Description

Technical Field

[0001] This invention relates to the field of furniture technology, and in particular to a piece of furniture with a cushioning device. Background Technology

[0002] Common furniture products with sliding doors include kitchen cabinets, wardrobes, bookcases, and storage cabinets. These pieces typically consist of a fixed cabinet body and rotating doors connected to it. The doors may collide with the cabinet body when opening and closing, especially when closing, where the direct impact can produce significant noise. This not only disturbs other family members but also increases the risk of damage to the contact points over time. Therefore, installing cushioning devices in the furniture is essential to reduce the impact of the doors colliding with the cabinet body. By installing cushioning devices between the sliding doors and the cabinet body, the noise generated by the collision can be effectively reduced, protecting the furniture and extending its lifespan.

[0003] One common type of buffer device on the market is the top-rod type. For example, Chinese utility model patent CN219344429U discloses a cabinet door buffer, which includes a fixed tube. A connecting rod is horizontally inserted into the right side of the fixed tube, and a protective head is bolted to the right side of the connecting rod. A supporting protective buffer seat structure is provided on the left side of the fixed tube. The supporting protective buffer seat structure includes a fastening rod connected to the fixed tube, and a buffer spring is provided between the fastening rod and the connecting rod. In this way, the protective head and the contraction of the buffer spring can provide buffer protection for the cabinet door. However, the connecting rod stroke of this buffer device is relatively short, and it is only suitable for the final stage of closing the cabinet door. It only serves to reduce 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 again after colliding with the buffer device, causing the cabinet door to hit the buffer device multiple times.

[0004] To address the aforementioned problems, another type of buffer device has been designed. For example, Chinese utility model patent CN217106621U discloses a bidirectional adjustable angle buffer gas spring mechanism, comprising: a support assembly with a gas spring and a support base; one end of the gas spring is hinged to the cabinet body, and the other end is hinged to the support base; the support base is mounted on the cabinet door; and the gas spring end has a first protrusion and a second protrusion arranged circumferentially; and a buffer assembly with a rotating member and a damping buffer; the rotating member and the damping buffer are disposed on the support base, and the rotating member abuts against the damping buffer; when the cabinet door is closed, the first protrusion abuts against the rotating member and drives the rotating member to rotate, while the damping buffer prevents the rotating member from rotating; when the cabinet door is open, the second protrusion abuts against the rotating member and drives the rotating member to rotate, while the damping buffer prevents the rotating member from rotating. This utility model provides buffering during both opening and closing of the cabinet door. However, this type of buffer structure is large and exposed, which not only takes up storage space in the main body of the cabinet, but is also very unsightly when the cabinet door is opened. Summary of the Invention

[0005] To overcome at least one of the aforementioned problems in the prior art, the present invention proposes a furniture with a buffer device, comprising a cabinet body, a cabinet door, and a first pivot. The first pivot is disposed on the cabinet body or the cabinet door, and the cabinet door is rotatably connected to the front opening of the cabinet body via the first pivot. The invention is characterized by further comprising a first buffer device, which includes a first damper, a shaft connecting block, a first pressing block, and a second pivot. The first damper is disposed on the cabinet body, the shaft connecting block is connected to the first pivot and can rotate with the cabinet door, the first pressing block is arranged between the shaft connecting block and the first damper, and the first pressing block is rotatably connected to the shaft connecting block via the second pivot. The second pivot is parallel to and spaced apart from the first pivot. During closing, the cabinet door can rotate forward with the shaft connecting block, and the shaft connecting block can move the first pressing block, causing the first pressing block to press against the first damper. The first damper applies resistance to the movement of the first pressing block, thereby slowing down the rotation speed of the shaft connecting block and the cabinet door.

[0006] The cabinet body is the main component of the furniture, which includes several frame-shaped side walls that are fixedly connected together. In one embodiment, the cabinet body is arranged vertically. Depending on the arrangement, 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, lower side wall, left side wall, and right side wall define the cabinet cavity. The front end of the side wall forms an opening through which items can be placed into the cabinet cavity.

