For the ease of connector 33 and main damper 31, the installation of secondary shock absorber 32 and dismounting, it is preferable that such as Fig. 8, Figure 10 It is shown, connector 33 is divided into the first half-connection part 331 and the second half-connection part 332, the first half-connection part 331 connects with the second half The two ends of fitting 332 are detachably connected by screw.So, the limited ring groove 333 on connector 33 just has the first half-connection part The semi-circular groove in semi-circular groove and the second half-connection part 332 on 331 is combined to form.Limited post 334 on connector 33 by 334 sections of limited post on 334 sections of limited post on first half-connection part 331 and the second half-connection part 332 is combined to form.Secondary vibration damping When device 32 is connected with main damper 31, the positioning ring groove 311 at the middle part of main damper 31, the secondary first end of shock absorber 32 are determined Semi-circular groove in any one of position through hole and two half-connection parts, 334 sections of limited post coordinate, then by two half-connection part buttons It is combined, the most two ends of latter two half-connection part are fastened by screw.Can be with separately by the fastening of two half-connection parts Make the easy accessibility of main damper 31 and secondary shock absorber 32.
Wherein, there be another kind of connected mode at the two ends of the first half-connection part 331 and the second half-connection part 332, specifically, First half-connection part 331 and the one end of the second half-connection part 332 can be hinged, and the other end is fixedly connected by screw, wherein the first half The half-connection part 332 of connector 331 and second can be rotated around pin joint.The connection behaviour of the scheme being all fastenedly connected with screw with two ends Compare as process, the difference of this connection scheme is, before proceeding the first half-connection part 331 and the second half-connection part 332 Need to open certain angle with facilitate main damper 31, the secondary location structure of shock absorber 32 easily with one of half-connection part The cooperation of position limiting structure, is then fastened two half-connection parts with the mode of rotation, the half-connection part snapped together at two The other end fastened with screw.Connection scheme only one end screw of this two half-connection parts is fastenedly connected and can reduce master The time of the dismounting of shock absorber 31 and secondary shock absorber 32.
In order that the left rotation and right rotation that secondary shock absorber 32 preferably limits cartridge module 2 of doing washing in the course of the work swings, preferably The plane that the axis of main damper 31 and secondary shock absorber 32 is formed is vertical with the axis of bottom washing drum 21.So, do washing The active force for a little producing to secondary shock absorber 32, Jiu Huiyan are connected thereto by secondary shock absorber 32 when the left rotation and right rotation of cartridge module 2 swings The axis for secondary shock absorber 32 passes to main damper 31 by connector 33, and the secondary shock absorber 31 of such main damper 31 pairs is formed One effectively supports, and is conducive to the balance and stability of laundry cartridge module 2.
In order to cartridge module 2 of doing washing stress balance with it is stable, it is preferable that as shown in Figure 4, Figure 5, multiple combination vibration dampings Device 3 is symmetricly set in the both sides of bottom washing drum 21.The quantity of combination shock absorber 3 is even number, such as four, six etc., is combined The quantity of shock absorber 3 should not be arranged too much, on the one hand due to the limited length of bottom washing drum 21, do not placed too many combination and subtracted Shake device 3;On the other hand, arranging too many combination shock absorber 3 can increase the gross weight of washing machine, and also need to be done washing in bottom The both sides of cylinder 21 arrange multiple tie points so as to which manufacture and assembling process become loaded down with trivial details.Therefore, it is flat in satisfaction laundry cartridge module 2 On the premise of weighing apparatus and stability, the quantity preferably four of shock absorber 3 is combined.
Referring to Fig. 6, the angle that main damper 31 and secondary shock absorber 32 are formed should be controlled between 10 °~60 °.Angle It is that size is mainly determined by the installation site of main damper 31 and the secondary two ends of shock absorber 32 and directly influence and combine shock absorber 3 Effectiveness in vibration suppression, if angle is too small, the restriction effect of the rotary oscillation of so secondary 32 pairs of laundry left and right directions of cartridge module 2 of shock absorber Can be bad;If angle is excessive, the left rotation and right rotation of cartridge module 2 of doing washing is easy to brokenly when swinging to the active force that secondary shock absorber 32 is produced Bad connector 33, the balance and stability of the cartridge module 2 that is unfavorable for entirely doing washing.Therefore, in order that laundry cartridge module 2 balance with surely It is fixed, allow secondary shock absorber 32 preferably to limit the rotary oscillation on the laundry left and right directions of cartridge module 2, its corner dimension is preferably at 10 ° Between~60 °.
