Description

Technical Field

[0001] This utility model belongs to the field of braking device technology, specifically relating to a universal chassis suitable for complex terrain. Background Technology

[0002] A general-purpose chassis is the basic platform for robot movement and operation. However, most existing general-purpose robot chassis are designed for relatively flat and regular environments such as factory buildings, which makes it difficult to meet the needs of use in complex terrains. Specifically:

[0003] Existing general-purpose chassis are designed with a high center of gravity to protect internal electrical components. However, in complex terrains, such as rugged mountains, muddy construction sites, or obstacle-filled ruins, robots are prone to tipping over due to instability during movement, resulting in damage. Most existing general-purpose chassis lack effective cushioning mechanisms, failing to absorb impacts from bumpy surfaces. This leads to significant impacts on the chassis structure, potentially causing loosening and damage to chassis components over time, reducing the chassis's lifespan. Furthermore, frequent bumps can affect the accuracy of mounted equipment, even damaging it and hindering normal robot operation. Finally, most existing general-purpose chassis lack real-time surveying capabilities, failing to anticipate terrain obstacles, ground materials, and potential hazards.

[0004] In other words, existing general-purpose robot chassis have many shortcomings when facing complex terrain, such as high center of gravity, lack of buffering capacity, real-time surveying capability, and emergency power supply function, making it difficult to meet the growing demand for operations in complex environments. Utility Model Content

[0005] The purpose of this invention is to provide a universal chassis suitable for complex terrain, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a universal chassis suitable for complex terrain, comprising a base plate and an outer shell, wherein the base plate is provided on the lower part of the inner wall of the outer shell, and universal wheels are provided at the four corners of the bottom of the base plate. Mounting grooves are provided on the left and right sides of the base plate, and a mounting plate is connected between the mounting grooves and the top of the inner wall of the outer shell. A drive wheel is slidably mounted on the inner side of the mounting plate. A base plate is provided extending upward from the rear side of the top of the outer shell, and an interface is provided on the top of the base plate. A left scanning area and a right scanning area are provided between the base plate and the outer shell. A unidirectional lidar is provided on the top of the outer shell at a position between the left scanning area and the right scanning area.

[0007] Preferably, each mounting plate is provided with a mounting frame, the mounting frame is symmetrically provided with slide rails, the slide rails are provided with sliders, the outer sides of the sliders are connected with mounting blocks, and the outer sides of the mounting blocks are provided with drive wheels for rotation.

[0008] Preferably, a buffer spring is connected between the mounting block and the inner wall of the mounting frame.

[0009] Preferably, the front side of the housing is recessed with an inclined groove plate, and a depth camera is mounted on the inclined groove plate.

[0010] Preferably, a battery module is slidably provided on the rear side of the outer casing, and two charging contacts are provided on the rear side of the battery module. A circular groove is opened on the rear side of the battery module at the position on both sides of the charging contacts, and a carrying component is rotatably provided in the circular groove.

[0011] Preferably, the battery module has a triangular connector on the rear side, and a protective plug is provided on the outside of the triangular connector.

[0012] Preferably, the inner wall of the outer shell is provided with a reinforcing rib at a position below the bottom plate, and a reinforcing beam is connected between the front and rear sides of the inner wall of the outer shell, the reinforcing beam being located below the bottom plate.

[0013] Preferably, the outer side of the drive wheel is provided with anti-slip patterns.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The base plate of this utility model is embedded in the lower part of the inner wall of the outer shell, which pulls down the center of gravity of the chassis when it moves, effectively reducing the risk of shaking and overturning caused by complex terrain. At the same time, reinforcing ribs and reinforcing beams are set under the base plate to further enhance the load-bearing capacity of the base plate, enabling it to withstand greater weight and impact force. This ensures that the chassis will not undergo structural deformation or damage during complex terrain and long-term use, thereby extending the service life of the chassis and ensuring its long-term stable operation.

