[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] Reference Figure 1 、 Figure 2 and Figure 3 A novel self-resetting lock cylinder linkage mechanism for side doors includes a lock cylinder linkage 300, a housing 100, a return spring 200, and a transmission component. The housing 100 serves as a carrier for mounting the lock cylinder linkage 300, return spring 200, and transmission components. The transmission component preferably includes a safety wheel 400, a transition lever 500, and a release lever 600. The transmission component is used to transmit the transmission force of the lock cylinder linkage 300 after being activated by either the drive mechanism or the return spring 200, thereby completing the unlocking function.

[0055] Reference Figure 4The lock cylinder connecting rod 300 includes a first mounting hole 3001, a rocker arm 3002, and a stop block 3006. The first mounting hole 3001 and the rocker arm 3002 are arranged in a staggered plane to ensure a compact structure and provide a spatial foundation for the subsequent arrangement of the transmission structure. The rocker arm 3002 is actuated by a driving mechanism, which is a key core mechanism on a door handle in the prior art. The driving mechanism is connected to the hole on the rocker arm 3002 by a pull rod or a pull wire, so that the user can actuate the key core mechanism with a key and further actuate the rocker arm 3002 by the pull rod or the pull wire. The stop block 3006 is a raised edge structure arranged perpendicular to the surface of the lock cylinder connecting rod 300. The lower end of the raised edge structure is also provided with a bent and protruding water retaining edge 3007. The side of the stop block 3006 near the first mounting hole 3001 is mounted on the outer wall of the housing 100.

[0056] Reference Figure 4 The lock cylinder connecting rod 300 also includes a push rod 3003, a second limiting arm 3004, and an unlocking position stop arm 3005. The push rod 3003 is preferably cylindrical, and its outer wall is a push rod cylindrical side wall 3003a, which protrudes and is perpendicular to the outer wall of the lock cylinder connecting rod 300, and is used to further drive the safety wheel 400. The second limiting arm 3004 is perpendicular to the outer flange of the lock cylinder connecting rod 300 and is disposed at the offset between the first mounting hole 3001 and the rocker arm 3002. The second limiting arm 3004 is preferably used to mount one end of the return spring 200. The unlocking position stop arm 3005 is also perpendicular to the outer flange of the lock cylinder connecting rod 300 and is disposed on the side wall of the rocker arm 3002. It cooperates with the housing 100 to limit the maximum deflection angle of the rocker arm 3002.

[0057] Reference Figure 5 The structure of the housing 100 is as follows: the housing 100 is provided with a first connecting shaft 1001 and a neutral limit vertical surface 1005. The first mounting hole 3001 is sleeved on the outer wall of the first connecting shaft 1001, so that the lock core connecting rod 300 rotates with the first connecting shaft 1001 as the rotation center. The stop block 3006 is mounted on the outer wall of the neutral limit facade 1005. When the lock core connecting rod 300 is in the neutral position in the unlocked state, the stop block 3006 is restricted by the neutral limit facade 1005 of the shell 100. At this time, the stop block 3006 is overlapped on the neutral limit facade 1005 of the shell 100. The stop block 3006 covers the avoidance gap designed on the shell 100, effectively shielding the internal structure from being exposed, that is, the stop block 3006 and the water retaining edge 3007 below it have the effect of blocking and diverting water. Based on this structural design, there is no hidden danger of water accumulation, and water can be diverted to the surface of the lock body at the first time to prevent water from flowing into the inside of the lock body, thereby playing a role in waterproofing and drainage.

[0058] Reference Figure 5The housing 100 also includes a second connecting shaft 1002, a first limiting hole 1003 and a release safety limiting vertical surface 1004. The second connecting shaft 1002 is used for the rotation of the safety wheel 400, causing the safety wheel 400 to rotate with the second connecting shaft 1002 as the rotation center. The first limiting hole 1003 is used to install the reset spring 200, which is a hole-shaped structure arranged on the surface of the housing 100. The release safety limiting vertical surface 1004 is used to limit the deflection angle of the lock core connecting rod 300. When the rocker arm 3002 is actuated to rotate by the driving mechanism, based on the setting of the release safety limiting vertical surface 1004 and the neutral limiting vertical surface 1005, the positions of the release safety stop arm 3005 and the stop block 3006 are respectively limited, thereby controlling the deflection angle of the rocker arm 3002.

