Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and in particular to a steering device and a scooter. Background Art

[0002] Currently, steering damping for two-wheeled vehicles like bicycles and scooters is primarily achieved using damping oil. This approach involves filling the space between the steering column and the head tube, leveraging the oil's viscous resistance to suppress oversteer and improve vehicle stability. However, this damping oil solution has limitations. Its friction is typically fixed, making it difficult to adjust in real time based on actual riding conditions.

[0003] Therefore, in the prior art, the damping can be adjusted by setting a damping adjuster, which generally adopts a method of cooperating multiple wedge blocks, screws and damping blocks to achieve damping adjustment. For example, Chinese patent publication number CN218703701U discloses a scooter, in which the guide block 2 is displaced by rotating the adjusting bolt 1. Under the action of the guide surface 1 and the guide surface 2, the guide block 2 can be pushed downward to adjust the pressure of the damping block against the upper side plane of the front end of the frame. The corresponding friction force changes accordingly, that is, the steering resistance can be adjusted. In the above method, although a certain degree of friction adjustment can be provided, the structure is relatively complicated because it involves more parts. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a steering device and a scooter.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by one embodiment of the present invention is as follows:

[0006] A steering device comprises: a head pipe assembly; a steering assembly passing through the head pipe assembly; and a damping assembly disposed on the outer periphery of the steering assembly, wherein the steering assembly and the damping assembly are configured to rotate synchronously relative to the head pipe assembly; wherein the damping assembly comprises an adjusting member and a friction member, wherein the friction member is capable of abutting against the head pipe assembly to generate friction, and wherein the adjusting member is movably disposed relative to the steering assembly along the axial direction of the steering assembly to adjust the friction between the friction member and the head pipe assembly.

[0007] In the above technical solution, the adjustment member and the friction member in the damping assembly work together. By moving the adjustment member along the axial direction L, the friction member can be brought into contact with the head pipe assembly and generate friction, thereby providing a damping effect for the steering operation of the steering assembly, and by moving the adjustment member closer to or farther away from the head pipe assembly along the axial direction L, the contact degree and contact pressure between the friction member and the head pipe assembly can be adjusted. In this way, compared with the fixed friction force based on damping oil and the damping adjustment structure using multiple wedge blocks and screws in the prior art, in the present application, the contact pressure of the friction member is directly changed by using the movement of the adjustment member, which not only can adjust the friction force between the friction member and the head pipe assembly in real time according to actual riding conditions, thereby improving the vehicle's handling and stability, but also reduces the number of parts and simplifies the linkage structure, thereby achieving simplification in the damping adjustment structure, reducing assembly difficulty, and reducing production costs.

[0008] In some embodiments, the adjusting member is rotatably disposed relative to the steering assembly, and the adjusting member can be moved along the axial direction by screwing the adjusting member.

[0009] In the above technical solution, by rotating the adjustment member to achieve its movement along the axial direction L, the friction member can be moved closer to the head pipe assembly to generate damping, or the friction member can be moved away from the head pipe assembly to eliminate damping. Moreover, after the friction member contacts the head pipe assembly, the contact pressure between the friction member and the head pipe assembly can be changed. In this way, when the user needs to adjust the steering damping, they only need to rotate the adjustment member to increase or decrease the damping, which is convenient to operate. Therefore, the above adjustment process is simple and quick, and the damping adjustment can be completed without additional tools.

[0010] In some embodiments, an adjustment member is used to compress the friction member against the head pipe assembly, and the adjustment member is threadably engaged with an outer periphery of the steering assembly.

[0011] In the above technical solution, on the one hand, the transmission characteristics of the thread are utilized, and the adjustment member can be moved along the axial direction by rotating it, thereby changing the contact pressure between the friction member and the head pipe assembly, which is not only convenient for adjustment but also simple in structure; on the other hand, the self-locking characteristics of the thread are utilized, and when the adjustment member moves along the axial direction, the pressing force can be stably applied to the friction member, ensuring that the friction force between the friction member and the head pipe assembly is adjustable and stable; on the other hand, by adopting the threaded fitting method, stepless adjustment of the damping can be achieved.

