However, this method requires the use of many nuts for installation, resulting in low installation efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a noise reduction component and a muffler that are easy to install and have high installation efficiency.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A noise reduction assembly includes an outer frame and a noise reduction chamber, the noise reduction chamber being housed within the outer frame. The assembly further includes two elastic members and at least two connecting members. The two elastic members are disposed opposite to each other on the two side walls of the noise reduction chamber, and the noise reduction chamber is clamped between two opposite inner walls of the outer frame by the two elastic members. The two connecting members are disposed opposite to each other on the two end walls of the noise reduction chamber, and each connecting member is rotatably connected to the noise reduction chamber. The rotation axis of each connecting member is the same as the length direction of the noise reduction chamber.

[0006] The connector is configured to at least partially protrude from the sidewall of the muffler and hook onto the outer frame, and to be recessed into the sidewall of the muffler when rotated relative to the endwall of the muffler.

[0008] The hook portion is configured to at least partially protrude from the side wall of the muffler and hook onto the outer frame, and to be recessed into the side wall of the muffler when rotated relative to the end wall of the muffler.

[0009] In one embodiment, the outer frame is provided with a clearance area, and the clearance area is provided with a hook rod, which is connected to the outer frame;

[0010] The hook part is positioned to avoid the outer frame through the avoidance area, and when the hook part protrudes from the side wall of the muffler, the hook part is located in the avoidance area and abuts against the side of the hook rod away from the muffler.

[0011] In one embodiment, the rotating part and the hooking part are integrally formed.

[0012] In one embodiment, the rotating part is rotatably connected to the end wall of the muffler via a rotating shaft.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] The silencing assembly of this utility model has two elastic members disposed opposite to each other on the two side walls of the silencing chamber. This allows the silencing chamber to be clamped between the two opposite inner walls of the outer frame by the two elastic members, achieving vertical positioning and fixation of the silencing chamber. In conjunction, two connecting members are disposed opposite to each other on the two end walls of the silencing chamber. The connecting members are rotatably connected to the silencing chamber. The connecting members are configured to at least partially protrude from the side walls of the silencing chamber and hook onto the outer frame, and to be recessed into the side walls of the silencing chamber when rotating relative to the end walls of the silencing chamber. This ensures that when the connecting members rotate relative to the silencing chamber, a portion of the connecting member can protrude. The outer side of the muffler's peripheral wall can be retracted to the inner side of the muffler's peripheral wall. This allows the muffler to be clamped between the two opposing inner walls of the outer frame by two elastic members when the connector is retracted to the inner side of the muffler's peripheral wall. After the muffler is housed in the outer frame, the connector can be rotated so that part of the connector extends out of the outer side of the muffler's peripheral wall and hooks into the outer frame. In other words, the horizontal positioning and fixing of the muffler is achieved through the two connectors, effectively ensuring the effective positioning and fixing of the muffler within the outer frame. Furthermore, the installation operation is simple, effectively improving the installation efficiency of the muffler within the outer frame. Attached Figure Description

[0028] This application provides a noise reduction assembly. The noise reduction assembly includes an outer frame, a noise reduction chamber, two elastic members, and at least two connecting members. The noise reduction chamber is housed within the outer frame. The two elastic members are disposed opposite each other on the side walls of the noise reduction chamber, and the noise reduction chamber is clamped between opposite inner walls of the outer frame by the two elastic members. The two connecting members are disposed opposite each other on the end walls of the noise reduction chamber, and each connecting member is rotatably connected to the noise reduction chamber, with the axis of rotation of each connecting member being the same as the length direction of the noise reduction chamber. The connecting members are configured to at least partially protrude from the side walls of the noise reduction chamber and hook onto the outer frame, and to be recessed into the side walls of the noise reduction chamber when rotating relative to the end walls of the noise reduction chamber.

[0029] The aforementioned silencing assembly arranges two elastic members opposite to each other on the side walls of the silencing chamber, thereby clamping the silencing chamber between the two opposing inner walls of the outer frame via the two elastic members, achieving vertical positioning and fixation of the silencing chamber. Simultaneously, two connecting members are arranged opposite to each other on the end walls of the silencing chamber, rotatably connected to the silencing chamber. The connecting members are configured to at least partially protrude from the side walls of the silencing chamber and hook onto the outer frame, and when rotating relative to the end walls of the silencing chamber, they are recessed into the side walls of the silencing chamber, ensuring that a portion of the connecting member extends outwards when rotating relative to the silencing chamber. The outer side of the silencing shell's peripheral wall can be retracted to the inner side of the silencing shell's peripheral wall. This allows the silencing shell to be clamped between the two opposing inner walls of the outer frame by two elastic members when the connecting piece is retracted to the inner side of the silencing shell's peripheral wall. After the silencing shell is housed in the outer frame, the connecting piece can be rotated so that part of the connecting piece extends out of the outer side of the silencing shell's peripheral wall and hooks into the outer frame. In other words, the horizontal positioning and fixing of the silencing shell is achieved through the two connecting pieces, effectively ensuring the effective positioning and fixing of the silencing shell within the outer frame. Furthermore, the installation operation is simple, effectively improving the installation efficiency of the silencing shell within the outer frame.

