Description

Technical Field

[0001] This utility model relates to the field of car sunshades, and specifically to an electric sunshade. Background Technology

[0002] A car's sunroof or panoramic sunroof is installed on the roof. When open, it facilitates air circulation inside the vehicle, increasing the intake of fresh air. Both sunroofs and panoramic sunroofs increase interior light, providing a healthy and comfortable experience for the occupants. Sunroofs also offer a wider field of vision. However, in bright sunlight or high temperatures, the sunroof or panoramic sunroof needs to be covered, i.e., equipped with a sunshade. Existing sunshades come in both manual and electric versions, but both types have some drawbacks.

[0003] Existing manual sunshades often require double horizontal beams at the front and rear to achieve double-opening functionality, and employ a pivot design at the rear, resulting in a smaller light-receiving area and insufficient headroom for rear passengers. Furthermore, the manual opening method is laborious, leading to a poor user experience. Existing electric sunshades use a motor to directly drive the roller blind shaft, requiring a larger installation space along the shaft axis, which is detrimental to the miniaturization of the overall structure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an electric sunshade curtain with the advantages of electric control, smaller space occupation, and stable and efficient curtain opening and closing.

[0005] The purpose of this utility model is achieved through the following technical solution: This electric sunshade includes a canopy, a frame assembly mounted on the canopy, and a roller shutter shaft mounted on one side of the frame assembly; The frame assembly includes a front beam and a rear beam arranged at intervals. A guide rail is provided at both ends of the front beam and the rear beam. The front end of each guide rail is fixed to the front beam by a front connector. The rear end of one guide rail is fixed to the rear beam by a first rear connector, and the rear end of the other guide rail is fixed to the rear beam by a second rear connector. The roller shutter shaft is located on the outside of the rear beam. A pull rod is slidably installed inside the frame assembly. Both ends of the pull rod are slidably mounted on the corresponding guide rails via sliders. A curtain is fixed to one side of the pull rod, and the other end of the curtain is fixed to the roller shutter shaft. A spool is installed at both ends of the roller shutter shaft, and a pull rope is wound on each spool. The pull rope passes through the first or second rear connector, runs along the corresponding guide rail, and is turned by the steering pulley on the front connector and then connected to the corresponding slider. A synchronous pulley assembly and a motor are provided on the first rear connector. The motor drives the roller shutter shaft to rotate through the synchronous pulley assembly. When the motor drives the roller shutter shaft to rotate, the curtain is rolled up on the roller shutter shaft or released from the roller shutter shaft.

[0006] As a further technical solution, the spool is mounted on the roller blind shaft via a coil spring, and a continuous tapered groove is provided along the outer wall of the spool. The pull rope is tensioned on the groove by the coil spring. A rotating shaft is also coaxially mounted on the spool, and the rotating shaft is engaged with the roller blind shaft in a slotted transmission manner.

[0007] As a further technical solution, the synchronous pulley assembly includes a housing, inside which two synchronous pulleys are installed via synchronous belt drive. One of the synchronous pulleys is driven by a motor, and the other synchronous pulley has a spindle at its center. The spindle passes through the housing and is connected to the shaft head of the rotating shaft for transmission.

[0008] As a further technical solution, a guide rail mating part is provided on one side of the slider for sliding installation on the guide rail, and a pull rod mating part is provided on the other side of the slider for insertion into the pull rod.

[0009] As a further technical solution, a rear limit switch is installed on the first rear connector and / or the second rear connector, and a front limit switch is installed on at least one front connector. Magnet mounting holes are opened at both ends of the guide rail mating part for installing magnets. The magnets cooperate with the front limit switch or the rear limit switch to detect the position of the slider.

[0010] As a further technical solution, both the front limit switch and the rear limit switch adopt Hall switches.

[0011] As a further technical solution, the motor is controlled by a control circuit board. The front limit switch and the rear limit switch are electrically connected to the control circuit board, wherein the front limit switch is used to send a signal indicating that the curtain is retracted and in place, and the rear limit switch is used to send a signal indicating that the curtain is opened and in place.

[0012] As a further technical solution, control buttons are installed on the ceiling, and the control buttons are electrically connected to the control circuit board.