It is varied from due to combining the stress of shock absorber 3 in three washing machine courses of work, is subjected to certain lateral Radial load, therefore the material of main damper 31 and secondary shock absorber 32 is preferably made up of hard metal material, such as high-carbon steel, titanium Alloy etc..
With reference to Fig. 4, Fig. 5 and Fig. 6, the second end of secondary shock absorber 32 is higher than the second end of main damper 31.Due to washing drum The center of gravity of component 2 is on the upper side, if the second end of secondary shock absorber 32 can make combination shock absorber 3 less than the second end of main damper 31 Excessively on the lower side with the position of two tie points of bottom washing drum 21, this supporting way is unfavorable for the balance of laundry cartridge module 2 With it is stable.By the second end of secondary shock absorber 32 higher than the second end of main damper 31, so support and be not only advantageous to washing drum group The balance of part 2, and the left rotation and right rotation that secondary shock absorber 32 preferably limits laundry cartridge module 2 is swung, and then can subtract The little laundry top local vibration of cartridge module 2.
In order to further reduce the vibration of cartridge module 2 of doing washing in the course of work, it is preferable that as shown in figure 4, hanging the one of spring 4 End is connected on bottom washing drum 21, and the other end is connected to the middle part of casing 1.So design when cartridge module 2 of doing washing vibrates, Coordinate several combination shock absorbers 3 of laundry cartridge module 2 bottom, hanging spring 4 can be to each side of laundry cartridge module 2 by elastic telescopic To vibration play a part of further restriction.
Referring to Fig. 3 and Fig. 4, due to three washing machine upper spaces it is limited, if the one end for hanging spring 4 is connected to top and washes Certain space can be taken on clothing cylinder 22, the capacity that can make top washing drum 22 diminishes, therefore extension spring 4 one end is connected to bottom and washes On clothing cylinder 21, can indirectly increase the capacity of top washing drum 22.The other end for hanging spring 4 is connected with the middle part of casing 1, so Uniform force on casing 1 can be made, is conducive to the balance and stability of casing 1.
Wherein, hanging the number of spring 4 should not be arranged excessively, and arranging excessive extension spring 4 needs in bottom washing drum 21 and casing 1 It is upper that multiple tie points are set, can so make the manufacture of three washing machines and assemble loaded down with trivial details, meanwhile, the number for hanging spring 4 is also unsuitable Very little, the balance of laundry cartridge module 2 is unfavorable for very little, therefore, in the case where the requirement of vibration damping and stress balance is met, hang the number of spring 4 Amount preferably four.
Referring to Fig. 3 and Fig. 4, in order to balance the weight of the laundry fore-and-aft direction of cartridge module 2, laundry cartridge module 2 is further reduced Center of gravity, reduce the local vibration above it, balancing weight 214 is preferably connected with below the nozzle of bottom washing drum 21.Due to The portion's installation behind of motor 62 of the rotation of bottom washing drum 21 is driven, therefore balancing weight is set below the nozzle of bottom washing drum 21 214 are conducive to the fore-and-aft direction weight balancing of cartridge module 2 of entirely doing washing.Due to balancing weight 214 install more on the lower, be more conducive to drop The center of gravity of low whole laundry cartridge module 2, therefore balancing weight 214 is arranged on into the lower section of the nozzle of bottom washing drum 21, it is so favourable In the local vibration for reducing the top of laundry cartridge module 2.
Wherein, can be by being rigidly connected between two top washing drums 22 and bottom washing drum 21, it is also possible to by soft Property connection, but, due to using easily transmission vibration between top washing drum 22 and bottom washing drum 21 when being rigidly connected, when upper When portion's washing drum 22 and the close vibration frequency of bottom washing drum 21, laundry cartridge module 2 can resonate, and then easily produce very big Vibration noise.It is therefore preferable that using scheme as shown in Figure 4, Figure 5, top washing drum 22 and bottom washing drum 21 are passed through Coupling assembly 5 connects, and as shown in Figure 11, Figure 12 and Figure 13, coupling assembly 5 includes vibration-reducing connecting part 51, vibration-reducing connecting part 51 At least a portion is fabricated from a flexible material.
