However, the present application can be implemented in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0037] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate relative importance or implicitly specify the quantity of the technical features indicated. Therefore, unless otherwise specified, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features; "plurality" means two or more. The term "comprising" and any variations thereof are intended to be non-exclusive inclusion, and one or more other features, integers, steps, operations, units, components, and / or combinations thereof may be present or added.

They are merely simplified descriptions for the convenience of describing the present application, and do not indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0039] Furthermore, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0040] Currently, most pickup truck tonneau covers are constructed of cold-pressed steel, fiberglass, and aluminum alloy to ensure strength. However, these metal covers are heavy, making them difficult to transport and install, especially those with one-piece, non-detachable structures. Furthermore, the aesthetics of the tonneau cover surface needs to be improved. Even with paint or film applied to the tonneau cover, since the tonneau cover is generally exposed to the external environment, the surface film will be affected over time, reducing the tonneau cover's aesthetics.

[0041] Based on this, the embodiment of the present application provides a pickup truck box cover, such as Figure 1As shown, the pickup truck compartment cover 10 includes a cover body 100 and a support assembly 110 . The cover body 100 is an integral structure, and the cover body 100 is a carbon fiber material structure. The support assembly 110 is arranged inside the cover body 100 to support the cover body 100 .

[0042] Compared to traditional metal and rigid plastic, carbon fiber materials are lighter in weight. The embodiment of the present application utilizes a carbon fiber cover 100, which is also a one-piece structure. This reduces the overall mass of the cover 100, making it easier to install and carry. Furthermore, considering the insufficient strength of carbon fiber materials, the embodiment of the present application also incorporates a support assembly within the pickup truck tonneau cover to support the cover 100 and prevent deformation. Furthermore, the support assembly 110 is located within the cover 100, concealing it from view and preventing it from being seen by the user. This enhances the overall integrity of the pickup truck tonneau cover 10, thereby improving its aesthetic appeal.

[0043] In addition, compared with the solution of adding a hard plastic bottom cover at the bottom of the carbon fiber cover to prevent the surface carbon fiber cover from deforming, in the embodiment of the present application, since the cover body 100 is an integrated structure, no matter what the ambient temperature of the pickup truck box cover 10 is, all parts of the cover body 100 are in the same degree of thermal expansion and contraction, so there will be no problems of deformation or falling off caused by different expansion degrees due to inconsistent materials of the inner and outer layers of the cover body 100, thereby ensuring the stability of the cover body 100.

[0044] It should be noted that "the cover 100 is a one-piece structure, and the cover 100 is a carbon fiber material structure" means that the cover 100 is basically composed of carbon fiber material without the need for secondary processing or splicing. This can mean that the carbon fiber material is directly used to form the cover 100 using technologies such as injection molding and 3D printing, or it can mean that the cover 100 is formed by laminating carbon fiber films layer by layer, so that after the cover 100 is formed, the cover 100 appears to the human eye as a single, integral, and inseparable structure, and no splicing marks can be seen on the cover 100. Specifically, when the design of the cover 100 is formed by laminating carbon fiber films layer by layer, the cover 100 is mainly composed of carbon fiber. However, in the actual production of the cover 100, there will be a colloid between the carbon fiber films for bonding the carbon fiber films, and a small amount of glass fiber or toughness material will be added between the carbon fiber films to ensure the strength and stability of the cover 100. This does not affect the definition of a carbon fiber material structure. Therefore, it is understood that a carbon fiber material structure does not specifically refer to a structure made of 100% pure carbon fiber material.

[0045] It should be noted that "the support assembly 110 is disposed inside the cover body 100" means that the support assembly 110 is embedded inside the cover body 100 during the manufacturing process of the cover body 100, so that the support assembly 110 is not exposed outside the cover body 100. Moreover, disposing the support assembly 110 inside the cover body 100 does not affect the definition of the cover body 100 as a one-piece structure, because the support assembly 110 is added to the cover body 100 during the manufacturing process, similar to secondary injection molding, and the support assembly 110 and the cover body 100 cannot be separated. The cover body 100 ultimately still looks like a one-piece structure as a whole, and therefore does not affect the definition of the cover body 100 as a one-piece structure.

