Description

Technical Field

[0001] The present invention relates to the technical field of the wire-controlled chassis of shuttle vehicles, and specifically to a four-wheel drive and four-wheel steering wire-controlled chassis for driverless shuttle vehicles. Background Art

[0002] At present, with the development of technology and the continuous increase of labor costs, the market demand for various types of small driverless vehicles is increasing day by day. Common driverless vehicles are basically powered by batteries, with the batteries arranged on the chassis of the driverless vehicle. The chassis is connected to a wire control system, and through the pre-set route or remote control mode, operations such as automatic driving, steering, and braking of the driverless vehicle are realized. After the driverless vehicle is continuously used for a period of time, the temperature of the battery on the chassis will gradually rise, affecting the normal operation or service life of the driverless vehicle. Especially in summer, when the driverless vehicle works outdoors, there will also be situations where the driverless vehicle catches fire or even explodes due to excessive battery temperature, posing safety hazards to both people and the transported goods.

[0003] Chinese Patent with the publication number CN217969241U, a pure electric high ground clearance four-wheel drive and four-wheel steering driverless wire-controlled chassis vehicle, includes a chassis. Symmetrically arranged wheels are provided below the chassis, and the wheels are respectively connected to the chassis through suspensions. Hub motors for driving the wheels to rotate are installed between the wheels and the suspensions; the upper ends of the suspensions are rotatably connected to the vehicle body, and a steering driver for driving the suspension to rotate and thus driving the wheels to turn is also installed on the vehicle body.

[0004] In the above solution, by controlling the two-side wheels to generate different rotation speeds through the hub motors to achieve differential steering, it has the following disadvantages: no heat dissipation mechanism is provided on the chassis of the driverless vehicle, resulting in the battery pack being prone to overheating during driving, thus increasing the safety risk and further reducing the safety of the driverless vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide a four-wheel drive and four-wheel steering wire-controlled chassis for driverless shuttle vehicles to solve the problem that no heat dissipation mechanism is provided on the chassis of the driverless vehicle, resulting in the battery pack being prone to overheating during driving, thus increasing the safety risk and further reducing the safety of the driverless vehicle.

[0006] In order to achieve the above-mentioned invention objectives, the present invention adopts the following technical solutions: an unmanned shuttle bus four-wheel drive four-turn wire-controlled chassis, comprising two air inlets, both of which are opened on the front side of the chassis body, and a receiving groove is opened on the top surface of the chassis body. The air inlet is connected to the chassis body, and two air outlets are opened on the rear side of the chassis body. The air outlets are connected to the receiving groove, and the air outlets correspond to the air inlet. A plurality of placement strips are fixed to the inner bottom surface of the receiving groove, and a placement groove is opened on the top surface of the placement strip. Two arc plates are fixed to the inner bottom surface of the receiving groove, and a plurality of connecting blocks are fixed on the arc plates. Guide blocks are fixed at the four corners of the inner wall of the receiving groove.

[0007] Preferably, a first air duct is formed between the guide block and the arc plate on the left, and a second air duct is formed between the guide block and the arc plate on the right. The first air duct corresponds to the air inlet and air outlet on the left, and the second air duct corresponds to the air inlet and air outlet on the right.

[0008] Preferably, filter screens are fixed to the inner walls of the air inlet and the air outlet.

[0009] Preferably, the inner wall of the containing groove is rotatably connected to a protective plate via a hinge, and a sealing gasket is fixed to the outer wall of the protective plate, and the sealing gasket is in contact with the inner wall of the containing groove.

[0010] Preferably, installation grooves are provided on both left and right sides of the chassis body, and ultrasonic sensors are fixed to inner walls of the installation grooves.

[0011] Preferably, two connecting columns are fixed to the front side and the rear side of the chassis body, an anti-collision plate is fixed to the other end of the connecting column, and a protective pad is fixed to the anti-collision plate.

