[0029] Combination Figures 1 to 4 As shown, this embodiment proposes a rear window protection structure, including a rear bulkhead 1 and at least one guardrail 2. The rear bulkhead 1 is located between the vehicle's cabin and cargo box, and as part of the cabin's structural components, it can be used to separate the cabin and cargo box. The upper middle part of the rear bulkhead 1 has an opening 11 that extends through the vehicle's length direction. This opening 11 is suitable for installing a rear window glass 3, and after the rear window glass 3 is installed, it forms the vehicle's rear window. The guardrail 2 is located on the side of the rear bulkhead 1 closest to the cargo box and extends along the vehicle's height direction. One end of the guardrail 2 is fixedly connected to the rear bulkhead 1 on the upper side of the opening 11, and the other end is fixedly connected to the rear bulkhead 1 on the lower side of the opening 11. The fixed connection method includes, but is not limited to, bolt 123 connection or welding. In this way, not only can the upper and lower connection relationship of the rear bulkhead 1 be established through the guardrail 2, improving the overall mode of the rear bulkhead 1, but the rear window glass 3 installed at the opening 11 can also be protected on the side of the rear bulkhead 1 near the cargo box, so as to improve the protection effect of the rear window and avoid the safety of the people in the cabin due to the impact of the cargo on the rear window glass; at the same time, the overall structure is simple, the connection is convenient, and it is easy to promote and use.
[0030] For example, such as Figure 1 and Figure 2 As shown, in this embodiment, the rear bulkhead 1 is located at the rear end of the cabin and the front end of the cargo box, serving to separate cargo from passengers. The opening 11 is located in the upper middle part of the rear bulkhead 1, and the circumferential edge of the opening 11 can be used as a rear window frame. The rear window glass 3 is connected and fixed to the opening 11 by a rubber strip 4, forming a closed structure with the rear bulkhead 1, which constitutes the rear windshield of the vehicle. In this embodiment, there are two guardrails 2. The two guardrails 2 are respectively set vertically along the vehicle height direction on the side of the rear bulkhead 1 near the cargo box, and span across and connect the upper and lower sides of the opening 11 in the vehicle height direction, thereby connecting the upper and lower panels of the rear bulkhead 1 located on the upper and lower sides of the opening 11 and protecting the rear window glass 3 installed at the opening 11, thereby improving the protective effect of the rear windshield. At the same time, the two guardrails 2 are spaced apart in the vehicle width direction and symmetrical about the central axis in the vehicle width direction, which can evenly distribute the load on each guardrail 2, further improving the structural strength and impact resistance of the rear windshield protection structure.
[0031] It is understood that the guardrail 2 extends along the vehicle height direction, preferably vertically along the vehicle height direction. In other embodiments, it can also be obliquely arranged along the vehicle height direction, as long as one end of the guardrail 2 is fixedly connected to the upper side of the opening 11 and the other end is fixedly connected to the lower side of the opening 11.
[0032] It is also understandable that when there are multiple (three or more) guardrails 2 and the number of guardrails 2 is odd, one of the guardrails 2 can be centered in the vehicle width direction, and the remaining guardrails 2 can be spaced apart in the vehicle width direction and symmetrical about the central axis of the vehicle width direction; when the number of guardrails 2 is even, all the guardrails 2 are spaced apart in the vehicle width direction and symmetrical about the central axis of the vehicle width direction, so as to evenly distribute the load on each guardrail 2 and improve the impact resistance and service life of each guardrail 2.
[0033] In some embodiments, such as Figures 2 to 4As shown, the guardrail 2 includes a protective part 21, a mounting part 22, and a transition part 23 connecting the mounting part 22 and the protective part 21. The protective part 21 extends along the vehicle height direction and is mounted on the opening 11. There are two mounting parts 22, which are respectively located at both ends of the extension direction of the protective part 21 and are fixedly connected to the rear bulkhead 1. The transition part 23 is inclined from the mounting part 22 toward the protective part 21 towards the side closer to the cargo box, so that the protective part 21 is stretched relative to the mounting part 22 toward the side closer to the cargo box in the vehicle length direction, so as to form a clearance space 24 that unfolds in the vehicle length direction between the protective part 21 and the opening 11, thereby avoiding the impact on the rear window glass 3 due to the contact between the guardrail 2 and the rear window glass 3 when the cargo hits the guardrail 2, and improving the protection effect on the rear windshield. At the same time, when the protective part 21 is subjected to an impact from the side of the cargo box, it can collapse and deform toward the side where the cabin is located within the clearance space 24 to achieve the effect of collision energy absorption, further reducing the impact on the rear bulkhead 1 and the rear windshield.
[0034] In some embodiments, the guardrail 2, including the protective part 21, the mounting part 22, and the transition part 23, can be integrally formed by stamping or die casting. This not only facilitates weight reduction but also reduces the number of parts, improves assembly accuracy, and increases assembly efficiency. Simultaneously, the surface of the integrally formed part can be reinforced with mesh ribs or vertical ribs to improve appearance defects of the guardrail 2, such as shrinkage cracks, die pulls, cracks, and cold shuts, thereby increasing the pass rate of the guardrail 2.
