Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Example 1
As shown in fig. 1, the present embodiment provides a finger control device 50 including: a housing 11 wearable or mountable to a human body; a slide 13 provided to the housing 11; a permanent magnet 21 reciprocatable in the slide 13; a return elastic member 23 that returns the permanent magnet 21; a traction member 25 for pulling the permanent magnet 21, the traction member 25 being connected at a first end to the permanent magnet 21 and at a second end to a user's finger so as to pull the permanent magnet 21 against the return spring 23 in response to bending or stretching of the human finger. In this embodiment, the pulling member 25 is a pulling rope, and the second end of the pulling member 25 is connected to a finger ring 27, and the finger ring 27 is used for being sleeved on a finger of a user. In an alternative arrangement, the second end of the traction member 25 is connected to a finger cuff which is fitted over the user's finger and acts as a ring.
In use, the housing 11 may be secured to the arm of a user, for example in a wearable manner, or by means of a bandage. In this way, when the user's finger is bent or stretched, the permanent magnet 21 is carried by the traction element 25 against the return spring 23.
As shown in fig. 2 and 3, the finger control device 50 further comprises a sensor 33 mounted to the housing 11 and a power source for supplying power to the sensor 33, the sensor 33 being used to detect the motion state of the permanent magnet 21, e.g. to detect the position, direction of motion, speed of motion, etc. of the permanent magnet 21, thereby inferring the motion state of the user's finger, e.g. degree of flexion or diastole, speed, etc. The finger control device 50 further includes a transmitter mounted to the housing 11 and powered by the power source for wirelessly transmitting the detection signal of the sensor 33 or a control signal generated based on the detection signal. For example, when the pulling member 25 is attached to the user's finger from the back of the user's hand, as shown in FIG. 2, when the user's finger is substantially straight, the permanent magnet 21 is in the initial position, and is in close proximity to the sensor 33, and the permanent magnet 21 can detect the strongest magnetic field, which can be defined as the braking state, in which the braking force is strongest. As shown in fig. 3, when the user bends the finger from the substantially straight state of the finger, the finger ring 27 will pull the permanent magnet 21 against the return elastic member 23 through the pulling member 25 as the finger moves, so as to move the permanent magnet 21 away from the sensor 33, in this process, the permanent magnet 21 can detect that the magnetic field is gradually weakened, the braking force can be gradually reduced and finally the braking force is changed into driving force, and the driving force is increased as the permanent magnet 21 is farther away from the sensor 33 (i.e. the finger is bent to a higher degree). In this manner, the user may generate control signals via the finger.
In the present embodiment, the sensor 33 is a hall sensor; the finger control device further includes a circuit board 31 mounted within the housing 11, the sensor 33 and the emitter being mounted to the circuit board 31.
In this embodiment, the elastic restoring element 23 is a compressed spring, and the first end of the pulling element 25 is sleeved with the spring. The end of the slide 13 is provided with a limiting piece 15, and two ends of the return elastic piece 23 respectively abut against the permanent magnet 21 and the limiting piece 15, so that the return elastic piece is compressed between the permanent magnet 21 and the limiting piece 15.
As shown in fig. 4, in the present embodiment, the cross section of the slide 13 is circular, and the shape of the permanent magnet 21 is the same as or adapted to the shape of the slide 13 so as to reciprocate in the slide 13.
Example 2
Fig. 5 is a perspective view of a finger control device 50 according to a second embodiment of the present invention, fig. 6 to 8 show the permanent magnet in different positions of movement, respectively, and fig. 9 is a cross-sectional view of the finger control device 50. Compared to the embodiment shown in fig. 1, this embodiment has two main differences, one being that the cross-section of the slide 13 is square, the shape of the permanent magnet 21 is the same as the shape of the slide 13, and the shape of the permanent magnet 21 is adapted to the shape of the slide 13 for the reciprocating movement. Understandably, the cross-section of the slide 13 may also be of other shapes, for example polygonal, respectively the shape of the permanent magnet 21 is identical or adapted to the shape of the slide 13.
