Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle exhaust system suspension structures, and more specifically, relates to a suspension structure and a vehicle. Background Art

[0002] Automobile exhaust systems generally use rubber hangers to connect the exhaust system to the vehicle body frame. While bearing the gravity of the exhaust system, the rubber hangers also have the functions of limiting, cushioning, and absorbing the vibration of the exhaust system, which can effectively improve the comfort of passengers when riding.

[0003] Currently, there are two main types of exhaust rubber hangers: 1. A double-hole hanger consisting solely of a rubber hanger block. During installation, the hooks on both ends of the vehicle body and exhaust side are connected through the same rubber hanger; 2. A metal frame is vulcanized around the rubber hanger block. The metal frame is bolted to the vehicle body or frame, and the exhaust side hook is inserted into the rubber hanger block mounting hole in the middle of the metal frame. Both of these rubber hangers have shortcomings: 1. The double-hole hanger can rotate around the hook, resulting in insufficient positional restraint; 2. After the metal frame is vulcanized around the rubber hanger, the metal frame's positional restraint prevents the hook from being inserted into the hanger, causing the rubber hanger to be overly constrained. This significantly reduces the rubber hanger's ability to cushion and absorb exhaust system vibrations. Therefore, neither of these two structures can achieve a good hanging effect.

[0027] Please also refer to Figures 1 to 6 The suspension structure and vehicle provided by the present invention are now described. The suspension structure includes a mounting base 1, a main suspension hook 2, an auxiliary suspension hook 3, and a flexible suspension base 4. The mounting base 1 is connected to the vehicle frame. The main suspension hook 2 and the auxiliary suspension hook 3 are both connected to the same side of the mounting base 1 and are arranged adjacent to each other. The flexible suspension base 4 is suspended from the main suspension hook 2. The lower portion of the main suspension hook 2 is provided with a mounting hole 41 for mounting the exhaust side suspension hook.

[0028] When the flexible hanger 4 is in a swinging state, the peripheral wall of the auxiliary hook 3 can abut against the side edge of the flexible hanger 4 to limit the swing amplitude of the flexible hanger 4 .

[0029] Compared with the prior art, the hanging structure provided in this embodiment has a flexible hanger 4 hung on the main hook 2 on the mounting base 1, and the mounting hole 41 on the flexible hanger 4 is used to install the exhaust side hook. During driving, the exhaust system and the flexible hanger 4 swing synchronously, and the swing amplitude of the flexible hanger 4 is limited by the auxiliary hook 3 on the side of the main hook 2, so that the swing amplitude of the flexible hanger 4 is within a certain range. The above structure can not only limit the installation of the exhaust system to a certain extent, but also effectively absorb the vibration of the exhaust system.

[0030] In this embodiment, the exhaust hook is typically mounted on the muffler or catalyst of the exhaust system, and the exhaust system is connected to the mounting hole 41 of the flexible hanger 4 via the exhaust hook. The exhaust system generates vibrations during exhaust, which are effectively absorbed by the flexible hanger 4, preventing them from being transmitted to the vehicle frame and affecting the passenger experience.

[0031] During driving, the flexible hanger 4 swings vertically around the main hook 2 due to road bumps, and the auxiliary hook 3 can abut against the side edge of the flexible hanger 4, so that the swing amplitude of the flexible hanger 4 is constrained by the auxiliary hook 3, so that the flexible hanger 4 is stably in a certain swing amplitude, realizing effective limitation of the exhaust system, avoiding the problem of excessive constraint on the exhaust system, and solving the problem of insufficient limitation on it.

[0032] Specifically, the flexible hanger 4 is made of flexible materials such as rubber and silicone, and the upper part of the flexible hanger 4 is provided with a hanging hole 45 connected to the main hook 2. The main force-bearing position of the hanging hole 45 is the upper part of the hole wall, and the main force-bearing position of the mounting hole 41 is the lower part of the hole wall. Since the flexible hanger 4 is made of flexible material, it has a certain amount of deformation. In order to avoid the hanging hole 45 and the mounting hole 41 being deformed by force and causing the hole diameter to become larger, a pressing half ring 46 is provided on the lower hole wall of the hanging hole 45 and the upper hole wall of the mounting hole 41 respectively. The pressing half ring 46 extends along the circumference of the hole shape and can press against the lower part of the main hook 2 or the upper part of the exhaust side hook, ensuring that the flexible hanger 4 can be stably hung on the main hook 2, and at the same time ensuring that the exhaust side hook is stably hung on the flexible hanger 4.