[0012] In some embodiments, the friction member is made of a rigid material and is slidably matched with the steering assembly. When the adjustment member is moved, the friction member gradually approaches the head pipe assembly along the axial direction until the friction member abuts against the head pipe assembly.

[0013] In the above technical solution, the movement of the adjusting member can drive the friction member to move toward the direction of the head pipe assembly, so that the friction member first contacts the head pipe assembly. Then, continuing to move the adjusting member in the same direction can make the friction member abut against the head pipe assembly and increase the contact pressure between the friction member and the head pipe assembly, thereby adjusting the friction force. Moving the adjusting member in the opposite direction can first reduce the contact pressure between the friction member and the head pipe assembly. Then, continuing to move the adjusting member in the opposite direction can make the friction member move away from the head pipe assembly, that is, the friction member and the head pipe assembly are not in contact.

[0014] In some embodiments, the friction member contacts the head pipe assembly and is made of an elastic material. The adjusting member is moved to cause the friction member to deform and abut against the head pipe assembly.

[0015] In the above manner, the friction member deforms but does not move along the axial direction L. In this way, the deformation characteristics of the elastic material can be utilized to adjust the movement of the member to cause the friction member to deform, thereby increasing the contact pressure with the head pipe assembly, thereby increasing the friction; alternatively, the contact pressure with the head pipe assembly can be reduced, thereby reducing the friction; in this way, the steering damping adjustment can be made softer, providing a more comfortable riding experience.

[0016] In some embodiments, the friction member is made of elastic material and is slidably matched with the steering assembly. When the adjustment member is moved, the friction member gradually approaches the head pipe assembly along the axial direction until the friction member is deformed and abuts against the head pipe assembly.

[0017] In the above manner, the friction member both deforms and moves. Thus, by moving the adjusting member, the friction member can first be brought close to the head pipe assembly until it contacts the head pipe assembly. At this point, friction begins to be generated between the friction member and the head pipe assembly. Then, by continuing to move the adjusting member, the friction member gradually deforms, thereby changing the friction between the friction member and the head pipe assembly.

[0018] In some embodiments, the damping assembly further includes an elastic member abutting between the friction member and at least a portion of the adjustment member.

[0019] In the above technical solution, when the user rotates the adjustment member toward the head tube assembly, the elastic member is compressed, thereby increasing the contact pressure between the friction member and the head tube assembly. Similarly, when the user rotates the adjustment member away from the head tube assembly, the elastic member is released, thereby reducing the contact pressure between the friction member and the head tube assembly. The elastic member can provide a cushioning effect. Thus, on the one hand, it ensures stable contact between the friction member and the head tube assembly, maintaining stable friction even during rapid or large steering movements, thereby avoiding sudden changes and discomfort during steering and ensuring smoother steering. On the other hand, the cushioning effect of the elastic member between the adjustment member and the friction member reduces hard collisions during direct contact between the two, effectively preventing the occurrence of sticking, thereby improving the smoothness of the adjustment process and making it easier for the user to adjust the steering damping. On the other hand, when the friction member contacts the head tube assembly, the cushioning effect of the elastic member reduces wear on the friction surface and avoids damage caused by hard contact, thereby significantly extending the service life of the friction member and the head tube assembly, reducing maintenance costs, and improving the durability of the entire steering device.

[0020] In some embodiments, the elastic member includes any one of a wave washer, a spring, and a rubber ring.

[0021] In this way, the characteristics of different types of elastic components can be utilized to provide diverse damping adjustment methods to adapt to the preferences of different users and the structural requirements of different vehicles.

[0022] In some embodiments, a mounting groove is provided on a side of the adjustment member facing the head pipe assembly, and one end of the friction member is mounted in the mounting groove along the axial direction, while the other end of the friction member protrudes from or is flush with the adjustment member.

