[0053] See attached Figure 1 -Attached Figure 8A bracket-type mobile phone case that is easy to dissipate heat is characterized in that it includes a frame 1 and a back plate 2; the frame 1 is provided with a receiving cavity 10 for placing and fixing a mobile phone P, and the back side of the receiving cavity 10 is provided with a heat dissipation port 100 that exposes the back of the mobile phone P; the back plate 2 is connected to the frame 1, and the heat dissipation port 100 can be opened or closed, and after the heat dissipation port 100 is opened, the back plate 2 can support the frame 1 and be used as a bracket.

[0054] Specifically, under normal circumstances, when the back plate 2 closes the heat dissipation port 100, the mobile phone P is enclosed therein, so as to be used as a mobile phone case and protect the mobile phone P therein; when the back plate 2 is moved to open the heat dissipation port 100, the expanded back plate 2 stops and supports the frame 1 to be used as a bracket, so that the mobile phone P can be placed sideways or upright, and at the same time, the back of the mobile phone P can also discharge heat through the heat dissipation port 100.

[0055] In summary, the utility model designs a accommodating cavity 10 in the frame 1 for fixing the mobile phone P, and the heat dissipation port 100 on the back side of the accommodating cavity 10 is used for dissipating heat from the back of the mobile phone P; the back plate 2 is designed to open and close the heat dissipation port 100 to enclose the mobile phone P or support the frame 1, so that the combination of the frame 1 and the back plate 2 can be used as a conventional mobile phone case and as a bracket; compared with the prior art, the mobile phone case has a simple structure, uses fewer accessories, is light in overall weight, is highly portable, and has a heat dissipation function when used as a bracket, and has high usability.

[0056] See attached Figure 1 -Attached Figure 8 In order to make the back plate 2 stably stop and conveniently adjust the expansion angle of the back plate 2, the utility model also includes a damping part 3, and the back plate 2 is rotatably connected to the frame 1 through the damping part 3 to open or close the heat dissipation port 100. After the back plate 2 opens the heat dissipation port 100, the expansion angle between the back plate 2 and the frame 1 can be adjusted through the damping part 3.

[0057] Specifically, under normal circumstances, the back panel 2 closes the heat dissipation port 100 to enclose and protect the mobile phone P; when the back panel 2 is rotated to open the heat dissipation port 100, the expanded back panel 2 supports the frame 1, and the user can adjust the relative expansion angle between the back panel 2 and the frame 1 through the damping part 3, thereby adjusting the display angle of the mobile phone P; since the damping part 3 has an obstructing effect, the back panel 2 can stably stay in the current position when not subject to external force, so that the back panel 2 can stably close the heat dissipation port 100 or support the frame 1.

[0058] It should be noted that an additional support rod (not shown) may be provided between the main frame 1 and the back plate 2 to form a triangular support structure between the main frame 1, the back plate 2 and the support rod, thereby improving the support stability of the expanded back plate 2; however, considering that the support rod will increase the weight, and the back plate 2 needs a certain placement space after folding, which is inconvenient to use, the damping part 3 is preferably used in the present invention; and the structure of the damping part 3 is diverse. For ease of understanding, the present invention lists the following embodiments:

[0059] Embodiment 1

[0060] As attached Figure 5 -Attached Fig.10 As shown, the damping part 3 includes a rotating shaft 31 and a sleeve 32. A rotating groove 11 is provided on one side of the frame 1. The rotating shaft 31 is embedded in the rotating groove 11. The sleeve 32 is installed on the back plate 2, and a shaft hole 320 is provided on the sleeve 32. The shaft hole 320 is sleeved on the rotating shaft 31 and has an interference fit with the rotating shaft 31.

[0061] Specifically, when in use, the back panel 2 is moved to drive the sleeve 32 to rotate around the shaft 31 to open the heat dissipation port 100. Since there is a damping effect between the shaft hole 320 and the shaft 31, the back panel 2 stops when no force is applied, and forms a triangular structure with the frame 1 and the placement plane, thereby stably supporting the mobile phone P. The user can also adjust the display angle of the mobile phone P by controlling the rotation amplitude of the back panel 2 around the shaft 31. After use, the back panel 2 is moved to rotate back to its original position around the shaft 31 to reclose the heat dissipation port 100.

