It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] First embodiment:

[0038] A communication device protective case with charging function, such as Figure 1-Figure 3 , Figure 6 , Figure 7 and Fig.10As shown, it includes a protective shell 1 and a communication device 2.

The two partitions 6 divide the space in the second outer cylinder 4 into an upper chamber 17, a middle chamber 18 and a lower chamber 19, and a winding roller 10 is rotatably connected in the upper chamber 17; it also includes a rope 8 and a protective film 9, one end of the rope 8 passing through the first outer cylinder 3 is drivingly connected to the rope collection mechanism 5, one end of the protective film 9 passing through the upper chamber 17 is wound around the winding roller 10, and the other end of the rope 8 is fixedly connected to the other end of the protective film 9;

[0039] A wind supply mechanism 11 is provided in the lower chamber 19, a first gear 12 is rotatably provided on the inner top wall of the middle chamber 18, the winding roller 10 is coaxially fixedly connected to the first gear 12, a second gear 13 is rotatably provided on the inner bottom wall of the middle chamber 18, the wind supply mechanism 11 is drivingly connected to the second gear 13, a rotating rod 14 is rotatably provided in the middle chamber 18, a fan gear 15 is coaxially fixedly connected to the rotating rod 14, the central angle of the fan gear 15 is 340 degrees, the second gear 13 is meshingly connected with the fan gear 15, a driving cylinder 20 is slidably fitted on the rotating rod 14, a key block is provided on the rotating rod 14, a key slot is provided on the driving cylinder 20, the key block and the key slot are slidably fitted, so that the driving cylinder 20 can slide along the rotating rod 14, and when the rotating rod 14 rotates, the driving cylinder 20 will rotate synchronously with the rotating rod 14, a driving tooth 21 is provided on the inner wall of the driving cylinder 20, and the first gear 12 is meshingly connected with the driving tooth 21.

[0040] When the air supply mechanism 11 drives the first gear 12 to rotate forward, the fan gear 15 is driven to rotate with the rotating rod 14, the key block presses against the key slot to rotate the driving cylinder 20, the driving tooth 21 presses against the first gear 12 to rotate, and the winding roller 10 rotates to put the protective film 9 into the second outer cylinder 4.

[0041] like Figure 3 and Fig. 9 As shown, the rope collecting mechanism 5 includes a center rod 23 coaxially fixedly arranged in the first outer cylinder 3, an inner cylinder 24 is coaxially rotatably arranged in the first outer cylinder 3, the center rod 23 is located inside the inner cylinder 24, a spiral spring 25 is installed between the center rod 23 and the inner cylinder 24, a winding ring 26 is coaxially fixedly connected to the inner cylinder 24, and the rope 8 is wound around the winding ring 26.

[0042] When the protective film 9 is received in the second outer tube 4 , the protective film 9 pulls the rope 8 out of the first outer tube 3 , and at the same time the inner tube 24 rotates to allow the spiral spring 25 to store force.

[0043] like Figure 1, Figure 4 and Figure 7 As shown, the top and bottom of the protective film 9 are provided with a first edge strip 27, and the protective shell 1 is fixedly connected with a guide rail 28. The first edge strip 27 is a flexible plastic strip. The protective film 9 moves synchronously with the first edge strip 27. The protective film 9 and the first edge strip 27 can be received in the second outer cylinder 4, and the first edge strip 27 and the guide rail 28 are slidably matched; when the protective film 9 is pulled out of the second outer cylinder 4 or received in the second outer cylinder 4, the first edge strip 27 will slide in the guide rail 28; after the protective film 9 is pulled out of the second outer cylinder 4, it can protect the screen of the communication device 2; when a foreign object impacts the front of the device, the protective film 9 can buffer the impact force, and the top and bottom of the protective film 9 can be positioned by using the setting of the guide rail 28 to avoid the protective film 9 being subjected to a large impact. The top and bottom of the protective film 9 move toward the middle to prevent the protective film 9 from deforming too much when the protective film 9 is subjected to a large impact, thereby causing the screen of the communication device 2 to be impacted and broken.

