DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 4As shown, the device includes a frame 1, a support plate 2 and a mounting hole 3. The support plate 2 is slidably connected to the upper end of the frame 1. The mounting holes 3 are integrally arranged at the four corners of the support plate 2. A partition plate 4 is fixedly arranged at the middle end of the frame 1. A buffer assembly 5 is arranged at the bottom of the support plate 2. The buffer assembly 5 includes mounting rods 501 fixedly arranged on the left and right sides of the bottom of the support plate 2. The mounting rods 501 slide through the partition plate 4. A first spring 502 is sleeved on the outside of the mounting rods 501. Mounting blocks 503 are slidably connected to the left and right sides of the bottom end of the frame 1. Second springs 504 are fixedly arranged at the front and rear ends between the mounting blocks 503. A top plate 505 is connected inside the mounting block 503. The end of the top plate 505 away from the mounting block 503 is connected to the bottom of the mounting rod 501.

[0029] The top of the first spring 502 is fixedly connected to the bottom of the support plate 2 , and the bottom of the first spring 502 is fixedly connected to the top of the partition 4 . The first spring 502 and the second spring 504 are in a vertical design state, and the rebound force of the first spring 502 is greater than the rebound force of the second spring 504 . First, a mounting hole 3 is provided inside the support plate 2 so that the drive motor can be installed on the support plate 2 through the mounting hole 3. When the drive motor is vibrated, the drive motor drives the support plate 2 together with the mounting rod 501 to move downward along the direction of the partition plate 4, so that the first spring 502 is deformed. Because the rebound force of the first spring 502 is greater than the rebound force of the second spring 504, at this time, the mounting rod 501 pushes the top plate 505 together with the deformed second spring 504 to reset. At the same time, the deformed first spring 502 generates a rebound force, and then the first spring 502 drives the support plate 2 together with the mounting rod 501 and the top plate 505 to reset. At this time, the first spring 502 during the reset pulls the second spring 504 to deform. The resistance formed by the rebound force of the second spring 504 reduces the frequency of the first spring 502 rebounding, that is, the frequency of the drive motor vibration is reduced.

[0030] Example 2

[0031] like Figure 2 , Figure 3 , Figure 5As shown, the top of the first spring 502 is fixedly connected to the bottom of the support plate 2, the bottom of the first spring 502 is fixedly connected to the top of the partition 4, the first spring 502 and the second spring 504 are in a vertical design state, the resilience of the first spring 502 is greater than the resilience of the second spring 504, the left and right sides of the lower end of the frame 1 are connected with a rotating rod 6, the outer sleeve of the rotating rod 6 is fixedly provided with a gear 8, the lower end of the outer side of the mounting rod 501 is fixedly provided with a first rack 9, the end of the first rack 9 away from the mounting rod 501 slides through the partition 4, and the first rack 9 is in gear meshing with the gear 8 The design comprises that the top surface of the first rack 9 is fixedly connected to the bottom surface of the support plate 2, a first rubber pad 10 is fixedly provided on the outer wall of the first rack 9, a slide groove 11 is integrally provided on the left and right sides of the lower end of the frame 1, a slider 12 is slidably connected inside the slide groove 11, a second rack 13 is fixedly provided on the inner side of the slider 12, an end of the second rack 13 away from the slider 12 slides through the partition 4, the second rack 13 and the first rack 9 are in a parallel design state, the second rack 13 is meshed with the gear teeth of the gear 8, a connecting plate 14 is fixedly provided on the top of the second rack 13, and a second rubber pad 15 is fixedly provided on the top of the connecting plate 14.

[0032] According to the operation method in Example 1, when the support plate 2 drives the mounting rod 501 to move downward along the direction of the partition 4, the mounting rod 501 drives the first rack 9 together with the gear 8 and the rotating rod 6 to rotate, so that the gear 8 drives the second rack 13 together with the slider 12 to move upward along the direction of the slide groove 11, so that the second rack 13 drives the connecting plate 14 together with the second rubber pad 15 to contact the support plate 2, the purpose of which is to limit the downward movement distance of the support plate 2. When the first spring 502 drives the support plate 2 to reset, the first rack 9 drives the gear 8 together with the second rack 13 and the slider 12 to reset, and the first rack 9 drives the first rubber pad 10 to contact the partition 4, thereby ensuring the stability of the support plate 2 after the reset.
