Description

Technical Field

[0001] The utility model relates to the technical field of eye auxiliary training equipment, in particular to a children's eye tracking training device. Background Art

[0002] Tracking training is also called visual concentration training. Most children are born with eyes that cannot fully focus on an object, so tracking training is needed to allow the child's line of sight to move with the object. This helps the child's vision development and improves observation attention.

[0003] According to a children's eye tracking training device disclosed in Chinese patent publication number CN217286440U, the patent adjusts the swing amplitude of the swing arm by adjusting the adjustment block and the limit spring away from or close to the rack, so that the training amplitude is changed, which is convenient for different adaptive training for different children. In actual use, the patent needs to use a limit spring as the power part of the swing arm. By giving the limit spring an initial force and making it rebound according to the characteristics of the spring, the swing arm can swing normally. After applying the initial force to the spring and then releasing it, the amplitude of the first swing will be very large and the swing rate will be fast, which is not conducive to children's tracking. At the same time, in the subsequent rebound action, the amplitude will become smaller and smaller, and a fixed amplitude and swing rate cannot be guaranteed, resulting in a certain room for improvement in its practicality.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 3The utility model provides a technical solution: a children's eye tracking training device, comprising a mounting shell 1 with an opening at the bottom, a swinging assembly 200 for adjusting the swinging amplitude is mounted on the inner side of the mounting shell 1, and a training assembly 300 for eye tracking training is mounted on the end of the swinging assembly 200; through the coordinated use between the swinging assembly 200 on the inner side of the mounting shell 1 and the training assembly 300 on the outer side, the swinging amplitude and speed can be adjusted while ensuring that the amplitude and speed remain unchanged during the training process, and the adjustment method is very simple, which is convenient for the operator to complete easily, and the height of the swinging structure can also be adjusted, so that its applicability can be further improved, so that eye tracking training for different children can be effectively carried out, thereby effectively improving the practicality of the children's eye tracking training device.

[0024] It should be noted that two first mounting parts 401 are fixedly installed on the top of the mounting shell 1, and two second mounting parts 402 are fixedly installed on the back of the mounting shell 1. The first mounting parts 401 can be passed through by bolts and other connecting parts, and can be hoisted, so that the mounting shell 1 can be stably installed. The end of the second mounting part 402 extends to the back side of the equipment box 205, which can be fixed by the rod-shaped support structure. Specifically, the rod-shaped support structure is a support rod with a through hole on the top. By passing bolts and other connecting parts between the through hole and the inner side of the second mounting part 402, and then fixing it with nuts, the mounting shell 1 can be fixed, so that it can be installed on the ground through the support rod, and can also be installed on the wall or table, which facilitates the normal fixing work of the mounting shell 1.

[0025] In this embodiment, the swing assembly 200 is a structure for adjusting the swing amplitude of the training structure.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the swing assembly 200 includes a rotating shaft 201 rotatably connected to the inner side of the mounting shell 1 through a bearing, a turntable 202 fixed to the outside of the rotating shaft 201, a rotating rod 203 rotatably connected to the inner side of the mounting shell 1 through a bearing, a swing plate 204 fixed to the outside of the rotating rod 203, an equipment box 205 fixed to the outside of the mounting shell 1, a driving mechanism 206 fixedly installed on the inner side of the equipment box 205, a pushing hole 207 opened on the front side of the swing plate 204, a plurality of threaded grooves 208 opened on the front side of the turntable 202 and arranged vertically at equal distances, a pushing column 209 abutting against the front side of the turntable 202, an abutting groove 210 opened on the front side of the pushing column 209, and a hexagon socket bolt 211 inserted into the inner side of the abutting groove 210 and with the end portion passing through the front side of the pushing column 209.

[0027] It should be noted that the output shaft of the driving mechanism 206 passes through the back side of the mounting shell 1 and is fixedly connected to the end of the rotating shaft 201, so that the driving mechanism 206 can drive the rotating shaft 201 to rotate, wherein the driving mechanism 206 can be a servo motor, and the transmission speed can be changed through a preset program. The number of thread grooves 208 is at least three. Specifically, the number of thread grooves 208 opened on the front of the turntable 202 in this application is three. The volume of the mounting shell 1 and the diameter area of ​​the turntable 202 can be increased according to actual usage requirements, so as to open more thread grooves 208 to facilitate multi-level adjustment.

[0028] In addition, the outer side of the pushing column 209 and the inner side of the pushing hole 207 are both smooth. The pushing column 209 is a cylinder, and the outer side of the pushing column 209 fits with the inner side of the pushing hole 207, so that the pushing column 209 can smoothly push the inner wall of the pushing hole 207. Among them, when the pushing column 209 is located at the position of the thread groove 208 on the side farthest from the rotating shaft 201, the pushing hole 207 can still allow the pushing column 209 to perform normal circular motion.

