Description

Technical Field

[0001] This utility model relates to an electronic keyboard, and more particularly to a portable electronic keyboard with an enhanced rigidity structure. Background Technology

[0002] As a common keyboard instrument, the electronic keyboard is widely used in home entertainment, music teaching, and stage performances.

[0003] Existing portable electronic keyboards, due to their lightweight design, meet users' needs for carrying them around, but also face the problem of insufficient rigidity in the body structure. Traditional electronic keyboards mostly use ABS engineering plastic or thin-walled metal frames as the main support structure. Although this reduces the overall weight, it is prone to structural deformation due to external impacts (such as collisions and squeezing) during transportation or frequent movement. For example, the keyboard support area in the middle of the body is relatively long and lacks lateral reinforcement design, making it prone to bending and deformation in bumpy environments. Long-term use may cause key contact misalignment or circuit board desoldering.

[0004] Current solutions (such as adding a hard case or external protective case) can alleviate some of the problems, but they significantly increase the carrying volume and do not fundamentally improve the instrument's resistance to deformation. Utility Model Content

[0005] Therefore, it is necessary to provide a portable electronic keyboard with an enhanced rigidity structure to address the shortcomings of existing technologies.

[0006] A portable electronic keyboard with a reinforced rigid structure includes a keyboard body, a support base, and a frame. The support base is generally I-shaped and includes two positioning sections and a connecting section connecting the two positioning sections. A support surface is formed at the bottom of the support base. The keyboard body includes a bottom shell, and the bottom shell is also provided with a plurality of first assembly slots.

[0028] Please see Figures 1 to 7 This utility model provides a portable electronic keyboard with an enhanced rigidity structure, including a keyboard body 10, a music stand 20, a support base 30 and a frame 40. The support base 30 and the frame 40 are fixedly installed on the keyboard body 10, and the music stand 20 can be freely installed and removed from the keyboard body 10.

[0029] The support base 30 is generally H-shaped and includes two positioning sections 31 and a connecting section 32 connecting the two positioning sections 31. The bottom of the support base 30 forms a support surface for supporting the piano body 10 when it is placed alone on the table. The support base 30 has a first locking protrusion 311 and a positioning post 312 protruding from the upper end face of the positioning section 31. The first locking protrusion 311 has a first fixing hole 313 extending downward from the upper end face of the locking protrusion, and the first locking protrusion 311 has an internal thread on the hole wall of the first fixing hole 313. Furthermore, the support base 30 has a second locking protrusion 321 protruding from the middle of the upper end face of the connecting section 32. The second locking protrusion 321 has a second fixing hole 322, which extends downward from the upper end face of the second locking protrusion 321. The second locking protrusion 321 has an internal thread on the hole wall of the second fixing hole 322. In this embodiment, the first locking protrusion of the positioning section 31 is distributed on both sides of the positioning section 31. There are two support bases 30, which are located on both sides of the bottom of the piano body 10.

[0030] The main body 10 of the instrument includes a top shell 11 and a bottom shell 12. The bottom of the bottom shell 12 has two sets of positioning holes 124, which are respectively fitted into two support bases 30. Specifically, each set of positioning holes 124 includes a first positioning hole 121, a second positioning hole 122, and a third positioning hole 123, which correspond to a first locking protrusion 311, a positioning post 312, and a second locking protrusion 321, respectively. In addition, the bottom shell 12 also has several first assembly grooves 125 and several second assembly grooves 126. The first assembly grooves 125 are located at the bottom of the bottom shell 12, and their internal space extends along the left-right direction of the main body 10. The second assembly grooves 126 are located on the side of the bottom shell 12 facing away from the bottom surface.

[0031] The frame 40 includes a plurality of first reinforcing plates 41 and a plurality of second reinforcing plates 42, wherein the first reinforcing plates 41 and the second reinforcing plates 42 are both arranged in the form of long strips.

[0032] During assembly, the connecting section 32 of the support base 30 is installed on the piano body 10 along the front-back direction, and the first reinforcing plate 41 is installed on the piano body 10 along the left-right direction. The first reinforcing plate 41 corresponds one-to-one with the first assembly groove 125 and is installed in the first assembly groove 125. The second reinforcing plate 42 corresponds one-to-one with the second assembly groove 126 and is installed in the second assembly groove 126. This utility model also includes several fixing members, which pass through the second reinforcing plate 42 and are installed on the bottom shell 12.

[0033] The two support bases 30 are respectively installed in conjunction with the two sets of positioning holes 124. During installation, the first locking protrusion 311, the positioning post 312 and the second locking protrusion 321 of the support base 30 are respectively inserted into the first positioning hole 121, the second positioning hole 122 and the third positioning hole 123. The fixing member passes through the bottom shell 12 and is locked and fixed with the first fixing hole 313 and the second fixing hole 322. The connecting section 32 of the support base 30 is attached to the bottom surface of the bottom shell 12 and limits the first reinforcing plate 41.

[0034] The music stand 20 includes a main body 21 and two prongs 22 connected to the bottom of the main body 21. The main body 21 is generally L-shaped, and the prongs 22 are tilted backward. The piano body 10 has a vertically downward extending insertion hole 13 located on the rear side of the upper surface of the piano body 10. When the music stand 20 is installed on the piano body 10, the prongs 22 are inserted into the insertion hole 13. Because the prongs 22 are tilted backward on the main body 21, after the music stand 20 is installed, the main body 21 tilts backward, causing the sheet music placed on the main body 21 to also tilt backward, making it easier for the user to read the music. When it is necessary to remove the music stand 20 from the piano body 10, simply slide the music stand 20 to disengage the prongs 22 from the insertion hole 13 on the piano body 10.

[0035] The beneficial effects of this portable electronic keyboard with an enhanced rigidity structure are as follows: by setting a frame 40 and a support base 30, and setting a first reinforcing plate 41 on the frame 40, and setting a connecting section 32 on the support base 30, the connecting section 32 of the support base 30 is installed on the keyboard body 10 along the front-back direction, and the first reinforcing plate 41 is installed on the keyboard body 10 along the left-right direction. The support base 30 is limited, so that the connecting section 32 of the support base 30 and the first reinforcing plate 41 on the frame 40 respectively strengthen the rigidity of the keyboard body 10 from different directions, thereby improving the deformation resistance of the keyboard body and increasing the service life of the electronic keyboard.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
