The shockproof bed comprises the bed frame, two split type bedplates, namely a left bedplate and a right bedplate, a rollover driving mechanism and the synchronization mechanism, wherein the rollover driving mechanism makes the left bedplate and the right bedplate rotate towards opposite directions and makes the human body positioned on the left bedplate and the right bedplate fall into the bed frame; after the human body falls into the bed frame, the left bedplate and the right bedplate cover the position above the human body under the driving of the rollover driving mechanism; the left bedplate and the right bedplate are connected with a translation driving mechanism for driving the left bedplate and the right bedplate to move towards the left side and the right side respectively; and the synchronization mechanism makes the left bedplate and the right bedplate move towards the left side and the right side.
Description
Technical field
The present invention relates to a kind of shockproof bed, specifically, is a kind of shockproof bed with lazy-tongs.
Background technology
One Chinese patent application CN101874689A discloses a kind of shockproof bed; Comprise bedstead; On bedstead, be provided with two along the bedstead long axis and the bed board axle that can rotate; On every bed board axle, be fixed with a bed board respectively; Be provided with between described bedstead and the bed board and can make two bed boards rotate and make the human body that is positioned on the bed board fall into the upset driving mechanism (being the actuating unit described in its file) of bedstead towards rightabout; And described bed board can block above human body under the upset driving mechanism drives after in human body falls into bedstead, and described upset driving mechanism is connected with control circuit, is being connected with pressure sensor and the seismic sensor that is arranged on the bedstead on the control circuit.When earthquake takes place when; Pressure sensor is with after seismic sensor detects relevant signal; Make the upset driving mechanism move through control circuit; Drive two bed boards and rotate and make the human body that is positioned on the bed board fall into bedstead, and make and drive down at the upset driving mechanism by two bed boards the firm triangle of formation blocks above human body towards rightabout.
But the problem of this shockproof bed is; The upset driving mechanism can only drive two bed boards and rotate with the bed board axle; The 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 can cause extruding from being fixed on to fall between two bed boards on two bed board axles; Two, two bed boards block the top in human body after the bed board axle rotates, the space that holds human body in the bedstead is less.
Also there is the problem how two bed boards rotate synchronously in it under the drive of upset driving mechanism in addition.Because; If both are asynchronous, two bed boards are when blocking above human body, and the lateral edge portion of two bed boards just may not contact; Thereby can not form firm triangle; When weight fell to two bed boards, two bed boards might be shifted, and can not protect the human body that is positioned at its underpart.
Summary of the invention
The purpose of this invention is to provide a kind ofly when can drive two bed boards and rotate, make bed board,, prevent when falling by two bed boards extruding to increase human body from the space that falls between two bed boards to the synchronous translation in the both sides of bedstead; Increase the shockproof bed with lazy-tongs in the space that holds human body in the bedstead simultaneously.
Originally have the shockproof bed of lazy-tongs, comprise bedstead, two split type left and right sides bed boards; Can make two left and right sides bed boards rotate and make the human body that is positioned on the bed board of the left and right sides fall into the upset driving mechanism of bedstead towards rightabout; And described left and right sides bed board can block above human body under the upset driving mechanism drives after in human body falls into bedstead; Left and right sides bed board also with drive its respectively to the left and right the translational drive mechanism of two side shiftings link to each other, it also comprises makes the left and right sides bed board synchronization-moving lazy-tongs in both sides to the left and right.
Beneficial effect of the present invention: this shockproof bed is owing to possess upset driving mechanism, translational drive mechanism and lazy-tongs simultaneously; The upset driving mechanism drives two left and right sides bed boards and rotates towards rightabout; And translational drive mechanism can drive left and right sides bed board two side shiftings to the left and right respectively, and lazy-tongs can make the left and right sides bed board same moved further in both sides to the left and right, like this; Because left bed board is moved to the left; And the same to the right moved further of right bedboard, the distance between two bed boards is bigger, and human body falls Shi Buhui from two bed boards and is pushed by two bed boards; When blocking the top in human body after left and right sides bed board rotates, the space in the bedstead of the bottom between the bed board of the left and right sides will increase; Lazy-tongs have guaranteed the same moved further of left and right sides bed board, thereby are that two bed boards are formed triangle assurance is provided when blocking above human body.
