[0044] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the following further elaborates how the present invention is implemented in combination with specific implementation manners

[0045] In a specific embodiment, the present invention provides a vehicle sun protection device. Referring to Figure 1 As shown, the vehicle sun protection device includes a plurality of roller blind assemblies 10. Each roller blind assembly 10 includes a roller blind 1, a frame 2 and a drum 3. The frame 2 is an elastic metal strip or plastic strip, and the frame 2 has a concave cross-section and is fixedly installed on the back or in the interlayer of the roller blind 1. A plurality of frames 2 are parallel to each other. In the storage state, the frame 2 and the roller blind 1 are integrally wound and stored in the drum 3. In the use state, the frame 2 and the roller blind 1 extend outwards through the opening on the drum 3

[0046] Furthermore, a tubular motor 4 is provided at the center of the drum 3 of each roller blind assembly 10 for controlling the winding and extension of the frame 2 and the roller blind 1 by rotating in the forward and reverse directions. And a control switch corresponding to each roller blind assembly 10 is provided on the vehicle cab and / or the vehicle key. A hand crank 5 is also provided on the side of the drum 3 for manually controlling the winding and extension of the frame 2 and the roller blind 1. And an operating part 9 is provided at the outer end of the frame 2 and the roller blind 1. In the storage state, the operating part 9 is located outside the opening of the drum 3 and cannot pass through the opening. The operating part 9 is used for the operator to manually pull out or push in the frame 2 and the roller blind 1

[0047] It is understandable that the rolling curtain 1, the skeleton 2, the tubular motor 4 and the hand rocker 5 can usually be hidden inside the housing of the reel 3. The operating part 9 can be a thickened structure formed by winding and sewing and shaping the rolling curtain 1 at the outer end, so that it cannot enter the opening of the reel 3. Under normal circumstances, the driver can control the winding and extension of the rolling curtain assembly 10 through the control switch, or directly manually pull out or push in the skeleton 2 and the rolling curtain 1 through the operating part 9; in special cases, the outer cover on the side of the reel 3 can be opened ( Figure 1 In order to show the internal structure of the reel, the outer cover on the side of the reel 3 is not drawn) and then manually operate the hand rocker 5 for control.

[0048] In addition, the skeleton 2 can adopt materials and shapes similar to those of existing steel tape measures. It has a concave cross-section, so that while it can be wound, it is not easy to deform under the action of internal stress after extension, thus maintaining the shapes of the skeleton 2 and the rolling curtain 1. The rolling curtain 1 can be made of materials that are soft, breathable, and have good light-shielding and wear-resistant properties, such as polyester, nylon, etc.

[0049] The vehicle sunshade device provided by the present invention uses multiple rolling curtain assemblies 10 in cooperation, optimizing the traditional vehicle sunshade equipment. It can not only effectively play a sunshade role, but also is convenient to operate and occupies a small space in the retracted state.

[0050] Further referring to Figure 2 As shown, among the multiple rolling curtain assemblies 10, there is a first inner vehicle lower curtain assembly 11. The reel 3 of the first inner vehicle lower curtain assembly 11 is fixedly installed above the dashboard area 7 of the vehicle cab. In the use state, the skeleton 2 and the rolling curtain 1 of the first inner vehicle lower curtain assembly 11 extend obliquely upward, so that the outer ends of the skeleton 2 and the rolling curtain 1 are located above the steering wheel 8.

[0051] Preferably, among the multiple rolling curtain assemblies 10, there is also a second inner vehicle lower curtain assembly; the reel 3 of the second inner vehicle lower curtain assembly is fixedly installed above the storage box area of the vehicle co-driver's cab; in the use state, the extending angle and the maximum outer end height of the skeleton 2 of the second inner vehicle lower curtain assembly are the same as those of the first inner vehicle lower curtain assembly 11.

