Description

Technical Field

[0001] This application belongs to the field of vehicle electrical system technology, and more specifically, relates to a charging socket installation structure and a vehicle. Background Technology

[0002] Charging sockets are an indispensable electrical component for new energy electric vehicles. As the market for new energy electric vehicles continues to expand, the installation layout of charging sockets on the vehicle body is becoming more and more user-friendly. However, regardless of how the installation location of the charging socket changes, its installation and fixing method is still mainly based on direct connection with fasteners.

[0003] The charging sockets of new energy electric vehicles are usually integrated into a modular structure with high-voltage wiring harnesses. During assembly, due to the constraints of the high-voltage wiring harness and the limitation of installation space, it is very difficult to align the charging socket with the connection holes on the body sheet metal used for fasteners. Misalignment of the connection holes often affects the accuracy of the assembly position, which in turn affects the sealing reliability between the charging socket and the body sheet metal. In addition, the installation space of the charging socket is cramped, and it is difficult to obtain a clear operating view from the inside of the body sheet metal. This further increases the assembly difficulty of the charging socket and seriously affects the work efficiency. Utility Model Content

[0004] The purpose of this application is to provide a charging socket installation structure that aims to reduce the assembly difficulty of the charging socket and improve the assembly position accuracy and efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, the embodiments of this application provide a charging socket installation structure, including a vehicle body sheet metal and a socket body; the vehicle body sheet metal is provided with mounting holes, the socket body passes through the mounting holes, and the plug-in end of the socket body faces the outside of the vehicle body sheet metal, and the wire harness end faces the inside of the vehicle body sheet metal. The outer periphery of the socket body has a mounting plate, which is sealed and attached to the body sheet metal and can be detachably fixed to the body sheet metal; one of the mounting plate and the body sheet metal is provided with a first snap-fit ​​part, and the other of the two is provided with a second snap-fit ​​part. The first snap-fit ​​part and the second snap-fit ​​part are snapped together to form a pre-installed connection point, which is used to pre-install and position the socket body.

[0006] The beneficial effect of the charging socket installation structure provided in this application embodiment is that, compared with the prior art, the mounting plate on the outer periphery of the socket body can be stably attached to the surface of the vehicle body sheet metal, and the contact surface between the mounting plate and the vehicle body sheet metal can serve as a sealing surface to ensure the connection sealing between the socket body and the vehicle body sheet metal, preventing water droplets splashed on the inner side of the vehicle body sheet metal from penetrating to the plug-in terminal of the socket body when the vehicle is wading through water.

[0007] The mounting plate and the body sheet metal are respectively provided with a first snap-fit ​​part and a second snap-fit ​​part as pre-installation connection points. During the assembly operation, the first snap-fit ​​part and the second snap-fit ​​part can be used to snap together, so that the socket body is pre-installed and positioned on the body sheet metal. Since the snap-fit ​​method is conducive to blind installation operation, it is less dependent on the operation field of vision. It can not only reduce the difficulty of assembling the socket body on the body sheet metal and help improve the assembly efficiency, but also improve the assembly position accuracy of the socket body through the snap-fit ​​positioning of the first snap-fit ​​part and the second snap-fit ​​part. This can avoid the sealing problem caused by the assembly position error of the socket body and reduce the difficulty of subsequent fastening connection operation, which can further improve the assembly efficiency.

[0008] In conjunction with the first aspect, in one possible implementation, a limiting hole is provided on one side of the mounting hole to form a first snap-fit ​​portion, and the second snap-fit ​​portion includes a first buckle and a second buckle provided on the mounting plate; wherein, the first buckle is inserted through the limiting hole and snaps with the edge of the limiting hole facing the mounting hole to form a pre-installed connection point; the second buckle passes through the mounting hole and snaps with the edge of the mounting hole away from the limiting hole to form another pre-installed connection point.

[0009] In the above technical solution, considering that it is more convenient to make holes in the body sheet metal than to set buckles, and that the buckle structure can be directly integrally formed on the mounting plate, a limiting hole is set on the body sheet metal as the first snap-fit ​​part, and a first buckle and a second buckle are set on the mounting plate as the second snap-fit ​​part. During assembly, the first buckle is passed through the limiting hole and snapped with the edge of the limiting hole. This not only allows the limiting hole to position the first buckle, but also uses the snap-fit ​​between the first buckle and the limiting hole, and the snap-fit ​​between the second buckle and the edge of the mounting hole to form pre-installed connection points on both sides of the mounting hole. This allows the mounting plate to be stably snapped onto the body sheet metal, which facilitates the subsequent fastening operation of the mounting plate.

