Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a simple and convenient automotive exhaust pipe kit structure. Background Technology

[0002] To facilitate the disassembly and replacement of exhaust pipes, automotive exhaust pipes typically require a set of restraining structures. Existing set restraining structures are mostly ring-shaped. Because the ring-shaped hollow structure cannot be compressed, it takes up a lot of space when stored and is not convenient to carry. Summary of the Invention

[0003] The purpose of this application is to provide a car exhaust pipe kit structure that is smaller in size and more convenient to carry.

[0004] To achieve the above objectives, this application provides a simple and convenient automotive exhaust pipe kit structure: including a flexible sheet, the outer side of which is covered with a chain plate hoop, the two ends of which are constraint members, two of which are adapted to be fixedly connected by a connector, the constraint members are rotatably connected to a wide hoop plate by a long pin, the wide hoop plate is rotatably connected to a narrow hoop plate by a short pin, and the narrow hoop plate is then rotatably connected to another wide hoop plate by another short pin. The narrow and wide hoop plates between the two constraint members are arranged alternately, so that the kit structure has flexible folding characteristics, which can effectively reduce the storage space occupied, thus making it more portable.

[0005] As a preferred embodiment, the constraint member includes an end clamp plate having a semi-circular arc side, a pair of clearance grooves formed on the semi-circular arc side of the end clamp plate, and two parallel planes having indirect shaft holes communicating with the clearance grooves in the planes; the wide clamp plate has two semi-circular arc sides, and a pair of limiting plates on each semi-circular arc side, adapted to be embedded in the clearance grooves, the limiting plates having outer shaft holes, and the long pin being adapted to simultaneously engage with the outer shaft hole and the indirect shaft hole to form a rotating pair capable of large-angle rotation.

[0006] As a preferred embodiment, the narrow hoop has two semi-circular arc sides and two planar sides. The narrow hoop has two inner shaft holes on each planar side, which are respectively close to the semi-circular arc side. The semi-circular arc side of the narrow hoop is located between two limiting plates on the same semi-circular arc side of the wide hoop. The short pin is adapted to simultaneously engage with the inner shaft hole and the outer shaft hole, and is also used to form a rotating pair that can complete the folding action.

[0007] As a preferred embodiment, the end clamp has a connecting plate extending vertically on the side opposite to the semi-circular arc side. The connecting plate extends away from the flexible sheet and has connecting holes for bolts and other connecting components to pass through for fastening.

[0008] As a preferred embodiment, the narrow hoop, wide hoop, and end hoop are all arc-shaped with equal diameters, which can better force the flexible sheet to conform to the cylindrical surface of the exhaust pipe.

[0009] As a preferred embodiment, the flexible sheet is fixedly connected to the inner side of the arc of the narrow hoop, the wide hoop, and the end hoop, for direct soft contact with the exhaust pipe.

[0010] As a preferred embodiment, the two ends of the flexible sheet are fixedly connected to two constraint members respectively, and move closer or further away from the two constraint members in sync.

[0011] As a preferred embodiment, the flexible sheet is made of rubber or silicone material, and the inner wall of the flexible sheet is provided with friction grooves to further improve the contact friction between the flexible sheet and the surface of the exhaust pipe, thereby improving the stability of the kit structure after installation.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing narrow and wide hoop plates that are spaced apart and rotatably connected, the kit structure can be folded flexibly to reduce the space occupied and make it more portable.

[0014] (2) By designing a flexible sheet structure to directly contact the exhaust pipe, the indentation and scratches caused by hard contact are avoided. At the same time, the buffering capacity of the flexible sheet also brings shock absorption and noise reduction effects, which can better extend the service life of the exhaust pipe.

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] like Figure 1-7The simplified and convenient automotive exhaust pipe kit shown includes a flexible sheet 6 made of rubber or silicone material, which directly contacts the outer surface of the exhaust pipe. It has a certain shock absorption and buffering effect, effectively avoiding wear and indentation caused by hard contact friction, and reducing noise generation. The flexible sheet 6 has a uniform width and thickness, and can form a ring to wrap around the outside of the exhaust pipe. The inner wall of the flexible sheet 6 has friction grooves 601 to enhance the friction between the flexible sheet 6 and the outer surface of the exhaust pipe, further reducing the possibility of relative movement, thereby improving the constraint stability of the kit on the exhaust pipe.

