Referring to fig. 1, 2A and 2B, the building exterior wall device of the present invention includes a fixing unit 1 and at least one shielding unit 2 pivoted to the fixing unit 1, and the drawings illustrate one shielding unit 2 as an example, but not limited thereto, wherein the building exterior wall device of the present invention is disposed on a building exterior wall (not shown) through the fixing unit 1, so that the building exterior wall can be shielded by the shielding unit 2, thereby reducing sunlight irradiating on the building exterior wall.

The fixing unit 1 comprises two upright posts 11 arranged at intervals for the shielding unit 2 to be pivoted between the two upright posts 11, more specifically, the fixing unit 1 can be a fixing frame erected on an outer wall of a building so that the shielding unit 2 can be erected thereon; in addition, the shielding unit 2 is mainly used for sensing temperature variation and adjusting shading, and includes a body 21, an actuating component 22 and a heat transfer component 23.

The main body 21 includes a light shielding member 211 and an extending member 213, the light shielding member 211 is pivoted between the two columns 11 for shielding sunlight from directly irradiating on the building outer wall, the pivot joint of the light shielding member 211 and the fixing unit 1 protrudes out of the extending member 213, further, the light shielding member 211 can be a grating plate, in this embodiment, a plurality of blades can be pivoted on the grating plate, each blade is downwardly suspended from the joint with the grating plate, that is, the grating plate and the plurality of blades form a louver frame, so that air can flow in the gap between the grating plates to achieve the effects of light shielding and ventilation, accordingly, the main body 21 can shield the building outer wall through the grating plate and each blade to reduce the sunlight irradiation. In addition, the main body 21 further includes a wind shield 212 downwardly suspended from the pivot joint, that is, the wind shield 211 and the wind shield 212 are pivoted to the upright post 11 of the fixing unit 1 with the same axis, the wind shield 212 is made of a transparent material (such as glass or transparent plastic) and has no gap on its surface, so that light can pass through the wind shield, but air circulation is blocked, thereby achieving the light transmitting and wind shielding effects.

The actuating assembly 22 is disposed on one of the two uprights 11 and has a connecting member 223 pivotally connected to the extending member 213, a first elastic member 221 having one end connected to the upper portion of the connecting member 223 and the other end fixed to the upright 11, and a second elastic member 222 having one end connected to the lower portion of the connecting member 223 and the other end fixed to the upright 11, wherein the first elastic member 221 and the second elastic member 222 are linked with the extending member 213 through the connecting member 223, that is, the first elastic member 221 and the second elastic member 222 can drive the extending member 213 in the process of elastic balance, and when the whole elastic balance is achieved, the extending member 213 is maintained at a fixed position.

In practical implementation, the actuating assembly 22 may further include an upper fixing member 224 and a lower fixing member 225 fixed on the upright 11, and more specifically, one end of the first elastic member 221 is fixed to the upper fixing member 224, and the other end is connected to the connecting member 223, and one end of the second elastic member 222 is fixed to the lower fixing member 225, and the other end is connected to the connecting member 223, and is connected to the first elastic member 221 and the second elastic member 222 through the connecting member 223, so that during the elastic action between the first elastic member 221 and the second elastic member 222, the connecting member 223 moves between the upper fixing member 224 and the lower fixing member 225, so that the first elastic member 221 and the second elastic member 222 are linked to the light shielding member 211 through the connecting member 223, so as to enable the light shielding member 211 to swing correspondingly.

