AI Technical Summary
Existing electric suction door locks lack a power separation structure, which means that the door cannot be opened when the motor malfunctions. Furthermore, excessive stress on the pull rope affects its lifespan, and replacing the entire lock cylinder increases costs and is not environmentally friendly.
Design an electric suction door lock with a power separation mechanism, including a lock cylinder, a motor housing cable, a cable lever, a transmission rod, and a ratchet. Power separation is achieved through the unlocking lever and ratchet structure, ensuring that the door can be opened normally in the event of motor failure, and only the lock cylinder needs to be replaced to save costs and resources.
This allows the doors to open normally even in the event of a motor failure, reducing resource waste and costs, while maintaining the original vehicle signals and functions, ensuring safety and environmental friendliness.

[0002] Transmission electric suction door lock generally has no power separation structure, motor box with power separation structure, motor box pull rope is directly transmitted to electric suction door lock structure, usually it is to replace entire lock head, namely increase cost and cause waste product recycling, affect greening environmental protection.
[0003] The existing design has the following problems, which need to be improved:
[0004] 1. Electric suction door lock without power separation structure, when motor function is abnormal, leading to the door suction after opening the door.
[0005] 2. With motor box separation structure, due to structure and motor circuit and various reasons, leading to motor function abnormality, unable to open the door.
[0006] 3. Because motor box pull rope is directly transmitted to electric suction door lock structure, leading to pull rope stress too large, affect motor box pull rope strength and life.
[0007] 4. Only replace lock cylinder, without wasting car door lock control part, namely greening environmental protection, also has the resource saving and cost reduction. INVENTION CONTENTS
[0008] The utility model solves the technical problem: 1. power separation is carried out using original unlocking structure, reduces the risk of not opening the door, and ensures the smoothness of escape passage when vehicle is in danger;2. only replace lock cylinder on the basis of retaining original vehicle hub structure, namely save cost and ensure that original vehicle signal and function are intact.
[0009] To solve the above problems, the technical scheme adopted by the utility model is as follows: the utility model is an electric suction door lock with power separation mechanism, which comprises a central control system, a lock cylinder, a motor box pull rope, a pull rope lever, a transmission rod and a ratchet wheel, the lock cylinder is controlled by the central control system, the lock cylinder comprises a cover, the motor box pull rope is hinged to the cover, the motor box pull rope is controlled by the central control system, the pull rope lever is rotatably installed on the cover and is rotatably connected with the motor box pull rope output rod, the cover is provided with a sliding opening, the pull rope lever is hingedly arranged in the sliding opening, the transmission rod is rotatably arranged on the cover, and the ratchet wheel is rotatably installed on the cover and is in contact with the transmission rod.
[0010] Further, the face cover is provided with a failure pushing structure, the failure pushing structure comprises an unlocking lever, a pawl and a clutch lever, the unlocking lever is rotationally installed on the face cover, the pawl is rotationally installed on the face cover and is in contact connection with the unlocking lever, the pawl is in contact connection with the ratchet wheel, and the clutch lever is rotationally installed on the face cover and is in contact connection with the unlocking lever, and the clutch lever is in contact connection with the transmission rod.
[0011] The beneficial effects achieved by the utility model are as follows: the risk that the door lock is pulled by the motor box and cannot be unlocked to affect the opening of the automobile door and the escape in an emergency situation is avoided; only the lock core is replaced, the signals and functions of the original automobile central control are reserved, the safety and perfection of the original automobile are ensured, the cost is reduced, resource waste is reduced, and the effect of greening, environmental protection and energy saving is achieved. BRIEF DESCRIPTION OF DRAWINGS
[0012] Fig. 1 A schematic diagram of the overall structure of the electric suction door lock with the power separation mechanism is provided for the utility model;
[0013] Fig. 2 A schematic diagram of the structure of the electric suction door lock with the power separation mechanism from another angle is provided for the utility model;
[0014] Fig. 3 A schematic diagram of the structure of the electric suction door lock with the power separation mechanism to which a torsion spring is added is provided for the utility model.
[0015] Among them, (1), lock core, (2), face cover, (3), motor box cable, (4), cable lever, (5), transmission rod, (6), ratchet wheel, (7), failure pushing structure, (8), unlocking lever, (9), pawl, (10), clutch lever. DETAILED DESCRIPTION
[0016] As shown in the description accompanying drawings Figs. 1-3 The utility model discloses a kind of electric suction door locks with power separation mechanism, including central control system, further including lock core (1), lock core (1) is controlled by central control system, lock core (1) includes face cover (2), motor box cable (3), cable lever (4), transmission rod (5) and ratchet wheel (6), motor box cable (3) is installed on face cover (2) with snap, motor box cable (3) is controlled by central control system, cable lever (4) is rotationally installed on face cover (2) and is rotationally connected with the output rod of motor box cable (3), face cover (2) is provided with sliding port, cable lever (4) is snap slidably arranged in sliding port, sliding port provides track for the sliding of cable lever (4), transmission rod (5) is rotationally arranged on face cover (2), by torsion spring limit initial position, ratchet wheel (6) is rotationally installed on face cover (2) and is in contact connection with transmission rod (5).
[0017] As shown in the accompanying drawings Figs. 1-3 The face cover (2) is provided with a failure pushing structure (7), which includes an unlocking lever (8), a pawl (9) and a clutch lever (10). The unlocking lever (8) is rotatably installed on the face cover (2). The pawl (9) is rotatably installed on the face cover (2) and in contact with the unlocking lever (8). The pawl (9) is in contact with the ratchet wheel (6). The clutch lever (10) is rotatably installed on the face cover (2) and in contact with the unlocking lever (8). The clutch lever (10) is in contact with the transmission rod (5). The clutch lever (10) is defined by a torsion spring to have an initial position.
[0018] In specific use: when the ratchet wheel (6) reaches the half-lock state in the door closing state, a signal is received. The motor box pulls the cable lever (4) under the action of the motor box. The cable lever (4) changes the transmission ratio by changing the center of the rotating shaft and drives the transmission rod (5). The transmission rod (5) drives the ratchet wheel (6) to rotate, thereby achieving the door closing state.
[0019] When the motor box fails, the cable lever (4) will be pulled by the motor box cable (3), causing the transmission rod (5) to fail to reset. The transmission rod (5) is in contact with the ratchet wheel (6) and cannot be unlocked. At this time, when the central control unlocking mechanism triggers the unlocking lever (8), the unlocking lever (8) pushes the pawl (9) to move while pushing the clutch lever (10). The clutch lever (10) pushes the transmission rod (5) away from the ratchet wheel (6). At this time, the ratchet wheel (6) can be unlocked to open the door.
[0020] It should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
