Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle accessories, in particular to a bottom bowl assembly. The present application also relates to a hydraulic suspension provided with the bottom bowl assembly, and a vehicle provided with the hydraulic suspension. BACKGROUND

[0002] A kind of air spring type semi-active control hydraulic suspension (CN104154171A) is proposed in the related art, which needs to realize the sealing effect between bottom bowl and shell by interference fit or excessive compression force. However, due to the machining error, assembly error and other conditions of parts, the bottom bowl and the shell cannot achieve good sealing effect, resulting in leakage of damping fluid in the hydraulic chamber of the hydraulic suspension, affecting the normal work of the hydraulic suspension. CONTENT OF UTILITY MODEL

[0003] Therefore, the present application aims to provide a bottom bowl assembly, a hydraulic suspension and a vehicle, which can solve the problem of poor sealing effect between the bottom bowl and the shell.

[0004] To achieve the above purpose, the technical scheme of the present application is as follows:

[0005] A kind of bottom bowl assembly, comprising: bottom bowl body;

[0006] The outer wall of the bottom bowl body is provided with a first ring groove;

[0007] The first ring groove comprises a first ring wall and a second ring wall spaced apart along the axial direction of the bottom bowl body, at least part of the second ring wall extends obliquely towards the first ring wall, and at least part of the second ring wall is deformable towards the direction away from the first ring wall.

[0008] In the present application, the outer wall of the bottom bowl body is provided with a first ring groove, so that the damping fluid can enter the first ring groove, and at least part of the second ring wall of the first ring groove is inclined towards the first ring wall and can be deformed. Thus, when the damping fluid enters the first ring groove, the pressure in the first ring groove can be increased, and the second ring wall can be deformed towards the direction away from the first ring wall under the extrusion of the damping fluid, so as to realize sealing by abutting the second ring wall and other components (such as shell, etc.). Based on the above arrangement, the structure of the bottom bowl body is redesigned in the present application, which can improve the sealing effect after the bottom bowl body and other components (such as shell, etc.) are assembled. Compared with the way of realizing sealing effect by interference fit or excessive compression force between bottom bowl and shell in the related art, the present application can effectively avoid the leakage of damping fluid caused by poor sealing between bottom bowl and shell due to machining error and assembly error of parts.

[0009] Another object of the present application is to provide a hydraulic mount, comprising a housing, a rubber main spring, a flow channel assembly, and the bottom bowl assembly as described above;

[0010] The rubber main spring, the flow channel assembly, and the bottom bowl assembly are sequentially arranged in the inner cavity of the housing along the axial direction of the hydraulic mount, the flow channel assembly and the rubber main spring form a first liquid chamber, the flow channel assembly and the bottom bowl assembly form a second liquid chamber, and the first liquid chamber and the second liquid chamber are in communication through the flow channel assembly;

[0011] The outer peripheral wall of the first annular wall and the inner wall of the housing have a gap therebetween, so that the first annular groove is in communication with the second liquid chamber;

[0012] In the case where the second annular wall is deformed, the outer peripheral wall of the second annular wall abuts against the inner wall of the housing.

[0013] The hydraulic mount described in the embodiments of the present application has the same beneficial effects as the bottom bowl assembly described above, and thus will not be described here again.

[0014] The embodiments of the present application further provide a vehicle comprising the hydraulic mount described above.

[0015] The vehicle described in the embodiments of the present application has the same beneficial effects as the hydraulic mount described above, and thus will not be described here again. BRIEF DESCRIPTION OF DRAWINGS

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0037] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0038] The embodiments of the present application will be described in detail below in conjunction with the drawings and specific examples and their application scenarios.

[0039] refer to Figures 1 to 8 This application discloses a bottom cup assembly 01, which can be applied to a hydraulic suspension. The bottom cup assembly 01 can contain and seal the damping fluid in the hydraulic suspension to ensure the normal use of the hydraulic suspension.

[0040] like Figure 8 As shown, the disclosed bottom bowl assembly 01 includes a bottom bowl body 10, which can be disposed in the hydraulically suspended housing 02. On the one hand, it can contain the damping fluid in the housing 02, and on the other hand, it can form a good seal with the housing 02 to prevent leakage of the damping fluid.

