Technical Field

[0001] The present application belongs to the field of buffer technology, and in particular relates to a buffer structure, a suspension and a vehicle. Background Art

[0002] With the development of industrial level, vehicle manufacturing technology is constantly improving, and users' requirements for vehicles are also constantly improving, which is mainly reflected in the continuous improvement of users' requirements for vehicle ride comfort and handling stability. Therefore, designers can balance the ride comfort and handling stability of the vehicle to a certain extent by setting a suspension structure on the vehicle and calculating the stiffness of the spring and the damping coefficient of the shock absorber of the suspension structure through reasonable matching. However, the load that ordinary springs can bear is limited, and the adjustment accuracy of ordinary springs to the load is low, which can no longer meet the high requirements of users. Since air springs can bear a larger load and the adjustment accuracy of air springs to the load is higher, in order to further improve the ride comfort and handling stability of the car, air springs are widely used in suspension structures. However, the buffer response speed of existing air springs is fixed, which cannot meet the diverse usage scenario requirements of users. Summary of the invention

[0013] In a possible implementation, the flexible capsule includes:

[0014] A first flexible bladder is disposed between the first support and the second support, the first flexible bladder is used to contain a first buffer medium; and

[0015] A second flexible bladder is disposed in the first flexible bladder, and the second flexible bladder is used to contain the second buffer medium.

[0016] In a possible embodiment, the first flexible sac is connected between the first support and the second support; a first opening and a second opening are provided on the first support or the second support; the first opening is used for the first buffer medium to be input into the first flexible sac, and the second opening is used for the first buffer medium to be output from the first flexible sac.

[0018] In a possible embodiment, one end of the second flexible sac is connected to the first support, and the other end of the second flexible sac is spaced apart from the second support; a third opening and a fourth opening are provided on the first support; the third opening is used for the second buffer medium to be input into the second flexible sac, and the fourth opening is used for the second buffer medium to be output from the second flexible sac.

[0019] In a possible implementation manner, the peripheral side wall of the second flexible bladder is in a corrugated shape.

[0020] In a possible embodiment, the buffer structure further includes a guide member, which is sleeved on at least a portion of the circumference of the flexible bladder, and the guide member extends along the first support toward the second support, and the guide member is used to guide the flexible bladder.

[0021] In a possible implementation manner, the guide member has a first recess, and the first recess is arranged on a side of the guide member away from the flexible bladder.

[0026] In another aspect, the present application provides a suspension, comprising:

[0027] The above buffer structure.

[0028] In yet another aspect, a vehicle comprises:

[0029] The suspension described above.

[0030] The buffer structure, suspension and vehicle provided by the present application, on the one hand, are provided between the first support and the second support by a flexible capsule, so as to provide buffering for the first support and the second support. Moreover, the flexible capsule is used to input and / or output the first buffer medium and the second buffer medium to adjust the relative proportion of the first buffer medium and the second buffer medium in the flexible capsule. And, the density of the first buffer medium is less than the density of the second buffer medium, that is, the compressibility of the first buffer medium is greater than the compressibility of the second buffer medium. Thus, when the first buffer medium with a smaller density accounts for a larger proportion in the flexible capsule, the buffering response speed of the buffer structure is faster and the buffering shock absorption effect is better. When the second buffer medium with a larger density accounts for a larger proportion in the flexible capsule, the buffering response speed of the buffer structure is slower, but the stability of the buffer structure is better. The user can adjust the buffering strength of the flexible capsule to the first support and the second support according to the relative volume proportion of the first buffer medium and the second buffer medium in the flexible capsule according to the buffering needs. For example, when the buffer structure is applied to an environment with strong vibration, that is, the buffer structure needs a faster buffering response speed and a better buffering effect, more first buffer medium can be input into the flexible capsule. When the buffer structure is applied to an environment with less vibration, more second buffer medium can be input into the flexible capsule. Therefore, the buffer structure provided by the present application can adjust the buffer response speed and buffer shock absorption effect, which is beneficial to improve the applicability of the buffer structure in scenarios with different buffering requirements. On the other hand, since the buffer structure includes a flexible capsule, when the buffer structure is installed on the equipment, the flexible capsule of the buffer structure can form an avoidance effect on the components around the buffer structure, which can make the buffer structure installed on the equipment occupy the space of the equipment, which is beneficial to improve the overall space utilization and component integration of the equipment formed by the buffer structure.

