[0038] 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.

[0039] The following is in conjunction with the appendix Figures 1-5 The frame of the mobility scooter in this embodiment will be described in detail.

[0040] The vehicle frame of this utility model embodiment includes a first frame 1, a second frame 2, a front cover plate 41, an upper cover plate 42, and a connecting component 5. The first frame 1 and the second frame 2 are arranged opposite each other in the left-right direction. Both the first frame 1 and the second frame 2 include a first segment 31, a second segment 32, and a third segment 33 integrally formed and sequentially connected in the front-rear direction. At least a portion of the first segment 31 extends from bottom to top and is arranged at an upward angle. The second segment 32 extends in the front-rear direction, and at least a portion of the third segment 33 extends from front to back and is arranged at an upward angle. Both the first frame 1 and the second frame 2 are sheet metal parts. The front cover plate 41 connects the first segment 31 of the first frame 1 and the first segment 31 of the second frame 2. The upper cover plate 42 connects the second segment 32 of the first frame 1 and the second segment 32 of the second frame 2. The connecting component 5 connects the first frame 1 and the second frame 2.

[0041] The frame of the mobility scooter in this embodiment is constructed by integrally forming a first section 31, a second section 32, and a third section 33 for both the first frame 1 and the second frame 2. The first section 31 forms the front wheel mounting part of the mobility scooter, the second section 32 forms the load-bearing part of the mobility scooter, and the third section 33 forms the rear wheel mounting part of the mobility scooter. This ensures that the frame provides a mounting base while improving the structural strength of the frame. Moreover, since both the first frame 1 and the second frame 2 are sheet metal parts, they are connected as a whole by the front cover plate 41, the upper cover plate 42, and the connecting parts 5. This reduces the gap between the first frame 1 and the second frame 2 and the mounting parts inside the frame, thereby improving the space utilization of the frame.

[0042] Furthermore, the frame of the mobility scooter in this embodiment uses sheet metal parts as the main frame. The forming process of sheet metal parts is more flexible and is not limited by the minimum bending radius of the tubing. The shape of the frame can be adjusted according to the shape of the mounting components inside the frame and the cover parts outside the frame, thereby reducing the installation gap between the frame and the mounting components inside the frame, while also reducing the installation gap between the cover parts and the frame, improving the space utilization of the frame and facilitating the weight reduction of the frame.

[0043] Specifically, such as Figures 1-4 As shown, the first frame 1 is located to the left of the second frame 2, or to the right of the second frame 2. For ease of description, we will take the example of the first frame 1 being located to the left of the second frame 2. The rear end of the first segment 31 is connected to the front end of the second segment 32, and the rear end of the second segment 32 is connected to the front end of the third segment 33. The first segment 31, the second segment 32, and the third segment 33 are integrally formed, which helps to enhance the structural strength of the first frame 1 and the second frame 2 while improving manufacturing efficiency.

[0044] The left end of the front cover plate 41 is connected to the first section 31 of the first frame 1 located on the left, and the right end of the front cover plate 41 is connected to the first section 31 of the second frame 2 located on the right. The front cover plate 41 connects the first section 31 of the first frame 1 to the second section 32 of the second frame 2, thus connecting the front ends of the first frame 1 and the second frame 2. The left end of the upper cover plate 42 is connected to the second section 32 of the first frame 1, and the right end of the upper cover plate 42 connects to the second section 32 of the second frame 2. The upper cover plate 42 connects the second section 32 of the first frame 1 to the second section 32 of the second frame 2, thus connecting the middle section of the first frame 1 and the middle section of the second frame 2. The connecting component 5 connects between the first frame 1 and the second frame 2 to improve the connection stability of the first frame 1 and the second frame 2.

[0045] Optionally, both the front cover plate 41 and the upper cover plate 42 are sheet metal parts, which helps to increase the connection area between the first frame 1 and the second frame 2, thereby improving the connection strength between the first frame 1 and the second frame 2.

