DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides a composite aluminum plate with impact resistance, which includes a composite aluminum plate substrate 1. A connecting plate 2 is arranged at the bottom of the composite aluminum plate substrate 1. A bottom plate 3 is arranged below the connecting plate 2. A keel frame 4 is arranged inside the bottom plate 3. A plurality of accommodating cavities 5 are formed between the keel frame 4 and the bottom plate 3. An impact resistance unit 6 is arranged inside each accommodating cavity 5. The impact resistance unit 6 includes a movable plate 61 and a spring 62. The spring 62 is fixed at the central position of the bottom surface of the movable plate 61. The top surface of the movable plate 61 is bonded to the bottom surface of the connecting plate 2. The connecting plate 2 is movably arranged inside the bottom plate 3. The bottom of the spring 62 is fixed on the surface of the bottom plate 3.

[0023] Please refer to Figure 1 , 2 , 3 and 4. When the composite aluminum plate substrate 1 is impacted, the composite aluminum plate substrate 1 can drive the connecting plate 2 to move towards the bottom plate 3. At this time, the connecting plate 2 will squeeze the movable plate 61, and the movable plate 61 will move inside the accommodating cavity 5. When the movable plate 61 moves, it can compress the spring 62, converting a part of the impact force into the potential energy of the spring 62. The composite aluminum plate substrate 1 is buffered by a plurality of springs 62. Since the composite aluminum plate substrate 1 will move as a whole when impacted, the connecting plate 2 can simultaneously squeeze all the springs 62 to deform and store energy, so that the impact force is evenly dispersed into each spring 62, thereby buffering and protecting the composite aluminum plate substrate 1.

[0024] A support column 7 is fixedly arranged at the central position of the top of the movable plate 61. Connecting holes 8 are arranged on the surfaces of the connecting plate 2 and the composite aluminum plate substrate 1. The top end of the support column 7 extends into the connecting hole 8.

[0025] Please refer to Figure 3 and 5 , the support column 7 can extend into the connecting hole 8 at an angle perpendicular to the connecting plate 2. For the connecting plate 2 and the composite aluminum plate substrate 1, the support column 7 can increase the overall strength inside the connecting plate 2 and the composite aluminum plate substrate 1, thereby further improving the impact resistance of the composite aluminum plate substrate 1.

[0026] The inner wall of the accommodating cavity 5 is fixedly provided with a T-shaped limiting block 9. The bottom of the movable plate 61 is fixedly provided with a sliding seat 11 through a support plate 10. The sliding seat 11 is slidably arranged on the surface of the T-shaped limiting block 9. The support plate 10 is inclined. The bottom of the movable plate 61 is fixedly provided with a guide rod 12. A fixing rod 13 is sleeved on the surface of the guide rod 12. The bottom of the fixing rod 13 is fixedly arranged on the surface of the bottom plate 3.

[0027] Please refer to Figure 2 , 3 and 4. When the movable plate 61 moves, it can drive the sliding seat 11 to move synchronously through the support plate 10. The sliding seat 11 can slide on the surface of the T-shaped limiting block 9. The cooperation between the sliding seat 11 and the T-shaped limiting block 9 can limit the movement track of the movable plate 61 to a straight line perpendicular to the bottom plate 3. And when the movable plate 61 moves, it can drive the guide rod 12 to move synchronously inside the fixing rod 13. The guide rod 12 and the fixing rod 13 can also limit the movement track of the movable plate 61 to a straight line perpendicular to the bottom plate 3. At this time, the movable rod, the fixing rod 13, the keel frame 4 and the support plate 10 can form a stable triangular structure to support the movable plate 61 and average the impact force received by the bottom plate 3.

[0028] Although the embodiments of the present invention have been shown and described, for those skilled in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
