Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to an assist device and a charging pile. Background Technology

[0002] Currently, charging piles on the market use assistive devices to extend and retract the charging cable, but existing assistive devices require an additional power structure, which takes up a lot of space.

[0003] Therefore, how to reduce the size of the assist device has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This application proposes an assist device and a charging station to reduce the size of the assist device.

[0005] To achieve the above objectives, this application discloses the following technical solutions:

[0006] In a first aspect, this application provides an assistive device, including a fixed base, a swing arm mechanism, and a reset hinge;

[0007] The reset hinge includes a hinge assembly and an energy storage assembly that are connected by transmission. The hinge assembly is fixedly connected to one of the fixed base and the swing arm mechanism so that the swing arm mechanism is rotatably connected to the fixed base, and the swing arm mechanism has a folded state and an unfolded state. The energy storage assembly is fixedly connected to the other of the fixed base and the swing arm mechanism, and the energy storage assembly has an energy storage state and an energy release state.

[0008] Specifically, when an external force is applied to the swing arm mechanism, the swing arm mechanism switches from a folded state to an unfolded state, and the energy storage component switches from an energy release state to an energy storage state; when the external force is removed from the swing arm mechanism, the energy storage component switches from an energy storage state to an energy release state, so that the swing arm mechanism switches from an unfolded state to a folded state.

[0009] In some embodiments, the hinge assembly includes a hinge pivot and a first hinge, the first hinge being fixedly connected to the hinge pivot, wherein the hinge assembly is fixedly connected to the swing arm mechanism via the first hinge.

[0010] In some embodiments, the first hinge is fixed to the hinge shaft by a first fastener; the hinge assembly also includes a retaining sleeve fitted onto the hinge shaft, and the first fastener passes through the circumferential surface of the retaining sleeve and is connected to the hinge shaft.

[0011] In some embodiments, the energy storage assembly includes a support member, a second hinge, an energy storage shaft, a torsion spring, and a fixing member;

[0012] The second hinge is used to connect to the fixed base; the energy storage shaft and the fixing member are respectively set at both ends of the support member, wherein the energy storage shaft is rotatable relative to the support member; the first end of the torsion spring is connected to the energy storage shaft, and the second end of the torsion spring is connected to the fixing member; the hinge shaft is rotatably set on the support member.

[0013] In some embodiments, the fastener is connected to the support via a second fastener; and / or

[0014] The second hinge and the support are integrated into one structure.

[0015] In some embodiments, a bearing is also provided between the hinge pivot and the support member.

[0016] In some embodiments, the hinge assembly and the energy storage assembly are connected by a transmission assembly, which includes a first gear and a second gear. The first gear is arranged coaxially with the hinge shaft and can rotate with the hinge shaft. The second gear is arranged coaxially with the energy storage shaft and meshes with the first gear.

[0017] In some embodiments, the transmission assembly further includes a partition, a sealing cover, and a protective cover, wherein the partition is located between the support and the first gear, the sealing cover is fitted around the outer periphery of the first gear and the second gear, and the protective cover is fitted around the outer periphery of the sealing cover.

[0018] In some embodiments, the swing arm mechanism is provided with a wire clamp for securing the charging gun cable.

[0019] Secondly, this application provides a charging pile, including a main unit, a charging gun cable, and an assist device as described above, wherein the swing arm mechanism of the assist device is connected to the charging gun cable; the assist device is located on top of the main unit.

