[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Please refer to Figures 1 to 5 As shown, in an embodiment of the utility model, a folding keyboard is provided, which includes a first main body portion 1, a second main body portion 2, and a first hinge structure 8. The first main body portion 1 and the second main body portion 2 are connected by the first hinge structure 8 to achieve unfolding or folding. A first shielding component 3 for shielding the folded portion between the first main body portion 1 and the second main body portion 2 is arranged between the first main body portion 1 and the second main body portion 2. The first shielding component 3 includes a first shielding member 31 and a second shielding member 32. The first shielding member 31 is hinged to the first main body portion 1, and the second shielding member 32 is slidably connected to the bottom surface of the second main body portion 2. The first shielding member 31 and the second shielding member 32 are hinged. When the first main body portion 1 and the second main body portion 2 are in a folded state, the second shielding member 32 is located between the first shielding member 31 and the end surface of the second main body portion 2, and the bottom surface of the second shielding member 32 is flush with the bottom surface of the second main body portion 2.

[0036] Specifically, the first main body 1 and the second main body 2 refer to components formed by dividing the keyboard, and both the first main body 1 and the second main body 2 may include a bottom shell and a panel covering each other, and a circuit board may be arranged between the bottom shell and the panel, wherein a plurality of mounting holes are arranged on the panel, and key components that can contact the circuit board are arranged in the mounting holes. The bottom surface of the first main body 1 and the second main body 2 refers to the surface where the first main body 1 or the second main body 2 contacts the support when the keyboard is in normal use, and the surface on the first main body 1 and the second main body 2 corresponding to the bottom surface is the front surface of the first main body 1 and the second main body 2.

[0037] The first hinge structure 8 is a component that can connect two objects and the two objects can rotate relative to each other along an axis. The first hinge structure 8 can adopt a single rotation axis structure or a multi-rotation axis structure, which can be freely selected according to the connection requirements of the mutually hinged objects, and will not be repeated here.

[0038] The first main body portion 1 and the second main body portion 2 are in an unfolded state, which means that the first main body portion 1 and the second main body portion 2 are parallel to each other and are in the same plane. At this time, the first main body portion 1 and the second main body portion 2 are in the same plane or approximately in the same plane; the first main body portion 1 and the second main body portion 2 are in a folded state, which means that the first main body portion 1 and the second main body portion 2 are stacked on each other, and at this time, the front face of the first main body portion 1 and the front face of the second main body portion 2 are close to each other.

[0039] The first shielding component 3 refers to a component that can shield other objects or structures. The first shielding member 31 and the second shielding member 32 both refer to components with a certain area. The first shielding member 31 and the second shielding member 32 can be in the shape of plates, blocks or strips. The first shielding member 31 is hinged to the first main body 1, which means that the first shielding member 31 is connected to the first main body 1 and can rotate relative to the first main body 1; the first shielding member 31 can be hinged to the first main body 1 through a hinge structure, a hinge shaft or a flexible component. The first shielding member 31 and the second shielding member 32 are connected, and both can rotate relative to the other; the first shielding member 31 and the second shielding member 32 are hinged through a hinge structure, a hinge shaft or a flexible component. The second shielding member 32 is slidably connected to the bottom surface of the second main body 2, which means that the second shielding member 32 can slide relative to the second main body 2, and its function is to prevent the first shielding assembly 3 from getting stuck when the first main body 1 and the second main body 2 rotate relative to each other. The bottom surface of the second shielding member 32 refers to the surface of the second shielding member 32 that is away from the first main body 1 when the first main body 1 and the second main body 2 are in the folded state, and the bottom surface of the second shielding member 32 can be a plane.

