[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Refer to Figures 1 - 12 , the opening and closing structure of the present up - turning device includes a hinge device that opens and closes on the up - turning device through a swivel arm assembly. Among them, the up - turning device is fixedly connected to the cabinet X, and the hinge device is detachably connected to the panel Y.

[0029] Specifically, the swivel arm assembly includes a first swivel arm 1 and a second swivel arm 2, which are independently arranged between the first swivel arm 1 and the second swivel arm 2; the up - turning device at least includes a fixed bracket 3 and an elastic component A arranged on the fixed bracket 3, and the fixed bracket 3 is fixedly connected to the cabinet X; the hinge device at least includes a connecting arm 4 and a fixed base 5 that can be disassembled and assembled on the connecting arm 4, the fixed base 5 is fixedly connected to the panel Y, and the panel Y can be disassembled and assembled on the connecting arm 4 through the fixed base 5.

[0030] One end of the first swing arm 1 and the second swing arm 2 is respectively rotatably connected to the connecting arm 4, and the other end is respectively rotatably connected to the fixed bracket 3; when the first swing arm 1 or the second swing arm 2 rotates, it elastically interacts with the elastic component A; the hinge device is elastically opened and closed in a translational manner on the upward-flipping device through the cooperation of the first and second swing arms and the elastic component A; the assembly angle of the connecting arm 4 and / or the fixed base 5 remains substantially unchanged when the hinge device is opened and closed.

[0031] That is, the panel Y can be opened and closed in a translational manner on the cabinet body X, and its assembly angle with the hinge device remains substantially unchanged when it is opened and closed. The opening and closing process of the panel Y in this embodiment is as Figures 10 - 12 shown. When assembled, it is vertically detachably mounted on the connecting arm 4 through the fixed base 5, and it always maintains vertical translation during the opening and closing process, so as to effectively avoid the problem that the panel Y in the prior art is opened in an upward-flipping manner, which requires a large space for operation, and is easy to collide with the user when opened, causing injuries to the user, etc., thereby reducing the opening and closing space of the panel Y and improving the use safety.

[0035] Since a distance is formed between the first connecting arm transfer portion 6 and the second connecting arm transfer portion 7, and between the first bracket transfer portion 8 and the second bracket transfer portion 9, the first swing arm 1 and the second swing arm 2 respectively rotatably connected to them form a distance difference when rotating, which not only avoids the collision between the two when rotating, but also reasonably utilizes the space, further reduces the opening and closing space of the panel Y, and improves the space utilization rate.

[0040] That is, after the panel Y is assembled, it can realize up-and-down, front-and-back, and left-and-right position adjustments relative to the cabinet body X, so that the panel Y and the cabinet body X can achieve a tightly closed effect, making the appearance of the product more neat and beautiful.

[0041] There are two up-flipping devices and hinge devices respectively, and the two up-flipping devices and hinge devices are arranged left and right; wherein, a synchronizing rod 19 is further arranged between the left and right up-flipping devices, and the synchronizing rod 19 is detachably arranged between the left and right first rotating arms 1 or the second rotating arms 2; the left and right first rotating arms 1 or the second rotating arms 2 rotate synchronously and / or simultaneously through the synchronizing rod 19, so as to realize the synchronous and / or simultaneous translational elastic opening and closing of the left and right hinge devices on the left and right up-flipping devices.

[0042] The left and right up-flipping devices are respectively fixedly arranged on the left and right inner side walls of the cabinet body X, and the left and right hinge devices are respectively detachably connected to the left and right sides of the panel Y. The up-flipping devices and hinge devices are arranged in a left-and-right manner, and at the same time, the synchronizing rod 19 is used to enable the left and right hinge devices to be synchronously and / or simultaneously translated and elastically opened and closed on the left and right up-flipping devices, thereby ensuring that the left and right sides of the panel Y can be smoothly opened and closed on the cabinet body X, reducing the imbalance of the left and right sides of the panel Y during opening and closing, and preventing the panel Y from being unable to be truly opened and closed on the cabinet body X or getting stuck or not running smoothly during opening and closing.

[0043] A transmission rod 20 is provided between the first rotating arm 1 or the second rotating arm 2 and the elastic component A; when the first rotating arm 1 or the second rotating arm 2 rotates, it elastically interacts with the elastic component A through the transmission rod 20.

[0044] Furthermore, an elastic adjustment component B is provided on the fixed bracket 3. The elastic adjustment component B at least includes an adjustment bracket 21 and a movable member 22 movably arranged on the adjustment bracket 21 in an adjustable manner; one end of the transmission rod 20 is rotatably connected to the second rotating arm 2, and the other end is rotatably connected to the adjustment bracket 21; one end of the elastic component A is elastically rotatably connected to the fixed bracket 3, and the other end is elastically rotatably connected to the movable member 22, and realizes elastic force adjustment when the movable member 22 moves; the hinge device is elastically opened and closed in a translational manner on the upward-flipping device through the cooperation of the first and second rotating arms, the transmission rod 20, the elastic adjustment component B, and the elastic component A.

By setting the elastic member 25 in a sleeved manner at both ends, it can ensure that the elastic member 25 will not have any displacement problems during operation, improve the working stability of the elastic member 25, and at the same time make the elastic force generated by the elastic member 25 more concentrated and reduce elastic force waste.

Since the elastic force of the elastic member 25 is adjustable, the user can arbitrarily adjust the elastic force generated by the elastic member 25 according to the weight of the panel Y, so that the panel Y can achieve a uniform speed, or uniform acceleration, or deceleration opening and closing effect.

[0047] A limiting portion 27 is provided on the fixed bracket 3, and the limiting portion 27 has a certain elasticity or plasticity; when the hinge device is elastically opened in a translational manner to a certain position, the second rotating arm 2 acts on the limiting portion 27 in a limiting manner to limit the opening position of the hinge device relative to the upward-flipping device. Since the limiting portion 27 has elasticity or plasticity, it can play a buffering role in the rotation of the second rotating arm 2, reduce the noise generated when the panel Y is opened, and at the same time use the limiting effect between the second rotating arm 2 and the limiting portion 27 to ensure that the panel Y can only be opened relative to the cabinet body X within a specified position, ensuring the use safety of the product.

[0048] The fixed bracket 3 is further provided with a damper 28, which is an automatic reset damper or a non-automatic reset damper; when the hinge device is closed to a certain position, it acts on the damper 28 through the first rotating arm 1 or the second rotating arm 2, and drives the damper 28 to compress to generate a damping force, so as to realize the translational elastic damping closing of the hinge device on the upward turning device. The use of the damper 28 can reduce the collision and noise generated between the panel Y and the cabinet body X when closing, further ensure the use safety of the product, and improve the use experience of the user at the same time.
