Description

Technical Field

[0001] The utility model relates to the field of connection and installation of motorcycle covering parts, and particularly relates to an installation structure of a motorcycle front head covering part. Background Art

[0002] At present, the motorcycle front head covering part includes a headlight shield and an instrument shield. The headlight shield is a shell that is connected up, down, left and right, and is open at both the front and rear ends and penetrates through. The headlight shield is sleeved on the headlight, and the instrument shield is located behind the headlight shield. For the motorcycle front head covering part assembled with the above components, the mold opening cost of the headlight shield is high. To save costs, some motorcycle front head covering parts are assembled with an upper headlight shell, a headlight back plate and an instrument shield. Among them, the left and right sides of the upper headlight shell are bent downward in an arc shape, and the headlight back plate is placed under the upper headlight shell and is fixedly connected to the lower edges of the bending parts on both sides of the upper headlight shell through a plurality of clip nuts to form a headlight shield with openings at the front and rear. When installing the clip nuts, usually a lug with a through hole is arranged on one of the covering parts, the clip nut is stuck on the lug, and then the two covering parts are connected together by screwing a bolt with the clip nut. When assembling the bolt, the clip nut is often deformed due to excessive force. After the clip nut is deformed, it is very easy to deviate and fall off from the lug. At this time, it is necessary to disassemble and reinstall the covering parts to manually restore the clip nut to the undeformed state and reinstall the clip nut on the lug, which seriously affects the installation efficiency. Summary of the Invention

[0003] Aiming at the above-mentioned deficiencies existing in the prior art, the purpose of the utility model is to provide an installation structure of a motorcycle front head covering part, which solves the problem that the clip nut at the connection part of the existing motorcycle front head covering part is usually deformed due to improper operation during the assembly process, and the re-installation affects the assembly efficiency of the covering part.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An installation structure for a motorcycle front head covering, comprising an upper headlight housing, a headlight back plate, and an instrument shield; the front end and the left and right sides of the upper headlight housing are bent downward to form bent portions, the headlight back plate is placed below the bent portions, and the outer edge is clamped and fixed inside the bent portions; the instrument shield is placed at the rear end of the upper headlight housing, the upper end is clamped and fitted with the inner side of the upper headlight housing, the lower end is horizontally bent forward to the front end of the upper headlight housing, and is clamped and fixed with the headlight back plate; on the left and right sides of the side of the headlight back plate facing the upper headlight housing, two mounting lugs are respectively provided, and there is an assembly gap between each mounting lug and the bent portion, and on the left and right sides or one side of each mounting lug, a reinforcing side plate is provided, and on the inner side of one or both of the reinforcing side plates of each mounting lug, a limiting rib is provided; on each mounting lug, a clip nut A is provided, the clip nut A is U-shaped, one side is clamped at the assembly gap, and the other side abuts against the corresponding limiting rib; after the upper headlight housing passes through the corresponding mounting lug on its bent portion and the headlight back plate with bolts, it is threadedly engaged with the internal threaded hole of the clip nut A on the mounting lug. In this way, the upper headlight housing and the headlight back plate, and the front instrument shield and the upper headlight housing and the headlight back plate are initially positioned and fixed by clamping, and at the same time, the upper headlight housing and the headlight back plate are also fastened by four clip nuts A and bolts, and the connection structure is stable. The reinforcing side plates provided on both sides of each mounting lug can increase the strength of the mounting lug, and at the same time, it is also convenient for the setting of the limiting ribs. The assembly gap between the mounting lug and the upper headlight housing can limit and clamp one side plate of the clip nut A, and the limiting rib on the reinforcing side plate is located on one side of the other side plate of the clip nut A, so that the other side plate of the clip nut A can be limited, so that after the clip nut A is assembled, both side plates are limited and fixed. Therefore, when installing the bolt, even if the installer uses too much force, after the clip nut A is resisted, it is not easy to deform, thus avoiding the problems of clip nut offset and falling off and the need for re-assembly, and can effectively improve the installation efficiency of the front head covering. At the same time, the provided limiting ribs are integrally injection-molded with the headlight back plate, and the manufacturing cost is low.

