Description

Hover buffering hinge assembly Technical field: The utility model relates to the technical field of hinge products, in particular to a hovering buffer hinge assembly. The background technology is as follows: The common horizontal refrigerator hinge in the existing market is generally free of damping effect, and needs to be held all the time by hands in the falling process, otherwise, the refrigerator door can fall rapidly to generate larger door closing sound and impact damage, and hands are easy to be clamped and hurt when people are not careful. In addition, there are some horizontal refrigerator hinges with damping and falling buffering in the prior art, but in general, these horizontal refrigerator hinges have no multi-angle hovering function, i.e. if the refrigerator door is required to be stopped all the time or opened to the maximum angle when the refrigerator is opened, this is time-consuming, laborious and inconvenient for one-hand operation. In order to solve the problems, a power-assisted hinge, a horizontal refrigerator and a working method (application number 202210880969.7) are proposed, wherein the power-assisted hinge comprises a hinge head, a connecting rod, a supporting seat, a hinge seat and springs, the two ends of the connecting rod are connected with the hinge head and the supporting rod, when the hinge head is turned over, the rotating end of the connecting rod is limited by a connecting shaft on the hinge head to limit the turning ability of a box cover, when the horizontal refrigerator is closed, the springs are under the compressed state and are influenced by a magnetic attraction device and cannot push the hinge head and the box cover to move, the box cover moves and is turned upwards together with the hinge head, the connecting rod is driven by the first connecting shaft to turn upwards, the supporting rod is driven by the connecting rod to move upwards, at the moment, the springs start to stretch downwards, the springs upwards stretch, the supporting rod also moves upwards through the action of a spring washer to form box opening power assistance, and the larger box cover is convenient to open. When articles are taken out or stored in the horizontal refrigerator, the refrigerator cover can hover due to the assistance of the springs. However, the power-assisted hinge has no buffer effect, so that the box cover falls down rapidly due to the gravity of the box cover in the falling process to generate larger closing sound and impact damage, the risk of hand injury caused by clamping exists, and the use experience of a user cannot be improved. In view of this, the present inventors have proposed the following means. The utility model comprises the following steps: The utility model aims to overcome the defects of the prior art and provides a hovering buffer hinge assembly. In order to solve the technical problems, the hovering buffer hinge assembly comprises a lower hinge, an upper hinge rotatably arranged at the upper end of the lower hinge, an upper spring seat arranged at the lower end of the upper hinge and capable of rotating relative to the upper hinge, a lower spring seat arranged at the middle part or the lower end of the lower hinge and a spring arranged between the lower spring seat and the upper spring seat, wherein the lower spring seat is fixed at the middle part or the lower end of the lower hinge, and a linear damper for buffering is further connected between the lower spring seat and the upper spring seat.
