Description

Technical Field

[0001] This utility model relates to the field of eye training device technology, specifically to a mother-daughter structure for an eye training device. Background Technology

[0002] With the increase in students' schoolwork from a young age, and the harm caused by electronic products such as televisions, computers, and mobile phones, myopia among students has become very common. In order to alleviate the problem of myopia among students without causing the trouble of surgery, people have developed vision training and recovery devices. These devices can slowly adjust myopia and other problems by training the eye muscles.

[0003] Currently, existing eye training devices and related eye training components are inconvenient to carry due to the limitations of their supports. Removing the support structure makes it difficult for users to maintain a standard sitting posture during eye training, which greatly reduces the training effect. Therefore, they do not meet the current needs. To address this, we propose a mother-daughter structure for eye training devices. Utility Model Content

[0004] This utility model provides a mother-daughter structure for an eye training device, which has the advantages of being able to be disassembled for easy carrying, and also being able to be assembled for standardized training, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a mother-daughter structure for an eye training device, including a mother training device and a base. The base is provided with a connecting shaft for connecting the mother training device. The top of the connecting shaft is provided with an assembly plate. The mother training device is mounted on the connecting shaft through the assembly plate. The assembly plate is provided with a positioning arm. The bottom of the mother training device is provided with a locking cavity for the positioning arm to be inserted. The positioning arm and the locking cavity are assembled in a transition fit. The bottom of the mother training device is provided with a positioning cavity at the front end of the locking cavity. The positioning arm and the positioning cavity are assembled in a clearance fit.

[0006] In this invention, the training device and the base adopt a detachable mother-daughter structure, which allows the training device to be removed and carried separately, or it can be assembled with the base using an assembly plate. Compared with a single training device or a training device fixed to a support, this structure combines the advantages of both, namely, improving convenience while enabling standardized eye training.

[0007] As an optional structure of the eye training device described in this utility model, the assembly plate is provided with a tail ramp on the side away from the human body, and the tail ramp is inclined downward on the side away from the assembly plate.

[0008] As an optional structure of the eye training device described in this utility model, the top of the base is provided with a shaft bracket that is pinned to both ends of the connecting shaft, and the connecting shaft pins the mounting plate between the two shaft brackets.

[0009] As an optional structure of the eye training device described in this utility model, the side walls of the assembly plate and the shaft frame that are in contact with each other are provided with friction-increasing stripes, which increase the friction between the assembly plate and the shaft frame.

[0010] As an optional structure of the eye training device described in this utility model, the shaft frame is provided with assembly cavities at both ends corresponding to the connecting shaft, the assembly points at both ends of the connecting shaft are located in the assembly cavities, and the assembly cavities are provided with shielding covers.

[0011] As an optional structure of the eye training device described in this utility model, the training device mother unit has a built-in battery, and the bottom of the training device mother unit is provided with a battery cover for replacing the battery.

[0012] As an optional structure of the eye training device described in this utility model, at least half of the battery cover is located between the two locking cavities.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this type of eye training device using a mother-daughter structure, the training device mother unit is connected and assembled through a set assembly plate. Moreover, when the positioning arm at the top is inserted into the locking cavity, it will first pass through the positioning cavity to correct and position it, thereby avoiding the positioning arm from being installed at an angle and causing jamming.

[0015] 2. In this type of eye training device with a mother-daughter structure, the positioning cavity can also play a protective role when the mother unit of the training device is removed. When the positioning arm disengages from the locking cavity, it will enter the positioning cavity. At this time, the mother unit of the training device and the assembly plate still maintain a supported state, thereby avoiding the problem of the mother unit of the training device slipping out of your hand and falling to one side when removing the mother unit due to excessive force.

[0016] 3. In this type of eye training device with a mother-daughter structure, the connecting shaft and the assembly plate are connected by pins through a set shaft frame, and resistance-increasing stripes are set between the contact surfaces of the shaft frame and the assembly plate, so that the mother unit of the training device can rotate on the base through the connecting shaft and the assembly plate and stop at a suitable angle, so as to facilitate standardized training.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: This example aims to facilitate the solution of how to enable the training machine 2 to be used independently. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3A mother-daughter structure for an eye training device includes a mother unit 2 and a base 3. The mother unit 2 has a built-in battery. The base 3 is provided with a connecting shaft 1 for connecting the mother unit 2. The top of the connecting shaft 1 is provided with an assembly plate 10. The mother unit 2 is mounted on the connecting shaft 1 via the assembly plate 10.

[0026] In this embodiment, the training device 2 can be carried and used independently, and the training device 2 with a built-in battery can eliminate the hassle of connecting to a power strip.

[0027] Example 2 aims to facilitate convenient and quick use of the training device 2 in both independent and auxiliary support states, and to simplify the disassembly and assembly steps between the training device 2 and the base 3. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 2 , Figure 3 , Figure 4 and Figure 5 The assembly plate 10 is provided with a positioning arm 100. The bottom of the training machine mother unit 2 is provided with a locking cavity 21 for the positioning arm 100 to be inserted. The assembly method between the positioning arm 100 and the locking cavity 21 is a transition fit. When the positioning arm 100 is inserted into the locking cavity 21, the connection between the locking cavity 21 and the positioning arm 100 is made by a transition fit, which makes the connection more stable. The bottom of the training machine mother unit 2 is provided with a positioning cavity 20 at the front end of the locking cavity 21. The assembly method between the positioning arm 100 and the positioning cavity 20 is a clearance fit. The positioning arm 100 enters the locking cavity 21 after passing through the positioning cavity 20, thereby avoiding the positioning arm 100 from being tilted during assembly, so as to ensure smooth assembly and accurate installation.

