Liquid cooling pipe positioning tool

Abstract

The utility model provides a liquid cooling pipe positioning tool, which relates to the technical field of battery packs and comprises a positioning seat and a positioning component. When the liquid cooling pipe is installed, the positioning assembly moves in the first direction, gets close to the bottom shell and is matched and positioned with the water nozzle, so that the water nozzle is kept static relative to the fixing hole, and the water nozzle is prevented from being scratched with the hole wall in the process of installing the liquid cooling pipe. And after the liquid cooling pipe is installed, the liquid cooling pipe is fixed, and the water nozzle is correspondingly fixed and still keeps static relative to the fixing hole. And at the moment, the positioning assembly reversely moves in the first direction, is far away from the bottom shell and is separated from the water nozzle, so that the module-free battery pack enters the next assembly process. Based on the arrangement, the water nozzle of the liquid cooling pipe is ensured to be still relative to the bottom shell all the time before and after the liquid cooling pipe is installed, scraping collision between the water nozzle and the bottom shell is avoided, and the risk of liquid leakage of the cooling liquid caused by serious scraping is further avoided.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] As mentioned in the background technology, during the assembly process of the liquid cooling pipe of the module-free battery, the nozzle of the liquid cooling pipe that passes through the fixed hole opened in the bottom shell is unstable and often easily scratches the hole wall, causing itself to be damaged. In particular, if the nozzle is severely damaged, there will be a risk of leakage of the coolant in the battery pack.

[0032] In view of the above problems, the utility model provides a liquid cooling tube positioning tool 10, which can position the positioning component 300 and the water nozzle 51 so that the water nozzle 51 maintains a fixed position relative to the bottom shell 30, thereby avoiding scratches between the water nozzle 51 and the bottom shell 30, and correspondingly avoiding leakage of coolant due to damage of the water nozzle 51.

[0033] Figure 1 This is a working schematic diagram of the liquid cooling tube positioning tool 10 provided in an embodiment of the utility model. Figure 2 The embodiment of the utility model provides Figure 1 The enlarged schematic diagram of point A in the middle, Figure 3 For a schematic diagram of the liquid cooling tube positioning tool 10 provided in the embodiment of the utility model, please refer to Figures 1 to 3The utility model provides a liquid cooling tube positioning tool 10, which includes a positioning seat 100 and a positioning assembly 300.

[0034] The positioning assembly 300 is slidably connected to the positioning seat 100 along the first direction 910 to move closer to or farther from the bottom shell 30 and to cooperate with or disengage from the water nozzle 51 passing through the bottom shell 30 so that the water nozzle 51 remains stationary relative to the bottom shell 30 .

[0035] It can be understood that, in the present embodiment, the water nozzle 51 specifically refers to the liquid inlet nozzle 51 and / or the liquid outlet nozzle 51 of the liquid cooling tube 50 , and the above-mentioned water nozzles 51 respectively pass through the corresponding fixing holes 31 opened in the bottom shell 30 .

[0036] Specifically, when installing the liquid cooling tube 50, the positioning assembly 300 moves along the first direction 910, approaches the bottom shell 30, and cooperates with the water nozzle 51 for positioning, so that the water nozzle 51 remains stationary relative to the fixing hole 31, thereby avoiding the water nozzle 51 from scratching the hole wall during the installation of the liquid cooling tube 50.

[0037] After the liquid cooling tube 50 is installed, the liquid cooling tube 50 is fixed, and the water nozzle 51 is also fixed accordingly, and remains relatively still with respect to the fixing hole 31. At this time, the positioning assembly 300 moves in the opposite direction along the first direction 910, away from the bottom shell 30, and disengages from the water nozzle 51, so that the module-free battery pack enters the next assembly process.

[0038] Based on the above arrangement, it is ensured that the water nozzle 51 of the liquid cooling tube 50 is always stationary relative to the bottom shell 30 before and after the installation of the liquid cooling tube 50, thereby avoiding scratches and collisions between the two, and further avoiding the risk of coolant leakage due to severe scratches.

[0039] like Figure 1 and Figure 2 As shown, when applied in actual scenarios, the liquid cooling tube positioning tool 10 and the bottom shell 30 need to be placed on the welding turnover vehicle 70 to facilitate the installation of the liquid cooling tube 50. Figure 3 As shown, in order to prevent the liquid cooling tube positioning tool 10 from moving relative to the welding trolley 70 , the liquid cooling tube positioning tool 10 also includes a fixing assembly 700 , which is connected to the positioning seat 100 and is used to be fixed to the welding trolley 70 .

