Embodiment 1

[0038] figure 1 It is a schematic structural diagram of the unlocking mechanism 100 provided in this embodiment, figure 2 For an exploded schematic diagram of the unlocking mechanism 100, please refer to figure 1 and figure 2 shown.

[0039] The unlocking mechanism 100 includes a gear screw 13 and a claw 16 that mesh with each other. The gear screw 13 includes a rotating shaft 132 provided with a helical protrusion 134. The claw 16 includes an engaging portion 162 and a first limiting portion for limiting the rotation of the gear screw 13. 18.

[0040] The unlocking mechanism 100 has a first state in which the meshing portion 162 meshes with the spiral protrusion 134, and the gear screw 13 drives the claw 16 to rotate toward the first direction 11, and the first position limiting portion 18 cooperates with the spiral protrusion 134 to limit the position. Under the action of an external force, the claw 16 rotates toward the second direction 12 opposite to the first direct...

Embodiment 2

[0070] Embodiment 2 of the present invention provides an automobile door lock, including the unlocking mechanism 100 provided in Embodiment 1.

[0071] Figure 8 It is a schematic diagram of the car door lock in the locked position, Figure 9 For a schematic diagram of the car door lock in the unlocked position, please refer to Figure 8 and Figure 9 shown, the specific instructions are as follows:

[0072] The car door lock also includes a lock catch 20 and a card plate 21. The lock catch 20 is rotatably arranged on the housing 10 of the unlocking mechanism 100 through a riveting shaft, and the lock catch 20 is fixed on the vehicle body. The car door lock includes a motor device part and a The mechanical lock machine part, in which the motor device part integrates the motor and the optimized gear screw 13, the motor is used as the power source, and the gear screw 13 is used as the transmission medium; the mechanical lock machine part mainly maintains the mechanical reliab...

Abstract

The invention discloses an unlocking mechanism and an automobile door lock and relates to the technical field of automobiles. The unlocking mechanism comprises a gear screw rod and a jack catch whichare engaged mutually. The gear screw rod comprises a rotary shaft provided with a spiral protrusion. The jack catch comprises an engagement part and a first limiting part used for limiting rotation ofthe gear screw rod. The unlocking mechanism is provided with the engagement part and the spiral protrusion which are engaged. Moreover, the gear screw rod drives the jack catch to rotate towards thefirst direction in the first state to be matched with the limiting part and the spiral protrusion to conduct limiting. Under the action of external force, the jack catch rotates to the second direction opposite to the first direction to restore in the second state. The unlocking mechanism is ingenious and reasonable in design. Through the spiral boss and an involute rotary boss designed on the gear screw rod, the number of the parts of the whole mechanism is greatly reduced, the unlocking mechanism is convenient to assemble, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an unlocking mechanism and an automobile door lock. Background technique [0002] At present, most of the door locks on automobiles at home and abroad use electric door locks, which use the high-speed motor in the lock body to transmit the power output through the transmission mechanism. The reciprocating small-angle swing of the swing arm on the lock body requires multi-stage parts to achieve deceleration. [0003] Often in the process of manufacturing and processing these parts, the assembly process and control process are more complicated, resulting in higher production costs. Contents of the invention [0004] The purpose of the present invention is to provide an unlocking mechanism, which reduces the number of parts of the mechanism, facilitates assembly, and reduces production costs. [0005] Embodiments of the present invention are achieved like this: [0006] Bas...