[0029] At the same time, the hexagon socket bolt 211 can be threadedly connected to the inner side of the thread groove 208. At this time, the end face of the hexagon socket bolt 211 abuts against the inner side of the abutment groove 210, so that the hexagon socket bolt 211 can play a role of abutment and limitation on the push column 209 after the threaded connection. When loosening or tightening the hexagon socket bolt 211, you can use your hand to pinch the push column 209 and press it, so that the push column 209 can remain stable in this state, making it easier to rotate the hexagon socket bolt 211.

[0030] In this embodiment, the training component 300 is a structure for performing tracking training on children's eyes.

[0031] like Figure 1 and Figure 2 As shown, the training component 300 includes an adjusting rod 301 slidably connected to the inside of the swing plate 204, a connecting rod 302 fixed to the bottom end of the adjusting rod 301, two limit plates 303 respectively fixed to the outside of the connecting rod 302 close to the adjusting rod 301 and the outside of the swing plate 204 close to the adjusting rod 301, a hand screw 304 passed through and threadedly connected to the front of the swing plate 204, a mounting tube 305 detachably connected to the outside of the bottom end of the connecting rod 302, and a training piece 306 fixed to the outside of the mounting tube 305.

[0032] It should be noted that an adjustment slot is provided at the bottom of the swing plate 204 for the adjustment rod 301 to be inserted and moved, so that the adjustment rod 301 can slide on the inner side of the adjustment slot, and the end of the hand screw 304 abuts against the front side of the adjustment rod 301, so that the hand screw 304 can abut and limit the adjustment rod 301 and complete the position positioning of the adjustment rod 301.

[0033] In addition, the limit plate 303 can facilitate limiting the position of the connecting rod 302 during the sliding process, and can also provide certain support for the operator's hands, so as to facilitate the normal adjustment of the movement work. The mounting tube 305 can be connected to the outer side of the connecting rod 302 by a screw connection, so that it can be replaced, so as to synchronously drive the training piece 306 to be replaced. The training piece 306 can be a plush ball, a small bell, etc., which is convenient for replacement according to the children's preferences.

[0034] It should also be noted that a rechargeable power supply and a main controller are fixedly installed on the outside of the mounting shell 1, which can provide electrical energy to the driving mechanism 206 and control it, and the electrical components appearing in the text are electrically connected to the main controller and the rechargeable power supply. The provision of power is common knowledge in the field. The main controller can be a conventional known device such as a programmable PLC controller for control, which can be achieved through simple programming by technicians in this field. They are all existing publicly available power connection technologies and will not be described in detail in the text.

[0035] The working principle of the above embodiment is:

[0036] When conducting eye tracking training for children, according to actual training needs, loosen the hand screw 304, extend or shorten the part of the adjustment rod 301 located outside the swing plate 204, and then lock the position of the adjustment rod 301 by tightening the hand screw 304, loosen the hexagon socket bolt 211, and move the push column 209 out from the side of the fitting turntable 202. By adjusting the distance between the push column 209 and the side of the rotating shaft 201, the circular motion trajectory of the push column 209 can be changed, thereby changing the swing amplitude of the swing plate 204. After the push column 209 is moved, the hexagon socket bolt 211 is tightened. 1 is inserted into the inner side of the abutment groove 210, and the hexagon socket bolt 211 is tightened to be threadedly connected with the inner side of the corresponding thread groove 208. The positioning of the push column 209 is completed by the abutment and limiting between the end face of the hexagon socket bolt 211 and the abutment groove 210. The driving mechanism 206 is started to drive the rotating shaft 201 to rotate, so that the turntable 202 rotates, and then drives the push column 209 to perform a circular motion. During the motion, the inner wall of the pushing hole 207 is pushed to make the swing plate 204 perform a reciprocating swing motion, and then the training piece 306 is swung, so that it can perform eye tracking training for children.

[0037] Compared with the existing technology, the children's eye tracking training device, through the coordinated use between the swing component 200 on the inner side of the installation shell 1 and the training component 300 on the outer side, can adjust the swing amplitude and rate while ensuring that the amplitude and rate remain unchanged during the training process. At the same time, the adjustment method is very simple, which is convenient for the operator to complete easily. The height of the swing structure can also be adjusted, so that its applicability can be further improved, making it convenient for different children's eye tracking training to be effectively carried out, thereby effectively improving the practicality of the children's eye tracking training device, and solving the problem that the existing children's eye tracking training device has too large an initial swing amplitude and a fast rate, and cannot maintain a fixed amplitude and rate, which is not conducive to the normal progress of children's eye tracking training.
