Technical Field

[0001] The utility model relates to the technical field of hydrogen filling machines, in particular to an axial rotation structure for fixing a hydrogen filling gun bracket and a hydrogen filling device. Background Art

[0002] The hydrogen filling gun is a special and important component of the hydrogen filling machine, which is responsible for filling hydrogen into the hydrogen fuel vehicle. The hydrogen filling gun is installed at the end of the hydrogen filling hose of the hydrogen filling machine and is usually fixed on the hydrogen filling gun bracket of the hydrogen filling machine. When a hydrogen fuel vehicle needs to be filled, the hydrogen filling operator needs to take out the hydrogen filling gun from the hydrogen filling gun bracket, connect it to the filling interface on the hydrogen fuel vehicle, and then carry out the hydrogen filling work.

[0003] Generally, the hydrogen filling gun bracket is installed on the side plate of the hydrogen filling machine through bolt connection to stably fix the hydrogen filling gun. The conventional hydrogen filling gun bracket is a fully fixed type and cannot rotate relative to the hydrogen filling machine itself. And the hydrogen filling gun is fixed on the hydrogen filling gun bracket and cannot rotate relative to the hydrogen filling gun bracket either, which limits the operator's posture and movement. The operator must adopt a certain specific posture to conveniently take out the hydrogen filling gun, then turn it to near the filling port of the hydrogen fuel vehicle, insert the hydrogen filling gun into the filling port of the hydrogen fuel vehicle, and carry out the hydrogen filling operation; it takes time to adjust the posture and stand directly in front of the hydrogen filling gun bracket and the hydrogen filling gun to be convenient for operation, and it is not convenient to operate on the side.

[0004] Therefore, the conventional hydrogen filling gun bracket is fixedly arranged on the hydrogen filling machine and cannot rotate itself, resulting in inconvenient operation during the hydrogen filling process. Summary of the Utility Model

[0005] One technical problem to be solved by the utility model is that: since the existing hydrogen filling gun bracket is fixedly arranged on the side plate of the hydrogen filling machine and the hydrogen filling gun bracket is a fully fixed type and cannot rotate relative to the hydrogen filling machine itself, it is necessary to adjust the operation angle relative to the hydrogen filling gun during the hydrogen filling process and maintain a fixed posture to complete the operation, resulting in inconvenient use.

[0006] To solve the above technical problem, an embodiment of the utility model provides an axial rotation structure for fixing a hydrogen filling gun bracket.

[0007] The axial rotation structure includes: a mounting back plate, a mounting member sleeved in the mounting back plate for fixing the hydrogen filling gun bracket, and a rotating shaft connecting member connecting the mounting back plate and the mounting member;

Furthermore, it solves the technical problem that because the existing hydrogenation gun bracket is fixedly arranged on the side plate of the hydrogenation machine, and the hydrogenation gun bracket is fully fixed and cannot rotate relative to the hydrogenation machine itself, resulting in the need to adjust the operation angle relative to the hydrogenation gun during the hydrogenation process and maintain a fixed posture to complete the operation, which is inconvenient to use.

[0033] Such as Figures 1 to 3As shown in the figure, the present utility model provides an axial rotation structure for fixing a hydrogenation gun bracket. The axial rotation structure includes a mounting backplate 1, a mounting member 2 sleeved in the mounting backplate 1 for fixing the hydrogenation gun bracket 6, and a rotating shaft connecting member 3 connecting the mounting backplate 1 and the mounting member 2. The mounting backplate 1 is U-shaped, including side plates 101, a top plate 102, and a bottom plate 103. The side plates 101 are provided with screw holes for fixed installation with the side plates of the hydrogenation machine 5. The top plate 102 and the bottom plate 103 are oppositely provided with rotating shaft installation holes 104, and the central connection line of the rotating shaft installation holes 104 is parallel to the side plates 101. The mounting backplate 1 can be integrally formed or assembled by welding. The specific corners of the U-shape can be right angles or in a chamfered form.

[0034] The mounting member 2 includes a mounting plate 201 for fixing the hydrogenation gun bracket 6. The rotating shaft connecting member 3 is connected and arranged at the upper and lower ends of the mounting plate 201, and is arranged between the rotating shaft installation holes 104 of the top plate 102 and the bottom plate 103, and can rotate around the central connection line of the rotating shaft installation holes 104. Thus, after the mounting member 2 is connected to the hydrogenation gun 7, it can rotate relative to the mounting backplate 1 arranged on the side wall of the hydrogenation machine 5 under the drive of this axial rotation structure, thereby expanding the movable range of the operator during the hydrogenation operation. Specifically, it can axially rotate relative to the side plate of the hydrogenation machine 5 by 180°.

[0035] The axial rotation structure for fixing the hydrogenation gun bracket provided by the present utility model, by setting a U-shaped mounting backplate 1 fixedly installed with the side plate of the hydrogenation machine 5, and rotatably arranging the mounting member 2 for connecting with the hydrogenation gun bracket 6 in the mounting backplate 1 through the rotating shaft connecting member 3, enables the hydrogenation gun 7 to rotate around the side plate of the hydrogenation machine 5 by using this axial rotation structure 10 under the drive of the hydrogenation gun bracket 6, thereby expanding the operation space range of the hydrogenation personnel. Furthermore, it solves the technical problem that because the existing hydrogenation gun bracket is fixedly arranged on the side plate of the hydrogenation machine, and the hydrogenation gun bracket is fully fixed and cannot rotate relative to the hydrogenation machine itself, it is necessary to adjust the operation angle relative to the hydrogenation gun during the hydrogenation process and maintain a fixed posture to complete the operation, resulting in inconvenient use.

