Description

Technical Field

[0001] This application relates to the technical field of vehicle window lifting devices, specifically to a ripple motor, a window lifting mechanism, and a vehicle. Background Technology

[0002] With the development of the automotive industry, consumers have increasingly higher demands for the comfort, safety, and convenience of cars. One-touch power windows and anti-pinch functions have gradually been applied to various car models. Currently, there are two main control methods for anti-pinch window functions on the market: Hall effect anti-pinch and ripple effect anti-pinch, corresponding to Hall effect motors and ripple effect motors, respectively.

[0003] Hall effect motors integrate Hall sensors and window controllers, offering high stability and accuracy, but they are expensive, bulky, and heavy, making installation difficult. Ripple motors, on the other hand, do not include Hall sensors or window controllers, making them cheaper, smaller, and lighter. However, the carbon brushes and commutator in current ripple motors typically have surface contact. When the carbon brushes cross the commutator's electrode plates, a significant resistance change occurs. This causes glitches and jitter in the current ripple waveform obtained by the car's controller, resulting in poor control accuracy and stability. This can lead to problems such as accidental window pinch-off or failure to close. Utility Model Content

[0004] In view of the above, it is necessary to propose a ripple motor, a window lifting mechanism, and a vehicle to improve the control accuracy and stability of the ripple motor and reduce the probability of accidental window pinching and failure to close.

[0005] This application provides a ripple motor, including a first housing, a stator, a rotor, a shaft, a commutator, and a brush assembly. The stator and the rotor are both disposed within the first housing. The shaft is connected to the rotor and is coaxially arranged. The commutator is sleeved on the shaft and located on one side of the rotor. The brush assembly includes an assembly, an elastic element, and balls. The assembly and the balls are both made of conductive material. The assembly is spaced apart from the circumferential side of the commutator. The balls are rotatably disposed at the end of the assembly near the commutator and rotatably abut against the circumferential side of the commutator. The elastic element is disposed at the end of the assembly away from the balls and is configured to apply pressure toward the commutator to the assembly.

[0006] In some embodiments, the end of the assembly near the commutator has a storage groove that conforms to the shape of the ball bearing, and the ball bearing is rotatably disposed in the storage groove.

[0007] In some embodiments, the brush assembly further includes a cover member disposed at one end of the assembly near the commutator. The cover member has a through hole that is directly opposite to and communicates with the receiving groove. The portion of the through hole near the receiving groove is contoured to the ball bearing. The diameter of the portion of the through hole away from the receiving groove is smaller than the diameter of the ball bearing. The ball bearing passes through the through hole and protrudes from the side of the cover member away from the assembly.

[0008] In some embodiments, the ripple motor further includes a support member disposed in the first housing. The support member has a support portion disposed opposite to the peripheral side surface of the commutator. The support portion has a guide groove extending radially toward the commutator. The assembly is slidably disposed in the guide groove. The elastic member is disposed in the guide groove. The two ends of the elastic member are respectively connected to the end of the assembly away from the ball and the bottom of the guide groove.

[0009] In some embodiments, the fitting has a limiting protrusion on the side opposite to the ball, and the elastic element is sleeved on the limiting protrusion.

[0010] In some embodiments, the ripple motor further includes a second housing, a drive shaft, and a transmission assembly. The second housing is disposed within the first housing, the rotating shaft extends into the second housing, the drive shaft passes through the second housing, and the extension direction of the drive shaft is perpendicular to the extension direction of the rotating shaft. The transmission assembly is connected to the rotating shaft and the drive shaft, and the transmission assembly is configured to drive the drive shaft to rotate under the drive of the rotating shaft.

[0011] In some embodiments, the transmission assembly includes a worm gear and a worm, the worm being connected to one end of the shaft extending into the second housing and coaxially disposed with the shaft, and the worm gear being sleeved on the drive shaft and meshing with the worm.

[0012] In some embodiments, the ripple motor further includes a drive gear, which is sleeved on the drive shaft and located outside the second housing.

[0013] The ripple motor in this embodiment uses a ball bearing that rolls against the circumferential surface of the commutator, and an elastic element that presses the ball bearing against the circumferential surface of the commutator via an assembly. This ensures that the ball bearing and the circumferential surface of the commutator are always in point contact. When the ball bearing moves to the junction of the electrode plate and the insulating plate of the commutator, the ball bearing can quickly detach from the electrode plate, and the circuit state quickly changes from closed to open. Similarly, when the ball bearing moves to the junction of the insulating plate and the electrode plate, the ball bearing can quickly detach from the insulating plate, and the circuit state quickly changes from closed to closed. Therefore, the waveform of the current ripple generated by the ripple motor in this application will not exhibit glitches or jitter, thereby improving the control accuracy and stability of the ripple motor and reducing the probability of accidental window pinching or failure to close. Furthermore, the ripple motor in this embodiment has a simple structure, low cost, and small size.

