[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The folding chair 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1-Figure 6 As shown, the folding chair 1 according to the embodiment of the utility model includes a folding chair body 10 , a seat belt storage box 20 and a first driving member 30 .

[0034] The folding chair body 10 includes a folding frame 11 and a seat belt 12. The folding frame 11 includes a folding state and an unfolding state. The folding frame 11 can be switched between the folding state and the unfolding state. The seat belt storage box 20 is arranged on the folding frame 11. The seat belt storage box 20 includes a accommodating cavity 21 and a storage port 22. The storage port 22 connects the accommodating cavity 21 and the outside. The seat belt 12 is passed through the storage port 22 and one end is located in the accommodating cavity 21. The first driving member 30 is arranged on the seat belt storage box 20. The first driving member 30 is used to apply a retraction force to the seat belt 12 to move into the accommodating cavity 21.

[0035] When the folding frame 11 is in the unfolded state, at least a portion of the seat belt 12 is located outside the accommodating cavity 21, and the user can sit on the seat belt 12. When the folding frame 11 is switched to the folded state, under the action of the first driving member 30, the first driving member 30 applies a retracting force to the seat belt 12 to move the seat belt 12 from the storage opening 22 to the accommodating cavity 21, so that when the folding frame 11 is in the folded state, the seat belt 12 is stored in the accommodating cavity 21. In this way, when the folding chair 1 is not in use, the seat belt 12 can be stored in the accommodating cavity 21 to prevent the seat belt 12 from being scattered outside in a disorderly manner. On the one hand, it is convenient to improve the aesthetics of the folding chair 1, and on the other hand, it can prevent the seat belt 12 from being hooked with items outside.

[0036] Specifically, when the first driving member 30 applies a retraction force to the seat belt 12, the seat belt 12 can be driven to automatically move into the accommodating cavity 21 to automatically store the seat belt 12 without the user manually storing the seat belt 12, thereby reducing the user's operating steps and improving the user's experience.

[0037] According to the folding chair 1 of the embodiment of the utility model, when the folding frame 11 is in the folded state, the seat belt 12 is stored in the accommodating cavity 21 to prevent the seat belt 12 from being scattered outside in a disorderly manner. The folding frame 11 automatically switches to the folded state. On the one hand, it is convenient to improve the aesthetics of the folding chair 1, and on the other hand, it can prevent the seat belt 12 from being hooked on the objects outside.

[0038] The folding chair 1 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, the folding chair 1 includes a folding chair body 10 , a seat belt storage box 20 and a first driving member 30 .

[0040] In some embodiments of the present invention, Figure 4 As shown, the first driving member 30 includes a moving member 31 and a retracting member 32. The moving member 31 can be movably arranged in the accommodating cavity 21 along a set direction. The seat belt storage box 20 includes a fixing portion 23. The seat belt 12 is wound around the moving member 31 and one end is fixed to the fixing portion 23. The retracting member 32 is connected between the moving member 31 and the inner wall surface of the seat belt storage box 20. The retracting member 32 is used to apply a retracting force to the seat belt 12 to move into the accommodating cavity 21 through the moving member 31, so that under the action of the retracting member 32, the seat belt 12 is automatically stored in the accommodating cavity 21.

[0041] It is understandable that the seat belt 12 is wound between the movable member 31 and the fixed portion 23 and one end is fixed to the fixed portion 23, so that the seat belt 12 can be neatly stored in the accommodating cavity 21 to prevent the seat belt 12 from getting tangled in the accommodating cavity 21.

[0042] When the moving member 31 moves along the set direction, the distance between the moving member 31 and the fixed portion 23 changes, and the length of the seat belt 12 wound between the moving member 31 and the fixed portion 23 changes.

[0043] Specifically, when the retracting member 32 drives the movable member 31 to move along the set direction toward the direction away from the fixed portion 23, the distance between the movable member 31 and the fixed portion 23 becomes larger. At this time, the length of the seat belt 12 wound between the movable member 31 and the fixed portion 23 becomes longer, that is, more and more seat belts 12 are accommodated in the accommodating cavity 21. At this time, the folding frame 11 switches to a folded state.

