Description

Technical Field

[0001] This invention relates to the field of van technology, specifically to a van panel splicing structure and a van. Background Technology

[0002] During the transportation process, the box truck's panels will inevitably be affected by the impact of the goods. Therefore, the panel structure needs to have a certain strength. At the same time, in order to ensure the safety of the goods inside the box, the panels also need to have a certain degree of waterproof and sealing performance.

[0003] Currently, the main body panel structures include corrugated sheet welding, cold-pressed riveting of flat steel plates, and straight-seam welding of flat steel plates. Among these, corrugated sheets increase wind resistance; cold-pressed riveting of flat steel plates limits material strength; and while straight-seam welding of flat steel plates can solve the problems of strength and waterproofing, it has low production efficiency, high energy consumption, and the welding itself causes large deformation, which is not conducive to the production of thin plates. The unevenness caused by deformation will be reflected on the exterior surface of the vehicle, affecting its appearance.

[0004] Therefore, it is essential to develop a new type of panel structure. Summary of the Invention

[0005] The purpose of this invention is to provide a van panel splicing structure and a van, so as to solve the problems existing in the panel structure of the prior art.

[0006] To achieve the above objectives, the first aspect of the present invention discloses a van body panel splicing structure, comprising a plurality of connecting units arranged and fixed in a transverse direction. Each connecting unit includes a connecting plate and a first connecting head and a second connecting head respectively disposed on both sides of the connecting plate. The first connecting head and the second connecting head are both disposed on the side of the connecting plate facing inward, and the first connecting head and the second connecting head are matched and disposed. Adjacent connecting units are connected through the first connecting head and the second connecting head, and a fixing layer and a sealing layer are provided between the connected first connecting head and the second connecting head.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] This invention employs several connecting units spliced ​​and fixed to form a compartment panel. Each connecting unit includes a connecting plate and matching first and second connectors on both sides of the connecting plate. A fixing layer is provided between the first and second connectors to fix adjacent connecting units. Both the first and second connectors are located on the side of the connecting plate facing inwards, so the connecting plates of adjacent connecting units can form a complete plane. At the same time, a sealing layer is provided at the connection point, which can effectively separate the internal and external environments of the compartment. Furthermore, the matching first and second connectors can increase the fixing surface size of adjacent connecting units and improve connection stability. It is applicable to materials such as ordinary carbon steel, high-strength steel, aluminum, and stainless steel, and greatly reduces production costs and consumables. It is particularly suitable for large-scale industrial production and the construction of unmanned production lines.

[0009] Based on the above technical solution, the present invention can be further improved as follows:

[0010] Furthermore, the sealing layer includes an external adhesive layer disposed at the gap between adjacent connecting plates, the external adhesive layer extending from the bottom to the top to seal the connection area of ​​the first connector and the second connector.

[0011] By adopting the above solution, the connection area of ​​the first connector and the second connector is sealed by the external adhesive layer, which effectively isolates the environment inside and outside the compartment, and at the same time provides a certain degree of protection for the fixing layer.

[0012] Furthermore, the sealing layer includes a sealing strip disposed between the first connector and the second connector, the sealing strip extending vertically from the bottom end to the top end of the connecting surfaces of the first connector and the second connector to seal the connecting surfaces of the first connector and the second connector.

[0013] Furthermore, a pair of sealing strips are provided between the first connector and the second connector, and the pair of sealing strips are symmetrically arranged on both sides of the fixing layer.

[0014] By adopting the above solution, a pair of sealing strips set on both sides of the fixed layer effectively isolate moisture inside and outside the compartment, while also preventing the fixed layer from being affected by the external environment, improving connection stability and sealing effect at the connection point, and is suitable for vans with high waterproof requirements.

[0015] Furthermore, the first connector includes a first inner flange and a first outer extension edge arranged in an L-shape. The first inner flange is connected to one side of the connecting plate and extends inward, while the first outer extension edge extends away from the connecting plate. The second connector includes a second inner flange and a second inner extension edge arranged in an L-shape. The second inner flange is connected to the other side of the connecting plate and extends inward, while the second inner extension edge extends towards the inside of the connecting plate. The sealing strip and the fixing layer are disposed between the inner side of the first inner flange and the outer side of the second inner flange, and the inner side of the first outer extension edge and the outer side of the second inner extension edge are closely fitted together.

[0016] By adopting the above scheme, both the first connector and the second connector are located on the inner side of the connecting plate, thereby avoiding affecting the flatness of the panel appearance. A pair of sealing strips and fixing layers are set between the first inner flange and the second inner flange to effectively isolate moisture from the outside. At the same time, the inner side of the first outer extension and the outer side of the second inner extension are closely attached to each other, which facilitates positioning during installation and further improves the sealing effect inside the box.

[0017] Furthermore, a pair of sealing strips are symmetrically arranged at both ends of the inner side of the first inner flange and are tightly sealed to the second inner flange, and the fixing layer is arranged in the middle of the inner side of the first inner flange and is connected and fixed to the second inner flange.

[0018] By adopting the above solution, sealing strips are installed at both ends of the inner side of the first inner flange, which can seal the area between the first inner flange and the second inner flange, directly isolating water vapor outside the panel and improving the sealing effect.

[0019] Furthermore, the fixing layer is a spot weld layer that is evenly spaced vertically between the first inner flange and the second inner flange.

[0020] Furthermore, the sealing strip is a double-sided adhesive strip.

[0021] By adopting the above solution, double-sided adhesive strips are easy to operate manually, do not require high operator skills, are easier to implement in automated production lines, effectively reduce labor intensity, and are inexpensive.