[0044] like Figure 6 and Fig.10 As shown, a torsion spring 16 is sleeved on the rotating rod 14 between the inner bottom wall of the middle chamber 18 and the sector gear 15, and two ends of the torsion spring 16 are fixedly connected to the inner bottom wall of the middle chamber 18 and the sector gear 15 respectively.

[0045] like Figure 1-Figure 3 and Figure 8 As shown, the air supply mechanism 11 includes a rotating shaft 31 rotatably arranged in the lower chamber 19, and a motor 32 is installed at the bottom of the second outer tube 4. The motor 32 is a servo motor and can rotate forward and reverse. The output end of the motor 32 is coaxially fixedly connected to the bottom end of the rotating shaft 31, and the top end of the rotating shaft 31 penetrates into the middle chamber 18 and is coaxially fixedly connected to the second gear 13. Fan blades 33 are provided on the rotating shaft 31 in the lower chamber 19, and an air inlet 34 and an air outlet 35 are provided on the side wall of the second outer tube 4. The air inlet 34 and the air outlet 35 are both connected to the interior of the lower chamber 19.

[0046] An elastic bag 36 is provided on the protective shell 1, and the air outlet 35 is fluidly connected to the elastic bag 36 through the air pipeline 37. A one-way valve 38 is provided on the air pipeline 37, and the one-way valve 38 can prevent the gas in the elastic bag 36 from flowing back into the air pipeline 37. A pressure relief valve 39 is provided on the elastic bag 36, and the air outlet direction of the pressure relief valve 39 is set toward the back of the communication device 2.

[0047] When the motor 32 drives the rotating shaft 31 to rotate, the fan blades 33 rotate, and the external air is drawn into the lower chamber 19 through the air inlet 34, and then the gas is successively input into the elastic bag 36 through the air outlet 35 and the air supply pipe 37. When the air pressure in the elastic bag 36 reaches the set value, the pressure relief valve 39 opens and sprays air to the back of the communication device 2, thereby improving the heat dissipation effect of the communication device 2.

[0048] like Figure 1 and Figure 3 As shown, a charging device 59 is installed in the protective shell 1, and a charging connector is provided on the charging device 59. When the communication device 2 is loaded into the protective shell 1, the charging connector is inserted into the charging interface of the communication device 2. A control unit 62 is provided on the protective shell 1, and the motor 32 and the charging device 59 are both electrically connected to the control unit 62. In this embodiment, the control unit 62 is a controller, and the controller is a prior art. The control unit 62 can control the charging device 59 to charge the communication device 2, and the control unit 62 can control the start and stop of the motor 32.

[0049] like Figure 1-Figure 4 As shown, a closing cover 53 is provided on the top of the protective shell 1, an insertion rod 54 is provided on the bottom of the closing cover 53, a positioning groove 55 is provided on the insertion rod 54, a slot is provided on the top of the protective shell 1, the bottom end of the insertion rod 54 is inserted into the slot, a locking rod 56 is inserted on the protective shell 1, an inclined surface is provided on the end of the locking rod 56 inserted into the slot, the end of the locking rod 56 inserted into the slot is engaged with the positioning groove 55, a pull handle 57 is provided on the other end of the locking rod 56, an elastic block 58 is provided between the protective shell 1 and the pull handle 57, and a soft pad 60 is provided at the bottom of the closing cover 53.

