Description

Technical Field

[0001] This utility model relates to the field of electronic water pump technology, specifically to an assembly structure for an automotive electronic water pump. Background Technology

[0002] New energy vehicles require independent cooling for their power systems. Traditional mechanical water pumps lose their power source and must adopt an electric drive solution. New energy vehicles are limited by the limited installation space or need to avoid certain locations, so they cannot use axial screws evenly on the upper surface of the electronic water pump to fix the pump cover and pump housing.

[0003] A car electronic water pump with authorization announcement number CN221838551U includes a water pump mechanism. The water pump mechanism includes: a base plate, a motor fixedly mounted on the upper end surface of the base plate, a water pump body fixedly mounted on the output end of the motor, and a fixing component provided on the outer wall of the water pump body; the fixing component includes: a lower fixing plate, the bottom of the lower fixing plate being fixedly connected to the upper end surface of the base plate, and an upper fixing plate being provided on the upper end surface of the lower fixing plate. By setting the fixing component, it is convenient for workers to fix the water pump body during use. This design eliminates the need for workers to fix the upper and lower fixing plates with fixing bolts. During disassembly, workers do not need to remove fixing bolts one by one, reducing disassembly time and improving work efficiency. However, this water pump assembly structure requires screws to be tightened at the top, which is easily limited by the limited installation space for current car electronic water pump installations, and the overall structure of the fixing component is large and has poor adaptability.

[0004] To address the aforementioned issues, an assembly structure for an automotive electronic water pump is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an assembly structure for an automotive electronic water pump, which solves the problem that the existing water pump assembly structure in the background technology requires screws to be tightened at the top. For the installation of current automotive electronic water pumps, this is easily limited by the limited installation space, and the water pump is round, so there may be a problem of directional deviation after fixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for an automotive electronic water pump, comprising a water pump structural component, a fixed base fitted to the lower end of the water pump structural component, a steering clamp connecting the fixed base and the water pump structural component, two sets of steering clamps arranged side by side, the water pump structural component comprising a pump housing, a limit ring fixedly provided on one side of the pump housing, a straight groove formed on one side of the limit ring, the fixed base comprising a positioning frame fitted to the straight groove, the steering clamp being inserted through the positioning frame, the steering clamp comprising a connected clamp ring and a screw assembly, one end of the clamp ring being inserted into the screw assembly, a rotating screw rotatably disposed in the screw assembly engaging with the clamp ring, and an anti-tilting assembly fixedly provided on one side of the clamp ring.

[0007] Preferably, the water pump structural component further includes an end cap provided at one end of the pump housing, an external wire is connected to one side of the end cap, and the pump housing and the end cap are fixed together by screws.

[0008] Preferably, a pump frame is provided on one side of the pump casing, and an impeller is built into the pump frame.

[0009] Preferably, a motor is fixedly installed inside the pump casing on one side corresponding to the end cover, the impeller is located at the output end of the motor, and the external wire is connected to the motor.

[0010] Preferably, the fixed base further includes a base component fixedly disposed at the lower end of the positioning frame.

[0011] Preferably, the positioning frame has an arc-shaped sleeve hole for inserting a clamping ring.

[0012] Preferably, the anti-tilting kit is fixed on the side where the clamp ring and the screw kit are connected.

[0013] Preferably, one side of the clamp ring has a groove aligned with the rotating screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides an assembly structure for an automotive electronic water pump. By correspondingly fitting the water pump structural components and the fixed base, the limiting ring and the positioning frame are interlocked, and the straight groove is horizontally fitted to one end of the positioning frame. This structure limits the connection position between the positioning frame and the pump housing, preventing the water pump structural components from rotating and deviating when the fixed base is connected to the water pump structural components, thus improving stability and solving the problem that existing water pumps are circular and may have directional deviation after fixing.

[0016] 2. This utility model provides an assembly structure for an automotive electronic water pump. By using a steering clamp sleeve on the outside of the water pump structural component, the fixed position and direction of the rotating screw in the steering clamp can be adjusted to adapt to the installation space. In this structure, one end of the clamp ring is inserted into the screw kit. The engagement between the rotating screw and the clamp ring allows the rotation of the rotating screw to drive the clamp ring to move, realizing the tightening and disassembly of the water pump structural component and the fixed base. An anti-lifting kit is provided on one side of the clamp ring to insert excess clamp rings and prevent the clamp ring from lifting. This solves the problem that existing water pump assembly structures require screws to be tightened at the top, which is easily limited by the limited installation space for current automotive electronic water pump installations.

