Referring to fig. 1 to 9, in an embodiment of the present invention, the detecting apparatus 500 includes:
a circuit board 540, wherein an infrared emission head 550 and a receiving head 560 are arranged on the circuit board 540;
a bracket 530, wherein a first mounting hole 531 is formed on the bracket 530 corresponding to the transmitting head 550, and a second mounting hole 532 is formed on the bracket 530 corresponding to the receiving head 560; the first mounting hole 531 and the second mounting hole 532 are through holes, the transmitting head 550 is mounted in the first mounting hole 531, and the receiving head 560 is mounted in the second mounting hole 532.
Specifically, in the present embodiment, the circuit board 540 has a control circuit thereon, and the shape of the circuit board 540 may be various, such as a square, a long strip, a circle, an oval, and the like, and is not limited herein. The shapes of the infrared emitting head 550 and the receiving head 560 are not particularly limited, and the infrared emitting head 550 is exemplified by a long cylindrical shape, and the receiving head 560 is exemplified by a rectangular parallelepiped shape. The shape of the frame 530 can be many, such as a strip, a circle, a square, an oval, etc., and an elongated shape is used as an example. The first mounting holes 531 and the second mounting holes 532 are arranged along the length direction of the bracket 530 in a square manner, and the first mounting holes 531 and the second mounting holes 532 are both formed along the height direction of the bracket 530. First mounting hole 531 has a shape that fits infrared emission head 550 so that infrared emission head 550 can be mounted in first mounting hole 531. The shape of the second mounting hole 532 is adapted to the shape of the receiving head 560 so that the infrared receiving head 560 can be mounted in the second mounting hole 532.
There may be many infrared emitting heads 550, all arranged in a square along the length of the circuit board 540, or there may be many infrared receiving heads 560, and in this embodiment, one is taken as an example. The positional relationship between IR receiving head 560 and plurality of IR emitting heads 550 may be varied, for example, randomly arranged between IR emitting heads 550, taking the number of IR emitting heads 550 on either side of IR receiving head 560 as an example. Of course, the number of first mounting holes 531 on bracket 530 corresponds to the number of infrared emission heads 550, such that each infrared emission head 550 may be mounted into first mounting hole 531. Similarly, the number of the second mounting holes 532 on the bracket 530 is equivalent to the number of the ir receiving heads 560, so that each ir receiving head 560 can be mounted in the second mounting hole 532.
In this embodiment, through installing infrared emission head 550 in first mounting hole 531, install infrared receiving head 560 to second mounting hole 532 for the signal between infrared emission head 550 and the infrared receiving head 560 can not direct transmission, and must just can realize signal transmission through the reflection of external object, thereby has avoided the phenomenon of signal erroneous transfer to appear, has also avoided the phenomenon of maloperation to appear, thereby has improved the degree of accuracy that infrared detection device 500 detected.
In order to improve the accuracy of the infrared detection and avoid the interference of external light, the two ends of the bracket 530 are detachably connected to the two ends of the circuit board 540, and the circuit board 540 shields one end of the circuit board 540 facing the first mounting hole 531 and the second mounting hole 532. The board surface of the circuit board 540 faces the first mounting hole 531 and the second mounting hole 532, so that the board surface of the circuit board 540 shields the first mounting hole 531 and the second mounting hole 532 while the infrared emission head 550 and the infrared reception head 560 are mounted and mounted in the holes. So that light is difficult to enter the first and second mounting holes 531 and 532 from the circuit board 540 side, thereby preventing the infrared transmitting head 550 and the infrared receiving head 560 from being interfered by external light.
For example, the accuracy of infrared detection is improved, and interference of external light is avoided, a sealing rib 551 is arranged between the emission head 550 and the pins thereof, the sealing rib 551 is arranged along the circumferential direction of the emission head 550, and the sealing rib 551 is tightly fitted with the first mounting hole 531. Sealing ribs 551 are provided at an end of infrared emitting head 550 near the pins, and sealing ribs 551 are provided around the end of infrared emitting head 550. When infrared emission head 550 is installed in first mounting hole 531, the laminating of the inner wall of sealed muscle 551 and first mounting hole 531 prevents that light from getting into first mounting hole 531 from the clearance between infrared emission head 550 and the first mounting hole 531 to improve the precision of infrared emission head 550 transmission.
In order to improve the efficiency and accuracy of infrared detection, the number of the emission heads 550 is multiple, and a plurality of the emission heads 550 are arranged along the length direction of the circuit board 540; the receiving heads 560 are disposed in the middle of the circuit board 540 and between the receiving heads 560.

The radial arrangement of the first mounting holes 531 means that the plurality of first mounting holes 531 are arranged on the same circular arc, so that the hole depth directions of the adjacent first mounting holes 531 are different. When the emitters 550 are radially arranged, the detection signals emitted from the emitters 550 are curved to increase the detection range. In some embodiments, in order to better realize the radial arrangement of the first mounting holes 531, the bracket 530 is disposed in an arc shape, and a plurality of the first mounting holes 531 are arranged along the extending direction of the bracket 530.

