Description

Technical Field

[0001] The present application belongs to the technical field of track-guided vehicle systems, and in particular, relates to a limit structure, a track-guided vehicle system and a shuttle bus. Background Art

[0002] When a rail-guided vehicle runs on a track and stops at a desired position, due to external factors, the rail-guided vehicle will slide on the track and leave the desired stop position. In order to solve this problem, it is usually necessary to set a limit structure to accurately limit the rail-guided vehicle at the desired position. However, the existing limit structure is complex, and a large activity space is usually required during the limit process of the rail-guided vehicle, which will result in a large installation space requirement for the limit structure. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a limiting structure, a track-guided vehicle system and a shuttle vehicle, which are intended to accurately limit the vehicle at a desired position, while having a compact structure and reducing the space required for movement and installation.

The drive assembly can accurately make the limiting part move between the first position and the second position without manual intervention, thereby greatly improving the convenience and efficiency of operation. The design of the limiting part allows it to slide between the two positions, thereby accurately controlling the movement of the vehicle. When the limiting part is in the first position, it effectively limits the movement of the vehicle and ensures that the vehicle stops at a predetermined position; and when the limiting part is in the second position, it releases the restriction on the movement of the vehicle and allows the vehicle to travel freely. This precise control is essential to ensure the safety and stability of the vehicle. By limiting the movement of the vehicle, the limiting structure can not only accurately limit the vehicle at the desired position to prevent the vehicle from accidentally sliding or leaving the track, thereby improving the safety of the track-guided vehicle system. At the same time, the stability and reliability of the drive assembly ensure that the limiting part can work effectively for a long time and reduce the frequency of failures and repairs. The design of the sliding-mounted limiting part is usually relatively simple and easy to maintain and adjust. If the limiting part needs to be replaced or repaired, it can be easily disassembled and reinstalled. In addition, it is relatively easy to adjust the position of the limiting part as needed. Since the stopper slides on the mounting base, no additional space is required to install or operate it. This compact design helps save space.

[0030] According to the shuttle bus of the present application, by directly connecting the mounting seat to the track, it is possible to ensure that the limiting structure is firmly fixed on the track. This connection method provides strong support and stability, so that the vehicle is not easily affected by external factors such as vibration, impact, etc. during driving, thereby ensuring the smooth operation of the vehicle.

[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] Reference below Figure 1-Figure 6 The limiting structure, the track-guided vehicle system and the shuttle bus according to the embodiments of the present application are described.

[0048] Reference Figure 1, Figure 2 , Figure 3 as well as Figure 5 The limiting structure 100 is applicable to a track-guided vehicle system 1000 , wherein the track-guided vehicle system 1000 includes a track 200 and a vehicle adapted to move on the track 200 . The limiting structure 100 includes a mounting seat 110 , a limiting portion 120 and a driving assembly 130 .

[0049] The mounting seat 110 is used to be mounted on the track 200 .

[0050] It should be noted that there are many ways to install the mounting seat 110 on the track 200. For example, in one embodiment, a bolt hole can be provided on the mounting seat 110, and the mounting seat 110 can be fixed to the track 200 by bolts. In another embodiment, the mounting seat 110 and the track 200 can also be fixed together by welding. In other embodiments, the mounting seat 110 can also be installed on a specific part of the track 200 by a snap-fit ​​structure or gluing, etc. Specifically, this application does not limit this.

[0051] The limiting part 120 is slidably mounted on the mounting seat 110 between a first position and a second position. When the limiting part 120 is in the first position, the limiting part 120 is suitable for limiting the movement of the vehicle. When the limiting part 120 is in the second position, the limiting part 120 is suitable for releasing the restriction on the movement of the vehicle. In this way, this design allows the limiting part 120 to quickly switch between restriction and release according to actual needs. When the vehicle needs to be fixed or kept in a specific position, the limiting part 120 can slide to the first position to limit its movement; when the vehicle needs to move freely, the limiting part 120 can slide to the second position to release the restriction. This flexibility improves the convenience of vehicle use. By limiting the movement of the vehicle, the limiting part 120 can ensure the safety of the vehicle in certain circumstances. For example, during maintenance, inspection or loading / unloading, limiting the movement of the vehicle can prevent accidents and protect the safety of the staff and the vehicle itself. During the sliding installation process of the limiting part 120, precise position control can be achieved. This means that the limiter 120 can accurately limit the movement of the vehicle within a specific range, or completely remove the restriction to allow the vehicle to move freely. This precise control helps to improve the accuracy and reliability of vehicle operation. The design of the sliding-mounted limiter 120 is usually relatively simple, which is convenient for maintenance and adjustment. If the limiter 120 needs to be replaced or repaired, it can be easily disassembled and reinstalled. In addition, it is relatively easy to adjust the position of the limiter 120 as needed. Since the limiter 120 slides on the mounting seat 110, no additional space is required to install or operate it. This compact design helps to save space, especially in environments with limited space.

