DETAILED DESCRIPTION

[0036] The technical scheme in the embodiment of the utility model will be clearly and completely described below by combining with the drawings in the embodiment of the utility model, obviously, the described embodiment is one kind of embodiment of the utility model, not all the embodiments of the utility model. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0037] Embodiment 1:

[0038] Please refer to Figures 1 to 6 The embodiment provides a keyboard shell structure, which comprises a bottom shell 1 and a pressing frame 2 covering the bottom shell 1, the pressing frame 2 is provided with at least one first clamping piece 3 at one end and at least one second clamping piece 5 at the other end, the bottom shell 1 is provided with a first clamping structure 4 corresponding to the number of the first clamping piece 3 and connected with the first clamping piece 3 at one end, and is provided with a second clamping structure 6 corresponding to the number of the second clamping piece 5 and connected with the second clamping piece 5 at the other end.

[0039] The first clamping piece 3 comprises a first mounting part 31 connected to one end of the pressing frame 2 and a first elastic clamping part 32 arranged at both ends of the first mounting part 31 and used for clamping connection with the first clamping structure 4, and the second clamping piece 5 comprises a second mounting part 51 connected to the other end of the pressing frame 2 and a second elastic clamping part 52 arranged at both ends of the second mounting part 51 and used for clamping connection with the second clamping structure 6.

[0040] The first mounting part 31 of the first clamping piece 3 is detachably connected to one end of the pressing frame 2, and the second mounting part 51 of the second clamping piece 5 is detachably connected to the other end of the pressing frame 2.

[0041] A first through hole 311 is formed in the middle of the first mounting part 31, a first placing groove 211 for placing the first mounting part 31 is formed in one end of the bottom of the pressing frame 2, a first threaded hole 212 is formed in the first placing groove 211, a first bolt 271 is inserted into the first through hole 311 of the first mounting part 31, the first mounting part 31 is tightly pressed against the first placing groove 211 by the first bolt 271 and is threadedly connected with the first threaded hole 212, a second through hole 511 is formed in the middle of the second mounting part 51, a second placing groove 221 for placing the second mounting part 51 is formed in the other end of the bottom of the pressing frame 2, a second threaded hole 222 is formed in the second placing groove 221, a second bolt 272 is inserted into the second through hole 511 of the second mounting part 51, the second mounting part 51 is tightly pressed against the second placing groove 221 by the second bolt 272 and is threadedly connected with the second threaded hole 222.

[0042] Through the above structure, when the first clamping piece 3 or the second clamping piece 5 is damaged, the user can conveniently take out and replace the first clamping piece 3 and the second clamping piece 5 from the pressing frame 2, thereby facilitating the user to maintain the keyboard shell structure and greatly improving the service life and use experience of the keyboard shell structure of the user.

[0043] The first elastic clamping part 32 and the second elastic clamping part 52 each comprise left and right elastic clamping blocks 7. The elastic clamping block 7 is arranged in a trapezoidal shape, and a micro convex clamping block 70 is arranged on one side of the trapezoidal shape of the elastic clamping block 7.

[0044] When the elastic blocks 7 of the first elastic locking portions 32 at both ends of the first locking member 3 are engaged with the first locking structure 4, the micro-protruding blocks 70 of the first elastic locking portions 32 can abut against the first locking structure 4 to prevent one end of the pressure frame 2 from loosening. Similarly, when the elastic blocks 7 of the second elastic locking portions 52 at both ends of the second locking member 5 are engaged with the second locking structure 6, the micro-protruding blocks 70 of the second elastic locking portions 52 can abut against the second locking structure 6 to prevent the other end of the pressure frame 2 from loosening. In addition, the elastic blocks 7 of the two first elastic locking portions 32 and the elastic blocks 7 of the second elastic locking portions 52 have a certain elasticity. When the user pulls out the pressure frame 2 by external force, the two first elastic locking portions 32 will retract inward, and the two second elastic locking portions 52 will retract inward, thereby causing the pressure frame 2 to detach from the bottom shell 1.

