Description

Technical Field

[0001] This application relates to the field of car washing technology, specifically to vehicle tailgate, vehicle rear drying methods, automatic car wash drying methods and equipment. Background Technology

[0002] Automated car wash services use car wash robots to clean dirt from vehicle surfaces, including a drying process. The tailgate of SUVs, MPVs, and other similar vehicles is typically located on the upper edge of the tailgate, forming a semi-enclosed tailgate cavity with a rearward opening. When drying the tailgate, airflow enters the tailgate cavity through this opening, easily creating localized backflow and vortex zones. This causes liquid to circulate and rotate within the tailgate cavity, making it difficult for liquid to effectively detach, resulting in excessive residual water inside. Summary of the Invention

[0023] Based on one of the above objectives, some embodiments of this application provide a method for drying the rear flap of a vehicle using an automatic car wash device. The automatic car wash device includes a motion mechanism, a drying component, an air supply drive component, and a control component.

[0024] Based on one of the above objectives, some embodiments of this application provide an automatic car wash drying method applied to an automatic car wash equipment. The automatic car wash equipment includes a motion mechanism, a drying component, an air supply drive component, and a control component. The drying component is disposed on the motion mechanism and has an air outlet for blowing air onto the vehicle being washed. The air supply drive component is used to deliver airflow to the air outlet. Both the motion mechanism and the air supply drive component are connected to the control component. The control component controls the motion mechanism to drive the drying component to move relative to the vehicle and controls the air supply drive component to deliver air to the air outlet to perform the drying operation. The upper end of the rear windshield of the vehicle has a tailgate cavity with an opening facing away from the front of the vehicle and the tailgate cavity extends along the width direction of the vehicle. Automatic car wash drying methods applied to automatic car wash equipment include: The motion mechanism is controlled to drive the drying component to move from the front of the vehicle to the rear of the vehicle to perform a drying operation on the vehicle. During the movement of the drying component from the front of the vehicle to the rear of the vehicle, the rear of the vehicle is dried using the vehicle rear drying method applied to automatic car wash equipment as described in any of the above embodiments.

[0025] To achieve one of the above objectives, some embodiments of this application provide an automatic car wash device, including: A car wash device for washing vehicles; A drying assembly having an air outlet for blowing air onto the vehicle being cleaned; A motion mechanism is provided, wherein the drying component is disposed in the motion mechanism, and the motion mechanism is used to drive the drying component to move; An air supply drive assembly, the air supply drive assembly being used to deliver airflow to the air outlet; The system includes a control component, wherein the motion mechanism and the air delivery drive component are both connected to the control component.

The drying component is moved by the control motion mechanism, changing the position of the drying component blowing towards the rear end cavity in the vehicle width direction. This makes it less likely for eddies to form in the rear end cavity, and the liquid inside the rear end cavity is less likely to swirl within it, thus making it easier for the airflow blown in by the drying component to carry it away, improving the drying effect on the rear end. Furthermore, after the rear end drying operation, by moving the air outlet towards the rear windshield from the upper end to the lower end of the rear windshield, the liquid on the rear windshield can be blown downwards, preventing secondary contamination of the rear end cavity.

[0037] Current automatic car wash drying methods often create localized vortex zones within the tailgate cavity when airflow enters through an opening during vehicle rear drying. This causes liquid to circulate and rotate within the tailgate cavity, making it difficult for the liquid to effectively escape. In some embodiments of this application, the vehicle rear drying method changes the position of the drying assembly blowing air into the tailgate cavity in the vehicle's width direction. This prevents the formation of vortex zones within the tailgate cavity, making it easier for the liquid to be carried away by the airflow blown in by the drying assembly.

[0038] To facilitate understanding of the vehicle rear drying method, we will first introduce the automatic car wash equipment used to wash vehicles.

[0039] In some embodiments, please refer to Figures 1 to 3The automatic car wash equipment includes a motion mechanism, a drying assembly 1, an air supply drive assembly, and a control assembly. The drying assembly 1 is located within the motion mechanism and has an air outlet 11 for blowing air onto the vehicle 2. The air supply drive assembly delivers airflow to the air outlet 11. Both the motion mechanism and the air supply drive assembly are connected to the control assembly. The control assembly controls the motion mechanism to move the drying assembly 1 relative to the vehicle 2. The control assembly also controls the air supply drive assembly to deliver air to the air outlet 11 to perform the drying operation. In some embodiments, the control assembly includes a programmable logic controller (such as a PLC).

