DETAILED DESCRIPTION

[0034] The following is combined with Figure 2-5, the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0035] The present application discloses a car washing machine with a winding structure:

[0036] Reference Figure 2-Figure 5 A car washing machine with a winding structure includes a cart frame 1, a high-pressure water pump 2 is fixed on the cart frame 1, a battery 3 is fixed on the high-pressure water pump 2, the battery 3 is used to power the high-pressure water pump 2, a charging line 31 with a plug is fixed on the battery 3, and a storage box 4 and a winding mechanism 5 are also included. A rotating shaft 11 is rotatable on the cart frame 1, and walking wheels 12 are coaxially fixed at both ends of the rotating shaft 11. The storage box 4 is fixed on the cart frame 1, and the winding mechanism 5 includes a driving assembly 51, a fixed shaft 52 and a first sleeve 53. The fixed shaft 52 is fixed in the storage box 4, and the first sleeve 53 is sleeved and rotated on the fixed shaft 52. The driving assembly 51 is used to drive the first sleeve 53 to rotate. An inlet 42 and an outlet 41 are opened on the inner wall of the storage box 4, and the end of the charging line 31 away from the battery 3 enters the storage box 4 from the inlet 42, then winds around the first sleeve 53 at least once, and finally extends out from the outlet 41. The operator can recycle the charging cable 31 by winding the charging cable 31 around the first sleeve 53 and then driving the first sleeve 53 to rotate through the driving assembly 51. The design of the storage box 4 and the winding mechanism 5 can be used to store the long charging cable 31, avoiding the small and cramped charging range caused by the short charging cable 31.

[0037] Reference Figure 2-Figure 5 The high-pressure water pump 2 is designed with a water inlet hole 21 and a water outlet hole 22. The water inlet hole 21 is used to connect to the water inlet pipe and extract liquid through the water inlet pipe. The water outlet hole 22 is used to connect to the high-pressure water gun to spray water outward. A hook 13 is also fixed on the cart frame 1 for hanging the high-pressure water gun.

[0038] Reference Figure 2-Figure 5 The driving assembly 51 includes a movable part 511, a second sleeve 512, and a transmission belt 513. The second sleeve 512 is sleeved and rotated on the fixed shaft 52. One end of the fixed shaft 52 extends out of the storage box 4. The transmission belt 513 is located outside the storage box 4 and is wound around the second sleeve 512 and the rotating shaft 11. The first sleeve 53 is coaxially arranged with the second sleeve 512. The first sleeve 53 slides on the fixed shaft 52 along the length direction of the fixed shaft 52. The movable part 511 is used to control the movement of the first sleeve 53 on the fixed shaft 52. When the operator pulls the vehicle backward, the rotating shaft 11 drives the second sleeve 512 to rotate through the transmission belt 513, and the first sleeve 53 is driven to be clamped on the second sleeve 512 through the movable part 511. The first sleeve 53 is driven to rotate through the rotation of the second sleeve 512, so that the charging cable 31 is stored back in the storage box 4.

[0039] Reference Figure 2-Figure 5 The end of the first sleeve 53 facing the second sleeve 512 is in the shape of a cone 531, and the end of the second sleeve 512 facing the first sleeve 53 is provided with a cone groove 5121 that matches the end of the second sleeve 512, and the inner wall of the cone groove 5121 is covered with an anti-skid rubber pad 5122. When the cone 531 on the first sleeve 53 abuts against the cone groove 5121 of the second sleeve 512, the second sleeve 512 can drive the first sleeve 53 to rotate, and the design of the anti-skid rubber pad 5122 increases the friction between the first sleeve 53 and the second sleeve 512. At the same time, by designing the separation connection between the first sleeve 53 and the second sleeve 512, it is avoided that the second sleeve 512 drives the first sleeve 53 to rotate during movement, resulting in the disconnection of the charging cable 31.

[0040] Reference Figure 2-Figure 5 Two wire baffles 532 are coaxially mounted and fixed on the first sleeve 53, and the wound charging cable 31 on the fixed shaft 52 is located between the two wire baffles 532. The design of the wire baffles 532 reduces the possibility of the charging cable 31 being tangled due to the random movement of the charging cable 31 when the charging cable 31 is stored. A clamp 43 is fixed at the inlet 42 of the storage box 4 with screws, and the clamp 43 is used to tighten the charging cable 31 at the inlet 42. The clamp 43 fixes the charging cable 31 at the inlet 42 to the inlet 42 to prevent the charging cable 31 wrapped around the first sleeve 53 from being completely pulled out when the charging cable 31 is pulled.

