Abstract
The utility model relates to an object contact type sensor. The object surface to be provided with a sensor is covered with a layer of soft and elastic light material with certain thickness such as sponge. A plastic film type micro-operation switch like a computer keyboard is arranged under the sponge. When a robot provided with the sensor encounters an obstacle, the surface sponge is pressed, and the pressure is absorbed by the sponge and transferred to the plastic film type micro-operation switch arranged at the reverse side. That is to say, the micro-operation switch is pressed down directly, so the robot can sense that an obstacle exists at some direction.
Description
Technical field:
The utility model relates to a kind of contact type sensor of object, is mainly used in electrical category object disturbance of perception things in moving process such as robot.
Background technology:
Often need disturbance of perception thing in moving for the object that moves such as robot, microswitch commonly used is installed on the contact-making surface as sensor, need to install a plurality of, the spring or the elasticity of spring leaf of microswitch are harder, flexible gap is less, robot can not stop because of reasons such as inertia after perceiving barrier, might break thing, perhaps robot itself is hit partially, because this cause is just usually used non-contact sensors such as ultrasonic wave or photoelectricity in actual use, but because sensor costs such as ultrasonic wave are higher, and there are shortcomings such as blind area, be with contact type sensor auxiliary detection such as microswitches.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of elasticity softer, and the contact type sensor that flexible gap is bigger as people's skin, designs " skin " cheaply at the concrete pressurized of a kind of resilient energy perception position for robot.
The purpose of this utility model reaches by following design: covering one deck on the robotic surface of need sensor installation or shell has certain thickness softer elastomeric light material such as sponge, and what install under sponge is mechanical type or condenser type or conductive rubber formula or Plastic Diaphragm Type Servomotor microswitch as computer keyboard.When the robot that the sensor is installed runs into barrier, the sponge pressurized on surface, pressure is absorbed by sponge and is delivered on the microswitch of the Plastic Diaphragm Type Servomotor of reverse side or other type, be equivalent to microswitch and directly depressed, but robot has just run into barrier on a certain direction of perception like this.Because sponge is very soft, can transmit pressure again, as long as the microswitch elasticity of selecting is not very hard, be to utilize sponge to cooperate with microswitch, produce a kind of contact type sensor of crashproof object---through overtesting, every certain thickness sponge subdue to common keyboard, what depress earlier is keyboard, is only sponge then.This sensor can utilize the tension force of sponge itself to be fixed on the position of the required installation of robotic surface, has characteristics such as technology is simple, easy for installation, cheap reliable, especially in the mobile model robot---application promise in clinical practice is arranged on such as dust-collecting robot.

Specific embodiments:
Add that with the most cheap sponge the Plastic Diaphragm Type Servomotor switch is an example: sponge 1 is designed to tabular or is designed to hollow cuboid or shape such as cylinder, cone, spheroid, parcel or hang or adhere on the position that needs sensor installation on the shell of robot, or utilize the tension force of sponge itself, be sleeved on the shell of robot, as Fig. 1, Fig. 2, Fig. 3; Be covered with three layers of book film for 1 time in sponge: input film 2, barrier film 3, output film 4, have many through holes 6 on the barrier film 3, be arranged between input film 2 and the output film 4.Input film 2 downsides all cover with output film 4 upper sides puts conducting film 5, as Fig. 4; Or input film 2 downsides and output film 4 upper sides open empty 6 position at the barrier film 3 of centre and all cover and put conductive contact 7, as Fig. 6; Or input film 2 downsides and output film 4 upper sides simultaneously cover and put conducting film 5, another side and open empty position at the barrier film 3 of centre and all cover and put conductive contact 7, and as Fig. 5, the conducting film or the conductive contact of above-mentioned input film 2, output film 4 all have a lead to draw; Or input film 2 downsides all cover to put conducting film 5 that no lead draws or all cover at the position that the barrier film 3 of centre is opened sky and put mutual disjunct conductive contact 7, output film 4 upper sides the barrier film 3 of centre open empty 6 position cover put two-way apart from one another by but the exposed printed wire contact 8 that do not communicate, as Fig. 7.Above-mentioned conducting film 5 or conductive contact 7 can belong to material or conductive rubber or the made film of other conductive materials by pure gold.Connection lead on input film 2, the output film 4 between each contact is generally printed wire.What perhaps, install under sponge is mechanical type as computer keyboard or condenser type, the conductive rubber moving switch that declines.When robot runs into barrier, the sponge pressurized on surface, pressure is absorbed by sponge and is delivered on the microswitch of the Plastic Diaphragm Type Servomotor of reverse side or other type, be equivalent to microswitch and directly depressed, but robot has just run into barrier on a certain direction of perception like this.
