[0059] The new energy lighting and heating device described in the present invention will be further explained and illustrated below in conjunction with the drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an improper limitation on the technical solution of the present invention.

[0060] In order to ensure production, the factory needs sufficient lighting. In winter, the sunlight is insufficient, and the lights need to be turned on during the day, which consumes a lot of energy. In addition, in order to ensure a constant temperature in the workshop, the air conditioner must be turned on in winter to heat the workshop to increase the temperature of the workshop. All of the above consumes a lot of energy.

[0061] In order to solve the above problems, the present invention aims to provide a new energy lighting and heating device. Figure 1 As shown, the present invention adjusts the angle of the reflector 1 so as to reflect the sunlight S into the room H through the window W according to the sunlight angle under different sunlight conditions, thereby providing light and heat energy for the indoor environment and reducing energy consumption.

[0062] Figure 2 A schematic diagram of the three-dimensional structure of the new energy lighting and heating device described in the present invention in one embodiment is shown.

[0063] Figure 3 The structure of each component inside the shell of the new energy lighting and heating device described in the present invention in one embodiment is shown.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments, the new energy lighting and heating device may include:

[0065] The housing 2 comprises a flip cover assembly 3, which is arranged on the housing 2. The flip cover assembly 3 comprises a cover plate 31, at least two flip cover brackets 32 connected to the cover plate 31, and a flip cover rotating shaft 33 connected between the at least two flip cover brackets 32. The reflector 1 is arranged in the housing and can extend from the housing 2. The reflector 1 is used to reflect sunlight from the external environment into the indoor space.

[0066] The reflector lifting assembly 4 includes a lifting base 41, on which the reflector 1 is arranged. The driving assembly 5 is connected to the cover shaft and the reflector lifting assembly to drive the cover shaft to move and drive the cover plate 31 to open relative to the shell 2, and also drive the reflector lifting assembly to drive the reflector 1 to extend from the shell. The pitch assembly 6 is arranged on the lifting base, and the pitch assembly 6 is arranged to adjust the pitch angle of the reflector 1. The steering assembly 7 is arranged on the lifting base, and the steering assembly is arranged to make the reflector 1 rotate around its own rotation axis.

[0067] like Fig. 9 As shown, there is an angle α between the geometric axis perpendicular to the reflector 1 and the rotation axis of the vertically arranged reflector. In this way, the focusing reflection of sunlight can be achieved by rotating the reflector around its own rotation axis in coordination with the adjustment of the pitch angle.

[0068] In some more specific embodiments, the reflector 1 is a device obtained by parabolic rotation and the surface of which is coated with reflective paint.

[0069] In some more specific embodiments, the driving assembly 5 may include: a lifting motor 51; a rocker arm 52, whose rear end is connected to the output shaft of the lifting motor 51 through a square hole F to achieve torque output, and the head end of the rocker arm 52 is connected to the reflector lifting assembly 4; a lifting rod 53, whose rear end is hinged to the head end of the rocker arm 52, and the head end of the lifting rod 53 is connected to the flip cover shaft 33.

[0070] In this way, the lifting motor 51 can output torque to drive the rocker 52 to rotate around its tail end. The rotation of the rocker 52 will drive the lifting rod 53 to rotate, thereby further driving the flip cover bracket 32 ​​to move upward and rotate through the flip cover shaft 33, thereby opening the cover 31.

[0071] In some more preferred embodiments, a Y-shaped groove 21 is provided on the housing 2 to provide guidance for the upward movement and rotational movement of the flip cover bracket 32 ​​.

[0072] Figure 4 for Figure 2 A partial enlarged view of point I in the middle.

[0073] Figure 5 A schematic structural diagram of a flip-cover bracket of the new energy lighting and heating device described in the present invention in one embodiment is shown.

[0074] like Figure 2 and Figure 4 As shown, in some embodiments, the side wall of the housing 2 is provided with a Y-shaped groove 21 extending in the height direction, and the upper end of the Y-shaped groove has an arc segment 211 .

[0075] like Figure 5 As shown, the flip cover bracket 32 ​​includes an arc portion 321, the upper end of the arc portion 321 is fixedly connected to the cover plate 31, and the lower end of the arc portion 321 has a first flip cover bracket stop pin 322 and a second flip cover bracket stop pin 323 extending outward. In the process of opening the cover plate 31 relative to the housing, the first flip cover bracket stop pin 322 slides from bottom to top along the Y-shaped groove 21, and the second flip cover bracket stop pin 323 enters the arc segment 211 of the Y-shaped groove 21 and slides from bottom to top along the arc segment 211. At the same time, the lower end of the arc portion 321 also has a flip cover bracket transmission pin 324 extending away from the second flip cover bracket stop pin 323, which is arranged as the flip cover rotating shaft 33. In some embodiments, a sleeve can be arranged on the outer surface of the flip cover bracket transmission pin 324 of the two flip cover brackets arranged opposite to each other, and they are jointly used as the flip cover rotating shaft 33.

