Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to an electronic water pump and a vehicle. Background Art

[0002] In electric vehicles, the electronic water pump is one of the core components of thermal management. In order to improve user experience, higher requirements are currently placed on the vibration and noise effects of the vehicle. However, the electronic water pump usually needs to be installed on the frame. When the vehicle is running, both the frame and the water pump will vibrate, which will not only generate loud noise and reduce the user's driving and riding experience, but the water pump is also easily damaged by the vibration of the frame. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present application provides an electronic water pump.

[0005] A second aspect of the present application provides a vehicle.

[0006] In view of this, the first aspect of the present application provides an electronic water pump, which includes: a water pump body, a shock-absorbing washer and a bracket assembly. The shock-absorbing washer is sleeved on the water pump body, and along the circumference of the shock-absorbing washer, a first connecting portion and a second connecting portion are provided on the shock-absorbing washer, and the first connecting portion is detachably connected to the second connecting portion so that the shock-absorbing washer can be detachably sleeved on the water pump body, and the outer ring of the shock-absorbing washer is provided with a first groove, and the first groove extends along the axial direction of the shock-absorbing washer, and the first groove is used to provide an escape space for the shock-absorbing washer during installation and removal. The bracket assembly is sleeved on the shock-absorbing washer, and the bracket assembly is used to connect to the frame of the vehicle, and the bracket assembly includes a first bracket and a second bracket, and the first bracket is detachably connected to the second bracket so that the bracket assembly can be detachably sleeved on the shock-absorbing washer.

[0007] In the technical solution, the electronic water pump includes a water pump body, a shock-absorbing washer and a bracket assembly. The shock-absorbing washer can be an annular structure, and the shock-absorbing washer is sleeved on the water pump body. The shock-absorbing washer is made of elastic material, and the shock-absorbing washer is used to absorb the vibration generated by the water pump body. Exemplarily, the shock-absorbing washer can be made of rubber material.

[0008] A first connection portion and a second connection portion are provided on the shock-absorbing washer along the circumference of the shock-absorbing washer. Specifically, a fracture is provided along the circumference of the shock-absorbing washer, and the first connection portion and the second connection portion are provided at both ends of the fracture. The first connection portion is detachably connected to the second connection portion. When the first connection portion is connected to the second connection portion, at least a portion of the shock-absorbing washer can be closed to form a ring, so that the shock-absorbing washer can be detachably sleeved on the water pump body, which is convenient for the maintenance and replacement of the shock-absorbing washer in subsequent use, thereby improving the convenience of the maintenance and replacement of the shock-absorbing washer.

[0009] The bracket assembly is sleeved on the shock-absorbing washer, and the bracket assembly is used to connect to the vehicle frame. Since the shock-absorbing washer absorbs the vibration generated by the water pump body, the vibration of the water pump body relative to the bracket assembly is reduced, thereby reducing the vibration amplitude of the water pump body relative to the frame.

[0010] The bracket assembly includes a first bracket and a second bracket, the first bracket is detachably connected to the second bracket, and when the first bracket and the second bracket are in a connected state, at least a portion of the bracket assembly can be closed to form a ring, so that the bracket assembly can be detachably mounted on the shock-absorbing gasket, which is convenient for maintenance and replacement of the bracket assembly in subsequent use, thereby improving the convenience of maintenance and replacement of the bracket assembly.

[0011] In this way, the shock-absorbing washer is sleeved on the water pump body, and the bracket assembly is sleeved on the shock-absorbing washer, so that the structure is compact, the space occupied by the electronic water pump is reduced, and the vibration between the water pump body and the frame is reduced, the vibration resistance of the water pump body and the bracket assembly is improved, the vibration of the electronic water pump when the car is running is reduced, and the shock-absorbing effect of the electronic water pump is optimized, thereby reducing the vibration amplitude of the frame and the noise generated by the vehicle. The buffer structure formed by the shock-absorbing washer can prevent the water pump body from being damaged by the vibration of the frame, so as to extend the service life of the electronic water pump. In addition, the shock-absorbing washer is detachably sleeved on the water pump body, and the bracket assembly is detachably sleeved on the shock-absorbing washer, which improves the convenience of the bracket assembly and the shock-absorbing washer during the maintenance and replacement process, improves the efficiency of the maintenance and replacement of the bracket assembly, and improves the flexibility and adaptability of the installation of the electronic water pump.

