[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1:

[0037] like Figures 1 to 11As shown, the present invention provides an ergonomic mechanical keyboard with adjustable functional areas, including a detachably connected main base plate 1 and a sub-base plate 2, the top surface of the main base plate 1 is provided with a main key area 11, and the top surface of the sub-base plate 2 is provided with a sub-key area 21, and a plurality of keys are provided on the main key area 11 and the sub-key area 21; the sub-base plate 2 is detachably connected to the left or right side of the main base plate 1 by a connecting member 3 to form a mechanical keyboard, that is, the main base plate 1 and the sub-base plate 2 are detachably connected by the connecting member 3, so that the user can install the sub-base plate 2 on the left or right side of the main base plate 1 according to the user's hand habit; here, the sub-key area 21 is the key in the numeric key area.

[0038] See also Figure 3 and Figure 6 As shown, when looking down at the mechanical keyboard, the width of the strip-shaped body 31 of the connector 3 gradually increases from the end closest to the user to the end farthest from the user, so that the angle between the main key area 11 and the sub-key area 21 is an acute angle a, and thus the main key area 11 and the sub-key area 21 are arranged far apart on the side farthest from the user, and close together on the side close to the user. In actual use, when the user's hand moves from the main key area 11 to the sub-key area 21, the palm does not simply move in a horizontal direction, but habitually controls the forearm to rotate clockwise or counterclockwise with the elbow as the center of rotation; therefore, the angle between the main key area 11 and the sub-key area 21 is an acute angle a, and the user only needs to naturally rotate his forearm to achieve a smooth transition from the main key area 11 to the sub-key area 21, which is ergonomic and provides the user with a smoother and smoother user experience.

[0039] See also Figure 1 and Figure 4 As shown, in the direction of looking down at the mechanical keyboard, the main base plate 1 is integrally connected to the palm rest main plate 4 near the user side, and the sub-base plate 2 is integrally connected to the palm rest sub-plate 5 near the user side. A palm rest main pad 41 is installed in the main pad groove opened on the upper surface of the palm rest main plate 4, and a palm rest sub-pad 51 is installed in the sub-pad groove opened on the upper surface of the sub-base plate 2. The palm rest main pad 41 and the palm rest sub-pad 51 are provided to provide support for the elbows when operating the keyboard to avoid soreness and discomfort caused by the elbows being suspended in the air for a long time.

[0040] See also Figure 3 、 Figure 6 as well as Figure 11As shown, the narrow end of the strip-shaped main body 31 is integrally connected to the block-shaped sub-body 32. The block-shaped sub-body 32 is an isosceles trapezoid. The two sides of the block-shaped sub-body 32 are designed with concave arcs, making the block-shaped sub-body 32 in the shape of an inverted funnel. In fact, in order to prevent the sharp edges and corners of the palm rest main board 4 and the palm rest sub-board 5 from scratching the user, the corners are chamfered to form a corresponding arc shape. Therefore, the two sides of the block-shaped sub-body 32 are designed with concave arcs to match the arc shape of the lower corners of the palm rest main board 4 and the palm rest sub-board 5, achieving a perfect fit. The left and right sides of the connector 3 have symmetrical card slots 33, which extend to the side of the strip-shaped main body 31 and the side of the block-shaped sub-body 32. The sub-bottom plate 2 and the main bottom plate 1 are detachably connected through the card slots 33 on the left and right sides of the connector 3. In fact, in order to ensure stability, the inner bottom surface of the card slot 33 and the side ends of the sub-bottom plate 2 and the main bottom plate 1 are embedded with magnets that attract each other, which can be stably connected and easily disassembled, thus achieving a detachable connection.

[0041] When the sub-base plate 2 is installed on the right / left side of the main base plate 1, the right / left end of the main base plate 1 and the palm rest main plate 4 are integrally snapped into the slot 33 on the left / right side of the connector 3, and the left / right end of the sub-base plate 2 and the palm rest sub-plate 5 are integrally snapped into the slot 33 on the right / left side of the connector 3; that is, the strip-shaped main body 31 connects the main base plate 1 and the palm rest main plate 4, and the block-shaped sub-body 32 matches and connects the sub-base plate 2 and the palm rest sub-plate 5, avoiding faults and ensuring smooth organization.

[0042] See also Figure 3 and Figure 6 When viewing the mechanical keyboard from above, the angle between the main keypad 11 and the secondary keypad 21 is between 15° and 30°. This angle is selected based on the hand swing range of most users, ensuring a smooth and comfortable hand movement from the main keypad 11 to the secondary keypad 21. When viewing the keyboard from the side, the angle between the main base plate 1 and the secondary base plate 2 is an obtuse angle (b), ensuring the secondary base plate 2 lies horizontally.

