[0039] Descriptions of directions in any embodiment herein, such as "up/down", "left/right", "top/bottom", etc., are all based on the direction of the drawing itself for convenience of description, and will not This limits the present invention.
[0040] In such figure 1 with figure 2 In the first embodiment shown according to the present invention, the composite structural panel 1 is mainly composed of three components: the panel 2 facing outwards during normal use, which is fixedly connected to the panel by adhesive or any other feasible means. The bottom plate 3, and the reinforcing member 4 provided at the peripheral portions of the panel 2 and the bottom plate 3.
[0041] The panel 2 has a main body portion 2c that is substantially on the same plane and a peripheral portion 2a formed by bending the main body portion 2c downward to surround the main body portion, and the panel 2 has an upper surface facing outward in normal use and The lower surface facing inward in normal use. The bottom plate 3 is formed with a substantially uniformly distributed integrally formed plurality of protrusions or protrusion arrays 3a, wherein the lower surface of the panel 2 is adhered and supported on the top surface of the plurality of protrusions 3a by thermal welding, and the bottom plate 3 The circumferential edge of the abuts against the inner surface of the peripheral portion 2a of the panel in the horizontal direction. Preferably, the adhesive is coated on the top surface of the protrusion 3a so as to form a point-like bond with the lower surface of the panel 2.
[0042] The panel 2 can be a blister plastic plate or formed by an injection molding process. The bottom plate 3 can be formed by the same molding process as the panel, but some are integrally formed by a blister process. Although truncated cone-shaped protrusions or protrusion arrays 3a are uniformly and staggeredly formed on the bottom plate 3 as seen in the figure, the shape, depth or arrangement of the protrusions 3a can be adjusted and changed according to actual requirements.
[0043] The reinforcing member 4 is preferably made of metal, more preferably of steel, but can also be made of hard plastic, as long as it can achieve the purpose of providing enhanced strength for the composite structural panel.
[0044] Although the composite structural panel as described above is formed of three components, the composite structural panel whose strength to be protected is significantly improved and the number of component parts is reduced is called "double-layer composite structural panel" in this application because The reinforcement 4 between the panel 2 and the bottom plate 3 is actually only connected to each other at the periphery of the composite structural panel.
[0045] figure 2 Yes figure 1 An enlarged view of part A in the middle, which specifically shows the specific structure of the reinforcement 4 and the connection mode with the panel 2 and the bottom plate 3. The reinforcing member 4 in this embodiment is a frame structure with a rectangular or square cross-section. The frame structure may be hollow, or the cross-sectional shape of the reinforcing member 4 is a closed frame. The peripheral portion 2a of the panel 2 is bent downward and continues to extend downward, and the outermost vertical edge of the reinforcing member 4 is attached to the downward peripheral portion 2a, and its bottom end slightly protrudes outward in the horizontal direction to form an integral The flange 4a, the free end 2b of the downwardly extending part of the panel is just supported on the flange 4a so that the end of the flange 4a is substantially flush with the outer surface of the extension.
[0046] More specifically, the peripheral portion 2a of the panel 2 formed by the downward bending of the main body portion 2c extends downward to form an extension in a direction substantially perpendicular to the main body portion 2c of the panel 2. The main body portion 2c is substantially parallel and abuts against the lower surface of the bottom plate 3, and the outermost vertical surface of the reinforcing member 4 abuts against the inner surface of the vertical extension of the peripheral portion 2a, and at the lower end of the vertical surface A flange 4a is formed protruding outward, and the free end 2b of the extension of the panel 2 is supported on the flange 4a.
[0047] although figure 2 The cross section of the reinforcing member 4 shown in the figure is rectangular or square, but it can be regarded as an enlarged scale in order to clearly see the position and configuration of the reinforcing member 4. The aspect ratio of the reinforcement 4 in the actual product can be larger or smaller according to actual design requirements. In addition, figure 2 The cross-section of the reinforcing member 4 shown in is a closed frame structure. However, in other embodiments, the reinforcing member 4 may be broken at one of the edges, presenting, for example, a back-to-back "double L-shaped" structure.
[0048] figure 2 The top of the reinforcing member 4 can be fixed and bonded to the bottom plate 3 with an adhesive, as described above, or can be clamped to the bottom surface of the bottom plate 3 by machining. . In order to more securely make the leftmost side of the reinforcement 4 adhere to and hold in place the inner surface of the downwardly extending peripheral portion 2a of the panel 2, the left side of the reinforcement 4 and the inner surface of the panel 2 can also be Apply adhesive etc., and fix the connection by hot-melt welding after it is in place.
[0049] figure 2 It also shows that the outermost part of the bottom plate 3 is a flat part without protrusions, and this part is slightly recessed upward in the direction of the panel 2, forming a recessed portion 3b with a flat bottom surface and a width greater than the width of the reinforcing member 4, thereby strengthening The top end of the member 4 can be placed in the recess 3b, so that the top surface of the reinforcing member 4 and the lower surface of the recess 3b of the bottom plate 3 are fixedly connected. Here, the fixed connection can also be achieved by applying an adhesive followed by thermal welding.