[0044] When the movable member 31 overcomes the action of the retracting member 32 and moves along the set direction toward the fixed portion 23, the distance between the movable member 31 and the fixed portion 23 becomes smaller. At this time, the length of the seat belt 12 wound between the movable member 31 and the fixed portion 23 becomes shorter, that is, more and more seat belts 12 extend out of the accommodating cavity 21 from the storage opening 22. At this time, the folding frame 11 switches to the unfolded state.

[0045] In some embodiments, Figure 4-Figure 6 As shown, the setting direction extends in the up-down direction, the moving member 31 is arranged below the fixed portion 23, and the retraction force applied by the retracting member 32 to the seat belt 12 is a downward force. Under the action of the retracting member 32, the moving member 31 moves downward, at which time the distance between the moving member 31 and the fixed portion 23 becomes larger, and the length of the seat belt 12 wound between the moving member 31 and the fixed portion 23 becomes longer. When the moving member 31 is driven by a driving force to overcome the force of the retracting member 32 and moves upward, the distance between the moving member 31 and the fixed portion 23 becomes smaller, and the length of the seat belt 12 wound between the moving member 31 and the fixed portion 23 becomes shorter.

[0046] In some optional embodiments of the present invention, Figure 5 As shown, the retracting member 32 includes an elastic retracting member. When the moving member 31 moves along a set direction, the retracting member 32 will adaptively undergo elastic deformation so that the retracting member 32 always keeps in cooperation with the moving member 31, thereby being able to apply a retracting force to the seat belt 12 through the moving member 31.

[0047] In some embodiments, Figure 6As shown, the elastic retractable member is in a stretched state so as to always exert a downward force on the movable member 31. The first driving member 30 includes a plurality of elastic retractable members. The movable member 31 is formed as a movable rod. The length direction of the movable rod extends along the left-right direction. The plurality of elastic retractable members are arranged at intervals along the left-right direction. One end of the elastic retractable member is fixed to the lower bottom wall of the accommodating cavity 21, and the other end is fixed to the movable member 31. The plurality of elastic retractable members exert a downward force on the movable member 31 to increase the force on the movable member 31, thereby enabling the movable member 31 to pull the seat belt 12 to move so as to smoothly accommodate the seat belt 12 in the accommodating cavity 21.

[0048] In some optional embodiments of the present invention, Figure 4-Figure 6 As shown, the folding chair 1 further includes a guide portion 60, which extends along a set direction. The guide portion 60 is used to guide the movement of the moving member 31 so that the moving rod can move smoothly along the set direction, thereby enabling the folding frame 11 to switch between a folded state and an unfolded state.

[0049] like Figure 4 , Figure 6 As shown, in the present embodiment, the guide portion 60 is a guide groove connected to the accommodating chamber 21, and a guide groove is respectively provided on the left and right side walls of the accommodating chamber 21, and the guide groove extends along a set direction. The left and right ends of the movable member 31 extend into the guide groove and slide with the two inner walls opposite to the guide groove to limit and guide the moving direction of the movable member 31, so that the movable member 31 can move smoothly along the set direction.

[0050] In some optional embodiments of the present invention, Figure 6 As shown, the fixing portion 23 includes a fixing rod, one end of the seat belt 12 is connected to the fixing rod, and the portion of the seat belt 12 located between the moving part 31 and the storage port 22 is wrapped around the fixing rod, so that the fixing rod is used to support the portion of the seat belt 12 located between the moving part 31 and the storage port 22, thereby reducing the possibility of contact between the seat belt 12 and the edge of the storage port 22, thereby reducing the friction between the seat belt 12 and the edge of the hole of the storage port 22, and increasing the service life of the seat belt 12.

[0051] Specifically, the portion of the seat belt 12 between the movable member 31 and the storage port 22 is tangent to the fixed rod, and the fixed rod is used to support the portion of the seat belt 12 between the movable member 31 and the storage port 22. The extension direction of the portion of the seat belt 12 between the movable member 31 and the storage port 22 can be adjusted by changing the position of the fixed rod. This makes it easier to make the extension direction of the seat belt 12 from the storage port 22 to the external portion parallel to the axial direction of the storage port 22, or to make the angle formed between the extension direction of the seat belt 12 from the storage port 22 to the external portion and the axial direction of the storage port 22 smaller, so as to reduce the possibility of contact between the seat belt 12 and the edge of the storage port 22, thereby facilitating the reduction of friction between the seat belt 12 and the edge of the hole of the storage port 22.

