DETAILED DESCRIPTION

[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] The air spring and vehicle disclosed herein are described in detail below through specific embodiments:

[0040] 1 to 11 , an air spring and a vehicle provided by one embodiment of the present invention include an air spring body 1 and an elastic structure.

[0041] Among them, the top of the air spring body 1 is provided with a first mounting seat 2 for connecting to the frame, and the bottom of the air spring body 1 is provided with a second mounting seat 4 for connecting to the suspension, that is, the top of the air spring body 1 is connected to the frame through the first mounting seat 2, and the bottom of the air spring body 1 is connected to the suspension through the second mounting seat 4. The vibration generated when the wheel is running is transmitted to the body through the suspension, air spring, and frame in sequence, and the air spring body 1 is used to buffer the vibration to improve the comfort of the entire vehicle.

[0042] Furthermore, the elastic structure includes a first elastic member 3 and / or a second elastic member 5, that is, the elastic structure includes one of the first elastic member 3 and the second elastic member 5, or includes both the first elastic member 3 and the second elastic member 5. The first elastic member 3 is disposed on the top surface of the first mounting seat 2 away from the air spring body 1, and the second elastic member 5 is disposed on the bottom surface of the second mounting seat 4 away from the air spring body 1. In other words, the first elastic member 3 can be disposed between the first mounting seat 2 and the vehicle frame, and the first elastic member 3 can be used to buffer vibrations between the first mounting seat 2 and the vehicle frame. The second elastic member 5 can be disposed between the second mounting seat 4 and the suspension, and the second elastic member 5 can be used to buffer vibrations between the second mounting seat 4 and the suspension. Compared to a solution in which the first mounting seat 2 is directly rigidly connected to the vehicle frame and the second mounting seat 4 is directly rigidly connected to the suspension, the elastic structure can further improve the vibration isolation performance of the entire vehicle and can also avoid the problem of abnormal noise between the air spring, the frame, and the suspension caused by the flatness of the vehicle body and the friction between them under extreme operating conditions.

[0043] It can be understood that when the air spring is installed between the frame and the suspension, the first elastic member 3 is arranged between the first mounting seat 2 and the frame to buffer the vibration between the first mounting seat 2 and the frame, and the second elastic member 5 is arranged between the second mounting seat 4 and the suspension to buffer the vibration between the second mounting seat 4 and the suspension. Such an arrangement can improve the vibration isolation performance of the vehicle.

[0044] In some embodiments, as shown in Figures 3 to 6, the top surface of the first mounting seat 2 away from the air spring body 1 forms a first plane 21, and the first elastic member 3 is adapted and arranged in a close fit with the first plane 21. It can be understood that the top surface of the first mounting seat 2 forms the first plane 21, and the first elastic member 3 and the first plane 21 are in abutment contact, so that the first elastic member 3 and the first plane 21 can be evenly stressed, thereby buffering the vibration from the wheel. Specifically, the shape of the first elastic member 3 is adapted to the shape of the first plane 21, so that the first elastic member 3 can be evenly stressed.

[0045] A second honeycomb structure 22 is formed on the first plane 21, recessed toward the air spring body 1. Specifically, the proportion of the area of ​​the second honeycomb structure 22 to the area of ​​the first plane 21 can be set according to actual needs and is not limited in this disclosure. As long as the first plane 21 is formed on the top surface of the first mounting seat 2 so that the first plane 21 and the first elastic member 3 form an abutting surface and the vibration force from the wheel is evenly distributed to the first elastic member 3, the requirements are met.

[0046] Furthermore, a bearing is provided on the bottom surface of the first mounting seat 2 facing the air spring body 1, which is rotatably connected to the air spring body 1 through the bearing, so that the suspension and the wheel can be driven to rotate relative to the frame through the air spring body 1, thereby enabling the wheel to adapt to various road conditions and improve the driving stability of the vehicle.

[0047] As shown in Figures 7 to 11, the bottom surface of the second mounting seat 4, which is away from the air spring body 1, forms a second plane 41. The second elastic member 5 is adapted to and fitted with the second plane 41. In other words, the top surface of the second mounting seat 4 forms the second plane 41. The second elastic member 5 and the second plane 41 are in contact with each other, so that the second elastic member 5 and the second plane 41 can be evenly stressed, thereby buffering the vibration from the wheel. Specifically, the shape of the second elastic member 5 is adapted to the shape of the second plane 41, so that the second elastic member 5 can be evenly stressed.

