[0041] To make the purpose, technical solution and advantages of the present utility model clearer, the technical solution of this application will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of this application and the embodiments are detailed descriptions of the technical solution of this application, rather than limitations on the technical solution of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.

[0042] As Figures 1 - 19 shown, a corner sensor mounting structure includes a pedal arm 3, a connecting bracket 2 and a corner sensor 1. The pedal arm 3 is used for mounting a pedal; the connecting bracket 2 is mounted on the pedal arm 3 and is used to connect the pedal arm 3 and the corner sensor 1; the corner sensor 1 is mounted on the connecting bracket 2 and the center of the corner sensor 1 is concentric with the rotation center of the pedal arm 3, and the two move synchronously. The corner sensor 1 is used to monitor the movement state of the pedal in real time.

[0043] In some embodiments, as Figure 14 , Figure 15 shown, the corner sensor 1 is provided with a waist-shaped rotating shaft 1-2, and the pedal arm 3 is provided with a waist-shaped hole 3-1 that cooperates with the waist-shaped rotating shaft 1-2;

[0044] The waist-shaped rotating shaft 1-2 is mounted in the waist-shaped hole 3-1 and the waist-shaped rotating shaft 1-2 rotates synchronously with the pedal arm 3. The corner sensor 1 monitors the movement state of the pedal in real time through the rotation of the waist-shaped rotating shaft 1-2. The corner sensor 1 also rotates synchronously with the waist-shaped rotating shaft 1-2, avoiding the rotation error caused by structural errors and improving the signal output accuracy.

[0045] In some embodiments, as Figures 3 - 7As shown, a rotating bushing 12 is installed in the kidney-shaped hole 3-1. A rotating pin shaft 10 is installed in the rotating bushing 12. One end of the rotating pin shaft 10 is provided with a card slot 10-1. The kidney-shaped rotating shaft 1-2 of the angle sensor 1 is installed in the card slot 10-1. The rotating bushing 12 and the rotating pin shaft 10 move synchronously with the pedal arm 3. The pedal arm 3 rotates coaxially with the kidney-shaped rotating shaft 1-2. At the same time, the angle sensor 1 also rotates coaxially with the kidney-shaped rotating shaft 1-2, enabling the angle sensor 1 to accurately reflect the movement trajectory of the pedal arm 3 and output an accurate signal.

[0046] In some embodiments, as Figure 3 、 Figure 12 shown, the rotating bushing 12 and the rotating pin shaft 10 are connected and fixed by a fixed pin shaft 16 and a spring clip 17, ensuring the synchronous movement of the rotating bushing 12 and the rotating pin shaft 10.

[0047] In some embodiments, as Figures 8 - 11 shown, the connecting bracket 2 includes a side plate 4 installed on the rotating bushing 12 and a sealing plate 8 installed on the side plate 4. The angle sensor 1 is installed on the sealing plate 8. Fixing the angle sensor 1 together with the sealing plate 8 ensures that the angle sensor body does not rotate, and only the kidney-shaped rotating shaft 1-2 can rotate together with the rotating pin shaft 10 and the pedal arm 3.

[0048] In some embodiments, as Figure 1 、 Figure 2 shown, a return spring 5 is sleeved at one end of the rotating bushing 12. The two ends of the return spring 5 are respectively in contact with the pedal arm 3 and the connecting bracket 2. The return spring 5 is used to provide a return force for the pedal arm 3. When the pedal arm 3 is not subject to external force (when the brake pedal is released), the return spring 5 can return the pedal arm 3, the rotating pin shaft 10, and the kidney-shaped rotating shaft 1-2 of the angle sensor 1 to their original positions and stop signal output.

[0049] In the second aspect of the present invention, a new energy commercial vehicle is provided, and the angle sensor installation structure described above is installed on the new energy commercial vehicle.

