Description

computer handheld remote control trackball

The utility model relates to a computer handheld remote control trackball.

Now, it is quite common for computer monitors to use a mouse to control the cursor on it or switch screens. But this mouse must be used normally on the flat terminal table in the computer room, and it also has cables to be connected with the computer host. For portable or notebook computers, when often needing to be carried outside the machine room and placed on the lap for operation, this mouse is just difficult to adapt to the situation without a flat desktop. For this reason, people particularly hope that a kind of novel " mouse " that can hold in hand and control and can wireless remote control work come out. Recently, the Taiwan area has adopted the computer mouse of infrared ray emission remote control to develop successfully and put into production and market sale. Its remote control receiving effect is still good, but the external appearance of this remote control computer mouse is still a traditionally used mouse structure, which is not suitable for holding and operating in the hand, and it is very inconvenient to use.

The purpose of the utility model is to provide a computer hand-held remote control trackball which can be held by the user and conforms to the ergonomic design and is convenient to operate and use.

The utility model is realized in the following way: it mainly includes an organic body, a ball seat, a track ball and a button, and is characterized in that: a grip part is arranged on the body, and two sides of the grip part are provided with matching finger pulp curvature and palm curvature. Edge, the body is provided with an operation part at an appropriate position from the grip part, the front end of the operation part is connected with a cover body, and an arc-shaped ball seat is provided at an appropriate position on the front of the operation part, and the ball seat A trackball is embedded in the middle, and the operation part is provided with a curved stop body on both sides at an appropriate position on the back. As for the button used for dragging the button, the body is provided with a button used as a confirmation button at an appropriate place between the ball seat and the grip part to cooperate with the movement curvature of the thumb.

The above-mentioned key used as the confirmation key is a key body spanning the body, and the two ends of the key body are curved upwards. Easily press against the key that serves as the OK key.

The above-mentioned ball seat is provided with a cover body that can just protrude from the track ball, and the ball seat is provided with a surface edge along the surface curvature of the cover body on the periphery of the joint between the ball seat and the cover body. The key tops used by the OK key are on the same plane. So that after the thumb moves the trackball, the thumb can smoothly slide down on the key from the surface of the cover body through the edge of the ball seat.

The grip part of the above-mentioned body is provided with a groove adjacent to the blocking body at an appropriate position on the back side, and the two sides of the groove are respectively provided with wall surfaces extending upward according to the curvature of the finger pulp, so that the hand held on the body When the thumb and forefinger on the palm move at the same time, the palm can hold the middle finger in the groove, and the body is not easy to slip out of the user's palm through the barriers on both sides of the groove.

The utility model relates to a trackball device for a hand-held remote control computer. The body of the device is provided with a grip part for users to hold and conforms to ergonomic design. There is an operating part conforming to the size of the human body, and the operating part is provided with a part of the palm to hold the body, and the computer can be manipulated through the trackball and the determination key that the thumb can reach in the holding part. There is a stop body under the appropriate position of the operation part, and the stop body is provided with a drag key that can let the index finger rest on it, so that the index finger under the body can naturally bend inwards and rest on the drag key of the block body, and at the same time use The thumb moves the trackball in the ball seat, and the signal is sent out through the transmitter, and the indication or picture on the display is remotely controlled or switched. The device is provided with a groove just adjacent to the stop body for the middle finger to press against. When the user uses the finger and forefinger to move the trackball and press the button on the stop body respectively, the two sides of the groove can go upwards. The extended wall blocks against the two sides of the middle finger protruding into the groove, so that the body is not easy to come out from the palm. Among them, the button used as the OK button is a button body that spans the body. The two ends of the button body are curved upwards, so that the user can easily press the thumb against the button regardless of whether the user holds it with the left or right hand. on the button body. A ball seat for embedding the trackball is arranged on the operation part, and a cover body matching the protruding curvature of the trackball is buckled on the ball seat. The edge of the arc is so that when the thumb moves precisely, the trackball can be moved smoothly without the drop between the cover and the trackball, and the surface of the cover can pass through the edge of the seat. Slide smoothly onto the OK key.

Fig. 1 is a perspective view of the utility model.

Fig. 2 is the schematic diagram when the utility model is implemented.

Referring to Fig. 1, the utility model mainly comprises components such as organic body 1, ball seat 2, trackball 3, button 4 and cover body 5. Wherein, a gripping portion 11 is provided on the body 1, edges 12 matching the curvature of the finger pulp and the curvature of the palm are respectively provided on both sides of the gripping portion 11, and the body 1 is provided with a The operation part 13, the front of the operation part 13 is equipped with a ball seat 2 matching the surface curvature of the grip part 11, a track ball 3 is placed in the center of the ball seat 2, and a cover 21 is embedded and buckled on the ball seat 2, The cover body 21 is provided with a slot 22 for the trackball 3 to protrude, and the operation part 13 is embedded with a button 4 used as a confirmation key to match the movement curvature of the thumb between the ball seat 2 and the grip part 11 . Furthermore, the body 1 is provided with a transparent cover body 5 at the front end of the operation part 13, and the circuit board in the body 1 is provided in the cover body 5 (because the design of the circuit board is the same as that of a general remote controller, and it is not the same as this circuit board). The intended scope of protection of the utility model, so do not go into details here and mark in the drawing) the transmitting part 51 that connects. The body 1 is provided with a downwardly extending baffle 14 at an appropriate position on the back side of the operation part 13, and both sides are curved. Button 4.

The grip part 11 of the machine body 1 in the present utility model is provided with a groove 15 adjacent to the retaining body 14 at an appropriate position on the back, and the two sides of the groove 15 are respectively provided with wall surfaces extending upwards in accordance with the curvature of the finger pulp. 16. When the thumb and forefinger held on the palm of the body 1 move at the same time, the palm can embed the middle finger in the groove 15, and the body 1 is not easy to use due to the blocking of the wall surfaces 16 on both sides of the groove 15. slipped out of the palm of the victim.
