Description

Technical Field

[0001] The utility model belongs to the technical field of automobile testing and relates to a cable fixing bracket for motor testing. Background Art

[0002] During the development and testing of automotive power motors, the motors are installed on a laboratory test bench to verify performance and reliability. Testing requirements necessitate installing sensors on the motor's three-phase high-voltage wiring to measure electrical power parameters. The existing three-phase high-voltage wiring arrangement lacks space for sensor installation, so the original three-phase high-voltage terminal block cannot be used in its original configuration. An external high-voltage wiring harness extension is required to accommodate the sensor measurements. This testing configuration changes the existing wiring arrangement. The original connection had its own fixed points at each end, with the terminals connected by bolts and nuts. However, the extended wiring harness applies the weight of the harness itself to the three-phase terminals, increasing the torque load on the terminal bolts. The motor's continuous high speed and high torque output generate vibrations of varying frequencies, and the temperature of the high-voltage terminals changes after current flows through them. This reduces the stability of the high-voltage terminals during continuous motor operation testing. The connection between the three-phase terminals and the high-voltage extension cables is prone to loosening, resulting in a reduced contact surface, increased resistance, increased local current flow, and a sharp rise in temperature, potentially posing a fire hazard.

[0003] To solve the above problems, a cable bracket is needed to fix the three high-voltage wires of the motor to improve stability, ensure test safety, and improve test data accuracy. Utility Model Content

The support assembly 2 cooperates with the fixing panel 1 to fix the cables, better simulating the state of the cables when the motor is actually running, making the test results more accurate.

[0028] In this embodiment, the support assembly 2 includes a first leg 5 and a second leg 7 connected to each other. The first leg 5 is connected to the fixed panel 1 in a manner parallel to the XY plane, and the second leg 7 is connected to the first leg 5 in a manner that allows movement in the Z direction and along the length of the first leg 5. In this embodiment, the first leg 5 is configured to swing within the XY plane. In this embodiment, the fixed panel 1 is mounted with a fixed frame 4, which is arranged parallel to the XY plane. The first leg 5 is hinged to the fixed frame 4. The multi-degree-of-freedom adjustment of the fixed panel 1 in the present embodiment in the X, Y, and Z directions is achieved through the support assembly 2. The swing of the first leg 5 and the movement of the second leg 7 along the length direction of the first leg 5 enable the fixed panel 1 to have multiple adjustment capabilities in the XY plane, while the movement of the second leg 7 in the Z direction realizes the adjustment function of the fixed panel 1 in the Z direction, and the adjustment of the Z-direction height is to achieve a relatively horizontal state of the wiring harness end face; the adjustable Z-direction height can also adapt to motors with non-horizontal fulcrum mounting holes, ensuring the horizontal force state of the high-voltage wiring harness support point under different motor states. The support assembly 2 in the present embodiment is installed on the electric control mounting fulcrum or suspension mounting hole position on the motor product. The preset position of the present embodiment is the electric control mounting fulcrum or suspension mounting hole position. The overall bracket has adjustable X / Y / Z three-dimensional spatial distance, which is suitable for the fixed hole positions of motor products with different design sizes; the flexible fulcrum adjustment method has strong adaptability.