[0062] Furthermore, a notch 321 is provided on the shaft sleeve 32, and the shaft 31 can enter and exit the shaft hole 320 through the notch 321, so that the back panel 2 and the frame 1 can be detachably connected. This design is convenient for workers to assemble the back panel 2 to the frame 1, thereby improving the convenience of assembly. At the same time, it is also convenient for users to replace different types of back panels 2 such as transparent, frosted, etc. according to their needs, thereby improving the fun.

[0063] In addition, the damping part 3 can also remove the sleeve 32 and install the rotating shaft 31 on the back plate 2, and then design a rotating hole that is interference fit with the rotating shaft 31 in the rotating groove 11, so that the back plate 2 and the frame 1 are rotatably connected and damped; wherein, if the damping part 3 adopts the matching structure of the rotating shaft 31 and the sleeve 32, the frame 1 can adopt a soft shell or a hard shell, and if the damping part 3 adopts the matching structure of the rotating shaft 31 and the rotating hole, the frame 1 generally adopts a soft shell to facilitate the rotating shaft 31 to be clamped into the rotating hole.

[0064] Embodiment 2

[0065] As attached Fig.12 -Attached Fig.13As shown, the damping part 3 is a plastic sheet 33, one end of the plastic sheet 33 is mounted on the frame 1, and the other end is fixed to the back plate 2; the plastic sheet 33 is deformed after being subjected to force and has no rebound ability.

[0066] Specifically, when in use, the back panel 2 is moved to open the heat dissipation port 100. During this process, the plastic sheet 33 is deformed by force, and the deformed plastic sheet 33 has a damping effect, so that the back panel 2 can stay in the current position when no force is applied, and form a triangular structure with the frame 1 and the placement plane, thereby stably supporting the mobile phone P; after use, the back panel 2 is moved to drive the plastic sheet 33 to return to its original state until the back panel 2 closes the heat dissipation port 100 again.

[0067] Among them, since the plastic sheet 33 can be adaptively deformed according to the magnitude of the force it is subjected to, and can only be deformed again when subjected to a specific force, it not only has a damping feeling, but also makes it convenient for users to control the relative expansion angle between the back panel 2 and the frame 1, thereby adjusting the display angle of the mobile phone P.

[0068] Furthermore, the plastic sheet 33 can be made of metal materials with plasticity, such as aluminum alloy, iron, copper, etc., or made of other plastics with plasticity, which are not listed one by one in the utility model. For the sake of ease of understanding, the plastic sheet 33 is taken as an example of being made of aluminum alloy material in the utility model.

[0069] Among them, aluminum alloy has good bendability and fatigue resistance, strong plasticity, and can stably maintain the current shape after being bent and deformed, so that a certain angle of relative expansion is maintained between the back panel 2 and the frame 1, and it can be bent repeatedly for many times, with a long service life.

[0070] It should be noted that, in addition to the structure in the above embodiment, the damping part 3 may also adopt other damping structures such as a damping hinge. Due to the variety of types, this is not limited in the present invention.

[0071] See attached Figure 5 -Attached Figure 8 and attached Fig.11 -Attached Fig.13 In actual use, the damping part 3 can make the back plate 2 stop after closing the heat dissipation opening 100. However, when the mobile phone P falls and vibrates violently, the back plate 2 may still vibrate and open the heat dissipation opening 100. To solve this problem, the utility model further includes a fastening part 4. When the back plate 2 closes the heat dissipation opening 100, the fastening part 4 can drive the back plate 2 and the frame 1 to be relatively fixed, so that the back plate 2 can stop more stably at the heat dissipation opening 100. The damping part 3 has various structures. For easy understanding, the utility model lists the following embodiments:

[0072] Embodiment 1

[0073] As attached Figure 3 -Attached Figure 7 As shown, the fastening portion 4 includes a magnetic strip 41 and a magnetic block 42. The magnetic strip 41 is installed on the side wall of the back panel 2 and is offset from the damping portion 3. The magnetic block 42 is installed on the frame 1. When the back panel 2 closes the heat dissipation port 100, the magnetic block 42 absorbs the magnetic strip 41, thereby making the back panel 2 stably stagnant; when the back panel 2 is pried to open the heat dissipation port 100, the magnetic strip 41 is offset from the magnetic block 42.

