Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle processing equipment technology, and in particular to airtight clamps for cooling pipes in new energy vehicles. Background Technology

[0002] With the continuous development of new energy vehicles globally and in my country, and given current social and environmental issues, the research and development of new energy vehicles is one of the effective solutions to alleviate energy and climate problems. For new energy vehicles, the drive motor is its core, and the demand for high-performance motors and high power density ratios is becoming increasingly strong. As the speed and power of drive motors in new energy vehicles increase, the demand for cooling also increases. Currently, the cooling of electric drive systems is mainly achieved through cooling oil pipes; therefore, the airtightness of the cooling oil pipes has become one of the important testing items for the efficient operation of the drive motor.

[0003] The cooling oil pipes for the drive motor mainly consist of a central longitudinal pipe, multiple transverse pipes, and a longitudinal tail pipe, such as... Figure 6 As shown, due to the crisscrossing structure, multiple cooling nozzles are located below the crisscrossing pipe body, increasing the difficulty of simultaneously and reliably sealing multiple cooling nozzles during airtightness testing. Currently, inspectors typically use multiple elastic rubber rings to seal and fix the pipe body with cooling nozzles before using airtightness testing equipment to test the airtightness of the drive motor cooling oil pipe. However, this method is prone to failure if the rubber rings are accidentally moved during testing, leading to misjudgments and a long setup time, significantly limiting testing efficiency. Therefore, how to efficiently achieve simultaneous and reliable sealing of multiple cooling nozzles, improving testing efficiency and reliability, is a crucial technical problem that needs to be solved in this case. Utility Model Content

[0004] To address the above problems, this utility model provides a compact, reliably sealed cooling nozzle clamp for new energy vehicles, which improves testing efficiency and reliability by providing a cooling pipe airtight clamp.

[0005] The technical solution of this utility model is:

[0006] Airtight clamps for cooling pipes in new energy vehicles include:

[0007] The support base has a limiting groove on the top that is compatible with the cooling oil pipe;

[0008] Several elastic sealing pads are provided and are fixedly installed in the limiting groove, corresponding to the cooling spray holes of the cooling oil pipe;

[0009] An intake linear drive mechanism is fixedly installed at the oil inlet of the cooling oil pipe. An intake column is provided at the piston rod end, and an intake hole connected to an air source is provided on the end face of the intake column.

[0010] A linear drive mechanism for blocking air is fixedly installed at the return port of the cooling oil pipe, and a second sealing column is fixedly connected to the piston rod end of the mechanism.

[0011] The clamping plate moves up and down above the support base via a clamping linear drive mechanism, and has several elastic pressure blocks at the bottom for pressing the cooling oil pipes.

[0012] Specifically, the top surface of the support base is provided with multiple fixedly connected limiting blocks.

[0018] The central longitudinal seat is detachably mounted on the top surface of the airtight workbench, located between the second transverse seat and the third transverse seat;

[0019] The tail longitudinal seat is detachably mounted on the top surface of the airtight workbench, located on the side of the fourth transverse seat.

[0020] Specifically, the side of the fourth transverse seat is provided with an installation slot that is adapted to the tail longitudinal seat.

[0021] Specifically, the top surface of the longitudinal seat at the tail is an inclined plane.

[0022] Specifically, the intake linear drive mechanism includes an intake cylinder, an intake hydraulic cylinder, or an intake electric push rod.

[0023] Specifically, the air-blocking linear drive mechanism includes an air-blocking cylinder, an air-blocking hydraulic cylinder, or an air-blocking electric push rod.

[0025] Specifically, the clamping plate slides up and down above the support base via a pair of guide posts.

[0026] Specifically, the elastic pressure block is detachably and fixedly mounted on the bottom surface of the pressure plate via a connector;

[0027] The clamping plate is provided with multiple fixedly connected crossbeams below it; the crossbeams are provided with several adjusting screws that are movably connected vertically.

[0028] The pressure plate is fixedly connected to the adjusting screw, and a spring A is provided between the pressure plate and the crossbeam.

[0029] This utility model includes a support base, elastic sealing pads, an air intake linear drive mechanism, an air blocking linear drive mechanism, and a pressing plate.

The second sealing post at the piston rod end of the air blocking linear drive mechanism seals the oil return port. While the air intake linear drive mechanism seals the area around the oil inlet, it also allows air to enter the cooling oil pipe through the air inlet hole and the hole in the middle of the first sealing ring. This efficiently achieves simultaneous and reliable sealing of multiple cooling nozzles, improving detection efficiency and reliability. Attached Figure Description

[0047] The following is for reference. Figure 1-7 Describe this utility model;

[0048] Airtight clamps for cooling pipes in new energy vehicles include:

[0049] The support base 210 has a limiting groove on the top that is adapted to the cooling oil pipe 100;

[0050] Specifically, the top surface of the support base 210 is provided with multiple limiting blocks 211 that are fixedly connected by connectors, such as... Figure 4 As shown, multiple limiting blocks 211 are positioned near the edge of their respective limiting grooves.

[0051] Support base 210 includes:

[0052] The first transverse seat 212 is detachably mounted on the top surface of the airtight workbench via a connector;

[0053] The second transverse seat 213 is detachably mounted on the top surface of the airtight workbench via a connector and is located on the side of the first transverse seat 212; in this case, the second transverse seat 213 is parallel to the first transverse seat 212.

[0054] The third transverse seat 214 is detachably mounted on the top surface of the airtight workbench via a connector, located on the side of the first transverse seat 212, and spaced apart from the second transverse seat 213; in this case, the third transverse seat 214 is parallel to the first transverse seat 212.

