Description

Technical Field

[0001] This utility model relates to the field of charging pile frame detection technology, and more specifically to a charging pile frame strength detection device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the demand for charging piles as infrastructure has surged. The mid-frame structure of a charging pile is its core supporting component, usually made of metal or high-strength composite materials, and is responsible for bearing the internal electrical components, heat dissipation system, and external environmental loads.

[0003] Its structural strength is directly related to the long-term stability, safety and service life of the charging pile. If the strength of the middle frame is insufficient, it may lead to structural deformation, damage to internal components or even safety accidents. Therefore, it is essential to conduct strict mechanical performance testing on the middle frame.

[0004] A search revealed a Chinese patent with publication number CN220207264U, which discloses a strength testing device. This device can perform clamping operations in an adaptive adjustment manner when conducting strength testing on parts of different specifications, which improves the stability and applicability of the mechanism to a certain extent. However, during the test, the staff cannot directly observe the pressure that the test piece bears when it deforms. Utility Model Content

This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides a charging pile frame strength testing device, including a workbench 1. A retractable support platform 3 is bolted to the upper surface of the workbench 1. A groove 4 is formed on the upper surface of the support platform 3, and two symmetrical L-shaped support blocks 9 are slidably connected within the groove 4. A frustum 7 is bolted to the upper surface of the workbench 1, located below the support platform 3. A pressure sensor 8 is bolted to the upper surface of the frustum 7, and the upper surface of the pressure sensor 8 contacts the lower surface of the support platform 3. A mounting frame 2 is bolted to the upper surface of the workbench 1. A display screen electrically connected to the pressure sensor 8 is provided on the top inner wall of the mounting frame 2. A cylinder 5 is bolted to the top inner wall of the mounting frame 2, and the output end of the cylinder 5 is bolted to... A pressure head assembly 6 is fixedly connected, and a straightening assembly 10 for straightening the middle frame is provided at both ends of the upper surface of the support platform 3. When it is necessary to test the strength of the middle frame, the charging pile middle frame to be tested is first placed on two L-shaped support blocks 9, and then the cylinder 5 is activated to extend. During the extension of the cylinder 5, the pressure head assembly 6 will move downward until it contacts the middle frame to be tested. It continues to extend to apply pressure to the middle frame. During this process, the pressure sensor 8 is subjected to force. Since the pressure sensor 8 is electrically connected to the display screen, the data signal of the pressure sensor 8 is transmitted to the display screen for display. Through the pressure sensor 8 and the display screen, the pressure on the middle frame during the test can be observed intuitively, which makes it convenient for the staff to observe the degree of deformation of the middle frame during the pressure process.

[0023] The pressure sensor model is Subaru SBT673.

[0024] In this invention, the straightening component 10 includes a U-shaped platform 14 bolted to the upper surface of the support platform 3. Two symmetrical rotating rods 15 are rotatably connected to the upper surface of the U-shaped platform 14. Each of the two rotating rods 15 has an arc-shaped rod 16 bolted to its top end. A straightening rod 20 is rotatably connected to the upper surface of one end of the arc-shaped rod 16. Gears 18 are bolted to the outer circumference of each of the two rotating rods 15, and the two gears 18 mesh with each other. Limiting grooves 11 are formed at both ends of the upper surface of the support platform 3. A sliding table 12 is slidably connected within the limiting groove 11. A fixing plate 13 is bolted to the upper surface of the sliding table 12. Connecting rods 17 are rotatably connected to both sides of the fixing plate 13 and one side of each of the two arc-shaped rods 16. Threaded rods 19 are rotatably connected between the inner walls of the two sides of the limiting groove 11 via bearings. Rod 19 passes through slide 12 and is threaded to it. One end of the threaded rod 19 passes through one side of support platform 3 and is fixed to a rotating disk by bolts. The outer circumference of the rotating disk is provided with anti-slip texture. Before the test, the threaded rod 19 is rotated. During the rotation of the threaded rod 19, it will drive the slide 12 connected to it to slide along the limiting groove 11. During the sliding of the slide 12, the connecting rod 17 pulls the arc rod 16 to rotate along the rotating rod 15. Due to the gear 18, the two rotating rods 15 rotate in opposite directions at the same time. During the rotation of the arc rod 16, the straightening rod 20 is moved until the two straightening rods 20 contact the two sides of the middle frame. Through the straightening component 10, the two sides of the charging pile middle frame can be limited to prevent the charging pile middle frame from tilting during the test, which would cause experimental errors.

A screw 25 that cooperates with the through hole 23 is provided in the clearance hole 24. When the pressure block 22 needs to be replaced, first remove the screw 25 and then remove it. Then pull the pressure block 22 down until it is completely disengaged from the clearance groove 21 to remove the pressure block 22. Replace it with a new pressure block 22 and reverse the above steps. The pressure block 22 can be replaced by the pressure head assembly 6. By replacing the pressure block 22 with different ends, the contact area between it and the middle frame can be changed, and the pressure on the middle frame under different contact areas can be tested.

[0026] The use of this utility model involves the following steps:

[0027] S1: Before testing, rotate the threaded rod 19. During the rotation of the threaded rod 19, it will drive the slide table 12 connected to it to slide along the limiting groove 11. During the sliding of the slide table 12, the connecting rod 17 will pull the arc rod 16 to rotate along the rotating rod 15. Due to the gear 18, the two rotating rods 15 will rotate in opposite directions at the same time. During the rotation of the arc rod 16, the straightening rod 20 will move until the two straightening rods 20 contact the two sides of the middle frame.

[0028] S2: When it is necessary to test the strength of the middle frame, first place the charging pile middle frame to be tested on two L-shaped support blocks 9, then start the cylinder 5 to extend. During the extension of the cylinder 5, it will drive the pressure head assembly 6 to move downward until it contacts the middle frame to be tested. Continue to extend to apply pressure to the middle frame. During this process, the pressure sensor 8 is subjected to force. Since the pressure sensor 8 is electrically connected to the display screen, the data signal of the pressure sensor 8 is transmitted to the display screen for display.

[0029] S3: When it is necessary to replace the pressure block 22, first remove the screw 25 and then remove it. Then pull the pressure block 22 down until it is completely disengaged from the relief groove 21. Then the pressure block 22 can be removed. Replace it with a new pressure block 22 by reversing the above steps.
