[0021] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] The present application provides a vehicle air storage cylinder and a vehicle to solve the problem in the related art that when drainage is required, the driver usually needs to enter under the vehicle to operate the drainage valve, which may easily cause personal hazards such as head bumps.

[0023] In a first aspect, the present application provides a vehicle air tank, such as Figures 1 to 3 As shown, the vehicle air storage cylinder includes a cylinder body 10 , a water outlet joint 20 , an L-shaped support pipe 30 , a soft drainage pipe 40 and a pull rope 50 .

[0024] Among them, the cylinder 10 has an air storage cavity, and the cylinder 10 can be in the shape of a cylinder or a rectangular parallelepiped, etc. The cylinder 10 is used to store compressed air; the water outlet joint 20 is arranged at the bottom of the cylinder 10 and is fixedly connected to the cylinder 10, the water outlet joint 20 extends vertically, and the lower end of the water outlet joint 20 has a water outlet 221 connected to the air storage cavity, the water outlet joint 20 is a water pipe joint, and the water outlet joint 20 can be welded to the bottom of the cylinder 10; the support pipe 30 includes a first part 31 extending vertically and a second part 32 extending horizontally, the first part 31 is sleeved on the water outlet joint 20, and is connected to the water outlet joint 20 around the axial rotation of the first part 31, the second part 32 is fixedly connected to the first part 31, and the support pipe 30 includes a first part 31 extending vertically and a second part 32 extending horizontally, the first part 31 is sleeved on the water outlet joint 20, and is connected to the water outlet joint 20 around the axial rotation of the first part 31, the second part 32 is fixedly connected to the first part 31, and the support pipe 30 includes a first part 31 extending vertically and a second part 32 extending horizontally. The first part 31 and the second part 32 both have interconnected wiring channels, and the second part 32 is provided with a first opening 321 at one end away from the first part 31, and the support tube 30 is used to provide support for the soft drain pipe 40; the first end of the drain pipe 40 is sleeved on the water outlet joint 20 and is located in the wiring channel, and the second end of the drain pipe 40 extends out of the wiring channel from the first opening 321, and the second end of the drain pipe 40 has a drain port 41 connected to the water outlet 221, and the second end of the drain pipe 40 is provided with a manual water valve 60 for opening and closing the drain port 41; the first end of the pull rope 50 is fixedly connected to the drain pipe 40, and the second end of the pull rope 50 is connected to the outer side of the vehicle body 81.

[0025] It is understandable that when the accumulated water in the cylinder 10 needs to be discharged, the driver can hold the second end of the pull rope 50 outside the vehicle body 81, and drive the support pipe 30 to rotate by pulling the pull rope 50. When the support pipe 30 rotates, it will drive the soft drain pipe 40 to twist. When the first opening 321 of the second part 32 of the support pipe 30 is turned toward or exposed outside the vehicle body 81, the driver can manually operate the manual water valve 60 outside the vehicle body 81, so that the drain port 41 is opened for drainage. The driver does not need to enter the bottom of the vehicle to operate the drain valve for drainage, which makes it more convenient to operate the drain valve for drainage and can prevent personal accidents such as head bumps. Among them, the manual water valve 60 can be a water valve of a push-type water valve or a rotating water valve, and the specific type of the water valve can be selected according to actual needs.

[0026] In one embodiment, the water outlet joint 20 includes a first head 21 and a second head 22, the first head 21 is arranged at the bottom of the cylinder 10 and is fixedly connected to the cylinder 10; the second head 22 is arranged at the bottom of the first head 21 and is fixedly connected to the first head 21, the pipe diameter of the second head 22 is smaller than the pipe diameter of the first head 21, and the second head 22 has the water outlet 221.

[0027] The first part 31 is sleeved on the first head 21 and connected to the first head 21 for rotation around the axial direction of the first part 31, and the first end of the drain pipe 40 is sleeved on the second head 22. It can be understood that the first head 21 and the second head 22 are both circular water pipes, the first head 21 and the second head 22 can be integrally formed, and the pipe diameter of the first head 21 is larger than the pipe diameter of the second head 22, so that the connection between the drain pipe 40 and the second head 22 is more convenient, and the outer side of the drain pipe 40 can be bound with a reinforcing member such as a screw or a pipe clamp to improve the connection strength between the drain pipe 40 and the second head 22.