Due to being connected by vibration-reducing connecting part 51 between top washing drum 22 and bottom washing drum 21, and vibration-reducing connecting part 51 at least a portion is fabricated from a flexible material, and because flexible material has certain damping, when flexible material forced vibration When, it produces violent interior friction, so as to produce reaction force, the kinetic energy of the generation of forced vibration is converted into heat energy, can The amplitude of its forced vibration is significantly reduced in a short period of time, reaches the purpose of vibration damping, vibration isolation, therefore, in laundry Machine top washing drum 22 and bottom washing drum 21 work simultaneously when, vibration-reducing connecting part 51 can weaken top washing drum 22 and wash with bottom Vibration transmission between clothing cylinder 21, reduces the noise that vibration is produced.Further, since top washing drum 22 and bottom washing drum 21 Between vibration transmission separated by vibration-reducing connecting part 51, so make laundry cartridge module 2 easily avoid resonance region, top can be reduced and washed There is the probability of vibration coupling with bottom washing drum 21 in clothing cylinder 22.
It should be noted that:Vibration-reducing connecting part 51 is not limited to apply three washing machines there is two top washing drums 22 In, it is also possible to apply in many washing machines for having at least one top washing drum 22, the number of its middle and upper part washing drum 22 can Think 1,3 etc., be not limited thereto.
Wherein, vibration-reducing connecting part 51 can also all be fabricated from a flexible material, flexible material can for plastics, rubber etc., Because the material for being connected position between top washing drum 22 and bottom washing drum 21 needs certain intensity, it belongs to rigidity Material, has very big difference with the property of flexible material, wants to be reliably connected together flexible material and rigid material, needs They to be fixed together by certain technique, can so cause the inconvenience dismantled between them.
Therefore, for convenience vibration-reducing connecting part 51 and top washing drum 22, bottom washing drum 21 being vertically connected with and dismantling, Preferably, vibration-reducing connecting part 51 includes two be rigidly connected portions and flexible anti-vibration portion, and flexible anti-vibration portion is fixed on two rigidity and connects Between socket part, the portion that is rigidly connected on the upside of flexible anti-vibration portion is connected with top washing drum 22, positioned at flexible anti-vibration subordinate side The portion that is rigidly connected be connected with bottom washing drum 21.Because flexible anti-vibration portion is fixed with one with two portions of being rigidly connected, this When sample is installed with dismantling, it is only necessary to be connected two portions that are rigidly connected with upper and lower top washing drum 22 and bottom washing drum 21 Position connects and dismounting, very convenient.Simultaneously as top washing drum 22 is connected position with bottom washing drum 21 It is rigid material, rigid material is connected with certain bonding strength with rigid material, also ensure that the reliability of connection.
Further, compare with other materials, the rigidity of metal material is relatively good, therefore, the rigidity of vibration-reducing connecting part 51 Connecting portion preferred metal materials are made, for example, carbon steel, copper etc.;Compare with other flexible materials, rubber has wear-resisting well Property, very high elasticity, be for the comparatively ideal material of vibration damping, vibration isolation, therefore, the material in the flexible anti-vibration portion of vibration-reducing connecting part 51 Expect then preferred rubber material.
Wherein, the be rigidly connected concrete structure of portion and flexible joint of two of vibration-reducing connecting part 51 has various, in order to enter The bonding strength and security of the guarantee vibration-reducing connecting part 51 of one step, Figure 11, Figure 12 show a kind of alternative construction, specifically, The portion of being rigidly connected on the upside of flexible anti-vibration portion is connection lid 511, is company positioned at the portion of being rigidly connected of flexible anti-vibration subordinate side Acting flange 513, flexible anti-vibration portion is the rubber layer 512 being filled between connection lid 511 and adpting flange 513, connects lid 511 Middle part offers screwed hole, and connection lid 511 is connected by screwed hole with top washing drum 22, and the periphery of adpting flange 513 is opened up There is installing hole, adpting flange 513 is connected by installing hole with bottom washing drum 21.Wash because vibration-reducing connecting part 51 not only will bear The weight of clothing machine top washing drum 22 and clothes and water, still suffers from addition the vibration in the course of work, of long duration, and vibration damping connects Fitting 51 is susceptible to fatigue failure, and it belongs to attrition component.For the ease of keeping in repair and changing, connection lid 511 by screwed hole with Top washing drum 22 connects, and adpting flange 513 is connected by installing hole with bottom washing drum 21, and such vibration-reducing connecting part 51 can be with Easily remove and install.In addition connection lid 511 wraps up rubber layer 512 inside it, can so protect rubber layer 512 to avoid Be exposed in the environment of surrounding and occur it is aging so as to affect its performance, and connect lid 511, adpting flange 513 and between Rubber layer 512 has larger contact area, being capable of preferably vibration damping and vibration isolation.
