Abstract
The invention provides a shockproof bed. The shockproof bed can drive two bed plates to rotate, simultaneously enables the bed plates to horizontally move towards two sides of a bed frame so as to enlarge a falling space for the human body to fall between the two bed plates and prevent the human body from being extruded by the two bed plates when the human body falls, and simultaneously enlarges a space in the bed frame for accommodating the human body. The shockproof bed comprises the bed frame, a left bed plate, a right bed plate and an overturning driving mechanism, wherein the left bed plate and the right bed plate are of split type, and the overturning driving mechanism enables the left bed plate and the right bed plate to rotate in opposite directions and enables the human body on the left bed plate and the right bed plate to fall into the bed frame. When the human body fall into the bed frame, the left bed plate and the right bed plate can be driven by the overturning driving mechanism to shade above the human body, and the left bed plate and the right bed plate are further connected with horizontal movement driving mechanisms driving the left bed plate and the right bed plate to respectively move towards the left side and the right side.
Description
Technical field
The present invention relates to a kind of Antiseismic bed.
Background technology
Chinese patent application CN101874689A discloses a kind of Antiseismic bed, comprise bedstead, on bedstead, be provided with two along bedstead long axis and the bed board axle that can rotate, on every bed board axle, be fixed with respectively a bed board, between described bedstead and bed board, be provided with and can make two bed boards rotate and make to be positioned at towards rightabout the turnover driving mechanism (being the actuating unit described in its file) that human body on bed board falls into bedstead, and bed board described after in human body falls into bedstead can block above human body under turnover driving mechanism drives, described turnover driving mechanism is connected with control circuit, on control circuit, be connected with the pressure sensor and the seismic sensor that are arranged on bedstead.When there is earthquake, pressure sensor and seismic sensor detect after relevant signal, by control circuit, turnover driving mechanism is moved, the human body that drives two bed boards to rotate and make to be positioned on bed board towards rightabout falls into bedstead, and makes two bed boards form firm triangle under turnover driving mechanism drives to block above human body.
But the problem of this Antiseismic bed is, turnover driving mechanism can only drive two bed boards to rotate with bed board axle, bed board axle can only rotate with respect to bedstead, this can produce two problems: one, because the wheelbase of two bed board axles is little, human body falls and can cause extruding from being fixed between two bed boards two bed board axles; Two, two bed boards block the top in human body after bed board axle rotates, and the space that holds human body in bedstead is less.
Also there is the problem how two bed boards synchronously rotate under the drive of turnover driving mechanism in it in addition.Because; if both are asynchronous; two bed boards are when blocking above human body; the lateral edge portion of two bed boards just may not contact; thereby can not form firm triangle; when there being weight to fall on two bed boards time, two bed boards are likely shifted, and can not protect the human body that is positioned at its underpart.
Summary of the invention
The object of this invention is to provide a kind ofly when can drive two bed boards to rotate, make bed board to the both sides translation of bedstead, to increase human body from the space that falls between two bed boards, prevent from by two bed boards, being pushed when falling; Increase the Antiseismic bed that holds the space of human body in bedstead simultaneously.
This Antiseismic bed, comprises bedstead, two split type left and right bed boards; Can make two left and right bed boards rotate and make to be positioned at towards rightabout the turnover driving mechanism that human body on the bed board of left and right falls into bedstead, and left and right bed board described after in human body falls into bedstead can block above human body under turnover driving mechanism drives, left and right bed board also with drive its respectively to the left and right the translational drive mechanism of two side shiftings be connected.
Beneficial effect of the present invention: this Antiseismic bed is owing to possessing turnover driving mechanism and translational drive mechanism simultaneously, turnover driving mechanism drives two left and right bed boards to rotate towards rightabout, and translational drive mechanism can drive left and right bed board difference two side shiftings to the left and right, like this, because left bed board is to moving to left, right bedboard moves right, and the distance between two bed boards is larger, and human body falls Shi Buhui from two bed boards and pushed by two bed boards; Left and right bed board blocks after rotating when the top of human body, and the space in the bedstead of the bottom between the bed board of left and right will increase.
