In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] The present embodiment relates to a suspension structure to solve the problem in the prior art that the suspension structure is easily damaged by heat and has poor durability when arranged close to a heat source.

[0048] In terms of overall structure, the suspension structure includes a suspension body and a cover body 2; the suspension body includes a shell 1, a main spring 3 disposed in the shell 1, and an inner core 4 connected to the main spring 3, and part of the inner core 4 passes through the shell 1. The cover body 2 is disposed outside the shell 1, and a through hole 203 is provided on the cover body 2 for the inner core 4 to pass through, and a hook structure is provided between the cover body 2 and the shell 1, and the cover body 2 is connected to the shell 1 through the hook structure.

[0049] The suspension structure described in this embodiment, by arranging the main spring 3 in the shell 1 and arranging a cover body 2 outside the shell 1, is beneficial for the suspension structure to avoid the risk of heat damage, reduce the transfer of heat from the heat source to the main spring 3, and further help improve the durability of the suspension structure. The cover body 2 is connected to the shell 1 by a hook structure, which is convenient for the installation of the cover body 2 on the shell 1.

[0050] Based on the above overall introduction, an exemplary structure of the suspension structure described in this embodiment is as follows: Figures 1 to 5 As shown in FIG. 1 , the housing 1 is used as a mounting carrier for the entire suspension structure. Figure 6As shown in , the housing 1 includes a first housing 101 and a second housing 102 connected by rivets. The main spring 3 is connected to the first housing 101 and the inner core 4, the second housing 102 is provided with a through hole 1027 corresponding to the through hole 203, and the cover 2 is covered on the second housing 102. Here, the first housing 101 and the second housing 102 are connected by rivets, which has the advantages of simple assembly and stable connection effect. The cover 2 is arranged on the second housing 102, which is conducive to heat insulation protection of the suspension structure.

[0051] In this embodiment, the structures of the first housing 101 and the second housing 101 are as follows: Figures 7 to 9 As shown in , the first shell 101 and the second shell 102 are hollow inside, and both the first shell 101 and the second shell 102 are arranged along the axial direction of the main spring 3, and a cavity with two ends open is formed between the first shell 101 and the second shell 102, and the main spring 3 is specifically located in the cavity. The first shell 101 is provided with a first mounting plate 1011 extending outward, and the second shell 102 is provided with a second mounting plate 1021 arranged corresponding to the first mounting plate 1011.

[0052] The first mounting plate 1011 is provided with a first mounting hole 1012, and the second mounting plate 1021 is provided with a second mounting hole 1022 corresponding to the first mounting hole 1012. The suspension structure can be installed on the external carrier by a second fastener inserted into the first mounting hole 1012 and the second mounting hole 1022. To facilitate the distinction from the external carrier described below, the external carrier connected to the second fastener is referred to as the first external carrier. The structure of providing the first mounting plate 1011 and the second mounting plate 1021, and providing mounting holes on both of them is simple, easy to process and form, and is conducive to installing the suspension structure on the first external carrier.

[0053] Specifically, refer to Figures 6 to 8 As shown in , the first mounting plate 1011 in this embodiment is arranged at one end of the first housing 101 close to the second housing 102, and the first mounting plates 1011 are arranged on both sides of the first housing 101. The second mounting plates 1021 are arranged at one end of the second housing 102 close to the first housing 101, and are arranged on both sides of the second housing 102 corresponding to each first mounting plate 1011. The first mounting plate 1011 and the corresponding second mounting plate 1021 are installed on the first external carrier through the second fastener, and have good installation stability. Of course, in the specific implementation, the number of the first mounting plates 1011 can also be adaptively adjusted according to the use requirements, and at this time, the second mounting plates 1021 can be arranged corresponding to the first mounting plates 1011.

[0054] To further improve the mounting reliability of the housing 1 on the first external carrier, as Figure 7 and Figure 8As shown in the figure, the first mounting holes 1012 are two spaced apart at the end of the first mounting plate 1011 along the width direction of the first mounting plate 1011. The second mounting holes 1022 are arranged one-to-one correspondingly to the first mounting holes 1012. That is, the first mounting plate 1011 and the second mounting plate 1021 located on the same side are specifically mounted on the first external carrier through two second fasteners.

