[0001] The present invention relates to the technical field of chassis control of unmanned vehicles, and in particular to a chassis structure of an unmanned vehicle. Background Art

[0002] With the continuous advancement of science and technology, unmanned vehicle technology has received widespread attention and application. However, the existing unmanned vehicle chassis structure has problems such as insufficient driving stability and safety when dealing with complex road conditions and different loading situations.

[0003] Normally, when an unmanned vehicle is used for carrying loads, when going uphill or downhill or turning, the center of gravity will shift, which may cause the vehicle to roll over.

[0004] At the same time, in the event of a collision, the chassis's anti-collision performance is limited and cannot effectively protect the equipment inside the vehicle. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide an unmanned vehicle chassis structure that is easy to operate and use, can be counterweight adjusted, and can meet different usage needs.

[0006] In order to solve the above technical problems, the present invention provides a technical solution as follows: an unmanned vehicle chassis structure, comprising a chassis and drive wheels arranged on four sides of the chassis, wherein the drive wheels are provided with anti-slip grooves;

[0007] The head of the chassis is also connected to an anti-collision beam, and a buffer connection structure is provided between the anti-collision beam and the head of the chassis;

[0008] The top of the chassis is also concavely provided with a loading area, in which a number of evenly arranged sensing units are connected, and the lower end of the chassis is also connected with a counterweight adjustment module;

[0009] The counterweight adjustment module is in communication connection with the sensing unit. A control center is integrated at the lower end of the counterweight adjustment module. The control center reads the electrical signal change of the sensing unit and outputs a control instruction to the counterweight adjustment module.

[0010] Preferably, the sensing unit includes a load-bearing panel provided in the loading area and a weight sensing sensor provided in the load-bearing panel;

[0011] A plurality of anti-slip particles are formed on the upper surface of the bearing panel.

[0013] A plurality of pneumatic sleeves are connected to the protective shell along its width direction, and the counterweight block is slidably sleeved on the pneumatic sleeves;

[0014] The driving end of the pneumatic sleeve is fixedly connected to the counterweight block, and controls the counterweight block to move forward or backward after receiving a control instruction from a control center.

[0015] Preferably, the driving wheel is independently driven by a hub motor and includes a built-in speed sensor and torque sensor, and the control center receives feedback information from the speed sensor and the torque sensor.

[0016] Preferably, a honeycomb aluminum energy-absorbing layer coating is formed on the inner side of the anti-collision beam, and the front section of the chassis is connected to the anti-collision beam via a spring damper.

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Combined with attachment Figure 1 As shown, a chassis structure of an unmanned vehicle includes a chassis 1 and drive wheels 2 arranged on four sides of the chassis 1, and the drive wheels 2 are provided with anti-slip grooves; the head of the chassis 1 is also connected to an anti-collision beam 3, and a buffer connection structure 4 is provided between the anti-collision beam 3 and the head of the chassis 1.

[0029] When in use, a loading area 5 is recessed on the top of the chassis 1 , and a plurality of evenly arranged sensing units 6 are connected to the loading area 5 . A counterweight adjustment module 7 is also connected to the lower end of the chassis 1 .

[0030] The counterweight adjustment module 7 is communicatively connected to the sensing unit 6 , and a control center 8 is integrated at the lower end of the counterweight adjustment module 7 . The control center 8 reads the electrical signal changes of the sensing unit 6 and outputs control instructions to the counterweight adjustment module 7 .

[0031] When the present invention is implemented,

[0032] The sensing unit 6 includes a load-bearing panel 9 arranged in the loading area 5 and a weight sensing sensor 10 arranged in the load-bearing panel 9. A plurality of anti-slip particles are formed on the upper surface of the load-bearing panel 9. The load-bearing panel 9 supports the cargo, and the weight sensing sensor 10 is used to monitor the position of the cargo, thereby facilitating the control center to adjust the center of gravity.

[0033] The counterweight adjustment module 7 includes a protective shell 11 with a trapezoidal shape and a counterweight block 12 slidably arranged in the protective shell 11; a plurality of pneumatic sleeves 13 are connected to the protective shell 11 along its width direction, and the counterweight block 12 is slidably sleeved on the pneumatic sleeves 13; the driving end of the pneumatic sleeve 13 is fixedly connected to the counterweight block 12. After receiving the control command of the control center 8, the counterweight block 12 is controlled to move forward or backward. The movement of the counterweight block 12 on the left or right side can be controlled separately, thereby increasing the adaptability to the center of gravity change scenario.

[0034] The drive wheel 2 is independently driven by the hub motor 14, including a built-in speed sensor and torque sensor. The control center 8 receives feedback information from the speed sensor and torque sensor. A honeycomb aluminum energy-absorbing layer coating is formed on the inner side of the anti-collision beam 3. The front section of the chassis 1 is connected to the anti-collision beam 3 through a spring damper 15.

[0035] A contact sensor is also connected to the minimum end of the spring damper 15 to feed back a signal to the control center 8 . The control center 8 integrates a counterweight balancing model and outputs a counterweight compensation instruction according to the motion state of the chassis 1 .

[0036] When the unmanned vehicle is loaded with cargo, the weight sensor in the sensing unit monitors the weight distribution of the cargo in real time and transmits an electrical signal to the control center. The control center calculates the position of the counterweight block that needs to be adjusted based on the received electrical signal and the counterweight balancing model, and outputs a control command to the pneumatic sleeve. The pneumatic sleeve drives the counterweight block forward or backward according to the control command to adjust the center of gravity of the chassis. During driving, the speed sensor and torque sensor on the drive wheel provide real-time feedback of road conditions and driving demand information to the control center, and the control center accurately controls the speed and torque of the drive wheel based on this information.

[0037] When a collision occurs, the honeycomb aluminum energy-absorbing layer coating on the inside of the anti-collision beam absorbs and disperses the collision energy, the spring damper acts as a buffer, and the contact sensor feeds back the signal to the control center. The control center takes corresponding measures, such as emergency braking, to ensure the safety of the unmanned vehicle.
