[0027] 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.

[0028] Please refer to the following Figures 1 to 6 A vehicle frame and a mobility scooter having the same according to an embodiment of the utility model.

[0029] like Figures 1 to 6 As shown, the frame of the embodiment of the utility model is an integral die-casting, and the frame includes a frame body 1 and a pedal 2. The frame body 1 includes a head tube 11, an oblique tube 12 and two longitudinal beams 13, the two longitudinal beams 13 extend in the front-to-back direction and are arranged at intervals in the left-to-right direction, the rear end of the oblique tube 12 is connected to the longitudinal beam 13, and the front end of the oblique tube 12 is connected to the head tube 11. The pedal 2 includes a pedal body 21 and a plurality of first reinforcing ribs 22, the pedal body 21 is arranged on the upper side of the longitudinal beam 13, the two longitudinal beams 13 and the pedal body 21 define a mounting cavity 24, the plurality of first reinforcing ribs 22 are arranged in the mounting cavity 24, and the first reinforcing ribs 22 are connected to the pedal 2 and the two longitudinal beams 13.

[0030] like Figure 3 As shown, the mounting cavity 24 can be used to mount components such as a boost module, a controller, and a battery.

[0031] The frame of the embodiment of the utility model is an integrated die-casting, which can avoid the problems of complex processing, easy deformation, and low positioning accuracy during frame manufacturing compared to a welded frame. Since the two longitudinal beams 13 and the pedal body 21 define a mounting cavity 24, a plurality of first reinforcing ribs 22 are arranged in the mounting cavity 24, and the first reinforcing ribs 22 are connected to the pedal 2 and the two longitudinal beams 13. When the frame is die-cast, the position of the first reinforcing ribs 22 corresponding to the die-casting mold can facilitate the circulation of molten metal liquid to ensure that the molten metal liquid fills the entire cavity of the die-casting mold, thereby greatly reducing the probability of die-casting defects in the frame and improving the yield rate during frame production.

[0032] On the other hand, since a plurality of first reinforcing ribs 22 are arranged in the mounting cavity 24 to support the pedal body 21 , the structural strength of the pedal 2 can be ensured without increasing the thickness of the pedal body 21 , thereby reducing the material used for the frame and the weight of the frame.

[0033] For example, Figure 3 and Figure 6 As shown, a plurality of first reinforcing ribs 22 are crisscrossedly arranged in the mounting cavity 24 to further ensure the structural strength of the pedal body 21 and improve the bearing capacity of the pedal 2. In addition, the crisscrossed first reinforcing ribs 22 can also improve the smoothness of the flow of molten metal and reduce the problem of die-casting defects on the frame.

[0034] In the example of the present application, the plurality of first reinforcing ribs 22 are arranged in a checkerboard shape.

[0035] Optionally, in the width direction of the pedal body 21 (eg Figure 3 In the left and right direction), the two longitudinal beams 13 are spaced apart from the corresponding sides of the pedal body 21 by a preset distance to define a first installation area 25. It can be understood that there are two first installation areas 25 and they are arranged on both sides of the width direction of the pedal body 21 respectively.

[0036] like Figure 3 As shown, the width of the pedal body 21 is greater than the spacing between the two longitudinal beams 13, and the pedal 2 is located directly above the two longitudinal beams 13. Since the side edges of the longitudinal beams 13 are spaced apart from the side edges of the pedal body 21 by a preset distance, on the one hand, the width dimension of the pedal body 21 can be increased, and on the other hand, it is convenient to install components matching the frame at the position of the first installation area 25 to optimize the spatial arrangement of the components.

[0037] like Figures 1 to 3As shown, the pedal 2 further includes a plurality of second reinforcing ribs 23, which are arranged in the first mounting area 25 and connected to the longitudinal beam 13 and the pedal body 21. The second reinforcing ribs 23 can reinforce the structure of the side edges of the pedal body 21 to improve the structural strength of the left and right sides of the pedal body 21.

[0038] For another example, a plurality of second reinforcing ribs 23 are arranged at intervals along the front-to-back direction of the first mounting area 25, and the extending direction of the second reinforcing ribs 23 is parallel to the width direction of the pedal body 21 (eg Figure 3 It can be understood that the two adjacent reinforcing ribs and the edges of the longitudinal beam 13 and the pedal body 21 generally form a trapezoidal or parallelogram structure, thereby making the support structure of the second reinforcing rib 23 more stable.

[0039] Alternatively, if Figure 2 and Figure 4 As shown, a positioning reference hole 211 is provided on the pedal body 21. The positioning reference hole 211 is arranged on one side of the width direction of the pedal body 21. The positioning reference hole 211 penetrates the pedal body 21 in the up-down direction and is connected to the first mounting area 25. The positioning reference hole 211 is used to provide a positioning reference for the machining and inspection of the frame, and the positioning reference hole 211 can be used to install a nameplate. It can be understood that the positioning reference hole 211 has two functions. One is to provide a positioning reference for the machining and inspection of the frame, facilitate the positioning operation of the processing tooling and the circulation tooling, and improve the accuracy of the subsequent processing and inspection of the frame. The second is that a nameplate can be riveted at the positioning reference hole 211 to meet the regulatory requirements for the production of mobility scooters.

[0040] Alternatively, if Figure 2 and Figure 4 As shown, the rear end of the pedal 2 has a tail wing 26, which gradually extends upward from the front to the back. It can be understood that the tail wing 26 is tilted at a certain angle from the front to the back to increase the safe stepping area of ​​the pedal 2.

