Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and more particularly to a pickup truck bed cover. Background Technology

[0002] A pickup truck is a vehicle type that uses a car-like front end and cab, while also having an open cargo bed. It offers the comfort of a car while maintaining powerful performance, and its cargo-carrying capacity and off-road capability are even greater than that of a car, making it an important part of the automotive market. The most common pickup truck type is the double-cab pickup. Pickups can be used as special-purpose vehicles, multi-purpose vehicles, official vehicles, commercial vehicles, or family vehicles for cargo transport, tourism, and rental purposes.

[0003] Pickup trucks, vehicles with a rear cargo bed, are typically used to load goods, and the cargo bed is usually fitted with a cover to protect the goods from external environmental factors. However, current pickup truck cargo covers are quite heavy, making them inconvenient to move and install. Utility Model Content

[0004] The purpose of this application is to provide a pickup truck bed cover with a lighter weight to facilitate the handling and installation of the pickup truck bed cover.

[0035] It should be understood that the terminology, specific structural and functional details used herein are merely for describing particular embodiments and are representative. However, this application may be implemented in many alternative forms and should not be construed as being limited to the embodiments set forth herein.

[0036] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or implying the number of technical features indicated. Therefore, unless otherwise stated, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; "multiple" means two or more. The term "comprising" and any variations thereof mean non-exclusive inclusion, where one or more other features, integers, steps, operations, units, components, and / or combinations thereof may be present or added.

[0037] In addition, terms such as “center,” “horizontal,” “up,” “down,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer” that indicate orientation or positional relationship are based on the orientation or relative positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this application and do not indicate that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Currently, most pickup truck bed covers are constructed from cold-rolled steel sheets, fiberglass, and aluminum alloys to ensure strength. However, these metal panels are heavy, making them inconvenient to transport and install, especially one-piece, non-removable panel structures. Furthermore, the aesthetics of the bed cover surface need improvement. Even with painting or applying a protective film, the surface coating is generally exposed to the external environment, and over time, this damages the cover's appearance.

[0040] Based on this, this application provides a pickup truck bed cover 10, such as... Figure 1 and Figure 2 As shown, the pickup truck bed cover 10 includes a panel 100 and a corner bracket assembly 300. The panel 100 includes a bottom cover 120 and a top cover 110. The top cover 110 is fully fitted to the bottom cover 120. The bottom cover 120 is made of rigid plastic, and the main body of the top cover 110 is made of carbon fiber material. It can be understood that most or even all of the top cover 110 is made of carbon fiber material. The corner bracket assembly 300 is disposed on the side of the bottom cover 120 opposite to the top cover 110 and is used to connect the panel 100 to the vehicle body.

[0041] This embodiment of the application sets the pickup truck bed cover 10's panel 100 into a double-layer structure consisting of a bottom cover 120 and a top cover 110. The inner bottom cover 120 is made of rigid plastic to ensure the shape and strength of the panel 100, while the outer top cover 110 is mainly made of carbon fiber. Because carbon fiber is lightweight, the overall weight of the panel 100 is reduced, facilitating installation and transportation. Furthermore, the carbon fiber structure exhibits more stable surface patterns and colors, a longer service life, and resistance to high and low temperatures, thus ensuring the aesthetic appearance of the bed cover surface for an extended period.

[0042] In this embodiment, the cover 110 includes multiple carbon fiber cloth layers 111, which are stacked together. Compared to directly injection molding the cover 110 from carbon fiber material, the cover 110 formed by laminating multiple layers of carbon fiber cloth is simpler to manufacture, faster to produce, and lower in cost. Each carbon fiber cloth layer 111 can be an adhesive-coated carbon fiber cloth, in which case the carbon fiber cloths can be directly laminated together; alternatively, the carbon fiber cloth layers 111 can be non-adhesive carbon fiber cloth, in which case an additional layer of impregnating adhesive needs to be applied to bond the upper and lower layers of carbon fiber cloth.

[0043] Specifically, the cover 110 includes 5-8 carbon fiber cloth layers 111, that is, the cover 110 is composed of 5-8 layers of carbon fiber cloth stacked together. Through experiments, it has been found that this arrangement can ensure the hardness of the cover 110 itself, facilitate its alignment with the bottom cover 120, and also cover up the defects at the junction of the carbon fiber cloth.

