[0048] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0049] See also Figure 1 An embodiment of the present application provides a metal composite part 100 , and the metal composite part 100 includes a metal substrate 10 and a bonding body 20 connected to the metal substrate 10 .
[0050] To facilitate understanding and explanation of the embodiments of the present application, a three-dimensional coordinate system is established in some of the drawings, where the X-axis direction is the first direction, the Y-axis direction is the second direction, and the Z-axis direction is the third direction, and the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.
[0051] Please refer to Figure 1 and Figure 2 The metal substrate 10 is generally plate-shaped. The metal substrate 10 has a bonding surface 11 facing the bonding body 20. A recessed portion 12 is provided on the bonding surface 11 in a direction away from the bonding body 20. The recessed portion 12 includes two recessed structures 121. The two recessed structures 121 are arranged at intervals along the extension direction of the bonding surface 11. Each recessed structure 121 includes two recessed grooves 122 and two filling grooves 123. The recessed groove 122 includes a bottom surface 1221, a first inclined surface 1222, a second inclined surface 1223 and a vertical surface 1224. The extension direction of the bottom surface 1221 is inclined to the third direction. The first inclined surface 1222, the second inclined surface 1223 and the vertical surface 1224 are sequentially arranged around the circumference of the bottom surface 1221. The extension directions of the first inclined surface 1222 and the second inclined surface 1223 are both inclined to the third direction. The extension direction of the vertical surface 1224 is perpendicular to the third direction. Each filling groove 123 is opened in the groove wall of the corresponding recessed groove 122 close to another recessed groove 122, that is, the filling groove 123 is opened in the corresponding vertical surface 1224, and the opening direction of each recessed groove 122 intersects with the opening direction of the corresponding filling groove 123, that is, the X-axis direction intersects with the Z-axis direction. The combination 20 includes an adapting portion 21 and two combining portions 22, the adapting portion 21 is roughly plate-shaped, the adapting portion 21 is adapted to the combining surface 11 and is attached to the combining surface 11, the two combining portions 22 are respectively arranged in a one-to-one correspondence with the two recessed structures 121, and each combining portion 22 is filled into the corresponding recessed groove 122 and the filling groove 123.
[0052] In the above-mentioned metal composite 100, by setting the specific structure of the recessed portion 12 opened on the bonding surface 11 of the metal substrate 10, the two bonding portions 22 of the bonding body 20 can be filled into the two recessed grooves 122 and the two filling grooves 123 respectively, and the adapting portion 21 of the bonding body 20 is fitted with the bonding surface 11, so that a mutually locking structure is formed between the bonding body 20 and the metal substrate 10, thereby avoiding the occurrence of processing marks on the surface of the metal composite 100 formed by the combination of the metal substrate 10 and the bonding body 20, thereby improving the metal composite 100. 00 processing quality, and because the two filling grooves 123 are opened on the groove wall of the corresponding recessed groove 122, the combination 20 and the metal substrate 10 form a bonding force in the vertical direction of the direction in which the metal substrate 10 points to the combination 20, avoiding the metal substrate 10 and the combination 20 from loosening from each other, which is conducive to the stable combination of the metal substrate 10 and the combination 20, and there is no need to use rivets or press the metal substrate 10 and the combination 20 to a preset structure. It is suitable for metal substrates 10 and combinations 20 with different structures and shapes, and expands the scope of application.
[0053] It can be understood that, by means of the inclined bottom surface 1221, the first inclined surface 1222 and the second inclined surface 1223, the metal substrate 10 can provide support forces for the combination 20 filled into the metal substrate 10 in different directions, thereby improving the bonding force between the metal substrate 10 and the combination 20. In addition, by providing the filling groove 123 on the vertical surface 1224, it is convenient for the external processing part to provide the filling groove 123 on the groove wall of the recessed groove 122, thereby improving the convenience of forming the recessed structure 121.
