Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0037] Figures 1 to 3The chair 100 of the first embodiment of the present utility model is shown. The chair 100 includes a basic structure 101 and a decorative member 103. At least a part of the decorative member 103 is exposed outside the basic structure 101, so that the decorative member 103 can play a decorative role. In this embodiment, the basic structure 101 is a chair back 102, the decorative member 103 is a carapace 104, and the decorative member 103 is arranged at the rear side of the basic structure 101. The user can change the appearance of the rear side of the chair 100 by replacing the carapace 104 (the decorative member 103).

[0038] As Figure 1 shown, the chair 100 further includes a snap component 105. As Figure 3 shown, the snap component 105 includes a first snap member 108 and a second snap member 109. The first snap member 108 is connected to the basic structure 101, the second snap member 109 is connected to the decorative member 103, and the first snap member 108 and the second snap member 109 are snap-connected to each other, so that the basic structure 101 and the decorative member 103 are fixed to each other. The connection between the first snap member 108 and the basic structure 101 can be a detachable connection or a non-detachable connection. Similarly, the connection between the second snap member 109 and the decorative member 103 can be a detachable connection or a non-detachable connection. The connection between the first snap member 108 and the basic structure 101 can be an integral connection, and the connection between the second snap member 109 and the decorative member 103 can also be an integral connection.

[0039] Since the basic structure 101 and the decorative member 103 are connected to each other through the snap component 105, when the user needs to replace the decorative member 103, the user only needs to release the snap state of the snap component 105. During the replacement process of the decorative member 103, the user does not need to screw or use tools such as a screwdriver. Therefore, the replacement convenience of the decorative member 103 of the chair 100 is relatively high.

[0040] In some embodiments, the first snap member 108 and the basic structure 101 are fixed to each other, and the second snap member 109 and the decorative member 103 are fixed to each other. In some other embodiments, the second snap member 109 is fixed to the decorative member 103, but the first snap member 108 is movably connected to the basic structure 101. The user can push or pull the first snap member 108 to make the first snap member 108 move relative to the basic structure 101, so as to change the position of the first snap member 108, and then release the snap connection between the first snap member 108 and the second snap member 109. Such a setting facilitates the user to release the snap connection between the first snap member 108 and the second snap member 109.

[0041] When the first engaging member 108 moves relative to the base structure 101, the movement made by the first engaging member 108 can be a linear movement. Such a setting can save the moving space reserved for the first engaging member 108. For example, as Figure 4 shown, the base structure 101 is provided with a first sliding groove 111 which is straightly arranged, and the first engaging member 108 is slidably installed in the first sliding groove 111. In some other embodiments not shown, when the first engaging member 108 moves relative to the base structure 101, the movement made by the first engaging member 108 can also be a rotational movement.

[0042] As Figure 5 shown, in some embodiments, the chair 100 further includes an elastic member 118. Both the first elastic member 118 and the base structure 101 are connected to the elastic member 118. The elastic force of the elastic member 118 is used to restore the engagement between the first engaging member 108 and the second engaging member 109, and to keep the first engaging member 108 and the second engaging member 109 engaged. When the movement made by the first engaging member 108 is a linear movement, the first elastic member 118 can be set as a spring; when the movement made by the first engaging member 108 is a rotational movement, the first elastic member 118 can be set as a torsion spring. Since the elastic force of the elastic member 118 can keep the first engaging member 108 and the second engaging member 109 engaged, the connection firmness between the decorative member 103 and the base structure 101 is relatively high, and the decorative member 103 is not easily detached from the base structure 101. Moreover, since the elastic force of the elastic member 118 can restore the first engaging member 108 and the second engaging member 109 from the unengaged state to the engaged state, the installation convenience of the decorative member 103 is relatively high.

