Description

Technical Field

[0001] The utility model relates to the field of wing-opening cargo boxes, in particular to a retractable door structure of a wing-opening cargo box. Background Art

[0002] There are two common types of gas strut wing-opening cargo boxes on the market: one with a gas strut door panel that cannot be retracted into the cargo box, and one with a gas strut door panel that requires the gas strut to be removed before the door panel can be retracted into the cargo box. However, both types of cargo boxes have disadvantages:

[0003] 1. The door panel of the gas strut cannot be retracted into the wing-opening cargo box inside the compartment. After the door panel is opened, it occupies a large area and has certain requirements on the use site, which is inconvenient for users to use.

[0004] 2. As for the gas struts, when the door panels need to be retracted into the compartment, the gas struts must be removed so that the door panels can be extended and retracted to the wing-opening cargo box inside the compartment. Users also need to disassemble the gas struts according to their needs when using it, which is very troublesome to use. Utility Model Content

[0005] The utility model aims to provide a retractable door structure of a wing-opening cargo box, which can conveniently retract the door panel after it is opened.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical solution: a retractable door structure for a wing-opening cargo box, comprising a door frame, a gas strut and a door panel, wherein a slide assembly and a slider are provided on the door panel, a limiting area and a sliding area are formed in the slide assembly, the lower end of the gas strut is hinged to the door frame, and the upper end of the gas strut is hinged to the slider, and the gas strut is used to push open the door panel;

[0007] In the initial state, the door panel is arranged vertically, the upper side of the door panel is hinged to the door frame, the slider is located in the limit zone, and the slider and the slide assembly are relatively stationary;

[0008] After the door panel is pushed open, the door panel is lifted, the slider enters the sliding area, and the slider and the slide groove assembly slide relative to each other.

[0009] The beneficial effects of this program are:

[0010] 1. In the prior art, the door panel cannot retract after being opened. The reason is that during the process of pushing the door panel open, the connection position between the door panel and the gas strut remains fixed to facilitate door opening. However, this also causes the door panel to be unable to slide after being pushed open.

[0011] In order to solve the above problems, the inventor has developed the present utility model, which can not only push open the door panel, but also realize the sliding and contraction of the door panel; that is, it saves space and is easy to operate.

[0012] 2. In the initial state, the slide is located in the limit area, ensuring that the connection position between the door panel and the gas strut remains fixed, so that the gas strut can push the door panel open; after the door panel is pushed open, lift the door panel to move the slider downward relative to the door panel, so that the slider enters the sliding area, so that the slider and the slide groove assembly can slide relative to each other, thereby sliding the door panel horizontally into the cargo box, thereby saving space.

[0013] 3. In summary, in this solution, the wing with gas struts can be used to open the cargo box, and the door panels can be put into the box without removing the gas struts.

[0014] Furthermore, the slider includes a connecting portion and a sliding portion, and the sliding portion is wider than the connecting portion;

[0015] The slide assembly includes an upper slide and a lower slide. The upper slide is provided with a vertically penetrating strip-shaped connecting groove. The width of the connecting groove is larger than the connecting part and smaller than the sliding part. A slide corresponding to the connecting groove is opened on the upper side of the lower slide. A limiting groove is provided at the end of the slide. The depth of the limiting groove is greater than the slide. Both the limiting groove and the slide are used to accommodate the sliding part of the slider. The limiting area is in the limiting groove, and the sliding area is in the slide.

[0016] Furthermore, the upper slide plate is composed of two strip plates, and the two strip plates are detachably connected to the upper sides of the lower slide plate respectively, and the connecting groove is the gap between the two strip plates.

[0017] Furthermore, the limiting groove vertically passes through the lower slide plate.

[0018] Furthermore, when the gas strut reaches the maximum stroke, the door panel tilts downward away from the side of the gas strut.

[0019] Furthermore, a bearing is rotatably provided on the upper side of the door panel, and a guide rail is horizontally provided on the upper end of the door frame, and the guide rail is used to slide and rotate with the bearing.

[0020] This solution also has the following effects:

[0021] 1. In the initial state, the sliding part of the slider is in the limit groove, and the gas strut is tilted;

[0022] Then, the gas strut presses against and pushes the door panel, the sliding part is always in the limit groove, and the upper side of the door panel and the bearing rotate relative to each other;

[0023] Next, the stroke of the gas strut reaches its maximum, lifting the door panel upward to a horizontal level so that the upper end of the gas strut no longer contacts the door panel, allowing the slider at the upper end of the gas strut to enter the slide groove, thereby pushing the door panel, causing the door panel's bearing to slide on the guide rail, and causing the slider to slide in the slide groove, thereby retracting the door panel horizontally into the cargo box.

[0024] On the contrary, when closing the door, pull out the door panel, so that the slider slides to the end of the slide groove and enters the limit groove, and then the gas strut retracts to drive the door panel to close.

[0025] 2. The slider consists of two strip plates, which are easy to disassemble and replace.