Make left and right bed board can realize rotation, can realize translation again and realize than being easier to, fairly simple a kind of structure is, translational drive mechanism comprises left and right bed board axle, left and right slide block, two translation oil cylinders or cylinder; Left and right bed board is fixedly linked with left and right bed board axle respectively, and left and right bed board axle rotates respectively that be arranged on can be on the left and right slide block of bedstead two Slideslips, and left and right slide block is connected with driving its translation oil cylinder horizontally slipping or cylinder respectively; For the turnover driving mechanism that drives left and right bed board axle to rotate with respect to left and right slide block, left and right slide block is set.
Certainly, if turnover driving mechanism and translational drive mechanism are united two into one, can simplified structure, for this reason, above-mentioned Antiseismic bed, it also comprises the actuating unit that drives bed board upset and translation, this actuating unit be turnover driving mechanism be also translational drive mechanism, this actuating unit comprises the left and right bed board axle being fixedly linked respectively with left and right bed board, left and right bed board axle is slidably arranged in respectively in the left and right chute on bedstead, the end of left and right bed board axle arranges left and right driven wheel, the up and down two piece left worm screws parallel with left chute mesh with the top and the bottom of left driving worm gear respectively, the up and down two piece right worm screws parallel with right rail mesh with the top and the bottom of right driving worm gear respectively, upper left worm screw and upper right worm screw are fixed on bedstead, bottom left worm screw is connected with left sliding sleeve, left sliding sleeve is connected by the left sliding pair axially sliding mutually with the output shaft of left drive unit, bottom right worm screw is connected with right sliding sleeve, right sliding sleeve is connected by the right sliding pair axially sliding mutually with the output shaft of right drive unit.
When left drive unit action, left drive unit output shaft rotation, drives left sliding sleeve to rotate, and bottom left rotates by worm screw.And upper left worm screw to be fixed on bedstead be motionless, when the left driven wheel therefore all meshing with bottom left worm screw and upper left worm screw can only rotate and roll along upper left worm screw.Left driven wheel rotates, and left bed board axle rotates, and drives left bed board to rotate; Left driven wheel rolls along upper left worm screw, has just realized the translation to bedstead left side of left bed board axle.That is to say, rotate on left bed board limit, and move to the left on limit.Until left bed board axle contacts with the left end of left chute, left bed board axle stops to the translation in bedstead left side.In like manner, when right drive unit action, right drive unit output shaft rotation, drives right sliding sleeve to rotate, and bottom right rotates by worm screw.And upper right worm screw to be fixed on bedstead be motionless, when the right driven wheel therefore all meshing with bottom right worm screw and upper right worm screw can only rotate and roll along upper right worm screw.Right driven wheel rotates, and right bedboard axle rotates, and drives right bedboard to rotate; Right driven wheel rolls along upper right worm screw, has just realized the translation to bedstead right side of right bedboard axle.That is to say, rotate on right bedboard limit, and move to the right on limit.Until right bedboard axle contacts with the right-hand end of right rail, right bedboard axle stops to the translation on bedstead right side.At this moment left bed board and right bedboard form triangle, and the human body of bedstead is formed to protection.Due to left bed board translation to the left, right bedboard is translation to the right, and the space in the bedstead of the bottom between left bed board and right bedboard is increased.
In order to make two bed boards synchronously overturn, above-mentioned Antiseismic bed, also comprises two of two left and right synchronous fuel tank or cylinder; The piston rod of left synchronous fuel tank or cylinder is connected with left sliding sleeve or bottom left worm screw, and the piston rod of right synchronous fuel tank or cylinder is connected with right sliding sleeve or bottom right worm screw; The structure of left and right synchronous fuel tank or cylinder is identical; The rod chamber of left and right synchronous fuel tank or cylinder communicates by pipeline, and the rodless cavity of left and right synchronous fuel tank or cylinder communicates by pipeline.By synchronous fuel tank or cylinder, left and right bed board is synchronously rotated, simultaneously also reduced that bed board is clamped human body and the possibility that injures human body.