[0041] Reference Figure 2-Figure 5 The movable part 511 includes a spring 5111, a movable block 5112, a toggle rod 5113 and a locking piece 5114. The movable block 5112 is sleeved and slid on the fixed shaft 52 along the length direction of the fixed shaft 52. The movable block 5112 is located on the side of the first sleeve 53 away from the second sleeve 512. The first sleeve 53 rotates on the movable block 5112. The two ends of the spring 5111 respectively abut against the movable block 5112 and the inner wall of the storage box 4. The spring 5111 always drives the movable block 5112 to move toward the side away from the first sleeve 53; one end of the toggle rod 5113 is fixed on the movable block 5112, and a movable groove 45 is provided on one side of the outlet 41 of the storage box 4. The other end of the toggle rod 5113 passes through the movable groove 45 and extends out of the storage box 4. The locking piece 5114 is used to lock the position of the toggle rod 5113 when the first sleeve 53 is away from the second sleeve 512. The movable block 5112 is driven by the toggle rod 5113 to push the first sleeve 53 toward the direction of abutting the second sleeve 512, and then the position of the toggle rod 5113 is locked by the locking piece 5114 so that the first sleeve 53 can be clamped and fixed on the second sleeve 512 and driven to rotate by the second sleeve 512. When the unlocked locked state is reached, the spring 5111 drives the movable block 5112 and further drives the first sleeve 53 away from the second sleeve 512.

[0042] Reference Figure 2-Figure 5 The limited rotation column 44 is fixed on the inner wall of the storage box 4. The limited rotation column 44 is located on the side of the movable block 5112 away from the first sleeve 53. The movable block 5112 is provided with a limited rotation hole 5117 for the limited rotation column 44 to pass through. The first sleeve 53 is provided with a limited rotation ring groove 533 on the side facing the limited rotation column 44. The limited rotation column 44 and the limited rotation ring groove 533 are interference fit. When the limited rotation column 44 is inserted into the limited rotation ring groove 533, the first sleeve 53 is away from the second sleeve 512. When the first sleeve 53 is away from the second sleeve 512, the limited rotation column 44 is inserted into the limited rotation ring groove 533 through the limited rotation hole 5117 and is interference fit therewith, so as to reduce the self-rotation of the first sleeve 53 when moving. At the same time, the limited rotation column 44 is chamfered on the side close to the first sleeve 53, and the chamfer is used to facilitate the insertion of the limited rotation column 44 into the limiting hole. The interference fit between the rotation-limiting post 44 and the rotation-limiting ring groove 533 can only limit the self-rotation of the first sleeve 53. The user can still pull the charging cable 31 out of the storage box 4.

[0043] Reference Figure 2-Figure 5 The locking member 5114 includes an insertion rod 5115 and two sockets 5116 with insertion holes. The sockets 5116 are fixed to the storage box 4. The two sockets 5116 are respectively located on both sides of the movable groove 45. When the insertion rod 5115 is inserted into the two insertion holes and the toggle rod 5113 moves to abut against the insertion rod 5115, the first sleeve 53 abuts against the second sleeve 512. When the cone 531 of the first sleeve 53 is clamped in the cone groove 5121 of the second sleeve 512, the operator limits the movement of the toggle rod 5113 by inserting the insertion rod 5115, thereby limiting the movement of the movable block 5112.

[0044] Reference Figure 2-Figure 5 , and also includes a cover 6 and two baffles 7, the baffles 7 are vertically fixed on both sides of the cart frame 1, and the two ends of the cover 6 are respectively connected to the upper ends of the two baffles 7 by bolts, and the cover 6 and the two baffles 7 together form a protection space, and the high-pressure water pump 2, the battery 3, the winding mechanism 5 and the storage box 4 are all located in the protection space. The design of the cover 6 and the baffles 7 can be used to protect the high-pressure water pump 2, the battery 3, the winding mechanism 5 and the storage box 4 fixed inside, and the ventilated protection space at both ends is also convenient for the high-pressure water pump 2 to dissipate heat.

[0045] Reference Figure 2-Figure 5 The storage box 4 is hinged with a door panel on the side, and the door panel is used to facilitate the operator to wind the charging line 31. After the charging line 31 extends from the outlet 41, the operator installs a charging plug on it.
