Description

Technical Field

[0001] This invention relates to the field of smart terminal technology, and more specifically to a mechanism for wearable sports devices with force feedback function. Background Technology

[0002] With the development of technology, many wearable devices have emerged. Wearable devices can detect users' movement data in real time and analyze the user's current status based on the movement data.

[0003] For example, the patent document with authorization announcement number CN220820539U, authorization announcement date of April 19, 2024, and titled "An Adjustable Smart Wearable Device," includes a housing, a control circuit board disposed inside the housing, a functional module disposed on the housing, and a charging module. The charging module and the functional module are all electrically connected to the control circuit board, and the charging module is detachably connected to the housing. This type of wearable device has high adaptability.

[0004] In existing technologies, wearable sports devices can generally only record and process sports data, but cannot provide users with force feedback in real time based on the sports situation. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanism for wearable sports devices with force feedback function to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mechanism for a wearable sports device with force feedback function includes a main body and a sensor module disposed on a wearable structure, wherein the main body is provided with:

[0008] The force feedback module includes a vibration output mechanism that operates based on the electrical signal of the sensor module. The vibration output mechanism has a first vibration state and a second vibration state, wherein the amplitude of the first vibration state is smaller than the amplitude of the second vibration state.

[0009] The above-mentioned mechanism for a wearable sports device with force feedback function includes a vibration output mechanism comprising a movable cavity constructed on the main body, a shielding cloth disposed in the movable cavity, an abutment rod slidably connected in the movable cavity, and a first elastic element disposed between the main body and the abutment rod.

[0010] In the aforementioned mechanism for a wearable sports device with force feedback function, a connecting plate is constructed on the abutment rod, and the two ends of the first elastic element are respectively fixed to the inner wall of the movable cavity and the connecting plate.

[0011] In the above-mentioned mechanism for a wearable sports device with force feedback function, a drive wheel is rotatably connected inside the active cavity, and a protrusion is constructed on the drive wheel.

[0012] In the above-mentioned mechanism for a wearable sports device with force feedback function, the connecting plate is located on the rotational stroke of the protrusion, and the drive wheel has two rotational states, so that when the connecting plate is abutted by the protrusion, it has a first stroke and a second stroke, and the displacement distance of the first stroke is less than the displacement distance of the second stroke.

[0013] In the above-mentioned mechanism for a wearable sports device with force feedback function, when the drive wheel rotates forward, the protrusion abuts against the connecting plate and approaches the shielding cloth. During this process, the first elastic element is stretched until the protrusion separates from the connecting plate, and then the connecting plate resets.

[0014] In the above-mentioned mechanism for a wearable sports device with force feedback function, when the drive wheel reverses, the protrusion abuts against the connecting plate and moves away from the cover cloth. During this process, the first elastic element is squeezed until the protrusion separates from the connecting plate, and then the connecting plate resets.

[0015] In the aforementioned mechanism for a wearable sports device with force feedback function, a connecting rod is rotatably connected within the active cavity, and one end of the connecting rod is constructed with an arc-shaped block, which abuts against the shielding cloth.

[0016] The aforementioned mechanism for a wearable sports device with force feedback function includes a second elastic element within the main body for forcing the arc-shaped block to collide with the cover cloth.

[0017] In the above-mentioned mechanism for a wearable sports device with force feedback function, the end of the connecting rod away from the arc-shaped block is provided with an abutment, and an extension is provided on the abutment rod. The abutment is located on the travel of the extension. When the abutment rod approaches the cover cloth, the extension abuts the abutment to force the arc-shaped block away from the cover cloth.

[0018] In the above technical solution, the present invention provides a mechanism for wearable sports devices with force feedback function. By setting a force feedback module, it can work in conjunction with a sensor module to drive a vibration output mechanism to operate at an appropriate time. The vibration output mechanism has two states with different amplitudes to provide appropriate force feedback when appropriate. For example, the first vibration state can provide slight vibration feedback, and the second vibration state can provide a certain impact force feedback, so as to provide appropriate feedback to the user through the wearable sports device.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1-8This invention provides a mechanism for a wearable sports device with force feedback function, including a main body 1 and a sensor module disposed on a wearable structure. The main body 1 is provided with a force feedback module, which includes a vibration output mechanism that operates based on the electrical signal of the sensor module. The vibration output mechanism has a first vibration state and a second vibration state, wherein the amplitude of the first vibration state is smaller than the amplitude of the second vibration state.