[0050] The top of the protective shell 1 is provided with an opening, and the communication device 2 is inserted into the protective shell 1 through the opening, and the insertion rod 54 is inserted into the slot, and the closing cover 53 is pressed on the top of the communication device 2. During the insertion of the insertion rod 54 into the slot, since the locking rod 56 is provided with an inclined surface, when the bottom end of the insertion rod 54 hits the inclined surface, the locking rod 56 moves away from the protective shell 1 with the handle 57, and the locking rod 56 does not affect the insertion of the insertion rod 54 into the slot; when the insertion rod 54 is fully inserted into the slot, the locking rod 56 is aligned with the positioning groove 55, and the elastic block 58 releases the force to pull the handle 57 to reset, and the locking rod 56 is reset and inserted into the positioning groove 55, thereby positioning the closing cover 53, thereby realizing the positioning of the communication device 2 and completing the installation of the communication device 2; it should be noted that during the insertion of the insertion rod 54 into the slot, the closing cover 53 moves downward so that the bottom of the cushion 60 hits the top of the communication device 2, and the cushion 60 is deformed after being squeezed, thereby increasing the contact area with the communication device 2, which can improve the stability of the installation of the communication device 2.

[0051] When the communication device 2 needs to be removed, the handle 57 is pulled to align the locking rod 56 with the positioning groove 55, thereby releasing the limit on the closing cover 53, and the cushion 60 recovers and pushes against the closing cover 53 to move upward. The locking rod 56 and the positioning groove 55 are no longer aligned, and then the protective shell 1 is separated from the closing cover 53, so that the communication device 2 in the protective shell 1 is taken out, and the removal of the communication device 2 is completed.

[0052] When the device in this embodiment is in use, when communication is required using the communication device 2, the control unit 62 controls the motor 32 to drive the rotating shaft 31 to rotate in the forward direction, the second gear 13 drives the fan gear 15 to rotate, the driving cylinder 20 rotates and causes the driving tooth 21 to push against the first gear 12 to rotate, the winding roller 10 rotates to retract the protective film 9 into the second outer cylinder 4, and the screen of the communication device 2 is exposed.

[0053] It should be noted that, when the protective film 9 is received in the second outer tube 4 , the protective film 9 pulls the rope 8 out of the first outer tube 3 , and at the same time, the inner tube 24 rotates to store force in the spiral spring 25 .

[0054] It is worth noting that during the rotation of the shaft 31, the fan blades 33 rotate, and the external air is drawn into the lower chamber 19 through the air inlet 34, and then the gas is successively input into the elastic bag 36 through the air outlet 35 and the air pipeline 37, and the elastic bag 36 expands; since the central angle of the sector gear 15 is 340 degrees, when the protective film 9 is completely retracted into the second outer tube 4, the sector gear 15 rotates until it no longer meshes with the second gear 13. At this time, the shaft 31 continues to rotate, but the winding roller 10 will no longer rotate.

[0055] As the rotating shaft 31 rotates continuously with the fan blades 33 , when the air pressure in the elastic bag 36 reaches a set value, the pressure relief valve 39 opens and sprays air toward the back of the communication device 2 , thereby improving the heat dissipation of the communication device 2 .

[0056] When the communication device 2 is finished using, the control unit 62 controls the motor 32 to drive the rotating shaft 31 to rotate in the opposite direction. Under the torsion force of the torsion spring 16, when the second gear 13 reverses, the second gear 13 will mesh with the fan gear 15, so that the fan gear 15 drives the driving cylinder 20 to rotate in the opposite direction, and the first gear 12 drives the winding roller 10 to rotate in the opposite direction. The winding roller 10 no longer pulls the protective film 9, and the spiral spring 25 releases the force to make the inner cylinder 24 rotate in the opposite direction. The winding ring 26 rotates synchronously with the inner cylinder 24 and makes the rope 8 retract into the first outer cylinder 3. At the same time, the rope 8 pulls the protective film 9 to make the protective film 9 be pulled out of the second outer cylinder 4. The protective film 9 is unfolded to protect the screen of the communication device 2. The protective film 9 has the function of shading and dustproofing the screen of the communication device 2, and when a foreign object hits the device head-on, the protective film 9 can provide protection to prevent the screen of the communication device 2 from being subjected to a large impact force and causing the screen to break.

