Description
Technical Field
[0001] This utility model relates to the field of positioning tooling, specifically to a testing and docking tooling for an automotive motor controller. Background Technology
[0002] The automotive motor controller is a key component in electric vehicles (EVs) or hybrid electric vehicles (HEVs), primarily used to control the operation of the electric motor. To ensure the good performance of the automotive motor controller, after assembly, it needs to be connected to testing equipment to simulate its performance under different operating conditions for a certain period of time. Real-time data acquisition of the motor controller's current and voltage is performed to trigger an alarm when the current exceeds a set threshold. Before testing, the testing equipment needs to be connected to the motor controller. Specifically, workers attach the three-phase wiring harness of the testing equipment to the three-phase copper busbars of the motor controller, then insert screws into the connection holes and tighten them to prevent the wiring harness from slipping. This testing method causes stress damage to the three-phase copper busbars of the motor controller under test, and is time-consuming and inefficient. Furthermore, after prolonged testing, the three-phase copper busbars of the motor controller are prone to overheating due to poor contact, potentially burning out. Summary of the Invention
[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a test docking fixture for automotive motor controllers, which solves the problems of inconvenient copper busbar alignment during the test connection of existing motor controllers, and the copper busbars burning out due to temperature rise after long-term testing.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A testing and docking fixture for an automotive motor controller is installed on or beside a test bench of a testing device. It includes an insulating body and three detachable conductive terminals installed within the insulating body. The three conductive terminals are spaced apart, and each conductive terminal has a first connector and a second connector at its left and right ends, respectively. The first connector is used for electrical connection to the test lead of the current monitoring device of the testing device, and the second connector is used for electrical connection to the connecting lead of the temperature sensor on the testing device. A conductive copper busbar extends upward from the center of each conductive terminal, penetrating the upper surface of the insulating body. The sides of the conductive copper busbar are on the same plane, and each conductive copper busbar has a docking through hole for connecting to the three-phase copper busbar of the motor controller under test. A sliding mechanism is provided at the lower end of the insulating body, allowing the insulating body to slide along the length of the conductive terminals under external force, so that the conductive copper busbar corresponds and abuts against the three-phase copper busbar of the motor controller under test. In this way, when testing the motor controller, the motor controller under test is first hoisted above the testing equipment, and the docking fixture is installed next to the test bench of the testing equipment. Then, the test lead used to monitor the real-time current on the testing equipment is electrically connected to the first connector of the conductive terminal, and the connecting lead of the temperature sensor on the testing equipment is connected to the second connector of the conductive terminal. After the first and second connectors are connected, the hoisting equipment is controlled to lower the motor controller. After it is lowered into place, the insulating body is pushed towards the three-phase copper busbars on the motor controller, so that the three conductive copper busbars on the insulating body correspond one-to-one with the three-phase copper busbars on the motor controller and are tightly attached. Then, the three-phase copper busbars and the conductive copper busbars are connected and fixed with conductive bolts, thus completing the test connection. After the connection is completed, the testing equipment is started to monitor the current and temperature of the motor controller to monitor the current and temperature of the motor controller during simulated operation. At the same time, the temperature monitoring determines the real-time temperature of the three-phase copper busbars in the motor controller to prevent the three-phase copper busbars from burning out due to overheating. The conductive terminals on the insulating body can be connected to the corresponding wires on the testing equipment to realize real-time detection of the temperature and current values of the three-phase copper busbar. The spacing of the conductive copper busbar is the same as that of the three-phase copper busbar on the motor controller. When connecting with the three-phase copper busbar, the insulating body can be quickly aligned with the three-phase copper busbar by moving, and then fixed together by conductive bolts after alignment, making the connection quick and convenient.
[0005] Furthermore, the conductive terminal and the conductive copper busbar are integrally formed and made of copper. A wire end fixing hole is provided at the corresponding position between the conductive terminal and the first connector, and this wire end fixing hole is vertically positioned. A wire end fixing hole is also provided at the corresponding position between the conductive terminal and the second connector, along the length of the conductive terminal. Thus, the conductive terminal and the conductive copper busbar are integrally formed, resulting in a stable structure and stable conductivity. The wire end fixing hole on the conductive terminal allows the wire end of the test current test device to be placed in the fixing hole, and then fixed to the first connector of the conductive terminal with bolts. Similarly, after the end of the temperature sensor's connecting wire is aligned with the wire end fixing hole, the connecting wire is electrically connected to the second connector with bolts. This configuration allows for quick electrical connection between the conductive terminal and the wires on the test device.
