[0037] The following is the attached Figure 1 To Attachment Fig. 9 , describing the keyboard assembly supporting fixture of an embodiment of the utility model.

[0038] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, a keyboard assembly support fixture includes a fixture base plate 100 and a positioning structure 200 .

[0039] The fixture bottom plate 100 is used to support the keyboard; Figure 5 The positioning structure 200 includes a positioning plate 210, a first limiting member 220 and a second limiting member 130. The positioning plate 210 can be detachably mounted on the fixture base plate 100, and the positioning plate 210 has a first installation state and a second installation state compared to the fixture base plate 100; wherein the first limiting member 220 is eccentrically arranged on the positioning plate 210, and the position of the first limiting member 220 when the positioning plate 210 is in the first installation state is different from the position of the first limiting member 220 when the positioning plate 210 is in the second installation state.

[0040] The second limiting member 130 is fixed on the fixture base plate 100, and the sides of the first limiting member 220 and the second limiting member 130 are used to abut against the sides of the keyboard, and the first limiting member 220 and the second limiting member 130 enclose a keyboard fixing area, which is used to limit the keyboard.

[0041] It should be understood that in the keyboard assembly process, the keyboard needs to be stably placed on the jig base plate 100, and the keyboard needs to be fixed. The first limiter 220 and the second limiter 130 enclose a keyboard fixing area, and the top of the first limiter 220 protrudes from the positioning plate 210, and the second limiter 130 protrudes from the jig base plate 100. The sides of the first limiter 220 and the second limiter 130 are both in contact with the sides of the keyboard, so that the keyboard is fixed in the keyboard fixing area on the jig base plate 100.

[0042] Specifically, the shape of the keyboard fixing area is adapted to the shape of the keyboard. However, different types of keyboards have different sizes, so the size of the keyboard fixing area must also be changed to enable the fixture base plate 100 to adapt to keyboards of various sizes.

[0043] Compared with the jig base plate 100, the positioning plate 210 has a first installation state and a second installation state, and the position of the first stopper 220 when the positioning plate 210 is in the first installation state is different from the position of the first stopper 220 when the positioning plate 210 is in the second installation state. Therefore, when the positioning plate 210 switches between the first installation state and the second installation state, the position of the first stopper 220 set on the positioning plate 210 will change compared with the jig base plate 100, while the position of the second stopper 130 set on the jig base plate 100 remains unchanged, so that the size of the keyboard fixing area changes, so that the jig base plate 100 can adapt to keyboards of various sizes without changing the model of the jig base plate 100. The convenience of keyboard assembly is increased.

[0044] According to the keyboard assembly supporting fixture of some embodiments of the present invention, the cross section of the positioning plate 210 is a rotationally symmetrical figure, and the rotationally symmetrical center of the positioning plate 210 is at a different position from that of the first limiting member 220 .

[0045] Specifically, the cross-section of the positioning plate 210 can be a rotationally symmetrical center figure such as a circle, a square, or a rectangle. The rotationally symmetrical center of the positioning plate 210 is different from the position of the first position-limiting member 220. It should be understood that the rotationally symmetrical center of the positioning plate 210 and the position of the first position-limiting member 220 are both on the axis of symmetry of the positioning plate 210, and there is a certain distance between the rotationally symmetrical center of the positioning plate 210 and the position of the first position-limiting member 220. In this embodiment, the selected implementation method is that the cross-section of the positioning plate 210 is a rectangle, the first position-limiting member 220 is eccentrically arranged on the axis of symmetry of the positioning plate 210, and the axis of symmetry is parallel to the long side of the positioning plate 210, so that there is a distance between the rotationally symmetrical center of the positioning plate 210 and the position of the first position-limiting member 220. The first installation state of the positioning plate 210 is when the keyboard fixing area enclosed by the first limit member 220 and the second limit member 130 is larger in area. The positioning plate 210 is rotated 180° relative to the first installation state with the rotational symmetry center as the rotation center, which is the second installation state of the positioning plate 210. When the positioning plate 210 is in the second installation state, the keyboard fixing area formed is smaller than the keyboard fixing area when the positioning plate 210 is in the first installation state.