[0041] Furthermore, if Figure 2 and Figure 4 As shown, the upper end of the tail wing 26 is provided with a hanging tongue 261, and the hanging tongue 261 is used to connect with the handlebar hook after folding. It can be understood that when the handlebar of the scooter is folded backward, the hook on the handlebar can be hung on the hanging tongue 261 to improve the stability of the scooter after folding. And because the hanging tongue 261 is integrated during the die casting of the frame, the number of parts to be assembled can be reduced, and the production cost can be reduced.

[0042] Alternatively, if Figure 2 and Figure 6 As shown, the rear end of the longitudinal beam 13 is provided with a rear fork cantilever mounting hole 131 and a shock-absorbing preload mounting hole 132. Figure 2 As shown, each longitudinal beam 13 corresponds to a set of rear fork cantilever mounting holes 131 and shock absorber preload mounting holes 132 .

[0043] The rear fork cantilever mounting hole 131 is used to mount the rear fork cantilever. In the example of the present application, there are two rear fork cantilever mounting holes 131, and the angle between the arrangement direction of the two rear fork cantilever mounting holes 131 and the pedaling plane of the pedal 2 is between 30°-35°, thereby improving the stability of the rear fork cantilever mounting.

[0044] The shock-absorbing preload installation hole 132 is used to install the shock absorber. In the example of the present application, the angle between the arrangement direction of the shock-absorbing preload installation hole 132 and the vertical direction of the frame is between 3° and 7° to improve the shock-absorbing effect of the shock absorber.

[0045] Alternatively, if Figure 4 As shown, the rear end of the pedal body 21 is provided with an avoidance hole 262, which opens toward the rear end of the pedal body 21 and is used to avoid the rear fender. It can be understood that the avoidance hole 262 can avoid interference with the installation of the rear fender.

[0046] like Figure 1 and Figure 2 As shown, a shelf installation position 213 is provided on the pedal body 21, and the shelf installation position 213 is provided on one side of the width direction of the pedal body 21 and is arranged adjacent to the rear end of the pedal body 21. For example, there are two shelf installation positions 213, and the two shelf installation positions 213 are respectively arranged on both sides of the width direction of the pedal body 21. The frame of the embodiment of the utility model can meet the use needs of different users by providing the shelf installation position 213.

[0047] like Figure 3 As shown, a foot support mounting position 212 is provided on the pedal body 21, and the foot support mounting position 212 is provided on one side in the width direction of the pedal body 21. The mounting surface of the foot support mounting position 212 is parallel to the treading plane of the pedal body 21 to improve the stability of the foot support after supporting the ground.

[0048] In some embodiments, Figure 3 and Figure 5 As shown, a wiring cavity 121 is provided in the oblique tube 12, and the wiring cavity 121 is communicated with the installation cavity 24. An open port 122 is provided on the lower side of the oblique tube 12 and is communicated with the wiring cavity 121. One end of the open port 122 extends to the head tube 11, and the other end of the open port 122 extends to the pedal body 21. It can be understood that the cross section of the oblique tube 12 is generally a C-shaped structure, which can facilitate the arrangement of the wiring in the oblique tube 12, thereby improving the convenience of assembling the frame.

[0049] like Figure 2As shown, a charging port 123 and a charging seat fixing hole 124 are provided on the upper side of the inclined tube 12. Both the charging port 123 and the charging seat fixing hole 124 are connected to the wiring cavity 121. There are two charging seat fixing holes 124, which are arranged on the front and rear sides of the charging port 123. The charging seat fixing hole 124 is used to install the charging seat, and the charging head of the charging seat corresponds to the charging port 123. The frame of the embodiment of the utility model can facilitate the installation and positioning of the charging seat by integrating the charging port 123 and the charging seat fixing hole 124 on the inclined tube 12.

[0050] like Figure 2 As shown, a threading hole 125 is provided on one side of the oblique tube 12 in the width direction, and the threading hole 125 is connected to the wiring cavity 121. It can be understood that the main control line, brake line, DC line and other lines can enter the wiring cavity 121 through the threading hole 125, thereby hiding the wiring harness to reduce the risk of dirt or damage to the wiring harness.

[0051] Alternatively, if Figure 3 As shown, the lower end of the head pipe 11 has a steering limiting mechanism 111, and the steering limiting mechanism 111 can limit the rotation of the front fork. For example, the steering limiting mechanism 111 can limit the rotation range of the front fork to about 60°.

[0052] like Figure 1 As shown, the angle between the axial direction of the head tube 11 and the upper surface of the pedal body 21 is A, 70°≤A≤80°. It can be understood that the head tube 11 gradually tilts backward from bottom to top. By limiting the angle between the axial direction of the head tube 11 and the upper surface of the pedal body 21 to between 70°-80°, the scooter can be made more stable when riding.

[0053] A walking vehicle according to another embodiment of the present invention comprises the frame of the present invention. For example, the walking vehicle is an electric scooter.

[0054] The frame of the scooter of the embodiment of the utility model is an integrated die-casting, which can avoid the problems of complex processing, easy deformation, and low positioning accuracy during frame manufacturing compared to the welded frame. And because the two longitudinal beams 13 and the pedal body 21 define a mounting cavity 24, a plurality of first reinforcing ribs 22 are arranged in the mounting cavity 24, and the first reinforcing ribs 22 are connected to the pedal 2 and the two longitudinal beams 13. When the frame is die-cast, the position of the first reinforcing ribs 22 corresponding to the die-casting mold can facilitate the circulation of molten metal liquid, so that the molten metal liquid fills the entire cavity of the die-casting mold, thereby greatly reducing the probability of die-casting defects in the frame. On the other hand, because the plurality of first reinforcing ribs 22 are arranged in the mounting cavity 24 to support the pedal body 21, the structural strength of the pedal 2 can be ensured without increasing the thickness of the pedal body 21, reducing the material used for the frame and reducing the weight of the frame.
