[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.
[0031] In the embodiments of this application, please refer to Figure 1-3 As shown, this application provides a main wheel-integrated cockpit-type riding device, including: The inner support ring 3 is provided with a plurality of support rollers 4. For example, in this embodiment, three support rollers 4 are provided in an evenly distributed manner. The outer support ring 2 cooperates with the support roller 4 in a rolling manner and rotates around the inner support ring 3; The main wheel 1 is fitted on the outer support ring 2 and rotates synchronously with the outer support ring 2. That is, the outer support ring 2 is a wheel rim, and the main wheel 1 is fixedly engaged with the outer support ring 2. For example, it can be tensioned after assembly, integrally formed, or other methods. The main wheel 1 can be an inflatable tire, a solid tire, or it can be integrated with the outer support ring 2, that is, the two are the same component. The inner support ring 3 includes a seat tube 31, on which a seat pad 6 is provided. The seat pad 6 is fixed to the inner support tube 3 by fasteners, welding, or snap-fitting. The drive wheel 7 is connected to the inner support ring 3 and is in close contact with the outer support ring 7. It drives the outer support ring 2 to rotate through friction. Preferably, the drive wheel 7 is driven by a power source, such as a motor or engine. Alternatively, it can be driven by foot pedal. It also includes a front wheel control assembly 21, which is connected to the inner support ring 3 for auxiliary support and steering control.
[0032] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.
[0033] One way the drive wheels work: (Refer to...) Figure 4 The drive wheel 7 is directly driven by a hub motor, meaning that the drive wheel has its own hub motor and directly outputs power.
[0034] Another way the drive wheels work: See [reference] Figure 1 The drive wheel 7 is driven by a motor 11, which is fixedly mounted on the inner support ring 3 via a motor bracket 111. The output shaft of the motor 11 drives the drive wheel 7 to rotate via a transmission mechanism 10, which can be a chain drive, gear drive, belt drive, or other equivalent mechanism. The system also includes a battery pack 16 for providing power to the motor 11, which is mounted on the inner support ring 3 or the front wheel control assembly 21. Preferably, in this application, the transmission mechanism 10 is a chain drive, and the battery pack 16 is mounted on the inner support ring 3 near the front of the seat cushion 6.
[0035] Regarding the installation of the drive wheel 7: The drive wheel 7 is installed at one end of a drive wheel bracket 71, and the other end of the drive wheel bracket 71 is hinged to the inner support ring 3. A shock-absorbing spring 8 is provided between the inner support ring 3 and the drive wheel bracket 71.
[0036] In addition, depending on different design requirements, the motor 11 can also be installed on the front wheel control assembly 21, which still cooperates with the drive wheel 7 through the power transmission mechanism.
[0037] Preferably, the space between the seat post 31 and the outer support ring 2 is used to house the drive wheel 7 and the motor 11. The battery pack 16 can be installed on or inside the seat post 31. The seat post 31 is substantially parallel to the ground. Therefore, seating comfort can be ensured, and the resulting space helps to achieve a compact assembly of the structure.
[0038] In some embodiments, a drive wheel brake 9 is also provided on the drive wheel bracket 71 to bring the drive wheel to a stop. Optionally, the drive wheel brake 71 may be a cable brake (cable disc brake) or an electronic brake; those skilled in the art will understand its working principle and assembly relationship, which will not be elaborated here.
[0039] Regarding the front wheel control assembly 21, in this embodiment it specifically includes: a front wheel bracket 13, a front wheel fork 14, a front wheel 15, a seat tube, and a handlebar tube 19. The front wheel fork 14 is connected to the inner support ring 3 through the front wheel bracket 13. The front wheel 15 is mounted on the front wheel fork 14 to achieve rotation. The upper end of the front wheel fork 14 is provided with the seat tube and the handlebar tube 19. The handlebar tube 19 is provided with an accelerator handle 17 and a brake handle 18. The front wheel 15 is steered and the drive wheel 7 is accelerated and braked through the handlebar tube. The front wheel bracket 13 is also provided with a foot pedal 12 to facilitate foot placement during riding.
[0040] In addition, refer to Figure 5-8As shown, in the second embodiment of the dual-wheel implementation, the inner support ring 3, outer support ring 2, and main wheel 1 are symmetrically arranged in two sets. The two inner support rings 3 are connected by multiple support rods 32 to form an inner support frame. The seat cushion 6, front wheel control component 21, and drive wheel 7 are all mounted on the inner support frame. The drive wheel 7 can cooperate with one of the inner support rings 3 or with both inner support rings 3 simultaneously. This dual-wheel implementation is an improved version based on the aforementioned single-wheel embodiment. Provided that the solution can be implemented, some embodiments can refer to the solutions in the aforementioned single-wheel embodiment.
[0041] In addition, the support roller 4 is mounted on the inner support ring via a mounting base, and the mounting base is provided with a roller adjuster 5 for adjusting the friction between the roller and the outer support ring.
[0042] As one example, the roller adjuster 5 includes an adjusting screw and nut assembly for adjusting the relative position of the support roller on the mounting base. Specifically, the fitting clearance or friction between the support roller 4 and the outer support ring 2 can be adjusted by increasing or decreasing the number of nuts. There are many other ways to adjust the roller adjuster 5, which are not specifically limited here. Those skilled in the art can make adjustments based on the embodiments of this application, such as installing a spring and adjusting the spring compression; or changing the diameter of the support roller, etc.
[0043] Preferably, the inner support ring 3 comprises multiple straight tubes connected and enclosing each other at an angle, with the support roller 4 positioned at the bends where several of the straight tubes meet. This improves the connection strength and overall rigidity.
[0044] Regarding other installation methods for the battery pack 16: In addition to mounting the battery pack 16 on the seat tube 31 of the inner support ring 3 as shown in the above embodiment, there are several other methods, such as mounting the battery pack 16 inside the tube of the inner support ring 3, or mounting it at a certain position on the front wheel control assembly 21.
[0045] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
