Description

Technical Field

[0001] This utility model relates to an assembly device for a charging gate, belonging to the field of vehicle charging technology. Background Technology

[0002] Vehicles not only improve people's quality of life but also provide convenience for travel. Under the pressure of energy and environmental protection, new energy vehicles will undoubtedly become the future direction of automobile development. For new energy vehicles, there will be a small charging door at the charging port. The charging door has the function of protecting the charging port. The charging door is a place that is used frequently in new energy vehicles, and it will be used every time the new energy vehicle is charged.

[0003] The charging door includes a housing, a cover plate, a pin for hinged connection between the housing and the cover plate, and a torsion spring. The torsion spring is fitted onto the pin. The cover plate has a gooseneck, and the housing has a hinge part with a hinge hole for the pin to pass through. The gooseneck also has a hinge hole for the pin to pass through. To install the charging door, the gooseneck of the cover plate is installed onto the hinge part of the housing. Then, the pin is manually inserted into the hinge hole of the hinge part and the hinge hole of the gooseneck. Finally, the torsion spring is installed to complete the assembly of the charging door.

[0004] Currently, the installation of charging gates is mostly done manually. This is affected by the worker's skill level; skilled workers are more efficient, while less skilled workers are less efficient at inserting pins. Overall, manual installation is inefficient and labor-intensive, and it's difficult to perform batch production of charging gates manually. Furthermore, due to the limitations of human experience, the assembly quality of the charging gates is inconsistent, with instances of improper pin or torsion spring installation affecting the quality of the charging gates. Therefore, there is a need for charging gate assembly equipment that can improve assembly efficiency, reduce worker labor intensity, and meet the requirements for assembly quality and consistency. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an assembly device for a charging door.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An assembly equipment for a charging door includes a frame, a door positioning device disposed on the frame for positioning the charging door, and a pin positioning and installation device for positioning and installing the pin of the charging door; the door positioning device includes a shell positioning mechanism for positioning the shell of the charging door and a cover positioning mechanism for positioning the cover plate of the charging door; the pin includes a positioning end and a free end, and a positioning protrusion is provided on the outer wall of the positioning end; the pin positioning and installation device includes a mounting platform, a bearing platform disposed on the mounting platform for supporting the positioning end, and a positioning groove adapted to the positioning protrusion, the mounting platform being disposed on the frame;

[0007] It also includes a concentric guide mechanism for pre-positioning the pin insertion position on the charging door. The concentric guide mechanism includes a shaft positioning seat and a guide shaft. The shaft positioning seat is disposed on the frame and has a shaft hole concentric with the pin positioned on the bearing platform. The guide shaft can pass through the shaft hole and be inserted into the charging door to pre-position the hinge holes of the charging door housing and cover plate concentrically.

