DETAILED DESCRIPTION
[0031] The present invention is further described in detail below with reference to the accompanying drawings.
[0032] Example 1
[0033] like Figures 1 to 5 A folding accessory is shown, and its main body is provided with a support rod 1 and a bottom plate 2, and a connecting rod assembly 3 is arranged between the support rod 1 and the bottom plate 2. The supporting rod 1 is driven by the connecting rod assembly 3 to complete the unfolding and folding movements.
[0034] The support rod 1 is provided with a cushion 5, and the combination of the cushion 5 and the support rod 1 forms a sofa bed for consumers to use. When the support rod 1 is in an unfolded state, it cooperates with the bottom plate 2 under the action of the connecting rod assembly 3 to form a bed. Figure 4 As shown; the support rod 1 is in the folded state, and it cooperates with the bottom plate 2 under the action of the connecting rod assembly 3 to form a sofa, such as Figure 5 shown.
[0035] The support rod 1 includes a first support rod 110, a second support rod 120 and a third support rod 130. The first support rod 110, the second support rod 120 and the third support rod 130 are respectively hinged to the connecting rod assembly 3. The combination of the first support rod 110, the second support rod 120 and the third support rod 130 makes this folding accessory a three-folding functional accessory.
[0036] The connecting rod assembly 3 is provided with a first connecting rod 310 and a second connecting rod 320, wherein both ends of the first connecting rod 310 and the second connecting rod 320 are hinged to the bottom plate 2 and the first supporting rod 110 respectively. Figure 1 As shown, the second connecting rod 320 is located on the left side of the first connecting rod 310, and the first connecting rod 310 and the second connecting rod 320 are both hinged to the left side of the first support rod 110. The second support rod 120 is placed parallel to the first support rod 110, and the second support rod 120 is hinged to the middle and upper parts of the first connecting rod 310 and the second connecting rod 320 respectively, that is, the first support rod 110 is located above the second support rod 120. Under the joint action of the first connecting rod 310 and the second connecting rod 320, the unfolding and folding linkage process of the first support rod 110 and the second support rod 120 is realized.
[0037] The connecting rod assembly 3 is provided with a fifth connecting rod 350, one end of the fifth connecting rod 350 is hinged to the support rod 1, and the other end is slidably connected to a preset slide groove on the base plate 2. Since the length of the fifth connecting rod 350 is fixed, the height adjustment of the support rod 1 connected to the fifth connecting rod 350 can be achieved by changing the position of the end of the fifth connecting rod 350 in the slide groove, and the fifth connecting rod 350 and the support rod 1 during the folding and lifting process, The space occupied is relatively reduced compared to the rotation, lifting and folding process in the background technology; on this basis, during the movement process of this embodiment, the distance it travels is shorter, so the required adjustment time is less, and the speed of folding adjustment is relatively improved.
[0038] Specifically, the fifth connecting rod 350 is hinged to the right end of the third supporting rod 130, such as Figure 1 As shown, the slide groove is horizontally opened on the bottom plate 2 , and the third support rod 130 is located below the second support rod 120 .
[0039] In this embodiment, the connecting rod assembly 3 is further provided with a fourth connecting rod 340, one end of the fourth connecting rod 340 is hinged to the bottom plate 2, and the other end is slidably connected to a preset slide groove on the third support rod 130, the slide groove is horizontally opened on the third support rod 130, and the fourth connecting rod 340 and the fifth connecting rod 350 are cross-arranged, such as Figure 1 As shown, the intersection of the fourth connecting rod 340 and the fifth connecting rod 350 is hinged through a connecting shaft, and the smooth rise and fall of the third support rod 130 is achieved by adjusting the position of the sliding groove of the fifth connecting rod 350 on the base plate 2 and the position of the sliding groove of the fourth connecting rod 340 on the third support rod 130.
[0040] A third connecting rod 330 is disposed between the second connecting rod 320 and the fourth connecting rod 340. Figure 1 or Figure 2 As shown, both ends of the third link 330 are hinged to the second link 320 and the fourth link 340 respectively. The setting of the third link 330 combines the movements of the second link 320 and the fourth link 340 to achieve linkage, thereby achieving a linkage folding effect among the first support rod 110, the second support rod 120 and the third support rod 130.
[0041] Furthermore, one end of the third connecting rod 330 close to the second connecting rod 320 is configured as a bent end 331. Figure 1 or Figure 2 As shown, the purpose of setting the bent end 331 is to avoid interference between the second link 320 and the fourth link 340 during the folding process, so that the first support rod 110, the second support rod 120 and the third support rod 130 can be folded more thoroughly, as shown in FIG. Figure 3 As shown. Used to further reduce the footprint of the sofa bed using this folding accessory.
[0042] The bottom plate 2 is configured as a stepped structure. Figures 1 to 3 As shown, the stepped structure bottom plate 2 is provided with an upper bottom plate 210 and a lower bottom plate 220, the upper bottom plate 210 and the lower bottom plate 220 are integrally formed, the first connecting rod 310 and the second connecting rod 320 are hinged to the upper bottom plate 210, the fourth connecting rod 340 and the fifth connecting rod 350 are hinged to the lower bottom plate 220, and the stepped structure bottom plate 2 is used to realize that the upper surfaces of the first support rod 110, the second support rod 120 and the third support rod 130 are in the same horizontal plane after being unfolded, as shown in FIG. Figure 2 shown.
[0043] In this embodiment, the connecting rod assembly 3 is provided with a booster arm 4 , which can promote the movement of the connecting rod assembly 3 .
[0044] Specifically, the booster arm 4 includes a first booster arm 410, which is disposed between the first connecting rod 310 and the second connecting rod 320, and the two ends of the first booster arm 410 are respectively hinged to the first connecting rod 310 and the second connecting rod 320. Figure 1 As shown, the first booster arm 410 is preferably but not limited to a gas spring. Under the action of the first booster arm 410, the movement of the first connecting rod 310 and the second connecting rod 320 is smoother and easier.
[0045] The booster arm 4 further includes a second booster arm 420, which is disposed between the fourth connecting rod 340 and the fifth connecting rod 350, and the two ends of the second booster arm 420 are respectively hinged to the fourth connecting rod 340 and the fifth connecting rod 350. Figure 1 As shown, the second booster arm 420 can promote the linkage between the fourth link 340 and the fifth link 350 .
[0046] The second booster arm 420 is configured as a gas spring. The force output by the gas spring can help the fourth connecting rod 340 and the fifth connecting rod 350 to move, which not only makes the movement process smoother and easier, but also has a labor-saving effect.
[0047] In summary, when it is necessary to unfold the folding accessory, a rightward force is applied to the first support rod 110, and the first connecting rod 310 and the second connecting rod 320 are driven to rotate by driving the first support rod 110. The rotating first connecting rod 310 and the second connecting rod 320 drive the second support rod 120 to move. At the same time, the third connecting rod 330 connects the second connecting rod 320 and the fourth connecting rod 340, drives the fourth connecting rod 340 and the fifth connecting rod 350 to move, and pushes the third support rod 130 to move, and finally presents the following. Figure 2 If you need to fold this foldable accessory, just apply a left force to the first support rod 110 to form a Figure 3 The folded state shown has a simple structure and is easy to operate.
[0048] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that various modifications and variations are possible for those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
