Description

Technical Field

[0001] This utility model relates to the field of sofa storage technology, specifically a telescopic storage and adjustment device for electric sofas. Background Technology

[0002] An electric sofa is a modern home furnishing product equipped with an electric device that allows for one-button adjustment of sitting and reclining positions via remote control or buttons, providing personalized and comfortable support. Its main features include enhanced comfort. To improve its storage performance, storage devices are usually installed inside the armrests on both sides of the sofa, thereby increasing the overall flexibility of the sofa's use.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN220494658U) discloses a telescopic storage and adjustment device for an electric sofa. The device includes two sets of side armrests, a seat cushion installed between the two sets of armrests, and the electric sofa body mounted on the top of the seat cushion. A storage box is installed inside the side armrests and seat cushion, with a slider on one side of the storage box and a groove on the outer side of the slider. An adjusting gear plate is installed on the other side of the storage box, and an adjusting gear meshes with one side of the adjusting gear plate. This utility model utilizes a rotating adjusting rod to drive the adjusting gear to rotate, which in turn drives the adjusting gear plate to move horizontally, thereby pushing the storage box out from inside the side armrests and seat cushion. The slider and groove work together to make the pushing process smoother, and the guide block and guide groove work together to ensure the storage box is pushed out along a predetermined path.

[0004] The aforementioned patent adjusts the position of the storage box using a gear and rack mechanism. Due to the limited size of the armrest area, the gear diameter is restricted. However, the displacement of the storage box is related to the size of the gear diameter. Because the gear diameter is small, the storage box usually needs to rotate the gear multiple times when it is extended or folded up. This reduces the flexibility of adjusting the position of the storage box, increases the intensity of operation, and reduces the comfort of use.

[0005] Therefore, this utility model provides a telescopic storage and adjustment device for electric sofas to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-9 As shown, this utility model provides a telescopic storage and adjustment device for an electric sofa, including a sofa body 1, with armrests 11 at both ends of the sofa body 1, and a storage cavity 12 inside the armrests 11; a storage box 2, which is inserted into the storage cavity 12, with an adjustment plate 21 fixedly connected to the inner wall of the storage box 2, and a partition 22 between the adjustment plates 21; a pull plate 3 and a positioning component 4, which are respectively located at the front and rear ends of the storage box 2, the pull plate 3 being used for pulling and adjusting the positioning component 4, and the positioning component 4 being used for abutting and positioning the storage box 2.

[0020] Furthermore, a support roller 13 is rotatably provided at the horizontal end of the storage cavity 12, and abutment grooves 14 are provided on both sides of the vertical end of the storage cavity 12. The upper half of the abutment groove 14 is inclined. A positioning cavity 15 is provided at the front end of the storage cavity 12, and the interior of the positioning cavity 15 is used for the hidden storage of the pull plate 3. The upper surface of the support roller 13 and the lower surface of the storage box 2 roll in contact with each other, further improving the flexibility of the storage box 2 to be pulled out and moved.

[0021] Furthermore, T-shaped grooves are formed on the sides of the adjusting plates 21 that are close to each other. A support shaft 23 is fixedly inserted through the interior of the partition plate 22, and arc-shaped locking blocks 24 are fixedly connected to both ends of the support shaft 23. The arc-shaped locking blocks 24 are set inside the T-shaped grooves and have an elliptical structure. A soft rubber pad 25 is fixedly connected to the bottom of the partition plate 22. Because the arc-shaped locking blocks 24 have an elliptical structure, their length and width are different, and their long side is aligned with the height direction of the partition plate 22, thus making the partition plate 22 vertical. The long side of the arc-shaped locking block 24 abuts against the inside of the T-shaped sliding groove of the adjusting plate 21, and the height of the T-shaped sliding groove is less than the height of the long side of the arc-shaped locking block 24. Thus, by pressing the arc-shaped locking block 24, the partition 22 is fixed against it. Conversely, when the partition 22 is rotated to a horizontal state, the short side of the arc-shaped locking block 24 does not contact the inner wall of the T-shaped sliding groove, so the horizontal sliding adjustment of the partition 22 can be realized. The support shaft 23 is consistent with the width of the opening of the narrow side of the center of the T-shaped sliding groove, which plays a good guiding and limiting role.

[0022] Furthermore, a guide groove 31 is provided on the side of the pull plate 3 away from the storage box 2, and a guide shaft 32 is fixedly connected to the inner wall of the guide groove 31. A first spring 33 is sleeved on the outside of the guide shaft 32, and a pull rod 34 is sleeved on the outside of the guide shaft 32. A traction rope 35 is fixedly connected to the bottom of the pull rod 34. The positioning component 4 includes a positioning seat 41, a guide plate 43 is fixedly connected to the inner wall of the positioning seat 41, and an abutment block 42 is slidably connected between the guide plates 43. The bottom of the abutment block 42 is fixedly connected to the end of the traction rope 35 away from the pull rod 34. When the pull rod 34 is pulled upward by holding the pull plate 3, the pull rod 34 moves upward and drives the abutment block 42 downward through the traction rope 35, thereby releasing the abutment block 42 from the abutment groove 14. Guide holes are provided on the positioning seat 41, the storage box 2, and the pull plate 3 at the corresponding positions of the traction rope 35 for auxiliary limiting of the pulling path of the traction rope 35.

[0023] Furthermore, a telescopic shaft 44 is fixedly connected to the lower surface of the abutment block 42, and the other end of the telescopic shaft 44 is fixedly connected to the inner wall of the positioning seat 41. A second spring 45 is sleeved on the outside of the telescopic shaft 44. With the support and cooperation of the telescopic shaft 44 and the second spring 45, the abutment block 42 abuts upward under the elastic support of the second spring 45, thereby ensuring that the abutment block 42 abuts against the abutment groove 14. Two sets of abutment blocks 42 are symmetrically arranged, and the ends of the two sets of abutment blocks 42 that are far apart from each other are inclined. The inclined abutment blocks 42 and the inclined abutment groove 14 abut against each other and are fixed. The surfaces of the inclined abutment blocks 42 and the inclined abutment groove 14 are provided with anti-slip textures. Through the mutual abutment contact between the inclined surfaces of the abutment blocks 42 and the abutment groove 14, the auxiliary positioning of the storage box 2 is achieved, which ensures the stability of the storage box 2 in the closed and unfolded state and prevents the storage box 2 from sliding at will.

[0024] Working principle: When retrieving items from the storage box 2, by holding the pull plate 3 and the pull rod 34 and pulling the pull rod 34 upward, the traction rope 35 will drive the abutment block 42 downward, releasing the abutment block 42 from the abutment groove 14. At the same time, the pull plate 3 can be pulled back and forth to pull out the storage box 2. When the pull rod 34 is released, the pull rod 34 moves downward under the abutment of the first spring 33, while the abutment block 42 moves upward under the abutment of the second spring 45, ensuring the tension effect of the traction rope 35 and making the abutment block 42 abut against the abutment groove 14, thus completing the auxiliary positioning of the storage box 2.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
