[0028] The preferred embodiments of the utility model will be described below in conjunction with the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model, and are not intended to limit the protection scope of the utility model.
[0029] It should be noted that in the description of the utility model, the terms "upper", "lower", "left", "right", "inner", "outer" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0030] In addition, it should be noted that in the description of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connection" should be broadly understood, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0031] The utility model provides a kind of furniture with damping structure, wherein furniture can be wardrobe, storage cabinet and other furniture capable of setting push-pull door. The furniture includes push-pull door, side wall, bottom plate and top plate, and track is arranged on the bottom plate and the top plate, and pulley is arranged on the top and bottom of push-pull door, and pulley is slidably connected with track to realize the sliding of push-pull door relative to top plate and bottom plate.
[0032] As shown in Figure 1 and Figure 2 , the end of the side edge of the push-pull door 1 is provided with a groove 11, and the damper 2 is arranged in the groove 11. A limiting assembly 6 is arranged on the side plate, and the limiting assembly 6 is at the same height as the damper 2 and corresponds to the damper 2. When the push-pull door 1 slides to the vicinity of the side plate, the damper 2 contacts the limiting assembly 6, and the damper 2 absorbs part of the kinetic energy of the push-pull door 1, thereby reducing the impact force of the side plate on the push-pull door 1. The smaller the impact force of the side plate on the push-pull door 1, the less likely the cooperation between the push-pull door 1 and the track is affected, and the probability of failure of the push-pull door 1 is also smaller, which helps to improve the service life of the furniture.
[0033] As shown in Figure 2 , in the utility model, the limiting assembly 6 includes a contact piece 61, a fixing piece 62 and an elastic piece 63. The fixing piece 62 is fixed to the side plate, the contact piece 61 is slidably connected with the fixing piece 62 along the moving direction of the push-pull door 1, and the elastic piece 63 is located between the contact piece 61 and the fixing piece 62. During the process of the push-pull door 1 impacting the limiting assembly 6, the elastic piece 63 can absorb part of the energy to reduce the impact force of the impact on the push-pull door 1. Then, the elastic piece 63 can release the absorbed elastic force to push the push-pull door 1 to rebound for a distance.
[0034] AsFigure 1 As shown, the damper 2 comprises a shell 21, a piston 22, a piston rod 23 and a return spring 24, the shell 21 is provided with a main cavity 211 and a communication cavity 212, the two ends of the communication cavity 212 are communicated with the two ends of the main cavity 211 respectively, the piston 22 is located in the main cavity 211 and is in sliding sealing with the main cavity 211, one end of the piston rod 23 is fixed to the piston 22 and the other end extends out of the shell 21 and is in sliding sealing with the shell 21, the return spring 24 is located in the main cavity 211 and is located on the side of the piston 22 away from the piston rod 23, and the two ends of the return spring 24 are respectively in abutment with the end of the main cavity 211 and the piston 22. In order to facilitate description, the main cavity 211 located on the side of the piston 22 away from the piston rod 23 is defined as a first cavity, and the remaining main cavity 211 is defined as a second cavity, and the communication cavity 212 is used to communicate the first cavity and the second cavity. The diameter of the communication cavity 212 is generally smaller than the diameter of the main cavity 211, so as to increase the damping of the medium in the first cavity and the second cavity flowing through the communication cavity 212.
[0035] During the process that the sliding door 1 hits the limiting assembly 6, the free end of the piston rod 23 first contacts the limiting assembly 6, pushes the piston rod 23 and the piston 22 to move in the main cavity 211, pushes the medium in the first cavity to the second cavity through the communication cavity 212 to absorb the kinetic energy of the sliding door 1, and at the same time, the return spring 24 is also compressed to absorb the kinetic energy of the sliding door 1, so as to reduce the impact force of the limiting assembly 6 on the sliding door 1. After the sliding door 1 is separated from the limiting assembly 6, the piston 22 is pushed to move to the direction of the limiting assembly 6 under the elastic force of the return spring 24, and in the process, the resistance required for moving the medium in the second cavity to the first cavity through the communication cavity 212 needs to be overcome, so as to absorb the elastic potential energy of the return spring 24.
[0036] The medium filled in the main cavity 211 can be gas or liquid, and in the example of the utility model, the medium is hydraulic oil, so as to increase the damping of the medium flowing through the communication cavity 212.
[0037] In addition, an adjusting bolt can also be arranged on the shell, the adjusting bolt is in threaded connection with the shell and is inserted into the communication cavity 212, and by changing the depth of the adjusting bolt inserted into the communication cavity 212, the damping of the medium flowing in the communication cavity 212 can be changed.
[0038] The side of the contact piece 61 away from the fixing piece 62 and the free end of the piston rod 23 are both provided with a buffer pad, the buffer pad can absorb part of the impact energy, reduce the impact force of the impact on the sliding door 1, and also can play a role in noise reduction.
[0039] In addition, the end of the side of the sliding door 1 is provided with a damping spring 3 and a guide rod 4, one end of the guide rod 4 is fixed to the sliding door 1, the damper 2 is in sliding connection with the guide rod 4, the damping spring 3 is sleeved on the guide rod 4 and abuts against the damper 2 and the sliding door 1 at both ends. Wherein, the free end of the guide rod 4 can be provided with a detachable blocking piece to limit the damper 2 from disengaging from the guide rod 4. In the process of the sliding door 1 impacting the limiting assembly 6, the damper 2 can move along the guide rod 4 to compress the damping spring 3, and convert part of the kinetic energy of the sliding door 1 into elastic potential energy of the damping spring 3, so as to reduce the impact force of the sliding door 1. In addition, the damping spring 3 can exert force on the damper 2 in the process of compression and reset, prolonging the action time of the damper 2 and continuously absorbing energy by the damper 2. Especially in the reset process of the damping spring 3, the damper 2 can also absorb part of the elastic potential energy of the damping spring 3, reducing the rebounding distance of the sliding door 1 after the reset of the damping spring 3, and improving the user experience.
[0040] In summary, the working principle of the furniture with the damping structure is as follows:
[0041] In the first stage, the sliding door 1 moves towards the limiting assembly 6, the free end of the piston rod 23 contacts the contact piece 61, and then the elastic piece 63 and the damping spring 3 are compressed to absorb the kinetic energy of the sliding door 1; at the same time, the impact force drives the piston rod 23 and the piston 22 to move in the main cavity 211, and drives the medium in the first cavity to the second cavity through the communication cavity 212 to absorb the kinetic energy of the sliding door 1. The above two processes are carried out at the same time to reduce the kinetic energy of the sliding door 1, thereby reducing the impact force of the sliding door 1 impacting the limiting assembly 6.
[0042] In the second stage, the sliding door 1 rebounds towards the direction away from the limiting assembly 6 under the action of the reaction force (mainly the elastic force of the elastic piece 63 and the damping spring 3), and in the process, the piston rod 23 and the piston 22 are driven to move in the main cavity 211, and the medium in the first cavity is driven to the second cavity through the communication cavity 212 to absorb the elastic potential energy of the damping spring 3 and the elastic piece 63, thereby reducing the rebounding distance of the sliding door 1 and improving the user experience.
[0043] In the third stage, the sliding door 1 is disengaged from the limiting assembly 6, and the piston 22 is driven to move towards the limiting assembly 6 under the elastic force of the reset spring 24, and in the process, the resistance required for moving the medium in the second cavity to the first cavity through the communication cavity 212 needs to be overcome, thereby absorbing the elastic potential energy of the reset spring 24.
[0044] The technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but the person skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. The person skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
