For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0063] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0064] refer to Figures 1 to 4 The present application provides an antenna waterproof test tool 1, including a fixture 2, a base 3, an external pipe 4 and a wire 5. The fixture 2 includes a height direction ( Figure 2 The mounting surface 20 and the connecting portion 21 are arranged opposite to each other (in the Z direction), and the extending direction of the mounting surface 20 ( Figure 2 The X direction is shown in the figure) and is inclined to the height direction, and the two are arranged at an acute angle α.

[0065] The mounting surface 20 is fitted and connected with the bottom surface 60 of the antenna 6. That is, the mounting surface 20 is completely fitted with the bottom surface 60 of the antenna 6, and the two have the same inclination direction or curvature. Exemplarily, the mounting surface 20 simulates the curved surface of the roof of the car for mounting the antenna 6 (for example, above the rear windshield on the top of the car), that is, the mounting surface 20 is a curved surface with a set curvature, so that the bottom surface 60 of the antenna 6 is better fitted and connected with the mounting surface 20, so as to obtain a more realistic test result.

[0066] Exemplarily, the mounting surface 20 is rectangular, with a length of 250 mm and a width of 90 mm, which is close to the size of the antenna 6 and is more convenient to use.

[0067] Exemplarily, the mounting surface 20 and the plane where the connecting portion 21 is located are arranged at an acute angle. Figure 2 The fixture 2 is trapezoidal in shape, but also roughly triangular in shape. The fixture 2 includes a first end 200 and a second end 201. The height direction of the first end 200 of the fixture 2 ( Figure 2 The length of the second end 201 in the Z direction is the smallest, and the length in the height direction of the second end 201 is the largest. Figure 2 The length of the fixture 2 in the height direction gradually decreases from the second end 201 to the first end 200 to simulate the slope of the roof where the antenna is installed.

[0068] The fixture 2 is provided with a through hole 22, and the through hole 22 passes through the mounting surface 20 and the connecting portion 21. Exemplarily, the through hole 22 is along the first direction ( Figure 2 The first direction is perpendicular to the extension direction of the mounting surface 20 ( Figure 2 X direction).

[0069] Optionally, the cross-section of the through hole 22 is rectangular and is located at the center of the fixture 2 .

[0070] Exemplarily, the material of the fixture 2 is 45 steel, which has high temperature resistance and is not easily deformed between -20°C and +400°C.

[0071] The base 3 is located below the fixture 2 and is sealed and connected to the connecting portion 21; the base 3 is provided with a receiving cavity 30, and the receiving cavity 30 is connected to the through hole 22. Exemplarily, the base 3 and the connecting portion 21 are sealed and connected to prevent liquid from flowing into the receiving cavity 30 and / or the through hole 22 from the connection between the base 3 and the connecting portion 21.

[0072] Exemplarily, the cross section of the accommodating cavity 30 is rectangular.

[0073] The external pipe 4 is located on the outer side wall 31 of the base 3, one end of the external pipe 4 is connected to the accommodating chamber 30, and the other end of the external pipe 4 extends outward to a device status monitoring system (not shown).

[0074] It should be noted that the length of the external pipeline 4 depends on the distance from the base 3 to the equipment status monitoring system, and this embodiment only exemplarily shows a part of the external pipeline 4.

[0075] The above-mentioned wire 5 includes an inner wire 50 and an outer wire 51 connected to each other, a portion of the inner wire 50 is located in the accommodating cavity 30, and another portion is located in the through hole 22, and the inner wire 50 is used to connect with the antenna 6. Exemplarily, a product line (not shown in the figure) of the antenna 6 partially extends into the through hole 22 to connect with the inner wire 50.

[0076] The external line 51 is partially located in the external pipe 4 and is used to connect to the device status monitoring system. That is, the internal line 50 extends in the accommodating cavity 30 and the through hole 22 and is connected to the antenna 6, and the external line 51 extends outside the base 3 and is connected to the device status monitoring system.

[0077] Exemplarily, the equipment status monitoring system is at a certain distance from the test tool 1, and the external pipe 4 extends from the base 3 to a range close to the equipment status monitoring system. Within the range close to the equipment status monitoring system, that is, away from the waterproof test environment, the external line 51 has no risk of contacting liquid, so the external pipe 4 is cut off, and the external line 51 extends out of the external pipe 4 and is connected to the equipment status monitoring system to monitor the current of the antenna 6.

