Specific implementation method:

[0030] The present invention is further described below with specific embodiments:

[0031] like Figure 1-Figure 10 As shown, the utility model provides a motorcycle helmet with a retractable tail wing, the motorcycle helmet comprises a helmet body 1, a tail wing 2, a tail wing seat 3 is arranged at the rear end of the helmet body 1, a tail wing cover 4 is arranged above the tail wing seat 3, the tail wing cover 4 and the tail wing seat 3 are fixedly connected to the helmet body 1, and the tail wing 2 is retractably arranged between the tail wing cover 4 and the tail wing seat 3. The tail wing 2 of the utility model is retractable by sliding, and is a pull-out structure. When the tail wing 2 is extended outward, it is a large tail wing, which can reduce air resistance and is suitable for occasions such as racing. When the tail wing 2 is pushed inward and retracted, it is a small tail wing, which is suitable for daily riding occasions. Consumers can choose and switch between the large tail wing and the small tail wing.

[0032] Further, if Figure 2 and Figure 4 As shown, the tail seat 3 is provided with two or more first mounting holes 5 at intervals. In this embodiment, two first mounting holes 5 are provided, which are strip holes whose long axes are consistent with the telescopic direction of the tail 2 and are symmetrically arranged. The first mounting holes 5 are provided as strip holes, which can reduce the processing requirements. The helmet body 1 is provided with second mounting holes 6 corresponding to the positions and numbers of the first mounting holes 5. The bottom surface of the tail cover 4 is provided with first connecting columns 7 corresponding to the positions and numbers of the second mounting holes 6. The first connecting columns 7 pass through the first mounting holes 6 and are connected to the second mounting holes 6.

[0033] Specifically, the first connecting column 7 includes a first column body 8, a first strip opening 9 is axially arranged at one end of the first column body 8, and a first limiting protrusion 10 is arranged outward at one end of the first column body 8. The first connecting column 7 is deformed through the first strip opening 9 to pass through the first mounting hole 5, and the first limiting protrusion 10 is limited to the bottom surface of the second mounting hole 6, thereby playing an axial limiting role.

[0034] like Figure 3 , Figure 4 , Figure 8 and Fig.10 As shown, the bottom surfaces of both ends of the tail wing cover 4 are provided with second connecting columns 11 , and the corresponding positions of the helmet body 1 are provided with third mounting holes 12 , and the second connecting columns 11 are connected to the third mounting holes 12 .

[0035] In addition, if Figure 3 and Figure 7As shown, the two ends of the tail wing 2 of the utility model are provided with first strip holes 13, and the second connecting column 11 passes through the first strip holes 13 and is connected to the third mounting hole 12. In this way, the connection between the tail wing cover 4, the tail wing 2 and the helmet body 1 is realized at the same time, and the structure is simple and compact. The provision of the first strip hole 13 also facilitates the tail wing 2 to rotate around the connecting column 11 without getting stuck.

[0036] Likewise, if Fig.10 As shown, the second connecting column 11 includes a second column 14, a second strip opening 15 is axially arranged at one end of the second column 14, and a second limiting protrusion 16 is arranged outward at one end of the second column 14. The second connecting column 11 is deformed through the second strip opening 15 to pass through the third mounting hole 12, and the limiting protrusion 16 is limited to the bottom surface of the third mounting hole 12 to achieve axial limitation.

[0037] like Figure 2 and Figure 6 As shown, the utility model further provides a fourth mounting hole 17 on the tail wing seat 3, and a third connecting column 18 is provided on the bottom surface of the tail wing cover 4, and the position and number of the third connecting column 18 correspond one to one with the fourth mounting hole 17, and the fastener passes through the fourth mounting hole 17 and is connected to the end surface of the third connecting column 18, so as to realize the fixed connection between the tail wing cover 4 and the tail wing seat 3.

[0038] In addition, if Figure 7 As shown, the tail wing 2 of the utility model is provided with a second strip hole 19, and the third connecting column 18 passes through the second strip hole 19 and is connected to the fourth mounting hole 17. When the tail wing 2 is extended or retracted, the second strip hole 19 has a certain guiding effect, and the structure is compact. The length of the second strip hole 19 is the travel of the tail wing 2 to be extended or retracted.

[0039] In order to prevent the tail wing 2 from being displaced after being extended or retracted into position, Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the utility model provides a limiting guide hole 20 on the tail wing 2, and a extending-in-place limiting groove 21 and a retracting-in-place limiting groove 22 are provided on the limiting guide hole 20. A limiting protrusion 23 is provided on the tail wing cover 4, and the limiting protrusion 23 realizes the positioning of the tail wing 2 when being matched and connected with the extending-in-place limiting groove 21 or the retracting-in-place limiting groove 22.

[0040] In order to make the expansion and contraction more stable, Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a plurality of guide ridges 24 are arranged at intervals on the tail wing seat 3 , and a guide groove 25 is arranged at a corresponding position on the tail wing 2 , and the guide ridges 24 are arranged in the guide groove 25 .

[0041] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
