Abstract
The utility model relates to a bicycle trailer, particularly a trailer which can put the trailer body on the bicycle after folded. The utility model comprises a trailer body and a steering device. The trailer body is composed of two symmetrical side support stands and a cross support stand connected with the two side support stands, each of the supporting rod which forms the lower part of the side support stand is connected with wheels, the steering device is composed of towbars and a steering mechanism connected between the towbars and the trailer body, and the cross support stand is composed of a collapsible four-link mechanism.
Description
The utility model relates to a kind of trailer of bicycle, specifically a kind of trailer that car body can be folded on the bicycle.
The trailer of bicycle is many, have to attach, but this class trailer all can not be in temporary transient time spent not at trailer of bicycle side or back etc., with the trailer folding on bicycle.Thereby it is cumbersome.
The purpose of this utility model is a kind of foldable trailers of design, to overcome above-mentioned defective.
Its main technical schemes comprises car body and steering hardware, car body is made up of two side stands of symmetry and the transverse bracket that connects two side stands, the cramp bar that constitutes the side stand bottom is connected with wheel, steering hardware by drawbar and be connected car body and drawbar between steering hardware form, transverse bracket is a folding four-bar linkage, wherein the two ends of upper and lower connecting rod are hinged on respectively in U type bar and the grooved joint, and the part between the hinge-point of upper and lower connecting rod and U type bar and grooved joint constitutes two connecting rods in addition of four connecting rods; Open joint in the steering hardware with connect deflecting bar with the bearing pin that can in open joint, rotate again after drawbar is connected, the other end of deflecting bar is arranged in the hole at U type bar middle part rotationally; Connecting portion at drawbar and open joint has a latch, unclamp latch, drawbar and open joint are rotated mutually, locating dowel pin is arranged on connecting rod, corresponding site at the grooved joint is jagged, and the other end of drawbar can be hinged with the hind axle of bicycle, and in this hinge point a fastener is installed, utilize this fastener after car body being folded on the bicycle schoolbag frame, can fix the position between drawbar and bicycle rear.
Advantage of the present utility model is that the car body transverse bracket is made up of four-bar linkage, in use, four-bar linkage can be strutted, the boxed rod that makes transverse bracket constitutes work top with the cross bar of side stand, plug latch on the drawbar and the locating dowel pin on the boxed rod, four-bar linkage is horizontal substantially, when not needing to use, pull out latch, lift trailer body, U type bar is rested on the schoolbag frame, four-bar linkage and side stand are hung on the trailing wheel both sides, block with fastener again, drawbar is fixed on the bicycle schoolbag frame, thereby dwindled the transverse width of trailer.Secondly, owing between drawbar and car body rotating mechanism is set, when the rider get on and off and the process of riding in bicycle body when producing lateral rotation, the side that can not cause trailer body is changeed, perhaps when trailer two-wheeled during at the rugged road scend of side direction ripple, can not drive bicycle and make side direction top ripple together, the setting of bearing pin makes can have mutually between bicycle quick and trailer and horizontally rotates, so that when turning voluntarily, can drive trailer and turn together.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is for removing the right elevation behind bicycle rear and the fastener among Fig. 1.
Fig. 3 is a folded state diagram.
Fig. 4 has removed the left view behind the bicycle among Fig. 3.
As shown in the figure: an end of drawbar (13) and open joint (11) are hinged, the other end is hinged on the bicycle rear shaft (20), coupling end at drawbar and open joint has latch (19), when trailer body drags in the bicycle back, this latch can be inserted in the hole on the open joint, make between drawbar (13) and open joint (11) and can not relatively move, fastener (14) is installed on hind axle (20), when trailer body is in folding state, can utilize the locking of this fastener and drawbar, in order to avoid car body slides from bicycle.
Open joint (11) also utilizes rotating bearing pin (12) to connect deflecting bar (10), but make the car body relative proper motion car that is connected the deflecting bar other end do the rotation of horizontal direction, the other end of deflecting bar is arranged in the U type bar (8) rotationally, car body can be rotated in vertical direction relative to deflecting bar, the two ends of U type bar hinged respectively two folding on, lower link (7), (6), the other end of upper and lower strut is hinged in the grooved joint (5), one breach is arranged on the grooved joint, locating dowel pin (16) is arranged on the boxed rod (7), utilize this locating dowel pin and breach to make, lower link is when open configuration, remain on basic horizontal and the position, so that the tranverse connecting rod (9) on boxed rod (7) and the side stand constitutes work top.Upper and lower connecting rod and U type bar constitute transverse bracket, other two connecting rods that go up, the part between the point of connection of connecting rod and U type bar and grooved joint constitute four-bar linkage.
Side stand is made of tranverse connecting rod (9), grooved joint (5), cramp bar (3), and axletree (1) and wheel (2) are installed on cramp bar (3), and cramp bar is captiveed joint with grooved connector by using bolt (4).
Among the figure, (15) are bicycle rear, and (17) are bicycle bag rack, (18) be bicycle saddle cushion.
