Description

Technical Field

[0001] This utility model relates to the field of pickup truck technology, specifically to a folding soft top side rail profile for pickup trucks. Background Technology

[0002] Pickup trucks, as a type of vehicle that combines cargo and passenger transport functions, have open cargo beds that, while providing powerful loading capacity, also expose goods directly to wind, sun, and rain. This can cause damage to the goods and create safety hazards. To address this issue, a cargo cover has become a crucial component.

[0003] Early models commonly used non-removable hard-sided canopies. While providing reliable protection, their inherent drawbacks were significant: they increased overall vehicle weight and energy consumption, had higher manufacturing costs, and, most importantly, severely limited the loading flexibility and practicality of the cargo box when loading large or oversized items. To address the shortcomings of hard-sided canopies, soft-sided canopies were developed. In the overall structure of a soft-sided canopy, the side rail profiles are a key component forming its supporting frame. This frame typically consists of a front rail, a rear rail, and two side rails, which are fixed to the side beams on both sides of the cargo box by the side rail profiles, providing the main support for the entire soft-sided canopy.

[0004] However, the current side rail profiles, as fixing components for the edges of tarpaulins, still face some technical challenges, as follows:

[0005] The current side rail profiles are made of coated aluminum alloy, which is highly corrosion-resistant and can withstand harsh weather (such as salt spray and sun exposure). However, the fixed soft canopy cannot be folded well, meaning that the side rail profiles are not fixed to the edge of the canopy. If forced folding is required, the screws fixing the edge of the canopy must be removed, or the connection method must be changed, i.e., guide rails and sliders must be installed. However, this operation will increase costs.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] The purpose of this utility model is to provide a side rail profile for a pickup truck folding soft top cover.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A folding soft top side rail profile for pickup trucks includes a profile body. Viewed in cross-section, the profile body includes a first plate, a second plate, and a third plate. The end of the first plate is integrally connected to the end of the second plate, and the extension line of the first plate along its length intersects the extension line of the second plate along its length at an acute angle. The end of the third plate is integrally connected to the end of the second plate furthest from the first plate, and the other end of the third plate is integrally connected to the surface of the first plate, forming a connection point on the surface of the first plate. The second plate, the third plate, and the end of the first plate located between the connection point and the connection point between the first and second plates are also included. The areas between the two plates form a closed triangular structure; a fourth plate is provided at the connection end between the second plate and the third plate, and a bent portion is provided at the end of the fourth plate away from the triangular structure. The bent portion is formed by bending the end of the fourth plate away from the triangular structure toward the first plate at a set angle. A locking protrusion is provided on the surface of the first plate, directly opposite the location of the bent portion; the areas of the fourth plate, the third plate, and the first plate between the connection point and the locking protrusion form a receiving groove structure; the bent portion and the locking protrusion are located at the opening of the receiving groove structure, and the two cooperate with each other so that the size of the opening of the receiving groove structure is smaller than the internal size of the receiving groove structure.

[0010] In the above solution, the edge of the tarpaulin can be accommodated and slidably connected by a receiving groove structure composed of the fourth plate, the third plate and the first plate working together. The bending part and the locking protrusion form a limiting structure at the groove opening, so that the tarpaulin can slide and fold along the bottom of the receiving groove when under force, without the need to remove screws or add guide rail sliders. This ensures the connection is stable and achieves the function of quick unfolding and folding, effectively reducing the cost of use and improving the ease of operation.

[0011] Unlike existing technologies, this utility model utilizes an integrated profile structure design, eliminating the need for additional installation components, significantly reducing material and assembly costs while improving structural strength and sealing performance. The presence of the receiving groove structure ensures that the edge of the tarpaulin is stably limited after installation, preventing loosening or abnormal noise caused by vehicle vibration. Furthermore, the design of the receiving groove structure's internal dimensions being larger than the groove opening ensures that the bent portion and the locking protrusion can effectively form a one-way locking structure, facilitating the rapid installation and positioning of the tarpaulin assembly.

[0012] The preferred angle is 90 degrees.

[0013] In a further technical solution, both the bending portion and the locking protrusion are provided with a thickened area of ​​equal thickness, the thickness of which is greater than the thickness of the first plate and / or the fourth plate.

