Description

Technical Field

[0001] The invention relates to a 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 logistics device for a dual exhaust pipe muffler 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

[0032] 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.

[0033] 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.

[0034] like Figure 7 , 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. As can be seen from the figure, compared with the muffler body and the exhaust pipe, the air duct 61 is slightly upturned, and its end is significantly deflected to the left. If it is improperly fixed to cause suspension or extrusion, it is easy to cause the connection between the air duct 61 and the exhaust pipe, and the connection between the exhaust pipe and the muffler body to break under stress or vibration. In addition, the double exhaust pipe muffler 6 has a large lateral dimension, a non-compact structure, and occupies a large lateral space, which is not conducive to centralized packaging of multiple double exhaust pipe mufflers 6 .

[0035] In view of the above structural features of the dual exhaust pipe muffler 6, a specific embodiment of the present invention provides a logistics apparatus for the dual exhaust pipe muffler, which is composed of a plurality of apparatus bodies distributed longitudinally, and the top surface 3 of the apparatus body is recessed inward to form two cavities that are staggered and distributed oppositely and adapted to the bottom structure of the dual exhaust pipe muffler 6, and each cavity can accommodate a dual exhaust pipe muffler 6 deflected in a horizontal posture, that is, the dual exhaust pipe muffler 6 is placed in the cavity in a horizontal posture with the bottom downward, and its horizontal position is rotated around the longitudinal axis by a certain angle, corresponding to the deflection angle of the air duct 61. The cavity plays a role of lateral limit for the dual exhaust pipe muffler 6.

[0036] like Figures 1 to 6 As shown, they are respectively the top stereogram, bottom stereogram, top view, front view, left view and bottom view of the apparatus body in the embodiment of the present invention. As can be seen from the figure, the apparatus body is composed of a first apparatus split body 1 and a second apparatus split body 2 which are distributed in the left and right directions, separated from each other and have the same structure, that is, a split design is adopted, and the above-mentioned two cavities are both arranged on the first apparatus split body 1 and the second apparatus split body 2. The first apparatus split body 1 and the second apparatus split body 2 are both made of expanded polystyrene (EPS), which is a light polymer polymer. It is made of polystyrene resin with a foaming agent added, and heated to soften, and gas is generated to form a rigid closed-cell foam plastic with low water absorption, good heat preservation, light weight and high mechanical strength. The significance of adopting a split design for the apparatus body is that, first, the middle section is omitted, which is conducive to weight reduction and material saving; second, it is conducive to reducing the structural size, which is convenient for production and transportation; third, the two apparatus split bodies can be used in common, reducing the mold opening cost.

[0037] The tool body composed of the first tool body 1 and the second tool body 2 is regarded as a whole, the top surface 3 of the tool body is recessed inward to form a support surface 4, two cavities are formed on the support surface 4, and the bottom surface 5 of the tool body is protruded outward to form a support boss 51 adapted to the support surface 4, that is, the protrusion height of the support boss 51 compared to the bottom surface 5 of the tool body is the same as the recessed depth of the support surface 4 compared to the top surface 3 of the tool body, and the contour shape of the support boss 51 is the same as the contour shape of the top surface 3 of the tool body, both of which are annular square frame structures. When several tool bodies are stacked, the support boss 51 of the upper tool body is embedded in the support surface 4 of the lower tool body, and the bottom surface 5 of the upper tool body is pressed against the top surface 3 of the lower tool body, so as to realize the lateral limitation of the two adjacent tool bodies. At the same time, the supporting boss 51 of the upper device body serves as a longitudinal limit for the dual exhaust pipe muffler 6 accommodated in the lower device body, thereby firmly fixing the dual exhaust pipe muffler 6 in the cavity.

