[0002] Automobiles 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 fitted on the hinge pin. 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 doesn't require precise positioning of the charging gate; the operator simply holds the gate, aligns the cover with the housing, and then installs the hinge pins and torsion springs. This manual method is labor-intensive and prone to inconsistent quality due to human error, sometimes resulting in improper assembly. Therefore, there is an urgent need for intelligent charging gate installation equipment. To achieve automated installation, the first issue to consider is the positioning of the charging gate; stable positioning is the foundation for automated installation. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a positioning device for assembling charging doors.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a positioning device for assembling a charging door, the charging door including a shell and a cover plate hinged to the shell, including a frame, a shell positioning mechanism and a plate positioning mechanism, the shell positioning mechanism being used to position the shell, and the plate positioning mechanism being used to position the cover plate;

[0007] The shell positioning mechanism includes a shell positioning groove for positioning the shell and a clamping positioning component for positioning the shell on the shell positioning groove. The shell positioning groove and the clamping positioning component are respectively disposed on the frame. The shape of the shell positioning groove is adapted to the shell.

The plate positioning mechanism includes one or more positioning suction cups for adsorbing the cover plate. The positioning suction cups are disposed on the frame.

[0008] The beneficial effects of this utility model are as follows: The housing of the charging door to be installed is placed into the housing positioning groove. The shape of the housing positioning groove matches the side of the housing away from the cover plate, enabling accurate positioning of the housing. The pressing and positioning component then presses the housing firmly into the positioning groove. After the housing is positioned, the cover plate can be positioned using the positioning suction cup of the plate positioning mechanism. Positioning via the suction cup is convenient and quick. This utility model has a simple structure, is easy and quick to operate, and provides accurate housing and convenient cover plate positioning, thus realizing the positioning of the charging door's housing and cover plate and preparing for the automated installation of the charging door's hinge pin and torsion spring.

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

[0010] Furthermore, the clamping and positioning assembly includes one or more pressure heads that can act on the housing and a pressure head driving mechanism for driving the pressure heads to move. Under the action of the pressure head driving mechanism, the pressure heads can move closer to the housing to clamp or move away from the housing to release it.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the housing of the charging door is placed into the housing positioning groove, and then the pressure head drive mechanism is activated to drive the pressure head to press against the housing, which can achieve the goal of pressing the housing tightly onto the housing positioning groove. When it is necessary to remove the housing, the pressure head drive mechanism is reset, which drives the pressure head away from the housing, and the pressure head releases the housing, so that the housing can be removed from the housing positioning groove, waiting for the positioning of the housing of the next charging door.

[0012] Furthermore, the pressure head driving mechanism includes a driving arm, a driving link, and a pressure head driving cylinder. The pressure head driving cylinder is mounted on the frame. The piston rod of the pressure head driving cylinder is hinged to one end of the driving arm, and the other end of the driving arm is connected to the pressure head. One end of the driving link is hinged to the middle of the driving arm, and the other end is hinged to the frame.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the piston rod of the pressure head drive cylinder retracts, driving the pressure head away from the housing. At this time, it can be used to place the housing to be installed or to remove the housing that has been installed. The piston rod of the pressure head drive cylinder extends, and under the cooperation of the drive arm and the drive connecting rod, the pressure head presses the housing onto the housing positioning groove, which can realize the housing positioning of the charging door.

[0014] Furthermore, the pressure head drive mechanism is located on the side of the shell positioning groove away from the plate positioning mechanism.

[0015] The beneficial effect of adopting the above-mentioned further solution is that a cover plate is hinged to one side of the housing, and the plate positioning mechanism can position the cover plate and also play a certain positioning role on this side of the housing. Therefore, the pressure head driving mechanism can be set on the opposite side of the housing to achieve stable positioning of the housing.

[0016] Furthermore, the housing has a shell hole in the middle, and the shell positioning groove has a slot corresponding to the shell hole. It also includes an auxiliary positioning mechanism for positioning the housing. The auxiliary positioning mechanism performs auxiliary positioning of the housing by acting on the hole wall of the shell hole.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, for the positioning of the charging door housing, there is not only a housing positioning mechanism that can act on the periphery of the housing, but also an auxiliary positioning mechanism that can extend from the housing hole into the housing and act on the hole wall of the housing hole. Through internal and external positioning, the positioning stability and reliability of the charging door housing are further improved.

[0018] Furthermore, the auxiliary positioning mechanism includes an auxiliary pressure block and an auxiliary drive mechanism for driving the extension and retraction of the auxiliary pressure block. The auxiliary drive mechanism is mounted on the frame via a position adjustment cylinder.