[0040] The technical solution 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 implementation methods are only part of the implementation methods of the present application, rather than all the implementation methods. Based on the implementation methods in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0041] The following descriptions of the embodiments are with reference to the attached diagrams to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in the description of the present application, such as "upper", "lower", "front", "back", "left", "right", "inner", "outer", "top", "side", "bottom", "top wall", "side wall", "bottom wall", "inner side wall", "outer side wall", "length direction", "width direction", "height direction", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, for example, "first", "second", "third", "fourth", etc., are only used to distinguish the objects described and do not have any order or technical meaning. In the description of the present application, the "connection" and "connection" involved, if not otherwise specified, include direct connection (connection) and indirect connection (connection).

[0042] The present application provides a vehicle, which includes a suspension, a body and wheels. The suspension structure is connected between the body and the wheels. The suspension is used to provide a buffering effect on the body and the wheels to improve the smoothness and handling stability of the vehicle during driving.

[0043] The present application also provides a suspension, which includes a buffer structure, and the buffer structure is used to provide a buffering effect on one end of the suspension connected to the vehicle body and one end of the suspension connected to the wheel, so that the suspension has a buffering and shock-absorbing function.

[0044] With the development of industrial level, vehicle manufacturing technology is constantly improving, and users' requirements for vehicles are also constantly improving, which is mainly reflected in the continuous improvement of users' requirements for vehicle ride comfort and handling stability. Therefore, designers can balance the ride comfort and handling stability of vehicles to a certain extent by setting a suspension structure on the vehicle and calculating the stiffness of the spring and the damping coefficient of the shock absorber of the suspension structure through reasonable matching. However, the load that ordinary springs can bear is limited, and the adjustment accuracy of ordinary springs to the load is low, which can no longer meet the high requirements of users. Since the load that air springs can bear is larger and the adjustment accuracy of air springs to the load is higher, in order to further improve the ride comfort and handling stability of automobiles, air springs are widely used in suspension structures. However, the air springs provided by the prior art are mostly formed by a single airbag. When they are applied to suspension structures, due to the single nature of the air in the airbag, the buffering response speed of the air spring is fixed, which in turn leads to a single damping effect of the air spring, which is not convenient for use in environments with different buffering needs and damping effects.

[0045] In order to solve the technical problems existing in the above-mentioned prior art, the present application provides a buffer structure, and the buffer structure provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0046] See also Figure 1 and Figure 2 , Figure 1 This is an application scenario diagram of a buffer structure provided by an embodiment of the present application at a first perspective. Figure 2 This is a diagram of an application scenario of a buffer structure provided by an embodiment of the present application at a second perspective.

[0047] This embodiment takes the application of the buffer structure to a vehicle as an example. Figure 1 and Figure 2 The basic components of a five-link rear suspension for a vehicle with rear drive are shown. Figure 1 and Figure 2 The assembly structure of the buffer structure 100, the guide arm 101, the shock absorber 102, the subframe 103, the transmission shaft 104, the trailing arm 105, the steering knuckle 106, the upper arm 107 and the toe control arm 108 is shown. It can be seen that the buffer structure 100, as a main component for buffering and shock absorption of the vehicle, directly affects the handling stability and ride comfort of the vehicle.

[0048] See also Figure 3 , Figure 3It is a cross-sectional view of a buffer structure provided in the first embodiment of the present application.

[0049] In the first embodiment of the present application, the buffer structure 100 includes a first support 10, a second support 30 and a flexible capsule 50. The flexible capsule 50 is disposed between the first support 10 and the second support 30, and is used to provide buffering for the first support 10 and the second support 30. The flexible capsule 50 is used to accommodate the first buffer medium H1 and the second buffer medium H2, and the rigidity of the flexible capsule 50 is adjusted by adjusting the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50. The density of the first buffer medium H1 is less than that of the second buffer medium H2, that is, the compressibility of the first buffer medium H1 is greater than that of the second buffer medium H2.

