As shown in fig. 1, an embodiment of the present invention provides a pipe joint 10 for a drive system for connecting a cooling passage of a motor controller 20 and a cooling passage of a decelerator assembly 30.
Referring to fig. 2 to 4, the pipe joint further includes a connecting pipe 11 and an elastic joint 12. The connecting pipe 11 includes a first end 118 and a second end 119 that are mutually communicated, the first end 118 is used for being connected with the cooling channel of the motor controller 20, the elastic connector 12 is sleeved on the outer side wall of the second end 119 of the connecting pipe 11, and the second end 119 of the connecting pipe 11 is used for being inserted into the cooling channel of the speed reducer assembly, and the elastic connector 12 is in interference fit with the cooling channel of the speed reducer assembly, so that the connecting pipe 11 is connected with the cooling channel of the speed reducer assembly 30.
By adopting the pipeline joint, the connecting pipe 11 can be connected with the cooling channel of the motor controller 20, after the connection, the elastic connector 12 is inserted into the cooling channel of the speed reducer assembly 30, so that the connection between the second end 119 of the connecting pipe 11 and the cooling channel of the speed reducer assembly 30 can be realized, and the elastic connector 12 at the second end 119 of the connecting pipe 11 is in interference fit with the cooling channel of the speed reducer assembly 30, so that the connection tightness can be ensured, and the failure and water seepage can be avoided. Thus, the cooling passage of the motor controller 20 and the cooling passage of the reducer assembly 30 can be quickly connected, the assembly time is shortened, and the assembly efficiency is improved.
It should be noted that a sealing structure, typically a rubber structure, is provided at the cooling channel of the motor controller 20 to ensure the sealing property of the connection between the connection pipe 11 and the cooling channel of the motor controller 20.
Meanwhile, the connection between the cooling channel of the existing motor controller 20 and the cooling channel of the reducer assembly 30 is communicated through a rubber water pipe, in order to ensure the stability of the rubber water pipe, the rubber water pipe is usually embedded in a metal groove, and the rubber water pipe is long, so that the resistance of the cooling liquid in the rubber water pipe is large, the flow speed of the cooling liquid is reduced, and the cooling effect of the cooling liquid is weak.
In some embodiments, the connecting tube 11 includes a first connecting portion 111, an intermediate portion 112 and a second connecting portion 113 connected in sequence along an axial direction thereof, the first connecting portion 111 is used for being connected with the cooling channel of the motor controller 20, the elastic connector 12 is sleeved on the second connecting portion 113, and the elastic connector 12 is inserted into the cooling channel of the reducer assembly 30 after being sleeved on the second connecting portion 113 and is in interference fit therewith, so that the second connecting portion 113 is connected with the cooling channel of the reducer assembly 30.
Further, the outer diameter of the second connecting portion 113 is smaller than the outer diameter of the middle portion 112, and the elastic connector 12 is sleeved on the second connecting portion 113 and abuts against the middle portion 112. Therefore, the elastic connector 12 can be limited, and the elastic connector 12 is prevented from moving.
It can be understood that, the elastic connection head 12 is in interference fit with the cooling channel of the speed reducer assembly 30, the elastic connection head 12 is subjected to a large resistance during the insertion process, the resistance may cause the elastic connection head 12 to have a tendency to move toward the middle portion 112 relative to the second connection portion 113, and at this time, the middle portion 112 limits the movement of the elastic connection head 12 due to the abutment of the elastic connection head 12 with the middle portion 112, so that the elastic connection head 12 is smoothly inserted into the cooling channel of the speed reducer assembly 30.
In practical applications, the connecting pipe 11 is a metal pipe. It can be understood that the first connecting portion 111, the middle portion 112 and the second connecting portion 113 are all round tubes, and are sequentially connected along the axial direction of the connecting tube 11, that is, the connecting tube 11 is a metal straight round tube, by using the connecting tube 11, the cooling channel of the motor controller 20 and the cooling channel of the speed reducer assembly 30 can be directly connected, the connection distance between the cooling channel of the motor controller 20 and the cooling channel of the speed reducer assembly 30 is effectively shortened, so that the resistance to the cooling liquid is reduced, the flow rate of the cooling liquid is increased, and the cooling effect of the cooling liquid is further improved.