[0041] The outer wall of the base bowl body 10 may be provided with a first annular groove 11, which can be used to contain damping fluid. Optionally, the opening of the first annular groove 11 may communicate with the inner cavity of the housing 02, so that the damping fluid in the inner cavity of the housing 02 can enter the first annular groove 11.

[0042] For example, the first annular groove 11 can be a circular annular groove, a polygonal annular groove, an elliptical annular groove, etc., and can be specifically set according to the shape of the hydraulic suspension, and the specific shape is not limited. In some more specific embodiments, the cross-section of the hydraulic suspension can be circular, and correspondingly, the cross-section of the housing 02 of the hydraulic suspension and the cross-section of the bottom bowl body 10 can both be circular. In this case, the first annular groove 11 located on the outer wall of the bottom bowl body 10 can be a circular annular groove.

[0043] Continue to refer to Figure 8 The first annular groove 11 may include a first annular wall 111 and a second annular wall 112, and the first annular wall 111 and the second annular wall 112 are spaced apart along the axial direction of the bottom bowl body 10. In this way, the first annular wall 111, the second annular wall 112 and the outer wall of the bottom bowl body 10 can together form the inner cavity of the first annular groove 11, and the opening of the first annular groove 11 can face away from the outer wall.

[0044] Optionally, the first ring wall 111, the second ring wall 112 and the base bowl body 10 can be integrally formed. That is, during the manufacturing process of the base bowl body 10, the first ring wall 111 and the second ring wall 112 are formed on the outer wall of the base bowl body 10. This method can shorten the manufacturing cycle and improve manufacturing efficiency.

[0045] Of course, the first ring wall 111 and the second ring wall 112 can also be fixedly connected to the outer wall of the bottom bowl body 10, such as by bonding or welding. This method can reduce the manufacturing difficulty.

[0046] In some more specific embodiments, the bottom bowl body 10, the first ring wall 111 and the second ring wall 112 can be integrally injection molded. For example, the entire bottom bowl body 10, the first ring wall 111 and the second ring wall 112 can be a rubber injection molded piece.

[0047] When the bottom bowl body 10 is actually installed into the housing 02 of the hydraulic mount, the first ring wall 111 can be located on the side close to the liquid inlet end of the housing 02, and the second ring wall 112 can be located on the side away from the liquid inlet end of the housing 02. Based on this, the damping liquid in the housing 02 can enter the first ring groove 11 from the side of the first ring wall 111 and be blocked by the second ring wall 112.

[0048] In some embodiments, at least part of the second ring wall 112 extends obliquely towards the first ring wall 111. In this way, on the one hand, when the damping liquid in the housing 02 enters the first ring groove 11, the second ring wall 112 can limit the damping liquid to a certain extent, so that when the damping liquid continues to flow into the first ring groove 11, the inner side of the second ring wall 112 can be subjected to greater pressure from the damping liquid, and on the other hand, when the pressure of the damping liquid increases, the second ring wall 112 can still be in good contact with the inner wall of the housing 02 without being deformed at will, ensuring that the second ring wall 112 has good sealing with the inner wall of the housing 02, thereby effectively preventing the damping liquid from leaking between the second ring wall 112 and the inner wall of the housing 02.

[0049] Further, at least part of the second ring wall 112 can be deformable towards the direction away from the first ring wall 111. In this way, when at least part of the second ring wall 112 is deformed, it can be used to abut against the inner wall of the housing 02 of the hydraulic mount to play a sealing role. Alternatively, under the pressure of the damping liquid in the first ring groove 11, at least part of the second ring wall 112 can be deformed towards the direction of the first ring wall 111, so that the second ring wall 112 abuts against the inner wall of the housing 02 to play a sealing role.

[0050] It should be noted here that the second ring wall 112 can extend obliquely towards the first ring wall 111 in part, or extend obliquely towards the first ring wall 111 as a whole, which can be selected according to the actual working conditions.

[0051] In the embodiment of the present application, the first annular groove 11 is arranged on the outer wall of the bottom bowl body 10, so that the damping liquid can enter the first annular groove 11, and at least part of the second annular wall 112 of the first annular groove 11 is inclined toward the first annular wall 111 and can be deformed. In this way, when the damping liquid enters the first annular groove 11, the pressure in the first annular groove 11 can be increased, and under the extrusion of the damping liquid, the second annular wall 112 can be deformed in a direction away from the first annular wall 111, so as to tightly abut the second annular wall 112 against other components (such as the shell 02) to achieve sealing.

