Description

Technical Field

[0001] The present invention relates to the technical field of automobile electronic water pumps, in particular to an automobile electronic water pump provided with a joint anti-loosening docking structure. Background Art

[0002] The automotive electronic water pump is a device used for water circulation, cooling or vehicle water supply systems. During operation, it needs to be connected to the output end of the water pump through a reserved supply pipe to conduct liquid. The quality of the water pump determines the quality of the overall vehicle water supply.

[0003] For example, the patent with announcement number CN114109579B discloses an automotive electronic water pump, which belongs to the technical field of automotive water pumps. The automotive electronic water pump comprises a pump body, a pump cover, a stator, a water-blocking 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-blocking sleeve is inserted into the stator, the rotating shaft is disposed in and fixedly connected to the water-blocking sleeve, the rotor is sleeved on the rotating shaft, and a controller bracket is provided on the side of the stator away from the pump cover. This solution achieves active heat dissipation of the controller without substantially increasing the axial length of the automotive electronic water pump. At the same time, this solution reduces the use of sealing rings, thereby reducing the risk of leakage in the automotive electronic water pump.

[0004] Another example is a patent with publication number CN110017288B, which discloses an automotive electronic water pump belonging to the technical field of automotive electronic water pumps. The patent comprises a motor stator and a motor rotor installed in a motor housing, wherein the motor stator has a tooth slot structure; an impeller connected to the front end of the motor rotor; a volute covering the front end of the motor housing and provided with an impeller cavity for accommodating the impeller, wherein the volute has a partition tongue; wherein the partition tongue does not overlap with any tooth slot on the tooth slot structure; and the problem of high noise in existing automotive electronic water pumps can be solved; since the partition tongue and the tooth slot structure are no longer opposite each other, the excitation frequency of the blades will not mutually excite and resonate with the torque frequency generated by the tooth slot effect of the motor part, thereby eliminating the noise caused by the resonance caused by the mutual excitation of the excitation frequency and the torque frequency, thereby reducing the noise of the automotive electronic water pump;

[0005] For example, the patent with publication number CN108223395A describes an automotive electronic water pump comprising a pump housing, a motor connected to the pump housing via bearings, and a motor housing mounted on the motor and connected to the pump housing. The pump housing and motor housing are made of plastic. By replacing aluminum alloy pump and motor housings with lightweight plastic, the vehicle's weight is reduced, saving fuel. The assembly process for the automotive electronic water pump is simplified, reducing assembly costs and the risk of quality failure.

[0006] 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 pipe state is very likely to become loose due to the long-term influence of the impact force, which in turn causes the docking end to leak during long-term operation, and thus has certain usage limitations. Summary of the Invention

[0011] Furthermore, a reserved arc groove is opened on the outside of the output end of the electronic water pump body, and the reserved arc groove corresponds to the position of the limit docking vertical part. The outer side of the inclined reserved docking part 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.

[0012] 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 surface reserved docking piece to move outward synchronously, and the inclined surface reserved docking piece synchronously applies pressure to the contacting limit docking vertical piece.

[0013] Furthermore, the position-limiting docking vertical member moves downward along the inner side of the guide reserved groove through a reset spring, and the external docking pipe body forms a positioning structure through the position-limiting docking vertical member and the reserved arc groove outside the output end of the electronic water pump body.

[0014] Furthermore, an auxiliary anti-loosening structure is provided on the inner side of the external docking pipe body, and the sealing docking between the external docking pipe body and the output end of the electronic water pump body is performed through the auxiliary anti-loosening structure; the auxiliary anti-loosening structure is provided with a docking built-in corrugated liquid capsule, and the docking built-in corrugated liquid capsule is provided at the inner end of the external docking pipe body, and the docking built-in corrugated liquid capsule and the outer side of the docking resistance piece are fitted with each other; a vertical guide groove is opened on the inner side of the external docking pipe body, and a built-in locking piece is nested and installed on the inner side of the vertical guide groove, and the outer end of the built-in locking piece is adhesively connected to the vertical docking corrugated liquid capsule.

[0015] Furthermore, a reserved supply pipe is passed through the outer side of the vertical docking corrugated liquid bag, and the reserved supply pipe passes through the inner side of the external docking pipe body, and the end of the reserved supply pipe is connected to the inner side of the docking built-in corrugated liquid bag; the outer side of the built-in locking part is adhesively connected to a reserved fitting airbag assembly, and the upper end of the reserved fitting airbag assembly is docked with the inner wall of the external docking pipe body.

