The present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the description of the embodiments of the present application, it should be noted that, unless otherwise specified and limited, the term "connected" should be interpreted broadly, for example, as an electrical connection, a communication between two elements, a direct connection, or an indirect connection via an intermediate, and the specific meaning of the terms may be understood by those skilled in the art according to specific situations.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The connecting device according to the embodiment of the present application will be described in detail below with reference to fig. 1 to 5.

The connecting device includes: a first structural member 110, a second structural member 120, and a connector 130. The link 130 has a rotating portion 131 and a sliding portion 132; the rotating part 131 and the sliding part 132 are fixedly connected; the rotating portion 131 is rotatably connected to the first structure 110, the sliding portion 132 is slidably connected to the second structure 120, and the first structure 110 is rotatable with respect to the second structure 120 through the rotating portion 131; the first structure member 110 is slidable with respect to the second structure member 120 via the sliding portion 132; the state between the first structural member 110 and the second structural member 120 can be changed, and the adaptability of the connecting device is greatly improved.

In the embodiment of the present application, the structure of the first structural member 110 is not limited. For example, the first structural member 110 may be a plate-shaped structure.

In the embodiment of the present application, the structure of the second structural member 120 is not limited. For example, the second structural member 120 may be a plate-like structure.

In the embodiment of the present application, the fixed connection between the rotating portion 131 and the sliding portion 132 is not limited. For example, the rotating portion 131 and the sliding portion 132 are different portions of the same structure. For another example, the rotating portion 131 and the sliding portion 132 have different structures, and in this case, the rotating portion 131 and the sliding portion 132 may be connected by welding, gluing, or the like.

The rotatable portion 131 is rotatably connected to the first structure 110 in an implementation manner without limitation. For example, the rotating portion 131 and the first structural member 110 may be rotatably connected by a rotating shaft; here, at least one of the rotating portion 131 and the first structural member 110 is rotatably connected to the rotating shaft.

Here, the implementation manner of slidably connecting the sliding portion 132 and the second structure 120 is not limited. For example, the second structure member 120 is provided with a cylindrical body, the sliding portion 132 is provided with a cylindrical sliding groove, and the sliding portion 132 is slidably connected with respect to the second structure member 120 by being sleeved outside the cylindrical body through the cylindrical sliding groove; here, the columnar slide groove is slidable with respect to the columnar body.

Here, the first structure 110 is rotatable with respect to the second structure 120 by the rotating portion 131, and the rotating portion 131 is used to change a rotation angle between the first structure 110 and the second structure 120 so as to make a multi-angle state between the first structure 110 and the second structure 120.

Here, the first structure 110 is slidable with respect to the second structure 120 by the sliding portion 132, and the sliding portion 132 is used to change the distance between the first structure 110 and the second structure 120 so as to have a state of a plurality of distances between the first structure 110 and the second structure 120.

In some optional implementations of the embodiments of the present application, with the sliding portion 132 in the first sliding position, the first structural member 110 can rotate within the first angle range through the rotating portion 131, and the first structural member 110 and the second structural member 120 have a first distance therebetween; when the sliding portion 132 slides from the first sliding position to the second sliding position, the first structure 110 is rotatable within a second angular range by the rotating portion 131, and the distance between the first structure 110 and the second structure 120 increases from the first distance to a second distance; wherein angles in the second angular range are greater than angles in the first angular range.

In this implementation, the angles in the second angular range are greater than the angles in the first angular range, and the value of the second distance is greater than the value of the first distance; so that the rotation angle between the first and second structural members 110 and 120 can be increased by increasing the distance between the first and second structural members 110 and 120 in the case where the space between the first and second structural members 110 and 120 is limited; meanwhile, with the sliding portion 132 in the first sliding position, the first structure 110 can rotate within the first angular range through the rotating portion 131, so as to reduce an installation space for the first structure 110 and the second structure 120 to rotate within the first angular range.

