The walking driving motor of the walking driving mechanism drives the massage machine core to move up and down relative to the machine frame, the walking position detecting mechanism detects the position of the massage machine core in the up and down direction and can cooperate with the control mechanism to control the massage machine core to move to the corresponding position of the machine frame, the information of the massage machine core in each position relative to the machine frame is stored in the control mechanism in the form of corresponding information numerical values, and the position information detected by the walking position detecting mechanism can be received and processed by the control mechanism in the form of corresponding information numerical values. The kneading driving mechanism drives the massage mechanism to move in the left-right direction (the width direction of the massage chair), the kneading driving mechanism has two design ideas, the first design ideas are that a kneading driving motor, a kneading shaft (also called a width driving shaft) and an eccentric hub are adopted to be matched, the massage mechanism is arranged on the eccentric hub, the kneading shaft drives the massage mechanism to reciprocate left and right through the eccentric hub, the other design ideas are that the kneading shaft is provided with external threads and the massage mechanism is provided with internal threads matched with the external threads, the kneading shaft controls the massage mechanism to move in the left-right direction through forward rotation or reverse rotation, and the massage mechanism can be provided with a width position detection mechanism for detecting the position of the massage mechanism in the left-right direction.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. Features of the embodiments described below may be combined with each other without conflict.
The massage chair comprises a frame and a massage machine core which can move up and down along the frame, and in combination with fig. 1, the massage machine core is provided with a massage mechanism, a walking driving motor, a walking position detection mechanism, a kneading driving motor, a strength position detection mechanism and a control mechanism, wherein the massage mechanism comprises a massage arm and a massage head arranged on the massage arm. The structure of the massage machine can be a massage chair in the prior art, and the specific structures of the frame and the massage machine core are not essential points of the application, so that the detailed description is omitted. The control mechanism can comprise a detection chip for detecting the current changes of the walking driving motor, the kneading driving motor and the strong and weak driving motor. The massage chair of the present application may also include a false alarm, the function of which will be described in further detail below.
The massage chair provided by the application has a first working state, wherein the first working state is a process that the massage machine core moves from top to bottom until the walking driving current value of the walking driving motor exceeds a walking current threshold value, and the control mechanism records a first walking position information value detected by the walking position detection mechanism when the walking driving current value exceeds the walking current threshold value. Before the massage machine enters the first working state, the walking driving motor drives the massage machine core to walk to the uppermost side of the frame, the strong and weak driving motor drives the massage mechanism to push forward to the forefront position, after the massage machine enters the first working state, the walking driving motor drives the massage machine core to walk downwards relative to the frame, when the massage mechanism does not contact the shoulder of a user, the current of the walking driving motor is no-load current, when the massage mechanism contacts the shoulder of the user, the current of the walking driving motor exceeds the no-load current, when the walking driving current value exceeds a walking current threshold value (the control mechanism is provided with a memory for storing the walking current threshold value and a comparator for comparing the walking current threshold value with the walking current threshold value), the control mechanism records a first walking position information value detected by the walking position detection mechanism, the massage head of the massage mechanism compacts the shoulder of the user at the moment, and the position corresponding to the first walking position information value is lower than the actual position of the shoulder. The walking current threshold is set after a plurality of experiments. In the first operating state, the kneading drive motor may be set to be inactive, so that the current when the walking drive motor contacts the user's shoulders can be detected relatively accurately.
