[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] Reference below Figures 1-8 A vehicle 100 according to an embodiment of the present invention is described.

[0038] Combine Figures 1-8As shown, the vehicle 100 according to the present invention may mainly include: a frame 10, a battery, an air reservoir 40, and a connecting ring 50. Among them, the frame 10 is a basic component that supports the vehicle body and bears the load of the vehicle, and provides a mounting position for other components to ensure the stability and reliability of the vehicle 100.

[0039] Furthermore, the battery includes a battery assembly 20 and a fixing bracket 30. The battery assembly 20 is detachably mounted on the vehicle frame 10, and the fixing bracket 30 is detachably mounted below the battery assembly 20 and includes a fixing plate 301. Specifically, the battery assembly 20 is primarily responsible for storing electrical energy for use in the vehicle 100. By detachably mounting and fixing the battery assembly 20 in a suitable position on the vehicle frame 10, not only is the installation and removal of the battery assembly 20 facilitated, as well as subsequent maintenance and replacement of the battery assembly 20, but it also provides a certain degree of protection for the battery assembly 20 and balances the weight distribution of the entire vehicle. In addition, the fixing bracket 30 is detachably mounted below the battery assembly 20 and includes a fixing plate 301. This improves the flexibility of the fixing bracket 30, allowing the fixing bracket 30 to be replaced or adjusted according to the type of battery assembly 20. Furthermore, the fixing bracket 30 can connect and fix other components to the bottom of the battery assembly 20 through the fixing plate 301, ensuring the stability of the connection, thereby improving the stability and reliability of the vehicle 100 structure.

[0040] Furthermore, the gas cylinder 40 is arranged below the battery assembly 20 and is in contact with the fixing plate 301. In this way, the gas cylinder 40 can be connected and fixed below the battery assembly 20 through the fixing plate 301, which can reduce the installation gap between the gas cylinder 40 and the fixing bracket 30, improve the installation accuracy, and ensure the reliability of the installation of the gas cylinder 40.

[0041] The connecting ring 50 is disposed around the periphery of the gas cylinder 40 and the fixing plate 301, and the connecting ring 50 detachably connects and fixes the gas cylinder 40 and the fixing plate 301. Specifically, by surrounding the connecting ring 50 around the periphery of the gas cylinder 40 and the fixing plate 301, and disposing the fixing plate 301 between the connecting ring 50 and the gas cylinder 40, the gas cylinder 40 and the fixing plate 301 are detachably connected and fixed. This not only makes the connection between the gas cylinder 40 and the fixing bracket 30 simple and direct, but also makes the connection between the gas cylinder 40 and the fixing bracket 30 stable and reliable. In addition, it also facilitates the installation and removal of the gas cylinder 40 and the fixing bracket 30, not only facilitating the subsequent maintenance and replacement of the gas cylinder 40, but also allows the battery assembly 20 and the fixing bracket 30 to be replaced while maintaining the layout of the gas cylinder 40 unchanged.

[0042] Therefore, by detachably arranging the battery assembly 20 on the vehicle frame 10, detachably arranging the fixing bracket 30 under the battery assembly 20, and detachably connecting and fixing the air cylinder 40 to the fixing plate 301 of the fixing bracket 30 through the connecting ring 50, when the vehicle 100 is matched with different types of batteries, it is only necessary to replace the battery assembly 20 and the matching fixing bracket 30, without changing the arrangement of the air cylinder 40 and the brake line, thereby achieving the uniform arrangement of the air cylinder 40 under different battery types and the universality of the brake line.

[0043] In some embodiments of the present invention, the fixing plate 301 can be set as an arc-shaped plate according to the size and structure of the air cylinder 40 to meet the fitting conditions between the fixing plate 301 and the air cylinder 40 .

[0044] Combine Figure 2 、 Figure 3 and Figure 6 As shown, the connecting ring 50 includes a ring body 5011 and a fastener 5012.

The two ends of the ring body 5011 are spaced apart, and the fastener 5012 removably connects and secures the two ends of the ring body 5011. Specifically, the fastener 5012 removably connects and secures the two ends of the ring body 5011. After the ring body 5011 is disposed around the outer periphery of the gas reservoir 40 and the fixed plate 301, the gas reservoir 40 and the fixed plate 301 are removably connected and secured. This facilitates installation and removal of the gas reservoir 40 and the fixed plate 301. In addition, the fastener 5012 can tighten the ring body 5011, thereby not only tightly connecting and securing the gas reservoir 40 and the fixed plate 301 but also ensuring the stability of the connection between the gas reservoir 40 and the fixed plate 301.

