[0066] The following detailed description will further describe the present application with reference to the above mentioned figures. DETAILED DESCRIPTION
[0067] The following description will further describe the present application with reference to the above mentioned figures. Shown in the drawings are exemplary embodiments of the present application. However, the present application can be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art. Like reference numerals refer to like or similar components throughout. The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that "comprising" is used in the description or the claims, it is intended to be taken in its broadest possible way and should be interpreted in the same way as "including" and / or "containing" and / or "having". To the extent that it is used in the description or the claims, "including" and / or "containing" and / or "having" should be construed to be open-ended and not limiting. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
[0068] Generally, the damper support, as one of the key components for load transmission, can mitigate the impact by exerting the elastic effect of the elastic element. In one possible implementation, the damper support is configured to be connected with the piston rod and provide buffering for the movement of the piston rod; the damper support generally has a limiting element (e.g., a shell) and an elastic element, the limiting element wraps the elastic element and limits it, so that the elastic element can continuously provide buffering for the piston rod during the reciprocating movement of the piston rod.
[0069] However, when the elastic element moves to the limit position in the axial direction, a gap may be generated between the elastic element and the limiting element and an abnormal sound may be emitted. In order to solve this problem, a high-low relief surface feature (e.g., a wavy surface feature) can be provided on the side of the limiting element for contacting the elastic element, so as to avoid the generation of a gap between the elastic element and the limiting element at the limit position as much as possible, so as to further mitigate or even eliminate the abnormal sound.
[0070] However, due to the different heights of the wave-shaped surface features in the axial direction (it can be understood that the surface features present a continuous wave shape on the surface of the limiting element, and the wave shape corresponds to the wave peaks and wave troughs arranged at intervals, so that the wave-shaped surface features have different heights in the axial direction), the elastic element in contact with the wave-shaped surface features is unevenly stressed in different radial directions (for example, the part of the elastic element in contact with the wave peak is unevenly stressed relative to the part of the elastic element in contact with the wave trough); Furthermore, when the upper and lower surfaces of the elastic element are provided with the wave-shaped surface features in the axial direction at the same time, due to the difficulty or even the inability of the two wave-shaped surface features on the upper and lower surfaces to completely match (especially when the rotation of the cover plate during the spin riveting process is not controlled), the shape of the upper and lower matching surfaces of the elastic element is not controlled, which further causes the elastic element to be more unevenly stressed in different radial directions. This will result in low stability of the elastic element, and the elastic element will be damaged due to easy local material fatigue, reducing the overall durability of the elastic element.
[0071] Correspondingly, the application provides a shock absorber support, a shock absorber assembly and a vehicle. The shock absorber support includes a buffer and a shell; the buffer is configured to provide a buffering force in an axial direction; the shell includes a first surface and a second surface, the buffer is clamped between the first surface and the second surface in the axial direction, and the first surface and / or the second surface has a surface configuration configured to contact and cooperate with the buffer; the shock absorber support defines a movement axis extending in the axial direction, and the surface configuration is rotationally symmetric about the movement axis. The shock absorber assembly includes a shock absorber body and the shock absorber support as described above, and the shock absorber body is connected to the shock absorber support. The vehicle includes a main body, and also includes the shock absorber support or the shock absorber assembly as described above.
[0072] Further, the shock absorber support provided by the embodiments of the application includes a buffer and a shell, the buffer can provide a buffering force in an axial direction for buffering, the shell includes a first surface and a second surface spaced apart and clamping the buffer in the axial direction, for cooperating with the buffer to continuously provide buffering. The shock absorber support defines a movement axis extending in the axial direction, which can be the main movement trajectory line of the piston rod connected to the shock absorber support reciprocating in the axial direction, and the surface configuration in contact and cooperation with the buffer is rotationally symmetric about the movement axis, so that the buffer is uniformly stressed in different radial directions, improving the stability and durability of the shock absorber support.