[0010] In some embodiments, the first snap fastener includes a first limiting rib and a first snap connector; wherein the first limiting rib is inserted through a limiting hole and has a range of motion within the limiting hole to approach or move away from the mounting hole; the first snap connector is connected to the end of the first limiting rib away from the mounting plate and bent toward the mounting hole, and the first snap connector is adapted to pass through the limiting hole and snap onto the edge of the limiting hole.

[0011] In the above technical solution, the first buckle is L-shaped based on the first limiting rib and the bent first snap connector. When the socket body is pre-installed, the first snap connector passes through the limiting hole and moves the socket body along the surface of the body sheet metal based on the amount of movement between the first limiting rib and the limiting hole, so that the first snap connector is locked at the edge of the limiting hole. This can lock and position the socket body in all directions except the reverse direction of movement. It is not only convenient to operate and suitable for blind installation, but also improves the installation position accuracy of the socket body. Based on the above pre-installation positioning, the assembly stability of the socket body is achieved by fastening the mounting plate to the body sheet metal. When it is necessary to disassemble the socket body, it is only necessary to remove the fastening connection between the mounting plate and the body sheet metal, and then move the socket body in the reverse direction to make the first snap connector come out of the limiting hole. The operation is simple and convenient.

[0012] For example, a limiting groove is provided on the edge of the mounting hole away from the limiting hole, and the second buckle is at least partially embedded in the limiting groove.

[0013] In the above technical solution, setting a limiting groove at the edge of the mounting hole can, on the one hand, allow the second buckle to be partially or entirely embedded in the limiting groove, thereby preventing the first buckle from occupying the internal space of the mounting hole after assembly. On the other hand, the second buckle can achieve a limiting effect by engaging with the limiting groove, thereby improving the pre-installation position accuracy of the socket body in the mounting hole, which facilitates subsequent fastening operations and prevents the socket body from being misaligned during the fastening process, thus affecting the final connection stability and sealing and waterproof performance.

[0014] For example, the second buckle includes a second limiting rib and a second locking connector; wherein, the second limiting rib is embedded in the limiting groove in the direction away from the mounting hole; the second locking connector is connected to the end of the second limiting rib away from the mounting plate and bent away from the mounting hole, and the second locking connector is engaged with the edge of the limiting groove.

[0015] In the above technical solution, the first limiting rib and the bent second snap connector form an L-shaped second snap fastener. During pre-installation, the socket body moves as a whole based on the movement of the first snap fastener within the limiting hole, thereby embedding the second limiting rib into the limiting groove and snapping the second snap connector onto the edge of the limiting groove. Based on this, the cooperation between the first snap fastener and the limiting hole ensures that both sides of the socket body obtain stable pre-installation connection points, thus enabling the socket body to achieve reliable pre-installation positioning before final tightening. This not only helps reduce the difficulty of subsequent tightening operations and improves work efficiency, but also improves the installation position accuracy of the socket body, preventing the mounting plate from misaligning on the vehicle body sheet metal, which could affect the tightness of the fit and lead to poor sealing.

[0016] In one possible implementation, the mounting plate is sealed and fitted to the inner side of the body sheet metal, and the body sheet metal is provided with several connectors from the outside to the inside, each connector being securely connected to the mounting plate.

[0017] In the above technical solution, the mounting plate is sealed and attached to the inner side of the body sheet metal, which eliminates the step of passing the wiring harness from the outside of the body sheet metal through the mounting hole to the inside during assembly, thereby improving production cycle and assembly efficiency. With the mounting plate attached to the inner side of the body sheet metal, the connector can pass through from the outside of the body sheet metal and be fixed to the mounting plate. This allows the operating end of the connector to be exposed, providing a clear operating view and facilitating the tightening of the connector, further improving assembly efficiency. Furthermore, the mounting plate's attachment to the inner side of the body sheet metal ensures that there is only one mating seam between the edge of the mounting plate and the body sheet metal. Reliably sealing this seam prevents water from the inside of the body sheet metal from leaking to the plug-in end of the connector, thus improving the vehicle's wading performance.