[0050] The buffer structure 100 provided in the first embodiment of the present application, on the one hand, is provided between the first support 10 and the second support 30 by the flexible capsule 50, so as to provide buffering for the first support 10 and the second support 30. Moreover, the flexible capsule 50 is used to accommodate the first buffer medium H1 and the second buffer medium H2, and the stiffness of the flexible capsule 50 can be adjusted by adjusting the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50. In addition, the density of the first buffer medium H1 is less than the density of the second buffer medium H2, that is, the compressibility of the first buffer medium H1 is greater than the compressibility of the second buffer medium H2. Therefore, when the first buffer medium H1 with a smaller density accounts for a larger proportion in the flexible capsule 50, the buffer response speed of the buffer structure 100 is faster, the stiffness is smaller, and the buffering shock absorption effect is better. When the second buffer medium H2 with a larger density accounts for a larger proportion in the flexible capsule 50, the buffer response speed of the buffer structure 100 is slower, the stiffness is larger, and the stability of the buffer structure 100 is better. The user can adjust the buffering strength of the flexible capsule 50 on the first support 10 and the second support 30 by adjusting the relative volume ratio of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 according to the buffering needs. For example, when the buffer structure 100 is applied to an environment with strong vibration, that is, the buffer structure 100 requires a faster buffering response speed and a better buffering effect, more first buffering medium H1 can be input into the flexible capsule 50. When the buffer structure 100 is applied to an environment with less vibration, more second buffering medium H2 can be input into the flexible capsule 50. Therefore, the buffer structure 100 provided in the first embodiment of the present application, on the one hand, the buffering response speed and the buffering shock absorption effect can be adjusted, which is conducive to improving the applicability of the buffer structure 100 in scenarios with different buffering needs. On the other hand, since the buffer structure 100 includes a flexible bladder 50, when the buffer structure 100 is installed on the equipment, the flexible bladder 50 of the buffer structure 100 can form an avoidance effect on the components around the buffer structure 100, so that the buffer structure 100 is installed on the equipment and occupies the space of the equipment, which is beneficial to improving the overall space utilization and component integration of the equipment formed by the buffer structure 100.

[0051] For example, since the buffering response speed and the buffering shock absorbing effect of the buffering structure 100 can be adjusted, the buffering structure 100 is applied to a vehicle as an example. When the vehicle is driving, the user has high requirements for the handling stability and smoothness of the vehicle. By changing the relative proportion of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50, that is, changing the relative proportion of the volume of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50, so that the volume proportion of the first buffering medium H1 with a smaller density in the flexible capsule 50 is greater than the volume proportion of the second buffering medium H2 in the flexible capsule 50, the buffering response speed of the buffering structure 100 is faster and the buffering shock absorbing effect is better, which is conducive to improving the handling stability and smoothness of the vehicle during driving. At the same time, the specific value of the relative proportion of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50 can be further adjusted according to the road conditions and vehicle conditions of the vehicle, so that the vehicle can match different buffering response times and buffering shock absorbing effects under different road conditions and vehicle conditions. When the vehicle is stopped, the user has high requirements for the parking stability of the vehicle. The relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be changed, that is, the relative ratio of the volumes of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be changed, so that the volume proportion of the first buffer medium H1 with a smaller density in the flexible capsule 50 is smaller than the volume proportion of the second buffer medium H2 in the flexible capsule 50. The buffering response speed of the buffer structure 100 becomes slower, and the stability of the buffer structure 100 is better. The problems of spring leakage and spring collapse caused by long-term parking of the vehicle can be reduced, which is beneficial to improving the vehicle stability and durability during parking.

[0052] See also Figure 4 , Figure 4 It is a cross-sectional view of a buffer structure provided by the first embodiment of the present application in a first buffer mode.

[0053] In one embodiment, the buffer structure 100 includes a first buffer mode. In the first buffer mode, the volume occupied by the first buffer medium H1 in the flexible capsule 50 is smaller than the volume occupied by the second buffer medium H2 in the flexible capsule 50. In the first buffer mode, in the buffer structure 100 provided by the first embodiment, since the volume occupied by the first buffer medium H1 in the flexible capsule 50 is smaller than the volume occupied by the second buffer medium H2 in the flexible capsule 50, that is, the volume occupied by the first buffer medium H1 in the flexible capsule 50: the volume occupied by the second buffer medium H2 in the flexible capsule 50 is less than 1. Moreover, the density of the first buffer medium H1 is smaller than the density of the second buffer medium H2, that is, the compressibility of the first buffer medium H1 is greater than the compressibility of the second buffer medium H2, thereby making the overall compressibility of the flexible capsule 50 smaller and the rigidity of the flexible capsule 50 larger, that is, the buffer response speed of the buffer structure 100 is slower and the stability of the buffer structure 100 is better. Therefore, the buffer structure 100 provided in the first embodiment can be used in the first buffer mode when the vehicle is in a stopped state or when the environmental vibration is small, so as to improve the stability and durability of the vehicle after stopping.

[0054] See also Figure 5 , Figure 5 It is a cross-sectional view of a buffer structure provided in the first embodiment of the present application in the second buffer mode.

