[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0031] See the figure below for reference Figure 1-Figure 4 The vibration reduction device 100 according to an embodiment of the present invention is described, and the vibration reduction device 100 can be applied to a vehicle.
[0032] Combination Figure 1-Figure 4As shown, the vibration reduction device 100 according to the embodiment of the utility model can mainly include: a base 10, an adapter block 20 and a vibration reduction assembly 30, wherein the base 10 is used to be connected to the vehicle body, the adapter block 20 is arranged above the base 10 at intervals, and the vibration reduction assembly 30 includes an upper connecting arm 31, a lower connecting arm 32 and a first spring member 33, the lower end of the lower connecting arm 32 is rotatably connected to the base 10, the upper end of the upper connecting arm 31 is connected to the adapter block 20, and the upper connecting arm 31 is sleeved on the circumferential outer side of the lower connecting arm 32. Specifically, the base 10 in the vibration reduction device 100 is connected and fixed to the vehicle body, and the vibration reduction device 100 can be fixed to the vehicle body, and can be used to isolate and eliminate the vibration transmitted to the vehicle body to prevent the vibration from being transmitted to the passenger compartment through the vehicle body frame, so that the comfort in the passenger compartment can be ensured, which is conducive to improving the NVH performance of the vehicle.
[0033] Furthermore, the lower end of the lower connecting arm 32 in the vibration reduction assembly 30 is connected to the base 10, and the upper connecting arm 31 is connected to the adapter block 20. The upper connecting arm 31 is sleeved on the circumferential outer side of the lower connecting arm 32, so that the adapter block 20 can be set in the vibration reduction assembly 30, and the adapter block 20 can maintain a stable position relative to the base 10. The upper end of the lower connecting arm 32 can rotate relative to the base 10, and the upper connecting arm 31 can slide along the axial direction of the lower connecting arm 32 relative to the lower connecting arm 32. When the power in the vehicle is transmitted to the adapter block 20, the shaking of the adapter block 20 can drive the upper connecting arm 31 to move together, and the upper connecting arm 31 can transmit the power to the lower connecting arm 32. The upper connecting arm 31 slides axially relative to the lower connecting arm 32, and the lower connecting arm 32 can rotate relative to the base 10, so that the vibration is converted into the form of the lower connecting arm 32 rotating relative to the base 10, which is conducive to the vibration reduction assembly 30 to decompose and eliminate the vibration, thereby reducing the transmission of vibration to the base 10.
[0034] Furthermore, the upper connecting arm 31 can slide along the axial direction of the lower connecting arm 32 relative to the lower connecting arm 32, so that when the lower connecting arm 32 rotates relative to the base 10, the distance between the upper end of the upper connecting arm 31 and the lower end of the lower connecting arm 32 can be changed, which can not only ensure the smooth rotation of the lower connecting arm 32 and the normal operation of the vibration reduction assembly 30, but also convert the vibration into the axial sliding motion of the upper connecting arm 31 relative to the lower connecting arm 32, which can further eliminate the vibration and reduce the transmission of the vibration to the base 10. A first spring member 33 is abutted between the upper end of the upper connecting arm 31 and the lower end of the lower connecting arm 32. The first spring member 33 is the main elastic element in the vibration reduction device 100 and is mainly used to absorb and eliminate the vibration transmitted to the vibration reduction device 100. In addition, the first spring member 33 can support the upper connecting arm 31 and the lower connecting arm 32. When the upper connecting arm 31 is sleeved on the circumferential outer side of the lower connecting arm 32, the first spring member 33 can ensure that the position of the upper connecting arm 31 relative to the lower connecting arm 32 is stable. When the upper connecting arm 31 slides axially relative to the lower connecting arm 32, the upper connecting arm 31 can transmit the vibration on the adapter block 20 to the first spring member 33. The first spring member 33 is cyclically squeezed and reset, which can repeatedly consume power and eliminate vibration. With such a configuration, the vibration reduction device 100 in the embodiment of the utility model can absorb and eliminate vibration to reduce the vibration transmitted to the vehicle body.
[0035] In the prior art, the rubber main spring suspension system is made of rubber material. After long-term operation, the rubber is not only easy to age, resulting in reduced elasticity, but also likely to crack and lose its vibration isolation capability. In addition, the rubber material is sensitive to temperature and is prone to thermal expansion at high temperatures, which accelerates material aging and affects the vibration isolation effect of the suspension.
