Detailed Implementation

[0046] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0047] Please combine them together Figures 1 to 6 , Figure 12 and Figure 13This disclosure provides an infrared detector. The infrared detector includes a housing assembly 10, a main unit 20, a first magnetic chuck 30, a second magnetic chuck 40, and a base assembly 50. The housing assembly 10 has a mounting space 100. The housing assembly 10 is circumferentially provided with a detection hole 101, a first mounting hole 102, and a second mounting hole 103 communicating with the mounting space 100. The detection hole 101 and the first mounting hole 102 are respectively located on opposite sides of the housing assembly 10. The axial direction of the second mounting hole 103 is perpendicular to the axial direction of the detection hole 101. The main unit 20 is mounted in the mounting space 100 and is configured to perform infrared detection through the detection hole 101. The main unit 20 includes a human infrared sensor 21, a Fresnel lens 22, a circuit board 23, and a battery 24. The human infrared sensor 21 and the battery 24 are electrically connected through the circuit board 23. The battery 24 supplies power to the human infrared sensor 21 through the circuit board 23. The human infrared sensor 21 is mounted on the circuit board 23 and directly opposite the detection hole 101, and the Fresnel lens 22 is mounted on the detection hole 101. When the base assembly 50 is installed with the first mounting hole 102, the housing assembly 10 and the main unit 20 are horizontally mounted. When the base assembly 50 is installed with the second mounting hole 103 (as shown in the image), the infrared sensor 21 is mounted with the first mounting hole 102, and the infrared sensor 22 is mounted with the second mounting hole 103. Figures 1 to 3 As shown, the housing assembly 10 and the main unit 20 are installed vertically as a whole.

[0048] The first magnetic attractor 30 is disposed on the housing assembly 10 and covers the side of the first mounting hole 102 near the mounting space 100. The second magnetic attractor 40 is disposed on the housing assembly 10 and covers the side of the second mounting hole 103 near the mounting space 100. The base assembly 50 includes a base 51, a connecting post 52, and a third magnetic attractor 53. The first magnetic attractor 30, the second magnetic attractor 40, and the third magnetic attractor 53 can all be magnets. Alternatively, the first magnetic attractor 30 and the second magnetic attractor 40 can be magnetically attracted structures (such as iron plates), and the third magnetic attractor 53 can be a magnet. Alternatively, the first magnetic attractor 30 and the second magnetic attractor 40 can be magnets, and the third magnetic attractor 53 can be a magnetically attracted structure (such as an iron plate).

[0049] One end of the connecting post 52 is disposed on the base 51, and the other end has an insertion end 521. The third magnetic member 53 is installed on the insertion end 521. The insertion end 521 is configured to be inserted into the first mounting hole 102 so that the first magnetic member 30 and the third magnetic member 53 are magnetically connected, or inserted into the second mounting hole 103 so that the second magnetic member 40 and the third magnetic member 53 are magnetically connected.

[0050] Compared with related technologies, implementing the embodiments of this disclosure will have the following beneficial effects:

[0051] The infrared detector described above, in addition to possessing excellent infrared detection performance, also allows for convenient and rapid changes in detection direction without requiring the entire infrared detector to be disassembled. The infrared detector includes a housing assembly 10 with an installation space 100, a main unit 20 installed in the installation space 100, a first magnetic 30, a second magnetic 40, and a base assembly 50. The housing assembly 10 has a detection hole 101, a first mounting hole 102, and a second mounting hole 103 with its axis perpendicular to the axis of the detection hole 101, respectively. This arrangement of the first and second mounting holes 102 and 103 allows the housing assembly 10 and the main unit 20 to be installed in two ways (vertical and horizontal), thus facilitating changes in the detection direction. The first magnetic chuck 30 and the second magnetic chuck 40 are respectively disposed on the side of the first mounting hole 102 and the second mounting hole 103 near the mounting space 100, so that the original axial dimensions of the first mounting hole 102 and the second mounting hole 103 are not changed due to the placement of the first magnetic chuck 30 and the second magnetic chuck 40, and the original mounting dimensions remain unchanged. This results in a larger connection surface area between the housing assembly 10 and the base assembly 50, improving connection stability. The base assembly 50 includes a base 51, a connecting post 52, and a third magnetic chuck 53. One end of the connecting post 52 is disposed on the base 51, and the other end has an insertion end 521, on which the third magnetic chuck 53 is mounted. The insertion end 521 is configured to be inserted into the first mounting hole 102 to magnetically connect the first magnetic chuck 30 and the third magnetic chuck 53, or inserted into the second mounting hole 103 to magnetically connect the second magnetic chuck 40 and the third magnetic chuck 53. After the base 51 is connected and fixed to the mounting position, the first mounting hole 102 or the second mounting hole 103 can be inserted through the insertion end 521 and connected by magnetic attraction. This allows for convenient and quick changes in the detection direction without having to remove the entire infrared detector.

