[0033] The following further details this application with reference to the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain this application, and should not be construed as a limitation of this application.

[0034] As Figures 1 to 3As shown in the figure, this embodiment provides a cleaning structure for a roof sunroof, including: a wiper 1, a driving device 2, and a height adjustment mechanism 3. Among them, the wiper 1 includes a bracket 11 and a wiper element 12 installed on the bracket 11 and used for sliding contact with the outer surface of the roof sunroof 5. The wiper element 12 can be one or more of a brush, a flexible wiper blade, a sponge, etc.; the driving device 2 is fixed to the roof sheet metal 4 and connected to the bracket 11 of the wiper 1, and the driving device 2 is configured to be able to drive the wiper 1 to perform a reciprocating motion along a preset trajectory on the outer surface of the roof sunroof 5; the height adjustment mechanism 3 is arranged between the bracket 11 and the connection end 21 of the driving device 2 for connecting the bracket 11, and is used to adjust the installation height of the bracket 11 relative to the connection end 21. In this way, the driving device 2 drives the wiper 1 to make sliding contact with the roof sunroof 5 to realize the cleaning operation of the outer surface of the roof sunroof 5. At the same time, the height adjustment mechanism 3 can adjust the installation height of the wiper 1, so as to adjust the scraping force of the wiper 1 relative to the outer surface of the roof sunroof 5, realize the effective cleaning of the roof sunroof 5, and solve the problem that it is difficult to clean the accumulated and adhered dirt on the roof sunroof 5.

[0035] It can be understood that the way the driving device 2 drives the wiper 1 to move can be to set the driving device 2 on one side of the roof sunroof 5 in the vehicle width direction and drive the wiper 1 to perform a linear reciprocating motion in the vehicle length direction; or the driving device 2 can be set on one side of the roof sunroof 5 in the vehicle length direction and drive the wiper 1 to perform a linear reciprocating motion in the vehicle width direction; it can also be to set the driving device 2 on any side of the roof sunroof 5 and drive the wiper 1 to perform an arc-shaped reciprocating swing along the outer surface of the roof sunroof 5; as long as it can drive the wiper 1 to perform a reciprocating motion along a preset trajectory on the outer surface of the roof sunroof 5, there is no limitation here.

[0036] For example, in some embodiments, such as Figure 1 and Figure 2As shown in the figure, the driving device 2 includes a slide rail 22, a sliding connector 23 and a driving component 24. The slide rail 22 is fixed to one side of the roof sunshade 5, preferably on the vehicle width direction side of the roof sunshade 5. One end of the sliding connector 23 is slidably connected to the slide rail 22, and the other end serves as a connection end 21 and is connected to the bracket 11. The driving component 24 is in transmission connection with the sliding connector 23 to drive the sliding connector 23 to move along the slide rail 22. In this way, by designing the trajectory of the slide rail 22, the wiper 1 can move along the slide rail 22 in a preset trajectory, and the driving component 24 only needs to drive the sliding connector 23 to move along the slide rail 22, which can effectively ensure the smooth movement and direction diversity of the wiper 1. Preferably, two sets of driving devices 2 can be provided. The two sets of driving devices 2 / 2' are respectively arranged on both sides of the roof sunshade 5 in the vehicle width direction and are parallel to each other. The wiper 1 is vertically arranged between the two sets of driving devices 2 / 2'. The two ends of the wiper 1 are respectively connected to the driving devices 2 / 2' on both sides through the brackets 11. In this way, not only can the movement stability and support strength of the wiper 1 be improved, but also the fitting degree between the two ends of the wiper 1 and the roof sunshade 5 can be improved, further enhancing the cleaning ability of the wiper 1.