For ease of connecting the processing of the upper screwed hole of lid 511, as shown in Figure 11, Figure 12, preferably set at the middle part of connection lid 511 The connecting shaft 514 for extending downwardly is put, screwed hole is opened in connecting shaft 514.If connecting shaft 514 and connection lid 511 are one The processing of so screwed hole be typically placed on part comparison operation processing rearward, plus man-hour requirement is installed workpiece to lathe Fixture on, due to connect lid 511 be easily deformed when being installed, Integral design be unfavorable for middle part screwed hole processing, therefore, Screw thread is first processed in connecting shaft 514, the middle part of connection lid 511 is then positioned in again and is fixedly connected, so can be made The processing of screwed hole is easier, and then reduces the processing cost of connection lid 511.
Wherein, the portion that is rigidly connected of vibration-reducing connecting part 51 is preferably fixed with one with flexible anti-vibration portion by sulfuration process. Specifically, as shown in figure 12, the connecting shaft 514, adpting flange at the connection lid 511 of shock absorber connector and the middle part of connection lid 511 513 are fixed with one with rubber layer 512 by sulfuration process.Due to shock absorber connector Main Function be in order to vibration damping every Shake, also there is in addition certain bonding strength and connect lid 511 with rubber layer 512, adpting flange 513 and rubber layer 512 Between relative movement can not occur, therefore, need to be fixed with one between them.Due to rubber layer 512 and the chemistry knot of metal Structure and mechanical performance have huge difference, make them be fixed with one by sulfuration process, can comprehensive rubber layer 512 it is high-elastic Property and metal high intensity, so as to obtain more preferable intensity and durability, while having vibration damping, vibration isolation, the function such as wear-resisting.
Figure 13 show two of vibration-reducing connecting part 51 and is rigidly connected another kind of structure of portion and flexible joint.Specifically Ground, the portion of being rigidly connected on the upside of flexible anti-vibration portion is the ' of the first attachment screw 511, positioned at the rigidity of flexible anti-vibration subordinate side Connecting portion be the ' of the second attachment screw 513, flexible anti-vibration portion be the ' of rubber contiguous block 512, the head of screw of the ' of the first attachment screw 511 It is connected with the ' of rubber contiguous block 512 respectively with the head of screw of the ' of the second attachment screw 513, the screw rod of the ' of the first attachment screw 511 is used for It is connected with top washing drum 22, the screw rod of the ' of the second attachment screw 513 is used to be connected with bottom washing drum 21.
Because the ' of rubber contiguous block 512 directly consolidates with the head of screw of the ' of the first attachment screw 511, the ' of the second attachment screw 513 Even, part used is less, makes the simple structure of vibration-reducing connecting part 51.In addition, the ' of the first attachment screw 511, the ' of the second attachment screw 513 Screw rod be connected with top washing drum 22, bottom washing drum 21 respectively, the dismounting of this connected mode is more convenient, and only needs clockwise Or rotate counterclockwise vibration-reducing connecting part 51 can be achieved with its dismounting.Because the ' of rubber contiguous block 512 not only has high resiliency, have again Have certain rigidity, therefore it both can guarantee that bonding strength, but can vibration damping and vibration isolation, and then top washing drum 22 can be avoided with Portion's washing drum 21 resonates, and reduces vibration noise.
Referring to Fig. 4, Fig. 5, coupling assembly 5 also includes front contiguous block 52 and rear contiguous block 53, wherein, front contiguous block 52 is close The nozzle of bottom washing drum 21 is arranged, and rear contiguous block 53 is arranged near the rear portion motor 211 of bottom washing drum 21.Due on two Portion's washing drum 22 is impeller-type washing drum, and inevitably there is error the integral installation position of two impeller-type washing drums, forward Or rearward all can affect do washing cartridge module 2 anterior-posterior balance, therefore, by the way that front contiguous block 52 and rear contiguous block 53 are configured into difference Weight can make to keep balance before and after top washing drum 22.
In order that two stress balances of top washing drum 22 as shown in Figure 4, Figure 5, preferably connect multiple vibration dampings with stably Part 51 is uniformly distributed between top washing drum 22 and bottom washing drum 21.Wherein, the quantity of vibration-reducing connecting part 51 can be four It is individual, or six etc..The number of vibration-reducing connecting part 51 should not be excessive, and arranging excessive vibration-reducing connecting part 51 needs on top Excessive tie point is set between washing drum 22 and bottom washing drum 21, is that the assembling process of laundry cartridge module 2 becomes loaded down with trivial details.Cause This, on the premise of it ensure that two impeller-type washing drums are balanced, the quantity of vibration-reducing connecting part 51 preferably four.