[0043] Figure 5 shows the state when the first engaging member 108 and the second engaging member 109 are engaged with each other, Figure 6 shows the state when the first engaging member 108 and the second engaging member 109 are separated from each other. In Figure 5 , the first engaging member 108 is located at the left end of the first sliding groove 111 (taking the Figure 5 direction as a reference, the left and right directions in Figure 5 and Figure 6 are different from those in the other drawings), at this time the first engaging member 108 and the second engaging member 109 are engaged with each other, thus hindering the decorative member 103 from moving backward relative to the base structure 101, that is, hindering the separation of the decorative member 103 from the base structure 101. In Figure 6 , the first engaging member 108 is located at the right end of the first sliding groove 111. At this time, the first engaging member 108 and the second engaging member 109 are separated from each other (taking the Figure 6 direction as a reference), and the engagement between them is released. The decorative member 103 can move backward relative to the base structure 101, and the user can remove the decorative member 103 from the rear side of the base structure 101.

[0044] Based on Figure 5 if the user needs to disassemble the decorative member 103, the user can first pull the first snap member 108 to the right until Figure 6 the position shown, and then take out the decorative member 103.

[0045] If the user needs to install the decorative member 103, the user can also first pull the first snap member 108 to the right until Figure 6 the position shown, then cover the decorative member 103 on the rear side of the base structure 101, and finally release the first snap member 108. Based on Figure 6 after the user releases the first snap member 108, under the elastic force of the elastic member 118, the first snap member 108 moves to the left and moves to the position as shown in Figure 5 In this way, the snap connection between the first snap member 108 and the second snap member 109 is restored.

[0046] It should be noted that the first snap member 108 and / or the second snap member 109 may be provided with an inclined surface. In this way, during the installation of the decorative member 103, the user does not need to pull the first snap member 108, which is beneficial to improving the replacement convenience of the decorative member 103.

[0047] Specifically, as shown in Figure 7 and Figure 8 the first snap member 108 includes a main body portion 116 and a snap portion 115. The snap portion 115 is connected to one end of the main body portion 116, and the outer surface of the snap portion 115 includes a first inclined surface 114. As shown in Figure 5 the snap portion 115 is used to snap with the second snap member 109, and the main body portion 116 is slidably disposed in the first chute 111. The included angle between the outer normal of the first inclined surface 114 and the locking direction is an acute angle, and when the snap portion 115 and the second snap member 109 are snapped with each other, the first inclined surface 114 faces away from the second snap member 109. Among them, the locking direction satisfies that when the elastic member 118 drives the first snap member 108 and the second snap member 109 to restore the snap connection, the elastic member 118 drives the first snap member 108 to move along the locking direction. If taking Figure 5 and Figure 6 as an example, the locking direction is from right to left, and the outer normal of the first inclined surface 114 is from the right front to the left rear, and the included angle between these two directions is an acute angle.

[0048] During the installation of the decorative member 103, the initial position of the first snap member 108 is as shown in Figure 5As shown, the second engaging member 109 moves from back to front. During the forward movement of the second engaging member 109, after the second engaging member 109 abuts against the second inclined surface 113, the force exerted by the second engaging member 109 on the first engaging member 108 will have a component force along the unlocking direction. Among them, the unlocking direction is opposite to the locking direction, and the unlocking direction can be the direction from left to right. This component force will cause the first engaging member 108 to move along the unlocking direction (move to the right). Therefore, during the forward movement of the second engaging member 109, the second engaging member 109 will gradually push open the first engaging member 108, and when the second engaging member 109 passes over the engaging portion 115 (the second engaging member 109 moves to the position as shown in Figure 6 ), the elastic force of the elastic member 118 drives the first engaging member 108 to reset and move to the position as shown in Figure 6 , so that the first engaging member 108 and the second engaging member 109 are engaged. Therefore, in the case where the first inclined surface 114 is provided, the user only needs to move the decorative member 103 and insert or pass the second engaging member 109 through the base structure 101, and the user does not need to manually adjust the position of the first engaging member 108, which is beneficial to improving the installation convenience of the decorative member 103.

[0049] Similarly, as shown in Figure 5 , the second engaging member 109 includes a second inclined surface 113, and the included angle between the outer normal of the second inclined surface 113 and the locking direction is an obtuse angle. When the first engaging member 108 and the second engaging member 109 are engaged with each other, the second inclined surface 113 faces away from the first engaging member 108. The outer normal of the second inclined surface 113 is the direction from the left rear to the right front. In the case where the second inclined surface 113 is provided, during the forward movement of the second engaging member 109, the second engaging member 109 will gradually push open the first engaging member 108, and then the elastic force of the elastic member 118 drives the first engaging member 108 and the second engaging member 109 to resume engagement. Therefore, in the case where the second inclined surface 113 is provided, the user also only needs to move the decorative member 103 and insert or pass the second engaging member 109 through the base structure 101, and the user does not need to manually adjust the position of the first engaging member 108, which is beneficial to improving the installation convenience of the decorative member 103.

