Description

Technical Field

[0001] This invention relates to a method for detecting the body shape of a massage device, belonging to the technical field of massage devices. Background Technology

[0002] With the fast pace of life and increasing work pressure, massage has become an effective way to relax and relieve fatigue. Massage tools such as massage beds and chairs are popular due to their convenience and ability to relieve physical fatigue. Among the various parts of the body, the shoulders and lower back are particularly prone to fatigue and discomfort, making them key areas of focus during massage.

[0003] Currently, most massage devices on the market determine the massage area solely by detecting shoulder height. Specifically, these devices detect the user's shoulder height and then, based on the relatively fixed proportional relationships between parts of the body such as the hips, waist, and back, infer and determine the massage positions for other areas before performing the massage.

[0004] From a massage effectiveness perspective, while this method, based on shoulder height detection and conventional proportion calculation, can accurately locate the shoulder position to a certain extent, it suffers from limitations. Human body shapes vary; for example, the relative position between the waist and shoulders may differ among individuals of different body types and ages. This makes it difficult to precisely massage the user's desired lumbar region when determining the massage position using conventional proportions, failing to meet the need for precise waist massage and impacting both the massage effect and user experience.

[0005] Furthermore, for massage devices that use the head as a common starting point, such as massage beds, the user's head position is usually fixed after lying down. In this case, only the shoulder position is measured. However, height is an important factor affecting the relative positions of various body parts. Without height information, relying solely on shoulder position and conventional proportions makes it impossible to accurately locate the lumbar region. This makes it difficult for massage devices to provide personalized lumbar massage for users of different heights, limiting the applicability and practicality of massage devices.

[0006] Therefore, existing massage devices are significantly inadequate in terms of precise positioning of massage locations, especially the waist area. A body shape detection method for massage devices is needed to more accurately determine the massage location. Summary of the Invention

[0007] The purpose of this invention is to provide a body shape detection method for massage devices, thereby addressing the technical problems of insufficient body shape adaptability and precise massage positioning in existing massage devices. By combining the detection of shoulder and waist positions, this invention can adapt to different body shapes and user height differences, ensuring that the massage mechanism can accurately position itself at the two key massage points: the shoulders and waist.

[0008] The technical solution provided by this invention is as follows: A body shape detection method for a massage device, wherein the massage device includes a device body, the device body is provided with a massage plane, and a massage mechanism, a first drive motor, a second drive motor and a massage wheel are provided below the massage plane. The body shape detection method includes a shoulder position detection method and a waist position detection method. The waist position detection method is as follows: S1. Set the resistance stop threshold Fy of the second drive motor, set the preset total movement distance of the massage core from the shoulder to the buttocks as D, divide the preset total movement distance D into n equal distances, denoted as Li, where i=1,2,...,n; move the massage core to the shoulder position and retract the massage rollers below the massage plane; S2. The massage mechanism is driven by the first drive motor to travel a distance Li towards the buttocks and then stops. S3. The second drive motor drives the massage rollers to extend out of the massage surface and make contact with the human body; S4. If the resistance experienced by the second drive motor is greater than or equal to Fy, the second drive motor stops working, the cumulative number of rotations of the second drive motor Qi is recorded at this time, and the massage roller is controlled to retract below the massage plane; otherwise, continue to execute S3. S5. Calculate the position L of the massage mechanism to the shoulder at this time. If L≥D, where D is the preset total movement distance, then execute S6; otherwise, return to S2. S6. Compare the Qi values ​​of all records and mark the massage mechanism position corresponding to the maximum Qi value as the waist eye position.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the shoulder position detection method is as follows: P1. Set the resistance stop threshold Fx of the first drive motor, retract the massage rollers below the massage plane, and drive the massage mechanism to the head position through the first drive motor; P2. The massage rollers are driven out of the massage plane by the second drive motor; P3. The massage mechanism is driven by the first drive motor to move from the head to the buttocks. P4. If the resistance experienced by the first drive motor is greater than Fx, then stop the first drive motor and record the current position as the shoulder position; otherwise, continue executing P3.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, using the head position as the starting point of the massage, the shoulder position is detected starting from the head position. When the body is lying flat, the neck position is concave inward relative to the head and shoulder positions. At this time, the massage rollers are driven by the second drive motor to extend out of the massage plane and enter the concave neck area. Then, the massage mechanism is driven by the first drive motor to move from the head towards the buttocks, and the movement of the massage mechanism will move the massage rollers together. During the movement, when the massage rollers contact the shoulder, the resistance of the first drive motor will increase significantly. When the resistance of the first drive motor exceeds the preset threshold Fx, the first drive motor will stop working. At this point, the position of the massage mechanism is the user's shoulder position.