[0059] Reference Figure 6 The return spring 200 is connected between the lock cylinder connecting rod 300 and the housing 100 and is used to reset the lock cylinder connecting rod 300 after being actuated by the driving mechanism. The return spring 200 preferably includes a first spring leg 2001 and a second spring leg 2002. The first spring leg 2001 is mounted on the housing 100 through a first limiting hole 1003 and remains stationary. The second spring leg 2002 is mounted on the lock cylinder connecting rod 300 via a second limiting arm 3004. The second limiting arm 3004 acts on the second spring leg 2002 to change the return spring 200 between a preloaded state and an output state.

[0060] Reference Figure 6 Based on the setting of the first spring leg 2001 and the second spring leg 2002, further, in order to facilitate the installation of the return spring 200, the first spring leg 2001 is also provided with a first spring leg first bend 2001a, and the pointing direction of the first spring leg first bend 2001a is parallel to the axial direction of the first connecting shaft 1001 and is inserted into the first limiting hole 1003; the second spring leg 2002 is also provided with a second spring leg first bend 2002a and a second spring leg second bend 2002b, and the second spring leg first bend 2002a and the second spring leg second bend 2002b are in the same horizontal plane and perpendicular to the axial direction of the first connecting shaft 1001. The second spring leg 2002 is folded as a whole and is buckled against the outer wall of the second limiting arm 3004.

[0061] Reference Figure 7The safety wheel 400 includes a flange 4001, a second mounting hole 4002, and a trapezoidal through-hole 4003. The flange 4001 is an outwardly protruding arcuate protrusion located below the side of the safety wheel 400 near the lock cylinder connecting rod 300. The position of the flange 4001 controls the state of the transition rod 500. The second mounting hole 4002 engages with the second connecting shaft 1002, actuating the safety wheel 4000 to rotate about the second connecting shaft 1002. The second mounting hole 4002 is sleeved onto the outer wall of the second connecting shaft 1002. Among them, the trapezoidal through hole 4003 is a trapezoidal hole structure used to cooperate with the push rod 3003 to actuate the safety wheel 400, that is, the push rod 3003 moves in the trapezoidal through hole 4003, and the safety wheel 400 is actuated by the push rod 3003 against the inner wall of the trapezoidal through hole 4003. The inner wall of the trapezoidal through hole 4003 is the trapezoidal through hole side wall 4003a. The push rod 3003 is always matched in the trapezoidal through hole 4003 of the safety wheel 400. When the safety wheel 400 is in the unfastened position or the closed position, the push rod 3003 will not be actuated; when the push rod 3003 is in the unfastened position, the safety wheel 400 is also in the unfastened position. In this process, the push rod cylindrical side wall 3003a of the push rod 3003 actuates the trapezoidal through hole side wall 4003a of the safety wheel 400, so that the safety wheel 400 rotates around the second connecting axis 1002 to the unfastened position.

[0062] Reference Figure 8 The transition rod 500 includes a retaining rib 5001 and a hook 5002. The transition rod 500 is preferably supported by a torsion spring. Figure 1-Figure 3 The counterclockwise torsion spring force keeps the retaining rib 5001 in constant contact with the flange 4001. As the safety wheel 400 rotates about the second connecting shaft 1002 to the released position, the retaining rib 5001 on the transition lever 500, driven by the torsion spring force, rotates as the flange 4001 changes position. During this period, the retaining rib 5001 always contacts the outer wall of the flange 4001, maintaining a stable position for the transition lever 500. The hook 5002 is an outwardly extending protrusion, forming a hook groove wall 50020 between it and the transition lever 500. When unlocking, the brake transition lever 500 slides downward, causing the release lever 600 to rotate through the hook groove wall 50020, completing the unlocking function.

