Description
Technical Field
[0001] The present application relates to the technical field of drone control equipment production, and in particular to a tooling that can be used for module testing of drone control equipment. Background Art
[0002] Drone control equipment controls or drives away drones by receiving, interfering, deceiving, and attacking drone signals. These functions are achieved by the cooperation of modules and antennas inside the equipment. During the production process of drone control equipment, the modules need to undergo indoor and outdoor tests first, and then be assembled after confirming that their various parameters are qualified. During outdoor testing, the antenna needs to be connected and kept roughly vertically facing upwards.
[0003] At present, during the test process, the modules to be tested, cables and other components are directly placed on the test bench in a scattered manner. The position of the modules to be tested is easy to change and the cables are easy to be entangled, which can easily lead to disconnection of electrical connections or damage to the modules. In addition, the random placement of the modules leads to low space utilization of the test bench. In the test process, the modules generate severe heat, which makes them easy to be damaged. When switching between indoor and outdoor tests, each component needs to be moved separately and the cables need to be re-arranged to make electrical connections of each component, which leads to low test efficiency. When conducting outdoor tests, a single worker holds the antenna, which leads to high tester costs. In addition, the test often needs to be interrupted to give the worker holding the antenna a break, which leads to low test efficiency.

[0029] The present application provides a module testing tool that can be used in module testing of drone control equipment or module testing of other equipment.
[0030] In order to enable those skilled in the art to better understand the technical solution of the present application, Figure 1-5 The present application is further described in detail with specific implementation methods.
[0031] like Figure 1 and Figure 2 As shown, the module test fixture includes a base plate 1, a cooling fan 2, an electrical access portion 3 and a fixing unit 4. The cooling fan 2, the electrical access portion 3 and the fixing unit 4 are all connected to the base plate 1, and the connection method can be any connection method that can achieve relative fixation to the base plate 1, such as threaded connection, welding, and clamping.
[0032] The substrate 1 has a front side and a back side along the thickness direction of the substrate 1. The cooling fan 2 is connected to the back side of the substrate 1, and the fixing unit 4 is connected to the front side of the substrate 1. The fixing unit 4 includes a module fixing part 41, and the module fixing part 41 is used to fix the module to be tested.
[0033] When testing the module, the above-mentioned module testing tooling is used to fix the position of the module under test relative to the substrate 1, so that it is not easy to cause the electrical connection to be disconnected or the module to be damaged due to the change of the position of the module under test. Moreover, the module under test can only be placed at a specific position of the substrate 1, so that the space utilization rate will not be low due to random placement. In addition, the cooling fan 2 can dissipate the heat of the module under test during the test process, thereby avoiding the problem of damage to the module under test due to overheating. Moreover, when switching between indoor testing and outdoor testing, it can be transported as a whole without the need to re-establish the electrical connection between the modules under test and between the modules under test and the electrical access part 3, so that it can switch quickly and achieve higher test efficiency.
[0034] like Figure 2 As shown, in this embodiment, the heat dissipation fan 2 includes a housing 21, blades 22 and a protective net 23. The blades 22 are installed in the housing 21, and the protective net 23 is sealed on the side of the housing 21 away from the substrate 1. The protective net 23 prevents the blades 22 from rotating and accidentally injuring the staff. The wind generated by the rotation of the blades 22 is discharged through the mesh gaps of the protective net 23 to dissipate heat for the module under test. In actual implementation, the structure of the heat dissipation fan 2 can be designed according to actual needs.
[0035] like Figure 1 As shown, in this embodiment, the electrical access part 3 is connected to the front side of the substrate 1. The electrical access part 3 includes an air plug 32 and a power adapter 31. During testing, the air plug 32 is connected to an external power source (such as an AC power source) to introduce electricity into the power adapter 31. The power adapter 31 converts the voltage into a voltage suitable for the operation of the module under test and supplies power to the unit under test through a cable. In actual implementation, the electrical access part 3 can also be connected to the back side of the substrate 1. The structure of the electrical access part 3 can be designed according to actual needs. In addition, a battery can also be configured to provide power for testing.
