Description

Technical Field

[0001] This invention belongs to the field of learning assistance technology, specifically relating to a portable learning data acquisition device. Background Technology

[0002] For primary and secondary school students, their daily learning state is a crucial issue that cannot be ignored. A good learning state can improve concentration and learning efficiency. A clear indicator of a good learning state is the correctness of one's posture. Correct posture makes others perceive that the person is focused and attentive. Incorrect posture, on the other hand, can not only lead to poor concentration and affect learning efficiency, but more seriously, it can also affect physical health. Studies have shown that students who tilt their heads forward and hold books too close to their eyes can affect their vision and are likely to develop myopia. Poor posture and a habit of slouching not only affect a student's image and temperament, but also hinder normal development and induce various diseases such as scoliosis, cervical spondylosis, and lumbar spondylosis.

[0003] Some students' poor posture is often unconscious, but over time it naturally becomes a habit, thus affecting their learning. For teachers, it's virtually impossible to simultaneously monitor the learning status and posture of dozens of students while lecturing from the podium. Parents, on the other hand, can only occasionally check on their children's studies and cannot constantly monitor their posture. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a learning data collection device applicable to primary and secondary school students, which can collect students' learning status data during class, enabling teachers to make targeted improvements to students' posture and learning status according to specific circumstances.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable learning data acquisition device, comprising: a first housing and a second housing, the first housing and the second housing being connected by a connector, both the first housing and the second housing being provided with wearable components that can be worn on the body, one end of the connector being connected to a sensing component, the sensing component being located inside the first housing and the connector being able to move the sensing component, and a cloud platform being provided inside the second housing.

[0006] A further technical solution of the present invention is that the connecting member includes a slide rod, and a slide groove is provided inside the second housing, and the slide rod can slide inside the slide groove.

[0007] A further technical solution of the present invention is that the sensing component includes a slider that slides inside a first housing, a limiting component for sliding the slider with a single degree of freedom on the first housing, the limiting component including limiting grooves on both sides of the first housing, limiting blocks that slide inside the limiting grooves on both sides of the slider, a hinge plate hinged to the slider, the hinge plate being connected to a slide rod, a sensor on one side of the slider, a first elastic element for slider reset on the first housing, and a movable cavity inside the first housing.

[0008] A further technical solution of the present invention is that a sliding cavity is provided inside the sliding rod, and the hinge plate can slide inside the sliding cavity.

[0009] A further technical solution of the present invention is that the wearable component includes a rotating shaft that rotates on a first housing and a second housing respectively, and a second elastic element for resetting the rotating shaft is provided on each rotating shaft. A strap is wound on the rotating shaft, and a buckle assembly is provided on the strap.

[0010] A further technical solution of the present invention is that the buckle assembly includes a male buckle and a female buckle respectively connected to two straps, and both the male buckle and the female buckle can be snapped together.

[0011] A further technical solution of the present invention is that the second housing is provided with a camera component via a connecting line.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 The present invention provides the following technical solution: a portable learning data acquisition device, comprising a first housing 1 and a second housing 2, the first housing 1 and the second housing 2 being arranged vertically and respectively wearable on the waist and chest of a student, and the first housing 1 and the second housing 2 being connected by a connector 4, and a camera component 5 being provided on the second housing 2, the camera component 5 being wearable on the student's head for recording video of the direction being faced.

[0029] The connector 4 has a telescopic function, which can be used to adjust the distance between the first shell 1 and the second shell 2 to accommodate students of different heights. It also makes it easy to adjust the first shell 1 and the second shell 2 to a comfortable position, reducing the discomfort of students wearing it. When the connector 4 is shortened, the first shell 1 and the second shell 2 can contact each other, so that the first shell 1 and the second shell 2 can be spliced ​​into a whole, making the collection easier to carry.

[0030] Please see Figure 2The connector 4 includes a slide rod 401 and a groove 402 is provided inside the second housing 2. The slide rod 401 can slide with a single degree of freedom inside the groove 402. The slide rod 401 is rectangular, and the groove 402 is a rectangle that matches the shape of the slide rod 401. This prevents the slide rod 401 from sliding inside the groove 402. When the slide rod 401 slides out of the groove 402, the telescopic function of the connector is realized.

[0031] Please continue reading. Figure 2 A sensing component 6 is provided inside the first housing 1. The connector 4 is connected to the sensing component 6. When the second housing 2 is displaced relative to the first housing 1, one end of the connector 4 can drive the sensing component 6 to be displaced, so that the sensing component 6 transmits the displacement signal of the connector 4 to the cloud platform 7. The cloud platform 7 collects and organizes the data. The sensing component 6 can be connected to the cloud platform 7 through a signal line (not shown in the figure). The signal line can extend along the connector 4 to the cloud platform 7.

