Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a motorcycle. Background Technology

[0002] Currently, due to manufacturing errors, the center of the caliper and the center of the brake disc are not completely aligned after the motorcycle is assembled. This causes the friction pads on both sides of the caliper to have difficulty contacting the brake disc simultaneously during braking, resulting in a significant difference in the wear of the left and right friction pads. The friction pad that contacts the brake disc first experiences relatively greater wear, while the friction pad that contacts the brake disc later experiences relatively less wear. This affects the inconsistent service life of the two friction pads, leading to a reduction in the service life of the caliper.

[0003] To solve the above problems and improve the service life of calipers, there are two traditional solutions: First, adopt a structure of left and right floating brake discs + opposed calipers. That is, the position of the calipers is fixed, and the brake disc is designed to float left and right, so that the brake disc can slide left and right to absorb axial errors. However, this method has shortcomings. For example, the brake disc needs to be divided into inner and outer rings and connected by riveting. If the diameter of the brake disc itself is too small, there is not enough space to arrange the inner ring, so the floating design of the brake disc cannot be realized.

[0004] Secondly, a structure of left and right floating calipers + non-floating brake discs is adopted. That is, the position of the brake disc is fixed and the caliper is mounted on the sliding pin, so that the caliper can slide left and right to absorb axial error. However, this method also has shortcomings. For example, because of the presence of the sliding pin, the space occupied by the caliper is increased, especially in the radial dimension of the wheel axle.

[0005] Therefore, for situations where the brake disc diameter is too small and the radial space of the wheel axle is small, neither the left and right floating brake disc + non-floating caliper structure nor the left and right floating caliper + non-floating brake disc structure can be used. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this application provides a motorcycle that can adapt to a brake disc with a small diameter and limited radial space on the wheel axle.

[0007] One embodiment of this application provides a motorcycle, including a frame, a rocker arm, an axle, a running gear assembly, a drive assembly, and a braking assembly. The rocker arm is at least partially disposed on the frame. The axle is at least partially disposed on the rocker arm. The running gear assembly is at least partially disposed on the axle. The drive assembly is used to drive the running gear assembly. The braking assembly is used to brake the running gear assembly. The braking assembly includes a brake disc, a caliper, and a connector. The axial direction of the brake disc is parallel to the axial direction of the axle. The brake disc is connected to the running gear assembly and rotates with the operation of the running gear assembly. The caliper is connected to the axle via the connector to cooperate with the brake disc to achieve braking. The connector is slidable relative to the axial direction of the axle to drive the caliper to slide relative to the axial direction of the axle.

[0008] In the motorcycle provided in this application, the caliper is mounted on a connecting member, which is sleeved on the wheel axle and can slide along the axial direction of the wheel axle. This allows the two friction pads to move axially along the brake disc, thereby enabling the two friction pads to float relative to the brake disc. This allows the two friction pads to more synchronously conform to the opposite sides of the brake disc, and also makes the friction between the two friction pads and the brake disc more even, so that the wear of the brake disc is more evenly distributed between the two friction pads. This results in the two friction pads reaching their service life more closely and simultaneously, thus improving the overall service life of the caliper. Furthermore, in the motorcycle provided in this application, because the caliper is fixedly mounted on the connecting member, the structure requiring a floating caliper is avoided, eliminating the need for a sliding pin. This allows the motorcycle to adapt to situations where the radial space of the wheel axle is small. Moreover, because the two friction pads can float, the brake disc does not need to float, and the position of the brake disc can be fixed, thus avoiding the structure of a brake disc floating laterally. This allows the motorcycle to adapt to situations where the brake disc diameter is too small. Therefore, the motorcycle provided in this application can achieve more synchronized contact between the two friction pads and the brake disc when the brake disc diameter is too small and the radial space of the wheel axle is small, so that the friction between the two friction pads and the brake disc is closer to the same, thereby improving the service life of the caliper.

[0009] In some embodiments, the braking assembly includes two limiting surfaces that are arranged facing each other and located on opposite sides of the connecting member along the axial direction of the wheel axle. The two limiting surfaces are used to limit the sliding distance of the connecting member, thereby limiting the movement distance of the two friction pads.

[0010] In some embodiments, one end of the axle is connected to the rocker arm, and the side of the rocker arm facing the other end of the axle forms a limiting surface.

