Description

Technical Field

[0001] This utility model belongs to the field of resonant block technology, and particularly relates to a bidirectional frequency resonant block. Background Technology

[0002] The main purpose of installing resonant blocks (or damping blocks) on the control arms under the vehicle chassis is to suppress vibrations and noise caused by the movement of the suspension and the vehicle body. The function of the resonant blocks is to reduce unnecessary resonance by "tuning" the vibration frequency of the vehicle body structure, thereby improving the comfort and driving quality of the vehicle.

[0003] Conventional resonant blocks can only solve frequency resonance problems in a single direction. They are generally heavy and require more resonant blocks to address vibrations in the Z and Y directions. The multi-unit structural design makes the entire resonant structure complex, with more parts and higher manufacturing costs, resulting in a small contribution to the overall cost of the vehicle. Utility Model Content

[0004] This utility model provides a bidirectional frequency resonant block, which is implemented as follows: A bidirectional frequency resonant block includes:

[0005] The vehicle body connecting frame and the mass block are rectangular parallelepiped structures, and the mass block has a cavity for accommodating the equipment through which the vehicle body connecting frame passes.

[0006] The inner wall of the equipment cavity is provided with a mass block connecting frame. The mass block connecting frame is connected to the vehicle body connecting frame by a rubber component. The rubber component includes an inner ring, an outer ring, and a connecting part connecting the inner ring and the outer ring. There are two sets of connecting parts, which are symmetrically arranged between the inner ring and the outer ring.

[0007] Preferably, the equipment cavity is located at the center of the cuboid mass block, and the equipment cavity is connected to the outside from opposite sides of the mass block, with the mass block extending from one of the vehicle body connecting frames.

[0008] Preferably, the connecting parts are in two sets and are spaced apart between the inner and outer rings. The number of gap areas between the two sets of connecting parts is also two. The gap areas and the connecting parts form a cross structure. By using the stiffness difference between the hollow and solid structures in the cross direction, the resonant frequency ranges during vibration in the Z and Y directions are different, thereby eliminating the resonance in the Z and Y directions generated when the subsystems of the chassis unit are assembled together.

[0009] Preferably, the inner wall of the inner ring is connected to the outer wall of the vehicle body connecting frame, and the outer wall of the outer ring is connected to the inner wall of the mass block connecting frame.

[0010] Preferably, the area occupied by the gap area and the connecting part is one-third of the space between the inner ring and the outer ring.

[0011] Preferably, the axes of the two sets of connecting parts are parallel to the short side of the mass block.

[0012] Preferably, the axes of the two sets of connecting parts are perpendicular to the short side of the mass block.

[0013] Preferably, the center of the vehicle body connecting frame is a hollow structure, and the inner wall of the vehicle body connecting frame is provided with threads for connecting bolts.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages:

[0015] The bidirectional frequency resonant block provided by this utility model has a hollow-solid structure built inside the rubber part through the connecting part. Combined with the cuboid structure design of the mass block, the stiffness in the Z and Y directions is different, so that the resonant frequency ranges during vibration in the Z and Y directions are different. This achieves the matching of frequency resonance pads in the Z and Y directions when the whole vehicle vibrates, eliminates the resonance in the Z and Y directions generated when the subsystems of the chassis unit are assembled together, eliminates noise, reduces the amount of resonant blocks used in the subsystems of the chassis unit, and reduces manufacturing costs.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a bidirectional frequency resonant block, such as Figures 1-4 As shown, the bidirectional frequency resonant block includes:

[0025] The vehicle body connecting frame 1 and the mass block 3 weigh 1 kg. The mass block 3 has a cuboid structure and a device cavity at the center of the mass block 3 to accommodate the vehicle body connecting frame 1. The device cavity is connected to the outside from the opposite side of the mass block 3.

[0026] The inner wall of the equipment cavity is provided with a mass block connecting frame 2. The mass block connecting frame 2 is connected to the vehicle body connecting frame 1 through a rubber component 4. The rubber component 4 includes an inner ring 41, an outer ring 43, and a connecting part 42 connecting the inner ring 41 and the outer ring 43. There are two sets of connecting parts 42, which are symmetrically arranged between the inner ring 41 and the outer ring 43. The equipment cavity, the vehicle body connecting frame 1, the mass block connecting frame 2, and the rubber component 4 are all cylindrical in shape. The vehicle body connecting frame 1, the mass block connecting frame 2, and the rubber component 4 are all made of rubber material, and the three are assembled in the equipment cavity by an interference fit.

[0027] By constructing a hollow-solid structure inside the rubber part 4 through the connecting part 42, and in conjunction with the cuboid structure design of the mass block 3, the stiffness in the Z and Y directions is different, resulting in different frequency ranges of resonance frequency during vibration in the Z and Y directions. This achieves matching of frequency resonance pads in the Z and Y directions when the whole vehicle vibrates, eliminating resonance in the Z and Y directions generated when the subsystems of the chassis unit are assembled together, eliminating noise, reducing the amount of resonant blocks used in the subsystems of the chassis unit, and reducing manufacturing costs.

[0028] The connecting parts 42 here are in two sets and are spaced apart between the inner ring 41 and the outer ring 43. The number of gap regions between the two sets of connecting parts 42 is also two. The gap regions and the connecting parts 42 form a cross structure. Through the stiffness difference between the hollow and solid structures in the cross direction, the resonant frequency ranges of the vibration in the Z and Y directions are different.

[0029] In a preferred embodiment of this invention, the inner wall of the inner ring 41 is connected to the outer wall of the vehicle body connecting frame 1, and the outer wall of the outer ring 43 is connected to the inner wall of the mass block connecting frame 2. The gap area and the connecting part 42 each occupy 1 / 4 of the space between the inner ring 41 and the outer ring 43.

[0030] In this embodiment, the axes of the two sets of connecting parts 42 are parallel to the short side of the mass block 3. Alternatively, the axes of the two sets of connecting parts 42 can be perpendicular to the short side of the mass block 3. The main purpose is to make the axes parallel to one of the side lengths of the cuboid so that the vibration frequency generated can be effectively absorbed by the cuboid.

[0031] In a preferred embodiment of this invention, the center of the vehicle body connecting frame 1 is a hollow structure, and the inner wall of the vehicle body connecting frame 1 is provided with threads for connecting bolts; the vehicle body connecting frame 1 is generally connected to the subframe using a bolt structure.
