Technical Field

[0001] This utility model belongs to the field of rehabilitation assistive equipment technology, and in particular relates to a rehabilitation assistive device. Background Technology

[0002] In the process of speech rehabilitation, patients need to train their speech. The tools commonly used in clinical practice for training include various speech function training cards. These cards usually contain a variety of test items, such as pronunciation, vocabulary comprehension, and sentence repetition, to comprehensively train the patient's speech ability.

[0003] When using training cards, which cover multiple dimensions (such as pronunciation, vocabulary, grammar, comprehension, etc.), each dimension requires multiple independent cards of varying sizes. As a result, the use of multiple cards of different sizes can easily lead to problems such as scattering and loss. Utility Model Content

[0004] The purpose of this invention is to provide a rehabilitation aid that minimizes the problem of assistive tools becoming scattered or lost.

[0005] The rehabilitation aid includes a box body with a support component at the bottom for supporting it upwards. A canvas is placed inside the box body, and pictures for speech rehabilitation training are printed on the canvas along its length. A drive component is placed inside the box body for moving the pictures on the canvas left and right. An observation hole is provided on the lid of the box body for observing the pictures on the canvas.

[0006] Furthermore, the driving component includes two rotating shafts, one on the left and one on the right. One end of the canvas is fixed to the left rotating shaft, and the other end is fixed to the right rotating shaft. One end of each rotating shaft is rotatably connected to the rear inner wall of the housing, and the other end of each shaft is connected to a servo motor for driving its rotation. The servo motor is installed on the front inner wall of the housing.

[0007] Furthermore, each of the rotating shafts is symmetrically fitted with two retaining rings for limiting the position of the canvas.

[0008] Furthermore, the rotating shaft is detachably connected between the housing and the servo motor.

[0009] Furthermore, the bottom of the canvas is provided with a support frame in the shape of an "arch bridge", which is fixed inside the box; the arched part of the support frame protrudes through the observation hole and is located above the box.

[0010] Furthermore, the bottom of the box cover on both sides of the observation hole is rotatably connected to a first guide roller for guiding the canvas.

[0011] Furthermore, a slide plate is provided below each of the first guide rollers, and a second guide roller is rotatably connected to the top of the slide plate; a groove is provided on the top of the support frame for the slide plate to slide up and down, and the slide plate and the groove slide up and down in a sliding fit; several springs are installed between the bottom of the groove and the slide plate, and in the natural state of the springs, the canvas is clamped between the first guide roller and the second guide roller.

[0012] Furthermore, the support assembly includes a support rod; the support rod is vertically arranged, with its upper end connected to the box body and its lower end fixed to a base plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a canvas with pictures for speech rehabilitation training printed along its length. The box contains a drive component for moving the pictures on the canvas left and right. Therefore, multiple sets of pictures for the rehabilitation training process can be printed sequentially on the canvas. By printing the required pictures uniformly on the canvas, the design avoids the problem of cards being scattered and lost, which is common in existing methods where the pictures for training are printed on multiple different cards.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0023] This embodiment describes an auxiliary chart for rehabilitation assessment, such as... Figure 1 and Figure 6 As shown, the device includes a box body 1, with a lid 6 on top. The lid 6 is detachable from the box body 1 and is locked to the box body 1 by latches. For example, latches can be provided on both the front and back sides of the box body 1 and the lid 6. The latches are existing known technology and include movable and fixed parts. The movable parts of the two sets of latches are fixed to the front and back side walls of the box body 1, and the fixed parts of the two sets of latches are fixed to the front and back side walls of the lid 6, respectively. The lid 6 can be closed and opened by the engagement and disengagement of the movable and fixed parts. Therefore, by opening the two sets of latches, the lid 6 can be easily removed from the box body 1.

