Description

Technical Field

[0001] The utility model relates to the technical field of cargo box cover equipment, and in particular to an installation system for a pickup truck cargo box cover. Background Art

[0002] Pickup trucks are a type of automobile that are popular because of their open cargo boxes that can hold a large amount of cargo. However, a disadvantage is that most pickup trucks are not equipped with shelters. In rainy and snowy weather, rainwater will flow into the cargo box and make the cargo damp, rendering the cargo unusable and causing a large amount of economic losses. Therefore, in the prior art, models with open cargo boxes need to be equipped with an openable cargo box cover to protect and shield the cargo in the cargo box.

[0003] In the prior art, the connection between the cargo cover and the cargo box relies on a mounting system, wherein the most common mounting system is two side rails connected to the two side walls of the pickup truck cargo box. Since the cargo cover on the pickup truck is generally installed laterally, the side rails in the existing mounting system are all detachably mounted on the side walls of the pickup truck cargo box, and then the cargo cover is installed on the pickup truck cargo box by connecting with the side rails.

[0004] Among them, the Chinese patent with patent number ZL202021780483.9 discloses: "A split waterproof fixing frame for a car compartment cover, comprising a frame body, the frame body being fixed to the inner side of the car compartment side panel, the frame body comprising a mounting surface, a support made of a flexible sealing material being provided on the mounting surface, the upper end of the support being in contact with the car compartment cover, the contact point between the support and the car compartment cover being higher than the mounting surface, and a stop surface being provided on the side of the mounting surface away from the support. The flexible support reduces the wear between the support and the car compartment cover, improves the service life, and can also prevent the ingress of water into the car compartment caused by the accumulation of rainwater. At the same time, after the support and the frame body are processed separately, the strength of the frame body is improved, while the processing difficulty is reduced and the production cost is reduced."

[0005] However, including the solutions described in the above-mentioned patents, there is a problem with the existing installation systems for cargo box covers on the market, that is, the connection method between the existing installation system and the cargo box side wall is to use clips to clamp the side rails and the cargo box side wall to achieve a fixed connection between the two. However, in this connection method, since the clips themselves have gravity, the clips will gradually slide down under the action of gravity after long-term use, which may cause the clips to detach and the connection between the side rails and the cargo box side wall to be released; and in the installation process of the side rails, since multiple clips are needed for fixation, it is necessary to adjust the spacing between the clips to ensure the uniformity of the action points, but when the clips are clamped between the side rails and the cargo box side wall, their position cannot be adjusted, so the position of the clips needs to be accurately planned in advance to avoid the need for adjustment, but this makes the method of fixing with clips very inconvenient to assemble and disassemble. Summary of the Invention

[0014] Furthermore, the second sliding portion is configured as a slider connected to the side of the connecting member, and the slider is slidably arranged in the slide rail. The connecting member and the slider are connected by a second fastener, and the second fastener is threadedly engaged with the slider. By tightening the second fastener, the slider can be pressed against the slide rail to prevent the connecting member from sliding relative to the slide rail.

[0015] Furthermore, the first sliding portion is configured as a "T"-shaped protrusion located on the top of the connecting member, and the "T"-shaped protrusion is plugged into the first sliding groove;

[0016] The "T"-shaped protrusion includes fins located on both sides of its top, and the slot of the first slide groove is bent inward to form a first slot edge. The fins are against the first slot edge to prevent the "T"-shaped protrusion from detaching from the first slide groove.

[0017] Furthermore, a first groove is provided on the lower side of the fin plate of the "T"-shaped protrusion, and a convex edge is provided on the edge of the first groove protruding upward, and a snap fit is formed between the convex edge and the first groove.

[0018] Furthermore, the notch of the second chute is bent inward to form a second chute edge, and the distance between the second chute edges on both sides of the second chute is smaller than the width of the slider to prevent the slider from escaping from the second chute.

[0019] Furthermore, the slide rail is connected to the inner side of the cargo box side wall through a third fastener, the head of the third fastener is located in the second slide groove, and the slider is also provided with a second groove for avoiding the head of the third fastener.

[0020] Furthermore, the first slide groove also includes a first lateral opening located at both ends thereof, and the first sliding part can enter or exit the first slide groove through the first lateral opening; the second slide groove also includes a second lateral opening located at both ends thereof, and the second sliding part can enter or exit the second slide groove through the second lateral opening.

[0021] Furthermore, the side rails further include a skirt portion, the skirt portion is located above the top of the cargo box side wall, and a first sealing strip is further provided between the skirt portion and the cargo box side wall;

[0024] Furthermore, the top inner sides of both ends of the cargo box side walls are provided with bumps protruding toward the cargo box, and gaps are left between the two end surfaces of the slide groove portion and the two end surfaces of the side rails for avoiding the bumps.

[0025] The assembly method of the utility model is as follows: first, the slide rail is connected to the inner side of the cargo box side wall through the third fastener;

[0026] Then, assemble the several sliders needed to the slide rail from the second side opening, and then assemble the "T"-shaped protrusion on the top of the connecting piece to the slide groove of the side rail through the first side opening. Then, move the entire side rail connected to the connecting piece on its lower side to the top of the cargo box side wall, and align the skirt of the side rail with the top of the cargo box side wall. At this time, you can put a sealing strip between the skirt of the side rail and the top of the cargo box side wall, and then you can lower the side rail so that the skirt of the side rail abuts against the top of the cargo box side wall through the sealing strip. At this time, the side rail has been suspended and connected to the cargo box side wall.

