[0027] The plurality of electronic components 20 include a communication module 22, a positioning module 23 and a control module 24. The communication module 22, the positioning module 23 and the control module 24 are all arranged on the circuit board 21 and are all electrically connected to the circuit board 21 (the three can be arranged on the same circuit board 21 or on different circuit boards 21).

It should be noted that although the stacking arrangement of the plurality of circuit boards 21 will increase the thickness of the circuit module 2, the length and width of the circuit module 2 will be significantly reduced, so that the positioning device will not be a flat structure with a large size (such as a positioning device disclosed in patent CN219978532U, which is a circuit board with a large length and width in a housing, so that the positioning device is a flat structure with a large length and width), and improve the utilization rate of the component installation position on the circuit board 21, thereby realizing the miniaturization design of the positioning device.

This plug-in and matching method of the plug 4 and the socket 3 can realize the stable electrical connection and positioning of the two circuit boards 21, and is convenient for assembly.

Of course, in other embodiments, the plug 4 and the socket 3 may also be other forms of structures.

The first positioning column 5 and the second positioning column 6 are respectively arranged on the sides of the two circuit boards 21 close to each other (that is, the first positioning column 5 is arranged on the surface of the circuit board 21 to which it belongs close to the other circuit board 21, and the second positioning column 6 is also arranged on the surface of the circuit board 21 to which it belongs close to the other circuit board 21); a positioning hole 61 is provided on the second positioning column 6, and the first positioning column 5 is inserted into the positioning hole 61 of the second positioning column 6. By setting the first positioning column 5 and the second positioning column 6 to be plug-in-matched, on the one hand, the first positioning column 5 and the second positioning column 6 can assist in positioning the assembly between the circuit boards 21; on the other hand, the first positioning column 5 and the second positioning column 6 can assist in supporting and connecting the adjacent circuit boards 21.

[0032] like Figures 2 to 5 As shown, as an implementation mode, the number of the first positioning posts 5 and the number of the second positioning posts 6 are both multiple, the multiple first positioning posts 5 are arranged at intervals, the multiple second positioning posts 6 are arranged at intervals, and the multiple first positioning posts 5 correspond one-to-one to the multiple second positioning posts 6. In this embodiment, the multiple circuit boards 21 are all rectangular structures, the multiple first positioning posts 5 are respectively arranged at the four vertex positions on the circuit boards 21 to which they belong, and the multiple second positioning posts 6 are respectively arranged at the four vertex positions on the circuit boards 21 to which they belong.

[0033] like Figures 2 to 5 As shown, as an embodiment, multiple circuit boards 21 are all rectangular structures, the length and width dimensions of the multiple circuit boards 21 are the same (that is, the lengths and widths of the multiple circuit boards 21 are the same), and the edges of the multiple circuit boards 21 are flush, thereby facilitating assembly and being conducive to the miniaturized design of the positioning device.

[0034] like Figures 2 to 5As shown, as an embodiment, the number of circuit boards 21 is two (of course, in other embodiments, the number of circuit boards 21 can be more), and the two circuit boards 21 are respectively a first circuit board 211 and a second circuit board 212. According to the installation position of the electronic components 20, the multiple electronic components 20 are divided into a first type of electronic components 201, a second type of electronic components 202 and a third type of electronic components 203. The first type of electronic components 201 are arranged on the surface of the first circuit board 211 away from the second circuit board 212, the second type of electronic components 202 are arranged on the surface of the second circuit board 212 away from the first circuit board 211, the third type of electronic components 203 are arranged between the first circuit board 211 and the second circuit board 212, and the third type of electronic components 203 are arranged on the surface of the first circuit board 211 close to the second circuit board 212 and / or the surface of the second circuit board 212 close to the first circuit board 211. Such an arrangement can improve the utilization rate of the component installation position on the circuit board 21, which is conducive to the miniaturization design of the positioning device.