[0014] This application also provides a glass lifting mechanism, including the ripple motor described above.

[0015] The glass lifting mechanism of this application improves the accuracy and stability of driving the window glass to rise and fall by setting a ripple motor, reduces the probability of the window accidentally being pinched or unable to close, and reduces costs.

[0016] This application also provides a vehicle including the window lifting mechanism described above.

[0017] The vehicle in this embodiment improves the accuracy and stability of driving the window glass up and down by setting a window lifting mechanism including the above-mentioned ripple motor, and reduces the probability of the window accidentally being pinched or unable to close.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0033] Please see Figure 1 and Figure 10 This application provides a ripple motor 1 for driving the window glass 200 of a vehicle 1000 to rise and fall. The vehicle 1000 can be a gasoline-powered vehicle, an electric vehicle, a hybrid vehicle, etc., which is obviously not a limitation of this application.

[0034] Please see Figure 1 and Figure 2 In this embodiment, the ripple motor 1 includes a first housing 10, a stator 21, a rotor 22, a shaft 23, a commutator 30, and a brush assembly 40. The stator 21 and rotor 22 are both housed within the first housing 10. The shaft 23 is connected to the rotor 22 and coaxially arranged with it. The commutator 30 is sleeved on the shaft 23 and located on one side of the rotor 22. The brush assembly 40 includes a mounting part 41, balls 42, and an elastic element 43. Both the mounting part 41 and the balls 42 are made of conductive material. The mounting part 41 is spaced apart from the peripheral side of the commutator 30. The balls 42 roll along the end of the mounting part 41 near the commutator 30 and roll against the peripheral side of the commutator 30. The elastic element 43 can be a spring, located at the end of the mounting part 41 away from the balls 42, and is configured to apply pressure to the mounting part 41 toward the commutator 30.

[0035] Please refer to the following: Figure 3 In this embodiment, the commutator 30 includes a fixing member 31, multiple electrode plates 32, and multiple insulating plates 33. The fixing member 31 is sleeved on the rotating shaft 23. The multiple electrode plates 32 and multiple insulating plates 33 are all spaced apart along the circumference of the fixing member 31 on its peripheral sidewall. An insulating plate 33 is provided between every two electrode plates 32, isolating two adjacent electrode plates 32. The insulating plate 33 can be made of bakelite (phenolic plastic) to prevent two adjacent electrode plates 32 from being electrically connected. The fixing member 31 and the multiple electrode plates 32 can be an integral structure or a separate structure; this embodiment does not specifically limit this.

[0036] Please refer to the following: Figure 6 Because the carbon brushes (not shown) of the existing ripple motor (not shown) have surface contact with the commutator 30, when the carbon brush crosses the electrode plate 32 of the commutator 30, it cannot quickly transfer all contact points to the insulating plate 33. Similarly, when the carbon brush crosses the insulating plate 33 of the commutator 30, it cannot quickly transfer all contact points to the electrode plate 32. This results in a large resistance change, leading to large current fluctuations. Furthermore, the circuit state cannot quickly switch between open and closed circuits, thus causing problems such as... Figure 6 The waveform diagram of the current ripple shown is from... Figure 6 It is known that the waveform of current ripple will exhibit phenomena such as glitches and jitter, resulting in poor control accuracy and stability of existing ripple motors.

[0037] Please refer to the following: Figure 7 In this embodiment of the ripple motor 1, the ball bearing 42 rolls against the circumferential surface of the commutator 30, and the elastic element 43, through the mounting fitting 41, elastically presses the ball bearing 42 against the circumferential surface of the commutator 30. Therefore, the ball bearing 42 and the circumferential surface of the commutator 30 are always in point contact. When the ball bearing 42 moves to the junction of the electrode plate 32 and the insulating plate 33 of the commutator 30, the ball bearing 42 can quickly detach from the electrode plate 32, and the circuit state quickly changes from closed to open. When the ball bearing 42 moves to the junction of the insulating plate 33 and the electrode plate 32, the ball bearing 42 can also quickly detach from the insulating plate 33, and the circuit state quickly changes from open to closed. Therefore, the ripple motor 1 of this application produces the following... Figure 7 The waveform of the current ripple shown in the figure does not exhibit glitches, jitter, or other phenomena, thereby improving the control accuracy and stability of the ripple motor 1 and reducing the probability of accidental window pinching and failure to close.

