Description

Technical Field

[0001] The utility model relates to the technical field of pedal silencing, in particular to a swing arm buffer positioning structure. Background Art

[0002] In the design of vehicle electric pedals, especially the structures involving the movement of the pedal swing arm, buffering and silencing are key factors in improving user experience, protecting mechanical components and extending the life of the equipment. Currently, many pedal swing arm systems rely solely on traditional buffering mechanisms, that is, buffering structures such as rubber and silicone are set between the swing arms to mitigate the impact force generated by the pedal during extension and retraction. However, the elastic properties of the buffering structures mean that they will absorb or disperse the driving force transmitted by the motor to a certain extent. When the electric pedal is extending or retracting, the buffering structure between the swing arms has a long buffering stroke, which may generate additional resistance or buffering effect, resulting in the pedal not being able to obtain sufficient driving force when approaching the target position, and thus failing to stop accurately at the predetermined position.

[0003] In the scenario where users actually use the vehicle's electric pedal, when the electric pedal approaches its extension end, if the buffer material absorbs the motor's driving force too early or excessively, the pedal will have difficulty overcoming the final resistance and will fail to fully extend to the designed position. Since the pedal is not firmly fixed in the predetermined position, users standing on the pedal are likely to feel a noticeable up and down shaking, which reduces the comfort and stability of getting on and off the vehicle. Utility Model Content

[0004] The utility model provides a swing arm buffer positioning structure to solve the problem that the buffer path of the buffer structure of the traditional pedal swing arm is too long, resulting in the pedal being unable to move to the correct position.

[0005] The present application provides a swing arm buffer positioning structure, including: a first swing arm and a second swing arm, the first swing arm and the second swing arm are used to swing the pedal connecting plate and install it on the bracket, and the first swing arm and the second swing arm can abut against each other during the swinging process; a buffer and a positioning member, the buffer and the positioning member are respectively installed on the first swing arm, and the buffer and the positioning member are located between the first swing arm and the second swing arm; the buffer is provided with a buffer surface, and the positioning member is provided with a positioning surface, and the buffer surface protrudes from the positioning surface, so that when the first swing arm and the second swing arm abut against each other, they are first buffered by the buffer surface and then positioned by the positioning surface; the buffer is made of soft material.

[0006] According to the above technical means, the design of the positioning member in the utility model effectively controls the soft contact stroke, avoiding insufficient extension or over-extension caused by excessive buffering. When the electric pedal approaches the target position, the positioning member can lightly touch the second swing arm to provide a stable blockage, ensuring that the pedal can accurately and stably stay in the set position, thereby improving the stability and safety of the entire system.

[0007] The buffer surface on the first swing arm of the utility model protrudes from the positioning surface. When the first swing arm and the second swing arm begin to approach each other, the buffer surface first contacts and absorbs part of the impact energy, reducing the force and speed of direct collision. Since the soft material has good buffering and shock absorption capabilities, this contact method can significantly reduce collision noise and vibration. As the swing arm continues to move, the second swing arm abuts the positioning surface, and the positioning surface provides a precise hard stop point for the extension movement of the electric pedal, effectively eliminating the extension distance difference that may be caused by the soft buffer, thereby ensuring that each pedal extension can accurately reach the predetermined position, greatly improving the reliability and repeatability of the system.

[0008] Furthermore, the buffer component also includes a buffer protrusion, and the buffer protrusion is arranged on the buffer surface.

[0009] According to the above technical means, the utility model adds a buffering protrusion on the buffering surface so that the buffering member forms a secondary buffering structure, which can more effectively absorb and disperse the impact force and reduce vibration and noise. Due to the increase in the local height of the buffering member, the second swing arm first contacts the buffering protrusion at the moment of contact, and the buffering protrusion absorbs and disperses the impact force to achieve the initial buffering. As the swing arm approaches further, the buffering surface contacts the second swing arm. On the basis of the initial buffering, an additional buffering effect is provided, which further slows down the relative movement speed between the swing arms and disperses the remaining impact force.

[0010] Furthermore, the number of the buffer protrusions is not less than two, and the buffer protrusions are evenly distributed on the buffer surface.

[0011] According to the above technical means, by increasing the number of buffering protrusions and distributing them evenly, it can be ensured that when the swing arms abut against each other, the impact force can be more evenly dispersed to the entire buffering surface, avoiding the problem of local stress concentration, making the buffering effect more stable and consistent.

[0012] Furthermore, the buffer component also includes a buffer component body, a first groove is formed on the first swing arm, and at least a part of the buffer component body is installed in the first groove; the buffer surface is arranged on a side of the buffer component body away from the first groove.