[0019] The beneficial effect of adopting the above-mentioned further solution is that after the housing is placed in the housing positioning groove, the position adjustment cylinder is activated, the auxiliary positioning mechanism moves towards the housing of the charging door, the auxiliary drive mechanism is activated, and the auxiliary pressure block can extend and act on the housing hole wall. The outer periphery of the housing is pressed and positioned by the pressure head of the housing positioning mechanism, and the inner periphery of the housing is pressed and positioned by the auxiliary pressure block, which further ensures the positioning stability and reliability of the housing.

[0020] Furthermore, the auxiliary drive mechanism includes an auxiliary housing and an auxiliary connecting rod movably disposed on the auxiliary housing. The auxiliary housing has a pressure block channel for sliding the auxiliary pressure block and a cavity for moving the auxiliary connecting rod. One end of the auxiliary connecting rod is hinged to the piston rod of the position adjustment cylinder, and the other end is hinged to the inner end of the auxiliary pressure block. The outer end of the auxiliary pressure block can extend out of the auxiliary housing and act on the hole wall of the housing hole.

[0021] The beneficial effect of adopting the above-mentioned further solution is that when the piston rod of the position adjustment cylinder extends, it pushes one end of the auxiliary connecting rod towards the auxiliary housing, and the outer end of the auxiliary pressure block can extend out of the pressure block channel. The auxiliary pressure block can act on the hole wall of the housing to achieve positioning of the housing. When the piston rod of the position adjustment cylinder retracts, it pulls one end of the auxiliary connecting rod towards the position adjustment cylinder side, and the outer end of the auxiliary pressure block can retract into the pressure block channel. The auxiliary pressure block moves away from the hole wall of the housing, and the auxiliary positioning mechanism resets, without interfering with the picking and putting of the housing.

[0022] Furthermore, the auxiliary drive mechanism employs an auxiliary pressure cylinder, the auxiliary pressure block is connected to the drive end of the auxiliary pressure cylinder, and the cylinder body of the auxiliary pressure cylinder is connected to the piston rod of the position adjustment cylinder.

[0023] The beneficial effect of adopting the above-mentioned further solution is that when the piston rod of the position adjustment cylinder extends, the auxiliary pressure cylinder moves towards the housing, the auxiliary pressure cylinder moves, and the auxiliary pressure block extends and acts on the hole wall of the housing to position the housing. In specific implementation, the extension distance of the position adjustment cylinder can be larger, so that after the auxiliary pressure block extends, the piston rod of the position adjustment cylinder retracts a certain distance, so that the auxiliary pressure block can press firmly on the hole wall of the housing, meeting the positioning stability and reliability requirements of the charging door housing.

[0024] Furthermore, the frame is also provided with a suction cup adjustment cylinder for adjusting the position of the positioning suction cup; the piston rod of the suction cup adjustment cylinder is connected to the positioning suction cup, or the piston rod of the suction cup adjustment cylinder is connected to a mounting plate for mounting the positioning suction cup.

[0041] 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.

[0042] Example 1, such as Figures 1-10As shown, a positioning device for assembling a charging door is provided. The charging door includes a housing 15 and a cover plate 16 hinged to the housing 15. The device includes a frame 1, a housing positioning mechanism, and a plate positioning mechanism. The housing positioning mechanism is used to position the housing 15 of the charging door, and the plate positioning mechanism is used to position the cover plate 16 of the charging door.

[0043] The shell positioning mechanism includes a shell positioning groove 2 for positioning the shell 15 and a clamping positioning component for positioning the shell 15 on the shell positioning groove 2. The shell positioning groove 2 and the clamping positioning component are respectively disposed on the frame 1. The shape of the shell positioning groove 2 is adapted to the shell 15. The clamping positioning component can clamp and position the shell 15 placed in the shell positioning groove 2. The plate positioning mechanism includes one or more positioning suction cups 3 for adsorbing the cover plate 16. The positioning suction cups 3 are disposed on the frame 1. The cover plate 16 can be positioned under the adsorption force of the positioning suction cups 3, which is convenient and quick, and facilitates the positioning and placement of the cover plate 16 of the charging door.

[0044] The clamping and positioning assembly includes one or more pressure heads 4 that can act on the housing 15 and a pressure head driving mechanism for driving the pressure heads 4. Under the action of the pressure head driving mechanism, the pressure heads 4 can move closer to and clamp the housing 15 or move away from and release the housing 15. The housing 15 of the charging door is placed into the housing positioning groove 2, and then the pressure head driving mechanism is activated, driving the pressure heads 4 to press against the housing 15, thus clamping the housing 15 onto the housing positioning groove 2. When it is necessary to remove the housing 15, the pressure head driving mechanism resets, driving the pressure heads 4 away from the housing 15, and the pressure heads 4 release the housing 15, so that the housing 15 can be removed from the housing positioning groove 2, waiting for the positioning of the housing 15 of the next charging door.

