Description

Technical Field

[0001] This invention belongs to the field of posture correction technology, and more specifically, relates to an angle-adjustable anti-myopia bracket. Background Technology

[0002] During daily studies, teenagers and children often neglect their posture because they are so focused on the learning content. Unconsciously, their bodies lean forward, drastically shortening the distance between their eyes and the desk. When this distance is too close, the eyes have to exert more effort to focus. Prolonged periods in this position easily lead to eye fatigue, damaging vision and ultimately causing amblyopia or myopia, which is clearly detrimental to the physical and mental health of teenagers and children. Therefore, how to effectively prevent myopia in teenagers and children has always been a major concern for parents and teachers.

[0003] Currently, a large number of myopia prevention products have appeared on the market, such as corrective desks and chairs, and eye-protection lamps. However, most corrective desks and chairs are bulky, inconvenient to carry, and assembling them is relatively cumbersome; at the same time, they are expensive and have low cost-effectiveness. Eye-protection lamps mainly address the lighting environment, and their corrective effect on myopia caused by poor posture is relatively limited. Therefore, designing a low-cost, portable, and easy-to-operate myopia prevention product has significant practical significance and application value.

[0004] A search revealed that patent CN105661919A discloses a myopia prevention bracket; and patent CN105661920A discloses a myopia prevention bracket that can be fixed in place.

[0005] In the aforementioned application, the support rod is fixed to the inner side of a desk or school desk via suction cups or a base. When the support is adjusted to a height that supports the head, the frame helps prevent excessive head drooping while reading or writing, thus preventing myopia caused by excessive close-up work. However, the aforementioned anti-myopia bracket only allows for vertical height adjustment and cannot adjust the angle of the bracket, making it difficult to adapt to different users' body shapes and usage habits. Summary of the Invention

[0009] In some embodiments, the connecting assembly has rotating shafts on both sides of its end, and the first connecting block and the second connecting block have assembly holes for the rotating shafts to engage; or, The first connecting block and the second connecting block are provided with rotating shafts, and the connecting assembly is provided with assembly holes for the rotating shafts to be inserted.

[0010] In some embodiments, the first connecting block and the second connecting block are further provided with locking holes, and the locking holes are equipped with locking elements.

[0011] In some embodiments, the locking element is a locking bolt, and the connecting assembly is provided with a sliding groove; The free end of the locking bolt passes sequentially through the locking hole and sliding groove on one side of the first connecting block and the locking hole on the other side of the first connecting block, and is then fitted with a locking nut.

[0012] In some embodiments, the inner sidewalls of the first connecting block and the second connecting block are provided with limiting grooves, and the connecting assembly is provided with limiting protrusions that cooperate with the limiting grooves. When the first connecting block, the second connecting block and the connecting assembly are locked together, the limiting protrusion is engaged in the limiting groove.

[0013] In some embodiments, the clamping component includes a clamping seat; wherein the clamping seat is an open structure formed by a top plate, a bottom plate, and a side plate; A locking element is connected to the bottom plate or top plate, and the free end of the locking element extends into the cavity of the clamping assembly and is connected to a clamping block.

[0014] In some embodiments, the connecting assembly includes a first rod and a second rod that are nested together; and the two rods are provided with a plurality of adjustment holes along their axial direction, and the two rods are locked and released by a locking member.

[0015] In some embodiments, the support member is provided with a pad; wherein the pad and the second connecting block are respectively disposed on opposite sides of the support member.

[0016] In some embodiments, the pad is a soft pad or an air cushion; the clamping surface of the clamping block is provided with a soft pad.

[0017] In some embodiments, the first connecting block and the clamping seat, the second connecting block and the support member, and the pad block and the support member are all detachably connected.

[0018] In some embodiments, the anti-myopia bracket further includes an intelligent learning platform, which includes a mounting box and a camera and a projector mounted on the mounting box; wherein the mounting box is rotatably mounted on a support component or a connecting component via a transition component.

[0019] Beneficial effects Compared with the prior art, the beneficial effects of the present invention are as follows: (1) An angle-adjustable anti-myopia bracket of the present invention forms a clamping space on both the clamping component and the supporting component, and the two ends of the connecting component are respectively rotated and locked in the corresponding clamping space, thereby allowing relative rotation between the clamping component, the supporting component and the connecting component, and each rotation operation is relatively independent.

[0025] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0026] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] As mentioned in the background section, existing anti-myopia brackets often only allow for height adjustment, making it difficult to adapt to different users' body shapes and usage habits. Specifically, the angle requirements of the support components vary depending on the user's activity, such as writing, reading, or drawing. A fixed angle design may cause discomfort in certain situations and could even lead to new posture problems due to forcing the user to adapt to the bracket's angle.

[0028] Therefore, the present invention aims to provide an angle-adjustable anti-myopia support frame to solve the problem that the angle of existing anti-myopia support frames is relatively fixed, resulting in poor applicability.

