2019 AUG 14 (NewsRx) -- By a News Reporter-Staff News Editor at Daily Asia Business -- A patent by the inventors Matsuo, Tomoya (Wako, Japan); Noguchi, Yuji (Wako, Japan); Nagasaki, Masanobu (Maibara, Japan), filed on September 7, 2017, was published online on August 12, 2019, according to news reporting originating from Alexandria, Virginia, by NewsRx correspondents.

Patent number 10,363,984 is assigned to Honda Motor Co. Ltd. (Minato-ku, Tokyo, Japan).

The following quote was obtained by the news editors from the background information supplied by the inventors: “Conventionally, a body cover structure in which a rib abutting on a radiator is formed on an inner surface of a shroud for covering the radiator laterally is known (for example, see Patent Literature 1).”

In addition to the background information obtained for this patent, NewsRx journalists also obtained the inventors’ summary information for this patent: “Technical Problem

“In the structure described in Patent Literature 1, a pair of ribs abutting on the radiator protrude from the inner surface of the shroud, and when the ribs contact the radiator supposed to get hot, there is a concern about thermal influence on the ribs. Furthermore, since the distal end of each rib is pointed, the surface pressure generated at the distal end of each rib increases, making it more likely to cause deformation or abrasion of the rib.

“The present invention has been achieved in view of the above-mentioned circumstances, and it is an object thereof to provide a body cover structure for a saddle riding vehicle which can suppress thermal influence on a component abutting on an engine or a component supposed to get hot relating to the engine and deformation or abrasion of the component, in a body cover.

“Solution to Problem

“In order to achieve the object, according to a first feature of an aspect of the present invention, there is provided a body cover structure for a saddle riding vehicle which includes a body cover (50, 51, 201) made of fiber-reinforced resin for covering an outside of a vehicle body. A protruding portion (66, 67, 89, 202) is provided inside the body cover (50, 51, 201) covering an outside of an engine (10) or a component (38, 39, 41) supposed to get hot, the component (38, 39, 41) relating to the engine (10). An abutting surface (66e, 89e, 202g) to abut on the engine (10) or the component (38, 39, 41) is provided at a distal end of the protruding portion (66, 67, 89, 202). The protruding portion (66, 67, 89, 202) is made of resin material with higher heat resistance than a cover body (56, 81) constituting the body cover (50, 51, 201).

“According to a second feature of the present invention, in addition to the first feature, the protruding portion (66, 67, 89) may have a hollow structure formed by an outer peripheral wall (66a, 89a) erected from the cover body (56, 81) of the body cover (50, 51) and an inner wall (66c, 89c) provided at a top of the outer peripheral wall (66a, 89a), and the abutting surface (66e, 89e) may be formed on the inner wall (66c, 89c).

“According to a third feature of the present invention, in addition to the first or second feature, the body cover may be a radiator shroud (50) for covering an outside of a radiator (41) and the protruding portion (66, 67) may abut on an outside surface of the radiator (41).

“According to a fourth feature of the present invention, in addition to the first or second feature, the body cover may be a side cover (51) located under a lateral portion of a seat (13), covering an outside of a muffler (38, 39), and the protruding portion (89) may abut on an outside surface of the muffler (38, 39).

“According to a fifth feature of the present invention, in addition to any one of the first to fourth features, the protruding portion (66, 67) may be made of fiber-reinforced resin and fiber of the protruding portion (66, 67) may have higher strength and higher heat resistance than fiber of a resin member (56) of the body cover (50).

“According to a sixth feature of the present invention, in addition to the fifth feature, the fiber of the resin member (56) of the body cover (50) may be carbon fiber and the fiber of the protruding portion (66, 67) may be Kevlar fiber.

“According to a seventh feature of the present invention, there is provided a body cover structure for a saddle riding vehicle which includes a body cover (50, 51, 201) made of fiber-reinforced resin for covering an outside of a vehicle body. A protruding portion (66, 67, 89, 202) is provided inside the body cover (50, 51, 201) covering an outside of an engine (10) or a component (38, 39, 41) supposed to get hot, the component (38, 39, 41) relating to the engine (10). The protruding portion (66, 67, 89, 202) is configured as a separate component from a cover body (56, 81) constituting the body cover (50, 51, 201) and the protruding portion (66, 67, 89, 202) is made of resin material with high heat resistance. An abutting portion (66e, 89e, 202g) to directly abut on the engine (10) or the component (38, 39, 41) is provided at a distal end of the protruding portion (66, 67, 89, 202).

“Advantageous Effects of Invention

“With the first feature of an aspect of the present invention, the protruding portion can have high heat resistance and due to the presence of the abutting surface on the protruding portion, the surface pressure generated on the abutting surface can be decreased. Consequently, thermal influence on the protruding portion or deformation or abrasion of the protruding portion can be suppressed.

“With the second feature, the protruding portion can be light and highly rigid and highly heat-resistant. Consequently, the body cover can be light and if an external force is applied to the body cover, deformation of the protruding portion can be suppressed and further the protruding portion is less susceptible to thermal influence.

“With the third feature, even if the protruding portion of the radiator shroud contacts the outside surface of the hot radiator, it can resist the high temperature of the radiator.

“With the fourth feature, even if the protruding portion of the side cover contacts the outside surface of the hot muffler, it can resist the high temperature of the muffler.

“With the fifth and sixth features, the protruding portion can have higher strength and thermal influence on it can be further suppressed.

“With the seventh feature, the protruding portion can be highly heat-resistant and due to the presence of the abutting portion to abut on the protruding portion directly, it is only necessary to increase the heat resistance of the protruding portion and thus the structure can be simple and compact.”
