[0030] Example

[0031] Combined with Figure 1-8 A lightweight foldable scooter comprises a front wheel frame 10, a rear wheel frame 11 and a seat frame 12. The front wheel frame 11 is provided with a front wheel 13, the rear wheel frame 11 is provided with a rear wheel 14, and the seat frame 12 is provided with a seat 15.

[0032] The front wheel frame 10 and the rear wheel frame 11 are rotationally matched. When folding, the front wheel frame 10 and the rear wheel frame 11 will make the connection position between the front wheel frame 10 and the rear wheel frame 11 bulge. When the connection position between the front wheel frame 10 and the rear wheel frame 11 rises to the highest point, the front wheel frame 10 and the rear wheel frame 11 form a folded state that fits each other.

[0033] The front wheel frame 10 is composed of an arc frame 16 arranged parallel to the front wheel 13 and a front wheel mounting frame 17 connected to the arc frame 16. The arc frame 16 is located at the front and rear sides, and the front wheel mounting frame 17 is connected between the left sides of the arc frame 16 on both sides.

[0034] A handle mounting frame 18 is fixedly provided on the front wheel mounting frame 17, and a rotating collar 20 is hingedly provided on the handle mounting frame 18. The handle mounting frame 18 is used to change the rotation angle of the rotating collar 20, and the rotating collar 20 swings left and right.

[0035] A connecting bridge 50 is provided on the side between the arc frames 16 away from the front wheel 13. The connecting bridge 50 not only connects the arc frames 16, but also serves as an auxiliary support. At the same time, the connecting bridge 50 also assists in folding the scooter. The connecting bridge 50 is a major force point when the scooter is folded.

[0036] The connecting bridge 50 is hingedly provided with a mounting plate 19, the mounting plate 19 is a V-shaped member, and the protruding end of the mounting plate 19 is hingedly mounted on the connecting bridge 50. After receiving force, the mounting plate 19 swings on the connecting bridge 50, thereby performing a folding action.

[0037] A push rod 21 is provided between one end of the mounting plate 19 and the rotating collar 20. The push rod 21 is hinged between the mounting plate 19 and the rotating collar 20. When the push rod 21 is extended, the mounting plate 19 and the rotating collar 20 will both swing. As the push rod 21 is extended, since the hinge point connecting the rotating collar 20 and the push rod 21 is located below the hinge point connecting the rotating collar 20 and the handle mounting frame 18, the rotating collar 20 will swing to the right, and the mounting plate 19 will be directly pushed out by the push rod 21, thereby rotating to the right around the hinge point of the mounting plate 19.

[0038] The push rod 21 is an electric push rod, which can be extended. The pushing action is completed by the extension of the push rod 21. The extension of the push rod 21 causes the rotating ring 20 and the arc frame 16 to rotate, thereby starting the folding action of the scooter.

[0039] In a general embodiment, the push rod 21 adopts the form of a motor and a screw structure. The push rod 21 consists of a push rod housing 51, a motor 22, a motor output wheel 23, a screw 24, a screw drive wheel 26 and a pushing and fitting rod 25. The end of the pushing and fitting rod 25 is hinged to the rotating ring 20, and the right end of the push rod housing 51 is hinged to the mounting plate 19.

[0040] The screw rod 24 and the push-cooperating rod 25 are integrated by a threaded sleeve, and the screw rod 25 is extended and retracted by forward and reverse rotation, and the screw rod is driven by the motor output wheel 23 of the motor 22 and the screw rod transmission wheel 26.

[0041] The arc frame 16 of the front wheel frame 10 is deflected upward on the side away from the front wheel 13, and an abutment block 29 is provided on the inner side of the upward position of the end of the arc frame 16 that is deflected upward. The abutment block 29 is fixed on the arc frame 16, and the abutment block 29 plays a limiting role.

[0042] The rear wheel frame 11 includes a support frame 27 arranged in parallel with the rear wheel and a connecting frame 28 located between the support frames and connecting the support frames.

[0043] The other end of the mounting plate 19 is fixed to a connecting frame 28, so that the rotational force is transmitted to the connecting frame 28 when the mounting plate 19 rotates. Since the connecting frame 28 is fixedly connected to the mounting plate 19 and the supporting frame 27, the rotational force of the mounting plate 19 is directly transmitted to the supporting frame 27. Therefore, when the mounting plate 19 rotates to the right, since the supporting frame 27 cannot rotate to the right directly, the supporting frame 27 rotates to the right around the rear wheel, thereby causing the supporting frame 27 to rise upward.

[0044] The support frame 28 is located below the arc-shaped end of the arc-shaped frame 16, and the top end surface of the support frame 28 abuts against the abutment block 29. The limiting effect of the abutment block 29 prevents the support frame 28 from swinging downward, so that the support frame 28 plays a supporting role.

