Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of profiles, and in particular to a novel composite aluminum profile. Background Technology
[0002] Composite aluminum profiles are a new type of material that combines the excellent properties of aluminum alloys with the performance of polymer thermal insulation materials or other reinforcing materials. Through this combination, a thermal insulation interlayer or reinforcing layer is formed in the center of the aluminum alloy profile, thereby achieving properties such as thermal insulation, high strength, and lightweight.
[0003] In related technologies, the aluminum alloy and additive materials of composite aluminum profiles are bonded and fixed together by adhesive.
[0004] However, the bonding strength between the aluminum alloy and the reinforcing material in existing composite aluminum profiles relies solely on the adhesive force of the glue, resulting in poor bonding strength between the aluminum alloy and the reinforcing material, which in turn leads to a short service life for composite aluminum profiles. Utility Model Content
[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a novel composite aluminum profile that can improve the poor bonding strength between the aluminum alloy and the reinforcing material, thereby increasing its service life.
[0006] A novel composite aluminum profile according to an embodiment of the present utility model includes:
[0007] core material;
[0008] Aluminum alloy profile;
[0009] A polyurethane structural adhesive is disposed between the core material and the aluminum alloy outer profile to bond the core material and the aluminum alloy outer profile.
[0010] The snap-fit assembly includes a first snap-fit portion and a second snap-fit portion. The first snap-fit portion is integrally formed on one of the core material and the aluminum alloy outer profile, and the second snap-fit portion is integrally formed on the other of the core material and the aluminum alloy outer profile. The first snap-fit portion and the second snap-fit portion are engaged to prevent detachment.
[0011] A novel composite aluminum profile according to an embodiment of the present utility model has at least the following beneficial effects:
[0012] 1. This utility model uses polyurethane structural adhesive between the core material and the aluminum alloy profile. The polyurethane structural adhesive is used to bond the core material and the aluminum alloy profile. It is understood that the polyurethane structural adhesive has extremely strong adhesion properties, which can enhance the adhesion between the core material and the aluminum alloy profile, and is conducive to improving the fixing strength between the core material and the aluminum alloy profile. At the same time, after the polyurethane structural adhesive solidifies, it can withstand large dynamic and static loads and maintain stable performance over a long period of time. Thus, the new composite profile has good load-bearing capacity and structural stability.
[0013] 2. This utility model, by setting a snap-fit assembly, includes a first snap-fit part and a second snap-fit part. The first snap-fit part is integrally formed in one of the core material and the aluminum alloy outer profile, and the second snap-fit part is integrally formed in the other of the core material and the aluminum alloy outer profile. The first snap-fit part and the second snap-fit part are snapped together to prevent detachment. It can be understood that by using the snap-fit part to prevent detachment, the core material and the aluminum alloy outer profile can be fixed together by the adhesion force of the polyurethane structural adhesive and the snap-fit force of the mechanical structure between the first snap-fit part and the second snap-fit part, which effectively improves the fixing strength between the aluminum alloy and the core material and increases the service life of the new composite profile.
[0014] According to some embodiments of the present invention, the first latching part includes two first latching arms, and the two first latching arms have a first protrusion on the side that is close to each other. The second latching part is disposed between the two first latching arms and latches with the two first protrusions.
[0015] The advantages of this invention are: by including two first locking arms in the first locking part, with a first protrusion on the side of the two first locking arms that are close to each other, and the second locking part being disposed between the two first locking arms and engaging with the two first protrusions, the two first locking arms can limit the two sides of the second locking part. At the same time, the first locking part engages with the second locking part through the two first protrusions, so that there are two locking positions between the first locking part and the second locking part, thereby making the engagement between the first locking part and the second locking part more secure.
[0016] According to some embodiments of the present invention, a first inclined surface is provided on one side of the first protrusion, and the first inclined surface is used to guide the second snap-fit portion into the space between the two first snap-fit arms.
[0017] The advantage of this invention is that by providing a first inclined surface on one side of the first protrusion, the first inclined surface is used to guide the second snap-fit part into the space between the two first snap-fit arms. Thus, when the second snap-fit part is snapped into the space between the two first snap-fit arms, the first inclined surface can guide the second snap-fit part when it contacts the first protrusion, so that the second snap-fit part can pass smoothly through the first protrusion, avoiding the first protrusion from obstructing the passage of the second snap-fit part. In this way, it is beneficial to snap-fit the first snap-fit part and the second snap-fit part.
[0018] According to some embodiments of the present invention, the second latching portion includes two second latching arms, and the two second latching arms have a second protrusion on the side that is far apart from each other, and the two second protrusions are respectively latched with the two first protrusions.
[0019] The advantages of this invention are: by including two second locking arms in the second locking part, and having a second protrusion on the side of the two second locking arms that are far apart from each other, and having the two second protrusions respectively locking with the two first protrusions, more space is provided between the two second locking arms to accommodate the polyurethane structural adhesive, thereby enhancing the bonding effect of the polyurethane structural adhesive to the core material and the aluminum alloy outer profile, and improving the fixing strength between the core material and the aluminum alloy outer profile.