[0038] The cavities on the first instrument body 1 and the second instrument body 2 specifically include: a left muffler body cavity 41, a right muffler body cavity 42, a right exhaust pipe groove 44, a left exhaust pipe groove 43, and an air duct groove 45, which are sequentially distributed and connected along the front-to-back direction. Among them, the left muffler body cavity 41 is adapted to the bottom surface structure of the left muffler body 621 and the left exhaust port 622 of the dual exhaust pipe muffler 6, the right muffler body cavity 42 is adapted to the bottom surface structure of the right muffler body 631, the right exhaust pipe groove 44 is adapted to the bottom surface structure of the right exhaust pipe 63, the left exhaust pipe groove 43 is adapted to the bottom surface structure of the left exhaust port 622 near the connection between it and the air duct 61, and the air duct groove 45 is adapted to the bottom surface structure of the air duct 61, so as to fix the corresponding parts on the dual exhaust pipe muffler 6. The mold cavity on the first device body 1 and the second device body 2 also includes a mounting hook groove 46 connected to the right exhaust pipe 63, which is adapted to the mounting hook 64 of the dual exhaust pipe muffler 6 to accommodate it in an airtight manner to avoid damage caused by pressure. The above mold cavity design is based on the end of the air duct 61 deflecting to the left. If the end of the air duct 61 deflects to the right, it can be slightly modified based on the technical solution, and the modified technical solution still does not exceed the protection scope of the present invention.

[0039] The first tool body 1 and the second tool body 2 are each provided with two grooves 47 formed by the top surface being recessed inwards, which are beneficial to saving materials and reducing weight, and secondly, can accommodate spare parts and tools of the dual exhaust pipe muffler 6. Figure 3 It can be seen that the four grooves 47 are centrally symmetrically distributed in the horizontal direction to avoid the center of gravity shifting.

[0040] The edge of the bottom surface 5 of the main body is inwardly recessed to form a first lateral groove 53 and a second lateral groove 54. There are no less than two first lateral grooves 53 and second lateral grooves 54 and they are symmetrically distributed. The recess depth of the first lateral groove 53 is greater than the recess depth of the second lateral groove 54. The significance of this design is that the operator can put his hand into the first lateral groove 53 and the second lateral groove 54, so as to facilitate the lifting of the device body containing the dual exhaust pipe muffler 6. The first lateral groove 53 has a large recess depth, which is convenient for the operator to grasp but has poor load-bearing capacity; the second lateral groove 54 has a small recess depth and a strong load-bearing capacity but is not convenient for the operator to grasp. The operator can flexibly determine the grasping position according to the situation.

[0041] The support boss 51 and the cavity surface of the cavity are provided with a shock absorbing groove 48 which is indented inwards. The significance lies in that if the longitudinal acceleration is generated by bumps or collisions during transportation and loading and unloading, the device body is squeezed to produce longitudinal deformation and expand outward in the lateral direction, providing space for the longitudinal deformation, thereby improving the shock absorbing performance.

[0042] The supporting boss 51 of the device body is recessed inwards, forming a plurality of adapting grooves adapted to the top structure of the dual exhaust pipe muffler 6, each adapting groove is distributed on the first device body 1 and the second device body 2, specifically including: a left muffler body adapting groove 521, a right muffler body adapting groove 522, a right exhaust pipe adapting groove 523, and an air duct adapting groove 524, which are sequentially distributed along the front-to-back direction. Among them, the left muffler body adapting groove 521 is adapted to the top surface structure of the left muffler body 621, the right muffler body adapting groove 522 is adapted to the top surface structure of the right muffler body 631, the right exhaust pipe adapting groove 523 is adapted to the top surface structure of the middle section of the right exhaust pipe 63, and the air duct adapting groove 524 is adapted to the top surface structure of the end of the air duct 61.

[0043] The significance of designing the above-mentioned adapter grooves is that in order to stack more device bodies in a limited carrying space and accommodate more dual exhaust pipe silencers 6, the height of each layer of device bodies must be strictly limited. Due to the large longitudinal dimensions, the top surface structures of the left muffler body 621 and the right muffler body 631 may extend upward beyond the support surface 4, and the excess portion is accommodated by the left muffler body adapter groove 521 and the right muffler body adapter groove 522 of the upper device body. The right exhaust pipe 63 has an upward curvature, and the portion of its middle section that extends beyond the support surface 4 is accommodated by the right exhaust pipe adapter groove 523 of the upper device body. The portion of the end of the air duct 61 that is upwardly bent and extends beyond the support surface 4 is accommodated by the air duct adapter groove 524 of the upper device body. Through the design of each adapter groove, the dual exhaust pipe silencer 6 can be prevented from being squeezed and damaged while limiting the height of each layer of the device body. Specifically, Figures 8 to 10 Shown are a top perspective view, a top view, and a front view of the device body accommodating a dual exhaust pipe muffler.

[0044] 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.
