Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood that 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. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

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 and 2, the present invention provides an outer frame 100, wherein the outer frame 100 can be deformed by an external force and then sleeved outside a housing 200 to protect the housing 200. The outer frame 100 is integrally formed, and the outer frame 100 includes a frame 10, a plurality of positioning posts 20 and a plurality of fixing members 30. The frame 10 is sleeved outside the housing 200 for protecting the housing 200. The positioning posts 20 and the fixing members 30 are disposed on the surface of the frame 10 close to the housing 200. The positioning posts 20 are used to position the frame 10. The fixing member 30 is used to fix the frame 10 to the housing 200.

Specifically, referring to fig. 3, the frame 10 includes four sidewalls 11 and a connecting portion 12. The four side walls 11 are connected in sequence by four connecting portions 12. In this embodiment, the four sidewalls 11 are provided with positioning posts 20 and fixing members 30 to position and fix the four sidewalls 11 on the housing 200 respectively. The four side walls 11 are further respectively provided with avoidance grooves 111 according to shapes of structures, parts and the like on the housing 200 adjacent to the side walls, and avoidance holes 112 according to structures, pore passages and the like on the housing 200 to be exposed.

The housing 200 is provided with a plurality of positioning holes 201, and the positioning posts 20 are disposed on the surface of the sidewall 11 close to the housing 200 corresponding to the positioning holes 201 to position the sidewall 11 on the housing 200, so as to prevent the sidewall 11 from deviating.

In this embodiment, two positioning pillars 20 are disposed on each side wall 11, but the present invention is not limited thereto, and in other embodiments, the number of the positioning pillars 20 disposed on each side wall 11 may be selected according to needs, such as one, three or more, and the like.

The housing 200 further has a plurality of fixing holes 202, and the fixing member 30 includes an upper hook 31 and a lower hook 32. The upper hooks 31 and the lower hooks 32 are respectively disposed on the surface of the sidewall 11 close to the housing 200 in the opposite directions and respectively correspond to a corresponding fixing hole 202 on the housing 200 to fix the sidewall 11 on the housing 200, so as to prevent the sidewall 11 from moving relative to the housing 200.

In this embodiment, two fixing members 30 are disposed on each of the side walls 11, but the invention is not limited thereto, and in other embodiments, the number of the fixing members 30 disposed on each of the side walls 11 may be selected according to needs, such as one, three or more.

During the installation operation, firstly, the four side walls 11 of the frame body 10 are deformed and expanded outwards in the direction away from the other side walls 11 by the action of external force, so that the internal space of the frame body 10 is enlarged, and the positioning columns 20 and the fixing pieces 30 on the side walls 11 can be retracted from the shell 200; subsequently, the housing 200 is placed in the frame 10, the external force is withdrawn, the side walls 11 are restored under the restoring force of the elastic deformation, each side wall 11 is positioned at a proper position on the housing 200 by the positioning columns 20 on each side wall 11 matching with the positioning holes 201 on the housing 200, each side wall 11 is fixed on the housing 200 by the upper hooks 31 and the lower hooks 32 on each side wall 11 matching with the fixing holes 202 on the housing 200, and the installation of the outer frame 100 is completed.

In this embodiment, the outer frame 100 is injection molded by plastic material, but not limited thereto, in other embodiments, the outer frame 100 may also be processed by metal, alloy, or other materials with elastic deformation.

The frame 100 is integrated, the periphery of the frame 10 is expanded by external force, then the housing 200 is placed in the withdrawing external force, the frame 10 is restored to the original state, the positioning column 20 arranged on the frame 10 positions the frame 10 to a proper position on the housing 200, and then the frame 10 is fixed firmly by the fixing member 30. The outward appearance is clean and tidy, simple structure, mounting means easy operation to it is fixed firm, solved and torn open the piece and lead to outward appearance and clearance to be influenced the problem, saved the unnecessary part simultaneously, the cost is lower.

In addition, other modifications within the spirit of the invention may occur to those skilled in the art, and such modifications are, of course, included within the scope of the invention as claimed.
