Description

Technical Field

[0001] The utility model relates to the technical field of truck manufacturing, in particular to a cargo box door panel sealing structure. Background Art

[0002] Common open door structure cargo boxes on the market, such as Figure 2 As shown, the manufacturer will reserve a gap between the door panel and the door frame (the cross section at the rear end of the cargo box) to facilitate the frequent opening and closing of the door panel. However, if the reserved gap is too large, liquids or powders and other goods will be spilled, causing environmental pollution and economic losses. If the reserved gap is too small, the cargo box will deform over time, causing difficulties in opening and closing the door panel during use. Such problems seriously restrict the convenience of using the vehicle, increase operating costs, reduce attendance efficiency, and pose safety hazards. When the reserved gap is larger, it has obvious advantages in terms of service life and processing costs. Based on this, this solution designs a solution to deal with a larger reserved gap.

[0025] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0028] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0029] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0030] like Figure 2 The door panel 2 structure in the prior art shown is hinged on the side of the rear part of the cargo box 1. The door panel 2 is flipped horizontally to open or close, and a locking assembly 3 is provided on the other side to lock the closed door panel 2. A U-shaped gap 8 is formed between the door panel 2 and the U-shaped cargo box 1.

[0031] like Figure 1 The figure shows the closed structure of the cargo box 1 door panel 2 of the present solution, which includes a cargo box 1 with a U-shaped cross section, a door panel 2 hinged to the side of the rear of the cargo box 1 to close the cargo box 1, and a locking assembly 3 (the locking assembly 3 is a prior art and is not shown in the figure) arranged at the rear of the cargo box 1 to lock the door panel 2 in a closed state. In order to prevent the cargo from leaking from the gap 8, an edge of the door panel 2 is provided to block the gap 8.

[0032] like Figure 3 , Figure 4 As shown, the rear of the cargo box 1 is provided with a hinge 4, a hinge plate 5 is fixedly connected to the door panel 2, and the outgoing side includes a first baffle 6 and a second baffle 7. The first baffle 6 is provided at the bottom of the door panel 2 and at the side of the door panel 2 close to the locking assembly 3, and the second baffle 7 is provided at the side of the door panel 2 close to the hinge 4. The second baffle 7 covers the gap 8 on the side of the door panel 2 except the hinge plate 5. By closing the door panel 2, the first baffle 6 and the second baffle 7 are driven to abut against the gap 8 to complete the sealing of the cargo box 1.

[0033] In one embodiment, the second baffle 7 is made of a flexible material, such as a flexible, foldable and bendable material, to avoid interference between the second baffle 7 and the rear side of the cargo box 1 when the second baffle 7 rotates with the door panel 2 .

[0034] Although the flexible material can avoid the interference between the second baffle 7 and the cargo box 1, it is easy to wear after repeated use. Therefore, in another embodiment, the second baffle 7 is designed to be a non-flexible structure that can slide laterally: the outer side of the second baffle 7 is connected to a connecting plate 9 covering all the second baffles 7, and the inner side of the connecting plate 9 is provided with a pulley 10, which slides on the top of the hinge plate 5, and a limit block 11 is provided on the door panel 2 to limit the second baffle 7 to make it slide laterally. The connecting plate 9 and the second baffle 7 form a whole, and slide laterally in the limit blocks 11 on the upper and lower sides. The second baffle 7 moves along the Figure 3 After moving to the left, the second baffle 7 loses the coverage of the gap 8 and leaves enough space, the door panel 2 can rotate around the hinge 4, and the second baffle 7 will not interfere with the cargo box 1. When the door panel 2 is closed, the second baffle 7 moves to the right to cover the gap 8.

[0035] Preferably, the hinge plate 5 is provided with limit columns 13 located on both sides of the second baffle plate 7. When the second baffle plate 7 moves to both ends, it is blocked and stopped by the limit columns 13, and an elastic pin can be provided on the limit block 11 or the connecting plate 9 to lock the movement of the second baffle plate 7.

[0036] Since the door panel 2 structure is in an outdoor environment for a long time, debris will accumulate at the pulley 10 to hinder sliding. For the convenience of cleaning, the present invention sets a limit column 13 on the side away from the hinge 4 at the bottom of the hinge plate 5, so that the sliding track of the pulley 10 is unobstructed and the debris on the track can be easily cleaned outward along the track.

[0037] Specifically, the side of the second baffle plate 7 is connected to a fixing plate 12 located above the hinge plate 5, the connecting plate 9 is fixed to the fixing plate 12 and the second baffle plate 7 respectively with bolts, and the fixing plate 12 fills the top of the pulley 10, so that debris is not easy to enter the track.

[0038] Preferably, the inner surface of the second baffle 7 is provided with a smooth wear-resistant layer, which saves effort in sliding and ensures the sealing effect of the gap 8.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
