Description
Technical Field
[0001] The present invention relates to the technical field related to furniture, and in particular to a piece of furniture with a buffer device. Background Art
[0002] Common furniture products with movable doors include kitchen cabinets, wardrobes, bookcases and storage cabinets. These furniture generally include a fixed cabinet body and a cabinet door that is rotatably connected to the cabinet body. The cabinet door may collide with the cabinet body when opening or closing. Especially when closing the door, the direct collision between the cabinet door and the cabinet body will make a loud noise, which not only produces household noise and affects the rest of other family members, but also easily causes damage to the cabinet door and the cabinet body at the contact point after long-term use. In order to reduce the impact caused by the contact between the door and the cabinet body, it becomes very necessary to install a buffer device in the furniture. By installing a buffer device between the movable door and the cabinet body, the noise generated by the collision between the movable door and the cabinet body when opening or closing can be effectively reduced, which is also conducive to protecting the furniture and thus extending the service life of the furniture.
[0003] Among them, the top rod type buffer device is a common buffer device on the market. For example, the Chinese utility model patent with the publication number CN219344429U discloses a cabinet door buffer, including a fixed tube, a connecting rod is inserted horizontally on the right side of the inside of the fixed tube, and a protective head is bolted to the right side of the connecting rod, and a supporting and protective buffer seat structure is arranged on the left side of the inside of the fixed tube; wherein the supporting and protective buffer seat structure includes a fastening rod connected to the fixed tube, and a buffer spring is also arranged between the fastening rod and the connecting rod. In this way, the cabinet door can be buffered and protected by the protective head and the contraction of the buffer spring. However, the connecting rod stroke of this buffer device is short, and it is only suitable for the cabinet door in the final stage of closing, and it only plays a role in reducing the closing sound. The rotation speed of the cabinet door during the closing process is uncontrolled. If the rotation speed is too fast, the cabinet door may rebound and open after colliding with the buffer device, so that the cabinet door hits the buffer device multiple times.
[0004] In order to solve the above problems, people have also designed another buffer device, such as the Chinese utility model patent with publication number CN217106621U, which discloses a gas support mechanism with bidirectional adjustable angle buffer, including: a support assembly, having a gas spring and a support seat, one end of the gas spring is hinged to the cabinet body, the other end of the gas spring is hinged to the support seat, the support seat is installed on the cabinet door, and the end of the gas spring is circumferentially provided with a first convex portion and a second convex portion in sequence; a buffer assembly, having a rotating member and a damping buffer, the rotating member and the damping buffer are arranged on the support seat, and the rotating member abuts against the damping buffer; when the cabinet door is closed, the first convex portion abuts against the rotating member and drives the rotating member to rotate, and the damping buffer prevents the rotating member from rotating; when the cabinet door is opened, the second convex portion abuts against the rotating member and drives the rotating member to rotate, and the damping buffer prevents the rotating member from rotating. The utility model can have a buffering effect when the cabinet door is opened and closed. However, this buffer structure is large in size and exposed to the outside, which not only occupies the storage space of the cabinet body, but also looks unsightly when the cabinet door is opened. Utility Model Content
[0005] In order to overcome at least one of the above problems existing in the prior art, the present invention proposes a furniture with a buffer device, comprising a cabinet body, a cabinet door and a first rotating shaft, wherein the first rotating shaft is arranged on the cabinet body or the cabinet door, and the cabinet door is rotatably connected to the front end opening of the cabinet body through the first rotating shaft; characterized in that it also includes a first buffer device, the first buffer device includes a first damper, an axis connection block, a first pressing block and a second rotating shaft, wherein the first damper is arranged on the cabinet body, the axis connection block is connected to the first rotating shaft and can rotate with the cabinet door, the first pressing block is arranged between the axis connection block and the first damper, and the first pressing block is rotatably connected to the axis connection block through the second rotating shaft, and the second rotating shaft is parallel to the first rotating shaft and arranged at intervals; the cabinet door can rotate forward with the axis connection block during closing, the axis connection block can move with the first pressing block so that the first pressing block is pressed against the first damper, the first damper can apply movement resistance to the first pressing block, and the first pressing block then slows down the rotation speed of the axis connection block and the cabinet door.