Detailed Implementation

[0023] 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.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1 This utility model discloses an assembly structure for an automotive electronic water pump, comprising a water pump component 1, a fixed base 2 attached to the lower end of the water pump component 1, a steering clamp 3 connecting the fixed base 2 and the water pump component 1, two sets of steering clamps 3 arranged side by side, the water pump component 1 including a pump housing 11, a limit ring 111 fixedly provided on one side of the pump housing 11, a straight groove 112 provided on one side of the limit ring 111, the fixed base 2 including a positioning frame 22 attached to the straight groove 112, the steering clamp 3 being inserted through the positioning frame 22, the steering clamp 3 including a clamp ring 31 and a screw kit 32 connected together, one end of the clamp ring 31 being inserted into the screw kit 32, a rotating screw 33 being rotatably provided in the screw kit 32 and engaging with the clamp ring 31, and an anti-tilting kit 311 fixedly provided on one side of the clamp ring 31.

[0026] Specifically, the pump housing 11 is located in the middle of the electronic water pump, and both the front and rear ends are detachable for easy maintenance. The limiting ring 111 is engaged with the positioning frame 22, and the straight groove 112 is horizontally attached to one end of the positioning frame 22. This structure limits the connection position between the positioning frame 22 and the pump housing 11, preventing the water pump structure 1 from rotating and deviating when the fixed base 2 is connected to the water pump structure 1, thus improving stability. The steering clamp 3 is sleeved on the outside of the water pump structure 1, allowing the fixed position and direction of the steering clamp 3 to be adjusted to adapt to the installation space. In this structure, one end of the clamp ring 31 is inserted into the screw kit 32. The engagement between the rotating screw 33 and the clamp ring 31 allows the rotation of the rotating screw 33 to drive the clamp ring 31 to move, realizing the tightening and disassembly between the water pump structure 1 and the fixed base 2. The anti-tilting kit 311 provided on one side of the clamp ring 31 can insert excess clamp ring 31 to prevent the clamp ring 31 from tilting.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combination Figures 2-5 The water pump structural component 1 also includes an end cover 12 provided at one end of the pump housing 11. An external wire 121 is connected to one side of the end cover 12. The pump housing 11 and the end cover 12 are fixed together by screws. The end cover 12 is located at one end, and the external wire 121 is used to connect to an external power source.

[0030] A pump frame 13 is provided on one side of the pump casing 11. An impeller 15 is built into the pump frame 13. The rotation of the impeller 15 drives the water flow between the inlet and outlet of the pump frame 13. A rubber gasket is provided between the pump casing 11 and the pump frame 13 to ensure the sealing of the connection between the pump casing 11 and the pump frame 13.

[0031] A motor 14 is fixedly installed inside the pump casing 11 on one side corresponding to the end cover 12. An impeller 15 is located at the output end of the motor 14. An external wire 121 is connected to the motor 14. The motor 14 drives the impeller 15 to rotate. The two wires inside the external wire 121 supply power to the motor 14.

[0032] Example 2:

[0033] Combination Figures 3-5 The fixed base 2 also includes a base component 21 fixedly disposed at the lower end of the positioning frame 22. The base component 21 is fixed to the car installation position by screws. The fixing space of the water pump structure component 1 provides installation space for the screws of the base component 21. After the fixed base 2 is installed, the clamp ring 31 is inserted into the positioning frame 22, and then the water pump structure component 1 is moved to the straight groove 112 to fit against the positioning frame 22 and aligned. Finally, the clamp ring 31 is inserted into the screw kit 32 to tighten and complete the installation.

[0034] The positioning frame 22 has an arc-shaped sleeve hole 221 for inserting the clamp ring 31. The arc-shaped sleeve hole 221 is arc-shaped to fit the clamp ring 31.

[0035] The anti-tilting kit 311 is fixed on the side where the clamp ring 31 is connected to the screw kit 32. The anti-tilting kit 311 provides a plug-in fixation for the clamp ring 31 after tightening, thereby improving installation stability.

[0036] One side of the clamp ring 31 is provided with a rotating groove 312 aligned with the rotating screw 33. The rotating groove 312 corresponds to the thread of the rotating screw 33, so that when the rotating screw 33 rotates, it can drive the clamp ring 31 to move and adjust the tightness.
