The aforementioned solution solves the problem in the prior art that noise reduction from the design and manufacturing of the range extender itself requires the use of advanced technologies and materials, which increases production costs.

[0020] In this embodiment, the fixing ring 102 is fixedly connected to the outer wall of the range extender body 101, and the range extender body 101 is located inside the fixing ring 102. The cylinder 106 is slidably connected to the range extender body 101, and the range extender body 101 is located inside the cylinder 106. The mounting ring 105 is fixedly connected to the cylinder 106 and located above the cylinder 106. A plurality of telescopic components are disposed between the mounting ring 105 and the fixing ring 102. The mounting frame 107 is slidably connected to the cylinder 106 and located above the cylinder 106. A plurality of pressure components are disposed between the mounting frame 107 and the cylinder 106. When the range extender body 101 is working, the range extender body... Vibration will occur in the range extender body 101. The impact force generated by the vibration of the range extender body 101 can be decomposed into vertical force and horizontal force. When the range extender body 101 vibrates, it slides inside the cylinder 106. Multiple telescopic components simultaneously and rapidly extend and retract. At the same time, the range extender body 101 and the cylinder 106 slide irregularly inside the mounting frame 107. Multiple pressure components rapidly extend or retract. The extension and retraction of multiple telescopic components and multiple pressure components absorb the kinetic energy generated by the vibration of the range extender body 101, thereby reducing the vibration of the range extender body 101 and effectively reducing the noise of the range extender body 101. The structure and components of this device are simple, thus reducing the production cost of the device.

[0021] Furthermore, the two ends of the damping rod 104 are fixedly connected to the fixing ring 102 and the mounting ring 105 respectively, the two ends of the telescopic spring 103 are fixedly connected to the fixing ring 102 and the mounting ring 105 respectively, and the damping rod 104 is located inside the telescopic spring 103.

[0022] Furthermore, the first mounting plate 112 is fixedly connected to the mounting frame 107, the second mounting plate 114 is fixedly connected to the cylinder 106, and the two ends of the reset spring 113 are fixedly connected to the first mounting plate 112 and the second mounting plate 114 respectively.

[0023] In this embodiment, when the range extender body 101 is working, the range extender body 101 will vibrate. The impact force generated by the vibration of the range extender body 101 can be decomposed into vertical force and horizontal force. When the range extender body 101 vibrates, the range extender body 101 slides inside the cylinder 106. The multiple telescopic springs 103 and the multiple damping rods 104 simultaneously and rapidly extend and retract. At the same time, the range extender body 101 and the cylinder 106 slide irregularly inside the mounting frame 107. The multiple return springs 113 rapidly extend or retract. The extension and retraction of the multiple telescopic springs 103 and the multiple return springs 113 absorb the kinetic energy generated by the vibration of the range extender body 101, thereby reducing the vibration of the range extender body 101 and effectively reducing the noise of the range extender body 101. The structure and components of this device are simple, thereby reducing the production cost of the device.

[0024] Furthermore, the sound insulation layer 111 is fixedly connected to the protective cover 110 and is located inside the protective cover 110. The protective cover 110 is detachably connected to the mounting frame 107 through the connecting kit, and the range extender body 101 is located inside the protective cover 110.

[0026] In this embodiment, when the range extender body 101 is working, the protective cover 110 encloses the range extender body 101, and the sound insulation layer 111 absorbs the noise emitted by the range extender body 101, further eliminating the noise emitted by the range extender body 101. At the same time, the installation and removal of the protective cover 110 are carried out through the internal threaded cylinder 108 and the external threaded cylinder 109. The installation and removal of the protective cover 110 and the sound insulation cotton are relatively simple, which improves the structural rationality of the device.

[0027] Using this invention to silence the range extender body 101, when the range extender body 101 is working, the range extender body 101 will vibrate. The impact force generated by the vibration of the range extender body 101 can be decomposed into vertical force and horizontal force. When the range extender body 101 vibrates, the range extender body 101 slides within the cylinder 106, and the multiple telescopic springs 103 and the multiple damping rods 104 simultaneously and rapidly extend and retract. At the same time, the range extender body 101 and the cylinder 106 slide irregularly within the mounting frame 107, and the multiple telescopic springs 103 and the multiple damping rods 104 simultaneously and rapidly extend and retract. The rapid extension or contraction of the position spring 113, along with the extension and contraction of the multiple telescopic springs 103 and the multiple return springs 113, absorbs the kinetic energy generated by the vibration of the range extender body 101, thereby reducing the vibration of the range extender body 101 and effectively reducing the noise of the range extender body 101. At the same time, the protective cover 110 encloses the range extender body 101, and the sound insulation layer 111 absorbs the noise emitted by the range extender body 101, further eliminating the noise emitted by the range extender body 101. The structure and components of this device are simple, thereby reducing the production cost of the device.
