DETAILED DESCRIPTION

[0030] In order to make the technical scheme of the embodiments of the present application or the prior art clearer, the accompanying drawings needed in the embodiments will be briefly introduced. Obviously, the accompanying drawings in the following description only need to explain some embodiments of the present application, and other drawings can be obtained by those skilled in the art based on these drawings.

[0031] Reference Figures 1-8The embodiment of the present application provides a mechanism with force feedback function for wearable sports equipment, which comprises a main body 1 arranged on a wearing structure and a sensor module, a force feedback module is arranged on the main body 1, the force feedback module comprises a vibration output mechanism operated based on an electric signal of the sensor module, the vibration output mechanism has a first vibration state and a second vibration state, and the amplitude of the first vibration state is smaller than that of the second vibration state.

[0032] Specifically, the wearable sports equipment is generally a glove, a watch or a vest, different equipment is selected for different sports, for example, a watch can be selected for running sports to record and process speed and time data; for VR simulation sports, a glove and a vest (and a VR glasses) can be selected to be used in cooperation to record and process limb movement, so that the effect of sports monitoring is achieved, which are all prior art and will not be described herein. The innovation point of the embodiment of the present application is that the main body 1 is arranged on the wearing structure (such as a vest), the sensor module (not shown) and the force feedback module are arranged on the main body 1, the sensor module is prior art, which can detect obstacles around the user, detect the movement rhythm or heart rate of the user; the force feedback module can select two groups of vibration structures in prior art, the two groups of vibration structures can vibrate with different amplitudes, so as to remind and feedback the user based on the sensor detection (the main body 1 is also provided with a control module, the sensor module and the force feedback module are electrically connected with the control module, after the control module receives the electric signal of the sensor module, the control module can send an electric signal to the force feedback module to control the operation of the force feedback module), for example, when obstacles are detected on the movement path, slight vibration can be used for reminding and feedback; when VR simulation sports are performed, strong vibration with large amplitude can be used to simulate the impact force; when the heart rate of the user is too high, the force feedback module can also warn the user; for the same situation, the amplitude becomes large (the impact force becomes large), which can also indicate that the situation becomes urgent (for example, the obstacle becomes close or the heart rate further increases, which can be indicated by vibration with large amplitude). The advantage of such arrangement is that in the process of monitoring the user's sports by using the wearing equipment, not only the physical condition of the user can be recorded and processed by the sensor and the like, but also the user can be fed back by the force feedback module to warn the user or simulate the impact force in the sports process, and different situations can be warned by the first state and the second state of the vibration output mechanism.

[0033] In the embodiment of the present application, the force feedback module can also be used in some scoring items, such as fighting sports, both sides wearing gloves and vest devices, the main body 1 can be arranged on the vest, and the sensor module in the main body 1 can record the number of hits (the sensor module can be arranged on the gloves and the vest to record the number of hits or the hitting force during the movement, and the force frequency and the force intensity are recorded by the sensor module and the control module, which is the prior art, and will not be described here), when the number of hits or the sum of the hitting force of one side reaches a certain threshold, the force feedback module can remind the user to lose points or fail (for example, the first state of the vibration output mechanism is to prompt the loss of points, and the second state is to prompt the failure); in the embodiment of the present application, the main body 1 can also be installed on the shoes, and in the training of kicking targets or kicking sandbags, the sensor module and the control module can record the number of kicks, so that the user can be reminded to reach the standard by the force feedback module when the number of kicks reaches a certain threshold.

[0034] In another embodiment of the present application, the vibration output mechanism includes a movable cavity 2 arranged on the main body 1, a shielding cloth 3 arranged in the movable cavity 2, a contact rod 4 slidably connected in the movable cavity 2, and a first elastic member 5 arranged between the main body 1 and the contact rod 4. Specifically, the movable cavity 2 is arranged with an opening on the side close to the user, and the edge of the shielding cloth 3 is fixed on the inner wall of the opening to block the movable cavity 2 through the shielding cloth 3, and at the same time, the shielding cloth 3 is used to contact the user, so that the contact rod 4 can contact the shielding cloth 3 when it operates to give force feedback to the user; a sliding groove is arranged on the inner wall of the movable cavity 2, and the contact rod 4 is slidably connected in the sliding groove; the first elastic member 5 can be a spring structure in the prior art, a connecting plate 6 is arranged on the contact rod 4, and the two ends of the first elastic member 5 are fixed on the inner wall of the movable cavity 2 and the connecting plate 6 respectively; the shielding plate has a certain elasticity, and in the normal state, the first elastic member 5 is not stressed, at this time, one end of the contact rod 4 contacts the shielding cloth 3, and the shielding cloth 3 basically does not deform; in this way, an eccentric wheel structure can be arranged in the movable cavity 2, and the contact rod 4 can be forced to reciprocate (i.e. vibrate) by the contact of the eccentric wheel and the first elastic member 5, so as to contact the shielding cloth 3 through the contact rod 4; two groups of contact rods 4 and eccentric wheel structures can be arranged in the movable cavity 2, so that the two contact rods 4 have two different amplitudes (i.e. the distance of reciprocating sliding of the contact rod 4 is different, because the contact rod 4 operates based on the elastic member, the distance of reciprocating sliding of the contact rod 4 changes slightly, which does not affect the user's feeling of force feedback), and the contact rod 4 with smaller amplitude can force the shielding cloth 3 to deform slightly to give the user slight force feedback, and the contact rod 4 with larger amplitude can force the shielding cloth 3 to deform greatly to give the user greater force feedback.