[0078] By adopting the above technical solution, the extension direction of the mounting surface 20 ( Figure 2 The X direction is shown in the figure) and is inclined in the height direction ( Figure 2 The mounting surface 20 can be connected with the bottom surface 60 of the antenna 6, that is, the mounting surface 60 simulates the curved surface on the top surface of the car for mounting the antenna 6 (for example, above the rear windshield on the top of the car), so that the connection between the bottom surface 60 of the antenna 6 and the mounting surface 20 can more realistically simulate the installation state of the antenna 6 on the roof in the waterproof test, thereby obtaining a more realistic test result. That is, the problem that there is no suitable fixing method for the antenna 6 and the installation state of the antenna 6 on the roof cannot be simulated is solved.

[0079] The antenna 6 installed on the mounting surface 20 is connected to the internal wire 50, one end of the external wire 51 is connected to the internal wire 50, and the other end is connected to the device status monitoring system, that is, the antenna 6 is connected to the device status monitoring system, thereby achieving effective current monitoring during the waterproof test of the antenna 6, and then reflecting whether the circuit board inside the antenna 6 is flooded and whether its function is affected.

[0080] The base 3 is sealedly connected to the connecting portion 21, thereby preventing liquid from flowing into the accommodating cavity 30 and / or the through hole 22 from the connection between the base 3 and the connecting portion 21, causing the internal wire 50 to contact the liquid or the liquid to flow into the antenna 6, resulting in failure of the waterproof test. Similarly, the external pipe 4 covers the external wire 51 exposed outside the base 3 to protect the external wire 51 and prevent the external wire 51 from contacting the liquid and affecting the test.

[0081] In addition, the high temperature resistant fixture 2 facilitates the testing of the antenna 6 in a high temperature environment (eg, 90° C.) required by the standard. In a specific implementation, the IPX9K test of such shark fin antenna products using the test fixture 1 can reach a test speed of 6 pieces per day.

[0082] refer to Figure 5 In some possible implementations, the through hole 22 includes an extended hole 220 and a mounting hole 221 that are connected to each other. The mounting hole 221 is provided on the mounting surface 20. The upper opening area of ​​the mounting hole 221 is smaller than the cross-sectional area of ​​the extended hole 220. The mounting hole 221 is used to install the antenna.

[0083] For example, reference Figures 5 to 8 ,in, Figure 6 The left side cross-sectional view of the test fixture 1 with the antenna 6 installed. The antenna 6 includes a metal plate rib 62. The bottom surface 60 of the antenna 6 is provided with a plug-in column 61. The plug-in column 61 is provided with a first direction ( Figure 7 The plug-in column 61 extends through the mounting hole 221 to the extension hole 220 along the first direction, and then the metal sheet rib 62 is sleeved on the plug-in column 61 from bottom to top along the first direction, and the screw 63 is inserted into the slot 610 to fix the metal sheet rib 62 to the plug-in column 61.

[0084] The metal plate rib 62 is in an open U-shape, and includes a first rib piece 620 and a second rib piece 621. Figure 6 (as shown in the W direction), the first rib 620 and the second rib 621 are located on both sides of the plug-in post 61 and are symmetrically arranged about the plug-in post 61.

[0085] The mounting hole 221 is located above the first rib 620 and the second rib 621. The upper hole wall 222 of the extension hole 220 can abut against the first rib 620 and the second rib 621, thereby limiting the insertion column 61 from moving in the first direction ( Figure 5 The antenna 6 is moved upward (as shown in the Y direction) to prevent the antenna 6 from being loosened from the fixture 2.

[0086] In some possible implementations, the external pipe is threadedly connected to the outer wall of the base (not shown in the figure). That is, the reliability of the connection between the external pipe and the base is guaranteed. The present application does not limit the specific connection method between the external pipe and the base, and the external pipe and the base may also be connected in other ways, as long as the external pipe and the accommodating cavity can be connected.

[0087] In some possible implementations, reference Figure 4 The test fixture further includes a threaded joint (not shown in the figure), one end of the threaded joint is connected to the accommodating chamber 30, and the other end is connected to the external pipe 4, and the threaded joint is provided with an external thread; the outer wall 31 of the base 3 is provided with a side hole 32 connected to the accommodating chamber 30, and the side hole 32 is provided with an internal thread, and the external thread and the internal thread are connected. That is, the external pipe 4 and the accommodating chamber 30 are connected through the threaded joint, so that a part of the wire (i.e., the external wire 51) passes through the threaded joint to reach the external pipe 4, and extends outward to the connection device status monitoring system, thereby monitoring the current change from the antenna.