[0036] In an alternative embodiment of the present utility model, the rotating shaft mounting hole 104 has a polygonal structure, and a polygonal protrusion 301 is provided on one side of the rotating shaft connecting member 3 that is connected to the rotating shaft mounting hole 104. The matching polygonal settings of the rotating shaft mounting hole 104 and the rotating shaft connecting member 3 can effectively limit the position connection of the rotating shaft mounting hole 104 and the rotating shaft connecting member 3, thereby improving the stability of the structural connection. Further, the mounting backplane 1 and the rotating shaft connecting member 3 can be bolted to reinforce the stability of the overall structural connection. Preferably, the polygonal protrusion 301 and the rotating shaft mounting hole 104 are hexagons. To ensure the realization of the axial rotation of the mounting member 2, the connection between the mounting member 2 and the rotating shaft connecting member 3 is an axially rotatable connection at this time. For example, the mounting member 2 and the rotating shaft connecting member 3 can be bolted together.

[0037] In an alternative embodiment of the present utility model, the mounting member 2 includes a vertical mounting plate 201 and horizontal wing plates 202 provided at the upper and lower ends of the mounting plate 201. The mounting plate 201 is connected to the rotating shaft connecting member 3 through the horizontal wing plates 202, thereby improving the diversity of the connection form. While facilitating the installation of the mounting plate 201 and the hydrogen filling gun bracket 6, it can more effectively ensure the stability of its connection with the rotating shaft connecting member 3 to enable axial rotation.

[0038] In an alternative embodiment of the present utility model, a limit mounting hole 203 is provided on the horizontal wing plate 202. The limit mounting hole 203 is coaxially arranged with the rotating shaft mounting hole 104, and the rotating shaft connecting member 3 is correspondingly provided with a threaded protrusion 302 for passing through the limit mounting hole 203. At this time, the matching structure settings of the limit mounting hole 203 and the threaded protrusion 302 can enable the mounting member 2 to rotate around the rotating shaft connecting member 3 along the central axis of the limit mounting hole 203. The coaxial arrangement of the limit mounting hole 203 and the rotating shaft mounting hole 104 can make the rotation of the mounting member 2 in the mounting backplane 1 receive more uniform force, reduce friction loss, and thereby improve the service life.

[0039] In an alternative embodiment of the present utility model, a mounting boss 303 is provided on the abutting surface of the rotating shaft connecting member 3 for connecting the mounting member 2 to avoid damage to parts caused by friction loss during the installation process. In a further alternative embodiment of the present utility model, there are multiple mounting bosses 303, and the multiple mounting bosses 303 are evenly distributed along the radial direction of the rotating shaft connecting member 3, thereby improving the stability of the force on the abutting surface between the rotating shaft connecting member 3 and the mounting member 2 during use.

[0040] In an alternative embodiment of the present utility model, the axial rotation structure 10 includes a protective cover 4. The protective cover 4 encloses the mounting member 2 and the rotating shaft connecting member 3 to form a closed component protection space to prevent dust or other debris from entering the axial rotation structure 10 and interfering with the normal operation of the structure.

[0041] In a further optional embodiment of the present utility model, the protective cover 4 is bolted to the mounting plate 201. The protective cover 4 is provided with a dedicated connecting member for connecting to the mounting plate 201. And in order to prevent the protective cover 4 from affecting the rotation use effect and visual effect of the mounting member 2, preferably, the side of the protective cover 4 close to the mounting back plate 1 is an arc surface structure.

[0042] During the actual use process, as Figure 3 shown, an axial rotation structure 10 is provided on the side plate of the hydrogen refueling machine 5. The hydrogen refueling gun bracket 6 is fixed on the axial rotation structure 10. The hydrogen refueling gun 7 is placed on the hydrogen refueling gun bracket 6. And the hydrogen refueling personnel 8 can take the hydrogen refueling gun 7 within the range of rotating 90° to the left and 90° to the right in front of the hydrogen refueling machine 5 by using the axial rotation structure, so that the hydrogen refueling gun can be conveniently taken, without having to maintain a specific posture or specific angle, and the operation is simple and convenient to use.

[0043] The present utility model also provides a hydrogen refueling device, which includes a hydrogen refueling machine, a hydrogen refueling gun bracket and an axial rotation structure for fixing the hydrogen refueling gun bracket according to any one of the above. The mounting back plate of the axial rotation structure is arranged on the side plate of the hydrogen refueling machine, so that the hydrogen refueling gun can be rotatably arranged on the side plate of the hydrogen refueling machine through the hydrogen refueling gun bracket rotatably connected to the axial rotation structure.

[0044] The axial rotation structure for fixing the hydrogen refueling gun bracket in the hydrogen refueling device provided by the present utility model is provided with a U-shaped mounting back plate 1 fixedly installed on the side plate of the hydrogen refueling machine 5, and the mounting member 2 for connecting to the hydrogen refueling gun bracket 6 is rotatably arranged in the mounting back plate 1 through a rotating shaft connecting member 3, so that the hydrogen refueling gun 7 can rotate around the side plate of the hydrogen refueling machine 5 by driving the hydrogen refueling gun bracket 6 by using the axial rotation structure 10, thereby expanding the operation space range of the hydrogen refueling personnel. Furthermore, it solves the technical problem that because the existing hydrogen refueling gun bracket is fixedly arranged on the side plate of the hydrogen refueling machine and the hydrogen refueling gun bracket is fully fixed and cannot rotate relative to the hydrogen refueling machine itself, it is necessary to adjust the operation angle relative to the hydrogen refueling gun during the hydrogen refueling process and maintain a fixed posture to complete the operation, resulting in inconvenient use.