[0057] Second embodiment:

[0058] like Figure 1 , Figure 6 and Figure 7As shown, in this embodiment, the protective film 9 is an airtight plastic film; a connecting ring 63 is rotatably connected to the inner bottom wall of the driving cylinder 20, and an electric spring 22 is installed between the inner top wall of the middle chamber 18 and the connecting ring 63; a tilt detection mechanism 7 is provided on the protective shell 1, and the tilt detection mechanism 7 is electrically connected to the electric spring 22; a second edge strip 29 is provided on the end of the protective film 9 passing through the second outer cylinder 4, and the end of the first edge strip 27 passing through the second outer cylinder 4 is fixedly connected to the second edge strip 29, and a first outer cylinder 3 is provided There is a hook 30 matching the second edge strip 29, and a slope is set on the side of the hook 30 close to the second edge strip 29. When the rope 8 is received into the first outer tube 3, the protective film 9 and the first edge strip 27 are pulled out from the second outer tube 4, and at the same time, the second edge strip 29 moves toward the hook 30. Through the slope on the hook 30, the hook 30 will not block the movement of the second edge strip 29. After the second edge strip 29 moves to be engaged with the hook 30, the hook 30 can block the reverse movement of the second edge strip 29.

[0059] The single turns of the electric spring 22 are set to be non-contact or insulated. When the electric spring 22 is energized, it is equivalent to an energized solenoid. Each turn of the spring is equivalent to a circular current. The current direction in each turn of the spring is the same. According to the mutual attraction between currents in the same direction, each turn of the spring attracts the adjacent springs, so the electric spring 22 will shrink as a whole.

[0060] In the initial state, the electric spring 22 is in an energized state, that is, the electric spring 22 is in a contracted state, and at this time, the driving tooth 21 on the driving cylinder 20 is meshed and connected with the first gear 12 .

[0061] like Figure 1 , Figure 3 and Fig.11 As shown, the tilt detection mechanism 7 includes a mounting tube 40 fixed to the bottom of the protective shell 1, a center axis 41 is coaxially fixedly connected inside the mounting tube 40, a first electrode block 42 is arranged on the inner top wall of the mounting tube 40, the electric spring 22 is electrically connected to the first electrode block 42, the first electrode block 42 is arranged in a ring shape, a collar 43 is rotatably connected to the center axis 41, a guide rod 44 is fixedly connected to the collar 43, a counterweight block 45 is slidably fitted on the guide rod 44, a tension spring 46 is installed between the collar 43 and the counterweight block 45, a second electrode block 47 is arranged on the counterweight block 45, and the first electrode block 42 is electrically connected to the second electrode block 47.

[0062] In the initial state, the first electrode block 42 and the second electrode block 47 are in contact, that is, the electric spring 22 is energized at this time; affected by various factors, when the device is hit by an external object and the external bracket falls over, the protective shell 1 will first tilt, and under the action of the gravity of the counterweight block 45, the counterweight block 45 slides along the guide rod 44 in the direction away from the ring 43, and the second electrode block 47 moves with the counterweight block 45, and the second electrode block 47 is no longer in contact with the first electrode block 42, the electric spring 22 is de-energized to expand the electric spring 22, and the electric spring 22 pushes against the connecting ring 63 to make the drive cylinder 20 move along the rotating rod 14 in the direction close to the fan gear 15, and the drive tooth 21 is no longer engaged with the first gear 12.

[0063] It should be noted that since the ring 43 can rotate, when the protective shell 1 tilts to either side, the ring 43 will rotate accordingly due to the gravity of the counterweight 45, causing the counterweight 45 to rotate to the bottom, and the counterweight 45 slides along the guide rod 44 in the direction away from the ring 43, ensuring that the protective shell 1 tilts to either side, and the electric spring 22 can unfold to disengage the drive tooth 21 from the first gear 12.