[0024] like Figure 1 As shown, a support rod 8 is provided at the bottom of the box 1; the support rod 8 is vertically arranged, with its upper end connected to the box 1 and its lower end fixed to the base plate 9; this section of the design constitutes a support assembly for supporting the box 1 upwards; the base plate 9 is horizontally arranged, with the lower end of the support rod 8 fixed to the top of the base plate 9 and the upper end of the support rod 8 connected to the bottom of the box 1; therefore, through the design of the support rod 8 and the base plate 9, the box 1 can be supported upwards;

[0025] In implementation, the top of the support rod 8 in the support assembly can be hinged to the bottom of the housing 1 via the hinge rod 7. Specifically, the top of the hinge rod 7 is hinged to the bottom of the housing 1 via a damping pivot, and its bottom is hinged to the top of the support rod 8 via a damping pivot. After the hinge is completed, according to... Figure 1 The hinge rod 7 swings from front to back or from back to front. The damping shaft is a known existing product, a mechanical shaft that achieves slow and smooth rotation through a built-in damping structure. For example, laptop screens use damping shaft hinges. Therefore, the design of the damping shaft allows adjustment of the angle between the hinge rod 7 and the support rod 8, as well as the angle between the hinge rod 7 and the box 1. After adjustment, the stability between the box 1, the hinge rod 7, and the support rod 8 can be guaranteed under the action of the damping shaft. Therefore, the design of adjusting the angle of the box 1 makes it easier for the patient to observe the canvas 4 at the corresponding position on the box cover 6.

[0026] like Figure 1 and Figure 3As shown, a canvas 4 is provided inside the box 1, and the canvas 4 is printed with pictures for speech rehabilitation training along its length; according to Figure 3 The canvas 4 contains multiple printed sections 4.1 and spaced sections 4.2. Printed sections 4.1 are the parts containing the printed pictures, which consist of text and images. The text includes pronunciation, vocabulary, grammar, and comprehension. Printed sections 4.1 are separated by spaced sections 4.2, which are initially blank. Therefore, the design of spaced sections 4.2 facilitates the separation of different pictures. When a patient has a speech disorder and needs speech rehabilitation, they identify pictures in different positions on the canvas 4, such as pronunciation and sentence linking. The doctor then provides guidance based on the patient's responses to achieve the goal of speech rehabilitation training. When printing pictures on the canvas 4, multiple pictures are preferably printed sequentially according to the type and difficulty of the training. The patient can then identify the pictures on the canvas 4 sequentially from left to right or right to left, achieving gradual training. In this process, the design of printing the required pictures on the canvas 4 avoids the problem of easy scattering during storage caused by using multiple cards of different sizes in existing technologies.

[0027] like Figure 1 and Figure 3As shown, a rotating shaft 2 is provided inside the box body 1. There are two rotating shafts 2, one on the left and one on the right. One end of the canvas 4 is fixed to the left rotating shaft 2, and the other end is fixed to the right rotating shaft 2. One end of each rotating shaft 2 is rotatably connected to the rear inner side wall of the box body 1, and the other end of each is connected to a servo motor 14 for driving its rotation. The servo motor 14 is installed on the front inner side wall of the box body 1. This section of the solution constitutes a driving component for driving the picture on the canvas 4 to move left and right. The canvas 4 is placed horizontally, and the left end of the canvas 4 is wound around the left rotating shaft 2. The right end of the canvas 4 is wound around the right-side pivot 2; after the canvas 4 is wound, it passes over the top of the pivot 2; when one end of the pivot 2 is rotatably connected to the rear inner wall of the box 1, a blind hole is provided on the rear inner wall of the box 1, a bearing is installed in the blind hole, the outer ring of the bearing is fixed in the blind hole, and one end of the pivot 2 is fixed to the inner ring of the bearing; the servo motor 14 is electrically connected to a controller and a frequency converter, and the controller is electrically connected to a touch switch 15 and a battery; the battery is used to power the servo motor 14, and the touch switch 15 is used to control the servo motor 14. The start and stop of motor 14; the battery can be installed inside the housing 1, and the touch switch 15 can be installed on the top of the housing 6; the touch switch 15, through connection to the controller, can individually touch the left servo motor 14 to rotate forward or backward, individually touch the right servo motor 14 to rotate forward or backward, and touch both servo motors 14 to rotate forward simultaneously, and both servo motors 14 to rotate in reverse simultaneously; the above control methods are existing known methods, so they will not be described in detail; the power output end of the rotating shaft of the servo motor 14 is connected to the rotating shaft 2; therefore, the servo motor 14 can drive the rotating shaft 2 to rotate; when installing the canvas 4, if the difficulty level of the picture on the canvas 4 is from right to left, then the right side of the canvas 4 is the starting end, so the canvas 4 needs to be moved to the right; at this time, by turning on the touch switch 15 to control the rotation of the left servo motor 14, the left rotating shaft 2 can be driven to rotate, so the canvas 4 can be rolled up on the left rotating shaft 2. During the rolling process, when the canvas 4 is taut between the left and right rotating shafts 2, the left servo motor 14 is turned off; during use, according to Figure 1 The winding method of the canvas 4 is achieved by driving two servo motors 14 to rotate simultaneously (clockwise) via a touch switch 15, which moves the entire canvas 4 to the right. Because the servo motors 14 are electrically connected to a frequency converter, their speed can be adjusted to make the movement of the rotating shaft 2 and the canvas 4 more stable. Afterwards, medical staff observe the position of the pictures on the canvas 4. When the picture recognized by the patient is wound around the rotating shaft 2 on the right side, and the unrecognized picture moves to the right between the two rotating shafts 2, the two servo motors 14 are turned off. At this time, the canvas 4 stops moving. Therefore, the patient can train on the pictures in different positions on the canvas 4. Then, following the above method, the pictures on the canvas 4 are moved to the right in sequence, and the patient can train on the content of the pictures in sequence to achieve the purpose of gradual training.

