[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. The term "plurality" refers to two or more, unless otherwise expressly defined. Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art. To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] In the related art, a touchpad is provided on the keyboard of an electronic device such as a laptop or tablet computer, and the touchpad is at least partially embedded in the shell of the keyboard. A mounting base is provided at the bottom of the touchpad, and the mounting base is connected to the shell. For example, the mounting base can be a screw-locking base, the touchpad is connected to the screw-locking base, and the screw-locking base is connected to the keyboard shell. During the production and manufacturing process of the keyboard, there will be assembly deviations between the touchpad and the mounting base, and there will be assembly deviations between the mounting base and the shell. In addition, there will be errors in the openings on the covering parts (such as leather) on the shell during production. These errors are manifested in the appearance of the keyboard as uneven gaps between the multiple edges of the touchpad and the openings of the covering parts, which affects the refinement of the keyboard appearance and the customer's experience.

[0042] The exemplary embodiment of the present disclosure first provides a mounting fixture 100 for a keyboard, such as Figure 1 As shown, the keyboard includes a touch panel 220 and a housing 210, and the housing 210 is provided with a mounting portion 201 for mounting the touch panel 220. Figure 2 and Figure 3 As shown, the mounting fixture 100 includes a fixture body 10, on which a receiving portion 13 and a positioning portion are provided. The receiving portion 13 is used to receive the touchpad 220 of the keyboard, and the positioning portion is used to cooperate with the mounting portion 201 on the shell 210 to achieve the positioning of the fixture body 10.

[0043] The mounting jig 100 for a keyboard provided in an embodiment of the present disclosure includes a jig body 10. The jig body 10 is provided with a receiving portion 13 and a positioning portion. The receiving portion 13 receives the touchpad 220 of the keyboard. The positioning portion cooperates with the mounting portion 201 on the shell 210 to realize the positioning of the jig body 10. The touchpad 220 is positioned by the jig body 10 so that the touchpad 220 can be located at a preset position of the mounting portion 201 on the shell 210, thereby reducing the position deviation of the touchpad 220 on the keyboard, improving the installation accuracy of the touchpad 220, and thereby improving the appearance refinement of the keyboard. In addition, installing the touchpad 220 by using the mounting jig 100 is simple and convenient, which can improve the efficiency of keyboard production and manufacturing, thereby saving costs.

[0044] The following describes the keyboard mounting fixture 100 provided by the present disclosure through multiple embodiments:

[0045] In some embodiments, the receiving portion 13 on the fixture body 10 is a receiving groove. When the touchpad 220 is installed, the touchpad 220 is embedded in the fixture body 10, and the side frame of the receiving groove surrounds the touchpad 220. The side frame of the receiving groove is used to position the touchpad 220, so that the touchpad 220 can be accurately placed in the installation position, avoiding the position shift of the touchpad 220 due to installation and manufacturing errors.

[0046] The fixture body 10 may include a top plate 11 and a positioning frame 12. The positioning frame 12 and the top plate 11 are connected to form a receiving portion 13, and the side of the positioning frame 12 facing away from the receiving portion 13 forms a positioning portion. When the touchpad 220 is located in the receiving portion 13, the positioning frame 12 surrounds the touchpad 220. When the touchpad 220 is installed in the housing 210, the positioning frame 12 controls the relative position of the touchpad 220 and the housing 210, thereby reducing the deviation of the touchpad 220.

[0047] The fixture body 10 can be configured to mimic the touch panel 220. For example, if the touch panel 220 is a rectangular parallelepiped or a substantially rectangular parallelepiped structure, the fixture body 10 can also be a rectangular parallelepiped or a substantially rectangular parallelepiped structure. Alternatively, if the touch panel 220 is a circular or a substantially circular structure, the fixture body 10 can also be a circular or a substantially circular structure.

[0048] When the touch panel 220 is a polygonal structure, the positioning frame 12 includes multiple positioning plates, and the positioning plates correspond to the sides of the touch panel 220 one by one. The corresponding positioning plates are parallel to the sides of the touch panel 220, and the sides of the touch panel are the surfaces on the touch panel that are connected to the touch surface.

