A limiting groove 5 is provided on the support platform 4. The buffer sponge 3 is arranged in the limiting groove 5. The upper surface of the buffer sponge 3 is against the inner surface of the metal outer plate 1.

[0023] During the installation of the metal outer panel 1, since a support platform 4 is provided on the plastic base plate 2, and a buffer sponge 3 is installed between the support platform 4 and the metal outer panel 1, the upper surface of the buffer sponge 3 is against the inner surface of the metal outer panel 1. Therefore, after the installation of the metal outer panel 1 is completed, the buffer sponge 3 is in a pre-pressed state, which can ensure the support of the buffer sponge 3 for the metal outer panel 1, and can also reduce the frequency of collisions between the metal outer panel 1 and the plastic base plate 2, and can also avoid the sharp metal collision sound when the metal outer panel 1 collides with the plastic base plate 2, thereby ensuring the user experience and also ensuring the service life of the metal outer panel 1.

[0024] In this embodiment, the limiting groove 5 includes a first limiting rib 51, a second limiting rib 52, a third limiting rib 53 and a fourth limiting rib 54.
