Description

Technical Field

[0001] This invention relates to the field of new energy vehicle component technology, specifically a toughness testing device for new energy vehicle components. Background Technology

[0002] New energy vehicles are powered by new energy sources such as plug-in hybrid, pure electric, and fuel cell vehicles. The manufacturing process involves numerous components made of various materials. Sealing components, such as those in car doors, are commonly used. These sealing components are mostly rubber or composite material sealing strips. When testing the toughness of sealing strips, conventional tests such as tensile testing are usually performed, followed by static pressure testing for a certain period to measure resilience and other toughness data. Conventional door sealing strip tests often only perform compression tests on the sealing strip itself. However, during actual installation, the corners of car doors cause the sealing strip to bend and deform at these corners to conform to the door. This results in a difference between the actual installed sealing strip and the tested state. This difference may prevent the test data from accurately reflecting the sealing strip's performance in actual use, which is inconvenient. Summary of the Invention

[0010] Furthermore, the closed mechanism includes: The system consists of a fixed shell, two sealing plates, and an auxiliary cylinder. The fixed shell is located between two shells. Hydraulic cylinders are fixedly connected to both the top and bottom sides of the fixed shell, and the movable ends of the two hydraulic rods are fixedly connected to the two shells respectively. Two guide ports are opened on one side of the fixed shell, and the two sealing plates are slidably fitted into the two guide ports on the fixed shell. Threaded holes are opened on one side of each of the two sealing plates. The auxiliary cylinder is fixedly connected to the inner wall of the fixed shell, and a bidirectional screw is rotatably connected to the movable end of the auxiliary cylinder.

[0011] Furthermore, each fixed shell has a movable plate on one side, each movable plate has multiple sliding grooves on one side, each movable plate has two sliding plates slidably engaged on one side, each sliding plate has multiple protrusions fixedly connected to one side, each protrusion is slidably engaged inside an adjacent sliding groove, each sliding plate has an insertion hole on one side, each insertion hole is slidably engaged with an adjacent sealing plate, each fixed shell has multiple first cylinders fixedly connected inside, each first cylinder's movable end passes through an adjacent fixed shell and is fixedly connected to an adjacent movable plate, two sealing plates are provided between two movable plates, each sealing plate has slots at both ends, each movable plate has blocks fixedly connected to both ends, each movable plate is located at both ends of the same sealing plate, and the two blocks on each movable plate are slidably engaged with adjacent slots on the two sealing plates.

[0013] Furthermore, limit rollers are fixedly connected to both ends of the opening on one side of any housing, and any belt body passes over two adjacent limit rollers.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By applying static pressure to the sealing strip using two pressing mechanisms, and by adjusting the pressing mechanisms to create different bends on the pressing surface of the sealing strip, and ensuring that the bends on the pressing surface are at the same angles as the corners of the sealing strip during actual installation, the deformation of the sealing strip at the corners under pressure during actual installation can be detected. Furthermore, when the sealing strip is under static pressure, the pressing mechanism can work with the sealing mechanism to form two compartments with the sealing strip as the boundary. The sealing performance at the corners of the sealing strip can then be detected by checking whether there is air flow between the two compartments. Additionally, by adjusting the pressing mechanism in conjunction with the sealing mechanism, the sealing strip can be subjected to pressure at different points, and the temperature of the different pressure surfaces of the sealing strip can be adjusted to detect the degree of deformation of the sealing strip under temperature difference conditions. 2. Clamp both ends of the sealing strip with clamps, and then start the electric push rod to perform a routine tensile test on the sealing strip. When static pressure is required on the sealing strip, start the servo motor and main reducer to drive the adjacent take-up roller to rotate, so that the take-up roller can take up and unwind the adjacent strip. Start the linear guide to drive the adjacent connecting plate to move, and start multiple main cylinders to adjust the height of the two adjacent guide rollers. Then start the drive motor and auxiliary reducer to adjust the angle of the two adjacent guide rollers with bevel gears and helical gears, so that the two guide rollers can continuously bend the adjacent strip. The bent strip is located outside the housing. Then start the hydraulic cylinder to drive the two housings to move closer together, so that the bent parts of the two strips are brought closer together to perform static pressure on the sealing strip. The electric push rod can be started to pull the sealing strip, so that the part of the sealing strip between the two strips is in the same vertical plane and parallel to its own two ends. 3. During static pressure testing of the sealing strip, the distance between the two sealing plates inside the fixed housing is adjusted by rotating the bidirectional screw in advance, so that the sealing plates drive the adjacent sliding plates to move synchronously. By starting the main cylinder and the first cylinder, the two moving plates on the two fixed housings move towards each other, so that the sliding plates abut against the adjacent belts and the two sealing plates on the fixed housing are embedded in the adjacent belts. The two sealing plates inside the same belt are aligned and closed, so that any belt, the two adjacent sealing plates, the two adjacent sliding plates, and the two sealing plates form a closed space. Thus, the space between the two belts is divided into two compartments by the sealing strip. Then, gas is injected into one compartment, and the gas flow rate in the other compartment is detected to test the airtightness of the sealing strip. After static pressure testing is completed, the dimensions of the sealing strip are measured, and the rebound of the sealing strip is tested. 4. After the static pressure test of the sealing strip is completed, the two strips can be bent again so that the metal plate with high thermal insulation on the strip is close to the adjacent sealing plate, and the metal plate with high thermal conductivity on the strip is away from the adjacent sealing plate. This creates a closed space between the metal plate with high thermal conductivity on the strip and the adjacent sealing plate. Then, the metal plates of the two strips away from the adjacent sealing plate are used to apply static pressure to the sealing strip. Then, gas or liquid of different temperatures is injected into the different closed spaces formed between the metal plates with different thermal conductivity and the adjacent sealing plates. This creates a temperature difference between the two pressure surfaces of the sealing strip at the pressure point. After the static pressure is released, the rebound state of the sealing strip is tested to detect the toughness of the sealing strip when the temperature difference occurs.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-11 In this embodiment of the invention, a toughness testing device for new energy vehicle components includes: The system includes a base 100, two pressing mechanisms 300 for static pressure testing of the sealing strip, and two sealing mechanisms 400 for sealing the space on both sides of the sealing strip. The two pressing mechanisms 300 are located above the base 100 and are arranged vertically in sequence. Each pressing mechanism 300 includes a housing 310 with an opening on one side. A belt 320 is provided inside the housing 310, and the belt 320 includes multiple metal plates 321. Both ends of the housing 310 are rotatably connected to a take-up roller 330, and both ends of the belt 320 are fixedly wound with the two take-up rollers 330 respectively. The two sealing mechanisms 400 are located between the two pressing mechanisms 300.