[0006] Among them, the cabinet body is the main component of the furniture, which includes a plurality of side walls fixedly connected together in a frame shape. In one embodiment, the cabinet body is arranged upright. According to the arrangement orientation, the side walls include an upper side wall, a lower side wall, a left side wall and a right side wall. The upper side wall, the lower side wall, the left side wall and the right side wall define a cabinet cavity. An opening is formed at the front end of the side wall, and items can be placed in the cabinet cavity through the opening.
[0007] The cabinet door is a movable component that cooperates with the cabinet body, and is mainly used to cover at least part of the opening at the front end of the cabinet body. The rotation arrangement of the cabinet door is also flexible. According to the different positions of the first rotating shaft, the cabinet door can be turned left or right or up and down. When the cabinet door is in a closed state, the cabinet door is arranged roughly vertically with the side wall of the cabinet body.
[0008] The first rotating shaft is a connecting member between the cabinet body and the cabinet door, that is, the cabinet body and the cabinet door are both connected to the first rotating shaft. However, the first rotating shaft being arranged on the cabinet body or the cabinet door has two meanings: one is that the first rotating shaft can be fixedly connected to the cabinet body or the cabinet door, and the first rotating shaft does not rotate relative to the fixedly connected member; the other is that the first rotating shaft is arranged on one of the cabinet body or the cabinet door in an alternative manner.
[0009] The first buffer device is a device used to slow down the rotation speed of the cabinet door during closing and to reduce the impact force when the cabinet door collides with the cabinet body.
[0010] Among them, the first damper is a component that can contact with the first push block and provide reverse movement resistance for the moving first push block. A general damper includes a damper housing and a push rod or gear movably connected to the damper housing. A spring or damping oil is arranged in the damper housing to hinder the speed of the push rod moving back and forth or the speed of the rotating gear rotating.
[0011] The shaft connection block has two connection relationships: one is a component that can rotate around the central axis of the first rotating shaft; the other is connected to the cabinet door and rotates with the cabinet door, so that the first top pressure block can be driven toward the first damper during the rotation of the cabinet door. In this way, according to the different fixed installation methods of the first rotating shaft, the shaft connection block has at least two installation states: the first state, in which the first rotating shaft is fixedly installed on the cabinet door, and the shaft connection block can rotate with the cabinet door and also rotate around the central axis of the first rotating shaft only by being fixedly connected to the first rotating shaft; the second state, in which the first rotating shaft is fixedly installed on the cabinet body, in which case the shaft connection block needs to be fixedly connected to the cabinet door and can be rotatably connected to the first rotating shaft.
[0012] The first pressing block is a component arranged between the shaft connection block and the first damper for contacting the first damper, and has at least two connection relationships. The first is that the first pressing block is connected to the shaft connection block by the second rotating shaft. Since the second rotating shaft is offset to one side of the first rotating shaft, when the shaft connection block rotates, the shaft connection block can drive the first pressing block to approach or move away from the first damper; the second is that the first pressing block can contact the first damper, especially when the first pressing block approaches and presses the first damper during the movement, as the two get closer and closer, the first damper continuously provides resistance to the first pressing block to slow down the closing speed of the cabinet door. Under the action of the shaft connection block and the first damper, the first pressing block will also rotate around the axis of the second rotating shaft during the movement, but this does not affect the overall movement of the first pressing block to press the first damper, but can allow the first push rod to slide smoothly along the inclined surface of the first pressing block. Of course, in a further technical solution, in order to limit the opening and closing angle of the first pressing block, a limiting pressing block is also provided on the first pressing block or the shaft connecting block, so that when the first pressing block rotates to a predetermined angle, the first pressing block and the shaft connecting block are connected together through the limiting pressing block and rotate synchronously together.
[0013] Among them, the shaft connecting block can move with the first pressing block and press against the first damper, which has the following two meanings: first, the first pressing block can be moved under the action of the shaft connecting block, and the first damper acts as an external component to affect the movement speed of the first pressing block; second, the connection relationship between the first pressing block and the first damper is not limited in the initial position of the cabinet door being closed. In one embodiment, during the closing process of the cabinet door, the first pressing block and the first damper are separated within an initial very short stroke, and the two are combined after this short stroke. In another embodiment, the first pressing block and the first damper remain in a combined state.
