[0027] Please also read Figures 1 to 5 , the scraper arm telescopic drive structure and the vehicle provided by the utility model are now described. The scraper arm telescopic drive structure is connected to the roof of the vehicle, and the scraper arm telescopic drive structure includes a transverse frame 1, a folding spring 2, a tensioning rope 3 and a winding assembly 6. The transverse frames 1 are provided with a plurality of transverse frames 1, and the plurality of transverse frames 1 are sequentially slidably connected in the horizontal direction. The folding spring 2 is arranged between two adjacent transverse frames 1, and the winding assembly 6 is connected to the transverse frame 1 at the outer end. One end of the tensioning rope 3 is connected to the transverse frame 1 at the inner end, and the other end is connected to the winding assembly 6;

[0028] Among them, the folding spring sheet 2 is used to elastically push two adjacent transverse frames 1 so that the two transverse frames 1 move away from each other and extend outward. The winding component 6 pulls the inner end of the transverse frame 1 through the tensioning rope 3 to fold the folding spring sheet 2 and retract several transverse frames 1 in turn.

[0029] Compared with the prior art, the scraper arm telescopic driving structure provided by the present embodiment adopts a structural form in which multiple transverse frames 1 slide and cooperate with each other. Two adjacent transverse frames 1 are slidably connected, and under the action of the folding spring sheet 2, the two adjacent transverse frames 1 move away from each other to achieve outward extension; when contraction is required, the winding component 6 pulls the transverse frame 1 at the inner end through the tensioning rope 3 to overcome the elastic force of the folding spring sheet 2, so that the two adjacent transverse frames 1 move closer to each other and form a retraction effect, which is convenient for driving the scraper arm 5 to reciprocate and clean the top of the canopy. The above structure effectively reduces the space occupied by the structure and ensures the driving effect of the scraper arm 5.

[0030] For the sake of convenience, the transverse frame 1 connected to the roof is defined as the inner end transverse frame 1, and the transverse frame 1 that can be extended outward to the outermost end is defined as the outer end transverse frame 1. The winding assembly 6 is connected to the transverse frame 1 at the outer end, and a pulling force can be formed on the transverse frame 1 at the inner end by tightening the rope 3, so that the transverse frame 1 at the outer end gradually moves toward the transverse frame 1 close to the inner end, thereby realizing the retraction and folding of the structure.

[0031] In this embodiment, during the cleaning process of the scraper arm 5, the elastic action of the folded spring sheet 2 is utilized to push the transverse frame 1 outward, and the winding assembly 6 pulls the multiple transverse frames 1 back through the tensioning rope 3, thereby realizing the horizontal driving effect on the scraper arm 5, causing the scraper arm 5 to move horizontally, thereby realizing effective cleaning of the top wall of the canopy, ensuring effective coverage of the top of the canopy, and improving the comprehensiveness of cleaning.

[0032] In a possible implementation, the above-mentioned characteristic transverse moving frame 1 can be used as follows Figures 1 to 5 See the structure shown. Figures 1 to 5 The transverse moving frame 1 includes a mounting end plate 11 and a plurality of guide rods 12 connected to the same side of the mounting end plate 11. The guide rods 12 extend in the horizontal direction. The guide rod 12 of one of the two adjacent transverse moving frames 1 slides with the mounting end plate 11 of the other one. The folding spring sheet 2 is located between the mounting end plates 11 of the two adjacent transverse moving frames 1 and is used to drive the two transverse moving frames 1 to move in opposite directions and extend outward. The mounting end plates 11 are provided with a clearance hole 13 for the tensioning rope 3 to pass through.

[0033] In this embodiment, the transverse moving frame 1 adopts a structure combining a guide rod 12 and a mounting end plate 11 , and two adjacent transverse moving frames 1 can slide relative to each other to achieve a telescopic action, thereby achieving a horizontal driving effect on the scraper arm 5 .

[0034] For ease of description, a first transverse frame 1 connected to the vehicle body and a second transverse frame 1 slidably connected to the outer end of the first transverse frame 1 are defined. The guide rod 12 of the first transverse frame 1 extends horizontally outward perpendicular to the plate surface of the mounting end plate 11, and two to four guide rods 12 are provided to ensure the structural strength of the first transverse frame 1 and meet the support requirements of the second transverse frame 1. The guide rod 12 of the first transverse frame 1 is provided through the mounting end plate 11 of the second transverse frame 1, and the mounting end plate 11 of the second transverse frame 1 is slidably matched with the guide rod 12 of the first transverse frame 1. The guide rod 12 of the second transverse frame 1 extends to the side away from the first transverse frame 1, and the mounting end plate 11 of the second transverse frame 1 is slidably matched with the guide rod 12 of the first transverse frame 1.

