[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0031] See the figure below for reference Figure 1-Figure 5 A sunshade device 100 according to an embodiment of the present invention is described, and the sunshade device 100 can be applied to a vehicle.
[0032] Combination Figure 1-Figure 5As shown, the sunshade device 100 according to the embodiment of the utility model can mainly include: a housing 10, a sunshade curtain 20, a lifting assembly 30 and a driving member 60, wherein a reel 11 is arranged in the housing 10, and the sunshade curtain 20 is wound around the reel 11 and selectively extends from the housing 10 to provide sunshade. Specifically, the housing 10 can provide a setting space for the reel 11 in the sunshade device 100, and the reel 11 can be fixed in the housing 10 to prevent the reel 11 from rolling. The sunshade curtain 20 is wound on the reel 11, which makes it easy to store the sunshade curtain 20. When the passengers in the vehicle do not need to use the sunshade curtain 20, the sunshade curtain 20 can be wound on the reel 11 to store the sunshade curtain 20, so that the sunshade curtain 20 will not only not block the sight of the passengers in the vehicle, but also reduce the space occupied by the sunshade curtain 20 in the vehicle.
[0033] In practical applications, the sunshade device 100 is usually arranged inside the vehicle door, so that the space occupied by the sunshade curtain 20 inside the vehicle door when it is stored can be reduced to prevent the sunshade device 100 from occupying too much space inside the passenger compartment, thereby ensuring that the space size of the passenger compartment meets the use needs of passengers, which is conducive to improving the riding comfort. It should be noted that the unfolded shape of the sunshade curtain 20 after extending from the shell 10 can be set according to the window shape of different vehicle models, so that the sunshade device 100 in the embodiment of the utility model is suitable for more vehicle models.
[0034] Furthermore, the lifting assembly 30 includes a lifting rod 31 and a pull wire 32. The upper end of the lifting rod 31 extends into the housing 10 and is connected to the sunshade 20, so that the lifting rod 31 and the upper end of the sunshade 20 can be transmitted. When the lifting rod 31 rises, it can drive the upper end of the sunshade 20 to rise. At this time, the reel 11 rotates so that the sunshade 20 extends from the housing 10 and unfolds. In this way, the sunshade 20 can partially or completely block the car window, which can be used to reduce sunlight outside the car, or can be used to block privacy inside the car. When the lifting rod 31 descends, the lifting rod 31 can drive the upper end of the sunshade 20 to descend, and the roller curtain is rewound on the reel 11, so that the sunshade 20 is retracted from the outside of the housing 10 to the inside of the housing 10, which not only makes the view inside the car not blocked, but also can store the sunshade 20.
[0035] Further, the pull wire 32 includes a first pull wire 321 and a second pull wire 322, and the upper end of the first pull wire 321 and the upper end of the second pull wire 322 are both connected to the lifting rod 31, so that the first pull wire 321 and the second pull wire 322 can be transmission-connected to the lifting rod 31. The driving member 60 is respectively connected to the lower ends of the first pull wire 321 and the second pull wire 322, so that the driving member 60 can be transmission-connected to the first pull wire 321 and the second pull wire 322. In this way, the output power of the driving member 60 can be transmitted to the lifting rod 31 through the first pull wire 321 and the second pull wire 322, and the lifting rod 31 can be driven to rise and fall.
[0036] Furthermore, the driving member 60 retracts and releases the first pull wire 321 and the second pull wire 322, which can not only drive the lifting rod 31 to rise and fall to selectively drive the sunshade 20 to extend from the outer shell 10, but also prevent the lower ends of the first pull wire 321 and the second pull wire 322 from being too long, thereby reducing the structural space of the sunshade device 100 in the vehicle, and can reduce the guide structure provided for accommodating the lower ends of the first pull wire 321 and the second pull wire 322. In this way, the sunshade device 100 can be prevented from occupying too much space in the vehicle door, which not only makes it convenient to provide a glove box with a larger accommodating space on the vehicle door, but also helps to increase the space of the passenger compartment in the vehicle, thereby ensuring the comfort of the passengers in the vehicle.
[0037] Compared with the prior art, the structure of the sunshade device 100 in the embodiment of the utility model is more compact and can be arranged on more vehicle models. In addition, the lower ends of the first pull wire 321 and the second pull wire 322 are both connected to the driving member 60, which can reduce the arrangement of parts such as the cable guide sleeve, which is conducive to reducing the parts of the sunshade device 100, and further can reduce the manufacturing cost of the sunshade device 100.
