[0033] Reference below Figure 1-Figure 4 According to the bushing structure 100 of the embodiment of the utility model, a snap-in groove 211 is provided at the end of the core body 2, and the anti-collision component 4 is snap-fitted into the snap-in groove 211 to achieve the installation of the anti-collision component 4. The installation is simple and convenient, and the anti-collision component 4 can be axially limited to prevent the anti-collision component 4 from falling off and reducing the anti-collision effect of the bushing structure 100.

[0034] like Figure 1-Figure 4 As shown, a bushing structure 100 according to an embodiment of the present utility model comprises: an outer tube 1 , a core body 2 and an anti-collision member 4 .

[0035] The core body 2 is passed through the outer tube 1, and a main spring 3 is provided between the core body 2 and the outer tube 1. Specifically, in the present embodiment, the outer tube 1, the core body 2 and the main spring 3 can all be cylindrical structures, and are coaxially distributed as the outer tube 1, the main spring 3 and the core body 2 in sequence from the outer shape, wherein the three can be connected separately by an installation structure, or can be manufactured as one by a vulcanization process, the axial extension length of the core body 2 is greater than the axial extension length of the outer tube 1 and the main spring 3, and the core body 2, the outer tube 1 and the main spring 3 are symmetrically distributed along the axial center of the core body 2.

[0036] The outer wall of one end of the core body 2 is provided with a clamping groove 211, the anti-collision component 4 is sleeved outside the core body 2, and at least part of the anti-collision component 4 is clamped in the clamping groove 211 to limit the axial position with the core body 2, and the anti-collision component 4 is located at the end of the outer tube 1. In this way, the axial installation of the anti-collision component 4 is reliable, and the anti-collision component 4 is not easy to fall off when subjected to force, so as to effectively prevent the outer tube 1 from collision.

[0037] Specifically, a snap-in groove 211 is provided at one end of the core 2, and the snap-in groove 211 is located on the outer peripheral wall of the core 2. The anti-collision member 4 is installed on the outside of the core 2 through the snap-in groove 211. During actual installation, the anti-collision member 4 is installed along the axial direction of the core 2, and at least part of the anti-collision member 4 is snap-into the snap-in groove 211 to achieve snap-in installation of the anti-collision member 4 and the core 2, and the anti-collision member 4 is axially limited by the snap-in groove 211. In this way, the installation is stable and reliable, and the anti-collision member 4 can be prevented from falling off in the axial direction. The installation method is simple, and the assembly cost can be reduced. Among them, the snap-in groove 211 can be constructed as an annular groove, which is conducive to a firm snap-in with the anti-collision member 4. Among them, the anti-collision member 4 can be constructed as an anti-collision pad, and the anti-collision pad can be made of rubber material.

[0038] Thus, by snapping at least part of the anti-collision member 4 into the snap-fit ​​groove 211, the anti-collision member 4 can be limited in the axial direction of the core body 2, so as to prevent the anti-collision member 4 from losing its anti-collision function on the outer tube 1 after falling off, and further improve the stability of the bushing structure 100. The snap-fit ​​installation can simplify the assembly process of the anti-collision member 4 and improve work efficiency.

[0039] According to the bushing structure 100 of the embodiment of the utility model, the anti-collision component 4 can be axially limited by setting a snap-in groove 211 on the core body 2 to snap-fit ​​with the anti-collision component 4. The installation is reliable and can avoid falling off during transportation or vehicle assembly. The installation method is simple, which reduces the difficulty of assembly and thus reduces labor costs.

[0040] In some embodiments, the core body 2 includes a first inner core 21 and a second inner core 22 , the first inner core 21 is sleeved outside the second inner core 22 , and the snap-in groove 211 is provided outside the first inner core 21 .

[0041] Specifically, the core body 2 includes two parts, namely, a first inner core 21 and a second inner core 22, the first inner core 21 and the second inner core 22 are coaxially connected, and the first inner core 21 is sleeved outside the second inner core 22, wherein the first inner core 21 and the second inner core 22 can be integrally formed by vulcanization to ensure reliable installation of the first inner core 21 and the second inner core 22. The clamping groove 211 is provided on the outer peripheral wall of the first inner core 21, and the anti-collision member 4 can be installed outside the first inner core 21.

