[0004] The present application provides a sealing ring assembly mechanism and a battery production device, which can improve battery production efficiency.

[0005] In the first aspect, the present application provides a sealing ring assembly mechanism, comprising: a sleeve body, a pressure block and an assembly shaft; the pressure block is connected to one end of the sleeve body, the pressure block is movably connected to the sleeve body, and at least two pressure blocks are enclosed to form an avoidance hole; the assembly shaft passes through the avoidance hole and is connected to the sleeve body; wherein each pressure block is movably arranged in a direction away from the assembly shaft, the assembly shaft is used to sleeve the sealing ring, and the assembly shaft protrudes from one end of the pressure block away from the sleeve body, so that the sealing ring can abut against the end of the pressure block away from the sleeve body.

[0006] In the technical solution of the embodiment of the present application, at least two pressing blocks are enclosed to form an avoidance hole, the assembly shaft passes through the avoidance hole and protrudes from the end of the pressing block away from the sleeve, the sealing ring can be sleeved on the assembly shaft and abutted against the end of the pressing block away from the sleeve, and the assembly shaft is used to fix the position of the sealing ring. The pressing block is movably connected to the sleeve, and each pressing block can be movably arranged in a direction away from the assembly shaft to increase the diameter of the avoidance hole. The cooling pipe joint abuts against the end of the pressing block away from the sleeve, and the sealing ring is located between the pressing block and the cooling pipe joint. When the cooling pipe joint moves in a direction close to the sleeve, it can push each pressing block to move in a direction away from the assembly shaft to separate the pressing block and the assembly shaft. When the cooling pipe joint moves relative to the pressing block in a direction close to the sleeve, the pressing block presses the sealing ring to move toward the end of the cooling pipe joint away from the sleeve, so as to sleeve the sealing ring to the outer periphery of the cooling pipe joint. This process has fewer installation steps, thereby improving the installation efficiency of the sealing ring. In addition, the sealing ring is pressed by the pressing block to move toward the end of the cooling pipe joint away from the sleeve body, and there is no need to expand the sealing ring to be larger than the outer diameter of the cooling pipe joint, thereby reducing the risk of plastic deformation of the sealing ring and helping to improve the reliability of the battery.

[0007] According to some embodiments of the present application, the pressing block includes a first sub-section and a second sub-section connected to each other along a first direction, the second sub-sections of at least two pressing blocks are enclosed to form an avoidance hole, the assembly axis passes through the avoidance hole along the first direction and protrudes from the side of the second sub-section away from the first sub-section, and the first sub-section is rotatably connected to the sleeve body so that the second sub-section can be deflected in a direction close to or away from the assembly axis. The second sub-section is rotatably connected to the sleeve body through the first sub-section, and when the second sub-section is deflected in a direction away from the assembly axis, the second sub-section is spaced apart from the assembly axis to increase the diameter of the avoidance hole, so that part of the cooling pipe joint can be extended into the avoidance hole.

[0008] According to some embodiments of the present application, at least two mounting grooves are provided at one end of the sleeve body facing the pressing block, and the at least two mounting grooves are arranged at intervals around the assembly axis, and the first subsection of each pressing block is arranged in each mounting groove.

In the process of the cooling pipe joint moving toward the sleeve body, the cooling pipe joint is sleeved on the first sub-segment and abuts against the side of the second sub-segment facing the first sub-segment, and the end of the cooling pipe joint presses against the assembly shaft, reducing the risk of the first sub-segment extending too deep into the cooling pipe joint and causing damage to the inside of the cooling pipe joint.

[0016] According to some embodiments of the present application, the sealing ring assembly mechanism also includes a reset member, which is arranged between the assembly shaft and the sleeve body, and is used to provide a reset force to the assembly shaft away from the sleeve body, so that the assembly shaft moves to the side of the second section facing the first section to abut against the second section, and the first section protrudes from the side of the second section away from the first section, so as to install a sealing ring for the next cooling pipe joint.

[0037] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0038] For batteries, a suitable ambient temperature is one of the keys to ensuring battery performance. When the battery temperature is too low, the movement speed of the metal ions in the battery cells is low, the ability of the metal ions to embed into the pole pieces is also low, and the charging and discharging capacity is low. Heat is generated during the battery charging and discharging process. When the battery temperature is too high, the battery is prone to safety hazards such as thermal runaway and explosion. Therefore, the battery generally also includes a thermal management component. The thermal management component is provided with a cooling circuit to accommodate the cooling medium to adjust the temperature of multiple battery cells, so that the battery is within a suitable temperature range, ensuring better charging and discharging capacity and higher safety.