[0032] Specifically, wearable sports equipment generally includes gloves, watches, or vests. Different devices are selected for different sports. For example, watches can be used to record and process data such as speed and time when running. For VR simulation sports, gloves and vests (as well as VR glasses) can be used together to record and process limb movements, thereby achieving the effect of sports monitoring. All of the above are existing technologies and will not be elaborated here. The innovation of this invention lies in the fact that the main body 1 is mounted on a wearable structure (such as a vest), and a sensor module (not shown) and a force feedback module are mounted on the main body 1. The sensor module is a prior art technology and can detect obstacles around the user, as well as the user's own movement rhythm or heart rate. The force feedback module can use two sets of vibration structures from the prior art, which can vibrate with different amplitudes to remind and provide feedback to the user based on the sensor detection. (The main body 1 is also equipped with a control module, and both the sensor module and the force feedback module are electrically connected to the control module. After receiving the electrical signal from the sensor module, the control module can send an electrical signal to the force feedback module to control its operation.) For example, if an obstacle is detected in the movement path, a slight vibration can be used to remind and provide feedback. When performing VR simulated exercise, a strong vibration with a larger amplitude can simulate the impact force. If the user's heart rate is detected to be too high, the force feedback module can also warn the user. For the same situation, a larger amplitude (a larger impact force) can also indicate that the situation has become urgent (e.g., an approaching obstacle or a further increase in heart rate can be indicated by a larger amplitude vibration). The advantage of this setup is that, during the process of monitoring a user's movement using wearable devices, not only can the user's physical condition be recorded and processed through sensors and other structures, but also feedback can be provided to the user through a force feedback module to warn the user or simulate the impact force experienced during exercise. Furthermore, the first and second states of the vibration output mechanism can warn of different situations.

[0033] In this embodiment of the invention, the force feedback module can also be used in some scoring projects, such as combat sports, where both parties wear gloves and vests. The main body 1 can be set on the vest, and the sensor module in the main body 1 can record the number of times it is hit (sensor modules can be set on both gloves and vests to record the number of hits or the force of the hits during the movement. Recording the number of force hits and the force intensity through the sensor module and the control module is existing technology and will not be elaborated here). When the total number of hits or the total force of the hits reaches a certain threshold, the force feedback module can remind the user of lost points or failure (e.g., the first state of the vibration output mechanism is to remind the user of lost points, and the second state is to remind the user of failure). In this embodiment of the invention, the main body 1 can also be installed on shoes. In target kicking or sandbag kicking training, the sensor module and the control module can record the number of times the target is kicked, so that when the number of times the target is kicked reaches a certain threshold, the force feedback module can remind the user of the achievement.

[0034] In another embodiment of the present invention, the vibration output mechanism includes a movable cavity 2 constructed on a main body 1. A shielding cloth 3 is disposed inside the movable cavity 2, and an abutment rod 4 is slidably connected inside the movable cavity 2. A first elastic element 5 is disposed between the main body 1 and the abutment rod 4. Specifically, the movable cavity 2 has an opening on the side closest to the user. The edge of the shielding cloth 3 is fixed to the inner wall of the opening to seal the movable cavity 2. At the same time, the shielding cloth 3 is used to contact the user, so that the abutment rod 4 can abut against the shielding cloth 3 during operation to provide force feedback to the user. A groove is constructed on the inner wall of the movable cavity 2, and the abutment rod 4 is slidably connected in the groove. The first elastic element 5 can be a spring structure in the prior art. A connecting plate 6 is constructed on the abutment rod 4, and the two ends of the first elastic element 5 are respectively fixed to the inner wall of the movable cavity 2 and the connecting plate 6. The shielding plate has a certain elasticity. Under normal conditions, the first elastic element 5 is not under force. At this time, one end of the abutment rod 4 abuts against the shielding cloth 3, and the shielding cloth 3 basically does not deform. With this configuration, An eccentric wheel structure is installed in the active cavity 2. The eccentric wheel and the first elastic element 5 can force the abutment rod 4 to slide back and forth (i.e., vibrate), thereby abutting the shielding cloth 3. Two sets of abutment rods 4 and eccentric wheel structures can be installed in the active cavity 2, so that the two abutment rods 4 have two different amplitudes (i.e., the distance of the abutment rod 4 sliding back and forth is different. Since the abutment rod 4 is based on the elastic element, the distance of the abutment rod 4 sliding back and forth changes slightly, which does not affect the user's feeling of force feedback). The abutment rod 4 with a smaller amplitude can force the shielding cloth 3 to deform slightly to give the user a slight force feedback, while the abutment rod 4 with a larger amplitude can force the shielding cloth 3 to deform more significantly to give the user a greater force feedback.

