Specific embodiments of a mobile terminal protective case are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, there are schematic perspective views of a mobile terminal protection case 10 (hereinafter, referred to as a protection case 10) according to an embodiment of the present application. The protective case 10 includes a main case 12 and a bracket 14 mounted to the main case 12. The main housing 12 may be made of silica gel, PC, TPU, or a combination thereof. The main housing 12 includes a bottom wall 16 having opposing inner 18 and outer 20 bottom wall surfaces, the main housing 12 having a receiving position on one side of the inner bottom wall surface 18 for receiving a mobile terminal. The mobile terminal may be various portable electronic devices such as a mobile phone or a tablet computer. The present application takes a mobile terminal as an example for explanation.

In some embodiments, the main housing 12 further includes at least one sidewall extending from the bottom wall 16, wherein the sidewall and the bottom wall 16 together form a receiving space for receiving the mobile terminal. In the illustrated embodiment, the main housing 12 includes four side walls 22, and the four side walls 22 and the bottom wall 16 together form a receiving space 24 for receiving a mobile terminal (e.g., a cellular phone).

The stand 14 is capable of rotating relative to the main housing 12 between a plurality of positions including a folded position and at least one unfolded position. Fig. 1 illustrates the cradle 14 in a folded position, wherein the cradle 14 is positioned against the outer surface 20 of the bottom wall, preventing the cradle 14 from interfering with some mobile phone operations (e.g., placing the phone flat on a table, placing the phone in a pocket of clothing, or placing the phone on a wireless charger, etc.).

Figure 3 shows the stand 14 in the deployed position as a handset support. The stand 14 is angled with respect to the bottom wall 16 so that the phone can be supported at an angle in a plane.

Figure 4 shows the deployed position of the stand 14 as a tab. At this point, the bracket 14 is rotated 180 degrees to be coplanar or parallel with the bottom wall 16.

It should be understood that the two deployed positions are illustrated above, and that in other embodiments, the stand 14 can be configured to have other deployed positions, forming other angles with the bottom wall 16.

As shown in fig. 5, the bracket 14 is mounted to one of the side walls 22 of the main housing 12. In the embodiment shown, the bracket 14 is fixedly mounted by means of rivets 26 on the outside of a long side wall provided with a recessed mounting portion 27 for riveting of the bracket 14. In other embodiments, the bracket 14 may also be mounted to the bottom wall 16.

Referring also to FIG. 6, in the illustrated embodiment, the bracket 14 includes a shaft 28, a fixed member 30 rotatably coupled to the shaft 28, and a ring member 32 non-rotatably coupled to the shaft 28. The fixing member 30 is fixedly mounted to the mounting portion 27 of the side wall 22 by means of the rivet 26, thereby mounting the bracket 14 to the main housing 12. The thickness of the fixing member 30 corresponds to the depth of the recess of the mounting portion 27. The ring member 32 is rotatable relative to the fixed member 30, and thus relative to the main housing 12, between the aforementioned folded position and at least one unfolded position using the shaft 28. In different positions, the ring 32 performs the function of a handset cradle or the function of a pull ring. The fixing member 30 is generally made of a metal material with high strength.

The side of the fixing member 30 forms a pivot portion 34, and the pivot portion 34 is rotatably sleeved on the rotating shaft 28, specifically, the middle section of the rotating shaft 28. Referring to fig. 7, in the embodiment shown, the pivoting portion 34 is formed by winding the side of the fixing element 30 into a tubular shape, wherein after the tubular pivoting portion 34 is formed by winding, the end 35 of the side of the fixing element 30 is disconnected from the inner wall surface 36 of the pivoting portion 34. The disconnected state refers to a state of loose engagement, and the tip 35 may or may not be in contact with the inner wall surface 36.