[0043] In this embodiment, the main base plate 1 and the secondary base plate 2 are detachably connected by a connector 3, allowing the user to install the secondary base plate 2 on the left or right side of the main base plate 1 according to their hand preference, meeting different user needs. Furthermore, the width of the strip-shaped body 31 of the connector 3 gradually increases from the end closest to the user to the end farther from the user, forming an acute angle a between the main keypad 11 and the secondary keypad 21. This results in the main keypad 11 and the secondary keypad 21 being arranged apart on the side farther from the user and closer together on the side closer to the user. When the user's hand moves from the main keypad 11 to the secondary keypad 21, the user only needs to naturally rotate their forearm to achieve a smooth transition from the main keypad 11 to the secondary keypad 21, which is ergonomic and provides the user with a smoother and more fluid user experience.

[0044] Example 2:

[0045] See also Figures 8 to 11 As shown, on the basis of retaining all the technical features in the specific embodiment one, the main base plate 1 is formed by integrally connecting a first base plate 12 and a second base plate 13. The top surface of the first base plate 12 is provided with a first key area 121, and the top surface of the second base plate 13 is provided with a second key area 131. The first key area 121 and the second key area 131 are both provided with multiple keys; in the side view direction of the mechanical keyboard toward the user, the first base plate 12 and the second base plate 13 are connected to form convex and concave, so that the angle between the first key area 121 and the second key area 131 is an obtuse angle c; in the direction of looking down at the mechanical keyboard, the angle between the first key area 121 and the second key area 131 is an acute angle d, so that the first key area 121 and the second key area 131 are arranged close to each other on the side away from the user, and arranged far away from each other on the side close to the user.

[0046] When the user places his hands on the table, the most natural position for the hands is with the palms facing downwards. Figure 2 、 Figure 5 as well as Figure 9 As shown, when the mechanical keyboard is viewed from the side of the user, the first base plate 12 and the second base plate 13 are connected in a convex shape, so that the angle between the first key area 11 and the second key area 21 is an obtuse angle c, so that the layout of the first key area 121 and the second key area 131 matches the natural orientation of the user's palms. Secondly, when the user places both hands at the same time, the two palms will naturally move closer together, and then the two elbows will move apart. Figure 8 As shown, in the direction of looking down at the mechanical keyboard, the angle between the first key area 121 and the second key area 131 is an acute angle d, so that the first key area 121 and the second key area 131 are arranged close to each other on the side away from the user, and arranged far apart on the side close to the user, so that the user can input with the palms close together; therefore, the above design is more in line with human ergonomics, and does not require the human palm to be extended outward at a certain angle relative to the arm, so that the user can save effort and feel more comfortable, solving the problem of discomfort in using existing keyboards.

[0047] See also Figure 1 、 Figure 2 as well as Figure 4 and Figure 5 As shown, the palm rest main plate 4 is tilted downward with the connection with the main bottom plate 1 as the highest point, and the palm rest sub-plate 5 is tilted downward with the connection with the sub-bottom plate 2 as the highest point; in fact, the palms of the user are in a tilted downward state, and the forearm is also in a tilted downward state in the direction from the palm to the forearm. At this time, the tilt settings of the palm rest main plate 4 and the palm rest sub-plate 5 match the tilt placement of the forearm, so that the user can get a comfortable experience for the hand.

[0048] More specifically, when looking sideways at the mechanical keyboard toward the user, the angle between the first key area 121 and the second key area 131 is 110° to 130°; when looking down at the mechanical keyboard, the angle between the first key area 121 and the second key area 131 is 15° to 30°; the above parameter settings are selected based on the hand swing amplitude of most users, which can achieve a better experience effect.

[0049] See also Figure 7 As shown, the first keypad 121 and the second keypad 131 are both provided with a space bar 61 and a B key 62. In fact, the first keypad 121 is provided with the keys to the left of F4, 5, T, G, and B on a standard keyboard, while the second keypad 131 is provided with the keys to the right of F5, 6, Y, H, and B. At the same time, the rightmost column of the second keypad 131 is adaptively supplemented with the INS, HOME, EDN, PGUP, and PGDN keys from top to bottom, while the DEL key is supplemented to the top of the sub-keypad 21. The space bar 61 and the B key 62 are provided on both the first keypad 121 and the second keypad 131. Users can more conveniently and adaptively choose to press the space bar 61 and the B key 62 with their left or right hand according to their fingering habits, providing a better user experience.

[0050] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