[0035] As an alternative to the two sets of abutment rods 4 and eccentric wheel structure in the above embodiment, a drive wheel 7 is rotatably connected inside the movable cavity 2, and a protrusion 8 is constructed on the drive wheel 7. The connecting plate 6 is located on the rotational stroke of the protrusion 8, and the drive wheel 7 has two rotational states, so that when the connecting plate 6 is abutted by the protrusion 8, it has a first stroke and a second stroke, and the displacement distance of the first stroke is less than the displacement distance of the second stroke. Specifically, the main body 1 is equipped with a drive source (such as a micro motor, which is existing technology and will not be described in detail here, nor is it shown in the figure) for driving the drive wheel 7 to rotate forward or backward; the drive wheel 7 is equipped with multiple protrusions 8, which can sequentially abut against the connecting plate 6 during the rotation of the drive wheel 7, so as to cooperate with the first elastic member 5 to force the abutment rod 4 to move back and forth; when the first elastic member 5 is in the normal state, the connecting plate 6 is located on the side of the drive wheel 7 closer to the shielding cloth 3. Obviously, the stroke that forces the connecting plate 6 to move when the drive wheel 7 rotates counterclockwise is less than the stroke that forces the connecting plate 6 to move when the drive wheel 7 rotates clockwise (such as a micro motor, which is existing technology and will not be described in the figure). Figure 2 (As shown).

[0036] With this configuration, when the drive wheel 7 rotates forward, the protrusion 8 contacts the connecting plate 6 near the shielding cloth 3. During this process, the first elastic element 5 is stretched until the protrusion 8 separates from the connecting plate 6, at which point the connecting plate 6 returns to its original position. When the drive wheel 7 rotates in the reverse direction, the protrusion 8 contacts the connecting plate 6 away from the shielding cloth 3. During this process, the first elastic element 5 is compressed until the protrusion 8 separates from the connecting plate 6, at which point the connecting plate 6 returns to its original position. For the drive wheel 7 to rotate forward and backward, the direction and displacement distance of the connecting plate 6 are different. When the protrusion 8 forces the connecting plate 6 and the abutment rod 4 closer to the cover cloth 3, the first elastic element 5 is stretched until the protrusion 8 separates from the connecting plate 6. Then, the abutment rod 4 returns to its original position under the action of the first elastic element 5. This is the first state of the vibration output mechanism. When the protrusion 8 forces the connecting plate 6 and the abutment rod 4 away from the cover cloth 3, the first elastic element 5 is compressed. At this time, the connecting plate 6 and the abutment rod 4 first move away from the cover cloth 3, and then the protrusion 8 separates from the connecting plate 6. Under the elastic force of the first elastic element 5, the abutment rod 4 strikes the cover cloth 3 (that is, strikes the user's skin), thus giving the user a stronger force feedback. This is the second state of the vibration output mechanism. The advantage is that the forward and reverse rotation of the drive wheel 7 can drive the connecting plate 6 to move at different strokes, thereby driving the abutment rod 4 to vibrate at different strokes, thus providing different degrees of abutment to the cover cloth 3, and thus giving the user different degrees of force feedback.

[0037] It should be noted that when the abutment rod 4 abuts against the shielding cloth 3 under the action of the first elastic member 5, the shielding cloth 3 will be restricted by the user's skin and will not be able to continue to deform. At this time, the travel of the abutment rod 4 will decrease, but the first elastic member 5 will generate a large impact force, thereby providing strong force feedback. That is, in the first state of the vibration output mechanism in this embodiment, the travel (amplitude) of the abutment rod 4 is small and the abutment rod 4 has a small resistance force against the user. In the second state of the vibration output mechanism, the travel (amplitude) of the abutment rod 4 is large and the abutment rod 4 has a large resistance force against the user, thereby providing force feedback to the user based on the actual situation.

[0038] In another embodiment of the present invention, a connecting rod 9 is rotatably connected within the movable cavity 2. One end of the connecting rod 9 has an arc-shaped block 10, which abuts against the shielding cloth 3. A second elastic member is provided within the main body 1 to force the arc-shaped block 10 against the shielding cloth 3. The end of the connecting rod 9 away from the arc-shaped block 10 has an abutting portion 11. An extension portion 12 is provided on the abutting rod 4. The abutting portion 11 is located on the travel of the extension portion 12. When the abutting rod 4 approaches the shielding cloth 3, the extension 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 element can be a torsion spring structure (not shown) from the prior art, which can force the connecting rod 9 to rotate so that the arc-shaped block 10 abuts against the shielding cloth 3; the extension 12 is constructed on the outer wall of the abutting rod 4. When the first elastic element 5 is in its normal state, both the abutting rod 4 and the arc-shaped block 10 abut against the shielding cloth 3. At this time, there is still a certain gap between the extension 12 and the abutting part 11. During the process of the abutting rod 4 approaching the shielding cloth 3 to provide force feedback to the user, the extension 12 abuts against the abutting part 11 to force the connecting rod 9 to overcome the elastic force of the second elastic element and rotate, thereby driving the arc-shaped block 10 away from the shielding cloth 3 until it abuts against the shielding cloth 3. After the contact rod 4 resets, the arc-shaped block 10 resets under the elastic force of the second elastic element to abut against the shielding cloth 3 again, so as to provide force feedback to the user through the arc-shaped block 10. The advantage of this setting is that when the contact rod 4 abuts against the shielding cloth 3, the extension 12 can passively drive the arc-shaped block 10 away from the shielding cloth 3 until the contact rod 4 resets under the action of the first elastic element 5. Then the contact part 11 loses the abutment of the extension 12, so that the connecting rod 9 can reset under the action of the second elastic element, thereby driving the arc-shaped block 10 to abut against the shielding cloth 3. This can enrich the force feedback that the whole device provides to the user and further improve the feedback effect.