[0011] In some embodiments, the braking assembly further includes a limiting bushing, which is sleeved on the outer periphery of the wheel axle, and the side of the limiting bushing facing the rocker arm forms a limiting surface.

[0012] In some embodiments, the braking assembly further includes a sliding bushing, which is sleeved on the outer periphery of the wheel axle and located between the limiting bushing and the rocker arm. A connecting member is sleeved on the outer periphery of the sliding bushing and is slidable along the sliding bushing.

[0013] In some embodiments, the braking assembly further includes a fixing member connected to the rocker arm, the fixing member being sleeved on the outer periphery of the wheel axle, and a connecting member being sleeved on the outer periphery of the fixing member, the connecting member being slidable along the fixing member.

[0014] In some embodiments, the fastener includes an inner section and an outer section, which are arranged along the axial direction of the wheel axle. The connector is sleeved on the outer periphery of the inner section, and the end face of the outer section facing the inner section forms a limiting surface.

[0015] In some embodiments, the outer peripheral wall of the inner section is provided with a groove, and the braking assembly further includes a stop member, which is disposed in the groove and at least partially protrudes from the groove, and the side of the stop member facing the connector forms a limiting surface.

[0016] In some embodiments, the braking assembly further includes two flexible members, and the connecting member is provided with a mounting groove on opposite sides along the axial direction of the wheel axle. The mounting groove is arranged around the axis of the wheel axle, and each mounting groove is used to receive a flexible member. The flexible member protrudes at least partially from the mounting groove to contact the limiting surface.

[0017] In some embodiments, the braking assembly further includes two ring plates, which are located on opposite sides of the connecting member along the axial direction of the wheel axle, with one ring plate between each flexible member and the limiting surface on the corresponding side.

[0022] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0023] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Currently, due to manufacturing errors, the center of the caliper and the center of the brake disc are not completely aligned after the motorcycle is assembled. This causes the friction pads on both sides of the caliper to have difficulty contacting the brake disc simultaneously during braking, resulting in a significant difference in the wear of the left and right friction pads. The friction pad that contacts the brake disc first experiences relatively greater wear, while the friction pad that contacts the brake disc later experiences relatively less wear. This affects the inconsistent service life of the two friction pads, leading to a reduction in the service life of the caliper.

[0026] To address these issues and improve caliper lifespan, two traditional solutions exist: First, a floating brake disc with opposing calipers is used. The calipers are fixed, while the brake discs are designed to float left and right, absorbing axial errors. However, this method has drawbacks. For example, the brake disc needs to be divided into inner and outer rings, connected by riveting. If the brake disc diameter is too small, there isn't enough space for the inner ring, making the floating design impossible. Second, a floating caliper with a non-floating brake disc is used. The brake disc is fixed, and the calipers are mounted on sliding pins, allowing them to slide left and right to absorb axial errors. This method also has drawbacks. For instance, the sliding pins increase the space occupied by the calipers, especially in the radial dimension of the wheel axle. Therefore, for situations where the brake disc diameter is too small and there is limited space in the radial dimension of the wheel axle, neither a floating brake disc with a non-floating caliper nor a floating caliper with a non-floating brake disc structure is suitable.

[0027] To address the shortcomings of existing technologies, this application provides a motorcycle designed to achieve more synchronized contact between the two friction pads and the brake disc, especially when the brake disc diameter is too small and the radial space of the wheel axle is limited. This results in more uniform friction between the two friction pads and the brake disc, thereby improving the service life of the caliper. The motorcycle includes a frame, a rocker arm, a wheel axle, a running gear assembly, a drive assembly, and a braking assembly. The rocker arm is at least partially mounted on the frame. The wheel axle is at least partially mounted on the rocker arm. The running gear assembly is at least partially mounted on the wheel axle. The drive assembly drives the running gear assembly. The braking assembly brakes the running gear assembly. The braking assembly includes a brake disc, a caliper, and a connector. The axial direction of the brake disc is parallel to the axial direction of the wheel axle. The brake disc is connected to the running gear assembly and rotates with the running gear assembly. The caliper is connected to the wheel axle via the connector to cooperate with the brake disc for braking. The connector can slide relative to the axial direction of the wheel axle, thereby causing the caliper to slide relative to the axial direction of the wheel axle.