[0012] The outer ring of the shock-absorbing washer is provided with a first groove, and the first groove extends along the axial direction of the shock-absorbing washer. It can be understood that the shock-absorbing washer is squeezed during installation and disassembly, causing the outer ring of the shock-absorbing washer to deform. The first groove is used to provide an escape space for the shock-absorbing washer during installation and disassembly, thereby avoiding damage to the shock-absorbing washer due to squeezing during installation and disassembly, and reducing the deformation resistance encountered by the shock-absorbing washer during installation and disassembly, thereby improving the convenience of installation and disassembly of the shock-absorbing washer.

[0013] In addition, the electronic water pump in the above technical solution provided by this application may also have the following additional technical features:

[0014] In some technical solutions provided in the present application, optionally, a first mounting portion and a second mounting portion are provided on the water pump body, and the first mounting portion and the second mounting portion are spaced apart along the axial direction of the water pump body.

[0016] One axial end of the shock-absorbing washer abuts against the first mounting portion, and the other axial end of the shock-absorbing washer abuts against the second mounting portion, so that the first mounting portion and the second mounting portion limit the shock-absorbing washer to prevent the shock-absorbing washer from moving along the axial direction of the water pump body. In addition, the contact area between the shock-absorbing washer and the water pump body is increased, thereby improving the shock-absorbing effect of the shock-absorbing washer on the water pump body.

[0017] In some technical solutions provided in the present application, optionally, a reinforcing rib is provided on the water pump body, and a second groove is provided on the inner ring of the shock-absorbing washer. When the shock-absorbing washer is connected to the water pump body, the reinforcing rib extends into the second groove.

In the direction away from the axis, that is, in the direction toward the outer periphery of the shock-absorbing washer, the distance between the groove walls of the first groove increases, so that the width of the first groove increases. Exemplarily, the cross-section of the first groove can be triangular, so that the avoidance space that can be provided by the first groove gradually increases, thereby improving the avoidance effect of the first groove on deformation, thereby improving the convenience of installation and removal of the shock-absorbing washer.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0070] Refer to the following Figures 1 to 12 An electronic water pump 10 and a vehicle according to some embodiments of the present application are described.

[0071] The first aspect of the present application provides an electronic water pump 10, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the electronic water pump 10 provided in the present application includes: a water pump body 100, a shock absorbing washer 200 and a bracket assembly 300. The shock absorbing washer 200 is sleeved on the water pump body 100, and the shock absorbing washer 200 is provided along the circumference ( Figure 1 The arrow at c in the middle points to the circumferential direction of the shock-absorbing washer 200). The shock-absorbing washer 200 is provided with a first connecting portion 210 and a second connecting portion 220. The first connecting portion 210 is detachably connected to the second connecting portion 220 so that the shock-absorbing washer 200 can be detachably mounted on the water pump body 100. The outer ring of the shock-absorbing washer 200 is provided with a first groove 260. The first groove 260 extends along the axial direction of the shock-absorbing washer 200. The first groove 260 is used to provide a clearance space for the shock-absorbing washer 200 during installation and removal. The bracket assembly 300 is mounted on the shock-absorbing washer 200. The bracket assembly 300 is used to connect to the vehicle frame. The bracket assembly 300 includes a first bracket 310 and a second bracket 320. The first bracket 310 is detachably connected to the second bracket 320 so that the bracket assembly 300 can be detachably mounted on the shock-absorbing washer 200.

