Detailed Implementation

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0036] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] The following is combined Figures 1-5 The vibration damping support device 10, suspension system 100 and vehicle 1000 according to embodiments of this application are described in detail.

[0038] Reference Figures 1-5 As shown, the vibration damping support device 10 according to the embodiment of this application may include a first pressure plate 1, a first elastic element 2 and a spring 4. The first pressure plate 1 is adapted to connect to the air supply unit 20 in the suspension system 100. A spring mounting space A is formed between the first elastic element 2 and the first pressure plate 1. The first elastic element 2 is adapted to connect to the vehicle body 300. The spring 4 is disposed in the spring mounting space A. One end of the spring 4 abuts against the first pressure plate 1, and the other end of the spring 4 abuts against the first elastic element 2.

[0039] The connection between the first elastic element 2 and the vehicle body 300 includes direct connection and indirect connection. For example, the first elastic element 2 is directly connected to the vehicle body 300, or the first elastic element 2 is indirectly connected to the vehicle body 300 through the mounting bracket 200. Indirect connection is also within the protection scope of this application.

[0040] In related technologies, springs require a separate mounting base for positioning and fixing, and the mounting base is fixed to the pressure plate via a connecting structure, resulting in a complex structure for the vibration damping support device. According to the embodiment of this application, the vibration damping support device 10 eliminates the need for a separate mounting base for fixing the spring 4 by placing the spring 4 within the spring mounting space A between the first elastic member 2 and the first pressure plate 1, thus simplifying the overall structure of the vibration damping support device 10.

[0041] The first pressure plate 1 can transmit torque.

[0042] Spring 4 is a compression spring, used to temporarily store the kinetic and potential energy generated by the vibration impact of the air supply unit 20 as its own elastic potential energy, preventing the impact energy from being directly transmitted to the vehicle body 300, and blocking or attenuating the transmission of vibration.

[0043] When the first elastic element 2 is compressed, it can undergo elastic deformation. Through the elastic deformation of the first elastic element 2 itself, it can further absorb and isolate the vibration energy attenuated by the spring 4. At the same time, when the first elastic element 2 is deformed, the molecular chains inside it rub against each other, and a part of the vibration energy is converted into heat energy and dissipated.

[0044] In some embodiments of this application, the first elastic member 2 may be an elastic material member such as a rubber member, a silicone member, a polyurethane member, or a foamed polypropylene member.

[0045] In actual installation, it can be as follows: Figures 1-5 As shown, the first pressure plate 1 is located above the first elastic member 2, and the air supply unit 20 is located below the first elastic member 2. Alternatively, the first pressure plate 1 can be located below the first elastic member 2, and the air supply unit 20 can be located above the first elastic member 2. For ease of description, the following will use the example of the first pressure plate 1 being located above the first elastic member 2 and the air supply unit 20 being located below the first elastic member 2.

[0046] Regarding the downward vibration impact generated by the air supply unit 20, since the air supply unit 20 is rigidly connected to the first pressure plate 1, the air supply unit 20 will drive the first pressure plate 1 to impact downwards. Thus, the impact of the first pressure plate 1 will first pass through the spring 4, then through the first elastic element 2, and finally be transmitted to the vehicle body 300. Compared to the related technology where the first elastic element is directly connected to the air supply unit, this application first connects the first pressure plate 1 to the air supply unit 20. The first pressure plate 1 transmits the impact force of the air supply unit 20 to the first elastic element 2 through the spring 4, which can improve the uniformity of the pressure on the first elastic element 2 and help extend the service life of the first elastic element 2.

[0047] In some embodiments of this application, the first pressure plate 1 is a metal plate, such as an aluminum plate or a steel plate. The first pressure plate 1 has a certain degree of toughness, can undergo a certain degree of elastic deformation, and is not easily damaged.

[0048] In some embodiments of this application, reference is made to Figures 1-5 As shown, the first pressure plate 1 and / or the first elastic element 2 include a limiting structure 3. The spring 4 cooperates with the limiting structure 3, and the limiting structure 3 is used to limit the radial position of the spring 4. In other words, the limiting structure 3 is integrated on at least one of the first pressure plate 1 and the first elastic element 2, thereby eliminating the need for a separate mounting base, reducing the number of parts, saving assembly time, and reducing the overall weight.

[0049] In some embodiments, only the first pressure plate 1 includes the limiting structure 3.

[0050] In some embodiments, only the first elastic member 2 includes the limiting structure 3.

[0051] In some embodiments, both the first pressure plate 1 and the first elastic member 2 include a limiting structure 3.