The gasket 520 is disposed in a sheet shape, and the gasket 520 is attached to the bracket 530, so that light cannot enter from the first mounting hole 531 and the second mounting hole 532 through the hole of the circuit board 540, and thus the light is prevented from affecting the operation of the transmitting head 550 and the receiving head 560 from the front, and the accuracy of signal transmission and reception is effectively improved.
In some embodiments, in order to improve the installation stability of the gasket 520, the periphery of the side of the bracket 530 facing away from the circuit board 540 is provided with a limiting flange 535, the limiting flange 535 surrounds and forms an installation groove 536, and the gasket 520 is tightly matched with the installation groove 536. Limiting flange 535 is enclosed to form a ring shape, and the orifices of the first mounting hole 531 and the second mounting hole 532 are enclosed in the area of the limiting flange 535. The retention flange 535 defines the position of the gasket 520 when the gasket 520 is mounted to the bracket 530, thereby increasing the stability of the gasket 520.
In order to further improve the stability of the gasket 520, a limit pin 522 is disposed on one side of the gasket 520 facing the bracket 530, and a fixing hole 533 is disposed on the bracket 530 corresponding to the limit pin 522; the position-limiting foot 522 is tightly fitted with the fixing hole 533. The shape of the spacing leg 522 may be numerous, such as in a columnar configuration. The number of the limiting legs 522 may be plural, and for example, two limiting legs 522 are inserted into the fixing holes 533 of the bracket 530, so that the sealing gasket 520 is stably mounted on the bracket 530.
In order to improve the detection precision, the first mounting hole 531 faces away from one side of the circuit board 540, a limiting convex rib 534 is arranged on the periphery of the first mounting hole 531, and the avoiding hole 523 is sleeved on the limiting convex rib 534. Through the setting of protruding muscle, the sealing strip separation is avoided having elastic sealed pad 520 and covers the drill way of first mounting hole 531 and second mounting hole 532 with the protruding muscle outside first mounting hole 531 and second mounting hole 532 to make emission head 550 can effectually go out signal reflection, simultaneously, also guarantee that receiving head 560 can be more extensive received signal, thereby, be favorable to improving the precision. In addition, through the arrangement of the convex rib, the avoiding hole 523 is sleeved on the convex rib, so that the sealing gasket 520 is limited, and the stability of the sealing gasket 520 in the detection device 500 is improved.

Through the arrangement of the boss 521, the thickness of the gasket 520 at the boss 521 is greater than the thickness of the gasket 520 at other positions, so that the gasket 520 corresponding to the avoiding hole 523 can block the influence of light rays in a large range (along the depth direction of the hole). Meanwhile, the signal of the transmitting head 550 is prevented from being transmitted to the avoiding hole 523 corresponding to the receiving head 560 through the surface of the gasket 520, and then enters the receiving head 560. Thereby greatly reducing the possibility of signal false reception and improving the detection accuracy of the detection device 500.
In order to further improve the detection accuracy of the detection device 500, the detection device 500 further comprises a front shell 510 and a rear cover 570 adapted to the front shell 510; the front case 510 has a mounting cavity in which the bracket 530 and the circuit board 540 are mounted; the side walls facing the first mounting hole 531 and the second mounting hole 532 are light-transmissive; the rear cover 570 is fixedly connected to the front housing 510 to form a sealed installation cavity with the front housing 510.

There are many ways in which the bracket 530 and the circuit board 540 can be detachably mounted in the mounting cavity, such as snap-fit, screw-fit, adhesive-fit, etc. Through the cooperation of the front shell 510 and the rear cover 570, a sealed installation cavity is formed, so that moisture, light and air flow in the external environment cannot influence the work of the transmitting head 550 and the receiving head 560, thereby being beneficial to improving the working stability of the transmitting head 550 and the receiving head 560, and effectively improving the detection precision.
In order to further improve the detection precision, the side wall of the installation cavity, which is opposite to the first installation hole 531 and the second installation hole 532, is a light-transmitting decorative plate, and a light-transmitting groove is formed in the position, corresponding to the first installation hole 531 and the second installation hole 532, of the light-transmitting decorative plate. The color of the transparent decorative plate can be set according to more practical requirements, for example, when the detection device 500 is an infrared detection device 500, the color of the transparent decorative plate can be dark red. Through the setting of printing opacity groove for boss 521 on the sealed pad 520 can be installed in the printing opacity groove, makes sealed pad 520 shelter from the cell wall in printing opacity groove, thereby, avoids the signal to transmit along the printing opacity decorative board, and leads to the receiving head 560 mistake to receive. Therefore, the signal interference is effectively reduced, and the infrared detection precision is favorably improved.

The partition groove 511 is disposed on the inner side wall and/or the outer side wall of the light-transmitting decoration plate, and the partition groove 511 extends along the width direction of the light-transmitting decoration plate. Through the arrangement of the isolating groove 511, signals cannot be transmitted from the area corresponding to the transmitting head 550 to the area corresponding to the receiving head 560, so that the signal transmission of the signals in the light-transmitting decorative plate is isolated. Therefore, the signal is prevented from being transmitted along the transparent decorative plate, so that the receiving head 560 can not receive the signal by mistake. And then the signal interference is effectively reduced, and the accuracy of infrared detection is favorably improved.