[0020] As can be seen from the above technical solution, taking the application of the above-mentioned assistive device to a charging pile as an example, the assistive device is connected to the charging pile, and the charging gun cable is connected to the swing arm mechanism, so that the charging gun cable is suspended at a high position of the charging pile. When charging is needed, the charging gun cable is moved, and the charging gun cable applies an external force to the swing arm mechanism, causing the swing arm mechanism to move from a folded state to an unfolded state. At the same time, the energy storage component stores energy to meet the space requirements required for the charging gun cable to charge. When charging is complete, the charging gun cable is moved, the external force acting on the swing arm mechanism is removed, the energy storage component switches from an energy storage state to an energy release state, and drives the swing arm mechanism to switch from an unfolded state to a folded state to store the charging gun cable. The above-mentioned assistive device of this application can assist the charging gun cable in moving during the charging process without dragging the charging gun cable. Therefore, it can reduce the occurrence of phenomena such as wear, aging, leakage, and even damage to the charging gun cable caused by friction between the charging gun cable and the ground. It improves the user experience, the overall reliability of the charging pile, extends the service life, reduces maintenance costs, and reduces safety hazards. As can be seen, since the reset hinge in the assist device of this application includes a hinge assembly and an energy storage assembly, the reset of the swing arm mechanism can be achieved without setting an additional power structure, thus reducing the size of the assist device.

[0044] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0045] To achieve the above objectives, this application discloses the following technical solutions:

[0046] See Figure 1 and Figure 2 , Figure 1 A perspective view of the assist device 10 in a folded state has been released; Figure 2 A perspective view of the assist device 10 in its deployed state has been released.

[0047] The assist device 10 may include a fixed base 11, a swing arm mechanism 12, and a reset hinge 13. The reset hinge 13 includes a hinge assembly 131 and an energy storage assembly 132 that are connected by a transmission. The hinge assembly 131 is fixedly connected to one of the fixed base 11 and the swing arm mechanism 12, so that the swing arm mechanism 12 is rotatably connected to the fixed base 11, and the swing arm mechanism 12 has a folded state and an unfolded state. The energy storage assembly 132 is fixedly connected to the other of the fixed base 11 and the swing arm mechanism 12, and the energy storage assembly 132 has an energy storage state and an energy release state. When an external force is applied to the swing arm mechanism 12, the swing arm mechanism 12 is able to... Figure 1 The folded state shown is switched to Figure 2In the deployed state shown, the energy storage component 132 switches from the energy release state to the energy storage state; when the external force removes the swing arm mechanism 12, the energy storage component 132 switches from the energy storage state to the energy release state, so that the swing arm mechanism 12 changes from the energy storage state to the energy release state. Figure 2 The unfolded state shown is switched to Figure 1 The folded state shown.

[0048] Taking the aforementioned assist device 10 applied to a charging pile as an example, the assist device 10 is connected to the charging pile, and the charging gun cable 30 is connected to the swing arm mechanism 12, so that the charging gun cable 30 is suspended at a high position on the charging pile. When charging is required, the charging gun cable 30 is moved, and the charging gun cable 30 applies an external force to the swing arm mechanism 12, causing the swing arm mechanism 12 to move from a folded state to an unfolded state. At the same time, the energy storage component 132 stores energy to meet the space requirements required for the charging gun cable 30 to charge. When charging is complete, the charging gun cable 30 is moved, the external force acting on the swing arm mechanism 12 is removed, the energy storage component 132 switches from an energy storage state to an energy release state, and drives the swing arm mechanism 12 to switch from an unfolded state to a folded state to store the charging gun cable 30. The assist device 10 described in this application can assist the charging cable 30 in moving during charging without dragging it. Therefore, it reduces wear, aging, leakage, and even damage from being run over by wheels caused by friction between the charging cable 30 and the ground. This improves user experience, overall reliability, extends service life, reduces maintenance costs, and minimizes safety hazards. Furthermore, since the reset hinge 13 in the assist device includes a hinge assembly 131 and an energy storage assembly 132, the reset of the swing arm mechanism 12 can be achieved without an additional power structure, thus reducing the size of the assist device 10.

[0049] It should be noted that, as mentioned above, one fixed base 11 corresponds to the installation of two swing arm mechanisms 12. In some examples of this application, one fixed base 11 may correspond to the installation of one swing arm mechanism 12; or in some examples, one fixed base 11 may correspond to the installation of three, four, five, or more swing arm mechanisms 12. The number of swing arm mechanisms 12 is related to the number of charging gun cables 30 on the charging pile.

