Description

Technical Field

[0001] The utility model relates to the technical field of vehicle glass sunshades, in particular to an electric sunshade curtain. Background Art

[0002] In recent years, with the rapid development of new energy vehicles, more and more users have begun to pay attention to the interior decoration of the vehicle and require the vehicle to have good comfort. Among them, the sunshade curtain is a conventional accessory, which is widely used on the front windshield, side windows, rear windshield and skylight of the vehicle.

[0003] Currently, the main function of the sunshade curtain applied to vehicles is to block sunlight. It can block sunlight, ultraviolet rays and heat from entering the vehicle, effectively reduce the temperature inside the vehicle, improve the energy efficiency ratio of the air conditioner, and save energy and costs. In addition, the sunshade curtain can also block the outside view and prying eyes and protect the privacy inside the vehicle. Currently, the existing sunshade curtains can be divided into "manual" and "electric" according to the driving method. As the name implies, "manual" means that the sunshade curtain is driven manually to open and close; "electric" means that the sunshade curtain is driven by a motor to open and close.

[0004] For the convenience of structural design and layout, the curtain cloth of the existing electric sunshade curtain is usually rectangular, and the winding direction of the curtain cloth is the same as the moving direction of the curtain cloth, that is, for the traditional electric sunshade curtain, the curtain cloth is rectangular after being fully opened. However, it is found that once faced with the shading requirement of non-rectangular glass, a non-rectangular curtain cloth must be designed and adopted; for non-rectangular curtain cloth, especially the special-shaped curtain cloth with an asymmetric structure, the existing traditional electric sunshade curtain structure cannot drive it to open and close well. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is: to provide an electric sunshade curtain to solve the problem that the existing electric sunshade curtain structure cannot drive the special-shaped curtain cloth with an asymmetric structure to open and close well.

[0006] To solve the above technical problem, the technical solution adopted by the utility model is: an electric sunshade curtain, comprising: a mounting plate, a first guide rail, a second guide rail, a driving assembly, a telescopic rod, a reel and a curtain cloth. The first guide rail and the second guide rail are arranged at an angle on the mounting plate; the telescopic rod and the reel are both arranged between the first guide rail and the second guide rail, and both ends of the telescopic rod are slidably connected to the first guide rail and the second guide rail respectively, and both ends of the reel are rotatably connected to the first guide rail and the second guide rail respectively; wherein, the driving assembly drives the telescopic rod to slide on the first guide rail and the second guide rail to approach or move away from the reel; the curtain cloth is wound around the reel, and one end of the curtain cloth is connected to the reel, and the other end of the curtain cloth is connected to the telescopic rod.

[0007] In the above technical solution of the present utility model, aiming at the problem that the existing electric sunshade curtain structure cannot drive the opening and closing of the special-shaped curtain cloth with an asymmetric structure well, the present utility model designs a new electric sunshade curtain. The electric sunshade curtain is designed and adopts a telescopic rod to drive the special-shaped curtain cloth to open or close, that is, the above-mentioned driving component drives the telescopic rod to slide on the asymmetrically arranged first guide rail and second guide rail to approach or move away from the reel, so as to ensure that the special-shaped curtain cloth wound around the reel can be stably driven to open or close.

[0008] The reason for setting the telescopic rod is that: the telescopic rod has the function of extending or shortening the size in its own length direction, so as to slide stably on the asymmetrically arranged first guide rail and second guide rail. Among them, when the distance between the first guide rail and the second guide rail shrinks, the above-mentioned telescopic rod can retract; when the distance between the first guide rail and the second guide rail increases, the above-mentioned telescopic rod can extend, which can ensure the stability of its own movement, so as to ensure that the special-shaped curtain cloth connected to it can be smoothly opened and adapted to cover various shapes and various visible areas of the existing glass.

[0009] That is to say, by using the electric sunshade curtain designed by the present utility model, the problem that the extension directions of the first guide rail and the second guide rail are inconsistent due to the special-shaped visible area, which affects the subsequent opening or closing of the curtain cloth, can be greatly overcome. The telescopic rod can utilize its own telescopic property to achieve a steady slide on the asymmetrically arranged first guide rail and second guide rail, thereby driving the curtain cloth to close or open, improving the reliability and stability when the curtain cloth is opened or closed, ensuring that the special-shaped curtain cloth can be smoothly opened, and completely covering the special-shaped visible area of the existing glass, which has good promotion prospects and application value.

