Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, wherein the sensor device comprises:

the finger part 1 is suitable for being sleeved on a finger of a user and is bent along with the bending of the finger of the user;

the finger part 1 is provided with a finger sensor 11, and the finger sensor 11 is used for transmitting the motion of the finger part 1 to the controller 2;

the controller 2 sends a trigger signal after receiving the signal sent by the finger sensor 11;

wherein the controller 2 is connected to the finger sensor 11 through a signal line.

It can be understood that the number of the finger parts is 5, which respectively corresponds to 5 fingers on the palm, correspondingly, the number of the finger sensors is 5, which respectively corresponds to each finger part, and the finger parts comprise a thumb sensor 11a, an index finger sensor 11b, a middle finger sensor 11c, a ring finger sensor 11d and a little finger sensor 11e, the controller 2 is provided with 5 identical wire jacks, and the thumb sensor 11a, the index finger sensor 11b, the middle finger sensor 11c, the ring finger sensor 11d and the little finger sensor 11e are respectively connected with the 5 wire jacks on the controller 2 through signal lines; the controller 2 is also provided with a power switch for controlling the on-off of the power supply of the controller 2; the controller 2 is also provided with a power jack which is connected with an external power supply and used for electrifying the controller 2.

Like this, as control people's user, dress the sensor device on corresponding hand, finger portion 1 cover is established on the finger, wants to produce the motion control signal of a certain or some finger, just bends this or these finger, and the finger is crooked back, and finger portion 1 that the cover was established on the finger also can produce the bending, finger portion 1 has finger sensor 11, and finger sensor can detect the bending of finger portion to give the controller with the action signal transmission of finger portion, make the controller send trigger signal, this trigger signal is control signal. Thus, the control glove is worn on the hand of a user or another intact hand of a patient needing one hand to be rehabilitated), so that a control signal can be generated through the bending of the fingers of the user, the control signal is generated according to the control of the fingers of the user, frequent editing is not needed at a computer end and the like, the requirement on professional knowledge is low, and the control glove can be a family member of the patient or even the patient himself, so that the actual condition of the patient can be known more, and more accurate control signals can be generated.

The sensor is simple in whole and convenient to operate, the finger sensor is used for detecting finger movement, and the sensor has high sensitivity.

Preferably, the sensor device further includes a processor (not shown) connected to the controller, and configured to receive and process the trigger signal, so as to control the movement of the external auxiliary exercise glove.

It can be understood that, because the size of the palm of the user and the length of the fingers are different, the control glove can be freely controlled after a part of the users wear the control glove, and the control glove is inconvenient after the users wear the control glove.

The utility model discloses controller 2 pass through the signal line with finger sensor 11 connects, like this, to the less or short user of finger of palm, can adjust the shortening with the signal line to more person of facilitating the use dresses, improves user experience. Because the signal line material is comparatively soft, also can not do the processing, the signal line can be bent and shorten the distance between finger portion and the controller, directly uses. For users with large palms or long fingers, the signal wire can be replaced, and the signal wire between the controller and the finger part can be connected again, so that other parts are not affected, the universal device has high universality, can be produced in the same standard specification, and reduces the production cost. So that whatever length or size of palm, a trigger signal may be generated when the fingers move to the same or similar amplitude; meanwhile, the sensitivity of the finger sensor is modified through adjusting a circuit or modifying programming, the product yield is improved, the product can be adjusted to the target sensitivity by adjusting the sensitivity of the sensor, the target customer can be effectively targeted, and therefore the phenomenon that triggering is not flexible or is triggered mistakenly is avoided, and a better effect of generating a triggering signal is achieved.

Therefore, the control glove can adapt to the sizes of different hands, the sensitivity generated by the trigger signal can be adjusted, and a better control effect is achieved.

In a specific use, it is likely that a patient-glove-by-glove strategy will be adopted, i.e., in practice, the control glove is used primarily to adjust the sensitivity of the trigger signal, rather than to accommodate different hand sizes.

As shown in fig. 2 and 3, the finger sensor 11 includes at least one of the following sensors: a thumb sensor 11a that transmits a bending motion of the thumb; an index finger sensor 11b that transmits the bending motion of the index finger; a middle finger sensor 11c that transmits a bending motion of the middle finger; a ring finger sensor 11d that transmits a bending motion of the ring finger; and a little finger sensor 11e which transmits the bending motion of the little finger;

the individual sensors are separated from each other.

Therefore, the trigger signal can be generated only by partial fingers or a single finger according to the requirement of a user, so that the glove user can be controlled to select according to the actual requirement more conveniently; in addition, each sensor is separated from each other, so that actions among the sensors are not influenced mutually and are triggered independently, and therefore the generation of control signals cannot interfere with each other and is more accurate.

Wherein, the thumb sensor 11a is arranged on the thumb part and transmits the bending motion of the thumb to the controller 2 to generate a trigger signal.

The forefinger sensor 11b is provided on the forefinger portion, transmits the bending motion of the forefinger to the controller 2, and generates a trigger signal.
