Therefore, the following description should be understood as being broadly known to those skilled in the art and not as a limitation of the present invention.

[0054] Embodiment 1

The second fixing bracket 20 is used to form a buckle connection with the first fixing bracket 10 after the sensor 30 is clamped in the clamping position, so as to clamp and cover the sensor 30.

[0056] It can be seen from the above structure that when the sensor 30 needs to be installed, after the sensor 30 is snapped into the clamping position on the first fixed bracket 10, the second fixed bracket 20 is snapped with the first fixed bracket 10 to form a snap connection, so as to achieve an enveloping clamping of the sensor 30, that is, a full-scale clamping and locking connection, and then the first fixed bracket 10 is snapped onto the circuit board 60 of the device to be installed. The entire installation process can be carried out without the use of fasteners such as bolts, and the sensor 30 can be quickly installed with the circuit board 60, and it is convenient to disassemble.

[0057] In addition, it should be noted that the first fixing bracket 10 and the second fixing bracket 20 in this embodiment can also be formed by clamping the sensor 30 after the first fixing bracket 10 is first clamped on the circuit board 60 of the device to be installed. No specific limitation or elaboration is made here.

[0058] Further preferably, the first fixed bracket 10 includes: a base plate 101, an installation area 1010 arranged on the base plate 101 for accommodating the sensor 30, and a plurality of clamping members 103 arranged to enclose the installation area 1010 to form a clamping station to circumferentially limit the sensor 30.

[0059] Further preferably, the above-mentioned engaging members 103 are arranged in a rectangular shape, such as Figure 1 The illustrated engaging members 103a, 103b, 103c, 103d, etc. are arranged.

[0060] Further preferably, the snap connection and the insertion direction of the sensor 30 are perpendicular to each other.

[0061] Further preferably, the inner surface of the engaging member 103 has a protruding structure 1033 for engaging the sensor 30 .

[0062] Further preferably, the protruding structures 1033 are arranged along a direction perpendicular to the bottom plate 101 .

[0063] Further preferably, the proximal region where the protruding structure 1033 contacts the sensor 30 is a conical structure 10331 .

[0064] Further preferably, the above-mentioned snap-fitting parts 103 are two plate-like parts connected vertically, and the inner wall of each plate-like part is provided with a protruding structure 1033, so as to press the circumference of the sensor 30 and facilitate the insertion of the outer shell of the sensor 30 while limiting the position, thereby simplifying the processing technology and making the gap error between the plate-like part and the sensor 30 within a controllable range.

[0065] Further preferably, the above-mentioned snap-fitting part 103 is also provided with one or more ribs 1034 protruding away from the installation area 1010 and connected to the bottom plate 101, so as to enhance the fastness and structural strength of the snap-fitting part 103 and prevent the snap-fitting part 103 from being damaged when repeatedly installed and disassembled with the sensor 30.

[0066] Further preferably, the sensor installation structure further comprises: a snap-fitting member 105 disposed on the bottom plate 101 and used to form a snap-fitting connection with the second fixing bracket 20 .

[0067] Further preferably, there are at least two snap fasteners 105 which are arranged opposite to each other to enhance the firmness and stability of the snap connection.

[0069] Further preferably, the above-mentioned latching member 105 and the engaging member 103 are arranged in a manner of enclosing the installation area 1010 .

[0070] Further preferably, the installation area 1010 is a light-transmitting area, so that the sensor 30 can transmit and receive detection light through the light-transmitting area, thereby ensuring normal use of the sensor 30.

[0071] Further preferably, the base plate 101 is made of light-transmitting material.

[0072] Further preferably, the first fixing bracket 10 further includes: a clamping member disposed on the base plate 101 and used to be clamped into the circuit board 60, wherein the clamping direction of the clamping member is opposite to the insertion direction of the sensor 30.

Through this structure, the user can press the inclined surface 20162 outwards to disengage the clamping plate 2016 from the buckle 105, thereby facilitating disassembly without using additional tools to dock the plate and the buckle 105 for non-destructive disassembly.

[0086] In addition, in order to enable the snap-on housing 201 to apply a clamping force to the sensor 30 and prevent the snap-on plate 2016 and the snap member 105 from detaching from each other, the inclined surface 20162 is provided with a pressure column 20161 for pressing the snap-on housing 201 .

[0087] Further preferably, a deformation groove 2019 is provided on the snap-on housing 201 adjacent to the area pressed by the snap-on plate 2016 to prevent other parts in the area from being easily deformed and thereby clamping the side of the sensor 30 .

[0088] Further preferably, a snap-in groove is provided on the snap-in plate 2016, so that after the snap-in connection is formed, the snap-in plate 2016 can be flipped inwards, so that the snap-in shell 201 is snapped into the groove to form abutment, thereby enhancing the firmness of the connection.

[0089] Further preferably, a snap groove 20160 is provided on the snap-fit ​​plate 2016 for forming a snap connection with the snap-fit ​​member 103 .