[0019] Specifically, the belt body 320 is made of two different metal plates 321 interlaced together. One metal plate 321 has high thermal conductivity and can be made of materials such as aluminum, while the other metal plate 321 has poor thermal conductivity and can be made of materials such as heat-insulating aluminum alloy. Both metal plates 321 are made of relatively soft metal materials. During use, the metal plates 321 on the belt body 320 are freely bent to make the belt body 320 bend into different arc angles. The bending angle of each belt body 320 is the same as the angle of the corner of the door to be installed. Then, the door sealing strip is statically pressed by the belt body 320 on the two pressing mechanisms 300, so that the bending angle of the sealing strip at the static pressure point is the same as the angle of the actual installation state. This makes the state of the sealing strip under static pressure similar to the actual installation state. After the static pressure is completed, the resilience of the sealing strip is tested to determine the toughness of the sealing strip.

[0020] Example 1 like Figures 2-4 As shown, in this embodiment, multiple metal plates 321 on any belt body 320 are provided with multiple sleeve holes on one side, and a reinforcing rib 322 is fixedly connected inside each sleeve hole. Fixed plates 200 are fixedly connected to both ends of the base 100. Electric push rods 210 are fixedly connected to one side of each fixed plate 200. A clamp 220 is fixedly connected to the movable end of each electric push rod 210. Two motor boxes 331 are fixedly connected to both ends of any housing 310. A servo motor and a main reducer are provided inside each motor box 331. The motor shaft of each servo motor is fixedly connected to the input end of the adjacent main reducer, and the output end of each main reducer is fixedly connected to the adjacent take-up roller 330.

[0021] In this embodiment, the clamp 220 is prior art and will not be described in detail here. By using two clamps 220 to hold both ends of the sealing strip, when the sealing strip is not pressed by the belt body 320, the clamps 220 can be driven by activating two electric push rods 210 to stretch the sealing strip, thereby performing a stretch test on the sealing strip. Infrared sensors and other devices can be installed on the clamps 220 to detect data such as the stretch length of the sealing strip. The hardness of the reinforcing rib 322 is greater than that of the metal plate 321, so that the two metal plates 321 have internal reinforcing ribs 322. The support of 22 makes it less likely for the metal plate 321 to deform or dent when pressing against the sealing strip. The controller starts two servo motors, which drive the adjacent winding rollers 330 to rotate through the adjacent main reducers, thereby releasing or winding the adjacent belt 320, which is convenient for users. When using the bent belt 320 to apply static pressure to the sealing strip, the clamps 220 can be used to hold the two ends of the sealing strip to position it. Then, the electric push rod 210 is started to pull the sealing strip so that the part of the sealing strip between the two belts 320 is in the same vertical plane.