[0040] Regarding the air-drying assembly 1, as the terminal component for drying the vehicle 2, in some embodiments, the air-drying assembly 1 includes a housing, a mounting structure for mounting the housing, and an airflow duct formed within the housing. The end of the airflow duct forms the air outlet 11 of the air-drying assembly 1. The air outlet 11 of the air-drying assembly 1 is the opening where the airflow leaves the air-drying assembly 1. In some embodiments, to improve the drying effect, the air outlet 11 increases the airflow velocity and dynamic pressure by reducing the air outlet cross-sectional area, thereby improving the effect of blowing away water droplets adhering to the vehicle 2 and reducing water residue.

[0041] Regarding the form of the drying assembly 1 and the air supply drive assembly, in some embodiments, the drying assembly 1 and the air supply drive assembly are integrated together to form a fan. This fan can be either an axial flow fan or a centrifugal fan. In other embodiments, the drying assembly 1 and the air supply drive assembly are arranged separately. For example, the drying assembly 1 and the air supply drive assembly are connected by a flexible hose, wherein the drying assembly 1 is mounted on a moving mechanism, and the air supply drive assembly is mounted on a fixed bracket, allowing the drying assembly 1 to move relative to the air supply drive assembly. The air supply drive assembly includes an air compressor and an air tank, which supplies air to the drying assembly 1.

[0042] The motion mechanism serves as the mechanical support and moving platform for the drying assembly 1. In some embodiments (not shown), the motion mechanism includes a moving mechanism that moves along the length of the vehicle 2. The moving mechanism includes a moving frame and a moving frame drive mechanism, with the drying assembly 1 mounted on the moving frame. The moving frame drive mechanism can employ a drive motor and rack and pinion mechanism as in the prior art, or it can use drive wheels and guide wheels to drive the moving frame on a track, or it can use a drive motor and chain to drive the moving frame. In some embodiments, the motion mechanism also includes a movable arm and a movable arm drive mechanism that drives the movable arm. Both the movable arm and the movable arm drive mechanism are mounted on the moving frame, and the drying assembly 1 is mounted at the end of the movable arm. The movable arm can change the position and orientation of the drying assembly 1 according to the shape of the vehicle 2. For example, the moving frame can be a gantry frame. In a gantry reciprocating automatic car wash system, the drying assembly 1 is mounted on the crossbeam of the gantry frame, and the moving frame drive mechanism includes a walking system that drives the entire crossbeam to move back and forth along the track.

[0043] In some embodiments, the automatic car wash equipment further includes a car wash chamber and a car wash device. The car wash device serves as a front-end actuator for removing dirt from the vehicle body and is used to wash the vehicle 2 located in the car wash area within the car wash chamber. In some embodiments, the car wash device and the drying assembly 1 share a common motion mechanism. For example, both the water spray assembly and the drying assembly 1 of the car wash device are mounted on a movable frame. When washing the vehicle 2, under the control of the control component, the water spray assembly sprays water, and the drying assembly 1 stops blowing air. When drying the vehicle 2, under the control of the control component, the air supply drive assembly delivers airflow to the drying assembly 1, and the water spray assembly stops spraying water. Of course, in some embodiments, the car wash device and the drying assembly 1 may each have independent motion mechanisms.

[0044] To accommodate different airflow directions, in some embodiments, the motion mechanism includes an angle adjustment mechanism for adjusting the airflow direction D1 of the air outlet 11. A control component is connected to the angle adjustment mechanism to control it. The control component controls the airflow direction D1 of the air outlet 11 by controlling the angle adjustment mechanism.

[0045] For example, the angle adjustment mechanism is used to drive the drying assembly 1 to rotate as a whole, and the angle adjustment mechanism is mounted on the moving mechanism, while the drying assembly 1 is mounted on the angle adjustment mechanism. For example, the moving mechanism can be a linear drive mechanism such as a gear and rack mechanism, a lead screw and nut mechanism, or a belt conveyor mechanism driven by a drive motor. The angle adjustment mechanism can be an angle adjustment motor that drives the drying assembly 1 to rotate as a whole.

[0046] In some embodiments, the drying assembly 1 includes a housing and an air vent assembly disposed on the housing. The air vent assembly is rotatably mounted on the housing, and an angle adjustment mechanism is used to drive the air vent assembly to rotate relative to the housing, thereby adjusting the air outlet direction D1 of the air outlet 11. For example, the angle adjustment mechanism includes an angle adjustment motor and a gear train. The gear train is connected to the air vent assembly, and the angle adjustment motor drives the air vent assembly to rotate via the gear train. Of course, in addition to driving the air vent assembly via a gear train, the angle adjustment mechanism can also use an angle adjustment motor directly connected to the air vent assembly to drive the air vent assembly to rotate.