[0018] In some embodiments, a sealing gasket is sandwiched between the mounting plate and the inner side of the vehicle body sheet metal.

[0019] In the above technical solution, a sealing gasket is sandwiched between the mounting plate and the body sheet metal to seal the joint between the two, thereby improving the connection sealing between the mounting plate and the body sheet metal, and thus improving the waterproof performance of the socket body.

[0020] For example, a reinforcing sheet metal is attached to the outer side of the body sheet metal. The reinforcing sheet metal has clearance holes that match the contour of the mounting holes and through holes suitable for correspondingly passing through each connector. The reinforcing sheet metal and the body sheet metal together form a pre-installed connection point with the mounting plate.

[0021] In the above technical solution, the structural strength of the mounting hole area can be improved by attaching additional reinforcing sheet metal. At the same time, matching features that are exactly the same as those on the body sheet metal used to connect the socket body are set on the reinforcing sheet metal. This is equivalent to forming a double-layer sheet metal structure in the mounting area of ​​the socket body, thereby improving the connection stability of the socket body and avoiding deformation of the body sheet metal due to stress during the plugging and unplugging of the charging head.

[0022] For example, the edges of the reinforced sheet metal have reinforced folds that are away from the body sheet metal.

[0023] In the above technical solution, by setting a reinforced folded edge, the structural rigidity of the reinforced sheet metal itself can be improved, thereby improving the rigidity of the connection area between the body sheet metal and the plug-in body, avoiding problems such as poor sealing and damage to the appearance caused by the deformation of the plug-in body during the plugging and unplugging of the charging head.

[0024] Secondly, embodiments of this application also provide a vehicle including the aforementioned charging socket mounting structure.

[0025] The beneficial effects of the vehicle provided in this application embodiment are that, compared with the prior art, it adopts the above-mentioned charging socket installation structure. The mounting plate and the body sheet metal are respectively provided with a first snap-fit ​​part and a second snap-fit ​​part as pre-installation connection points. During the assembly operation, the first snap-fit ​​part and the second snap-fit ​​part can be snapped together first, so that the socket body can be pre-installed and positioned on the body sheet metal. Since the snap-fit ​​method is conducive to blind installation operation, it has less dependence on the operation field of vision. It can not only reduce the difficulty of assembling the socket body on the body sheet metal and help improve the assembly operation efficiency, but also improve the assembly position accuracy of the socket body through the snap-fit ​​positioning of the first snap-fit ​​part and the second snap-fit ​​part. This can avoid the sealing problem caused by the assembly position error of the socket body and reduce the difficulty of subsequent fastening connection operation, which is conducive to further improving the assembly operation efficiency.

[0029] 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.

[0030] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not 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.

[0031] 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, "a few" means two or more, unless otherwise explicitly specified.

[0032] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", the bottom of the vehicle represents "down", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the driver's cab.

[0033] In addition, the front-rear direction of the vehicle body as defined in the embodiments of this application refers to the front-rear direction of the vehicle's forward direction during driving; the left-right direction of the vehicle body as defined refers to the left-right direction of the vehicle's forward direction during driving; and the up-down direction of the vehicle body as defined refers to the up-down direction of the vehicle's forward direction during driving.

[0034] It should be noted that, as Figure 1 As shown, the end of the charging socket used to plug in the charging power plug is the plug end 201. The plug end 201 should face the outside of the vehicle body and be sealed to the charging port box 30. The charging port box 30 is structurally similar to the fuel filler box of a traditional fuel vehicle, and will not be described in detail here. The other end of the charging socket, away from the plug end 201, is connected to the wiring harness to form the wiring harness end 202. Normally, before the charging socket is installed on the vehicle body, it is already assembled into an integral module with the wiring harness. Therefore, when installing the charging socket, if an external installation is used, the wiring harness must first be passed through the mounting hole and fixed to the body sheet metal. However, the wiring harness connecting the charging socket is a high-voltage wiring harness, which is very heavy and difficult to bend. In addition, the space inside the body sheet metal is small, which makes the alignment between the charging socket and the installation position on the body sheet metal extremely difficult. Even if the charging socket and the connection hole on the body sheet metal can be aligned, the charging socket may be misaligned due to the existence of connection gaps during the tightening of the threaded connectors. It is precisely because aligning the charging socket with the connecting holes on the body sheet metal is very difficult that it is not uncommon for the connecting parts to be unable to pass through due to misalignment of the connecting holes. These situations severely restrict the assembly efficiency of the charging socket.