[0045] Furthermore, the first elastic latching part 32 has a first opening 700 between the two sides of the elastic latching strip, and the second elastic latching part 52 has a first opening 700 between the two sides of the elastic latching strip. The first opening 700 helps to reduce the weight of the keyboard shell structure and improve the elastic deformation capability.

[0046] The bottom shell 1 has a cover boss 18 on the top, the pressure frame 2 has a cover groove 28 on the bottom that covers the cover boss 18, and the inner walls of the pressure frame 2 have pressure frame arms 29 at both ends.

[0047] Furthermore, this embodiment 1 also has two implementation methods:

[0048] The first implementation method is (as shown in the appendix) Figure 5 As shown): The two ends of the mounting portion of the first snap-fit ​​3 and the two ends of the mounting portion of the second snap-fit ​​5 are not provided with the second downward extension portion 86.

[0049] The second implementation method is (as shown in the appendix) Figure 6 As shown): The two ends of the mounting portion of the first snap-fit ​​member 3 and the two ends of the mounting portion of the second snap-fit ​​member 5 are provided with second downward extension portions 86. The second downward extension portion 86 of the mounting portion of the first snap-fit ​​member 3 abuts against the side wall of the first snap-fit ​​structure 4 at one end of the bottom shell 1, and the second downward extension portion 86 of the mounting portion of the second snap-fit ​​member 5 abuts against the side wall of the second snap-fit ​​structure 6 at the other end of the bottom shell 1. That is, after the pressure frame 2 is covered on the bottom shell 1, the pressure frame 2 abuts against the inner sides of the bottom shell 1, which greatly improves the stability and firmness of the pressure frame 2 covering the bottom shell 1.

[0050] The advantages of the keyboard shell structure in this embodiment are:

[0051] 1. The first clamping part 3 on one end of the pressing frame 2 is clamped to the first clamping structure 4 on one end of the bottom shell 1, and the second clamping part 5 on the other end of the pressing frame 2 is clamped to the second clamping structure 6 on the other end of the bottom shell 1, which structure is convenient for disassembling the pressing frame 2 and the bottom shell 1.

[0052] 2. The first clamping part 3 and the second clamping part 5 are simple to install with the pressing frame 2, and at the same time, the first clamping part 3 and the second clamping part 5 are easy to disassemble from the pressing frame 2, which facilitates the user to replace the first clamping part 3 and the second clamping part 5, greatly improving the service life and use experience of the user's keyboard shell structure.

[0053] 3. The first elastic clamping part 32 and the second elastic clamping part 52 are clamped and connected to the bottom shell 1 through the left and right elastic clamping blocks 7, and the trapezoidal structure of the elastic clamping block 7 and the micro convex clamping block 70 are convenient for the quick disassembly of the pressing frame 2 and the bottom shell 1, and at the same time, the pressing frame 2 is very firm when it is closed on the bottom shell 1, and it will not be loose.

[0054] Embodiment 2:

[0055] Please refer to Figures 7 to 8 The difference between the keyboard shell structure of the present embodiment 2 and the embodiment 1 is only that the first elastic clamping part 32 of the first clamping part 3 and the second elastic clamping part 52 of the second clamping part 5 are not the same structure as the embodiment 1.

[0056] The two first elastic clamping parts 32 of the first clamping part 3 are respectively arranged in the shape of an elastic curved sheet 8 arranged oppositely and downward, and the two second elastic clamping parts 52 of the second clamping part 5 are respectively arranged in the shape of an elastic curved sheet 8 arranged oppositely and downward.

[0057] Among them, the elastic curved sheet shape 8 of the first elastic clamping part 32 of the first clamping part 3 is connected together with the first mounting part 31 through the first downward extension part 80, and the elastic curved sheet shape 8 of the second elastic clamping part 52 of the second clamping part 5 is connected together with the second mounting part 51 through the first downward extension part 80.