[0050] figure 2 It also clearly shows that a flange 4a is formed at the lower left part of the reinforcement 4, by means of which the reliable positioning and support of the reinforcement 4 relative to the panel 2 can be achieved.
[0051] Specifically, the reinforcement 4 has a bottom end, that is, figure 2 The lowermost surface as seen in, the lowermost surface is opposed to the top end of the reinforcing member 4 connected to the panel 2. After the assembly of the panel 2, the bottom plate 3 and the reinforcement 4 is completed, the lowermost surface of the reinforcement 4 will form the bottom end of the double-layer composite structure panel. The bottom end may be, for example, a complete and continuous reinforcement frame, such as metal Frame or rigid plastic frame. It is also conceivable that it may be an intermittent or segmented reinforced frame, such as a metal frame or a plastic frame.
[0052] The width of the reinforced frame will be much larger than the width of the lower edge of the panel 2, thereby not only enhancing the strength of the composite structural panel, but also supporting the composite structural panel. In addition, the thickness of the reinforcing member 4 may be 0.2, 0.4 or 1.0 times the thickness of the plastic panel 2.
[0053] image 3 It shows a second embodiment according to the present invention. Similar to the first embodiment, the composite structural panel according to this embodiment is formed of three parts, namely, the outward facing panel in normal use 2, through adhesives, etc. The bottom plate 3 fixedly connected with the panel 2 in any other feasible manner, and the reinforcement member 4 at least partially disposed between the panel 2 and the bottom plate 3.
[0054] In such image 3 In the second embodiment shown, the left and right ends of the panel 2 each have a reinforcing member 4 with an inverted L-shaped hollow frame structure, and the reinforcing member 4 on the left and the reinforcing member 4 on the right are arranged in mirror symmetry, and , A right-angled side of each of the two reinforcements 4 is parallel to the top plate 2 and close to the bottom surface of the top plate 2, and adhesives can be applied at the positions where they abut each other, and then further achieved by thermal welding The firm bond.
[0055] Figure 4 A third embodiment according to the present invention is shown, wherein the structure, relative position and connection mode of the components of the double-layer composite structure panel are the same as or similar to those described in the first and second embodiments, The main difference between them lies in the following two aspects:
[0056] First, a recess or clasp 5 is formed on the panel 2 or its outward surface. The recess or clasp will be located on the outermost surface of furniture assembled from composite structural panels, such as a cabinet formed on a cabinet. On the door, it is convenient for users to open and close the cabinet door, or to grasp the composite structure board itself. Preferably, the shape design of the clasp 5 conforms to ergonomics, so that the user can operate separately, thereby enhancing the user's experience of use.
[0057] Second, the shape of the reinforcement 4 appears as image 3 As shown in the "L" shape, the ratio of the vertical part and the horizontal part of the L-shaped structure can be adjusted according to actual needs, for example, the vertical part can be longer or shorter than the horizontal part. That is, in this embodiment, the reinforcing member 4 is a frame structure with an L-shaped cross section, and the bottom end of the outermost vertical side of the L-shape protrudes outward to form a flange 4a, and the peripheral portion 2a of the panel 2 faces The free end 2b extending downward will be stably supported on the flange 4a.
[0058] More specifically, the reinforcing member 4 is a substantially L-shaped hollow frame structure 4 with an upright cross-section. One vertical side of the L-shaped hollow frame structure is located near the innermost side of the protrusion 3a on the bottom plate 3 and perpendicular to the panel. 2. The lowermost end of the outer step-shaped surface of the L-shaped hollow frame structure protrudes outward to form a flange 4a, and the peripheral portion 2a of the panel 2 is continuously bent downwards in a direction substantially perpendicular to the main body portion 2c. And the shape of the stepped portion matches the shape of the stepped surface of the L-shaped frame structure. The free end 2b of the stepped extension of the panel 2 is stably supported on the flange 4a.
[0059] in Figure 4 In the third embodiment shown, the shape of the panel 2 at its edge, that is, the peripheral portion 2a, is different from that in the first and second embodiments. From Figure 4 It can be clearly seen that the shape of the peripheral portion 2a of the panel matches the shape of the reinforcement 4, that is, the peripheral portion 2a is attached to the L-shaped structure of the reinforcement 4 and also presents an L-shaped structure. Through this mutual cooperation in shape, the shape of the panel 2 is not only changed and more beautiful, but also the fixed combination of the panel 2 and the reinforcement 4 is further realized, thereby enhancing the overall strength of the composite structural panel. Of course, the panel 2 can also adopt the structure described in the first embodiment and the second embodiment, that is, bend only once.
[0060] Figure 5 with Image 6 Shows a fourth embodiment according to the present invention. Similar to the aforementioned first, second, and third embodiments, the composite structural panel according to the fourth embodiment is also composed of three parts, that is, it faces outwards during normal use. The panel 2, the bottom plate 3 fixedly connected with the panel by any other feasible means such as adhesive, and the reinforcement member 4 at least partially arranged between the panel 2 and the bottom plate 3.