[0014] The receiving groove structure acts as a guide rail for the hinges of the folding tarpaulin, allowing it to be opened and closed. Since folding is performed multiple times, this design, with its thickened area, effectively enhances the wear resistance and structural strength of the bending section and the locking protrusions, preventing deformation or wear caused by frequent sliding and ensuring the long-term stability of the unidirectional locking function. Simultaneously, the thickened design ensures more even force distribution at the groove opening, improving the smoothness of the tarpaulin's sliding, extending its overall service life, and ensuring reliable connection and flexible opening and closing even under complex working conditions.

[0015] In a further technical solution, the surface of the fourth plate is provided with a heightening portion, which is integrally connected between the surface of the fourth plate and the connecting end of the second plate and the third plate.

[0016] The above design makes the connection and transition between the fourth plate and the second and third plates smoother, effectively improving the overall rigidity of the structure.

[0017] A further technical solution is provided on the heightening part, which has a U-shaped groove formed by an inward indentation. The U-shaped groove is located on the side away from the receiving groove structure. The line connecting the center of the groove opening and the center of the groove bottom is parallel to the extension line in the length direction of the second plate. A U-groove block is provided at the end of the second plate away from the fourth plate. The inner wall contour of the U-groove block is U-shaped. The groove opening of the U-groove block is directly opposite the groove opening of the U-shaped groove. The U-groove block and the U-shaped groove on the heightening part are combined to form a fixed space for positioning the Velcro.

[0018] The above design ensures a more even distribution of force on the hook and loop fasteners during fastening, effectively preventing delamination caused by vibration or frequent opening and closing. The U-shaped groove and U-shaped block are positioned opposite each other to ensure consistent embedding depth at both ends of the hook and loop fasteners, improving the overall sealing and aesthetics of the structure.

[0019] In a further technical solution, the U-groove block is disposed at the connection end between the first plate and the second plate; the connection end between the first plate and the second plate is integrally connected to one end of the U-shaped opening of the U-groove block, and the inner wall of that end is flush with the surface of the second plate away from the triangular structure; the other end of the U-shaped opening of the U-groove block is disposed towards the side away from the first plate.

[0020] The above design makes the connection between the U-groove block and the first and second panels more stable, effectively avoiding the risk of cracking caused by stress concentration. At the same time, the design of the U-groove block can cooperate with the U-shaped channel to automatically limit the Velcro, preventing it from curling off due to wind or pulling during use.

[0021] The inner wall of the U-shaped opening end of the U-groove block is flush with the surface of the second plate away from the triangular structure, so that the surface is flat and seamless after the Velcro is attached, effectively avoiding the accumulation of foreign objects and wear.

[0022] In a further technical solution, the outer wall of the U-shaped groove block extends beyond the surface of the first plate away from the triangular structure; the plane containing the lowest point of the outer wall of the U-shaped groove block is parallel to the surface of the first plate away from the triangular structure, and there is a gap between the lowest point of the outer wall of the U-shaped groove block and the surface of the first plate away from the triangular structure.

[0023] The above design allows the spacer to be used to install shock-absorbing material, which can reduce noise during vehicle operation after the folding soft canopy frame is connected to the vehicle body; at the same time, it can also increase the sealing of the connection, making it dustproof and moisture-proof.

[0024] The outer wall of the U-shaped groove extends beyond the surface of the first plate away from the triangular structure. This is to make the U-shaped groove serve as a positioning reference during installation. At the same time, the first plate is fitted with the damping adhesive and installed behind the vehicle body. When viewed from the outside of the vehicle, only the profile itself is visible, which can hide the damping adhesive and increase the overall aesthetics.

[0030] The working principle and advantages of this utility model are as follows:

[0031] In this invention, a receiving groove structure composed of a fourth plate, a third plate, and a first plate can be used to accommodate the edge of the tarpaulin and achieve a slidable connection. The bent part and the locking protrusion form a limiting structure at the groove opening, allowing the tarpaulin to slide and fold along the bottom of the receiving groove when under force. There is no need to remove screws or add guide rails or sliders, which ensures the connection is stable and achieves a quick unfolding function, effectively reducing the cost of use and improving the ease of operation.

