Description

Technical Field

[0001] The invention relates to a large-capacity logistics device for a double exhaust pipe muffler, belonging to the technical field of packaging boxes. Background Art

[0002] Today, as the division of labor in the automotive industry develops rapidly, auto parts are usually manufactured by auto parts manufacturers scattered in different regions according to design drawings, and then transported to the assembly department of the auto company for unified assembly. In the process of auto parts leaving the factory, storage, transportation, and assembly, scientific selection of auto parts packaging boxes is conducive to minimizing transportation losses, reducing transportation costs, and improving transportation efficiency.

[0003] Automobile mufflers are used to reduce the exhaust noise of the engine and to discharge high-temperature exhaust gas safely and effectively. The principle is that the automobile exhaust pipe is composed of two pipes of different lengths. The two pipes are separated and then intersected. Since the length difference between the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere with each other when superimposed and weaken the sound intensity, so that the transmitted sound is reduced, thereby achieving the effect of muffler. Automobile mufflers are mainly composed of two sections of exhaust pipes with specific curvatures. Due to their irregular shape, the space utilization rate of the packaging box is low during storage and transportation; due to their long size, the exhaust pipe connection is subject to great stress, and it is easy to cause damage due to transportation bumps or external impacts. At present, when the muffler is stored or transported, it is usually placed in a wooden or paper packaging box, and it is prevented from being damaged by filling it with flexible materials such as sponges and foams. This packaging method not only has the defects of poor shock absorption, loose fixation, and easy pollution, but also makes it difficult to take into account its own strength and weight at the same time. The double exhaust pipe muffler has an air duct and two exhaust pipes, each of which is connected to a muffler body. Due to its large lateral size and non-compact structure, it is further difficult to improve the utilization of packaging space and enhance logistics efficiency. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a large-capacity logistics device for a dual exhaust pipe muffler, so as to solve the technical problems in the prior art of poor shock absorption, loose fixation and low packaging space utilization of the dual exhaust pipe muffler packaging box.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0035] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0036] A specific embodiment of the present invention provides a large-capacity logistics device for a dual exhaust pipe muffler, which is composed of a plurality of longitudinally distributed device bodies. The top surface 3 of the device body is recessed inward to form a cavity that is compatible with the dual exhaust pipe muffler 6, and the dual exhaust pipe muffler 6 is accommodated in the cavity with its bottom facing downward.

[0037] like Figure 7As shown, it is a stereoscopic diagram of a dual exhaust pipe muffler in an embodiment of the present invention. The dual exhaust pipe muffler 6 has an air duct 61 connected to the engine exhaust manifold. The air duct 61 is connected to two exhaust pipes, namely, a left exhaust pipe 62 and a right exhaust pipe 63; the exhaust pipe is provided with a muffler body and an exhaust port, that is, the left exhaust pipe 62 is sequentially connected to the left muffler body 621 and the left exhaust port 622, and the right exhaust pipe 63 is sequentially connected to the right muffler body 631 and the right exhaust port 632. The air duct 61, the exhaust pipe, and the muffler body are also provided with a mounting hook 64 for fixing to the chassis of the automobile. It can be seen from the figure that the dual exhaust pipe muffler 6 has a large lateral dimension, an irregular shape, a non-compact structure, and occupies a large lateral space. The air duct 61 is slightly upturned compared to the muffler body and the exhaust pipe, and it is easy to generate stress when suspended in the air. The connection between the exhaust pipe and the muffler body is prone to breakage under stress or vibration.

[0038] like Figures 1 to 6 As shown, they are respectively a top stereogram, a bottom stereogram, a top view, a front view, a left view, and a bottom view of the device body in the embodiment of the present invention. The device body is composed of a first device body 1 and a second device body 2 that are laterally distributed and separated from each other. The purpose of adopting a split design is not only to save materials and reduce weight, but also to facilitate the production and transportation of the device body. The first device body 1 and the second device body 2 are both made of expanded polystyrene (EPS) by one-piece molding. EPS is a light polymer, which is made of polystyrene resin with a foaming agent added, and heated to soften it to generate gas, forming a rigid closed-cell foam plastic with the characteristics of low water absorption, good thermal insulation, light weight and high mechanical strength.

[0039] The device body composed of the first device body 1 and the second device body 2 is regarded as a whole, and the parts of the cavity that accommodates a dual exhaust pipe muffler 6 are regarded as a cavity. The cavity on the device body can be divided into a first cavity and a second cavity that are distributed in a step-like manner, wherein the cavity surface of the first cavity is lower than the cavity surface of the second cavity. The first cavity and the second cavity both include an air duct groove, an exhaust pipe groove, a muffler body cavity, and an exhaust port groove. The air duct groove, the exhaust pipe groove, the muffler body cavity, and the exhaust port groove are correspondingly arranged on the first device body 1 and the second device body 2, that is, they are arranged on the first device body 1 and the second device body 2 and are cross-distributed.