[0052] The drive assembly 130 is mounted on the mounting seat 110, and the drive assembly 130 is used to drive the limit portion 120 to move. In this way, through the intervention of the drive assembly 130, the movement of the limit portion 120 can be automated and intelligent. This eliminates the need for manual operation, reduces the possibility of human error, and improves the response speed and accuracy of the overall system. The drive assembly 130 can enable the limit portion 120 to accurately switch between the first position and the second position, thereby achieving precise restriction and release of vehicle movement. Automated drive can significantly improve operational efficiency. Whether it is to quickly limit vehicle movement or quickly release restrictions, the drive assembly 130 can respond quickly, reducing waiting time and operation time, and improving work efficiency.

[0053] According to the limiting structure 100 of the present application, by setting the driving assembly 130, the limiting structure 100 can realize automatic and intelligent operation. The driving assembly 130 can accurately make the limiting part 120 move between the first position and the second position without manual intervention, thereby greatly improving the convenience and efficiency of operation. The design of the limiting part 120 allows it to slide between the two positions, thereby accurately controlling the movement of the vehicle. When the limiting part 120 is in the first position, it effectively limits the movement of the vehicle and ensures that the vehicle stops at the predetermined position; and when the limiting part 120 is in the second position, it removes the restriction on the movement of the vehicle and allows the vehicle to travel freely. This precise control is essential to ensure the safety and stability of the vehicle. By limiting the movement of the vehicle, the limiting structure 100 can not only accurately limit the vehicle at the desired position to prevent the vehicle from accidentally sliding or derailing, thereby improving the safety of the track-guided vehicle system 1000. At the same time, the stability and reliability of the driving assembly 130 ensure that the limiting part 120 can work effectively for a long time, reducing the frequency of failures and repairs. The design of the slidingly mounted limiter 120 is usually relatively simple, and is easy to maintain and adjust. If the limiter 120 needs to be replaced or repaired, it can be easily removed and reinstalled. In addition, it is relatively easy to adjust the position of the limiter 120 as needed. Since the limiter 120 slides on the mounting seat 110, no additional space is required to install or operate it. This compact design helps save space.

[0054] Refer to 4 and Figure 6In one embodiment, the vehicle has a first abutting surface 311 and a second abutting surface 312 that are arranged oppositely and spaced apart along its moving direction, and the limiting portion 120 includes a first limiting block 121 and a second limiting block 122 that are arranged oppositely and spaced apart along the moving direction of the vehicle. When the limiting portion 120 is in the first position, the first limiting block 121 is suitable for abutting against the first abutting surface 311, and the second limiting block 122 is suitable for abutting against the second abutting surface 312. In this way, since the first limiting block 121 and the second limiting block 122 abut against the first abutting surface 311 and the second abutting surface 312 of the vehicle respectively, this double abutting design provides stronger stability and reliability, ensuring that the vehicle is effectively restricted in a fixed position to prevent it from moving accidentally. By setting two limiting blocks, the force applied to the vehicle can be evenly distributed on the first abutting surface 311 and the second abutting surface 312, avoiding the problem of instability or damage caused by single-point force. This uniform force distribution also helps to extend the service life of the vehicle and the limiting structure 100. By ensuring that the first limit block 121 and the second limit block 122 are in close contact with the corresponding first abutment surface 311 and the second abutment surface 312, this design can prevent the vehicle from slipping or tipping over when subjected to external force, thereby improving the safety of the entire track-guided vehicle system 1000. Since the design of the limit portion 120 is relatively simple and clear, the operator can intuitively understand its mode of action, thereby simplifying the operation process. At the same time, the contact relationship between the limit block and the abutment surface also facilitates daily maintenance and inspection, reducing maintenance costs and difficulties.

