Description

Massage device capable of achieving more accurate detection

Technical Field

Background

Currently, in the existing massage device, when the massage element of the massage movement acts on the human body, the human body exerts a reaction force on the massage head according to the subjective feeling of the human body. This affects the speed of movement of the massage elements. Therefore, it is necessary to accurately detect the movement position of the massage element. In order to more accurately control the motion state of the massage element when the massage device works, a motion detector is generally arranged on the massage machine core, the number of rotation turns and the rotation direction of the driving device are detected, and then the motion position of the massage element is calculated according to the motion state of the driving device.

The motion detector generally includes a detection device and a rotary disk, the rotary disk is mounted on a rotary shaft of the driving device, the detection circuit board is mounted on the fixed member, and the detection circuit board can receive a rotation signal when the rotary disk rotates. The control of the drive means is typically: first, the rotation speed and the rotation direction of the rotary shaft are detected by light-shielding and non-light-shielding of the rotary disk mounted on the driving device. Secondly, a magnetic ring (N and S poles respectively account for half) arranged on a shaft of the driving device is used for rotating and cutting a Hall sensor to detect the rotating speed and the steering of the rotating shaft; a single hall sensor can only measure rotational speed, at least two hall sensors are required to determine steering.

As described above, the conventional motion detector can generally determine only the rotation speed and the rotation direction, and cannot determine the rotation angle in real time. Since the opening of the existing rotating disk is a straight slot or a regular trapezoid (the change in voltage is of the staircase type) has no starting point. The existing magnetic ring has half of N pole and S pole, and the sensor can not find the starting point when the magnetic ring rotates.

Therefore, a massage device with more accurate detection is designed to solve the above problems.

The first embodiment is as follows: as shown in fig. 1, 2 and 5, a massage device capable of detecting more accurately comprises a massage element, a driving device, a motion detector and a control unit, wherein the motion detector is electrically connected with the control unit, the driving device comprises a transmission shaft for driving the massage element to move, the motion detector is used for detecting the position of the massage element to move, the motion detector comprises a detecting device 1 and a rotating disk 2, and the detecting device 1 is provided with a detecting hole 3; the rotating disc 2 and the transmission shaft are arranged in a synchronous rotating mode; the rotating disc 2 is provided with a plurality of shading areas 4 which are communicated along the circumferential rotation direction; when the rotating disk 2 rotates, the shading area 4 passes through and shades the detection hole 3, the detection device 1 detects the change of the voltage value, and the control unit judges the movement position of the massage element according to the change of the voltage value. The number of light-shielding regions 4 is six.

Example two: as shown in fig. 3 to 5, a massage device capable of detecting more accurately comprises a massage element, a driving device, a motion detector and a control unit, wherein the motion detector is electrically connected with the control unit, the driving device comprises a transmission shaft for driving the massage element to move, the motion detector is used for detecting the position of the massage element to move, the motion detector comprises a detecting device 1 and a rotating disk 2, and the detecting device 1 is provided with a detecting hole 3; the rotating disc 2 and the transmission shaft are arranged in a synchronous rotating mode; the rotating disc 2 is provided with a plurality of shading areas 4 which are communicated along the circumferential rotation direction; when the rotating disk 2 rotates, the shading area 4 passes through and shades the detection hole 3, the detection device 1 detects the change of the voltage value, and the control unit judges the movement position of the massage element according to the change of the voltage value. Each of the light shielding regions 4 includes a first light shielding portion 41, a second light shielding portion 42, and a third light shielding portion 43 arranged in this order in the circumferential rotation direction of the rotating disk 2. The first light shielding portions 41 of the respective light shielding regions 4 have different heights in the radial direction of the rotating disk 2. The second light-shielding portions 42 of the light-shielding regions 4 have the same structure, and the outer side of the second light-shielding portion 42 is an inclined surface. The height H of the detection hole 3 is H; when the rotating disk 2 rotates clockwise, the height H of the second shading part 42 shading the detection hole 3 increases from 0 to H, and the voltage value increases; when the rotary disk 2 rotates counterclockwise, the height H at which the second light-shielding portion 42 shields the detection hole 3 decreases from H to 0, and the voltage value decreases. The third light-shielding portions 43 of the light-shielding regions 4 have the same structure. The first light-shielding portion 41, the second light-shielding portion 42, and the third light-shielding portion 43 of the same light-shielding region 4 are provided so as to communicate with each other in the counterclockwise direction of the rotary disk 2. The number of light-shielding regions 4 is six.

