[0002] The cooling module in a vehicle's cooling system consists of a radiator and intercooler, and is typically mounted on the vehicle frame.

DETAILED DESCRIPTION

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

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

[0040] It should be noted that for the cooling module support system, avoiding resonance, increasing vibration isolation, and controlling module displacement can improve the reliability of the cooling module and enhance the ride comfort of the entire vehicle. The theoretical formula is as follows:

[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, and τ is the stroke coefficient, which is 1 for a two-stroke and 2 for a four-stroke.

[0044] Formula 2: Natural frequency:

[0045]

[0046] Where: K is the stiffness; M is the 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 zone or stay away from the resonance zone, according to Formula 1 and Formula 2, the stiffness needs to be changed to adapt. If the stiffness is a constant value, it cannot adapt well to the needs of changing the excitation source and can only ensure that no resonance occurs under common working conditions; according to Formula 3, when approaching the resonance zone, 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, which includes: 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 be connected to the cooling module 3, and the first connecting plate 1 is provided with a protrusion 13 set in a gap with the main support cushion body 5, and the protrusion 13 is used to be connected to the cooling module 3, and the protrusion 13 can be deformed after being subjected to force and abut against the main support cushion body 5, so that the area of ​​the contact surface between the main support cushion body 5 and the first connecting plate 1 is increased.

[0053] It can be understood that the main support cushion body 5, second connecting plate 2, and first connecting plate 1 comprise the cooling module suspension's primary support structure. This structure isolates vibrations transmitted from the vehicle frame, accommodating and reducing the effects of additional stress on the cooling module caused by frame deformation. Furthermore, by adjusting the stiffness of the main support, resonance is avoided or mitigated, improving the cooling module's reliability and durability, and enhancing the overall vehicle ride comfort.

[0054] Furthermore, the second connecting plate 2 and the first connecting plate 1 are vulcanized into a whole. Figure 1 As shown, the vulcanized contact surface between the first connecting plate 1 and the main support cushion body 5 serves as a constrained surface, while the remaining free, open surfaces serve as free surfaces. Furthermore, the gap between the raised portion 13 of the first connecting plate 1 and the main support cushion body 5 forms a variable free surface. When the raised portion 13 deforms and presses downward to contact the main support cushion body 5, this variable free surface becomes a constrained surface, increasing the stiffness of the portion of the main support cushion body 5 originally below the variable free surface.

[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 this 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 deform and press downward, and come into contact with the main support cushion body 5, thereby changing the area of ​​the supporting surface between the main support cushion body 5 and the first connecting plate 1, thereby increasing the rigidity of the main support structure. In this application, the deformation of the protrusion 13 can switch the cooling module suspension device between the first state and the second state; wherein,

[0057] When the cooling module suspension device is in the first state, the first connecting plate 1 is not deformed, and the area of ​​the contact surface between the main support cushion body 5 and the first connecting plate 1 remains unchanged. When the cooling module suspension device is in the 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 contact 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. Therefore, 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 that are connected as one body. The second connecting plate 2 includes a second plate body 21 and a pin 22 that are 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 noting 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, thereby avoiding damage to the cooling module 3 due to excessive displacement under special circumstances.

[0061] In conjunction with the first aspect, in a preferred embodiment, a mounting groove is provided within 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 within the receiving cavity, wherein the stiffness adjustment component 6 can adjust 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 will be appreciated that, as described above, the first damping assembly 7 is used to adjust the damping ratio of the main support structure to ensure a reduced vibration amplitude. The stiffness adjustment assembly 6, in conjunction with the raised portion 13 in the above-described embodiment, adjusts the stiffness of the main support structure. In practice, either the stiffness adjustment assembly 6 or the first damping assembly 7 can be installed within the main support cushion body 5. Alternatively, both the stiffness adjustment assembly 6 and the first damping assembly 7 can be installed within the main support cushion body 5.