[0044] In another embodiment, the face cover 110 includes 5-8 carbon fiber cloth layers 111 and 1-3 fiberglass layers 112. Each fiberglass layer 112 is disposed between adjacent carbon fiber cloth layers 111, i.e., one fiberglass layer 112 is disposed between two carbon fiber cloth layers 111. By disposing of fiberglass layers 112 between the carbon fiber cloth layers 111, the structural strength of the face cover 110 is further improved, as is its heat resistance. Each fiberglass layer 112 is composed of multiple fiberglass strips, which can be distributed on the top, edge, or other local areas of the face cover 110, or distributed throughout the entire face cover 110 area.

[0045] As a specific example, such as Figure 3 As shown, the cover 110 is composed of three carbon fiber cloth layers 111 and one glass fiber layer 112, with the glass fiber layer 112 disposed between the third and fourth carbon fiber cloth layers 111. In other examples, the number and position of the carbon fiber cloth layers 111 and the glass fiber layers 112 can also be combined in other ways, which will not be listed here.

[0046] like Figure 4 As shown, the cover 110 is not a planar structure, but specifically includes a first top surface area 113, a second top surface area 114, a third top surface area 115, and an edge area 116. The first top surface area 113, the second top surface area 114, and the third top surface area 115 are disposed on the front side of the cover 110. The second top surface area 114 is located between the first top surface area 113 and the third top surface area 115, and the second top surface area 114 is higher than the first top surface area 113 and the third top surface area 115. The first top surface area 113 and the third top surface area 115 are at the same height. A first stepped surface 117 is formed between the second top surface area 114 and the first top surface area 113, and a second stepped surface 118 is formed between the second top surface area 114 and the third top surface area 115. The edge area 116 is disposed on the edge of the cover 110 and surrounds the first top surface area 113, the second top surface area 114, and the third top surface area 115.

[0047] After the pickup truck bed cover 10 is installed, the rear end of the pickup truck bed cover 10 is rotatably connected to the vehicle body, and the front end of the vehicle body can rotate around the vehicle body to realize the opening and closing of the pickup truck bed cover 10.

[0048] In this embodiment, the first top surface area 113, the second top surface area 114, and the third top surface area 115 are distributed sequentially along the distance direction on both sides of the pickup truck bed cover 10. The two sides of the second top surface area 114 are arc-shaped, and the width of the second top surface area 114 gradually increases from the front end to the rear end of the pickup truck bed cover 10; moreover, the top of the second top surface area 114 is also arc-shaped, and the height of the second top surface area 114 gradually decreases from the front end to the rear end of the pickup truck bed cover 10 until it is at the same height as the first top surface area 113 and the third top surface area 115.

[0049] In this embodiment, the outermost carbon fiber fabric layer 111 is composed of multiple carbon fiber fabric pieces spliced ​​together. Since the cover 110 is not a flat surface, having both downward-extending edges and an uneven top, using a single piece of carbon fiber fabric to form the carbon fiber fabric layer 111 would result in wrinkles and unevenness at corners and junctions, affecting the aesthetics of the cover 110's surface. Alternatively, all carbon fiber fabric layers 111 can be composed of multiple carbon fiber fabric pieces spliced ​​together to avoid wrinkles and unevenness, thus further improving the flatness of the cover 110's surface. Of course, depending on actual needs, the lower carbon fiber fabric layer 111 can also be a single piece of carbon fiber fabric, with only the upper carbon fiber fabric layer 111 composed of multiple carbon fiber fabric pieces spliced ​​together.