[0029] In this embodiment, the support assembly 2 further includes a connecting leg, through which the first leg 5 and the second leg 7 are connected. In this embodiment, the connecting leg has a first connecting section 8 and a second connecting section 9 that are perpendicular to each other. The first connecting section 8 is slidably connected to the first leg 5, and the second leg 7 is slidably connected to the second connecting section 9. In this embodiment, the first leg 5 is provided with a first slide groove 501 and a first limiting column, the first slide groove 501 is arranged along the length direction of the first leg 5, the first connecting section 8 is provided with a first intermediate slide groove 801 and a first intermediate limiting column, the first intermediate slide groove 801 is arranged along the length direction of the first connecting section 8; the first limiting column can be limited and slidably inserted in the first intermediate slide groove 801, and the first intermediate limiting column can be limited and slidably inserted in the first slide groove 501; the second leg 7 is provided with a second slide groove 701 and a second limiting column, the second slide groove 701 is arranged along the length direction of the second leg 7, the second connecting section 9 is provided with a second intermediate slide groove 901 and a second intermediate limiting column, the second intermediate slide groove 901 is arranged along the length direction of the second connecting section 9; the second limiting column can be limited and slidably inserted in the second intermediate slide groove 901, and the second intermediate limiting column can be limited and slidably inserted in the second slide groove 701. In this embodiment, the first leg 5 and the second leg 7 are connected by the middle leg 6 in an "L"-shaped structure, and the first leg 5 and the middle leg 6, as well as the second leg 7 and the middle leg 6, are all connected by adjustable sliding connection by inserting a limit column into a slide groove, so as to ensure the multi-degree-of-freedom adjustment function of the fixed panel 1. At the same time, whether it is the connection between the first leg 5 and the first connecting section 8, or the connection between the second leg 7 and the second connecting section 9, it is a two-way limit connection. Taking the connection between the first leg 5 and the first connecting section 8 as an example, the first limit column is slidably inserted into the first middle slide groove 801, which is the first sliding limit, and the first middle limit column is slidably inserted into the first slide groove 501, which is the second sliding limit. The double limit ensures the reliability of the connection and improves the smoothness of the sliding adjustment. In this embodiment, the first limit column, the first intermediate limit column, the second limit column and the second limit column adopt a detachable structure, that is, the corresponding limit columns can be disassembled and assembled on the corresponding legs. Taking the first leg 5 as an example, as shown in the figure, the first leg 5 is provided with a first slide groove 501 and a through hole as a first mounting hole 502 for mounting the first limit column. The first limit column uses fastening connectors such as bolts and nuts (not marked in the drawings), which realizes sliding connection and can also realize locking after adjustment.Correspondingly, the first intermediate limit column, the second limit column and the second limit column also use fastening connectors such as bolts and nuts. At the same time, the intermediate support leg 6 is provided with two through holes, the first intermediate mounting hole 802 and the second intermediate mounting hole 902, and the second support leg 7 is provided with a through hole, the second mounting hole 702, for correspondingly installing the first intermediate limit column, the second limit column and the second limit column. This is understandable to technicians in this technical field and will not be elaborated here.

[0030] In this embodiment, the second leg 7 is provided with a foot 703, which allows the second leg 7 to be removably mounted in a predetermined position. As shown in the figure, each second leg 7 is provided with a foot 703, which is provided with a through hole to accommodate motor products with different threaded hole sizes. The entire bracket is fixed and installed using bolts, which facilitates assembly and disassembly and provides good stability. Furthermore, to enhance structural stability, a reinforcing rib 704 is provided between the foot 703 and the second leg 7.

[0031] In this embodiment, the fixed frame 4 is provided with at least two hinge holes 401, and the two hinge holes 401 are provided at both ends of the fixed frame along the X direction, and any hinge hole 401 is hinged to at least two of the first legs 5. As shown in the figure, in this embodiment, the fixed frame 4 is a rectangular frame structure, and is provided with two hinge holes 401. The two hinge holes 401 are located on the beam of the fixed frame 4 on the side away from the fixed panel 1 in the Y direction, and are located at both ends of the beam in the X direction. That is, each hinge hole 401 is correspondingly installed with two sets of support assemblies 2. This arrangement makes the adjustment of each support assembly 2 more flexible, and the adjustment range of each support assembly 2 is larger. At the same time, there is no need to set more installation points on the frame to install the support assembly 2, making the overall structure more complete, the structural strength higher, and the processing simpler.

[0032] In this embodiment, the fixing member 3 is an arc-shaped cable clamp, and at least three of them are provided. As shown in the figure, nine fixing members 3 are provided in this embodiment, arranged in rows, with three fixing members 3 in each row and column. These fixing members 3 correspond to the three phases of the motor, with each phase secured by three fixing members 3. The fixing members 3 are arc-shaped cable clamps that form a wraparound clamp around the cable. Made of rubber, the fixing members 3 offer insulation and are suitable for securing high-voltage wiring harnesses. The rubber material is flexible and adapts well to the varying angles and surface roughness of the cable during the wraparound clamping operation, protecting the cable and ensuring good securement. The outer ring of the rubber interlayer of the fixing members 3 contains an electromagnetic shielding layer, isolating electromagnetic interference between the bracket and the cable. This further reduces the possibility of electromagnetic interference between the voltage and current signals within the cable and the metal structure of the bracket, thereby reproducing the true operating state of the measured product and improving measurement accuracy.