[0027] Finally, the side rails are fixed to the side walls of the cargo box. First, the connector is slid along the first slide groove to adjust the spacing between the connectors until the connectors are evenly distributed. Then, the first fastener engaged with the connector is tightened so that the first fastener is pressed against the side cabinet to fix the relative position of the connector and the side rails. Next, several sliders that have been pre-installed on the slide rails are slid so that each slider is aligned with a connector. Then, the second fastener is passed through the connector and threaded onto the slider to connect the slider and the connector. Then, by tightening the second fastener, the slider moves toward the notch of the second slide groove under the action of threaded engagement, and finally presses against the edge of the second groove, thus fixing the relative position of the slider relative to the slide groove. Due to the connection between the slider and the connector, the connector is also fixed relative to the slide groove. Furthermore, the side rails, connector, slider, slide rail and cargo box side wall are all fixed relative to each other through the connection, completing the assembly of the mounting system on the cargo box side wall.

[0028] The disassembly method of the present invention: On the basis of the above-mentioned installation method, when it is necessary to disassemble the installation system on the side wall of the cargo box, the second fastener can be unscrewed and removed from between the connecting piece and the slider, so that the connection between the slider and the connecting piece can be released. At this time, the entire side rail together with the connecting piece thereon can be removed from the side wall of the cargo box, and then the slide rail can be removed from the side wall of the cargo box by unscrewing the third fastener, thereby completing the disassembly of the entire installation system.

[0029] The adjustment method of the present invention is as follows: when the installation system is completed or it is found that the positions of the various connecting parts are deviated after a period of use, the first fastener and the second fastener can be loosened, and then the connecting part can be moved. The "T"-shaped protrusion on the top of the connecting part slides along the first slide groove, and the slider slides along the stop slide groove with the connecting part. When the connecting part is moved into place, the first fastener and the second fastener can be retightened.

[0030] The beneficial effects of the present invention are:

[0031] 1. A first slide groove is provided on the side rail, and a second slide groove is provided on the inner side of the cargo box side wall. The connecting piece is slidably connected to both the first slide groove and the second slide groove.

[0068] Assembly method of this embodiment: First, connect the slide rail 3 to the inner side of the cargo box side wall 4 through the third fastener 303;

[0069] Then, several sliders 204 needed are assembled to the slide rail 3 through the second side opening 304, and then the "T"-shaped protrusion 206 on the top of the connecting piece 2 is assembled to the slide groove portion 102 of the side rail 1 through the first side opening 106. Then, the entire side rail 1 connected to the connecting piece 2 on its lower side is moved to the top of the cargo box side wall 4, and the skirt portion 107 of the side rail 1 is aligned with the top of the cargo box side wall 4. At this time, a sealing strip can be placed between the skirt portion 107 of the side rail 1 and the top of the cargo box side wall 4. Then, the side rail 1 can be lowered, so that the skirt portion 107 of the side rail 1 abuts against the top of the cargo box side wall 4 through the sealing strip. At this time, the side rail 1 has been suspended and connected to the cargo box side wall 4.

[0070] Finally, the fixation between the side rail 1 and the side wall 4 of the cargo box is completed. First, slide the connector 2 along the first slide groove 103 to adjust the spacing between each connector 2 until each connector 2 is evenly distributed. Then, the first fastener 203 engaged with the connector 2 can be tightened so that the first fastener 203 is pressed against the side cabinet to achieve the relative position fixation between the connector 2 and the side rail 1.

Then, the second fastener 205 can be passed through the connector 2 and threaded on the slider 204 to achieve sliding. The connection between the block 204 and the connecting member 2 is then achieved by tightening the second fastener 205. The slider 204 moves toward the notch of the second slide groove 301 under the action of threaded cooperation, and finally makes the slider 204 press against the second groove edge 302. At this point, the relative position of the slider 204 relative to the slide groove is fixed. Due to the connection between the slider 204 and the connecting member 2, the position of the connecting member 2 is also fixed relative to the slide groove. Furthermore, at this time, the side rail 1, the connecting member 2, the slider 204, the slide rail 3 and the cargo box side wall 4 are all fixed in relative position through the connection, completing the assembly of the installation system on the cargo box side wall 4.

[0071] The disassembly method of this embodiment: Based on the above-mentioned installation method, when it is necessary to disassemble the installation system on the cargo box side wall 4, the second fastener 205 can be unscrewed and removed from between the connector 2 and the slider 204, so that the connection between the slider 204 and the connector 2 can be released. At this time, the entire side rail 1 together with the connector 2 thereon can be removed from the cargo box side wall 4, and then the slide rail 3 can be removed from the cargo box side wall 4 by unscrewing the third fastener 303, completing the disassembly of the entire installation system.

[0072] The adjustment method of this embodiment: When the installation system is completed or it is found that the positions of the various connecting parts 2 are deviated after being used for a period of time, the first fastener 203 and the second fastener 205 can be loosened, and then the connecting part 2 can be moved. The "T"-shaped protrusion 206 on the top of the connecting part 2 slides along the first slide groove 103, and the slider 204 slides along the stop slide groove with the connecting part 2. When the connecting part 2 is moved into place, the first fastener 203 and the second fastener 205 can be retightened.

[0073] The advantages of this embodiment are that the connectors are slidably connected to the side rails and the side walls of the cargo box, respectively, making the connection between the side rails and the side walls of the cargo box more secure while also simplifying and facilitating assembly and disassembly of the side rails from the side walls of the cargo box. The above specific embodiments are merely illustrative of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art may make modifications to the present embodiment as needed, even if they do not contribute to any creative innovation. However, as long as they fall within the scope of the claims of the present invention, they will be protected by patent law.
