DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Regarding the related technologies, the standardized suspension support cushion cannot adapt well to the vibration excitation caused by various road surfaces, engines, etc., which may cause damage to the cooling module and deterioration of the ride comfort of the entire vehicle.

[0040] It should be noted that for the cooling module support system, the theoretical formula for avoiding resonance, improving vibration isolation rate, and controlling module displacement is as follows to improve the reliability of the cooling module and the ride comfort of the vehicle:

[0041] Formula 1: Engine ignition frequency f F :

[0042]

[0043] Where: n is the engine speed in revolutions per minute (rpm), i is the number of engine cylinders, τ is the stroke coefficient, which is 1 for two-stroke and 2 for four-stroke.

[0044] Formula 2: Self-oscillation frequency:

[0045]

[0046] Among them: K is stiffness; M is suspended mass.

[0047] Formula 3: Vibration transmissibility:

[0048]

[0049] Where: Rf is the frequency ratio and c is the damping ratio.

[0050] From the analysis of the above theoretical formulas, due to the engine ignition frequency, the excitation of the frame is variable. In order to avoid the resonance area or stay away from the resonance area, according to Formula 1 and Formula 2, the stiffness needs to be variable to adapt. If the stiffness is a constant, it cannot adapt well to the needs of changes in the excitation source and can only ensure that no resonance occurs under common working conditions. According to Formula 3, when approaching the resonance area, in order to ensure that the vibration amplitude is reduced, the damping ratio is changed to adapt.

[0051] First, as Figure 1 As shown, the embodiment of the present application provides a cooling module suspension device, the cooling module suspension device comprises: a main support cushion body 5, a second connecting plate 2 and a first connecting plate 1; wherein,

[0052] A main support cushion body 5, whose symmetrical two sides are respectively used to connect with the cooling module 3 and the frame 4; a second connecting plate 2, which is connected to the main support cushion body 5, and the second connecting plate 2 is used to be attached between the main support cushion body 5 and the frame 4; a first connecting plate 1, one side of which is connected to the main support cushion body 5, and the other side is used to connect with the cooling module 3, the first connecting plate 1 is provided with a protrusion 13 set in a gap with the main support cushion body 5, the protrusion 13 is used to connect with the cooling module 3, the protrusion 13 can be deformed after being subjected to force and abut against the main support cushion body 5, so as to increase the area of ​​the fitting surface between the main support cushion body 5 and the first connecting plate 1.

[0053] It can be understood that the main support cushion body 5, the second connecting plate 2 and the first connecting plate 1 constitute the main support structure of the cooling module suspension device. The main support structure isolates the vibration transmitted from the frame, contains and reduces the influence of the additional stress on the cooling module caused by the deformation of the frame; in addition, by adjusting the stiffness of the main support, the resonance is avoided or reduced, and the reliability and durability of the cooling module and the smoothness of the whole vehicle are improved.

[0054] Furthermore, the second connecting plate 2 and the first connecting plate 1 are vulcanized into a whole. Figure 1 As shown, the vulcanized bonding surface between the first connecting plate 1 and the main supporting cushion body 5 is a constraint surface, and the other free open surfaces are free surfaces. At the same time, the gap between the protrusion 13 of the first connecting plate 1 and the main supporting cushion body 5 forms a variable free surface. When the protrusion 13 is deformed and pressed down to contact the main supporting cushion body 5, the variable free surface becomes a constraint surface, and the stiffness of the part of the main supporting cushion body 5 originally under the variable free surface becomes larger.

[0055] Preferably, the raised portion 13 is a conical surface, which is used to cooperate with the circular hole on the bracket of the cooling module 3 and can be automatically positioned during assembly.

[0056] It is worth noting that, in the present application, a deformable protrusion 13 is provided on the first connecting plate 1. When the protrusion is subjected to the weight of the cooling module and the acceleration changes, it will be deformed and pressed down, and will come into contact with the main supporting cushion body 5, thereby changing the area of ​​the supporting surface of the main supporting cushion body 5 and the first connecting plate 1, thereby increasing the rigidity of the main supporting structure. In the present application, the deformation of the protrusion 13 can make the cooling module suspension device switch between the first state and the second state; wherein,

[0057] When the cooling module suspension device is in a first state, the first connecting plate 1 is not deformed, and the area of ​​the fitting surface between the main support cushion body 5 and the first connecting plate 1 remains unchanged; when the cooling module suspension device is in a second state, part of the first connecting plate 1 is deformed and abuts against the main support cushion body 5, so that the area of ​​the fitting surface between the main support cushion body 5 and the first connecting plate 1 is increased.