[0014] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are:
[0015] First, by connecting a movable first pressing block to the shaft connecting block in an offset manner, the first pressing block can be
[0016] The first pressing block can be translated and rotated. It does not need to rotate with the shaft connection block at a large angle. Instead, it can press the first damper by swinging within a small range through its own rotation. This arrangement not only reduces the size and swing space of the shaft connection block, but also makes the overall structure compact, occupies less space and has more flexible transmission.
[0017] Secondly, the first pressing block can also utilize the characteristic that the rotation angle of the first pressing block is smaller than the rotation angle of the shaft connection block. The first pressing block only needs to be provided with a smaller contact surface to achieve contact with the first damper to achieve a deceleration effect. This not only reduces the material usage of the first pressing block, but also ensures that the first pressing block and the first damper can maintain contact within a small range of rotation.
[0018] Third, the shaft connection block and the first damper are arranged on the cabinet door and the cabinet body respectively, and the first top pressure block is used as a connecting piece to convert the rotation of the shaft connection block into a translational linear motion, which is conducive to cooperating with the resistance output mode of the first damper to achieve a better deceleration effect;
[0019] Fourth, the first buffer device is arranged next to the first rotating shaft, which not only reduces the overall volume, but also makes it easy to control the first top pressure block and the first damper to touch each other throughout or most of the stroke, ensuring that the cabinet door can rotate slowly during most of the closing process, which not only provides a better user experience, but also greatly reduces the impact between the cabinet door and the cabinet body, which is beneficial to increasing the service life of the furniture.
[0020] A further technical solution may also include a cabinet baffle, which is provided on the cabinet body and arranged in front of the first damper. The first top pressure block is arranged between the first damper and the cabinet baffle, and can rotate in the opposite direction with the shaft connection block when the cabinet door is opened. The first top pressure block moves away from the first damper and approaches the cabinet baffle forward under the action of the shaft connection block and the first damper. When viewed from the front to the back, the cabinet baffle at least blocks the first damper and at least part of the first top pressure block, and can prevent the blocked part of the first top pressure block from moving forward beyond the cabinet baffle. The cabinet baffle has two functions. One is that when the cabinet door is opened, it can block at least part of the first damper and the first top pressure block, thereby improving the overall aesthetics of the furniture. The other is that the cabinet baffle can also be used to prevent the first top pressure block from moving too far forward, thereby reducing the interference between components and providing support and positioning for the first top pressure block.
[0021] Since the cabinet partition baffle is arranged in front of the first damper, in one embodiment, the top of the cabinet partition baffle is also partially arranged between the first damper and the shaft connection block. In order to avoid the cabinet partition baffle, the first pressure block is L-shaped, including a horizontal arm and a vertical arm, wherein one end of the horizontal arm is rotatably connected to the shaft connection block through the second rotating shaft, and the other end is connected to the vertical arm, and the vertical arm is arranged between the cabinet partition baffle and the first damper, and the vertical arm has a first pressure surface protruding outward in an arc shape on the side facing the first damper. The first pressure block arranged in this way forms a bent structure, which avoids the cabinet partition baffle well on the basis of satisfying the transmission function; in addition, by arranging the arc-shaped first pressure surface on the vertical arm, the top rod of the first damper can be slidably pressed against the first pressure surface.
[0022] The first buffer device is used to slow down the rotation speed of the cabinet door when it is closed. A further technical solution may be to further include a second buffer device, wherein the second buffer device includes a second damper and a second top pressure block, wherein the second damper is arranged on the cabinet body, and the second top pressure block is arranged on the cabinet door. The cabinet door can rotate in the opposite direction with the second top pressure block during the opening process, and the second top pressure block can touch the second damper during the rotation process. The second damper can apply rotation resistance to the second top pressure block, thereby slowing down the reverse rotation speed of the second top pressure block and the cabinet door. By combining the first buffer device with the second buffer device, the cabinet door can achieve deceleration when opening and closing, which greatly improves the user experience.
