In the embodiment of the present application, the holder body is used for supporting the first body and the second body. The structure of the seat body is not limited. For example, the seat body may have a column structure or a tube structure.

In the embodiments of the present application, the first body is used to fix other structures supported by the support device. Other structures supported by the supporting device can be a lamp assembly and also can be a display assembly. The structure of the first body is not limited. For example, the first body may have a bar-type structure or a block-type structure.

Here, the implementation manner of the first body hinged with the first portion of the seat body is not limited. For example, the first part of the seat body is provided with a through hole, the first body is provided with a through hole at a position corresponding to the through hole of the seat body, and the first body is hinged to the first part of the seat body by penetrating through the through hole of the seat body and the through hole of the first body through a cylindrical structure.

In the embodiment of the present application, the structure of the second body is not limited. For example, the second body may have a strip-type structure or a block-type structure.

Here, the implementation manner of the second body hinged with the second portion of the seat body is not limited. For example, the second part of the seat body is provided with a through hole, the second body is provided with a through hole at a position corresponding to the through hole of the seat body, and the second body is hinged to the second part of the seat body by penetrating through the through hole of the seat body and the through hole of the second body through a cylindrical structure.

In the embodiment of the present application, the structure of the slider is not limited. For example, the slider may have a bar-type structure or a block-type structure.

In the embodiment of the present application, the structure of the first limiting structure is not limited as long as the first surface of the sliding member abuts against the second surface of the first body through the first limiting structure, and the sliding member moves along the second surface relative to the first body during the rotation of the first body. For example, the first limit structure may include: the first slide way is arranged on the sliding piece; the sliding part is sleeved outside the first body through the first slide way, the first surface of the sliding part is abutted to the second surface of the first body through the first slide way, and the sliding part moves along the second surface relative to the first body along with the rotation of the first body in the process. Here, the first body may have a bar-type structure, the second surface may be located in a longitudinal direction of the first body, and the slider moves along the second surface in the longitudinal direction of the first body as the first body rotates. Here, the first surface may be a surface of the first body abutting against the first runner, and the second surface may be an inner wall surface of the first runner.

In the embodiment of the present application, the structure of the second position-limiting structure is not limited as long as the third surface of the slider abuts against the fourth surface of the second body through the second position-limiting structure, and the second body moves along the third surface relative to the slider along with the rotation of the first body. For example, the second limiting structure may include: the second slide way is arranged on the second body; the sliding piece is provided with a protruding structure matched with the second slide way, the second slide way is sleeved outside the protruding structure, the fourth surface of the second body is abutted against the third surface of the sliding piece through the second slide way sleeved outside the protruding structure, and the second body moves along with the third surface of the sliding piece along with the sliding piece in the rotating process of the first body. Here, when the slider is provided with both the first slide and the protruding structure, the slider may be a bar-type structure, the first slide may be disposed along a length direction of the slider, and the protruding structure may be disposed along a width direction of the slider. Here, the third surface may be a surface of the projection structure abutting against the second runner, and the fourth surface may be an inner wall surface of the second runner.

In this embodiment of the application, when a rotation angle of the first body relative to the seat needs to be adjusted, the first body is rotated by force to rotate the first body relative to the seat, at this time, the sliding member and the second body both rotate relative to the seat along with the rotation of the first body, the sliding member moves along the second surface relative to the first body during the rotation, and the second body moves along the third surface relative to the sliding member during the rotation; when the first body rotates to a proper position relative to the seat body, the force for rotating the first body is cancelled, and at the moment, the abutting friction force between the first surface and the second surface can maintain the rotation angle of the first body relative to the seat body; thereby securely holding the first body in the proper rotational position.

In some optional implementation manners of the embodiment of the present application, the first limiting structure may include: the limiting accommodating cavity is arranged on the first body; the second surface is positioned in the limiting accommodating cavity; the sliding part is arranged in the limiting accommodating cavity, and the first surface of the sliding part is abutted against the second surface through the limiting accommodating cavity; when the first body rotates relative to the seat body, the sliding part rotates relative to the seat body along with the rotation of the first body in the limiting accommodating cavity.