[0055] Reference Figure 1 , Figure 4 as well as Figure 6In one embodiment, the limiting portion 120 further includes a connecting portion 123, the two ends of the connecting portion 123 are respectively connected to the first limiting block 121 and the second limiting block 122, the driving assembly 130 includes a linear driving portion 131, the linear driving portion 131 is suitable for horizontal movement, and the linear driving portion 131 is connected to the connecting portion 123, so that the first limiting block 121 and the second limiting block 122 are connected together through the connecting portion 123, and the linear driving portion 131 can ensure that the two limiting blocks move synchronously during driving. This synchronization and coordination is crucial for accurately controlling the movement of the vehicle, and prevents operational problems caused by inconsistent movement of the limiting blocks. Since the linear driving portion 131 is directly connected to the connecting portion 123, the entire driving process is more direct and simple. This reduces the complexity of the driving structure, reduces potential failure points, and improves the stability and reliability of the limiting structure 100. The linear drive part 131 can move in the horizontal direction. This transmission mode enables the force to act directly on the connecting part 123, thereby efficiently transmitting to the first limit block 121 and the second limit block 122. This helps to reduce energy loss and improve drive efficiency. Since the connection between the drive assembly 130 and the limit part 120 is relatively simple and clear, the installation and maintenance process becomes more convenient. This reduces the difficulty and cost of operation and improves the maintainability of the system.

[0056] It should be noted that there are many types of the linear drive mechanism. For example, the linear drive mechanism may include a linear motor, an electric push rod, a hydraulic cylinder, a pneumatic cylinder, a rolling resistance screw, etc. Specifically, the present application does not limit the type of the linear drive mechanism.

[0057] Reference Figure 1 , Figure 4 as well as Figure 6 In one embodiment, the linear drive portion 131 is provided with a through hole along the spacing direction of the first limit block 121 and the second limit block 122, one end of the connecting portion 123 is connected to the first limit block 121, and the other end of the connecting portion 123 is suitable for passing through the through hole to be detachably connected to the second limit block 122. In this way, the design of the through hole enables the connecting portion 123 to directly pass through the driving portion and connect with the second limit block 122, which reduces additional connecting parts and fixing structures, making the entire limit structure 100 more compact and simplified. This simplification not only reduces the manufacturing cost, but also facilitates installation and maintenance. Since the connecting portion 123 is detachably connected to the second limit block 122, it makes the installation and disassembly process more flexible and convenient. When the limit block needs to be repaired or replaced, the connecting portion 123 can be easily disassembled without disassembling the entire drive assembly 130. This improves work efficiency and reduces maintenance costs.

[0058] It should be noted that there are many ways to achieve the detachable connection between the other end of the connecting portion 123 and the second limiting block 122. For example, in one embodiment, one end of the connecting portion 123 can be designed as a structure with an external thread, and a corresponding internal thread hole is provided on the second limiting block 122. By rotating the connecting portion 123, its external thread is tightly matched with the internal thread of the second limiting block 122, so as to achieve detachable connection. This connection method is simple and reliable. In another embodiment, the connecting portion 123 and the second limiting block 122 can be designed as a component with a buckle structure. Through the locking and unlocking mechanism of the buckle, the detachable connection between the connecting portion 123 and the second limiting block 122 can be easily achieved. This connection method is easy to operate and is suitable for the needs of quick installation and disassembly. In other embodiments, one end of the connecting portion 123 can be designed with a pin hole, and the second limiting block 122 is provided with a matching pin shaft hole. By inserting the pin shaft, the connecting portion 123 and the second limiting block 122 are fixed together. When disassembly is required, just pull out the pin shaft. This connection method has a simple structure. In addition, the present application does not limit the manner in which the other end of the connecting portion 123 is detachably connected to the second limiting block 122 .

