As shown in fig. 28 to 29, in the present embodiment, one end of the first limiting plate 906 is fixed to the bumper stay 1022, and the other end is connected to the elastic stay 905. The first end 909 of the first limiting plate 906 may be welded to the bumper bracket 1022. The first limiting plate 906 may be disposed at an angle to the bumper bracket 1022, and of course, the first limiting plate 906 may also be perpendicular to the bumper bracket 1022. A groove 910 is provided on the second end of the first limiting plate 906, the groove 910 extends towards the inside of the first limiting plate 906 along the second end, and the groove 910 is used for fixing the elastic support 905, i.e. placing the elastic support 905 in the groove 910.

As shown in fig. 27, 29-30, in this embodiment, the elastic support 905 may include a base 911, a first supporting body 912, a limiting block 913, and a second supporting body 914. The base 911 is connected to the first support 912, i.e. the first support 912 is vertically disposed on the base 911. The limiting block 913 is located on the first support 912, the limiting block 913 is, for example, a cube structure, the first support 912 is, for example, a cylinder structure, and the base 911 is, for example, a cylinder structure. The width of the limiting block 913 is greater than that of the first supporting body 912, and the width of the limiting block 913 is smaller than that of the base 911. Of course, the width of the stopper 913 may be equal to the width of the base 911. The stopper 913 is provided with a second support 914. The height of the second supporter 914 may be greater than that of the first supporter 912. The width of the second supporter 914 gradually increases from the bottom to the top, and the thickness of the second supporter 914 gradually decreases from the bottom to the top, that is, the top of the second supporter 914 has a larger area. Fixing holes 915 are further provided on the top of the second support body 914, and when the top of the second support body 914 is attached to the connection plate 904, the fixing holes 915 are aligned with the connection holes on the connection plate 904, and then bolts are placed in the fixing holes 915 and the connection holes, so that the elastic bracket 905 can be fixed on the front case 902. In this embodiment, since the top of the second support 905 has a larger surface area, the second support 905 and the connection plate 904 have a larger contact area, and thus the connection stability can be improved.
