Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and in particular to a temperature-adjustable battery assembly and system. Background Art

[0002] Operating batteries at excessively high temperatures accelerates their aging process, affecting their performance and lifespan. Temperature-adjustable battery components and systems monitor the battery's operating temperature in real time and adjust it to ensure it operates within the optimal temperature range. This not only slows down battery aging but also significantly improves its service life. Furthermore, operating batteries at extreme temperatures can lead to safety issues such as thermal runaway, spontaneous combustion, and even explosion. Temperature-adjustable battery components and systems effectively prevent overheating by timely monitoring battery temperature and implementing appropriate cooling or heating measures.

[0003] Among the existing published technical documents, Chinese Patent Publication No. CN111682285A discloses a temperature-adjustable battery. The battery pack has a first channel that connects the heat dissipation channel and the inner cavity of the base through an insertion protrusion. The top cover has an inner cavity, a second air pump, and multiple holes communicating with the inner cavity. The top cover has a first external vent at one end and a second external vent at the other end. A cooling fan is fixed to the first external vent. Liquid is contained in the heat dissipation channel. This battery technology allows for adjustable heat dissipation mode, allowing the battery's operating temperature to be adjusted according to ambient temperature. However, this battery assembly still presents the following usage issues.

[0004] When the battery assembly is temperature-regulated, although temperature sensing can be used and a fan provides cooling when the set temperature is exceeded, during the cooling process, the air outlet position and the cooling liquid position are both fixed contact positions, which makes it difficult to synchronously perform flow contact cooling on the upper and lower surfaces of each battery cell of the battery assembly, and difficult to perform large-area flow cooling on the outside and interval parts of each battery cell, resulting in temperature regulation blind spots and poor temperature regulation effects. Therefore, a temperature-adjustable battery assembly and system are provided. Summary of the Invention

[0008] When this technical solution is used, the electric cylinder pushes the socket plate to move right, the socket plate drives the concave plate to move right, the two linkage shafts move right along the inner wall of the battery housing, the linkage bar drives the two connecting columns to move right, and the hinge block drives the two hinge shafts to move right. At the same time, the two socket sliders respectively drive the distance between the two rectangular cooling tubes to increase. When the rectangular cooling tube moves backward, it will drive the sensing block to move backward synchronously. The distance sensor realizes distance sensing of the sensing block. When the sensing block approaches the proximity sensor, the controller drives the electric cylinder to drive the socket plate to move left. When the socket plate moves left, the socket plate will drive the concave plate to move left, the two linkage shafts will respectively drive the two linkage bars to move left, the two linkage bars will respectively drive the two connecting columns to move left, and the hinge block will drive the two hinge shafts to move left. At the same time, the two hinged shafts drive the two sleeve rods to move left respectively, and the two sleeve rods drive the two support shafts closer to each other respectively, and the two sleeve sliders drive the two rectangular cooling tubes closer to each other respectively. The multiple rectangular cooling tubes at the bottom of the battery cell are displaced and moved back and forth. At the same time, the multiple rectangular cooling tubes above the battery cell can also be displaced and moved back and forth laterally, realizing position adjustment without dead angles.

[0009] Preferably, the diversion and temperature control linkage assembly includes a plurality of output hoses arranged on one side of the linkage bar; the top end of the output hose is connected to an output rectangular tube, the output rectangular tube and the rectangular cooling tube are both fixedly connected to the output hose, one side of the output rectangular tube is welded to a diversion branch tube, and one end of the diversion branch tube is fixedly connected to an output collecting tube; one side of the output collecting tube is fixedly connected to a detection tube, and a temperature sensor is plugged into the outer wall of the detection tube, and the temperature sensor is used to sense temperature;

[0010] The bottom end of the rectangular cooling tube is fixedly connected to an injection hose at a position away from the output hose, and an injection diverter pipe is installed at the top of the injection hose. Multiple injection hoses are fixedly connected to the injection diverter pipe, and the injection diverter pipe and the output rectangular tube are fixedly connected to the battery housing. One side of the injection diverter pipe is fixedly connected to a guide pipe; one end of the guide pipe is fixedly connected to a boost pipe, and a boost pump is fixedly installed on one side of the boost pipe. The boost pump is used to boost air. Multiple output hoses are arranged equidistantly from front to back, and the output hose is made of rubber. The two guide pipes are symmetrically arranged about the middle of the boost pipe, and the guide pipe and the boost pipe are both made of carbon fiber.