[0040] In the folding keyboard provided by the embodiment of the utility model, the first main body 1 and the second main body 2 are connected by a first hinge structure 8 to realize mutual expansion or folding of the two. A first shielding component 3 is arranged between the first main body 1 and the second main body 2, which is used to shield the folding structure of the first main body 1 and the second main body 2 after folding, so that the appearance of the folded keyboard is more beautiful. The first shielding component 3 includes a first shielding member 31 and a second shielding member 32, the first shielding member 31 is hinged to the first main body 1, and the second shielding member 32 is slidably connected to the bottom surface of the second main body 2. The first shielding member 31 and the second shielding member 32 are hinged, so that the first shielding member 31 and the second shielding member 32 can both move during the relative rotation of the first main body 1 and the second main body 2, so as to avoid the existence of the first shielding member 31 and the second shielding member 32 affecting the expansion and folding of the first main body 1 and the second main body 2. Compared with the folding keyboard in the prior art, when the first main body 1 and the second main body 2 are in a folded state, the second covering member 32 is located between the first covering member 31 and the end surface of the second main body 2, and the bottom surface of the second covering member 32 is flush with the bottom surface of the second main body 2, instead of covering the second covering member 32 on the bottom surface of the second main body 2. This reduces the size in the thickness direction after the first main body 1 and the second main body 2 are folded to a certain extent, reduces the volume occupied by the keyboard after folding, and has a simple, practical and convenient structure.

[0041] It should be noted that the second main body 2 has a smooth edge close to the first main body 1, and its shape can be a straight line or a state close to a straight line. This can be achieved by reasonably selecting the split position of the entire keyboard.

[0042] In addition, since the first main body portion 1 and the second main body portion 2 themselves have a certain thickness, when the first main body portion 1 and the second main body portion 2 are connected and installed, the first hinge structure 8 can be installed between the first main body portion 1 and the second main body portion 2 near the front surface, and the first shielding component 3 can be installed between the first main body portion 1 and the second main body portion 2 near the bottom surface, so that the first shielding component 3 and the first hinge structure 8 are spaced apart along the thickness Z direction of the keyboard, thereby making the connection and mutual rotation of the first main body portion 1 and the second main body portion 2 more convenient.

[0043] In an alternative embodiment, see Figure 2When the first body part 1 and the second body part 2 are in the unfolded state, the bottom surface of the first body part 1 and the bottom surface of the second body part 2 are spaced apart from each other, and there is a height difference between the bottom surface of the first body part 1 and the bottom surface of the second body part 2, and the bottom surface of the first body part 1 is lower than the bottom surface of the second body part 2. In this way, when the first body part 1 and the second body part 2 are in the unfolded state, the existence of the above-mentioned height difference can provide space for the arrangement of the first shielding member 31 and the second shielding member 32, so that the bottom surfaces of the first shielding member 31 and the second shielding member 32 can overlap with the second body part 2, but the bottom surfaces of the first shielding member 31 and the second shielding member 32 are flush with the bottom surface of the first body part 1, so that the overall bottom surface of the folding keyboard can be more flat and smooth when the folding keyboard is in the unfolded state.

[0044] In one embodiment, see Figure 1 , Figure 4 and Figure 6 , a receiving groove 21 is also provided on the bottom surface of the second main body 2, a sliding member 33 is provided on the second shielding member 32, a first end of the sliding member 33 is connected to the edge of the second shielding member 32, a second end of the sliding member 33 is slidably connected to the receiving groove 21, and the receiving groove 21 is open at one end close to the second shielding member 32, so that the sliding member 33 can be recessed and received in the receiving groove 21 when the first main body 1 and the second main body 2 are in a folded state. Specifically, the receiving groove 21 refers to a groove structure with a certain receiving space, and the receiving groove 21 is arranged along the sliding direction of the second shielding member 32. The sliding member 33 refers to a component with a certain length, and a first end of the sliding member 33 is connected to the edge of the second shielding member 32, and a second end of the sliding member 33 is slidably connected to the receiving groove 21. Through the cooperation of the sliding member 33 and the receiving groove 21, the sliding connection between the second shielding member 32 and the second main body 2 can be more convenient and firm. Furthermore, by setting one end of the accommodating groove 21 close to the second covering member 32 to be open, when the second covering member 32 is located between the first covering member 31 and the second main body 2, the sliding member 33 can be recessed and accommodated in the accommodating groove 21, thereby preventing the upper surface of the sliding member 33 from protruding from the bottom surface of the second main body 2, thereby making the bottom surface of the keyboard smoother.