[0010] Furthermore, in the electric sunshade curtain described in the present utility model, a first guide groove extending along the length direction of the first guide rail is provided on the first guide rail, and a second guide groove extending along the length direction of the second guide rail is provided on the second guide rail; wherein, sliders are respectively connected to both ends of the telescopic rod, and the sliders are slidably arranged in the first guide groove and the second guide groove.

[0011] Furthermore, in the electric sunshade curtain described in the present utility model, the driving component is respectively connected to the sliders connected to both ends of the telescopic rod to drive the sliders to slide on the first guide rail and the second guide rail.

[0012] In the above technical solution of the present utility model, in actual application, in order to improve the sliding effect of the telescopic rod on the first guide rail and the second guide rail and improve the stability during sliding, guide grooves can also be provided on the above-mentioned first guide rail and second guide rail, and slidable sliders are provided in the guide grooves. At the same time, the two ends of the telescopic rod are respectively controlled to be connected to the sliders in the guide grooves of the first guide rail and the second guide rail, so as to realize the slidable connection between the telescopic rod and the first guide rail and the second guide rail.

[0013] Accordingly, in order to ensure that the driving force of the driving component can effectively drive the above-mentioned telescopic rod to slide on the first guide rail and the second guide rail to approach or move away from the reel, it is also possible to specifically control the driving component to be respectively connected to the sliders connected to both ends of the telescopic rod, so as to drive the telescopic rod to move by driving the movement of the sliders in the chute.

[0014] Furthermore, in the electric sunshade curtain of the present invention, the driving component includes: a motor, a first driving rod and a second driving rod. One end of the first driving rod is connected to one end of the telescopic rod, and one end of the second driving rod is connected to the other end of the telescopic rod. Moreover, the other ends of the first driving rod and the second driving rod are both in transmission connection with the output shaft of the motor.

[0015] Furthermore, in the electric sunshade curtain of the present invention, the driving component further includes: a first transmission gear, a second transmission gear and a third transmission gear. The third transmission gear meshes with the first transmission gear and the second transmission gear respectively; wherein, the output shaft of the motor is connected to the third transmission gear, the first driving rod meshes with the first transmission gear, and the second driving rod meshes with the second transmission gear.

[0016] In the above technical solution of the present invention, the driving component is an important component of the electric sunshade curtain. In order to ensure that the driving force output by the driving component can enable the telescopic rod to stably approach or move away from the reel and realize the control of the running speeds at both ends of the asymmetric guide rails, in actual application, the above gear set, namely the first transmission gear, the second transmission gear and the third transmission gear, can be set, so as to realize the steady running of the telescopic rod through the meshing and matching relationship of these three gears, thereby steadily opening the above curtain.

[0017] It should be noted that in actual application, the operator can specifically set the gear ratio relationship of the above first transmission gear, second transmission gear and third transmission gear to control the running speeds of both ends of the telescopic rod on the two asymmetric guide rails.

[0018] Furthermore, in the electric sunshade curtain of the present invention, both the first driving rod and the second driving rod are flexible soft rods.

[0019] Furthermore, in the electric sunshade curtain of the present invention, the telescopic rod includes a first cross bar, a second cross bar and a spring. The two ends of the spring respectively abut against the first cross bar and the second cross bar.

[0020] Further, in the electric sunshade curtain of the present utility model, a receiving cavity is provided in the first cross bar. An opening is formed on one side of the receiving cavity.

[0045] To describe in detail the technical content, achieved purpose and effect of the present utility model, the following is described in conjunction with the implementation modes and with reference to the drawings.

[0046] Please refer to Figures 1 to 8 shown in the figure. The present utility model designs an electric sunshade curtain, which includes: a mounting plate 1 and a first guide rail 2 and a second guide rail 3 arranged on the mounting plate 1; wherein, the above - mentioned first guide rail 2 and the second guide rail 3 are two non - symmetrically arranged guide rails, and the two are arranged at an angle on the mounting plate 1. The extending direction of the above - mentioned first guide rail 2 has an angle with both the horizontal width direction of the mounting plate 1 (i.e., Figure 1 the Y - direction shown in the figure) and the horizontal length direction of the mounting plate 1 (i.e., Figure 1 the X - direction shown in the figure), while the above - mentioned second guide rail 3 is along the horizontal width direction of the mounting plate 1 (i.e., Figure 1extends in the Y direction as shown.

[0047] In actual application, the reason for setting the above-mentioned first guide rail 2 and second guide rail 3 asymmetrically is that the curtain cloth 5 to be driven and opened by this electric sunshade is a special-shaped curtain cloth, and it applies a curtain cloth 5 with an asymmetric structure. Therefore, in order to stably drive the opening or closing of the special-shaped curtain cloth 5 with an asymmetric structure, the electric sunshade asymmetrically arranges the first guide rail 2 and the second guide rail 3 for movement guidance.

