Description

Technical Field

[0001] This invention relates to a control device for sunshades and insect nets, and more particularly to a device for independently controlling sunshades and insect nets with a single motor, belonging to the field of automotive component technology. Background Technology

[0002] Currently, the sunshades and insect screens on the sunroofs of commercial truck cabs are typically manually operated. The sunshades and insect screens are wound onto spring-loaded retractors, which automatically retract them. The ends of the sunshades and insect screens are connected to a tow bar. The tow bar is slidably positioned on both sides of the sunroof via a damping device. The friction provided by the damping device balances the tension of the spring-loaded retractor, keeping the sunshades and insect screens open. Because the roof of a commercial truck cab is very high, manually opening and closing the sunshades and insect screens usually requires standing to reach the tow bar, forcing the driver to stand and remove both hands from the steering wheel, posing a significant driving safety hazard. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for independently controlling a sunshade curtain and an insect net with a single motor, so as to realize the independent opening and closing of the insect net and the sunshade curtain, as well as the automatic operation of opening them simultaneously.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A device for independently controlling a sunshade curtain and an insect net using a single motor includes a motor, a first transmission zipper, a second transmission zipper, an insect net, an insect net spring rewind shaft, an insect net traction rod, a sunshade curtain, a sunshade curtain spring rewind shaft, and a sunshade curtain traction rod. The first and second transmission zippers are synchronously driven by the motor. One end of the insect net is connected to the insect net spring rewind shaft, and the other end of the insect net is connected to the insect net traction rod. The insect net spring rewind shaft is located at one end of the window frame, and one end of the sunshade curtain is connected to the sunshade curtain... The traction rod is connected, and the other end of the sunshade is connected to the sunshade spring rewind shaft. The sunshade spring rewind shaft is located at the other end of the window. When both the insect net and the sunshade are open, one end of the first transmission lock and the second transmission lock abuts against the sides of the sunshade traction rod near the sunshade. The other end of the first transmission lock and the second transmission lock abuts against the sides of the insect net traction rod near the insect net. The two ends of the first transmission lock and the second transmission lock move along the length of the side edges of the window.

[0005] Furthermore, the motor is equipped with a turbine, which is fixed on the motor output shaft and driven by the motor. The outer sides of the first transmission lock and the second transmission lock are provided with worm gear spiral structures. The first transmission lock and the second transmission lock are respectively meshed with the two sides of the turbine through the worm gear spiral structures and driven synchronously by the turbine.

[0006] Furthermore, the motor is equipped with a gear, which is fixed on the output shaft of the motor and driven by the motor. The first transmission lock and the second transmission lock are equipped with a rack structure on the side near the gear. The first transmission lock and the second transmission lock are respectively meshed with the two sides of the gear through the rack structure and are driven synchronously by the gear.

[0007] Furthermore, the window body is provided with two guide rails that correspond one-to-one with the first transmission zipper and the second transmission zipper. The first transmission zipper is slidably disposed in one guide rail, and the second transmission zipper is slidably disposed in the other guide rail.

[0008] Furthermore, the guide rail has an opening at the motor location for connecting the first transmission lock and the second transmission lock to the motor.

[0009] Furthermore, the guide rails on both sides of the window have guide grooves on the side closer to the inside of the window, which are arranged along the length of both sides of the window. The two ends of the insect net traction rod are respectively slidably arranged in the guide grooves of the two guide rails and can slide freely along the length of the guide grooves. The two ends of the sunshade curtain traction rod are respectively slidably arranged in the guide grooves of the two guide rails and can slide freely along the length of the guide grooves.

[0010] Furthermore, the first and second transmission locks are made of soft steel wire rope with a certain axial rigidity. The axial rigidity of the first and second transmission locks enables them to push the insect net traction rod and the sunshade curtain traction rod.

[0011] Furthermore, the first and second transmission pulls are alternately arranged inside the window. The ends of the first and second transmission pulls that abut against the insect net traction rod can move synchronously, and the other ends of the first and second transmission pulls that abut against the sunshade traction rod can also move synchronously.

[0012] Compared with the prior art, the present invention has the following advantages and effects: 1. This invention realizes automatic driving in three modes: opening and closing the sunshade curtain alone, opening and closing the insect net alone, and opening the sunshade curtain and the insect net simultaneously. It eliminates the need for the driver to stand and operate, thus eliminating driving safety hazards. 2. This invention uses a single motor in conjunction with two transmission cables to achieve simultaneous control of the insect net and the sunshade curtain. It uses only one motor, the whole device has a simple structure, low design cost, and full functionality, and can automatically realize three control modes for the sunshade curtain and the insect net. 3. The sunshade curtain and insect net of this invention still adopt the traditional structure, only requiring the addition of two drive locks, one motor and two tracks. The adjustment to the production line is small, further reducing production costs. Moreover, it is easy to directly improve existing skylights, and the application range is wider.

