Description

Technical Field

[0001] This utility model relates to the field of calibration device technology, specifically a calibration structure for an eye tracker height-adjustable desk. Background Technology

[0002] Eye trackers have wide applications in education, psychology research, and other fields. In relevant scenarios, height-adjustable desks for eye trackers provide users with flexible height adjustment to accommodate people of different heights and usage needs, ensuring the eye tracker is at a suitable height and position, thereby guaranteeing measurement accuracy and comfort. Such desks, to a certain extent, meet basic usage requirements and provide hardware support for the effective use of eye trackers.

[0003] However, most existing calibration structures use screws for repositioning and calibration, making them difficult to adapt to the many different specifications of eye trackers on the market. This limited compatibility greatly restricts the application range of the calibration structure. If users want to replace different models of eye trackers, they often need to replace the calibration structure again, which increases the cost of use and wastes time and resources. Utility Model Content

[0004] The purpose of this invention is to provide a calibration structure for an eye tracker-adjustable desk, in order to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a calibration structure for an eye-tracking height-adjustable desk, comprising an eye-tracking device and a mounting base, and further comprising:

[0006] Two sets of clamping rods are positioned at the lower end of the eye tracker and are distributed symmetrically in a mirror image.

[0007] The telescopic assembly is located at the lower end of the clamping rod. When the telescopic assembly moves the two clamping rods closer to each other, the limiting claw at the end of the clamping rod clamps the segment ball fixed at the lower end of the eye tracker. At the same time, the positioning rod connected to the telescopic assembly is inserted into the positioning holes on the side of the two sets of vertical plates fixed at the upper end of the mounting base, thereby fixing the telescopic assembly to the vertical plates.

[0008] As a further description of the above technical solution: the telescopic component includes a grooved plate disposed between two sets of vertical plates, and a cross slider is slidably installed in the groove of the grooved plate, the cross slider being fixed to the clamping rod.

[0009] As a further description of the above technical solution: a support rod is fixed at the upper end of the groove plate, and a groove block is fixed at the top of the support rod. The upper surface of the groove block is provided with an inner concave surface that fits into the bottom spherical surface of the link rod ball.

[0010] As a further description of the above technical solution: the cross slider is connected to a movable section rod on the side opposite to the clamping rod, the bottom end of the movable section rod is connected to an internal threaded block, a screw is threaded onto the internal threaded block, and the top end of the screw passes through the inner groove of the slot plate and is rotatably connected to the support rod.

[0011] As a further description of the above technical solution: the cross slider has a guide rod fixed on the side near the vertical plate, and a positioning plug is fixed at the end of the guide rod. The positioning plug can be inserted into the positioning holes on the side of the two sets of vertical plates.

[0012] As a further description of the above technical solution: the vertical plate is provided with a vertical groove, and the guide rod slides up and down along the inner side of the vertical groove.

[0013] In the above technical solution, the calibration structure for an eye tracker height-adjustable desk provided by this utility model has the following beneficial effects:

[0014] 1. The eye tracker's height-adjustable desk calibration structure uses a rotating screw to drive the corresponding components to work together. This not only allows for convenient angle adjustment of the eye tracker but also for overall height adjustment. It enables flexible calibration and fixation of the eye tracker at multiple angles and heights on the mounting frame, meeting the diverse needs of different users in different scenarios and improving the adaptability of the eye tracker.

[0015] 2. The eye tracker's height adjustment desk calibration structure uses a screw to drive the clamping rod to secure the joint ball, thus adjusting the angle. Simultaneously, it drives the guide rod and positioning rod to complete the height adjustment and positioning, avoiding the tedious operation of adjusting the angle and height separately, greatly improving calibration efficiency. Moreover, during the linkage adjustment process, the cooperation of each structure ensures the overall stability. The groove block's support for the joint ball, as well as the cooperation between the guide rod and the vertical groove, and the positioning rod and the positioning holes, ensure that the eye tracker can be firmly fixed in the required position after adjustment.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-4 This utility model provides a calibration structure for an eye tracker height-adjustable desk: it includes an eye tracker 1 and a mounting base 2, and further includes: two clamping rods 3, which are arranged at the lower end of the eye tracker 1 and are mirror-symmetrically distributed; a telescopic component 4, which is arranged at the lower end of the clamping rods 3. When the telescopic component 4 moves the two clamping rods 3 closer together, the limiting claws 5 at the ends of the clamping rods 3 clamp the segmented rod ball 6 fixed at the lower end of the eye tracker 1; the clamping rods 3 are close to each other, and the limiting claws 5 at the ends lock the segmented rod ball 6, thereby fixing the eye tracker 1. At the same time, the positioning rods 7 connected to the telescopic component 4 are inserted into the positioning holes on the sides of the two sets of vertical plates 8 fixed at the upper end of the mounting base 2, thereby fixing the telescopic component 4 to the vertical plates 8; the positioning rods 7 are inserted into the positioning holes on the sides of the vertical plates 8 to realize the connection and positioning of the telescopic component 4 and the vertical plates 8, and to adjust the height of the eye tracker.