Make left and right sides bed board can realize rotating, can realize again that synchronous translation realizes than being easier to, fairly simple a kind of structure is, translational drive mechanism comprises left and right sides bed board axle, left and right sides slide block, two translation oil cylinders or cylinder; Left and right sides bed board is fixedly linked with left and right sides bed board axle respectively, and left and right sides bed board axle rotates respectively and is arranged on the left and right sides slide block that can slide to the bedstead both sides, left and right sides slide block respectively with drive its translation oil cylinder that horizontally slips or cylinder and link to each other; Be used to drive left and right sides bed board axle and left and right sides slide block be set with respect to the upset driving mechanism that left and right sides slide block rotates; Two translation oil cylinders or air cylinder structure are identical; The rod chamber of two translation oil cylinders or cylinder communicates through pipeline, and the rodless cavity of two translation oil cylinders or cylinder communicates through pipeline; Said two translation oil cylinders or cylinder are said lazy-tongs.
Certainly, if unite two into one upset driving mechanism and translational drive mechanism, can simplified structure; For this reason; Above-mentioned shockproof bed, it also comprises the actuating unit that drives bed board upset and translation, this actuating unit be the upset driving mechanism also be translational drive mechanism; This actuating unit comprises the left and right sides bed board axle that is fixedly linked respectively with left and right sides bed board; Left and right sides bed board axle is slidingly arranged in respectively in the left and right sides chute on the bedstead, and the end of left and right sides bed board axle is provided with left and right sides driven wheel, and up and down two piece left worm screws parallel with left chute mesh with the top and the bottom of left side driving worm gear respectively; Up and down two piece right worm screws parallel with right rail mesh with the top and the bottom of right side driving worm gear respectively; Going up left worm screw and last right worm screw is fixed on the bedstead; Left worm screw links to each other with left sliding sleeve down; Left side sliding sleeve links to each other through the left sliding pair that axially slides mutually with the output shaft of left drive unit; Right worm screw links to each other with right sliding sleeve down; Right sliding sleeve links to each other through the right sliding pair that axially slides mutually with the output shaft of right drive unit; Said lazy-tongs comprise about two two synchronous fuel tanks or cylinder; The piston rod of a left side synchronous fuel tank or cylinder and left sliding sleeve or down left worm screw link to each other, the piston rod of right synchronous fuel tank or cylinder and right sliding sleeve or under right worm screw link to each other; The structure of left and right sides synchronous fuel tank or cylinder is identical; The rod chamber of left and right sides synchronous fuel tank or cylinder communicates through pipeline, and the rodless cavity of left and right sides synchronous fuel tank or cylinder communicates through pipeline.
When left drive unit action, left drive unit output shaft rotates, and drives left sliding sleeve and rotates, and following left worm screw is promptly rotated.And go up that left worm screw is fixed on the bedstead is motionless, rolls when the left driven wheel that therefore all meshes with left worm screw and last left worm screw down can only rotate and along last left worm screw.Left side driven wheel rotates, and then the left bed board axle rotates, and drives left bed board and rotates; Left side driven wheel rolls along last left worm screw, has just realized the translation to the bedstead left side of left bed board axle.That is to say that the left bed board limit is rotated, move to the left on the limit.Contact with the left end of left chute up to the left bed board axle, the left bed board axle promptly stops the translation to the bedstead left side.In like manner, when right drive unit action, right drive unit output shaft rotates, and drives right sliding sleeve and rotates, and following right worm screw is promptly rotated.And go up that right worm screw is fixed on the bedstead is motionless, rolls when the right driven wheel that therefore all meshes with right worm screw and last right worm screw down can only rotate and along last right worm screw.Right driven wheel rotates, and then the right bedboard axle rotates, and drives right bedboard and rotates; Right driven wheel rolls along last right worm screw, has just realized the translation to the bedstead right side of right bedboard axle.That is to say that the right bedboard limit is rotated, move to the right on the limit.Contact with the right-hand end of right rail up to the right bedboard axle, the right bedboard axle promptly stops the translation to the bedstead right side.At this moment left bed board and right bedboard form triangle, to the human body formation protection of bedstead.Because left bed board translation to the left, right bedboard is translation to the right, makes the interior space of bedstead of the bottom between left bed board and the right bedboard increase.Make left and right sides bed board rotate synchronously through synchronous fuel tank or cylinder, simultaneously reduced also that bed board is clamped human body and the possibility that injures human body.
