[0031] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0032] Please refer to Figure 1-Figure 5, which is the first embodiment of this application, the ADAS camera device of the vehicle-mounted ETC disclosed in this utility model is now described. This utility model is composed of 6 parts, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a shell 1, an ADAS camera module 2, an ETC module 3, a power interface board 4, a voltage detection module 5 and a MOS control module 6. The interior of the shell 1 is a hollow structure. The ADAS camera module 2 is installed inside the shell 1. The ETC module 3 is detachably installed on the rear side wall of the shell 1. The ETC module 3 has a built-in departmental standard machine management protocol interface, which is used to receive remote unbinding instructions and perform security verification. The power interface board 4 is installed inside the shell 1. The power interface board 4 is used to power the ADAS camera module 2 and the ETC module 3. The power interface board 4 is connected to an external 12V power supply through a wiring harness. The voltage detection module 5 is used to detect the input voltage. The MOS control module 6 is electrically connected to the voltage detection module 5. The MOS control module 6 is used to control the power on and off.

[0033] In this embodiment, an ADAS camera module 2 and an ETC module 3 are integrated in the housing 1. The power interface board 4 is connected to the 12V main power supply of the ADAS camera module 2, and integrates a voltage detection module 5 and a MOS control module 6. After detecting a stable voltage input, it outputs an enable signal to the ETC module 3 to complete the startup control of the ETC. This design avoids the complex wiring of independent power supply, while supporting the on-demand activation and rapid replacement of the ETC function. When the ETC module 3 needs to be unbound, an unbinding instruction is sent through the Ministry of Transport certified departmental standard machine management platform. After receiving the instruction, the fusion device verifies the validity of the security certificate. If it matches, the vehicle binding information stored in the OBU is automatically cleared, and the unbinding success status is fed back to the platform.

[0034] By integrating the ETC module 3 into the housing 1 of the ADAS camera module 2 and sharing power with the power interface board 4, the space requirements associated with independent device installation are eliminated, reducing the number of devices and wiring complexity. The voltage detection module 5 intelligently controls ETC function activation, eliminating the redundant wiring associated with independent power supplies and reducing installation costs. The detachable design of the ETC module 3 provides flexibility for different vehicle models. The card insertion port of the ETC module 3 faces left, facilitating easy insertion and removal of the ETC card.

[0035] Preferably, the voltage detection module 5 and the MOS control module 6 are integrated inside the power interface board 4 .

[0036] Preferably, the ETC module 3 is a two-piece PCBA structure ETC module, which can be plugged in and replaced according to vehicle model requirements.

[0037] Preferably, the shell 1 is made by integrated injection molding and is adapted to the vehicle dashboard installation area; the shell 1 is made by integrated injection molding and is adapted to the optimal installation area of ​​the vehicle dashboard, ensuring the antenna signal transmission efficiency of the ETC module 3 and reducing the OBU signal poor problem caused by improper installation position.

[0038] like Figure 4 、 Figure 5 As shown, the outer wall of the housing 1 is provided with a slider 11, and the outer wall of the ETC module 3 is provided with a slide groove 31. The ETC module 3 is slidably connected to the rear wall of the housing 1 through the slide groove 31. In this embodiment, the shapes of the slider 11 and the slide groove 31 are as follows: Figure 4 As shown, by providing the slider 11 and the slide groove 31, the ETC module 3 can be easily disassembled and installed, which is convenient for later maintenance, upgrading or replacement.

[0039] like Figure 4 As shown, a POGO pin contact 111 is provided on the side wall of the slider 11. In this embodiment, by providing the POGO pin contact 111, while the power interface board 4 supplies power to the ETC module 3, it also supports hot plugging function, thereby improving the convenience of use.

[0040] like Figure 6 、 Figure 7 As shown, this is the second embodiment of the present application. The structure of the second embodiment is basically the same as that of the first embodiment. The difference is that the direction of the card insertion port of the ETC module 3 is different. In the second embodiment, the ETC card insertion port is directed upward, and the ETC card is vertically inserted into the ETC module 3 from above. The advantage of this arrangement is that the field of view is wider.

[0041] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
