Description

[Detailed explanation of the invention] (Field of industrial application) This invention is based on the hood structure of an automobile, specifically, an upwardly bulging portion with an opening in the front is provided to introduce wind from the vehicle into the engine compartment. This relates to the hood structure of automobiles.

(Prior Art) In general, a hood panel that covers the upper part of an engine room in an openable and closable manner is composed of an outer panel and an inner panel, and both panels are joined to each other by hemming at their peripheral edges, and
Other than the periphery, the edges of the reinforcements formed at important points on the inner panel, the areas around the weight reduction holes, etc. are bonded to the outer panel by bonding them to the lower surface of the outer panel via an adhesive. The outer panel and the inner panel face each other with a predetermined distance (space) apart from each other except for the joint portion.

On the other hand, the hood structure of a car equipped with a turbocharger has an upward bulge with an opening in the front in order to introduce running air into cooling equipment such as an intercooler installed in the engine room. Something is known (for example, Utility Model 58-43556)
Publication No.).

The upper bulge is formed by partially pushing up the outer panel, thereby forming an opening for air intake in the front surface of the upper bulge, through which the running wind is introduced, It is sent to cooling equipment such as an intercooler through the inside of the upper bulge. That is, the running wind passes from the air intake opening formed in the outer panel through the space formed by the inner surface of the upward bulge and the upper surface of the inner panel located below this upward bulge. It passes through an opening provided in the inner panel at a lower position corresponding to the upper bulge and is sent to a cooler such as an intercooler provided in the engine room.

However, the space formed by the inner surface of the upper bulge and the upper surface of the inner panel located below the upper bulge is such that the outer panel and the inner panel face each other on the sides and rear thereof. It is partially in communication with other spaces that are formed.

Therefore, the running wind introduced from the air intake opening into the space formed by the inner surface of the upwardly bulging part and the top surface of the inner panel is slightly dispersed into other spaces, and is used to cool the intercooler, etc. This has the problem of reducing the amount of air guided to the equipment, impairing the cooling effect.

(Purpose of the invention) This invention was made in order to solve the above-mentioned problems of the conventional technology. To provide a hood structure for an automobile that effectively guides running wind into an engine room without being dispersed elsewhere and improves the cooling effect.

(Structure of the invention) In order to achieve the above object, this invention has an upper bulge in a hat-shaped cross section with an opening for air intake on the front surface in order to introduce running wind into the engine room. The inner panel is provided with an opening for discharging the running wind into the engine room at a lower position corresponding to the upper bulge, and the inner panel is provided so as to surround the opening on the sides and rear of the opening. A protruding strip is formed on the inner panel, and the protruding strip protrudes toward the inner surface of the outer panel, and the protruding strip and the inner surface of the outer panel are in contact with each other via a sealing material. ing.
