[0002] The washing system is a key auxiliary system for ensuring the driving safety of commercial vehicles. Its core function is to clean the windshield to ensure clear driver visibility. The wash tank stores the washing solution, which is then delivered to the wash nozzles via a water pipe and sprayed out by an electric pump. Currently, the wash tank in commercial vehicles is typically located inside the dashboard. However, the dashboard side panels are mostly vertical, requiring a safe distance between them and the wash tank inlet, creating an inherent angle. This structure leads to washing solution leakage during filling due to the inlet's improper placement, which can corrode internal electrical components in the dashboard and affect their normal operation and stability. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a convenient filling device for a washing jug and a commercial vehicle.

[0004] To achieve the above objectives, this utility model employs a convenient filling washing jug device, comprising an upper washing jug body, a lower washing jug body, a telescopic tube, and a lid; the upper washing jug body is integrally formed with a spout, and the telescopic tube is retractably fitted inside the spout, with a limiting structure at the extreme extension end of the telescopic tube to prevent it from completely detaching from the spout; the lower washing jug body has a protruding platform, which is connected to the washing motor via a sealing sleeve; the lower washing jug body and the upper washing jug body are connected to form a closed washing jug body, which has multiple mounting points, one of which is fitted with a spring nut, and the remaining mounting points are fixed to the instrument panel beam bracket with M6 bolts; the washing jug body is integrally injection molded with a wire harness fixing bracket for fixing the water pipe and the washing motor wire harness; the lid is a press-type sealing structure, and the lid is connected to the spout via a collar.

[0005] As an improvement, the maximum extension length of the telescopic tube is 9cm, and the telescopic tube forms an axially extending washing liquid filling guide channel when it is pulled out.

[0006] As an improvement, a limiting protrusion is integrally formed on the outer circumference of the outer end of the spout, the inner diameter of the collar is smaller than the outer diameter of the limiting protrusion, and the limiting protrusion fits into the inner end face of the lid to form an axial sealing structure.

[0007] As an improvement, the upper body and lower body of the washing pot are fixed together by welding with a hot plate.

[0008] As an improvement, the output nozzle of the washing motor is sealed to one end of the water pipe, and the other end of the water pipe is fitted with a protective sleeve and passes through the front sheet metal; the protective sleeve is fitted at the contact point between the water pipe and the front sheet metal.

[0009] As an improvement, the mounting points on the washing jug body that are fixed to the instrument panel tube beam bracket by M6 bolts are all designed with oval holes, and the length direction of the oval holes is consistent with the extension direction of the instrument panel tube beam.

[0010] As an improvement, the inner wall of the sealing sleeve is provided with at least one annular sealing rib, which is interference-fitted with the mounting end face of the washing motor.

[0011] As an improvement, the telescopic tube has a horizontal guide opening at its inlet, and the inner wall of the horizontal guide opening is a smooth arc surface.

[0012] In a second aspect, this utility model also provides a commercial vehicle, wherein the instrument panel of the commercial vehicle is equipped with the aforementioned convenient refilling wash bottle device, and the convenient refilling wash bottle device is fixedly connected to the instrument panel tube beam bracket of the commercial vehicle through the mounting point of its wash bottle body.

[0013] Compared with the prior art, the convenient filling washing pot device of this utility model has the following beneficial effects: 1. Convenient and efficient filling operation with significant spill prevention. The one-piece molded spout of the wash jug features a pull-out telescopic tube that extends the filling channel, adapting to the compact installation space inside the dashboard. This solves the inconvenience caused by the concealed installation location and low filling port of traditional wash jugs. At the same time, the limiting structure at the extreme extension end of the telescopic tube effectively prevents it from completely detaching, ensuring stability during use. Combined with the press-type sealing cap, opening and closing requires no additional tools, is quick and easy, and provides a reliable seal, preventing detergent leakage during filling or evaporation and seepage during storage.

[0014] 2. Strong assembly adaptability and high installation stability. The washer reservoir body adopts a combination of multiple mounting points and spring nuts and M6 bolts for fixing. The spring nuts can flexibly compensate for assembly size errors, adapt to the installation accuracy requirements of the instrument panel tube beam bracket, and ensure that the device is firmly connected to the bracket. Even if vibration occurs during vehicle operation, it can prevent the device from loosening or shifting, reducing the probability of abnormal noise. The upper and lower bodies are spliced ​​to form a closed structure, ensuring the sealing of the washer fluid storage and preventing leakage.

[0015] 3. Neat wiring harnesses and pipes improve assembly efficiency. The integrated injection-molded wiring harness fixing bracket of the washer cartridge body can centrally fix the water pipes and washer motor wiring harnesses, avoiding messy tangles of pipes and wiring harnesses. This reduces friction and wear between pipes, wiring harnesses and other components during vehicle operation, extending service life, and makes the interior layout of the dashboard neater, simplifying the vehicle assembly process and reducing assembly time and costs.