[0049] For example, the positioning frame 12 is a rectangular ring, and the positioning frame 12 includes a first positioning plate 121, a second positioning plate 122, a third positioning plate 123 and a fourth positioning plate 124. The first positioning plate 121 is connected to the top plate 11, and the side of the first positioning plate 121 facing away from the accommodating portion 13 forms a first side positioning structure; the second positioning plate 122 is connected to the top plate 11, and the side of the second positioning plate 122 facing away from the accommodating portion 13 forms a second side positioning structure; the third positioning plate 123 is connected to the top plate 11, and the side of the third positioning plate 123 facing away from the accommodating portion 13 forms a third side positioning structure; the fourth positioning plate 124 is connected to the top plate 11, and the side of the fourth positioning plate 124 facing away from the accommodating portion 13 forms a fourth side positioning structure.

[0050] In one feasible embodiment, the first positioning plate 121, the third positioning plate 123, the second positioning plate 122, and the fourth positioning plate 124 are connected end to end to form a rectangular frame. That is, the first positioning plate 121 and the second positioning plate 122 are arranged opposite each other, the ends of the third positioning plate 123 are connected to the first positioning plate 121 and the second positioning plate 122, respectively, and the ends of the fourth positioning plate 124 are connected to the first positioning plate 121 and the second positioning plate 122, respectively.

[0051] The top plate 11 is a rectangular plate having a first edge, a second edge, a third edge, and a fourth edge. A first positioning plate 121 is provided at the first edge, and the first positioning plate 121 extends from one end of the first edge to the other end of the first edge. A second positioning plate 122 is provided at the second edge, and the second positioning plate 122 extends from one end of the second edge to the other end of the second edge. A third positioning plate 123 is provided at the third edge, and the third positioning plate 123 extends from one end of the third edge to the other end of the third edge. A fourth positioning plate 124 is provided at the fourth edge, and the fourth positioning plate 124 extends from one end of the fourth edge to the other end of the fourth edge.

[0052] In other feasible embodiments, there may also be gaps between the first positioning plate 121, the second positioning plate 122, the third positioning plate 123 and the fourth positioning plate 124. For example, the first positioning plate 121 is provided at the first edge of the top plate 11, and the length of the first positioning plate 121 is less than the length of the first edge. The second positioning plate 122 is provided at the second edge of the top plate 11, and the length of the second positioning plate 122 is less than the length of the second edge. The third positioning plate 123 is provided at the third edge of the top plate 11, and the length of the third positioning plate 123 is less than the length of the third edge. The fourth positioning plate 124 is provided at the fourth edge of the top plate 11, and the length of the fourth positioning plate 124 is less than the length of the fourth edge.

[0053] The jig body 10 can be an integrally formed structure, that is, the top plate 11 and the positioning frame 12 are integrally formed. For example, the jig body 10 can be formed by casting or cutting. Alternatively, the jig body 10 can be a split-molded structure, for example, the top plate 11 and the positioning frame 12 are connected by welding or adhesive.

[0054] To ensure that the distances between the touch panels 220 and the opening (mounting portion 201) of the housing 210 are consistent during installation, the positioning frame 12 has the same thickness at all locations. For example, the first positioning plate 121, the second positioning plate 122, the third positioning plate 123, and the fourth positioning plate 124 have the same thickness.

[0055] For example, the thickness of the first positioning plate 121 is 0.22 mm-0.24 mm, the thickness of the second positioning plate 122 is 0.22 mm-0.24 mm, the thickness of the third positioning plate 123 is 0.22 mm-0.24 mm, and the thickness of the fourth positioning plate 124 is 0.22 mm-0.24 mm.

[0056] The side of the positioning frame 12 facing away from the accommodating portion 13 forms a positioning portion, which cooperates with the notch (mounting portion 201) on the housing 210 to position the touch panel 220. The side of the positioning frame 12 facing away from the accommodating portion 13 is tightly fitted with the side wall of the notch on the housing 210 (zero fit).

[0057] For example, the first side positioning structure, the second side positioning structure, the third side positioning structure and the fourth side positioning structure form a positioning portion. The first side positioning structure is a plane, the second side positioning structure is a plane, the third side positioning structure is a plane, and the fourth side positioning structure is a plane.

[0058] The fixture body 10 is configured so that when the touchpad 220 is located in the accommodating portion 13, the gap between the sidewalls of the accommodating portion 13 and the sidewalls of the touchpad 220 is less than or equal to 0.02 mm. In other words, when the touchpad 220 is located in the accommodating portion 13, the maximum gap between the outer edge of the touchpad 220 and the positioning frame 12 is 0.02 mm.