[0050] Specifically, such as Figure 5 As shown, the outermost carbon fiber fabric layer 111 includes a first carbon fiber fabric block 111a, a second carbon fiber fabric block 111b, and a third carbon fiber fabric block 111c. The first carbon fiber fabric block 111a is at least disposed in the first top surface area 113, the second carbon fiber fabric block 111b is at least disposed in the second top surface area 114, and the third carbon fiber fabric block 111c is at least disposed in the third top surface area 115. The joint between the first carbon fiber fabric block 111a and the second carbon fiber fabric block 111b is located on the first step surface 117, and the joint between the third carbon fiber fabric block 111c and the second carbon fiber fabric block 111b is located on the second step surface 118. The first step surface 117 and the second step surface 118 are treated with a concealing effect, that is, the joint between the first carbon fiber fabric block 111a and the second carbon fiber fabric block 111b is concealed, and the joint between the third carbon fiber fabric block 111c and the second carbon fiber fabric block 111b is concealed.

[0051] Since the first top surface area 113, the second top surface area 114, and the third top surface area 115 are located on top of the cover 110, after the pickup truck bed cover 10 is installed, users will only notice the top of the cover 110. Using a single piece of carbon fiber fabric for the first top surface area 113, the second top surface area 114, and the third top surface area, without any seams, results in a more aesthetically pleasing appearance. Furthermore, because the first stepped surface 117 and the second stepped surface 118 have small areas and are sloping interfaces, placing the seams of the carbon fiber fabric in this position makes them difficult to observe and less likely to affect the overall aesthetics of the cover 110. In particular, this application also provides concealing treatment for the first stepped surface 117 and the second stepped surface 118, further preventing them from being observed by the user, making the entire surface of the cover 110 appear as a single unit.

[0052] The concealing process can be achieved by applying a black coating, i.e., applying black paint or a black layer to the seam; or by applying a patterned texture to the seam, i.e., drawing a pattern on the seam. Of course, other concealing methods can also be used, which will not be listed here.

[0053] It should be noted that the seam is not where the edges of the two carbon fiber fabric pieces touch, but rather where the edges of the two carbon fiber fabric pieces overlap to prevent different carbon fiber fabric pieces from falling off within the same layer. However, this will result in a slight height difference between the edges of the carbon fiber fabric pieces within the same layer. This issue can be perfectly concealed through the concealing design.

[0054] In addition, the outermost carbon fiber fabric layer 111 also includes a fourth carbon fiber fabric block 111d, which is at least disposed in the edge area 116. The seam between the fourth carbon fiber fabric block 111d and the first carbon fiber fabric block 111a is disposed at the corner position between the edge area 116 and the first top surface area 113. The seam between the fourth carbon fiber fabric block 111d and the second carbon fiber fabric block 111b is disposed at the corner position between the edge area 116 and the second top surface area 114. The seam between the fourth carbon fiber fabric block 111d and the third carbon fiber fabric block 111c is disposed at the corner position between the edge area 116 and the third top surface area 115.

[0055] Since the top and edge of the cover 110 are not on the same plane, using different carbon fiber fabrics for the edge area 116 and the top area can avoid wrinkles at the corners. Furthermore, in this embodiment, the seam between the carbon fiber fabric of the edge area 116 and the carbon fiber fabric of the top area is located at the corner (rounded corner junction) between the edge area 116 and the top area. Because the corner area is small and generally not easily noticed by users, the seam at the corner is not easily observed and will not affect the overall aesthetics of the pickup truck bed cover 10.

[0056] Furthermore, the fourth carbon fiber cloth block 111d can be further divided into four carbon fiber cloth blocks. Each of the four side edges of the cover 110 is provided with a separate carbon fiber cloth block, and the seam of the adjacent carbon fiber cloth blocks is set at the corner between the two sides. This can prevent wrinkles from appearing at the side corners and also prevent the seam from being observed.

[0057] In this embodiment, after the cover 110 is laid with carbon fiber cloth, it needs to undergo sanding, repair, polishing, and painting to make the surface of the cover 110 have a higher gloss and better aesthetics. Moreover, in a darker environment, the first step surface 117, the second step surface 118, and the corner positions will appear black, making it difficult to observe the seams; in a brighter environment, the first step surface 117, the second step surface 118, and the corner positions will reflect light, making it difficult to observe the seams.