[0008] The beneficial effects of this utility model are as follows: the gooseneck on the cover of the charging door is pre-installed into the hinge part of the housing. Then, the pre-installed charging door housing is positioned on the housing positioning mechanism. The guide shaft, inserted into the shaft hole of the shaft positioning seat, can be manually inserted into the hinge hole of the pre-installed charging door. The guide shaft is manually controlled to pass through the hinge part and the hinge hole of the gooseneck. Real-time adjustment can be made by hand based on the alignment of the hinge part and the hinge hole of the gooseneck. This avoids the situation where the pin automatically inserts due to improper pre-installation of the charging door, which could damage the equipment, guide shaft, or charging door. Manual alignment is convenient, does not involve pins or torsion springs, and reduces the labor intensity of installation workers. After alignment, the cover of the charging door can be repositioned, ensuring easier adjustment during the alignment process. The shaft hole of the shaft positioning seat is concentric with the pin positioned on the bearing platform, ensuring concentricity during pin installation. The coaxial design avoids damage to the pins during the pressing process, ensuring the assembly quality of the pins. This invention not only achieves automatic installation of the pins but also automatic installation of the torsion spring. The torsion spring is fitted onto the pin, with one end of the torsion spring engaging in the spring retainer. The positioning end of the pin rests on the support platform without hindering the fitting of the torsion spring. The positioning protrusion and positioning groove cooperate to position the pin. During installation, the pin approaches the charging door, and the free end of the pin pushes against the guide shaft. As the pin approaches the charging door, it continues to push the guide shaft out of the hinge hole. When the pin is inserted into the position to compress the torsion spring, the drive cylinder is activated, and the lever acts on the other end of the torsion spring to compress it. The pin continues to approach the charging door until it is fully inserted into the hinge hole. The pin installation is complete. The drive cylinder is then reset, and the other end of the torsion spring springs back to the spring mounting slot on the housing, completing the torsion spring installation. This invention enables concentric pre-alignment of the hinge holes of the pre-assembled charging door, ensuring that the pins are concentric and coaxial during installation, avoiding scratches during the pin pressing process, and guaranteeing the assembly quality of the pins. Simultaneously, it achieves automatic installation of the charging door's torsion spring, solving problems such as limited installation space, difficulty in manual installation, and the risk of injury. This automatic installation of the pins and torsion springs improves the assembly efficiency of the charging door, ensures the assembly quality and consistency of the charging door, reduces the labor intensity of workers, and is suitable for batch installation of charging doors.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, it also includes a torsion spring mounting mechanism for positioning and installing the torsion spring on the charging door. The torsion spring is fitted on the outside of the positioning end, and a spring retainer for positioning one end of the torsion spring is provided on the outer wall of the positioning end. The torsion spring mounting mechanism includes a lever for moving the other end of the torsion spring and a lever drive cylinder for driving the lever. The lever is rotatably mounted on the mounting platform, and the cylinder body of the lever drive cylinder is mounted on the mounting platform.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the installation space for the torsion spring on the charging door is small, making manual installation difficult and prone to hand injury, posing a risk of personal injury. Using this torsion spring mounting mechanism, the torsion spring can be fitted onto the outside of the positioning end of the pin, with one end of the torsion spring inserted into the spring retainer of the pin. Then, the pin with the torsion spring is placed on the mounting platform, with the positioning end of the pin supported on the bearing platform and the positioning protrusion of the pin placed in the positioning groove, thus achieving support and positioning of the pin with the torsion spring. After the pin with the torsion spring is positioned, the mounting platform is brought close to the positioned charging door, allowing the free end of the pin to be inserted into the hinge hole of the charging door. When the pin is inserted to the position of compressing the torsion spring, the drive cylinder is activated, driving the lever to act on the torsion spring. The other end of the spring compresses the torsion spring, and the pin continues to move closer to the charging door until the pin is fully inserted into the hinge hole of the charging door. Once the pin is installed, the drive cylinder is reset, and the other end of the torsion spring springs back into the spring mounting slot of the charging door housing. The torsion spring is then installed automatically, solving the problem of difficult manual installation of the torsion spring due to limited installation space. This improves the pressing efficiency of the pin and torsion spring, avoids the risk of personal injury caused by manual spring installation, improves the assembly efficiency and quality of the pin and torsion spring of the charging door, and reduces the labor intensity of workers.

[0012] Furthermore, the pin positioning and installation device also includes a platform lifting mechanism for lifting the fixed platform. The platform lifting mechanism includes a lifting drive cylinder, and the fixed platform is connected to the frame through the lifting drive cylinder.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the installation of the charging door can be a positioning of the charging door moving, that is, the positioned charging door moving towards the pin and torsion spring, or it can be the pin and torsion spring moving, that is, the positioned pin and torsion spring moving towards the charging door; the fixed installation platform is raised and lowered on the frame and the fixed installation platform is a movable setting. In this way, after the pin and torsion spring are positioned, the platform lifting mechanism is activated, and the fixed installation platform can carry the pin and torsion spring upward and move towards the positioned charging door, so as to realize the automated installation of the pin and torsion spring of the charging door.

[0014] Furthermore, it also includes a shaft seat drive cylinder for adjusting the position of the shaft positioning seat, the shaft positioning seat being mounted on the frame via the shaft seat drive cylinder.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the shaft positioning seat is mounted on the frame through a shaft positioning drive cylinder, and the piston rod of the shaft positioning drive cylinder is connected to the shaft positioning seat, or connected to the shaft positioning seat through a shaft mounting plate; the position of the shaft positioning seat can be adjusted by the shaft positioning drive cylinder; specifically, after the charging door is pre-installed, the traction shaft passing through the shaft hole of the shaft positioning seat can be manually inserted into the hinge hole of the charging door, and then the cover plate of the charging door is positioned. The shaft positioning seat can be manually pressed down so that it can move to the working position. The lower end face of the shaft positioning seat in the working position can act on the upper end face of the hinge hole of the positioned charging door. Then the pin and torsion spring of the charging door are installed, and the shaft positioning seat is manually pressed to the working position. The shaft positioning seat can be reset from the working position to the original position by the shaft positioning drive cylinder; of course, the positional change between the original position and the working position of the shaft positioning seat can also be adjusted by the shaft positioning drive cylinder.