[0021] To illustrate in detail the technical solutions adopted by the present invention to achieve the intended technical objectives, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Furthermore, the technical means or technical features in the embodiments of the present invention can be replaced without creative effort. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1As shown, the present invention provides a device for independently controlling a sunshade curtain and an insect net using a single motor, comprising a motor 1, a first transmission zipper 2, a second transmission zipper 3, an insect net 4, an insect net spring rewind shaft 5, an insect net traction rod 6, a sunshade curtain 7, a sunshade curtain spring rewind shaft 8, and a sunshade curtain traction rod 9. The first transmission zipper 2 and the second transmission zipper 3 are synchronously driven by the motor 1. One end of the insect net 4 is connected to the insect net spring rewind shaft 5, and the other end of the insect net 4 is connected to the insect net traction rod 6. The insect net spring rewind shaft 5 is located at one end of the window 10. One end of the sunshade curtain 7 is connected to the sunshade curtain traction rod 9, and the other end of the sunshade curtain 7 is connected to the sunshade curtain spring rewind shaft 8. The sunshade curtain spring rewind shaft 8 is located at the other end of the window 10. When both the insect net 4 and the sunshade curtain 7 are open, one end of the first transmission zipper 2 and the second transmission zipper 3 abuts against the sides of the sunshade curtain 7 near the ends of the sunshade curtain traction rod 9, and the other end of the first transmission zipper 2 and the second transmission zipper 3 abuts against the sides of the insect net traction rod 6 near the ends of the insect net 4. The two ends of the first transmission zipper 2 and the second transmission zipper 3 move along the length of the side edges on both sides of the window 10.

[0023] like Figure 2 As shown, in one embodiment of the present invention, a turbine 11 is provided on the motor 1. The turbine 11 is fixed on the output shaft of the motor 1 and driven by the motor 1. A worm gear helical structure is provided on the outer side of the first transmission lock 2 and the second transmission lock 3. The first transmission lock 2 and the second transmission lock 3 respectively mesh with the two sides of the turbine 11 through the worm gear helical structure and are driven synchronously by the turbine 11. The motor 1 is a geared motor or a gearbox is added to a separate motor to reduce the driving speed of the motor 1.

[0024] In another embodiment of the present invention, a gear is provided on the motor 1, the gear is fixed on the output shaft of the motor 1 and driven by the motor 1, and a rack structure is provided on the side of the first transmission lock 2 and the second transmission lock 3 near the gear. The first transmission lock 2 and the second transmission lock 3 respectively mesh with the two sides of the gear through the rack structure and are driven synchronously by the gear.

[0025] like Figure 3 As shown, the window 10 has two guide rails 12 that correspond one-to-one with the first transmission zipper 2 and the second transmission zipper 3. The first transmission zipper 2 is slidably mounted in one guide rail 12, and the second transmission zipper 3 is slidably mounted in the other guide rail 12. The guide rails 12 have openings at the motor 1 for connecting the first transmission zipper 2 and the second transmission zipper 3 to the motor 1.

[0026] The guide rail 12 on both sides of the window 10 has a guide groove on the side closer to the inside of the window 10, which is set along the length of both sides of the window 10. The two ends of the insect net traction rod 6 are respectively slidably set in the guide grooves of the two guide rails 12 and can slide freely along the length of the guide grooves. The two ends of the sunshade curtain traction rod 9 are respectively slidably set in the guide grooves of the two guide rails 12 and can slide freely along the length of the guide grooves.

[0027] The first transmission cable 2 and the second transmission cable 3 are made of soft steel wire rope with a certain axial rigidity. The axial rigidity of the first transmission cable 2 and the second transmission cable 3 enables them to push the insect net traction rod 6 and the sunshade curtain traction rod 9. The first transmission cable 2 and the second transmission cable 3 are staggered inside the window 10. The ends of the first transmission cable 2 and the second transmission cable 3 that abut against the insect net traction rod 6 can move synchronously, and the other ends of the first transmission cable 2 and the second transmission cable 3 that abut against the sunshade curtain traction rod 9 can also move synchronously.

[0028] The working principle of the device for independently controlling a sunshade curtain and an insect net by a single motor according to the present invention is as follows: For ease of explanation, we will refer to the end where the first transmission zipper 2 and the second transmission zipper 3 abut against the sunshade curtain traction rod 9 as the head end, and the end where the first transmission zipper 2 and the second transmission zipper 3 abut against the insect net traction rod 6 as the tail end.

