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.

The protective shell provided by the embodiment of the invention is used for protecting the shell of foldable electronic equipment, in particular to protecting the shell of a notebook computer. Of course, in other embodiments of the present invention, the protective shell can also be used for protecting other shells, and is not limited herein.

As shown in fig. 1, an embodiment of a protective case. For protection of the notebook computer housing 100. The notebook computer housing 100 includes a host housing 110 and a display housing 120. A protective case includes a first inner case 210, a first outer case 220, a second inner case 230, and a second outer case 240. The first inner case 210 is disposed on a side of the display outer case 120 away from the host outer case 110. The second inner case 230 is disposed on a side of the host outer case 110 away from the display outer case 120. Specifically, the outer edge of the first inner case 210 has a plurality of first protrusions 211. In this embodiment, the number of the first protrusions 211 is four. The four first protrusions 211 correspond to four corners of the display housing 120, respectively. Further, a first groove 212 is formed on a surface of the first inner case 210 away from the display housing 120. The first groove 212 extends to an outer edge of the first protrusion 211. The first housing 220 is made of TPU-like material. The first housing 220 is disposed within the first recess 212. And the first housing 220 is mated with the first recess 212. The groove bottom of the first groove 212 is mostly an arc surface, which is beneficial for the first outer shell 220 to be attached to the first inner shell 210. And the groove bottom extending to the first protrusion 211 is a plane. Since the first groove 212 extends to the outer edge of the first protrusion 211, the first housing 220 extends to the outer edge of the first protrusion 211 along with the first groove 212. Since the first protrusion 211 is located at the outermost side of the first inner case 210, the first protrusion 211 may first contact the ground against an impact force when the notebook is dropped. Then, the impact force is transmitted to the first housing 220 through the first protrusion 211, i.e., the impact force is transmitted to the first housing 220 through the thin-walled structure of the groove wall of the first groove 212 on the first protrusion 211. Because the thin-walled structure is when resisting the impact force, the deflection itself is great, and it can effectively offset the impact force with the first shell 220 that elastic material made combines together, and it is obvious to rely on the deformation characteristic promotion of material itself to prevent falling the ability than only. The second inner case 230 is disposed on a side of the host outer case 110 away from the display outer case 120. The second outer housing 240 is disposed on a side of the second inner housing 230 away from the host outer housing 110. In this embodiment, the first housing 220 is made of TPU material, and it should be understood that in other embodiments, the first housing 220 may also be made of other elastic materials, such as TPE material in soft plastic.

Referring to fig. 1-5, the first groove 212 has a first groove wall 2121 and a second groove wall 2122. The first groove wall 2121 extends annularly along the outer edge of the first inner case 210. The first groove 212 is defined annularly by a first groove wall 2121 and a second groove wall 2122. It will be appreciated that in other embodiments, the first groove 212 has only a first slot wall 2121 extending annularly along the outer edge of the first inner housing 210. In this embodiment, the first recess 212 is left-right symmetric with respect to the left-right symmetric axis of the display housing 120. The first recess 212 is protruded downwardly at the middle of the upper portion of the display housing 120. The first recess 212 is protruded upward at the middle of the lower portion of the display housing 120. The width of the first groove 212 is gradually decreased from the middle portion to the corresponding first protrusion 211, which is more favorable for the attenuation of the impact force on the first housing 220. In this embodiment, the first inner housing 210 has a first receiving groove 213, and the display housing 120 is received in the first receiving groove 213. A plurality of first buckles 2131 are disposed on a wall of the first receiving groove 213. The display housing 120 is fixed in the first receiving groove 213 by the first fastener 2131. It is understood that in other embodiments, the display housing 120 may be fixed in the first receiving groove 213 by other means, for example, by bonding or by directly sleeving the first inner shell 210 on the display housing 120. Further, the first housing 220 is partially received in the first recess 212. So that a surface of the first outer case 220 remote from the first recess 212 protrudes outward from the first inner case 210. In this embodiment, the first inner case 210 is made of transparent engineering plastic. In particular to PC material in transparent engineering plastic. Specifically, in this embodiment, the area surrounded by the second slot wall 2122 is not covered by the first shell 220. Thus, the second slot wall 2122 defines a transparent region that is easily scratched or soiled during use. Since the first outer shell 220 is made of TPU material, it has wear resistance and protrudes out of the first inner shell 210. Therefore, in the daily use process, the first outer shell 220 protects the first inner shell 210, and the first inner shell 210 is prevented from being worn and scratched in the use process. In particular to prevent the transparent areas from becoming dirty due to abrasion and scratching. In this embodiment, the first slot wall 2121 is provided with a first through slot 2121 a. The first groove 212 communicates with the first through groove 2121 a. The first housing 220 has a first extension 221 that may protrude outward from the first through slot 2121 a. The first extension part 221 is integrally provided with the first housing 220. Since the first extension 221 is extended outward from the first through groove 2121a, when the first housing 220 needs to be replaced, the first housing 220 can be removed from the first groove 212 by the first extension 221.

