DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] like Figure 1-6 As shown, a protective travel vehicle is proposed in this embodiment, such as Figure 1 As shown, the vehicle comprises a handlebar 1, a front wheel 4, a rear wheel 5 and a mounting platform 18 for mounting a seat 3 and a frame 2. Two protection wheels 7 are respectively mounted on both sides of the mounting platform 18. The height of the two protection wheels 7 is higher than that of the seat 3 and the handlebar 1, forming a closed driving space therebetween. The protection wheels 7 comprise an inner ring 8 and an outer ring 9. A plurality of balls 10 are arranged between the inner ring 8 and the outer ring 9, forming a bearing structure.

[0026] In one specific embodiment 1: Figure 2-6 As shown, a support rod 6 is also provided at the lower end of the frame 2, and the length of the support rod 6 extends along the travel direction of the front wheel 4. Two protection wheels 7 are respectively installed at both ends of the support rod 6, and the inner ring 8 is fixed to the support rod 6 by a fixing rod 11.

[0027] Specifically, the number of the front wheels 4 is one or two, and the number of the rear wheels 5 can also be one or two, depending on the specific situation, which is not specifically limited in this article. The front wheels 4 are steering wheels, which have a steering function and can also prevent the vehicle from flipping forward. Since the front wheels 4 have a supporting function, the center of gravity of the vehicle is set forward, and all devices and drivers are placed in the front of the vehicle as much as possible to prevent the entire vehicle from flipping forward and backward and the driver and passengers from flipping inside when braking.

[0028] Furthermore, a tire 13 is mounted on the outer ring 9 of the protection wheel 7 .

[0029] Thus, by installing two protection wheels 7 on both sides of the mounting platform, the height of the two protection wheels 7 is higher than the seat 3 and the handlebar 1, and a closed driving space is formed between them. The rider is protected and the safety performance of the vehicle is improved. The protection wheel 7 includes an inner ring 8 and an outer ring 9, and a plurality of balls 10 are arranged between the inner ring 8 and the outer ring 9 to form a bearing structure. While providing protection, it does not affect the outer ring 9 rotating with the wheel, and at the same time provides support for riding, ensuring the stability of riding.

[0030] Furthermore, the protective travel vehicle in this embodiment also includes an anti-collision plate 16 (not shown in the figure) covering the outer periphery and top of the protective wheel 7. In order to facilitate the rider to observe the external situation at any time, the anti-collision plate 16 is made of transparent material. In this way, the driver and passengers drive in a closed space, which greatly improves the driving safety while ensuring that the vehicle body is small and has strong passability; even if the vehicle overturns, the rider is in the internal closed space surrounded by the anti-collision plates on the four sides and the top, and will not be damaged by external impact; and in encountering bad weather, such as rain, wind, winter, etc., the rider can be protected and travel is convenient.

[0031] Among them, Figure 5 As shown, in order to facilitate observation of external conditions, the anti-collision plate 16 at the hollow position of each protective wheel 7 can be set to a foldable structure, such as a folding fan structure, which can be unfolded when needed; if there is a strong wind, it can be folded up to reduce side winds.

[0032] Furthermore, a connecting rod 12 is fixed between the two inner rings 8 of the two protection wheels 7 to increase the connection stability of the two protection wheels 7. The support rod 6 and the inner ring 8, and the connecting rod 12 and the inner ring 8 are all welded and fixed.

[0033] Furthermore, the rear wheel 5 is connected to the fixing rod 11 through a fixing member 14, and the fixing member 14 is provided with a groove 15 for mounting the rear wheel 5, and the groove 15 adopts an inclined structure with a lower front and a higher rear. While being able to prevent the car from flipping backwards, the driving wheel (front wheel 4) will not slip due to the force on the rear wheel 5 (generally, due to the gravity of the rear wheel 5 itself, the rear wheel 5 will contact the ground but will not be subjected to force, so that it can be ensured that the front wheel 4 and the left and right tires 13 will not be subjected to force due to the force on the rear wheel 5; only when the car flips backwards due to the rear being heavier or other reasons, the gravity is transmitted to the rear wheel 5, causing the rear wheel 5 to be subjected to force, thereby preventing the car from flipping backwards).

[0034] Preferably, if Figure 1 As shown, in order to enhance the safety of the vehicle, an anti-collision ring 20 is connected to the inner ring 8 of the protection wheel 7. The upper and lower parts of the anti-collision ring 20 are connected by shock-absorbing materials 17, and the front and rear parts are connected by flexible anti-collision materials 18. This ensures the comfort of the vehicle while also increasing the safety performance of the vehicle.

[0035] Preferably, a closed whole is formed between the two protection wheels 7, wherein the mounting platform can be set as a metal plate, and the seats of the driver and passengers, the drive device, etc. are all built on this metal plate platform. Furthermore, a shock absorbing structure 21 is provided between the mounting platform 19 and the inner ring 8, and is located below the closed whole. Specifically, the shock absorbing structure can be installed on both the left and right sides, and the shock absorbing structure can be a spring or hydraulic shock absorbing structure, etc.

[0036] It should be noted that the closed whole formed by the two protective wheels 7 in this embodiment and the platform formed by connecting the shock-absorbing structure with the metal plate is the main structure. The frame 2, seat 3, front wheel 4, rear wheel 5 and other structures of the vehicle are all installed on this structure. The specific installation form depends on the actual design.

[0037] In summary, the protective travel vehicle in this embodiment is a means of transportation with strong passability, all-weather usability and high safety, which can facilitate people's travel while reducing casualties in traffic accidents.

[0038] It should be noted that the driving mode of the protective travel vehicle in this embodiment can be electric or human, etc., and the specifics can be referred to the prior art, and will not be repeated in this article. Specifically, the driving wheel can be the front wheel 4 or the protective wheel 7.

[0039] It should be noted that the front wheel 4 and the rear wheel 5 may also be equipped with a shock absorbing structure respectively.