[0063] It's worth noting that the design of rubber shock-absorbing pads can be broadly categorized into two main principles for variable stiffness: one is a variable cross-section pad design, and the other is controlled by varying the free surface area of ​​the rubber. This application combines the variable cross-section pad design of the stiffness adjustment assembly 6 with the free surface area adjustment design formed by the deformable raised portion 13. This achieves variable stiffness across the entire range, broadening its adaptability.

[0064] In combination with the above specific implementation manner, as 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] The rotating part 61 is installed in the storage cavity, and the rotating part 61 can be rotated to abut or separate from the surface of the storage cavity; the driving member 62 is installed in the storage cavity, and the driving member 62 is connected to the second connecting plate 2. 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 to 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 understood that the elastic member 613 is always in a compressed state, eliminating any gap between the rotating plate 612 and the telescopic member 63, thereby preventing the impact noise caused by the gap. During use, the driver 62, which can be a pneumatic or hydraulic cylinder, acts as an actuator. The driver 62 pushes the telescopic member 63 to extend and retract, which in turn pushes the variable-angle rotating plate 612 to deflect. This changes the contact 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, as 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. A piston member 72 has one end connected to the first connecting plate 1 and the other end extending into and movable within the damping cylinder 71. The medium within the damping cylinder 71 can be oil or another medium (such as air). Preferably, a dust cover is provided on the piston member 72 to prevent the ingress of dust or impurities that could affect operation.

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

[0072] In some preferred embodiments, 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 is staggered with each other and connected by an auxiliary cushion 82, and the other end of the two auxiliary support rods 81 is used to connect to the cooling module 3 and the frame 4 respectively.

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

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

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

[0077] In some other preferred embodiments, Figure 7 As shown, the auxiliary support rod 81 is provided with a second damping assembly 9. Specifically, the second damping assembly 9 is provided in the extended support rod 811, which has a cavity therein for accommodating the second damping assembly 9. Similarly, an oil cylinder or an air cylinder can be used to partially move the second damping assembly 9 in the auxiliary cushion 82. A throttle 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 embodiment of the main support structure described above. 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, comprising: a cooling module suspension device, the cooling module suspension device comprising: 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 be connected to the cooling module 3, and the first connecting plate 1 is provided with a protrusion 13 set in a gap with the main support cushion body 5, and the protrusion 13 is used to be connected to the cooling module 3, and the protrusion 13 can be deformed after being subjected to force and abut against the main support cushion body 5, so that the area of ​​the contact surface between the main support cushion body 5 and the first connecting plate 1 is increased.

[0081] It can be understood that the main support cushion body 5, second connecting plate 2, and first connecting plate 1 comprise the cooling module suspension's primary support structure. This structure isolates vibrations transmitted from the vehicle frame, accommodating and reducing the effects of additional stress on the cooling module caused by frame deformation. Furthermore, by adjusting the stiffness of the main support, resonance is avoided or mitigated, improving the cooling module's reliability and durability, and enhancing the overall vehicle ride comfort.

[0082] Furthermore, the second connecting plate 2 and the first connecting plate 1 are vulcanized into a whole. Figure 1 As shown, the vulcanized contact surface between the first connecting plate 1 and the main support cushion body 5 serves as a constrained surface, while the remaining free, open surfaces serve as free surfaces. Furthermore, the gap between the raised portion 13 of the first connecting plate 1 and the main support cushion body 5 forms a variable free surface. When the raised portion 13 deforms and presses downward to contact the main support cushion body 5, this variable free surface becomes a constrained surface, increasing the stiffness of the portion of the main support cushion body 5 originally below the variable free surface.

[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 this 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 deform and press downward, and come into contact with the main support cushion body 5, thereby changing the area of ​​the supporting surface between the main support cushion body 5 and the first connecting plate 1, thereby increasing the rigidity of the main support structure. In this application, the deformation of the protrusion 13 can switch the cooling module suspension device between the first state and the second state; wherein,

[0085] When the cooling module suspension device is in the first state, the first connecting plate 1 is not deformed, and the area of ​​the contact surface between the main support cushion body 5 and the first connecting plate 1 remains unchanged. When the cooling module suspension device is in the 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 contact surface between the main support cushion body 5 and the first connecting plate 1 is increased.

