Description

Technical Field

[0001] The invention belongs to the technical field of children's learning chairs, and in particular relates to a method for using a children's learning chair with an electric lifting structure. Background Art

[0002] As people pay more attention to children's health and comfort, various ergonomic learning chairs have appeared on the market, aiming to help children maintain a correct sitting posture by adjusting the height and angle of the seat. However, the height adjustment of most existing learning chairs still relies on manual adjustment, which generally uses pneumatic rods or mechanical gears to adjust the height. This type of structure meets some market needs in terms of functionality and application scope, but there is still a lot of room for improvement in terms of precise adjustment, stability, safety, etc., which cannot meet the needs of children for fast and precise height adjustment, and lacks a complete safety design. For example: 1. Poor lifting stability. The existing electric lifting system is prone to shaking or instability during the lifting process, resulting in a poor experience for children when using it; 2. Lack of safety. Some lifting systems lack anti-pinch design, and there is a potential risk of children's fingers being pinched during operation; 3. Insufficient lifting accuracy. The existing technology is difficult to achieve precise height adjustment. Usually, only limited height settings can be made, which cannot meet the delicate needs of children at different height stages; 4. Complex operation. The lifting control panel of some designs is not intuitive enough, and it is difficult for children to adjust it by themselves when using it. Summary of the invention

Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0034] like Figure 1-7 As shown, a method for using a children's learning chair with an electric lifting structure is used. The method uses a children's learning chair with an electric lifting structure. The children's learning chair includes a seat component, a guide rail lifting component, and a control component; the seat component includes a base 4, a seat 6 is provided above the base 4, armrests 1 are provided on both sides of the seat 6, and a backrest 8 is provided on the rear side of the seat 6; the guide rail lifting component includes a lifting column 13, the lifting column 13 is arranged between the base 4 and the seat 6, and an anti-pinch device is provided on one side of the lifting column 13; the control component includes a control panel 2, the control panel 2 is connected to the electric motor 15 of the lifting column 13, the control panel 2 is provided with a control button 19, and the control button 19 includes an up button 20, a down button 21 and at least one fixed height up button 22; during use, the operating speed and direction of the electric motor 15 of the lifting column 13 are controlled by pressing the control button 19 on the control panel 2, so that the seat 6 is driven to rise and fall through the lifting column 13. This design is easy to operate and has precise adjustment. Through the coordinated work of the seat components, guide rail lifting components and control components, the stability of the children's learning chair during the lifting process is guaranteed, and precise height adjustment can be achieved. It can also detect abnormal situations during the lifting process to ensure the safety of children's use, thereby ensuring that children of different ages can maintain a good sitting posture when using it.

[0035] When the children's learning chair is in use, after pressing the fixed height raising button 22, the seat 6 is raised or lowered to a preset height, and then the height of the seat 6 is adjusted again by pressing the raising button 20 or the lowering button 21, so that the child can quickly adjust the seat 6 to a suitable height.

[0036] In order to facilitate the movement of the children's learning chair, casters 3 are provided below the base 4. In addition, the casters 3 can be universal wheels.

[0037] The control panel 2 is arranged on the seat 6. Alternatively, the control panel 2 is arranged on the armrest 1, so that it is convenient for children to control the lifting of the seat 6 through the control panel 2.

[0038] In order to ensure the use effect of the children's learning chair, the seat component includes a seat support frame compatible with the guide rail lifting component, the seat support frame includes a seat bracket 9 arranged under the seat 6, the lower part of the seat bracket 9 is provided with a connecting rod 10 for connecting to the upper part of the lifting column 13, and the rear side of the seat bracket 9 is provided with a backrest support rod 7 for connecting to the backrest 8; a decorative box 5 is provided above the base 4, and a sleeve 14 is provided in the decorative box 5. The sleeve 14 is sleeved on the outside of the lifting column 13, and the upper part of the decorative box 5 is provided with an opening for extending the sleeve 14. This design ensures the stable lifting of the children's learning chair through the cooperation of structures such as the seat bracket 9 and the backrest support rod 7, and also reduces the exposure of the lifting column 13 through components such as the decorative box 5 and the sleeve 14, thereby improving the safety of the children's learning chair.

[0039] A magnetic sensor 16 for detecting the lifting height of the seat 6 is provided on the lifting column 13, and a magnet compatible with the magnetic sensor 16 is fixed on the sleeve 14.

The anti-pinch device includes a spring plunger 17 arranged on one side of the connecting joint 12. A limiting groove 18 adapted to the spring plunger 17 is provided on the sleeve 14, so that mechanical limiting is achieved through the cooperation between the spring plunger 17 and the limiting groove 18, thereby preventing the seat 6 from being excessively lifted or lowered. When the seat 6 is lifted or lowered to the extreme position, the limiting device will block the lifting process of the lifting column 13 to prevent further movement.

[0042] The guide rail lifting component adopts a double guide rail lifting device, which includes two first lifting columns arranged in front and back; there are two connecting rods 10, and one of the two connecting rods 10 is located below the backrest support rod 7. The double guide rail lifting device can ensure the stability of the seat 6 during the lifting process, making the entire lifting process smooth and stable. Alternatively, the guide rail lifting component adopts a single guide rail lifting device, which includes a second lifting column; a connecting rod 10 is provided below the seat bracket 9 near the backrest support rod 7, so as to reduce the production cost through the single guide rail lifting device.
