Description

Technical Field

[0001] This invention relates to the field of sunshade technology, and more particularly to an electric direct-drive sunshade. Background Technology

[0002] With the continuous development of the automotive industry, vehicles have become an indispensable means of transportation in people's daily lives. The interior environment of cars and passenger comfort have gradually received more attention. Among these, sunshades, as a commonly used sunshade device, can block sunlight, protect passengers from direct sunlight, and improve the comfort of the in-vehicle environment. However, in practical use, the sunshade device requires manual control, increasing the cumbersomeness of its operation. Therefore, we designed an electric direct-drive sunshade. Summary of the Invention

[0005] The drive unit includes rollers and a drive rope. The slider slides horizontally on the guide rail through the transmission of the rollers. The sliding of the slider drives the side strip to slide and adjust its position in the same direction.

[0006] A drive shaft is provided on one side of the guide rail. A first pulley set is fixedly installed on the top of one side of the drive shaft. A second pulley set is fixedly installed on the top of the side of the first pulley set away from the drive shaft. An inner tube is provided on one side of the drive shaft. A one-way device is provided on the surface of one side of the drive shaft. The one-way device is fixed to the inner tube. A connecting tension spring is provided between the roller and the slider.

[0007] The drive unit connects to the drive shaft, which drives the first and second spools to rotate forward. The winding drive rope pulls the slider to adjust the side strip, thus directly unfolding the sunshade. The drive unit reverses the drive shaft, which drives the one-way device and the inner tube to control the direct retraction of the sunshade. By controlling the directional operation of the one-way device, the automatic one-way unfolding and closing of the device can be guaranteed.

[0008] Preferably, the slider is located on one side surface of the guide rail, the slider and the guide rail are connected by a sliding connection, and the sunshade and the roller assembly are connected by a rewind connection.

[0009] Preferably, the connection between the roller and the drive group is a transmission connection, and the connection between the roller and the drive rope is a winding and transmission connection. The first fixed seat and the second fixed seat are symmetrically distributed at the top of both sides of the roller group.

[0010] Preferably, the first and second spool sets are symmetrically distributed on the top surfaces of both sides of the drive shaft, the one-way valve and the drive shaft are connected by a sliding connection, and the one-way valve is fixedly connected to the inner tube.

[0011] Preferably, the first spool group and the second spool group are arranged in a mirror symmetrical structure. The first spool group includes a spool, and a tension control spring is fixedly connected to one end of the spool. A connecting shaft is fixedly connected to one end of the tension control spring.

[0012] The connecting shaft slides on the drive shaft, enabling the tension control spring to be tightened and loosened.

[0013] Preferably, the drive assembly includes a fixed roller and a tension roller. An auxiliary stress-relieving spring is provided at the top of one side of the tension roller. A drive rope is wound and connected to one side surface of the fixed roller, and a drive rope is wound and connected to one side surface of the tension roller.

[0014] Preferably, the fixed roller and the tension roller are connected by the drive rope, and there are two fixed rollers, which are symmetrically distributed on both sides of the top of the tension roller.

[0015] Fixed rollers are symmetrically positioned on both sides of the tension roller to adjust the tension. The tension roller is connected to an auxiliary damping spring to adjust the tension appropriately. The fixed rollers on both sides ensure that the tension roller is subjected to uniform force.

[0016] Compared with related technologies, the electric direct-drive sunshade curtain provided by the present invention has the following beneficial effects:

[0017] 1. This invention provides an electric direct-drive sunshade curtain. The opening and closing action of the sunshade curtain is realized by setting a drive group to drive the drive shaft. When the control drive assembly makes the motor rotate, it will drive the sunshade curtain to fully open or close via the drive shaft. During the opening and closing process of the sunshade curtain, the one-way device controls the drive shaft and the inner tube to rotate freely or synchronously, thereby driving the roller group or drive sheave to wind up the drive rope, and finally realize the opening or closing of the sunshade curtain.

[0018] 2. This invention provides an electric direct-drive sunshade curtain. By adding a drive shaft and a one-way device to the central part, the synchronous drive of the two side pulleys is achieved. There are two ways to tension the sunshade curtain: First, the tension control spring inside the pulley is used to tighten the drive rope to achieve tension; second, the drive rope is tightened to tension the sunshade curtain by adding a tension roller in the middle of the drive rope or adding a connecting tension spring at the connection position between the drive rope and the slider.

[0031] The drive unit 13 includes a roller 9 and a drive rope 11. The slider 10 slides horizontally on the guide rail 4 through the transmission of the roller 9. The sliding of the slider 10 drives the side strip 8 to slide and adjust its position in the same direction.

[0032] A drive shaft 16 is provided on one side of the guide rail 4. A first pulley set 14 is fixedly installed on the top of one side of the drive shaft 16. A second pulley set 15 is fixedly installed on the top of the side of the first pulley set 14 away from the drive shaft 16. An inner tube 17 is provided on one side of the drive shaft 16. A one-way device 18 is provided on the surface of one side of the drive shaft 16. The one-way device 18 is fixed to the inner tube 17. A connecting tension spring 20 is provided between the roller 9 and the slider 10.

