Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle controller testing technology, specifically a test tray device for electric controllers of new energy vehicles. Background Technology

[0002] An electric vehicle controller, or simply EPC, is a core control device used to control the starting, running, forward / reverse, speed, and stopping of the electric vehicle motor, as well as other electronic components. Electric vehicle EPCs undergo performance and safety testing before leaving the factory. During testing, the EPC has three-phase connectors, high-voltage DC connectors, low-voltage connectors, and resolver connectors that need to be connected to the testing circuit and system. However, currently, many EPC three-phase connectors are connected manually by tightening screws. This requires manual screw removal and installation after each product test, and the high-voltage DC connector connection is similarly handled. During production testing, multiple screws need to be removed and installed each time, and with other connectors also needing to be connected, the efficiency is low and cannot meet production testing requirements. Furthermore, the screw tightening torque is difficult to control, posing a risk of loose connections and potential damage to the EPC. There is also a risk that screws may fall onto the EPC during operation, damaging the EPC PCB board. Utility Model Content

[0003] To address the aforementioned problems in existing technologies, the purpose of this utility model is to provide a test tray device for electronic controllers in new energy vehicles. This integrated device combines all the wiring harnesses and water pipe connection fixtures required before testing the electronic controller with the tray device itself. It can both support and clamp the electronic control product and facilitate rapid connection of various ports during testing, including three-phase connection, high-voltage DC connection, low-voltage connection, resolver connection, and water nozzle connection. This significantly shortens the connection time before testing and improves production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A test tray device for an electronic controller of a new energy vehicle includes a base plate and a three-phase connection assembly, a high-voltage DC connection assembly, a cooling assembly, a plug, a positioning component, and a fixing component mounted on the base plate.

The cooling assembly includes an inlet pipe and an outlet pipe, with one end opening of the inlet pipe and one end opening of the outlet pipe respectively aligned with the inlet and outlet of the electronic controller located at the target position. The plug is used to connect to the low-voltage connector on the electronic controller, and the high-voltage DC connection assembly is used to connect to the high-voltage DC connector of the electronic controller. The three-phase connection assembly includes a first lower support block, a first upper support block, a first bent copper block, and a first handle assembly.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] A test tray device for electronic controllers in new energy vehicles, such as Figures 1-6 As shown, it includes a base plate 1, an isolation and protection layer plate 2, a three-phase connection assembly 3, a high-voltage DC connection assembly 4, a cooling assembly, a plug 6, a positioning component 7, a fixing component 8, and a three-phase wire 9.

[0028] Both the base plate 1 and the protective isolation layer 2 are plate-shaped structures. The base plate 1 is a square plate structure and is supported on the workbench. The protective isolation layer 2 is located above the base plate 1, and the protective isolation layer 2 and the base plate 1 are arranged parallel to each other. The protective isolation layer 2 and the base plate 1 are connected by multiple connecting rods 12. The area of ​​the protective isolation layer 2 is smaller than that of the base plate 1. The protective isolation layer 2 has through holes and its outline is irregular, so that components installed on the base plate 1 can extend upwards out of the protective isolation layer 2.

[0029] The three-phase connection assembly 3 is used to connect the three-phase terminals of the electronic controller 10. The three-phase connection assembly 3 is mounted on one end of the base plate 1. The three-phase connection assembly 3 is as follows... Figure 3 , 4 As shown, it includes a first mounting plate 301, a first movable plate 302, a first upright plate 303, a first lower support block 304, a first upper support block 305, a first bent copper block 306, a first compression spring 307, a first handle assembly 308, a first vertical linear guide rail 309, a first horizontal linear guide rail 310, a first fixing member 311, a first limiting member 312, a first limiting plate 313, and a first auxiliary block 314.