[0030] To better understand the noise reduction component of this application, the following further explanation is provided:

[0031] Please refer to the following: Figures 1 to 4 One embodiment of the silencing assembly 10 includes an outer frame 100, a silencing chamber 200, two elastic members 300, and at least two connecting members 400. The silencing chamber 200 is housed within the outer frame 100. The two elastic members 300 are disposed opposite to each other on the two side walls of the silencing chamber 200, and the silencing chamber 200 is clamped between two opposite inner walls of the outer frame 100 by the two elastic members 300. The two connecting members 400 are disposed opposite to each other on the two end walls of the silencing chamber 200, and each connecting member 400 is rotatably connected to the silencing chamber 200, with the axis of rotation of each connecting member 400 being in the same direction as the length of the silencing chamber 200. The connecting members 400 are configured to at least partially protrude from the side wall of the silencing chamber 200 and hook onto the outer frame 100, and to be recessed into the side wall of the silencing chamber 200 when rotating relative to the end wall of the silencing chamber 200.

[0032] The aforementioned silencing assembly 10 arranges two elastic members 300 oppositely on the two side walls of the silencing chamber 200, thereby clamping the silencing chamber 200 between the two opposing inner walls of the outer frame 100 via the two elastic members 300, achieving vertical positioning and fixation of the silencing chamber 200. In conjunction, two connecting members 400 are arranged oppositely on the two end walls of the silencing chamber 200, and the connecting members 400 are rotatably connected to the silencing chamber 200. The connecting members 400 are configured to at least partially protrude from the side wall of the silencing chamber 200 and hook onto the outer frame 100, and when rotating relative to the end wall of the silencing chamber 200, they are recessed into the side wall of the silencing chamber 200, ensuring that when the connecting members 400 rotate relative to the silencing chamber 200, a portion of the connecting member 400 can extend out of the silencing chamber. The outer side of the peripheral wall of the silencing duct 200 can be retracted to the inner side of the peripheral wall of the silencing duct 200. This allows the silencing duct 200 to be clamped between the two opposing inner walls of the outer frame 100 by the two elastic members 300 when the connecting member 400 is retracted to the inner side of the peripheral wall of the silencing duct 200. After the silencing duct 200 is housed in the outer frame 100, the connecting member 400 can be rotated so that part of the connecting member 400 extends out of the outer side of the peripheral wall of the silencing duct 200 and hooks with the outer frame 100. In other words, the horizontal limiting and fixing of the silencing duct 200 is achieved through the two connecting members 400, which effectively ensures the effective limiting and fixing of the silencing duct 200 within the outer frame 100. Moreover, the installation operation is simple, which effectively improves the installation efficiency of the silencing duct 200 within the outer frame 100.

[0033] Please refer to the following: Figures 1 to 4In one embodiment, each connector 400 includes a rotating portion 410 and a hooking portion 420. The hooking portion 420 is located on the outer periphery of the rotating portion 410 and connected to the rotating portion 410. The rotating portion 410 is rotatably connected to the end wall of the muffler 200, and the rotation axis of the rotating portion 410 is in the same direction as the length of the muffler 200. Further, the hooking portion 420 is configured to at least partially protrude from the side wall of the muffler 200 and hook onto the outer frame 100, and to be recessed into the side wall of the muffler 200 when rotating relative to the end wall of the muffler 200. This better ensures effective rotation between the connector 400 and the end wall of the muffler 200, and better ensures effective hooking between the connector 400 and the outer frame 100.

[0034] Please refer to the following: Figures 1 to 4 In one embodiment, the outer frame 100 is provided with a clearance area 101, and a hook rod 500 is provided on the clearance area 101, which is connected to the outer frame 100. Further, the hook part 420 is clearance-set with the outer frame 100 through the clearance area 101, and when the hook part 420 partially protrudes from the side wall of the muffler 200, the hook part 420 is located at the clearance area 101 and abuts against the side of the hook rod 500 away from the muffler 200, effectively ensuring the stable connection of the connector 400 to the outer frame 100, and better ensuring the effective horizontal limiting and fixing of the muffler 200.

[0035] Please refer to the following: Figures 1 to 4 In one embodiment, the rotating part 410 and the hook part 420 are integrally formed, which improves the connection stability and compactness of the rotating part 410 and the hook part 420, thereby improving the structural strength and compactness of the connector 400, and reducing the processing steps of the connector 400, thereby improving the processing and manufacturing efficiency of the noise reduction assembly 10.

[0036] Please refer to the following: Figures 1 to 4 In one embodiment, the rotating part 410 is rotatably connected to the end wall of the muffler 200 via the rotating shaft 700, which better ensures the rotational stability of the rotating part 410 on the end wall of the muffler 200.

[0037] In one embodiment, the elastic element is a vulcanized rubber elastic element, an EPDM rubber elastic element, a fluororubber elastic element, or a silicone rubber elastic element, which ensures that the elastic element has good weather resistance and corrosion resistance, and also ensures that the elastic element has good elasticity, thereby ensuring the vertical positioning and fixing stability of the muffler and facilitating the smooth connection to the outer frame.

[0038] Please refer to the following: Figures 1 to 4In one embodiment, the silencing chamber 200 is provided with a microporous silencing plate 600. The microporous silencing plate 600 is connected to the side wall of the silencing chamber 200 to form a silencing cavity (not shown). The microporous silencing plate 600 and each elastic element 300 are respectively located on opposite side walls of the silencing chamber 200, which better ensures the silencing effect of the silencing chamber 200.

[0039] In one embodiment, the silencing cavity is filled with a silencing filler, which further ensures the silencing effect of the silencing chamber.

[0040] In one embodiment, the sound-absorbing body is a glass fiber sound-absorbing filler or a rock wool sound-absorbing filler, which further ensures the sound-absorbing effect of the sound-absorbing chamber.
