Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1 to 3, the vehicle according to an embodiment of the present invention includes a beam assembly 1, the beam assembly 1 includes a resonance component 10, a beam 20, and an interior trim 30, the resonance component 10 is disposed on the beam 20 and located between the beam 20 and the interior trim 30. The resonant assembly 10 is capable of effective vibration absorption. In the present embodiment, the cross member 20 is a front top cross member of a vehicle. In other embodiments, the cross member 20 may be other components of the vehicle that require shock absorption, such as a rear top cross member, a front windshield cross member, a rear windshield cross member, and the like.

Referring to fig. 1, 4 and 5, in an embodiment, the resonant assembly 10 includes a resonant body 100, an elastic bushing 200 and a connecting unit 300, wherein the resonant body 100 is provided with a mounting hole 110; the elastic bushing 200 is disposed in the mounting hole 110; the connecting unit 300 includes a connecting member 310 and a first supporting member 320, one end of the connecting member 310 passes through the elastic bushing 200 and is connected to the first supporting member 320, a first buffering member 400 is disposed between the first supporting member 320 and the resonant body 100, a second buffering member 500 is disposed on one side of the resonant body 100 opposite to the first buffering member 400, and the other end of the connecting member 310 is configured to be mounted on the cross beam 20.

Since the other end of the connecting member 310 is mounted on the cross beam 20 and one end is connected to the first supporting member 320, the resonant body 100 is effectively located between the cross beam 20 and the first supporting member 320, which facilitates the resonant body 100 to achieve the purpose of dynamic vibration absorption through the elastic bushing 200. And because the first bolster 400 is arranged on one side of the resonance body 100 facing the first supporting piece 320, and the second bolster 500 is arranged on one side facing the cross beam 20, the vibration displacement of the resonance body 100 is effectively reduced by using the first bolster 400 and the second bolster 500, abnormal sound generated by collision and impact of the resonance body 100 and the cross beam 20 or the interior trim 30 and the like is reduced, and the driving experience is effectively improved.

In an embodiment, as shown in fig. 10 to 14, the first buffer 400 is disposed on the first supporting member 320, and a gap is formed between the first buffer 400 and the resonant body 100. Specifically, the gap is 0.5mm to 1.5mm. By having a gap between the first buffer 400 and the resonant body 100, the buffering effect can be further improved, and the vibration amplitude of the resonant body 100 is limited. In the present embodiment, the gap between the first bumper 400 and the resonant body 100 is a gap in the axial direction of the mounting hole 110.

In another embodiment, as shown in fig. 15 to 18, the first buffer 400 is disposed on the resonant body 100, and a gap is formed between the first buffer 400 and the first supporting member 320. Specifically, the gap is 0.5mm to 1.5mm. By forming a gap between the first buffer member 400 and the first supporting member 320, that is, by forming a gap between the first supporting member 320 and the resonant body 100, the buffering effect can be further improved, and the vibration amplitude of the resonant body 100 can be limited. In this embodiment, the gap between the first cushion member 400 and the first supporting member 320 is a gap in the axial direction of the mounting hole 110.

Referring to fig. 2 and 4, in an embodiment, an avoiding groove 130 is further formed on a side of the resonant body 100 facing the first supporting element 320, the first buffer 400 is located in the avoiding groove 130, and a gap is formed between the first buffer 400 and a sidewall of the avoiding groove 130. It can be understood that the first cushion member 400 has a gap with the sidewall of the escape groove 130 in the radial direction of the mounting hole 110, and thus the cushion effect of the resonance body 100 in the radial direction can be achieved by the first cushion member 400.

In one embodiment, as shown in fig. 10, 11, 13, 15 and 16, the second buffer 500 is disposed on the resonant body 100, and a gap can be formed between the second buffer 500 and the beam 20. Specifically, the gap is 0.5mm to 1.5mm. The gap can be formed between the second buffer member 500 and the cross beam 20, that is, the gap can be formed between the resonant body 100 and the cross beam 20, so that the buffering effect is further improved, and the vibration amplitude of the resonant body 100 is limited.

