Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and in particular to an automatically adjustable scooter. Background Art

[0002] Existing scooters usually have a brake assembly on the rear wheel assembly, which can be triggered by one foot to achieve a braking effect. This operation can be easily achieved when the buffer distance is long, but in complex road conditions, or when the user fails to notice in time, it is easy to fail to brake in time, causing the scooter to hit pedestrians or other objects, causing danger to both the user and the person being hit. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides an automatically adjustable scooter which can solve the problem that the scooter in the prior art is difficult to brake in time.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An automatic regulating scooter is provided, which comprises a pedal, the lower side of which is hinged to a mounting plate, and the mounting plate is transmission-connected to a wheel via a wheel axle;

[0006] The front end of the pedal is an arc-shaped plate, a buffer block is arranged on the lower side of the arc-shaped plate, and a distance sensor is arranged in the buffer block;

[0007] The mounting plate is provided with a housing, and a reduction motor connected to the wheel shaft transmission is provided inside the mounting plate; a controller and a power module connected to each other are installed on the mounting plate, and the reduction motor and the distance sensor are electrically connected to the controller and the power module respectively;

[0008] The mounting plate is symmetrically provided with a fixing seat, on which a limiting plate is installed, and the limiting plate is opposite to the wheel axle;

[0009] A lifting device is provided on the mounting plate, and the lifting device is hinged to the lower end of the pedal;

[0010] The wheel shaft is provided with a transmission gear matched with the reduction device and a transmission ring matched with the limiting piece.

[0011] The main beneficial effects of the automatic adjustable scooter provided by the present invention are:

[0012] The automatic adjustable scooter provided by the present invention reduces the damage caused by collision with people by arranging a buffer block, and monitors in real time whether there are obstacles or people in front of the scooter by arranging a distance sensor, thereby assisting the user to determine in time through a controller whether to slow down, so as to avoid colliding with people or obstacles and causing injuries to the user.

[0013] By setting a reduction motor, when the controller detects that deceleration is required, the reduction motor can be used to quickly reduce the speed of the scooter.

[0014] By setting the limit plate to contact the wheel axle, the wheel speed can be directly reduced by friction; when the limit plate is set to contact the wheel axle intermittently, the effect of the ABS anti-lock braking system can be achieved. The limit plate cooperates with the reduction motor to quickly reduce the vehicle speed.

[0015] By setting up a lifting device, the height of the rear side of the scooter is lowered while the speed is reduced, so as to move the user's center of gravity backwards, and avoid the user falling forward due to inertia when the speed is reduced, thereby effectively ensuring personal safety.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings:

[0022] like Figure 1 As shown, it is a structural schematic diagram of an automatic regulating scooter.

[0023] The automatic regulating scooter of the present invention comprises a pedal 1 , the lower side of which is hinged to a mounting plate 2 , and the mounting plate 2 is transmission-connected to a wheel 3 via a wheel axle 31 .

[0024] The front end of the pedal 1 is an arc-shaped plate 11 , a buffer block 12 is arranged at the lower side of the arc-shaped plate 11 , and a distance sensor 13 is arranged inside the buffer block 12 .

[0025] A housing 21 is provided on the mounting plate 2. Figure 2 As shown, the front end of the housing 21 is hinged to the lower end of the pedal 1 through the support rod 26, and a reduction motor 44 is arranged in the mounting plate 2 and is transmission-connected to the wheel shaft 31. The mounting plate 2 is mounted with a controller 23 and a power module 25 connected to each other, and the reduction motor 44 and the distance sensor 13 are electrically connected to the controller 23 and the power module 25, respectively.

[0026] The mounting plate 2 is symmetrically provided with a fixing seat 41 , on which a limiting plate 42 is installed, the limiting plate 42 is opposite to the wheel axle 31 ; the mounting plate 2 is provided with a lifting device 5 , which is hinged to the lower end of the pedal 1 .

[0027] The wheel shaft 31 is provided with a transmission gear 32 matched with the reduction motor 44 and a transmission ring 33 matched with the limit plate 42 .

[0028] Specifically, the pedal 1 is provided with a plurality of limiting holes 14 , which are located in the pedal area. An inflatable bag 15 is provided at the lower side of the pedal 1 , and an inflatable flange 16 matching with the limiting holes 14 is provided on the inflatable bag 15 .

[0029] An air pump 17 connected to the air bag 15 is provided at the lower side of the pedal 1. The air pump 17 is electrically connected to the power module 25 and the controller 23. Figure 3 shown.

[0030] The inflatable flange 16 is cylindrical, and the upper end of the inflatable flange 16 is hemispherical. The upper end of the inflatable flange 16 is a frosted surface.

[0031] By providing the inflatable bag 15 and the inflatable flange 16, when the scooter decelerates, the inflatable pump 17 starts to pump air into the inflatable bag 15, so that the inflatable flange 16 expands and passes through the limiting hole 14 to contact the foot. The frosted surface of the inflatable flange 16 increases the friction between the user's foot and the scooter, thereby preventing the user from slipping and causing accidental injuries when the scooter decelerates.

[0032] like Figure 4 As shown, the side of the transmission ring 33 is a plurality of planes connected in sequence. The limit piece 42 is a vertically arranged magnet sheet, and a connecting spring 43 is arranged between the fixing seat 41 and the limit piece 42. The limit piece 42 is electrically connected to the controller 23 and the power module 25. When the limit piece 42 needs to contact with the transmission ring 33 to reduce the rotation speed of the axle 31, the limit piece 42 is energized to make the limit piece 42 become an electromagnet and adsorbed with the transmission ring 33. When the power is stopped, it returns to its original position under the pulling force of the connecting spring 43.

[0033] Preferably, the controller 23 is connected to the timer 24. By setting the timer 24, intermittent adsorption between the limit plate 42 and the transmission ring 33 is achieved to prevent the wheel 3 from locking and slipping.

[0034] A reduction gear 45 is disposed at the output end of the reduction motor 44 , and the reduction gear 45 is meshedly connected with the transmission gear 32 .

[0035] The lifting device 5 comprises a rotating seat 51 arranged on the mounting plate 2 , on which an electric push rod 52 is arranged, and the output end of the electric push rod 52 is hinged to the bottom surface of the pedal 1 .

[0036] A laser sensor 53 is disposed on the side of the electric push rod 52, and the output end of the laser sensor 53 is in the same direction as the electric push rod 52. The electric push rod 52 and the laser sensor 53 cooperate to monitor the relative distance between the pedal 1 and the mounting plate 2, thereby adjusting the relative height of the rear side of the pedal 1, and then adjusting the center of gravity of the user to prevent falling.

[0037] The above describes the specific embodiments of the present invention to facilitate those skilled in the art to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations using the concept of the present invention are protected.