[0050] The aforementioned swing arm mechanism 12 includes at least two swing arms, which are rotatably connected. The swing arm at the end is connected to the fixed base 11 via a reset hinge 13. As shown in the figure, the swing arm mechanism 12 includes two swing arms, namely a first swing arm 121 and a second swing arm 122. The first swing arm 121 is located at the beginning of the swing arm mechanism 12, and the second swing arm 122 is located at the end of the swing arm mechanism 12. Of course, in some examples of this application, the number of swing arms in the swing arm mechanism 12 is not limited to two and can be adjusted according to requirements. The end of the swing arm mechanism 12 connected to the fixed base 11 is defined as the beginning end, and the end corresponding to the beginning end is the end end.

[0051] To facilitate the installation of the charging gun cable 30, in some examples of this application, the assist device 10 may also include a lifting ring 14 and a cable clamp 15. The lifting ring 14 is fixed to the end of the swing arm mechanism 12, the cable clamp 15 is fixed to the lifting ring 14, and the charging gun cable 30 is fixedly connected inside the cable clamp 15.

[0052] To accommodate the use of charging gun cables 30 at different angles, the lifting ring 14 is connected to the swing arm mechanism 12, which is rotatable about its own axis.

[0053] See Figures 3 to 5 In this application, the hinge assembly 131 has two functions: first, to enable the swing arm mechanism 12 to be rotatably connected to the fixed seat 11; and second, to enable the swing arm mechanism 12 to be reset (moving from the unfolded state to the folded state). Specifically, the hinge assembly 131 enables the swing arm mechanism 12 to be rotatably connected to the fixed seat 11, and the energy storage assembly 132 enables the swing arm mechanism 12 to be reset.

[0054] In some examples, the rotation axis of hinge assembly 131 is parallel to the rotation axis of energy storage assembly 132; in other examples, the rotation axis of hinge assembly 131 intersects the rotation axis of energy storage assembly 132. Using parallel rotation axes reduces the radial dimension of the reset hinge 13.

[0055] As described above, one of the hinge assembly 131 and the energy storage assembly 132 is connected to the swing arm mechanism 12, and the other of the hinge assembly 131 and the energy storage assembly 132 is connected to the fixed base 11. In the following examples, this application will only describe the connection between the hinge assembly 131 and the swing arm mechanism 12, and the connection between the energy storage assembly 132 and the fixed base 11. The connection between the hinge assembly 131 and the fixed base 11, and the connection between the energy storage assembly 132 and the swing arm mechanism 12, is simply a matter of swapping the installation positions of the fixed base 11 and the swing arm mechanism 12 with the reset hinge 13. Please refer to the following description.

[0056] See Figures 6 to 8 The hinge assembly 131 in this application example includes a hinge pivot 1311 and a first hinge 1312, wherein the first hinge 1312 is fixedly connected to the hinge pivot 1311, and the hinge assembly 131 is fixedly connected to the swing arm mechanism 12 via the first hinge 1312. The first hinge 1312 has a first mounting hole 1312b, through which the first hinge 1312 is mounted on the swing arm mechanism 12; the second hinge 1322 has a second mounting hole 1322a, through which the second hinge 1322 is mounted on the fixed base 11.

[0057] The first hinge 1312 and the hinge pin 1311 can be detachably or non-detachably connected. A detachable connection allows for the removal of both the first hinge 1312 and the hinge pin 1311, for example, using fasteners or threaded connections. With a detachable connection, if either the first hinge 1312 or the hinge pin 1311 is damaged, it can be replaced individually, facilitating maintenance and reducing operating costs. A non-detachable connection means that the first hinge 1312 and the hinge pin 1311 are a single, integrated structure, or they are connected by welding, reducing assembly steps and improving assembly efficiency.