In one embodiment, the first elastic member 221 may be a memory spring made of a memory alloy, and the second elastic member 222 is a non-memory spring, that is, the second elastic member 222 is a general spring, and in one embodiment, the memory spring is a contractible memory spring and has an initial shape, and after the contractible memory spring is subjected to tensile deformation, when the contractible memory spring encounters an environment with a higher temperature (e.g., above 40 ℃), the memory spring contracts and gradually returns to the initial shape. For example, when the first elastic member 221 is a retractable memory spring, the first elastic member 221 is heated to be contracted, and at this time, the extending member 213 and the second elastic member 222 are driven or pulled, and finally, when the first elastic member 221 and the second elastic member 222 reach elastic equilibrium, the extending member 213 stops and maintains at a fixed position, and at this time, the light shielding member 211 is turned up to shield light, and in addition, when the environmental temperature is reduced (for example, lower than 40 ℃), the first elastic member 221 can be pulled by the second elastic member 222 to be extended and deformed, so that when the first elastic member 221 and the second elastic member 222 are at low temperature elastic equilibrium, the extending member 213 maintains at another fixed position, so that the light shielding member 211 hangs down.

The heat transfer assembly 23 has a heat absorbing element 231 disposed on the light shielding member 211 and a heat releasing element 232 disposed on a side of the first elastic member 221, above the heat absorbing element 231 and connected to the heat absorbing element 231, wherein the heat absorbing element 231 is disposed on the light shielding member 211 (e.g., a grid plate), as shown in the figure, when the light shielding member 211 is implemented as a grid plate, the heat absorbing element 231 meanders on the grid plate, and the grid plate may have a groove for the heat absorbing element 231 to be embedded therein, so that when sunlight irradiates the light shielding member 211 and the heat absorbing element 231, the heat absorbing element 231 can fully absorb heat energy of the sunlight and then transmit the heat energy to the heat releasing element 232 for releasing heat. Further, the heat releasing element 232 is disposed at a side of the first elastic element 221, so that when the heat absorbing element 231 transfers heat energy to the heat releasing element 232 for heat releasing, the first elastic element 221 is heated, and the first elastic element 221 returns to an initial state when heated to a critical temperature, and further pulls the extending element 213, that is, in the present invention, the first elastic element 221 (i.e., a shrinkage type memory spring) is shrunk to return to the initial state when heated, and further pulls the extending element 213, and after the first elastic element 221 and the second elastic element 222 reach elastic balance, the extending element 213 is maintained at a fixed position, so that the light shielding element 211 can be adjusted in orientation or angle by temperature change, thereby achieving a better light shielding effect.

In order to increase the heat dissipation effect of the heat dissipation element 232 at the first elastic element 221, the heat transfer assembly 23 further includes a heat dissipation member 233 contacting the heat dissipation element 232 and surrounding the first elastic element 221, wherein the heat dissipation member 233 may be a metal tube or a fin type heat sink. In the embodiment where the heat dissipating member 233 is a metal tube, the first elastic member 221 can be accommodated in the metal tube, that is, the first elastic member 221 penetrates through the metal tube, such that one end of the first elastic member 221 is fixed on the pillar 11, and the other end is connected to the connecting member 223, so that when the heat dissipating element 232 dissipates heat, the metal tube receives heat energy to heat the interior thereof. In addition, in the embodiment where the heat sink 233 is a fin-type heat sink, the heat dissipation element 232 can effectively dissipate heat at the position of the first elastic member 221, so that the temperature around the first elastic member 221 reacts faster, the first elastic member 221 can be heated accordingly, and the first elastic member 221 is also returned to the initial state by the temperature change, thereby forming a power for pulling the extension member 213.

In a specific implementation, the heat transfer component 23 may be a gravity assisted heat pipe, that is, the heat absorbing element 231 and the heat releasing element 232 are communicated pipes, and the heat absorbing element 231 contains liquid, after the heat transfer component 23 absorbs the heat energy of sunlight through the heat absorbing element 231, the liquid in the heat absorbing element 231 (gravity assisted heat pipe) is vaporized into gas, the gas is guided to the heat releasing element 232 through the heat absorbing element 231, and then the heat is released through the heat releasing element 232 through the heat dissipating element 233 (metal pipe or fin radiator), so that the temperature of the first elastic element 221 is raised, and the first elastic element 221 is subjected to a temperature change to generate a corresponding change, and the extending element 213 is pulled, and at this time, the light shielding element 211 is pivoted under the linkage of the extending element 213. In addition, as shown in fig. 2B, to assist the light shielding member 211 to pivot, the heat transfer assembly 23 further includes a flexible tube 234 connecting and communicating the heat releasing element 232 and the heat absorbing element 231, in one embodiment, the flexible tube 234 may be disposed near the pivot of the light shielding member 211, so that when the light shielding member 211 pivots, the flexible tube 234 is disposed at the pivot via the heat transfer assembly 23 to reduce the resistance of the light shielding member 211 when pivoting.

