Abstract

The utility model discloses a multifunctional tail rack for a motorbike, which comprises frames and reinforcing beams. The frame comprises metal bars or elbow bends which are all assembled together. The tail section of the rack is semicircular or square. The rack is divided into a front rack and a rear rack. Reinforcing beams are installed between different frames. The rear rack is a three-layered frame structure, and each layer thereof is same in size and shape and is overlapped with two others, namely an upper frame, a middle frame and a lower frame. Two symmetrical upturning rectangular frames are equipped at two sides of the front rack via a double-way spring supporting hinge. In addition, tail ends of two metal bars or pipes extending in parallel are bent into round-arc shaped fixing connectors to be connected with a rear shock-absorber in a fixed way. The utility model provides a multifunctional tail rack, which is provided with a simple structure, a proper design and complete functions and which integrates functions of acting as a backrest, a rear armrest and a tail goods rack to enlarge loading space. Thus, the tail rack is provided with strong practicability.

Description

The multi-functional tail product frame of motor bike

Technical field the utility model relates to a kind of Real luggage carrier for motorcycle, the multi-functional tail product frame of particularly a kind of motor bike.

Products such as the existing motor bike tail product of background technology frame, backrest cushion, back bar are a feast for the eyes, multifarious, but mostly separately at a certain specific function and design-calculated, thereby the property taken into account between each function of the said goods just seems not enough, even cause conflict and repellence between each function, as backrest cushion or back bar be installed, just if again with the car lade insufficient space that seems; Strengthen between the arrival of looking back mutually is built on stilts, it is not enough that the traveling comfort of rear rider and safety are felt again.Such as, certain novel product---the following rollover tail product frame of motor bike that occurs on the present market, in use, its outer Zhang Kuandu has exceeded existing national communication rules, must not exceed the regulation of handlebar width to the motor bike lade, certainly will have certain potential safety hazard during this violation rollover shelf travel.

The summary of the invention the purpose of this utility model is the insufficiency of function that exists for the products such as tail product frame, backrest cushion and back bar that overcome existing motor bike, in conforming with the scope of traffic law, provide a kind of double very strong multi-functional tail product frame of motor bike of practicality of doing back bar and tail product frame expansion loading space of backrest cushion that integrates.

The multi-functional tail product frame of motor bike of the present utility model is achieved by following technical proposals: the utility model comprises framework and frame strengthening beam, described framework is to be bent by bonding jumper or pipe to combine, afterbody semicircular in shape or square, shelf and back shelf before dividing, be equipped with reinforcement in the middle of each framework, back shelf are three layers of identical with shape and overlapping frame structure that is installed together of size, it is the upper strata framework, middle level framework and lower floor's framework, before shelf both sides frames by the bidirectional spring supporting hinges upper-turn-type rectangular frame of two symmetries is housed, two bonding jumpers that extend in parallel forward in addition or the tail end of pipe bend to the circular arc fixed connector and captive joint with rear shock absorber of motorcycle.

The multi-functional tail product frame of motor bike of the present utility model compared with prior art, its beneficial effect is:

1. the upper-turn-type rectangular frame of two symmetries of shelf can enlarge payload area after launching before the utility model.

2. the upper strata framework of shelf also is provided with the framework of two and half fan-shaped symmetries behind the utility model, and its first half is provided with backrest cushion, and the frame that lower part exposes can be made back bar usefulness, and the framework of two and half fan-shaped symmetries also can enlarge payload area after launching.

3. the utility model adopts the bidirectional spring supporting hinges of energy self-orientation to flexibly connect, it can make the rectangular frame of two symmetries firmly pack up or launch loading as required, in also driving simultaneously, the upper strata framework by after upwards dig about an angle of 90 degrees, form the firm effect that backrest cushion also can play the positioning supports backrest cushion.

Description of drawings is described further utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that forward and backward shelf of the present utility model launch scheme drawing.

Fig. 3 is a bidirectional spring supporting hinges structural representation of the present utility model.

The specific embodiment such as Fig. 1, shown in 2, the utility model comprises framework and frame strengthening beam, described framework is by bonding jumper or manages 1 and bend and combine, afterbody semicircular in shape or square, shelf 2 and back shelf 3 before dividing, be equipped with reinforcement 4 in the middle of each framework, back shelf 3 are three layers of identical with shape and overlapping frame structure that is installed together of size, it is upper strata framework 5, middle level framework 6 and lower floor's framework 7, before shelf 2 both sides frames by bidirectional spring supporting hinges 8 the upper-turn-type rectangular frame 9 of two symmetries is housed, two bonding jumpers extending in parallel forward of lower floor's framework 7 front ends or manage 1 tail end and bend to circular arc fixed connector 10 and captive joint in addition with rear shock absorber of motorcycle.The upper strata framework of being made up of framework 11 two and half fan-shaped symmetries and that can launch to the left and right 5 flexibly connects by hinge 12 and middle level framework 6, and framework 5 first halves in upper strata are equipped with backrest cushion 13, and lower part uses as back bar 14.Middle level framework 6 flexibly connects with the bidirectional spring supporting hinges 8 of energy self-orientation respectively with the frame of lower floor's framework 7 both sides.When utilizing the spring performance of bidirectional spring supporting hinges 5 that middle level framework 6 is kept flat in addition and lower floor's framework 7 tight joint, can drive upper strata framework 5 when starting and form backrest cushions 13, and can make the bracing frame of backrest cushion 13 and do not lose its steadiness.During lower floor's framework 7 of back shelf 3 can be done, upper strata framework 6 and 5 support.Between preceding shelf 2 and back shelf 3, establish a crossbeam 15 and reinforce, also establish a plate washer 16 in the middle part of crossbeam 15.As shown in Figure 3, bidirectional spring supporting hinges 8 that can self-orientation is to be combined by exert all one's strength positioning groove 18, bidirectional spring hinge adapter plate 19 and free bearing plate 20 of bilateral hinge spring 17, spring opening and closing.Bidirectional spring supporting hinges 8 has hinge and supports dual-use function, the stable support that is applicable to collapsible articles for use and can makes about an angle of 90 degrees be connected.