[0006] Furthermore, the insulating body includes an insulating base and an insulating top cover detachably mounted on the insulating base. The insulating base has three U-shaped grooves for assembling conductive terminals. On the side of the insulating top cover corresponding to the second connector, three positioning holes are spaced apart, and on the opposite side of the positioning holes are three positioning notches. Between each positioning hole and notch is a copper busbar through-hole for the conductive copper busbar to pass through. The conductive terminal is placed in the U-shaped groove and, after being passed through by positioning bolts, is threadedly fixed to the insulating base. Thus, the insulating body is made of insulating material and will not interfere with current during application. When installing and fixing the conductive terminals and conductive copper busbars, first open the insulating top cover, then place each conductive terminal one by one into the corresponding U-shaped groove, then fix the conductive terminals with positioning bolts. Finally, align the copper busbar through-holes on the insulating top cover with the conductive copper busbars, and then fix the insulating top cover to the insulating base. This design facilitates the installation and positioning of the conductive terminals. Simultaneously, the position corresponding to the U-shaped groove exposes the second connector, facilitating the connection between the wire and the conductive terminal. The positioning holes provided on the insulating cover facilitate the insertion of tools when disassembling and replacing conductive terminals, while the positioning notches facilitate the installation of wires and the removal of positioning bolts.
[0007] Furthermore, the width of the U-shaped groove is greater than the width of the conductive terminal, and a vertical hole is provided on the conductive terminal for the positioning bolt to pass through, the diameter of which is greater than the diameter of the positioning bolt. Thus, when there is a positional deviation between the three-phase copper busbar and the conductive copper busbar, the conductive terminal and the conductive copper busbar have a certain displacement space, allowing for fine-tuning of their installation position.
[0008] Furthermore, two sliders with guide grooves are spaced apart on the lower end face of the insulating base, and a guide rail that mates with the guide groove is provided under each slider. Both the sliders and the guide rails are arranged along the length direction of the conductive terminal. In this way, the sliders and guide rails form the sliding mechanism. When the insulating body moves under the action of external force, the sliders can move along the length direction of the guide rails, guiding the movement of the insulating body.
[0009] Furthermore, a connecting plate detachably connected to the insulating body is provided on one side of the insulating body. A vertical plate is provided on the side of the connecting plate, and a pull rod is fitted onto the vertical plate, the pull rod being parallel to the conductive terminal. A mounting base is provided on the side of the insulating body near the second connector. After the pull rod passes through the mounting base, it is rotatably connected to an adapter arm. The adapter arm is V-shaped, with its end rotatably connected to a control handle via a rotating shaft. Both sides of the adapter arm face the insulating body, forming a locking space between the two arms that mates with the outer side of the rotating end of the control handle. When the control handle rotates a certain angle towards the insulating body under external force, the adapter arm drives the pull rod to move towards the adapter arm until the rotating end of the control handle is locked and positioned within the locking space of the adapter arm. In this way, the connecting plate can pull the connecting plate and the insulating body together after the pull rod moves axially. When the adapter arm, rotatably connected to the end of the pull rod, rotates under external force, it drives the pull rod to move axially. That is, when the control handle is turned, the adapter arm rotates accordingly. After rotating to a certain angle, the rotating end of the handle is locked between the two arms of the adapter arm, locking the control handle in place and preventing it from rotating further. This, in turn, prevents the adapter arm and the pull rod connected to the adapter arm from moving, thus achieving positioning and ultimately positioning the insulating body. This setup allows for quick and convenient operation by simply rotating the control handle to pull and position the insulating body.
[0010] Furthermore, the connecting plate is Z-shaped, and its upper end is fixed to the insulating body by fastening bolts; the upright plate is integrally formed with the connecting plate, and is a bent plate with the lower end of the connecting plate bent upwards. In this way, the upper end of the connecting plate is fixedly connected to the insulating cover of the insulating body, and the lower end is bent upwards to form an upright plate for the upright to be inserted, and the overall structure is simple and reliable.