[0016] The drive wheel in this invention can also move up and down, enabling it to adapt to complex terrain. When the chassis is traveling on a bumpy road, the drive wheel can automatically adjust its height to reduce direct impact caused by height differences, effectively protecting the drive wheel and drive components from damage. At the same time, a buffer spring is installed between the drive wheel and the base plate to provide further buffering for the up and down movement of the drive wheel, reducing the impact of bumpy road conditions on the drive wheel and the entire chassis, thereby ensuring the service life of the drive wheel and the entire chassis.

[0017] This invention achieves comprehensive and real-time acquisition of road conditions by installing a unidirectional lidar and a depth camera. The depth camera can capture the depth information of objects in front, supplementing and improving the scanning data of the lidar, enabling it to detect potential dangers and obstacles in complex terrain in a timely manner and react in advance.

[0018] The battery module installed on the rear side of this utility model can not only power itself, but also has a specially designed three-prong plug. Users can use this three-prong plug to power or charge other devices in an emergency. For example, it can provide power support for mobile phones, walkie-talkies and other devices when working in the field, which greatly improves the emergency support capability of the chassis.

[0027] Example 1

[0028] like Figures 1 to 6 The chassis shown is suitable for complex terrain and includes a base plate 1 and an outer shell 2. The base plate 1 is located on the lower part of the inner wall of the outer shell 2. Universal wheels 3 are located at the four corners of the bottom of the base plate 1. Mounting grooves 4 are opened on the left and right sides of the base plate 1. Mounting plates 5 are connected between the mounting grooves 4 and the top of the inner wall of the outer shell 2. Drive wheels 6 are slidably mounted on the inner side of the mounting plates 5. A base plate 7 extends upward from the rear top of the outer shell 2. An interface 8 is opened on the top of the base plate 7. A left scanning area 9 and a right scanning area 10 are provided between the base plate 7 and the outer shell 2. A unidirectional lidar 11 is located on the top of the outer shell 2 between the left scanning area 9 and the right scanning area 10. Mounting frames 12 are provided inside the mounting plates 5. Slide rails 13 are symmetrically arranged on the mounting frames 12. Slider blocks 14 slide on the slide rails 13. Mounting blocks 1 are connected to the outer sides of the sliders 14. 5. A drive wheel 6 is rotatably mounted on the outer side of the mounting block 15; a buffer spring 17 is connected between the mounting block 15 and the inner wall of the mounting frame 12; an inclined groove plate 18 is recessed on the front side of the outer shell 2, and a depth camera 19 is mounted on the inclined groove plate 18; a battery module 20 is slidably mounted on the rear side of the outer shell 2, and two charging contacts 21 are provided on the rear side of the battery module 20. A circular groove 22 is opened on both sides of the electrodes on the rear side of the battery module 20, and a carrying component 23 is rotatably mounted in the circular groove 22; a triangular plug 24 is also opened on the rear side of the battery module 20, and a protective plug 25 is provided on the outer side of the triangular plug 24; a reinforcing rib 26 is provided on the inner wall of the outer shell 2 below the base plate 1, and a reinforcing beam 27 is connected between the front and rear sides of the inner wall of the outer shell 2, and the reinforcing beam 27 is located below the base plate 1; an anti-slip pattern 28 is provided on the outer side of the drive wheel 6.

