[0046] The inner diameter of one side of the through slot 414 matches the outer diameter of the shaft 4101, and the outer wall of the shaft 4101 is fixedly connected with a telescopic support plate 417, and both ends of the telescopic support plate 417 are fixedly connected with the shaft 4101, and the telescopic support plate 417 is set as a damping rod structure. Since the straight hinge rod 45 and the shaft 4101 are restricted, the entire device is temporarily restricted and is in an expanded state. The staff can pull out the protective box 3 on the other side and press the mounting seat 1 to one side of the movable plate 411. Since the movable plate 411 and the bottom plate 412 are set with a telescopic structure, the installation The seat 1 is tilted, the movable plate 411 and the bottom plate 412 are contracted, and the sliding seat 46 on the bottom plate 412 will gradually slide toward the inner side of the support seat 47. When the angle adjustment is completed, the withdrawn protective box 3 can be rotated downward by ninety degrees, and the side walls of the protective box 3 are in contact with the movable plate 411 and the bottom plate 412. Due to the magnetic attraction, the protective box 3 will push the locking plate 415 of the convex structure forward, and the two groups of notches 416 on the locking plate 415 are respectively plugged into the convex points 413 on the movable plate 411 and the bottom plate 412 to lock the telescopic state of the movable plate 411 and the bottom plate 412.

[0047] In this embodiment, Figure 7 As shown, the straight hinge rod 45 , the movable plate 411 and the bottom plate 412 are all metal plates, and the straight hinge rod 45 , the movable plate 411 and the bottom plate 412 are all arranged horizontally with the protection box 3 , so as to facilitate locking the support structure through the two protection boxes 3 .

[0048] In this embodiment, Figure 2 , Figure 4 Figure 5 and Figure 6 As shown, the protective box 3 includes an inner cavity 31, which is opened in the inner wall of the protective box 3, and a plurality of springs are fixedly connected to the inner wall of the inner cavity 31, and a cleaning plate 32 is fixedly connected to the bottom end of the spring, and a plurality of cleaning brushes are fixedly connected to the bottom end of the cleaning plate 32. Through the setting of the cleaning plate 32, the surface of the communication device body 2 can be cleaned when the protective box 3 is opened and closed to avoid affecting signal reception.

[0049] In this embodiment, Figure 2 , Figure 4 Figure 5 and Figure 6As shown, the protection box 3 also includes a limiting cavity 33, the limiting cavity 33 is opened in the protection box 3, and a limiting plate 34 is slidably connected to the inner wall of the limiting cavity 33, and the limiting plate 34 is a convex structure, the front end of the limiting plate 34 is fixedly connected to a spring telescopic rod 35, and the other end of the spring telescopic rod 35 is fixedly connected to the inner wall of the limiting cavity 33, the front end of the limiting plate 34 is plugged with a vertical plate 36, and a deep groove is opened on the outer wall of the vertical plate 36, and the inner diameter of the deep groove is the same as that of the limiting plate 3 4 matches the outer diameter, the bottom end of the vertical plate 36 is fixedly connected to the bottom end of the support seat 47, and the limit plates 34 on the protection boxes 3 on both sides are manually pulled. The limit plates 34 squeeze the spring telescopic rods 35, and the limit plates 34 are separated from the vertical plates 36. At this time, the mounting seat 1 is manually lifted upward. Since the vertical plates 36 are separated from the limit plates 34, the connection between the support seat 47 and the protection box 3 is released, so that the protection box 3 and the mounting seat 1 rise, and the support seat 47 moves downward due to gravity, which is convenient for the deployment of the equipment.