[0030] A first mounting plate 301 is fixedly mounted on a base plate 1. A first horizontal linear guide rail 310 is fixedly mounted on the first mounting plate 301, and the length direction of the first horizontal linear guide rail 310 is parallel to the plane of the base plate 1. A first movable plate 302 is slidably disposed on the first horizontal linear guide rail 310, allowing the first movable plate 302 to reciprocate linearly along the length direction of the first horizontal linear guide rail 310. The first movable plate 302 is located above the first mounting plate 301.

[0031] The first limiting member 312 and the first limiting plate 313 are used to limit and fix the first movable plate 302, so that the first movable plate 302 can move within a limited range and be fixed in a set position. Specifically, the first limiting plate 313 is plate-shaped and perpendicular to the first mounting plate 301. There are two first limiting plates 313, which are respectively fixedly connected to both sides of the first movable plate 302. The first mounting plate 301 has two grooves or through holes, the length of which is greater than the length of the first limiting plate 313. The lower ends of the two first limiting plates 313 are respectively inserted into the two grooves or through holes, so that the first limiting plate 313 can only move within the length range of the grooves or through holes, which is equivalent to limiting the movement range of the first movable plate 302. The first mounting plate 301 is also provided with connecting wings at both ends. Two first limiting plates 313 are located between the two connecting wings. Each connecting wing is provided with at least one first limiting member 312. After the first limiting member 312 passes through the connecting wing, it contacts and presses against the first limiting plate 313 to lock the first limiting plate 313 and prevent the first limiting plate 313 from continuing to move.

[0032] The first lower support block 304 is fixedly installed on the first movable plate 302, and the first bent copper block 306 is installed on the first upper support block 305. The upper end of the first bent copper block 306 is fixedly connected to the first upper support block 305 through the first fixing member 311.

[0033] Three first-bend copper blocks 306 are provided, arranged in parallel at intervals. A first upper support block 305 is vertically mounted on a first movable plate 302, and the first upper support block 305 drives the first-bend copper blocks 306 to rise and fall synchronously. Specifically, a first upright plate 303 is fixedly mounted on the first movable plate 302. The first upright plate 303 has a plate-like structure, and its plane is perpendicular to the plane of the first movable plate 302. A first vertical guide rail 309 is fixedly mounted on the first upright plate 303, and its length direction is perpendicular to the length direction of the first horizontal guide rail 310 and the base plate 1. The first upper support block 305 is slidably mounted on the first vertical guide rail 309, allowing it to reciprocate linearly along the length direction of the first vertical guide rail 309.

[0034] In this embodiment, the first bent copper block 306 is L-shaped.

[0035] In this embodiment, the first fixing member 311 is an equal-shoulder screw.

[0036] In this embodiment, the first limiting member 312 is a ball bolt.

[0037] Furthermore, to improve the lifting stability of the first upper support block 305, the first upper support block 305 is fixedly connected to the first auxiliary block 314. The first handle assembly 308 contacts and can drive the first auxiliary block 314, causing the first auxiliary block 314 to rise and fall within a limited range. The upper end of the first auxiliary block 314 is limited by the first upright plate 303, and the lower end is limited by the boss 315. Specifically, the first upright plate 303 is T-shaped, dividing the first upright plate 303 into an upper part, a middle part, and a lower part. The first auxiliary block 314 is an irregularly shaped block, which is fitted into the middle part of the first upright plate 303. The upper width of the first upright plate 303 is greater than the middle width, so that the ends of the upper part of the first upright plate 303 extend beyond the ends of the middle part, and the extended part prevents the first auxiliary block 314 from rising further, thus limiting the upward movement of the first auxiliary block 314. The boss 315 is located at the lower part of the first upright plate 303, preventing the first auxiliary block 314 from continuing to descend, thus limiting the downward movement of the first auxiliary block 314. A first compression spring 307 is provided between the boss 315 and the first auxiliary block 314, with both ends of the first compression spring 307 contacting the boss 315 and the first auxiliary block 314 respectively. The first compression spring 307 is in a compressed state, and due to the pressure of the first compression spring 307, the upper end of the first auxiliary block 314 contacts both ends of the upper part of the first upright plate 303.

