The upper part of armrest I has a storage cavity with its opening located on the upper surface of the armrest. Inside the storage cavity are a resiliently concealed table and a folding support. The folding support includes a primary folding arm and a secondary folding arm. The secondary folding arm is fixedly connected to the inner wall or bottom of the storage cavity, and the primary folding arm is located inside the secondary folding arm and slidably connected. A slider on the table is slidably connected to the primary folding arm. The upper surface of the table has a flip-up and rotatable mobile phone holder. The mobile phone holder includes a support base rotatably connected to the table. A telescopic support is rotatably connected to the support base. A clamp is provided on the telescopic support. The table has a recess for holding the mobile phone holder when folded and closed.

[0006] The slider has two disc-shaped ends, and the inner side of the first-stage folding arm is provided with a groove. The two ends of the slider are locked in the groove and slide up and down. The second-stage folding arm fits against the outer side of the first-stage folding arm and is provided with corresponding limiting protrusions and grooves.

[0007] The primary and secondary folding arms are made of aluminum alloy.

[0008] The tabletop is equipped with cup slots and pen slots.

[0009] The end of the table is provided with a vertical bend, which closes the opening of the storage cavity of the armrest I after being stored and closed.

[0010] The bottom of the storage cavity is equipped with a rebound device corresponding to the tabletop; and a hollowed-out opening that connects to the outside.

[0011] The inside of the handrail II is equipped with a storage bag and a tissue box.

[0012] The sliders are longer than 10cm and are arranged in a centrally located group; the sliders are shorter than 3cm and are arranged in two groups, along with a first-level folding arm and a second-level folding arm.

[0013] The backrest body is equipped with a headrest, and the armrests or table are equipped with wireless charging and USB charging ports. The power cord extends from the rear of the backrest body and has a power plug.

[0014] The present utility model application has the following beneficial effects: 1. Space efficiency: The overall thickness after folding is ≤5cm, completely hidden inside the armrest; 2. Ease of use: Unfolding / folding can be completed within 10 seconds with one hand; 3. Multi-scene adaptation: The table unfolds to a size of 30×40cm and can bear a weight of over 3kg; 4. Functional integration: Integrates equipment support, item placement, and storage functions. Attached Figure Description

[0017] Example 1

[0018] according to Figure 1-7 A multifunctional backrest device integrating a folding storage table and a mobile phone holder includes a backrest body 1, armrests I2 and II3 on ​​both sides. The upper part of the armrest I has a storage cavity 202, the opening of which is located on the upper surface of the armrest. Inside the storage cavity, there is a resiliently concealed table 201 and a folding bracket. The folding bracket includes a primary folding arm 213 and a secondary folding arm 214. The secondary folding arm is fixedly connected to the inner wall or bottom of the storage cavity, and the primary folding arm is located inside the secondary folding arm and slidably connected. The table 201 has a slider 211 that is slidably connected to the primary folding arm. The upper surface of the table has a flip-up and rotatable mobile phone holder. The mobile phone holder includes a bracket base 207 that is rotatably connected to the table. The bracket base has a rotatably connected telescopic bracket 206. The telescopic bracket has a clamp 205. The table has a storage groove 203 corresponding to the folding and closing of the mobile phone holder.

[0019] The slider 211 has two disc-shaped ends, and the inner side of the first-stage folding arm 213 is provided with a groove, and the two ends of the slider slide up and down in the groove; the second-stage folding arm 214 fits against the outer side of the first-stage folding arm and is provided with corresponding limiting protrusions and grooves.

[0020] The primary and secondary folding arms are made of aluminum alloy.

[0021] The tabletop is provided with a cup slot 208 and a pen slot 210.

[0022] The end of the table is provided with a vertical bending part 204, which closes the opening of the storage cavity of the armrest I after being stored and closed.

[0023] The bottom of the storage cavity is equipped with a rebound device 212 corresponding to the tabletop; and a perforation that connects to the outside. The purpose of the perforation is to allow debris that falls into the gaps to fall out through the perforation, reducing the accumulation of debris.

[0024] The inner side of the handrail II is provided with a storage bag 301 and a tissue box 302.

[0025] The backrest body is equipped with a headrest 101, and the armrest or table is equipped with wireless charging and USB charging ports, with the power cord extending from the rear of the backrest body and having a power plug.

[0026] The support base and the telescopic support are rotatably connected by a rotating shaft 215, which is equipped with damping.

[0027] Example 2

[0028] This embodiment is basically the same as embodiment 1, except that the number of sliders is changed.

[0029] The sliders are longer than 10cm and are arranged in a centrally located group; the sliders are shorter than 3cm and are arranged in two groups, along with a first-level folding arm and a second-level folding arm.

[0030] Example 3

[0031] according to Figure 3 , 6 The phone holder rotates horizontally via the base 207 and the tabletop, and vertically via the pivot 215, allowing for multi-angle adjustment. After use, the telescopic bracket 206 is retracted and folded, then folded into the receiving groove 203 via the pivot 215, keeping the entire tabletop level.

[0032] The support base 207 is connected to the tabletop by a damping shaft.

[0033] Example 4

[0034] according to Figure 7 When opened, press the tabletop 201; the tabletop 201 is lifted by the rebounder 212; the user lifts the tabletop 201 vertically to the top by hand, and at the same time, the first-level folding arm 213 is also fully lifted, and the slider 211 moves to the top of the first-level folding arm 213; rotate the tabletop 201, and the slider 211 rotates around the top of the first-level folding arm 213, and the tabletop 201 becomes horizontal.

[0035] The armrest next to the storage compartment is made of ABS plastic. After the tabletop 201 is laid flat, one end is pressed on the armrest to bear the weight. The first-level folding arm 213 is fully lifted, which at the same time pulls the tabletop down to prevent it from sagging and keep it parallel.

[0036] Additionally, it should be noted that some components are existing technologies and will not be described in detail, such as the rebound device 212, which pops up when pressed and resets when pressed again. Existing technologies and common structures in this field will also not be described in detail, such as the limiting blocks at the ends of the primary folding arm 213 and the secondary folding arm 214 to prevent them from coming off; the wiring layout; and the internal keel of the backrest body.

[0037] The above embodiments are some of the embodiments. Simple modifications based on the above structure, such as changing the shape of the slider, changing the sliding method with the first-level folding arm 213 and the second-level folding arm 214, etc., still fall within the protection scope of this application.

[0038] This multi-functional backrest device can be placed in various places such as beds, sofas, and play mats, and can be used for office work, study, entertainment, etc. The table can be quickly put away and put away, making it very convenient to use.
