the support member 123 is a bracket, through which the fingerprint head 122 is supported. Of course, in other embodiments of the present application, the support member 123 can also be other components capable of supporting the fingerprint head 122, such as a support seat, etc. Optionally, the support member 123 and the fingerprint head 122 are fixed by gluing to ensure the reliability of the connection between the two.

[0069] Referring to Fig. 4, Fig. 11 and Fig. 12, in one embodiment, a protrusion 1232 is provided on the surface of the support member 123 away from the fingerprint head 122, and the protrusion 1232 abuts against the fastener 130. That is, one side surface of the support member 123 is protrudingly arranged, and after the fingerprint module 120 is installed in the installation through hole 111, the protrusion 1232 is located in the installation through hole 111, and the end of the fastener 130 can abut against the protrusion 1232, thereby realizing the pressing of the fingerprint module 120 to ensure the accurate installation position of the fingerprint module 120.

[0070] 4, 11 and 12, in one embodiment, the fingerprint module 120 further includes a gasket 125, which is disposed on the fingerprint head 122 and abuts against the support member 123. The gasket 125 is disposed between the fingerprint head 122 and the support member 123, and the gasket 125 bears the abutting force of the fastener 130 to ensure that the fingerprint module 120 is reliably pressed and fixed.

[0071] It can be understood that when the handle structure 100 is assembled, the end of the fastener 130 is pressed against the support member 123 of the fingerprint module 120, and the pressing force of the fastener 130 is transmitted to the gasket 125 through the support member 123. The gasket 125 can play a role of buffering compression to bear a certain pressing force, so that the fingerprint head 122 is better fixed in the mounting through hole 111.

[0072] Optionally, the gasket 125 is made of soft rubber material, and optionally, the gasket 125 is a compressible gasket 125. That is, the gasket 125 is a soft rubber gasket 125. A certain compression margin is reserved when the gasket 125 is designed, so as to eliminate the influence of the cumulative tolerance of the parts on the assembly of the handle structure 100, so that the fingerprint head 122 can be better fixed to the handle 110.

[0073] Optionally, the gasket 125 is connected to the fingerprint head 122 by gluing, and is also connected to the support member 123 by gluing. Optionally, the connecting wire 124 is fixed to the fingerprint head 122 by gluing to prevent the connecting wire 124 from being loosened.

[0074] Referring to FIG. 4 and FIG. 6 , in one embodiment, the end of the fastener 130 away from the fingerprint module 120 is further provided with a fixing hole 134, and the fixing hole 134 is used for the fixing member to pass through, so as to fix the handle 110 to the middle frame. The fastener 130 has a fixing hole 134, and the fixing hole 134 is located at the end of the fastener 130 away from the fingerprint module 120. The fixing member can pass through the limit cover of the middle frame and be installed in the fixing hole 134, so as to fix the handle 110 to the middle frame. Optionally, the fixing member is a screw.

[0075] When assembling the handle structure 100 of the present application, the gasket 125 is glued and fixed to the fingerprint head 122, and one end of the connecting wire 124 is glued and fixed to the fingerprint head 122, and the connecting wire 124 is electrically connected to the fingerprint head 122. The other end of the connecting wire 124 is extended through the opening 1231 of the support member 123, and then the support member 123 is glued and fixed to the gasket 125 to complete the assembly of the fingerprint module 120. The limiting protrusion of the fingerprint module 120 is matched with the positioning groove 118 on the inner wall of the installation through hole 111, and the fingerprint module 120 is guided and matched with the positioning protrusion 121 and the positioning groove 118, and then installed to the predetermined position in the installation through hole 111 through the installation channel 117. The fastener 130 is installed in the installation through hole 111 through the matching of the external thread and the internal thread, and the end of the fastener 130 presses against the protrusion of the support member 123 to press against the fingerprint module 120, and the assembly of the handle structure 100 is completed.

[0076] In the handle structure 100 of the present application, the fastener 130 is used to press and fix the fingerprint module 120 by matching the external thread with the internal thread, so that the fingerprint module 120 is reliably fixed in the handle 110. In this way, the fingerprint module 120 can be reliably fixed without using a complex structure, the number of parts is reduced, the assembly process is simplified, the assembly is convenient, and the production cost is effectively reduced. At the same time, the fastener 130 is fixed in the mounting through hole 111 of the handle 110 by using the external thread and the internal thread, and the structure is simple and reliable.

[0077] The present application also provides a door lock, comprising a middle frame, a fixing member, and a handle structure 100 as in any of the above embodiments, wherein the fixing member passes through the middle frame and is fixed to the handle 110 to connect the handle 110 to the middle frame. After the door lock of the present application adopts the handle structure 100 of the above embodiment, the lock cylinder in the door lock can be unlocked, and the production and assembly process of the door lock can be simplified.
