Description

Technical Field

[0001] The present invention relates to the technical field of automotive electric water pumps, and particularly to an automotive electric water pump provided with a joint anti-loosening docking structure. Background Art

[0002] An automotive electric water pump is a device for water circulation, cooling, or on-vehicle water supply systems. During operation, it needs to be docked with the output end of the water pump through a reserved supply pipeline for liquid conduction work. Its quality determines the quality of the overall automotive water supply state. For example, a patent for an automotive electric water pump with the publication number CN114109579B belongs to the technical field of automotive water pumps. An automotive electric water pump includes a pump body, a pump cover, a stator, a water isolation sleeve, a rotating shaft, a rotor, and a controller. The pump cover is connected to the pump body. The stator is inserted into the pump body. The water isolation sleeve is inserted into the stator. The rotating shaft is arranged in the water isolation sleeve and fixedly connected to the water isolation sleeve. The rotor is sleeved on the rotating shaft. A controller bracket is arranged on the side of the stator away from the pump cover. Without substantially increasing the axial length of the automotive electric water pump, active heat dissipation of the controller is achieved. At the same time, this solution reduces the use of sealing rings and reduces the risk of liquid leakage of the automotive electric water pump. Another example is a patent for an automotive electric water pump with the publication number CN110017288B, which belongs to the technical field of automotive electric water pumps. An electric motor stator and an electric motor rotor installed in the motor housing, the electric motor stator being a tooth-slot structure; an impeller connected to the front end of the electric motor rotor; a volute casing covering the front end of the motor housing and provided with an impeller cavity for accommodating the impeller, the volute casing having a cut-off tongue; wherein the cut-off tongue does not coincide with any tooth slot in the tooth-slot structure; this can solve the problem of relatively high noise of existing automotive electric water pumps; since the cut-off tongue and the tooth-slot structure are no longer opposite each other, the excitation frequency of the blades will not resonate with the torque frequency generated by the motor part due to the tooth-slot effect, so the noise generated by the resonance caused by the mutual excitation of the excitation frequency and the torque frequency can be eliminated, thereby reducing the noise of the automotive electric water pump. For example, a patent for an automotive electric water pump with the publication number CN108223395A, the automotive electric water pump includes a pump housing, an electric motor connected to the pump housing through bearings, and an electric motor housing arranged on the electric motor and connected to the pump housing; the materials of the pump housing and the electric motor housing are plastic. By using a pump housing and an electric motor housing made of lightweight plastic instead of those made of aluminum alloy, the purpose of reducing the weight burden of the vehicle to save fuel consumption is achieved; the assembly process of the automotive electric water pump is simplified to achieve lower assembly costs and quality failure risks. Most of the above-mentioned existing technologies have improved their overall structure. However, during the operation of the existing automotive electronic water pump, due to the high pressure generated during the water pump transmission process, the conventional docking pipeline state is very easy to loosen due to the long-term influence of the impact force, which in turn leads to water leakage at the docking end during long-term operation, and thus has certain usage limitations.

[0006] Furthermore, a reserved arc groove is opened on the outer side of the output end of the electronic water pump body, and the reserved arc groove corresponds to the position of the limit docking vertical piece. The outer side of the inclined reserved docking piece is docked with a docking resistance piece, and the docking resistance piece is nested and docked along the inner side of the external docking pipe body.

[0007] Furthermore, when the abutting docking float contacts the liquid transmission force, a sliding structure is formed along the transverse guide groove, and the abutting docking float drives the inclined reserved docking piece to move outward synchronously, and the inclined reserved docking piece simultaneously applies pressure to the contacting limit docking vertical piece.

[0008] Further, the limiting and docking vertical member moves downward along the inner side of the guiding reserved groove through a return spring, and the external docking pipeline body forms a positioning structure with the reserved arc groove on the outer side of the output end of the electronic water pump body through the limiting and docking vertical member.

[0009] Further, an auxiliary anti-loosening structure is arranged on the inner side of the external docking pipeline body to seal and dock the external docking pipeline body and the output end of the electronic water pump body through the auxiliary anti-loosening structure; the auxiliary anti-loosening structure is provided with a docking internal corrugated liquid bag, and the docking internal corrugated liquid bag is arranged at the inner end of the external docking pipeline body, and the docking internal corrugated liquid bag is mutually attached to the outer side of the docking contact piece; a vertical guiding groove is opened on the inner side of the external docking pipeline body, and an internal locking member is nested and installed inside the vertical guiding groove, and a vertical docking corrugated liquid bag is adhesively connected to the outer end of the internal locking member.

[0010] Further, a reserved supply pipe penetrates through the outer side of the vertical docking corrugated liquid bag, and the reserved supply pipe penetrates along the inner side of the external docking pipeline body, and the end of the reserved supply pipe is mutually connected to the inner side of the docking internal corrugated liquid bag; a reserved fitting air bag assembly is adhesively connected to the outer side of the internal locking member, and the upper end of the reserved fitting air bag assembly is mutually docked with the inner wall of the external docking pipeline body.

The vertically expanding vertical docking corrugated liquid sac pushes the outer internal locking piece to move upwards, so that the symmetrically distributed internal locking pieces apply pressure adaptively to the inner wall of the output end of the electronic water pump body for locking work, and cooperate with the outer self-locking structure to achieve internal and external double positioning processing, thus stably ensuring the transmission stability under its high-strength working state; Furthermore, during the process of the outer side of the internal locking piece being mutually fitted and positioned with the inner wall of the output end of the electronic water pump body, the outer side of the internal locking piece will move upwards and apply pressure to the contact reserved fitting airbag assembly synchronously, so that the compressed and deformed reserved fitting airbag assembly fills and seals the docking part between the output end of the electronic water pump body and the external docking pipeline body, avoiding the phenomenon of water seepage and leakage during liquid transmission, and improving the practicability of the device.
