Description

Technical Field

[0001] This disclosure relates to the field of motor vehicle lock technology, and more particularly to a lock device with central locking function for an electric door cover system of an automobile. Background Technology

[0002] With the development of automotive technology, the requirements for the safety and convenience of automotive electric door and hatch systems (including automotive electric side door systems and automotive electric tailgate systems) are becoming increasingly higher. It is necessary to continuously improve and optimize the electromechanical structure of the locking device of automotive electric door and hatch systems to improve the operation and safety performance of the locking device.

[0003] For example, Chinese patent CN202222661624.0 describes a central locking device that can be used on car covers (tailgates or trunks) and side doors. It includes an inward-opening emergency unlocking device, a child safety device, and an outward-opening emergency unlocking device (outer operating lever). When the car's electric door cover system is electrically locked, or when the electric unlocking device malfunctions (e.g., in the event of a power outage), occupants can use the inward-opening emergency unlocking device to perform an emergency unlocking operation. The child safety device allows the inward-opening emergency unlocking device to switch between states where emergency unlocking is possible and incapable, preventing accidental operation by children inside the vehicle. However, the mechanical unlocking device described in this patent uses an outer operating lever driven by a transition operating lever to push a first pawl, thus unlocking the device from the outside. The outer operating lever and the first pawl are always connected by a transmission mechanism, meaning the first pawl can always be pushed by the outer operating lever to forcibly unlock the device, posing a certain safety hazard.

[0004] The functions of the internal and external emergency unlocking devices in Chinese patent CN202222661624.0 can be further improved and optimized. Summary of the Invention

The inner opening connecting rod 5010 is connected to the central control gear 5001 through the central control gear second feature 50012. The central control gear 5001 transmits the motion of the central control gear 5001 to the inner opening drive rod 5011 through the central control gear second feature 50012.

[0078] refer to Figure 11 In a preferred embodiment of this disclosure, the emergency lever 5013 is designed with a first emergency lever feature 50131 and a second emergency lever feature 50132. The inward-opening connecting rod 5010 is designed with the first inward-opening connecting rod feature 50101. The emergency lever 5013 can be used to operate tools ( Figure 11Under the action of (not shown, such as various mechanical tools), the emergency lever first feature 50131 rotates, at which time, the emergency lever first feature 50131 pushes the inner opening connecting rod first feature 50101 to move, and through the inner opening connecting rod first feature 50101, it drives the inner opening connecting rod 5010 to move (…). Figure 11 (From left to right), thus driving the central control gear 5001 to move to Figure 12 The above-mentioned safety position means that the central clutch lever 5002 is disengaged from the first feature 40041 of the central device, that is, the central control gear 5001 pushes the central clutch lever 5002 to disconnect the transmission chain of the external mechanical unlocking device 7001 based on the third feature 50013 of the central control gear, thereby realizing the vehicle safety locking in an emergency.

[0079] Continue to refer to Figure 11 The second feature 50132 of the emergency lever provides an elastic force to the emergency lever 5013. It is preferably an elastic arm, whose elastic force causes the emergency lever 5013 to tend to move towards its initial position. Preferably, the second feature 50132 of the emergency lever is a curved elastic arm, which generates the elastic force through contact between its outer arm surface and the inner connecting rod 5010. Those skilled in the art, guided by the technical solutions of this disclosure, can make appropriate adjustments to the structure and type of the emergency lever 5013 and the second feature 50132 of the emergency lever, all of which fall within the protection scope of this disclosure.

[0080] Figure 13 The structure of a child safety device 600 with a central locking function of a locking device 1000 according to one embodiment of the present disclosure is shown.

[0081] refer to Figure 13 The child safety device 600 includes a child safety motor 6001, a child safety worm gear 6002, a child safety gear 6003, a child safety linkage 6004, a child safety switch 6005, a child safety linkage spring 6006, and a child safety gear spring 6007. Detailed structure and working principle of the child safety device 600 can be found in the applicant's prior Chinese patent CN202222661624.0. Further details are omitted here.

[0082] Figures 14 to 16 The structure of the mechanical unlocking device 700 of a lock device 1000 with central control function according to one embodiment of the present disclosure is shown.

