[0039] Please refer to the attached document. Figures 1-5 This application provides a micro switch assembly 100, which is applied to a door lock device and is used by a user to lock the door.

[0040] Please refer to the attached document. Figures 1-5In this embodiment, the micro switch assembly 100 includes a door lock housing 10, a micro switch 20, a movable base 30, and a handle 40. The door lock housing 10 is installed on the door body and is located inside the door body. The micro switch 20 is built into the door lock housing 10 and has a switching part 21. The movable base 30 is built into the door lock housing 10 and moves relative to the door lock housing 10. The movable base 30 moves in the vertical direction. An operating rod 31 is connected to the movable base 30. The operating rod 31 passes through the door lock housing 10 and moves relative to the door lock housing 10 under the operation of the user. The handle 40 is rotatably connected to the door lock housing 10. The door lock housing 10 presses against the movable seat 30 when rotated, causing the movable seat 30 to move downward as the handle 40 rotates; when the movable seat 30 moves downward, it contacts the switch part 21, and the door lock device is in the unlocked state; when the movable seat 30 moves upward, it disengages from the switch part 21, and the door lock device is in the locked state, so that the handle 40 can drive the movable seat 30 to realize the state switching of the micro switch 20. This makes it easy for both the handle 40 and the operating lever 31 to control the state switching of the micro switch 20, avoiding the situation where only the operating lever 31 controls the micro switch 20, and improving the convenience of state switching of the micro switch assembly 100.

[0041] Please refer to the attached document. Figures 1-5 In this embodiment, the door lock housing 10 serves as a support component for the micro switch assembly 100, supporting the micro switch 20, the movable base 30, and the handle 40. The door lock housing 10 is installed on the door body and is located inside the door body, so that the micro switch assembly 100 can be fixed to the inside of the door body through the door lock housing 10.

[0042] The micro switch 20 is built into the door lock housing 10 so that the micro switch 20 can be fixed to the inside of the door lock housing 10; the micro switch 20 is provided with a switching part 21; the switching part 21 is located on the peripheral side wall of the micro switch 20.

[0043] The movable base 30 is built into the door lock housing 10 and moves relative to the door lock housing 10; the movable base 30 moves in the vertical direction to adjust its position relative to the door lock housing 10; the movable base 30 is connected to an operating lever 31, which passes through the door lock housing 10, with one end of the operating lever 31 exposed to the external environment, and moves relative to the door lock housing 10 under the operation of the user; so that the user can drive the movable base 30 to move in the vertical direction relative to the door lock housing 10 through the operating lever 31.

[0044] The handle 40 is rotatably connected to the door lock housing 10 to facilitate adjusting the position of the handle 40 relative to the door lock housing 10. When the handle 40 is rotated, it presses against the movable seat 30, causing the movable seat 30 to move downward as the handle 40 rotates. When the movable seat 30 moves downward, it contacts the switch part 21, and the door lock device is in the unlocked state. When the movable seat 30 moves upward, it disengages from the switch part 21, and the door lock device is in the locked state. This allows the handle 40 to drive the movable seat 30 to switch the state of the micro switch 20, thus enabling both the handle 40 and the operating lever 31 to control the state switching of the micro switch 20. This avoids the situation where only the operating lever 31 controls the micro switch 20, improving the convenience of state switching of the micro switch assembly 100.

[0045] Please refer to the attached document.

The moving seat 30 is movably connected to the inner shell 50 and moves up and down along the moving track 51 so that the moving seat 30 can move relative to the inner shell 50 through the moving track 51, thereby facilitating the adjustment of the vertical position of the moving seat 30 relative to the door lock housing 10. When the moving seat 30 moves downward, it contacts the switch part 21, and the door lock device is in the unlocked state. When the moving seat 30 moves upward, it disengages from the switch part 21, and the door lock device is in the locked state.

[0046] Please refer to the attached document. Figures 4-5 In this embodiment, the movable seat 30 includes a movable body 32 and a first protrusion 33. The movable body 32 is movably connected to the movable track 51 so that the movable seat 30 can move relative to the movable track 51 via the movable body 32. The first protrusion 33 is connected to the movable body 32 and is located on the peripheral sidewall of the movable body 32. The first protrusion 33 and the switch part 21 are on the same side. As the movable body 32 moves, the first protrusion 33 contacts the switch part 21 so that the movable seat 30 can control the switch part 21 to be in the open state via the first protrusion 33, thereby facilitating the door lock device to be in the unlocked state. As the movable body 32 moves, the first protrusion 33 disengages from the switch part 21 so that the switch part 21 is in the closed state, thereby facilitating the door lock device to be in the locked state.