[0047] To facilitate understanding of the vehicle rear drying method, the structure of the vehicle's rear flap is described below.

[0048] Please refer to Figures 1 to 3 The rear spoiler 21 of vehicle 2 is also called the rear diffuser. The rear spoiler 21 is typically installed on the top of the tailgate or the rear edge of the roof of an SUV or hatchback. It improves the vehicle's stability and handling by optimizing the airflow separation point at the rear of the vehicle and reducing air lift at high speeds. Additionally, the rear spoiler 21 also serves to guide rainwater and reduce dust accumulation on the rear window.

[0049] A rear end cavity 22 is formed on the lower side of the rear end 21, and the rear end cavity 22 is located at the upper end of the rear windshield 23. The rear end cavity 22 extends along the width direction of the vehicle 2, that is, the rear end cavity 22 is an elongated cavity extending along the width direction of the vehicle. The rear end cavity 22 has an opening 221 facing away from the front of the vehicle 2, that is, the opening 221 faces the rear of the vehicle 2. In some embodiments, the front side edge 211 of the rear end 21 is connected to the top of the tailgate or the rear edge of the roof, so that the front side of the rear end cavity 22 is closed, and the rear side edge 212 of the rear end 21 is suspended, forming the opening 221 of the rear end cavity 22 between the rear side edge 212 of the rear end 21 and the tailgate.

[0050] In some embodiments, a method for drying the rear of a vehicle applied to an automatic car wash includes: The air supply drive component is controlled to deliver airflow to the air outlet 11 of the air drying component 1; The air outlet 11 of the air drying assembly 1 is controlled to blow air toward the opening 221 of the tailgate cavity 22, and the motion mechanism is controlled to drive the air drying assembly 1 to change the position of the air drying assembly 1 blowing air toward the tailgate cavity 22 in the width direction of the vehicle 2. The control motion mechanism drives the air drying component 1 to move, so that the position of the air outlet 11 blowing towards the rear windshield 23 moves from the upper end of the rear windshield 23 to the lower end of the rear windshield 23.

[0051] In some embodiments, the vehicle rear drying method applied to an automatic car wash equipment includes a rear end drying method for performing a drying operation on the rear end 22. The rear end drying method includes performing a drying operation on the rear end 22 by controlling an air supply drive assembly to deliver airflow to an air outlet 11, controlling the air outlet 11 of the drying assembly 1 to blow air toward the opening 221 of the rear end cavity 22, and controlling a motion mechanism to drive the drying assembly 1 to change the position of the drying assembly 1 blowing air toward the rear end cavity 22 in the width direction of the vehicle 2.

[0052] In some embodiments, the vehicle rear drying method applied to automatic car wash equipment includes a rear windshield drying method for drying the rear windshield 23. The rear windshield drying method includes: controlling an air supply drive assembly to deliver airflow to an air outlet 11; and controlling a motion mechanism to move a drying assembly 1, causing the position of the air outlet 11 blowing air onto the rear windshield 23 to move from the upper end to the lower end of the rear windshield 23. In some embodiments, the rear windshield drying method in this application is performed after the rear spoiler 22 has been dried.

[0053] Please refer to Figures 1 to 3The following describes the method for drying the rear spoiler: The air supply drive assembly is controlled to deliver airflow to the air outlet 11. The air outlet 11 of the drying assembly 1 is controlled to blow air towards the opening 221 of the rear spoiler cavity 22. The motion mechanism is controlled to move the drying assembly 1 to change the position of the drying assembly 1 blowing air towards the rear spoiler cavity 22 in the width direction of the vehicle 2. It can be understood that the position of the drying assembly 1 blowing air towards the rear spoiler cavity 22 in the width direction of the vehicle 2 refers to the position within the rear spoiler cavity 22 opposite to the air outlet 11, that is, the position where the airflow blowing directly from the air outlet 11 reaches without being obstructed or changing direction. The width direction of the vehicle 2 refers to the left-right direction.