[0028] The top of the base 3 is provided with a shaft bracket 30 that is pinned to both ends of the connecting shaft 1. The side walls of the mounting plate 10 and the shaft bracket 30 that are in contact with each other are provided with resistance-increasing stripes 101. The resistance-increasing stripes 101 increase the friction between the mounting plate 10 and the shaft bracket 30. When the mounting plate 10 is rotated, the thrust overcomes the friction between the mounting plate 10 and the shaft bracket 30 after the resistance-increasing stripes 101 have increased, so that it can rotate. When the thrust disappears, the friction between the mounting plate 10 and the shaft bracket 30 after the resistance-increasing stripes 101 have increased will maintain the angle between the mounting plate 10 and the shaft bracket 30, thereby adjusting the angle of the training instrument mother machine 2 for standardized eye training.

[0029] The assembly plate 10 has a tail ramp 11 on the side away from the human body. The tail ramp 11 is installed on the side away from the human body, so that when the training instrument mother unit 2 is disassembled and assembled, the end that is in contact with the human eye can face outward, thereby reducing collision and protecting the training instrument mother unit 2. The side of the tail ramp 11 away from the assembly plate 10 is inclined downward.

[0030] In this embodiment: the training instrument mother unit 2 is connected and assembled through the assembly plate 10. When the positioning arm 100 on the top of the assembly plate 10 is inserted into the locking cavity 21, it will first pass through the positioning cavity 20, thereby correcting the position and angle of the assembly plate 10. Moreover, when the positioning arm 100 is disengaged from the locking cavity 21, it will enter the positioning cavity 20. At this time, the training instrument mother unit 2 and the assembly plate 10 still maintain a supported state, thereby playing a protective role when the training instrument mother unit 2 is removed. Furthermore, the tail ramp 11 allows the user to apply force, thereby enabling convenient and quick disassembly and installation of the training instrument mother unit 2.

[0031] It should be noted that in the clearance fit assembly method between the positioning arm 100 and the positioning cavity 20, the cross-sectional shape of the positioning arm 100 should be smaller than that of the positioning cavity 20 to allow for smooth insertion and removal. In the transition fit assembly method between the positioning arm 100 and the locking cavity 21, the size relationship between the cross-sectional shape of the positioning arm 100 and the cross-sectional shape of the locking cavity 21 needs to be determined according to the material of the wall of the locking cavity 21. If the deformation capacity of the locking cavity 21 is poor, the cross-sectional shapes of the two should match each other. If the deformation capacity of the locking cavity 21 is good, the cross-sectional shape of the positioning arm 100 can be slightly larger than that of the locking cavity 21.

[0032] Example 3: This example aims to improve the aesthetics of the mother-daughter unit structure of the eye training device. This example is an improvement based on Example 1. For details, please refer to... Figure 4 , Figure 5 and Figure 6 The bottom of the training machine 2 is provided with a battery cover 200 for replacing the battery. At least half of the cover of the battery cover 200 is located between two locking cavities 21. The connecting shaft 1 pins the mounting plate 10 between two shaft brackets 30. The shaft brackets 30 are provided with mounting cavities 300 corresponding to the two ends of the connecting shaft 1. The mounting points at both ends of the connecting shaft 1 are located in the mounting cavities 300. The mounting cavities 300 are provided with shielding covers 301.

[0033] In this embodiment, the shaft bracket 30 is pin-connected to the connecting shaft 1, and the two ends of the connecting shaft 1 are assembled in the assembly cavity 300 with the shielding cover 301, thereby hiding the assembly marks. Furthermore, the shaft bracket 30 and the base 3 are integrated into one structure, which has stronger strength and higher stability, thereby increasing the service life of the base 3.

[0034] The working principle of this utility model is as follows: First, the training instrument mother unit 2 can be installed on the base 3 as needed for standardized eye training. During installation, the base 3 is positioned by means of the tail ramp 11, and the end of the training instrument mother unit 2 used for eye training is adjusted accordingly.

[0035] Subsequently, the training instrument mother unit 2 is connected and assembled via the assembly plate 10. The positioning arm 100 of the assembly plate 10 first passes through the positioning cavity 20. The positioning cavity 20 corrects and positions the assembly plate 10 through the positioning arm 100 to prevent the assembly plate 10 from tilting. With the push of the thrust, the positioning arm 100 enters the locking cavity 21. When the positioning arm 100 is fully entered into the locking cavity 21, the connection between the training instrument mother unit 2 and the base 3 is completed. After the connection is completed, the training instrument mother unit 2 can be directly lifted or pressed down for angle adjustment.

[0036] Then, when the training instrument mother unit 2 needs to be used or carried alone, the training instrument mother unit 2 can be pushed in the opposite direction by the tail ramp 11. When the positioning arm 100 disengages from the locking cavity 21, it will enter the positioning cavity 20. At this time, the training instrument mother unit 2 and the assembly plate 10 still maintain a supported state, thereby avoiding the problem of the training instrument mother unit 2 being bumped or knocked when removing the training instrument mother unit 2 due to excessive force.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
