Description

Technical Field

[0002] With the rapid development of vehicle electrification, the electrification transformation of chassis components has taken a big step forward. As we are familiar with, there are existing technologies such as by-wire shifting or steer-by-wire (SBW), integrated electric braking (IEB), etc.

[0003] In the field of braking, the electro-mechanical braking (EMB) technology is now vigorously developed by major original equipment manufacturers (OEMs). Some OEMs even plan to push it into mass production in the near future. Under the application of EMB, the brake pedal only provides the braking feeling to the driver and sends a Controller Area Network (CAN) signal to the brake controller, and the brake controller finally actuates the EMB to perform braking. This means that the brake pedal will be separated from the braking force transmission system. Therefore, an E pedal for braking is needed.

[0056] The gear device 20 can be connected to the pedal device 10 and can be provided with an internal gear 21, at least one planetary gear 22, and a sun gear assembly 23. The internal gear 21 can mesh with the planetary gear 22, and the planetary gear 22 can mesh with the sun gear assembly 23.

[0057] The internal gear 21 can have an outer peripheral wall 24. The brake pedal arm 15 can connect the brake pedal body 13 and the internal gear 21, and the accelerator pedal arm can connect the accelerator pedal body and the internal gear 21. Specifically, the brake pedal arm 15 of the brake pedal assembly 11 and the accelerator pedal arm of the accelerator pedal assembly 12 can be connected to the outer peripheral wall 24 of the internal gear 21. In an exemplary embodiment of the present utility model, the brake pedal arm 15 of the brake pedal assembly 11 and the accelerator pedal arm of the accelerator pedal assembly 12 can be integrally formed and can have a common end, and the common end is connected to the outer peripheral wall 24 of the internal gear 21.

[0058] The internal gear 21 can be further provided with a first rotating shaft 25, and the internal gear 21 can be rotatably connected to the bracket 90 through the first rotating shaft 25.

[0059] Therefore, when the driver steps on the brake pedal cover 14 or the accelerator pedal body, the internal gear 21 can rotate relative to the bracket 90 in the first rotation direction ( Figure 8 the direction indicated by the arrow in).

[0060] In addition, the planetary gear 22 can mesh with the internal gear 21 and can be provided with a second rotating shaft 26. The planetary gear 22 can be rotatably connected to the bracket 90 through the second rotating shaft 26.

[0061] Therefore, when the internal gear 21 rotates relative to the bracket 90, the planetary gear 22 can rotate relative to the bracket 90 in the first rotation direction.

[0062] The sun gear assembly 23 can mesh with the planetary gears 22 and can be provided with a sun gear 27, a third rotating shaft 28, a first rotating member 34, and a second rotating member 35.

Figure 13 FIG. [ID] is a perspective view showing a first state of a rod assembly 40 of an integrated pedal device according to an exemplary embodiment of the present invention. Figure 14 FIG. [ID] is a perspective view showing a second state of a rod assembly 40 of an integrated pedal device according to an exemplary embodiment of the present invention. Figure 15 FIG. [ID] is a perspective view showing the rod assembly 40 of the integrated pedal device accommodated in the rod assembly accommodating device 30 according to an exemplary embodiment of the present invention.

[0065] The rod assembly accommodating device 30 can be provided as a hollow tube and can be provided with a first hanging nose 31. In an exemplary embodiment of the present invention, the first hanging nose 31 can extend vertically upward in the radial direction from the outer peripheral wall of the rod assembly accommodating device 30.

[0066] The rod assembly 40 can be disposed in the rod assembly accommodating device 30. The rod assembly 40 can include a first rod 41 and a second rod 42. Specifically, the first rod 41 and the second rod 42 can be formed to be able to approach or move away from each other in opposite directions in the axial direction. In an exemplary embodiment of the present invention, the first rod 41 and the second rod 42 can be formed as hollow tubes.

[0067] A first protrusion 43 can be provided at a first end of the first rod 41. The first protrusion 43 can extend outward in the axial direction from the end of the first rod 41. A second protrusion 44 can be provided at a second end of the second rod 42. The second protrusion 44 can extend outward in the axial direction from the end of the second rod 42.

[0068] The outer peripheral wall of the rod assembly accommodating device 30 may be provided with a first opening 32, and the first rod 41 may be further provided with a third protrusion 45. The third protrusion 45 may extend radially outward from the outer peripheral wall of the first rod 41 and may protrude through the first opening 32. In an exemplary embodiment of the present invention, the first opening 32 may be formed to have a predetermined length so that the first rod 41 can move in the axial direction.