[0033] During driving, the flexible hanger 4 swings vertically around the center axis of the hanging hole 45. When the flexible hanger 4 contacts the auxiliary hook 3, it forms a good buffering effect by its own flexibility, avoiding damage to the exhaust system caused by the rigid collision between the two, which helps to extend the service life of the component.

[0034] The flexible hanger 4 can be in various shapes such as rectangular, polygonal, elliptical, and long strips, and can form a flexible limit through the side edge and the auxiliary hook 3 to effectively limit the swing amplitude, so that the installation of the exhaust system can be limited while avoiding excessive constraints.

[0035] In some embodiments, the above-mentioned flexible hanger 4 can be used as follows Figures 5 and 6 The structure shown. Figure 2 The flexible hanger 4 is a quadrilateral component, the long sides of the flexible hanger 4 are arranged in the up and down directions, and the middle part of the flexible hanger 4 is arc-shaped and convex outward.

[0036] In this embodiment, the flexible hanger 4 is a quadrilateral member. When the flexible hanger 4 is at rest, its long sides are arranged in the vertical direction, and its short sides are arranged in the horizontal direction. In the vertical direction, the width of the middle portion of the flexible hanger 4 is greater than that of the ends, facilitating contact and limiting contact with the auxiliary hook 3 at the side edges, thereby achieving effective limiting action.

[0037] In some possible implementations, the above-mentioned flexible hanger 4 adopts the following Figures 5 and 6 The structure shown. Figures 5 and 6The flexible hanger 4 is provided with a deformation hole 42 extending in the up-down direction. The width of the middle portion of the deformation hole 42 is greater than the widths of the upper and lower ends of the deformation hole 42 .

[0038] In this embodiment, on the basis of utilizing its own flexible material to achieve deformation, a deformation hole 42 is also provided on the flexible hanger 4. When the side edge of the flexible hanger 4 abuts against the auxiliary hook 3, the compression deformation of the deformation hole 42 can achieve a buffering effect, thereby avoiding rigid collision between structures.

[0039] At the same time, the outwardly curved protrusion in the middle of the flexible hanger 4 also facilitates the positioning of the deformation hole 42. The width of the middle portion of the deformation hole 42 is greater than the width of the upper and lower ends, which facilitates the deformation performance of the deformation hole 42. When the flexible hanger 4 abuts the auxiliary hook 3, the deformation hole 42 is structurally squeezed, and the width of the middle portion of the deformation hole 42 becomes smaller. The deformation of the deformation hole 42 absorbs the impact energy between the flexible hanger 4 and the auxiliary hook 3, thereby enhancing the cushioning effect, avoiding both structural damage and noise generation.

[0040] In some embodiments, the above-mentioned characteristic deformation hole 42 can be formed as follows: Figures 5 and 6 The structure shown. Figure 2 There are two deformation holes 42 , and the two deformation holes 42 are respectively arranged close to the two side edges of the flexible hanger 4 .

[0041] In this embodiment, two deformation holes 42 are provided and symmetrically located on both sides of the flexible hanger 4, which can achieve a double energy absorption effect, enhance the deformation ability of the flexible hanger 4 when colliding with the auxiliary hook 3, and improve the buffering and vibration reduction performance of the flexible hanger 4.

[0042] In some embodiments, see Figure 5 and Figure 6 The flexible hanger 4 is also provided with a tensioning hole 43, which is connected between the two deformation holes 42 and located between the main hook 2 and the exhaust pipe hook. The two ends of the tensioning hole 43 are connected to the two deformation holes 42 in a one-to-one correspondence.

[0043] In this embodiment, the two ends of the tensioning hole 43 are connected to the middle positions of the two deformation holes 42 one by one, and the tensioning hole 43 is located between the lifting hole 45 and the mounting hole 41, that is, between the lifting hole 45 and the mounting hole 41, that is, located in the middle position of the flexible hanger 4.

[0044] Under the action of its own gravity, the exhaust system exerts a downward pulling force on the flexible hanger 4. At this time, the tensioning hole 43 can be tensioned and opened downward, so that the flexible hanger 4 forms a tension deformation in the up and down directions at the position of the tensioning hole 43. The tensioning hole 43 is used to transmit the above-mentioned action to the deformation hole 42, so that multiple points of the flexible hanger 4 are evenly stressed, avoiding damage caused by excessive local force at the installation hole 41.

[0045] In some embodiments, see Figure 5 and Figure 6 The side of the flexible hanger 4 is provided with a matching notch 44, which can abut against the peripheral wall of the auxiliary hook 3 to limit the swing amplitude of the flexible hanger 4.