[0058] The keyboard shell structure of the present embodiment 2, in which the first clamping part 3 benefits from the use of the above-mentioned elastic curved sheet shape 8 of the first elastic clamping part 32, and the second clamping part 5 benefits from the use of the above-mentioned elastic curved sheet shape 8 of the second elastic clamping part 52, makes the pressing frame 2 and the bottom shell 1 more smooth and more smooth when they are closed and connected.

[0059] Further, the present embodiment 2 has two implementation ways:

[0060] The first implementation way is (as shown in the accompanying drawings) Figure 7As shown): The two ends of the mounting portion of the first snap-fit ​​3 and the two ends of the mounting portion of the second snap-fit ​​5 are not provided with the second downward extension portion 86.

[0061] The second implementation method is (as shown in the appendix) Figure 8 As shown): The two ends of the mounting portion of the first snap-fit ​​member 3 and the two ends of the mounting portion of the second snap-fit ​​member 5 are provided with second downward extension portions 86. The second downward extension portion 86 of the mounting portion of the first snap-fit ​​member 3 abuts against the side wall of the first snap-fit ​​structure 4 at one end of the bottom shell 1, and the second downward extension portion 86 of the mounting portion of the second snap-fit ​​member 5 abuts against the side wall of the second snap-fit ​​structure 6 at the other end of the bottom shell 1. That is, after the pressure frame 2 is covered on the bottom shell 1, the pressure frame 2 abuts against the inner sides of the bottom shell 1, which greatly improves the stability and firmness of the pressure frame 2 covering the bottom shell 1.

[0062] Example 3:

[0063] Please see Figures 9 to 11 The only difference between the keyboard shell structure of this embodiment 3 and that of embodiment 2 is that the first elastic snap-fit ​​part 32 of the first snap-fit ​​member 3 and the second elastic snap-fit ​​part 52 of the second snap-fit ​​member 5 of this embodiment 3 are modified based on embodiment 2.

[0064] That is, based on the structure of the first elastic snap-fit ​​portion 32 of the first snap-fit ​​member 3 and the second elastic snap-fit ​​portion 52 of the second snap-fit ​​member 5 in Embodiment 2, a second opening 85 is provided in the middle of the elastic bending piece shape 8 of the first elastic snap-fit ​​portion 32 of the first snap-fit ​​member 3 and the middle of the elastic bending piece shape 8 of the second elastic snap-fit ​​portion 52 of the second snap-fit ​​member 5.

[0065] The function of the second opening 85 is to reduce weight and improve elastic deformation capacity, so that the connection between the pressure frame 2 and the bottom shell 1 is smoother (when the two are closed, the elastic capacity of the first snap-fit ​​3 and the second snap-fit ​​5 is greater, making it easier to disassemble and assemble), and disassembly and assembly are smoother.

[0066] Furthermore, this embodiment 3 also has two implementation methods:

[0067] The first implementation method is (as shown in the appendix) Figure 9 As shown): The two ends of the mounting portion of the first snap-fit ​​3 and the two ends of the mounting portion of the second snap-fit ​​5 are not provided with the second downward extension portion 86.

[0068] The second implementation method is (as shown in the appendix) Figure 10 Or attached Figure 11As shown): The two ends of the mounting portion of the first snap-fit ​​member 3 and the two ends of the mounting portion of the second snap-fit ​​member 5 are provided with second downward extension portions 86. The second downward extension portion 86 of the mounting portion of the first snap-fit ​​member 3 abuts against the side wall of the first snap-fit ​​structure 4 at one end of the bottom shell 1, and the second downward extension portion 86 of the mounting portion of the second snap-fit ​​member 5 abuts against the side wall of the second snap-fit ​​structure 6 at the other end of the bottom shell 1. That is, after the pressure frame 2 is covered on the bottom shell 1, the pressure frame 2 abuts against the inner sides of the bottom shell 1, which greatly improves the stability and firmness of the pressure frame 2 covering the bottom shell 1.
