[0035] This embodiment provides a chair back, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in , the chair back includes a first component, a second component and a locking mechanism 3, wherein the locking mechanism 3 includes a first connecting member 30 fixedly arranged on the first component and a second connecting member 31 movably arranged on the second component. Specifically in this embodiment, the first component is a decorative cover 1, and the second component is a chair back body 2. In other optional embodiments, the first component may also be a chair back body 2, and correspondingly, the second component is a decorative cover 1. Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown in the figure, the second connecting member 31 in this embodiment has a locking position and an unlocking position relative to the chair back body 2, the first connecting member 30 is provided with a slot 300, and the second connecting member 31 is provided with a snap-in portion 310. The snap-in portion 310 is snapped into the slot 300 when the second connecting member 31 is in the locking position, and the snap-in portion 310 is released from the slot 300 when the second connecting member 31 is in the unlocking position.
[0036] By setting up a locking mechanism 3, the assembly of the chair back body 2 and the decorative cover 1 can be achieved. Compared with the assembly using multiple screws or multiple snap-fit structures 5, the assembly operation of the locking mechanism 3 in the present application is more convenient, and the locking mechanism 3 is not easily damaged during the disassembly process, which can increase the service life of the chair back.
[0037] As mentioned above, in other optional embodiments, the first component may also be the seat back body 2, and correspondingly, the second component may be the decorative cover 1. Therefore, the structure of the first connecting member 30 and the arrangement thereof on the decorative cover 1 described in this embodiment may be similarly applied to the seat back body 2 in other optional embodiments; the structure of the second connecting member 31 and the arrangement thereof on the seat back body 2 described in this embodiment may also be similarly applied to the decorative cover 1 in other optional embodiments.
[0038] It is easy to understand that the chair back provided in this embodiment can lock or unlock the second connecting member 31 relative to the first connecting member 30 by controlling the position of the second connecting member 31 relative to the chair back body 2, thereby realizing the assembly of the decorative cover 1 and the chair back body 2. In this embodiment, the switching action of the second connecting member 31 from the unlocked position to the locked position is driven by the elastic member 4, and the switching action of the second connecting member 31 from the locked position to the unlocked position is driven and controlled by the assembly action of the first connecting member 30. The specific description is as follows:
[0039] like Figure 2 and Figure 3 As shown, the locking mechanism 3 in this embodiment further includes an elastic member 4 disposed between the second connecting member 31 and the chair back body 2, and the elastic member 4 applies pressure to the second connecting member 31 so that the second connecting member 31 has a tendency to move toward the locking position. That is, in the absence of external force, the elastic member 4 will drive the second connecting member 31 to move toward the locking position until it remains at the locking position. Further, as Figure 3 and Figure 5As shown, the seat back body 2 in this embodiment is provided with a slot 20 adapted to the first connecting member 30 (specifically in this embodiment, the slot 20 is a through slot, and in other optional embodiments, the slot 20 may also be a non-through groove), the first connecting member 30 is inserted into the slot 20, and an adapted guide structure is provided between the first connecting member 30 and the second connecting member 31, and the first connecting member 30 pushes the second connecting member 31 to switch from the locked position to the unlocked position through the guide structure during the process of the first connecting member 30 being inserted into the slot 20. Of course, when it is necessary to remove the decorative panel, the user may also manually push the second connecting member 31 to switch from the locked position to the unlocked position, so as to release the lock between the first connecting member 30 and the second connecting member 31, thereby removing the decorative cover 1.
[0040] During assembly, the entire decorative cover 1 is buckled onto the chair back body 2, and the first connecting member 30 on the decorative cover 1 is inserted into the slot 20 on the chair back body 2. During the process of inserting the first connecting member 30 into the slot 20, the second connecting member 31 is pushed from the locked position to the unlocked position through the guide structure. After the first connecting member 30 is inserted into the slot 20, the second connecting member 31 is switched from the unlocked position to the locked position under the action of the elastic member 4, so that the snap-in portion 310 on the second connecting member 31 is snapped into the snap-in slot 300 on the first connecting member 30, thereby completing the locking of the two.
[0041] Specifically, Figure 5 As shown in the figure, the first connector 30 includes a long strip-shaped plug-in section 301 and an end 302 bent relative to the plug-in section 301. The end 302 cooperates with the plug-in section 301 to form a slot 300. The aforementioned guide structure includes a first guide surface 3020 formed on the end 302 and a second guide surface 3100 formed on the second connector 31. Specifically in this embodiment, the end 302 is a solid structure that is roughly truncated cone-shaped. An inclined surface is formed between the end surface away from the plug-in section 301 and the part close to the plug-in section 301. The inclined surface is the first guide surface 3020. The plug-in section 301 is roughly half a hollow cylindrical shell.