[0028] In the motorcycle provided in this application, the caliper is mounted on a connecting member, which is sleeved on the wheel axle and can slide along the axial direction of the wheel axle. This allows the two friction pads to move axially along the brake disc, thereby enabling the two friction pads to float relative to the brake disc. This allows the two friction pads to more synchronously conform to the opposite sides of the brake disc, and also makes the friction between the two friction pads and the brake disc more even, so that the wear of the brake disc is more evenly distributed between the two friction pads. This results in the two friction pads reaching their service life more closely and simultaneously, thus improving the overall service life of the caliper. Furthermore, in the motorcycle provided in this application, because the caliper is fixedly mounted on the connecting member, the structure requiring a floating caliper is avoided, eliminating the need for a sliding pin. This allows the motorcycle to adapt to situations where the radial space of the wheel axle is small. Moreover, because the two friction pads can float, the brake disc does not need to float, and the position of the brake disc can be fixed, thus avoiding the structure of a brake disc floating laterally. This allows the motorcycle to adapt to situations where the brake disc diameter is too small. Therefore, the motorcycle provided in this application can achieve more synchronized contact between the two friction pads and the brake disc when the brake disc diameter is too small and the radial space of the wheel axle is small, so that the friction between the two friction pads and the brake disc is closer to the same, thereby improving the service life of the caliper.

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figure 1 and Figure 2This application provides a motorcycle 100, including a frame 11, a rocker arm 12, an axle 13, a running gear 14, a drive assembly 15, and a braking assembly 16. The frame 11 forms the overall structure of the motorcycle 100. One end of the rocker arm 12 is connected to the frame 11, and the other end extends away from the frame 11. The axle 13 is connected to the end of the rocker arm 12 away from the frame 11. The running gear 14 is disposed on the axle 13. The drive assembly 15 is disposed on the frame 11 and connected to the running gear 14. The drive assembly 15 drives the running gear 14 to move, causing the running gear 14 to move the frame 11, thereby propelling the motorcycle 100. The braking assembly 16 is disposed on the rocker arm 12 and connected to the running gear 14. The braking assembly 16 brakes the running gear 14, thereby slowing down, braking, or keeping the motorcycle 100 at a stop.

[0031] Please see Figure 2 In some embodiments, the braking assembly 16 includes a brake disc 161 and a caliper 162. The brake disc 161 is connected to the travel assembly 14 and rotates with the operation of the travel assembly 14. The caliper 162 includes two opposing friction pads 1621, with the brake disc 161 at least partially located between the two friction pads 1621. The two friction pads 1621 are designed to approach each other until they rub against opposite sides of the brake disc 161 to prevent rotation of the brake disc 161, thereby braking the operation of the travel assembly 14.

[0032] In some embodiments, the axial direction of the brake disc 161 is parallel to the axial direction of the axle 13. The brake assembly 16 also includes a connector 163. The caliper 162 is fixedly connected to the connector 163, the connector 163 is sleeved on the axle 13, and the connector 163 is slidable along the axial direction of the axle 13. The connector 163 extends along an axis perpendicular to the wheel axle 13. The caliper 162 is located at the end of the connector 163 away from the wheel axle 13. The two friction pads 1621 extend in a direction perpendicular to the axis of the wheel axle 13. When the connector 163 slides along the axial direction of the wheel axle 13, the connector 163 can drive the two friction pads 1621 in the caliper 162 to slide synchronously along the axial direction of the wheel axle 13. Since the axial direction of the brake disc 161 is parallel to the axial direction of the wheel axle 13, the two friction pads 1621 can move along the axial direction of the brake disc 161, thereby allowing the two friction pads 1621 to float relative to the brake disc 161. This allows the two friction pads 1621 to fit more synchronously against the opposite sides of the brake disc 161, improving the overall service life of the caliper 162.

