Description

Technical Field

[0001] The invention relates to detection equipment technology, in particular to a detection device used for battery box processing. Background Art

[0002] With the development of electric vehicles, the power battery casing, as the core component of pure electric vehicles, directly affects the safety of the entire vehicle. The development of the power battery casing needs to fully consider various safety factors, and repeatedly verify and optimize the design scheme to prevent the accumulation of pressure in the power battery casing and cause safety accidents. Therefore, it is necessary to perform an airtightness test on the battery box. The airtightness test is also called a sealing test or a waterproof test. Because many products are assembled by welding or molded, it is inevitable that there will be deviations in the operation, resulting in poor product sealing. If the product wants to achieve a certain level of waterproof and dustproof or safety, it must be tested for airtightness.

[0003] A Chinese invention patent with publication number CN113325319B discloses a device and method for testing battery performance. The device and method for testing battery performance, by setting a clamping mechanism, can provide a good clamping effect on the battery during measurement to prevent the battery from shaking due to the external environment, which would make the test data inaccurate. By setting a shock-absorbing mechanism, the rotation of the threaded column and the deformation of the connecting spring are utilized to enable the test board to provide a good shock-absorbing effect during battery testing.

[0004] When the existing equipment is in use, for electric vehicles or other application fields, the battery box needs to withstand vibration and impact, but during the inspection, the pressure resistance and seismic resistance of the battery box cannot be simultaneously tested, which makes the accuracy of the inspection of the inner cavity of the battery box low.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Example: See Figure 1-Figure 8 A detection device for battery box processing includes an operating table 1. Support columns 11 are symmetrically arranged on the upper end of the operating table 1. Guide grooves 12 are opened on the opposite sides of the two support columns 11. Vibration components 2 and positioning components 3 are slidably installed on the inner walls of the guide grooves 12. The battery box is limited by the positioning component 3, and the vibration component 2 is used to simulate the operating state.

[0039] In this solution, the inner cavity of the support column 11 is provided with a device with telescopic function such as an electric telescopic rod, and is connected to an external control device. When the electric telescopic rod is started, the vibration component 2 and the positioning component 3 arranged at its output end are synchronously driven to move, so that the vibration component 2 and the positioning component 3 are in the optimal position.

[0040] The movement of the vibration assembly 2 and the positioning assembly 3 is limited by the guide groove 12, so that the vibration assembly 2 and the positioning assembly 3 remain stable as a whole when moving.

[0041] Furthermore, the vibration assembly 2 includes a connecting plate 21 connected to the supporting column 11 , and slide plates 22 are slidably mounted on both sides of the connecting plate 21 , and a vibration plate 23 is arranged at the upper end of the slide plate 22 .

[0042] In this embodiment, the outer surface of the end of the connecting plate 21 is slidably connected to the inner wall of the guide groove 12. At the same time, vibration grooves are opened on both sides of the connecting plate 21, and the inner wall of the vibration groove is slidably connected to the outer surface of the slide plate 22, so that there will be no interference when the vibration plate 23 moves up and down.

[0043] Furthermore, a support plate 24 is provided on one side of the connecting plate 21, a driving member 25 is provided at the lower end of the support plate 24, a rotating block 26 is provided at the output end of the driving member 25, and a movable rod 27 is slidably installed at the end of the rotating block 26 and away from the driving member 25.

[0044] Specifically, the driving member 25 is a device with power output such as a motor, and is connected to an external control device. When the driving member 25 is started, it synchronously drives the rotating block 26 arranged at its output end to rotate, and then drives the movable rod 27 slidably installed on the rotating block 26 to rotate around the output end of the driving member 25, wherein the movable rod 27 can slide up and down at the end of the rotating block 26.

[0045] Furthermore, a fixed block 28 is symmetrically arranged at the end of the support plate 24, and a rotating shaft 29 is rotatably installed on the inner wall of the fixed block 28. Vibrating blocks 291 are arranged at both ends of the rotating shaft 29. The outer surface of the vibrating block 291 is fitted with the lower end of the vibration plate 23. A driving plate 292 is arranged on the outer surface of the rotating shaft 29. A limiting rod 293 is arranged at the end of the driving plate 292. The outer surface of the limiting rod 293 is slidably connected to the inner wall of the movable rod 27.

[0046] Specifically, when the rotating block 26 rotates, the movable rod 27 drives the limit rod 293 to shake. Since the outer surface of the limit rod 293 is connected to the rotating shaft 29 through the driving plate 292 and the outer surface of the rotating shaft 29 is limited by the fixed block 28, the vibration block 291 fixed at the end of the rotating shaft 29 shakes, thereby squeezing the vibration plate 23, causing the vibration plate 23 to move up and down, performing a bump test on the battery box and detecting the internal sealing state of the battery box.

[0047] Furthermore, the positioning assembly 3 includes a movable plate 31 connected to the support column 11, a positioning plate 32 is symmetrically arranged on the upper end of the movable plate 31, and a through hole 33 is opened at the end of the positioning plate 32, and an adjustment rod 34 is slidably installed on the inner wall of the through hole 33.

