The bottom cover 11, the rubber plate 2, the top cover 4 and the mounting ring 1 are designed to fit the contour of the circuit board 10, reducing the overall thickness and width. The mounting ring 1 is integrally formed, and the circuit board 10 cooperates with wireless charging and a touch-type internal switch, reducing the opening design of the mounting ring 1 and improving air tightness. Compared with the prior art, the ultra-thin design realized by the bottom cover 11, the rubber plate 2, the top cover 4 and the mounting ring 1 reduces the volume, making it more convenient to wear and use, and the reduced volume can also reduce the probability of collision.

[0041] The protective device 5 is also included for protecting the display 3; the protective device 5 includes four slide bars 51, and the four slide bars 51 are all installed on the top edge of the display 3. Two protective plates 52 are slidably installed on the four slide bars 51, and the two protective plates 52 are mirror-imaged. Two weights 53 are slidably installed on the top surface of the rubber plate 2 through a slide rail, and the two weights 53 are respectively located in front of and behind the display 3. When the mounting ring 1 and the rubber plate 2 swing violently, one of the weights 53 slides away from the display 3 due to inertia, and the end of the weight 53 away from the display 3 is connected The slide 54 is connected, and the weight 53 drives the slide 54 to move synchronously. The inner wall of the mounting ring 1 is connected to two pads 55. The bottom surfaces of the two pads 55 are connected to the top surface of the rubber plate 2. Reset springs are respectively arranged between the two pads 55 and the two slides 54. The top surface of the rubber plate 2 is rotatably mounted with four rotating rods 56 through the bracket. The four rotating rods 56 are divided into two groups. The two groups of rotating rods 56 are respectively located in front of and behind the display 3. The two ends of the slide 54 are respectively slidably hinged with one end of the two rotating rods 56 of one group. The two rotating rods 56 of the same group are away from the slide 54. One end is slidably hinged with the bottom surface of one of the protective plates 52. When the slide 54 moves, it drives the two rotating rods 56 of the same group to swing. The two rotating rods 56 use the principle of leverage to drive the protective plates 52 connected thereto to move in the direction close to the display 3. A gear 57 is rotatably installed on the right side of the display 3. The right side of the protective plate 52 located at the rear is connected to a first rack 58 through a bracket. The right side of the protective plate 52 located at the left is connected to a second rack 59 through a bracket. The first rack 58 and the second rack 59 are centrally symmetrically arranged with the gear 57 as the center. The first rack 58 and the second rack 59 are centrally symmetrically arranged with the gear 57 as the center. The first rack 58 and the second rack 59 are meshed with the gear 57. The first rack 58 and the second rack 59 can move synchronously in the opposite direction by virtue of the meshing relationship, so that when one of the protective plates 52 moves, it can drive the other protective plate 52 to move synchronously in the opposite direction, thereby achieving the effect that the two protective plates 52 can move in the direction close to each other. When the two protective plates 52 are closed, they cover the top of the display 3 to protect the display 3. When the inertia disappears, the two slides 54 are reset by the reset springs on the two pads 55, and the two weights 53 and the two protective plates 52 are reset accordingly.The protective device 5 also includes a shock-absorbing part 6, which includes four sliding arms 62. The four sliding arms 62 are all slidably mounted on the inner wall of the mounting ring 1. The four rotating rods 56 are respectively hinged with bent rods 61, and the ends of the four bent rods 61 away from the rotating rods 56 are respectively hinged with the four sliding arms 62. Four No. 1 rings 63 are installed through the inner wall of the mounting ring 1. When the rotating rod 56 swings, the sliding arms 62 are driven by the bent rods 61 to slide in the direction close to the No. 1 ring 63. The inner walls of the four No. 1 rings 63 are respectively slidably connected with shock-absorbing columns 64. Four reset springs 65 are installed on the inner wall of the mounting ring 1. The four reset springs 65 are respectively connected to the four shock-absorbing columns 64. An