Wherein, the unfolding mode of upper cover door 61 of three washing machines can be manual, or automatic, due to this Three washing machines arrange two top washing drums 22 in the top of bottom washing drum 21 and two top washing drums are perpendicular for two The impeller-type washing drum of arrangement, in order to ensure the capacity of two top washing drums 22, so its fuselage height is than common Washing machine is high, when clothing is cleaned using two top washing drums 22, because two location comparisons of top washing drum 22 are top, And it is not convenient during such subscriber switch upper cover door 61 for top cover-lifting type, it is therefore preferable that washing on two tops of the correspondence of casing 1 The tube port position of clothing cylinder 22 is hinged with upper cover door 61, and upper cover door 61 is connected with driving means, and driving means can drive upper cover door 61 to exist Rotate between open position and closing position.
Because the tube port position in the two top washing drums 22 of correspondence of casing 1 is hinged with upper cover door 61, and upper cover door 61 connects The driving means that upper cover door 61 can be driven to rotate between the open and the closed positions are connected to, thus can be by controlling to drive Dynamic device makes corresponding action to realize the opening of upper cover door 61 and close, and solve that manual switching station brings is not convenient, The automatization level of washing machine is improve, while also improving the experience of user.
It should be noted that:This driving means that upper cover door 61 can be driven to be opened and closed are not limited to be washed for two tops Clothing cylinder 22 is three washing machines of impeller-type washing drum, it can also be used at least one top washing drum 22 and top washing drum 22 For many washing machines of impeller-type washing drum, wherein, the number of top washing drum 22 is not limited for 1,3 etc..In addition, should Driving means can be additionally used in monotubular pulsator washing machine.
Wherein, open upper cover door 61 has various with the driving means closed, for example, cylinder, hydraulic motor etc..This enforcement In mode, as shown in Figure 15, Figure 21 and Figure 22, driving means include motor 62, and drive shaft and the upper cover door 61 of motor 62 are driven Connection.Compared with cylinder, hydraulic motor, with motor 62 drive make three washing machines structure it is simpler, compact, take up room It is little, it is not necessary to increase air pump, hydraulic pump, pipeline, the control annex such as valve, in addition, the rotation of motor 62 is to use electric drive, with compared with Quickly response speed, ensure that upper cover door 61 is opened in time, closed, not delayed.Additionally, motor 62 passes through motor driving shaft 621 are connected with upper cover door 61, and motor driving shaft 621 is separately designed with rotor, so when motor 62 breaks down When, can easily remove and install.
Further, driving means can be accomplished in several ways the opening and closing of upper cover door 61.Such as driving means can be with It is connected by tie point at upper cover door 61, now, driving means can be by applying to drive to this tie point to upper cover door 61 Power, to drive upper cover door 61 to rotate between the open and the closed positions.Specifically, as shown in figure 15, upper cover door 61 is led to Cross the first hinged set 611 and the second hinged set 612 is hinged with casing 1, the hinged set 611 or the second of motor driving shaft 621 and first Hinged set 612 is connected.It is connected in mode this, the hinged set of the right-hand member of motor driving shaft 621 and the body of upper cover door 61 It is engaged, left end is engaged with the output section of motor 62, is driven using straight drive, it is middle without other transmission devices, therefore, transmission effect Rate is higher, ensure that the output torque of motor 62 is at utmost used for door opening action.
It should be noted that:Torque needed for due to opening upper cover door 61 be not it is very big, as shown in figure 17, motor driving shaft 621 preferably adopt aluminum alloy material, so ensure that part be easily worked, weight it is also less.
In order to reduce enabling or the buckling deformation of door body at closing time, the material of the material preferred high strength of door body, such as aluminium Alloy, engineering plastics etc..Because motor 62 is positioned at the side of upper cover door 61, when upper cover door 61 is opened or closed, motor 62 Output torque first acts on side, transmits torque to opposite side hinge sleeve to realize the overall upset of upper cover door 61 by door body, so goes up Easily there is buckling deformation because of unbalance stress in lid door 61, therefore, upper cover door 61 preferably is made up to resist this of high-strength material Plant buckling deformation.
In order to slow down the closing speed of upper cover door 61, motor damping device is preferably set in motor 62.When upper cover door 61 When rotating to closing position, due to the collective effect of the torque of the self gravitation of upper cover door 61 and motor 62, speed is turned off more next It is faster, therefore, motor damping device can provide reverse resistance to suppress the rotation of motor driving shaft 621 too fast, can reduce The closing speed of upper cover door 61, it is to avoid the too fast damage for causing that collides with casing 1 of upper cover door 61 closing velocity.
