[0030] Please also read Figures 1 to 6 The telescopic arm swing and sliding structure and the vehicle provided by the utility model are now described. The telescopic arm swing and sliding structure comprises an installation box 1, a translation screw 2, a guide rail 3 and a sliding shaft seat 4. The translation screw 2 and the guide rail 3 are both arranged in the installation box 1 along the front-back direction. The translation screw 2 passes through the sliding shaft seat 4 and is threadedly matched with the sliding shaft seat 4. The sliding shaft seat 4 is slidably matched with the guide rail 3. The sliding shaft seat 4 is used to install the telescopic arm 8. One end of the translation screw 2 is connected to a reversing drive wheel set 5;

[0031] Among them, the reversing driving wheel set 5 can drive the telescopic arm 8 to swing horizontally around the sliding shaft seat 4 to the outside of the installation box 1, and the reversing driving wheel set 5 can also drive the sliding shaft seat 4 and the telescopic arm 8 to move forward and backward along the translation screw 2.

[0032] The telescopic arm swinging and sliding structure provided in the present embodiment is compared with the prior art. The translation screw 2 rotates under the drive of the reversing drive wheel group 5, thereby driving the sliding shaft seat 4 to move axially along the translation screw 2, so that the telescopic arm 8 can be moved to different front and rear areas of the canopy. In addition, the reversing drive wheel group 5 can drive the telescopic arm 8 to swing horizontally around the sliding shaft seat 4 to extend outward from the mounting box 1. The above structure can realize the outward rotation and translational action of the telescopic arm 8, simplifies the structural design, facilitates the processing and installation of the structure, and meets the different driving requirements for the telescopic arm 8.

[0033] In this embodiment, the reversing drive wheel group 5 can realize the reversal of the output power. While satisfying the requirement that the reversing drive wheel group 5 outputs power to the translation screw 2 and enables the telescopic arm 8 to move along the translation screw 2 following the sliding shaft seat 4, it can also drive the telescopic arm 8 to swing horizontally around the sliding shaft seat 4 until it extends outward from the installation box 1, thereby driving the cleaning scraper arm 9 at the outer end of the telescopic arm 8 to move out of the installation box 1, thereby facilitating the subsequent cleaning of the ceiling by the cleaning scraper arm 9.

[0034] When it is necessary to clean the awning, first use the reversing drive wheel group 5 to drive the telescopic arm 8 to swing horizontally to the outside of the installation box 1, and drive the cleaning scraper arm 9 to clean part of the awning area through the telescopic action of the telescopic arm 8. After completing the cleaning of the awning in this area, then use the translation screw 2 to drive the sliding shaft seat 4, the telescopic arm 8 and the cleaning scraper arm 9 to move forward or backward synchronously along the translation screw 2, so that the cleaning scraper arm 9 can perform corresponding cleaning on other areas of the awning.

[0035] The above-mentioned structural arrangement, on the basis of satisfying the left and right scraping cleaning of the awning by the cleaning scraper arm 9, can also utilize the cleaning scraper arm 9 driven by the translation screw 2 to effectively cover the positions of different areas in front and behind the awning, thereby ensuring comprehensive coverage of the top area of ​​the awning and meeting the cleaning needs of the awning.

[0036] Specifically, two different cleaning modes can be set: standard cleaning and directional cleaning. The standard cleaning mode refers to a comprehensive and thorough cleaning of the entire area of ​​the canopy, while the directional cleaning mode refers to a method of directional cleaning of specific dirty locations of the canopy.

