[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1

[0023] Please refer to Figure 1 -7. This embodiment provides an electric sunshade with easy disassembly and assembly of a synchronous belt connector, including a motor 1 that provides a power source. The motor 1 transmits power to a synchronous belt 3 through a synchronous wheel 2, converting the rotational motion into up and down motion. The synchronous belt 3 then drives the curtain fabric 5 to move up and down through a synchronous belt connector 4 fixed thereon.

[0024] In the embodiments of the present utility model application, please refer to Figure 1 (front view) and Figure 2(The reverse side view) The main body of the synchronous belt connector 4 is in the shape of a square body. The upper and lower surfaces of the body (i.e., the synchronous belt connector 4) are smooth and glossy. The four sides of the body are provided with a number of ventilation grooves 6. The ventilation grooves 6 are U-shaped grooves that penetrate the synchronous belt connector 4. Since the synchronous belt connector 4 moves in the side rail aluminum profile 20, it is basically a clearance fit. The ventilation grooves 6 can balance the upper and lower air pressures, so that the synchronous belt connector 4 can move up and down smoothly. A balancing cavity 10 is provided on the body. The balancing cavity 10 is a hollow waist-shaped hole. It is to balance the weight of each area of ​​the synchronous belt connector 4, to prevent the weight on one side from tilting during movement, resulting in friction with the side rail aluminum profile 20 next to it. In addition, it can also play a role in ventilation and maintain the balance of upper and lower air pressures.

[0025] In the embodiments of the present utility model application, please refer to Figure 3 The main body is provided with a power cavity 7 for fixing the synchronous belt 3, and the power cavity 7 is provided with a rack-shaped notch that meshes with the synchronous belt 3. When working, the synchronous belt 3 only needs to be placed in the power cavity 7 to drive the synchronous belt connector 4 to move. Due to the space limitation of the side rail aluminum profile 20, the synchronous belt 3 will not fall out naturally.

[0026] In the embodiments of the present utility model application, please refer to Figure 4 , a small cavity 8 is provided on the body, and the small cavity 8 is used to place one side of the second synchronous belt 19, and a large cavity 9 is provided on the body, and the cavity is used to place the other side of the second synchronous belt 19 and one side of the first synchronous belt 18. That is, this synchronous belt connector 4 can accommodate the work of two synchronous belts 3 at the same time, or only one synchronous belt 3 can be used according to actual work needs. The synchronous belt 3 passing through the power cavity 7 is the synchronous belt 3 with original power (equivalent to the first synchronous belt 18), and the other is the synchronous belt 3 passing through the large cavity 9 and the small cavity 8 (equivalent to the second synchronous belt 19, which has no contact with this synchronous belt connector and only passes through it).

[0027] In the embodiments of the present utility model application, please refer to Figure 5 and Figure 6 A buckle bracket 11 is installed on the back of the main body. The buckle bracket 11 has a "Z" shape. The buckle bracket 11 is provided with a fixed end 12 that is clamped with the synchronous belt connector 4, a connecting end 13 that is fixedly connected to the curtain fabric 5, and a mounting hole 14. A bayonet 16 is provided on the back of the main body of the synchronous belt connector 4, and a threaded hole 17 is provided on the back of the main body of the synchronous belt connector 4. The bayonet 16 is used to accommodate the fixed end 12 of the buckle bracket 11, and then the buckle bracket 11 is fixed by a bolt passing through the buckle bracket 11 and connected to the threaded hole 17.

[0028] Furthermore, a weight reduction cavity 15 is provided on the body of the synchronous belt connector 4. The function of the weight reduction cavity 15 is to reduce the dead weight and energy consumption while satisfying various performance requirements of the synchronous belt connector 4.

[0029] The beneficial effects of the utility model are as follows: by arranging the power cavity 7, large and small cavities 8, etc. on the main body, the synchronous belt 3 can be directly fixed after being placed in the power cavity 7, and then the curtain fabric 5 can be pulled up and down by the buckle bracket 11, and the large and small cavities 8 can reserve space for placing the second synchronous belt 19.

[0030] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
