Description

Technical Field

[0001] The present invention relates to the technical field of car wash machines, and specifically to a conveying and guiding device, method, and system for an unattended car wash machine. Background Art

[0002] An unattended car wash machine is a car wash device integrating intelligence and automation. It can provide efficient and convenient car wash services for vehicles without manual operation. Currently, the unattended tunnel car wash devices on the market generally use a double-sided chain plate track system to automatically complete the car washing work. In this system, the car must be in the P gear state to ensure the normal operation of the chain plate conveying mechanism. In contrast, the traditional tunnel attended car wash method requires the car to be in the N gear state. Due to the difference in operation modes, there are significant differences in the user experience between unattended and attended car washes. Currently, due to the different design of the conveying track of the double-sided chain plate track device from the attended device, its investment cost has increased significantly, about N times the cost of the original conveying track (the value of N ranges from 3 to 6). In addition, the civil construction process is more complex, and the cost is about M times the original (the value of M ranges from 2 to 4). More importantly, the existing attended devices cannot be directly transformed into unattended devices through simple optimization and improvement to meet the operation requirements. In view of this, there is an urgent need for a new type of conveying and guiding device, method, and system for unattended car wash machines.

[0003] After retrieval, the Chinese invention patent with the publication number "CN109131236A" discloses "An unattended car wash guiding device and system". This application is provided with display devices on both sides of the car wash machine that output driving prompt information to users, so that users can clearly understand the driving instructions of the vehicle through the display devices during the process of driving the vehicle into the designated car wash position, and can quickly adjust according to the driving instruction information.

[0004] In addition, the Chinese invention patent with the publication number "CN115179901A" discloses "An unattended full-automatic car wash guiding device". This application adopts parallel and opposite input and output. When entering the range of the car wash machine, the car is adjusted towards the middle by the left and right inclined roller belts, so that the car is centered when entering the conveyor belt. The conveyor belt is provided with detection units at the entrance interface of each process of the car wash machine, which can start the corresponding control switches. The control switches control the conveyor belt to perform commands such as staying and decelerating, and cooperate with each process mechanism in the car wash machine to achieve efficient cleaning, making the cleaning effect of the car wash machine better during the fixed-duration cleaning process than the traditional uniform traction cleaning effect.

[0005] However, the devices disclosed in the existing public technologies still have several technical limitations in the actual application process, which are mainly manifested as follows: The device does not set a dynamic correction system for the traveling trajectory of the vehicle wheel body. When facing vehicles with different wheelbases and tire widths, its guiding accuracy significantly decreases. When there is a deviation between the vehicle wheelbase parameter and the preset track parameter, the wheel body and the guiding component are prone to asymmetric contact phenomena, which to a certain extent causes the problem that the vehicle posture will shift during the cleaning process of the car wash. In addition, the above-mentioned disclosed device and the supporting system method need to lay extended tracks and configure multiple groups of guiding components during the infrastructure implementation stage, resulting in a significant increase in construction costs and a large space occupancy rate, which seriously restricts the modular deployment and multi-scenario application expansion of the unattended car wash. Summary of the Invention

[0006] The purpose of the present invention is to provide a conveying and guiding device, method and system for an unattended car wash to solve the problems proposed in the above background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solutions: In the first aspect, a conveying and guiding device for an unattended car wash is proposed, which is installed in a groove opened on the bottom surface of the unattended car wash body and includes: A transverse track member, horizontally and fixedly installed in the groove at the entrance end of the unattended car wash body; A limiting track member, mechanically connected to the transverse track member through a sliding assembly method and arranged in an adjustment groove communicated with the entrance groove. The spatial positioning of the limiting track member is adjusted through the transverse track member according to the distance between the profiles on both sides of the vehicle; A transportation track member, laid and installed in an assembly groove on the side of the unattended car wash body away from the adjustment groove; The working surfaces in contact with the vehicle wheel body inside the limiting track member and the transportation track member are both configured with protective components. The protective components drive the chain through a sprocket transmission mechanism to achieve synchronous displacement. The protective components correct the traveling direction during the transmission according to the tire width of the vehicle wheel body; The protective component includes: A sleeve, with both ends respectively connected to the surfaces of the chains on both sides of the sprocket transmission mechanism. A main induction pedal is fixedly installed in the middle of the outer surface of the sleeve for contacting the tire tread. Two protective pedals that can slide axially along the sleeve are symmetrically arranged outside the sleeve. The protective pedals are controlled by a driving device inside the sleeve. Secondary induction pedals are respectively integrated at the outer edges of the two protective pedals and are used to contact the sidewall curved surface of the tire. When the main induction pedal contacts the tire tread, the driving device is triggered to control the driving, and the driving device controls to terminate after the secondary induction pedals are in full contact with the tire sidewall.