[0072] In this embodiment, the electronic water pump 10 includes a water pump body 100, a shock absorbing washer 200 and a bracket assembly 300. The shock absorbing washer 200 may be an annular structure, and the shock absorbing washer 200 is sleeved on the water pump body 100. The shock absorbing washer 200 is made of elastic material, and the shock absorbing washer 200 is used to absorb the vibration generated by the water pump body 100. Exemplarily, the shock absorbing washer 200 may be made of rubber material.

[0073] A first connection portion 210 and a second connection portion 220 are provided on the shock absorbing washer 200 along the circumference of the shock absorbing washer 200. Specifically, a fracture is provided along the circumference of the shock absorbing washer 200, and the first connection portion 210 and the second connection portion 220 are provided at both ends of the fracture.

[0076] In this way, the shock-absorbing washer 200 is sleeved on the water pump body 100, and the bracket assembly 300 is sleeved on the shock-absorbing washer 200, so that the structure is compact, the space occupied by the electronic water pump 10 is reduced, and the vibration between the water pump body 100 and the frame is reduced, the vibration resistance of the water pump body 100 and the bracket assembly 300 is improved, the vibration of the electronic water pump 10 when the car is running is reduced, and the shock-absorbing effect of the electronic water pump 10 is optimized, thereby reducing the vibration amplitude of the frame and reducing the noise generated by the vehicle, which is conducive to improving the user's riding and driving experience. The buffer structure formed by the shock-absorbing washer 200 can prevent the water pump body 100 from being damaged by the vibration of the frame, so as to extend the service life of the electronic water pump 10. In addition, the shock-absorbing gasket 200 can be detachably mounted on the water pump body 100, and the bracket assembly 300 can be detachably mounted on the shock-absorbing gasket 200, which improves the convenience of the bracket assembly 300 and the shock-absorbing gasket 200 during maintenance and replacement, improves the efficiency of maintenance and replacement of the bracket assembly 300, and improves the flexibility and adaptability of the installation of the electronic water pump 10.

[0077] The outer ring of the shock-absorbing washer 200 is provided with a first groove 260, and the first groove 260 extends along the axial direction of the shock-absorbing washer 200. It can be understood that the shock-absorbing washer 200 is squeezed during installation and disassembly, causing the outer ring of the shock-absorbing washer 200 to deform. The first groove 260 is used to provide an escape space for the shock-absorbing washer 200 during installation and disassembly, thereby avoiding damage to the shock-absorbing washer 200 due to squeezing during installation and disassembly, and reducing the deformation resistance of the shock-absorbing washer 200 during installation and disassembly, thereby improving the convenience of installation and disassembly of the shock-absorbing washer 200.

[0078] Specifically, the first groove 260 is disposed at a position of the shock absorbing washer 200 away from the first connecting portion 210 and the second connecting portion 220 in the circumferential direction, that is, the first groove 260 is disposed at a position opposite to the first connecting portion 210 and the second connecting portion 220 .

The installation space can be an annular groove, and the shock-absorbing washer 200 is located between the first mounting portion 110 and the second mounting portion 120, so that the shock-absorbing washer 200 is accommodated in the above-mentioned installation space.

[0082] One axial end of the shock-absorbing washer 200 abuts against the first mounting portion 110, and the other axial end of the shock-absorbing washer 200 abuts against the second mounting portion 120, so that the first mounting portion 110 and the second mounting portion 120 limit the shock-absorbing washer 200 to prevent the shock-absorbing washer 200 from moving along the axial direction of the water pump body 100. In addition, the contact area between the shock-absorbing washer 200 and the water pump body 100 is increased, and the shock-absorbing effect of the shock-absorbing washer 200 on the water pump body 100 is improved.

When the shock-absorbing washer 200 is connected to the water pump body 100 , the reinforcing rib 130 extends into the second groove 230 .