[0055] It is understandable that the position and number of the first mounting holes 1012 can also be adjusted according to the use requirements, and the second mounting holes 1022 can be arranged correspondingly to the first mounting holes 1012. The second fastener in this embodiment can be a bolt and a nut threadedly connected with the bolt, which has the advantages of easy operation, installation and removal. The first external carrier in this embodiment can be, for example, a frame on a vehicle.

[0056] In order to facilitate the riveting of the first shell 101 and the second shell 102, the second shell 102 is provided with rivets 1023 for riveting with the first shell 101. Figures 6 to 8 As shown in FIG. 1 , two rivets 1023 are arranged at intervals along the width direction of the second mounting plate 1021 at one end close to the main spring 3, and rivet holes 1013 corresponding to the rivets 1023 are arranged on the first mounting plate 1011. The first housing 101 and the second housing 102 are connected together by riveting the rivets 1023 to the corresponding rivet holes 1013.

[0057] It is understandable that the number and position of the rivets 1023 can also be adjusted according to the use requirements, and the rivet holes 1013 and the rivets 1023 can be arranged one by one. In addition, it is also feasible to arrange the rivets 1023 on the first mounting plate 1011 and the rivet holes 1013 on the second mounting plate 1021.

[0058] In this embodiment, the structure of the cover body 2 is as follows Fig.10 and Fig.11 As shown in the figure, the shape of the cover body 2 is arranged in accordance with the shape of the second shell 102, which is conducive to improving the covering effect of the cover body 2 on the second shell 102. For example, the cross-sections of the cover body 2 and the second shell 102 are both circular as shown in the figure, which is conducive to improving the installation effect of the cover body 2. In addition, the cover body 2 is made of rubber, which has the advantages of easy implementation and good heat insulation effect. At the same time, the cover body 2 made of rubber is also conducive to hooking on the second shell 102. For example, the cover body 2 can be made of EPDM.

[0059] As a preferred embodiment, the hook structure in this embodiment includes a hook ear 201 provided on the cover body 2, and a hook 1024 provided on the shell 1, and the hook ear 201 is provided with a hook hole 202 for hooking the hook 1024. Here, the hook hole 202 on the hook ear 201 cooperates with the hook 1024 on the shell 1 to achieve a good hooking effect, and the structure is simple, which is easy to arrange and implement.

[0060] For detailed structure, refer to Figures 8 to 11 As shown in the figure, the hook 1024 is specifically arranged at one end of the second shell 102 facing the first shell 101, and there are two hooks 1024 arranged opposite to each other on the outer periphery of the second shell 102. Each hook 1024 is located between the two second mounting plates 1021 in the circumferential direction of the second shell 102, which is conducive to the arrangement and implementation of the hook 1024. The hanging ear 201 is arranged at one end of the cover body 2 facing the first shell 101 corresponding to the hook 1024, and is extended in the direction close to the first shell 101. The entire hanging ear 201 and the hanging hole 202 thereon are both arc-shaped, so as to improve the hooking effect between the cover body 2 and the second shell 102.

[0061] In order to further improve the use effect of the hook 1024, each hook 1024 includes two hook 1024 parts arranged at intervals along the circumference of the second shell 102, and each hook 1024 part is "L"-shaped, and has a first part extending along the radial direction of the second shell 102, and a second part connected to the free end of the first part and extending toward the first shell 101 along the axial direction of the second shell 102. The cover body 2 covered on the second shell 102 can be installed on the second shell 102 by hooking the ear 201 on the corresponding hook 1024. In the hooked state, the second part is blocked on the outside of the ear 201, so as to prevent the ear 201 from being separated from the hook 1024 in the hooked state, thereby ensuring the installation stability of the cover body 2 on the second shell 102.

