Abstract
This design incorporates four separate modules which are bolted together in this succession: a welded, structural single-unit steering tube/downtube module; independent, twin, front-to-rear horizontal frame rails which serve as the support for the rider to stand; a welded, structural single-unit module to mount shock absorbers and a swingarm; and, a welded swingarm. The defined space between the twin frame rails and the two adjoining modules can be modified by altering the length of the frame rails and/or using spacers between each rail and its corresponding module at the bolt-on location.
Claims
1. An electric kick-scooter comprising: a first module including a steering tube and a downtube, the steering tube being welded to the downtube forming a single-unit; a second module including two front-to-rear horizontal frame rails, the second module being an independent structure from the electric kick-scooter and the two front-to-rear horizontal frame rails being parallel twins, wherein the first module is connected to the second module via one or more bolts; a third module including a shock absorber mount and a swingarm mount, the shock absorber mount being welded to the swingarm mount forming a single-unit, wherein the third module is connected to the second module via one or more bolts and at least two shock absorbers are bolted to the shock absorber mount; and a fourth module including a swingarm, wherein the fourth module is connected to the third module via one or more bolts, wherein the second module is adapted to receive a battery of differing size or shape, and wherein the first module, the second module, the third module and the fourth module are bolted together in succession.
2. The electric kick-scooter frame structure according to claim 1, the electric kick-scooter further comprising a first set of spacers provided between the first module and the second module, the first set of spacers being disposed such that the one or more bolts pass through the first set of spacers, and a second set of spacers provided between the second module and the third module, the second set of spacers being disposed such that the one or more bolts pass through the second set of spacers.
3. The electric kick-scooter frame structure according to claim 1, further comprising: an electric hub motor connected to the fourth module.
Description
BRIEF DESCRIPTION OF THE DRAWINGS
(1) FIGS. 1A, 1B, 2, 3, 4A and 4B each show conventional kick-scooters.
(2) FIG. 5 shows a kick-scooter complete and ready-to-ride, according to an example embodiment herein.
(3) FIG. 6 shows a view of the kick-scooter with ancillaries and components removed for clarity of frame structure.
(4) FIG. 7 shows four modules of a kick-scooter in an exploded view, according to an example embodiment.
(5) FIG. 8 shows the four modules in an exploded view canted side angle.
(6) FIG. 9 shows the four modules viewed in a canted angle with paths of bolts.
(7) FIG. 10 shows an aftermarket, longer than original frame rail.
(8) FIG. 11 shows the four modules with an exploded rear angle view with rail spacers.
(9) FIG. 12 is a representative view of the four modules according to an example embodiment.
DETAILED DESCRIPTION
(10) FIG. 5 shows a kick-scooter fully assembled, completed with all necessary components to ride the vehicle. In an example embodiment, 26 mountain bike sized wheel assemblies are utilized which makes the vehicle suitable for adult riders.
(11) FIG. 6 is an exploded view of FIG. 5 but with many of the components removed to show the actual frame structure more precisely. The wheel assemblies (7,9) are not limited to standard 26 mountain bike sized wheels. The electric hub motor (10) is a product that comes in many output capacities and is not limited to any. The greatest benefit of this disclosure is the four modules: the steering tube (5) is connected to the downtube (6) and makes up a first module 1 in the succession of the four modules. A second module (2) or frame rails module, as shown in FIG. 6, is the left side rail. The second module (2) also includes a right side rail (hidden in the view shown in FIG. 6) being parallel and a twin to the left side rail. The second module (2) is the designated space for the battery (21) depicted in FIG. 5. This module can be changed with similar rails of the same bolting pattern but of different length and heights. Batteries for electric motors are continually changing and improving with updated technology. As there is no specific standardized sizes, an aftermarket battery could prove to be impossible to mount within the designated space. Having the ability to change only this module, with the three other modules remaining, the benefits of the updated technology may translate into shorter charging time, longer distances for travel between recharging and greater power output. A third module (3), the shock absorber and swingarm mount (3a and 3b respectively, shown in FIG. 7), is partially hidden in this view. A fourth module (4) or swingarm is partially hidden in this view.
(12) FIG. 7 is a partially exploded view of the four modules (1,2,3,4) in a line.
(13) FIG. 8 is an overhead view to show off the twin frame rails of module 2. The bolt paths (22) are shown in FIG. 9 to show how all four modules are joined. Exposed in FIG. 10 is an original equipment frame rail module (2) and the aftermarket, longer version of the rail (11). Length is limited only to a reasonably sized battery considering weight and overall dimensions. FIG. 11 shows an exploded view of the four modules with widening spacers (12) in between the frame rails and their corresponding bolt on positions to the modules (1,3).
(14) FIG. 12 shows a side view of a the four modules (1,2,3,4) constructed together.