In order to further slow down the closing speed of upper cover door 61, close upper cover door 61 soft slow, as shown in Figure 15, Figure 18, It is preferred that being provided with unidirectional damping device 63 in the hinged place of upper cover door 61 and casing 1.Because unidirectional damping device 63 can be at one The resistance of motion is provided on direction, resistance is not then provided in the other directions, therefore, when upper cover door 61 is opened, 62 grams of motor Take the gravity acting of upper cover door 61 to realize that the upset of upper cover door 61 is opened, now, unidirectional damping device 63 does not provide the resistance of motion; When upper cover door 61 is closed, upper cover door 61 can turn off excessive velocities under gravity and the collective effect of the torque of motor 62, now, Motor damping device, unidirectional damping device 63 is coordinated to provide the resistance of motion to slow down the closing velocity of upper cover door 61, it is ensured that Upper cover door 61 is closed soft slow.
In order that the stress balance when closed of upper cover door 61, it is preferable that as shown in figure 15, upper cover door 61 is hinged by first The hinged set 612 of set 611 and second is hinged with casing 1, and the drive shaft of motor 62 is connected with the first hinged set 611, unidirectional damping Device 63 is connected with the second hinged set 612;Or the drive shaft of motor 62 is connected with the second hinged set 612, unidirectional damping device 63 are connected with the first hinged set 611.Because when upper cover door 61 is closed, unidirectional damping device 63 and motor damping device are all provided Resistance slow down the closing velocity of upper cover door 61, therefore, motor 62 and unidirectional damping device 63 be arranged on into upper cover door 61 Both sides, are conducive to the stress balance of upper cover door 61, it is to avoid upper cover door 61 side be subject to resistance and opposite side by caused Buckling deformation.
In addition, driving means can also be connected with upper cover door 61 at least through tie point at two, driving means can be by extremely Tie point applies driving force to upper cover door 61 at few two, to drive upper cover door 61 to rotate between the open and the closed positions. Because driving means are to apply driving force to upper cover door 61 by tie point at least two, upper cover door 61 is subject to when opening The effect of multiple driving forces, the stress of such upper cover door 61 is just than more uniform, it is to avoid what upper cover door 61 occurred because of unbalance stress Buckling deformation.
Wherein, driving means should not be excessive with the tie point of upper cover door 61, if tie point is excessive, these tie points are just not Easily coaxial, driving means are easy for jam occur when upper cover door 61 are opened and closed, and the opening and closing for making upper cover door 61 has some setbacks, drop The low experience of user.Therefore, be avoided that upper cover door 61 occur buckling deformation on the premise of, driving means preferably with upper cover door 61 by tie point connection at two, and can by this at two tie point apply driving force to upper cover door 61.
Further, driving means are not unique to the structure that upper cover door 61 applies driving force by tie point at two.As schemed 21 show driving means passes through a kind of alternative construction that tie point at two applies driving force to upper cover door 61, specifically, motor 62 include motor driving shaft, and motor driving shaft is connected with upper cover door 61, and motor driving shaft includes the first drive shaft 622 and the Two drive shafts 623, the first drive shaft 622 and the second drive shaft 623 are coaxially set and respectively positioned at the both sides of motor, first drives The drive shaft 623 of moving axis 622 and second is connected respectively with upper cover door 61.Because the both sides of motor 62 are provided with two drive shafts simultaneously And the two drive shafts are coaxial, and because two drive shafts are connected respectively with upper cover door 61, so, the output torque of motor 62 It is directly delivered at upper cover door 61 by two drive shafts of the both sides of motor 62, therefore, upper cover door 61 is opening or closing process Middle both sides stress, easily keeps balance, it is to avoid motor 62 is unilateral to drive the warpage of the upper cover door 61 caused by upper cover door 61 to become Shape, and then the requirement to the intensity of upper cover door 61 can be reduced.
Referring to Figure 21 and Figure 22, it is preferable that upper cover door 61 is by the first hinged set 611 and the second hinged set 612 and casing 1 It is hinged, motor 62 is located between the first hinged set 611 and the second hinged set 612, the first drive shaft 622 passes through the first hinged set 611 are connected with upper cover door 61, and the second drive shaft 623 is connected by the second hinged set 612 with upper cover door 61.Due to upper Lid door 61 is hinged by the first hinged set 611 and the second hinged set 612 with casing 1, and such upper cover door 61 can be hinged around first The hinged set 612 of set 611 and second is rotated with the pin joint of casing 1, the opening and closing of upper cover door 61 is not only facilitated, while also ensure that Upper cover door 61 does not misplace during being opened and closed.In addition, two drive shafts are connected by two hinged sets with upper cover door 61, Such connection not only simple structure, and transmission efficiency can also be improved, additionally, two hinged sets take up room it is smaller, can So that the more compact structure of upper cover door 61.