[0039] In order to improve the sealing performance of the cooling pipe joint of the cooling pipeline, a sealing ring needs to be installed on the cooling pipe joint to reduce leakage at the cooling pipe joint. However, the process of installing the sealing ring on the cooling pipe joint is relatively cumbersome, which affects the production efficiency of the battery. In addition, the assembly method in the related technology requires the sealing ring to be enlarged to a larger diameter than the outer diameter of the cooling pipe joint and stay for a longer time, which will increase the risk of plastic deformation of the sealing ring and affect the sealing effect and service life of the product.

[0040] In view of this, in order to facilitate improving the efficiency of installing the sealing ring on the cooling pipe joint, the present application provides a sealing ring assembly mechanism, including a pressure block 200 and an assembly shaft 300, at least two pressure blocks 200 enclose a avoidance hole 230; the assembly shaft 300 is used to sleeve the sealing ring, and the cooling pipe joint is sleeved on the assembly shaft, and the cooling pipe joint pushes the pressure block 200 to move in a direction away from the assembly shaft 300 to increase the aperture of the avoidance hole 230. During the process of the cooling pipe joint extending into the avoidance hole 230, the pressure block pushes the sealing ring to slide into the assembly position of the cooling pipe joint. The assembly of the sealing ring does not require the process of expanding the sealing ring and then sleeved into the cooling pipe joint, which solves the problem of shortening the life of the sealing ring and damaging the sealing ring due to excessive expansion of the sealing ring during the assembly process, and at the same time improves the assembly efficiency of the sealing ring.

[0041] The sealing ring assembly mechanism in the embodiment of the present application is not limited to installing sealing rings on cooling pipe joints. Other types of joints or pipes that require sealing rings can also use the sealing ring assembly mechanism in the embodiment of the present application.

[0042] First, as Figures 1 to 3 As shown, the present application provides a sealing ring assembly mechanism, including: a sleeve 100, a pressure block 200 and an assembly shaft 300, the pressure block 200 is connected to one end of the sleeve 100, the pressure block 200 is movably connected to the sleeve 100, at least two pressure blocks 200 enclose a avoidance hole 230; the assembly shaft 300 passes through the avoidance hole 230 and is connected to the sleeve 100; wherein each pressure block 200 is movably arranged in a direction away from the assembly shaft 300, the assembly shaft 300 is used for sleeve-mounting the sealing ring, and the assembly shaft 300 protrudes from one end of the pressure block 200 away from the sleeve 100, so that the sealing ring can abut against the end of the pressure block 200 away from the sleeve 100.

[0043] Exemplarily, the pressing block 200 may be movably connected to the sleeve 100, such that the pressing block 200 is rotatably connected to the sleeve 100, so that one end of each pressing block 200 away from the sleeve 100 can be rotatably arranged in a direction away from the assembly axis 300. The pressing block 200 may be movably connected to the sleeve 100, or the pressing block 200 may be slidably connected to the sleeve 100, so that each pressing block 200 can be slidably arranged in a radial direction of the sleeve 100 in a direction away from the assembly axis 300.

[0044] For example, the number of the pressing blocks 200 may be two, and the two pressing blocks 200 enclose the avoidance hole 230. Alternatively, the number of the pressing blocks 200 may be more than three, and the more than three pressing blocks 200 enclose the avoidance hole 230 together.

[0045] In the solution of the embodiment of the present application, at least two pressing blocks 200 enclose to form an avoidance hole 230, the assembly shaft 300 passes through the avoidance hole 230 and protrudes from the end of the pressing block 200 away from the sleeve 100, the sealing ring can be sleeved on the assembly shaft 300 and abut against the end of the pressing block 200 away from the sleeve 100, and the assembly shaft 300 is used to fix the position of the sealing ring. The pressing block 200 is movably connected to the sleeve 100, and each pressing block 200 is movably arranged in a direction away from the assembly shaft 300 to increase the diameter of the avoidance hole 230. The cooling pipe joint abuts against the end of the pressing block 200 away from the sleeve 100, and the sealing ring is located between the pressing block 200 and the cooling pipe joint. When the cooling pipe joint moves in the direction close to the sleeve 100, it can push each pressing block 200 to move in the direction away from the assembly axis 300, so that the pressing block 200 and the assembly axis 300 are separated. When the cooling pipe joint moves relative to the pressing block 200 in the direction close to the sleeve 100, the pressing block 200 presses the sealing ring to move toward the end of the cooling pipe joint away from the sleeve 100, so that the sealing ring is sleeved on the outer periphery of the cooling pipe joint. During the installation of the sealing ring, the sealing ring is sleeved on the assembly axis 300, and then the cooling pipe joint is sleeved on the assembly axis 300 and the assembly axis 300 is pressed toward the sleeve 100, so that the sealing ring can be sleeved on the cooling pipe joint. There are fewer installation steps, which can improve the installation efficiency of the sealing ring and improve the production efficiency of the battery. Furthermore, the sealing ring is pressed by the pressing block 200 to move toward the end of the cooling pipe joint away from the sleeve 100, and there is no need to expand the sealing ring to be larger than the outer diameter of the cooling pipe joint, thereby reducing the risk of plastic deformation of the sealing ring and helping to improve the reliability of the battery.

