Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and more specifically, to a steering unit, a handlebar assembly, and a scooter. Background Technology

[0002] In existing technology, turn signals include a lamp housing and an end cap. The end cap is generally fixed to the handlebar tube with screws, and then the lamp housing is pressed against the handlebar tube using the end cap. During the assembly of the end cap, the lamp housing and the end cap need to be put onto the handlebar tube one by one. After adjusting the angle of the lamp housing, the installer needs to press the lamp housing and the end cap firmly with one hand and install the screw with the other hand. Alternatively, the lamp housing can be directly installed on the handlebar tube using screws, and then the end cap can be fixed to the handlebar tube using screws. Whether the end cap is used to press the lamp housing against the end cap or the end cap and lamp housing are installed separately with screws, the assembly process is prone to being cumbersome and inconvenient, and it is also easy to lose parts. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a steering unit, a handlebar assembly, and a scooter.

[0004] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0005] A steering unit includes: a light-emitting component comprising a base and a light-emitting element disposed on the base, the base being configured to be detachably mounted on the handlebar tube; and an end cap component located at the outer end of the base, the end cap component being threadedly connected to the base. In this technical solution, the end cap component can be threadedly connected to the base to form the steering unit, and then the entire steering unit can be mounted on the base. This avoids the need for separate assembly of the light-emitting component and the end cap component, and eliminates the need to manually press the light-emitting component onto the handlebar tube during assembly. This reduces assembly difficulty and the probability of losing parts during assembly, thereby solving the problems of cumbersome assembly steps, inconvenience, and the likelihood of losing parts in steering unit assembly.

[0006] In some embodiments, the end cap component is a cylindrical structure with one open end and one closed end. The base includes a mounting cylinder and a connecting cylinder connected to the mounting cylinder. The mounting cylinder and the connecting cylinder are sleeved on the end of the horizontal tube. A light-emitting element is provided on the mounting cylinder, and the end cap component is threadedly connected to the outer periphery of the connecting cylinder. In the above technical solution, the threaded connection between the outer periphery of the connecting cylinder and the end cap component can not only effectively disperse external forces to reduce damage to the light-emitting element, but also achieve a firm connection and convenient disassembly between components.

[0007] In some embodiments, the outer diameter of the mounting cylinder is larger than the outer diameter of the connecting cylinder, and a stepped surface is provided between the connecting cylinder and the mounting cylinder to axially limit the end cap component. This design ensures that the end cap component is difficult to move excessively axially in the assembled state, thereby preventing damage to the end cap component.

[0008] In some embodiments, the steering unit further includes a buffer located on the outer periphery of the connecting cylinder, and the buffer is located between the end cap member and the stepped surface. In the above technical solution, the elastic deformation of the buffer can efficiently absorb and mitigate the instantaneous impact force caused by unexpected events such as vehicle side falls or collisions, effectively preventing the impact energy from being directly transferred to the light source and other key electronic components, thereby reducing the probability of device damage and functional failure caused by external forces, and thus reducing maintenance costs.

[0009] In some embodiments, a mounting portion is provided on the outer periphery of the base, and the light-emitting element is mounted on the base through the mounting portion. In this way, the light-emitting element can be mounted on the base.

[0010] In some embodiments, the mounting part is a mounting groove, and the light-emitting element is mounted in the mounting groove. The bottom wall of the mounting groove is provided with a wire-passing hole that communicates with the inside of the horizontal tube. In the above technical solution, the wire-passing hole can ensure the connection between the light-emitting element and the internal circuit, reduce the corrosion and wear of the wires by the external environment, and at the same time, the design of the mounting groove makes the installation process of the light-emitting element simpler, and can achieve fast and accurate assembly without complicated positioning tools, which greatly improves production efficiency.

[0011] In some embodiments, the light-emitting element is interference-fitted or snap-fitted into the mounting groove. This allows the light-emitting element to be directly pressed into the mounting groove, facilitating assembly.

