In the process of running, on-vehicle battery packet is at every moment by the vibration from road surface and power assembly for electric car Excitation, so that the battery pack cabinet of on-vehicle battery packet is easy to appear Fatigue Failures.When fatigue failure occurs in battery pack cabinet When problem, battery pack cabinet will lose fixation and protective effect to wherein battery component, so that battery inevitably occurs It is the problems such as situations such as displacement, play and extruding, damaged, circuit connecting relation destroys so as to cause battery module structure, gently then electric Pond performance impairment, service life cycle reduce, heavy then power off stall, to lose control of one's vehicle in traveling suddenly, or even generation spark discharge The major accidents such as vehicle fire, burning are caused to occur.Therefore, how to control in electric car operational process suffered by on-vehicle battery packet To vibration influence be particularly important.The object that the following two kinds mode needs vibration isolation to on-vehicle battery packet etc. is generallyd use at present Carry out vibration control.
First method: increasing the object rigidity that on-vehicle battery packet etc. needs vibration control, so that on-vehicle battery packet etc. needs It wants the natural frequency of object of vibration control to increase, needs the object of vibration control to vibrational excitation to reduce on-vehicle battery packet etc. Response, improve its fatigue life.But the suffered vibration of on-vehicle battery packet can not be completely inhibited in this way, and In order to improve the natural frequency of object for needing vibration control, the weight of on-vehicle battery packet be will increase very much, this seriously reduces vehicle The energy density for carrying battery pack, so that the course continuation mileage of electric car reduces.
Second method: vibration isolation processing is carried out to on-vehicle battery packet using vibration isolation technique.Isolation mounting is introduced, with isolation Influence of the vibrational excitation to on-vehicle battery packet.But electric car industry seldom carries out vibration isolation processing to on-vehicle battery packet.And Other industry, although vibration isolation technique is relatively common, the intrinsic frequency for the vibrating isolation system that isolation mounting and vibration isolation object are constituted It is necessarily less than vibrational excitation frequency, so that when vibrational excitation frequency is very low, for the vibrational excitation that the vibrational excitation frequency is isolated The intrinsic frequency in source, vibrating isolation system can further decrease.And vibrating isolation system intrinsic frequency and vibrating isolation system Stiffness Distribution with Mass Distribution has relationship, the vibration isolation object quality size and in the case where constant Mass Distribution in vibrating isolation system, can only reduce every The rigidity of vibrating device elastic element reduces the intrinsic frequency of vibrating isolation system.But the rigidity ratio of isolation mounting elastic element When lower, when not having vibrational excitation, the rigid displacement of vibration isolation object is bigger so that vibration isolation object be easy with its near Component occurs hitting or pullling phenomenon.It should be understood that the load of vibration isolation object is static state when vibration isolation object is not vibrated excitation Load.When vibration isolation object is vibrated excitation, the load of vibration isolation object is dynamic load.
As shown in Figure 1, the embodiment of the present application provides a kind of vibrating isolation system, which includes at least one vibration isolation dress Set 100 and vibration isolation object 200.Vibration isolation object 200 is fixed together at least one isolation mounting 100.The vibration isolation object can be with For above-mentioned on-vehicle battery packet, the object of vibration isolation can also be needed with other.The vibrating isolation system is not vibrated the vibration of driving source 300 When dynamic excitation, all isolation mountings 100 have enough rigidity, to guarantee that vibration isolation object 200 is not easy to go out with its neighbouring component Now hit or pull phenomenon.Meanwhile the vibrating isolation system, when being vibrated excitation, all isolation mountings 100 are to vibration isolation object 200 With enough vibration isolation capabilities.Fig. 1 shows a kind of vibrating isolation system, wherein only containing a vibration isolation object 200, but is not precluded The vibrating isolation system includes the case where at least two vibration isolation objects 200.
In some possible implementations, in order to guarantee that the embodiment of the present application vibrating isolation system is imitated with good vibration isolation Fruit, as shown in Figure 1, isolation mounting 100 is divided into elastic element 101 according to vibration isolation principle in the embodiment of the present application and damping is first Part 102, vibration stimulus source 300 to be isolated as far as possible using elastic element 101 and damping element 102, thus it is as less as possible general Vibration is transmitted to damping object.Elastic element 101 and damping element 102 usually select spring-damper system, and damping can be rubber Blob of viscose etc..Based on this, by using carry-over factor T evaluate isolation mounting 100 vibration isolating effect, for isolation mounting 100 with every For the vibrating isolation system that vibration object 200 is constituted, the carry-over factor formula of transmission system is as follows:
ωeFor vibrational excitation frequency；ωnFor the intrinsic frequency of vibrating isolation system；λ is frequency ratio；ζ is vibration isolation as shown in Figure 1 The damping ratio for the vibrating isolation system that device 100 and vibration isolation object 200 form, k are the rigidity of isolation mounting 100, and M is elastic object Quality.