[0046] In this embodiment, the mating notch 44 on the side edge of the flexible hanger 4 flexibly abuts against the auxiliary hook 3, creating surface contact between the peripheral wall of the auxiliary hook 3 and the inner wall of the mating notch 44. This interaction limits the swing amplitude of the flexible hanger 4 (and also limits the swing amplitude of the exhaust system). The provision of the mating notch 44 helps increase the contact area with the auxiliary hook 3, preventing damage caused by the auxiliary hook 3's long-term impact on a specific point of the flexible hanger 4, thereby extending the service life of the flexible hanger 4.

[0047] For some possible implementations, see Figure 4 The above-mentioned main hook 2 and auxiliary hook 3 both adopt similar structures. The main hook 2 and auxiliary hook 3 both include a connecting rod 31 and a hook rod 32. The connecting rod 31 is connected to the side of the mounting seat 1 and extends obliquely downward. The hook rod 32 is connected to the lower end of the connecting rod 31 and extends to a side away from the mounting seat 1. The flexible hanging seat 4 is hung on the hook rod 32 of the main hook 2.

[0048] In this embodiment, the connecting rod 31 of the main hook 2 extends in the up and down directions, and is connected to the mounting seat 1 by means of the connecting rod 31. The hook rod 32 at the lower end of the connecting rod 31 is used to form a lifting effect on the flexible suspension seat 4. The hook rod 32 of the auxiliary hook 3 can form a pressing effect with the side edge of the flexible suspension seat 4 or the matching notch 44 of the flexible suspension seat 4 to meet the buffering and vibration absorption performance.

[0049] Furthermore, the connecting rod 31 of the auxiliary hook 3 is inclined from top to bottom toward the side away from the main hook 2, so that there is a certain inclination angle between the connecting rod 31 and the longitudinal plane, which increases the connection length between the connecting rod 31 and the mounting seat 1 to a certain extent, and improves the reliability of the structural connection. The connecting rod 31 of the main hook 2 and the connecting rod 31 of the auxiliary hook 3 are arranged parallel to each other, satisfying the limiting effect of the auxiliary hook 3 on the swing amplitude of the flexible suspension seat 4.

[0050] In some embodiments, see Figure 4 The outer end of the hook rod 32 of the main hook 2 is provided with a limiting end head 21, which is used to limit the axial position of the flexible hanger 4 on the hook rod 32. The limiting end head 21 at the outer end of the hook rod 32 is detachably connected to the hook rod 32. After the flexible hanger 4 is installed, the limiting end head 21 is installed to the outer end of the hook rod 32 to limit the axial position of the flexible hanger 4, ensuring the reliability of the installation and preventing it from falling off the hook rod 32.

[0051] In some possible implementations, the above-mentioned characteristic mounting seat 1 is used as follows Figure 4 The structure shown. Figure 4 The mounting seat 1 is a strip-shaped plate-like component, and the middle part of the mounting seat 1 has a connecting portion 11 protruding toward the side away from the frame. The main hook 2 and the auxiliary hook 3 are both connected to the outer side wall of the connecting portion 11.

[0052] In this embodiment, the connecting portion 11 provided on the mounting seat 1 is provided to protrude toward the outside of the vehicle body, and a cavity that passes through from top to bottom is formed between the back side of the connecting portion 11 and the side wall of the frame. The setting of the connecting portion 11 effectively enhances the structure of the mounting seat 1 itself, meets the hanging installation requirements of the exhaust system, and improves the stability of the installation of components such as the main hook 2, the auxiliary hook 3, the flexible hanger 4 and the exhaust system.

[0053] Specifically, both sides of the connecting portion 11 are connected to the mounting seat 1 through a transition surface 12. An obtuse angle is formed between the transition surface 12 and the plate surface of the mounting seat 1. On the one hand, it facilitates the structural forming of the connecting portion 11. On the other hand, it can form a structural support effect on both sides of the connecting portion 11, thereby improving the overall strength of the structure.

[0054] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, comprising a suspension structure. The vehicle utilizes a main suspension hook 2 to suspend a flexible suspension seat 4, wherein a mounting hole 41 on the flexible suspension seat 4 is provided for mounting an exhaust-side suspension hook. During driving, the exhaust system and the flexible suspension seat 4 swing synchronously, and the swing amplitude of the flexible suspension seat 4 is limited by the auxiliary suspension hook 3, so that the swing amplitude of the flexible suspension seat 4 is within a certain range, thereby avoiding both excessive and insufficient restraint on the exhaust system.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