[0039] In another embodiment of the present invention, the inner wall of the movable cavity 2 is further provided with an inclined groove 13. The end of the inclined groove 13 near the shielding cloth 3 is closer to the abutting rod 4. A slider 14 is slidably connected in the inclined groove 13. A linkage rod 15 is hinged on the slider 14. The other end of the linkage rod 15 is hinged to the connecting rod 9. A folding plate 16 is hinged on the side of the extension 12 away from the shielding cloth 3. A third elastic member is provided on the extension 12 to force the folding plate 16 to abut against the extension 12. Specifically, under normal conditions, both the abutting rod 4 and the arc-shaped block 10 abut against the shielding cloth 3. At this time, the slider 14 is located at the end of the inclined groove 13 near the shielding cloth 3, and the folding plate 16 and the extension 12 are located between the slider 14 and the abutting part 11. When the protrusion 8 forces the abutting rod 4 closer to the shielding cloth 3, the extension 12 abuts against the abutting part 11, causing the connecting rod 9 to rotate passively, and the slider 14 slides appropriately in the inclined groove 13 (during which the slider 14 and the folding plate 16 do not contact each other). When the protrusion 8 forces the abutting rod 4 away from the shielding cloth 3, the folding plate 16 abuts against the slider 14 (correspondingly, the folding plate 16 abuts against the extension 12), so as to drive the slider 14 to slide along the inclined groove 13, thereby driving the arc-shaped block 10 and the abutting rod 4 away from the shielding cloth 3 together. Because the inclined groove 13 is inclined, as the abutting rod 4 moves away from the folding plate 16, the slider 14 gradually moves away from the abutting rod 4 until the slider 14 and the folding plate 16 separate. Then, the connecting rod 9 resets under the action of the second elastic element, thereby driving the slider 14 to reset and causing the arc-shaped block 10 to abut against the cover cloth 3, thus providing the user with a force feedback. Subsequently, the protrusion 8 and the connecting plate 6 separate, and the abutting rod 4 also resets under the action of the first elastic element 5, thereby driving the abutting rod 4 to abut against the cover cloth 3, providing the user with a second force feedback. During this process, the folding plate 16 abuts against the slider 14, forcing the folding plate 16 to overcome the elasticity of the third elastic element and avoid it, until the folding plate 16 and the extension 12 move again between the slider 14 and the abutting part 11. The folding plate 16 then abuts against the extension 12 again under the action of the third elastic element. During the process of the abutting rod 4 abutting against the cover cloth 3, the abutting part 11 is squeezed, causing the arc-shaped block 10 to move away from the cover cloth 3 again, until the abutting rod 4 resets, and the arc-shaped block 10 resets and abuts against the cover cloth 3, thus providing the user with rich force feedback.

[0040] In the above embodiments, the force feedback method is relatively monotonous. If there is a gap between the shielding cloth 3 and the user, the change in resistance force caused by the change in amplitude will be weakened, so that the user may not feel the change in force feedback, making it impossible for the user to distinguish the signal transmitted to the user by the vibration output mechanism (it is impossible to determine whether it is the signal corresponding to the first state or the signal corresponding to the second state). In this embodiment, an arc-shaped block 10 is added in the active cavity 2. When the drive wheel 7 drives the abutment rod 4 to run, the arc-shaped block 10 can be passively driven by the abutment part 11 and the slider 14, etc., to give the user a rich force feedback feeling. Moreover, when the vibration output mechanism is in the first state and the second state, the vibration amplitude, frequency and force of the abutment rod 4 and the arc-shaped block 10 felt by the user are different, so that the user can perceive what kind of signal the vibration output mechanism is output according to the vibration.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. 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 invention.
