Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charging device. Background Art

[0002] When some charging devices, such as charging guns, are in use, they are often exposed to outdoor environments, which requires them to have good waterproof and dustproof performance. However, in order to ensure the normal exposure of the indicator light on the charging gun, light-transmitting holes must be provided on the outer shell of the charging gun for installing and accommodating the light guide component of the indicator light. Therefore, this light-transmitting hole is a position where water is likely to enter.

[0003] In the related art, generally, sealant is applied at the assembly position of the light guide component and the light-transmitting hole, or the light guide component is directly secondarily injection-molded into the light-transmitting hole of the outer shell to prevent external water vapor and dust from entering the interior of the charging gun. However, in the former solution, the life of the sealant is limited and it is very easy for the seal to fail; the latter solution requires a high process cost and complex procedures.

[0042] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0043] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0044] An embodiment of the present application provides a charging device, as Figure 1 and Figure 2 shown. The charging device includes a housing 1, an indicator light 2, a light guide member 3, and a light-transmitting member 4; a first light-transmitting opening 11 is provided on the housing 1, and the indicator light 2 is installed inside the housing 1; the light guide member 3 is located on the light-emitting side of the indicator light 2 and is fastened to the housing 1, and the light-emitting end 311 of the light guide member 3 away from the indicator light 2 exposes from the first light-transmitting opening 11 to emit at least a part of the light emitted by the indicator light 2; the light-transmitting member 4 is sleeved on the housing 1, and the orthographic projection of the light-transmitting member 4 on a set plane covers the orthographic projections of the first light-transmitting opening 11 and the light guide member 3 on the set plane, and the set plane is perpendicular to the opening direction of the first opening of the light guide member 3.

[0045] Therefore, in the charging device provided by the embodiments of the present application, a light-transmitting member 4 is further sleeved on the outer shell 1, and the light-transmitting member 4 can at least cover the setting area of the first light-transmitting opening 11 and the installation area of the light guide member 3, so that the assembly position of the light guide member 3 and the first light-transmitting opening 11 is not directly exposed to the external environment, and thus water vapor and dust in the environment are not easily introduced into the interior of the outer shell 1 from this position. Therefore, the charging device provided by the embodiments of the present application has good waterproof and dustproof performance, can prevent water vapor and dust in the external environment from entering the interior of the outer shell 1 through the assembly position of the light guide member 3 and the first light-transmitting opening 11 and eroding the electronic components of the charging device, and compared with the charging devices in the related art, in the charging device provided by the embodiments of the present application, there is no need to apply glue at the assembly position of the light guide member 3 and the outer shell 1, nor is it necessary to adopt a complex outer shell manufacturing process, which is easy to assemble and has a low assembly cost.

[0046] The charging devices provided by the embodiments of the present application are various charging devices with an indicator light 2 assembly, including but not limited to the charging gun of a new energy vehicle. To make the technical solutions and advantages of the present application clearer, hereinafter, taking this charging device as a charging gun as an example, in combination with the attached Figures 1 - 8 , the charging device provided by the embodiments of the present application will be further introduced and described.

[0047] As Figure 1 shown, in the charging device provided by the embodiments of the present application, the indicator light 2 is installed inside the outer shell 1, and the indicator light 2 can emit light, so as to play a role in prompting the user, such as prompting the user about the plugging and unplugging direction of the charging gun, etc. Optionally, the indicator light 2 may include at least one light-emitting diode (LED) integrated on a printed circuit board (PCB), or may also include at least one LED independently installed inside the outer shell 1.

[0048] The light guide member 3 is fixedly arranged on the outer shell 1, and the setting position corresponds to the installation position of the indicator light 2, so that at least a part of the light emitted by the indicator light 2 can enter from the light incident end (i.e., the end close to the indicator light 2) of the light guide member 3 and be conducted through the light guide member 3, and the light emitting end 311 (i.e., the end far from the indicator light 2) of the light guide member 3 exposes from the first light-transmitting opening 11 on the outer shell 1. Therefore, it can be realized that the light emitted by the indicator light 2 is emitted out of the outer shell 1 for the user to view. The light guide member 3 may be a light guide column made of an optical material, such as made of transparent plastic. Optionally, in addition to conducting light, the light guide member 3 can also realize the homogenization of light and minimize the light loss during the light conduction process.