[0045] Combine Figure 2 、 Figure 3 and Figure 6 As shown, the ring body 5011 is provided with a first threaded hole and a second threaded hole at both ends, and the fastener 5012 is a bolt. The bolt is sequentially passed through the first threaded hole and the second threaded hole to detachably thread the two ends of the ring body 5011. Specifically, the ring body 5011 is provided with a first threaded hole and a second threaded hole at both ends. The first threaded hole and the second threaded hole have the same structure and size. The first bolt is sequentially passed through the first threaded hole and the second threaded hole, so that the two ends of the ring body 5011 are detachably threaded and fixed. This not only makes the connection between the two ends of the ring body 5011 simple, direct, stable and reliable, but also facilitates the installation and removal of the ring body 5011, thereby facilitating the installation and removal of the air reservoir 40 and the fixing plate 301, and can improve the flexibility and reliability of the vehicle 100 structure.

[0046] In some embodiments of the present invention, the fastener 5012 can also be set as a fastener that cooperates with a tensioning pin, a tightening pin and a hexagonal stud. This not only ensures the stability and reliability of the connection between the fixed bracket 30 and the air cylinder 40, but also can adjust the tensioning degree of the connecting ring 50, improve the flexibility of the connecting ring 50, and enable the connecting ring 50 to be appropriately adjusted according to the outer circumference size of the air cylinder 40.

[0047] Combine Figure 3 、 Figure 6 and Figure 8 As shown, the fixing plate 301 includes a first fixing plate 3011 and a second fixing plate 3012, the air cylinder 40 includes a front axle air cylinder 401 and a rear axle air cylinder 402, the front axle air cylinder 401 and the first fixing plate 3011 are in contact with each other, and the rear axle air cylinder 402 and the second fixing plate 3012 are in contact with each other, the connecting ring 50 includes a first connecting ring 501 and a second connecting ring 502, the first connecting ring 501 is arranged around the outer periphery of the first fixing plate 3011 and the front axle air cylinder 401, and the first connecting ring 501 detachably connects and fixes the first fixing plate 3011 and the front axle air cylinder 401, the second connecting ring 502 is arranged around the outer periphery of the second fixing plate 3012 and the rear axle air cylinder 402, and the second connecting ring 502 detachably connects and fixes the second fixing plate 3012 and the rear axle air cylinder 402.

[0048] Specifically, the fixing plate 301 includes a first fixing plate 3011 and a second fixing plate 3012, and the air cylinder 40 includes a front axle air cylinder 401 and a rear axle air cylinder 402. The front axle air cylinder 401 and the first fixing plate 3011 are in contact with each other, and the rear axle air cylinder 402 and the second fixing plate 3012 are in contact with each other. In this way, the front axle air cylinder 401 and the rear axle air cylinder 402 can be connected and fixed under the battery assembly 20 through the first fixing plate 3011 and the second fixing plate 3012, which can reduce the installation gap between the air cylinder 40 and the fixed bracket 30 and improve the installation accuracy.

[0049] Furthermore, the connecting ring 50 includes a first connecting ring 501 and a second connecting ring 502. The first connecting ring 501 is arranged around the outer periphery of the front axle air reservoir 401 and the first fixing plate 3011, and the first fixing plate 3011 is arranged between the first connecting ring 501 and the front axle air reservoir 401, so that the front axle air reservoir 401 and the first fixing plate 3011 are detachably connected and fixed by the first connecting ring 501. The second connecting ring 502 is arranged around the outer periphery of the rear axle air reservoir 402 and the second fixing plate 3012, and the second fixing plate 3012 is arranged on the second connecting ring 502. and the rear axle air cylinder 402, so that the rear axle air cylinder 402 and the second fixing plate 3012 are detachably connected and fixed through the second connecting ring 502, which not only makes the connection between the air cylinder 40 and the fixing bracket 30 simple and direct, but also makes the connection between the air cylinder 40 and the fixing bracket 30 stable and reliable. In addition, it also facilitates the installation and disassembly between the air cylinder 40 and the fixing bracket 30, which not only facilitates the subsequent maintenance and replacement of the air cylinder 40, but also allows the battery assembly 20 and the fixing bracket 30 to be replaced while maintaining the layout of the air cylinder 40 unchanged.

[0050] Combine Figure 3 、 Figure 4 and Figure 5 As shown, the battery is a first-type battery 201, which includes a first battery assembly and a first fixing bracket 305. There are two first fixing brackets 305, spaced apart in the left-right direction. Each first fixing bracket 305 is provided with a first fixing plate 3011 and a second fixing plate 3012. The first fixing plate 3011 and the second fixing plate 3012 extend in the left-right direction, and the distance between the first fixing plate 3011 and the second fixing plate 3012 is set evenly in the left-right direction. This arrangement not only allows the front axle gas reservoir 401 and the rear axle gas reservoir 402 to be positioned below the first-type battery 201 via the first fixing plates 3011 and the second fixing plates 3012, but also ensures the stability and reliability of the connection between the first fixing bracket 305 and the gas reservoir 40.

