[0036] Embodiment 1

[0037] This embodiment provides a bottom support assembly 10 for a moon chair, such as Figures 1 to 5 As shown, it includes an upper support assembly 100 supporting a seat cushion (not shown in the figure), and a lower support assembly 101 in contact with the ground; the bottom support assembly 10 also includes:

[0038] The upper connecting seat 102 is opposite to the bottom center of the upper supporting assembly 100. The upper supporting assembly 100 includes a plurality of upper supporting rods 1000 extending obliquely downward, and the ends of each upper supporting rod 1000 are engaged with the upper connecting seat 102;

[0039] A lower connecting seat 103 is rotatably connected to the upper connecting seat 102 and is opposite to the top center of the lower supporting assembly 101. The lower supporting assembly 101 includes a plurality of lower supporting rods 1010 extending obliquely upward, and the ends of each lower supporting rod 1010 are engaged with the lower connecting seat 103; and

[0040] The swing assembly is installed on the upper connecting seat 102 and / or the lower connecting seat 103 and is used to provide a swing force for the upper connecting seat 102 when driven by a user.

[0041] Compared with the prior art, the beneficial effects of the utility model are: the overall structure is more compact and the degree of component reuse is higher. Specifically, when the bottom support assembly 10 is unfolded and placed, the lower support assembly 101 is in contact with the ground to support the entire moon chair; when the user sits on the seat cushion of the moon chair, the upper support assembly 100 can support the user; when shaking, the upper connecting seat 102 and the part connected to the upper support assembly 100 and the upper support assembly 100 can swing at the same time. The upper connecting seat 102 is connected to each upper support rod 1000 at the same time, and the lower connecting seat 103 is connected to each lower support rod 1010 at the same time, that is, the upper connecting seat 102 and the lower connecting seat 103 can both be connected to the rods on both sides at the same time, and the degree of reuse is high. At the same time, the upper support assembly 100 and the lower support assembly 101 are both in a folded shape, which is conducive to saving space. Combined with the reuse of the upper connecting seat 102 and the lower connecting seat 103, the overall structure is more compact.

[0042] In some embodiments, Figure 3 to Figure 4 As shown, the swing assembly includes a torsion spring 1040, the axis of which is perpendicular to the height direction of the upper support assembly 100, and the two ends of the torsion spring 1040 are respectively fixed to the upper connecting seat 102 and the lower connecting seat 103. The torsion spring 1040 is also called a torsion spring or a torsion elastic element. The principle is to utilize the elastic deformation characteristics of the material to undergo torsion deformation under the action of an external force, and to restore the original state when the external force is removed. Therefore, under the action of the torsion spring 1040, when the moon chair is pushed or leaned on, the upper connecting seat 102 can swing relative to the lower connecting seat 103, thereby causing the moon chair to swing.

[0043] Among them, (1) the number of torsion springs 1040 can be flexibly set according to actual needs, including but not limited to 1-3. When multiple torsion springs 1040 are set, the torsion springs 1040 are evenly distributed (such as Figure 2 (2) The diameters of the two ends of the torsion spring 1040 may be different, that is, the diameter of one end of the torsion spring 1040 is large and the diameter of the other end is small. When the torsion spring 1040 is squeezed by an external force, the different diameters of the two ends of the torsion spring 1040 can provide space for the contraction of the torsion spring 1040, which is beneficial to the contraction deformation of the torsion spring 1040.

[0044] In some embodiments, a sound insulation sleeve (not shown) is further provided on the outside of the torsion spring 1040. Exemplarily, the sound insulation sleeve is located between the torsion spring 1040 and the upper connecting seat 102, and the sound insulation sleeve covers the torsion spring 1040. The sound insulation sleeve is made of sound insulation material, such as sound-absorbing foam.

[0045] In some embodiments, Figure 2As shown, the upper connecting seat 102 and / or the lower connecting seat 103 is provided with an installation cavity 1020 or a first hanging ear for fixing the end of the torsion spring 1040, so as to facilitate and quickly complete the installation of the torsion spring 1040.

[0046] In some embodiments, Figure 3 to Figure 4 As shown, the bottom support assembly 1 also includes an auxiliary positioning assembly, which includes a buffer pad 1050 and a torsion spring retaining ring 1051. The buffer pad 1050 can be elastic rubber or elastic plastic, which can not only reduce the vibration of the moon chair's swing, thereby improving the swing comfort, but also be used to limit the extreme position of the moon chair's swing; the torsion spring retaining ring 1051 can be used to limit the axial position of the torsion spring 1040, so that the torsion spring 1040 does not move when it is twisted and deformed.