Fig. 3 is a schematic diagram of the architecture of the building exterior wall device of the present invention in an array arrangement. As shown in the drawings, in order to completely shield the exterior wall of the building, a plurality of shielding units 2 may be disposed at the same time, and each shielding unit 2 may be pivoted between two vertical columns 11 in an arrangement manner, further, the fixing unit 1 of the present invention may further include a plurality of vertical columns 11, and the plurality of vertical columns 11 are disposed in a spaced-apart manner, so that the two vertical columns 11 include the plurality of shielding units 2, and the plurality of vertical columns 11 are combined into an array concept, for example, 10 × 10 or 15 × 20, so that the plurality of shielding units 2 may be disposed in the array architecture. In the specific implementation, in two adjacent shielding units 2, the respective actuating components 22 are respectively disposed on the two side columns 11 in a left-right staggered manner, so as to achieve better light shielding effect by being fully distributed on the building outer wall.

Fig. 4 is an exploded view of an electric control unit of the building exterior wall device of the present invention. As shown in the figure, referring to fig. 1, the shielding unit 2 of the present invention further includes an electric control unit 24, the electric control unit 24 is driven by electric power to control the main body 21, wherein the electric control unit 24 includes a control module 241, a motor 242 electrically connected to the control module 241 and used for driving the main body 21, and a network module (not shown) electrically connected to the control module 241, the motor 242 may be specifically a stepping motor, and the motor 242 is fixed on the light shielding member 211 and is used for driving the light shielding member 211 and the wind shielding plate 212 to rotate. In one embodiment, the motor 242 can be a stepper motor with a brake and an electromagnetic clutch. In another embodiment, the electromagnetic clutch can use a "normally closed" specification, and cannot rotate without being energized, so that the angle between the light shielding member 211 and the wind shielding plate 212 is a certain value. Specifically, the electronic control unit 24 can receive a control command through the control module 241, the control module 241 is configured to convert the control command into a control signal, the motor 242 is controlled by the control signal to electrically adjust the swing angle of the main body 21, the electronic control unit 24 can be connected to the internet through a network module, and at this time, a remote user can control the electronic control unit 24 through the internet by using a handheld device or a computer, so as to control the light shielding member 211 of the main body 21, and adjust the light shielding member 211 to a position or an angle required by the user.

In addition, the electronic control unit 24 may further include an inclination sensor 243 disposed at the pivot of the light shielding member 211, a switch 25 disposed between the wind shielding plate 212 and the light shielding member 211 and electrically connected to the motor 242, and a cover 26 for covering the electronic control unit 24, wherein the inclination sensor 243 may sense the inclination angle of the rotated light shielding member 211, and the switch 25 disposed between the wind shielding plate 212 and the light shielding member 211 may be a micro switch, so that when a user adjusts the light shielding member 211 in an electric manner, when the light shielding member 211 drops to the position where the switch 25 (micro switch) is touched, the motor 242 is stopped to operate, thereby preventing the light shielding member 211 from colliding with the wind shielding plate 212 to cause damage.

In summary, the building exterior wall device of the present invention utilizes the heat transfer component formed by the gravity heat pipe to rapidly transfer the heat energy generated by the sunlight irradiation from the heat absorbing element to the heat releasing element, and the heat dissipating element disposed at the heat releasing element effectively heats the first elastic element to make the first elastic element shrink after being heated and return to the initial state, so that the first elastic element shrinks to pull the shading element to generate an angle change due to the deformation, and further the shading element correspondingly generates different shading angle changes in cooperation with different sunlight angles, thereby achieving the purpose of greatly improving the shading effect.