[0050] During installation, first install the rotating bushing 12 in the kidney-shaped hole 3-1 of the pedal arm 3. The rotating bushing 12 is clamped in the kidney-shaped hole 3-1 of the pedal arm 3 through the retaining platform 12-1 and the platform 12-2 of the rotating bushing 12. Then install the bushing II 11 and the bushing III 14 at both ends of the rotating bushing 12. One end of the bushing II 11 is provided with a bushing U-shaped groove 11-1. Install a support pin shaft 13 in the bushing III 14. One end of the support pin shaft 13 is provided with a support pin shaft U-shaped groove 13-1, and the other end is provided with an internal thread 13-2;

[0051] Then, the side plates 4 of the connecting bracket 2 are correspondingly installed at both ends of the rotating bushing 12. Next, the sealing plate 8 of the connecting bracket 2 is fixed to the side plate 4 by means of the fixing nut 7 in cooperation with the welding bolts 18 on the side plate 4. Through holes corresponding to the inner holes of the bushing II 11 and the bushing III 14 are provided on the sealing plate 8. The bushing I 9 and the rotating pin shaft 10 are installed in the through holes on the sealing plate 8. A card slot 10-1 for connecting the angle sensor 1 is provided on the rotating pin shaft 10. A rotating pin shaft fixing pin hole 10-2 is also provided on the rotating pin shaft 10, and a rotating bushing fixing pin hole 12-3 is provided on the rotating bushing 12. The rotating pin shaft 10 and the rotating bushing 12 are connected and fixed by means of a fixing pin shaft 16 and a spring clip 17. A fixing bolt 15 is installed on the support pin shaft 13 inside the bushing III 14;

[0052] The angle sensor 1 is provided with an oval-shaped rotating shaft 1-2. Mounting holes 1-1 are provided on both sides of the angle sensor 1. The angle sensor 1 is installed on the sealing plate 8 by means of mounting bolts 6. The oval-shaped rotating shaft 1-2 of the angle sensor 1 is connected to the card slot 10-1 of the rotating pin shaft 10. A return spring 5 is sleeved at one end of the rotating bushing 12. Both ends of the return spring 5 are in contact with the pedal arm 3 and the connecting bracket 2 respectively, and are used to provide the return force for the pedal arm 3.

[0053] During use, the angle sensor 1 is fixed to the sealing plate 8 by means of the mounting bolts 6. The oval-shaped rotating shaft 1-2 of the angle sensor 1 is clamped into the card slot 10-1 of the rotating pin shaft 10. The rotating pin shaft 10 and the rotating bushing 12 are assembled together and are connected and fixed by means of a fixing pin shaft 16 and a spring clip 17. When the pedal arm 3 is stepped downwards, the pedal arm 3 moves downwards, and at the same time drives the rotating bushing 12 and the rotating pin shaft 10 to rotate together. The rotating pin shaft 10 simultaneously drives the oval-shaped rotating shaft 1-2 of the angle sensor 1 to rotate, so as to monitor the movement state of the pedal in real time. When the pedal arm 3 stops being stepped on, the pedal arm 3 can be pulled back to the initial state under the action of the return spring 5. When the pedal arm 3 returns, it will also drive the rotating pin shaft 10 and the rotating bushing 12 to return, thereby driving the angle sensor 1 to return, thus completing a cycle of pedal state monitoring.

[0054] In the angle sensor installation structure of the present utility model, the center of the angle sensor is concentric with the rotation center of the pedal arm, and the two move synchronously, without the need for redundant rocker connections, reducing the cost by more than 20%, and the control accuracy can be increased by more than 50%, and the failure rate can be reduced by more than 80%. The angle sensor is directly installed on the rotation axis of the pedal arm, without the need for redundant bracket connections, reducing the weight. The connecting bracket is directly assembled together with the pedal arm, etc., and can be first assembled into a pedal assembly module, and then the angle sensor is connected to the module, improving the assembly efficiency and assembly accuracy.

[0055] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features contained in other embodiments rather than other features, the combination of features of different embodiments also means that it is within the protection scope of the present utility model and forms different embodiments. For example, in the above embodiments, those skilled in the art can use them in a combined manner according to the known technical solutions and the technical problems to be solved by this application.