[0033] Specifically, when the two friction pads 1621 approach each other, if one friction pad 1621 contacts the brake disc 161 first, under the interaction force between the friction pad 1621 and the brake disc 161, the caliper 162 and the connecting member 163 will slide along the axial direction of the brake disc 161 until the other friction pad 1621 also contacts the brake disc 161. Afterwards, as the two friction pads 1621 continue to approach each other to clamp the brake disc 161, the caliper 162 and the connecting member 163 can still slide along the axial direction of the brake disc 161 under the coordination of the interaction forces between the two friction pads 1621 and the brake disc 161, until the interaction forces between the two friction pads 1621 and the brake disc 161 are closer to being equal. At this point, the two friction pads 1621... The center plane of the caliper 1621 is closer to coinciding with the center plane of the brake disc 161 along the axial direction. The pressure applied by the two friction pads 1621 to the brake disc 161 is closer to the same, resulting in more even friction on the two friction pads 1621. This makes the wear of the brake disc 161 more evenly distributed between the two friction pads 1621. After long-term use, the two friction pads 1621 are closer to reaching their service life at the same time, thereby improving the overall service life of the caliper 162. This avoids one friction pad 1621 reaching its service life prematurely due to longer wear than the other friction pad 1621, which would also cause the overall service life of the caliper 162 to reach its end prematurely. Furthermore, since the two friction pads 1621 cannot contact the brake disc 161 at the same time, the braking effect of the brake disc 161 is also poor.

[0034] In summary, in the motorcycle 100 provided in this application, the caliper 162 is fixedly mounted on the connector 163, and the connector 163 is sleeved on the wheel axle 13 and can slide along the axial direction of the wheel axle 13. This allows the two friction pads 1621 to move along the axial direction of the brake disc 161, thereby enabling the two friction pads 1621 to float relative to the brake disc 161. This makes the two friction pads 1621 fit more synchronously against the opposite sides of the brake disc 161, and also makes the friction between the two friction pads 1621 and the brake disc 161 more similar, thereby improving the overall service life of the caliper 162. Furthermore, since the caliper 162 is fixedly mounted on the connector 163, the floating structure of the caliper 162 is avoided, thus eliminating the need for a sliding pin structure. This allows it to adapt to situations where the radial space of the wheel axle 13 is small. In other words, the motorcycle 100 can reduce the radial space occupied by the wheel axle 13 through the braking assembly 16. Also, since the two friction pads 1621 can float, the brake disc 161 no longer needs to float. That is, the brake disc 161 can be fixed in position, avoiding the lateral floating structure of the brake disc 161. This allows the motorcycle 100 to adapt to situations where the diameter of the brake disc 161 is too small. Therefore, the motorcycle 100 provided in this application can achieve more uniform friction between the two friction pads 1621 and the brake disc 161 even when the brake disc diameter is too small and the radial space of the wheel axle is limited. This improves the overall service life of the caliper 162 and also enhances the braking effect of the brake disc 161.

[0035] In some embodiments, the running gear 12 includes at least two wheels, respectively located at the front and rear of the frame 11, forming the front and rear wheels of the motorcycle 100. The drive gear 15 includes at least a motor or engine for driving the front or rear wheel of the motorcycle 100 to rotate. The rocker arm 12 is rotatably connected to the rear of the frame 11 via a shock absorption system. The axle 13 is the rear wheel axle of the motorcycle 100 for supporting the rear wheel of the motorcycle 100. The braking gear 16 is used to brake the rear wheel of the motorcycle 100, wherein the brake disc 161 is connected to the rear wheel of the motorcycle 100 and rotates with the rear wheel of the motorcycle 100, and the caliper 162 brakes the rear wheel of the motorcycle 100 by friction against the brake disc 161. In other embodiments, the rocker arm 12 may also be located in front of the motorcycle 100, the axle 13 may be the front axle of the motorcycle 100, and the braking assembly 16 may be used to brake the front wheel of the motorcycle 100. Alternatively, at least two rocker arms 12 may be located in front of and behind the motorcycle 100, respectively. The axle 13 of the rocker arm 12 located in front may be the front axle of the motorcycle 100, and the axle 13 of the rocker arm 12 located behind may be the rear axle of the motorcycle 100. The braking assembly 16 located in front may be used to brake the front wheel of the motorcycle 100, and the braking assembly 16 located behind may be used to brake the rear wheel of the motorcycle 100.

[0036] Please refer to Figure 3 and Figure 4In some embodiments, the braking assembly 16 includes two limiting surfaces 164. The two limiting surfaces 164 are disposed facing each other and are located on opposite sides of the connector 163 along the axial direction of the wheel axle 13. The two limiting surfaces 164 are used to stop the connector 163 to limit the sliding distance of the connector 163, thereby limiting the movement distance of the two friction pads 1621.

