Description

Technical Field

[0001] This application belongs to the technical field of AC charging pile equipment, and more specifically, it relates to the shell structure of an AC charging pile and an AC charging pile. Background Technology

[0002] Existing electrical equipment, especially AC charging equipment, mostly integrates and seals the various electrical components through a casing. The casing mainly consists of a bottom shell and a top cover. For ease of maintenance, the bottom shell and top cover are hinged together using metal hinges. These metal hinges need to be connected to the bottom shell and top cover respectively with screws, resulting in low assembly efficiency for the bottom shell and top cover. Moreover, the use of metal hinges is costly, which is not conducive to further optimization of the overall cost of electrical equipment. Utility Model Content

[0003] The purpose of this application is to provide an outer shell structure and an AC charging pile, which aims to solve the problems of cumbersome assembly steps and high cost of hinge components in the existing AC charging pile outer shell.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide an outer casing structure for an AC charging pile, comprising: Bottom shell, top cover, first hinge seat, second hinge seat, hinge pin and snap fastener; The first hinge seat is integrally connected to the upper cover, and the second hinge seat is integrally connected to the bottom shell; the first hinge seat and the second hinge seat are alternately arranged along a first direction; The hinge pin passes through the first hinge seat and the second hinge seat in the first direction to realize the hinge connection between the first hinge seat and the second hinge seat, and a snap-fit ​​groove is provided on the outer peripheral surface of the protruding end of the hinge pin. The snap-fit ​​element is disposed on the first hinge seat or the second hinge seat and can be snapped into the snap-fit ​​groove to limit the displacement of the hinge pin in the first direction.

[0005] Existing hardware hinge components mainly consist of a movable hinge plate, a stationary hinge plate, and a hinge shaft. Hinge holes are provided on both the movable and stationary hinge plates, and the hinge shaft passes through these holes to achieve hinge connection between the movable and stationary hinge plates. Subsequently, the stationary hinge plate is fixed to the bottom shell with screws, and the movable hinge plate is fixed to the top cover with screws, ultimately achieving hinge connection between the top cover and the bottom shell. It is evident that the assembly process of the hardware hinge components is cumbersome, requiring the tightening of multiple screws. Furthermore, considering manufacturing and assembly errors, the positions of the movable hinge plate and the top cover, as well as the positions of the stationary hinge plate and the bottom shell, need to be adjusted during assembly, further extending the assembly time. In addition, the hardware hinge components are entirely independent of the top cover and bottom shell. Besides the aforementioned core components, positioning components are also required between the hinge shaft and the movable and stationary hinge plates to prevent the hinge shaft from detaching. Therefore, the hardware hinge components have a large number of parts, resulting in high manufacturing and usage costs.

[0006] Compared with the prior art, the solution shown in this application embodiment has a first hinge seat integrally connected to the upper cover and a second hinge seat integrally connected to the bottom shell. During assembly of the bottom shell and upper cover, the first hinge seat is directly aligned with the second hinge seat. Then, a hinge pin is inserted into the first and second hinge seats, and a snap-fit ​​component is connected to the protruding end of the hinge pin. The axial position of the hinge pin is locked by the snap-fit ​​component engaging with the snap-fit ​​groove, ensuring the reliability of the connection between the first and second hinge seats. The outer shell structure of the AC charging pile of this application eliminates the need for a separate static hinge plate on the bottom shell and a separate movable hinge plate on the upper cover; only the hinge pin needs to be inserted and fixed. This eliminates the need for assembly with screws, simplifies the hinge installation process between the upper cover and the bottom shell, and saves assembly time. In addition, the first hinge seat, the second hinge seat, the hinge pin, and the snap fastener constitute the hinged mounting structure. The first hinge seat and the second hinge seat are integrally connected to the top cover and the bottom shell, respectively. The only components that can be disassembled and installed independently are the hinge pin and the snap fastener. The overall number of components in the hinged mounting structure is small, which can effectively reduce the manufacturing and use costs of the hinged mounting structure, and thus help reduce the overall assembly and manufacturing costs of the AC charging pile's outer shell structure.