In another embodiment, as shown in fig. 12, 14, 17, 18, a gap is provided between the second buffer 500 and the resonant body 100. Specifically, the gap is 0.5mm to 1.5mm. Further improving the damping effect on the resonant body 100 and limiting the vibration amplitude of the resonant body 100.

The gap is small in size, so that the buffering effect on the resonance body 100 can be further improved by using the small gap, excessive vibration of the resonance body 100 is prevented, the vibration amplitude of the resonance body 100 is limited, and the durability of the resonance assembly 10 can be further improved. If there is no gap, on one hand, the buffering effect on the resonant body 100 is affected, and on the other hand, the first buffer 400 or the second buffer 500 participates in energy absorption, which affects the vibration absorption frequency of the resonant body 100.

Referring to fig. 1, 4 and 5, in the present embodiment, the resonant body 100 is mounted on the top beam, and a gap formed between the resonant body 100 and the beam 20 through the first buffer 400 is smaller than a gap formed between the resonant body 100 and the first supporting member 320 through the second buffer 500. Specifically, for example, since the resonant body 100 is mounted on the top beam 20, and thus the gap formed between the resonant body 100 and the beam 20 through the first bumper 400 is 0.7mm, the gap formed between the resonant body 100 and the first supporting member 320 through the second bumper 500 is 1.3mm. Due to the self-weight of the resonator body 100, the resonator body 100 sinks relative to the cross beam 20, so that the upper gap and the lower gap of the resonator body 100 are both about 1 mm.

In one embodiment, the other end of the connecting member 310 is mounted on the beam 20, the resonant body 100 is located between the beam 20 and the interior trim component 30, and the resonant body 100 is spaced apart from the beam 20 and the interior trim component 30. Specifically, the distance between the resonant body 100 and the beam 20 is 3mm to 6mm; the distance between the resonator body 100 and the trim piece 30 is 4mm-8mm. By providing the resonant body 100, the cross beam 20, and the upholstery 30 with gaps, it is possible to further prevent the resonant body 100 from colliding with the cross beam 20 or the upholstery 30 to generate abnormal noise, and also prevent the cross beam 20 and the upholstery 30 from affecting the vibration absorption frequency of the resonant body 100.

In the present embodiment, the distance between the resonant body 100 and the beam 20 is about 4 mm; the distance between the resonator body 100 and the trim piece 30 is 5mm or more.

Referring to fig. 6 and 7, in one embodiment, the size of the first buffer 400 tends to decrease in a direction toward the gap between the first supporting element 320 and the resonant body 100. For example, as shown in fig. 10 to 14, the first buffer 400 is disposed on the first supporting member 320, and the size of the first buffer 400 in the direction toward the resonant body 100 tends to decrease. As shown in fig. 15 to 18, if the first buffer 400 is disposed on the resonant body 100, the size of the first buffer 400 in the direction toward the first supporting member 320 tends to decrease. Taking the first buffering member 400 disposed on the first supporting member 320 as an example, since the size of the first buffering member 400 tends to be reduced, when the first buffering member 400 contacts the resonant body 100, the first buffering member 400 can limit the resonant body 100, and meanwhile, the contact area between the first buffering member 400 and the resonant body 100 is small, so that the influence of the first buffering member 400 on the inherent frequency modulation of the resonant body 100 can be further reduced. If the contact area between the first buffer 400 and the resonant body 100 is large, the intrinsic frequency modulation of the resonant body 100 is inevitably affected.

In this embodiment, the first buffer 400 has a trapezoidal structure, and the size of the first buffer 400 gradually decreases toward the adjacent gap. In other embodiments, the first buffer 400 may also be a conical structure, or may also be a semi-spherical structure, as long as the gap between the first buffer 400 and the resonant body 100 or the first supporting member 320 can be reduced.