[0007] The cabinet door is a movable component that works in conjunction with the main body of the cabinet, primarily used to cover at least part of the opening at the front of the main body. The cabinet door's rotation arrangement is flexible; depending on the position of the first pivot, the cabinet door can flip left, right, or up and down. When the cabinet door is closed, it is approximately perpendicular to the side wall of the main body.

[0008] The first pivot is a connecting component between the cabinet body and the cabinet door; that is, both the cabinet body and the cabinet door are connected to the first pivot. However, the first pivot being located on either the cabinet body or the cabinet door has two meanings: firstly, the first pivot can be fixedly connected to the cabinet body or the cabinet door, and the first pivot does not rotate relative to the fixedly connected component; secondly, the first pivot can be selectively arranged on either the cabinet body or the cabinet door.

[0009] The first buffer device is used to reduce the rotation speed of the cabinet door during the closing process and to reduce the impact force when the cabinet door collides with the cabinet body.

[0010] The first damper is a component that can contact the first pressing block and provide reverse resistance to the moving first pressing block. A typical damper includes a damper housing and a push rod or gear movably connected to the damper housing. A spring or damping oil is provided in the damper housing to impede the speed of the push rod moving back and forth or the speed of the gear rotating.

[0011] The shaft connecting block has two connections: firstly, it is a component that can rotate around the central axis of the first rotating shaft; secondly, it is connected to the cabinet door and rotates with the cabinet door. This allows the first pressing block to move towards the first damper during the rotation of the cabinet door. Thus, depending on the fixing method of the first rotating shaft, the shaft connecting block has at least two installation states: firstly, the first rotating shaft is fixedly installed on the cabinet door, and the shaft connecting block only needs to be fixedly connected to the first rotating shaft to rotate with the cabinet door and also rotate around the central axis of the first rotating shaft; secondly, the first rotating shaft is fixedly installed on the cabinet body, in which case the shaft connecting block needs to be fixedly connected to the cabinet door while also being rotatably connected to the first rotating shaft.

[0012] The first pressing block is a component arranged between the shaft connecting block and the first damper for contacting the first damper. It has at least two connection relationships: first, it is rotatably connected to the shaft connecting block via the second rotating shaft. Since the second rotating shaft is offset to one side of the first rotating shaft, when the shaft connecting block rotates, it can move the first pressing block closer to or away from the first damper; second, the first pressing block can contact the first damper, especially when it moves closer to and presses against the first damper. As they get closer, the first damper continuously provides resistance to the first pressing block to slow down the closing speed of the cabinet door. Under the combined action of the shaft connecting block and the first damper, the first pressing block will also rotate around the axis of the second rotating shaft during movement. However, this does not affect the overall movement of the first pressing block towards and pressing against the first damper; instead, it allows 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 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 block and thus rotate together synchronously.

[0013] The shaft connecting block, capable of moving the first pressing block and pressing against the first damper, has two implications: first, the first pressing block can move under the action of the shaft connecting block, and the first damper acts as an external component, affecting the speed of movement of the first pressing block; second, the initial position of the cabinet door when closed does not define the connection between the first pressing block and the first damper. In one embodiment, during the cabinet door closing process, the first pressing block and the first damper are separated for a very short initial stroke, and then reconnect after this short stroke. In another embodiment, the first pressing block and the first damper remain connected throughout the process.

[0014] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: First, by connecting a movable first pressing block to the shaft connecting block in an offset manner, the first pressing block can both translate and rotate. The first pressing block does not need to rotate with the shaft connecting block at a large angle, but can achieve the pressure on the first damper by swinging within a small range through its own rotation. This setting not only reduces the size of the shaft connecting block and the swing space, but also makes the overall structure compact, occupies less space, and makes the transmission more flexible. Secondly, by taking advantage of the fact that the rotation angle of the first pressure block is smaller than that of the shaft connecting block, the first pressure block only needs to be set with a small contact surface to make contact with the first damper and achieve a deceleration effect. This not only reduces the amount of material used in the first pressure block, but also ensures that the first pressure block and the first damper can maintain contact within a small range of rotation. Third, the shaft connecting block and the first damper are respectively arranged on the cabinet door and the cabinet body. The rotation of the shaft connecting block is converted into a linear translation by the first top pressing block as a connecting member. This is beneficial to cooperate with the resistance output mode of the first damper to achieve a better deceleration effect. Fourth, the first buffer device is arranged next to the first rotating shaft, which not only reduces the overall size, but also makes it easy to control the first top pressure block and the first damper to contact each other throughout or most of the stroke, ensuring that the cabinet door can rotate slowly during most of the closing process. This not only provides a better user experience, but also greatly reduces the impact between the cabinet door and the cabinet body, which helps to improve the service life of the furniture.

