[0030] See Figures 1 to 3 As shown, a hinge 1 is shown to include: a fastening member 11, a shaft body 12, and a rotating motor 13. Among them, the rotating motor 13 drives the fastening member 11 to rotate about a rotating shaft 111, and finally presents two states, namely, a state of being fastened to the shaft body 12 and a state of being disengaged from the shaft body 12. In the state where the fastening member 11 is fastened to the shaft body 12, the fastening member 11 no longer rotates about the rotating shaft 111 but rotates about the shaft body 12.
[0031] In the state where the fastening member 11 is fastened to the shaft body 12, the fastening member 11 rotates about the shaft body 12, which specifically means that: the whole including the fastening member 11, the rotating shaft 111, and the rotating motor 13 can rotate about the shaft body 12 through the fastening of the fastening member 11 and the shaft body 12. During the process of the whole including the fastening member 11, the rotating shaft 111, and the rotating motor 13 rotating about the shaft body 12, the fastening member 11 cannot rotate about the rotating shaft 111.
[0032] The rotating motor 13 provides kinetic energy for the rotation of the fastening member 11. Similarly, the output shaft of the rotating motor 13 can also fix the fastening member 11 in the rotating direction in a fixed state, thereby forming a structure in which the rotating motor 13 controls the rotation and stop of the fastening member 11 around the rotating shaft 111; when the fastening member 11 and the shaft body 12 are in a fastened state, the output shaft of the rotating motor 13 remains stationary, and a situation can be formed where the fastening member 11 cannot rotate around the rotating shaft 111 but rotates around the shaft body 12.
[0033] See Figures 2 to 3 As shown, the fastening member 11 has a fastening portion 112 and two open portions 113. The two open portions 113 are respectively connected to both sides of the fastening portion 112. In the state where the fastening member 11 and the shaft body 12 are fastened, the shaft body 12 can be embedded in the fastening portion 112. One end of each of the two open portions 113 is connected to both ends of the fastening portion 112 respectively. The other ends of the two fastening portions 112 extend in a direction away from the fastening portion 112, and an open mouth 114 is formed between the other ends of the two fastening portions 112. A fastening channel 115 is formed from the open mouth 114 to the fastening portion 112. The fastening channel 115 is on the base circle formed with the rotating shaft 111 as the center.
[0034] During the fastening process of the fastening member 11 and the shaft body 12, the fastening member 11 rotates around the rotating shaft 111, so that the shaft body 12 enters the fastening channel 115 from the open mouth 114 and is then fastened to the fastening portion 112, forming the fastening of the fastening member 11 and the shaft body 12; during the separation process of the fastening member 11 and the shaft body 12, the fastening member 11 rotates around the rotating shaft 111, so that the shaft body 12 enters the fastening channel 115 from the fastening portion 112 and finally exits from the open mouth 114, realizing the separation of the fastening member 11 and the shaft body 12.
[0035] The width of any cross-section on the fastening channel 115 is not less than the size of the shaft body 12. Specifically, in order to facilitate the entry of the shaft body 12 into the fastening channel 115, on any cross-section perpendicular to the extending direction of the fastening channel 115, the width of the fastening channel 115 should be greater than or equal to the width of the shaft body 12 at the entry into the fastening channel 115; preferably, the two open portions 113 from the fastening portion 112 to the open mouth 114 are away from each other, so that the fastening channel 115 shows a gradually increasing width, in order to facilitate the shaft body 12 to gradually penetrate into the fastening portion 112 from the open mouth 114.
[0036] The fastening member 11 further has an upper end portion 116, a connecting portion 117, and a tail end portion 118. The connecting portion 117 connects the upper end portion 116 and the tail end portion 118. The rotating shaft 111 is provided on the upper end portion 116. A fastening portion 112 is formed on one side surface of the connecting portion 117. A fastening channel 115 is formed between the upper end portion 116 and the tail end portion 118. It should be noted that the upper end portion 116, the connecting portion 117, and the tail end portion 118 are all streamlined structures with arcs. Compared with the angular structure, the area swept by the first fastening portion 112 with an arc during rotation is smaller, saving space. In a preferred embodiment, it is set as Figures 2 to 3 shown in the shape of a tama jade.
[0037] Specifically, in order to facilitate the rotation of the fastening member 11 around the shaft body 12, the outer edge of the part of the shaft body 12 that cooperates with the fastening member 11 is set to be circular, and the fastening portion 112 is in an arc shape, and the fastening portion 112 fits with the outer edge of the shaft body 12. In order to facilitate the separation of the shaft body 12 from the fastening member 11, the shape of the fastening portion 112 is an arc not greater than 1 / 2.
