Detailed Description
Embodiments of the present utility model will be further described with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and 2, a sensor according to an embodiment of the present utility model includes a first sensor unit 302, a second sensor unit 305, a transmitter (not shown), and a power source (not shown). The first sensor part 302 is mounted to the first holder 301, and the first holder 301 has a set length and width. The first and second sensor parts 301 and 305 may be provided on different fingers, respectively, such that the second sensor 305 slides along the length direction of the first holder 301 or the distance with respect to the first sensor part 302 varies, thereby detecting the spatial state or position of the user's finger. The transmitter, the power supply and the first sensor or the second sensor are connected to output different sensor signals according to different space states or positions of fingers.
In this embodiment, the first sensor member 302 is a permanent magnet, and the second sensor member 305 is a hall sensor. In this case, a transmitter (not shown) is connected to the second sensor part 305, and a power source (not shown) is used to supply power to the transmitter, the second sensor part 305.
In this embodiment, the second sensor component 305 is mounted to the second bracket 304, wherein,
the first holder 301 has a set length and width. It is understood that the first support may be a cuboid. A first sensor member 302 is provided on one side of the first holder 301, and a chute 303 extending in the longitudinal direction of the first holder 301 is provided on the side of the first holder 301 opposite to the side on which the first sensor member 302 is provided (i.e., the other side of the first holder 301).
The second bracket 304 is provided with a second sensor part 305, and the second bracket 304 is further provided with a slider portion 306 (refer to fig. 3) corresponding to the shape of the chute 303; that is, the profile of the slider member 306 is adapted to the chute 303 such that when the second bracket 304 contacts the first bracket 301, the slider member 306 engages the chute 303 and the slider member 306 is able to enter the chute 303 and slide along the chute 303 under the influence of an external force. In this manner, a user may generate control signals through different positional relationships of the first sensor component 302 and the second sensor component 305. It will be appreciated that the present embodiment does not limit the specific shapes of the slider member 306 and the chute 303; but the profile of the slider part 306 is adapted to the chute 303. For example: the slider member 306 in fig. 3 is a trapezoid, and the chute 303 in fig. 1 is correspondingly a trapezoid.
Further, the transmitter is configured to transmit a signal of the sensor or a control signal generated based on the signal of the sensor. In particular, the transmitter may output the sensor signal by wired or wireless means.
In the present embodiment, the first sensor member 302 has two; two first sensor parts 302 are provided at both ends of one side of the first holder 301 in the length direction thereof. The two first sensor parts 302 are arranged on the same side of the first holder 301. Preferably, two first sensor parts 302 are symmetrically disposed at both ends of the first holder 301, respectively. The chute 303 is provided on the center line of the first holder 301 in the width direction. Therefore, the overall appearance of the sensor is attractive, and the use perception of a user can be improved.
Wherein fig. 1 shows a positional relationship of a first bracket 301 and a second bracket 304 having two first sensor parts 302 upon contact, and fig. 2 shows the shape of a chute 303 and the above positional relationship from another direction or view; fig. 3 shows the shape of the slider portion 306 at the bottom or top of the second bracket 304.
In use, the sensor with two first sensor parts 302, the first and second holders 301, 304 are each disposed on a different finger of a user's palm, e.g. the first holder 301 is disposed on the thumb with the slider part 306 on the side adjacent to the index finger; and the second bracket 304 is disposed on one knuckle of the index finger such that the side of the chute 303 on the first bracket 301 is adjacent to the thumb. Thus, when the sensor is used, the slider portion 306 of the second bracket 304 can be slid along the slide groove 303 of the first bracket 301 by the action of the thumb, so that the sensor can judge the positional relationship between the second sensor member 305 and the two first sensor members 302 (the positional relationship also represents the relative positional relationship between the thumb and the index finger), and according to such a set positional relationship, signals of different or gradually changing sensors can be obtained. For example, when the second sensor unit 305 (for example, a hall sensor) gradually approaches one of the first sensor units 302 (for example, a permanent magnet N), a control signal corresponding to the sensor signal outputted therefrom causes the driving rotation output power of the motor to gradually increase; when the second sensor part 305 gradually approaches the other first sensor part 302 (e.g., the permanent magnet S), the control signal corresponding to the sensor signal outputted therefrom causes the driving brake output power of the motor to gradually increase. And when the second sensor block 305 is in the middle of the two first sensor blocks 302, neither the rotation nor the braking is driven. Preferably, the intermediate position of the second sensor component 305 between the two first sensor components 302 is the initial position of the second bracket or the second sensor component 30; to ensure the safety of the user using the sensor.
It should be noted that the first bracket 301 and the second bracket 304 may be disposed on different fingers by being disposed on a protective device (e.g., a glove), or may be disposed on corresponding fingers by a mounting member, such as a mounting belt, etc., so that the chute 303 and the slider member 306 are engaged or adjacent. When the second support 304 of the sensor is moved away from the first support 301 (where the first support 301 and the second support 304 are separated, e.g. by a spread finger), neither the first sensor part 302 senses the second sensor part 305 (or the second sensor part 305 senses the first sensor part 302) and the sensor outputs neither a brake nor a drive rotation signal.
In order to enhance the comfort of the user, the second bracket 304 is preferably cylindrical. Thus, when the second support 304 is disposed on the finger, when the finger needs to contact the outer periphery of the second support 304 to apply force, one arc segment of the outer periphery of the cylinder is adapted to the curved arc of the finger, and the second support 304 is also made to receive the force of the finger more sensitively. Further, in this case, in order to enhance the user's sense of use, it is preferable that the second sensor unit 305 is provided at the central region of the second bracket 304, so that the user can accurately grasp the force and position of moving the second bracket 304.
In some alternative embodiments, the first sensor component 302 is not limited to two, but may be one or more. For example; a first sensor member 302 is disposed at one end of the first bracket 301.
In an alternative, the first sensor part 302 on the first support 301 is a hall sensor and the second sensor part 305 is a permanent magnet. In this case, a transmitter (not shown) is connected to the first sensor member 302, and a power source (not shown) is used to power the transmitter, the first sensor member 302. It is understood that the hall sensor may be one or more than one, and the permanent magnet may be one or more than one.
In an alternative, the second sensor component 305 itself forms a structure corresponding to the runner of the first bracket 301, independent of the second bracket 304.
In an alternative, the change in position of the second sensor component 305 and the first sensor component 302 includes a relative slip, a change in distance, etc., which may be near and far.
In an alternative, the power source and/or the transmitter are spaced apart from the first sensor member, the second sensor member by a predetermined distance to be mounted on the arm of the user, both of which may be connected to the hall sensor by a cable.
