[0002] A positioning device is a device that uses satellite positioning and uploads the obtained positioning data to a server through a mobile communication module (GSM / GPRS network). A positioning device generally has a GPS positioning module and a mobile communication module. The GPS positioning module is used to obtain the location information of the positioning device, and then the mobile communication module transmits the location information obtained by the GPS positioning module to the cloud server. Users use their mobile terminal devices (such as mobile phones) to interact with the cloud server to obtain the location information of the positioning device.

[0003] The positioning devices currently on the market can generally meet the positioning needs, but they do not have a disassembly alarm function. For example, after the positioning device is installed on the device to be positioned (such as a vehicle), if the positioning device is removed and discarded, the user cannot know in time that the positioning device has been removed, resulting in the user being unable to find the device to be positioned in time through the positioning device, and ultimately causing the device to be lost.

[0033] The battery 25 is a rechargeable battery, and the battery 25 is electrically connected to the first circuit board 21, and the battery 25 is used to power the circuit module 2. The solar photovoltaic panel 3 is fixedly arranged on the outer wall of the housing 1 (specifically, it can be fixed by bolts), and the solar photovoltaic panel 3 is electrically connected to the first circuit board 21, and then electrically connected to the battery 25 through the first circuit board 21, and the solar photovoltaic panel 3 is used to charge the battery 25.

[0034] The positioning device provided by the embodiment of the utility model is provided with a solar photovoltaic panel 3 on the outer wall of the shell 1. The solar photovoltaic panel 3 can convert light energy into electrical energy after receiving light, and charge the battery 25, thereby improving the endurance of the positioning device (under sufficient light, there is no need to charge the battery 25 additionally, and charging the battery 25 with the solar photovoltaic panel 3 can meet the use requirements), greatly extending the use time of the battery 25 without increasing its capacity, eliminating the need for users to charge frequently, and can greatly reduce the risk of losing the positioning device due to exhaustion of power, thereby improving the user experience.

[0035] like Figure 2 and Figure 4As shown, as an embodiment, a mounting groove 11 is provided on the outer wall of the housing 1, and the size of the mounting groove 11 matches the size of the solar photovoltaic panel 3, and the solar photovoltaic panel 3 is fixedly arranged in the mounting groove 11. By providing the mounting groove 11, not only is it convenient to position and install the solar photovoltaic panel 3, but also after the solar photovoltaic panel 3 is installed in the mounting groove 11, its surface is flush with the outer wall of the housing 1, which can improve the aesthetics.

[0036] like Figures 1 to 4 As shown, as an embodiment, the shell 1, the mounting groove 11 and the solar photovoltaic panel 3 are all rectangular structures, and the length direction of the mounting groove 11 and the length direction of the solar photovoltaic panel 3 are parallel to the length direction of the shell 1, so as to adapt to the size structure of the solar photovoltaic panel 3, and can set a larger area of ​​solar photovoltaic panel 3 to improve the solar charging efficiency.

[0037] like Figures 4 to 6 and Figure 8 and Fig. 9 As shown, as an implementation mode, the solar photovoltaic panel 3 is electrically connected to the first circuit board 21 via a first cable (not shown), and a wiring channel (not numbered) for routing the first cable is provided on the shell wall of the shell 1.

[0038] Specifically, a through hole 12 is provided on the shell wall of the housing 1, and an annular protrusion 13 is provided on the inner wall of the housing 1, and the annular protrusion 13 is arranged around the periphery of the through hole 12. A wiring groove 14 connected to the through hole 12 is provided on the side wall of the annular protrusion 13, and the wiring channel includes the through hole 12 and the wiring groove 14, that is, one end of the first cable is electrically connected to the solar photovoltaic panel 3, and the other end of the first cable is electrically connected to the first circuit board 21 after passing through the through hole 12 and the wiring groove 14 in sequence. At the same time, the positioning device also includes an inner cover 15, and the inner cover 15 is fixedly connected to the annular protrusion 13 (specifically, it can be connected by screws) to cover the through hole 12, so as to prevent external rainwater, dust, etc. from entering the housing 1 through the through hole 12. By setting the wiring channel as the above-mentioned structure, not only can the sealing be improved, but also the wiring installation of the first cable can be facilitated (when installing, the first cable is wired first, and then the inner cover 15 is installed).

[0039] As an implementation method, the positioning device further includes a communication antenna (not shown) and a positioning antenna (not shown). The communication antenna is used to send and receive communication information, and the positioning antenna is used to receive positioning information. The communication antenna is electrically connected to the communication module 22, and the positioning antenna is electrically connected to the positioning module 23. In this embodiment, the communication antenna and the positioning antenna are both arranged outside the housing 1. Of course, in other embodiments, the communication antenna and the positioning antenna may also be arranged inside the housing 1. Figure 1As shown, an antenna interface (not shown) is provided at one end of the housing 1, through which the communication antenna and the positioning antenna are electrically connected to the communication module 22 and the positioning module 23. At the same time, a cover plate 6 is provided on the outer wall of the housing 1, and the cover plate 6 covers the antenna interface to play a sealing role.

