In order to make objectives, technical solutions and advantages of the present disclosure more clearly, the technical solutions of the present disclosure will be described in a clearly and fully understandable way in connection with the specific embodiments of the present disclosure and the corresponding drawings.

The technical solutions disclosed in the various embodiments of the present disclosure are described in detail below in conjunction with the drawings.

An embodiment of the present disclosure discloses a hiding fan. Referring to <FIG>, the hiding fan includes a turntable <NUM>, a plurality of fan blades <NUM> and a synchronization mechanism <NUM>.

The synchronization mechanism <NUM> includes a rotation ring <NUM> and a plurality of connection rods <NUM>. The number of the connection rods <NUM> is equal to the number of the fan blades <NUM>. The rotation ring <NUM> is mounted on the turntable <NUM>, and the rotation ring <NUM> is configured to rotate relative to the turntable <NUM> around the central axis of the turntable <NUM>.

Each fan blade <NUM> has an installation end and a free end, the installation end has an installation portion <NUM> and a connection portion <NUM> that are spaced apart from each other, the installation portion <NUM> is mounted on the turntable <NUM> through the first rotation connection portion <NUM>; a first end of the connection rod <NUM> is mounted on the turntable <NUM> on the rotation ring <NUM> through a second rotation connection portion <NUM>, a second end of the connection rod <NUM> is mounted on the connection portion <NUM> through a third rotation connection portion <NUM>; the fan blades <NUM> is configured to rotate around the central axis of the first rotation connection portion <NUM> , and the fan blades <NUM> is configured to switch between the storage position and the unfolded position by rotating.

In the hiding fan disclosed in the present disclosure, the plurality of fan blades <NUM> are connected to each other through a synchronization mechanism <NUM>, so that each fan blade <NUM> is synchronously unfolded, or, synchronously folded and stored; the synchronization mechanism <NUM> includes a rotation ring <NUM> and a connection rod <NUM>; for hiding fans of different sizes, it is only required to change the size of the connection rod <NUM>, so that the same rotation ring <NUM> can adapt to hiding fans of different sizes, reducing the design cost and manufacturing cost of the hiding fan, and facilitating the subsequent maintenance of the hiding fan.

The structures of the first rotation connection portion <NUM>, the second rotation connection portion <NUM> and the third rotation connection portion <NUM> may be appropriately selected according to actual needs. Referring to <FIG>, in at least one embodiment of the present disclosure, the turntable <NUM> has a plurality of fan blade installation portions <NUM>, and the plurality of fan blade installation portions <NUM> are evenly spaced apart from each other along a circumferential direction of the turntable <NUM>; the first rotation connection portion <NUM> includes a first rotation shaft, and the installation portion <NUM> is mounted on the fan blade installation portion <NUM> through the first rotation shaft. The rotation ring <NUM> has a plurality of connection rod installation portions <NUM>, and the plurality of the connection rod installation portions <NUM> are evenly spaced apart from each along a circumferential direction of the rotation ring <NUM>; the second rotation connection portion <NUM> includes a second rotation shaft, and the first end of the connection rod <NUM> is mounted on the connection rod installation portions <NUM> through the second rotation shaft. The third rotation connection portion <NUM> includes a third rotation shaft, and the second end of the connection rod <NUM> is mounted on the connection portion <NUM> through the third rotation shaft. The first rotation connection portion <NUM>, the second rotation connection portion <NUM> and the third rotation connection portion <NUM> have simple structures, which is convenient for the assembly of the hiding fan.

Optionally, referring to <FIG> , <FIG> and <FIG>, along the circumferential direction of the turntable <NUM>, the plurality of connection rod installation portions <NUM> are alternately arranged with the plurality of fan blades installation portions <NUM>; the intervals between the connection rod installation portions <NUM> and the fan blade installation portions <NUM> are increased, which is convenient for the arrangement of the connection rods <NUM>, helps the fan blades <NUM> to switch smoothly between the storage position and the unfolded position, and makes the structure of the hiding fan more compact.

Referring to <FIG> again, in the embodiment of the present disclosure, along a length direction of the connection rod <NUM>, a distance between the second rotation connection portion <NUM> and the third rotation connection portion <NUM> is a first distance L1; in the case where the fan blades <NUM> are in the unfolded position, along a radial direction of the turntable <NUM>, a distance between the second rotation connection portion <NUM> and the third rotation connection portion <NUM> is a second distance L2; and the first distance L1 is greater than the second distance L2. Because the first distance L1 is greater than the second distance L2, the extending direction of the connection rod <NUM> does not coincide with the radial direction of the turntable <NUM> during the entire movement process of the connection rod <NUM>, so that a link mechanism constituted by the fan blades <NUM>, connection rods <NUM>, the rotation ring <NUM> and the turntable <NUM> moves to the dead center. A distance between the first rotation connection portion <NUM> and the third rotation connection portion <NUM> is a third distance L3, and preferably, the third distance L3 is smaller than the first distance L1, so that the structure of the hiding fan is more compact.

Optionally, the hiding fan has a position limit structure, and the position limit structure includes a unfolded position limit portion and a storage position limit portion, so that the fan blade <NUM> can only rotate between the unfolded position and the storage position, so as to prevent the rotation of the fan blades <NUM> from exceeding an expected range and improve the stability and reliability of the hiding fan. The specific structure of the position limit structure may be appropriately selected according to actual needs, for example, an arc-shaped positon limit groove is provided on the rotation ring <NUM>, and the turntable <NUM> has a protrusion block inserted into the arc-shaped positon limit groove; in the case where the fan blades <NUM> are in the unfolded position, the protruding block abuts against one end of the arc-shaped limiting slot; in the case where the fan blades <NUM> are in the storage position, the protruding block abuts against the other end of the arc-shaped limiting slot.

