Description
Technical Field
[0001] The utility model relates to the technical field related to guitars, in particular to a guitar shell designed in accordance with ergonomics. Background Art
[0002] At present, commonly used guitars generally include a neck bottom shell, on which a neck cover is bonded to form a complete neck shell, and the outer bottom surface of the neck bottom shell is generally symmetrically arranged in an arc shape. The upper half of the guitar neck connected to the headstock is the low position, and the lower half connected to the guitar body is the high position. When a user uses a guitar, the general standard playing hand shape is that the thumb will be held on the arc surface of the bottom surface of the neck. When holding it in the low position, the left thumb is held on the right side of the bottom surface of the low position (the upper side when the neck is placed horizontally on the left), and the transition arc between the thumb and the index finger is just placed on the low position of the bottom surface of the neck. The left side of the neck (the lower side when the neck is placed horizontally on the left side), and the bottom surface of the traditional guitar neck is generally symmetrical, so the arc of the bottom surface of the low neck position is not very compatible with the arc between the user's thumb and index finger, which will reduce the user's experience when using it; as the playing progresses, when the playing moves from the low position to the high position, the position of the left thumb also moves from the right side of the bottom surface of the low neck position to the left side of the bottom surface of the high position, and the symmetrical arc design of the traditional guitar neck at the high position is also not compatible with the arc when the thumb holds the neck, which will also reduce the user's experience when using it. When users pick up the guitar, they generally use their right hand to hold the high position to pick it up. The traditional symmetrical arc design is not compatible with the arc between the thumb and index finger of the right hand, which reduces the user's experience when picking it up. Utility Model Content
[0003] The purpose of the utility model is to provide a guitar shell with an ergonomic design, aiming to solve the above technical problems. The utility model mainly designs an asymmetrical curvature of the bottom surface of the neck according to the movement trajectory of the thumb of the user on the bottom surface of the neck when using the guitar instrument, so that the setting of the utility model is more ergonomically designed and effectively improves the user's usage experience.
[0004] In order to achieve the above object, the utility model is implemented through the following technical solutions:
[0005] A guitar shell accordant with ergonomic design comprises a neck shell, wherein the radial section where the neck shell connects with the headstock is set as an upper neck section, the radial section in the middle of the neck shell is set as a middle neck section, the radial section where the neck shell connects with the guitar body is set as a lower neck section, the portion from the upper neck section to the middle neck section is set as a low position, and the portion from the middle neck section to the lower neck section is set as a high position, and the bottom surfaces of the low position and the high position are both asymmetrically designed.
[0006] Preferably, the arc shape of the bottom surface of the low grip is adapted to the arc between the thumb and index finger of the left hand of a human body.
[0007] Preferably, based on the vertical center line from the head to the body of the guitar on the guitar neck shell, the arc length of the left arc of the cross section of the guitar neck is greater than the arc length of its corresponding right arc, and the radius of the left arc is greater than the radius of the right arc.
[0008] Preferably, the arc shape of the bottom surface of the high grip position is adapted to the arc between the thumb and index finger of the right hand of the human body.
[0009] Preferably, the neck shell is based on the vertical center line from the head to the body, the arc length of the left arc of the lower cross section of the neck is smaller than the arc length of its corresponding right arc, and the radius of the left arc is smaller than the radius of the right arc.
[0010] Preferably, the arc length of the left arc of the middle cross section of the neck is equal to the arc length of its corresponding right arc, and the radius of the left arc is equal to the radius of the right arc.
[0011] Preferably, the instrument further comprises a body shell, the upper end of the body shell is connected to the lower end of the neck shell, and the outer edge of the body shell is rounded.
[0012] Preferably, the instrument further comprises a head shell, the lower end of the head shell being connected to the upper end of the neck shell.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0022] like Figure 1 As shown, a guitar shell accordant with ergonomic design includes a head shell 1, a neck shell 2 and a body shell 3, wherein the lower end of the head shell 1 is connected to the upper end of the neck shell 2, and the upper end of the body shell 3 is connected to the lower end of the neck shell 2.
