[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 - Figure 5 As shown, an easy-to-install electronic tag structure includes an ETC electronic tag body 1 with a card slot 2 at one end. When in use, a bank card can be inserted into the card slot 2. Dedicated short-range communication is carried out between the ETC electronic tag body 1 and the microwave antenna on the ETC lane of the toll station, and computer networking technology is used to settle the payment with the bank backend.

[0023] A connection plate 3 is provided on the back of the ETC electronic tag body 1. An adhesive layer 4 is applied to the side of the connection plate 3 close to the ETC electronic tag body 1. The outer wall of the ETC electronic tag body 1 is bonded and fixed to the connection plate 3 via the adhesive layer 4.

[0024] Two clamping blocks 6 are symmetrically provided around the connecting disk 3. The clamping blocks 6 are fixedly connected to the connecting disk 3. A rubber belt 5 with an arc-shaped structure is fixedly connected to the side walls of the connecting disk 3 on both sides of the clamping blocks 6. A clamping plate 7 is provided below the connecting disk 3. A circular groove is provided on the upper surface of the clamping plate 7. The outer diameter of the rubber belt 5 is equal to the inner diameter of the circular groove.

[0025] A clamping ring 8 having an inner diameter smaller than that of the circular groove is fixedly connected to the top of the circular groove. An annular connecting groove 9 is formed between the clamping ring 8 and the bottom wall of the chuck 7. Two notches 10 are symmetrically provided on the upper surface of the clamping ring 8. Two clamping blocks 6 are arranged in alignment with the two notches 10, and the size of the clamping blocks 6 is adapted to the size of the inner cavity of the notches 10.

[0026] A disc-shaped buffer rubber pad 11 is provided on the outer wall of the chuck 7 away from the ETC electronic tag body 1. The buffer rubber pad 11 is fixedly connected to the outer wall of the chuck 7. Limiting bolts 12 that penetrate the chuck 7 are screwed on the outer walls on both sides of the circular groove. The adjacent ends of the two limiting bolts 12 extend into the annular connecting groove 9.

[0027] The side wall of the bottom end of the chuck 7 is fixedly connected to two symmetrically arranged connecting arms 13, and the free ends of the connecting arms 13 are fixed to the back shell of the car's central rearview mirror through a connecting piece. The connecting piece includes an ear plate 14 fixedly connected to the free end of the connecting arm 13, and a bolt 15 is passed through the ear plate 14. The bolt 15 passes through the ear plate 14 and is screwed to the back shell of the car's central rearview mirror.

[0028] It should be noted that this electronic tag is easy to install. When installing, first fit the connecting arms 13 fixed on both sides of the bottom of the chuck 7 to the back shell of the vehicle's central rearview mirror, then turn the bolts 15, screw the bolts 15 into the central rearview mirror shell, and then the chuck 7 can be fixed. Then the user uses the adhesive layer 4 to stick the back of the ETC electronic tag body 1 to the connecting disk 3, and rotates the connecting disk 3 to rotate the fixedly connected card block 6 on the connecting disk 3 to align with the notch 10 opened on the clamping ring 8. At this time, push it into the annular connecting groove 9. Move the connecting disc 3 so that the card block 6 passes through the notch 10 and is completely embedded in the annular connecting groove 9 together with the connecting disc 3. Finally, the user rotates the connecting disc 3 90 degrees through the ETC electronic tag body 1 so that the card block 6 is rotated to be misaligned with the notch 10. The ETC electronic tag body 1 can be clamped and fixed on the card disc 7 using the annular connecting groove 9. To prevent the connecting disc 3 from rotating in the annular connecting groove 9 due to bumps during driving, the user can screw the limit bolt 12 into the annular connecting groove 9 to tighten the rubber belt 5 fixed to the side of the connecting disc 3 through the limit bolt 12.

[0029] When the ETC electronic tag body 1 needs to be disassembled for inspection or battery replacement, the user can first screw the limit bolt 12 in the opposite direction to loosen the clamping of the rubber belt 5, and then use the ETC electronic tag body 1 to rotate the connecting disk 3 again, so that the blocks 6 on both sides of the connecting disk 3 are rotated to coincide with the position of the notch 10 opened on the clamping ring 8. At this time, the connecting disk 3 can be pulled outward with force to pull the connecting disk 3 out of the annular connecting groove 9, thus avoiding the problem that the existing ETC electronic tags are generally directly pasted and fixed on the front windshield of the vehicle, which is inconvenient to disassemble.

[0030] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