[0058] In one embodiment, the first hinge 1312 and the hinge shaft 1311 are detachably connected. The first hinge 1312 is fixed to the hinge shaft 1311 by a first fastener 1314. A first hole 1312a is provided on the part of the first hinge 1312 opposite to the hinge shaft 1311, and a second hole 1321a is provided on the hinge shaft 1311. The first fastener 1314 is threaded to the first hole 1312a and the second hole 1321a to realize the connection between the first hinge 1312 and the hinge shaft 1311. The first hole 1312a and the second hole 1321a constitute a group. Two groups are provided in the figure to improve the stress stability and connection strength during the connection process between the first hinge 1312 and the hinge shaft 1311.

[0059] To improve the connection strength between the first hinge 1312 and the hinge shaft 1311, the hinge assembly 131 may further include a fixed sleeve 1313, which is sleeved on the hinge shaft 1311. The first fastener 1314 passes through the fixed sleeve 1313 from the circumference of the fixed sleeve 1313 and is connected to the hinge shaft 1311.

[0060] The first hinge 1312 and the fixed sleeve 1313 can be detachably or non-detachably connected. In the non-detachable connection, the first hinge 1312 and the fixed sleeve 1313 are an integral structure, or they are connected by welding. In this case, the first hinge 1312 has a first hole 1312a, and the hinge shaft 1311 has a second hole 1321a. The first hole 1312a and the second hole 1321a are aligned. The first fastener 1314 sequentially engages with the first hole 1312a and the second hole 1321a to achieve a detachable connection between the first hinge 1312, the fixed sleeve 1313, and the hinge shaft 1311. Figure 7 and 8 As shown.

[0061] In the detachable connection between the first hinge 1312 and the fixed sleeve 1313, the outer periphery of the fixed sleeve 1313 is provided with a third hole. During installation, the first hole 1312a, the third hole and the second hole 1321a are aligned, and the first fastener 1314 cooperates with the first hole 1312a, the third hole and the second hole 1321a in sequence to realize the detachable connection between the first hinge 1312, the fixed sleeve 1313 and the hinge shaft 1311.

[0062] Since the reset hinge 13 is exposed, in order to reduce the entry of dust and other particulate matter into the hinge shaft 1311, sealing gaskets 1317 are also provided at both ends of the fixed sleeve 1313. By providing sealing gaskets 1317, the area between the hinge shaft 1311 and both ends of the fixed sleeve 1313 can be sealed, reducing the entry of dust and other particulate matter into the rotation area of ​​the hinge shaft 1311, reducing the wear of the hinge shaft 1311, and extending the service life of the assist device 10.

[0063] Furthermore, in some examples of this application, in order to reduce the friction during the rotation of the hinge shaft 1311 and improve the rotational smoothness of the hinge shaft 1311, bearings 1315 are provided at both ends of the hinge shaft 1311. The inner ring of the bearing 1315 is fixed to the outer circumference of the hinge shaft 1311, and the outer ring of the bearing 1315 is fixed to the support member 1321 described later.

[0064] In order to extend the service life of bearing 1315, a positioning sleeve 1316 is also provided on the outside of bearing 1315. By providing the positioning sleeve 1316, dust particles can be reduced from entering the bearing 1315, thereby extending the service life of bearing 1315.

[0065] The above focuses on the specific structure of the hinge assembly 131. The structure of the energy storage assembly 132 will be described in detail later.

[0066] Combination Figure 8 See Figures 9 to 10 The energy storage assembly 132 includes a support member 1321, a second hinge 1322, an energy storage shaft 1323, a torsion spring 1324, and a fixing member 1325. The second hinge 1322 is fixed to the outer periphery of the support member 1321 for connection with the fixing seat 11. The energy storage shaft 1323 and the fixing member 1325 are disposed at both ends of the support member 1321, and the energy storage shaft 1323 is rotatable relative to the support member 1321. The first end of the torsion spring 1324 is connected to the energy storage shaft 1323, and the second end of the torsion spring 1324 is connected to the fixing member 1325 to restrict the rotation of the second end of the torsion spring 1324. The hinge shaft 1311 is rotatably disposed on the support member 1321 about its own axis.