[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. Therefore, 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 that are connected as one body. The second connecting plate 2 includes a second plate body 21 and a pin 22 that are 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.

[0088] It is worth noting 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, thereby avoiding damage to the cooling module 3 due to excessive displacement under special circumstances.

[0089] In conjunction with the first aspect, in a preferred embodiment, a mounting groove is provided within 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 within the receiving cavity, wherein the stiffness adjustment component 6 can adjust 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.

[0090] It will be appreciated that, as described above, the first damping assembly 7 is used to adjust the damping ratio of the main support structure to ensure a reduced vibration amplitude. The stiffness adjustment assembly 6, in conjunction with the raised portion 13 in the above-described embodiment, adjusts the stiffness of the main support structure. In practice, either the stiffness adjustment assembly 6 or the first damping assembly 7 can be installed within the main support cushion body 5. Alternatively, both the stiffness adjustment assembly 6 and the first damping assembly 7 can be installed within the main support cushion body 5.

[0091] It's worth noting that the design of rubber shock-absorbing pads can be broadly categorized into two main principles for variable stiffness: one is a variable cross-section pad design, and the other is controlled by varying the free surface area of ​​the rubber.

[0092] In combination with the above specific implementation manner, as 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,

[0093] The rotating part 61 is installed in the storage cavity, and the rotating part 61 can be rotated to abut or separate from the surface of the storage cavity; the driving member 62 is installed in the storage cavity, and the driving member 62 is connected to the second connecting plate 2. 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.

[0096] It is understood that the elastic member 613 is always in a compressed state, eliminating any gap between the rotating plate 612 and the telescopic member 63, thereby preventing the impact noise caused by the gap. During use, the driver 62, which can be a pneumatic or hydraulic cylinder, acts as an actuator. The driver 62 pushes the telescopic member 63 to extend and retract, which in turn pushes the variable-angle rotating plate 612 to deflect. This changes the contact area between the rotating plate 612 and the surface of the storage cavity, thereby actively changing the stiffness.

[0097] In combination with the above specific implementation manner, as Figure 2 As shown, in some specific embodiments, the first damping assembly 7 includes: a damping cylinder 71 and a piston 72; wherein,

[0098] The damping cylinder 71 is connected to the second connecting plate 2. A piston member 72 has one end connected to the first connecting plate 1 and the other end extending into and movable within the damping cylinder 71. The medium within the damping cylinder 71 can be oil or another medium (such as air). Preferably, a dust cover is provided on the piston member 72 to prevent the ingress of dust or impurities that could affect operation.

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

[0100] In some preferred embodiments, 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 is staggered with each other and connected by an auxiliary cushion 82, and the other end of the two auxiliary support rods 81 is used to connect to the cooling module 3 and the frame 4 respectively.

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

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

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

[0105] In some other preferred embodiments, Figure 7 As shown, the auxiliary support rod 81 is provided with a second damping assembly 9. Specifically, the second damping assembly 9 is provided in the extended support rod 811, which has a cavity therein for accommodating the second damping assembly 9. Similarly, an oil cylinder or an air cylinder can be used to partially move the second damping assembly 9 in the auxiliary cushion 82. A throttle 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 embodiment of the main support structure described above, and the auxiliary support rod 81 and the second damping assembly 9 can be made into an integral structure or a separate structure.

[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 no resonance occurs under common working conditions. Therefore, the stiffness of the main support structure needs to be changed 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 change, it will deform and press down, and come into contact with the main support cushion body, thereby changing the area of ​​the support surface between the main support cushion body and the first connecting plate, thereby increasing the stiffness of the main support structure.