[0037] In some possible implementations, the above-mentioned characteristic reversing driving wheel set 5 adopts the following method: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2The reversing driving wheel set 5 includes a first driving member 51, a driving gear 52, a transition gear 53 and a driven bevel gear 54. The output shaft of the first driving member 51 is connected to the translation screw 2, and the driving gear 52 is fixedly sleeved on the outer periphery of the output shaft of the first driving member 51;

[0038] Among them, the transition gear 53 includes an integrally formed driven gear 55 and a driving bevel gear 56, the sliding shaft seat 4 has an extension shaft 41 extending horizontally to the side close to the first driving member 51, the transition gear 53 is rotatably connected to the extension shaft 41, the driven gear 55 is meshed with the driving gear 52, the driving bevel gear 56 is meshed with the driven bevel gear 54, the driven bevel gear 54 is fixedly connected to the telescopic arm 8, and the driven bevel gear 54 can drive the telescopic arm 8 to swing horizontally under the action of the driving bevel gear 56.

[0039] In this embodiment, the reversing driving wheel set 5 can not only drive the telescopic arm 8 to swing horizontally, but also drive the telescopic arm 8 to move forward and backward. The first driving member 51 can directly drive the translation screw 2 to rotate, so that the sliding shaft seat 4 drives the telescopic arm 8 and the cleaning scraper arm 9 to move toward the front side of the vehicle body.

[0040] In some possible implementations, the above-mentioned characteristic sliding shaft seat 4 is adopted as follows Figures 2 to 4 See the structure shown. Figures 2 to 4 The sliding shaft seat 4 includes a vertical shaft 42, a translation nut 43 and a slide seat 44. The slide seat 44 is slidably connected to the guide rail 3. The translation nut 43 is threadedly sleeved on the translation screw 2. The vertical shaft 42 is connected between the translation nut 43 and the slide seat 44 along the up and down directions. The extension shaft 41 is connected to the middle part of the vertical shaft 42. The driven bevel gear 54 is sleeved on the vertical shaft 42 and is located above the extension shaft 41.

[0041] In this embodiment, the vertical shaft 42 of the sliding shaft seat 4 extends vertically, that is, extends in the up-down direction, and the extension shaft 41 extends in the horizontal direction. The extension shaft 41 is connected to the middle of the vertical shaft 42 and extends to a side close to the reversing drive wheel set 5. The transition gear 53 is rotatably connected to the extension shaft 41, and the driven bevel gear 54 is rotatably connected to the vertical shaft 42. The driven bevel gear 54 is connected to an upper shaft sleeve 57 connected to the telescopic arm 8. When the driven bevel gear 54 rotates, the telescopic arm 8 can be driven to swing out horizontally.

[0042] During use, the driving gear 52 can drive the driven gear 55 on the transition gear 53 to rotate while following the rotation of the first driving member 51. At this time, the driving bevel gear 56 rotates synchronously with the driven gear 55. The driving bevel gear 56 meshes with the driven bevel gear 54 and drives the driven bevel gear 54 to rotate. The driven bevel gear 54 is used to drive the telescopic arm 8 to rotate around the vertical axis 42, so that the telescopic arm 8 is swung out horizontally.

[0043] In some embodiments, see Figure 5 The upper part of the driven bevel gear 54 is connected to an upper sleeve 57 sleeved on the outer periphery of the vertical shaft 42, and a lower sleeve 45 is rotatably sleeved on the vertical shaft 42. The upper sleeve 57 and the lower sleeve 45 are respectively located on the upper and lower sides of the extension shaft 41, and the upper sleeve 57 and the lower sleeve 45 are respectively connected to the telescopic arm 8 through a connecting rod 46.

[0044] In this embodiment, the driven bevel gear 54 is connected to the telescopic arm 8 through the upper shaft sleeve 57, so that the telescopic arm 8 can realize the rotational coordination of the vertical shaft 42 through the upper shaft sleeve 57. The driven bevel gear 54 rotates outside under the driving bevel gear 56, so that the upper shaft sleeve 57 rotates synchronously and drives the telescopic arm 8 to rotate around the vertical shaft 42, so as to realize the effect of the telescopic arm 8 swinging out horizontally.