[0073] The following description will be made with reference to the accompanying drawings. It should be noted that the components depicted in the accompanying drawings are not necessarily shown to scale; and identical or similar components will be given the same or similar reference numerals or similar technical terms.
[0074] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
[0075] As shown in Figures 1 to 3 embodiments of the present application provides a damper support 10, which comprises a buffer 12, a shell 11 and a connecting block 13, wherein the shell 11 comprises a detachable cover 112 and a shell body 111. The cover 112 and the shell body 111 cooperate to form a containing space 1110, and the buffer 12 is arranged in the containing space 1110. The connecting block 13 is connected with the buffer 12, and the connecting block 13 is configured to be spaced apart from the shell 11. The damper support 10 is used to cooperate with a piston rod 181 (as shown in Figure 7 connecting block 13 is used to connect with the piston rod 181, and the piston rod 181 is buffered by the buffer 12 through the connecting block 13. The shell 11 can limit the buffer 12.
[0076] In an embodiment, the damper support 10 defines a movement axis F extending along an axial direction L, and the movement axis F penetrates the shell 11 and the buffer 12 along the axial direction L. The buffer 12 is configured to provide a buffering force along the axial direction L; the shell 11 comprises a first surface 1121 and a second surface 1112, and the buffer 12 is clamped between the first surface 1121 and the second surface 1112 along the axial direction L. The first surface 1121 and / or the second surface 1112 has a surface configuration 110 configured to contact and cooperate with the buffer 12; and the surface configuration 110 is rotationally symmetrical about the movement axis F.
[0077] It can be understood that the damper support 10 provided by the embodiments of the present application comprises a buffer 12 and a shell 11. The buffer 12 can provide a buffering force along the axial direction L to achieve buffering. The shell 11 comprises a first surface 1121 and a second surface 1112 spaced apart along the axial direction L and clamping the buffer 12, and continuously providing buffering by cooperating with the buffer 12. The damper support 10 defines a movement axis F extending along the axial direction L, and the movement axis F can be the main movement trajectory (i.e., the main axis) of the piston rod 181 connected with the damper support 10 reciprocating along the axial direction L. The surface configuration 110 in contact with the buffer 12 is rotationally symmetrical about the movement axis F, so that the buffer 12 is uniformly stressed along different radial directions R, thereby improving the stability and durability of the damper support 10.
[0078] It can be understood that the damper support 10 is generally designed to cooperate with the piston rod 181 to achieve damping, and the piston rod 181 is generally designed to reciprocate along a straight line (main axis) (the complex changes in the actual working condition are not discussed here), that is, the movement axis F, which penetrates the shell 11 and the buffer 12 along the axial direction L. Cooperating with it, the movement axis F can be used as a reference line of the damper support 10, and the positional relationship and structural features of each component in the damper support 10 are described based on the reference line, so that the skilled in the art can better understand the present application.
[0079] In the embodiment, the axial direction L is the extension direction of the movement axis F, and the radial direction R is one or more directions in the plane perpendicular to the axial direction L.
[0080] In the embodiment, the shell 111 has a semi-enclosed configuration, and the cover 112 is generally plate-shaped and covers one side of the semi-enclosed shell 111. The first surface 1121 is provided on the cover 112, and the second surface 1112 is provided on the shell 111. The first surface 1121 and the second surface 1112 are spaced apart along the axial direction L. The shell 111 further includes a third surface 1113 located between the first surface 1121 and the second surface 1112 along the axial direction L. The first surface 1121, the second surface 1112, and the third surface 1113 are arranged around the accommodation space 1110.