[0052] Based on the above arrangement, the structure of the bottom bowl body 10 is redesigned in the embodiment of the present application. After the bottom bowl body 10 is assembled with other components (such as the shell 02), the sealing effect can be improved. Compared with the related art which uses interference fit or excessive pressing force of the bottom bowl and the shell to achieve the sealing effect, the embodiment of the present application can effectively avoid the leakage of the damping liquid caused by the machining error and assembly error of the bottom bowl, the shell and other components, which leads to poor sealing between the bottom bowl and the shell.

[0053] Continuing to refer to Figure 8 In some embodiments, the second annular wall 112 can include a first annular portion 1121 and a second annular portion 1122, wherein the first annular portion 1121 is arranged on the outer wall of the bottom bowl body 10, and the second annular portion 1122 is arranged on one end of the first annular portion 1121 away from the outer wall. Optionally, the first annular portion 1121 and the second annular portion 1122 can be fixedly connected, and can also be an integral structure.

[0054] Further, at least one of the first annular portion 1121 and the second annular portion 1122 can extend obliquely toward the first annular wall 111, and the second annular portion 1122 can be deformed in a direction away from the first annular wall 111. In this way, at least part of the second annular wall 112 can extend obliquely toward the first annular wall 111, so as to bear the pressure of the damping liquid in the first annular groove 11.

[0055] In some embodiments, the first annular portion 1121 and the first annular wall 111 can be arranged in parallel, and the second annular portion 1122 can extend curvedly toward the first annular wall 111. In this way, the inner side surface of the second annular portion 1122 can bear the pressure of the damping liquid in the first annular groove 11, so that the second annular portion 1122 can be deformed in a direction away from the first annular wall 111. Optionally, the entire second annular portion 1122 can be deformed, or only part of the second annular portion 1122 can be deformed.

[0056] In some embodiments, the first ring portion 1121 can extend obliquely towards the first ring wall 111, and the second ring portion 1122 can be arranged parallel to the first ring wall 111, so that the second ring wall 112 can also extend obliquely towards the first ring wall 111. In this way, the inner side surface of the second ring portion 1122 can bear the pressure of the damping liquid in the first ring groove 11, so that the second ring portion 1122 can deform towards the direction away from the first ring wall 111.

[0057] In some other embodiments, the first ring portion 1121 and the second ring portion 1122 can extend obliquely towards the first ring wall 111, respectively. In this way, the inner side surface of the second ring portion 1122 can bear the pressure of the damping liquid in the first ring groove 11, so that the second ring portion 1122 can deform towards the direction away from the first ring wall 111.

[0058] Of course, the above-mentioned three ways are not the only possible ways, and other ways are also possible, which are not limited herein.

[0059] In addition, at least one of the first ring portion 1121 and the second ring portion 1122 can deform towards the direction away from the first ring wall 111, so that the second ring wall 112 can tightly seal against the inner wall of the housing 02.

[0060] It is considered that when the pressure of the damping liquid in the first ring groove 11 is relatively large, even if the second ring wall 112 tightly seals against the inner wall of the housing 02, a certain sealing effect can be achieved, but excessive pressure can cause the damping liquid to leak from the gap between the second ring wall 112 and the inner wall of the housing 02.

[0061] Based on the above, the outer wall of the bottom bowl body 10 can further be provided with a second ring groove 12, which is arranged along the axial direction of the bottom bowl body 10 and located on the side close to the second ring wall 112. In this way, even if the damping liquid leaks from the second ring wall 112, the leaked damping liquid can be collected by the second ring groove 12 to prevent the damping liquid from leaking to the outside.

[0062] Optionally, the second ring groove 12 can be a circular ring groove, a polygonal ring groove, an elliptical ring groove, etc., which can be determined according to the shape of the hydraulic mount, and the specific shape is not limited. In some specific embodiments, the cross section of the hydraulic mount can be circular, and correspondingly, the cross section of the housing 02 and the cross section of the bottom bowl body 10 can also be circular. In this case, the second ring groove 12 on the outer wall of the bottom bowl body 10 can be a circular ring groove.