[0013] According to the above technical means, the first groove formed on the first swing arm provides a precise installation position for the buffer body. By at least partially embedding the buffer body into the groove, it can be ensured that the buffer will not shift during the swinging process, thereby maintaining its stability and reliability. At the same time, the buffer surface is arranged on the side of the buffer body away from the first groove, so that when the first swing arm and the second swing arm abut against each other, the buffer surface can directly contact the second swing arm and play a buffering role. Since the buffer body is firmly installed in the first groove, it can better absorb and disperse the impact force, thereby improving the buffering effect.

[0014] Furthermore, a first limiting member is formed on the buffer body, and a second limiting member is arranged on the positioning member. The first limiting member is matched with the second limiting member so that the positioning member can fix the buffer on the first swing arm.

[0015] According to the above technical means, the first limit member and the second limit member in the utility model cooperate with each other to form an effective fixing mechanism, ensuring that the buffer body can be firmly installed in the first groove, thereby improving the reliability and durability of the entire buffer positioning structure.

[0016] Furthermore, the positioning member also includes a second buffer body, a second groove is formed on the first swing arm, and at least part of the positioning member body is installed in the second groove; the positioning surface and the second limiting member are respectively arranged on the buffer body, and the positioning surface and the second limiting member are located outside the second groove.

[0017] According to the above technical means, the second buffer body is partially embedded in the second groove on the first swing arm, ensuring that the positioning member will not fall off or shift during the swinging process. Since the positioning surface is located outside the second groove, it can directly contact the second swing arm to achieve accurate positioning. Similarly, since the second limiter is also located outside the second groove, it can effectively contact and lock with the first limiter on the buffer.

[0018] Furthermore, it also includes a fixing member, and the positioning member body is installed on the first swing arm through the fixing member.

[0019] According to the above technical means, the positioning member body is firmly fixed at a predetermined position on the first swing arm through the tightening action of the fixing member, thereby preventing it from loosening or falling off during the swinging process.

[0020] Furthermore, a third groove and a through hole are formed on the positioning member, the third groove is arranged on the positioning member body, and the through hole is located at the bottom of the third groove; the fixing member passes through the through hole and is fixed on the first swing arm to fix the positioning member body on the first swing arm.

[0021] According to the above technical means, the third groove is used to accommodate a part of the fixing piece so as to provide additional support and positioning during the fixing process. The through hole is a hole located at the bottom of the third groove and passes through the positioning piece body, so that the fixing piece can pass through the through hole and be fixed on the first swing arm, thereby improving the overall stability and reliability of the buffer positioning structure.

[0022] Furthermore, the first limiting member is a limiting step, and the second limiting member is a limiting block.

[0023] According to the above technical means, the limiting block matches the shape of the limiting step, and the limiting block can be accurately embedded in the limiting step to achieve a stable fixing effect.

[0024] Furthermore, it comprises two buffer members, which are symmetrically installed on both sides of the positioning member.

[0025] According to the above technical means, two buffer members symmetrically installed on both sides of the positioning member can provide a balanced and stable buffering effect during the arm swinging process.

[0026] Beneficial effects:

[0027] The design of the positioning member in the utility model effectively controls the soft contact stroke, avoiding insufficient extension or overextension caused by excessive buffering. When the electric pedal approaches the target position, the positioning member can lightly touch the second swing arm to provide a solid blockage, ensuring that the pedal can accurately and stably stay in the set position, thereby improving the stability and safety of the entire system.

[0028] The buffer surface on the first swing arm of the utility model protrudes from the positioning surface. When the first swing arm and the second swing arm begin to approach each other, the buffer surface first contacts and absorbs part of the impact energy, reducing the force and speed of direct collision. Since the soft material has good buffering and shock absorption capabilities, this contact method can significantly reduce collision noise and vibration. As the swing arm continues to move, the second swing arm abuts the positioning surface, and the positioning surface provides a precise hard stop point for the extension movement of the electric pedal, effectively eliminating the extension distance difference that may be caused by the soft buffer, thereby ensuring that each pedal extension can accurately reach the predetermined position, greatly improving the reliability and repeatability of the system.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0048] like Figure 1 and Figure 2 As shown, the present embodiment provides a swing arm buffer positioning structure, comprising: a first swing arm 1 and a second swing arm 2, wherein the first swing arm 1 and the second swing arm 2 are used to swingably mount the pedal connecting plate 3 on the bracket 4, and the first swing arm 1 and the second swing arm 2 can abut against each other during the swinging process; a buffer 5 and a positioning member 6, wherein the buffer 5 and the positioning member 6 are respectively mounted on the first swing arm 1, and the buffer 5 and the positioning member 6 are located between the first swing arm 1 and the second swing arm 2; a buffer surface 51 is provided on the buffer 5, and a positioning surface 61 is provided on the positioning member 6, and the buffer surface 51 protrudes from the positioning surface 61, so that when the first swing arm 1 and the second swing arm 2 abut against each other, they are first buffered by the buffer surface 51 and then positioned by the positioning surface 61; the buffer 5 is made of soft material.