[0036] In the embodiment of the utility model, the first spring member 33 is used to absorb vibration. The material of the first spring member 33 includes but is not limited to spring steel. Under the influence of long-term load and temperature change, spring steel is not easy to age, which can ensure the reliability of the first spring member 33, and further solve the problem that the traditional rubber main spring suspension is prone to aging and cracking. In addition, the form of the first spring member 33 includes but is not limited to a coil spring. The two ends of the coil spring can abut between the upper end of the upper connecting arm 31 and the lower end of the lower connecting arm 32, and can support the upper connecting arm 31 and the lower connecting arm 32. The coil spring has good elasticity and can convert force into elastic potential energy when compressed. Since one end of the adapter block 20 connected to the upper connecting arm 31 can move freely, the first spring member 33 can be reversed after being compressed. Reciprocating motion can make the first spring member 33 absorb kinetic energy and eliminate vibration.
[0037] Combination Figure 1-Figure 4As shown, the vibration reduction device 100 also includes a fastener 40, which passes through the adapter block 20 and the upper end of the upper connecting arm 31, and connects and fixes the upper end of the upper connecting arm 31 to the adapter block 20. Specifically, the fastener 40 is arranged to pass through the adapter plate on the adapter block 20 and the upper end of the upper connecting arm 31 in sequence, and the upper end of the upper connecting arm 31 can be connected and fixed to the adapter block 20, so that the upper connecting arm 31 can be prevented from rotating relative to the adapter block 20. If the upper connecting arm 31 rotates relative to the adapter block 20, during the movement of the vibration reduction assembly 30, the upper connecting arm 31 will hinder the lower connecting arm 32 from rotating relative to the base 10, and jamming will occur during the axial sliding of the upper connecting arm 31 relative to the lower connecting arm 32. With such a configuration, the vibration reduction assembly 30 can be ensured to move smoothly, and the vibration reduction effect of the vibration reduction device 100 can be ensured.
[0038] Furthermore, an axially extending slide groove 321 is provided at the upper end of the lower connecting arm 32, so that the upper end of the lower connecting arm 32 has a certain sliding space relative to the upper connecting arm 31, and the upper connecting arm 31 can slide relative to the lower connecting arm 32. The slide groove 321 is opened along the axial direction of the lower connecting arm 32, which can ensure the axial sliding of the upper connecting arm 31 relative to the lower connecting arm 32 along the lower connecting arm 32, and can prevent the upper connecting arm 31 from getting stuck when sliding relative to the lower connecting arm 32, thereby ensuring the normal operation of the vibration reduction assembly 30 and the vibration reduction effect of the vibration reduction device 100.
[0039] Further, the fastener 40 is provided with a slide groove 321 and can slide axially in the slide groove 321. Specifically, the fastener 40 is provided with the slide groove 321, so that the upper end of the lower connecting arm 32 can be sleeved on the fastener 40, so that the upper end of the lower connecting arm 32 can be connected to the upper end of the upper connecting arm 31, which can form the basic structure of the vibration reduction assembly 30, and further ensure that the upper connecting arm 31 is sleeved on the circumferential outer side of the lower connecting arm 32, which can facilitate the installation of the first spring member 33 in the vibration reduction assembly 30. The fastener 40 can slide axially in the slide groove 321, so that the upper connecting arm 31 can slide smoothly axially relative to the lower connecting arm 32, which is conducive to improving the movement reliability of the vibration reduction assembly 30.
[0040] In an embodiment of the utility model, a lubricant is applied between the fastener 40 and the slide groove 321 to ensure that the fastener 40 slides smoothly relative to the slide groove 321. Before applying the lubricant, a polymer coating can be applied on the circumferential outer side of the fastener 40 and the inner wall of the slide groove 321. The polymer coating includes but is not limited to polyurethane.
[0041] Combination Figure 4As shown, first buffer members 3211 are respectively provided on the inner walls at both axial ends of the slide groove 321 , and the first buffer member 3211 is selectively squeezed and buffered with the fastener 40 . Specifically, a first buffer member 3211 is arranged in the slide groove 321, and the first buffer member 3211 is arranged close to the inner wall of the slide groove 321. Such arrangement can, on the one hand, prevent the first buffer member 3211 from interfering with the axial sliding of the fastener 40 in the slide groove 321, and on the other hand, the first buffer member 3211 has a certain vibration absorption effect. When the fastener 40 slides axially in the slide groove 321 and approaches the inner wall of the slide groove 321, the first buffer member 3211 can not only prevent the fastener 40 from colliding with the inner wall of the slide groove 321 to produce abnormal noise, but can also be squeezed by the fastener 40 and cooperate with the fastener 40 for buffering. In this way, the first buffer member 3211 can absorb the power on the fastener 40, slow down the sliding of the fastener 40 in the slide groove 321, and thus help to absorb the vibration on the vibration reduction assembly 30, improve the vibration reduction efficiency of the vibration reduction assembly 30, and thus improve the vibration reduction effect of the vibration reduction device 100.