[0064] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the protective shell 1 is provided with a vent 48, the elastic bag 36 is fluidly connected to the vent 48, the protective shell 1 is provided with a slide groove 49, and a closing plate 50 is slidably matched on the slide groove 49. The closing plate 50 is used to close the vent 48. A push plate 51 is provided on the closing plate 50, and an elastic pull rope 52 is arranged between the inner wall of the slide groove 49 and the closing plate 50.

[0065] In the initial state, the closing plate 50 closes the vent 48 . When the protective film 9 is fully unfolded, the second edge strip 29 pushes against the push plate 51 to move the closing plate 50 along the slide groove 49 , so that the vent 48 is opened.

[0066] Based on the communication device protective case with charging function provided by the first embodiment, when the device in this embodiment is in use, it is affected by various factors (for example, an external object accidentally hits the external bracket). When the external bracket tilts to either side, the device first tilts, and under the gravity of the counterweight block 45, the counterweight block 45 slides along the guide rod 44 in the direction away from the ring 43, and the second electrode block 47 moves with the counterweight block 45. The second electrode block 47 is no longer in contact with the first electrode block 42, and the electric spring 22 is de-energized to expand the electric spring 22, which presses against the connecting ring 63 to drive The cylinder 20 moves along the rotating rod 14 toward the direction approaching the fan-shaped gear 15, and the driving tooth 21 is no longer engaged with the first gear 12, thereby releasing the limit on the winding roller 10, and the spiral spring 25 releases the force to make the inner cylinder 24 rotate in the opposite direction, and the winding ring 26 rotates synchronously with the inner cylinder 24 to make the rope 8 be received into the first outer cylinder 3. At the same time, the rope 8 pulls the protective film 9 to make the protective film 9 be pulled out from the second outer cylinder 4. The protective film 9 is fully unfolded to protect the screen of the communication device 2 to prevent the screen of the communication device 2 from being broken due to the front collision of the device with objects on the ground when the device is tilted.

[0067] It should be noted that, in the present embodiment, when the present device is used, the protective film 9 is retracted and extended as in the first embodiment, and the unfolding of the protective film 9 is controlled by the motor 32, but the motor 32 does not control the protective film 9 to be fully unfolded. The number of rotations of the motor 32 is controlled by the control unit 62, so that the unfolding amount of the protective film 9 is set to be able to cover the screen of the communication device 2. At this time, the second edge strip 29 will not resist the push plate 51; when the external bracket tilts, the spiral spring 25 releases the force to make the inner cylinder 24 rotate in the opposite direction. At this time, the protective film 9 is fully unfolded, and the second edge strip 29 moves to engage with the hook 30. The hook 30 can limit the position of the second edge strip 29 to prevent the protective film 9 from being subjected to a large impact force on the front side when the present device tilts, and the protective film 9 is retracted to the middle to a large extent, resulting in a large impact force on the screen of the communication device 2, and the screen of the communication device 2 is shattered.

[0068] It is worth mentioning that when the protective film 9 is fully unfolded, a cavity is formed between the screen of the communication device 2 and the protective film 9. At the moment when the protective film 9 is fully unfolded, the second edge strip 29 pushes against the push plate 51 to make the closing plate 50 move along the slide groove 49, and the vent 48 opens. The high-pressure gas in the elastic bag 36 is injected into the interior of the cavity through the vent 48. The air pressure in the cavity increases, and the protective film 9 expands slightly. When the device tilts and causes the protective film 9 to be impacted head-on, it can better cushion the impact, and the higher air pressure in the cavity can prevent the protective film 9 from being impacted and causing a large shrinkage, which causes the screen of the communication device 2 to be shattered.

[0071] The Bluetooth headset 61 is connected to the communication device 2 via Bluetooth. The Bluetooth headset 61 can reduce external interference during the user's communication. The control unit 62 can control the charging device 59 to charge the Bluetooth headset 61.