[0055] In one embodiment, the buffer structure 100 includes a second buffer mode. In the second buffer mode, the volume occupied by the first buffer medium H1 in the flexible capsule 50 is greater than the volume occupied by the second buffer medium H2 in the flexible capsule 50. In the second buffer mode, in the buffer structure 100 provided by the second embodiment, since the volume occupied by the first buffer medium H1 in the flexible capsule 50 is greater than the volume occupied by the second buffer medium H2 in the flexible capsule 50, that is, the volume occupied by the first buffer medium H1 in the flexible capsule 50: the volume occupied by the second buffer medium H2 in the flexible capsule 50>1. Moreover, the density of the first buffer medium H1 is less than the density of the second buffer medium H2, that is, the compressibility of the first buffer medium H1 is greater than the compressibility of the second buffer medium H2, thereby making the overall compressibility of the flexible capsule 50 larger and the rigidity of the flexible capsule 50 smaller, that is, the buffer response speed of the buffer structure 100 is fast, and the buffer shock absorption effect of the buffer structure 100 is better. Therefore, in the second buffer mode, the buffer structure 100 provided in the first embodiment can be used when the vehicle is in a driving state or when the environmental vibration is large, so as to improve the handling stability and smoothness of the vehicle during driving.

[0056] See also Figure 4 and Figure 5The buffer structure 100 provided in the first embodiment can be switched between a first buffer mode and a second buffer mode, so that the buffer structure 100 can be applicable in scenarios with different buffering requirements.

[0057] It should be understood that in some other embodiments, when the buffer structure 100 is in the first state, the volume occupied by the first buffer medium H1 in the flexible capsule 50: the volume occupied by the second buffer medium H2 in the flexible capsule 50 is less than 0.5. When the buffer structure 100 is in the second state, the volume occupied by the first buffer medium H1 in the flexible capsule 50: the volume occupied by the second buffer medium H2 in the flexible capsule 50 is greater than 0.5. This application does not limit this.

[0058] Furthermore, the first buffering mode of the buffering structure 100 may include multiple first sub-buffering modes, and in different first sub-buffering modes, the relative proportions of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50 are different, so that the buffering structure 100 can match multiple different application scenarios in the first buffering mode. The second buffering mode of the buffering structure 100 may include multiple second sub-buffering modes, and in different second sub-buffering modes, the relative proportions of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50 are different, so that the buffering structure 100 can match multiple different application scenarios in the second buffering mode.

[0059] See also Figure 4 and Figure 5 In a specific embodiment, the first buffer medium H1 is a gas buffer medium, and the second buffer medium H2 is a liquid buffer medium, and the density of the gas buffer medium is less than that of the liquid buffer medium. Since the density of the gas buffer medium is relatively small, the compressibility of the gas buffer medium is relatively large. Since the density of the liquid buffer medium is relatively large, the compressibility of the liquid is relatively small. By changing the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50, that is, changing the relative proportion of the volume of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50, the overall compressibility of the flexible capsule 50 can be adjusted, and the rigidity of the flexible capsule 50 can be adjusted, so that the buffering response speed and the buffering shock absorption effect of the buffer structure 100 can be adjusted by changing the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50, which is conducive to improving the applicability of the buffer structure 100 in different scenarios requiring buffering response and buffering shock absorption.

[0060] For example, the buffer structure 100 is applied to a vehicle. When the vehicle is in motion, the user has high requirements for the vehicle's handling stability and smoothness. By changing the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50, that is, changing the relative proportion of the volume of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50, so that the volume proportion of the gaseous first buffer medium H1 in the flexible capsule 50 is greater than the volume proportion of the liquid second buffer medium H2 in the flexible capsule 50, the buffering response speed of the buffer structure 100 is faster, the rigidity of the flexible capsule 50 is smaller, and the buffering shock absorption effect is better, which is conducive to improving the handling stability and smoothness of the vehicle in the driving process. At the same time, the specific value of the relative proportion of the gaseous first buffer medium H1 and the liquid second buffer medium H2 in the flexible capsule 50 can be further adjusted according to the road conditions and vehicle conditions of the vehicle, so that the vehicle can match different buffering response times and buffering shock absorption effects under different road conditions and vehicle conditions. When the vehicle is stopped, the user has high requirements for the parking stability of the vehicle. The relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be changed, that is, the relative ratio of the volumes of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be changed, so that the volume proportion of the gaseous first buffer medium H1 in the flexible capsule 50 is smaller than the volume proportion of the liquid second buffer medium H2 in the flexible capsule 50. The buffering response speed of the buffer structure 100 becomes slower, the rigidity of the flexible capsule 50 is larger, and the stability of the buffer structure 100 is better. The problems of spring leakage and spring collapse caused by long-term parking of the vehicle can be reduced, which is beneficial to improving the vehicle stability and durability during parking.

[0061] It should be understood that in some other embodiments, the first buffer medium H1 and the second buffer medium H2 can both be gas buffer media, or the first buffer medium H1 and the second buffer medium H2 can both be liquid buffer media. It only needs to ensure that the densities of the first buffer medium H1 and the second buffer medium H2 are different. This application does not impose any restrictions on this.

