Detailed Description

As an important component in movable building skins, the way in which they are driven and the way in which they are implemented are of great significance for the construction and implementation of movable building skins.

A drive arrangement for providing a driving force in a movable building skin is presented in the present example, in the present example named stator assembly 100. The stator assembly 100 has a substantially cylindrical structure and can be matched with a display part 200 (or a skin unit or a display unit or the like) in a movable building skin, and the display part 200 can rotate in a controlled manner by providing driving force through the stator assembly 100, so that different display information and contents can be provided. When the movable building representation is arranged in a large area, different display parts 200 are rotated to their own corresponding angles, orientations, etc. by their corresponding stator assemblies 100, so that a designed content, such as various patterns, characters, can be formed by combining the plurality of display parts 200, and a content, such as dynamic pictures, can be realized by continuously controlling, or various static objects with changed brightness can be displayed.

The display portion 200 may be in various structures in the art, and is not particularly limited in this application. The demonstration portion 200 may be mated with the stator assembly 100 in the present example of application in various forms. Generally, the demonstration part 200 has a cylindrical hole so that the cylindrical stator assembly 100 is inserted into the hole to be matched with the hole, and the cylindrical hole has a driven part which is in transmission fit with a driving part (hereinafter, referred to as a driving part 1031) of the stator assembly 100. Thus, when the stator assembly 100 is fixed on a building wall or other vertical surface, the stator assembly 100 can drive the display part 200 to rotate, so as to construct different displays.

As an example, fig. 1 illustrates a fitting structure of a stator assembly 100 and a demonstration portion 200 in an example of the present application; wherein the vertical dashed lines indicate the center line of rotation of the display portion 200 driven for gyratory motion by the stator assembly 100, and the double solid arrow lines indicate the direction of rotation. As shown in FIG. 1, the display portion 200 is generally a triangular prism structure and has primarily three panels. The three panels can be distributed with different patterns or shapes or characters or color blocks with different light and shade according to design requirements.

The cylindrical stator assembly 100 in the present example will be described in detail below with reference to the drawings.

The stator assembly 100 is configured as shown in fig. 2, and the exemplary stator assembly 100 is generally cylindrical or columnar in shape. The manner and configuration of splicing the two stator assemblies 100 is shown in fig. 3, i.e., the two stator assemblies 100 are connected in an axial direction or defined as a first predetermined direction (i.e., the vertical dashed line in fig. 1). Also, the two stator assemblies 100 are connected end to end.

Referring to fig. 2 to 11, the stator assembly 100 includes a housing 101, a motor, and a transmission mechanism. The motor and the transmission are disposed inside the housing 101. The motor is not exposed, and the transmission mechanism has a driving part 1031, a gear in the illustrated structure of the present example, exposed outside the housing 101. As such, when the stator assembly 100 is mounted in the hole of the decoration part, the driving part 1031 can cooperate with the display part 200 to rotate the display part 200 by the driving part 1031.

Casing 101

As shown in fig. 2, the casing 101 has a column structure as a whole, and extends along a first predetermined direction, so that it has two ends in the first predetermined direction, which are respectively denoted as an a end 902 and a B end 901 for convenience of description. Fig. 4, 5, and 6 are enlarged views of a portion of the a end 902 and the B end 901.

The housing 101 is embodied as an internal housing cavity, and the housing cavity is defined by a first side shell 1011 and a second side shell 1012 that form the housing 101, see fig. 7 and 8. The first side housing 1011 and the second side housing 1012 are cooperatively coupled to each other. The connection may be a fixed connection, such as an interference fit or a weld or adhesive.

In other examples, the first side housing 1011 and the second side housing 1012 may be selectively removably attached to facilitate maintenance of the stator assembly 100, while also improving flexibility and reducing costs. For example, the contact portions of the two side cases are connected by means of magnetic attraction. This means that magnets, materials capable of magnetic attraction with the magnets such as iron pieces, can be embedded in the side casing.