[0016] 4. Compact structural design and wide adaptability. The high degree of integration of each component, with the spout and upper body integrally molded and the wiring harness bracket and body integrally injection molded, reduces the number of detachable connectors, making the overall structure of the device compact and small in size, and flexibly adaptable to the interior space layout of different vehicle dashboards; the matching design of the sealing sleeve and washing motor not only ensures the sealing of the motor installation, but also simplifies the motor assembly process, improving the versatility and practicality of the device.

[0017] 5. Excellent reliability and durability. The press-type lid is connected to the spout via a collar, which is simple in structure and has a stable connection, making it less prone to damage. The pull-out design of the telescopic tube combines convenient filling with compact storage, avoiding the problem of easy breakage from a fixed long spout. The overall structural design takes into account core requirements such as sealing, anti-detachment, and neatness, and can maintain stable performance in complex driving environments, extending the overall service life of the device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0021] like Figure 1 , Figure 2 As shown, a convenient filling washing pot device includes an upper washing pot body 1, a lower washing pot body 2, a wire harness fixing bracket 3, a telescopic tube 4, a pot lid 5, and a washing motor 6. The main body 1 of the washing kettle is integrally injection molded with a spout 10. The inner wall of the spout 10 is a smooth cylindrical surface. The telescopic tube 4 is made of wear-resistant plastic material and is coaxially sleeved inside the spout 10 in a pull-out manner. The outer periphery of the extreme extension end of the telescopic tube 4 is provided with an annular limiting step. The annular limiting step forms an axial limiting fit with the inner end face of the spout 10 to prevent the telescopic tube 4 from completely dislodging from the spout 10, while ensuring the smoothness of the pulling process. The lower body 2 of the washing kettle is integrally formed with a protruding platform. The center of the protruding platform is provided with a mounting hole that is compatible with the washing motor 6. The mounting end of the washing motor 6 is fitted into the mounting hole through an interference fit sealing sleeve to achieve a sealed connection between the washing motor 6 and the washing kettle body. The lower body 2 of the washing pot and the upper body 1 of the washing pot are fixedly connected by a hot plate welding process to form a closed washing pot body with a washing liquid storage chamber inside. The outer peripheral wall of the washing pot body has 4 mounting points distributed in the circumferential direction. One mounting point is an embedded hole structure with a spring nut 9 embedded inside to compensate for assembly size errors. The other 3 mounting points are through holes and can be detachably fastened to the instrument panel tube beam bracket by M6 bolts 8 to ensure installation stability. The wire harness fixing bracket 3 is integrally injection molded with the lower body 2 of the washing pot. The wire harness fixing bracket 3 is used to fix the wire harness of the water pipe and the washing motor 6 respectively, so as to avoid the pipe and wire harness from being messy and tangled. The lid 5 is a press-type sealing structure with a silicone sealing gasket embedded on its inner side. The lid 5 is connected to the outer peripheral wall of the spout 10 through an annular collar 5-1 (the lid 5 is connected to the collar 5-1, and the collar 5-1 is installed on the spout 10). The connecting surface of the collar 5-1 and the spout 10 is provided with anti-slip texture, which not only ensures the sealing reliability of the lid 5, but also facilitates quick opening and closing operation.

[0022] In some embodiments, the maximum extension length of the telescopic tube 4 is set to 9cm, which can be adapted to the spatial layout inside the dashboard of a commercial vehicle. When the telescopic tube 4 is pulled out, it forms an axially extending guide channel for filling the washing liquid, which effectively shortens the distance between the filling port and the filling container and reduces the overflow of washing liquid.

[0023] In some embodiments, such as Figure 1 As shown, the outer circumference of the outer end of the spout 10 is integrally formed with an annular limiting protrusion 10-1. The inner diameter of the collar 5-1 is 0.5-1mm smaller than the outer diameter of the limiting protrusion 10-1, and the end face of the limiting protrusion 10-1 fits and cooperates with the silicone sealing gasket on the inner side of the lid 5 to form a double axial sealing structure, which further improves the sealing performance of the lid 5 and prevents the washing liquid from evaporating or leaking.

[0024] In some embodiments, the upper body 1 and the lower body 2 of the washing pot are fixed together by a hot plate welding process, with the welding temperature controlled at 200-220℃ to ensure the structural strength and sealing performance of the weld; furthermore, the welding surface is provided with mutually compatible positioning bosses and positioning grooves, and precise centering is achieved through the positioning structure during welding.

[0025] In some embodiments, the output nozzle of the washing motor 6 is provided with an annular sealing groove on its outer periphery. One end of the water pipe is fixedly sleeved in the sealing groove of the output nozzle by a clamp to achieve a sealed connection. The other end of the water pipe passes through a protective sleeve 7 and then through the front sheet metal. The protective sleeve 7 is made of wear-resistant rubber material and has flared guide openings at both ends. The protective sleeve 7 is tightly sleeved at the contact part between the water pipe and the front sheet metal to isolate the water pipe from the edge of the sheet metal, prevent the water pipe from being worn by the sharp edge of the sheet metal during vehicle operation, and extend the service life of the water pipe.