In this implementation manner, the limiting accommodating cavity may be disposed in the first body or on the surface of the first body.

For example, the position-limiting accommodating cavity is disposed in the first body, and the first body may further include: the opening is communicated with the limiting accommodating cavity; the slider is exposable through the opening; the second limit structure may include: the limiting groove is arranged on the sliding piece and corresponds to the position of the opening; the notch of the limiting groove is positioned on a fifth surface of the sliding part which can be exposed through the opening, and the opposite two side surfaces of the limiting groove form the third surface; the opposite two side surfaces of at least part of the structure of the second body form the fourth surface, the at least part of the structure of the second body is positioned in the limit groove through the opening, and the opposite two side surfaces of the at least part of the structure of the second body are respectively abutted with the opposite two side surfaces of the limit groove one by one; when the first body rotates relative to the seat body, the second body rotates relative to the seat body along with the rotation of the first body, and the second body moves along two opposite side surfaces of the limiting groove relative to the sliding piece in the rotating process.

Here, the structure of the first body is not limited. For example, the first body is composed of a structural member, and in this case, the second surface may be an inner wall surface of the position-limiting accommodating cavity. For another example, the first body is composed of a plurality of structural members, and in this case, the second surface may be a surface of one of the structural members.

Here, the second body may be entirely located in the limiting groove, and at this time, opposite side surfaces of the second body respectively abut against opposite side surfaces of the limiting groove one by one. Of course, only part of the second body may be located in the limiting groove, and at this time, two opposite side surfaces of the part of the second body are respectively abutted to two opposite side surfaces of the limiting groove one by one.

In an example, as shown in fig. 1 to 3, the first body may further include: a first connecting member 210 and a friction member 220; the position-limiting accommodating cavity 211 is arranged in the first connecting piece 210, and the opening 212 is arranged on the first connecting piece 210; the friction member 220 is fixed in the position-limiting accommodation cavity 211 and hinged with the first part of the seat body at the opening 212; the surface of the friction member 220 forms the second surface 102; the opposite two side surfaces of the second body form the fourth surface 104, the second body is located in the limiting groove 410 through the opening 212, and the opposite two side surfaces of the second body are respectively abutted to the opposite two side surfaces of the limiting groove 410 one by one; the second portion of the housing is hinged to the second body through the opening 212 in the retaining groove 410. Here, the limiting groove 410 is located on the fifth surface 105 where the slider 400 can be exposed through the opening 212; the third surface 103 is formed on two opposite sides of the limiting groove 410.

In an example, in a process that the first connecting element 210 drives the friction element 220 to rotate in a first direction relative to the seat under an external force, when the first connecting element 210 rotates to a first rotation position, the sliding element 400 moves to a first movement position along a surface of the friction element 220, and the second body moves to form a first gap H with the friction element 220 along two opposite side surfaces of the limiting groove 410, as shown in fig. 4 and 5. When the first connecting member 210 rotates from the first rotational position to the second rotational limit position, the sliding member 400 moves along the surface of the friction member 220 in the second direction, the second body moves along the opposite sides of the limiting groove 410 toward the notch close to the limiting groove 410, and the gap between the second body and the friction member 220 gradually decreases; when the first connecting member 210 rotates to the second rotation limit position, the sliding member 400 moves along the surface of the friction member 220 to a second movement limit position in a second direction, and the second body moves along the opposite side surfaces of the limiting groove 410 to the direction close to the notch of the limiting groove 410 to abut against the friction member 220; as shown in fig. 6 and 7, at this time, the first connecting member 210 cannot be rotated any more since the second body abuts against the friction member 220. In the process that the first connecting part 210 drives the friction part 220 to rotate in the third direction relative to the seat body under the action of external force; when the first connecting member 210 rotates from the first rotational position to the third rotational limit position, the slider 400 moves along the surface of the friction member 220 in the fourth direction, the second body moves along the opposite sides of the limiting groove 410 toward the notch close to the limiting groove 410, and the gap between the second body and the friction member 220 gradually decreases; when the first connecting member 210 rotates to the third rotation limit position, the sliding member 400 moves along the surface of the friction member 220 in the fourth direction to the third movement limit position, and the second body moves along the opposite sides of the limiting groove 410 toward the notch close to the limiting groove 410 to abut against the friction member 220; as shown in fig. 8 and 9, at this time, the first connecting member 210 cannot be rotated any more since the second body abuts against the friction member 220.