[0022] Furthermore, the connecting plate, the first connector, and the second connector are integrally formed.

[0023] By adopting the above solution, the structural strength and sealing performance can be further improved.

[0024] The second aspect of the present invention also discloses a van that adopts the above-mentioned van panel splicing structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of the present invention, "plurality" means more than two, unless otherwise specifically defined.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] Example 1:

[0047] like Figure 1-4 As shown in the figure, the van panel splicing structure provided in this embodiment includes several connecting units that are arranged and fixed in a horizontal direction.

[0048] Each connection unit includes a connection plate 1 and a first connection head 2 and a second connection head 3 respectively arranged on both sides of the connection plate 1. The second connection head 3 is matched with the first connection head 2. Adjacent connection units are connected through the first connection head 2 and the second connection head 3.

[0049] The connecting plate 1, the first connector 2, and the second connector 3 are integrally formed to improve structural strength and sealing performance.

[0050] A pair of sealing strips 4 and a fixing layer are provided between the first connector 2 and the second connector 3 that are connected. The pair of sealing strips 4 are both set vertically from the bottom end to the top end of the connecting surface of the first connector 2 and the second connector 3. The fixing layer is set between the pair of sealing strips 4 to connect and fix the first connector 2 and the second connector 3.

[0051] Specifically, the first connector 2 includes an L-shaped first inner flange 201 and a first outer extension 202. The first inner flange 201 is connected to one side of the connecting plate 1 and extends inward, while the first outer extension 202 extends away from the connecting plate 1. The second connector 3 includes an L-shaped second inner flange 301 and a second inner extension 302. The second inner flange 301 is connected to the other side of the connecting plate 1 and extends inward, while the second inner extension 302 extends towards the inside of the connecting plate 1. The sealing strip 4 and the fixing layer are disposed between the inner side of the first inner flange 201 and the outer side of the second inner flange 301, and the inner side of the first outer extension 202 and the outer side of the second inner extension 302 are tightly fitted together.

[0052] Both the first connector 2 and the second connector 3 are located on the inner side of the connecting plate 1, thereby avoiding affecting the flatness of the panel appearance. A pair of sealing strips 4 and a fixing layer are set between the first inner flange 201 and the second inner flange 301 to effectively isolate moisture from the outside. At the same time, the inner side of the first outer extension 202 and the outer side of the second inner extension 302 are closely attached to each other, which facilitates positioning during installation and further improves the sealing effect inside the box.

[0053] A pair of sealing strips 4 are symmetrically arranged at both ends of the inner side of the first inner flange 201 and are tightly sealed to the second inner flange 301. The fixing layer is arranged in the middle of the inner side of the first inner flange 201 and is connected and fixed to the second inner flange 301.

[0054] Sealing strips 4 are provided at both ends of the inner side of the first inner flange 201, which can seal the area between the first inner flange 201 and the second inner flange 301, directly isolating water vapor outside the panel and improving the sealing effect.

[0055] The fixing layer is a spot weld layer 5 that is evenly spaced vertically between the first inner flange 201 and the second inner flange 301.

[0056] The sealing strip 4 is a double-sided adhesive strip. Double-sided adhesive strips are easy to operate manually, do not require high operator skills, are easier to implement in automated production lines, effectively reduce labor intensity, and are also inexpensive.

[0057] This embodiment uses several connecting units spliced ​​and fixed to form a compartment panel. Each connecting unit includes a connecting plate 1 and a first connecting head 2 and a second connecting head 3 that match on both sides of the connecting plate 1. A pair of sealing strips 4 are set between the first connecting head 2 and the second connecting head 3. At the same time, the first connecting head 2 and the second connecting head 3 are fixed between the pair of sealing strips 4 by a fixing layer, which effectively isolates the moisture inside and outside the compartment and also avoids the fixing layer from being affected by the external environment, thus improving the connection stability. While effectively ensuring the connection strength, it improves the sealing effect at the connection. It can be used with materials such as ordinary carbon steel, high-strength steel, aluminum, and stainless steel, and greatly reduces production costs and consumables. It is especially suitable for industrial mass production and the construction of unmanned production lines.

[0058] Example 2:

[0059] like Figure 5 As shown, the structure of this embodiment is basically the same as that of embodiment 1, with the following differences:

[0060] In this embodiment, only a sealing strip 4 extending from the bottom end to the top end is provided between the first connector 2 and the second connector 3. The sealing strip 4 is provided on the side of the fixed layer facing the outside of the compartment, which isolates the water vapor outside the compartment and provides a certain degree of protection for the fixed layer.

[0061] Example 3:

[0062] like Figure 6 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that:

[0063] This embodiment does not have a pair of sealing strips 4. The sealing structure adopted in this embodiment is an external glue layer 6 set at the gap between adjacent connecting plates 1. The external glue layer 6 extends from the bottom end to the top end to seal the connection area between the first connector 2 and the second connector 3.

[0064] The connection area of ​​the first connector 2 and the second connector 3 is sealed by the external adhesive layer 6, which effectively isolates the environment inside and outside the compartment, and at the same time provides a certain degree of protection for the fixing layer.

[0065] Example 4:

[0066] like Figure 7 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that:

[0067] In addition to the pair of sealing strips 4 in the embodiment, this embodiment further provides an external glue layer 6 disposed at the gap between adjacent connecting plates 1. The external glue layer 6 extends from the bottom end to the top end to seal the connection area between the first connector 2 and the second connector 3.

[0068] The connection area of ​​the first connector 2 and the second connector 3 is sealed by the external adhesive layer 6, which further isolates the environment inside and outside the compartment, and at the same time provides a certain degree of protection for the fixing layer.