[0049] It should be noted that in the embodiments of the present application, when a certain structure "appears" from the opening, it means that when a person's eye looks along the direction directly facing the opening, at least a part of the structure is located at a position where it can be seen by the person's eye. That is, it includes both the case where the structure is completely located on one side of the opening and is directly opposite to the opening, and the case where at least a part of the structure extends from one side of the opening to the other side. For example, in this embodiment, the light-emitting end 311 of the light guide member 3 can be completely located inside the housing 1, and at least a part of the light-emitting end 311 is directly opposite to the position of the first light-transmitting opening 11; alternatively, the light-emitting end 311 of the light guide member 3 can also extend through the first light-transmitting opening 11 to the outside of the housing 1.

[0050] The light-transmitting member 4 is sleeved on the outside of the housing 1 and can cover the light guide member 3 and the first light-transmitting opening 11 on the housing 1. Therefore, the light emitted from the light-emitting end 311 of the light guide member 3 can pass through the light-transmitting member 4 and be emitted for the user to view. The light-transmitting member 4 can be a light-transmitting ring made of a transparent or translucent material, for example, made of black translucent plastic. Optionally, in addition to facilitating the emission of light, the light-transmitting member 4 can also play a role in circumferentially limiting the housing 1 to achieve tightening of the housing 1 and at the same time achieve sealing with the housing 1.

[0051] In some embodiments of the present application, a second sealing member is further provided between the light-transmitting member 4 and the housing 1 to further improve the waterproof and sealing performance of the charging device. Exemplarily, the second sealing member can be a sealing ring, a gasket, etc. clamped between the light-transmitting member 4 and the housing 1, or a sealing glue coated between the housing 1 and the light-transmitting member 4.

[0052] In some embodiments of the present application, as Figure 2 shown, the light-transmitting member 4 has a portion located away from the indicator light 2 of the first light-transmitting opening 11, and along the opening direction of the first light-transmitting opening 11, there is a gap 12 between this portion of the light-transmitting member 4 and the first light-transmitting opening 11. As Figure 6 shown, this gap 12 is used to accommodate the self-locking assembly 7 and its mounting bracket 8.

[0053] In this case, the distance between the light-transmitting member 4 and the indicator light 2 is relatively far, and the optical path of the light emitted by the indicator light 2 is relatively long. If the brightness of the light emitted by the indicator light 2 is not high enough, then the indication signal seen by the user will be blurred or not obvious enough. To solve the above problems, as Figure 2 and Figure 3As shown in the figure, the light guide member 3 includes a light guide portion 31 and a lapping portion 32. The light incident end and the light emitting end 311 are located on the light guide portion 31, and the lapping portion 32 is connected to the outer peripheral wall of the light guide portion 31. When the light guide member 3 is installed in place on the housing 1 of the charging device, the light guide portion 31 passes through the first light transmissive opening 11. The light incident end of the light guide portion 31 corresponds to the position of the indicator light 2, and the light emitting end 311 is located on the side of the first light transmissive opening 11 away from the indicator light 2.

[0054] It can be seen that in this embodiment, the length of the light guide member 3 is designed to be relatively long. Its light incident end is arranged close to the indicator light 2, and it can receive more light emitted by the indicator light 2; the light is homogenized inside the light guide member 3 and is conducted to the light emitting end 311 with less light loss; the light emitting end 311 of the light guide member 3 is arranged close to the light transmissive member 4, so that the light emitted from the light emitting end 311 can pass through the light transmissive member 4 more and the brightness of the light seen by the user at the light transmissive member 4 is improved. Therefore, this solution realizes the long-distance and low-loss conduction of the light emitted by the indicator light 2 and ensures the display effect of the indicator light 2.