[0046] Optionally, the shape of the side of the pressing block 200 facing the assembly shaft 300 is adapted to the outer surface of the assembly shaft 300. For example, the assembly shaft 300 is a cylindrical structure, and the side of the pressing block 200 facing the assembly shaft 300 is an arc surface. The diameter of the avoidance hole 230 formed by the arc surfaces of multiple pressing blocks 200 is equal to the outer diameter of the assembly shaft 300.

[0047] like Figures 1 to 3 As shown, in some optional embodiments, the pressing block 200 includes a first section 210 and a second section 220 interconnected along a first direction X, the second sections 220 of at least two pressing blocks 200 enclose a avoidance hole 230, the assembly axis 300 passes through the avoidance hole 230 along the first direction X and protrudes from a side of the second section 220 away from the first section 210, and the first section 210 is rotatably connected to the sleeve body 100 so that the second section 220 can be deflected in a direction close to or away from the assembly axis 300.

[0048] Exemplarily, the second subsections 220 of two adjacent pressing blocks 200 are arranged in contact with each other to enclose the avoidance hole 230, or the second subsections 220 of two adjacent pressing blocks 200 are arranged at intervals to enclose the avoidance hole 230. In the embodiment of the present application, four pressing blocks 200 are symmetrically arranged around the center of the assembly axis 300.

[0049] In these optional embodiments, the assembly shaft 300 passes through the avoidance hole 230 along the first direction X and protrudes from the side of the second sub-portion 220 away from the first sub-portion 210, so that the sealing ring is assembled to the assembly shaft 300 and abuts against the second sub-portion 220. The second sub-portion 220 is rotatably connected to the sleeve body 100 through the first sub-portion 210. When the second sub-portion 220 deflects in a direction away from the assembly shaft 300, the second sub-portion 220 and the assembly shaft 300 are spaced apart to increase the diameter of the avoidance hole 230, so that part of the cooling pipe joint can be extended into the avoidance hole 230.

[0050] like Figure 3 and Figure 4 As shown, in some optional embodiments, at least two installation grooves 110 are provided at one end of the sleeve 100 facing the pressing block 200 , and the at least two installation grooves 110 are spaced apart around the assembly axis 300 , and the first section 210 of each pressing block 200 is respectively provided in each installation groove 110 .

[0051] Exemplarily, the number of the mounting slots 110 may be two or more, and the number of the mounting slots 110 may be the same as the number of the pressing blocks 200 , or the number of the mounting slots 110 may be greater than the number of the pressing blocks 200 .

[0052] In these optional embodiments, at least two installation grooves 110 are arranged at intervals around the assembly axis 300, so that when each pressing block 200 is installed in the installation groove 110 through the first sub-portion 210, each pressing block 200 is arranged around the assembly axis 300. The installation groove 110 is used to fix the circumferential position of the pressing block 200 on the assembly axis 300, so that the pressing block 200 can only move radially along the assembly axis 300.

[0053] like Figures 2 to 4 As shown, in some optional embodiments, each mounting groove 110 includes two side walls 120 spaced apart along the circumference of the sleeve body 100 ; each side wall 120 is provided with a mounting hole 130 , a rotating shaft 140 is arranged in the mounting hole 130 , and the first section 210 is rotatably connected to the rotating shaft 140 .

[0054] Exemplarily, the rotating shaft 140 may be fixedly connected to the mounting hole 130 , or the rotating shaft 140 may be fixed in the mounting hole 130 via a fixing member 150 .

