[0031] The utility model relates to the technical field, in particular to a frame structure.

[0032] like Figure 1-4As shown, a frame structure proposed in the present application is suitable for fixing and supporting a refueling robot 4, wherein the refueling robot 4 includes a first mechanical arm 41; the frame structure includes an upper frame 1, a lower frame 2, and a first supporting structure 31, wherein the upper frame 1 is arranged at the upper part of the entire frame structure, the lower frame 2 is arranged at the lower part close to the ground, the first supporting structure 31 is arranged between the upper frame 1 and the lower frame 2, and the first supporting structure 31 is arranged in the first direction of the first mechanical arm 41; wherein, in the vertical direction, the first supporting structure 31 has a shape that is narrow in the middle and wide on both sides, so that the first mechanical arm 41 does not interfere with the first supporting structure 31 when it is fully extended in the first direction. The first direction refers to the direction from the first mechanical arm to the first supporting structure. The unique shape of the first support structure 31 proposed in the present application, which is narrow in the middle and wide on both sides, can not only provide fixation and support for the refueling robot 4, but also reduce the collision between the first mechanical arm of the robot 4 and the first support structure when unfolded, thereby increasing the service life of the refueling robot and reducing the overall horizontal size of the frame structure, saving manufacturing materials, reducing costs, and reducing the occupied area of ​​the overall frame structure during installation, thereby increasing the utilization rate of the installation site.

[0033] In some embodiments, in the frame structure, the frame structure further includes a second support structure 32 sandwiched between the upper frame 1 and the lower frame 2, and the second support structure 32 is arranged in the second direction of the first mechanical arm 41, and the second direction is opposite to the first direction. The first support structure 31 and the second support structure 32 are respectively arranged vertically at both ends of the lower frame 2 and extend upward, and jointly support the upper frame and other structures arranged in the upper frame, such as a control unit, etc.

[0034] In some embodiments, in the frame structure, the refueling robot 4 includes a second mechanical arm 42, which is arranged on both sides of the trunk of the refueling robot 4 opposite to the first mechanical arm 41, and the second support structure 32 has a receiving space on the side close to the second mechanical arm 42, so that the second mechanical arm 42 does not interfere with the second support structure 32 when it is fully deployed in the second direction. The provision of the side receiving space of the second support structure 32 reduces the lateral size of the frame structure and reduces the manufacturing cost. At the same time, the receiving space can smoothly allow the second mechanical arm to be deployed in the second direction, avoiding the collision between the second mechanical arm and the second support structure, and improving the service life of the second mechanical arm and the entire refueling robot.

[0035] In some embodiments, in the frame structure, the first support structure 31 includes a vertically arranged first column 311, a second column 312 and a horizontally arranged first beam 313, and the first beam 313 is simultaneously connected to the first column 311, the second column 312 and the upper frame 1; the second support structure 32 includes a vertically arranged third column 321, a fourth column 322 and a horizontally arranged second beam 323, and the second beam 323 is simultaneously connected to the third column 321, the fourth column 322 and the upper frame 1; wherein the distance between the first column 311 and the second column 312 is smaller than the distance between the third column 321 and the fourth column 322. The width between the columns of the first support structure is smaller than the width between the columns of the second support structure, that is, the width between the columns constituting the first support structure is relatively small. When the first mechanical arm is unfolded toward the first support structure along the first horizontal direction, the narrow shape design in the middle of the first support structure makes the horizontal movement of the first mechanical arm in the first direction unaffected; the distance between the columns constituting the second support structure is relatively large, which can provide a larger area of ​​support for the upper frame. By setting two different groups of columns and beams, reasonable avoidance design is performed locally without weakening the strength of the overall support structure, thereby improving the availability of the frame support structure. In some embodiments, transverse reinforcing ribs are also provided between the first column 311 and the second column 312, and between the third column 321 and the fourth column 322, respectively, to strengthen the overall support strength. In some embodiments, the heights of the first column, the second column, the third column, and the fourth column are the same, and the heights of the first beam and the second beam are the same. The first support structure and the second support structure thus obtained support a common plane, that is, the lower side of the upper frame is located on a plane, and the overall force is more uniform.

