Description

Computer mouse

Technical Field

The present invention relates to a computer mouse, and more particularly, to increase the precision of the operation of the switch to perform a variety of functions and to enhance the user's convenience with the ergonomic design and the structure to be easy to operate by the user Relates to an improved computer mouse.

Background

In general, a computer mouse includes a first case in which a touch member that can be touched by a user is protruded to the outside, and a second that is coupled to the first case to close an electric component disposed inside the first case. It consists of a case. Such a computer mouse is connected to a computer and functions to produce a desired result according to a software design specification. However, the computer mouse according to the related art as described above has the following problems.

That is, the conventional computer mouse is designed to be symmetrical with respect to the center line passing through the touch member as shown in FIGS. 1 and 2. Therefore, when the user intends to grip and manipulate the computer mouse by hand, the wrist is bent at a certain angle A1 as shown in FIG. 1 as the computer mouse is disposed closer to the user. In this case, there is a problem of fatigue and discomfort to the user as the force to release the bending to the wrist portion of the user is continuously applied. In particular, in the case of a gaming mouse, a switch for performing various functions is provided on the lower surface of the computer mouse, and needs to be used in close proximity to the user. In this case, the above problems are more prominent.

In addition, the conventional computer mouse has a relatively convex shape in which the ratio of the left and right widths and the top and bottom widths of the user's palms is about 1.8: 1, so that the user tries to grip the computer mouse with the thumb and the finger ( In the case where the little finger touches the floor, as shown in FIG. 2, the back of the hand is bent at an angle A2 with respect to the arm, resulting in inconvenience to the user.

On the other hand, in addition to these problems, the conventional computer mouse has the following problems.

Third, the lower surface of the second case is formed flat to contact the bottom surface, the switch is coupled. The switch is generally used as a push switch, and serves to perform a specific function desired by the user by transmitting a signal to the electrical component disposed inside the first case by a user's operation. According to this structure, when the user grips the computer mouse and operates the switch, since the lower surface of the second case is formed flat, the switch is pressed even when the switch operation is not necessary, so that the user does not want to operate the switch. The result is printed on the monitor. In this case, due to the inaccuracy of the switch operation, it causes inconvenience or discomfort to the user, thereby lowering the reliability of the product.

Second, the first case is formed in an oval dome shape so that the user's palm can be placed. Therefore, when the user grips the first case and operates the switch, the thumb and the ring finger do not firmly grip the first case, and a slip phenomenon occurs between the finger and the first case. In this case, the precision of the switch operation is deteriorated, and if the force of gripping the first case is increased to prevent this, the user may feel a great fatigue and eventually reduce the product reliability.

In particular, such a problem is remarkable in gaming mice among computer mice. In view of the trend that the gaming industry is being activated in recent years, it is possible to increase the precision of product operation and to improve user convenience. There is an urgent need.

In addition, the computer mouse according to the prior art is formed flat so that the bottom surface of the second case is in contact with the bottom surface is coupled to the switch. The switch is generally used as a push switch, and serves to perform a specific function desired by the user by transmitting a signal to the circuit component disposed inside the first case by the operation by the user. According to this structure, when the user grips the computer mouse and operates the switch, the lower surface of the second case (C) is formed flat and the switch is on the same surface as the lower surface of the second case is in contact with the switch. Since is in contact with the switch, the switch is pressed even if the switch operation is not necessary, and the result that the user does not want is output on the monitor. In this case, due to the inaccuracy of the switch operation, it causes inconvenience or discomfort to the user, thereby lowering the reliability of the product.