Referring to fig. 1 and fig. 6 to 9, in the present embodiment, the second inner shell 230 has a second receiving groove 231, and the host outer shell 110 is received in the second receiving groove 231. A plurality of second hooks 2311 are disposed on the groove wall of the second receiving groove 231. The host housing 110 is fixed in the second receiving groove 231 by the second latch 2311. It is understood that in other embodiments, the host housing 110 may be fixed in the second receiving groove 231 by other means, for example, by bonding or by directly sleeving the second inner shell 230 on the host housing 110. The groove wall of the second receiving groove 231 corresponding to both sides of the rear end of the main body case 110 is provided with an anti-slip protrusion 2312. The escape prevention protrusion 2312 is made of an elastic material. When the host housing 110 is received in the second receiving groove 231, the slot walls of the second receiving groove 231 corresponding to the front end and the rear end of the host housing 110 clamp the front end and the rear end of the host housing 110, and the anti-slip protrusion 2312 further improves the clamping force. Further, a second groove 232 is formed on a surface of the second inner housing 230 away from the main body housing 110. The second groove 232 has a third groove wall 2321. The third slot wall 2321 extends annularly along the outer edge of the second inner case 230. The second groove 232 is scaled down approximately to the dimensions of the second housing 240. The second housing 240 is received in the second groove 232 to fill the portion of the second housing 240 missing due to the second groove 232. In this embodiment, the second housing 240 is made of TPU material, and it is understood that in other embodiments, the second housing 240 may also be made of other elastic materials, such as TPE material in soft plastic. The second outer shell 240 is located outside the second inner shell 230, and wraps the second inner shell 230, so that the second outer shell 240 made of TPU material can effectively prevent the second inner shell 230 from being worn and scratched in the daily use process, especially when the notebook is placed on a desk. And because the TPU material is an elastic material, the TPU material has the characteristic of softness, and the anti-skid property of the notebook computer is improved. Further, the groove bottom of the second groove 232 is provided with a plurality of second protrusions 2322 for positioning. The second housing 240 is provided with a third groove 241 matching with the second protrusion 2322. The groove bottom of the third groove 241 protrudes from the side of the second outer case 240 away from the second inner case 230. Specifically, the second protrusion 2322 is segment-shaped and smaller than a hemisphere. The second protrusion 2322 also has a third protrusion 2322a extending toward the third slot wall 2321. The third protrusion 2322a is bar-shaped. Since the second housing 240 is made of an elastic material, it has elasticity itself. When the second protrusion 2322 is engaged with the third groove 241, the third protrusion 2322a is in interference fit with a fourth groove 2411 of the third groove 241 corresponding to the third protrusion 2322 a. The interference fit improves the bonding force between the second protrusion 2322 and the third groove 241 while satisfying the positioning requirement, and further improves the bonding force between the second outer case 240 and the second inner case 230. Since the third protrusion 2322a extends toward the third slot wall 2321, that is, the third protrusion 2322a extends toward the outside of the second inner housing 230, when the second outer housing 240 needs to be replaced, the second outer housing 240 is lifted from the second groove 232 by a certain gap from the third slot wall 2321, and air firstly enters between the third protrusion 2322a and the fourth groove 2411, which is beneficial to expanding the gap, and is convenient for detaching the second outer housing 240 from the second groove 232. Further, the second inner case 230 and the second outer case 240 also have a trace notch 250 for routing the notebook computer. In this embodiment, the trace notch 250 is located at two sides of the rear end of the host housing 110. The corner of the second inner case 230 corresponding to both sides of the front end of the host outer case 110 is provided with a fourth protrusion 233 for preventing falling. The second outer case 240 is provided with a fifth protrusion 242 overlapping the second inner case 230. The first protrusion 211, the fourth protrusion 233, and the fifth protrusion 242 are all arc-shaped.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
