Abstract

The invention discloses an electric traveling case which comprises a case body and a pull rod arranged on the case body; the case body is provided with a wheel assembly; the case body is internally also provided with a motor and a power supply providing power for the motor; the power supply is connected with a control switch arranged on the case body; the wheel assembly comprises an output shaft and a reduction gearbox; both ends of the output shaft are each provided with a bearing; the bearings are connected with wheels; the reduction gearbox comprises a shell body; the shell body is provided with a universal wheel hollow rivet; the shell body is internally provided with a worm and a worm wheel; the worm is provided with a center hole; a drive shaft of the motor passes through the universal hollow rivet and the center hole and then is connected to the shell body; the worm is in matched connection with the worm wheel; the output shaft passes through the worm wheel, and then both ends of the output shaft extend out of the reduction gearbox. The motor driving is adopted as a propelling force of the case, the people own force application is reduced, walking is effortless, and people are easy to travel; the worm wheel and the worm are combined and the worm is larger than the worm gear, so the deceleration effect is good; and with adopting of the one-way bearings, the wheels cannot be clamped by the worm wheel in the reduction gearbox.

Description

A kind of electric travelling case

Technical field

The present invention relates to suitcase, be specifically related to a kind of electric travelling case。

Background technology

Existing suitcase is primarily present problems with and shortcoming: chest, when bearing a heavy burden, is that the strength by hands pulls, walking effort。

Summary of the invention

The present invention is directed to the problems referred to above, it is provided that a kind of electric travelling case, adopt manually and electric integral, when being not powered on, it is possible to pull by hands self strength；During energising, can adopting electronic, it is only necessary to direction held by hand steered pull bar, the present invention in use can reduce the load-carrying burden of people, travels particularly convenient for women, old man and children outside。

For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: a kind of electric travelling case, it is provided with pull bar including casing and casing, described casing is provided with wheel assembly, being additionally provided with motor in described casing and provide the power supply of power for described motor, power supply is connected at the control switch on casing。

Wheel assembly includes output shaft, reduction box, the two ends of output shaft are equipped with bearing, bearing connects wheel, reduction box includes housing, housing is provided with universal wheel tubular rivet, universal wheel tubular rivet connects thrust bearing, universal wheel tubular rivet connects casing, worm screw, worm gear it is provided with in housing, worm screw is provided with centre bore, the driving axle of motor is connected to housing through universal wheel tubular rivet and centre bore, and worm and wheel coupling connects, and output shaft extend out to outside reduction box through the two ends of worm gear rear output shaft。

Wherein, reduction box is placed in the outside of casing and is bonded wheel assembly with wheel, is effectively reduced the conversion of gear, improves efficiency。

Bearing is unilateral bearing, adopts unilateral bearing as the clutch system of wheel, and the worm gear institute that while transmitting as power, wheel will not be decelerated in case is seizing。

Wherein, worm gear is meshed with worm screw place, and the diameter of worm screw is more than the thickness of worm gear, employing worm and wheel combines, and amplitude peak can reduce gear change, and worm screw is more than the mode of worm gear, slowing effect is good, can slow down at short notice 20 times, simultaneously can the backward-substitition 90 degree of input and output。

Housing includes left shell, right shell body, left shell and right shell body and adopts and be screwed connection, it is simple to dismounting, install, and changes with easy to maintenance。

Control switch and can be located at the optional position of casing, it is preferable that be arranged on pull bar, when pulling pull bar, power supply state easy switching。

Wherein, power supply is accumulator。

The invention has the beneficial effects as follows: the present invention adopts motor to drive the boosting power as chest, alleviate self exerting oneself of people, leicht fallen D/A of walking, easily go on a journey；Adopting worm gear to be combined with worm screw and worm screw is more than worm gear, slowing effect is good, employing unilateral bearing, wheel will not worm gear in reduction box seizing。

Detailed description of the invention

Below in conjunction with embodiment, the specific embodiment of the present invention is further described。

As shown in Figure 1 to Figure 3, a kind of electric travelling case, it is provided with pull bar including casing and casing, described casing is provided with wheel assembly, it is additionally provided with motor in described casing and the power supply of power is provided for described motor, the driving axle traverse casing of motor, power supply is placed in the optional position in casing, preferably power supply is mounted to the bottom in casing, power supply is connected at the control switch on casing, control switch and can be located at the optional position of casing, it is preferably mounted on pull bar, when pulling pull bar, control switch can be started at any time according to individual's oneself state, more convenient compared to other position, wheel assembly includes output shaft 10, reduction box, the two ends of output shaft 10 are equipped with unilateral bearing 2, unilateral bearing 2 connects wheel 1, reduction box includes housing, housing is provided with universal wheel tubular rivet 6, universal wheel tubular rivet 6 connects thrust bearing 7, universal wheel tubular rivet 6 connects casing, worm screw 8 it is provided with in housing, worm gear 9, worm screw 8 is provided with centre bore, the driving axle 5 of motor is connected to housing through universal wheel tubular rivet 6 and centre bore, worm screw 8 is connected with worm gear 9 coupling, output shaft 10 extend out to outside reduction box through the two ends of worm gear rear output shaft, reduction box is placed in the outside of casing and is bonded wheel assembly with wheel, it is effectively reduced the conversion of gear, improve efficiency。

Wherein, housing includes left shell 4, right shell body 3, and left shell and right shell body are adopted and be screwed connection, it is simple to dismounting, installation, changes with easy to maintenance。

The present invention drives the boosting power as chest using motor, alleviates self exerting oneself of people, leicht fallen D/A of walking, easily goes on a journey。Additionally, for child's chest, after imparting chest is electric-powered, except alleviating child self and exerting oneself, it is also possible to header and object for appreciation are happy to integrally, and namely chest can fill thing, it is also possible to as electronic toy amusement。