[0050] Figure 5 and Figure 6 In the embodiments shown, both the first inclined surface 114 and the second inclined surface 113 exist at the same time, but in some other embodiments, the chair 100 may also be provided with only the first inclined surface 114 or the second inclined surface 113. As long as one of the first inclined surface 114 or the second inclined surface 113 is provided, the installation convenience of the decorative member 103 can be improved.

[0051] As shown in Figure 5As shown, the chair 100 further includes a first screw 112 and a second screw 110. The first screw 112 is connected to the base structure 101, and the nut of the first screw 112 is used to press against the first engaging member 108, thereby preventing the first engaging member 108 from falling out of the first sliding groove 111. The second engaging member 109 is annular, the second screw 110 is connected to the decorative member 103, and the second engaging member 109 is fixed to the decorative member 103 by the second screw 110.

[0052] As Figure 5 shown, the main body portion 116 is provided with a straight second sliding groove 120, and the extending direction of the second sliding groove 120 is the same as that of the first sliding groove 111. More specifically, the second sliding groove 120 can be set as a kidney-shaped groove. The base structure 101 further includes a guiding portion 123, and the guiding portion 123 is slidably disposed in the second sliding groove 120. The cooperation between the guiding portion 123 and the second sliding groove 120 is conducive to realizing the positioning between the first engaging member 108 and the base structure 101, and guiding the movement of the first engaging member 108. The guiding portion 123 can be cylindrical, and the guiding portion 123 is connected to the first screw 112.

[0053] As Figure 5 and Figure 6 shown, the first engaging member 108 further includes a handle portion 119, the first sliding groove 111 includes an opening 121, and the opening 121 is located at the front end of the first sliding groove 111. At least a part of the handle portion 119 extends out of the first sliding groove 111 from the opening 121. In the sliding direction of the first engaging member 108 (i.e., the left-right direction), the engaging portion 115 and the handle portion 119 are respectively connected to both ends of the main body portion 116. The handle portion 119 is suitable for being grasped by the user, so as to facilitate the user to push or pull the first engaging member 108.

[0054] As Figure 5 shown, the engaging portion 115 protrudes relative to the surface of the main body portion 116 on the side facing away from the opening 121 (i.e., the rear surface of the engaging portion 115). The main body portion 116, the engaging portion 115, and the wall surface of the first sliding groove 111 together define an installation area 117, and an elastic member 118 is disposed in the installation area 117. The elastic member 118 is in a compressed state, that is, no matter the first engaging member 108 is in the Figure 5 position shown or Figure 6 the position shown, the elastic member 118 is in a compressed state. One end of the elastic member 118 abuts against the engaging portion 115, and the other end of the elastic member 118 abuts against the base structure 101. More specifically, the elastic member 118 can abut against the guiding portion 123 of the base structure 101. In this way, the elastic force of the elastic member 118 can drive the first engaging member 108 to move, so that the first engaging member 108 and the second engaging member 109 are restored to the engaged state and maintained in the engaged state. In addition, as Figure 8As shown, the clamping portion 115 is further provided with a positioning groove 122 , and the positioning groove 122 can accommodate one end of the elastic member 118 , so as to position the elastic member 118 .

[0055] like Figure 5 and Figure 6 As shown, in order to facilitate the user to install the decorative member 103, the basic structure 101 is further provided with a positioning hole 124. The positioning hole 124 allows the second clamping member 109 to pass through, and the positioning hole 124 can position the second clamping member 109. The sliding direction of the first clamping member 108 is perpendicular to the axial direction of the positioning hole 124, and the hole wall of the positioning hole 124 is provided with a notch or hole that allows the clamping portion 115 to pass through. When the clamping portion 115 and the second clamping member 109 are mutually clamped, the clamping portion 115 penetrates into the positioning hole 124 from the hole wall of the positioning hole 124.