The massage armchair is provided with a second working state, wherein the second working state is a process from bottom to top of the massage machine core until the kneading driving current value of the kneading driving motor exceeds a kneading current threshold, and the control mechanism records a second walking position information value detected by the walking position detection mechanism when the kneading driving current value of the kneading driving motor exceeds the kneading current threshold. Specifically, when the walking driving current value exceeds the walking current threshold (i.e. the first working state is finished), the walking driving motor continues to drive the massage machine core to move downwards for a preset distance (the preset distance may be 3cm to 8cm, for example, 5 cm), and then the massage chair enters the second working state, i.e. the massage machine core continues to move downwards for a preset distance after the first working state is finished, and then enters the second working state. After the second working state starts, the kneading driving motor drives the massage mechanism to conduct kneading massage and the walking driving motor drives the massage machine core to move upwards, when the massage mechanism does not contact the neck of a user, the massage mechanism can smoothly massage the back of the user, the kneading driving current of the kneading driving motor is stable and does not have excessive fluctuation, when the kneading mechanism kneads actively to clamp the neck of the user, the kneading driving current can be suddenly increased, when the control mechanism judges that the kneading driving current value of the kneading driving motor exceeds a kneading current threshold value, the control mechanism records a second walking position information value detected by the walking position detection mechanism, and the position corresponding to the second walking position information value is higher than the actual position of the shoulder. The kneading current threshold was set after multiple experiments.
After the control mechanism records the first walking position information value and the second walking position information value, it is further required to determine whether the actual deviation value of the first walking position information value and the second walking position information value is within the preset deviation value range. If the control mechanism judges that the actual deviation value is within the preset deviation value range, the control mechanism takes the intermediate walking position information value between the first walking position information value and the second walking position information value as the shoulder position information value, specifically, the shoulder position information value can be the sum of the first walking position information value and one-N-th of the actual deviation value, and N can be any natural number from 2 to 10, for example, N is 3. Fig. 2 shows the information of the shoulder position of different persons (A, B, C) detected by using the first walking position information value and the second walking position information value, it is noted that when the person a is tested, the difference between K2 and K1 is 31, and one third of the difference takes an integer value of 10. The preset deviation value range is set to be 50, if the control mechanism judges that the actual deviation value is not in the preset deviation value range, the control mechanism controls the massage armchair to reenter the first working state and the second working state, when the control mechanism controls the massage armchair to reenter the first working state and the second working state for M times, the control mechanism controls the error alarm to carry out error alarm when the acquired actual deviation value of the M groups of first walking position information values and the second walking position information values is out of the preset deviation value range, and M can be set to be 3 times.
The massage chair of the application also has a third working state, wherein the third working state is that the massage machine core intermittently moves from bottom to top or from top to bottom at intervals or intervals, and preferably the intervals can be the intervals. On the basis of detecting the shoulder position of the user, the third working state can be utilized to comprehensively detect back curve data of the user, and particularly, when the massage machine core intermittently moves at intervals or at intervals, the massage machine core stays on the machine frame for a while and moves relative to the machine frame for a while. The strong and weak driving motor can drive the massage mechanism to incline forward until the strong and weak driving current value of the strong and weak driving motor exceeds the strong and weak current threshold value when the massage machine core is in each stay position, and drive the massage mechanism to incline backward when the massage machine core is in an active process so that the strong and weak driving current value of the strong and weak driving motor is lower than the strong and weak current threshold value, and the control mechanism records the strong and weak position information value of the strong and weak position detection mechanism when the strong and weak driving current value of each stay position exceeds the strong and weak current threshold value. The intensity position information values correspond to the walking position information values of the corresponding stay positions one by one, when the massage mechanism is positioned at different positions of the frame, the massage mechanism can massage the forward tilting angle required by a user, the forward tilting position change condition of the massage mechanism reflects back body type information of the user, and the control mechanism controls the massage machine core to perform corresponding massage on each position of the back of the user by means of the back body type information.
The application further provides a body type detection method of the massage armchair, which comprises the steps S1, S2 and S3. Step S1: the control mechanism controls the massage armchair to be in a first working state and records the first walking position information value. Step S2: the control mechanism controls the massage armchair to be in a second working state and records the second walking position information value. Step S3: when the control mechanism judges that the actual deviation value of the first walking position information value and the second walking position information value is within the preset deviation value range, the control mechanism takes the middle walking position information value between the first walking position information value and the second walking position information value as the shoulder position information value; and when the control mechanism judges that the actual deviation value of the first walking position information value and the second walking position information value is not within the preset deviation value range, repeating the steps S1 and S2.
The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present application should be included in the present application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
