[0030] Please refer to Figures 1 to 6 , which shows the specific structure of the preferred embodiment of the present application, including exoskeleton 10, shell 20 and spring assembly 30.

[0031] The shell 20 is provided with two, and the two shells 20 are respectively located on the two sides of the exoskeleton 10 and are hinged with the exoskeleton 20. Through the arrangement of the exoskeleton 10, the connection between the two shells 20 is protected. Each shell 20 is provided with a mounting cavity 201 matched with an external mobile phone. The mounting cavities 201 in the two shells 20 are communicated together, and in use, the two folded parts of the external mobile phone are loaded into the corresponding shells 20. In this embodiment, the exoskeleton 10 integrally extends an installation plate 11. The two shells 20 are provided with a bracket 21 on the side facing the exoskeleton 10. The bracket 21 includes a main body 211 and a connecting part 212 protruding from the front and rear sides of the main body 211. The connecting part 212 is hinged with the installation plate 11 through a rotating screw 12. The bracket 21 is made of metal material, which ensures the structural stability of the connection between the shell 20 and the exoskeleton 10. One of the shells 20 is provided with a through slot 202 for exposing a mobile phone sub-screen and a through hole 203 for exposing a mobile phone camera. The through slot 202 and the through hole 203 are respectively communicated with the corresponding mounting cavities 201. The number and position of the through slot 202 and the through hole 203 are adjusted according to the actual product. The inner side wall of the exoskeleton 10 is recessed inwardly and provided with two accommodation grooves 101 matched with the clockwork assembly 30.

[0032] The clockwork assembly 30 is provided with two, and each clockwork assembly 30 is arranged in the inner side of the exoskeleton 10. The outer end of the clockwork assembly 30 is respectively connected with the corresponding shell 20 and covers the connection between the exoskeleton 10 and the corresponding shell 20, thereby sealing the connection between the exoskeleton 10 and the corresponding shell 20 and preventing external dust from entering, which effectively improves the user's experience. The outer end of the clockwork assembly 30 is pulled tight and retracted under the action of its own elasticity, so that it does not need to be provided with an additional rebound structure, and the overall structure is simpler. In this embodiment, the outer end of the clockwork assembly 30 is riveted and fixed with the main body 211. When the shell 20 is rotated to fold the mobile phone, the main body 211 pulls the outer end of the clockwork assembly 30 outward. When the mobile phone is opened, the outer end of the clockwork assembly 30 is retracted and reset under the action of its own elasticity. The inner end of the clockwork assembly 30 is arranged in the corresponding accommodation groove 101. When the inner end of the clockwork assembly 30 is installed on the exoskeleton 10, the installation position of the clockwork assembly 30 can be limited through the accommodation groove 101, which ensures the installation accuracy.

[0033] Each spring assembly 30 comprises a fixed shaft 31 fixed inside the exoskeleton 10, in this embodiment, the two ends of the fixed shaft 31 are fixedly installed on the exoskeleton 10 by spot welding, and a spring 32 connected to the fixed shaft 31 and wound on the fixed shaft 31, the outer end of the spring 32 is fixedly connected with the corresponding shell 20 and covers the connection between the exoskeleton 10 and the corresponding shell 20, and the outer end of the spring 32 is pulled tight and retracted under the action of its own elastic force.

[0034] The assembly process of this embodiment is as follows:

[0035] During assembly, one end of the spring 32 is fixed and wound on the fixed shaft 31, thereby assembling two spring assemblies 30, then the two ends of the fixed shaft 31 of the two spring assemblies 30 are fixed in the accommodation groove 101 on the exoskeleton 10 by spot welding, then the two shells 20 and the corresponding brackets 21 are fixed together, then the spring 32 is adjusted to a loose state, and the outer end of the spring 32 is riveted to the corresponding bracket 21, then the bracket 21 and the exoskeleton 10 are hinged together by rotating the screw 12, and the spring 32 is ensured to be under contraction stress, thereby completing the overall assembly process.

[0036] The design focus of the utility model lies in: the exoskeleton is provided, so that the exoskeleton plays a protective role on the connection between the two shells, and the spring assembly is provided in two, each spring assembly is arranged inside the exoskeleton, and the outer end of the spring assembly is connected with the corresponding shell and covers the connection between the exoskeleton and the corresponding shell, so that the sealing performance of the connection between the exoskeleton and the shell is improved by the spring, external dust is prevented from entering the inside, and the outer end of the spring assembly is pulled tight and retracted under the action of its own elastic force; no other rebound structure needs to be added, and the overall structure is also simpler.

[0037] The above is only a preferred embodiment of the utility model, and does not limit the technical range of the utility model, so any slight modification, equivalent change and modification according to the technical essence of the utility model of the above embodiment still belongs to the range of the technical scheme of the utility model.