inclined surface end is provided on the sliding arm 62, and an inclined surface is provided on the shock-absorbing column 64. The inclined surfaces of the four sliding arms 62 are respectively in contact with the inclined surfaces of the four shock-absorbing columns 64 during movement. During the sliding process, the inclined surface end above the sliding arm 62 is in contact with the inclined surface of the shock-absorbing column 64, so that The shock-absorbing column 64 is subjected to the reverse thrust of the sliding arm 62 and slides in the direction away from the display 3, so that the shock-absorbing column 64 can protrude from the outer wall of the mounting ring 1. The shock-absorbing column 64 is made of elastic material. After protruding, the four shock-absorbing columns 64 can play a certain protective role on the outer wall of the mounting ring 1; through the setting of the protective device 5, when the user's hand shakes significantly, the two protective plates 52 can automatically close to protect the display 3, so as to prevent the display 3 from colliding and being damaged in the process of following the hand movement. When the user's hand stops shaking, the two protective plates 52 automatically open without affecting the observation time; through the setting of the shock-absorbing part 6, when the two protective plates 52 are closed, the four shock-absorbing columns 64 automatically protrude from the outside of the mounting ring 1. When the outer wall of the mounting ring 1 is hit, the impacting object first contacts one of the shock-absorbing columns 64, so that the shock-absorbing column 64 absorbs part of the potential energy and reduces the impact force on the mounting ring 1. ;

[0042] For further information, see Figure 8 - Fig. 9, the switching device 7 is used to actively switch the protection mode. The switching device 7 includes a second ring 71, which is installed on the inner wall of the mounting ring 1 through the second ring 71. The second ring 71 is located on the right side of the gear 57. The inner wall of the second ring 71 is slidably and rotatably connected with a rotating shaft 72. The right end of the rotating shaft 72 is connected with a hand wheel 73. The outer wall of the mounting ring 1 is connected with a limited groove cover 75. The outer wall of the rotating shaft 72 is connected with two limiting rods 74. The left end of the rotating shaft 72 and the gear member 57 are respectively connected with docking blocks 77. The inner wall of the mounting ring 1 is connected with a spring. The inner wall of the reset ring 76 is rotatably connected to the outer wall of the rotating shaft 72. The limiting groove cover 75 is provided with two limiting grooves. The two limiting rods 74 pass through the two limiting grooves of the limiting groove cover 75 when moving. When the rotating shaft 72 starts to move to the left, the two limiting rods 74 pass through the two limiting grooves on the limiting groove cover 75, so that the two limiting rods 74 move to the inside of the limiting groove cover 75. When the rotating shaft 72 rotates, the two limiting rods 74 rotate synchronously. When the two protective plates 52 are closed, the two limiting rods 74 are misaligned with the two limiting grooves, so that The inner wall of the limiting groove cover 75 abuts against the two limiting rods 74, achieving the effect of horizontally limiting the rotating shaft 72. The docking block 77 on the rotating shaft 72 contacts the docking block 77 on the gear 57 during movement, and the two docking blocks 77 can be snapped together. When the docking block 77 on the rotating shaft 72 rotates clockwise, it can drive the docking block 77 on the gear 57 to rotate clockwise, and the gear 57 rotates clockwise accordingly. The clockwise rotation of the gear 57 can drive the two protective plates 52 to close through the No. 1 rack 58 and the No. 2 rack 59, achieving The two protective plates 52 remain in a closed state, and the four shock-absorbing columns 64 also automatically protrude and remain in a protruding state, providing continuous protection; through the setting of the switching device 7, the user can press and turn the hand wheel 73 to enable the two protective plates 52 and the four shock-absorbing columns 64 to continue to maintain a protective state, which is convenient for use when continuous protection is required. The user can also turn the hand wheel 73 to turn off the continuous protection state, so that the two protective plates 52 and the four shock-absorbing columns 64 are restored to a state where they can automatically trigger protection.