[0052] In addition, as Figure 1 shown, for the first inner vehicle lower curtain assembly 11 and the second inner vehicle lower curtain assembly, the number of the skeletons 2 can be two and they are located at both ends, so that there is no skeleton 2 in the middle, and only the soft rolling curtain 1 and the operating part 9 exist. In this way, the first inner vehicle lower curtain assembly 11 and the second inner vehicle lower curtain assembly have the function of assisting safety. If the vehicle is bumped or brakes suddenly due to other reasons, the rolling curtain 1 and the operating part 9 can slow down the impact on the human body, and cooperate with the existing seat belts and airbags, which is equivalent to adding an extra layer of safety protection.

[0053] Preferably, the multiple rolling curtain assemblies 10 further include two in-vehicle upper curtain assemblies 12; the drums 3 of the two in-vehicle upper curtain assemblies 12 are respectively fixedly installed in the vehicle cab and the co-driver's cab, and are both located at the position near the windshield at the top inside the vehicle; in the use state, the frameworks 2 of the two in-vehicle upper curtain assemblies 12 and the rolling curtains 1 extend obliquely downward along the windshield to block a partial area of the windshield.

[0054] Preferably, the multiple rolling curtain assemblies 10 further include multiple in-vehicle side curtain assemblies (not shown in the figure); the drums 3 of the multiple in-vehicle side curtain assemblies are respectively fixedly installed at positions above or below the in-vehicle side windows; in the use state, the frameworks 2 of the in-vehicle side curtain assemblies and the rolling curtains 1 extend along the side windows to block a partial area of the side windows. The in-vehicle side curtain assemblies can all be installed above the in-vehicle side windows or all be installed below the in-vehicle side windows. Additionally, the in-vehicle side curtain assemblies can also be installed both above and below the in-vehicle side windows, and when in use, the upper and lower in-vehicle side curtain assemblies work simultaneously to block sunlight from the upper and lower directions respectively.

[0055] For the foregoing multiple types of rolling curtain assemblies 10 arranged inside the vehicle, the present invention optimizes the positions and working angles of the rolling curtain assemblies 10, which is beneficial to achieving a better sunshade effect as much as possible without affecting the driver's driving operation line of sight. As Figure 2 shown, the dotted lines in the figure represent the line-of-sight blocking angles of the first in-vehicle lower curtain assembly 11 and the in-vehicle upper curtain assembly 12 in the cab. It can be seen that the blocking angle is very small and will not affect the driver's view of the road ahead; at the same time, when the driver is driving, the driver views the dashboard area 7 through the space inside the steering wheel 8, and the first in-vehicle lower curtain assembly 11 will not have any impact on this either.

[0056] In addition, when the vehicle is in the startup state, the working ranges of the multiple types of rolling curtain assemblies 10 inside the vehicle can be restricted in advance, and the strokes of the tubular motors 4 of each rolling curtain assembly 10 can be restricted; that is, the driver can at most operate (either manually or through a control switch) the frameworks 2 and the rolling curtains 1 of the rolling curtain assembly 10 to extend a certain length. Once the preset length is reached, the corresponding tubular motor 4 is automatically locked, and its rotating shaft cannot continue to rotate in the extending direction, thereby preventing the framework 2 and the rolling curtain 1 from continuing to extend, so as to avoid blocking the line of sight and affecting driving due to misoperation; when the vehicle is in the shutdown state, the driver can operate the frameworks 2 and the rolling curtains 1 of the rolling curtain assembly 10 to extend a longer length to increase the coverage range.

[0057] Preferably, with further reference to Figure 3 and Figure 4As shown, among the multiple rolling curtain assemblies 10, there are also two roof rolling curtain assemblies 13; the drums 3 of the two roof rolling curtain assemblies 13 are respectively fixedly installed on the left and right sides of the roof; in the use state, the frame 2 of the left roof rolling curtain assembly 13 and the rolling curtain 1 extend obliquely upward to the right, and the frame 2 of the right roof rolling curtain assembly 13 and the rolling curtain 1 extend obliquely upward to the left to jointly cover the roof, and at the same time form a triangular ventilation opening below to better achieve heat dissipation.