[0016] Furthermore, the shaft positioning seat is connected to the frame or shaft seat drive cylinder via a slide rail.

[0017] The advantages of adopting the above-mentioned further solution are that the slide rail can be set on the frame or on the cylinder body of the shaft seat drive cylinder, and the shaft positioning seat has a slide groove or slider that matches the slide rail. The shaft positioning seat can slide along the length of the slide rail, reducing the radial force on the shaft seat drive cylinder, and the position of the shaft positioning seat relative to the frame can be guided, limited and adjusted by the slide rail. To facilitate the positioning of the charging door, the original position of the shaft positioning seat can be placed far away from the charging door. This makes it easier to install and place the charging door. After the charging door housing is positioned, the guide shaft, which is inserted into the shaft hole of the shaft positioning seat, is inserted into the hinge hole of the hinge part and the hinge hole of the gooseneck to align the housing and the cover plate concentrically. After the charging door housing and the cover plate are aligned, the cover plate is positioned. Then, the shaft positioning seat can move towards the charging door. For example, the shaft positioning seat can be manually pressed down, or the shaft positioning seat drive cylinder can be used to control the shaft positioning seat to move down. The end face of the shaft positioning seat abuts against the end face of the hinge hole of the charging door to achieve stable positioning of the shaft positioning seat. The slide rail setting makes operation more convenient and effortless, and also accurately guides and positions the guide shaft to ensure the pre-positioning effect of the guide shaft.

[0018] Furthermore, it also includes a pin constraint mechanism for constraining the pin when it is connected to the guide shaft. The pin constraint mechanism is located between the mounting platform and the shaft positioning seat and is mounted on the frame.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, during the actual assembly of the charging door, in order to ensure that the pin can be accurately inserted into the hinge hole of the charging door, a guide shaft is pre-installed in the hinge hole of the charging door. In this way, during the pin assembly, as long as the pin positioning and alignment are accurate, as the pin approaches the charging door, the free end of the pin will align with the pre-installed guide shaft. Then, the guide shaft is pushed out to complete the installation of the pin of the charging door. Since the guide shaft will exert force on the free end of the pin during the alignment process, there may be a problem that affects the positioning stability of the pin. Therefore, a pin constraint mechanism is set up. When the pin aligns with the guide shaft, the pin constraint mechanism can act, and the free end of the pin can pass through the pin constraint mechanism. The pin constraint mechanism constrains and supports the pin rod part, solving the problem of the pin's stability when aligning with the guide shaft, thereby meeting the requirements of pin assembly stability and assembly quality.

[0020] Furthermore, the pin restraint mechanism includes a pair of restraint clamps and a restraint cylinder for driving the pair of restraint clamps to clamp or release. When the pair of restraint clamps clamp, they can form a restraint hole for the pin to pass through.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the pin constraint mechanism can specifically be a pair of constraint clamps. When the free end of the pin approaches the guide shaft, the constraint clamps can hold it under the action of the constraint cylinder to form a constraint hole for the pin to pass through. As the free end of the pin passes through the constraint hole and then docks with the guide shaft, the constraint hole can constrain and support the pin. This ensures the stability and positioning accuracy of the pin when it docks with the guide shaft, and makes full preparation for the subsequent pin to push the guide shaft out and insert into the hinge hole of the charging door.

[0022] Furthermore, it also includes an adjusting cylinder for adjusting the position of the pin constraint mechanism, the constraint cylinder of the pin constraint mechanism being connected to the frame via the adjusting cylinder.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the pin restraint mechanism must not only solve the problem of stable positioning when the pin is connected, but also not hinder the assembly of the pin. Therefore, the position of the pin restraint mechanism is designed to be adjustable. When needed, the pin restraint mechanism can be moved to the working position, that is, the adjusting cylinder can move the pin restraint mechanism to the working position. After the pin is connected, the pin restraint mechanism can also be withdrawn from the working position in time under the action of the adjusting cylinder, and the pin can continue to act until the guide shaft is pushed out to complete the assembly of the pin.