[0035] It should be explained that in the prior art, common installation locations for charging sockets on the vehicle body include the front and rear of the vehicle. In the embodiments of this application, the charging socket can also be installed at any location on the vehicle body based on actual needs, and no specific location limitation is made here. In the following embodiments, the charging socket is described as being installed at the rear of the vehicle body (equivalent to the location of the fuel filler cap on a fuel vehicle).

[0036] Please refer to the following: Figures 1 to 6 The charging socket installation structure provided in this application is described below. The charging socket installation structure includes a vehicle body sheet 10 and a socket body 20. The vehicle body sheet 10 has mounting holes 11, and the socket body 20 passes through the mounting holes 11. The plug-in end 201 of the socket body 20 faces the outer side of the vehicle body sheet 10, and the wiring harness end 202 faces the inner side of the vehicle body sheet 10. The outer periphery of the socket body 20 has a mounting plate 21, which is sealed and fitted to the vehicle body sheet 10 and detachably fixed to it. One of the mounting plate 21 and the vehicle body sheet 10 has a first snap-fit ​​portion, and the other has a second snap-fit ​​portion. The first snap-fit ​​portion and the second snap-fit ​​portion are correspondingly snapped together to form a pre-installation connection point 22, which is used to pre-install and position the socket body 20.

[0037] It should be noted that in this embodiment, the socket body 20 can be installed from the outside in, so that the mounting plate 21 is sealed to the outer side of the body sheet metal 10 and fixed with fasteners such as bolts; the socket body 20 can also be installed from the inside out, so that the mounting plate 21 is sealed to the inner side of the body sheet metal 10 and fixed with bolts. Regardless of whether the installation method is internal or external, pre-installation positioning is performed before fixing with fasteners. The pre-installation positioning process uses the first snap-fit ​​part and the second snap-fit ​​part to form a pre-installation connection point 22. The position of the socket body 20 is defined by the pre-installation connection point 22, thereby achieving accurate alignment between the socket body 20 and the body sheet. This not only facilitates the subsequent fastening of fasteners, but also prevents misalignment of the socket body 20 before the fasteners are tightened, thus avoiding affecting the positional accuracy of the socket body 20 after final fixing.

[0038] Compared with the prior art, the charging socket installation structure provided in this application has an installation plate 21 on the outer periphery of the socket body 20 that can stably adhere to the surface of the body sheet metal 10. Furthermore, the contact surface between the installation plate 21 and the body sheet metal 10 can serve as a sealing surface to ensure the sealing of the connection between the socket body 20 and the body sheet metal 10, thereby preventing water droplets splashed on the inner side of the body sheet metal 10 from penetrating to the plug-in terminal 201 of the socket body 20 when the vehicle is wading through water.

[0039] The mounting plate 21 and the body sheet metal 10 are respectively provided with a first snap-fit ​​part and a second snap-fit ​​part as pre-installation connection points 22. During the assembly operation, the first snap-fit ​​part and the second snap-fit ​​part can be used to snap-fit ​​together, so that the socket body 20 is pre-installed and positioned on the body sheet metal 10. Since the snap-fit ​​method is conducive to blind installation operation, it is less dependent on the operation field of vision. It can not only reduce the difficulty of assembling the socket body 20 on the body sheet metal 10 and help improve the assembly operation efficiency, but also improve the assembly position accuracy of the socket body 20 through the snap-fit ​​positioning of the first snap-fit ​​part and the second snap-fit ​​part. This can avoid the sealing problem caused by the assembly position error of the socket body 20 and reduce the difficulty of subsequent fastening connection operation, which is conducive to further improving the assembly operation efficiency.

[0040] Specifically, in the above embodiment, the mounting plate 21 has multiple threaded holes spaced apart circumferentially along the socket body 20, and the body sheet metal 10 has multiple through holes surrounding the mounting holes 11. A connector 14, such as a bolt, passes through each through hole from the outside to the inside, and each bolt is connected to each threaded hole in a corresponding manner, thereby forming a detachable and fixed form between the mounting plate 21 and the body sheet metal 10. The advantage of this connection form is that the assembly process of the socket body 20 is always performed from the outside of the body sheet metal 10, making the operation simple and convenient.