[0062] See also Figure 3In a specific embodiment, the second support 30 of the buffer structure 100 is formed with a diffusion cavity 31, which is in the shape of an annular cavity and extends along the relative direction of the first support 10 and the second support 30, and at least part of the flexible capsule 50 is accommodated in the diffusion cavity 31. By arranging the diffusion cavity 31 on the second support 30, the expandable space of the flexible capsule 50 is larger, and more first buffer medium H1 and second buffer medium H2 can be input into the flexible capsule 50, which is conducive to improving the buffering effect of the flexible capsule 50 on the first support 10 and the second support 30. Moreover, the diffusion cavity 31 is extended along the relative direction of the first support 10 and the second support 30, so that the flexible capsule cavity moves along the relative setting direction of the first support 10 and the second support 30 after being compressed, which can reduce the impact of the buffer structure 100 on the surrounding parts.

[0063] See also Figure 3 In a specific embodiment, the first support 10 of the buffer structure 100 is set at the bottom position, and the second support 30 of the buffer structure 100 is set at the top position. The second support 30 is provided with a first opening K1 and a second opening K2, and the first opening K1 and the second opening K2 are arranged at intervals. The first opening K1 is connected to the flexible capsule 50, and the first opening K1 is used for inputting the first buffer medium H1 into the flexible capsule 50. The second opening K2 is connected to the flexible capsule 50, and the second opening K2 is used for outputting the first buffer medium H1 from the flexible capsule 50. The first opening K1 and the second opening K2 are arranged on the second support 30, and the second support 30 is arranged at the top position of the buffer structure 100. Since the density of the first buffer medium H1 is less than the density of the second buffer medium H2, in the flexible capsule 50, the first buffer medium H1 is located at the position of the flexible capsule 50 close to the second support 30, and the second buffer medium H2 is located at the position of the flexible capsule 50 close to the first support 10, so that the first buffer medium H1 can be input into the flexible capsule 50 through the first opening K1, and the first buffer medium H1 can be output from the flexible capsule 50 through the second opening K2.

[0064] See also Figure 3In a specific embodiment, the first support 10 of the buffer structure 100 is set at the bottom position, and the second support 30 of the buffer structure 100 is set at the top position. The first support 10 is provided with a third opening K3 and a fourth opening K4, and the third opening K3 and the fourth opening K4 are arranged at intervals. The third opening K3 is connected to the flexible capsule 50, and the third opening K3 is used for the second buffer medium H2 to be input into the flexible capsule 50. The fourth opening K4 is connected to the flexible capsule 50, and the fourth opening K4 is used for the second buffer medium H2 to be output from the flexible capsule 50. The first opening K1 and the second opening K2 are arranged on the second support 30, and the second support 30 is arranged at the top position of the buffer structure 100. Since the density of the first buffer medium H1 is less than the density of the second buffer medium H2, in the flexible capsule 50, the first buffer medium H1 is located at the position of the flexible capsule 50 close to the second support 30, and the second buffer medium H2 is located at the position of the flexible capsule 50 close to the first support 10, so that the second buffer medium H2 can be input into the flexible capsule 50 through the third opening K3, and the second buffer medium H2 can be output from the flexible capsule 50 through the fourth opening K4. At the same time, the first opening K1 and the second opening K2 are arranged on the second support 30, and the third opening K3 and the fourth opening K4 are arranged on the first support 10, so that the input and output channels of the first buffer medium H1 and the input and output channels of the second buffer medium H2 do not affect each other, which is beneficial to improve the control of the relative ratio of the volume occupied by the first buffer medium H1 in the flexible capsule 50 to the volume occupied by the second buffer medium H2 in the flexible capsule 50, thereby making the adjustment accuracy of the buffer response and buffer shock absorption effect of the buffer structure 100 higher.

[0065] See also Figure 3 In a specific embodiment, the buffer structure 100 further includes a guide member 70, which is sleeved on the peripheral side of the flexible capsule 50, and the guide member 70 is arranged on the peripheral side of the first support 10 and the second support 30, and the guide member 70 is extended along the direction from the first support 10 to the second support 30, and the guide member 70 is used to contact with the flexible capsule 50 and guide the flexible capsule 50. Through the setting of the guide member 70, the guide member 70 is extended along the direction from the first support 10 to the second support 30 and is used to contact with the flexible capsule 50, so as to form a guiding effect on the flexible capsule 50 during the compression process, so that the flexible capsule 50 is compressed or expanded in the relative setting direction of the first support 10 and the second support 30, which is conducive to preventing the flexible capsule 50 from causing interference such as squeezing on the parts around the buffer structure 100 during the expansion or compression process, thereby making the structure formed by the buffer structure 100 more stable.