[0052] In addition, the size of the storage opening 22 can be set larger to reserve enough space for the seat belt 12 to reduce the possibility of the seat belt 12 contacting the edge of the storage opening 22, thereby facilitating the reduction of friction between the seat belt 12 and the edge of the storage opening 22.

[0053] What needs to be explained here is that the angle formed between the extension direction of the seat belt 12 from the storage port 22 to the external part and the axial direction of the storage port 22 is an acute angle formed between the two. The smaller the angle formed between the extension direction of the seat belt 12 from the storage port 22 to the external part and the axial direction of the storage port 22, the closer the extension direction of the seat belt 12 from the storage port 22 to the external part and the axial direction of the storage port 22 are to be parallel.

[0054] In some embodiments, the fixed part 23 is a cylindrical fixed rod, and the movable part 31 is a cylindrical movable rod. This makes it easier to reduce the friction between the seat belt 12 and the fixed part 23 and the movable part 31, thereby increasing the working efficiency of the first driving member 30 and improving the service life of the seat belt 12.

[0055] In some embodiments, the folding chair body 10 includes a plurality of seat belts 12 with a relatively small width, and the plurality of seat belts 12 are arranged at intervals along the length direction of the fixing rod.

[0056] In some examples, such as Figure 1 As shown, the seat belt storage box 20 has a storage opening 22, and the plurality of seat belts 12 are moved from the storage opening 22 to the inside or outside of the accommodating cavity 21. In other examples, such as Figure 6 As shown, the seat belt storage box 20 has a plurality of storage openings 22 , and the plurality of seat belts 12 are correspondingly located at the storage openings 22 and move from the corresponding storage openings 22 to the inside or outside of the accommodating cavity 21 .

[0057] In other embodiments, the folding chair body 10 includes a seat belt 12 with a larger width.

[0058] In some specific embodiments of the present invention, Figure 4 , Figure 6 As shown, the folding chair 1 also includes a limiting portion 50, which is arranged on the fixed rod. The limiting portion 50 includes a first part 51 and a second part 52. The first part 51 and the second part 52 are arranged on both sides of the seat belt 12 in the width direction to limit the seat belt 12 to prevent the seat belt 12 from moving on the fixed rod along the axial direction of the fixed rod.

[0059] like Figure 5 As shown, in the present embodiment, the folding chair body 10 includes a plurality of seat belts 12, a plurality of limiting portions 50 are provided at intervals on the fixed rod, and the seat belts 12 are provided one by one between the first portion 51 and the second portion 52 of the corresponding limiting portion 50 to prevent the seat belts 12 from moving in the axial direction of the fixed rod, to prevent the plurality of seat belts 12 from overlapping, and to prevent the seat belts 12 from interfering with each other.

[0060] In some optional embodiments of the present invention, Figure 7-10 As shown, the folding chair 1 also includes a limit block 61 and a second driving member 62, and the second driving member 62 is used to drive the limit block 61 to move between a first position and a second position. The wall surface of the limit block 61 includes a support surface 611. When the limit block 61 is in the first position, the projections of the limit block 61 and the movable member 31 along the set direction partially overlap. When the folding frame 11 is in the unfolded state, the support surface 611 of the limit block 61 abuts against the movable member 31 to provide a supporting force in the opposite direction of the retraction force to support the position of the movable member 31, so that the movable member 31 can overcome the force of the retraction member 32, thereby limiting the movable member 31 at the specified position. At this time, the retraction member 32 cannot pull the seat belt 12 to move into the accommodating cavity 21 through the movable member 31, so that the folding frame 11 remains in the unfolded state.

[0061] When the limit block 61 is in the second position, the limit block 61 is offset from the projection of the movable member 31 along the set direction. At this time, the support surface 611 is no longer in contact with the movable member 31. At this time, under the action of the retraction force, the retraction member 32 applies a retraction force to the seat belt 12 through the movable member 31 to move it into the accommodating cavity 21, so as to accommodate the seat belt 12 in the accommodating cavity 21. At this time, the folding frame 11 switches to a folded state.