[0055] Optionally, the end face of the light emitting end 311 of the light guide portion 31 is designed as a frosted surface to further improve the light homogenization effect and avoid discomfort caused by direct light entering the human eye.

[0056] In addition, further considering that the light transmissive member 4 is sleeved outside the housing 1 of the charging gun, during the use of the charging gun, the light transmissive member 4 may be cracked due to the dropping or bumping of the charging gun, resulting in the failure of the seal between it and the housing 1. In this embodiment, when the light guide member 3 is installed in place on the housing 1 of the charging device, the light guide member 3 is fastened to the housing 1, and the lapping portion 32 is located on the side of the first light transmissive opening 11 away from the indicator light 2 and is hermetically lapped with the edge of the first light transmissive opening 11 facing away from the indicator light 2.

[0057] With such an arrangement, even if the seal between the light transmissive member 4 and the housing 1 fails and external water vapor and dust enter the gap 12 between the light transmissive member 4 and the first light transmissive opening 11, they cannot enter the lap joint between the lapping portion 32 and the housing 1, and thus are not likely to enter the interior of the housing 1. Therefore, it is ensured that the electronic components inside the housing 1 are not eroded and the service life of the charging device is extended. Moreover, since the light guide member 3 is directly fastened to the housing 1, it can also prevent the light guide member 3 from being displaced from the first light transmissive opening 11 when the charging device is shaken or dropped, improving the sealing reliability of the lap joint.

[0058] Optionally, as Figure 2 and Figure 3As shown, the overlapping portion 32 is a flange, and the outer diameter of the flange is greater than the diameter of the first light-transmitting opening 11. It should be understood that the distance between any position on the outer peripheral wall of the flange and the central axis of the light guide member 3 is greater than the distance between the corresponding position on the edge of the first light-transmitting opening 11 and the central axis of the light guide member 3. That is to say, the orthographic projection of the first light-transmitting opening 11 on the set plane is located within the orthographic projection of the flange on the set plane. In this way, the flange can be hermetically overlapped with the housing 1 in a surface-to-surface contact manner in the circumferential direction, thereby ensuring good sealing performance.

[0059] The shape of the flange may be the same as or different from the shape of the first light-transmitting opening 11. Exemplarily, the cross-sectional shape of the first light-transmitting opening 11 is circular, the light guide portion 31 is cylindrical, and the shape of the flange may be circular or oval.

[0060] The flange and the light guide portion 31 may be made of the same material and formed by an integral molding process; or, the flange and the light guide portion 31 may be made of different materials and connected together after being formed separately.

[0061] In some embodiments, in order to fix the light guide member 3 on the housing 1, through holes may be respectively formed at corresponding positions on the housing 1 and the flange, and then a fastener is passed through these two through holes to fix the light guide member 3 to the housing 1.

[0062] In some embodiments of the present application, as Figure 4 shown, the charging device may further include a first sealing member 5. The first sealing member 5 is sleeved on the light guide portion 31 and is located on the side of the light guide portion 31 close to the light source. When the light guide member 3 is installed in place on the housing 1, the first sealing member 5 is clamped between the overlapping portion 32 and the housing 1.

[0063] By providing the first sealing member 5 at the overlapping portion between the overlapping portion 32 and the housing 1, the sealing performance of this overlapping portion can be further improved, achieving a better waterproof and dustproof effect. Optionally, the first sealing member 5 may be a sealing ring, a gasket, etc.

[0064] In an embodiment of the present application, as Figure 5 shown, the charging device further includes a light-shielding cover 6. The light-shielding cover 6 covers the light-emitting end 311 of the light guide member 3. Wherein, a second light-transmitting opening 61 is provided on the light-shielding cover 6, and at least a part of the end face of the light-emitting end 311 of the light guide member 3 is exposed from the second light-transmitting opening 61.