[0023] like Figure 2 and Figure 3As shown, the radial section where the neck shell 2 connects with the headstock is set as the upper neck section 201, the radial section in the middle of the neck shell 2 is set as the middle neck section 202, the radial section where the neck shell 2 connects with the body of the instrument is set as the lower neck section 203, the part from the upper neck section 201 to the middle neck section 202 is set as the low position 204, the part from the middle neck section 202 to the lower neck section 203 is set as the high position 205, and the bottom surfaces of the low position 204 and the high position 205 are both asymmetrically designed.
[0024] like Figure 2 and Figure 3 As shown, the arc of the bottom surface of the low position 204 is adapted to the arc between the thumb and index finger of the left hand of the human body; the vertical center line from the head to the body of the guitar on the neck shell 2 is used as a reference, and the arc length of the left arc of the upper cross-section 201 of the neck is greater than the arc length of its corresponding right arc, and the radius of the left arc is greater than the radius of the right arc.
[0025] like Figure 2 and Figure 3 As shown, the arc of the bottom surface of the high position 205 is compatible with the arc between the thumb and index finger of the right hand of the human body; the neck shell 2 takes the vertical center line from the head to the body of the guitar as a reference, and the arc length of the left arc of the lower cross-section 203 of the neck is smaller than the arc length of its corresponding right arc, and the radius of the left arc is smaller than the radius of the right arc.
[0026] like Figure 1 and Figure 3 As shown, the arc length of the left arc of the middle section 202 of the neck is equal to the arc length of its corresponding right arc, and the radius of the left arc is equal to the radius of the right arc; the outer edge of the body shell 3 is rounded.
[0027] It should be noted that: in the present embodiment, the shape of the upper cross-section 201 of the neck to the middle cross-section 202 of the neck gradually transitions from an asymmetrical shape with the left side longer and the right side shorter to a symmetrical shape with equal lengths on both sides, and then from the middle cross-section 202 of the neck to the lower cross-section 203 of the neck, it gradually transitions from a symmetrical shape with equal lengths on both sides to an asymmetrical shape with the left side shorter and the right side longer. In this way, the lowest point connection line of the bottom surface shape of the neck shell 2 forms a lowest point trajectory line, and this lowest point trajectory line is a line connecting the right side of the low position 204 to the middle of the middle part, and then transitions to the left side of the high position 205. The direction of this lowest point trajectory line just meets the moving trajectory line of the contact position between the left thumb of the user and the bottom surface of the neck shell 2 when the user is playing. This makes the design of the present invention more in line with the design of ergonomics, so that the present invention can effectively increase the user's experience when playing.
[0028] When a user normally uses a guitar, the guitar is generally placed horizontally with the groove below placed on the leg, and the right-angled corners of the guitar body side panels and the guitar body panel of the upper groove just touch the user's ribs. When the user's body applies a certain amount of pressure to the guitar, the sharp guitar corners will cause a certain amount of discomfort to the user's ribs. In this embodiment, the guitar head bottom shell, the neck bottom shell and the guitar body bottom shell are integrally injection molded, and the guitar head cover, the neck cover and the guitar body cover are also integrally injection molded. The guitar body shell 3 is composed of the guitar body. The bottom shell and the body cover are buckled together, which reduces the side panel components of the guitar body, thereby reducing the connection angle between the side panel and the bottom panel of the guitar body, and reducing the connection angle between the side panel and the top panel of the guitar body. In this embodiment, the corners of the bottom shell and the body cover are rounded to reduce the protruding sharp angles. When the bottom shell and the body cover are buckled together to form a complete guitar body shell 3, the side edges thereof are all arc-shaped transitions, which not only reduces the discomfort to the user during use and increases the experience, but also greatly improves the overall aesthetics of the guitar shell.