[0025] In another embodiment of the present invention, preferably, the telescopic component 4 includes a groove plate 41 disposed between two sets of vertical plates 8. A cross slider 42 is slidably mounted in the groove of the groove plate 41. The cross slider 42 is fixed to the clamping rod 3. The groove plate 41 provides a sliding track for the cross slider 42. The cross slider 42 slides in the groove of the groove plate 41, and the cross slider 42 is connected to the clamping rod 3, so that the sliding of the cross slider 42 can drive the clamping rod 3 to move.

[0026] In another embodiment of the present invention, preferably, a support rod 9 is fixed to the upper end of the groove plate 41, and a groove block 10 is fixed to the top of the support rod 9. The upper surface of the groove block 10 is provided with an inner concave surface that fits into the bottom spherical surface of the link ball 6. The support rod 9 supports the groove block 10, and the inner concave surface on the groove block 10 fits into the bottom spherical surface of the link ball 6, which supports the link ball 6 and improves the stability of the eye tracker 1 when it is fixed.

[0027] In another embodiment of the present invention, preferably, the cross slider 42 is connected to a movable section rod 43 on the side opposite to the clamping rod 3. The bottom end of the movable section rod 43 is connected to an internal threaded block 44. A screw 45 is threaded onto the internal threaded block 44. The top end of the screw 45 passes through the inner groove of the slot plate 41 and is rotatably connected to the support rod 9. When the screw 45 is rotated, since the screw 45 is threaded onto the internal threaded block 44, the rotation of the screw 45 drives the internal threaded block 44 to move. The internal threaded block 44 drives the movable section rod 43 to move. The movable section rod 43 drives the cross slider 42 to slide in the inner groove of the slot plate 41.

[0028] In another embodiment of this utility model, preferably, the cross slider 42 has a guide rod 46 fixed on the side near the vertical plate 8, and a positioning rod 7 is fixed at the end of the guide rod 46. The positioning rod 7 can be inserted into the positioning holes on the side of the two sets of vertical plates 8. The vertical plate 8 is provided with a vertical groove, and the guide rod 46 slides up and down along the inner side of the vertical groove. When the cross slider 42 slides, it drives the guide rod 46 to move, and the positioning rod 7 at the end of the guide rod 46 moves accordingly and is inserted into the positioning holes on the side of the vertical plate 8. At the same time, the guide rod 46 slides in the vertical groove of the vertical plate 8 to ensure the stability and positioning accuracy of the telescopic component 4.

[0029] During operation, the operator rotates the screw 45. Since the screw 45 is threadedly connected to the internal threaded block 44 and the top of the screw 45 is rotatably connected to the support rod 9, as the screw 45 rotates, the internal threaded block 44 drives the movable section rod 43 to move. The movable section rod 43 drives the cross slider 42 connected to it to slide in the groove of the slot plate 41. Since the cross slider 42 is fixed to the clamping rod 3, the sliding of the cross slider 42 drives the two clamping rods 3 to move closer to each other. When the clamping rods 3 move closer to each other to a certain extent, the limiting claw 5 at the end of the clamping rod 3 clamps the section rod ball 6 fixed at the lower end of the eye tracker 1, and the angle of the eye tracker 1 can be adjusted by using the section rod ball 6.

[0030] While clamping rod 3 clamps the joint rod ball 6, the guide rod 46 fixed on the side of cross slider 42 near the vertical plate 8 moves with the sliding of cross slider 42. The positioning insert 7 fixed at the end of the guide rod 46 is inserted into the positioning holes on the side of the two sets of vertical plates 8. The guide rod 46 slides up and down along the inner side of the vertical groove set on the vertical plate 8, which further ensures the movement stability and positioning accuracy of telescopic component 4. Through the above operation, the overall height of the eye tracker is adjusted, and the calibration and fixing of the entire eye tracker on the mounting base is completed in conjunction with the angle adjustment.

[0031] In addition, during the entire calibration and fixation process, the concave surface on the upper surface of the groove block 10, which fits against the bottom spherical surface of the link ball 6, provides support for the link ball 6 and enhances the stability of the eye tracker fixation.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
