Description

Technical Field

[0001] This utility model relates to the field of door panel structure technology, and more specifically, to a door panel structure with a concealed handle. Background Technology

[0002] In the field of furniture design and manufacturing, door panels, as an important component, are significantly affected by the design of their handles. This not only impacts the overall aesthetics of the furniture but also the user's convenience and safety. Traditional door handles are mostly external, directly mounted on the door panel surface. While convenient to operate, these handles have several drawbacks.

[0003] First, the protruding handles disrupt the overall smoothness and simplicity of the door panel, making the furniture appear less refined and failing to meet modern consumers' pursuit of a minimalist style in home furnishings. For example, in some modern home decorations that pursue an extremely minimalist style, the abruptness of the protruding handles clashes with the overall decoration style.

[0004] Secondly, external handles pose certain safety hazards during daily use. Because they protrude from the door panel, people are prone to accidentally bumping into them in high-traffic areas, especially in environments where children play, leading to injuries. In particular, the sharp edges of the handles can cause more serious scratches. Utility Model Content

[0005] Based on the above-mentioned technical problems, this utility model proposes a door panel structure with a concealed handle.

[0006] A door panel structure with a concealed handle includes a door panel body, one side of which is rotatably mounted to a cabinet, and the other side is provided with a concealed handle structure.

[0007] Concealed handle structure:

[0008] Snap-on plate and slot design: The concealed handle structure includes a snap-on plate and a latch assembly. A recessed slot is provided in the middle of the side of the main body of the door panel. A notch is provided on the outer side of the slot. The snap-on plate is installed at the notch through a hinge shaft. When the snap-on plate is in the closed state, its outer side is flush with the surface of the main body of the door panel, and the gap between the snap-on plate and the edge of the notch is ≤0.5mm. This tight fit design ensures the flatness and aesthetics of the door panel surface, making the handle almost invisible when not in use, without damaging the overall appearance of the door panel.

[0009] The latch assembly is linked to the sliding plate: At least one pin groove is provided on the side of the opening slot, and a slidable and extendable latch is provided in the pin groove. The rear side of the latch is connected to a sliding reset assembly. A sliding plate is provided in the opening slot, and the lower end of the sliding plate is fixedly connected to the sliding reset assembly. The upper part of the sliding plate passes through a slide groove on one side of the opening slot. When the buckle is rotated, it can push the sliding plate to move backward along the slide groove, thereby driving the latch to retract. Through this linkage structure, the hidden operation of the handle is realized. When it is necessary to open the door panel, the finger presses the movable end of the buckle, rotates the buckle, and drives the latch to retract, making it easy to pull the door panel. After the door panel is closed, the latch extends outward under the action of the sliding reset assembly, which plays a certain positioning and fixing role.

[0010] Details of the sliding reset assembly: The sliding reset assembly includes a slide rod and a reset elastic element. The slide rod slides in conjunction with a base rod fixed to the bottom of the pin groove. Guide pins are symmetrically arranged on both sides of the slide rod. The guide pins slide in conjunction with the guide groove of the door panel body. The reset elastic element is sleeved on the guide pins or the base rod and is used to drive the slide rod to reset. This design ensures that the pin can be stably reset after retraction, ensuring the reliability and stability of the handle structure.

[0011] Other optimized designs: The extension length of the pin is less than the rearward movement length of the slide plate, ensuring that the pin can fully retract without obstructing door panel operation. Multiple pin slots are provided on the side of the opening groove, and the slide plates are fixedly connected within the opening groove by a straight plate. An arc-shaped transition surface is provided on the outer side of the straight plate to facilitate manual operation of the latch plate and improve user comfort. The hinge shaft is a damping pivot, and after the latch plate is reset, it forms a sealed fit with the notch, making the latch plate rotation smoother and enhancing the door panel's sealing performance, reducing dust and other contaminants entering the cabinet. The reset elastic element is a compression spring or an elastic rubber component. One end of the compression spring abuts against the slide rod, and the other end abuts against the bottom of the pin slot, providing reliable elastic force for the reset of the slide rod and the pin.

[0012] Beneficial effects:

[0013] 1. Enhanced Aesthetics: The concealed handle design makes the door panel surface smooth and simple, perfectly matching the minimalist style of modern homes, greatly enhancing the overall aesthetics of the furniture and satisfying consumers' pursuit of a high-quality home appearance.

[0014] 2. Enhanced safety: Eliminates the collision hazards caused by protruding external handles, especially in home environments where children are active, effectively reducing the risk of accidental injury and ensuring the safety of users.

[0015] 3. Improved structural stability and durability: The linkage structure between the latch and the sliding plate, as well as the rational design of the sliding reset component, ensure the stability of the handle during frequent use, reduce the possibility of component loosening and damage, and extend the service life of the door handle structure. At the same time, the sealing fit between the buckle and the notch, as well as the application of the damping pivot, further improve the stability and durability of the entire structure.

