Description

Technical Field

[0001] This utility model relates to a radar module testing device, belonging to the field of radar testing technology. Background Technology

[0002] As radar detection range increases, so does the corresponding radar power, the number of internal channels, and the number of internal modules. Before being sealed, radar modules must undergo testing and verification of various performance parameters. Current testing equipment has the following problems:

[0003] 1. There are differences between the test results before and after sealing, meaning that the performance parameters tested after sealing do not meet the standards, thus requiring frequent opening of the cover for maintenance. This not only easily leads to uncertain damage to the inside of the module, but also greatly affects the speed of module testing and maintenance, making the operation troublesome and costly.

[0004] 2. Due to the high power consumption and heat generation of the internal modules of the radar, timely heat dissipation is required during testing to avoid affecting the working performance of the modules. However, existing devices are difficult to effectively meet this requirement. Utility Model Content

[0005] The present invention aims to provide a radar module testing device to solve the problem that the test results before the radar module is sealed are not as accurate as the test results after sealing, thereby improving the efficiency of module performance testing and reducing production and labor costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A radar module testing device includes an installation platform, on which an electrical control unit, a TR module connected to the electrical control unit, and a power divider module connected to the TR module are provided. The installation platform is provided with a support frame, on which a clamping block is detachably fixedly connected, and the end of the clamping block contacts the TR module.

[0008] During testing, the clamping block is brought into contact with and pressed against the TR module to simulate the state of the radar module after it is covered. Performance testing is then conducted via the electrical control unit, TR module, and power divider module. This radar module testing device, by incorporating the clamping block that contacts the TR module, solves the problem of inaccurate test results before and after radar module coverage, thus improving the efficiency of module performance testing and reducing production and labor costs.

[0009] Furthermore, the end of the clamping block is provided with a pressure sensor connected to the electrical control unit, and the pressure sensor is in contact with the TR module.

[0010] Furthermore, to facilitate quick disassembly of the clamping block, a spring is provided between the support frame and the clamping block.

[0011] Furthermore, the clamping block includes a head and a rod body that are perpendicularly connected to each other, the spring is connected between the head and the support frame, and the rod body is detachably fixedly connected to the support frame.

[0012] Furthermore, the clamping block is provided with graduations.

[0013] Furthermore, in order to prevent damage to the surface of the TR module, the TR module is provided with a tooling block, and the end of the clamping block contacts the tooling block.

[0014] Furthermore, the clamping block is threadedly connected to the support frame.

[0015] Furthermore, the bottom of the mounting platform is provided with several spaced-apart heat sinks and axial fans.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. The radar module testing device of this utility model simulates the state of the radar module after it is covered by setting a clamping block that contacts the TR module. This solves the problem that the test results before the radar module is covered are not accurate enough compared with the test results after the cover is covered. It reduces the number of times the cover needs to be opened for maintenance due to substandard performance parameters after the cover is covered, improves the efficiency of module performance testing and the convenience of operation, and reduces production costs and labor costs.

[0018] 2. The radar module testing device of this utility model can record and simulate the pressure value corresponding to the radar module after it is sealed by setting a pressure sensor at the end of the clamping block that contacts the TR module. This further improves the accuracy of the test results, reduces the number of times the module needs to be opened for maintenance due to substandard performance parameters after sealing, improves the efficiency of module performance testing and ease of operation, and reduces production and labor costs.

[0019] 3. The radar module testing device of this utility model, by setting a spring between the support frame and the clamping block, allows the TR module to be easily disassembled after the test is completed, which improves the ease of operation, increases production efficiency, and saves time and effort.

[0020] 4. The radar module testing device of this utility model can prevent damage to the surface of the TR module by setting a tooling pressure block on the TR module that contacts the end of the pressure block, which not only improves the service life of the radar module, but also reduces the impact on the test results after the radar module is covered.

[0021] 5. The radar module testing device of this utility model can meet the heat dissipation requirements of the radar module by setting several spaced heat sinks and axial fans at the bottom of the mounting platform, and provides strong protection for the radar module.