[0042] In an embodiment of the utility model, the lower end of the lower connecting arm 32 is set on the base 10 through the fastener 40, and a lubricant is applied between the fastener 40, the lower connecting arm 32 and the base 10 to ensure that the lower connecting arm 32 rotates smoothly relative to the base 10. Before applying the lubricant, a polymer coating can be applied at the contact position of the fastener 40, the lower connecting arm 32 and the base 10. The polymer coating includes but is not limited to polyurethane.
[0043] Combination Figure 4 As shown, there are two vibration reduction assemblies 30, and the two vibration reduction assemblies 30 are respectively arranged on the left and right sides of the adapter block 20. Specifically, the two vibration reduction assemblies 30 can support the adapter block 20, and the design position of the adapter block 20 in the vibration reduction device 100 can be set, which not only facilitates the connection of the adapter block 20 with other structures in the vehicle, but also avoids direct contact between the adapter block 20 and the base 10, so as to ensure the vibration reduction reliability of the vibration reduction device 100. In addition, the left and right directions of the adapter block 20 are each connected to a vibration reduction assembly 30, so that after the adapter block 20 receives power, the vibration can be transmitted to the left and right vibration reduction assemblies 30 at the same time, and the two vibration reduction assemblies 30 can absorb and eliminate vibration at the same time, thereby improving the working efficiency of the vibration reduction device 100 and improving the vibration reduction reliability of the vibration reduction device 100.
[0044] Combination Figure 2As shown, the lower end of the lower connecting arm 32 is provided with a lower abutting block 322, and the lower abutting block 322 is rotatably connected to the base 10. The upper end of the upper connecting arm 31 is provided with an upper abutting block 311, and the upper abutting block 311 is connected to the adapter block 20. The first spring member 33 is elastically abutted between the upper abutting block 311 and the lower abutting block 322. Specifically, the lower abutting block 322 on the lower connecting arm 32 can rotate relative to the base 10, so that the lower connecting arm 32 can rotate relative to the base 10. The upper abutting block 311 is provided at the upper end of the upper connecting arm 31, which can be used to connect with the adapter block 20, and can ensure that the upper connecting arm 31 does not rotate relative to the adapter block 20. In addition, both the upper abutment block 311 and the lower abutment block 322 can provide abutment positions for the first spring member 33. In this way, the first spring member 33 is arranged between the upper abutment block 311 and the lower abutment block 322, which can not only ensure the stability of the position of the first spring member 33 in the vibration reduction assembly 30 and protect the structural reliability of the first spring member 33, but also ensure that the first spring member 33 is in contact with the upper connecting arm 31 and the lower connecting arm 32, and can receive vibrations on the upper connecting arm 31 and the lower connecting arm 32 to absorb vibrations in the vibration reduction assembly 30.
[0045] Combination Figure 3 As shown, the upper end of the upper connecting arm 31 is provided with a through hole 312, and at least part of the upper end of the lower connecting arm 32 selectively extends out from the through hole 312. Specifically, during the axial sliding of the upper connecting arm 31 relative to the lower connecting arm 32, the distance between the upper end of the upper connecting arm 31 and the lower end of the lower connecting arm 32 will be shortened. The through hole 312 is provided at the upper end of the upper connecting arm 31, so that when the distance between the upper end of the upper connecting arm 31 and the lower end of the lower connecting arm 32 is shortened, the upper end of the lower connecting arm 32 can at least partially extend out from the through hole 312, thereby preventing the lower connecting arm 32 from being stuck when rotating relative to the base 10, and ensuring the movement reliability of the vibration reduction device 100. When the distance between the upper end of the upper connecting arm 31 and the lower end of the lower connecting arm 32 is extended, the upper end of the lower connecting arm 32 can be retracted into the through hole 312.
[0046] Combination Figure 2 and Figure 4As shown, the lower end of the adapter block 20 is provided with a second buffer 21, and the second buffer 21 selectively compresses and buffers with the base 10. Specifically, in the vibration reduction device 100, the two vibration reduction assemblies 30 can support and limit the left and right directions of the adapter block 20, and the fastener 40 between the adapter block 20 and the upper connecting arm 31 can limit the front and rear directions of the adapter block 20, so that the adapter block 20 will move in the up and down directions under the vibration, and the base 10 is located below the adapter block 20. The second buffer 21 is provided at the lower end of the adapter block 20, and the second buffer 21 has a certain vibration absorption effect. In this way, when the adapter block 20 moves downward and collides with the base 10, the second buffer 21 can buffer and cooperate with the base 10, and in the path of the vibration transmission from the adapter block 20 to the base 10, a part of the vibration can be absorbed by the second buffer 21, so that the vibration transmission to the base 10 can be reduced, and the vibration reduction reliability of the vibration reduction device 100 can be ensured to reduce the vibration transmission to the vehicle body. In the embodiment of the present invention, the second buffer member 21 can be provided or not according to the vibration reduction requirement of the vehicle.
