[0056] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of an EGR valve mounting bracket that can prevent vibration.

[0057] A vibration-proof EGR valve mounting bracket includes a mounting plate 1, an EGR valve body 2, and further includes:

[0058] An adjustment component, disposed on the mounting plate 1, is used to adjust the length of the fixed bracket. The adjustment component includes:

[0059] Lead screw 3 is rotatably connected to the mounting plate 1;

[0060] Knob 4 is fixedly connected to the lead screw 3;

[0061] The support shell 5 is disposed on the mounting plate 1 and is fixedly connected to the mounting plate 1;

[0062] The sliding plate 6 is mounted on the support shell 5 and is slidably connected to the support shell 5.

[0063] Adjusting plate 7 is fixedly connected to the slide plate 6. Adjusting plate 7 is threadedly connected to the lead screw 3 and slidably connected to the support shell 5.

[0064] The knob 4 is turned, which in turn drives the lead screw 3, which is fixedly connected to the knob 4, to rotate. The rotation of the lead screw 3 causes the adjusting plate 7, which is threadedly connected to the lead screw 3 and restricted by the sliding support shell 5, to slide. This causes the sliding plate 6, which is fixedly connected to the adjusting plate 7, to slide along the support shell 5 until the desired installation position is reached, thereby achieving the effect of adjusting the installation position.

[0065] With the cooperation of the adjustment components, the rotating knob 4 drives the lead screw 3 to rotate, which in turn drives the adjustment plate 7 to move. This causes the slide plate 6, which is fixedly connected to the adjustment plate 7, to slide along the support shell 5, thereby adjusting the length of the fixed bracket and expanding the applicability of the fixed bracket.

[0066] A locking component, disposed on the mounting plate 1, is used to lock the adjustment component. The locking component includes:

[0067] The first locking block 8 is slidably connected to the mounting plate 1, and the surface of the first locking block 8 in contact with the lead screw 3 is very rough.

[0069] The first screw 10 is threadedly connected to the first locking block 8, and the first screw 10 is threadedly connected to the mounting plate 1.

[0070] The second screw 11 is threaded onto the second locking block 9, and the second screw 11 is threaded onto the mounting plate 1.

[0071] Next, push the first locking block 8 and the second locking block 9 to move towards the lead screw 3 respectively until the first locking block 8 and the second locking block 9 are in close contact with the lead screw 3. Then screw the first screw 10 into the threaded first locking block 8 and the threaded mounting plate 1 until tightened. Then screw the second screw 11 into the threaded second locking block 9 and the threaded mounting plate 1 until tightened, so as to further fix the lead screw 3.

[0072] Reference Figures 1 to 5 A mounting component, disposed on the regulating component, is used to mount the EGR valve body 2. The mounting component includes:

[0073] Movable plate 12 is mounted on the slide plate 6 and is fixedly connected to the slide plate 6;

[0074] The mounting platform 13 is slidably connected to the movable plate 12, and the mounting platform 13 is rotatably connected to the lead screw 3;

[0075] The first mounting frame 14 is fixedly connected to the mounting platform 13;

[0076] The second mounting frame 15 is disposed on the first mounting frame 14 and is rotatably connected to the first mounting frame 14.

[0077] A fixing component, disposed on the mounting component, is used to fix the mounting component, the fixing component comprising:

[0078] The fixing block 16 is fixedly connected to the second mounting frame 15;

[0079] Fixing hole 17 is provided on the fixing block 16;

[0080] A fixing bolt 18 is disposed on the fixing hole 17, the fixing bolt 18 is threadedly connected to the fixing block 16, and the fixing bolt 18 is fixedly connected to the first mounting frame 14;

[0081] The limiting bolt 19 is threadedly connected to the fixing block 16, and the limiting bolt 19 is threadedly connected to the fixing bolt 18.

[0082] Open the second mounting frame 15, place the EGR valve body 2 on the first rubber shock-absorbing pad 24, close the second mounting frame 15, screw the fixing bolt 18 into the mounting hole, and screw it into the threaded first mounting frame 14 until it is tightened. Then screw the limit bolt 19 into the fixing block 16 until the limit bolt 19 passes through the threaded fixing bolt 18 and tighten it, thereby achieving the effect of installing and fixing the EGR valve body 2.

[0083] Reference Figures 1 to 5 A vibration damping component, disposed on the mounting assembly, is used to prevent vibration of the EGR valve body 2. The vibration damping component includes:

[0084] The first connecting block 20 is fixedly connected to the first mounting frame 14;

[0085] The second connecting block 21 is fixedly connected to the second mounting frame 15;

[0086] The first shock-absorbing spring 22 is disposed on the first mounting frame 14 and is fixedly connected to the first mounting frame 14;

[0087] The second damping spring 23 is disposed on the second mounting frame 15 and is fixedly connected to the second mounting frame 15;

[0088] The first rubber shock-absorbing pad 24 is fixedly connected to the first connecting block 20, and the first rubber shock-absorbing pad 24 is fixedly connected to the first shock-absorbing spring 22.

[0089] The second rubber shock-absorbing pad 25 is fixedly connected to the second connecting block 21, and the second rubber shock-absorbing pad 25 is fixedly connected to the second shock-absorbing spring 23.

[0090] The vibration generated by the EGR valve is first partially absorbed and consumed by the first rubber damping pad 24 and the second rubber damping pad 25 that are tightly attached to the EGR valve. Then, the excess vibration is absorbed and consumed by the first damping spring 22 and the second damping spring 23 that are fixedly connected to the first rubber damping pad 24 and the second rubber damping pad 25 respectively, thereby preventing the vibration generated by the EGR valve from causing the fixed bracket to vibrate.

[0091] Working principle: Refer to Figures 1 to 5 Open the second mounting frame 15, place the EGR valve body 2 on the first rubber shock-absorbing pad 24, close the second mounting frame 15, screw the fixing bolt 18 into the mounting hole, and screw it into the threaded first mounting frame 14 until it is tightened. Then screw the limit bolt 19 into the fixing block 16 until the limit bolt 19 passes through the threaded fixing bolt 18 and tighten it, thereby achieving the effect of installing and fixing the EGR valve body 2.

[0092] If the installation position of the EGR valve body 2 needs to be adjusted, turn the knob 4, thereby driving the lead screw 3 fixedly connected to the knob 4 to rotate. The rotation of the lead screw 3 causes the adjusting plate 7, which is threadedly connected to the lead screw 3 and restricted by the sliding support shell 5, to slide. This causes the sliding plate 6, which is fixedly connected to the adjusting plate 7, to slide along the support shell 5 until the desired installation position is reached, thereby achieving the effect of adjusting the installation position. Then, push the first locking block 8 and the second locking block 9 to move towards the lead screw 3 respectively, until the first locking block 8 and the second locking block 9 are in close contact with the lead screw 3. Then, screw the first screw 10 into the threaded first locking block 8 and the threaded mounting plate 1 until tightened. Then, screw the second screw 11 into the threaded second locking block 9 and the threaded mounting plate 1 until tightened, thereby further fixing the lead screw 3.

[0093] Reference Figures 1 to 5 When the EGR valve is working, the vibration generated by the EGR valve is first absorbed and consumed by the first rubber damping pad 24 and the second rubber damping pad 25 that are close to the EGR valve. Then, the excess vibration is absorbed and consumed by the first damping spring 22 and the second damping spring 23 that are fixedly connected to the first rubber damping pad 24 and the second rubber damping pad 25 respectively, so as to prevent the vibration generated by the EGR valve from causing the fixed bracket to vibrate.

[0094] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