[0022] 6.

It has a simple structure, is easy to manufacture and disassemble, and has low cost. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] See Figures 1 to 3 This embodiment provides a radar module testing device. The radar module testing device includes a mounting platform 1, an electrical control unit 2, a TR module 3, a power divider module 4, a tooling block 5, a support frame 6, a clamping block 7, a pressure sensor 8, and a spring 9.

[0029] The mounting platform 1 is a plate-like structure, on which the electrical control unit 2, TR module 3, power divider module 4, and support frame 6 are all fixedly mounted. The electrical control unit 2 includes a power module, a control module, and a digital display, used for power supply and control. The electrical control unit 2 is connected to the TR module 3 and pressure sensor 8 via cables. The TR module 3 is connected to the power divider module 4 via an SMP-KK quick-connect connector. A tooling block 5, plate-shaped, is installed in a slot above the TR module 3 to prevent damage to the surface of the TR module 3. The support frame 6 is located directly above the TR module 3 and the tooling block 5, and has a U-shaped structure. A clamping block 7 is T-shaped, consisting of a head and a rod connected perpendicularly to each other. The rod of the clamping block 7 is threaded to the support frame 6, and the bottom of the rod of the clamping block 7 is fixed to the pressure sensor 8. A spring 9 connects the head of the clamping block 7 to the upper surface of the support frame 6. Pressure sensor 8 contacts the tooling block 5 and is used to record the measured pressure value on the tooling block 5. Spring 9 is used to automatically lift the clamping block 7 and pressure sensor 8 after the clamping block 7 is loosened, so that the TR module 3 can be removed after the test is completed.

[0030] During testing, the clamping block 7 is adjusted up and down (by screwing it on or off), and the pressure sensor 8 measures the pressure on the tooling block 5. This quantitatively records the corresponding pressure after the TR module 3 is sealed, thereby improving the accuracy of the test results, reducing the number of times the cover needs to be opened for maintenance due to substandard performance parameters after sealing, improving the efficiency and ease of operation of module performance testing, simplifying the module debugging process, and reducing production and labor costs.

[0031] The process of using this device to test the module channel is as follows: The power module of the electrical control unit 2 supplies power to the TR module 3 through a cable. The TR module 3 is connected to an external signal source that provides the excitation signal. The power divider module 4 provides the local oscillator signal to the TR module 3. A spectrum analyzer is connected to the output port of the TR module 3 to measure the receiving gain and isolation of the TR module 3. The data read from the spectrum analyzer can be used to determine whether the receiving gain and isolation of the TR module 3 are qualified. If the gain is insufficient, the pressure on the tooling block 5 or the TR module 3 is increased or decreased by adjusting the clamping block 7 until the data meets the standard. The pressure value of the TR module 3 is recorded. This pressure value will be used for sealing and soldering when the module is sealed later. After the data meets the standard, the power is cut off, the power divider module 4 is disconnected, and the connection between the clamping block 7 and the support frame 6 is loosened. At this time, the spring 9 will lift the clamping block 7 and the pressure sensor 8. Then the cable is removed, and the tested TR module 3 can be taken out for replacement of the next batch of TR modules 3. After the replacement is completed, the same steps are repeated for testing.

[0032] During the test, in order to quickly dissipate heat from the module, several spaced heat sinks 10 and six axial fans 11 were installed at the bottom of the mounting platform 1.

[0033] In this embodiment, there are eight TR modules 3, arranged in a row on the mounting platform 1. There are two power divider modules 4, each of which distributes the signal to four TR modules 3. There are eight clamping blocks 7 and eight pressure sensors 8, corresponding to the eight TR modules 3. In this way, the radar module testing device can perform individual or batch testing on multiple modules, improving the testing speed of TR modules 3, meeting the testing requirements of radar, and saving labor and time costs.

[0034] In this embodiment, a scale can be set on the clamping block 7, so that the pressure value on the tooling clamping block 5 or TR module 3 can be intuitively understood or measured through the scale during implementation.

Unless otherwise specified, the embodiments and features described herein can be combined with each other.