[0006] Furthermore, a connecting lug is provided on the inner side of each of the two bent portions of the upper housing of the headlamp. The connecting lug is parallel to the instrument shield. A reinforcing plate is provided on each side of each connecting lug, and a nut limiting plate is provided on the inner side of one or both of the reinforcing plates of each connecting lug. A clip nut C with one side closely attached to the nut limiting plate is clamped on each connecting lug. After a connecting bolt passes through the instrument shield and the connecting lug, the instrument shield is in threaded cooperation with the clip nut C. In this way, in addition to the outer edge clamping fit between the upper housing of the headlamp and the instrument shield, the clip nut C and the connecting bolt are also used for locking and fixing, and the connecting structure is stable. Similarly, the clip nut C can be clamped between the connecting lug and the upper housing of the headlamp. The nut limiting plate on the reinforcing plate of the connecting lug can limit the side plate of the clip nut C to prevent the clip nut C from shifting or falling off, and improve the assembly efficiency between the upper housing of the headlamp and the instrument shield.

[0007] Furthermore, an assembly hole is provided in the middle of each of the clip nut A and the clip nut C, and two limiting grooves are provided at the upper ends of each mounting lug and each connecting lug. A limiting protrusion that cooperates with the assembly holes on the clip nut A and the clip nut C is formed between the two limiting grooves. In this way, when the clip nut is assembled, in addition to being limited by the nut limiting plate and the limiting rib, it can also be positioned by being tightly clamped with the limiting protrusion to prevent the clip nut from shifting after installation.

[0008] Furthermore, a plurality of limiting blocks and positioning blocks are provided at intervals on the inner side of the rear end of the upper housing of the headlamp. The upper end of the instrument shield is provided with a flanging that cooperates with the limiting blocks, and a plurality of positioning holes that cooperate with the positioning blocks are provided on the flanging. In this way, the provided limiting blocks can limit the installation position of the instrument shield, and the cooperation between the positioning blocks and the positioning holes can tightly clamp and fit the upper housing of the headlamp and the instrument shield together.

[0009] Furthermore, two upwardly protruding fixing portions are provided in the middle of the rear end of the headlamp back plate. A clip nut B is clamped and fitted on the fixing portion. After a fastening bolt passes through the instrument shield and the fixing portion, the lower end of the instrument shield is in threaded cooperation with the clip nut B. In this way, in addition to the outer edge clamping fit between the headlamp back plate and the instrument shield, they are also fixedly connected by fasteners, and the installation structure is stable.