[0081] In the embodiment, the buffer 12 is circular ring-shaped. The buffer 12 includes an upper surface 121 and a lower surface 122 spaced apart along the axial direction L. The upper surface 121 is in contact with the first surface 1121, and the lower surface 122 is in contact with the second surface 1112. The buffer 12 further includes an outer surface 123 and an inner surface 124. The outer surface 123 is located on the outer side of the circular ring-shaped buffer 12 along the radial direction R, and the inner surface 124 is located on the inner side of the circular ring-shaped buffer 12 along the radial direction R. The outer surface 123 is in contact with the third surface 1113. The inner surface 124 is configured not to be in contact with the shell 11 when the buffer 12 does not deform, and to be in contact with the shell 11 when the buffer 12 deforms.
[0082] In the embodiment, the connecting block 13 is configured to be located between the first surface 1121 and the second surface 1112 along the axial direction L and to be connected to the middle part of the buffer 12. The connecting block 13 is generally plate-shaped and is arranged in parallel with a plane (symmetry plane P) perpendicular to the axial direction L. The connecting block 13 is provided with a through hole 130 penetrating along the axial direction L. The connecting block 13 can be fixed with the piston rod 181 by a locking member (not shown, such as a nut). The connecting block 13 is driven by the piston rod 181 to move along the axial direction L to press the buffer 12.
[0083] In the embodiment, the buffer 12 is made of elastic material, such as polyurethane. The buffer 12 has the property of being deformed under compression and absorbing impact and / or providing a counteracting buffer force by being deformed, thereby achieving shock absorption and buffering. In other embodiments, the buffer 12 can also be made of other materials and / or structures capable of providing a buffer force, or be polyurethane with specific parameter indexes, which are not described herein.
[0084] In an embodiment, the first surface 1121 and the second surface 1112 are both provided with the surface configuration 110.
[0085] In the embodiment, the first surface 1121 and the second surface 1112 are provided with the same surface configuration 110. In other embodiments, the surface configuration 110 provided on the first surface 1121 and the surface configuration 110 provided on the second surface 1112 can also have different structures, but the surface configuration 110 provided on the first surface 1121 and the surface configuration 110 provided on the second surface 1112 should both be rotationally symmetrical about the movement axis F.
[0086] It can be understood that the buffer 12 can provide buffering along the axial direction L, and in the process of providing buffering, the upper surface 121 and the lower surface 122 of the buffer 12 can both have a gap with the shell 11 and cause abnormal sound. The surface configuration 110 provided on the first surface 1121 and the second surface 1112 which are in contact with the buffer 12 along the axial direction L respectively can further improve the abnormal sound problem.
[0087] In an embodiment, the surface configuration 110 provided on the first surface 1121 and the surface configuration 110 provided on the second surface 1112 are symmetrically arranged about a plane (symmetry plane P) perpendicular to the axial direction L.
[0088] In the embodiment, the plane perpendicular to the axial direction L is defined as the symmetry plane P, and the buffer 12 can have a substantially symmetrical structure about the symmetry plane P, or it can be understood that the buffer 12 can have a substantially symmetrical thickness about the symmetry plane P. The symmetry plane P is located between the first surface 1121 and the second surface 1112 along the axial direction L, and the surface configuration 110 provided on the first surface 1121 and the surface configuration 110 provided on the second surface 1112 are symmetrically arranged about the symmetry plane P.
[0089] It can be understood that the two surface configurations 110 arranged on both sides of the buffer 12 along the axial direction L are symmetrically arranged about the symmetry plane P perpendicular to the axial direction L, and the surface configuration 110 itself is rotationally symmetric about the movement axis F. Based on this, even if the first surface 1121 and the second surface 1112 are simultaneously provided on the surface configuration 110, the force of the buffer 12 along different radial directions R can be substantially uniform; and even if the first surface 1121 and the second surface 1112 are configured to be rotatable about the movement axis F, the surface configuration 110 which is rotationally symmetric about the movement axis F can still ensure that the force of the buffer 12 along different radial directions R is substantially uniform after rotation, thereby improving the stability and durability of the shock absorber support 10.