[0013] The beneficial effects of this utility model are as follows: 1. The motor and the roller blind shaft are driven by a synchronous pulley assembly, which saves the installation space of the sunshade on the roller blind shaft axis and occupies less space overall; 2. The pull cord is tensioned on the groove of the pull wheel by a coil spring, which can realize the automatic opening and closing of the sunshade curtain without the need for manual opening and closing, making the operation more convenient and efficient; 3. Using synchronous belt drive, the overall space occupied is smaller and the manufacturing cost is reduced compared to gear drive; 4. Magnets are installed on both sides of the slider, which, together with the front and rear limit switches (Hall switches), can quickly and efficiently determine whether the sunshade is fully opened or closed. 5. Limit switches are electrically connected to the control circuit board for communication, enabling timely sending of position signals to control the motor to stop rotating, preventing the curtain from opening or closing excessively, ensuring overall safe and reliable operation; 6. Control buttons are integrated on the ceiling, allowing you to open or close the curtains by pressing the buttons, which is convenient and efficient. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings: Example: As attached Figures 1-10 As shown, this type of electric sunshade includes a roller shutter shaft 1, a guide rail 2, a roller 3, a roller groove 31, a rotating shaft 32, a shaft head 321, a pull rod 4, a slider 5, a guide rail mating part 51, a magnet mounting hole 511, a pull rod mating part 52, a front connector 6, a steering roller 61, a front limit switch 62, a first rear connector 7, a synchronous pulley assembly 71, a housing 711, a synchronous pulley 712, a spindle 713, a fixing plate 714, a rear limit switch 72, a motor 73, a control circuit board 74, a fixing block 75, a front beam 8, a rear beam 9, a canopy 10, a control button 11, and a second rear connector 12.

[0026] Reference Appendix Figure 1 , 2 3. For ease of illustration, the curtain is hidden in the figure and not shown. In actual use, the curtain needs to be installed on the roller blind shaft 1. The ceiling 10 is fixedly installed at the corresponding position of the sunroof inside the vehicle. A frame assembly is fixed on the ceiling 10, and the roller blind shaft 1 is installed on one side of the frame assembly.

[0027] like Figure 3 As shown, the frame assembly includes a front beam 8 and a rear beam 9 arranged at intervals (located on the left and right sides of the figure, respectively). A guide rail 2 is provided at both ends (top and bottom) of the front beam 8 and the rear beam 9. The front end of each guide rail 2 is inserted and fixed to the front beam 8 through a front connector 6. The rear end of one guide rail 2 is inserted and fixed to the rear beam 9 through a first rear connector 7, and the rear end of the other guide rail 2 is inserted and fixed to the rear beam 9 through a second rear connector 12.

[0028] Furthermore, the roller shutter shaft 1 is located on the outside of the rear beam 9 ( Figure 3On the left side), a pull rod 4 is slidably installed within the frame assembly. Both ends of the pull rod 4 are slidably mounted on the corresponding guide rails 2 via sliders 5. A curtain is fixed to one side of the pull rod 4, and the other end of the curtain is fixed to the roller blind shaft 1. A spool 3 is installed at both ends of the roller blind shaft 1. A pull cord (not shown in the figure) is wound around each spool 3. The pull cord passes through the first rear connector 7 or the second rear connector 12, runs along the corresponding guide rail 2, and is then turned and fixedly connected to the corresponding slider 5 via the steering spool 61 on the front connector 6.

[0029] Preferably, the reel 3 is mounted on the roller shutter shaft 1 via a coil spring, and a continuous, tapered groove 31 is provided along the outer wall of the reel 3. The pull rope is tensioned on the groove 31 by the coil spring. A rotating shaft 32 is also coaxially mounted on the reel 3. Figure 10 As shown, the rotating shaft 32 and the roller shutter shaft 1 are driven by a slotted connection.

[0030] Furthermore, such as Figure 9 , 10 As shown, a synchronous wheel assembly 71 and a motor 73 are provided on the first rear connector 7. The motor 73 drives the roller blind shaft 1 to rotate through the synchronous wheel assembly 71. When the motor 73 drives the roller blind shaft 1 to rotate, the curtain is rolled up on the roller blind shaft 1 or released (unrolled) from the roller blind shaft 1.