[0054] The principle of the tailgate drying method will be explained below with reference to the accompanying drawings. The inventors discovered that in current automatic car wash drying methods, although airflow can enter the tailgate cavity 22, a large amount of residual liquid remains in the tailgate cavity 22 after drying. This residual liquid flows down the tailgate of the vehicle 2 to the rear windshield 23, forming water stains. In solving this problem, the inventors found that even if the air outlet 11 of the drying component 1 blows directly onto the tailgate cavity 22, the problem cannot be effectively solved. The inventors creatively directed the air outlet 11 of the drying component 1 towards the opening 221 of the tailgate cavity 22 and changed the position of the drying component 1 blowing air onto the tailgate cavity 22 in the width direction of the vehicle 2. This airflow method reduces the vortex area within the tailgate cavity 22. During the air drying assembly 1 blowing air into the tailgate cavity 22, due to the change in the position of the air drying assembly 1 blowing towards the tailgate cavity 22 in the width direction of the vehicle 2, at least a portion of the residual liquid in the tailgate cavity 22 can migrate along the width direction of the vehicle 2 and be carried away from the tailgate cavity 22 by the airflow from both ends in the length direction (i.e., the width direction of the vehicle). Therefore, in the method of air drying the tailgate of the vehicle in this application, the liquid in the tailgate cavity 22 is more easily carried away by the airflow blown in by the air drying assembly 1, solving the problem that the residual liquid in the tailgate cavity 22 is not easily blown out.

[0055] Regarding the movement of the drying component 1 during the drying process of the tail flap, please refer to some embodiments. Figures 1 to 3 The control of the motion mechanism to drive the drying component 1 to change the position of the drying component 1 blowing towards the tailgate cavity 22 in the width direction of the vehicle 2 includes: controlling the motion mechanism to drive the drying component 1 to reciprocate and translate along the width direction of the vehicle 2 to change the position of the drying component 1 blowing towards the tailgate cavity 22 in the width direction of the vehicle 2.

[0056] During the reciprocating translation of the drying component 1 along the width direction of the vehicle 2, in some embodiments, please refer to... Figures 1 to 3 During the drying process of the tail rim 21, the posture of the drying component 1 remains unchanged relative to the vehicle 2, so that the air outlet 11 of the drying component 1 maintains the same air outlet direction D1 relative to the vehicle 2.

[0057] Of course, as an alternative, during the reciprocating translation of the air drying assembly 1 along the width direction of the vehicle 2, the air outlet 11 of the air drying assembly 1 can also be changed as needed. For example, in some embodiments, controlling the motion mechanism to drive the air drying assembly 1 to reciprocate along the width direction of the vehicle 2 includes: when the motion mechanism drives the air drying assembly 1 to move to the left side of the vehicle 2, controlling the air outlet 11 of the air drying assembly 1 to tilt to the left side of the vehicle 2, that is, the air outlet 11 blows air towards the left front of the vehicle 2, which is more conducive to at least part of the residual liquid in the tailgate cavity 22 being discharged from the left end of the tailgate cavity 22. Similarly, in some embodiments, controlling the motion mechanism to drive the drying component 1 to reciprocate along the width direction of the vehicle includes: when the motion mechanism drives the drying component 1 to move to the right side of the vehicle 2, controlling the air outlet 11 of the drying component 1 to tilt the air outlet direction D1 to the right side of the vehicle 2, that is, the air outlet 11 blows air towards the right front of the vehicle 2, which is more conducive to at least part of the residual liquid in the tailgate cavity 22 being discharged from the right end of the tailgate cavity 22.

[0058] In the process of drying the tailgate, in addition to the method of reciprocating the drying component 1, as an alternative method, in some embodiments not shown, controlling the motion mechanism to drive the drying component 1 to change the position of the drying component 1 blowing towards the tailgate cavity 22 in the width direction of the vehicle 2 includes: controlling the motion mechanism to drive the drying component 1 to swing back and forth in the width direction of the vehicle 2 to change the position of the drying component 1 blowing towards the tailgate cavity 22 in the width direction of the vehicle 2.

[0059] Of course, in some embodiments, in the tail-end air-drying method, the motion mechanism can also drive the air-drying component 1 to alternately perform translational motion and reciprocating oscillation, or it can simultaneously perform reciprocating oscillation during the translational process of the air-drying component 1.

[0060] During the drying process of the rear end, there are several feasible examples regarding the method of changing the position of the drying component 1 blowing towards the rear end cavity 22 in the width direction of the vehicle 2: For example, in some embodiments, the position of the drying component 1 blowing towards the tailgate cavity 22 varies uniformly. Exemplarily, during the drying of the tailgate 21, the control motion mechanism drives the drying component 1 to continuously reciprocate along the width direction of the vehicle 2, i.e., the drying component 1 continuously translates at a constant speed. Exemplarily, during the drying of the tailgate 21, the control motion mechanism causes the drying component 1 to continuously oscillate back and forth, with the drying component 1 moving continuously at a constant speed.

[0061] For example, in some embodiments, the position of the drying component 1 blowing towards the tailgate cavity 22 changes intermittently. For instance, during the drying process of the tailgate 21, the control motion mechanism drives the drying component 1 to intermittently reciprocate along the width direction of the vehicle 2. The intermittent translational movement of the drying component 1 means that after translating a set distance, it stops for a preset time and then continues to translate.

