[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] Combine the following Figure 1 and Figure 2The invention describes a scooter steering return device according to an embodiment of the utility model.

[0028] The scooter steering return device of the embodiment of the utility model comprises a first bracket 1, a second bracket 2 and an elastic member. The first bracket 1 is used to be connected to the front fork 4 of the scooter, and the second bracket 2 is used to be connected to the frame 5 of the scooter. The elastic member is connected between the first bracket 1 and the second bracket 2, and the elastic member is located on the outer side of each of the front fork 4 and the frame 5. The front fork 4 is pivotally connected to the frame 5 and has a steering position and a return position. The elastic member is suitable for pressing the front fork 4 toward the return position.

[0029] According to the scooter steering return device of the embodiment of the utility model, the first bracket 1 and the second bracket 2 are respectively installed on the front fork 4 and the frame 5 of the scooter, and then the elastic member is connected between the first bracket 1 and the second bracket 2, so that the elastic member is located on the outside of each of the front fork 4 and the frame 5. At this time, when the front fork 4 rotates toward the steering position relative to the frame 5, the elastic member gives the front fork 4 a thrust to move toward the return position, thereby realizing the automatic return of the front fork 4 and the vertical tube and handlebar connected thereto. There is no need to set a contoured groove in the front fork 4, the structure of the scooter steering return device is simple, and it will not occupy the internal space of the front fork 4, ensuring the internal wiring function of the scooter. At the same time, by setting the elastic member on the outside of the front fork 4 and the frame 5, it is not necessary to disassemble the front fork 4 and its surrounding parts when disassembling the elastic member, and the after-sales cost is low.

[0030] In some embodiments, Figure 2 As shown, the elastic member includes a tension spring 3 , a first end of the tension spring 3 is connected to the first bracket 1 , and a second end of the tension spring 3 is connected to the second bracket 2 .

[0031] When the front fork 4 pivots from the return position to the steering position relative to the frame 5, the distance between the first bracket 1 and the second bracket 2 gradually increases, and then the tension spring 3 is gradually stretched to generate a pulling force for the front fork 4 to return to the return position, thereby realizing automatic return of the front fork 4. The design of the tension spring 3 further simplifies the structure of the steering return device of the scooter. Compared with elastic parts such as leaf springs that can also realize the return function, the tension spring 3 is smaller in size and lower in cost.

[0032] Specifically, the axial direction of the tension spring 3 is substantially consistent with the length direction of the scooter.

[0033] In some embodiments, Figure 2 As shown, the tension spring 3 includes a first hook, an elastic body and a second hook connected in sequence. The first bracket 1 is provided with a first mounting hole 11, and the second bracket 2 is provided with a second mounting hole 21. The first hook is hung on the first bracket 1 by passing through the first mounting hole 11, and the second hook is hung on the second bracket 2 by passing through the second mounting hole 21.

[0034] Therefore, the tension spring 3 can be disassembled by simply pulling out the first hook from the first mounting hole 11 and the second hook from the second mounting hole 21. The tension spring 3 and each of the first bracket 1 and the second bracket 2 are easy to disassemble and assemble, further reducing the after-sales maintenance cost of the tension spring 3.

[0035] Specifically, Figure 2 As shown, the first bracket 1 and the second bracket 2 respectively include a first connecting plate and a second connecting plate substantially perpendicular to the height direction of the scooter, the first connecting plate is provided with a first mounting hole 11, and the second connecting plate is provided with a second mounting hole 21, that is, the axial direction of the first mounting hole 11 and the second mounting hole 21 is substantially consistent with the height direction of the scooter.

[0036] In some embodiments, a third mounting hole is provided on the first bracket 1, and a fourth mounting hole is provided on the second bracket 2. The scooter steering return device further includes a first fastener and a second fastener, the first fastener passes through the third mounting hole and is connected to the front fork 4, and the second fastener passes through the fourth mounting hole and is connected to the frame 5.

[0037] That is, it is only necessary to form the third mounting hole and the fourth mounting hole on the first bracket 1 and the second bracket 2 respectively, and then they can be installed on the front fork 4 and the frame 5 respectively through the first fastener and the second fastener. The structure of the first bracket 1 and the second bracket 2 is simpler, and the disassembly and assembly cost on the scooter is lower.

