Description

Technical Field

[0001] The present invention relates to the field of measurement technology, in particular to a measuring instrument for new energy equipment. Background Art

[0002] The terminal of the new energy battery consists of a stud, gasket and nut on the top. Multiple groups of new energy batteries are placed in the battery box inside the vehicle, one end of the line is fixed to the terminal (pole) of the new energy battery, and the cover of the battery box is closed to seal the new energy battery. The vehicle is powered by the new energy battery to drive the vehicle. There is a certain safety gap between the cover and the terminal of the new energy battery. Since the cover of the factory vehicle is often subjected to force and compression during use, the safety gap of the factory vehicle needs to be strictly controlled. Usually, there should be a gap of more than 30mm between the cover and the terminal of the new energy battery. If the cover and the live part are effectively insulated, the gap should be at least 10mm. Similarly, according to the standards of the International Electrotechnical Commission (IEC), such as IEC61851, the safety gap between the high-voltage terminal in the charging pile and the metal casing of the charging pile is usually clearly specified, and the voltage level needs to be considered because the safety distance is different under different voltages. For example, the voltage of DC fast charging is higher, and a larger gap may be required.

[0003] In the existing technology, when measuring the gap, it is necessary to close the box cover or shell. After the cover is closed, the tool cannot be inserted, making it difficult to effectively measure the gap distance. If there is an insulating layer, it is necessary to place an insulating object with a flat side against the port of the new energy battery box, wear insulating gloves, and use a steel ruler to measure the distance between the new energy battery electrode and the insulating object, and then measure the depth of the recess of the new energy battery box cover. The sum of these two data minus the overlapping part of the new energy battery box cover and the new energy battery box is the data to be measured. The measurement process is difficult and cumbersome, which reduces work efficiency. Similarly, when measuring the distance between the high-voltage terminal in the charging pile and the metal shell of the charging pile, similar problems will be encountered. The internal space is not visible after the shell is encapsulated, and common tools cannot effectively measure it.

[0004] Therefore, the present invention provides a measuring instrument that is convenient for measuring the gap between the terminal and the metal part (cover or shell) of new energy vehicle batteries or new energy charging piles and other similar equipment. Summary of the Invention

[0022] Example: Figures 1-9 As shown, a measuring instrument for new energy equipment described in the present invention includes a contact detection box 11, an inverted T-slot 12 is provided on the top of the detection box 11, a plurality of limiting holes 13 are provided through the top of the detection box 11, and the limiting holes 13 are communicated with the inverted T-slot 12, an outer rotation groove 16 is provided at the bottom of the inverted T-slot 12, an extension platform 14 is fixedly installed on the side of the detection box 11 close to the C-ring 25, a placement groove 15 is provided on the extension platform 14 and the top of the detection box 11, and the placement groove 15 is communicated with the inverted T-slot 12, an inner rotation groove 17 is provided inside the detection box 11, a sliding hole 18 is provided through the inside of the detection box 11, and the sliding hole 18 is communicated with the inner rotation groove 17.

[0023] Specifically, the detection box 11 can provide an opening space for the inverted T-slot 12, the inverted T-slot 12 can provide a sliding space for the C-plate 31, and the limiting hole 13 can provide a limiting function for the limiting column 34. When the C-plate 31 drives the limiting column 34 to slide, the limiting column 34 and the limiting hole 13 cooperate to limit the sliding distance of the C-plate 31, thereby limiting the movement of the top plate 36. The detection box 11 can provide a stable support for the extension platform 14, and the extension platform 14 can provide an opening space for the placement slot 15. The placement slot 15 can provide a storage space for the telescopic plate 39. The outer rotating groove 16 can provide a rotation space for the hollow input end of the hollow column 41, and the inner rotating groove 17 can provide a rotation space for the solid output end of the hollow column 41 and the gear 43.

[0024] In this embodiment, a positioning mechanism 2 is provided on one side of the detection box 11. The positioning mechanism 2 positions the detection box 11 by clamping a C-ring 25 provided on one side of the detection box 11 onto the outside of the nut of the new energy battery terminal. The positioning mechanism 2 includes two slide grooves 21, and the two slide grooves 21 are opened on one side of the detection box 11. A bidirectional screw rod 22 is installed inside the detection box 11 through a bearing, and the bidirectional screw rod 22 is located on the inner side of the slide groove 21. A rotating head 23 is fixedly installed at one end of the bidirectional screw rod 22. Two threaded tubes 24 are installed on the outer thread of the bidirectional screw rod 22, and the threaded tube 24 is slidably installed on the inner side of the slide groove 21. The C-ring 25 is fixedly installed on one side of the threaded tube 24, and a rubber block 26 is fixedly installed on the inner side of the C-ring 25.