[0012] In some embodiments, the mounting groove extends to the inner end of the base away from the end cap member, and the light-emitting element is slidably disposed in the mounting groove. Thus, by aligning the light-emitting element with the mounting groove and pushing it, the light-emitting element can be installed within the mounting groove, thereby improving the ease of installation.

[0013] In some embodiments, a limiting groove is provided on one of the inner wall of the mounting groove and the light-emitting element, and a limiting part is provided on the other of the inner wall of the mounting groove and the light-emitting element. The limiting groove and the limiting part are matched to limit the light-emitting element to prevent it from falling off. In the above technical solution, by providing a limiting groove and a limiting part that match to limit the light-emitting element, it is possible to prevent the light-emitting element from falling radially off the base due to vibration during vehicle operation, thus ensuring the continuous and reliable operation of the lighting system.

[0014] A handlebar assembly includes: a handlebar; and the aforementioned steering unit, which is mounted on the end of the handlebar.

[0015] In some embodiments, the handlebar has an anti-rotation groove that communicates with and extends to one end of the handlebar. A base is fitted around the outer periphery of the handlebar, and an anti-rotation member is provided inside the base, which slides into the anti-rotation groove. In this technical solution, the base can be fitted around the outer periphery of the handlebar during assembly. The anti-rotation member and the anti-rotation groove on the handlebar slide together. The anti-rotation groove provides positioning and anti-rotation functions for the base, ensuring its alignment and stable installation on the handlebar. This avoids loosening and misalignment caused by mechanical vibration or torsional forces, enhancing the mechanical reliability and service life of the entire steering unit. Furthermore, the combined use of the anti-rotation groove and the anti-rotation member simplifies assembly steps, allowing for quick installation and disassembly of the base without additional tools or complex procedures, significantly improving production efficiency and maintenance convenience.

[0016] In some embodiments, the anti-rotation component includes an anti-rotation element and an anti-detachment element connected to the anti-rotation element. The cross-sectional area of ​​the anti-detachment element is larger than that of the anti-rotation element. The anti-rotation element slides in conjunction with the anti-rotation groove, and the anti-detachment element is located inside the handlebar tube. In the above technical solution, the anti-rotation element can ensure the axial translational stability of the base and effectively suppress the rotational movement of the steering unit. At the same time, the internal positioning function of the anti-detachment element prevents the anti-rotation component from dislodging from the anti-rotation groove when subjected to load or impact, thereby enhancing the safety and durability of the steering unit and reducing maintenance frequency and cost.

[0017] In some embodiments, the handlebar assembly further includes a locking member that passes through the base and connects to the handlebar. The locking member and the anti-rotation member are spaced apart circumferentially along the handlebar. In the above technical solution, on the one hand, the radial locking effect of the locking member enhances the physical connection strength between the base and the handlebar, ensuring the steering unit remains stable even under high-intensity vibration or impact conditions, thereby reducing signal distortion and functional failures caused by loose connections; on the other hand, the synergistic effect of the anti-rotation member and the locking member further improves the system's anti-rotation performance.

[0018] A scooter includes a frame and the aforementioned handlebar assembly, wherein the handlebar assembly is disposed on the frame.

[0019] This utility model has the following advantages: the end cap component can be threadedly connected to the base to form a steering unit, and then the steering unit can be installed on the base as a whole. This avoids the situation of assembling the light-emitting component and the end cap component separately, and also eliminates the need to manually press the light-emitting component onto the handlebar during assembly. This reduces the assembly difficulty and the probability of losing parts during assembly, thereby solving the problems of complicated assembly steps, inconvenient assembly, and easy loss of parts in the steering unit assembly.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0037] To address the problems of cumbersome assembly steps, inconvenience, and easy loss of parts in the existing turn signal assembly process, this utility model provides a steering unit, a handlebar assembly, and a scooter.

[0038] In some embodiments, the scooter includes a frame and a handlebar assembly, with the handlebar assembly disposed on the frame.