[0058] Furthermore, the fitting surface between the main support cushion body 5 and the first connecting plate 1 is the support force receiving surface between the main support cushion body 5 and the first connecting plate 1, and thus changing the area of ​​the fitting surface is used as a variable free surface design, thereby changing the stiffness of the main support structure.

[0059] In combination with the first aspect, in one embodiment, the first connecting plate 1 includes a first plate body 11 and a limiting thread groove 12 connected as one body. The second connecting plate 2 includes a second plate body 21 and a pin 22 connected as one body, the second plate body 21 is spaced apart from the limiting thread groove 12, and the limiting thread groove 12 is connected to the limiting thread groove 12 via the pin 22.

[0060] It is worth mentioning that the limiting thread groove 12 and the second connecting plate 2 form a limiting structure. Combined with the gap control between the limiting thread groove 12 and the second connecting plate 2, a physical limit of the maximum limit displacement in all directions of the entire main support is formed to avoid damage to the cooling module 3 due to excessive displacement under special circumstances.

[0061] In combination with the first aspect, in a preferred embodiment, a mounting groove is provided in the main support cushion body 5, and the mounting groove and the second connecting plate 2 form a receiving cavity. Preferably, a stiffness adjustment component 6 and / or a first damping component 7 are provided in the receiving cavity, and the stiffness adjustment component 6 can change its contact area with the surface of the receiving cavity, and the first damping component 7 is connected to the main support cushion body 5.

[0062] It can be understood that, as described above, the first damping component 7 is used to change the damping ratio of the main support structure so that the main support structure can ensure that the vibration amplitude is reduced. The stiffness adjustment component 6 cooperates with the protrusion 13 in the above embodiment to change the stiffness of the main support structure. When used specifically, the stiffness adjustment component 6 or the first damping component 7 can be installed in the main support cushion body 5 alone. It is also possible to install the stiffness adjustment component 6 and the first damping component 7 in the main support cushion body 5 at the same time.

[0063] It is worth noting that according to the design of the rubber shock-absorbing cushion, there are two main principles of variable stiffness: one is the design of a cushion with a variable cross section, and the other is to control the free surface area of ​​the rubber by changing the area. The present application combines the design of the cushion with a variable cross section of the stiffness adjustment component 6 with the design of adjusting the free surface area formed by the deformable protrusion 13. The full range of variable stiffness is achieved, thereby widening the scope of application.

[0064] In combination with the above specific implementation manner, Figure 3 and Figure 4 As shown, in some specific embodiments, the stiffness adjustment component 6 includes: a rotating part 61 and a driving member 62; wherein,

[0065] A rotating part 61 is installed in the storage cavity, and part of the rotating part 61 can be rotated to abut against or separate from the surface of the storage cavity; a driving member 62 is installed in the storage cavity, the driving member 62 is connected to the second connecting plate 2, and a telescopic member 63 is provided on the driving member 62, and the telescopic member 63 corresponds to the position of the rotating part 61. The driving member 62 can drive the telescopic member 63 to perform a telescopic action to drive the rotating part 61 to rotate.

[0066] Furthermore, the rotating part 61 includes: a fixed plate 611, a rotating plate 612 and an elastic member 613; wherein,

[0067] A fixed plate 611 is attached to the second connecting plate 2; a rotating plate 612 is rotatably hinged with the fixed plate 611; an elastic member 613 is provided on the fixed plate 611, the elastic member 613 abuts against the rotating plate 612, and drives the rotating plate 612 to always abut against the telescopic member 63.

[0068] It is understandable that the elastic member 613 is always in a compressed state, so that there is no gap between the rotating plate 612 and the telescopic member 63, thereby avoiding the impact noise between the two caused by the gap. When in use, the driving member 62 is an actuator, and the driving member 62 can be a cylinder or an oil cylinder. The driving member 62 pushes the telescopic member 63 to extend and retract, and the telescopic member 63 pushes the variable-angle rotating plate 612 to deflect the angle, thereby changing the contact surface area between the rotating plate 612 and the surface of the storage cavity, thereby actively changing the stiffness.

[0069] In combination with the above specific implementation manner, Figure 2 As shown, in some specific embodiments, the first damping assembly 7 includes: a damping cylinder 71 and a piston 72; wherein,

[0070] The damping cylinder 71 is connected to the second connecting plate 2; the piston member 72 has one end connected to the first connecting plate 1 and the other end extending into the damping cylinder 71 and can move in the damping cylinder 71. The medium in the damping cylinder 71 can be oil or other medium (such as air). Preferably, a dust cover is provided on the outside of the piston member 72 to prevent foreign dust or impurities from entering and affecting the operation.