[0059] Of course, in other embodiments, the connecting portion 123, the first limiting block 121, and the second limiting block 122 can also be integrally formed. In addition, the connecting portion 123 can be connected to the linear drive portion 131 by welding, threaded structure, etc., and specifically, this application does not limit this.

[0060] In addition, there are many ways to connect one end of the connecting portion 123 to the first limit block 121. For example, one end of the connecting portion 123 and the first limit block 121 can be integrally formed. In other ways, one end of the connecting portion 123 and the first limit block 121 can also be connected by glue, a threaded structure, a snap structure or a pin structure. Specifically, the present application does not limit this.

[0061] Reference Figure 1 , Figure 4 as well as Figure 6In one embodiment, the mounting seat 110 is further provided with a support portion, the support portion is located below the first limiting block 121 and the second limiting block 122, the support portion has a sliding plate 141 extending in the horizontal direction, the sliding plate 141 is suitable for slidingly abutting with the first limiting block 121 and the second limiting block 122, and the support portion serves as a support structure below the limiting block, and provides stable guidance and support for the limiting block through the sliding abutment between its sliding plate 141 and the limiting block. This design can ensure that the limiting block remains stable during the movement, and is not prone to shaking or offset, thereby improving the stability of the entire limiting structure 100. The sliding plate 141 is usually designed to be a smooth and wear-resistant material, which enables the limiting block to reduce friction with the mounting seat 110 during the sliding process and reduce wear. This helps to extend the service life of the limiting structure 100 and the mounting seat 110 and reduce the frequency of maintenance and replacement. The design of the support portion enables the limiting block to move accurately along a predetermined path during the sliding process. The guiding effect of the sliding plate 141 can ensure that the movement trajectory of the limit block is accurate and avoid deviation from the predetermined position, thereby improving the accuracy and reliability of the movement of the limit block. By introducing the support part, the design and manufacturing process of the limit structure 100 can be simplified. The existence of the support part makes the connection and cooperation between the limit block and the mounting seat 110 more direct and simple, reducing the manufacturing difficulty and cost. The design of the support part makes the movement of the limit block smoother and more flexible, and also improves the convenience and efficiency of operation.

[0062] Reference Figure 1 , Figure 4 as well as Figure 6In one embodiment, the sliding plate 141 includes a first sliding sub-plate 1411 and a second sliding sub-plate 1412 arranged in a spaced relationship along the spacing direction of the first limiting block 121 and the second limiting block 122, the first sliding sub-plate 1411 is suitable for slidingly abutting against the first limiting block 121, the second sliding sub-plate 1412 is suitable for slidingly abutting against the second limiting block 122, and the driving assembly 130 is located between the first sliding sub-plate 1411 and the second sliding sub-plate 1412. In this way, by dividing the sliding plate 141 into the first sliding sub-plate 1411 and the second sliding sub-plate 1412, and slidingly abutting against the corresponding first limiting block 121 and the second limiting block 122, this design can improve the stability of the entire limiting structure 100. The sliding abutment between the first sliding sub-plate 1411 and the first limiting block 121, and the sliding abutment between the second sliding sub-plate 1412 and the second limiting block 122, provide precise guidance for the movement of the first limiting block 121 and the second limiting block 122. This design enables the first limit block 121 and the second limit block 122 to slide along a predetermined trajectory, ensuring the accuracy and reliability of the movement. Placing the drive assembly 130 between the first sliding sub-plate 1411 and the second sliding sub-plate 1412 not only makes full use of the space, making the entire limit structure 100 more compact, but also helps to reduce the weight of the sliding plate 141. Since the designs of the first sliding sub-plate 1411, the second sliding sub-plate 1412, the first limit block 121 and the second limit block 122 are relatively independent, when any of the components is damaged or needs to be replaced, they can be operated separately, thereby simplifying the maintenance and replacement process and reducing maintenance costs and time. In addition, the sliding abutment design reduces single-point wear by dispersing the force, thereby improving the durability of the entire limit structure 100. At the same time, this design also helps to reduce the heat and noise generated by friction, and improves the reliability of the limit structure 100.