[0054] The material of the metal substrate 10 is metal, such as titanium, and the material of the combination 20 can be metal, such as aluminum, or plastic. It can be understood that when the material of the combination 20 is metal, the combination 20 can be pressed by the external pressing member to fill the combination part 22 of the combination 20 into the recessed groove 122 and the filling groove 123. When the material of the combination 20 is plastic, the combination 20 can receive molten plastic under the action of the external injection mold to fill the combination part 22 of the combination 20 into the recessed groove 122 and the filling groove 123.
[0055] See also Figure 3 The metal substrate 10 has a plurality of recessed portions 12 on the bonding surface 11, and the plurality of recessed portions 12 are arranged in an array along the first direction and the second direction. In this way, the plurality of recessed portions 12 arranged in an array can provide a more uniform stress distribution, thereby improving the stability of the overall structure of the metal composite 100, and the array arrangement facilitates the external processing parts to open a plurality of recessed portions 12 on the bonding surface 11 of the metal substrate 10, thereby improving the manufacturing efficiency.
[0056] See also Figure 5 and Figure 6 The bottom surface 1221 , the first inclined surface 1222 and the second inclined surface 1223 constitute a conical structure 1225 , and the end of the conical structure 1225 away from the bonding surface 11 is a tip.
[0057] In this way, by setting the bottom surface 1221, the first inclined surface 1222 and the second inclined surface 1223 to form a conical structure 1225, the recessed groove 122 helps to guide the combination 20 to be filled more deeply into the metal substrate 10, thereby enhancing the connection tightness between the metal substrate 10 and the combination 20, and also facilitates the external processing parts to form the recessed groove 122 on the bonding surface 11 of the metal substrate 10.
[0058] See also Figure 4 and Figure 5 The inclination angles of the bottom surface 1221, the first inclined surface 1222 and the second inclined surface 1223 relative to the bonding surface 11 are all in the range of 110°-130°, that is, Figure 5 The first angle A shown is an obtuse angle. When the inclination angles of the bottom surface 1221, the first inclined surface 1222 and the second inclined surface 1223 are greater than 130°, the contact area between the combination 20 and the metal substrate 10 is reduced, thereby reducing the bonding strength between the metal substrate 10 and the combination 20, and the combination 20 is difficult to be effectively filled into the recessed groove 122, thereby affecting the bonding effect of the metal substrate 10 and the combination 20. In addition, it may also cause stress to concentrate at the contact point between the combination 20 and the metal substrate 10, increasing the risk of material fatigue and fracture. When the inclination angles of the bottom surface 1221, the first inclined surface 1222 and the second inclined surface 1223 are less than 110°, the filling capacity of the combination 20 is limited, thereby resulting in insufficient bonding force between the combination 20 and the metal substrate 10, thereby making the metal substrate 10 and the combination 20 easy to loosen from each other. In this way, by setting the inclination angle range of the bottom surface 1221, the first inclined surface 1222 and the second inclined surface 1223 to 110°-130°, sufficient contact area can be provided for the metal substrate 10 and the combination 20, which helps to enhance the bonding force between the combination 20 and the metal substrate 10, and helps to smoothly fill the combination 20 into the recessed groove 122 and the filling groove 123, thereby ensuring that the combination 20 is evenly distributed in the recessed groove 122 and the filling groove 123, thereby improving the bonding effect between the metal substrate 10 and the combination 20.
[0059] See also Figure 5 and Figure 6The cross section of the filling groove 123 in the vertical direction along the direction from the metal substrate 10 to the bonding body 20 is a right triangle, and the cross section includes a first straight side 1231, a second straight side 1232 and a hypotenuse 1233. The first straight side 1231, the second straight side 1232 and the hypotenuse 1233 are connected in sequence and surrounded to form a right triangle. The first straight side 1231 is located at the bottom of the filling groove 123 away from the bonding surface 11, and the second straight side 1232 is located at the groove wall of the recessed groove 122.
