[0031] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0032] Reference below Figure 1-Figure 3A pedal mechanism 100 according to an embodiment of the present invention will be described.
[0033] The pedal mechanism 100 according to the first embodiment of the present invention includes a pedal bracket 10, a pedal arm 20, and a damping structure 30. For example, the pedal mechanism 100 may be a brake pedal of a vehicle.
[0034] Reference Figure 1 and Figure 2 The pedal arm 20 is connected to the pedal bracket 10 and is rotatable between an initial position and a maximum rotation position. The pedal arm 20 is rotatably connected to the pedal bracket 10 via a rotation shaft 22.
[0035] For example, the pedal mechanism 100 includes a return mechanism, which can return the pedal arm 20 to its original position when the user lifts his foot and releases the pedal mechanism 100. For example, the pedal mechanism 100 is a brake pedal, and the return mechanism is an electronically controlled brake booster.
[0036] For example, the pedal mechanism 100 includes a limiting mechanism. When the user does not step on the pedal, the limiting mechanism can abut against the piston to limit the initial position of the pedal.
[0037] The damping structure 30 is provided on the pedal bracket 10 and is located on a side adjacent to the initial position in the rotational direction of the pedal arm 20. During the movement of the pedal arm 20 toward the initial position, the pedal arm 20 and the damping structure 30 are adapted to contact in the rotational direction of the pedal arm 20 to form a damping effect on the pedal arm 20. The initial position of the pedal arm 20 refers to the position of the pedal arm 20 after the pedal arm 20 compresses the damping structure 30. The damping effect of the damping structure 30 on the pedal arm 20 is less than the return effect of the return mechanism on the pedal arm 20. By allowing the pedal arm 20 and the damping structure 30 to contact in the rotational direction of the pedal arm 20 during the movement of the pedal arm 20 toward the initial position, the pedal arm 20 can be damped by the damping structure 30 during rebound, thereby reducing the rebound speed of the pedal arm 20, preventing the pedal arm 20 from rotating too quickly, and reducing noise generated by impact. Furthermore, since the pedal is usually in its initial position when an impact sound is generated when the pedal returns, by arranging the damping structure 30 on the pedal bracket 10 on the side adjacent to the initial position in the rotation direction of the pedal arm 20, the damping structure 30 can fully act on the area of the pedal adjacent to the initial position, more effectively reducing the movement speed of the pedal when it is adjacent to the initial position, thereby more effectively reducing the noise generated by the impact.
[0038] For example, the damping structure 30 may include a cylindrical spring 41. When the pedal arm 20 returns, the pedal arm 20 contacts the cylindrical spring 41, and the cylindrical spring 41 is gradually compressed as the pedal arm 20 returns. The cylindrical spring 41 exerts a force on the pedal arm 20 that resists the pedal's rebound direction, thereby reducing the speed of the pedal arm 20's rebound and reducing the noise generated by the impact.
[0039] According to the pedal mechanism 100 of the embodiment of the present invention, by making the pedal arm 20 contact with the damping structure 30 in the rotation direction of the pedal arm 20, the pedal arm 20 can be damped by the damping structure 30 during the process of returning to its original position near the initial position, thereby appropriately reducing the return speed of the pedal arm 20, avoiding the pedal arm 20 rotating too fast to cause a violent collision between the return mechanism and the limiting mechanism, and reducing the noise generated by the collision.
[0040] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The pedal arm 20 is adapted to be in detachable contact with the damping structure 30. The pedal arm 20 has a first stroke and a second stroke. The pedal arm 20 has a damping demarcation position, which is located between an initial position and a maximum rotation position. The initial position and the damping demarcation position form a first stroke, and the second stroke is located on a side of the damping demarcation position away from the initial position.
[0041] When the pedal arm 20 is in the first stroke, the pedal arm 20 and the damping structure 30 are in contact in the direction of rotation of the pedal arm 20. When the pedal arm 20 is in the second stroke, the pedal arm 20 and the damping structure 30 are separated. When the user steps on the pedal, the pedal arm 20 separates from the damping structure 30. When the user releases the pedal, the pedal arm 20 rebounds, first through the second stroke and then through the first stroke.
