Abstract

The utility model discloses a motorcycle tail box whose structure comprises a case body and a case cover, wherein the case cover is divided into a chassis and an upper surroundings around the upper part of the chassis. The improved utility model is characterized in that the chassis is fixedly connected with the upper surroundings via turning over the crimping of the upper surroundings. The utility model can realize the quick assembling of the products via the crimping device and is also simple and convenient to get processing with high efficiency and will not cause the pollution problem due to the welding joint and at the same time guarantee the whole appearance to be more beautiful. The utility model is also fit for manufacturing the trail box of the stainless steel motorcycle.

Description

A kind of motor bike boot

Technical field

The utility model relates to a kind of motor bike boot, the metal boot that particularly a kind of motor bike is used.

Background technology

The motor bike boot is divided into casing and case lid two parts, existing its casing of metal boot has plenty of all-in-one-piece, promptly forms by whole punching stretch, and such casing is owing to occur wrinkling easily in the punching stretch process, particularly circular arc is excessively located, and causes influencing the aesthetic measure of product; A kind of split type boot casing has appearred subsequently, be divided into the chassis and enclose to put on top, chassis and enclose two parts, two parts are fixedly connected by welding up and down, but because welding needs manual operation to carry out, and postwelding polished smooth solder joint for attractive in appearance also the needs, so just cause man-hour long-acting rate low, welding simultaneously exists pollutes, and solder joint expose that also still can to influence the casing single-piece attractive in appearance.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of easy to make, motor bike boot that production efficiency is high, and outward appearance do not have weld seam, and is attractive in appearance pollution-free.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of motor bike boot, comprise casing and case lid, wherein casing is divided into the chassis again and encloses to put on top, chassis and enclose, the crimping that dig by peripheral edge upwards on described chassis with on enclose and captive joint.

The beneficial effects of the utility model are: by the chassis make progress crimping that peripheral edge digs with the chassis with on enclose and captive joint, can realize quick assembling by crimping equipment, process simple and convenient, the efficient height, and there is not the pollution problem that was welded to connect originally, because the existence of crimping also makes the rigidity of casing itself obtain reinforcement, help the raising of product design and the reduction of cost simultaneously.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an integral structure scheme drawing of the present utility model;

Fig. 2 be the utility model chassis and on enclose the part sectional view of junction.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of motor bike boot comprises casing 1 and case lid 2, and wherein casing 1 is divided into chassis 3 again and encloses to put on top, chassis and encloses 4, described chassis 3 by the crimping 5 that upwards encloses 4 edges and dig with on enclose 4 and captive joint.

Casing 1 is earlier with chassis 3 punch formings when making, the pre-flange in edge, then will on enclose 4 and be enclosed within on the flange on chassis 3, utilize crimping equipment that the flange on chassis 3 is curled at last and superscribe the crimping 5 that encloses 4 lower edges.Need not artificial welding operation owing to adopting mechanical equipment to carry out crimping, therefore process simple and convenient, the efficient height; Simultaneously, because the existence of crimping also makes casing under the situation that does not increase the thickness of material own, rigidity still can be improved and strengthen, promoted product design greatly, or as reaching same rigidity, adopt crimping bonded assembly structure can use thin material, also help reducing the manufacturing cost of product.

The motor bike boot in use needs frequent opening and closing, for the edge that prevents casing 1 and case lid 2 scratch human body in use, its peripheral bead promptly can be provided with the case lid crimping 6 of outside turnover at the case lid edge, enclose on the casing 4 end edge be provided with inside turnover on enclose crimping 7.

Claims

1. motor bike boot, comprise casing (1) and case lid (2), wherein casing (1) is divided into chassis (3) again and encloses to put and enclose (4) on top, chassis, it is characterized in that: described chassis (3) by the crimping (5) that upwards encloses (4) edge and dig with on enclose (4) and captive joint.

2. a kind of motor bike boot according to claim 1 is characterized in that: there is the case lid crimping (6) of outside turnover at described case lid (2) edge.

3. a kind of motor bike boot according to claim 1 is characterized in that: enclose on the described casing (4) end edge have inside turnover on enclose crimping (7).
