DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention provides a wirelessly connected network computer, which solves the problem that the keyboard 22 of the notebook computer cannot be adjusted relative to the screen 1, causing the user to have an uncomfortable posture and thus burdening the user's neck, back and wrists.

[0038] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems, and the overall idea is as follows: by opening a keyboard groove 21 on the upper surface of the base 2, the keyboard 22 is fixed on the surface of the sliding device 4, and the sliding device 4 can slide in the keyboard groove 21 to change the distance relative to the screen 1, thereby adjusting the position of the keyboard 22 thereon, so that people can find a more comfortable distance for the keyboard 22 suitable for their own operation, thereby reducing the burden on the person's body during use.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The present invention provides a wireless connection type network computer, comprising: a screen 1 and a base 2, wherein the bottom edge of the screen 1 and the top edge of the base 2 are connected via a hinge 3, an interface 11 is provided on one side of the base 2, and further comprising:

[0041] Keyboard slot 21: The keyboard slot 21 is provided on the surface of the base 2 and has three side slot walls. The side away from the hinge 3 penetrates through the side of the base 2 and communicates with the outside.

[0042] Sliding device 4: the sliding device 4 is located inside the keyboard slot 21 and can slide relative to the keyboard slot 21;

[0043] Keyboard 22 : The keyboard 22 is fixed on the surface of the sliding device 4 .

[0044] The wireless connection type network computer of the present invention comprises a main body screen 1 and a base 2, which are connected by a hinge 3 and can rotate around each other through the hinge 3. A square keyboard slot 21 is provided on the upper surface of the base 2, and the side away from the hinge 3 penetrates the side of the base 2 and communicates with the outside, so that the sliding device 4 located inside it can slide out through the side to the outside, and the keyboard 22 is fixed on the surface of the sliding device 4. When the sliding device 4 slides to one side along the keyboard slot 21, the keyboard 22 on its surface will also move outward with it, so that its position relative to the screen 1 can be changed, thereby achieving the purpose of adjusting the position of the keyboard 22. According to the user's personal preference, the keyboard 22 can be placed in a relatively comfortable position when it is used, avoiding the keyboard 22 being too close to the screen 1, which is inconvenient to use and causes a burden on the user's neck, back and wrist.

[0045] As a specific embodiment of the present invention, the sliding device 4 includes:

[0046] Sliding plate 41: The sliding plate 41 is disposed in the keyboard slot 21, slidably connected to the keyboard slot 21, and has a size comparable to the keyboard slot 21, with its two sides and top being in contact with the side walls of the keyboard slot 21, the keyboard 22 being fixed on its upper surface, and the height of the upper surface of the keyboard 22 being slightly lower than the upper surface of the base 2;

[0047] Side sliding grooves 42: the side sliding grooves 42 are formed on the side walls of the keyboard slot 21 on both sides of the sliding plate 41;

[0048] Side sliding block 43 : the side sliding block 43 is located inside the side sliding groove 42 and can move along the side sliding groove 42 , and one end of the side sliding block 43 is fixedly connected to the side of the sliding plate 41 .

[0049] The sliding device 4 in the present invention is used to adjust the position of the keyboard 22 thereon, and it mainly includes a sliding plate 41, a side sliding groove 42 and a side sliding block 43. There are two side sliding grooves 42, which are in the same horizontal height and parallel to each other, and are opened on the side walls on both sides of the keyboard groove 21. They are used to limit the sliding of the sliding plate 41. The sliding plate 41 is the sliding body, which is located in the keyboard groove 21, and the keyboard 22 is arranged on it. In order to make its sliding direction always parallel to the side wall of the keyboard groove 21 when it slides relative to the keyboard groove 21, and does not separate from the keyboard groove 21, side sliding blocks 43 are fixed on both sides of its plate body, which are located in the side sliding grooves 42, and its thickness is slightly smaller than the thickness of the side sliding grooves 42, so that it can slide while ensuring that it does not separate from the side sliding grooves 42. When the side sliding block 43 is located at the top of the side sliding groove 42 close to the hinge 3 When the keyboard 22 is in the upper position, the sliding plate 41 is completely located in the keyboard groove 21, and the plate edge away from the hinge 3 is flush with the side edge of the base 2 at that position. When the side slider 43 is located at the top of the side slide groove 42 away from the hinge 3, this is the maximum sliding distance of the sliding plate 41 and also the maximum movement position of the keyboard 22. This can prevent the sliding plate 41 from sliding too far and causing it to fall off relative to the base 2, thereby causing damage to the keyboard 22. The device can realize the change of the position of the keyboard 22, thereby adapting to the different differences in the position requirements of different users for the keyboard 22 and improving the user experience. In the present invention, the keyboard 22 is fixed to the upper surface of the sliding plate 41, and the height of its upper surface is slightly lower than the upper surface of the base 2. This can prevent the keyboard 22 from colliding and scratching the screen 1 when the screen 1 and the base 2 are in contact when the body is closed.

