Description

Technical Field

[0001] This utility model belongs to the field of automotive maintenance technology, and in particular relates to a vehicle chassis exterior spraying device. Background Technology

[0002] Rust-preventive paint is mainly divided into two categories: physical and chemical rust-preventive paint. The former relies on the proper combination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances. Rust-preventive paint is widely used, especially in automobile maintenance, where it is frequently applied. For example, the chassis of a car is an area that needs to be sprayed with rust-preventive paint to prevent corrosion.

[0003] A search revealed Chinese patent application number 201920905331.8, which discloses an automotive chassis rust-preventive paint spraying device. The device includes a connecting block, a first support rod fixedly connected to one side of the connecting block, and a second support rod fixedly connected to one side of the first support rod. A sliding block is fitted onto the outer surface of the second support rod, and the second support rod is slidably connected to the paint spray nozzle via the sliding block on its outer surface. This automotive chassis rust-preventive paint spraying device, when placed under the car, allows the spray nozzle to sweep and spray the chassis by pushing an L-shaped push rod. Workers do not need to tilt their heads back or hold the paint gun, reducing labor intensity and achieving ease of use. The support base increases the contact area between the device and the ground, improving stability. Multiple support legs can be connected to raise the device's height, enabling spraying of cars with higher chassis, thus improving practicality. However, it has the following drawbacks: manual adjustment of the paint spray nozzle position by pushing the push rod is required, which is laborious and time-consuming. Furthermore, manual pushing of the paint spray nozzle can lead to uneven spraying due to inconsistent speed. Utility Model Content

[0004] This utility model provides a car chassis exterior painting device, which aims to solve the problem that the existing technology requires manual pushing of the push rod to adjust the position of the paint spray pipe. Manual operation is time-consuming and laborious, and the paint spray pipe cannot move at a uniform speed when manually pushed, which easily leads to uneven painting.

[0005] This utility model is implemented as follows: a car chassis exterior painting device includes a main frame and a running board. The inner wall of the main frame is provided with electric slide rails, which are symmetrically distributed along the vertical center line of the main frame. The outer walls of the two moving ends of the electric slide rails are fixedly connected to an equipment plate, and the inner wall of the equipment plate is fixedly connected to a metal tube. The lower surface of the metal tube is connected to an electrically controlled spray head, which is evenly distributed on the outer wall of the metal tube. The outer wall of the metal tube is connected to a liquid pipe. The outer wall of the equipment plate is respectively provided with an equipment tube, a controller, and a signal transceiver. A distance sensor is provided inside the equipment tube. The signal transceiver, the electric slide rails, the electrically controlled spray head, the distance sensor, and the controller are electrically connected.

[0006] Preferably, an inclined guide plate is fixedly connected to the outer wall of the travel plate.

[0007] Preferably, the upper surfaces of the inclined guide plate and the travel plate are provided with anti-slip textures.

[0008] Preferably, a rubber pad is fixedly connected to the lower surface of the travel plate and the inclined guide plate.

[0009] Preferably, the upper inner wall of the device tube is provided with glass.

[0010] Preferably, the inner wall of the main frame is provided with a cleaning plate, and a sponge pad matching the equipment pipe is fixedly connected to the lower surface of the cleaning plate.

[0011] Preferably, the outer wall of the cleaning plate is provided with a slot, and the inner wall of the main frame is fixedly connected with a plug that matches the slot.

[0012] Preferably, the lower end of the equipment tube is provided with an external thread, and the lower surface of the equipment plate is provided with an internal thread hole that matches the external thread.

[0013] Compared with the prior art, the embodiments of this application have the following main advantages:

[0014] By matching signals between a mobile terminal and a signal transceiver, personnel can operate the mobile terminal to control the start and stop of the electric slide rail, electronically controlled nozzles, and distance sensors via the signal transceiver and controller. When painting the car chassis, the vehicle moves onto the drive platform, with the equipment platform located below the chassis. Due to the irregular shape of the car chassis caused by the tires, the controller controls the movement of the electric slide rail, allowing the metal tube and electronically controlled nozzles to move at a uniform speed under the car chassis, thus ensuring the uniformity of the electronically controlled nozzles' spraying. The other end of the liquid tube is connected to a liquid pump, which is controlled by the controller. Through the operation of the liquid pump, the electronically controlled nozzles can spray the car chassis. Multiple distance sensors in front of the electronically controlled nozzles detect the car chassis. By detecting the distance to the car chassis, the distance sensors send signals to the controller. The controller receives the signals from the distance sensors and controls the opening and closing of different electronically controlled nozzles, ensuring that the electronically controlled nozzles spray the car chassis, reducing the waste of spraying liquid, eliminating the need for manual operation, achieving a high degree of automation, saving time and labor, and improving the efficiency of car chassis painting.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides an automotive chassis exterior coating device, such as... Figure 1-5 As shown, the device includes a main frame 1 and a travel plate 2. The inner wall of the main frame 1 is provided with electric slide rails 4, which are symmetrically distributed along the vertical center line of the main frame 1. The outer walls of the moving ends of the two electric slide rails 4 are fixedly connected to equipment plates 5, and the inner walls of the equipment plates 5 are fixedly connected to metal pipes 6. The lower surface of the metal pipes 6 is connected to electrically controlled nozzles 7, which are evenly distributed on the outer walls of the metal pipes 6. The outer walls of the metal pipes 6 are connected to liquid pipes 8. The outer walls of the equipment plates 5 are respectively provided with equipment pipes 9, controllers 11, and signal transceivers 12. The inside of the equipment pipes 9 is provided with distance sensors. The signal transceivers 12, electric slide rails 4, electrically controlled nozzles 7, and distance sensors are electrically connected to the controller 11.