In this embodiment, the embodiment in which the sliding portion 132 is in the first sliding position is not limited. For example, the sliding part 132 is connected to the second structural member 120 through the elastic member 140, and the elastic member 140 maintains the sliding part 132 stably at the first sliding position; when the external force applied to the sliding portion 132 is greater than the elastic force of the elastic member 140, the sliding portion 132 slides from the first sliding position to the second sliding position.

Here, the structure of the elastic member 140 is not limited. For example, the elastic member 140 may be a helical tension spring.

Here, the value of the first angle range is not limited. For example, the first angle range is 0 to 135 degrees.

Here, the value of the second angle range is not limited. For example, the first angle range is 0 to 135 degrees, and the second angle range is 135 to 180 degrees; it is noted that, among other things, the first angular range includes 135 degrees.

In some optional implementations of the embodiment of the present application, during the rotation of the first structural member 110 from the folded state to the unfolded state in the first direction by the rotating portion 131 relative to the second structural member 120, the first structural member 110 rotates from the first rotation position to the second rotation position by the rotating portion 131 relative to the second structural member 120, the first structural member 110 is in the first sliding position relative to the second structural member 120 by the sliding portion 132, and the first structural member 110 and the second structural member 120 have a first distance therebetween; the first structure member 110 is rotated from the second rotation position to a third rotation position relative to the second structure member 120 by the rotating portion 131, the first structure member 110 is slid from the first sliding position to a second sliding position in a second direction relative to the second structure member 120 by the sliding portion 132, and a distance between the first structure member 110 and the second structure member 120 is increased from the first distance to a second distance.

In this implementation, the angle between the first structure 110 and the second structure 120 in the first rotational position is not limited. For example, as shown in fig. 1, the included angle between the first structural member 110 and the second structural member 120 in the first rotational position is 0 degrees. The angle between the first structure 110 and the second structure 120 in the second rotational position is not limited. For example, as shown in fig. 2, the angle between the first structural member 110 and the second structural member 120 in the second rotational position is 135 degrees. The angle between the first structure 110 and the second structure 120 in the third rotational position is not limited. For example, as shown in fig. 3, the angle between the first structural member 110 and the second structural member 120 in the third rotational position is 180 degrees.

In this implementation, the implementation that the sliding portion 132 is at the first sliding position has been described above, and is not described herein again.

In the present embodiment, the first direction is not limited as long as the first structural member 110 is rotated from the folded state to the unfolded state with respect to the second structural member 120 by the rotating portion 131. For example, the first direction may be clockwise or counterclockwise.

The second direction is a direction that satisfies a perpendicular condition with respect to the first surface of the second structural member 120, that is, the second direction is a direction perpendicular to the first surface of the second structural member 120; alternatively, the second direction is a direction substantially perpendicular to the first surface of the second structure 120. Here, the first surface may be a top surface or a bottom surface of the second structural member 120.

In some alternative implementations of the embodiments of the present application, as shown in fig. 1 to 5, the first structural member 110 has a rotating shaft portion 111; two ends of the rotating shaft part 111 are respectively provided with an abutting part 112; the second structural member 120 has two protrusions 121 and two slide ways 122 arranged at intervals; the slide way 122 is positioned between the two protrusions 121; the two protrusions 121 are respectively in contact with the two abutting portions 112; the rotating portion 131 is sleeved outside the rotating shaft portion 111, the rotating portion 131 can rotate relative to the rotating shaft portion 111, the sliding portion 132 is inserted into the slideway 122, and the sliding portion 132 can move relative to the slideway 122; the connection device may further include: the elastic element 140, the elastic element 140 is at least partially disposed in the slideway 122, and the elastic element 140 is connected to the sliding part 132 for pulling the connecting element 130 to make the abutting part 112 contact with the protrusion 121.

In this embodiment, the structure of the rotating shaft 111 is not limited, and the rotating part 131 can rotate relative to the rotating shaft 111 as long as the rotating part 131 is sleeved outside the rotating shaft 111. For example, as shown in fig. 4, the rotating shaft portion 111 has a cylindrical structure, and the rotating portion 131 has a cylindrical structure.