[0035] When the structure needs to extend outward, the tension rope 3 is gradually unwound and released, and the second transverse frame 1 can move to the side away from the first transverse frame 1 under the elastic force of the folding spring sheet 2, forming an outward extension and opening action, driving the scraper arm 5 to extend outward. When the structure needs to retract inward, the tension rope 3 is ensured to be in a tensioning state, at which time the folding spring sheet 2 is folded under force, and the second transverse frame 1 moves to the side close to the first transverse frame 1 to achieve a retracting effect.

[0036] It should be noted that, for each transverse frame 1, mounting end plates 11 can be respectively provided at both ends of the guide rod 12. At this time, the mounting end plate 11 on the side adjacent to the second transverse frame 1 and the first transverse frame 1 is slidably matched with the guide rod 12 of the first transverse frame 1, and is located between the two mounting end plates 11 of the first transverse frame 1, thereby preventing the second transverse frame 1 from falling off from the outer end of the first transverse frame 1.

[0037] As a parallel embodiment, if each transverse frame 1 includes only one mounting end plate 11 and multiple guide rods 12, the outer end of the guide rod 12 is provided with a limiting boss 14 protruding toward the outer periphery, and the limiting boss 14 is used to limit the sliding range of the mounting end plate 11 of the adjacent transverse frame 1.

[0038] In this embodiment, a limiting boss 14 protruding toward the outer periphery is provided at the outer end of the guide rod 12, and the limiting boss 14 is used to limit the sliding range of the mounting end plate 11 of the second transverse frame 1 to prevent it from falling off the guide rod 12 of the first transverse frame 1.

[0039] When the tensioning rope 3 is in a relaxed state, the second transverse frame 1 moves to the side away from the first transverse frame 1 under the elastic force of the folded spring sheet 2 until the end face of the mounting end plate 11 of the second transverse frame 1 abuts against the limiting boss 14 at the outer end of the guide rod 12 of the first transverse frame 1. At this time, the second transverse frame 1 is located at the outermost end of the first transverse frame 1. Similarly, the subsequent third, fourth and other transverse frames 1 also move outward to the extreme position, so that the overall length of the structure is extended to the maximum, and then the tensioning rope 3 is pulled to retract the structure and drive the scraper arm 5 to scrape and clean the top surface of the canopy, which has a good cleaning effect.

[0040] In a possible implementation, the above-mentioned characteristic transverse moving frame 1 can be used as follows Figures 1 to 5 See the structure shown. Figures 1 to 5 The transverse frame 1 also includes a plurality of intermediate slides 4 slidably connected to the guide rod 12, and the intermediate slides 4 are penetrated with avoidance holes 41 for the tensioning rope 3 to pass through. The folding spring sheet 2 is arranged between two adjacent intermediate slides 4, or between the mounting end plate 11 and the intermediate slide 4.

[0041] In this embodiment, the guide rod 12 has a certain extension length. In order to ensure that the two transverse frames 1 can effectively extend away from each other, a plurality of intermediate slides 4 are also arranged on the guide rod 12 of the transverse frame 1. The plurality of intermediate slides 4 are respectively slidably connected to the guide rod 12, and a folding spring sheet 2 is respectively arranged between two adjacent intermediate slides 4. The overall elastic effect of the plurality of folding spring sheets 2 is utilized to realize effective pushing of the outer end transverse frame 1, thereby improving the overall elastic force of the structure, reducing the number of transverse frames 1 arranged, improving the stability of the structure, and ensuring the overall size requirements.

[0042] It should be noted that the middle slide 4 is provided with an avoidance hole 41 corresponding to the horizontal level of the avoidance hole 13 , and the avoidance hole 41 is used for the tensioning rope 3 to pass through so that the tensioning rope 3 is connected to the mounting end plate 11 of the transverse frame 1 farthest from the scraper arm 5 .

[0043] In some embodiments, see Figure 5 The mounting end plate 11 and the middle slide 4 are both rectangular plate-shaped components, the guide rod 12 is set through the middle slide 4, and the two ends of the folding spring sheet 2 are respectively connected between the corresponding side edges of two adjacent middle slides 4, or respectively connected between the mounting end plate 11 and the corresponding side edges of the middle slide 4.