[0055] The fourth transverse seat 215 is detachably mounted on the top surface of the airtight workbench via a connector and is located on the side of the third transverse seat 214. In this case, the fourth transverse seat 215 is parallel to the first transverse seat 212. The side of the fourth transverse seat 215 is provided with a mounting slot that is adapted to the tail longitudinal seat 217. The end of the tail longitudinal seat 217 extends into the mounting slot, thereby improving assembly accuracy and efficiency.

[0056] The central longitudinal seat 216 is detachably mounted on the top surface of the airtight workbench via a connector, and is located between the second transverse seat 213 and the third transverse seat 214.

[0057] The tail longitudinal seat 217 is detachably mounted on the top surface of the airtight workbench via a connector, located on the side of the fourth transverse seat 215; in this case, the tail longitudinal seat 217 is parallel to the middle longitudinal seat 216. The top surface of the tail longitudinal seat 217 is inclined, adapted to the cooling oil pipe 100.

[0058] Several elastic sealing pads 220 are provided and are fixedly installed in the limiting groove, corresponding to the cooling nozzles of the cooling oil pipe 100. In this case, the elastic sealing pads 220 are rubber pads, and the cooling nozzles of the cooling oil pipe 100 are sealed by the corresponding elastic sealing pads 220.

[0059] The intake linear drive mechanism 230 is detachably and fixedly installed at the oil inlet of the cooling oil pipe 100 via a connector. Its piston rod end is provided with an intake column 231, and the end face of the intake column 231 is provided with an intake hole connected to an air source. The opening of the intake hole is provided with a first sealing ring 232 fixedly connected. The first sealing ring 232 is connected to the oil inlet of the cooling oil pipe 100 by extending the piston rod of the intake linear drive mechanism 230.

[0060] The intake linear drive mechanism 230 includes an intake cylinder, an intake hydraulic cylinder, or an intake electric push rod.

[0061] The air-blocking linear drive mechanism 240 is detachably and fixedly installed at the oil return port of the cooling oil pipe 100 via a connector. Its piston rod end is provided with a fixedly connected second sealing post 241, which is made of the same material as the sealing ring and is used to block the oil return port of the cooling oil pipe 100.

[0062] The air-blocking linear drive mechanism 240 includes an air-blocking cylinder, an air-blocking hydraulic cylinder, or an air-blocking electric push rod.

[0063] The clamping plate 250 moves up and down above the support base 210 via the clamping linear drive mechanism 251, and has several elastic pressure blocks 252 at the bottom for pressing the cooling oil pipe 100.

[0064] The clamping linear drive mechanism 251 includes a clamping cylinder, a clamping hydraulic cylinder, or a clamping electric push rod. The clamping plate 250 slides up and down above the support base 210 via a pair of guide posts.

[0065] After the cooling oil pipe 100 enters the limiting groove, the piston rod of the pressing linear drive mechanism 251 is pressed down, pressing multiple elastic pressure blocks 252 onto the upper surface of the cooling oil pipe 100. The multiple cooling nozzles of the cooling oil pipe 100 are sealed by corresponding elastic sealing pads 220. After the cooling oil pipe 100 is sealed and fixed, the air intake linear drive mechanism 230 and the air blocking linear drive mechanism 240 on both sides begin to operate. The second sealing post 241 at the piston rod end of the air blocking linear drive mechanism 240 seals the oil return port. While the air intake linear drive mechanism 230 seals the area around the oil inlet, it also allows air to enter the cooling oil pipe 100 through the air inlet hole and the central hole of the first sealing ring 232. This efficiently and reliably seals multiple cooling nozzles simultaneously, improving detection efficiency and reliability.

[0066] In this case, the elastic pressure block 252 is detachably and fixedly installed on the bottom surface of the pressure plate 253 via a connector;

[0067] Below the clamping plate 250, there are multiple fixedly connected crossbeams 254; the crossbeams 254 are provided with several vertically movable adjusting screws 2541.

[0068] The pressure plate 253 is adjustablely and fixedly connected to the adjusting screw 2541, and a spring A is provided between it and the crossbeam 254.

[0069] like Figure 2-3 As shown, during the pressing process of the linear drive mechanism 251, the elastic pressure block 252 is in pre-contact with the surface of the cooling oil pipe 100, and then overcomes the elastic force of the spring A, pressing the linear drive mechanism 251 continuously down to the set position and then stopping. The combination structure of multiple crossbeams and multiple pressure plates forms a multi-point support system for the cooling oil pipe 100, which, together with the elastic element spring A, can evenly distribute the load. The adjustable and fixed connection between the pressure plate 253 and the adjusting screw 2541 realizes the adjustable function of the spring A pressure, dynamically adjusting the clamping force according to the actual working conditions, avoiding damage to components due to excessive pressure, while the elastic buffering effect of spring A can effectively absorb impact loads. Further optimization, the support base 210 is provided with elastic buffer sleeves 260 on both sides, which are fixedly connected to the airtight worktable;

[0070] The buffer sleeve 260 has a buffer cavity with a top opening;

[0071] The buffer rod 261 is installed in the buffer cavity and moves up and down. The top of the buffer rod extends out from the top opening of the buffer sleeve through the buffer spring. The top opening limits the movement of the buffer rod 261 in the buffer cavity.

[0072] Below the clamping plate 250, there is a fixedly connected buffer column 262. By pressing down the buffer column 262, the buffer rod 261 is compressed into the buffer sleeve 260 for the first buffering. Then the elastic pressure block 252 contacts the cooling pipe for the second buffering, which effectively solves the problem of easy deformation of the cooling oil pipe 100 during inspection.
