[0002] Cars are one of the common means of transportation on the market. Most cars are equipped with sunroofs. Although many sunroofs can block ultraviolet rays, they still cannot change the phenomenon of heat in the car. Therefore, existing cars often install electric sunshades at the position of the sunroof; existing electric retractable curtains use a connection method in which the motor is in the middle and a transmission shaft is used on each side for transmission. One end of the sunshade is installed on the transmission belt, and the motor moves back and forth to drive the sunshade to move back and forth; however, this method in which the motor is directly installed in the middle of the transmission rod as an integral whole is prone to failure and is difficult to replace, and the motor drives two transmission shafts respectively, and the two transmission shafts are prone to left-right misalignment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a sunroof sunshade for a vehicle, which can effectively solve the problem of single function in the prior art for studying the characteristics of aurora plasma.

[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0020] like Figure 1 As shown, a preferred embodiment of the utility model provides a vehicle sunroof sunshade, which includes a frame assembly 1, a reel 2, a conveyor belt mechanism 3, a motor 4, a first rotating shaft 5, a second rotating shaft 6, a first gear 7 and a second gear 8. The conveyor belt mechanism 3 is provided with two and is respectively located on the left and right sides of the frame assembly 1. A sunshade is wound on the reel 2. The front ends of the sunshade are respectively fixedly connected to the conveyor belt mechanisms 3 located on both sides. One end of the two conveyor belt mechanisms 3 is connected through the first rotating shaft 5, and the other ends of the two conveyor belt mechanisms 3 are connected through the second rotating shaft 6. The first gear 7 is fixed on the power output end of the motor 4, and the second gear 8 is fixed on the first rotating shaft 5. The first gear 7 is meshed with the second gear 8. The motor 4 can drive the sunshade to move to cover or expose the car sunroof.

[0021] Since the first gear 7 is fixed on the power output end of the motor 4 and the second gear 8 is fixed on the first rotating shaft 5, the first gear 7 is meshed with the second gear 8. When the sunroof needs to be opened, the motor 4 rotates forward, thereby driving the first rotating shaft 5 to rotate forward so that the conveyor belt mechanism 3 drives the sunshade to open; when the sunroof needs to be closed, the motor 4 reverses, thereby driving the first rotating shaft 5 to rotate in the opposite direction so that the conveyor belt mechanism 3 drives the sunshade to close. In this solution, the motor 4 and the first rotating shaft 5 are separately arranged, and the motor 4 and the first rotating shaft 5 are connected by gears, and the movement of the sunshade is achieved by a long transmission shaft at the front and rear, and the structure is stable, the failure rate is low, and the noise is reduced.

[0022] During specific use, an infrared sensor can be installed on the reel 22. The infrared sensor is electrically connected to the motor 44. When a human body is detected, the motor 44 stops rotating, thereby avoiding pinching of human hands.

[0023] For example, Figure 2 As shown, the conveyor belt mechanism 3 includes a driving wheel, a driven wheel, a synchronous belt 301, a connecting member 302, a connecting rod 303 and a guide wheel 304. The driving wheel and the driven wheel are connected through the synchronous belt 301. The driving wheel is fixedly connected to the first rotating shaft 5, and the driven wheel is fixedly connected to the second rotating shaft 6. The front end of the sunshade is fixedly connected to the synchronous belt 301, the connecting member 302 is fixed on the synchronous belt 301, one end of the connecting rod 303 is fixedly connected to the connecting member 302, and the other end of the connecting rod 303 is fixedly connected to the guide wheel 304. Therefore, the guide wheel 304 can play a supporting role, thereby preventing the synchronous belt 301 from being loosened after being used for a long time, ensuring the smooth transmission of the synchronous belt 301, and ensuring that the sunshade is in a normal opening and closing state.

[0024] Exemplarily, the frame assembly 1 includes a front beam, a rear beam 102, two side beams 103 and a bottom plate 104. The front beam, the rear beam 102 and the side beams 103 are all fixed on the bottom plate 104. The side beams 103 are connected between the front beam and the rear beam 102. The two conveyor belt mechanisms 3 are respectively connected to the two side beams 103. In this embodiment, in order to ensure the overall rigidity of the entire frame assembly 1, the front beam, the rear beam 102 and the two side beams 103 are all set to aluminum.

[0025] Exemplarily, for the convenience of installation, both the front and rear sides of the side beam 103 are provided with mounting brackets 9 for mounting the driving wheel or the driven wheel.

[0026] For example, a switch is provided on the front beam, and the switch is electrically connected to the motor 4; a micro switch is provided on both the front beam 101 and the rear beam 102, and the micro switch is electrically connected to the motor 4. Thus, the sunshade can be opened and closed directly by the switch, which is convenient for use. In addition, when the sunshade touches the micro switch, the sunshade is opened or closed in place, and the motor 4 can automatically stop rotating, without the need to manually turn off the switch, which is convenient for use.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] 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 substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
