Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a diffused light structure for a DC charging pile light display. Background Technology

[0002] With the increasing popularity of electric vehicles, charging stations, as an important supporting facility, must not only meet basic charging functions but also consider aesthetics and user experience in their design. Currently, charging stations use exposed light guide plates as decorative elements, using the light emitted from the light guide plate to enhance the overall aesthetics. However, in existing technologies, the light from the light guide plate is displayed by directly embedding LED beads in the cover. The sides of the light guide plate are flat, and the light emitted by the LED beads propagates through the light guide plate, directly passing through the reflector. The light emission effect of the light guide plate is mostly strip-shaped, lacking variation and a sense of layering, resulting in a relatively monotonous visual effect and low brightness.

[0003] Chinese Patent No. CN202421361958.9 discloses a diffused light structure for a DC charging pile light display, wherein screws are used to connect the decorative ring and the cover, the decorative ring and the light guide plate, the cover and the light guide plate, and the light guide plate and the bottom shell.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0005] Because the light guide plate is easily affected by stains and is a consumable part, it needs to be replaced or the stains need to be treated after it is damaged or stained. When connecting multiple plates of the diffused light structure, multiple screws are required, which greatly increases the difficulty of disassembly.

[0006] Therefore, providing a DC charging pile lighting display diffuser structure that facilitates the disassembly of multiple panels of the diffuser structure is a problem that this utility model urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the shortcomings of existing technologies where the light guide plate is easily affected by stains and is considered a consumable part. After damage or staining, it requires replacement or treatment. Furthermore, connecting multiple sections of the diffused light structure requires multiple screws, significantly increasing the difficulty of disassembly. Therefore, this invention provides a DC charging pile lighting display diffused light structure that facilitates the disassembly of multiple sections of the diffused light structure.

[0008] To achieve the above objectives, this utility model provides a DC charging pile lighting display diffused light structure, which includes: a face cover, an optical tooth light guide strip, a bottom shell, and a quick-release assembly. The face cover, optical tooth light guide strip, and bottom shell are connected sequentially from top to bottom via the quick-release assembly. The quick-release assembly includes: a fixing base, elastic snap-fit ​​pieces, snap-fit ​​posts, and a locking element. The fixing base has elastic snap-fit ​​pieces on opposite sides, and one end of the snap-fit ​​post is adapted to each elastic snap-fit ​​piece, while the other end is provided with a locking element.

[0009] Preferably, a decorative cover adapted to the face cover is also provided above the face cover via a quick-release assembly.

[0010] Preferably, the locking post has a limiting groove on each side opposite to the locking member at the end away from the locking member.

[0011] Preferably, the locking element is a nut, and a washer is also fitted between the nut and the bottom shell.

[0012] Preferably, the locking element is a lever, one end of which is rotatably disposed off-center from its axis at the end of the locking post away from the limiting groove.

[0013] Preferably, a snap-fit ​​block is provided on one side of the twisting mechanism, and snap-fit ​​parts are provided on opposite sides of the snap-fit ​​block. A snap-fit ​​frame is provided on one side of the bottom shell, and snap-fit ​​grooves adapted to the snap-fit ​​parts are provided on opposite inner sides of the snap-fit ​​frame.

[0014] Preferably, the cover has a light-transmitting area, and an LED light panel is provided at the bottom of the optical tooth light guide strip near the light-transmitting area. The side of the LED light panel away from the optical tooth light guide strip is also provided with black opaque adhesive.

[0015] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application achieves a snap-fit ​​by setting the fixing base inside the decorative cover, and then passing the snap-fit ​​post through the bottom shell, optical tooth light guide strip, face cover, inner side of the decorative cover, and each elastic snap-fit ​​piece. Since the other end of the snap-fit ​​post is provided with a locking member, the decorative cover, face cover, optical tooth light guide strip, and bottom shell can be fixed by the two ends of the snap-fit ​​post. When disassembling, it is only necessary to rotate the locking member to drive the other end of the snap-fit ​​post to rotate to the gap of each elastic snap-fit ​​piece, so that the other end of the snap-fit ​​post is no longer engaged with each elastic snap-fit ​​piece, thereby facilitating the user to remove the decorative cover, face cover, optical tooth light guide strip, and bottom shell.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] Reference Figure 3 and Figure 4 A diffused light display structure for a DC charging pile includes: a face cover 1, an optical tooth light guide strip 4, a bottom shell 7, and a quick-release assembly 8. The face cover 1, the optical tooth light guide strip 4, and the bottom shell 7 are connected sequentially from top to bottom via the quick-release assembly 8. The quick-release assembly 8 includes: a fixing base 801, elastic snap-fit ​​pieces 802, snap-fit ​​posts 803, and a locking element 804. The fixing base 801 has elastic snap-fit ​​pieces 802 on opposite sides. One end of the snap-fit ​​post 803 is adapted to each elastic snap-fit ​​piece 802, and the other end is provided with a locking element 804.