[0038] Combination Figure 3 and Figure 5 As shown, the sunshade device 100 further includes a wire wheel 40, a driving member 60 is transmission-connected to the wire wheel 40, and a first pull wire 321 and a second pull wire 322 are wound around the wire wheel 40. Specifically, the driving member 60 is directly transmission-connected to the wire wheel 40, which can reduce the power loss in the transmission process, thereby improving the operation efficiency of the sunshade device 100, and can reduce the arrangement of transmission members such as gears in the prior art, simplify the drive structure of the sunshade device 100, and save manufacturing costs.
[0039] Furthermore, the lower ends of the first and second cables 321 and 322 are both wound around the wire wheel 40, so that when the driving member 60 drives the wire wheel 40 to rotate, the first and second cables 321 and 322 can be retracted. In this way, not only can the first and second cables 321 and 322 drive the driving rod to rise and fall, but also the lower ends of the first and second cables 321 and 322 can be retracted, which can prevent the lower ends of the first and second cables 321 and 322 from being too long and wound, thereby ensuring the smooth operation of the sunshade device 100.
[0040] Combination Figure 5 As shown, the first cable 321 and the second cable 322 are wound in opposite directions on the wire wheel 40. Specifically, the winding directions of the first cable 321 and the second cable 322 on the wire wheel 40 are opposite, that is, the first cable 321 and the second cable 322 extend from opposite ends of the wire wheel 40 in the diameter direction, and the upper ends are connected to the slider 33. In this way, when the wire wheel 40 rotates in either clockwise or counterclockwise direction, the length of the part of the first cable 321 and the length of the part of the second cable 322 between the slider 33 and the wire wheel 40 are the same, so that the stability of the slider 33 when moving up and down can be ensured.
[0041] When the wire wheel 40 rotates in one direction, clockwise or counterclockwise, one of the first pull wire 321 and the second pull wire 322 is shortened and the other is extended. When the wire wheel 40 rotates in the other direction, clockwise or counterclockwise, one of the first pull wire 321 and the second pull wire 322 is extended and the other is shortened. Thus, the lifting member can be driven to move in different directions.
[0042] Combination Figure 4 As shown, the lifting assembly 30 also includes a slider 33, which is connected to the lower end of the lifting rod 31 and can slide up and down, and the upper ends of the first pull wire 321 and the second pull wire 322 are connected to the slider 33. In this way, when the wire wheel 40 rotates to retract and release the first pull wire 321 and the second pull wire 322, the first pull wire 321 and the second pull wire 322 can simultaneously drive the slider 33 to slide up and down, so that the retracting and releasing movement of the first pull wire 321 and the second pull wire 322 can be converted into the up and down movement of the slider 33, so that the lifting rod 31 can be subjected to an upward or downward pulling force, and the reliability and stability of the lifting of the lifting rod 31 can be ensured.
[0043] Combination Figure 4As shown, the upper end of the first pull wire 321 is connected to the lower side of the slider 33, and the upper end of the second pull wire 322 passes through the slider 33 and is connected to the upper side of the slider 33. In this way, the first pull wire 321 can apply tension to the lower side of the slider 33, and the second pull wire 322 can apply tension to the upper side of the slider 33. Specifically, when the wire wheel 40 rotates in one of the clockwise and counterclockwise directions, if the first pull wire 321 is shortened, the length of the first pull wire 321 outside the wire wheel 40 is shortened, so the first pull wire 321 can provide a tension to the lower side of the slider 33, and the second pull wire 322 is lengthened at this time, and the second pull wire 322 will not apply tension to the upper side of the slider 33, and the first pull wire 321 can drive the slider 33 to move.
[0044] Furthermore, when the wire wheel 40 rotates in the other direction of clockwise and counterclockwise, if the second pull wire 322 is shortened, the length of the second pull wire 322 outside the wire wheel 40 is shortened, so the second pull wire 322 can provide a pulling force on the upper side of the slider 33. At this time, the first pull wire 321 is lengthened, and the first pull wire 321 will not apply a pulling force to the lower side of the slider 33, and the second pull wire 322 can drive the slider 33 to move.
[0045] Combination Figure 1-Figure 5 As shown, the lifting assembly 30 also includes a shell 34, the slider 33 and the pull wire 32 are both arranged in the shell 34, and the shell 34 is provided with a fixed pulley 50 above the corresponding slider 33. The upper end of the second pull wire 322 passes through the slider 33 and is U-shaped. The top of the upper end of the second pull wire 322 passes through the slider 33 and is located on the upper side of the fixed pulley 50, and is limitedly matched with the fixed pulley 50.