[0046] Optionally, the first frame 1, the second frame 2, the front cover plate 41, the upper cover plate 42, and the connecting parts 5 are all welded together.

[0047] In some embodiments, the first frame 1 and the second frame 2 further include a first reinforcing plate 34, the first reinforcing plate 34 being connected to the inner wall surface of the second section 32, the inner wall surface of the second section 32 being provided with a first protrusion 3211 protruding toward the interior of the frame in the left-right direction, and the first reinforcing plate 34 being provided with a first recess 341 recessed toward the interior of the frame, the first recess 341 cooperating with the first protrusion 3211.

[0048] Specifically, such as Figure 5 As shown, the first reinforcing plate 34 is disposed on the inner side of the second section 32. The second section 32 is provided with a first protrusion 3211 formed by stamping from the outer wall of the second section 32 toward the inside of the frame. The first reinforcing plate 34 is provided with a first recess 341 recessed toward the inside of the frame. By fitting the first protrusion 3211 of the second section 32 into the first recess 341 of the first reinforcing plate 34 and connecting the second section 32 and the first reinforcing plate 34, the structural strength of the second section 32 is improved.

[0049] Optionally, the first reinforcing plate 34 is a sheet metal part. By providing a first protrusion 3211 on the second section 32 and a first recess 341 on the first reinforcing plate 34, the gap between the first frame 1 and the second frame 2 and the mounting components inside the frame and the covering parts outside the frame is further reduced, which helps to improve the space utilization of the frame.

[0050] In some embodiments, the second segment 32 includes a first flange 322 formed by folding the upper edge of the main board 321 and the autonomous board 321 toward the inside of the frame. A first protrusion 3211 is formed on the main board 321. The lower surface of the first flange 322 is provided with a downwardly protruding second protrusion 3221. The upper cover plate 42 is provided with a second recess 421 opposite to the second protrusion 3221. The second recess 421 cooperates with the second protrusion 3221.

[0051] Specifically, such as Figures 1-5 As shown, the main board 321 extends in the vertical direction, and the first flange 322 extends from the upper edge of the main board 321 toward the inside of the frame. That is, the first flange 322 extends in the front-back direction. The first flange 322 is provided with a downward protruding second protrusion 3221. The second concave part 421 is opposite to and cooperates with the second protrusion 3221 to form a clearance part, which facilitates the installation of the pedals of the mobility scooter.

[0052] In some embodiments, the first frame 1 and the second frame 2 further include a second reinforcing plate 35, the third segment 33 has a first cavity opening toward the interior of the frame, the second reinforcing plate 35 has a second cavity 351 opposite to the first cavity, the second reinforcing plate 35 is connected to the third segment 33 and the first cavity communicates with the second cavity 351.

[0053] Specifically, such as Figure 1 and Figure 5 As shown, the second reinforcing plate 35 is disposed on the inner side of the third segment 33. The third segment 33 has a first cavity that opens toward the inside of the frame, and the second reinforcing plate 35 has a second cavity 351 that opens toward the outside of the frame. The outer peripheral edge of the third segment 33 is connected to the outer peripheral edge of the second reinforcing plate 35, and the first cavity and the second cavity 351 are connected. The arrangement of the first cavity and the second cavity 351 helps to enhance the rigidity of the third segment 33.

[0054] Optionally, the third segment 33 has a first edge surrounding the third segment 33 in a circumferential direction, and the second reinforcing plate 35 has a second edge surrounding the second reinforcing plate 35 in a circumferential direction, and the first edge is welded to the second edge.

[0055] Optionally, the second reinforcing plate 35 is a sheet metal part. The setting of the second reinforcing plate 35 helps to improve the structural strength of the third section 33.

