Description

Technical Field

[0001] The utility model relates to the field of small unmanned vehicle detection, in particular to a slope-adjustable combined device assembly for detecting small unmanned vehicles. Background Art

[0002] The hill climbing performance test of a micro unmanned vehicle refers to the process of evaluating the performance and ability of the vehicle when climbing a hill. This test usually involves the vehicle's hill climbing ability, stability and efficiency under different slopes and different ground conditions. Hill climbing performance is crucial for the application of unmanned vehicles in complex terrains, because the ability to climb effectively can help unmanned vehicles overcome terrain obstacles and complete tasks. Therefore, constructing a terrain scenario for the hill climbing ability test of a micro unmanned vehicle is an important part of testing and verifying the performance of unmanned vehicles.

[0003] However, the testing of micro unmanned vehicles in China is still in its early stages, and there are no corresponding standards for reference for technical requirements such as climbing ramps. Therefore, the test scene is built based on the test target: the micro unmanned vehicle is light in weight, only about 100KG, and its climbing ability under different slopes and different ground conditions. The existing traditional ramp construction method will form a combination of multiple fixed ramps, resulting in a large amount of construction work, high ramp cost, and the inability to adjust the ramp angle arbitrarily.

[0004] In this regard, an application test scenario is designed, which occupies a small space, has low cost, is easy to install and adjust, and can meet the needs of different slopes and different ground conditions; a combination device is designed to achieve a wide range of slope applications, fast adjustment speed, high ramp angle accuracy, and the ramp angle can be adjusted arbitrarily. Utility Model Content

[0005] The utility model aims to provide a slope-adjustable combined device assembly for detecting small unmanned vehicles, so as to meet the application demand of miniature unmanned vehicles for climbing ability testing application scenarios under different slopes and different ground conditions.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a slope-adjustable combination device assembly for detecting small unmanned vehicles, comprising a base with wheels installed at the bottom, a lifting mechanism installed on the top of the base, a lifting platform fixed on the top of the lifting mechanism, a ramp rotatably connected to the side end of the top of the lifting platform, an inclinometer fixed to the side end of the ramp, the inclinometer is used to display the slope of the ramp, and a roller is connected to the bottom end of the ramp.

[0007] Preferably, as an improvement, the length of the ramp is 5 m.

[0008] Preferably, as an improvement, the ramp includes a steel frame, to which a rectangular road panel with a length of 5 m is detachably connected, and rollers are rotatably connected to both sides of the lower end of the steel frame.

[0009] Preferably, as an improvement, the lifting mechanism is a hydraulic scissor fork lifting mechanism.

[0010] Preferably, as an improvement, a transition plate is fixed on the top of the lifting platform, one end of the transition plate extends out of the lifting platform and is coaxially hinged with the steel frame of the ramp, so that the transition plate and the road panel can transition smoothly.

[0011] Preferably, as an improvement, the inclinometer is a digital inclinometer.

[0012] The principle of this scheme is: in actual application, the base supports the hydraulic scissor fork lifting mechanism, which can drive the lifting platform to change height, and the transition plate on the lifting platform changes height accordingly, and then changes height with the top of the ramp through the hinge point, and the bottom of the ramp slides on the ground through rollers, so that the fixed length of the ramp changes slope, the base can flexibly move position through the wheels at the bottom, and the ramp can also flexibly move position with the base through the rollers at the bottom. After adjusting the slope of the ramp, the small unmanned vehicle to be tested drives toward the ramp according to the test procedures, and the test personnel monitor the various indicators of its climbing ability to complete the climbing ability test. The flexible and adjustable ramp angle can complete the climbing ability test of the small unmanned vehicle at different slopes through the same equipment. The digital display angle meter can provide the slope of the ramp clearly, intuitively and conveniently, which is convenient for accurately adjusting the slope of the ramp for testing. The transition plate ensures the flexibility of the ramp use process and avoids interference between the ramp and the lifting platform.

[0013] The advantages of the utility model include:

[0014] 1. Under the condition of fixed ramp length, different slopes can be adjusted arbitrarily, which improves the accuracy and speed of the adjustment angle. The ramp angle is flexibly adjustable to meet the climbing ability test of micro unmanned vehicles under different slopes.