[0048] Of course, it should be noted that the shape of the first elastic member 3 and the shape of the second elastic member 5 can also be set to other shapes, and the present disclosure does not limit this, as long as the first elastic member 3 can be set between the first mounting seat 2 and the frame and buffer the vibration between the first mounting seat 2 and the frame, and the second elastic member 5 can be set between the second mounting seat 4 and the suspension and buffer the vibration between the second mounting seat 4 and the suspension.

[0049] Furthermore, a first honeycomb structure 42 is formed on the top surface of the second mounting seat 4 facing the air spring body 1. It will be appreciated that the second plane 41 and the first honeycomb structure 42 are formed on the bottom and top surfaces of the second mounting seat 4, respectively. This arrangement allows the second plane 41 to achieve surface contact with the second elastic member 5, thereby ensuring a sufficient force-bearing area, dispersing vibration forces, and ensuring the vehicle's vibration isolation performance.

[0050] Of course, a first honeycomb structure 42 may also be provided on the second plane 41, and this disclosure does not impose any restrictions thereon. This arrangement is sufficient as long as the second plane 41 and the second elastic member 5 are in surface contact, thereby ensuring vehicle vibration isolation performance. Specifically, this disclosure does not impose any restrictions on the design area of ​​the first honeycomb structure 42, as long as sufficient contact area is ensured between the second plane 41 and the second elastic member 5 to ensure vibration damping.

[0051] In some embodiments, the first elastic member 3 is detachably connected to the top surface of the first mounting seat 2 away from the air spring body 1, and the second elastic member 5 is detachably connected to the bottom surface of the second mounting seat 4 away from the air spring body 1. Specifically, the first elastic member 3 and the second elastic member 5 can be connected to the first mounting seat 2 and the second mounting seat 4 via a snap-fit ​​structure, so that the first elastic member 3 and the second elastic member 5 can be replaced in a timely manner after being worn during use, facilitating maintenance.

[0052] Of course, it should be noted that the first elastic member 3 and the second elastic member 5 can also be fixed to the first mounting seat 2 and the second mounting seat 4 by other fixing methods such as bonding, so that the first elastic member 3 and the first mounting seat 2, and the second elastic member 5 and the second mounting seat 4 can be stably connected. The present disclosure does not limit this. As long as the first elastic member 3 can be fixed to the first mounting seat 2 and the second elastic member 5 can be fixed to the second mounting seat 4, the vibration isolation performance of the vehicle can be guaranteed.

[0053] As shown in FIG3 , the first mounting base 2 is provided with a first locating pin 23 protruding from the top surface of the first mounting base 2. The first locating pin 23 is used to engage with the vehicle frame. It is understood that the vehicle frame is provided with a first locating hole, and the first locating pin 23 is inserted into the first locating hole to achieve the connection between the first mounting base 2 and the vehicle frame. Specifically, the number of the first locating pins 23 can be one or more, and this disclosure is not limited to this. As long as the number of the first locating holes is the same as the number of the first locating pins 23, the connection between the first mounting base 2 and the vehicle frame can be achieved.

[0054] Furthermore, the first elastic member 3 is provided with a first insertion hole 31, and the first positioning pin 23 is passed through the first insertion hole 31. Specifically, the number of the first insertion holes 31 is the same as the number of the first positioning pins 23, so that the first positioning pin 23 can pass through the first elastic member 3 and be plugged into the first positioning hole on the frame.

[0055] As shown in FIG8 , the second mounting base 4 is provided with a second locating pin 43 protruding from the bottom surface of the second mounting base 4. The second locating pin 43 is used to engage with the suspension. It is understood that the suspension is provided with a second locating hole, and the second locating pin 43 is inserted into the second locating hole to achieve the connection between the second mounting base 4 and the suspension. Specifically, the number of second locating pins 43 can be one or more, and this disclosure does not limit this. As long as the number of second locating holes is the same as the number of second locating pins 43, the connection between the second mounting base 4 and the suspension can be achieved.

[0056] Specifically, the second elastic member 5 is provided with a second insertion hole 51, and the second positioning pin 43 is passed through the second insertion hole 51. Furthermore, the number of the second insertion holes 51 is the same as the number of the second positioning pins 43, so that the second positioning pins 43 can pass through the second elastic member 5 and be plugged into the second positioning hole on the suspension.

