[0002] The laser beam beam consists of two parts: a transmitter and a receiver. The installation distance between them is 1-200 meters. The transmitter emits a beam of light, and the receiver receives the beam. After the laser beam beam is installed, it requires 3 or more professional technicians to adjust the beam. One person needs to adjust the pan-tilt unit of the transmitter to control the beam direction, one person needs to observe the changes in the beam position at the receiver to guide the adjustment personnel, and one person needs to use a laser beam finder to locate the direction of the light.
[0003] The beam adjustment is controlled by two screws on the XY axis of the gimbal. The common method is manual adjustment. The person at the transmitting end is responsible for manually adjusting the screws on the XY axis to adjust the beam. The person at the receiving end needs to observe the position of the beam and guide the person at the transmitting end on how to adjust the beam. In addition, a person needs to hold a light finder to find the trajectory of the beam movement. This method is time-consuming and laborious, and the adjustment accuracy cannot be guaranteed.

[0026] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] like Figure 1As shown, this utility model proposes a dimming device for adjusting the beam angle emitted by a laser beam intrusion detector. The laser beam intrusion detector is provided with a first adjustment position A and a second adjustment position B for adjusting the beam angle in the X-axis direction and the Y-axis direction, respectively. The dimming device includes a control module, a driving component 200, a switching mechanism 300, a first transmission mechanism 400, and a second transmission mechanism 500. The driving component 200 and the switching mechanism 300 are electrically connected to the control module. The first transmission mechanism 400 is connected to the first adjustment position A, the second transmission mechanism 500 is connected to the second adjustment position B, the driving component 200 is driven by the switching mechanism 300, and the switching mechanism 300 is driven by either the first transmission mechanism 400 or the second transmission mechanism 500. Under the control of the control module, the switching mechanism 300 switches between driving connections with either the first transmission mechanism 400 or the second transmission mechanism 500.
[0028] In this embodiment, the laser beam intrusion detector used in the dimming device employs a laser integrated module with application number 2025205113796. This module includes two fasteners for fine-tuning the emission angle of the light source emitter, referred to in this embodiment as the first adjustment position A and the second adjustment position B. The driving component 200 provides a power source, and the switching mechanism 300 guides the power source of the driving component 200 to the first transmission mechanism 400 or the second transmission mechanism 500. This allows for adjustment of the angle of the beam emitted by the laser beam intrusion detector, such as adjusting the angle of the beam in the X-axis direction. The switching mechanism 300 correspondingly switches its transmission connection with the first transmission mechanism 400, guiding the power source to the first transmission mechanism 400 and performing an adjustment operation on the first adjustment position A, thereby achieving the adjustment of the beam angle in the X-axis direction.
[0029] Furthermore, the dimming device also includes a remote control. The control module is equipped with a communication unit. The remote control communicates with the control module through the communication unit to control the drive unit 200 and the switching mechanism 300. The communication unit includes a 2.4G wireless module. Of course, the communication unit can also use Bluetooth, WIFI, wired communication and other communication methods.
[0030] Furthermore, the drive unit 200 includes a first drive motor 201 and a first gear 202 connected to the output end of the first drive motor 201. The first drive motor is used to drive the first gear 202 to rotate.
[0031] The switching mechanism 300 includes a second drive motor 301 and a second gear 302 connected to the output end of the second drive motor 301. The second gear 302 meshes with the first gear 202. The thickness of the first gear 202 is greater than the thickness of the second gear 302. The second drive motor 301 drives the second gear 302 to move along the thickness direction of the first gear 202.
[0032] The first transmission mechanism 400 includes a first transmission rod 401 and a first transmission gear 402 and a second transmission gear 403 meshing with each other. The first end of the first transmission rod 401 is connected to the axis of the second transmission gear 403, and the second end of the first transmission rod 401 is connected to the first adjustment position A. The second transmission mechanism 500 includes a second transmission rod 501 and a third transmission gear 502 and a fourth transmission gear 503 meshing with each other. The first end of the second transmission rod 501 is connected to the axis of the fourth transmission gear 503. The first transmission gear 402 and the third transmission gear 502 are independent of each other and coaxially arranged. Under the drive of the second drive motor 301, the second gear 302 moves along the thickness direction of the first gear 202 and meshes with the first transmission gear 402 or the third transmission gear 502.
[0033] Specifically, the thickness of the first gear 202 is greater than the total height of the first transmission gear 402 and the third transmission gear 502 when they are coaxially arranged, ensuring that the positions of the upper and lower ends of the first gear 202 correspond to the positions of the first transmission gear 402 and the third transmission gear 502, respectively. The second drive motor 301 drives the second gear 302 to move between the two ends of the first gear 202, so as to realize the meshing transmission of the second gear 302 with the first transmission gear 402 or with the second transmission gear 502, thereby guiding the power source of the first drive motor 201 to the first transmission gear 402 or the second transmission gear 502. The number of transmission gears in the first transmission mechanism 400 and the second transmission mechanism 500 can be selected according to the position of each adjustment position on the laser beam intrusion detector.
[0034] It should be noted that, since the second gear 302 may collide with the next transmission gear when switching to the corresponding transmission gear, the first drive motor 201 includes a geared motor with a rotation frequency of 8 revolutions per minute, which is a low-speed operating motor. The second drive motor 301 includes a self-holding electromagnetic push rod containing a strong magnet, so that when the first gear 302 switches to the next transmission gear, it automatically engages through low-speed rotation and the action of the strong magnet, thereby achieving normal and stable transmission switching function.
[0035] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
