Description

Technical Field

[0001] This utility model belongs to the field of charger pressure resistance testing technology, specifically relating to a car charger pressure resistance testing device. Background Technology

[0002] With the rapid development of the electric vehicle industry, the safety and reliability of car chargers have become an increasingly important focus for consumers and manufacturers. In order to ensure that car chargers can withstand various pressures and loads that may be encountered in actual use, pressure testing has become an indispensable part of the charger production process. Traditional car charger pressure testing devices usually use a fixed test bench with a cylinder-driven pressure block to simulate external force compression in order to evaluate the structural strength and durability of the charger. For example, the existing patent with publication number CN205958251U discloses "an electric vehicle charging pile crushing test machine, including a frame, the inner bottom surface of the frame is provided with a working platform, the surface of the working platform is provided with a fixed block and a groove, the inner bottom surface of the groove is provided with a sliding block and a screw, and the two ends of the screw pass through the surface of the sliding block and the surface of the working platform respectively". It can be seen that the application describes a common car charger pressure testing device. In the test process, the charger is placed on a fixed test bench and fixed by clamps on both sides to ensure that the charger does not move during the test. Then, the cylinder drives the pressure block to move down in the vertical direction to apply a preset pressure to the charger to detect its deformation and structural integrity under pressure.

[0003] However, in practical use, the existing pressure resistance testing device has a fixed test platform that cannot rotate. If it is necessary to test other areas of the charger besides the initial placement position, the operator must first stop the current test, manually release the clamps on both sides of the charger, readjust the position of the charger, and finally clamp and limit it again through the clamps on both sides before testing other parts of the charger. The whole process is time-consuming and laborious, and the frequent clamping may increase the risk of damage to the charger during the adjustment process, which is not conducive to improving testing efficiency and protecting the tested sample. Therefore, this utility model proposes a pressure resistance testing device for automobile chargers. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides a technical solution: a car charger pressure resistance testing device, comprising...

[0026] The base 1 has a U-shaped frame 2 at the top, a cylinder 3 installed on the inner side of the top of the U-shaped frame 2, a lifting platform 4 slidably installed on the inner side of the U-shaped frame 2 and connected to the free end of the cylinder 3, and a compression test head 5 installed at the bottom of the lifting platform 4. In actual testing, the car charger 7 is placed on the top of the rotary test platform 6 and clamped and limited by two clamping assemblies 8. Then the cylinder 3 is activated, so that the lifting platform 4 moves down with the compression test head 5, causing the compression test head 5 to compress the surface of the car charger 7, so that the car charger 7 can be subjected to a conventional compressive strength test.

[0027] The rotating test platform 6 is mounted on the top surface of the base 1 via a bearing, and two clamping assemblies 8 are set on the top of the rotating test platform 6. The car charger 7 is placed on the top of the rotating test platform 6. The rotating test platform 6 with its rotating design can quickly adjust the position of the car charger 7 by rotating the rotating test platform 6 during the subsequent testing process, which is convenient for extrusion testing on other parts of the surface of the car charger 7.

[0028] And a quick-stop structure is provided between the rotary test platform 6 and the base 1 for quick-stopping after the rotary test platform 6 rotates.

[0029] In this embodiment, preferably, the quick-closing structure includes an inner slide groove 94 inside the rotary test bench 6, a spring 95 and an inner slide block 96 disposed within the inner slide groove 94, a pressing block 91 and a limiting rod 92 welded and fixed to the bottom surface of the inner slide block 96. The inner slide block 96 is movably mounted in the inner slide groove 94 by the spring 95. The top surface of the base 1 has multiple limiting slots 93 corresponding to the limiting rods 92 arranged in a circular array with the center point of the rotary test bench 6 as the center point. The bottom end of the limiting rod 92 penetrates into the interior of one of the limiting slots 93, realizing stable positioning of the rotary test bench 6 during daily use. The bottom end of the pressing block 91 penetrates into the rotary test bench 6. On the bottom surface, the operator only needs to press down the pressing block 91, causing the inner slide block 96 to move upward and compress the spring 95, which will cause the limiting rod 92 to move upward until the bottom end of the limiting rod 92 moves out of the limiting slot 93, quickly releasing the limitation on the rotary test platform 6. At this time, the rotary test platform 6 can be rotated on the top of the base 1 to change the position of the car charger 7. When it is rotated to the appropriate position, the operator only needs to release the pressing block 91. Under the push of the spring 95, the inner slide block 96 moves downward with the pressing block 91 and the limiting rod 92, so that the bottom end of the limiting rod 92 can be inserted into the limiting slot 93 in other positions, thus quickly completing the limitation after the rotary test platform 6 is rotated.

[0030] In this embodiment, preferably, a circular mounting groove is provided on the top surface of the inner slide 96, and the bottom end of the spring 95 is inserted into the circular mounting groove to limit the spring 95 and prevent the spring 95 from deviating in the future.

[0031] In this embodiment, preferably, the inner wall of the bottom end of the inner groove 94 is provided with a pressing hole corresponding to the pressing block 91, and the pressing hole is connected to the bottom surface of the rotary test platform 6.

[0032] In this embodiment, preferably, the inner wall at the bottom end of the inner groove 94 is also provided with a rod hole for the limiting rod 92 to pass through, and the rod hole is connected to the bottom surface of the rotating test platform 6.

[0033] In this embodiment, preferably, the clamping assembly 8 includes a vertical plate 81 welded and fixed to the top surface of the rotary test bench 6, a threaded rod 82 that passes through the vertical plate 81 and is threadedly connected to the vertical plate 81, an L-shaped pressure block 83 that is slidably installed on the top of the rotary test bench 6 and rotatably connected to one end of the threaded rod 82, and a rubber pad 84 installed on the side of the L-shaped pressure block 83. In actual use, the L-shaped pressure block 83 and the rubber pad 84 can be moved to the side by rotating and twisting the threaded rod 82 until the rubber pad 84 is pressed against the side of the car charger 7, thus completing the clamping of the car charger 7.

[0034] In this embodiment, preferably, the surface of the upright plate 81 is provided with a threaded hole through which the threaded rod 82 passes.

[0035] Example 2

[0036] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the strip-shaped insert 841, the side locking block 842 and the strip-shaped insert hole 831 can be set to facilitate the subsequent disassembly and replacement of the rubber pad 84.

[0037] Specifically, one side surface of the rubber pad 84 is provided with two integrated strip-shaped inserts 841, and the end of each strip-shaped insert 841 is provided with an integrated side locking block 842. Both are made of rubber and will undergo elastic deformation when compressed. The surface of the L-shaped pressure block 83 has two strip-shaped insertion holes 831 corresponding to the strip-shaped inserts 841. The end of the strip-shaped insert 841 passes through the strip-shaped insertion holes 831 to the other side of the L-shaped pressure block 83, and the side locking block 842 is locked onto the other side surface of the L-shaped pressure block 83. At this time, the side locking block 842 can limit the strip-shaped insert block 841 and the rubber pad 84, ensuring the installation stability of the rubber pad 84. If the rubber pad 84 needs to be removed for maintenance and replacement, simply push the strip-shaped insert block 841 and the side locking block 842 forcefully, so that the strip-shaped insert block 841 and the side locking block 842 are squeezed and elastically deformed until the strip-shaped insert block 841 and the side locking block 842 are squeezed out from the strip-shaped insertion hole 831, and the rubber pad 84 can be easily removed from the side of the L-shaped pressure block 83 for replacement.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