[0045] The seat frame 12 is composed of a load-bearing frame 30 and a swing frame 31 . The load-bearing frame 30 is composed of a vertical rod 32 and a seat mounting frame 33 . The seat mounting frame 33 is used to mount a seat cushion.

[0046] The vertical rod 32 is fixedly mounted below the side of the seat mounting frame 33 away from the rear wheel, and the vertical rod 32 is fixedly mounted on the lower side of the seat mounting frame 33 .

[0047] The vertical rod 32 of the load-bearing frame 30 is mounted to the end of the deflected end of the arc frame 16 away from the front wheel 12 , and the vertical rod 32 is hinged to the deflected end of the arc frame 16 .

[0048] The swing frame 31 is hinged to the rear wheel frame 11 on one side of the rear wheel 14, and a power mounting frame 52 is fixedly provided at one end of the support frame 27 located at the rear end. The power mounting frame 52 is installed obliquely, and the swing frame 31 is installed on the upper side of the power mounting frame 52.

[0049] An auxiliary wheel mounting frame 44 is also hingedly provided on the power mounting frame 52 . The auxiliary wheel mounting frame 44 is a mounting frame with a bending angle. The bending position of the auxiliary wheel mounting frame 44 is hingedly connected to the power mounting frame 52 .

[0050] The swing frame 31 is provided with a driving connection block 45, and the driving connection block 45 is installed on the left side of the swing frame 31. An auxiliary wheel L-shaped connection piece 46 is hinged between the driving connection block 45 and the top end of the auxiliary wheel mounting frame 44, and the L-shaped connection piece 46 is hinged to the auxiliary wheel mounting frame 44 toward the left.

[0051] A seat L-shaped connecting frame 34 is provided between the seat mounting frame 33 and the swing frame 31. One end of the seat L-shaped connecting frame 34 is hinged to the seat mounting frame 33, and the other end of the seat L-shaped connecting frame 34 is hinged to the swing frame 31 located on the upper side of the seat mounting frame 33. The seat L-shaped connecting frame 34 is used to assist the folding of the seat frame 12. The load-bearing frame 30 and the vertical rod 32 can be folded toward each other with the swing frame 31 under the action of the seat L-shaped connecting frame 34.

[0052] An auxiliary wheel 47 is rotatably provided at the end of the auxiliary wheel mounting frame 44. The auxiliary wheel 47 can not only prevent the scooter from tipping over when the scooter is driving normally, but also can be used as a moving wheel after the scooter is folded, so that the user can move the folded scooter conveniently.

[0053] When the support frame 27 swings to the right, the swing frame 31 swings to the left, and the load-bearing frame 30 and the vertical rod 32 swing to the right under the lifting of the arc frame 16. The load-bearing frame 30 swings to the right around the hinge point between the vertical rod 32 and the arc frame 16. At the same time, since the swing frame 31 swings to the left, the seat on the load-bearing frame 30 rotates toward the direction of the swing frame 31. When the folding is completed, the seating surface of the seat is in contact with or nearly in contact with the swing frame 31.

[0054] When the swing frame 31 rotates to the left, the swing frame 31 drives the auxiliary wheel mounting frame 44 to swing through the auxiliary wheel L-shaped connecting piece 46, and the auxiliary wheel 47 on the auxiliary wheel mounting frame 44 rotates upward around the hinge between the auxiliary wheel mounting frame 44 and the power mounting frame 52.

[0055] The handle mounting frame 18 is hingedly provided with a rotating collar 20, and a handle 35 is rotatably provided inside the rotating collar 20. The handle 35 is a telescopic handle used to control the movement direction and running speed of the scooter.

[0056] The handle 35 is preferably connected by adopting the form of two main bodies, and the two main bodies are installed in the form of one main body being sleeved in the other main body. The cooperation between the two main bodies can be in the form of buckle limitation or resistance limitation. When the handle needs to be raised, the buckle or resistance buckle is opened, the handle is pulled to rise, and then the buckle or resistance buckle is closed to fix the handle. The same applies when the handle needs to be lowered.

[0057] A wheel support frame 36 is fixedly provided on the rotating ring 20, and the wheel support frame 36 is used to enable the front wheel 13 to support the scooter. Wheel steering brackets 37 are rotatably provided at both ends of the support frame 36. The front wheel is rotatably installed on the outside of the wheel steering bracket 37. The wheel support frame 36 and the wheel steering bracket 37 keep the wheel in an upright state.

[0058] The wheel steering bracket 37 is assembled from two upper and lower support plates and a side plate. The front wheel 13 is mounted on the side plate. At least one of the support plates on the upper and lower sides is extended from the center position of the front wheel 13 to the edge position of the front wheel hub for controlling wheel steering.