[0028] In practice, the servo motor 14 in the drive assembly can be replaced with a brushless motor with a frequency converter;

[0029] like Figure 1 and Figure 4 As shown, the lid 6 of the box body 1 has an observation hole for observing the picture on the canvas 4; the observation hole is open from top to bottom; according to Figure 4 The preferred orientation of the observation hole is such that its length is greater than or equal to the distance between the two left and right intervals 4.2, its width is greater than the width of the canvas 4, and its location is between the two rotating shafts 2. The picture portion of the canvas 4 can then be observed through the position of the observation hole. Therefore, during use, the patient can identify the picture that has been moved to the position of the observation hole by observing its position.

[0030] like Figure 1 and Figure 3 As shown, two retaining rings 3 are symmetrically fitted on the rotating shaft 2 to limit the position of the canvas 4. After the canvas 4 is wound around the rotating shaft 2, according to... Figure 3 The canvas 4 is positioned such that its top contacts the retaining ring 3 at the top of the rotating shaft 2, and its bottom contacts the retaining ring 3 at the bottom of the rotating shaft 2. Therefore, the design of the retaining ring 3 can limit the position of the canvas 4, allowing the canvas 4 to be wound more stably on the rotating shaft 2.

[0031] like Figure 3 and Figure 5 As shown, the rotating shaft 2 is detachably connected between the housing 1 and the servo motor 14; specifically, when the detachable connection is implemented, a single rotating shaft 2 consists of three shafts, all located on the same straight line. The bottommost rotating shaft 2 is connected to the servo motor 14, and the canvas 4 is wrapped around the middle rotating shaft 2. The topmost rotating shaft 2 is rotatably connected to the housing 1. Both the top and bottom ends of the middle rotating shaft 2 have square protrusions (from... Figure 5 As can be seen from the orientation in the diagram, both the upper and lower rotating shafts 2 have slots for the protrusions to engage; the connection points of the three rotating shafts 2 are all provided with external threads, and threaded sleeves 16 are fitted at the positions of the external threads to engage with them; when the three rotating shafts 2 are installed together, the middle rotating shaft 2 is placed between the upper and lower rotating shafts 2, and then the protrusions at both ends of the middle rotating shaft 2 are engaged in the slots. By tightening the threaded sleeves 16 on the rotating shaft 2 at the protrusion engagement positions, the protrusions can be prevented from moving out of the slots, thus allowing the three rotating shafts 2 to be connected together; by unscrewing the threaded sleeves 16 from the protrusion positions, the protrusions can be moved out of the slots. Therefore, when the protrusions are moved out, the middle rotating shaft 2 can be removed from the box 1, thereby allowing the canvas 4 wrapped around it to be removed, achieving the purpose of detaching the canvas 4. Then, different canvases 4 with different printed content can be replaced according to adults and children;

[0032] like Figure 1 As shown, the bottom of the canvas 4 is equipped with an arch-shaped support frame 5, which is fixed inside the box 1. The arched part of the support frame 5 protrudes through the observation hole and is located above the box 1. The arch-shaped structure includes a "door"-shaped structure, with "I"-shaped structures fixed at both ends. The arched part of the support frame 5 is smaller than the length and width of the observation hole, so the arched part of the support frame 5 can protrude through the observation hole. The front sidewall of the support frame 5 is fixed to the front inner sidewall of the box 1, and the rear sidewall of the support frame 5... The side wall is fixed to the rear inner side wall of the box 1. In use, the bottom of the canvas 4 is laid on the top of the support frame 5, and then the ends of the canvas 4 are fixed to the two rotating shafts 2 respectively. Because the arched part of the support frame 5 is located above the box 1, when the canvas 4 is laid on the support frame 5, it can drive part of the canvas 4 to the top of the box 1. When part of the canvas 4 is pushed out of the box 1, the picture on the canvas 4 can be identified more clearly than by observing the canvas 4 inside the box 1 through the observation hole.

