The embodiment of the application provides a protection structure (hereinafter referred to as protection structure) penetrating through a tail lamp 100 and a lifting tail wing 200, which aims to reduce the action stress of a wing plate 201 on a top wall 101 penetrating through the tail lamp 100 when the wing plate 201 of the lifting tail wing 200 descends to a closed state, further reduce the probability of cracking of the top wall 101 penetrating through the tail lamp 100 under the extrusion of the wing plate 201, and can better protect the penetrating through tail lamp 100. Accordingly, the protection structure will be applied to the tail gate assembly 300 (i.e. the assembly of the automobile parts, the tail gate assembly 300 may be used as an automobile part, may be purchased from a supplier, may be self-assembled, and may be transported to an automobile assembly shop after being assembled in a tail gate shop), and the assembled tail gate assembly 300 is used for assembly of the automobile 400 (i.e. whole automobile production).

In the tail gate assembly 300, the through tail light 100 and the lift tail 200 are mounted on the tail gate 301, and the lift tail 200 includes the wing panel 201, and the wing panel 201 has a closed state with respect to the tail gate 301 and an open state for lifting use.

When the automobile runs at a high speed, according to the aerodynamic principle, air resistance is encountered in the running process of the automobile, and aerodynamic quantities such as longitudinal acting force (acting force in the direction opposite to the advancing direction of the automobile), lateral acting force, vertical lifting acting force and the like are simultaneously generated around the center of gravity of the automobile. In order to effectively reduce and overcome the influence of air resistance received during high-speed running of the automobile, therefore, the wing plate 201 of the lifting tail wing 200 is driven by the lifting mechanism 202 to be lifted to be in an open state in the running process of the automobile, and the wing plate 201 can enable air to generate fourth acting force on the automobile, namely, the automobile can generate larger adhesive force on the ground, so that a part of vertical lifting acting force can be counteracted, the automobile is effectively controlled to float upwards, the wind resistance coefficient is correspondingly reduced, the automobile can be tightly attached to the road ground to run, and the running stability of the automobile is improved.

When the automobile is parked, the wing plate 201 of the lifting tail 200 is driven by the lifting mechanism 202 to descend to a closed state, as shown in fig. 4, the upper surface of the wing plate 201 is flush and flat with the upper surface of the automobile tail door 301, that is, the lifting tail 200 is basically hidden when the automobile is parked.

As shown in fig. 1 to 3, the protection structure includes at least one protection connection 10. As shown in fig. 3, the protection connector 10 includes a body 13, a first connection end 11 and a second connection end 12, and the first connection end 11 and the second connection end 12 are connected to the body 13. As shown in fig. 1 and 2, the first connecting end 11 is connected to the top wall 101 penetrating the tail lamp 100, and the connecting position between the second connecting end 12 and the body 13 is provided with a breakable structure 14. The design of the frangible structure 14 of the protection connector 10 is such that the protection connector 10 has a certain supporting strength and the frangible structure 14 is susceptible to breaking when subjected to forces exceeding the limit. The second connecting end 12 protrudes through the surface of the top wall 101 of the tail lamp 100, and the second connecting end 12 is used for bearing the pressing stress exerted by the wing plate 201 when the wing plate 201 moves downwards to the closed state.

When the automobile is stopped and the wing plate 201 of the lifting tail wing 200 is driven by the lifting mechanism 202 to descend to a closed state, the wing plate 201 applies extrusion stress to the second connecting end 12 of the protection connecting piece 10, and the extrusion stress is transmitted to the top wall 101 penetrating through the tail lamp 100 by the protection connecting piece 10. In this protection structure, since the protection connector 10 is provided with the frangible structure 14, when the compressive stress applied by the wing plate 201 to the second connection end 12 of the protection connector 10 exceeds the limit stress value that can be borne by the frangible structure 14 of the protection connector 10, the compressive stress will break the frangible structure 14 of the protection connector 10, so that the protection connector 10 breaks the force transmission, and the compressive stress is not transmitted to the top wall 101 penetrating the tail lamp 100 any more, so that the top wall 101 penetrating the tail lamp 100 is protected from being broken by the downward movement of the wing plate 201.

As shown in fig. 1 and 2, an embedded nut 102 is provided through the top wall 101 of the tail lamp 100, and the first connection end 11 of the protection connector 10 is detachably connected to the embedded nut 102 by a screw 16. When the frangible structure 14 of the protection connector 10 breaks, the first connection end 11 remaining on the top wall 101 of the tail lamp 100 can be detached by unscrewing the screw 16 and then replaced with a new protection connector 10. And, embedded nut 102 can realize dismantling, installation many times, realizes the cyclic utilization, improves the durable degree that runs through roof 101 of tail lamp 100 to the life that runs through tail lamp 100 has been improved.

