Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of massage instrument, concretely relates to a massage chair with double shoulder outside body width detection function. BACKGROUND

[0002] The structure of the conventional massage chair usually comprises a backrest frame, a massage core arranged on the backrest frame and capable of walking up and down along the backrest frame, and armrests arranged on both sides of the chair frame for the user to rest his arms.

[0003] Since the height and body shape of different user groups are different, the width between the two shoulders is also different, and the distance between the armrests of the conventional massage chair is fixed, which causes the user's two arms to rest on the armrests to easily produce an uncomfortable feeling, and also affects the massage effect of the massage mechanism arranged on the armrests, making it difficult to effectively massage the user's arms, shoulder sides and other parts.

[0004] When the conventional massage chair implements targeted massage of the scapular part (including the deltoid muscle, trapezius muscle and other parts) of the user's back, it is achieved by controlling the massage core to move to a specific position for massage, and this moving position is usually fixed and cannot be adjusted according to the height and body shape of the user. Some massage chairs also allow the user to adjust the position of the massage core according to his needs when in use, which is inconvenient to use.

[0005] A flexible fabric sensor (also known as a sensing cloth) is a smart textile integrated with sensing materials or elements, which can convert external stimuli such as pressure and tension into electrical signals, and has soft, body-fitting wearing performance and flexible structure. This sensor is mainly prepared by coating, weaving or encapsulation, and is widely used in medical health monitoring, sports detection and intelligent protection fields. Due to its excellent flexibility and wearability, it also has great potential in the application field of massage instruments. UTILITY MODEL CONTENTS

[0019] The structure of the massage chair with the double-shoulder outer side body width detection function according to the embodiment of the utility model is shown in the figure Figures 1-5 As shown in the figure, the front side of the backrest frame 1 is covered with a backrest pad, the armrest 2 and the backrest frame 1 form a movable connection cooperation that enables the two armrests 2 to move towards the direction of approaching and moving away from each other, the backrest frame 1 is provided with a driving mechanism for driving the movement of the two armrests 2, the armrest 2 is provided with a sensing cloth 21 for sensing the position of the shoulder, the sensing cloth 21 generates an electric signal when it is pressed, the sensing cloth 21 and the driving mechanism are linked and cooperated, the linkage cooperation refers to the use of the electric signal generated by the sensing cloth 21 to determine the position of the armrest, the sensing cloth has a pressure sensing threshold interval, through the conventional control program design, the armrest can be driven to move to the position close to the user's shoulder by the driving mechanism, the judgment can be made according to whether the pressure value sensed by the sensing cloth exceeds the preset threshold interval, when the pressure value when the sensing cloth contacts the shoulder is greater than the set maximum threshold value, the armrest is controlled to move away from the shoulder, when it is less than the set minimum threshold value, the armrest is controlled to move close to the shoulder, the armrest is always kept close to the two sides of the shoulder, the automatic shoulder-close function is realized, and when the pressure value is within the threshold range interval, the driving mechanism is controlled to stop working.

[0020] As shown in the figure Figure 4 The bottom of the backrest frame 1 is provided with a guide rail 31, the two ends of the guide rail 31 are provided corresponding to the two side directions of the backrest frame 1, the lower end of the armrest 2 is provided with a sliding support 22 that forms a sliding cooperation with the guide rail 31, and the sliding support 22 is provided with a sliding block 32 that cooperates with the guide rail 31 to slide. The sliding block 32 and the guide rail 31 are correspondingly provided in two groups, the two groups of guide rails 31 are arranged in parallel, which can improve the stability of the sliding support 22 when it moves. In order to further improve the stability of the armrest as a whole, the lower end of the sliding support 22 is further provided with a roller 4.

[0021] As shown in the figure Figure 3 The driving mechanism comprises a servo motor 51 and a transmission rod 52, the output shaft of the servo motor 51 and the transmission rod 52 are at a position perpendicular to each other, the output shaft of the servo motor 51 and the middle part of the transmission rod 52 are transmission-connected through a worm gear 53 and a worm 54, the two ends of the transmission rod 52 are provided with opposite threads 521, the sliding support 22 is provided with a movable block 55 that cooperates with the threads of the transmission rod 52, and the movable blocks 55 of the sliding supports 22 of the two armrests 2 are correspondingly connected and cooperated with the threads 521 at the two ends of the transmission rod 52.

[0022] When the servo motor 51 drives the transmission rod 52 to rotate in two directions respectively, through the movable cooperation between the transmission rod 52 and the movable block 55, the two armrests can be driven to move towards the direction of approaching or moving away.

[0023] The sensing cloth 21 is arranged at a position corresponding to the shoulder on the inner side of the armrest, as shown in Figure 1 , 5 The accuracy of the adaptive adjustment of the position of the armrest 2 can be improved.

[0024] As shown in Figure 5 , the armrest 2 is provided with a massage mechanism 6 capable of massaging the shoulder, the massage mechanism 6 is arranged on the inner side of the sensing cloth 21 and is linked with the sensing cloth 21, in order to avoid the sensing cloth 21 being rubbed and damaged under the action of the massage mechanism 6, a wear-resistant cloth 23 is further arranged on the inner side of the sensing cloth 21. When the massage mechanism 6 works, massage can be applied to the outer side of the user's shoulder through the sensing cloth 21 and the wear-resistant cloth 23, the structure is more compact, and the massage effect on the outer side of the shoulder can be improved.

[0025] In addition, since the sensing cloth 21 can sense the pressure distribution of different areas of the shoulder in real time, more targeted massage can be performed on the shoulder area of the user through the linkage with the massage mechanism 6, for example, the massage mechanism 6 can autonomously adjust the massage strength and massage method according to the pressure condition, in cooperation with the recognition of the acupoint position of the shoulder, it is helpful to make the massage chair more accurately position and massage the key acupoints of the user's back, improve the massage effect, and achieve the purpose of traditional Chinese medicine physiotherapy and recuperation.

[0026] The above embodiments are only one of the preferred specific embodiments of the present application, and the usual changes and replacements made by those skilled in the art within the scope of the technical scheme of the present application are all included in the protection scope of the present application.