[0062] The position of the limit block 61 can be changed by the second driving member 62 so that the limit block 61 moves between the first position and the second position. Specifically, when the limit block 61 is in the first position, the limit block 61 is on the moving path of the moving member 31, and abuts against the moving member 31 on the supporting surface 611 to provide a supporting force opposite to the direction of the retraction force, so that the moving member 31 can be limited to a specified position. When the limit block 61 is in the second position, the limit block 61 is not on the moving path of the moving member 31.

[0063] For example, when the folding frame 11 needs to be switched to the unfolded state, the movable member 31 is moved toward the direction close to the fixed portion 23 to move the seat belt 12 from the storage port 22 to the outside. When the movable member 31 reaches the specified position, the limit block 61 can be moved to the first position so that the support surface 611 of the limit block 61 abuts against the movable member 31 to limit the position of the movable member 31, thereby preventing the movable member 31 from being affected by the force of the retracting member 32 and moving in the direction away from the fixed portion 23, thereby placing the folding frame 11 in the unfolded state.

[0064] When the folding frame 11 needs to be switched to the folding state, the limit block 61 can be moved to the second position. At this time, the support surface 611 of the limit block 61 is disengaged from the movable member 31. Under the action of the retracting member 32, the movable member 31 moves in a direction away from the fixed portion 23, so that the seat belt 12 moves from the storage opening 22 to the storage cavity, and the folding frame 11 is switched to the folding state.

[0065] In some specific embodiments of the present invention, Figure 8 , Fig. 9 As shown, the wall surface of the limit block 61 includes an inclined surface 612 which is opposite to the supporting surface 611 in a set direction, and the inclined surface 612 gradually moves away from the movable member 31 along the direction of the retraction force. The movable member 31 can squeeze the inclined surface 612 to move the limit block 61 from the first position to the second position. In this way, when the movable member 31 moves in the direction close to the fixed portion 23, the movable member 31 can drive the limit block 61 to move from the first position to the second position. In this way, when the folding frame 11 needs to be switched from the folded state to the unfolded state, when the movable member 31 moves in the direction close to the fixed portion 23, no matter the limit block 61 is in the first position or the second position, the movable member 31 can move smoothly in the direction close to the fixed portion 23, and the folding frame 11 can switch from the folded state to the unfolded state without deliberately adjusting the position of the limit block 61, thereby reducing the user's operation and improving the user's experience.

[0066] In some embodiments, Figure 8 , Fig. 9 As shown, the set direction extends in the up-down direction (it should be understood here that the above direction limitation is only for the convenience of describing the accompanying drawings and will not limit the actual setting position and direction of the folding chair), the retracting member 32 has a downward retracting force on the moving member 31, the limit block 61 is located on the left side of the moving member 31, the limit block 61 can move between the first position and the second position in the left-right direction, the inclined surface 612 extends obliquely in the downward and leftward direction, and the support surface 611 is located above the inclined surface 612 and extends in the left-right direction.

[0067] When it is necessary to switch the folding frame 11 from the folded state to the unfolded state, an upward force is applied to the moving member 31 so that the moving member 31 overcomes the retraction force of the retraction member 32 and moves upward. When the top of the left end of the moving member 31 first contacts the inclined surface 612, the moving member 31 has a leftward force on the limit block 61 to drive the limit block 61 to move to the left in the direction away from the moving member 31, thereby moving the limit block 61 to the second position, so that the moving member 31 can continue to move upward smoothly. When the moving member 31 moves to the specified position and the second driving member 62 is used to move the limit block 61 to the first position, after the upward force applied to the moving member 31 is removed, the bottom of the moving member 31 and the supporting surface 611 of the limit block 61 are stopped, so that the moving member 31 can be maintained at this position, thereby keeping the folding frame 11 in the unfolded state.

[0068] When the folding frame 11 needs to be switched to the folded state, the second driving member 62 is used to move the limit block 61 to the second position. At this time, the support surface 611 is disengaged from the bottom of the movable member 31. Under the retraction force of the retraction member 32, the movable member 31 moves downward to switch the folding frame 11 to the folded state.