[0057] Continuing with FIG8 , a positioning protrusion 431 is provided on the side wall of the second positioning pin 43. In a specific implementation, the second positioning hole on the suspension matches the shape of the first positioning pin 23 and the positioning protrusion 431 to prevent the second positioning pin 43 from driving the air spring body 1 to rotate relative to the suspension. At the same time, the second insertion hole 51 on the second elastic member 5 matches the shape of the first positioning pin 23 and the positioning protrusion 431 to enable the second positioning pin 43 to be inserted into the second insertion hole 51. Specifically, the positioning protrusion 431 is provided by the arched side wall of the second positioning pin 43 to prevent rotation when the second positioning pin 43 is inserted into the second positioning hole, thereby ensuring a stable connection.

[0058] In specific implementation, the first positioning pin 23 and the first plug-in hole 31 are interference fit, and the second positioning pin 43 and the second plug-in hole 51 are interference fit. With this arrangement, the first elastic member 3 can be sleeved on the first positioning pin 23, and the second elastic member 5 can be sleeved on the second positioning pin 43, and then the first elastic member 3 can be fixed on the top surface of the first mounting seat 2, and the second elastic member 5 can be fixed on the bottom surface of the second mounting seat 4. With this arrangement, the first elastic member 3 and the second elastic member 5 can be fixed correspondingly on the first mounting seat 2 and the second mounting seat 4 without additional gluing or setting of a snap-fit ​​structure. After the first elastic member 3 or the second elastic member 5 is worn, it can be replaced at any time.

[0059] In some embodiments, as shown in FIG10 , an air outlet 44 is provided on the bottom surface of the second mounting base 4 away from the air spring body 1, and an exhaust groove 52 is provided on the second elastic member 5. The exhaust groove 52 is provided corresponding to the air outlet 44 so that when the vehicle is driving, gas leaking from the air spring can be discharged outward through the air outlet 44 and the exhaust groove 52. In specific implementation, the number of the air outlet 44 and the exhaust groove 52 can be specifically set according to actual needs, and this disclosure does not limit this, as long as the positions of the air outlet 44 and the exhaust groove 52 are set in a one-to-one correspondence.

[0060] In a specific implementation, the first elastic member 3 is an elastic gasket, and the second elastic member 5 is an elastic gasket. In other words, the first elastic member 3 and the second elastic member 5 are both sheet-like structures capable of elastic deformation to buffer vibrations, and the surfaces of the first elastic member 3 and the second elastic member 5 are both formed into planar structures. This configuration enables abutment surface contact to be formed between the first elastic member 3 and the top surface of the first mounting seat 2, and between the first elastic member 3 and the vehicle frame, and also enables abutment surface contact to be formed between the second elastic member 5 and the bottom surface of the second mounting seat 4, and between the second elastic member 5 and the suspension, so that the first elastic member 3 and the second elastic member 5 are subjected to uniform force, thereby improving the vehicle's vibration isolation performance.

[0061] Of course, it should be noted that the first elastic member 3 and the second elastic member 5 can also be elastic members of other shapes, and the present disclosure does not limit this, as long as the first elastic member 3 and the second elastic member 5 can be subjected to uniform force and the buffering effect between the first mounting seat 2 and the frame, and between the second mounting seat 4 and the suspension is guaranteed.

[0062] Specifically, the thickness of the first elastic member 3 is between 2 mm and 4 mm. It is understood that the thickness of the first elastic member 3 is at least 2 mm to ensure that the first elastic member 3 has sufficient cushioning capacity. At the same time, the thickness of the first elastic member 3 should not be too large to avoid occupying excessive space, thereby maintaining a compact vehicle structure. The height of the first locating pin 23 protruding from the first elastic member 3 is greater than or equal to 17 mm. As shown in Figure 6, the height a of the first locating pin 23 protruding from the first elastic member 3 is greater than or equal to 17 mm. This arrangement ensures the connection strength between the first locating pin 23 and the vehicle frame.