[0046] In the embodiment of the present application, the support assembly 110 is a PMI foam material structure. Since the cover body 100 needs to undergo a high temperature and high pressure process during the molding process, and the support assembly 110 has been filled inside the cover body 100 during the high temperature and high pressure process, the support assembly 110 needs to experience the same high temperature and high pressure environment as the cover body 100. If the support assembly 110 undergoes a large expansion or contraction under the conditions of high temperature and high pressure, it will cause the cover body 100 to deform. Based on this consideration, the embodiment of the present application adopts a support assembly 110 with a PMI foam material structure. Since the PMI foam material has the characteristics of high temperature resistance and high pressure resistance, it can avoid the support assembly 110 from undergoing a large deformation under high temperature and high pressure conditions. Therefore, the support assembly 110 with a PMI foam material structure will not affect the shape of the cover body 100 and the supporting effect on the cover body 100 after the cover body 100 is molded.

[0047] like Figure 2 As shown, in some embodiments, the cover body 100 is not a planar structure, and specifically includes a first top surface portion 101, a second top surface portion 102, a third top surface portion 103, and an edge portion 104. Along the width direction of the cover body 100, the first top surface portion 101, the second top surface portion 102, and the third top surface portion 103 are distributed in sequence. On the front side of the cover body 100, the second top surface portion 102 is higher than the first top surface portion 101 and the third top surface portion 103. On the back side of the cover body 100, the first top surface portion 101 and the third top surface portion 103 both protrude from the second top surface portion 102, that is, the second top surface portion 102 is retracted into the first top surface portion 101 and the third top surface portion 103.

[0048] Moreover, a first step surface 105 is formed between the second top surface portion 102 and the first top surface portion 101, and a second step surface 106 is formed between the second top surface portion 102 and the third top surface portion 103; the edge portion 104 is arranged at the edge of the cover body 100, and is arranged around the first top surface portion 101, the second top surface portion 102, and the third top surface portion 103.

[0049] After the pickup truck hood 10 is installed, the rear end of the pickup truck hood 10 is rotatably connected to the vehicle body, and the front end of the pickup truck hood 10 can rotate around the vehicle body to realize the opening and closing of the pickup truck hood 10.

[0050] Furthermore, both sides of the second top surface portion 102 are arc-shaped, and the width of the second top surface portion 102 gradually increases from the front end to the rear end of the pickup truck hood 10, that is, the length direction of the pickup truck hood; and, the top of the second top surface portion 102 is also arc-shaped, and the height of the second top surface portion 102 gradually decreases from the front end to the rear end of the pickup truck hood 10 until it is at the same height as the first top surface portion 101 and the third top surface portion 103.

[0051] In some embodiments, the outer surfaces of the second top portion 102 and the edge portion 104 have carbon fiber patterns, and the outer surfaces of the first top portion 101 and the third top portion 103 are black, that is, the top highest position and edge position of the outer surface of the cover body 100 have carbon fiber patterns, and the carbon fiber patterns can be diamond patterns, 3K patterns, UD patterns, plain patterns, twill patterns, etc.; and the two sides and two step surfaces of the cover body 100 are painted black to further highlight the carbon fiber patterns.

[0052] In other embodiments, the outer surfaces of the first top surface 101, the second top surface 102, the third top surface 103 and the edge portion 104 have carbon fiber textures, and the first step surface 105 and the second step surface 106 are painted black. Of course, other combinations can also be used.

[0053] like Figure 3 As shown, in some embodiments, the pickup truck tonneau cover 10 further includes a cover 500, which wraps around the outside of the cover 100 and is made of polypropylene. The cover 500 has a thickness of 0.5-2 mm, is elastic, and provides impact resistance and UV protection, further extending the service life of the pickup truck tonneau cover 10.

[0054] like Figure 4 As shown, in some embodiments, the pickup truck box cover 10 also includes a corner code assembly 300, which is arranged at the bottom of the cover body 100 and is used to connect the cover body 100 to the vehicle body; the cover body 100 has a front end, a rear end and two sides, the rear end of the cover body 100 is rotatably connected to the vehicle body, and the front end of the cover body 100 is the opening and closing end of the pickup truck box cover 10.

[0055] Specifically, the corner bracket assembly 300 includes two air springs 310 and two connecting pieces 320, both located on the back of the cover 100. One air spring 310 and one connecting piece 320 are located on each side of the cover 100. The connecting pieces 320 are provided with a first fixing portion 321 and a second fixing portion 322, respectively. The first fixing portion 321 is located on a side of the second fixing portion 322 away from the rear end of the cover 100. One end of the air spring 310 is connected to an area near the front end of the cover 100, while the other end of the air spring 310 is connected to the first fixing portion 321, and the second fixing portion 322 is connected to the vehicle body. When the pickup truck's hood 10 needs to be opened, the two air springs 310 deploy, simultaneously propping up the front end of the cover 100.