[0058] As a specific example, the surfaces of the second carbon fiber fabric block 111b and the fourth carbon fiber fabric block 111d have carbon fiber textures, while the surfaces of the first carbon fiber fabric block 111a and the third carbon fiber fabric block 111c are black. Specifically, the top highest point and edge of the cover 110 have carbon fiber textures, which can be diamond patterns, 3K patterns, UD patterns, plain weave, twill weave, etc. The top two sides and two stepped surfaces of the cover 110 are painted black to further highlight the carbon fiber pattern. As another specific example, the surfaces of the first carbon fiber fabric block 111a, the second carbon fiber fabric block 111b, the third carbon fiber fabric block 111c, and the fourth carbon fiber fabric block 111d have carbon fiber textures, while the first stepped surface 117 and the second stepped surface 118 are painted black. Of course, other combinations can also be used.

[0059] like Figure 6 The pickup truck bed cover 10 also includes a cover 500, which covers the outer side of the cover 110. The cover 500 is made of polypropylene material. The cover 500 is 0.5-2mm thick, elastic, and can provide impact resistance and UV protection, further extending the service life of the pickup truck bed cover 10.

[0060] like Figure 7 As shown in the embodiment, this application also discloses a method for manufacturing a pickup truck bed cover, used to manufacture the pickup truck bed cover 10 as described above, including the following steps:

[0061] S1: A bottom cover is made of rigid plastic;

[0062] S2: A faceplate is formed on a mold, and the main body of the faceplate is made of carbon fiber material;

[0063] S3: Connect the bottom cover and the top cover together.

[0064] Specifically, in step S1, the bottom cover 120 can be manufactured using injection molding. For example... Figure 8 As shown, in one specific manner, in step S2, the shape of the mold corresponds to that of the faceplate 110, and carbon fiber cloth is directly bonded to the mold, specifically including:

[0065] S21: Lay a layer of carbon fiber cloth on the first top surface area, the second top surface area, the third top surface area and the edge area of ​​the mold corresponding to the cover;

[0066] S22: After repeating the above steps 2-4 times, lay a layer of glass fiber on the surface of the carbon fiber cloth;

[0067] S23: Continue to lay a layer of carbon fiber cloth on the first top surface area, the second top surface area, the third top surface area and the edge area of ​​the mold cover, repeating 3-4 times.

[0068] That is, step S22 involves laying 2-4 layers of carbon fiber cloth 111, followed by laying a layer of fiberglass 112; step S23 involves laying 3-4 layers of carbon fiber cloth 111 on top of the fiberglass 112. Of course, in step S23, the step of laying the fiberglass 112 can also be inserted while laying the carbon fiber cloth 111.

[0069] In addition, the surface of the cover 110 is treated with sandblasting, polishing, and coating with transparent varnish, such as... Figure 9 As shown, the manufacturing method further includes a repair step, which includes:

[0070] S41: Sandblast the surface of the cover;

[0071] S42: Locate defects on the surface of the faceplate;

[0072] S43: Apply epoxy resin adhesive to the defect;

[0073] S44: Polish the epoxy resin adhesive at the defective area;

[0074] S45: Polish the surface of the cover;

[0075] S46: Spray colored paint onto the defect, and then coat the surface of the cover with transparent paint;

[0076] S47: Polish the surface of the cover.

[0077] The repair step can be located between steps S2 and S3, after the top cover 110 is made, and the repair step can be located after step S3, after the bottom cover 120 and the top cover 110 are connected, and then the repair step can be performed on the top cover 110.

[0078] In this embodiment, the top cover 110 and the bottom cover 120 are bonded together, that is, the bottom surface of the top cover 110 and the top surface of the bottom cover 120 are directly bonded together with an adhesive material, specifically epoxy resin adhesive. The high strength, high toughness, high heat resistance and cold resistance of epoxy resin adhesive are used to prevent the edge warping and detachment of the top cover 110 and the bottom cover 120 after bonding.

[0079] After the top cover 110 and the bottom cover 120 are joined and bonded together, the edges of the top cover 110 and the bottom cover 120 are flush, and the bottom cover 120 supports the top cover 110 at all points, ensuring the structural strength of the plate 100 at all points; moreover, the plate 100 has better overall integrity, just like a one-piece structure.

[0080] Specifically, the bottom cover 120 is made of ABS material. ABS material has high strength, good toughness and light weight. When combined with the top cover 110, which is mainly made of carbon fiber material, it plays a good complementary role and further highlights the light weight of the plate 100.