[0063] Reference Figure 1 , Figure 4 as well as Figure 6In one embodiment, the support portion includes a first support arm 142 and a second support arm 143 which are spaced apart along the spacing direction of the first limit block 121 and the second limit block 122. The lower end of the first support arm 142 and the lower end of the first support arm 143 are both connected to the mounting seat 110. The upper end of the first support arm 142 is bent away from the second support arm 143 to form the first sliding split plate 1411. The upper end of the second support arm 143 is bent away from the first support arm 142 to form the second sliding split plate 1412. In this way, the lower ends of the first support arm 142 and the second support arm 143 are both connected to the mounting seat 110 to form a stable support structure. This design enables the entire support portion to remain stable when subjected to external forces, reducing the risk of deformation or damage caused by vibration or impact. By spacing the first support arm 142 and the second support arm 143, the support portion can distribute the force received to a larger area, thereby reducing the pressure per unit area and improving the bearing capacity of the structure. The upper ends of the support arms are bent in directions away from each other to form a first sliding sub-plate 1411 and a second sliding sub-plate 1412. This design not only integrates the first sliding sub-plate 1411 with the first support arm 142, and the second sliding sub-plate 1412 with the second support arm 143, thereby reducing the number of components, but also optimizes the spatial layout, making the entire limiting structure 100 more compact.

[0064] Reference Figure 1 , Figure 4 as well as Figure 6 In one embodiment, the lower end of the first support arm 142 is connected to the lower end of the first support arm 143 through a mounting plate 144, and the mounting plate 144 is connected to the mounting seat 110. In this way, the lower end of the first support arm 142 is connected to the lower end of the second support arm 143 through the mounting plate 144, and then the mounting plate 144 is connected to the mounting seat 110. This design makes the assembly process simpler and more efficient. The assembler can quickly locate each component and assemble it quickly, thereby improving the assembly efficiency. The support arm and the mounting seat 110 are connected together through the mounting plate 144, which increases the contact area, ensures the stability and reliability of the entire support structure, and reduces the failure caused by loose connection or breakage. In addition, the mounting plate 144, as a bridge connecting the support arm and the mounting seat 110, can effectively disperse and transmit the force, so that the entire support can remain stable when subjected to external force. This design helps to reduce the deformation or damage of the support part caused by uneven or concentrated force.

[0065] Reference Figure 1The mounting seat 110 is provided with a strip hole 111 extending along the spacing direction of the first limiting block 121 and the second limiting block 122. The strip hole 111 is used for inserting a screw connector. The threaded end of the screw connector is used to connect with the track 200. The design of the strip hole 111 allows the screw connector to have a certain range of movement on the mounting seat 110. This design makes the connection between the mounting seat 110 and the track 200 no longer fixed at one point, but can be fine-tuned within the length range of the strip hole 111. This fine-tuning function is very useful for ensuring the accuracy and adaptability of the installation. The combination of the strip hole 111 and the screw connector makes the installation process more convenient. The installer can insert the screw connector into a suitable position in the strip hole 111 according to actual needs, and then rotate the screw connector to make it tightly connected with the track 200. This design reduces the complexity and time cost during installation. Since the screw connector can move in the strip hole 111, this design enables the mounting seat 110 to adapt to different installation environments and conditions. Whether it is facing slight size differences or the need to fine-tune the installation position, this design provides sufficient flexibility to ensure smooth installation. Although the strip hole 111 provides adjustment space, the tight connection of the screw connector ensures the structural stability between the mounting base 110 and the track 200. The firm connection between the threaded end of the screw connector and the track 200 can effectively resist external forces and vibrations, ensuring the durability and reliability of the installation.

[0066] Reference Figure 2 , Figure 3 as well as Figure 5 In a second aspect, the present application further provides a track-guided vehicle system 1000, the track-guided vehicle system 1000 comprising a track 200, a vehicle 300 and a limiting structure 100 as described above, the vehicle 300 being suitable for moving on the track 200, the mounting seat 110 being connected to the track 200, such as the limiting structure 100 as described above.