[0040] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, as an embodiment, the circuit module 2 further includes a communication interface 26, which is arranged on one side of the housing 1 and close to the inner wall of the housing 1, and is electrically connected to the first circuit board 21. A plug hole 16 is provided on the housing wall of the housing 1 at a position corresponding to the communication interface 26, and the plug hole 16 penetrates the housing wall of the housing 1. The plug hole 16 and the antenna interface are respectively arranged on opposite sides of the housing 1, and the plug of an external device (such as a computer) can be connected to the communication interface 26 through the plug hole 16, so as to perform data interaction.

[0041] Specifically, the communication interface 26 includes a second circuit board 261 and a plurality of conductive pins 262 disposed on the second circuit board 261. The conductive pins 262 are located on the side of the second circuit board 261 close to the plug hole 16. The conductive pins 262 are electrically connected to the second circuit board 261, and the second circuit board 261 is electrically connected to the first circuit board 21. There are multiple plug holes 16, and the multiple plug holes 16 correspond to the multiple conductive pins 262 one by one. The multiple conductive pins 262 are used for external CAN interface, RS485 interface, RS232 interface, etc. By arranging the communication interface 26 in the housing 1, it is possible to avoid problems such as rust and poor air tightness caused by the exposure of the communication interface 26. At the same time, a sealing cover (not shown) is provided on the outer wall of the housing 1 at a position corresponding to the plug hole 16. The sealing cover can cover the plug hole 16 when it is not in use to improve the sealing.

[0042] like Figure 4 and Figure 7 As shown, as an embodiment, a battery compartment 17 for accommodating a battery 25 is provided in the housing 1, and the battery 25 is disposed in the battery compartment 17 (wherein, Figure 4 and Figure 7 The battery 25 is not shown in the figure to prevent the battery 25 from moving in the housing 1 and to isolate the battery 25 from other electronic components. There are multiple batteries 25 and battery compartments 17 (in this embodiment, there are two batteries 25 and two battery compartments 17), and the multiple battery compartments 17 are arranged in sequence along the length direction of the housing 1. The multiple batteries 25 are respectively arranged in the multiple battery compartments 17, so that the positioning device can be equipped with multiple large-capacity batteries to improve the endurance.

[0043] The first circuit board 21 and the communication interface 26 are respectively arranged on opposite sides of the battery compartment 17; the communication interface 26 and the first circuit board 21 are electrically connected through a second cable (not shown in the figure) (specifically, the second circuit board 261 and the first circuit board 21 are electrically connected through a second cable), and a gap 171 for routing the second cable is provided between the side wall of the battery compartment 17 and the inner wall of the shell 1 (that is, the second cable can be routed along the gap 171).

[0044] like Figure 4 , Figure 6 and Figure 7 As shown, as an embodiment, a card slot 18 is provided on opposite sides of the second circuit board 261 in the housing 1, and opposite ends of the second circuit board 261 are respectively inserted into the card slots 18 on opposite sides. A top block 5 is also provided in the housing 1, and opposite sides of the top block 5 are respectively abutted against the side wall of the battery compartment 17 and the surface of the second circuit board 261 away from the conductive pin 262. Through the clamping effect of the card slot 18 and the abutting effect of the top block 5, the second circuit board 261 can be fixed in the housing 1, which facilitates the installation of the communication interface 26.

[0045] like Figures 3 to 6 and Fig.11 and Fig.12As shown, as an embodiment, the circuit module 2 further includes a light sensor 27, which is disposed on the first circuit board 21 and electrically connected to the first circuit board 21, and the light sensor 27 is electrically connected to the control module 24. The housing 1 has a mounting surface 10 for fitting with a device to be positioned (not shown; the device to be positioned is, for example, a car, a bicycle, etc.) (i.e., when the housing 1 is mounted on the device to be positioned, the mounting surface 10 of the housing 1 fits with the device to be positioned), and a light hole 100 is provided on the housing wall of the housing 1 on one side close to the mounting surface 10, and the light hole 100 penetrates the housing wall of the housing 1, and the light sensor 27 is arranged corresponding to the light hole 100. The positioning device also includes a light shielding block 4, which is movably arranged in the light hole 100 (that is, the light shielding block 4 is not fixed in the light hole 100) to block the light hole 100, thereby preventing external light from passing through the light hole 100 to reach the light sensor 27; the light shielding block 4 is used to be fixed to the device to be positioned (that is, after the positioning device is installed, the light shielding block 4 is fixed on the device to be positioned). When the shell 1 is removed from the device to be positioned, the light shielding block 4 is removed from the light hole 100, and the light sensor 27 receives external light through the light hole 100, converts the optical signal into an electrical signal and transmits it to the control module 24, and the control module 24 controls the communication module 22 to send an alarm message (such as sending a text message or a phone notification) to the mobile terminal of the preset emergency contact (the mobile terminal of the emergency contact is, for example, a mobile phone, a computer, etc.). Specifically, the communication module 22 can first transmit the alarm message to the cloud platform, and then send the alarm message to the mobile terminal through the cloud platform, thereby realizing the disassembly alarm function of the positioning device.