[0038] In this embodiment, two first compression springs 307 are provided, and the two first compression springs 307 are respectively located on both sides of the middle part of the first vertical plate 303.

[0039] The portion of the first auxiliary block 314 located on one side of the first upright plate 303 is fixedly connected to the first upper support block 305, while the portion located on the other side of the first upright plate 303 contacts the first handle assembly 308. The portion of the first auxiliary block 314 that contacts the first handle assembly 308 is designated as the first transmission segment 317. The first handle assembly 308 includes a connecting rod, a handle, and a cam. The two ends of the connecting rod are fixedly connected to the handle and the cam, respectively. The cam is rotatably mounted on a crossbeam 316, which is fixed relative to the first upright plate 303. When the handle is operated, the handle drives the cam to rotate via the connecting rod. The cam is located above the first transmission segment 317. When the upper end of the first auxiliary block 314 contacts both ends of the upper part of the first upright plate 303, the proximal end of the cam contacts the first transmission segment 317. When the cam rotates, causing the distal end of the cam to contact the first transmission segment 317, the cam pushes the first transmission segment 317 downwards, causing the first auxiliary block 314 to descend as a whole, simultaneously lowering the first upper support block 305, further compressing the first compression spring 307. The distance between the distal end of the cam and the cam rotation axis is greater than the distance between the proximal end of the cam and the cam rotation axis.

[0040] In this embodiment, the cam of the first handle assembly 308 is a rectangular block, with the proximal end of the cam being the part of the long side of the rectangle in which the cam is located, and the distal end of the cam being the part of the short side of the rectangle in which the cam is located.

[0041] In this embodiment, both the first lower support block 304 and the first upper support block 305 are insulators.

[0042] The high-voltage DC connection assembly 4 is used to connect the high-voltage DC connector of the electronic controller 10. The high-voltage DC connection assembly 4 is mounted on the base plate 1. Figure 5 , 6 As shown, it includes a second mounting plate 401, a second movable plate 402, a second upright plate 403, a mounting block 404, a limiting cover plate 405, a second bent copper block 406, a second compression spring 407, a second handle assembly 408, a second vertical linear guide rail 409, a second horizontal linear guide rail 410, a second fixing member 411, a second limiting member 412, a second limiting plate 413, and a second auxiliary block 414.

[0043] The second mounting plate 401 is fixedly mounted on the base plate 1, and the second horizontal linear guide rail 410 is fixedly mounted on the second mounting plate 401. The length direction of the second horizontal linear guide rail 410 is parallel to the plane of the base plate 1. The second movable plate 402 is slidably disposed on the second horizontal linear guide rail 410, allowing the second movable plate 402 to reciprocate linearly along the length direction of the second horizontal linear guide rail 410. The second movable plate 402 is located above the second mounting plate 401.

[0044] The second limiting member 412 and the second limiting plate 413 are used to limit and fix the second movable plate 402, so that the second movable plate 402 is fixed in a set position. Specifically, the second limiting plate 413 is plate-shaped and perpendicular to the second mounting plate 401. There are two second limiting plates 413, which are respectively fixedly connected to both sides of the second movable plate 402, and the second mounting plate 401 is located between the two second limiting plates 413. Each second limiting plate 413 is provided with at least one second limiting member 412. After passing through the second limiting plate 413, the second limiting member 412 contacts and presses against the second mounting plate 401, thereby locking the second movable plate 402 and preventing the second limiting plate 413 and the second movable plate 402 from continuing to move.