[0050] As a specific embodiment of the present invention, the sliding plate 41 is fixedly connected to the plate body at one end near the hinge 3 with a long strip buckle 5, and a downward arc-shaped protrusion is provided at the bottom of the sliding plate 41. A slot 25 is opened inside the end of the base 2 near the hinge 3, and the side of the slot 25 is communicated with the keyboard slot 21. A long strip card seat 6 is provided in the slot 25, and an upper surface thereof is located on one side of the keyboard slot 21 and is provided with an upward arc-shaped protrusion, and the upward protrusion is at the same horizontal height as the downward protrusion of the long strip buckle 5. A spring 62 is fixed to the bottom of the long strip card seat 6, and the bottom end of the spring 62 is fixed to the inner wall of the base 2. A cylindrical button 61 is provided on the upper surface of the middle part of the long strip card seat 6, and the button 61 passes through the wall of the base 2 and is connected to the upper surface of the base 2, and its top is at the same horizontal height as the upper surface of the base 2.

[0051] In order to make the sliding plate 41 located inside the keyboard slot 21 and prevent the keyboard 22 from sliding out of the keyboard slot 21 when the body is moved when there is no need to change the position of the keyboard 22, the present invention provides a card slot 25 on the inner wall of the end of the base 2 near the hinge 3, and one side of the card slot 25 is connected to the keyboard slot 21, and a long card seat 6 is arranged inside it, the upper surface of which is located on one side of the sliding plate 41 and is provided with an upward arc-shaped protrusion, the bottom of which is provided with a spring 62 fixed to the inner wall of the base 2, and the top of the columnar button 61 is provided, which penetrates the wall of the base 2 and is connected to the upper surface of the base 2. Under normal conditions, the spring 62 gives the long card seat 6 an upward force. At this time, the arc-shaped protrusion is located above the bottom plane of the card slot 25, and the top of the button 61 is at the same height as the upper surface of the base 2. In this way, it can be avoided that the button 61 is accidentally touched by the hand, and it can also be prevented from hindering the process of the screen 1 and the base 2 fitting together and closing. At this time, if the sliding plate 41 does not slide relative to the keyboard slot 21 When the cam 25 is in the locked position, the upper and lower parts of the cam 25 are in the locked position, and the lower and upper parts of the cam 25 are in the locked position, so that the cam 25 can move in a certain direction and the upper and lower parts of the cam 25 are in a certain direction.

[0052] The purpose of setting the protrusions of the long card seat 6 and the long card buckle 5 in the present invention to be arc-shaped is to push the sliding plate 41 to slide into the keyboard slot 21, drive the long card seat 6 into the slot, and when the protrusion contacts the protrusion of the long card buckle 5, since they are each arc-shaped, the contact point is inclined along the tangent of the arc surface, which will generate a downward force, driving the long card seat 6 to overcome the elastic force of the bottom spring 62 and move downward, so that the arc-shaped protrusion of the long card buckle 5 can be moved to the inner side of the arc-shaped protrusion of the long card seat 6 relative to the slot. At this time, the contact point between the long card seat 6 and the long card buckle 5 disappears, and the long card seat 6 rebounds upward again under the force of the bottom spring 62 to complete the locking. There is no need to manually press the button 61 during the locking process to change the horizontal height of the long card seat 6, which simplifies the action of the locking process of the sliding plate 41;

[0053] The purpose of providing the long strip seat 6 and the long strip buckle 5 with a long strip shape in the present invention is to increase the contact area between each other, so that during the locking process or after locking, the driving and limiting forces are transmitted between each other more stably, avoiding excessive local force and thus causing damage to the whole.

[0054] As a specific implementation of the present invention, the long strip buckle 5 and the long strip holder 6 are both made of polypropylene material.

[0055] In the present invention, the long strip buckle 5 and the long strip holder 6 are both made of polypropylene material, which has good wear resistance and high-strength mechanical properties, as well as heat-resistant and insulating properties, and can meet the working requirements of the long strip buckle 5 and the long strip holder 6.