[0066] See also Figure 3More specifically, the guide member 70 has a first recess 71, which is disposed on the side of the guide member 70 away from the flexible capsule 50. By providing the first recess 71 on the guide member 70, when the buffer structure 100 is installed on the device, the flexible capsule 50 of the buffer structure 100 can form an avoidance effect on the components (such as a rotating shaft or a swing arm and other structures) around the buffer structure 100, so that the buffer structure 100 can be installed on the device and occupy the space of the device, which is conducive to improving the overall space utilization and component integration of the device formed by the buffer structure 100.

[0067] It should be understood that the number and position of the first recesses 71 can be designed according to the installation equipment and installation position of the buffer structure 100, and the present application does not impose any limitation on this.

[0068] See also Figure 3 More specifically, the guide member 70 is annular, and the flexible capsule 50 is accommodated in the annular guide member 70. The guide member 70 is set to be annular, so that the guide member 70 forms a dustproof effect on the buffer structure 100, which is conducive to preventing impurities from contacting the flexible capsule 50 and causing the flexible capsule 50 to leak, thereby improving the buffering effect of the buffer structure 100 during the working process. At the same time, the annular guide member 70 has a better guiding effect on the expansion or compression of the flexible capsule 50, which can further prevent the flexible capsule 50 from causing interference such as squeezing on the parts around the buffer structure 100 during the expansion or compression process, thereby making the structure formed by the buffer structure 100 more stable.

[0069] See also Figure 3 In a specific implementation, the buffer structure 100 also includes a dust cover 90, which is sleeved outside the flexible bladder 50, and the dust cover 90 is located between the first support 10 and the guide member 70 and between the second support 30 and the guide member 70.

[0070] Specifically, the dust cover 90 includes a first dust cover 91, which is sleeved on the peripheral side of the second support 30 and the peripheral side of the guide member 70 away from the first support 10. By setting the first dust cover 91, the first dust cover 91 cooperates with the guide member 70 to limit the expansion and compression direction of the flexible capsule 50, which can further prevent the flexible capsule 50 from causing interference such as squeezing on the parts around the buffer structure 100 during the expansion or compression process, thereby making the structure formed by the buffer structure 100 more stable. At the same time, the first dust cover 91 forms a dustproof effect on the buffer structure 100, which is conducive to preventing impurities from contacting the flexible capsule 50 and causing the flexible capsule 50 to leak, thereby improving the buffering effect of the buffer structure 100 during the working process.

[0071] Furthermore, the first dust cover 91 has a second depression 911, and the second depression 911 is arranged on the side of the first dust cover 91 away from the flexible capsule 50. By arranging the second depression 911 on the first dust cover 91, when the buffer structure 100 is installed on the device, the flexible capsule 50 of the buffer structure 100 can form an avoidance effect on the parts (for example, structures such as a rotating shaft or a swing arm) around the buffer structure 100, so that the buffer structure 100 can be installed on the device to occupy the space of the device, which is conducive to improving the overall space utilization and component integration of the device formed by the buffer structure 100.

[0072] Specifically, the dust cover 90 also includes a second dust cover 92, which is sleeved on the peripheral side of the first support 10 and the peripheral side of the guide member 70 away from the second support 30. By setting the second dust cover 92, the second dust cover 92 cooperates with the guide member 70 to limit the expansion and compression direction of the flexible capsule 50, which can further prevent the flexible capsule 50 from causing interference such as squeezing on the parts around the buffer structure 100 during the expansion or compression process, thereby making the structure formed by the buffer structure 100 more stable. At the same time, the second dust cover 92 forms a dustproof effect on the buffer structure 100, which is conducive to preventing impurities from contacting the flexible capsule 50 and causing the flexible capsule 50 to leak, thereby improving the buffering effect of the buffer structure 100 during the working process.

[0073] See also Figure 6 and Figure 7 , Figure 6 is a cross-sectional view of a buffer structure provided by the second embodiment of the present application in a first buffer mode, Figure 7 It is a cross-sectional view of a buffer structure provided by the second embodiment of the present application in a second buffer mode.

[0074] The buffer structure 100 provided in the second embodiment of the present application is substantially the same as the buffer structure 100 provided in the first embodiment of the present application, and the main difference lies in that the flexible bladder 50 provided in the second embodiment of the present application includes a first flexible bladder 51 and a second flexible bladder 52 , and the second flexible bladder 52 is accommodated in the first flexible bladder 51 .