[0020] According to some embodiments of the present invention, a second inclined surface is provided on one side of the second protrusion, and the second inclined surface is used to guide and engage the first protrusion.
[0021] The advantage of this invention is that by providing a second inclined surface on one side of the second protrusion, the second inclined surface is used to guide and engage the first protrusion. Thus, when the second engaging part is engaged between the two first engaging arms, the second inclined surface can guide the first protrusion when it contacts the second protrusion, allowing the first protrusion to pass smoothly through the second protrusion and preventing the second protrusion from obstructing the passage of the first protrusion. This facilitates the engaging and installation of the first engaging part and the second engaging part.
[0022] According to some embodiments of the present invention, the root portion of the two second card arms on the side close to each other has a first recess.
[0023] The advantage of this invention is that by providing a first recess at the root of the two second locking arms on the side that are close to each other, when the first protrusion and the second protrusion are pressed against each other, the second locking arm can be bent and deformed along the first recess, so that the second protrusion can pass through the first protrusion. After the second protrusion passes through the second protrusion, the second locking arm restores its deformation, thereby making the first protrusion and the second protrusion engage with each other.
[0024] According to some embodiments of the present invention, the thickness of the second card arm is less than the thickness of the first card arm.
[0025] The advantage of this invention is that by making the thickness of the second clamping arm less than that of the first clamping arm, the second clamping arm can be bent and deformed to avoid the first protrusion when the first protrusion and the second protrusion are pressed against each other.
[0026] According to some embodiments of the present invention, two first clamping arms are formed on the core material, and two second clamping arms are formed on the aluminum alloy profile. A first protruding edge is provided on one side of the core material, and the first protruding edge is located between the two second clamping arms.
[0027] The advantages are: the present invention uses two first clamping arms formed on the core material and two second clamping arms formed on the aluminum alloy outer profile. A first protruding edge is provided on one side of the core material, and the first protruding edge is located between the two second clamping arms. This increases the contact area between the polyurethane structural adhesive and the core material and the aluminum alloy outer profile, thereby enhancing the adhesion effect of the polyurethane structural adhesive to the core material and the aluminum alloy outer profile.
[0028] According to some embodiments of the present invention, two first locking arms are formed on the aluminum alloy outer profile, one side of the core material has a second protruding edge, the second protruding edge forms a second locking portion, the second protruding edge is embedded between the two first locking arms, and the two sides of the second protruding edge have first grooves, the two first grooves respectively engage with the two first protruding portions.
[0029] The advantages of this invention are: by forming two first locking arms on an aluminum alloy profile, and having a second protruding edge on one side of the core material, the second protruding edge forms a second locking portion, which is embedded between the two first locking arms. The two sides of the second protruding edge have first grooves, and the two first grooves respectively engage with the two first protrusions. This increases the contact area between the polyurethane structural adhesive and the core material, thereby enhancing the adhesion effect of the polyurethane structural adhesive to the core material.
[0030] According to some embodiments of the present invention, the first groove is configured as an arc-shaped groove.
[0031] The advantage is that by setting the first groove as an arc-shaped groove, this utility model facilitates the entry of the first protrusion into the arc-shaped groove.
[0032] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-3 This invention describes a novel composite aluminum profile according to an embodiment of the present invention.
[0043] The present invention aims to provide an embodiment of a novel composite aluminum profile.
[0044] Reference Figure 1 In this embodiment, a novel composite aluminum profile mainly includes a core material 100, an aluminum alloy outer profile 110, a polyurethane structural adhesive 120, and a snap-fit assembly.
[0045] The polyurethane structural adhesive 120 is disposed between the core material 100 and the aluminum alloy outer profile 110, and is used to bond the core material 100 and the aluminum alloy outer profile 110.
[0046] Understandably, polyurethane structural adhesive 120 has extremely strong adhesion properties, which can enhance the adhesion between the core material 100 and the aluminum alloy outer profile 110, thereby improving the fixing strength between the core material 100 and the aluminum alloy outer profile 110. At the same time, after the polyurethane structural adhesive 120 solidifies, it can withstand large dynamic and static loads and maintain stable performance over a long period of time. As a result, the new composite profile has good load-bearing capacity and structural stability.
[0047] The snap-fit assembly includes a first snap-fit part and a second snap-fit part. The first snap-fit part is integrally formed on one of the core material 100 and the aluminum alloy outer profile 110, and the second snap-fit part is integrally formed on the other of the core material 100 and the aluminum alloy outer profile 110. The first snap-fit part and the second snap-fit part are engaged to prevent detachment.
[0048] It is understandable that by using the first and second snap-fit parts to prevent detachment, the core material 100 and the aluminum alloy outer profile 110 can be fixed together by the adhesion of the polyurethane structural adhesive 120 and the snap-fit force of the mechanical structure between the first and second snap-fit parts, which effectively improves the fixing strength between the aluminum alloy and the core material 100 and increases the service life of the new composite profile.