[0039] In some embodiments, such as Figures 1 to 6 As shown, the cross tube assembly includes a cross tube 71 and a steering unit, the steering unit being mounted at the end of the cross tube 71.

[0040] The steering unit, the cross tube assembly, and the scooter will be explained in detail below.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the handle tube 71 is provided with an anti-rotation groove 72, which is connected to the interior of the handle tube 71 and extends to one end of the handle tube 71. The base 10 is sleeved on the outer periphery of the handle tube 71, and the base 10 is provided with an anti-rotation member 13 inside the base 10. The anti-rotation member 13 is slidably engaged with the anti-rotation groove 72.

[0042] In the above technical solution, the base 10 can be fitted onto the outer periphery of the handlebar tube 71 during assembly. The anti-rotation component 13 and the anti-rotation groove 72 on the handlebar tube 71 form a sliding pair. The anti-rotation groove 72 provides positioning and anti-rotation functions for the base 10, which can ensure the alignment and stable installation of the base 10 on the handlebar tube 71, avoid loosening and misalignment caused by mechanical vibration or torsional force, and enhance the mechanical reliability and service life of the entire steering unit. At the same time, the combined use of the anti-rotation groove 72 and the anti-rotation component 13 simplifies the assembly steps, and the base 10 can be quickly installed and disassembled without additional tools or complicated steps, which significantly improves production efficiency and maintenance convenience.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the anti-rotation component 13 includes an anti-rotation member 131 and an anti-detachment member 132 connected to the anti-rotation member 131. The cross-sectional area of ​​the anti-detachment member 132 is larger than the cross-sectional area of ​​the anti-rotation member 131. The anti-rotation member 131 is slidably engaged with the anti-rotation groove 72. The anti-detachment member 132 is located inside the handle tube 71.

[0044] In the above technical solution, the anti-rotation component 131 can ensure the translational stability of the base 10 along the axial direction and effectively suppress the rotational movement of the steering unit; at the same time, the internal positioning function of the anti-detachment component 132 prevents the anti-rotation component 13 from detaching from the anti-rotation groove 72 when subjected to load or encountering impact, thereby enhancing the safety and durability of the steering unit and reducing maintenance frequency and cost.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the handlebar assembly also includes a locking member 73, which passes through the base 10 and is connected to the handlebar 71. The locking member 73 and the anti-rotation member 13 are spaced apart along the circumference of the handlebar 71.

[0046] In the above technical solution, on the one hand, the radial locking effect of the locking member 73 can enhance the physical connection strength between the base 10 and the handlebar tube 71, which can ensure that the steering unit can remain stable even under high-intensity vibration or impact conditions, so as to reduce signal distortion and functional failure caused by loose connection; on the other hand, the synergistic effect of the anti-rotation member 13 and the locking member 73 further improves the anti-rotation performance of the system.

[0047] In some embodiments, the base 10 is provided with a mounting hole, and the locking member 73 passes through the mounting hole and is threadedly connected to the horizontal tube 71; wherein, the locking member 73 is a countersunk screw.

[0048] In some embodiments, such as Figures 1 to 6 As shown, the steering unit includes: a light-emitting component, including a base 10 and a light-emitting element 20 disposed on the base 10, the base 10 being configured to be detachably mounted on the handlebar tube 71; and an end cap component 30 located at the outer end of the base 10, the end cap component 30 being threadedly connected to the base 10.

[0049] In the above technical solution, the end cap component 30 can be threadedly connected to the base 10 to form a steering unit. Then, the steering unit is installed on the base 10 as a whole. This avoids the situation of assembling the light-emitting component and the end cap component 30 separately, and also eliminates the need to manually press the light-emitting component onto the handlebar tube 71 during the assembly process. This reduces the assembly difficulty and the probability of losing parts during the assembly process. In this way, it can solve the problems of complicated assembly steps, inconvenient assembly, and easy loss of parts in the steering unit assembly.