[0045] On this basis, a lower sleeve 45 is also rotatably sleeved on the vertical shaft 42, and the lower sleeve 45 is fixedly connected to the telescopic arm 8. In addition, a follower bevel gear 47 is also sleeved on the vertical shaft 42, and the follower bevel gear 47 is located between the driven bevel gear 54 and the lower sleeve 45, and is separated from the lower sleeve 45, and the two are independent of each other and not connected. The follower bevel gear 47 rotates with the vertical shaft 42 and can rotate with the active bevel gear 56, and cooperates with the driven bevel gear 54 to form a structure symmetrically arranged on the upper and lower sides of the active bevel gear 56, thereby improving the uniformity of force and meeting the driving requirements of the telescopic arm 8.

[0046] In some embodiments, see Figures 2 to 3 A follower bevel gear 47 is also rotatably connected to the vertical shaft 42. The driven bevel gear 54 and the follower bevel gear 47 are symmetrically located on the upper and lower sides of the active bevel gear 56. The follower bevel gear 47 is meshed with the active bevel gear 56, and the lower end surface of the follower bevel gear 47 is slidably matched with the upper end surface of the lower sleeve 45.

[0047] In this embodiment, the follower bevel gear 47 sleeved on the vertical shaft 42 is located above the lower shaft sleeve 45. The follower bevel gear 47 and the lower shaft sleeve 45 are separated from each other and are not connected. The follower bevel gear 47 can rotate with the active bevel gear 56, and cooperate with the driven bevel gear 54 to form a structure symmetrically arranged on the upper and lower sides of the active bevel gear 56, thereby improving the uniformity of force and meeting the driving requirements of the telescopic arm 8.

[0048] In some possible implementations, the characteristic extension axis 41 is as follows: Figure 3 to Figure 4 See the structure shown. Figure 3 to Figure 4The outer end of the extension shaft 41 is provided with a limiting plate 48 for limiting the axial position of the transition gear 53, and the plate surface of the limiting plate 48 is arranged perpendicular to the extension shaft 41. By setting the limiting plate 48, the axial position of the transition gear 53 (that is, the driven gear 55) can be limited to prevent the transition gear 53 from being disengaged from the outer end of the extension shaft 41, and ensure that the transition gear 53 can follow the sliding shaft seat 4 to move in an orderly manner along the axial direction of the translation screw 2, until the subsequent driven gear 55 moves to be separated from the driving gear 52, and the horizontal swinging operation of the telescopic arm 8 is completed.

[0049] In some embodiments, see Figure 3 The outer diameter of the driving gear 52 is greater than the outer diameter of the driven gear 55 , and the axial length of the driving gear 52 is less than the axial length of the driven gear 55 .

[0050] In this embodiment, when the driving gear 52 drives the driven gear 55 to rotate, the speed of the driven gear 55 and the driving bevel gear 56 can be reduced, so that the swing speed of the telescopic arm 8 can be reduced and the smoothness of the swinging action can be improved. The driven bevel gear 54 will move to the side away from the driving gear 52 following the sliding shaft seat 4, and the axial length of the driving gear 52 is smaller than the axial length of the driven gear 55, so that the meshing of the two lasts for a certain length of time, ensuring the effective opening of the telescopic arm 8.

[0051] After the telescopic arm 8 is driven by the driven bevel gear 54 to rotate 90°, the telescopic arm 8 should be able to maintain a stable state at this angle, so the axial length of the driven gear 55 should meet certain requirements. When the driving bevel gear 56 and the driven bevel gear 54 are meshed and drive the telescopic arm 8 to rotate 90°, it should be ensured that the driven gear 55 just follows the sliding shaft seat 4 and moves synchronously to disengage from the driving gear 52, so that the entire process of the driving gear 52 and the driven gear 55 meshing is consistent with the process of the driven bevel gear 54 driving the telescopic arm 8 to swing outward horizontally 90°, that is, after the telescopic arm 8 swings to the 90° position, the driving gear 52 and the driven gear 55 just disengage, completing the swinging and opening of the telescopic arm 8, and the subsequent telescopic arm 8 only moves forward and backward along the translation screw 2 under the action of the sliding shaft seat 4.