[0063] The thickness of the second elastic member 5 is between 2 mm and 10 mm. In other words, the thickness of the second elastic member 5 is at least 2 mm to ensure sufficient cushioning capacity. At the same time, the thickness of the second elastic member 5 should not be too large to avoid occupying excessive space, thereby maintaining a compact vehicle structure. The height of the second locating pin 43 protruding from the second elastic member 5 is greater than or equal to 30 mm. As shown in Figure 11 , the height b of the second locating pin 43 protruding from the second elastic member 5 is greater than or equal to 17 mm. This ensures a stable connection between the second locating pin 43 and the suspension bracket, enhancing the vehicle's structural strength.

[0064] It can be understood that the second elastic member 5 is closer to the wheel than the first elastic member 3, so that the vibration from the wheel will first pass through the second elastic member 5 and then pass through the first elastic member 3 to buffer the vibration. The thickness of the second elastic member 5 can be appropriately increased to enhance the buffering capacity of the second elastic member 5. In this way, in order to make the structure of the vehicle more compact, while ensuring the buffering capacity, the thickness of the first elastic member 3 can be appropriately thinned. Specifically, the thickness of the first elastic member 3 and the thickness of the second elastic member 5 can be set according to actual needs.

[0065] The first elastic member 3 and the second elastic member 5 are formed from a polyurethane material or a rubber material by foaming or vulcanization. Of course, it should be noted that the first elastic member 3 and the second elastic member 5 can also be made from other materials and in other ways, and this disclosure is not limited to this, as long as the first elastic member 3 and the second elastic member 5 can buffer the vibration between the first mounting seat 2 and the frame, and between the second mounting seat 4 and the suspension.

[0066] In some embodiments, the top surface of the first mounting seat 2, which is away from the air spring body 1, is formed as an inclined plane, so that the inclined plane is arranged in abutment with the vehicle frame when the air spring is arranged at an angle. It is understood that when the air spring provided by the present disclosure is installed on a vehicle, the air spring is arranged at an angle, and the top surface of the first mounting seat 2, which is away from the air spring body 1, is formed as an inclined plane, and the inclined plane is arranged in abutment with the vehicle frame and is arranged horizontally, so that abutting surface contact is formed between the first elastic member 3 and the top surface of the first mounting seat 2, and between the first elastic member 3 and the vehicle frame, so that vibration between the air spring body 1 and the vehicle frame can be buffered by the first elastic member 3.

[0067] Furthermore, the bottom surface of the second mounting seat 4 away from the air spring body 1 forms a surface that is adapted to the surface of the suspension, so as to form abutment surface contact between the second elastic member 5 and the bottom surface of the second mounting seat 4, and between the second elastic member 5 and the suspension, so that the vibration between the suspension and the air spring body 1 can be buffered by the second elastic member 5.

[0068] In a specific implementation, the first mounting seat 2 is an injection-molded plastic seat and is fixedly connected to the top of the air spring body 1, and the second mounting seat 4 is an injection-molded plastic seat and is fixedly connected to the bottom of the air spring body 1. Of course, it should be noted that the first mounting seat 2 and the second mounting seat 4 can also be an integrated structure made of other materials, and this disclosure is not limited to this. As long as they can be fixed to the air spring body 1 and connected to the vehicle frame through the first mounting seat 2 and connected to the suspension through the second mounting seat 4, they will be sufficient.

[0069] It should be noted that the second honeycomb structure 22 on the first mounting seat 2 can also be formed into an integral structure with the first mounting seat 2 through injection molding, and the first honeycomb structure 42 on the second mounting seat 4 can also be formed into an integral structure with the second mounting seat 4 through injection molding. The second honeycomb structure 22 and the first honeycomb structure 42 can prevent the first mounting seat 2 and the second mounting seat 4 from being deformed during the injection molding process, thereby ensuring the structural strength of the first mounting seat 2 and the second mounting seat 4 and ensuring the service life of the air spring.

[0070] Other embodiments of the present disclosure provide a vehicle, including a frame, a suspension, and an air spring as described in any of the above embodiments, wherein a first mounting seat 2 is connected to the frame, and a first elastic member 3 is arranged between the first mounting seat 2 and the frame to buffer the vibration between the first mounting seat 2 and the frame, a second mounting seat 4 is connected to the suspension, and a second elastic member 5 is arranged between the second mounting seat 4 and the suspension to buffer the vibration between the second mounting seat 4 and the suspension, thereby improving the vibration isolation performance of the vehicle through the first elastic member 3 and / or the second elastic member 5.
