Description

Technical Field

[0001] This utility model relates to the field of scooter technology, specifically to an anti-tipping scooter. Background Technology

[0002] Scooters are a type of transportation based on traditional human-powered skateboards, with the addition of electric components. Electric skateboards are generally divided into two-wheel drive or single-wheel drive, with the most common transmission methods being hub motors and belt drive. Their main power source is lithium battery packs. Electric scooters belong to the small-wheeled vehicle category and are characterized by high speed and long range. They consist of handlebars, wheels, pedals, etc., and are powered by batteries and driven by DC motors.

[0003] Existing scooters are mainly classified into two-wheeled scooters, three-wheeled scooters, and multi-wheeled scooters with four or more wheels for special purposes, based on the number of wheels mounted on their outer surface.

[0004] However, since the two-wheeled scooters only have two drive wheels, the front and rear wheels, they require a high degree of balance from the operator and are therefore quite dangerous. As a result, they do not meet the current needs. Therefore, we have proposed a scooter that is designed to prevent tipping over. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-tipping scooter to solve the problems mentioned in the background art, such as the high requirements for the operator's balance and the high overall risk due to the fact that the two-wheeled scooter only has two drive wheels, the front wheel and the rear wheel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-tipping scooter, comprising a scooter, wherein a stepper motor is fixedly installed on one side inside the scooter, the output shaft of the stepper motor is connected to a threaded rod via a coupling, an internal threaded sleeve is installed on one side of the outer surface of the threaded rod via a threaded structure, a toothed rack is fixed on the lower end face of the internal threaded sleeve and slidably connected to the scooter, a gear is engaged at the middle position of the lower end face of the toothed rack, an arc-shaped toothed rack is engaged on the lower end face of the gear, an arc-shaped bracket is fixed on the lower end face of the arc-shaped toothed rack and slidably connected to the scooter, and a roller mounting groove is provided on both sides of the outer surface of the arc-shaped bracket, and multiple protective support rollers are installed inside the two roller mounting grooves.

[0007] Preferably, a balance sensor is fixedly installed inside the scooter below the threaded rod, and the balance sensor is electrically connected to the stepper motor.

[0008] Preferably, the lower part of the arc-shaped bracket is provided with an arc-shaped groove located inside the scooter, and an arc-shaped anti-detachment rod is fixed inside the arc-shaped groove. An anti-detachment sleeve is movably fitted at the middle position of the outer surface of the arc-shaped anti-detachment rod, and the upper end face of the anti-detachment sleeve is fixed to the arc-shaped bracket.

[0009] Preferably, the gear shaft is connected to the axis of the gear, both ends of the gear shaft are located inside the scooter shell, and the gear shaft located inside the scooter shell is connected to the scooter via roller bearings.

[0010] Preferably, the arc-shaped bracket is arc-shaped in its entirety, and the arc-shaped bracket is made of high-strength metal in one piece.

[0011] Preferably, the rear end of the threaded rod is located inside the scooter shell, and the threaded rod located inside the scooter shell is connected to the scooter via a roller bearing.

[0012] Preferably, a protective cover plate is provided above the stepper motor on the outer surface of the scooter, and the scooter and the protective cover plate are fixed together by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features an arc-shaped bracket inside the scooter, with multiple protective support rollers mounted on its front and rear ends. A balance sensor located below the arc-shaped bracket monitors the scooter's tilt angle in real time. If the scooter tilts more than 45 degrees while the operator is riding it, a stepper motor electrically connected to the balance sensor will automatically start. This stepper motor pushes the arc-shaped bracket towards the side of the scooter tilting at an angle exceeding 45 degrees until the protective support rollers mounted on the outer surface of the arc-shaped bracket are in contact with the ground, thus supporting the entire device and preventing it from tipping over. This technical solution automatically supports the scooter when its tilt angle exceeds 45 degrees, thereby improving its safety. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The scooter 1 (model X1), stepper motor 3 (model DM542) and threaded rod 4 (model M08) mentioned in this utility model can be obtained from the market or through private customization.