[0012] Preferably, two fixing grooves are provided on the front side of the chassis body, and vehicle lights are fixed to the inner walls of the fixing grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The heat generated by the battery pack can be absorbed by the coordination of the curved plate and the connecting block, so that the heat can be smoothly discharged to the outside of the shuttle bus under the action of the first and second air ducts, ensuring the stability of the battery pack temperature and effectively preventing the occurrence of safety accidents caused by excessive battery pack temperature, thereby significantly improving the overall safety level and actual service life cycle of the shuttle bus. The two curved plates can make the wind pass through the first and second air ducts more smoothly, so that the wind can take away the heat generated by the curved plates while flowing, ensuring that the relevant components of the shuttle bus can operate stably under appropriate temperature conditions;

[0015] II. The filter screen can block dust, sundries, etc. in the air, effectively preventing dust, sundries, etc. from entering the accommodation groove and affecting the operation of the battery pack, thus ensuring the heat dissipation and normal operation of the battery pack in the accommodation groove. The gasket can increase the sealing performance between the protective plate and the accommodation groove, effectively preventing air leakage between the protective plate and the accommodation groove, so that the air can flow through the preset channel, and further ensuring the heat dissipation efficiency of the battery pack. The ultrasonic sensor can monitor the obstacle conditions in front of, behind and on both sides of the shuttle vehicle in real time, providing a basis for the path planning and decision-making of the shuttle vehicle. When an obstacle is detected, the shuttle vehicle can automatically adjust its driving direction or speed according to information such as the position, distance and size of the obstacle, perform an avoidance action, and ensure driving safety;

[0016] III. Through the cooperation of the anti-collision plate and the protective pad, the energy generated during the collision of the shuttle vehicle can be absorbed, preventing the collision from damaging the shuttle vehicle, thus protecting the important components at the front of the shuttle vehicle and extending its service life. The vehicle lamp can provide lighting for the shuttle vehicle at night or under low light conditions, allowing other vehicles and pedestrians to notice the presence of the shuttle vehicle, thereby reducing the occurrence of traffic accidents. Through the snap connection setting of the snap connection posts and the snap connection grooves, the assembly and disassembly between the load-bearing base and the chassis body can be facilitated, improving the convenience of maintaining the chassis body.

Detailed implementation manner

[0025] The following will, with reference to the accompanying drawings, give a detailed description of the preferred embodiments of the present invention.

[0026] As Figures 1 - 3 and Figure 7 shown, a four-wheel drive and four-steering wire-controlled chassis for a driverless shuttle bus includes two air inlets 1, both of the two air inlets 1 are opened on the front side of the chassis body 2, a receiving groove 3 is opened on the top surface of the chassis body 2, the air inlet 1 is communicated with the chassis body 2, two air outlets 4 are opened on the rear side of the chassis body 2, the air outlet 4 is communicated with the receiving groove 3, the air outlet 4 corresponds to the air inlet 1, a plurality of placing strips 5 are fixed on the inner bottom surface of the receiving groove 3, placing grooves 6 are opened on the top surface of the placing strips 5, two arc plates 7 are fixed on the inner bottom surface of the receiving groove 3, a plurality of connecting blocks 8 are fixed on the arc plates 7, and the arc plates 7 and the connecting blocks 8 are both made of copper. Flow guiding blocks 9 are fixed at the four corners of the inner wall of the receiving groove 3. A first air duct 901 is formed between the left flow guiding block 9 and the arc plate 7, and a second air duct 902 is formed between the right flow guiding block 9 and the arc plate 7. The first air duct 901 corresponds to the left air inlet 1 and the air outlet 4, and the second air duct 902 corresponds to the right air inlet 1 and the air outlet 4.