[0062] It should be noted that the number of hook 1024 segments in each hook 1024 can be adaptively increased or decreased according to usage requirements, and the shape of the hook 1024 segment is not limited to the "L" shape shown in the figure. During specific implementation, the shape of the hook 1024 segment only needs to meet the hooking requirements.

[0063] As a preferred embodiment, Fig.12 and Fig.16 As shown in FIG. 1 , the main spring 3 in this embodiment has a rubber-coated portion wrapped around the inner core 4. The rubber-coated portion is provided with a protrusion 304 protruding along the axial direction of the inner core 4, and the protrusion 304 is used to abut against the shell 1 to limit the axial displacement of the inner core 4. The setting of the protrusion 304 is conducive to bearing the axial force of the inner core 4 and can prevent the inner core 4 from directly colliding with the shell 1 to produce abnormal noise.

[0064] In this embodiment, the inner core 4 includes a main body 401 and a connector 402 disposed at one end of the main body 401. The connector 402 is in the shape of an elongated strip, and is provided with a plurality of first fasteners 404 arranged at intervals along its length direction. The main spring 3 and the inner core 4 are vulcanized, and the rubber-coated portion on the main spring 3 is arranged in accordance with the shape of the inner core 4. Among them, the processing of the main body 401 and the connector 402 is simple and easy to process and form. The connector 402 is in the shape of an elongated strip, and its cross section is rectangular, which is conducive to bearing the axial and radial forces along the inner core 4. Compared with the traditional circular connector 402, it has better durability. Multiple first fasteners 404 are used to connect to the second external carrier to attenuate the vibration between the first external carrier and the second external carrier through the suspension structure. The second external carrier here can be a powertrain, such as a transmission or an engine.

[0065] In terms of specific structure, Fig.13 and Fig.14 As shown in , the main body 401 includes a cylindrical portion 4012 and a conical portion 4011 disposed at one end of the cylindrical portion 4012, and the cylindrical portion 4012 is connected to the connector 402. The protrusion 304 is disposed corresponding to the end face of the cylindrical portion 4012 connected to the connector 402. Among them, the outer peripheral wall of the conical portion 4011 is conical, and the interior is hollow, and the conical portion 4011 is specifically located in the cavity in the first shell 101. In this embodiment, the structures of the cylindrical portion 4012, the conical portion 4011 and the connector 402 are simple, so that the cylindrical portion 4012 and the connector 402 are connected, and it is easy to arrange and implement. The protrusion 304 is disposed corresponding to the end face of the cylindrical portion 4012 and the connector 402, which is conducive to improving the limiting effect of the protrusion 304.

[0066] like Fig.15 and Fig.16 As shown in FIG. , the rubber-coated portion includes a first coating portion 301 coated outside the conical portion 4011, a second coating portion 302 coated outside the cylindrical portion 4012, and a third coating portion 303 coated outside the connecting body 402. Considering that the main spring 3 is vulcanized together with the first shell 101, the first shell 101 is arranged in the shape of the conical portion 4011, that is, the cross section of the first shell 101 is gradually reduced in the direction away from the second shell 102.

[0067] The cylindrical portion 4012 is specifically located in the second housing 102, and the connector 402 extends out of the second housing 102 and the through hole 203. In this embodiment, the through hole 1027 and the through hole 203 on the second housing 102 are rectangular in shape to match the cross section of the connector 402. There are gaps between the outer peripheral wall of the extension body and the inner peripheral walls of the through hole 1027 and the through hole 203, which is conducive to ensuring the performance of the suspension structure.

[0068] In addition, the two first fasteners 404 on the connector 402 can be spaced apart along the length direction of the connector 402, which is conducive to improving the connection reliability between the connector 402 and the second external carrier. The first fastener 404 can be a bolt, which has a simple structure and is easy to arrange and connect.

[0069] When implementing it, Fig.14 As shown in , a positioning groove 403 between two first fasteners 404 may be provided on the end surface of the connecting body 402 to facilitate positioning the suspension structure on the second external carrier, thereby facilitating the installation efficiency of the suspension structure. Moreover, the positioning groove 403 may also achieve a weight reduction effect.