[0042] By arranging the pedal arm 20 in the first stroke so that the pedal arm 20 and the damping structure 30 contact in the direction of rotation of the pedal arm 20, the pedal arm 20 is damped by the damping structure 30 as it returns to its initial position, effectively reducing the speed at which the pedal returns to its initial position, thereby further reducing noise generated by impact. By arranging the pedal arm 20 in the second stroke so that the pedal arm 20 and the damping structure 30 are separated, the damping structure 30 can be separated from the pedal arm 20 when the user presses the pedal or in the initial stage of the pedal return. At this time, the pedal arm 20 is not damped by the damping structure 30, thereby preventing the pedal arm 20 from returning too slowly and affecting vehicle starting or braking.
[0043] According to some embodiments of the present invention, the ratio of the first stroke to the maximum stroke of the pedal arm 20 is a, and the value of a ranges from 0.1 to 0.25. For example, the value of a can be 0.1, 0.15, 0.2, 0.25, etc. By ensuring that the ratio a of the first stroke to the maximum stroke of the pedal arm 20 is no less than 0.1, the pedal arm 20 can be fully damped by the damping device, allowing the damping device to more effectively reduce the rebound speed of the pedal arm 20. By ensuring that the ratio a of the first stroke to the maximum stroke of the pedal arm 20 is no more than 0.25, the slow return of the pedal arm 20, which may affect the starting or braking of the vehicle, can be avoided.
[0044] According to some embodiments of the present invention, the damping structure 30 is detachably mounted to the pedal bracket 10. This detachable mounting facilitates maintenance or repair of the damping structure 30 and stabilizes the damping structure 30 relative to the vehicle, preventing vibration and displacement of the damping structure 30 with the rotation of the pedal arm 20. For example, the damping structure 30 may include a mounting portion, which may include an external thread structure. The pedal bracket 10 may include an internal thread structure, and the mounting portion and the pedal bracket 10 may be secured together via a threaded connection.
[0045] According to some embodiments of the present invention, referring to Figure 3 The damping structure 30 includes a connecting rod 31 and a damping member 33, a damping chamber 34 is formed in the damping member 33, one end of the connecting rod 31 is connected to the pedal bracket 10, and the other end of the connecting rod 31 extends into the damping chamber 34 and is provided with a damping plate 32, the outer peripheral wall of the damping plate 32 is in contact with the damping member 33, and the damping member 33 is movable relative to the length direction of the connecting rod 31. During the movement of the pedal arm 20 toward the initial position, the pedal arm 20 is suitable for contacting the damping member 33 in the rotation direction of the pedal arm 20 and is suitable for pushing the damping member 33 to move along the length direction of the connecting rod 31 (for example, the e1 direction in the drawing) to form a damping effect on the pedal arm 20. By making the outer peripheral wall of the damping plate 32 contact with the damping member 33 and making the damping member 33 movable in the length direction relative to the connecting rod 31, the friction between the damping member 33 and the connecting rod 31 can be increased when the damping member 33 is moved by the rotation of the pedal arm 20, thereby slowing down the movement speed of the damping member 33 relative to the connecting rod 31. The damping member 33 hinders the movement of the pedal arm 20, thereby slowing down the return speed of the pedal arm 20.
[0046] According to some embodiments of the present invention, referring to Figure 3The damping member 33 includes a damping block 35 and a damping lip 36. A damping cavity 34 is formed in the damping block 35. The damping lip 36 is connected to the inner wall of the damping cavity 34. One end of the damping lip 36 is connected to the inner wall of the damping cavity 34. The other end of the damping lip 36 is a free end and extends in a direction away from the pedal arm 20 (for example, the direction e1 in the accompanying drawings). When the pedal arm 20 moves toward the initial position, the outer peripheral wall of the damping plate 32 contacts the damping lip 36 to form a damping effect on the pedal arm 20. By making the other end of the damping lip 36 a free end and extending in a direction away from the pedal arm 20, when the pedal arm 20 rebounds and the pedal arm 20 moves in a direction close to the connecting rod 31, the movement direction of the connecting rod 31 relative to the damping member 33 (for example, the direction e3 in the accompanying drawings) is opposite to the extension direction of the free end of the damping lip 36 (for example, the direction e1 in the accompanying drawings), and the friction force of the damping lip 36 on the connecting rod 31 is greater, which more significantly slows down the movement speed of the damping member 33 relative to the connecting rod 31, thereby slowing down the movement speed of the pedal arm 20; when the pedal arm 20 is stepped on and the pedal arm 20 moves in a direction away from the connecting rod 31, the movement direction of the connecting rod 31 relative to the damping member 33 is the same as the extension direction of the free end of the damping lip 36, the friction force of the damping lip 36 on the connecting rod 31 is small, and the movement speed of the damping member 33 relative to the connecting rod 31 changes less, which can reduce the impact of the damping structure 30 on the user's pedaling process.
