Abstract

A table tennis table for competition belongs to the technical field of sports equipment, and is characterized by comprising a left table device, a right table device, a left sensor, a right sensor, 4 groups of displays, a left control box, a right control box, two groups of skirt boards and a plurality of groups of wires. The left sensor and the right sensor are respectively adhered to the front edge, the rear edge and the middle edge of the left table board and the right table board, when a table tennis ball impacts the upper brim edges of the left sensor and the right sensor on the left table board and the right table board, a 'touch' signal generated by the sensors is amplified through the control box and is connected with the two groups of displays, so that the displays are turned off after being lighted for 1-3 seconds, and the situation that the table tennis ball touches the edges of the table boards is monitored for judgment by a judge. The method has the advantages of effectively avoiding disputes caused by subjective judgment of referees and improving the fairness of table tennis competition.

Description

Table tennis table for match

The technical field is as follows:

the utility model belongs to the technical field of sports equipment, concretely relates to table tennis table case of match usefulness.

Background art:

in table tennis, edge-wiping balls are often not fresh, and can become a turning point of a game at a key moment. In the real match, the table tennis flying at high speed brings great challenge to judge the edge ball for the judge, and the judgment is inaccurate due to the subjective judgment of the judge, so that the two parties in the match are not fast. Therefore, it is necessary to develop a new table tennis table capable of automatically monitoring edge ball.

The invention content is as follows:

the utility model aims at providing a table tennis table case of match usefulness can effectively avoid the dispute that the subjective judgement of judge arouses to improve the fairness of table tennis judge result.

The utility model is realized as the following, as shown in figure 1, the utility model is characterized in that the table comprises a left table device A, B and a right table device A, B which have the same structure and are symmetrical left and right, wherein the left table device A is illustrated as an example: the left stage device a includes: left table A1, left sensor A2 in the shape of "ㄈ", left front and rear displays A3, A3^’A left control box A4, a left front, a left back and a left middle apron board A5 and A5^’A5 ″, left front, left rear, left middle conductor group A6, A6^’A6 "; the assembly relation is as follows: left front, left back and left middle skirting boards A5 and A5^’A5' are respectively arranged below the front edge, the rear edge and the middle edge of the left table-board A1; the left sensor a2 in the shape of "ㄈ" is glued over the front, back and middle edges of the left deck a 1; left front and rear displays A3, A3^’The front middle position and the rear middle position are respectively arranged below the left table top A1; the left control box A4 is arranged at the middle position below the left table-board A1; the left control box A4 passes through the left front, back and middle conductor families A6 and A6 respectively^’A6' and left front display A3 and left rear display A3^’And a left sensor A2 in the shape of "ㄈ"; as shown in fig. 2 and 3, the length of the side edge of the left sensor a2 in the shape of "ㄈ" is 10mm-75mm less than that of the side edge of the left table top a 1.

Compared with the prior art, the utility model following advantage has:

1. the application of the new technology can avoid disputes caused by judging the edge ball subjectively by the judge, and improve the fairness of the table tennis competition.

2. Different from the eagle eye based on visual sensing, the eagle eye also needs to be judged subjectively; the method is an automatic touch sensing display detection technology, does not need human judgment, and increases a technical scheme for judging the edge ball in the match to be more objective and effective.

3. Simple structure and easy realization.

Description of the drawings:

FIG. 1 is a schematic three-dimensional general assembly of a table tennis table for use in a game;

FIG. 2 is an enlarged view of a portion of C of FIG. 1;

fig. 3 is a schematic view of the shapes of the left sensor a2 and the right sensor B2.

In the figure: a-left desk table device, A1-left desk table, A2- "ㄈ" -shaped left sensor, A3, A3^’Left front and left rear displays, A4 left control Box, A5, A5^’A5' -left front, left rear, left middle apron board, A6, A6^’A6' -left front, left back and left middle conductor group, B-right desk table device, B1-right desk table, B2- ㄈ -shaped right sensor, B3, B3^’Right front and rear displays, B4-right control boxes, B5, B5^’B5' -right front, right back and right middle apron board, B6, B6^’B6 "-right front, right rear, right center conductor family.

The specific implementation mode is as follows:

as shown in figure 1, when a table tennis ball hits the edge of the upper brim of the left sensor A2 in the shape of 'ㄈ' on the left table A1 in the table tennis table for competition, the 'touch' signal generated by the left sensor A2 in the shape of 'ㄈ' on the left table A1 is amplified by the left control box A4 and is switched on the left front and left rear displays A3 and A3^’The left front and the left back displays A3 and A3^’Turning off after lighting for 1-3 seconds, and indicating that the table tennis ball touches the edge of the left table device A; when the table tennis ball hits the edge of the upper eave of the right sensor B2 in the shape of 'ㄈ' on the right table top B1, the 'tactile' signal generated by the right sensor B2 in the shape of 'ㄈ' on the right table top B1 is amplified by the right control box B4 and is switched on the right front display B3 and the right rear display B3^’The right front and rear displays B3 and B3^’And (4) turning off after lighting for 1-3 seconds, and indicating that the table tennis ball touches the edge of the left table case device B, thereby providing a basis for judging whether the table tennis ball touches the edges of the upper eaves of the two table cases for a judge.