[0015] A further technical solution could include a cabinet partition, which is disposed on the cabinet body and positioned in front of the first damper. The first pressing block is positioned between the first damper and the cabinet partition. When the cabinet door is opened, it can cause the shaft connecting block to rotate in the opposite direction. Under the action of the shaft connecting block and the first damper, the first pressing block moves away from the first damper and forward towards the cabinet partition. Viewed from front to back, the cabinet partition at least covers the first damper and at least part of the first pressing block, and prevents the covered portion of the first pressing block from moving forward beyond the cabinet partition. The cabinet partition serves two purposes: firstly, it covers at least part of the first damper and the first pressing block when the cabinet door is open, improving the overall aesthetics of the furniture; secondly, it prevents the first pressing block from moving excessively forward, reducing interference between components and providing support and positioning for the first pressing block.

[0016] Since the cabinet partition is positioned in front of the first damper, in one embodiment, the top of the cabinet partition is also partially positioned between the first damper and the shaft connecting block. To avoid the cabinet partition, the first pressing block is L-shaped, including a horizontal arm and a vertical arm. One end of the horizontal arm is rotatably connected to the shaft connecting block via the second pivot, and the other end is connected to the vertical arm. The vertical arm is positioned between the cabinet partition and the first damper, and the vertical arm has an outwardly protruding, arc-shaped first pressing surface on the side facing the first damper. This configuration of the first pressing block forms a bend, effectively avoiding the cabinet partition while fulfilling the transmission function. Furthermore, by providing the arc-shaped first pressing surface on the vertical arm, the top rod of the first damper can slidably press against the first pressing surface.

[0017] The first buffer device is used to slow down the rotational speed of the cabinet door when it closes. A further technical solution may include a second buffer device, which comprises a second damper and a second pressure block. The second damper is disposed on the cabinet body, and the second pressure block is disposed on the cabinet door. During opening, the cabinet door can rotate in the opposite direction along with the second pressure block. During rotation, the second pressure block can contact the second damper, which applies rotational resistance to the second pressure block, thereby slowing down the reverse rotational speed of both the second pressure block and the cabinet door. By combining the first and second buffer devices, the cabinet door can be decelerated during both opening and closing, greatly improving the user experience.

[0018] A further technical solution could be that the cam-shaped second pressing block has an arc-shaped second pressing surface on the side facing the second damper. During the opening of the cabinet door, 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 portion of the outwardly protruding surface of the second pressing block, which cooperates with the top rod of the second damper. Viewed in cross-section, the distance between points on the second pressing surface and the first rotating shaft varies from near to far. This arrangement ensures that the second pressing block continuously presses against the top rod of the second damper as it rotates, thus providing continuous buffering resistance to the cabinet door during opening.

[0019] A further technical solution could include a door partition plate disposed on the cabinet door. The door partition plate is arranged inside the second top pressing block and extends towards the cabinet body. When the cabinet door is closed, the free ends of the door partition plate and the free ends of the cabinet partition plate are close to each other. The advantage of this arrangement is that it forms a barrier layer on the connection side between the cabinet door and the cabinet body, effectively blocking external dust.

[0020] A further technical solution could be that both the first and second dampers are telescopic dampers, and the first and second dampers are inclinedly arranged on the side wall of the cabinet body, with the angle between the first and second dampers and the side wall of the cabinet body being 15° to 45°. The inclined arrangement of the first and second dampers allows the top rod to better meet the rotating first and second top pressure blocks, enabling them to engage more quickly and buffer the cabinet door, thus improving the user experience when opening or closing the cabinet door.