[0036] like Figure 3As shown, in this embodiment, the module fixing part 41 includes a clamping assembly 411 and a positioning part 412. Among them, the clamping assembly 411 includes a threaded hole column 4111, a pressure plate 4112, and a hand screw 4113. The threaded hole column 4111 is connected to the front side of the substrate 1. The pressure plate 4112 is provided with a connection hole. The nail body of the hand screw 4113 passes through the connection hole on the pressure plate 4112 and is screwed to the threaded hole column 4111, so that the pressure plate 4112 applies a pressure toward the substrate 1 to the module under test, so that the module under test can be pressed along the thickness direction of the substrate 1. The tightening and loosening of this clamping assembly 411 does not require tools, is easy to operate, and is conducive to improving the test efficiency. Moreover, the threaded holes of the module under test itself will not be used, avoiding damage to the threaded holes of the module under test itself, resulting in the problem of subsequent inability to assemble. Among them, the positioning part 412 is used to limit the position of the module under test in the width direction and length direction of the substrate 1. In this embodiment, three module fixing parts 41 are provided. The positioning parts 412 of the first module fixing part 41a and the second module fixing part 41b are positioning grooves 412a that are shaped like the first module 011 and the second module 012, respectively. The positioning grooves 412a are formed by partially recessing from the front side to the back side of the substrate 1. The positioning part 412 of the third module fixing part 41c is a positioning pin 412b connected to its pressing plate 4112. The positioning pin 412b is connected to the positioning hole 013a of the third module 013 itself (see Figure 4 In actual implementation, the structure of the module fixing portion 41 can be designed according to actual needs. For example, the positioning portion 412 may not be provided, and the pressing component 411 may be replaced by a buckle component.
[0037] A heat-conducting layer may be provided in the area corresponding to the module under test on the front side of the substrate 1, so that the heat of the module under test can be quickly dissipated to the substrate 1 through the heat-conducting layer, thus further improving the heat dissipation effect of the module under test. The heat-conducting layer may be a heat-conducting silicon pad or a heat-conducting silicone grease, etc. The heat-conducting silicon pad may be provided on the substrate 1 in the form of adhesive, and the heat-conducting silicone grease may be provided on the substrate 1 in the form of coating.
[0038] like Figure 2 As shown, an air flow groove 11 can be provided on the back side of the substrate 1, and the back side of the substrate 1 is partially recessed toward the front side to form the air flow groove 11, so that the heat dissipation area can be increased, thereby further improving the heat dissipation effect of the module under test. The area of the air flow groove 11 can be designed according to actual needs. Under the premise of ensuring the strength of the substrate 1, the area of the air flow groove 11 can be as large as possible.
[0039] like Figure 2As shown, the module test fixture may also include a substrate bracket 6, which is connected to the back side of the substrate 1, and the connection method may be any connection method that can achieve fixation relative to the substrate 1, such as threaded connection, welding, and clamping. The protruding height of the substrate bracket 6 relative to the back side of the substrate 1 is higher than the protruding height of the cooling fan 2 relative to the back side of the substrate 1. In this way, when performing indoor testing, the substrate 1 is laid flat on the test bench with the front side facing up, and a flow gap can be formed between the substrate 1, the fan and the test bench. The flow gap is conducive to the fan generating wind and the discharge of hot air after heat exchange with the module, thereby further improving the heat dissipation effect of the module under test.
[0040] like Figure 1 As shown, the fixing unit 4 may also include an antenna fixing portion 42 for fixing the antenna 02 electrically connected to the module under test. In this way, when performing outdoor testing, the staff does not need to hold the antenna, thereby reducing the cost of the test personnel and saving the rest time of the staff holding the antenna, thereby further improving the test efficiency. In this embodiment, the antenna fixing portion 42 is a socket structure, and the antenna is fixed by inserting the jack of the socket. In actual implementation, the structure of the antenna fixing portion 42 can be designed according to actual needs. For example, the antenna fixing portion 42 can also be a clamp structure, which is clamped around the periphery of the antenna to fix the antenna.
