Abstract

A compact, automatic balancing transportation device comprising a first foot platform section, a second foot platform section, a control circuit, and a coupling structure coupling the first foot platform section and the second foot platform section to each other such that the first foot platform section and the second foot platform section are angularly movable back and forth relative to each other; and a battery, wherein the coupling structure is configured to define a cavity to receive the battery. The left foot platform portion and the right foot platform portion are coupled for fore and aft pitch angle motion relative to each other. The left caster and the right caster are located below the respective foot pedals. If the rider's weight is directed primarily downward toward the wheel rather than toward the coupling structure, the coupling structure may have sufficient space to accommodate the battery. In addition, more efficient and lighter weight support and bearing arrangements may be used in the coupling structure.

Description

Compact automatic balance conveyer

Technical Field

The present invention relates to an automatic balancing transporter, and more particularly, to compact form and cost-effective manufacture in a hovering plate-type automatic balancing apparatus.

Background

The prior art includes several automatic balancing transfer devices. These include Solowheel, developed by Kamen et al and made by Chen (U.S. Pat. No. 8,807,250), and Hovertrax, also made by Chen (U.S. Pat. No. 8,738,278), in U.S. Pat. No. 6,302,230, among others. These three patents are incorporated by reference as if fully disclosed herein.

With respect to Hovertrax of the' 278 patent, this device has become popular. However, there is a need for an apparatus similar to that of the' 278 patent, but which is more compact and in which the components are more strategically arranged, particularly the battery, the wheels, and the support structure. There is also a need to reduce manufacturing costs as compared to prior art devices and manufacturing techniques.

Detailed Description

Referring to fig. 1, a perspective view of an automatic balancing transporter 10 according to the present invention is shown. The device 10 is similar to the automatic balancing device of the' 287 patent, for example, they are automatic balancing devices in which the rider stands forward.

The apparatus 10 may include two

motors

21, 31,

foot platforms

22, 32, two fore and aft tilt

angle position sensors

24, 34, such as gyroscope sensors, a control circuit 45 and a battery 48. The devices 10 are housed in

housing portions

51, 52, respectively, and are preferably coupled to each other by a coupling structure or "bridge" 50. This configuration provides sufficient platform spacing for the desired riding position, maintains the wheels in a parallel relationship, provides adequate structural support, and provides pitch-back movement of the two

platform sections

20, 30. A seam or gap 15 is visible where the two

housing parts

51, 52 meet externally.

Fig. 2 is a partial sectional view showing the mutual coupling of the left side case 51 and the right side case 52. The housing 52 has a sheath 54 which extends into a sheath recess 53 in the housing 51. The sheath is fixed. It is secured to the housing 51 by an annular projection 55 which fits into a complementary recess 56. The battery 48 is preferably disposed in a space (or cavity 49) within the sheath 54.

In conventional suspension plate embodiments (such as the embodiment of the' 278 patent), the wheels are located outside of the foot board. This results in the weight of the rider exerting a considerable force on the coupling structure. The present invention recognizes that by placing the wheel under the platform, the weight of the cyclist is no longer applied to the coupling structure (directly down on the wheel), thereby eliminating the need for larger bearings and support structures in the axle. Eliminating these components creates enough space in the coupling structure 50 to accommodate the battery 48, and then frees up space under the platform of the wheel (where the battery would traditionally be located). This achieves the desired more compact form.

In addition, the structural support of reducing the bearing size d can also reduce the manufacturing cost, the overall weight of the equipment, the transportation cost and the like.

The housing recess 53, the sheath 54, the protrusion 55 and the complementary recess 56 may be made of or coated with a low friction high wear resistant nylon or similar substance to allow for long term, low friction movement of the left and right foot platforms (and housing portions 51), 52) relative to each other.

Fig. 3 shows the device 10 of fig. 1 and 2 in a partial cross-sectional view. Referring to fig. 1-2, there is also an optional bearing arrangement 61. The bearing device 61 includes an extension 62 of the housing portion 51 that is extendedly mounted around the sheath 54 and is coupled in a recess 66 by a ball bearing 64. Extensions, ball bearings and recesses are provided annularly around the sheath 54. The design of the device 10 allows for the use of a lighter weight ball bearing device than prior art devices.

Fig. 4 and 5 show a second embodiment for coupling two platform parts. In the device 110, the housing portion 151 is longer than the housing portion 152 and terminates in a pair of bearing rings 171. These rings fit within complementary structures 172 (shown in cross-section) in the housing portion 152 to securely and rotatably couple the two housings. And (4) partial. There is sufficient space within the coupling structure 150 to accommodate the battery 148, but the coupling structure or bridge (in this or other embodiments) is still sized to be portable by hand.

Fig. 6 and 7 show a third embodiment for coupling two platform parts. The embodiment of fig. 1 to 3. Fig. 6-7 are similar to fig. 5 and 6. As shown in fig. 4-5, two bearing rings 271 are disposed on opposite sides of the cavity 249, rather than adjacent to each other on one side.

Fig. 8 shows a fourth embodiment of an automatic balancing device 310 according to the present invention. Device 310 is similar to device 210 of fig. 1 and 2. In fig. 6-7, one bearing ring 373 is smaller than the other bearing ring 371.

It can be seen in fig. 6 that bearing 271 has a larger cross-sectional dimension than cavity 249, while in fig. 8 bearing 371 has a larger cross-sectional dimension than cavity 349.

Although the invention has been described in connection with specific embodiments thereof, it will be understood that the invention is capable of further modifications and this application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention. Included within the scope of the present invention are known or customary practice in the art to which the invention pertains, and to which the basic features set forth above may be applied, within the scope and limitations of the present invention, including the differences with the present invention.
