Description

Magnetic damping extremely-fast optical wheel and mouse

Technical Field

A mouse is a computer input device for controlling movement and clicking operations of a cursor on a computer screen. The cursor position in the computer is controlled by the movement of the hand. The mouse is widely applied to personal computers, notebook computers and other computer equipment, and is one of important tools in man-machine interaction.

A mouse typically has two or more buttons that can be operated by left, right, and scroll wheels. Among them, the optical mouse wheel is a wheel that detects a scrolling direction and speed using an optical sensor. It is smoother and more accurate in rolling than a mechanical roller. The optical scroll wheel is typically comprised of an LED that illuminates the scale on the scroll wheel and a photosensor that detects the rotation of the scroll wheel and converts it into a digital signal that can be understood by a computer. The optical roller has advantages in its durability and durability. It has no mechanical parts compared to mechanical rollers and is therefore less prone to wear or damage. In addition, the optical roller can provide higher resolution and precision, so that the rolling is smoother and more accurate. Mice employing optical scroll wheels are therefore becoming increasingly popular with consumers.

However, most of the optical rollers on the market today are to fixedly arrange the optical transmitting terminal and the optical receiving terminal on the fixing support of the optical roller to monitor the rotation state of the roller, and this structural arrangement further aggravates the quality on the support, and affects the control flexibility. In addition, the optical transmitting terminal and the optical receiving terminal of the structure need to be provided with soft connecting wires for electric connection with the main board. However, the connecting wire is easily broken due to fatigue under long-time high-frequency clicking, and the service life of the mouse is further affected.

Therefore, the above-mentioned existing technical drawbacks need to be changed.

In one aspect, the utility model provides a magnetically damped, extremely fast optical wheel as shown in fig. 1, 2, 3 and 4, which can be mounted on a mouse and is an important component of the mouse, and the rolling and switching of computer screen pages are controlled by rotation. The main structure comprises: the mouse comprises a PCBA board 1 and a bracket assembly 2, wherein a middle key 11 is arranged on the PCBA board 1, the bracket assembly 2 comprises a fixed base 21 and a bracket 22, the fixed base 21 is fixedly connected to the mouse shell or the PCBA board 1, one end of the bracket 22 is movably connected to the fixed base 21, and the other end of the bracket 22 is abutted to the middle key 11;

The support 22 is rotatably connected with a roller 02, a plurality of light-transmitting holes 2232 are uniformly distributed on the roller 02 around the axis of the roller 02, and two ends of the pcba board 1 corresponding to the light-transmitting holes 2232 are respectively provided with an optical transmitting terminal 12 and an optical receiving terminal 13.

It should be noted that, most of the optical rollers on the market today fixedly arrange the optical transmitting terminal 12 and the optical receiving terminal 13 on the fixing support 22 of the optical roller 02 to monitor the rotation state of the roller, and this structure arrangement further aggravates the quality on the support 22, and affects the operation flexibility thereof. In addition, the optical transmitting terminal 12 and the optical receiving terminal 13 of this structure need to be provided with flexible connection wires to be electrically connected to the motherboard. However, the connecting wire is easily broken due to fatigue under long-time high-frequency clicking, and the service life of the mouse is further affected.

The optical transmitting terminal 12 and the optical receiving terminal 13 of the scheme are respectively separated from the bracket 22, the optical transmitting terminal 12 and the optical receiving terminal 13 are directly fixed on the PCBA board 1, the bracket 22 is prevented from interfering with the transmission of light beams between the optical transmitting terminal 12 and the optical receiving terminal 13 through structural design, and the roller is not interfered with the optical transmitting terminal 12 and the optical receiving terminal 13 in the clicking and pressing process. The weight on the support 22 can be further reduced, and the flexibility of roller manipulation can be improved. Wherein, because the optical transmitting terminal 12 and the optical receiving terminal 13 are hard-connected with the PCBA board 1, the condition of wire breakage caused by active fatigue is avoided, and the service life of the mouse can be prolonged.

Further, as shown in fig. 2 and 3, the roller includes a magnetic inner shaft 222 and a magnetic outer shaft 223, the magnetic inner shaft 222 and the magnetic outer shaft 223 are disposed inside the bracket 22 through the metal shaft 221, the magnetic outer shaft 223 rotates around the outer circumference of the magnetic inner shaft 222, the surface of the magnetic inner shaft 222 is uniformly provided with first magnetic teeth 2221 in an array, the inside of the magnetic outer shaft 223 is provided with second magnetic teeth 2231 corresponding to the first magnetic teeth 2221, the light-passing holes 2232 are disposed between adjacent second magnetic teeth 2231, and the light-passing holes 2232 penetrate through the magnetic outer shaft 223.

Further, as shown in fig. 3 and 4, the bracket 22 is provided with a dodging channel 224 at a position corresponding to the beam paths of the optical transmitting terminal 12 and the optical receiving terminal 13. In addition, when the user presses the roller, the bracket 22 will displace downward along with the roller, so the avoidance channel 224 needs to extend along the moving direction of the bracket 22, so as to avoid the bracket 22 from blocking the light beam transmission; the avoidance channel 224 is configured to allow the light beam emitted from the optical emission terminal 12 to pass through the light-passing hole 2232 smoothly, and then reach the other end of the support 22 to irradiate the optical receiving terminal 13. The relief channel 224 is seen to be provided to prevent the bracket 22 from blocking normal transmission of the beam.

Further, as shown in fig. 3, a shaft sleeve 2233 is disposed on the surface of the magnetic outer shaft 223, a leather ring 2235 is sleeved on the surface of the shaft sleeve 2233, and anti-slip lines are disposed on the outer surface of the leather ring 2235. It will be appreciated that the anti-slip texture may increase the friction between the user's finger and the apron 2235, preventing slippage.