[0055] In these optional embodiments, the first sub-portion 210 of the pressing block 200 is at least partially located between two spaced-apart side walls 120, each side wall 120 is provided with a mounting hole 130, and the end of the rotating shaft 140 is located in the mounting hole 130, so that the rotating shaft 140 is fixed to the mounting groove 110, and the first sub-portion 210 is rotatably connected to the rotating shaft 140 so that the pressing block 200 can rotate in a direction close to or away from the assembly axis 300. When the cooling pipe joint is pressed against each pressing block 200, the pressing block 200 will rotate in a direction away from the cooling pipe joint, and there is a gap between the pressing block 200 and the assembly axis 300 to allow the cooling pipe joint to be inserted into the avoidance hole 230.

[0056] Optional, such as Figure 3 As shown, the first section 210 is provided with a through hole 211 , and the rotating shaft 140 passes through the through hole 211 and the mounting hole 130 . Furthermore, the first section 210 includes two connecting plates 212 spaced apart along the circumference of the assembly axis 300 , and the through hole 211 is opened in the connecting plates 212 .

[0057] like Figure 3 and Figure 4 As shown, in some optional embodiments, the assembly mechanism is further provided with a fixing member 150, and the side wall 120 is further provided with a fixing hole 160 connected to the mounting hole 130, the fixing member 150 is arranged in the fixing hole 160, and part of the fixing member 150 extends to the mounting hole 130 to press against the fixed shaft 140.

[0058] In these optional embodiments, the fixing member 150 is disposed in the fixing hole 160, and the end of the fixing member 150 extends into the installation. The fixing member 150 presses the rotating shaft 140 to the inner wall of the installation hole 130 to fix the rotating shaft 140 and reduce the risk of the rotating shaft 140 falling off.

[0059] Optionally, the fixing member 150 includes a bolt, and an inner wall of the fixing hole 160 is provided with an internal thread. The fixing member 150 is screwed into the fixing hole 160 and extends into the mounting hole 130 to fix the rotating shaft 140 .

[0060] like Figure 1 , Figure 3 and Figure 5 As shown, in some optional embodiments, the assembly shaft 300 includes a first segment 310 and a second segment 320, the first segment 310 passes through the avoidance hole 230 and protrudes from the side of the second segment 220 away from the first segment 210, and the diameter of the second segment 320 is greater than the diameter of the first segment 310; the second segment 220 protrudes from the first segment 210 toward the avoidance hole 230, and the second segment 220 abuts against the second segment 320 on the side of the first segment 210 facing the first segment 210.

[0061] In these optional embodiments, the first section 310 is used to sleeve a sealing ring, the diameter of the second section 320 is larger than the diameter of the first section 310, the second section 220 protrudes from the first section 210 toward the avoidance hole 230, and the side of the second section 220 facing the first section 210 abuts against the second section 320, and the second section 320 is placed on the side of the second section 220 facing the first section 210, thereby reducing the risk of the assembly shaft 300 detaching from the avoidance hole 230.

[0062] Optional, such as Figure 1 and Figure 6 As shown, the sleeve body 100 is a cylindrical structure opened toward the second section 220 , and the second section 320 is located inside the sleeve body 100 .

[0063] like Figure 1 and Figure 3 As shown, in some optional embodiments, the first segment 310 includes a first sub-segment 311 and a second sub-segment 312 connected to each other along a first direction X, the second sub-segment 312 is connected to the second segment 320, the first sub-segment 311 is located on the side of the second sub-segment 312 away from the second segment 320, and the first sub-segment 311 is located on the side of the second section 220 away from the first section 210, and the diameter of the second sub-segment 312 is larger than that of the first sub-segment 311, so that the cooling pipe joint is sleeved on the first sub-segment 311 and abuts against the side of the second sub-segment 312 facing the first sub-segment 311.

[0064] In these optional embodiments, the diameter of the second sub-segment 312 is larger than that of the first sub-segment 311, so that the cooling pipe joint is sleeved on the first sub-segment 311 and abuts against the side of the second sub-segment 312 facing the first sub-segment 311, thereby fixing the relative position between the cooling pipe joint and the assembly axis 300. When the cooling pipe joint moves toward the sleeve body 100, the end of the cooling pipe joint presses against the assembly axis 300, reducing the risk of damage to the interior of the cooling pipe joint caused by the first sub-segment 311 extending too deeply into the interior of the cooling pipe joint.