[0084] In this embodiment, the water pump body 100 is provided with a reinforcing rib 130, and the reinforcing rib 130 is used to improve the structural strength of the water pump body 100. Specifically, the reinforcing rib 130 is provided on the outer peripheral surface of the mounting column, and the reinforcing rib 130 extends along the axial direction of the water pump body 100. The inner ring of the shock-absorbing washer 200 is provided with a second groove 230. When the shock-absorbing washer 200 is connected to the water pump body 100, the reinforcing rib 130 extends into the second groove 230, and the reinforcing rib 130 and the second groove 230 are clearance-matched, so that the reinforcing rib 130 is accommodated in the second groove 230, so as to prevent the shock-absorbing washer 200 from rotating, and to prevent the reinforcing rib 130 from affecting the installation of the shock-absorbing washer 200 or extending out of the shock-absorbing washer 200, thereby increasing the contact area between the shock-absorbing washer 200 and the water pump body 100, and improving the shock-absorbing effect of the shock-absorbing washer 200 on the water pump body 100.

[0085] Specifically, the shape of the second grooves 230 matches the shape of the reinforcing ribs 130 , and the number of the second grooves 230 is greater than or equal to the number of the reinforcing ribs 130 .

[0086] In some embodiments provided in this application, Figure 6 and Fig. 9 As shown, optionally, the water pump body 100 is provided with a first positioning portion 140 , and the outer ring of the shock-absorbing washer 200 is provided with a second positioning portion 240 , and when the first positioning portion 140 and the second positioning portion 240 are aligned, the reinforcing rib 130 extends into the second groove 230 .

[0087] In this embodiment, since the outer periphery of the water pump body 100 is provided with a reinforcing rib 130, when the second groove 230 is located at a position corresponding to the reinforcing rib 130, the shock-absorbing washer 200 can be smoothly sleeved on the water pump body 100. By providing the first positioning portion 140 on the water pump body 100 and the second positioning portion 240 on the outer ring of the shock-absorbing washer 200, when the first positioning portion 140 and the second positioning portion 240 are aligned, the reinforcing rib 130 extends into the second groove 230, that is, through the first positioning portion 140 and the second positioning portion 240, the position of the first groove corresponding to the reinforcing rib 130 can be quickly found, and then the correct installation position of the shock-absorbing washer 200 can be found, which improves the convenience of the shock-absorbing washer 200 during the installation process and improves the installation, maintenance and replacement efficiency of the shock-absorbing washer 200.

[0088] For example, the first positioning portion 140 and the second positioning portion 240 may be positioning grooves, positioning protrusions, or marks drawn on the outer circumference of the water pump body 100 and the shock-absorbing washer 200 .

[0089] In some embodiments provided in this application, Figure 4 and Figure 5 As shown, optionally, the shock-absorbing washer 200 is provided with a plurality of through holes 250 , the through holes 250 penetrate the shock-absorbing washer 200 along the axial direction of the shock-absorbing washer 200 , and the plurality of through holes 250 are distributed at intervals along the circumference of the shock-absorbing washer 200 .

[0090] In this embodiment, the shock-absorbing washer 200 is provided with a plurality of through holes 250, which penetrate the shock-absorbing washer 200 along the axial direction of the shock-absorbing washer 200. The through holes 250 can increase the deformation of the shock-absorbing washer 200, increase the vibration amount that the shock-absorbing washer 200 can absorb, lengthen the vibration transmission path, reduce vibration energy, and thus improve the shock-absorbing effect of the shock-absorbing washer 200. In addition, the material usage of the shock-absorbing washer 200 is reduced, and the weight and material cost of the shock-absorbing washer 200 are reduced, thereby reducing the weight and material cost of the electronic water pump 10.

[0091] Specifically, there are multiple through holes 250 , and the multiple through holes 250 are distributed at intervals along the circumference of the shock-absorbing washer 200 . The multiple through holes 250 can be evenly distributed in the circumference of the shock-absorbing washer 200 .

[0092] In some embodiments provided in this application, Figure 5 As shown, optionally, the shock absorbing washer 200 has an axis, and the width of the first groove 260 increases in a direction away from the axis.

