Description

Technical Field

[0001] This utility model relates to the field of sofas, specifically a sofa with lighting function. Background Technology

[0002] As an indispensable piece of furniture for sitting and lying down in modern home life, the core function of the sofa has always revolved around providing a comfortable resting space. Since the birth of the prototype of the modern sofa design, its structure has undergone iterations from hard wooden frames filled with straw to spring support and high-density foam, and the materials have also expanded from a single fabric to a variety of choices such as leather and composite materials. With the improvement of living standards, consumers' needs for sofas have gradually extended from basic sitting and lying functions to multifunctional and scenario-based features.

[0003] Traditional home lighting primarily uses ceiling lights or floor lamps to provide overall ambient lighting. However, with increasing attention to space utilization efficiency and user experience, the importance of localized lighting is becoming increasingly apparent. For example, scenarios such as reading, crafting, and nighttime living require focused light sources to reduce eye strain. To optimize space utilization and enhance user experience, the integrated design of furniture and lighting equipment is gradually becoming an innovative direction in the industry. For instance, the Chinese authorized patent CN216256320U (a leisure sofa with lighting function) includes a sofa body with a right support box fixedly connected to its right side; a left support box with a connecting column fixedly connected to its top, and a support platform movably inserted into the outer wall of the connecting column; and a telescopic mechanism including a fixed column, a rotating handle, and a lifting cylinder. This leisure sofa with lighting function, through the positional connection relationship between the rotating handle, rotating gear, transmission gear, rotating column, lifting column, curved plate, connecting cylinder, sliding groove, lifting cylinder, and the lamp body, allows the lifting cylinder to move downwards by rotating the rotating handle, facilitating the lamp body to be stored inside the left support box, making it easy to store the lamp body and preventing people from bumping into it.

[0004] While the aforementioned existing technology can save space by combining sofa and lighting, the side storage of the lamps requires a large support box for even smaller lamps. The support box has a large floor area, and since the lamps are located on the side and the light is directed downwards, people need to lean to one side on the sofa to get a good lighting effect when reading or for other lighting needs. Utility Model Content

[0005] The purpose of this utility model is to provide a sofa with lighting function, so as to solve the problems mentioned in the background art, which are that side storage of lamps makes the overall sofa occupy a larger area, and the lamps are located on the side, requiring the body to be turned to one side on the sofa to obtain a better lighting effect when reading or other lighting needs are required.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sofa with lighting function, including a sofa frame, the sofa frame including a sitting / reclining part, a backrest integrally connected to the rear end of the upper end of the sitting / reclining part, an upper arc-shaped extension fixed to the upper end of the backrest, the upper arc-shaped extension being arc-shaped, an arc-shaped storage groove provided in the upper arc-shaped extension, the front end of the arc-shaped storage groove extending to the front end face of the upper arc-shaped extension, a lamp unit connected in cooperation within the upper arc-shaped extension, the lamp unit including an arc-shaped rotating plate, the arc-shaped rotating plate sliding along the upper end of the arc-shaped storage groove, and multiple lamp bodies arrayed at the front end of the lower end of the arc-shaped rotating plate, the lamp bodies illuminating light in the rear-lower direction.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-6 This utility model provides an embodiment of a sofa with lighting function, including a sofa frame 1. The sofa frame 1 provides basic support for the entire sofa, ensuring the stability of the sofa structure. A seating / reclining section 2 is mounted on the sofa frame 1, allowing the user to comfortably sit or lie on it. A backrest 5 is integrally connected to the upper rear end of the seating / reclining section 2. This integral connection ensures a tight connection between the backrest 5 and the seating / reclining section 2, providing stable support for the user's back and improving seating / reclining comfort. Support legs 3 are fixed at the four corners of the lower end of the seating / reclining section 2, providing stable support for the sofa and ensuring it does not wobble during use. Armrest seats 4 are integrally connected to both sides of the upper end of the seating / reclining section 2 along both sides of the backrest 5. The connection between the armrest seats 4 and the backrest 5 and the seating / reclining section 2 is smooth, resulting in a smooth and aesthetically pleasing appearance for the sofa, avoiding sharp edges at the joints, and improving the sofa's safety and comfort.

