[0015] As a preferred embodiment of the present invention, a method for testing the static pressure strength of a cooler of a new energy vehicle comprises the following steps: Step 1: Place the cooler body into the positioning frame in a horizontal position; Step 2: Start the hydraulic push rod, which drives the push plate to slide horizontally. The swing arm at the end of the push plate drives the enclosure to move. The enclosure moves to the same horizontal line as the shield to protect the cooler body at the detection position. Step 3: During the sliding process of the push plate, the entire U-shaped frame and the positioning frame are driven to rotate by the rocker arm, and the T-shaped plate on the side wall of the positioning frame slides along the surface of the guide frame. When the T-shaped plate slides from the guide arc surface to the extrusion plane, the T-shaped plate slides toward the inlet of the positioning frame, and the T-shaped plate first squeezes the flip plate, and the flip plate drives the guide plate to rotate toward the center. The end of the guide plate is squeezed with the side wall of the cooler body, pushing the cooler body to the center position, until the flip plate slides to the side wall of the T-shaped plate. At this time, the T-shaped plate synchronously slides into the positioning groove, and the top of the T-shaped plate fits with the protrusion. As the T-shaped plate continues to slide, the T-shaped plate pushes the protrusion, the vertical rod and the lifting plate to lift, and finally lifts the cooler body, and the T-shaped plate slides along the positioning groove, thereby driving the adjusting roller with the positioning groove to rotate. At this time, the coaxially connected positioning plate rotates to the top of the cooler body, and the locking operation of the cooler body is completed by the lifting plate and the positioning plate; Step 4: When the interface of the cooler body is facing upward, the operator connects the input end of the water pressure static pressure test machine with one interface of the cooler body, and the other interface of the cooler body is connected with a pressure gauge, and then starts the cooler body to complete the static pressure detection operation; Step 5: After the test is completed, remove the pressure gauge and the input end of the water pressure static pressure testing machine, and then use the hydraulic push rod to drive the push plate to perform the reset operation until the positioning frame is in a horizontal state. At this time, continue to retract the push plate. At this time, the positioning frame rotates to an inclined state, so that the interface of the cooler body faces downward, which is convenient for the test water inside the cooler body to be discharged, and when the positioning frame continues to rotate, the T-shaped plate on the side wall of the positioning frame slides from the guide arc surface to the extrusion arc surface, thereby pushing the T-shaped plate to move, and then re-lock the cooler body through the process of step three to ensure that the cooler body will not separate from the positioning frame during the drainage process. When the drainage is completed, the positioning frame is rotated to a horizontal state, that is, the tested cooler body is taken out.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is conducting a test, the operator first starts the hydraulic push rod, which drives the push plate to slide horizontally, and the swing arm at the end of the push plate drives the enclosure to move, and the enclosure moves to the same horizontal line as the shielding plate, thereby protecting the cooler body located at the test position, so that even if the cooler body is damaged during the test, the water inside the cooler body will not disperse, and the electronic components of the test equipment can be protected, making the test safer.

[0017] The T-shaped plate is pressed against the guide plate to move upward, and the guide plate is pressed against the guide plate to move upward, so that the guide plate is pressed against the guide plate and the guide plate moves upward.

[0018] After the detection process of the present invention is completed, the push plate is driven by the hydraulic push rod to perform a reset operation until the positioning frame is in a horizontal state. At this time, the push plate continues to retract. At this time, the positioning frame rotates to an inclined state, so that the interface of the cooler body faces downward, which is convenient for the test water inside the cooler body to be discharged, reducing the weight of the cooler body, making it convenient for later operators to disassemble and assemble the cooler body, and improving the efficiency of disassembly and assembly.

When the T-shaped plate 202 moves up, the top of the T-shaped plate 202 is fitted with the protrusion 2055. As the T-shaped plate 202 continues to slide, the T-shaped plate 202 pushes the protrusion 2055, the vertical rod 2052 and the lifting plate 205 to lift, and finally lifts the cooler body 400, wherein the side rod 2053 on the surface of the protrusion 2055 slides in the displacement groove 2054, which serves the purpose of limiting.