[0011] When this technical solution is used, the boost pump delivers external cooling air to the boost pipe. Simultaneously, the boost pipe pumps the cooling air into the boost hose, which then pumps it into the rectangular frame pipe. The rectangular frame pipe then diverts the air into two rectangular spacer pipes, and the cooling air is pumped into the diversion connecting pipe. The hot air after heat exchange is then delivered to the connecting hose and then to the injection diversion pipe through the guide pipe. The cooling air is then diverted along the injection diversion pipe into multiple injection hoses, which are then diverted by the multiple injection hoses into multiple rectangular cooling pipes. The cooling air is then pumped into the output rectangular pipe through the output hose, diverted by the output rectangular pipe into the output rectangular pipe, diverted along the output rectangular pipe into the diversion branch pipe, and then collected along the output collection pipe and delivered to the detection pipe. The detection pipe then discharges the hot air. When the temperature value sensed by the temperature sensor is higher than the temperature value set by the controller, the electric cylinder is activated by the controller.

[0012] Preferably, the internal interval temperature regulating mechanism includes a swing motor fixedly mounted on one side of the battery housing; the output end of the swing motor is fixedly connected to a linkage rod, and the linkage rod is rotatably connected to the battery housing, a sliding frame is fixedly mounted on one side of the outer wall of the linkage rod, and the inner wall of the sliding frame is slidably connected to a limited sliding shaft at a position away from the linkage rod, and one end of the limited sliding shaft is fixedly mounted on a rectangular frame tube, and the battery housing and the rectangular frame tube are both slidably connected to the sliding frame; two rectangular spacer tubes are fixedly connected on one side of the inner wall of the rectangular frame tube, and a shunt connecting tube fixedly connected to the rectangular frame tube is provided between the two rectangular spacer tubes;

[0013] A connecting hose is fixedly connected to the inner wall of the rectangular frame tube, located on one side of the rectangular spacer tube. A boost hose is installed on one side of the shunt tube, and the boost hose is fixedly connected to the rectangular frame tube. Spacer sleeves are installed above and below the rectangular frame tube, and both of these spacer sleeves are fixedly connected to the battery housing. Multiple battery cells are fixedly connected to the inner walls of these spacer sleeves. The two rectangular spacer tubes are symmetrically arranged about the shunt tube, and both are fixedly connected to the shunt tube.

[0014] When this technical solution is used, the swing motor drives the linkage rod to rotate clockwise, and the sliding frame causes the limit slide to move downward. The limit slide will drive the rectangular frame tube to move downward, and the rectangular frame tube will cool and adjust the temperature along the outer parts of multiple battery cells. The two rectangular spacer tubes cool and adjust the temperature at the intervals between multiple battery cells, and the shunt connecting tube cools and adjusts the temperature along the intervals between multiple battery cells. The swing motor drives the linkage rod to rotate counterclockwise, and the sliding frame causes the limit slide to move upward, and the rectangular frame tube slides upward along the inner wall of the battery shell. The rectangular frame tube drives the two rectangular spacer tubes to move upward, and the two rectangular spacer tubes cool and adjust the temperature at the intervals between multiple battery cells.

[0015] A temperature-adjustable battery system comprises a controller fixedly arranged below a swing motor.

[0016] The present invention has the following advantages:

[0017] 1. The present invention provides a double-sided linkage temperature control mechanism. The electric cylinder pushes the sleeve plate to move right, and the two linkage shafts move right along the inner wall of the battery shell. The two hinged shafts push the two sleeve rods to move right, and the two sleeve sliders respectively drive the distance between the two rectangular cooling tubes to increase. When the sleeve plate moves to the left, the sleeve plate will drive the concave plate to move left, and the two sleeve rods respectively drive the two support shafts to approach each other. The two support shafts respectively drive the two sleeve sliders to approach each other, and the two sleeve sliders respectively drive the two rectangular cooling tubes to approach each other. The multiple rectangular cooling tubes at the bottom of the battery cell are displaced and moved back and forth, and the multiple rectangular cooling tubes above the battery cell can also be displaced and moved back and forth laterally, realizing displacement temperature control without dead angles, and the battery pack temperature self-regulation effect is better.