[0043] Further, see Fig.10 - Fig.14The dustproof device 8 is used to prevent dust from entering the top cover 4. The dustproof device 8 includes a dustproof frame 81. The bottom surface of the top cover 4 is provided with a mounting groove. The dustproof frame 81 is installed in the mounting groove on the bottom surface of the top cover 4 through multiple springs. The bottom surface of the dustproof frame 81 abuts against the two protective plates 52. The dustproof frame 81 continuously applies pressure to the top surfaces of the two protective plates 52 and the two sliding rods 51 through elastic force to improve the air tightness of the protection frame. The left and right sides of the dustproof frame 81 are respectively connected to two inclined panels 82, and the left and right sides of the protective plate 52 are respectively connected to protrusions 83. The top surface of the protrusion 83 is connected to an inclined block 84. The top surfaces of the four inclined blocks 84 are respectively in sliding contact with the bottom surfaces of the four inclined panels 82. When the two protective plates 52 are close to each other, the four The inclined plane block 84 first pushes the dustproof frame 81 upward through the four inclined panels 82, so that the dustproof frame 81 is out of contact with the top surfaces of the two protective plates 52 to reduce the friction force on the protective plates 52 when they move. When the two protective plates 52 are about to close, the dustproof frame 81 is reset downward. After the two protective plates 52 are closed, the dustproof frame 81 squeezes the top surfaces of the two protective plates 52 again to achieve the dustproof effect. The dustproof device 8 also includes a supporting part 9, and the supporting part 9 includes two supporting frames 91. The two supporting frames 91 are both installed on the top surface of the rubber plate 2. The two supporting frames 91 are respectively located on the left and right sides of the display 3. A supporting block 92 is installed on the top of the supporting frame 91. The inner wall of the supporting block 92 is slidably connected with a resistance block 94. The bottom of the resistance block 94 is provided with The return spring and the inner wall of the support frame 91 are rotatably installed with two support rods 93, and the two support rods 93 are mirror-imaged. The two protrusions 83 on the same side of the support frame 91 are in contact with the resistance block 94 during the movement. The resistance block 94 contacts the two support rods 93 when it moves. When the two protrusions 83 are close to each other and are about to contact, the two protrusions 83 press the resistance block 94 downward. When the resistance block 94 moves downward, it drives the two support rods 93 to swing, so that the two support rods 93 contact the bottom surface of the protrusion 83. At this time, the top of the support frame 91, the resistance block 94, the two support rods 93 and the support block 92 form a plane, and the two support frames 91, the four support rods 93 and the two support blocks 92 cooperate with the four protrusions 83 to support the two protective plates 52. The dustproof frame 81 can play a certain dustproof role by providing the dustproof device 8, so as to prevent dust from entering the mounting ring 1 through the gap between the top cover 4 and the protective plate 52. When the two protective plates 52 begin to close, the dustproof frame 81 can automatically rise to reduce the friction force on the two protective plates 52 during movement, so as to keep the two protective plates 52 running smoothly. When the two protective plates 52 are closed, the dustproof frame 81 is lowered and reset again to prevent dust. The support part 9 is provided so that when the two protective plates 52 are closed, the two support frames 91, the four support rods 93 and the two support blocks 92 can support the two protective plates 52 by cooperating with the four protrusions 83, so as to enhance the stability of the protective plates 52.

[0044] With the above structure, the working principle of this case is that the bottom surface of the bottom cover 11 and the outer wall of the mounting ring 1 are plated with a metal coating to increase the heat dissipation area and heat dissipation capacity of the bottom cover 11 and the mounting ring 1. The circuit board 10 is ultra-thin in design, which can reduce the main body thickness of the mounting ring 1 to achieve an ultra-thin design. The bottom cover 11, the rubber plate 2, the top cover 4 and the mounting ring 1 fit the contour design of the circuit board 10 to reduce the overall thickness and width; the mounting ring 1 is integrally formed, and the circuit board 10 cooperates with wireless charging and a touch-type internal switch to reduce the opening design of the mounting ring 1 and improve air tightness. Compared with the prior art, the ultra-thin design achieved by the bottom cover 11, the rubber plate 2, the top cover 4 and the mounting ring 1 reduces the volume and is more convenient to wear and use. The reduced volume can also reduce the probability of collision.