[0032] Unlike existing technologies, this utility model utilizes an integrated profile structure design, eliminating the need for additional installation components, significantly reducing material and assembly costs while improving structural strength and sealing performance.

[0045] See appendix Figure 1 - Figure 2 As shown, a folding soft top side rail profile for a pickup truck includes a profile body. Viewed in cross-section, the profile body includes a first plate 1, a second plate 2, and a third plate 3. The end of the first plate 1 is integrally connected to the end of the second plate 2, and the extension line of the first plate 1 along its length intersects the extension line of the second plate 2 along its length at an acute angle. The end of the third plate 3 is integrally connected to the end of the second plate 2 furthest from the first plate 1, and the other end of the third plate 3 is integrally connected to the surface of the first plate 1, forming a connection point 11 on the surface of the first plate 1. The second plate 2, the third plate 3, and the first plate 1 are positioned between the connection point 11 and the connection end between the first plate 1 and the second plate 2. The regions are combined to form a closed triangular structure; a fourth plate 4 is provided at the connection end of the second plate 2 and the third plate 3, and a bent portion 41 is provided at the end of the fourth plate 4 away from the triangular structure. The bent portion 41 is formed by bending the end of the fourth plate 4 away from the triangular structure towards the first plate 1 at a set angle. A locking protrusion 12 is provided on the surface of the first plate 1 and directly opposite the location of the bent portion 41; the regions of the fourth plate 4, the third plate 3 and the first plate 1 between the connection point 11 and the locking protrusion 12 are combined to form a receiving groove structure 6; the bent portion 41 and the locking protrusion 12 are located at the opening of the receiving groove structure 6, and the two cooperate with each other so that the size of the opening of the receiving groove structure 6 is smaller than the internal size of the receiving groove structure 6.

[0046] In this invention, the triangular structure is generally a right triangle, so that the accommodating groove structure 6 will not tilt or shake when containing bolts and other components.

[0047] In this utility model, the edge of the tarpaulin can be accommodated and slidably connected by the receiving groove structure 6 formed by the cooperation of the fourth plate 4, the third plate 3 and the first plate 1. The bent part 41 and the locking protrusion 12 form a limiting structure at the groove opening, so that the tarpaulin can slide and fold along the bottom of the receiving groove when under force, without the need to remove screws or add guide rail sliders. This ensures the connection is stable and achieves the function of quick unfolding and folding, effectively reducing the cost of use and improving the convenience of operation.

[0048] Unlike existing technologies, this utility model eliminates the need for additional installation components through an integrated profile structure design, significantly reducing material and assembly costs while improving structural strength and sealing performance. The presence of the receiving groove structure 6 ensures that the edge of the tarpaulin is stably limited after installation, preventing loosening or abnormal noise caused by vehicle vibration. At the same time, the design of the internal size of the receiving groove structure 6 being larger than the groove opening size ensures that the bending part 41 and the locking protrusion 12 can effectively form a one-way locking structure, facilitating the quick installation and positioning of the tarpaulin assembly.

[0049] It should be noted that the receiving groove structure 6 can be used with T-bolts to install stainless steel liners at both ends of the receiving groove structure 6, in order to reinforce the frame and the carriage (e.g., Figure 2 Furthermore, limiting blocks can be installed at both ends of the receiving groove structure 6 to limit the closed position of the folded tarpaulin. The edge of the tarpaulin can also be secured within the receiving groove structure 6 using T-screws. Figure 2 The image shows the main cross-section of the profile with the stainless steel lining installed; the edge of the tarpaulin can be positioned in the area between the stainless steel linings.

[0050] Preferably, both the bending portion 41 and the locking protrusion 12 are provided with a thickened area 411 of equal thickness, the thickness of which is greater than the thickness of the first plate 1 and / or the fourth plate 4.

[0051] The receiving groove structure 6 acts as a guide rail for the hinge of the folding tarpaulin, allowing it to be opened and closed. Since folding operations are performed multiple times, the thickened area 411, thanks to the above design, effectively enhances the wear resistance and structural strength of the bending part 41 and the locking protrusion 12, preventing deformation or wear caused by frequent sliding and ensuring the long-term stability of the unidirectional locking function. Simultaneously, the thickened design makes the force at the groove opening more even, improving the smoothness of the tarpaulin's sliding, extending its overall service life, and ensuring reliable connection and flexible unfolding even under complex working conditions.