[0067] According to the track guided vehicle system 1000 of the present application, by directly connecting the mounting seat 110 to the track 200, it is possible to ensure that the limiting structure 100 is firmly fixed on the track 200. This connection method provides strong support and stability, so that the vehicle 300 is not easily affected by external factors such as vibration, impact, etc. during driving, thereby ensuring the smooth operation of the vehicle 300. The connection between the mounting seat 110 and the track 200 can ensure the accurate positioning of the limiting structure 100 on the track 200. This is essential for ensuring that the vehicle 300 moves according to the predetermined path and position. Accurate positioning helps to avoid the vehicle 300 from deviating from the track 200 or colliding with other vehicles 300, thereby improving the safety and reliability of the track guided vehicle system 1000. By directly connecting the mounting seat 110 to the track 200, the installation process of the limiting structure 100 can be simplified. This design reduces additional connectors and fixtures, making the track guided vehicle system 1000 more compact and efficient. The connection mode between the mounting seat 110 and the track 200 can be adjusted and optimized according to different needs and scenarios. For example, mounting seats 110 of different shapes and sizes can be designed to adapt to tracks 200 of different types and specifications. This flexibility enables the track-guided vehicle system 1000 to adapt to various complex and changeable application environments. In addition, by setting the drive assembly 130, the limiting structure 100 can achieve automated and intelligent operation. The drive assembly 130 can accurately enable the limiting portion 120 to move between the first position and the second position without manual intervention, thereby greatly improving the convenience and efficiency of operation. The design of the limiting portion 120 allows it to slide between the two positions, thereby accurately controlling the movement of the vehicle 300. When the limiting portion 120 is in the first position, it effectively limits the movement of the vehicle 300 and ensures that the vehicle 300 stops at a predetermined position; and when the limiting portion 120 is in the first position, it removes the restriction on the movement of the vehicle 300 and allows the vehicle 300 to travel freely. This precise control is essential to ensure the safety and stability of the vehicle 300. By limiting the movement of the vehicle 300, the limiting structure 100 can not only accurately limit the vehicle 300 at the desired position to prevent the vehicle 300 from accidentally sliding or getting off the track, thereby improving the safety of the track-guided vehicle system 1000. At the same time, the stability and reliability of the drive assembly 130 ensure that the limiting portion 120 can work effectively for a long time, reducing the frequency of failures and repairs. The design of the sliding-mounted limiting portion 120 is usually relatively simple, which is convenient for maintenance and adjustment. If the limiting portion 120 needs to be replaced or repaired, it can be easily disassembled and reinstalled. In addition, it is relatively easy to adjust the position of the limiting portion 120 as needed. Since the limiting portion 120 slides on the mounting seat 110, no additional space is required to install or operate it. This compact design helps to save space.

[0068] Reference Figures 2 to 6 In one embodiment, the mounting seat 110 is connected to the lower side of the track 200, so that the positioning of the entire limiting structure 100 in the horizontal direction is more accurate. This design helps to reduce the positioning error caused by loose connection or gap, and improves the positioning accuracy and reliability of the limiting structure 100. The mounting seat 110 is directly connected to the lower side of the track 200, reducing additional connectors and installation steps, thereby simplifying the entire installation process. This not only reduces the installation cost, but also improves the installation efficiency. Since the mounting seat 110 is directly connected to the lower side of the track 200, there is no need to set up additional support structures on both sides or above the track 200, thereby optimizing the spatial layout. This design helps to reduce the overall size of the equipment and improve space utilization. The direct connection between the mounting seat 110 and the lower side of the track 200 helps to disperse and transmit the force, and improves the strength of the entire limiting structure 100. In addition, the aesthetics of the track-guided vehicle system 300 is improved.

[0069] It should be noted that, in other embodiments, the mounting seat 110 may also be connected to the left or right side surface of the track 200. Specifically, the present application does not limit this.