[0042] During assembly, the entire decorative cover 1 is buckled onto the seat back body 2, and the first connector 30 on the decorative cover 1 is inserted into the slot 20 on the seat back body 2. During the insertion of the first connector 30 into the slot 20, the first guide surface 3020 on the end 302 contacts the second guide surface 3100 on the second connector 31 and pushes the second connector 31 to swing by overcoming the elastic force of the elastic member 4 by the oblique component of the force, so that the second connector 31 moves to the unlocking position. After the end 302 is separated from the second connector 31, the pressure exerted by the end 302 on the second connector 31 is lost, and the second connector 31 moves to the locking position under the action of the elastic member 4 until the clamping portion 310 on the second connector 31 is clamped into the clamping slot 300.
[0043] It is easy to understand that when the clamping portion 310 on the second connection member 31 is clamped into the clamping slot 300 on the first connection member 30, the first connection member 30 is also inserted into the slot 20 adapted thereto. In this way, the decorative cover 1 can be limited in position not only along the axial direction of the first connection member 30 by the cooperation between the clamping portion 310 and the clamping slot 300, but also along the radial direction of the first connection member 30 by the cooperation between the first connection member 30 and the slot 20.
[0044] It should be noted that the elastic member 4 in this embodiment is a compression spring, the second connecting member 31 is swingably arranged on the backrest body 2, a limiting column is arranged on the backrest body 2 and one end of the second connecting member 31, one end of the compression spring is set outside the positioning column on the backrest body 2, and the other end of the compression spring is set outside the positioning column on the second connecting member 31. In other optional embodiments, the elastic member 4 can also be a metal spring, or the elastic member 4 can also be a spring structure such as a tension spring or a torsion spring, and the swing connection structure between the second connecting member 31 and the backrest body 2 can be changed accordingly, which is easy to understand for those skilled in the art. Further, the second connecting member 31 can also be slidably arranged on the backrest body 2, that is, in this embodiment, the second connecting member 31 switches between the unlocking position and the locking position by a swinging action, and in other optional embodiments, the second connecting member 31 can also be designed to switch between the unlocking position and the locking position by a sliding action along a straight line.
[0045] Combination Figure 2 and Figure 3 As shown, the second connecting member 31 in this embodiment is swingably arranged on the chair back body 2 through the rotating shaft 21. Specifically, the chair back body 2 is provided with the rotating shaft 21, and the second connecting member 31 is provided with a rotating hole adapted to the rotating shaft 21, and the second connecting member 31 is rotatably sleeved outside the rotating shaft 21 through the rotating hole. At the same time, an axial hole is opened on the rotating shaft 21 along its axial direction. After the second connecting member 31 is sleeved outside the rotating shaft 21, the second connecting member 31 can be limited along the axial direction of the rotating shaft 21 by screwing the screw 22 from the outside into the axial hole, so as to prevent the second connecting member 31 from coming off the rotating shaft 21.
[0046] Furthermore, the second connecting member 31 is formed with an abutting portion 311 and a clamping portion 310, the elastic member 4 applies pressure to the abutting portion 311, and the abutting portion 311 and the clamping portion 310 are respectively located on both sides of the rotating shaft 21. Furthermore, the second connecting member 31 is also formed with an operating portion 312, the abutting portion 311 is located at one end of the second connecting member 31, and the operating portion 312 is located at the other end of the second connecting member 31. In this way, when the decorative cover 1 needs to be replaced, the operator can press the operating portion 312 by hand to overcome the elastic force of the elastic member 4 to drive the second connecting member 31 to swing, release the lock between the second connecting member 31 and the first connecting member 30, and then gently push the decorative cover 1 to remove it.
[0047] Combination Figure 4 , Fig.10 and Fig.11 As shown in , the chair back provided in this embodiment further includes a buckle structure 5 disposed between the decorative cover 1 and the chair back body 2. The buckle structure 5 includes a first buckle arm 50 disposed on the decorative cover 1, a first buckle groove 51 formed between the first buckle arm 50 and the decorative cover 1, a second buckle arm 52 disposed on the chair back body 2, and a second buckle groove 53 formed between the second buckle arm 52 and the chair back body 2. The first buckle arm 50 is snapped into the second buckle groove 53, and the second buckle arm 52 is snapped into the first buckle groove 51. After the buckle structure 5 is provided, when the decorative cover 1 needs to be assembled, the operator first takes the decorative cover 1, then snaps the first buckle arm 50 into the second buckle groove 53 and snaps the second buckle arm 52 into the first buckle groove 51, and then pushes the decorative cover 1 to buckle toward the chair back body 2, so that the snap-in portion 310 on the second connecting member 31 can be snapped into the snap groove 300 on the first connecting member 30, and the installation and fixation of the decorative cover 1 and the chair back body 2 are completed. When the decorative cover 1 needs to be disassembled and replaced, the operator first presses the operating portion 312 of the second connecting member 31 by hand to disengage the clamping portion 310 on the second connecting member 31 from the clamping slot 300 on the first connecting member 30 to complete the unlocking, and then lifts the decorative cover 1 to disengage the first clamping arm 50 from the second clamping slot 53 and the second clamping arm 52 from the first clamping slot 51. The disassembly operation is completed.