[0037] Please refer to Figure 3 In some embodiments, the wheels in the walking assembly 14 are connected to rocker arms 12 on both sides to form a double rocker arm structure for the motorcycle. The two ends of the axle 13 are fixedly connected to the rocker arms 12, and the axle 13 does not rotate relative to the rocker arms 12. One rocker arm 12 forms a limiting surface 164 on its side facing the other rocker arm 12. The braking assembly 16 also includes a limiting bushing 165, which is sleeved on the outer periphery of the axle 13 and located between the two rocker arms 12. The side of the limiting bushing 165 facing the connector 163 forms another limiting surface 164. That is, the connector 163 slides between one rocker arm 12 and the limiting bushing 165. Since the axle 13 is fixed relative to the rocker arms 12 in the double rocker arm structure, the method of forming a limiting surface 164 between the rocker arms 12 and the limiting bushing 165 simplifies the structure of the braking assembly 16 and improves the assembly and disassembly efficiency of the motorcycle 100.

[0038] Alternatively, the braking assembly 16 may further include a sliding bushing 166, which is sleeved on the outer periphery of the wheel axle 13. The sliding bushing 166 is located between two limiting surfaces 164 formed by the rocker arm 12 and the limiting bushing 165. A connecting member 163 is sleeved on the outer periphery of the sliding bushing 166 and can slide along the sliding bushing 166. The side of the limiting bushing 165 facing away from the connecting member 163 is limited by a fixed bearing, while the side of the limiting bushing 165 facing the connecting member 163 is limited by the sliding bushing 166. The sliding bushing 166 ensures that the distance between the rocker arm 12 and the limiting bushing 165 is sufficient by its own length, thereby providing sufficient space for the connecting member 163 along the axial direction of the wheel axle 13, allowing the connecting member 163 to slide along the axial direction of the wheel axle 13. In addition, the sliding bushing 166 can reduce the friction between the connector 163 and the axle 13 and increase the operating speed of the two friction plates 1621. As an example, the sliding bushing 166 is made of a polymer material.

[0039] Alternatively, the braking assembly 16 may further include two flexible members 169. The connecting member 163 has a mounting groove 1631 on each opposite side along the axial direction of the wheel axle 13. The mounting grooves 1631 are arranged around the axis of the wheel axle 13. Each mounting groove 1631 is used to accommodate one flexible member 169. The flexible member 169 at least partially protrudes from the mounting groove 1631 to flexibly contact the limiting surface 164, avoiding excessive noise caused by hard contact between the connecting member 163 and the limiting surface 164, and also avoiding damage caused by hard contact between the connecting member 163 and the limiting surface 164. Specifically, the flexible member 169 on one side of the connecting member 163 is used to flexibly contact the limiting surface 164 formed by the rocker arm 12, and the flexible member 169 on the other side of the connecting member 163 is used to flexibly contact the limiting surface 164 formed by the limiting bushing 165. As an exemplary example, the flexible member 169 may be a sliding pad or a rubber ring, etc.

[0040] Alternatively, when the limiting surface 164 is formed on the rocker arm 12, the limiting surface 164 formed by the rocker arm 12 is not a complete plane because the surface of the rocker arm 12 has a groove or through hole, so the flexible member 169 cannot fully contact the limiting surface 164, or even cannot contact the limiting surface 164 at all, which may result in the flexible member 169 being partially or completely in an uncompressible suspended state. To ensure that the flexible member 169 can fully contact the limiting surface 164 and be evenly compressed, the braking assembly 16 further includes two ring plates 1691. The two ring plates 1691 are located on opposite sides of the connecting member 163 along the axial direction of the wheel axle 13. Each flexible member 169 is provided with a ring plate 1691 between it and the corresponding limiting surface 164. The outer diameter of the ring plate 1691 is larger than the outer diameter of the flexible member 169, so that the side of the ring plate 1691 facing the flexible member 169 can fully contact the flexible member 169. Furthermore, the side of the ring plate 1691 facing the limiting surface 164 can at least partially contact the limiting surface 164, thereby expanding the area of ​​the limiting surface 164. This allows the flexible member 169 to fully contact the limiting surface 164 through the ring plate 1691, ensuring that the flexible member 169 is evenly compressed and thus fully utilizing the function of the flexible member 169 in achieving soft contact between the connecting member 163 and the limiting surface 164. As an example, ring 1691 is a washer.