[0041] Among some possible implementations, see [link to relevant documentation]. Figure 2 and Figure 5 The body sheet metal 10 has a limiting hole 12 on one side of the mounting hole 11 to form a first snap-fit ​​part. The second snap-fit ​​part includes a first buckle 211 and a second buckle 212 provided on the mounting plate 21. The first buckle 211 is inserted through the limiting hole 12 and snaps with the edge of the limiting hole 12 facing the mounting hole 11 to form a pre-installed connection point 22. The second buckle 212 passes through the mounting hole 11 and snaps with the edge of the mounting hole 11 away from the limiting hole 12 to form another pre-installed connection point 22.

[0042] Considering that it is more convenient to make holes on the body sheet metal 10 than to set up buckles, and that the buckle structure can be directly integrally formed on the mounting plate 21, a limiting hole 12 is set on the body sheet metal 10 as the first snap-fit ​​part, and a first buckle 211 and a second buckle 212 are set on the mounting plate 21 as the second snap-fit ​​part. During assembly, the first buckle 211 is passed through the limiting hole 12 and snapped with the edge of the limiting hole 12. This not only allows the limiting hole 12 to position the first buckle 211, but also forms pre-installed connection points 22 on both sides of the mounting hole 11 by using the snap-fit ​​between the first buckle 211 and the limiting hole 12 and the snap-fit ​​between the second buckle 212 and the edge of the mounting hole 11. This allows the mounting plate 21 to be stably snapped onto the body sheet metal 10, which facilitates the subsequent fastening operation of the mounting plate 21.

[0043] It should be noted that the first latch 211 and the second latch 212 can be arranged at an interval on the mounting plate 21, so that the two pre-installed connection points 22 are located on the front and rear sides of the socket body 20 respectively; the first latch 211 and the second latch 212 can also be arranged at an interval on the top and bottom of the mounting plate 21, so that the two pre-installed connection points 22 are located on the top and bottom sides of the socket body 20 respectively. In short, the first latch 211 and the second latch 212 can be placed on both sides of the mounting hole 11 along the radial direction of the mounting hole 11. There is no specific position limitation here, as they can both form pre-installed connection points 22 and pre-install the socket body 20.

[0044] As an optional connection method, in this embodiment, a first buckle 211 and a second buckle 212 can be provided on the body sheet metal 10, and a limiting hole 12 can be provided on the mounting plate 21 corresponding to the first buckle 211 and the second buckle 212. In this way, a pre-installed connection point 22 can be formed on the opposite sides of the socket body 20 by the engagement of the first buckle 211 and the second buckle 212 with the corresponding limiting hole 12. Therefore, the same beneficial effect as the method of opening holes in the body sheet metal 10 and setting buckles on the mounting plate 21 in the above embodiment can be obtained.

[0045] In some embodiments, see Figure 5The first buckle 211 includes a first limiting rib 2111 and a first snap connector 2112; wherein, the first limiting rib 2111 is inserted through the limiting hole 12 and has a range of motion within the limiting hole 12 to approach or move away from the mounting hole 11; the first snap connector 2112 is connected to the end of the first limiting rib 2111 away from the mounting plate 21 and bent toward the mounting hole 11, and the first snap connector 2112 is adapted to pass through the limiting hole 12 and snap onto the edge of the limiting hole 12.

[0046] The first latch 211 is L-shaped based on the first limiting rib 2111 and the bent first latching connector 2112. When the socket body 20 is pre-installed, the first latching connector 2112 passes through the limiting hole 12 and moves the socket body 20 along the surface of the body sheet metal 10 based on the amount of movement between the first limiting rib 2111 and the limiting hole 12. This causes the first latching connector 2112 to be locked at the edge of the limiting hole 12, thereby locking and positioning the socket body 20 in all directions except the reverse direction of movement. This is not only convenient to operate and suitable for blind installation, but also improves the installation position accuracy of the socket body 20. Based on the pre-installation positioning, the assembly stability of the socket body 20 is achieved through the fastening connection between the mounting plate 21 and the body sheet metal 10. When it is necessary to disassemble the socket body 20, it is only necessary to remove the fastening connection between the mounting plate 21 and the body sheet metal 10, and then move the socket body 20 in the reverse direction to allow the first latching connector 2112 to come out of the limiting hole 12. The operation is simple and convenient.