[0033] like Figure 1 and Figure 2 As shown, the bottom of the box cover 6 on both sides of the observation hole is rotatably connected to a first guide roller 10 for guiding the canvas 4. When the first guide roller 10 is rotatably connected, it is horizontally arranged and distributed front and back. Rotating rods and connecting blocks are provided on both the front and back sides of the first guide roller 10. The top of the connecting blocks is fixed to the bottom of the box cover 6. The first guide roller 10 is located between the two connecting blocks. Each connecting block has a through hole that connects the front and back. The rotating rod on the front side of the first guide roller 10 is installed in the through hole of the front connecting block through a bearing. The rotating rod on the rear side of the first guide roller 10 is installed in the through hole of the rear connecting block through a bearing. Therefore, the first guide roller 10 can rotate freely between the two connecting blocks. After the first guide roller 10 is installed, the bottom of the first guide roller 10 contacts the top of the canvas 4. Therefore, when the drive assembly moves the canvas 4 left and right, it can move along the first guide roller 10.

[0034] like Figure 1 and Figure 2As shown, a slide plate 12 is provided below each of the first guide rollers 10, and a second guide roller 11 is rotatably connected to the top of the slide plate 12; the top of the support frame 5 has a groove for the slide plate 12 to slide up and down, and the slide plate 12 and the groove slide in a vertical sliding fit; several springs 13 are installed between the bottom of the groove and the slide plate 12, and in the natural state of the springs 13, the canvas 4 is clamped between the first guide roller 10 and the second guide roller 11; the connection method of the second guide roller 11 is the same as that of the first guide roller 10, only the position is different, so it will not be described in detail; because the slide plate 12 can slide up and down in the groove, the slide plate 12 can drive the second guide roller 11 to move up and down when it moves up and down; when the spring 13 is installed, one end of the spring 13 is fixed to the bottom of the groove, and the other end is fixed to the bottom of the slide plate 12, so the spring 13 can push the second guide roller 11 to move upward; the second guide roller 11 is located at the bottom of the first guide roller. Directly below 10, the canvas 4 can be clamped between the first guide roller 10 and the second guide roller 11. In use, when the servo motor 14 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the canvas 4 to move left and right, the canvas 4 can overcome the elastic force of the spring 13 and move left and right between the second guide roller 11 and the first guide roller 10. When the servo motor 14 stops driving the rotating shaft 2 to rotate, the canvas 4 stops moving. When the canvas 4 stops moving, it can be clamped between the first guide roller 10 and the second guide roller 11. Because there are two sets of first guide rollers 10 and second guide rollers 11 on the left and right, when the drive component pulls the canvas 4 to move between the two sets of first guide rollers 10 and second guide rollers 11, the canvas 4 between the two sets of first guide rollers 10 and second guide rollers 11 can be laid more flat on the top of the support frame 5, and wrinkles in the picture at this position of the canvas 4 can be avoided as much as possible.

[0035] In practical use: First, adjust the tilt angle of the box 1 according to the patient's condition. Then, use the touch switch 15 to control the two servo motors 14 to rotate forward or backward simultaneously. This drives the two rotating shafts 2 to rotate at the same time. At this time, the canvas 4 on one rotating shaft 2 is rolled up, and the canvas 4 on the other rotating shaft 2 is unrolled. Therefore, the canvas 4 can move left or right on the top of the support frame 5, thereby moving the picture on the canvas 4 left or right. During speech rehabilitation training, the patient can recognize the picture in different positions on the canvas 4 by moving the canvas 4 left or right. Then, under the guidance of the doctor, the goal of rehabilitation training can be achieved. In this process, by printing different pictures in different positions on the canvas 4, the picture content on the rehabilitation training cards in the existing technology can be collected together, thus avoiding the problem of cards being easily scattered and lost due to the use of multiple rehabilitation training cards in the existing technology.