[0038] Specifically, the first bracket 1 is generally an L-shaped plate, and the first mounting hole 11 and the third mounting hole are respectively arranged on two different connecting plates of the first bracket 1. The second bracket 2 is generally a U-shaped plate, and the second mounting hole 21 and the fourth mounting hole are respectively arranged on two opposite connecting plates of the second bracket 2.

[0039] In some embodiments, the first fastener and the second fastener are both screw threads.

[0040] Specifically, the threaded part is a bolt, a first threaded hole is provided on the front fork 4, and a second threaded hole is provided on the frame 5. The bolt passes through the first mounting hole 11 and is threadedly matched with the first threaded hole to achieve fixed installation of the first bracket 1 on the front fork 4, and the bolt passes through the second mounting hole 21 and is threadedly matched with the second threaded hole to achieve fixed installation of the second bracket 2 on the frame 5.

[0041] And / or, the number of the third mounting holes is at least two, and the number of the fourth mounting holes is at least two.

[0042] The design of at least two third mounting holes and the fourth mounting hole further improves the connection strength between the first bracket 1 and the front fork 4 , and further improves the connection strength between the second bracket 2 and the frame 5 .

[0043] Specifically, there are two third mounting holes and two fourth mounting holes, the two third mounting holes are arranged at intervals along the width direction of the scooter, and the two fourth mounting holes are arranged at intervals along the width direction of the scooter.

[0044] The scooter according to the embodiment of the utility model comprises a front fork 4 , a frame 5 and a scooter steering return device as in any of the above embodiments, the first bracket 1 is connected to the front fork 4 , and the second bracket 2 is connected to the frame 5 .

[0045] The technical advantages of the scooter according to the embodiment of the utility model are the same as the technical advantages of the scooter steering return device in the above embodiment, which will not be repeated here.

[0046] In some embodiments, Figure 1 As shown, the front fork 4 also includes a front fork tube 41 and a front fork body 42.

The front fork body 42 includes a left fork plate 421, an upper bracket 423 and a right fork plate 422 connected in sequence. The upper bracket 423 is connected to the lower end of the front fork tube 41, and the first bracket 1 is mounted on the upper bracket 423.

[0047] At this time, the elastic member is located at the rear side of the upper bracket 423 of the front fork 4 and away from the left fork plate 421 and the right fork plate 422. The elastic member has good concealment and will not interfere with the steering of the scooter.

[0048] In some embodiments, Figure 1 As shown, the frame 5 includes a head pipe 51, an oblique longitudinal beam 52 and a horizontal longitudinal beam 53 which are connected in sequence, wherein there is one oblique longitudinal beam 52 and the second bracket 2 is connected to the oblique longitudinal beam 52, or there are two oblique longitudinal beams 52, the frame 5 also includes a cross beam 54 connected between the two oblique longitudinal beams 52, and the second bracket 2 is installed at the center position of the cross beam 54.

[0049] When there is one oblique longitudinal beam 52, the oblique longitudinal beam 52 is located at the center of the frame 5 in the width direction of the frame 5. In other words, no matter whether there are one or two oblique longitudinal beams 52, the second bracket 2 is installed at the center of the frame 5 in the width direction, thereby ensuring that the end of the elastic member connected to the second bracket 2 is located at the center of the frame 5 in the width direction, so as to further reduce the probability of interference of the elastic member with the steering and other functions of the scooter.

[0050] Specifically, Figure 1 As shown, the elastic member includes a tension spring 3 , and the number of the tension spring 3 is one. When the front fork 4 is located at the return position, the tension spring 3 is located at the center position of the frame 5 in the width direction of the frame 5 .

[0051] In some embodiments, the first bracket 1 is welded to the front fork 4, or the first bracket 1 is connected to the front fork 4 via a screw. The second bracket 2 is welded to the frame 5, or the second bracket 2 is connected to the frame 5 via a screw.

[0052] That is, the first bracket 1 and the second bracket 2 can be welded to the upper bracket 423 and the cross beam 54 respectively to ensure the reliability of the installation of the first bracket 1 and the second bracket 2 on the scooter. The first bracket 1 and the second bracket 2 can also be detachably connected to the upper bracket 423 and the cross beam 54 respectively by screws, thereby facilitating the disassembly and assembly of the first bracket 1 and the second bracket 2.