[0065] The light-shielding cover 6 is used to surround the peripheral wall of the light guide member 3, only exposing at least a part of the end face of the light-emitting end 311, thereby preventing the light guide column from emitting light to the surroundings. In this way, when looking from the black semi-transparent light-transmitting member 4 into the interior of the housing 1, only the light can be seen on the end face of the light-emitting end 311 of the light guide column, and no other structures can be seen, making the overall appearance more beautiful.

[0066] In some embodiments, the light-shielding cover 6 can be made of light-absorbing rubber or silica gel material (such as black rubber / silica gel), which is wrapped outside the light-emitting end 311 of the light guide member 3 and fixed on the light guide column by friction. The light-shielding cover 6 made of this material is easy to assemble and has a low cost, but it is easy to age, and since it is only fixed by friction, it is also easy to fall off from the light guide member 3.

[0067] In other embodiments, the light-shielding cover 6 can be made of light-absorbing rigid plastic (such as black plastic), which is sleeved outside the light-emitting end 311 of the light guide member 3 and is connected to the housing 1 for fixation. Compared with the light-shielding cover 6 made of the previous material, the plastic light-shielding cover 6 has a higher service life on the basis of ensuring easy assembly and low cost, and since it is also connected to the housing 1, it is not easy to fall off and is more reliable to use.

[0068] Based on the above scheme, the light-shielding cover 6 and the housing 1 can be tightly connected. As Figure 5 shown, the bottom of the light-shielding cover 6 has a flanging, and mounting holes 62 are provided on the flanging. Through holes are also provided at the corresponding positions on the housing 1. The fasteners pass through the mounting holes 62 on the light-shielding cover 6 and the through holes on the housing 1 in sequence, and the light-shielding cover 6 can be tightly connected to the housing 1.

[0069] In some embodiments, the fixation of the light guide member 3 on the housing 1 can also be achieved by means of the light-shielding cover 6. As Figure 5 and Figure 6 shown, the light-shielding cover 6 also covers at least a part of the overlapping portion 32. When the light-shielding cover 6 is tightly connected to the housing 1 by using fasteners, the light-shielding cover 6 will simultaneously press the overlapping portion 32 tightly against the housing 1, thereby achieving the fixation of the light guide member 3 on the housing 1. In this case, since the overlapping portion 32 of the light guide member 3 does not need to be separately connected to the housing 1 by fasteners, but only needs to ensure overlapping with the housing 1, the assembly process is reduced and the assembly efficiency is improved.

[0070] Optionally, the fasteners can include at least one screw or rivet.

[0071] Some charging devices, such as charging guns, also have a self-locking component 7, which is used to lock the charging device on the power-consuming device, thereby avoiding accidental disconnection between the charging device and the power-consuming device during the power supply process, and further ensuring the power supply reliability.

[0072] In some embodiments of the present application, as Figure 6 and Figure 7 shown, the charging device further includes a self-locking component 7 and its mounting bracket 8, and the mounting bracket 8 is used to mount the self-locking component 7 on the housing 1. Among them, both the self-locking component 7 and the mounting bracket 8 are located in the space 12 between the light-transmitting member 4 and the first light-transmitting opening 11, and the mounting bracket 8 is fixedly connected to the housing 1, and the fixing method can be selected according to actual needs, such as fixing with screws.

[0073] Exemplarily, the self-locking component 7 can adopt a common self-locking structure in the art, such as a self-locking hook. The rod portion of the self-locking hook is generally relatively long so that its hook portion can extend out from one side of the housing 1 to engage with the corresponding buckle position on the electrical device.