[0069] In some embodiments, Figure 7-10 As shown, a through opening 211 is provided on the left side wall of the accommodating chamber 21, and the inclined surface 612 and the supporting surface 611 of the limiting block 61 can extend into the accommodating chamber 21 from the through opening 211. When the limiting block 61 is in the first position, the supporting surface 611 extends out of the accommodating chamber 21 from the through opening 211, so that the supporting surface 611 can abut against the moving member 31 to provide a supporting force in the opposite direction of the retraction force, so as to support the position of the moving member 31, so that the moving member 31 can overcome the force of the retraction member 32, and then the moving member 31 is limited to the specified position, so that the folding frame 11 is kept in the unfolded state. When the limiting block 61 is in the second external position, the inclined surface 612 and the supporting surface 611 move out of the accommodating chamber 21 from the through opening 211, and at this time, the limiting block 61 will not cause the movement of the moving member 31, and at this time, the folding chair 1 can be switched between the folded state and the unfolded state at will.

[0070] In some specific embodiments of the present invention, Figure 8-Figure 10As shown, the second driving member 62 includes an elastic member 621 and a pressing member 622, and the elastic member 621 and the pressing member 622 are respectively arranged on both sides of the limit block 61 along the set direction. The seat belt storage box 20 includes a mating surface 25 for slidingly cooperating with the inclined surface 612, and the elastic member 621 is used to apply a restoring force to the limit block 61 so that the limit block 61 moves from the second position to the first position along the mating surface 25. At the same time, under the action of the elastic member 621, the limit block 61 is maintained in the first position, so that the support surface 611 is abutted against the moving member 31 to provide a supporting force in the opposite direction of the retraction force, so as to support the position of the moving member 31, so that the moving member 31 can overcome the action of the retraction member 32, thereby limiting the moving member 31 at the specified position, so that the folding frame 11 is maintained in the unfolded state.

[0071] That is to say, when the folding frame 11 is switched to the unfolded state, under the action of the elastic member 621, the limit block 61 can automatically move to the first position, without the user having to manually operate the position of the limit block 61, thereby simplifying the user's operation and improving the user's experience.

[0072] Specifically, when the movable member 31 moves toward the direction close to the fixed portion 23, the movable member 31 moves and squeezes the inclined surface 612 to move the limit block 61 from the first position to the second position. After the movable member 31 continues to move and disengages from the inclined surface 612, under the action of the elastic member 621, the limit block 61 moves from the second position to the first position along the mating surface 25, so that the limit block 61 automatically switches to the first position, so that the support surface 611 can be against the movable member 31, and the movable member 31 is thereby limited at the specified position, so that the folding frame 11 remains in the unfolded state, without the need for the user to manually adjust the position of the limit block 61.

[0073] In some embodiments, Figure 1As shown, the folding frame 11 includes a first annular frame 111 and a second annular frame 112 which are hingedly connected in the middle, and the folding chair 1 includes two seat belt storage boxes 20, which are arranged on the first annular frame 111 and the second annular frame 112. When the folding frame 11 is switched to the unfolded state, manual operation is required to make the two ends of the first annular frame 111 and the second annular frame 112 move in a direction away from each other. At this time, the moving member 31 is forced to move in a direction close to the fixed portion 23. When the moving member 31 moves and squeezes the inclined surface 612 to make the limit block 61 move from the first The folding frame 11 moves to the second position. After the moving member 31 continues to move and disengages from the inclined surface 612, the limit block 61 automatically moves from the second position to the first position along the matching surface 25 under the action of the elastic member 621. At this time, the support surface 611 abuts against the moving member 31 to limit the moving member 31 at a specified position, thereby keeping the folding frame 11 in the unfolded state. In other words, if the folding chair 1 needs to be switched to the unfolded state, it is only necessary to apply a force to the first annular frame 111 and the second annular frame 112, and there is no need to manually operate the second driving member.

[0074] The pressing member 622 is used to apply a driving force opposite to the restoring force to the limit block 61, so that the limit block 61 moves from the first position to the second position along the mating surface 25, so that the support surface 611 and the moving member 31 are disengaged from the stop, and then under the action of the retracting member 32, the moving member 31 automatically moves in a direction away from the fixed portion 23, so that the folding frame 11 switches from the unfolded state to the folded state.