[0069] Figure 16 FIG. is a perspective view showing a first state in which a trigger cable 50 of an integrated pedal device according to an exemplary embodiment of the present invention is connected to a second nose 46. Figure 17 FIG. is a perspective view showing a second state in which a trigger cable 50 of an integrated pedal device according to an exemplary embodiment of the present invention is connected to a second nose 46.

[0070] The connecting assembly 17 may be further provided with an L-shaped rod 19. Specifically, one end of the L-shaped rod 19 may be pivotally connected to the brake pedal body 13, and the other end of the L-shaped rod 19 may be connected to the first end of the trigger cable 50 (see Figure 4 and Figure 5 ). When the driver steps on the brake pedal cover 14, the V-shaped elastic member 16 may be compressed so that the other end of the protruding rod 18 can pass through the through hole of the brake pedal body 13, so that the other end of the L-shaped rod 19 can move in a first moving direction ( Figure 5 as indicated by the arrow in).

[0071] The first end of the trigger cable 50 may be connected to the other end of the L-shaped rod 19 so that when the other end of the L-shaped rod 19 moves in the first moving direction, the trigger cable 50 can be pulled. In an exemplary embodiment of the present invention, the trigger cable 50 may be connected to the L-shaped rod 19 through an elastic member to provide a more comfortable pedal feel for the driver.

[0072] The second rod 42 may be provided with a second nose 46. In an exemplary embodiment of the present invention, the second nose 46 may extend vertically upward in the radial direction from the outer peripheral wall of the second rod 42.

[0073] The outer peripheral wall of the rod assembly accommodating device 30 may be provided with a second opening 33, and the second nose 46 may protrude through the second opening 33 so that the second end of the trigger cable 50 can be connected to the second nose 46, so that when the driver steps on the brake pedal, the trigger cable 50 can cause the second nose 46 to rotate in a first rotation direction ( Figure 13 the direction indicated by the arrow in).

[0074] In an exemplary embodiment of the present utility model, the second opening 33 may be formed such that the second rod 42 can rotate within a range of at least 180 degrees and may be formed with a predetermined length such that the second rod 42 can move in the axial direction.

[0075] In addition, the first rod 41 may be provided with a third spring 47 (see Figure 14 ), and the third spring 47 may be disposed between the rod assembly accommodating device 30 and the first rod 41 to provide a return force for the first rod 41; the second rod 42 may be provided with a fourth spring 48 (see Figure 14 ), and the fourth spring 48 may be disposed between the rod assembly accommodating device 30 and the second rod 42 to provide a return force for the second rod 42.

[0076] The third rotating shaft 28 may be provided with a limiting rod 38, and the limiting rod 38 may contact the third protrusion 45 and may limit the rotation of the sun gear assembly 23.

[0077] Specifically, when the driver steps on the brake pedal cover 14 and the brake pedal body 13, the third protrusion 45 on the first rod 41 may move in the first direction ( Figure 16 the direction indicated by the arrow in ), so that the third protrusion 45 does not limit the rotation of the limiting rod 38 of the third rotating shaft 28 of the sun gear assembly 23. Therefore, when the driver steps on the brake pedal cover 14, the stroke can be larger.

[0078] On the other hand, when the driver steps on the accelerator pedal body, the third protrusion 45 may limit the rotation of the limiting rod 38 of the third rotating shaft 28 of the sun gear assembly 23. Therefore, when the driver steps on the accelerator pedal body, the stroke can be smaller.

[0079] To facilitate distinguishing whether the driver steps on the accelerator pedal or the brake pedal, a brake light switch may be provided on the side of the first opening 32 of the rod assembly accommodating device 30 away from the center. When the driver steps on the brake pedal cover 14, the third protrusion 45 may move in the first direction, thereby triggering the brake light switch, from which it can be known that the brake pedal is stepped on. On the other hand, when the driver steps on the accelerator pedal body, the third protrusion 45 does not move in the first direction, thereby not triggering the brake light switch, from which it can be known that the accelerator pedal is stepped on. However, the present utility model is not limited to the above embodiments.

[0080] Figure 18 is a perspective view showing the first spring 60 of the integrated pedal device according to an exemplary embodiment of the present utility model is disposed on the pedal device 10, Figure 19It is a perspective view showing the first state of the second spring 61 of the integrated pedal device according to an exemplary embodiment of the present utility model, Figure 20 It is a perspective view showing the second state of the second spring 61 of the integrated pedal device according to an exemplary embodiment of the present utility model.

[0081] The first spring 60 can be disposed between the pedal device 10 and the vehicle body to provide a return force for the pedal.

