Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below. In addition, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0033] The overall structure diagram of the flip support device of the utility model is as follows Figure 1 As shown, the flip support device includes a flip assembly 1 and a support assembly 2, and the support assembly 2 is connected to the flip assembly 1. The flip assembly 1 includes a mounting bracket 11 and a connecting bracket 12, and the connecting bracket 12 can be flipped upward relative to the mounting bracket 11 to prop up the flip assembly 1, or can be flipped upward and then flipped downward to fold the flip assembly 1.

[0034] As a preferred embodiment, the flip assembly 1 also includes the first connecting rod 13, one end of the first connecting rod 13 is hinged to the mounting bracket 11, and the other end of the first connecting rod 13 is hinged to the connecting bracket 12. Since the first connecting rod 13 is hinged between the mounting bracket 11 and the connecting bracket 12, the connecting bracket 12 can be flipped relative to the mounting bracket 11 by the first connecting rod to open the flip assembly 1, or fold the flip assembly 1.

[0035] The support assembly 2 is used to support the flip assembly 1 after the connecting bracket 12 flips and opens the flip assembly 1, so as to prevent it from falling back after being opened. The support assembly 2 includes a second support rod 14, a support rod 21 and a rotating block 22, one end of the second connecting rod 14 is hinged to the mounting bracket 11, and the other end of the second connecting rod 14 is hinged to the connecting bracket 12, one end of the support rod 21 is hinged to the second connecting rod 14 through a pin 23, and the other end of the support rod 21 is hinged to the connecting bracket 12, the rotating block 22 is sleeved on the pin 23, the rotating block 22 is located on the side of the support rod 21 away from the second connecting rod 14, and the rotating block 22 and the pin 23 can rotate relative to each other; a guide groove 211 is provided on the support rod 21, and the rotating block 22 moves along the guide groove 211. When the connecting bracket 12 is flipped upward to a predetermined angle, the rotating block abuts against the support rod to lock the connecting bracket, and the connecting bracket is further flipped upward to open the connecting bracket, the rotating block is unlocked from the support rod, and the connecting bracket can be folded relative to the mounting bracket.

[0036] When the connecting bracket 12 is flipped upward and stretched to a predetermined angle, the rotating block 22 first moves along the guide groove 211 in the first direction, and then rotates relative to the pin 23 until it abuts against the support rod 21 to lock the connecting bracket 12. The connecting bracket 12 is further flipped upward, and the rotating block 22 is disengaged from the support rod 21 to release the lock. The connecting bracket 12 is then flipped downward, and the support rod 21 causes the rotating block 22 to rotate until it can move along the guide groove 211 in the second direction until the connecting bracket 12 is folded and reset, that is, the flip assembly 1 is folded and reset, and the first direction and the second direction are opposite. Fig.12 This is a diagram of the flip assembly 1 after being folded.

[0037] Specifically, Figure 2 As shown, the two opposite ends of the rotating block 22 are symmetrically provided with notches 221. When the connecting bracket 12 is flipped upward to open to a predetermined angle, one of the notches 221 abuts against the support rod 21 to lock the connecting bracket 12. In an optional embodiment, the notch 221 is formed by connecting two symmetrical inclined surfaces 2211. Of course, in other embodiments, the notch 221 can also be formed by connecting other types of curved surfaces, such as curved surfaces or arc surfaces. Figure 3The structure diagram of the support rod 21 is shown. The support rod 21 is provided with a first flange 212 and a second flange 213. The first flange 212 is consistent with the extension direction of the guide slot 211. The first end of the first flange 212 is aligned with the first end of the guide slot 211. The length of the first flange 212 is less than the length of the guide slot 211, that is, there is a distance difference between the second end of the first flange 212 and the second end of the guide slot 211. The second flange 213 is arranged on the support rod 21 away from the end of the connecting bracket 12. Specifically, in combination with Figure 4 As shown, before the connecting bracket 12 is turned upward and stretched to a predetermined angle, the connecting bracket 12 is first turned to a first angle in sequence. and the first angle When the connecting bracket 12 is flipped to the first angle During the process, the rotating block 22 moves along the guide groove 211 and the first flange 212 in the first direction at the same time. Since the length of the first flange 212 is less than the length of the guide groove 211, when the first angle is reached, When the rotating block 22 is disengaged from the first flange 212, the other notch 221 of the rotating block 22 abuts against the second flange 213; since the notch 221 includes two symmetrical inclined surfaces 2211, after the rotating block 22 is disengaged from the first flange 212, one of the inclined surfaces 2211 of the other notch 221 of the rotating block 22 abuts against the second flange 213; further flip the connecting bracket 12 upward to the second angle When reaching the second angle Before, the second flange 213 pushes one of the inclined surfaces 2211 of the other notch 221 of the rotating block 22 to push the rotating block 22 to rotate, and at this time, the rotating block 22 rotates in the counterclockwise direction; Figure 5 As shown, the connecting bracket 12 is flipped to a second angle When the second notch 221 of the rotating block 22 is in contact with the second flange 213, the rotating block 22 stops rotating. Then, the connecting bracket 12 is turned down to a predetermined angle. like Figure 7 As shown, the first flange 212 and one of the notches 221 of the rotating block 22 abut against each other to lock the connecting bracket 12, and the first angle and the second angle are greater than the predetermined angle

