As shown in fig. 1, the first and second

key regions

11 and 21 are each provided with a space bar 41.

Generally, only one space key 41 is needed to be arranged on one keyboard, so that in this embodiment, after the keys 40 are respectively arranged on the first keypad 11 and the second keypad 21, only the space key 41 needs to be arranged on the first keypad 11 or the second keypad 21, but since some users prefer to operate the space key 41 with the left hand and some users prefer to operate the space key 41 with the right hand, the space keys 41 are arranged on both the first keypad 11 and the second keypad 21, thereby meeting the requirements of various user groups.

A second embodiment of the present invention is shown in fig. 4, which is substantially identical to the first embodiment of the present invention, except that the ergonomic keyboard further comprises a space bar spanning between the first keypad 11 and the second keypad 21, and in particular, the space bar of this embodiment is a bent space bar 42.

Since the bending type space key 42 is already located across the first and second

key regions

11 and 21, the user can operate the bending type space key 42 on the first key region 11 with the left hand and operate the bending type space key 42 on the second key region 21 with the right hand, i.e., the same function is achieved in a different manner from the first embodiment.

A third embodiment of the present invention is shown in fig. 5 to 8, which is substantially identical to the first embodiment of the present invention, except that the ergonomic keyboard further includes a third base plate 30, the first base plate 10, the second base plate 20 and the third base plate 30 are sequentially connected to each other, a third key zone 31 is formed on a top surface of the third base plate 30, and a plurality of keys 40 are also formed on the third key zone 31; in the direction of looking down on the ergonomic keyboard, the included angle between the second key region 21 and the third key region 31 is an acute angle c, so that the second key region 21 and the third key region 31 are arranged away from the user side and close to the user side.

For example, in the first embodiment of the present invention, the first keypad 11 and the second keypad 21 are not used for setting numeric keypads, and after the third keypad 31 is added, the numeric keypads can be set by using the third keypad 31, thereby meeting the use requirements of different users.

In addition, when the user uses the right hand to transfer from the second keypad 21 to the third keypad 31, the right hand does not move translationally, but habitually uses the right elbow as the rotation center to control the forearm to rotate clockwise, so that after the second keypad 21 and the third keypad 31 are arranged in the form of the included angle shown in fig. 7, the user only needs to naturally rotate the right forearm to realize the smooth transition of the hand from the second keypad 21 to the third keypad 31, thereby providing a smoother and smoother use experience for the user.

As shown in fig. 7, an included angle (acute angle c) between the second key region 21 and the third key region 31 is 15 ° to 30 ° in a direction of looking down on the ergonomic keyboard.

The angle parameter setting is selected according to the swing range of the hand of most users, so that the hand can be more comfortably and smoothly transferred from the second key area 21 to the third key area 31 after the parameter setting is adopted.

As shown in fig. 8, an included angle between the third bottom plate 30 and the second bottom plate 20 is an obtuse angle d, and the third bottom plate 30 is used for flatly placing on the placing position of the ergonomic keyboard.

The arrangement mode has the advantages that the smooth arrangement of the third bottom plate 30 can increase the contact area between the ergonomic keyboard and the arrangement position, so that the ergonomic keyboard can be stably arranged and fixed; and when the hand is transferred from the second key region 21 to the third key region 31, the hand is already in an extended state, and the third bottom plate 30 is arranged to be flatly placed, so that the appearance of the extended state of the hand is matched with that of the third bottom plate, and the user can still keep extremely high comfort in the whole operation process.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