[0022] like Figures 2-5 As shown, in this embodiment, a linear guide rail 340 is fixedly connected inside any housing 310. Each linear guide rail 340 includes a slide table, and each slide table is fixedly connected to a plate 350. Multiple main cylinders 351 are fixedly connected to one side of each plate 350. A U-shaped plate 360 ​​is provided on one side of each plate 350. The movable end of each main cylinder 351 is fixedly connected to an adjacent U-shaped plate 360. Connecting plates 362 are rotatably connected to the two arms of each U-shaped plate 360 ​​via rotating shafts. Two guide rollers 363 are rotatably connected between the two connecting plates 362 on each U-shaped plate 360. The two guide rollers 363 on each U-shaped plate 360 ​​are located on adjacent belt bodies 32. On opposite sides of 0, a transmission rod 361 is rotatably connected between the two arms of any U-shaped plate 360. A drive box 370 is fixedly connected to one side of any U-shaped plate 360. A drive motor and an auxiliary reducer are installed inside any drive box 370. The motor shaft of any drive motor is fixedly connected to the input end of the adjacent auxiliary reducer. A bevel gear 302 is fixedly sleeved on the output end of any auxiliary reducer and any transmission rod 361. The two bevel gears 302 on any U-shaped plate 360 ​​mesh with each other. A helical gear 301 is fixedly sleeved on the outer wall of any rotating shaft and the outer wall of any transmission rod 361. The helical gear 301 on any rotating shaft meshes with the helical gear 301 on the adjacent transmission rod 361.

[0023] In specific implementation, the linear guide 340 is an existing technology that is electrically controlled, and will not be described in detail here. The controller starts the linear guide 340 to move the adjacent plate 350 and U-shaped plate 360. Then, the controller starts the drive motor, which drives the adjacent transmission rod 361 to rotate through the auxiliary reducer and the adjacent bevel gear 302. The transmission rod 361 then drives the two adjacent guide rollers 363 to rotate through the adjacent helical gear 301, so that the guide rollers 363 bend the adjacent belt 320. The controller starts multiple main cylinders 351, which can adjust the height of the adjacent U-shaped plate 360 ​​and guide rollers 363. The drive motor is started to release the belt 320. Then, by moving the position of the U-shaped plate 360 ​​and guide rollers 363, the belt 320 is bent at various points and the specific position of the belt 320 is adjusted. This facilitates automatic bending of the belt 320, adjustment of the bending angle of the belt 320, and adjustment of the specific position of the belt 320, making it convenient for users.

[0024] like Figures 6-11 As shown, in this embodiment, the closing mechanism 400 includes: The system comprises a fixed housing 410, two sealing plates 420, and an auxiliary cylinder 430. The fixed housing 410 is located between the two housings 310. Hydraulic cylinders are fixedly connected to both the top and bottom sides of the fixed housing 410, and the movable ends of the two hydraulic rods are fixedly connected to the two housings 310 respectively. Two guide ports are provided on one side of the fixed housing 410, and the two sealing plates 420 are slidably fitted into the two guide ports on the fixed housing 410. Threaded holes are provided on one side of each of the two sealing plates 420. The auxiliary cylinder 430 is fixedly connected to the inner wall of the fixed housing 410, and a bidirectional screw 431 is rotatably connected to the movable end of the auxiliary cylinder 430. The bidirectional screw 431 engages with the threaded holes on the two sealing plates 420. A movable plate 440 is provided on one side of each fixed housing 410, and multiple sliding grooves are provided on one side of each movable plate 440. Two sliding plates 441 are slidably engaged on one side of each movable plate 441, and multiple protrusions are fixedly connected to one side of each sliding plate 441. Each strip, any protruding strip, is slidably engaged with the interior of an adjacent groove. Each slide plate 441 has an insertion hole on one side, and each insertion hole is slidably engaged with an adjacent sealing plate 420. Each fixed shell 410 has multiple first cylinders 442 fixedly connected inside. The movable end of each first cylinder 442 passes through the adjacent fixed shell 410 and is fixedly connected with an adjacent moving plate 440. Two sealing plates 450 are provided between the two moving plates 440. Each sealing plate 450 has a slot at both ends. Each moving plate 440 has a block fixedly connected at both ends. Each moving plate 440 is located at both ends of the same sealing plate 450. The two blocks on each moving plate 440 are slidably engaged with the adjacent slots on the two sealing plates 450. Each sealing plate 450 has a through hole in the center for the sealing strip to pass through, and each sealing plate 450 has a test hole on one side. Each sealing plate 420 has multiple connecting pipe ports on one side.

