Description

Technical Field

[0001] The utility model relates to the field of electromagnetic immunity testing, in particular to an anti-interference performance detection device. Background Technique

[0002] The vehicle anti-interference test is used to test whether the whole vehicle meets the electromagnetic compatibility requirements, which means that the equipment or system operates in compliance with the requirements in its electromagnetic environment and does not produce adverse electromagnetic interference to any other equipment in its environment, and can ensure the stability and reliability of the vehicle electronic system and equipment. Therefore, an anti-interference performance detection device is needed.

[0003] In the prior art, the lighting in the anti-interference device is usually provided by a halogen lamp, but the halogen lamp generates a large amount of heat and has a short service life, so it needs to be frequently replaced. When replacing the halogen lamp, it is usually necessary to approach the halogen lamp by a ladder for replacement, which is rather troublesome. At the same time, the test antenna in the prior art usually adopts a fixed installation method at a certain place, which will cause incomplete coverage of electromagnetic signals when testing a larger vehicle, affecting the detection effect.

[0004] Therefore, the utility model provides an anti-interference performance detection device to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and an anti-interference performance detection device is proposed. The device can quickly disassemble and install the halogen lamp through a fixing mechanism, and use a winch to adjust the height of the halogen lamp for easy replacement and maintenance, and can use an adjusting mechanism to synchronously move two connecting blocks, so as to adjust the coverage angle of the test antenna.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] An anti-interference performance detection device includes a wall and a sliding seat. Push-pull doors are slidably penetrated through both ends of the front and back of the wall near one side. A winch is fixedly arranged at the center of the upper end surface of the outer wall of the wall. A first motor is fixedly arranged at the upper end of the front end surface of the winch. A cable is movably sleeved on the outer wall of the inner shaft of the winch. A first threaded rod is rotatably arranged at the upper end of the center of one side of the inner wall of the wall. Slide rods are fixedly arranged at both ends near the front and back of the upper end of one side of the wall. A fixed seat is fixedly arranged at the upper end of the outer wall of the wall. A second motor is fixedly arranged on the upper end surface of the fixed seat. A base is fixedly arranged at one side of the bottom end surface of the inner wall of the wall. An adjusting mechanism is arranged inside the base, and the adjusting mechanism includes a worm.

[0008] Vertical rods are fixedly arranged at both the front and rear ends of the upper end face of the base. At the center of the upper end faces of the inner walls of the two vertical rods, second threaded rods are rotatably arranged. Slide blocks are slidably arranged on the inner walls of the two vertical rods. Moving grooves are formed at the centers of the front and rear end faces of the inner wall of the slide block. Fixing mechanisms are arranged in the two moving grooves. The two fixing mechanisms each include a clamping plate. A mounting seat is embedded in the inner wall of the slide block. At the center of the bottom end face of the mounting seat, a halogen lamp is fixedly arranged. Clamping grooves are formed at the centers of the front and rear end faces of the mounting seat.

[0009] Through the above technical solution, the rotation of the inner shaft of the winch can be controlled by the motor to release and wind up the cable, facilitating the adjustment of the height of the halogen lamp through the cable. The position of the halogen lamp can be fixed by the fixing mechanism, and the irradiation range of the light can be adjusted by the threaded rod and the slide rod, achieving the effect of full - field illumination with one lamp, preventing electromagnetic interference when multiple lamps are used together. At the same time, the adjusting mechanism can be used to synchronously rotate the two second threaded rods, thereby driving the two slide blocks to move vertically synchronously.

[0010] Further, the worm is rotatably arranged on one side of the rear end face of the inner wall of the base. At the front and rear ends of the lower end face of the inner wall of the base, worm wheels are rotatably arranged. The two worm wheels are respectively fixedly sleeved on the outer walls of the lower ends of the two second threaded rods. A knob is fixedly arranged on the front end face of the worm. The two worm wheels are meshed with the worm.

[0011] Through the above technical solution, the rotation of the knob can drive the two worm wheels to rotate through the worm, so that the two second threaded rods can rotate synchronously.

[0012] Further, the two clamping plates are respectively slidably arranged in the two moving grooves. At the centers of the opposite sides of the two clamping plates, connecting rods are fixedly arranged. Spring sleeves are movably sleeved on the outer walls of the two connecting rods. The two ends of the two springs are respectively fixedly connected to the two clamping plates and the two moving grooves. Pull rings are fixedly arranged on the opposite sides of the two connecting rods. The two clamping plates are respectively embedded in the two clamping grooves.

[0013] Through the above technical solution, the position of the halogen lamp can be fixed by driving the clamping plate to be embedded in the clamping groove.

[0014] Further, the two slide blocks are respectively threadedly sleeved on the outer walls of the two second threaded rods. A control box is fixedly arranged on the opposite side of the two slide blocks. A test antenna is fixedly arranged at the center of one side of the control box.

[0015] Through the above technical solution, the rotation of the two threaded rods can drive the two slide blocks to drive the control box and the test antenna to adjust the height, making the coverage of the test antenna wider.

[0016] Further, a threaded groove is penetrated and provided at the center of one side of the sliding seat, and sliding grooves are penetrated and provided at both ends near the front and rear of the center of one side of the sliding seat. The first threaded rod is threadedly sleeved on the inner wall of the threaded groove, and the two sliding rods are respectively slidably sleeved in the two sliding grooves;

[0017] Through the above technical solution, the sliding seat can be driven to move along the sliding rod by rotating the first threaded rod, which is convenient for adjusting the irradiation range of the halogen lamp.