[0029] The base plate 1 of this invention is embedded in the lower part of the inner wall of the outer shell 2, which lowers the center of gravity of the chassis when it moves, effectively reducing the risk of swaying and overturning caused by complex terrain. Reinforcing ribs 26 and reinforcing beams 27 are also installed below the base plate 1, further enhancing its load-bearing capacity. This allows the base plate 1 to withstand greater weight and impact, ensuring that the chassis will not deform or be damaged during complex terrain and long-term use, thereby extending the chassis's service life and ensuring its long-term stable operation. The drive wheel 6 in this invention can also move up and down, enabling adaptive functionality to complex terrain. When the chassis travels on bumpy roads, the drive wheel 6 can automatically adjust its height, reducing direct impact caused by height differences and effectively protecting the drive wheel 6 and drive components from damage. A buffer spring is also installed between the drive wheel 6 and the base plate 1. 17. This provides further cushioning for the vertical movement of the drive wheel 6, reducing the impact of bumpy road conditions on the drive wheel 6 and the entire chassis, thereby ensuring the service life of the drive wheel 6 and the entire chassis. This invention, by installing a unidirectional lidar 11 and a depth camera 19, achieves comprehensive, real-time acquisition of road conditions. The depth camera 19 can capture the depth information of objects ahead, supplementing and improving the lidar's scanning data, enabling it to promptly detect potential dangers and obstacles in complex terrain and react in advance. The battery module 20 installed at the rear of this invention not only provides power to itself but also features a specially designed triangular socket 24. Users can use this socket 24 to power or urgently charge other devices, such as providing power to mobile phones, walkie-talkies, and other devices during field operations, greatly improving the chassis's emergency response capabilities.

[0030] Example 2

[0031] like Figures 1 to 6 The diagram shows a general-purpose chassis suitable for complex terrain, comprising a base plate 1 and an outer shell 2. The base plate 1 is located on the lower part of the inner wall of the outer shell 2, i.e., the base plate 1 is embedded in the lower part of the inner wall of the outer shell 2. When a moving component, such as a caster wheel 3 or a drive wheel 6, is installed on the base plate 1, the center of gravity of the entire chassis can be lowered during movement. The lower center of gravity makes the chassis more stable during movement, effectively reducing the risk of shaking and overturning caused by complex terrain. It ensures that the chassis can maintain a stable movement on rugged and undulating complex terrain, thus adapting to various complex and changing terrain environments.

[0032] Since many components need to be installed on the base plate 1, such as casters 3, drive wheels 6, and battery modules 20, the weight of these components and the forces generated during operation will place high demands on the structural strength of the base plate 1 and the outer shell 2. In order to ensure the overall structural stability and reliability of the chassis, a reinforcing rib 26 is provided on the inner wall of the outer shell 2 below the base plate 1. The reinforcing rib 26 strengthens the connection between the edge of the base plate 1 and the outer shell 2. At the same time, a reinforcing beam 27 is connected between the front and rear sides of the inner wall of the outer shell 2. The reinforcing beam 27 is located below the base plate 1, which further enhances the load-bearing capacity of the base plate 1, enabling the base plate 1 to withstand greater weight and impact, ensuring that the chassis will not undergo structural deformation or damage during complex terrain and long-term use, thereby extending the service life of the chassis and ensuring its long-term stable operation.

[0033] The chassis 1 has four casters 3 at its bottom corners, which can rotate freely in all directions, allowing the chassis to move easily in all directions. It can easily handle straight driving and turning, greatly improving the chassis's maneuverability in complex terrain. At the same time, mounting slots 4 are provided on the left and right sides. Mounting plates 5 are connected between the mounting slots 4 and the top of the inner wall of the outer shell 2. Drive wheels 6 are slidably mounted on the inner side of the mounting plates 5. The drive wheels 6 rotate under the action of the driving components, and the chassis can change direction by the speed difference between the two drive wheels 6. This configuration allows the chassis to flexibly adjust its driving direction according to the actual road conditions when facing complex terrain, easily cope with various complex terrain changes, and ensure that the chassis always moves along the optimal path.

[0034] Considering that there may be areas with large elevation differences in complex terrain, such as rugged mountain roads and potholed ground, these bumpy road conditions will have a large impact on the drive wheels 6 and drive components. Therefore, mounting frames 12 are also provided in the mounting plate 5. Slide rails 13 are symmetrically provided on the mounting frames 12, and sliders 14 are slidably provided on the slide rails 13. Mounting blocks 15 are connected to the outer sides of the sliders 14, that is, the mounting blocks 15 can move up and down on the left and right sides of the chassis. In this way, the drive wheels 6, which are rotatably set on the outer side of the mounting blocks 15, can also move up and down. In this way, the drive wheels 6 can move up and down according to the actual road conditions, thereby realizing the adaptive function of complex terrain.