[0021] To enable the cabinet door to open and close automatically, a further technical solution is that the first rotating shaft is fixedly connected to the upper part of the cabinet door, and a connecting arm is provided on the cabinet body. The connecting arm is rotatably connected to the first rotating shaft, allowing the cabinet door to close by tilting down and open by tilting up and turning in the opposite direction. A counterweight is also included, connected to the upper end of the cabinet door, and the weight of the counterweight is not greater than the weight of the cabinet door. When the cabinet door is closed, the center of gravity of the cabinet door is located on the axis of the first rotating shaft. On the front side of the counterweight, the center of gravity of the counterweight does not extend forward beyond the axis of the first rotating shaft. When the cabinet door rotates in the opposite direction under the action of external force, the distance between the center of gravity of the counterweight and the axis of the first rotating shaft increases to a preset value, and the cabinet door can automatically flip upward and open under the action of the counterweight. Conversely, when closing the cabinet door, when the cabinet door rotates in the forward direction under the action of external force, the distance between the center of gravity of the counterweight and the axis of the first rotating shaft decreases to a preset value, and the cabinet door can automatically flip downward and close under the action of the counterweight.

[0022] A further technical solution could be that at least two first buffer devices are arranged at both ends of the first rotating shaft, and the second buffer device is arranged between the two first buffer devices.

[0023] Because of the above-mentioned features and advantages, this invention can be applied to furniture with cushioning devices. Attached Figure Description

Detailed Implementation

[0025] The structure of the modular cabinet applying the technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0026] Except where explicitly stated that they are equivalent or alternative implementation schemes, the various implementation details disclosed below may be selectively applied or combined in one embodiment even if they are not directly related or synergistic in terms of function.

[0027] like Figures 1-9As shown, this invention proposes a furniture with a buffer device, including a cabinet body 1, a cabinet door 2, and a first pivot 3. The first pivot 3 is disposed on the cabinet body 1 or the cabinet door 2, and the cabinet door 2 is rotatably connected to the front opening of the cabinet body 1 via the first pivot 3. The cabinet body 1 is the main component of the furniture, comprising several frame-like sidewalls fixedly connected together. In this embodiment, the cabinet body 1 is vertically arranged. Depending on its orientation, the sidewalls include an upper sidewall 11, a lower sidewall 12, a left sidewall 13, and a right sidewall 14. The upper sidewall 11, lower sidewall 12, left sidewall 13, and right sidewall 14 define a cabinet cavity 10. The front end of each sidewall forms an opening through which items can be placed into the cabinet cavity 10. The cabinet door 2 is a movable component that cooperates with the cabinet body 1, mainly used to cover at least part of the front opening 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 a connecting arm 15 is provided on the cabinet body 1. The connecting arm 15 is rotatably connected to the first rotating shaft 3, thereby allowing the cabinet door 2 to achieve downward rotation for closing and upward rotation for opening. Of course, in other equivalent embodiments, the cabinet door 2 can also achieve left and right flipping.

[0028] To enable the cabinet door 2 to achieve a buffering effect when closed, a first buffering device 4 is also included. The first buffering device 4 includes a first damper 41, a shaft connecting block 42, a first pressing block 43, and a second rotating shaft 44. The first damper 41 is disposed on the cabinet body 1. The shaft 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 shaft connecting block 42 and the first damper 41, and the first pressing block 43 is rotatably connected to the shaft connecting block 42 through the second rotating shaft 44. The second rotating shaft 44 is parallel to and spaced apart from the first rotating shaft 3. During the closing process, the cabinet door 2 can rotate forward with the shaft connecting block 42. The shaft connecting block 42 can move the first pressing block 43, so that the first pressing block 43 presses against the first damper 41. The first damper 41 can apply movement resistance to the first pressing block 43, thereby slowing down the rotation speed of the shaft connecting block 42 and the cabinet door 2.

[0029] In this embodiment, the first damper 41 is a component capable of contacting the first pressing block 43 and providing reverse resistance to the moving first pressing block 43, such as... Figure 3 As 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 impede the speed of the push rod moving back and forth.