[0029] In the initial state, such as Figure 1 As shown, both the insect net 4 and the sunshade curtain 7 are in the open state. At this time, the head and tail ends of the first transmission zipper 2 are abutting against the sunshade curtain traction rod 9 and the insect net traction rod 6 but not in contact. The head and tail ends of the second transmission zipper 3 are abutting against the sunshade curtain traction rod 9 and the insect net traction rod 6 but not in contact.

[0030] When the sunshade 7 is closed, motor 1 rotates clockwise, as... Figure 4 As shown, the head ends of the first transmission zipper 2 and the second transmission zipper 3 begin to move upward and push the sunshade curtain traction rod 9 upward, and the sunshade curtain 7 begins to close. At the same time, the tail ends of the first transmission zipper 2 and the second transmission zipper 3 begin to move away from the upper side of the insect net traction rod 6.

[0031] like Figure 5 As shown, when the sunshade curtain traction rod 9 moves upward to contact the insect net traction rod 6, the sunshade curtain 7 is completely closed, the motor 1 stops rotating and self-locks, and the self-locking force of the motor 1 is balanced with the tension of the sunshade curtain spring winding shaft 8, so the sunshade curtain 7 remains closed.

[0032] When the sunshade 7 is opened, as Figure 6As shown, motor 1 rotates counterclockwise, and the head ends of the first transmission zipper 2 and the second transmission zipper 3 begin to move downward. Under the pulling force of the sunshade curtain spring rewind shaft 8, the sunshade curtain traction rod 9 moves downward together with the head ends of the first transmission zipper 2 and the second transmission zipper 3, completing the opening of the sunshade curtain 7. At the same time, the tail ends of the first transmission zipper 2 and the second transmission zipper 3 continuously move closer to the insect net traction rod 6.

[0033] like Figure 1 As shown, when the sunshade curtain pull rod 9 descends to its lowest position, the motor 1 stops rotating, completing the closing of the sunshade curtain 7. At this time, the tail ends of the first transmission lock 2 and the second transmission lock 3 are in contact with the insect net pull rod 6.

[0034] When the insect screen 4 is closed, motor 1 rotates counterclockwise, as follows: Figure 7 As shown, the tail ends of the first transmission zipper 2 and the second transmission zipper 3 begin to move downward and push the insect net traction rod 6 downward, and the insect net 4 begins to close. At the same time, the head ends of the first transmission zipper 2 and the second transmission zipper 3 begin to move away from the lower side of the sunshade curtain traction rod 9.

[0035] like Figure 8 As shown, when the insect net traction rod 6 moves downward to contact the sunshade curtain traction rod 9, the insect net 4 is completely closed, the motor 1 stops rotating and self-locks, and the self-locking force of the motor 1 is balanced with the tension of the insect net spring winding shaft 5, so the insect net 4 remains closed.

[0036] When the insect net 4 is opened, the motor 1 rotates clockwise, and the tail ends of the first transmission zipper 2 and the second transmission zipper 3 begin to move upward. Under the pulling force of the insect net spring winding shaft 5, the insect net traction rod 6 moves upward together with the tail ends of the first transmission zipper 2 and the second transmission zipper 3, thus completing the opening of the insect net 4. At the same time, the head ends of the first transmission zipper 2 and the second transmission zipper 3 continuously move closer to the sunshade curtain traction rod 9.

[0037] like Figure 1 As shown, when the insect net traction rod 6 rises to its highest position, the motor 1 stops rotating, completing the opening of the insect net 4. At this time, the heads of the first transmission lock 2 and the second transmission lock 3 just come into contact with the sunshade curtain traction rod 9, returning to the initial state.

[0038] This invention achieves automatic operation in three modes: independent opening and closing of the sunshade curtain, independent opening and closing of the insect net, and simultaneous opening of both the sunshade curtain and the insect net. This eliminates the need for a driver to stand and operate the equipment, thus removing driving safety hazards. The invention uses a single motor with two drive cables to simultaneously control both the insect net and the sunshade curtain. Using only one motor, the entire device has a simple structure, low design cost, and comprehensive functionality, automatically implementing the three control modes for both the sunshade curtain and the insect net. The sunshade curtain and insect net still use a traditional structure, requiring only the addition of two drive cables, one motor, and two tracks. This minimizes adjustments to the production line, further reducing production costs, and allows for easy modification to existing sunroofs, broadening its application range.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments without departing from the scope of the present invention, based on the technical essence of the present invention and within the spirit and principles of the present invention, shall still fall within the protection scope of the present invention.