[0037] Further, in this embodiment, as Figure 3 shown, the driving component 24 includes a transmission belt 241, a driving end 242 and a driven end 243. The transmission belt 241 is arranged along the slide rail 22. The driving end 242 and the driven end 243 are respectively located at both ends of the slide rail 22, and both ends of the transmission belt 241 are respectively wound around the driving end 242 and the driven end 243, so that the driving end 242 and the driven end 243 are synchronously in transmission connection. The sliding connector 23 is fixedly connected to the transmission belt 241. The specific connection method can be bonding, clamping, perforating connection or meshing connection with the transmission belt 241, etc., so that it moves along the slide rail 22 with the transmission belt 241, that is, the operation of driving the sliding connector 23 to move along the slide rail 22 is realized. It can be understood that in other embodiments, the driving component 24 can also adopt other transmission structures for transmission, such as pneumatic, electric, tooth chain structure, etc. to pull and push the sliding connector 23, and it can drive the sliding connector 23 to perform reciprocating movement along the slide rail 22.

[0038] Preferably, in this embodiment, the driving end 242 is set as a driving motor. The transmission belt 241 is wound around the acting end of the driving motor. By controlling the driving motor to rotate forward or backward, the sliding connector 23 is driven to move forward or backward along the slide rail 22. The driven end 243 is set as a driven wheel, which can reduce the number of motors set, simplify the structural layout, reduce the space occupation and the setting of waterproof and dustproof sealing. In other embodiments, a driving motor can also be provided at the driven end 243 to run synchronously with the driving motor at the driving end 242 to improve the transmission ability of the transmission belt 241.

[0039] It can be understood that the manner in which the aforementioned height adjustment mechanism 3 adjusts the set height of the support 11 can be achieved by a vertically arranged telescopic mechanism such as an electric telescopic rod. The electric telescopic rod is fixed to the connection end 21, and then the acting end of the electric telescopic rod is connected to the support 11. By controlling the telescopic movement of the electric telescopic rod, the set height of the support 11 can be adjusted; it can also be achieved by a screw rod and a moving block connected by a thread. The screw rod is vertically arranged and one end of the screw rod is rotatably connected to the connection end 21. The support 11 is fixedly connected to the moving block. By rotating the screw rod to drive the moving block to move vertically, the set height of the support 11 can be adjusted; as long as the set height of the wiper 1 relative to the connection end 21 can be adjusted, there is no limitation here.

[0040] For example, in some embodiments, as Figure 2 shown, the height adjustment mechanism 3 includes an adjustment bolt 31 and an elastic member 32. The connection end 21 and the support 11 are vertically distributed and each has a corresponding connection hole. One of the connection holes is a through hole, and the other connection hole is a threaded hole. In this embodiment, the connection hole of the connection end 21 is set as a through hole, and the connection hole of the support 11 is set as a threaded hole. The elastic member 32 is disposed between the through hole end 211 and the threaded hole end 111, and the first end of the adjustment bolt 31 passes through the through hole from the outside of the through hole end 211 and is connected to the threaded hole of the threaded hole end 111, so that the second end of the adjustment bolt 31 abuts against the outside of the through hole end 211. At this time, one end of the elastic member 32 acts on the through hole end 211, and the other end acts on the threaded hole end 111, providing elastic axial support between the connection end 21 and the support 11, and pressing the through hole end 211 against the second end of the adjustment bolt 31. Since the position height of the connection end 21 remains unchanged, by rotating the adjustment bolt 31 clockwise or counterclockwise to adjust its tightening depth, the position height of the support 11 can be adjusted, and further the wiper force of the wiper 1 relative to the outer surface of the roof sky screen 5 can be adjusted. The overall structure is simple, compact, and easy to operate, and can quickly adjust the position height of the support 11.

[0041] Furthermore, as Figure 2 shown, the elastic member 32 is set as a compression spring. In this way, the first end of the adjustment bolt 31 can pass through the through hole and the compression spring in sequence to be connected to the threaded hole, so that both ends of the elastic member 32 respectively abut against the relative inner sides of the connection end 21 and the support 11, improving the connection stability of the elastic member 32 and enabling the moment transfer of the elastic member 32 to be balanced.