[0023] In the above technical solution, the friction member can be installed by setting the installation groove, and at the same time, the protruding or flush design of the friction member can achieve effective contact with the head pipe assembly, so that friction can be generated between the friction member and the head pipe assembly.

[0024] In some embodiments, an avoidance groove is provided on a side of the adjustment member facing away from the head pipe assembly along the axial direction.

[0025] In this way, the connection position between the front fork and the steering assembly can be avoided, which not only prevents the above-mentioned connection position from interfering with the rotation of the adjustment component to ensure a smooth adjustment process, but also maintains the aesthetics of the steering device.

[0026] In some embodiments, the steering device further includes a front fork, which is welded to the outer periphery of the steering assembly, and the avoidance groove is used to accommodate the weld between the front fork and the steering assembly.

[0027] In this way, by setting the avoidance groove, it is ensured that the adjusting component will not interfere with the weld during rotation, so that the steering damping adjustment is smoother. At the same time, the weld is accommodated in the avoidance groove, which also improves the overall aesthetics of the steering device.

[0028] In some embodiments, a mounting through hole is provided on the friction member, at least one first stop-rotation portion is provided on the inner wall of the mounting through hole, at least one second stop-rotation portion is provided on the outer periphery of the steering assembly, at least one first stop-rotation portion and at least one second stop-rotation portion are arranged in a one-to-one correspondence, and the mounting through hole is engaged with the second stop-rotation portion through the first stop-rotation portion.

[0029] In the above technical solution, the cooperation of the first anti-rotation portion and the second anti-rotation portion can prevent relative rotation between the friction member and the steering assembly. In this way, when the steering assembly rotates relative to the head pipe assembly, the friction member can be rotated relative to the head pipe assembly, thereby generating friction damping between the friction member and the head pipe assembly.

[0030] In some embodiments, the first anti-rotation portion is a flat anti-rotation surface, and the second anti-rotation portion is a flat anti-rotation surface; alternatively, the first anti-rotation portion is a protrusion, and the second anti-rotation portion is a groove; alternatively, the first anti-rotation portion is a groove, and the second anti-rotation portion is a protrusion. In this way, the friction member and the steering assembly can be prevented from rotating, thereby generating frictional damping between the friction member and the head pipe assembly.

[0031] In some embodiments, the steering assembly includes a rotating tube and a folding seat connected to the rotating tube, the steering device also includes a front fork mounted on the outer periphery of the rotating tube, and the head tube assembly is located between the folding seat and the front fork; a damping assembly is provided between the head tube assembly and the front fork; and / or, a damping assembly is provided between the head tube assembly and the folding seat; wherein, the head tube assembly includes a head tube and a bowl group, a bowl group is provided at the end of the head tube, and the friction member can abut against at least one of the head tube and the bowl group.

[0032] In the above technical solution, by integrating the damping assembly into the structure of the steering device, that is, arranging the damping assembly between the head tube assembly and the front fork, and / or arranging the damping assembly between the head tube assembly and the folding seat, the aesthetic problem caused by the external steering damper can be solved, so as to avoid the damper being exposed and affecting the neatness of the vehicle appearance.

[0033] In some embodiments, bowl sets are provided at both ends of the head tube along the axial direction, and the rotating tube is rotatably arranged in the head tube through the two bowl sets; wherein, when a damping assembly is provided between the head tube assembly and the front fork, the friction member can abut against the bowl set located on the side of the head tube facing the front fork; when a damping assembly is provided between the head tube assembly and the folding seat, the friction member can abut against the bowl set located on the side of the head tube facing the folding seat.

[0034] In the above technical solution, by arranging bowl groups at both ends of the head pipe, the stable rotation of the steering assembly in the head pipe can be ensured. At the same time, the setting position of the damping assembly can be adjusted according to actual needs, thereby improving the flexibility of steering damping adjustment.

[0035] In some embodiments, the steering assembly includes a rotating tube and a mounting tube connected to the rotating tube, the damping assembly is mounted on the outer periphery of the mounting tube, and the adjusting member is movably disposed on the outer periphery of the mounting tube. This facilitates processing.