It is required according to vibration isolation, when carry-over factor T is less than 1, illustrates that vibration isolation is effective, otherwise vibration isolation is invalid.Based on this, according to biography Delivery system formula is it is found that work asWhen, i.e.,When, vibration isolation is just effective.Certainly, which can also To be obtained by carry-over factor illustrated in fig. 2, frequency than the trend chart with damping ratio.

The embodiment of the present application also provides a kind of isolation mounting 100, can be used for on-vehicle battery packet as shown in Figure 5 510 carry out vibration isolation, and the vibration isolation object of vibration isolation can also be needed to carry out vibration isolation to other.As shown in figure 8, the isolation mounting 100 wraps Include pedestal 110, spring part 120 and the elastic supporting beams 130 for being used to support vibration isolation object 200.Elastic supporting beams 130 are fixed on On pedestal 110, spring part 120 is between pedestal 110 and elastic supporting beams 130；Elastic supporting beams 130 are used in vibration isolation object 200 occur linear buckling when being vibrated excitation, and can be promptly restored to after vibrational excitation disappears, there is no now linear Song state in the wrong.For above-mentioned vibrating isolation system, as shown in fig. 6, vibration isolation object 200 can be located at least one isolation mounting Included surface of the elastic supporting beams 130 far from spring part 120；It is also possible to vibration isolation object 200 and is located at least one vibration isolation Surface of the pedestal 110 far from spring part 120 included by device.
As shown in Figure 7 and Figure 8, in the embodiment of the present application isolation mounting 100, spring part 120 is located at pedestal 110 and elasticity is propped up It supports between beam 130, when so that the vibration isolation objects 200 such as on-vehicle battery packet 510 shown in Fig. 4 not being vibrated excitation, vibration isolation Device 100 has enough rigidity, is not being shaken to reduce the vibration isolation objects 200 such as on-vehicle battery packet 510 shown in Fig. 4 To reduce vibration isolation object 200 and its neighbouring component the machine for hitting or pullling occurs for the rigid displacement amount in the case where dynamic excitation Rate.As shown in figure 8, since when vibration isolation object 200 is vibrated excitation linear buckling occurs for elastic supporting beams 130, In When the vibration isolation objects 200 such as on-vehicle battery packet 510 shown in Fig. 4 are vibrated excitation, elastic supporting beams 130 can be in vibrational excitation After the lower generation linear buckling of effect, so that spring part 120 and the decline of the global stiffness of elastic supporting beams 130, and then reduce vibration isolation dress The rigidity set, to guarantee that isolation mounting 100 can play the role of vibration isolation, to reduce vibrational excitation to vibration isolation pair such as on-vehicle battery packets As 200 influence.
It is below that the application implementation is described in detail in vibration isolation object 200 shown in FIG. 1 with on-vehicle battery packet 510 shown in Fig. 4 The vibration isolation principle for the isolation mounting 100 that example provides.It is hereafter only used for explaining the vibration isolation principle of the application isolation mounting 100, not For limiting.
In no extraneous vibration source, on-vehicle battery packet 510 shown in Fig. 4 is not vibrated excitation.Such as: such as Fig. 6 institute Show, when electric car electric drive does not start or electric car is not run, on-vehicle battery packet 510 is not vibrated sharp It encourages.Under the Gravitative Loads of on-vehicle battery packet, battery pack cabinet 511 shown in Fig. 7 passes through the positioning contained by positioning component 400 Column 410 transfers loads on isolation mounting 100, so that isolation mounting 100 is born centainly under on-vehicle battery packet Gravitative Loads Lower pulling force.At this point, as shown in figure 8, static load suffered by elastic supporting beams 130 makes it remain at stable structure shape State.Certainly, since spring part 120 is between elastic supporting beams 130 and pedestal 110, spring part 120 is also at structure Stable state.Since spring part 120 and elastic supporting beams 130 are in stable structure state, so that spring part 120 and elasticity branch Supportting rigidity possessed by beam 130 is substantially the sum of rigidity and rigidity of elastic supporting beams 130 of spring part 120, therefore, spring part 120 and elastic supporting beams 130 under the premise of not losing stable structure, spring part 120 and elastic supporting beams 130 bear enough because For lower pulling force suffered by on-vehicle battery packet Gravitative Loads.
