Description

Technical Field

[0001] This utility model relates to the technical field of transportation vehicles, specifically to a front fork assembly and a scooter. Background Technology

[0002] Electric scooters, with their convenience and flexibility, play a vital role in short-distance urban commuting. As a key component of electric scooters, the front fork assembly connects the handlebars, steering system, and front wheel, directly impacting riding safety and comfort. Currently, most electric scooters on the market use a traditional internal thread locking structure to secure the front fork assembly. This involves machining internal threads inside the lower end of the front fork steerer tube, then using a long screw to pass through the lower seat from bottom to top and screw into the internal threads of the steerer tube, thus achieving a tight fit.

[0003] However, this traditional design has significant limitations. First, because the interior of the riser needs to reserve space for machining internal threads, this encroaches on the already limited internal space, making it difficult for brake cables, power cables, and other wiring to pass through smoothly. This increases the risk of wiring harness jamming and wear, thus affecting overall reliability and safety. Second, to ensure the robustness of the internal thread structure, the riser wall cannot be too thin. This means either using thicker materials, increasing product cost and weight, or reducing the strength of this area, creating a potential hazard that could affect the vehicle's lifespan and rider safety.

[0004] As a result, the front fork components of existing scooters suffer from poor reliability and weak connection strength. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a front fork assembly and a scooter.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] One aspect of this application provides a front fork assembly, including a folding seat, a front fork steerer tube, and a mating component. The folding seat has a channel structure through which the front fork steerer tube passes. A first end of the front fork steerer tube is located on the outer side of the channel structure. The mating component is located on the outer circumferential surface of the first end of the front fork steerer tube. Along the axial direction of the front fork steerer tube, the mating component abuts against the folding seat and is used to lock the front fork steerer tube to the folding seat. This application, by providing a mating component at the first end of the front fork steerer tube and utilizing its interaction with the folding seat, achieves a stable connection between the front fork steerer tube and the folding seat, ensuring the stability of the front fork steerer tube during use. This effectively solves the problems of difficult wiring and insufficient structural strength in traditional internal thread structures, improving the reliability and safety of the scooter.

[0008] In some embodiments, a groove is provided on one of the inner circumferential surface of the mating component and the outer circumferential surface of the first end of the fork steerer tube, and a protrusion is provided on the other, with at least a portion of the protrusion disposed inside the groove; or the mating component and the fork steerer tube are connected by fasteners; or the mating component and the fork steerer tube are connected by a threaded rotation. This application provides a variety of connection methods to ensure a firm connection between the mating component and the fork steerer tube. The use of grooves and protrusions utilizes the mechanical engagement principle, the fastener connection utilizes the mechanical locking principle, and the threaded connection utilizes the threaded locking principle. Through the application of these principles, the stability and reliability of the connection are achieved, which not only improves the stability of the connection but also simplifies the assembly process and reduces manufacturing costs.

[0009] In some embodiments, the outer circumferential surface of the first end of the fork steerer tube has an external thread, and the inner circumferential surface of the mating component has an internal thread. The first end of the fork steerer tube and the mating component are rotatably connected via the internal and external threads. This application utilizes the engagement of the external and internal threads to achieve quick locking and disengagement between the fork steerer tube and the mating component. The threaded connection utilizes the self-locking characteristic of the thread. By rotating the mating component, it is made to tightly engage with the external thread of the first end of the fork steerer tube, thereby achieving locking. This not only improves assembly efficiency but also ensures the reliability of the connection and reduces wear on the wiring harness.

[0010] In some embodiments, the fork assembly further includes a spacer sleeved on the fork steerer tube and abutting between the folding seat and the mating component. This application improves the stability and reliability of the connection by providing a spacer between the folding seat and the mating component, utilizing the spacer's cushioning and positioning functions. The spacer utilizes the cushioning properties of the material, and through contact between the spacer and the folding seat and the mating component, it reduces connection loosening caused by vibration, while providing better positioning. This not only improves connection stability but also reduces direct wear between the folding seat and the mating component, extending the scooter's service life.