[0062] For example, during the drying process of the tail rim 21, the control motion mechanism causes the drying component 1 to oscillate intermittently, that is, the intermittent oscillation of the drying component 1.

[0063] During the drying process of the tailgate, regarding the specific motion parameters of the drying component 1 driven by the motion mechanism, in some embodiments, the speed range of the reciprocating translation of the drying component 1 along the width direction of the vehicle 2 is 10-40 cm / s. In other embodiments, the number of reciprocating translations of the drying component 1 along the width direction of the vehicle 2 is controlled to be 3-10 times. It should be noted that the number of translations refers to the number of times the tailgate cavity 22 is blown, and one reciprocating translation movement of the drying component 1 includes two translations. Of course, in some embodiments not shown, the reciprocating translation speed and the number of translations of the drying component 1 can also be adaptively varied as needed. Similarly, in some embodiments, the number of oscillations of the drying component 1 driven by the motion mechanism is controlled to be 3-10 times.

[0064] Taking one of the drying components, 1, as an example, Figure 4 The distance of left-right reciprocating translation of one of the drying components 1 is shown. For some embodiments, please refer to... Figure 4 The motion mechanism drives the drying component 1 to move 30-50cm to the left and 30-50cm to the right relative to the center of the vehicle's width direction. In other words, the left-right reciprocating translation range of the drying component 1 is 30-50cm. Specifically, in some embodiments, the left-right reciprocating translation range of the drying component 1 can be 30cm, 35cm, 40cm, 45cm, or 50cm. The left-right reciprocating translation range of the drying component 1 can also be adjusted as needed; for example, the left-right reciprocating translation range of the drying component 1 can be less than 30cm or greater than 50cm. In comparison, the left-right reciprocating translation range of the air-drying component 1 is within the range of 30-50cm, which can take into account the working space requirements, air-drying efficiency and air-drying effect. When the left-right reciprocating translation range is large, the air blown by the air-drying component can increase the speed at which the residual liquid in the tailgate cavity 22 migrates along the width direction of the vehicle 2, thereby speeding up the discharge of the residual liquid and improving the air-drying effect. However, if the left-right reciprocating translation range is too large, it requires a longer movement time and a larger working space. Conversely, when the left-right reciprocating translation range is small, the air-drying component requires less working space and the time for a single translation is shorter. However, the residual liquid in the tailgate cavity 22 migrates more slowly along the width direction of the vehicle 2, and the discharge efficiency of the residual liquid is reduced.

[0065] In some embodiments, please refer to Figure 5 and Figure 6During the drying process of the tailgate 2, the opening 221 of the tailgate cavity 22 faces the rear of the vehicle 2. A plane perpendicular to the width direction (i.e., left-right direction) of the vehicle 2 is defined as the first plane P1. The air outlet 11's airflow direction D1 towards the opening 221 of the tailgate cavity 22 satisfies the following condition: the projection of the air outlet 11 onto the first plane P1 is the first projection direction D2. The angle α between the first projection direction D2 and the horizontal plane P2 is less than or equal to 45°. This allows a higher proportion of the airflow from the air outlet 11 entering the tailgate cavity 22 through the opening 221, thereby improving the drying effect on the tailgate cavity 22. Specifically, the angle between the first projection direction D2 and the horizontal plane P2 can be 0°, 10°, 15°, 30°, 35°, 40°, or 45°. In some other embodiments not shown, the angle b between the air outlet 11 toward the opening 221 of the taillight cavity 22 and the horizontal plane P2 is less than or equal to 45°.

[0066] Of course, in some embodiments, please refer to Figures 2 to 5 During the drying process of the tail rim 2, the air outlet 11 facing the opening 221 of the tail rim cavity 22 can also be parallel to the first plane P1. At this time, the air outlet direction D1 is the same as the first projection direction D2.

[0067] Specifically, in some embodiments, when the air outlet direction D1 is the same as the first projection direction D2, and the angle between the first projection direction D2 and the horizontal plane P2 is 0°, the air outlet direction D1 of the air outlet 11 towards the opening 221 of the tailgate cavity 22 is a horizontal direction from back to front. That is, the air outlet 11 blows air into the opening 221 of the tailgate cavity 22 with the air outlet direction D1 having an angle of 0 degrees with the horizontal plane P2. In other words, the air outlet 11 blows air from the rear of the vehicle 2 towards the front of the vehicle 2 along the length direction of the vehicle 2 towards the opening 221 of the tailgate cavity 22.