[0041] Along the width direction of the substrate 1, the substrate 1 has an upper side and a lower side. A preferred layout is that the electrical access portion 3 is connected to the front side of the substrate 1 and is closer to the lower side of the substrate 1 than the fixing unit 4. For the same fixing unit 4, its antenna fixing portion 42 is closer to the upper side of the substrate 1 than its module fixing portion 41. Its multiple module fixing portions 41 used simultaneously are arranged in sequence along the width direction of the substrate 1, and its multiple module fixing portions 41 used selectively are arranged in sequence along the length direction of the substrate 1. For example, Figure 1 In the test, the first module and the second module or the first module and the third module will be tested at the same time, so the first module fixing part 41a and the second module fixing part 41b or the first module fixing part 41a and the third module fixing part 41c will be used at the same time, and the second module fixing part 41b and the third module fixing part 41c will be used selectively, the first module fixing part 41a and the second module fixing part 41b are arranged in sequence along the width direction of the substrate 1, the first module fixing part 41a and the third module fixing part 41c are arranged in sequence along the width direction of the substrate 1, and the second module fixing part 41b and the third module fixing part 41c are arranged in sequence along the length direction of the substrate 1. This layout makes the overall structure compact, meets the space requirements for disassembly and assembly operations, reduces the probability of bumping and damaging the tested module during the disassembly and assembly process, and also meets the cable wiring requirements, making the cable length shorter and the cable bending radius larger.
[0042] like Figure 1As shown, the substrate 1 may be provided with a wire hole 12. The wire hole 12 passes through the front side and the back side of the substrate 1, and the cable can pass through the wire hole 12 from the front side to the back side of the substrate 1. In this way, the cable occupies less space on the front side of the substrate 1, so that more fixing units 4 can be arranged on the front side of the substrate 1. In this embodiment, a wire hole 12 is provided on the outlet side of the power adapter 31 and the inlet side of the three first module fixing parts 41a. In actual implementation, the number and position of the wire holes 12 can be adjusted according to actual needs.
[0043] like Figure 1 As shown, the base plate 1 may be provided with a cable fixing hole 13. The cable fixing hole 13 runs through the front side and the back side of the base plate 1, and the cables can be bundled and fixed through the cable fixing hole 13, so that the wiring can be ensured to be neat and the problem of disconnection of electrical connection caused by the cables being tangled in disorder can be avoided. The number and position of the cable fixing holes 13 can be designed according to actual needs.
[0044] like Figure 1 As shown, the number of fixing units 4 is preferably multiple, so that multiple sets of module tests can be carried out simultaneously to achieve higher test efficiency. In this embodiment, three fixing units 4 are provided, and in actual implementation, one, two or more than three fixing units 4 may also be provided. When multiple fixing units 4 are provided, each fixing unit 4 is arranged in sequence along the length direction of the substrate 1, so that it is more conducive to meeting the requirements of the disassembly and assembly space and the cable wiring requirements, and the space utilization rate is higher.
[0045] like Figure 2 As shown, the module test fixture may further include a hanger 55, which may be connected to the front side or the back side of the substrate 1, and the connection method may be threaded connection, welding, clamping, or any other connection method that can achieve fixation relative to the substrate 1. The number of the hangers 55 may be one or more, and in this embodiment, two hangers 55 are provided. Figure 5 , Figure 6 As shown, when conducting outdoor testing, the substrate 1 can be vertically hung on the external bracket 03 by the hanger 55 with the upper side (along the width direction of the substrate 1, the substrate 1 has an upper side and a lower side) on top, so that the substrate 1 and the components connected to the substrate 1 can be placed at a height position that is convenient for staff to operate and observe.
[0046] In summary, using the module testing tooling provided in this application when testing modules can reduce the chances of overheating damage and collision damage to the tested modules, improve module testing efficiency, reduce the chances of electrical connection disconnection during the testing process, and reduce testing costs.
[0047] The above specific examples are used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
