Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck technology, and more specifically, to a washer water tank assembly. Furthermore, this utility model also relates to a truck including the aforementioned washer water tank assembly. Background Technology

[0002] The gap between the front sheet metal and the front cover of heavy trucks is small, which makes it inconvenient to arrange large-capacity washer water tank assemblies. Therefore, in the design, most of them adopt a small water tank assembly design or place the water tank assembly on the frame.

[0003] However, the small water tank assembly has a small inherent volume and can hold less cleaning water. During use, it needs to be refilled frequently. If the cleaning water is insufficient due to failure to refill in time, it will affect the driver's vision and pose a safety hazard.

[0004] Placing the water tank assembly on the frame would obstruct the filling port due to the lower frame position, making it inconvenient to add cleaning water.

[0005] In summary, how to solve the problem of small capacity of existing water tank assemblies in heavy-duty trucks or inconvenient filling of cleaning water is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a washing machine water tank assembly, which uses a split design for the water tank body and the filling nozzle to fix the large-capacity water tank body to the vehicle frame, while fixing the filling nozzle to the front sheet metal of the cab, thereby ensuring the water tank capacity and ensuring convenient filling of washing water.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this utility model is to provide a washer water tank assembly. Through the separate design of the water tank body and the filling nozzle, the large-capacity water tank body is fixed to the vehicle frame, while the filling nozzle is fixed to the front sheet metal of the cab, thereby ensuring the water tank capacity and ensuring convenient filling of cleaning water.

[0035] Another core aspect of this utility model is to provide a truck that includes the aforementioned washer and kettle assembly, which has the same technical solution and can achieve the same effect.

[0036] Please refer to Figures 1-5 A washer kettle assembly, comprising:

[0037] The water bottle body 1 has a first connector on its outer wall for fixing to the frame;

[0038] The filling nozzle 6 is designed separately from the water tank body 1, and the outer wall is provided with a second connector for fixing to the front sheet metal of the cab. The installation height of the filling nozzle 6 is greater than the installation height of the water tank body 1, and the filling nozzle 6 is connected to the water inlet of the water tank body 1 through the hose 4.

[0039] In use, the water bottle body 1 is fixed on the frame by the fastener and the first connector. There is enough space on the frame to arrange the large-capacity water bottle body 1. Therefore, the amount of cleaning water stored in the water bottle body 1 can be effectively increased, and the problem of needing to frequently add cleaning water is solved.

[0040] By fixing the fastener and the second connector, the filling nozzle 6 is set on the front sheet metal of the cab, so that it has a high installation position and will not be blocked, which facilitates the filling of cleaning water. Since its installation height is greater than that of the water tank body 1, it can achieve rapid filling of cleaning water by means of gravity.

[0041] Meanwhile, the filling nozzle 6 is connected to the water tank body 1 by a hose 4. The flexibility of the hose 4 is used to eliminate the problem of water tank deformation caused by relative jump between the frame and the front bulkhead sheet metal of the cab.

[0042] In some embodiments, the water tank body 1 is fixedly installed in a location with a large amount of space inside the vehicle body, and / or the filling nozzle 6 is fixedly installed in other locations that facilitate the filling of cleaning water, all of which fall within the scope of protection of this application.

[0043] In some embodiments, a neck tube 11 is provided at the water inlet of the kettle body 1. The diameter of the neck tube 11 is larger than the diameter of the hose 4, and the horizontal cross-sectional area of ​​the neck tube 11 is smaller than the horizontal cross-sectional area of ​​the kettle body 1.

[0044] like Figure 2As shown, a neck tube 11 is provided on the water bottle body 1 for easy connection with the hose 4; and by designing the diameter or cross-sectional area of ​​the neck tube 11, the filling speed can be increased when adding cleaning water, and the probability of impact water flow entering the hose 4 can be reduced when the vehicle is moving, thus reducing the vibration of the hose 4.

[0045] In some embodiments, the neck tube 11 is integrally formed with the kettle body 1, and the center line of the neck tube 11 and the center line of the water inlet of the kettle body 1 form an acute angle.

[0046] like Figure 2 As shown, the neck tube 11 and the kettle body 1 are produced by integral injection molding, which can effectively improve production efficiency, simplify the production process and reduce production costs. At the same time, the inclined neck tube 11 will rub against the side wall of the neck tube 11 to consume kinetic energy when the water flows upward, thereby slowing down its upward movement trend and further reducing the probability of cleaning water overflowing the kettle body 1.