[0048] Of course, it should be pointed out that the specific shape of the curtain cloth 5 is designed according to the actual product. In some other embodiments, the curtain cloth 5 to be driven and opened by this electric sunshade can also be a curtain cloth 5 with a conventional symmetric structure, and the above-mentioned first guide rail 2 and second guide rail 3 can also be set to "be symmetrically arranged on the mounting plate 1 with each other" according to specific usage requirements to match the requirements of the curtain cloth 5; among them, the above-mentioned mounting plate 1 can specifically be the front windshield, side window, rear windshield and skylight of a vehicle, and its material can be selected as inorganic glass, plastic glass or other types of glass according to different usage positions.

[0049] Refer to Figure 1 、 Figure 4 As shown, in the present utility model, this electric sunshade further includes a driving assembly, a telescopic rod, a reel 4 and a curtain cloth 5; wherein, the above-mentioned telescopic rod and reel 4 are both arranged between the first guide rail 2 and the second guide rail 3, and both ends of the telescopic rod are slidably connected to the first guide rail 2 and the second guide rail 3 respectively, both ends of the above-mentioned reel 4 are rotatably connected to the first guide rail 2 and the second guide rail 3 respectively, and the curtain cloth 5 is wound around the reel 4, one end of the curtain cloth 5 is connected to the reel 4, and the other end of the curtain cloth 5 is connected to the telescopic rod.

[0050] In actual application, the above-mentioned driving assembly can drive the above-mentioned telescopic rod to slide on the first guide rail 2 and the second guide rail 3 to approach or move away from the reel 4, thereby driving the curtain cloth 5 to close or open, ensuring that the special-shaped curtain cloth 5 can be smoothly opened, so that the special-shaped curtain cloth 5 can be smoothly opened and adapted to cover the special-shaped visible area 101.

[0051] It should be pointed out that the reason for setting the telescopic rod is that: the telescopic rod has the ability to extend or shorten the dimension in its own length direction, and it can be adapted to be applied between the first guide rail 2 and the second guide rail 3 arranged at an angle, so as to slide stably on the first guide rail 2 and the second guide rail 3 with an asymmetric structure. Among them, when the distance between the first guide rail 2 and the second guide rail 3 shrinks, the above-mentioned telescopic rod can retract; when the distance between the first guide rail 2 and the second guide rail 3 increases, the above-mentioned telescopic rod can extend, which can ensure the stability of its own movement, thereby ensuring that the curtain cloth 5 connected thereto can be smoothly opened and adapted to cover the special-shaped visible area 101.

[0052] In the present utility model, the telescopic rod of the electric sunshade curtain may specifically include: a first cross bar 8, a second cross bar 7, and a spring 9. A receiving cavity is provided in the first cross bar 8, and an opening is formed on one side of the receiving cavity. The spring 9 is disposed in the receiving cavity, and at least a part of the second cross bar 7 extends into the receiving cavity from the opening. Wherein, one end of the spring 9 abuts against the inner wall of the receiving cavity, and the other end of the spring 9 abuts against one end of the second cross bar 7 extending into the receiving cavity, and the first cross bar 8, the second cross bar 7, and the spring 9 all extend along the horizontal length direction of the mounting plate 1 (i.e., Figure 1 the X direction shown).

[0053] For the convenience of understanding, the present utility model also provides Figure 3 and Figure 6 the sectional views shown. In the Figure 3 state shown, the telescopic rod moves to the minimum distance between the first guide rail 2 and the second guide rail 3. At this time, the curtain cloth 5 is in the "fully opened" state, and it completely shields the special-shaped visible area 101. Wherein, Figure 3 the spring 9 disposed in the receiving cavity of the first cross bar 8 is in a compressed state, and most of the second cross bar 7 extends into the receiving cavity of the first cross bar 8, so that the length dimension of the telescopic rod shrinks; correspondingly, in the Figure 6 state shown, the telescopic rod moves to the middle distance between the first guide rail 2 and the second guide rail 3. At this time, the curtain cloth 5 is in the "partially opened" state, and it does not completely shield the special-shaped visible area 101. At this time, Figure 6 the spring 9 disposed in the receiving cavity of the first cross bar 8 is in a restored state, and the dimension of the second cross bar 7 extending into the receiving cavity of the first cross bar 8 is limited, so that the length dimension of the telescopic rod is greater than the above-mentioned Figure 3 length dimension at that time.