[0038] Please refer to it again. Figure 3 In this embodiment, the end of the assembly 41 near the commutator 30 is provided with a storage groove 411 that is similar in shape to the ball 42, and the ball 42 is rolled in the storage groove 411.

[0039] When the ball bearing 42 rolls in only one direction, it is prone to wear and deformation in that direction, gradually changing from a spherical shape to an ellipsoidal shape. This causes the contact between the ball bearing 42 and the commutator 30 to gradually change from point contact to line contact or surface contact, thus affecting the control accuracy and stability of the ripple motor 1. By setting up the receiving groove 411 and rolling the ball bearing 42 in the receiving groove 411, when the ball bearing 42 rolls and abuts against the peripheral side of the commutator 30, it can roll in all directions. The wear area of ​​the ball bearing 42 is relatively uniform, thus ensuring that the contact between the ball bearing 42 and the commutator 30 is always point contact, which helps to improve the control accuracy and stability of the ripple motor 1.

[0040] In this embodiment, the ball bearing 42 is made of carbon steel, which not only ensures the conductivity of the ball bearing 42, but also improves the wear resistance and service life of the ball bearing 42.

[0041] Please refer to the following: Figure 4 In another embodiment, the brush assembly 40 further includes a cover 44, which is disposed at one end of the assembly 41 near the commutator 30. The cover 44 is detachably connected to the assembly 41. The cover 44 has a through hole 441 that is directly opposite to and communicates with the receiving groove 411. The portion of the through hole 441 near the receiving groove 411 is contoured to the ball 42. The diameter of the portion of the through hole 441 away from the receiving groove 411 is smaller than the diameter of the ball 42. The ball 42 passes through the through hole 441 and protrudes from the side of the cover 44 away from the assembly 41.

[0042] By providing a cover 44 and having a through hole 441 in it, the ball bearing 42 can roll and abut against the circumferential side of the commutator 30, while preventing the ball bearing 42 from falling out of the receiving groove 411 and causing the ripple motor 1 to fail, thus improving the stability of the ripple motor 1. In addition, since the cover 44 is detachably connected to the assembly 41, it is convenient to replace the ball bearing 42.

[0043] Please refer to the following: Figure 5 In this embodiment, the ripple motor 1 further includes a support member 50, which is disposed in the first housing 10. The support member 50 has a support portion 51 disposed opposite to the peripheral side of the commutator 30. The support portion 51 has a guide groove 511 extending radially toward the commutator 30. The mounting part 41 is slidably disposed in the guide groove 511. An elastic member 43 is disposed in the guide groove 511. The two ends of the elastic member 43 are respectively connected to the end of the mounting part 41 away from the ball 42 and the bottom of the guide groove 511.

[0044] By setting up a support member 50 and opening a guide groove 511 on the support member 50 to guide the movement direction of the assembly 41, the probability of the assembly 41 causing the ball 42 to deviate and wobble can be effectively reduced, thereby ensuring that the ball 42 rolls and abuts against the circumferential wall of the commutator 30 along a fixed path, thereby improving the control accuracy and stability of the ripple motor 1.

[0045] In some other embodiments, a guide rail (not shown) extending radially toward the commutator 30 may also be provided inside the first housing 10. The guide rail is connected to the first housing 10, and the fitting 41 is slidably disposed on the guide rail. The two ends of the elastic member 43 are respectively connected to the end of the fitting 41 away from the ball 42 and the inner wall of the first housing 10. This can also reduce the probability of the fitting 41 causing the ball 42 to deviate and shake. This application embodiment does not specifically limit this.

[0046] Please refer to it again. Figure 3 In this embodiment, the side of the assembly 41 facing away from the ball 42 is provided with a limiting protrusion 412, and the elastic member 43 is sleeved on the limiting protrusion 412. The limiting protrusion 412 can limit the elastic member 43 from shifting relative to the assembly 41, reduce the probability of the elastic member 43 disengaging from the assembly 41, and improve the accuracy of the elastic member 43 pressing the assembly 41 and the ball 42.

[0047] In other embodiments, the elastic element 43 and the assembly 41 can also be connected by welding, bolting or other methods, and this application does not specifically limit this.

[0048] In this embodiment, the brush assembly 40 also includes a wire (not shown), one end of which is connected to the mounting part 41 or the elastic element 43, and the other end of which is connected to the controller of the vehicle 1000 (not shown), so that the controller can obtain the waveform of the current ripple according to the current change.

[0049] Please refer to it again. Figure 1 and Figure 2 In this embodiment, the ripple motor 1 further includes a second housing 60, a drive shaft 70, and a transmission assembly 80. The second housing 60 is disposed within the first housing 10, the rotating shaft 23 extends into the second housing 60, the drive shaft 70 passes through the second housing 60, and the extension direction of the drive shaft 70 is perpendicular to the extension direction of the rotating shaft 23. The transmission assembly 80 is connected to the rotating shaft 23 and the drive shaft 70, and the transmission assembly 80 is configured to drive the drive shaft 70 to rotate under the drive of the rotating shaft 23.