[0042] The first inner core 21 is made of plastic material, and the second inner core 22 is made of aluminum alloy material, that is, the outside and inside of the core body 2 are made of different materials, among which the plastic material can be selected from nylon material. Nylon material has strong toughness and light weight, and the structural strength of aluminum alloy material is higher than that of plastic material. The second inner core 22 inside the core body 2 is made of aluminum alloy material to improve the strength inside the core body 2, which can improve the connection strength between the core body 2 and other structural parts.

[0043] Therefore, the composite structure made of plastic material and aluminum alloy material can reduce the weight of the core 2. Compared with the core 2 structure made of pure aluminum alloy material, it can reduce the vibration frequency of the bushing structure 100 and improve the overall structural mode.

[0044] In some embodiments, the first inner core 21 and the second inner core 22 are both configured as hollow structures and are formed with weight-reducing holes 23. Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the interior of the first inner core 21 and the second inner core 22 are both constructed as a hollow structure, which includes weight-reducing holes 23 and connecting ribs. The multiple weight-reducing holes 23 can effectively reduce the weight of the first inner core 21 and the second inner core 22 to achieve a lightweight effect, and the multiple connecting ribs can ensure the structural strength of the first inner core 21 and the second inner core 22, and the hollow structure has a simple shape and a neat appearance.

[0045] In some embodiments, the core body 2 is provided with a connecting hole 24 that penetrates axially, and the core body 2 is axially connected to the suspension bracket 5 through a connecting piece 25 that passes through the connecting hole 24. In this way, the connecting hole 24 is passed through the connecting piece 25, so that the core body 2 and the suspension bracket 5 are axially installed.

[0046] Specifically, Figure 1 and Figure 2 As shown, a connecting hole 24 is provided in the middle of the core body 2, and the connecting hole 24 can be constructed as a through hole, and the connecting hole 24 is arranged to penetrate along the axial direction of the core body 2, wherein the connecting member 25 can be a connecting bolt. During installation, the connecting bolt is passed through the connecting hole 24 and threadedly connected to the threaded hole on the suspension bracket 5, thereby realizing a detachable connection between the core body 2 and the suspension bracket 5.

[0047] Among them, an anti-rotation part is provided at the end of the core body 2, and the anti-rotation part is used to position and cooperate with the suspension bracket 5 to limit the relative rotation of the core body 2 and the suspension bracket 5. Therefore, the anti-rotation part can realize the positioning and cooperation of the end of the core body 2 and the suspension bracket 5 to avoid relative rotation between the two.

[0048] In actual design, an anti-rotation part is provided at the end of the core body 2, and a positioning part is provided at one end of the suspension bracket 5 close to the core body 2. The anti-rotation part and the positioning part are positioned and matched, so that the core body 2 and the suspension bracket 5 can be positioned and matched. Therefore, when the bushing structure 100 and the suspension bracket 5 are installed, the anti-rotation part is positioned and matched with the suspension bracket 5, and then the connecting member 25 is passed through the connecting hole 24 and is threadedly connected to the suspension bracket 5. During the tightening process of the connecting bolt, when the tightening torque is large, the friction force increases. Through the positioning and matching of the anti-rotation part and the suspension bracket 5, the second inner core 22 can be prevented from rotating together with the connecting bolt, thereby preventing the main spring 3 from twisting and deforming, and improving the service life of the main spring 3.

[0049] In some embodiments, one of the ends of the anti-rotation part and the suspension bracket 5 is provided with an anti-rotation boss 26 and the other is provided with an anti-rotation groove 51, and the anti-rotation boss 26 and the anti-rotation groove 51 are axially plugged and positioned with the core body 2. That is to say, the anti-rotation boss 26 may be provided at the anti-rotation part, and the anti-rotation groove 51 may be provided at the end of the suspension bracket 5, or the anti-rotation groove 51 may be provided at the anti-rotation part, and the anti-rotation boss 26 may be provided at the end of the suspension bracket 5. Both of these settings can achieve axial plug-in positioning of the anti-rotation boss 26 and the anti-rotation groove 51, and the setting method is simple and flexible.