[0075] That is to say, when the folding frame 11 needs to be switched to the folded state, it is only necessary to press the pressing member 622 to move the limit block 61 from the first position to the second position. At this time, under the action of the retracting member 32, the folding frame 11 automatically switches from the unfolded state to the folded state.

[0076] In some embodiments, a through opening 211 is provided on the left side wall of the accommodating cavity 21 , and the inclined surface 612 and the supporting surface 611 of the limiting block 61 can extend into the accommodating cavity 21 from the through opening 211 , and the hole wall of the through opening 211 defines a mating surface 25 .

[0077] Among them, the extension direction of the mating surface 25 and the inclined surface 612 is the same, the mating surface 25 extends downward and leftward, and the mating surface 25 and the inclined surface 612 are slidably matched to use the mating surface 25 to guide the extension direction of the inclined surface 612, thereby guiding the movement of the limit block 61 between the first position and the second position.

[0078] In some embodiments, Fig.10As shown, the second driving member 62 also includes a connecting rod 623, which connects the pressing member 622 and the limit block 61. By pressing the pressing member 622 downward, a downward force can be applied to the limit block 61 through the connecting rod 623. At this time, the inclined surface 612 slides downward and leftward relative to the mating surface 25, so that the limit block 61 overcomes the force of the elastic member 621 and moves downward and leftward, so that the limit block 61 moves from the first position to the second position.

[0079] In some embodiments, Figure 7 As shown, the elastic member 621 is disposed below the limit block 61 , and the elastic member 621 exerts an upward force on the limit block 61 , so that the limit block 61 can move upward and rightward, and the limit block 61 moves from the second position to the first position.

[0080] In some examples, such as Figure 7 As shown, the seat belt storage box 20 also includes a support portion 24, which is arranged on the outer side of the left side wall of the accommodating cavity. The lower end of the elastic member 621 stops at the support portion 24, and the upper end of the elastic member 621 is connected to the limit block 61. The elastic member 621 is in a compressed state to exert an upward force on the limit block 61.

[0081] In some embodiments of the present invention, Figure 1 As shown, the folding frame 11 includes a first annular frame 111 and a second annular frame 112 which are hingedly connected in the middle, and the seat belt storage box 20 is detachably arranged on the first annular frame 111 and / or the second annular frame 112, and the seat belt 12 is arranged between a side portion of the first annular frame 111 and a side portion of the second annular frame 112. By operating the first annular frame 111 and the second annular frame 112, a force that overcomes the action of the first driving member 30 can be applied to the seat belt 12, so that the seat belt 12 can be moved out of the accommodating cavity 21 from the storage port 22, thereby switching the folding frame 11 to the unfolded state.

[0082] The seat belt storage box 20 is detachably arranged on the first annular frame 111 and / or the second annular frame 112, so that the seat belt storage box 20 can be easily removed from the first annular frame 111 and / or the second annular frame 112, thereby facilitating the repair or replacement of the seat belt storage box 20 and the internal parts. For example, when the seat belt 12 is dirty, the seat belt storage box 20 can be removed, and a new seat belt 12 can be replaced or the seat belt 12 can be cleaned.

[0083] In some embodiments, Figure 1As shown, the folding chair 1 includes a first seat belt storage box, a second seat belt storage box and a plurality of seat belts 12. The first seat belt storage box is provided with a first moving member, a first retracting member and a first fixing portion, and the second seat belt storage box is provided with a second moving member, a second retracting member and a second fixing portion. When the folding frame 11 is in a folded state, a portion of the same seat belt 12 is wound around the first moving member and one end is fixed to the first fixing portion, and the other portion is wound around the second moving member and the other end is fixed to the second fixing portion.

[0084] When a force is applied to the first annular frame 111 and the second annular frame 112 so that the ends of the first annular frame 111 and the second annular frame 112 move away from each other, the first movable member moves toward the direction approaching the first fixed portion, and the second movable member moves toward the direction approaching the second fixed portion. At this time, the seat belt 12 extending out of the accommodating cavity 21 becomes longer, so that the folding frame 11 switches to a folded state.