[0035] When the chassis is traveling on bumpy roads, the drive wheel 6 can automatically adjust its height to reduce direct impact caused by height differences, effectively protecting the drive wheel 6 and drive components from damage. At the same time, a buffer spring 17 is connected between the mounting block 15 and the inner wall of the mounting frame 12 to provide further buffering for the up and down movement of the drive wheel 6, reducing the impact of bumpy road conditions on the drive wheel 6 and the entire chassis, thereby ensuring the service life of the drive wheel 6 and the entire chassis, and ensuring that the chassis maintains good performance during long-term use.

[0036] Furthermore, anti-slip patterns 28 are provided on the outer side of the drive wheel 6 to ensure that the chassis can maintain good grip and stability under such wet and slippery conditions. The anti-slip patterns 28 increase the friction between the drive wheel 6 and the ground, effectively preventing the chassis from slipping on wet and slippery ground, thereby ensuring that the chassis can move reliably under various complex terrain conditions, and improving the chassis' passability and safety.

[0037] Example 3

[0038] like Figures 1 to 6 The diagram shows a universal chassis suitable for complex terrain. The outer shell 2 has a base plate 7 extending upward from the top rear side. The top of the base plate 7 has an interface 8 for mounting robots or other mobile devices and for signal connection after installation. The chassis can be seamlessly connected to various devices through the mounting holes on the base plate 7, making the chassis a universal mobile platform. At the same time, the interface 8 provides stable mobility support and reliable signal transmission for different devices, greatly expanding the application range and usage scenarios of the chassis, enabling it to meet different operational needs under various complex terrain conditions.

[0039] Furthermore, in order to enable the chassis to understand the road conditions ahead in real time and make corresponding adjustments, a left scanning area 9 and a right scanning area 10 are set between the base plate 7 and the outer shell 2. At the same time, a unidirectional lidar 11 is set on the top of the outer shell 2 between the left scanning area 9 and the right scanning area 10. The unidirectional lidar 11 can scan a large area of ​​the road conditions ahead, quickly obtain road condition information, including the position, distance, and shape of obstacles, and plan the best movement path in advance based on the scanned road condition data to avoid obstacles and ensure that the chassis can drive safely and efficiently in complex terrain.

[0040] Furthermore, the front side of the outer shell 2 is recessed with an inclined groove plate 18, on which a depth camera 19 is mounted. The inclined angle of the inclined groove plate 18 is 45°. In conjunction with the aforementioned unidirectional lidar 11, it enables all-round, real-time acquisition of road conditions. The depth camera 19 can capture the depth information of objects in front, further supplementing and improving the scanning data of the lidar, enabling it to detect potential dangers and obstacles in complex terrain in a timely manner and react in advance. This effectively improves the chassis's autonomous navigation capability and adaptability, ensuring that the chassis can operate stably and safely in various complex environments.

[0041] Example 4

[0042] like Figures 1 to 6The diagram shows a general-purpose chassis suitable for complex terrain. A battery module 20 is slidably mounted on the rear side of the outer shell 2 to provide power to the chassis. At the same time, two charging contacts 21 are provided on the rear side of the battery module 20 for the chassis to charge the battery module 20. Circular grooves 22 are opened on both sides of the electrodes on the rear side of the battery module 20. A carrying member 23 is rotatably mounted in the circular grooves 22, so that the user can easily pull out the battery module 20 through the carrying member 23 for easy replacement.

[0043] Furthermore, to cope with unexpected situations in complex road conditions, a triangular connector 24 is specially designed on the rear side of the battery module 20. Users can use this connector 24 to power or urgently charge other devices, such as providing power to mobile phones, walkie-talkies, and other devices during field operations, greatly improving the chassis's emergency support capabilities. In addition, a protective plug 25 is provided on the outside of the triangular connector 24. When the triangular connector 24 is not in use, the protective plug 25 can effectively prevent liquids, moisture, or debris from entering the connector, protecting it from damage and ensuring that it can work normally when needed, thus improving the chassis's reliability and durability.
