[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 6 shown, the present invention provides a magnetic attraction type extended screen connection structure, including a base 1, and further including:

[0034] A connection mechanism 4, the connection mechanism 4 is detachably installed outside the adjustment mechanism 3, and a magnetic attraction mobile phone case 5 and an extended screen main body 6 are arranged outside the connection mechanism 4;

[0035] A support mechanism 2, the support mechanism 2 is arranged in the inner wall of the base 1;

[0036] An adjustment mechanism 3, the adjustment mechanism 3 is arranged outside the support mechanism 2;

[0037] Wherein, the connection mechanism 4 includes a connecting plate 401, a secondary plate 402 is hinged to the outer wall of the connecting plate 401, and a clamping block 406 is slidably connected to the inner wall of the secondary plate 402;

[0038] The support mechanism 2 includes a bracket 201, and a support rod 202 is hinged to the inner wall of the bracket 201;

[0039] The adjustment mechanism 3 includes a moving block 301, a convex block 306 is slidably connected to the inner wall of the moving block 301, and a T-shaped block 302 is fixedly connected to the outer wall of the moving block 301.

[0040] Adopting the above scheme: The base 1 is used as a support component of the overall device and can be placed on the desktop for use; the magnetic attraction mobile phone case 5 can hold a mobile phone, fix the mobile phone through an internal magnet, and set up a second screen display on the mobile phone to be projected onto the extended screen main body 6, so as to see the required scene application pictures on the extended screen main body 6; through the connection mechanism 4, the magnetic attraction mobile phone case 5 and the extended screen main body 6 can be disassembled and installed conveniently and quickly to replace devices of different sizes according to needs; the support mechanism 2 can retract or expand the bracket 201, and can be retracted into the base 1 to save space when not in use; the adjustment mechanism 3 can adjust the height of the magnetic attraction mobile phone case 5 and the extended screen main body 6 and can be adjusted according to the user's comfort level.

[0041] As Figures 3 to 4As shown, the outer wall of the card block 406 is hinged with the moving rod 404 through the hinge rod 405, and the moving rod 404 is elastically connected to the inner wall of the sub-plate 402 through the connecting spring 403. The top outer wall of the moving rod 404 is fixedly connected with the shift block 407, and the outer walls of the magnetic mobile phone box 5 and the extended screen body 6 are fixedly connected with the mounting block 408. The inner wall of the mounting block 408 is provided with a card slot 409.

[0042] The above solution is adopted: two sets of sub-plates 402 are provided, which are respectively hinged on the outer walls of the two sides of the connecting plate 401, and the connection between the two is a friction hinge. When not in use, the two sets of sub-plates 402 can be flipped to the middle and maintained in this state under the friction force of the hinge, such as Figure 2 As shown, it can also be unfolded for use when in use. The friction type hinge is a prior art and will not be described in detail here. The mounting block 408 can be installed on the sub-board 402 to install the magnetic mobile phone box 5 and the extended screen body 6.

[0043] like Figures 3 to 4 As shown, the two ends of the hinged rod 405 are respectively hinged to the outer walls of the moving rod 404 and the clamping block 406, one end of the connecting spring 403 is fixedly connected to the inner wall of the sub-plate 402, and the other end of the connecting spring 403 is fixedly connected to the outer wall of the moving rod 404; the moving rod 404 is slidably connected to the inner wall of the sub-plate 402, the clamping block 406 is clamped in the slot 409, and the mounting block 408 is in contact with the outer wall of the sub-plate 402.

[0044] The above scheme is adopted: the shift block 407 passes through the top outer wall of the sub-plate 402. Under normal circumstances, the connecting spring 403 keeps the moving rod 404 at a certain position on the inner wall of the sub-plate 402 due to its own elastic force. At this time, the two groups of hinged rods 405 drive the card block 406 to remain in a pop-up state on both sides, and can be engaged with the card slot 409 in the mounting block 408 to fix the magnetic mobile phone box 5 and the extended screen main body 6; when the shift block 407 is shifted, the moving rod 404 will be driven to move synchronously, squeezing the connecting spring 403. When the moving rod 404 moves, it will drive the two groups of hinged rods 405 to flip toward the middle. Since the card block 406 is slidably connected to the inner wall of the sub-plate 402, the card block 406 can be driven by the hinged rod 405 to move into the inner wall of the sub-plate 402, and disengage from the card slot 409, thereby releasing the limit of the mounting block 408, and removing the magnetic mobile phone box 5 and the extended screen main body 6, which is more convenient to operate.