[0015] 2. The movable structure makes the overall movement convenient and flexible, which is convenient for transfer to different sites and for testing the climbing ability under different situations.

[0016] 3. The slope is equipped with an angle meter, which, together with the hydraulic scissor fork lifting structure, can accurately control the slope and ensure the test accuracy.

[0017] 4. The overall structure is compact and occupies a small area.

[0018] 5. The slope road panel is detachable, and road panels for different road conditions can be designed and manufactured for use, so that the climbing ability under different slopes under different road conditions can be tested. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is further described in detail through specific implementation methods:

[0022] The reference numerals in the drawings of the specification include: base 1, hydraulic scissor fork lifting mechanism 2, lifting platform 3, transition plate 4, steel frame 5, road panel 6, digital display angle meter 7, roller 8, wheel 9.

[0023] The embodiment is basically as shown in the attached Figure 1 , Figure 2 As shown: A slope-adjustable combined device assembly for detecting small unmanned vehicles, including a base 1 with two sets of wheels 9 installed at the bottom, a hydraulic scissor fork lifting mechanism 2 bolted to the top of the base 1, and a rectangular lifting platform 3 bolted to the top of the hydraulic scissor fork lifting mechanism 2. A transition plate 4 is welded and fixed on the top of the lifting platform 3, and the left end of the transition plate 4 extends to the outside of the lifting platform 3 and is hingedly connected to a ramp. The ramp includes a rectangular steel frame 5 hinged to the transition plate 4, and rollers 8 are bolted to the front and rear ends of the bottom of the rectangular steel frame 5. A road panel 6 is bolted to the rectangular steel frame 5. The road panel 6 is a rectangular hard plate with a length of 5m. A digital display angle meter 7 is bonded and fixed to the side end of the road panel 6. The digital display angle meter 7 is used to display the slope of the ramp. The digital display angle meter 7 adopts an existing product available on the market.

[0024] The specific implementation process is as follows: When the climbing ability of the small unmanned vehicle is tested, the hydraulic scissor fork lifting mechanism 2 lifts the lifting platform 3 and the transition plate 4 to a preset height, so that the steel frame 5 moves with the road panel 6 to form a ramp with a specific slope. During the movement, the roller 8 provides the steel frame 5 with rolling between the ground to avoid the steel frame 5 and the road panel 6 from directly rubbing against the ground and causing wear. The slope is confirmed by observing the angle value displayed by the digital display angle meter 7, and then the small unmanned vehicle drives on the ramp, and the inspection personnel monitor its climbing ability. When it is necessary to test the climbing ability of the small unmanned vehicle under other slope conditions, there is no need to rebuild a fixed ramp with a fixed slope. It is only necessary to adjust the height of the lifting platform 3 and the transition plate 4 through the hydraulic scissor fork mechanism so that the slope formed by the steel frame 5 and the road panel 6 changes. The specific slope is obtained by observing the digital display angle meter 7. After reaching the required slope, the action of the hydraulic scissor fork lifting mechanism 2 can be stopped, and then the climbing ability test of the small unmanned vehicle under different slope conditions can be carried out. The climbing ability under different slopes under different road conditions can also be tested by disassembling and replacing road panels with different roughness or surface shapes. When the test is not needed, the lifting platform 3 and the transition plate 4 are raised by the hydraulic scissor fork lifting mechanism 2, so that the ramp formed by the steel frame 5 and the road panel 6 is close to the vertical state of 90° and is attached to the side end of the lifting platform 3, thereby reducing the space occupied by the ramp and the overall occupied space area. Then, with the help of the wheels 9 at the bottom of the base 1, it can be transferred to other sites for testing or storage. In this way, the slope-adjustable combination device assembly for testing small unmanned vehicles provided by this scheme can realize arbitrary adjustment settings of different slopes, improve the accuracy and speed of the adjustment angle, and thus meet the needs of miniature unmanned vehicles for different slopes and different ground conditions. Climbing ability test application scenarios.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