[0024] Furthermore, the mounting platform is also equipped with a pin detection sensor for detecting whether the pins on the bearing platform are in place.

[0025] The beneficial effect of adopting the above-mentioned further solution is that when the pin detection sensor detects the pin, the pin is positioned in place, and the pin detection sensor transmits the signal to the control system. The control system will then control the execution of subsequent actions, such as the lifting mechanism of the control platform, to achieve automated installation of the pin, torsion spring, and charging door.

[0026] Furthermore, the mounting platform is also equipped with a spring detection sensor for detecting whether the torsion spring on the pin is installed in place.

[0027] The beneficial effect of adopting the above-mentioned further solution is that, in order to ensure that the torsion spring on the pin is installed in place, a spring detection sensor is set up. Once the spring detection sensor detects the torsion spring, the torsion spring is positioned, and the spring detection sensor will transmit a signal to the control system. The control system will then control the execution of subsequent actions, such as controlling the lifting mechanism of the control platform to assemble the pin and torsion spring with the charging door. The position of the pin or torsion spring can be detected by setting a single pin detection sensor or a spring detection sensor. Of course, both pin detection sensors and spring detection sensors can be set simultaneously to more accurately ensure that both the pin and the torsion spring are in place.

[0028] Furthermore, the shell positioning mechanism includes a shell positioning groove and a shell positioning component for positioning the shell on the shell positioning groove, wherein the shell positioning groove is adapted to the shape of the shell.

[0029] The beneficial effect of adopting the above-mentioned further solution is that the housing of the charging door can be placed in the housing positioning groove, and the housing positioning groove is consistent with the outer contour of the housing of the charging door, which can achieve accurate and stable positioning of the housing. Then, the housing can be pressed into the housing positioning groove by the housing positioning assembly, thereby achieving stable positioning of the housing of the charging door.

[0030] Furthermore, the cover positioning assembly includes a positioning suction cup disposed on the frame for adsorbing the cover plate.

[0031] The beneficial effect of adopting the above-mentioned further solution is that, after the guide shaft is inserted into the hinge hole of the charging door hinge and the gooseneck, the cover plate of the charging door can be adsorbed onto the frame by the positioning suction cup after alignment, thereby realizing the positioning of the charging door cover plate. The cover plate positioning is convenient and quick, improving the positioning efficiency of the charging door. Attached Figure Description

[0055] 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.

[0056] like Figures 1-22 As shown, an assembly device for a charging door includes a frame 1, a door positioning device mounted on the frame 1 for positioning a charging door 29, and a pin positioning and installation device for positioning and installing a pin 30 for the charging door 29. The door positioning device includes a shell positioning mechanism for positioning a housing 291 of the charging door 29 and a cover positioning mechanism for positioning a cover plate 292 of the charging door 29. The pin 30 includes a positioning end and a free end 303, and a positioning protrusion 301 is provided on the outer wall of the positioning end. The pin positioning and installation device includes a mounting platform 2, a support platform 3 mounted on the mounting platform 2 for supporting the positioning end, and a positioning groove 4 adapted to the positioning protrusion 301. The mounting platform 2 is mounted on the frame 1.

[0057] It also includes a concentric guide mechanism for pre-positioning the insertion position of the pin 30 on the charging door 29. The concentric guide mechanism includes a shaft positioning seat 13 and a guide shaft 12. The shaft positioning seat 13 is disposed on the frame 1. The shaft positioning seat 13 is provided with a shaft hole concentric with the pin 30 positioned on the support platform 3. The guide shaft 12 can pass through the shaft hole and be inserted into the charging door 29 to pre-position the hinge hole 293 of the housing 291 and the cover plate 292 of the charging door 29 concentrically.

[0058] It also includes a torsion spring mounting mechanism for positioning and installing the torsion spring 31 on the charging door 29. The torsion spring 31 is fitted on the outside of the positioning end, and the outer wall of the positioning end is provided with a spring retainer 302 for positioning one end of the torsion spring 31. The torsion spring mounting mechanism includes a lever 6 for moving the other end of the torsion spring 31 and a lever drive cylinder 7 for driving the lever 6. The lever 6 is rotatably mounted on the mounting platform 2, and the cylinder body of the lever drive cylinder 7 is mounted on the mounting platform 2.

