[0028] Figures 1 to 3 Figure 100 shows a chair 100 according to an embodiment of the present utility model. The chair 100 includes a base structure 101 and a decorative member 103. At least a part of the decorative member 103 is exposed outside the base structure 101, so that the decorative member 103 can play a decorative role. In this embodiment, the base structure 101 is a chair back 102, the decorative member 103 is a back shell 104, and the decorative member 103 is provided at the rear side of the base structure 101. The user can change the appearance of the rear side of the chair 100 by replacing the back shell 104 (decorative member 103).

[0029] As Figure 3 shown, the chair 100 further includes a magnetic attraction assembly 105. The magnetic attraction assembly 105 includes a first connecting member 108 and a second connecting member 109. The first connecting member 108 is connected to the base structure 101, the second connecting member 109 is connected to the decorative member 103, and the first connecting member 108 and the second connecting member 109 are magnetically connected. More specifically, both the first connecting member 108 and the second connecting member 109 are provided as magnets; or, one of the first connecting member 108 and the second connecting member 109 is provided as a magnet, and the other is made of iron. The connection between the first connecting member 108 and the base structure 101 can be a detachable connection or a non-detachable connection. Similarly, the connection between the second connecting member 109 and the decorative member 103 can be a detachable connection or a non-detachable connection.

[0030] The basic structure 101 and the decorative member 103 of the chair 100 of the present utility model are connected by a magnetic attraction assembly 105, and the basic structure 101 and the decorative member 103 are fixed to each other by magnetic attraction force. If the user needs to disassemble the decorative member 103, the user only needs to pull the decorative member 103 to release the magnetic attraction connection between the basic structure 101 and the decorative member 103. Conversely, if the user needs to install the decorative member 103, the user only needs to bring the decorative member 103 close to the basic structure 101 until the two are magnetically attracted to each other. During the installation and disassembly of the decorative member 103, the user does not need to screw in screws or use tools such as screwdrivers. Therefore, the replacement convenience of the decorative member 103 of the chair 100 is relatively high.

[0031] In some embodiments not shown, the first connecting member 108 is embedded in the basic structure 101, and the second connecting member 109 is embedded in the decorative member 103. For example, both the basic structure 101 and the decorative member 103 are made of plastic. During the process of manufacturing the basic structure 101 by injection molding, the first connecting member 108 can be placed in the mold and then injection molded. In this way, after the basic structure 101 is formed, the first connecting member 108 is buried in the basic structure 101. The method of burying the second connecting member 109 in the decorative member 103 is similar to the foregoing method and will not be elaborated here. Since the first connecting member 108 is embedded in the basic structure 101 and the second connecting member 109 is embedded in the decorative member 103, during the assembly process of the chair 100, the assembler does not need to assemble the first connecting member 108 and the basic structure 101, nor does it need to assemble the second connecting member 109 with the decorative member 103, which is beneficial to improving the assembly convenience of the chair 100. In addition, the first connecting member 108 is not easily dropped from the basic structure 101, and the second connecting member 109 is not easily dropped from the decorative member 103.

[0032] In other embodiments, the first connecting member 108 is detachably connected to the basic structure 101, and the second connecting member 109 is detachably connected to the decorative member 103. In this way, the processing difficulty of the basic structure 101 and the decorative member 103 is relatively low, and when the first connecting member 108 or the second connecting member 109 is damaged, the user can replace the first connecting member 108 and the second connecting member 109.

[0033] As Figure 5As shown, in a specific embodiment, the chair 100 further includes a first screw 110 and a second screw 111. The first connecting member 108 is connected to the base structure 101 through the first screw 110, and the second connecting member 109 is connected to the decorative member 103 through the second screw 111. Fixing the two connecting members respectively by two screws is beneficial to improving the connection firmness between the first connecting member 108 and the base structure 101, and improving the connection firmness between the second connecting member 109 and the base structure 101. In some embodiments not shown, the first connecting member 108 and the base structure 101 can also be connected by bonding, snap connection and other means, and the second connecting member 109 and the decorative member 103 can also be connected by bonding, snap connection and other means.

[0034] It should be noted that although the first connecting member 108 and the base structure 101 are fixed by the first screw 110, and the second connecting member 109 and the decorative member 103 are fixed by the second screw 111, screws do not need to be screwed during the installation and removal of the decorative member 103. Only when it is necessary to replace the first connecting member 108 itself and the second connecting member 109 itself, screws need to be screwed. Generally speaking, the frequency of replacing the first connecting member 108 or the second connecting member 109 is much lower than the frequency of replacing the decorative member 103.

[0035] As Figure 5 and Figure 6 As shown, the shapes of the first connecting member 108 and the second connecting member 109 are both set to be circular rings, which is beneficial to reducing the processing difficulty of the first connecting member 108 and the second connecting member 109. The first connecting member 108 includes a first through hole 113, and the first screw 110 passes through the first through hole 113. The second connecting member 109 includes a second through hole 119, and the second screw 111 passes through the second through hole 119. The outer surface of the first connecting member 108 includes a first connecting surface 121, and one end of the first through hole 113 is arranged on the first connecting surface 121. The outer surface of the second connecting member 109 includes a second connecting surface 122, and one end of the second through hole 119 is arranged on the second connecting surface 122. The first connecting surface 121 and the second connecting surface 122 are mutually attached, which is beneficial to reducing the distance between the first connecting member 108 and the second connecting member 109, enhancing the magnetic attraction force between the first connecting member 108 and the second connecting member 109, and thus improving the connection firmness between the decorative member 103 and the base structure 101.