Referring to <FIG>, in at least one embodiment of the present disclosure, the unfolded position limit portion includes a first position limit structure <NUM> and a second position limit structure <NUM> that cooperate with each other, and the storage position limit portion includes a third position limit structure <NUM> and a fourth position limit structure <NUM> that cooperate with each other; the first position limit structure <NUM> and the third position limit structure <NUM> are arranged on the turntable <NUM>, the second position limit structure <NUM> is arranged on one selected from the group consisting of the rotation ring <NUM> and the fan blades <NUM>, the fourth position limit structure <NUM> is arranged on the other selected from the group consisting of the rotation ring <NUM> and the fan blades <NUM>. The storage position limit portion and the unfolded position limit portion are separated from each other, so as to avoid the simultaneous failure of the storage position limit portion and the unfolded position limit portion, and so that the space required for the arrangement of the storage position limit portion and the unfolded position limit portion which are arranged separately is smaller, which makes the structure of the hiding fan more compact.

Optionally, the turntable <NUM> includes an annular installation seat <NUM>, the rotation ring <NUM> is sleeved on the outer side of the annular installation seat <NUM>; the first position limit structure <NUM> is arranged on the annular installation seat <NUM>, the second position limit structure <NUM> is arranged on the rotation ring <NUM>; the first position limit structure <NUM> is a first position limit protrusion protruding toward the rotation ring <NUM> along a radial direction of the turntable <NUM>, and the second position limit structure <NUM> is a second position limit protrusion protruding toward the annular installation seat <NUM> along the radial direction of the turntable <NUM>; in the case that the fan blades <NUM> are in the unfolded position, the first position limit protrusion and the second position limit protrusion abut against each other, so as to prevent the fan blades <NUM> from continuing to rotate toward the direction which makes the fan blades <NUM> be unfolded. The fourth position limit structures <NUM> are respectively arranged on the fan blades <NUM>, the third position limit structure <NUM> is a third position limitation protrusion protruding toward the fan blades <NUM> along a thickness direction of the turntable <NUM>, and the fourth position limit structure <NUM> a fourth position limitation protrusion protruding toward the turntable <NUM> along a thickness direction of the turntable <NUM>. In the case where the fan blades <NUM> are in the storage position, the third position limitation protrusion and the fourth position limitation protrusion abut against each other, so as to prevent the fan blades <NUM> from continuing to rotate toward the direction which makes the fan blades <NUM> be folded and stored. The above-mentioned unfolded position limit portion and storage position limit portion are simple in structure, require less space for arrangement, and facilitate the arrangement of the position limit structure.

Optionally, the hiding fan further includes an elastic reset member (not shown in the figures), the elastic reset member includes a first installation portion and a second installation portion; the first installation portion is fixed relative to the turntable <NUM>, and the second installation portion is fixed relative to the fan blades <NUM>. The elastic reset member applies an elastic force to the fan blades <NUM> to keep the fan blades <NUM> in the storage position; once the fan blades <NUM> stop rotating, they will return to the storage position under the action of the elastic force of the elastic reset member. Specifically, when the hiding fan is started, the fan blade <NUM> starts to rotate under the driving of the driver motor <NUM>, and the centrifugal force of the fan blades <NUM> overcomes the elastic force of the elastic reset member, so that the fan blades <NUM> automatically stretch to the unfolded position; when the hiding fan is closed, the fan blades <NUM> stop rotating, the centrifugal force disappears, and the fan blades <NUM> are reset to the storage position under the action of the elastic force of the elastic reset member.

The embodiment of the present disclosure also discloses a fan lamp, referring to <FIG> , the fan lamp includes a lamp assembly <NUM>, a motor assembly <NUM> and the hiding fan described above; the lamp assembly <NUM> is arranged on the side of the turntable <NUM> away from the fan blades <NUM>, the motor assembly <NUM> is arranged on the side of the turntable <NUM> facing the fan blades <NUM>, and the rotation ring <NUM> is sleeved on the outer periphery of the motor assembly <NUM>; the fan lamp has the same advantages as the above-mentioned hiding fan, and the same advantages are not repeated here.

Optionally, the fan lamp includes a driver <NUM>; the driver <NUM> is electrically connected to the motor assembly <NUM> through a first electrical connector, and the driver <NUM> is electrically connected to the lamp assembly <NUM> through a second electrical connector. The motor assembly <NUM> and the lamp assembly <NUM> for driving the fan blade <NUM> may be electrically connected with the same driver <NUM>, so that the hiding fan and the lamp assembly <NUM> cab be driven by the same one driver <NUM>; compared with the way in which the hiding fan and the lamp assembly <NUM> are respectively driven by their respective drivers, the number of parts and components of the fan lamp disclosed in the embodiments of the present disclosure is reduced, so the fan lamp occupies a smaller space and, meanwhile, facilitates the transportation of the fan lamp.

In the embodiment of the present disclosure, the motor assembly <NUM> includes a motor cover <NUM> and a driver motor <NUM> mounted in the motor cover <NUM>; the motor cover <NUM> can protect the driver motor <NUM> and make the appearance of the fan lamp more beautiful. The driver motor <NUM> may be connected to the turntable <NUM> by transmission in any appropriate manner; in the embodiments of the present disclosure, the driver motor <NUM> is fixedly mounted on the annular installation seat <NUM>, and the annular installation seat <NUM> has a central opening <NUM> in the middle to reduce the weight of the turntable 100and avoid interference between the turntable <NUM> and the driver motor <NUM>.

The specific structure of the lamp assembly <NUM> may be appropriately selected according to the usage requirements. Optionally, the lamp assembly <NUM> includes a lamp plate <NUM>, a light source module <NUM> and a lamp shade <NUM>.