[0029] The present invention will be further described below with reference to specific embodiments.

[0030] Example 1 refer to Figure 1 As shown, an adjustable anti-myopia bracket according to this embodiment includes a connecting component 200 and a clamping component 100 and a supporting component 300 respectively disposed at both ends of the connecting component 200. The clamping component 100 is used to fix the entire anti-myopia bracket to the desk, providing a stable mounting base. The supporting component 300 is used to provide auxiliary support for the user to prevent excessive head drooping, thereby preventing myopia caused by excessive close-up work. Both the clamping component 100 and the supporting component 300 are rotatably mounted on the connecting component 200 to facilitate adjustment of their respective angles.

[0031] Specifically, such as Figure 2 , Figure 4 As shown, the clamping assembly 100 includes a clamping component 110 and a pair of first connecting blocks 120 disposed on the clamping component 110, with a first clamping space 130 formed between the two first connecting blocks 120. One end of the connecting assembly 200 is inserted into the first clamping space 130 and rotatably connected to the first connecting block 120 to adjust the relative angle between the clamping component 110 and the connecting assembly 200.

[0032] Meanwhile, the support assembly 300 includes a support member 310 and a pair of second connecting blocks 320 disposed on the support member 310, with a second clamping space 330 formed between the two second connecting blocks 320. The other end of the connecting assembly 200 is inserted into the second clamping space 330 and rotatably connected to the second connecting block 320 to adjust the relative angle between the support member 310 and the connecting assembly 200.

[0033] This embodiment of an adjustable myopia prevention bracket creates a clamping space on both the clamping component 100 and the support component 300. The two ends of the connecting component 200 are rotatably secured within their respective clamping spaces. This allows for relative rotation between the clamping component 100, the support component 300, and the connecting component 200, with each rotation operation being relatively independent. This design allows for flexible adjustment of the angles of the clamping component 100 and the support component 300 to accommodate different user body shapes and usage habits. Simultaneously, the limiting effect of the clamping spaces ensures stability during rotation.

[0034] In some implementations, the support component 300 may be designed with a telescopic structure to facilitate height adjustment, thereby further expanding the product’s applicability.

[0035] Specifically, refer to Figure 3 As shown, the connecting assembly 200 includes a first rod 210 and a second rod 220 that are nested together, and both rods have a plurality of adjusting holes 212 along their axial direction. A locking element 400 is provided at each adjusting hole 212. When the height between the first rod 210 and the second rod 220 is adjusted to the desired position, an adjusting screw passes through the corresponding adjusting hole 212 and is fitted with a locking nut to achieve a locking operation between the two rods.

[0036] Furthermore, rotating shafts 230 are provided on both sides of the ends of the two rods that are far apart from each other. At the same time, the first connecting block 120 and the second connecting block 320 are provided with mounting holes 121 for the rotating shafts 230 to be inserted, so as to realize the rotational connection between the first connecting block 120, the second connecting block 320 and the rods.

[0037] Of course, a rotating shaft 230 is provided on the inner side of the first connecting block 120 and the second connecting block 320; and assembly holes 121 are provided on both sides of the ends of the first rod 210 and the second rod 220 for the rotating shaft 230 to be inserted, which can also realize the rotational connection between the rod and the corresponding connecting block.

[0038] like Figure 2 , Figure 3As shown, in some other embodiments, the first connecting block 120 and the second connecting block 320 are also provided with locking holes 122, and locking members 400 are provided at the locking holes 122. At the same time, the first connecting block 120 and the second connecting block 320 are provided with sliding grooves 211 for the locking members 400 to pass through at corresponding positions.

[0039] Specifically, the locking element 400 is a locking bolt; the sliding groove 211 is an arc-shaped groove centered on the rotating shaft 230 on the corresponding rod. The free end of the locking bolt passes through the locking hole 122 on one side of the first connecting block 120, the sliding groove 211, and the locking hole 122 on the other side of the first connecting block 120 in sequence, and is then fitted with a locking nut.

[0040] This design not only enables the locking and unlocking of the first connecting block 120 and the second connecting block 320, but also allows the locking bolt and the arc groove to cooperate and guide and limit the rotation of the clamping assembly 100 and the support assembly 300. Combined with the limiting effect of the clamping space, this further ensures the stability of the clamping assembly 100 and the support assembly 300 during rotation.

[0041] In some optional embodiments, the inner sidewalls of the first connecting block 120 and the second connecting block 320 are provided with limiting grooves 123; at the same time, the connecting assembly 200 is provided with limiting protrusions 240 that cooperate with the limiting grooves 123. When the first connecting block 120, the second connecting block 320 and the connecting assembly 200 are locked together, the limiting protrusions 240 can be engaged into the limiting grooves 123 to further restrict the relative rotation between the first connecting block 120, the second connecting block 320 and the connecting assembly 200, ensuring that the first connecting block 120 and the second connecting block 320 can be more stably stationed in the target position.