[0056] In some embodiments, such as Figure 1 As shown, the third segment 33 extends from front to back and is arranged at an angle toward the inside of the frame. The distance between the third segment 33 of the first frame 1 and the third segment 33 of the second frame 2 in the left and right directions gradually decreases from front to back, forming a structure that is wide at the front and narrow at the back. The wide front setting facilitates the installation of the battery, and the narrow rear setting facilitates the matching of the third segment 33 with the overall appearance of the mobility scooter, improving its compactness.

[0057] In some embodiments, such as Figure 1 and Figure 3 As shown, the lower side of the end of the third segment 33 furthest from the second segment 32 is provided with a downwardly extending portion 331. In this embodiment, by providing the extension portion 331 on the rear side of the lower end of the third segment 33, it is convenient to improve the structural strength of the third segment 33 while avoiding the battery.

[0058] In some embodiments, such as Figure 1 As shown, the third segment 33 includes an inclined segment 332 and a parallel segment 333. The parallel segment 333 extends in the front-to-back direction, and the inclined segment 332 extends in the front-to-back direction and is arranged at an upward inclination. The front end of the inclined segment 332 is connected to the second segment 32, and the rear end of the inclined segment 332 is connected to the front end of the parallel segment 333.

[0059] In this embodiment, the inclined section 332 is arranged upward in the direction from front to back, and the parallel section 333 extends in the direction from front to back, which makes it easy to reserve installation space for the seat bucket and to securely install the front and rear ends of the seat bucket on the frame.

[0060] In some embodiments, the first frame 1 and the second frame 2 include a third reinforcing plate 36 and a fourth reinforcing plate 37, the third reinforcing plate 36 and the fourth reinforcing plate 37 are connected, the first segment 31 has a first bending surface 311 extending in the vertical direction, at least one of the first segment 31 and the second segment 32 has a second bending surface 312 extending in the front-back direction, the front end of the second bending surface 312 is connected to the upper end of the first bending surface 311, the third reinforcing plate 36 is connected to the first bending surface 311, and the fourth reinforcing plate 37 is connected to the second bending surface 312.

[0061] Specifically, such as Figures 3-5 As shown, the second bending surface 312 is formed on the inner upper wall of the first segment 31, or on the inner upper wall of the second segment 32, or on both the inner upper wall of the first segment 31 and the inner upper wall of the second segment 32. The first bending surface 311 extends in the vertical direction, and the second bending surface 312 extends in the front-rear direction. The upper end of the first bending surface 311 is connected to the front end of the second bending surface 312 to form a bending portion. The bending portion is relatively weak. By welding a third reinforcing plate 36 to the first bending surface 311 and a fourth reinforcing plate 37 to the second bending surface 312, and then welding the third reinforcing plate 36 and the fourth reinforcing plate 37 together, the structural strength of the bending portion of the frame is improved.

[0062] Optionally, the bent portion also has a third bent surface extending in the front-back direction and in the up-down direction. The upper end of the third bent surface is connected to the second bent surface 312, and the front end of the third bent surface is connected to the first bent surface 311. One end of the third reinforcing plate 36 and one end of the fourth reinforcing plate 37 can both be welded to the third bent surface. Taking the third reinforcing plate 36 and the fourth reinforcing plate 37 installed on the first frame 1 as an example, the first bending surface 311 extends in the vertical direction, the second bending surface 312 extends in the front-back direction and is located above the first bending surface 311, the front end of the second bending surface 312 is connected to the upper end of the first bending surface 311, the third bending surface is located to the left of the first bending surface 311 and the second bending surface 312, the front end of the third bending surface is connected to the left end of the first bending surface 311, the upper end of the third bending surface is connected to the left end of the second bending surface 312, the third reinforcing plate 36 is welded to the first bending surface 311 and the left end of the third reinforcing plate 36 is welded to the third bending surface, the fourth reinforcing plate 37 is welded to the second bending surface 312 and the left end of the fourth reinforcing plate 37 is welded to the third bending surface, and the rear end of the third reinforcing plate 36 is welded to the front end of the fourth reinforcing plate 37.