[0025] In practice, when applying static pressure to the sealing strip, the sealing strip can be passed through the through holes on the two sealing plates 450, and then the two ends of the sealing strip can be clamped and fixed using the clamps 220. The auxiliary cylinder 430 is activated by the controller, which drives the two adjacent sealing plates 420 to move via the bidirectional screw 431. When adjusting the bending of the two belts 320, the sealing plates 420 are pulled into the adjacent fixed housings 410 by the adjacent auxiliary cylinders 430. The bidirectional screw 431 is a screw with both positive and negative threads; its rotation can drive the two adjacent sealing plates 410 to move. The two sealing plates 420 can move towards or away from each other. The distance between two adjacent sealing plates 420 can be adjusted by rotating the bidirectional screw 431. When the two belts 320 form a continuous bending state, the bending points of the two belts 320 protrude from the outside of the adjacent housings 310. The hydraulic cylinder is activated to drive the two housings 310 to move towards each other, thereby causing the housings 310 to drive the belts 320 to move towards each other to apply static pressure to the sealing strip. At the same time, the electric push rod 210 is used to pull the sealing strip, so that the sealing strip portion between the two belts 320 is in the same position. In a vertical plane, multiple first cylinders 442 are then simultaneously activated by the controller, causing the first cylinders 442 to drive two moving plates 440 to move towards each other, so that the sliding plates 441 on the moving plates 440 abut against the sides of the two belt bodies 320. At the same time, the auxiliary cylinder 430 is activated to drive the sealing plate 420 to move, so that the sealing plate 420 is embedded into the interior of the adjacent belt body 320 protruding from the adjacent housing 310, thereby aligning and abutting the two sealing plates 420 within the same belt body 320, so that any belt body 320 is in contact with the two sealing plates 410. 50. Two adjacent sliding plates 441 and two adjacent closing plates 420 form a closed space, and the statically pressed sealing strip can divide the space between the two belts 320 into two compartments. Then, gas is injected into one compartment through the test hole on the sealing plate 450, and the test hole connected to the other compartment is connected to a gas flow meter to detect whether there is gas flow in the other compartment, thereby detecting the sealing effect of the sealing strip. After the static pressure is completed, the dimensions of the sealing strip are measured to detect the rebound of the sealing strip. In this embodiment, after the inspection is completed, the belt 320 can be bent again so that both sides of the belt 320 are in contact with the adjacent slide plate 441, and the belt 320 is bent into a continuous wave shape. The metal plates 321 located on the two belts 320 and close to each other are metal plates 321 with high thermal conductivity. The metal plates 321 with high thermal insulation are in contact with and sealed with the adjacent sealing plate 420, so that the space between the metal plates 321 with high thermal conductivity on the belt 320 and the adjacent sealing plate 420 forms a closed space, and the metal plates 321 located on the two belts 320 and close to each other are bent. Fold the sealing strip to the installation angle and press it down by the two tape bodies 320 that are close to each other. Then, use the connecting pipe on the sealing plate 420 to inject gas or liquid at different temperatures into the different closed spaces formed by the sealing plate 420 and multiple thermally conductive metal plates 321. The temperature is transferred to the sealing strip through the thermally conductive metal plates 321, so that the two sides of the pressure surface of the sealing strip at the same pressure point have different temperatures. This allows the deformation of the sealing strip at multiple points under temperature difference to be tested. After the static pressure is released, the rebound state of the sealing strip is tested to detect the toughness of the sealing strip when temperature difference occurs.

[0026] like Figure 11 As shown, in this embodiment, the surfaces of the sealing plate 420, the sliding plate 441, the sealing plate 450, and the moving plate 440 are all covered with a rubber layer, so that when the plates are pressed together, they can be sealed by the rubber layer. The edge shape of the two sliding plates 441 on the same moving plate 440 can be designed specifically according to the corner angle of the belt body 320 during actual installation. For example, the edge shape of the two sliding plates 441 on the same moving plate 440 can be a wavy line, an irregular curved surface, etc. However, the two sliding plates 441 on the same moving plate 441 can fit together regardless of their shape.

[0027] Example 2 Based on Embodiment 1, the setting of the limiting roller 311 facilitates the limiting and guiding of the belt 320.

[0028] like Figures 2-3 As shown, in this embodiment, limit rollers 311 are fixedly connected to both ends of the opening on one side of any housing 310, and any belt 320 passes around two adjacent limit rollers 311.

[0029] In practice, by having the belt 320 pass around the limiting roller 311, the limiting roller 311 can be used to stroke the belt 320 when the winding roller 330 winds up the belt 320, thereby facilitating the winding of the belt 320 by the winding roller 330.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