It should be noted that:First drive shaft 622 is connected by the first hinged set 611 with upper cover door 61, and second drives Moving axis 623 is connected with upper cover door 61 by the second hinged set 612 and refers to that two drive shafts coordinate respectively with two hinged sets, Two hinged set synchronous axial systems can be driven when two drive shaft turns, and then drives upper cover door 61 around the first hinged set 611 and second hinged set 612 rotate with the pin joint of casing 1.
Because upper cover door 61 is to drive the hinged set of its both sides to rotate by two drive shafts by motor 62, such upper cover door 61 opening and closing when stress compare balance, when upper cover door 61 is closed, can by the motor damping device inside motor 62 So that upper cover door 61 is slowly closed.
In order to the installing space and two that ensure motor 62 drive load on axle to be evenly distributed, it is preferable that as shown in figure 22, Motor 62 is arranged near the first hinged set 611, is supported by bearing 624 between the second drive shaft 623 and casing 1.Wherein, motor 62 positions for being arranged close to the first hinged set 611 are installed, and so ensure that motor 62 has enough installing spaces, are prevented Interfere with the grade part of upper cover door 61 when being only arranged on two hinged set centre positions.Because motor 62 is near the one of upper cover door 61 Side is installed, and so makes the length of the second drive shaft 623 long, and a bearing is arranged between the second drive shaft 623 and casing 1 624, can so play a part of support to the second drive shaft 623, the load distribution in the second drive shaft 623 is optimized, prevent Only the deformation of the other end of the second drive shaft 623 is excessive.Certainly, motor 62 can also be arranged near the second hinged set 612, and first drives Supported by bearing 624 between axle 622 and casing 1, its effect is identical with the former.
Figure 19 show driving means and passes through another kind of alternative construction that tie point at two applies driving force to upper cover door 61, Specifically, driving means include motor 62 and auxiliary door opening mechanism 64, and motor 62 includes motor driving shaft 621, motor driving shaft 621 are connected with upper cover door 61, and auxiliary door opening mechanism 64 is arranged in upper cover door 61 away from the side of motor 62, auxiliary door opening Mechanism 64 can be to the provided auxiliary enabling torque of upper cover door 61.
Because auxiliary door opening mechanism 64 is arranged in upper cover door 61 away from the side of motor 62, and auxiliary door opening mechanism 64 All can be acted on by torque both sides when opening to the provided auxiliary enabling torque of upper cover door 61, such upper cover door 61, both sides hold Balance is easily kept, and then the side when opening of upper cover door 61 can be avoided to be subject to torque, the upper cover door 61 that opposite side is not caused Buckling deformation.
Referring to Figure 20, it is preferable that auxiliary door opening mechanism 64 includes being provided with rotatable first turn in housing 640, housing 640 Axle 643, first rotating shaft 643 is connected by transmission mechanism with upper cover door 61, and torsion spring 648 is arranged with first rotating shaft 643, is turned round The first end of spring 648 is fixed with housing 640, and the second end of torsion spring 648 is fixed relative to first rotating shaft 643, on closing is described During lid door 61, the rotating torque of upper cover door 61 can be passed to first rotating shaft 643 by transmission mechanism, rotate first rotating shaft 643, with Torsion spring 648 is set to store power, when upper cover door 61 is opened, the righting moment of torsion spring 648 can be passed by first rotating shaft 643 and transmission mechanism Upper cover door 61 is passed, with to the provided auxiliary enabling torque of upper cover door 61.