[0051] Combine Figure 3 、 Figure 4 and Figure 5As shown, the two first fixed brackets 305 each include a first main body plate 3051 and a first connecting plate 3052, the first main body plate 3051 is extended in the up and down directions, the first connecting plate 3052 is arranged at the upper end of the first main body plate 3051 and is bent relative to the first main body plate 3051, and the first connecting plate 3052 is extended toward one side of the front and back directions, the first fixed plate 3011 is arranged at the lower end of the first main body plate 3051 of one of the two first fixed brackets 305 and is bent relative to the first main body plate 3051, and the first fixed plate 3011 is extended on the other side of the front and back directions, the second fixed plate 3012 is arranged at the lower end of the first main body plate 3051 of the other of the two first fixed brackets 305 and is bent relative to the first main body plate 3051, and the second fixed plate 3012 is extended toward the other side of the front and back directions.

[0052] Furthermore, the first connecting plate 3052 is suitable for connecting to the first battery assembly, and the first fixing plate 3011 and the second fixing plate 3012 of the two first fixing brackets 305 are respectively suitable for connecting to the front axle gas cylinder 401 and the rear axle gas cylinder 402. Such an arrangement can not only ensure the structural strength of the two first fixing brackets 305, but also simplify the connection structure between the first fixing bracket 305 and the first battery assembly and the gas cylinder 40, reduce the installation difficulty between the first battery assembly, the first fixing bracket 305 and the gas cylinder 40, and further ensure the rationality and reliability of the structural arrangement.

[0053] Combine Figure 6 、 Figure 7 and Figure 8 As shown, the battery is a second-type battery 202, which includes a second battery assembly and a second fixing bracket 306. The second fixing bracket 306 is provided with a first fixing plate 3011 and a second fixing plate 3012. The first fixing plate 3011 and the second fixing plate 3012 are both arc-shaped and spaced apart in the left-right direction. The distance between the first fixing plate 3011 and the second fixing plate 3012 increases gradually from bottom to top. This arrangement not only allows the front axle gas reservoir 401 and the rear axle gas reservoir 402 to be positioned below the second-type battery 202 via the first fixing plate 3011 and the second fixing plate 3012, but also allows the second fixing bracket 306 to better fit the gas reservoir 40, thereby reducing installation clearance and improving installation accuracy. Furthermore, while ensuring the stability of the first fixing plate 3011 and the second fixing plate 3012, the distance between the two mounting points of the first fixing plate 3011 and the second fixing plate 3012 can be reduced, making the internal structure of the vehicle 100 more compact.

[0054] Furthermore, the air cylinder 40 is cylindrical, and the first fixing plate 3011 and the second fixing plate 3012 of the second fixing bracket 306 are also arc-shaped, so that the air cylinder 40 can fit tightly with the first fixing plate 3011 and the second fixing plate 3012 of the second fixing bracket 306, which not only facilitates the installation and fixation of the air cylinder 40, but also improves the stability of the connection and fixation between the air cylinder 40 and the second fixing bracket 306, avoids safety hazards caused by loosening or falling off of the air cylinder 40, and improves the stability and reliability of the vehicle 100 structure.

[0055] Furthermore, the distance between the first fixing plate 3011 and the second fixing plate 3012 of the second fixing bracket 306 in the left-right direction gradually increases from bottom to top, so that the distance between the two installation points of the first fixing plate 3011 and the second fixing plate 3012 can be reduced, and the contact area between the fixing bracket 30 and the second battery assembly can be reduced, which can facilitate the vehicle 100 to improve or upgrade the second battery assembly.

[0056] Combine Figure 6 、 Figure 7 and Figure 8 As shown, the second fixed bracket 306 includes a second main body plate 3061 and a second connecting plate 3062, the second main body plate 3061 is extended in the up and down directions, the second connecting plate 3062 is arranged at the upper end of the second main body plate 3061 and is bent relative to the second main body plate 3061, and the second connecting plate 3062 is extended toward one side of the front and back directions, the first fixing plate 3011 and the second fixing plate 3012 are arranged at the lower end of the second main body plate 3061, the first fixing plate 3011 and the second fixing plate 3012 are bent relative to the second main body plate 3061, and the first fixing plate 3011 and the second fixing plate 3012 are extended toward the other side of the front and back directions.