[0024] It should be noted that, in existing technologies, the position of the paint spray nozzle needs to be adjusted manually by pushing a push rod. This manual operation is time-consuming and laborious, and the paint spray nozzle cannot move at a uniform speed when manually pushed, easily leading to uneven paint application. Therefore, to solve the problems of manual adjustment of the paint spray nozzle position in existing technologies, which are time-consuming and laborious, and the paint spray nozzle cannot move at a uniform speed, easily leading to uneven paint application, this solution allows personnel to perform signal matching between a mobile terminal and a signal transceiver 12. Personnel can operate the mobile terminal to control the start and stop of the electric slide rail 4, the electric spray head 7, and the distance sensor through the signal transceiver 12 and the controller 11. When it is necessary to paint the car chassis, the vehicle drives onto the driving platform 2, and the equipment platform 5 is located below the chassis. Due to the irregular shape of the car chassis caused by the car tires, The controller 11 controls the movement of the moving end of the electric slide rail 4, enabling the metal tube 6 and the electronically controlled nozzle 7 to move at a uniform speed under the car chassis, thus ensuring the uniformity of the spraying by the electronically controlled nozzle 7. The other end of the liquid tube 8 is connected to a liquid pump, which is controlled by the controller 11. Through the operation of the liquid pump, the electronically controlled nozzle 7 can spray the car chassis. Multiple distance sensors in front of the electronically controlled nozzle 7 detect the car chassis. By detecting the distance to the car chassis through the distance sensors, the distance sensors send signals to the controller 11. The controller 11 receives the signals from the distance sensors and controls different electronically controlled nozzles 7 to open and close, ensuring that the electronically controlled nozzle 7 sprays the car chassis, reducing the waste of spraying liquid, eliminating the need for manual operation, achieving a high degree of automation, saving time and labor, and improving the efficiency of car chassis spraying.

[0025] In a further preferred embodiment of this utility model, such as Figure 1 As shown, an inclined guide plate 3 is fixedly connected to the outer wall of the driving plate 2.

[0026] In this embodiment, the inclined guide plate 3 facilitates the vehicle's movement onto the driving platform 2.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the upper surfaces of the inclined guide plate 3 and the travel plate 2 are provided with anti-slip textures.

[0028] In this embodiment, the anti-slip texture increases the friction between the driving plate 2 and the inclined guide plate 3, preventing the vehicle from slipping on the driving plate 2 and the inclined guide plate 3.

[0029] In a further preferred embodiment of this utility model, such as Figure 5 As shown, rubber pads 17 are fixedly connected to the lower surfaces of the travel plate 2 and the inclined guide plate 3.

[0030] In this embodiment, the noise generated by the collision between the equipment and the ground is reduced by the rubber pad 17.

[0031] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the upper inner wall of the equipment tube 9 is provided with glass 10.

[0032] In this embodiment, the distance sensor is protected by glass 10, which improves the service life of the distance sensor.

[0033] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a cleaning plate 13 is provided on the inner wall of the main frame 1, and a sponge pad 14 matching the equipment pipe 9 is fixedly connected to the lower surface of the cleaning plate 13.

[0034] In this embodiment, when the electronically controlled nozzle 7 sprays, some spray will fall on the glass 10. After long-term operation, the spray liquid will cover the glass 10, thereby affecting the operation of the distance sensor. When the equipment stops working, the moving recovery device tube 9 of the moving end of the electric slide rail 4 moves to the bottom of the sponge pad 14 and wipes the upper surface of the glass 10 through the sponge pad 14 to ensure that the upper surface of the glass 10 is clean.

[0035] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the outer wall of the cleaning plate 13 is provided with a slot 15, and the inner wall of the main frame 1 is fixedly connected with a plug 16 that matches the slot 15.

[0036] In this embodiment, the sponge pad 14 needs to be replaced regularly. The cleaning plate 13 and the insert block 16 are connected by an insert, which facilitates the replacement of the cleaning plate 13.

[0037] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the lower end of the outer wall of the equipment tube 9 is provided with an external thread, and the lower surface of the equipment plate 5 is provided with an internal thread hole that matches the external thread.

[0038] In this embodiment, the threaded connection between the equipment tube 9 and the equipment plate 5 facilitates the disassembly and assembly of the equipment tube 9, and makes it easier for personnel to inspect and maintain the equipment tube 9.