[0052] In the exemplary embodiments, please refer to Figures 5 to 7The insertion end 521 has a mounting groove 200, and the third magnetic member 53 is mounted in the mounting groove 200. The mounting groove 200 increases the connection surface area between the insertion end 521 and the third magnetic member 53, improving connection stability. The insertion end 521 has a small end 5211 and a large end 5212. The small end 5211 is located at the end of the large end 5212 away from the base 51. The mounting groove 200 passes through the small end 5211 and extends to the large end 5212, allowing the third magnetic member 53 to penetrate deeply into and connect with the large end 5212, improving connection stability and strength. This prevents the small end 5211 from being too thin in the circumferential dimension, which could easily cause it to break when the third magnetic member 53 is subjected to radial force. The small end 5211 matches the first mounting hole 102 and the second mounting hole 103. This improves the connection stability when the insertion end 521 is installed with the first mounting hole 102 and the second mounting hole 103, preventing the insertion end 521 from moving relative to the housing assembly 10 and causing connection instability. The axial and radial dimensions of the small end 5211 are consistent with the first mounting hole 102 and the second mounting hole 103.

[0053] In an exemplary embodiment, such as Figure 5 As shown, the third magnetic chuck 53 has a central through hole 300, and the connecting post 52 has a connecting hole 400 extending to the mounting groove 200. The third magnetic chuck 53 is connected to the insertion end 521 via a fastener 60 passing through the central through hole 300 and the connecting hole 400. The central through hole 300 ensures more even force distribution when the third magnetic chuck 53 is connected to the fastener 60. The connecting hole 400 allows the fastener 60 to penetrate deeply into the connecting post 52, increasing the connection surface area between the third magnetic chuck 53 and the connecting post 52 and improving connection stability. In this embodiment, the central through hole 300 is a countersunk hole, which can accommodate the head of the fastener 60, preventing it from hindering the magnetic connection between the third magnetic chuck 53 and the first magnetic chuck 30 and the second magnetic chuck 40.

[0054] In the exemplary embodiments, please refer to Figure 4 , Figure 6 , Figure 7 and Figure 9 The base 51 includes a core 511 and a cover 512. The core 511 includes a base plate 5111 and a core post 5112 disposed on one side of the base plate 5111. The base plate 5111 is configured to connect to the installation position. The base plate 5111 is provided with multiple base mounting holes 500. Threaded parts such as screws or bolts can connect the base plate 5111 to the installation position through the base mounting holes 500.

[0055] The core post 5112 is provided with a snap-fit ​​groove 600, through which the core post 5112 snaps into the connecting post 52, thus enabling quick assembly between the connecting post 52 and the core post 5112. The cover 512 covers the outer circumference of the base core 511, concealing the base mounting hole 500 and threaded parts such as screws or bolts, ensuring an overall aesthetic appearance. The cover 512 has a clearance hole 700, which is designed to avoid the connecting post 52, thus ensuring that the cover 512 does not obstruct the connection between the connecting post 52 and the housing assembly 10.

[0056] In the exemplary embodiments, please refer to Figure 4 and Figure 7 The core post 5112 has a hemispherical bottom 5113 and multiple claws 5114. The claws 5114 are axially spaced around the hemispherical bottom 5113, and the hemispherical bottom 5113 and the claws 5114 together form a locking groove 600. The sides of the hemispherical bottom 5113 and the claws 5114 facing the locking groove 600 are located on the same spherical surface. The connecting post 52 has a ball head 522 on the side away from the insertion end 521, and the ball head 522 is engaged with the locking groove 600. In this way, through the cooperation of the ball head 522 and the locking groove 600, the detection direction can be finely adjusted within a certain range, further improving the adaptability of the infrared detector to the detection environment. In this embodiment of the present disclosure, the claws 5114 are designed to utilize their elastic deformation capability to facilitate the engagement of the ball head 522 with the locking groove 600. Furthermore, after the claws 5114 are reset, they can increase the wrapping effect on the ball head 522, making the adjusted detection direction relatively stable.