[0081] Because ABS material expands and contracts with temperature changes, while carbon fiber material is unaffected by temperature, the bottom cover 120 may shrink in cold weather after it is bonded to the top cover 110, especially in corner areas, potentially causing the bottom cover 120 and top cover 110 to detach. Therefore, this embodiment employs a shrinkage process during the manufacturing of the bottom cover 120 to prevent shrinkage after the bottom cover 120 and top cover 110 are bonded.

[0082] Or, such as Figure 10 As shown, a cut 121 is provided at the corner of the bottom cover 120 so that after the bottom cover 120 shrinks, the part of the bottom cover 120 at the cut 121 provides shrinkage allowance and expansion heat. When the bottom cover 120 shrinks and expands, it avoids pulling or squeezing the top cover 110, which would cause the adhesive material between the bottom cover 120 and the top cover 110 to loosen.

[0083] like Figure 11 As shown, the plate 100 has a front end, a rear end, and two sides. The rear end of the plate 100 is rotatably connected to the vehicle body, and the front end of the plate 100 is the opening and closing end of the plate 100.

[0084] The corner bracket assembly 300 includes two air springs 310 and two connecting pieces 320, all located on the back of the bottom cover 120. Each side of the plate 100 has one air spring 310 and one connecting piece 320, with the connecting piece 320 also located at the rear end of the plate 100. The connecting piece 320 has a first fixing position 321 and a second fixing position 322 arranged side-by-side. The first fixing position 321 is located on the side of the second fixing position 322 away from the rear end of the plate 100. One end of each air spring 310 is connected to a region near the front end of the plate 100, and the other end is connected to the first fixing position 321. The second fixing position 322 is connected to the vehicle body. When the pickup truck bed cover 10 needs to be opened, the two air springs 310 unfold, simultaneously supporting the front end of the plate 100.

[0085] like Figure 12As shown, the rear end of the plate 100 has at least two C-shaped inserts 130. One end of each C-shaped insert 130 is connected to the plate 100, specifically fixed to the back of the bottom cover 120. The other end of each C-shaped insert 130 has an insertion hole 131. The C-shaped insert 130 is connected to the vehicle body by passing through the insertion hole 131 via a collar. The collar is annular and passes through the insertion hole 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 bed cover 10, allowing the C-shaped insert 130 and the pickup truck bed cover 10 to rotate around the vehicle body.

[0086] It should be noted that the C-shaped insert 130 is not interpreted as the cross-section of the insert being only C-shaped, but rather as a similar shape representation. The insert can also be L-shaped or U-shaped.

[0087] The connecting piece 320 is further provided with a third fixing position 323. The third fixing position 323 is located 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 insert 130, and the third fixing position 323 is a racetrack-shaped through hole with its major axis greater than the width of the C-shaped insert 130 and its minor axis less than the width of the C-shaped insert 130.

[0088] When the pickup truck bed cover 10 needs to be opened, the air spring 310 unfolds. Since the first fixing position 321 and the second fixing position 322 are both vertical racetrack-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 to rotate with the plate 100.

[0089] Furthermore, the pickup truck bed cover 10 in this embodiment is simple to open and close, such as... Figure 13As shown, the pickup truck bed cover 10 also includes a switch assembly 400, which includes a resilient button unit 410, a first lever 420, a second lever 430, a first traction cable 440, a second traction cable 450, a first resilient locking unit 460, a second resilient locking unit 470, a first fixing piece 480, and a second fixing piece 490. The resilient button unit 410 is connected to the front end of the plate body 100. The first lever 420, the second lever 430, the first traction cable 440, the second traction cable 450, the first resilient locking unit 460, and the second resilient locking unit 470... The first fixing piece 480 and the second fixing piece 490 are disposed on the side of the bottom cover 120 away from the top cover 110, and the first elastic locking unit 460 and the second elastic locking unit 470 are respectively connected to the bottom cover 120, and the first fixing piece 480 and the second fixing piece 490 are respectively connected 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 plate 100, and the first fixing piece 480 and the second fixing piece 490 are respectively located on both sides of the plate 100, that is, each side of the plate 100 has an elastic locking unit and a fixing piece.

