[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a chair with retractable armrests, comprising a seat body 1, an active lifting armrest 2 and a driven lifting armrest 8. The driven lifting armrest 8 is provided on one side of the seat body 1, and the other side of the seat body 1 is connected with the active lifting armrest 2 through a lifting structure. The active lifting armrest 2 and the driven lifting armrest 8 are connected through a connecting rod 6. Through the setting of the connecting rod 6, the lifting of the active lifting armrest 2 can drive the lifting of the driven lifting armrest 8.

[0023] The active lifting armrest 2 and the driven lifting armrest 8 have the same size, and both the active lifting armrest 2 and the driven lifting armrest 8 are T-shaped structures. Both ends of the seat body 1 are fixedly connected to the limit plate 3, and a through hole is provided in the middle of the limit plate 3. The vertical end of the active lifting armrest 2 or the driven lifting armrest 8 is movably connected to the limit plate 3 through the through hole. The utility model uses the limit plate 3 to limit the vertical end of the active lifting armrest 2 or the vertical end of the driven lifting armrest 8, so that the active lifting armrest 2 and the driven lifting armrest 8 can only move in the vertical direction; the width value of the limit plate 3 is the same as the width value of the horizontal end of the active lifting armrest 2; the outer side of the limit plate 3 is flush with the outer side of the horizontal end of the active lifting armrest 2; the distance value between the top of the limit plate 3 and the top of the seat plate of the seat body 1 is not less than the thickness value of the horizontal end of the active lifting armrest 2. With this arrangement, the active lifting armrest 2 and the driven lifting armrest 8 can be moved to the bottom of the seat plate of the seat body 1, so that the seat becomes an armrest-free state, thereby improving the adaptability of the seat.

[0024] In some embodiments of the present application, the lifting structure includes a rotating motor 9 fixedly connected to the seat body 1 through a connecting plate 12 and a screw 5 fixedly connected to the end of the output shaft of the rotating motor 9. The connecting plate 12 is L-shaped, and the top of the vertical end of the connecting plate 12 is fixedly connected to the bottom of the seat body 1. The rotating motor 9 is fixed on the horizontal end of the connecting plate 12. The bottom end of the screw 5 is movably connected to the horizontal end of the connecting plate 12. A threaded hole matching the screw 5 is provided in the middle of the vertical end of the active lifting armrest 2, and the screw 5 is located below the limit plate 3. Through the setting of the lifting structure, the rotation of the rotating motor 9 can drive the screw 5 fixedly connected to it to rotate. When the screw 5 rotates, the active lifting armrest 2 threadedly connected to the screw 5 can move in the direction where the screw 5 is located, that is, when the rotating motor 9 is working, the height of the active lifting armrest 2 can change.

[0025] An accommodating groove 2 is provided at one end of the active lifting armrest 2 away from the seat back, and a switch button 4 is provided in the inner cavity of the accommodating groove 2. The user can use the switch button 4 to control the forward and reverse rotation of the rotating motor 9, thereby making the active lifting armrest 2 rise or fall; through the setting of the accommodating groove 2, the user can put his arm on the active lifting armrest 2 without accidentally touching the switch button 4, which facilitates the use of the seat.

[0026] A groove is provided in the middle of the horizontal ends of the active lifting armrest 2 and the driven lifting armrest 8. The inner cavity of the groove is connected to the extended armrest 7 through an electric push rod 11, and one end of the electric push rod 11 is fixedly connected to the inner side of the inner cavity of the groove, and the other end of the electric push rod 11 is fixedly connected to the extended armrest 7, and the extended armrest 7 is movably connected to the outer side of the inner cavity of the groove. Through the setting of the electric push rod 11, the extension and retraction of the electric push rod 11 can change the position of the extended armrest 7 in the groove, thereby changing the armrest length of the seat.

[0027] A receiving groove 1 is provided in the middle of one end of the extended armrest 7 away from the electric push rod 11, and a switch button 2 10 is located in the inner cavity of the receiving groove 1. Through the setting of the switch button 2 10, the user can control the extension or contraction of the electric push rod 11 by pressing the switch button 2 10, thereby changing the length of the armrest of the chair. Through the setting of the receiving groove 1, the user is prevented from accidentally touching the switch button 2 10 when using the armrest.

[0028] From the above description, it can be seen that during the use of the chair, the length of the armrests in the chair can be changed, so that the armrests of the chair can adapt to arms of various lengths, thereby improving the comfort and adaptability of the chair when used; the height of the armrests of the chair can be adjusted according to needs; and during the process of adjusting the height or length of the armrests, the user can experience the height or length of the armrests in real time, so that the user can quickly adjust the height or length of the armrests to suit his or her size.

[0029] The outer surface of the extended armrest 7 is wrapped with a telescopic pad. In some embodiments of the present application, the telescopic pad is made of sponge. It is configured so that when the extended armrest 7 is pulled out, the telescopic pad expands, eliminating the distance between the extended armrest 7 and the top of the active lifting armrest 2 or the driven lifting armrest 8, thereby improving the comfort of the seat armrest when in use.

[0030] Note: The electricity required for the seat in this application can be provided by market electricity or sockets; at the same time, the switch is connected to the circuit board, and the circuit board can be connected to the electrical components, thereby controlling the operation of the electrical components in the seat. The specific control does not belong to the technical improvement part of this application, and it is the existing technology and will not be elaborated.

[0031] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0032] To sum up: when the chair with retractable armrests is in use and the height of the armrests needs to be adjusted, the user presses the switch button 4 to turn the rotating motor 9 on, which drives the screw 5 fixedly connected thereto to rotate. When the screw 5 rotates, the height of the active lifting armrest 2 changes, the restriction on the switch button 4 is released, the rotating motor 9 is off, and the height of the active lifting armrest 2 is fixed.

[0033] When the user needs to adjust the length of the armrest of the chair, the user presses the switch button 2 10, and the electric push rod 11 drives the extended armrest 7 to move, and the length of the armrest of the chair changes, so that the chair can adapt to various needs.

[0034] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
