Specific implementation mode
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0026] An exhaust pipe for a low-energy consumption vehicle includes a silencer 1, an exhaust pipe main body 2 and a tail pipe 3. The exhaust pipe main body 2 and the tail pipe 3 are respectively communicated with the front side and the rear side of the silencer 1. The surface of the silencer 1 is sleeved with a protection component 4, and the inner walls of the protection component 4 are respectively in contact with the exhaust pipe main body 2 and the tail pipe 3;
[0027] The protection component 4 includes an upper housing 41 and a lower housing 42. The upper housing 41 and the lower housing 42 are respectively located at the top and the bottom of the surface of the silencer 1, and support blocks 43 are arranged on the inner walls of the upper housing 41 and the lower housing 42. The sides of the support blocks 43 close to the surfaces of the silencer 1, the exhaust pipe main body 2 and the tail pipe 3 are respectively in close contact with the silencer 1, the exhaust pipe main body 2 and the tail pipe 3. Frames 44 are arranged on the surfaces of the upper housing 41 and the lower housing 42, and the two frames 44 are bolted together.
[0028] In this embodiment: by setting up the protection component 4, the muffler 1, the exhaust pipe body 2 and the tail pipe 3 can be protected by the upper protective shell 41 and the lower protective shell 42, so that the support block 43 contacts the muffler 1, the exhaust pipe body 2 and the tail pipe 3 respectively to fix the position of the upper protective shell 41 and the lower protective shell 42, and the two frames 44 are connected by adopting a fastening structure, so that the upper protective shell 41 and the lower protective shell 42 can be firmly installed on the muffler 1, the exhaust pipe body 2 and the tail pipe 3, so that the influence of external environmental factors on the automobile exhaust pipe can be isolated, and the exhaust pipe can be prevented from being damaged due to exposure to the environment, resulting in increased energy consumption and power loss of the automobile. By adding a heat-conducting and sound-insulating structure between the protection component 4 and the automobile exhaust pipe, the heat of the exhaust pipe can be guided to the outside air, and at the same time, the transmission of the exhaust pipe noise to the outside is reduced, thereby achieving the effect of further reducing noise.
[0029] Specifically, Figure 5 As shown, the upper protective shell 41 and the lower protective shell 42 both include a main body layer 5, the inner wall of the main body layer 5 is provided with a heat conducting layer 6, and the inner wall of the heat conducting layer 6 is provided with a contact layer 7, a plurality of heat conducting blocks 8 are provided inside the heat conducting layer 6, and the heat conducting blocks 8 are in contact with the main body layer 5 and the contact layer 7 on one side thereof respectively.
[0030] Specifically, Figure 5 As shown, the heat conducting layer 6 is made of aluminum alloy material and is arranged between the main layer 5 and the contact layer 7 .
[0031] Specifically, Figure 5 As shown, the contact layer 7 is made of aluminum foil material, and the side close to the muffler 1, the exhaust pipe body 2 and the tail pipe 3 is in contact with the muffler 1, the exhaust pipe body 2 and the tail pipe 3 respectively.
[0032] In this embodiment: by providing a heat-conducting layer 6 composed of an aluminum alloy material and a contact layer 7 composed of an aluminum foil material, since both the aluminum alloy material and the aluminum foil material have good thermal conductivity, the heat of the exhaust pipe can be quickly conducted out to the environment, and the provision of the heat-conducting block 8 can further accelerate the thermal conductivity efficiency. At the same time, the aluminum foil has sound insulation properties, which can reduce the transmission of exhaust pipe noise to the outside world, thereby achieving the effect of protecting the environment.
[0033] Specifically, Figure 3 As shown, heat dissipation ribs 9 are disposed on the surfaces of the upper protective shell 41 and the lower protective shell 42 , and the heat dissipation ribs 9 are connected to the frame 44 at one side thereof.
[0034] In this embodiment, by providing the heat dissipation ribs 9, on the one hand, the heat dissipation efficiency of the protection component 4 to the exhaust pipe can be accelerated, and on the other hand, the structural strength of the protection component 4 can be enhanced to make it less prone to damage.
[0035] Specifically, Figure 4As shown, a number of fixing cylinders 10 are provided at the top of the top frame 44, and a fastening screw 11 passes through the interior of the fixing cylinder 10. The bottom of the fastening screw 11 passes through the top frame 44 and extends into the interior of the bottom frame 44, and the fastening bolt is threadedly connected to the bottom frame 44.
[0036] Specifically, as Figure 4 shown, a pressure plate 12 and a spring 13 are respectively sleeved on the surface of the fastening screw 11, and one side of the spring 13 close to the top frame 44 and the pressure plate 12 is connected to both of them.
[0037] In this embodiment: Through the above settings, the two frames 44 can be connected by the fastening screw 11, so that the upper housing 41 and the lower housing 42 are firmly installed on the muffler 1, the exhaust pipe main body 2 and the tail pipe 3. Therefore, the influence of external environmental factors on the automobile exhaust pipe can be isolated. By squeezing the spring 13 by the pressure plate 12, the loosening or falling off of the screw due to long-term vibration or oscillation can be prevented, ensuring the firm installation of the protection component 4.
[0038] Specifically, as Figure 4 shown, two sealing protrusions 14 are provided at the bottom of the top frame 44, and the surface of the sealing protrusions 14 is in close contact with the inner wall of the bottom frame 44.
[0039] In this embodiment: By providing the sealing protrusions 14, the sealing performance between the two frames 44 can be increased, effectively improving the protection performance of the protection component 4 for the exhaust pipe.
[0040] Working principle: When the exhaust pipe is in use, the muffler 1, the exhaust pipe main body 2 and the tail pipe 3 can be protected by the upper housing 41 and the lower housing 42, so that the support blocks 43 are in contact with the muffler 1, the exhaust pipe main body 2 and the tail pipe 3 respectively to fix the positions of the upper housing 41 and the lower housing 42. Then, the fastening screw 11 passes through the top frame 44 and is threadedly connected to the bottom frame 44, enabling the connection between the two frames 44, and the upper housing 41 and the lower housing 42 can be firmly installed on the muffler 1, the exhaust pipe main body 2 and the tail pipe 3. Therefore, the influence of external environmental factors on the automobile exhaust pipe can be isolated. When connecting the existing structures such as hooks for installing the exhaust pipe to the protection component 4, the protection component 4 can be connected to the vehicle body by using structures such as hooks. During the exhaust process of the automobile exhaust pipe, the heat of the exhaust pipe can be quickly exported through the heat conduction layer 6, the heat conduction block 8 and the contact layer 7, and guided to the environment through the heat dissipation ribs 9, and the exhaust pipe can be quickly cooled by using the flow of air.
[0041] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