[0050] Furthermore, not only can a reliable connection between the end cap component 30 and the base 10 be achieved, but the replaceability of the end cap component 30 can also be achieved. The replaceable end cap component 30 also increases the personalization and playability of the scooter's appearance. The end cap component 30 can be selected with different colors, materials and patterns.

[0051] It should be noted that the handlebar assembly also includes a handle sleeve disposed on the outer periphery of the handlebar 71. Along the axial direction of the handlebar 71, the base 10 has an inner end and an outer end disposed opposite to each other. The inner end is disposed toward the handle sleeve of the handlebar, and the outer end is the end of the base 10 away from the handle sleeve.

[0052] In some embodiments, such as Figure 1 As shown, the end cap component 30 is a cylindrical structure with one end open and the other end closed. The base 10 includes a mounting cylinder 11 and a connecting cylinder 12 connected to the mounting cylinder 11. The mounting cylinder 11 and the connecting cylinder 12 are sleeved on the end of the horizontal tube 71. The mounting cylinder 11 is provided with a light-emitting body 20. The end cap component 30 is threaded to the outer periphery of the connecting cylinder 12.

[0053] In the above technical solution, the threaded connection between the outer periphery of the connecting cylinder 12 and the end cap component 30 can not only effectively disperse external forces to reduce damage to the light-emitting body 20, but also achieve a firm connection and convenient disassembly between components.

[0054] Of course, in another embodiment not shown, the connecting sleeve 12 may also be threaded onto the outer periphery of the end cap member 30.

[0055] In some embodiments, such as Figure 1 As shown, the outer diameter of the mounting cylinder 11 is larger than the outer diameter of the connecting cylinder 12. There is a stepped surface between the connecting cylinder 12 and the mounting cylinder 11. The stepped surface is used to axially limit the end cap component 30.

[0056] The above settings ensure that the end cap component 30 is difficult to move excessively along the axial direction when assembled, thereby avoiding damage to the end cap component 30.

[0057] Of course, in another embodiment not shown, the outer diameter of the mounting cylinder 11 can also be equal to the outer diameter of the connecting cylinder 12.

[0058] Of course, in another embodiment not shown, the base 10 may only include the mounting cylinder 11, and the end cap member 30 may include a first cylinder segment and a second cylinder segment connected to each other and having successively decreasing outer diameters. There is a stepped surface between the first cylinder segment and the second cylinder segment. The mounting cylinder 11 is threaded to the outer periphery of the second cylinder segment, and the end face of the mounting cylinder 11 abuts against the stepped surface.

[0059] In existing technologies, turn signals typically integrate components such as the LED chip and LED board onto a lamp holder, which is then welded to the outer lamp housing. During use, if a vehicle experiences a side fall, the impact force is directly transmitted to the lamp holder and LED chip, easily causing damage to the chip. Furthermore, the lamp housing cannot be replaced separately, leading to high after-sales costs. Therefore, in some embodiments, such as... Figure 1 As shown, the steering unit also includes a buffer 40 located on the outer periphery of the connecting cylinder 12, and the buffer 40 is located between the end cap member 30 and the stepped surface.

[0060] In the above technical solution, the elastic deformation of the buffer 40 can efficiently absorb and mitigate the instantaneous impact force caused by unexpected events such as vehicle side falls or collisions, effectively preventing the impact energy from being directly transmitted to the light emitter 20 and other key electronic components. This can reduce the probability of device damage and functional failure caused by external forces, thereby reducing maintenance costs.

[0061] In some embodiments, the buffer 40 is made of an elastic material and is a shock-absorbing pad (different materials, hardness and elasticity pads can be replaced according to actual product requirements).

[0062] In some embodiments, such as Figure 1 and Figure 4 As shown, a mounting portion 50 is provided on the outer periphery of the base 10, and the light-emitting element 20 is mounted on the base 10 through the mounting portion 50. In this way, the light-emitting element 20 can be mounted on the base 10.

