[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following is a reference appendix. Figures 1 to 4 This invention describes a vehicle frame assembly and a personal mobility vehicle according to embodiments of the present invention.

[0026] like Figures 1 to 4 As shown, the frame assembly of this utility model embodiment includes: a front fork 1, a frame 2, and a steering mechanism 3. The front fork 1 is rotatably connected to the frame 2. The steering mechanism 3 includes a drive member 31, a first link 32, and a second link 33. The first end of the first link 32 is fixedly connected to the front fork 1. The drive member 31 is disposed at the second end of the first link 32. The output end of the drive member 31 is rotatably connected to the first end of the second link 33. The second end of the second link 33 is rotatably connected to the frame 2. The drive member 31 can drive the second link 33 to rotate to adjust the steering angle of the front fork 1.

[0027] According to the frame assembly of the present invention, the first link 32, the second link 33, the front fork 1 and the frame 2 can form a multi-link mechanism. Under the rotation of the drive member 31, the second link 33 can drive the first link 32 to move, so as to adjust the steering angle of the front fork 1. Thus, the frame assembly of the present invention can realize the automatic steering of the commuter vehicle, requires less space, and helps to reduce the overall weight of the commuter vehicle.

[0028] It is understandable that the four-bar linkage consisting of the first link 32, the second link 33, the front fork 1, and the frame 2 has 1 degree of freedom. The drive component 31, as a power source, can drive the four-bar linkage to move so that the front fork 1 can rotate synchronously, thereby changing the steering angle of the mobility scooter.

[0029] It should be noted that the mobility scooter is equipped with a balance controller, which can control the drive component 31 to achieve the function of dynamic balance of the mobility scooter through control algorithms.

[0030] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the drive unit 31 includes a drive motor 311 and a motor rocker arm 312. The output shaft of the drive motor 311 is fixedly connected to the first end of the motor rocker arm 312, and the second end of the motor rocker arm 312 is rotatably connected to the first end of the second link 33. It can be understood that the drive motor 311 can drive the second link 33 to rotate via the motor rocker arm 312, making the rotation of the second link 33 smoother and preventing jamming during the rotation of the four-bar linkage consisting of the first link 32, the second link 33, the front fork 1, and the frame 2.

[0031] Optionally, such as Figure 3 and Figure 4 As shown, the drive component 31 also includes a shim 313, which is detachably installed between the output shaft of the drive motor 311 and the motor rocker arm 312. This improves the uniformity of force distribution on the output shaft of the drive motor 311 and the motor rocker arm 312 after installation, and also facilitates subsequent disassembly and maintenance.

[0032] like Figure 2 and Figure 4 As shown, the steering mechanism 3 also includes a first fastener 341, which is detachably mounted on the motor rocker arm 312 and the second connecting rod 33. At least one of the motor rocker arm 312 and the second connecting rod 33 is rotatably connected to the first fastener 341. This facilitates the assembly and disassembly of the motor rocker arm 312 and the second connecting rod 33, making subsequent maintenance of the steering mechanism 3 convenient. Since at least one of the motor rocker arm 312 and the second connecting rod 33 is rotatably connected to the first fastener 341, the first fastener 341 can be used as a pivot shaft, allowing the motor rocker arm 312 to rotate relative to the second connecting rod 33.

[0033] For example, the first fastener 341 may be a screw, which is rotatably inserted through the motor rocker arm 312 and the second connecting rod 33.

[0034] Optionally, such as Figure 2 and Figure 4 As shown, the steering mechanism 3 also includes a second fastener 342, which is detachably inserted through the second link 33 and the frame 2, and at least one of the second link 33 and the frame 2 is rotatably connected to the second fastener 342.

[0035] This facilitates the assembly and disassembly of the second link 33 and the frame 2, making subsequent maintenance of the steering mechanism 3 easier. Since at least one of the second link 33 and the frame 2 is rotatably connected to the second fastener 342, the second fastener 342 can be used as a pivot to allow the second link 33 to rotate relative to the frame 2.

[0036] For example, the second fastener 342 may be a screw that rotates through the second link 33 and the frame 2.