When there is extraneous vibration source, on-vehicle battery packet is vibrated excitation.Such as: as shown in figure 4, working as electric car electric drive Be activated or when electric car is run, on-vehicle battery packet 510 will by from road surface and motor 330 and retarder 340 etc. outside The vibrational excitation on boundary.As shown in fig. 7, the moment that on-vehicle battery packet 510 shown in Fig. 4 will vibrate, with vehicle shown in Fig. 4 Carry dynamic load suffered by elastic supporting beams 130 included by all isolation mountings that are fixed together of battery pack 510 be greater than with Static load of all isolation mounting on-vehicle battery packets that on-vehicle battery packet is fixed together when not being vibrated excitation, makes The elastic supporting beams 130 that stable structure state is in front of obtaining reach the critical point of linear buckling and linear buckling occur. When linear buckling occurs for elastic supporting beams 130,130 collapsing unstability of elastic supporting beams, so that elastic supporting beams 130 bear load Ability decline, therefore, the vibrating isolation system that isolation mounting 100 and on-vehicle battery packet are constituted can meet vibration isolation condition and start to vehicle It carries battery pack and carries out vibration isolation, is i.e. intrinsic frequency of the vibrating isolation system when being vibrated excitation is less than vibrational excitation frequency 0.707 times.It should be understood that should be guaranteed that the buckling type that elastic supporting beams 130 shown in Fig. 8 occur is linear buckling, Cai Neng When dynamic exciting suffered by on-vehicle battery packet 510 shown in Fig. 4 disappears, elastic supporting beams 130 shown in Fig. 8 restore rapidly former The stable state come, i.e., the load carrying capacity of elastic supporting beams 130 shown in Fig. 8 are restored to the not journey by dynamic exciting Degree.
In some embodiments, Figure 10 shows a kind of structural schematic diagram of elastic supporting beams 130.As shown in Figure 10, should Elastic supporting beams 130 include support plate 132 and at least three fixed wings 133 for being used to support plate 132, at least three fixed wings 133 are located at the circumferential direction of support plate 132, and the tail end of at least three fixed wings 133 is fixed on pedestal 110.As for fixed wings 133 Quantity may be set according to actual conditions, but should not be less than three, and otherwise the stability of support plate 132 is difficult to ensure.
As shown in figure 8, above-mentioned fixed wings 133 are between elastic supporting beams 130 and pedestal 110.Due at least three solid The circumferential direction that wing 133 is located at support plate 132 is determined, and its tail end is fixed on pedestal 110, so that at least three fixed wings, 133 shape Support plate 132 is supported at multiple support constructions, to guarantee that support plate 132 can compare when not being vibrated excitation It is more stable, so that isolation mounting 100 has enough rigidity.
In some embodiments, as shown in Figure 10, at least three fixed wings 133 are uniformly located at the circumferential direction of support plate 132, With when not being vibrated excitation, support plate has better stability.
In some embodiments, as shown in Figure 10, each fixed wings 133 are the fixed wings of zigzag structure.Each fixed wings 133 include at least head connecting plate 1331, middle connecting plate 1332 and the tail portion connecting plate 1333 being successively connected.The support The edge of plate is fixed together with head connecting plate 1331 far from one end of middle connecting plate 1332, as shown in figure 8, the tail portion connects Fishplate bar 1333 is fixed together with pedestal 110.As shown in Figure 10, it is successively connected since each fixed wings 133 include at least Head connecting plate 1331, middle connecting plate 1332 and tail portion connecting plate 1333, and head connecting plate 1331, middle connecting plate 1332 and tail portion connecting plate 1333 constitute zigzag structure fixed wings 133 so that at least three fixed wings 133 support support plate It rises, to guarantee between support plate and pedestal 110 there is enough accommodation spaces to accommodate spring part 120.
Illustratively, as shown in Figure 10, in above-mentioned each fixed wings, head connecting plate 1331 and support plate are in same put down Face.It is α, middle connecting plate 1332 and tail portion connecting plate that head connecting plate 1331 and middle connecting plate 1332, which are formed by angle, 1333 are formed by that angle is β, α=β, and α and β is obtuse angle.When α and β are obtuse angle, it is ensured that be vibrated excitation When, elastic supporting beams 130 are easier that linear buckling occurs, and enable the rigidity of isolation mounting 100 when being vibrated excitation Enough reduce rapidly.As for the specific size of α and β, then the relationship of itself and linear buckling critical point can be analyzed by simulation softward, with Determine the size of α and β.

It should be understood that when being vibrated excitation, in order to enable elastic supporting beams shown in Fig. 8 130 are rapidly achieved linear bend Bent critical point, in no extraneous vibration source, above-mentioned elastic supporting beams 130 are in linear buckling Near The Critical Point, but there is no Linear buckling is in stable structure state.And whether to be in linear buckling in no extraneous vibration source critical for elastic supporting beams 130 Point near, it is not only related with the static load that elastic supporting beams 130 are born, also with 130 self structure of elastic supporting beams, shape And size is related.And the restriction of 130 self structure of elastic supporting beams, shape and size is needed quiet according to what is born It carries magnitude of load and other practical factors determines.In actual design, need to only be analyzed according to simulation softward.