[0042] Preferably, as Figure 2As shown, the bracket 11 can be arranged above the connection end 21. In this way, the distance between the two can be reduced by tightening the adjusting bolt 31, so that the position height of the bracket 11 is reduced, and the brushing force of the wiper 1 is increased, and the operation is convenient and fast. It can be understood that when the above-mentioned height adjustment mechanism 3 is the adjusting bolt 31 and the elastic member 32, there are differences in the height adjustment control methods based on the up-and-down position distribution relationship between the connection end 21 and the bracket 11. For example, when the bracket 11 is located below the connection end 21, the distance between the two can also be increased by loosening the adjusting bolt 31, so that the position height of the bracket 11 is reduced, and the brushing force of the wiper 1 is increased.

[0043] In some embodiments, such as Figure 1 , Figures 3 to 5 As shown, the roof sky curtain cleaning structure further includes a groove 41 provided on the outer surface of the roof sheet metal 4 corresponding to one end of the driving device 2. One end of the driving device 2 bends downward along the profile curve of the groove 41 and extends into the groove 41, so that the wiper 1 can be driven to be received in the groove 41. In this way, when there is no need to brush the roof sky curtain 5, the wiper 1 can be hidden in the groove 41 to achieve the purposes of reducing wind resistance, protecting the wiper member 12 to improve its service life, and avoiding affecting the aesthetic appearance.

[0044] For example, in this embodiment, one end of the slide rail 22 can be designed to sink along the profile curve of the groove 41 at the groove 41, and the transmission belt 241 is arranged along the slide rail 22 in a conforming manner, that is, the movement track of the sliding connection member 23 sinks to the groove 41 along the shape of the slide rail 22. When the wiper 1 moves to the groove 41 along with the sliding connection member 23, its accommodation in the groove 41 is realized. Preferably, the groove 41 is arranged at the rear side in the vehicle body length direction, which can improve the structural aesthetics and avoid affecting the field of view of the passengers in the front upper part.

[0045] Furthermore, as Figure 4 shown, when the wiper 1 is received in the groove 41, the top end face of the wiper 1 is flush with the outer surface of the roof sheet metal 4, achieving the effect of completely hiding the wiper 1.

[0046] Furthermore, as Figure 5 shown, a sealing rubber 13 can also be arranged circumferentially on the bracket 11 of the wiper 1 to seal and isolate the inner area of the groove 41, so as to prevent external sundries or rainwater from entering the groove 41 when the wiper 1 is received in the groove 41.

[0047] It can be understood that the dirt accumulated and stuck on the outer surface of the roof awning 5 falls off after being scraped by the scraper 1. When the scraper 1 returns to the groove 41, some of the dirt may be pushed into the groove 41 by the scraper 1. The cleaning of this part of the dirt can be achieved by connecting the groove 41 to the drainage and diversion structure of the roof; or by extending one end of the driving device 2 to the side away from the roof awning 5 to the top of the roof sheet metal 4, so that the scraper 1 moves to the groove 41 and then performs a certain amount of excessive movement, so that this part of the dirt is taken out of the groove 41, and the dirt is removed by combining the cleaning and drainage functions of the front and rear windshields or the high-speed wind force during driving.

[0048] In some embodiments, Figure 1 As shown, the roof curtain cleaning structure also includes a nozzle 6, which is arranged on the outer surface of the roof sheet metal 4 and connected to the vehicle's washing system to spray washing liquid on the roof curtain 5. In this way, the cleaning effect of the roof curtain 5 can be further improved in conjunction with the scraper 1. Similarly, the dirt and used washing liquid left on the roof can be removed by combining the cleaning and drainage functions of the front and rear windshields or the high-speed wind during driving.

[0049] For example, a washing water pipe of the washer liquid pot can be branched out and extended along the vehicle body, such as the B-pillar or the C-pillar, to the roof sheet metal 4 and connected to the nozzle 6. The nozzle 6 can be set toward the roof skylight 5 to spray the washing liquid on the roof skylight 5, thereby effectively improving the cleaning ability of the scraper 1.