[0036] In some embodiments, the rotating tube and the mounting barrel are integrally formed, which reduces the number of assembly steps and facilitates assembly.

[0037] A scooter comprises a frame and the above-mentioned steering device. The head pipe assembly comprises a head pipe, and the head pipe is fixedly connected to the frame or integrally formed.

[0038] The present invention has the following beneficial effects: the adjustment member and the friction member in the damping assembly work together, and by moving the adjustment member along the axial direction L, the friction member can be brought into contact with the head pipe assembly and generate friction, thereby providing a damping effect for the steering operation of the steering assembly, and by moving the adjustment member closer to or farther away from the head pipe assembly along the axial direction L, the contact degree and contact pressure between the friction member and the head pipe assembly can be adjusted. In this way, compared with the damping adjustment structure in the prior art that uses fixed friction based on damping oil and adopts multiple wedge blocks and screws, in the present application, the contact pressure of the friction member is directly changed by using the movement of the adjustment member, which not only can adjust the friction between the friction member and the head pipe assembly in real time according to actual riding conditions, thereby improving the vehicle's handling and stability, but also reduces the number of parts and simplifies the linkage structure, thereby achieving simplification in the damping adjustment structure, reducing assembly difficulty, and reducing production costs.

[0053] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0054] The technical solution of the present invention will be described below with reference to the accompanying drawings.

[0055] In order to solve the problem of a relatively complex structure of a steering damping adjustment device of a scooter in the prior art, the present invention provides a steering device and a scooter.

[0056] In some embodiments, as Figures 1 to 4 As shown, the scooter includes a frame 1 and a steering device, the steering device includes a head pipe assembly 10, a steering assembly 20 and a damping assembly 30, the head pipe assembly 10 includes a head pipe 11, and the head pipe 11 is fixedly connected to the frame 1 or integrally formed.

[0057] The steering device and the scooter are described in detail below.

[0058] It should be noted that if Figure 3 As shown, the axial direction L is the direction of the axis L of the steering assembly.

[0059] In some embodiments, as Figures 1 to 4As shown, an embodiment of the present invention provides a steering device. The steering device includes: a head pipe assembly 10; a steering assembly 20 disposed through the head pipe assembly 10; and a damping assembly 30 disposed on the periphery of the steering assembly 20. The steering assembly 20 and the damping assembly 30 are configured to rotate synchronously relative to the head pipe assembly 10. The damping assembly 30 includes an adjustment member 31 and a friction member 32. The friction member 32 is capable of abutting against the head pipe assembly 10 to generate friction. The adjustment member 31 is movably disposed relative to the steering assembly 20 along the axial direction L of the steering assembly 20 to adjust the friction between the friction member 32 and the head pipe assembly 10.

[0060] In the above technical solution, the adjustment member 31 and the friction member 32 in the damping assembly 30 work together. By moving the adjustment member 31 along the axial direction L, the friction member 32 can be brought into contact with the head pipe assembly 10 and generate friction, thereby providing a damping effect for the steering operation of the steering assembly 20. By moving the adjustment member 31 closer to or farther away from the head pipe assembly 10 along the axial direction L, the contact degree and contact pressure between the friction member 32 and the head pipe assembly 10 can be adjusted. In this way, compared with the damping adjustment structure in the prior art that uses fixed friction force based on damping oil and adopts multiple wedge blocks and screws, in the present application, the contact pressure of the friction member 32 is directly changed by using the movement of the adjustment member 31. This not only allows the friction between the friction member 32 and the head pipe assembly 10 to be adjusted in real time according to actual riding conditions, thereby improving the vehicle's handling and stability, but also reduces the number of parts and simplifies the linkage structure, thereby achieving simplification in the damping adjustment structure, reducing assembly difficulty, and reducing production costs.