[0058] Preferably, among the multiple rolling curtain assemblies 10, there are also two outer vehicle side curtain assemblies 14; the drums 3 of the two outer vehicle side curtain assemblies 14 are respectively installed on the left and right sides of the roof and are respectively located outside the drums 3 of the two roof rolling curtain assemblies 13; in the use state, the frame 2 of the outer vehicle side curtain assembly 14 and the rolling curtain 1 extend obliquely downward to cover a partial area of the outer side of the vehicle.

[0059] The control switch of the outer vehicle side curtain assembly 14 can be configured to be only usable when the vehicle is turned off, and at the same time, the corresponding tubular motor 4 can be automatically locked in the vehicle startup state, and its rotating shaft cannot rotate, so that the frame 2 and the rolling curtain 1 cannot extend.

[0060] Further referring to Figure 5 As shown, preferably, for any one of the outer vehicle side curtain assemblies 14, its drum 3 is integrally installed on the adjusting frame 6, the adjusting frame 6 is fixedly installed on the roof, and a control switch corresponding to the adjusting frame 6 is provided on the vehicle cab and / or the vehicle key; the adjusting frame 6 can control the corresponding drum 3 to rotate integrally within a preset range, thereby adjusting the angle between the frame 2 and the rolling curtain 1 of the outer vehicle side curtain assembly 14; for example, it is adjusted within the range from when the frame 2 is close to the vehicle side to when the frame 2 is at an obliquely upward angle.

[0061] Through such a setting, the angle between the frame 2 and the rolling curtain 1 of the outer vehicle side curtain assembly 14 can be adjusted as needed to avoid affecting the opening and closing of the vehicle door. In addition, on rainy days, when the driver and passengers get in and out of the vehicle, it is not convenient to operate the umbrella, resulting in being inevitably drenched by the rain; by using the outer vehicle side curtain assembly 14 provided by the present invention, on rainy days, the rolling curtain 1 and the frame of the side curtain assembly 14 can be first adjusted to the horizontal direction or an obliquely upward angle. In this way, when the driver and passengers need to get in and out of the vehicle at the vehicle door, the rolling curtain 1 can play a role in shielding the rain to a certain extent, facilitating the driver and passengers to open / close the umbrella and preventing them from being drenched during this process.

[0062] In addition, it can be understood that the control switches of each rolling curtain assembly 10 and the adjusting frame 6 can be connected to the vehicle wireless module, so that the driver can also remotely control each rolling curtain assembly 10 through the smartphone app.

[0063] Preferably, the plurality of rolling curtain assemblies 10 further include a front curtain assembly 15 and a rear curtain assembly 16; the drums 3 of the front curtain assembly 15 and the rear curtain assembly 16 are respectively installed on the front and rear sides of the vehicle roof; in the use state, the skeletons 2 and the rolling curtains 1 of the front curtain assembly 15 and the rear curtain assembly 16 extend obliquely downward to shield partial areas of the front and rear windshields of the vehicle.

[0064] The control switches of the front curtain assembly 15 and the rear curtain assembly 16 can be configured to be usable only when the vehicle is turned off, and at the same time, the corresponding tubular motors 4 can be automatically locked when the vehicle is in the starting state, and their rotating shafts cannot rotate, so that the skeletons 2 and the rolling curtains 1 cannot extend.

[0065] Furthermore, the cross-sectional shapes of the drums 3 of the front curtain assembly 15 and the rear curtain assembly 16 can be configured to be streamlined to reduce the wind resistance during vehicle driving.

[0066] In addition, the drum 3 of each illustrated rolling curtain assembly 10 is exposed outside the vehicle body, which is convenient for installation on the vehicle; in other embodiments, the rolling curtain assembly 10 can also be pre-configured during vehicle manufacturing, so that the drum 3 is hidden and installed inside the vehicle body, and only the opening of the drum 3 is reserved on the vehicle body surface, and only the operation part 9 at the outer end of the rolling curtain 1 is located outside the opening in the storage state.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
