The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

Example 1

The embodiment of the utility model provides a pipeline connecting structure which can be beneficial to improving the stability of pipeline connection and reducing the probability of the pipeline connecting structure being disconnected by external force.

Referring to fig. 1 to 5, the pipe connection structure includes a first connection pipe 1 and a second connection pipe 2.

One end of the first connecting pipe 1 is provided with an annular inserting groove 101 extending along the central line direction of the first connecting pipe 1, the groove wall of the annular inserting groove 101 is provided with an annular limiting groove 102, and the annular limiting groove 102 surrounds the central line of the first connecting pipe 1; one end of the second connecting pipe 2 is provided with an annular inserting portion 201 for inserting connection with the annular inserting groove 101, and the annular inserting portion 201 is provided with a limiting protruding portion 202 for inserting into the annular limiting groove 102.

Specifically, the annular insertion portion 201 is inserted into the annular insertion groove 101, and the limit protrusion 202 is inserted into the annular limit groove 102, so that the annular limit groove 102 forms an obstruction that the limit protrusion 202 is separated outwards, thereby effectively maintaining the connection stability of the first connection pipe 1 and the second connection pipe 2, and reducing the possibility of disconnection of the first connection pipe 1 and the second connection pipe 2 due to the action of external force.

It should be noted that the first connection pipe 1 and the second connection pipe 2 may be used for a cooling device in a battery to supply a liquid cooling medium. For example, the connection structure between the liquid supply pipe and the cooling plate may be a pipe connection structure in this embodiment, that is, the cooling plate is provided with a first connection pipe 1 or a second connection pipe 2, and the liquid supply pipe is correspondingly provided with the second connection pipe 2 or the first connection pipe 1; or, two adjacent liquid cooling plates or two adjacent harmonica pipe structures can be connected by adopting the pipeline connecting structure in the embodiment.

Optionally, the spacing protruding portion 202 is annular protruding, and the bellied structure of annular can be inconsistent with the cell wall of annular spacing groove 102, and annular protruding is blocked to the cell wall of annular spacing groove 102 to avoid spacing protruding portion 202 to deviate from annular spacing groove 102, and then promoted the connection stability of first connecting pipe 1 and second connecting pipe 2. Alternatively, the limiting boss 202 includes a plurality of protrusions circumferentially arranged in an array around the center line of the second connection pipe 2, and the plurality of protrusions of the circumferential array are abutted against the groove wall of the annular limiting groove 102 from all directions in the circumferential direction, so as to avoid disconnection of the first connection pipe 1 and the second connection pipe 2, and the number of the protrusions is not less than three. Preferably, the groove wall of one side of the annular limiting groove 102, which is close to the annular inserting groove 101, is perpendicular to the central line of the first connecting pipe 1, and the abutting surface of the limiting boss 202, which is used for abutting against the groove wall of one side of the annular limiting groove 102, which is close to the annular inserting groove 101, is also perpendicular to the central line of the first connecting pipe 1.

Optionally, the notch of the annular inserting groove 101 is provided with a guiding inclined plane 1001, and the limiting boss 202 is provided with a guiding surface 1002 sliding along the guiding inclined plane 1001 to enable the limiting boss 202 to slide into the annular limiting groove; as can be seen from fig. 5, the arrangement of the guide inclined surface 1001 and the guide surface 1002 can make the limit projection 202 easier to be inserted into the annular limit groove 102, so as to facilitate installation.

The first groove wall 1003 of the annular inserting groove 101, which is close to the guide inclined surface 1001, is perpendicular to the inserting direction of the annular inserting part 201, and the limiting surface 1004 parallel to the first groove wall 1003 is arranged on the limiting convex part 202; when the limit protrusion 202 is inserted into the annular limit groove 102, the limit surface 1004 and the first groove wall 1003 are disposed opposite to each other. When the limiting boss 202 is easier to be inserted into the annular limiting groove 102, the limiting surface 1004 and the first groove wall 1003 which are oppositely arranged can effectively prevent the limiting boss 202 from sliding out of the annular limiting groove 102, so that the limiting boss 202 can only move along the central line direction of the first connecting pipe 1.

Alternatively, the first connection pipe 1 includes a main pipe body 11 and a housing portion 12 provided around the outer periphery of the main pipe body 11, the housing portion 12 is fixedly connected with the main pipe body 11, and the housing portion 12 and the main pipe body 11 form an annular socket 101. As shown in fig. 4, the annular socket 201 is inserted into the annular socket 101 and is limited by the annular limiting groove 102, thereby improving the connection stability of the first connection pipe 1 and the second connection pipe 2.

