[0029] Please refer to Figures 1 to 7, a description is now provided for the sky curtain cleaning wiper arm structure and vehicle provided by the present utility model. The sky curtain cleaning wiper arm structure includes a lower support base 1, a rotary drive member 2, a lifting sleeve 3, and a wiper arm body 4. The lower support base 1 is connected to the outer end of the telescopic arm 8. The lower support base 1 is provided with a vertically penetrating guide cylinder 11. The lifting sleeve 3 is slidably connected within the guide cylinder 11. The wiper arm body 4 is connected below the lifting sleeve 3. The rotary drive member 2 is located outside the guide cylinder 11 and has an output shaft extending into the lifting sleeve 3. A vertically extending swing dial 21 is connected to the output shaft. The swing dial 21 has a vertically penetrating mating cavity 22. A mating shaft 31 extending radially into the mating cavity 22 is connected to the lifting sleeve 3. A guide groove 12 for guiding and limiting the mating shaft 31 is provided on the peripheral wall of the guide cylinder 11;

[0030] Among them, the swing dial 21 can drive the mating shaft 31 to move along the guide groove 12, so that the lifting sleeve 3 drives the wiper arm body 4 to swing horizontally and open and move downward to abut against the sky curtain.

[0031] Compared with the prior art, the sky curtain cleaning wiper arm structure provided in this embodiment drives the swing dial 21 to swing vertically through the rotary drive member 2. The swing dial 21 uses the mating cavity 22 to drive the mating shaft 31 to swing horizontally along the guide groove 12 of the guide cylinder 11 to the open state, and at the same time moves the wiper arm body 4 downward to abut against the top wall of the sky curtain, facilitating the cleaning of the top wall of the sky curtain by the wiper arm body 4 driven by the telescopic movement of the telescopic arm 8, increasing the cleaning area, and ensuring the cleaning effect.

[0032] Specifically, the lifting sleeve 3 protrudes downward from the guide cylinder 11, which is convenient for connecting with the wiper arm body 4. The top of the wiper arm body 4 can be directly connected to the peripheral wall of the lifting sleeve 3, or can be connected by means of other structures. The mating shaft 31 extends horizontally in the radial direction of the lifting sleeve 3 and is fixedly connected to the lifting sleeve 3. The mating shaft 31 penetrates the peripheral wall of the lifting sleeve 3 and extends into the guide groove 12 of the guide cylinder 11.

[0033] Driven by the rotary drive member 2, the swing dial 21 rotates, and then drives the mating shaft 31 through the mating cavity 22. Under the limiting action of the guide groove 12, the mating shaft 31 drives the lifting sleeve 3 to rotate and can also drive the lifting sleeve 3 to move up and down. At this time, not only is there a circumferential rotation between the lifting sleeve 3 and the lifting sleeve 3, but also an axial sliding. A circumferential and axial relative sliding is formed between the outer peripheral wall of the lifting sleeve 3 and the inner peripheral wall of the lifting sleeve 3. Then, the wiper arm body 4 is driven by the lifting sleeve 3 to swing horizontally to an appropriate angle and move downward to abut against the top wall of the sky curtain, facilitating the subsequent cleaning of the top wall of the sky curtain.

[0034] In the initial state, the extending direction of the scraping arm body 4 is consistent with that of the telescopic arm 8, which facilitates the installation and storage of the structure and saves space occupancy. When the lifting sleeve 3 rotates around the axis driven by the mating shaft 31, it can drive the connecting rod 41 to swing horizontally synchronously with the scraping arm body 4 until it forms a certain angle with the telescopic arm 8, realizing the opening of the scraping arm body 4 to meet subsequent cleaning requirements.

[0035] Specifically, the guiding groove 12 can adopt a groove structure extending obliquely, enabling the scraping arm body 4 to move downward while opening. Additionally, the guiding groove 12 can also adopt a groove structure combining circumferential and axial extensions along the guiding cylinder 11, guiding the scraping arm body 4 to swing horizontally and open or move vertically downward at different times to realize the position transformation of the scraping arm body 4.