[0090] Further combining Figures 3 to 6 As shown, in an embodiment, the shell 11 is provided with a mounting hole 113 penetrating through the first surface 1121 and the second surface 1112 along the axial direction L, and the buffer 12 is provided with an avoidance hole 120 penetratingly arranged along the axial direction L. The mounting hole 113 and the avoidance hole 120 are in communication along the axial direction L, the movement axis F passes through the mounting hole 113 and the avoidance hole 120, and the aperture of the avoidance hole 120 along the radial direction R is greater than the aperture of the mounting hole 113 along the radial direction R.
[0091] In the present embodiment, the mounting hole 113 includes a first mounting hole 1131 and a second mounting hole 1132, the first mounting hole 1131 penetrates through the cover 112 along the axial direction L, and the second mounting hole 1132 penetrates through the shell 111 along the axial direction L; the avoidance hole 120 penetrates through the buffer 12 along the axial direction L; and the connecting block 13 is provided with a through hole 130 penetratingly arranged along the axial direction L. The first mounting hole 1131, the avoidance hole 120, and the second mounting hole 1132 are sequentially arranged along the axial direction L, and the through hole 130 is substantially located in the middle of the avoidance hole 120, which cooperates to realize the mounting of the piston rod 181, and the mounted piston rod 181 is arranged to extend along the axial direction L.
[0092] It can be understood that the mounting hole 113 and the avoidance hole 120 are used for the mounting and / or avoidance of the piston rod 181, the aperture of the avoidance hole 120 is greater than the aperture of the mounting hole 113, and a deformation gap can be formed between the inner surface 124 of the buffer 12 and the piston rod 181, so that the buffer 12 can move towards the space where the deformation gap is located to complete the deformation when the buffer 12 is deformed under pressure.
[0093] In an embodiment, the surface configuration 110 includes a first protrusion 1101 and a second protrusion 1102 arranged at intervals along the radial direction R, and a recessed region 1103 arranged on both sides of the first protrusion 1101 along the radial direction R. The first protrusion 1101 and the second protrusion 1102 are both protruded towards the region where the accommodation space 1110 is located, and the recessed region 1103 has a height difference with the first protrusion 1101 and the second protrusion 1102 along the axial direction L. The upper surface 121 of the buffer 12 is configured to be in contact with the first surface 1121 provided with the surface configuration 110, and the lower surface 122 of the buffer 12 is configured to be in contact with the second surface 1112 provided with the surface configuration 110.
[0094] In an embodiment, the surface configuration 110 includes a first protrusion 1101 in the shape of a circular ring. The first protrusion 1101 is rotationally symmetrical about the movement axis F, the first protrusion 1101 is protruded towards the buffer 12 along the axial direction L, and the first protrusion 1101 is configured to be in contact with the buffer 12.
[0095] It can be understood that the first protrusion 1101 is protruded towards the buffer 12 along the axial direction L and can be in contact with the buffer 12, and the periphery of the protruded first protrusion 1101 necessarily has a corresponding recessed region 1103, so that the buffer 12 can be in contact with a first surface 1121 and / or a second surface 1112 which is not completely flat in general, thereby avoiding the generation of abnormal sound. At the same time, the first protrusion 1101 in the shape of a circular ring and rotationally symmetrical about the movement axis F has better rotational symmetry characteristics, which can ensure that the force received by the buffer 12 along different radial directions R is substantially uniform, thereby improving the stability and durability of the shock absorber support 10.
[0096] In an embodiment, the second protrusion 1102 is arranged around the mounting hole 113, the second protrusion 1102 is arranged protruded towards the side where the buffer 12 is located along the axial direction L, and the second protrusion 1102 is configured to be in separable contact with the buffer 12.
[0097] In the present embodiment, when the buffer 12 is not deformed, the second protrusion 1102 is not in contact with the buffer 12. When the buffer 12 is deformed, since the upper surface 121, the lower surface 122 and the outer surface 123 of the buffer 12 are all limited, the deformed buffer 12 will be inclined and extruded towards the side of the inner surface 124, and the extruded inner surface 124 will be in contact with the second protrusion 1102, thereby limiting the buffer 12 by the second protrusion 1102.