[0008] As a further preference of this technical solution, on both sides of the connection area between the transportation track member and the transverse track member, there are several guiding guardrails designed based on the width of the transportation track member for guiding the vehicle to transition from the transverse track member to the transportation track member.

[0009] As a further preference of this technical solution, a screw cover is installed at the barrel mouth end of the sleeve through threaded fit. Among them, at the central axial position of the inner cavity of the screw cover and the central axial position of the bottom end of the outer barrel of the sleeve, there are telescopic screw rods that are threadedly matched with them. The axial ends of each telescopic screw rod are respectively connected to the surface of the nodes of the double-sided chains of the sprocket transmission mechanism; Assembly notches are symmetrically opened on both sides of the sleeve surface. The driving device is a micro bidirectional electric push rod using an integrated power supply module. Driving rods are respectively fixed on the surfaces at both ends of the micro bidirectional electric push rod. One end of the driving rod passes through the assembly notch and is fixedly connected to the protective pedal.

[0010] As a further preference of this technical solution, the transverse track member includes: A collaborative track, fixedly installed inside the groove at the entrance end, with its surface flush with the horizontal plane of the unattended car wash machine body; An electric damping telescopic machine, installed at the end of the collaborative track adjacent to the transportation track member. The telescopic shaft body of the electric damping telescopic machine is accommodated inside the internal cavity of the collaborative track and is fixed to the transmission frame; Connection notches designed according to the width adjustment groove parameters are provided on both sides of the end of the collaborative track away from the electric damping telescopic machine. The transmission frame forms a sliding assembly with the collaborative track through the connection notches, and one end of the collaborative track passes through the connection notch and forms a mechanical connection with one end of the surface of the limit track member.

[0011] As a further preference of this technical solution, a constraint component is installed at a position outside the collaborative track adjacent to the electric damping telescopic machine for correcting the moving direction of the vehicle; The constraint component includes: Two transmission joints, evenly fixed at both ends of the outside of the collaborative track away from the transportation track member; a carrying frame, fixed on the other side of the outside of the collaborative track. A threaded lead screw structure is installed inside the carrying frame. The thread of the screw inside the threaded lead screw structure consists of two opposite threads. A partition board fixed inside the carrying frame is sleeved at the intersection of the two threads outside the screw. Connection seats that are slidably connected inside the carrying frame are respectively screwed at both axial ends of the screw; A transmission arm is hingedly installed between the connection seat and the transmission joint at the same axial position. An activity notch for allowing the transmission arm to move is opened at the contact position between the transmission arm and the transmission joint; During the operation of the threaded lead screw structure, the screw rod changes the relative position between the two transmission arms by adjusting the position of the connecting seat. Based on the change in the relative position, the two transmission arms form a guiding clamping opening, and the tire is guided to turn based on the guiding clamping opening, thereby correcting the moving direction of the vehicle.

[0012] As a further preference of this technical solution, the limit rail member includes: On both sides of the bottom end of the load-bearing frame, rollers that can move along the width side of the adjustment groove are symmetrically arranged. In the middle of the interior of the load-bearing frame, a contact plate for tire bearing is integrally installed. On the bottom of both inner walls of the load-bearing frame, sprocket grooves for installing the sprocket transmission mechanism are provided. On the top of the load-bearing frame, unit installation grooves are symmetrically opened. A damping rod is fixed in the unit installation groove, and a reset-function electronic rotating joint is fixedly connected to the surface of the damping rod. An end limit baffle that contacts the tire surface is fixedly connected inside the electronic rotating joint.

[0013] As a further preference of this technical solution, the transport rail member includes: Two assembly plates are arranged in parallel on both sides of the inner wall of the assembly groove. A bearing plate for tire contact is fixedly connected across the top ends of the assembly plates. Several reinforcing seats for support are provided on the side of the assembly plate close to the inner wall of the assembly groove. An equal number of stabilizing seats are correspondingly arranged at the bottom of the assembly plate. The top surface of the stabilizing seat contacts the bottom surface of the bearing plate and is used to disperse the stress exerted by the tire on the surface of the bearing plate; The sprocket transmission mechanism arranged inside the transport rail member is assembled and installed on the outer surface of the two groups of assembly plates and does not interfere with the reinforcing seats.