[0045] When the mounting ring 1 and the rubber plate 2 swing violently, one of the weights 53 slides in a direction away from the display 3 by inertia, and the weight 53 drives the slide 54 to move synchronously. When the slide 54 moves, it drives two rotating rods 56 in the same group to swing. The two rotating rods 56 use the lever principle to drive the protective plate 52 connected thereto to move in a direction close to the display 3. When the first rack 58 moves, it can drive the second rack 59 to move in the opposite direction through the gear 57. Conversely, when the second rack 59 moves, it can also drive the first rack 58 to move in the opposite direction through the gear 57, so that the first rack 58 and the second rack 59 can move in the opposite direction synchronously, so that one of the protective plates 52 moves. When the rotating rod 56 moves, it can drive the other protective plate 52 to move synchronously in the opposite direction, so that the two protective plates 52 can move in the direction close to each other. When the two protective plates 52 are closed, they cover the top of the display 3 to protect the display 3. When the inertia disappears, the two slides 54 are reset by the reset springs on the two pads 55, and the two weights 53 and the two protective plates 52 are reset accordingly; when the rotating rod 56 swings, it drives the sliding arm 62 to slide in the direction close to the No. 1 ring 63 through the curved rod 61. During the sliding process, the upper inclined surface end of the sliding arm 62 contacts the inclined surface of the shock-absorbing column 64, so that the shock-absorbing column 64 is subjected to the reverse thrust of the sliding arm 62 and moves away from the display 3. The four shock-absorbing columns 64 are made of elastic material. After protruding, they can play a certain protective role on the outer wall of the mounting ring 1. When the outer wall of the mounting ring 1 is hit, the impactor first contacts one of the shock-absorbing columns 64, so that the shock-absorbing column 64 can absorb part of the potential energy, thereby reducing the impact force on the mounting ring 1. When the rotating rod 56 is reset, the sliding arm 62 is driven to reset by the curved rod 61. When the sliding arm 62 is not in contact with the shock-absorbing column 64, the shock-absorbing column 64 is reset by the elastic force of the reset spring sheet 65. After reset, the four shock-absorbing columns 64 are retracted into the four No. 1 rings 63, so that the appearance of the mounting ring 1 is relatively flat and beautiful. Prevent protrusions from affecting use; through the setting of the protective device 5, when the user's hand shakes significantly, the two protective plates 52 can automatically close to protect the display 3, and prevent the display 3 from colliding and being damaged in the process of following the hand movement. When the user's hand stops shaking, the two protective plates 52 automatically open without affecting the observation time; through the setting of the shock-absorbing part 6, when the two protective plates 52 are closed, the four shock-absorbing columns 64 automatically protrude from the outside of the mounting ring 1. When the outer wall of the mounting ring 1 is impacted, the impactor first contacts one of the shock-absorbing columns 64, so that the shock-absorbing column 64 absorbs part of the potential energy and reduces the impact force on the mounting ring 1.

[0046] When the user needs to maintain the protection state for a long time, the user presses the hand wheel 73 to the left, and the hand wheel 73 drives the rotating shaft 72 to slide to the left on the second ring 71. The docking block 77 on the rotating shaft 72 abuts against the docking block 77 on the gear 57 during movement, and the two docking blocks 77 can be snapped together. When the docking block 77 on the rotating shaft 72 rotates clockwise, it can drive the docking block 77 on the gear 57 to rotate clockwise, and the gear 57 rotates clockwise accordingly. When the two docking blocks 77 abut, the user rotates the hand wheel 73 clockwise, and the hand wheel 73 drives the two docking blocks 77 to rotate clockwise through the rotating shaft 72, and the gear 57 rotates clockwise accordingly. The clockwise rotation can drive the two guard plates 52 to close through the No. 1 rack 58 and the No. 2 rack 59. When the two guard plates 52 are closed, the user stops rotating the hand wheel 73. When the shaft 72 starts to move to the left, the two limit rods 74 pass through the two limit grooves on the limit groove cover 75, so that the two limit rods 74 move to the inside of the limit groove cover 75. When the shaft 72 rotates, the two limit rods 74 rotate synchronously. When the two guard plates 52 are closed, the two limit rods 74 are misaligned with the two limit grooves, so that the inner wall of the limit groove cover 75 presses against the two limit rods 74, achieving the effect of horizontally limiting the shaft 72. At the same time, the reset ring The spring 76 uses the elastic force of the spring to apply a rightward pulling force to the shaft 72. When the user releases the hand wheel 73, the shaft 72 generates a rightward force, so that the two limit rods 74 press against the inner wall of the limit slot cover 75 to the right, thereby generating a certain friction force, so that the shaft 72 cannot rotate temporarily. The shaft 72 limits the gear 57 through the two docking blocks 77, so that the two protective plates 52 cannot be reset temporarily, so that the two protective plates 52 remain in the closed state. The four shock absorbing columns 64 also automatically protrude and remain in the protruding state to provide continuous protection. When the user needs to cancel the active protection mode, the user slowly turns the hand wheel 73. When the two limit rods 74 are pressed against the inner wall of the limit slot cover 75 to the right, a certain friction force is generated, so that the shaft 72 cannot rotate temporarily. When 74 coincides with the two limit grooves, the rotating shaft 72 resets to the right, the two docking blocks 77 are disconnected, the gear 57 and the two protective plates 52 are reset accordingly, and the four-box shock-absorbing columns 64 are also reset accordingly, and then they return to the state where they can automatically trigger the protection. Through the setting of the switching device 7, the user can press and turn the hand wheel 73 to enable the two protective plates 52 and the four shock-absorbing columns 64 to maintain the protection state continuously, which is convenient for use when continuous protection is required. The user can also turn the hand wheel 73 to turn off the continuous protection state, so that the two protective plates 52 and the four shock-absorbing columns 64 are restored to the state where they can automatically trigger the protection.