[0035] like Figures 2 to 6 As shown, as an embodiment, the third type electronic component 203 is arranged on the surface of the second circuit board 212 close to the first circuit board 211, and a metal heat sink 7 is arranged on the surface of the first circuit board 211 close to the second circuit board 212, and the metal heat sink 7 is in contact with the third type electronic component 203 (it should be noted that the metal heat sink 7 is not electrically connected to the first circuit board 211 and the third type electronic component 203). The material of the metal heat sink 7 can be a metal material with good thermal conductivity such as iron, aluminum, copper, etc. By setting the metal heat sink 7, on the one hand, since the heat dissipation capacity of the third type electronic component 203 is relatively poor (since the third type electronic component 203 is arranged between the first circuit board 211 and the second circuit board 212, it is more difficult to dissipate heat), the metal heat sink 7 can quickly guide the heat generated by the third type electronic component 203, thereby realizing the rapid heat dissipation of the third type electronic component 203; on the other hand, since the metal heat sink 7 is in contact with the third type electronic component 203, it can play a further auxiliary supporting role for the adjacent circuit board 21.

[0036] like Figure 5 and Figure 6As shown, as an embodiment, the metal heat sink 7 includes a flat plate portion 71 and a flange portion 72 formed by bending the edge of the flat plate portion 71, the flat plate portion 71 is a flat plate structure, the flat plate portion 71 is spaced apart from the first circuit board 211, the flange portion 72 is fixedly connected to the first circuit board 211, and the third type of electronic component 203 is in contact with the flat plate portion 71; a heat dissipation cavity 73 is formed between the flat plate portion 71 and the flange portion 72 (specifically, the heat dissipation cavity 73 is formed between the flat plate portion 71, the flange portion 72 and the first circuit board 211). Such a configuration can not only improve the heat dissipation efficiency of the metal heat sink 7, but also reduce the contact area between the metal heat sink 7 and the first circuit board 211, thereby reducing or avoiding the heat on the metal heat sink 7 from being conducted to the first circuit board 211.

[0037] like Figures 2 to 5 As shown, as an embodiment, the positioning device further includes a battery 26 disposed in the housing 1, the battery 26 is disposed on the outer surface of the outermost circuit board 21 (i.e., the surface of the outermost circuit board 21 away from other circuit boards 21), and the battery 26 is electrically connected to the outermost circuit board 21. Specifically, in this embodiment, the battery 26 is disposed on the surface of the first circuit board 211 away from the second circuit board 212, and the battery 26 is electrically connected to the first circuit board 211, that is, the battery 26 belongs to the first type of electronic component 201.

[0038] like Figures 2 to 5 As shown, as an embodiment, the plurality of electronic components 20 further include a SIM card slot 25 for inserting a SIM card, and the SIM card slot 25 is arranged on the surface of the first circuit board 211 away from the second circuit board 212.

That is, the SIM card slot 25 belongs to the first type of electronic component 201, the positioning module 23 belongs to the second type of electronic component 202, and the communication module 22 belongs to the third type of electronic component 203. Of course, in other embodiments, the above-mentioned electronic components 20 can also be arranged at other positions.

[0039] As an implementation method, the communication module 22 is a 4G network communication module, that is, it can communicate on the 4G network. The positioning module 23 is a GPS positioning module, which can perform GPS positioning. Of course, in other embodiments, the communication module 22 and the positioning module 23 can also be other types (for example, the communication module 22 is a 2G / 4G dual-frequency network communication module, and the positioning module 23 is a GPS / BD dual positioning module, that is, the positioning module 23 is compatible with GPS positioning and Beidou positioning).

[0040] like Figure 1and Figure 2 As shown, as an embodiment, the housing 1 is a rectangular parallelepiped structure, and the housing 1 includes a main housing 11 and a bottom cover 12 connected to each other, and the circuit module 2 is arranged in the main housing 11. The main housing 11 and the bottom cover 12 can be connected by snap connection, screw connection, etc.
