Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention.

In one embodiment of the present invention, the load adjustment mechanism mainly comprises a driving part 2, an eccentric wheel 3, a motion sensor 4 and a motion controller 5.

Here, the driving member 2 is provided on the annular portion 1 of the wearable device, and is provided in the circumferential direction of the annular portion 1, generally in plural numbers at the same time. The driving unit 2 may be a driving motor.

The eccentric wheel 3 is also arranged on the annular part 1, is generally arranged in a plurality of numbers at the same time, is respectively connected with the output end of each corresponding driving component 2 and is mainly used for performing rotary motion under the power drive of the driving component 2.

The motion sensor 4 is disposed on the annular portion 1, and is mainly used for detecting the current motion state of the annular portion 1 so as to determine motion state parameters such as the motion direction and the motion speed of the annular portion 1.

The motion controller 5 is in signal connection with the motion sensor 4, and is mainly used for receiving detection data of the motion sensor 4, and when the body part of the user drives the annular part 1 to move, controlling each driving component 2 to drive each eccentric wheel 3 to rotate in an accelerated manner according to the current motion direction of the annular part 1 in the detection data, so that in the motion process of the body part of the user in the direction, the mass center of each eccentric wheel 3 rotates to face a target direction, and a certain included angle exists between the target direction and the current motion direction of the annular part 1.

Thus, the weight-bearing adjusting mechanism provided by the embodiment detects the motion state of the annular part 1 in real time through the motion sensor 4 when the user wears the wearable device to do exercise, namely detects the motion state of the part worn by the user, analyzes the current motion direction of the part worn by the user through the motion controller 5, and finally drives each eccentric wheel 3 to rotate in an accelerating manner to the direction of the mass center towards the target direction through each driving part 2. During this time, since the drive member 2 drives the respective eccentric 3 in an accelerated manner, the eccentric 3 is subjected to a rapidly increasing centripetal force (forming a rotational movement) which is mainly provided by the drive member 2, in this way, the eccentric 3 also exerts a rapidly increasing reaction force on the drive member 2 and on the annular portion 1 on which the drive member 2 is mounted, the direction of the reaction force is the target direction, and as the target direction has a certain included angle with the current movement direction of the wearing part of the user on the whole, when the two directions are integrally opposite, the counterforce generates a resistance effect on the wearing part of the user, when the two directions are integrally the same, the counterforce generates a thrust effect on the wearing part of the user, therefore, the anti-acceleration load mechanism that this embodiment provided can avoid volume, weight oversize to lead to the portability to worsen on the basis of realizing reasonable increase movement resistance, improves the user and wears the experience.

Generally, if the load effect (i.e. the resistance effect) on the wearing portion of the user needs to be increased, the target direction of the reaction force generally needs to be in a reverse state with respect to the current moving direction of the wearing portion of the user, i.e. the included angle between the target direction and the current moving direction of the ring portion 1 is in a range of (90 degrees, 180 degrees), otherwise, if the load effect (i.e. the thrust effect) on the wearing portion of the user needs to be decreased, the target direction generally needs to be in a same direction with the current moving direction of the wearing portion of the user, i.e. the included angle between the target direction and the current moving direction of the ring portion 1 is in a range of [0 degrees, 90 degrees ].

As shown in fig. 3, fig. 3 is a schematic view illustrating the control of the rotation direction of the eccentric wheel 3.

In a preferred embodiment of the motion controller 5, the motion controller 5 in this embodiment is embodied as a reverse accelerator in order to ensure as much as possible a sufficient motion resistance effect on the part of the user wearing it. Specifically, the reverse accelerator is mainly used for controlling each driving component 2 to drive the corresponding eccentric wheel 3 to accelerate and rotate until the direction of the mass center is opposite to the current movement direction of the annular part 1, namely, the direction of the mass center of the eccentric wheel 3 is opposite to the current movement direction of the wearing part of the user, or the direction of the mass center of the eccentric wheel 3 forms an included angle of 180 degrees with the current movement direction of the wearing part of the user. For example, when the user swings the arm with the wrist facing upward, the eccentric wheel 3 swings rapidly to the angle with the center of mass facing downward. Of course, the direction of the mass center of the eccentric wheel 3 and the current motion direction of the wearing part of the user can also be at other included angles, such as 135 degrees, and at this time, if the wrist of the user swings upwards currently, the eccentric wheel 3 swings rapidly to an angle that the mass center faces downwards left or downwards right.