[0026] In some embodiments, such as Figure 2 As shown, the three mounting points on the washing jug body that are fixed to the instrument panel tube beam bracket by M6 bolts 8 are all designed with oval holes. The length direction of the oval holes is consistent with the extension direction of the instrument panel tube beam, which can absorb dimensional deviations during installation and slight vibration displacements during vehicle operation, thereby improving assembly adaptability and structural stability.

[0027] In some embodiments, the inner wall of the sealing sleeve is provided with at least one annular sealing rib. The cross-section of the annular sealing rib is triangular. The annular sealing rib forms an interference fit with the mounting end face of the washing motor 6. Multiple seals are achieved through the elastic deformation of the sealing rib, effectively preventing the washing liquid from leaking from the motor mounting point.

[0028] In some embodiments, such as Figure 1As shown, the telescopic tube 4 is coaxially arranged along the axial direction of the spout 10, and the telescopic tube 4 is inclined at an angle of 15°-30° with the horizontal plane. This inclination angle is designed according to the spatial orientation of the commercial vehicle dashboard to avoid interference with surrounding components. The opening of the telescopic tube 4 is integrally formed with an outwardly extending horizontal guide port. The horizontal guide port is at a certain angle with the axial direction of the telescopic tube 4, and the inner wall of the horizontal guide port is processed into a smooth arc surface. This can reduce the resistance of the washing liquid flow through the arc surface and avoid the problem of washing liquid stagnation. Through the combination of the inclined arrangement of the telescopic tube and the horizontal guide port, the filling angle of the washing liquid can be optimized. The inclined telescopic tube adapts to the interior space of the dashboard, and the horizontal guide port makes the filling port orientation more in line with the user's normal filling posture (such as the hand operation angle when standing to fill). This makes the liquid flow direction highly compatible with the operation posture, guiding the washing liquid to flow smoothly into the filling channel along the arc surface, effectively reducing the overflow and splashing of washing liquid caused by angle deviation, and further improving the convenience and reliability of the filling operation.

[0029] In a second aspect, this utility model also provides a commercial vehicle, wherein the dashboard of the commercial vehicle has a pre-set mounting cavity adapted to the shape of the convenient filling wash bottle device, and the spatial dimensions of the mounting cavity match the length, width and height parameters of the wash bottle body, ensuring that the device is compactly embedded and does not interfere with other components in the dashboard (such as air conditioning ducts and wiring harness assemblies). The convenient-filling wash bottle device achieves precise fixed connection with the commercial vehicle dashboard tube beam bracket through four mounting points distributed circumferentially on the outer peripheral wall of its wash bottle body. One mounting point is fitted with a spring nut 9, which can compensate for the assembly size error of the dashboard tube beam bracket through the elastic deformation of the spring. The other three mounting points are designed with an oval hole structure and are fastened by M6 bolts 8. The length of the oval hole along the extension direction of the tube beam can absorb slight vibration displacement during vehicle driving. The overall structural design is fully adapted to the dashboard space layout and complex vibration environment of commercial vehicles. The combination of spring nut and oval hole ensures the installation stability of the device for long-term use, and the pull-out design of the telescopic tube 4 solves the problem of inconvenient washing fluid filling caused by the closed internal space of the commercial vehicle dashboard, thus meeting the convenience needs of daily maintenance of commercial vehicles.

[0030] How to use the above-mentioned convenient filling water jug ​​device: S1. When it is necessary to replenish the washing liquid, first remove the lid 5 from the spout 10, and use the collar 5-1 to suspend the lid 5 on one side of the spout 10 to prevent the lid 5 from being lost; then pull the telescopic tube 4 out of the spout 10 until the annular limiting step of the telescopic tube 4 contacts the inner end face of the spout 10 (maximum extension length 9cm), at which point the horizontal guide port is in a horizontal state; then align the outlet of the washing liquid container with the horizontal guide port, and slowly inject the washing liquid along the guide port. The washing liquid flows into the storage cavity of the washing pot body through the telescopic tube 4 and the spout 10; after filling, push the telescopic tube 4 back into the spout 10 to reset it, and then put the lid 5 back on the spout 10, pressing it until the silicone sealing gasket and the limiting protrusion 10-1 are in contact; S2. During vehicle operation, the washing motor 6 can deliver the washing liquid in the storage chamber to the end of the vehicle that needs to be used (such as the windshield) through the water pipe. If it is necessary to inspect or replace the water pipe / wiring harness, the water pipe can be removed from the wiring harness fixing bracket 3 or the wiring harness can be pulled out from the wiring hole for operation. When it is necessary to disassemble the device, unscrew the M6 ​​bolts 8 at the 3 mounting points to remove the washing tank body from the instrument panel tube beam bracket. The spring nut 9 is removed along with the body to facilitate subsequent maintenance or replacement of parts.