[0047] Specifically, in this embodiment, the first buckle 211 can be set in the upper edge area of ​​the mounting plate 21. The first snap-fit ​​connector 2112 is bent downward. During assembly, the first snap-fit ​​connector 2112 passes through the limiting hole 12 and hangs downward on the lower edge of the limiting hole 12. The first limiting rib 2111 is constrained by the limiting hole 12 in the front-back direction. At the same time, the first limiting member supports downward on the lower side wall of the limiting hole 12 and can be positioned in the vertical direction. The snap-fit ​​between the first snap-fit ​​connector 2112 and the edge of the limiting hole 12 can achieve limiting constraint in the left-right direction of the vehicle body. This limiting constraint is mainly to prevent the first snap-fit ​​211 from coming out of the limiting hole 12, thereby ensuring the reliability of the pre-installed connection point 22.

[0048] For example, such as Figure 6 As shown, a limiting groove 13 is provided on the edge of the mounting hole 11 away from the limiting hole 12, and the second buckle 212 is at least partially embedded in the limiting groove 13.

[0049] Setting a limiting groove 13 at the edge of the mounting hole 11 allows the second buckle 212 to be partially or entirely embedded in the limiting groove 13, thus preventing the first buckle 211 from occupying the internal space of the mounting hole 11 after assembly. On the other hand, the engagement of the second buckle 212 with the limiting groove 13 can achieve a limiting effect, thereby improving the pre-installation position accuracy of the socket body 20 in the mounting hole 11, which facilitates subsequent fastening operations and prevents the socket body 20 from being misaligned during the fastening process, thus affecting the final connection stability and sealing and waterproof performance.

[0050] For example, see Figure 6 The second buckle 212 includes a second limiting rib 2121 and a second snap connector 2122; wherein, the second limiting rib 2121 is embedded in the limiting groove 13 in the direction away from the mounting hole 11; the second snap connector 2122 is connected to the end of the second limiting rib 2121 away from the mounting plate 21 and bent away from the mounting hole 11, and the second snap connector 2122 is snapped with the edge of the limiting groove 13.

[0051] The first limiting rib 2111 and the bent second snap connector 2122 form an L-shaped second snap fastener 212. During pre-installation, the socket body 20 moves as a whole based on the movement of the first snap fastener 211 within the limiting hole 12, thereby embedding the second limiting rib 2121 into the limiting groove 13 and snapping the second snap connector 2122 onto the edge of the limiting groove 13. Based on this, the cooperation between the first snap fastener 211 and the limiting hole 12 ensures that both sides of the socket body 20 obtain stable pre-installation connection points 22. This allows the socket body 20 to be reliably pre-installed and positioned before final tightening, which not only reduces the difficulty of subsequent tightening operations and improves work efficiency, but also improves the installation position accuracy of the socket body 20, preventing the mounting plate 21 from being misaligned on the body sheet metal 10, thus affecting the tightness of the fit and leading to poor sealing.

[0052] Specifically, corresponding to the first buckle 211 being positioned above the mounting plate 21, the second buckle 212 is positioned below the mounting plate 21. The second snap-fit ​​connector 2122, like the first snap-fit ​​connector 2112, is bent downwards. This allows the first buckle 211 to be attached to the lower edge of the limiting hole 12, while the second limiting rib 2121 is embedded in the limiting groove 13 for positioning in the front-back direction. Furthermore, the second limiting rib 2121 presses downwards against the bottom of the limiting groove 13 for positioning in the vertical direction. Simultaneously, the second snap-fit ​​connector 2122... The engagement between 22 and the edge of the limiting groove 13 can prevent the second buckle 212 from disengaging from the limiting groove 13 in the width direction of the vehicle body; therefore, during pre-installation, the socket body 20 can be stably mounted on the body sheet metal 10 and fully positioned in the front and rear, width and vertical directions of the vehicle body. This ensures that the connection holes between the mounting plate 21 and the body sheet metal 10 can be accurately aligned, which facilitates subsequent fastening operations. At the same time, it can also ensure the positional accuracy of the socket body 20 after assembly, thereby avoiding the situation where the mating surface is not sealed properly due to installation deviation or misalignment.

[0053] In one possible implementation, see Figure 2 and Figure 3 The mounting plate 21 is sealed and fitted to the inner side of the body sheet metal 10. The body sheet metal 10 is provided with several connectors 14 from the outside to the inside, and each connector 14 is fastened to the mounting plate 21.