The principle is as follows: as shown in fig. 3, the motion detector of the present apparatus is composed of two parts, a detecting device 1 and a rotating disk 2. As shown in FIG. 5, the detecting unit 1 has a detecting hole 3, and the height H of the detecting hole 3 is set to H. The voltage is set to be 0v when the detection hole 3 is not shielded, and the voltage is set to be 5v when the detection hole 3 is fully shielded. As shown in fig. 7, when the rotating disk 2 does not block the detection hole 3 of the detection device 1, the voltage at this time is V = 0V. As shown in fig. 8, when the rotating disk 2 partially shields the detection hole 3 on the detection device 1, the voltage at this time is 0V < 5V. As shown in fig. 9, when the rotary disk 2 completely blocks the detection hole 3 on the detection device 1, the voltage at this time is V = 5V. As shown in fig. 3 and 4, the rotating disk 2 can be divided into N equal parts, six equal parts in the figure, and each equal part is composed of three parts, namely, a first shading part 41, a second shading part 42 and a third shading part 43. As shown in FIG. 4, the heights of the first light-shielding portions 41 are different from one another, and when the different first light-shielding portions 41 shield the detection holes 3 of the detection device 1, fixed different voltage values are formed due to the different heights of the shields. As shown in fig. 10, voltages =0v, 1v, 2v, 3v, 4v, 5v are set for the first light shielding portion 41 in the six equal parts in the figure. When the rotating disk 2 rotates, the detecting device 1 detects a different voltage each time it reaches the first shading portion 41, and knows where the rotating disk 2 is located by the change of the voltage value, and presumes whether the rotating disk 2 rotates in the forward direction or the reverse direction by detecting the change of the voltage value. However, since the interval between each of the first light-shielding portions 41 is relatively large, the detection position accuracy is not high. As shown in fig. 4, the second light shielding portion 42 of the rotating disk 2 is composed of a slope; when the rotary disk 2 rotates clockwise, the height H of the detection hole 3 in the rotary disk 2 shielding detection device 1 gradually increases from 0 to H, and the corresponding detection voltage V also increases from 0V to 5V. Conversely, when the rotary disk 2 rotates counterclockwise, the height H of the detection hole 3 in the rotary disk 2 occlusion detection device 1 gradually decreases from H to 0, and the corresponding detection voltage V also decreases from 5V to 0V. Since the second light-shielding portion 42 continuously changes in value, the angle at which the rotary disk 2 rotates can be reversely estimated from the change in voltage even if the second light-shielding portion 42 is long. This solves the problem that the first light-shielding portion 41 cannot accurately measure the rotation angle, and also can determine the S.Anji turn according to the trend change of the voltage from low to high or from high to low. As shown in fig. 4, the voltage value of the third light-shielding portion 43 provided on the rotary disk 2 is always 5V, and the third light-shielding portion 43 functions to space the first light-shielding portion 41 and the second light-shielding portion 42. The rotating disk 2 is composed of three parts, a first shading part 41, a second shading part 42 and a third shading part 43, wherein the first shading part 41 corresponds to only one position of the rotating disk 2 on the whole circumference. When the rotating disk 2 rotates, each of the first shielding portions 41 is turned into a fixed voltage value, so that the program can know the rotating position of the rotating disk 2 in real time. When the rotating disk 2 rotates, the measured values change regularly as shown in fig. 11, where a, B, and C represent: the first light-shielding portion 41, the second light-shielding portion 42, and the third light-shielding portion 43.

The preferred embodiment is: the driving device is a motor or a rotating mechanism.

The utility model discloses on original detection rotational speed and the basis that turns to, the shape through changing the rotary disk has increased the function of the accurate angle of record, and the change of shape is not newly-increased cost, and the increase of record angle function can make the detection more accurate, has improved the real-time of control, has improved the market competition of product.