[0035] Furthermore, such as Figure 3 and Figure 4 As shown, the protective part 21 has a clearance surface 211 and a protective surface 212 that are opposite to each other in the vehicle length direction. The protective surface 212 is convex relative to the clearance surface 211 and is located away from the cabin. This can further improve the structural strength and deformation resistance of the protective part 21 and increase the service life of the guardrail 2.
[0036] Furthermore, such as Figure 3 and Figure 4 As shown, the cross-section of the protective surface 212 after protrusion can be arc-shaped, and the two ends of the protective surface 212 in the extension direction of the protective part 21 and the avoidance surface 211 are arc-shaped. In this way, the main body of the protective part 21 is generally semi-cylindrical, and the two ends of the protective part 21 in the length direction are generally hemispherical. This can reduce the stress concentration after the protective part 21 is bent and formed, reduce local deformation, and improve the yield and structural safety of the guardrail 2.
[0037] In some embodiments, such as Figure 1 , Figure 2 and Figure 5As shown, the rear bulkhead 1 has a mounting boss 12 corresponding to the mounting part 22. The mounting boss 12 protrudes from the rear bulkhead 1 towards the side away from the cockpit. The mounting part 22 is fixedly connected to the mounting boss 12, and the connection method includes, but is not limited to, bolt 123 connection or welding. By setting the mounting boss 12, a mounting surface with a certain strength can be provided on the rear bulkhead 1 for the guardrail 2, ensuring an effective connection between the rear bulkhead 1 and the guardrail 2.
[0038] Specifically, such as Figures 1-3 as well as Figure 5 As shown, the central protrusion of the mounting boss 12 is in the shape of a flat plate and has a circular connecting hole 121 that runs through the length of the vehicle. A projection weld nut 122 is welded to the side of the connecting hole 121 near the cabin. The mounting part 22 is formed into a flat plate with a circular edge and has a circular mounting hole 221 in the center that corresponds to the connecting hole 121. In this way, by passing a bolt 123 through the mounting hole 221 and the connecting hole 121 and connecting it to the projection weld nut 122, the mounting part 22 and the mounting boss 12 can be fixedly connected, so that the guardrail 2 and the rear panel 1 are firmly and effectively connected together.
[0039] Furthermore, such as Figure 2 As shown, a waterproof gasket 124 is provided between the mounting hole 221 and the connection hole 121. The waterproof gasket 124 can improve the waterproof performance of the bolt 123 connection and prevent rainwater from entering the cabin through the bolt 123.
[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the circumferential edge of the opening 11 can also be recessed along the length of the vehicle towards the side closest to the passenger compartment. The rear window 3 is then connected to the recessed side and covers the opening 11. The rear window 3 is then connected and fixed to the circumferential edge of the opening 11 using connectors such as adhesive strips 4, forming the vehicle's rear windshield. This further expands the clearance space 24 between the guardrail 2 and the rear window 3, improving collision energy absorption; or, without modifying the specific structure of the guardrail 2, it creates a clearance space 24 between the guardrail 2 and the rear window 3, achieving the goal of avoiding interference contact between the guardrail 2 and the rear window 3.
[0041] It is understood that in other embodiments, the rear window glass 3 and the opening 11 can also be connected together by a stop snap-fit, and then the rear window glass 3 and the circumferential edge of the opening 11 can be connected and fixed by adhesives, etc. The specific connection method is not limited.
[0042] In some embodiments, such as Figure 2 and Figure 6As shown, the rear windshield protection structure also includes a reinforcing plate 5, which extends along the width of the vehicle and is located on the side of the rear bulkhead 1 closest to the passenger compartment, below the opening 11. The reinforcing plate 5 has a circumferentially extending edge welded to the rear bulkhead 1, and its central portion protrudes from the rear bulkhead 1 towards the side furthest from the cargo box. Thus, the reinforcing plate 5 strengthens the structural strength of the lower part of the rear bulkhead 1, improving its resistance to deformation. Preferably, the reinforcing plate 5 is positioned on the lower side of the opening 11 corresponding to the fixing connection point of the mounting boss 12 or the guardrail 2 located below the opening 11, so that its protruding portion covers the fixing connection point between the mounting boss 12 or the guardrail 2 and the lower side of the rear bulkhead 1, thereby avoiding the safety hazard of exposed and protruding welded nuts 122 or bolts 123 inside the passenger compartment.
[0043] Furthermore, in another embodiment, a vehicle is proposed that includes the rear window protection structure described in the above embodiments. For other structures and working principles of the rear window protection structure, please refer to the above description of the embodiments of the rear window protection structure; for other vehicle structures, please refer to the prior art; since the rear window protection structure has the aforementioned technical effects, the vehicle having this rear window protection structure should also have corresponding technical effects, which will not be elaborated further here.
[0044] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
