Abstract
Description
Technical Field
[0001] This invention relates to a car curtain, and more particularly to an electric curtain. Background Technology
[0002] Motorized car curtains feature a support frame on the back of the curtain to keep it upright when pulled down. Since motorized curtains are designed to fit different car models, and different models require different curtain sizes, previously custom-made support frames were needed for each type of motorized curtain. This increased the number of parts and product costs, necessitating an improvement. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides an electric curtain in which the length of the connecting rods forming the support frame is adjustable, greatly reducing the number of parts and lowering costs.
[0004] The technical solution adopted by this invention to solve its technical problem is as follows: an electric curtain, including a curtain box, a curtain fabric, and a support frame. The upper end of the curtain fabric is rolled inside the curtain box, and the lower end of the curtain fabric is fixed to a horizontal beam. The support frame includes several connecting rods. One end of the upper connecting rod is connected to the curtain box, and one end of the lower connecting rod is connected to the horizontal beam. The other ends of the upper and lower connecting rods are hinged together. Each connecting rod includes a sleeve and a connector. The connector is inserted into the sleeve, and the end of the connector inserted into the sleeve has several through holes. After the sleeve is pressed, a portion of it extends into the through holes to form a fixed position. In use, the length of the connecting rod can be adjusted by adjusting the position of the connector in the sleeve. After adjustment, the sleeve and connector are pressed together using a device. During the pressing process, part of the material in the sleeve enters the through holes, which can fix the position of the connector and ensure that the length of the connecting rod will not change after assembly. The length of the connecting rods that make up the support frame can be adjusted in this way, and the same parts can be used for a large number of curtains, which greatly reduces the number of parts and lowers the cost.
[0005] In the above technical solution, preferably, there are two through holes.
[0006] In the above technical solution, preferably, the curtain box and the crossbeam are provided with sliding grooves, and the connecting rod is connected to the sliding grooves by a fixing mechanism. The fixing mechanism includes a bolt and a nut, the bolt head is located in the sliding groove, and the bolt shank extends out of the sliding groove, passes through the connector, and is connected to the nut. After the sliding groove is provided, the connecting rod can be set at any position within the sliding groove. Once determined, the position is fixed by tightening the nut, which also facilitates the adjustment of the connecting rod's position.
[0007] In the above technical solution, preferably, there are two connecting rods located at the top and two connecting rods located at the bottom.
[0008] In the above technical solution, preferably, the ends of the upper connecting rod and the lower connecting rod that are rotatably connected are located near the middle of the curtain.
[0009] The beneficial effects of this invention are as follows: During use, the length of the connecting rod can be adjusted by changing the position of the connector within the sleeve. After adjustment, the sleeve and connector are pressed together using equipment. During the pressing process, the upper part of the sleeve material enters the through hole, which can fix the position of the connector, ensuring that the length of the connecting rod will not change after assembly. In this way, the length of the connecting rod forming the support frame can be adjusted, allowing the same components to be used for a large number of curtains, greatly reducing the number of components and lowering costs.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0014] See Figures 1 to 3 An electric curtain includes a curtain box 1, a curtain fabric 2, and a support frame 3. The upper end of the curtain fabric 2 is rolled inside the curtain box 1, and the lower end of the curtain fabric 2 is fixed to a crossbeam 4. The support frame 3 includes four connecting rods 31, with two connecting rods 31 located at the top and two connecting rods 31 located at the bottom.
[0015] One end of the upper connecting rod 31 is connected to the curtain box 1, and the other end of the lower connecting rod 31 is connected to the crossbeam 4. Specifically, in this embodiment, the curtain box 1 and the crossbeam 4 are provided with sliding grooves 1a and 4a. The connecting rod 31 is connected to the sliding grooves 1a and 4a by a fixing mechanism 5. The fixing mechanism 5 includes a bolt 51 and a nut 52. The head of the bolt is located in the sliding groove, and the shank of the bolt extends out of the sliding groove, passes through the connector, and is connected to the nut. After the sliding groove is set, the connecting rod can be set at any position in the sliding groove. After determining the position, the position is fixed by tightening the nut, which also makes it easy to adjust the position of the connecting rod.
[0016] The upper connecting rod 31 and the lower connecting rod 31 are hinged together at their other ends, and the upper connecting rod 31 and the lower connecting rod 31 are rotatably connected at one end, which is close to the middle of the curtain 2.
[0017] The connecting rod 31 includes a sleeve 311 and a connector 312. The connector 312 is inserted into the sleeve 311. The end of the connector 312 inserted into the sleeve has two through holes 313. After the sleeve 311 is pressed, part of it extends into the through holes 313 to form a fixed shape.
[0018] In use, we can adjust the length of the connecting rod by adjusting the position of the connector inside the sleeve. After adjustment, we use equipment to press the sleeve and connector together. During the pressing process, the upper part of the sleeve enters the through hole, which can fix the position of the connector and ensure that the length of the connecting rod will not change after assembly. In this way, the length of the connecting rod of the support frame can be adjusted, and the same parts can be used for a large number of curtains, greatly reducing the number of parts and lowering costs.