[0052] In some possible implementations, the above-mentioned characteristic telescopic arm swing sliding structure adopts the following method: Figure 2 See the structure shown. Figure 2 The telescopic arm swinging and sliding structure also includes a mounting base 6, in which a lifting assembly 7 is provided for driving the mounting box 1 to move up and down. The lifting assembly 7 can drive the mounting box 1 to move upward and protrude from the canopy, thereby causing the telescopic arm 8 to swing horizontally to the top of the canopy and clean the top wall of the canopy with the help of the cleaning scraper arm 9.

[0053] In this embodiment, the mounting base 6 is fixedly connected to one side of the top of the vehicle body, that is, located at the side of the canopy. The top surface of the mounting base 6 is flush with the top wall of the canopy, and the lifting assembly 7 can drive the mounting box 1 and its internal telescopic arm 8 and cleaning scraper arm 9 and other components to protrude upward from the upper edge of the mounting base 6, that is, protrude upward from the top wall of the canopy, thereby making the telescopic arm 8 and the cleaning scraper arm 9 higher than the canopy, so as to facilitate the swinging and opening of the telescopic arm 8.

[0054] In some embodiments, the feature lifting assembly 7 can be used as follows: Figures 2 to 3 See the structure shown. Figures 2 to 3 The lifting assembly 7 includes a second driving member 71, a horizontal shaft 72, two sets of bevel gear sets 73 and a lifting screw 74. The horizontal shaft 72 is rotatably connected to the inner bottom of the mounting base 6. The horizontal shaft 72 is connected to the output shaft of the second driving member 71. The two sets of bevel gear sets 73 are respectively arranged at both ends of the horizontal shaft 72. The lifting screws 74 are respectively rotatably connected to the inner wall of one side of the mounting base 6 along the up and down directions and are respectively located at both ends of the mounting box 1. The two ends of the mounting box 1 are respectively provided with lifting nuts 11 that are threadedly matched with the lifting screws 74 one by one. The lifting screws 74 can drive the mounting box 1 to move up and down under the action of the bevel gear set 73.

[0055] In this embodiment, the lifting assembly 7 adopts the transmission method of the second driving member 71 to drive the horizontal shaft 72 and the bevel gear group 73, and the bevel gear group 73 is used to rotationally drive the lifting screw 74. The lifting screw 74 is rotatably connected to the mounting base 6 through the mounting seat 61. The mounting seat 61 is connected to the side wall of the mounting base 6. The lifting nut 11 on the outside of the mounting box 1 is threadedly matched with the lifting screw 74. The lifting nut 11 can drive the mounting box 1 to move upward, thereby facilitating the horizontal swing of the telescopic arm 8 in the mounting box 1.

[0056] The second driving member 71 can drive the horizontal shaft 72 to rotate, and then transmit the power to the lifting screw 74 by means of the bevel gear set 73. A support seat for installing the lifting screw 74 is provided on the mounting base 6, and both ends of the lifting screw 74 are rotatably connected to the support seat, and lifting nuts 11 are respectively provided on the outer walls of both sides of the mounting box 1 to rotate with the lifting screw 74. The rotation of the lifting screw 74 drives the mounting box 1 and the internal telescopic arm 8 and the cleaning scraper arm 9 to move up and down.

[0057] Furthermore, the top wall of the installation box 1 protrudes outwardly from the corresponding side wall of the installation box 1 . When the installation box 1 moves down into the installation base 6 , the top wall of the installation box 1 can cover the upper opening of the installation base 6 .

[0058] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, which includes a telescopic arm swinging and sliding structure. The above vehicle uses the telescopic arm swinging and sliding structure to drive the sliding shaft seat 4 to move axially along the translation screw 2, or drives the telescopic arm 8 to swing horizontally around the sliding shaft seat 4 to extend outward from the installation box 1, thereby realizing the external rotation and translation of the telescopic arm 8, simplifying the structural design, facilitating the processing and installation of the structure, and meeting different driving requirements for the telescopic arm 8.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