[0050] Specifically, Figure 1 and Figure 3 As shown, in the present embodiment, the anti-rotation portion can be constructed as an anti-rotation boss 26, which protrudes at the end of the core body 2, and an anti-rotation groove 51 is provided at the end of the suspension bracket 5, and the groove depth of the anti-rotation groove 51 is greater than the protruding height of the anti-rotation boss 26, and the anti-rotation groove 51 is arranged corresponding to the anti-rotation boss 26. During installation, the core body 2 is installed axially with the suspension bracket 5, and when the anti-rotation boss 26 is inserted into the anti-rotation groove 51, the anti-rotation boss 26 and the anti-rotation groove 51 can be plugged and positioned, and the axial positioning installation of the core body 2 and the suspension bracket 5 can be realized. The plug-in positioning installation method has reliable positioning, effectively avoids relative rotation between the suspension bracket 5 and the core body 2, and is simple and convenient to install, and has a simple structure and low processing cost.

[0051] In some embodiments, there are multiple anti-rotation bosses 26, and the multiple anti-rotation bosses 26 are distributed at intervals along the circumference of the core body 2. The suspension bracket 5 is provided with multiple anti-rotation grooves 51, and the multiple anti-rotation grooves 51 are distributed one-to-one with the multiple anti-rotation bosses 26. In this way, the core body 2 and the suspension bracket 5 can be effectively prevented from circumferentially rotating relative to each other through the positioning and insertion of the multiple anti-rotation bosses 26 and the multiple anti-rotation grooves 51.

[0052] Specifically, there are multiple anti-rotation bosses 26, and the multiple anti-rotation bosses 26 are distributed along the circumference of the core body 2 at intervals, and the spacing between adjacent anti-rotation bosses 26 may be the same or different. In the present embodiment, the spacing between adjacent anti-rotation bosses 26 is set to be the same, and correspondingly, there are multiple anti-rotation grooves 51, and the multiple anti-rotation grooves 51 are distributed along the circumference of the suspension bracket 5 at intervals, and the multiple anti-rotation grooves 51 are arranged in a one-to-one correspondence with the multiple anti-rotation bosses 26. During installation, multiple groups of plug-in positioning can be formed on the circumference of the core body 2 and the suspension bracket 5, and when the connecting piece 25 passes through the core body 2 and the suspension bracket 5 is threadedly fastened, the connecting piece 25 can be effectively prevented from driving the core body 2 to rotate relative to the suspension bracket 5, so that the installation of the bushing structure 100 is easier, and the installation process avoids twisting and deformation of the main spring 3, thereby improving the installation accuracy of the bushing structure 100.

[0053] Alternatively, the anti-rotation bosses 26 and the anti-rotation grooves 51 are provided in two groups and matched one by one, and the two groups of anti-rotation bosses 26 are symmetrically distributed on both sides of the connecting hole 24, such as Figure 3 As shown, there are two groups of anti-rotation bosses 26 and anti-rotation grooves 51, and the two groups of anti-rotation bosses 26 and the two groups of anti-rotation grooves 51 are arranged one by one. During installation, two groups of plug-in positioning can be formed in the circumferential direction of the core body 2 and the suspension bracket 5 to ensure reliable circumferential positioning of the two. When the core body 2 is subjected to a rotational torque, the circumferential positioning is relied on to prevent the rotation of the core body 2 from driving the main spring 3 to rotate and affecting the characteristics of the main spring 3. The number of anti-rotation bosses 26 and anti-rotation grooves 51 can be set according to actual needs, and is not limited to the description in this embodiment.