[0047] Please refer to the attached document. Figures 4-5In this embodiment, the first protrusion 33 protrudes from the side wall of the moving body 32 toward the micro switch 20; one end of the first protrusion 33 is provided with an inclined portion 331, which is inclined in the vertical direction, and the end of the inclined portion 331 can contact the switching portion 21 of the micro switch 20; when the switching portion 21 of the micro switch 20 is contacted, the door lock device is in the unlocked state. When the moving body 32 moves toward the micro switch 20, the inclined portion 331 can first contact the switching portion 21 of the micro switch 20 and guide the switching portion 21 to slide along the inclined surface of the inclined portion 331, so that the switching portion 21 is gradually subjected to the pressure of the inclined portion 331 and triggers the switching portion 21 of the micro switch 20, thereby improving the triggering accuracy and reliability of the switching portion 21 of the micro switch 20.

[0048] Please refer to the attached document. Figures 4-5 In this embodiment, the moving body 32 is provided with a groove 32a. The inner contour of the groove 32a is fitted with the outer contour of the moving track 51 with a gap. The groove 32a is used for the moving track 51 to pass through, so that the moving body 32 can move relative to the inner shell 50 by cooperating with the moving track 51 through the groove 32a.

[0049] Please refer to the attached document. Figures 1-4 In this embodiment, the door lock housing 10 is provided with an elongated hole 10a, which is arranged along the vertical direction. The operating rod 31 is connected to the moving body 32 and passes through the door lock housing 10 along the front-back direction. The operating end of the operating rod 31 is located on the outside of the door lock housing 10. The operating rod 31 is movably passed through the elongated hole 10a to facilitate adjusting the position of the operating rod 31 relative to the elongated hole 10a. This allows the operating rod 31 to move vertically through the space of the elongated hole 10a, thereby facilitating the user to operate the operating rod 31 to drive the moving body 32 to move vertically.

[0050] Please refer to the attached document. Figures 1-2 In this embodiment, the inner shell 50 is provided with a transverse groove 50a; the micro switch assembly 100 also includes a spring 60 and a steel ball 70. The spring 60 is located within the transverse groove 50a and extends and retracts laterally along the transverse groove 50a to facilitate adjustment of the position of the spring 60 relative to the transverse groove 50a. The steel ball 70 contacts one end of the spring 60 and, under the elastic action of the spring 60, contacts the side wall of the moving body 32 facing away from the micro switch 20 to apply a damping force to the moving body 32. This allows the steel ball 70 to buffer the movement of the moving body 32 during movement, preventing the moving body 32 from moving too fast and affecting the performance of the switching part 21 of the micro switch 20. Optionally, the moving body 32 is arranged in a T-shape.

[0051] Please refer to the attached document. Figure 4In this embodiment, the micro switch assembly 100 further includes a lever 80, which is located inside the door lock housing 10 and connected to the handle 40. As the handle 40 rotates, the lever 80 contacts the moving body 32, causing the moving body 32 to move downwards. This allows the handle 40 to move the moving body 32 downwards via the lever 80, thus changing the door lock device from a locked state to an unlocked state. When the lever 80 disengages from the moving body 32, the moving body 32 moves upwards, changing the door lock device from an unlocked state to a locked state. This achieves state switching of the handle 40 controlling the micro switch 20, avoiding the need for only the operating lever 31 to control the micro switch 20, and improving the convenience of state switching of the micro switch assembly 100.

[0052] In a second embodiment, a door lock device includes a micro switch assembly 100, which is part of the door lock device. The main function of the door lock device is to prevent theft. When a door or window is locked, only the person with the correct key can open it, thereby effectively preventing intruders and loss of property.

[0053] At this time, the micro switch assembly 100 includes a door lock housing 10, a micro switch 20, a movable base 30, and a handle 40. The door lock housing 10 is installed on the door body and is located inside the door body. The micro switch 20 is built into the door lock housing 10 and has a switching part 21. The movable base 30 is built into the door lock housing 10 and moves relative to the door lock housing 10. The movable base 30 moves in the vertical direction. The movable base 30 is connected to an operating rod 31, which passes through the door lock housing 10 and moves relative to the door lock housing 10 under the operation of the user. The handle 40 is rotatably connected to the door lock housing. 10, and when rotating, it presses against the movable seat 30, so that the movable seat 30 moves downward as the handle 40 rotates; when the movable seat 30 moves downward, it contacts the switch part 21, and the door lock device is in the unlocked state; when the movable seat 30 moves upward, it disengages from the switch part 21, and the door lock device is in the locked state, so that the handle 40 can drive the movable seat 30 to realize the state switching of the micro switch 20, thereby making it easy for both the handle 40 and the operating lever 31 to control the state switching of the micro switch 20, avoiding the situation where only the operating lever 31 controls the micro switch 20, and improving the convenience of state switching of the micro switch assembly 100.
