The new model relates to a protective case, in particular to a mobile phone protective case covering the exterior of a smart phone.

Smartphones have become an indispensable tool in the daily life of modern people. In addition to communication, smart phones integrate functions such as entertainment, information collection and mobile payment. Therefore, smartphones need to be properly protected so that when they are lost or damaged, many data are lost along with them, and relatively many things cannot be done. The most basic product that protects a smartphone is a phone case.

Smartphones may require different supports depending on the scene. For example, if a user wants to place a smartphone on a desktop to watch an album, a support frame capable of supporting the smartphone on the desktop at an angle is required. If the user wants to hang the smartphone in the air, such as for fixed-point photography, a set of hooks is required at this time. Whether it is a support frame or a hook, it can only be used in certain scenarios, and the occurrence of these scenarios cannot be expected, but it is obviously cumbersome to carry the support frame or the hook with the mobile phone. If the mobile phone protective case can provide the above-mentioned related functions without increasing the structural size and detracting from the functionality, it has always been a good product expected by consumers. However, this product is not yet available on the market.

Therefore, the creator of the new type has designed a mobile phone protective case based on years of R&D and production experience to meet the above requirements.

The present invention will be described more specifically by referring to the following embodiments.

Please refer to FIGS. 1 and 6 . FIG. 1 is a front view of the mobile phone protective case 1 according to the new embodiment, and FIG. 6 is a rear view of the mobile phone protective case 1 according to the new embodiment. The mobile phone protective case 1 in FIG. 1 covers a smart phone, and only the lens module 2 of the smart phone is exposed on the mobile phone protective case 1 . The mobile phone protective case 1 includes an elastic protective frame 10, a protective back plate 20 and four rotating support structures (for the convenience of description, these rotating support structures are the first rotating support structure 31 in the upper left of FIG. 1 and the second rotating support structure in the upper right). The rotating support structure 32, the third rotating support structure 33 at the lower left and the fourth rotating support structure 34 at the lower right). The appearance structure and material of the aforementioned technical components, and the usage of the mobile phone protective case 1 will be described in detail below.

The elastic protective frame 10 has the appearance of a rectangle with rounded corners, and is used for wrapping the four sides of the smart phone. In practice, the material of the elastic protective frame 10 can be thermoplastic polyurethane (Thermoplastic Polyurethane, TPU). The elastic protective frame 10 can have different designs according to the operation interface of the smart phone designed on the four sides. The elastic protection frame 10 includes a plurality of through holes and protruding structures, the through holes correspond to the connecting ports or switches of the smart phone, and the protruding structures correspond to the physical buttons of the smart phone. For example, there is a switch through hole 11 on the side of FIG. 1 for exposing the switch of the smart phone. Since the switch through hole 11 cannot be viewed directly, its position is shown with a dotted line. This is also the case for other elements shown in dotted lines in this embodiment. For another example, there is a power connection port through hole 12 under the elastic protection frame 10 for exposing the power connection port of the smart phone. In addition, key protruding structures 13 are correspondingly provided around the elastic protection frame 10 , and the key protruding structures 13 conveniently correspond to a physical key respectively. Preferably, a plurality of sound guide holes 18 are opened under the elastic protection frame 10 to match the speaker position of the smartphone, as shown in FIG.

The protective back plate 20 is combined with one side of the elastic protective frame 10 to protect the back of the smart phone. Generally speaking, the purpose of installing a mobile phone case on a smartphone is not only to prevent impact damage, but also to prevent scratches on the surface. If the material of the protective back plate 20 is not scratch-resistant, the scratched part is also will be a disadvantage in appearance. Therefore, in practice, the material of the protective back plate 20 is preferably polycarbonate (Polycarbonate, PC), which is scratch-resistant and firm. In addition, the polycarbonate is transparent, which can reveal the design features of the smartphone, such as the brand logo. In order not to affect the photographing function of the smartphone, at least one lens opening 21 is further opened on the protective back plate 20 so that the lens of the smartphone (or the larger lens module 2 ) can be exposed without being affected by the protective back plate 20 .

See Figures 2 and 3 for a description of the rotating support structure. FIG. 2 is a diagram showing the operation of the second rotating support structure 32 of the mobile phone protective case 1 , and FIG. 3 is a perspective view of the inner side of the second rotating support structure 32 . In the first rotary support structure 31 , the second rotary support structure 32 , the third rotary support structure 33 and the fourth rotary support structure 34 , each rotary support structure includes a straight line segment 30 a and a curved segment 30 b connected thereto. Take the second rotating support structure 32 as an example to illustrate. The end of the straight section 30a is pivotally connected to a pivot hole 14 on the short side of the elastic protective frame 10 (represented by a dotted frame), so that the end of the curved section 30b can be located at a certain point outside the protective back panel 20 from the position of the elastic protective frame 10, Rotate along the pivot hole 14 . According to the present invention, the rotation angle α may be between 0 degrees and 110 degrees.

