[0047] 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. Example

[0048] See Figures 1 to 5As shown, a smart arm structure includes a base 1, a lifting structure 2 mounted on the base, a horizontal rotating structure 3 fixed to the top of the lifting structure, and an inclined angle support arm structure 4 mounted on the top of the horizontal rotating structure. In this embodiment, the base is either a panel base or a clamping base. A panel base allows for direct placement on a horizontal surface, while a clamping base allows for clamping and fixing to a table edge or other location. The choice depends on the needs. The base is a conventional structure in the prior art, and the bottom end of the lifting structure can be directly fixed to the base with screws or rotatably adjustable with bolts.

[0049] In this embodiment, the lifting structure includes a hollow support tube 21, a lifting rod 22, a main control seat 23, a lifting drive structure 24, and a lifting base 25. The main control seat is mainly used to install the control structure, and a control circuit board and power cord are fixed inside the main control seat. The control circuit board is a conventional structure of the prior art and can be controlled by a switch or by remote control. The lifting rod can be adjusted up and down inside the hollow support tube to ensure the effectiveness of the lifting.

[0051] In this embodiment, the lifting drive structure 24 includes a first drive motor 241, a drive conveyor belt 242, and a sliding shaft 243. The first drive motor is used in conjunction with the drive conveyor belt to ensure the effectiveness and stability of the lifting.

[0052] During assembly, the first drive motor is fixed inside the base, and a drive wheel is fixed on the main shaft of the first drive motor. The sliding shaft is located in the upper part of the inner cavity of the hollow support tube, and an auxiliary wheel is provided on the sliding shaft. The drive conveyor belt is arranged in a racetrack shape between the drive wheel and the auxiliary wheel. The lifting seat is fixed on the drive conveyor belt. The first drive motor is connected to the control circuit board and the power cord. The first drive motor drives the lifting seat to rise and fall inside the hollow support tube through the drive conveyor belt. The lifting seat can be fixed to the drive conveyor belt by screws or other conventional methods such as clamping.

[0053] In this embodiment, the drive conveyor belt is a toothed belt, the drive pulley is a drive gear, and the drive gear meshes with the toothed belt. Using a toothed belt in conjunction with a drive gear improves the smoothness and efficiency of the transmission.

[0054] Furthermore, in this embodiment, the horizontal rotation structure includes a fixed base 31, a second drive motor 32, a power-collecting ring 33, a power-collecting contact 34, and a connecting base 35. The power-collecting ring, in conjunction with the power-collecting contact, ensures stable and effective power collection during rotation, preventing wire tangling. During assembly, the fixed base is fixed to the top of the lifting support rod, the second drive motor is fixed inside the fixed base, and the connecting base is fixed to the main shaft of the second drive motor. When the power-collecting ring is fixed to the fixed base, the power-collecting contact is fixed to the connecting base; when the power-collecting ring is fixed to the connecting base, the power-collecting contact is fixed to the fixed base. When the fixed base and the connecting base rotate relative to each other, the power-collecting contact is electrically connected to the power-collecting ring. The power-collecting ring or the power-collecting contact is connected to the control circuit board and the power cord. This improves the convenience and effectiveness of the connection.

[0055] In this embodiment, the tilting support arm structure includes a connecting frame 41, a third drive motor 42, a drive transverse shaft 43, a conductive ring 44, a conductive spring 45, and a support arm body 46.

The drive transverse shaft is fixed to the main shaft of the third drive motor, and the bottom end of the support arm body is fixed to the drive transverse shaft. The power extraction ring is fixed to the connecting frame, and the conductive spring is fixed to the side of the support arm body. The conductive spring is electrically connected to the power extraction ring. Both the third drive motor and the power extraction ring are electrically connected to the power extraction contact. Furthermore, the rotation of the third drive motor drives the support arm body to achieve tilt angle adjustment. The rotation of the third drive motor drives the drive transverse shaft to rotate, and the drive transverse shaft drives the support arm body to achieve tilt angle adjustment.

[0056] Furthermore, in practical applications, a lamp holder 9 or a hand clamp 10 is fixed on the support arm, and the lamp holder or hand clamp is electrically connected to the conductive spring. In this embodiment, a hand clamp is fixed on the support arm for holding a mobile phone or other common electrical appliances. This is a conventional structure in the prior art, so it is not described in detail, but simply applied. The hand clamp includes a base cylinder 101, a rack 102 that can be stretched and disposed in the base cylinder, and a spring 103 is fixed between the rack 102 and the base cylinder. Clamping pieces 104 are fixed on the upper part of the base cylinder and the top of the rack 102, respectively. A latch 105, a latch elastic element 106, and a button 107 are fixed on the top of the base cylinder. The rack 105 extends and retracts in the base cylinder and is limited by the latch. A power interface 108 and a power-taking pin 109 are fixed at the bottom of the base cylinder. In this embodiment, the power interface is a TYPE-C interface. In practical applications, other conventional power interfaces can also be used. The power-taking pin is electrically connected to the conductive spring. When placing mobile phones or other electronic devices, pull the rack rod upwards, and the spring force will cause the clip to clamp onto the phone for positioning. The latch is engaged at the upper limit of the rack rod by the action of the latch elastic element. When a button is pressed, the latch separates from the rack rod, at which point the rack rod can move up and down within the base tube.

[0057] In this embodiment, to ensure the stability of the lifting position, sensors 5 are fixed on the hollow support tube, the fixed seat, and the connecting frame. Several magnets 6 are provided on the lifting rod, the connecting seat, and the support arm to cooperate with the sensors and for sensing and limiting the movement. The sensors are connected to the control circuit board. The sensors can sense the position of the magnets and limit their movement. During lifting or rotation, the magnets will lift or rotate synchronously. When the sensor senses one of the magnets, it senses its position and limits its movement. Multiple magnets can be used for sensing and limiting at different positions to meet different usage requirements.

[0058] Furthermore, in this embodiment, a conductive track plate 7 connected to the control circuit board inside the main control seat is fixed inside the hollow support tube; a conductive pin 8 electrically connected to the conductive track plate is fixed on the side of the lifting seat, and the conductive pin is electrically connected to the second drive motor and the power take-up ring. This can improve the effectiveness of conductivity and facilitate the power supply connection of the first drive motor. In this embodiment, the voltage on the conductive track plate and the conductive pin is a low-voltage safety voltage, and the effectiveness and reliability of conductivity can be ensured during lifting by the conductive pin in conjunction with the conductive track plate.