[0011] Furthermore, the mounting base is L-shaped and consists of a base plate and a vertical mounting plate; a guide tube for threading the tie rod is provided on the vertical mounting plate. In this way, the guide tube on the mounting base allows the tie rod to pass through, forming a two-point support for the tie rod between the guide tube and the vertical plate of the linkage plate, and at the same time, it can also guide the movement direction of the vertical rod.

[0015] To monitor the performance of a motor controller, it is necessary to simulate its operating environment using testing equipment. After connecting the test equipment to the equipment, the performance of each component on the motor controller can be monitored in real time to achieve aging testing. The three-phase copper busbar is a critical component connecting the motor and the motor controller. Therefore, during testing, the three-phase copper busbar needs to be electrically connected to the testing equipment, and its temperature and current must be monitored in real time to observe its performance under different usage periods. Simultaneously, the temperature monitoring of the three-phase copper busbar can also be connected to an alarm controller on the testing equipment to issue an alarm when a set temperature threshold is exceeded, preventing the three-phase copper busbar from burning out during testing, causing losses, and affecting the test results. However, existing testing equipment cannot quickly align and locate the three-phase copper busbar during connection to the motor controller, and it cannot perform real-time temperature monitoring of the three-phase copper busbar.
[0016] For the reasons mentioned above, the automotive motor controller test docking fixture (such as...) provided in this embodiment... Figures 1-4As shown, the test docking fixture is installed on or beside the test platform of the test equipment. It includes an insulating body 1 and three detachable conductive terminals 2 installed inside the insulating body 1. The three conductive terminals 2 are spaced apart, and each conductive terminal 2 has a first connector 21 and a second connector 22 at its left and right ends, respectively. The first connector 21 is used to electrically connect with the test wire of the current monitoring of the test equipment, and the second connector 22 is used to electrically connect with the connecting wire of the temperature sensor on the test equipment. A conductive copper busbar 3 extends upward from the middle of each conductive terminal 2 and penetrates the upper surface of the insulating body 1. The sides of the conductive copper busbar 3 are on the same plane, and each conductive copper busbar 3 has a docking through hole 31 for connecting with the three-phase copper busbar 41 of the motor controller under test. A sliding mechanism is provided at the lower end of the insulating body 1 to connect with it. Under the action of external force, the insulating body 1 can slide along the length direction of the conductive terminal 2, so that the conductive copper busbar 3 corresponds one-to-one with the three-phase copper busbar 41 on the motor controller under test and is in contact with it. When testing the motor controller 4, the motor controller under test is first hoisted above the testing equipment. The docking fixture is installed next to the test bench of the testing equipment. Then, the test wire used to monitor the real-time current on the testing equipment is electrically connected to the first connector 21 of the conductive terminal 2, and the connecting wire of the temperature sensor on the testing equipment is connected to the second connector 22 of the conductive terminal 2. After the first connector 21 and the second connector 22 are connected, the hoisting equipment is controlled to lower the motor controller. After it is lowered into place, the insulating body 1 is pushed towards the three-phase copper busbar 41 on the motor controller, so that the three conductive copper busbars 3 on the insulating body 1 correspond one-to-one with the three-phase copper busbars 41 on the motor controller and are tightly attached. Then, the three-phase copper busbars 41 and the conductive copper busbars 3 are connected and fixed with conductive bolts, thus completing the test connection. After the connection is completed, the testing equipment is started to monitor the current and temperature of the motor controller to monitor the current and temperature of the motor controller during simulated operation. At the same time, the real-time temperature of the three-phase copper busbar 41 in the motor controller is determined by temperature monitoring to prevent the three-phase copper busbar 41 from burning out due to overheating. The conductive terminals 2 on the insulating body 1 can be connected to the corresponding wires on the test equipment to realize the real-time detection of the temperature and current values of the three-phase copper busbar 41. The spacing of the conductive copper busbar 3 is the same as that of the three-phase copper busbar 41 on the motor controller. When connecting with the three-phase copper busbar, the insulating body 1 can be quickly aligned with the three-phase copper busbar 41 by moving, and then fixed together by conductive bolts after alignment. The connection is quick and convenient. This sliding and docking method will not make hard contact with the conductive copper busbar 3 after the motor controller moves down, thus avoiding damage to the copper busbar caused by hard contact.