[0025] Specifically, the detection box 11 can provide an opening space for the slide groove 21, the slide groove 21 can provide a moving space for the bidirectional screw rod 22 and the threaded tube 24, the bidirectional screw rod 22 can provide a stable support for the rotating head 23, the threaded tube 24 can provide a stable support for the C-ring 25, the C-ring 25 can provide a stable support for the rubber block 26, the rotating head 23 can provide a grasping space for the staff, the staff grasps the rotating head 23 and rotates it, so that the rotating head 23 drives the bidirectional screw rod 22 to rotate, and the bidirectional screw rod 22 uses the thread action to drive the threaded tube 24 to move, thereby adjusting the distance between the two C-rings 25. Because the final fixing direction of the nut is different, the C-ring 25 is clamped on the outside of the nut of the new energy battery terminal through the rubber block 26, which can prevent the position and direction of the thread from affecting the positioning mechanism 2.

[0026] In this embodiment, the support mechanism 3 is provided inside the detection box 11; the support mechanism 3 is assembled to rotate the two support plates 35 provided inside the detection box 11 so that the support plates 35 drive the top plate 36 on the top thereof to move up and down; the support mechanism 3 includes a C-shaped plate 31, and the C-shaped plate 31 is located inside the inverted T-slot 12, a support block 32 is fixedly installed on the top of the C-shaped plate 31, a push plate 33 is fixedly installed on the top of the support block 32, and the push plate 33 is located on the top of the detection box 11, and two limit columns 34 are fixedly installed on the top of the C-shaped plate 31. The limiting columns 34 are respectively located on both sides of the support block 32, and the limiting columns 34 are located on the inner side of the limiting hole 13. One end of the support plate 35 is rotatably installed on the inner side of the C-shaped plate 31, and the other end of the support plate 35 is hingedly installed with a top plate 36. A storage groove 37 is provided on the top of the top plate 36. A pull ring 38 is installed inside the top plate 36 through a bearing, and the pull ring 38 is located on the inner side of the storage groove 37. A telescopic plate 39 is hingedly installed on one side of the top plate 36, and one end of the telescopic plate 39 is rotatably installed inside the extension platform 14. The telescopic plate 39 is located on the inner side of the placement groove 15.

[0027] Specifically, the C-shaped plate 31 can provide stable support for the support block 32 and the push plate 33, the top plate 36 can provide an opening space for the storage groove 37, the storage groove 37 can provide a storage space for the pull ring 38, and the telescopic plate 39 can provide a limiting function for the top plate 36. When the top plate 36 moves up and down, the extension and contraction of the telescopic plate 39 can ensure that the top plate 36 can only move in the vertical direction, preventing the top plate 36 from shifting to the left or right position. The limiting effect of the limiting column 34 and the limiting hole 13 can prevent the top plate 36 from driving the support plate 35 to rotate to a vertical state, preventing the top plate 36 from being stuck due to the support plate 35 when it is subsequently subjected to downward pressure.

[0028] In this embodiment, the measuring mechanism 4 is assembled to provide rotational support for the spring bar 42 on the outside through a hollow column 41 arranged on the inner side of the detection box 11. One end of the spring bar 42 is fixedly connected to the bottom of the top plate 36. The support plate 35 drives the hollow column 41 to rotate through the spring bar 42, so that the hollow column 41 drives the measuring ruler 44 arranged on the top thereof to move left and right. The scale 46 on the top of the measuring ruler 44 is exposed to the outside. The hollow column 41 is composed of two rods of different thicknesses. The thick rod is the input end and is in a hollow state. The thin rod is the output end and is in a solid state. The two ends of the hollow column 41 are respectively penetrated by bearings. It is installed inside the detection box 11, and the hollow input end of the hollow column 41 is located on the inner side of the outer rotating groove 16, and the solid output end is located on the inner side of the inner rotating groove 17. One end of the spring bar 42 is fixedly installed on the outer side of the hollow column 41 and spirally wound on the outer side of the hollow input end of the hollow column 41. A gear 43 is fixedly installed on the outer side of the solid output end of the hollow column 41, and the gear 43 is located on the inner side of the inner rotating groove 17. A measuring ruler 44 is slidably placed on the inner side of the sliding hole 18. A tooth groove 45 is provided at the bottom of the measuring ruler 44, and the tooth groove 45 is engaged with the gear 43. A scale 46 is engraved on the top of the measuring ruler 44.