[0046] Reference Figure 3 and Figure 4 According to the keyboard assembly supporting jig of some embodiments of the present invention, a positioning groove 110 is provided on the jig bottom plate 100, and the positioning plate 210 can be placed in the positioning groove 110 in a first installation state or a second installation state.

[0047] It should be understood that the top surface of the positioning plate 210 is flush with the top surface of the jig bottom plate 100, so that the keyboard is stably fixed on the jig bottom plate 100 without tilting. Therefore, a positioning groove 110 is provided on the jig bottom plate 100, and when the positioning plate 210 is placed in the positioning groove 110 in the first installation state or the second installation state, the top surface of the positioning plate 210 is flush with the top surface of the jig bottom plate 100, ensuring the bearing effect of the jig bottom plate 100 on the keyboard, and facilitating the assembly of the keyboard by the assembly equipment.

[0048] Reference Figures 3 to 5 According to the keyboard assembly supporting jig of some embodiments of the present invention, a first fixing hole 211 is opened on the positioning plate 210, and a second fixing hole 111 is opened on the bottom wall of the positioning groove 110. The first fixing hole 211 is connected to the second fixing hole 111, and the first fixing hole 211 and the second fixing hole 111 are used to pass through the connecting piece to connect the jig bottom plate 100 and the positioning plate 210.

[0049] It should be understood that the connecting member passes through the first fixing hole 211 and the second fixing hole 111 to fix the positioning plate 210 in the positioning groove 110, thereby achieving the effect of fixing the positioning plate 210 on the fixture base plate 100. At the same time, the positioning plate 210 needs to be detachably connected to the bottom wall of the positioning groove 110, so that the positioning plate 210 can be changed from being fixed in the positioning groove 110 in the first installation state to being fixed in the positioning groove 110 in the second installation state. The embodiments that the connecting member can adopt include but are not limited to positioning pins and bolts.

[0050] Reference Figure 4 According to the keyboard assembly supporting fixture of some embodiments of the present invention, a through groove 120 is opened in the middle of the bottom wall of the positioning groove 110 , and the through groove 120 passes through the bottom wall of the positioning groove 110 .

[0051] It should be noted that when the positioning plate 210 is changed from being fixed in the positioning groove 110 in the first installation state to being fixed in the positioning groove 110 in the second installation state, it is necessary to first remove the connecting piece, take out the positioning plate 210, and then rotate the positioning plate 210 180° and fix it in the positioning groove 110 in the second installation state. A through groove 120 is opened in the middle part of the bottom wall of the positioning groove 110, which can facilitate the removal of the positioning plate 210 from the positioning groove 110.

[0052] Reference Figure 3 and Figure 5 According to the keyboard assembly supporting fixture of some embodiments of the present invention, a fixing block 240 is arranged on the positioning plate 210, and the position of the fixing block 240 corresponds to the position of the first limiting member 220, and the first limiting member 220 is partially embedded in the fixing block 240 and the positioning plate 210, and the fixing block 240 is detachably arranged in the through groove 120.

[0053] It should be noted that the positioning plate 210 and the fixing block 240 are integrally formed, and the fixing block 240 has a certain thickness. The fixing block 240 is conducive to the first limiting member 220 being stably installed on the positioning plate 210, so the position of the fixing block 240 corresponds to the position of the first limiting member 220, and the first limiting member 220 is partially embedded in the fixing block 240 and the positioning plate 210. At the same time, the positioning plate 210 needs to be disassembled, and when disassembling, the fixing block 240 is pushed out of the through slot 120, and the positioning plate 210 can be pushed out of the positioning slot 110.

[0054] Reference Figure 6 and Figure 8 According to the keyboard assembly supporting jig of some embodiments of the present invention, the first limiting member 220 includes a first base 221 and a first lifting boss 222, the first lifting boss 222 is liftably arranged on the first base 221, the first base 221 is connected to the positioning plate 210, wherein the side of the first lifting boss 222 is used to abut against the side of the keyboard, and when the top of the first lifting boss 222 is subjected to force, it can descend relative to the jig bottom plate 100.