[0056] like Figure 5 As shown, the rear end of the cover 100 has at least two C-shaped inserts 130. One end of each C-shaped insert 130 is connected to the cover 100, specifically fixed to the back of the cover 100. The other end of each C-shaped insert 130 is provided with a socket 131. The C-shaped insert 130 is connected to the vehicle body via a ring that passes through the socket 131 on the C-shaped insert 130 and is connected to the vehicle body. The ring is annular and passes through the socket 131 on the C-shaped insert 130 and the corresponding connection hole on the vehicle body to connect the rear end of the pickup truck cover 10, allowing the C-shaped insert 130 and the pickup truck cover 10 to rotate around the vehicle body.

[0057] It should be noted that the C-shaped insert 130 does not mean that the cross section of the insert is only C-shaped, but is just a representation of a similar shape. The insert can also be L-shaped or U-shaped.

[0058] In which, the connecting piece 320 is also provided with a third fixing position 323, which is arranged on the side of the second fixing position 322 away from the first fixing position 321. The third fixing position 323 is sleeved on the C-shaped plug 130, and the third fixing position 323 is a runway-shaped through hole, whose long axis is greater than the width of the C-shaped plug 130, and whose short axis is less than the width of the C-shaped plug 130.

[0059] When the pickup truck hood 10 needs to be opened, the air spring 310 is unfolded. Since the first fixing position 321 and the second fixing position 322 are both vertical runway-shaped and perpendicular to the third fixing position 323, the screw connecting the air spring 310 moves in the first fixing position 321, and the screw connecting the vehicle body moves in the second fixing position 322, thereby enabling the C-shaped insert 130 and the cover body 100 to rotate.

[0060] In addition, the pickup truck compartment cover 10 in the embodiment of the present application is easy to open and close. Figure 6As shown, the pickup truck compartment cover 10 further includes a switch assembly 400, which includes an elastic button unit 410, a first paddle 420, a second paddle 430, a first traction line 440, a second traction line 450, a first elastic locking unit 460, a second elastic locking unit 470, a first fixing plate 480 and a second fixing plate 490, the elastic button unit 410 is connected to the front end of the cover body 100, the first paddle 420, the second paddle 430, the first traction line 440, the second traction line 450, the first elastic locking unit 460, the second elastic locking unit 470, the first fixing plate 480 and the second fixing plate 490. 70. The first fixing plate 480 and the second fixing plate 490 are arranged on the back side of the cover body 100, and the first elastic locking unit 460 and the second elastic locking unit 470 are respectively connected to the cover body 100, and the first fixing plate 480 and the second fixing plate 490 are respectively used to connect to the vehicle body; the first elastic locking unit 460 and the second elastic locking unit 470 are respectively located on both sides of the cover body 100, and the first fixing plate 480 and the second fixing plate 490 are respectively located on both sides of the cover body 100, that is, each side of the cover body 100 has an elastic locking unit and a fixing plate.

[0061] The elastic button unit 410 is disposed through the cover 100, and the control end 411 of the elastic button unit 410 protrudes from the front end of the cover 100. The connection end 412 of the elastic button unit 410 is connected to both the first paddle 420 and the second paddle 430. It should be noted that the first paddle 420 and the second paddle 430 can be two separate structures or an integrated structure.

[0062] As an optional embodiment, the first paddle 420 and the second paddle 430 are two separate structures that do not affect each other and are independently actuated. Furthermore, the first paddle 420 is connected to one end of the first traction wire 440, the other end of which is in transmission connection with the first elastic locking unit 460, which is locked in conjunction with the first fixing piece 480.

[0063] Correspondingly, the second paddle 430 is also connected to one end of the second traction line 450 , and the other end of the second traction line 450 is transmission-connected to the second elastic locking unit 470 , and the second elastic locking unit 470 cooperates with the second fixing plate 490 to lock.

[0064] When the control end 411 of the elastic button unit 410 is pressed, the elastic button unit 410 controls the first traction line 440 and the second traction line 450 to contract through the first paddle 420 and the second paddle 430, respectively, so that the first elastic locking unit 460 is separated from the first fixing plate 480, and the second elastic locking unit 470 is separated from the second fixing plate 490, and the pickup truck lid 10 is opened.