[0063] In some embodiments, such as Figure 1 and Figure 4 As shown, the mounting part 50 is a mounting groove, the light-emitting body 20 is mounted in the mounting groove, and the bottom wall of the mounting groove is provided with a wire hole 51 that communicates with the inside of the horizontal tube.

[0064] In the above technical solution, the wire hole 51 can ensure the connection between the light-emitting body 20 and the internal circuit, and can reduce the corrosion and wear of the wires by the external environment. At the same time, the design of the mounting groove makes the installation process of the light-emitting body 20 simpler, and can achieve fast and accurate assembly without complicated positioning tools, which greatly improves production efficiency.

[0065] Example 1

[0066] In Example 1, as Figure 1 and Figure 2 As shown, the light-emitting element 20 is either interference-fitted or snap-fitted into the mounting groove. This allows the light-emitting element 20 to be directly pressed into the mounting groove, facilitating assembly.

[0067] In Embodiment 1, the wire hole 51 is connected to the interior of the horizontal tube 71 through the interior of the base 10, and the wire hole 51 is a round hole.

[0068] Compared to the traditional method of drilling holes in the lamp housing, in Embodiment 1, as shown... Figure 1 and Figure 2 As shown, the light-emitting element 20 can also be installed in the mounting groove by means of auxiliary installation such as screws, glue or ultrasonic welding, which has the advantages of higher structural strength, less detachment, convenient replacement and lower after-sales cost.

[0069] Example 2

[0070] In Example 2, as Figures 3 to 6 As shown, the mounting groove extends to the inner end of the base 10 away from the end cap member 30, and the light-emitting body 20 is slidably disposed in the mounting groove. In this way, by aligning the light-emitting body 20 with the mounting groove and pushing the light-emitting body 20, the light-emitting body 20 can be installed in the mounting groove, thereby improving the ease of installation of the light-emitting body 20.

[0071] In Example 2, as Figures 3 to 6 As shown, a limiting groove 53 is provided on the inner wall of the mounting groove, and a limiting part 54 is provided on the light-emitting body 20. The limiting groove 53 and the limiting part 54 are matched to limit each other to prevent the light-emitting body 20 from falling off.

[0072] In the above technical solution, by setting the limiting groove 53 and the limiting part 54 with limiting cooperation, the light-emitting body 20 can be prevented from falling off the base 10 radially due to vibration during vehicle operation, thus ensuring the continuous and reliable operation of the lighting system.

[0073] In the second embodiment, the handle on the horizontal tube 71 is located on the side where the inner end of the base 10 is located, and the handle presses the light-emitting body 20 into the mounting groove along the axial direction of the horizontal tube 71 to limit the axial position of the light-emitting body 20.

[0074] In Example 2, as Figure 6 As shown, the limiting groove 53 is connected to the mounting groove. The mounting groove is provided on both sides along the circumference of the base 10, and the mounting groove is provided on the side of the mounting groove away from the inner end of the base 10 along the axial direction of the base 10. In this way, the light-emitting body 20 can be radially limited from multiple positions.

[0075] Of course, in another embodiment not shown, a limiting groove 53 may be provided on the light-emitting body 20, and a limiting part 54 may be provided on the inner wall of the mounting groove. The limiting groove 53 and the limiting part 54 are matched to limit the light-emitting body 20 to prevent it from falling off. In this way, the light-emitting body 20 can also be limited.

[0076] like Figure 1 and Figure 2 As shown, the light-emitting element 20 can also be installed in the mounting slot by means of screws, glue or mechanical clips to increase the installation stability of the light-emitting element 20.

[0077] In Example 2, as Figure 4 As shown, the wire hole 51 is connected to the interior of the horizontal tube 71 through the interior of the base 10. The wire hole 51 is an elongated hole that extends to the inner end of the base 10 away from the end cap member 30.