[0011] In some embodiments, along the axial direction of the fork steerer tube, the fork steerer tube includes a first section and a second section connected together. At least a portion of the first section is disposed on the outside of the channel structure to form a first end of the fork steerer tube, and at least a portion of the second section is disposed inside the channel structure. The wall thickness of the first section is less than the wall thickness of the second section. This application designs the fork steerer tube as a first section and a second section, where the first section is used to connect with the folding seat, and the second section is used to ensure structural strength. The thin-walled design of the first section utilizes the principle of material stress distribution, reducing the weight of the fork assembly by reducing material in non-stressed areas, while the thick-walled design of the second section ensures the structural strength of the stress-bearing areas. This design not only reduces the weight of the fork assembly but also ensures its stability and safety during use.

[0012] In some embodiments, the folding seat includes a first seat and a second seat that are rotatably connected. The first seat has a channel structure, and the fork steerer is locked to the first seat via a mating member. The folding seat has a folded position and an unfolded position. When the folding seat is in the unfolded position, an installation area is formed between the first seat and the second seat, and the first end of the fork steerer and the mating member are disposed inside the installation area. This application, by designing the folding seat as a first seat and a second seat, realizes the folding function of the fork assembly by utilizing their relative rotation. The folding and unfolding of the folding seat are realized by utilizing the rotatable connection between the first seat and the second seat. The first seat and the second seat cooperate to accommodate the mating member, realizing the stability of the connection between the mating member, the fork steerer, and the folding seat. The structural design of this application improves the portability and safety of the scooter.

[0013] In some embodiments, a first groove structure is provided at one end of the first seat body connected to the second seat body, and the inner cavity of the first groove structure forms an installation area; or a second groove structure is provided at one end of the second seat body connected to the first seat body, and the inner cavity of the second groove structure forms an installation area; or a first groove structure is provided at one end of the first seat body connected to the second seat body, and a second groove structure is provided at one end of the second seat body connected to the first seat body, with the first groove structure and the second groove structure communicating and cooperating to form an installation area. This application, by providing groove structures on the first seat body and / or the second seat body, provides sufficient installation space for the first end of the fork steerer tube and the mating parts, avoiding difficulties in wiring harness routing. The use of groove structures not only simplifies the assembly process but also improves the smoothness of wiring harness routing, reduces wiring harness wear, and ensures the structural strength of the folding seat.

[0014] In some embodiments, the fork assembly further includes a fork riser, which is disposed on the second seat. When the folding seat is in the unfolded position, the axis of the fork riser is collinear or parallel to the axis of the fork steerer. This application achieves a stable connection between the fork steerer, the fork riser, and the folding seat by providing a fork riser. By ensuring that the axis of the fork riser is collinear or parallel to the axis of the fork steerer, the stability of the fork assembly during use is ensured. This design not only improves the riding stability of the scooter but also simplifies the assembly process of the fork assembly and reduces manufacturing costs.

[0015] In some embodiments, the second seat includes a connecting tube along the axial direction of the fork stem. The connecting tube includes a first portion and a second portion connected together. The first portion is disposed inside and connected to the fork stem, and the second portion is disposed outside the fork stem. The outer diameter of the second portion is larger than the outer diameter of the first portion. One end of the second portion connected to the first portion forms an annular support surface, and the end face of the fork stem abuts against the support surface. The second seat of this application includes a connecting tube, wherein the first portion of the connecting tube is connected to the fork stem, and the second portion provides a support surface. The support surface utilizes the contact surface support principle. By increasing the contact area, the contact between the end face of the fork stem and the support surface ensures the stability of the fork assembly, simplifies the structure of the fork assembly, and reduces manufacturing costs.

[0016] Another aspect of this application provides a scooter that includes the aforementioned front fork assembly. The scooter of this application, employing the aforementioned front fork assembly, utilizes the cooperative structure of the front fork riser, mating parts, and folding seat to improve the reliability and safety of the scooter.

[0017] This utility model has the following beneficial effects:

[0018] This application achieves a stable connection between the front fork steerer tube and the folding seat by setting a mating part at the first end of the front fork steerer tube and utilizing its interaction with the folding seat. This ensures the stability of the front fork steerer tube during use, effectively solves the problems of difficult wiring and insufficient structural strength in traditional internal thread structures, and improves the reliability and safety of the scooter.

[0033] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0034] To address the issues of poor reliability and weak connection strength in the front fork assembly of existing scooters, this invention provides a scooter.

[0035] Among them, the scooter is an electric scooter.

[0036] Specifically, the scooter is an electric folding scooter.