The left end of bottom left worm screw 45 is connected with the left axis of guide 47, and right-hand member is connected with left sliding sleeve 46.The left axis of guide 47 is slidably arranged in the left support abutment 48 being fixed on bedstead, left support abutment plays guiding, supporting role to the left axis of guide, also bottom left worm screw 45 moved axially to position-limiting action (when bottom left worm screw 45 is moved to the left after certain distance, its left part 451 contacts with left support abutment right part 481 and can not be moved to the left).The output shaft 200 of left sliding sleeve 46 and reductor 400 is connected by the spline pair of axially slide mutually (but circumferentially can not relatively rotate).
The right-hand member of bottom right worm screw 55 is connected with the right axis of guide 57, and left end is connected with right sliding sleeve 56.The right axis of guide 57 is slidably arranged in the right support abutment 58 being fixed on bedstead, right support abutment plays guiding, supports the right axis of guide, also bottom right worm screw 55 moved axially to position-limiting action (when bottom right worm screw 55 moves right after certain distance, its right part 551 contacts with right support abutment left part 581 and can not move right).The output shaft 200 of right sliding sleeve 56 and reductor is connected by the spline pair of axially slide mutually (but circumferentially can not relatively rotate).
The output shaft 200 of upper left worm screw 44, bottom left worm screw 45, left chute 41, upper right worm screw 54, bottom right worm screw 55, right rail 51, left sliding sleeve 46, right sliding sleeve 56, the left axis of guide 47, the right axis of guide 57, reductor all parallels or coaxially.
Upper left worm screw 44, bottom left worm screw 45 mesh with the top and the bottom of left driving worm gear 42 respectively; Upper right worm screw 54, bottom right worm screw 55 mesh with the top and the bottom of right driving worm gear 52.
The piston rod 49 of left synchronous fuel tank 82 is connected with the left axis of guide 47 by a rebound 71, and the piston rod 59 of right synchronous fuel tank 92 is connected with the right axis of guide 57.Referring to Fig. 5, the structure of left and right synchronous fuel tank is identical; The rod chamber of left and right synchronous fuel tank communicates by pipeline 93, and the rodless cavity of left and right synchronous fuel tank communicates by pipeline 83.
On the axial direction of the left axis of guide 47, be provided with the left travel switch being fixed on bedstead, on the axial direction of the right axis of guide 57, be provided with the right travel switch being fixed on bedstead.
Rear left worm screw 81 and rear right worm screw 91 are fixed on tailstock plate 13.Left driven gear 43 and 81 engagements of rear left worm screw, right driven gear 53 and 91 engagements of rear right worm screw.
Motor 300 is connected with the power shaft of reductor, and the output of left travel switch and right travel switch is received for controlling the control circuit of motor.
When normal condition, referring to Fig. 3,4, two left and right bed board docking, form one flat plate and be positioned on bedstead.When the relevant sensor in control circuit detects earthquake generation, motor action, the output shaft rotation of reductor, drives sliding sleeve (left sliding sleeve, right sliding sleeve) to rotate, and lower worm screw (lower-left worm screw, bottom right worm screw) is rotated.And upper worm screw (upper left worm screw, upper right worm screw) to be fixed on bedstead be motionless, when the driven wheel (left driven wheel, right driven wheel) therefore all meshing with lower worm screw and upper worm screw can only rotate and along upper worm screw roll (left driven wheel rolls to the left, right driven wheel rolls to the right),, lower-left worm screw (and left sliding sleeve and left axis of guide) is moved to the left vertically when rotating, and bottom right worm screw (and right sliding sleeve and right axis of guide) moves right vertically when rotating.Like this, left bed board axle rotates and along left chute to left, drives left bed board to rotate and to left; Right bedboard axle rotates and along right rail to right translation, drives right bedboard to rotate and to right translation.