[0065] like Figure 5 As shown, in some optional embodiments, the sealing ring assembly mechanism further includes an elastic ring 241 , and the elastic ring 241 is sleeved on the outer surface of the pressing block 200 on a side away from the avoidance hole 230 .

[0066] For example, the elastic ring 241 may be disposed on a side of the first sub-portion 210 away from the avoidance hole 230, or the elastic ring 241 may be disposed on a side of the second sub-portion 220 away from the avoidance hole 230. The material of the elastic ring 241 may include rubber material or the like.

[0067] In these optional embodiments, after the pressing block 200 moves in a direction away from the assembly axis 300, the elastic ring 241 applies a restoring force to each pressing block 200 in the direction of the assembly axis 300. After the cooling pipe joint is disengaged from the avoidance hole 230, the elastic ring 241 pushes the pressing block 200 to move in a direction close to the assembly axis 300 until the pressing block 200 abuts against the assembly axis 300, and each pressing block 200 returns to its initial position.

[0068] like Figure 1 As shown, in some optional embodiments, a groove 240 is provided on the side of the pressing block 200 away from the avoidance hole 230 , and an elastic ring 241 is sleeved on the side of each pressing block 200 away from the avoidance hole 230 and is located in the groove 240 .

[0069] Exemplarily, the groove 240 is disposed on a side of the first section 210 or the second section 220 away from the avoidance hole 230 .

[0070] In these optional embodiments, the groove 240 is circumferentially extended along the assembly axis 300 , and at least a portion of the elastic ring 241 is located in the groove 240 to fix the position of the elastic ring 241 and reduce the risk of the elastic ring 241 being detached.

[0071] like Figure 1 As shown, in some optional embodiments, the assembly shaft 300 is movably disposed along the first direction X.

[0072] In these optional embodiments, when the cooling pipe joint is sleeved on the assembly shaft 300, the cooling pipe joint can move along the first direction X synchronously with the assembly shaft 300, and the assembly shaft 300 guides the cooling pipe joint so that when the cooling pipe joint moves along the first direction X toward the sealing ring, the degree of deviation between the cooling pipe joint and the sealing ring is reduced, thereby improving the installation success rate.

[0073] like Figure 3 , Figure 5 and Figure 6 As shown, in some optional embodiments, the sealing ring assembly mechanism further includes a reset member 400 , which is disposed between the assembly shaft 300 and the sleeve body 100 , and is used to provide a reset force to the assembly shaft 300 away from the sleeve body 100 .

[0074] Exemplarily, the reset element 400 may include a spring or rubber.

[0075] In these optional embodiments, the reset member 400 is disposed on the side of the assembly axis 300 facing the sleeve body 100 along the first direction X, the sleeve body 100 has a bottom wall 180 facing away from the mounting groove 110, and the reset member 400 is located between the assembly axis 300 and the bottom wall 180. After the cooling pipe joint and the assembly axis 300 move close to the sleeve body 100 along the first direction X, the sealing ring is sleeved on the cooling pipe joint. When the cooling pipe joint is removed, the reset member 400 provides a reset force to the assembly axis 300 away from the sleeve body 100, so that the assembly axis 300 moves to the side of the second subsection 220 facing the first subsection 210 and abuts against the second segment 320, and the first segment 310 protrudes from the side of the second subsection 220 facing away from the first subsection 210, so as to install a sealing ring for the next cooling pipe joint.

[0076] like Figure 3 As shown, in some optional embodiments, the sleeve body 100 is provided with a limit member 500, which is arranged on the side of the assembly axis 300 along the first direction X toward the sleeve body 100, and the position of the limit member 500 along the first direction X is adjustable.

Optionally, the second segment 320 is located between the second subsection 220 and the stopper 500, and the movement range of the second segment 320 is located between the second subsection 220 and the stopper 500. The position of the limiter 500 along the first direction X can be adjusted to adjust the movable distance of the assembly axis 300 along the first direction X. When the cooling pipe joint is sleeved on the assembly axis 300 and moves close to the sleeve body 100 along the first direction X, the pressing block 200 presses the sealing ring and moves along the end of the cooling pipe joint away from the sleeve body 100. By adjusting the position of the limiter 500 along the first direction X to adjust the movable distance of the assembly axis 300 along the first direction X, the depth of the cooling pipe joint inserted into the avoidance hole 230 can be adjusted, so as to achieve the purpose of adjusting the position of the sealing ring sleeved on the cooling pipe joint to adapt to different installation positions of the sealing rings of different cooling pipe joints.