[0078] In Embodiment 2, the light-emitting body 20 is laterally slidably inserted into the position through the mounting groove. Under extreme impact scenarios, the light-emitting body 20 has a certain amount of room for movement in the axial direction of the horizontal tube 71, which can effectively reduce the risk of damage caused by direct impact.

[0079] In Example 2, compared with ultrasonic welding, the structure using the sliding installation method has higher structural strength, is less prone to falling off, is easy to replace, and has lower after-sales costs.

[0080] It should be noted that Chinese utility model patent CN217198509U discloses a handlebar assembly and a vehicle. In this invention, a plastic mounting piece extends axially from the turn signal to fix it to the handlebar. Since the plastic mounting piece is integral with the turn signal, it will be the primary point of impact during a side fall, with the stress point being only the mounting hole. Both the material and the stress conditions result in low reliability. In contrast, in this application, the base 10 is connected to the handlebar 71 via a locking member 73, and the base 10 is connected via threads. The end cap component 30 is connected to the base 10, and a shock-absorbing pad is designed between the end cap component 30 and the base 10. Under side impact, the threads and the shock-absorbing pad can play a role in shock absorption, thereby improving the impact resistance of the steering unit. In the Chinese utility model patent with publication number CN217198509U, the end cap is directly fixed to the handle tube (rigid) by screws, while in this application, the end cap component 30 and the base 10 are connected by threads. In addition, this application adopts a single light source and mounting groove, so that the light source or the base can be repaired or replaced separately in the later stage, thereby reducing maintenance costs.

[0081] Chinese utility model patent CN214690004U discloses a handlebar assembly and a scooter. In this patent, the turn signal is fixed by a handlebar sleeve and an end cap. The handlebar sleeve is often made of flexible material, which can easily cause the turn signal to move axially. In this application, the base 10 is connected to the handlebar tube by screws, which can prevent axial movement. In the aforementioned patent, the end cap is directly and rigidly connected to the handlebar tube of the scooter by screws, which is easily damaged under side impact. In this application, a buffer 40 is designed between the end cap component 30 and the base 10, which can play a certain role in shock absorption and thus prevent damage to the end cap component 30 and the light-emitting component. In addition, this application can also reserve a screw connection interface between the end cap component 30 and the handlebar tube 71 to prevent the end cap component 30 from being accidentally unscrewed.

[0082] Chinese utility model patent CN218671833U discloses a turn signal, a turn signal assembly, and a mobility scooter. In that patent, the lamp body is clamped between an end cap and a base and fixed with screws, which can lead to cumbersome operation and inconvenience. In this application, the light-emitting element is mounted on a base 10, and the end cap component 30 is threadedly connected to the base 10, thus improving assembly convenience. In the aforementioned patent, the lamp housing has two holes on the side for installing LED chips; in this application, the base 10 provides mounting slots (for mounting...). The light-emitting element and the base 10 are fixed by bonding, ultrasonic welding or snap-fitting, which makes installation more convenient and the overall strength is higher. The above patent includes a limiting component that abuts between the light-emitting components to provide support and limit the lamp housing. The two light-emitting modules are pressed and fixed in the lamp hole of the base by the limiting component, which makes the assembly more difficult. In this application, the light-emitting element 20 is embedded in the base 10 by the mounting groove and reinforced by bonding, snap-fitting or ultrasonic welding, which makes it less likely to fall off. The lamp body can be replaced separately after the sale, which reduces the maintenance cost and also reduces the assembly difficulty.

[0083] This utility model has at least the following beneficial effects: the end cap component can be threadedly connected to the base to form a steering unit, and then the steering unit can be installed on the base as a whole. This avoids the situation of assembling the light-emitting component and the end cap component separately, and also eliminates the need to manually press the light-emitting component onto the handlebar during the assembly process. This reduces the assembly difficulty and the probability of losing parts during the assembly process, thereby solving the problems of complicated assembly steps, inconvenient assembly, and easy loss of parts in the steering unit assembly.

[0084] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