[0045] The second upright plate 403 is fixedly installed on the second movable plate 402. The second upright plate 403 has a plate-like structure, and the plane of the second upright plate 403 is perpendicular to the plane of the second movable plate 402. The second bent copper block 406 is installed on the mounting block 404, and the upper end of the second bent copper block 406 is fixedly connected to the mounting block 404 through the second fixing member 411. The mounting block 404 is vertically mounted on the second upright plate 403, driving the second bent copper block 406 to rise and fall synchronously. Specifically, the second vertical guide rail 409 is fixedly installed on the second upright plate 403, and the length direction of the second vertical guide rail 409 is perpendicular to the length direction of the second horizontal guide rail 410. The mounting block 404 is slidably disposed on the second vertical guide rail 409, so that the mounting block 404 can move linearly back and forth along the length direction of the second vertical guide rail 409.

[0046] In this embodiment, there are two second-bend copper blocks 406, which are arranged in parallel and spaced apart.

[0047] In this embodiment, the second bent copper block 406 is L-shaped. The upper end of the second bent copper block 406 is used to connect to the electronic controller 10, and the lower end is used to connect to the high-voltage test circuit.

[0048] In this embodiment, the second fastener 411 is a shoulder screw.

[0049] In this embodiment, the second limiting member 412 is a ball bolt.

[0050] To improve the installation stability of the second curved copper block 406, a limiting cover plate 405 is provided. The limiting cover plate 405 is connected to the mounting block 404, and the lower end of the copper block 406 is surrounded in the space enclosed by the limiting cover plate 405 and the mounting block 404.

[0051] Furthermore, to improve the lifting stability of the mounting block 404, the mounting block 404 is fixedly connected to the second auxiliary block 414. The second handle assembly 408 contacts and can drive the second auxiliary block 414, causing the second auxiliary block 414 to rise and fall within a limited range. The upper and lower ends of the second auxiliary block 414 are limited by the second upright plate 403. Specifically, the second upright plate 403 is I-shaped, dividing the second upright plate 403 into an upper part, a middle part, and a lower part, and the second auxiliary block 414 is an irregularly shaped block. The second auxiliary block 414 is fitted into the middle part of the second upright plate 403. The upper and lower widths of the second upright plate 403 are both greater than the middle width, so that the ends of the upper part of the second upright plate 403 extend beyond the ends of the middle part, and the extended portion prevents the second auxiliary block 414 from rising further, thus limiting the upward movement of the second auxiliary block 414. Similarly, the lower ends of the second vertical plate 403 extend beyond the middle ends, and the extended portions prevent the second auxiliary block 414 from continuing to descend, thus limiting the downward movement of the second auxiliary block 414.

[0052] A second compression spring 407 is provided between the lower part of the second vertical plate 403 and the second auxiliary block 414. That is, the two ends of the second compression spring 407 contact the lower part of the second vertical plate 403 and the second auxiliary block 414 respectively. The second compression spring 407 is in a compressed state. Due to the pressure of the second compression spring 407, the upper end of the second auxiliary block 414 contacts the two ends of the upper part of the second vertical plate 403.

[0053] In this embodiment, two second compression springs 407 are provided, and the two second compression springs 407 are respectively located on both sides of the middle part of the second vertical plate 403.

[0054] The portion of the second auxiliary block 414 located on one side of the second vertical plate 403 is fixedly connected to the mounting block 404, while the portion located on the other side of the second vertical plate 403 contacts the second handle assembly 408. The portion of the second auxiliary block 414 that contacts the second handle assembly 408 is designated as the second transmission section 415. The structure of the second handle assembly 408 is similar to that of the first handle assembly 308, comprising a connecting rod, a handle, and a cam. The two ends of the connecting rod are fixedly connected to the handle and the cam, respectively. The cam is rotatably mounted on a bracket 416, which is fixedly mounted on the second vertical plate 403. When the handle is operated, the handle drives the cam to rotate via the connecting rod. The cam is located above the second transmission section 415. When the upper end of the second auxiliary block 414 contacts both ends of the upper part of the second vertical plate 403, the proximal end of the cam contacts the second transmission section 415. When the cam driving the second handle assembly 408 rotates, causing its distal end to contact the second transmission section 415, the cam pushes the second transmission section 415 downwards, causing the second auxiliary block 414 to descend as a whole. This causes the mounting block 404 and the second bent copper block 406 to descend synchronously, further compressing the second compression spring 407. The distance between the distal end of the cam and the cam rotation axis is greater than the distance between the proximal end of the cam and the cam rotation axis.