[0030] like Figure 3 As shown, the shaft connecting 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 connecting block 42 also rotates synchronously with the first rotating shaft 3 and the cabinet door 2. A protruding connecting block is also provided on the shaft connecting block 42, and a shaft hole for installing the second rotating shaft 44 is provided on the connecting 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 connecting block 42 through the second rotating shaft 44, when the shaft connecting block 42 rotates, the first pressing block 43 is driven to move towards the first damper 41, and at the same time, the first pressing block 43 can also rotate around the axis of the second rotating shaft 44.

[0031] The first pressing block 43 is a component arranged between the shaft connecting block 42 and the first damper 41 for contacting the first damper 41. It has at least two connection relationships. First, it is rotatably connected to the shaft connecting block 42 via the second rotating shaft 44. Since the second rotating shaft 44 is biased to one side of the first rotating shaft 3, when the shaft connecting block 42 rotates, the shaft connecting block 42 can drive the first pressing block 43 to move closer to or away from the first damper 41. Second, the first pressing block 43 can contact the first damper 41. In particular, when the first pressing block 43 moves closer to and presses against the first damper 41, as the two get 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 combined action of the shaft connecting block 42 and the first damper 41, the first pressing block 43 will rotate around the axis of the second rotating shaft 44 during its movement. However, this does not affect the overall movement of the first pressing block 43 towards and against the first damper 41. On the contrary, it allows the first push rod 412 to slide smoothly along the inclined surface of the first pressing block 43. Of course, in a further technical solution, in order to limit the opening and closing angle of the first pressing block 43, a limiting block is also provided on the first pressing block 43 or the shaft connecting block 42. When the first pressing block 43 rotates to a predetermined angle, the first pressing block 43 and the shaft connecting block 42 are connected together through the limiting block and thus rotate synchronously together.

[0032] As can be seen from the above connection structure, by connecting the movable first pressing block 43 to the shaft connecting block 42 in an offset manner, the first pressing block 43 can both translate and rotate. The first pressing block 43 does not need to rotate with the shaft connecting block 42 by a large angle, but can achieve the pressure on the first damper 41 by swinging within a small range of its own rotation. This setting not only reduces the size and swing space of the shaft connecting block 42, but also makes the overall structure compact, occupies less space, and provides flexible transmission. Furthermore, by taking advantage of the fact that the rotation angle of the first pressing block 43 is smaller than that of the shaft connecting block 42, the first pressing block 43 only needs to be provided with a small contact surface to make contact with the first damper 41 and achieve a deceleration effect. This not only reduces the material usage 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.

[0033] Furthermore, the shaft connecting block 42 and the first damper 41 are respectively arranged on the cabinet door 2 and the cabinet body 1. The rotation of the shaft connecting block 42 is converted into a linear translational motion by the first top pressing block 43 as a connecting member. This is beneficial for coordinating 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 is the overall volume smaller, but it is also easy to control the first top pressing block 43 and the first damper 41 to maintain contact throughout or most of the stroke. This ensures that the cabinet door 2 can rotate slowly during most of the closing process. This not only provides a better user experience, but also greatly reduces the impact between the cabinet door 2 and the cabinet body 1, which is beneficial for improving the service life of the furniture.

[0034] A further technical solution may also include a cabinet partition 61, which is disposed on the upper side wall 11 of the cabinet body 1 and arranged in front of the first damper 41. The first pressing block 43 is arranged between the first damper 41 and the cabinet partition 61. When the cabinet door 2 is opened, it can rotate the shaft connecting block 42 in the opposite direction. Under the action of the shaft connecting block 42 and the first damper 41, the first pressing block 43 moves away from the first damper 41 and moves forward towards the cabinet partition 61. Viewed from front to back, the cabinet partition 61 at least covers the first damper 41 and at least part of the first pressing block 43, and can prevent the covered part of the first pressing block 43 from moving forward beyond the cabinet partition 61. The cabinet partition 61 serves two purposes: firstly, it can cover at least part of the first damper 41 and the first top pressure block 43 when the cabinet door 2 is opened, thus improving the overall aesthetics of the furniture; secondly, the cabinet partition 61 can also prevent the first top pressure block 43 from moving too far forward, which can reduce interference between components and provide support and positioning for the first top pressure block 43.

