In addition, the terms "upper", "lower", "left", "right", "side" and "middle" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

Fig. 1 shows a plastic structure for assembly with an aluminum alloy of the present embodiment. Specifically, this structure includes working of plastics 100, and the through-hole is seted up at working of plastics 100's corner, and this through-hole is locating hole 150, puts into aluminum alloy frame 200 with working of plastics 100 whole, and 4 locating holes 150 on the working of plastics 100 aim at 4 bosss on aluminum alloy frame 200 to realize preliminary location.

Wherein, the side of the plastic body 100 is provided with a bearing beam 110, as shown in fig. 4, a notch 111 is formed on the bearing beam 110 to avoid the limiting table 210 on the aluminum alloy frame 200. Through the arrangement of the notch 111, when the plastic part body 100 is assembled with the aluminum alloy frame 200, the plastic part body 100 is prevented from being irreversibly deformed due to excessive extrusion, and the rejection rate of products is low in the assembling process.

In addition, the plastic part body 100 includes a support beam 120 located at the bottom of the gap 111, and the support beam 120 is used to provide a supporting force for the plastic part body 100 at the gap 111, which contributes to stronger stability of the plastic part body 100 during use. The support beam 120 of the present embodiment extends in the height direction of the load-bearing beam 110 to form the elastic buckle 130, the elastic buckle 130 includes a connection plate 131 having a bent cross section, and the connection plate 131 deforms to avoid the limit table 210 on the aluminum alloy frame 200.

In order to facilitate the assembly of the plastic body 100 and the aluminum alloy frame 200, as shown in fig. 2, a gap is left between each of the left and right side portions of the elastic buckle 130 and the adjacent bearing beam 110, and the position of the elastic buckle 130 corresponds to the position of the limiting table 210 on the aluminum alloy frame 200. When downward pressure is applied to the plastic body 100, due to the arrangement of the gap, the connecting plate 131 of the elastic buckle 130 is more easily deformed, and an avoiding space is formed at the notch 111 instantly so as to allow the limiting table 210 on the aluminum alloy frame 200 to pass through. When the position limiting table 210 slides to the upper side of the elastic buckle 130, that is, after the plastic body 100 is completely pressed into the aluminum alloy frame 200, the pressure applied to the plastic body 100 is removed, and the connecting plate 131 of the elastic buckle 130 is restored by the resilience of itself, thereby completing the assembly.

Preferably, the number of the elastic buckles 130 is arranged in a group to further improve the tightness of the assembly between the plastic body 100 and the aluminum alloy frame 200. Specifically, the set of elastic buckles 130 of the present embodiment are symmetrically disposed on the side of the plastic body 100.

In order to avoid the influence of too thick material on the resilience of the elastic buckle 130 during use, a transition region is provided between the support beam 120 and the elastic buckle 130, and the transition region may be in the form of a step 121. In this embodiment, the step 121 is formed by extending the top surface of the support beam 120 upward, and the top of the step 121 is connected to the connection plate 131 of the elastic buckle 130. It is noted that the width of the step 121 is smaller than that of the support beam 120, and the width of the step 121 is larger than that of the connection plate 131, so as to ensure flexible resilience of the connection plate 131 during the assembling process.

Further, the end of the elastic buckle 130 away from the support beam 120 is provided with a clip 140, and the top end of the clip 140 abuts against the bottom end of the position limiting table 210 on the inner wall of the aluminum alloy frame 200. Specifically, as shown in fig. 3 and 4, the top end of the clip 140 is provided with a first end surface 141, and the bottom end of the limiting platform 210 is provided with a second end surface 211, when the plastic body 100 and the aluminum alloy frame 200 of the present embodiment are in an assembled state, the mutual limiting between the clip 140 and the limiting platform 210 is realized by the close fitting of the first end surface 141 and the second end surface 211.

The notch is arranged at the clamping position of the plastic body 100 and the aluminum alloy frame 200, and the elastic buckle 130 is arranged at the notch, so that the plastic body 100 is not required to be pressed down by the assembly mode of the buckle type, the assembly operation is more labor-saving, and the workload in the assembly process is reduced. In addition, when the clip 140 is driven by the elastic buckle 130 to return to its original position, the plastic body 100 and the aluminum alloy frame 200 provide a restraining force therebetween to achieve the limiting.
