After the connectors of the test box and the vehicle instrument are docked, the test can be performed. However, when the engineering vehicle is traveling on uneven terrain, it will shake frequently, which requires a high stability of the engineering vehicle instrument. The prior art lacks a device for performing performance testing and shaking on the engineering vehicle instrument. Therefore, the present application provides an engineering vehicle instrument testing device. Utility Model Content

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an engineering vehicle instrument testing device, comprising a base, an operating table arranged above the base, a connecting column fixed between the bottom of the operating table and the top of the base, a disc arranged above the operating table, a horizontal plate arranged above the disc, and a clamping assembly arranged on the top of the horizontal plate and used to clamp the engineering vehicle instrument to be tested, the top of the base is provided with an instrument tester for testing the engineering vehicle instrument to be tested and a lower driving assembly for driving the disc to rotate, the top of the operating table is provided with multiple groups of hinge assemblies for movably connecting the operating table and the horizontal plate and an upper driving assembly for driving the horizontal plate to intermittently shake, and the multiple groups of hinge assemblies are evenly distributed about the axis of the disc.

[0006] By adopting the above technical scheme, the clamping assembly clamps the engineering vehicle instrument to be tested, the lower driving assembly can drive the disc to rotate, and the upper driving assembly can drive the cross plate to shake intermittently, simulating the bumpy environment of the engineering vehicle during driving. The instrument tester is connected to the engineering vehicle instrument to be tested through the connecting line connector, so as to test the engineering vehicle instrument to be tested, screen out the engineering vehicle instruments that meet the bumpy requirements, and ensure the quality of the engineering vehicle instruments leaving the factory.

[0007] Furthermore, the hinge assembly includes a first connecting rod hinged to the top of the operating table and a second connecting rod hinged to an end of the first connecting rod away from the operating table, and the upper end of the second connecting rod is hinged to the bottom of the cross plate.

[0009] Furthermore, the upper driving assembly includes a vertical plate fixed on a position of the disc near its edge, an upper motor fixed on the vertical plate, and a cam fixed to the output end of the upper motor, wherein the side of the cam away from the upper motor intermittently lifts the bottom of the cross plate, and the distance between the side of the cam away from the upper motor and the output shaft of the upper motor is greater than the distance between the output shaft of the upper motor and the top of the disc.

[0010] By adopting the above technical solution, the upper motor drives the cam to rotate after working, and the side of the cam away from the upper motor intermittently lifts the bottom of the cross plate. The lower driving assembly can drive the disc to rotate, so that the cam can lift different positions of the bottom of the cross plate, simulating the bumpy feeling of the engineering vehicle during driving and improving the accuracy of the test results.

[0012] By adopting the above technical solution, the lower motor drives the driving gear to rotate after it starts working. After the driving gear rotates, it drives the driven gear, the rotating shaft fixed to the driven gear, and the disk at the upper end of the rotating shaft to rotate. The cam in the upper drive assembly cooperates to intermittently lift different parts of the bottom of the cross plate, simulating the bumpy feeling during the driving of the engineering vehicle.

[0017] Furthermore, a rubber plate is fixed to one side of the two clamping plates that are close to each other.

[0018] By adopting the above technical solution, the rubber sheet is made of rubber material with good elasticity. When the clamping plates on both sides cooperate and clamp the engineering vehicle instrument to be tested, the rubber sheet reduces the probability of the engineering vehicle instrument to be tested being pinched.

[0019] Furthermore, two pads are fixed on the top of the transverse plate, both of which are located between the guide rod and the threaded rod, and the tops of the pads are in contact with the instrument of the engineering vehicle to be detected.

[0020] By adopting the above technical solution and setting of the pad, a good supporting effect is played on the engineering vehicle instrument to be tested, and the stability of the engineering vehicle instrument to be tested being clamped during the bumping process is enhanced.

DETAILED DESCRIPTION

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the embodiment of the present application discloses an engineering vehicle instrument test device, including a base 1, an operating table 2, a disc 3, a lower drive assembly 4, a horizontal plate 5, a hinge assembly 6, a clamping assembly 7 and an upper drive assembly 8. The operating table 2 is a circular plate-shaped structure, which is arranged above the base 1. A connecting column 21 fixed to the top of the base 1 is fixed at the bottom of the operating table 2. A plurality of connecting columns 21 are provided and are evenly distributed about the axis of the operating table 2. A circular through hole 22 is provided through the operating table 2.

The lower driving assembly 4 includes a lower motor 41 fixed to the top of the base 1, a driving gear 42 fixed to the output end of the lower motor 41, a rotating shaft 43 rotatably installed on the top of the base 1, and a driven gear 44 fixedly sleeved on the rotating shaft 43 and meshing with the driving gear 42. The upper end of the rotating shaft 43 is fixed to the bottom of the disc 3.

[0032] The horizontal plate 5 is arranged above the disc 3, and the hinge assembly 6 is arranged on the top of the operating table 2, which is used to movably connect the operating table 2 with the horizontal plate 5. The hinge assembly 6 is provided with multiple groups and is evenly distributed about the axis of the disc 3. The hinge assembly 6 includes a first connecting rod 61 hinged to the top of the operating table 2 and a second connecting rod 62 hinged to an end of the first connecting rod 61 away from the operating table 2. The upper end of the second connecting rod 62 is hinged to the bottom of the horizontal plate 5.