[0027] During use, during the driving process of the shuttle bus, air will smoothly flow into the inside of the receiving groove 3 from the air inlet 1 under the driving of the inertial force of the shuttle bus. Thereafter, the air will flow respectively through the first air duct 901 and the second air duct 902 according to the established path. When the shuttle bus continuously maintains a moving state, the air flow will carry the heat absorbed by the arc plates 7 and the connecting blocks 8 from the battery pack (not shown in the figure) and steadily flow to the position of the air outlet 4 until it is discharged outside the shuttle bus, thereby achieving the effect of maintaining the battery pack temperature in a stable state;

[0028] Through the cooperation of the arc plates 7 and the connecting blocks 8, the heat generated by the battery pack can be absorbed, so that the heat can be smoothly discharged outside the shuttle bus under the action of the first air duct 901 and the second air duct 902, ensuring the stability of the battery pack temperature and effectively preventing the occurrence of safety accidents caused by too high battery pack temperature, thereby significantly improving the overall safety level and actual service life cycle of the shuttle bus;

[0029] The wind can pass through the first air duct 901 and the second air duct 902 more smoothly through the two arc-shaped plates 7, so that the wind can take away the heat generated by the arc-shaped plates 7 while flowing, ensuring that the relevant components of the shuttle vehicle can operate stably under suitable temperature conditions.

[0030] Such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, filter nets 10 are fixedly arranged on the inner walls of the air inlet 1 and the air outlet 4. A protection plate 11 is rotatably connected to the inner wall of the accommodation groove 3 through a hinge. A sealing gasket 12 is fixedly arranged on the outer wall of the protection plate 11, and the sealing gasket 12 is in contact with the inner wall of the accommodation groove 3. Installation grooves 13 are formed on both the left and right sides of the chassis body 2, and ultrasonic sensors 14 are fixedly arranged on the inner walls of the installation grooves 13.

[0031] During use, the filter net 10 can block dust, sundries, etc. in the air, effectively preventing dust, sundries, etc. from entering the accommodation groove 3 and affecting the operation of the battery pack, thereby ensuring the heat dissipation and normal operation of the battery pack in the accommodation groove 3. The sealing gasket 12 can increase the sealing performance between the protection plate 11 and the accommodation groove 3, effectively preventing air leakage between the protection plate 11 and the accommodation groove 3, so that the air can flow through the preset channel, and further ensuring the heat dissipation efficiency of the battery pack. The ultrasonic sensor 14 can monitor the obstacle conditions in front of, behind, and on both sides of the shuttle vehicle in real time, providing a basis for the path planning and decision-making of the shuttle vehicle. When an obstacle is detected, the shuttle vehicle can automatically adjust the driving direction or speed according to information such as the position, distance, and size of the obstacle to achieve an avoidance action and ensure driving safety.

[0032] Such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, two connecting columns 15 are fixedly arranged on the front side and the rear side of the chassis body 2. The other ends of the connecting columns 15 are fixedly provided with anti-collision plates 16, and a protection pad 1601 is fixedly arranged on the anti-collision plates 16. Two fixing grooves 17 are formed on the front side of the chassis body 2, and vehicle lamps 18 are fixedly arranged on the inner walls of the fixing grooves 17. Clamping grooves 19 are formed at the four corners on the top surface of the chassis body 2. A load-bearing base 20 is arranged on the top surface of the chassis body 2. Clamping columns 21 are fixedly arranged at the four corners on the bottom surface of the load-bearing base 20, and the clamping columns 21 are clamped with the clamping grooves 19.

[0033] In use, through the cooperation of the anti-collision plate 16 and the protective pad 1601, the energy generated during the collision of the shuttle car can be absorbed, preventing damage to the shuttle car caused by the collision, thereby protecting the important components at the front of the shuttle car and extending its service life. Through the vehicle lamp 18, illumination can be provided for the shuttle car at night or under low light conditions, enabling other vehicles and pedestrians to notice the presence of the shuttle car, thus reducing the occurrence of traffic accidents. Through the snap connection between the snap post 21 and the snap groove 19, the assembly and disassembly of the load-bearing base 20 and the chassis body 2 can be facilitated, improving the convenience of maintaining the chassis body 2.
