CN213934828U - Photoelectric mouse with front-mounted photosites and independently designed left and right keys - Google Patents

Abstract

The utility model discloses a photoelectric mouse with a preposed photosite and a left-right key designed independently. Including upper cover, base, general gyro wheel structure, PCB electronic circuit board, power, receiver, its characterized in that: a. the back is raised to have a curved surface and an inclined curved surface, so that the hand can be comfortable; b. the left and right keys are exposed out of the shell and are designed in the upper cover to touch the switch up and down; c. the use of a patch lens places the photosite in the front portion. Through the design, when the photoelectric mouse is operated, the wrist motion amplitude is obviously reduced, and meanwhile, the defect of front and back linkage of the traditional button during working is overcome by the independent small keys, so that the operation is more stable and flexible.

Description

Photoelectric mouse with front-mounted photosites and independently designed left and right keys

Technical Field

The design scheme of the utility model when involving mouse operation, the tiredness of wrist when specifically reducing the operation increases flexibility, stability, the punctuation rate of using the cursor.

Background

1. The prior photoelectric mouse arranges the photosites in the transverse middle area, when the mouse is operated, the wrist has large moving amplitude, and the wrist feels tired after long-time use;

2. the stability and moving feeling of the operation key are increased by using an iron block counterweight;

3. the smooth and wear-resistant pad is used, so that the optical standard point rate is poor, and the cursor is uncertain.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a design, the purpose is when solving and using the mouse, reduces tired sense, increases flexibility, stability and the punctuality rate that the cursor removed. In order to achieve the above object, the design of the present invention provides the following solutions:

1. the height of the raised back and the curved arc surface are just fit with the palm parts of the fingers, and the hands feel more comfortable when being placed on the palm parts;

2.30. the left and right inclined arc surfaces are suitable for the curvature of the fingers;

3. the independent left and right key positions are suitable for people with different finger lengths;

4. the thumb and the ring finger are provided with cambered surfaces at two sides for leaning;

5. the IC and the patch lamp special for the mouse are fixed on the PCB; the circle diameter part of the IC is matched with the patch lens to work;

6. the patch lens is arranged on the base, and the base is provided with a small photosensitive hole;

7. a rechargeable battery (or a battery is used as a power supply) is arranged, and a charging hole or a receiver is arranged;

8. the design purpose of independently touching the switch by the left key and the right key aims to overcome the defects that the traditional mode is used for linking the whole coordinate and two forces (switch elasticity and structural return force of the keys) need to be overcome; the upper and lower limited spaces provide simple and practical small-piece design, and the elasticity of the switch is only overcome, so that the comfort of the touch switch is improved;

9. the patch lens is used, compared with the traditional LED lamp lens, the space is greatly reduced, and conditions are provided for arranging the photosensitive point hole at the foremost part of the whole mouse; compared with the traditional mouse in which a large number of photosensitive holes are designed in the transverse middle area, the wrist movement range and fatigue are reduced; under the steady force movement of the thumb and the ring finger, the flexibility and the stability of the cursor are increased, so that the punctuality rate of a target point is improved.

Preferably, the upper cover, the lower cover, the left key and the right key in the design scheme are combined after being molded by ABS thermosetting plastic at one time, and the lens is molded by transparent PC engineering plastic.

The preferred left and right keys are designed as touch switches independently, and the return force of the keys is reduced.

The photosite of the optical mouse is preferably positioned at the foremost portion using a patch lens.

The utility model discloses a scheme, through the design of the curved cambered surface of back that rises, is fit for operating the rationality of controlling the button alone. Through the independent design of the left key and the right key, the appearance is more reasonable. By using the patch lens, the photosite of the optical mouse is arranged at the most front part, so that the return force of the key is reduced, the wrist movement amplitude during operation is reduced, the fatigue is reduced, the flexibility and the stability of the cursor are improved, and the aim point collimation rate is improved.

Detailed Description

The technical solution in the embodiment will be clearly and completely described below with reference to the drawings in the design and implementation examples of the present invention. Obviously, the embodiments described in the drawings are only a part of the embodiments of the present invention, and not all embodiments. Based on the embodiment case in the utility model, all other embodiment cases that ordinary skilled person in the art obtained under the prerequisite of not making creative work all belong to the utility model.

The design of independent left and right keys, the use of a patch lens and the arrangement of a photosite at the forefront are protected. Referring to fig. 1, 2 and 3, a new optical mouse is formed by molding and combining PC and ABS plastic monomers, and has a reasonable design and a practical and beautiful appearance. The scheme is that the mouse is formed by a raised back cambered surface, independent left and right keys, a patch lens and a front photosite, an electronic circuit board for controlling the mouse and a power supply and a receiver, wherein the mouse IC and the electronic circuit board are matched.

To sum up, the utility model relates to a scheme passes through the curved cambered surface of uplift back, controls the button alone, uses paster lens, leading photosite design, and the range of motion big problem of wrist when can solving the operation is easily touched and is controlled the button, reduces tiredly, increases flexibility, the stability purpose point punctuation rate of cursor.

Claims (1)

1. The utility model provides a photoelectric mouse that sensitization point is leading and control button independent design, includes upper cover, base, general gyro wheel structure, PCB electronic circuit board, power, receiver, its characterized in that: a. the back is provided with a raised cambered surface and a left and right 30-degree inclined cambered surface, so that the hand and the hand can feel comfortable; b. the left and right keys slightly exposed out of the shell are designed in the upper cover and touch the switch up and down; c. the use of the patch lens sets the photosite at the front end portion.