[0056] As a specific implementation of the present invention, the sliding plate 41 is made of polytetrafluoroethylene material.

[0057] The sliding plate 41 described in the present invention is made of polytetrafluoroethylene material, which has excellent chemical stability, corrosion resistance and sealing. It is highly lubricated and has good electrical insulation. It is also resistant to high temperature and oxidation, which fully meets the requirements that the sliding plate 41 carries the keyboard 22 and needs to slide in the keyboard slot 21.

[0058] As a specific embodiment of the present invention, the base 2 is provided with three slots 23 connected to the side and the bottom on the side away from the hinge 3, and a support foot 44 made of the same rubber material is provided therein, and the top of the support foot 44 is fixedly connected to the bottom of the sliding plate 41.

[0059] When the keyboard 22 on the surface of the sliding plate 41 is struck, the support leg 44 is in a position to move the keyboard 22 to the outside of the keyboard slot 21, and the support leg 44 is in a position to move the keyboard 22 to the inside of the keyboard slot 21, and ...

[0060] As a specific embodiment of the present invention, the keyboard slot 21 is located at the bottom of the slot at one end of the hinge 3, and a semi-arc long slot 7 is opened, one end of which penetrates through the side outer wall of the base 2 to communicate with the outside world. A long strip dust removal box 71 is provided in the long slot 7. The dust removal box 71 is located at one end of the long slot 7 penetrating the side outer wall of the base 2, and its end face is horizontally consistent with the side wall of the base 2, and the end face is rotatably connected to a pull ring 72.

[0061] In the present invention, after the keyboard 22 slides out of the keyboard slot 21 along with the sliding plate 41, part of the slot body of the keyboard slot 21 is exposed to the air, and dust will inevitably accumulate inside it after long-term use. Therefore, a semi-arc-shaped long slot 7 is opened at the bottom of the slot at one end of the hinge 3 of the keyboard slot 21, one end of which penetrates to the outer wall of the side of the base 2 and communicates with the outside world. A dust removal box 71 with a length equivalent to the long slot 7 and a pull ring 72 rotatably connected at one end is located inside the long slot 7, and the outer wall of the box body is also semi-arc-shaped and fits the inner wall of the long slot 7. One end of the pull ring 72 is located on the side of the side wall of the base 2 penetrated by the long slot 7. Since the bottom surface of the sliding plate 41 fits the bottom surface of the keyboard slot 21, when the sliding plate 41 slides inward, its end surface located inside the keyboard slot 21 will push the dust inside the keyboard slot 21 that has been scratched to move toward the dust removal box 71. When the dust is above the dust box 71, it will fall into the dust box 71 due to the action of gravity. The dust in the keyboard slot 21 can also be manually swept into the dust box 71 with a soft brush, which is convenient for cleaning the dust in the keyboard slot 21 and avoiding its accumulation and eventually hindering the movement of the sliding plate 41. The dust accumulated in the dust box 71 can be pulled out of the long slot 7 from the side of the base 2 by pulling the pull ring 72 at its end, and then the dust inside it can be dumped. After dumping, the port of the long slot 7 on the side of the base 2 can be inserted back; in the present invention, the pull ring 72 is rotatably connected to the end of the dust box 71, and under its own gravity, its end is vertically downward along the rotation point and parallel to the side wall of the base 2, so that the side wall of the base 2 will not be obviously protruding, maintaining its overall aesthetics.

[0062] As a specific embodiment of the present invention, the inner side of the end of the long groove 7 communicating with the outside is fixedly connected to a first magnetic strip 73, and the end of the dust removal box 71 is fixedly connected to the edge of one end with a pull ring 72 fixedly connected to a second magnetic strip 74.

[0063] In order to prevent the dust box 71 in the long groove 7 from sliding out to one side under the vibration generated when the body is moved, in the present invention, a No. 1 magnetic strip 73 is fixed to one end of the long groove 7 that passes through the side wall of the base 2, and a No. 2 magnetic strip 74 is fixed to the outer side of the end of the dust box 71. The No. 1 magnetic strip 73 and the No. 2 magnetic strip 74 attract each other. When the dust box 71 is located in the long groove 7, the No. 1 magnetic strip 73 and the No. 2 magnetic strip 74 contact and adsorb each other, so that the dust box 71 is not easy to fall out of the long groove 7 under slight external vibration.