[0018] 2. The present invention uses a flow-guiding and temperature-regulating linkage assembly. The boost pump delivers external cooling air to the boost pipe, which then injects the cooling air into the boost hose. The boost hose then injects the cooling air into the rectangular frame pipe. The rectangular frame pipe, two rectangular spacer pipes, and the shunt connecting pipe all cool down multiple battery cells. The cooling air is diverted along the injection shunt pipe into multiple injection hoses, injected into the output rectangular pipe through the output hose, and then guided by the output rectangular pipe to the inside of the output rectangular pipe. The detection pipe then discharges the hot air. At the same time, a temperature sensor is used to sense the temperature of the hot air discharged from the detection pipe. This allows for boosting and connecting operations, ensuring that multiple rectangular cooling pipes can move laterally and that the rectangular frame pipe can move vertically.

[0019] 3. The present invention sets an internal interval temperature control mechanism. The controller drives the swing motor to rotate clockwise, the linkage rod drives the sliding frame to rotate clockwise, and the rectangular frame tube slides downward along the inner wall of the battery shell. In this way, the rectangular frame tube cools and controls the temperature along the peripheral parts of multiple battery cells. The two rectangular spacer tubes and the shunt connecting tube cool and control the temperature at the intervals of multiple battery cells. At the same time, the rectangular frame tube cools and controls the temperature along the peripheral parts of multiple battery cells. The swing motor drives the linkage rod to rotate counterclockwise. The two rectangular spacer tubes, the rectangular frame tube and the shunt connecting tube realize reciprocating cooling and temperature control from bottom to top. The temperature control contact area is wider and the temperature control effect of the battery pack is better.

[0020] Based on the mutual influence of the above multiple functions, first, the multiple rectangular cooling tubes at the bottom of the battery cell are displaced and moved back and forth, and the multiple rectangular cooling tubes above the battery cell can also be displaced and moved laterally back and forth. Secondly, the rectangular frame tube, two rectangular spacer tubes, and shunt connecting tube all cool the multiple battery cells, and then the two rectangular spacer tubes, rectangular frame tube, and shunt connecting tube achieve bottom-up reciprocating cooling and temperature regulation. In summary, the upper and lower surfaces of each battery cell can be simultaneously subjected to flow contact cooling, and the exterior and spacing areas of each battery cell can be subjected to large-area flow cooling, avoiding temperature regulation blind spots and achieving better temperature regulation effects for the battery pack.

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0036] As attached Figure 1 -Attached Figure 11A temperature-adjustable battery assembly is shown, and the temperature-adjustable battery assembly is provided with a double-sided linkage temperature control mechanism, a flow-guiding temperature control linkage component, and an internal interval temperature control mechanism.

When the sensing block 19 approaches the proximity sensor 17, the controller 42 drives the electric cylinder 2 to drive the sleeve plate 3 to move left, thereby realizing precise control operation.

[0040] In this technical solution, as shown in the attached Figure 6 -Attached Figure 10 As shown, the diversion and temperature control linkage assembly includes a plurality of output hoses 20 arranged on one side of the linkage bar 6; the top end of the output hose 20 is connected to the output rectangular tube 21, and the output rectangular tube 21 and the rectangular cooling tube 13 are fixedly connected to the output hose 20; one side of the output rectangular tube 21 is welded to a diversion branch pipe 22, and one end of the diversion branch pipe 22 is fixedly connected to an output collecting pipe 23; one side of the output collecting pipe 23 is fixedly connected to a detection tube 24, and a temperature sensor 25 is inserted into the outer wall of the detection tube 24, and the temperature sensor 25 is used to sense temperature.

[0041] An injection hose 26 is fixedly connected to the bottom end of the rectangular cooling tube 13, away from the output hose 20. An injection shunt pipe 27 is installed at the top of the injection hose 26. Multiple injection hoses 26 are fixedly connected to the injection shunt pipe 27. The injection shunt pipe 27 and the output rectangular tube 21 are both fixedly connected to the battery housing 1. A guide pipe 28 is fixedly connected to one side of the injection shunt pipe 27; one end of the guide pipe 28 is fixedly connected to a boost pipe 29, and a boost pump 30 is fixedly installed on one side of the boost pipe 29. The boost pump 30 is used to pressurize the air. Multiple output hoses 20 are arranged in equal intervals from front to back, and the output hoses 20 are made of rubber. Two guide pipes 28 are symmetrically arranged about the middle of the boost pipe 29. Both the guide pipe 28 and the boost pipe 29 are made of carbon fiber.