In addition, after the connection distance between the cooling channel of the motor controller 20 and the cooling channel of the reducer assembly 30 is shortened, the structure is more compact, and the space utilization rate is improved.
In some embodiments, the length of the elastic connector 12 in the axial direction of the connection pipe 11 is the same as the length of the second connection portion 113 in the axial direction of the connection pipe 11, so that the connection pipe 11 is more beautiful as a whole.
It should be noted that, when the length of the elastic connector 12 is short, the metal connecting pipe 11 protrudes out of the elastic connector 12, and in order to protect the metal pipe, flexible protection structures need to be arranged at both ends of the metal pipe; when the length of the elastic connection head 12 is too long, the material cost is increased.
In some embodiments, the first end 118 of the connecting tube 11 is threaded with the cooling channel of the motor controller 20 to further improve the sealing and stability of the connection. Meanwhile, during assembly, the connecting pipe 11 may be first screwed to the cooling channel controlled by the motor, and then the elastic connector 12 sleeved on the connecting pipe 11 may be inserted into the cooling channel of the reducer assembly 30.
Further, an outer side wall of the first end 118 of the connection pipe 11 is externally threaded to realize a threaded connection between the connection pipe 11 and the cooling channel of the motor controller 20.
In other embodiments, the first end 118 of the connection tube 11 may be provided with an internal thread, and the cooling channel corresponding to the motor controller 20 may be provided with an external thread matching with the internal thread. Of course, the connection pipe 11 is preferably externally threaded.
In practical applications, the outer diameter of the first connecting portion 111 is the same as the outer diameter of the intermediate portion 112, and the outer side wall of the first connecting portion 111 is provided with the above-mentioned external thread.
In some embodiments, the outer diameter of the flexible joint 12 gradually increases from the opposite ends to the middle position to facilitate the insertion of the flexible joint 12 into the cooling duct of the speed reducer assembly 30. Further, the outer side surface of the elastic connector 12 is an arc surface.
It should be noted that the maximum outer diameter of the elastic connector 12 is slightly larger than the inner diameter of the cooling channel of the speed reducer assembly 30, so that the elastic connector 12 and the cooling channel are in interference fit, the outer diameters of the two opposite ends of the elastic connector 12 along the axial direction of the connecting pipe 11 are smaller than the outer diameter of the middle position of the connecting pipe, the outer diameter of the middle position of the elastic connector 12 is maximum, the outer diameters of the two opposite ends of the elastic connector 12 along the axial direction of the connecting pipe 11 are both smaller than the inner diameter of the cooling channel of the speed reducer assembly 30, and the outer side surface of the arc shape of the elastic connector 12 is combined, so that the insertion of the elastic connector 12 is facilitated.
In practical application, the cross section of the elastic connector 12 is circular, that is, the elastic connector 12 is a spherical part as a whole, so that the elastic connector 12 can be connected with the cooling channel of the speed reducer assembly 30 at multiple angles, and the elastic connector 12 can be further conveniently connected with the cooling channel of the speed reducer assembly 30.
In some embodiments, the outer side surface of the elastic connection head 12 is provided with a plurality of resistance reducing portions, and the plurality of resistance reducing portions are uniformly arranged to reduce resistance when the elastic connection head 12 is inserted into the cooling channel of the speed reducer assembly 30, so as to facilitate assembly.
In practical application, the resistance reducing part is a pit, so that the outer side surface of the elastic connector 12 is a non-smooth surface, thereby reducing the contact area of the elastic connector 12 and a cooling channel of the speed reducer assembly 30, further reducing the assembly resistance and facilitating the assembly.
The utility model also relates to a driving system, which comprises a motor controller 20, a reducer assembly 30 and the pipeline joint in the above embodiment, wherein one end of the connecting pipe 11 in the pipeline joint is connected with the cooling channel of the motor controller 20, and the elastic connector 12 in the pipeline joint is inserted into the cooling channel of the reducer assembly 30 and is in interference fit with the cooling channel.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