[0098] In the present embodiment, the top end of the first protrusion 1101 and the second protrusion 1102 both have arc-shaped guide surfaces, which can prevent the buffer 12 from being torn when in contact with the first protrusion 1101 and the second protrusion 1102, and can prevent the surface of the buffer 12 from being damaged.
[0099] It can be understood that the second boss 1102 is arranged around the mounting hole 113, and specifically, the second boss 1102 is arranged around the outer side periphery of the mounting hole 113. On the one hand, the radial deformation of the buffer piece 12 under pressure can be reduced, local material fatigue caused by excessive local deformation can be avoided, and local fatigue fracture can be further avoided, the overall durability of the buffer piece 12 is improved, and the durability of the shock absorber support 10 is improved. On the other hand, the buffer piece 12 can be prevented from being cut by the sharp edge of the cover 112 or the shell 111, especially to prevent the surface of the buffer piece 12 from being damaged, improve the overall durability of the buffer piece 12, and improve the durability of the shock absorber support 10.
[0100] In an embodiment, when the buffer piece 12 is arranged in the accommodation space 1110, the first boss 1101 and the second boss 1102 are protruded towards the buffer piece 12 along the axial direction L. The second boss 1102 is arranged around the periphery of the mounting hole 113, and the first boss 1101 is arranged on the side of the second boss 1102 away from the mounting hole 113.
[0101] It can be understood that when the buffer piece 12 is arranged in the accommodation space 1110, the buffer piece 12 is more inclined to be arranged away from the mounting hole 113 in the diastolic state to reserve enough deformation space. The first boss 1101 is located away from the mounting hole 113, and the first boss 1101 is configured to abut against the buffer piece 12. The buffer piece 12 can abut against and contact the first boss 1101 in the diastolic state and the compressed state, thereby avoiding abnormal sound. The second boss 1102 is arranged around the mounting hole 113, and the buffer piece 12 can be deformed and contacted with the second boss 1102 in the compressed state. The protruding second boss 1102 can also be used to avoid abnormal sound, and the second boss 1102 can also limit the buffer piece 12 to avoid local material fatigue. The buffer piece 12 is separated from the second boss 1102 in the diastolic state, thereby providing deformation space for the buffer piece 12.
[0102] Further combined Figures 4 to 6 As shown, in an embodiment, the shell 11 includes a cover 112 and a shell 111, and the buffer piece 12 is clamped between the cover 112 and the shell 111 along the axial direction L. The cover 112 and the shell 111 are rotatably connected, and / or the cover 112 and the shell 111 are detachably connected.
[0103] It can be understood that the cover 112 and the shell 111 are arranged in a split manner to facilitate manufacturing and installation of the buffer piece 12. The cover 112 and the shell 111 are rotatably connected, which facilitates assembly of the cover 112 and the shell 111 by a spin riveting process. At the same time, the surface configuration 110 has the characteristic of rotational symmetry about the movement axis F, and the installation of the cover 112 and the shell 111 will not cause the buffer piece 12 to be unevenly stressed along each radial direction R. The shock absorber support 10 has good stability and durability as a whole.
[0104] In an embodiment, the housing 111 is provided with a mounting groove 1111 on a side thereof away from the cushion 12 along the axial direction L, the mounting groove 1111 is arranged around the inner wall of the housing 111, and the housing 111 is provided with a limiting plate 1115 at the top end of the mounting groove 1111 away from the mounting groove 1111 along the axial direction L. The edge of the cover 112 is provided with a mounting end 1124 which is shaped to match the mounting groove 1111, and the mounting end 1124 is rotatably arranged in the mounting groove 1111, and the limiting plate 1115 and the mounting end 1124 are arranged in a stack along the axial direction L to prevent the cover 112 from being detached.