[0014] As a further preference of this technical solution, a height limit frame is arranged outside the entrance area of the unattended car wash machine body. Visual monitoring components and a power supply control terminal are symmetrically arranged on both sides at the entrance of the unattended car wash machine body. The power supply control terminal and the visual monitoring component are orthogonally distributed along the axial direction of the height limit frame; The multi-functional power supply control terminal is used to provide continuous energy supply for the transverse rail member, the limit rail member, and the transport rail member, and the visual monitoring component is used to collect vehicle parameters in real time.

[0015] In the second aspect, to improve the above technical solution, the present invention also proposes an implementation method for the conveying and guiding device of an unattended car wash machine, based on the above-disclosed conveying and guiding device of an unattended car wash machine, and includes: According to the vehicle parameters of the vehicle to be washed obtained in real time by the visual monitoring component, the vehicle parameters include the tire tread width, the curvature radius of the tire side surface, the vehicle wheelbase length, and the distance between the two side contours of the vehicle; According to the obtained distance parameter between the two side contours of the vehicle, adjust the distance of the limit rail member to match the distance between the two side contours of the vehicle; According to the obtained tire tread width parameter, drive the micro bidirectional electric push rod inside the protection component, and control the synchronous displacement of the two protection pedals along the axial direction of the sleeve until the secondary induction pedal contacts the tire side surface; Based on the tire side surface curvature radius data, the electronic rotating joint dynamically adjusts the inclination angle of the limit baffle inside the limit track component to ensure that the tire travel trajectory remains dynamically coincident with the central axis of the limit track component; When the vehicle wheel body enters the connection area between the transverse track component and the transport track component, start the threaded lead screw structure of the restraint component, and drive the two connecting seats to move towards each other through the bidirectional thread of the screw rod, prompting the transmission arm to generate an angular deflection based on the movable notch, forming a guiding clamping port matching the travel direction of the vehicle wheel body; During the movement of the vehicle along the transport track component, the sprocket transmission mechanism drives the protection component to displace synchronously with the chain, the primary induction pedal fits the tire tread, and triggers the operation of the electric damping telescopic machine, so that the secondary induction pedal fits on the tire side, limiting the steering angle of the vehicle placed inside the unattended car wash machine.

[0016] In a third aspect, to further improve the above technical solution, the present invention also proposes a conveying and guiding system for an unattended car wash machine, which uses the implementation method of a conveying and guiding device for an unattended car wash machine disclosed above.

[0017] Compared with the prior art, the beneficial effects of the present invention are: For the conveying and guiding device, method and system of the unattended car wash machine, through the protection component installed in the limit track component and the transport track component, after the tire of the vehicle contacts the primary induction pedal inside the protection component, it triggers the start of the electric damping telescopic machine, and makes the two secondary induction pedals move towards each other to limit the tire, so that when the vehicle is washed in the unattended car wash machine, it can maintain a stable travel trajectory, effectively avoiding the problem of poor car wash effect caused by tire shaking or deviation; In addition, by using the visual monitoring component to collect vehicle parameters in real time, drive the electric damping telescopic mechanism built in the transverse track component to adjust the displacement of the transmission frame, so that the load-bearing frame realizes synchronous displacement matching the distance from the tire along the adjustment groove, and make the restraint component adopt a bidirectional threaded lead screw transmission structure to drive the two connecting seats to generate opposite displacements, and through the movement of the transmission arm at the movable notch, form a guiding clamping port corresponding precisely to the travel direction of the wheel body, completing the real-time offset correction of the vehicle movement axis; It should also be added that by using an embedded groove assembly design for the horizontal track member, the limit track member and the transport track member and installing them at the entrance of the unattended washing machine, not only simplifies the installation steps, but also ensures that each track member can still maintain a tight connection during long-term use, effectively improving the overall stability and durability of the car wash machine. At the same time, it also provides great convenience for possible future equipment upgrades or repairs, reducing the time and cost consumption caused by equipment disassembly and reinstallation, making the operation of the unattended car wash machine more efficient and reliable.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] Before discussing the innovative technical solutions proposed in this application, it must be clear that the technical solutions proposed in this application utilize the principle of cross-conveying of the left and right wheels of an automobile to convey a vehicle in the N-gear state. Refer to Figure 1 It can be seen that the device disclosed in this application is installed in a groove opened on the bottom surface of the unattended car wash machine body 5 and includes: The transverse rail member 1 is horizontally and fixedly installed in the groove at the entrance end of the unattended car wash machine body 5.