[0059] Preferably, the support plate at the lower side is extended, and a first mounting point 40 is provided on the bottom plate of the wheel steering bracket 37 and located on the side of the wheel support bracket.

[0060] The rotating ring 20 extends from the lower end of the handle, and a steering plate 38 is fixedly provided at the bottom end of the handle. A second mounting point 39 is provided on the side of the steering plate 38 away from the handle 35, and a steering link 41 is hinged between the first mounting point 40 and the second mounting point 39. The handle 35 rotates to drive the steering plate 38 to rotate, and the deflection formed by the rotation of the steering plate 38 is reflected to the wheel steering bracket 37 through the steering connection 41, and the steering of the front wheel 13 is achieved by the deflection of the wheel steering bracket 37.

[0061] A rear wheel mounting frame 42 is further provided on a side of the support frame 11 away from the front wheel. A driving motor 43 is provided on the rear wheel mounting frame 42 . The rear wheel 14 is fixedly provided on a driving shaft of the driving motor 43 .

[0062] The drive motor 43 can be in various forms, and can be a single-axis drive motor or a dual-axis drive motor.

[0063] When a single-axis drive motor is used, the rear wheel shaft is installed on the power mounting frame 52, and the single-axis drive motor drives the rear wheel shaft, thereby realizing the driving of the rear wheel.

[0064] When it is a dual-axis drive motor, the dual-axis drive motor can be directly mounted on the power mounting frame 52, and the rear wheel can be directly mounted on the dual-axis drive motor, and the rear wheel is directly driven by the dual-axis drive motor.

[0065] The folding state of the scooter is switched as follows:

[0066] The push rod 21 is opened to extend the push rod 31, so the rotating ring 20 will swing to the right, thereby causing the handle 35 to swing to the right, and at the same time, the arc frame 16 and the support frame 27 swing upward toward the connection between the mounting plate 19 and the support frame 28. At this time, when the support frame 27 swings to the right, the swing frame 31 swings to the left, and the load-bearing frame 30 and the vertical rod 32 swing to the right under the lifting of the arc frame 16. The load-bearing frame 30 swings to the right around the hinge point between the vertical rod 32 and the arc frame 16. At the same time, because the swing frame 31 swings to the left, the load-bearing frame 3 0 rotates toward the swing frame 31, and the seating surface of the seat is in contact with or nearly in contact with the swing frame 31. When the swing frame 31 rotates to the left, the swing frame 31 drives the auxiliary wheel mounting frame 44 to swing through the auxiliary wheel L-shaped connecting piece 46, and the auxiliary wheel 47 on the auxiliary wheel mounting frame 44 rotates upward around the hinge between the auxiliary wheel mounting frame 44 and the power mounting frame 52 to complete the folding. At this time, the folded scooter has only the front wheel 13 and the auxiliary wheel 47 touching the ground. When the user needs to use the handle 35 to move the folding scooter, the handle 35 does not need to be retracted. When the handle 35 needs to be retracted, the handle 35 only needs to be retracted manually.

[0067] Through the above technical solution, the folding of the mobility scooter can be fully automatic, and the folding speed is fast. The various components cooperate well. Through the cooperation of various connecting rod structures, not only does it not require manual operation, but the folding of various parts can be carried out simultaneously, which is convenient and practical.

[0068] The arc frame 16 is provided with a decorative panel 55 covering the front wheel frame 10. The decorative panel 55 is set by the push rod 21 to the arc frame 16 on both sides. The decorative panel 55 does not affect the folding action of the push rod 21 and the arc frame 16. A net bag 56 is installed on the support frame 27. The net bag 56 is used to place the user's restricted items. The net bag 56 can be made of hard material, such as plastic, or soft material, such as nylon rope. The net bag 56 must not affect the folding of the rear wheel frame 11.

[0069] A battery pack 58 is installed in the decorative panels 55 on both sides of the push rod 21. The battery pack 58 is provided with a plurality of storage batteries. The storage batteries on the same side are a whole. The battery pack 58 is also equipped with a circuit controller 57 for cooperating with the handle 35 to control the output power of the drive motor 43 to control the running speed of the scooter.

[0070] A rotatable seat armrest 60 and a seat back 61 are provided on the top of the swing frame 31. A buckle limiter should be provided on the seat armrest 60 to prevent the seat armrest 60 from falling, so that the seat armrest 60 can only be rotated to the upper right to prevent interference when the mobility scooter is folded. At the same time, the flippable armrest also makes it convenient for users with physical disabilities to get on and off the vehicle. The damping setting of the seat back 61 can make the user more comfortable when driving the mobility scooter.

[0071] The frame is preferably made of aluminum, which can further reduce the weight of the vehicle and make it more convenient for users to use.

[0072] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