[0055] Specifically, in this embodiment, the first base 221 is connected to the positioning plate 210, and the first lifting boss 222 is escalably disposed on the first base 221. The first lifting boss 222 is tangent to the side of the keyboard so that the side of the first lifting boss 222 abuts against the side of the keyboard to achieve a fixing effect on the keyboard. In other embodiments, the side of the first lifting boss 222 overlaps the side of the keyboard to achieve a fixing effect.

[0056] It should be understood that during improper operation, the back and front of the keyboard may come into contact with the first lifting boss 222. In order to prevent the first lifting boss 222 from damaging the keyboard, the first lifting boss 222 is liftably arranged on the first base 221, and when the top of the first lifting boss 222 is subjected to force, it can descend relative to the fixture bottom plate 100 to protect the keyboard.

[0057] According to the keyboard assembly supporting fixture of some embodiments of the present invention, the first limiting member 220 also includes a first elastic member 224, a first installation cavity 223 is formed inside the first base 221, a first lifting boss 222 passes through the first installation cavity 223, and the top end of the first lifting boss 222 protrudes from the first installation cavity 223, and the first elastic member 224 is arranged between the bottom end of the first lifting boss 222 and the bottom wall of the first installation cavity 223.

[0058] It should be understood that when the top end of the first lifting boss 222 is subjected to force, the first lifting boss 222 drops in the direction close to the bottom wall of the first mounting cavity 223 to protect the keyboard. When the first lifting boss 222 is not subjected to force, the first lifting boss 222 should rebound to its initial position and maintain the top end of the first lifting boss 222 protruding out of the first mounting cavity 223 to achieve abutment and fixing effect on the side of the keyboard. Therefore, a first elastic member 224 is arranged between the bottom end of the first lifting boss 222 and the bottom wall of the first mounting cavity 223 to provide a rebound effect for the first lifting boss 222.

[0059] Reference Figure 7 and Fig. 9 According to the keyboard assembly supporting jig of some embodiments of the present invention, the second limiting member 130 includes a second base 131 and a second lifting boss 132, and the second lifting boss 132 is liftably arranged on the second base 131, and the second base 131 is connected to the jig bottom plate 100, wherein the side of the second lifting boss 132 is used to abut against the side of the keyboard, and when the top of the second lifting boss 132 is subjected to force, it can descend relative to the jig bottom plate 100.

[0060] It should be understood that the second stopper 130 is fixed on the jig bottom plate 100, and the second base 131 is connected to the jig bottom plate 100. The structure of the second base 131 is the same as that of the first stopper 220, and the function of the second stopper 130 is also the same as that of the first stopper 220. The back and front of the keyboard may contact the second lifting boss 132. In order to prevent the second lifting boss 132 from damaging the keyboard, the first lifting boss 222 is movably arranged on the second base 131, and when the top of the second lifting boss 132 is subjected to force, it can be lowered relative to the jig bottom plate 100 to protect the keyboard.

[0061] According to the keyboard assembly supporting fixture of some embodiments of the present invention, the second limiting member 130 also includes a second elastic member 134, a second installation cavity 133 is formed inside the second base 131, a second lifting boss 132 passes through the second installation cavity 133, and the top end of the second lifting boss 132 protrudes from the second installation cavity 133, and the second elastic member 134 is arranged between the bottom end of the second lifting boss 132 and the bottom wall of the second installation cavity 133.

[0062] It should be understood that when the top end of the second lifting boss 132 is subjected to force, the second lifting boss 132 drops in the direction close to the bottom wall of the second mounting cavity 133 to protect the keyboard. When the second lifting boss 132 is not subjected to force, the second lifting boss 132 should rebound to its initial position and maintain the top end of the second lifting boss 132 protruding out of the second mounting cavity 133 to achieve abutment and fixing effect on the side of the keyboard. Therefore, a second elastic member 134 is arranged between the bottom end of the second lifting boss 132 and the bottom wall of the second mounting cavity 133 to provide a rebound effect for the second lifting boss 132.

[0063] In addition, refer to Figure 1 and Figure 2 In order to conveniently determine whether the positioning plate 210 is placed in the positioning groove 110 in the first installation state or the second installation state, a marking member 230 is eccentrically arranged on the positioning plate 210.