[0036] In some possible implementation manners, the above-mentioned feature guiding groove 32 adopts the structure as Figure 4 shown. Refer to Figure 4 , the guiding groove 12 includes a circumferential guiding groove 14 and an axial guiding groove 13. The circumferential guiding groove 14 extends along the circumference of the guiding cylinder 11, and the axial guiding groove 13 extends along the axis of the guiding cylinder 11. The circumferential guiding groove 14 is connected to the upper end of the axial guiding groove 13 and is in communication with the axial guiding groove 13.

[0037] In this embodiment, the guiding groove 32 adopts the form of combination of the circumferential guiding groove 14 and the axial guiding groove 13. The mating shaft 31 drives the lifting sleeve 3 to rotate under the guidance of the circumferential guiding groove 14, and then swings the scraping arm body 4 horizontally to a position with a certain included angle with the telescopic arm 8. After that, the mating shaft 31 drives the lifting sleeve 3 to move downward to abut against the top wall of the awning under the guidance of the axial guiding groove 13, meeting the abutting requirement of the scraping arm body 4 against the top wall of the awning, facilitating the cleaning of the top wall of the awning driven by the telescopic movement of the telescopic arm 8.

[0038] In some possible implementation manners, refer to Figures 2 to 7 , the scraping arm body 4 is connected to the lifting sleeve 3 through a connecting rod 41. The two ends of the connecting rod 41 are respectively rotatably connected to the scraping arm body 4 and the lifting sleeve 3. A lower pressing plate 5 located inside the lifting sleeve 3 is connected to the scraping arm body 4. The lower pressing plate 5 is slidably matched with the lifting sleeve 3. An elastic member 51 is provided between the lower pressing plate 5 and the lifting sleeve 3. The elastic member 51 is used to pull down the lower pressing plate 5 so that the scraping arm body 4 elastically presses against the awning.

[0039] In this embodiment, one end of the wiper arm body 4 is slidably connected to the lifting sleeve 3 through the lower pressing plate 5. The other end of the wiper arm body 4 extends radially outward along the lifting sleeve 3 and is connected to the lower end of the connecting rod 41. Both ends of the connecting rod 41 are rotatably connected to the lifting sleeve 3 and the wiper arm body 4 respectively. When the lifting sleeve 3 moves downward, the angle between the connecting rod 41 and the wiper arm body 4 slightly decreases, forming a downward pressing effect on the outer end of the wiper arm body 4. At this time, under the downward pulling action of the elastic member 51, the lower pressing plate 5 can drive the inner end of the wiper arm body 4 to elastically press against the top wall of the awning, avoiding damage to the awning caused by rigid collision between the wiper arm body 4 and the awning. The above structure can not only meet the horizontal swinging requirement of the wiper arm body 4, but also enable the wiper arm body 4 to effectively press against the top wall of the awning below, ensuring the cleaning effect of the wiper arm body 4 on the awning.

[0040] When the wiper arm body 4 is in a non-use state, it is located at a higher position close to the bottom wall of the lower support base 1, which is convenient for the swinging and opening of the telescopic arm 8. When subsequent cleaning is required, the wiper arm body 4 swings horizontally and opens under the drive of the lifting sleeve 3 and moves downward to a position where it presses against the top of the awning, realizing the process of position change.

[0041] Specifically, the axial guiding groove 13 provided on the guiding cylinder 11 is connected to the lower end of one end of the circumferential guiding groove 14. After the mating shaft 31 moves along the circumferential guiding groove 14 to the position where the wiper arm body 4 is opened, the mating shaft 31 can continue to move downward along the axial guiding groove 13, thereby driving the lifting sleeve 3, the connecting rod 41 and the wiper arm body 4 to move downward, and further enabling the wiper arm body 4 to form an effect of pressing against the top wall of the awning, ensuring effective contact with the top wall of the awning.

