DETAILED DESCRIPTION OF THE EMBODIMENTS

Best Implementations of the Present Disclosure

[0032] The present disclosure will be further described below with reference to specific embodiments.

[0033] FIG. 1 is a front view of a horizontally provided flow guide wing according to the present disclosure. FIG. 2 is a side view of a horizontally provided flow guide wing according to the present disclosure. In the figures, 1 represents helmet body, and 2 represents flow guide wing. The flow guide wing 2 is horizontally fixed at each of two sides of the helmet body 1.

[0034] FIG. 3 is a schematic view illustrating that a flow guide wing is horizontally provided on a guiding cover according to the present disclosure. Guiding cover 3 is provided at a back of the helmet. This can reduce a wind resistance of the helmet. As an embodiment, the flow guide wing 2 is horizontally provided on the guiding cover 3.

[0035] FIG. 4 is a front view of a vertically provided flow guide wing according to the present disclosure. FIG. 5 is a side view of a vertically provided flow guide wing according to the present disclosure. In the figures, 1 represents helmet body, and 2 represents flow guide wing. The flow guide wing 2 is vertically fixed at each of two sides of the helmet body 1.

[0036] FIG. 6 is a schematic view illustrating that a flow guide wing is vertically provided on a guiding cover according to the present disclosure. Guiding cover 3 is provided at a back of the helmet. This can reduce a wind resistance of the helmet. As an embodiment, the flow guide wing 2 is vertically provided on the guiding cover 3.

[0037] In Embodiments 1-6, it is to be understood that there may be at least one flow guide wing 2 on a left and a right of the helmet body 1, and may also be a plurality of flow guide wings 2. For example, there are two layers of flow guide wings that are parallel to each other. In case of a fluid in forward movement of the helmet body 1, the flow guide wing 2 generates a lift, and transmits the lift to the helmet body 1.

[0038] FIG. 7 is a schematic view illustrating connection between a flow guide wing and a helmet according to the present disclosure. Fixed tray 10 is provided. The fixed tray 10 is fixed on the helmet. At least one clamping groove 11 is formed in the fixed tray 10. In the figure, there are horizontal and vertical clamping grooves 11. A plurality of clamping grooves 11 have an open end and are circumferentially distributed along an axis of the fixed tray 10. An opening direction of the clamping groove 11 is toward an advancing direction of the helmet in use. A left end of the flow guide wing 2 can be embedded into the clamping groove 11. A portion of the flow guide wing 2 embedded into the clamping groove 11 and the clamping groove 11 are in interference fit and are fixed to each other through at least one of a mortise-and-tenon structure and a buckle structure. It is to be understood that a same clamping groove may also be formed in the flow guide wing 2. The clamping groove and a portion of the fixed tray 10 cooperating with the clamping groove are embedded into each other for fixation.

[0039] It is to be understood that an open position of the clamping groove 11 may be inclined upward with a certain angle. After the flow guide wing 2 is fixed in the clamping groove 11, the flow guide wing 2 can form an angle of attack with a horizontal plane. Particularly, in response to a symmetrical shape of the flow guide wing, through the angle of attack with the horizontal plane, the flow guide wing 2 also has an angle of attack relative to an oncoming fluid through movement of the head in use. This can improve the lift of the flow guide wing 2. In the figure, the flow guide wing 2 not used can be detached for storage.
