Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and in particular, to an engine hood latch structure and a vehicle. Background Art

[0002] Currently, for an independent adjustable engine hood latch structure, one end of the latch ring is threadedly connected to the bottom plate, and the other end is in interference fit connection with the bottom plate through a through hole, as Figure 1 shown.

[0029] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of the engine hood latch structure provided by an embodiment of this application. The engine hood latch structure 100 includes a bottom plate 10, a latch ring 20, a first spacer 30 and a second spacer 40;

[0030] The bottom plate 10 is relatively provided with a first mounting hole 11 and a second mounting hole 12. The first spacer 30 and the second spacer 40 are both located on the first surface of the bottom plate 10, and the first spacer 30 covers the first mounting hole 11, and the second spacer 40 covers the second mounting hole 12;

[0031] The latch ring 20 has a U-shaped structure. The U-shaped structure faces the second surface of the bottom plate 10. The first end of the U-shaped structure is connected to the first spacer 30, and the second end of the U-shaped structure is connected to the second spacer 40;

[0032] The first spacer 30 is used to isolate the first end of the U-shaped structure from the air, and the second spacer 40 is used to isolate the second end of the U-shaped structure from the air.

[0033] It should be understood that in the related art, both ends of the latch ring 20 are connected to the bottom plate 10 through the first mounting hole 11 and the second mounting hole 12 provided on the bottom plate 10 to enclose a ring structure, as Figure 1 shown. With the use of the vehicle, the through-hole end of the latch ring 20 and the bottom plate 10, and the threaded connection end and the riveting nut will become loose and rub, resulting in the damage of the corrosion-resistant coating. Especially in a humid environment, the through-hole end is prone to rust due to the damage of the coating, and the top of the riveting nut is prone to rust due to the leakage of water through the thread gap.

[0034] It should be understood that in specific implementation, the first end of the buckle ring 20 in this embodiment corresponds to the end where the buckle ring 20 is in threaded fit with the riveting nut in the related art, and the second end of the buckle ring 20 corresponds to the through-hole end of the buckle ring 20 in the related art, and this end is in interference fit with the bottom plate 10.

[0035] In this way, in the embodiment of the present application, by respectively arranging the first isolation member 30 and the second isolation member 40 at the first mounting hole 11 and the second mounting hole 12 of the bottom plate 10, when the buckle ring 20 is fixed to the bottom plate 10 through the first mounting hole 11 and the second mounting hole 12, both ends of the buckle ring 20 are isolated from the air, so as to reduce the risk of rust, and further improve the service performance.

[0036] Optionally, the first isolation member 30 includes a first mounting plate 31 and an extension portion 32;

[0037] The first mounting plate 31 is arranged on the first surface of the bottom plate 10, and the extension portion 32 extends from the first mounting plate 31 through the first mounting hole 11 away from the first surface of the bottom plate 10;

[0038] The first end of the U-shaped structure is connected to the extension portion 32.

[0039] In this embodiment, by arranging the first mounting plate 31 to cover the first mounting hole 11, moisture is isolated from entering the first mounting hole 11, and the corrosion resistance is improved.

[0040] Optionally, the first isolation member 30 further includes a gasket 33, and the gasket 33 is located between the first mounting plate 31 and the bottom plate 10;

[0041] The gasket 33 is provided with a third mounting hole, and the extension portion 32 sequentially passes through the third mounting hole, the first mounting hole 11 and is connected to the bottom plate 10.

[0042] In this embodiment, by arranging the gasket 33 between the first mounting plate 31 and the bottom plate 10, the damping effect between the two can be improved.

[0043] Optionally, the extension portion 32 has a first through hole 321, the first mounting plate 31 covers the first end of the first through hole 321, the first end of the U-shaped structure is located in the first through hole 321, and there is a first gap 50 between the first end of the U-shaped structure and the first mounting plate 31.

[0044] It should be understood that in specific implementation, the extension portion 32 should have a certain length to wrap the first end of the buckle ring 10, so as to further reduce the risk of rust.

[0045] In addition, by setting the first gap 50, the height adjustment between the U-shaped structure and the bottom plate 10 can be achieved.

[0046] Optionally, the height of the first end of the U-shaped structure is lower than the height of the second end of the U-shaped structure.

[0047] Optionally, the second spacer 40 has a third mounting hole 41, and the second end of the U-shaped structure is connected to the second spacer 40 through the third mounting hole 41;

[0048] There is a second gap 60 between the second end of the U-shaped structure and the bottom of the third mounting hole 41.

[0049] It should be understood that in the specific implementation, by setting the second gap 60, the height adjustment between the U-shaped structure and the bottom plate 10 can be achieved.

[0050] In the specific implementation, the first spacer 30 can be arranged on the opposite two sides of the bottom plate 10 to wrap the first mounting hole 11. The second end of the locking ring 20 can only enter the second mounting hole 12 of the bottom plate 10 through the third mounting hole 41 and be connected to the bottom plate 10, thereby further reducing the risk of rust.

[0051] Optionally, the aperture of the third mounting hole 41 is smaller than the aperture of the second mounting hole 12.

[0052] Optionally, the first spacer 30 is a non-through riveting nut.

[0053] In this embodiment, by setting the non-through riveting nut, the top thread gap is not exposed, thereby isolating moisture from entering the thread gap and improving the corrosion resistance.

[0054] In addition, the thread engagement dimension can be increased to ensure the connection strength between the locking ring 20 and the bottom plate 10.

[0055] Optionally, the second spacer 40 and the bottom plate 10 are connected by a two-shot injection molding process.

[0056] In this embodiment, by setting the second spacer 40 and the bottom plate 10 to be connected by a two-shot injection molding process, the connection tightness between the two can be improved.

[0057] In another alternative embodiment, this isolation structure can also be tightly connected to the bottom plate 10 through a hard rubber vulcanization process.

[0058] In a second aspect, an embodiment of the present application provides a vehicle, including an engine hood, and further including the engine hood locking structure 100 as described above;

[0059] The bottom plate 10 of the engine hood locking structure 100 is arranged on the engine hood.

[0060] Since the technical solution of this embodiment includes all the technical solutions of the above embodiment, it can at least achieve all the technical effects of the above embodiment, and will not be elaborated here one by one.

[0061] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