[0045] like Figure 4 As shown, the inner wall of the magnetic mobile phone box 5 is elastically connected to the limit block 8 through the return spring 7, one end of the return spring 7 is fixedly connected to the outer wall of the limit block 8, and the other end of the return spring 7 is fixedly connected to the inner wall of the magnetic mobile phone box 5, and the limit block 8 is slidably connected to the inner wall of the magnetic mobile phone box 5.

[0046] The above scheme is adopted: the user's mobile phone can be placed in the magnetic mobile phone box 5, and the mobile phone can be fixed by the magnetic suction force designed on its inner wall. The upper and lower inner walls of the magnetic mobile phone box 5 are provided with reset springs 7 and limit blocks 8. After the mobile phone is placed in the magnetic mobile phone box 5, the limit blocks 8 will pop out and squeeze the upper and lower ends of the mobile phone under the elastic force of the reset spring 7, so as to further fix the mobile phone, and the limit blocks 8 can move up and down in the inner wall of the magnetic mobile phone box 5, which can have a certain fixing effect on mobile phones of different sizes; the magnetic mobile phone box 5 and the extended screen body 6 can both rotate on the outer wall of the mounting block 408 to adjust different angles of the mobile phone or the extended screen body 6. This part is the existing technology.

[0047] like Figure 5 As shown, the outer wall of the support rod 202 is rotatably connected to the sliding rod 203, the outer wall of the sliding rod 203 is fixedly connected to the sliding block 204, the inner wall of the sliding block 204 is elastically connected to the plug block 206 through the telescopic spring 205, and the outer wall of the base 1 is provided with a slot 207; the two ends of the support rod 202 are respectively hinged to the inner wall of the bracket 201 and the base 1, the bracket 201 is hinged in the inner wall of the base 1, and the sliding rod 203 is slidably connected to the outer wall of the base 1; one end of the telescopic spring 205 is fixedly connected to the outer wall of the plug block 206, and the other end of the telescopic spring 205 is fixedly connected to the inner wall of the sliding block 204, the plug block 206 is slidably connected to the inner wall of the sliding block 204, and the plug block 206 is snap-fitted into the slot 207.

[0048] The above solution is adopted: the sliding rod 203 passes through the outer wall of one side of the base 1, and the slider 204 is slidably connected to the outer wall of the base 1; the bracket 201 can be turned along the connection point between it and the base 1, and one end of the support rod 202 can be turned in the inner wall of the bracket 201, and the other end can be driven to move by toggling the slider 204; Figure 2 As shown, there are two groups of slots 207 . When the support mechanism 2 is folded, the insert block 206 in the slide block 204 is engaged with the right group of slots 207 . When the support mechanism 2 is unfolded, the insert block 206 is engaged with the left group of slots 207 .

[0049] Due to its own elastic force, the telescopic spring 205 will always keep the plug block 206 engaged with the slot 207. When the plug block 206 is pulled, it can be disengaged from the slot 207, compressing the telescopic spring 205, thereby releasing the limit of the slider 204 and moving it laterally; when the slider 204 is moved laterally, the end of the support rod 202 provided with the slide rod 203 moves laterally, and the end hinged to the bracket 201 will flip over, and drive the bracket 201 to flip up and down, so that the support mechanism 2 can be unfolded or folded, and can be put into the base 1 when not in use, saving space and being easy to carry.

[0050] like Figure 6As shown, the inner wall of the moving block 301 is elastically connected to the trapezoidal block 304 through the compression spring 303, the outer wall of the protrusion 306 is fixedly connected to the short rod 305, and the outer wall of the bracket 201 is provided with a T-slot 307 and a groove 308.

[0051] The above scheme is adopted: under normal conditions, the compression spring 303 keeps the trapezoidal block 304 in a certain position under the action of its own elastic force. At this time, the short rod 305 contacts the inclined surface of the long side of the trapezoidal block 304, so that the protrusion 306 is always engaged with a group of grooves 308, fixing the position of the movable block 301, and fixing the magnetic mobile phone box 5 and the extended screen body 6 in a certain position; the top outer wall of the trapezoidal block 304 is provided with a pressing block, which passes through the outer wall of the movable block 301; the connecting plate 401 can be installed on the outer wall of the movable block 301, so as to support the magnetic mobile phone box 5 and the extended screen body 6, and the connecting plate 401 can be rotated after installation to adjust the angle between the magnetic mobile phone box 5 and the extended screen body 6 to meet the different viewing needs of users, and the structures installed on the rotation are all prior art.