[0070] The structure of the protrusion 304 is as follows Fig.16 As shown in , it is specifically located on both sides of the connector 402 in the width direction, which is conducive to further improving the stability of the protrusion 304 during use. A plurality of convex strips arranged at intervals are provided on the end surface of the protrusion 304. The protrusion 304 is specifically abutted against the second shell 102 through the plurality of convex strips, so that it can withstand the axial pulling pressure of the second shell 102, thereby helping to improve the performance of the suspension structure.

[0071] In order to further improve the performance of the cover body 2, Fig.11 As shown in , the cover body 2 is provided with a limiting protrusion 204 protruding outward along the opening direction of the through hole 203, and the limiting protrusion 204 is used to limit the displacement of the suspension structure along the axial direction of the inner core 4. By providing the limiting protrusion 204 on the cover body 2, when the first fastener 404 is installed on the second external carrier, the limiting protrusion 204 can be abutted against the second external carrier to limit the displacement of the suspension structure along the axial direction of the inner core 4 close to the second external carrier, thereby facilitating the installation effect of the suspension structure on the second external carrier. At the same time, compared with the traditional solution of providing a limiting pad on the protruding part of the inner core 4 for limiting, the setting of the limiting protrusion 204 has the advantages of simple structure and good limiting effect.

[0072] In terms of specific structure, the limiting protrusion 204 includes a main body portion 2041 with a circular outer contour, and a plurality of convex block portions 2042 provided on the end surface of the main body portion 2041, and the plurality of convex blocks are provided at intervals along the circumference of the cover body 2. The limiting protrusion 204 is specifically limited by the abutment of the plurality of convex block portions 2042 with the second external carrier. Here, the convex block portions 2042 are fan-shaped, and due to the provision of the through-holes 203, the shapes of the respective fan-shaped portions are irregular. Here, the plurality of convex block portions 2042 cooperate with the limiting area to limit the position, thereby having a better limiting and buffering effect. In addition, as Figure 8As shown in the figure, a clamping groove 1025 is provided on one side of the second mounting plate 1021 close to the first mounting plate 1011. The clamping groove 1025 is used for clamping by an external device to facilitate testing the riveting force of the rivet 1023. Therefore, the clamping groove 1025 is not only convenient for clamping by an external device, but also has the effect of reducing weight. In specific implementation, the groove body of the clamping groove 1025 can be trapezoidal, which is conducive to the entry of the clamping structure of the clamping device, thereby clamping the second housing 102.

[0073] In addition, the second housing 102 in this embodiment is made of cast aluminum, which is not only conducive to improving the mechanical properties of the second housing 102, but also conducive to the lightweight suspension structure. Compared with the second housing 102 made of cast aluminum, the rivet 1023 can be made of iron or steel with higher strength to improve the connection strength between the first housing 101 and the second housing 102. In addition, the rivet 1023 can be cast together with the second housing 102 to improve the connection reliability of the rivet 1023 on the second mounting plate 1021. Figure 8 As shown in , a plurality of weight-reducing grooves 1026 may be further provided on a side of the second mounting plate 1021 facing the first mounting plate 1011 to further reduce the weight of the second shell 102 , thereby facilitating lightweighting of the shell 1 .

[0074] In this embodiment, by optimizing the structure of the suspension structure, a cover body 2 with a heat insulating effect is provided, a limiting protrusion 204 is provided on the cover body 2 for limiting the movement of the suspension structure relative to the second external carrier, and a protrusion 304 is provided on the rubber-coated part for limiting the axial displacement of the inner core 4 relative to the second shell 102, which is beneficial to improving the reliability and durability of the suspension structure.

[0075] In addition, this embodiment also relates to a vehicle, on which the suspension structure as described above is provided. In a specific implementation, the suspension structure can be installed at a location with a suspension arrangement requirement, such as a transmission.

[0076] The vehicle described in this embodiment is helpful to improve the comfort of the vehicle by providing the above suspension structure.
