DETAILED DESCRIPTION

[0018] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] First embodiment

[0020] See also Figures 1 and 2 , Figure 1 This is a structural diagram of an adjustable office chair according to the first embodiment of the present invention. Figure 2 It is a cross-sectional schematic diagram of an adjustable office chair according to the first embodiment of the present utility model.

[0021] The present invention provides an adjustable office chair comprising a base 101, a telescopic support rod 102, and an adjustment assembly 103. The adjustment assembly 103 includes a backrest 104, a seat plate 105, an air pump 106, a rotating mechanism 107, an inflatable cushion 108, a headrest 110, a slide 111, a slider 112, a motor 113, a rotating rod 114, a bracket 115, a curved plate 116, a hand guard 117, a battery 118, and a protective shell 119. The aforementioned solution solves the problem of existing devices in which the headrest 110 and waist position cannot be adjusted according to the user's needs during use, resulting in low comfort.

[0022] In this embodiment, the base 101 is a supporting structure that contacts a placement surface when the chair is in use.

[0023] Among them, the seat plate 105 is connected to the telescopic support rod 102 and is located at the top of the telescopic support rod 102, the rotating mechanism 107 is connected to the seat plate 105 and is located on one side of the seat plate 105, the chair back 104 is connected to the rotating mechanism 107 and is located on one side of the rotating mechanism 107, the inflatable cushion 108 is fixedly connected to the chair back 104 and is located on one side of the chair back 104, the slide 111 is fixedly connected to the chair back 104 and is located on the inner side of the chair back 104, the slider 112 is slidably connected to the slide 111 and is located on one side of the slide 111, the headrest 110 is fixedly connected to the slider 112 and is located on one side of the slider 112, the air pump 106 is connected to the seat plate 105 It is fixedly connected and located at the bottom of the seat plate 105. The inflatable cushion 108 is connected to the air pump 106. The telescopic support rod 102 can adjust the height of the chair. The inflatable cushion 108 is inflated by the air pump 106 to change the softness, hardness and size of the inflatable cushion 108. The headrest 110 changes its position by sliding inside the slide groove 111 through the slider 112. The sliding resistance between the slider 112 and the slide groove 111 is large, which prevents the headrest 110 from sliding naturally after adjustment. The rotating mechanism 107 can adjust the angle between the chair back 104 and the seat plate 105, which solves the problem that the headrest 110 and the waist position cannot be adjusted according to the user's needs during use of the existing device, resulting in low comfort of the device.

[0024] Secondly, the rotating mechanism 107 includes a motor 113 and a rotating rod 114. The motor 113 is fixedly connected to the seat plate 105 and is located on the inner side of the seat plate 105. The rotating rod 114 is fixedly connected to the output end of the motor 113 and is located on one side of the motor 113. The chair back 104 is fixedly connected to the rotating rod 114 and is located on one side of the rotating rod 114. The motor 113 drives the rotating rod 114 to rotate, so that the chair back 104 rotates following the rotating rod 114. The motor 113 is brakeable.

[0025] Again, the adjustment assembly 103 also includes a bracket 115, a curved plate 116 and an arm guard 117. The bracket 115 is fixedly connected to the seat plate 105 and is located at the top of the seat plate 105. The curved plate 116 is fixedly connected to the bracket 115 and is located on one side of the bracket 115. The arm guard 117 is slidably connected to the curved plate 116 and is fixedly connected to the chair back 104 and is located on one side of the curved plate 116. The bracket 115 is used to support and install the curved plate 116. The arm guard 117 slides on the curved plate 116 when the chair back 104 rotates. The arm guard 117 and the curved plate 116 adopt an arc design, so that the arm guard 117 can slide during the rotation of the chair back 104.

[0026] Finally, the adjustment component 103 also includes a battery 118 and a protective shell 119. The battery 118 is fixedly connected to the chair back 104 and is located on one side of the chair back 104. The protective shell 119 is fixedly connected to the chair back 104 and is located on the outside of the battery 118. The battery 118 is used to provide a mobile power source for the device, and the protective shell 119 is used to protect the battery 118. Ventilation holes and a charging port are provided on the protective shell 119.

[0027] When using an adjustable office chair of the present invention, the base 101 is a supporting device structure that contacts the placement surface when the chair is in use. The telescopic support rod 102 can adjust the height of the chair. The inflatable cushion 108 is inflated by the air pump 106 to change the softness, hardness and size of the inflatable cushion 108. The headrest 110 changes its position by sliding inside the slide groove 111 through the slider 112. The sliding resistance between the slider 112 and the slide groove 111 is large, which prevents the headrest 110 from sliding naturally after adjustment. The rotating mechanism 107 can adjust the angle between the chair back 104 and the seat plate 105, which solves the problem that the headrest 110 and the waist position of the existing device cannot be adjusted according to the user's needs during use, resulting in low comfort of the device.

[0028] Second embodiment

[0029] See also Figure 3 , Figure 3 FIG2 is a cross-sectional view of an adjustable office chair according to a second embodiment of the present invention. Based on the first embodiment, the adjustable office chair according to the present invention further includes:

[0030] The adjustment component 103 also includes a fan 201 and a breathable layer 202. The breathable layer 202 is fixedly connected to the chair back 104 and is located on the outside of the chair back 104. The fan 201 is fixedly connected to the chair back 104 and is located on the inside of the chair back 104. The fan 201 can be used to blow air or ventilate the user's back. The breathable layer 202 covers the appearance structure of the fan 201, thereby increasing the aesthetics of the device while ensuring ventilation.

[0031] The above disclosure is only a preferred embodiment of the adjustable office chair of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. Ordinary technicians in this field can understand that implementing all or part of the processes of the above embodiment and making equivalent changes in accordance with the claims of the present invention still fall within the scope of the utility model.