[0075] Specifically, in the buffer structure 100 provided in the second embodiment of the present application, the flexible capsule 50 includes a first flexible capsule 51 and a second flexible capsule 52. The first flexible capsule 51 is arranged between the first support 10 and the second support 30. The first flexible capsule 51 is used to input and / or output the first buffer medium H1 and provide buffering for the first support 10 and the second support 30. The second flexible capsule 52 is arranged in the first flexible capsule 51. The second flexible capsule 52 is used to input and / or output the second buffer medium H2 and buffer the first buffer medium H1 in the first flexible capsule 51, and is also used to control the proportion of the first buffer medium H1 in the first flexible capsule 51. The relative proportions of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be adjusted. The density of the first buffer medium H1 is less than that of the second buffer medium H2, that is, the compressibility of the first buffer medium H1 is greater than the compressibility of the second buffer medium H2.

[0076] More specifically, the buffer structure 100 provided in the second embodiment of the present application also includes a first buffer mode and a second buffer mode, and the buffer structure 100 can switch between the first buffer mode and the second buffer mode. The buffer structure 100 switches between the first buffer mode and the second buffer mode by controlling the relative proportion of the first buffer medium H1 in the first flexible capsule 51 and the second buffer structure 100 in the second flexible capsule 52.

[0077] The buffer structure 100 provided in the second embodiment of the present application is provided between the first support 10 and the second support 30 through the flexible capsule 50, the first flexible capsule 51 is used to provide buffering for the first support 10 and the second support 30, the second flexible capsule 52 is used to provide buffering for the first flexible capsule 51, and the second flexible capsule 52 is also used to control the proportion of the first buffer medium H1 in the first flexible capsule 51. Therefore, by controlling the input or output of the second buffer medium H2 in the second flexible capsule 52, the volume proportion of the first buffer medium H1 and the second buffer medium H2 in the buffer structure 100 can be controlled, and the density of the first buffer medium H1 is less than the density of the second buffer medium H2, that is, the compressibility of the first buffer medium H1 is greater than the compressibility of the second buffer medium H2. Therefore, when the first buffer medium H1 with a smaller density accounts for a larger proportion in the flexible capsule 50, that is, when the buffer structure 100 is in the second buffer state, the buffer response speed of the buffer structure 100 is faster, the overall stiffness of the flexible capsule 50 is smaller, and the buffer shock absorption effect is better. When the second buffer medium H2 with a higher density accounts for a larger proportion in the flexible capsule 50, that is, when the buffer structure 100 is in the first buffer state, the buffer response speed of the buffer structure 100 is slower, the overall rigidity of the flexible capsule 50 is larger, and the stability of the buffer structure 100 is better. The user can adjust the buffering strength of the flexible capsule 50 on the first support 10 and the second support 30 by the relative volume proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 according to the buffering needs. For example, when the buffer structure 100 is applied to an environment with strong vibration, that is, the buffer structure 100 requires a faster buffer response speed and a better buffering effect, more first buffer medium H1 can be input into the flexible capsule 50 to put the buffer structure 100 in the second buffer state. When the buffer structure 100 is applied to an environment with less vibration, more second buffer medium H2 can be input into the flexible capsule 50 to put the buffer structure 100 in the first buffer state. Therefore, the buffer structure 100 provided in the second embodiment of the present application, on the one hand, the buffer response speed and the buffer shock absorption effect can be adjusted, that is, the overall stiffness of the flexible capsule 50 can be adjusted, which is conducive to improving the applicability of the buffer structure 100 in different scenarios where buffering is required. On the other hand, since the buffer structure 100 includes the flexible capsule 50, when the buffer structure 100 is installed on the equipment, the flexible capsule 50 of the buffer structure 100 can form an avoidance effect on the components around the buffer structure 100, which can make the buffer structure 100 installed on the equipment occupy the space of the equipment, which is conducive to improving the overall space utilization and component integration of the equipment formed by the buffer structure 100.

[0078] For example, since the buffering response speed and the buffering shock absorbing effect of the buffering structure 100 can be adjusted, so that the buffering structure 100 can switch between the first buffering state and the second buffering state, take the buffering structure 100 applied to a vehicle as an example. When the vehicle is driving, the user has high requirements for the handling stability and smoothness of the vehicle. By changing the relative proportion of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50, that is, changing the relative proportion of the volume of the first buffering medium H1 and the second buffering medium H2 in the flexible capsule 50, so that the volume proportion of the first buffering medium H1 with a smaller density in the flexible capsule 50 is greater than the volume proportion of the second buffering medium H2 in the flexible capsule 50, and then the buffering structure 100 is in the second buffering state, the buffering response speed of the buffering structure 100 is faster, the overall stiffness of the flexible capsule 50 is smaller, and the buffering shock absorbing effect is better, which is conducive to improving the handling stability and smoothness of the vehicle during driving. At the same time, the specific value of the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be further adjusted according to the road conditions and vehicle conditions of the vehicle, so that the vehicle can match different buffer response times and buffer shock absorption effects under different road conditions and vehicle conditions. When the vehicle is stopped, the user has high requirements for the parking stability of the vehicle. The relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be changed, that is, the relative proportion of the volume of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50 can be changed, so that the volume proportion of the first buffer medium H1 with a smaller density in the flexible capsule 50 is smaller than the volume proportion of the second buffer medium H2 in the flexible capsule 50, thereby making the buffer structure 100 in the first buffer state, the buffer response speed of the buffer structure 100 slows down, the overall stiffness of the flexible capsule 50 is larger, and the stability of the buffer structure 100 is better, which can reduce the problems of spring leakage and spring collapse caused by long-term parking of the vehicle, and is conducive to improving the vehicle stability and durability during parking.