[0038] It should be noted that if Figure 6 As shown, the connecting bracket 12 is then turned downward to a predetermined angle. Before the first flange 212 is turned, it abuts against one of the inclined surfaces 2211 of one of the notches 221 of the rotating block 22, and the connecting bracket 12 is further turned downward. The first flange 212 pushes one of the inclined surfaces 2211 of one of the notches 221 of the rotating block 22, thereby pushing the rotating block 22 to rotate. At this time, the rotating block 22 rotates in the counterclockwise direction; the connecting bracket 12 is turned to a predetermined angle. When the rotating block 22 rotates until the other inclined surface 2211 of one of the notches 221 abuts against the first flange 212, the connecting bracket 12 is locked. At this time, since the rotating block 22 rotates until the other inclined surface 2211 of one of the notches 221 abuts against the first flange 212, the support rod 21 stops between the connecting bracket 12 and the second connecting rod 14, and the connecting bracket 12 cannot continue to flip downward. The connecting bracket 12 is locked, and even without external support, the flip assembly 1 will not fold due to the support of the support rod 21 between the connecting bracket 12 and the second connecting rod 14, thereby improving the reliability of the flip support device.

[0039] In one embodiment, the first flange 212 is arranged along the side of the support rod 21, and the first flange 212 is perpendicular to the support rod 21. When the connecting bracket 12 is flipped upward and stretched to a predetermined angle, the inner side surface of the first flange 212 fits against another inclined surface 2211 of one of the notches 221 of the moving block. The second flange 213 is arranged at an angle relative to the extension direction of the support rod 21, and the second flange 213 is perpendicular to the support rod 21. When another inclined surface 2211 of another notch 221 of the rotating block 22 fits against the inner side surface of the second flange 213, the rotating block 22 stops rotating.

[0040] When the flip support device needs to be folded, when the rotating block 22 is rotated to the state where the other inclined surface 2211 of one of the notches 221 abuts against the first flange 212, the connecting bracket 12 is flipped upward until the first flange 212 is disengaged from the other inclined surface 2211 of one of the notches 221 of the rotating block 22 to release the lock, and at the same time, one side of the rotating block 22 abuts against the second flange 213, as shown in FIG. Figure 8 As shown; further flip the connecting bracket 12 upward, the second flange 213 pushes the rotating block 22 to rotate by pushing one side of the rotating block 22, and the rotating block 22 rotates counterclockwise until the other side of the rotating block 22 is opposite to the first flange 212, as shown Fig. 9Further flip the connecting bracket 12 downward, the first flange 212 and the other side of the rotating block 22 abut against each other, as shown Fig.10 as shown; Fig.11 As shown, the connecting bracket 12 is continuously flipped downward, and the first flange 212 pushes the other side of the rotating block 22 to push the rotating block 22 to rotate until the other side of the rotating block 22 gradually fits with the first flange 212. At this time, the rotating block 22 rotates in a counterclockwise direction. In the process of flipping the connecting bracket 12 downward, the rotating block 22 can simultaneously move along the first flange 212 and the guide groove 211 in the second direction until the flip assembly 1 is completely folded, as shown. Fig.12 It should be noted here that the first direction and the second direction are opposite directions, but both are along the extending direction of the guide groove 211 .

[0041] As an optional embodiment, a telescopic support rod 15 is provided between the connecting bracket 12 and the mounting bracket 11, and the two ends of the telescopic support rod 15 are respectively hinged to the connecting bracket 12 and the mounting bracket 11. The telescopic support rod 15 provides assistance in the process of propping up the flip assembly 1. For example, the connecting bracket 12 only needs to be flipped down with a slight force, and the telescopic support rod 15 will automatically provide auxiliary propping force to prop up the flip assembly 1, thereby reducing the user's effort and improving the comfort experience. After the flip assembly 1 is propped up, it can also provide support to reduce the pressure on other components and improve the service life. The telescopic support rod 15 can be a pneumatic telescopic rod 15, a spring telescopic rod 15, or a hydraulic telescopic rod 15, or other telescopic support structures.

[0042] The utility model also provides a bed, such as Fig.13 The figure shows a schematic diagram of the overall structure of the bed. The bed includes a bed frame 3, a bed board 4 and the flip support device as described above. The bed board 4 is arranged on the bed frame 3, and the flip support device is connected between the bed frame 3 and the bed board 4, wherein the mounting bracket 11 is installed on the bed frame 3, and the connecting bracket 12 is connected to the bed board 4, and the bed board is flipped and propped up or laid flat relative to the bed frame 3 by the flip assembly 1. For example, when a storage space is provided under the bed board 4 or the floor under the bed board 4 needs to be cleaned, the bed board 4 is flipped, and the flip assembly 1 is propped up, that is, the bed board 4 is propped up. After completion, the bed board 4 is flipped again, and the bed board 4 can be flattened by folding the flip assembly 1, and the support assembly 2 supports the flipped bed board 4.