[0033] The drive unit 13 is connected to the drive shaft 16, which drives the first pulley group 14 and the second pulley group 15 to rotate forward. The winding drive rope 11 pulls the slider 10 to adjust the side strip 8 to realize the direct unfolding of the sunshade curtain 7. The drive unit 13 reverses the drive shaft 16 to drive the one-way device 18 and the inner tube 17 to control the direct retraction of the sunshade curtain 7. By controlling the directional operation of the one-way device 18, the automatic one-way unfolding and closing of the device can be guaranteed.

[0034] The slider 10 is located on one side surface of the guide rail 4. The slider 10 and the guide rail 4 are connected by a sliding connection.

[0035] In the implementation plan, the opening and closing action of the sunshade curtain 7 is realized by setting the drive group 13 to drive the drive shaft 16. When the control drive assembly makes the motor rotate, it will drive the sunshade curtain to fully open or close via the drive shaft. During the opening and closing process of the sunshade curtain 7, the one-way device 18 controls the drive shaft 16 and the inner tube 17 to rotate freely or synchronously, thereby driving the roller group 6 or the drive sheave 141 to wind up the drive rope 11, and finally realize the opening or closing of the sunshade curtain 7.

[0036] Example 2:

[0037] Please see Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: a first spool group 14 and a second spool group 15 are symmetrically distributed on the top surfaces of both sides of the drive shaft 16. A one-way valve 18 is fixedly connected to the inner tube 17, and the connection between the one-way valve 18 and the inner tube 17 is a sliding connection. The first spool group 14 and the second spool group 15 are arranged in a mirror symmetrical structure. The first spool group 14 includes a spool 141, and a tension control spring 142 is fixedly connected to one top surface of the spool 141. A tension control spring 142 is fixedly connected to one top surface of the spool 141. The drive assembly 13 is connected to a connecting shaft 143 and includes a fixed roller 131 and a tension roller 132. An auxiliary stress-relieving spring 133 is provided at the top of one side of the tension roller 132. A drive rope 11 is connected to one side surface of the fixed roller 131 for winding and transmission. A drive rope 11 is also connected to one side surface of the tension roller 132 for winding and transmission. The fixed roller 131 and the tension roller 132 are connected by the drive rope 11. There are two fixed rollers 131, which are symmetrically distributed on the top of both sides of the tension roller 132.

[0038] Fixed rollers 131 are symmetrically positioned on both sides of tension roller 132 to adjust the tension of tension roller 132. Tension roller 132 is connected to auxiliary stress-relieving spring 133 to adjust the tension appropriately. Fixed rollers 131 on both sides ensure that tension roller 132 is subjected to uniform force.

[0039] In the implementation case, by adding a drive shaft 16 and a one-way device 18 to the central part, the synchronization of the drive of the two side pulleys is achieved. There are two ways to tension the curtain 7: First, the drive rope 11 is tightened by the tension control spring 142 inside the pulley 141; Second, the drive rope 11 is tightened by adding a tension roller 132 in the middle of the drive rope 11 or adding a connecting tension spring 20 at the connection position between the drive rope 11 and the slider 10 to tighten the sunshade 7.

[0040] Working principle:

[0041] The opening and closing action of the sunshade curtain 7 is achieved by setting the drive group 13 to drive the drive shaft 16. When the control drive assembly makes the motor rotate, it will drive the sunshade curtain to fully open or close via the drive shaft. During the opening and closing process of the sunshade curtain 7, the one-way device 18 controls the drive shaft 16 and the inner tube 17 to rotate freely or synchronously, thereby driving the roller group 6 or the drive sheave 141 to wind up the drive rope 11, and finally realize the opening or closing of the sunshade curtain 7.

[0042] By adding a drive shaft 16 and a one-way device 18 to the central part, the synchronization of the drive of the two side pulleys is achieved. There are two ways to tension the curtain of the sunshade curtain 7: First, the tension control spring 142 inside the pulley 141 pulls the drive rope 11 to tighten it; Second, the drive rope 11 is tightened to tension the sunshade curtain 7 by adding a tension roller 132 in the middle of the drive rope 11 or adding a connecting tension spring 20 at the connection position between the drive rope 11 and the slider 10.

[0043] Sunshade curtain closing: The drive unit drives the drive shaft to rotate clockwise, which in turn drives the sheave to rotate clockwise. The sheave winds the drive rope and pulls the slider forward to close the sunshade curtain; at this time, the one-way valve and drive shaft are in an idle state.

[0044] When the sunshade is opened: the drive unit drives the drive shaft to rotate counterclockwise, and the drive shaft rotates synchronously through the one-way device to drive the inner tube to roll up the fabric, thus opening the sunshade. At this time, the one-way device and the drive shaft are rotating synchronously.