[0047] According to some embodiments of the present invention, referring to Figure 3The damping chamber 34 includes a first chamber 37 and a second chamber 38 arranged along the length direction of the connecting rod 31. The first chamber 37 is located on the side of the second chamber 38 close to the pedal arm 20. A step wall 39 is formed between the inner peripheral wall of the first chamber 37 and the inner peripheral wall of the second chamber 38. One end of the damping lip 36 is connected to the step wall 39 and the damping lip 36 is spaced apart from the inner peripheral wall of the second chamber 38. In the direction from one end of the damping lip 36 to the other end of the damping lip 36 (for example, the e1 direction in the accompanying drawings), the damping lip 36 extends obliquely toward the central axis of the connecting rod 31 and the inner peripheral wall of the second chamber 38 extends obliquely toward the central axis of the connecting rod 31. By forming a step wall 39 between the inner circumferential wall of the first cavity 37 and the inner circumferential wall of the second cavity 38, and by connecting one end of the damping lip 36 to the step wall 39 and separating the damping lip 36 from the inner circumferential wall of the second cavity 38, after the damping lip 36 is squeezed and deformed by the connecting rod 31, there is a space in the second cavity 38 that can accommodate the damping lip 36, thereby preventing the damping lip 36 from applying excessive pressure to the connecting rod 31 in a direction perpendicular to the axial direction of the connecting rod 31 (for example, the direction e2 in the accompanying drawings) and causing it to become stuck. By extending the damping lip 36 in an inclined direction toward the central axis of the connecting rod 31 and extending the inner circumferential wall of the second cavity 38 in an inclined direction away from the central axis of the connecting rod 31, after the damping lip 36 is squeezed and deformed by the connecting rod 31, the inner circumferential wall of the second cavity 38 can limit the damping lip 36, thereby preventing the damping lip 36 from being damaged due to excessive deformation.
[0048] According to some embodiments of the present invention, referring to Figure 1-Figure 3The pedal arm 20 is suitable for detachably contacting the damping member 33, the pedal arm 20 has a first stroke and a second stroke, the pedal arm 20 has a damping demarcation position, the first stroke is formed between the initial position and the damping demarcation position, and the second stroke is located on the side of the damping demarcation position away from the initial position; wherein, when the pedal arm 20 is in the first stroke, the pedal arm 20 contacts the damping member 33 in the rotation direction of the pedal arm 20, and when the pedal arm 20 is in the second stroke, the pedal arm 20 is separated from the damping member 33; when the pedal arm 20 is in the first stroke and in the process of the pedal arm 20 moving toward the initial position, the outer peripheral wall of the damping plate 32 contacts the damping lip 36 to form a damping effect on the pedal arm 20. By ensuring that the outer peripheral wall of the damping plate 32 contacts the damping lip 36 when the pedal arm 20 is in the first stroke and moving toward the initial position, the pedal arm 20 is subjected to a greater frictional force from the damping lip 36 when moving toward the initial position in the first stroke, more effectively reducing the speed of the pedal near the initial position, thereby more effectively reducing the noise generated by impact. By ensuring that the pedal arm 20 is in the second stroke and the pedal arm 20 is separated from the damping structure 30, the damping structure 30 can be separated from the pedal arm 20 during the initial stage of the pedal being depressed by the user or the pedal returning to its original position. During this period, the pedal arm 20 is not damped by the damping structure 30, thereby preventing the pedal arm 20 from returning too slowly and affecting the starting or braking of the vehicle.
[0049] According to some embodiments of the present invention, referring to Figure 1-Figure 3 The pedal arm 20 is adapted to be in detachable contact with the damping member 33. The pedal arm 20 has a first stroke and a second stroke. The pedal arm 20 has a damping demarcation position. The first stroke is formed between the initial position and the damping demarcation position. The second stroke is located on a side of the damping demarcation position away from the initial position. When the pedal arm 20 is in the first stroke, the pedal arm 20 is in contact with the damping member 33 in the rotation direction of the pedal arm 20. When the pedal arm 20 is in the second stroke, the pedal arm 20 is separated from the damping member 33.