[0029] Specifically, the top plate 36 can provide a stable support for one end of the spring bar 42, and the hollow column 41 can provide a stable support for the other end of the spring bar 42. At the same time, the spring bar 42 can provide rotational power for the hollow column 41. The hollow state of the thicker part of the hollow column 41 can reduce the power required for the rotation of the hollow column 41. The spring bar 42 in the spirally wound state can reduce the influence of the thickness of the spring bar 42 on the measurement result. When the top plate 36 moves upward, the top plate 36 drives one end of the spring bar 42 to move upward, so that the spring bar 42 is gradually disassembled from the surface of the hollow column 41. During the disassembly process, the hollow column 41 can be driven to rotate in the opposite direction. When the top plate 36 moves to the highest point The spring bar 42 is straightened. When the top plate 36 moves downward, the spring bar 42 is self-wound and wrapped around the surface of the hollow column 41 under the action of its own elastic force. The force of the spring bar 42 when it is self-wound drives the hollow column 41 to rotate forward. The hollow column 41 can provide rotational power for the gear 43. The measuring ruler 44 can provide a space for the tooth groove 45. The measuring ruler 44 can provide a carving space for the scale 46. When the hollow column 41 rotates in the opposite direction, it drives the gear 43 to rotate, so that the gear 43 drives the measuring ruler 44 to move out to the outside by meshing with the tooth groove 45. Conversely, the measuring ruler 44 is stored in the inner side of the sliding hole 18, and the gap size is determined by the scale 46 at one end of the sliding hole 18.

[0030] Working principle: With the initial state as Figure 1As shown, when the staff needs to measure the insulation spacing of the new energy battery terminal, they first grab the rotating head 23 and rotate it, so that the rotating head 23 drives the bidirectional screw 22 to rotate under the action of external force. The bidirectional screw 22 uses the threaded action with the threaded tube 24 to drive the two C-rings 25 to move closer to or away from each other, thereby adjusting the distance between the two C-rings 25. Then, the detection box 11 is placed on the top of the new energy battery, and the two C-rings 25 are clamped on the outside of the nuts of the two terminal terminals of the new energy battery, so that the detection box 11 is positioned; Then the staff member grabs the pull ring 38 and moves it upward, so that the pull ring 38 is first moved out of the storage groove 37 under the action of external force, and then drives the top plate 36 to move upward. The top plate 36 drives one end of the telescopic plate 39 to move upward through the hinge action. The telescopic plate 39 extends and rotates. At the same time, the top plate 36 drives one end of the two support plates 35 to move upward, so that the support plate 35 drives the C-shaped plate 31 to slide along the inner side of the inverted T-slot 12 through the hinge action of the other end. The two C-shaped plates 31 move in the direction of approaching each other, and the C-shaped plate 31 drives the limiting column 34 to slide along the inner side of the limiting hole 13. When the limiting column 3 When the top plate 36 slides to the inner wall of one end of the limiting hole 13, the top plate 36 moves to the highest position. At the same time, the top plate 36 moves upward, driving one end of the spring bar 42 to move upward, causing the spring bar 42 to gradually disassemble from the surface of the hollow column 41. When the top plate 36 moves to the highest position, the spring bar 42 is straightened. The disassembly process of the spring bar 42 drives the hollow column 41 to rotate in the opposite direction, and then drives the gear 43 to rotate through the hollow column 41. The gear 43, through the meshing action with the tooth groove 45, drives the measuring ruler 44 to move from the inner side of the sliding hole 18, so that the side of the measuring ruler 44 with the scale 46 is completely exposed to the outside world. The staff closes the cover of the new energy battery, causing the cover to press downward against the top plate 36. As the top plate 36 moves downward, the spring bar 42, under its own elastic force, drives the hollow column 41 to rotate forward, causing the measuring ruler 44 to gradually enter the inner side of the sliding hole 18. When the cover is completely closed, only a portion of the measuring ruler 44 is exposed to the outside. The cover is opened to check the exposed measuring ruler 44. The reading of the scale 46 at this time is the insulation spacing of the new energy battery. When it is necessary to measure again, the measuring device is moved to the position to be measured. It is only necessary to grasp the two push plates 33 and move them toward each other, and move the top plate 36 to the top to reset it, and then measurement can be carried out again.

[0031] Similarly, when it is necessary to measure the gap between the conductive terminal and metal parts of new energy charging piles and other similar equipment, a similar operation method can be used for measurement.