[0040] The muffler body cavity is matched with the muffler body of the dual exhaust pipe muffler 6, and is used to accommodate the muffler body, and plays a role of lateral limitation and support for it. The air bleed pipe groove is matched with the proximal end of the air bleed pipe 61 of the dual exhaust pipe muffler 6, and is used to accommodate the proximal end of the air bleed pipe 61, and plays a role of lateral limitation and support for it, and eliminates longitudinal stress. The exhaust pipe groove and the exhaust port groove are respectively connected to the muffler body cavity, the exhaust pipe groove is matched with the exhaust pipe on the dual exhaust pipe muffler 6 close to the muffler body, and the exhaust port groove is matched with the exhaust port of the dual exhaust pipe muffler 6, and respectively accommodates the exhaust pipe close to the muffler body and the exhaust port pipe section at the end of the muffler body, which can prevent the exhaust pipe from breaking at the connection between the muffler body and the muffler body under stress or vibration while playing a role of lateral limitation and support.

[0041] More specifically, the first cavity is composed of a first muffler body cavity 31, a first air duct groove 32, a first exhaust port groove 33, and a first exhaust port groove 34. The first muffler body cavity 31 is connected to the first exhaust port groove 33 and the first exhaust port groove 34, respectively. The first air duct groove 32 is at a certain distance from the first muffler body cavity 31. The second cavity is composed of a second muffler body cavity 311, a second air duct groove 321, a second exhaust port groove 331, and a second exhaust port groove 341. The second muffler body cavity 311 is connected to the second exhaust port groove 331 and the second exhaust port groove 341, respectively. The second air duct groove 321 is at a certain distance from the second muffler body cavity 311. Figure 1 and Figure 3 It can be seen that the first cavity and the second cavity are opposite and cross-distributed. Since the cavity surface of the first cavity is lower than the cavity surface of the second cavity, the dual exhaust pipe muffler 6 can be accommodated in a opposite and cross-distributed manner.

[0042] The top surface 3 of the body is concave inward near the first cavity, forming a support surface 4 connected to the first cavity, and the bottom surface 5 of the device body is convex outward, forming a protrusion 51 that matches the support surface 4 and the first cavity, that is, the back of the first cavity and the support surface 4 is formed with a protrusion 51, and this design also corresponds to the lower cavity surface height of the first cavity, that is, the first cavity adopts a sunken design. When two device bodies are stacked, the protrusion 51 of the upper device body is embedded in the first cavity and support surface 4 corresponding to the lower device body. At this time, the protrusion 51 is in contact with the support surface 4, and the bottom surface 5 of the upper device body is in contact with the top surface 3 of the lower device body to ensure balanced load-bearing and stacking stability to avoid overturning. The protrusion 51 of the upper device body and the bottom surface 5 of the body respectively play a role of longitudinal limiting the dual exhaust pipe muffler 6 accommodated in the first cavity and the second cavity of the lower device body, thereby firmly fixing the dual exhaust pipe muffler 6 in the cavity.

[0043] In this embodiment, although the cross-accommodation of two dual exhaust pipe mufflers 6 is achieved by means of the sunken design of the first cavity, due to the longitudinal distribution of the two dual exhaust pipe mufflers 6, in order to stack more device bodies in the same longitudinal space to accommodate more dual exhaust pipe mufflers 6, it is necessary to limit the layer height of the device body. Therefore, it is not ruled out that the dual exhaust pipe mufflers 6 accommodated in the first cavity exceed the height of the support surface 4 upward, and the dual exhaust pipe mufflers 6 accommodated in the second cavity exceed the height of the top surface 3 of the body upward, and thus will be squeezed by the upper device body protrusion 51 and the bottom surface 5 of the body. In response to this problem, the protrusion 51 and the bottom surface 5 of the body are both provided with an air avoidance groove 52 formed by an inward depression to avoid air accommodating the part of the dual exhaust pipe muffler 6 in the lower device body that exceeds the top surface 3 or the support surface 4 of the body, so as to avoid the occurrence of damage caused by squeezing of the dual exhaust pipe muffler 6.

[0044] The edge of the top surface 3 of the main body is inwardly recessed to form a groove 35 communicating with the support surface 4, so that the staff can observe the condition of the dual exhaust pipe muffler 6 accommodated in the device body through the groove 35 and deal with the problem in time if found.

[0045] In this embodiment, the tool body composed of the first tool body 1 and the second tool body 2 is provided with two first cavities and two second cavities. Figure 3 Counting from the back to the front, the 1st and 3rd muffler body cavities are the first muffler body cavities 31, which correspond to the two first cavities, and the air duct 61 of the dual exhaust pipe muffler 6 accommodated in the first cavity faces forward; the 2nd and 4th muffler body cavities are the second muffler body cavities 311, which correspond to the two second cavities, and the air duct 61 of the dual exhaust pipe muffler 6 accommodated in the second cavity faces backward.

[0046] The steps of accommodating the dual exhaust pipe muffler 6 into the apparatus body are as follows: First, the air ducts 61 of the two dual exhaust pipe mufflers 6 are moved forward and accommodated in the two first cavities, as shown in the following example. Figure 8 and Fig. 9 The figures are respectively the top perspective view and the top view of the device body when accommodating two double exhaust pipe mufflers. Then, the air ducts 61 of the other two double exhaust pipe mufflers 6 are moved backwards and accommodated in the two second cavities, as shown in 10 to Fig.13 The figures are respectively a top perspective view, a top view, a front view, and a left view of the apparatus body when accommodating four dual exhaust pipe mufflers. The mounting hooks 64 on the dual exhaust pipe mufflers 6 can be removed and stored centrally, or accommodated in the corresponding avoidance grooves 52 on the protrusions 51 and the bottom surface 5 of the body to avoid damage due to pressure.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