[0054] In the above technical solution, the mounting plate 21 is sealed and attached to the inner side of the body sheet metal 10, which can eliminate the step of passing the wire harness from the outside of the body sheet metal 10 through the mounting hole 11 and into the inside during assembly, thereby improving the production cycle and assembly efficiency. The mounting plate 21 is attached to the inner side of the body sheet metal 10, and the connector 14 can pass from the outside of the body sheet metal 10 inward and be fixed to the mounting plate 21. This allows the operating end of the connector 14 to be exposed and obtain a clear operating view, thereby facilitating the fastening operation of the connector 14 and further improving assembly efficiency.

[0055] Furthermore, the fact that the mounting plate 21 is attached to the inner side of the body sheet metal 10 allows only one mating seam between the edge of the mounting plate 21 and the body sheet metal 10 to exist between the socket body 20 and the body sheet metal 10 (if the mounting plate 21 is attached to the outer side of the body sheet metal 10, a seepage seam will be formed on both sides of the reinforcing sheet metal 15 on the inner side of the body sheet metal 10). Reliably sealing this mating seam can prevent water from the inner side of the body sheet metal 10 from leaking to the plug-in terminal 201 of the socket body 20, which helps to improve the vehicle's wading performance.

[0056] In some embodiments, combined with Figure 3 and Figure 4A sealing gasket 23 is sandwiched between the inner sides of the mounting plate 21 and the body sheet 10. By sandwiching the sealing gasket 23 between the mounting plate 21 and the body sheet 10, the joint between the two is sealed, thereby improving the connection sealing between the mounting plate 21 and the body sheet 10, and thus improving the waterproof performance of the socket body 20.

[0057] For example, see Figure 2 and Figure 4 The outer side of the body sheet metal 10 is attached with a reinforcing sheet metal 15. The reinforcing sheet metal 15 has a clearance hole 151 that matches the contour of the mounting hole 11, and a through hole 152 suitable for correspondingly passing through each connector 14. The reinforcing sheet metal 15 and the body sheet metal 10 together form a pre-installed connection point 22 with the mounting plate 21.

[0058] By attaching the reinforcing sheet metal 15, the structural strength of the mounting hole 11 area can be improved. At the same time, the reinforcing sheet metal 15 is provided with matching features that are exactly the same as the area of ​​the body sheet metal 10 used to connect the socket body 20. This is equivalent to forming a double-layer sheet metal structure in the mounting area of ​​the socket body 20, thereby improving the connection stability of the socket body 20 and avoiding the deformation of the body sheet metal 10 due to stress during the plugging and unplugging of the charging head.

[0059] For example, see Figure 4 The edge of the reinforced sheet metal 15 has a reinforcing folded edge 153 that is away from the body sheet metal 10. By setting the reinforcing folded edge 153, the structural rigidity of the reinforced sheet metal 15 itself can be improved, thereby improving the rigidity of the connection area between the body sheet metal 10 and the plug-in body, and avoiding problems such as poor sealing and damage to the appearance caused by the deformation of the plug-in body during the plugging and unplugging of the charging head.

[0060] Based on the same inventive concept, combined with Figures 1 to 6 It is understood that this application also provides a vehicle including the above-described charging socket mounting structure.

[0061] Compared with the prior art, the vehicle provided in this application embodiment adopts the above-mentioned charging socket installation structure. The mounting plate 21 and the body sheet metal 10 are respectively provided with a first snap-fit ​​part and a second snap-fit ​​part as pre-installation connection points 22. During the assembly operation, the first snap-fit ​​part and the second snap-fit ​​part can be snapped together first, so that the socket body 20 is pre-installed and positioned on the body sheet metal 10. Since the snap-fit ​​method is conducive to blind installation operation, it has less dependence on the operation field of vision. It can not only reduce the difficulty of assembling the socket body 20 on the body sheet metal 10 and help improve the assembly operation efficiency, but also improve the assembly position accuracy of the socket body 20 through the snap-fit ​​positioning of the first snap-fit ​​part and the second snap-fit ​​part. This can avoid the sealing problem caused by the assembly position error of the socket body 20 and reduce the difficulty of subsequent fastening connection operation, which is conducive to further improving the assembly operation efficiency.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