[0083] refer to Figure 14Preferably, the mechanical unlocking device 700 of this disclosure includes an externally opening mechanical unlocking device 7001. The externally opening mechanical unlocking device 7001 is designed with an externally opening mechanical unlocking device first hole 70011. The externally opening mechanical unlocking device 7001 is connected to an external operating mechanism (e.g., external handle, lock cylinder mechanism, etc.) through the externally opening mechanical unlocking device first hole 70011, transmitting the movement and power of the external operating mechanism to the externally opening mechanical unlocking device 7001. This causes the externally opening mechanical unlocking device 7001 to drive the central control drive rod 5003 of the central control device 500 to move (rotate around the rotation axis), the central control drive rod 5003 drives the central control clutch rod 5002 to move, and the central control clutch rod 5002 pushes the central control device 4004 to move. Figure 14 (When rotated counterclockwise), the central device 4004 pushes the pawl component 102 of the locking device 100 to move, thereby realizing the external mechanical unlocking of the locking device 100.

[0084] refer to Figure 15 The mechanical unlocking device 700 disclosed herein also includes an inward-opening mechanical unlocking device 7002. The inward-opening mechanical unlocking device 7002 is designed with an inward-opening mechanical unlocking device first hole 70021, which connects to an in-vehicle operating mechanism (e.g., an interior handle) to transmit the movement and power of the in-vehicle operating mechanism. The inward-opening mechanical unlocking device 7002 is designed with an inward-opening mechanical unlocking device second feature 70022 (a protruding feature), and the inward-opening drive rod 5011 is designed with an inward-opening drive rod fourth feature 50114. When the inward-opening mechanical unlocking device 7002 moves upward under the actuation of the in-vehicle operating mechanism, the inward-opening mechanical unlocking device second feature 70022 actuates the inward-opening drive rod fourth feature 50114 (causing the inward-opening drive rod 5011 to rotate clockwise, such as...). Figure 15 The inner opening drive rod 5011 will push the central control gear 5001 back to the initial position, thereby enabling the transmission chain of the outer opening mechanical unlocking device 7001 to be reconnected.

[0085] Continue to refer to Figure 15 In a preferred embodiment of this disclosure, the internally opening mechanical unlocking device 7002 is designed with a third feature 70023 for attaching the other end of the mechanical unlocking device return spring 5005. Through this structural design, the mechanical unlocking device return spring 5005 of this disclosure can apply an elastic force to the internally opening mechanical unlocking device 7002, causing the internally opening mechanical unlocking device 7002 to tend to move towards its initial position.

[0086] Figure 15The installation method of the reset spring 5005 of the mechanical unlocking device is illustrated by way of example. Under the guidance of the technical solution of this disclosure, those skilled in the art can make adjustments to the installation method, specific type, etc. of the reset spring 5005 of the mechanical unlocking device, all of which fall within the protection scope of this disclosure.

[0087] refer to Figure 16 The child safety device 600 features a child safety gear 6003 with a child safety gear groove 60031. The child safety linkage 6004 has a first child safety linkage feature 60041 and a second child safety linkage feature 60042. The internally opening mechanical unlocking device 7002 has an internally opening mechanical unlocking device groove 70024. The first child safety linkage feature 60041 can move within the child safety gear groove 60031. The second child safety linkage feature 60042 can move within the internally opening mechanical unlocking device groove 70024.

[0088] When the central control gear 5001 from Figure 6 The safety release position shown moves to Figure 8 When the safety lock is engaged, the central control gear 5001 drives the inner opening drive rod 5011 via the inner opening connecting rod 5010. The inner opening drive rod 5011 then pushes the first feature 60041 of the child safety linkage via the second feature 50112, causing the second feature 60042 of the child safety linkage to slide in the inner opening mechanical unlocking device groove 70024. This disengages the second feature 60042 of the child safety linkage from the third feature 40043 of the central device, preventing the inner opening mechanical unlocking device 7002 from driving the central device 4004. This disconnects the transmission chain of the inner opening mechanical unlocking device 7002, thus engaging the safety lock of the inner opening mechanical unlocking device 7002.

[0089] Figure 17 and Figure 18 The external overall structure of a locking device 1000 with central control function according to one embodiment of the present disclosure is shown from different angles. Figure 18 The diagram also shows the base plate 103 of the locking device 1000, on which the bolt member 101 and the pawl member 102 described above are rotatably mounted. Those skilled in the art, inspired by the technical solutions of this disclosure, have made modifications for space allocation and protection purposes.