The surface of the cooperative rail 101 is flush with the horizontal plane of the unattended car wash machine body 5 and is used for the synchronous movement of the vehicle wheels. The design that the surface of the cooperative rail 101 is flush with the horizontal plane of the unattended car wash machine body 5 ensures the stability and smoothness of the wheels during the conveying process, and avoids the vehicle offset or jamming phenomenon caused by the contact between the wheels and the rail.

[0023] The electric damping telescopic machine 110 is installed at the end of the cooperative rail 101 adjacent to the transport rail member 4. The telescopic shaft body of the electric damping telescopic machine 110 is accommodated in the internal cavity of the cooperative rail 101 and is fixed to the transmission frame 102.

[0024] On both sides of the end of the cooperative rail 101 far from the electric damping telescopic machine 110, there are connection notches 103 designed according to the parameter of adjusting the groove width. The transmission frame 102 forms a sliding assembly with the cooperative rail 101 through the connection notches 103. One end of the cooperative rail 101 passes through the connection notches 103 and one end of the surface of the limit rail member 2 to form a mechanical connection. It should be noted that in this application, the mechanical connection is a fixed connection.

[0025] It should be added that in this embodiment, a constraint component is installed at a position outside the cooperative rail 101 adjacent to the electric damping telescopic machine 110 for correcting the moving direction of the vehicle.

[0026] Specifically, the constraint component includes: Two drive joints are evenly fixed at both ends of the outer side of the cooperation track 101 away from one side of the transportation track member 4; a carrying frame 108 is fixed on the other side of the outer side of the cooperation track 101. A threaded lead screw structure 104 is installed in the carrying frame 108. The thread of the screw 105 in the threaded lead screw structure 104 is composed of two sections of opposite threads. A partition plate 106 fixed in the carrying frame 108 is sleeved at the intersection of the two sections of threads outside the screw 105. Connecting seats 107 that are slidably connected in the carrying frame 108 are respectively screwed at both axial ends of the screw 105.

[0027] It should be noted that, referring to Figure 3 it can be seen that in this embodiment, the threaded lead screw structure 104 is a common transmission structure in the prior art field. Specifically in this application, it includes a motor installed at one end outside the carrying frame 108, and the shaft body of the motor penetrates the carrying frame 108 and is fixed to one end of the screw 105.

It should be noted that with the operation of the threaded lead screw structure 104, the screw 105 changes the relative position between the two transmission arms 111 by adjusting the position of the connecting seat 107.

The protective pedals 904 are controlled by a driving device inside the sleeve 901. Secondary induction pedals 908 are respectively integrated at the outer edges of the two protective pedals 904 and are used for contacting the sidewall curved surface. When the main induction pedal 906 contacts the tread surface, it triggers the driving device to control the drive, and the driving device controls to terminate after the secondary induction pedals 908 are in full contact with the sidewall.

[0044] As a preferred implementation manner, it should be supplemented that this implementation manner also proposes an implementation method for the conveying and guiding device of the unattended car wash machine. It should be clear that an implementation method for the conveying and guiding device of the unattended car wash machine is based on a conveying and guiding device of the unattended car wash machine and includes: step S100 - step S600.

[0045] Step S100: Obtain the vehicle parameters of the vehicle to be washed in real time according to the visual monitoring component 6. The vehicle parameters include the tire tread width, the curvature radius of the tire side surface, the vehicle wheelbase length, and the distance between the two side contours of the vehicle.

[0046] It should be clear that in this implementation manner, the visual monitoring component 6 includes: two types of high - definition cameras, which are installed at different positions on one side of the height limit frame 7. The two types of high - definition cameras are electrically connected to the power supply control terminal 8. The high - definition cameras are used to capture the image information when the vehicle travels to the entrance area of the unattended car wash machine body 5, retrieve the vehicle parameters of the same vehicle type in the network based on the image information, and obtain the parameter data of the tire surface, that is, the tire tread width and the curvature radius of the tire side surface marked on the outer surface of the tire, based on the image information.

[0047] Step S200: Adjust the distance between the limit track members 2 to match the distance between the two side contours of the vehicle according to the obtained distance parameter between the two side contours of the vehicle.