[0042] It should be noted that the connecting rod 41 and the connecting vertical rod 52 act on both ends of the wiper arm body 4 respectively. When driving the wiper arm body 4 to swing horizontally and move vertically downward, the force on the wiper arm body 4 is more uniform, which helps to enhance the cleaning effect of the wiper arm body 4 on the top wall of the awning.

[0043] In some embodiments, the above-mentioned feature lower pressing plate 5 can adopt the structure as Figures 4 to 5 shown. Referring to Figures 4 to 5 , the lower pressing plate 5 is connected to the wiper arm body 4 through the connecting vertical rod 52. The connecting vertical rod 52 penetrates through the bottom wall of the lifting sleeve 3. The elastic member 51 is sleeved on the outer periphery of the connecting vertical rod 52. The upper end of the elastic member 51 is connected to the bottom wall of the lower pressing plate 5, and the lower end of the elastic member 51 is connected to the inner bottom wall of the lifting sleeve 3. The elastic member 51 is used to elastically pull down the lower pressing plate 5.

[0044] In this embodiment, a connecting vertical rod 52 extending upward into the lifting sleeve 3 is connected to the scraping arm body 4. The bottom wall of the lower pressing plate 5 is connected to the upper end of the connecting vertical rod 52, and the elastic member 51 is connected between the lower pressing plate 5 and the inner bottom wall of the lifting sleeve 3. When the lifting sleeve 3 moves downward, the scraping arm body 4 follows and moves downward to contact the top wall of the awning. At this time, the positions of the scraping arm body 4, the connecting vertical rod 52, and the lower pressing plate 5 remain unchanged, and the elastic member 51 is stretched, forming a downward pulling force on the lower pressing plate 5 to ensure that the scraping arm body 4 can elastically press against the top wall of the awning, meeting the subsequent cleaning requirements of the scraping arm body 4 for the awning.

[0045] In some embodiments, the above-mentioned features of the lifting sleeve 3 and the lower pressing plate 5 can be adopted as Figure 5 and Figure 7 shown in the structure. Refer to Figure 5 and Figure 7 . On the inner wall of the lifting sleeve 3, there are several axially extending guide grooves 32, and on the outer periphery of the lower pressing plate 5, there are several guide blocks 53 arranged in one-to-one correspondence with the guide grooves 32. The guide blocks 53 are in sliding fit with the guide grooves 32.

[0046] In this embodiment, the guide grooves 32 on the inner wall of the lifting sleeve 3 are used to guide and limit the guide blocks 53 on the outer periphery of the lower pressing plate 5, effectively limiting the circumferential position of the lower pressing plate 5. When the lower pressing plate 5 slides relative to the lifting sleeve 3, it can maintain the stability of the circumferential position, facilitating the synchronous driving of the scraping arm body 4 to swing horizontally to the open state by the connecting rod 41, improving the smoothness of the structural movement, and avoiding jamming problems.

[0047] In some possible implementation manners, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 . There are two sets of the guide cylinder 11, the lifting sleeve 3, and the scraping arm body 4. The rotary driving member 2 is respectively connected to the two swing seats 21 through the gear transmission assembly 6. The axially guiding grooves 13 on the two guide cylinders 11 are respectively located at one end of the two circumferentially guiding grooves 14 that are far away from each other.

[0048] In this embodiment, in order to improve the cleaning efficiency, two scraping arm bodies 4 are provided. Therefore, the numbers of the lifting sleeve 3, the guide cylinder 11, and the swing seat 21 are two. The gear transmission assembly 6 is used to drive the two scraping arm bodies 4 to move synchronously, improving the cleaning efficiency of the awning.

[0049] The rotation directions of the two lifting sleeves 3 are set to be opposite, so that the two scraping arm bodies 4 swing open towards the front and rear sides respectively. The axially guiding grooves 13 on the two guide cylinders 11 are respectively located at the opposite ends of the two circumferentially guiding grooves 14, so that the horizontal swing directions of the two scraping arm bodies 4 are opposite, avoiding position interference during their opening process, and at the same time expanding the area range that the scraping arm body 4 can clean.

