The novel multifunctional clothes hanger is small and exquisite in whole, easy to carry, simple to wear and use, safe and efficient, and cannot generate negative effects on a human body.

It is worth mentioning that the wearable keyboard 100 in the scheme can be only one and worn on the finger of the dominant hand, and correspondingly, the keys knocked by five fingers on one hand can only be detected under the situation, different input logics need to be designed at the moment, and the user can normally use the wearable keyboard after learning the input logics. Similarly, the wearable keyboards 100 in the present scheme can also be two and worn on two hands respectively, and at this time, the two wearable keyboards 100 detect the keys knocked by ten fingers on the two hands respectively, and this kind of mode need not to learn new input logic, can correspond individual case positions on the keyboard according to standard fingering and perform touch typing, and the wearable keyboard 100 on the same hand can correspond to the knocking action on different positions by different fingers and feed back different letters. Wearable keyboard 100 is whole to be the loop configuration in this scheme, and is whole small and exquisite pleasing to the eye, can also design through the customization to the shell and be the required shape of user, still can regard as the ornament to dress when not using, does not influence the normal function of hand, and whole quality bears a burden lightly and convenient to carry just beautifully for a short time. In the preferred mode of wearing with both hands in this embodiment, in this mode, the typing habit of the user still can be input according to traditional keyboard button, need not to edit the information input logic of row, and the user also need not learn new input logic method, and the logical cost of manufacturing and the use and study cost of user all reduce.

In this embodiment, the wearable keyboard 100 can be worn on any finger, and correspondingly on different fingers, and the logic for detecting the remaining fingers needs to be modified correspondingly.

The distance measuring device 20 in the present embodiment mainly aims to detect the motion of each finger, and there are various embodiments that can implement this function, and the following are two realizable embodiments provided in the present embodiment:

the first embodiment is as follows:

the distance measuring device 20 in this embodiment includes a distance measuring transmitter 21 and a distance measuring receiver 22, the setting positions of the distance measuring transmitter 21 and the distance measuring receiver 22 are mainly for detecting the knocking action of the finger, so the positions of the parts of the finger have multiple possibilities, and the scheme only adopts an implementation mode as follows: the ranging transmitters 21 and ranging receivers 22 are disposed in one-to-one correspondence and surround the housing 10. The distribution positions of other distance measuring devices 20 are protected in the present embodiment without improvement.

Including being used for detecting the first range unit 20 of thumb action and at least being used for detecting the second range unit 20 of the other fingers outside the thumb, range unit 20's quantity is the forward relation with the precision that detects, and more range finding transmitter 21 and range finding receiver 22 can collect more information, and the data feedback that corresponds is also more accurate. Meanwhile, because the volume of the wearable keyboard 100 in this embodiment is not large, the number of the distance measuring devices 20 is basically required, and then the control is performed according to the actual limited spatial distribution and the cost. Preferably, the second distance measuring devices 20 have at least six groups and are uniformly arranged in the casing 10 at intervals, and the first distance measuring devices 20 are arranged between two adjacent groups of the second distance measuring devices 20 along the symmetry line of the casing 10 (as shown in fig. 4).

When worn, the first distance measuring device 20 is located directly below the wearable keyboard 100 for detecting a tap confirmation action of the thumb. Simultaneously for the accuracy that detects, when the wearing hand is the left hand, first range unit 20 was located the below of wearable keyboard 100 symmetrical line and is inclined to the right this moment, and when the wearing hand was the right hand, first range unit 20 was located the below of wearable keyboard 100 symmetrical line and is inclined to the left this moment, can be more accurate measure the action of knocking of corresponding thumb through shortening first range unit 20 and the distance that corresponds the thumb. The second distance measuring device 20 is symmetrically distributed on two sides and is arranged at three annular intervals, wherein the distance measuring emitter 21 can be an infrared emitter or a laser emitter, and the emitting direction of the distance measuring emitter 21 is a direction extending from the central point of the wearable keyboard 100 to the corresponding distance measuring emitter 21. Taking the detection of the tap action of the thumb as an example, the infrared emitter or the laser emitter is opposite to the first section of the thumb, when the thumb is not tapped, the distance measurement data (voltage) from the middle finger to the first section of the thumb is stabilized at a value, the thumb is lifted for a short time period (the tap action occurs) during tapping, and at the time, the distance measurement data can be changed, so that the tap action known by the thumb is judged. The detection of the other fingers is the same as the above-mentioned way, and is not described herein.

Because the angle of the light emitted by the infrared emitter or the laser emitter is limited, usually 5-15 degrees, the up-and-down moving direction of other fingers at two sides of the wearing finger in the range is difficult to confirm, and the feedback corresponding to the key position of the knocking key is not accurate enough. Preferably, equally set up a range finding receiver 22 in two range finding transmitter 21's that lie in horizontal symmetry line upper and lower both ends respectively in this embodiment, can cooperate other two range finding receivers 22 of same side upper and lower through this setting to judge that the direction that other fingers of wearing finger both sides hit is the top or the below, ensures feedback information's accuracy.