The synchronous shaft 2062 movably penetrates the U-shaped frame 107, and the end of the synchronous shaft 2062 is connected to the rotation center of the positioning plate 206. When the T-shaped plate 202 slides along the positioning groove 2032, it drives the adjusting roller 203 with the positioning groove 2032 to rotate, and at this time, the positioning plate 206 can be driven to rotate to the top of the cooler body 400 through the synchronous shaft 2062.

[0036] Embodiment 3: The present invention also discloses a testing method for a static pressure strength testing device for a cooler of a new energy vehicle, the steps of which are as follows: Step 1: Place the cooler body 400 into the positioning frame 108 in a horizontal position; Step 2: Start the hydraulic push rod 104, the hydraulic push rod 104 drives the push plate 1041 to slide horizontally, the swing arm 1042 at the end of the push plate 1041 drives the enclosure 102 to move, and the enclosure 102 moves to the same horizontal line as the shielding plate 1021 to protect the cooler body 400 located at the detection position; Step 3: During the sliding process of the push plate 1041, the entire U-shaped frame 107 and the positioning frame 108 are driven to rotate through the rocker arm 1061, and the T-shaped plate 202 on the side wall of the positioning frame 108 slides along the surface of the guide frame 201. When the T-shaped plate 202 slides from the guide arc surface 2011 to the extrusion plane 2012, the T-shaped plate 202 slides toward the entrance of the positioning frame 108, and the T-shaped plate 202 first squeezes the flip plate 2045, and the flip plate 2045 drives the guide plate 204 to rotate toward the center, and the end of the guide plate 204 squeezes the side wall of the cooler body 400, pushing the cooler body 400 to the center until the flip plate 204 After sliding to the side wall of the T-shaped plate 202, the T-shaped plate 202 synchronously slides into the positioning groove 2032, and the top of the T-shaped plate 202 fits with the protrusion 2055. As the T-shaped plate 202 continues to slide, the T-shaped plate 202 pushes the protrusion 2055, the vertical rod 2052 and the lifting plate 205 to lift up, and finally lifts the cooler body 400, and the T-shaped plate 202 slides along the positioning groove 2032, thereby driving the adjustment roller 203 with the positioning groove 2032 to rotate, and at this time, the coaxially connected positioning plate 206 rotates to the top of the cooler body 400, and the locking operation of the cooler body 400 is completed through the lifting plate 205 and the positioning plate 206; Step 4: When the interface of the cooler body 400 is facing upward, the operator connects the input end of the hydrostatic tester 300 with one interface of the cooler body 400, and the other interface of the cooler body 400 is connected with a pressure gauge 401, and then starts the cooler body 400 to complete the static pressure detection operation; Step 5: After the test is completed, remove the pressure gauge 401 and the input end of the water pressure static pressure testing machine 300, and then use the hydraulic push rod 104 to drive the push plate 1041 to perform a reset operation until the positioning frame 108 is in a horizontal state. At this time, continue to let the push plate 1041 retract. At this time, the positioning frame 108 rotates to an inclined state, so that the interface of the cooler body faces downward, which is convenient for the test water inside the cooler body 400 to be discharged, and when the positioning frame 108 continues to rotate, the T-shaped plate 202 on the side wall of the positioning frame 108 slides from the guide arc surface 2011 to the extrusion arc surface 2014, thereby pushing the T-shaped plate 202 to move, and then re-locking the cooler body 400 through the process of step three to ensure that the cooler body 400 will not separate from the positioning frame 108 during the drainage process. When the drainage is completed, the positioning frame 108 is rotated to a horizontal state, that is, the tested cooler body 400 is taken out.

[0037] The implementation principle of the static pressure strength testing device and method of the cooler of a new energy vehicle of the present invention is as follows: The operator first needs to place the cooler body 400 into the positioning frame 108 in a horizontal position, and then the operator needs to start the hydraulic push rod 104. The hydraulic push rod 104 drives the push plate 1041 to slide horizontally. The swing arm 1042 at the end of the push plate 1041 drives the enclosure 102 to move. The enclosure 102 moves to the same horizontal line as the shield 1021 to protect the cooler body 400 at the detection position.

[0038] During the sliding of the push plate 1041, the slide rod 1062 of the rocker arm 1061 slides on the strip groove 1063 of the push plate 1041, thereby driving the rocker arm 1061 to rotate. At this time, the rocker arm 1061 synchronously rotates with the rotation shaft 1071 to drive the U-shaped frame 107 to rotate, and the U-shaped frame 107 can drive the overall positioning frame 108 to rotate, and finally the cooler body 400 inside the positioning frame 108 can be rotated to a vertical state.

