Abstract

The invention provides a rear rack device which comprises a rear rack made of metal. A groove is formed in the middle of the front edge of the rear rack. Circular holes for screws are formed on the periphery of the groove. The rear rack can be fixed at the tail of a vehicle through the circular holes and the screws. A plurality of threaded holes are formed in the lower surface of the rear rack. The rear rack device is capable of bearing more and heavier goods, cost-saving and easy to expand, goods delivering requirements are satisfied, and other structures can be cooperated with the rear rack device to increase application diversity and attractiveness.

Description

Rear rack device

Technical field

The present invention relates to a kind of accessory for cart, relate in particular to a kind of rear rack device that is applied to the cart afterbody.

Background technology

Cart, such as bicycle, Electrical Bicycle, motor bike etc. has been widely used, and along with market and technical development, its applicable crowd is also in differentiation.The user has proposed different requirements to vehicle, and the customer requirements that for example has is attractive in appearance, and some requirements can load-carrying, and requiring of having is small and exquisite.For the rear shelf of vehicle, present rear shelf or be integral structure can't be adjusted; Perhaps be the same material, can't when reducing cost, have both satisfied requirement of strength, can satisfy requirement attractive in appearance again.

Summary of the invention

The object of the present invention is to provide a kind of rear rack device, with solve existing after shelf can't adjust structure and cost and alerting ability and the problem such as can't take into account.

In order to address the above problem, the invention provides a kind of rear rack device, it comprises rear shelf, the material of described rear shelf is metal material, the front edge of described rear shelf middle part is provided with groove, thus described groove around be provided be used to the circular hole that passes screw described rear shelf are fixed in vehicle tail; The lower surface of described rear shelf is provided with a plurality of tapped bore.

A kind of preferred implementation according to above-mentioned rear rack device, wherein, also comprise: extend shelf, be framed structure, the front end of described extension shelf is provided with the first through hole, described the first through hole is corresponding with described tapped bore, the front end of described extension shelf is fixed in the lower surface of described rear shelf by screw.

A kind of preferred implementation according to above-mentioned rear rack device, wherein, also comprise: cover panel, be plastic cement material, be tabular, and described cover panel is provided with a plurality of the second through holes, described cover panel is covered in the lower surface of described rear shelf, and described the second through hole is corresponding with described tapped bore, described cover panel is fixed in the lower surface of described rear shelf by screw.

According to a kind of preferred implementation of above-mentioned rear rack device, wherein, described rear shelf are the cast aluminium material.

According to a kind of preferred implementation of above-mentioned rear rack device, wherein, described extension shelf are irony.

A kind of preferred implementation according to above-mentioned rear rack device, wherein, described extension shelf comprise the first strut bar, the second strut bar and the pipe link linearly that all is U-shaped, it is inner that described the first strut bar is positioned at described the second strut bar, described pipe link is connected in described the first strut bar, the second strut bar simultaneously, and the front end of described the first strut bar and the second strut bar is provided with described the first through hole.

By changing the structure of rear shelf, the present invention can be carried more, heavier goods, satisfies the transporting cargo requirement, saves simultaneously cost, is easy to expansion, can configure other structures, to increase variety and the aesthetic feeling of using.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further details.

Fig. 1 shows the spatial structure of the embodiment of the invention one, and it mainly comprises rear shelf 1, and it is the disk-shaped structure of back-off, and part edge is to downward-extension.The material of rear shelf 1 is metal material, is preferably the cast aluminium material.And existing rear shelf with similar structures are plastic material at present, only have decorative effect, are difficult to carry weight, more can't expand, fix, connect other structures.Such as Fig. 1, the front edge middle part of rear shelf 1 is provided with groove 10, thereby be provided be used to the circular hole 11 that passes screw rear shelf 1 are fixed in vehicle tail around the groove 10, the both wings that extend forward groove 10 both sides can increase overlapping area with vehicle tail, in order to more circular hole 11 is set.In order to have expanded succinct other structures, the lower surface of rear shelf 1 is provided with a plurality of tapped bore 12(as shown in Figure 2, because the structure of the rear shelf 1 of Fig. 1 and Fig. 2 is identical).

Such as Fig. 2 and Fig. 2, in order to increase the length of rear shelf 1, embodiments of the invention two also comprise extension shelf 3, it is framed structure, the front end that extends shelf 3 is provided with the first through hole 34, the first through hole 34 is corresponding with tapped bore 12, is fixed in the lower surface of rear shelf 1 with the front end that will extend shelf 3 by screw.

More preferably, extending shelf 3 is irony, and comprise the first strut bar 31, the second strut bar 32 and the pipe link linearly 33 that all are U-shaped, the first strut bar 31 is positioned at the second strut bar 32 inside, the front end that pipe link 33 is connected in the first strut bar 31, the second strut bar 32, the first strut bars 31 and the second strut bar 32 simultaneously is provided with the first through hole 34.

Boot and other goods of binding can be set on the extension shelf 3 of framed structure.

Such as Fig. 4-shown in Figure 7, except rear shelf 1, the embodiment of the invention three also comprises cover panel 2, it is plastic cement material, be tabular, and cover panel 2 is provided with a plurality of the second through holes 21, cover panel 2 is covered in the lower surface of rear shelf 1, and the second through hole 21 is corresponding with tapped bore 12, cover panel 2 is fixed in the lower surface of rear shelf 1 by screw.

The lower surface of the embodiment of the invention three is closed with cover panel 2, and is not only specious, and saved metallic material, because the plastic material price is relatively cheap, so this embodiment three can reduce cost, and can select more multi-configuration item, style.

To sum up, the present invention can be carried more goods so that the rear shelf of cart have larger structural strength by material and the structure of shelf after changing, and carries out as required different expansions, satisfies more diversified demand.

As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all is casehistory, is not only.All within the scope of the present invention or the change within being equal to scope of the present invention all be included in the invention.