[0037] In this embodiment, the scooter includes a front fork assembly, which is configured as a foldable structure. This allows the scooter to be transported or stored in a way that reduces its space requirements, thereby improving efficiency and structural stability.

[0038] like Figures 1 to 4 As shown, the fork assembly includes a folding seat 10, a fork steer 20, and a mating member 30. The folding seat 10 has a channel structure through which the fork steer 20 passes. The first end of the fork steer 20 is located on the outside of the channel structure. The mating member 30 is located at the first end of the fork steer 20. Along the axial direction of the fork steer 20, the mating member 30 abuts against the folding seat 10 and is used to lock the fork steer 20 to the folding seat 10.

[0039] The length of the fork steerer tube 20 is greater than the length of the channel structure, so that the first end of the fork steerer tube 20 extends through the channel structure and connects with the mating part 30.

[0040] This application achieves a stable connection between the front fork steerer tube 20 and the folding seat 10 by setting a mating part 30 at the first end of the front fork steerer tube 20 and utilizing its interaction with the folding seat 10. This ensures the stability of the front fork steerer tube 20 during use, effectively solves the problems of difficult wiring and insufficient structural strength in traditional internal thread structures, and improves the reliability and safety of the scooter.

[0041] Specifically, the mating part 30 is disposed on the outer peripheral surface of the first end of the front fork steer tube 20, and the end of the mating part 30 abuts against the outer peripheral edge of the channel structure opening end on the folding seat 10 to achieve the positioning of the mating part 30.

[0042] In this embodiment, the mating component 30 is detachably mounted on the fork steerer tube 20 to facilitate the installation and removal of the fork steerer tube 20, the mating component 30, and the folding seat 10. This detachable design makes the replacement and maintenance of the mating component 30 more convenient. The detachable design not only facilitates wiring harness routing but also improves the scooter's maintenance convenience and reduces maintenance costs.

[0043] like Figure 4 As shown, along the axial direction of the fork steer tube 20, the fork steer tube 20 includes a first section 210 and a second section 220 connected together. At least a portion of the first section 210 is disposed on the outside of the channel structure to form the first end of the fork steer tube 20, and at least a portion of the second section 220 is disposed inside the channel structure. The wall thickness of the first section 210 is less than the wall thickness of the second section 220.

[0044] In terms of the direction of force, the first section 210 is only used for vertical suspension, while the second section 220 serves as the load-bearing component for front and rear forces. In this application, the wall thickness of the second section 220 is greater than that of the first section 210, thereby ensuring the connection of the fork steer tube 20 while ensuring structural strength and thus achieving a stable connection between the fork steer tube 20 and the mating component 30.

[0045] Specifically, a corresponding external thread can be provided on the outer circumferential surface of the first segment 210. The external thread is used to connect with the mating part 30. By providing an external thread at the first segment 210, the wall thickness of the first segment 210 is made smaller than the wall thickness of the second segment 220.

[0046] This application designs the fork steerer tube 20 as a first section 210 and a second section 220. The first section 210 is used to connect with the folding seat 10, and the second section 220 is used to ensure structural strength. The thin-walled design of the first section 210 utilizes the principle of material stress distribution. By reducing the material in non-stressed areas, the weight of the fork assembly is reduced. The thick-walled design of the second section 220 ensures the structural strength of the stress-bearing areas. This design not only reduces the weight of the fork assembly but also ensures its stability and safety during use.

[0047] In this embodiment, there are multiple ways to detachably connect the mating part 30 and the fork steer tube 20.

[0048] In one specific embodiment not shown, a groove is provided on one of the inner peripheral surface of the mating part 30 and the outer peripheral surface of the first end of the fork steer 20, and a protrusion is provided on the other, with at least a portion of the protrusion disposed inside the groove.

[0049] The slot is located on the inner peripheral wall of the mating part 30 or on the raised outer peripheral wall.

[0050] Specifically, the slot and the protrusion form a snap-fit ​​structure. The slot can be set on the mating part 30 or on the fork steer tube 20. After the mating part 30 is installed on the fork steer tube 20, at least a part of the protrusion extends into the inside of the slot, so that the mating part 30 and the fork steer tube 20 are snap-fitted by the protrusion and the slot.

[0051] In one specific embodiment not shown, the mating part 30 is connected to the fork steerer tube 20 by fasteners.