[0040] In some embodiments, such as Figure 3As shown, the fixing assembly 700 includes a first fixing plate 710, a second fixing plate 730 and a plurality of positioning pins 750, and the first fixing plate 710 and the second fixing plate 730 are respectively connected to the two sides of the positioning seat 100, and are both fixed to the welding trolley 70 through the positioning pins 750, thereby ensuring that the positioning seat 100 and the positioning assembly 300 are fixed relative to the welding trolley 70, thereby ensuring that the water nozzle 51 and the positioning assembly 300 will not be offset or bumped when they are matched.

[0041] In addition, it should be noted that after the liquid cooling tube 50 on the welding trolley 70 is installed, the liquid cooling tube positioning tool 10 of the present application can be removed by disassembling the positioning pin 750 and moved to another welding trolley 70 for repeated operations.

[0042] See also Figure 4 , Figure 4 A partial schematic diagram of the liquid cooling tube positioning tool 10 provided in an embodiment of the utility model. In some embodiments, the positioning seat 100 is provided with a slide rail 130 extending along the first direction 910, and the positioning assembly 300 includes a positioning rod 310 for cooperating with the inner wall of the water nozzle 51, and the end of the positioning rod 310 away from the water nozzle 51 is slidably matched with the slide rail 130. In other embodiments, the positioning rod 310 can also be replaced with a positioning sleeve that cooperates with the outer wall of the water nozzle 51, which will not be repeated here.

[0043] like Figure 2 As shown, the positioning rod 310 is moved along the first direction 910 to be inserted into the water spout 51, and the two are concentrically limited. At this time, under the support of the positioning rod 310, the water spout 51 is located in the fixing hole 31 and remains stationary relative to the hole wall of the fixing hole 31. Based on this, the water spout 51 is prevented from scratching against the hole wall, and the structural strength and safety of the water spout 51 are ensured.

[0044] It should be noted that, as shown in Figure 4, the positioning seat 100 may include two positioning plates 150 of the same shape, both of which are provided with grooves. The two positioning plates 150 are aligned and fixed by screws to form the above-mentioned slide groove 110; or the positioning seat 100 includes only one positioning plate 150, and the above-mentioned slide groove 110 is formed by stamping or injection molding. In addition, it should be noted that in order to further enhance the protection of the water nozzle 51, the central axes of the positioning rod 310, the fixing hole 31 and the water nozzle 51 are all located on the same straight line.

[0045] In order to improve the smoothness and comfort of the positioning rod 310 when cooperating with the water nozzle 51, the positioning assembly 300 also includes a first elastic member 330, one end of the first elastic member 330 is connected to the end of the slide rail 130 away from the water nozzle 51, and the other end is connected to the positioning rod 310.

[0046] Similar to the above, the central axes of the slide groove 110, the first elastic member 330 and the positioning rod 310 can also be located on the same axis, so that the first elastic member 330 pushes the positioning rod 310 along the axial direction of the positioning rod 310 to move along the first direction 910, thereby reducing the error of manual adjustment and improving the accuracy of positioning.

[0047] Considering that the liquid cooling tube 50 generally includes a liquid inlet nozzle 51 and a liquid outlet nozzle 51, accordingly, the number of the positioning rods 310 is two, and the two positioning rods 310 are spaced apart along a second direction 930 perpendicular to the first direction 910, and one of the positioning rods 310 is used to cooperate with the liquid inlet nozzle 51, and the other positioning rod 310 is used to cooperate with the liquid outlet nozzle 51, so as to support and position the liquid inlet nozzle 51 and the liquid outlet nozzle 51 respectively.

[0048] It is understandable that if Figure 4 As shown, the number and position of the fixing holes 31 provided in the positioning rod 310, the first elastic member 330, the slide rail 130 and the bottom shell 30 in the liquid cooling tube positioning fixture 10 and the water nozzle 51 of the liquid cooling tube 50 are in a one-to-one correspondence. In addition, the positioning rods 310 and the positioning rods 310 can slide independently along the first direction 910, or can slide synchronously along the first direction 910.

[0049] In some embodiments, the liquid cooling tube positioning tool 10 further includes a sliding assembly 500 , and the sliding assembly 500 is slidably connected to the positioning seat 100 and connected to the positioning assembly 300 , so as to drive the positioning assembly 300 to slide back and forth along the first direction 910 .