[0007] In conjunction with the first aspect, in one possible implementation, the snap-fit ​​groove is an annular groove continuously distributed circumferentially along the hinge pin.

[0008] In conjunction with the first aspect, in one possible implementation, the snap-fit ​​component includes a resilient snap-fit ​​ring, the circumferential sidewall of which has an assembly notch for the hinge pin to enter and exit, and when the hinge pin is located in the internal space of the resilient snap-fit ​​ring, the inner ring of the resilient snap-fit ​​ring can engage with the snap-fit ​​groove.

[0009] In some embodiments, the inner ring of the elastic snap ring is provided with a plurality of snap protrusions spaced apart along the circumference of the elastic snap ring, and when the hinge pin is located in the internal space of the elastic snap ring, the snap protrusions are engaged in the snap groove.

[0010] In conjunction with the first aspect, in one possible implementation, the snap-fit ​​element includes an elastic snap connected to the first hinge seat, the elastic snap being capable of engaging with the snap-fit ​​groove.

[0011] In some embodiments, a first hinge mounting hole is provided through the first hinge seat along a first direction, and a second hinge mounting hole is provided through the second hinge seat along the first direction. The hinge pin passes through the first hinge mounting hole and the second hinge mounting hole along the first direction. The elastic buckle is disposed in the first hinge mounting hole or the second hinge mounting hole.

[0012] In some embodiments, multiple elastic buckles are provided, and the multiple elastic buckles are evenly distributed in the circumferential direction of the first hinge mounting hole or the second hinge mounting hole.

[0013] In conjunction with the first aspect, in one possible implementation, a first hinge mounting hole is provided through the first hinge seat along a first direction, and a second hinge mounting hole is provided through the second hinge seat along the first direction, wherein the hinge pin passes through the first hinge mounting hole and the second hinge mounting hole along the first direction. The end face of the first hinge seat opposite to the upper cover is an arc-shaped surface coaxially arranged with the first hinge mounting hole, and the end face of the second hinge seat opposite to the bottom shell is an arc-shaped surface coaxially arranged with the second hinge mounting hole.

[0014] In conjunction with the first aspect, in one possible implementation, a plurality of hinged connection units distributed along a first direction are provided between the upper cover and the bottom shell. In each hinged connection unit, two sets of first hinge seats are provided, the two sets of first hinge seats are spaced apart along the first direction, and an accommodating space is formed between them, and the second hinge seat is inserted into the accommodating space.

[0015] Secondly, this application also provides an AC charging pile, including electrical components and the aforementioned AC charging pile housing structure, wherein the electrical components are housed within the bottom shell of the AC charging pile housing structure and are sealed by the top cover of the AC charging pile housing structure.

[0016] Compared with the prior art, the solution shown in this application, by adopting the above-mentioned shell structure of the AC charging pile with lower assembly and manufacturing costs, helps to reduce the overall assembly and manufacturing costs of the AC charging pile, thereby enhancing product competitiveness.

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0021] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] Existing hardware hinge components mainly consist of a movable hinge plate, a stationary hinge plate, and a hinge shaft. Hinge holes are provided on both the movable and stationary hinge plates, and the hinge shaft passes through these holes to achieve hinge connection between the movable and stationary hinge plates. Subsequently, the stationary hinge plate is fixed to the bottom shell with screws, and the movable hinge plate is fixed to the top cover with screws, ultimately achieving hinge connection between the top cover and the bottom shell. It is evident that the assembly process of the hardware hinge components is cumbersome, requiring the tightening of multiple screws. Furthermore, considering manufacturing and assembly errors, the positions of the movable hinge plate and the top cover, as well as the positions of the stationary hinge plate and the bottom shell, need to be adjusted during assembly, further extending the assembly time. In addition, the hardware hinge components are entirely independent of the top cover and bottom shell. Besides the aforementioned core components, positioning components are also required between the hinge shaft and the movable and stationary hinge plates to prevent the hinge shaft from detaching. Therefore, the hardware hinge components have a large number of parts, resulting in high manufacturing and usage costs.