In one embodiment, there are at least two first buffers 400, and each first buffer 400 is spaced around the axis of the mounting hole 110. The buffering effect on the resonance body 100 can be ensured by providing at least two first buffers 400. Specifically, the number of the first buffers 400 is plural, and the plurality of first buffers 400 are uniformly spaced around the axis of the mounting hole 110.

In another embodiment, the first buffer 400 has an annular structure, and the mounting hole 110 is aligned with an inner annular space of the first buffer 400. The first cushion member 400 having an annular shape can further improve the cushion effect on the resonance body 100. Specifically, the surface of the first buffer 400 facing the gap may be a plane, a cambered or wavy surface, a saw-toothed surface, or the like.

In an embodiment, as shown in fig. 10 to 14, if there is a gap between the first buffer 400 and the resonant body 100, the first supporting member 320 is wrapped with a third buffer 322, and the first buffer 400 is integrally formed on the third buffer 322. Specifically, as shown in fig. 2 and 4, the first buffer 400 and the third buffer 322 are integrally formed and then wrapped on the outer edge of the third buffer 322, and a gap is formed between the first buffer and the inner wall of the avoiding groove 130 of the resonant body 100.

In this embodiment, the third cushion member 322 is directly molded on the first supporting member 320, so that the stability of the third cushion member 322 disposed on the first supporting member 320 can be improved, and the stability of the first cushion member 400 disposed on the first supporting member 320 can be further improved.

Specifically, the third buffer 322 and the first buffer 400 are integrated, and the third buffer 322 may be made of rubber. Further, the rubber may be natural rubber NR, EPDM, silicone rubber VMQ, or the like. The third buffer 322 and the first buffer 400 made of rubber can not only realize the buffering effect on the resonant body 100, but also change the natural frequency of the resonant body 100 by adjusting the damping and hardness of the rubber and changing the effective mass of the resonant assembly 10. In addition, the anti-aging performance of the rubber can be improved by adjusting the tensile strength and the tearing strength of the rubber, so that the rubber has no crack, no crack and no falling after being subjected to road spectrum test under the conditions of high temperature and low temperature.

In another embodiment, as shown in fig. 15 to 18, if there is a gap between the first buffering member 400 and the first supporting member 320, the first buffering member 400 is integrally formed on a side of the elastic sleeve 200 facing the first supporting member 320. The first cushion member 400 is integrally formed with the elastic bush 200, so that the reliability of the first cushion member 400 provided to the elastic bush 200 can be improved, and the reliability of the gap formed between the first cushion member 400 and the first receiving member 320 can be improved.

Referring to fig. 1, 5 to 6, in one embodiment, the connection unit 300 further includes a locking member 330, the locking member 330 is disposed on the first supporting member 320, and one end of the connection member 310 is connected to the locking member 330. The coupling stability of the coupling member 310 can be improved by providing the locker 330.

Specifically, the first supporting member 320 is provided with a first connection hole 324, the locking member 330 abuts against a side of the first supporting member 320 opposite to the first buffer member 400 and is aligned with the first connection hole 324, and one end of the connection member 310 passes through the first connection hole 324 to be connected with the locking member 330. Further, the connecting member 310 is a bolt, the locking member 330 is a nut, and the threaded section of the bolt passes through the first connecting hole 324 to be in locking connection with the nut.

In this embodiment, the locking member 330 may be integrally formed on the first supporting member 320, for example, the locking member 330 may be welded on the first supporting member 320, or the locking member 330 may be pressed and riveted on the first supporting member 320, so as to prevent the locking member 330 from falling off relative to the first supporting member 320. Of course, the locking member 330 can also abut against the first support member 320 only by means of the connecting member 310.

