Description

Technical Field

[0001] The utility model relates to the technical field of drum washing machines, in particular to a shock-absorbing and noise-reducing track base for facilitating the insertion and placement of a drum washing machine. Background Technique

[0002] A drum washing machine is a household appliance designed for washing clothes. Compared with traditional agitator washing machines, it uses a rotating drum instead of a stirring rod to agitate the clothes, thus providing a gentler and more efficient washing method.

[0003] Currently, in order to avoid generating excessive noise and vibration during the operation of a drum washing machine, the drum is usually installed on a track base, and dampers are usually used on the track base for shock absorption and noise reduction. The dampers are usually installed between the drum and the suspension system, or at the part where the bottom of the washing machine contacts the ground.

[0004] However, when the existing drum washing machine runs at high speed, the drum still generates significant noise and vibration due to hitting the washing machine body. Therefore, the utility model proposes a shock-absorbing and noise-reducing track base for facilitating the insertion and placement of a drum washing machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shock-absorbing and noise-reducing track base for facilitating the insertion and placement of a drum washing machine, so as to solve the problem that the drum of the existing drum washing machine in the prior art still generates significant noise and vibration due to hitting the washing machine body during high-speed operation as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A shock-absorbing and noise-reducing track base for facilitating the insertion and placement of a drum washing machine, the shock-absorbing and noise-reducing track base for facilitating the insertion and placement of a drum washing machine includes:

[0007] A track base main body, one end of the track base main body is fixedly connected with a protective side wall, and one end of the protective side wall is provided with a plurality of shock-absorbing and noise-reducing strengthening components distributed in a circumferential array;

[0008] The shock absorption, noise reduction and strengthening component includes a mounting rod, which is located at one end of the protective side wall and fixedly connected to the protective side wall. An oil storage cavity and an installation cavity for installing and storing hydraulic oil are provided inside the mounting rod. A diversion groove arranged in a "spiral shape" is communicated between the oil storage cavity and the installation cavity. A first baffle is slidably and sealingly connected to the inner cavity of the oil storage cavity. One end of the first baffle is fixedly connected to a force transmission rod that is slidably inserted into the mounting rod. A second baffle is slidably and sealingly connected to the inner cavity of the installation cavity. A third spring is fixedly connected between the second baffle and the mounting rod. A force transmission block arranged in a "triangular prism" shape is slidably inserted into one side of the mounting rod. The inclined surface of the force transmission block contacts the force transmission rod, and one end of the force transmission block is fixedly connected to a mounting plate. A plurality of first springs are fixedly connected between the mounting plate and the mounting rod, and a third rubber pad is fixedly connected to the side of the mounting plate that contacts the roller. A second rubber pad is fixedly connected to the side of the mounting rod that contacts the washing machine body.

[0009] Preferably, a first rubber pad is fixedly connected to the side of the mounting rod that contacts the roller, and a cotton pad is fixedly connected to the end of the second rubber pad that contacts the washing machine body.

[0010] Preferably, a slider arranged in a "T" shape is fixedly connected to one side of the force transmission block, and the slider is slidably inserted into the mounting rod.

[0011] Preferably, a notch for the force transmission block to be slidably inserted is provided on one side of the mounting rod, and a chute for the slider to be slidably inserted is communicated with one side of the notch.

[0012] Preferably, a plurality of telescopic rods are fixedly connected between the mounting plate and the mounting rod, and the first springs are sleeved on the telescopic rods.

[0013] Preferably, a plurality of fourth rubber pads are fixedly connected to the side of the mounting plate that contacts the mounting rod. The side of the third rubber pad that contacts the washing machine is arranged in an "arc shape". A second spring is fixedly connected between the first baffle and the mounting rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The device is provided with multiple shock-absorbing and noise-reducing strengthening components distributed in a circumferential array at one end of the protective side wall. The shock-absorbing and noise-reducing strengthening components are distributed between the drum and the washing machine body. Therefore, the drum will collide with the shock-absorbing and noise-reducing strengthening components, and then the shock-absorbing and noise-reducing strengthening components will collide with the washing machine body. When the shock-absorbing and noise-reducing strengthening components collide with both, they will utilize the viscosity of the hydraulic oil through multiple structures, slots and the cooperation of the hydraulic oil to absorb the vibrations generated during the collision. And through multiple rubber pads arranged on the shock-absorbing and noise-reducing strengthening components, the noise generated by the collision is reduced as much as possible, thus greatly eliminating the vibrations and noises generated when the drum washing machine rotates at high speed. This solves the problem that in the prior art, the drum of the drum washing machine still generates relatively large noises and vibrations when colliding with the washing machine body during high-speed operation.

