[0025] As Figure 1 and Figure 2 shown, the throttle valve provided by the present utility model includes a throttle valve body 10, a throttle valve shaft 20, and a throttle valve flap 30. The throttle valve shaft 20 is movably inserted through the throttle valve body 10. The throttle valve flap 30 is arranged on the throttle valve shaft 20. On both sides of the throttle valve shaft 20, there are a cable assembly 40 and an electric drive assembly 50.

[0026] At both ends of the throttle valve shaft 20, there are respectively a first fork 21 and a second fork 22. The first fork 21 is located on one side of the throttle valve shaft 20 close to the cable assembly 40. The cable assembly 40 can drive the throttle valve shaft 20 to rotate through the first fork 21, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, thereby adjusting the opening degree of the throttle valve; the second fork 22 is located on one side of the throttle valve shaft 20 close to the electric drive assembly 50. The electric drive assembly 50 can drive the throttle valve shaft 20 to rotate through the second fork 22, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, thereby adjusting the opening degree of the throttle valve.

[0027] Figure 3 are the structural schematic diagrams of the cable assembly and the electric drive assembly in the embodiment of the present utility model Figure 1 ; Figure 4 are the structural schematic diagrams of the cable assembly and the electric drive assembly in the embodiment of the present utility model Figure 2 .

[0028] As Figure 3 and Figure 4 shown, the cable assembly 40 includes a cable pulley 41. The cable pulley 41 is movably sleeved on the throttle valve shaft 20. The cable pulley 41 is rotatably sleeved on the throttle valve shaft 20. There is a first protrusion 42 on the cable pulley 41. The first protrusion 42 abuts against the first fork 21, so that when the cable pulley 41 rotates, it can drive the throttle valve shaft 20 to rotate, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, thereby adjusting the opening degree of the throttle valve.

[0029] There is a cable groove 411 on the cable pulley 41. A cable is wound in the cable groove 411. One end of the cable is connected to the cable pulley 41. Stepping on the accelerator pedal to pull the cable can drive the cable pulley 41 to rotate, thereby completing the mechanical control of the throttle valve. The structure is simple and reliable, and the failure rate is low.

[0030] The cable assembly 40 further includes a cable bracket 43 which is arranged on the throttle body 10. The cable bracket 43 limits the routing of the cable, thus preventing deviation in the position and routing of the pulled cable, and improving the reliability of the structure.

[0031] The electric drive assembly 50 includes a housing 51, a drive motor 52 and an electric drive disk 53. The housing 51 is connected to the throttle body 10. The drive motor 52 is arranged on the housing 51. The drive motor 52 is connected to the electric drive disk 52. A second protrusion 54 is provided on the electric drive disk 53. The second protrusion 54 abuts against the second fork 22. When the drive motor 52 drives the electric drive disk 53 to rotate, the throttle shaft 20 can be driven to rotate through the second fork 22, driving the throttle valve piece 30 on the throttle shaft 20 to flip, thereby adjusting the opening degree of the throttle, and thus completing the electrical control of the throttle, with faster response and more precise control.

[0032] A connecting gear 55 is provided between the electric drive disk 53 and the drive motor 52. The connecting gear 55 is rotatably arranged on the housing 51. The connecting gear 55 is provided with an inner ring gear 551 and an outer ring gear 552. A motor gear 521 is sleeved on the motor shaft of the drive motor 52. The motor gear 521 meshes with the outer ring gear 552. A drive gear 531 is provided on the electric drive disk 53. The drive gear 531 is arranged at the edge of the electric drive disk 53. The drive gear 531 meshes with the inner ring gear 551, thereby connecting the electric drive disk 53 and the drive motor 52. The connecting gear 55 can further improve the response speed and control accuracy of the electric drive assembly 50.

[0033] A first torsion spring 11 is provided between the throttle body 10 and the cable assembly 40. One end of the first torsion spring 11 is connected to the throttle body 10, and the other end of the first torsion spring 11 is connected to the cable wheel 41. The first torsion spring 11 can keep the relative static state between the cable wheel 41 and the throttle body 10 when the cable assembly 40 is not working, and can drive the cable wheel 41 to reverse and reset after the cable assembly 40 finishes working, improving the reliability of the structure and extending the service life of the throttle; a second torsion spring 12 is provided between the throttle body 10 and the electric drive assembly 50. One end of the second torsion spring 12 is connected to the throttle body 10, and the other end of the second torsion spring 12 is connected to the electric drive disk 53. The second torsion spring 12 can keep the relative static state between the electric drive disk 53 and the throttle body 10 when the electric drive assembly 50 is not working, and can drive the electric drive disk 53 to reverse and reset after the electric drive assembly 50 finishes working, improving the reliability of the structure and extending the service life of the throttle.

[0034] A valve block 31 is provided on the throttle valve piece 30. The throttle valve piece 30 is circular and adapted to the inner wall of the throttle body 10. The valve block 31 is semi-circular and is arranged on the throttle valve piece 30, which can balance the flow of gas in the throttle body 10.