[0068] It should be noted that the angle between the first projection direction D2 and the horizontal plane P2 is less than or equal to 45°, which includes both the case where the air outlet direction D1 is obliquely upward (not shown in the figure) and the case where the air outlet direction D1 is obliquely downward ( Figure 3 (As shown).

[0069] In some embodiments, during the reciprocating translation of the drying assembly 1 along the width direction of the vehicle 2, the air outlet 11 blows air towards the opening 221 of the tailgate cavity 22 as follows: the air outlet 11 blows air into the tailgate cavity 22 along the length direction of the vehicle 2 towards the opening 221 of the tailgate cavity 22, and the air outlet direction D1 of the air outlet 11 remains unchanged during the drying process of the tailgate 21. Of course, as an alternative, in some embodiments, the air outlet 11 may also blow air towards the left front or right front of the vehicle 2.

[0070] It should be noted that, unless otherwise specified, the front, back, left, and right directions described in the embodiments of this application are based on vehicle 2. The front refers to the direction in which vehicle 2 is normally moving, the back refers to the direction in which vehicle 2 is reversing, the left refers to the direction on the left side when the driver is sitting in the driver's seat of vehicle 2, and the right refers to the direction on the right side when the driver is sitting in the driver's seat of vehicle 2.

[0071] Regarding the travel distance of the drying component, please refer to some embodiments. Figure 2 and Figure 7 The number of air-drying components 1 is two or more, and each air-drying component 1 is arranged at intervals along the width direction of the vehicle 2. The absolute difference between the dimension L1 of the area covered by the direct airflow blown from the air outlet 11 of each air-drying component 1 at the opening 221 along the width direction and the length L2 of the opening 221 of the tailgate cavity 22 is less than 15cm. The area covered by the direct airflow blown from the air outlet 11 of each air-drying component 1 at the opening 221 refers to the collection of areas covered by the direct airflow blown from all air-drying components 1 at the opening 221, which can also be understood as the width of the air curtain formed by all air-drying components at the opening 221. This reduces the lateral movement distance of the air-drying components 1, thereby improving drying efficiency. It can be understood that in this embodiment, the area covered by the direct airflow is the area directly reached by the airflow blown from the air outlet 11 without being obstructed or changing direction. The area covered by the described direct airflow at the opening 221 is located on the plane where the opening 221 of the tailgate cavity 22 is located. The cross-sectional area of ​​the airflow blowing from the air outlet 11 gradually increases in the direction away from the air outlet. The absolute difference between the dimension L1 of the area covered by the direct airflow from the air outlet 11 of each air-drying component 1 at the opening 221 along the vehicle width direction and the length L2 of the opening 221 of the rear rim cavity 22 is less than 15cm. This includes cases where L1 is greater than L2 (e.g., L1 is 5cm, 10cm, or 15cm larger than L2) and cases where L1 is less than L2 (e.g., L1 is 5cm, 10cm, or 15cm smaller than L2). In some embodiments, L1 may also be equal to L2.

[0072] By ensuring the absolute difference between L1 and L2 is less than 15cm, the air-drying assembly 1 can dry both the entire vehicle and the tailgate cavity 22. Furthermore, during the reciprocating motion of the air-drying assembly 1, residual liquid can be accelerated to migrate along the width of the vehicle 2, thus speeding up its discharge. Further, when the reciprocating motion of the air-drying assembly 1 is within the range of 30-50cm, when the air-drying assembly 1 moves to the far right, the portion of the tailgate cavity 22 near the left end is removed from the coverage of the direct airflow from the air-drying assemblies 1. Then, when the air-drying assembly 1 moves to the left, the portion of the tailgate cavity 22 near the left end is swept away by the airflow formed by the direct airflow from the air-drying assembly 1, resulting in more thorough discharge of residual liquid and achieving a better drying effect on the tailgate cavity 22.

[0073] In some embodiments, please refer to Figure 2 and Figure 7 The direct airflow from the air outlets 11 of adjacent air-drying components 1 partially overlaps in the area covered by the opening 221. In some embodiments, the direct airflow from the air outlets 11 of adjacent air-drying components is arranged at intervals in the area covered by the opening 221.

[0074] Of course, in some other embodiments, the air outlet 11 of a single air-drying component 1 may be elongated, and the absolute difference between the size of the area covered by the direct airflow from the air outlet 11 of the single air-drying component 1 at the opening 221 along the vehicle width direction and the length of the opening 221 of the tailgate cavity 22 may be less than 15cm.