[0079] See also Figure 6 and Figure 7In a specific embodiment, the first buffer medium H1 is a gas buffer medium, and the second buffer medium H2 is a liquid buffer medium, and the density of the gas buffer medium is less than that of the liquid buffer medium. Since the density of the gas buffer medium is relatively small, the compressibility of the gas buffer medium is relatively large. Since the density of the liquid buffer medium is relatively large, the compressibility of the liquid is relatively small. By changing the relative proportion of the first buffer medium H1 and the second buffer medium H2 in the flexible capsule 50, that is, changing the relative proportion of the volume of the first buffer medium H1 in the first flexible capsule 51 and the volume of the second buffer medium H2 in the second flexible capsule 52, the overall compressibility of the flexible capsule 50 can be adjusted, and then the buffer response speed and buffer shock absorption effect of the buffer structure 100 can be adjusted by changing the relative proportion of the first buffer medium H1 in the first flexible capsule 51 and the second buffer medium H2 in the second flexible capsule 52 in the flexible capsule 50, which is conducive to improving the applicability of the buffer structure 100 in different scenarios requiring buffer response and buffer shock absorption.

[0080] For example, the application of the buffer structure 100 to a vehicle is taken as an example. When the vehicle is in motion, the user has high requirements for the handling stability and smoothness of the vehicle. By changing the relative proportion of the first buffer medium H1 in the first flexible capsule 51 and the second buffer medium H2 in the second flexible capsule 52 in the flexible capsule 50, that is, changing the relative proportion of the volume of the first buffer medium H1 in the first flexible capsule 51 and the second buffer medium H2 in the second flexible capsule 52 in the flexible capsule 50, so that the volume proportion of the first buffer medium H1 in the gaseous first flexible capsule 51 in the flexible capsule 50 is greater than the volume proportion of the second buffer medium H2 in the liquid second flexible capsule 52 in the flexible capsule 50, the buffer structure 100 has a faster buffer response speed, the overall stiffness of the flexible capsule 50 is smaller, and the buffer shock absorption effect is better, which is conducive to improving the handling stability and smoothness of the vehicle during driving. At the same time, the specific values ​​of the relative proportions of the first buffer medium H1 in the gaseous first flexible capsule 51 and the second buffer medium H2 in the liquid second flexible capsule 52 in the flexible capsule 50 can be further adjusted according to the road conditions and vehicle conditions of the vehicle, so that the vehicle can match different buffer response times and buffer shock absorption effects under different road conditions and vehicle conditions. When the vehicle is stopped, the user has high requirements for the parking stability of the vehicle. The relative proportion of the first buffer medium H1 in the first flexible capsule 51 and the second buffer medium H2 in the second flexible capsule 52 in the flexible capsule 50 can be changed, that is, the relative proportion of the volume of the first buffer medium H1 in the first flexible capsule 51 and the second buffer medium H2 in the second flexible capsule 52 in the flexible capsule 50 is changed, so that the volume proportion of the gaseous first buffer medium H1 in the first flexible capsule 51 in the flexible capsule 50 is smaller than the volume proportion of the liquid second buffer medium H2 in the second flexible capsule 52 in the flexible capsule 50. The buffering response speed of the buffer structure 100 is slowed down, the overall stiffness of the flexible capsule 50 is larger, and the stability of the buffer structure 100 is better. The problems of spring leakage and spring collapse caused by long-term parking of the vehicle can be reduced, which is beneficial to improving the vehicle stability and durability during parking.

[0081] It should be understood that in some other embodiments, the first buffer medium H1 and the second buffer medium H2 can both be gas buffer media, the first buffer medium H1 and the second buffer medium H2 can both be liquid buffer media, the first buffer medium H1 can be a liquid buffer medium and the second buffer medium H2 can be a gaseous buffer medium. It only needs to ensure that the densities of the first buffer medium H1 and the second buffer medium H2 are different, and the present application does not impose any restrictions on this.
