Description

Technical Field

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

[0002] An automotive electronic water pump is a cooling system component driven by an electric motor and precisely regulated by an electronic control unit (ECU). It is used to replace the traditional mechanical water pump driven by an engine belt. Its main function is to control the circulation of coolant between components such as the engine and radiator, thereby achieving intelligent management of engine temperature.

[0003] In automotive electronic water pumps, a core component is the impeller. Currently, impellers are installed using bolts. This bolt installation method requires specialized tools for fixing, and the complexity of using these tools makes the entire fixing process relatively slow, consuming a lot of time and effort. Furthermore, when the impeller needs maintenance, the bolt installation makes it impossible to quickly disassemble it. This inconvenience greatly affects the user's operating efficiency and experience, making daily maintenance and repair work cumbersome and time-consuming, causing many inconveniences for users.

[0004] Therefore, it is necessary to provide an impeller for an automotive electronic water pump to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an impeller for an automotive electronic water pump, which solves the problems of current impellers using bolt installation, which requires special tools for fixing, is relatively slow, and cannot be quickly opened for maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an impeller for an automotive electronic water pump, comprising an automotive electronic water pump, a top cover fixedly mounted on the top of the automotive electronic water pump, a transmission rod rotatably connected inside the automotive electronic water pump, an impeller slidably connected to the surface of the transmission rod, fixing grooves on both sides of the transmission rod, a clamping component inside the fixing groove, and a connecting component inside the transmission rod;

[0007] The clamping assembly is used to fix the impeller;

[0008] The connecting component is used to drive the clamping component.

[0009] Preferably, the clamping assembly includes a clamping block, which is slidably connected inside the fixing groove. A threaded sleeve is fixedly connected to the inner side of the clamping block, and a screw rod is threadedly connected to the inner side of the threaded sleeve. The inner side of the screw rod extends through to the inner side of the transmission rod and is rotatably connected to the inside of the transmission rod.

[0010] Preferably, the connecting assembly includes a first helical gear, and there are two first helical gears. The first helical gear is fixedly connected to the inner end of the screw. A second helical gear is provided inside the transmission rod. The second helical gear meshes with the first helical gear. A torsion bar is fixedly connected to the top of the second helical gear.

[0011] Preferably, the top and bottom of the card block are fixedly connected to sliders, and the top and bottom of the inner wall of the fixing groove are provided with sliding grooves that are slidably connected to the sliders.

[0012] Preferably, a rotating block is fixedly connected to the top of the torsion bar, and the rotating block is located at the top of the transmission bar.

[0013] Preferably, a metal ring is fixedly connected inside the transmission rod, and the bottom of the torsion rod extends through to the bottom of the second helical gear and is rotatably connected to the top of the metal ring.

[0014] Preferably, a limiting bracket is fixedly connected to the top of the metal ring, and the limiting bracket is rotatably connected to the inner side of the second helical gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows for quick and efficient installation of the impeller. When the impeller needs to be fixed, the user places it on the transmission rod, then twists the rotating block. The rotating block drives the torsion rod to rotate, which in turn drives the second helical gear to rotate. The second helical gear then drives the first helical gear to rotate, which in turn drives the screw to rotate. The rotation of the screw causes the screw sleeve to move, which in turn causes the locking block to extend outward. This outward extension of the locking block limits the top of the impeller, allowing for quick and efficient installation. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 An impeller for an automotive electronic water pump includes an automotive electronic water pump 1. A top cover 2 is fixedly installed on the top of the automotive electronic water pump 1. A transmission rod 3 is rotatably connected inside the automotive electronic water pump 1. An impeller 4 is slidably connected to the surface of the transmission rod 3. Fixing grooves 5 are provided on both sides of the transmission rod 3. A clamping component 6 is provided inside the fixing groove 5. A connecting component 7 is provided inside the transmission rod 3.

[0024] The clamping assembly 6 is used to fix the impeller 4;

[0025] The connecting component 7 is used to drive the clamping component 6.

[0026] Please see Figure 4 The clamping assembly 6 includes a clamping block 61, which is slidably connected inside the fixing groove 5. A threaded sleeve 62 is fixedly connected to the inner side of the clamping block 61, and a screw rod 63 is threadedly connected to the inner side of the threaded sleeve 62. The inner side of the screw rod 63 extends through to the inner side of the transmission rod 3 and is rotatably connected to the inside of the transmission rod 3.

