Specifically, the PCBA board 22 is responsible for receiving signals from the roadside device in the ETC system, processing signals, and controlling related operations of the ETC device, such as toll collection, recording vehicle information, etc.

[0046] As shown in Figures 1 to 2 , the PCBA assembly 20 includes a toggle 213 exposed outside the shell 10, and the toggle 213 is connected with the rotating shaft 21.

[0047] In some embodiments, the toggle 213 protrudes from the shell 10, and the person holds the toggle 213 to drive the rotating shaft 21 to rotate to adjust the angular position of the rotating shaft 21. It can be understood that the toggle 213 can be a lever or a knob structure, and the corresponding toggle 213 can be designed according to the specific shape of the shell 10 and the rotating shaft 21, and the embodiments of the present application will not be enumerated one by one.

[0048] In some embodiments, the position where the person holds the toggle 213 can also be provided with a non-slip pad or a structure with non-slip lines, to facilitate rotation after being held by the person.

[0049] As shown in Figure 3 and Figure 6 , the shell 10 is provided with at least one elastic clamping jaw 113, and the elastic clamping jaw 113 elastically abuts against the rotating shaft 21 to elastically retain the rotating shaft 21 at a specific position.

[0050] In some embodiments, the elastic clamping jaw 113 abuts against the rotating shaft 21 to generate friction and provide damping, so that after the rotating shaft 21 rotates, the rotating shaft 21 is prevented from rotating during vibration. When the rotating shaft 21 rotates, the rotating force applied by the person to the rotating shaft 21 is greater than the friction force, and the rotating shaft 21 rotates.

[0051] As shown in Figures 2 to 4 , a plurality of grooves 2120 are arranged circumferentially on the rotating shaft 21, and at least one elastic claw 113 is selectively matched with the plurality of grooves 2120.

[0052] In some embodiments, the elastic claw 113 abuts in the groove 2120, and it is understood that when a person applies a rotating force to the rotating shaft 21, the groove wall of the groove 2120 abuts against the elastic claw 113 to move to the outside of the groove 2120, the elastic claw 113 is separated from the groove 2120, and the rotating shaft 21 rotates by a certain angle. After rotation, the elastic claw 113 abuts in other grooves 2120. The damping and rotation angle control are realized, and each groove 2120 corresponds to a receiving angle.

[0053] In some embodiments, the deformation of the elastic claw 113 produces a click sound when rotating, which can prompt the change of the rotation angle.

[0054] The rotating shaft 21 includes a semi-cylindrical shell 211 and two damping wheels 212 arranged at two opposite ends of the semi-cylindrical shell 211, respectively. The surface of at least one damping wheel 212 is provided with a plurality of grooves 2120 in the circumferential direction, and at least one elastic claw 113 is selectively matched with the plurality of grooves 2120.

[0056] In some embodiments, the end of the elastic claw 113 is provided with an abutting block, the abutting block abuts in the groove 2120, and the elastic claw 113 abuts at a point thereof with the groove 2120, reducing the friction between the elastic claw 113 and the groove 2120.

[0057] In some embodiments, the abutting positions of the groove 2120 and the elastic claw 113 are both arc-shaped. However, the groove 2120 is in an inward arc structure, and the elastic claw 113 is in an outward arc structure. When the rotating shaft 21 rotates, it is convenient for the elastic claw 113 to separate from the groove 2120.

[0058] As shown in Figures 2 to 4 , the two damping wheels 212 are coaxial with the semi-cylindrical shell 211, respectively, and the diameters of the two damping wheels 212 are smaller than the outer diameter of the semi-cylindrical shell 211; the opening side of the semi-cylindrical shell 211 is provided with a buckle structure 2110, the PCBA board 22 is arranged in the semi-cylindrical shell 211, and is buckled by the buckle structure 2110.

[0059] In some embodiments, the damping wheel 212 rotates coaxially with the semi-cylindrical shell 211, avoiding deviation of the damping wheel 212 or the semi-cylindrical shell 211 after rotation.

[0060] In some embodiments, the buckle structure 2110 is in an inverted buckle shape, and the buckle structure 2110 mounts the PCBA board 22 on the semi-cylindrical shell 211. It is further understood that one side of the PCBA board 22 abuts against the end wall of the open end of the semi-cylindrical shell 211, and the other side of the PCBA board abuts against the buckle structure 2110, so as to ensure that the PCBA board 22 does not shake in the shell 10 after being mounted, avoiding damage caused by vibration.

[0061] As shown in Figures 5 to 7 The shell 10 includes an upper shell 11, and the upper shell 11 includes a top wall 111, two opposite first side walls 112, and at least one pair of elastic clamping jaws 113. The two opposite first side walls 112 are respectively mounted to the periphery of the top wall 111. The lower side edge of each first side wall 112 is concave upward to form a first mounting groove 1120 for mounting the end of the rotating shaft 21. The at least one pair of elastic clamping jaws 113 are arranged on the inner side of one of the two opposite first side walls 112 and correspond to the first mounting groove 1120.

[0062] The shell 10 includes a lower shell 12, and the lower shell 12 includes a bottom wall 121 and two opposite second side walls 122. The bottom wall 121 is adhesively mounted to the front windshield, center console, or handrail box of a vehicle, etc. The two opposite second side walls 122 are respectively mounted to the periphery of the bottom wall 121. The upper side edge of each second side wall 122 is concave downward to form a second mounting groove 1220 for mounting the end of the rotating shaft 21. The inner side of each of the two opposite second side walls 122 is mounted with a mounting seat 1221 for bearing the end of the rotating shaft 21, and the mounting seat 1221 is coaxial with the second mounting groove 1220.

[0063] In some embodiments, the upper shell 11 and the lower shell 12 are mounted by a buckle structure. The first mounting groove 1120 and the second mounting groove 1220 have the same shape as the damping wheel 212. The inner diameter of the first mounting groove 1120 is the same as the outer diameter of the damping wheel 212. The damping wheel 212 is rotatably mounted in the first mounting groove 1120 and the second mounting groove 1220.

[0064] In some embodiments, the upper shell 11 and the lower shell 12 are buckled together to form a sealed box body.

[0065] In some embodiments, the lower shell 12 is adhesively mounted in the front windshield, center console, or handrail box of a vehicle by double-sided adhesive tape, glue, or suction cups, etc. The fixing manner is not limited in the embodiments of the present application.

[0066] AsFigure 4 , Figure 6 and Figure 7 As shown, the first mounting groove 1120 has a first limiting groove 11201 circumferentially formed on the groove wall, and the second mounting groove 1220 has a second limiting groove 12201 circumferentially formed on the groove wall.

The limiting block 214 is slidably installed in the first limiting groove 11201 and the second limiting groove 12201 respectively. The other end of the first limiting groove 11201 is closed.

[0067] So that the limiting block 214 can slide from the first limiting groove 11201 to the second limiting groove 12201, or the limiting block 214 can slide from the first limiting groove 11201 to the second limiting groove 12201.

[0068] In some embodiments, the first limiting groove 11201 and the second limiting groove 12201 form a channel for the limiting block 214 to slide within the first limiting groove 11201 and the second limiting groove 12201. The closed end of the first limiting groove 11201 restricts the limiting block 214, and the closed end makes the circular channel formed by the first limiting groove 11201 and the second limiting groove 12201 not a closed structure, thus limiting the range of rotation of the limiting block 214 and the range of rotation of its rotating shaft 21, with a rotation angle of less than 360 degrees.