[0052] In related technologies, springs require a separate mounting base for positioning and fixing, and the mounting base is fixed to the pressure plate via a connecting structure, resulting in a complex structure for the vibration damping support device. According to the embodiment of this application, the vibration damping support device 10 integrates the limiting structure 3 onto the first pressure plate 1 and / or the first elastic member 2, eliminating the need for a separate mounting base for fixing the spring 4, thus simplifying the overall structure of the vibration damping support device 10.

[0053] In some embodiments of this application, reference is made to Figure 1 , Figure 3 As shown, the limiting structure 3 includes at least one first limiting structure 31, which is formed on the first pressure plate 1. The first limiting structure 31 is used to limit the radial position of one end of the spring 4. The number of first limiting structures 31 can be one or more, for example, in... Figure 1 In the example, the number of first limiting structures 31 is four.

[0054] In some embodiments, the first pressure plate 1 protrudes partially toward the spring mounting space A to form a first limiting structure 31.

[0055] In some embodiments of this application, reference is made to Figure 1 , Figure 3 As shown, the limiting structure 3 includes at least one second limiting structure 32, which is formed on the first elastic member 2. The second limiting structure 32 is used to limit the radial position of the other end of the spring 4. The number of second limiting structures 32 can be one or more, for example, in... Figure 1In the example, the number of second limiting structures 32 is four.

[0056] In some embodiments, the first elastic member 2 protrudes partially toward the spring mounting space A to form the second limiting structure 32.

[0057] In some embodiments of this application, the first limiting structure 31 and the second limiting structure 32 are at least partially opposite to each other in the axial direction of the spring 4. Both ends of the spring 4 are limited in the axial direction, thereby making the spring 4 less prone to displacement, and the spring 4 can better absorb impact energy when the air supply unit 20 moves up and down.

[0058] In some embodiments of this application, at least one of the first limiting structure 31 and the second limiting structure 32 includes a boss that protrudes toward the spring mounting space A and extends into the cavity inside the spring 4. For example Figure 3 The two first limiting structures 31 shown are first limiting structure one 31a and first limiting structure three 31c, both of which are bosses.

[0059] The boss serves to limit the radial movement of spring 4 and also facilitates the positioning and fixation of spring 4 during installation. The design of the boss can improve the structural strength of the corresponding structure.

[0060] In some embodiments of this application, the diameter of the boss is slightly smaller than the inner diameter of the spring 4, thereby facilitating the fitting of the spring 4 onto the boss.

[0061] In some embodiments of this application, at least one of the first limiting structure 31 and the second limiting structure 32 includes a groove recessed in a direction away from the spring mounting space A, and the end of the spring 4 is located within the groove. For example Figure 3 One of the two second limiting structures 32 shown is a boss, and the other is a groove. The two second limiting structures 32 are second limiting structure one 32a and second limiting structure three 32c. Second limiting structure one 32a is a boss, and second limiting structure three 32c is a groove.

[0062] The groove serves to limit the radial movement of spring 4 and also facilitates the positioning and fixation of spring 4 during installation. The groove design enhances the structural strength of the corresponding structure.

[0063] In specific embodiments, the boss can take many forms, such as a single-stage boss as shown in the first limiting structure 31a and the first limiting structure 31c, or a two-stage boss as shown in the second limiting structure 32a.

[0064] In some embodiments of this application, the outer diameter of the spring 4 is smaller than the inner diameter of the groove. As the compression of the spring 4 increases, the difference between the outer diameter of the spring 4 and the inner diameter of the groove gradually decreases. Specifically, the outer diameter of the spring 4 is smaller than the inner diameter of the groove, thus providing space for the compression deformation of the spring 4. The groove includes a bottom wall and an inner side wall, which are connected to the bottom wall. One axial end of the spring 4 abuts against the bottom wall of the groove. As the compression of the spring 4 increases, the outer diameter of the spring 4 also increases, causing the outer periphery of the spring 4 to gradually approach the inner side wall of the groove. When the outer periphery of the spring 4 abuts against the inner side wall of the groove, the end of the spring 4 is restricted by the inner side wall of the groove, so that the outer diameter of the end of the spring 4 no longer increases.

[0065] In related technologies, both ends of the spring 4 require rubber pads or mounting bases to limit its radial movement, which increases the number of parts and cost. The vibration damping support device 10 of this application only requires the first elastic element 2 on one side to cooperate with the optimized design of the first pressure plate 1 to limit the radial movement of the upper and lower ends of the spring 4 while damping vibration. At the same time, by providing a limiting structure 3 on the first pressure plate 1, the strength of the first pressure plate 1 can also be improved.