[0063] Of course, with the long time use of the hydraulic suspension, the leakage flow of the damping liquid is more and more large, so that the pressure of the damping liquid in the second annular groove 12 is more and more large, which is easy to cause the damping liquid to leak out of the second annular groove 12. Based on the above situation, the structure of the second annular groove 12 is also designed in the embodiments of the present application, so as to fully utilize the pressure of the damping liquid and improve the sealing performance, and effectively prevent the damping liquid from leaking outwards.

[0064] With reference to the foregoing Figure 8 In some embodiments, the second annular groove 12 can include a third annular wall 121 and a fourth annular wall 122, the third annular wall 121 and the fourth annular wall 122 are arranged along the axial direction of the bottom bowl body 10 and are spaced apart, and the third annular wall 121 is arranged close to the first annular groove 11, so that the leaked damping liquid in the first annular groove 11 can enter the second annular groove 12 through the third annular wall 121 to collect the leaked damping liquid through the second annular groove 12.

[0065] In addition, at least part of the fourth annular wall 122 can extend obliquely towards the third annular wall 121, so that when the damping liquid leaked from the first annular groove 11 enters the second annular groove 12, the fourth annular wall 122 can play a certain limiting role on the damping liquid, so that in the case of continuing to leak the damping liquid into the second annular groove 12, the fourth annular wall 122 can be deformed by the damping liquid on the inner side of the fourth annular wall 122. On the other hand, the fourth annular wall 122 can still be in good contact with the inner wall of the shell 02 without being deformed at will under the condition of increasing the pressure of the damping liquid, so as to ensure that the fourth annular wall 122 has good sealing performance with the inner wall of the shell 02, thereby effectively preventing the damping liquid from leaking between the fourth annular wall 122 and the inner wall of the shell 02.

[0066] Further, at least part of the fourth annular wall 122 can also be deformed towards the direction away from the third annular wall 121, so that in the case of deformation of at least part of the fourth annular wall 122, the fourth annular wall 122 can be in abutment with the inner wall of the shell 02 of the hydraulic suspension to play a sealing role. Alternatively, under the pressure of the damping liquid in the second annular groove 12, the fourth annular wall 122 can be in abutment with the inner wall of the shell 02 to play a sealing role.

[0067] It should be noted here that the fourth annular wall 122 can extend obliquely towards the third annular wall 121 in part, and can also extend obliquely towards the third annular wall 121 as a whole, which can be selected according to the actual working condition.

[0068] Based on the above arrangement, the sealing can also be formed at the fourth annular wall 122 on the basis of the sealing formed at the second annular wall 112, so as to greatly increase the sealing effect to prevent the damping liquid from leaking outwards.

[0069] In some embodiments, the third annular wall 121 and the second annular wall 112 can be the same annular wall, i.e., the first annular groove 11 and the second annular groove 12 share the second annular wall 112 (or the third annular wall 121); of course, the third annular wall 121 and the second annular wall 112 can also be independent annular walls, in which case the structure of the third annular wall 121 can be the same as that of the second annular wall 112, or the same as that of the first annular wall 111.

[0070] When the third annular wall 121 and the second annular wall 112 are the same annular wall, or when the third annular wall 121 and the second annular wall 112 are independent of each other and have the same structure, the structure of the fourth annular wall 122 can also be the same as that of the third annular wall 121.

[0071] Optionally, the number of the second annular grooves 12 can be one or more, when the pressure of the damping liquid in the housing 02 of the hydraulic suspension is small, one second annular groove 12 can be provided, and when the pressure of the damping liquid is large, multiple second annular grooves 12 can be provided, which can be selected according to the actual working conditions.

[0072] When the second annular grooves 12 are multiple, the same annular wall can be shared between adjacent two second annular grooves 12.

[0073] Continuing to refer to Figure 8 In some embodiments, the outer wall of the bottom bowl body 10 can also be provided with a third annular groove 13, which is arranged along the axial direction of the bottom bowl body 10 and located on the side close to the second annular wall 112, so that by introducing pressure gas into the third annular groove 13, the pressure in the third annular groove 13 can be increased, so that the pressure of the pressure gas can be counteracted by the liquid pressure of the damping liquid, thereby balancing the pressure in the third annular groove 13 and the first annular groove 11 to form an air seal and hinder the damping liquid about to leak in the first annular groove 11.