[0105] In an embodiment, the cover 112 comprises a first abutting surface 1123, and the housing 111 comprises a second abutting surface 1114, the first abutting surface 1123 and the second abutting surface 1114 are configured to abut each other. The second abutting surface 1114 is located on the side of the first abutting surface 1123 away from the cushion 12 along the axial direction L, and the first abutting surface 1123 and the second abutting surface 1114 are both perpendicular to the movement axis F.
[0106] In the present embodiment, the first abutting surface 1123 is a surface for abutting with the limiting plate 1115, and the second abutting surface 1114 is a surface for abutting with the mounting end 1124. The first abutting surface 1123 is configured as a flat surface rather than an inclined surface as in the conventional structure, and the second abutting surface 1114 matched with the first abutting surface 1123 is also configured as a flat surface, so as to increase the contact area of the first surface 1121 and the second surface 1112 along the radial direction R, thereby increasing the support strength, reducing the risk of relative displacement of the cover 112 and the housing 111 along the axial direction L under external pressure, and making the cover 112 have a more stable assembly relationship with the housing 111.
[0107] It can be understood that, compared with the structure in which the first abutting surface 1123 and the second abutting surface 1114 are inclined to each other in the general structure, the contact area between the first abutting surface 1123 and the second abutting surface 1114 in the present application is significantly increased. When the cover 112 is subjected to external pressure and has a tendency to separate from the housing 111, the housing 111 can provide better support for the cover 112, thereby effectively blocking the tendency of the cover 112 to continue moving in the original direction, reducing the risk of deformation of the cover 112 and the amount of deformation that may occur, making the assembly relationship between the cover 112 and the housing 111 not easy to change, and keeping the cover 112 and the housing 111 in close contact as much as possible, reducing the probability of gap generation and the risk of abnormal sound.
[0108] In an embodiment, the housing 111 further comprises a connecting end 1116 for connecting with the vehicle body 21 of the vehicle 2 and / or the damping main body 18 of the damper assembly 1.
[0109] In the embodiment, the shell 111 comprises two connecting ends 1116, which are arranged at opposite sides of the shell 111. It can be understood by those skilled in the art that the number, position, and twist angle of the connecting ends 1116 can be adjusted according to the specific assembly relationship, which will not be described here.
[0110] Further combining Figure 7 As shown, the embodiment of the present application also provides a shock absorber assembly 1. The shock absorber assembly 1 comprises a shock absorber body 18 and the shock absorber support 10 according to any one of the preceding embodiments, and the shock absorber body 18 is connected to the shock absorber support 10.
[0111] In the embodiment, the shock absorber body 18 comprises a piston rod 181 and a shock absorbing component 182, and the piston rod 181 and / or the shock absorbing component 182 are connected to the shock absorber support 10, and the shock absorber support 10 is arranged at the end of the shock absorber body 18. The shock absorbing component 182 can be a spring (specifically a compression spring), or a hydraulic device, or an air damper, or an electromagnetic damper, etc., which will not be described here.
[0112] Further combining Figure 8 As shown, the embodiment of the present application also provides a vehicle 2, which comprises a main body 20, and further comprises the shock absorber support 10 according to any one of the preceding embodiments or the shock absorber assembly 1 according to the preceding embodiments.
[0113] In the embodiment, the main body 20 comprises a vehicle body 21 and a vehicle wheel 22, and the shock absorber assembly 1 is connected between the vehicle body 21 and the vehicle wheel 22, and is used to filter the bumps during the driving of the vehicle 2. In the embodiment, the shock absorber assembly 1 is taken as the rear shock absorber of the vehicle 2 as an example, and in other embodiments, the shock absorber assembly 1 comprising the shock absorber support 10 can also be taken as the front shock absorber of the vehicle 2, or as other shock absorbing structures, which will not be described here.
[0114] The shock absorber assembly 1 and the vehicle 2 of the present application apply the shock absorber support 10 described above, which has good stability and durability, and is not prone to abnormal noise.