[0039] When the positioning frame 108 rotates, the T-shaped plate 202 on the side wall of the positioning frame 108 rotates synchronously, and the synchronization plate 2021 and the mounting frame 2022 at the end of the T-shaped plate 202 slide synchronously. The guide wheel 2023 on the mounting frame 2022 can slide along the surface of the guide frame 201, and then the guide wheel 2023 can slide along the guide arc surface 2011 to the extrusion plane 2012. In this process, the T-shaped plate 202 slides as a whole toward the entrance of the positioning frame 108.

[0040] When the T-shaped plate 202 slides, the slide plate 2024 on the side wall of the T-shaped plate 202 can slide on the positioning rod 2025, and the distance between the slide plate 2024 and the positioning seat 2026 becomes closer, so that the positioning spring 2027 can be compressed, and the compressed positioning spring 2027 is convenient for later resetting.

[0041] When the T-shaped plate 202 slides, the T-shaped plate 202 will first squeeze the flip plate 2045. At this time, the flip plate 2045 and the clamping shaft 2043 rotate inside the installation groove 2041, and the guide plate 204 on the clamping shaft 2043 rotates toward the side wall of the cooler body 400, which will eventually make the end of the guide plate 204 squeeze the side wall of the cooler body 400, pushing the cooler body 400 to move toward the center, achieving the purpose of preliminary guidance. As the T-shaped plate 202 slides, the flip plate 2045 will eventually slide to the side wall of the T-shaped plate 202, and the subsequent movement of the T-shaped plate 202 will not drive the flip plate 2045 to move.

[0042] During the above-mentioned operation, the slider 2033 on the side wall of the T-shaped plate 202 slides into the positioning groove 2032 along the vertical guide groove 2031, and at this time, the top of the T-shaped plate 202 is in contact with the protrusion 2055. As the T-shaped plate 202 continues to slide, the T-shaped plate 202 pushes the protrusion 2055, the vertical rod 2052 and the lifting plate 205 to lift, and finally lifts the cooler body 400, and the T-shaped plate 202 will subsequently slide along the positioning groove 2032, thereby driving the adjustment roller 203 with the positioning groove 2032 to rotate. At this time, the positioning plate 206 can be driven to rotate above the cooler body 400 through the synchronous shaft 2062. The lifting plate 205 and the positioning plate 206 cooperate with each other to complete the locking operation of the cooler body 400. At this time, it is more convenient to install the water pressure static pressure testing machine 300 and the cooler body 400, and the detection efficiency is further improved.

[0043] When locking is completed, the interface of the cooler body 400 is facing upward, and the operator connects the input end of the water pressure static pressure testing machine 300 with an interface of the cooler body 400. The other interface of the cooler body 400 is connected to the pressure gauge 401. Then the cooler body 400 is started to complete the static pressure detection operation. After the detection is completed, the operator needs to disassemble the water pressure static pressure testing machine 300 and the pressure gauge 401.

[0044] Then the operator drives the push plate 1041 to perform a reset operation through the hydraulic push rod 104 until the positioning frame 108 is in a horizontal state, that is, restored to the Figure 2Initial state, when the push plate 1041 continues to retract, the positioning frame 108 rotates to an inclined state, so that the interface of the cooler body 400 faces downward, which is convenient for the test water inside the cooler body 400 to be discharged, reduces the weight of the cooler body, and facilitates the later operators to disassemble and assemble the cooler body, thereby improving the efficiency of disassembly and assembly, and when the positioning frame 108 continues to rotate, the T-shaped plate 202, the synchronous plate 2021 and the guide wheel 2023 on the side wall of the positioning frame 108 slide from the guide arc surface 2011 to the extrusion arc surface 2014. In this process, the T-shaped plate 202 slides as a whole toward the entrance of the positioning frame 108, thereby repeating the above operation, and finally the cooler body 400 can be locked to ensure that the cooler body 400 will not separate from the positioning frame 108 during the drainage process. When the drainage is completed, the positioning frame 108 is rotated to a horizontal state, that is, the cooler body 400 that has been tested is taken out.