[0016] 4. Optimized operating experience: The damping pivot ensures smooth rotation of the buckle, and the rounded transition surface on the outer side of the straight plate provides users with a comfortable operating feel, improving the convenience and enjoyment of daily use.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] like Figures 1-5 The door panel structure shown includes a door panel body 1, one side of which is rotatably mounted to the cabinet, and the other side is provided with a hidden handle structure.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Overall layout of door panel body 1 and concealed handle structure: One side of door panel body 1 is installed in the cabinet by conventional rotating connection methods such as hinges, and the other side is equipped with a concealed handle structure.

[0027] The recessed groove 2 in the concealed handle structure is recessed in the middle of the side of the door panel body 1. The notch 3 on the outer side of the recessed groove 2 is used to install the snap plate 4. The snap plate 4 is installed at the notch 3 through the hinge shaft (damping shaft). When the snap plate 4 is closed, its outer side is flush with the surface of the door panel body 1 with a very small gap (≤0.5mm). The handle trace is almost invisible from the appearance, ensuring the overall aesthetics of the door panel.

[0028] When in use, fingers can be pressed from the outside of the buckle plate 4 and inserted into the notch 3. In addition, in order to ensure that the fingers can be stuck in the opening groove 2, the height of the opening groove 2 must be such that the fingers can be inserted into the opening groove 2 after the buckle plate 4 is rotated inward by more than 90°.

[0029] Working principle of the pin 6 assembly and the sliding plate 8: The side of the opening slot 2 is provided with a pin groove 5. Taking two pin grooves 5 as an example (the principle is the same for multiple pin grooves 5), each pin groove 5 has a slidable and outwardly extending pin 6. The rear side of the pin 6 is connected to the sliding reset assembly. The slide rod 10 in this assembly forms a sliding engagement relationship with the bottom rod 11 fixed at the bottom of the pin groove 5. Guide pins 12 are symmetrically arranged on both sides of the slide rod 10. The guide pins 12 slide with the corresponding guide grooves on the door panel body 1 to ensure the stability of the slide rod 10 during the sliding process. For example, the reset elastic element is a compression spring 13. The compression spring 13 is sleeved on the guide pin 12, with one end abutting the bottom of the pin groove 5 and the other end connected and fixed to the front of the guide pin 12; or the compression spring 13 is set on the slide rod 10, with one end abutting the bottom of the pin groove 5 and the other end connected and fixed to the slide rod 10. In this case, the guide pin 12 only has a guiding function.

[0030] Selection and function of the reset elastic element: The reset elastic element can be a compression spring 13 or an elastic rubber part. Taking the compression spring 13 as an example, its good elastic performance can provide a stable and reliable reset force for the slide bar 10 and the pin 6. During long-term use, the compression spring 13 can withstand multiple expansion and contraction deformations, ensuring the normal operation of the pin 6 assembly. It is not easy for the pin 6 to fail to reset due to insufficient elasticity, thereby extending the service life of the handle structure.

[0031] The lower end of the slide plate 8 in the opening slot 2 is fixedly connected to the slide rod 10. The upper part of the slide plate 8 passes through the slide groove 7 on one side of the opening slot 2. When the user needs to open the door panel, he rotates the buckle plate 4. The buckle plate 4 pushes the slide plate 8 to move backward along the slide groove 7. The slide plate 8 drives the slide rod 10 to move backward, so that the latch 6 retracts into the pin groove 5. At this time, the door panel can be easily pulled. When the door panel is closed, under the elastic force of the compression spring 13, the slide rod 10 drives the slide plate 8 and the latch 6 to reset. The latch 6 extends outward, which plays a certain role in positioning and fixing the door panel.

[0032] It should be noted that the width of the buckle plate 4 should be sufficient to push the skateboard 8 to move when the buckle plate 4 rotates, and the buckle plate 4 should still be in contact with the skateboard 8 when the finger can be hooked into the opening slot 2.

[0033] The cooperation of multiple pin slots 5 and straight plate 9: When multiple pin slots 5 are set on the side of the opening slot 2, the slide plates 8 are fixedly connected to each other as a whole by the straight plate 9. This design allows each pin 6 to move synchronously, enhancing the integrity and stability of the structure. The outer side of the straight plate 9 is provided with an arc-shaped transition surface. When the user rotates the buckle plate 4, the hand contacts the arc-shaped transition surface, making the operation more comfortable and easier to apply force. For example, in daily use, both adults and children can easily operate the handle structure through the buckle plate 4.

[0034] Advantages of the damping pivot and sealing fit: The hinge shaft adopts a damping pivot, which makes the buckle plate 4 have a smooth feel during rotation, meeting the needs of normal use. When the buckle plate 4 is reset, it forms a sealing fit with the notch 3. This design not only enhances the sealing of the door panel, preventing dust, moisture and other substances from entering the cabinet and protecting the items inside the cabinet, but also further enhances the overall aesthetics of the door panel, making the handle structure more naturally integrated with the main body of the door panel 1.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
