[0040] Please refer to the attached document. Figures 1-3 The present invention provides a door lock ring assembly 100, which is applied to a car door device to lock or unlock the door.

[0041] Please refer to the attached document. Figures 1-3 In this embodiment, the door lock ring assembly 100 includes a housing 10, a door bracket 20, and a lock ring module 30. The door bracket 20 is disposed on the outer side of the housing 10, and the lock ring module 30 is disposed on the inner side of the housing 10. The lock ring module 30 is connected to the housing 10. The lock ring 33 of the lock ring module 30 is locked to or disengaged from the door bracket 20 under the drive of the motor 31 of the lock ring module 30, so that the housing 10 and the door bracket 20 are in a locked state or a non-locked state. This allows the motor 31 of the lock ring module 30 to drive the lock ring 33 of the lock ring module 30 to achieve an automatic locking state between the housing 10 and the door bracket 20, avoiding the use of self-closing locking and improving the opening and closing convenience of the door lock ring assembly 100.

[0042] Please refer to the attached document. Figures 1-3 In this embodiment, the outer shell 10 serves as a supporting component of the door lock ring assembly 100. The outer shell 10 is used to support the lock ring module 30. The door bracket 20 is disposed on the outside of the outer shell 10 and is used to fix the vehicle body.

[0043] Please refer to the attached document. Figures 1-4In this embodiment, the locking ring module 30 is disposed inside the housing 10. The locking ring module 30 is mounted on the housing 10 and includes a motor 31, a first transmission module 32, and a locking ring 33. The first transmission module 32 is located between the motor 31 and the locking ring 33. One end of the first transmission module 32 is connected to the output end of the motor 31, so that the motor 31 drives the first transmission module 32 to rotate, thereby facilitating the adjustment of the position of the first transmission module 32. The other end of the first transmission module 32 is connected to the locking ring 33, so that the locking ring 33 moves with the first transmission module 31. The first transmission module 32 rotates and swings, causing the locking ring 33 to swing relative to the outer shell 10. Under the drive of the motor 31 and the first transmission module 32, the locking ring 33 locks onto or disengages from the door bracket 20, so that the outer shell 10 and the door bracket 20 are in a locked or unlocked state. This allows the motor 31 to drive the locking ring 33 to achieve an automatic locking state between the outer shell 10 and the door bracket 20, avoiding the use of self-closing locking and improving the opening and closing convenience of the door locking ring assembly 100.

[0044] Please refer to the attached document. Figures 1-3 At this time, the fixed end of the motor 31 is installed on the housing 10 to fix the motor 31 to the housing 10. The first transmission module 32 is a worm gear transmission module. The worm end of the worm gear transmission module is connected to the output end of the motor 31 so that the motor 31 drives the worm end of the worm gear transmission module to rotate. The worm end of the worm gear transmission module is rotatably connected to the housing 10 to adjust the position of the worm end of the worm gear transmission module relative to the housing 10. The worm end of the worm gear transmission module meshes with the worm end of the worm gear transmission module so that the worm end of the worm gear transmission module moves with the worm of the worm gear transmission module. The locking ring 33 rotates with the rotation of the rod end, and is connected to the worm wheel end of the worm gear transmission module. It swings relative to the outer shell 10 as the worm wheel end of the worm gear transmission module rotates. The locking ring 33 is locked to or disengaged from the door bracket 20 under the drive of the worm wheel end of the worm gear transmission module, so that the outer shell 10 and the door bracket 20 are in a locked or unlocked state. This allows the motor 31 to drive the locking ring 33 through the worm gear transmission module to achieve an automatic locking state for the outer shell 10 and the door bracket 20, avoiding the use of self-priming locking and improving the opening and closing convenience of the door locking ring assembly 100.

[0045] Please refer to the attached document. Figure 1 and 6The locking ring 33 includes a locking ring body 331 and a locking ring part 332. The locking ring body 331 is connected to the worm wheel end of the worm gear transmission module so that the locking ring body 331 is fixed to the worm wheel end of the worm gear transmission module. The locking ring body 331 rotates with the rotation of the worm wheel end of the worm gear transmission module so as to adjust the position of the locking ring body 331. The locking ring part 332 is disposed on one side of the locking ring body 331. The locking ring part 332 is connected to the locking ring body 331 and locks onto or disengages from the door bracket 20 with the rotation of the locking ring body 331, so that the locking ring part 332 and the door bracket 20 are in a locked state or a non-locked state.