[0059] like Figure 4 and Figure 5 As shown, by setting the gap between the jig body 10 and the housing 210 to zero, and setting the gap between the touchpad 220 and the jig body 10 to be less than or equal to 0.02 mm, precise positioning of the touchpad 220 is achieved. This overcomes the assembly gaps between the touchpad 220 and the mounting base 230, the assembly gaps between the mounting base 230 and the housing 210, and the errors in the cover opening, allowing the touchpad 220 to be centered within the cover opening, and the gap between the touchpad 220 and the cover to be uniform.

[0060] When installing the touchpad 220, the clearance between the touchpad 220 and the opening in the housing 210 is designed to be L1. The openings in the mounting jig 100 and the housing 210 are set to zero, the thickness of the positioning frame 12 is set to L2, and the clearance between the touchpad 220 and the positioning frame 12 is set to L3, where the sum of L2 and L3 is configured to be L1. For example, the clearance between the touchpad 220 and the opening in the housing 210 is designed to be 0.25mm, the openings in the mounting jig 100 and the housing 210 are set to zero, the thickness of the positioning frame 12 is set to 0.23mm, and the clearance between the touchpad 220 and the positioning frame 12 is set to 0.02mm.

[0061] In related art, in the touch module, the assembly offset between the touchpad 220 and the screw-locking base plate is 0.1mm, the assembly gap between the screw-locking base plate and the plastic housing 211 is 0.05mm, and the PU leather touchpad 220 opening punching tolerance is 0.05mm. The above cumulative offset is 0.2mm, and the single-sided design gap of the touchpad 220 is 0.25mm, so uneven gaps are very likely to occur after assembly. In the embodiment of the present disclosure, the installation fixture 100 for the keyboard can avoid the position offset of the touchpad 220, so that the touchpad 220 is set in the center.

[0062] In some embodiments, the jig body 10 is provided with a disassembly portion protruding from the surface of the jig body 10. The disassembly portion is used to facilitate installation and removal of the jig 100 from the mounting portion 201 of the housing 210. For example, when the touchpad 220 is manually installed, the disassembly portion may be a grip. When the touchpad 220 is installed by a robot, the disassembly portion may be a gripping portion of the robot.

[0063] In the embodiment of the present disclosure, the keyboard can be a separate keyboard, a laptop keyboard, or a keyboard of a protective cover used in conjunction with a tablet computer. Figure 6 As shown, a touch panel 220 is provided on the keyboard, and the touch panel 220 is used to enable the keyboard to interact with the user through touch.

[0064] The touch panel 220 in the disclosed embodiments includes at least a cover plate of the touch module (the outermost plate of the touch panel 220). For example, the touch panel 220 may include a cover layer (including a cover glass layer and a Mylar film layer covering the cover glass layer). Alternatively, the touch panel 220 may include a cover layer and a functional layer (a capacitive touch layer or a resistive touch layer).

[0065] The mounting jig 100 for a keyboard provided in an embodiment of the present disclosure includes a jig body 10. The jig body 10 is provided with a receiving portion 13 and a positioning portion. The receiving portion 13 receives the touchpad 220 of the keyboard. The positioning portion cooperates with the mounting portion 201 on the shell 210 to realize the positioning of the jig body 10. The touchpad 220 is positioned by the jig body 10 so that the touchpad 220 can be located at a preset position of the mounting portion 201 on the shell 210, thereby reducing the position deviation of the touchpad 220 on the keyboard, improving the installation accuracy of the touchpad 220, and thereby improving the appearance refinement of the keyboard. In addition, installing the touchpad 220 by using the mounting jig 100 is simple and convenient, which can improve the efficiency of keyboard production and manufacturing, thereby saving costs.

[0066] An exemplary embodiment of the present disclosure further provides a keyboard mounting structure, which includes: a mounting fixture 100 and a keyboard, wherein the keyboard includes a touchpad 220 and a shell member 210, the touchpad 220 is disposed in the accommodating portion 13, and a mounting portion 201 is disposed on the shell member 210, the mounting fixture 100 is disposed in the mounting portion 201, and the positioning portion of the mounting fixture 100 abuts against the mounting portion 201.