In some embodiments, as shown in figure 9, said base 110 is equipped at least three for fixing fixed wings 133 Positioning table 112, to correspond to fixed wings 133 using at least three positioning tables 112 are fixed, so that support plate 132 is fixed on base The top of seat 110.As shown in Figure 10, when above-mentioned fixed wings 133 include head connecting plate 1331, middle connecting plate 1332 and tail portion When connecting plate 1333, each positioning table 112 shown in Figure 12 includes the first fixed pan 1111 and the second fixed pan 1112.Such as First fixed pan 1111 shown in Figure 12 is for fixing tail portion connecting plate 1333 as shown in Figure 10, and as shown in figure 12 second Fixed pan 1112 is for fixing middle connecting plate 1332 as shown in Figure 10.
In some embodiments, as shown in figs, fixed isolation mounting, above-mentioned support plate 132 are ring for convenience Shape support plate, to utilize positioning column included by hollow area possessed by annular support plate and positioning component 400 shown in Fig. 7 410 cooperations, elastic supporting beams 130 and pedestal 110, spring part 120 and vibration isolation object are fixed together.
Figure 13 shows the embodiment of the present application isolation mounting in the loading analysis figure of linear buckling critical state.Institute in Figure 13 The fixed wings quantity shown is three, but is not limited only to three.As seen from Figure 13, under linear buckling critical state, branch Fagging load suffered by three regions is bigger, and in the biggish region of these three load ratios, two neighboring region it Between part be fixed with a fixed wings.Meanwhile load suffered by the tail portion connecting plate of these fixed wings is also bigger, because This, under the distribution of this load, elastic supporting beams are easy to collapse.
In one possible implementation, constant in view of the overall stiffness of isolation mounting in the related technology, so that vibration isolation Intrinsic frequency of the vibrating isolation system that the vibration isolation object such as device and on-vehicle battery packet is constituted in some directions is constant.The vibrating isolation system Intrinsic frequency can only meet vibration isolation condition, therefore, phase with a certain certain vibration driving frequency in external vibration stimulus source Isolation mounting carries out vibration isolation only for the vibrational excitation of single-frequency in the technology of pass.To realize the vibration isolation in wide frequency ranges, such as Shown in Fig. 6, vibrating isolation system composed by isolation mounting 100 and on-vehicle battery packet is needed to be set as becoming the vibration isolation system of intrinsic frequency System, but it is appreciated that vibrating isolation system intrinsic frequency and the vibrating isolation system Stiffness Distribution and Mass Distribution have relationship, but The quality size of vibrating isolation system composed by isolation mounting 100 and on-vehicle battery packet with distribution be it is invariable, therefore, Zhi Nengshe A kind of isolation mounting of variation rigidity is counted, so that vibrating isolation system has wider vibrational excitation frequency.
Figure 11 shows a kind of structural schematic diagram of spring part 120.As shown in figure 11, which is curved spring Part, the curved spring part are used for the rigidity when being vibrated excitation and change.Figure 14 shows the embodiment of the present application vibration isolation dress Set the force-displacement curve figure with the relevant technologies Hookean spring.Mg is the gravity of vibration isolation object, x in Figure 14eFor in vibration isolation object The displacement of isolation mounting under gravity.A is the force-displacement curve of the application isolation mounting, the embodiment of the present application in Figure 14 Spring part 120 in isolation mounting 100 is curved spring part.B is the force-displacement curve of related isolation mounting in Figure 14, should be every Vibrating device can be Hookean spring.
By a in Figure 14 it is found that global stiffness variation of the isolation mounting provided by the embodiments of the present application within the scope of Δ x is 0, place In linear buckling critical state.And at the slope (rigidity) of the force-displacement curve of isolation mounting provided by the embodiments of the present application In variation, therefore, isolation mounting provided by the embodiments of the present application can realize the vibration isolation in wide frequency ranges.And b institute in Figure 14 The slope (rigidity) of the force-displacement curve of the existing isolation mounting shown is kept constant, and therefore, Hookean spring is only capable of in the related technology Vibration isolation is carried out to the vibrational excitation of single-frequency.
The linear buckling Critical Buckling Load of isolation mounting provided by the embodiments of the present application is the gravity of vibration isolation object herein. In not extraneous vibrational excitation (F < mg), the position of isolation mounting provided by the embodiments of the present application under same static load Shifting amount is less than the displacement of existing isolation mounting, therefore, in not extraneous vibrational excitation, it is provided by the embodiments of the present application every The rigidity of vibrating device is big relative to the rigidity of existing isolation mounting, same dynamic when by extraneous vibrational excitation (F > mg) The displacement of vibration isolation object provided by the embodiments of the present application is greater than the displacement of existing isolation mounting under state load, therefore, by To when extraneous vibrational excitation, rigidity of the rigidity of isolation mounting provided by the embodiments of the present application relative to existing isolation mounting It is small.