Usually switch output all is that low level is effective: i.e. being output as low level during conducting, is high level during disconnection.So if the input film has lead to pick out---at illustration 4~illustration 6, this lead connects low level usually---logically, output film lead is drawn and is connect logic circuit or single-chip microcomputer.At illustration 7, the input film does not have lead and picks out, and two line conductors one tunnel of output film connect low level, and one the tunnel connects logic circuit or single-chip microcomputer.
If need know that in some specific occasions robot is accurate to concrete certain position in certain direction and whether runs into barrier, can will have only on the original a certain direction switching signal output change multiple signals output into---as the button of the keyboard of computer or some electronic equipments, can a plurality of microswitches that are not connected in parallel be set the sponge on certain one side or several for 1 time.
Input film 2 described in the utility model typically refers to the input low level that is coated with conducting film 5 or conductive contact 7 or that tunic of high level (being generally low level), output film 4 is meant that tunic of the signal output that on off state can be changed, but it is not absolute, when the situation of a plurality of microswitches not in parallel is installed on certain direction, convenient for winding displacement, also can have on the input film 2 on output signal line, the output film 4 and also input signal cable can be arranged.Barrier film 3 plays in normality---and film does not have under the situation of pressurized, isolates input film 2 and the contact of output film 4 or the effect of lead.One of them can condense together input film 2 or output film 4 with elastomeric light material 1, and one in input film 2 or the output film 4 also can condense together with body surface: be printed substrate as body surface.To import generally that film 2 places on the barrier film 3, output film 4 places barrier film 2 times, and place on the barrier film 3, import film 2 and place barrier film 3 times also passable but will export film 4.At illustration 7, because printed wire is more on the output film 4, as be placed in 1 time pressurized of sponge, have influence on the reliability of printed wire through regular meeting's local deformation, place body surface so generally will export film 4, the input film 2 that has only the contact is placed sponge 1 time.
Input film 2, barrier film 3, output film 4 can hang or holding or stickup or be screwed and be installed on robotic surface.The signal input of input film 2 or output film 4, output lead can be designed to the continuity of plait shape and place the edge that inputs or outputs film, or it is fixing or paste or be pressed on input, export on the film, perhaps fix and draw with conductive rubber, fixing, the holding wire setting of above-mentioned book membrane type microswitch, the method for drawing have mature technique as the book membrane type keyboard of electronic equipment, and the utility model is not described in further detail.
The outer surface of spongy elastomeric light material itself or some lappings that add can be designed to the different shape than hommization---and such as cartoon type etc., it is attractive in appearance to increase that appearance also can stamp color or literal.The ground of the sensor of other type or charging reed or heat radiation, steam vent will be installed originally can open some windows on sponge and plastic sheeting, the top or the bottom that perhaps these things are arranged on robot do not cover the place of sponge.The thickness of spongy elastomeric light material generally can be designed to more bigger than the beeline of robot stepping, and robot can in time be stopped after perceiving barrier.
The utility model is mainly used in object disturbance of perception thing usefulness such as robot, on the button of present general calculation switch dish or some electronic equipments, this utility model is suitable equally: the sponge of available cheapness replaces the resilient rubbber cushion of spring or projection, can reduce the cost of keyboard or button.