However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments may be used in combination with each other.

[0024] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0025] Embodiment 1, a shock-absorbing and noise-reducing track base for facilitating the insertion of a drum washing machine. The shock-absorbing and noise-reducing track base for facilitating the insertion of a drum washing machine includes: a track base main body 1, a protective side wall 2, and a shock-absorbing and noise-reducing strengthening component 3.

[0026] Specifically, one end of the track base main body 1 is fixedly connected to a protective side wall 2, and one end of the protective side wall 2 is provided with a plurality of shock-absorbing and noise-reducing strengthening components 3 distributed in a circumferential array;

[0027] Further, the shock absorption and noise reduction enhancement component 3 includes a mounting rod 4. The mounting rod 4 is located at one end of the protective side wall 2 and is fixedly connected to the protective side wall 2. An oil storage cavity 41 and an installation cavity 42 for installing and storing hydraulic oil are formed inside the mounting rod 4. The oil storage cavity 41 and the installation cavity 42 can provide a sealed installation environment for the hydraulic oil. A diversion groove 48 arranged in a "spiral shape" is communicated between the oil storage cavity 41 and the installation cavity 42. When the hydraulic oil is squeezed, it will flow from the oil storage cavity 41 to the installation cavity 42 through the diversion groove 48. The "spiral-shaped" diversion groove 48 can increase the contact area between the hydraulic oil and the mounting rod 4 by increasing the length of the hydraulic oil flow, so as to further exert the viscous force of the hydraulic oil. And the diameter of the diversion groove 48 is small, which will produce a small hole damping phenomenon, thus effectively improving the shock absorption and noise reduction effect of the shock absorption and noise reduction enhancement component 3. A first baffle 8 is slidably and sealingly connected to the inner cavity of the oil storage cavity 41. One end of the first baffle 8 is fixedly connected to a force transmission rod 7 that is slidably inserted into the mounting rod 4. A second baffle 9 is slidably and sealingly connected to the inner cavity of the installation cavity 42. A third spring 91 is fixedly connected between the second baffle 9 and the mounting rod 4. A force transmission block 5 arranged in a "triangular prism" shape is slidably inserted into one side of the mounting rod 4. Such a force transmission block 5 can well push the force transmission rod 7 to slide. The inclined surface of the force transmission block 5 contacts the force transmission rod 7 and one end of the force transmission block 5 is fixedly connected to a mounting plate 6. A plurality of first springs 63 are fixedly connected between the mounting plate 6 and the mounting rod 4, and a third rubber pad 61 is fixedly connected to the side of the mounting plate 6 in contact with the roller. When the roller shakes, it will hit the third rubber pad 61, and then the mounting plate 6 will push the force transmission block 5 to slide. When the force transmission block 5 slides, it will push the force transmission rod 7 to slide. When the force transmission rod 7 slides, it will push the first baffle 8 to compress the hydraulic oil and flow towards the installation cavity 42. When the roller is separated from the third rubber pad 61, the second baffle 9 will be pushed by the third spring 91 to slide, forcing the hydraulic oil to flow from the installation cavity 42 to the oil storage cavity 41 through the diversion groove 48, so as to push the first baffle 8, the force transmission rod 7, the force transmission block 5 and the mounting plate 6 to reset. And the first springs 63 can further help the mounting plate 6 to reset and buffer a certain amount of the impact force generated by the collision. The third rubber pad 61 can reduce the noise generated by the collision between the roller and the mounting plate 6. A second rubber pad 46 is fixedly connected to the side of the mounting rod 4 in contact with the washing machine body. The second rubber pad 46 can reduce the noise generated by the collision between the mounting rod 4 and the washing machine body.

