In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0038] Reference Figures 1 to 4 ,as well as Fig.10 The present invention provides a squeezing device, which is used to squeeze a drying cloth 1003 to squeeze out the moisture in the drying cloth 1003. The squeezing device includes a bracket 101, a first driving mechanism 102, a second driving mechanism 105 and a squeezing assembly 1002, wherein the first driving mechanism 102 and the second driving mechanism 105 are both mounted on the bracket 101. The squeezing assembly 1002 is used to clamp the drying cloth 1003, the second driving mechanism 105 is used to drive the squeezing assembly 1002 to clamp or release the drying cloth 1003, and the first driving mechanism 102 is used to drive the squeezing assembly 1002 to move, so as to drive the squeezing assembly 1002 to move, thereby changing the position of the drying cloth 1003 clamped by the squeezing assembly 1002.

[0039] Reference Fig.10 The extrusion assembly 1002 includes a first extrusion member 107 and a second extrusion member 1001. The second driving mechanism 105 is used to drive the first extrusion member 107 and the second extrusion member 1001 to move closer to or farther from each other. When the distance between the first extrusion member 107 and the second extrusion member 1001 is small enough, the first extrusion member 107 and the second extrusion member 1001 can clamp (or squeeze) the drying cloth 1003 together; when the distance between the first extrusion member 107 and the second extrusion member 1001 is large, the first extrusion member 107 and the second extrusion member 1001 will release the drying cloth 1003, and the dried drying cloth 1003 can leave the working area of ​​the extrusion assembly 1002. The second driving mechanism 105 can be configured to simultaneously drive the first extrusion member 107 and the second extrusion member 1001 to move relative to the bracket 101; the second driving mechanism 105 can also be configured to only drive a portion of the extrusion assembly 1002 to move relative to the bracket 101, for example, the second driving mechanism 105 drives the first extrusion member 107 to move relative to the bracket 101, while the second extrusion member 1001 is stationary relative to the bracket 101.

[0040] In addition, the specific forms of the first extrusion member 107 and the second extrusion member 1001 can also be configured in a variety of ways. For example, the first extrusion member 107 and the second extrusion member 1001 are both configured as rollers, or both are configured as plates, or both are configured as block components, or, as Fig.10 As shown, the first extrusion member 107 is configured as a roller, and the second extrusion member 1001 is configured as a plate member (combined with Figure 4 and Fig.10 , the second extrusion member 1001 is spaced apart from the rear side of the bracket 101). The feasible arrangement modes are not listed here one by one.

[0041] by Fig.10For example, the general operation process of the squeezing device is as follows: after the drying cloth 1003 moves to between the first squeezing member 107 and the second squeezing member 1001, the squeezing assembly 1002 clamps the drying cloth 1003, and then the squeezing assembly 1002 moves under the action of the first driving mechanism 102, and gradually squeezes the drying cloth 1003 from top to bottom; finally, the squeezing assembly 1002 is released, and the squeezed drying cloth 1003 leaves the working area of ​​the squeezing assembly 1002, and the next batch of drying cloth 1003 to be squeezed enters the working area of ​​the squeezing assembly 1002. In addition, the squeezing assembly 1002 can also be moved up and down and back and forth multiple times while maintaining the clamping effect on the drying cloth 1003, so as to fully squeeze out the water in the drying cloth 1003, and then the squeezing assembly 1002 is released. In the squeezing device provided by the present invention, after the squeezing component 1002 clamps the drying cloth 1003, the squeezing component 1002 can move and change the position where the drying cloth 1003 is squeezed, which is beneficial to reducing the area of ​​the drying cloth 1003 where water is not squeezed out, and improving the squeezing effect of the drying cloth 1003.

