Subsequently, the rechargeable battery component 23 is installed on the lower housing 12. Then, the curved middle section of each engaging component 32 is respectively engaged with each engaging hole 211 on the main control board 21. At this time, the curved middle section of the engaging component 32... The middle section is compressed, and the end of the engaging member 32 away from the connecting fastener 31 moves in the mounting groove 311. By setting the engaging member 32, bidirectional transmission of power and data signals between the main control board 21 and the display control board 22 can be realized without the need for screws and nuts, avoiding increased contact resistance and unstable contact due to tightening torque, thus ensuring stable communication between the main control board 21 and the display control board 22. In addition, during the engaging process, it is necessary to ensure that the positions of each interface and functional module on the main control board 21 are accurate so as to facilitate subsequent connection and collaborative work with other components.

[0033] In this embodiment, the engagement hole 211 is implemented as a metal hole contact; in other embodiments, the engagement hole 211 may also be implemented as a planar metal contact.

[0034] Specifically, the main body 1 of the device also includes an anti-tamper switch 13 and an adhesive backing 14. The lower housing 12 has a first insertion hole 121 and the adhesive backing 14 has a second insertion hole 141. The first insertion hole 121 and the second insertion hole 141 are aligned. One end of the anti-tamper switch 13 is fixedly installed on the lower end face of the main control board 21.

The adhesive backing 14 is provided on the outer surface of the lower housing 12.

[0035] In this embodiment, finally, the user attaches the end of the adhesive 14 away from the lower housing 12 to the vehicle windshield, and the end of the anti-tamper switch 13 extending out of the lower housing 12 contacts the vehicle windshield. At this time, the anti-tamper switch 13 is in the closed state. Once the device body 1 falls off the vehicle windshield, or the device body 1 is manually removed from the vehicle windshield, the anti-tamper switch 13 is detached from the vehicle windshield and is in the open state. At this time, the device is in a disabled state, thereby realizing the anti-tamper function.

[0036] Specifically, the main body 1 of the device also includes a light-masking partition 15, which is installed on the upper housing 11. The upper housing 11 is made of a dark semi-transparent material. The light-masking partition 15 is provided with a plurality of light-transmitting holes 151 with preset patterns. The display control board 22 is provided with a programmable LED light source 221. The light-masking partition 15 is made of elastic foam material with a thickness of 1.0 to 1.5 mm. The aperture of the light-transmitting hole 151 is configured in a ratio of 1:1.2 to 1.5 with the LED light source 221.

[0037] In this embodiment, the worker installs the light-masking partition 15 onto the display control board 22. During installation, it is necessary to ensure that an optical isolation chamber is formed between the light-masking partition 15 and the display control board 22 to prevent light interference. In addition, by providing a light-transmitting hole 151 on the light-masking partition 15, the aperture of the light-transmitting hole 151 is configured in a ratio of 1:1.2 to 1.5 with the LED light source 221, the aperture design is optimized, and the light interference problem of multi-state display is solved.

[0038] Specifically, the internal circuit assembly 2 also includes a rechargeable battery component 23, which is installed on the lower housing 12 and is arranged in parallel with the main control board 21. Both the main control board 21 and the display control board 22 are connected to the rechargeable battery component 23 by circuit.

[0039] Specifically, the internal circuit assembly 2 also includes a solar charging panel 24, which is fixedly installed on the lower housing 12. The main control board 21 and the display control board 22 are both connected to the solar charging panel 24.

[0040] In this embodiment, during assembly, firstly, the worker welds the solar charging panel 24 to the lower housing 12, ensuring that the solar charging panel 24 fits tightly against the lower housing 12 to prevent shaking; then, the rechargeable battery component 23 is installed on the lower housing 12, ensuring that the rechargeable battery component 23 is arranged side by side with the main control board 21; by setting up the rechargeable battery component 23 and the solar charging panel 24, power is provided to the main control board 21 and the display control board 22, ensuring that the main control board 21 and the display control board 22 can work normally;

[0041] Specifically, the fixing structure 3 also includes a first buckle 33 and a second buckle 34. The first buckle 33 has a buckle groove 331, and the second buckle 34 is engaged with the buckle groove 331. Multiple first buckles 33 and multiple second buckles 34 are provided. Multiple first buckles 33 are installed at intervals on the edge of the upper housing 11, and multiple second buckles 34 are installed at intervals on the edge of the lower housing 12. Each first buckle 33 is aligned with each second buckle 34.