[0056] In some embodiments, in order to improve the connection firmness between the decorative element 103 and the base structure 101, a plurality of buckle assemblies 105 may be provided. For example, in this embodiment, the number of buckle assemblies 105 is four, and the main body of the decorative element 103 is radial, more specifically, in an X shape. Figure 2 As shown, the main body includes four spokes 107, and the spokes 107 include a first end and a second end 106, all of the first ends intersect each other, and each second end 106 is provided with a second clamping member 109. In other embodiments not shown, the number of spokes 107 can also be set to three, and accordingly, the decorative member 103 is T-shaped or Y-shaped. Of course, the number of spokes 107 can also be greater than four, as long as the number of spokes 107 is not less than three, and the shapes that the decorative member 103 can adopt are not listed one by one here.

[0057] Figure 9 FIG. 2 shows the process of connecting the first clamping member 108 and the second clamping member 109 to each other in the second embodiment. Figure 9 As shown, the first clamping member 108 includes a clamping portion 115 and a connecting portion 126 that are interconnected, and the second clamping member 109 includes a clamping hole 125. The second clamping member 109 is fixedly connected to the decorative member 103, and the two can be connected by bonding, screw connection, etc., or they can be connected in an integrated manner (for example, the two are integrally formed). The clamping hole 125 is a waist-shaped hole, and the clamping portion 115 is also waist-shaped, but the length of the clamping portion 115 is less than the length of the clamping hole 125, and the width of the clamping portion 115 is less than the width of the clamping hole 125, thereby ensuring that the clamping portion 115 can pass through the clamping hole 125 in the unlocked state. Among them, the "length" of a certain structure refers to the length of the structure in Figure 9 The "width" of a structure refers to the size of the structure in the up-down direction. Figure 9The dimension in the left - right direction. The connecting portion 126 and the clamping portion 115 are fixed to each other. The connecting portion 126 can be cylindrical, and the diameter of the connecting portion 126 is smaller than the width of the clamping hole 125 so that the connecting portion 126 can rotate in the clamping hole 125. The connecting portion 126 is rotatably connected to the base structure 101. For example, the connecting portion 126 can be inserted through a mounting hole (not shown) in the base structure 101. One end of the connecting portion 126 is fixedly connected to the clamping portion 115, and the other end of the connecting portion 126 can be connected to a handle or a knob (not shown) so that the user can rotate the first clamping member 108. When the clamping portion 115 rotates, the central axis of the connecting portion 126 is the rotation axis of the clamping portion 115. In some other embodiments, the clamping hole 125 can also be set as a rectangular hole, and the clamping portion 115 can also be set as rectangular.

[0058] As Figure 9 shown, the process of the first clamping member 108 and the second clamping member 109 being clamped to each other is generally as follows.

[0059] First, as Figure 9 shown in (a), at this time, the clamping portion 115 is in the unlocked state, the clamping portion 115 is parallel to the clamping hole 125, and the clamping portion 115 can pass through the clamping hole 125. Among them, "the clamping portion 115 is parallel to the clamping hole 125" means that the length direction of the clamping portion 115 and the length direction of the clamping hole 125 are the same. For example, in Figure 9 (a), the length directions of both the clamping portion 115 and the clamping hole 125 are the up - down direction.

[0060] When the user gradually brings the decorative member 103 closer to the base structure 101, please refer to Figure 9 (a) and Figure 9 (b) in sequence. The first clamping member 108 and the second clamping member 109 approach each other until the clamping portion 115 passes through the clamping hole 125. After the first clamping member 108 passes through the clamping hole 125, the connecting portion 126 is located in the clamping hole 125.