[0018] Further, a first through hole is penetrated and provided at a position near one side of the center of the upper end surface of the outer wall of the wall. A second through hole is penetrated and provided at a position near the rear end of the center of the upper end surface of the inner wall of the sliding seat. The cable penetrates through the first through hole and the second through hole and is fixedly arranged with the mounting seat;

[0019] Through the above technical solution, the height of the mounting seat can be adjusted by winding and unwinding the cable, avoiding the relatively cumbersome replacement method of approaching the halogen lamp by ladder.

[0020] Further, a ramp is fixedly provided at the lower end of one side of the wall. Sliding doors are slidably arranged at both ends of the front and rear of one side of the bottom end surface of the inner wall of the wall. The two sliding doors respectively penetrate through the front and rear end surfaces of the outer wall of the wall near one side. Electromagnetic shielding plates are fixedly provided on one side of the inner wall of the wall and the two sliding doors;

[0021] Through the above technical solution, the sliding doors and the ramp facilitate the entry and exit of vehicles, and the electromagnetic shielding plates can prevent electromagnetic radiation from affecting the external environment.

[0022] Further, the inner shaft of the winch is fixedly connected to the output end of the first motor, and the first threaded rod is fixedly connected to the output end of the second motor;

[0023] Through the above technical solution, the inner shaft of the winch and the first threaded rod can be respectively driven to rotate by the first motor and the second motor, achieving the effect of labor saving.

[0024] The utility model has the following beneficial effects:

[0025] 1. For an anti-interference performance detection device proposed by the utility model, by pulling two pull rings to both sides with a long-handled tool, the pull rings move and drive two clamping plates to slide into the moving groove through two connecting rods, so that the two clamping plates are disengaged from the clamping grooves. Then, the motor is started to drive the inner shaft of the winch to rotate, so that the cable on the outer wall of the inner shaft of the winch is relaxed, so that the mounting seat can drive the halogen lamp to move downward, reducing the safety hazard in the process of the staff approaching the halogen lamp by ladder, and making the maintenance and replacement work of the halogen lamp more convenient.

[0026] 2. An anti-interference performance detection device proposed by the present utility model rotates the knob to drive the worm to rotate towards one side. Through the worm, two meshing worm wheels rotate synchronously, thereby driving the second threaded rod fixedly sleeved on the inner walls of the two worm wheels to rotate, so that the connecting blocks threadedly sleeved on the outer walls of the two second threaded rods drive the control box and the test antenna to move vertically, and the coverage angle of the test antenna can be adjusted to prevent the detection accuracy from being affected due to incomplete coverage of the test antenna when testing large vehicles.

[0038]

[0039] When testing a vehicle, open the two sliding doors 2 to both sides, and then drive the vehicle into the device through the ramp 3 for testing. When the halogen lamp 17 has reached its service life after long-term operation and needs to be replaced, two long-handled tools can be used to pull the two pull rings 2804, so that the connecting rod 2802 fixed on the opposite sides of the two pull rings 2804 can drive the two clamping plates 2801 to slide into the two moving grooves 23 respectively, so that the two clamping plates 2801 are disengaged from the two clamping grooves 24 respectively. Then start the first motor 6 to drive the inner shaft of the winch 5 to rotate, and loosen the cable 7 on the outer wall of the inner shaft of the winch 5, so that the cable 7 can move downward along the first through hole 8 and the second through hole 22, so that the mounting seat 25 and the halogen lamp 17 can move downward. After the mounting seat 25 is lowered to the ground position, the halogen lamp 17 can be replaced. After the replacement is completed, reverse the first motor 6 to wind up the cable 7 to make the mounting seat 25 embed into the inner wall of the sliding seat 16, and then release the two pull rings 2804 to make the clamping plate 2801 embed into the clamping groove 24 under the action of the spring 2803 to fix the position of the mounting seat 25, making the replacement process of the halogen lamp 17 more convenient;

[0039] When testing a large vehicle, first start the second motor 13 to drive the first threaded rod 15 to rotate in the threaded groove 27, thereby pushing the sliding seat 16 to slide on the outer wall of the slide rod 14 through the chute 26, so that the halogen lamp 17 can illuminate the test antenna 11. Then rotate the knob 2101 to one side to drive the worm 2103 to rotate, and drive the two meshing worm wheels 2102 to rotate synchronously through the worm 2103, so that the two worm wheels 2102 respectively drive the two second threaded rods 20 to rotate, facilitating the adjustment of the vertical height of the connection blocks 19 threadedly sleeved on the outer walls of the two second threaded rods 20, so that the two connection blocks 19 drive the test antenna 11 and the control box 18 to move vertically to adjust the coverage angle of the test antenna 11, preventing the test antenna 11 from failing to cover the large vehicle and affecting the test accuracy, and the electromagnetic shielding plate 4 can prevent the test antenna 11 from affecting the external environment.

[0040] Working principle: The fixing mechanism 28 cooperates with the cable 7 and the winch 5 to fix and remove the mounting seat 25, facilitating the replacement of the halogen lamp 17, avoiding the need to approach the halogen lamp 17 by ladder when replacing the halogen lamp 17, reducing the danger during the replacement process and making the replacement procedure more convenient. Moreover, the adjusting mechanism 21 can drive the two second threaded rods 20 to rotate synchronously, thereby adjusting the height of the two connection blocks 19, and driving the control box 18 and the test antenna 11 to move through the two connection blocks 19, preventing the test antenna 11 from failing to cover the whole vehicle when testing a large vehicle and preventing the influence on the test accuracy.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