Referring to fig. 1, 5, 8 and 9, in one embodiment, the size of the second buffer 500 tends to decrease in a direction toward the gap between the beam 20 and the resonant body 100. For example, the second damper 500 is disposed on the resonant body 100, the size of the second damper 500 in a direction away from the resonant body 100 tends to decrease. If there is a gap between the second buffer 500 and the resonant body 100, the size of the second buffer 500 in the direction of the resonant body 100 tends to decrease. When the second cushion member 500 performs the cushioning function by the abutment, the abutment area of the second cushion member 500 can be small, and the influence of the second cushion member 500 on the natural frequency modulation of the resonance body 100 can be further reduced. If the contact area of the second cushion member 500 is large, the intrinsic frequency modulation of the resonance body 100 is inevitably affected.

In one embodiment, there are at least two second buffering members 500, and each of the second buffering members 500 is spaced around the axis of the mounting hole 110. The provision of at least two second dampers 500 ensures an effective damping action for the resonant body 100. Specifically, the number of the second buffers 500 is plural, and the plural second buffers 500 are arranged at regular intervals around the axis of the mounting hole 110.

In another embodiment, the second buffer 500 has a ring-shaped structure, and the mounting hole 110 is aligned with an inner ring space of the second buffer 500. The damping effect on the resonant body 100 can be further improved by the annular second damper 500. Specifically, the surface of the second buffer 500 facing the gap may be a flat surface, a cambered or wavy surface, a sawtooth surface, or the like.

In one embodiment, as shown in fig. 10, 11, 13, 15, and 16, if the second cushion 500 can form a gap with the cross beam 20, the second cushion 500 is integrally molded with the elastic bushing 200. The second cushion 500 is integrally formed with the elastic bush 200, so that the stability of the installation of the second cushion 500 can be improved.

Specifically, as shown in fig. 11, 13, and 16, the radial width of the second buffer 500 is greater than or equal to the radial wall thickness of the elastic bush 200, and the outer edge of the second buffer 500 is located outside the outer wall of the elastic bush 200. If the radial width of the second cushion 500 is small, on one hand, the abutting stability during the buffering process is affected, and on the other hand, the second cushion 500 is turned outwards relative to the elastic bushing 200, which affects the usability of the second cushion 500. In this embodiment, as shown in fig. 11, 13 and 16, the outer edge of the second dampener 500 can extend outwardly of the mounting hole 110 to prevent eversion of the second dampener 500 relative to the elastomeric bushing 200.

In an embodiment, the elastic bushing 200 and the second buffer member 500 are integrated, and the elastic bushing 200 may be made of rubber, and the elastic bushing 200 and the second buffer member 500 made of rubber not only can achieve a buffering effect on the resonant body 100, but also can further change the natural frequency of the resonant body 100 by adjusting the damping and hardness of the rubber and changing the effective mass of the resonant assembly 10. In addition, the anti-durability performance of the rubber can be improved by adjusting the tensile strength and the tearing strength of the rubber, so that the rubber has no crack, no crack and no falling off after being subjected to road spectrum test under the conditions of high temperature and low temperature.

In another embodiment, as shown in fig. 12, 14, 17 and 18, the connection unit 300 further includes a second supporting element 340, the second supporting element 340 is disposed on a side of the resonant body 100 opposite to the first supporting element 320, and the second buffering element 500 is disposed on the second supporting element 340, so that a gap is formed between the second buffering element 500 and the resonant body 100. When in use, the second supporting member 340 can abut against the beam 20, and the second buffering member 500 is disposed on the second supporting member 340, so that a gap between the second buffering member 500 and the resonant body 100 is formed.

Referring to fig. 4 and 5 again, in the present embodiment, the outer edge of the first supporting member 320 has a size larger than the diameter of the mounting hole 110. If the elastic bushing 200 fails due to a special abnormal condition, and the elastic bushing 200 and the resonant body 100 may fall downward, since the outer edge of the first supporting member 320 is larger than the aperture of the mounting hole 110, the fallen elastic bushing 200 and the resonant body 100 may fall on the first supporting member 320, and the first supporting member 320 may play a role of falling-off failure protection for the elastic bushing 200 and the resonant body 100, so as to prevent the resonant body 100 and the elastic bushing 200 from directly falling onto the interior trim 300, which may cause a safety problem.

