[0002] Reflective laser sensors, with their advantages of non-contact detection, fast response speed, and high accuracy, are widely used in industrial automated production lines, object contour detection, distance measurement, and intelligent equipment control. Existing reflective laser sensors are mostly fixed using traditional structures such as bolt fastening, snap-fit, or adhesive bonding. Their core sensing components and mounting brackets are typically integrated or rigidly fixed using complex connectors.

[0003] However, traditional fixing methods have obvious limitations: on the one hand, the installation and disassembly process requires tools such as screwdrivers and wrenches, which is cumbersome and results in long hours and low efficiency when maintaining, replacing or adjusting the position of the sensor; on the other hand, some fixing structures may cause mechanical compression to the sensor housing or connecting wires, which can easily lead to tangling of connecting wires, excessive bending or deformation of the housing, affecting the stability of signal transmission and even shortening the service life of the equipment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a reflective laser sensor is provided.

[0025] like Figure 1-6 As shown, the reflective laser sensor according to an embodiment of the present invention includes a sensor structure 1, a docking structure 2 connected to the sensor structure 1, and a fixing structure 3 connected to the docking structure 2. The sensor structure 1 is fixedly docked with the fixing structure 3 through the docking structure 2, and the docking structure 2 and the fixing structure 3 realize the functions of convenient fixing and convenient disassembly of the sensor structure 1.

[0026] The sensor structure 1 includes a sensor housing 101, a filter 102, an indicator light 103, a connecting wire 104, a mating surface 105, and a magnetic block 106. The filter 102 and the indicator light 103 are installed on the outer surface of the sensor housing 101. A laser sensing integrated module is installed inside the sensor housing 101. The laser sensing integrated module is connected to the connecting wire 104. The mating surfaces 105 are provided on both sides of the outer housing of the sensor housing 101. A magnetic block 106 is fixedly installed on the mating surface 105.

[0027] Sensor structure 1 is the core functional carrier of the reflective laser sensor. Its components work together to realize the main function of laser sensing and the initial connection with docking structure 2. Sensor housing 101 serves as the overall frame, with the laser sensing integrated module installed inside and a filter 102, indicator light 103, and connecting cable 104 integrated externally. The filter 102 is used to filter ambient stray light to ensure accurate laser signal reception. The indicator light 103 provides real-time feedback on the sensor's working status through on / off or color changes. The connecting cable 104 connects to the laser sensing integrated module to realize signal transmission and power supply. The docking surfaces 105 on both sides of sensor housing 101 are symmetrical vertical surfaces. The magnetic blocks 106 fixed on them are the key interfaces for connecting with docking structure 2. Through magnetic attraction, sensor structure 1 and docking structure 2 are quickly pre-fixed, laying the foundation for a stable connection with the fixed structure 3 later. Overall, sensor structure 1 realizes the core detection function of reflective laser sensing through its internal modules, and at the same time, it forms a mechanical connection with docking structure 2 through docking surfaces 105 and magnetic blocks 106, ensuring the coordination of the main function and installation requirements.

[0028] The docking structure 2 includes a connecting plate 201, a magnetic groove 202, a fixing seat 203, a fixing rod 204, and a fixing knob 205. The magnetic groove 202 is provided on one side of the connecting plate 201, and the fixing seat 203 is fixedly connected to the other side of the connecting plate 201. The fixing rod 204 is fixedly connected to the fixing seat 203, and the fixing knob 205 is fixedly rotatably connected to the fixing rod 204. The connecting plate 201 is fixedly docked with the docking surface 105 of the sensor housing 101 by magnetic attraction of the magnetic block 106 through the magnetic groove 202.