[0045] The pressure head driving mechanism includes a driving arm 5, a driving link 6, and a pressure head driving cylinder 7. The pressure head driving cylinder 7 is mounted on the frame 1. The piston rod of the pressure head driving cylinder 7 is hinged to one end of the driving arm 5, and the other end of the driving arm 5 is connected to the pressure head 4. One end of the driving link 6 is hinged to the middle of the driving arm 5, and the other end is hinged to the frame 1. When the piston rod of the pressure head driving cylinder 7 retracts, it drives the pressure head 4 away from the housing 15. At this time, it can be used to place the housing 15 to be installed or to remove the housing 15 that has been installed. When the piston rod of the pressure head driving cylinder 7 extends, under the combined action of the driving arm 5 and the driving link 6, the pressure head 4 presses the housing 15 tightly onto the housing positioning groove 2, thereby achieving the positioning of the housing 15 of the charging door.

[0046] The pressure head driving mechanism is located on the side of the housing positioning groove 2 away from the plate positioning mechanism. A cover plate 16 is hinged to one side of the housing 15. The plate positioning mechanism can position the cover plate 16 and also play a certain positioning role on this side of the housing 15. Therefore, the pressure head driving mechanism can be located on the opposite side of the housing 15 to achieve stable positioning of the housing 15.

[0047] The shell positioning groove 2 is provided with a plurality of positioning posts for positioning the shell 15.

[0048] The housing 15 has a housing hole in its middle, and the housing positioning groove 2 has a corresponding slot. It also includes an auxiliary positioning mechanism for positioning the housing 15. This auxiliary positioning mechanism assists in positioning the housing 15 by acting on the wall of the housing hole. For the positioning of the charging door housing 15, in addition to the housing positioning mechanism acting on the periphery of the housing 15, an auxiliary positioning mechanism is also provided that extends from inside the housing hole into the housing 15 and acts on the wall of the housing hole. Through internal and external positioning, the positioning stability and reliability of the charging door housing 15 are further improved. The auxiliary positioning mechanism is disposed on the frame 1 or the housing positioning groove 2.

[0049] The auxiliary positioning mechanism includes an auxiliary pressure block 8 and an auxiliary drive mechanism 9 for driving the extension and retraction of the auxiliary pressure block 8. The auxiliary drive mechanism 9 is mounted on the frame 1 via a position adjustment cylinder 10. After the housing is placed in the housing positioning groove, the position adjustment cylinder 10 is activated, the auxiliary positioning mechanism moves towards the housing of the charging door, the auxiliary drive mechanism is activated, and the auxiliary pressure block 8 extends and acts on the wall of the housing hole. The outer periphery of the housing is pressed and positioned by the pressure head of the housing positioning mechanism, while the inner periphery of the housing is pressed and positioned by the auxiliary pressure block of the auxiliary positioning mechanism, further ensuring the positioning stability and reliability of the housing. An auxiliary pad can also be provided on the working surface of the auxiliary pressure block. The auxiliary pad can be made of materials such as nylon to avoid damaging the housing.

[0050] The auxiliary drive mechanism 9 includes an auxiliary housing 91 and an auxiliary connecting rod 92 movably mounted on the auxiliary housing. The auxiliary housing 91 contains a pressure block channel 911 for sliding the auxiliary pressure block and a cavity 912 for the auxiliary connecting rod to move. One end of the auxiliary connecting rod 92 is hinged to the piston rod of the position adjustment cylinder 10, and the other end is hinged to the inner end of the auxiliary pressure block 8. The outer end of the auxiliary pressure block 8 can extend out of the auxiliary housing 91 and act on the wall of the housing hole. When the piston rod of the position adjustment cylinder extends, it pushes one end of the auxiliary connecting rod towards the auxiliary housing, allowing the outer end of the auxiliary pressure block to extend out of the pressure block channel and act on the wall of the housing hole, thus positioning the housing. When the piston rod of the position adjustment cylinder retracts, it pulls one end of the auxiliary connecting rod towards the position adjustment cylinder side, allowing the outer end of the auxiliary pressure block to retract into the pressure block channel, moving the auxiliary pressure block away from the wall of the housing hole. The auxiliary positioning mechanism resets, without interfering with the placement or removal of the housing.