[0042] In this technical solution, as shown in the attached Figure 6 -Attached Figure 11 As shown, the internal interval temperature control mechanism includes a swing motor 31 fixedly mounted on one side of the battery housing 1; the output end of the swing motor 31 is fixedly connected to a linkage rod 32, and the linkage rod 32 is rotatably connected to the battery housing 1, a sliding frame 33 is fixedly mounted on one side of the outer wall of the linkage rod 32, and a limiting sliding shaft 34 is slidably connected to the inner wall of the sliding frame 33 and away from the linkage rod 32, and a rectangular frame tube 35 is fixedly mounted on one end of the limiting sliding shaft 34, and the battery housing 1 and the rectangular frame tube 35 are both slidably connected to the sliding frame 33; two rectangular spacer tubes 36 are fixedly connected to one side of the inner wall of the rectangular frame tube 35, and a shunt connecting tube 37 fixedly connected to the rectangular frame tube 35 is provided between the two rectangular spacer tubes 36.

[0043] A connecting hose 38 is fixedly connected to the inner wall of the rectangular frame tube 35 and located on one side of the rectangular spacer tube 36. A boost hose 39 is provided on one side of the shunt connecting tube 37, and the boost hose 39 is fixedly connected to the rectangular frame tube 35. A spacer sleeve 41 is provided above and below the rectangular frame tube 35. Both spacer sleeves 41 are fixedly connected to the battery housing 1. Multiple battery cells 40 are fixedly connected to the inner wall of the spacer sleeve 41. The two rectangular spacer tubes 36 are symmetrically arranged about the shunt connecting tube 37 and are fixedly connected to the shunt connecting tube 37.

[0044] A temperature-adjustable battery system includes a controller 42 fixedly arranged below a swing motor 31, so as to sense the temperature of the hot air discharged from a detection tube 24 through a temperature sensor 25. When the temperature value sensed by the temperature sensor 25 is higher than the temperature value set by the controller 42, the electric cylinder 2 is started by the controller 42 to realize the driving operation of the electric cylinder 2.

[0045] The method for using the temperature-adjustable battery assembly of the present invention is as follows:

[0046] In step 1, when the flow diversion and temperature control are linked, the controller 42 activates the boost pump 30, which delivers external cooling air to the boost pipe 29. The boost pipe 29 then pumps the cooling air into the two diversion pipes 28. Simultaneously, the boost pipe 29 pumps the cooling air into the boost hose 39, which then flows into the rectangular frame pipe 35. The rectangular frame pipe 35 then diverts the cooling air into the two rectangular spacer pipes 36, and into the diversion connecting pipe 37. In this way, the rectangular frame pipe 35, the two rectangular spacer pipes 36, and the diversion connecting pipe 37 all cool the multiple battery cells 40. The hot air after heat exchange is then delivered to the connecting hose 38, where it is then collected into the output manifold 23. The air is then delivered through the diversion pipe 28 to the injection diversion pipe 27, where it is then diverted into the multiple injection hoses 26. The multiple injection hoses 26 then flow into the multiple rectangular cooling pipes 13.

[0047] After absorbing heat inside the rectangular cooling tube 13, the hot air is transported to the output hose 20, then poured into the output rectangular tube 21 through the output hose 20. The hot air is then diverted by the output rectangular tube 21 and collected inside the output rectangular tube 21. The hot air is then diverted along the output rectangular tube 21 to the inside of the diversion branch pipe 22. The hot air then enters the output collection pipe 23 through the diversion branch pipe 22. After being collected along the output collection pipe 23, the hot air is transported to the detection pipe 24 and discharged through the detection pipe 24. The detection pipe 24 discharges the hot air. Simultaneously, the hot air discharged from the detection pipe 24 is sensed by the temperature sensor 25. When the temperature value sensed by the temperature sensor 25 is higher than the temperature value set by the controller 42, the controller 42 activates the electric cylinder 2.

