Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a vibration reduction component and a vehicle. Background Art

[0002] The built-in buffer block of the shock absorber is mostly installed by interference fit with the piston rod or by clip fit with the upper support. Its function is to limit compression, absorb energy, attenuate impact, ensure suspension travel and clearance of moving parts, and improve the comfort and safety of the vehicle.

[0003] In the related art, there are two main installation forms for the existing shock absorber buffer blocks. One is that the buffer block is in interference fit with the piston rod. When the buffer block is compressed, it will cause friction with the piston rod, which is easy to produce abnormal noise. The general solution is to apply grease on the inner wall of the buffer block, but when the grease is applied less, abnormal noise will still be produced, which does not fundamentally solve the problem. The other is that the buffer block is clamped with the bottom cup of the upper support, in which the outer wall of the buffer block is in interference fit with the inner wall of the upper support. When the shock absorber swings, the buffer block rubs against the bottom of the upper support, which may produce abnormal noise. In addition, when the shock absorber swings at a large angle, the buffer block is easy to fall off, resulting in abnormal noise. Utility Model Content

[0027] 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.

[0028] Reference below Figure 1-Figure 4 A vibration reduction assembly according to an embodiment of the present invention is described.

[0029] There are two main installation forms for existing shock absorber buffer blocks. One is that the buffer block is in interference fit with the piston rod. When the buffer block is compressed, it will cause friction with the piston rod, which is easy to produce abnormal noise. The general solution is to apply grease on the inner wall of the buffer block, but when the grease is applied less, abnormal noise will still be produced, which does not fundamentally solve the problem. The other is that the buffer block is clamped with the bottom cup of the upper support, in which the outer wall of the buffer block is in interference fit with the inner wall of the upper support. When the shock absorber swings, the buffer block rubs against the bottom of the upper support, which may produce abnormal noise. In addition, since the outer wall of the buffer block and the inner wall of the upper support are in surface contact, when the shock absorber swings at a large angle, it is easy for the buffer block to fall off, resulting in abnormal noise.

[0030] like Figure 1-Figure 4 As shown, the vibration reduction assembly includes: an upper support member 1 and a buffer member 2.

[0031] A first plug-in portion 11 is provided on one end surface of the upper support member 1, and a second plug-in portion 21 is provided on the end surface of the buffer member 2 facing the upper support member 1. The buffer member 2 and the upper support member 1 are fixedly matched by plugging the first plug-in portion 11 and the second plug-in portion 21.

[0032] like Figure 2As shown, the upper support member 1 and the buffer member 2 are arranged opposite to each other, and a first plug-in portion 11 is provided on the end surface of the upper support member 1 facing the buffer member 2, and a second plug-in portion 21 is provided on the end surface of the buffer member 2 facing the upper support member 1 to be plugged and matched with the first plug-in portion 11. The first plug-in portion 11 and the second plug-in portion 21 are plug-fitted to achieve a fixed fit between the buffer member 2 and the upper support member 1.

[0033] Compared with the existing first installation form: the buffer block and the piston rod are fixed by interference fit, the vibration reduction assembly of the present application can avoid the problem of abnormal noise caused by friction between the inner wall of the buffer part 2 and the piston rod. Compared with the existing second installation form: the outer wall of the buffer block and the inner wall of the upper support are interference fit, the vibration reduction assembly of the present application can increase the swing angle of the buffer part 2 when it is subjected to force, is not easy to fall off, and can avoid the problem of abnormal noise caused by friction between the outer wall and the upper support part 1 when the buffer part 2 swings.

[0034] The upper support member 1 can be fixedly connected to the vehicle body structure, so as to fix the vibration reduction assembly on the vehicle body structure, and complete the installation and fixation of the vibration reduction assembly. When the vehicle passes through a pit or a bump, the vibration reduction assembly can buffer the impact force on the vehicle and reduce vibration, providing a comfortable riding experience for the user. In addition, the buffer member 2 can be a buffer block.

[0035] Therefore, the upper support member 1 and the buffer member 2 are fixed by plug-in cooperation. When the buffer member 2 is compressed, the problem of abnormal noise caused by friction between the inner wall of the buffer member 2 and the piston rod can be avoided, the swing angle of the buffer member 2 when subjected to force can be increased, and the problem of abnormal noise caused by friction between the outer wall of the buffer member 2 and the upper support member 1 can be avoided when the buffer member 2 swings.

[0036] Furthermore, the outer side wall of the first plug-in portion 11 is plug-fitted with the inner side wall of the second plug-in portion 21 .

[0037] Specifically, when the vehicle passes a pit or a bump, the wheels will bounce up and down, the shock absorber will follow the bouncing of the wheels and move back and forth up and down, the connecting rod 3 inside the shock absorbing assembly will swing accordingly, and the swing angle of the connecting rod 3 will increase the force on the buffer 2, causing the buffer 2 to deform. Inserting the first plug-in portion 11 of the upper support 1 into the second plug-in portion 21 of the buffer 2 can effectively prevent the buffer 2 from falling off due to the excessive swing angle of the connecting rod 3, thereby avoiding the problem of abnormal noise.

[0038] Compared with the outer wall of the second plug-in portion 21 being plugged into the inner wall of the first plug-in portion 11 , the installation form of the present application can ensure a more secure fit between the upper support member 1 and the buffer member 2 .

[0039] Furthermore, the dimension of the first plug-in portion 11 in the height direction is smaller than the dimension of the second plug-in portion 21 in the height direction.