[0037] Optionally, such as Figure 3 As shown, the steering mechanism 3 also includes a first bearing 351, which is disposed on at least one of the motor rocker arm 312 and the second connecting rod 33, and a first fastener 341 passes through the first bearing 351. This reduces the resistance when the motor rocker arm 312 and the second connecting rod 33 rotate relative to each other, and improves the smoothness of the relative rotation of the motor rocker arm 312 and the second connecting rod 33.

[0038] like Figure 3 As shown, the steering mechanism 3 also includes a second bearing 352, which is disposed on at least one of the second link 33 and the frame 2, and a second fastener 342 passes through the second bearing 352. This reduces the resistance when the second link 33 and the frame 2 rotate relative to each other, and improves the smoothness of the relative rotation of the second link 33 and the frame 2.

[0039] Optionally, such as Figure 2 and Figure 4 As shown, the first link 32 includes a first segment 321 and a second segment 322 connected together. The extension direction of the first segment 321 and the extension direction of the second segment 322 have a preset angle. The first segment 321 is detachably connected to the front fork 1, and the drive member 31 is located on the second segment 322. Because there is a preset angle between the extension direction of the first segment 321 and the extension direction of the second segment 322, it is easier to assemble the first link 32 and the front fork 1 together, which improves the stability of the connection between the first link 32 and the front fork 1. Furthermore, the four-bar linkage formed by the first link 32, the second link 33, the front fork 1, and the frame 2 moves more smoothly and has a better force distribution effect.

[0040] For example, the preset angle between the extension direction of the first segment 321 and the extension direction of the second segment 322 is 90°.

[0041] Optionally, such as Figure 2 and Figure 4 As shown, the steering mechanism 3 also includes a third fastener 343 and a fourth fastener 344. The third fastener 343 is detachably inserted through the front fork 1 and the first section 321, which facilitates the assembly and disassembly of the front fork 1 and the first link 32 for later maintenance.

[0042] The fourth fastener 344 is detachably inserted into the drive member 31 and the second segment 322, thereby facilitating the assembly and disassembly of the drive member 31 and the first connecting rod 32 for later maintenance.

[0043] Optionally, such as Figure 2 and Figure 4 As shown, the frame 2 includes a frame body 21 and an adapter 22. The adapter 22 is located on the side of the frame body 21 near the front fork 1, and the second end of the second link 33 is rotatably connected to the adapter 22. This facilitates the assembly of the frame 2 and the second link 33 together, making the four-bar linkage consisting of the first link 32, the second link 33, the front fork 1, and the frame 2 move more smoothly and have better force distribution.

[0044] For example, the adapter 22 is welded to the frame body 21.

[0045] like Figure 1 As shown, in this embodiment of the present invention, the front fork 1 of the frame assembly is in the center position. At this time, the front fork 1 is neither turned to the left nor to the right, and the mobility scooter can move forward normally.

[0046] When a modern mobility scooter needs to turn left, such as Figure 2 As shown, under the rotation of the drive component 31, the second link 33 can drive the first link 32 to move, that is, the second link 33 drives the first end of the first link 32 to move to the left, so as to adjust the leftward steering angle of the front fork 1. Figure 2 As shown, in this embodiment of the present invention, the front fork 1 of the frame assembly is deflected 45° to the left.

[0047] When a modern mobility scooter needs to turn right, such as Figure 3 As shown, under the rotation of the drive component 31, the second link 33 can drive the first link 32 to move, that is, the second link 33 drives the first end of the first link 32 to move to the right, so as to adjust the rightward steering angle of the front fork 1. Figure 3 As shown, in this embodiment of the present invention, the front fork 1 of the frame assembly is deflected 45° to the right.

[0048] Another embodiment of the present invention includes a mobility scooter comprising the frame assembly of the present invention.

[0049] According to the embodiment of the present invention, the first link 32, the second link 33, the front fork 1 and the frame 2 can form a multi-link mechanism. Under the rotation of the drive member 31, the second link 33 can drive the first link 32 to move, so as to adjust the steering angle of the front fork 1. Thus, the frame assembly of the embodiment of the present invention can realize the automatic steering of the mobility scooter, requiring less space and helping to reduce the overall weight of the mobility scooter.

[0050] For example, the mobility scooter is a two-wheeled electric vehicle, a two-wheeled scooter, or a two-wheeled motorcycle.