[0017] like Figure 5As shown, the conductive terminal 2 and the conductive copper busbar 3 are integrally formed and made of copper. A wire end fixing hole 25 is provided at the corresponding position between the conductive terminal 2 and the first connector 21, and the wire end fixing hole 25 is vertically arranged. A wire end fixing hole 26 is provided along the length direction of the conductive terminal 2 at the corresponding position between the conductive terminal 2 and the second connector 22. Thus, the conductive terminal 2 and the conductive copper busbar 3 are integrally formed, resulting in a stable structure and stable conductivity. The wire end fixing hole 25 on the conductive terminal 2 allows the wire end of the test current on the testing equipment to be placed in the wire end fixing hole 25, and then the wire end is fixed to the first connector 21 of the conductive terminal 2 by bolts. Similarly, after the end of the connecting wire of the temperature sensor is attached to the wire end fixing hole 26, the connecting wire is electrically connected to the second connector 22 by bolts. This arrangement allows for quick electrical connection between the conductive terminal 2 and the wires on the testing equipment.
[0018] like Figure 6 As shown, the insulating body 1 includes an insulating base 11 and an insulating cover 12 detachably mounted on the insulating base 11 (in this embodiment, the insulating body 1 is made of rubber, plastic, or resin insulating material). The insulating base 11 has three U-shaped grooves 111 for assembling conductive terminals 2. The insulating cover 12 has three positioning holes 121 spaced apart on one side corresponding to the second connector 22, and three positioning notches 122 on the opposite side of the positioning holes 121. Between each positioning hole 121 and positioning notch 122, there is a copper busbar through hole 123 for the conductive copper busbar 3 to pass through. The conductive terminal 2 is placed in the U-shaped groove 111, and after passing through the conductive terminal 2 with a positioning bolt, it is threadedly connected and fixed to the insulating base 11. To facilitate the fixing of the conductive terminal, a first fixing hole 23 and a second fixing hole 24 are respectively provided at the first connector 21 and the second connector 22. When fixing the conductive terminal 2, the bolt is directly passed through the first fixing hole and the second fixing hole, and then threadedly engaged with the threaded hole on the insulating base 11 for fixation. Thus, the insulating body 1 is made of insulating material and will not interfere with the current during application. When installing and fixing the conductive terminals 2 and the conductive copper busbars 3, first open the insulating cover 12, then place each conductive terminal 2 into the corresponding U-shaped groove 111, and then fix the conductive terminals 2 with positioning bolts. Finally, after aligning the copper busbar through holes 123 on the insulating cover 12 with the conductive copper busbars 3, fix the insulating cover 12 onto the insulating base 11. This arrangement facilitates the installation and positioning of the conductive terminals 2. Simultaneously, the position corresponding to the U-shaped groove 111 exposes the second connector 22, facilitating the connection of the wire to the conductive terminal 2. The positioning through holes 121 on the insulating cover 12 allow tools to be inserted when disassembling and replacing the conductive terminals 2, and the positioning notches 122 facilitate the installation of wires and the removal of positioning bolts.
[0019] To achieve rapid alignment of the conductive copper busbar 3 and the three-phase copper busbar 41, the installation positions of the motor controller 4 and the tooling are fixed based on the busbar positions during installation. However, slight errors are inevitable in actual implementation. Therefore, the position of the conductive copper busbar 3 needs to be adjustable within tolerance limits according to the actual situation. To achieve adjustment of the conductive copper busbar 3, the width of the U-shaped groove 111 is greater than the width of the conductive terminal 2, and the width of the copper busbar through hole 123 is greater than the width of the conductive copper busbar 3. A vertical hole for the positioning bolt to pass through is provided on the conductive terminal 2, and the diameter of the vertical hole is greater than the diameter of the positioning bolt. In this way, when there is a positional deviation between the three-phase copper busbar 41 and the conductive copper busbar 3, the conductive terminal 2 and the conductive copper busbar 3 have a certain displacement space, allowing for fine-tuning of their installation positions.