[0041] Alternatively, the flexible component 169 is always in contact with the corresponding limiting surface 164 after installation, so that the connector 163 can always achieve buffering by squeezing the flexible component 169 during the sliding process, ensuring that the constraint force between the parts is maintained and preventing vibration and abnormal noise caused by excessive gaps.

[0042] Understandably, in the double rocker arm structure, the axial length of the sliding bushing 166 is greater than the sum of the thickness of the connector 163 and the thickness of the two ring plates 1691, in order to provide clearance to allow the connector 163 to slide.

[0043] Please refer to Figure 4 In some embodiments, the wheel in the walking assembly 14 is connected to the rocker arm 12 on only one side to form a single-sided rocker arm structure for a motorcycle. Since in the single-sided rocker arm structure, the drive assembly 15 drives the walking assembly 14 by rotating the drive axle 13, the axle 13 needs to be rotatably connected to the rocker arm 12, rather than fixedly connected. In this case, to allow the connecting member 163 to slide along the axle 13, the braking assembly 16 also includes a fixing member 167. The fixing member 167 is sleeved on the outer periphery of the axle 13 and fixedly connected to the rocker arm 12. The connecting member 163 is sleeved on the outer periphery of the fixing member 167 and can slide along the fixing member 167. The fixing member 167 allows the connecting member 163 to slide without interfering with the rotation of the axle 13.

[0044] Alternatively, the fixing member 167 includes an inner section 1671 and an outer section 1672, which are arranged axially along the wheel axle 13. The cross-sectional dimension of the inner section 1671 is smaller than that of the outer section 1672. The connecting member 163 is sleeved on the outer periphery of the inner section 1671, and the end face of the outer section 1672 facing the inner section 1671 forms a limiting surface 164. Alternatively, the outer peripheral wall of the inner section 1671 is provided with a groove 1671a, and the braking assembly 16 also includes a stop member 168. The stop member 168 is disposed in the groove 1671a and at least partially protrudes from the groove 1671a. The side of the stop member 168 facing the connecting member 163 forms another limiting surface 164. That is, the connecting member 163 slides between the outer section 1672 and the stop member 168. As an exemplary example, the stop member 168 is a retaining ring. As an example, fastener 167 is an eccentric hub.

[0045] Alternatively, the connector 163 may also have mounting grooves 1631 and flexible members 169 on both sides. The flexible member 169 on one side of the connector 163 flexibly contacts the limiting surface 164 formed by the outer segment 1672, and the flexible member 169 on the other side of the connector 163 flexibly contacts the limiting surface 164 formed by the stop member 168. The flexible member 169 also prevents the connector 163 from making hard contact with the limiting surface 164, thus avoiding excessive noise and damage.

[0046] Alternatively, when the limiting surface 164 is formed on the fixing member 167, since the outer diameter of the stop member 168 may be smaller than the outer diameter of the flexible member 169, the flexible member 169 may not be able to contact the limiting surface 164, resulting in the flexible member 169 being partially or entirely in an uncompressible suspended state. In order to ensure that the flexible member 169 can fully contact the limiting surface 164 and that the flexible member 169 is evenly compressed, two annular pieces 1691 are also provided on both sides of the connecting member 163. Each flexible member 169 is provided with an annular piece 1691 between itself and the corresponding limiting surface 164. The outer diameter of the ring piece 1691 is larger than the outer diameter of the flexible member 169, so that the side of the ring piece 1691 facing the flexible member 169 can fully contact the flexible member 169. Furthermore, the side of the ring piece 1691 facing the limiting surface 164 can at least partially contact the limiting surface 164, so that the ring piece 1691 can expand the area of ​​the limiting surface 164. This allows the flexible member 169 to fully contact the limiting surface 164 through the ring piece 1691, and the flexible member 169 is uniformly pressed throughout, thereby fully utilizing the function of the flexible member 169 to achieve soft contact between the connector 163 and the limiting surface 164.

[0047] Understandably, in a single rocker arm structure, the distance from the end face of the outer section 1672 of the fixing member 167 to the stop member 168 is greater than the sum of the thickness of the connecting member 163 and the thickness of the two ring pieces 1691, in order to provide a clearance to allow the connecting member 163 to slide.

[0048] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