[0063] This embodiment, by providing a first reinforcing plate 34, a second reinforcing plate 35, a third reinforcing plate 36, and a fourth reinforcing plate 37 on the first segment 31, the second segment 32, and the third segment 33, can avoid stress concentration in the first segment 31, the second segment 32, and the third segment 33, and improve the structural strength of the first segment 31, the second segment 32, and the third segment 33.

[0064] In some embodiments, such as Figure 5 As shown, the first frame 1 and the second frame 2 also include a bushing 38, and the third section 33 has a mounting hole 334. The bushing 38 fits into the mounting hole 334 for mounting the rear wheel of the mobility scooter. The bushing 38 facilitates the mounting of the mobility scooter's horizontal fork, and thus facilitates the mounting of the rear wheel.

[0065] In some embodiments, such as Figure 5 As shown, the first frame 1 and the second frame 2 also include a shock absorber bracket 39, which is mounted on the third section 33. The shock absorber bracket 39 facilitates the installation of the shock absorber and improves installation convenience.

[0066] In some embodiments, the connecting component 5 includes a first mounting bracket 51 and a second mounting bracket 52. The first mounting bracket 51 is connected between the second section 32 of the first frame 1 and the second section 32 of the second frame 2 and is located behind the upper cover plate 42. The second mounting bracket 52 is connected between the third section 33 of the first frame 1 and the third section 33 of the second frame 2. The first mounting bracket 51 and the second mounting bracket 52 are used to install the seat bucket.

[0067] Specifically, such as Figure 1 As shown, the first mounting bracket 51 and the second mounting bracket 52 are arranged at intervals in the front-to-back direction, and the first mounting bracket 51 is located in front of and below the second mounting bracket 52. The front end of the seat is mounted on the first mounting bracket 51, and the rear end of the seat is mounted on the second mounting bracket 52. The arrangement of the first mounting bracket 51 and the second mounting bracket 52 improves the ease of installation of the seat.

[0069] Optionally, the first mounting bracket 51 is higher than the second section 32. That is, there is a certain height between the upper surface of the first mounting bracket 51 and the upper surface of the second section 32. The seat bucket is mounted using the first mounting bracket 51 to prevent the seat bucket from directly pressing on the battery inside the frame, thereby protecting the battery.

[0070] Optionally, the battery includes a battery body and a battery management system, with the battery management system located on top of the battery body for easy maintenance.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the connecting component 5 also includes a first pipe 53, which connects the lower end of the third section 33 of the first frame 1 and the lower end of the third section 33 of the second frame 2. The first pipe 53 strengthens the connection between the lower ends of the third section 33 of the first frame 1 and the second frame 2, and also makes the pipe easier to manufacture.

[0072] In some embodiments, such as Figure 1 and Figure 2 As shown, the connecting component 5 also includes a second pipe 54, which connects the upper end of the third section 33 of the first frame 1 and the upper end of the third section 33 of the second frame 2, and is located below the second mounting bracket 52. The second pipe 54 strengthens the connection between the upper ends of the third section 33 of the first frame 1 and the third section 33 of the second frame 2, and also simplifies the manufacturing of the pipe.

[0073] Optionally, the first pipe 53 and the second pipe 54 are welded to the first frame 1 and the second frame 2, so that the sheet metal parts are the main frame and the pipe parts are the locally reinforced frame. The forming process of the sheet metal parts makes the frame more compatible with the space requirements of the whole vehicle, which facilitates flexible layout and improves the space utilization of the frame, thereby improving the compactness of the commuter vehicle.

[0074] In some embodiments, the frame of the mobility scooter further includes a head tube 6, which is disposed on the upper half of the front cover plate 41. In this embodiment, by disposing of the head tube 6 on the upper half of the front cover plate 41, it is convenient to install handlebars and wheels.