[0049] like Figure 2 , Figure 4 and Figure 5 As shown, during the installation process, the first swing arm 1 and the second swing arm 2 are accurately installed on the bracket 4 according to the design requirements, ensuring that the two can swing freely around their respective fulcrums, and at the same time ensuring that the pedal connecting plate 3 can be firmly connected to the two swing arms. The buffer 5 and the positioning member 6 are installed at the appropriate position of the first swing arm 1. The buffer 5 should ensure that its buffer surface 51 faces the direction that the second swing arm 2 may contact, and protrudes beyond the positioning surface 61, so as to play a buffering role first when contacting.

[0050] During specific use, as the first swing arm 1 and the second swing arm 2 swing, when the first swing arm 1 gradually approaches the second swing arm 2, the gap between the two gradually decreases until the buffer surface 51 on the first swing arm 1 first contacts the second swing arm 2. Since the buffer 5 is made of soft materials, such as rubber, silicone, etc., it can effectively absorb and disperse the impact force, reduce the vibration and noise generated by the direct collision of the two swing arms, and protect the entire mechanism from damage. As the swing continues, when the buffer 5 is compressed to a certain extent, the positioning surface 61 thereafter begins to contact the second swing arm 2. At this time, the positioning surface 61 acts as a hard contact point, providing precise positioning for the swing arm, ensuring that the pedal connecting plate 3 can stay in the predetermined position.

[0051] The design of the positioning member 6 in this embodiment effectively controls the soft contact stroke, avoiding insufficient extension or over-extension caused by excessive buffering. When the electric pedal approaches the target position, the positioning member 6 can lightly touch the second swing arm to provide a stable blockage, ensuring that the pedal can accurately and stably stay at the set position, thereby improving the stability and safety of the entire system.

[0052] In this embodiment, the buffer surface 51 on the first swing arm 1 protrudes from the positioning surface 61. When the first swing arm 1 and the second swing arm 2 begin to approach each other, the buffer surface 51 first contacts and absorbs part of the impact energy, reducing the force and speed of direct collision. Since the soft material has good buffering and shock absorption capabilities, this contact mode can significantly reduce collision noise and vibration. As the swing arm continues to move, the second swing arm 2 abuts the positioning surface 61, and the positioning surface 61 provides a precise hard stop point for the extension movement of the electric pedal, effectively eliminating the extension distance difference that may be caused by the soft buffer 5, thereby ensuring that each pedal extension can accurately reach the predetermined position, greatly improving the reliability and repeatability of the system.

[0053] In this embodiment, the positioning member 6 is preferably made of hard material, such as metal (stainless steel, aluminum alloy, etc.) or hard plastic (nylon, polycarbonate, etc.). These materials have high strength, high rigidity and wear resistance, and can ensure stable and accurate positioning when the swing arms abut against each other.

[0054] like Figure 2 and Figure 3 As shown, the buffer member 5 further includes a buffer protrusion 52 , and the buffer protrusion 52 is arranged on the buffer surface 51 .

[0055] In this embodiment, a buffering protrusion 52 is added to the buffering surface 51 so that the buffering member 5 forms a secondary buffering structure, which can more effectively absorb and disperse the impact force and reduce vibration and noise. Since the height of the buffering member 5 is increased locally, the second swing arm 2 first contacts the buffering protrusion 52 at the moment of contact, and the buffering protrusion 52 absorbs and disperses the impact force to achieve the initial buffering. As the swing arm approaches further, the buffering surface 51 contacts the second swing arm 2. On the basis of the initial buffering, an additional buffering effect is provided, which further slows down the relative movement speed between the swing arms and disperses the remaining impact force.

[0056] In this embodiment, the buffer protrusion 52 is in a hemispherical shape, and the hemispherical shape has a smooth curved surface. When in contact with the second swing arm 2, the impact force can be more effectively dispersed to a larger area, reducing the pressure per unit area and reducing the risk of local stress concentration. The hemispherical buffer protrusion 52 can gradually compress and release energy during the contact process. This gradual compression process helps to reduce sudden impact sound and vibration, making the energy transfer more stable, thereby improving the stability of the buffer 5.

[0057] like Figure 2 and Figure 3 As shown, the number of the buffer protrusions 52 is not less than two, and the buffer protrusions 52 are evenly distributed on the buffer surface 51 .

[0058] By increasing the number of buffering protrusions 52 and distributing them evenly, it can be ensured that when the swing arms abut against each other, the impact force can be more evenly dispersed to the entire buffering surface 51, avoiding the problem of local stress concentration, making the buffering effect more stable and consistent.