[0052] Preferably, the surface of the fourth plate 4 is provided with a heightening portion 42, which is integrally connected between the surface of the fourth plate 4 and the connecting end of the second plate 2 and the third plate 3.

[0053] The above design makes the connection between the fourth plate 4 and the second plate 2 and the third plate 3 smoother, effectively improving the overall rigidity of the structure.

[0054] Preferably, the heightening part 42 is provided with a U-shaped groove 421 formed by an inward indentation. The U-shaped groove 421 is located on the side away from the receiving groove structure 6. The line connecting the center of the groove opening and the center of the groove bottom of the U-shaped groove 421 is parallel to the extension line in the length direction of the second plate 2. The end of the second plate 2 away from the fourth plate 4 is provided with a U-shaped groove block 21. The inner wall contour of the U-shaped groove block 21 is U-shaped. The groove opening of the U-shaped groove block 21 is directly opposite the groove opening of the U-shaped groove 421. The U-shaped groove block 21 and the U-shaped groove 421 on the heightening part 42 are combined to form a fixed space 5 for positioning the Velcro.

[0055] The above design ensures a more even distribution of force on the hook and loop fasteners during fastening, effectively preventing delamination caused by vibration or frequent opening and closing. The U-shaped groove 421 and the U-groove block 21 are positioned opposite each other to ensure that the embedding depth of the hook and loop fasteners is consistent at both ends, improving the overall sealing performance and aesthetics of the structure.

[0056] Preferably, the U-groove block 21 is disposed at the connection end between the first plate 1 and the second plate 2; the connection end between the first plate 1 and the second plate 2 is integrally connected to one end of the U-shaped opening of the U-groove block 21, and the inner sidewall of the latter end is flush with the surface of the second plate 2 away from the triangular structure; the other end of the U-shaped opening of the U-groove block 21 is disposed towards the side away from the first plate 1.

[0057] The elevation at this location can be referenced. Figure 1 .

[0058] The above design makes the connection between the U-groove block 21 and the first plate 1 and the second plate 2 more stable, effectively avoiding the risk of cracking caused by stress concentration. At the same time, the design of the U-groove block 21 can cooperate with the U-shaped groove 421 to automatically limit the Velcro, preventing it from curling off due to wind or pulling during use.

[0059] The inner wall of the U-shaped opening end of the U-groove block 21 is flush with the surface of the second plate 2 away from the triangular structure, so that the surface is flat and seamless after the Velcro is attached, effectively avoiding the accumulation of foreign objects and wear.

[0060] Preferably, the outer wall of the U-groove block 21 extends beyond the surface of the first plate 1 away from the triangular structure; the plane containing the lowest point of the outer wall of the U-groove block 21 is parallel to the surface of the first plate 1 away from the triangular structure, and there is a gap 211 between the lowest point of the outer wall of the U-groove block 21 and the surface of the first plate 1 away from the triangular structure.

[0061] The above design allows the space 211 to be used to install shock-absorbing material, which can reduce noise during vehicle operation after the folding soft canopy frame is connected to the vehicle body; at the same time, it can also increase the sealing of the connection, making it dustproof and moistureproof.

[0062] The outer wall of the U-groove block 21 extends beyond the surface of the first plate 1 away from the triangular structure so that the U-groove block 21 can serve as a positioning reference during installation. At the same time, the first plate 1 is attached to the damping adhesive and installed behind the vehicle body. When viewed from the outside of the vehicle, the profile itself is still visible, which can hide the damping adhesive and increase the overall aesthetics.

[0063] Working principle:

[0064] First, the shock-absorbing adhesive is fixed in the interval 211. Then, the first plate 1 is positioned on the vehicle body. Subsequently, the inner stainless steel lining is installed through the cooperation of the receiving groove structure 6 and the T-shaped screw, making the connection between the profile body and the car body tighter. Then, the Velcro is inserted into the fixing space 5. At this time, the two ends of the Velcro are symmetrically clamped by the U-shaped groove 421 and the U-groove block 21 to ensure consistent embedding depth and uniform force.

[0065] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