Here, the third direction is opposite to the first direction. For example, the first direction is clockwise rotation and the third direction is counterclockwise rotation. As an example, the first direction is the a direction shown in fig. 5, and the third direction is the B direction shown in fig. 5.

Here, the fourth direction is opposite to the second direction. For example, the second direction is a direction from the first end of the position-limiting accommodation cavity 211 to the second end of the position-limiting accommodation cavity 211, and the fourth direction is a direction from the second end of the position-limiting accommodation cavity 211 to the first end of the position-limiting accommodation cavity 211.

Here, it should be understood by those skilled in the art that the larger the first gap H, the larger the angle through which the first link 210 rotates to the second rotation limit position and the third rotation limit position, and those skilled in the art can set the size of the first gap H according to actual needs.

Here, a person skilled in the art can set the position relationship between the first connecting element 210 and the seat body when the first connecting element 210 rotates to the first rotating position according to actual needs. As an example, as shown in fig. 4 and 5, when the first connecting element 210 rotates to the first rotating position, the first connecting element 210 is substantially perpendicular to the seat body, a connecting line is formed between a hinge point of the friction element 220 and the seat body and a hinge point of the second body and the seat body, and the connecting line is substantially perpendicular to the sliding direction of the sliding element 400; at this time, when the first connecting piece 210 rotates to the second rotation limit position, a second included angle is formed between the first connecting piece 210 and the seat body; when the first connecting member 210 rotates to a third rotation limit position, a third included angle is formed between the first connecting member 210 and the seat body, and the third included angle is equal to the second included angle.

In one example, the structure of the first connector 210 is not limited. For example, the first connection member 210 may have a bar-type structure; here, the space-limiting accommodating cavity 211 may be a bar-shaped cavity. For another example, as shown in fig. 2 and 3, the first connecting member 210 has a column-shaped structure; here, the space-limiting accommodating cavity 211 may be a bar-shaped cavity. Of course, the limiting accommodating cavity 211 may also be a column-shaped cavity or a cube-shaped cavity.

In an example, the structure of the friction member 220 is not limited as long as the friction member 220 can be placed in the position-limiting accommodation cavity 211. For example, the friction member 220 may have a bar-type structure or a plate-type structure. Here, the implementation manner of the friction member 220 hinged with the first portion of the housing is not limited. For example, the friction member 220 can be directly hinged to the first portion of the housing. For another example, as shown in fig. 3 and 10, and 11, the first body may include: a fourth link 230 and a connecting stud 240; the base body is provided with a first through hole 201, a first end of the fourth connecting piece 230 is provided with a second through hole 202, and a second end of the fourth connecting piece 230 is provided with a first threaded hole 203; the cylindrical member 250 passes through the first through hole 201 and the second through hole 202 to be connected with the nut 205, so that the seat body is hinged with the fourth connecting member 230; the friction piece 220 is provided with a third through hole 204, and the friction piece 220 is fixedly connected with the fourth connecting piece 230 by connecting a connecting stud 240 with the first threaded hole 203 through the third through hole 204; thereby achieving the hinge connection of the friction member 220 with the first portion of the housing. Here, the first end of the fourth connector 230 may be provided with two second through holes 202, and the first portion of the holder body may be located between walls forming the two second through holes 202; in order to further increase the friction force of the first connection element 210 rotating relative to the base, the support device may further include two elastic spacers 206, one of the two elastic spacers 206 is disposed between the head of the cylindrical element 250 and the fourth connection element 230 and abuts against the head of the cylindrical element 250 and the fourth connection element 230, and the other of the two elastic spacers 206 is disposed between the nut 205 and the fourth connection element 230 and abuts against the nut 205 and the fourth connection element 230.