Before left and right bed board is from horizontal (normally) state turnover that is positioned at horizontal level to vertical position, Action of Gravity Field due to left bed board, left driven wheel is to the generation of lower-left worm screw thrust to the right, lower-left worm screw and left sliding sleeve are pressed on to the right on speed reducer output shaft all the time, and lower-left worm screw (and left sliding sleeve and left axis of guide) can not move axially; In like manner, Action of Gravity Field due to right bedboard, right driven wheel, to the generation of bottom right worm screw thrust left, is pressed on speed reducer output shaft bottom right worm screw and right sliding sleeve left all the time, and bottom right worm screw (and right sliding sleeve and right axis of guide) can not moved vertically yet.
Certainly, when left and right bed board is from horizontal (normally) state turnover that is positioned at horizontal level to crossing vertical position, Action of Gravity Field due to left and right bed board, left driven wheel is to the generation of lower-left worm screw thrust left, right driven wheel is to the generation of bottom right worm screw thrust to the right, because sliding sleeve (left sliding sleeve, right sliding sleeve) can be with respect to speed reducer output shaft at axial relative sliding, thereby the left axis of guide (bottom left worm screw, left sliding sleeve) is moved to the left, and the right axis of guide (bottom right worm screw, right sliding sleeve) moves right.
When left and right bed board is from horizontal (normally) state turnover that is positioned at horizontal level to crossing vertical position, the left axis of guide being moved to the left is vertically encountered left travel switch, or, by the right axis of guide moving left, encounter right travel switch vertically, control circuit is controlled motor and is stopped action.When the power of motor is cut off, its speed reducer output shaft does not rotate, but because having turn to, left and right bed board crosses vertical position, at this moment left bed board can clockwise rotate because of Action of Gravity Field still continuation, right bedboard can rotate counterclockwise because of Action of Gravity Field still continuation, so left and right bed board axle still can rotate.Left and right bed board axle rotates, left and right driven wheel must rotate, and inevitable translation when rotating of left and right driven wheel (left bed board axle rotates and to left, right bedboard axle rotate and to right translation), like this, lower-left worm screw (and left sliding sleeve and left axis of guide) rotate and under the drive of the left driven wheel of left with respect to speed reducer output shaft slide left vertically (speed reducer output shaft does not rotate), bottom right worm screw (and right sliding sleeve and right axis of guide) rotate and under the drive of the right driven wheel of right translation with respect to speed reducer output shaft slide to the right vertically (speed reducer output shaft does not rotate).Until left bed board axle contacts with the left end of left chute, right bedboard axle contacts with the right-hand member of right rail, and left bed board axle and right bedboard axle stop translation, and the upper end in contact of left and right bed board forms firm triangle (referring to Fig. 1,2).Left and right bed board is from horizontal (normally) state turnover that is positioned at horizontal level to crossing vertical position; when human body is jammed; because reductor does not rotate; pressure is little; thereby it is injured to reduce human body; and people can firmly push bed board open, human body can enter in a body, to reach the effect of protection human-body safety.
Four pressure sensors 500 are arranged on the below, four bights of bedstead, and support on the ground.Four pressure sensors are for detection of the weight of whole bed.On bed, sleep while having people, pressure sensor detects pressure and becomes large, and its output signal is to control circuit, and motor just may move.On bed, during nobody, the pressure that pressure sensor detects does not increase, and has both made seismic sensor vibration signal be detected, and control circuit can not send signal yet and make motor action.More smooth in the process of upset translation for left and right bed board, left driven gear 43 meshes with rear left worm screw 81, right driven gear 53 and 91 engagements of rear right worm screw.In driven wheel rotation translation process, driven gear (left driven gear, right driven gear) rotates and translation with respect to rear worm screw (rear left worm screw, rear right worm screw).
