Description

Technical Field

[0001] This utility model relates to the technical field of millimeter-wave radar module voltage testing equipment, specifically a millimeter-wave radar module voltage testing device. Background Technology

[0002] When testing the voltage of a millimeter-wave radar module using a voltage testing fixture, the millimeter-wave radar module is first placed in the test slot. Then, the millimeter-wave radar module is pressed using the drive pressing handle, so that the voltage test point of the millimeter-wave radar module comes into contact with the probe electrically connected to the test control circuit board inside the test control box. Then, under the electrical conduction of the probe, the voltage of the millimeter-wave radar module is tested using the test control circuit board.

[0003] The existing voltage testing fixture connects the test slot and the test control box via multiple elastic telescopic sleeves. This serves two purposes: firstly, to provide movement space when pressing down on the millimeter-wave radar module, facilitating its placement and removal; and secondly, to ensure sufficient contact between the probe and the voltage test point of the millimeter-wave radar module. However, during prolonged testing, the springs within the elastic sleeves between the test slot and the test control box can become excessively deformed due to repeated pressing, reducing their elastic restoring force. This reduced force makes it difficult for the test slot to accurately reset, potentially leading to insufficient or excessive pressing of the millimeter-wave radar module. Consequently, the probe may fail to make sufficient contact with the test point of the millimeter-wave radar module, or it may make excessive contact, further reducing test accuracy or damaging the probe.

[0004] Therefore, a millimeter-wave radar module voltage testing device is urgently needed to solve the above problems. Utility Model Content

The first mounting plate is provided with multiple displays. A second mounting plate is slidably connected to the first mounting plate via two guide rods. A plurality of pressing posts are provided on the side of the second mounting plate near the test control box.

[0012] The four telescopic tubes have operating holes on their side walls, and operating plates are snapped into the four operating holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the design of a telescopic component, ensures convenient handling and sufficient contact with the probe during the voltage testing of millimeter-wave radar modules.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-7 The millimeter-wave radar module voltage testing device shown in the figure includes a test control box 101 and a first mounting plate 103 disposed on one side of the test control box 101. The first mounting plate 103 is provided with multiple displays 104. The first mounting plate 103 is slidably connected to a second mounting plate 105 via two guide rods. The second mounting plate 105 is provided with multiple pressing posts 106 on the side of the test control box 101 near the test control box 101. The second mounting plate 105 is provided with pressing handles 107 for driving each pressing post 106. It also includes a third mounting plate 2 disposed on the side of the test control box 101 near the first mounting plate 103. The third mounting plate 2 is provided with multiple probes 3. One end of each probe 3 is electrically connected to the test control circuit board inside the test control box 101. The side of the third mounting plate 2 away from the test control box 101 is connected to a test placement plate 4 via four telescopic components arranged symmetrically in pairs. The test placement plate 4 has two test slots 5.

[0026] The telescopic assembly includes a telescopic tube 601 fixedly connected to the side of the third mounting plate 2 near the test placement plate 4. A telescopic rod 602 is slidably connected to the telescopic tube 601. One end of the telescopic rod 602 is connected to the test placement plate 4, and the other end of the telescopic rod 602 is located inside the telescopic tube 601 and is fixedly connected to a telescopic plate 603. A telescopic spring 604 is connected to the side of the telescopic plate 603 away from the telescopic rod 602 through the mounting assembly. The telescopic tube 601 is provided with an adjustment assembly for adjusting the elastic force of the telescopic spring 604.

[0027] It should be noted that the telescopic component ensures convenient access and sufficient contact with probe 3 during the voltage test of the millimeter-wave radar module. Furthermore, the adjustment component, in conjunction with the rotating component, adjusts the compression of the telescopic spring 604 to regulate its elastic force. This maintains good elastic restoring force in the telescopic spring 604, reducing the risk of insufficient contact or excessive contact between probe 3 and the millimeter-wave radar module test point due to insufficient elastic force of the spring 604. This further ensures the accuracy of the millimeter-wave radar module voltage test.

[0028] Please see Figure 4The four telescopic rods 602 in the figure have scale lines 605 on their side walls;

[0029] It should be noted here that the setting of scale line 605 makes it easy to quickly identify the elastic restoring force of the extension spring 604.

[0030] Please see Figure 4 and Figure 5 The adjustment assembly shown in the figure includes an adjustment rod 701 fixedly connected between two inner walls of the telescopic tube 601, an adjustment plate 702 slidably connected to the adjustment rod 701, the other end of the telescopic spring 604 being connected to the adjustment plate 702 via an installation assembly, a threaded rod 703 rotatably connected between the two inner walls of the telescopic tube 601, the adjustment plate 702 being threadedly connected to the threaded rod 703, and the telescopic tube 601 being provided with a rotating assembly for rotating the threaded rod 703.

[0031] It should be noted here that the compression of the extension spring 604 can be changed by adjusting the settings of the components.

[0032] Please see Figure 4 and Figure 5 The rotating assembly shown in the figure includes a rotating rod 801 rotatably connected to the telescopic tube 601. One end of the rotating rod 801 is connected to a rotating ball 804, and the other end of the rotating rod 801 is located inside the telescopic tube 601 and is fixedly connected to a first bevel gear 802. A second bevel gear 803 is fixedly connected to the side wall of the threaded rod 703. The second bevel gear 803 and the first bevel gear 802 are meshed with each other.

[0033] It should be noted here that the rotating component facilitates the rotation of the threaded rod 703.

