[0023] In the specific implementation process, Figures 1 to 5As shown, the performance testing device of the vehicle-mounted wireless product provided by the utility model includes a testing platform 1, on one side of the top of which is detachably connected to a host fixture frame 2 by bolts, the host fixture frame 2 is inclined from the upper edge position of the testing platform 1 to the center thereof, and a control cylinder 3 is fixedly connected to the host fixture frame 2, which is used to push the wiring probe to connect with the tested host, and a fixture frame 4 is fixedly connected to the host fixture frame 2 on the outside of the control cylinder 3, and clamping components are symmetrically distributed at both ends of the clamp frame 4 along the vertical center line of the host clamp frame 2, and the clamping components are used to limit the two sides of the tested host, and two smoothing components for smoothing the clamping components are also arranged on the top of the clamp frame 4.
[0024] Before testing, the spacing between the clamping components on the clamp frames 4 on both sides is first extended to a larger width, and then the host to be tested is placed between the host clamp frame 2 and the clamp frame 4 until it reaches the clamping component brackets on both sides, and the two clamping components are used to clamp and fix the two sides of the host to be tested, and then the control cylinder 3 is used to push the wiring probe to connect with the host to be tested, so that its performance can be checked through the set display. After the test is completed, the wiring probe of the control cylinder 3 is separated from the host to be tested, and the clamping components on both sides are reset so that the host to be tested can be taken out;
[0025] During the movement, the clamping components will move toward each other and gradually contact the smoothing component. After contacting the smoothing component, it will drive it to move toward the top. It will generate a certain resistance during the movement, so that the clamping components can be in a flat state when contacting the component under test, so that it can be docked with the host under test in different forms, improving its applicability;
[0026] The clamping assembly includes a telescopic cylinder 5, which is fixedly connected to the top of the main machine clamp frame 2. The output end of the telescopic cylinder 5 passes through the clamp frame 4 and is fixedly connected to an arc-shaped outer frame 6. An arc-shaped inner frame 1 7 is respectively provided at both ends of one side of the arc-shaped outer frame 6. An arc-shaped inner frame 2 8 is respectively provided at both ends of the side away from the arc-shaped outer frame 6. A semicircular block 9 is respectively provided at both ends of the side away from the arc-shaped inner frame 1 7. An arc-shaped guide groove 1 is respectively provided at both ends of one side of the arc-shaped outer frame 6. The arc-shaped inner frame 1 7 can slide in the arc-shaped guide groove 1. An arc-shaped guide groove 2 is respectively provided at both ends of one side of the arc-shaped inner frame 1 7. The arc-shaped inner frame 2 8 can slide in the arc-shaped guide groove 2. An arc-shaped guide groove 3 is provided on the arc-shaped inner frame 2 8. The semicircular block 9 can slide in the arc-shaped guide groove 3. The outer wall of the semicircular block 9 fits with the smoothing assembly.
[0027] The smoothing component includes a trapezoidal oblique frame 10, the outer oblique bottom surface of the trapezoidal oblique frame 10 is fitted with the semicircular block 9, and a sliding rod 11 is fixedly connected to the top thereof. The top of the sliding rod 11 extends through the top of the clamp frame 4 and the radial dimension becomes larger. A spring 12 is sleeved on the outer side of the sliding rod 11, and the two ends of the spring 12 are respectively fixedly connected to the inner top wall of the clamp frame 4 and the top of the trapezoidal oblique frame 10. Arc-shaped grooves are respectively opened at the two ends of the bottom of the trapezoidal oblique frame 10, and a movable roller 13 is rotatably connected in the arc-shaped groove of the trapezoidal oblique frame 10.
[0028] The working principle provided by the utility model is as follows: when the utility model is implemented, before testing, the spacing between the clamping components on the clamp skeletons 4 on both sides is first extended to a larger width, and then the required host to be tested is placed between the host clamp frame 2 and the clamp skeleton 4, until it reaches the clamping component brackets on both sides, and the two sides of the host to be tested are clamped and fixed by the two clamping components, and then the control cylinder 3 pushes the wiring probe to connect with the host to be tested, so that its performance can be checked through the set display, and after the test is completed, the wiring probe of the control cylinder 3 is separated from the host to be tested, and the clamping components on both sides are reset so that the host to be tested can be taken out;
[0029] During the clamping process, the multiple semicircular blocks 9 on both sides will first contact the host under test, and the driving force of the telescopic cylinder 5 will make the semicircular blocks 9 reach the threshold of the rotation angle on the host under test, so that the subsequent arc-shaped inner frame 2 8 and arc-shaped inner frame 1 7 successively reach the threshold of the rotation angle, and the host under test is fixed. After separation from the host under test, the clamping assembly is transformed into an irregular shape through the shape of the host under test, and then reset by the telescopic cylinder 5;
[0030] When the clamping assembly is moving to fix the host under test again, it will move to the side close to each other and gradually contact the smoothing assembly. After contacting the smoothing assembly, it will drive it to move to the top. It will generate a certain resistance during the movement, so that the clamping assembly can be in a flat state when contacting the host under test, so that it can be docked according to different forms of the host under test, improving its applicability;
[0031] The irregular shape of the clamping assembly contacts the trapezoidal inclined frame 10 during the movement, and due to its plane setting, after the trapezoidal inclined frame 10 is squeezed, the semicircular block 9, the arc-shaped inner frame 2 8 and the arc-shaped inner frame 1 7 are successively restored to a horizontal state, and the trapezoidal inclined frame 10 slides to the top according to its squeezing force and realizes pressure contraction on the spring 12 until it reaches the upper end of the clamping assembly. At this time, the movable roller 13 contacts it and reduces friction. The above operation is repeated during subsequent resetting to make the clamping assembly pass.