[0024] To resolve the above issues, please refer to the following: Figures 1 to 11 The outer shell structure of the AC charging pile provided in this application is now described. The outer shell structure of the AC charging pile includes a bottom shell 100, a top cover 200, a first hinge seat 300, a second hinge seat 400, a hinge pin 500, and a snap-fit ​​component 600. The first hinge seat 300 is integrally connected to the top cover 200, and the second hinge seat 400 is integrally connected to the bottom shell 100. The first hinge seat 300 and the second hinge seat 400 are alternately arranged along a first direction. The hinge pin 500 passes through the first hinge seat 300 and the second hinge seat 400 along the first direction to achieve hinge between the first hinge seat 300 and the second hinge seat 400. A snap-fit ​​groove 501 is formed on the outer peripheral surface of the protruding end of the hinge pin 500. The snap-fit ​​component 600 is disposed on the first hinge seat 300 or the second hinge seat 400 and can be snapped into the snap-fit ​​groove 501 to limit the displacement of the hinge pin 500 in the first direction. Figure 1 The solid arrow in the straight line indicates the first direction.

[0025] In this embodiment, the integral connection between the first hinge seat 300 and the upper cover 200, and the integral connection between the second hinge seat 400 and the bottom shell 100, are implemented in ways including but not limited to integral injection molding and casting. The specific connection method depends on the material of the upper cover 200 and the bottom shell 100. For example, if the first hinge seat 300, the upper cover 200, the second hinge seat 400, and the bottom shell 100 are all made of plastic (e.g., polycarbonate), integral injection molding is used; if the first hinge seat 300, the upper cover 200, the second hinge seat 400, and the bottom shell 100 are all made of metal (e.g., galvanized steel sheet), integral casting is used.

[0026] In this embodiment, if the hinge pin 500 eventually protrudes from the first hinge seat 300, the protruding end is positioned near the first hinge seat 300, and the snap-fit ​​member 600 is directly connected to the first hinge seat 300, or the snap-fit ​​member 600 is positioned near the first hinge seat 300; if the hinge pin 500 eventually protrudes from the second hinge seat 400, the protruding end is positioned near the second hinge seat 400, and the snap-fit ​​member 600 is directly connected to the second hinge seat 400, or the snap-fit ​​member 600 is positioned near the second hinge seat 400. The hinge pin 500 has a head 510, and the snap-fit ​​member 600 cooperates with the head 510 to simultaneously clamp the first junction seat and the second hinge seat 400 from both ends, thereby achieving axial positioning of the hinge pin 500.

[0027] Compared with the prior art, the outer shell structure of the AC charging pile provided in this application has the following advantages: the first hinge seat 300 is integrally connected to the upper cover 200, and the second hinge seat 400 is integrally connected to the bottom shell 100. When assembling the bottom shell 100 and the upper cover 200, the first hinge seat 300 is directly aligned with the second hinge seat 400. Then, the hinge pin 500 is inserted into the first hinge seat 300 and the second hinge seat 400, and a snap-fit ​​member 600 is connected to the protruding end of the hinge pin 500. The axial position of the hinge pin 500 is locked by the snap-fit ​​member 600 and the snap-fit ​​groove 501, ensuring the reliability of the connection between the first hinge seat 300 and the second hinge seat 400. The outer shell structure of the AC charging pile of this application eliminates the need for a separate static hinge plate on the bottom shell 100 and a separate movable hinge plate on the top cover 200. Only the hinge pin 500 needs to be inserted and fixed, eliminating the need for screw assembly and simplifying the hinge installation process between the top cover 200 and the bottom shell 100, thus saving assembly time. Furthermore, the first hinge seat 300, the second hinge seat 400, the hinge pin 500, and the snap-fit ​​component 600 constitute the hinge installation structure. The first hinge seat 300 and the second hinge seat 400 are integrally connected to the top cover 200 and the bottom shell 100, respectively. Only the hinge pin 500 and the snap-fit ​​component 600 are independently detachable. The overall hinge installation structure has fewer components, effectively reducing the manufacturing and usage costs of the hinge installation structure, thereby helping to reduce the overall assembly and manufacturing costs of the AC charging pile's outer shell structure.