[0074] Of course, when the outer wall of the bottom bowl body 10 is also provided with the second annular groove 12, the first annular groove 11, the second annular groove 12 and the third annular groove 13 can be sequentially arranged along the axial direction of the bottom bowl body 10, in which case the pressure gas in the third annular groove 13 can balance the pressure in the third annular groove 13 and the second annular groove 12 to form an air seal and hinder the damping liquid about to leak in the second annular groove 12.

[0075] Optionally, the third annular groove 13 can be a circular annular groove, a polygonal annular groove, an elliptical annular groove, etc., which can be determined according to the shape of the hydraulic suspension, and the specific shape is not limited. In some more specific embodiments, the cross section of the hydraulic suspension can be circular, and correspondingly, the cross section of the housing 02 of the hydraulic suspension and the cross section of the bottom bowl body 10 can also be circular, in which case the third annular groove 13 located on the outer wall of the bottom bowl body 10 can be a circular annular groove.

[0076] The third annular groove 13 can include a fifth annular wall 131 and a sixth annular wall 132, the fifth annular wall 131 and the sixth annular wall 132 are arranged along the axial direction of the bottom bowl body 10, and the fifth annular wall 131 is close to the first annular groove 11 or the second annular groove 12; and at least part of the fifth annular wall 131 can extend obliquely towards the sixth annular wall 132. Based on this arrangement, when the pressure gas enters the third annular groove 13, the pressure gas can be limited by the fifth annular wall 131, so as to increase the pressure in the third annular groove 13, and in the case of increased gas pressure in the third annular groove 13, the sixth annular wall 132 can still be in good contact with the inner wall of the shell 02 without being deformed at will, ensuring that the sixth annular wall 132 has good sealing with the inner wall of the shell 02, thereby effectively preventing gas from leaking between the sixth annular wall 132 and the inner wall of the shell 02.

[0077] Further, at least part of the fifth annular wall 131 can also deform towards the direction of the sixth annular wall 132, so that in the case of deformation of at least part of the fifth annular wall 131, the fifth annular wall 131 can be tightly pressed against the inner wall of the shell 02 of the hydraulic suspension to further play a sealing role. Alternatively, under the action of the gas pressure in the third annular groove 13, the fifth annular wall 131 can be tightly pressed against the inner wall of the shell 02 to play a sealing role.

[0078] It should be noted here that the fifth annular wall 131 can extend obliquely towards the sixth annular wall 132 in part, or extend obliquely towards the sixth annular wall 132 as a whole, which can be selected according to actual working conditions.

[0079] Based on the above arrangement, on the basis of forming a seal at the second annular wall 112, or on the basis of forming a seal at the second annular wall 112 and forming a seal at the fourth annular wall 122, a seal can also be formed at the fifth annular wall 131, thereby greatly increasing the sealing effect to prevent the damping liquid from leaking outward; at the same time, the pressure gas can also play a counteracting role with the damping liquid leaked at the second annular wall 112 or the damping liquid leaked from the fourth annular wall 122 to form a gas seal at the second annular wall 112 or the fourth annular wall 122, effectively preventing the damping liquid from leaking.

[0080] It should be noted here that the oblique direction of the fifth annular wall 131 is opposite to the oblique direction of the second annular wall 112, or the oblique direction of the fifth annular wall 131 is opposite to the oblique direction of the fourth annular wall 122, so that a bidirectional sealing form can be realized, which is beneficial to improve the sealing effect. Alternatively, the specific structure of the fifth annular wall 131 can be the same as that of the second annular wall 112, and the oblique directions are opposite.

[0081] Continuing to refer to Figure 8In some embodiments, the outer wall of the bottom bowl body 10 can further be provided with a fourth annular groove 14, which is arranged between the first annular groove 11 and the third annular groove 13, and the fourth annular groove 14 shares the second annular wall 112 with the first annular groove 11, and the fourth annular groove 14 shares the fifth annular wall 131 with the third annular groove 13. Based on this arrangement, the pressure gas in the third annular groove 13 can leak into the fourth annular groove 14 through the fifth annular wall 131, so that the pressure in the fourth annular groove 14 increases, thereby balancing the pressure between the fourth annular groove 14 and the first annular groove 11, and the pressure gas in the fourth annular groove 14 can also counteract the damping liquid about to leak from the first annular groove 11 at the second annular wall 112, thereby forming an air seal at the second annular wall 112 to hinder the damping liquid from leaking from the second annular wall 112.

