[0002] A sofa is a piece of home furniture typically used for sitting, lying down, and resting, and is widely used in living rooms, offices, and other spaces. Sofa designs typically combine comfort and aesthetics, utilizing a variety of materials (such as fabric, leather, and wood) and styles to provide a relaxing, social, and functional space. A sofa controller is a device used to adjust the functions of a sofa, typically found on electric or smart sofas. It controls various functions of the sofa, such as adjusting the backrest angle to ensure a comfortable sitting or reclining position.

[0003] However, conventional sofa controllers generally only control the sofa and lack the ability to charge a phone, which limits the practicality of the sofa, especially when the sofa is used for extended periods of time. Furthermore, the lack of a charging function in sofa controllers requires users to use an additional charger or socket to charge their phone, increasing cable clutter and the number of devices in the home.

[0004] Therefore, those skilled in the art provide an electric sofa extension cord controller to solve the problems raised in the above background technology. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1-Figure 7 , an embodiment provided by the utility model:

[0028] The electric sofa telescopic cord controller includes a shell 1, a No. 1 mounting plate 4, a No. 2 mounting plate 6 and a limiting mechanism 13. The No. 1 mounting plate 4 and the No. 2 mounting plate 6 are fixedly provided with a No. 1 fixing plate 5 and a No. 2 fixing plate 7 at opposite ends respectively. The No. 2 mounting plate 6 and the No. 1 mounting plate 4 are fixedly provided with a motor 9 at opposite ends. A rotating column 8 is rotatably provided at the output end of the motor 9. A wire binding roller 10 is rotatably provided at the middle position of the rotating column 8. A charging wire 12 is wrapped around the outer end of the wire binding roller 10. A gear 11 is fixedly provided at the other end of the rotating column 8. The wire binding roller 10 is rotatably provided between the No. 1 fixing plate 5 and the No. 2 fixing plate 7. The gear 11 is rotatably provided between the No. 1 fixing plate 5 and the No. 1 mounting plate 4. A top plate 2 is fixedly provided at the upper end of the shell 1. Two buttons 3 are provided on one side of the top plate 2. A mounting groove 14 is provided on the other side of the top plate 2. The charging wire 12 passes through the mounting groove 14 and reaches the upper end of the top plate 2.

[0029] Specifically, button 3 can control the extension and retraction of the sofa, and a charging cable 12 is provided at the outer end of the wire binding roller 10 of the present invention. After the charging cable 12 is pulled outward, the mobile phone can be charged, so that the user can charge conveniently while using the sofa, thereby improving the practicality of the sofa. When the charging cable 12 is extended or retracted, the limiting mechanism 13 can limit the extended length of the charging cable 12, preventing the charging cable 12 from being overstretched or entangled, protecting the integrity of the charging cable 12 and extending its service life.

[0030] Reference Figure 8 The limiting mechanism 13 includes a movable column 1301 and a No. 1 spring 1303. The front end of the movable column 1301 is provided with a pawl 1302, and the rear end of the pawl 1302 is provided with a No. 2 spring 1304.

[0031] The movable column 1301 passes through the housing 1 and the first mounting plate 4, and extends between the first mounting plate 4 and the first fixed plate 5. The pawl 1302 is engaged with the gear 11.

[0032] One end of the No. 1 spring 1303 is fixedly arranged at the front end of the No. 1 mounting plate 4 , and the other end of the No. 1 spring 1303 is fixedly arranged at the upper end of the pawl 1302 .

[0033] Specifically, when the charging cable 12 is pulled out, the pawl 1302 is engaged with the gear 11, and the pulling out of the charging cable 12 will drive the wire binding roller 10 to rotate, thereby driving the gear 11 to rotate. The pawl 1302 can prevent the gear 11 from reversing. Since there is a longer wire in the housing 1, the charging cable 12 will not be torn when it is pulled out. Limiting the gear 11 by the pawl 1302 can effectively prevent the charging cable 12 from being torn during the pulling out process, thereby extending the service life of the charging cable 12. When the charging cable 12 needs to be retracted, first pull the movable column 1301 backward, the No. 2 spring 1304 will be compressed, and then turn on the motor 9. The rotating column 8 drives the wire binding roller 10 to retract the charging cable 12, and the charging cable 12 can be quickly retracted, saving time and energy.

[0034] Working principle: Button 3 can control the extension and retraction of the sofa, and a charging cable 12 is provided at the outer end of the wire-binding roller 10. After the charging cable 12 is pulled outward, the mobile phone can be charged. When the charging cable 12 is extended or retracted, the limit mechanism 13 can limit the length of the extension of the charging cable 12.

[0035] Secondly, when the charging cable 12 is pulled out, the pawl 1302 is engaged with the gear 11, and the pulling out of the charging cable 12 will drive the cable binding roller 10 to rotate, thereby driving the gear 11 to rotate. The pawl 1302 can prevent the gear 11 from reversing. Since there is a longer wire in the housing 1, the charging cable 12 will not be torn when it is pulled out. When the charging cable 12 needs to be retracted, first pull the movable column 1301 backward, the No. 2 spring 1304 will be compressed, and then turn on the motor 9, and the rotating column 8 drives the cable binding roller 10 to retract the charging cable 12.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