[0048] In this embodiment, the adjustment rod 34 is limited by the through hole 33, and the outer surface of the end of the movable plate 31 is slidably connected to the inner wall of the guide groove 12, thereby adjusting the height of the battery box to make it suitable for different scenarios.

[0049] Furthermore, a clamping block 35 is provided on the outer surface of the adjusting rod 34, and a push rod 36 is provided on the outer surface of the adjusting rod 34 and on one side of the clamping block 35. An extrusion rod 37 is rotatably installed on the outer surface of the push rod 36, and a docking block 38 is provided at the end of the extrusion rod 37, and the battery box is fixed by the docking block 38.

[0050] Specifically, the battery box is clamped by the docking block 38, thereby squeezing the battery box so that the battery box is in a stable state, and when the docking block 38 moves, it drives the squeezing rod 37 to move, and at the same time drives the push rod 36 to move, thereby synchronously driving the adjustment rod 34 to move. Since the end of the clamping block 35 is connected to the adjustment rod 34, the clamping block 35 rotates around the rotating rod 352 to limit the outer surface of the battery box.

[0051] Furthermore, a limiting groove 351 is provided on one side of the clamping block 35, a rotating rod 352 is slidably mounted on the inner wall of the limiting groove 351, and the end of the rotating rod 352 is connected to the inner wall of the positioning plate 32. A protective groove 361 is provided on the outer surface of the push rod 36, and a protective rod 362 is slidably mounted on the inner wall of the protective groove 361, and the end of the protective rod 362 is connected to the inner wall of the positioning plate 32.

[0052] Specifically, the rotation rod 352 is limited by the limiting groove 351 provided on the clamping block 35, so that when the adjusting rod 34 moves, the clamping block 35 is driven to rotate.

[0053] At the same time, the protection rod 362 is limited by the protection groove 361 set on the push rod 36, so that when the push rod 36 rotates, the protection groove 361 is used to protect the push rod 36 to prevent the push rod 36 from falling off when moving.

[0054] Furthermore, an elastic member 39 is provided at a middle position of the end of the movable plate 31 , and an end of the elastic member 39 is connected to the lower end of the docking block 38 .

[0055] Specifically, the elastic member 39 is an elastic member such as a spring, and the docking block 38 is limited by the elastic member 39 so that when the docking block 38 leaves the battery box, the elastic member 39 pushes the docking block 38 to the initial position to facilitate subsequent detection.

[0056] Furthermore, the impact assembly 4 is mounted on the upper end of the operating table 1, and the battery box is subjected to a simulated collision through the impact assembly 4. The impact assembly 4 includes a bottom plate 41 connected to the operating table 1, and a support rod 42 is disposed at the upper end of the bottom plate 41. A power member 43 is disposed on one side of the support rod 42, and a spiral rod 44 is disposed at the output end of the power member 43.

[0057] In this embodiment, the power part 43 is a device with power output such as a motor, and is connected to an external control device. When the power part 43 is started, it synchronously drives the screw rod 44 arranged at its output end to rotate. At the same time, the power part 43 and the screw rod 44 are supported by the support rod 42, so that they are in a stable state as a whole during operation.

[0058] At the same time, a movable groove 13 is opened at the upper end of the operating table 1, and the inner wall of the movable groove 13 is provided with a device with a telescopic function such as an electric telescopic rod, so that the entire impact assembly 4 can be driven by the electric telescopic rod to adjust its position, making it suitable for different scenes.

[0059] Furthermore, a transmission block 45 is provided at the upper end of the bottom plate 41 and between the two support rods 42 , and the outer surface of the transmission block 45 is in contact with the outer surface of the spiral rod 44 .

[0060] Specifically, a plurality of groups of protrusions are evenly arranged on the outer surface of the transmission block 45 , and when the spiral rod 44 rotates, the transmission block 45 is driven to rotate.

[0061] Furthermore, a sleeve 46 is provided at the upper end of the bottom plate 41 and on one side of the transmission block 45, and the end of the transmission block 45 penetrates and extends to the inner cavity of the sleeve 46. A crankshaft 47 is provided at the end of the transmission block 45, and a plurality of groups of pressing rods 48 are provided on the outer surface of the crankshaft 47. A slot 461 corresponding to the pressing rod 48 is provided on the outer surface of the sleeve 46, and the inner wall of the slot 461 is slidably connected to the outer surface of the pressing rod 48.

[0062] Specifically, when the transmission block 45 rotates, it synchronously drives the crankshaft 47 arranged at its end to perform a collision test. Since a plurality of pressing rods 48 are arranged on the outer surface of the crankshaft 47, when the crankshaft 47 rotates, the pressing rods 48 are driven to move up and down, thereby performing a collision test on the lower end of the battery box, thereby detecting the battery box more accurately.

[0063] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0064] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