[0074] During the installation and arrangement of the self-locking component 7 and the mounting bracket 8, interference may occur with the light guide member 3, affecting the emission of light. Therefore, in the embodiments of the present application, light-transmitting openings can be opened on the components that will interfere with the light guide member 3 to ensure the smooth emission of light. Exemplarily, as Figure 6 and Figure 7 shown, both the self-locking component 7 and the mounting bracket 8 have portions located in the opening direction of the first light-transmitting opening 11. Therefore, a third light-transmitting opening 71 can be provided on the self-locking component 7, and a fourth light-transmitting opening 81 can be provided on the mounting bracket 8. The positions of the third light-transmitting opening 71 and the fourth light-transmitting opening 81 correspond to the position of the first light-transmitting opening 11. In this way, the light guide portion 31 can sequentially pass through the first light-transmitting opening 11, the fourth light-transmitting opening 81, and the third light-transmitting opening 71, so that the light-emitting end 311 is located close to the light-transmitting member 4, thereby ensuring the display effect.

[0075] Correspondingly, the light-shielding cover 6 covering the light-emitting end 311 of the light guide member 3 at least penetrates through the third light-transmitting opening 71 to ensure the anti-overflow light effect. Among them, since the self-locking component 7 needs to generate displacement when locking and unlocking, the diameter of the third light-transmitting opening 71 can be designed to be slightly larger, so that both the light guide portion 31 and the light-shielding cover 6 are in clearance fit with the self-locking component 7 to reserve the movement space for the self-locking component 7.

[0076] In some embodiments of the present application, referring to Figure 8 , the orthographic projections of the overlapping portion 32 and the first seal 5 on the set plane are located within the orthographic projection of the fourth light-transmitting opening 81 on the set plane; the orthographic projection of the light-shielding cover 6 on the set plane overlaps with the orthographic projection of the fourth light-transmitting opening 81 on the set plane. That is to say, the overlapping portion 32 and the first seal 5 of the light guide member 3 are both accommodated inside the fourth light-transmitting opening 81, while the light-shielding cover 6 is located above the fourth light-transmitting opening 81 and overlaps with the mounting bracket 8, thereby forming another seal.

[0077] Thus, even if the light-transmitting member 4 is broken, or the seal between the light-transmitting member 4 and the housing 1 fails, causing external water vapor and dust to enter the space 12 between the light-transmitting member 4 and the first light-transmitting opening 11, the water vapor and dust still need to first pass through the contact surface between the light-shielding cover 6 and the mounting bracket 8, and then through the contact surface between the overlapping portion 32 of the light guide member 3 and the first seal 5, or the contact surface between the first seal 5 and the housing 1, before entering the interior of the housing 1. Therefore, the path length and the difficulty of entry of external water vapor and dust into the interior of the housing 1 are greatly increased, making the waterproof and dustproof performance of the charging device more excellent and reliable.

[0078] In this case, since the mounting bracket 8 is fixedly connected to the housing 1, the light-shielding cover 6 stacked on the mounting bracket 8 can be directly fastened to the mounting bracket 8 by fasteners, thereby reducing the assembly difficulty of the light-shielding cover 6.

[0079] Alternatively, the fastener can also pass through the light-shielding cover 6 and the mounting bracket 8 in sequence, thereby fastening both of them to the housing 1 at the same time. In this way, there is no need to separately fix the mounting bracket 8 to the housing 1, reducing the number of assembly parts and assembly steps, and improving the assembly efficiency.

[0080] Alternatively, one fastener is used to separately fix the mounting bracket 8 to the housing 1, and another fastener passes through the light-shielding cover 6 and the mounting bracket 8 to fix both of them to the housing 1 at the same time. This solution can ensure a more reliable fixing effect.

[0081] In summary, the charging device provided by the embodiment of the present application can use the light guide member 3 to achieve long-distance and low-loss conduction of the light emitted by the indicator lamp 2 from the interior of the housing 1 to the exterior, ensuring the display effect. Moreover, the overlapping portion 32 of the light guide member 3 and the housing 1 is sealed at the first level by the first seal 5, the light-shielding cover 6 and the mounting bracket 8 are stacked on each other for secondary sealing, and a second seal can be provided between the housing 1 and the light-transmitting member 4 for tertiary sealing.