[0042] In some embodiments, the squeezing device also has the function of cleaning the drying cloth 1003. The squeezing device first cleans the drying cloth 1003 and then squeezes the drying cloth 1003. The drying cloth 1003 is cleaner after the treatment, and the car can be prevented from being soiled by the drying cloth 1003 during the process of drying the car. Figure 6 The drying module includes a liquid spraying element 106, which is used to spray at least one of water and cleaning liquid to the drying cloth 1003. If the degree of dirtiness of the drying cloth 1003 is low, only water spraying can be considered. Figure 6 As shown, the liquid spraying member 106 can be configured as a pipe member having a plurality of spray holes 601, or can be configured as a nozzle. It should be noted that although the water in the drying cloth 1003 will increase during the cleaning process, during the squeezing process, the water added during the cleaning process will be squeezed out together with the water absorbed when drying the car.

[0043] In some embodiments, the liquid spraying member 106 can move to change the position where the drying cloth 1003 is sprayed with water or cleaning liquid, thereby reducing the blind area of ​​the drying cloth 1003. The liquid spraying member 106 can be directly driven by the first driving mechanism 102 to move, thereby saving the number of driving mechanisms and parts in the squeezing device and saving costs. To further illustrate the situation where the liquid spraying member 106 is driven by the first driving mechanism 102, the specific structure of the first driving mechanism 102 is first introduced below.

[0044] Reference Figure 6 and Figure 7In some embodiments, the first driving mechanism 102 includes a driving motor 603, a first sprocket 602, a second sprocket 502 and a first chain 103. The squeezing device also includes a mounting platform 703, which is slidably connected to the bracket 101, and the first extrusion member 107 and the second driving mechanism 105 are both mounted on the mounting platform 703. The driving motor 603 is mounted on the bracket 101, the first sprocket 602 is connected to the output shaft of the driving motor 603, the second sprocket 502 is rotatably connected to the bracket 101, and the first sprocket 602 and the second sprocket 502 are spaced apart along the sliding direction of the mounting platform 703. The first chain 103 is simultaneously surrounded by the periphery of the first sprocket 602 and the second sprocket 502, and the first sprocket 602 and the second sprocket 502 are both meshed with the first chain 103. In addition, the mounting platform 703 is fixedly connected to the first chain 103. When the driving motor 603 rotates, the first sprocket 602 rotates, the first chain 103 moves and drives the mounting platform 703 to move, and the first extrusion member 107 and the second driving mechanism 105 also move accordingly. This type of first driving mechanism 102 has a strong load-bearing capacity and a large power transmission, and is suitable for the case where the first extrusion member 107 needs to move a long distance (suitable for the case where the drying cloth 1003 is long).

[0045] In other embodiments, when the first extrusion member 107 needs to move a short distance, the first driving mechanism 102 can also be adjusted to the following form: the mounting platform 703 is driven to rise and fall by a cylinder, a hydraulic cylinder or a screw slider mechanism.

[0046] In addition, refer to Figure 3 , Figure 6 and Fig. 9 In some embodiments, the first driving mechanism 102 further includes a counterweight block 108 and a connecting member, and the two ends of the connecting member are respectively connected to the counterweight block 108 and the mounting platform 703. The connecting member can be set as a chain (referred to as the second chain 104), and accordingly, the first driving mechanism 102 further includes a third sprocket 501. Figure 5 and Figure 6 The third sprocket 501 is rotatably connected to the bracket 101, and the third sprocket 501 is located above the mounting platform 703; the second chain 104 is meshed with the third sprocket 501, the counterweight 108 is connected to one end of the second chain 104, and the other end of the second chain 104 passes around the third sprocket 501 from bottom to top and is fixed to the mounting platform 703. Fig.10 The sum of the weight of the mounting platform 703 and the components on the mounting platform 703 is close to the weight of the counterweight 108 (not necessarily strictly equal to the weight of the counterweight 108 in consideration of factors such as friction), and the counterweight 108 can prevent the mounting platform 703 from falling uncontrollably. Fig.10, the sum of the weights of the mounting platform 703 and the components on the mounting platform 703 can be partially offset by the weight of the counterweight 108, so the resistance that the driving motor 603 needs to overcome when driving the mounting platform 703 to move is small, and accordingly, the power consumption of the driving motor 603 is small, and the energy consumption of the squeezing device is low; or, when designing and selecting, a motor with a smaller rated power can be selected as the driving motor 603, which is conducive to reducing the cost of the squeezing device. In other embodiments, the connecting member can be set as a rope, and accordingly, the third sprocket 501 can be replaced by a fixed pulley.