[0010] Furthermore, a perforation is provided on the fixing portion of the headlamp back plate, and a mounting hole corresponding to the perforation is provided on the instrument shield. In this way, after the perforation and the mounting hole are provided, it is convenient for the installation of the fastening bolt. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Such as Figures 1-5As shown in the figure, the installation structure of the motorcycle front head covering provided in this embodiment includes an upper headlight housing 1, a headlight back plate 2, and an instrument shield 3. The front end and the left and right sides of the upper headlight housing 1 are bent downward to form bent portions. The headlight back plate 2 is placed under the bent portions, and its outer edge is clamped and fixed inside the bent portions. The instrument shield 3 is vertically arranged and is placed at the rear end of the upper headlight housing 1. The upper end is clamped and fitted with the inner side of the upper headlight housing 1. The lower end is bent horizontally forward to the front end of the upper headlight housing 1 and is closely attached to and clamped and fixed to the outer side of the rear end of the headlight back plate 2. On the left and right sides of the surface of the headlight back plate 2 facing the upper headlight housing 1, two mounting lugs 21 are respectively provided. There is an assembly gap between each mounting lug 21 and the bent portion. And on the left and right sides of each mounting lug 21, a reinforcing side plate 24 is provided (in actual implementation, the reinforcing side plate 24 can be provided only on one side). On the inner side of one of the reinforcing side plates 24 or both of the reinforcing side plates 24 of each mounting lug 21, a limiting rib 25 is provided (the limiting rib 25 is arranged parallel to the mounting lug 21. When specifically setting, the limiting rib 25 can be set as a flat plate with a bolt through hole in the middle). On each mounting lug 21, a clip nut A4 is provided. The clip nut A4 is U-shaped. One side is clamped at the assembly gap, and the other side abuts against the corresponding limiting rib 25. After the upper headlight housing 1 passes through the bent portion thereof and the corresponding mounting lug 21 on the headlight back plate 2 with bolts 5, it is threadedly engaged with the internal thread hole of the clip nut A4 on this mounting lug 21. On the inner sides of the two bent portions of the upper headlight housing 1, a connecting lug 11 is provided. The connecting lug 11 is parallel to the instrument shield 3. On both sides of each connecting lug 11, a reinforcing plate 12 is provided. On the inner side of one of the reinforcing plates 12 or both of the reinforcing plates 12 of each connecting lug 11, a nut limiting plate 13 is provided. On each connecting lug 11, a clip nut C6 with one side closely attached to the nut limiting plate 13 is clamped (the clip nut C6 has the same structure as the clip nut A4). The instrument shield 3 passes through the instrument shield 3 and the connecting lug 11 with a connecting bolt 7 and is threadedly engaged with the clip nut C6. In the middle of the rear end of the headlight back plate 2, there are two upwardly protruding fixing portions 26. A clip nut B (not shown in the figure) is clamped and fitted on the fixing portions 26. The lower end of the instrument shield 3 passes through the instrument shield 3 and the fixing portions 26 with fastening bolts and is threadedly engaged with the clip nut B. In this way, between the upper headlight housing 1 and the headlight back plate 2, and between the front instrument shield 3 and the upper headlight housing 1 and the headlight back plate 2, they are all initially positioned and fixed by means of clamping and fitting. At the same time, between the upper headlight housing 1 and the headlight back plate 2, they are also fastened by four clip nuts A4 and bolts, and the connection structure is stable. And the reinforcing side plates 24 provided on both sides of each mounting lug 21 can increase the strength of the mounting lug 21. At the same time, it is also convenient for the setting of the limiting rib 25.The assembly gap between the mounting lug 21 and the front headlight upper housing 1 can limit and clamp one side plate of the clip nut A4. The limiting rib 25 on the reinforcing side plate 24 is located on one side of the other side plate of the clip nut A4, so as to be able to limit the other side plate of the clip nut A4. After the clip nut A4 is assembled, both side plates are limited and fixed. Therefore, when installing the bolt, even if the installer applies excessive force, the clip nut A4 is not easily deformed after being resisted, thus avoiding the problems of the clip nut offsetting and falling off and the need for re-assembly, and effectively improving the installation efficiency of the front-end covering parts. At the same time, the provided limiting rib 25 is integrally injection-molded with the front headlight back plate 2, and the manufacturing cost is low. In addition to the outer edge clamping fit between the front headlight upper housing 1 and the instrument shield 3, the clip nut C6 and the connecting bolt 7 are also used for locking and fixing, and the connection structure is stable. Similarly, the clip nut C6 can be clamped between the connecting lug 11 and the front headlight upper housing 1, and the nut limiting plate 13 on the reinforcing plate 12 of the connecting lug 11 can limit the side plate of the clip nut C6 to avoid the clip nut C6 from offsetting and falling off, and improving the assembly efficiency between the front headlight upper housing 1 and the instrument shield 3. In addition to the outer edge clamping fit between the front headlight back plate 2 and the instrument shield 3, they are also connected and fixed by fasteners, and the installation structure is stable.

[0019] Further, an assembly hole is provided in the middle of each of the clip nut A4 and the clip nut C6, and two limiting grooves 22 are provided at the upper ends of each of the mounting lugs 21 and the connecting lugs 11. A limiting protrusion 24 that cooperates with the assembly holes on the clip nut A4 and the clip nut C6 is formed between the two limiting grooves 22. In this way, when the clip nut is assembled, in addition to being limited by the nut limiting plate 13 and the limiting rib 25, it can also be positioned by being tightly fitted with the limiting protrusion 24 to avoid the clip nut from offsetting after installation.

[0020] Further, a plurality of limiting blocks 14 and positioning blocks 15 are provided at intervals on the inner side of the rear end of the front headlight upper housing 1. The upper end of the instrument shield 3 is provided with a flanging 31 that cooperates with the limiting blocks 14, and a plurality of positioning holes 32 that cooperate with the positioning blocks 15 are provided on the flanging 31. In this way, the provided limiting blocks 14 can limit the installation position of the instrument shield 3, and the cooperation between the positioning blocks 15 and the positioning holes 32 can tightly fit the front headlight upper housing 1 and the instrument shield 3 together.

[0021] Further, a through hole is provided on the fixing portion 26 of the front headlight back plate 2, and a mounting hole corresponding to the through hole is provided on the instrument shield 3. In this way, after the through hole and the mounting hole are provided, it is convenient to install the fastening bolt.

[0022] For the convenience of installation, holes for the bolt to pass through are provided on the front headlight upper housing 1, the mounting lugs 21, and the instrument shield 3.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. Those of ordinary skill in the art should understand that any modifications or equivalent replacements made to the technical solutions of the present utility model without departing from the spirit and scope of the technical solutions shall be covered by the scope of the claims of the present utility model.