[0048] Specifically, when step S200 is actually running, first, the driving motor 208 drives the linkage rod to rotate, the linkage rod drives the two transmission sprockets 207 to rotate synchronously, the transmission sprockets 207 drive the transmission chain 211 to move, and further drive the load-bearing frame 201 to move along the width direction of the adjustment groove until the distance between the limiting track members 2 matches the distance between the profiles on both sides of the vehicle.

[0049] Step S300: According to the obtained width parameter of the wheel tread, drive the micro bidirectional electric push rod 905 inside the protection component 9, and control the two protection pedals 904 to synchronously displace along the axial direction of the sleeve 901 until the secondary induction pedal 908 contacts the sidewall curved surface.

[0050] Specifically, when step S300 is actually running, first, after the primary induction pedal 906 contacts the tire tread, an electric signal is triggered. The electric signal is transmitted to the integrated power supply module of the micro bidirectional electric push rod 905. After receiving the electric signal, the integrated power supply module controls the micro bidirectional electric push rod 905 to start. The micro bidirectional electric push rod 905 pushes the protection pedal 904 to move along the axial direction of the sleeve 901 through the drive rods 903 at both ends until the secondary induction pedal 908 contacts the curved surface of the tire sidewall. At this time, the micro bidirectional electric push rod 905 stops running, completing the displacement adjustment of the protection pedal 904. Through such a design, the protection component 9 can be adaptively adjusted according to the width of the tire, ensuring the stability and safety of the tire during transmission.

[0051] Step S400: The electronic rotating joint 202 dynamically adjusts the inclination angle of the limiting baffle 203 inside the limiting track member 2 based on the data of the curvature radius of the sidewall curved surface, so as to ensure that the traveling track of the tire coincides dynamically with the central axis of the limiting track member 2.

[0052] Specifically, when step S400 is actually running, the electronic rotating joint 202 receives the curvature radius data and adjusts the inclination angle of the limiting baffle 203. When the vehicle tire travels onto the limiting track member 2, the tire curved surface contacts the limiting baffle 203, and the limiting baffle 203 is stressed and rotates around the damping rod 210, while driving the electronic rotating joint 202. The electronic rotating joint 202 dynamically adjusts the inclination angle of the limiting baffle 203 according to the preset curvature radius data, ensuring that the traveling track of the tire coincides dynamically with the central axis of the limiting track member 2. Such a design can further improve the stability and safety of the vehicle during transmission.

[0053] Step S500: When the vehicle wheel enters the connection area between the lateral rail member 1 and the transport rail member 4, start the threaded lead screw structure 104 of the restraint member. Drive the two connecting seats 107 to move towards each other through the bidirectional thread of the lead screw 105, so that the transmission arm 111 generates an angular deflection based on the movable notch 109, forming a guiding clamping port matching the traveling direction of the vehicle wheel.

[0054] Specifically, during the actual operation of step S500, the motor starts, and the shaft body of the motor drives the lead screw 105 to rotate. Since the thread of the lead screw 105 consists of two opposite threads, during the rotation of the lead screw 105, the connecting seats 107 on the two threads will move towards the two ends of the lead screw 105 respectively. However, due to the existence of the baffle 106, the two connecting seats 107 actually move towards each other within the mounting frame 108. As the connecting seats 107 move, the transmission arm 111 hinged to the connecting seats 107 will also generate an angular deflection. Since there is a movable notch 109 hinged between the transmission arm 111 and the transmission joint, the transmission arm 111 can move based on the movable notch 109, thereby forming a guiding clamping port. The shape and size of this guiding clamping port will be dynamically adjusted according to the traveling direction and position of the vehicle wheel, so as to ensure that the vehicle wheel can be accurately guided onto the transport rail member 4 and maintain the correct traveling direction.

[0055] Step S600: During the movement of the vehicle along the transport rail member 4, the sprocket transmission mechanism drives the protection member 9 to displace synchronously with the chain. The primary induction pedal 906 fits against the tread surface and triggers the operation of the electric damping telescopic machine 110, so that the secondary induction pedal 908 fits against the side of the tire, restricting the steering angle of the vehicle placed within the unattended car wash body 5.

[0056] As a preferred implementation manner, a conveying and guiding system for an unattended car wash is also proposed. It should be noted that a conveying and guiding system for an unattended car wash uses an implementation method of an unattended car wash conveying and guiding device.