[0026] 3. The width of the connecting groove is larger than the connecting part and smaller than the sliding part, thereby preventing the sliding part of the slider from falling out of the sliding groove.

[0027] 4. The limit groove vertically penetrates the lower slide plate, thereby ensuring that the limit groove depth is maximized and the depth difference between the limit groove and the slide groove is maximized, thereby improving the reliability of the limit groove's limiting effect and preventing the sliding part in the limit groove from directly sliding into the slide groove due to accidental vibration.

[0038] The embodiment is basically as follows Figure 1-Figure 7 As shown: a retractable door structure of a wing-opening cargo box, including a door frame, a door panel 2 and two gas struts 3. In this embodiment, the gas struts 3 are pneumatic struts.

[0039] like Figure 1 As shown, the door frame includes two doorposts 1, which are respectively arranged on both sides of the door panel 2. Figure 1The upper right side is the outside of the cargo box, that is, the opposite direction of the door opening, and the opposite direction is the inside of the cargo box. The middle part of the door column 1 is bolted to a connecting piece 11, which is hinged to the bottom of the gas strut 3. In this embodiment, the two structures are hinged in the following way: one of the structures is provided with a latch, which passes through the other structure and is rotatably connected to the structure; the upper end of the door column 1 is horizontally bolted to a guide rail 12 for ease of display. Figure 1 Only the guide rail 12 on one of the door posts 1 is shown. The guide rail 12 is concave, and the openings of the two guide rails 12 are horizontally opposite to each other. A bearing (not shown in the figure) is slidingly provided in the guide rail 12. In this embodiment, the bearing is a ball bearing.

[0040] A rotating shaft is welded on the upper side of the door panel 2, and bearings are inserted into the two ends of the rotating shaft and are rotatably connected to the bearings; the left and right sides of the inner side of the door panel 2 (towards the inner side of the cargo box) are respectively connected with a strip-shaped slide 54 component by vertical bolts, and the slide 54 components are provided with sliders 4; the sliders 4 include an integrally formed connecting portion 41 and a sliding portion 42, the sliding portion 42 is a rectangular plate parallel to the door panel 2, and the connecting portion 41 is perpendicular to the sliding portion 42, such as Figure 1 In the plate-like structure shown, the width of the sliding portion 42 is greater than that of the connecting portion 41 ; in this embodiment, the width directions of the slider 4 and the slide groove 54 assembly are perpendicular to the length direction of the slide groove 54 assembly and are parallel to the door panel 2 .

[0041] like Figure 4-Figure 7 As shown, the right side of the slide 54 assembly is the side connected to the door panel 2. The slide 54 assembly includes an upper slide and a lower slide 53. The upper slide is composed of two strip plates 51. The two strip plates 51 are respectively bolted to the upper side of the lower slide 53. The gap between the two strip plates 51 forms a connecting groove 52. The width of the connecting groove 52 is greater than the width of the connecting portion 41 and less than the width of the sliding portion 42. Figure 6 As shown, a strip-shaped slide groove 54 corresponding to the connecting groove 52 is opened on the upper side of the lower slide plate 53. Figure 4 、 Figure 5 As shown, the two ends of the chute 54 are respectively provided with limiting grooves 55, the depth of the limiting grooves 55 is greater than the chute 54 and vertically passes through the lower slide 53, as shown in FIG. Figure 7 As shown, the limiting groove 55 and the sliding groove 54 are both used to accommodate the sliding portion 42 of the slider. The limiting groove 55 is a limiting area, and the sliding groove 54 is a sliding area.

[0042] The upper end of the gas strut 3 is hinged to the connecting portion 41 of the slider 4. The gas strut 3 is used to push open the door panel 2. When the gas strut 3 reaches its maximum stroke, the door panel 2 tilts downward away from the side of the gas strut 3.

[0043] A method of using a retractable door structure of a wing-opening cargo box is as follows:

[0044] 1. Such as Figure 1As shown, in the initial state, the door panel 2 is arranged vertically, the gas strut 3 is arranged obliquely, the slider 4 is located in the limiting groove 55 at the upper end of the slide 54, and the slider 4 and the slide 54 components are relatively stationary;

[0045] 2. Such as Figure 2 As shown, the stroke of the gas strut 3 reaches its maximum, pushing the door panel 2 open, and the door panel 2 rotates around the axis. At this time, the door panel 2 has not yet rotated to the horizontal position. Then, the door panel 2 is manually lifted to the horizontal position so that the upper end of the gas strut 3 no longer abuts against the door panel 2, thereby allowing the slider 4 at the upper end of the gas strut 3 to enter the slide groove 54.

[0046] 3. Such as Figure 3 As shown, next, the door panel 2 is pushed horizontally so that the bearing of the door panel 2 slides on the guide rail 12 and the slider 4 slides in the slide groove 54, thereby retracting the door panel 2 horizontally into the cargo box and reducing the space occupied by the door panel 2.
