Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing, and in particular to a silent buffer door assembly and its application in wardrobes. Background Technology

[0002] A wardrobe is a piece of furniture used to store clothes, bedding, and other daily necessities. It typically consists of a cabinet and doors and is widely used in bedrooms, walk-in closets, and other spaces, serving functions such as storage, dust protection, and aesthetics. As people's living standards improve, they also have higher requirements for the user experience of wardrobes, especially the quietness and smoothness of the doors opening and closing.

[0003] Existing wardrobe sliding doors tend to generate significant impact during closing, leading to noise and structural damage. Some products lack effective cushioning devices and operate unevenly, affecting user comfort and product lifespan. Utility Model Content

[0004] In order to overcome the shortcomings of existing wardrobe sliding doors, which are prone to generating large impact forces during closing, resulting in loud noise and easy structural damage, the purpose of this utility model is to provide a silent buffer door assembly and its application in wardrobes.

[0005] The technical solution of this utility model is: a wardrobe with a silent buffer door assembly and its application, including a cabinet, a sliding door, a connecting frame, a first elastic element, a buffer plate, a guide rail, a buffer block, and a second elastic element. Sliding doors are slidably connected to the left and right sides of the front end of the cabinet. A guide rail is provided on the front side of the inner bottom end of the cabinet. The top of the guide rail has symmetrically opened mounting grooves. The bottom end of the left sliding door is slidably connected to the front mounting groove, and the bottom end of the right sliding door is slidably connected to the rear mounting groove. A second elastic element is connected to the left end of the front mounting groove and the right end of the rear mounting groove. A buffer block is connected to the other end of each second elastic element. The buffer block slides within the mounting groove. At the point where the buffer block contacts the sliding door, a connecting frame is installed on the inner left and right walls of the cabinet. A buffer plate is slidably connected within each connecting frame. The buffer plate in the left connecting frame abuts against the left sliding door, and the buffer plate in the right connecting frame abuts against the right sliding door. First elastic elements are sequentially spaced from top to bottom at the end of the buffer plate away from the sliding door. The other end of each first elastic element is connected to the connecting frame.

[0006] Furthermore, it also includes fixed plates, sliding rods, and pulley sets. Fixed plates are symmetrically arranged at the top front and back of the inner top of the box, forming a cavity between the two fixed plates. Sliding rods are symmetrically arranged in the cavity. Pulley sets are symmetrically connected to both sliding rods. The two pulley sets on the front sliding rod are connected to the sliding door on the left, and the two pulley sets on the rear sliding rod are connected to the sliding door on the right.

[0007] Furthermore, it also includes iron sheets and magnetic blocks. Iron sheets are embedded in the end of each sliding door near the buffer plate, and magnetic blocks are arranged at intervals from top to bottom on the end of the buffer plate near the sliding door. The magnetic blocks attract the iron sheets.

[0008] Furthermore, it also includes wheels, with wheels symmetrically arranged on the left and right sides of the bottom of the box.

[0009] Furthermore, it also includes sponge blocks, which are symmetrically arranged between the two fixing plates.

[0010] Furthermore, it also includes sound-absorbing foam. Sound-absorbing foam is provided on the front and rear inner walls of both mounting slots, and at the junction of the sound-absorbing foam and the sliding door.

[0011] Furthermore, both sliding doors have push-pull grooves at their front ends.

[0012] The beneficial effects are: 1. By setting up a first elastic element, a second elastic element, a buffer plate and a buffer block, this utility model realizes multi-level buffering and shock absorption during the closing process of the sliding door, effectively reducing the impact force and noise when the sliding door closes.

[0013] 2. The combination of the magnet block and the iron sheet further enhances the stability and smoothness when closing the door; the design of the pulley group and sliding rod improves the smoothness of the sliding door's operation and reduces frictional resistance; the sponge block and sound-absorbing sponge further absorb vibration and impact noise, and the overall structure significantly improves the user experience and the product's durability.

Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] A silent buffer door assembly and its application in wardrobes, such as Figures 1-5 As shown, the device includes a housing 1, sliding doors 2, a connecting frame 3, a first elastic element 301, a buffer plate 302, a guide rail 4, a buffer block 401, and a second elastic element 402. Sliding doors 2 are slidably connected to the left and right sides of the front end of the housing 1. Each sliding door 2 has a push-pull groove 201 at its front end, facilitating opening and closing. A guide rail 4 is located on the front side of the inner bottom of the housing 1. The top of the guide rail 4 has symmetrical mounting grooves 404. The bottom end of the left sliding door 2 is slidably connected to the front mounting groove 404, and the bottom end of the right sliding door 2 is slidably connected to the rear mounting groove 404. The left end of the front mounting groove 404 and the right end of the rear mounting groove 404 are both connected... There is a second elastic element 402, and the other end of the second elastic element 402 is connected to a buffer block 401. The buffer block 401 slides in the mounting groove 404. At the junction of the buffer block 401 and the sliding door 2, the inner left and right walls of the box body 1 are equipped with connecting frames 3. The buffer plates 302 are slidably connected in the connecting frames 3. The buffer plate 302 in the left connecting frame 3 abuts against the left sliding door 2, and the buffer plate 302 in the right connecting frame 3 abuts against the right sliding door 2. The end of the buffer plate 302 away from the sliding door 2 is provided with first elastic elements 301 at intervals from top to bottom. The other end of the first elastic element 301 is connected to the connecting frame 3. Both the first elastic element 301 and the second elastic element 402 are springs.

