Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an extended tail rail of a truck bucket. Background Art

[0002] UTV (Utility Vehicle) is commonly known as a mountain off-road vehicle. It is generally equipped with a small truck bed at the rear and is a multi-purpose small vehicle shaped like a pickup truck. The truck bed of a UTV model is limited by the size of the entire vehicle, so the cargo area of ​​the truck bed is very limited. In view of this, there are currently some truck bed extension tail rails specially adapted for UTV models on the market. The tailgate extender system disclosed in patent application CN101132948A can be referred to. It is mainly used in pickup trucks. When in use, the tailgate of the car needs to be laid flat to provide an installation environment, and then the newly added truck bed extension tail rail is installed on the tailgate (generally bolts are used as fasteners). The extended length of the truck bed is actually the original height of the tailgate, which at least increases the cargo length of the truck bed by tens of centimeters. Since the above-mentioned extended tail rail of the truck bed needs to act as a guardrail, it is inevitable to use fasteners such as bolts. After loading, if the user needs to restore the tailgate, he can only remove all the fasteners on the extended tail rail of the truck bed first, then remove the entire extended tail rail from the truck bed, and finally close the tailgate again, which is very inconvenient. Utility Model Content

[0003] In view of the above problems, the utility model proposes a truck bed with an extended tail rail, which mainly solves the problems of the background technology.

[0004] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the content of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all the contents.

[0020] This embodiment proposes a truck bed extension tail rail, such as Figure 1 As shown, it includes mirror-symmetrically arranged mounting columns 1, which are used to be installed on both sides of the rear end of the target truck bucket. Horizontal first hinges 2 are arranged in the center of the opposite sides of the two mounting columns 1, and the two first hinges 2 are coaxially arranged. The two ends of the guardrail assembly 3 are hinged to the two mounting columns 1 through the two first hinges 2 respectively.

[0021] In this embodiment, by setting the first hinge 2 in the middle of the two mounting columns 1, and hinge the two ends of the guardrail assembly 3 with the two mounting columns 1 through the two first hinges 2, the guardrail assembly 3 is provided with a flip function. If the user needs to close the tailgate of the truck bucket, he only needs to flip the entire guardrail assembly 3 180° toward the front of the vehicle with the first hinge 2 as the rotation axis, and put the guardrail assembly 3 into the truck bucket. After the interference of the guardrail assembly 3 is lost, the tailgate of the truck bucket can be closed normally. In addition, the flipped guardrail assembly 3 also plays the role of dividing the truck bucket space. The user can place items in different areas in the truck bucket with the guardrail assembly 3 as the boundary.

[0022] Specifically, the effect after the extension tail rail of the truck bed is installed is as follows Figure 3 As shown, two mounting posts 1 are first installed on both sides of the rear of the truck 100, and then the two ends of the guardrail assembly 3 are respectively hinged to the two mounting posts 1 through two first hinges 2. The effect of the guardrail assembly 3 after flipping is as shown in FIG. Figure 4 As shown, at this time, the guardrail assembly 3 enters the middle part of the vehicle bucket 100.

[0023] The guardrail assembly 3 is any three-sided structure that can achieve the function of closing the rear of the truck bed. This embodiment provides one example, such as Figure 1 and 2 As shown, the guardrail assembly 3 includes a main rail 31 and side rails 32 vertically mounted on both sides of the main rail 31, and the middle of the side rails 32 is hinged to the corresponding mounting column 1 through the first hinge 2. In this solution, the side rails 32 are the part of the entire guardrail assembly 3 connected to the mounting column 1, and the middle of the side rails 32 is selected as the connection point of the first hinge 2, so as to ensure that the guardrail assembly 3 can still be placed flat in the truck bed after being turned over.

[0024] In order to improve the use scenarios of the extended tail rail of the truck bed, it is more preferred that the main rail 31 includes two symmetrically arranged sub-rails 311, each sub-rail 311 is hinged to the adjacent side rail 32 through the second hinge 4, and the rotation axis of the second hinge 4 is vertically arranged. In this solution, the main rail 31 is divided into two split sub-rails 311, and the sub-rails 311 are installed on the side rails 32 through the second hinge 4. The two sub-rails 311 are opened outward to facilitate the loading and unloading of goods in the truck bed. Furthermore, a fixing member (not shown in the figure) is provided between the two sub-rails 311, and the fixing member can be an ordinary latch bolt, or a rotary bolt, which can fix the two sub-rails 311 on the same vertical horizontal plane. No special requirements.

[0025] The above-mentioned mounting column 1 is designed according to the curvature of the two inner sides of the target truck bed, and the mounting column 1 is generally fixed by bolts. In one example, the bottom of the mounting column 1 is also provided with a mounting ear 5, which is an extension of the mounting column 1 and is used to fix the bottom of the mounting column 1 to the surface of the truck bed, thereby improving the fixing effect of the mounting column 1. More preferably, the side rail 32 has no contact with the mounting ear 5. This design method takes into account the flipping action of the side rail 32. Therefore, the side rail 32 is suspended above the mounting ear 5, which can effectively prevent the bottom of the side rail 32 from interfering with the mounting ear 5 or the surface of the truck bed when the guardrail assembly 3 flips.

[0026] In this embodiment, the guardrail assembly 3 should be perpendicular to the truck bed after installation, and because the guardrail assembly 3 needs to be flipped, it is not suitable to be placed directly at the rear of the truck bed. In a preferred embodiment, buffer feet 6 are provided at the bottom and top of the side rail 32, and the side rail 32 indirectly contacts the truck bed through the buffer feet 6.

[0027] In addition, since the guardrail assembly 3 can rotate freely along the first hinge 2 in the above scheme, a quick locking mechanism 8 is provided at the lower part of the main rail 31, and the lower part of the main rail 31 is fixed to the truck bed through the quick locking mechanism 8, which is used to fix the entire guardrail assembly 3 to prevent the guardrail assembly 3 from being bumped back and forth against the truck bed during the driving of the vehicle.

[0028] Optionally, a limiting member 7 is provided on one side of the sidebar 32 close to the adjacent sub-bar 311, and the limiting member 7 abuts against the inner side of the sub-bar 311. When closing the sub-bar 311, the user needs to push the two sub-bars 311 towards each other to rotate and close. When the sub-bar 311 hits the limiting member 7, it indicates that it has been closed in place.

[0029] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the essence of the content of the utility model should be included in the protection scope of the utility model.