[0045] In one embodiment, see Figure 6, a first limiting portion 22 is provided on the inner wall of the receiving groove 21, and a second limiting portion 34 is provided on the second end of the sliding member 33, and the first limiting portion 22 is used to cooperate with the second limiting portion 34 to prevent the sliding member 33 from escaping from the receiving groove 21. Specifically, the first limiting portion 22 refers to a structure or component provided on the inner wall of the receiving groove 21, and the first limiting portion 22 is provided along the length direction of the receiving groove 21. Among them, the first limiting portion 22 can be a groove structure provided on the inner wall of the receiving groove 21; the first limiting portion 22 can also be a protruding structure provided on the inner wall of the receiving groove 21, and the second limiting portion 34 refers to a component provided on the side of the sliding member 33 facing the first limiting portion 22. When the first limiting portion 22 adopts a groove structure, the first limiting portion 22 can extend into the groove structure and limit the first limiting portion 22 by the side wall of the groove structure; when the first limiting portion 22 adopts a protrusion structure, the first limiting portion 22 can be staggered along the width direction of the accommodating groove 21 (that is, the keyboard width direction X), so that the second limiting portion 34 abuts against the side of the first limiting portion 22 to prevent the sliding member 33 from escaping from the accommodating groove 21.

[0046] In one embodiment, see Figure 6 The first limiting portion 22 includes a limiting convex strip 221 arranged along the length direction of the receiving groove 21, and the second limiting portion 34 includes a limiting protrusion 341 arranged on the sliding member 33. The limiting protrusion 221 is spaced from the bottom surface of the receiving groove 21 to form a limiting space for accommodating the limiting protrusion 341, and the limiting protrusion 341 is slidably arranged in the limiting space. Specifically, the limiting protrusion 221 refers to a component with a certain length, and the limiting protrusion 221 can be a block, a plate or a column, etc. The limiting protrusion 221 can be an integrally formed structure with the first main body 1; the limiting protrusion 221 can also be a separate structure with the first main body 1, and the limiting protrusion 221 is fixed to the inner wall of the receiving groove 21 by bonding, welding or fasteners. The limiting protrusion 341 refers to a component with a certain height, and the limiting protrusion 341 can be a block, a column or a plate, etc. The limiting convex strip 221 can be spaced apart from the bottom surface of the receiving groove 21 to form a limiting space for receiving the limiting protrusion 341. After the second end of the sliding member 33 is inserted into the receiving groove 21, at least a portion of the limiting protrusion 341 can be extended to the limiting space. Under the premise of not affecting the sliding of the sliding member 33, the blocking effect of the limiting convex strip 221 prevents the sliding member 33 and the limiting protrusion 341 from falling out of the receiving groove 21, thereby making the sliding of the sliding member 33 along the receiving groove 21 safer and more convenient.

[0047] In addition, if Figure 1As shown, the cross section of the limiting protrusion 341 can be circular, and the cross section of the limiting protrusion 341 refers to the cross section intercepted by a plane perpendicular to the height direction of the limiting protrusion 341. By setting the cross section of the limiting protrusion 341 to be circular, the contacting parts of the limiting protrusion 341 and the limiting convex strip 221 can be arc-shaped surfaces, reducing the contact area between the two, making the relative sliding between the limiting protrusion 341 and the limiting convex strip 221 more convenient.

[0048] In an alternative embodiment, see Figure 6 The limiting convex strip 221 is also provided with an avoidance notch, which can be provided at one end of the limiting convex strip 221 away from the first shielding member 31. When the sliding member 33 is installed, the limiting protrusion 341 is inserted into the interior of the accommodating groove 21 through the avoidance notch, making the installation of the sliding member 33 more convenient.

[0049] In one embodiment, see Figure 6 The limiting convex strip 221 is also provided with a positioning structure 23, which is used to fix the limiting protrusion 341 when the first main body 1 and the second main body 2 are in the unfolded state to prevent the sliding member 33 and the limiting protrusion 341 from moving. Specifically, the positioning structure 23 refers to a structure or component used to limit the limiting protrusion 341 after the limiting protrusion 341 slides to a specified position. Through the setting of the positioning structure 23, the position of the limiting protrusion 341 can be limited when the first main body 1 and the second main body 2 are unfolded, so as to prevent the first shielding plate and the second shielding plate from moving in a direction away from the second main body 2 under the action of their own gravity.