[0031] Furthermore, such as Figure 10 As shown, the synchronous pulley assembly 71 includes a housing 711, in which two synchronous pulleys 712 are installed. The two synchronous pulleys 712 are driven by a synchronous belt (not shown in the figure). One of the synchronous pulleys 712 is driven by a motor 73 (motor shaft), and the other synchronous pulley 712 has a spindle 713 at its center. The spindle 713 passes through the housing 711 and is connected to the shaft head 321 of the rotating shaft 32 by a key. A fixing plate 714 is bolted to the opening of the housing 711 for easy disassembly and assembly.

[0032] Reference Appendix Figures 5-8 A guide rail mating part 51 is provided on one side of the slider 5. The guide rail mating part 51 can be slidably mounted on the guide rail 2. A pull rod mating part 52 is provided on the other side of the slider 5. The pull rod mating part 52 is used to be inserted into the pull rod 4.

[0033] A rear limit switch 72 is mounted on the first rear connector 7 and / or the second rear connector 12 (preferably, the rear limit switch 72 is fixed to the first rear connector 7 by a fixing block 75, such as...). Figure 9 , 10 As shown), preferably, a front limit switch 62 is installed on the front limit switch 6 corresponding to the guide rail 2 on the first rear connector 7. Both the front limit switch 62 and the rear limit switch 72 are Hall switches. Figure 7 , 8As shown, a magnet mounting hole 511 is opened at both ends of the guide rail mating part 51. A magnet is installed in the magnet mounting hole 511. The position of the slider 5 is detected by the cooperation of the magnet with the front limit switch 62 or the rear limit switch 72. When the limit switch is triggered, it is determined that the slider 5 has slid into place.

[0034] A control circuit board 74 is installed inside the housing of the motor 73. The control circuit board 74 controls the operation of the motor 73 using signals. The front limit switch 62 and the rear limit switch 72 are electrically connected to the control circuit board 74, respectively. The front limit switch 62 can send a signal indicating that the curtain is fully retracted, and the rear limit switch 72 can send a signal indicating that the curtain is fully open. Preferably, a set of control buttons 11 is installed on the ceiling 10, and the control buttons 11 are electrically connected to the control circuit board 74, which facilitates the user to issue commands to open or close the curtain.

[0035] The working process of this utility model: When the curtain needs to be opened, press the control button 11 (the open button). The control circuit board 74 receives the curtain opening signal and starts the motor 73. The motor 73 drives the roller sheave 3 and the roller shutter shaft 1 to rotate synchronously through the synchronous pulley 712. The roller shutter shaft 1 gradually releases the curtain, while the pull cord is gradually drawn back onto the roller sheave groove 31. Under the action of the coil spring in the roller sheave 3 and the pull cord, the slider 5 begins to slide along the guide rail 2 (outward, i.e., away from the roller shutter shaft 1). The pull rod 4 then drives the curtain to gradually unfold along the length of the guide rail 2. When the slider 5 moves to the vicinity of the limit switch 62, the magnet at the end of the slider 5 triggers the limit switch 62. The limit switch 62 determines that the curtain is fully opened and sends an open signal to the control circuit board 74. After receiving the signal, the control circuit board 74 controls the motor 73 to stop rotating, completing the curtain opening action.

[0036] When the curtain needs to be closed (retracted), press the control button 11 (the retraction button). The control circuit board 74 receives the curtain retraction signal and controls the motor 73 to rotate in the opposite direction. The motor 73 drives the reel 3 and the roller blind shaft 1 to rotate synchronously in the opposite direction via the synchronous pulley 712. The roller blind shaft 1 gradually retracts the curtain. Driven by the curtain and the pull rod 4, the slider 5 begins to slide along the guide rail 2 (inward, i.e., towards the roller blind shaft 1), while the pull rope gradually comes out from the reel groove 31. When the slider 5 moves to the vicinity of the rear limit switch 72, the magnet at the end of the slider 5 triggers the rear limit switch 72. The rear limit switch 72 determines that the curtain is retracted in place and sends a retraction in place signal to the control circuit board 74. After receiving the signal, the control circuit board 74 controls the motor 73 to stop rotating, completing the curtain retraction action.