[0052] Specifically, the fastener can be a structural component such as a bolt. After the mating part 30 is set on the front fork steer tube 20, it can be connected to the front fork steer tube 20 by the fastener passing through the fastener radially along the front fork steer tube 20, thereby realizing the connection and fixation between the mating part 30 and the front fork steer tube 20.

[0053] like Figure 4 In the specific embodiment shown, the mating part 30 and the fork steerable tube 20 are connected by a threaded rotation.

[0054] Specifically, the outer circumferential surface of the first end of the fork steer 20 has an external thread, and the inner circumferential surface of the mating part 30 has an internal thread. The first end of the fork steer 20 and the mating part 30 are rotatably connected through the internal and external threads.

[0055] This application utilizes the combination of external and internal threads to achieve quick locking and disassembly between the front fork steer tube 20 and the mating part 30. The threaded connection utilizes the self-locking characteristic of the thread. By rotating the mating part 30, it is made to tightly engage with the external thread at the first end of the front fork steer tube 20, thereby achieving locking. This not only improves assembly efficiency but also ensures the reliability of the connection and reduces the wear of the wiring harness.

[0056] Among them, the mating part 30 can be a sleeve or a nut. This application uses a sleeve or nut as the mating part 30 and uses them to engage with the external thread of the front fork steer 20 to achieve the locking function. The selection of sleeve or nut not only simplifies the assembly process, but also reduces the manufacturing cost and improves the reliability and safety of the scooter.

[0057] In this embodiment, the present application provides multiple connection methods to ensure a secure connection between the mating part 30 and the fork steerer tube 20. The use of a slot and protrusion utilizes a mechanical engagement principle, the fastener connection utilizes a mechanical locking principle, and the threaded connection utilizes a threaded locking principle. Through the application of these principles, the stability and reliability of the connection are achieved, which not only improves the stability of the connection but also simplifies the assembly process and reduces manufacturing costs.

[0058] In this embodiment, the fork assembly also includes a gasket, which is sleeved on the fork steer tube 20 and abuts against the folding seat 10 and the mating member 30 along the axial direction of the fork steer tube 20.

[0059] The gasket is made of cushioning material and is formed into a ring shape.

[0060] This application improves the stability and reliability of the connection by setting a shim between the folding seat 10 and the mating part 30, utilizing the cushioning and positioning function of the shim. The shim utilizes the cushioning characteristics of the material, and the contact between the shim and the folding seat 10 and the mating part 30 reduces the loosening of the connection caused by vibration, while providing a better positioning effect. This not only improves the stability of the connection, but also reduces the direct wear between the folding seat 10 and the mating part 30, extending the service life of the fork assembly.

[0061] like Figure 4 As shown, the folding seat 10 includes a first seat body 110 and a second seat body 120 rotatably connected. The first seat body 110 has a channel structure, and the fork steerer tube 20 is locked onto the first seat body 110 by a fitting 30. The folding seat 10 has a folded position and an unfolded position. When the folding seat 10 is in the unfolded position, an installation area is formed between the first seat body 110 and the second seat body 120, and the first end of the fork steerer tube 20 and the fitting 30 are disposed inside the installation area.

[0062] In this application, the folding seat 10 is designed as a first seat body 110 and a second seat body 120. The folding function of the fork assembly is realized by their relative rotation. The folding and unfolding of the folding seat 10 is realized by the rotational connection of the first seat body 110 and the second seat body 120. The state of the folding seat 10 can be switched according to the usage scenario. It is convenient to operate and easy to use, which helps to improve the user experience.

[0063] Specifically, by accommodating the first seat 110 and the second seat 120 with the mating part 30, the stability of the connection between the mating part 30, the front fork steer 20 and the folding seat 10 is achieved. The structural design of this application improves the portability and safety of the scooter.

[0064] In this embodiment, when the folding seat 10 is in the unfolded position, the first seat body 110 and the second seat body 120 cooperate to hide the mating part 30 and the first end of the fork steer tube 20 inside the installation area, thereby achieving protection of the connection area between the mating part 30 and the fork steer tube 20, which is beneficial to strengthening the stability of the structure. When it is necessary to disassemble the mating part 30, the folding seat 10 can be switched to the folding position to expose the mating part 30. By operating the mating part 30, the mating part 30 can be separated from the fork steer tube 20.

[0065] like Figure 4 As shown, the installation area is formed between the first base 110 and the second base 120.

