DETAILED DESCRIPTION

[0019] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. EMBODIMENT

[0020] As shown in Figure 1 and Figure 2 , an electric drive sunshade hollow glass product includes two hollow glasses 1, a window frame 2, and a sunshade assembly 3 located in the window frame 2. The two hollow glasses 1 are located at the front and back ends of the sunshade assembly 3 and the window frame 2. The sunshade assembly 3 includes a sunshade curtain 3c, a lifting and turning assembly 3a, and an electric drive assembly 3b. The electric drive assembly 3b and the lifting and turning assembly 3a are both located at the top of the window frame 2. The sunshade curtain 3c is located below the electric drive assembly 3b and the lifting and turning assembly 3a. The electric drive assembly 3b includes a drive machine 3b1. The window frame 2 includes a mounting frame 2a. The drive machine 3b1 is located in the hollow chamber 2a1 of the mounting frame 2a. The drive machine 3b1 is connected to the lifting and turning assembly 3a through a rotating shaft. As a preferred embodiment, the present application uses a louver as the sunshade curtain 3c, but it is not excluded that other sunshade curtains that can weaken direct sunlight and block sunlight are used.

[0021] It is worth mentioning that, as shown in Figure 2 , the sunshade assembly 3 has two lifting and turning assemblies 3a. One end of the drive machine 3b1 extends outward and passes through the mounting frame 2a, and connects the two lifting and turning assemblies 3a in series through the rotating shaft 3a1. The sunshade curtain 3c has a lifting rope 3c1 and a ladder belt rope 3c2 connected in series. One end of the lifting rope 3c1 is connected to the lifting and turning assembly 3a, and the other end is connected to the crossbeam of the sunshade curtain 3c.

[0022] As shown in Figures 3-4 , the sunshade assembly 3 has two lifting and turning assemblies 3a. One end of the drive machine 3b1 extends outward and passes through the mounting frame 2a, and connects the two lifting and turning assemblies 3a in series through the rotating shaft 3a1. The sunshade curtain 3c has a lifting rope 3c1 and a ladder belt rope 3c2 connected in series. One end of the lifting rope 3c1 is connected to the lifting and turning assembly 3a, and the other end is connected to the crossbeam of the sunshade curtain 3c.As shown, the electric drive assembly 3b of the present application comprises a mounting frame 2a, a drive machine 3b1, and a speed reducer 3b2, the front end of the drive machine 3b1 is connected with the mounting frame 2a through the speed reducer 3b2, and the rear end is connected with the rear end of the mounting frame 2a through an elastic connecting piece 4, so that the drive machine 3b1 is suspended in the hollow chamber 2a1 of the mounting frame 2a, and the rotation axis of the drive machine 3b1 coincides with the rotation axis of the speed reducer 3b2, wherein the rear end of the drive machine 3b1 is provided with a connecting part 3b1a, one end of the elastic connecting piece 4 is connected with the connecting part 3b1a, and the other end is connected with the rear end of the mounting frame 2a, so that a certain movement space 6 is left between the outer wall of the drive machine 3b1 and the inner wall of the hollow chamber 2a1, wherein as a preferred scheme, two springs 4a are used as the elastic connecting piece 4, and the drive machine 3b1 is suspended in the hollow chamber 2a1 of the mounting frame 2a by being fixedly connected with the connecting parts 3b1a at the upper and lower ends of the drive machine 3b1, but other technical solutions that can suspend the drive machine 3b1 and not contact the side wall of the hollow chamber 2a1 during use are not excluded, and a fixing part 7 for fixing the mounting frame is arranged below the mounting frame.

[0023] It is worth mentioning that, as Figure 4 shown, the front end of the drive machine 3b1 is connected with the speed reducer 3b2, and the front end of the mounting frame 2a is connected through the speed reducer 3b2, wherein the mounting frame 2a is provided with a hole 2a2 for the speed reducer 3b2 to pass through, one end of the speed reducer 3b2 passes through the hole 2a2 and is connected with the drive machine 3b1, and the other end is sleeved with a buffer pad 5, and after the electric drive assembly 3b is assembled, the buffer pad 5 is just located between the inner wall of the above-mentioned hole 2a2 and the outer wall of the speed reducer 3b2. Among them, the buffer pad between the speed reducer and the mounting frame is the preferred embodiment of the present scheme, and the mode of rigid contact between the speed reducer and the mounting frame without buffer pad can also be adopted.