Because when upper cover door 61 is closed, the rotating torque of upper cover door 61 can be passed to first rotating shaft 643 by transmission mechanism, Rotate first rotating shaft 643, so that torsion spring 648 stores power, torsion spring 648 stores the torsional moment produced by power can slow down upper cover door 61 Closing velocity, therefore, auxiliary door opening mechanism 64 can make the soft slow closing of upper cover door 61.When upper cover door 61 is opened, torsion spring 648 Righting moment upper cover door 61 can be passed to by first rotating shaft 643 and transmission mechanism, with to the provided auxiliary of upper cover door 61 open the door Torque, and then the maximum enabling torque of motor 62 can be reduced, thus can replace high-torque using little torque motor 62 Motor 62, because auxiliary door opening mechanism 64 is frame for movement, reliability is higher, therefore, coordinate auxiliary to open with little torque motor 62 Door mechanism 64 can improve efficiency, reduces cost substituting electric motor with large torque 62.In addition, the enabling torque of motor 62 is reduced, The both sides force unbalance of upper cover door 61 can be avoided to cause warping phenomenon.Additionally, the second end of torsion spring 648 is relative to first rotating shaft 643 fix, and so when first rotating shaft 643 is rotated, the second end of torsion spring 648 will rotate with first rotating shaft 643, due to The first end of torsion spring 648 is fixed on casing will not be rotated with first rotating shaft 643, and the end of such torsion spring 648 second turns with respect to first end It is dynamic, so that torsion spring 648 produces torsional moment or righting moment.
Wherein, transmission mechanism can be speed booster driving mechanism, and upper cover door 61 is connected with the high speed level of transmission mechanism, first turn Axle 643 is connected with the slow speed turbine stage of transmission mechanism.In addition, as shown in figure 20, transmission mechanism can also be reduction gearing mechanism, upper lid Door 61 is connected with the slow speed turbine stage of transmission mechanism, and first rotating shaft 643 is connected with the high speed level of transmission mechanism, compares step-up drive machine Structure, transmission mechanism is reduction gearing mechanism, when upper cover door 61 is opened or closed, torsion spring 648 can produce one it is larger Windup-degree, and then bigger righting moment or torsional moment can be provided reducing enabling torque or the reduction of motor 62 The closing speed of upper cover door 61.
It should be noted that:In the elastic limit of torsion spring 648, the windup-degree of torsion spring 648 is bigger, required twisting resistance Square is bigger, and the provided righting moment that restPoses of torsion spring 648 is also bigger.
Further, transmission mechanism can be various, such as Chain conveyer, V belt translation etc., in addition, transmission mechanism can also be Gear drive, specifically, as shown in figure 20, transmission mechanism includes the second rotating shaft 642 and the 3rd being rotationally connected with housing 640 Rotating shaft 641, between the rotating shaft 642 of first rotating shaft 643 and second by first gear 647 groups be connected, the second rotating shaft 642 and Between three rotating shafts 641 by second gear 646 groups be connected, the 3rd rotating shaft 641 is relatively fixed with upper cover door 61.Compare chain biography Dynamic, V belt translation etc., gear drive makes the more compact structure of auxiliary door opening mechanism 64, makes the gearratio of transmission mechanism more accurate, passes Efficiency of movement is higher, and driving torque is bigger.In addition, passing through 647 groups of biographies of first gear between the rotating shaft 642 of first rotating shaft 643 and second Dynamic connection, between the second rotating shaft 642 and the 3rd rotating shaft 641 by second gear 646 groups be connected, by two gear trains biographies It is dynamic, so can reasonably distribute the gearratio of each gear train to avoid gearratio excessive or too small.Wherein, the 3rd rotating shaft 641 are relatively fixed with upper cover door 61, so will drive the synchronous rotary of the 3rd rotating shaft 641 when upper cover door 61 rotates.
It should be noted that:First rotating shaft 643, the second rotating shaft 642 and the 3rd rotating shaft 641 are to rotate to connect by bearing 649 It is connected in housing 640, six bearings 649 are symmetrically set in housing 640, and three rotating shafts are played a supportive role respectively.
Wherein, gear can be fixed in rotating shaft, such as gear is welded in rotating shaft, it is also possible to by gear and rotating shaft one Body is designed, in addition, as shown in figure 20,647 groups of first gear includes intermeshing first gear 647 and second gear 646, the One gear 647 is sheathed in first rotating shaft 643, and second gear 646 is sheathed in the second rotating shaft 642, and 646 groups of second gear includes Intermeshing 3rd gear 645 and the 4th gear 644, the 3rd gear 645 is sheathed in the second rotating shaft 642, the 4th gear 644 It is sheathed in the 3rd rotating shaft 641.Compare gear be fixed on axle or with axle Integral design, four gears are sheathed in rotating shaft, When so there is broken teeth, abrasion etc. and fail in gear, it is possible to easily disassemble from rotating shaft, without changing rotating shaft, Reduce maintenance cost.Additionally, diameter of the diameter of first gear 647 less than second gear 646, the diameter of the 3rd gear 645 Less than the diameter of the 4th gear 644, such first rotating shaft 643 to the 3rd rotating shaft 641 belongs to double reduction transmission, reasonably distributes Gearratio.
