Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Several embodiments of the invention are given in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 6, a protection bracket 100 according to an embodiment of the present invention is shown fixed on a subframe body 200, where the protection bracket 100 includes a mounting structure 110, a contact structure 130, and an elastic structure 120 connecting the mounting structure 110 and the contact structure 130, the contact structure 130 includes a first contact portion 131 and two second contact portions 132, the two second contact portions 132 are spaced apart from each other and are disposed on opposite sides of the first contact portion 131, the first contact portion 131 and the second contact portion 132 are coplanar at the bottom end, the height of the bracket is greater than the thickness of the battery pack, and the mounting structure 110 is fixed on the subframe body 200.

The first contact portion 131 is disposed obliquely to the elastic structure 120. The two second contact portions 132 are symmetrically disposed with respect to the first contact portion 131. One end of the second contact portion 132, which is far away from the first contact portion 131, is provided with a rolling lug 133, the rolling lug 133 is smoothly connected with the second contact portion 132, and the elastic structure 120 is provided with a plurality of bends. The resilient structure 120 is smoothly connected to the mounting structure 110. Two mounting holes are arranged on the mounting structure 110 at intervals, and each mounting hole comprises a positioning hole 111 and a fixing hole 112.