[0027] Furthermore, by setting the clamping component 6, we can precisely limit the top of the impeller 4. This design greatly improves the stability of the impeller 4 and makes the fixing process of the impeller 4 simpler and more reliable. The function of the clamping component 6 is to ensure that the impeller 4 will not be displaced when rotating at high speed, thereby ensuring the normal operation of the entire equipment.

[0028] Please see Figure 4The connecting component 7 includes a first helical gear 71, and there are two first helical gears 71. The first helical gear 71 is fixedly connected to the inner end of the screw 63. The transmission rod 3 is provided with a second helical gear 72, which meshes with the first helical gear 71. A torsion rod 73 is fixedly connected to the top of the second helical gear 72.

[0029] Furthermore, the introduction of connecting component 7 makes the transmission process of the card block 61 smoother, and the card block 61 can move outward efficiently. This design not only improves the movement efficiency, but also makes the card block 61 slide more smoothly during use, reducing friction and resistance and extending the service life of the equipment.

[0030] Please see Figure 4 The top and bottom of the card block 61 are fixedly connected to the slider 8, and the top and bottom of the inner wall of the fixing groove 5 are provided with sliding grooves 9 that are slidably connected to the slider 8.

[0031] Furthermore, the design of slider 8 also plays a crucial role. It can effectively limit the top and bottom of block 61, ensuring that block 61 remains stable during sliding and does not shift or wobble, thus guaranteeing the smoothness and reliability of the entire sliding process.

[0032] Please see Figure 3 A rotating block 10 is fixedly connected to the top of the torsion bar 73, and the rotating block 10 is located at the top of the transmission bar 3.

[0033] Furthermore, the design of the rotating block 10 makes the transmission of the torsion bar 73 more flexible. The torsion bar 73 can easily drive the second helical gear 72 to rotate. This design greatly improves the ease of operation of the equipment, making it easier for users to operate.

[0034] Please see Figure 4 A metal ring 11 is fixedly connected inside the transmission rod 3, and the bottom of the torsion rod 73 passes through to the bottom of the second helical gear 72 and is rotatably connected to the top of the metal ring 11.

[0035] Furthermore, the metal ring 11 provides solid support for the bottom of the torsion bar 73, ensuring the stability of the torsion bar 73 and preventing it from wobbling during use, thereby improving the safety of the equipment.

[0036] Please see Figure 4 The top of the metal ring 11 is fixedly connected to a limiting bracket 12, and the limiting bracket 12 is rotatably connected to the inner side of the second helical gear 72.

[0037] Furthermore, the design of the limiting bracket 12 provides stable support for the inner side of the first helical gear 71, ensuring the stability of the first helical gear 71 and avoiding the problem of shaking during use, thereby improving the overall performance and reliability of the equipment.

[0038] The specific implementation process of this utility model is as follows: When it is necessary to fix the impeller 4, the user first needs to accurately put the impeller 4 on the transmission rod 3 to ensure that the fit between the impeller 4 and the transmission rod 3 is tight and correct. Next, the user manually rotates the rotating block 10. After the rotating block 10 is subjected to external force, it will drive the torsion rod 73 connected to it to rotate synchronously. The rotational motion of the torsion rod 73 is further transmitted to the second helical gear 72, so that the second helical gear 72 also starts to rotate. The rotation of the second helical gear 72 is not isolated. It will drive the first helical gear 71 that it is engaged with to rotate synchronously through the meshing action between gears. During the rotation of the first helical gear 71, it will drive the screw 63 connected to it to rotate. The rotational motion of the screw 63 is further transmitted to the screw sleeve 62, causing the screw sleeve 62 to move linearly under the action of the screw thread 63. The movement of the screw sleeve 62 is not a simple translation; it drives the connected locking block 61 to extend outward. The outward extension of the locking block 61 can effectively limit and fix the top of the impeller 4, ensuring that the impeller 4 is firmly and reliably positioned on the transmission rod 3. Through this series of precise and coordinated actions, the user can quickly and efficiently complete the installation of the impeller 4, thereby achieving a high-efficiency and rapid installation effect, significantly improving work efficiency and installation quality.