[0064] As a specific embodiment of the present invention, the hinge 3 is keyway-shaped and is divided into two ends, wherein the upper end and the lower end are respectively rotatably connected to the screen 1 and the base 2, and the screen 1 and the base 2 can both rotate 360° around their rotatable connection.

[0065] The screen 1 of a conventional laptop computer has a limited rotation range relative to the base 2, so the base 2 must be located on the display side of the screen 1. When assembling an external keyboard, if the external keyboard is placed on the base 2, the keyboard 22 on the surface of the base 2 is easily damaged. If the external keyboard is placed on a desktop on the side of the base 2 away from the screen 1, it is far away from the screen 1, which causes discomfort to some people. The hinge 3 in the present invention is in the shape of a key slot, which is divided into two ends. The upper and lower ends are respectively rotatably connected to the screen 1 and one side of the base 2, and the screen 1 and the base 2 can both rotate 360° around their rotation connection, so that the base 2 can be attached to the display side of the screen 1 or to the back of the screen 1. When it is necessary to install an external keyboard, the connection line of the external keyboard can be connected to the interface 11 on the side of the base 2, and the base 2 is rotated to the back of the screen 1 to form a bracket, so that a larger space is available for placing the external keyboard when installing it, which is convenient for debugging the position of the screen 1.

[0066] As a specific implementation of the present invention, rubber strips 24 are fixedly connected to the upper surface edges of both sides of the base 2 .

[0067] When installing the external keyboard 22 of the present invention, the base 2 is rotated to the back of the screen 1 to act as a bracket. At this time, one side of the base 2 that fixes the keyboard 22 is in contact with the desktop. Since the upper surface of the keyboard 22 is slightly lower than the upper surface of the base 2, the keyboard 22 will not be damaged by friction with the desktop, but the upper surface of the edge of the base 2 may be worn. In order to protect the surface of the base 2, rubber strips 24 are now fixedly connected to the edges of the upper surfaces on both sides of the base 2. When this surface of the base 2 acts as a bracket, this surface can be slightly padded to avoid direct scratches. The friction between the rubber strip 24 and the desktop is relatively large, which can prevent the body from slipping sideways when it is placed. The rubber strip 24 itself has a certain elasticity, which can play a buffering role when the screen 1 and the base 2 are fitted and closed, to avoid excessive collision force and scratches on the screen 1.

[0068] Working principle: The wireless connection type network computer of the present invention comprises a main body screen 1 and a base 2, which are connected by a hinge 3 and can rotate around each other through the hinge 3. A square keyboard slot 21 is provided on the upper surface of the base 2, and the side away from the hinge 3 penetrates the side of the base 2 and communicates with the outside, so that the sliding device 4 located inside it can slide out to the outside through the side, and the keyboard 22 is fixed on the surface of the sliding device 4. The sliding device 4 in the present invention is used to adjust the position of the keyboard 22 thereon, and it mainly comprises a sliding plate 41, a side sliding groove 42 and a side sliding block 43. There are two side sliding grooves 42, which are consistent in horizontal height and parallel to each other, and are provided on the side walls on both sides of the keyboard slot 21, and they are used to limit the sliding of the sliding plate 41. The sliding plate 41 is a sliding main body, which is located in the keyboard slot 21, and the keyboard 22 is arranged on it, so that when it slides relative to the keyboard slot 21, its sliding direction is always The side slide blocks 43 are parallel to the side walls of the keyboard slot 21 and do not separate from the keyboard slot 21. Therefore, side slide blocks 43 are fixed on both sides of the plate body, which are located in the side slide slots 42 and have a thickness slightly smaller than that of the side slide slots 42. In this way, it can slide while ensuring that it does not separate from the side slide slots 42. When the side slide blocks 43 are located at the top of the side slide slots 42 close to the hinge 3, the sliding plate 41 is completely located in the keyboard slot 21, and the plate edge away from the hinge 3 is flush with the side edge of the base 2 at that location. When the side slide blocks 43 are located at the top of the side slide slots 42 away from the hinge 3, this is the maximum sliding distance of the sliding plate 41, and also the maximum position of the keyboard 22. In this way, it can be prevented from sliding too far, causing it to fall off relative to the base 2 and causing damage to the keyboard 22. The device can realize the change of the position of the keyboard 22, thereby adapting to the different differences in the position requirements of different users for the keyboard 22 and improving the user experience.