[0066] In some embodiments of this application, reference is made to Figure 1 and Figure 3 As shown, the first elastic member 2 includes a first body 21 and a first tooth 22. The first body 21 is adapted to connect to the vehicle body 300, and the first tooth 22 is connected to the first body 21. The first pressure plate 1 can squeeze the first tooth 22 when it is impacted.

[0067] The first tooth 22 is located on the side of the first body 21 facing the first pressure plate 1. The first tooth 22 is constructed as a tooth-shaped protrusion that protrudes in the direction of the first pressure plate 1. In a static state, there is a gap between the first tooth 22 and the first pressure plate 1. When the air supply unit 20 generates a downward vibration impact, the first pressure plate 1 moves downward and first compresses the spring 4. The spring 4 then impacts the first body 21, for example, impacting the second limiting structure 32 on the first body 21. When the spring 4 is compressed to near the limit compression amount, the first pressure plate 1 will contact the first tooth 22, which improves the overall stiffness and absorbs and dampens the vibration, preventing the spring 4 from losing its vibration isolation effect when compressed to the limit position.

[0068] In some embodiments of this application, the vibration damping support device 10 further includes a fastener 8, which passes through the first pressure plate 1 and the first elastic member 2 and is adapted to connect to the air supply unit 20. By setting the fastener 8, the connection and fixation between the first pressure plate 1, the first elastic member 2 and the air supply unit 20 are achieved.

[0069] For example, fastener 8 can be a bolt, rivet, etc.

[0070] In some embodiments of this application, the vibration damping support device 10 further includes a second elastic element 6, which is disposed on the side of the first elastic element 2 opposite to the first pressure plate 1. A fastener 8 passes through the first pressure plate 1, the first elastic element 2, and the second elastic element 6 and is adapted to connect to the air supply unit 20. By providing the fastener 8, the connection and fixation between the first pressure plate 1, the first elastic element 2, the second elastic element 6, and the air supply unit 20 are achieved.

[0071] A bracket mounting space is provided between the first elastic member 2 and the second elastic member 6. The mounting bracket 200 installed on the vehicle body 300 is located at least partially within the bracket mounting space. In other words, the bracket mounting space is used to install the mounting bracket 200.

[0072] In some embodiments of this application, the second elastic member 6 abuts against the first elastic member 2. When one of the first elastic member 2 and the second elastic member 6 is impacted by the other, the impact force can be transmitted and absorbed.

[0073] When the second elastic element 6 is compressed, it can undergo elastic deformation. Through the elastic deformation of the second elastic element 6 itself, it can further absorb and isolate the vibration energy attenuated by the spring 4. At the same time, when the second elastic element 6 is deformed, the molecular chains inside it rub against each other, and a part of the vibration energy is converted into heat energy and dissipated.

[0074] In some embodiments of this application, the second elastic member 6 may be an elastic material member such as a rubber member, a silicone member, a polyurethane member, or a foamed polypropylene member.

[0075] The second elastic element 6 and the first elastic element 2 can be made of the same material or different materials.

[0076] In some embodiments of this application, the vibration damping support device 10 further includes a second pressure plate 7, which is disposed on the side of the second elastic member 6 opposite to the first elastic member 2. The second pressure plate 7 abuts against the second elastic member 6. A fastener 8 passes through the first pressure plate 1, the first elastic member 2, the second elastic member 6, and the second pressure plate 7 and is adapted to connect to the air supply unit 20. By providing the fastener 8, the connection and fixation between the first pressure plate 1, the first elastic member 2, the second elastic member 6, and the air supply unit 20 are achieved.

[0077] In some embodiments of this application, the vibration damping support device 10 further includes a bushing 5. One end of the bushing 5 abuts against the first pressure plate 1, and the other end of the bushing 5 abuts against the second pressure plate 7. The first elastic member 2 has a first through hole 23, and the second elastic member 6 has a second through hole 63. The bushing 5 passes through the first through hole 23 and the second through hole 63. The bushing 5 has a bushing hole inside, and the fastener 8 passes through the bushing hole. The fastener 8 rigidly connects the air supply unit 20, the first pressure plate 1, the second pressure plate 7, and the bushing 5. Specifically, the bushing 5 can improve the connection strength of the fastener 8, and after the fastener 8 is tightened, it presses the first pressure plate 1 and the second pressure plate 7 at both ends, rigidly connecting the first pressure plate 1 and the second pressure plate 7 to the air supply unit 20, thereby achieving the purpose of torque transmission.

