Detailed Description

FIG. 1 is a schematic diagram of a resonator according to an embodiment of the utility model. Fig. 2 is an enlarged cross-sectional view of a communication tube of the resonator of fig. 1. Fig. 3 is a lower view of an upper portion of a housing of the resonator of fig. 1. Fig. 4 is a top view of a lower portion of the housing of the resonator of fig. 1. In the present embodiment, the resonator 100 is provided in an internal combustion engine system (not shown), for example, and is connected to an air device a including, for example, an air cleaner, an air flow path, a resonance tube, etc. (not shown in detail), but the present utility model is not limited thereto. The resonator 100 may be provided in other structures requiring noise reduction, and is not limited to the internal combustion engine system. The specific structure of the resonator 100 of the present embodiment will be described below with reference to fig. 1 to 4.

Referring to fig. 1 to 4, in the present embodiment, a resonator 100 includes a housing 110 and a communication pipe 120. The housing 110 includes a partition plate S that partitions a space inside the housing 110 into a plurality of resonance chambers R1, R2 (as shown in fig. 3, 4, the present embodiment illustrates only two, but may be more in other not-shown embodiments). The communication pipe 120 is provided in the housing 110 and connected to the air device a. As shown in fig. 2, the partition plate S passes through the communication pipe 120 to partition the communication pipe 120 into a first pipe 122 and a second pipe 124, wherein the first pipe 122 is disposed in the resonance chamber R1, and the second pipe 124 is disposed in the resonance chamber R2. The partition plate S is formed in a shape to cover the portion of the communication pipe 120, and in this embodiment, covers the second pipe 124, for example, but the present utility model is not limited thereto.

As can be seen from this, in the resonator 100 of the present embodiment, the partition plate S divides the communication pipe 120 into two parts, so that one communication pipe 120 has a structure equivalent to two communication pipes 120. Therefore, the space in which other components can be arranged is increased and the assemblability is improved with the downsizing of the communication pipe 120. Further, the provision of the partition plate S also improves the rigidity of the entire resonator 100, and further can reduce noise caused by resonance and improve the durability of the resonator 100. Accordingly, the resonator 100 of the present embodiment has a more compact configuration to improve the assemblability and reduce the resonance noise.

Further, in the present embodiment, the housing 110 is formed of two parts, i.e. the housing 110 includes an upper portion 112 and a lower portion 114, and the communication pipe 120 is, for example, a cylindrical pipe (see fig. 2 and 3) disposed at the upper portion 112 of the housing 110. The partition plate S is divided into a first pipe 122 and a second pipe 124 in a semicircular shape through the center of the communication pipe 120. As shown in fig. 2, the lengths of the first tube 122 and the second tube 124 are formed to be different, e.g., the length of the first tube 122 is greater than the length of the second tube 124. In this way, the resonance frequency can be further adjusted, and the configuration of the first tube 122 and the second tube 124 can also be adjusted to suit different resonance frequencies in cooperation with the length of the resonance tube (not shown) in the air device a. The shape of the communication pipe 120 may be any shape suitable for a pipe, and is not limited to a cylindrical shape; the lengths of the first tube 122 and the second tube 124 may be reversed, and the present utility model is not limited thereto.

Referring to fig. 3 and 4, in the present embodiment, the partition plate S includes a right-angle bending portion L. The right-angle bent portion L is a portion bent in a direction perpendicular to the original extending direction, and is formed at a position outside the communication pipe 120. The right-angle bend L wraps around a portion of the communication tube 120, such as the second tube 124, but may also wrap around the first tube 122 in other embodiments not shown. Therefore, the partition plate S having a bend has higher rigidity than the partition plate S disposed straight, to further reinforce the structure of the communication pipe 120.

In the present embodiment, a seal 116 is formed on a side surface of the case 110 between the upper portion 112 and the lower portion 114. The upper portion 112 and the lower portion 114 are fixed by welding the sealing portion 116 in the up-down direction, but other sealing means may be used, and the present utility model is not limited thereto. The partition plate S is integrally connected to the first surface F1 and the second surface F2 of the case 110, and the first surface F1 does not face the second surface F2. That is, the partition plate S extends in a direction perpendicular to the original extending direction after the right-angle bending, so that the first face F1 and the second face F2 are not in the opposite direction. The partition plate S is integrally provided with the housing 110 to improve rigidity, and is connected to the non-opposing surfaces to further improve rigidity of the membrane surface of the resonator 100, thereby reducing noise caused by resonance. In other embodiments not shown, the separation plate S may be a separate member, and may be fixed to the housing 110 by welding or the like, which is not limited by the present utility model.

As described above, in the resonator of the present utility model, the partition plate divides the communication pipe into two parts, so that one communication pipe has a structure equivalent to two communication pipes. Therefore, the space in which other components can be arranged is increased with the downsizing of the communication pipe, and the assemblability is improved. In addition, the arrangement of the partition plate also improves the rigidity of the whole resonator, so that noise caused by resonance can be reduced, and the durability of the resonator can be improved. And, the division board includes right angle kink, compares with the division board that sets up straight line, has higher rigidity of the division board of buckling to further strengthen the structure of communicating pipe. Accordingly, the resonator of the present embodiment has a more compact configuration to improve the assemblability and reduce the resonance noise.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present utility model.
