Description

Technical Field

[0001] This utility model relates to a positioning and installation device for the hinge pin of a charging door, belonging to the technical field of charging door installation. Background Technology

[0002] Vehicles have not only improved people's quality of life but also provided convenience for travel. Under the pressure of energy and environmental protection, new energy vehicles have undoubtedly become the future direction of automobile development. For new energy vehicles, the charging port is a frequently used area. The charging port of a new energy vehicle has the function of protecting the charging port, and we use it every time we charge a new energy vehicle.

[0003] The charging door includes a housing, a cover plate, a hinge pin for hinged connection between the housing and the cover plate, and a torsion spring. The cover plate has a gooseneck, the housing has a hinge part with a hinge hole for the hinge pin to pass through, and the gooseneck has a hinge hole for the hinge pin to pass through. The gooseneck is installed at the hinge part, the hinge pin is inserted into the hinge hole, and then the torsion spring is installed to complete the assembly of the charging door.

[0004] Currently, most charging gates are assembled manually. Manual assembly is labor-intensive, involving the manual insertion of hinge pins, and also suffers from inconsistent quality due to human error, sometimes resulting in improper assembly. Therefore, it is proposed to automate the installation of the hinge pins in the charging gate assembly process. Hinge pin positioning is fundamental to automated installation; therefore, solving the hinge pin positioning problem is essential for achieving automated installation. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a positioning and installation device for the hinge pin of a charging door.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning and installation device for a hinge pin of a charging door includes a fixed mounting platform set on a frame. The fixed mounting platform is provided with a pin positioning station. The hinge pin includes a positioning end and a free end. A positioning protrusion is provided on the outer wall of the positioning end. A bearing platform for supporting the positioning end and a positioning groove adapted to the positioning protrusion are provided on the fixed mounting platform corresponding to the pin positioning station.

[0007] The beneficial effects of this utility model are as follows: By placing the hinge pin on the pin positioning station, with the positioning end of the hinge pin supporting the bearing platform and the positioning protrusion of the hinge pin placed in the positioning groove, the hinge pin can be supported and positioned. The free end of the hinge pin is then ready to be inserted into the hinge hole of the charging door, preparing for the automated assembly of the hinge pin. The subsequent process can involve the charging door moving closer to the positioned hinge pin, or the positioned hinge pin moving closer to the charging door, allowing the free end of the hinge pin to be inserted into the hinge hole of the charging door housing. This utility model has a simple structure, is easy to operate, and can stably position the hinge pin, preparing for the subsequent automated installation of the hinge pin.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a lifting mechanism for the lifting and lowering action of the mounting platform, the mounting platform being connected to the frame via the lifting mechanism.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the mounting platform can be set on the frame by a lifting mechanism. After the hinge pin is positioned, the lifting mechanism can be used to lift the mounting platform and move it towards the charging door, so that the hinge pin can be automatically installed in the hinge hole of the charging door.

[0011] Furthermore, the lifting mechanism includes a lifting electric cylinder, the piston rod of which is connected to the fixed mounting platform, and the cylinder body of which is mounted on the frame.

[0012] The advantages of adopting the above-mentioned further solutions are that the lifting mechanism can specifically adopt a lifting electric cylinder, which has high control precision and accuracy, can support complex motion trajectories, has low cost, and is flexible in configuration.

[0013] Furthermore, it also includes a platform guiding mechanism for guiding the lifting and lowering of the fixed assembly platform. The platform guiding mechanism includes at least two guide rods, which are disposed on the fixed assembly platform. The frame is provided with guide holes or guide sleeves for the lifting and lowering of the guide rods.

[0014] The beneficial effects of adopting the above-mentioned further solution are that it limits and guides the lifting action of the fixed installation platform, ensuring that the fixed installation platform lifts and lowers smoothly, while also reducing the radial force on the lifting cylinder of the lifting mechanism and extending the service life of the lifting mechanism.

[0015] Furthermore, the mounting platform is also equipped with a detection sensor for detecting whether there is a hinge pin at the pin positioning station.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the detection sensor detects a hinge pin at the pin positioning station, and the detection sensor transmits the signal to the control system. The control system will control the lifting mechanism to lift the pin so as to insert the hinge pin into the hinge hole of the charging door.

[0017] Furthermore, the hinge hole of the charging door is pre-installed with a guide shaft, and also includes a pin constraint mechanism for constraining the free end of the hinge pin when the hinge pin is connected to the guide shaft. The pin constraint mechanism is mounted on the frame.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, during assembly, the free end of the hinge pin will mate with the guide shaft pre-installed in the hinge hole of the charging door. Since the guide shaft will exert force on the free end of the hinge pin during the mate process, there will be a problem affecting the positioning stability of the hinge pin. Therefore, a pin constraint mechanism is set up. When the hinge pin mates with the guide shaft, the pin constraint mechanism can constrain the part of the hinge pin near the free end, thereby solving the problem of the hinge pin's stability when mates with the guide shaft, thus meeting the requirements of the hinge pin's assembly stability and assembly quality.