[0047] In some embodiments, the end of the neck tube 11 is connected to the hose 4 via an adapter 2. The large-diameter end of the adapter 2 is connected to the neck tube 11 via a thread. The small-diameter end of the adapter 2 is provided with a first groove on the outside. The hose 4 is inserted into the outside of the first groove and is fastened and fixed by a first clamp 3.

[0048] like Figure 1 and Figure 3 As shown, the adapter 2 is a stepped sleeve structure. Its large-diameter end is connected to the neck tube 11 and is connected by a thread for easy and quick assembly. Its small-diameter end is connected to the hose 4. A first groove is provided at the small-diameter end. After the hose 4 is inserted into the small-diameter end, the first clamp 3 is used to clamp it at the first groove, which firmly fixes the hose 4 to the outside of the small-diameter end, thereby effectively preventing the hose 4 from separating from the small-diameter end and ensuring a stable connection between the hose 4 and the kettle body 1.

[0049] In some embodiments, a sealing gasket 23 is provided at the stepped surface of the inner cavity of the adapter 2, and a limit ring 22 and a check plate 21 are provided in the small diameter end. One end of the check plate 21 is fixedly connected to the inner wall of the adapter 2, and the limit ring 22 is used to restrict the check plate 21 from opening in the reverse direction.

[0050] like Figure 4 As shown, a sealing gasket 23 is provided at the inner cavity step surface of the adapter 2. When the external thread at the end of the neck tube 11 is engaged with the internal thread at the large diameter end of the adapter 2, the neck tube 11 is inserted into the large diameter end and abuts against the sealing gasket 23, causing the sealing gasket 23 to deform and seal, thereby improving the sealing performance between the neck tube 11 and the adapter 2.

[0051] Meanwhile, a check plate 21 is installed inside the adapter 2. When the water in the kettle body 1 flows upward, it first impacts the side wall of the neck tube 11, and then impacts the check plate 21. The check plate 21 flips upward under the action of the water flow and abuts against the limit ring 22 to limit and close the internal channel of the adapter 2, thereby preventing the water from entering the hose 4.

[0052] When water needs to be added to the kettle body 1, the water flows through the hose 4 into the small diameter end of the adapter 2, impacts the check plate 21, causing the check plate 21 to flip downwards, opening the internal channel of the adapter 2, thus preventing interference with the water flow.

[0053] In some embodiments, the filling nozzle 6 is a funnel structure with a second groove at its small diameter end, and the hose 4 is sleeved in the second groove and fastened by the second clamp 5.

[0054] like Figure 5 As shown, the filling nozzle 6 adopts a funnel structure, which facilitates the filling of cleaning water. At the same time, a second groove is provided at the small diameter end of the filling nozzle 6. After the hose 4 is sleeved on the small diameter end, the second clamp 5 is used to fix the hose 4 in the second groove to prevent the hose 4 from falling off.

[0055] In some embodiments, the large-diameter end of the filling nozzle 6 is provided with an openable and closable cap 61 for sealing the filling nozzle 6;

[0056] By setting a cap 61 at the large-diameter end of the filling nozzle 6, foreign matter can be effectively prevented from entering.

[0057] In some embodiments, one side of the cap 61 is integrally formed with the filling nozzle 6 or is hinged to it.

[0058] Using a cap 61 integrally formed with the filling nozzle 6 helps to reduce assembly steps, improve the integration of the filling nozzle 6 and the cap 61, and effectively prevent the cap 61 from being lost.

[0059] A cap 61 with a hinge or other type of cap 61 that is snapped onto the large-diameter end of the filling nozzle 6 can be designed separately and manufactured using a different process than that used for the filling nozzle 6, in order to improve the sealing and mechanical properties of the cap 61. This is also within the scope of protection of this application.

[0060] In some embodiments, the sum of the distance between the mounting point of the water bottle body 1 on the frame and the mounting point of the filling nozzle 6 on the front bulkhead sheet metal and the maximum relative runout is not greater than the length of the hose 4.

[0061] By designing the length of the hose 4, when the installation point of the kettle body 1 and the installation point of the spout 6 reach their maximum distance, there will be no pulling force between the spout 6 and the kettle body 1 and the hose 4, thereby preventing the hose 4 from falling off.

[0062] In addition to the washer-kettle assembly disclosed in the above embodiments, this utility model also provides a truck including the above-mentioned washer-kettle assembly. The structure of other parts of the truck is described in the prior art and will not be repeated here.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0064] The washer and water tank assembly and truck provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