[0036] In some embodiments, in the frame structure, the first support structure 31 further includes four first diagonal braces 314, which are located outside the first column 311 and the second column 312, and are used to connect the first column 311 with the first beam 313, the second column 312 with the first beam 313, the first column 311 with the lower frame 2, and the second column 312 with the lower frame 2. In some embodiments, the four first diagonal braces are symmetrically arranged about the geometric center of the first support structure. In the first support structure, the first beam is fixedly connected to the lower side of the upper frame, and the arrangement of the four first diagonal braces further strengthens the connection between the first support structure and the upper frame and the lower frame, improves the overall support strength of the first support structure, and increases the load-bearing weight of the upper frame.

[0037] In some embodiments, in the frame structure, the second support structure 32 further includes four second diagonal braces 324, which are located on the inner sides of the third column 321 and the fourth column 322, and are used to connect the third column 321 with the second beam 323, the fourth column 322 with the second beam 323, the third column 321 with the lower frame 2, and the fourth column 322 with the lower frame 2. In some embodiments, the four second diagonal braces are symmetrically arranged about the geometric center of the second support structure. In the second support structure, the second beam is fixedly connected to the lower side of the upper frame, and the arrangement of the four second diagonal braces further strengthens the connection between the second support structure and the upper frame and the lower frame, improves the overall support strength of the second support structure, and increases the load-bearing weight of the upper frame.

[0038] In some embodiments, in the frame structure, the second support structure 32 further includes a shell 325 located outside the third column 321, the fourth column 322 and the second crossbeam 323; the shell 325 includes a base 3251 and an extension 3252 extending from the base 3251 toward the first direction, the width of the extension 3252 in the third direction is smaller than the width of the base 3251 in the third direction, so as to form the accommodation space on both sides of the extension 3252; wherein the third direction is perpendicular to the first direction. The shell 325 is arranged on the outer side of the frame structure relative to the other side of the first support structure, and the extension 3252 extends from the base 3251 toward the geometric center of the frame. The width of the extension 3252 is smaller than the width of the base 3251, and the extra space on both sides of the extension and the outline of the base constitute the accommodation space, which is conducive to the second robot arm to fully unfold without interference when moving in the second direction. In some embodiments, the third column 321, the fourth column 322 and the second crossbeam 323 are located in the base 3251, and the extension 3252 is suitable for installing the oil engine. In some embodiments, a circular arc transition is provided at the right angle between the extension and the base. The space of the second support structure is reasonably utilized, and the oil engine is installed inside the second support structure 32. The extension outside the oil engine and the base outside the third column and the fourth column together form a shell. The integrated structure design is more aesthetically pleasing and can protect the oil engine in case of fire.

[0039] In some embodiments, in the frame structure, the refueling robot 4 includes a foldable support motion platform; in the folded state, the distance from the geometric center of the foldable support motion platform to the first column 311 in the horizontal direction is smaller than the distance from the geometric center of the foldable support motion platform to the third column 321. The oil engine is arranged between the column of the second support structure and the refueling robot, and a receiving space is arranged outside the oil engine. When the second mechanical arm is fully extended, the end of the second mechanical arm is suitable for moving in the receiving space; when the first mechanical arm is fully extended, the end of the first mechanical arm is suitable for moving on both sides of the middle part of the first support structure. The positional relationship between the foldable support motion platform, the first support structure, and the second support structure of the refueling robot is further rationally planned to facilitate the extension of the mechanical arms on both sides of the robot.

[0040] In some embodiments, in the frame structure, the bottom of the lower frame 2 is provided with a plurality of bottom flanges 21 extending outward from the bottom edge of the lower frame 2 in the third direction, and the frame structure is fixed to the ground of the gas station through anchor bolts passing through the bottom flanges 21. The anchor bolts are used to fix the connection to prevent the refueling robot from shaking during the refueling process, thereby causing errors in the accuracy of the manipulator, causing errors in the motion trajectory, and affecting the refueling effect.

[0041] In some embodiments, in the frame structure, the middle width L of the first support structure 31 satisfies 200mm≤L≤400mm. The outer shell material of the outer surface of the upper frame, the lower frame, the first support structure, and the second support structure is an aluminum alloy skin to improve the aesthetics. Reinforcement beams, oblique beams, reinforcement ribs, etc. are also provided between the interior of the upper frame and the lower frame to improve the strength of the overall frame structure; the steel structure in the upper frame, the lower frame, and the support structure is made of high-strength steel.