[0019] Furthermore, the pin constraint mechanism includes a pair of constraint clamps and a constraint cylinder for driving the pair of constraint clamps to clamp or release. When the pair of constraint clamps clamp, they can form a constraint hole for the free end of the hinge pin to pass through.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the pin constraint mechanism is a pair of constraint clamps. When the free end of the hinge pin is close to the guide shaft, the constraint clamps can hold it under the action of the constraint cylinder to form a constraint hole for the hinge pin to pass through. The free end of the hinge pin passes through the constraint hole and then docks with the guide shaft. The constraint hole can constrain the upper part of the hinge pin, thus ensuring the stability and positioning accuracy of the hinge pin when docking with the guide shaft. This avoids the problem of inaccurate positioning of the hinge pin due to docking with the guide shaft, and makes full preparation for the subsequent hinge pin to push the guide shaft out and insert into the hinge hole of the charging door.

[0021] Furthermore, it also includes an adjusting cylinder for adjusting the position of the pin restraint mechanism, the pin restraint mechanism being connected to the frame via the adjusting cylinder.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the pin constraint mechanism must be able to solve the problem of stable positioning when the articulated pin is connected, while the pin constraint mechanism must not hinder the assembly of the articulated pin. Therefore, the position of the pin constraint mechanism is designed to be adjustable. When needed, the pin constraint mechanism can move to the pin constraint working position. After the articulated pin is connected with the guide shaft, the pin constraint mechanism can be withdrawn from the pin constraint working position in time, and the articulated pin can continue to move until it pushes out the guide shaft to complete the assembly of the articulated pin.

[0023] Furthermore, the insertion end of the constraint hole has a trumpet-shaped structure.

[0024] The advantage of adopting the above-mentioned further solution is that it facilitates the smooth insertion of the free end of the hinge pin, and allows it to dock with the guide shaft of the pre-installed charging door through the constraint hole and push the guide shaft out to complete the automatic installation of the hinge pin.

[0035] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0036] Example 1, such as Figures 1-3 and Figure 9As shown, a positioning and installation device for a hinge pin of a charging door includes a mounting platform 2 set on a frame 1. The mounting platform 2 is provided with a pin positioning station. The hinge pin 5 includes a positioning end 52 and a free end 53. A positioning protrusion 51 is provided on the outer wall of the side of the positioning end 52. A support platform 3 for supporting the positioning end 52 and a positioning groove 4 adapted to the positioning protrusion 51 are provided on the mounting platform 2 corresponding to the pin positioning station.

[0037] The assembly platform 2 is also equipped with a detection sensor 8 for detecting whether there is a hinge pin 5 at the pin positioning station. The detection sensor 8 can detect whether the hinge pin 5 is in place; if it is, the subsequent automatic assembly process can begin. A laser sensor can be used as the detection sensor 8.

[0038] Example 2, as Figure 4 and Figure 5 As shown, it also includes a lifting mechanism for the lifting and lowering action of the mounting platform 2, and the mounting platform 2 is connected to the frame 1 through the lifting mechanism. The mounting platform 2 can be mounted on the frame 1 through the lifting mechanism, so that after the hinge pin 5 is positioned, the lifting mechanism can be activated, and the mounting platform 2 can carry the hinge pin 5 and move towards the charging door 14, so that the hinge pin 5 can be automatically installed in the hinge hole 143 of the charging door 14.

[0039] The lifting mechanism includes a lifting electric cylinder 6, the piston rod of which is connected to the fixed mounting platform 2, and the cylinder body of which is mounted on the frame 1. Specifically, the lifting mechanism can employ a lifting electric cylinder 6, which offers high and accurate control, supports complex motion trajectories, is low in cost, and offers flexible configuration.

[0040] It also includes a platform guiding mechanism for guiding the lifting and lowering of the fixed mounting platform 2. The platform guiding mechanism includes at least two guide rods 7, which are disposed on the fixed mounting platform 2. The frame 1 is provided with guide holes or guide sleeves for the lifting and lowering movement of the guide rods 7. This mechanism limits and guides the lifting and lowering movement of the fixed mounting platform 2, ensuring smooth lifting and lowering, while also reducing the radial force on the lifting cylinder 6 of the lifting mechanism and extending the service life of the lifting mechanism.

[0041] The detection sensor 8 detects a hinge pin 5 at the pin positioning station. The detection sensor 8 transmits a signal to the control system, which then controls the lifting mechanism to lift the hinge pin 5 into the hinge hole 143 of the charging door 14. The remaining structure is the same as in Embodiment 1, and will not be described further here.