[0090] The elastic button unit 410 is inserted through the plate 100, and the control end 411 of the elastic button unit 410 protrudes from the front end of the plate 100. The connection end 412 of the elastic button unit 410 is connected to both the first paddle 420 and the second paddle 430. The first paddle 420 and the paddle can be two separate structures or an integral structure.

[0091] Preferably, the first lever 420 and the lever are two separate structures that do not affect each other and operate independently. Furthermore, the first lever 420 is connected to one end of the first traction line 440, and the other end of the first traction line 440 is connected to the first elastic locking unit 460, which engages with the first fixing piece 480 for locking. Correspondingly, the second lever 430 is connected to one end of the second traction line 450, and the other end of the second traction line 450 is connected to the second elastic locking unit 470, which engages with the second fixing piece 490 for locking.

[0092] When the control terminal 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 retract via the first paddle 420 and the second paddle 430, respectively, so that the first elastic locking unit 460 separates from the first fixing piece 480, the second elastic locking unit 470 separates from the second fixing piece 490, and the pickup truck bed cover 10 opens.

[0093] When the pickup truck bed cover 10 is closed, the first elastic locking unit 460 locks with the first fixing piece 480, the second elastic locking unit 470 locks with the second fixing piece 490, the first traction line 440 and the second traction line 450 unfold, and the first paddle 420, the second paddle 430 and the elastic button unit 410 reset.

[0094] 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 plate 100 are symmetrically arranged, so that the two sides of the pickup truck bed cover 10 move simultaneously and are evenly stressed during the opening and closing process, making the pickup truck bed cover 10 stable in opening and closing.

[0095] like Figure 14 As shown, taking the first elastic locking unit 460 as an example, the first elastic locking unit 460 includes a first mounting base 461, a second mounting base 462, a first swing arm 463, a second swing arm 464, a first connecting post 465, a second connecting post 466, a first torsion spring 467, and a second torsion spring 468. The first mounting base 461 is connected to the bottom cover 120. The second mounting base 462 and the first mounting base 461 are arranged opposite each other, and a transmission space is formed between the second mounting base 462 and the first mounting base 461. The first connecting post 465 and the second connecting post 466 are arranged side by side in the transmission space. The two ends of the first connecting post 465 are respectively connected to the second mounting base 462 and the first mounting base 461, and the two ends of the second connecting post 466 are respectively connected to the second mounting base 462 and the first mounting base 461.

[0096] 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 disposed within the transmission space. The main body of the first torsion spring 467 is sleeved on the first connecting post 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 post 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 connected to one end of the second swing arm 464. 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 both ends of the U-shaped locking rod 482 are connected to the fixing part 481.

[0097] When the first traction line 440 retracts, 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 disengages from the locking hook 464a of the second swing arm 464.

[0098] When the first traction line 440 is deployed, 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.

[0099] like Figure 15 As shown, the bottom cover 120 has two protrusions 122 on each side, and a gap space is provided between the protrusions 122 and the top cover 110. An inner plate 140 is provided in the gap space. One end of the air spring 310 is connected to the inner plate 140 below the corresponding protrusion 122, and the first mounting base 461 is connected to the inner plate 140 below the corresponding protrusion 122. This design avoids damage to the top cover 110 when drilling and connecting the bottom plate, avoids cracking of the bottom cover 120 due to a small connection area, and also improves the aesthetics of the bottom of the bottom cover 120.

[0100] like Figure 16 As shown, in order to improve the strength of the bottom cover 120 and the plate 100, the pickup truck bed cover 10 also includes a reinforcing component 200. The reinforcing component 200 is disposed on the side of the bottom cover 120 away from the front cover 110. The reinforcing component 200 can be an integral structure with the bottom cover 120 and is a structure retained when the bottom cover 120 is formed.

[0101] The reinforcing component 200 includes an annular reinforcing rib 210 and at least two strip reinforcing ribs 220. The annular reinforcing rib 210 is annular and is disposed along the edge of the bottom cover 120. The strip reinforcing ribs 220 are disposed within the surrounding area of ​​the annular reinforcing rib 210, and the two ends of the strip reinforcing ribs 220 are respectively connected to the opposite sides of the annular reinforcing rib 210. The at least two strip reinforcing ribs 220 are arranged side by side, and the length direction of the strip reinforcing ribs 220 is the same as the length direction of the bottom cover 120.