[0078] In some embodiments of this application, a first through hole 23 may be provided on the second limiting structure 32. The first through hole 23 allows the fastener 8 and the bushing 5 to pass through, so that the limiting position of the spring 4 and the fastening position of the fastener 8 at least partially overlap at that location. (Refer to...) Figure 3 As shown, the second limiting structure 32a is provided with a first through hole 23.

[0079] In some embodiments of this application, the first elastic member 2 is adapted to be connected to the vehicle body 300 via the mounting bracket 200. The first elastic member 2 and the vehicle body 300 are indirectly connected via the mounting bracket 200. The second elastic member 6 includes: a second body 61 and a second tooth 62. The second pressure plate 7 abuts against the second body 61. The second tooth 62 is connected to the second body 61. When the second tooth 62 is subjected to impact, it can squeeze the mounting bracket 200.

[0080] The second tooth 62 is located on the side of the second body 61 facing the mounting bracket 200. The second tooth 62 is constructed as a tooth-shaped protrusion that protrudes in the direction of the mounting bracket 200. In a static state, there is a gap between the second tooth 62 and the mounting bracket 200. When the air supply unit 20 generates an upward vibration impact, the second pressure plate 7 moves upward. Due to the weight of the air supply unit 20 after installation, the spring 4 will have a certain amount of compression. After the upward impact overcomes the gravity of the air supply unit 20, the air supply unit 20 will first move upward to make the spring 4 rebound, and then the second tooth 62 will contact the mounting bracket 200. The vibration transmitted to the mounting bracket 200 is absorbed and attenuated by the elastic deformation of the second tooth 62.

[0081] The mounting bracket 200 is used to fix the air supply unit 20 to the vehicle body 300. The second elastic member 6 is located between the mounting bracket 200 and the second pressure plate 7.

[0082] Spring 4 can temporarily store the kinetic and potential energy generated by vibration and impact as its own elastic potential energy, preventing the impact energy from being directly transmitted to the mounting bracket 200, thus blocking or attenuating the transmission of vibration.

[0083] The upward vibration impact generated by the air supply unit 20 is caused by the rigid connection between the air supply unit 20 and the second pressure plate 7. The air supply unit 20 will drive the second pressure plate 7 to impact upward. The impact will be absorbed and damped by the second elastic element 6 and then transmitted to the mounting bracket 200.

[0084] Compared to the related technologies where the second elastic element is directly connected to the air supply unit, this application first connects the second pressure plate 7 to the air supply unit 20. The second pressure plate 7 transmits the impact force of the air supply unit 20 to the second elastic element 6, which can improve the uniformity of the pressure on the second elastic element 6 and help extend the service life of the second elastic element 6.

[0085] In some embodiments of this application, the second pressure plate 7 is a metal plate, such as an aluminum plate or a steel plate. The second pressure plate 7 has a certain degree of toughness, can undergo a certain degree of elastic deformation, and is not easily damaged.

[0086] The vibration damping support device 10 is connected to the air supply unit 20 and the mounting bracket 200 respectively. The vibration damping support device 10 according to this application can be used to connect and fix the air supply unit 20 to the mounting bracket 200, and attenuate the vibration transmitted from the air supply unit 20 to the mounting bracket 200.

[0087] In some embodiments of this application, there are multiple springs 4, which are spaced apart. Therefore, multiple springs 4 can absorb impact energy simultaneously, which helps to improve energy absorption efficiency.

[0088] exist Figure 1 In the example, there are four springs 4, and four first limiting structures 31 and four second limiting structures 32. The two ends of the springs 4 are limited by the corresponding first limiting structure 31 and the corresponding second limiting structure 32.

[0089] In an embodiment not shown in the figure, the number of springs 4 can be one, two, three, five or more. The number of the first limiting structure 31 and the second limiting structure 32 are equal to the number of springs 4, and the positions of the first limiting structure 31 and the second limiting structure 32 also correspond one-to-one with the positions of the springs 4.

[0090] In some embodiments of this application, there are multiple fasteners 8, with at least one fastener 8 passing through the spring 4.

[0091] Reference Figure 2 and Figure 3There are four springs 4: spring 4a, spring 4b, spring 4c, and spring 4d. There are three fasteners 8: fastener 8a, fastener 8b, and fastener 8c. Spring 4a is coaxially mounted with fastener 8a, and fastener 8a passes through spring 4a. First limiting structure 31a and second limiting structure 32a can respectively limit the radial movement of the upper and lower ends of spring 4a. Spring 4b is coaxially mounted with fastener 8b, and fastener 8b passes through spring 4b. First limiting structure 31c and second limiting structure 32c can respectively limit the radial movement of the upper and lower ends of spring 4c. Fastener 8c is not coaxial with spring 4c, and fastener 8c is not coaxial with spring 4d.