[0070] Reference Figure 2 , Figure 3 as well as Figure 5 In one embodiment, the vehicle 300 includes a frame 310 and a plurality of wheels 320 mounted on the frame 310, at least part of the plurality of wheels 320 and / or the frame 310 are formed with a first abutting surface 311 and a second abutting surface 312, the limiting portion 120 includes a first limiting block 121 and a second limiting block 122 which are arranged opposite to and spaced apart in the moving direction of the vehicle 300, when the limiting portion 120 is in the first position, the first limiting block 121 is suitable for abutting against the first abutting surface 311, and the second limiting block 122 is suitable for abutting against the second abutting surface 312, thus, through the abutting design of the first limiting block 121 and the first abutting surface 311, and the second limiting block 122 and the second abutting surface 312, the vehicle 300 is effectively restricted in a predetermined position to prevent it from accidentally moving or sliding. This double abutment structure provides stronger stability, especially when the vehicle 300 is stationary or needs to be precisely positioned, it can ensure that the vehicle 300 stays stably at the specified position, thereby improving overall safety. The abutment relationship between the limit block and the abutment surface is intuitive and clear, and the operator can easily determine whether the limit structure 100 is in normal working condition. At the same time, due to the simple and clear structure, maintenance and inspection also become more convenient, reducing maintenance costs and difficulties. In addition, the first limit block 121 and the second limit block 122 are used to limit the movement of the vehicle 300 without causing damage to the wheel 320 or the frame.

[0071] It should be noted that, in one embodiment, at least part of the multiple wheels 320 may be formed with the first abutting surface 311 and the second abutting surface 312. In another embodiment, the frame 310 may be formed with the first abutting surface 311 and the second abutting surface 312. In other embodiments, at least part of the multiple wheels 320 and the frame 310 may be formed with the first abutting surface 311 and the second abutting surface 312. When at least part of the multiple wheels 320 and the frame 310 are formed with the first abutting surface 311 and the second abutting surface 312, the limiting effect is the best.

[0072] Reference Figure 5 and Figure 6 The frame 310 includes a frame body 311 and a contact block 312 protruding from the side of the frame body 311, the contact block 312 is formed with the first contact surface 311 and the second contact surface 312, and the wheel 320 is installed on the frame body 311. In this way, the design of the contact block 312 enhances the overall structural stability of the frame 310. The protruding contact block 312 abuts against the first limit block 121 and the second limit block 122 of the limit part 120. This design reduces the risk of deformation or damage of the frame 310 caused by vibration or impact. By installing the wheel 320 on the frame body 311, the stability and safety of the wheel 320 during driving are ensured. At the same time, the contact between the contact block 312 and the limit part 120 further enhances the stability of the vehicle 300 in an emergency, reduces the risk of rollover or loss of control, and improves safety. This design of the frame 310 makes the installation of the wheel 320 simpler and more intuitive. The operator can conveniently install the wheel 320 on the frame 311, thereby improving work efficiency. At the same time, due to the clear structure, maintenance and overhaul also become more convenient, thereby reducing maintenance costs.

[0073] Reference Figure 2 , Figure 3 as well as Figure 5In one embodiment, the first abutting surface 311 and the second abutting surface 312 together constitute a matching unit, and the matching units are provided in plurality. The first limiting block 121 and the second limiting block 122 together constitute a limiting unit, and the limiting units are provided in plurality. The limiting units and the matching units are provided in one-to-one correspondence. The matching units and the limiting units are provided in one-to-one correspondence, providing multi-point support and limiting for the vehicle 300. This design greatly enhances the stability of the vehicle 300 when driving, braking or turning, and reduces the shaking or deviation caused by external forces. At the same time, the multi-point limiting also improves the safety of the vehicle 300 and prevents safety accidents caused by the failure of a single limiting. By providing a plurality of matching units and limiting units and making them correspond one-to-one, high-precision control of the position of the vehicle 300 can be achieved. Each limiting unit can cooperate closely with the corresponding matching unit to ensure that the vehicle 300 stays accurately at the predetermined position. The weight and force of the vehicle 300 are shared by the multiple matching units and the limiting units, avoiding damage caused by excessive force at a single point. This design of dispersing the force helps to extend the service life of the frame 310 and the limiting structure 100 and reduce maintenance costs. Although multiple matching units and limiting units are designed, the installation process becomes relatively simple because the one-to-one correspondence between them is clear and intuitive. At the same time, during maintenance, the working status of each matching unit and limiting unit can be easily checked, and problems can be found and handled in time.

[0074] In a third aspect, the present application provides a shuttle bus for transporting a cleaning robot for a photovoltaic power station, wherein the shuttle bus includes the track-guided vehicle system as described above.

[0075] According to the shuttle bus of the present application, by directly connecting the mounting seat 110 to the track 200, it is possible to ensure that the limiting structure 100 is firmly fixed on the track 200.