[0088] In some possible implementations, reference Figure 2 and Fig. 9The jig 2 is provided with two weight-reducing grooves, namely, a first groove 25 and a second groove 26. The first groove 25 is provided at the second end 201 of the jig 2, and the second groove 26 is provided at the first end 200 of the jig 2. The connecting portion 21 is located between the first groove 25 and the second groove 26. Exemplarily, the first groove 25 and the second groove 26 are formed by milling the inside of the jig 2 to reduce the weight of the jig 2, so that it is light to use and is convenient for waterproof testing of the antenna 6.

[0089] Exemplarily, the first groove 25 and the second groove 26 are both formed from the bottom surface of the fixture 2 in the height direction ( Fig. 9 The first groove 25 includes a layer of steps 251 (excluding the bottom wall of the groove), and the second groove 26 includes three layers of steps 261. It is easy to understand that the mass of material removed in the first groove 25 is greater than the mass of material removed in the second groove 26, thereby neutralizing the heavy end (second end 201) and light end (first end 200) of the fixture 2, thereby ensuring the balanced mass distribution of the fixture 2 as much as possible to prevent it from tipping over.

[0090] In some possible implementations, reference Fig. 9 and Fig.10 , the base 3 and the connecting portion 21 are screwed together. That is, the reliability of the connection between the base 3 and the fixture 2 is ensured to prevent the base 3 and the fixture 2 from loosening or falling off under high pressure spraying.

[0091] refer to Figure 5 , Fig. 9 and Fig.10 , along the height direction ( Fig. 9 (shown in the Z direction), a first sealing ring 7 is provided between the base 3 and the connecting portion 21; the connecting portion 21 is provided with a first annular groove 210 surrounding the lower opening 223 of the extension hole 220, and part of the first sealing ring 7 is embedded in the first annular groove 210 along the height direction. That is, the first sealing ring 7 is located between the base 3 and the connecting portion 21 of the fixture 2, and the base 3 and the connecting portion 21 are fitted together along the height direction and screwed together, thereby forming an extrusion on the first sealing ring 7, thereby achieving a seal between the base 3 and the connecting portion 21, and effectively preventing liquid from entering the accommodating cavity 30 and / or the through hole 22 from between the base 3 and the connecting portion 21, causing wire or antenna failure. Exemplarily, the first annular groove 210 is rectangular, which surrounds the lower opening 223 of the extension hole 220, which is also rectangular, and the two form a U-shape.

[0092] Exemplarily, the material of the first sealing ring 7 is EPDM rubber, which has a temperature resistance of -60°C to +150°C, thus being more conducive to testing the antenna in a high temperature environment (eg, 90°C) required by the standard.

[0093] In some possible embodiments, a first circular area 224 is formed between the first annular groove 210 and the lower opening 223 of the extension hole 220, and the first circular area 224 is provided with a plurality of first screw holes 225, and the plurality of first screw holes 225 are symmetrically distributed about the center of the lower opening 223; a surface 33 of the base 3 for connecting the connecting part 21 is provided with an opening 330, and the opening 330 connects the extension hole 220 and the accommodating cavity 30, and a plurality of second screw holes 332 corresponding to the plurality of first screw holes 225 are provided around the upper opening 331 of the opening 330; the plurality of first screw holes 225 and the plurality of second screw holes 332 are provided for screwing the base 3 and the connecting part 21.

[0094] Exemplarily, the opening 330 is located at the center of the surface 33 of the base 3. The upper opening 331 of the opening 330 is smaller than the cross-sectional area of ​​the accommodating cavity 30, and the opening 330 allows the internal wire to extend downward from the extension hole 220 to enter the accommodating cavity 30.

[0095] Optionally, the first screw hole 225 and the second screw hole 332 each include four, and the four first screw holes 225 are located at the four corners of the rectangular lower opening 223, and are spaced apart from the four corners of the lower opening 223. The four second screw holes 332 are located at the four corners of the rectangular upper opening 331, and are spaced apart from the four corners of the upper opening 331.

[0096] That is, the base 3 and the connecting portion 21 include four connecting points, and the four connecting points are centrally symmetrically distributed, thereby ensuring the stability of the connection between the base 3 and the connecting portion 21 on the one hand, and making the mass distribution balanced on the other hand, thereby preventing the fixture 2 and the base 3 from tipping over.

[0097] Optionally, this embodiment uses M5 standard screws to fix the base 3 and the connecting portion 21 .

[0098] In some possible implementations, reference Fig.10 and Fig.11 The base 3 includes a main body 34 and a bottom plate 35.