[0082] The first end of the second spring 61 can be connected to the first hanging nose 31. Specifically, the friction member 70 can be disposed on the outer peripheral wall 24 of the internal gear 21, and a through hole 71 (see Figure 9 ) can be provided, and the first end of the second spring 61 can be connected to the first hanging nose 31 through the through hole 71.

[0083] The roller device 80 can be supported on the bracket 90 and can be in contact with the friction member 70. Specifically, the roller device 80 can be provided with a first roller 81, a second roller 82 and a roller shaft 83. The outer surfaces of the first roller 81 and the second roller 82 can be in contact with the friction member 70, and the roller shaft 83 can be connected to the second end of the second spring 61.

[0084] In addition, the roller device 80 is provided with a one-way stopper 84, such that in the case where the pedal device is stepped on, the roller device 80 can remain stationary, and in the case where the pedal device is released, the roller device 80 can rotate in the first rotation direction.

[0085] Figure 21 It is a perspective view showing the bracket 90 of the integrated pedal device according to an exemplary embodiment of the present utility model, Figure 22 It is a perspective view showing the gear device 20 and the roller device 80 of the integrated pedal device installed on the bracket 90 according to an exemplary embodiment of the present utility model, Figure 23 It is a front view showing the gear device 20 and the roller device 80 of the integrated pedal device installed on the bracket 90 according to an exemplary embodiment of the present utility model.

[0086] The bracket 90 can be disposed on the vehicle body and can be used to support the gear device 20 and the roller device 80. Specifically, the bracket 90 can be provided with a first chute 91 extending in the vertical direction. The rod assembly accommodating device 30 can be disposed in the first chute 91 and can move in the vertical direction along the first chute 91.

[0087] Further, the first rotating member 34 may be provided with a second sliding groove 36 corresponding to the first protrusion 43, and the second rotating member 35 may be provided with a third sliding groove 37 corresponding to the second protrusion 44. When the first rod 41 and the second rod 42 move away from each other in opposite directions, the first protrusion 43 may be inserted into the second sliding groove 36 of the first rotating member 34, and the second protrusion 44 may be inserted into the third sliding groove 37 of the second rotating member 35. In addition, the first protrusion 43 may move along the second sliding groove 36, and the second protrusion 44 may move along the third sliding groove 37.

[0088] The second sliding groove 36 and the third sliding groove 37 may have the same shape. In an exemplary embodiment of the present invention, the second sliding groove 36 and the third sliding groove 37 may be formed eccentrically with respect to the centers of the first rotating member 34 and the second rotating member 35, respectively. Specifically, as the first protrusion 43 and the second protrusion 44 move in the second sliding groove 36 and the third sliding groove 37, the distances between the first protrusion 43 and the second protrusion 44 and the third rotating shaft 28 may decrease.

[0089] Figure 24 FIG. is a side view showing different states of the second spring 61 and the sun gear assembly 23 of the integrated pedal device according to an exemplary embodiment of the present invention.

[0090] The cases where the driver steps on the acceleration pedal main body and the brake pedal cover 14 are described below, respectively.

[0091] When the driver steps on the acceleration pedal main body, the internal gear 21 may rotate in a first rotation direction relative to the bracket 90, the planetary gear 22 may rotate about its own axis in the first rotation direction relative to the bracket 90, and the sun gear 27, the first rotating member 34, and the second rotating member 35 may rotate in a second rotation direction ( Figure 24 the direction indicated by the arrow in FIG.) relative to the bracket 90. Since the roller device 80 is provided with a one-way stopper 84, the first roller 81 and the second roller 82 of the roller device 80 do not rotate, and the outer surfaces of the first roller 81 and the second roller 82 of the roller device 80 may rub against the friction member 70.

[0092] When the driver steps on the brake pedal cover 14, the trigger cable 50 may move in a first moving direction, so that the second rod 42 may rotate in a first rotation direction relative to the first rod 41, and at the same time, the first rod 41 may move away from the second rod 42, so that the first rod 41 and the second rod 42 may move away from each other in opposite directions, so that the first protrusion 43 may be inserted into the second sliding groove 36, and the second protrusion 44 may be inserted into the third sliding groove 37.

[0093] When the driver continues to step on the brake pedal cover 14 and further steps on the brake pedal body 13, the internal gear 21 can rotate relative to the bracket 90 in the first rotation direction, the planetary gear 22 can rotate relative to the bracket 90 in the first rotation direction around its own axis, and the sun gear 27, the first rotating member 34, and the second rotating member 35 can rotate relative to the bracket 90 in the direction opposite to the first rotation direction. Since the roller device 80 is provided with a one-way stopper 84, the first roller 81 and the second roller 82 of the roller device 80 do not rotate, and the outer surfaces of the first roller 81 and the second roller 82 of the roller device 80 can rub against the friction member 70. Since the second chute 36 and the third chute 37 are eccentric with respect to the centers of the first rotating member 34 and the second rotating member 35, the rod assembly accommodating device 30 where the first rod 41 and the second rod 42 are located can move along the second chute 36 and the third chute 37 while being able to move downward along the first chute 91. Since the first hanging nose 31 of the rod assembly accommodating device 30 is connected to the second spring 61, the second spring 61 can be stretched downward so that the frictional force between the first roller 81, the second roller 82 of the roller device 80 and the friction member 70 increases, thereby making the pedal feel stiffer.