[0052] like Figure 6 As shown, the moving block 301 is fixedly connected to the outer wall of the bracket 201, the connecting plate 401 is detachably installed on the outer wall of the moving block 301, one end of the compression spring 303 is fixedly connected to the outer wall of the trapezoidal block 304, the other end of the compression spring 303 is fixedly connected to the inner wall of the moving block 301, the trapezoidal block 304 is slidably connected to the inner wall of the moving block 301, the short rod 305 is slidably connected to the outer wall of the trapezoidal block 304, the T-block 302 is clamped with the T-slot 307, and the protrusion 306 is clamped with the groove 308.

[0053] The above scheme is adopted: when the pressing rod on the outer wall of the trapezoidal block 304 is pressed downward, the trapezoidal block 304 will be driven to move downward, and then the short rod 305 will slide along its inclined surface. Since the short rod 305 can only move horizontally, it can be moved to the short side inclined surface of the trapezoidal block 304, driving the protrusion 306 to move into the inner wall of the moving block 301 and disengage from the groove 308, so that the moving block 301 can be moved up and down to adjust the height; the T-block 302 and the T-slot 307 are always engaged, so that the moving block 301 will not be separated from the outer wall of the bracket 201; when the moving block 301 moves to the appropriate position, the compression spring 303 drives the trapezoidal block 304 to reset, and its inclined surface squeezes the short rod 305 and then drives the protrusion 306 to pop out and engage with a group of grooves 308, completing the height fixation of the magnetic mobile phone box 5 and the extended screen body 6.

[0054] The working principle and use process of the present invention:

[0055] Place the base 1 on a stable desktop, pull the insert block 206 on the slider 204 to disengage it from the right slot 207, move the slider 204 horizontally, and drive the bracket 201 to flip upward through the support rod 202 until the insert block 206 engages with the left slot 207 to complete the deployment of the support mechanism 2. At this time, the bracket 201 extends from the base 1 and is fixed.

[0056] Then the connecting plate 401 can be installed on the outer wall of the moving block 301 to ensure a firm connection. At this time, the connecting plate 401 can rotate around the connection point with the moving block 301 to facilitate subsequent angle adjustment; unfold the sub-plate 402 from both sides of the connecting plate 401. The connection between the sub-plate 402 and the connecting plate 401 is a friction hinge, which can maintain the unfolded state under the friction force of the hinge after unfolding; then move the dial block 407 to move the card block 406 to the inner wall of the sub-plate 402, and place the mounting block 408 of the magnetic mobile phone box 5 and the extended screen body 6 on the sub-plate 402. The card block 406 is engaged with the card slot 409 to complete the fixation of the magnetic mobile phone box 5 and the extended screen body 6.

[0057] Put the mobile phone into the magnetic mobile phone box 5, and use the magnetic suction force of the inner wall of the magnetic mobile phone box 5 to fix the mobile phone. At the same time, the return springs 7 on the upper and lower inner walls of the magnetic mobile phone box 5 will push the limit blocks 8 to pop out, squeezing the upper and lower ends of the mobile phone to further fix the mobile phone; set the second screen display function on the mobile phone, project the mobile phone screen onto the extended screen body 6, and the user can see the required scene application screen on the extended screen body 6.

[0058] The connecting plate 401 can rotate around the connection point with the moving block 301, so as to adjust the angle of the magnetic mobile phone box 5 and the extended screen body 6 to meet the different viewing needs of users; at the same time, the magnetic mobile phone box 5 and the extended screen body 6 can both rotate on the outer wall of the mounting block 408 to further adjust the angle of the mobile phone or the extended screen body 6.

[0059] When it is necessary to adjust the height of the magnetic mobile phone box 5 and the extended screen body 6, press the pressing block on the outer wall of the top end of the trapezoidal block 304 downward to drive the trapezoidal block 304 to move downward, and the short rod 305 drives the protrusion 306 to move out of contact with the groove 308. At this time, the moving block 301 can be moved up and down to adjust the height. After the moving block 301 moves to the appropriate position, release the pressing block, and the compression spring 303 drives the trapezoidal block 304 to reset, and drives the protrusion 306 to pop out and engage with a group of grooves 308 through the short rod 305 to complete the height fixation.

[0060] When the device needs to be disassembled and carried, the dial block 407 can be toggled, and the clamping block 406 is driven by the hinge rod 405 to disengage from the clamping groove 409, releasing the limit of the mounting block 408, and the magnetic mobile phone box 5 and the expansion screen main body 6 are removed from the secondary board 402; then the connecting plate 401 is disassembled from the outer wall of the moving block 301, the insertion block 206 is pulled and the sliding block 204 is moved horizontally, so that the bracket 201 is turned downward and retracted into the base 1, completing the retraction of the support mechanism 2. The split design can save occupied space, and the operations of assembly and separation are relatively convenient, facilitating carrying.