Above-mentioned shockproof bed, following left worm screw links to each other with left sliding sleeve; Left side sliding sleeve is continuous through the left sliding pair of axially slide mutually (but circumferentially can not relatively rotate) with the output shaft of left drive unit; Right worm screw links to each other with right sliding sleeve down; Right sliding sleeve is continuous through the right sliding pair of axially slide mutually (but circumferentially can not relatively rotate) with the output shaft of right drive unit; It also comprises the control circuit that is used to control left drive unit and right drive unit, when left and right sides bed board turn to when crossing vertical position, under the control of the control circuit of left drive unit and right drive unit, stops action.When left and right sides bed board turn to when crossing vertical position; Left and right sides bed board also rotates under the drive of left drive unit and right drive unit; If human body is clamped between the bed board of the left and right sides or is clamped between a left side (right side) bed board and the bedstead, this people's danger may occur crushing.Generation for fear of this situation; So should cut off the power of left drive unit and right drive unit, make it stop action, and let left and right sides bed board under the gravity effect, rotate (and translation) naturally; Like this; The someone was sandwiched between the bed board of the left and right sides perhaps has been sandwiched between a left side (right side) bed board and the bedstead, because (power is cut off) pressure is less, thereby it is injured to reduce human body; The people also can firmly push bed board open, to reach the effect of protection human body, reduces the injured possibility of human body.Because left and right sides bed board is when rotating; Left and right sides driven wheel must rotate average moving; Therefore, need to link to each other through sliding pair (left sliding pair, right sliding pair) with the output shaft of drive unit (left drive unit, right drive unit) through sliding sleeve (left sliding sleeve, right sliding sleeve).Like this, when the output shaft of drive unit rotates, can drive sliding sleeve by sliding pair and rotate, thereby drive worm screw (lower-left worm screw, bottom right worm screw) rotation down, realize the rotation and the translation of left and right sides driven wheel.When turning to, left and right sides bed board crosses vertical position; The power of drive unit is cut off; When its output shaft does not rotate; Left and right sides bed board rotates under the gravity effect naturally, drives left and right sides driven wheel and rotates and translation, and following worm screw (left side is worm screw, bottom right worm screw down) and sliding sleeve (left sliding sleeve, right sliding sleeve) slide with respect to the output shaft of drive unit (left drive unit, right drive unit) vertically.When left and right sides bed board rotated (and translation) naturally under the gravity effect, owing to have the effect of two synchronous fuel tanks or cylinder, the velocity of rotation of left and right sides bed board can be not too fast, further increased the safety coefficient that prevents to crush the people.
Above-mentioned shockproof bed; It also comprises and is used to limit down left worm screw or the left sliding sleeve left support abutment that moves axially distance with respect to left drive unit output shaft, also comprises being used to limit down right worm screw or the right sliding sleeve right support abutment that moves axially distance with respect to right drive unit output shaft.

The left end of left worm screw 45 links to each other with the left axis of guide 47 down, and right-hand member links to each other with left sliding sleeve 46.The left side axis of guide 47 is slidingly arranged in the left support abutment 48 that is fixed on the bedstead; Left support abutment plays guiding, supporting role to the left axis of guide; Also following left worm screw 45 moved axially position-limiting action (after left instantly worm screw 45 was moved to the left certain distance, its left part 451 contacted with left support abutment right part 481 and can not be moved to the left).Left side sliding sleeve 46 is continuous through the spline pair of axially slide mutually (but circumferentially can not relatively rotate) with the output shaft 200 of reductor 400.
The right-hand member of right worm screw 55 links to each other with the right axis of guide 57 down, and left end links to each other with right sliding sleeve 56.The right axis of guide 57 is slidingly arranged in the right support abutment 58 that is fixed on the bedstead; Right support abutment plays guiding, supports the right axis of guide; Also following right worm screw 55 moved axially position-limiting action (right instantly worm screw 55 moves right behind the certain distance, and its right part 551 contacts with right support abutment left part 581 and can not move right).Right sliding sleeve 56 is continuous through the spline pair of axially slide mutually (but circumferentially can not relatively rotate) with the output shaft 200 of reductor.
The output shaft 200 of go up left worm screw 44, down left worm screw 45, left chute 41, going up right worm screw 54, down 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 is coaxial.
Go up left worm screw 44, left worm screw 45 drives the top and the bottom engagement of worm gear 42 respectively with a left side down; Go up right worm screw 54, down right worm screw 55 and the right top and the bottom engagement that drives worm gear 52.
The piston rod 49 of left side synchronous fuel tank 82 links to each other with the left axis of guide 47 through a rebound 71, and the piston rod 59 of right synchronous fuel tank 92 links to each other with the right axis of guide 57.Referring to Fig. 5, the structure of left and right sides synchronous fuel tank is identical; The rod chamber of left and right sides synchronous fuel tank communicates through pipeline 93, and the rodless cavity of left and right sides synchronous fuel tank communicates through pipeline 83.