[0017] Furthermore, the outer side of the built-in locking part corresponds to the inner wall of the output end of the electronic water pump body, and during the upward movement of the outer side of the built-in locking part, pressure is simultaneously applied to the contacted reserved fitting airbag component.

[0019] The automobile electronic water pump provided with a joint anti-loosening docking structure is provided with a drainage self-positioning structure, which performs self-locking work between the output end of the electronic water pump body and the external docking pipe body through the drainage self-positioning structure. When liquid transmission is performed inside the electronic water pump body, the high-intensity water flow will push the resistance docking float on the inner side of the external docking pipe body to move outward, thereby driving the inclined surface reserved docking piece docking with the outer side of the resistance docking float to move inward synchronously, and synchronously pressurizing the contacting limit docking vertical piece, so that the external docking pipe body forms a self-positioning structure with the reserved arc groove on the outer side of the output end of the electronic water pump body through the limit docking vertical piece, thereby adaptively performing self-locking work during water pump transmission, and avoiding the conventional docking pipeline state that is very easy to loosen due to the long-term influence of impact force;

[0020] Furthermore, an auxiliary anti-loosening structure is provided, which performs the sealing docking work between the external docking pipe body and the output end of the electronic water pump body through the auxiliary anti-loosening structure. As the inclined reserved docking piece is forced to move inward, it will cooperate with the docking resistance piece to apply pressure to the docking built-in corrugated liquid bag in contact, so that it can supply the liquid to the inside of the vertical docking corrugated liquid bag through the reserved supply pipe. The vertical docking corrugated liquid bag that expands vertically pushes the outer built-in locking piece to move upward, so that the symmetrically distributed built-in locking piece is forced to adaptively lock the inner wall of the output end of the electronic water pump body, and cooperates with the outer self-locking structure to realize internal and external dual positioning processing, thereby stably ensuring its transmission stability under high-intensity working conditions;

[0021] Furthermore, during the process of the outer side of the built-in locking part and the inner wall of the output end of the electronic water pump body being fitted and positioned with each other, the outer side of the built-in locking part will move upward and synchronously apply pressure to the reserved fitting airbag component in contact, so that the reserved fitting airbag component that is deformed under pressure can fill and seal the joint between the output end of the electronic water pump body and the external docking pipe body, avoiding water seepage and leakage during liquid transmission, thereby improving the practicality of the device.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-9 The present invention provides the following technical solution: an automotive electronic water pump with a joint anti-loosening docking structure, comprising an electronic water pump body 1, an external docking pipe body 2, a horizontal guide groove 3, a contact docking float 4, a sloped reserved docking piece 5, a limit docking vertical piece 6, a return spring 7, a reserved arc groove 8, a docking contact piece 9, a docking built-in corrugated liquid bag 10, a reserved supply pipe 11, a vertical docking corrugated liquid bag 12, a built-in locking piece 13, a reserved fitting airbag assembly 14, a guide reserved groove 15, and a vertical guide groove 16;

[0034] The output end of the electronic water pump body 1 is provided with an external connecting pipe body 2, and the external connecting pipe body 2 and the electronic water pump body 1 are threadedly connected;

[0035] A transverse guide groove 3 is provided on the inner side of the external docking pipe body 2, and a resistance docking float 4 is provided on the inner side of the transverse guide groove 3, and the resistance docking float 4 is docked with the inner side of the external docking pipe body 2. A guide reserved groove 15 is provided on the inner side of the external docking pipe body 2, and a bevel reserved docking piece 5 is nested and installed on the inner side of the guide reserved groove 15, and the bevel reserved docking piece 5 and the resistance docking float 4 are docked with each other. A drainage self-positioning structure is provided between the electronic water pump body 1 and the external docking pipe body 2, and the drainage self-positioning structure is used to self-lock the output end of the electronic water pump body 1 and the external docking pipe body 2. The drainage self-positioning structure is provided with a limited docking vertical member 6, which is nested and docked inside the guide reserved groove 15 and docked with the inner end of the external docking pipe body 2. A return spring 7 is fixedly connected to the outer side of the limited docking vertical member 6, and the return spring 7 docks with the inner side of the guide reserved groove 15. A reserved arcuate groove 8 is provided on the outer side of the output end of the electronic water pump body 1, and the reserved arcuate groove 8 corresponds to the position of the limited docking vertical member 6. The outer side of the inclined reserved docking member 5 is docked with a docking resistance piece 9, and the docking resistance piece 9 is nested and docked along the inner side of the external docking pipe body 2. When the resistance docking float 4 contacts the liquid transmission force, it forms a sliding structure along the horizontal guide groove 3, and the resistance docking float 4 drives the inclined reserved docking member 5 to move outward synchronously, and the inclined reserved docking member 5 simultaneously applies pressure to the contacting limited docking vertical member 6.