[0067] The first hinge 1312 and the second hinge 1322 are configured to be in a closed state and an open state. In the closed state, the angle between the surface of the first hinge 1312 and the surface of the second hinge 1322 is 90° or close to 90°, corresponding to the folded state of the swing arm mechanism 12. In the open state, the angle between the surface of the first hinge 1312 and the surface of the second hinge 1322 is 180° or close to 180°, corresponding to the unfolded state of the swing arm mechanism 12. An external force drives the hinge shaft 1311 to rotate, and the rotational motion of the hinge shaft 1311 is transmitted to the energy storage shaft 1323, causing the energy storage shaft 1323 to rotate. Since the two ends of the torsion spring 1324 are fixed, the first end of the torsion spring 1324 rotates to store energy during the rotation of the energy storage shaft 1323, and the first hinge 1312 and the second hinge 1322 switch from the closed state to the open state. After the external force is removed, the first end of the torsion spring 1324 rotates in the opposite direction, driving the energy storage shaft 1323 to rotate, which in turn drives the hinge shaft 1311 to rotate, so as to realize the reset of the entire reset hinge 13, and the first hinge 1312 and the second hinge 1322 switch from the open state to the closed state.

[0068] It should be noted that the aforementioned support member 1321 forms a support structure for the reset hinge 13, and both the hinge pivot 1311 and the energy storage pivot 1323 are rotatably disposed relative to the support member 1321. The fixing member 1325 and the second hinge 1322 are fixed relative to the support member 1321, wherein the fixing member 1325 is detachably or non-detachably connected to the support member 1321; and / or the second hinge 1322 is detachably or non-detachably connected to the support member 1321.

[0069] In addition, considering that the first hinge 1312 and the second hinge 1322 are in the closed state when no external force is applied, the energy storage assembly 132 may also include a locking element for easy installation and transportation. Therefore, the energy storage shaft 1323 is constructed in a locked state and a free state. When the energy storage shaft 1323 is in the locked state, the locking element fixes the energy storage shaft 1323 to the support member 1321, and at this time the first hinge 1312 and the second hinge 1322 are in the open state. When the energy storage shaft 1323 is in the free state, the energy storage shaft 1323 rotates relative to the support member 1321, and the entire reset hinge 13 can work normally.

[0070] In one embodiment of the locking component, the support member 1321 is provided with a first locking hole, and the energy storage shaft 1323 is provided with a second locking hole. The locking component can pass through the first locking hole and the second locking hole in sequence to lock the energy storage shaft 1323 to the support member 1321.

[0071] The support member 1321 of this application includes a first support portion 1321a, a second support portion 1321c, and a third support portion 1321d. The second support portion 1321c and the third support portion 1321d extend axially along the hinge shaft 1311 and form a notch 1323e between them to accommodate the first hinge 1312. They are arranged side by side with the first support portion 1321a. The first support portion 1321a is provided with a first cavity 1321b for installing the energy storage shaft 1323, the torsion spring 1324, and the fixing member 1325. The second hinge 1322 is provided on the outer periphery of the first support portion 1321a. The second support portion 1321c and the third support portion 1321d are provided with second cavities for installing the hinge shaft 1311. During assembly, the energy storage shaft 1323, torsion spring 1324, and fixing member 1325 are inserted into the first cavity 1321b, and the fixing member 1325 is fixedly connected to the first support part 1321a by the second fastener 1326; the first hinge 1312 is placed at the notch 1323e, the hinge shaft 1311 is inserted into the second support part 1321c, the first hinge 1312, and the third support part 1321d, and then the bearing 1315 is installed between the hinge shaft 1311 and the second cavity, as follows. Figure 8 and Figure 10 As shown.

[0072] The two ends of the torsion spring 1324 are respectively positioned between the hinge shaft 1311 and the fixing member 1325. The first end of the torsion spring 1324 can be fixedly connected to the energy storage shaft 1323, and the second end of the torsion spring 1324 can be fixedly connected to the fixing member 1325.