[0054] That is to say, for the electric sunshade curtain designed by the present utility model, by setting and adopting the telescopic rod, the problem that the extending directions of the first guide rail 2 and the second guide rail 3 are inconsistent due to the special-shaped visible area 101, which affects the subsequent opening or closing of the curtain cloth 5, can be greatly overcome. The telescopic rod can utilize its own telescopic property to ensure that when driven by the driving component, it can steadily slide on the first guide rail 2 and the second guide rail 3 and approach or move away from the reel 4, thereby driving the curtain cloth 5 to close or open, and improving the reliability and stability when the curtain cloth 5 is opened or closed.

[0055] In addition, referring to Figure 2 and Figure 5As shown, in the present utility model, during actual application, in order to improve the sliding effect of the telescopic rod on the first guide rail 2 and the second guide rail 3 and enhance the stability during sliding, a first guide groove 201 extending along its own length direction can be provided on the above-mentioned first guide rail 2, a second guide groove 301 extending along its own length direction can be provided on the second guide rail 3, and a slidable slider 6 can be provided in the first guide groove 201 and the second guide groove 301. At the same time, both ends of the telescopic rod are respectively connected to the sliders 6 in the guide grooves of the first guide rail 2 and the second guide rail 3, realizing the slidable connection between the telescopic rod and the first guide rail 2 and the second guide rail 3.

[0056] Correspondingly, in order to ensure that the driving force of the driving assembly can effectively drive the above-mentioned telescopic rod to slide on the first guide rail 2 and the second guide rail 3 to approach or move away from the reel 4, it can also be specifically controlled that the driving assembly is respectively connected to the sliders 6 connected to both ends of the telescopic rod, so as to drive the sliders 6 to slide in the first guide groove 201 and the second guide groove 301, thereby further driving the telescopic rod to slide on the first guide rail 2 and the second guide rail 3.

[0057] In addition, it should be emphasized that the driving assembly is an important component of this electric sunshade curtain. The driving force output by the driving assembly can directly affect the moving speed of both ends of the telescopic rod, and it is directly related to the stability and reliability of the sliding of the telescopic rod.

[0058] In the present utility model, the designed driving assembly specifically includes: a motor, a first driving rod 10, and a second driving rod 11. One ends of the above-mentioned first driving rod 10 and second driving rod 11 are respectively connected to the sliders 6 connected to both ends of the telescopic rod, and the other ends of the above-mentioned first driving rod 10 and second driving rod 11 are in transmission connection with the output shaft of the motor through a transmission assembly 12.

[0059] It should be noted that in this driving assembly, the transmission assembly 12 is specifically provided with a gear set to realize the control of the running speeds at both ends of the asymmetric guide rail, so that the telescopic rod can stably approach or move away from the reel 4.

[0060] As Figure 4 、 Figure 7 and Figure 8 ,

[21] ]As shown, in the electric sunshade curtain of the present utility model, the transmission assembly 12 includes: a first transmission gear 121, a second transmission gear 122, and a third transmission gear 123. The above-mentioned third transmission gear 123 is respectively meshed with the first transmission gear 121 and the second transmission gear 122; among them, the output shaft of the motor is connected to the third transmission gear 123, the first driving rod 10 is meshed with the above-mentioned first transmission gear 121, and the second driving rod 11 is meshed with the above-mentioned second transmission gear 122.

[0061] In the above technical solution of the present utility model, by providing the above gear set, namely the first transmission gear 121, the second transmission gear 122 and the third transmission gear 123, using the meshing matching relationship of these three gears, an operator can change the gear ratio relationship of the first transmission gear 121, the second transmission gear 122 and the third transmission gear 123 to control the running speeds of both ends of the telescopic rod on two asymmetric guide rails.

[0062] It should be noted that in the present utility model, in order to ensure the reliability of the first driving rod 10 and the second driving rod 11 during use, an operator can specifically select the first driving rod 10 and the second driving rod 11 as flexible soft rods.

[0063] As can be seen from the above, the electric sunshade designed by the present utility model can realize the electric drive of the special-shaped curtain cloth 5, so that the special-shaped curtain cloth 5 can be smoothly opened and adapted to cover various shapes and various visible areas of the existing glass. At the same time, the electric sunshade is provided with a driving assembly and the setting of the driving assembly is optimized, so that the driving assembly can control the running speeds of both ends of the symmetric guide rails (the first guide rail 2 and the second guide rail 3), thereby realizing the steady running of the telescopic rod in the running direction to steadily open or close the curtain cloth 5. It is stable and reliable, has a good use effect, and has good promotion and application prospects.

[0064] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the related technical fields, shall be similarly included in the patent protection scope of the present utility model.