[0082] In other embodiments, the bottom bowl body 10 can be further provided with the first annular groove 11, the second annular groove 12, the fourth annular groove 14 and the third annular groove 13 arranged along the axial direction of the bottom bowl body 10 in sequence, and the fourth annular groove 14 and the second annular groove 12 can share the same annular wall (i.e., the fourth annular wall 122), and the fourth annular groove 14 and the third annular groove 13 can share the fifth annular wall 131. Based on this arrangement, the pressure gas in the third annular groove 13 can leak into the fourth annular groove 14 through the fifth annular wall 131, so that the pressure in the fourth annular groove 14 increases, and the damping liquid leaked from the first annular groove 11 is collected in the second annular groove 12, thereby increasing the pressure in the second annular groove 12, so that the pressure gas can balance the pressure between the fourth annular groove 14 and the second annular groove 12, and at the same time, the pressure gas in the fourth annular groove 14 can also counteract the damping liquid about to leak from the second annular groove 12 at the annular wall shared by the fourth annular groove 14 and the second annular groove 12 (i.e., the fourth annular wall 122), thereby forming an air seal at the shared annular wall to hinder the damping liquid from leaking from the shared annular wall of the fourth annular groove 14 and the second annular groove 12.

[0083] Of course, in other embodiments, the fourth annular groove 14 can be independent of the first annular groove 11 and the third annular groove 13, i.e., the fourth annular groove 14 does not share an annular wall with the first annular groove 11 and the third annular groove 13, or the fourth annular groove 14, the second annular groove 12 and the third annular groove 13 can be independent of each other, i.e., the fourth annular groove 14 does not share an annular wall with the second annular groove 12 and the third annular groove 13.

[0084] To support the bottom bowl body 10, the bottom bowl assembly 01 can further include a support framework 20, such as Figure 4 and Figure 8As shown, the support framework 20 is arranged in the fourth annular groove 14, so that the support framework 20 can support and limit the annular wall of the fourth annular groove 14 and the outer wall of the bottom bowl body 10 respectively, to prevent the bottom bowl body 10 from being deformed or even collapsed under pressure, thereby ensuring the sealing effect of the bottom bowl body 10.

[0085] Optionally, the support framework 20 can have a ring structure. For example, the support framework 20 can include a first branch, a second branch, and a connecting arm, wherein the first branch can extend obliquely towards the second annular wall 112 or the fourth annular wall 122 and abut against the second annular wall 112 or the fourth annular wall 122; the second branch can extend obliquely towards the fifth annular wall 131 and abut against the fifth annular wall 131; and the connecting arm is connected between the first branch and the second branch and abuts against the outer wall of the bottom bowl body 10. Based on this arrangement, the support framework 20 can support and limit the second annular wall 112 or the fourth annular wall 122, the fifth annular wall 131, and the outer wall respectively, thereby effectively preventing the bottom bowl body 10 from being deformed and reducing the sealing effect.

[0086] In some embodiments, the bottom bowl body 10 and the support framework 20 can be integrally vulcanized, or the support framework 20 can be arranged in the fourth annular groove 14 outside the bottom bowl body 10.

[0087] Based on the above-mentioned bottom bowl assembly 01, the embodiments of the present application further disclose a hydraulic suspension. Referring to Figures 1 to 8 , the disclosed hydraulic suspension includes a housing 02, a rubber main spring 03, a flow channel assembly 04, an inner core 05, a protective cover 06, and the above-mentioned bottom bowl assembly 01.

[0088] As shown in Figure 4 , the inner core 05, the rubber main spring 03, the flow channel assembly 04, the bottom bowl assembly 01, and the protective cover 06 are sequentially arranged in the inner cavity of the housing 02 along the axial direction of the hydraulic suspension, and the flow channel assembly 04 and the rubber main spring 03 can form a first liquid chamber M, the flow channel assembly 04 and the bottom bowl assembly 01 can form a second liquid chamber N, and the first liquid chamber M and the second liquid chamber N can be communicated through the flow channel assembly 04.

