Description

Technical Field

[0001] The utility model belongs to the technical field of rail vehicle equipment manufacturing, and particularly relates to a curtain structure and an electric curtain. Background Art

[0002] Existing business-class seats on rail vehicles can be rotated forward and backward at various angles as needed, and are also equipped with conference tables for face-to-face communication. However, when only one side of a double conference table is in use, the bottom of the opposite side is unused, leaving the view outside. The lack of an automatic bottom shielding device on the conference table creates a poor user experience.

[0003] In view of the above reasons, it is necessary to provide an automatic curtain structure that can automatically block the bottom of a conference table to solve the problems in the prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a curtain structure and an electric curtain to solve the problem that the bottom of a conference table cannot be automatically shielded.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A curtain barrier structure includes multiple curtain pieces and connecting strips. Two adjacent curtain pieces are connected by the connecting strips. The curtain pieces are long strips. Inlay grooves are provided on both sides of the curtain pieces along the length direction of the curtain pieces. The two ends of the connecting strip are respectively inserted into the inlay grooves of the two adjacent curtain pieces to connect the two adjacent curtain pieces.

[0007] Furthermore, the transverse cross-section of the connecting strip is dumbbell-shaped.

[0008] Furthermore, the groove walls of the two welt grooves on the same curtain sheet are raised toward the same side of the curtain sheet, and a groove is formed between the two groove walls.

[0009] Furthermore, the fillet groove is an open groove, and the width of the open groove is smaller than the widest part of the fillet groove.

[0010] Furthermore, the fillet groove is in an open arc shape.

[0011] Furthermore, the curtain blocking structure is further provided with end covers, which are adapted to the cross-section of the curtain piece and are tightly buckled onto the two end heads of the curtain piece.

[0012] Furthermore, the connecting strip is made of a rigid, elastic or soft material.

[0013] The utility model also provides an electric curtain, including a motor, a dial wheel and a connecting rod. There are two dial wheels, which are fixedly installed at both ends of the connecting rod. The dial wheels engage with the grooves of the curtain piece. The motor drives the connecting rod to rotate, and the rotating dial wheels drive the curtain to move.

[0014] Furthermore, the motor drives the connecting rod to rotate forward and reverse.

[0015] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0016] (1) Grooves are provided on the surface of the curtain. When the dial wheel rotates, the curtain automatically moves back and forth with the dial wheel. The structural design is simple and durable.

[0017] (2) The double dial wheels at the upper and lower ends of the curtain are driven synchronously, so that the curtain can slide up and down synchronously, and the use experience is smooth.

[0018] The curtain structure provided by this utility model includes multiple curtain slats and connecting strips. Two adjacent curtain slats are connected by the connecting strips. The curtain slats are elongated, and slat grooves are provided on both sides of the curtain slats along their length. The ends of the connecting strips are respectively snapped into the slat grooves of two adjacent curtain slats, connecting the two adjacent curtain slats. The utility model also provides an electric curtain slat, including a motor, a dial wheel, and a connecting rod. The dial wheels are fixedly mounted at both ends of the connecting rod. The dial wheels engage with the grooves of the curtain slats. The motor drives the connecting rod to rotate, and the rotating dial wheels drive the curtain movement.

[0019] In summary, the utility model has the advantages of beautifying appearance, sophisticated design and smooth use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Example 1

[0027] Please refer to Figure 1 and Figure 2 This embodiment provides a curtain barrier structure comprising a plurality of curtain slats 1 and a connecting strip 2. Adjacent curtain slats 1 are joined by the connecting strip 2. The curtain slats 1 are elongated, with welt grooves 3 provided on either side of the slats along their length. The ends of the connecting strip 2 are respectively inserted into the welt grooves 3 of two adjacent curtain slats 1, thereby connecting the two adjacent curtain slats 1. The connecting strip 2 has a dumbbell-shaped transverse cross-section and is made of a rigid, elastic, or soft material.

[0028] Furthermore, the walls of the two slit grooves 3 on the same curtain sheet 1 bulge toward the same side of the curtain sheet 1, forming a groove 4 between the two walls. The slit groove 3 is an arc-shaped open groove, and the width of the open groove is smaller than the widest part of the slit groove 3.

[0029] In addition, the curtain retaining structure is further provided with end covers 5 , which are adapted to the cross-sectional size of the curtain piece 1 , and the end covers 5 are tightly buckled onto the two end ends of the curtain piece 1 .

[0030] Example 2

[0031] Please refer to Figure 3 and Figure 4 This embodiment provides an electric curtain, comprising the curtain structure of embodiment 1, a connecting rod 6, a thumbwheel 1 701, a thumbwheel 2 702, and a motor 8. The thumbwheel 1 701 and the thumbwheel 2 702 are fixedly mounted on both ends of the connecting rod 6, respectively. The thumbwheel 1 701 and the thumbwheel 2 702 engage with the groove 4 of the curtain piece 1. The motor 8 drives the connecting rod 6 to rotate, and the rotating thumbwheel 1 701 and the thumbwheel 2 702 drive the curtain to move. Here, the motor 8 drives the connecting rod 6 to rotate forward and reverse, thereby realizing the forward and reverse movement of the electric curtain. A coupling 801 is provided between the motor 8 and the connecting rod 6 to increase the stability of the connecting rod 6. The motor 8 is equipped with a reduction gearbox 802 for use.

[0032] Furthermore, a conference table used in conjunction with the electric curtain provided in this embodiment is provided with a desktop 11, a bracket 10 is provided next to the desktop, an upper slide rail 901 and a lower slide rail 902 are provided under the desktop 11, and the end covers 5 at the upper and lower ends of the curtain piece 1 are respectively embedded in the tracks of the upper slide rail 901 and the lower slide rail 902.

[0033] Here, the track of the slide rail is in a V-shape with rounded corners. The first dial wheel 701 and the second dial wheel 702 are respectively arranged at the upper and lower ends of the inner side of the V-shaped round corner of the slide rail. The motor 8 drives the connecting rod 6 to rotate, driving the curtain to move in the V-shaped track of the slide rail.

[0034] Working principle:

[0035] The motor 8 is started, driving the connecting rod 6 to rotate in the forward direction. When the connecting rod 6 rotates, the dial wheel 1 701 and the dial wheel 2 702 rotate simultaneously. The dial wheel 1 701 and the dial wheel 2 702 drive the curtain along the upper slide rail 901 and the lower slide rail 902 through the groove 4 of the curtain slat 1. When the motor 8 rotates a predetermined number of times, it stops rotating, and the electric curtain reaches the specified position, completing the forward automatic stretching. Conversely, when the motor 8 drives the connecting rod 6 to rotate in the reverse direction, the electric curtain moves in the reverse direction along the upper slide rail 901 and the lower slide rail 902. After the motor 8 stops rotating, the electric curtain completes the reverse automatic stretching.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
