Description

[Technical Field]

[0001] The present invention relates to an improved protective case for a portable electronic device, and in particular to a protective case for a portable electronic device that is easy to install, simple and easy to operate and use, allows the strap to be easily, quickly, and freely attached and detached to the protective case, and the strap assembled to the protective case has strong positioning and is not easily damaged, making it safe and economical to use, and highly satisfies practical applicability, ideality, and inventiveness. [Background technology]

[0002] Various portable electronic devices, such as mobile phones, tablet PCs, handheld computers, personal multimedia players, etc., have become indispensable items in people's lives. To enhance the convenience of using such portable electronic devices, most portable electronic devices are currently equipped with protective cases, and the portable electronic devices can be protected and conveniently operated by operating the protective case.

[0003] The protective case for the portable electronic device is available in various styles and types to accommodate various different usage needs and operating habits. As shown in Figures 1 and 2, the protective case for the portable electronic device 10 has a first surface 101, which is used to place the portable electronic device 20, a second surface 102 opposite the first surface 101, and a belt 30 on the second surface 102. The belt 30 is usually made of an elastomer such as silicon or rubber, and can be elastically attached to the second surface 102 when not in use (see Figure 1). (See FIG. 1), when the belt 30 is unfolded, a storage space A is formed between the belt 30 and the second surface 102 for inserting the user's palm or fingers. Thus, when the portable electronic device 20 is placed in the protective case 10 and the user further grasps and operates the protective case 10 with his / her hand, the elastic fastening force of the belt 30 against the palm or fingers prevents the portable electronic device 20 placed in the protective case 10 from falling off, which has the effect of enhancing the safety of using the portable electronic device 20.

[0004] As described above, there are two main ways in which the belt 30 can be attached to the protective case 10. One is to directly fasten both ends of the belt 30 to the protective case 10. Although this type of configuration can achieve the positioning effect of the belt 30, if the belt 30 is damaged, deformed, or becomes unusable, the belt 30 cannot be replaced and the only option is to replace the entire protective case, which is relatively wasteful and economical. As shown in FIG. 3, the belt 30 has a flexible sleeve 301 integrally formed on each end thereof. A hole 103 and a positioning groove 104 are provided at a position corresponding to the protective case 10 for the flexible sleeve 301 to penetrate and position. The flexible sleeve 301 is drilled into the protective case 10, and is then penetrated by a positioning pin 40 to be positioned in the positioning groove 104. This allows the belt 30 to be detachably attached to the protective case 10 and to be replaceable. This is an operational form that can improve the aforementioned lack of the belt 30 being fixed to the protective case 10. However, after the positioning pin 40 penetrates the soft sleeve 301 and positions it in the positioning groove 104, a large elastic force is generated when the belt 30 is expanded and operated. As a result, the soft sleeves 301 at both ends of the belt 30 are directly subjected to a tensile force. With continuous operation, the most common problem is that both sides of the soft sleeve 301 are easily torn, and the soft sleeve 301 is quickly broken and damaged, requiring the belt 30 to be replaced. This makes the belt 30 easily damaged, and is therefore inconvenient, uneconomical, and unsafe to use. Furthermore, in order to provide sufficient support to both ends of the belt 30 when the belt 30 is unfolded and operated, the positioning pins 40 are usually made of metal, which not only increases costs but also makes the operation cumbersome, inconvenient and time-consuming, especially in the embodiment in which the user inserts the positioning pins 40 into the soft sleeves 301 one by one and then places them in the positioning grooves 104. Summary of the Invention [Problem to be solved by the invention]