[0061] In some embodiments, as Figures 1 to 4 As shown, the adjusting member 31 is rotatably provided relative to the steering assembly 20 , and the adjusting member 31 can be moved along the axial direction L by screwing the adjusting member 31 .

[0062] In the above technical solution, by rotating the adjustment member 31 to achieve its movement along the axial direction L, the friction member 32 can be moved closer to the head pipe assembly 10 to generate damping, or the friction member 32 can be moved away from the head pipe assembly 10 to eliminate damping. After the friction member 32 contacts the head pipe assembly 10, the contact pressure between the friction member 32 and the head pipe assembly 10 can be changed. In this way, when the user needs to adjust the steering damping, he only needs to rotate the adjustment member 31 to increase or decrease the damping, which is easy to operate. Therefore, the above adjustment process is simple and quick, and the damping adjustment can be completed without additional tools.

[0063] Of course, in another embodiment not shown in the figure, a locking through hole can also be provided on the adjusting member 31, and a plurality of threaded holes can be provided on the steering assembly 20, and the plurality of threaded holes can be spaced apart along the axial direction L. After the adjusting member 31 is moved to the desired position, the screw is passed through the mounting through hole and threadedly engaged with one of the plurality of threaded holes to fix the adjusting member 31.

[0064] In some embodiments, as Figure 3 and Figure 4 As shown, the adjusting member 31 is used to press the friction member 32 against the head pipe assembly 10 , and the adjusting member 31 is threadedly engaged with the outer periphery of the steering assembly 20 .

[0065] In the above technical solution, on the one hand, the transmission characteristics of the thread are utilized, and the adjustment member 31 can be rotated to achieve its movement along the axial direction, thereby changing the contact pressure between the friction member 32 and the head pipe assembly 10, which is not only convenient for adjustment but also simple in structure; on the other hand, the self-locking characteristics of the thread are utilized, and when the adjustment member 31 moves along the axial direction, the pressing force can be stably applied to the friction member 32, ensuring that the friction force between the friction member 32 and the head pipe assembly 10 is adjustable and stable; on the other hand, by adopting the threaded fitting method, the damping can be infinitely adjusted.

[0066] Of course, in another embodiment (not shown), the adjustment member 31 can also be rotationally engaged with the steering assembly 20 and axially constrained thereto. The outer wall of the friction member 32 is provided with external threads, and the adjustment member 31 is provided with a mounting groove 311. The circumferential inner wall of the mounting groove 311 is provided with internal threads, and the internal threads and the external threads mate with each other. In this way, the friction member 32 can be directly moved by turning the adjustment member 31. That is, the adjustment member 31 does not move along the axial direction L, but the friction member 32 moves along the axial direction L, thereby varying the friction force between the friction member 32 and the head pipe assembly 10.

[0067] In some embodiments, as Figure 3 and Figure 4 As shown, the friction member 32 is made of a rigid material and is slidably matched with the steering assembly 20 . When the adjustment member 31 is moved, the friction member 32 gradually approaches the head pipe assembly 10 along the axial direction L until the friction member 32 abuts against the head pipe assembly 10 .

[0068] In the above technical solution, the movement of the adjusting member 31 can drive the friction member 32 to move toward the direction of the head pipe assembly 10, so that the friction member 32 first contacts the head pipe assembly 10, and then the adjusting member 31 is continued to move in the same direction, so that the friction member 32 can abut against the head pipe assembly 10 and increase the contact pressure between the friction member 32 and the head pipe assembly 10, thereby adjusting the friction force; the adjusting member 31 is moved in the opposite direction to first reduce the contact pressure between the friction member 32 and the head pipe assembly 10, and then the adjusting member 31 is continued to move in the opposite direction to move the friction member 32 away from the head pipe assembly 10, that is, the friction member 32 and the head pipe assembly 10 are not in contact.