The axial direction of the left axis of guide 47 is provided with the left lateral journey switch that is fixed on the bedstead, and the axial direction of the right axis of guide 57 is provided with the right lateral journey switch that is fixed on the bedstead.
The left worm screw 81 in back is fixed on the tailstock plate 13 with the right worm screw 91 in back.Left side driven gear 43 and left worm screw 81 engagements in back, right driven gear 53 and right worm screw 91 engagements in back.
Motor 300 links to each other with the power shaft of reductor, and the control circuit that is used to control motor is received in the output of left lateral journey switch and right lateral journey switch.
When normal condition, form one flat plates and be positioned on the bedstead referring to Fig. 3,4, two left and right sides bed board butt joints.When the relevant sensor in the control circuit detects the earthquake generation, motor action, the output shaft of reductor rotates, and drives sliding sleeve (left sliding sleeve, right sliding sleeve) and rotates, and following worm screw (worm screw, bottom right worm screw under the left side) is promptly rotated.And go up that worm screw (upper left worm screw, upper right worm screw) is fixed on the bedstead is motionless; Therefore the driven wheel (left driven wheel, right driven wheel) that all meshes with following worm screw and last worm screw is when can only rotate and along last worm screw rolling (left driven wheel rolls to the left, right driven wheel rolls to the right); Promptly; Left side worm screw (and left sliding sleeve and left axis of guide) down is moved to the left when rotating vertically, and bottom right worm screw (and right sliding sleeve and right axis of guide) moves right when rotating vertically.Like this, the left bed board axle rotate and along left chute to left, drive that left bed board rotates and to left; The right bedboard axle rotate and along right rail to right translation, drive that right bedboard rotates and to right translation.
When left and right sides bed board before horizontal (normally) state turnover to the vertical position that is positioned at horizontal level; Because the gravity effect of left bed board; Left side driven wheel is to the generation thrust to the right of worm screw under the left side; Make left worm screw down and left sliding sleeve be pressed on all the time on the speed reducer output shaft to the right, left side worm screw (and left sliding sleeve and left axis of guide) down can not move axially; In like manner; Because the gravity effect of right bedboard; Right driven wheel makes bottom right worm screw and right sliding sleeve be pressed on all the time on the speed reducer output shaft left to the generation thrust left of bottom right worm screw, and bottom right worm screw (and right sliding sleeve and right axis of guide) can not moved vertically yet.
Certainly; When left and right sides bed board from horizontal (normally) state turnover that is positioned at horizontal level after cross vertical position; Because the gravity effect of left and right sides bed board; Left side driven wheel is to the generation thrust left of worm screw under the left side, and right driven wheel is to the generation thrust to the right of bottom right worm screw, because sliding sleeve (left sliding sleeve, right sliding sleeve) can axially slide with respect to speed reducer output shaft relatively; Thereby make the left axis of guide (following left worm screw, left sliding sleeve) be moved to the left, the right axis of guide (following right worm screw, right sliding sleeve) moves right.
When left and right sides bed board from horizontal (normally) state turnover that is positioned at horizontal level after cross vertical position; The left axis of guide that is moved to the left is vertically run into left lateral journey switch; Perhaps, run into right lateral journey switch by the right axis of guide that moves left vertically, control circuit control motor stops action.When the power of motor is cut off; Its speed reducer output shaft does not rotate; But because left and right sides bed board has turn to and has crossed vertical position; At this moment left bed board can clockwise rotate because of gravity effect still continuation, and right bedboard can rotate counterclockwise because of gravity effect still continuation, so left and right sides bed board axle still can rotate.Left and right sides bed board axle rotates; Left and right sides driven wheel must rotate; And inevitable translation when rotating of left and right sides driven wheel (the left bed board axle rotates and to left; The right bedboard axle rotate and to right translation); Like this, a left side down worm screw (and left sliding sleeve and left axis of guide) is being rotated and under the drive of the left driven wheel of left, is being slided (speed reducer output shaft does not rotate) left vertically with respect to speed reducer output shaft, 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).Contact with the left end of left chute up to the left bed board axle, the 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 last end in contact of left and right sides bed board forms firm triangle (referring to Fig. 1,2).Left and right sides bed board from horizontal (normally) state turnover that is positioned at horizontal level after cross vertical position; When human body was clamped, because reductor does not rotate, pressure was little; Thereby it is injured to reduce human body; And the people can firmly push bed board open, and human body can get in the 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 used to detect the weight of whole bed.On bed, sleeping has man-hour, pressure sensor to detect the pressure change greatly, and its output signal is to control circuit, and motor just possibly move.When having no talent on the bed, the pressure that pressure sensor detects does not increase, and has both made seismic sensor detect vibration signal, and control circuit can not send signal yet and make motor action.More smooth in the process of upset and translation for left and right sides bed board, left driven gear 43 meshes with the left worm screw 81 in back, right driven gear 53 and right worm screw 91 engagements in back.In driven wheel rotation and translation process, driven gear (left driven gear, right driven gear) is with respect to back worm screw (the left worm screw in back, the right worm screw in back) rotation and translation.