As shown in fig. 1, the protective structure further comprises a protective panel 20. The protection panel 20 is connected to the second connection end 12 of the protection connection member 10, and the protection panel 20 contacts the wing 201 when the wing 201 is moved down to the closed state. When the wing plate 201 moves down to the closed state, the pressing stress is applied to the protection panel 20, and in turn, the protection panel 20 transmits the pressing stress to the second connection end 12 of the protection connector 10 and along the protection connector 10 to the top wall 101 penetrating the tail lamp 100. When the compressive stress is transmitted through the frangible structure 14 of the protection connector 10, the compressive stress will fracture the frangible structure 14 of the protection connector 10 when exceeding the limit force value that the frangible structure 14 of the protection connector 10 can withstand, thereby breaking the force transmission of the protection connector 10, the compressive stress will not be transmitted to the top wall 101 of the through-taillight 100 any more, thereby protecting the top wall 101 of the through-taillight 100 from being crushed by the descending wing plate 201.

Further, the second connection end 12 of the protection connector 10 and the protection panel 20 are detachably mounted. Therefore, when the breakable structure 14 of the protection connector 10 breaks (i.e. the protection connector 10 fails), the protection panel 20 can be reinstalled on the top wall 101 of the through taillight 100 by replacing the protection connector 10 with a new one, thereby completing maintenance and greatly reducing maintenance cost.

In an embodiment of the present application, as shown in fig. 1 and 2, the protection structure further includes an adapter 30. The adapter 30 has a first end and a second end, i.e., a first end 31 of the adapter and a second end 32 of the adapter, as shown in FIG. 2. The first end 31 of the adapter is connected to the second connection end 12 of the protection connection 10. The first end 31 of the adaptor and the second connecting end 12 of the protection connecting piece 10 may be fixedly connected, for example, welded, into a whole (the adaptor 30, whether a plastic piece or a metal piece, may be welded to the second connecting end 12 of the protection connecting piece 10 by means of hot melting); alternatively, the first end 31 of the adaptor and the second connecting end 12 of the protection connector 10 may be connected by a detachable connection, for example, by a bolt-nut pair, and further, for example, by a snap-fit structure. The second end 32 of the adapter is connected to the protection panel 20, and the second end 32 of the adapter is connected to the protection panel 20 in a detachable manner, for example, by a bolt-nut pair, and is also connected to each other by a snap structure, and is further connected by a ball joint hinge.

In assembling the through-taillight 100 and the protection panel 20, the through-taillight 100 is mounted on the automobile tail door 301, the first connection end 11 of the protection connector 10 is locked on the top wall 101 of the through-taillight 100 by the screw 16, and then the first end 31 of the adaptor is connected to the second connection end 12 of the protection connector 10 (in the embodiment of the present application, the first end 31 of the adaptor and the second connection end 12 of the protection connector 10 are preferably connected in a detachable connection manner), and then the protection panel 20 is mounted on the second end 32 of the adaptor.

In addition, the protection panel 20 can be mounted or dismounted only by opening the wing 201 without interfering with the wing 201 of the lifting tail 200 during the assembly process of the protection panel 20. The assembled protective panel 20 does not interfere with the assembly of the elevating fin 200, and the wing 201 of the elevating fin 200 and the elevating mechanism 202 can be detached or attached after the assembly of the protective panel 20 is completed.

The second connection end 12 of the protection connector 10 is connected to the protection panel 20 via the adapter 30, and after the frangible structure 14 of the protection connector 10 breaks, a maintenance person can easily and quickly detach the protection panel 20 from the top wall 101 penetrating the tail lamp 100, and can easily detach the first connection end 11 remaining after breaking and penetrating the top wall 101 of the tail lamp 100. Then, the maintenance personnel can replace the damaged protection connecting piece 10 with a new one, and reinstallate the protection panel 20, thus the maintenance work can be completed, and the maintenance work is convenient and quick.

In other embodiments of the present application, the second end 32 of the adapter is fixedly coupled to the protective panel 20, such as by welding. That is, the protective panel 20 is fixedly coupled to the second end 32 of the adapter at the first end 31 of the adapter coupled to the second coupling end 12 of the protective coupling 10. At this time, after the breakage of the breakable structure 14 of the protection connector 10, the protection panel 20, all the adapters 30, and all the protection connectors 10 need to be replaced.