[0042] Example 3, as Figures 6-9As shown, the hinge hole 143 of the charging door 14 is pre-installed with a guide shaft 13, and also includes a pin constraint mechanism for constraining the free end 53 of the hinge pin 5 when it mates with the guide shaft 13. The pin constraint mechanism is mounted on the frame 1. During assembly, the free end 53 of the hinge pin 5 mates with the pre-installed guide shaft 13. Since the guide shaft 13 applies force to the free end 53 of the hinge pin 5 during the mate process, it may affect the positioning stability of the hinge pin 5. Therefore, a pin constraint mechanism is provided. At the same time as the hinge pin 5 mates with the guide shaft 13, the pin constraint mechanism can act to constrain the part of the hinge pin 5 near the free end. In this way, the hinge pin 5 will not become unstable in positioning due to the received force, thus solving the problem of the hinge pin 5's stability when mates with the guide shaft 13, thereby meeting the requirements of the hinge pin 5's assembly stability and assembly quality.

[0043] The pin constraint mechanism includes a pair of constraint clamps 10 and a constraint cylinder 9 for driving the clamping or releasing action of the pair of constraint clamps 10. When the pair of constraint clamps 10 clamp, they can form a constraint hole 11 for the free end 53 of the hinge pin 5 to pass through. The pin constraint mechanism is a pair of constraint clamps 10, so that when the free end 53 of the hinge pin 5 approaches the guide shaft 13, the constraint clamps 10 can hold the constraint hole 11 formed for the hinge pin 5 to pass through under the action of the constraint cylinder 9. As the free end 53 of the hinge pin 5 passes through the constraint hole 11 and then docks with the guide shaft 13, the constraint hole 11 can constrain the hinge pin 5. This ensures the stability and positioning accuracy of the hinge pin 5 when docking with the guide shaft 13, avoiding the problem of inaccurate positioning of the hinge pin 5 due to docking with the guide shaft 13, and fully preparing for the subsequent hinge pin 5 to push the guide shaft 13 out and insert into the hinge hole 143 of the charging door 14.

[0044] It also includes an adjusting cylinder 12 for adjusting the position of the pin restraint mechanism, which is connected to the frame 1 via the adjusting cylinder 12. The pin restraint mechanism must solve the problem of stable positioning during the mating of the hinge pin 5, while also not hindering the assembly of the hinge pin 5. Therefore, the position of the pin restraint mechanism is designed to be adjustable, so that it can be moved to the pin restraint working position when needed, such as... Figure 6 and Figure 7 The pin constraint mechanism shown in the image is in the pin constraint working position, waiting for the articulated pin 5 to be connected with the guide shaft 13; the lifting electric cylinder 6 is activated, and the installation platform carries the articulated pin 5 upward, as shown in the image. Figure 7The diagram shows the hinge pin 5 in an upward-moving state. As the hinge pin 5 moves upward, its free end 53 connects with the guide shaft 13 through the constraint hole 11. During the connection process, the pin constraint mechanism supports the upper part of the hinge pin 5, preventing the guide shaft 13 from applying force to the hinge pin 5 during the connection process, thus ensuring the stability of the hinge pin 5's positioning. Figure 8 As shown, the hinge pin 5 is in the state of passing through the constraint hole 11. After the hinge pin 5 and the guide shaft 13 are stably connected, the hinge pin 5 still needs to move upward and insert into the hinge hole 143 of the charging door 14. In order to avoid the pin constraint mechanism affecting the upward movement of the hinge pin 5, the pin constraint mechanism can be withdrawn from the pin constraint working position in time by adjusting the action of the cylinder 12. The hinge pin 5 can continue to move until it pushes out the guide shaft 13 to complete the assembly of the hinge pin 5.

[0045] The insertion end of the constraint hole 11 has a trumpet-shaped structure. This facilitates the smooth insertion of the free end 53 of the hinge pin 5 through the constraint hole 11, allowing it to align with the guide shaft 13 of the pre-installed charging door 14 and push the guide shaft 13 out to complete the automatic installation of the hinge pin 5. The remaining structure is the same as in Embodiment 1 or Embodiment 2, and will not be described further here.

[0046] This utility model positions the housing 141 and cover plate 142 of the charging door 14 pre-installed with the guide shaft 13. The hinge pin 5 is placed at the pin positioning station, with the positioning end 52 of the hinge pin 5 supporting the support platform 3. The positioning protrusion 51 of the hinge pin 5 is placed in the positioning groove 4, achieving support and positioning of the hinge pin 5. After the detection sensor 8 detects the positioning, it transmits a signal to the control system. The control system controls the action of the lifting cylinder 6. Under the action of the lifting cylinder 6, the mounting platform 2 rises towards the charging door 14, and the constraint clamp 10 located at the pin constraint station clamps the door. The free end 53 of the hinge pin 5 passes through the constraint hole 11 and then connects with the guide shaft 13. The constraint clamp 10 can stabilize the hinge pin 5 during the connection process. As the hinge pin 5 continues to move upward, the hinge pin 5 pushes the guide shaft 13 upward and is inserted into the hinge hole 143. The constraint clamp 10 is released and withdrawn from the pin constraint position under the action of the adjusting cylinder 12 to avoid interfering with the installation of the hinge pin 5. Until the free end 53 of the hinge pin 5 pushes the guide shaft 13 out, the installation of the hinge pin 5 in the hinge hole 143 of the charging door 14 is completed, realizing the automated assembly of the hinge pin 5.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
