The bracket is formed by punching a plate, the middle part of the bracket is provided with a pi-shaped arch bar, and the top part of the arch bar is provided with a backpanel mounting hole; the rear side of the arch bar is provided with an L-shaped support plate, the riser of the support plate is connected with the top part of the arch bar, and the cross slab of the support plate is provided with a rear fender back mounting hole; wing plates are arranged at the two sides of the arch bar, the inner end of each wing plate is connected with the bottom end of the arch bar, and the outer end of each wing plate bends downwards to form a bevel board which is provided with a rear fender front mounting hole; and all the wing plates at the two sides of the arch bar are connected with vertical boards, and the bottom end of each vertical board is welded on the tail pipe of the bracket. By integrating the backpanel mounting hole, the rear fender front mounting hole and the rear fender mounting hole into the same bracket, the assembly of the backpanel and rear fenders has small error, the product assembly consistence is good, the production efficiency is high, and the jointclose effect between the backpanel and each rear fender tail lamp can be ensured.

Description

The bracket at tail part of motorbike combination

Technical field

The present invention relates to a kind of motor bike member, the particularly mounting bracket of motor bike afterbody cover panel combination.

Background technology

Rear end panel and rear mudguard are installed on the afterbody of frame of motorcycle, play a part to cover the motor bike rear part, beautify motor bike rear portion appearance.Like Fig. 5, Fig. 6, shown in Figure 7, the welding bearing 4 in the rear end of vehicle frame tail pipe 1, the welded top of this bearing 4 " Z " shape journal stirrup 5, " Z " shape journal stirrup 5 last slice offer the rear end panel mounting hole so that through bolted connection rear end panel 7; Z " following of shape journal stirrup offer mounting hole behind the rear mudguard.At said Z " left and right sides in shape journal stirrup 5 the place aheads symmetry welding " 7 " font journal stirrup 6; offer mounting hole before the rear mudguard on each " 7 " font journal stirrup 6; mounting hole and Z before the rear mudguard on both sides " mounting hole matches behind the rear mudguard on the shape journal stirrup, be connected with rear mudguard 8 through bolt separately.Because " 7 " font journal stirrup 6, Z " shape journal stirrup 5 and bearing 4 moulding respectively; be welded on successively on the vehicle frame tail pipe, and rely on workman's experience to confirm rigging position fully welding the time, not only production efficiency is low; the conformability of product assembling is poor; and error is bigger, because of the welding error causes between the taillight on rear end panel and the rear mudguard joint close relatively poor easily, thereby influences the appearance at motor bike rear portion.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of accurate positioning failure-free bracket at tail part of motorbike combination.

Technical scheme of the present invention is following: a kind of bracket at tail part of motorbike combination, comprise vehicle frame tail pipe and support,

Its key is:

A, in the rear end of said vehicle frame tail pipe support is set, this support is by the plate punch forming, and the middle part of said support forms " ∏ " shape arch bar to arch, and the top of this arch bar has the rear end panel mounting hole;

B, be provided with " L " shape support plate at the rear side of said arch bar, the riser of this support plate links to each other with the top of arch bar, mounting hole after having rear mudguard on the transverse slat of support plate;

C, be provided with wing plate in the both sides of said arch bar, the inner of this wing plate links to each other with the bottom of arch bar, and the outer end of wing plate bends downwards, forms swash plate, and has mounting hole before the rear mudguard on the swash plate;

All be connected with riser on the wing plate of D, said arch bar both sides, the bottom of each riser is welded on the vehicle frame tail pipe.

Support among the present invention is welded on the vehicle frame tail pipe through the riser on both sides, and it is firm that the one side support is connected with the vehicle frame tail pipe, can not take place to become flexible and come off; On the other hand, support is fixed with the vehicle frame tail pipe through 2, support accurate positioning on the vehicle frame tail pipe, reliable.Mounting hole all is integrated on the same support behind rear end panel mounting hole, the preceding mounting hole of rear mudguard and the rear mudguard; The position of each mounting hole on support is to confirm unmodified; The error of assembling rear end panel and rear mudguard is little like this; The high conformity of product assembling, production efficiency is high, and can guarantee the joint close effect between the taillight on rear end panel and the rear mudguard.Support is through the plate punch forming, and not only processing and fabricating is convenient, fast, and the structural strength of self is good, and damage can not deform.Have circular knock hole at said wing plate near the position of bending place, outer end; Like this in welding support; Can be by frock clamp, cooperate with knock hole on the wing plate through the registration mast on the frock clamp, can guarantee support accurate positioning on the vehicle frame tail pipe, reliable; Improved welding efficiency greatly, helped conveyor line and assemble in batches.

The bottom of each mounting hole all is welded with nut on the said support.Nut is arranged on the support in advance, in the time of assembling rear end panel or rear mudguard, only need turns bolt and get final product, not only convenient but also quick.

Said riser is " eight " font and is symmetrically distributed in the both sides of arch bar.Above structure can be guaranteed the steadiness of support assembling, and simultaneously, the bending place of the position of riser and vehicle frame tail pipe adapts, and the zone of both contacts is big, has further improved the bonded assembly fixing.

Beneficial effect: the present invention is through all being integrated in mounting hole behind mounting hole and the rear mudguard before rear end panel mounting hole, the rear mudguard on the same support; Make that the error of assembling rear end panel and rear mudguard is little; The high conformity of product assembling; Production efficiency is high, and can guarantee the joint close effect between the taillight on rear end panel and the rear mudguard.