[0050] In addition, if Figure 1 and Figure 2 As shown, the embodiment of the present application also provides a vehicle, including a luggage rack 7 and the above-mentioned roof canopy cleaning structure, the luggage rack 7 is extended along the length direction of the vehicle and fixed to one side of the roof canopy 5 in the vehicle width direction; the luggage rack 7 is defined with an inner cavity 71 extending along the length direction of the vehicle, and one side of the inner cavity 71 is provided with an opening 72 extending along the length direction of the vehicle; the drive device 2 is arranged in the inner cavity 71, and the connecting end 21 extends out of the inner cavity 71 from the opening 72 and is connected to the bracket 11. In this way, the drive device 2 can be supported, built, hidden and protected by the roof luggage rack 7, which can not only improve the service life of the drive device 2, but also further reduce the wind resistance coefficient and make the shape beautiful.

[0051] For example, Figure 1 , Figure 2 and Figure 4As shown in the figure, the luggage rack 7 is fixed to one side in the vehicle width direction of the roof skylight 5, and both ends of the luggage rack 7 extend along the vehicle length direction to exceed both ends of the roof skylight 5 in the vehicle length direction; the slide rail 22 and the drive assembly 24 are fixedly embedded in the inner cavity 71 along the luggage rack 7. One end of the sliding connector 23 is slidably connected to the slide rail 22, and the other end, as the connection end 21, extends out of the inner cavity 71 from the opening 72 and is connected to the bracket 11. The drive assembly 24 drives the sliding connector 23 and the corresponding connected wiper 1 to move along the slide rail 22 to clean the roof skylight 5; when there is a groove 41 on the roof, one end of the luggage rack 7 extends into the groove 41. In this way, the movement track of the sliding connector 23 follows the shape design of the luggage rack 7 and is completely hidden under the luggage rack 7. After the cleaning is completed, when the wiper 1 moves to the groove 41 along with the sliding connector 23, it is stored in the groove 41. At this time, the wiper 1, the driving device 2, and the height adjustment mechanism 3 are all hidden by the luggage rack 7 and the groove 41, with an overall beautiful shape, and the service life of the roof skylight cleaning structure is improved, and the wind resistance coefficient is further reduced.

[0052] Furthermore, as Figure 2 shown, a sealing strip 73 can also be provided in the circumferential direction of the connection end 21 at the opening 72 to prevent rainwater or sundries from entering the inner cavity 71 and ensure a relatively isolated working environment for the driving device 2.

[0053] Further, as Figure 1 shown, the nozzle 6 can also be arranged on the luggage rack 7, which can not only raise the installation height of the nozzle 6 and improve the spraying coverage range of the washing liquid, but also avoid opening holes in the roof sheet metal 4, improving the vehicle's sealing performance and aesthetic appearance.

[0054] Preferably, as Figure 1 shown, in this embodiment, there are two luggage racks 7, including the luggage racks 7 and 7', and the two luggage racks 7 / 7' are respectively located on both sides in the vehicle width direction of the roof skylight 5 and are parallel to each other; correspondingly, there are also two sets of driving devices 2, and the two sets of driving devices 2 / 2' are respectively located in the luggage racks 7 on both sides. The wiper 1 is vertically arranged between the two sets of driving devices 2 / 2', and both ends of the bracket 11 are respectively connected to the driving devices 2 / 2' on both sides, further improving the moving stability and supporting strength of the wiper 1. In addition, when multiple sets of driving devices 2 all use transmission belts to cooperate with the driving and driven ends for transmission, at least one set of the driving components 24 of the driving device 2 has a driving motor at the driving end 242, and the driven end 243 of the driving component 24 of this set of driving devices 2 can be set as a driven wheel, while the driving and driven ends of the driving components of other sets of driving devices can also be set as driven wheels to further reduce the number of motors, simplify the structural layout, and reduce space occupation.