[0036] The limiting docking vertical piece 6 moves downward along the inner side of the guide reserved groove 15 through the return spring 7, and the external docking pipe body 2 forms a positioning structure with the reserved arc groove 8 on the outer side of the output end of the electronic water pump body 1 through the limiting docking vertical piece 6. When liquid transmission is carried out inside the electronic water pump body 1, the high-intensity water flow will push the resistance docking float 4 on the inner side of the external docking pipe body 2 to move outward, thereby driving the inclined reserved docking piece 5 docking with the outer side of the resistance docking float 4 to move inward synchronously, and simultaneously applying pressure to the contacting limiting docking vertical piece 6, so that the external docking pipe body 2 forms a self-positioning structure with the reserved arc groove 8 on the outer side of the output end of the electronic water pump body 1 through the limiting docking vertical piece 6, thereby adaptively performing self-locking work during the water pump transmission process.

[0037] Example 2: Based on Example 1, an auxiliary anti-loosening structure is also disclosed, and its specific structure is as follows:

[0038] An auxiliary anti-loosening structure is provided on the inner side of the external connecting pipe body 2, and the sealing connection between the external connecting pipe body 2 and the output end of the electronic water pump body 1 is performed through the auxiliary anti-loosening structure;

[0039] The auxiliary anti-loosening structure is equipped with a docking internal corrugated liquid sac 10, which is located at the inner end of the external docking pipe body 2 and is in contact with the outer side of the docking abutment piece 9. A vertical guide groove 16 is provided on the inner side of the external docking pipe body 2, and a built-in locking member 13 is nested and installed inside the vertical guide groove 16. The outer end of the built-in locking member 13 is bonded to the vertical docking corrugated liquid sac 12. A reserved supply tube 11 runs through the outer side of the vertical docking corrugated liquid sac 12 and extends along the inner side of the external docking pipe body 2. The end of the reserved supply tube 11 is connected to the inner side of the docking internal corrugated liquid sac 10. A reserved contact airbag assembly 14 is bonded to the outer side of the built-in locking member 13, and the upper end of the reserved contact airbag assembly 14 is bonded to the inner wall of the external docking pipe body 2.

[0040] The outer side of the built-in locking piece 13 corresponds to the inner wall of the output end of the electronic water pump body 1, and the outer side of the built-in locking piece 13 is pressed synchronously on the reserved fitting airbag component 14 in contact during the upward movement. The reserved fitting airbag component 14 that is deformed under pressure fills and seals the joint between the output end of the electronic water pump body 1 and the external docking pipe body 2; as the inclined reserved docking piece 5 is forced to move inward, it will cooperate with the docking resistance piece 9 to pressurize the docking built-in corrugated liquid capsule 10 in contact, so that it can supply the vertical docking corrugated liquid capsule 12 through the reserved supply pipe 11, and push the outer built-in locking piece 13 upward through the vertically expanded vertical docking corrugated liquid capsule 12. The symmetrically distributed built-in locking parts 13 are subjected to force and adaptively lock the inner wall of the output end of the electronic water pump body 1, and cooperate with the outer self-locking structure to realize internal and external dual positioning processing, thereby stably ensuring its transmission stability under high-intensity working conditions. During the process of mutual fit and positioning between the outer side of the built-in locking part 13 and the inner wall of the output end of the electronic water pump body 1, the outer side of the built-in locking part 13 will move upward and synchronously apply pressure to the contacted reserved fitting airbag component 14, so that the compressed and deformed reserved fitting airbag component 14 fills and seals the joint between the output end of the electronic water pump body 1 and the external docking pipe body 2, avoiding water seepage and leakage during liquid transmission.
