[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0035] like Figures 1-5 The portable human body sensor shown includes a sensor head 1, a base 2, a first magnetic 3, a second magnetic 4, and a silicone cover 5. The sensor head 1 is movably mounted on the top of the base 2. The sensor head 1 contains a main board 6, which is equipped with a millimeter-wave radar for detecting the human body. The first magnetic 3 is located at the lower end of the sensor head 1. The second magnetic 4 is located at the upper end of the base 2 and is magnetically connected to the first magnetic 3. The silicone cover 5 is located at the bottom of the sensor head 1, and the top of the base 2 abuts against the silicone cover 5. It should be noted that the motherboard 6 is equipped with a wireless communication module (Bluetooth module or WIFI module) for wireless connection with external control devices, enabling users to remotely control the sensor. Therefore, the motherboard 6 has a button for pairing with external control devices, and the sensor head 1 has a pairing button 124 that can be pressed. When the sensor head 1 needs to be connected to the control device, the pairing button 124 must be pressed to pair the motherboard 6 with the control device. In addition, the motherboard 6 also has a power interface and an indicator light 62. The power interface is used to connect to an external power source, and the indicator light 62 can indicate the current working status of the sensor head 1. When adjustment is needed, the user only needs to manually change the contact area between the sensor head 1 and the base 2, which is flexible and convenient. The base 2 can be fixed to the wall by adhesive.

[0036] The beneficial effects of this utility model are as follows: by setting a first magnetic suction member 3 inside the sensing head 1 and a second magnetic suction member 4 inside the base 2, the first magnetic suction member 3 and the second magnetic suction member 4 are magnetically connected, thereby realizing the magnetic connection between the sensing head 1 and the base 2. This makes the connection between the sensing head 1 and the base 2 very convenient, and allows the position of the sensing head 1 to move flexibly around the base 2 within a certain range, greatly improving the flexibility of the sensing head 1. The setting of the silicone cover 5 can increase the friction between the sensing head 1 and the base 2, which is beneficial to improving the stability of the sensing head 1.

[0037] Please refer to Figure 3 and Figure 5In one possible implementation, the lower end of the sensor head 1 is provided with a receiving groove 121. The first magnetic attractor 3 is disposed at the bottom of the receiving groove 121, and the silicone cover 5 is also disposed in the receiving groove 121. The upper surface of the silicone cover 5 abuts against the lower surface of the first magnetic attractor 3. It should be noted that the receiving groove 121 can provide a mounting base for the first magnetic attractor 3 and the silicone cover 5. The inner wall of the receiving groove 121 is provided with a step, so that the receiving groove 121 is divided into two layers. The first magnetic attractor 3 is disposed in the inner layer, and the silicone cover 5 is disposed in the outer layer, so that the silicone cover 5 covers the first magnetic attractor 3 and seals the receiving groove 121, which helps to improve the overall stability of the sensor head 1.

[0038] Please refer to Figure 3 In one possible implementation, a first limiting protrusion 122 is provided on the inner wall of the receiving groove 121, and a first limiting groove 51 is provided on the outer wall of the silicone cover 5. The first limiting protrusion 122 extends into the first limiting groove 51. It should be noted that the cooperation between the first limiting protrusion 122 and the first limiting groove 51 can limit the silicone cover 5, prevent the silicone cover 5 from rotating, and improve the stability of the silicone cover 5. Furthermore, there are multiple first limiting protrusions 122 and first limiting grooves 51, with each first limiting protrusion 122 and each first limiting groove 51 corresponding one-to-one.

[0039] Specifically, in one possible implementation, the first magnetic attractor 3 is a magnet, and the second magnetic attractor 4 is an iron sheet; or, the first magnetic attractor 3 is an iron sheet, and the second magnetic attractor 4 is a magnet. It should be noted that in this embodiment, the first magnetic attractor 3 is a magnet, and the second magnetic attractor 4 is an iron sheet. The magnet can attract the iron sheet, thereby allowing the sensing head 1 to be attracted to the base 2. Furthermore, the area of ​​the lower surface of the magnet is smaller than the area of ​​the upper surface of the iron sheet, thus allowing the position of the magnet and the iron sheet to change, thereby altering the position of the sensing head 1 relative to the base 2.

[0040] Please refer to Figure 3 In one possible implementation, a second limiting groove 61 is provided on the side wall of the motherboard 6, and a second limiting protrusion 111 is provided on the inner wall of the sensing head 1. The second limiting protrusion 111 extends into the second limiting groove 61. It should be noted that the cooperation between the second limiting protrusion 111 and the second limiting groove 61 can limit the motherboard 6, prevent the motherboard 6 from rotating, and improve the stability of the motherboard 6.