[0073] Specifically, the energy storage shaft 1323 includes a transmission part 1323b, a shaft body 1323a, and a first locking part 1323c connected in sequence. The transmission part 1323b is used to directly or indirectly engage with the hinge shaft 1311 for transmission, and the first locking part 1323c is used to engage with the first end of the torsion spring 1324.

[0074] The torsion spring 1324 is installed in a compressed state between the energy storage shaft 1323 and the fixing member 1325. The first locking part 1323c has a first locking slot. The first end of the torsion spring 1324 extends into the first locking slot to drive the first end of the torsion spring 1324 to rotate with the energy storage shaft 1323.

[0075] The fixing member 1325 includes a fixing body 1325a and a second locking part 1325b connected in sequence. The second locking part 1325b is used to cooperate with the second end of the torsion spring 1324. The second locking part 1325b has a second latch, and the second end of the torsion spring 1324 extends into the second latch to restrict the second end of the torsion spring 1324 from rotating with the energy storage shaft 1323.

[0076] To facilitate the installation of the energy storage shaft 1323, the fixing member 1325 is detachably installed on the support member 1321. The fixing member 1325 is connected to the support member 1321 via a second fastener 1326. Specifically, the outer periphery of the first support portion 1321a is provided with a fourth hole 1321f, and the outer periphery of the fixing member 1325 is provided with a fifth hole 1325c. The second fastener 1326 engages sequentially with the fourth hole 1321f and the fifth hole 1325c to achieve the detachable installation of the fixing member 1325 on the support member 1321.

[0077] In some examples of this application, sealing rings 1327 are provided at the parts where the energy storage shaft 1323 mates with the support member 1321 and at the parts where the fixing member 1325 mates with the support member 1321, in order to reduce the entry of dust and other particulate matter into the first cavity 1321b and extend the service life of the reset hinge 13.

[0078] To shorten the assembly time of the second hinge 1322 and the support member 1321, the second hinge 1322 and the support member 1321 are an integral structure, such as... Figure 9 and 10 As shown.

[0079] The rotation axis of the energy storage component 132 can be understood as the rotation axis of the energy storage shaft 1323, and the rotation axis of the hinge component 131 can be understood as the rotation axis of the hinge shaft 1311. That is, the rotation axis of the energy storage shaft 1323 and the rotation axis of the hinge shaft 1311 can be arranged parallel to each other or cross each other.

[0080] Combination Figure 5 and Figure 6 See Figure 11 and Figure 12 There are various ways to achieve the transmission connection between the hinge assembly 131 and the energy storage assembly 132, such as gear rotation and belt drive. Taking gear drive as an example, the hinge assembly 131 and the energy storage assembly 132 are connected by a transmission assembly 133. The transmission assembly 133 includes a first gear 1331 and a second gear 1332. The first gear 1331 is coaxially arranged with the hinge shaft 1311 and can rotate with the hinge shaft 1311. The second gear 1332 is coaxially arranged with the energy storage shaft 1323 and meshes with the first gear 1331.

[0081] It should be noted that the first gear 1331 can be detachably or non-detachably connected to the hinge shaft 1311. In the non-detachable connection, the end of the hinge shaft 1311 that mates with the first gear 1331 has a square structure, and the hole of the first gear 1331 that mates with the hinge shaft 1311 is a square hole. A retaining ring 1337 is provided on the hinge shaft 1311 to restrict the axial movement of the first gear 1331. Similarly, the second gear 1332 can be detachably or non-detachably connected to the energy storage shaft 1323. In the non-detachable connection, the end of the energy storage shaft 1323 that mates with the second gear 1332 has a square structure, and the hole of the second gear 1332 that mates with the energy storage shaft 1323 is a square hole. A retaining ring 1337 is provided on the energy storage shaft 1323 to restrict the axial movement of the second gear 1332.

