Description

Technical Field

[0001] This utility model belongs to the field of electrical control box technology, specifically a detection structure for electrical control boxes in new energy vehicles. Background Technology

[0002] A waterproof performance testing device for electrical control cabinets, disclosed in publication number CN214702640U, includes a testing base. A placement plate is movably connected inside the testing base, and a rotating disk is movably connected to the top of the placement plate. A connecting frame is fixedly connected to the top of the testing base, and a nozzle is fixedly connected to the bottom of the connecting frame. A slide rail is fixedly connected to the bottom rear side of the top frame, and a testing cover is movably connected to the front side of the slide rail. Several fixing grooves are formed on the upper surface of the rotating disk, and springs are fixedly connected inside the fixing grooves. Fixing blocks are fixedly connected to the outside of the springs. When a leak occurs in the electrical control cabinet, the testing cover is pressed tightly against the outer wall of the cabinet. Clean water from a water tank enters the testing cover through a hose, and the water inside the testing cover is used to detect leaks on the outer wall of the electrical control cabinet, thus detecting leaks on one side of the cabinet's outer wall. Rotating the rotating disk allows for the detection of other untested sides of the cabinet, facilitating the identification of leak points.

[0003] However, the aforementioned methods for testing the waterproofness of electrical control boxes have several shortcomings. For example, during the testing process, dust, oil, and other debris often adhere to the surface of the control box. This debris can easily obscure the surface, leading to inaccurate test results and potentially misleading production decisions. Furthermore, after the waterproof test, water droplets or moisture often remain inside the control box, requiring a lengthy drying process. This not only prolongs the testing cycle but also increases production costs. Utility Model Content

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1:

[0028] Please see Figures 1-3This application provides a detection structure for a new energy vehicle electrical control box, including a main frame 1 and a water spray detection head 16. A first fixed seat 2 is fixedly connected to the main frame 1, and a swing drying mechanism is provided on the first fixed seat 2. The structure includes a disc 4 rotatably connected to the first fixed seat 2, driven to rotate by a first drive motor 3, which is mounted on the first fixed seat 2. An eccentric shaft 5 is eccentrically mounted on the disc 4, which generates an up-and-down swinging force. A sliding sleeve 6 is fixedly connected to the end of the eccentric shaft 5 away from the disc 4. The structure also includes a connecting shaft 8 fixedly connected to the first fixed seat 2 by a first connecting rod 7. A second connecting rod 9 is rotatably connected to the connecting shaft 8, and a fixed shaft 10 is fixedly connected to the second connecting rod 9. The sliding sleeve 6 is slidably connected to the fixed shaft 10, and a fan assembly 11 is provided on the second connecting rod 9. The fan assembly 11 is an existing product and is only used to dry the damp electrical control box.

[0029] Specifically, by starting the first drive motor 3, the disc 4 is driven to rotate. The rotation of the disc 4 drives the eccentric shaft 5 to rotate. The rotation of the eccentric shaft 5 causes the sliding sleeve 6 to slide on the fixed shaft 10, while simultaneously causing the fixed shaft 10 to swing up and down around the connecting shaft 8 via the second connecting rod 9. The second connecting rod 9 drives the fan assembly 11 to swing up and down repeatedly. Thus, after the water spray detection head 16 sprays water to detect that there is no problem with the new energy vehicle's electronic control box, the fan assembly 11 accelerates the drying process, shortens the detection cycle, and the swinging air can thoroughly dry the device, avoiding localized dampness.

[0030] Example 2:

[0031] Based on Embodiment 1, a connecting frame 17 is fixedly connected to the water spray detection head 16, and a cleaning mechanism is provided on the connecting frame 17; including a second fixed seat 18, an electric push rod 20 is provided on the second fixed seat 18, a brush 21 is fixedly connected to the output end of the electric push rod 20, a second guide shaft 19 is fixedly connected to the main frame 1, the second fixed seat 18 is slidably connected to the second guide shaft 19, the second fixed seat 18 moves up and down with the water spray detection head 16 during the process of the second fixed seat 16 moving up and down, and the second guide shaft 19 can play a guiding and limiting role.

[0032] Specifically, during the water spray test when the water spray head 16 reciprocates up and down on one side of the new energy vehicle's electronic control box, the connecting frame 17 drives the second fixed seat 18 to reciprocate up and down. The second fixed seat 18 drives the electric push rod 20 on it to reciprocate up and down along the second guide shaft 19. Before this, the electric push rod 20 is activated to push the brush 21 to adhere to the untested surface of the new energy vehicle's electronic control box. This allows the brush 21 to clean away debris adhering to the surface of the new energy vehicle's electronic control box before the waterproof test, so as to prevent debris from obscuring the box surface and affecting the accuracy of the test results.

[0033] Example 3:

[0034] Based on Embodiment 2, a collection box 24 is provided at the lower end of the main frame 1 to collect water that flows down during the testing of the waterproof performance of the new energy vehicle's electronic control box. A rotating disk assembly 22 is connected to the upper part of the collection box 24 via a rotating shaft. The rotation of the rotating disk assembly 22 allows for individual testing of different surfaces of the new energy vehicle's electronic control box. The upper surface of the collection box 24 and the rotating disk assembly 22 are both equipped with evenly distributed rotating disk assemblies 22. This arrangement allows water to flow into the interior of the collection box 24, while dirt remains on the upper surface of the collection box 24. A water tank 27 is installed on the frame 1. A delivery pump is installed inside the water tank 27. The delivery pump is connected to the water spray detection head 16 through a second connecting pipe 28. It can deliver water to the water spray detection head 16 and spray it onto the outer surface of the new energy vehicle's electronic control box. A circulation pump 26 is installed on the main frame 1. One end of the circulation pump 26 is connected to the collection tank 24 through a first connecting pipe 25. The other end of the circulation pump 26 is connected to the water tank 27 through a first connecting pipe 25. It is used to pump the water collected inside the collection tank 24 back into the water tank 27 for recycling and saving water resources.

[0035] Specifically, the water sprayed by the water spray detection head 16 flows along the surface of the new energy vehicle's electronic control box to the rotating disk assembly 22 and the collection box 24, and then enters the collection box 24 through the filter hole 23 to complete the collection. The circulation pump 26 is started to pump the water collected in the collection box 24 into the water tank 27 through the first connecting pipe 25, so as to achieve recycling and save resources.

[0036] In this embodiment, a lead screw 12 is rotatably connected to the main frame 1, and a threaded block 14 is threadedly connected to the lead screw 12, and the threaded block 14 is fixedly connected to the water spray detection head 16; a first guide shaft 15 is also fixedly connected to the main frame 1, and the threaded block 14 is slidably connected to the first guide shaft 15. By starting the second drive motor 13, the lead screw 12 is driven to rotate, thereby causing the threaded block 14 to move up and down along the first guide shaft 15. The threaded block 14 drives the water spray detection head 16 to perform comprehensive water spray detection on a certain surface of the new energy vehicle's electronic control box.

[0037] In this embodiment, the fan assembly 11 and the brush 21 are respectively arranged on both sides of the water spray detection head 16, which allows the detection process to start in a specified manner. First, the brush 21 is used for cleaning, then the water spray detection head 16 is used for water spraying detection, and then the fan assembly 11 is used for drying, which is highly continuous.

[0038] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