[0023] A further technical solution may be that the second cam-shaped pressing block has an arc-shaped second pressing surface on the side facing the second damper, and when the cabinet door is opened, the top rod of the second damper can press against the second pressing surface on the second pressing block and move away from the first rotating shaft along the second pressing surface. The second pressing surface is a part of the outwardly protruding surface of the second pressing block, which is used to cooperate with the top rod of the second damper. When viewed along the cross-sectional direction, the distance between each point on the second pressing surface and the first rotating shaft changes from near to far; the effect of such a setting is to allow the second pressing block to continuously press against the top rod of the second damper when rotating, so that the cabinet door can be continuously buffered by the second damper during the opening process.
[0024] A further technical solution may also include a door baffle plate disposed on the cabinet door, the door baffle plate being arranged on the inner side of the second top pressure block and extending toward one side of the cabinet body, and when the cabinet door is in a closed state, the free end of the door baffle plate and the free end of the cabinet baffle plate are close to each other. The advantage of such a setting is that a baffle layer can be formed on the connecting side of the cabinet door and the cabinet body, effectively blocking external dust.
[0025] A further technical solution may be that both the first damper and the second damper are telescopic dampers, and the first damper and the second damper are arranged obliquely on the side wall of the cabinet body, and the angle between the first damper, the second damper and the side wall of the cabinet body is 15°~45°. The oblique arrangement of the first damper and the second damper can allow the top rod to better cater to the rotating first top pressure block and the second top pressure block, allowing the two to be engaged together more quickly to achieve buffering of the cabinet door, thereby improving the user experience when the cabinet door is opened or closed.
[0026] In order to enable the cabinet door to be opened and closed automatically, a further technical solution may be that the first rotating shaft is fixedly connected to the upper part of the cabinet door, and an axis connecting arm is provided on the cabinet body, and the axis connecting arm can be rotatably connected to the first rotating shaft, so that the cabinet door can be turned down and rotated forward to close the door and turned up and rotated reversely to open the door; it also includes a counterweight block, which is connected to the upper end of the cabinet door, and the weight of the counterweight block is not greater than the weight of the cabinet door; when the cabinet door is in a closed state, the center of gravity of the cabinet door is located at the center of the first rotating shaft. On the front side of the axis, the position of the center of gravity of the counterweight block does not pass forward beyond the axis of the first rotating shaft; when the cabinet door rotates in the opposite direction under the action of external force, when the distance between the position of the center of gravity of the counterweight block and the axis of the first rotating shaft increases to a preset value, the cabinet door can automatically flip upward and open under the action of the counterweight block; on the contrary, when closing the cabinet door, when the cabinet door rotates forward under the action of external force, when the distance between the position of the center of gravity of the counterweight block and the axis of the first rotating shaft decreases to a preset value, the cabinet door can automatically flip downward and close under the action of the counterweight block.
[0027] A further technical solution may be that the first buffer device has at least two and is arranged at both ends of the first rotating shaft, and the second buffer device is arranged between the two first buffer devices.
[0028] Since the present invention has the above characteristics and advantages, it can be applied to furniture with buffer devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The structure of the modular cabinet using the technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0039] Except for those explicitly stated to be equivalent or alternative implementation schemes, the various implementation details disclosed below can be selectively applied or combined in one embodiment even if they are not directly related or synergistic in terms of functions.
[0040] like Figure 1 to Figure 9As shown, the present invention proposes a furniture with a buffer device, including a cabinet body 1, a cabinet door 2 and a first rotating shaft 3, wherein the first rotating shaft 3 is arranged on the cabinet body 1 or the cabinet door 2, and the cabinet door 2 is rotatably connected to the front end opening of the cabinet body 1 through the first rotating shaft 3. The cabinet body 1 is the main component of the furniture, and includes a plurality of side walls fixedly connected together in a frame shape. In this embodiment, the cabinet body 1 is arranged vertically. According to the arrangement orientation, the side walls include an upper side wall 11, a lower side wall 12, a left side wall 13 and a right side wall 14. The upper side wall 11, the lower side wall 12, the left side wall 13 and the right side wall 14 define a cabinet cavity 10, and an opening is formed at the front end of the side wall, through which objects can be placed in the cabinet cavity 10. The cabinet door 2 is a movable component that cooperates with the cabinet body 1, and is mainly used to cover at least part of the opening at the front end of the cabinet body 1. In this embodiment, the first rotating shaft 3 is fixedly connected to the upper part of the cabinet door 2, and the cabinet body 1 is provided with an axis connecting arm 15, and the axis connecting arm 15 can be rotatably connected to the first rotating shaft 3, so that the cabinet door 2 can be turned down to rotate forward to close the door and turned up to rotate backward to open the door. Of course, in other equivalent implementations, the cabinet door 2 can also be turned left and right.