[0059] The pin positioning and installation device also includes a platform lifting mechanism for lifting the fixed installation platform 2. The platform lifting mechanism includes a lifting drive cylinder 10, and the fixed installation platform 2 is connected to the frame 1 through the lifting drive cylinder 10. The installation of the charging door 29 can be achieved by moving the positioned charging door 29, that is, moving the positioned charging door 29 toward the pin 30 and torsion spring 31, or by moving the pin 30 and torsion spring 31, that is, moving the positioned pin 30 and torsion spring 31 toward the charging door 29. The fixed installation platform 2 is height-adjustable and is mounted on the frame 1. The fixed installation platform 2 is movable, so after the pin 30 and torsion spring 31 are positioned, the platform lifting mechanism is activated, and the fixed installation platform 2 can carry the pin 30 and torsion spring 31 upwards toward the positioned charging door 29, thereby realizing the automated installation of the pin 30 and torsion spring 31 of the charging door 29.

[0060] The cylinder body of the lifting drive cylinder 10 is connected to the frame 1, and the piston rod of the lifting drive cylinder 10 is connected to the mounting platform 2. The lifting drive cylinder 10 can be a servo electric cylinder. Servo electric cylinders have high control precision and accuracy, and using a servo electric cylinder as the press-fit power source improves the press-fit position accuracy of the charging gate 29.

[0061] It also includes a shaft seat drive cylinder 14 for adjusting the position of the shaft positioning seat 13. The shaft positioning seat 13 is mounted on the frame 1 via the shaft seat drive cylinder 14. The shaft positioning seat 13 is mounted on the frame 1 via the shaft seat drive cylinder 14. The piston rod of the shaft seat drive cylinder 14 is connected to the shaft positioning seat 13, or connected to the shaft positioning seat 13 via a shaft seat mounting plate. The position of the shaft positioning seat 13 can be adjusted via the shaft seat drive cylinder 14. Specifically, after the charging door 29 is pre-installed, the traction shaft passing through the shaft hole of the shaft positioning seat 13 can be manually inserted into the hinge hole 293 of the charging door 29. Then, the cover plate 292 of the charging door 29 is positioned, and the position of the shaft positioning seat 13 can be manually adjusted. Pressing down allows the shaft positioning seat 13 to move to the working position. The lower end face of the working position shaft positioning seat 13 can act on the upper end face of the hinge hole 293 of the positioned charging door 29. Then, the pin 30 and torsion spring 31 of the charging door 29 are installed. The shaft positioning seat 13 is manually pressed to the working position. The shaft positioning seat 13 can be reset from the working position to the original position by the shaft seat drive cylinder 14. Of course, the positional change between the original position and the working position of the shaft positioning seat 13 can also be adjusted by the shaft seat drive cylinder 14.

[0062] The shaft positioning seat 13 is connected to the frame 1 or the shaft driving cylinder 14 via a slide rail. The slide rail can be set on the frame 1 or the cylinder body of the shaft driving cylinder 14. The shaft positioning seat 13 has a slide groove or slider that matches the slide rail. The shaft positioning seat 13 can slide along the length of the slide rail, reducing the radial force on the shaft driving cylinder 14. The position of the shaft positioning seat 13 relative to the frame 1 can be guided, limited, and adjusted by the slide rail. To facilitate the positioning of the charging door 29, the original position of the shaft positioning seat 13 can be placed away from the charging door 29. This facilitates the installation and placement of the charging door 29. After the housing 291 of the charging door 29 is positioned, the guide shaft 12, which is inserted into the shaft hole of the shaft positioning seat, is inserted into the hinge hole 293 of the hinge part and the hinge hole 293 of the gooseneck to align the housing 291 and the cover plate 292 concentrically. After the housing 291 and the cover plate 292 of the charging door 29 are aligned, the cover plate 292 is... After positioning, the shaft positioning seat 13 can move towards the charging door 29. For example, the shaft positioning seat 13 can be manually pressed down, or the shaft seat drive cylinder 14 can be used to control the shaft positioning seat 13 to move down. The shaft positioning seat 13 is stably positioned by abutting the end face of the shaft positioning seat 13 against the end face of the hinge hole 293 of the charging door 29. The slide rail makes operation more convenient and effortless, and also accurately guides and positions the guide shaft 12 to ensure the pre-positioning effect of the guide shaft 12.