Or, in other examples, the first side housing 1011 has the latch 10111 located in the housing cavity, the second side housing 1012 has the insertion hole 10121 located in the housing cavity, and the latch 10111 is in plug-fit connection with the insertion hole 10121. In these examples, the plug 10111 and the socket 10121 are inserted along a second predetermined direction, such as a radial direction of the cylindrical housing 101. Further, the first side housing 1011 and the second side housing 1012 may be provided with a pin and hole structure at the ends thereof, respectively, for fitting. That is, two ends of the first side shell 1011 are respectively provided with a pin hole, and two ends of the second side shell 1012 are respectively correspondingly provided with a pin hole; so that the first side housing 1011 and the second side housing 1012 can be connected by a plug-in fit when they are connected by a fit.

Further, the two side casings can limit and fix the side casings from the outer surfaces. For example, the outer side of the housing has a flange mounting position 700 and a bearing mounting position 701, and thus the flange mounting position 700 is provided with a flange, and the bearing mounting position 701 is provided with a bearing, and the flange and the bearing are provided at both ends of the housing, respectively. The bearing may be connected to the first side case and the second side case by means of, for example, an interference fit, so that the two side cases are firmly combined together and thus the motor and the gear inside thereof are stably mounted.

Wherein the flange is located on the inner side in the axial direction of the housing, and the bearing is located on the outer side in the axial direction of the housing. The flanges may prevent the bearings at both ends of the housing from approaching. And further, the bearings at the two ends of the shell move towards the direction far away from each other, so that the outer rotor component matched with the stator component can be restrained and limited. In this manner, when the stator assembly and the outer rotor assembly cooperate to constitute the movable building skin, the bearing is restricted in both directions of the thickness or the axial direction thereof, and therefore, the bearing can maintain the fixation of the relative position in the axial direction with the housing, and therefore, the outer rotor can be stably rotated.

In addition to the above connection manner, the two side cases in the housing 101 in some examples may be connected (may be detachably connected) by:

the first side case 1011 is provided with a first connection portion at a first end portion. The second side case 1012 has a second connecting portion at a second end portion. And, the first connection portion and the second connection portion are each independently located at both ends of the case 101; for example, the first connection is at the a-end 902 of the housing 101, while the second connection is at the B-end 901 of the housing 101; and vice versa. Illustratively, in the housing 101, the first connection portion of the first side case 1011 and the second connection portion of the second side case 1012 are detachably connected along a second preset direction, and the first preset direction and the second preset direction are criss-cross. Wherein the first connecting portion is provided with a threaded hole and the second connecting portion is provided with an external thread, and therefore when the two are in a manner such as threaded connection, the connecting direction of the two is along a first preset direction. Or the first connecting part is provided with a protruding structure along a first preset direction, the second connecting part is provided with a recess along the first preset direction, and the protruding structure is spliced with the recess. In such an example, the connection direction of the first connection portion and the second connection portion is along a first preset direction. Therefore, the connecting direction of the first connecting portion and the second connecting portion refers to a moving direction in which they gradually approach each other when they are connected. In the present example, the first connection portion of the first side case 1011 and the second connection portion of the second side case 1012 are connected in a second predetermined direction.

As an alternative example, the first connection portion and the second connection portion are connected in a male-female fit manner. For example, the first connection portion is a dovetail slot 920 and the second connection portion is a dovetail block 910 that mates with the dovetail slot 920. And, along a second predetermined direction, the dovetail block 910 approaches and is inserted into the dovetail slot 920. It should be noted that the dovetail slot 920 and the dovetail block 910 may be located on the same side housing (the first side housing 1011 or the second side housing 1012); alternatively, the dovetail slot 920 and the dovetail block 910 may alternatively be located on the first and second side shells 1011, 1012, respectively. For example, in the illustrated structure of the present example, the dovetail groove 920 and the dovetail block 910 are respectively located at the fore and aft ends of the first side housing 1011.

Further, the surface of the dovetail block 910 may be configured with protrusions 911, and correspondingly, the inner surface of the dovetail slot 920 may be configured with grooves 921 matching the protrusions. The fitting mechanism of the protrusion 911 and the groove 921 therein is mainly used for connection between the housings 101 of two adjacent stator assemblies 100. The protrusion 911 and the groove 921 are inserted in a first predetermined direction. The shape of the protrusion 911 and the shape of the groove 921 matching with the protrusion can be designed according to the requirement, and are not particularly limited. Illustratively, the protrusions 911 may refer to a cylindrical or prismatic shape or a spherical or other profiled structure.