[0049] Specifically, the polyurethane structural adhesive 120 is disposed between the first snap-fit portion and the second snap-fit portion.
[0050] In some specific embodiments, the first latching portion includes two first latching arms 130, and the two first latching arms 130 have a first protrusion 140 on the side close to each other. The second latching portion is disposed between the two first latching arms 130 and latches with the two first protrusions 140, thereby enabling the two first latching arms 130 to limit the two sides of the second latching portion. At the same time, the first latching portion latches with the second latching portion through the two first protrusions 140, so that there are two latching positions between the first latching portion and the second latching portion, thereby making the latching between the first latching portion and the second latching portion more secure.
[0051] Furthermore, a first inclined surface 150 is provided on one side of the first protrusion 140. The first inclined surface 150 is used to guide the second engaging part into the space between the two first engaging arms 130. Thus, when the second engaging part is engaged between the two first engaging arms 130, the first inclined surface 150 can guide the second engaging part when it contacts the first protrusion 140, so that the second engaging part can pass smoothly through the first protrusion 140, avoiding the first protrusion 140 from obstructing the passage of the second engaging part. This facilitates the engaging and installation of the first engaging part and the second engaging part.
[0052] In some specific embodiments, the second snap-fit portion includes two second snap-fit arms 160. The two second snap-fit arms 160 have a second protrusion 170 on the side that is far apart from each other. The two second protrusions 170 are snap-fitted with the two first protrusions 140 respectively. This allows more space between the two second snap-fit arms 160 to accommodate the polyurethane structural adhesive 120, which in turn helps to strengthen the adhesion of the polyurethane structural adhesive 120 to the core material 100 and the aluminum alloy outer profile 110, and improves the fixing strength between the core material 100 and the aluminum alloy outer profile 110.
[0053] Furthermore, a second inclined surface 180 is provided on one side of the second protrusion 170. The second inclined surface 180 is used to guide and engage the first protrusion 140. Thus, when the second engaging part is engaged between the two first engaging arms 130, the second inclined surface 180 can guide the first protrusion 140 when it contacts the second protrusion 170, so that the first protrusion 140 can pass smoothly through the second protrusion 170, avoiding the second protrusion 170 from obstructing the passage of the first protrusion 140. This facilitates the engaging and installation of the first engaging part and the second engaging part.
[0054] In some specific embodiments, the root of the two second locking arms 160 on the side that is close to each other has a first recess 190, so that when the first protrusion 140 and the second protrusion 170 are pressed against each other, the second locking arm 160 can be bent and deformed along the first recess 190, so that the second protrusion 170 can pass through the first protrusion 140. After the second protrusion 170 passes through the second protrusion 170, the second locking arm 160 restores its deformation, thereby making the first protrusion 140 and the second protrusion 170 engage with each other.
[0055] In some specific embodiments, the thickness of the second clamping arm 160 is less than the thickness of the first clamping arm 130, so that when the first protrusion 140 and the second protrusion 170 are pressed against each other, the second clamping arm 160 can be bent and deformed to avoid the first protrusion 140.
[0056] Reference Figure 2 In some specific embodiments, two first clamping arms 130 are formed on the core material 100, and two second clamping arms 160 are formed on the aluminum alloy outer profile 110. A first protruding edge 200 is provided on one side of the core material 100, and the first protruding edge 200 is located between the two second clamping arms 160. This increases the contact area between the polyurethane structural adhesive 120 and the core material 100 and the aluminum alloy outer profile 110, thereby enhancing the bonding effect of the polyurethane structural adhesive 120 on the core material 100 and the aluminum alloy outer profile 110.
[0057] Reference Figure 3 In other embodiments, two first locking arms 130 are formed on the aluminum alloy outer profile 110, and the core material 100 has a second protruding edge 210 on one side, which forms a second locking portion. The second protruding edge 210 is embedded between the two first locking arms 130, and the two sides of the second protruding edge 210 have first grooves 220. The two first grooves 220 are respectively engaged with the two first protrusions 140, thereby increasing the contact area between the polyurethane structural adhesive 120 and the core material 100, which in turn helps to enhance the bonding effect of the polyurethane structural adhesive 120 to the core material 100.
[0058] Furthermore, the first groove 220 is configured as an arc-shaped groove, which facilitates the entry of the first protrusion 140 into the arc-shaped groove.
[0059] In some specific embodiments, a second groove is provided on the side wall of the first protrusion 200. The second groove is used to accommodate the polyurethane structural adhesive 120. Thus, when the polyurethane structural adhesive 120 is cured in the second groove, it can form a structure that snaps into the second groove, thereby enhancing the fixing strength between the polyurethane structural adhesive 120 and the core material 100.
[0060] Furthermore, a second groove is provided on both sides of the first protrusion 200, thereby further strengthening the fixing strength between the polyurethane structural adhesive 120 and the core material 100.