[0102] As a specific example, the front of the cover 110 has a first top surface area 113, a second top surface area 114, and a third top surface area 115. The second top surface area 114 is located between the first top surface area 113 and the third top surface area 115, and the second top surface area 114 is higher than the first top surface area 113 and the third top surface area 115. In this example, the reinforcing component 200 only has an annular reinforcing rib 210 and two parallel strip reinforcing ribs 220. The orthographic projection of the two strip reinforcing ribs 220 is located within the orthographic projection range of the second top surface area 114, and the two strip reinforcing ribs 220 are respectively close to the adjacent step surface.

[0103] Since the second top surface area 114 of the cover 110 is the highest, it is easily affected by collisions. Moreover, since the second top surface area 114 is not yet in the middle of the cover 110, the impact of gravity on it is more severe. Therefore, a strip reinforcing rib 220 is provided below the second top surface area 114 to strengthen the structural strength of the middle area of ​​the cover 110 and the bottom cover 120, while the annular reinforcing rib 210 strengthens the structural strength of the edge area 116 of the cover 110 and the bottom cover 120. In combination, the strength of the entire cover 110 and the bottom cover 120 can be effectively strengthened.

[0104] Of course, in other embodiments, the number of strip reinforcing ribs 220 may not be two, and the specific choice can be made according to the actual situation.

[0105] Furthermore, such as Figure 17 As shown, the reinforcing component 200 also includes a plurality of V-shaped reinforcing ribs 230. At least two V-shaped reinforcing ribs 230 are provided between adjacent sidewalls of the strip reinforcing rib 220 and the annular reinforcing rib 210. The bottom of the V-shaped reinforcing rib 230 is connected to the corresponding strip reinforcing rib 220, and the top of the V-shaped reinforcing rib 230 is connected to the sidewall of the corresponding annular reinforcing rib 210.

[0106] Since the bottom cover 120 is provided with air springs 310 and their connecting parts on both sides, and also with part of the structure of the switch assembly 400, the structural strength of the bottom cover 120 is strengthened by providing V-shaped reinforcing ribs 230 on both sides of the back of the bottom cover 120; moreover, the top and bottom ends of the V-shaped reinforcing ribs 230 are connected to the annular reinforcing ribs 210 and the strip reinforcing ribs 220 respectively, and the annular reinforcing ribs 210 and the strip reinforcing ribs 220 are combined by the V-shaped reinforcing ribs 230, so that the reinforcing assembly 200 forms a whole, which can effectively strengthen the strength of the face cover 110 and the bottom cover 120.

[0107] As a specific example, the reinforcing component 200 has only annular reinforcing rib 210, two parallel strip reinforcing ribs 220 and four V-shaped reinforcing ribs 230. The orthographic projection of the two strip reinforcing ribs 220 is located within the orthographic projection range of the second top surface area 114, and the two strip reinforcing ribs 220 are respectively close to the adjacent step surface. The two reinforcing ribs are arranged side by side between the side wall of one strip reinforcing rib 220 and the adjacent annular reinforcing rib 210, and the other two reinforcing ribs are arranged side by side between the side wall of another strip reinforcing rib 220 and the adjacent annular reinforcing rib 210.

[0108] Of course, in other embodiments, the number of V-shaped reinforcing ribs 230 on each side of the bottom cover 120 may not be two, depending on the actual situation.

[0109] Furthermore, such as Figure 17 As shown, the reinforcing component 200 also includes a plurality of edge reinforcing ribs 240. The edge reinforcing ribs 240 are disposed between the annular reinforcing rib 210 and the edge of the bottom cover 120. One end of each edge reinforcing rib 240 is connected to the outer side of the annular reinforcing rib 210, and the other end is connected to the side of the bottom cover 120. This design further improves the structural strength of the bottom cover 120 and the edge area 116 of the frame, preventing bending and breakage at the edges of the bottom cover 120 and the frame.
