Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a TOF distance measurement and projection sensor. Background Art

[0002] As an advanced technology combination, TOF object detection and ranging + projection sensor has extremely wide applications in many fields such as dishwashers, refrigerators, and automobiles. The sensor mainly relies on the time-of-flight principle and can extremely accurately sense the distance between objects and devices. When consumers stretch their hands or feet close to the corresponding equipment, the sensor will detect the action at an astonishing speed and respond quickly to open the door. In dishwashers and refrigerators, this excellent technology greatly facilitates the user's door opening and closing operations. Users no longer need to directly touch the door with their hands, which not only keeps the equipment clean and hygienic, but also provides great convenience for users who hold items with both hands. In the automotive field, the sensor can also be used to achieve a convenient way to open the door, which not only improves the user experience, but also adds a strong sense of technology. The widespread application of this sensor has undoubtedly brought consumers a more intelligent, convenient and comfortable life experience.

[0003] However, the existing TOF inspection and ranging + projection sensor has some shortcomings in the application process. In most cases, it uses bolts to assist in installation. Although this method ensures the stability of the installation to a certain extent, subsequent disassembly and maintenance usually require the use of tools such as screwdrivers to assist in the operation, which makes the disassembly and assembly process more cumbersome and inconvenient. At the same time, during use, the projection lens on the surface of the projection sensor will accumulate dust over time. This dust will obviously have an adverse effect on the light transmittance of the lens, resulting in poor overall light transmittance, which in turn affects its inspection effect. It can be seen that the existing technology does have certain defects during use and urgently needs to be improved and optimized. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] First, in the present invention, by setting up a sensor body, the device can use the TOF object detection and ranging sensor and film projection during use. The TOF ranging function is used to detect changes in the user's waving or foot waving movements. Because the TOF laser is infrared light and the human eye cannot recognize the sensing range, the present invention adds film projection light, uses the lamp beads on the LED lamp board to illuminate the film with the image, and then refracts and transmits it through the lens, projecting the guide pattern into the sensing range through visible light, allowing the user to accurately identify the sensing range, and thus better and more effectively trigger the sensor.

When in use, the shell with the slide is inserted into the slot, the push plate is adjusted to drive the slide bar to move forward, so that the limit spring is stretched, and the limit plate and the limit block also move forward. When the shell is fully inserted into the installation slot, the push plate is released, the limit spring is reset, and the limit block is driven to insert into the card slot to complete the assembly of the mounting seat and the sensor body. Thereafter, the device is installed by screws in conjunction with the mounting holes on the mounting plate. When disassembly and maintenance are required, the push plate is adjusted forward again, and the push plate drives the slide plate to push the limit plate and the limit block out of the limit slot. The shell can be pulled out of the installation slot after losing the limit. Overall, the card installation mechanism makes the device easy to quickly disassemble and overhaul, improves the convenience of disassembly and maintenance during use, is very worthy of promotion and application, and brings great convenience to users.

[0018] Thirdly, in the present invention, the reasonably arranged dust-proof mechanism enables the sensor to play a powerful role in application. The second micro motor is started to drive the micro screw to rotate, driving the slider to slide on the inside of the guide rail, thereby assisting in driving the connecting rod and the scratch silicone plate to fit the outer surface of the lens. Then the first micro motor is started to drive the gear to rotate. Because the gear is engaged with the gear ring, the gear ring drives the slip ring to rotate, causing the guide rail and the connecting rod to rotate. The rotation of the connecting rod drives the scratch silicone plate to rotate around the lens, performing rotational scratch cleaning on the lens, effectively avoiding the lens from being blocked and maintaining its accuracy. When the sensor body needs to be used, the second micro motor is started to drive the micro screw to drive the slider upward, so that the scratch silicone plate leaves the lens to avoid obstruction. This adjustable design can be cleaned flexibly and quickly according to needs, without the need for manual wiping. It is more convenient when used especially when hidden inside the equipment, greatly improving the practicality and reliability of the sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The working principle of the present invention is as follows: by carefully configuring the sensor body 5, the present device has many advantages during use. Specifically, the TOF ranging function can work in synergy with the TOF object detection and ranging sensor 53 and the film projection film, and can extremely accurately detect changes in the user's waving or foot movements. Since the TOF laser is infrared light, the human eye cannot recognize its sensing range. Therefore, the present invention innovatively adds film projection light, using the lamp beads on the LED light board 52 to illuminate the film 55 with the image, and then refracting and transmitting through the lens 56, the guide pattern is projected in the form of visible light within the sensing range. In this way, the user can accurately identify the sensing range, and thus better and more effectively trigger the sensor, greatly improving the convenience and accuracy of the sensor.

[0035] By setting the card-mounting mechanism 6, the housing 51 with the slide plate 4 can be inserted into the interior of the slot 3 during use. During this process, the push plate 67 is adjusted to drive the slide bar 64 to move forward. At this time, the limit spring 63 is stretched, and the limit plate 65 and the limit block 66 also move forward. When the housing 51 is fully inserted into the interior of the installation slot 2, the limit push plate 67 is released, and the limit spring 63 is immediately reset, driving the limit plate 65 and the limit block 66 at its upper end to be inserted into the inner side of the card slot 62. At this time, the mounting base 1 and the sensor body 5 can be completed. After the assembly is completed, the device can be installed by screwing together the mounting holes 69 on the mounting plate 68. When it needs to be disassembled for maintenance, it is only necessary to adjust the push plate 67 to move forward. The push plate 67 drives the slide plate 4 to push the limit plate 65 and the limit block 66 to move forward. The limit block 66 can be separated from the limit groove. At this time, the shell 51 loses its limit and the shell 51 inside the mounting groove 2 can be pulled out. It can be seen that the device as a whole is easy to disassemble and repair quickly, which can further improve the convenience of disassembly and maintenance during the use of the device as a whole, and is very worthy of promotion and application.

[0036] By setting up the dustproof mechanism 7, the sensor can be operated by starting the second micro motor 732 during application. The second micro motor 732 drives the micro screw 733 to rotate. The rotation of the micro screw 733 can drive the slider 734 to slide on the inner side of the guide rail 731. The slider 734 slides on the inner side of the guide rail 731, and then it can assist in driving the connecting rod 735 and the scratching silicone plate 736 at its end to adhere to the outer surface of the lens 56. At this time, by starting the first micro motor 721 to run, the first micro motor 721 drives the gear 723 to rotate. Since the gear 723 and the gear ring 722 are engaged and connected, it can assist in driving the gear ring 722 to drive the slip ring 71 to rotate. The rotation of the slip ring 71 can drive the guide rail 731 and the connecting rod 735 at its top to rotate. The rotation of the connecting rod 735 can drive the scratch silicone plate 736 to rotate around the lens 56. At this time, the scratch silicone plate 736 can rotate and scratch the lens 56 to clean it, which can effectively prevent the lens 56 from being blocked and maintain the accuracy of the lens 56 for a long time. If the sensor body 5 needs to be used, the second micro motor 732 can be started to drive the micro screw 733 to drive the slider 734 to move upward, thereby causing the scratch silicone plate 736 to leave the lens 56. At this time, the lens 56 can be prevented from being blocked by the scratch silicone plate 736. This adjustable design can be cleaned flexibly and quickly according to specific needs, without the need for manual wiping, especially when it is hidden inside the equipment for use, which is more convenient, greatly improving the practicality and reliability of the sensor.
