[0018] Figure 1 is a schematic structural diagram of the present invention; Figure 2 is a schematic diagram of the internal structure of the drive unit of the present invention; Figure 3 is a schematic structural diagram of the drive unit of the present invention; Figure 4 is a schematic structural diagram of the first hinge mechanism of the present invention.
[0019] As shown in the appended Figure 1 As shown in the figure, an electric tail wing assembly with infinitely adjustable opening angle includes a rear wing spoiler 1, a mounting base 2, a drive unit 3, a first hinge mechanism 4, and a second hinge structure 5. The housing of the drive unit 3 is installed on the bottom surface of the mounting base 2. The first hinge mechanism 4 and the second hinge structure 5 are respectively installed at both ends of the mounting base 2. Both ends of the drive shaft of the drive unit 3 are fixedly connected to the first hinge mechanism 4 and the second hinge structure 5 respectively. The first hinge mechanism 4 and the second hinge structure 5 are respectively fixedly connected to the rear wing spoiler 1.
[0020] As shown in the appended Figure 2 As shown in the figure, the drive unit 3 includes a housing 31, a motor 32, a first-stage worm 33, a first-stage worm gear 34, a second-stage worm 35, a second-stage worm gear 36, and a drive shaft 37. The motor 32 is fixed inside the housing 31. A first-stage worm 33 is fixed on the output shaft of the motor 32. The first-stage worm 33, the first-stage worm gear 34, the second-stage worm 35, the second-stage worm gear 36, and the drive shaft 37 are all rotatably connected inside the housing 31. The first-stage worm 33 meshes with the first-stage worm gear 34. The first-stage worm gear 34 and the second-stage worm 35 are coaxially fixed together. The second-stage worm 35 meshes with the second-stage worm gear 36. The second-stage worm gear 36 is sleeved and fixed on the drive shaft 37.
[0021] The housing 31 includes an upper shell and a lower shell. The upper shell and the lower shell are fixedly connected together by screws.
[0022] After the drive unit 3 is powered on, the output shaft of the motor 32 therein rotates. The output shaft drives the drive shaft 37 to rotate through the operation of a first-stage worm 33, a first-stage worm gear 34, a second-stage worm 35, and a second-stage worm gear 36. Due to the rigid fixation of the connecting pipe 44, the hinge shafts 42 on the first hinge mechanism 4 and the second hinge structure 5 on both sides will rotate synchronously with the drive shaft 37, driving the lifting of the link mechanism, and the tail wing spoiler 1 can be opened or closed.
[0023] A sensor 38 is fixed inside the housing 31, and a magnetic ring 39 is sleeved and fixed on the drive shaft 37. The magnetic ring 39 is located on one side of the sensor 38.
[0024] A motor magnetic ring 6 and a signal acquisition circuit board 7 are installed at the tail end of the motor 32.
[0025] As shown in the Figure 3 attachment, the housing 31 includes an upper housing and a lower housing, and the upper housing and the lower housing are fixedly connected together by screws.
[0026] Both the first hinge mechanism 4 and the second hinge structure 5 are composed of a bottom bracket 40, a hinge body 41, a hinge shaft 42, and a top bracket 43. The hinge body 41 is connected with the bottom bracket 40, the hinge shaft 42, and the top bracket 43. The top bracket 43 is fixedly connected to the tail wing spoiler 1, the hinge shaft 42 is fixedly connected to one end of the drive shaft 37, and the bottom bracket 40 is fixedly connected to the mounting base 2.
