[0041] like Figure 1-4 A split sensing device is shown, which includes a sensing head and a mounting bracket 4.

[0042] The sensor head is the primary structure for performing the sensing function and comprises a housing 1, a sensor motherboard 2, and a power supply. The motherboard 2 and power supply are housed within the housing 1, which is provided with a socket 122. The mounting bracket is a wall-mounted structure connected to a building structure. In most cases, the mounting bracket 4 is secured to a wall, ceiling, pillar, or other structural element. The mounting bracket 4 is provided with a plug connector 441, which removably plugs into the socket 122.

[0043] In this embodiment, the mounting bracket 4 is fixed to the building structure, and the sensing head is simultaneously mounted on the mounting bracket 4. A plug slot 122 is provided on the housing 1 of the sensing head, and a plug connector 441 is provided on the mounting bracket 4. During assembly, the sensing head is detachably mounted on the mounting bracket 4 by utilizing the plug-in relationship between the plug connector 441 and the plug slot 122. This greatly simplifies the disassembly and installation process of the sensing head, making it very convenient to disassemble and install the sensing head even when it is installed at a high location, thereby reducing the maintenance difficulty of the split sensing device.

[0044] The housing 1 is provided with a plugging slot 122. Specifically, the housing 1 may be provided with an inwardly recessed plugging slot 122 on the bottom or back of the housing 1. Alternatively, the housing 1 may be provided with a protrusion 121 on the back, with the plugging slot 122 disposed on the protrusion 121, or the protrusion 121 may be provided with the aforementioned plugging slot 122. The protrusion 121 may be a fully protruding platform, or it may be a U-shaped protrusion 121, with the plugging slot 122 recessed from the opening of the U-shaped protrusion 121, and the plug connector 441 inserted through the U-shaped opening.

[0045] Furthermore, if Figure 4 As shown, a first positioning protrusion is provided on one or both sides of the insertion slot 122. A corresponding first recess is provided on one or both sides of the plug connector 441. When the plug connector 441 is inserted into the insertion slot 122, the first positioning protrusion engages with the first recess. This creates a stable connection between the plug connector 441 and the insertion slot 122, preventing the sensor head from automatically falling off during insertion.

[0046] In some embodiments of the induction head, such as Figures 2 to 4 As shown, the surface of the housing 1 is provided with an inwardly extending slide 123. The sensor head also includes a drawer 14, which is slidably disposed in the slide 123. The power source is a battery 3, which is detachably disposed on the drawer 14. As the drawer 14 slides into the housing 1, the battery 3 is electrically connected to the sensing mainboard 2. The battery 3 is detachably mounted on the drawer, and the battery 3 can be drawn in and out of the housing 1. When the battery 3 slides into the housing 1 with the drawer 14, the battery 3 is electrically connected to the sensing mainboard 2. Specifically, a positive conductive spring 15 and a negative conductive spring 16 are provided in the housing 1. After the battery 3 slides into the housing 1, the positive and negative electrodes of the battery 3 abut against the positive conductive spring 15 and the negative conductive spring 16, respectively. That is, the battery 3 can slide into or out of the housing 1 as the drawer 14 slides. In this way, the battery 3 can be very conveniently disassembled and maintained.

[0047] Furthermore, a second positioning protrusion is provided on one or both sides of the chute 123. A second recess is provided on the corresponding side or both sides of the drawer 14. When the drawer 14 slides into the chute 123, the second positioning protrusion engages with the second recess. This creates a stable connection between the drawer 14 and the chute 123, preventing the drawer 14 and the battery 3 from automatically falling out during use.

[0048] For the drawer 14, specifically, Figure 4 As shown, the portion of the drawer 14 that extends into the chute 123 is provided with a groove 141 for accommodating the battery 3. The bottom of the groove 141 passes through the drawer 14. The battery 3 is disposed in the groove 141. The drawer 14 uses the groove 141 to accommodate or support the battery 3 and to insert or remove the battery 3 from the housing 1.