[0057] Furthermore, the second connecting plate 3062 is suitable for connecting to the second battery assembly, and the first fixing plate 3011 and the second fixing plate 3012 of the second fixing bracket 306 are respectively suitable for connecting to the front axle gas cylinder 401 and the rear axle gas cylinder 402. Such an arrangement can not only ensure the structural strength of the second fixing bracket 306, but also simplify the connection structure between the second fixing bracket 306 and the second battery assembly and the gas cylinder 40, reduce the difficulty of installation between the second battery assembly, the second fixing bracket 306 and the gas cylinder 40, and further ensure the rationality and reliability of the structural arrangement.

[0058] Combine Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, the first fixing plate 3011 and the second fixing plate 3012 are both provided with a flanged stopper 307 at one end thereof, which is away from the first connecting plate 3052 in the front-to-back direction. The flanged stopper 307 extends upward, and the first connecting ring 501 and the flanged stopper 307 are engaged in a front-to-back positional relationship, while the second connecting ring 502 and the flanged stopper 307 are engaged in a front-to-back positional relationship. Specifically, by providing flanged stoppers on the sides of the first and second fixing plates 3011 and 3012, which are away from the main plate in the front-to-back direction, and by bending the flanged stoppers relative to the first and second fixing plates 3011 and 3012 and extending upward, the first and second connecting rings 501 and 502 can better engage with the flanged stoppers, thereby more stably connecting and fixing the gas cylinder 40 to the second fixing bracket 306, preventing the gas cylinder 40 from loosening or falling off, and further improving the stability and reliability of the vehicle 100 structure.

[0059] Combine Figure 1 、 Figure 3 and Figure 6 As shown, the battery assembly 20 includes a battery box and a battery component, the battery component is arranged in the battery box, a fifth through-hole 303 is provided on the fixing bracket 30, and a sixth through-hole is provided on the battery box. The fifth through-hole 303 corresponds to the sixth through-hole and is connected and fixed by a third fastener 304.

[0060] Specifically, by placing the battery in the battery box, the battery box can not only firmly support and fix the battery to prevent the battery from moving or falling off during the driving of the vehicle 100, but also protect the battery, avoid or reduce the physical impact on the battery, prevent water or other substances from damaging the internal structure of the battery, thereby affecting the normal working performance of the battery, and improve the stability and safety of the vehicle 100.

[0061] Furthermore, by setting a fifth perforation 303 on the fixing bracket 30 and a sixth perforation on the battery box, and the fifth perforation 303 corresponds to the sixth perforation in structure and position, the third fastener 304 is sequentially penetrated through the fifth perforation 303 and the sixth perforation, thereby connecting and fixing the fixing bracket 30 to the battery box. This not only makes the connection between the fixing bracket 30 and the battery box simple and direct, but also makes the connection between the fixing bracket 30 and the battery box firm and reliable. In addition, it also facilitates the installation and disassembly between the fixing bracket 30 and the battery box, and facilitates the subsequent maintenance and replacement of the battery box and the fixing bracket 30.

[0062] In some embodiments of the present invention, the fifth through-hole 303 and the sixth through-hole may be threaded holes, and the third fastener 304 may be a bolt.

This can not only further improve the stability and reliability of the connection and fixation between the fixing bracket 30 and the battery box, but also make the force at the connection between the fixing bracket 30 and the battery box more uniform, and avoid deformation or fracture of the connection between the fixing bracket 30 and the battery box due to stress concentration.

[0064] In some embodiments of the present invention, the first type battery 201 may be a lead-acid battery, and the second type battery 202 may be a lithium battery. Lead-acid batteries are generally larger than lithium batteries. Lead-acid batteries are characterized by low cost and high safety. Using lead-acid batteries as the first type battery 201 can reduce the manufacturing cost of the vehicle 100 and improve the safety of the vehicle 100. Lithium batteries are characterized by being lightweight, environmentally friendly, capable of storing large amounts of energy, and capable of fast charging. Using lithium batteries as the second type battery 202 can further reduce the weight of the vehicle 100, optimize the structural layout of the vehicle 100, and enhance the stability of the vehicle 100. Furthermore, when the volume of the first type battery 201 is larger than the volume of the second type battery 202, due to the setting of the first fixing bracket 305 and the second fixing bracket 306, when the battery type matching the vehicle 100 is replaced, the installation points of the front axle air cylinder 401 and the rear axle air cylinder 402 can be adjusted to achieve the unification of the layout scheme of the air cylinder 40 and the layout of the brake pipe. This not only improves the versatility of the structural layout of the vehicle 100, but also reduces the development cost of the entire vehicle.
