Detailed ways

In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present application, the present application will be described in detail below with reference to the drawings and specific implementation modes.

Referring to FIGS. 1 to 4 , an embodiment of the present application provides a hinge 100 . The hinge 100 includes a hinge shaft 110 and two hinge members 120 that are hinged to each other through the hinge shaft 110 . The hinge 120 includes a first hinge part 122 and a second hinge part 123 . One end of the first hinge part 122 is connected to the hinge shaft 110 , one end of the second hinge part 123 is connected to the other end of the first hinge part 122 , and the second hinge part 123 is relative to the The first hinge part 122 is bent in the folding direction of the hinge part 120 , and the second hinge part 123 is used for connecting with external objects. Optionally, the first hinge part 122 and the second hinge part 123 may adopt an integrated structure, or may be fixedly connected to each other through a split structure. The second hinge part 123 is used to connect with external objects, including direct connection and indirect connection.

The folding direction is the movement direction of the hinge member 120 during the folding process of the hinge 100 . Corresponding to the folding direction, the hinge 100 also has an unfolding direction, and the unfolding direction is the movement direction of the hinge 120 during the unfolding process of the hinge 100 . Taking the hinge shown in Figure 1 as an example, the folding and unfolding directions of the hinge on the left side in Figure 1 are counterclockwise and clockwise respectively, and the folding and unfolding directions of the hinge on the right side in Figure 1 are clockwise respectively. Clockwise and counterclockwise.

In fact, one end of the two hinge parts 120 can be hinged to each other through the hinge shaft 110 , a part of the hinge part 120 close to the hinge shaft 110 forms the first hinge part 122 , and the hinge part 120 is far away from the hinge axis. A part of 110 is bent in the folding direction of the hinge 120 relative to the first hinge part 122 to form the second hinge part 123 .

When the two second hinge parts 123 rotate to be parallel to each other or close to a parallel state, the two first hinge parts 122 gradually diverge from each other while extending from the hinge axis 110 to the second hinge part 123 , forming a The distance gradually increases until it connects with the second hinge part 123. As shown in Figures 1 and 2, it provides an escape space for the two second hinge parts 123, and also provides space for the two second hinge parts 123 connected to the second hinge part 123. The two external objects provide an avoidance space so that the two external objects can be rotated to a state that is parallel to each other or approximately parallel to each other. This not only improves the compactness of the two external objects in the folded state, but also avoids interference between the external objects. and collision.

For example, taking two solar panel units 210 connected to each other through the hinge 100 as an example, the two solar panel units 210 can be folded to a state that is parallel to each other or nearly parallel to each other, which can improve the folding performance of the two solar panel units 210. The compactness in the folded state reduces the space size of the two solar panel units 210 in the folded state. In addition, since interference and collision between the solar panel units 210 are not easy to occur, damage to the solar panel units 210 due to mutual interference or collision can also be avoided.

It should be noted that the external objects may include various objects that need to be rotatably connected to another object through the hinge 100 , and are not limited to the solar panel unit 210 . The types of objects connected to each other through the hinge 100 are not discussed here. limited.

In practical applications, the bending angle of the second hinge part 123 relative to the first hinge part 122 can be set according to actual needs. For example, the second hinge part 123 can be bent at a relatively large angle relative to the first hinge part 122, so that the first hinge part 122 and the second hinge part 123 are close to being perpendicular to each other, As shown in the first embodiment in Figures 1 to 4. For example, the second hinge part 123 can be bent at a relatively small angle relative to the first hinge part 122, so that an obtuse angle is formed between the first hinge part 122 and the second hinge part 123, such as The second embodiment is shown in Figures 5 to 7, and the third embodiment is shown in Figures 8 to 10.