[0028] In some embodiments, see Figure 3 The end face of the hinge pin 500 away from its head 510 is flat, and this end face and the outer peripheral surface of the hinge pin 500 are chamfered to facilitate the insertion of this end into the first hinge seat 300 or the second hinge seat 400.

[0029] In some embodiments, see Figure 3The snap-fit ​​groove 501 is an annular groove continuously distributed along the circumference of the hinge pin 500. This design allows for more flexible snap-fit ​​adaptation between the hinge pin 500 and the snap-fit ​​part 600. In the circumferential direction of the hinge pin 500, there is no need for precise alignment between the hinge pin 500 and the snap-fit ​​part 600, which reduces assembly difficulty and improves assembly efficiency.

[0030] In some embodiments, see Figure 4 The snap-fit ​​component 600 includes an elastic snap-fit ​​ring 610. The circumferential sidewall of the elastic snap-fit ​​ring 610 has an assembly notch 611 for the hinge pin 500 to enter and exit. The width of the assembly notch 611 is smaller than the diameter of the snap-fit ​​groove 501 on the hinge pin 500. During assembly, the hinge pin 500 is inserted into the assembly notch 611, and the elastic snap-fit ​​ring 610 undergoes a certain degree of elastic deformation. When the hinge pin 500 is fully inserted into the internal space of the elastic snap-fit ​​ring 610, the elastic snap-fit ​​ring 610 returns to its original position, and its inner ring engages with the snap-fit ​​groove 501. Disassembly can be achieved by reversing the operation. In this embodiment, the elastic snap-fit ​​ring 610 is independently provided from the first hinge seat 300 and the second hinge seat 400. It has a simple structure and is easy to assemble, and it does not affect the structure of the first hinge seat 300 and the second hinge seat 400, thus simplifying the structure of the first hinge seat 300 and the second hinge seat 400 and making manufacturing easier.

[0031] In some specific embodiments of the resilient snap ring 610, see [reference] Figure 4 The inner ring of the elastic snap-fit ​​ring 610 is provided with a plurality of snap-fit ​​protrusions 612 distributed circumferentially along the elastic snap-fit ​​ring 610. When the hinge pin 500 is located in the internal space of the elastic snap-fit ​​ring 610, the snap-fit ​​protrusions 612 are engaged in the snap-fit ​​groove 501. In this embodiment, by setting the snap-fit ​​protrusions 612, a notch is formed between two adjacent snap-fit ​​protrusions 612. This notch can enhance the deformation capability of the elastic snap-fit ​​ring 610, so that the hinge pin 500 can enter and exit the assembly notch 611 more smoothly. At the same time, by engaging the snap-fit ​​protrusions 612 with the snap-fit ​​groove 501, the snap-fit ​​contact area is reduced and the snap-fit ​​contact points are increased, which is beneficial to improving the reliability of the snap-fit ​​contact and reducing the problem of poor snap-fit ​​contact caused by manufacturing and assembly errors.

[0032] In this embodiment, the elastic snap ring 610 is made of spring carbon steel or stainless steel.

[0033] More specifically, in the direction toward the axis of the elastic snap ring 610, the width of the snap protrusion 612 gradually decreases, forming a trapezoidal protrusion that is wider on the outside and narrower on the inside. By utilizing the high structural stability of the trapezoid, the problem of deformation of the snap protrusion 612 is avoided during loading, unloading and snapping.

[0034] In other embodiments, see Figure 11The snap-fit ​​component 600 includes an elastic snap 620 connected to the first hinge base 300, which can snap into the snap-fit ​​groove 501. During assembly, the hinge pin 500 pushes the elastic snap 620 away from the axis of the first hinge base 300 or the second hinge base 400. After being inserted into place, the elastic snap 620 aligns with the snap-fit ​​groove 501 and moves back to its original position towards the axis of the first hinge base 300 or the second hinge base 400, thus achieving snap-fit ​​with the snap-fit ​​groove 501. In this embodiment, the elastic snap 620 is integrated into the first hinge base 300 or the second hinge base 400, reducing the number of independent parts and effectively avoiding the problem of losing small parts.

