Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to an office chair that can move intelligently. Background Technique

[0002] An office chair refers to various chairs equipped for work convenience in daily work and social activities. Office chairs are divided into narrow sense and broad sense. The office chair in the narrow sense refers to the backrest chair that people sit on when working on the desktop in a sitting position, and the office chair in the broad sense refers to all chairs used in the office, including executive chairs, medium-sized chairs, guest chairs, staff chairs, meeting chairs, visitor chairs, training chairs, etc.

[0003] Most office chairs on the market are composed of a seat board, chair legs, a backrest, and armrests. For some office workers whose main skill requirement is typing, when working, they often manually move the office chair closer to the desk, adjust to a comfortable position, and perform text input work. However, due to the certain weight of the office chair, the way of manually moving the office chair is relatively laborious; and when the office worker needs to get up and move, they apply pressure with their legs to push the office chair backward. This process not only causes harm to the legs, but also, if the operation is not careful, may cause the office worker to fall backward due to unstable center of gravity, further causing harm to the office worker. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides an office chair that can move intelligently, which is used to solve the technical problems mentioned in the background technique, that is, some office chairs have a certain weight, and the way of manually moving the office chair is relatively laborious; and when the office worker needs to get up and move, they apply pressure with their legs to push the office chair backward. This process not only causes harm to the legs, but also, if the operation is not careful, may cause the office worker to fall backward due to unstable center of gravity, further causing harm to the office worker.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] An office chair that can move intelligently includes a seat board, two legs connected to the bottom of the seat board, and also includes a base. A bottom plate is fixedly arranged on the top surface of the base, and two slide rails are fixedly arranged on both sides of the top surface of the base. A motor is arranged on the bottom plate, the output end of the motor is connected with a transmission shaft, a slide block is sleeved on the transmission shaft in a threaded manner, the bottom surface of the slide block abuts against the top surface of the bottom plate and is slidably arranged on the top surface of the bottom plate. The two legs are slidably arranged in the two slide rails, and a connecting rod is fixedly arranged between the two legs, and the connecting rod passes through the slide block.

[0007] Working Principle:

[0008] When an office worker needs to move the position of the office chair, the motor is started. The output end of the motor drives the transmission shaft to rotate, the rotation of the transmission shaft drives the slider to move, and the movement of the slider drives the connecting rod, two supporting feet, and the seat plate to move, so that the office chair is moved to a suitable position.

[0009] Beneficial effects:

[0010] In this solution, by setting the bottom plate, two slide rails, a motor, a transmission shaft, a slider, and a connecting rod, starting the motor drives the office chair to approach or move away from the desk, achieving the purpose of automatic movement, with simple and effortless operation.

[0012] Figure 2 is Figure 1 A schematic structural diagram with the protective cover removed.

[0013] In the above drawings: seat plate 1, supporting feet 2, horizontal part 201, inclined part 202, bottom plate 3, motor 4, transmission shaft 5, slider 6, connecting rod 7, slide rail 8, mounting rod 9, gas rod 10, support sleeve block 11, base 12, strengthening block 13, support rod 14, protective cover 15, strip-shaped hole 16. Specific implementation manners

[0014] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0015] Embodiment:

[0016] As Figure 2 shown, an intelligent movable office chair includes a seat plate 1 and two supporting feet 2 connected to the bottom of the seat plate 1. It further includes a base 12. A bottom plate 3 is fixedly provided on the top surface of the base 12, and two slide rails 8 are fixedly provided on both sides of the top surface of the base 12. A motor 4 is provided on the bottom plate 3. The output end of the motor 4 is connected to a transmission shaft 5. A slider 6 is sleeved on the transmission shaft 5 by a thread. The bottom surface of the slider 6 abuts against the top surface of the bottom plate 3 and is slidably provided on the top surface of the bottom plate 3. The two supporting feet 2 are slidably provided in the two slide rails 8. A connecting rod 7 is fixedly provided between the two supporting feet 2. The connecting rod 7 fixedly passes through the slider 6. By setting the bottom plate 3, two slide rails 8, a motor 4, a transmission shaft 5, a slider 6, and a connecting rod 7, starting the motor 4 drives the office chair to approach or move away from the desk, achieving the purpose of automatic movement, with simple and effortless operation.

