In some embodiments, the front support section 41 is configured as a constant-section beam. A beam that has the same cross-sectional dimensions everywhere along its length is a constant-section beam. Because the weight of the driver's cab 12 is relatively large, and the front support front section 41 corresponds to support the driver's cab 12, the front support front section 41 is set as a constant-section beam to improve the bending strength of the front support front section 41, so that the driver's cab 12 is assembled. The front section 41 is more stable in the front support. In one embodiment, the length of the front support section 41 is shorter than the length of the front support section 42 , and the cross section of the front support section 41 is substantially equal to the cross section of the front end of the front support section 42 .

In some embodiments, the front support rear section 42 includes a connected first subsection 43 and a second subsection 44, the first subsection 43 is connected to the rear end of the front support front section 41, and the second subsection 44 is connected to the lower The front end of the 26th section 8, the cross section of the first subsection 43 gradually increases from front to back. That is to say, the front supporting section 41 and the sinking section 8 are connected through the first subsection 43 and the second subsection 44 sequentially from front to back. Since the sinking section 8 is concave compared to other parts of the chassis girder 5, the connection positions at both ends of the sinking section 8 are prone to stress concentration. In order to reduce or avoid the stress concentration, the present application places the The first sub-section 43 is set as a variable cross-section beam to increase the ability of the front end of the sinking section 8 to bear lateral loads and vertical loads, and reduce the risk of deformation or breakage at the connection positions at both ends of the sinking section 8 . In addition, what is assembled at the first subsection 43 is a battery pack 6 with relatively high mass, and the cross section of the first subsection 43 is set to gradually increase from front to back, so that the thickness of the first subsection 43 gradually increases from front to back , so that the pressure that can be withstood gradually increases, and the supporting effect on the battery pack 6 is better.

In some embodiments, the second subsection 44 is configured as a constant-section beam, and the cross-sectional area of the second subsection 44 is equal to the cross-sectional area of the large end of the first subsection 43 . In this way, the connection strength between the second subsection 44 and the sinking section 8 can be increased, and since the second subsection 44 is closer to the sinking section 8 than the first subsection 43, the deformation resistance of the second subsection 44 can be increased. and destructive capabilities. In addition, the rear part of the battery pack 6 is assembled on the second subsection 44, and the second subsection 44 is a constant-section beam, so the upper surface of the second subsection 44 is horizontal, and the bending resistance of the second subsection 44 is The strength is improved, so that the assembly of the second subsection 44 and the battery pack 6 is more stable.

In some embodiments, the rear support section 11 includes a connected rear support front section 45 and a rear support rear section 46, the rear support front section 45 connects the rear support rear section 46 and the sinking section 8, and the cross section of the rear support front section 45 is the same as the rear support section 45. The cross-sections of the support rear sections 46 are not equal. In this implementation, the rear end of the sinking section 8 is sequentially connected to the rear support front section 45 and the rear support rear section 46, and the rear support front section 45 and the rear support rear section 46 are used for assembling the filter 28, the recovery oil tank 32, the reel 25 and Refueling pipeline assembly 3. The cross-section of the front rear support section 45 gradually decreases from front to rear, that is, the bottom surface of the front rear support section 45 gradually slopes upward from front to rear. Due to the concentration of stress at the sinking section 8 of the pipeline refueling truck 1, the weight on the chassis girder 5 is concentrated on the sinking section 8 and the vicinity of the sinking section 8. Therefore, the rear support front section 45 close to the sinking section 8 is set to gradually Tilt upwards to avoid the weight of the entire vehicle from being concentrated on the sinking section 8 and its vicinity, thereby improving the stability of the entire vehicle.

In some embodiments, the front rear support section 45 is configured as a variable-section beam, and the cross section of the front rear support section 45 gradually decreases from front to back. The rear support front section 45 is a variable-section beam. Since the rear support front section 45 is closer to the sinking section 8 than the rear support rear section 46, the ability of the rear support front section 45 to resist deformation and damage can be increased. Moreover, the rear end of the front rear support section 45 is far from the sinking section 8, and the rear end of the front support section 45 has a smaller section, which can reduce the manufacturing materials of the chassis frame 5, save resources and reduce the weight of the chassis frame 5 itself.

In some embodiments, the rear support section 46 is set as a constant-section beam, and the cross-sectional area of the rear support section 46 is equal to the cross-sectional area of the large end of the rear support front section 45, so that the rear support section 46 can bear the load. , reduce the weight of the rear section 46 of the rear support. That is to say, the upper surface of the rear support section 46 is horizontal, so that the bending strength of the rear support section 46 is increased, so that part of the bodywork assembly 4 assembled on the rear support section 46 is more stable.

In some embodiments, the sinking section 8 is located at 2/3 of the chassis frame 5 , and the midpoint of the chassis frame 5 is located at the front end of the midpoint of the sinking section 8 . In this way, the lifting platform 7 assembled at the sinking section 8 is set close to the driver's cab 12 without being assembled at the tail end of the rear support section 11, which optimizes the layout of the vehicle and prevents part of the lifting platform 7 from being in a suspended state, causing the vehicle to flick question.

The gravity threshold may be the driver's minimum weight. For example, if the weight of an adult is more than 50kg, when the gravity value detected by the gravity sensor 159 is greater than or equal to 50kg, it means that the driver is sitting on the driver's seat, immediately or driving, and then controls the multi-in-one controller 143 to turn the battery pack 6 The electrical energy of is distributed to the exercise motor 112. When the gravity value detected by the gravity sensor 159 is less than 50 kg, it means that the driver has left the driver's seat, and then the all-in-one controller 143 is controlled to distribute the electric energy of the battery pack 6 to the bodywork drive motor 113 . In this way, by setting the gravity sensor 159 , the all-in-one controller 143 can reasonably distribute the electric energy of the battery pack 6 .

In some embodiments, the vehicle controller 142 is configured to control the all-in-one controller 143 to transfer the electric energy of the battery pack 6 to Assigned to the traveling motor 112.

When the pipeline refueling vehicle 1 is in the driving state, and the gravity value detected by the gravity sensor 159 is less than the gravity threshold in a short period of time (for example, 1s or 2s), it means that the driver on the driver's seat is in a relatively short period of time during the driving state. In a short period of time, the body leaves the driver's seat but immediately sits on the driver's seat. Therefore, the vehicle controller 142 needs to control the all-in-one controller 143 to continue to distribute the electric energy of the battery pack 6 to the traveling motor 112 .

In this embodiment, when the gravity sensor 159 detects that the gravity value on the driver's seat is greater than the gravity threshold, and the key recognition sensor 160 detects that the car start key is in the start position, it means that the driver is sitting on the driver's seat and is driving or preparing to drive. Vehicle, therefore, the vehicle controller 142 controls the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the traveling motor 112 .

Further, the vehicle controller 142 controls the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the bodywork drive motor 113 according to the signal sent by the key recognition sensor 160 . Or when the key recognition sensor 160 detects that the car start key is not in the start position, it means that the driver will not be ready to drive the vehicle, and the pipeline refueling vehicle 1 does not need to refuel the aircraft. The corresponding signal sent by the sensor 160 controls the all-in-one controller 143 to power off the battery pack 6, the traveling motor 112 and the bodywork driving motor 113.