Of course, the motion controller 5 may also be a forward accelerator, i.e. a device for controlling each driving member 2 to drive the corresponding eccentric 3 to rotate with the center of mass facing exactly the same direction as the current motion direction of the ring 1, e.g. if the user's wrist is swinging up, then the eccentric 3 swings rapidly to the angle with the center of mass facing up. So set up, can guarantee to wear the position to the user and form sufficient motion thrust effect as far as possible.

Further, in view of the fact that the user often needs to perform evacuation rest while performing exercise, the present embodiment adds an idle speed control module to the exercise controller 5. Specifically, the idle speed control module is in signal connection with the motion sensor 4, and when the motion sensor 4 detects that the current moving speed of the annular portion 1 is zero, each driving member 2 is controlled to drive the corresponding eccentric wheel 3 to be in an idle running state, such as low-speed uniform rotation. With the arrangement, when a user stops in a movement gap, each eccentric wheel 3 is in an idle running state, the reaction force of each eccentric wheel 3 distributed in the circumferential direction to the annular part 1 is basically counteracted mutually, and an obvious resistance effect is difficult to form to a wearing part, so that the wearing part of the user is temporarily relaxed and has a rest.

Furthermore, when considering that the user places after taking off the motion bracelet, if 3 idle running time overlengths of eccentric wheel then waste battery power easily, to this, this embodiment has add the control module that stops in motion controller 5. Specifically, the stop control module is also in signal connection with the motion sensor 4, and is mainly used for controlling the driving component 2 to stop running after detecting that the motion speed of the annular part 1 is zero and is kept for a preset time, such as 10-30 seconds, so that the eccentric wheel 3 stops idling, and the battery power is saved.

In a preferred embodiment of the eccentric 3, the plane of rotation of the respective eccentric 3 is in the radial plane of the annular part 1, in order to ensure that the reaction forces exerted by the eccentric 3 on the annular part 1 act as far as possible in the radial direction of the annular part 1. The arrangement is such that the axial direction of the respective eccentric 3 is perpendicular to the radial plane of the ring segment 1, and the reaction force exerted by the respective eccentric 3 on the ring segment 1 during the acceleration rotation and the drive force exerted by the user wearing part on the ring segment 1 are substantially in the radial plane of the ring segment 1.

Further, in order to improve the effect of the exercise resistance to the wearing part of the user, in the present embodiment, the eccentric wheels 3 are uniformly distributed along the outer circumferential surface of the ring part 1. And sealed by the housing. Generally, the eccentric wheels 3 can be simultaneously arranged in 8-16 numbers, the more the number is, the more obvious the formed motion resistance effect is, and the more balanced the motion resistance effect is.

Moreover, in order to further improve the effect of the motion resistance on the wearing part of the user, in this embodiment, a plurality of layers, such as 2 to 4 layers, are distributed on the outer circumferential surface of the annular part 1 along the thickness direction (or axial direction) of each eccentric wheel 3. So set up, each layer eccentric wheel 3 will be the level distribution to the motion resistance effect that the position formed is worn to the user to cover the certain width region that the position was worn to the user, can improve the motion resistance effect when, improve the user and wear the comfort level.

As described above, when the eccentrics 3 are arranged in layers on the outer circumferential surface of the ring portion 1, in order to facilitate the power output of the driving members 2 to the eccentrics 3, in the present embodiment, the driving members 2 are also arranged in layers on the outer circumferential surface of the ring portion 1, and the driving members 2 are arranged between two adjacent layers of the eccentrics 3. So set up, two eccentric wheels 3 can be connected simultaneously along axial both ends to single drive component 2, realize single-to-many output to improve the rotational motion synchronism of each eccentric wheel 3.

As shown in fig. 2, fig. 2 is a schematic view of an installation structure of the driving member 2 and the eccentric wheel 3.

In addition, in a preferred embodiment with respect to eccentric 3, eccentric 3 essentially comprises a connecting portion 31 and a weight 32. The connecting portion 31 is mainly used for connecting with the output end of the driving member 2, and is generally in a shaft shape or a column shape, for example, the connecting portion 31 can be connected with the output shaft of the driving motor, etc. so as to rotate under the power output of the driving member 2. The negative weight 32 is disposed on the outer circumferential surface of the connecting portion 31, is generally in the shape of an arc block or other shapes, has a relatively large mass, is significantly larger than the mass of the connecting portion 31, and is mainly used for radially outwardly offsetting the mass center of the eccentric wheel 3 so as to offset the mass center from the rotation axis by a certain distance. As shown in the figure, the weight block 32 shifts the mass center of the eccentric wheel 3 to a point p, the rotation center of the eccentric wheel 3 is a point o, and the direction from the point o to the point p is the orientation of the mass center of the eccentric wheel 3.