[0041] In order to allow the cabinet door 2 to achieve buffering when closing, it also includes a first buffer device 4, which includes a first damper 41, an axis connecting block 42, a first pressing block 43 and a second rotating shaft 44, wherein the first damper 41 is arranged on the cabinet body 1, the axis connecting block 42 is connected to the first rotating shaft 3 and can rotate with the cabinet door 2, the first pressing block 43 is arranged between the axis connecting block 42 and the first damper 41, and the first pressing block 43 is rotatably connected to the axis connecting block 42 through the second rotating shaft 44, and the second rotating shaft 44 is parallel to the first rotating shaft 3 and arranged at intervals; the cabinet door 2 can rotate forward with the axis connecting block 42 during the closing process, the axis connecting block 42 can move with the first pressing block 43 so that the first pressing block 43 is pressed against the first damper 41, and the first damper 41 can apply movement resistance to the first pressing block 43, and the first pressing block 43 then slows down the rotation speed of the axis connecting block 42 and the cabinet door 2.
[0042] In this embodiment, the first damper 41 is a member capable of contacting the first pressing block 43 and providing reverse movement resistance to the moving first pressing block 43. Figure 3As shown, the first damper 41 is a telescopic damper, which includes a first damper housing 411 and a first push rod 412 movably connected to the first damper housing 411. A spring or damping oil is also provided in the first damper housing 411 to hinder the speed of the push rod moving back and forth.
[0043] like Figure 3 As shown, the shaft connection block 42 is fixed to the first rotating shaft 3 by screws. Since the first rotating shaft 3 and the cabinet door 2 rotate synchronously, the shaft connection block 42 also rotates synchronously with the first rotating shaft 3 and the cabinet door 2. A protruding connection block is also provided on the shaft connection block 42. A shaft hole for installing the second rotating shaft 44 is provided on the connection block. The second rotating shaft 44 is installed in the shaft hole and forms a parallel and offset structure with the first rotating shaft 3. When the first pressing block 43 is connected to the shaft connection block 42 through the second rotating shaft 44, when the shaft connection block 42 rotates, the first pressing block 43 is driven to move toward the first damper 41, and the first pressing block 43 can also rotate around the axis of the second rotating shaft 44.
[0044] The first pressing block 43 is a component arranged between the shaft connection block 42 and the first damper 41 for contacting the first damper 41, and has at least two connection relationships. The first is that the first pressing block 43 is rotatably connected to the shaft connection block 42 through the second rotating shaft 44. Since the second rotating shaft 44 is offset to one side of the first rotating shaft 3, when the shaft connection block 42 rotates, the shaft connection block 42 can drive the first pressing block 43 to approach or move away from the first damper 41. The second is that the first pressing block 43 can contact the first damper 41, especially when the first pressing block 43 approaches and presses against the first damper 41 during the movement, as the two get closer and closer, the first damper 41 continuously provides resistance to the first pressing block 43 to slow down the closing speed of the cabinet door 2. Under the action of the shaft connection block 42 and the first damper 41, the first push block 43 will also rotate around the axis of the second rotating shaft 44 during the movement, but this does not affect the overall movement of the first push block 43 toward and against the first damper 41, but can allow the first push rod 412 to slide smoothly along the inclined surface of the first push block 43. Of course, in a further technical solution, in order to limit the opening and closing angle of the first push block 43, a limiting push block is further provided on the first push block 43 or the shaft connection block 42, so that when the first push block 43 rotates to a predetermined angle, the first push block 43 and the shaft connection block 42 are connected together through the limiting push block so as to rotate synchronously together.