[0028] To further improve the noise reduction effect of the mounting rod 4, a first rubber pad 45 is fixedly connected to one side of the mounting rod 4 in contact with the roller. After the roller and the mounting plate 6 collide and cause the mounting plate 6 to slide, the first rubber pad 45 will come into contact with the roller, thereby buffering the impact force of the roller and further reducing the noise generated by the collision. One end of the second rubber pad 46 in contact with the washing machine body is fixedly connected with a cotton pad 47. Due to its softness, the cotton pad 47 can effectively protect the body and also play a certain role in noise reduction.

[0029] To stably install the force transmission block 5, a slider 51 shaped like a "T" is fixedly connected to one side of the force transmission block 5 of the present application. The slider 51 is slidably inserted into the mounting rod 4. While ensuring the sliding installation of the force transmission block 5, the slider 51 can effectively prevent the force transmission block 5 from shaking.

[0030] To facilitate the installation of the force transmission block 5, a notch 43 for the force transmission block 5 to be slidably inserted is provided on one side of the mounting rod 4 of the present application. The notch 43 can facilitate the sliding insertion of the force transmission block 5 and also enable the force transmission block 5 to better contact the force transmission rod 7. A chute 44 for the slider 51 to be slidably inserted is communicated with one side of the notch 43, and the notch 43 can facilitate the sliding insertion of the slider 51.

[0031] To stably install the mounting plate 6, a plurality of telescopic rods 62 are fixedly connected between the mounting plate 6 and the mounting rod 4 of the present application. A first spring 63 is sleeved on the telescopic rod 62, which can prevent the mounting plate 6 from shaking when it is displaced and ensure that the mounting plate 6 only slides in the direction perpendicular to the mounting rod 4.

[0032] To further protect the first spring 63, a plurality of fourth rubber pads 64 are fixedly connected to one side of the mounting plate 6 in contact with the mounting rod 4. The fourth rubber pads 64 can play a certain buffering effect, thereby reducing the pressure borne by the first spring 63 and increasing the fatigue limit of the first spring 63, making the first spring 63 more durable. One side of the third rubber pad 61 in contact with the washing machine is set to be "arc-shaped", which can increase the contact area between the roller and the third rubber pad 61, thereby better buffering and reducing noise. A second spring 81 is fixedly connected between the first baffle 8 and the mounting rod 4. The second spring 81 can better push the first baffle 8 to reset, making it more convenient for the hydraulic oil to reset.

[0033] During actual implementation, the high-speed operation of the washing machine will cause the drum to shake. The shaking of the drum will first come into contact and collide with the third rubber pad 61, and then the mounting plate 6 will push the force transmission block 5 to slide, prompting the force transmission rod 7 to slide. The sliding of the force transmission rod 7 will push the first baffle 8 to slide, thereby pushing the hydraulic oil in the oil storage cavity 41 to flow into the installation cavity 42 through the diversion groove 48. The hydraulic oil flowing into the installation cavity 42 will push the second baffle 9 to slide, forcing the third spring 91 to compress. At the same time, the entire mounting rod 4 will also displace in the direction of the drum shaking, causing the second rubber pad 46, the cotton pad 47 to collide with the washing machine body. After the drum no longer applies pressure to the third rubber pad 61, the second baffle 9 will push the hydraulic oil to flow back into the oil storage cavity 41 through the diversion groove 48 under the action of the third spring 91, and the first baffle 8 will also reset under the push of the hydraulic oil and the second spring 81. When the first baffle 8 resets, it will push the force transmission rod 7 to slide, and the sliding force transmission rod 7 will also push the force transmission block 5 to slide back to its original position. Moreover, the mounting plate 6 will also slide back to its original position under the action of the first spring 63. When the mounting plate 6 slides, it will also drive the force transmission block 5 to reset. In this way, the viscous force of the hydraulic oil can be effectively exerted, and the impact force and vibration effect generated by the drum collision can be offset by the frictional force between the hydraulic oil and the mounting rod 4. Additionally, the noise generated by the collision can be greatly reduced through the first rubber pad 45, the second rubber pad 46, the cotton pad 47, the third rubber pad 61, and the fourth rubber pad 64.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