[0048] During step 2, double-sided linkage temperature adjustment, the electric cylinder 2 pushes the sleeve plate 3 to the right. This sleeve plate 3 moves right along the outer wall of the electric cylinder 2, simultaneously driving the concave plate 4 to the right. This concave plate 4 causes the two linkage shafts 5 to move right. Simultaneously, the two linkage shafts 5 move right along the inner wall of the battery housing 1, and the two linkage shafts 5 each drive the two linkage bars 6 to the right. The linkage bars 6 drive the two connecting columns 7 to the right. The connecting columns 7 cause the hinge block 8 to move right. The hinge block 8 drives the two hinge shafts 9 to the right. The two hinge shafts 9 cause the two sleeve rods 10 to move right. The sleeve rods 10 drive the support shaft 11 backward, and the support shaft 11 drives the sleeve slide 12 backward. The sleeve slide 12 moves backward along the outer wall of the slide bar 14 and the inner wall of the guide frame 15. Simultaneously, the two sleeve slides 12 cause the distance between the two rectangular cooling tubes 13 to increase. When rectangular cooling tube 13 moves backward, it drives sensing block 19 to move backward synchronously. Battery housing 1 supports sleeve bracket 16, which in turn supports distance sensor 18. Distance sensor 18 senses the distance of sensing block 19, and sensing block 19 approaches proximity sensor 17. When sensing block 19 approaches proximity sensor 17, controller 42 drives electric cylinder 2 to move sleeve plate 3 leftward.

[0049] When the socket plate 3 moves left, it drives the concave plate 4 leftward. The concave plate 4 causes the two linkage shafts 5 to move leftward. The two linkage shafts 5 respectively drive the two linkage bars 6 leftward. The two linkage bars 6 respectively drive the two connecting columns 7 leftward. The connecting columns 7 drive the hinge block 8 leftward. The hinge block 8 drives the two hinge shafts 9 leftward. Simultaneously, the two hinge shafts 9 respectively drive the two sleeve rods 10 leftward. The two sleeve rods 10 respectively drive the two support shafts 11 closer together. The two support shafts 11 respectively drive the two socket sliders 12 closer together. The two socket sliders 12 respectively drive the two rectangular cooling tubes 13 closer together. In this way, the multiple rectangular cooling tubes 13 at the bottom of the battery cell 40 are shifted and moved back and forth. The multiple rectangular cooling tubes 13 can increase the moving contact area. At the same time, the multiple rectangular cooling tubes 13 above the battery cell 40 can also be shifted and moved laterally back and forth, achieving no-dead-angle shifting and temperature adjustment, and rapidly cooling the upper and lower parts of the battery cell 40.

[0050] Step 3: During internal temperature adjustment, the controller 42 drives the swing motor 31 to rotate clockwise. The swing motor 31 drives the linkage rod 32 to rotate clockwise, which in turn drives the slide frame 33 to rotate clockwise. The slide frame 33 causes the limit slide shaft 34 to move downward. Simultaneously, the limit slide shaft 34 slides along the inner wall of the slide frame 33 and drives the rectangular frame tube 35 downward. The rectangular frame tube 35 slides downward along the inner wall of the battery housing 1, thereby cooling and regulating the temperature along the outer portions of the multiple battery cells 40. The rectangular frame tube 35 drives the two rectangular spacer tubes 36 downward. The two rectangular spacer tubes 36 cool and regulate the temperature of the spaces between the multiple battery cells 40. Simultaneously, the rectangular frame tube 35 drives the shunt connecting tube 37 downward. The shunt connecting tube 37 cools and regulates the temperature along the spaces between the multiple battery cells 40.

[0051] Then, the controller 42 drives the swing motor 31, and the swing motor 31 drives the linkage rod 32 to rotate counterclockwise, and the linkage rod 32 drives the slide frame 33 to rotate counterclockwise, and the slide frame 33 causes the limit slide shaft 34 to move upward, and the limit slide shaft 34 will drive the rectangular frame tube 35 to move upward, and the rectangular frame tube 35 slides upward along the inner wall of the battery shell 1, and the rectangular frame tube 35 drives the two rectangular spacer tubes 36 to move upward, and the two rectangular spacer tubes 36 cool and regulate the temperature at the intervals of multiple battery cells 40. As the swing motor 31 continuously rotates back and forth, the two rectangular spacer tubes 36, the rectangular frame tube 35, and the shunt connecting tube 37 can realize bottom-up reciprocating cooling and temperature regulation, and the temperature regulation contact area is wider, avoiding the existence of contact dead angles.

[0052] Step 4: When temperature control stops, the hot air output from the inside of the detection tube 24 is continuously sensed by the temperature sensor 25. When the temperature sensed by the temperature sensor 25 reaches the safe temperature set by the controller 42, the swing motor 31 and the electric cylinder 2 are turned off by the controller 42, thereby reducing energy loss.