[0075] Of course, in some other embodiments, the absolute difference between the size L1 of the area covered by the direct airflow from the air outlet 11 of each air-drying component 1 along the vehicle width direction and the length L2 of the opening 221 of the tailgate cavity 22 can also be other values, such as 30cm.

[0076] In some embodiments, the motion mechanism can adjust the distance between the drying assembly 1 and the vehicle surface. By adjusting the distance between the drying assembly 1 and the vehicle surface 2, the size L1 of the area covered by the direct airflow from the air outlet 11 of each drying assembly 1 at the opening 221 along the vehicle width direction can be adjusted. The greater the distance between the drying assembly 1 and the vehicle surface 2, the larger the size L1 of the area covered by the direct airflow from the air outlet 11 of each drying assembly 1 at the opening 221 along the vehicle width direction. Alternatively, the size of L1 can also be adjusted by adjusting the power of the air supply drive assembly of the drying assembly 1; for example, increasing the power of the air supply drive assembly can increase the size of L1.

[0077] In some embodiments, in the tailgate drying method, the motion mechanism drives each drying component 1 to move synchronously. In other embodiments (not shown), in the tailgate drying method, the motion mechanism drives each drying component 1 to move asynchronously; for example, the motion mechanism can drive adjacent drying components 1 to move closer or further apart, thereby changing the position of the drying components 1 blowing onto the tailgate cavity 22 in the width direction of the vehicle 2. Of course, in some other embodiments, the number of drying components 1 can also be one.

[0078] Regarding the rear windshield drying method, please refer to some embodiments. Figures 1 to 3 The air supply drive assembly is controlled to deliver airflow to the air outlet 11, and the motion mechanism is controlled to drive the drying assembly 1 to move, so that the position of the air outlet 11 blowing towards the rear windshield 23 moves from the upper end of the rear windshield 23 to the lower end of the rear windshield 23. In some embodiments, the rear windshield drying method of this embodiment is performed after the drying operation is performed on the tailgate 21.

[0079] Specifically, in some embodiments, during the drying process of the rear windshield 23, controlling the motion mechanism to move the drying assembly 1 so that the position of the air outlet 11 blowing towards the rear windshield 23 moves from the upper end to the lower end of the rear windshield 23 includes: controlling the motion mechanism to move the drying assembly 1 from the upper end to the lower end of the rear windshield 23. Controlling the motion mechanism to move the drying assembly 1 from the upper end to the lower end of the rear windshield 23 achieves the change in the position of the air outlet 11 blowing towards the rear windshield 23. Of course, in some embodiments not shown, the motion mechanism can also control the drying assembly 1 to move backward while keeping the height of the drying assembly 1 constant, thus changing the position of the drying assembly 1 blowing towards the rear windshield 23.

[0080] Furthermore, in some embodiments, during the air-drying operation of the rear windshield 23: the airflow blown from the air outlet 11 onto the rear windshield 23 flows downward along the rear windshield 23. In this way, when residual liquid blown out from the tailgate cavity 22 splashes onto the rear windshield 23, the residual liquid on the rear windshield 23 can be blown away, improving the air-drying effect of the rear windshield 23.

[0081] Regarding the control method for the airflow direction of the air outlet 11 blowing towards the rear windshield 23, in some embodiments, after the drying operation is performed on the rear spoiler, the control motion mechanism drives the drying assembly 1 to move to change the air outlet 11's airflow direction D1, causing the air outlet 11 to blow air downwards at an angle, and causing the airflow blowing towards the rear windshield 23 of the vehicle 2 to flow downwards along the rear windshield 23, thereby performing a drying operation on the rear windshield 23. By blowing air downwards at an angle, the airflow can flow downwards along the rear windshield 23, which can suppress the upward splashing of residual liquid on the rear windshield 23.

[0082] Specifically, in some embodiments, during the drying operation of the rear windshield 23, please refer to... Figure 3 The air outlet 11 blows air downwards in a downward direction (D1), meaning the air outlet direction D1 is parallel to the vertical plane extending forward and backward. In some embodiments, the angle between the air outlet direction D1 and the rear windshield 23 of the vehicle 2 is 60°-80°. Specifically, the angle between the air outlet direction D1 and the rear windshield 23 of the vehicle 2 can be 60°, 65°, 70°, 75°, or 80°. In some embodiments, during the air drying operation of the rear windshield 23, the air outlet direction D1 of the air outlet 11 is parallel to the first plane P1.

