Problems solved by technology

[0007] The purpose of the present invention is to solve the problems that existing displacement speed sensors must rely on stationary parts, have poor complete sets, and are not widely used, and provide people with a displacement sensor that can be completed independently, does not need to rely on stationary parts, and has a wide range of applications. speed sensor
[0008] Another object of the present invention is to solve the problem that the existing mouse must rely on a stationary desktop or mouse pad, which is inconvenient to operate and easily causes "mouse hands", and provides people with a mouse that does not rely on stationary parts and can leave the mouse. Desktop operation, convenient and effective, avoiding "mouse hand", and an off-desk mouse that can indirectly exercise the wrist

Embodiment 1

[0045] Embodiment 1: Displacement velocity sensor, comprises optical signal transmitter 12, optical signal receiver 13 and displacement velocity sensor, and displacement velocity sensor comprises arc surface shell 1, the inertia positioning ball 2 in arc surface shell 1. In this embodiment, the optical signal transmitter 12 is an infrared emitting tube, and the optical signal receiver 13 is an infrared receiving tube. Inertial positioning ball 2 is a eccentric ball, and the center of gravity is located on the central axis below its center of sphere. The curved shell 1 is spherical. As shown in Fig. 1 and Fig. 2, the displacement speed sensor also includes around the inertial positioning ball 2, two roller grating wheels 7 and a pinch wheel 8 at right angles to each other, which are fixed on the inner spherical surface of the arc surface shell 1, and the pinch wheel 8 The angle between the two roller grid wheels 7 is in the opposite direction, and they are on the same plane, s...

Embodiment 2

[0048] Embodiment 2: As shown in Figure 3, the off-desk mouse is improved on the basis of the existing semi-optical mechanical mouse. The structures of the two soft-touch buttons 4 and the scroll wheel 5 between the two are the same as those of the existing semi-opto-mechanical mouse. The difference is that the rolling ball originally placed in the cavity at the bottom of the mouse plane is changed to an inertial positioning ball 2, and the plane bottom of the original mouse extends downwards and is fixedly connected with the arc surface shell 1 (the arc surface shell 1 in this example is spherical) . The inertia positioning ball 2 in this embodiment is also an eccentric ball, and its spherical surface and the inner spherical surface of the curved shell 1 are smooth surfaces. The center of gravity of the inertia positioning ball 2 is located on the central axis below its center of sphere. Around the inner spherical surface of the arc surface shell 1 and the inertia positioni...

Embodiment 3

[0051] Embodiment 3: As shown in Figure 4, the off-desk mouse is improved from the photoelectric mouse. Optical signal transmitter 12, optical signal receiver 13, microprocessor, light touch button 4, scroll wheel 5 etc. are all arranged in the common photoelectric mouse of top. Its displacement speed sensor is made of arc surface shell 1 (spherical), inertia positioning ball 2. The inertia positioning ball 2 is provided with a gyroscope inside, and the inertia positioning ball 2 "automatically" returns to the initial state after rolling by relying on its self-stabilizing balance, so as to realize the relative displacement and speed with the arc surface shell 1. An opening is arranged at the upper end of the arc surface shell 1, and the inertia positioning ball 2 is built in the arc surface shell 1, and the arc surface shell 1 is fixedly connected with the shell of an ordinary photoelectric mouse. The inner spherical surface of the arc surface shell 1 and the spherical surfac...

Abstract

A displacement speed transducer consists of displacement speed sensor formed by arc form shell and inertia positioning ball set in shell. It is featured as applying smooth surface as contact surface of arc form shell and inertia positioning ball for decreasing frictional force of said ball. The desk - off type of mouse applying displacement speed sensor can be operated without desk surface or the other static plane and it can be operated remotely in suspension way.

Description

technical field [0001] The present invention relates to a displacement speed sensor used in the fields of industrial control and home appliance control, and a computer-operated control mouse using the sensor, in particular to a displacement speed sensor and a distance sensor that moves on a spherical surface and does not require an external static reference object. Desktop mouse. Background technique [0002] At present, in industrial control, home appliance control, and computer operation control, the displacement speed sensor is used to sense the displacement and speed of the object under test or the control part in the operation control, and then the signal of this displacement and speed changes in the optical signal transmitter , The displacement and speed of the grid movement between the optical signal receivers, so that the optical signal receivers receive intermittent optical signals, and these intermittent optical signals are converted into electrical signals, which ...