[0042] refer to Figure 2 As shown, in one embodiment of the clamping component 110, the clamping component 110 includes a clamping seat 111, which is an open structure formed by a top plate, a bottom plate, and a side plate. Meanwhile, a locking member 400, such as a locking screw, is connected to the bottom plate. The free end of the locking screw extends into the cavity of the clamping assembly 100 and is connected to a clamping block 112, thereby forming a clamping and locking space between the clamping block 112 and the top plate.

[0043] During assembly, the clamping base 111 is inserted into the side of the desk using the open side; at this time, the side of the desk is located within the aforementioned clamping and locking space; then, the locking member 400 is rotated to move the clamping block 112 upward and press it against the lower surface of the desk to ensure the stability of the connection between the clamping base 111 and the desk. Meanwhile, since the clamping base 111 is inserted from the side of the desk, it does not occupy too much space on the desk.

[0044] Furthermore, to prevent the clamping component 110 from scratching the surface of the desk, a soft pad may be placed on the top of the clamping component 110 and the bottom of the top plate.

[0045] Of course, the locking element 400 can also be installed on the top plate to press down on the upper surface of the desk. Alternatively, the clamping component 110 can directly use a spring clip from the prior art; no specific limitation is made here.

[0046] like Figure 4 As shown, in some embodiments, the support member 310 is further provided with a pad 340. The pad 340 and the second connecting block 320 are respectively disposed on opposite sides of the support member 310. Preferably, the pad 340 can be a soft pad or an air cushion.

[0047] Furthermore, to facilitate the disassembly and carrying of the entire bracket, the various components of this embodiment of the angle-adjustable anti-myopia bracket are detachably connected, for example, between the first connecting block 120 and the clamping seat 111, between the second connecting block 320 and the support member 310, and between the pad 340 and the support member 310.

[0048] It is worth mentioning that the aforementioned detachable connections are existing technologies, such as bolts and snap-fit ​​connections, and will not be elaborated further here.

[0049] Example 2 This embodiment of the adjustable anti-myopia bracket, based on the above embodiment, also includes an intelligent learning platform 500, which mainly includes hardware components and a processor component.

[0050] Specifically, such as Figure 1 , Figure 5 , Figure 6 As shown, the hardware includes components such as a mounting box 510, a transition component 520, a camera 530, and a projector 540. The mounting box 510 is rotatably mounted on the front (the side facing away from the user) of the support member 310 or the first rod 210 via the transition component 520, so as to facilitate the adjustment of the angle of the mounting box 510 and its components.

[0051] Camera 530 is positioned on the side of mounting box 510 away from support member 310 for collecting information from users or the environment. Projector 540 is also positioned on the side of mounting box 510 away from support member 310 for projecting information onto a desktop or wall to create a virtual screen.

[0052] The processor (not shown in the figure) is located inside the mounting box 510. It supports AI interaction. The processor processes the user's voice input and outputs the corresponding results. Finally, the voice output is delivered through the speaker or the graphic display is shown through the projector 540.

[0053] It should be noted that the rotatable connection between the aforementioned transition component 520 and the mounting box 510 can refer to the connection structure between the first connecting block 120 and the first rod 210, or can adopt existing structures such as universal joints, which will not be elaborated here.

[0054] The intelligent learning platform 500 also includes a microphone and a speaker (not shown in the figure). The microphone, which can be mounted on the support 310 or the mounting box 510, is used to collect the user's voice commands. The speaker, which can be mounted on the support 310 or the mounting box 510, is used to provide voice feedback and clear sound quality.

[0055] This embodiment of an angle-adjustable anti-myopia bracket, equipped with an intelligent learning platform 500, can effectively improve the user's learning efficiency. However, it should be noted that the electrical components and processor components in the aforementioned hardware are all existing technologies and are not specifically limited here.

[0056] Furthermore, based on the above, the specific hardware configuration of the intelligent learning platform 500 of the present invention is as follows: 1) The camera 530 is a high-definition camera used to collect information such as the user's facial expressions, gestures, and surrounding environment, and supports functions such as face recognition and motion capture.

[0057] 2) The projector 540 is a mini projector that can project information onto surfaces such as desktops and walls to achieve functions such as virtual screens and AR interaction.

[0058] 3) The speaker is a high-fidelity speaker, providing clear sound quality and supporting functions such as voice broadcast, music playback, and voice calls.

[0059] 4) Multiple microphones form a microphone array to achieve far-field voice acquisition, noise reduction, echo cancellation and other functions, and improve the voice interaction experience.

[0060] 5) It is also equipped with sensors, including gravity sensors and gyroscopes, to sense user posture and user actions.