[0038] Refer to Figure 4 shown, which shows a refrigerator with a double - way opening door. The refrigerator has a door and a cabinet body. A hinge 1 is used between the door and the cabinet body. Among them, both sides of the door and both sides of the cabinet body are respectively connected by no less than one group of hinges 1. Preferably, as Figure 4 shown, an upper - left - corner hinge 1A, an upper - right - corner hinge 1B, a lower - left - corner hinge 1C, and a lower - right - corner hinge 1D are respectively arranged at the upper - left corner, upper - right corner, lower - left corner, and lower - right corner of the refrigerator. Specifically, the two sides mentioned above are Figure 4 the left and right sides in
[0039] That is, the upper - left - corner hinge 1A and the lower - left - corner hinge 1C are hinges 1 on the same side; the upper - right - corner hinge 1B and the lower - right - corner hinge 1D are hinges 1 on the same side.
[0040] The hinges 1 on the same side of the cabinet body are two in number, and the installation directions of the two hinges 1 on the same side of the cabinet body are opposite. Specifically, refer to Figure 5As shown, the upper left corner fastening member of the upper left hinge 1A is installed on the box body, and the upper left shaft body 12A of the upper left hinge 1A is installed on the door of the box; the lower left corner fastening member of the lower left hinge 1C is installed on the door of the box, and the lower left shaft body 12C of the lower left hinge 1C is installed on the box body; the upper right corner fastening member of the upper right hinge 1B is installed on the box body, and the upper right shaft body 12B of the upper right hinge 1B is installed on the door of the box; the lower right corner fastening member of the lower right hinge 1D is installed on the door of the box, and the lower right shaft body 12D of the lower right hinge 1D is installed on the box body; such a setting can more stably realize the connection between the door of the box and the box body.
[0041] On both sides of the door of the box, there are door handles 2 for opening the door of the box. Here, the door handle 2 is not limited to a handle and can refer to any specific structure for opening the door of the refrigerator. Each door handle 2 is provided with a touch sensor 3. When the user touches the door handle 2, the touch sensor 3 receives the touch signal on the touched door handle 2 and drives the fastening member 11 and the shaft body 12 of the hinge 1 on the same side of the refrigerator to disengage and drives the fastening member 11 and the shaft body 12 of the hinge 1 on the opposite side of the refrigerator to engage. At this time, the user can open the door of the refrigerator from the side of the door handle 2 that was touched before.
[0042] Between each side of the box body and the corresponding side of the door of the box, there is a distance sensor 4 for measuring whether the door of the box is opened; see Figure 6 As shown, when the user touches the door handle 2, the touch sensor 3 receives the touch signal on the touched door handle 2; at this time, the distance sensor 4 measures whether the door of the box is in the open state according to the distance between the door of the box and the box body. When it is detected that any side is in the open state, no operation is performed, that is, the hinge 1 remains unchanged; when it is detected that both sides are in the unopened state, an operation is performed. The specific operation is: the hinge 1 on the same side as the touch sensor that releases the touch signal is relaxed, that is, the fastening member 11 and the shaft body 12 of the hinge 1 on the same side are disengaged; the hinge 1 on the other side of the touch sensor that releases the touch signal is locked, that is, the fastening member 11 and the shaft body 12 of the hinge 1 on the other side are engaged.
[0043] For example: in the normal closed state of the refrigerator, when the user needs to open the door from the left side, the touch sensor 3 on the door handle 2 of the left side door of the box will be touched. At this time, after the distance sensor 4 measures that both sides of the door of the box are in the unopened state according to the distance between the door of the box and the box body, the upper left hinge 1A and the lower left hinge 1C are relaxed, and the upper right hinge 1B and the lower right hinge 1D are locked, so that the refrigerator door can be opened from the left side.
[0044] Specifically, the following special states will be encountered in the operation of this device:
[0045] Special state 1: When touch signals from both sides are received simultaneously, the hinges 1 on both sides of the refrigerator remain in their current states without change.
[0046] Special state 2: When two touch signals are continuously received within the set time, the first touch signal shall prevail.
[0047] In the normal use state, the hinges 1 on both sides of the refrigerator always maintain the state that one hinge 1 is loose and the other hinge 1 is locked; when the user opens the refrigerator door for the first time, the hinges 1 on both sides of the refrigerator maintain the current state until the user touches the touch sensor 3 on the other side next time, and then the state of the hinge 1 changes. In this way, during subsequent use, the refrigerator door can be opened from the side that was opened previously even if the sensor is not touched.
[0048] See Figure 7 As shown, the shaft body 12 is fixedly arranged on the shaft body fixing part 121. The shaft body fixing part 121 is provided with a shaft body installation groove 1211. The shaft body 12 is arranged in the shaft body installation groove 1211. The arrangement of the shaft body installation groove 1211 leaves a part of the space, which is convenient for the rotation of the fastening part 11; the fastening part connecting part 131 is arranged between the rotating motor 13 and the fastening part 11. A matching hole is provided on the fastening part connecting part 131. The rotating shaft 111 penetrates through the matching hole, and the fastening part 11 can rotate relative to the fastening part connecting part 131; wherein the fastening part connecting part 131 is fixedly connected to one of the box body or the box door; the shaft body fixing part 121 is fixedly connected to the other of the box body or the box door.