[0027] As shown in the Figure 4 attachment, the hinge body 41 includes a first connecting rod 45, a second connecting rod 46, a third connecting rod 47, and a fourth connecting rod 48. Both ends of the first connecting rod 45 are respectively hinged to the top bracket 43 and the bottom bracket 40. Both ends of the second connecting rod 46 are respectively hinged to the rod body of the first connecting rod 45 and one end of the third connecting rod 47. The other end of the third connecting rod 47 is fixed to one end of the hinge shaft 42. Both ends of the fourth connecting rod 48 are respectively hinged to the top bracket 43 and the bottom bracket 40. The hinge shaft 42 is connected to the third connecting rod 47 through interference fit, and synchronous movement is achieved between the two; the hinge shaft 42 is coupled with the top bracket 43 through a connecting rod assembly to realize the change of the height and angle of the electric tail wing; when the tail wing is in the fully open state, at this time the third connecting rod 47 contacts the bottom bracket, and the mechanical structure limits the position to realize the self-locking of the hinge mechanism, ensuring the opening height and angle of the tail wing, and under the action of external forces, the tail wing is not easy to shake, and further improving the support stability of the four-link mechanism for the tail wing plate. When the tail wing is in the closed state, the third connecting rod 47 will contact the bottom bracket again, and the hinge mechanism is self-locked again, ensuring that the tail wing can also withstand a certain external force in the closed state; in addition, an anti-collision gasket is installed on the bottom bracket, which can effectively reduce the noise generated when the third connecting rod 47 contacts the bottom bracket 40.
[0028] Both ends of the mounting base 2 are respectively provided with mounting sinks 21. The bottom bracket of the hinge body 41 is fixed in the mounting sink 21. The side of the mounting sink 21 is provided with a side hole 22 for passing through the hinge shaft 42. The bottom of the mounting sink 21 is fixedly connected with a drain pipe 23. The liquid stored in the mounting sink 21 can be discharged through the drain pipe 23.
[0029] The hinge shaft 42 is fixedly connected with one end of the drive shaft 37 through a connecting pipe 44.
[0030] The signal acquisition circuit board 7 is electrically connected to the wire harness assembly 30.
[0031] After the ECU issues an instruction, the motor 32 starts to rotate. A first-stage worm 33 is press-fitted on the output shaft of the motor 32 and will rotate synchronously with the motor 32. The first-stage worm 33 meshes with the first-stage worm gear 34. After the first-stage worm 33 rotates, it will drive the first-stage worm gear 34 to rotate. The first-stage worm gear 34 is press-fitted on the second-stage worm 35. After the first-stage worm gear 34 rotates, it will drive the second-stage worm 35 to rotate synchronously. The second-stage worm 35 meshes with the second-stage worm gear 36. After the second-stage worm 35 rotates, it will drive the second-stage worm gear 36 to rotate. The second-stage worm gear 36 is in interference fit with the drive shaft 37. After the second-stage worm gear 36 rotates, the drive shaft 37 will rotate synchronously. The magnetic ring 39 is in interference fit on the drive shaft 37. After the drive shaft 37 rotates, the magnetic ring 39 will also rotate synchronously. A motor magnetic ring 6 is integrated at the tail end of the motor 32, which corresponds to the signal acquisition circuit board 7 and can sense the change of the magnetic pole signal during the rotation of the motor 32, and output the rotation direction and number of turns of the motor 32 to the ECU. By recording and feedback the number of turns and direction of the motor 32 rotation, the precise control of the motor 32 rotation can be realized, and then the rotation angle and direction of the drive shaft 37 can be controlled, and finally the precise control of the opening angle of the tail wing can be realized, and the opening angle can be adjusted steplessly.
[0032] When the tail wing is fully opened or fully closed, the third link in the first hinge mechanism 4 and the second hinge structure 5 contacts the bottom bracket, realizing the self-locking of the first hinge mechanism 4 and the second hinge structure 5, ensuring the reliability and stability of the limit position. When in the stepless angle opening position in the middle, the first-stage worm 33, the first-stage worm gear 34, the second-stage worm 35, and the second-stage worm gear 36 inside the drive unit 3 realize the self-locking of the two-stage worm and worm gear transmission, ensuring the reliability and stability of any opening angle in the middle.