[0041] Please refer to Figure 2 and Figure 5In one possible implementation, the top surface of the base 2 is an outwardly convex arc surface 211, and the bottom surface of the silicone cover 5 is an inwardly concave arc surface 52. The outwardly convex arc surface 211 and the inwardly concave arc surface 52 are adapted to fit together. The second magnetic suction member 4 is in the shape of an arc-shaped disc with a central outward convexity. The top surface of the second magnetic suction member 4 is adapted to fit together with the inner wall surface of the top of the base 2. It should be noted that the top of the base 2 is rounded, and the lower end of the silicone cover 5 has an arc-shaped groove, so that the top surface of the base 2 is an outwardly convex arc surface 211, and the bottom surface of the silicone cover 5 is an inwardly concave arc surface 52. In addition, the second magnetic suction member 4 is an arc-shaped disc with a central outward convexity, so that the top surface of the second magnetic suction member 4 is also an outwardly convex arc surface 211, thereby adapting and fitting the top surface of the second magnetic suction member 4 to the inner wall surface of the top of the base 2. In addition, the area of ​​the outwardly convex arc surface 211 is larger than the area of ​​the inwardly concave arc surface 52, so that the inwardly concave arc surface 52 can only contact a part of the outwardly convex arc surface 211. By simply rotating the sensing head 1 along the arc surface, the contact area between the inwardly concave arc surface 52 and the outwardly convex arc surface 211 can be changed, which can adjust the position of the sensing head 1, which is flexible and convenient, and helps to improve the smoothness of the sliding of the sensing head 1 relative to the base 2.

[0042] Please refer to Figure 3 In one possible implementation, the sensor head 1 includes a first upper shell 11 and a first lower shell 12, which are snap-fitted together. It should be noted that the inner wall of the first upper shell 11 is provided with a first snap-fit ​​portion 112, and the first lower shell 12 has a first elastic snap-fit ​​125. The first elastic snap-fit ​​125 engages with the first snap-fit ​​portion 112, and there are four of each of the first elastic snap-fit ​​125 and the first snap-fit ​​portion 112, which are evenly spaced and each first elastic snap-fit ​​125 engages with each first snap-fit ​​portion 112 in a one-to-one correspondence.

[0043] Please refer to Figure 3 In one possible implementation, the first lower shell 12 is provided with a first support post 123, and the motherboard 6 is disposed on the top of the first support post 123. It should be noted that there are three first support posts 123, which are arranged in a triangle to support three parts of the motherboard 6. In addition, the inner wall of the first upper shell 11 is also provided with a support rib 113. The top surface of the support rib 113 contacts the upper surface of the motherboard 6, and the top surface of the first support post 123 contacts the lower surface of the motherboard 6. The first support post 123 and the support rib 113 cooperate to clamp and fix the motherboard 6 from top to bottom, thereby improving the stability of the motherboard 6.

[0044] Please refer to Figure 4In one possible implementation, the base 2 includes a second upper shell 21 and a second lower shell 22, which are snap-fitted together. It should be noted that the inner wall of the second upper shell 21 is provided with a second snap-fit ​​portion 213, and the second lower shell 22 has a second elastic snap-fit ​​221. The second elastic snap-fit ​​221 engages with the second snap-fit ​​portion 213, and there are three of each type of snap-fit ​​and two snap-fit ​​portions 213, evenly spaced. Each second elastic snap-fit ​​221 engages with each second snap-fit ​​portion 213 in a one-to-one correspondence. Furthermore, a second support column 222 is provided at the center of the second lower shell 22, and the top surface of the second support column 222 abuts against the center of the second magnetic member 4 to support the second magnetic member 4, ensuring that the top surface of the second magnetic member 4 fits against the inner wall surface of the top of the second upper shell 21, which helps improve the stability of the second magnetic member 4.

[0045] Please refer to Figure 4 In one possible implementation, a third limiting protrusion 212 is provided on the inner wall of the second upper shell 21, and a third limiting groove 41 is provided on the second magnetic suction member 4, with the third limiting protrusion 212 extending into the third limiting groove 41. It should be noted that the cooperation between the third limiting protrusion 212 and the third limiting groove 41 can limit the movement of the second magnetic suction member 4, preventing it from rotating and improving its stability. Furthermore, there are multiple third limiting protrusions 212 and third limiting grooves 41, with each protrusion 212 and groove 41 corresponding one-to-one. Since the second magnetic suction member 4 is made of iron, it is very convenient to cut the third limiting groove 41 into it.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