[0093] In this embodiment, the shock absorbing washer 200 has an axis, such as Figure 5As shown, B is the axis of the shock-absorbing washer 200. It can be understood that the shock-absorbing washer 200 is squeezed during installation and removal, causing the outer ring of the shock-absorbing washer 200 to deform, and the deformation of the shock-absorbing washer 200 gradually increases in the direction away from the axis, that is, in the direction toward the outer periphery of the shock-absorbing washer 200. In the direction away from the axis, that is, in the direction toward the outer periphery of the shock-absorbing washer 200, the distance between the groove walls of the first groove 260 increases, so that the width of the first groove 260 increases. For example, the cross-section of the first groove 260 can be triangular, so that the avoidance space that can be provided by the first groove 260 gradually increases, thereby improving the avoidance effect of the first groove 260 on deformation, thereby improving the convenience of installation and removal of the shock-absorbing washer 200.

[0094] In some embodiments provided in this application, Figure 4 and Figure 5 As shown, optionally, a mounting groove 270 is provided on the shock-absorbing washer 200 , and the mounting groove 270 is distributed along the circumference of the shock-absorbing washer 200 , and the bracket assembly 300 is located in the mounting groove 270 so that the axial ends of the bracket assembly 300 abut against the shock-absorbing washer 200 .

The mounting groove 270 may be an annular groove, and the bracket assembly 300 is located in the mounting groove 270, so that the axial ends of the bracket assembly 300 abut against the shock-absorbing washer 200, so that the mounting groove 270 limits the bracket assembly 300, and prevents the bracket assembly 300 from moving along the axial direction of the shock-absorbing washer 200. In addition, the contact area between the bracket assembly 300 and the shock-absorbing washer 200 is increased, and the shock-absorbing effect of the shock-absorbing washer 200 on the bracket assembly 300 is improved.

[0096] Exemplarily, both ends of the shock absorbing washer 200 may be provided with flange structures to form the mounting groove 270. Alternatively, along the axial direction of the shock absorbing washer 200, the thickness between the two ends of the shock absorbing washer 200 is reduced, so that the thickness in the middle of the shock absorbing washer 200 is smaller than the thickness at the two ends to form the mounting groove 270.

[0097] In some embodiments provided in this application, Figure 4 and Figure 5 As shown, optionally, one of the first connection portion 210 and the second connection portion 220 includes a protrusion 211, and the other includes a groove portion 221, the protrusion 211 is inserted into the groove portion 221, and the protrusion 211 can be extended along the thickness direction ( Figure 4 The arrow d in the middle points to the thickness direction of the shock absorbing washer 200 , and the shock absorbing washer 200 slides relative to the groove portion 221 .

[0098] In this embodiment, one of the first connection part 210 and the second connection part 220 includes a protrusion 211, and the other includes a groove 221.

Or the first connection part 210 includes the groove 221, and the second connection part 220 includes the protrusion 211. The protrusion 211 and the groove 221 can be clearance fit.

[0099] Specifically, the groove portion 221 may be a dovetail groove, and the protrusion 211 matches the shape of the groove portion 221. There may be a plurality of groove portions 221, and the number of the protrusions 211 is the same as that of the groove portions 221.

[0100] The protrusion 211 is plugged into the groove 221, and the connection method is simple and stable, which improves the stability and convenience of the connection between the first connection part 210 and the second connection part 220. The protrusion 211 can slide relative to the groove 221 along the thickness direction of the shock-absorbing washer 200, which improves the flexibility and adaptability of the connection between the first connection part 210 and the second connection part 220.

The second step is to put the first bracket 310 on the outer ring of the vibration-damping washer, and the positioning groove 280 on the vibration-damping washer and the positioning portion 330 on the first bracket 310 play a positioning role. The third step is to put the rectangular plug hole 321 of the second bracket 320 on the plug-in portion 312 of the first bracket 310, and the second bracket 320 is put on the outer ring of the vibration-damping washer. The fourth step is to connect the through hole of the second bracket 320 and the convex welding nut 316 on the first bracket 310 through the hexagonal flange bolt (i.e., the locking member 400).