[0089] Based on this arrangement, during the filling of the damping liquid, the damping liquid can enter the first liquid chamber M through the inner core 05 and the rubber main spring 03, and enter the second liquid chamber N through the flow channel assembly 04. In addition, during the normal operation of the hydraulic suspension, the damping liquid can flow between the first liquid chamber M and the second liquid chamber N, and is subjected to damping during the flow, thereby achieving a certain buffering and damping effect, meeting the actual demand.

[0090] Optionally, the inner core 05, the rubber main spring 03, the flow channel assembly 04, the bottom bowl assembly 01 and the protective cover 06 can be sequentially placed in the inner cavity of the shell 02, and each part can be locked and sealed by a reduced diameter tool. For example, the inner core 05 can be made of metal; the flow channel assembly 04 can be made of cast aluminum; the bottom bowl assembly 01 can be made of rubber; the protective cover 06 can be made of plastic; and the shell 02 can be made of cast aluminum.

[0091] As shown in Figure 6 some embodiments, the inner core 05 and the rubber main spring 03 can form an integral structure through a high-temperature vulcanization process, that is, a rubber inner core assembly. It should be noted that the high-temperature vulcanization process can be a conventional process, which will not be described in detail here.

[0092] Optionally, the inner core 05 can be provided with a filling hole through which damping liquid can be filled into the hydraulic suspension. In addition, a liquid sealing steel ball can be installed at the filling hole. In addition, the rubber main spring 03 can be provided with an inner cavity, which is arranged towards the flow channel assembly 04, so that the rubber main spring 03 and the flow channel assembly 04 form a first liquid chamber M, and the filling hole is in communication with the first liquid chamber M, so as to facilitate the filling of damping liquid into the first liquid chamber M. It should be noted that the specific structure and function of the inner core 05 and the structure and function of the rubber main spring 03 can also be referred to other related technologies, which will not be described in detail here.

[0093] Optionally, the flow channel assembly 04 can include a flow channel plate and a decoupling film, the flow channel plate is provided with an inertia passage, and the decoupling film is arranged on the flow channel plate and corresponds to the inertia passage. It should be noted that the specific structure and function of the flow channel assembly 04 can also be referred to other related technologies, which will not be described in detail here.

[0094] Optionally, the protective cover 06 can shield and protect the bottom bowl assembly 01 to prevent the bottom bowl assembly 01 from being damaged by external force impact and causing damping liquid leakage.

[0095] In the embodiment of the application, the outer circumferential surface of the first annular wall 111 and the inner wall of the shell 02 can have a gap, so that the first annular groove 11 and the second liquid chamber N can be in communication through the gap. In this way, the damping liquid in the second liquid chamber N can flow into the first annular groove 11 through the gap, so as to generate liquid pressure in the first annular groove 11, deform the second annular wall 112 towards the direction away from the first annular wall 111, and make the outer circumferential surface of the second annular wall 112 abut against the inner wall of the shell 02, thereby forming a seal at the second annular wall 112 to prevent damping liquid from leaking from the second annular wall 112.

[0096] Based on the above arrangement, the damping liquid can be injected into the first liquid chamber M through the filling hole of the inner core 05, and enter the second liquid chamber N through the inertia channel of the flow channel assembly 04, until the second liquid chamber N is filled with damping liquid. At this time, as the damping liquid continues to be filled, the pressure in the second liquid chamber N increases; the damping liquid in the second liquid chamber N enters the first annular groove 11 along the gap between the outer circumferential surface of the first annular wall 111 and the inner wall of the shell 02.

[0097] When the first annular groove 11 is filled with damping liquid, as the damping liquid continues to be filled, the damping liquid in the first annular groove 11 will extrude the inner side surface of the second annular wall 112, causing the second annular wall 112 to deform and tightly fit against the inner wall of the shell 02, thereby achieving a better sealing effect to prevent leakage of the damping liquid. It should be noted that the cooperation of the bottom bowl body 10 and the shell 02 can achieve a primary sealing effect, and the tight fit of the second annular wall 112 and the inner wall of the shell 02 can achieve a secondary sealing effect.