[0054] In some embodiments, the anti-rotation part and the snap-in groove 211 are both located at the same end of the core body 2. In actual design, the anti-rotation part and the snap-in groove 211 can be both located at the same side of the core body 2, wherein the anti-rotation part is located at the end of the core body 2, and the snap-in groove 211 is located at the outer periphery of the core body 2. In this way, during processing, the snap-in groove 211 and the anti-rotation part can be processed simultaneously on the same side of the core body 2, thereby improving processing efficiency. When the vehicle is running or assembled, the anti-collision member 4 can reduce the collision of the structure on one side of the suspension bracket 5 with the outer tube 1. At the same time, locating the anti-rotation part and the snap-in groove 211 at the same end of the core body 2 can facilitate rapid identification of the installation direction of the bushing structure 100 and the suspension bracket 5.

[0055] In some embodiments, the snap-fit ​​groove 211 is configured as an annular groove, and the snap-fit ​​groove 211 is extended along the circumference of the core body 2 , and the inner peripheral edge of the anti-collision component 4 is snap-fitted into the snap-fit ​​groove 211 .

[0056] Specifically, Figure 2 , Figure 3 As shown, the snap-in groove 211 is constructed as an annular groove, which extends along the circumference of the core body 2. The groove width of the annular groove along the axial direction of the core body 2 is greater than or equal to the thickness of the anti-collision member 4. The outer diameter of the anti-collision member 4 is greater than the outer diameter of the outer tube 1 to prevent the outer tube 1 from collision. The inner diameter of the anti-collision member 4 is greater than or equal to the inner diameter of the snap-in groove 211, and the inner diameter of the anti-collision member 4 is smaller than the outer diameter of the core body 2. During installation, the anti-collision member 4 is interference installed from the end of the core body 2, and when the inner peripheral edge of the anti-collision member 4 is snapped into the snap-in groove 211, the snap-in installation of the anti-collision member 4 and the snap-in groove 211 can be achieved, and when the inner peripheral edge of the anti-collision member 4 is snapped into the snap-in groove 211, it is ensured that the anti-collision member 4 is firmly snapped along the axial direction of the core body 2.

[0057] In some embodiments, the main spring 3 is made of rubber material, which is elastic and strong. When the bushing structure 100 is subjected to force, the main spring 3 is buffered by elasticity to ensure the stability of the connection between the bushing structure 100 and other structural parts.

[0058] The main spring 3 is constructed to be symmetrical along the first direction and asymmetrical along the second direction, and the first direction is perpendicular to the second direction. Specifically, a mounting cavity is formed inside the main spring 3, and the main spring 3 is sleeved outside the core body 2 through the mounting cavity. The first direction may be a horizontal direction, and the horizontal direction may include a front-back or left-right direction. The second direction may be a vertical direction. The internal structure of the main spring 3 is symmetrical along the horizontal direction and asymmetrical along the vertical direction. Figure 4 As shown, a limiting portion and a buffer space are provided in the main spring 3. The limiting portion is provided in the vertical direction in the main spring 3, and the two limiting portions in the vertical direction are asymmetric structures. The limiting portion can be compressed when subjected to force to achieve a buffering effect, and different high-frequency dynamic stiffnesses can be achieved according to different force differences in the upper and lower directions. Therefore, setting the vertical direction in the main spring 3 as an asymmetric structure can reduce the limitation of the suspension structure, thereby increasing the adjustable space of the suspension stiffness, and its use effect is good and its applicability is strong.

[0059] Furthermore, the internal structure of the main spring 3 is not limited to the above. According to the differences in suspension force, NVH performance and performance requirements of the whole vehicle during vehicle acceleration conditions, the arrangement direction of the asymmetric main spring 3 structure can be flexibly arranged to match the appropriate stiffness and improve the NVH performance of the whole vehicle. In addition, the rubber stiffness can be flexibly adjusted and matched according to the NVH performance and requirements of the actual vehicle to improve the NVH performance of the whole vehicle.

[0060] The utility model also provides a vehicle.

[0061] According to the vehicle of the embodiment of the utility model, a bushing structure 100 of any one of the above-mentioned embodiments is provided. By arranging a snap-in groove 211 on the core body 2 to snap-fit ​​with the anti-collision component 4, the anti-collision component 4 can be axially limited. The installation is reliable and can avoid falling off during transportation or vehicle assembly. The installation method is simple, which reduces the difficulty of assembly and thus reduces labor costs.