[0050] In one embodiment, see Figure 6 The positioning structure 23 includes a positioning groove 231, and the positioning groove 231 is located on the side of the limiting convex strip 221 close to the limiting protrusion 341. Specifically, the positioning groove 231 refers to a groove structure with a certain depth, and the positioning groove 231 is concavely arranged on the side of the limiting convex strip 221 close to the limiting protrusion 341. When the first main body 1 and the second main body 2 are unfolded, the limiting protrusion 341 also slides to the positioning groove 231 and can be inserted into the positioning groove 231, thereby limiting the limiting protrusion 341. When the first main body 1 and the second main body 2 need to be folded, only the sliding member 33 needs to be pushed to drive the limiting protrusion 341 to be removed from the positioning groove 231.

[0051] In one embodiment, see Figures 9 to 11, a shielding protrusion 311 is provided on the inner side of the first shielding member 31, and when the first main body 1 and the second main body 2 are in a folded state, the shielding protrusion 311 is used to shield the gap between the first shielding member 31 and the first main body 1 and the gap between the first shielding member 31 and the second main body 2, and when the first main body 1 and the second main body 2 are in an unfolded state, the shielding protrusion 311 is used to be accommodated in the accommodating groove 21. Specifically, the shielding protrusion 311 refers to a component with a certain height dimension, and the shielding protrusion 311 can be a block, a plate or a strip, and the shielding protrusion 311 can also be a combination of multiple shapes. The shielding protrusion 311 can be an integrally formed structure with the first shielding member 31, and the shielding protrusion 311 can also be an independent component, which is installed on the first shielding member 31 by welding, bonding or fixing with fasteners. By providing a shielding protrusion 311 on the inner side of the first shielding member 31, when the first main body 1 and the second main body 2 are in the folded state, the shielding protrusion 311 can shield the gap between the first shielding member 31 and the first main body 1 and the gap between the first shielding member 31 and the second main body 2, so that the appearance of the entire folded keyboard is more beautiful. At the same time, the position of the shielding protrusion 311 on the first shielding member 31 matches the position of the accommodating groove 21, so that when the first main body 1 and the second main body 2 are in the unfolded state, the shielding protrusion 311 can be inserted into the accommodating groove 21, so that the bottom surface of the entire folded keyboard is flatter after unfolding.

[0052] In one embodiment, see Figure 4 and Figure 5 The second shielding member 32 is provided with a pushing structure 4, which is used to move the second shielding member 32 in a direction away from the first main body 1 during the folding process between the first main body 1 and the second main body 2. Specifically, the second shielding member 32 can be moved in a direction away from the second main body 2 during the folding process between the first main body 1 and the second main body 2 by setting the pushing structure 4, so that the second shielding member 32 and the second main body 2 are misaligned along the length direction Y of the keyboard, thereby avoiding interference between the second shielding member 32 and the second main body 2 when the first main body 1 and the second main body 2 are folded together.

[0053] In one embodiment, see Figure 5The pushing structure 4 includes an extrusion protrusion 41 arranged on the second shielding member 32, and an extrusion sliding surface 42 is also arranged on the extrusion protrusion 41. During the mutual folding process of the first main body 1 and the second main body 2, the extrusion sliding surface 42 slides against the second main body 2 to move the second shielding member 32 away from the second main body 2. Specifically, the extrusion protrusion 41 refers to a component with a certain volume, and the extrusion protrusion 41 can be block-shaped, plate-shaped or column-shaped. The extrusion protrusion 41 can be an integrally formed structure with the second shielding member 32, and the extrusion protrusion 41 can also be fixed to the second shielding member 32 by welding. Adhesion or fasteners. The extrusion sliding surface 42 refers to a surface structure arranged on the extrusion protrusion 41, and the extrusion sliding surface 42 can be arranged at an angle with the thick bottom direction Z of the keyboard. In addition, a support protrusion that cooperates with the extrusion protrusion 41 can be arranged on the end face of the second main body 2, and the extrusion sliding surface 42 on the extrusion protrusion 41 can be against the support protrusion. The extrusion protrusion 41 can be in sliding contact with the second main body part 2 through the extrusion sliding surface 42. When the second shielding member 32 approaches the second main body part 2, the second shielding member 32 can be subjected to the extrusion force of the second main body part 2 through the setting of the extrusion protrusion 41 and the extrusion sliding surface 42, so that the second shielding member 32 can be moved away from the second main body part 2 to avoid interference between the second shielding member 32 and the second main body part 2.