[0057] In the exemplary embodiments, please refer to Figure 4 and Figure 6 The cover 512 abuts against the outer circumferential side of the claw 5114. In this way, the cover 512 can prevent the claw 5114 from moving away from the locking groove 600, further ensuring the wrapping of the claw 5114 around the ball head 522.

[0058] In the exemplary embodiments, please refer to Figures 7 to 10The base plate 5111 has multiple notches 801 and multiple slots 802 arranged circumferentially, with each notch 801 and slot 802 corresponding to the other along the circumference of the base plate 5111. The cover 512 has multiple snap-fit ​​blocks 5121 and pressure strips 5122, with each snap-fit ​​block 5121 corresponding to one of the notches 801. The snap-fit ​​blocks 5121 are designed to be inserted into the notches 801 one by one and can rotate with the cover 512 relative to the core 511, engaging with the corresponding slots 802 to clamp the base plate 5111 in conjunction with the pressure strips 5122. This arrangement of notches 801, slots 802, and snap-fit ​​blocks 5121 facilitates the rapid assembly of the base plate 5111 and the cover 512. During the installation of the infrared detector, the base plate 5111 can be connected to the installation position. The connecting post 52 passes through the clearance hole 700 and is inserted into the cover 512, where it engages with the snap-fit ​​groove 600. Subsequently, multiple snap-fit ​​blocks 5121 are inserted one-to-one into multiple notches 801. The cover 512 rotates relative to the base plate 5111, causing the multiple snap-fit ​​blocks 5121 to engage with their corresponding slots 802. The pressure strip 5122 works in conjunction with the snap-fit ​​blocks 5121 to clamp the base plate 5111, improving the connection stability between the base plate 5111 and the cover 512.

[0059] In the exemplary embodiments, please refer to Figure 8 and Figure 11 The locking block 5121 is provided with locking points 5123, and the base plate 5111 has locking grooves 803. The locking grooves 803 communicate with the slots 802, and the locking points 5123 and the locking grooves 803 are connected one-to-one. Through the cooperation of the locking points 5123 and the locking grooves 803, a prompt is generated indicating that the locking block 5121 has moved into place, and the locking block 5121 is relatively stable in the slots 802, making it difficult to separate or fall off. The locking points 5123 have arc surfaces, which facilitates the removal of the locking points 5123 from the locking grooves 803 when the external force driving the cover 512 reaches a certain value, thus facilitating the separation of the cover 512 and the base plate 5111.

[0060] In the exemplary embodiments, please refer to Figures 1 to 4 , Figure 12 and Figure 13The housing assembly 10 includes a front shell 11, an annular shell 12, and a bottom shell 13. The front shell 11, annular shell 12, and bottom shell 13 together form an installation space 100. A detection hole 101 is provided on the front shell 11, a first mounting hole 102 is provided on the bottom shell 13, and a second mounting hole 103 is provided on the annular shell 12. The bottom shell 13 is provided with a plurality of pillars 131, and the first magnetic accumulator 30 is provided with a plurality of insertion holes. The plurality of pillars 131 are inserted into the plurality of insertion holes one by one. The first magnetic accumulator 30 is riveted to the pillars 131 by heat fusion to improve the connection stability between the first magnetic accumulator 30 and the bottom shell 13. The annular housing 12 has a boss 121 with an insertion space 900. The insertion space 900 extends through the boss 121 on the side facing the face shell 11 and forms an opening 901. The second magnetic member 40 can be inserted into the insertion space 900 through the opening 901. The face shell 11 is connected to the annular housing 12 and can cover the opening 901 to press down the second magnetic member 40 and prevent it from shifting or loosening. The boss 121 and the insertion space 900 increase the connection area between the second magnetic member 40 and the annular housing 12, improving the connection stability between them. Furthermore, the face shell 11 can cover the opening 901 to ensure that the second magnetic member 40 is stably positioned in the insertion space 900.