[0040] That is, when the first plug-in portion 11 is inserted into the second plug-in portion 21 , the bottom of the first plug-in portion 11 does not contact the bottom of the second plug-in portion 21 , which can prevent the buffer member 2 from being damaged by the upper support member 1 when compressed.

[0041] Furthermore, the first plug-in portion 11 and the second plug-in portion 21 are in interference fit.

[0042] In this way, the interference fit between the first plug-in portion 11 and the second plug-in portion 21 can effectively avoid the problem of abnormal noise caused by the vertical impact of the buffer component 2 caused by the rapid bounce of the wheel when passing through a pit or a bump.

[0043] Further, the first plug-in portion 11 is one of a socket and a column, and the second plug-in portion 21 is the other of the socket and the column, and the socket and the column are plug-fitted.

[0044] As a preferred embodiment, Figure 2-Figure 4 As shown, a plug post is provided on the end surface of the upper support member 1 to serve as a first plug-in portion 11, and a socket is provided on the end surface of the buffer member 2 to serve as a second plug-in portion 21, and the socket is plugged and matched with the plug post.

[0045] Furthermore, the plug post is cylindrical and the plug hole is a cylindrical hole, which can prevent the buffer member 2 from being damaged by the upper support member 1 when compressed. In addition, it is convenient for manufacturing and installation, improves production efficiency and saves costs.

[0046] Of course, the first plug-in portion 11 and the second plug-in portion 21 include but are not limited to the above-mentioned embodiments.

[0047] Furthermore, at least two radially opposite first plug-in portions 11 are provided on the end surface of the upper support member 1, and at least two radially opposite second plug-in portions 21 are provided on the end surface of the buffer member 2 facing the upper support member 1, and the first plug-in portions 11 correspond to the second plug-in portions 21.

[0048] Specifically, on the end surface of the upper support member 1, two first plug-in portions 11 are arranged opposite to each other in the radial direction, and correspondingly, on the end surface of the buffer member 2, second plug-in portions 21 corresponding to the two first plug-in portions 11 are arranged, which can ensure that the mutual cooperation between the upper support member 1 and the buffer member 2 is more stable. That is, the assembly between the upper support member 1 and the buffer member 2 is more stable.

[0049] Two radially opposite first plug-in parts 11 form a group. At least one group of first plug-in parts 11 is arranged on the end surface of the upper support member 1. Correspondingly, at least one group of second plug-in parts 21 is arranged on the end surface of the buffer member 2 to be plugged and matched therewith.

[0050] refer to Figure 2 and Figure 4As shown, a first annular chamber 12 is formed on the end surface of the upper support member 1, a first plug-in portion 11 is provided on the bottom wall of the first annular chamber 12, and the outer wall of the buffer member 2 facing one end of the upper support member 1 is gap-matched with the inner wall of the first annular chamber 12.

[0051] In this way, the outer wall of the buffer 2 is gap-matched with the inner wall of the first annular chamber 12, and the bottom wall of the first annular chamber 12 is plug-fitted with the end of the buffer 2. When the connecting rod 3 is forced to swing, one end of the buffer 2 can be limited and movable in the first annular chamber 12 without generating friction noise. Compared with the second installation method in the prior art, the vibration reduction assembly of the present application increases the swing angle of the buffer 2 when it is forced, is not easy to fall off, and can also avoid the problem of friction noise between the outer wall and the upper support 1 when the buffer 2 swings.

[0052] Furthermore, the first plug-in portion 11 is integrally formed on the upper support member 1 ; and / or the second plug-in portion 21 is integrally formed on the buffer member 2 .

[0053] In this way, the first plug-in portion 11 is integrally formed on the upper support member 1, and the second plug-in portion 21 is integrally formed on the buffer member 2, which can improve the structural strength of the first plug-in portion 11 and the second plug-in portion 21, facilitate manufacturing and installation, and save costs.

[0054] For example, two cylinders are added to the upper support member 1, and the upper support member 1 is integrally formed during casting. Two cylindrical holes are added to the buffer member 2, and cylindrical features are added to the casting mold of the buffer member 2.

[0055] Furthermore, the vibration reduction assembly also includes: a connecting rod 3, a mounting hole 14 is provided in the upper support member 1, the connecting rod 3 passes through the mounting hole 14 and is connected to the upper support member 1, and the connecting rod 3 and the mounting hole 14 are clearance-matched, and the buffer member 2 and the connecting rod 3 are clearance-matched.

[0056] refer to Figure 2 As shown, the connecting rod 3 is installed and matched with the upper support member 1 through the installation hole 14, and the connecting rod 3 and the installation hole 14 are clearance matched, and the buffer member 2 and the connecting rod 3 are clearance matched, so that the problem of abnormal friction noise will not occur when the connecting rod 3 swings.

[0057] In addition, the end surface of the upper support member 1 facing away from the buffer member 2 is provided with a concave second annular chamber 13, and the second annular chamber 13 is provided with a rubber bushing, which is sleeved on the top of the connecting rod 3. The mounting hole 14 is connected to the first annular chamber 12 and the second annular chamber 13, so that the connecting rod 3 passes through the upper support member 1.

[0058] A vehicle according to an embodiment of the second aspect of the utility model includes: a vibration reduction assembly applicable to a suspension.

[0059] Therefore, the upper support member 1 and the buffer member 2 are fixed by plug-in cooperation. When the buffer member 2 is compressed, the problem of abnormal noise caused by friction between the inner wall of the buffer member 2 and the connecting rod 3 can be avoided, the swing angle of the buffer member 2 under force can be increased, and the problem of abnormal noise caused by friction between the outer wall and the upper support member 1 when the buffer member 2 swings can be avoided.