[0022] like Figure 2 and Figure 5As shown, it also includes a fixed plate 102, a sliding rod 202, and a pulley assembly 203. The fixed plates 102 are symmetrically arranged at the top of the inner end of the housing 1, forming a cavity between the two fixed plates 102. The sliding rods 202 are symmetrically arranged in the cavity. The pulley assemblies 203 are symmetrically connected to the two sliding rods 202. The two pulley assemblies 203 on the front sliding rod 202 are connected to the left sliding door 2, and the two pulley assemblies 203 on the rear sliding rod 202 are connected to the right sliding door 2. The pulley assemblies 203 roll on the sliding rods 202 to guide the opening and closing of the sliding door 2. Compared with the direct sliding contact between the sliding door 2 and the housing 1 (rolling friction is much less than sliding friction), this can significantly reduce the resistance when opening and closing the door, making the user operation easier and less strenuous. Moreover, the noise generated by rolling friction is much less than that of sliding friction. With appropriate lubrication, the sliding door can be opened and closed almost silently, providing a quieter operating environment.

[0023] like Figure 5 As shown, it also includes iron sheets 205 and magnet blocks 303. Iron sheets 205 are embedded in one end of each sliding door 2 near the buffer plate 302. Magnet blocks 303 are arranged at intervals from top to bottom on one end of the buffer plate 302 near the sliding door 2. The magnet blocks 303 attract the iron sheets 205. When the sliding door 2 is close to the fully closed position, the attraction between the magnet blocks 303 and the iron sheets 205 can help ensure that the sliding door 2 can be closed accurately and stably to the predetermined position.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes wheels 101, sponge blocks 204, and sound-absorbing sponges 403. Wheels 101 are symmetrically arranged on the left and right sides of the bottom of the cabinet 1. The wheels 101 facilitate the user to move this wardrobe. Sponge blocks 204 are symmetrically arranged between the two fixed plates 102. When the pulley group 203 hits the sponge block 204, the sponge block 204 will absorb the impact force from the pulley group 203. The sponge block 204 can also reduce the noise generated when the pulley group 203 hits. Sound-absorbing sponges 403 are provided on the front and rear inner walls of the two mounting grooves 404. At the junction of the sound-absorbing sponge 403 and the sliding door 2, when the sliding door 2 slides in the mounting groove 404, the sound-absorbing sponge 403 can absorb the noise generated when the sliding door 2 slides, further reducing the noise when the sliding door 2 opens and closes.

[0025] The initial state of this wardrobe can be referenced. Figure 1When a user needs to open the wardrobe, they can push the right sliding door 2 to the left via the push-pull groove 201, thus opening the right sliding door 2. During this process, the magnet 303 separates from the iron plate 205, and the bottom end of the right sliding door 2 slides to the left along the rear mounting groove 404. Simultaneously, the right sliding door 2 drives the pulley group 203 on it to move synchronously along the rear sliding rod 202. When the user closes the right sliding door 2, they pull the right sliding door 2 to the right. Initially, the right sliding door 2 first contacts the right buffer block 401. The buffer block 401 moves to the left under the action of the sliding door 2, providing a buffering effect. During this process, the second elastic element 402 gradually changes from its initial state to a compressed state, providing buffering resistance and reducing... The impact force generated by the movement of the sliding door 2 causes the pulley group 203 on the sliding door 2 to move synchronously on the sliding rod 202. When the right sliding door 2 is close to the closed position, the user stops pushing the sliding door 2. Under the action of inertia, the sliding door 2 will abut against the buffer plate 302 on the right. The iron plate 205 on the sliding door 2 attracts the magnet block 303 on the buffer plate 302. The buffer plate 302 is squeezed by the sliding door 2 in the connecting frame 3 and slides to the right. The first elastic element 301 gradually changes from the initial state to the compressed state. The first elastic element 301 absorbs the remaining kinetic energy of the sliding door 2 through elastic deformation. After that, the first elastic element 301 gradually returns to its original state and pushes the sliding door 2 to the right side of the front end covering the box body 1. This achieves the flexible stop of the sliding door 2. The left sliding door 2 can also be opened and closed in the same way.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