[0063] It also includes a pin constraint mechanism for constraining the pin 30 when it mates with the guide shaft 12. The pin constraint mechanism is located between the mounting platform 2 and the shaft positioning seat 13 and is mounted on the frame 1. During the actual assembly of the charging door 29, to ensure that the pin 30 can be accurately inserted into the hinge hole 293 of the charging door 29, a guide shaft 12 is pre-installed in the hinge hole 293 of the charging door 29. Thus, during the assembly of the pin 30, as long as the pin 30 is accurately positioned and aligned, as the pin 30 approaches the charging door 29, the free end 303 of the pin 30 will mate with the pre-installed guide shaft 12. Then, the guide shaft 12 is pushed out to complete the installation of the pin 30 of the charging door 29. Due to the mate process... The guide shaft 12 applies force to the free end 303 of the pin 30, which may affect the positioning stability of the pin 30. Therefore, a pin constraint mechanism is set up. When the pin 30 is connected to the guide shaft 12, the pin constraint mechanism can be activated. The free end 303 of the pin 30 can pass through the pin constraint mechanism. The pin constraint mechanism constrains and supports the pin rod part of the pin 30, which solves the problem of the pin 30's stability when it is connected to the guide shaft 12, thereby meeting the requirements of the pin 30's assembly stability and assembly quality.

[0064] The pin restraint mechanism includes a pair of restraint clamps 26 and a restraint cylinder 27 for driving the pair of restraint clamps 26 to clamp or release. When the pair of restraint clamps 26 clamp, they can form a restraint hole for the pin 30 to pass through. Specifically, the pin restraint mechanism can be a pair of restraint clamps 26. When the free end 303 of the pin 30 approaches the guide shaft 12, the restraint clamps 26, under the action of the restraint cylinder 27, can hold the pin and form a restraint hole for the pin 30 to pass through. As the free end 303 of the pin 30 passes through the restraint hole and then docks with the guide shaft 12, the restraint hole can restrain and support the pin 30. This ensures the stability and positioning accuracy of the pin 30 when docking with the guide shaft 12, and fully prepares the subsequent pin 30 to push the guide shaft 12 out and insert into the hinge hole 293 of the charging door 29.

[0065] It also includes an adjusting cylinder 28 for adjusting the position of the pin restraint mechanism. The restraint cylinder 27 of the pin restraint mechanism is connected to the frame 1 through the adjusting cylinder 28. The pin restraint mechanism must not only solve the problem of stable positioning when the pin 30 is docked, but also not hinder the assembly of the pin 30. Therefore, the position of the pin restraint mechanism is designed to be adjustable. When needed, the pin restraint mechanism can be moved to the working position, that is, the adjusting cylinder 28 can move the pin restraint mechanism to the working position. After the pin 30 is docked, the pin restraint mechanism can also be withdrawn from the working position in time under the action of the adjusting cylinder 28, and the pin 30 can continue to act until the guide shaft 12 is pushed out to complete the assembly of the pin 30.

[0066] The mounting platform 2 is also equipped with a pin detection sensor 8 for detecting whether the pin 30 on the support platform 3 is in place. When the pin detection sensor 8 detects the pin 30, the pin 30 is positioned correctly, and the pin detection sensor 8 transmits a signal to the control system.

As the pin 30 continues to rise, the position adjustment cylinder 24... Reset the pin constraint mechanism to avoid interfering with the continued installation of the pin 30. When the pin 30 moves to the position of compressing the torsion spring 31, the pin can stop moving. The drive cylinder 7 is activated, and the lever 6 acts on the other end of the torsion spring 31 to compress the torsion spring 31. Then the pin 30 continues to move upward until the pin 30 pushes the guide shaft 12 out and inserts it into place. The drive cylinder 7 is reset, and the other end of the torsion spring 31 springs open to the spring mounting groove 294 of the housing 291. The installation of the pin 30 and the torsion spring 31 of the charging door 29 is completed.

[0079] This utility model's guide shaft can concentrically pre-align the hinge holes of the pre-installed charging door, preparing for the automated installation of the pins positioned on the support platform.
