Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] see figure 1 , the present invention provides a combination structure of a plastic 20 and a hard substrate 10, the hard substrate 10 is provided with a combination hole 30 for it to be combined with the plastic 20, wherein the hard substrate 10 is a metal substrate, Of course, the metal composite material base material can also be a non-metal composite material; and the plastic 20 is a high molecular polymer. The joint hole 30 includes a top end 31, a bottom end 32 and a constriction end 33 between the top end 31 and the bottom end 32, the top end 31 and the constriction end 33 are connecte...

Abstract

The invention provides a plastic cement and hard base material combining structure. A combining hole used for being combined with plastic cement is formed in a hard base material, the combining hole comprises a top end, a bottom end and a constriction end, the top end and the constriction end are connected through a first transition section, the bottom end and the constriction end are connected through a second transition section, the cross section width of the top end is D1, the cross section width of the bottom end is D2, the cross section width of the constriction end is d, and in addition, d is smaller than min{D1 and D2}. The combining hole is formed in the hard base material, in addition, the cross section width of the top end and the cross section width of the bottom end of the combining hole are respectively greater than the cross section width of the constriction end, the plastic cement part after the combining hole solidification is equivalent to a buckling element with two large ends and small middle so that the plastic cement part can be tightly buckled on the hard base material, and the risk that a combing part of the hard base material and the plastic cement part generates layered cracking is reduced. The invention also provides an LED (light emitting diode) lamp support frame and a plastic cement and hard base material combining method.

Description

technical field [0001] The invention relates to the technical field of combining plastics with hard substrates, in particular to a combination structure and method for combining plastics and hard substrates, and an LED lamp bracket adopting the combination structure. Background technique [0002] At present, the combination structure of plastic and hard substrate is generally to first increase the roughness of the surface of the hard substrate, then make the molten plastic contact the hard substrate, and then cool and solidify to finally bond the plastic and the hard substrate . However, with this combination structure, if the plastic encounters a large impact, the joint between the hard substrate and the plastic is prone to delamination and cracking. [0003] Therefore, it is necessary to provide a technical means to solve the above defects. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, and provide a...