[0047] In some embodiments, Figure 3 to Figure 4 As shown, the bottom support assembly 1 also includes a rotating connection assembly that rotatably connects the upper connection seat 102 and the lower connection seat 103, and the rotating connection assembly includes a screw rod 1060 and a screw 1061 that matches the screw rod 1060; at least one end of the screw rod 1060 is provided with a screw 1061; the axis of the screw rod 1060 is perpendicular to the height direction of the upper support assembly 100; the upper connection seat 102 is sleeved on the screw rod 1060 and rotates around it. When the torsion spring 1040 is used to provide the swing force, the screw rod 1060 not only acts as a rotating shaft, but also can cooperate with the screw 1061 to install and fix the torsion spring 1040.

[0048] In some embodiments, Figures 1 to 5As shown, the upper connecting seat 102 is formed with an upper connector 1021 on the outer edge, and the upper connector 1021 is plugged into the upper support rod 1000 and corresponds to it one by one; the lower connecting seat 103 is formed with a lower connector 1030 on the outer edge, and the lower connector 1030 is plugged into the lower support rod 1010 and corresponds to it one by one. The connection between the upper support rod 1000 and the upper connecting seat 102 can adopt a non-detachable connection method or a detachable connection method. Preferably, a detachable connection method is adopted. When the user needs to store, the upper support rod 1000 is separated from the upper connector 102, and the lower support rod 1010 is separated from the lower connector 103, thereby reducing the space required for the storage of the entire moon chair. The above structure is a sleeve connection, and the outer diameter of the end of the upper support rod 1000 is slightly smaller than the inner diameter of the end of the upper connector 1021, and the upper support rod 1000 is fixed by inserting the upper connector 1021. Of course, the upper connector 1021 can also be inserted into the upper support rod 1000 for fixing. The sleeve connection is used to facilitate the rapid completion of the alignment installation work. The connection method between the lower support rod 1010 and the lower connector 1030 and the connection method between the upper support rod 1000 and the upper connection seat 102 are the same, and will not be repeated here. In addition, the detachable connection method includes but is not limited to threaded connection, pin connection, locking nut connection, clamp connection and elastic connection, which are all existing technologies and will not be repeated here.

[0049] In some embodiments, Figure 5 As shown, each upper support rod 1000 and each lower support rod 1010 is provided with a connecting rope 107 inside; the connecting rope 107 is either fixed at both ends to the tail end of the upper support rod 1000 and the upper connecting seat 102, or fixed at both ends to the tail end of the lower support rod 1010 and the lower connecting seat 103. When folding is required, the upper support rod 1000 is pulled out from the upper connecting head 1021, and the upper support rod 1000 is pulled by the connecting rope 107 and can only be folded and stored around the upper connecting head 1021 at will, which can prevent loss without affecting folding and unfolding. The same is true for the lower support rod 1010, which will not be described in detail here.

[0050] The connecting rope 107 can be an elastic rope or an inelastic rope. When it is an inelastic rope, the length can be adjusted, and different lengths correspond to the unfolded state or folded state of the moon chair. For example, in the folded state, the length of the inelastic rope is longer, and the upper support rod 1000 and the upper connector 1021 are not fixed at this time, and can be folded at will; when it is necessary to unfold, the length of the inelastic rope is shortened (for example, the end of the inelastic rope is knotted), so that the distance between the upper support rod 1000 and the upper connector 1021 is shortened, and the upper support rod 1000 and the upper connector 1021 are fixed at this time, and the unfolding is completed.

[0051] In some embodiments, the upper support rod 1000 and / or the lower support rod 1010 are detachable combination rods. The connection method between the support rods of the combination rod is the same as the connection method of the upper support rod 1000 and the upper connector 1021, and adopts existing connection methods, such as threaded connection, sleeve connection, movable marble (not shown in the figure) and marble hole (not shown in the figure) clamping.

[0052] Preferably, when there are four upper support rods 1000 or four lower support rods 1010, the two front support rods are shorter and the two rear support rods are longer, so that the moon chair can fit the buttocks, waist or back of the human body. The upper support rods 1000 and the lower support rods 1010 can be in various forms such as round tubes, square tubes, triangular tubes or polygonal tubes, which are not limited here.

[0053] In some embodiments, the bottom support assembly 10 also includes a pipe plug 108, which can block the end of the lower support rod 1010 or the upper support rod 1000 to prevent the entry of foreign matter or dust. In addition, in addition to blocking the end of the lower support rod 1010, the pipe plug 108 can also fine-tune the height of the moon chair and reduce shock and noise. For example, the pipe plug 108 is threadedly connected to the lower support rod 1010, and the height of the moon chair can be fine-tuned by adjusting the screwing position. For another example, the pipe plug 108 is an existing elastic buckle that can be inserted into the lower support rod 1010, and different gears correspond to multiple fine-tuning heights of the moon chair.

[0054] In some embodiments, the support rods (including the upper support rod 1000 and the lower support rod 1010 ) may be made of a lightweight but high-strength material, such as carbon fiber, aluminum alloy, titanium alloy, and magnesium alloy.