[0050] In this embodiment, Fig.14 , Fig.15 and Fig.16 As shown, the unfolding mechanism 4 also includes a storage chamber 418, a limiting box 419 is fixedly connected to the inner wall of the storage chamber 418, a transmission screw 420 is rotatably connected to the inner wall of the limiting box 419, and a gear plate 421 is threadedly connected to the outer wall of the transmission screw 420, and the front end of the gear plate 421 is meshedly connected to a toggle gear 422, a push plate 423 is horizontally arranged at the front end of the gear plate 421, the push plate 423 is threadedly connected to the transmission screw 420, and a contact block 424 is slidably connected to the top of the push plate 423, the contact block 424 is a spring rod structure, a V-shaped recessed groove 425 is opened at the front end of the contact block 424, and a round block 426 is horizontally arranged at the front end of the recessed groove 425, and the bottom end of the round block 426 is fixedly connected to the top of the limiting box 419;

[0051] The bottom end of the shifting gear 422 is rotatably connected to a first hinge plate 427, and the front end of the first hinge plate 427 is hinged to a second hinge plate 428, and the front end of the second hinge plate 428 is hinged to a sealing door 429, and the width of the sealing door 429 matches the width of the storage cavity 418;

[0052] The contact block 424 is a wedge-shaped block structure. The front end of the sliding seat 46 will fit with the contact block 424 on the pushing plate 423, pushing the pushing plate 423 to move forward together. The forward movement of the pushing plate 423 can drive the transmission screw 420 to rotate, and the transmission screw 420 drives the gear plate 421 at the rear end to move forward slowly. The gear plate 421 is meshed with the toggle gear 422, and by pushing the toggle gear 422 to rotate, the toggle gear 422 drives the first hinge plate 427 to rotate. When the first hinge plate 427 rotates, it can push the second hinge plate 428 forward, and the second hinge plate 428 pushes the sealing door 429 to open. When the sliding seat 46 continues to move forward, it pushes the contact block 424 and the round block 426 to release. Due to the setting of the V-shaped sunken groove 425, the round block 426 is squeezed by the groove wall of the sunken groove 425, pushing the contact block 424 to slide backward until the contact block 424 is separated from the sliding seat 46.

[0053] In this embodiment, Fig.15 and Fig.16 As shown, a recoil spring is fixedly connected to the inner wall of the limiting box 419, and the front end of the recoil spring is fitted and connected to the front end of the push plate 423, so that when the push plate 423 moves to the maximum distance, the contact block 424 on the push plate 423 is separated from the sliding seat 46, and the push plate 423 is reset by the recoil spring, so that the contact block 424 is separated from the round block 426. At this time, the contact block 424 is reset again, so that when the sliding seat 46 returns to its original position, the contact block 424 can be squeezed to shrink until the maximum distance is reached. Due to the wedge block structure of the contact block 424, the contact block 424 can be squeezed to shrink. At this time, the sliding seat 46 continues to move and reset, and the sealing door 429 will also rotate in the opposite direction to reset.

[0054] The use method and advantages of the present invention: The multifunctional protective shell of the mobile communication device has the following working process:

[0055] like Figures 1 to 16 As shown, the staff can manually pull the limit plates 34 on the protection boxes 3 on both sides, and the limit plates 34 squeeze the spring telescopic rods 35, so that the limit plates 34 are separated from the vertical plates 36. At this time, the mounting seat 1 is manually lifted upward. Since the vertical plates 36 are separated from the limit plates 34, the support seat 47 is disconnected from the protection box 3, so that the protection box 3 and the mounting seat 1 rise, and the support seat 47 moves downward due to gravity.

[0056] As the support base 47 moves downward, the straight hinge rod 45 in the support base 47 rotates with the bottom end of the mounting base 1. At the same time, the sliding seat 46 at the bottom end of the straight hinge rod 45 slides in the sliding slot, and the movable plate 411 and the bottom plate 412 perform the same movement. Then, when the two sliding seats 46 slide, the front end of the sliding seat 46 will fit with the contact block 424 on the push plate 423, pushing the push plate 423 to move forward together. The forward movement of the push plate 423 can drive the transmission lead screw 420 to rotate. The transmission lead screw 420 drives the gear plate 421 at the rear end to move forward slowly. The gear plate 421 meshes with the拨动 gear 422. By pushing the拨动 gear 422 to rotate, the拨动 gear 422 drives the first hinge plate 427 to rotate. When the first hinge plate 427 rotates, it can push the second hinge plate 428 to move forward, and the second hinge plate 428 pushes the sealing door 429 to open. When the sliding seat 46 continues to move forward, the push contact block 424 is disengaged from the round block 426. Due to the setting of the V-shaped recessed groove 425, the round block 426 is pushed by the extrusion of the groove wall of the recessed groove 425 to push the contact block 424 to slide backward until the contact block 424 is separated from the sliding seat 46. At this time, the sliding seat 46 continues to move forward until the movable plate 411 and the bottom plate 412 are fully unfolded;