In the present embodiment, the structure of the abutting portion 112 is not limited. For example, the abutment 112 is a cam structure.

In this embodiment, the structure of the protrusion 121 is not limited as long as the two protrusions 121 respectively contact with the two abutting portions 112. For example, as shown in FIG. 4, the protrusions 121 are boss structures.

In this implementation, the structure of the chute 122 is not limited, as long as the sliding portion 132 is inserted into the chute 122, and the sliding portion 132 is movable relative to the chute 122. For example, as shown in fig. 4, the slide 122 has a rectangular cross section, and the sliding portion 132 has a rectangular parallelepiped structure.

In this implementation, the elastic member 140 has already been described above, and is not described herein again. As an example, as shown in fig. 4 and 5, the second structural member 120 may further include: a first slot 123 and a second slot 124; the first slot 123 is disposed on a first side wall forming the slideway 122, and the first slot 123 is communicated with the slideway 122; a second slot 124 is disposed in a second sidewall forming the chute 122, the second slot 124 being in communication with the chute 122; wherein the second sidewall and the first sidewall are disposed opposite to each other; the elastic member 140 may have a plate-shaped structure, and the elastic member 140 may include: a first end 141, a second end 142, and a connecting portion 143; the first end portion 141 is inserted into the first slot 123; the second end 142 is inserted into the second slot 124; the connecting portion 143 is connected to the first end portion 141 and the second end portion 142, and the connecting portion 143 is inserted into the through slot 1321; so that the disposition space of the elastic member 140 is reduced.

In the present implementation, as shown in fig. 4, the abutment portion 112 may include a first abutment surface 1121 and a second abutment surface 1122, the first abutment surface 1121 and the second abutment surface 1122 being connected; the first abutment surface 1121 is a third distance from the rotational axis; a fourth distance is provided between a middle portion of the second abutment surface 1122 and the rotational axis, which is an axis of relative rotation between the first structure 110 and the second structure 120, and the third distance is smaller than the fourth distance; wherein the first abutting surface 1121 is a partial cylindrical surface, the second abutting surface 1122 is an inclined surface, and the protrusion 121 is contacted by the first abutting surface 1121 with the same distance from the rotation axis, so that the distance between the first structural member 110 and the second structural member 120 is constant when the first structural member 110 rotates relative to the second structural member 120; the protrusion 121 is in contact with the second abutment surface 1122 having a different distance from the rotation axis, so that when the first structure 110 is rotated relative to the second structure 120, the distance between the first structure 110 and the second structure 120 can be increased, and the rotation angle between the first structure and the second structure can be increased.

Here, the first abutment surface 1121 and the second abutment surface 1122 are smoothly connected, the protrusion 121 is in contact with the first abutment surface 1121, the sliding portion 132 is located at a first sliding position, and the first structural member 110 and the second structural member 120 have a first distance therebetween, during the rotation of the first structural member 110 relative to the second structural member 120 from the folded state to the unfolded state in the first direction; the larger the included angle between the first structural member 110 and the second structural member 120, the larger the protrusion 121 contacts the second abutment surface 1122, and the sliding portion 132 slides from the first sliding position to the second sliding position; the distance between the first structure 110 and the second structure 120 is from the greater the first distance to a second distance.

In this implementation, when the first structure 110 is rotated relative to the second structure 120 within a first angular range by the rotating portion 131, the first abutting surface 1121 abuts against the protrusion 121, the sliding portion 132 is located at a first sliding position relative to the slideway 122, and a first distance is provided between the first structure 110 and the second structure 120; when the first structure 110 is rotated relative to the second structure 120 through the rotating portion 131 within a second angle range, the second abutment surface 1122 abuts against the protrusion 121, the sliding portion 132 slides relative to the slide rail 122 between the first sliding position and a second sliding position, and a distance between the first structure 110 and the second structure 120 is greater than the first distance; wherein angles within the first range of angles are less than angles within the second range of angles.

The first angle range and the second angle range have been described above, and are not described in detail herein.