[0059] like Figure 2 and Figure 3 As shown, the buffer 5 also includes a buffer body 53, a first groove 11 is formed on the first swing arm 1, and at least part of the buffer body 53 is installed in the first groove 11; the buffer surface 51 is arranged on the side of the buffer body 53 away from the first groove 11.

[0060] The first groove 11 formed on the first swing arm 1 provides a precise installation position for the buffer body 53. By at least partially embedding the buffer body 53 into the groove, it can be ensured that the buffer 5 will not shift during the swinging process, thereby maintaining its stability and reliability. At the same time, the buffer surface 51 is arranged on the side of the buffer body 53 away from the first groove 11, so that when the first swing arm 1 and the second swing arm 2 abut against each other, the buffer surface 51 can directly contact the second swing arm 2 and play a buffering role. Since the buffer body 53 is firmly installed in the first groove 11, it can better absorb and disperse the impact force, thereby improving the buffering effect.

[0061] In order to ensure the installation stability of the buffer body 53 , the buffer body 53 may be fixed in the first groove 11 by using an appropriate fixing method (such as bonding, screw fixing, or snap connection, etc.).

[0062] Preferably, in this embodiment, a first limit member 54 is formed on the buffer body 53, and a second limit member 62 is provided on the positioning member 6. The first limit member 54 is adapted to the second limit member 62 so that the positioning member 6 can fix the buffer 5 on the first swing arm 1.

[0063] like Figure 2 As shown, in this embodiment, the first limit member 54 and the second limit member 62 cooperate with each other to form an effective fixing mechanism, ensuring that the buffer body 53 can be firmly installed in the first groove 11, thereby improving the reliability and durability of the entire buffer positioning structure.

[0064] like Figure 1 and Figure 2 As shown, the positioning member 6 also includes a second buffer body 63, a second groove 12 is formed on the first swing arm 1, and at least part of the positioning member body 63 is installed in the second groove 12; the positioning surface 61 and the second limiting member 62 are respectively arranged on the buffer body 53, and the positioning surface 61 and the second limiting member 62 are located outside the second groove 12.

[0065] The second buffer body 63 is partially embedded in the second groove 12 on the first swing arm 1, ensuring that the positioning member 6 will not fall off or shift during the swinging process. Since the positioning surface 61 is located outside the second groove 12, it can directly contact the second swing arm 2 to achieve an accurate positioning function. Similarly, since the second stopper 62 is also located outside the second groove 12, it can effectively contact and lock with the first stopper 54 on the buffer member 5.

[0066] like Figure 1 and Figure 2 As shown, a fixing member 7 is also included, and the positioning member body 63 is installed on the first swing arm 1 through the fixing member 7.

[0067] Through the fastening effect of the fixing member 7, the positioning member body 63 is firmly fixed at a predetermined position on the first swing arm 1, thereby preventing it from loosening or falling off during the swinging process.

[0068] like Figure 1 and Figure 2As shown, a third groove 64 and a through hole 65 are formed on the positioning member 6, the third groove 64 is arranged on the positioning member body 63, and the through hole 65 is located at the bottom of the third groove 64; the fixing member 7 passes through the through hole 65 and is fixed on the first swing arm 1 to fix the positioning member body 63 on the first swing arm 1.

[0069] The third groove 64 is used to accommodate a portion of the fixing member 7 so as to provide additional support and positioning during the fixing process. The through hole 65 is a hole located at the bottom of the third groove 64 and passes through the positioning member body 63, so that the fixing member 7 can pass through the through hole 65 and be fixed on the first swing arm 1, thereby improving the overall stability and reliability of the buffer positioning structure.

[0070] In this embodiment, the diameter and shape of the through hole 65 need to match the fixing member 7 to ensure that the fixing member 7 can pass through smoothly and be tightly fixed in place. The fixing member 7 is a screw, bolt, pin, buckle or other fastening structure.

[0071] like Figure 1 and Figure 2 As shown, the first limiting member 54 is a limiting step, and the second limiting member 62 is a limiting block.

[0072] The limiting block matches the shape of the limiting step, and the limiting block can be accurately embedded in the limiting step to achieve a stable fixing effect.

[0073] like Figure 1 and Figure 2 As shown, the swing arm buffer positioning structure includes two buffer members 5, and the two buffer members 5 are symmetrically installed on both sides of the positioning member 6. The two buffer members 5 are symmetrically installed on both sides of the positioning member 6 to provide a balanced and stable buffering effect during the swing arm process.

[0074] The above embodiments are only preferred embodiments for fully illustrating the present embodiment, and the protection scope of the present embodiment is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present embodiment shall be within the protection scope of the present embodiment.