[0069] Of course, in another embodiment (not shown), the friction member 32 is in contact with the head pipe assembly 10 and is made of an elastic material. The adjustment member 31 is moved to deform the friction member 32 and cause it to abut the head pipe assembly 10. In this embodiment, the friction member 32 deforms but does not move along the axial direction L. This allows the elastic material's deformable properties to be utilized, and the movement of the adjustment member 31 can cause the friction member 32 to deform, thereby increasing the contact pressure with the head pipe assembly 10 and thereby increasing friction; alternatively, the contact pressure with the head pipe assembly 10 can be reduced, thereby reducing friction. This allows for smoother steering damping adjustment, providing a more comfortable riding experience.

[0070] Of course, in another embodiment (not shown), the friction member 32 is made of an elastic material, and the friction member 32 is slidably engaged with the steering assembly 20. By moving the adjustment member 31, the friction member 32 gradually approaches the head pipe assembly 10 along the axial direction L until the friction member 32 deforms and abuts the head pipe assembly 10. In this manner, the friction member 32 both deforms and moves. Thus, by moving the adjustment member 31, the friction member 32 can first approach the head pipe assembly 10 until it contacts the head pipe assembly 10. At this point, friction begins to be generated between the friction member 32 and the head pipe assembly 10. Then, by continuing to move the adjustment member 31, the friction member 32 gradually deforms, thereby varying the friction between the friction member 32 and the head pipe assembly 10.

[0071] In some embodiments, as Figure 5 As shown, an elastic member 34 can be provided between the headset 12 of the head pipe assembly 10 and the friction member 32. In this way, the friction member 32 can be fixed to the adjustment member 31 and the elastic member 34, and a gap can be created between the friction member 32 and the headset 12. The friction member 32 can then be subsequently moved to bring the friction member 32 closer to the headset 12 and compress the elastic member 34 until the friction member 32 abuts against the headset 12. The friction force between the friction member 32 and the headset 12 can then be adjusted by moving the adjustment member 31. The elastic member 34 is a spring.

[0072] In some embodiments, as Figure 3 and Figure 4 As shown, the damping assembly 30 further includes an elastic member 33 , which abuts between the friction member 32 and at least a portion of the adjustment member 31 .

[0073] In the above technical solution, when the user rotates the adjusting member 31 to move the adjusting member 31 toward the head tube assembly 10, the elastic member 33 is compressed, which can increase the contact pressure between the friction member 32 and the head tube assembly 10; similarly, when the user rotates the adjusting member 31 to move the adjusting member 31 away from the head tube assembly 10, the elastic member 33 is released, which can reduce the contact pressure between the friction member 32 and the head tube assembly 10; wherein the elastic member 33 can achieve a buffering effect, thus, on the one hand, ensuring that the friction member 32 and the head tube assembly 10 can be in stable contact, and even in fast or large-scale steering, stable friction can be maintained, thereby avoiding On the other hand, the elastic member 33 acts as a buffer between the adjusting member 31 and the friction member 32, which reduces the hard collision when the two are in direct contact, effectively preventing the occurrence of the sticking phenomenon, thereby improving the smoothness of the adjustment process and allowing users to adjust the steering damping more easily. On the other hand, when the friction member 32 contacts the head pipe assembly 10, the buffering effect of the elastic member 33 reduces the wear of the friction surface and avoids the damage caused by hard contact, thereby significantly improving the service life of the friction member 32 and the head pipe assembly 10, reducing maintenance costs, and improving the durability of the entire steering device.

[0074] In some embodiments, the elastic member 33 includes any one of a wave washer, a spring, and a rubber ring. In this way, the characteristics of different types of elastic members 33 (such as wave washers, springs, and rubber rings) can be utilized to provide diverse damping adjustment methods to suit different user preferences and different vehicle structural requirements.

[0075] In some embodiments, as Figure 3 As shown, a mounting groove 311 is provided on one side of the adjustment member 31 facing the head pipe assembly 10 . Along the axial direction L, one end of the friction member 32 is mounted in the mounting groove 311 , and the other end of the friction member 32 protrudes from or is flush with the adjustment member 31 .