Taking the position of the nail of the middle finger of the left hand wearing the wearable keyboard 100 (subsequently called as "ring") as an example, the ranging transmitter 21 and the ranging receiver can collect the actions of the other fingers of the left hand when the key is knocked, and the other fingers are not moved and the middle finger of the left hand is knocked, and output the distance and the relative distance data, and finally judge which key position the knocking action occurs according to the change situation of the distance, specifically, when the middle finger of the left hand is worn with the "ring" at the default D key position, the ranging receivers 7 and 8 mainly detect F, G keys of the two right key positions, the ranging receivers 5 and 6 mainly detect S, A keys of the two left key positions, the ranging receiver 3 (matching with the ranging receiver 8) at the upper part of the "ring" mainly detects R, T keys of the two right key positions, and the ranging receiver 4 (matching with the ranging receiver 5) mainly detects W, W, Q, the ranging receiver 1 (matching with the ranging receiver 6) at the lower part of the 'ring' mainly detects X, Z of the two keys on the left side, the ranging receiver 2 (matching with the ranging receiver 7) mainly detects V, B of the two keys on the right side, and the ranging receiver 9 mainly detects the hitting of the thumb on the space key. Similarly, when the wearing hand is the middle finger of the right hand, the default position is the position of the J key, and the rest detection is the same as the method, and is not repeated herein.

Wherein, it is worth to state that, the realization scheme of A key position: under the condition that the middle finger of the left hand is worn with the finger ring, the key A of the left hand can be shielded by the ring finger when the little finger is knocked, and the mode can be changed in such a way that when the key A is knocked, the ring finger and the little finger are lifted together, the little finger firstly simulates the key A knocking and then falls down, or the key A is defined as the key TAB on the left side of the key Q. When the wearing hand is the right hand, "; the key position is realized in a manner similar to that described above, and is not described herein.

Example two:

the distance measuring device 20 in this embodiment is a distance measuring radar, and the distance measuring radar (implementing functions by distance measurement) commonly includes: infrared range radar, laser range radar, and millimeter wave range radar. The application of the distance measuring radar on the sweeping robot is referred, the distance measuring radar is applied to the wearable keyboard 100, the high-speed distance measuring radar has a better effect due to the fact that the distance measuring points are many and dense, the action when the keys of other fingers on the wearing fingers are knocked is collected, the knocking action is carried out on middle fingers of the wearing fingers due to the fact that the other fingers are not moved, the distance and the relative distance data are output in a mode, and finally the knocking action is judged according to the change situation of the distance at which key position occurs.

In the above two embodiments, the attitude angle of each finger is further detected by the attitude angle detection device 30, wherein the attitude angle detection device 30 includes a three-axis acceleration sensor and a three-axis gyroscope. Most of the existing triaxial acceleration sensors adopt piezoresistive, piezoelectric and capacitive working principles, and the generated acceleration is in direct proportion to the change of resistance, voltage and capacitance and is acquired through corresponding amplifying and filtering circuits. This and ordinary acceleration sensor is based on the same principle, so in certain technology three single axes can become a three-axis. And the three-axis gyroscope can measure the positions in six directions, move tracks and accelerate. The three-axis gyroscope has the greatest function of measuring angular velocity to judge the motion state of an object, and is also called as a motion sensor.

Similarly, taking the wearable keyboard 100 (hereinafter referred to as a "ring") worn at the position of the fingernail of the middle finger of the left hand as an example, when the knocking action occurs, the built-in acceleration sensor calculates the attitude angle, obtains the included angle between the fingernail and the desktop and the acceleration of the knocking action of the finger in real time, and simulates the knocking. For example, the angle between the fingernail and the upper half of the desktop is an obtuse angle when the key E is struck, a right angle when the key D is struck, and an acute angle when the key C is struck. Because when different fingertips carry out knocking actions at different positions (particularly Q line and Z line), the hand can naturally slightly displace and incline along with the matching knocking actions, the detection can assist in judging whether the current knocking action of the human hand is default line A or digital line, Q line or Z line (obtuse angle of Q line, right angle of A line and acute angle of Z line, obtuse angle of digital line is larger than that of Q line), and misoperation is reduced. Correspondingly, when other fingers hit the key positions, corresponding acceleration data can be obtained to assist in judgment, and details are not repeated herein.

When the wearing finger is the thumb, the distance measuring device and the attitude angle detecting device on the thumb can respectively and correspondingly detect the rest four fingers, and the problem of shielding does not exist under the condition. The detection is more accurate.

In the normal use process, the keyboard and the input of the knocking information need to be provided with an input main body, and the corresponding connection mode with the main body also needs to be provided, including various types such as wired connection or wireless connection. This scheme still sets up the wireless connection device that is used for being connected with the host computer for the convenience of use at the control mainboard, and wherein wireless connection device can be for bluetooth connection or USB multiple mode of pegging graft, satisfies the use of being connected of this scheme and other equipment.

The control main board is also provided with invalid judgment on the knocking action, and when the distance measuring receiver 22 detects that the time interval of the stopping of one knocking action at the same position is too long, the knocking action is regarded as invalid, so that the input error is also avoided. Preferably, a sound or voice prompt or an element containing a vibration prompt can be correspondingly added to the control main board, but when invalid judgment occurs, the user can be reminded through the sound, the voice or the vibration.

In this embodiment, the wearable position of the wearable keyboard 100 is not limited in particular, and the wearable keyboard can be worn on the end of a finger close to a fingernail, and can also be worn on the second knuckle, the third knuckle, and the like of the finger. The shape of the casing 10 in this embodiment may be designed as a ring-shaped casing 10 for being fitted around a finger, or as a hemispherical casing 10 for being fitted around a fingertip end. Simultaneously casing 10 adopts the material that has deformation to make, casing 10 adopts silica gel to make, and casing 10 that this kind of material was made not only can play the protection effect to inside part, and the silica gel material has flexible deformation's characteristic simultaneously, can adapt to the wearing demand of different people, different fingers, also prevents to take place the phenomenon that drops wearing the in-process.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
