Description

Technical Field

[0001] This utility model relates to the field of door and window motor technology, specifically to a limiter and a roller shutter motor. Background Technology

[0002] The limit switch is used to adjust the positioning point for the up and down movement of curtains, and its performance directly affects the curtain adjustment accuracy. To meet torque requirements, current limit switch mounting bases are mostly made of one-piece molded metals such as aluminum alloy and zinc alloy. However, these metal mounting bases have significant drawbacks. In terms of accuracy, the mold opening accuracy of the zinc alloy mounting base determines the assembly and positioning accuracy of the limit switch; insufficient accuracy will directly reduce the curtain's limiting accuracy. Aluminum alloy molds, on the other hand, have lower precision than zinc alloy molds. In terms of cost, the high density of metals leads to higher manufacturing costs, and zinc alloy is more expensive than aluminum alloy. Therefore, it is clear that existing metal mounting bases cannot balance accuracy and cost, and cannot simultaneously meet the requirements of curtain adjustment accuracy and manufacturing cost.

The linkage component 200, limit component 300, adjustment component 400, and rotating component 500 are movably mounted on the support component 100. The linkage component 200 and the limit component 300 are connected by a transmission relationship, and the linkage component 200 is also connected by a transmission relationship with the rotating component 500. Simultaneously, the limit component 300 and the adjustment component 400 are also connected by a transmission relationship.

[0022] The load-bearing assembly 100 includes a transmission load-bearing member 110, a mounting load-bearing member 120, an adjusting mounting member 130, a wiring fixing member 140, and a load-bearing connector 150. The mounting load-bearing member 120 is located at one end of the transmission load-bearing member 110, while the adjusting mounting member 130 and the wiring fixing member 140 are respectively installed at the ends of the mounting load-bearing member 120 away from the transmission load-bearing member 110. The load-bearing connector 150 seals off the end of the mounting load-bearing member 120 away from the transmission load-bearing member 110, effectively preventing water from entering. The adjusting mounting member 130 is specifically used for installing the adjusting assembly 400, and the wiring fixing member 140 is responsible for fixing the power cord.

The adjustment mounting cavity 133 is composed of a first mounting groove 1331 and a second mounting groove 1332 that are interconnected. One end of the first mounting groove 1331 is connected to and corresponds to the end face of the adjustment mounting member 130 near the first adjustment connecting channel 122, and the other end is connected to one end of the second mounting groove 1332.

The transmission gear 220 is fixedly connected to the end of the linkage rod 210 near the mounting support 120, and the transmission gear 220 is exposed and meshes with the internal teeth of the rotating component 500. In this embodiment, the linkage rod 210 can be a rack.

[0026] The limiting assembly 300 includes a limiting transmission rod 310, a limiting moving gear 320, a washer 330, and a spring 340. One end of the limiting transmission rod 310 is rotatably mounted on the transmission support member 110, and the other end passes through the first adjusting connecting channel 122 and extends into the adjusting mounting member 130 to be connected to the adjusting assembly 400. The limiting moving gear 320 is rotatably sleeved on the limiting transmission rod 310 and meshes with the connecting rod 210. The washer 330 is sleeved on the end of the limiting transmission rod 310 near the mounting support member 120, and the spring 340 is sleeved on the limiting transmission rod 310 and located between the washer 330 and the mounting support member 120. With this fine-tuning structure, when the motor is powered off, when the adjusting component 400 drives the limiting transmission rod 310 to rotate, the limiting transmission rod 310 can drive the limiting moving gear 320 to move along the length direction of the linkage component 200, thereby adjusting the initial position of the limiting moving gear 320. In this embodiment, the limiting transmission rod 310 can be a screw.

One end of the adjustment transmission component 410 is fixedly connected to one end of the limiting transmission rod 310 that extends into the adjustment mounting component 130, and the other end is meshed with one end of the adjustment drive component 420. The other end of the adjustment drive component 420 is exposed through the second adjustment connecting channel 123. In this embodiment, the adjustment transmission component 410 and the adjustment drive component 420 are meshed together using a helical gear structure.

[0028] To improve the limiting accuracy, the limiting components 300 are configured in two sets and arranged symmetrically. Correspondingly, the first adjustment channel is configured as two lines, the adjustment mounting cavity 133 is configured as two lines, and the adjustment components 400 are also configured as two sets.

[0029] To improve waterproof performance, sealing rings are provided at the connections between the transmission support component 110 and the mounting support component 120, the connection between the connecting rod 210 and the mounting support component 120, the connection between the adjusting mounting component 130 and the adjusting mounting position 121, and the connection between the adjusting transmission component 410 and the second mounting groove 1332. This seals the connections between the components without affecting the assembly of the device. Through this structural design, the limiter achieves good limiting function and waterproof performance while improving assembly accuracy and reducing costs.

[0030] Example 2 This embodiment provides a roller blind motor. The roller blind motor includes a motor, a roller blind tube, and the limiter described in Embodiment 1. A roller blind is mounted on the outer wall of the roller blind tube. One end of the roller blind tube is connected to the motor output, and the other end is sleeved on the rotating part of the limiter. The motor drives the roller blind tube to rotate, thereby realizing the raising and lowering operation of the roller blind, and also driving the rotating part to rotate. By applying the limiter from Embodiment 1 to the roller blind motor, the raising and lowering position of the roller blind can be precisely controlled, improving the overall performance and safety of the roller blind motor. Through the coordinated work of the motor, roller blind tube, and limiter, efficient, stable, and precise raising and lowering functions of the roller blind are achieved.