[0098] It should be noted that in the case of filling damping liquid, the interior of the hydraulic suspension can have a certain degree of vacuum, and under the action of vacuum pressure, the damping liquid can enter the first liquid chamber M along the filling channel. Of course, the damping liquid can also be pressed into the first liquid chamber M by external pressure.

[0099] To prevent the damping liquid from leaking between the outer circumferential surface of the second annular wall 112 and the inner wall of the shell 02, the outer wall of the bottom bowl body 10 can also be provided with a second annular groove 12, as shown in Figure 4 and Figure 8 The second annular groove 12 can include a third annular wall 121 and a fourth annular wall 122 spaced along the axial direction of the bottom bowl body 10. The specific structure and arrangement of the second annular groove 12, the third annular wall 121 and the fourth annular wall 122 can be referred to the related contents of the above-mentioned bottom bowl assembly 01, which will not be repeated here.

[0100] Since the second annular wall 112 and the third annular wall 121 can be the same annular wall, under the extrusion of the damping liquid in the first annular groove 11, the third annular wall 121 can deform towards the first annular wall 111, so that the outer circumferential surface of the third annular wall 121 tightly fits against the inner wall of the shell 02, thereby achieving a sealing effect.

[0101] However, as the pressure in the first annular groove 11 increases, the outer circumferential surface of the third annular wall 121 can leak the damping liquid to the inner wall of the housing 02, and as the hydraulic mount is used for a long time, the leakage flow of the damping liquid increases, so that the damping liquid in the second annular groove 12 increases, thereby increasing the pressure in the second annular groove 12. Thus, the fourth annular wall 122 can be deformed by the damping liquid in the second annular groove 12, so that the outer circumferential surface of the fourth annular wall 122 abuts against the inner wall of the housing 02, thereby further achieving the sealing effect.

[0102] Reference Figure 4 And Figure 8 In some embodiments, the outer wall of the bottom bowl body 10 can further be provided with a third annular groove 13, which can include a fifth annular wall 131 and a sixth annular wall 132 spaced along the axial direction of the bottom bowl body 10. The specific structure and arrangement of the third annular groove 13, the fifth annular wall 131 and the sixth annular wall 132 can be referred to the related contents of the bottom bowl assembly 01 described above, which will not be repeated here. Exemplarily, the third annular groove 13 can be one or more.

[0103] In order to be able to introduce pressure gas into the third annular groove 13, the side wall of the housing 02 can be provided with a through hole communicating with the third annular groove 13, for introducing pressure gas into the third annular groove 13 to deform the fifth annular wall 131 and abut against the inner wall of the housing 02.

[0104] Optionally, the pressure gas introduced into the third annular groove 13 through the through hole can increase the pressure in the third annular groove 13, and the gas pressure can extrude the fifth annular wall 131 to deform away from the sixth annular wall 132, so that the outer circumferential surface of the fifth annular wall 131 abuts against the inner wall of the housing 02 to achieve the sealing effect.

[0105] When the pressure in the third annular groove 13 is relatively large, the pressure gas can leak through the outer circumferential surface of the fifth annular wall 131 to the first annular groove 11 or the second annular groove 12, so as to be opposed to the damping liquid at the second annular wall 112 or the fourth annular wall 122 to form a gas seal, thereby preventing the damping liquid from leaking.

[0106] In order to realize the installation of the support skeleton 20, the outer wall of the bottom bowl body 10 can further be provided with a fourth annular groove 14 between the second annular groove 12 and the third annular groove 13. The specific structure and arrangement of the fourth annular groove 14 can be referred to the related contents of the bottom bowl assembly 01 described above, which will not be repeated here.

[0107] The fourth ring groove 14 and the second ring groove 12 can share a fourth ring wall 122, and the fourth ring groove 14 and the third ring groove 13 can share a fifth ring wall 131. In this way, when pressure gas is introduced into the third ring groove 13, the pressure gas can leak to the fourth ring groove 14 through the fifth ring wall 131 and the inner wall of the shell 02. As the gas pressure in the fourth ring groove 14 increases, the pressure gas can form a gas seal at the fourth ring wall 122 to prevent the damping liquid from leaking between the fourth ring wall 122 and the inner wall of the shell 02.

[0108] Based on the above-mentioned hydraulic suspension, the embodiments of the present application also disclose an automobile. The disclosed automobile comprises the above-mentioned hydraulic suspension.
