[0037] like Figures 1 to 3 As shown, the present application provides a protective cover for an electronic water pump, comprising:

[0038] The protective cover body 10 is a hexahedral structure with a receiving cavity, including a front side, a rear side, a left side, a right side, an upper side and a lower side, a total of 2 sides are reserved, and the front side of the protective cover body 10 is set to be open, and the electronic water pump is fixed in the receiving cavity;

[0039] A front baffle 20 is detachably mounted on the front side of the protective cover body 10;

[0040] A plurality of strip-shaped heat dissipation holes 30 are provided on the left side, right side and rear side of the protective cover body 10, and heat dissipation convex strips 40 are fixed to the strip-shaped heat dissipation holes 30 on the rear side.

[0041] The protective cover body 10 is fixedly connected to the water pump bracket 60 via the shock absorbing column 50 .

[0042] The protective cover body 10 is provided with a accommodating cavity for accommodating the electronic water pump, which can effectively prevent most mud, sewage, etc. from directly eroding the water pump, play a protective role, reduce the damage rate of water pump components and the abnormal noise of the water pump, ensure the service life of the water pump, and at the same time can reduce the vibration force generated by the electronic water pump motor when it is working, and has a good shock absorption effect. After the electronic water pump is installed, the heat dissipation rib 40 is close to one side of the electronic water pump, and can quickly transfer the heat of the electronic water pump to the protective cover. The heat dissipation rib 40 cooperates with the heat dissipation hole to dissipate the heat generated by the electronic water pump motor when it is working, and has a good heat dissipation effect, which solves the problems of easy damage, increased noise, and reduced life of the electronic water pump of new energy buses and highway coaches.

[0043] Furthermore, the electronic water pump is fixedly connected to the water pump bracket 60 by the shock-absorbing column 50, so that the electronic water pump is stably and firmly installed and is not easy to shift. The water pump and the protective cover share a common fixing point, so the loading and unloading is convenient and reliable, and the stability is high.

[0044] It can be understood that among the six faces of the protective cover body 10 in the present application, the front door is arranged opposite to the rear side face, the left side face is arranged opposite to the right side face, and the upper side face is arranged opposite to the lower side face.

[0045] In some embodiments, at least one limiting ridge 101 is disposed on the left side, right side and lower side connected to the front side of the protective cover body 10 , and the bending direction of any limiting ridge 101 is toward the front side of the protective cover body 10 .

[0046] A limiting ridge 101 bent toward the front side is provided on the left side, right side and lower side of the protective cover body 10. After being bent, the limiting ridge 101 and the upper side of the protective cover body 10 jointly limit the position of the front baffle 20. When installing the front baffle 20, the front baffle 20 can be installed by insertion based on the bent limiting ridge 101 and the side edge of the upper side. At the same time, the bent limiting ridge 101 can also prevent the front baffle 20 from falling off, thereby ensuring the reliability of the protective cover.

[0047] For example, a limiting convex strip 101 is disposed on the left side of the protective cover body 10 , a limiting convex strip 101 is disposed on the right side of the protective cover body 10 , and a limiting convex strip 101 is disposed on the lower side of the protective cover body 10 .

[0048] In some embodiments, a curling ear structure 201 is provided at the middle portion of the upper side of the front baffle 20, which facilitates assembly.

[0049] In some embodiments, a first U-shaped groove 202 for extending the pump body of the electronic water pump is also provided on the front baffle 20. During installation, a portion of the pump body will extend out of the first U-shaped groove 202. The first U-shaped groove 202 is opened on the lower side of the front baffle 20. After the water pump pipeline is assembled, the front baffle 20 is installed through the limiting structure on the front side of the protective cover, which is convenient for disassembly.

[0050] In some embodiments, a second U-shaped groove 102 is disposed on the lower side of the protective cover body 10 , and a plurality of mounting holes 106 are disposed around the second U-shaped groove 102 . The shock absorbing column 50 fixes and connects the water pump, the protective cover and the water pump bracket 60 through the mounting holes 106 .

[0051] It is understandable that the shock absorbing column 50 may be replaced by bolts to reduce the cost.

[0052] In some embodiments, a baffle 103 is provided on the portion of the strip heat dissipation hole 30 located on the outside of the protective cover body 10. The baffle 103 is arranged above the corresponding strip heat dissipation hole 30. The baffle 103 is formed by stamping the strip heat dissipation hole 30, and can prevent most mud, sewage, etc. from entering the interior of the protective cover through the strip heat dissipation hole 30, thereby improving the protective function of the protective cover while ensuring heat dissipation.

[0053] In some embodiments, the wall thickness of the protective cover body 10 is 2.0 mm, and the protective cover body 10 is an integrated stamping structure, and is at least provided with a wire harness through hole 104 and a water outlet pipe through hole 105 .

[0054] The protective cover of the electronic water pump is an integrated stamped protective cover structure, which is stamped using 2.0mm cold-rolled plate. It is low-cost and can reduce the frequency of damage and replacement of water pump components and even power components, thereby achieving cost reduction and efficiency improvement.

[0055] In some embodiments, the wire harness through hole 104 is disposed on the left side surface of the protective cover body 10, and is located on the left side surface of the protective cover body 10 near the rear side surface and the lower side surface;

[0056] The water outlet pipe through hole 105 is arranged on the upper side of the protective cover body 10, and is located at a position of the upper side of the protective cover body 10 close to the front side and the left side. The cross section of the water outlet pipe through hole 105 is U-shaped.

[0057] By arranging the wire harness through hole 104 on the left side surface and the water outlet pipe passing through the hole 105 on the upper side surface, it is more in line with the design characteristics of the electronic water pump.

[0058] In some embodiments, the wiring harness through hole 104, the water outlet pipe through hole 105, and the surface where the front baffle 20 contacts the protective cover are all provided with rubber strips or sponge strips for protecting the pipelines and reducing vibration and noise.

[0059] In some embodiments, sound-absorbing cotton is disposed on the inner side of each surface of the protective cover body 10, which can further enhance the noise reduction effect of the protective cover.

[0060] Installation process of the protective cover of the electronic water pump of this application

[0061] First, align the multiple φ7 mounting holes 106 on the lower side of the protective cover with the mounting holes 106 of the water pump bracket 60, and then install the water pump on the mounting holes 106 at the bottom of the protective cover. It can be connected to the through-hole shock-absorbing column 50 or connected by 4-M6*25 hexagonal flange bolts and nuts. The connection is firm and reliable.

[0062] Paste a sponge strip or a rubber strip at the position of the wire harness through hole 104 to protect the pipeline, and then install the corresponding pipeline of the water pump;

[0063] A sponge strip or a rubber strip is pasted on the front baffle 20 to reduce vibration and noise. The front baffle 20 is installed from top to bottom and is limited by the limiting convex strip 101 on the protective cover. The installation of the protective cover structure is completed.
