Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser line projectors, in particular to a novel window cover for laser line projectors. Background Art
[0002] A laser line projector is a measuring tool used in the fields of construction and decoration. It uses lasers to project horizontal and vertical lines, helping users to perform precise alignment and positioning work. Traditional laser levels use buttons to control the turning on and off of the laser transmitter. Frequent use of physical buttons will cause them to wear, affecting the sensitivity and service life of the buttons. Long-term use may cause the buttons to fail, thus affecting the normal function of the laser level. The user needs to be familiar with the correspondence between the different buttons of the laser level and the laser in order to turn the laser on and off, which is relatively cumbersome to use. In addition, the traditional button design requires the user to press hard to switch the laser transmitter on and off. The process of pressing the button will cause the machine to move. When the machine is placed on the ground, the buttons of the level are generally on the side of the machine body, which is not convenient and intuitive for the user to operate.
[0003] The intelligent laser line level recorded in the patent document with announcement number CN214666828U can be turned on and off, the laser line module can be controlled to project a reference line, and the screen display information can be set by pressing buttons. By projecting a reference line through the laser line module, the angle sensor can accurately detect the current angle of the intelligent laser line level and display the detected angle on the screen to detect the horizontality of the surface of the object being measured. This intelligent laser line level is started or turned off by a traditional button, which requires the user to press hard. In the process of pressing the button, the machine will be displaced, resulting in poor accuracy of the detection result, affecting construction efficiency.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0027] In one embodiment, Figure 1-Figure 5As shown, a new type of laser line projector window cover includes a shell 101, and the shell 101 is provided with a mounting groove 102 for facilitating the installation of the laser line projector. A mainboard 104 for driving the laser line projector is installed inside the shell 101, and a sensing chip is welded on the surface of the mainboard 104. The output end of the sensing chip is connected to the main control IO port of the line projector. A mechanical button 103 is provided on the mainboard 104 for transmitting instructions to the sensing chip to start or shut down the laser line projector in different directions. The mainboard 104 is electrically connected to the touch structure for turning on or off the laser line projector. A protective mechanism is provided at the upper end of the shell 101 to provide protection for the laser line projector window cover. The shell 101 provides installation conditions for the mainboard 104. By pressing the mechanical button 103, the mechanical button 103 transmits instructions to the sensing chip on the mainboard 104, and the signal is transmitted to the main control of the line projector through the sensing chip. The line projector laser starts to emit laser, and a corresponding transportation device is installed through the mounting groove 102 to facilitate the installation and movement of the laser line projector.
[0028] In one embodiment, Figure 3 As shown, the touch structure includes a solder point 201. The mainboard 104 is electrically connected to one end of a wire 202 through the solder point 201. The other end of the wire 202 is electrically connected to a conductive spring 203. The conductive spring 203 is provided with a contactor for transmitting instructions to the mainboard 104. When the conductive spring 203 receives an electrical signal, the conductive spring 203 transmits the electrical signal to the sensing chip on the mainboard 104 through the mutual cooperation of the wire 202 and the solder point 201, providing conditions for the laser of the touch switch laser projector;
[0029] In one embodiment, Figure 3 and Figure 4 As shown, the contactor includes a metal window cover 204, which is fastened to the housing 101 by bolts. The metal window cover 204 fits the conductive spring 203, and a soft silicone pad 205 is provided inside the metal window cover 204. The skin of human tissue is a lossy electrolyte, equivalent to a conductive electrode. When a finger is placed on the metal window cover 204, it is equivalent to being placed in an energy overflow area called: fringe field, and will increase the conductive surface area of the capacitor system. Capacitive self-induction technology is used here: self-capacitance uses a pin and measures the capacitance between the pin and the power ground, that is, when a finger is placed on the sensor, the capacitance of the system will increase, so its voltage will also increase. The change in measured voltage can detect whether there is a finger touching. When the finger touches the middle area of the metal window cover 204 once, the laser emitter is turned on; when the finger touches the middle area of the metal window cover 204 again, the laser emitter is turned off. The opening and closing actions are completed in sequence;
[0030] In one embodiment, Figure 1As shown, the protection mechanism includes a rotating seat 301, which is provided at the upper end of 101. The rotating seat 301 is rotatably connected to the isolation component that provides isolation protection for the metal window cover 204. The rotating seat 301 provides a rotation condition to facilitate opening or closing the laser projection instrument window cover;
[0031] In one embodiment, Figure 1 As shown, the isolation assembly includes a protective cover 302, which is rotatably connected to a rotating base 301. A fixing element is provided at the lower end of the protective cover 302 to fix the protective cover 302. The protective cover 302 and the rotating base 301 cooperate with each other to facilitate the opening or closing of the laser projection instrument window cover. The protective cover 302 protects the metal window cover 204 from damage by collision, dust and water flow, thereby extending its service life.
[0032] In one embodiment, Figure 5 As shown, the fixing element includes a card block 304, the card block 304 is fixedly connected to the lower end of the protective cover 302, the lower end of the card block 304 is fixedly connected to the permanent magnet No. 1, and the upper end of 101 is provided with a fixing seat 303, and the fixing seat 303 is internally provided with a card slot 305 adapted to the card block 304, and the card slot 305 is internally provided with a permanent magnet No. 2 that attracts the permanent magnet No. 1. By inserting the card block 304 into the card slot 305, the card block 304 is fixed by the mutual attraction between the permanent magnet No. 1 and the permanent magnet No. 2, thereby facilitating the disassembly and assembly of the protective cover 302.
[0033] The above embodiment discloses a new type of laser line projector window cover, wherein when the laser line projector window cover needs to be opened, the rotating seat 301 provides rotation conditions, and the laser line projector window cover is opened or closed by the mutual cooperation of the protective cover 302 and the rotating seat 301. When the protective cover 302 is opened, by pressing the mechanical button 103, the mechanical button 103 transmits an instruction to the sensor chip on the main board 104, and the signal is transmitted to the main control of the line projector through the sensor chip, and the line projector laser starts to emit laser. When it is necessary to reduce the offset of the line projector laser, a finger touches the middle area of the metal window cover 204 once, increasing the capacitance of its system, and the voltage increases to detect whether there is a finger touch. At this time, the laser emitter is turned on. The finger touches the middle area of the metal window cover 204 again, and the laser emitter is turned off. By completing the opening and closing actions in sequence, the laser line projector window cover is closed at the end of the work. By inserting the card block 304 into the card slot 305, the card block 304 is fixed by the mutual attraction between the first permanent magnet and the second permanent magnet, and the closing work of the laser line projector window cover is completed.
[0034] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