[0050] The damping member 33 is movable between a first position and a second position relative to the length direction of the connecting rod 31. When the pedal arm 20 is at the initial position, the damping member 33 is at the first position. When the pedal arm 20 is at the damping boundary position, the damping member 33 is at the second position.
[0051] The damping structure 30 also includes a spring 41, which is extendable and deformable along the length of the connecting rod 31. One end of the spring 41 is connected to the other end of the connecting rod 31, and the other end of the spring 41 is connected to the damping member 33. As the pedal arm 20 moves from the initial position toward the damping threshold position, the spring 41 is configured to drive the damping member 33 to a second position. By including the spring 41 in the damping structure 30 and enabling the spring 41 to drive the damping member 33 to the second position as the pedal arm 20 moves from the initial position toward the damping threshold position, the damping structure 30 is positioned in the second position after the pedal arm 20 is depressed, ensuring that the damping structure 30 provides sufficient damping and cushioning for the pedal arm 20 during its rebound.
[0052] According to some embodiments of the present invention, the damping member 33 is a rubber member. By making the damping member 33 a rubber member, the noise generated when the damping member 33 collides with the pedal arm 20 can be reduced.
[0053] For example, the damping member 33 is a rubber member, and a limiting protrusion 42 is provided on the inner wall of the damping chamber 34 of the damping member 33. The limiting protrusion 42 is a rubber member. When the damping member 33 is in the first position, the limiting protrusion 42 abuts against the damping plate 32 in the axial direction of the connecting rod 31, thereby fixing the position of the damping member 33 relative to the connecting rod 31. By making the limiting protrusion 42 a rubber member, the noise caused by the collision between the limiting protrusion 42 and the damping plate 32 can be reduced, and the limiting protrusion 42 can provide a certain buffering effect on the damping plate 32.
[0054] According to some embodiments of the present invention, referring to Figure 3 One end of the connecting rod 31 is threadedly connected to the pedal bracket 10. By threading one end of the connecting rod 31 to the pedal bracket 10, the connecting rod 31 can be fixed relative to the pedal bracket 10 to prevent the damping structure 30 from falling off and causing the damping structure 30 to lose its function.
[0055] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The pedal arm 20 includes a connecting end 25 and a pedaling end 26. The connecting end 25 is rotatably connected to the pedal bracket 10, and the damping structure 30 is closer to the connecting end 25 than to the pedaling end 26. When the pedal arm 20 rotates, the portion of the pedal arm 20 closer to the connecting end rotates a shorter distance. By positioning the damping structure 30 closer to the connecting end 25 than to the pedaling end 26, the damping structure 30 can effectively damp the shorter distance, facilitating miniaturization of the damping structure 30. This also prevents the damping structure 30 from being accidentally damaged or detached when the user uses the pedaling end 26.
[0056] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The pedal arm 20 includes a pedal arm body 27 and a pedal stopper 28. The pedal stopper 28 is disposed on the pedal arm body 27 and protrudes toward the damping structure 30. The pedal arm 20 is adapted to contact the damping structure 30 via the pedal stopper 28. The inclusion of the pedal stopper 28 in the pedal arm 20 increases the contact area between the damping structure 30 and the pedal arm 20, thereby making the contact between the damping structure 30 and the pedal arm 20 more stable. The protrusion of the pedal stopper 28 toward the damping structure 30 facilitates contact between the pedal stopper 28 and the damping structure 30.
[0057] The vehicle according to the second embodiment of the present invention includes: a vehicle body and the pedal mechanism 100 according to the first embodiment of the present invention, wherein the pedal bracket 10 is mounted on the vehicle body.
[0058] According to the vehicle of the embodiment of the present invention, by including the pedal mechanism 100 according to the embodiment of the first aspect of the present invention, the pedal mechanism 100 includes a damping structure 30, which can appropriately reduce the return speed of the pedal arm 20, avoid a violent collision between the piston of the return mechanism and the limiting mechanism, and reduce the noise generated by the collision.
