Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a cargo box cover and a pickup truck. Background Technology
[0002] As an important component added to commercial pickup trucks, the cargo box cover effectively fulfills its purpose in scenarios where the dryness of the carried goods is crucial. Currently, pickup trucks with cargo box covers come in two types: roll-up and flip-top. However, roll-up cargo box covers take up too much space when the roll-up cover is folded up, significantly reducing the usable space inside the cargo box. Therefore, flip-top cargo box covers are now more commonly used.
[0003] The flip-top cargo box cover is mainly a one-time flip, that is, the entire cargo box cover flips, and the flip angle cannot be opened to 90 degrees or even greater. This also reduces the usable space of the cargo box. In order to solve the above problems, a cargo box cover that can be flipped twice has emerged (announcement number CN216685819U). It is equipped with two cover plate elements and the two cover plate elements are hinged together, so that one or multiple cover plate elements can be flipped as needed to achieve multiple states of opening and closing.
[0004] Existing cargo box lids that can be flipped twice are only connected to adjacent lid components by hinges, without any assistance or cushioning. When opening or closing the cargo box lid, users need to lift or lower the lid components by their own strength, which is laborious, difficult, and unsafe. In addition, when transporting large items, the flipped cargo box lid cannot be fully closed, and the transported items cannot be secured, resulting in the items being unable to be transported, which is a great waste of resources. Utility Model Content
[0005] To address the technical problems of existing reversible cargo box covers mentioned above, where adjacent cover elements are only connected by hinges, lacking assistance and cushioning capabilities, making opening and closing laborious and difficult, and resulting in low safety, this utility model provides a cargo box cover.
[0006] The technical solution of this utility model is as follows:
[0007] This utility model provides a cargo box cover, including a cover frame, a first cover unit flipped and connected to the cover frame, and a second cover unit flipped and connected to the first cover unit. The first and second cover units are arranged sequentially along the length of the cover frame. An assist buffer unit is connected between the first and second cover units, realizing the segmented opening and closing of the cargo box cover. During use, it can be operated flexibly according to actual needs. For example, only the second cover unit needs to be opened to easily access the goods near the rear of the vehicle without opening the entire cargo box cover, which improves the convenience of use. The assist buffer unit provides assistance and cushioning for the opening and closing of the cover units, reducing the operational burden, reducing the impact force when the cover is opened and closed, reducing noise, and protecting the cover and vehicle components.
[0008] Preferably, the front end of the first cover unit is flipped and connected to the cover frame via a first hinge, and the rear end of the first cover unit is flipped and connected to the second cover unit via a second hinge. The first hinge allows the first cover unit to rotate flexibly relative to the cover frame, and the second hinge allows the second cover unit to rotate relative to the first cover unit, ensuring the normal operation of each cover unit in different operating scenarios. The overall structure is simple, reliable, and easy to maintain.
[0009] Preferably, a second mounting bracket is fixedly provided on the lid frame, and a first hinge is fixedly installed on the first lid unit, with the first hinge rotatably connected to the second mounting bracket; a third mounting bracket is fixedly provided on the lower rear surface of the first lid unit, and a second hinge is fixedly installed on the front end of the second lid, with the second hinge rotatably connected to the third mounting bracket. The mounting bracket provides a stable mounting base for the hinge, enhances the stability of the connection between the hinge and the lid unit and lid frame, and ensures that the hinge will not loosen or shift due to force during frequent opening and closing of the lid, thereby ensuring the normal use of the entire cargo lid and extending its service life.
[0010] Preferably, a fourth mounting bracket is fixedly provided on the lower rear surface of the first lid unit, and a fifth mounting bracket is fixedly provided on the lower rear surface of the second lid unit. The fourth and fifth mounting brackets are connected by an assist buffer unit. The two ends of the assist buffer unit are respectively hinged to the fifth and fourth mounting brackets. The mounting brackets provide reliable connection points for the assist buffer unit, enabling the assist buffer unit to function effectively. Through the hinged connection, the assist buffer unit can flexibly adapt to angle changes during the opening and closing of the lid, stably providing assistance and buffering, and improving the smoothness and safety of the lid opening and closing.
[0011] Preferably, the assisting and buffering unit is a pneumatic support rod, which can provide a stable and lasting assisting and buffering effect. There are two assisting and buffering units, which are arranged opposite each other along the width direction of the lid frame. They can act evenly between the first lid unit and the second lid unit, ensuring that the lid is subjected to uniform force during opening and closing, and there will be no tilting or jamming, further improving the stability and convenience of operation.
[0012] Preferably, a first sealing strip is provided between the periphery of the first and second lid units and the lid frame to prevent dust, rainwater, etc. from entering the cargo box from the connection between the lid unit and the lid frame. A second sealing strip is fixedly provided on the outer periphery of the lid frame to strengthen the isolation between the lid frame and the outside world. A third sealing strip is fixedly provided at the front end face of the second lid unit, and a fourth sealing strip is fixedly provided on the lower surface of the rear end of the second lid unit.

[0042] Understandably, in actual use, lighting structures can also be installed on the cargo box lid for nighttime use. The specific settings can be configured according to actual needs, and no further restrictions will be imposed here.
[0043] The specific working principle is as follows:
[0044] When closing the cargo box lid, such as Figure 1 As shown, the first box cover unit 2 and the box cover frame 1 do not flip each other, and the first box cover unit 2 and the second box cover unit 3 do not flip each other. At this time, the second box cover unit 3 is locked to the vehicle body through the lock body 21.
[0045] When the cargo box lid is opened to the first stage, such as Figure 7 As shown, the first lid unit 2 does not flip with the lid frame 1, while the second lid unit 3 flips with the first lid unit 2. At this time, the operator unlocks the lock body 21 by using the handle 25 and lifts the second lid unit 3. The second lid unit 3 flips around the second hinge 18 to partially open the cargo box lid. Similarly, when it is necessary to close the second lid unit 3, it is only necessary to flip the second lid unit 3 in the opposite direction. During the flipping process of the second lid unit 3, the assist buffer unit 20 provides assistance to reduce the difficulty of opening and closing the second lid unit 3 and improve the safety of use.
[0046] When the cargo box lid is opened in a secondary manner, such as Figure 8 As shown, the first lid unit 2 flips with the lid frame 1, and at the same time, the second lid unit 3 flips with the first lid unit 2. At this time, the second lid unit 3 and the first lid unit 2 are supported by the auxiliary buffer unit 20, which has the ability to prevent falling, so as to ensure the stability and safety of the cargo box lid during the opening process. The secondary opening angle of the cargo box lid is greater than 90°, which can make full use of the cargo box space at the rear of the pickup truck.