[0036] In this embodiment, the first connection surface 121 is a plane, the first connection surface 121 is the rear end surface of the first connecting member 108, and the nut of the first screw 110 (the first nut 115) does not protrude relative to the first connection surface 121. Similarly, the second connection surface 122 is a plane, the second connection surface 122 is the front end surface of the second connecting member 109, and the nut of the second screw 111 (the second nut) does not protrude relative to the second connection surface 122. In this way, the first connection surface 121 and the second connection surface 122 can be made to fit together. In other embodiments, the first connection surface 121 and the second connection surface 122 can also be provided as curved surfaces, as long as the two can fit together.

[0037] As Figure 6 shown, the wall of the first through hole 113 includes a first tapered surface 114, the first screw 110 includes a first nut 115, and the outer peripheral surface of the first nut 115 includes a second tapered surface 116. Please refer to Figure 5 and Figure 6 , the first tapered surface 114 fits with the second tapered surface 116, so that the first nut 115 presses the first connecting member 108 against the base structure 101. Similarly, the wall of the second through hole 119 includes a third tapered surface 120, the second screw 111 includes a second nut 117, and the outer peripheral surface of the second nut 117 includes a fourth tapered surface 118. The third tapered surface 120 fits with the fourth tapered surface 118, so that the second nut 117 presses the second connecting member 109 against the decorative member 103.

[0038] As Figure 5 and Figure 6 shown, the first nut 115 and the second nut 117 are arranged facing each other. Here, a first direction and a second direction are defined: the first screw 110 and the second screw 111 are arranged in sequence along the first direction, and the second direction is opposite to the first direction. As Figure 6 shown, if the first screw 110 and the second screw 111 are arranged in sequence from front to back, then the first direction is the direction from front to back, and the second direction is the direction from back to front. Along the second direction, the first tapered surface 114 gradually converges towards the central axis of the first connecting member 108, and the second tapered surface 116 gradually converges towards the central axis of the first nut 115. In this way, the shapes of the first tapered surface 114 and the second tapered surface 116 can be made to match. Similarly, along the first direction, the third tapered surface 120 gradually converges towards the central axis of the second connecting member 109, and the fourth tapered surface 118 gradually converges towards the central axis of the second nut 117. In this way, the shapes of the third tapered surface 120 and the fourth tapered surface 118 can be made to match.

[0039] In some other embodiments not shown, the hole walls of the first through hole 113, the hole walls of the second through hole 119, the first nut 115, and the second nut 117 may also not be provided with tapered surfaces. For example, the first through hole 113 is provided as a stepped hole, the hole wall of the stepped hole includes a stepped surface, the front end surface of the first nut 115 is a flat surface, and the front end surface of the first nut 115 abuts against the stepped surface, so that the first nut 115 presses the first connecting member 108 against the base structure 101. Similarly, the second through hole 119 may also be provided as a stepped hole, which will not be elaborated here.

[0040] As Figure 5 and Figure 6 shown, the base structure 101 may further be provided with a positioning groove 112, and both the first connecting member 108 and the second connecting member 109 are arranged in the positioning groove 112. The positioning groove 112 can position the first connecting member 108 and the second connecting member 109, thereby preventing the decorative member 103 from shaking relative to the base structure 101. Moreover, during the installation or disassembly process of the decorative member 103, the positioning groove 112 can also guide the movement of the second connecting member 109, facilitating the user to replace the decorative member 103.

[0041] In some embodiments, in order to improve the connection firmness between the decorative member 103 and the base structure 101, a plurality of magnetic attraction components 105 may be provided. For example, in this embodiment, the number of magnetic attraction components 105 is four, and the main body of the decorative member 103 is radially arranged. More specifically, the main body is in an X shape. As Figure 2 shown, the main body includes four spoke portions 107, the spoke portion 107 includes a first end and a second end 106, all the first ends intersect with each other, and each second end 106 is provided with a second connecting member 109. In some other embodiments not shown, the number of spoke portions 107 may also be set to three. Correspondingly, the decorative member 103 is in a T shape or a Y shape. Of course, the number of spoke portions 107 may also be greater than four, as long as the number of spoke portions 107 is not less than three. The shapes that the decorative member 103 can adopt will not be listed one by one here.

[0042] In some embodiments not shown, the chair 100 further includes a light source (not shown), the light source is installed on the surface of the decorative member 103, and the light source is located on the surface of the decorative member 103 facing away from the base structure 101. For example, if the base structure 101 is the backrest 102 and the decorative member 103 is the back shell 104, then the light source may be located on the rear surface of the back shell 104. The light emitted by the light source installed on the decorative member 103 can enhance the aesthetics of the chair 100.

[0043] In some other embodiments, the light source may also be located between the decorative member 103 and the infrastructure 101, and the decorative member 103 is provided with a light-transmitting area capable of transmitting light. The light source is arranged opposite to the light-transmitting area, and the light emitted by the light source can be emitted from the light-transmitting area. For example, the light source may be located on the front side of the carapace 104 and on the rear side of the chair back 102, and the light-transmitting area of the decorative member 103 is made of a transparent material (such as glass, transparent plastic, etc.).

[0044] The chair 100 in which the infrastructure 101 is the chair back 102 and the decorative member 103 is the carapace 104 has been introduced above. In some other embodiments, the infrastructure 101 may also be configured as an armrest, chair legs, a headrest, a lumbar pillow, a seat cushion, and so on; correspondingly, the decorative member 103 may be configured as a shell member similar to armor for decorating the armrest, chair legs, headrest, lumbar pillow, or seat cushion. The material of the decorative member 103 may be metal, plastic, and so on.