[0035] As an alternative to the two sets of abutting rods 4 and eccentric wheel structure in the above embodiments, a driving wheel 7 is rotatably connected in the movable cavity 2, and a protrusion 8 is formed on the driving wheel 7. The connecting plate 6 is located in the rotation stroke of the protrusion 8, and the driving wheel 7 has two rotation states of clockwise and counterclockwise rotation, so that the connecting plate 6 has a first stroke and a second stroke when it is abutted by the protrusion 8, and the displacement distance of the first stroke is smaller than that of the second stroke. Specifically, the main body 1 is provided with a driving source (such as a micro motor, which is a prior art and will not be described here, not shown) for driving the driving wheel 7 to rotate clockwise or counterclockwise; a plurality of protrusions 8 are provided on the driving wheel 7, and in the process of rotation of the driving wheel 7, the connecting plate 6 can be sequentially abutted by the plurality of protrusions 8 to cooperate with the first elastic member 5 to force the abutting rod 4 to move back and forth; when the first elastic member 5 is in a normal state, the connecting plate 6 is located on the side of the driving wheel 7 close to the shielding cloth 3. Obviously, when the driving wheel 7 rotates counterclockwise, the stroke of the connecting plate 6 forced to move is smaller than that when the driving wheel 7 rotates clockwise (as shown in FIG. 8). Figure 2

[0036] In this way, when the driving wheel 7 rotates clockwise, the protrusion 8 abuts the connecting plate 6 close to the shielding cloth 3, and in the process, the first elastic member 5 is stretched until the protrusion 8 is separated from the connecting plate 6, and then the connecting plate 6 is reset. When the driving wheel 7 rotates counterclockwise, the protrusion 8 abuts the connecting plate 6 away from the shielding cloth 3, and in the process, the first elastic member 5 is compressed until the protrusion 8 is separated from the connecting plate 6, and then the connecting plate 6 is reset. For clockwise and counterclockwise rotation of the driving wheel 7, the direction and displacement distance of the connecting plate 6 moving are different. When the protrusion 8 forces the connecting plate 6 and the abutting rod 4 to be close to the shielding cloth 3, the first elastic member 5 is stretched, and after the protrusion 8 is separated from the connecting plate 6, the abutting rod 4 is reset under the action of the first elastic member 5, which is the first state of the above vibration output mechanism. When the protrusion 8 forces the connecting plate 6 and the abutting rod 4 to be away from the shielding cloth 3, the first elastic member 5 is compressed, and at this time, the connecting plate 6 and the abutting rod 4 are first away from the shielding cloth 3, and then the protrusion 8 and the connecting plate 6 are separated, and the abutting rod 4 hits the shielding cloth 3 (i.e. hits the user's skin) under the elastic force of the first elastic member 5, thereby giving the user a more intense force feedback, which is the second state of the above vibration output mechanism. The advantage is that the clockwise and counterclockwise rotation of the driving wheel 7 can drive the connecting plate 6 to displace with different strokes, thereby driving the abutting rod 4 to vibrate with different strokes, and thereby abutting the shielding cloth 3 to different degrees to give the user different degrees of force feedback.

[0037] ​It should be noted that when the abutting rod 4 abuts against the shielding cloth 3 under the action of the first elastic member 5, the shielding cloth 3 cannot continue to deform due to the limitation of the user's skin, at this time, the moving stroke of the abutting rod 4 will be reduced, but the first elastic member 5 will generate a larger impact force to provide strong force feedback; that is, in the first state of the vibration output mechanism in this embodiment, the stroke (amplitude) of the reciprocating movement of the abutting rod 4 is smaller, and the abutting force of the abutting rod 4 on the user is smaller, and in the second state of the vibration output mechanism, the stroke (amplitude) of the reciprocating movement of the abutting rod 4 is larger, and the abutting force of the abutting rod 4 on the user is larger, thereby giving the user force feedback according to the actual situation.