[0076] In some more preferred embodiments, in order to prevent the first flip cover bracket limiting pin 322 from mistakenly entering the arc segment 211 during the process of the flip cover bracket sliding upward relative to the housing, as shown in FIG. Figure 4 As shown, a guide locking block 22 may be further provided, which is slidably disposed on the outer wall of the housing through a guide groove 23 on the outer wall of the housing.

[0077] In some more preferred embodiments, Figure 4 As shown, a spring seat 25 can also be fixedly set on the outer wall of the shell, one end of the guide lock block spring 24 is fixedly connected to the spring seat 25, and the other end is connected to the guide lock block 22. The guide lock block spring can be subjected to both compression and tension, thereby ensuring the upper and lower limit positions of the guide lock block.

[0078] like Figure 6 As shown, in some more specific embodiments, the guide lock block 22 has an arc segment R for adapting to the flip cover bracket.

[0082] In this way, the rotation of the rocker 52 drives the horizontal rack 42 to move horizontally along the horizontal rack guide boss 26 on the housing. The horizontal rack 42 drives the gear 43 to rotate, and the gear 43 drives the vertical rack 45 to move upward, thereby driving the lifting base 41 upward through the lever 451.

[0083] like Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments, the pitch assembly 6 may include: a pitch motor 61 fixed on a lifting base, the output shaft of the pitch motor passing through a hole on the lifting base and movably fitted; a first pitch pulley 62, rotatably provided on the lifting base 41 and connected to the output shaft of the pitch motor 61; a second pitch pulley 64, rotatably provided on the lifting base; a first conveyor belt 65, wrapped around the first pitch pulley 62 and the second pitch pulley 64; a pitch element 63, fixedly connected to the second pitch pulley 64 to achieve synchronous rotation, and the rotating shaft of the reflector is rotatably provided on the pitch element 63 through the first mounting hole 631.

[0084] In this way, the pitch motor 61 rotates to drive the first pitch pulley 62 to rotate, and then transmits the rotation to the second pitch pulley 64 and the pitch element 63 fixedly connected thereto through the first transmission belt 65, thereby achieving the purpose of rotating the pitch element around the pitch axis 66, thereby controlling the pitch movement of the reflector.

[0085] In some more specific embodiments, the steering assembly 7 may include: a steering motor 71, which may be disposed on a steering motor platform 413 of the lifting base 41 (eg, Figure 7 a first steering pulley 74 connected to the output shaft of the steering motor; a second steering pulley 75 fixedly connected to the rotating shaft of the reflector, such as Fig.17As shown, the second deflection pulley 75 can also be integrally formed with the rotating shaft of the reflector; the second conveyor belt 76 is wrapped around the first deflection pulley 74 and the second deflection pulley 75.

[0086] In this way, the steering motor 71 drives the first steering pulley 74 to rotate, and then drives the second steering pulley 75 to rotate, so that the reflector rotates.

[0087] In some more preferred embodiments, Fig.12 As shown, the steering assembly may further include a plurality of guide wheels 77, which are arranged along the moving direction of the second conveyor belt 76 and disposed on the outer side of the second conveyor belt 76 to guide the movement of the second conveyor belt.

[0088] In some more specific embodiments, Fig.13 As shown, a second mounting hole 632 may be opened on the pitch element 63, and the guide wheel 77 is movably connected in the second mounting hole through hole-shaft cooperation.

[0089] In some embodiments, Fig.15 and Fig.18 As shown, the steering assembly also includes: a steering motor slider 72, which is slidably connected to the lifting base 41, and the steering motor 71 and the first steering pulley 74 are both arranged on the steering motor slider 72; a tensioning spring 73, which is arranged between the steering motor slider 72 and the lifting base 41, so that the first steering pulley has a tendency to move away from the second steering pulley.

[0090] In some more specific embodiments, Figure 7 As shown, a steering motor platform 413 is provided on the lifting base 41, and a through groove 421 and a horizontal dovetail groove 422 are provided on the steering motor platform. The steering motor 71 is fixed on the steering motor slider 72.

The tensioning spring seat 78 is fixedly connected to the end face of the steering motor platform 413, thereby realizing a fixed connection with the lifting base. The tensioning spring 73 is supported between the tensioning spring seat 78 and the steering motor slider, that is, it is arranged between the steering motor slider 72 and the lifting base 41, so that the first steering pulley has a tendency to move away from the second steering pulley, thereby always keeping the tension of the second conveyor belt.