[0076] In the above technical solution, the friction member 32 can be installed by setting the installation groove 311. At the same time, the protruding or flush design of the friction member 32 can achieve effective contact with the head pipe assembly 10, so that friction can be generated between the friction member 32 and the head pipe assembly 10.

[0077] In some embodiments, as Figure 3 and Figure 4 As shown, an escape groove 312 is provided on the side of the adjustment member 31 facing away from the head pipe assembly 10 along the axial direction L. This allows for an escape groove at the connection point between the front fork 40 and the steering assembly 20. This not only prevents the connection point from interfering with the rotation of the adjustment member 31, thereby ensuring a smooth adjustment process, but also maintains the aesthetics of the steering device.

[0078] In some embodiments, as Figure 2 and Figure 3 As shown, the steering device also includes a front fork 40, which is welded to the outer periphery of the steering assembly 20. The avoidance groove 312 is used to accommodate the weld 50 between the front fork 40 and the steering assembly 20. The provision of the avoidance groove 312 ensures that the adjustment member 31 does not interfere with the weld 50 during rotation, thereby ensuring smoother steering damping adjustment. Furthermore, the presence of the weld 50 within the avoidance groove 312 also enhances the overall aesthetics of the steering device.

[0079] In some embodiments, as Figure 4 As shown, a mounting through hole 321 is provided on the friction member 32, and at least one first stop-rotation portion 322 is provided on the inner wall of the mounting through hole 321. At least one second stop-rotation portion 21 is provided on the outer periphery of the steering assembly 20. At least one first stop-rotation portion 322 is arranged in a one-to-one correspondence with at least one second stop-rotation portion 21, and the mounting through hole 321 is prevented from rotating by the first stop-rotation portion 322 and the second stop-rotation portion 21.

[0080] In the above technical solution, the cooperation between the first anti-rotation portion 322 and the second anti-rotation portion 21 can prevent relative rotation between the friction member 32 and the steering assembly 20. In this way, when the steering assembly 20 rotates relative to the head pipe assembly 10, the friction member 32 can be rotated relative to the head pipe assembly 10, thereby generating friction damping between the friction member 32 and the head pipe assembly 10.

[0081] In some embodiments, as Figure 4 As shown, there are two first anti-rotation parts 322 and two second anti-rotation parts 21 , and the two first anti-rotation parts 322 correspond to the two second anti-rotation parts 21 .

[0082] Of course, in another embodiment not shown in the figure, the first stop part 322 can also be one, and the second stop part 21 can also be one; or, the first stop part 322 can also be three, four, five, etc., and the second stop part 21 can also be three, four, five, etc.

[0083] In some embodiments, as Figure 4As shown, the first anti-rotation portion 322 is an anti-rotation plane, and the second anti-rotation portion 21 is an anti-rotation plane. In this way, through the cooperation between the anti-rotation planes, the friction member 32 and the steering assembly 20 can be prevented from rotating, so that friction damping is generated between the friction member 32 and the head pipe assembly 10.

[0084] Of course, in another embodiment (not shown), the first anti-rotation portion 322 is a protrusion and the second anti-rotation portion 21 is a groove; or the first anti-rotation portion 322 is a groove and the second anti-rotation portion 21 is a protrusion. In this way, the engagement between the protrusion and the groove can prevent rotation between the friction member 32 and the steering assembly 20, thereby generating frictional damping between the friction member 32 and the head pipe assembly 10.

[0085] The inventors are aware of a steering device that generally achieves steering damping adjustment by connecting an external steering damper. This will cause the damper to protrude from the head tube assembly 10, thereby affecting the aesthetics. Therefore, in some embodiments, such as Figure 2 As shown, the steering assembly 20 includes a rotating tube 22 and a folding seat 60 connected to the rotating tube 22, the steering device also includes a front fork 40 installed on the outer periphery of the rotating tube 22, and the head tube assembly 10 is located between the folding seat 60 and the front fork 40; a damping assembly 30 is provided between the head tube assembly 10 and the front fork 40; and / or, a damping assembly 30 is provided between the head tube assembly 10 and the folding seat 60; wherein, the head tube assembly 10 includes a head tube 11 and a bowl group 12, and the end of the head tube 11 is provided with the bowl group 12, and the friction member 32 can abut against at least one of the head tube 11 and the bowl group 12.