[0071] Furthermore, the damping cylinder 71 is provided with a damping adjustment part 73, and the damping adjustment part 73 is used to adjust the size of the medium space in the damping cylinder 71. Specifically, the damping adjustment part 73 includes a medium hole provided on the damping cylinder 71 and an aperture adjustment device extending outside, and by adjusting the aperture adjustment device extending outside, the size of the medium hole is changed to achieve the purpose of adjusting the damping.

[0072] In some preferred implementations, Figure 5 and Figure 8 As shown, the cooling module suspension device also includes: an auxiliary support assembly 8, which includes two auxiliary support rods 81, one end of the two auxiliary support rods 81 are staggered with each other and connected by an auxiliary cushion 82, and the other end of the two auxiliary support rods 81 are respectively used to connect to the cooling module 3 and the frame 4.

[0073] It should be noted that the general function of the auxiliary support is to prevent the cooling module from being displaced significantly, thereby preventing weak links of components such as the cooling module from being damaged during twisting.

[0074] Furthermore, if Figure 6As shown, an auxiliary cushion 82 made of vulcanized rubber is used between the two auxiliary support rods 81 to form a whole. The two auxiliary support rods 81 are staggered to limit the stretching and compression of the auxiliary cushion 82, thereby preventing the cooling module 3 from being displaced greatly on the vehicle.

[0075] In some preferred embodiments, the auxiliary support rod 81 includes a support rod 811 with threads and a bracket 812 with threaded holes. Both support rods 811 are connected to the auxiliary cushion 82, and the ends of the two support rods 811 are staggered. One end of the bracket 812 is connected to the frame 4 or the cooling module 3, and the other end is threadedly connected to the support rod 811.

[0076] It is understandable that the bracket 812 is a replaceable part and can be adapted to different vehicle models by changing the length. Further, the bracket 812 can absorb installation errors by the screw-in length and angle of the thread.

[0077] In some other preferred implementations, Figure 7 As shown, the auxiliary support rod 81 is provided with a second damping assembly 9. Specifically, the second damping assembly 9 is arranged in the extended support rod 811, and a cavity is provided therein to accommodate the second damping assembly 9. Similarly, an oil cylinder or an air cylinder can be used to make part of the second damping assembly 9 move in the auxiliary cushion 82. A throttling hole is provided in the oil cylinder or the air cylinder to achieve a damping effect by throttling the internal medium.

[0078] Furthermore, the second damping assembly 9 is also applicable to the above-mentioned embodiment of the main support structure. The auxiliary support rod 81 and the second damping assembly 9 can be made into an integral type or a separate type.

[0079] In a second aspect, the present application provides an automobile, which includes: a cooling module suspension device, the cooling module suspension device includes: a main support cushion body 5, a second connecting plate 2 and a first connecting plate 1; wherein,

[0080] A main support cushion body 5, whose symmetrical two sides are respectively used to connect with the cooling module 3 and the frame 4; a second connecting plate 2, which is connected to the main support cushion body 5, and the second connecting plate 2 is used to be attached between the main support cushion body 5 and the frame 4; a first connecting plate 1, one side of which is connected to the main support cushion body 5, and the other side is used to connect with the cooling module 3, the first connecting plate 1 is provided with a protrusion 13 set in a gap with the main support cushion body 5, the protrusion 13 is used to connect with the cooling module 3, the protrusion 13 can be deformed after being subjected to force and abut against the main support cushion body 5, so as to increase the area of ​​the fitting surface between the main support cushion body 5 and the first connecting plate 1.

[0081] It can be understood that the main support cushion body 5, the second connecting plate 2 and the first connecting plate 1 constitute the main support structure of the cooling module suspension device.

[0082] Furthermore, the second connecting plate 2 and the first connecting plate 1 are vulcanized into a whole. Figure 1 As shown, the vulcanized bonding surface between the first connecting plate 1 and the main supporting cushion body 5 is a constraint surface, and the other free open surfaces are free surfaces. At the same time, the gap between the protrusion 13 of the first connecting plate 1 and the main supporting cushion body 5 forms a variable free surface. When the protrusion 13 is deformed and pressed down to contact the main supporting cushion body 5, the variable free surface becomes a constraint surface, and the stiffness of the part of the main supporting cushion body 5 originally under the variable free surface becomes larger.

[0083] Preferably, the raised portion 13 is a conical surface, which is used to cooperate with the circular hole on the bracket of the cooling module 3 and can be automatically positioned during assembly.