[0092] The spring 4 does not necessarily need to be coaxial with the fastener 8. In some cases, the spring 4 and fastener 8 are not coaxial, which improves the stability of the spring 4 and prevents entanglement and interference between the spring 4 and fastener 8 under load. (Refer to...) Figure 2 and Figure 4 The first spring 4a is coaxially arranged with the first fastener 8a, the second spring 4b is coaxially arranged with the second fastener 8b, the third spring 4c and the fourth spring 4d are installed separately, and the third fastener 8c is installed separately.

[0093] In some embodiments not shown in the figures, the fastener 8 does not need to pass through the spring 4. The fastener 8 and the spring 4 are staggered, and neither the fastener 8 nor the spring 4 is coaxial.

[0094] In some embodiments of this application, the limiting structure 3 includes: a first limiting structure 31, which is formed on the first pressure plate 1. The first limiting structure 31 is used to limit the radial position of one end of the spring 4. At least one first limiting structure 31 is provided with a third through hole 11, and the second pressure plate 7 is provided with a fourth through hole 71. The fastener 8 passes through the third through hole 11 and the fourth through hole 71.

[0095] In some embodiments of this application, there are multiple first limiting structures 31 and second limiting structures 32. At least one first limiting structure 31 is provided with a third through hole 11, and at least one second limiting structure 32 is provided with a fourth through hole 71.

The fastener 8 is a bolt and includes a head 81 and a rod 82. The head 81 is embedded in the side of the boss away from the spring mounting space A. A third through hole 11 is formed on the boss. The rod 82 is connected to the head 81 and passes through the third through hole 11 and the fourth through hole 71. The side of the boss away from the spring mounting space A is a recess, and the head 81 is embedded in the recess, thereby saving the overall height of the vibration damping support device 10. The third through hole 11 is located in the recess and is used for the rod 82 to pass through.

[0097] In some embodiments of this application, reference is made to Figure 1 , Figure 3 As shown, the first pressure plate 1 has a third through hole 11, and the second pressure plate 7 has a fourth through hole 71. The fastener 8 passes through the third through hole 11 and the fourth through hole 71. The end of the fastener 8 extending from the fourth through hole 71 has a threaded section 83, which is suitable for connecting to the air supply unit 20. Specifically, the air supply unit 20 can have a threaded hole, and the threaded section 83 is screwed into the threaded hole to achieve the connection and fixation of the bolt to the air supply unit 20.

[0098] In some embodiments of this application, the second pressure plate 7 has the same structure as the first pressure plate 1. This makes the second pressure plate 7 compatible with the first pressure plate 1 in a common design, requiring only one set of molds for production, thus saving production costs.

[0099] In some embodiments not shown in the figure, the structure of the second pressure plate 7 may be different from that of the first pressure plate 1.

[0100] Reference Figure 5 As shown, the suspension system 100 according to the second aspect of this application includes an air supply unit 20 and a vibration damping support device 10 as described above. The air supply unit 20 is connected to the first pressure plate 1.

[0101] In some embodiments of this application, there are multiple springs 4, and the multiple springs 4 are arranged at intervals on the first pressure plate 1 around the center of mass of the air supply unit 20. The arrangement of the springs 4 can surround the center of mass and the center of motion of the air supply unit 20. The center of mass of the air supply unit 20 can be directly measured by an instrument, or it can be obtained by three-dimensional modeling of the air supply unit 20 in three-dimensional software and calculating it using the software, or it can be obtained by experimental methods.

[0102] According to the embodiment of this application, the suspension system 100 has a simple overall structure because the spring 4 is placed in the spring mounting space A between the first elastic member 2 and the first pressure plate 1, which eliminates the need for a separate mounting seat for fixing the spring 4.

[0103] Reference Figure 5 As shown, the vehicle 1000 according to the third aspect embodiment of this application includes a body 300, a mounting bracket 200 and a suspension system 100 of the above embodiment, wherein a first elastic member 2 is mounted on the mounting bracket 200 and the mounting bracket 200 is mounted on the body 300.

[0104] According to the embodiment of this application, the vehicle 1000 has a simple overall structure because the spring 4 is placed in the spring mounting space A between the first elastic member 2 and the first pressure plate 1, which eliminates the need for a separate mounting seat for fixing the spring 4.