[0054] In one embodiment, see Figure 1 and Figure 2 The folding keyboard also includes a first functional part 5 and a second hinge structure 9. The first functional part 5 is connected to the first main body 1 through the second hinge structure 9 to realize the mutual expansion or folding of the two, and a second shielding component 7 for shielding the rotating shaft structure between the first main body 1 and the first functional part 5 is also provided. Specifically, the first functional part 5 refers to a component that can play a certain function. The first functional part 5 can be a numeric keyboard or a touchpad. The second hinge structure 9 refers to a component that can connect two objects and the two objects can rotate relative to each other along an axis. The second hinge structure 9 can adopt the same structure as the first hinge structure 8, or it can adopt a different structure from the first hinge structure 8. The second shielding component 7 refers to a component that can shield other objects or structures. The structure of the second shielding component 7 can be the same as or different from the first shielding component 3. The first functional part 5 is hinged to the first main body 1 through the second hinge structure 9 and can be expanded or folded. The functionality of the keyboard is further increased by setting the first functional part 5, making the use of the folding keyboard more convenient.

[0055] It should be noted that when the structure of the second shielding component 7 is the same as that of the first shielding component 3, a matching accommodating groove, a first limiting portion and a positioning structure need to be provided on the bottom surface of the first functional part 5, and the working principle and effect of the second shielding component 7 are the same as those of the first shielding component 3.

[0056] In an alternative embodiment, see Figure 1 and Figure 2 The first functional part 5 and the second main body part 2 are respectively arranged at the two ends of the first main body part 1, and the rotation axis of the first functional part 5 and the rotation axis of the second main body part 2 are parallel to each other. When the folding keyboard is folded, the first functional part 5 and the second main body part 2 can be bent toward the first main body part 1, so that the shape of the folded keyboard is more beautiful and the volume after folding is reduced.

[0057] In one embodiment, see Figure 7 and Figure 8 , a second functional part 6 is provided on the first main body 1, and the second functional part 6 is movably connected to the bottom surface of the first main body 1. Specifically, the second functional part 6 refers to a component with certain functions, and the second functional part 6 can be a touchpad or other functional components. When the first functional part 5 adopts a numeric keypad, the second functional part 6 can adopt a touchpad to avoid duplication of functions between the second functional part 6 and the first functional part 5. The provision of the second functional part 6 further increases the functionality of the folding keyboard. The second functional part 6 is movably connected to the bottom surface of the first main body 1, which means that the edge of the second functional part 6 can be hinged to the bottom surface of the first main body 1, so that the second functional part 6 can be flipped and stored; the second functional part 6 can also be slidably installed on the bottom surface of the first main body 1, so that the second functional part 6 can be slidably stored and opened, making the storage of the second functional part 6 more convenient.

[0058] In an alternative embodiment, see Figure 8 , a receiving groove 11 for accommodating the second functional part 6 is also provided on the bottom surface of the first main body 1. When the second functional part 6 is received in the receiving groove 11, the side of the second functional part 6 facing away from the first main body 1 is flush with the bottom surface of the first main body 1. When the second functional part 6 is installed in a sliding connection manner, a slide rail structure can be provided between the edge of the second functional part 6 and the side wall of the receiving groove 11, so as to realize the sliding and pulling installation of the second functional part 6. The second functional part 6 is installed in a sliding and pulling manner. After the second functional part 6 slides into the receiving groove 11, the working surface (such as the touch surface) of the receiving groove 11 is set upward to avoid the working surface being exposed to the outside, thereby improving the protection of the working surface of the second functional part 6.

[0059] In addition, the second functional part 6 can also be hinged to the first main body part 1. For example, two coaxially arranged rotating shafts can be respectively arranged on both sides of the second functional part 6, and two hinge holes can be arranged on the inner wall of the storage groove 11. The hinged installation of the second functional part 6 can be achieved by cooperating between the rotating shaft and the hinge hole. Alternatively, two coaxially arranged hinge holes can be respectively arranged on both sides of the second functional part 6, and two rotating shafts can be arranged on the inner wall of the storage groove 11. The hinged installation of the second functional part 6 can be achieved by cooperating between the rotating shaft and the hinge hole. The hinged method is more cost-effective.

These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