[0065] When the pickup truck lid 10 is closed, the first elastic locking unit 460 is locked with the first fixing plate 480, the second elastic locking unit 470 is locked with the second fixing plate 490, the first traction line 440 and the second traction line 450 are unfolded, and the first paddle 420, the second paddle 430 and the elastic button unit 410 are reset.

[0066] It should be noted that the two paddles, as well as the traction lines, elastic locking units and fixing plates on both sides of the cover body 100 are symmetrically arranged, so that during the opening and closing process of the pickup truck box cover 10, both sides keep moving simultaneously and are evenly stressed, making the opening and closing of the pickup truck box cover 10 stable.

[0067] like Figure 7 As shown, taking the first elastic locking unit 460 as an example, the first elastic locking unit 460 includes a first mounting seat 461, a second mounting seat 462, a first swing arm 463, a second swing arm 464, a first connecting column 465, a second connecting column 466, a first torsion spring 467 and a second torsion spring 468, the first mounting seat 461 is connected to the cover body 100, the second mounting seat 462 and the first mounting seat 461 are arranged in alignment, and a transmission space is formed between the second mounting seat 462 and the first mounting seat 461, the first connecting column 465 and the second connecting column 466 are arranged side by side in the transmission space, the two ends of the first connecting column 465 are respectively connected to the second mounting seat 462 and the first mounting seat 461, and the two ends of the second connecting column 466 are respectively connected to the second mounting seat 462 and the first mounting seat 461.

[0068] The transmission end of the first swing arm 463, the second swing arm 464, the first torsion spring 467 and the second torsion spring 468 are arranged in the transmission space, the main body of the first torsion spring 467 is sleeved on the first connecting column 465, and the torsion arm of the first torsion spring 467 is connected to the first swing arm 463; the main body of the second torsion spring 468 is sleeved on the second connecting column 466, and the torsion arm of the second torsion spring 468 is connected to the second swing arm 464; the first traction line 440 is connected to the connecting end of the first swing arm 463, the transmission end of the first swing arm 463 is transmission-connected to one end of the second swing arm 464, and the other end of the second swing arm 464 is provided with a locking hook 464a; the first fixing plate 480 includes a fixing part 481 and a U-shaped locking rod 482, the fixing part 481 is connected to the vehicle body, and the two ends of the U-shaped locking rod 482 are connected to the fixing part 481.

[0069] When the first traction line 440 contracts, the tightening force of the first traction line 440 is transmitted to the second swing arm 464 through the first swing arm 463, the locking hook 464a of the second swing arm 464 is lifted, and the U-shaped locking rod 482 is disengaged from the locking hook 464a of the second swing arm 464.

[0070] When the first traction line 440 is unfolded, the first swing arm 463 is reset under the action of the first torsion spring 467, the second swing arm 464 is reset under the action of the second torsion spring 468, and the locking hook 464a of the second swing arm 464 sinks.

[0071] like Figure 8 As shown, two protrusions 122 are provided on either side of the bottom of the cover 100. An inner panel 140 is provided inside the protrusion 122. One end of the air spring 310 is connected to the inner panel 140 below the corresponding protrusion 122, and the first mounting seat 461 is connected to the inner panel 140 below the corresponding protrusion 122. This arrangement prevents damage to the cover 100 during drilling and connection of the bottom of the cover 100, avoids cracking of the cover 100 due to a small connection area, and improves the aesthetics of the bottom of the cover 100.

[0072] The inner panel 140 is embedded in the cover 100 through a pre-embedded process during the manufacturing process of the cover 100 , and due to the thickness of the inner panel 140 itself, a local position of the bottom of the cover 100 protrudes outward to form the protrusion 122 .

[0073] like Figure 9As shown, to enhance the structural strength of the cover 100, the pickup truck tonneau cover 10 also includes a reinforcement assembly 200 disposed at the bottom of the cover 100. Furthermore, the reinforcement assembly 200 is integral with the cover 100 and is also constructed of carbon fiber. Alternatively, the reinforcement assembly 200 may be considered a component of the cover 100.

[0074] The reinforcement assembly 200 includes an annular reinforcement rib 210 and at least two strip reinforcement ribs 220. The annular reinforcement rib 210 is annular and is arranged along the edge of the cover body 100; the strip reinforcement rib 220 is arranged within the surrounding range of the annular reinforcement rib 210, and the two ends of the strip reinforcement rib 220 are respectively connected to the opposite sides of the annular reinforcement rib 210; the at least two strip reinforcement ribs 220 are arranged side by side with each other, and the length direction of the strip reinforcement rib 220 is the same as the length direction of the cover body 100.