[0045] It can be seen from the above connection structure that by connecting the movable first pressing block 43 to the shaft connection block 42 in an offset manner, the first pressing block 43 can be both translated and rotated. The first pressing block 43 does not need to rotate a large angle with the shaft connection block 42, but can achieve the pressing of the first damper 41 by swinging within a small range through its own rotation. This arrangement not only reduces the size and swinging space of the shaft connection block 42, but also has a compact overall structure, occupies less space and is flexible in transmission. It can also take advantage of the fact that the rotation angle of the first pressing block 43 is smaller than the rotation angle of the shaft connection block 42. The first pressing block 43 only needs to set a smaller contact surface to achieve contact with the first damper 41 to achieve a deceleration effect. This not only reduces the material consumption of the first pressing block 43, but also ensures that the first pressing block 43 and the first damper 41 can maintain contact within a small range of rotation.
[0046] Furthermore, the shaft connecting block 42 and the first damper 41 are respectively arranged on the cabinet door 2 and the cabinet body 1, and the first top pressure block 43 is used as a connecting piece to convert the rotation of the shaft connecting block 42 into a translational linear motion, which is beneficial to cooperate with the resistance output mode of the first damper 41 to achieve a better deceleration effect; the first buffer device 4 is arranged next to the first rotating shaft 3, not only the overall volume is reduced, but also it is easy to control the first top pressure block 43 and the first damper 41 to maintain contact throughout or most of the stroke, ensuring that the cabinet door 2 can achieve slow rotation during most of the closing process, which not only provides a better user experience, but also can greatly reduce the impact between the cabinet door 2 and the cabinet body 1, which is beneficial to improving the service life of the furniture.
[0047] A further technical solution may also include a cabinet partition baffle 61, which is arranged on the upper side wall 11 of the cabinet body 1 and arranged in front of the first damper 41. The first top pressure block 43 is arranged between the first damper 41 and the cabinet partition baffle 61. When the cabinet door 2 is opened, it can rotate in the opposite direction with the shaft connecting block 42. Under the action of the shaft connecting block 42 and the first damper 41, the first top pressure block 43 moves away from the first damper 41 and moves forward to the cabinet partition baffle 61. Looking from front to back, the cabinet partition baffle 61 at least blocks the first damper 41 and at least part of the first top pressure block 43, and can prevent the blocked part of the first top pressure block 43 from moving forward beyond the cabinet partition baffle 61. The cabinet partition baffle 61 has two functions. First, when the cabinet door 2 is opened, it can cover at least part of the first damper 41 and the first top pressure block 43, thereby improving the overall aesthetics of the furniture. Second, the cabinet partition baffle 61 can be used to prevent the first top pressure block 43 from moving too far forward, thereby reducing interference between components and providing support and positioning for the first top pressure block 43.
[0048] Since the cabinet partition baffle 61 is arranged in front of the first damper 41, in one embodiment, the top of the cabinet partition baffle 61 is also partially arranged between the first damper 41 and the shaft connecting block 42. In order to avoid the cabinet partition baffle 61, the first top pressure block 43 is L-shaped, including a horizontal arm 431 and a vertical arm 432, wherein one end of the horizontal arm 431 is rotatably connected to the shaft connecting block 42 through the second rotating shaft 44, and the other end is connected to the vertical arm 432. The vertical arm 432 is arranged between the cabinet partition baffle 61 and the first damper 41, and the vertical arm 432 has a first pressing surface 433 protruding outward in an arc shape on the side facing the first damper 41. The first pressing block 43 arranged in this way forms a bent structure, which can avoid the cabinet partition baffle 61 while satisfying the transmission function; in addition, by setting the arc-shaped first pressing surface 433 on the vertical arm 432, the top rod of the first damper 41 can be slidably pressed against the first pressing surface 433.