[0029] The docking structure 2 serves as an intermediate bridge connecting the sensor structure 1 and the fixing structure 3. It achieves a stable connection and convenient disassembly through a combination of magnetic attraction and mechanical snap-fit. The connecting plate 201, as the core connector, has a magnetic groove 202 on one side that precisely engages with the magnetic block 106 on the docking surface 105 of the sensor structure 1. This magnetic attraction allows for quick docking of the connecting plate 201 and the sensor housing 101, enabling initial positioning without tools. The fixing seat 203 on the other side supports the fixing rod 204, which has an elliptical structure and can pass through the through hole 303 of the docking block 302 in the fixing structure 3. A fixing knob 2 is rotatably connected to the fixing rod 204. 05 is consistent with the contour of the fixing rod 204. After the fixing rod 204 is inserted into the through hole 303, the fixing knob 205 protrudes from the end face of the through hole 303. By rotating the fixing knob 205 so that its long axis is intersected with the short axis of the through hole 303, it can be snapped onto the docking block 302, realizing the relative fixation of the fixing rod 204 and the docking block 302. Through the magnetic pre-fixation of the magnetic groove 202 and the magnetic block 106, and the mechanical snapping of the fixing rod 204, the fixing knob 205 and the through hole 303, the docking structure 2 rigidly connects the sensor structure 1 and the fixing structure 3, while also taking into account the need for quick disassembly without tools, providing structural support for the convenient installation and maintenance of the overall sensor.

[0030] The fixing structure 3 includes a fixing frame 301, a docking block 302, a through hole 303, a magnetic base 304, and a fitting groove 305. The docking block 302 is fixedly connected to the inner side of the fixing frame 301. The through hole 303 is provided on the docking block 302 and fits with the fixing rod 204. The fixing rod 204 is elliptical. The top view of the fixing knob 205 is consistent with the fixing rod 204. The magnetic base 304 is fixedly connected to the outer surface of the fixing frame 301. The middle plate of the fixing frame 301 has a fitting groove 305 that fits with the connecting line 104.

[0031] The fixing structure 3 is the final carrier connecting the sensor to the mounting surface. It achieves convenient installation, disassembly, and stable fixation of the sensor through magnetic attraction and mechanical limiting. The fixing frame 301 serves as the main frame. The inner fixing block 302 has through holes 303 that precisely match the fixing rod 204 of the fixing structure 2, providing a through channel for the fixing rod 204. Combined with the snap-fit ​​action of the fixing knob 205, this achieves rigid fixation between the fixing structure 2 and the fixing frame 301. The magnetic base 304 on the outer surface is a switchable magnetic base. The magnetic strength can be controlled by a knob. When the knob is turned to the engaged state, the magnetic base 304 generates a strong magnetic force to attract the steel mounting surface. When turned to the released state, the magnetic force disappears, thus achieving fixation. The quick fixing and disassembly of the bracket 301 on the mounting surface gives the fixing structure 3 convenient operation characteristics. In addition, the fitting groove 305 opened in the middle plate of the fixing bracket 301 matches the contour of the connecting line 104 of the sensor structure 1, providing clearance for the connecting line 104 during sensor installation, avoiding the connecting line 104 from being squeezed, tangled or excessively bent, and ensuring the stability of signal transmission. Overall, the fixing structure 3 achieves convenient fixing to the mounting surface through the magnetic base 304, and supports the docking structure 2 through the docking block 302 and the through hole 303, finally fixing the sensor structure 1 stably in the target position. At the same time, the fitting groove 305 optimizes the layout of the connecting line, ensuring the structural stability and functional reliability of the sensor during operation.

[0032] In summary, with the aid of the above-mentioned technical solution of this utility model, the sensor housing 101, filter 102, indicator light 103, connecting wire 104, and laser sensing integrated module constitute the main body of the reflective laser sensor. The mating surface 105 and the magnetic block 106 are used to complete the fixed docking with the fixing structure 3 through the docking structure 2. The two mating surfaces 105 of the sensor housing 101 are symmetrical vertical planes. The connecting plate 201 is magnetically docked with the mating surface 105. The connecting plate 201 then passes through the fixing rod 204 on the fixing seat 203 and enters the through hole 303 of the mating block 302. The fixing rod 204 completes the through hole After the insertion of 303, the fixing knob 205 will protrude from the end face of the insertion hole 303. Since the outline of the fixing knob 205 is elliptical and the fixing rod 204 is the same, it will be locked onto the docking block 302 after rotation, so that the fixing rod 204 and the docking block 302 are relatively fixed. The magnetic base 304 is a switch-type magnetic base, and the magnetic effect can be controlled by the knob on it. In this way, the fixing bracket 301 can be magnetically attached to the steel of the mounting surface, thereby fixing the fixing bracket 301. The switch magnetic base has convenient fixing and convenient disassembly functions, so that the fixing structure 3 has convenient fixing and disassembly functions.