Horizontal (normally) state variation that Antiseismic bed recited above is arranged in horizontal level from its left and right bed board forms the process of leg-of-mutton guard mode to left and right bed board; the left part 451 of bottom left worm screw 45 does not contact with the right part 481 of left support abutment 48 all the time, and the right part 551 of bottom right worm screw 55 does not contact with the left part 581 of right support abutment 58 all the time.From guard mode, change and return to difference of horizontal (normally) state, brief description changes to the process of horizontal (normally) state from guard mode.
Motor obtains electric rotation, and the output shaft rotation of reductor drives sliding sleeve (left sliding sleeve, right sliding sleeve) to rotate, and lower worm screw (lower-left worm screw, bottom right worm screw) is rotated.Because left sliding sleeve (and lower-left worm screw and left axis of guide) can be moved to the left vertically, right sliding sleeve (and bottom right worm screw and right axis of guide) can move right vertically, so driven wheel (left driven wheel now, right driven wheel) motionless, left sliding sleeve (and lower-left worm screw and left axis of guide) is moved to the left and rotates, right sliding sleeve (and bottom right worm screw and right axis of guide) moves right and rotates, until the left part 451 of bottom left worm screw 45 and the right part 481 of left support abutment 48 contact, and till the right part 551 of bottom right worm screw 55 and the left part 581 of right support abutment 58 contact.After the left part of bottom left worm screw 45 contacts with the right part of left support abutment 48, and after the right part of bottom right worm screw 55 contacts with the left part of right support abutment 58, because can not moving axially, lower worm screw can only rotate, so left driven wheel just starts to rotate counterclockwise and to right translation, right driven wheel just starts to clockwise rotate and to left, thereby drive left bed board to rotate counterclockwise and to right translation, right bedboard clockwise rotates and to left.When left and right bed board turn to and crosses vertical position from leg-of-mutton guard mode, both made motor power-off speed reducer output shaft not turn, left and right bed board still can lean on the gravity of self to be rotated further (until left and right bed board rotates level).When left and right bed board turn to and crosses vertical position from leg-of-mutton guard mode; because driven wheel (left driven wheel, right driven wheel) in axial direction changes to lower worm screw (lower-left worm screw, bottom right worm screw) thrust; cause left sliding sleeve (and lower-left worm screw and left axis of guide) to move right; right sliding sleeve (and bottom right worm screw and right axis of guide) is moved to the left; like this; just separate the right part of the left part of bottom left worm screw 45 and left support abutment 48, and also separate the left part of the right part of bottom right worm screw 55 and right support abutment 58.
No matter be that left and right bed board forms the process of leg-of-mutton guard mode from being positioned at horizontal (normally) state variation of horizontal level to left and right bed board, or from guard mode, change to the process of horizontal (normally) state, when left and right bed board naturally rotates (and translation) under Action of Gravity Field, owing to thering is the effect of two synchronous fuel tanks, synchronous all the time while making the both sides translation to the left and right of left and right bed board, just synchronize rotation with the left driven wheel of worm engaging under left and right, right driven wheel, so left and right bed board overturns, translation is all synchronous; And owing to having the restriction of synchronous fuel tank, the speed of left and right bed board both sides translation to the left and right (the lower worm screw in left and right moves axially to the left and right) is basicly stable and speed is slower; Because worm shaft under left and right is subject to the restriction of synchronous fuel tank and slower to translational speed, just slower with the rotating speed of the left driven wheel of worm engaging under left and right, right driven wheel, so the velocity of rotation of left and right bed board can be not too fast, prevent that people or other thing are sandwiched between the bed board of left and right and are crushed; In addition, both made people or other thing be sandwiched between the bed board of left and right, because left and right bed board is to rotate (not being the driving that relies on motor) because of gravity, add that synchronous fuel tank can share enough large gravity of left and right bed board, so the power that the people between the bed board of left and right or other thing left and right are subject to is less, guarantor can not crushed, and has improved safety coefficient.