[0049] The first buffer device 4 is used to slow down the rotation speed of the cabinet door 2 when closing. A further technical solution may be to further include a second buffer device 5, wherein the second buffer device 5 includes a second damper 51 and a second top pressure block 52. The second damper 51 is arranged on the upper side wall 11 of the cabinet body 1, and the second top pressure block 52 is arranged on the cabinet door 2. The cabinet door 2 can rotate in the opposite direction with the second top pressure block 52 during the opening process. The second top pressure block 52 can touch the second damper 51 during the rotation process. The second damper 51 can apply rotation resistance to the second top pressure block 52, thereby slowing down the speed of the second top pressure block 52 and the cabinet door 2 rotating in the opposite direction to open the door. By combining the first buffer device 4 with the second buffer device 5, the cabinet door 2 can achieve deceleration when opening and closing, which greatly improves the user experience. Furthermore, the first buffer device 4 has at least two and is arranged at both ends of the first rotating shaft 3, and the second buffer device 5 is arranged between the two first buffer devices 4. The advantage of such an arrangement is that when the cabinet door 2 is opened, a buffering force is provided to the cabinet door 2 at a position close to the middle of the cabinet door 2, thereby reducing deformation and shaking of the middle of the cabinet door 2.
[0050] A further technical solution may be that the second cam-shaped pressing block 52 has an arc-shaped second pressing surface 521 on the side facing the second damper 51, and during the opening process of the cabinet door 2, the push rod of the second damper 51 can press against the second pressing surface 521 on the second pressing block 52 and move away from the first rotating shaft 3 along the second pressing surface 521. The second pressing surface 521 is a part of the second pressing block 52 that protrudes outward, and the surface is used to cooperate with the push rod of the second damper 51. When viewed along the cross-sectional direction, the distance between each point on the second pressing surface 521 and the first rotating shaft 3 changes from near to far; the effect of such a setting is that the second pressing block 52 can continuously press against the push rod of the second damper 51 when rotating, so that the cabinet door 2 can be continuously buffered and blocked by the second damper 51 during the opening process.
[0051] A further technical solution may also include a door baffle plate 62 disposed on the cabinet door 2, the door baffle plate 62 being arranged on the inner side of the second top pressure block 52 and extending toward one side of the cabinet body 1, and when the cabinet door 2 is in a closed state, the free end of the door baffle plate 62 and the free end of the cabinet baffle plate 61 are close to each other. The advantage of such a setting is that a baffle layer is formed on the connecting side of the cabinet door 2 and the cabinet body 1, effectively blocking external dust.
[0052] A further technical solution may be that both the first damper 41 and the second damper 51 are telescopic dampers, and the first damper 41 and the second damper 51 are arranged obliquely on the side wall of the cabinet body 1, and the angle between the first damper 41 and the second damper 51 and the side wall of the cabinet body 1 is 15°~45°. The oblique arrangement of the first damper 41 and the second damper 51 can allow the push rod to better accommodate the rotating first top pressure block 43 and the second top pressure block 52, allowing the two to be engaged together more quickly to achieve buffering of the cabinet door 2, thereby improving the user experience when the cabinet door 2 is opened or closed.
[0053] In order to enable the cabinet door 2 to be opened and closed automatically, a further technical solution may also be that it further includes a counterweight block 7, which is connected to the upper end of the cabinet door 2, and the weight of the counterweight block 7 is not greater than the weight of the cabinet door 2; when the cabinet door 2 is in a closed state, the center of gravity of the cabinet door 2 is located in front of the axis of the first rotating shaft 3, and the position of the center of gravity of the counterweight block 7 does not move forward beyond the axis of the first rotating shaft 3; when the cabinet door 2 rotates in the opposite direction under the action of an external force, when the distance between the position of the center of gravity of the counterweight block 7 and the axis of the first rotating shaft 3 increases to a preset value, the cabinet door 2 can automatically flip upward and open under the action of the counterweight block 7; on the contrary, when closing the cabinet door 2, when the cabinet door 2 rotates forward under the action of an external force, when the distance between the position of the center of gravity of the counterweight block 7 and the axis of the first rotating shaft 3 decreases to a preset value, the cabinet door 2 can automatically flip downward and close under the action of the counterweight block 7. Furthermore, in order to reduce the collision between the counterweight block 7 and the cabinet body 1 , a buffer rubber is also provided on the side of the counterweight block 7 or the cabinet body 1 .