Further, in order to facilitate detachment and separation of the two side cases, the protrusion 911 may be optionally configured to be retractable in the first preset direction. For example, the surface of the dovetail block 910 has a sliding groove 913, an elastic member is installed in the sliding groove 913, and the protrusion 911 is installed in the sliding groove 913 by the sliding member 912 and pressed by the elastic member. Thus, when not operated, the elastic member is in an original length or pressed state, so that the projection 911 is restricted from being retracted into the groove, and therefore, the projection 911 is partially projected out of the sliding groove 913 and inserted into the groove 921. At this time, the adjacent two housings 101 may be connected by the fitting of the groove 921 and the projection 911. When it is desired to remove the two, the protrusion 911 may be pushed to compress the resilient member, so that the resilient member shortens, and the protrusion 911 disengages from the groove 921 and enters partially or completely into the sliding groove 913. The other connection between the two housings 101 can then be removed.

As an alternative similar to the above-mentioned combination of the groove 921 and the protrusion 911 to achieve the connection scheme of the housing 101 in different stator assemblies 100, in other examples, the first end of the first side shell 1011 may also have a T-shaped protrusion 922, while the second end of the second side shell 1012 also has a T-shaped groove 914. Moreover, the T-shaped protrusion 922 is inserted into the T-shaped groove 914 along a second predetermined direction. In this way, when the housings 101 in different stator assemblies 100 are connected, the T-shaped protrusion 922 and the T-shaped groove 914 can be inserted and matched, so that the connection firmness is also improved.

Electric machine

The motor is a power source of the stator assembly 100, which is left in the housing cavity. The motor is mounted in the housing 101 with its output shaft arranged along the axial/first preset direction of the housing 101. In other examples, the output shaft of the motor may also be arranged in the radial direction of the housing 101, if this is indeed required.

The motor may be fixed in the housing cavity of the housing 101, or may be detachably disposed in the housing cavity. In the illustrated structure of the present example, the motor is detachably disposed in the housing cavity of the housing 101. For example, two side cases have annular ribs therein, and the two side cases are engaged, and the two annular ribs respectively define the upper and lower end surfaces of the motor, and the motor is firmly and stably confined in the housing cavity of the housing 101 by the side walls. The motor is provided by conventional techniques in the art and will not be described in detail in this application.

The power supply of the motor may be provided inside the housing 101 so as to be integrated into the stator assembly 100. Alternatively, the power supply of the motor is additionally configured independently of the stator assembly 100. Thus, in such an example, the cable of the motor is provided to the housing 101. When the movable building skin needs to be built, the movable building skin is electrically connected with the cable through an additionally provided power adapter or an electric wire. Further, the cable can also be designed to take into account the signal transmission function (the cable has both power supply and signal transmission). As such, the controller is connected with the cable to control the output of the motor.

The controller may be any type of electronic component or collection of components capable of certain data storage and processing. For example, the controller may illustratively be selected from a Central Processing Unit (CPU), a Micro Control Unit (MCU), an editable logic controller (PLC), a Programmable Automation Controller (PAC), an industrial control computer (IPC), a Field-Programmable Gate Array (FPGA), an Application-Specific Integrated Circuit chip (ASIC chip), and the like.

As an advantageous modification, a first end portion (e.g., a position or region where the dovetail groove 920 is provided) of the first side housing 1011 in the housing 101 is provided with a first mounting groove 10112, and a second end portion (e.g., a position or region where the dovetail block 910 is provided) of the second side housing 1012 is provided with a second mounting groove 10122. And accordingly, the cable of the motor includes a first connector and a second connector (not shown), wherein the first connector is mounted to the first mounting groove 10112, and the second connector is mounted to the second mounting groove 10122. Such an arrangement enables a hidden design and also facilitates the electrical connection of the different motors while the housing 101 is connected laterally by the ends of the two side housings when the different stator assemblies 100 are mated.