[0034] Working principle: When performing voltage testing on the millimeter-wave radar module, the module is first placed in the test slot 5 on the test placement plate 4. Then, by pressing the handle 107, the pressing posts 106 on the second mounting plate 105 move closer to the millimeter-wave radar module. When each pressing post 106 comes into contact with the module, the module moves closer to each probe 3 under the pushing force. When each probe 3 comes into contact with the voltage test point of the module, the test can be initiated by activating the control switch. The probes 3, electrically connected to the test control circuit board inside the test control box 101, then perform the test. Voltage testing of millimeter-wave radar modules is achieved, and the test results are displayed on the screen 104. This eliminates the need for soldering and assembly of the millimeter-wave radar module with other modules during testing. The probe 3 is electrically connected to the test control circuit board inside the test control box 101, enabling electrical connection with the test control circuit board, other test auxiliary modules, and limit switch modules inside the test control box 101. Two millimeter-wave radar modules can be measured simultaneously, or only one can be tested. This reduces the testing cost of millimeter-wave radar modules while improving the convenience and efficiency of testing.

[0035] Furthermore, during the process of pushing the millimeter-wave radar module closer to the probe 3, the telescopic spring 604 will be squeezed, causing the telescopic spring 604 to deform and generate elastic force. After the voltage test of the millimeter-wave radar module is completed, the pressing and pushing of the millimeter-wave radar module can be released. At this time, under the elastic action of the telescopic spring 604, the millimeter-wave radar module is pushed to separate from the probe 3, thus facilitating the removal of the millimeter-wave radar module.

[0036] Meanwhile, during multiple tests of the millimeter-wave radar module, the elastic restoring force of the telescopic spring 604 can be quickly identified by observing the scale line 605 on the telescopic rod 602. When the elastic restoring force of the telescopic spring 604 decreases, the threaded rod 703 is rotated by the rotating component. Under the threaded meshing transmission between the threaded rod 703 and the adjusting plate 702, and the guiding action of the adjusting rod 701, the adjusting plate 702 is pushed closer to the telescopic plate 603, thereby compressing the telescopic spring 604. By changing the amount of compression of the telescopic spring 604, its elastic force can be adjusted, thus ensuring that the telescopic spring 604 maintains good elastic restoring force. This reduces the risk that insufficient elastic force of the telescopic spring 604 may cause the probe 3 to fail to make sufficient contact with the test point of the millimeter-wave radar module or to make excessive contact, thereby further ensuring the accuracy of the voltage test of the millimeter-wave radar module.

[0037] Example 2

[0038] Please see Figures 5-7This embodiment further illustrates Example 1. The installation assembly shown in the figure includes a circular plate 901 fixedly connected to both ends of the telescopic spring 604. The circular plate 901 is detachably connected to the telescopic spring 604. A T-shaped plate 902 is fixedly connected to one side of the two circular plates 901 that is far apart from each other. The two T-shaped plates 902 are connected to the opposite sides of the two T-shaped plates 902 by a pressing assembly. The four mounting rods 904 have rounded corners at one end near the inner wall of the telescopic tube 601. A T-shaped hole 903 is opened on the opposite side of the telescopic plate 603 and the adjusting plate 702. An installation hole 905 is opened on the two inner walls opposite to the two T-shaped holes 903.

[0039] It should be noted here that the installation components facilitate the installation of the telescopic spring 604 inside the telescopic tube 601, thereby making it easy to replace the telescopic spring 604 when it reaches its limit of use.

[0040] Please see Figure 6 and Figure 7 The extrusion assembly shown in the figure includes an extrusion chamber 1001 opened in the T-shaped plate 902, an extrusion plate 1002 slidably connected to the extrusion chamber 1001, one end of the mounting rod 904 connected to the extrusion plate 1002, and an extrusion spring 1003 fixedly connected to the side of the extrusion plate 1002 away from the mounting rod 904, and the other end of the extrusion spring 1003 connected to the extrusion chamber 1001.

[0041] It should be noted here that the compression assembly is used to guide and reset the mounting rod 904.

[0042] Working principle: When the elasticity of the telescopic spring 604 reaches its limit, it needs to be replaced. When replacing the telescopic spring 604, first remove the operating plate 1102, and then insert your fingers into the telescopic tube 601 to pull the telescopic spring 604 or the circular plates 901 at both ends. Under the action of the pulling force, the telescopic spring 604 can be taken out from the telescopic tube 601.

[0043] After removing the telescopic spring 604 from the telescopic tube 601, the circular plates 901 at both ends of the telescopic spring 604 are disassembled. Then, the two ends of the new telescopic spring 604 are connected to the circular plates 901 respectively. After the new telescopic spring 604 is connected, the replaced telescopic spring 604 is reinstalled into the telescopic tube 601 under the guidance of the T-shaped plate 902 and the T-shaped hole 903. During the sliding process of the T-shaped plate 902 in the T-shaped hole 903, when the mounting rod 904 is engaged with the mounting hole 905, under the elastic action of the pressing component, the mounting rod 904 will be pushed into the mounting hole 905 and abut against the bottom wall of the mounting hole 905. Thus, the installation and fixation of the telescopic spring 604 is achieved through the abutment action of the mounting rod 904, thereby completing the replacement operation of the telescopic spring 604.

[0044] Example 3

[0045] Please see Figure 3 This embodiment is a further explanation of other embodiments. The four telescopic tubes 601 in the figure have operation holes 1101 on their side walls, and the four operation holes 1101 are snapped with operation plates 1102.

[0046] It should be noted here that the operation hole 1101 and the operation plate 1102 provide operating space for replacing the telescopic spring 604.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