[0046] Please refer to the attached document. Figures 1-2 The door bracket 20 is provided with a locking hole 20a. The locking ring part 332 is inserted into the locking hole 20a and locked to the door bracket 20, so that the locking ring part 332 can lock or disengage from the door bracket 20 through the locking hole 20a, so that the outer shell 10 and the door bracket 20 are in a locked state, thereby achieving automatic locking and avoiding the use of self-closing locking, thus improving the opening and closing convenience of the door locking ring assembly 100.

[0047] Optionally, the locking hole 20a is arranged in a U-shape and extends horizontally. The diameter of the locking hole 20a is larger than that of the locking ring 332, so that the locking ring 332 can be inserted into or disengaged from the locking hole 20a during rotation.

[0048] Please refer to the attached document. Figures 1-2 The locking ring body 331 is connected to the worm wheel end of the worm gear transmission module via a rotating shaft and is located on the upper side of the worm wheel end of the worm gear transmission module, so that the locking ring body 331 can rotate along the axis of the rotating shaft. This facilitates the locking ring body 331 to drive the locking ring part 332 to rotate along the axis of the rotating shaft, thereby facilitating the locking ring part 332 to lock onto or disengage from the door bracket 20 as the locking ring body 331 rotates. This allows the locking ring part 332 and the door bracket 20 to be in a locked or unlocked state. The locking ring 33 is driven by the motor 31 to achieve the locking or unlocked state of the outer shell 10 and the door bracket 20, thereby realizing automatic locking and avoiding the use of self-closing locking, thus improving the opening and closing convenience of the door locking ring assembly 100.

[0049] Please refer to the attached document. Figure 1 and 5 The door lock ring assembly 100 also includes a micro switch 40, which is located on the outside of the motor 31 and mounted on the housing 10. The micro switch 40 has a switch end 41, and the worm wheel end of the worm gear transmission module has a protruding extension 321. The protruding extension 321 contacts or disengages from the switch end 41 as the worm wheel end of the worm gear transmission module rotates, so that the protruding extension 321 can trigger the opening or closing of the switch end 41 during rotation.

[0050] Please refer to the attached document. Figure 1 and 5 The protrusion 321 is provided on the upper surface of the worm wheel end of the worm gear transmission module. The protrusion 321 extends along the arc direction so that the protrusion 321 and the switch end 41 are on the same horizontal plane.

[0051] Please refer to the attached document. Figure 1 and 5 The protrusion 321 includes a first protrusion body 3211 and a second protrusion body 3212. The first protrusion body 3211 extends along an arc direction, and the second protrusion body 3212 is connected to the first protrusion body 3211 and extends along an inclined direction. The second protrusion body 3212 is used to contact the switch end 41 of the micro switch 40, so that the protrusion 321 can contact or detach from the switch end 41 through the second protrusion body 3212, so that the protrusion 321 can trigger the opening or closing of the switch end 41 during rotation.

[0052] Working process: Under the driving action of motor 31, the worm end of the worm gear transmission module rotates. The worm wheel end of the worm gear transmission module rotates along with the worm end of the worm gear transmission module, so that the worm wheel of the worm gear transmission module drives the locking ring 33 to rotate through the rotating shaft. This facilitates the locking ring 33 to lock onto or disengage from the door bracket 20, so that the outer shell 10 and the door bracket 20 are in a locked or unlocked state. When motor 31 is in the forward rotation state, the worm gear transmission module moves in the unlocking direction, and the locking ring 33 disengages from the door bracket. When the frame 20 moves in the direction of rotation, the protrusion 321 of the worm gear transmission module contacts the switch end 41, so that the micro switch 40 is turned on and an unlocking signal is activated, so that the housing 10 and the door bracket 20 are in a non-locked state. When the motor 31 is in the reverse state, the worm gear transmission module moves in the locking direction, the locking ring 33 moves in the direction of insertion into the door bracket 20, and the protrusion 321 of the worm gear transmission module disengages from the switch end 41, so that the micro switch 40 is closed and a locking signal is activated, so that the housing 10 and the door bracket 20 are in a locked state.