[0050] In some embodiments, the above-described characteristic gear transmission assembly 6 may adopt a structure as shown in Figure 1 , Figure 2 and Figure 4 . Referring to Figure 1 , Figure 2 and Figure 4 , the gear transmission assembly 6 includes a first gear 61, a first shaft 62, a second gear 63, a third gear 64, a second shaft 65, and a fourth gear 66. The first gear 61 is connected to the output shaft of the rotary drive member 2. The first shaft 62 and the second shaft 65 are respectively rotatably connected to the lower support 1 and are respectively arranged parallel to the output shaft of the rotary drive member 2. The first shaft 62 and the second shaft 65 respectively extend into two lifting sleeves 3 in a one-to-one correspondence. Swing dial seats 21 are respectively connected to the first shaft 62 and the second shaft 65. The second gear 63 and the third gear 64 are respectively sleeved on the outer periphery of the first shaft 62. The second gear 63 meshes with the first gear 61. The fourth gear 66 is sleeved on the outer periphery of the second shaft 65 and meshes with the third gear 64.

[0051] In this embodiment, the second rotary drive member 2 is used to drive the first gear 61 to rotate. The driving effect on the first shaft 62 is achieved through the cooperation of the first gear 61 and the second gear 63. The third gear 64 rotates synchronously with the first shaft 62, driving the fourth gear 66 and the second shaft 65 to rotate synchronously. The first shaft 62 and the second shaft 65 are respectively used to drive the two swing dial seats 21 to rotate, thereby realizing the synchronous driving effect on the two lower scraping arm bodies 4.

[0052] In some possible implementation manners, the above-described characteristic scraping arm body 4 adopts a structure as shown in Figure 7 . Referring to Figure 7 , a spray head 7 is further provided above the scraping arm body 4. The spray head 7 is arranged towards the side of the scraping arm body 4. The spray head 7 is used to spray windshield washer fluid onto the top wall of the sunroof. The spray head 7 above the scraping arm body 4 is arranged towards the side of the scraping arm body 4, which can spray the windshield washer fluid on the top wall of the sunroof, facilitating the dissolution of impurities on the sunroof and helping to effectively remove the impurities under the action of the scraping arm body 4.

[0053] In some possible implementation manners, the above-described characteristic swing dial seat 21 adopts a structure as shown in Figure 1 and Figure 7 . Referring to Figure 1 and Figure 7 , the swing dial seat 21 includes a connecting block 23 and two vertical rods 24. The connecting block 23 is connected to the output shaft of the rotary drive member 2. The two vertical rods 24 are respectively connected to both sides of the connecting block 23. The two vertical rods 24 and the connecting block 23 enclose a mating cavity 22.

[0054] In this embodiment, the swinging dial seat 21 uses the connecting block 23 and the two vertical rods 24 on both sides to enclose a vertically penetrating fitting cavity 22. The swinging dial seat 21 swings vertically driven by the gear drive assembly. By using the side cavity wall of the fitting cavity 22 to contact the peripheral wall of the fitting shaft 31, a driving effect on the fitting shaft 31 is formed, enabling the lifting sleeve 3 to smoothly move along the guiding groove 32, and further realizing the driving effect on the wiper arm body 4, meeting the subsequent cleaning function of the wiper arm body 4.

[0055] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, which includes a sky screen cleaning wiper arm structure. The above vehicle drives the swinging dial seat 21 to swing vertically through the rotation drive member 2. The swinging dial seat 21 drives the fitting shaft 31 to horizontally swing open to the open state along the guiding groove 12 of the guiding cylinder 11 by using the fitting cavity 22. At the same time, the wiper arm body 4 is moved downward to abut against the top wall of the sky screen, facilitating the cleaning of the top wall of the sky screen by the wiper arm body 4 driven by the telescopic movement of the telescopic arm 8, increasing the cleaning area and ensuring the cleaning effect.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