[0055] In this embodiment, the cam of the second handle assembly 408 is a rectangular block, with the proximal end of the cam being the part of the long side of the rectangle in which the cam is located, and the distal end of the cam being the part of the short side of the rectangle in which the cam is located.

[0056] In this embodiment, both the mounting block 404 and the limiting cover plate 405 are insulators.

The electronic controller 10 has a water inlet and an outlet. The cooling assembly includes an inlet pipe 51, an outlet pipe 52, an inlet nozzle 53, and an outlet nozzle 54. One end of the inlet pipe 51 is connected to an external water source, and the other end is connected to the water inlet of the electronic controller 10. A sealing ring is provided at the end of the inlet pipe 51 that connects to the water inlet of the electronic controller 10, forming an inlet nozzle 53 with an end-face sealing function to prevent water leakage at the connection between the inlet pipe 51 and the electronic controller 10. Similarly, one end of the outlet pipe 52 is connected to an external water source, and the other end is connected to the outlet of the electronic controller 10. A sealing ring is provided at the end of the outlet pipe 52 that connects to the electronic controller 10, forming an outlet nozzle 54 with an end-face sealing function. One end of the inlet nozzle 53 of the inlet pipe 51 and one end of the outlet nozzle 54 of the outlet pipe 52 are each fixed by a fastener fixedly installed on the base plate 1.

[0058] In this embodiment, the openings of the inlet pipe 51 connected to the controller 10 and the openings of the outlet pipe 52 connected to the controller 10 both face upwards.

[0059] Multiple plugs 6 are provided for connecting to low-voltage connectors, resolvers, etc., on the electronic controller 10. Plugs 6 are fixedly mounted on the base plate 1 and / or the insulating protective layer plate 2. Plugs 6 also connect to the detection circuit and system, connecting the low-voltage circuit inside the electronic controller 10 to the detection circuit and system. Plugs 6 and the low-voltage connectors of the electronic controller 10 are connected manually.

[0060] Positioning elements 7 are used to position the electronic controller 10, facilitating its quick and accurate placement on the tray device. At least two positioning elements 7 are provided. In this embodiment, the positioning element 7 is a column, with one end fixedly mounted on the base plate 1 and the other end extending upwards through the isolation and protective layer 2. The electronic controller 10 has corresponding grooves. When placing the electronic controller 10, the grooves on the electronic controller 10 are aligned with the respective columns, allowing each column to be inserted into its corresponding groove, thus accurately placing the electronic controller 10. In other words, the columns simultaneously serve to position and support the electronic controller 10.

[0061] It should be noted that the inlet nozzle 53 and the outlet nozzle 54 can also serve a positioning function.

[0062] The fixing member 8 is used to secure the electronic controller 10 placed on the tray device. In this embodiment, the fixing member 8 is a clamp, with two clamps. The bottom of the clamp is fixed to the base plate 1, and the upper end of the clamp passes through the isolation protective layer 2 or extends upward from the edge of the isolation protective layer 2. The clamp presses down on the electronic controller 10 and, with the cooperation of the column, fixes the electronic controller 10. The clamp can be a quick clamp from the prior art, which will not be described in detail here.

[0063] The three-phase wire 9 is used to connect the three-phase connection assembly 3 to an external three-phase power supply. Specifically, the three-phase wire 9 is fixed to the base plate 1 by a fastener. One end of the three-phase wire 9 can be connected to the external three-phase power supply, and the other end is connected to the lower end of the three first bent copper blocks 306 of the three-phase connection assembly 3 by wires.