[0028] In one embodiment, an annular groove 211 is provided on the outer peripheral side of the first head 21, and an annular protrusion 33 located in the annular groove 211 is provided on the inner wall of the first part 31. The first part 31 is rotatably connected to the first head 21 through the cooperation between the annular protrusion 33 and the annular groove 211. The annular protrusion 33 can rotate in the annular groove relative to the central axis of the first head 21, so that the first part 31 can rotate relative to the central axis of the first head 21, and the cooperation between the annular groove and the annular protrusion 33 can limit the first part 31 and prevent the first part 31 from separating from the first head 21.

[0029] In one embodiment, the vehicle air cylinder also includes a torsion spring 70, which is sleeved on the outer side of the first part 31, the first end of the torsion spring 70 is fixedly connected to the first part 31, the second end of the torsion spring 70 is fixedly connected to the first end of the torsion spring 70 and the first part 31, and the torsion spring 70 is used to reset the support tube 30. When the torsion spring 70 is in a natural telescopic state, the projection of the vehicle body 81 on the ground covers the projection of the support tube 30 and the drainage pipe 40 on the ground.

[0030] It should be noted that the torsion spring 70 is made of elastic materials such as elastic steel. The torsion spring 70 can provide a reset torque for the support tube 30. When the support tube 30 is driven to rotate by pulling the pull rope 50 so that the first opening 321 of the second part 32 of the support tube 30 is facing or exposed to the outside of the vehicle body 81, the torsion spring 70 is in a stretched state. When the drainage is completed, the restraint on the pull rope 50 is released, and the torsion spring 70 returns to a natural telescopic state. The support tube 30 rotates and resets under the torque of the torsion spring 70, so that the support tube 30 and the drain pipe 40 are hidden directly under the vehicle body 81, avoiding the safety hazard caused by the support tube 30 and the drain pipe 40 extending out of the vehicle body 81.

[0031] In one embodiment, the support pipe 30 is a hard support pipe 30 , and the support pipe 30 may be a steel water pipe, so that the support pipe 30 has sufficient strength to provide good support for the drainage pipe 40 .

[0032] In one embodiment, the drain pipe 40 is a retractable elastic drain pipe 40, so that when the vehicle air tank needs to be drained, the driver can stretch the drain pipe 40 to make the drain pipe 40 longer, so that the drain port 41 of the drain pipe 40 is farther away from the vehicle body 81, thereby avoiding personal accidents such as head collision when the vehicle air tank is drained; after the drainage is completed, the restraint on the drain pipe 40 is released, and the drain pipe 40 automatically shrinks to reduce the length of the drain pipe 40. The drain pipe 40 can be a rubber tube, an elastic metal tube or a tube made of other materials.

[0033] Furthermore, the projection of the manual water valve 60 on the second part 32 covers the first opening 321, that is, the outer contour of the manual water valve 60 is larger than the caliber of the first opening 321, so that when the drain pipe 40 contracts, the manual water valve 60 cannot enter the support tube 30 through the first opening 321, thereby preventing the drain pipe 40 from retracting into the support tube 30 under the action of elastic force.

[0034] In a second aspect, based on the above-mentioned vehicle air cylinder, the present application further provides a vehicle, the vehicle comprising a vehicle body 81 and a vehicle air cylinder as described in any one of the above-mentioned embodiments, the vehicle air cylinder being installed at the bottom of the vehicle body 81. The vehicle may be a loader, a transporter, a dump truck or other types of vehicles.

[0035] In one embodiment, a hook 82 is fixed on the outer side of the vehicle body 81, and the second end of the pull rope 50 is connected to the hook 82. The hook 82 can provide a good fixing point for the pull rope 50, making the placement of the pull rope 50 more convenient.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
