Description
Technical field
The utility model relates to consumer goods industries, and a kind of crawler belt can folding type electric luggage case specifically.
Background technology
At present, extensively by the bottom of luggage case that everybody uses, two rollers or four universal wheels are generally housed, during Land leveling, people can drag or carry out, but just can only carry when going upstairs or run into ground relief, makes troubles to trip.And the existing luggage case utilizing crawler belt to climb building has following several large shortcoming: 1. crawler belt is fixed on the crawler belt not used time wasting space of formula at the bottom of case, inconvenience storage; 2. crawler belt detachable luggage case crawler belt disassembling operations trouble, unhygienic; 3. Caterpillar belt span is not enough, can jolt during stair climbing; 4. pull bar ground proximity when going upstairs, is inconvenient to control; 5. drag luggage case stair climbing by manpower, not only effort but also incorrect also can the generation of force direction are jolted.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the utility model provide a kind of crawler belt deployable with withdrawal, longitudinally and horizontal two-stage pull bar combine and lean on driven by power crawler belt to climb the luggage case in building.
The utility model solves the technical scheme that its technical problem adopts: a kind of crawler belt can folding type electric luggage case.It is made up of rod assembly, crawler belt development mechanism, crawler unit, electric-control system, roller and casing.Pull bar is positioned at above casing; Back is furnished with three square grooves, one upper two under; Crawler unit is fixed by axle and connecting rod in square groove, can be controlled by crawler belt expanding unit; Four rolling is positioned at bottom half.Crawler unit is made up of crawler belt, Athey wheel, Athey wheel frame linking, has three crawler belts, one front, two rear.Crawler belt development mechanism is primarily of through some connecting rods composition on the axle of casing and axle, the connecting rod of crawler belt and development mechanism forms parallel-crank mechanism, the torsion of axle drives connecting rod swing, parallel-crank mechanism is made to realize the expansion of lifting and crawler belt, the gear be meshed for a pair make the corner of two active rotating shafts identical turn to contrary, like this, the drive connecting rod of rear two crawler belts and the drive connecting rod of last bar swing to both direction, thus three crawler belts are launched along both direction, realize reaching three grades of length of bench when crawler belt launches with this, the object of casing length is shorter than during withdrawal.Crawler belt can be placed in the groove of casing when regaining completely, does not account for redundant space.Control handle is arranged on a shaft, and handle can be stuck on two grooves that casing is arranged, and corresponding crawler belt is packed up and launched two positions, and the position of crawler belt is by locked on the draw-in groove that handle is stuck in casing.Rod assembly is fixed on casing, and to be nested together the pull realized along casing and the both direction perpendicular to casing by three parts, the control making people climb building to luggage case is more convenient.Electric-control system is made up of DC speed-reducing, chain-drive mechanism and main shaft, and motor, by lithium battery power supply, opens and closes by switch control rule, and the output of motor passes to track drive main shaft by chain-drive mechanism, drives latter two crawler belt, realizes electric stair climbing.
The beneficial effects of the utility model are, luggage case can be made not rely on or rely on manpower to climb building reposefully less, being convenient to storage simultaneously, simple to operate, both artistic and practical.

Detailed description of the invention
As shown in the figure, crawler belt can be made up of rod assembly 1, casing 2, crawler unit 3, roller 4, electric-control system 5 and crawler belt development mechanism 6 by folding type electric stair climbing luggage case.Pull bar is positioned at above casing; Back is furnished with three square grooves, one upper two under; Crawler unit is fixed by axle and connecting rod in square groove, can be controlled by crawler belt expanding unit; Four rolling is positioned at bottom half.
As Fig. 2, rod assembly 1 point of three part: Part I 101 is two hollow aluminum bars being fixed on casing; Two hollow aluminum bars of Part II 102 are enclosed within Part I, and they are in " L " type, and be folded to perpendicular to casing direction by along casing direction, two bars are connected by handle in bending place, and this hand control pull bar is along the pull in casing direction; Part III 103 is enclosed within Part II, by the pull of hand control perpendicular to casing direction.
As Fig. 3, crawler unit is made up of crawler belt 301, Athey wheel 302, Athey wheel frame linking 303.Crawler belt both sides are supported by two connecting rods 606 respectively, form parallel-crank mechanism with crawler belt development mechanism.
As Fig. 6, crawler belt development mechanism is made up of control handle 601, major axis 602, axis 603, three minor axises 604, pair of engaged gears 605 and some support link 606.As Fig. 4, crawler belt control handle 601 is arranged on major axis 602, and handle can be stuck in (correspondence is packed up and launched two positions) in two grooves on casing.Part on major axis and axle are connected (the axle a bit of distance that can slide axially does not affect other part positions on axle, but part circumference can be made to rotate) by feather key.Expansion process is as follows: extracted (long axis axially outwards slides simultaneously) from draw-in groove by handle, then swing handle makes major axis 602 rotate, the connecting rod 606 be connected with major axis is as driving lever, drive parallel-crank mechanism to launch (the connecting rod synchronous hunting on minor axis), rear two crawler belts achieve expansion like this.Meanwhile, axis 603 passed to by the gear 605 be meshed for a pair that rotates through of major axis 602, and their corner is identical to be turned on the contrary, so the connecting rod on axis drives previous crawler belt to launch along other direction as driving lever.Article three, after crawler belt opens up assigned address simultaneously, handle is pressed into another draw-in groove on casing, crawler belt is just fixed on this position.It is contrary that crawler belt regains process, and after regaining, crawler belt can be placed in the groove of casing completely.
Electric-control system 5 is made up of chain-drive mechanism 501, DC speed-reducing 502, track drive axle 503, and motor, by DC power supply, opens and closes by switch control rule, and switch is located on afterbody pull bar 103 handle, and electric wire passes from pull bar.The output of motor is passed on track drive axle 503 by chain-drive mechanism 501, and driving shaft drives the last belt wheel of latter two crawler belt to rotate (the unpowered input of last bar crawler belt).As Fig. 7, with the expansion of development mechanism, motor output shaft synchronously rotates (line is parallel with support link) around electric machine main shaft with the line of track drive axle.
