Detailed Description of the Embodiment

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the drawings.

[0023] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods that are consistent with some aspects of the present invention as detailed in the appended claims.

[0024] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and cannot be construed as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The expansion tank is used to regulate the pressure of the vehicle cooling system and buffer the change in the volume of the antifreeze. In existing vehicle models, the exhaust port of the expansion tank is set at the mouth of the expansion tank, and the antifreeze remains on the surface of the expansion tank body, which is not beautiful and is easily misjudged as antifreeze leakage. To solve this problem, the exhaust port of the expansion tank is designed at the bottom of the expansion tank body, so that the exhaust of the expansion tank of the new vehicle models (EV platform, PHEV platform, HEV platform) is drained downward through the internal drainage groove. When the existing antifreeze filling gun fills the expansion tank of the existing vehicle models, an end face sealing method is adopted. However, since the exhaust port of the expansion tank of the new vehicle models is designed inside the mouth of the tank, the existing filling gun cannot block the exhaust port, resulting in leakage when the filling equipment evacuates and fills the expansion tank of the new vehicle models, and it cannot meet the antifreeze filling of the expansion tank assembly of the new vehicle models.

[0027] To solve the above problems, please refer to Figures 1 to 3As shown in the figure, the present utility model proposes an antifreeze filling gun for automobiles. The antifreeze filling gun for automobiles includes a filling gun body 1. One end of the filling gun body 1 is connected to an antifreeze storage tank, and the other end is provided with a filling gun head 2. The filling gun head 2 includes a first connecting portion 21, a second connecting portion 22, and a filling pipe 23. One end of the first connecting portion 21 is connected to the filling gun body 1, and the other end is connected to the second connecting portion 22. The filling pipe 23 is connected to the second connecting portion 22 and is vertically arranged relative to the second connecting portion 22. The diameter of the first connecting portion 21 is greater than that of the second connecting portion 22. A first seal 3 is provided on the surface of the first connecting portion 21 facing the second connecting portion 22, and a second seal 4 is provided on the peripheral side of the second connecting portion 22. Among them, the first seal 3 is used for sealing the filling gun head 2 and the first expansion tank 7, and the second seal 4 is used for sealing the filling gun head 2 and the second expansion tank 8.

[0028] Furthermore, both the first seal 3 and the second seal 4 are made of rubber material, which has the characteristics of aging resistance, corrosion resistance, and good elasticity. The first seal 3 is an O-ring, and the second seal 4 is cylindrical, which is convenient for the second seal 4 to be sleeved on the second connecting portion 22, facilitating disassembly and replacement. The filling gun body 1 is also provided with a vacuum extraction valve and a filling valve. The air in the first expansion tank 7 or the second expansion tank 8 is extracted through the vacuum extraction valve to form a vacuum environment, which is convenient for the filling of antifreeze. When the filling valve is started, the filling gun can perform the antifreeze filling work.

[0029] In an alternative embodiment, as Figure 1 and Figure 3 shown, the first seal 3 is bonded to the surface of the first connecting portion 21 facing the second connecting portion 22. The first seal 3 is fixedly installed on the first connecting portion 21 by using the bonding method. At the same time, the size of the first seal 3 is consistent with the size of the mouth of the first expansion tank 7, ensuring that when using the filling gun to fill antifreeze, the first seal 3 contacts the end face of the mouth, forming an end face sealing method, so that the first seal 3 completely seals the mouth. At the same time, using the characteristics of the first seal 3 itself, the sealing performance between the first connecting member and the first expansion tank 7 is further improved. In addition, a limiting groove can be opened on the surface of the first connecting portion 21 facing the second connecting portion 22, and the limiting groove is used to install the first seal 3.

[0030] In an alternative embodiment, the filling gun head 2 is an integrally formed structure. The first connecting portion 21, the second connecting portion 22, and the filling pipe 23 are made by an integrally formed process, which has high connection strength, good sealing performance, and low cost.

[0031] In an alternative embodiment, as Figure 1 andFigure 3 As shown, the second seal 4 is sleeved on the second connecting portion 22. A plurality of the second seals 4 are provided, and the plurality of second seals 4 are distributed along the length direction of the second connecting portion 22. The second seal 4 is installed on the second connecting portion 22 in a sleeved manner. At the same time, a plurality of second connecting portions 22 are provided, so that the contact surface between the two is large, and the second seal 4 is not easily detached from the second connecting portion 22, improving the connection stability between the two. In this embodiment, three second seals 4 are provided. After the filling gun is inserted into the mouth of the second expansion tank 8, the second connecting portion 22 is inserted into the exhaust port of the second expansion tank 8. At this time, the outer diameter of the second seal 4 is close to the inner diameter of the exhaust port, so that the second seal 4 abuts against the inner wall of the exhaust port, improving the sealing performance between the filling gun and the second expansion tank 8 during the filling process.

[0032] In an alternative embodiment, as Figure 1 and Figure 2 shown, the filling gun body 1 is provided with an electric gripper 5, and the electric gripper 5 is arranged on the periphery of the filling gun head 2. After the filling gun is inserted into the expansion tank, the electric gripper 5 clamps the mouth of the tank, so that the filling gun is stably placed, avoiding the filling gun from coming out during the filling process, and at the same time saving labor and not requiring employees to hold the filling gun by hand.

[0033] In an alternative embodiment, as Figure 1 shown, one end of the filling gun body 1 away from the filling gun head 2 is provided with a cylinder 6, and the cylinder 6 is electrically connected to the electric gripper 5 for controlling the electric gripper 5 to approach or move away from each other. Using the cylinder 6 as the driving source, the cylinder 6 drives the electric gripper 5 to approach or move away from each other to improve the connection strength between the filling gun and the expansion tank during filling or to facilitate the removal of the filling gun from the expansion tank after filling, with a high degree of automation and saving labor costs.

[0034] In an alternative embodiment, as Figure 1 shown, the electric gripper 5 includes a connecting section 51 and a clamping section 52. One end of the connecting section 51 is connected to the filling gun body 1, and the other end is connected to the clamping section 52. The end of the clamping section 52 away from the connecting section 51 is provided with a limiting end 53 in the direction of the filling gun head 2, and the limiting end 53 is used to limit the movement of the filling gun body 1. The first expansion tank 7 or the second expansion tank 8 is provided with a raised edge corresponding to the limiting end 53, so that after the electric grippers 5 approach each other, the limiting end 53 abuts against the raised edge, further improving the connection strength between the two.

[0035] In an alternative embodiment, four electric grippers 5 are provided and are equidistantly distributed on the periphery of the filling gun head 2. The four electric grippers 5 clamp the filling gun to the expansion tank from multiple aspects, improving the connection strength between the two.

[0036] The present utility model also provides a filling device, which includes the above-mentioned antifreeze filling gun for automobiles.

[0037] In summary, the filling gun head 2 of the filling gun is provided with a first seal 3 and a second seal 4, so that the filling gun can have different sealing methods, cooperate with the expansion tanks of existing models and new models, reduce the types of filling guns and the time cost of changing guns, avoid repair due to the inability to fill the expansion tank of new models, and improve work efficiency.