[0050] It should be noted that the sliding assembly 500, as a force-applying assembly, can provide the external force required for the reciprocating sliding of the positioning assembly 300. For example, when moving in the reverse direction along the first direction 910, the reaction force of the first elastic member 330 needs to be overcome; for example, when moving along the first direction 910, the moving speed of the positioning assembly 300 is buffered or adjusted.

[0051] In detail, the positioning seat 100 is provided with a slide groove 110 extending along the first direction 910 , and the sliding assembly 500 includes a sliding member 510 cooperating with the slide groove 110 and a connecting member 530 connected to the positioning assembly 300 , and the connecting member 530 is provided with a positioning hole cooperating with the sliding member 510 .

[0052] Based on the above configuration, it can be learned that the connecting member 530 is connected to the positioning assembly 300 and the sliding member 510 at the same time, and is specifically connected to the positioning rod 310 and the sliding member 510 at the same time. Figure 4As shown, when there are two positioning rods 310, the two ends of the connecting member 530 can be connected to the two positioning rods 310 respectively, and a positioning hole cooperating with the sliding member 510 is opened in the middle to facilitate the synchronous movement of the two positioning rods 310 and the sliding member 510, thereby increasing the positioning efficiency.

[0053] On the basis of the above, since the slide groove 110 cooperating with the sliding member 510 and the slide rail 130 cooperating with the positioning rod 310 both extend along the first direction 910, the repeated positioning of the two is conducive to ensuring that the first positioning rod 310 always moves back and forth along the first direction 910, avoiding its deviation and affecting the positioning efficiency with the water nozzle 51.

[0054] like Figure 5 As shown, in order to ensure that the sliding member 510 slides along the first direction 910 on the horizontal plane, the sliding member 510 includes a first step portion 511 and a second step portion 513 arranged along a third direction 950 perpendicular to the first direction 910; the first step portion 511 passes through the positioning hole and the slide groove 110 in sequence along the first direction 910, and a first abutting surface 512 that abuts against the groove edge of the slide groove 110 is formed between the second step portion 513 and the first step portion 511.

[0055] It can be understood that when the sliding member 510 is at the slide groove 110 extending along the first direction 910, the first step portion 511 is located inside the slide groove 110, the second step portion 513 is located outside the slide groove 110, and the first abutting surface 512 between the first step portion 511 and the second step portion 513 abuts against the groove edge of the slide groove 110. When reciprocating along the first direction 910, the first abutting surface 512 is horizontally fitted with the groove edge, thereby ensuring that the sliding member 510 reciprocates along the first direction 910 on a horizontal plane. In addition, it can also be understood that the first direction 910, the second direction 930 and the third direction 950 are perpendicular to each other.

[0056] In order to facilitate the positioning rod 310 that is disengaged from the water nozzle 51 to be limited to the initial position after the liquid cooling tube 50 is assembled, the positioning seat 100 is also provided with a positioning groove 120 connected to the end of the slide groove 110 away from the water nozzle 51, and the sliding member 510 also includes a third step portion 515 connected to the second step portion 513 along the third direction 950; the second step portion 513 cooperates with the positioning groove 120, and a second abutting surface 514 is formed between the second step portion 513 and the third step portion 515 to abut against the groove edge of the positioning groove 120.

[0057] Based on the above configuration, it can be understood that the sliding member 510 includes a first step portion 511, a second step portion 513, and a third step portion 515 whose diameters are successively increased along the third direction 950. Also, similar to the above, when the sliding member 510 moves to the positioning groove 120, the second step portion 513 is located inside the positioning groove 120, the third step portion 515 is located outside the positioning groove 120, and the second abutting surface 514 between the second step portion 513 and the third step portion 515 abuts against the groove edge of the positioning groove 120.

[0058] In other words, when the sliding member 510 moves to the farthest point from the water spout 51 (i.e., the positioning groove 120), it moves in the opposite direction (i.e., lifts upward) along the third direction 950 until the second abutting surface 514 abuts against the groove edge of the positioning groove 120. Since the diameter of the second step portion 513 is greater than the width of the slide groove 110, the sliding member 510 is limited in the positioning groove 120 and will not be moved again along the first direction 910 by the abutment of the first elastic member 330.