Transmission mechanism

The transmission mechanism is used to transmit the output of the motor to the display portion 200. Therefore, the transmission mechanism is in transmission connection with the output shaft of the motor. Also, it is understood that, for output drive, the transmission mechanism has a drive part 1031 shown in fig. 2, which is at least partially exposed outside the housing 101. Therefore, the driving part 1031 receives power from the motor and then transmits the power to the display part 200 in cooperation therewith to rotate the same.

In some examples, when the output shaft of the motor is along the axial direction of the housing 101, it may be engaged with the display portion 200 by means of, for example, a belt drive.

In the illustrated structure of the present application, the transmission mechanism is a gear or the transmission mechanism may be a gear mechanism 300, as shown in fig. 9.

For example, referring to fig. 9, 10 and 11, gear mechanism 300 includes a carrier 201 and a gear set 202. Wherein the cage 201 is disposed in the housing cavity and serves to maintain the gear set 202 in a stable rotation in an attitude. Gear set 202 may have one or more gears. For example, the gear train 202 includes a main gear 2021 and at least one sub-gear 2022 (four in the illustrated structure), wherein the holder 201 is held in the housing cavity while the main gear 2021 and each sub-gear 2022 are engaged, and the main gear 2021 and each sub-gear 2022 are rotatably provided to the holder 201.

From the layout of the gear train 202, the main gear 2021 is located at the inner (or center) and the plurality of sub-gears 2022 are located at the outer periphery of the main gear 2021 and are uniformly distributed in a circle around the axial center line of the main gear 2021, while the output shafts of the motor of the main gear 2021 are connected. Therefore, the output of the output shaft of the motor is transmitted to the pinion 2022 through the main gear 2021, and the pinion 2022 is engaged with the display section 200. For example, pinion 2022 engages internal teeth on the inner wall of the bore of display portion 200.

In the gear mechanism 300, the holder 201 may have a disk-like structure or a frame structure formed by combining rod-like or plate-like materials. In fig. 10, the holder 201 has a first retainer plate 2011 and a second retainer plate 2012 which are opposite to each other, and the opposite direction is along the axial direction of the housing 101, i.e., a first preset direction. The two limit plates have a second crankshaft mounting hole 404 at a substantially central position for the output shaft of the motor to pass through. Meanwhile, a fixed shaft 403 connected between the two limit plates is provided around the limit plates around the second crankshaft mounting hole 404, and the pinion 2022 is rotatably fitted around the fixed shaft 403.

Accordingly, the main gear 2021 and the respective sub-gears 2022 are rotatably held between the first stopper plate 2011 and the second stopper plate 2012. Wherein the main gear 2021 and the sub gear 2022 can be rotated by one or more combinations of bearings and shafts provided between the first stopper plate 2011 and the second stopper plate 2012, and also restricted between the two fiberboards. The main gear 2021 has a first spindle mounting hole 402 through which an output shaft of the electric power machine passes; the pinion 2022 has a fixing hole 401 to be fitted with the fixing shaft 403.

The holder 201 may be fixedly arranged inside the housing 101, e.g. glued or welded, or the holder 201 is integrally formed with the housing 101. For example, a first stopper plate 2011 is integrally coupled to the first side housing 1011, and a second stopper plate 2012 is integrally coupled to the second side housing 1012. Alternatively, the holder 201 may be detachably disposed inside the housing 101. For example, referring to fig. 7 and 8, the inner surface of the first side housing 1011 has a first protrusion 10113 located within the housing cavity, and the inner surface of the second side housing 1012 has a second protrusion 10123 located within the housing cavity. As such, when the first and second side cases 1011 and 1012 are coupled, the spacing between the first and second protrusions 10113 and 10123 corresponds to or coincides with the thickness or axial height of the main and sub gears 2021 and 2022. And therefore the second projection 10123 and the second projection 10123 cooperate so as to be able to jointly define a relative separation movement of the first and second limit plates 2011, 2012 along a first preset direction. As such, when the main gear 2021 and the sub gear 2022 are disposed between the first stopper plate 2011 and the second stopper plate 2012, the mutual distance or approach of the two stopper plates in the first preset direction is restricted.