[0035] Since the cabinet partition 61 is located in front of the first damper 41, in one embodiment, the top of the cabinet partition 61 is also partially arranged between the first damper 41 and the shaft connecting block 42. In order to avoid the cabinet partition 61, the first pressing block 43 is L-shaped, including a horizontal arm 431 and a vertical arm 432. 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 61 and the first damper 41. The vertical arm 432 has an outwardly protruding arc-shaped first pressing surface 433 on the side facing the first damper 41. The first top pressure block 43 is configured in this way to form a bend, which effectively avoids the cabinet partition 61 while satisfying the transmission function; in addition, by setting the arc-shaped first abutment surface 433 on the vertical arm 432, the top rod of the first damper 41 can slide against the first abutment surface 433.

[0036] The first buffer device 4 is used to slow down the rotational speed of the cabinet door 2 when it closes. A further technical solution could include a second buffer device 5, which comprises a second damper 51 and a second pressing block 52. The second damper 51 is disposed on the upper side wall 11 of the cabinet body 1, and the second pressing block 52 is disposed on the cabinet door 2. During opening, the cabinet door 2 can rotate in the opposite direction along with the second pressing block 52. During rotation, the second pressing block 52 can contact the second damper 51, which applies rotational resistance to the second pressing block 52, thereby slowing down the reverse rotation speed of the second pressing block 52 and the cabinet door 2. By combining the first buffer device 4 and the second buffer device 5, the cabinet door 2 can be decelerated during both opening and closing, greatly improving the user experience. Furthermore, at least two of the first buffer devices 4 are 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 this arrangement is that when the cabinet door 2 is opened, a buffering force is provided to the cabinet door 2 near the middle of the cabinet door 2, reducing the deformation and shaking of the middle of the cabinet door 2.

[0037] A further technical solution is that the second pressing block 52, which is cam-shaped, has an arc-shaped second pressing surface 521 on the side facing the second damper 51. During the opening 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 outwardly protruding surface of the second pressing block 52, which is used to cooperate with the push rod of the second damper 51. Viewed in 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 purpose of this arrangement is to allow the second pressing block 52 to continuously press against the push rod of the second damper 51 when it rotates, so that the cabinet door 2 can be continuously buffered and resisted by the second damper 51 during the opening process.

[0038] A further technical solution could include a door partition 62 disposed on the cabinet door 2. The door partition 62 is arranged inside the second top pressing block 52 and extends towards the cabinet body 1. When the cabinet door 2 is closed, the free end of the door partition 62 and the free end of the cabinet partition 61 are close to each other. The advantage of this arrangement is that it forms a partition layer on the connection side between the cabinet door 2 and the cabinet body 1, effectively blocking external dust.

[0039] A further technical solution is 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 inclinedly arranged on the side wall of the cabinet body 1, with the angle between the first damper 41, the second damper 51 and the side wall of the cabinet body 1 being 15°~45°. The inclined arrangement of the first damper 41 and the second damper 51 allows the top rod to better meet the rotating first top pressure block 43 and the second top pressure block 52, allowing them to engage more quickly to buffer the cabinet door 2, thus improving the user experience when the cabinet door 2 is opened or closed.

[0040] To enable the cabinet door 2 to open and close automatically, a further technical solution may include a counterweight 7 connected to the upper end of the cabinet door 2, with the weight of the counterweight 7 not exceeding the weight of the cabinet door 2. When the cabinet door 2 is closed, its center of gravity is located in front of the axis of the first rotating shaft 3, and the center of gravity of the counterweight 7 does not extend beyond the axis of the first rotating shaft 3. When the cabinet door 2 rotates in the opposite direction under external force, the distance between the center of gravity of the counterweight 7 and the axis of the first rotating shaft 3 increases to a preset value, allowing the cabinet door 2 to automatically flip upward and open under the action of the counterweight 7. Conversely, when closing the cabinet door 2, when the cabinet door 2 rotates forward under external force, the distance between the center of gravity of the counterweight 7 and the axis of the first rotating shaft 3 decreases to a preset value, allowing the cabinet door 2 to automatically flip downward and close under the action of the counterweight 7. Furthermore, in order to reduce the collision between the counterweight 7 and the cabinet body 1, cushioning rubber is also provided on the side of the counterweight 7 or on the cabinet body 1.