[0059] Accordingly, in order to ensure that the sliding member 510 can be effectively locked by mechanical components when it is located at the sliding groove 110 or the positioning groove 120, thereby preventing the sliding member 510 from falling off due to gravity due to human operating errors, the sliding assembly 500 also includes a limit member 590 threadedly connected to the first step portion 511.

[0060] Specifically, when the sliding member 510 is located at the slide groove 110, the limiting member 590 is adjusted to cooperate with the first abutting surface 512, so that the first step portion 511 slides smoothly or is locked relative to the slide groove 110. When the sliding member 510 is located at the positioning groove 120, the limiting member 590 is adjusted again to cooperate with the second abutting surface 514, so that the second step portion 513 is locked relative to the positioning groove 120.

[0061] In order to further reduce labor costs, the sliding assembly 500 further includes a second elastic member 570 sleeved on the first step 511, and the two ends of the second elastic member 570 are respectively connected to the stopper 590 and the connecting member 530. When the sliding member 510 is located at the slide groove 110, the stopper 590 located at the fixed position and the first abutting surface 512 act together, and the second elastic member 570 is stretched; when the sliding member 510 is located at the positioning groove 120, the first abutting surface 512 fails, and the stopper 590 moves in the opposite direction along the third direction 950 under the action of the second elastic member 570, and at the same time drives the sliding member 510 to move in the opposite direction along the third direction 950 until the second step 513 cooperates with the positioning groove 120, and the second abutting surface 514 acts together with the stopper 590.

[0062] Taking the liquid cooling tube positioning tool 10 provided in this embodiment as an example, its working process and working principle are as follows:

[0063] The operator first fixes the shell and the liquid cooling tube positioning tool 10 on the welding trolley 70. Specifically, the first fixing plate 710 and the second fixing plate 730 connected to the two sides of the positioning seat 100 are fixed to the welding trolley 70 through the positioning pins 750, and ensure that the fixing hole 31 opened in the shell is coaxially arranged with the positioning rod 310.

[0064] When installing the liquid cooling tube 50, the operator presses down the stopper 590, so that the sliding member 510 moves from the positioning groove 120 to the sliding groove 110. Under the action of the first elastic member 330, the positioning rod 310 moves along the first direction 910 and is inserted into the water nozzle 51 of the liquid cooling tube 50, and the two are concentrically limited. At this time, under the support of the positioning rod 310, the water nozzle 51 is located in the fixing hole 31 and remains stationary relative to the hole wall of the fixing hole 31.

[0065] After the liquid cooling tube 50 is installed, the operator pushes the connecting member 530 to overcome the elastic force of the first elastic member 330, and drives the positioning rod 310 to move in the opposite direction along the first direction 910. When the sliding member 510 is reset to the positioning groove 120, the limiting member 590 moves in the opposite direction along the third direction 950 under the action of the second elastic member 570, and drives the sliding member 510 to move in the opposite direction along the third direction 950 until the second step 513 is matched with the positioning groove 120. At this time, the positioning rod 310 is disengaged from the water nozzle 51 and is limited and fixed to the initial position.

[0066] When the above actions are completed, the operator can remove the liquid cooling tube positioning tool 10 of the present application by disassembling the positioning pin 750, and move it to another welding turnover vehicle 70 to repeat the operation.

[0067] In summary, the utility model provides a liquid cooling tube positioning tool 10, which includes a positioning seat 100 and a positioning assembly 300. When installing the liquid cooling tube 50, the positioning assembly 300 moves along the first direction 910, approaches the bottom shell 30, and cooperates with the water nozzle 51 to position, so that the water nozzle 51 remains stationary relative to the fixing hole 31, avoiding the water nozzle 51 from scratching the hole wall during the installation of the liquid cooling tube 50. After the liquid cooling tube 50 is installed, the liquid cooling tube 50 is fixed, and the water nozzle 51 is also fixed accordingly, and still remains relatively stationary with the fixing hole 31. At this time, the positioning assembly 300 moves in the opposite direction along the first direction 910, away from the bottom shell 30, and disengages from the water nozzle 51, so that the module-free battery pack enters the next assembly process. Based on the above arrangement, it is ensured that before and after the installation of the liquid cooling tube 50, the water nozzle 51 of the liquid cooling tube 50 is always stationary relative to the bottom shell 30, avoiding scratches and collisions between the two, and further avoiding the risk of leakage of the coolant due to severe scratches.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