[0046] Specifically, the housing 34 can provide a setting position for the slider 33 and the cable 32, and can ensure the structural reliability of the slider 33 and the cable 32 in the vehicle. A fixed pulley 50 is arranged on the top of the housing 34, wherein the upper end of the second cable 322 bypasses the fixed pulley 50 and is connected to the upper side of the slider 33. In addition, the upper end of the second cable 322 passes through the fast recovery diode area of the slider 33 and is U-shaped. In this way, the fixed pulley 50 can not only ensure that the force on the second cable 322 between the wire wheel 40 and the fixed pulley 50 is the same as the force on the second cable 322 between the fixed pulley 50 and the slider 33, but also make the force on the second cable 322 between the wire wheel 40 and the fixed pulley 50 opposite to the force on the second cable 322 between the fixed pulley 50 and the slider 33.
[0047] In this way, when the wire wheel 40 rotates to shorten the second wire 322, the force on the second wire 322 between the wire wheel 40 and the fixed pulley 50 is directed toward the wire wheel 40, and the force on the second wire 322 between the fixed pulley 50 and the slider 33 is directed toward the fixed pulley 50. As a result, the tension generated when the second wire 322 is shortened can pull the slider 33 to move upward in the housing 34, so that the lifting rod 31 can be driven to rise, so that the lifting rod 31 drives the upper end of the sunshade 20 to move upward, so that the sunshade 20 is unfolded.
[0048] Combination Figure 4 and Figure 5 As shown, the lifting assembly 30 also includes a housing 34, a slide groove 341 is provided in the housing 34, and the slider 33 is provided in the housing 34 and slides up and down in the slide groove 341. Specifically, the housing 34 can provide a reliable setting position for the slider 33. The housing 34 is provided with a slide groove 341 extending up and down, and the slide groove 341 can limit the moving direction of the slider 33 in the housing 34, so that the slider 33 can always move in the up and down direction in the housing 34, so that the reliability of the slider 33 driving the lifting rod 31 to move up and down can be ensured. In this way, the reliability of the sunshade 20 being unfolded and retracted can be ensured.
[0049] Combination Figure 4 and Figure 5 As shown, a limit piece 342 is provided in the housing 34, the limit piece 342 extends in the up-down direction, and the limit piece 342 passes through the slider 33. Specifically, the limit piece 342 extends up and down in the housing 34, and passes through the slider 33, so that the slider 33 can play a supporting role when moving in the housing 34, and the stability of the slider 33 when moving up and down can be ensured, and the upper end of the lifting rod 31 can be prevented from tilting due to the shaking of the slider 33, so that the sunshade 20 can accurately cover the car window when it is unfolded, so as to improve the working reliability of the sunshade device 100.
[0050] Furthermore, there are at least two limiting plates 342, which are arranged at intervals, and a slide groove 341 is defined between two adjacent limiting plates 342. Such an arrangement can, on the one hand, limit the moving direction of the slider 33 in the shell 34 to ensure that the slider 33 moves up and down normally. On the other hand, multiple limiting plates 342 can increase their contact area with the slider 33, which can increase the friction between the slider 33 and the limiting plates 342, which is beneficial to improving the structural stability of the slider 33 when it moves up and down, thereby helping to improve the stability of the unfolding and folding of the sunshade 20, and can prevent the lifting rod 31 and the sunshade 20 from colliding with the door structure during movement.
[0051] Combination Figure 4 and Figure 5As shown, in the embodiment of the present utility model, there are two limit plates 342, and the two limit plates 342 define a slide groove 341, and the first pull wire 321 and the second pull wire 322 are respectively arranged at intervals on both sides of the slide groove 341. Specifically, the two limit plates 342 are provided, which can not only ensure the movement stability of the slider 33 in the housing 34, but also prevent the slider 33 from being stuck due to excessive friction, so that the slider 33 can be ensured to move smoothly in the housing 34.
[0052] Furthermore, the two limit plates 342 can not only define the slide groove 341, but also separate the first pull wire 321 and the second pull wire 322 in the shell 34, so that the first pull wire 321 and the second pull wire 322 are independently arranged in the shell 34, which can prevent the first pull wire 321 and the second pull wire 322 from being entangled with each other, and ensure the normal operation of the lifting assembly 30.
[0053] According to an embodiment of the utility model, a vehicle includes a sunshade device 100 in the utility model. The sunshade device 100 of the utility model drives the wire wheel 40 to rotate by setting a driving member 60, and the wire wheel 40 drives the slider 33 to move up and down by retracting and releasing the first pull wire 321 and the second pull wire 322, and then drives the lifting rod 31 to drive the sunshade curtain 20 to rise and fall, so as to selectively make the sunshade curtain 20 block the vehicle window. Such a setting can not only reduce the space occupied by the sunshade device 100 in the vehicle, but also simplify the structure of the sunshade device 100, simplify the drive of the sunshade device 100, and facilitate the installation of the sunshade device 100.