[0082] The transmission assembly 133 may also include a partition 1333 and a sealing cover 1334, wherein the partition 1333 is located between the support member 1321 and the first gear 1331, and the sealing cover 1334 is sleeved on the outer periphery of the first gear 1331 and the second gear 1332.

[0083] During assembly, partition 1333 is fitted onto hinge shaft 1311 and energy storage shaft 1323, first gear 1331 is installed on hinge shaft 1311 and snapped with snap ring 1337, second gear 1332 is installed on energy storage shaft 1323 and snapped with snap ring 1337; sealing cover 1334 is fitted onto the outer periphery of first gear 1331 and second gear 1332.

[0084] It should be noted that the connection between the sealing cover 1334 and the partition 1333 is a detachable connection, such as by using a snap-fit ​​connection or a fastener connection.

[0085] The partition 1333 is provided with a sixth hole 1333a, the sealing cover 1334 is provided with a seventh hole 1334a, and the third fastener 1336 is connected to the sixth hole 1333a and the seventh hole 1334a in sequence to achieve a fixed connection between the sealing cover 1334 and the partition 1333.

[0086] The aforementioned sealing cover 1334 can be a rubber structure. Using a rubber structure can reduce the noise generated during the engagement of the first gear 1331 and the second gear 1332.

[0087] Furthermore, in order to optimize the above solution, the transmission assembly 133 may also include a protective cover 1335, wherein the protective cover 1335 is fitted around the outer periphery of the sealing cover 1334. By providing the protective cover 1335, the sealing cover 1334 can be protected, and the service life of this area can be extended.

[0088] like Figure 13As shown, this application discloses a charging pile, including a main unit 20, a charging gun cable 30, and an assist device 10 as described above, wherein the swing arm mechanism 12 of the assist device 10 is connected to the charging gun cable 30. Since the assist device 10 has the aforementioned beneficial effects, the charging pile including the assist device 10 has corresponding effects.

[0089] See Figure 14 and Figure 15 , Figure 14 A perspective view of a charging pile in a first state provided in an embodiment of this application; Figure 15 This is a perspective view of a charging pile in a second state, provided as an embodiment of this application.

[0090] In the first state described above, the charging station is not charging the vehicle; in the second state described above, the charging station is charging the vehicle.

[0091] When the charging pile is in the first state, the reset hinge 13 is in the closed state and the swing arm mechanism 12 is in the folded state; when the charging pile is in the second state, the reset hinge 13 is in the open state and the swing arm mechanism 12 is in the unfolded state.

[0092] During the process of a user pulling the charging gun cable 30 to the car's charging port, the reset hinge 13 switches from the closed state to the open state, and the swing arm mechanism 12 switches from the folded state to the unfolded state. When the user pulls the charging gun cable 30 to hang it on the main unit 20, the reset hinge 13 switches from the open state to the closed state, and the swing arm mechanism 12 switches from the unfolded state to the folded state. The swing arm mechanism 12 can support a portion of the weight of the charging gun cable 30, effectively reducing the weight of the cable itself and improving the user experience.

[0093] The aforementioned assist device 10 adopts a modular design, which can be designed into different sizes of top mounting structures according to the appearance and structural dimensions of the charging pile's main unit 20. This results in stronger compatibility, higher assembly and maintenance efficiency, and effectively reduces the secondary development and installation costs of the product.

[0094] In addition, the aforementioned assistive device 10 can prevent the charging gun cable 30 from dragging on the ground and occupying the charging parking space, making it easier for the charging vehicle owner to park, preventing the charging gun cable 30 and the gun head from being crushed, improving the service life of the charging gun cable 30, and at the same time avoiding electrical safety hazards caused by the wear and tear of the charging gun cable 30 dragging on the ground, thus improving charging safety.

[0095] The assist device 10 is fixedly connected to the top of the main unit 20. The area of ​​the top device is larger than that of the charging pile, which can prevent other objects from falling from the top and causing accidental damage to the charging pile, such as rain, snow, hail, or foreign objects.
