Embodiment 1

[0046] Due to the wide variety of existing portable electrical appliances and the different shell shapes, it is impossible to give a comparative explanation one by one. The technical principle of the present invention will be specifically explained below by taking the impact-resistant protective shell of a mobile phone as an example. Such as figure 1 , figure 2 , image 3 and Figure 4 The impact-resistant protective shell of the portable electrical appliance of the present invention shown is specifically the impact-resistant protective shell of a mobile phone, including a protective shell 1 adapted to the shape of the mobile phone (not shown in the figure), and the protective shell 1 is made of elastic PVC material to protect The eight corners of the shell are all provided with a buffer body 2 that protrudes to the outside of the protective shell. The shape of the buffer body 2 is a partial sphere, and the buffer body 2 is also made of elastic PVC material. One. In this ...

Embodiment 2

[0053] In the present invention, not only the shape of the buffer body can be varied, but also its structure can be varied. Such as Figure 5 The difference between the impact-resistant protective shell of the portable electrical appliance of the present invention and the first embodiment is that the protective shell 1 is made of hard plastic material, and the buffer body is provided with a helical spring structure. The helical spring structure is composed of a protective cover 4 and a helical spring 5. The protective cover is made of stainless steel plate, the coil spring 5 is made of stainless steel wire, the upper part of the coil spring 5 is welded and fixed with the protective cover 4, and its lower end is anchored in the protective shell 1, and the axial direction of the coil spring 5 is along the The main buffer axis direction setting of the buffer body.

Embodiment 3

[0058] Such as Figure 6 The difference between the impact-resistant protective case of the portable electrical appliance of the present invention and the second embodiment is that the buffer body is a curved spring structure, and the curved spring structure is composed of a protective cover 4 and a curved spring 6, wherein the protective cover 4 is made of plastic, and the curved Spring 6 is made of spring steel wire, and the top of curved spring 6 is fixed in protective cover 4, and its lower end is anchored in protective shell 1, and the maximum deformation direction of curved spring 6 is arranged along the main buffer axis direction of buffer body.

[0059] Similar to Embodiment 2, the bending spring structure can also be made of metal material, or rubber material, or polyurethane material, or plastic material, or be made of composite materials mentioned above, and is not limited to the materials mentioned in this example , as long as it can play a good buffer effect, the ...

Abstract

The invention relates to a shockproof protective shell of a portable electric appliance. The shockproof protective shell of the portable electric appliance comprises a protective housing which is additionally arranged on the surface of the portable electric appliance and adapts to the shape of the portable electric appliance. The shockproof protective shell is characterized in that a cushioning body which is raised to the exterior of the protective housing is arranged at the corner part or / and in the vicinity of the corner part of the protective housing. The shockproof protective shell disclosed by the invention can overcome the defect that the cushioning provided by the protective housing in the prior art is limited by the thickness in a very limited manner, and the cushioning body is arranged at the corner part and in the vicinity of the corner part of the housing, so that the cushioning stroke is greatly improved, the shock force of the portable electric appliance when the portable electric appliance falls to the ground accidentally is reduced, the shockproof performance of the local part is improved and the corner part of the housing of the electric appliance can be effectively protected from being damaged when bearing the external shock; and the shockproof protective shell has the advantages of simple structure, various forms, vivid and interesting properties and strong practicability, and can be widely applied to mobile phones, Walkmans, electronic dictionaries, ipads, digital cameras, mobile hard disks, GPS (global positioning system) navigation systems, notebook computers, calculators and other portable electric appliances so as to have very broad market application prospects.

Description

technical field [0001] The invention belongs to the technical field of supporting products of portable electrical appliances such as mobile phones, and relates to a protective case placed on the surface of the portable electrical appliance, in particular to a protective case with better impact resistance. Background technique [0002] With the progress of society, portable electrical appliances such as mobile phones have increasingly become an indispensable tool in people's life. Taking mobile phones as an example, various mobile phones with comprehensive functions and gorgeous appearance are emerging in an endless stream. Many mobile phones are expensive. In order to prevent the surface of the mobile phone from being worn or scratched during daily use, many people choose to equip their mobile phones with a protective shell. At present, the protective casings of mobile phone products on the market are generally made of rubber and plastic injection molding technology. After u...