[0020] If the path of movement of the insulating body 1 is not fixed, the position of the conductive copper busbar 3 may deviate during movement. To avoid this problem, two sliders 13 with guide grooves are provided at intervals on the lower end face of the insulating base 11. Each slider 13 is provided with a guide rail 14 that cooperates with the guide groove. Both the sliders 13 and the guide rails 14 are arranged along the length direction of the conductive terminal 2. In this way, the sliders 13 and the guide rails 14 form the sliding mechanism. When the insulating body 1 moves under the action of external force, the sliders 13 can move along the length direction of the guide rails 14 to guide the movement of the insulating body 1.
[0021] Specifically, in this embodiment, the sliding and positioning of the insulating body 1 is achieved through the following structure: a connecting plate 5 is provided on one side of the insulating body 1, which is detachably connected to the insulating body 1; a vertical plate 51 is provided on the side of the connecting plate 5; a pull rod 6 is sleeved on the vertical plate 51, and the pull rod 6 is arranged parallel to the conductive terminal 2; a mounting base 9 is provided on the side of the insulating body 1 near the second connector 22; after the pull rod 6 passes through the mounting base 9, it is rotatably connected to a transition arm 7; the transition arm 7 is V-shaped, and its end is rotatably connected to a control handle 8 through a rotating shaft 91; and both sides of the transition arm 7 are arranged towards the insulating body 1, forming a clamping space between the two arms that cooperates with the outer side of the rotating end of the control handle 8; when the control handle 8 rotates a certain angle towards the insulating body 1 under the action of external force, the transition arm 7 drives the pull rod 6 to move towards the transition arm 7 until the rotating end of the control handle 8 is placed in the clamping space of the transition arm 7 and clamped and positioned. In this way, the connecting plate 5 can be pulled together with the insulating body 1 after the pull rod 6 moves axially. The adapter arm 7, rotatably connected to the end of the pull rod 6, rotates under external force, thus driving the pull rod 6 to move axially. That is, when the control handle 8 is rotated, the adapter arm 7 will rotate accordingly. After rotating to a certain angle, the rotating end of the control handle is locked between the two arms of the adapter arm 7, locking and positioning the control handle 8, preventing it from rotating further. This further prevents the adapter arm 7 connected to the control handle 8 and the pull rod 6 connected to the adapter arm 7 from moving, achieving positioning and ultimately positioning the insulating body 1. This setup allows for pulling and positioning of the insulating body 1 simply by rotating the control handle 8, making operation quick and convenient.
[0022] Furthermore, the connecting plate 5 is Z-shaped, and its upper end is fixed to the insulating body 1 by fastening bolts; the upright plate 51 is integrally formed with the connecting plate 5, and is a bent plate with the lower end of the connecting plate 5 bent upward. In this way, the upper end of the connecting plate 5 is fixedly connected to the insulating cover 12 of the insulating body 1, and the lower end is bent upward to form the upright plate 51 for the upright to pass through, and the overall structure is simple and reliable.
[0023] Furthermore, the mounting base 9 is L-shaped and consists of a base plate and a vertical mounting plate. A guide cylinder 92 for the pull rod 6 to pass through is provided on the vertical mounting plate. The mounting base 9 is detachably mounted on a pad. A through hole for the pull rod 6 to pass through is provided on the vertical plate 51. A limiting nut is fitted at the end of the pull rod 6 near the adapter arm 7, and a plug is fixed at the end of the pull rod 6 away from the vertical plate 51. The maximum movement distance of the pull rod 6 is the length between the limiting nut and the plug. Thus, the guide cylinder 92 on the mounting base 9 allows the pull rod 6 to pass through, forming a two-point support for the pull rod 6 between the guide cylinder 9 and the vertical plate 51 of the connecting plate 5. Simultaneously, it guides the movement direction of the vertical rod.
[0024] In practical implementation, the adapter arm 7 and control handle 8 can be removed, and an adjusting nut can be directly installed on the mounting base 9. An external thread that mates with the adjusting nut can be provided on the pull rod 6. The movement and positioning of the pull rod 6 and the rotating plate can be achieved by rotating the adjusting nut to drive the pull rod 6 to move axially and position it. This method is more cumbersome to operate than the method using the control handle 8 and adapter arm 7.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