[0067] Among them, the installation fixture 100 includes a fixture body 10, and the fixture body 10 is provided with a receiving portion 13 and a positioning portion. The receiving portion 13 is used to receive the touch pad 220 of the keyboard, and the positioning portion is used to cooperate with the installation portion 201 on the shell part 210 to realize the positioning of the fixture body 10.

[0068] The keyboard mounting structure provided by the embodiment of the present disclosure includes a mounting jig 100 and a keyboard. In the mounting jig 100, a receiving portion 13 and a positioning portion are provided on the jig body 10. The receiving portion 13 receives the touchpad 220 of the keyboard. The positioning portion and the mounting portion 201 on the shell 210 cooperate to realize the positioning of the jig body 10. The touchpad 220 is positioned by the jig body 10 so that the touchpad 220 can be located at the preset position of the mounting portion 201 on the shell 210, reducing the position deviation of the touchpad 220 on the keyboard, improving the installation accuracy of the touchpad 220, and thereby improving the appearance of the keyboard. In addition, installing the touchpad 220 by using the mounting jig 100 is simple and convenient, which can improve the efficiency of keyboard production and manufacturing, thereby saving costs.

[0069] In the disclosed embodiments, the keyboard can be a standalone keyboard, a keyboard fixedly connected to an electronic device (e.g., a laptop keyboard), or a keyboard detachably connected to an electronic device (e.g., a keyboard in a protective case). The keyboard is provided with a touchpad 220, which is used to enable touch interaction between the keyboard and the user. The touchpad 220 in the disclosed embodiments includes at least a cover for the touch module (the outermost panel of the touchpad 220).

[0070] When the keyboard is a protective cover keyboard, the housing 210 includes a plastic housing 211 and a covering layer 212. The covering layer 212 covers the plastic housing 211, and the mounting fixture 100 abuts against the covering layer 212. For example, the covering layer 212 can be a leather covering layer 212.

[0071] For example, the protective keyboard case may include a connecting portion and a keyboard, wherein the connecting portion is configured to be detachably connected to the tablet computer. For example, the connecting portion may be provided with a snap-fit ​​structure, through which the protective keyboard case and the electronic device are connected. Alternatively, the connecting portion may be a magnetic connection structure, which is magnetically connected to the electronic device.

[0072] The keyboard includes a shell 210 and a touchpad 220. The shell 210 is provided with a mounting portion 201, which is an opening on the shell 210, and the touchpad 220 is installed in the opening. The shell 210 may include a plastic shell 211 and a covering layer 212. The plastic shell 211 forms the skeleton structure of the keyboard. The covering layer 212 covers the surface of the plastic shell 211. The covering layer 212 is used to protect the plastic shell 211 and the internal components, and the covering layer 212 can enhance the sophistication of the keyboard. A mounting base 230 may also be provided in the opening of the plastic shell 211. The mounting base 230 is connected to the plastic shell 211 (for example, by screws), and the touchpad 220 is connected to the mounting base 230 (for example, by screws or bonding).

[0073] It should be noted that the mounting structure of the keyboard provided in the embodiment of the present disclosure is an intermediate structure in the keyboard assembly process, and the keyboard product does not include the mounting fixture 100 for the keyboard.

[0074] For example, when the keyboard is installed, the touchpad 220 is located within the opening of the housing 210. The distance between the left edge of the touchpad 220 and the sidewall of the opening is S1, the distance between the right edge of the touchpad 220 and the sidewall of the opening is S2, the distance between the top edge of the touchpad 220 and the sidewall of the opening is S3, and the distance between the bottom edge of the touchpad 220 and the sidewall of the opening is S4. S1, S2, S3, and S4 in the technical solutions provided in the related art and the technical solutions provided in this application are shown in Table 1.

[0075] Table 1

[0076]

[0077] As can be seen from Table 1, when the touchpad 220 is installed using the technical solutions in the related art, the gaps between S1, S2, S3, and S4 are large, meaning that the touchpad 220 is poorly centered. However, when the touchpad 220 is installed using the technical solution provided in this application, S1, S2, S3, and S4 are more evenly spaced, and the touchpad 220 is more centered, meaning that the positional offset of the touchpad 220 is smaller.

[0078] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein.