[0024] In summary, on the basis of the built-in sunshade hollow glass 1, the electric drive assembly 3b is used to replace the traditional manual lifting assembly. The driving machine 3b1 in the electric drive assembly 3b rotates to drive the lifting and overturning assembly 3a to work, and the sunshade curtain 3c is retracted. In order to avoid large displacement of the driving machine 3b1 during movement, the driving machine 3b1 is fixed on the window frame 2 between the two hollow glasses 1 through the mounting frame 2a. However, as the driving machine 3b1 rotates, the geometric errors existing in the process of machining and assembly will cause the driving machine 3b1 to swing to a certain extent due to the microscopic coaxial error, the problem of the mass center offset in the rotor, and the assembly precision of the speed reducer 3b2 and the lifting and overturning assembly 3a. During the swinging process, the driving machine 3b1 will impact the mounting frame 2a for fixing the driving machine 3b1 and produce vibration, and the vibration will be amplified through the solid medium such as glass and window frame 2. Not only will noise be generated during use, but also the stress concentration on the inner surface of the glass corner will be increased due to repeated high-frequency vibration. In order to avoid the above problems, a hollow cavity 2a1 is formed in the mounting frame 2a on the basis of the existing electric drive assembly 3b. The driving machine 3b1 is arranged in the hollow cavity 2a1, and a certain movement space 6 is left between the driving machine 3b1 and the inner wall of the hollow cavity 2a1 to avoid the driving machine 3b1 from impacting the mounting frame 2a during movement and producing vibration. On this basis, the connecting part 3b1a is arranged at the rear end of the driving machine 3b1 and the mounting frame 2a, and the mounting frame 2a is connected with the connecting part through the elastic connecting part 4. Since the spring 4a is used as the elastic connecting part 4, the swinging amplitude of the driving machine 3b1 can be limited by the upper and lower springs 4a, and the possibility of damage caused by the alternating load on the connection due to rigid connection can be reduced. The driving machine 3b1 can avoid directly impacting the mounting frame 2a during swinging, and the reliability of the suspension arrangement is improved. While ensuring the suspension arrangement, a certain movement space is left for the microscopic swinging of the driving machine 3b1, and the problem of large noise and resonance stress increase on the inner surface of the glass caused by the swinging of the driving machine 3b1 and the impact on the side of the mounting frame 2a is avoided from the root. Moreover, the elastic connecting part is arranged along the length direction of the driving assembly, the angular displacement of the swinging is converted into the stretching in the length direction of the elastic connecting part, which can effectively reduce the swinging amplitude of the driving machine, reduce the assembly difficulty, and further improve the use effect.

[0025] More importantly, based on the above-mentioned suspension of the drive motor 3b1 by the elastic connector 4, this application provides a hole 2a2 at the front end of the mounting frame 2a for the reducer 3b2 to pass through, and the drive motor 3b1 is connected to the mounting frame 2a through the reducer 3b2. In order to reduce the impact of the misalignment of the two axes during the assembly of the reducer 3b2 and the drive motor 3b1, a buffer pad 5 is added between the front end of the reducer 3b2 and the hole 2a2, and cooperates with the two elastic connectors 4 at the rear end of the mounting frame 2a to form a three-point connection structure, thereby improving the suspension stability of the drive motor 3b1. Example

[0026] like Figures 5-7 As shown, the structure of this embodiment is basically the same as that of Embodiment 1. The difference is that, based on Embodiment 1, this embodiment omits the buffer pad 5 and adds two additional connecting parts 3b1a located at the front end of the drive motor 3b1. The elastic connecting member 4 located at the front end is at a certain angle to the rotation center of the drive motor 3b1. While reducing the swing amplitude, the elastic connecting member 4 is tilted to limit the swing amplitude of the drive motor 3b1 and further reduce the impact of noise on it. Example

[0027] like Figures 8-10 As shown, this embodiment has a structure that is basically the same as that of embodiment one. The difference is that, based on embodiment one, this embodiment omits the buffer pad 5 and provides an elastic part 2a3 at the left end of the mounting frame. By providing a folded edge on the upper and lower sides of the elastic part 2a3, the overall strength of the mounting frame 2a is ensured while the elastic part 2a3 can generate a certain degree of elastic deformation. This allows the left side plate of the mounting frame 2a to withstand small-amplitude vibrations and prevents the vibrations from continuing to be transmitted to the rear end of the mounting frame 2a through the elastic part 2a3, further reducing the impact of noise on it.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