[0046] Specifically, the principle of the disassembly alarm function of the positioning device is as follows: when the positioning device is installed on the device to be positioned, the housing 1 is fixed on the device to be positioned, the mounting surface 10 of the housing 1 fits with the device to be positioned, and the light shielding block 4 is located in the light hole 100, that is, the light hole 100 is blocked by the light shielding block 4. At this time, the external light cannot pass through the light hole 100 to reach the light sensor 27 (the light sensor 27 cannot receive the external light in the closed housing 1), and the positioning device does not send out an alarm message. When the housing 1 of the positioning device is removed from the device to be positioned by a stranger, since the light shielding block 4 is fixed on the device to be positioned, the light shielding block 4 will escape from the light hole 100, and the external light will pass through the light hole 100 to reach the light sensor 27. After receiving the external light, the light sensor 27 converts the optical signal into an electrical signal and transmits it to the control module 24. The control module 24 controls the communication module 22 to send an alarm message to the mobile terminal of the preset emergency contact. At this time, the user can receive the alarm message in time, thereby playing the disassembly alarm function.

[0047] In this embodiment, a light sensor 27 is provided, a light hole 100 is provided on the housing 1 at a position corresponding to the light sensor 27, and a light shielding block 4 is movably provided in the light hole 100. The light shielding block 4 cooperates with the light sensor 27 to realize the disassembly alarm function of the positioning device, so as to prevent the positioning device from being unable to track the position of the device to be located after being disassembled, thereby improving safety. Moreover, the disassembly alarm structure is cleverly designed, highly sensitive, and well concealed, and will not be easily cracked and invalidated.

[0048] like Fig.11 and Fig.12 As shown, as an embodiment, the circuit module 2 also includes an alarm device 28 disposed on the first circuit board 21, the alarm device 28 is electrically connected to the first circuit board 21, and the alarm device 28 is electrically connected to the control module 24; the control module 24 is used to control the alarm device 28 to send out corresponding alarm information after the housing 1 is disassembled, thereby playing a warning and deterrent role to the lawbreakers, and playing an alarm reminder role. The alarm device 28 can be an audible and visual alarm device, such as a speaker, which can send out specific sound alarm information (such as a buzzer).

[0049] As an implementation method, the shading block 4 is a magnetic block, and the shading block 4 can be adsorbed onto the device to be positioned by magnetic force (in this case, the device to be positioned is required to be made of ferromagnetic material). Of course, it is also possible to set an adhesive (not shown) on the shading block 4, and use the adhesive to adhere the shading block 4 to the device to be positioned. Of course, the shading block 4 can also be fixed to the device to be positioned by other means.

[0050] like Figures 3 to 6 As shown, as an embodiment, the light hole 100 is a circular hole, and the light shielding block 4 is a cylindrical structure, so that the light shielding block 4 can be more easily removed from the light hole 100 when the housing 1 is disassembled. At the same time, the diameter of the light shielding block 4 is slightly smaller than the diameter of the light hole 100, and the diameter of the light shielding block 4 is not less than 80% of the diameter of the light hole 100; on the one hand, it can avoid the light shielding block 4 from being too large and not easy to be removed from the light hole 100, and on the other hand, it can avoid the light shielding block 4 from being too small and not being able to play a good light shielding effect when the housing 1 is not disassembled, causing a false alarm. Of course, in other embodiments, the light hole 100 and the light shielding block 4 can also be other shapes and structures.

[0051] like Figures 3 to 6As shown, as an embodiment, the housing 1 includes a base 1A and a shell cover 1B connected to each other (the base 1A and the shell cover 1B can be fixedly connected by bolts), and the base 1A is used to be fixedly connected to the device to be positioned; the mounting surface 10 is provided on the side of the base 1A away from the shell cover 1B, and the light hole 100 is provided on the base 1A. Specifically, mounting portions 19 are provided at opposite ends of the base 1A, and the mounting portions 19 are used to be fixedly connected to the device to be positioned by bolts (not shown).

[0052] like Figures 3 to 6 As shown, as an embodiment, the solar photovoltaic panel 3 is fixedly arranged on the outer wall of the shell cover 1B away from the base 1A, so that after the shell 1 is installed on the device to be positioned, the solar photovoltaic panel 3 can better receive light. Specifically, the mounting groove 11 is arranged on the outer wall of the shell cover 1B away from the base 1A, and the solar photovoltaic panel 3 is fixedly arranged in the mounting groove 11.

[0053] As an implementation method, the control module 24 is a MCU micro control unit.

[0054] The positioning device provided by the embodiment of the utility model is provided with a light sensor 27, a light hole 100 is provided on the housing 1 at a position corresponding to the light sensor 27, and a light shielding block 4 is movably provided in the light hole 100, and the light shielding block 4 cooperates with the light sensor 27 to realize the disassembly alarm function of the positioning device, so as to prevent the positioning device from being unable to track the position of the device to be located after being disassembled, thereby improving safety. Moreover, the disassembly alarm structure is cleverly designed, highly sensitive, and well concealed, and will not be easily cracked and invalidated.

[0055] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