[0042] In this embodiment, the worker aligns the first buckle 33 at the edge of the upper housing 11 and the second buckle 34 at the edge of the lower housing 12 so that the second buckle 34 engages with the buckle groove 331, thereby ensuring that the upper housing 11 and the lower housing 12 are properly aligned and locked together.

[0043] The working principle of this utility model is as follows:

[0044] In the initial state, the lower housing 12 is provided with plastic parts; in the initial state, the lower housing 12 is provided with plastic parts; during assembly, firstly, the worker places the solar charging panel 24 on the plastic parts of the lower housing 12, and then uses equipment such as a high-temperature hot melt head to melt the plastic parts on the lower housing 12 by heating and pressurizing, so as to ensure that the solar charging panel 24 is tightly attached to the lower housing 12 and avoid shaking;

[0045] Subsequently, the rechargeable battery component 23 is installed on the lower housing 12, and the rechargeable battery component 23 is arranged side by side with the main control board 21. By setting the rechargeable battery component 23 and the solar charging panel 24, power is provided to the main control board 21 and the display control board 22, ensuring that the main control board 21 and the display control board 22 can work normally.

[0046] Next, the curved middle section of each engaging component 32 is engaged with each engaging hole 211 on the main control board 21. At this time, the curved middle section of the engaging component 32 is compressed, and the end of the engaging component 32 away from the connecting fastener 31 moves in the mounting groove 311. By setting the engaging components 32, bidirectional transmission of power and data signals between the main control board 21 and the display control board 22 can be realized without the need for screws and nuts, avoiding increased contact resistance and unstable contact due to tightening torque, thus ensuring stable communication between the main control board 21 and the display control board 22. In addition, during the engaging process, it is necessary to ensure that the positions of each interface and functional module on the main control board 21 are accurate so as to facilitate subsequent connection and collaborative work with other components.

[0047] Then, the workers install the light-masking partition 15 onto the display control board 22. During installation, it is necessary to ensure that an optical isolation chamber is formed between the light-masking partition 15 and the display control board 22 to prevent light interference. In addition, by setting the light-transmitting hole 151 on the light-masking partition 15, the aperture of the light-transmitting hole 151 is configured in a ratio of 1:1.2 to 1.5 with the LED light source 221, the aperture design is optimized, and the light interference problem of multi-state display is solved.

[0048] The worker then attaches the display control board 22, which is equipped with the light-masking partition 15, to the upper housing 11. Similarly, during the fixing process, it is necessary to ensure that the position of the display control board 22 is accurate so that the display control board 22 and the main control board 21 can make good electrical connection. In addition, by setting the upper housing 11 with a dark semi-transparent material, the LED light source 221 on the display control board 22 can pass through the light-transmitting hole 151 on the light-masking partition 15, thereby forming a clear display pattern on the outer surface of the upper housing 11, while preventing external light from interfering with the display effect.

[0049] After the light-blocking partition 15 is installed, the worker aligns the first buckle 33 at the edge of the upper housing 11 and the second buckle 34 at the edge of the lower housing 12 so that the second buckle 34 engages with the buckle groove 331, thereby ensuring that the upper housing 11 and the lower housing 12 are properly aligned and locked together.

[0050] Finally, the user attaches the end of the adhesive 14 away from the lower housing 12 to the vehicle windshield, and the end of the anti-tamper switch 13 extending out of the lower housing 12 contacts the vehicle windshield. At this time, the anti-tamper switch 13 is in the closed state. Once the device body 1 falls off the vehicle windshield, or the device body 1 is manually removed from the vehicle windshield, the anti-tamper switch 13 is detached from the vehicle windshield and is in the open state. At this time, the device is in a disabled state, thereby realizing the anti-tamper function.
