Vehicle body panel securing structure
View Patent ↗A three-wheeled automobile is described herein. The automobile may include a unibody frame, a flexible engine cowling, and a fastener. The unibody frame may include an exposed unibody panel and/or a removable-panel securing fixture disposed adjacent to the exposed unibody panel. The engine cowling may be secured to the securing fixture. The fastener may pass through the engine cowling panel and may be affixed to the securing fixture, thereby securing the engine cowling panel to the unibody frame. The engine cowling panel may pass over the securing fixture and/or behind the unibody panel. The engine cowling panel may be pressed against the unibody panel outwards from the automobile by a bending force in the engine cowling panel such that the exposed unibody panel may prevent bowing of an outside edge of the engine cowling panel directly adjacent to the unibody panel.
1. A three-wheeled automobile, comprising
a unibody frame, comprising:
an exposed unibody panel; and
one or more removable-panel securing fixtures disposed adjacent to the exposed unibody panel;
a flexible engine cowling panel secured to at least one of the one or more securing fixtures; and
one or more fasteners passing through the engine cowling panel and affixed to at least one of the one or more securing fixtures,
wherein the engine cowling panel passes over the one or more securing fixtures and behind the unibody panel,
wherein an outside edge of the engine cowling panel is pressed against the unibody panel outwards from the automobile by a bending force in the engine cowling panel, and
wherein the unibody panel prevents bowing of the outside edge by exerting a counter force to the bending force on the outside edge.
2. The automobile of claim 1 , wherein the unibody panel and the flexible engine cowling panel form an engine cowling surrounding an engine compartment.
3. The automobile of claim 1 , further comprising a shape formed in the flexible engine cowling panel that is complementary to a shape of at least one of the one or more securing fixtures.
4. The automobile of claim 1 , wherein at least one of the one or more securing fixtures comprises an opening, and wherein at least one of the one or more fasteners comprises a spring-loaded detent, wherein the detent passes through the engine cowling panel and the opening and pins the engine cowling panel between the securing fixture and the fastener.
5. The automobile of claim 1 , wherein at least one of the one or more securing fixtures comprises an opening, and wherein at least one of the one or more fasteners comprises a spring-loaded detent, wherein the detent passes through the engine cowling panel and the opening and pins the engine cowling panel between the securing fixture and the fastener, and wherein the detent retracts into the fastener and rotates within the fastener to prevent the detent from engaging the securing fixture.
6. The automobile of claim 1 , wherein the unibody panel comprises a shape complementary to an engine cowling panel shape, and wherein the complementary shapes are disposed adjacent to each other and forced against each other by the bending force in the engine cowling panel.
7. The automobile of claim 1 , wherein the unibody panel comprises a hook shape complementary to an engine cowling panel hook shape, and wherein the complementary hook shapes are disposed adjacent to each other and forced against each other by the bending force in the engine cowling panel.
8. The automobile of claim 1 , wherein the unibody panel comprises a curved shape complementary to an engine cowling panel curved shape, and wherein the complementary curved shapes are disposed adjacent to each other and forced against each other by the bending force in the engine cowling panel.
9. The automobile of claim 1 , wherein the unibody panel comprises a right-angle shape complementary to an engine cowling panel right-angle shape, and wherein the complementary right-angle shapes are disposed adjacent to each other and forced against each other by the bending force in the engine cowling panel.
10. The automobile of claim 1 , wherein the unibody panel comprises a slot, and wherein the outside edge of the engine cowling panel sits in the slot.
11. The automobile of claim 1 , wherein at least one of the one or more securing fixtures comprises a standoff extended from the unibody frame.
12. The automobile of claim 1 , wherein at least one of the one or more securing fixtures comprises a threaded opening, and wherein at least one the one or more fasteners comprises a threaded rod, the threads corresponding to the threaded opening.
13. The automobile of claim 1 , wherein the outside edge of the engine cowling panel comprises an indentation corresponding to an edge of the unibody panel.
14. The automobile of claim 1 , wherein the unibody panel extends across a front of the automobile, along a side of the automobile, across a back of the automobile, across a top side of the automobile, or combinations thereof.
15. The automobile of claim 1 , wherein the unibody panel extends across a top side of the automobile between a passenger compartment and an engine compartment.
16. The automobile of claim 1 , wherein the unibody frame comprises aluminum, carbon, steel, or combinations thereof.
17. The automobile of claim 1 , wherein the engine cowling panel comprises a thermoplastic.
18. The automobile of claim 1 , wherein the engine cowling panel comprises ABS plastic.
19. The automobile of claim 1 , further comprising a flexible body panel disposed along a side of the unibody panel opposite the engine cowling panel.
20. The automobile of claim 1 , wherein the unibody panel extends from two sides of a wheel well of the automobile.