[0061] Subsequently, please refer to Figure 9 (b) and Figure 9 (c) in sequence. The user can rotate the first clamping member 108 to make the clamping portion 115 rotate relative to the base structure 101 until the clamping portion 115 is in the clamped state. More specifically, the rotation angle of the clamping portion 115 can be 90°. In Figure 9 (c), the clamping portion 115 is in the clamped state. If observed along the rotation axis of the clamping portion 115, then the clamping portion 115 is perpendicular to the clamping hole 125, and a part of the clamping portion 115 is located outside the edge of the clamping hole 125, thus preventing the clamping portion 115 from passing through the clamping hole 125. When the first clamping member 108 and the second clamping member 109 are inFigure 9 In the state shown in (c), the two are snap-connected to each other, and the decorative member 103 and the base structure 101 are fixed to each other.

[0062] It should be noted that, as described above, the central axis of the connecting portion 126 is the rotation axis of the snap-connecting portion 115. The rotation axis of the snap-connecting portion 115 extends in the front-rear direction. "Observed along the rotation axis of the snap-connecting portion 115" can be observed from the front to the back or from the back to the front. "The snap-connecting portion 115 is perpendicular to the snap-connecting hole 125" means that the length direction of the snap-connecting portion 115 is perpendicular to the length direction of the snap-connecting hole 125. For example, Figure 9 in (c), the length direction of the snap-connecting portion 115 is the left-right direction, and the length direction of the snap-connecting hole 125 is the up-down direction. As Figure 9 shown in (c), both the left and right ends of the snap-connecting portion 115 are located outside the edge of the snap-connecting hole 125. Therefore, the snap-connecting portion 115 cannot pass through the snap-connecting hole 125. In some other embodiments, the shapes of the first snap-connecting member 108 and the second snap-connecting member 109 can also be swapped with each other, that is, the first snap-connecting member 108 is provided with the snap-connecting hole 125, and the second snap-connecting member 109 is provided with the snap-connecting portion 115.

[0063] If it is necessary to remove the decorative member 103 from the base structure 101, the state change process of the first snap-connecting member 108 and the second snap-connecting member 109 is successively as Figure 9 shown in (c), Figure 9 shown in (b), and Figure 9 shown in (a), which will not be specifically described here.

[0064] Figure 10 and Figure 11 show the first snap-connecting member 108 and the second snap-connecting member 109 of the third embodiment of the present invention. The first snap-connecting member 108 is sleeved outside the second snap-connecting member 109. The second snap-connecting member 109 includes a protrusion 127. The inner surface of the first snap-connecting member 108 is provided with a card slot 128, and the protrusion 127 is stuck in the card slot 128. During the process of connecting the first snap-connecting member 108 and the second snap-connecting member 109 to each other, as the decorative member 103 gradually approaches the base structure 101, the second snap-connecting member 109 will gradually insert into the first snap-connecting member 108 until the protrusion 127 is stuck in the card slot 128.

[0065] As Figure 10 shown, in the third embodiment, the first snap-connecting member 108 is cylindrical, the second snap-connecting member 109 is generally cylindrical, and both the protrusion 127 and the card slot 128 are annular. In some other embodiments not shown, the protrusion 127 and the card slot 128 can also be set as arc-shaped slots or straight slots. The first snap-connecting member 108 and the second snap-connecting member 109 can also be set as quadrangular prism-shaped, hexagonal prism-shaped, and so on.

[0066] In addition, in some other embodiments not shown, the shapes of the first engaging member 108 and the second engaging member 109 may be swapped. That is, the second engaging member 109 may be sleeved outside the first engaging member 108. The first engaging member 108 includes a protrusion 127, and a card slot 128 is provided on the inner peripheral surface of the second engaging member 109.

[0067] 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 is located on the side surface of the decorative member 103 facing away from the base structure 101. For example, if the base structure 101 is the chair back 102 and the decorative member 103 is the carapace 104, the light source may be located on the rear side surface of the carapace 104. The light emitted by the light source installed on the decorative member 103 can enhance the aesthetics of the chair 100.

[0068] In some other embodiments, the light source may also be located between the decorative member 103 and the base structure 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.).

[0069] The above introduced the chair 100 where the base structure 101 is the chair back 102 and the decorative member 103 is the carapace 104. In some other embodiments, the base structure 101 may also be provided as an armrest, chair legs, headrest, lumbar pillow, seat cushion, etc.; correspondingly, the decorative member 103 may be provided as a shell member similar to armor for decorating the armrest, chair legs, headrest, lumbar pillow or seat cushion.