[0047] When the liquid spraying member 106 is driven by the first driving mechanism 102, the liquid spraying member 106 can be fixedly connected to the first chain 103, and the liquid spraying member 106 will also move when the first chain 103 moves. In some embodiments, the liquid spraying member 106 and the mounting platform 703 are located on different sides of the first chain 103, and accordingly, the movement directions of the mounting platform 703 and the liquid spraying member 106 are opposite, and the liquid spraying member 106 rises when the mounting platform 703 descends, and the liquid spraying member 106 descends when the mounting platform 703 rises. Figure 3 and Figure 4 The liquid spraying member 106 is connected to the front side of the first chain 103 , and the mounting platform 703 is connected to the rear side of the first chain 103 .

[0048] The advantage of this arrangement is that when the squeezing assembly 1002 squeezes out some of the drying cloths 1003, the liquid spraying part 106 cleans other drying cloths 1003 (this batch of drying cloths 1003 is the drying cloths 1003 that are about to enter the working area of ​​the squeezing assembly 1002), and the working efficiency of the squeezing device is higher. Accordingly, other drying cloths 1003 should first pass through the liquid spraying part 106, and then the drying cloths 1003 bypass the bracket and pass through the squeezing assembly 1002. If the liquid spraying part 106 and the mounting platform 703 are connected to the same side of the chain, then, for the drying cloths 1003 entering the working area of ​​the squeezing assembly 1002, the squeezing assembly 1002 needs to wait for the liquid spraying part 106 to clean the drying cloths 1003 before the squeezing assembly 1002 can move. The working interval of the squeezing assembly 1002 is long, and the working efficiency of the squeezing device is relatively low.

[0049] The structure of the second driving mechanism 105 is described below. Figure 7 and Figure 8 In some embodiments, the second driving mechanism 105 includes a driving cylinder 702 and a connecting rod 701. The cylinder body 704 of the driving cylinder 702 is rotatably connected to the mounting platform 703, the end of the piston rod 705 of the driving cylinder 702 is connected to the connecting rod 701, one end of the connecting rod 701 is rotatably connected to the mounting platform 703, and the other end of the connecting rod 701 is connected to the first extrusion member 107. Figure 7From the left view, when the piston rod 705 is extended, the connecting rod 701 rotates clockwise, and the first extrusion member 107 approaches the second extrusion member 1001; when the piston rod 705 is retracted, the connecting rod 701 rotates counterclockwise, and the first extrusion member 107 moves away from the second extrusion member 1001.

[0050] The present invention also provides a car washing machine, which comprises the squeezing device. The car washing machine integrates the function of squeezing the drying cloth, and the degree of automation of car washing is high.

[0051] The present invention also provides a squeezing method, referring to Fig.11 , the squeezing method comprises the following steps:

[0052] S10: conveying the drying cloth 1003 to be squeezed to the squeezing assembly 1002;

[0053] S20: The squeezing assembly 1002 clamps the drying cloth 1003;

[0054] S30: The pressing assembly 1002 moves while maintaining the clamping state of the drying cloth 1003 .

[0055] This method can be used to squeeze the drying cloth 1003 quickly and efficiently. In some embodiments, the squeezing method further includes the following steps: before the drying cloth 1003 is transported to the working area of ​​the squeezing assembly 1002, the drying cloth 1003 is first cleaned (rinsed). This can make the drying cloth 1003 cleaner and prevent the drying cloth 1003 from dirtying the car. More specifically, while the squeezing assembly 1002 squeezes the drying cloth 1003, the liquid spraying member 106 cleans the next batch of drying cloths 1003 to be squeezed, which can shorten the working interval of the squeezing assembly 1002, thereby improving the working efficiency of the squeezing device.

[0056] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
