[0053] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0054] Reference Figure 1 , Figure 2 and Figure 3 A novel side door self-resetting lock cylinder link mechanism includes a lock cylinder link 300, a housing 100, a reset spring 200 and a transmission component, wherein the housing 100 is a carrier for mounting the lock cylinder link 300, the reset spring 200 and the transmission component. The transmission component preferably includes a safety wheel 400, a transition rod 500 and a release rod 600, and the transmission component is used to transmit the transmission force of the lock cylinder link 300 after being actuated by any of the driving mechanism or the reset spring 200, thereby completing the unlocking function.

[0055] Reference Figure 4The lock core 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 space basis 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 through a pull rod or a pull wire, so that the user can actuate the key core mechanism through a key, and further actuate the rocker arm 3002 through a pull rod or a pull wire. The stop block 3006 is a raised edge structure arranged perpendicular to the surface of the lock core 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 close to the first mounting hole 3001 is mounted on the outer wall of the housing 100.

[0056] Reference Figure 4 The lock core connecting rod 300 further comprises a push rod 3003, a second limiting arm 3004 and a safety release position stop arm 3005. The push rod 3003 is preferably cylindrical, and its outer wall is a push rod cylindrical surface side wall 3003a, which protrudes and is perpendicular to the outer wall of the lock core 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 core connecting rod 300, and the second limiting arm 3004 is arranged at the misalignment of the first mounting hole 3001 and the rocker arm 3002, and the second limiting arm 3004 is preferably used to install one end of the reset spring 200. The safety release position stop arm 3005 is also perpendicular to the outer flange of the lock core connecting rod 300, and it is arranged at the side wall of the rocker arm 3002, and 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 limiting 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 under the unlocked state, the stop block 3006 is limited 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 lock body, thereby playing a role in waterproofing and drainage.

[0058] Reference Figure 5The housing 100 further includes a second connecting shaft 1002, a first limiting hole 1003 and a release limiting surface 1004. The second connecting shaft 1002 is used for the rotation of the safety wheel 400, so that the safety wheel 400 rotates with the second connecting shaft 1002 as the rotation center. The first limiting hole 1003 is used for installing the reset spring 200, which is a hole-shaped structure arranged on the surface of the housing 100. The release limiting 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 limiting surface 1004 and the neutral limiting surface 1005, the positions of the release position 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 reset spring 200 is connected between the lock core connecting rod 300 and the housing 100, and is used for resetting the lock core connecting rod 300 after being actuated by the driving mechanism. The reset spring 200 preferably includes a first spring leg 2001 and a second spring leg 2002. The first spring leg 2001 is arranged on the housing 100 through the first limiting hole 1003 and remains stationary; the second spring leg 2002 is arranged on the lock core connecting rod 300 through the second limiting arm 3004. The second limiting arm 3004 acts on the second spring leg 2002 to change the reset spring 200 between the pre-tightened state and the 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 reset spring 200, the first spring leg 2001 is also provided with a first spring leg first bend 2001a, the first spring leg first bend 2001a points in a direction 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, 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, and the second spring leg 2002 is folded as a whole and buckled at 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 arc-shaped protrusion protruding outward, and the flange 4001 is arranged below the side of the safety wheel 400 close to the lock cylinder connecting rod 300, and the state of the transition rod 500 is limited by the position change of the flange 4001. The second mounting hole 4002 cooperates with the second connecting shaft 1002 to actuate the safety wheel 400 to rotate around the second connecting shaft 1002, and the second mounting hole 4002 is sleeved on the outer wall of the second connecting shaft 1002. Among them, the trapezoidal through hole 4003 is used to cooperate with the push rod 3003 to actuate the trapezoidal hole structure of 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 unblocked position or the closed position, the push rod 3003 will not be actuated; when the push rod 3003 is in the unblocked position, the safety wheel 400 is also in the unblocked 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 shaft 1002 to the unblocked 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 driving force makes the retaining rib 5001 always contact with the flange 4001. When the safety wheel 400 rotates around the second connecting shaft 1002 to the release position, as the position of the flange 4001 changes, the retaining rib 5001 on the transition rod 500 drives the transition rod 500 to rotate under the driving force of the torsion spring. During this period, the retaining rib 5001 always contacts the outer wall of the flange 4001, so that the position of the transition rod 500 is stable. Among them, the hook 5002 is an outer protrusion extending outward, and a hook groove wall 50020 is formed between it and the transition rod 500. When the unlocking action is performed, the brake transition rod 500 slides downward, and the release rod 600 is rotated through the hook groove wall 50020 to complete the unlocking function.

[0063] Reference Fig. 9The 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 buckle 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, so that the hook groove wall 50020 is located above the anti-trip buckle 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 functional principle of the utility model can be explained through the following operation modes:

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

[0066] Reference Fig.12 When the driving mechanism actuates the rocker arm 3002 of the lock core connecting rod 300, the lock core connecting rod 300 rotates from the neutral position around the first connecting shaft 1001 to the released state, and the second spring leg 2002 is driven by the second limiting arm 3004 to drive the reset spring 200 to rotate from the pre-tightened state around the first connecting shaft 1001 to the output state. In 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 is made to rotate 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-disconnection 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-disconnection 6001 to cause the release rod 600 to rotate, thereby completing the unlocking function.

[0067] Reference Fig.13 and Fig.14 When the lock core connecting rod 300 is in the unlocked position, when the driving force of the driving mechanism disappears, the reset spring 200 rebounds from the output state first, and the second spring leg 2002 acts on the second limiting arm 3004, so that the reset 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 reset spring 200 stop moving. At this time, the reset 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 reset spring 200, stays in the neutral position. In this process, refer to Fig.15 and Fig.16 The push rod 3003 on the lock core connecting rod 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 connecting rod 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 Fig.17 , restricted by the stop block 3006 and the return spring 200, the lock core connecting rod 300 always remains in a 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 exposure. This structural design has no hidden dangers of water accumulation, and can divert water to the surface of the lock body at the first time to prevent water from flowing into the lock body, thereby playing a role in waterproofing and drainage.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