[0064] In this embodiment, the base plate 1 has a square structure, with its four sides arranged clockwise as front, left, rear, and right. The components are arranged as follows: the three-phase connection assembly 3 is located at the front end of the base plate 1. The high-voltage DC connection assembly 4 is located in the middle of the base plate 1. The inlet nozzle 53 and outlet nozzle 54 are located between the three-phase connection assembly 3 and the high-voltage DC connection assembly 4. Each plug 6 is located at the left end of the isolation and protective layer 2. The openings of the inlet pipe 51 and outlet pipe 52, which connect to the external water source, both face rearward. The end of the three-phase wire 9, which connects to the external three-phase power supply, also faces rearward. The fixing member 8 is located at the left and / or right end of the base plate 1.

[0065] Based on the above arrangement, the operator operates from the front side of the tray device, and the components on the tray device are connected from the rear side to the circuitry and water supply of the detection system.

[0066] Based on the above structure, the working principle and process of this utility model are as follows:

[0067] First, place the controller 10 on the tray device, align the groove on the controller 10 with the positioning member 7, and insert the upper end of the positioning member 7 into the groove of the controller 10, thus placing the controller 10 into the target position. After the controller 10 is placed in the target position, the water inlet 53 and the water outlet 54 are aligned with and connected to the water inlet and outlet of the water passage on the controller 10, respectively.

[0068] Then, the electronic controller 10 is fixed using the fastener 8. After fixing, the connection between the inlet nozzle 53 and the outlet nozzle 54 and the corresponding pipe is sealed due to the flexible sealing rings on the inlet nozzle 53 and the outlet nozzle 54, preventing water leakage.

[0069] Next, connect the low-voltage connector on the controller 10 to each plug 6.

[0070] Finally, turn the handles of the three-phase connection assembly 3 and the high-voltage DC connection assembly 4 to complete the electrical connection between the controller 10 and the detection system. The entire process takes less than 20 seconds, compared to several minutes in the traditional method, greatly shortening the pre-test connection time and improving production efficiency.

[0071] It should be noted that for the three-phase connection assembly 3, the first movable plate 302 is adjusted beforehand according to the size and model of the controller 10 to be tested, so that the first movable plate 302 moves along the first horizontal linear guide rail 310 to the set position and is then fixed. Thus, when the controller 10 is placed in the target position, the three-phase connector on the controller 10 is precisely located between the upper ends of the first lower support block 304 and the three first bent copper blocks 306. After operating the first handle assembly 308, the first upper support block 305 and the first bent copper blocks 306 descend as a whole until the upper ends of the three first bent copper blocks 306 respectively contact the three-phase connector on the controller 10. The three-phase connector of the controller 10 is clamped between the upper ends of the first bent copper blocks 306 and the first lower support block 304, while the lower ends of the three first bent copper blocks 306 are connected to the three-phase wires 9, thus connecting the controller 10 to the three-phase power supply. Therefore, the first bent copper blocks 306 are L-shaped to facilitate the above connection.

[0072] Similarly, for the high-voltage DC connection assembly 4, the second movable plate 402 is adjusted beforehand according to the size and model of the controller 10 to be tested, so that the second movable plate 402 moves along the second horizontal linear guide rail 410 to the set position and is then fixed. Thus, when the controller 10 is placed in the target position, the high-voltage DC connector on the controller 10 is exactly below the second bent copper block 406. After operating the second handle assembly 408, the mounting block 404 and the second bent copper block 406 descend as a whole until the upper end of the second bent copper block 406 contacts the high-voltage DC connector on the controller 10, thereby connecting the controller 10 to the high-voltage test circuit.

[0073] After the test is completed, reverse the first handle assembly 308 and the second handle assembly 408 to separate the second bent copper block 406 and the first bent copper block 306 from the controller, and then disconnect the low-voltage connector.

[0074] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of this utility model in detail, and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of this utility model shall fall within the scope of protection of this utility model.
