The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.

[0010] The term "comprising" means "including, but not necessarily limited to"; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.

[0011] Embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0012] FIG. 1 illustrates an embodiment of a protective cover 100. As illustrated in FIG. 1, the protective cover 100 includes a housing 10, a connecting portion 20, and a ring 30.

[0013] The housing 10 includes a back portion 101 and a resisting portion 102. The resisting portion 102 is extended from the edge of the back portion 101 and a receiving cavity is formed between the back portion 101 and the resisting portion 102. The housing 10 is made to receive and protect an electronic device. One or more through holes 1021 are defined on the resisting portion 102 or the back portion 101 for exposing one or more elements of the electronic device, such as a charging interface, an earphone interface, a camera, a loudspeaker, and the like.

[0014] The connecting portion 20 is extended from the back portion 101 in a direction which is away from the back portion 101. An angle .alpha. (see FIG. 4) is formed between the connecting portion 20 and the back portion 101, and the angle .alpha. is more than 0.degree. and less than 180 degrees. In at least one embodiment, the angle .alpha. is 90 degrees.

[0015] The ring 30 is positioned at an end portion of the connecting portion 20. The ring 30 is configured for allowing insertion of a user's finger when the electronic device is handheld, which can prevent the electronic device received in the protective cover being dropped, as shown in FIG. 2. The ring 30 is ring-shaped, and may be circular, oval, square, or any irregular shape allowing for insertion of finger. In at least one embodiment, the ring 30 is circular.

[0016] A groove 103 is defined on the back portion 101. The groove 103 matches the connecting portion 20 and the ring 30, for receiving the connecting portion 20 and the ring 30. As illustrated in FIG. 3 and FIG. 4, the ring 30 and the connecting portion 20 can be received in the groove 103 under a pressing force towards the back portion 101.

[0017] In detail, the groove 103 includes a first groove 1031 and a second groove 1032. The first groove 1031 matches the connecting portion 20 for receiving the connecting portion 20. The second groove 1032 is a groove matching the outlines of the ring 30, for receiving the ring 30. The second groove 1032 forms an interference fit with the ring 30. The ring 30 can be deformed to be received in the second groove 1032 under the pressing force. In reverse, the ring 30 can be deformed to be pulled out of the second groove 1032 under a pulling force.

[0018] A recess 104 is defined on the back portion 101 near the edge of the groove 103. When the connecting portion 20 and the ring 30 are received in the groove 103, the recess 104 is configured to enable the user to pull the connecting portion 20 or the ring 30 out of the groove 103. In at least one embodiment, the recess 104 is defined near an inside edge of the second groove 1032. In other embodiments, the recess 104 can be defined near an outside edge of the second groove 1032.

[0019] The connecting portion 20 is made of thermoplastic polyurethane rubber. In at least one embodiment, the housing 10, the connecting portion 20, and the ring 30 are integral, the connecting portion 20 and the ring 30 are formed by injecting from the back portion 101 of the housing 10. In some embodiments, the housing 10 and the connecting portion 20 are integral, the ring 30 being fixed to the connecting portion 20. In other embodiments, only the connecting portion 20 and the ring 30 are integral, the connecting portion 20 being rotatably connected to the back portion 101 of the housing 10.

[0020] The number of the connecting portions 20 and rings 30 can be based on demand, and if more than one, the connecting portions 20 and rings 30 are defined on multiple positions of the back portion 101 for insertion of different fingers.

[0021] The ring 30 allows insertion of user's finger, thus the electronic device received in the protective cover 100 can be held more firmly and securely. When the electronic device is not being used, the ring 30 can be pressed into the groove 103 on the back portion 101.

[0022] It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments of the present disclosure.