[0038] In yet another embodiment of the present application, a connecting rod 9 is rotatably connected in the movable cavity 2, one end of the connecting rod 9 is provided with an arc-shaped block 10, and the arc-shaped block 10 abuts against the shielding cloth 3. A second elastic member for forcing the arc-shaped block 10 to abut against the shielding cloth 3 is arranged in the main body 1. The end of the connecting rod 9 away from the arc-shaped block 10 is provided with an abutting portion 11, and the abutting rod 4 is provided with an extending portion 12, the abutting portion 11 is located in the moving stroke of the extending portion 12, when the abutting rod 4 approaches the shielding cloth 3, the extending portion 12 abuts against the abutting portion 11 to force the arc-shaped block 10 away from the shielding cloth 3. Specifically, the second elastic member can be a torsional spring structure (not shown) in the prior art, which can force the connecting rod 9 to rotate to drive the arc-shaped block 10 to abut against the shielding cloth 3; the extending portion 12 is arranged on the outer wall of the abutting rod 4, when the first elastic member 5 is in a normal state, the abutting rod 4 and the arc-shaped block 10 both abut against the shielding cloth 3, at this time, there is still a certain gap between the extending portion 12 and the abutting portion 11, during the process of the abutting rod 4 approaching the shielding cloth 3 to give the user force feedback, the extending portion 12 abuts against the abutting portion 11 to force the connecting rod 9 to rotate against the elastic force of the second elastic member, thereby driving the arc-shaped block 10 away from the shielding cloth 3, until the abutting rod 4 is reset, the arc-shaped block 10 is reset under the elastic force of the second elastic member to abut against the shielding cloth 3 again, to provide the user with force feedback through the arc-shaped block 10; the advantage of such arrangement is that when the abutting rod 4 abuts against the shielding cloth 3, the extending portion 12 can passively drive the arc-shaped block 10 away from the shielding cloth 3, until the abutting rod 4 is reset under the action of the first elastic member 5, the abutting portion 11 loses the abutment of the extending portion 12, so that the connecting rod 9 can be reset under the action of the second elastic member, thereby driving the arc-shaped block 10 to abut against the shielding cloth 3, so that the force feedback given to the user by the overall device can be enriched, and the feedback effect is further improved.

[0039] Further, the inner wall of the movable cavity 2 is provided with a chute 13, the chute 13 is close to one end of the shielding cloth 3 and close to the abutting rod 4, the chute 13 is slidably connected with a sliding block 14, the sliding block 14 is hingedly connected with a linkage rod 15, the other end of the linkage rod 15 is hingedly connected with the connecting rod 9; the extension 12 is hingedly connected with a flap 16 on the side away from the shielding cloth 3, and the extension 12 is provided with a third elastic member to force the flap 16 to abut on the extension 12. Specifically, in the normal state, the abutting rod 4 and the arc-shaped block 10 abut on the shielding cloth 3, at this time, the sliding block 14 is located at one end of the chute 13 close to the shielding cloth 3, and the flap 16 and the extension 12 are located between the sliding block 14 and the abutting portion 11; when the protruding portion 8 forces the abutting rod 4 to be close to the shielding cloth 3, the extension 12 abuts on the abutting portion 11, so that the connecting rod 9 is passively rotated, and the sliding block 14 is adapted to slide in the chute 13 (in the process, the sliding block 14 and the flap 16 are not in contact); when the protruding portion 8 forces the abutting rod 4 to be away from the shielding cloth 3, the flap 16 abuts on the sliding block 14 (correspondingly, the flap 16 abuts on the extension 12), so as to drive the sliding block 14 to slide along the chute 13, thereby driving the arc-shaped block 10 and the abutting rod 4 to be away from the shielding cloth 3 together, since the chute 13 is inclined, the sliding block 14 gradually moves away from the abutting rod 4 in the process that the abutting rod 4 moves away from the flap 16, until the sliding block 14 and the flap 16 are separated, the connecting rod 9 is reset under the action of the second elastic member, so as to drive the sliding block 14 to be reset, and drive the arc-shaped block 10 to abut on the shielding cloth 3, thereby giving the user a gravity feedback; then the protruding portion 8 and the connecting plate 6 are separated, and the abutting rod 4 is also reset under the action of the first elastic member 5, thereby driving the abutting rod 4 to abut on the shielding cloth 3, to give the user a second gravity feedback, in the process, the flap 16 will abut on the sliding block 14, to force the flap 16 to overcome the elastic force of the third elastic member and avoid, until the flap 16 and the extension 12 move to the sliding block 14 and the abutting portion 11 again, the flap 16 abuts on the extension 12 again under the action of the third elastic member; in the process that the abutting rod 4 abuts on the shielding cloth 3, the abutting portion 11 is pressed, to drive the arc-shaped block 10 to be away from the shielding cloth 3 again, until the abutting rod 4 is reset, the arc-shaped block 10 is reset and abuts on the shielding cloth 3, thereby giving the user rich force feedback.

[0040] In the above embodiment, the force feedback mode is relatively monotonous, and if there is a gap between the shielding cloth 3 and the user, the change in the resistance degree brought by the amplitude change will be weakened, so that the user may not feel the change in the force feedback, and the user cannot distinguish the signal conveyed by the vibration output mechanism (cannot determine whether it is the signal corresponding to the first state or the signal corresponding to the second state). In the embodiment, the arc-shaped block 10 is added in the movable cavity 2, and when the driving wheel 7 drives the resistance rod 4 to operate, the resistance rod 4 can drive the arc-shaped block 10 to passively operate through the resistance part 11 and the sliding block 14 and the like, so as to give the user a rich force feedback feeling, and when the vibration output mechanism is in the first state and the second state, the user feels that the vibration amplitudes, frequencies and intensities of the resistance rod 4 and the arc-shaped block 10 are different, so that the user can perceive what kind of signal is output by the vibration output mechanism according to the vibration condition.

[0041] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of protection of the claims of the present application.