[0028] The flexible sheet 6 is covered with a rigid, deformable chain plate hoop 7, which is usually made of corrosion-resistant alloy material. The two ends of the chain plate hoop 7 are constraint members 5. The two constraint members 5 can be fixed together by bolts or other connecting parts. The constraint members 5 are rotatably connected to the wide hoop plate 2 through the long pin shaft 4. Specifically, the constraint member 5 includes an end hoop plate 501. The end hoop plate 501 has a semi-circular arc side. The end hoop plate 501 has a pair of relief grooves 503 on the semi-circular arc side. The end hoop plate 501 also has two parallel planes. The end hoop plate 501 has an indirect shaft hole 504 in the plane that connects to the relief grooves 503.

[0029] On the other hand, the wide hoop 2 has two semi-circular arc sides. The wide hoop 2 has a pair of limiting plates 201 on each semi-circular arc side, which are embedded in the relief groove 503. The limiting plate 201 has an outer shaft hole 202. The long pin 4 will be inserted and engaged with the outer shaft hole 202 and the indirect shaft hole 504 at the same time, thereby forming a rotating pair.

[0030] The wide hoop 2 is rotatably connected to the narrow hoop 1 via a short pin 3. The narrow hoop 1 has two semi-circular arc sides and two planar sides. On each planar side of the narrow hoop 1, there are two inner shaft holes 101, one near the semi-circular arc side. The semi-circular arc side of the narrow hoop 1 is located between two limiting plates 201 on the same semi-circular arc side of the wide hoop 2. The side of the limiting plate 201 facing away from the narrow hoop 1 is flush with the planar side of the wide hoop 2. The short pin 3 is used to simultaneously engage with both the inner shaft hole 101 and the outer shaft hole 202. The narrow hoop 1 is then rotatably connected to another wide hoop 2 via another short pin 3. In fact, the narrow hoop 1 and wide hoop 2 between the two constraint members 5 must be arranged alternately to achieve a continuous connection.

[0031] Narrow hoop 1, wide hoop 2 and end hoop 501 are arcs of equal diameter. Flexible piece 6 is fixedly connected to the inner side of the arc of narrow hoop 1, wide hoop 2 and end hoop 501. In this way, chain plate hoop 7 can better constrain flexible piece 6 to make it fit tightly against the outer side of exhaust pipe. The two ends of flexible piece 6 are fixedly connected to two constraint members 5 respectively. Therefore, flexible piece 6 will move closer or further away from the two constraint members 5 in sync.

[0032] The end clamp 501 has a connecting plate 502 extending vertically on the other side away from the semi-circular arc side. The connecting plate 502 has a connecting hole 505. The connecting holes 505 on the two connecting plates 502 are aligned, allowing bolts and other connecting parts to pass through for fastening. The connecting plate 502 extends away from the flexible sheet 6. The outwardly extending connecting plate 502 not only avoids contact with the exhaust pipe, but also facilitates the disassembly and assembly of the connecting parts.

[0033] Working principle: When not in use, this kit is foldable and occupies very little space, making it highly portable. To use, unfold the kit, align the flexible sheet 6 with the outer surface of the exhaust pipe, and wrap it around the outside of the suspended exhaust pipe until the connecting plates 502 of the two constraint members 5 are close together. At this point, the flexible sheet 6 is tightly wrapped around the outside of the exhaust pipe. Then, align the connecting hole 505 of the connecting plate 502 with the through hole on the frame, and tighten it with bolts and nuts. Once secured, the exhaust pipe will remain stable relative to the frame. Disassembly is also convenient; simply loosen the bolts, and the entire kit will detach from the exhaust pipe under its own weight. It can also be folded back into a flat shape that occupies very little space and stored in the storage box for future use.

[0034] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