[0035] In the throttle valve provided by the present utility model, when the cable assembly 40 drives the cable wheel 41 to rotate by pulling the cable, the first protrusion 42 on the cable wheel 41 abuts against the first fork 21, thereby driving the throttle valve shaft 20 to rotate, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, and adjusting the opening degree of the throttle valve. During this process, the second protrusion 54 on the electric drive disk 53 separates from the second fork 22, and the electric drive disk 53 does not rotate with the rotation of the cable wheel 41, and the electric drive assembly 50 does not interfere with the cable assembly 40 during the operation of the cable assembly 40. When the drive motor 52 drives the electric drive disk 53 to rotate through the connecting gear 55, the second protrusion 54 on the electric drive disk 53 abuts against the second fork 22, thereby driving the throttle valve shaft 20 to rotate, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, and adjusting the opening degree of the throttle valve. During this process, the first protrusion 42 on the cable wheel 41 separates from the first fork 21, and the cable wheel 41 does not rotate with the rotation of the electric drive disk 53, and the cable assembly 40 does not interfere with the electric drive assembly 50 during the operation of the electric drive assembly 50. Therefore, in the throttle valve provided by the present utility model, the mechanical control and the electrical control are coordinated with each other, and there is no interference between the mechanical control and the electrical control, and different control methods can be adopted according to different driving modes of the vehicle, improving the engine performance.

[0036] Figure 5 is a structural schematic diagram of the cable assembly and the electric drive assembly in the embodiment of the present utility model Figure 3 。

[0037] As Figure 4 and Figure 5 shown, the throttle valve provided by the present utility model further includes a third torsion spring 13 and a fourth torsion spring 14. The third torsion spring 13 is sleeved on the throttle valve shaft 20 and is located inside the first torsion spring 11. One end of the third torsion spring 13 is connected to the throttle valve body 10, and the other end of the third torsion spring 13 is connected to the throttle valve shaft 20; the fourth torsion spring 14 is sleeved on the electric drive disk 53. One end of the fourth torsion spring 14 is connected to the electric drive disk 53, and the other end of the fourth torsion spring 14 is connected to the throttle valve shaft 20, and the return torque of the fourth torsion spring 14 is greater than the return torque of the third torsion spring 13. When the drive motor 52 rotates in the reverse direction, driving the electric drive disk 53 to rotate and compressing the fourth torsion spring 14, the torque of the fourth torsion spring 14 increases. At the same time, the second fork 22 moves away from the second boss 54, and the throttle valve flap 30 returns to the idle position under the action of the torsion spring 3; when the drive motor 52 is powered off, the throttle valve flap 30 returns to the emergency point state under the action of the fourth torsion spring 14, which can ensure that the throttle valve can still pass gas to maintain the operation of the vehicle when a failure occurs in the vehicle throttle valve, improving the reliability of the structure.

[0038] Functions and effects of the embodiment

[0039] The throttle valve provided by the present utility model includes a throttle valve body 10, a throttle valve shaft 20, and a throttle valve flap 30. The throttle valve shaft 20 is movably disposed through the throttle valve body 10. The throttle valve flap 30 is arranged on the throttle valve shaft 20. On both sides of the throttle valve shaft 20, there are a cable assembly 40 and an electric drive assembly 50. The cable assembly 40 and the electric drive assembly 50 can respectively complete the mechanical control and electrical control of the throttle valve, and the control processes do not interfere with each other, avoiding the problem of movement interference, and can adopt different control methods according to different driving modes of the vehicle, improving the engine performance.

[0040] In the throttle valve provided by the present utility model, when the cable assembly 40 drives the cable to drive the wire wheel 41 to rotate, the first protrusion 42 on the wire wheel 41 abuts against the first fork 21, thereby driving the throttle valve shaft 20 to rotate, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, and adjusting the opening degree of the throttle valve. During this process, the second protrusion 54 on the electric drive disk 53 separates from the second fork 22, and the electric drive disk 53 does not rotate with the rotation of the wire wheel 41, and the electric drive assembly 50 does not interfere with the cable assembly 40 during the working process of the cable assembly 40. When the drive motor 52 drives the electric drive disk 53 to rotate through the connecting gear 55, the second protrusion 54 on the electric drive disk 53 abuts against the second fork 22, thereby driving the throttle valve shaft 20 to rotate, driving the throttle valve flap 30 on the throttle valve shaft 20 to flip, and adjusting the opening degree of the throttle valve. During this process, the first protrusion 42 on the wire wheel 41 separates from the first fork 21, and the wire wheel 41 does not rotate with the rotation of the electric drive disk 53, and the cable assembly 40 does not interfere with the electric drive assembly 50 during the working process of the electric drive assembly 50. Therefore, in the throttle valve provided by the present utility model, the mechanical control and the electrical control are coordinated with each other, and do not interfere with each other, and can adopt different control methods according to different driving modes of the vehicle, improving the engine performance.