[0074] Embodiment 2

[0075] As attached Figure 8 and attached Fig.13 As shown, the fastening portion 4 includes a magnetic ring 43, which is installed on the inner surface of the back panel 2. When the back panel 2 closes the heat dissipation port 100, the magnetic ring 43 is attracted to the magnetic circle (not shown) inside the mobile phone P, thereby making the back panel 2 stably stagnant; when the back panel 2 is pried open to open the heat dissipation port 100, the magnetic ring 43 is separated from the magnetic circle.

[0076] In this embodiment, the magnetic ring 43 can be made of a magnet or a magnetic metal; if the magnetic ring 43 is made of a magnet, it can more firmly absorb the magnetic circle to improve stability; if the magnetic ring 43 is made of a magnetic metal, the back plate 2 can absorb both the magnetic circle in the mobile phone P and the magnet in the external wireless charger / wireless power bank (not shown) to improve versatility; manufacturers can choose settings according to actual needs.

[0077] Embodiment 3

[0078] As attached Fig.15 -Attached Fig.19 As shown, the fastening portion 4 includes a buckle position 44 arranged on the back plate 2 and a buckle 45 arranged on the frame 1, and when the back plate 2 closes the heat dissipation port 100, the buckle 45 engages with the buckle position 44 to complete the fixation; this fixed structure design has a low production cost and a more stable connection.

[0079] It should be noted that the above embodiments can be set separately or in combination, and in addition to the structure in the above embodiments, the fastening part 4 can also adopt an adhesive structure of Velcro (not shown) set on the back panel 2 and the frame 1, etc. Due to the variety of types, this is not limited in the utility model.

[0080] Attached Fig.15 -Attached Fig.16 Considering that the back panel 2 and the frame 1 are tightly fitted when the heat dissipation port 100 is closed, which is inconvenient for users to operate, in order to facilitate users to pry open the back panel 2, in the utility model, a movable port 12 is provided on the frame 1, and a shift block 21 matching the movable port 12 is provided on the back panel 2, and the shift block 21 can be detached from or clamped into the movable port 12.

[0081] Specifically, when the back panel 2 closes the heat dissipation port 100, the shift block 21 is engaged with the movable port 12 to hide it, thereby ensuring the overall aesthetics; when the back panel 2 needs to be rotated to open the heat dissipation port 100, the fingernail is placed in the movable port 12 and the shift block 21 is moved out of the movable port 12; and for the convenience of operation, a certain avoidance space can also be set at the movable port 12 for finger movement.

[0082] The shifting block 21 can be arranged at a specific position on the side of the back plate 2 , and the movable opening 12 is arranged to match the shifting block 21 .

[0083] See attached Figure 3 , Attachment Figure 8 and attached Fig. 9 A socket 13 is provided on the frame 1 corresponding to the charging part P1 of the mobile phone P, and the movable port 12 is designed at the socket 13 and connects the socket 13 and the heat dissipation port 100 .

[0084] Specifically, the above design allows the socket 13 to be used as an escape space for the user to pry the shift block 21 located in the movable port 12, thereby improving the convenience of operation. In addition, no additional grooves are required on the frame 1, thereby reducing the manufacturing cost and improving the overall aesthetics.

[0085] See attached Figure 1 -Attached Figure 3 The frame 1 is provided with a limit block 14 at the heat dissipation port 100 , and the mobile phone P is placed in the accommodating cavity 10 and abuts against the limit block 14 ; the probability of the mobile phone P falling out of the heat dissipation port 100 is reduced, so that the frame 1 can fix the mobile phone P more stably.

[0086] The limiting block 14 may be arranged in a ring shape so as to simultaneously support the back of the mobile phone P at multiple positions, so as to further improve the placement stability of the mobile phone P.

[0087] It should also be noted that the size of the heat dissipation opening 100 can be as shown in the attached figure. Figure 1 -Attached Fig.13 The fully open design can also be used as shown in the attached Fig.14 The semi-open design is not limited in the present invention, and the size of the back plate 2 is adapted to the setting of the heat dissipation port 100; in addition, regarding the installation position of the back plate 2 and the damping part 3, it can be set on any left or right side of the frame 1, or on any upper or lower side of the frame 1 (not shown in the figure), so that the mobile phone P can be placed vertically or longitudinally. The manufacturer can choose the setting according to user needs, and the present invention does not limit this.

[0088] See attached Fig.15 A rope hole 15 is provided on the side wall of the frame body 1, and the rope hole 15 can be used to insert a hanging rope (not shown in the figure) to facilitate carrying the mobile phone P, thereby further improving the portability.

[0089] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