[0086] In the above technical solution, by integrating the damping assembly 30 into the structure of the steering device, that is, arranging the damping assembly 30 between the head tube assembly 10 and the front fork 40, and / or arranging the damping assembly 30 between the head tube assembly 10 and the folding seat 60, the aesthetic problem caused by the external steering damper can be solved, so as to avoid the damper being exposed and affecting the neatness of the vehicle appearance.

[0087] In some embodiments, as Figure 3 As shown, the outer wall of the adjusting member 31 is flush with the outer wall of the head pipe 11 to avoid affecting the appearance due to the protrusion of the damping assembly 30.

[0088] In some embodiments, as Figure 2As shown, along the axial direction L, both ends of the head tube 11 are provided with a headset 12, and the rotating tube 22 is rotatably arranged in the head tube 11 through the two headsets 12; wherein, when the damping assembly 30 is provided between the head tube assembly 10 and the front fork 40, the friction member 32 can abut against the headset 12 located on the side of the head tube 11 facing the front fork 40; when the damping assembly 30 is provided between the head tube assembly 10 and the folding seat 60, the friction member 32 can abut against the headset 12 located on the side of the head tube 11 facing the folding seat 60.

[0089] In the above technical solution, by arranging the bowl assembly 12 at both ends of the head pipe 11, the stable rotation of the steering assembly 20 in the head pipe can be ensured. At the same time, the setting position of the damping assembly 30 can be adjusted according to actual needs, thereby improving the flexibility of steering damping adjustment.

[0090] In some embodiments, as Figure 3 As shown, the steering assembly 20 includes a rotating tube 22 and a mounting tube 23 connected to the rotating tube 22, the damping assembly 30 is mounted on the outer periphery of the mounting tube 23, and the adjusting member 31 is movably disposed on the outer periphery of the mounting tube 23. This facilitates processing.

[0091] In some embodiments, as Figure 3 As shown, the adjusting member 31 is threadedly engaged with the mounting cylinder 23 .

[0092] In some embodiments, as Figure 3 As shown, the headset 12 located on the side of the head pipe 11 facing the front fork 40 is located on the outer periphery of the mounting tube 23 .

[0093] In some embodiments, as Figure 3 As shown, the friction member 32 is movably sleeved on the outer periphery of the mounting cylinder 23 , and the elastic member 33 is located on the outer periphery of the mounting cylinder 23 .

[0094] In some embodiments, the rotating tube 22 and the mounting tube 23 are integrally formed, thereby reducing the number of assembly steps and facilitating assembly.

[0095] Of course, in another embodiment not shown in the figures, the rotating tube 22 and the mounting cylinder 23 may also be provided separately.

[0096] The present invention has at least the following beneficial effects: the adjustment member and the friction member in the damping assembly work together, and by moving the adjustment member along the axial direction L, the friction member can be brought into contact with the head pipe assembly and generate friction, thereby providing a damping effect for the steering operation of the steering assembly, and by moving the adjustment member closer to or farther away from the head pipe assembly along the axial direction L, the contact degree and contact pressure between the friction member and the head pipe assembly can be adjusted. In this way, compared with the damping adjustment structure in the prior art that uses fixed friction based on damping oil and adopts multiple wedge blocks and screws, in the present application, the contact pressure of the friction member is directly changed by using the movement of the adjustment member, which not only can adjust the friction between the friction member and the head pipe assembly in real time according to actual riding conditions, thereby improving the vehicle's handling and stability, but also reduces the number of parts and simplifies the linkage structure, thereby achieving simplification in the damping adjustment structure, reducing assembly difficulty, and reducing production costs.

[0097] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and all variations coming within the meaning and range of equivalents of the claims are intended to be included therein.