Referring to fig. 8 and 9, a rotation-stopping return mechanism formed between the pivot portion 34 and the shaft 28 is shown. The outer peripheral surface of the rotating shaft portion of the rotating shaft 28 located in the pivot portion 34 has a first plane 38 and a first arc surface 40 connected to the first plane 38. The inner wall surface 36 of the pivot portion 34 is provided with a second flat surface 42 and a second arc surface 44. When the ring 32 is in the folded position, the first plane 38 of the shaft 28 abuts against the second plane 42 of the pivot portion 34, and the first arc surface 40 of the shaft 28 abuts against the second arc surface 44 of the pivot portion 34. When the ring 32 is opened without external force, the shaft 28 and the pivot portion 34 are fixed relatively to each other to keep the ring 32 in the folded position. When the user manually operates the ring 32 to rotate the ring 32 away from the folded position (i.e., to the unfolded position), the rotating shaft portion inside the pivoting portion 34 rotates to press the inner wall surface 36 of the pivoting portion 34, so as to open the end 35 of the side of the fixing member 30 and expand the inner diameter of the pivoting portion 34 to allow the rotation between the pivoting portion 34 and the rotating shaft 28. When the user rotates the ring 32 from the unfolded position to the folded position, the user only needs to manually rotate the ring 32 in the initial stage, and then the portion of the fixing member 30 near the end elastically presses the rotating shaft, so that the ring 32 automatically returns to the folded position and is kept in the folded position.

Referring to fig. 6, 10 and 11, a connecting portion 46 is disposed at a position of the ring member 32 close to the fixing member 30, and the connecting portion 46 is fixedly connected to the rotating shaft 28, so that the connecting portion 46 and the rotating shaft 28 do not rotate relatively. In the illustrated embodiment, the connecting portion 46 includes at least one connecting tube 48, the connecting tube 48 being disposed around the shaft 28; a damping material is disposed between the connecting tube 48 and the shaft 28 to increase friction between the connecting tube 48 and the shaft 28, so that the connecting tube 48 and the shaft 28 are fixed and cannot rotate relative to each other, and therefore the ring member 32 cannot rotate relative to the shaft 28. In the illustrated embodiment, the connecting portion 46 has two connecting tubes 48 respectively disposed at two sides of the fixing member 30 and sleeved on two ends of the rotating shaft 28; the damping material is a damping tube 50, and a damping tube 50 is sandwiched between each connecting tube 48 and the rotating shaft 28.

Referring again to fig. 5 and 6, the ring 32 has opposite annular inner 52 (see fig. 4) and outer 54 surfaces. In the folded position, the annular inner surface 52 of the ring 32 abuts the bottom wall outer surface 20 of the main housing 12. The bottom wall outer surface 20 is provided with a receiving groove 56 that matches the shape of the ring 32. In the folded position, the ring 32 is received in the receiving groove 56 and the outer annular surface 54 of the ring 32 is flush with the outer bottom wall surface 20 of the main housing 12. The bottom wall outer surface 20 is further provided with a depression 58 on the outside of the receiving groove 56 for a snap-in position. The recess 58 communicates with the receiving slot 56 to facilitate the opening of the ring 32 from the folded position by the user. In the illustrated embodiment, the recess 58 is provided in the periphery of the receiving groove 56 on a side remote from the mounting portion 27 on the main housing side wall 22.

The ring 32 is magnetically impermeable and is typically made of an alloy material, such as an aluminum alloy, a zinc alloy, or the like. At least one magnetic conducting member 60 is disposed on the annular outer surface 54. The magnetic conduction members 60 are distributed along the circumferential direction of the annular outer surface 54 and form notches 62 penetrating in the radial direction in the circumferential direction. In the illustrated embodiment, two magnetically permeable members 60 are provided. Each magnetic conducting member 60 is in the shape of a curved strip. More specifically, the magnetic conductive member 60 may be an iron plate. Having two opposite circumferential ends 64 in the circumferential direction. Adjacent circumferential ends 64 of the two magnetic conducting members 60 are spaced apart a distance to form two notches 62.