[0060] In this way, by setting the specific structure of the above-mentioned filling groove 123, the filling groove 123 can utilize the structural characteristics of a right-angled triangle, thereby improving the bearing capacity of the filling groove 123, facilitating precise control of the size of the filling groove 123, and ensuring the filling uniformity and bonding effect of the combination 20. At the same time, the hypotenuse 1233 of the cross section of the filling groove 123 helps to disperse stress and reduce local stress concentration, thereby enhancing the durability of the metal composite part 100.
[0061] Please continue reading Figure 5 , the angle between the second straight edge 1232 and the oblique edge 1233 is in the range of 25°-35°, that is, Figure 5 The second angle B shown is an acute angle. When the angle between the second straight edge 1232 and the hypotenuse 1233 is greater than 35°, it is difficult for the combination 20 to be filled into the filling groove 123 with a right triangle cross section, thereby affecting the bonding effect between the metal substrate 10 and the combination 20. When the angle between the second straight edge 1232 and the hypotenuse 1233 is less than 25°, the stability of the filling groove 123 is deteriorated, affecting the overall structural stability of the metal composite 100, and increasing the manufacturing complexity of the filling groove 123. In this way, by setting the angle between the second straight edge 1232 and the hypotenuse 1233 to be in the range of 25°-35°, it is helpful to fill the combination 20 into the filling groove 123, ensure the bonding effect between the metal substrate 10 and the combination 20, and facilitate the metal substrate 10 to be processed to form the filling groove 123.
[0062] The length range of the first straight side 1231 is 0.04mm-0.06mm, and the length range of the second straight side 1232 is 0.09mm-0.11mm. When the length of the first straight side 1231 and the second straight side 1232 is less than the above-mentioned length range, the contact area between the combination 20 and the metal substrate 10 is reduced, resulting in insufficient bonding strength. When the length of the first straight side 1231 and the second straight side 1232 is greater than the above-mentioned length range, a larger portion of the combination 20 needs to be filled into the filling groove 123, resulting in difficulty in filling. In addition, the limited space of the recessed structure 121 makes it difficult for the external processing parts to form the filling groove 123 with a longer length of the first straight side 1231 and the second straight side 1232 on the metal substrate 10. In this way, by setting the length of the first straight edge 1231 and the second straight edge 1232 to conform to the above-mentioned length range, a sufficiently large contact area can be provided between the combination 20 and the metal substrate 10, which helps to enhance the bonding force between the combination 20 and the metal substrate 10 and facilitates the filling operation of the combination 20 and the processing and forming of the filling groove 123.
[0063] The spacing between the bonding surface 11 and the first straight edge 1231 ranges from 0.04 mm to 0.06 mm. When the spacing between the bonding surface 11 and the first straight edge 1231 is less than 0.04 mm, the spacing between the filling groove 123 and the bonding surface 11 is too small, so that the depth of the combination 20 filled into the recessed structure 121 is insufficient, thereby limiting the filling depth of the combination 20, which weakens the bonding force between the combination 20 and the metal substrate 10 and affects the overall stability and strength of the metal composite 100. When the spacing between the bonding surface 11 and the first straight edge 1231 is greater than 0.06 mm, more combinations 20 will be required to fill the recessed groove 122 and the filling groove 123, which not only causes material waste, but also may increase production costs. In this way, by keeping the spacing between the bonding surface 11 and the first straight edge 1231 within the range of 0.04 mm to 0.06 mm, the bonding force between the metal substrate 10 and the combination 20 can be improved, material waste can be avoided, and production costs can be reduced.
[0064] In another embodiment, the metal substrate 10 is provided with a plurality of recessed portions 12 on the bonding surface 11, and the plurality of recessed portions 12 are arranged in a staggered manner along the first direction and the second direction. In this way, the plurality of recessed portions 12 arranged in a staggered manner can adapt to the shapes and structures of more complex metal substrates 10 and bonding bodies 20, providing higher design flexibility, thereby increasing the application range of the metal composite 100, and also helping to disperse stress, reduce local stress concentration, and improve the durability of the metal substrate 10.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