Alternatively, as shown in fig. 4, an annular limiting groove 102 is provided on the housing portion 12, and a limiting boss 202 is provided on an outer peripheral surface of the annular insertion portion 201. The housing portion 12 may have some ability to elastically deform so that the retention tabs 202 are more easily inserted into the annular retention slots 102.

Alternatively, the annular limiting groove 102 is disposed on a side surface of the main pipe body 11 close to the outer shell portion 12, and the limiting boss 202 is disposed on an inner pipe surface of the annular plug portion 201. At this time, the annular insertion portion 201 may have a certain elastic deformability, so that the limit projection 202 is more easily inserted into the annular limit groove 102.

Alternatively, the outer shell portion 12 includes a support portion 121 fixedly connected to the main tube body 11 and an elastically deforming portion 122 connected to the support portion 121, the elastically deforming portion 122 surrounding the main tube body 11, and a gap for forming the annular insertion groove 101 is provided between the elastically deforming portion 122 and the main tube body 11. Specifically, the elastic deformation portion 122 may deform in a direction away from the main tube body 11, so that the notch of the annular insertion groove 101 becomes large, and the limit projection 202 can be inserted into the annular insertion groove 101.

Optionally, the pipe connection structure further comprises a splitter plate 3 and a plug connection pipe 4 arranged on the splitter plate 3; the split plate 3 may be connected with a harmonica pipe or a liquid cooling plate, for example, the split plate 3 in fig. 1 and 2 is provided with a water outlet, and the harmonica pipe or the liquid cooling plate may be connected with the water outlet in a sealing manner. Of course, the harmonica pipe or the liquid cooling plate can be in sealed connection with the water outlet by other means, such as welding, gluing, etc.

The plug connection pipe 4 is used for plug connection with the first connection pipe 1 or the second connection pipe 2, and flexible sealing layers 5 are arranged on the inner pipe wall of the first connection pipe 1 and the inner pipe wall of the second connection pipe 2; the provision of the flexible sealing layer 5 can increase the connection tightness when the plug connection pipe 4 is inserted into the inner pipe wall of the first connection pipe 1 or into the inner pipe wall of the second connection pipe 2. In addition, the arrangement of the flexible sealing layer 5 can improve the displacement fault tolerance of the pipeline in the assembly process.

The flexible sealing layer 5 on the first connecting pipe 1 is used for sealing the gap between the plug-in connecting pipe 4 and the inner pipe wall of the first connecting pipe 1; the flexible sealing layer 5 on the second connecting pipe 2 is used for sealing the gap between the plug-in connecting pipe 4 and the inner pipe wall of the second connecting pipe 2.

Optionally, an annular sealing projection 41 is also provided on the outer tube wall of the plug connection tube 4. The annular sealing protrusion 41 presses the flexible sealing layer 5, thereby making the sealing of the pipe connection better.

Optionally, an annular sealing groove 103 for mounting the sealing ring 6 is further provided on the groove wall of the annular plugging groove 101, and the annular sealing groove 103 surrounds the center line of the first connecting pipe 1. The sealing ring 6 is installed in the annular sealing groove 103, so that a gap between the annular inserting portion 201 and the elastic deformation portion 122 is sealed, and the condition of liquid leakage is avoided.

Alternatively, the width of the limit projection 202 is smaller than the width of the annular limit groove 102 in the direction along the center line of the first connection pipe 1. Specifically, on the premise that the width of the limiting boss 202 is smaller than that of the annular limiting groove 102, the limiting boss 202 can be adjusted in position along the central line direction of the first connecting pipe 1 in the annular limiting groove 102, so that the connecting structure of the first connecting pipe 1 and the second connecting pipe 2 connected in series has certain floatability. It should be specifically explained that, in the cooling structure of the battery, the interval between the two liquid cooling plates needs to be matched with the thickness of the battery, and the connecting structure of the first connecting pipe 1 and the second connecting pipe 2 connected in series has certain floatability, so that the two liquid cooling plates can better attach to the two opposite side surfaces of the battery, the cooling effect is improved, and the influence of the processing error of the battery shell or the length error of the pipeline on the cooling effect of the battery is reduced. Of course, the cooling plate may be replaced with a harmonica tube or other specific component for cooling the battery.