[0083] Of course, in some other embodiments, the angle between the downward airflow direction D1 of the air outlet 11 of the air-drying assembly 1 and the rear windshield 23 of the vehicle 2 can also be less than 60°. For example, the angle between the airflow direction D1 and the rear windshield 23 can be 30°, 45°, 50°, or 55°. It should be noted that the angle between the airflow direction D1 of the air outlet 11 of the air-drying assembly 1 described in this application and the rear windshield 23 is based on the premise that the airflow can flow downward along the rear windshield 23. Of course, in some embodiments, the air-drying assembly 1 moves horizontally from front to back when blowing on the rear windshield 23.

[0084] In some embodiments, please refer to Figure 2 The number of air-drying components 1 is two or more, and each air-drying component 1 is arranged at intervals along the width direction of the vehicle 2. The length L1 (i.e., the dimension along the width direction) of the area covered by the direct airflow blown from the air outlet 11 of each air-drying component 1 at the rear windshield is greater than or equal to the width of the rear windshield 23. In this embodiment, the area covered by the direct airflow is the area directly reached by the airflow blown from the air outlet 11 without being obstructed or changing direction. The area covered by the direct airflow blown from the air outlet 11 of each air-drying component 1 at the rear windshield refers to the collection of the areas covered by the direct airflow blown from all air-drying components 1 on the surface of the vehicle 2, which can also be understood as the width of the air curtain formed by all air-drying components at the rear windshield 23. In some embodiments, the areas covered by the direct airflow blown from the air outlet 11 of adjacent air-drying components on the surface of the vehicle 2 partially overlap. In some embodiments, the areas covered by the direct airflow blown from the air outlet 11 of adjacent air-drying components on the surface of the vehicle 2 are arranged at intervals.

[0085] In some other embodiments, the length of the area covered by the direct airflow from the air outlet 11 of a single air-drying component 1 along the width direction of the vehicle 2 (i.e., the dimension along the width direction of the vehicle) on the surface of the vehicle 2 may be greater than or equal to the dimension of the rear windshield 23 along the width direction of the vehicle 2. In this embodiment, the number of air-drying components 1 may be one or more.

[0086] Some embodiments of this application also provide an automatic car wash drying method applied to automatic car wash equipment. Please refer to [link / reference]. Figures 1 to 3 The automatic car wash drying method applied to automatic car wash equipment includes: controlling the motion mechanism to drive the drying component 1 to move from the front of the vehicle 2 to the rear of the vehicle 2, performing a drying operation on the vehicle 2. During the process of the drying component 1 moving from the front of the vehicle 2 to the rear of the vehicle 2, the rear of the vehicle 2 is dried using the vehicle rear drying method applied to the automatic car wash equipment as described in any of the above embodiments, and the specific details will not be elaborated further.

[0087] In some embodiments, please refer to Figures 1 to 3 The automatic car wash drying method further includes a first drying stage and a second drying stage. In the first drying stage, a control motion mechanism moves the drying component 1 from the rear of the vehicle 2 to the front of the vehicle 2 to perform a first drying operation on the vehicle 2. In the second drying stage, the control motion mechanism moves the drying component 1 from the front of the vehicle 2 to the rear of the vehicle 2 to perform a second drying operation on the vehicle 2. The rear drying method of the automatic car wash equipment described in any of the above embodiments is performed in the second drying stage. Alternatively, in some embodiments, in the first drying stage, the control motion mechanism moves the drying component 1 from the front of the vehicle 2 to the rear of the vehicle 2 to perform a first drying operation on the vehicle 2. In the second drying stage, the control motion mechanism moves the drying component 1 from the rear of the vehicle 2 to the front of the vehicle 2 to perform a second drying operation on the vehicle 2. The rear drying method of the automatic car wash equipment described in any of the above embodiments is performed in the first drying stage.

[0088] Some embodiments of this application also provide an automatic car wash device; please refer to [reference needed]. Figures 1 to 3The automatic car wash equipment includes a car wash device, a drying assembly 1, a motion mechanism, an air supply drive assembly, and a control assembly. The car wash device is used to wash a vehicle 2. The drying assembly 1 has an air outlet 11 for blowing air onto the vehicle 2 being washed. The drying assembly 1 is disposed on the motion mechanism, which is used to drive the drying assembly 1 to move. The air supply drive assembly is used to deliver airflow to the air outlet 11 of the drying assembly 1. Both the motion mechanism and the air supply drive assembly are connected to the control assembly, which is used to control the motion mechanism to drive the drying assembly 1 to move relative to the vehicle 2, and to control the air supply drive assembly to deliver air to the air outlet 11 to perform the drying operation. The automatic car wash equipment is also used to perform a vehicle rear end drying method, a vehicle rear drying method, or an automatic car wash drying method as described in any of the above embodiments.