Bed board forms the process of leg-of-mutton guard mode to horizontal (normally) state variation that shockproof bed recited above is arranged in horizontal level from its left and right sides bed board to the left and right sides; The left part 451 of left worm screw 45 does not contact with the right part 481 of left support abutment 48 all the time down, and the right part 551 of following right worm screw 55 does not contact with the left part 581 of right support abutment 58 all the time.Return to then difference of horizontal (normally) state from the guard mode variation, brief description changes to the process of horizontal (normally) state from guard mode.
Motor gets electric rotation, and the output shaft of reductor rotates, and drives sliding sleeve (left sliding sleeve, right sliding sleeve) and rotates, and following worm screw (left side is worm screw, bottom right worm screw down) is promptly rotated.Because left sliding sleeve (and left worm screw and left axis of guide down) 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 this moment (left driven wheel, right driven wheel) is motionless; Left side sliding sleeve (and left worm screw and left axis of guide down) is moved to the left and rotates; Right sliding sleeve (and bottom right worm screw and right axis of guide) moves right and rotates, and contact with the right part 481 of left support abutment 48 up to the left part 451 of left worm screw 45 down, and the right part 551 of right worm screw 55 is with till the left part 581 of right support abutment 58 contacts under reaching.Down the left part of left worm screw 45 is with after the right part of left support abutment 48 contacts; And down the right part of right worm screw 55 with after the left part of right support abutment 58 contacts; Because of following worm screw can not move axially and can only rotate, so left driven wheel just begins to rotate counterclockwise and to right translation, right driven wheel just begins to clockwise rotate and to left; Thereby drive that left bed board rotates counterclockwise and to right translation, right bedboard clockwise rotates and to left.When left and right sides bed board turn to from leg-of-mutton guard mode cross vertical position after, motor outage speed reducer output shaft was not changeed, left and right sides bed board still can lean on the gravity of self to be rotated further (till left and right sides bed board rotates level).When left and right sides bed board turn to from leg-of-mutton guard mode cross vertical position after; Because of driven wheel (left driven wheel, right driven wheel) in axial direction changes to following worm screw (left side is worm screw, bottom right worm screw down) thrust; Cause left sliding sleeve (and left worm screw and left axis of guide down) 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 left part of following left worm screw 45 and left support abutment 48, and also separate the left part of right part of following right worm screw 55 and right support abutment 58.
Bed board forms the process of leg-of-mutton guard mode to the left and right sides from horizontal (normally) state variation that is positioned at horizontal level no matter be left and right sides bed board; Still change to the process of horizontal (normally) state from guard mode; When left and right sides bed board rotates (and translation) naturally under the gravity effect; Owing to have the effect of two synchronous fuel tanks; Synchronous all the time when making the both sides translation to the left and right of left and right sides bed board, with about down left driven wheel, the right driven wheel of worm engaging just rotate synchronously, so the upset of left and right sides bed board, translation all are synchronous; And owing to have the restriction of synchronous fuel tank, the speed of left and right sides bed board both sides translation to the left and right (worm screw moves axially to the left and right under promptly) is basicly stable and speed is slower; Since about down worm shaft receive the restriction of synchronous fuel tank and slower to translational speed; With about down the rotating speed of left driven wheel, the right driven wheel of worm engaging is just slower; So the velocity of rotation of left and right sides bed board can be not too fast, prevent that people or other thing are sandwiched between the bed board of the left and right sides and crushed; In addition; People or other thing were sandwiched between the bed board of the left and right sides; Because left and right sides bed board is because of gravity rotates the driving of motor (be not rely on), add that synchronous fuel tank can share the enough big gravity of left and right sides bed board, so the power that about the people between the bed board of the left and right sides or other thing, receives is less; The guarantor can not crushed, and has improved safety coefficient.