[0012] Furthermore, in step P4, after the first drive motor stops working, the cumulative number of rotations of the first drive motor when it moves from the head position to the buttocks position is recorded, the moving distance of the massage mechanism is calculated, and the distance from the head position to the shoulder position is obtained.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by recording the cumulative number of rotations of the first drive motor as it moves from the head position towards the buttocks, and converting this into the movement distance of the massage mechanism, the distance from the user's head to their shoulders can be obtained. This detection method can be personalized according to the user's actual body shape, ensuring the accuracy and comfort of the massage.

[0014] Furthermore, the massage rollers are rotatably mounted on the massage mechanism. The first drive motor is used to drive the massage mechanism to translate, and the second drive motor is used to drive the massage rollers to extend or retract into the massage plane by rotation.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated work of the first drive motor and the second drive motor, the translational movement of the massage mechanism is driven by the first drive motor, which can move linearly along the massage plane, while the extension and retraction of the massage rollers are achieved by the second drive motor through rotation, so that the massage rollers can flexibly contact the user's body and apply appropriate massage intensity as needed.

[0016] Furthermore, the massage device is equipped with a headrest at the top, allowing the user to lie flat on the massage device. When the user lies on the massage device, the headrest is positioned at the head position by default.

[0017] The advantage of adopting the above-mentioned further solution is that by setting the headrest position as the starting point for detecting the shoulder position, a fixed reference benchmark is provided for the entire body shape detection process. After the user lies flat on the massage bed with their head naturally placed on the headrest, the shoulder position detection can begin.

[0018] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The body shape detection method of the massage device of the present invention first detects the shoulder position, and then, starting from the shoulder position, gradually moves the massage core towards the buttocks, and uses the resistance change generated when the massage wheel contacts the human body to detect the waist position.

[0019] When detecting the shoulder position, the massage mechanism is moved by the first drive motor. When the massage rollers contact the shoulder, the resistance exerted by the shoulder on the massage rollers increases. The movement stops when the resistance of the first drive motor reaches a set threshold Fx. The position of the massage rollers at this point is the shoulder position.

[0020] When detecting the waist acupoint position, a resistance stop threshold Fy is set for the second drive motor. The massage mechanism stops after moving a preset distance Li towards the buttocks. Then, the massage roller extends out of the massage plane and contacts the body. After the massage roller contacts the body, the resistance on the second drive motor gradually increases as the massage roller penetrates further. When the resistance exceeds the set threshold Fy, the second drive motor stops working. At this time, the cumulative number of rotations of the second drive motor Qi is recorded. Since the human waist is usually concave inward, the second drive motor needs to rotate more times than other parts to ensure that the massage roller makes full contact with the waist acupoint position, especially at the highest point of the waist, where the corresponding cumulative number of rotations is also greater. By comparing the Qi recorded at different positions, the massage mechanism position corresponding to the maximum value of Qi is the waist acupoint position. Through the above-described method for detecting the shoulder and waist acupoint positions, this invention can accurately detect the user's shoulder and waist acupoint positions, providing a precise positioning basis for subsequent massage, thereby improving the targeting and comfort of the massage and meeting the personalized massage needs of different users.

[0021] The body shape detection method of this invention enables massage devices to adapt to different body shapes and user height differences, thereby more accurately locating the shoulder and waist areas. This not only improves the precision of the massage but also enhances the user experience, allowing the massage device to provide more personalized massage services for different users. Furthermore, this method is relatively simple to implement, requiring no complex external equipment or additional operating steps, making it highly practical and applicable.

Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0026] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 6As shown, a body shape detection method for a massage device is described. The massage device includes a body 1 with a massage plane 2. Below the massage plane 2 are a massage mechanism 3, a first drive motor 4, a second drive motor 5, and a massage wheel 6. The massage wheel 6 is rotatably mounted on the massage mechanism 3 via a connecting rod. The first drive motor 4 drives the massage mechanism 3 to move linearly along the massage plane 2. The second drive motor 5 drives the connecting rod to rotate. When the connecting rod rotates the massage wheel 6, the massage wheel 6 can extend or retract into the massage plane 2. When extended, the massage wheel 6 contacts the user's body and applies massage force. A headrest 7 is provided at the top of the massage device, allowing the user to lie flat on it. When the user lies on the massage device, the headrest 7 is the default head position. By setting the headrest 7 position as the starting point for detecting the shoulder position 8, a fixed reference benchmark is provided for the entire body shape detection process. After the user lies flat on the massage device, their head naturally rests on the headrest 7, and the detection of the shoulder position 8 can begin. Furthermore, when the user lies on the massage device, according to the curve of the human body, the neck and waist point 9 both indent away from the massage plane 2. The waist point refers to the deepest indentation in the waist area, which is an important acupoint during massage. The body shape detection method includes a shoulder position 8 detection method and a waist point 9 detection method. The shoulder position 8 detection method includes: P1. Set the resistance stop threshold Fx of the first drive motor 4, initialize the device, that is, retract the massage roller 6 under the massage plane 2, and drive the massage core 3 to move to the head position through the first drive motor 4; P2. The second drive motor 5 drives the massage roller 6 to extend out of the massage plane 2; P3. The massage mechanism 3 is driven by the first drive motor 4 to move at a constant speed from the head to the buttocks. P4. Monitor the resistance torque of the first drive motor 4 in real time. If the resistance of the first drive motor 4 is greater than Fx, it indicates that the massage roller 6 is in contact with the shoulder protrusion area. Then stop the first drive motor 4. The current position of the massage roller 6 is the shoulder position 8. Calculate the distance between the massage roller 6 and the head position to obtain the shoulder position 8; otherwise, continue to execute P3. In step P4, after the first drive motor 4 stops working, the cumulative number of rotations of the first drive motor 4 as it moves from the head position towards the buttocks is recorded. The movement distance of the massage mechanism 3 is then calculated, thus obtaining the distance from the head position to the shoulder position 8. By recording the cumulative number of rotations of the first drive motor 4 as it moves from the head position towards the buttocks and converting it into the movement distance of the massage mechanism 3, the distance from the user's head to the shoulder can be obtained. This detection method can be personalized according to the user's actual body shape, ensuring the accuracy and comfort of the massage.

[0028] The detection methods for the lumbar region include: S1. Set the resistance stop threshold Fy of the second drive motor 5, set the preset total movement distance from the shoulder to the buttock of the massage core to D, divide the preset total movement distance D into n equal distances, denoted as Li, where i=1,2,...,n; ensure that the massage core 3 is located at the shoulder position 8, and retract the massage roller 6 below the massage plane 2; S2. The first drive motor 4 drives the massage mechanism 3 to move a preset distance Li towards the buttocks and then stops to perform segment detection. The preset total movement distance D should be greater than or equal to the distance from the shoulder to the waist.

[0029] S3. After the massage mechanism 3 moves a distance Li and stops each time, the second drive motor 5 drives the massage roller 6 to extend out of the massage plane 2 so that it contacts the human body in order to detect the resistance. S4. Detect the resistance encountered by the second drive motor 5. If the resistance encountered by the second drive motor 5 is ≥ Fy, it means that the massage roller 6 has made contact with the human body and encountered significant resistance. At this time, stop the second drive motor 5 from working, record the cumulative value of the number of rotations of the second drive motor 5 Qi, and control the massage roller 6 to retract below the massage plane 2, preparing for the next distance test. If the resistance encountered by the second drive motor 5 is < Fy, continue to execute S3, that is, the second drive motor 5 continues to drive the massage roller 6 to extend out of the massage plane 2 to press the human body, and continue to detect the resistance. S5. Calculate the distance L from the massage mechanism 3 to the shoulder at this time. L = i·Li, which is the total distance that the massage mechanism 3 moves from the shoulder position 8 towards the buttocks. Compare the size of L and D. If L≥D, it means that a sufficiently long distance from the shoulder to the buttocks has been detected, then execute S6; otherwise, return to S2 and continue to detect the next distance until the condition L≥D is met.

