[0034] like Figure 1 As shown, the keyboard structure includes: a keyboard frame 12;

[0035] Bracket 2, bracket 2 is arranged on one side of keyboard frame 12;

[0036] A linkage rod 3, one end of which is hinged on the bracket 2;

[0037] A key rod 13, the middle part of which is correspondingly mounted on the keyboard frame 12 through a fulcrum, and one end of which extends to the bottom of the linkage rod 3;

[0038] The bracket 2 is provided with a first mutual inductance end 4 corresponding to the upper side of the linkage rod 3. Correspondingly, a drum wheel 6 is hingedly connected to the upper side of the linkage rod 3. The free end of the drum wheel 6 is provided with a second mutual inductance end 5 corresponding to the first mutual inductance end 4.

[0039] The other end of the key rod 13 is pressed to lift the linkage rod 3, wherein the key rod 13 extends downward near the hinge point of the linkage rod 3. The linkage rod 3 is affected by gravity and gives a certain resistance to the key rod 13, so that the pressing of the key rod 13 has a certain authenticity. In addition, as the key rod 13 drives the linkage rod 3 to rotate upward, the second mutual inductance end 5 on the drum wheel 6 and the first mutual inductance end 4 are intertwined and mutually inducted to simulate the actual touch of the piano, making the playing closer to the real piano and improving the player's playing experience.

[0040] In another optional embodiment of the present application, a clearance gap corresponding to the first mutual inductance end 4 is provided on the upper edge of the linkage rod, and the drum 6 is hinged on the upper edge of the clearance gap. The first mutual inductance end 4 is fixedly connected to the bracket 2 by a drum limit block 10 that can be extended into the clearance gap; the clearance gap gives the second mutual inductance end 5 a certain amount of space for extension, which can reduce the volume occupancy rate of the present application, make the structure more reasonable, and reduce the volume of the product.

[0041] In this embodiment, one end of the bracket 2 is fixedly connected to the keyboard frame 12, and the other end is bent toward the key rod 13. The lower side of the bend has a mounting groove corresponding to the linkage rod 3; one end of the linkage rod 3 is hinged in the mounting groove through a pin. Providing the mounting groove at the lower side of the bracket 2 can further save space. In addition, the mutual induction process of the first mutual induction end 4 and the second mutual induction end 5 occurs in the mounting groove, which prevents the drum wheel 6 from swinging left and right, thereby improving the accuracy of the touch.

[0042] In another optional embodiment of the present application, a smooth protrusion is provided at the lower edge of the linkage rod 3 near the hinged end, and the smooth protrusion extends downward from the lower edge of the bracket 2, and contacts the key rod 13 through the smooth protrusion, thereby reducing the friction between the key rod 13 and the linkage rod 3 during the pressing process. Correspondingly, a copper clip 8 corresponding to the smooth protrusion is provided on the key rod 13, and a linkage rod 3 felt core is provided at the smooth protrusion of the linkage rod 3 to reduce the contact area, increase the service life of the contact part, and avoid wear caused by repeated pressing.

[0043] In another optional embodiment of the present application, a pad 9 is provided between the end of the bracket 2 and the free end of the linkage rod 3; a pad 9 is provided between the free end of the linkage rod 3 and the key rod 13; a pad 9 corresponding to the key rod 13 is provided above the keyboard frame 12; and pads 9 corresponding to both sides of the drum wheel 6 are provided on the linkage rod 3. In summary, pads 9 are provided at each moving contact part of the structure, and the pads 9 are used to reduce the impact of each moving part during use, and the impact force is buffered to ensure smooth movement transition and no noise during use.

[0044] In this embodiment, the cushion block 9 can be made of sound-absorbing and buffering materials such as felt, sponge or rubber, and the specific shape depends on the installation position.

[0045] In another optional embodiment of the present application, the bracket 2 is fixedly connected to the side edge of the keyboard frame 12 through the connecting rail 1, wherein the connecting rail 1 is provided with a dovetail groove, and the dovetail groove extends along the length direction of the keyboard frame 12; the connecting rail 1 is fixedly connected to the keyboard frame 12 by screws or welding to ensure its stability;

[0046] The bottom of the bracket 2 is slidably assembled on the keyboard frame 12 through a tenon matched with the dovetail groove; the bracket 2 and the connecting rail 1 are slidably assembled through the dovetail groove and the tenon, which is convenient for installation and assembly and has high stability.

[0047] In another optional embodiment of the present application, the free end of the linkage rod 3 is detachably equipped with a counterweight 7. The linkage rod 3 is provided with a socket corresponding to the counterweight 7, and the counterweight 7 is installed on the linkage rod 3 by interference fit.

[0048] In another optional embodiment of the present application, the linkage rod 3 is connected to the bracket 2 via a buckle 11. The buckle 11 is a C-shaped structure, which is clamped on the pin from bottom to top. The structure is simple and easy to assemble.

[0049] In this embodiment, as a preference, the buckle 11 and the linkage rod 3 are integrally formed, and the linkage rod 3 is made of elastic plastic material.

[0050] In another optional embodiment of the present application, the first mutual inductance end 4 and the second mutual inductance end 5 are both magnetic blocks, and the magnetic poles on adjacent sides of the two repel each other, and the piano playing process is simulated by the repulsion between the first mutual inductance end 4 and the second mutual inductance end 5, wherein the magnetic blocks are correspondingly embedded in the drum wheel 6 or the drum wheel limit block 10 and are connected by interference fit.

[0051] In another optional embodiment of the present application, the end of the drum limit hole abuts against the linkage rod 3 to limit the maximum rotation angle of the linkage rod 3 to prevent the linkage rod 3 from rotating due to inertia, thereby ensuring the continuity of the pressing force of the key rod 13.

[0052] In another optional embodiment of the present application, a limiting pin is provided below the key rod 13 and passes downward through the keyboard frame 12 .

[0053] The present application also provides an electric piano keyboard with piano touch, comprising any one of the keyboard structures described above.

[0054] In summary, the present invention provides a keyboard structure and an electric piano keyboard with piano touch, in which a hinged linkage rod 3 is arranged, and by pressing the key rod 13, the free end of the linkage rod 3 is driven to rotate, thereby giving the key rod 13 a certain resistance to pressing, thereby solving the problem that the existing engineering plastics are light in weight and the keyboard playing touch is not good. In addition, during the rotation of the linkage rod 3, the first mutual inductance end 4 and the second mutual inductance end 5 are intertwined and mutually inducted to simulate the piano playing touch, giving the performer the most realistic playing experience.