[0050] Since the extension direction of the drive shaft 70 is perpendicular to the extension direction of the rotating shaft 23, it is convenient to arrange the rotating shaft 23 and the drive shaft 70 in a smaller space, thereby facilitating the miniaturization of the ripple motor 1.

[0051] In this embodiment, the transmission assembly 80 includes a worm gear 81 and a worm 82. The worm 82 is connected to one end of the rotating shaft 23 extending into the second housing 60 and is coaxially arranged with the rotating shaft 23. The worm gear 81 is sleeved on the drive shaft 70 and meshes with the worm 82. Due to the high transmission accuracy of the worm gear 81 and the worm 82, the accuracy of the rotating shaft 23 driving the drive shaft 70 to rotate through the transmission assembly 80 is improved, thereby improving the output accuracy of the ripple motor 1. In addition, by reasonably setting the number of teeth of the worm gear 81 and the worm 82, the transmission assembly 80 can also realize a speed reduction function.

[0052] In this embodiment, the ripple motor 1 further includes a drive gear 90, which is sleeved on the drive shaft 70 and located outside the second housing 60. By providing the drive gear 90, it is convenient for the ripple motor 1 to be driven and connected to the structure that needs to be driven.

[0053] In one embodiment, the drive gear 90, drive shaft 70, and worm gear 81 can also be an integral structure, which helps to reduce the probability of relative movement between the drive shaft 70 and the drive gear 90 and worm gear 81.

[0054] In summary, the ripple motor 1 of this application embodiment achieves point contact between the ball bearing 42 and the commutator 30 by rolling contact, and by using an elastic member 43 to elastically press the ball bearing 42 against the commutator 30 via the mounting part 41. When the ball bearing 42 moves to the junction of the electrode plate 32 and the insulating plate 33 of the commutator 30, the ball bearing 42 can quickly detach from the electrode plate 32, and the circuit state quickly changes from closed to open. Similarly, when the ball bearing 42 moves to the junction of the insulating plate 33 and the electrode plate 32, the ball bearing 42 can quickly detach from the insulating plate 33, and the circuit state quickly changes from open to closed. Therefore, the waveform of the current ripple generated by the ripple motor 1 of this application will not exhibit glitches or jitter, thereby improving the control accuracy and stability of the ripple motor 1 and reducing the probability of accidental window pinching and failure to close. In addition, the ripple motor 1 of this application embodiment has a simple structure, low cost, and small size.

[0055] Please refer to the following: Figure 8 and Figure 9 This application embodiment also provides a glass lifting mechanism 100, including the ripple motor 1 as described above, which is used to drive the window glass 200 to lift.

[0056] The glass lifting mechanism 100 of this application embodiment improves the accuracy and stability of driving the window glass 200 to rise and fall by setting the ripple motor 1, reduces the probability of the window being accidentally pinched or unable to close, and reduces costs.

[0057] In this embodiment, the glass lifting mechanism 100 further includes a support plate 101, a winding reel (not shown), multiple transmission wheels 102, a transmission belt 103, and a lifting member 104. The support plate 101 is connected to the door 300 of the vehicle 1000. The support plate 101 has a slide rail 1011 extending in a vertical direction. The lifting member 104 is slidably connected to the slide rail 1011 and is used to install the window glass 200. A ripple motor 1 is mounted on the support plate 101. The winding reel is rotatably mounted on the support plate 101 and driven by the ripple motor 1. Multiple transmission wheels 102 are spaced apart along the extension direction of the slide rail 1011. The transmission belt 103 is sleeved on the winding reel and the multiple transmission wheels 102 and connected to the lifting member 104.

[0058] When the ripple motor 1 drives the winding wheel to rotate, the winding wheel drives the lifting component 104 to move via the transmission belt 103. Under the guidance of the slide rail 1011, the lifting component 104 drives the window glass 200 to rise and fall. In this way, the structure of the glass lifting mechanism 100 is simple and the accuracy of driving the window glass 200 to rise and fall is improved.

[0059] Please refer to the following: Figure 10 This application also provides a vehicle 1000, including the window lifting mechanism 100 as described above.

[0060] The vehicle 1000 of this application embodiment improves the accuracy and stability of driving the window glass 200 to rise and fall by setting up a window lifting mechanism 100 including the above-mentioned ripple motor 1, reduces the probability of window accidental pinching and failure to close, and reduces costs.