[0030] S6. Compare all recorded Qi values. Since the waist eye position 9 is concave, the cumulative value of the number of rotations of the second drive motor 5 will be relatively large. Therefore, mark the position of the massage roller 6 corresponding to the maximum value Qi as the waist eye position 9. Calculate the horizontal distance from the massage roller 6 to the head at this time to determine the specific position of the user's waist on the massage plate plane.

[0031] In the embodiments of the present invention, during testing, firstly, the second drive motor 5 drives the massage roller 6 to extend out of the massage plane 2, and the massage roller 6 enters the concave neck area. Then, the first drive motor 4 drives the massage mechanism 3 to move from the head towards the buttocks, and the movement of the massage mechanism 3 will cause the massage roller 6 to move together. During the movement, when the massage roller 6 contacts the protruding part of the shoulder, the resistance experienced by the first drive motor 4 will increase significantly. When the resistance experienced by the first drive motor 4 exceeds a preset threshold Fx, the first drive motor 4 will stop working. At this time, the position of the massage mechanism 3 is the user's shoulder position 8.

[0032] In the embodiments of the present invention, during the detection process, the shoulder position 8 is detected first, and then the massage core 3 is gradually moved towards the buttocks starting from the shoulder position 8. The change in resistance generated when the massage roller 6 comes into contact with the human body is used to detect the waist position 9.

[0033] When detecting shoulder position 8, the head position is first used as the starting point for massage. Starting from the head position, the neck position is concave relative to the head position when the body is lying flat. The second drive motor 5 drives the massage roller 6 to extend out of the massage plane 2, and the massage roller 6 enters the concave neck area. Then, the first drive motor 4 drives the massage mechanism 3 to move from the head towards the buttocks. The movement of the massage mechanism 3 moves the massage roller 6 along with it. During the movement, when the massage roller 6 contacts the raised area of ​​the shoulder, the shoulder provides some resistance to the massage roller 6, increasing the resistance experienced by the first drive motor 4. When the resistance experienced by the first drive motor 4 exceeds a preset threshold Fx, the first drive motor 4 stops working, thus locating the user's shoulder position 8.

[0034] When detecting the waist-eye position 9, a resistance stop threshold Fy is set for the second drive motor 5. The massage mechanism 3 stops after moving a preset distance Li towards the buttocks. Then, the massage roller 6 extends out of the massage plane 2 and contacts the human body. After the massage roller 6 contacts the human body, as it penetrates further, the resistance experienced by the second drive motor 5 gradually increases. When the resistance exceeds the set threshold Fy, the second drive motor 5 stops working. At this time, the cumulative number of rotations of the second drive motor 5 is recorded as Qi. Since the human waist is usually concave inward, the second drive motor 5 needs to rotate more times than other parts to ensure that the massage roller 6 makes full contact with the waist-eye position 9, especially at the highest point of the waist, where the corresponding cumulative number of rotations is also greater. By comparing the Qi recorded at different positions, the position of the massage mechanism 3 corresponding to the maximum value of Qi is the waist-eye position 9. During the segmented scanning process, the concave area of ​​the waist requires a larger pressing stroke, i.e., a higher Qi value. By comparing the maximum value of Qi, the waist-eye position 9 can be accurately located.

[0035] By using the above-mentioned detection methods for shoulder position 8 and waist position 9, the present invention can accurately detect the user's shoulder position 8 and waist position 9, providing a precise positioning basis for subsequent massage, thereby improving the targeting and comfort of the massage and meeting the personalized massage needs of different users.

[0036] Using the body shape detection method described in this invention, the massage device can adapt to different body shapes and user height differences, thereby more accurately locating the shoulder position 8 and the waist position 9. This method not only improves the accuracy of the massage but also enhances the user experience, enabling the massage device to provide more personalized massage services for different users. Furthermore, the method is relatively simple to implement, requiring no complex external equipment or additional operating steps, and has high practicality and applicability.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
