DETAILED DESCRIPTION

(9) FIG. 1 illustrates a side view of a vehicle 10 of the type typically described as a side-by-side all-terrain vehicle. The vehicle 10 may include a frame 12, such as a tubular welded frame, and a body 14, which may be constructed from a number of plastic, steel, aluminum, or composite body panels, that are attached to the frame 12. The vehicle 10 is powered by an engine 16, which in the embodiment illustrated herein, is located below longitudinally rearward of the vehicle cabin 18 where the driver and a passenger may be seated during operation of the vehicle 10. The engine 16 operates to rotate wheels 28, which include tires 26, that are located in wheel wells 24 of the vehicle 10.

(10) FIG. 2 illustrates a close up view of a portion of the electrical system 20 that provides electrical power to the engine 16. The typical engine 16 includes a plurality of cylinders (not shown), and the electrical system 20 of the vehicle 10 may include an electronic control unit (ECU) (not shown) to distribute electrical power to each of the cylinders of the engine 16. In order to maintain constant voltage across the ECU, the vehicle 10 may be equipped with a regulator 22. The regulator 22 maintains constant voltage application across the ECU, but is susceptible to overheating and needs to be cooled. In the embodiment illustrated, the regulator 22 for the electrical system 20 is located in a wheel well 24 of the vehicle 10. The regulator 22 is located in a left rear wheel well 30 in the embodiment illustrated in FIG. 1, although this positioning could be in any wheel well 24 on the vehicle 10 based on the preferred engine 16 location and layout as dictated by the design of the vehicle 10.

(11) However, due to its location in the wheel well 24, the regulator 22 is further susceptible to damage from debris thrown by a tire 26 on the wheel 28 disposed in the wheel well 24. Therefore, as shown in FIG. 3, a cover 32 may be applied to protect the regulator 22 from debris. The cover 32 is designed to be substantially concave to cover the regulator 22.

(12) As additionally illustrated in FIG. 4, which is a bottom view of the cover 32, the cover 32 further may include an outer edge 34 that is designed to match a corresponding surface 36 of the interior 38 of the wheel well 24, the left rear wheel well 30 in the illustrated embodiment. The cover 32 may be attached to the corresponding surface 36 of the interior 38 of the wheel well 24 by any suitable fasteners 40, such as nut and bolt fasteners, screws, rivets, welds, and the like. The cover 32 may be constructed of plastic, steel, stainless steel, aluminum, or any other suitable material.

(13) The cover 32 may also include an outlet 42 to enable the passage of cooling air over and away from the regulator 22 during operation of the vehicle 10. The vented areas 42 are positioned such that debris thrown by the tire 26 or wheel 28 disposed in the wheel well 24 does not enter the cover 32 and damage the regulator 22 during normal operation of the vehicle 10.

(14) FIGS. 5-7 illustrate a system for supplying the regulator 22 with fresh airflow (represented by arrows for illustration purposes and labeled AF in FIGS. 5-7) from outside of the vehicle 10 for cooling the regulator 22 to ensure its continued operation as intended. In the vehicle 10 illustrated in FIGS. 5-7, in which the engine 16 is located vertically below and longitudinally rearward of the cabin 18, the body 14, directly longitudinally rearward of a door 44 to the cabin 18, may include an air intake 46. The air intake 46 may be formed integrally within the body 14, and may further include a mesh covering 48 to prevent the intake of large debris, such as rocks, sticks, branches, twigs, and the like.

(15) As the vehicle 10 is moving, airflow AF is directed into the air intake 46 as illustrated in FIGS. 5-6, and passes over the regulator 22 as illustrated in FIG. 7. In order to facilitate cooling of the regulator 22, warm airflow AF is then passed out through the vented areas 42, as illustrated in FIG. 4. The location of the outlet 42 also ensures that debris does not collect in the cover 32, but rather passes out into the wheel well 24.

The appearances of the phrase in one embodiment or an embodiment in various places in the specification are not necessarily all referring to the same embodiment.