The magnetic conductive member 60 is disposed on the annular outer surface 54 to fix the mobile terminal mounted in the protective case 10 to other objects by magnetic attraction. One of the application scenarios is that the magnetic attraction is fixed on a wireless charger for wireless charging. Generally, a transmitting coil of a charger and a magnet located at the periphery of the transmitting coil are disposed on a wireless charger, and a receiving coil for wireless charging is disposed inside a mobile terminal such as a mobile phone. The position of the magnetically permeable member 60 on the ring member 32 is such that when said ring member 32 is in the folded position, the magnetically permeable member 60 is located radially on the periphery of the receiver coil of the handset mounted in the protective case 10. When the wireless charger is charged wirelessly, the receiving coil of the mobile phone is opposite to the transmitting coil of the wireless charger, the magnetic conduction piece 60 is opposite to the magnet of the wireless charger, and the mobile phone is positioned on the wireless charger under the action of magnetic attraction between the magnetic conduction piece and the magnet of the wireless charger. The notch 62 is arranged, so that the magnetic conduction piece 60 can effectively reduce the turbulent flow induction and heating in the wireless charging process on the premise of finishing the function of magnetic positioning, and the influence of the magnetic conduction piece 60 on wireless charging is avoided or reduced.

In the illustrated embodiment, the annular outer surface 54 is provided with a mounting slot 66, and the magnetic conductive member 60 is mounted in the mounting slot 66. The outer surface of the magnetic conducting member 60 does not extend beyond the annular outer surface 54 and may be lower than the annular outer surface 54 or flush with the annular outer surface. The magnetic conductive member 60 is, for example, adhesively fixed in the mounting groove 66. The magnetic conduction member 60 is installed in the installation groove 66, and the outer surface of the magnetic conduction member 60 does not exceed the annular outer surface 54, so that the distance between the mobile phone receiving coil and the wireless charger transmitting coil cannot be increased due to the arrangement of the magnetic conduction member 60, and the situation that the charging efficiency is reduced due to the increase of the distance is avoided.

Although the illustrated embodiment shows two magnetic conducting members 60, in other embodiments only one magnetic conducting member in the form of a strip may be provided on the annular outer surface 54, the gap being formed between the two circumferential ends of the single strip. In some embodiments, more than two magnetic conduction members may be further provided, and the gap penetrating in the radial direction is formed between adjacent circumferential ends of any two adjacent magnetic conduction members.

In the above embodiment, the magnetic conductive member 60 is disposed on the annular outer surface 54 of the annular member 32. In other embodiments, the magnetic permeable member 60 may also be disposed on the annular inner surface 52 of the annular portion. The distance between the magnetic conductive member 60 on the annular inner surface 52 and the wireless charger magnet is greater than the distance between the magnetic conductive member 60 on the annular outer surface 54 and the wireless charger magnet, so that the magnetic conductive member 60 on the annular outer surface 54 is better than the magnetic conductive member on the annular inner surface 52. In addition, the magnetic conduction member 60 is exposed on the annular outer surface 54, so that the magnetic conduction member can be matched with the annular member 32 to increase the layering effect and achieve better aesthetic property.

To sum up, the application discloses a mobile terminal protective housing with function is inhaled to magnetism, and this mobile terminal protective housing has rotatable support, and the support can realize multiple different functions in different positions. The support comprises an annular part, wherein the annular part is provided with at least one magnetic conduction part, and the at least one magnetic conduction part is distributed along the circumferential direction of the annular part and forms a notch which penetrates through the annular part in the radial direction in the circumferential direction. The setting of above-mentioned breach for magnetic conduction spare itself can not form closed return circuit, thereby can effectively reduce the vortex response and generate heat among the wireless charging process under the function prerequisite of accomplishing the magnetism location, thereby avoids or reduces the influence that magnetic conduction spare was to wireless charging. In some embodiments, the magnetic conduction member is installed in the installation groove of the annular outer surface of the annular member, and the outer surface of the magnetic conduction member does not exceed the annular outer surface of the annular member, so that the distance between the mobile phone receiving coil and the wireless charger transmitting coil cannot be increased due to the arrangement of the magnetic conduction member, and the situation that the charging efficiency is reduced due to the increase of the distance is avoided.