[0032] like Figure 5 As shown, the sensing component 6 includes a slider 601 that slides horizontally inside the first housing 1. A limiting component 602 is provided on the first housing 1, which allows the slider 601 to slide only in a single degree of freedom direction inside the first housing 1. The limiting component 602 includes limiting grooves 603 provided on both sides of the first housing 1, and limiting blocks that slide inside the limiting grooves 602 are provided on both sides of the slider 601. The limiting blocks can limit the slider 601, allowing it to slide only in a single direction. A hinge plate 605 (e.g., hinged to the slider 601) is provided on the slider 601. Figure 2 As shown), a rotating hole is provided inside one end of the hinge plate 605, and a rotating shaft that rotates inside the rotating hole is integrally formed on the slider 601, so that the hinge plate 605 can rotate on the slider 601. The hinge plate 605 is connected to the slide rod 401. A sensor 604 is provided on one side of the slider 601. The sensor 604 is a pressure sensor. When the slide rod 401 pushes the slider 601 to move through the hinge plate 605, it can squeeze the sensor 604, so that the sensor 604 is subjected to force and generates a signal that is transmitted to the cloud platform. A first elastic element 606 is also provided on the first housing 1. The first elastic element is a compression spring. One end of the element abuts against the slider 601, and the other end abuts against the first housing 1. When the slider 601 moves and becomes weak, the first elastic element 606 can push the slider 601 to reset through its elasticity.

[0033] Please see Figure 2The first housing 1 has an internal movable cavity 8. The hinge plate 605, the slider 601 and the sensor 604 are all located inside the movable cavity 8. The movable cavity 8 has space for the hinge plate 605 to move, so that the hinge plate 605 can move the slider 601 inside the movable cavity 8.

[0034] The slide bar 401 has a sliding cavity 403 inside. The cross-section of the sliding cavity 403 can be rectangular, circular or other polygonal. This embodiment limits it. Of course, in order to make the hinge plate 605 slide more stably inside the sliding cavity 403, the cross-sectional shape of the hinge plate 605 can be adapted to the shape of the sliding cavity 403.

[0035] like Figure 1 As shown, both the first shell 1 and the second shell 2 are provided with wearable components 3, which can respectively put the first shell 1 and the second shell 2 onto the student's body;

[0036] Please see Figure 4 The wearable component 3 includes a rotating shaft 301 that rotates on the first housing 1 and the second housing 2 respectively. Each rotating shaft 301 is provided with a second elastic element 302, which is a coil spring. One end of the second elastic element 302 is fixed on the rotating shaft 301, and the other end is fixed on the first housing 1 or the second housing 2. Each of the first housing 1 and the second housing 2 is provided with an installation groove for installing the second elastic element 302. Two straps 303 are wound around the rotating shaft 301. Both the straps 303 and the rotating shaft 301 are provided on two sides of the first housing 1 and the second housing 2 respectively. The straps 303 are elastic straps that can improve the comfort when wearing. Each strap 303 is provided with a buckle assembly 304, which can connect the two straps 303 so that the first housing 1 and the second housing 2 can be tied to the student.

[0037] The buckle assembly 304 includes a male buckle 3041 and a female buckle 3042 respectively connected to two straps. The male buckle 3041 is provided with a post, and the female buckle 3042 is provided with a socket. The post can be inserted into the socket, thereby completing the snap-fit ​​of the buckle assembly 304.

[0038] like Figure 3As shown, the camera component 5 includes a first hoop 501 and a second hoop 502 that are hinged to each other. The first hoop 501 is connected to the cloud platform 7 via a connecting line 9. The connecting line 9 is spirally distributed, making it extendable. A camera 503 is mounted on the second hoop 502. An adjustment buckle 504 is mounted on the first hoop 501 and the second hoop 502. The adjustment buckle 504 can connect the ends of the first hoop 501 and the second hoop 502 that are close to each other, and can adjust the tightness of the first hoop 501 and the second hoop 502 when fixed on the head. A skin-friendly layer 505 is provided at the position where the first hoop 501 and the second hoop 502 contact the head. The skin-friendly layer 505 can directly contact the skin and has a certain degree of elasticity, which can improve the comfort when wearing it.

[0039] Please see Figure 3 and Figure 6 The adjusting buckle 504 includes inserts 5041 symmetrically arranged on the first clamp 501, with a third elastic member 5042 between the two inserts 5041. Each insert 5041 includes a plug portion 5043 and a pressing portion 5044. The plug portion 5043 has ratchet teeth. The second clamp 502 has a socket 5045, allowing the plug portion 5043 to be inserted into the socket 5045. A second ratchet tooth, matching the ratchet tooth, is located inside the socket 5045. The third elastic member 5042 can push the two inserts together. The ratchet teeth on the insertion part 5043 engage with each other, thereby allowing the adjusting buckle 504 to fasten and fix the first clamp 501 and the second clamp 502. When it is necessary to open, pinch the pressing part 5044 with your finger to bring the two insertion parts 5043 closer together. The ratchet teeth on the insertion part 5043 disengage from the second ratchet teeth inside the insertion hole 5045, thereby opening the adjusting buckle 504. By adjusting the depth of the insertion part 5043 inserted into the insertion hole 5045, the tightness of the first clamp 501 and the second clamp 502 can be adjusted.

[0040] Please see Figure 7 The second housing 2 is provided with heat dissipation holes, which can be used for heat dissipation of the cloud platform.