[0044] In this embodiment, the mounting end plate 11 and the middle slide 4 are rectangular plate-shaped components, which are convenient for processing and manufacturing on the one hand, and also convenient for positioning the guide rod 12 on the other hand. The folding spring sheet 2 is used to elastically push two adjacent middle slides 4 to move them away from each other, or to elastically push the mounting end plate 11 and the middle slide 4 adjacent to the mounting end plate 11, and finally form an elastic pushing effect on the rear end transverse frame 1, so as to realize the mutual distance between the two adjacent transverse frames 1, thereby driving the scraper arm 5 to move horizontally.

[0045] In some embodiments, the same transverse frame 1 is provided with four guide rods 12, and the four guide rods 12 are evenly spaced along the circumference of the middle slide 4. The four guide rods 12 meet the structural strength requirements of the transverse frame 1, and can also form a sliding guide for adjacent transverse frames 1.

[0046] Specifically, the four guide rods 12 of the first transverse frame 1 connected to the vehicle body are respectively arranged near the four corners of the mounting end plate 11 or the middle slide 4, and the four guide rods 12 of the second transverse frame 1 connected to the outer end of the first transverse frame 1 are respectively arranged near the middle of each edge of the mounting end plate 11 or the middle slide 4 of the second transverse frame 1, so that the guide rods 12 of two adjacent transverse frames 1 are staggered in the longitudinal section. The arrangement of the guide rods 12 of the subsequent third transverse frame 1 is consistent with the arrangement of the guide rods 12 of the first guide frame, and the arrangement of the guide rods 12 of the fourth transverse frame 1 is consistent with the arrangement of the guide rods 12 of the second guide frame.

[0047] In one possible implementation, see Figure 1 to Figure 2 The lateral frame 1 at the outermost end is provided with a connecting plate 15 connected to the scraper arm 5, and the connecting plate 15 is connected to the outer end of the guide rod 12. The lateral frame 1 at the outermost end is provided with a connecting plate 15 for connecting to the arm body, which ensures the structural integrity of the lateral frame 1 and improves the reliability of the connection with the scraper arm 5.

[0048] In a possible implementation, the above-mentioned characteristic folded spring piece 2 can be used as follows: Figure 5 See the structure shown. Figure 5 The folding spring sheet 2 includes two elastic sheets arranged at an angle, the two elastic sheets can be elastically opened to make the two transverse frames 1 move away from each other, and the opening of the angle between the two elastic sheets is arranged toward the axial center side of the transverse frame 1.

[0049] In this embodiment, the two elastic sheets of the folding spring sheet 2 are plate-like components, and the two are formed in one piece. In the natural state, there is a certain angle between the two sheets. The edges of the two elastic sheets that are away from each other are respectively connected to the two adjacent middle slides 4, so that the two middle slides 4 are away from each other, or the edges of the two elastic sheets that are away from each other are respectively connected to the middle slide 4 and the mounting end plate 11, so that the above-mentioned middle slide 4 and the mounting end plate 11 are away from each other, so that the two transverse frames 1 can be away from each other, thereby realizing the outward drive of the scraper arm 5.

[0050] In one possible implementation, see Figure 3 and Figure 4 The winding assembly 6 includes a connecting seat 61, a rope-taking roller 62 and a rotating driving member 63. The connecting seat 61 is connected to the outermost transverse frame 1, the rope-taking roller 62 is rotatably connected to the connecting seat 61, and the rotating driving member 63 is connected to the rope-taking roller 62 for driving the rope-taking roller 62 to rotate to wind and gather the tensioning rope 3.

[0051] In this embodiment, the winding action of the tension rope 3 is realized by the rope collection roller 62 on the connecting seat 61, and the rope collection roller 62 is driven to rotate by the rotary drive member 63. The rotary drive member 63 drives the rope collection roller 62 to rotate forward to wind the tension rope 3 or rotate backward to release the tension rope 3 through forward and reverse rotation, thereby meeting the telescopic requirements of the structure, and further meeting the effective cleaning of the awning by the scraper arm 5.

[0052] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, which includes a scraper arm telescopic drive structure. The above vehicle uses the scraper arm telescopic drive structure to telescope the scraper arm 5, and the multiple transverse frames 1 can achieve telescopic action under the cooperation of the folding spring sheet 2 and the tension rope 3, which meets the cleaning requirements of the scraper arm 5 for the awning, saves the space occupied by the structure, and facilitates the layout of the structure.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