[0049] In addition, inside the housing 1, as Figure 4As shown, a positive conductive spring clip 15 and a negative conductive spring clip 16 are respectively provided near the positive and negative poles of the battery 3. Furthermore, one end of the positive conductive spring clip 15 and one end of the negative conductive spring clip 16 are connected to the sensing mainboard 2, and the other ends of the positive conductive spring clip 15 and the other ends of the negative conductive spring clip 16 extend to positions near the positive and negative poles of the battery 3. The drawer 14 drives the battery 3 into a predetermined position within the housing 1, i.e., the position positioned by the aforementioned second positioning protrusion and second recess. The positive conductive spring clip 15 abuts the positive pole of the battery 3, and the negative conductive spring clip 16 abuts the negative pole of the battery 3.

[0050] In a more specific embodiment of the drawer 14, as Figure 4 As shown, the portion of the drawer 14 extending into the slide slot 123 has two elastic arms 142. The ends of the two elastic arms 142 are bent in opposite directions to surround the battery 3, and the groove 141 is located between the two elastic arms 142. The elastic arms 142 are particularly elastic and can clamp and fix the battery 3, thereby improving the stability of the battery 3 when assembled on the drawer 14.

[0051] In some embodiments of the housing 1, such as Figures 2 to 4 As shown, the housing 1 includes a front housing 11, a rear housing 12, and a sensor cover 13. The front housing 11 is buckled onto the rear housing 12, and the sensor cover 13 is disposed on the front housing 11. The sensor mainboard 2 is disposed within the rear housing 12. The front of the sensor mainboard 2 is provided with a sensor element 21, and the back of the sensor mainboard 2 is provided with a plurality of control switches 22. The sensor element 21 faces the sensor cover 13, and the control switches 22 face the rear housing 12.

[0052] The sensing mainboard 2 is arranged in the rear shell 12 , the front shell 11 is provided with an opening, the sensing cover 13 is arranged at the opening of the front shell 11 , and the front shell 11 is buckled on the rear shell 12 , thereby forming isolation protection for the sensing mainboard 2 .

[0053] In addition, the sensing cover 13 is a thin plate, a through hole is provided on the front shell 11, and the thin plate is arranged on the opening. The thin plate itself is thin in physical size, and the shielding, interference and reduction effects on the signal are weakened, that is, the intensity of the sensing signal after passing through the sensing cover 13 is enhanced.

[0054] In some embodiments of the rear housing 12, such as Figure 2As shown, the back cover 12 is provided with a plurality of control buttons 124. The control buttons 124 are arranged in a one-to-one correspondence with the control switches 22. The control buttons 124 abut against the control switches 22 to trigger the control switches 22 when pressed. The control buttons 124 include a switch button, a time button, a distance button, and a mode button. Among them, the switch button is used to turn on and off the split sensing device, the time button is used to set or adjust the built-in time of the split sensor, the distance button is used to control the working power of the sensor and thus adjust the sensing distance, and the mode button is used to adjust the sensor type, for example, it can switch between built-in sensing modes such as infrared sensing and radar sensing.

[0055] In some embodiments of the mounting bracket 4, such as Figure 4 As shown, the mounting bracket 4 includes a base 41, a swing arm 42, a locking member 43, and a connecting member 44. The first end of the swing arm 42 is swingably connected to the base 41. The locking member 43 is adjustably mounted on the base 41, abutting the first end of the swing arm 42. The connecting member 44 is mounted at the second end of the swing arm 42 and is provided with a plug connector 441. The swing arm 42 is connected to the sensor head via the connecting member 44. The swing arm 42 can swing on the base 41. This allows the sensor head to be adjusted in direction after assembly, improving the ease of adjustment of the sensor head.

[0056] Specifically, the first end of the swing rod 42 is a spherical structure, the base 41 wraps the spherical structure of the swing rod 42, and a groove is reserved on the base 41 for the swing rod 42 to swing.

[0057] Regarding the locking member 43 , specifically, the locking member 43 is disposed at the bottom of the base 41 , and the locking member 43 extends toward the first end of the swing rod 42 until it abuts against the first end of the swing rod 42 .

[0058] The locking member 43 is adjustably mounted on the base 41. Specifically, the locking member 43 may be threadedly connected to the base 41. Thus, the pressure exerted by the locking member 43 on the first end of the swinging rod 42 may be adjusted by rotating the locking member 43. Alternatively, the locking member 43 may be connected to the base 41 via screws, and the position of the locking member 43 may be adjusted by adjusting the screws, thereby adjusting the pressure exerted on the first end of the swinging rod 42.

[0059] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