In order to achieve the above purpose, the rotating support structure is also designed with the following details. Taking the second rotating support structure 32 as an example, an attaching surface 321 is formed on the inner side of the second rotating supporting structure 32 , and a pivot shaft 322 is formed at the end of the attaching surface 321 adjacent to the straight section 30 a but connected to the pivot hole 14 . A blocking plate 323 is formed inward from the lower end of the attaching surface 321 , and one end of the blocking plate 323 forms a lateral blocking end 3231 . The functions of the blocking plate 323 and the lateral blocking end 3231 will be described below. As shown in FIG. 3 , the attachment surface 321 is a plane at the straight line segment 30 a , and a curved surface at the curved segment 30 b .

Since the rotating support structure needs to be attached to the elastic protection frame 10 to rotate, it can be fixed when it rotates to the limit, and is fixed on the elastic protection frame 10 when it is not rotated. Therefore, the elastic protection frame 10 cooperates with the rotating support structures and can be fixed at each corner. A multi-layer stepped structure 15 (indicated by a double-dot dashed box) is formed from the lead circle to the rear of the pivot hole 14 in accordance with the inner shape of the rotating support structure. Take the second rotating support structure 32 as an example to illustrate. When the second rotating support structure 32 is located on the elastic protection frame 10 (multi-layer stepped structure 15 ) , the second rotating support structure 32 does not rotate at this time. A first step 151 of the multi-layer stepped structure 15 can be in close contact with the attaching surface 321. At this time, the vertical wall surface of the first step 151 is in contact with the blocking plate 323 to restrict the rotation of the second rotating support structure 32. A first step of the multi-layer stepped structure 15 The vertical wall surfaces of the second steps 152 can abut against the side walls of the second rotating support structure 32 .

When the second rotating support structure 32 is located on the multi-layer stepped structure 15, in order to make the bonding between the two more stable, a clamping bump 324 is formed on the attaching surface 321 adjacent to the end of the curved section 30b, and the first step 151 corresponds to the clamping point 324. A clamping depression 16 is formed at the bump-setting point 324, so that when the first step 151 is in close contact with the attaching surface 321, the clamping-bonding point 324 falls into the clamping depression 16, so that the second rotating support structure 32 is temporarily connected to the attaching surface 321. The elastic protection frame 10 is fixedly connected.

When the end of the curved section 30b of the rotating support structure rotates from the multi-layer stepped structure 15 to a certain point outside the protective backplane 20 along the pivot hole 14, the rotating support structure can stay at any position therebetween. However, the limit of rotation of the end of the curved section 30b is also the position where the mobile phone protective case 1 exerts another function, and the rotating support structure needs to be clamped and cannot be rotated further. For this purpose, the elastic protection frame 10 forms a protrusion 17 behind the pivot hole 14 of each rotating support structure. The first rotating support structure 31 is taken as an example for description. When the first rotating support structure 31 rotates to the limit along its pivot hole, its lateral stop end 3231 will abut against the protrusion 17, and the first rotating support structure 31 will no longer rotate.

Since the preset position of the rotating support structure when it is not rotating is on the multi-layer stepped structure 15 , it is also located at the corner of the elastic protection frame 10 . In order to enhance the anti-impact capability of the place and avoid damage to the smartphone casing caused by stress concentration, the rotating support structure is preferably made of a hard material. According to the present invention, the material of the rotating support structures can also be polycarbonate. In addition, since the rotating support structure can be used as a temporary plane support for the mobile phone protective case 1 and its internal mobile phone (which will be described below), the rotating support structure must have a certain frictional force. Therefore, as shown in FIG. 2 , a plurality of anti-slip bars are formed on the outer side of the rotating support structure. It is worth noting that in terms of structure, in order to reduce the cost of molds in the manufacture of the mobile phone protective case 1, the rotating support structures may not be completely different. According to the present invention, the elastic protective frame 10 is located in The two rotating support structures at adjacent positions are symmetrical to each other, and the two rotating support structures at opposite positions of the elastic protection frame 10 are completely identical. That is to say, the first rotary support structure 31 and the second rotary support structure 32 are symmetrically designed, the third rotary support structure 33 and the fourth rotary support structure 34 are also symmetrically designed; the first rotary support structure 31 and the fourth rotary support structure are also symmetrically designed. 34 are identical, and the second rotational support structure 32 is also identical to the third rotational support structure 33 .

For the usage of the mobile phone protective case 1, please refer to Figure 3 and Figure 4. In FIG. 3 , the first rotating support structure 31 (which is blocked by the third rotating support structure 33 and cannot be seen) and the third rotating support structure 33 are rotated outward to the limit, and the mobile phone protective case 1 together with the smartphone inside it (not shown) yaw, the side of the elastic protection frame 10, the first rotating support structure 31 and the third rotating support structure 33 are placed on the same plane, and the smart phone is also fixed at an angle. At this time, the user can watch the video through the smartphone for a long time. In FIG. 4 , the first rotating support structure 31 (which is blocked by the second rotating support structure 32 and cannot be seen) and the second rotating support structure 32 are rotated outward, and it is not necessary to reach their limit. Using the first rotating support structure 31 and the second rotating support structure 32 to directly hang a smartphone (not shown) on a partition 3, the smartphone can be used for fixed-point shooting, such as for live broadcast. As can be seen from the above description, if the mobile phone protective case 1 of the present invention is not used, in order to achieve the aforementioned purpose, the general mobile phone protective case needs to be externally attached with support rods or hooks, which is inconvenient to use.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of this new model shall be determined by the scope of the appended patent application.