In one embodiment, the resonant assembly 10 further includes an inner supporting sleeve 600 and an outer supporting sleeve 700, the elastic bushing 200 is sleeved outside the inner supporting sleeve 600, the outer supporting sleeve 700 is sleeved outside the elastic bushing 200, the outer supporting sleeve 700 is inserted into the mounting hole 110, the connecting member 310 is inserted into the inner supporting sleeve 600, and one end of the inner supporting sleeve 600 abuts against the first supporting member 320. When the device is mounted, as shown in fig. 1, the other end of the inner support sleeve 600 can abut against the cross member 20. The elastic bush 200 can be effectively supported by providing the inner support sleeve 600 and the outer support sleeve 700.

In one embodiment, the outer diameter of the first support member 320 is larger than the outer diameter of the outer support sleeve 700. Specifically, the inner diameter of the first connection hole 324 of the first susceptor 320 is less than or equal to the inner diameter of the inner support sleeve 600. The inner support sleeve 600 and the outer support sleeve 700 can be further supported by the first support member 320.

Referring to fig. 11, 13 and 16, in an embodiment, a supporting flange 710 is formed on an outer edge of a side of the outer supporting sleeve 700 facing away from the first supporting member 320, and the second buffering member 500 is integrally formed on the elastic bushing 200 and can abut against the supporting flange 710. The utilization supports turn-ups 710 can effectively bearing second bolster 500, improves the stability that second bolster 500 set up.

Referring to fig. 2 and 3, in an embodiment, the number of the mounting holes 110 is two, all the mounting holes 110 are spaced apart, and the center of mass of the resonant body 100 is located on a line connecting the axes of the two mounting holes 110. In particular, the centre of mass of the resonator body 100 is equidistant from the axes of the two mounting holes 110. If the center of mass of the resonator body 100 cannot be located on the line connecting the axes of the two mounting holes 110, or if there are more connecting lines deviating from the axes of the two mounting holes 110, the mass on both sides of the connecting line connecting the axes of the two mounting holes 110 may be unequal, which may cause one side to bear too much energy-absorbing load, and the other side to be too small, which may cause frequency modulation failure, and may also easily cause the durable failure of the elastic bushing 200.

In other embodiments, the number of mounting holes 110 may be other numbers, and the center of mass of the resonant body 100 is located at the intersection of the lines connecting the axes of the respective mounting holes 110. Or the center of mass of the resonator body 100 is disposed equidistant from the axial center of each mounting hole 110.

In the present embodiment, the resonant body 100 may be made of ductile iron, gray cast iron, cast steel, zinc alloy, or low carbon steel.

Referring to fig. 1 to 3, in an embodiment, an avoidance space 120 is formed on an outer wall of the resonant body 100. By forming the avoidance space 120 in the resonance body 100, a gap can be effectively formed between the resonance body 100 and the cross beam 20 and the upholstery 30, and the resonance body 100 can be further prevented from colliding with the cross beam 20 or the upholstery 30.

Specifically, the depth of the bypass space 120 in the axial direction of the mounting holes 110 gradually increases from the line connecting the axes of the two mounting holes 110 to the outer edge of the resonant body 100. The mass of the resonator body 100 can be maximized by forming the escape space 120 in a slanted manner.

Of course, in other embodiments, the avoidance space 120 may be formed by directly forming a groove on the resonant body 100 at a position to be avoided. In another embodiment, a felt, a rubber pad, or the like may be provided at a position where the escape space 120 cannot be formed for cushioning.

In one embodiment, an avoiding space 120 is also formed on the resonant body 100 on a side of one mounting hole 110 opposite to the other mounting hole 110. Specifically, the depth of the avoiding space 120 gradually increases from the adjacent mounting hole 110 to the outer edge.

In one embodiment, a vehicle includes a beam assembly 1 as in any of the above embodiments.