[0084] It is worth noting that, in the present application, a deformable protrusion 13 is provided on the first connecting plate 1. When the protrusion is subjected to the weight of the cooling module and the acceleration changes, it will be deformed and pressed down, and will come into contact with the main supporting cushion body 5, thereby changing the area of ​​the supporting surface of the main supporting cushion body 5 and the first connecting plate 1, thereby increasing the rigidity of the main supporting structure.

[0086] Furthermore, the fitting surface between the main support cushion body 5 and the first connecting plate 1 is the support force receiving surface between the main support cushion body 5 and the first connecting plate 1, and thus changing the area of ​​the fitting surface is used as a variable free surface design, thereby changing the stiffness of the main support structure.

[0087] In combination with the first aspect, in one embodiment, the first connecting plate 1 includes a first plate body 11 and a limiting thread groove 12 connected as one body. The second connecting plate 2 includes a second plate body 21 and a pin 22 connected as one body, the second plate body 21 is spaced apart from the limiting thread groove 12, and the limiting thread groove 12 is connected to the limiting thread groove 12 via the pin 22.

Combined with the gap control between the limiting thread groove 12 and the second connecting plate 2, a physical limit of the maximum limit displacement in all directions of the entire main support is formed to avoid damage to the cooling module 3 due to excessive displacement under special circumstances.

[0099] Furthermore, the damping cylinder 71 is provided with a damping adjustment part 73, and the damping adjustment part 73 is used to adjust the size of the medium space in the damping cylinder 71. Specifically, the damping adjustment part 73 includes a medium hole provided on the damping cylinder 71 and an aperture adjustment device extending outside, and by adjusting the aperture adjustment device extending outside, the size of the medium hole is changed to achieve the purpose of adjusting the damping.

[0100] In some preferred implementations, Figure 5and Figure 8 As shown, the cooling module suspension device also includes: an auxiliary support assembly 8, which includes two auxiliary support rods 81, one end of the two auxiliary support rods 81 are staggered with each other and connected by an auxiliary cushion 82, and the other end of the two auxiliary support rods 81 are respectively used to connect to the cooling module 3 and the frame 4.

[0101] It should be noted that the general function of the auxiliary support is to prevent the cooling module from being displaced significantly, thereby preventing weak links of components such as the cooling module from being damaged during twisting.

[0102] Furthermore, if Figure 6 As shown, an auxiliary cushion 82 made of vulcanized rubber is used between the two auxiliary support rods 81 to form a whole. The two auxiliary support rods 81 are staggered to limit the stretching and compression of the auxiliary cushion 82, thereby preventing the cooling module 3 from being displaced greatly on the vehicle.

[0103] In some preferred embodiments, the auxiliary support rod 81 includes a support rod 811 with threads and a bracket 812 with threaded holes. Both support rods 811 are connected to the auxiliary cushion 82, and the ends of the two support rods 811 are staggered. One end of the bracket 812 is connected to the frame 4 or the cooling module 3, and the other end is threadedly connected to the support rod 811.

[0104] It is understandable that the bracket 812 is a replaceable part and can be adapted to different vehicle models by changing the length. Further, the bracket 812 can absorb installation errors by the screw-in length and angle of the thread.

[0105] In some other preferred implementations, Figure 7 As shown, the auxiliary support rod 81 is provided with a second damping assembly 9. Specifically, the second damping assembly 9 is arranged in the extended support rod 811, and a cavity is provided therein to accommodate the second damping assembly 9. Similarly, an oil cylinder or an air cylinder can be used to make part of the second damping assembly 9 move in the auxiliary cushion 82. A throttling hole is provided in the oil cylinder or the air cylinder to achieve a damping effect by throttling the internal medium.

[0106] Furthermore, the second damping assembly 9 is also applicable to the above-mentioned embodiment of the main supporting structure. The auxiliary support rod 81 and the second damping assembly 9 can be made into an integral type or a separate type.

[0107] In summary, the applicant found that due to the engine ignition frequency, the excitation of the frame is variable, in order to avoid the resonance zone or stay away from the resonance zone. If the stiffness is a constant value, it cannot adapt well to the needs of changes in the excitation source, and can only ensure that there is no resonance under common working conditions. Therefore, the stiffness of the main support structure needs to change to adapt. The present application sets a deformable protrusion on the first connecting plate. When the protrusion is subjected to the weight of the cooling module and the acceleration changes, it will deform and press down, and contact with the main support cushion body, thereby changing the area of ​​the main support cushion body and the first connecting plate The support surface is fitted, thereby increasing the stiffness of the main support structure.