[0055] Embodiment 2

[0056] This embodiment provides a bottom support assembly 10 for a moon chair. The same points as those in the first embodiment are not repeated here. The difference is that:

[0057] In some embodiments, Figures 7 and 8As shown, the swing assembly includes an elastic pad 1041 and a tension spring (not shown in the figure); the elastic pad 1041 is located between the upper connecting seat 102 and the lower connecting seat 103, and is pressed by the upper connecting seat 102; the tension spring is located on the front side of the elastic pad 1041; the upper and lower ends of the tension spring are respectively fixed to the upper connecting seat 102 and the lower connecting seat 103. The elastic pad 1041 can improve the buffering and elasticity of the swing, and the tension spring is used to provide rebound force. The tension spring is stretched during installation, so that the upper support assembly 100 is slightly tilted toward the front side; when the user leans back on the seat cushion, the moon chair tends to swing backward; when the upper support assembly 100 swings backward, the tension spring is in a stretched state, and the tension of the tension spring prompts the upper support assembly 100 to swing forward; thereby realizing the back and forth swing of the moon chair. The elastic pad 1041 refers to a component that improves the rebound force, such as elastic rubber, elastic plastic, elastic metal (such as copper alloy) and composite material (such as fiber reinforced composite material).

[0058] In some embodiments, Figure 8 As shown, an arc-shaped groove 10410 is provided in the middle of the elastic pad 1041 to fit with the screw 1060 to prevent the elastic pad 1041 and the upper connecting seat 102 or the lower connecting seat 103 from moving relative to each other during the swinging of the moon chair.

[0059] In some embodiments, Figure 6 As shown, multiple installation positions of the tension spring can be set on the upper connecting seat 102 and the lower connecting seat 103, and the initial lengths of the tension springs corresponding to the multiple installation positions are different. For example, the upper connecting seat 102 or the lower connecting seat 103 can be provided with multiple second hanging ears 1022, and different initial lengths of the tension springs can correspond to multiple tensions, so that the upper support assembly 100 has different initial positions, and can also correspond to different swing ranges of the moon chair. For example, when the initial length of the tension spring is longer, the tension spring is in an extended state. When the tension spring is set on the front side, the initial position of the moon chair is tilted forward. At this time, a larger thrust is required to make the moon chair swing backward when leaning back; on the contrary, when the moon chair swings back and rebounds, it can rebound quickly (swing forward quickly) due to the large tension. For another example, when the initial length of the tension spring is close to the length of the natural extension of the tension spring, the rebound force decreases and the moon chair swings slowly.

[0060] Embodiment 3

[0061] This embodiment provides a bottom support assembly 10 for a moon chair. The same points as those in the first embodiment are not repeated here. The difference is that:

[0062] In some embodiments, Figure 10 to Figure 11As shown, the swing assembly includes an elastic pad 1041 and a compression spring 1043; the elastic pad 1041 and the compression spring 1043 are both located between the upper connecting seat 102 and the lower connecting seat 103, and are pressed by the upper connecting seat 102; the compression spring 1043 is located at the rear side of the elastic pad 1041; at least one of the upper connecting seat 102 and the lower connecting seat 103 is fixed to the compression spring 1043. The compression spring 1043 is arranged at the rear side of the elastic pad 1041; when the upper supporting assembly 100 swings backward, the compression spring 1043 is in a compressed state, and the elongation tendency of the compression spring 1043 causes the upper supporting assembly 100 to swing forward; thereby realizing the back and forth swinging of the moon chair.

[0063] In some embodiments, the compression spring 1043 is compressed during installation, causing the moon chair to tilt forward. When the user sits on the moon chair, he only needs to lean back as far as possible and the moon chair can rock backward by its own gravity. The elongation tendency of the compressed compression spring 1043 causes the moon chair to rock forward. By adding the compression spring 1043 at the rear end, a greater rebound force can be provided, allowing the moon chair to rebound quickly.

[0064] The working principle of the compression spring 1043 is similar to that of the tension spring. The difference is that when the moon chair swings, the compression spring 1043 is mainly subjected to pressure, and the elastic force of the swing is provided by the elongation tendency of the compression spring 1043 after contraction; the tension spring is mainly subjected to tension, and the elastic force of the swing is provided by the contraction tension of the tension spring after stretching.

[0065] This embodiment also provides a moon chair, such as Figures 1 to 11 As shown, the moon chair includes a seat cushion and the bottom support assembly 10 as described in the above embodiment. Since the moon chair includes the bottom support assembly 10 as described in the above embodiment, it at least has the advantages of the bottom support assembly 10, that is, the upper connecting seat 102 is connected to each upper support rod 1000 at the same time, and the lower connecting seat 103 is connected to each lower support rod 1010 at the same time, that is, the upper connecting seat 102 and the lower connecting seat 103 can be connected to the rods on both sides at the same time, and the degree of reuse is high. At the same time, the upper support assembly 100 and the lower support assembly 101 are both in a folded shape, which is conducive to saving space. Combined with the reuse of the upper connecting seat 102 and the lower connecting seat 103, the overall structure is more compact.