[0063] Reference Figure 9, the release rod 600 is provided with an anti-trip buckle 6001 that cooperates with the hook 5002, wherein the anti-trip buckle 6001 is a wave-shaped protrusion, and is provided with an anti-trip groove 60010 that cooperates with the hook 5002. When the push rod 3003 is in the unfastened position, the safety wheel 400 and the transition rod 500 are also in the unfastened position. During this process, the hook 5002 rotates toward the release rod 600 along with the transition rod 500, causing the hook groove wall 50020 to be located above the anti-trip groove 60010. Furthermore, when the unlocking action is performed, the brake transition rod 500 slides downward, and the hook groove wall 50020 cooperates with the anti-trip buckle 6001, causing the release rod 600 to rotate, thereby completing the unlocking function.

[0064] The present invention can be explained through the following operation mode:

[0065] The door lock is actuated from the closed safety state to the released safety state. Figure 10 and Figure 11 .

[0066] Reference Figure 12 When the driving mechanism actuates the rocker arm 3002 of the lock core connecting rod 300, causing the lock core connecting rod 300 to rotate from the neutral position around the first connecting shaft 1001 to the released state, the second spring leg 2002, under the action of the second limiting arm 3004, drives the return spring 200 to rotate from the pre-tightened state around the first connecting shaft 1001 to the output state. During this process, the cylindrical side wall 3003a on the push rod 3003 on the lock core connecting rod 300 actuates the trapezoidal through-hole side wall 4003a of the safety wheel 400. The safety wheel 400 rotates around the second connecting shaft 1002, and the flange 4001 of the safety wheel 400 limits the retaining rib 5001 of the transition rod 500. As the safety wheel 400 rotates, the transition rod 500 gradually causes the hook groove wall 50020 to turn to the top of the anti-trip groove 60010 under the action of the torsion spring. When the unlocking action is performed, the brake transition rod 500 slides downward, and the hook groove wall 50020 cooperates with the anti-trip 6001 to cause the release rod 600 to rotate, completing the unlocking function.

[0067] Reference Figure 13 and Figure 14 When the lock core connecting rod 300 is in the unlocked position, when the driving force of the driving mechanism disappears, the return spring 200 rebounds from the output state first, and the second spring leg 2002 acts on the second limiting arm 3004, so that the return spring 200 drives the lock core connecting rod 300 to rotate around the first connecting shaft 1001 at the same time. After the stop block 3006 contacts the neutral limiting vertical surface 1005 on the shell 100, the lock core connecting rod 300 and the return spring 200 stop moving. At this time, the return spring 200 is in a pre-tightened state, and the lock core connecting rod 300, which is restricted by the neutral limiting vertical surface 1005 of the shell 100 and the return spring 200, stays in the neutral position. In this process, refer to Figure 15 and Figure 16 The push rod 3003 on the lock core link 300 moves in the trapezoidal through hole 4003 of the safety wheel 400 without interference, and does not affect the safety wheel 400. Therefore, the process of the lock core link 300 moving from the unlocked position to the neutral position will not affect the unlocking action.

[0068] Since the lock core connecting rod 300 is restricted by the stop block 3006, the push rod 3003 cannot be used to actuate the trapezoidal through hole 4003 of the safety wheel 400 to move the safety wheel 400 to the closed safety state, that is, the lock core connecting rod 300 cannot realize the closed safety function.

[0069] Reference Figure 17 , restricted by the stop block 3006 and the return spring 200, the lock core connecting rod 300 always remains in the neutral position. At this time, the stop block 3006 is overlapped on the side of the shell 100, covering the avoidance gap designed on the shell 100, effectively shielding the internal structure from being exposed. This structural design has no hidden dangers of water accumulation, and can divert water to the surface of the lock body in the first time to prevent water from flowing into the interior of the lock body, thereby playing a role in waterproofing and drainage.

[0070] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