[0057] Following that, the staff first completely withdraws the protective box 3 on one side of the straight hinge rod 45. The protective box 3 drives the rotating block 43 to slide in the movable groove 42 through the sliding plate 44. At this time, the protective box 3 is separated from the mounting base 1, but the inside of the protective box 3 is connected to the mounting base 1 through the sliding plate 44 and the rotating block 43. Then, when the protective box 3 is rotated, the protective box 3 rotates 90 degrees on the mounting base 1 through the rotating block 43. At this time, the side wall of the protective box 3 fits with the side wall of the straight hinge rod 45, magnetically adheres. At the same time, the fitting of the protective box 3 and the straight hinge rod 45 will squeeze the push plate 49 to move forward. The two ends of the U-shaped structure at the upper end of the push plate 49 are respectively in contact with and squeezed against the shaft end of the straight hinge rod 45 and the movable column 4104. Since the bottom end of the push plate 49 has a gear surface formed by machining, and the gear surface is meshed with the shaft end at the bottom end of the straight hinge rod 45, the shaft end at the bottom end of the straight hinge rod 45 is restricted. At the same time, as the movable column 4104 moves forward, the movable column 4104 moves forward to squeeze the spring, and the hinge block 4103 hinged on the outer wall of the movable column 4104 is pushed forward. The hinge block 4103 rotates counterclockwise, pushing the upper arc-shaped plate 4102 to rise. The arc-shaped plate 4102 unfolds on the outer wall of the shaft rod 4101 and fits with the inner wall of the straight hinge rod 45 to lock the shaft rod 4101, making the shaft rod 4101 unable to rotate and slide;

[0058] As the straight hinge rod 45 and the shaft rod 4101 are restricted, the entire device is temporarily restricted and in an unfolded state. The staff can pull out the protection box 3 on the other side and press the mounting seat 1 to one side of the movable plate 411. Since the movable plate 411 and the bottom plate 412 are provided with a telescopic structure, the mounting seat 1 is tilted, the movable plate 411 and the bottom plate 412 are contracted, and the sliding seat 46 on the bottom plate 412 gradually slides toward the inner side of the support seat 47. When the angle adjustment is completed, the pulled out protection box 3 can be rotated downward by ninety degrees. The side wall of the protective box 3 contacts the movable plate 411 and the bottom plate 412. Due to the magnetic attraction, the protective box 3 pushes the locking plate 415 of the convex structure forward. The two sets of notches 416 on the locking plate 415 are respectively plugged into the convex points 413 on the movable plate 411 and the bottom plate 412 to lock the telescopic state of the movable plate 411 and the bottom plate 412. At the same time, the movable rod at the other end of the telescopic support plate 417 is squeezed to lock the shaft rod 4101 at the other end of the telescopic support plate 417. At this time, the installation process is completed.

[0059] During the final disassembly, it is only necessary to reset the two protective boxes 3, and the push plate 49 and the locking plate 415 are pushed and reset by the reset of the movable column 4104, thereby releasing the restrictions on the straight hinge rod 45, the movable column 4104 and the bottom column. At this time, the mounting seat 1 is manually pulled upward to reset the movable plate 411 and the bottom plate 412, and the two sliding seats 46 are manually pushed inward again. At this time, the mounting seat 1 will automatically move downward due to the action of the gravity of the mounting seat 1, and the straight hinge rod 45 will rotate downward, and the movable plate 411 and the bottom plate 412 will shrink to the maximum value and perform the same movement until the straight hinge rod 45, the movable plate 411 and the bottom plate 412 are received in the support seat 47, completing the entire process.

[0060] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
