[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like Figures 1 to 4As shown, a front suspension system for a high-performance intelligent mobile platform includes a front suspension system 02, which is installed to the front end of the chassis frame of the high-performance intelligent mobile platform 01, one side of the front suspension system 02 is connected to the frame 03, and a brake system 05 is also installed at one end of the front wheel assembly 04 of the front suspension system 02.

[0026] like Figure 1 , Figure 4 As shown, this embodiment provides a front suspension system for a high-performance intelligent mobile platform. The front suspension system 02 is installed at the front end of the chassis frame of the high-performance intelligent mobile platform 01, and integrates suspension, steering and braking functions.

[0027] like Figure 2 As shown: the front suspension system 02 is composed of a front suspension body, a front suspension swing arm 0201, a swing arm latch 0202, a cylinder base 0203, a cylinder body 0204, a cylinder support 0205, a steering electric push cylinder 0206, an electric push cylinder connecting seat 0207, a tie rod support 0208, a guide column 0209, a tie rod body 0210, a tie rod connecting seat 0211, a steering kingpin 0212 and a front wheel assembly 04.

[0028] Among them, the cylinder body 0204 is installed on the front suspension body through the cylinder base 0203, and the cylinder body 0204 is installed on the frame 03 through the cylinder support 0205. The air circuit system provides power for the suspension lifting function, and the front suspension swing arm 0201 and the swing arm latch 0202 perform the suspension vertical lifting function. Specifically, the air circuit system provides power for the suspension lifting function. When the air pressure in the cylinder body 0204 increases, the cylinder support 0205 opens the front suspension body and the frame 03 through the cylinder base 0203, and the distance between the front suspension body and the frame 03 increases. Then, the front suspension body increases the distance between the front wheel assembly 04 and the body of the high-performance intelligent mobile platform through the front suspension swing arm 0201 and the swing arm latch 0202, that is, the height of the high-performance intelligent mobile platform increases, and vice versa, the height decreases, thereby achieving The lifting and lowering of the high-performance intelligent mobile platform body. In addition, it should be noted that the chassis of the high-performance intelligent mobile platform 01 is separable from the high-performance intelligent mobile platform body, while the frame 03 is integrated with the chassis of the high-performance intelligent mobile platform 01, so that when the cylinder support 0205 opens the frame 03 through the cylinder base 0203, the chassis of the high-performance intelligent mobile platform 01 is then separated from the high-performance intelligent mobile platform body above the front suspension body. In addition, in order to avoid interfering with the lifting and lowering of the high-performance intelligent mobile platform body, one side of the front suspension swing arm 0201 is softly connected to the frame 03 through the swing arm pin 0202. Specifically, the front suspension swing arm 0201 and the swing arm pin 0202 can be connected to the frame 03 by flexible elements, etc., so as to avoid interfering with the cylinder support 0205 in opening the front suspension body and the frame 03.

[0029] Among them, the steering electric push cylinder 0206 is installed on the front suspension body through the electric push cylinder connecting seat 0207. The steering electric push cylinder 0206 is connected to the front wheel assembly 04 through the tie rod support 0208, the guide column 0209, the tie rod body 0210, the tie rod connecting seat 0211, and the steering kingpin 0212.

[0030] like Figure 3 As shown: the front wheel assembly 04 includes a shaft end stopper 0401, a transmission shaft 0402, a coupling 0403, a bearing 0404, a kingpin seat 0405, a wheel hub 0406, a tire 0407 and a tire stopper 0408, wherein the tire stopper 0408 is installed on one side of the tire 0407, the tire 0407 is connected to one end of the wheel hub 0406, the kingpin seat 0405 is installed in the middle of the wheel hub 0406, the other end of the wheel hub 0406 is connected to the transmission shaft 0402 through the coupling 0403 and the bearing 0404, the shaft end of the transmission shaft 0402 is installed with a shaft end stopper 0401, and the shaft end of the transmission shaft 0402 is also connected to the brake system 05.

[0031] like Figure 4 As shown: the braking system 05 is composed of brake pads 0501, caliper mounting blocks 0502, brake calipers 0503, and hydraulic upper pumps 0504.

[0032] Among them, the brake pad 0501 is installed on the shaft end of the front wheel assembly 04, one end of the caliper mounting block 0502 is connected to the front suspension system 02, and the other end is connected to the brake caliper 0503, and the hydraulic upper pump 0504 is installed at the specified position of the frame 03. The hydraulic upper pump 0504 provides the power system required for braking, and the brake caliper 0503 performs the braking function.

[0033] Advantages of the utility model: The mechanism is easy to install, and the front suspension structure can also be applied to the rear suspension of high-performance intelligent mobile platforms and other industrial equipment. As an important test equipment for real vehicle testing, the high-performance intelligent mobile platform improves its reliability and practicality, which has comprehensive economic benefits in terms of maintenance of test equipment.

[0034] Working principle of a front suspension system for a high-performance intelligent mobile platform:

[0035] The front suspension system integrates suspension, steering and braking functions. When the device is moving, damage to the ground, foreign objects, etc. will cause the platform vehicle to vibrate. The front wheel assembly 04 is connected to the front suspension swing arm 0201 through the swing arm latch 0202. One end of the front suspension swing arm 0201 is hinged to the other end on the frame 03 and connected to the cylinder base 0203. The cylinder body 0204 is installed on the front suspension system 02 through the cylinder base 0203. When the front wheel assembly 04 vibrates, the vibration is transmitted to the cylinder base 0203. At this time, the cylinder body 0204 absorbs part of the vibration by compressing the internal gas, thereby reducing the vibration transmitted to the front suspension system 02 and playing a shock absorbing role;

[0036] When the platform needs to change its driving direction, the steering electric push cylinder 0206 installed on the front suspension system 02 receives the execution command of the platform, and the steering electric push cylinder 0206 pushes the tie rod support 0208 to move left and right along the guide column 0209, thereby pushing the tie rod body 0210 to move, and the tie rod body 0210 drives the tie rod connecting seat 0211 to move, and the tie rod connecting seat 0211 is fixedly connected to the front wheel assembly, so that the movement of the tie rod connecting seat 0211 drives the front wheel assembly 04 to rotate around the steering kingpin 0212, thereby realizing the steering of the platform vehicle.

[0037] When the platform vehicle needs to slow down or stop, the brake system comes into play. The hydraulic upper pump 0504 increases pressure after receiving the command, and the hydraulic pressure is transmitted to the brake caliper 0503, and the brake caliper 0503 clamps the brake pad 0501. Since the brake pad 0501 is installed at the rear end of the front wheel assembly 04, the brake pad 0501 is clamped to achieve the deceleration of the wheel and thus the deceleration or stop of the platform vehicle.

[0038] Example 1

[0039] Reference Figure 1 The internal layout of the front suspension system is shown. Figure 2 It is a front suspension system structure. This device structure can change the size ratio to be used as a high-performance intelligent platform of different sizes. In the actual platform layout, the suspension system can be consistent front and rear, or it can be used only for front suspension or only for rear suspension. This mechanism can also be used with other mobile platform devices.

[0040] It should be noted that the present application does not improve the control program, and the control program and electrical components involved are all prior art.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