[0075] As an optional embodiment, since the cover body 100 includes a first top surface portion 101, a second top surface portion 102 and a third top surface portion 103, the reinforcement component 200 in this embodiment only has an annular reinforcement rib 210 and two parallel strip reinforcement ribs 220, and the orthographic projections of the two strip reinforcement ribs 220 are located within the range of the orthographic projection of the second top surface portion 102.

[0076] Since the second top surface portion 102 is the highest and is more susceptible to collisions, and the second top surface portion 102 is also located in the middle of the cover body 100, the gravity impact it bears is more serious. Therefore, the strip reinforcement ribs 220 are provided below the second top surface portion 102 to strengthen the structural strength of the middle area of ​​the cover body 100, while the annular reinforcement ribs 210 strengthen the structural strength of the edge area 116 of the cover body 100. Taken together, the strength of the entire cover body 100 can be effectively strengthened.

[0077] Of course, in other embodiments, the number of the strip reinforcement ribs 220 may not be two, and the selection is made based on actual conditions.

[0078] Further, such as Figure 10 As shown, the reinforcement component 200 also includes a plurality of V-shaped reinforcement ribs 230, and at least two of the V-shaped reinforcement ribs 230 are provided between the adjacent side walls of the strip reinforcement rib 220 and the annular reinforcement rib 210, and the V-shaped bottom of the V-shaped reinforcement rib 230 is connected to the corresponding strip reinforcement rib 220, and the V-shaped top of the V-shaped reinforcement rib 230 is connected to the side wall of the corresponding annular reinforcement rib 210.

[0079] Because the air springs 310 and their connectors, as well as some of the components of the switch assembly 400, are located on both sides of the cover 100, V-shaped reinforcement ribs 230 are provided on both sides of the back of the cover 100 to strengthen the structural strength of both sides of the cover 100. Furthermore, the V-shaped top and bottom ends of the V-shaped reinforcement ribs 230 are connected to the annular reinforcement rib 210 and the strip reinforcement rib 220, respectively. The V-shaped reinforcement ribs 230 combine the annular reinforcement rib 210 and the strip reinforcement rib 220, forming a single unitary component of the reinforcement assembly 200 and effectively reinforcing the strength of all parts of the cover 100. In other embodiments, the V-shaped reinforcement ribs 230 can be replaced with X-shaped or other shaped reinforcement ribs.

[0080] As a specific example, the reinforcement component 200 only has an annular reinforcement rib 210, two parallel strip reinforcement ribs 220 and four V-shaped reinforcement ribs 230, the orthographic projections of the two strip reinforcement ribs 220 are located within the range of the orthographic projection of the second top surface portion 102, and the two strip reinforcement ribs 220 are respectively close to adjacent step surfaces; two of the reinforcement ribs are arranged in parallel between one strip reinforcement rib 220 and the side wall of the adjacent annular reinforcement rib 210, and the other two reinforcement ribs are arranged in parallel between another strip reinforcement rib 220 and the side wall of the adjacent annular reinforcement rib 210.

[0081] Of course, in other embodiments, the number of V-shaped reinforcing ribs 230 on each side of the cover 100 may not be two, and the selection is made based on actual conditions.

[0082] Furthermore, the reinforcement assembly 200 further includes a plurality of edge reinforcement ribs 240, which are disposed between the annular reinforcement rib 210 and the edge of the cover 100. One end of each edge reinforcement rib 240 is connected to the outer side of the annular reinforcement rib 210, and the other end of each edge reinforcement rib 240 is connected to the edge of the cover 100. This design further improves the structural strength of the edge area of ​​the cover 100, preventing the edge of the cover 100 from bending or breaking.

[0083] like Figure 11As shown, as an optional embodiment, the reinforcement assembly 200 further includes at least two transverse reinforcement ribs 250, which are arranged in parallel; the transverse reinforcement ribs 250 are arranged between the two strip reinforcement ribs 220, and the two ends of the transverse reinforcement ribs 250 are respectively connected to the two strip reinforcement ribs 220. Since the cover 100 has a large area and a small thickness, when transporting and installing the cover 100, if only a force is applied to a part of the cover 100, it is easy to cause the cover 100 to twist and deform, and in severe cases, it may cause the cover 100 to crack. Based on this, the embodiment of the present application adds transverse reinforcement ribs 250 to the middle area of ​​the cover 100 to further improve the structural strength of the middle area of ​​the cover 100, improve the torsion resistance of the pickup truck box cover 10, and ensure the stability of the pickup truck box cover 10.