[0051] One or two auxiliary pressure blocks 8 can be provided. When two are provided, two auxiliary connecting rods 92 are provided accordingly. The two auxiliary pressure blocks 8 are respectively hinged to the position adjustment cylinder 10 through the auxiliary connecting rods 92. Under the action of the position adjustment cylinder, the two pressure blocks can act on the upper and lower or left and right walls of the shell hole, ensuring the positioning stability of the shell.

[0052] The frame 1 is also equipped with a suction cup adjustment cylinder 11 for adjusting the position of the positioning suction cup 3; the piston rod of the suction cup adjustment cylinder 11 is connected to the positioning suction cup 3, or the piston rod of the suction cup adjustment cylinder 11 is connected to a mounting plate for mounting the positioning suction cup 3. The suction cup adjustment cylinder 11 can adjust the position of the positioning suction cup 3 to meet the requirements of the positioning suction cup 3 as needed, such as the adjusted positioning suction cup 3 being able to stably and accurately adsorb the cover plate 16 of the charging door.

[0053] The positioning suction cup 3 is a vacuum suction cup. It forms a vacuum by adsorbing air, resulting in strong adsorption force, good stability, and resistance to loosening. It does not affect the surface integrity of the charging door cover 16, and the adsorption and release of the cover 16 are convenient and quick.

[0054] It also includes a plate detection sensor 12 for detecting whether the cover plate 16 of the charging door is positioned correctly, and the plate detection sensor 12 is mounted on the frame 1. The plate detection sensor 12 can detect the cover plate 16 of the charging door to ensure that the cover plate 16 of the charging door is installed and positioned correctly, so as to facilitate the control system to perform subsequent installation actions of the charging door.

[0055] In Example 2, the auxiliary drive mechanism 9 employs an auxiliary pressure cylinder. The auxiliary pressure block 8 is connected to the drive end of the auxiliary pressure cylinder, and the cylinder body of the auxiliary pressure cylinder is connected to the piston rod of the position adjustment cylinder 10. When the piston rod of the position adjustment cylinder 10 extends, the auxiliary pressure cylinder moves towards the housing, causing the auxiliary pressure cylinder to actuate. The auxiliary pressure block 8 extends and acts on the hole wall of the housing to position it. In specific implementations, the extension distance of the position adjustment cylinder can be larger, so that after the auxiliary pressure block 8 extends, the piston rod of the position adjustment cylinder 10 retracts a certain distance, allowing the auxiliary pressure block 8 to press firmly against the hole wall of the housing, meeting the positioning stability and reliability requirements of the charging door housing. There can be one or two auxiliary pressure blocks 8. If there are two, a double-headed drive cylinder can be used. The remaining structure is the same as in Example 1, and therefore will not be described again here.

[0056] The charging door housing 15 and cover plate 16 are pre-assembled, that is, the gooseneck of the cover plate 16 is placed into the hinge part of the housing 15. Then, the charging door housing 15 is placed into the housing positioning groove 2. The shape of the housing positioning groove 2 is adapted to the side of the housing 15 away from the cover plate 16 to accurately position the housing 15. The pressing positioning component is activated, and the pressing head 4 can press against the edge of the housing 15 to press the housing 15 into the housing positioning groove 2. The position adjustment cylinder 10 is activated, and the auxiliary pressing cylinder 9 extends into the housing hole. The auxiliary pressing block 8 can extend from the housing hole and act on the hole wall of the housing 15 to press the hole wall of the housing 15 into the housing positioning groove 2. After the housing 15 is positioned, there is a concentric pre-positioning mechanism on the frame 1. The concentric pre-positioning mechanism includes a shaft positioning seat 13 and a guide shaft 14. 3 has shaft holes corresponding to the installation positions of the hinge pins of the charging door. The guide shaft 14, which is inserted into the shaft hole, can be manually inserted into the hinge hole 17 of the hinge part of the housing 15 and the hinge hole 17 of the gooseneck of the cover plate 16. The manual insertion can be adjusted in real time by hand according to the alignment of the hinge hole 17 of the hinge part and the hinge hole 17 of the gooseneck to ensure that the guide shaft 14 is inserted in place and to avoid damage to the guide shaft 14 and the charging door. After the hinge hole 17 of the charging door is concentrically aligned, the cover plate 16 can be positioned. Rotate the cover plate 16 close to the positioning suction cup 3. The positioning suction cup 3 can attract and position the cover plate 16 of the charging door, thereby realizing the accurate positioning of the housing 15 and the cover plate 16 of the charging door, and preparing for the automated installation of the hinge pin and torsion spring of the charging door.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