[0048] It is easy to understand that, by designing the positions of the locking mechanism 3 and the snap structure 5 , when the snap structure 5 between the decorative cover 1 and the seat back body 2 is aligned and inserted, the first connecting member 30 can be roughly aligned with the slot 20 to facilitate the insertion operation.
[0049] Different from the complex buckle structure used on such chair backs in the related art, the buckle structure 5 in this embodiment only needs to limit the decorative cover 1 and the chair back body 2 along the front-to-back direction (the chair back is applied to the seat, with the direction facing the user sitting on the seat as the front and the direction leaning back as the back). In the related art, the buckle structure used on such chair backs needs to be set in multiple groups, and the multiple groups of buckle structures need to be arranged in the height direction and the left-right direction of the chair back, which makes it easy to cause one or more groups of buckle structures to be damaged due to excessive deformation during disassembly. However, the buckle structure 5 in this embodiment only needs to be set in one group, or multiple groups are set along the same height. When disassembling, as long as the lock between the first connecting member 30 and the second connecting member 31 is released first, the first buckle arm 50 can be easily removed from the second buckle groove 53 and the second buckle arm 52 can be removed from the first buckle groove 51.
[0050] By setting the above-mentioned relatively simple buckle structure 5, the number of sets of the locking mechanism 3 can be reduced, which can further reduce the difficulty of assembly and reduce the cost. Specifically, in this embodiment, two sets of locking mechanisms 3 and one set of buckle structures 5 are set between the decorative cover 1 and the seat back body 2. The two sets of locking mechanisms 3 are located at the upper end of the seat back along the height direction of the seat back, and the two sets of locking mechanisms 3 are located at the two ends of the seat back along the width direction of the seat back. The buckle structure 5 and the two sets of locking mechanisms 3 are distributed in a triangular shape, and the buckle structure 5 is located below the two sets of locking mechanisms 3. The above design can take into account both the firmness of connection and the ease of assembly and disassembly, as described below:
[0051] In some optional embodiments, only the locking mechanism 3 may be provided without the above-mentioned buckle structure. For example, three sets of locking mechanisms 3 may be provided in the above-mentioned triangular distribution, or four sets of locking mechanisms 3 may be provided in the above-mentioned trapezoidal distribution, so that the decorative cover 1 and the seat back body 2 can be installed and fixed. However, during disassembly, although it is still only necessary to simply press the operating portion 312 on the second connecting member 31 to unlock the first connecting member 30 and the second connecting member 31, since multiple sets of locking mechanisms 3 are provided, two operators are required to cooperate in the unlocking operation. By combining the above-mentioned locking mechanism 3 with the buckle structure 5 provided in this embodiment, the difficulty of disassembly operation can be further reduced. Only one operator is required to press the operating portion 312 on the second connecting member 31 of the two sets of locking mechanisms 3 with both hands at the same time. After unlocking, the decorative cover 1 can be easily removed by lifting and pushing and pulling the decorative cover 1.
[0052] Of course, in other optional embodiments, two groups of snap structures 5 can also be provided according to the shape and size requirements of the decorative cover 1. The two groups of snap structures 5 are at the same height, and the two groups of locking mechanisms 3 and the two groups of snap structures 5 are arranged in a trapezoidal distribution, which does not increase the difficulty of disassembly and assembly.
[0053] The chair back provided in the present embodiment can be applied to a seat. Specifically, the seat includes the chair back provided in the present embodiment, and other structures of the seat are the same as those in the prior art. Since the chair back provided in the present embodiment is applied to the seat, the decorative cover 1 can be easily disassembled and replaced. Especially when the seat is an e-sports chair, the decorative cover 1 with different appearance patterns or colored lights can be replaced as needed to better meet user needs and simplify user operations.
[0054] Finally, it should be noted that the above-mentioned implementation modes are only optional embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