[0035] In this embodiment, the elastic buckle 620 is disposed on the hinge seat adjacent to the protruding end of the hinge pin 500. For example, if the hinge pin 500 protrudes from the first hinge seat 300, the elastic buckle 620 is disposed on the first hinge seat 300. In this way, the sliding distance of the elastic buckle 620 on the hinge pin 500 during assembly can be shortened, achieving quick engagement. In addition, the position of the elastic buckle 620 on the first hinge seat 300 or the second hinge seat 400 can be on the shaft end face of the corresponding hinge seat, or on the outer peripheral surface of the corresponding hinge seat, or inside the corresponding hinge seat; no single limitation is made here.

[0036] In some specific embodiments of the elastic snap 620, see [reference needed]. Figure 11 A first hinge mounting hole 301 is formed through the first hinge seat 300 along a first direction, and a second hinge mounting hole 401 is formed through the second hinge seat 400 along the first direction. A hinge pin 500 passes through the first hinge mounting hole 301 and the second hinge mounting hole 401 along the first direction to achieve hinged assembly of the first hinge seat 300 and the second hinge seat 400. Based on this, the elastic buckle 620 is provided in the first hinge mounting hole 301 or the second hinge mounting hole 401 to avoid the problem of the elastic buckle 620 being exposed and easily damaged by bumps. There is no need to specially set a clearance structure for the elastic buckle 620 on the top cover 200 or the base. At the same time, it can also improve the integration of the first hinge seat 300 and the snap fastener 600 or the second hinge seat 400 and the snap fastener 600, and improve the aesthetics after assembly.

[0037] Assuming the elastic buckle 620 is positioned within the first hinge mounting hole 301, the implementation method of the elastic buckle 620 in this embodiment is illustrated as follows: 1) Refer to Figure 111) A stepped relief groove is provided in the first hinge mounting hole 301. The elastic buckle 620 extends axially along the first hinge mounting hole 301. One end of the buckle is set on the stepped surface of the stepped relief groove, and the other end protrudes towards the axial direction of the first hinge mounting hole 301 to form a snap-fit ​​end. The snap-fit ​​end can snap with the snap-fit ​​groove 501. 2) Not shown in the figure, the inner wall of the first hinge mounting hole 301 is provided with a receiving groove that extends radially along the first hinge mounting hole 301. The bottom of the receiving groove is provided with an elastic pusher. The other end of the elastic pusher is connected to a snap-fit ​​slider. The snap-fit ​​slider is slidably connected to the receiving groove. The elastic pusher is configured with a preload force to make the snap-fit ​​slider extend out of the receiving groove. The snap-fit ​​slider can snap with the snap-fit ​​groove 501.

[0038] In some embodiments, see Figure 11 Multiple elastic buckles 620 are provided, and the multiple elastic buckles 620 are evenly distributed in the circumferential direction of the first hinge mounting hole 301 or the second hinge mounting hole 401. This can reduce the contact area between a single elastic buckle 620 and the snap-fit ​​groove 501, improve the reliability of the snap-fit ​​contact, and at the same time, improve the uniformity of the snap-fit ​​force by increasing the number of snap-fit ​​positions.

[0039] In some embodiments, see Figure 2 , Figures 5 to 11 The first hinge seat 300 has a first hinge mounting hole 301 extending through it along the first direction, and the second hinge seat 400 has a second hinge mounting hole 401 extending through it along the first direction. The hinge pin 500 passes through the first hinge mounting hole 301 and the second hinge mounting hole 401 along the first direction. The end face of the first hinge seat 300 facing away from the upper cover 200 is an arc-shaped surface coaxial with the first hinge mounting hole 301, and the end face of the second hinge seat 400 facing away from the bottom shell 100 is an arc-shaped surface coaxial with the second hinge mounting hole 401. By setting an arc-shaped surface, during the rotation and opening of the upper cover 200, the distance between the end face of the first hinge seat 300 and the bottom shell 100 remains unchanged, and the distance between the end face of the second hinge seat 400 and the upper cover 200 remains unchanged. This can make the first hinge seat 300 closer to the bottom shell 100 and the second hinge seat 400 closer to the upper cover 200, thereby making the assembly distance between the upper cover 200 and the bottom shell 100 smaller and the structure more compact.