[0026] An upper arc-shaped extension 6 is fixed to the upper end of the backrest 5. The arc shape of the upper arc-shaped extension 6 adds to the sofa's stylishness and provides suitable space for the installation of subsequent components. An arc-shaped storage groove 7 is opened inside the upper arc-shaped extension 6. The front end of the arc-shaped storage groove 7 extends to the front end face of the upper arc-shaped extension 6, providing space for the storage and rotation of the lighting unit 11, so that the lighting fixture can be hidden inside when not in use, keeping the sofa's appearance neat.

[0027] The upper arc-shaped extension 6 is fitted with a lamp unit 11. The arc-shaped rotating plate 12 of the lamp unit 11 can slide along the upper end of the arc-shaped storage groove 7, allowing for flexible adjustment of the lamp. Multiple lamp bodies 16 are arrayed at the lower front end of the arc-shaped rotating plate 12. The light irradiation direction of the lamp bodies 16 is downward and rearward. Due to the arc shape of the arc-shaped rotating plate 12, the lamp bodies 16 are embedded in the arc-shaped rotating plate 12. Due to the presence of the chamfer, the angle of the irradiation line is slightly biased to the rear. Multiple lamp bodies 16 work together to provide uniform and sufficient lighting, fully covering the area around the sofa.

[0028] The curved rotating plate 12 is integrally connected to the side curved limiting plates 13 on both sides. The longitudinal plane dimension of the side curved limiting plates 13 matches the longitudinal plane dimension of the curved storage groove 7. This matching design allows the curved rotating plate 12 and the side curved limiting plates 13 to slide along the curved storage groove 7, ensuring stable and precise rotation of the lighting unit 11, avoiding deviation or shaking, and improving the lighting effect. The front end of the curved rotating plate 12 is fixed to the front end of the upper curved extension 6. The vertical plane dimension of the front fixing plate 14 is larger than the vertical plane dimension of the curved storage groove 7. The front fixing plate 14 serves as a limiting and decorative element, preventing the lighting unit 11 from being over-retracted when stored, while also making the sofa look more beautiful and elegant.

[0029] The upper arc-shaped extension 6 has a fixed equipment housing 9 at the middle of its upper end. The equipment housing 9 provides installation and protection space for the internal equipment. A drive motor 17 is installed on one side inside the equipment housing 9. The drive motor 17 provides power support for the rotation of the lighting unit 11, ensuring stable and reliable power.

[0030] Inside the equipment housing 9, a drive gear 18 is installed along the output shaft of the drive motor 17. An arc-shaped rack 15 is fixed to the lower center of the rear end of the arc-shaped rotating plate 12. An arc-shaped slot 8 is formed in the middle of the rear end face of the upper arc-shaped extension 6. The arc length of the slot 8 is greater than the arc length of the rack 15, and the rack 15 passes through the slot 8 to mesh with the drive gear 18. Rectangular clearance slots 10 are formed at the connection points between the equipment housing 9 and the rack 15. Note that the actual dimensions of the drive structure, including the drive motor 17, rack 15, and drive gear 18, are smaller than those shown in the diagram. The proportions in the diagram have been slightly adjusted to clearly illustrate the connections.

[0031] When there is a lighting requirement, the control drive motor 17 is activated, and the drive motor 17 drives the drive gear 18 to rotate. Since the drive gear 18 is meshed with the arc-shaped rack 15, and the upper arc-shaped extension 6 has an arc-shaped storage groove 7 and an arc-shaped slot 8, the lamp unit 11 will rotate forward along the arc-shaped storage groove 7, exposing the area where the lamp body 16 is located.

[0032] When the main body 16 of the lamp is turned on, the lighting fully covers the area where the sofa frame 1 is located. When the user sits or lies on the upper part of the sitting or lying section 2, the main body 16 of the lamp provides lighting from top to bottom, meeting the lighting needs of the user for various activities on the sofa.

[0033] The drive motor 17 and the lamp body 16 are connected to the controller and power supply via wiring. The controller and power supply are also connected via wiring. The controller can control the drive motor 17 and the lamp body 16 to turn on separately, and the power supply will provide power. The controller is installed in a suitable position on the sofa frame 1, such as the side of the armrest seat 4 or the back of the backrest 5. This control method is simple and can be achieved by using a ready-made controller connected to the power supply.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