[0017] As Figure 1 and 2As shown, each of the feet 2 is composed of a horizontal part 201 and two inclined parts 202. An installation rod 9 is fixedly provided between one of the inclined parts 202 of each foot 2 away from the motor 4 and the horizontal part 201. An air rod 10 is fixedly provided on the installation rod 9. A support sleeve block 11 is fixedly connected to the telescopic end of the air rod 10. The support sleeve block 11 and the slide rail 8 are on the same side of the foot 2; the horizontal part 201 is slidably arranged in the slide rail 8. The support sleeve block 11 is of a hollow structure and has an opening on the side facing the foot 2. The support sleeve block 11 covers the outer periphery of the foot 2. The connection part of the horizontal part 201 of each foot 2 and the two inclined parts 202 is arc-shaped, and the structure of the support sleeve block 11 is consistent with this arc-shaped structure. The materials of the foot 2 and the support sleeve block 11 are both stainless steel, having good corrosion resistance and relatively high hardness.

[0018] Place the base 12 on the ground. When the office chair moves away from the end of the slide rail 8 close to the motor 4, the part of the foot 2 that disengages from the slide rail 8 has a height difference from the base 12 because it loses the support of the slide rail 8. Therefore, by setting the installation rod 9, the air rod 10, and the support sleeve block 11, start the air rod 10 to push the support sleeve block 11 to move towards the base 12 and abut against the base 12 or the ground, so as to provide support for this part of the foot 2; and when the office chair is moving, the support sleeve block 11 will rub against the base 12 or the ground, which is likely to cause wear of the support sleeve block 11. By starting the air rod 10 to drive the support sleeve block 11 to fit with the outer periphery of the foot 2, it is possible to prevent the support sleeve block 11 from contacting the base 12 or the ground during the movement of the office chair.

[0019] As Figure 1 and 2 As shown, the telescopic end of the air rod 10 is fixedly connected to one side of the support sleeve block 11. A support rod 14 is fixedly connected to the other side of the support sleeve block 11. The support rod 14 is parallel to the telescopic end of the air rod 10. A reinforcing block 13 is fixedly provided between the support rod 14 and the telescopic end of the air rod 10. The materials of the support rod 14 and the reinforcing block 13 are both stainless steel, having good corrosion resistance and relatively high hardness. The reinforcing block 13 and the support rod 14 play a strengthening role in the support sleeve block 11 for propping up the foot 2.

[0020] As Figure 1 As shown, a protective cover 15 is sleeved outside the bottom plate 3. The motor 4, the transmission shaft 5, and the slider 6 are all covered in the protective cover 15. Two strip-shaped holes 16 are opened on both sides of the protective cover 15. The connecting rod 7 is slidably arranged in the two strip-shaped holes 16 on both sides of the protective cover 15. The protective cover 15 can prevent the transmission shaft 5 from being exposed outside and getting the user's trouser legs, shoelaces, etc. caught in it, avoiding potential safety hazards.

[0021] Working principle:

[0022] When an office worker needs to move the office chair closer to the desk, the motor 4 is started. The output end of the motor 4 drives the transmission shaft 5 to rotate. The rotation of the transmission shaft 5 drives the slider 6 to move. The movement of the slider 6 drives the connecting rod 7, the two feet 2, and the seat board 1 to move, so that the office chair moves to a suitable position;

[0023] Then the air rod 10 is started. The telescopic end of the air rod 10 extends, driving the reinforcement block 13, the support rod 14, and the support sleeve block 11 to move towards the base 12, and making the support sleeve block 11 abut against the base 12 or the ground. Thus, the whole operation is completed.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