[0094] The situations where the driver releases the accelerator pedal body and the brake pedal cover 14 are described separately below.

[0095] When the driver releases the accelerator pedal body, the first spring 60 can provide a returning force for the accelerator pedal body, so that the internal gear 21 can rotate relative to the bracket 90 in the direction opposite to the first rotation direction, the planetary gear 22 can rotate relative to the bracket 90 in the direction opposite to the first rotation direction around its own axis, and the sun gear 27, the first rotating member 34, and the second rotating member 35 can rotate relative to the bracket 90 in the first rotation direction. Since the roller device 80 is provided with a one-way stopper 84, the first roller 81 and the second roller 82 of the roller device 80 can rotate in the first rotation direction, so that there is almost no friction between the first roller 81, the second roller 82 of the roller device 80 and the friction member 70.

[0096] When the driver releases the brake pedal body 13, the first spring 60 can provide a return force for the brake pedal body 13, such that the internal gear 21 can rotate relative to the bracket 90 in a direction opposite to the first rotation direction, the planetary gear 22 can rotate relative to the bracket 90 in a direction opposite to the first rotation direction, and the sun gear 27, the first rotating member 34, and the second rotating member 35 can rotate relative to the bracket 90 in the first rotation direction. The second spring 61 can be elastically reset. Since the second chute 36 and the third chute 37 are eccentric with respect to the centers of the first rotating member 34 and the second rotating member 35, the rod assembly accommodating device 30 where the first rod 41 and the second rod 42 are located can move along the second chute 36 and the third chute 37 while being able to move upward along the first chute 91. Since the roller device 80 is provided with a one-way stopper 84, the first roller 81 and the second roller 82 of the roller device 80 can rotate in the first rotation direction, thereby reducing the frictional force between the first roller 81, the second roller 82 of the roller device 80 and the friction member 70. As the second spring 61 is fully reset, there is almost no friction between the first roller 81, the second roller 82 of the roller device 80 and the friction member 70.

[0097] When the driver continues to release the brake pedal body 13 and further releases the brake pedal cover 14, the trigger cable 50 can move in a direction opposite to the first moving direction, such that the second rod 42 can rotate relative to the first rod 41 in the second rotation direction. The third spring 47 can provide a return force for the first rod 41, such that the first rod 41 can move closer to the second rod 42. At the same time, the fourth spring 48 can provide a return force for the second rod 42, such that the first rod 41 and the second rod 42 can move closer to each other, so that the first protrusion 43 and the second protrusion 44 can be accommodated in the rod assembly accommodating device 30.

[0098] Figure 25 It is a schematic diagram showing the pedal stroke and pedal force of an integrated pedal device according to an exemplary embodiment of the present invention.

[0099] The application / release curve of the accelerator pedal of the integrated pedal device according to an exemplary embodiment of the present invention has a fixed force drop, so that the driver can achieve a comfortable long-distance driving.

[0100] The reaction force of the brake pedal of the integrated pedal device according to an exemplary embodiment of the present invention increases exponentially with the stroke, and the shapes of the second chute 36 of the first rotating member 34 and the third chute 37 of the second rotating member 35 can achieve different pedal reaction force curves.

[0101] The full strokes of the accelerator pedal and the brake pedal of the integrated pedal device according to the exemplary embodiments of the present invention are different. For example, the full stroke of the accelerator pedal in the integrated pedal device of the present exemplary embodiment is approximately 50 mm, while the full stroke of the brake pedal is approximately 70 mm.

[0102] The reaction force of the brake pedal of the integrated pedal device according to the exemplary embodiments of the present invention can be as high as 40 kgf, while the maximum reaction force of the accelerator pedal can only reach about 3 kgf.

[0103] In summary, the pedal feelings are different when braking and accelerating with the integrated pedal device according to the exemplary embodiments of the present invention.

[0104] Moreover, the integrated pedal device of the present invention can save components through the integrated accelerator pedal assembly and brake pedal assembly, thereby achieving cost savings.

[0105] In addition, the layout design of the integrated pedal device of the present invention is simple and can save the interior space of the vehicle.