[0022] Please see Figures 1 to 4 This utility model provides an embodiment of an anti-tipping scooter, comprising a scooter 1, a stepper motor 3 fixedly installed on one side inside the scooter 1, the output shaft of the stepper motor 3 connected to a threaded rod 4 via a coupling, an internal threaded sleeve 5 installed on one side of the outer surface of the threaded rod 4 via a threaded structure, a toothed rack 6 fixedly fixed to the lower end face of the internal threaded sleeve 5 and slidably connected to the scooter 1, a gear 7 meshing at the middle position of the lower end face of the toothed rack 6, an arc-shaped toothed rack 8 meshing at the lower end face of the gear 7, an arc-shaped bracket 9 fixedly fixed to the lower end face of the arc-shaped toothed rack 8 and slidably connected to the scooter 1, a roller mounting groove 10 provided on both sides of the outer surface of the arc-shaped bracket 9, and multiple protective support rollers 11 installed inside the two roller mounting grooves 10; a balance sensor 2 fixedly installed inside the scooter 1 is provided below the threaded rod 4, and the balance sensor 2 is electrically connected to the stepper motor 3; the balance sensor 2 installed inside the scooter 1 can monitor the tilt angle of the scooter 1 in real time;

[0023] If the tilt angle of the scooter 1 on both sides exceeds 45 degrees while the operator is driving the scooter 1, the stepper motor 3, which is electrically connected to the balance sensor 2, will start automatically. The stepper motor 3 can drive the threaded rod 4 connected to it to rotate. Since the inner threaded sleeve 5, which is installed on the outer surface of the threaded rod 4 through the threaded structure, is fixed to the toothed rack 6, the inner threaded sleeve 5 cannot rotate on its own.

[0024] When the threaded rod 4 rotates, the internal threaded sleeve 5, which is threadedly connected to it but cannot rotate on its own, will move under the drive of the threaded structure. During the movement of the internal threaded sleeve 5, the toothed rack 6 fixed to it will move along with it. The moving toothed rack 6 can drive the gear 7 meshing with it to rotate. When the gear 7 rotates, the arc-shaped toothed rack 8 meshing with its lower end face will move along with it. During the movement of the arc-shaped toothed rack 8, the arc-shaped bracket 9 fixed to it will move along with it. At this time, the arc-shaped bracket 9 is pushed towards the surface of the scooter 1 with an inclination angle of more than 45 degrees until the protective support roller 11 inside the roller mounting groove 10 installed on the outer surface of the arc-shaped bracket 9 is in contact with the ground, thereby supporting the entire equipment. Through the above technical solution, when the inclination angle of the scooter 1 exceeds 45 degrees, it can automatically support it to prevent it from tipping over, thereby improving the overall safety of the equipment.

[0025] When the tilt angle of the scooter 1 on both sides is less than 45 degrees, the stepper motor 3 will drive the arc-shaped support 9 back to its original position.

[0026] Below the arc-shaped bracket 9 is an arc-shaped groove 12 located inside the scooter 1. An arc-shaped anti-detachment rod 13 is fixed inside the arc-shaped groove 12. An anti-detachment sleeve 14 is movably fitted on the middle position of the outer surface of the arc-shaped anti-detachment rod 13, and the upper end face of the anti-detachment sleeve 14 is fixed to the arc-shaped bracket 9. The anti-detachment sleeve 14, which is fixed to the outer surface of the arc-shaped bracket 9 and movably fitted on the outer surface of the arc-shaped anti-detachment rod 13, can prevent the arc-shaped bracket 9 from falling off.

[0027] The shaft of gear 7 is connected to gear shaft 15. Both ends of gear shaft 15 are located inside the shell of scooter 1, and gear shaft 15 located inside the shell of scooter 1 is connected to scooter 1 by roller bearings. Gear 7 can be positioned in its current position by gear shaft 15, thereby improving its stability.

[0028] The arc-shaped bracket 9 is arc-shaped as a whole and is made of high-strength metal in one piece. By using high-strength metal to make the arc-shaped bracket 9, it is possible to prevent the arc-shaped bracket 9 from bending due to the impact force when the protective support roller 11 installed on the outer surface of the arc-shaped bracket 9 comes into contact with the ground.

[0029] The rear end of the threaded rod 4 is located inside the shell of the scooter 1, and the threaded rod 4 located inside the shell of the scooter 1 is connected to the scooter 1 by a roller bearing; the roller bearing structure between the threaded rod 4 and the scooter 1 can improve the overall stability of the threaded rod 4.

[0030] A protective cover plate is provided above the stepper motor 3 on the outer surface of the scooter 1, and the scooter 1 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the stepper motor 3.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
