[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a multifunctional folding sofa bed, including a sofa bed body 1. A mounting groove 3 is provided on one side of the sofa bed body 1, and a lifting mechanism 4 is fixedly installed inside the mounting groove 3. A support mechanism 2 is fixedly installed on one side of the lifting mechanism 4. The support mechanism 2 includes a mounting plate 201, and a damping adjustment mechanism 202 is fixedly installed on the top of the mounting plate 201. A first adjusting arm 203 is rotatably mounted on the top of the mounting plate 201 via the damping adjustment mechanism 202. A second adjusting arm 204 is rotatably mounted on one side of the first adjusting arm 203 via the damping adjustment mechanism 202. A third adjusting arm 205 is rotatably mounted on one end of the second adjusting arm 204 via the damping adjustment mechanism 202. One end of the third adjusting arm 205 is rotatably mounted with a fourth adjusting arm 206 via a damping adjusting mechanism 202. One end of the fourth adjusting arm 206 is rotatably mounted with a fifth adjusting arm 207 via the damping adjusting mechanism 202. A damping ball joint 208 is fixedly mounted on one end of the fifth adjusting arm 207, and a magnetic chuck 209 is fixedly mounted on one end of the damping ball joint 208. The damping adjusting mechanism 202 includes a mounting rod 2021, a fixing plate 2022 fixedly mounted on one side of the mounting rod 2021, a friction plate 2023 slidably mounted on the outer wall of the mounting rod 2021, and a screw 2024 fixedly mounted on one side of the mounting rod 2021. An adjusting cap 2025 is threadedly connected to the outer wall of the screw 2024. The mounting rod 2021... A spring 2026 is fitted onto the outer wall of the device, positioned between the friction plate 2023 and the adjusting cap 2025. A mounting rod 2021 passes through both sets of adjusting arms, serving as the rotation axis for the arms. The adjusting cap 2025 compresses the spring 2026, which in turn compresses the friction plate 2023 towards the fixed plate 2022. This, in turn, compresses the two sets of adjusting arms through the fixed plate 2022 and the friction plate 2023, creating resistance during rotation. The screw 2024 and the adjusting cap 2025 allow the operator to adjust the resistance by rotating the adjusting cap 2025. Appropriate resistance provides tactile feedback to the user. This allows users to know they are making effective adjustments, rather than just randomly sliding, which helps to control the phone's position and angle more precisely. The second adjustment arm 204, the third adjustment arm 205, the fourth adjustment arm 206, and the fifth adjustment arm 207 all have weight-reduction grooves 210 inside. The installation plate 201 reduces the weight of the second adjustment arm 204, the third adjustment arm 205, the fourth adjustment arm 206, and the fifth adjustment arm 207, improving the user experience. A cable clip 211 is fixedly installed on one side of the second adjustment arm 204, the third adjustment arm 205, the fourth adjustment arm 206, and the fifth adjustment arm 207. When charging the phone, the charging cable can be fixed to one side of the bracket mechanism 2 through the cable clip 211 to ensure the neatness of the cable.

[0023] The specific implementation method is as follows: a multi-segment adjustable support arm is formed by the cooperation between several damping adjustment mechanisms 202 and the second adjustment arm 204, the third adjustment arm 205, the fourth adjustment arm 206, and the fifth adjustment arm 207. The multi-segment adjustable support arm can be rotated and its orientation can be changed arbitrarily by the cooperation between the first adjustment arm 203 and the damping adjustment mechanism 202. The magnetic suction cup 209 can flexibly change its orientation at one end of the fifth adjustment arm 207 by the damping ball joint 208. Then, the magnetic suction cup 209 can be used to attach electronic devices such as mobile phones or tablets, so that people can fix their mobile phones to one end of the support mechanism 2 and flexibly change their position. Users no longer need to hold their mobile phones, which improves the comfort of the multi-functional folding sofa bed.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a multifunctional folding sofa bed, wherein the lifting mechanism 4 includes a mounting frame 401, which is fixedly installed inside the mounting slot 3. A motor 402 is fixedly installed on one side of the mounting frame 401, and a lead screw 405 is fixedly connected to one side of the output shaft of the motor 402 via a coupling. The lead screw 405 is rotatably installed inside the mounting frame 401, and a limit rod 403 is fixedly installed inside the mounting frame 401. A slider 404 is slidably installed on the outer wall of the limit rod 403, and the slider 404 is fixedly installed on one side of the support mechanism 2. Several USB ports 6 are provided on the top of the mounting slot 3, which facilitate users to charge the device. A storage cover 5 is rotatably installed on the top of the mounting slot 3. The storage cover 5 can cover the top of the mounting slot 3 when the support mechanism 2 is in the folded state, ensuring the overall aesthetics of the sofa bed body 1.

[0025] The specific implementation method is as follows: the cooperation between the mounting bracket 401, the limiting rod 403, the slider 404, and the lead screw 405 enables the motor 402 to drive the support mechanism 2 to move up and down inside the mounting groove 3 when it is running, so that the support mechanism 2 can be put into the mounting groove 3 when the personnel are not using the support mechanism 2, and prevent the exposed support mechanism 2 from affecting the user experience.

[0026] Working principle: When using this multi-functional folding sofa bed, multiple adjustable support arms are formed by the cooperation between several damping adjustment mechanisms 202 and the second adjustment arm 204, the third adjustment arm 205, the fourth adjustment arm 206, and the fifth adjustment arm 207. The cooperation between the first adjustment arm 203 and the damping adjustment mechanism 202 allows the multiple adjustable support arms to rotate and change their orientation at will. The damping ball joint 208 allows the magnetic suction cup 209 to flexibly change its orientation at one end of the fifth adjustment arm 207. Furthermore, the magnetic suction cup 209 can attract electronic devices such as mobile phones or tablets, allowing users to fix their mobile phones to one end of the support mechanism 2 and flexibly change their position, eliminating the need for users to hold their mobile phones and improving the comfort of the multi-functional folding sofa bed.

[0027] The mounting rod 2021 passes through the two sets of adjusting arms as the rotation axis of the adjusting arms. The adjusting cap 2025 compresses the spring 2026, and the spring 2026 then compresses the friction plate 2023 towards the side closer to the fixed plate 2022. In turn, the fixed plate 2022 and the friction plate 2023 compress the two sets of adjusting arms, so that the two sets of adjusting arms require a certain resistance when rotating. Through the cooperation between the screw 2024 and the adjusting cap 2025, the operator can change the resistance required for the two sets of adjusting arms to rotate by rotating the adjusting cap 2025. Appropriate resistance can provide the user with operational feedback, letting the user know that they are making effective adjustments rather than sliding randomly. This helps to control the position and angle of the phone more precisely.

[0028] The installation plate 201 reduces the weight of the second adjusting arm 204, the third adjusting arm 205, the fourth adjusting arm 206, and the fifth adjusting arm 207, improving the user experience. When charging a mobile phone, the user can fix the charging cable to one side of the bracket mechanism 2 with the cable clip 211 to ensure the neatness of the cable.

[0029] The cooperation between the mounting bracket 401, the limiting rod 403, the slider 404, and the lead screw 405 allows the motor 402 to drive the support mechanism 2 to move up and down inside the mounting slot 3 when it is running. This allows the support mechanism 2 to be retracted into the mounting slot 3 when not in use, preventing the exposed support mechanism 2 from affecting the user experience.

[0030] The USB interface 6 allows users to easily charge the device, and the storage cover 5 can cover the top of the mounting slot 3 when the support mechanism 2 is in its stored state, ensuring the overall aesthetics of the sofa bed body 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
