Problems solved by technology

[0003] At present, the installation method of the unitary infrared positioning module is often glued to the screen protection glass of the interactive device. This is mainly to adapt to the small size of the unitary infrared positioning module and further reduce the size of the whole machine; The glue on the protective glass is not easy to remove or clean, and it is not easy to carry out follow-up maintenance

Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, it is a structural schematic diagram of a fixing device for an infrared positioning unit in the present invention. It includes a spliced ​​surface frame 1, a semi-closed cavity is formed inside the spliced ​​surface frame 1, an infrared positioning unit 4 is arranged in the semi-closed cavity, and an infrared positioning unit is installed in the semi-closed cavity. The position-limiting mechanism, the position-limiting mechanism is a pressure frame plate 2, one side of the pressure frame plate 2 is installed on the inner side of the spliced ​​face frame 1, and the other side of the pressure frame plate 2 is used to compress the limit infrared positioning unit 4.

[0032] The splicing of the spliced ​​face frame 1 can be spliced ​​according to the needs of those skilled in the art, and it only...

Abstract

The invention relates to the technical field of touch screens, in particular to a fixing device for an infrared positioning unit. The fixing device comprises a splicing surface frame, wherein a semiclosed cavity is formed on the inner side of the splicing surface frame; an infrared positioning unit is arranged in the semiclosed cavity; and a limiting mechanism for pressing and limiting the infrared positioning unit is arranged in the semiclosed cavity. The characteristic of small size of the conventional infrared positioning unit is fully used; under the conditions that the function and the performance of the infrared positioning unit are not influenced and the size of the whole device is reduced to the minimum, the fixing device can be used for assembling and fixing the infrared positioning unit in an extremely small space smartly; the fixing device has the advantages that the occupied space is small, the assembly mode is simple and reliable, the positioning precision is high, and extra position adjustment is not needed; the splicing surface frame is fully used as a part of the fixing device; and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a fixing device for an infrared positioning unit. Background technique [0002] At present, the application of infrared positioning technology in the field of digital interactive products has become more and more extensive and mature, and is developing in the direction of multi-touch, modularization, and miniaturization, and is widely used in digital display, teaching, conferences, demonstrations, etc. . At present, the infrared positioning module is mainly divided into two implementation methods: one is directly set on the digital interactive device, and forms a complete infrared positioning system together with the frame of the digital interactive device; the other is designed as an independent module, which is called here It is an infrared positioning unit, and the infrared positioning unit is assembled on the digital interactive device after debugging. This method has ...
