Technical Field

[0001] The utility model relates to the technical field of electronic testing, in particular to an electronic testing device. Background Art

[0002] Electronic testing is a testing activity performed on electronic components, circuit boards, equipment or systems during the development and production of automotive electronic equipment or automotive electronic system products to ensure that they meet design specifications and performance requirements. The purpose of electronic testing is to identify possible defects in electronic components, circuit boards, equipment or systems to ensure the reliability, stability and performance of automotive electronic parts.

[0003] Regarding electronic testing devices, after searching, it was found that the comparative document (authorization announcement number CN215437799U) is a portable automotive electronic test box. The setting of damping pads can prevent the test box body from directly hitting the top of the box when it moves upward due to vibration or rebound of the mounting plate. The damping pad can prevent the test box body from being damaged, solving the problem of poor shock absorption effect of previous portable automotive electronic test boxes. However, the portable automotive electronic test box still has certain defects and shortcomings in actual use: when testing the electronic components of the car, the box and the test box body are placed on the ground for operation, and the box body has no frame support. When the test box body is in use, there is a height difference between it and the electronic components tested in the car, and the tester needs to bend over to operate, which is very inconvenient. At the same time, after the box cover is opened, the box cover part has no support and protection, so that the box cover sinks under its own gravity and hits the outside of the box. Moreover, the box cover is placed under force and sinks for a long time, which easily causes the hinge between the box cover and the box body to be damaged, resulting in the box cover and the box cover being loose, which in turn causes dust to fall on the test box body, resulting in poor contact at the test line connection after encountering dust, affecting the use of electronic testing.

[0027] Among them, reference Figure 2-Figure 4 A plurality of connection sockets 203 are provided on one side of the top of the test device 201, a voltmeter 204 is provided on one side of the connection socket 203, an ammeter 205 is provided on one side of the voltmeter 204, a test line 206 is provided on the top of the connection socket 203, a connection plug for use with the connection socket 203 is provided at one end of the test line 206, and a test plug is provided at the other end.

[0028] When the test equipment 201 is in use, the test equipment 201 is placed inside the box 2, and a support seat of an L-shaped structure is provided on both sides of the box 2. Then the four corner limiters at the bottom of the test equipment 201 are placed so that the test equipment 201 is fixed and clamped inside the box 2. After the test equipment 201 is placed firmly, the through-hole 5 of the box 2 is placed on the mounting plate 403 at the top of the electric push rod 402. Screw holes are provided on both sides of the top of the mounting plate 403 and both sides of the bottom of the box 2. After the box 2 contacts the mounting plate 403, bolts are screwed from the screw holes of the mounting plate 403 into the screw holes of the box 2, and the box 2 is fixedly mounted on the mounting plate 403 and placed, and the box 2 is supported by the electric push rod 402.

[0029] When testing automotive electronic components, the connecting plug at one end of the test line 206 is inserted into the connecting jack 203, and the test plug at the other end is inserted into the interface of the electronic component. After the test equipment 201 and the electronic component are connected through the test line 206, the voltage and current of the electronic component can be tested by the voltmeter 204 and the ammeter 205 to see if they are normal. When the pointers on the voltmeter 204 and the ammeter 205 can turn upward, it means that the electronic component can be used normally. When the pointers on the voltmeter 204 and the ammeter 205 cannot turn, it means that the circuit connection of the electronic component has poor contact and needs to be repaired.

[0030] Among them, reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The lifting assembly includes: a fixed platform 4 fixedly installed between the test frame 1 and the mobile base 3, limited holes 401 are opened on both sides of the top of the fixed platform 4, an electric push rod 402 fixedly installed inside the limited hole 401, a mounting plate 403 fixedly installed on the top of the electric push rod 402, and a through opening 5 opened inside the test frame 1 for accommodating the box 2.

[0031] During the test of automotive electronic components by the test equipment 201, since the electric push rod 402 supports and places the box 2 and the test equipment 201, the box 2 is located inside the through opening 5, and the length and width of the through opening 5 are larger than the length and width of the box 2. When it is necessary to adjust the height of the test equipment 201 to be consistent with the height of the automotive electronic components, the electric push rod 402 is started to push the mounting plate 403 and the box 2 to move upward, so that the box 2 is moved out from the inside of the through opening 5, and the test equipment 201 is driven to move upward, so that the height position of the test equipment 201 is adjusted to avoid the height position difference between the test equipment 201 and the automotive electronic components, which is convenient for the testing of automotive electronic components. There is no need for the tester to bend down to operate, and the test equipment 201 is convenient to use. When the box 2 moves up and down inside the through opening 5, there is a gap between the box 2 and the through opening 5 to avoid friction damage between the box 2 and the through opening 5.

[0032] Among them, reference Figure 1-Figure 2 A storage box 8 for placing the test line 206 is installed at the outer end of the test frame 1, and sponge blocks 801 are fixed to both sides of the inner wall and the inner bottom of the storage box 8 by glue.

[0033] After testing the automotive electronic components, unplug the connecting plug at one end of the test line 206 from the connecting jack 203, and unplug the test plug at the other end from the interface of the electronic component. Remove the test line 206 from the test equipment 201 and put it into the storage box 8 to avoid the loss of the test line 206 and facilitate taking it when in use. When the test line 206 is placed in the storage box 8, the sponge block 801 can be used to protect the connecting plug and the test plug of the test line 206 from collision, so as to prevent the connecting plug and the test plug from being damaged by collision with the inside of the storage box 8.

[0034] Among them, reference Figure 3 A magnetic sheet ring 7 is embedded in the top of the box body 2 , and an iron sheet ring 701 magnetically connected to the magnetic sheet ring 7 is embedded in the inner side of the box cover 202 .

[0035] After removing the test line 206 from the test equipment 201, flip the box cover 202 over and cover the top of the box body 2. At this time, the iron sheet ring 701 on the inside of the box cover 202 is just aligned with the magnetic sheet ring 7 on the top of the box cover 202, so that the iron sheet ring 701 is magnetically fixed to the magnetic sheet ring 7, and then the box cover 202 is fixed to the top of the box body 2, so as to seal the test equipment 201 and prevent dust.

[0036] Among them, reference Figure 1-Figure 2 A control panel 9 is fixedly installed on the outside of the fixed platform 4, the control panel 9 and the electric push rod 402 are connected by wires, a power cord 901 is installed on the outside of the control panel 9 and the bottom of the test equipment 201, and a power plug 902 is installed at one end of the power cord 901.

[0037] When the electric push rod 402 and the test equipment 201 are in use, the control panel 9 and the electric push rod 402 are connected by electric wires, and power cords 901 are installed on the outside of the control panel 9 and the bottom of the test equipment 201. The power plug 902 is inserted into the indoor socket to turn on the power, so that the control panel 9, the electric push rod 402 and the test equipment 201 can be powered on and used. The control panel 9 is provided with a switch button, an up button and a down button, which can control the start and stop of the electric push rod 402, as well as the up and down of the electric push rod 402. The control program involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the utility model.

[0038] Example 2