[0061] From Figure 5 It can be seen that the reinforcing member 4 on the left side and the reinforcing member 4 on the right side can be connected with the panel 2 and the bottom plate 3 by using two kinds of reinforcing members with different cross-sectional shapes according to actual conditions. Correspondingly, the shape of the panel 2 can also be adaptively matched as the configuration of the reinforcement 4 changes. This facilitates the realization of different ways of assembly according to different needs.
[0062] The structure, relative position and connection manner of the components of the double-layer composite structure panel according to the fourth embodiment, the width and thickness of the reinforcing member 4, etc., are the same as those described in the foregoing first embodiment.
[0063] One of the obvious differences between the fourth embodiment and the first embodiment lies in whether the panel 2 and the bottom plate 3 are in close contact or a certain distance. in figure 2 In the first embodiment shown, it can be seen that above the reinforcing member 4, there is a relatively large gap between the main body portion 2c of the panel 2 and the bottom plate 3, and one or more transverse or reinforcing elements can be further provided therebetween. The longitudinally parallel reinforcing ribs of the member 4 can further enhance the strength of the composite structural panel. In the second to fourth embodiments, it can be seen that the main body portion 2c of the panel 2 is closely attached to the outer periphery of the bottom plate 3, that is, at the position where the bottom plate 3 and the reinforcement member 4 are connected, the panel, the bottom plate and the reinforcement member There is no gap between.
[0064] In addition, Picture 10 A fifth embodiment according to the present invention is shown. As shown in the figure, the cross-section of the reinforcing member 4 presents a back-to-back "double L-shape" structure, and the double L-shapes share the same vertical side 5 along with The main body portion 2 extends in a substantially vertical direction to abut against the lower surface of the panel 2, and the vertical side extends against the inner surface of the peripheral portion 2a and is located inside the peripheral portion, and the L-shaped structure on the outside extends laterally outward The bottom edge of the peripheral portion 2a is bent upward around the lowermost end of the extension portion, so as to surround the bottom edge of the peripheral portion 2a.
[0065] As a preferred embodiment, the ends of the vertical sides of the back-to-back double L-shaped structure in the fifth embodiment are horizontally bent inward in a direction substantially parallel to the main body portion 2c of the panel 2 to tightly press on On the edge of the bottom plate 3.
[0066] The fixed connection between the two is further achieved by making the laterally outwardly extending bottom edge of the outer L-shaped structure tightly wrap at least a part of the bottom edge of the peripheral portion 2a of the panel 2. This can be done by any known process or by means of any known tool. The wrapped area occupies one-fifth, one-quarter, one-third, etc. of the peripheral portion 2a of the panel 2 in the vertical direction; in the lateral direction, that is, along the circumferential direction of the panel 2, it can be wrapped The entire edge of the peripheral portion 2a of the panel or intermittently surrounds the edge of the peripheral portion 2a of the panel.
[0067] In any of the above embodiments, the outwardly extending end of the flange 4a may be substantially flush with the outer surface of the extending portion of the circumferential portion 2a. Preferably, the formed flange 4a will be slightly offset outward relative to the extension of the circumferential portion 2a, so that the obtained composite structural panel has a relatively smooth outer edge, thereby avoiding scratches or scratches to the user Broken clothes etc.
[0068] Similarly, in the fifth embodiment where the cross-section of the reinforcing member 4 is a double L-shaped structure, the outer L-shaped lateral side forming the lower edge of the surrounding peripheral portion 2a is also preferably smooth or has rounded corners to Avoid scratching the user or scratching clothing.
[0069] Figure 7 The top surface or outermost surface 1a of the panel 2 of the double-layer composite structure panel is shown, which can be a flat regular surface and used as, for example, Figure 8 , Picture 9 The top surface 1a of the cabinet shown. Preferably, the top surface 1a of the panel 2 made of plastic can be attached to a veneer that imitates the texture of natural wood or stone, so that the composite structural board has an appearance that imitates natural materials. The surface of the composite structure board can also have grooves formed into various shapes by blister to make it look more natural and beautiful. In this case, the complementary surface of the reinforcing member 4 may be molded with corresponding grooves to support the blister plastic panel and/or the bottom plate, while increasing the strength of the composite structural panel. Among them, the reinforcing member 4 can be formed by stretching and crimping or bending.
[0070] Figure 8 , Picture 9 A cabinet assembled from composite structural panels according to any embodiment of the present application is shown. The composite structural panel 1 can be used as furniture, such as the top panel, bottom panel, side panel, etc. of a cabinet.
[0071] In various embodiments, the plastic panel and/or the bottom plate may be a blister or injection molded plastic plate, and the reinforcement may be a molded or tensile reinforcement.
[0072] The features described in one embodiment in this application can be applied in other embodiments. The composite structural panels described above for cabinets can of course also be used for partitions, drawers and other furniture parts of tables, shelves, backrests, bookshelves or cabinets.
[0073] As such, various embodiments have been shown and described. Of course, various changes and substitutions can be made without departing from the spirit and scope of the present invention. Therefore, the present invention is not subject to other restrictions except for the appended claims and their equivalent scope.