[0131] In the first step, the vibration damping washer is opened first, and the second positioning portion 240 on the vibration damping washer is aligned with the first positioning portion 140 on the water pump body 100. The second groove 230 on the inner side of the vibration damping is designed to correspond to the reinforcing rib 130 on the outer wall of the water pump body 100, and the second groove 230 and the reinforcing rib 130 are clearance fit (avoiding air), and the reinforcing rib 130 plays a role in preventing the vibration damping washer from rotating. Then the protrusion 211 and the groove 221 at both ends of the vibration damping washer fracture are matched to achieve the closure of the vibration damping washer, and the protrusion 211 and the groove 221 are clearance fit. The upper end matching surface of the vibration damping washer cooperates with the lower end surface of the first mounting portion 110 to form a support, and the lower end matching surface of the vibration damping washer cooperates with the upper end surface of the second mounting portion 120 to form a support, and the inner ring of the vibration damping washer and the outer ring of the water pump body 100 are small clearance and transition fit.

[0132] In the second step, the positioning portion 330 of the first bracket 310 is first matched with the positioning groove 280 of the vibration damping washer, and the positioning portion 330 and the positioning groove 280 are clearance-matched. At the same time, the inner ring of the first bracket 310 is sleeved in the outer ring annular mounting groove 270 of the vibration damping washer. The inner ring diameter of the first bracket 310 is smaller than the diameter of the bottom surface of the outer ring annular mounting groove 270 of the vibration damping washer, that is, the first bracket 310 and the vibration damping washer are interference fit, and the through hole 250 opened in the middle of the vibration damping washer is also more conducive to avoiding the bracket assembly 300 and the vibration damping washer from being squeezed during interference assembly.

[0133] When performing the third step, first, the rectangular plug hole 321 of the second bracket 320 is inserted into the plug portion 312 of the first bracket 310, and at the same time, the inner ring of the second bracket 320 is inserted into the outer ring annular mounting groove 270 of the vibration damping washer. The inner ring diameter of the second bracket 320 is smaller than the diameter of the bottom surface of the outer ring annular mounting groove 270 of the vibration damping washer, that is, the bracket assembly 300 and the vibration damping washer are interference fit.

[0134] During the fourth step, the hexagonal flange bolt passes through the through hole of the second bracket 320 and is fastened to the convex welding nut 316 on the first bracket 310. After the bolt is tightened, the first bracket 310 and the second bracket 320 hold the vibration-damping washer tightly, and the end face of the plug-in portion 312 of the first bracket 310 is flush with the end face of the rectangular plug-in hole 321 of the second bracket 320.

[0135] The present application is a rubber vibration-damping bracket assembly 300 for an electronic water pump 10 of a pure electric vehicle. An open vibration-damping washer is sleeved on the water pump body 100. The bracket assembly 300 is fastened by bolts and then tightly holds the vibration-damping washer. The sub-connecting portion 314 is fastened to the vehicle frame by screws, thereby realizing a fixed connection among the water pump body 100, the vibration-damping washer, the bracket assembly 300 and the vehicle frame. In combination with a vibration-damping through hole 250 opened in the middle of the vibration-damping washer, the vibration transmission path can be effectively lengthened, the vibration energy can be reduced, and the vibration of the electronic water pump 10 when the vehicle is running can be reduced. At the same time, the multiple sub-connecting portions 314 of the first bracket 310 can also realize the installation of the electronic water pump 10 at different angles, and the first bracket 310 can be changed and share the same second bracket 320, thereby improving the installation adaptability of the electronic water pump 10 and reducing the production and replacement costs of the bracket assembly 300.

[0136] The split design of the open vibration-damping washer and the bracket assembly 300 facilitates installation and disassembly, and the vibration-damping washer used can have a lower hardness and a better vibration-damping effect.