Another major difference is that the number of sensors exceeds one, and in this embodiment, the finger control device 50 has three sensors 33a, 33b and 33c, and the 3 sensors 33a, 33b and 33c are arranged at intervals along the direction of the slide 13 (i.e., the moving direction of the permanent magnet 21). The control precision of this kind of scheme is higher. For example, when the pulling member 25 is connected to the user's finger from the back of the user's hand, as shown in fig. 6, when the user straightens the finger, the restoring elastic member 23 assumes a natural state, and the permanent magnet 21 is closest to the sensor 33a, which can be defined as a maximum braking force state. After the user's finger is bent gradually, the pulling member 25 pulls the permanent magnet 21 against the return elastic member 23, and as the finger is bent gradually, the permanent magnet 21 gets away from the sensor 33a and gets close to the sensor 33b gradually, and the braking force becomes smaller gradually until the permanent magnet 21 reaches the state shown in fig. 7, at which time, the brake is neither braked nor accelerated. The user's finger continues to grip and the permanent magnet 21 gradually moves away from the sensor 33b and gradually approaches the sensor 33c, thereby gradually accelerating the state until the fist is gripped and the permanent magnet 21 reaches the state shown in fig. 8, which is the maximum acceleration state. In this manner, the user may generate control signals via the finger.
Example 3
Fig. 10 to 12 show the permanent magnet of the finger control device according to the third embodiment of the present invention in different positions. The main difference of the finger control device 50 of this embodiment compared to the embodiment shown in fig. 9 is having two permanent magnets 21a and 21b and 1 sensor 33. Preferably, the magnetic field installation directions of the two permanent magnets 21a and 21b are opposite to improve the detection accuracy; the permanent magnets 21a and 21b are connected together by a connecting member 22 to perform overall synchronous movement. As shown in fig. 10, when the user straightens the finger, the elastic reset element 23 assumes a natural state, and the permanent magnet 21b is closest to the sensor 33, which can be defined as a state of maximum braking force. After the user's finger is gradually bent, the pulling member 25 pulls the permanent magnets 21a and 21b against the return elastic member 23, as the finger is gradually bent, the permanent magnet 21b is gradually separated from the sensor 33, and the permanent magnet 21a is gradually close to the sensor 33, because the magnetic field installation directions of the permanent magnets 21a and 21b are opposite, the sensor 33 can detect a significant change in the magnetic field strength, and the braking force is gradually reduced in the process until the permanent magnets 21a and 21b reach the state shown in fig. 11, that is, the permanent magnets 21a and 21b move to both sides of the sensor 33, and at this time, the brake is neither braked nor accelerated. The user's finger continues to grip, the permanent magnet 21b gradually moves away from the sensor 33 and the sensor 21a gradually moves closer to the sensor 33, and because the magnetic fields of the permanent magnets 21a and 21b are mounted in opposite directions, the sensor 33 can detect a significant change in the polarity of the magnetic field, thereby gradually accelerating the state until the fist is gripped, and the permanent magnets 21a and 21b reach the state shown in fig. 12, which is the maximum acceleration state.
Example 4
As shown in fig. 13, a fourth embodiment of the present invention provides an electric board 100, wherein the electric board 100 includes a board body 60 and a wheel body 61 mounted on the board body, and further includes a finger control device 50. A receiver for receiving a signal transmitted from a transmitter of the finger control device 50 and a driver 62 for driving the plate 60 according to the signal received by the receiver, that is, controlling the movement of the plate 60 by driving the wheel 61, are installed below the plate 60. In this way, the user can control the movement of the plate body 60 of the electric board 100, such as forward, backward, acceleration, deceleration, etc., by bending and stretching the fingers.
In this embodiment, the electric board 100 is an electric skateboard, and the wheel body 61 is a roller. Understandably, the electric board 100 may be an electric surfboard, and the wheel body 61 is an impeller.
It will be appreciated that the finger control device 50, receiver and driver 62 may constitute a set of finger control devices that are not limited to application to electric skateboards or electric surfboards, but may be used in other fields.
In this embodiment, both the receiver and the driver 62 are mounted to the plate 60. In an alternative embodiment, the receiver is implemented as a remote controller, i.e. a signal generated by the finger control device 50 is received by the remote controller, which in turn controls the board body 60 according to the signal of the finger control device 50.