[0047] Under normal conditions, the edges of the two protective plates 52 and the two slide bars 51 surround the periphery of the image display position of the display 3 to form a protective frame to protect the display 3. The dustproof frame 81 in the mounting groove at the bottom of the top cover 4 continuously applies pressure to the top surfaces of the two protective plates 52 and the two slide bars 51 through elastic force, thereby improving the air tightness of the protective frame and preventing dust from entering the interior of the mounting ring 1 through the gap between the protective plates 52 and the top cover 4. When the two protective plates 52 begin to close, the protective plates 52 drive the protrusions 83 on both sides thereof to move synchronously. When the protrusions 83 move, they drive the inclined plane blocks 84 to move synchronously. Two inclined planes are arranged on the inclined plane plate 82. When the inclined plane block 84 does not move, the inclined plane block 84 fits with the inclined plane on the outer side of the inclined plane plate 82. After the block 84 moves, the inclined block 84 pushes up the inclined panel 82 along the inclined surface. When the inclined block 84 is about to move into place, the inclined surface inside the inclined panel 82 contacts and gradually fits with the inclined block 84. During this process, the inclined panel 82 resets downward, so that when the two protective plates 52 approach each other, the four inclined blocks 84 first push the dustproof frame 81 upward through the four inclined panels 82, so that the dustproof frame 81 is out of contact with the top surfaces of the two protective plates 52 to reduce the friction force on the protective plates 52 when they move. When the two protective plates 52 are about to close, the dustproof frame 81 resets downward. After the two protective plates 52 are closed, the dustproof frame 81 squeezes the top surfaces of the two protective plates 52 again to achieve a dustproof effect. The bottom surface of the dustproof frame 81 is set to an elastic material to provide The dustproof frame 81 can automatically rise when the two protective plates 52 move to eliminate the friction between the two protective plates 52 and avoid affecting the movement of the protective plates 52. When the two protective plates 52 are about to close, taking one of the support frames 91 as an example, when the two protrusions 83 are close to each other and are about to contact, the two protrusions 83 press the abutment block 94 downward, and when the abutment block 94 moves downward, it drives the two support rods 93 to swing, so that the ends of the two support rods 93 away from each other move upward, and the two support rods 93 swing upward and contact the bottom surface of the protrusion 83. At this time, the top of the support frame 91, the abutment block 94, the two support rods 93 and the support block 92 form a plane. When the two protrusions 83 contact, the two The two protective plates 52 are closed, and the two support rods 93 and the support block 92 play a certain supporting role on the two protrusions 83. Since the protrusions 83 are connected to the protective plates 52, the two support frames 91, the four support rods 93 and the two support blocks 92 cooperate with the four protrusions 83 to support the two protective plates 52, thereby enhancing the stability of the protective plates 52. The two support rods 93 do not contact the two protrusions 83 before the two protrusions 83 contact each other, thereby reducing the friction force on the two protrusions 83 during movement. After the two protrusions 83 contact each other, the two support rods 93 rise, thereby expanding the supporting area and optimizing the supporting effect. After the two protrusions 83 are separated and reset, the resistance block 94 is reset by the elastic force of the reset spring, and the two support rods 93 are reset by gravity.Through the setting of the dustproof device 8, the dustproof frame 81 can play a certain dustproof role, preventing dust from entering the mounting ring 1 through the gap between the top cover 4 and the protective plate 52. When the two protective plates 52 begin to close, the dustproof frame 81 can automatically rise to reduce the friction force of the two protective plates 52 during movement, and keep the two protective plates 52 running smoothly. When the two protective plates 52 are closed, the dustproof frame 81 is lowered and reset again to prevent dust. Through the setting of the supporting part 9, when the two protective plates 52 are closed, the two supporting frames 91, the four support rods 93 and the two support blocks 92 cooperate with the four protrusions 83 to support the two protective plates 52, thereby enhancing the stability of the protective plates 52. ;