[0033] Two symmetrically arranged first fixing blocks 51 and two symmetrically arranged second fixing blocks 52 are fixed on the top of the cross plate 5. The clamping assembly 7 is arranged on the top of the cross plate 5 and is used to clamp the engineering vehicle instrument 9 to be inspected. The clamping assembly 7 includes a threaded rod 71 rotatably installed between the two first fixing blocks 51, a guide rod 72 fixed between the two second fixing blocks 52, a driving motor 73 fixed on one of the first fixing blocks 51 and used to drive the threaded rod 71, and a clamping plate 74 jointly arranged on the threaded rod 71 and the guide rod 72. The threaded rod 71 is provided with two sections of external threads with equal pitch and opposite rotation direction. The threaded rod 71 passes through the clamping plate 74 and is threadedly connected with the clamping plate 74. The guide rod 72 passes through the clamping plate 74 and slides with the clamping plate 74. The clamping plate 74 is provided with two and is symmetrically distributed on the two sections of threads of the threaded rod 71. In this embodiment, an instrument tester 14 for testing the engineering vehicle instrument 9 to be tested is arranged on the top of the base 1, an upper battery 31 and an upper controller 32 electrically connected to the upper motor 82 are fixed on the top of the disc 3, a lower battery 11 and a lower controller 12 electrically connected to the lower motor 41 are fixed on the top of the base 1, a display 13 electrically connected to the instrument tester 14 is also fixed on the top of the base 1, and the drive motor 73 is electrically connected to the lower battery 11.

[0034] The upper driving assembly 8 is arranged on the top of the operating table 2, and is used for driving the horizontal plate 5 to shake intermittently. The upper driving assembly 8 includes a vertical plate 81 fixed on a position of the disc 3 near its edge, an upper motor 82 fixed on the vertical plate 81, and a cam 83 fixed on the output end of the upper motor 82. The side of the cam 83 away from the upper motor 82 intermittently lifts the bottom of the horizontal plate 5, and the distance between the side of the cam 83 away from the upper motor 82 and the output shaft of the upper motor 82 is greater than the distance between the output shaft of the upper motor 82 and the top of the disc 3 (due to angle reasons, in the figure, the distance between the side of the cam 83 away from the upper motor 82 and the output shaft of the upper motor 82 appears to be smaller than the distance between the output shaft of the upper motor 82 and the top of the disc 3).

[0035] In order to enhance the protection of the engineering vehicle instrument 9 to be tested during the clamping process, a rubber plate 741 is fixed to the side of the two clamping plates 74 close to each other. In order to enhance the stability of the engineering vehicle instrument 9 to be tested during the clamping process, two pads 53 are fixed to the top of the cross plate 5, both of which are located between the guide rod 72 and the threaded rod 71, and the top of the pad 53 abuts against the engineering vehicle instrument 9 to be tested.

[0036] The use principle of a test device for engineering vehicle instruments in this embodiment is as follows: after the driving motor 73 works, it drives the threaded rod 71 to rotate. Since the two clamping plates 74 are both threadedly connected to the threaded rod 71, the clamping plates 74 and the guide rod 72 slide and cooperate, so that the clamping plates 74 on both sides are close to or away from each other, thereby clamping the engineering vehicle instrument 9 to be tested, and enhancing the stability of the engineering vehicle instrument 9 to be tested during the bumping process. The top of the operating table 2 and the bottom of the cross plate 5 are hinged by the first connecting rod 61 and the second connecting rod 62, and multiple groups of hinge components 6 cooperate to enable the cross plate 5 to simulate a bumpy environment under the action of the upper driving component 8. The instrument tester 14 is connected to the engineering vehicle instrument 9 to be tested through a connecting line connector, so as to test the engineering vehicle instrument 9 to be tested, select the engineering vehicle instruments that meet the bumping requirements, and ensure the quality of the engineering vehicle instruments shipped from the factory. After the upper motor 82 starts working, it drives the cam 83 to rotate. The side of the cam 83 away from the upper motor 82 intermittently lifts the bottom of the cross plate 5. The lower driving assembly 4 can drive the disc 3 to rotate, so that the cam 83 lifts different positions of the bottom of the cross plate 5, simulating the bumpy feeling during the driving of the engineering vehicle and improving the accuracy of the test results.

[0037] Example 2

[0038] like Figure 2As shown, the difference between this embodiment and embodiment 1 is that: there are two groups of upper drive components 8, and the cams 83 in the two groups of upper drive components 8 intermittently lift the bottom surface of the cross plate 5. In the process that one of the cams 83 lifts the bottom of the cross plate 5 on the side away from the upper motor 82, the other cam 83 is separated from the bottom of the cross plate 5 on the side away from the upper motor 82, which increases the frequency of the bumping of the cross plate 5 and simulates a more severe bumping environment than embodiment 1, which is conducive to improving the objectivity of the test results.

[0039] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