[0066] Specifically, the first base 110 may have a first groove structure with its opening facing the second base 120 at one end where it connects to the second base 120. The inner cavity of the first groove structure forms an installation area, and the second base 120 blocks the opening of the first groove structure.

[0067] Specifically, the second base 120 may have a second groove structure with its opening facing the first base 110 at one end where it is connected to the first base 110. The inner cavity of the second groove structure forms an installation area, and the first base 110 blocks the opening of the second groove structure.

[0068] Specifically, the first base 110 may be provided with a first groove structure with its opening facing the second base 120 at one end, and the second base 120 may be provided with a second groove structure with its opening facing the first base 110 at one end, with the first groove structure and the second groove structure communicating and cooperating to form an installation area.

[0069] This application utilizes a slot structure to provide sufficient installation space for the first end of the fork steerer tube 20 and the mating part 30 by setting a slot structure on the first seat 110 and / or the second seat 120. This avoids difficulties in wiring harness routing. The use of the slot structure not only simplifies the assembly process but also improves the smoothness of wiring harness routing, reduces wiring harness wear, and ensures the structural strength of the folding seat 10.

[0070] like Figures 1 to 4 As shown, the fork assembly also includes a fork riser 40, which is mounted on the second seat 120. When the folding seat 10 is in the unfolded position, the axis of the fork riser 40 is collinear or parallel to the axis of the fork steer 20.

[0071] The fork riser 40 is mounted on the second seat 120 and moves with the second seat 120, while the fork steer 20 is mounted on the first seat 110 and moves with the first seat 110, thereby enabling the folding and unfolding of the fork steer 20 and the fork riser 40.

[0072] This application achieves a stable connection between the front fork riser 40, the front fork vertical tube 20, and the folding seat 10 by setting the front fork riser 40. By making the axis of the front fork riser 40 collinear or parallel with the axis of the front fork vertical tube 20, the stability of the front fork assembly during use is ensured. This design not only improves the riding stability of the scooter, but also simplifies the assembly process of the front fork assembly and reduces manufacturing costs.

[0073] Specifically, the second seat 120 includes a connecting pipe 121 along the axial direction of the fork riser 40. The connecting pipe 121 includes a first part 1211 and a second part 1212 connected together. The first part 1211 is disposed inside the fork riser 40 and connected to the fork riser 40. The second part 1212 is disposed outside the fork riser 40. The outer diameter of the second part 1212 is larger than the outer diameter of the first part 1211. One end of the second part 1212 connected to the first part 1211 forms an annular support surface 1213. The end face of the fork riser 40 abuts against the support surface 1213.

[0074] The first part 1211 and the second part 1212 of the connecting tube 121 are integrated into a single structure. The first part 1211 is hidden inside the fork riser 40 to form an internal connection. Specifically, the connection can be made by fasteners such as bolts or by welding. The second part 1212 is located outside the fork riser 40 to form a stop and limit for the fork steer 20, so as to ensure the accuracy and stability of the connection between the fork steer 20 and the second seat 120.

[0075] This application includes a connecting tube 121 in the second seat 120, wherein the first part 1211 of the connecting tube 121 is connected to the fork riser 40, and the second part 1212 provides a support surface 1213. The support surface 1213 is designed using the contact surface support principle, employing an annular support surface to increase the contact area and ensure uniform stress distribution in the contact area. The contact between the end face of the fork riser 40 and the support surface 1213 ensures the stability of the fork assembly, simplifies the structure of the fork assembly, and reduces manufacturing costs.

[0076] In operation, the first end of the front fork steerer tube 20 is locked to the folding seat 10 via the mating part 30, ensuring the stability of the scooter during travel. During use, the folding and unfolding operation of the folding seat 10 is simple; the folding and unfolding of the front fork assembly is achieved through the relative rotation of the first seat body 110 and the second seat body 120, facilitating carrying and storage. Simultaneously, the cooperation between the front fork steerer tube 40 and the connecting tube 121 ensures stable support for the front fork assembly, improving the scooter's stability and safety. Through the implementation of the above technical solution, the scooter achieves lightweight and flexible characteristics while maintaining structural strength, improving the user experience.

[0077] This utility model has the following beneficial effects:

[0078] This application achieves a stable connection between the front fork steerer tube 20 and the folding seat 10 by setting a mating part 30 at the first end of the front fork steerer tube 20 and utilizing its interaction with the folding seat 10.