[0047] Combination Figure 1-Figure 4 As shown, the vibration reduction device 100 also includes a support arm 50, and the support arm 50 is provided with an adapter block 20 in the front-to-back direction, and is spaced apart from the vibration reduction assembly 30, and the front end of the support arm 50 is used to connect the powertrain. Specifically, the support arm 50 is connected to the powertrain components of the vehicle, and the support arm 50 is provided with an adapter block 20 in the front-to-back direction, so that the power can be transmitted to the adapter block 20, and then the vibration can be transmitted to the vibration reduction device 100, so that the vibration reduction device 100 absorbs and eliminates the vibration. The support arm 50 and the vibration reduction assembly 30 are spaced apart from each other, so that the vibration is transmitted to the vibration reduction assembly 30 through the adapter block 20, and then the vibration can be transmitted to the first spring member 33 in a set direction, so that the vibration reduction effect of the first spring member 33 on the vibration can be ensured.
[0048] Furthermore, a spring mounting seat 51 is provided at the front end of the support arm 50, and a second spring member 52 is elastically abutted between the spring mounting seat 51 and the adapter block 20, so that the second spring member 52 can support the support arm 50 and the adapter block 20 in the front-to-back direction, and can ensure the reliability of the relative position of the support arm 50 and the adapter block 20 in the front-to-back direction. The second spring member 52 has a certain elasticity. When the vibration is transmitted to the adapter block 20 through the support arm 50, the support arm 50 moves relative to the adapter block 20 in the front-to-back direction, and the second spring member 52 is squeezed and reset cyclically, so that power can be repeatedly consumed, thereby eliminating vibration. Such a setting can enable the vibration reduction device 100 in the embodiment of the utility model to absorb and eliminate vibration, so as to reduce the vibration transmitted to the vehicle body. In the embodiment of the utility model, the second spring member 52 can be selected whether to be provided according to the vibration reduction requirements of the vehicle.
[0049] In an embodiment of the utility model, a lubricant is applied between the contact position of the support arm 50 and the adapter block 20, so that the support arm 50 can slide smoothly relative to the adapter block 20. Before applying the lubricant, a polymer coating can be applied to the contact position of the support arm 50 and the adapter block 20. The polymer coating includes but is not limited to polyurethane.
[0050] Combination Figure 1-Figure 3 As shown, the rear side of the base 10 is provided with a side plate 11, and the rear end of the support arm 50 is provided with a third buffer 53, and the third buffer 53 selectively compresses and buffers the side plate 11. Specifically, in order to ensure the connection reliability between the vibration reduction device 100 and the vehicle body, the rear side of the base 10 is provided with a side plate 11, and the rear end of the support arm 50 is opposite to the side plate 11, and is arranged at a distance. In the process of the support arm 50 moving forward and backward, the support arm 50 will hit the side plate 11, which will directly transmit the vibration to the base 10, resulting in a reduction in the vibration reduction effect of the vibration reduction device 100. The third buffer 53 is provided at the rear end of the support arm 50, and the third buffer 53 has a certain vibration absorption effect. When the support arm 50 hits the side plate 11, a part of the vibration can be absorbed by the third buffer 53 in the path of the transmission from the adapter block 20 to the base 10, so that the vibration can be reduced to the side plate 11, and the vibration reduction reliability of the vibration reduction device 100 can be ensured to reduce the vibration transmission to the vehicle body.
[0051] According to the embodiment of the utility model, the vibration reduction device 100 can be applied to a vehicle. Two vibration reduction assemblies 30 are provided in the vibration reduction device 100 to support and limit the left and right directions of the adapter block 20. A first spring member 33 is provided on each of the two vibration reduction assemblies 30. A second spring member 52 is provided between the support arm 50 and the adapter block 20. In this way, the vibration in the vehicle can be absorbed and eliminated by the first spring member 33 and the second spring member 52, which can replace the rubber main spring suspension in the prior art. The first spring member 33 and the second spring member 52 will not age under the influence of long-term load and temperature changes, and the reliability is higher, thereby improving the reliability of the vibration reduction device 100.
[0052] In the embodiment of the utility model, the cross-sectional area, effective number of turns, spring length and spring direction of the first spring member 33 and the second spring member 52 can be designed according to the actual vibration reduction requirements of the vehicle. By designing the cross-sectional area, effective number of turns, spring length and spring direction of the first spring member 33 and the second spring member 52, the stiffness of the first spring member 33 and the second spring member 52 can be adjusted to meet the vibration reduction requirements of different vehicle models under different working conditions.