[0084] As a specific example, the reinforcement component 200 has three transverse reinforcement ribs 250, which are arranged at equal intervals in sequence. The transverse reinforcement ribs 250 are strip-shaped structures, and the three transverse reinforcement ribs 250 are respectively arranged perpendicular to the strip reinforcement ribs 220 on both sides.

[0085] Of course, in other embodiments, the reinforcement component 200 may have only two or more than four transverse reinforcement ribs 250, and the transverse reinforcement ribs 250 may be arranged obliquely with respect to the strip reinforcement ribs 220, or even the transverse reinforcement ribs 250 may be designed in other shapes.

[0086] like Figure 12 As shown, the embodiment of the present application also discloses a method for manufacturing a pickup truck box cover, which is used to manufacture the pickup truck box cover as described above. The manufacturing method includes the following steps:

[0087] S1: pasting a first preset number of layers of carbon fiber membrane on the mold;

[0088] S2: placing a support assembly at a preset position of the carbon fiber membrane;

[0089] S3: pasting a second preset number of layers of carbon fiber membrane on the support assembly;

[0090] S4: Separating all the carbon fiber membranes and the supporting assembly from the mold to obtain a pickup truck tonneau cover.

[0091] Specifically, in step S1, a carbon fiber film is directly attached to the mold for the pickup truck bed lid, such that the attached carbon fiber film forms the bottom shape of the lid body and sinks into the groove area of ​​the mold to form a reinforcement component for the bottom of the pickup truck bed lid. The first preset number of layers is 3-6. It should be noted that each layer of carbon fiber film can be composed of multiple independent carbon fiber film blocks, with different carbon fiber film blocks attached to different areas of the mold to prevent large wrinkles from forming between the attached carbon fiber films.

[0092] In step S2, the preset position is specifically where the reinforcement assembly is located, i.e., where the carbon fiber membrane is sunken. The support assembly can be made of multiple strips of PMI foam material. By placing the PMI foam material structure in the corresponding sunken positions on the carbon fiber membrane, the overall structural strength of the pickup truck cover is strengthened and the reinforcement assembly and the carbon fiber membrane on the top of the cover are prevented from sinking. At the same time, an inner panel can be placed on the carbon fiber membrane for pre-embedded processing.

[0093] In step S3, the second preset number of layers is 3-6, with the upper carbon fiber membrane covering the lower carbon fiber membrane and the support assembly. Furthermore, the carbon fiber membrane in step S3 can also be composed of multiple independent carbon fiber membrane blocks, with different carbon fiber membrane blocks being attached to different areas of the mold.

[0094] In steps S1 and S3, in order to improve the structural strength of the pickup truck tonneau cover, glass fiber or other tough materials can be added between the carbon fiber membranes.

[0095] In step S4, the mold is placed in a high-temperature environment for treatment so that all the carbon fiber membranes are fused into an integrated structure. After cooling, a cover body with internal support components is obtained, which is also the pickup truck box cover.

[0096] In addition, if Figure 13 As shown, the manufacturing method further includes a repairing step, which is located after step S4 and specifically includes:

[0097] S5: sandblasting the outer surface of the cover;

[0098] S6: Finding defects on the outer surface of the cover;

[0099] S7: applying epoxy resin glue to the defect;

[0100] S8: polishing the epoxy resin glue at the defect;

[0101] S9: polishing the outer surface of the cover;

[0102] S10: spraying colored paint on the defects, and then applying transparent paint on the outer surface of the cover;

[0103] S11: polishing the outer surface of the cover.

[0104] Through the above-mentioned repair design, the outer surface of the pickup truck's hood is free of defects and has a good glossiness, and the overall aesthetics is further improved.

[0105] It should be noted that the limitations on the various steps involved in this solution do not limit the order of the steps without affecting the implementation of the specific solution. The steps written in front can be executed first, later, or even simultaneously. The solutions of different embodiments can be combined and applied without conflict. As long as this solution can be implemented, it should be regarded as falling within the scope of protection of this application.

[0106] The above content is a further detailed description of the present application in conjunction with specific optional implementation methods, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, they can make several simple deductions or substitutions without departing from the concept of the present application, which should be considered to fall within the scope of protection of the present application.