[0040] In some embodiments, see Figure 1 and Figure 2 To ensure uniform force distribution during the hinge assembly, multiple hinge connection units distributed along the first direction are provided between the upper cover 200 and the bottom shell 100. Each hinge connection unit forms a hinge connection point. Figure 1An embodiment with two hinged connection units is shown. In each hinged connection unit, two sets of first hinge seats 300 are provided, the two sets of first hinge seats 300 are spaced apart along a first direction, and a receiving space 700 is formed between them, and a second hinge seat 400 is inserted into the receiving space 700. In a single hinged connection unit, a hinge pin 500 is inserted from one side of the first hinge seat 300 and protrudes from the other side of the first hinge seat 300, at which time a snap-fit ​​member 600 is provided at the other side of the first hinge seat 300. This embodiment further improves the reliability of assembly by forming the receiving space 700 and using the first hinge seat 300 to axially limit the second hinge seat 400.

[0041] Examples of other spatial distributions of the first hinge seat 300 and the second hinge seat 400 are as follows: 1) In a single hinged connection unit, a first hinge seat 300 and a second hinge seat 400 are each provided in a set. The end face of the first hinge seat 300 is in contact with the end face of the second hinge seat 400. At least two hinged connection structures are provided between the upper cover 200 and the bottom shell 100 along a first direction. In a single hinged connection unit, the hinge pin 500 can be inserted from the first hinge seat 300 and protrude from the second hinge seat 400. In this case, the snap-fit ​​member 600 is provided on the side of the second hinge seat 400 away from the first hinge seat 300; or, the hinge pin 500 can be inserted from the second hinge seat 400 and protrude from the first hinge seat 300. In this case, the snap-fit ​​member 600 is provided on the side of the first hinge seat 300 away from the second hinge seat 400.

[0042] 2) In a single hinged connection unit, one set of first hinge seats 300 and two sets of second hinge seats 400 are provided, with the first hinge seat 300 located between the two sets of second hinge seats 400. In a single hinged connection unit, the hinge pin 500 is inserted from one side of the second hinge seat 400 and protrudes from the other side of the second hinge seat 400, at which time the snap-fit ​​member 600 is provided at the other side of the second hinge seat 400.

[0043] In some embodiments, see Figures 7 to 10 Because the second hinge seat 400 is subjected to greater force, a seat support rib 110 is provided between the bottom shell 100 and the second hinge seat 400 to strengthen the support of the second hinge seat 400 and prevent deformation or breakage of the second hinge seat 400. In specific implementation, multiple sets of seat support ribs 110 are arranged on the side of the second hinge seat 400 along the first direction to improve the support strength.

[0044] In some embodiments, see Figure 1 , Figure 2 , Figure 5 and Figure 11The upper cover 200 has an outer perimeter plate 210 at its edge, and an inner perimeter plate 220 on the inner side of the outer perimeter plate 210. A hinged mounting space 201 is formed between the outer perimeter plate 210 and the inner perimeter plate 220, and a first hinge seat 300 is disposed within the hinged mounting space 201. After the upper cover 200 is fastened, the outer perimeter plate 210 surrounds the outer periphery of the opening end of the base, and the inner perimeter plate 220 abuts against the opening end face of the base. The outer perimeter plate 210 and the inner perimeter plate 220 cooperate to form a structure similar to a reinforcing flange at the edge of the upper cover 200, preventing the edge of the upper cover 200 from bending and deforming, thereby improving the overall torsional strength of the upper cover 200.

[0045] In some embodiments, the top cover 200 is further provided with a grid-like distribution of reinforcing ribs 230 on the side facing the bottom shell 100. The reinforcing ribs 230 are located inside the inner enclosure 220 and are integrally connected with the inner enclosure 220 to form a grid-like reinforcing structure.