[0030] Reference Figure 1 and Figure 3 A decorative cover 6, adapted to the surface cover 1, is also provided above it via a quick-release assembly 8.

[0031] This application achieves a snap-fit ​​connection by placing the fixing base 801 inside the decorative cover 6, and then passing the snap-fit ​​post 803 through the bottom shell 7, the optical tooth light guide strip 4, the face cover 1, the inner side of the decorative cover 6, and each elastic snap-fit ​​piece 802. Since the other end of the snap-fit ​​post 803 is provided with a locking member 804, the decorative cover 6, the face cover 1, the optical tooth light guide strip 4, and the bottom shell 7 can be fixed by the two ends of the snap-fit ​​post 803. When disassembling, it is only necessary to rotate the locking member 804 to drive the other end of the snap-fit ​​post 803 to the gap of each elastic snap-fit ​​piece 802, so that the other end of the snap-fit ​​post 803 is no longer engaged with each elastic snap-fit ​​piece 802, thereby making it easy for the user to remove the decorative cover 6, the face cover 1, the optical tooth light guide strip 4, and the bottom shell 7. The decorative cover 6 can cover the fixing base 801 and the elastic snap-fit ​​pieces 802 to improve the aesthetics of the entire device.

[0032] Reference Figure 5 and Figure 6 The locking post 803 has a limiting groove 80301 on each side opposite to the locking member 804 at the end away from the locking member 804.

[0033] In this application, each elastic snap-fit ​​piece 802 is snapped into the limiting groove 80301 to achieve snap-fit, and then the locking member 804 is rotated to drive each elastic snap-fit ​​piece 802 to disengage from the limiting groove 80301, thereby achieving quick release.

[0034] Reference Figure 3 and Figure 5 The locking component 804 is a nut, and a washer 805 is also fitted between the nut and the bottom shell 7.

[0035] This application uses a gasket 805 to compress the elastic snap-fit ​​piece 802 through the limiting groove 80301, as shown in the figure. The more the elastic snap-fit ​​piece 802 is compressed, the better the fixing effect on the decorative cover 6, the face cover 1, the optical tooth light guide strip 4, and the bottom shell 7. At the same time, the user can turn the nut with a screwdriver or other tools to make the elastic snap-fit ​​piece 802 disengage from the limiting groove 80301, thereby achieving quick release.

[0036] Reference Figure 4 and Figure 6 The locking element 804 is a lever, one end of which is rotatably disposed off-center from its axis at the end of the locking post 803 away from the limiting groove 80301.

[0037] In this application, the lever is rotatably positioned off-axis at the end of the locking post 803 away from the limiting groove 80301. By rotating the lever, each elastic locking piece 802 can be compressed through the locking post 803, improving the fixing effect on the decorative cover 6, face cover 1, optical tooth light guide strip 4, and bottom shell 7. Then, the lever will be fixed to the bottom shell 7 by friction. During disassembly, by rotating the lever, each elastic locking piece 802 is restored, and then by rotating the lever, the locking post 803 is rotated, thereby causing the elastic locking piece 802 to disengage from the limiting groove 80301, achieving quick disassembly.

[0038] Reference Figure 4 The twisting side is provided with a snap-fit ​​block 806, and snap-fit ​​parts are provided on the opposite sides of the snap-fit ​​block 806. The bottom shell 7 is provided with a snap-fit ​​bracket 701 on one side, and the snap-fit ​​bracket 701 is provided with snap-fit ​​grooves that are adapted to the snap-fit ​​parts on the opposite two inner sides.

[0039] When the lever is fixed to the bottom shell 7 by friction, the snap-fit ​​block 806 can be snapped into the snap-fit ​​grooves on the two inner sides of the snap-fit ​​bracket 701 by the snap-fit ​​pieces on both sides, so as to prevent the lever from rotating and also to prevent the snap-fit ​​post 803 from rotating, thus improving the fixing effect. When removing, simply rotate the lever to turn the snap-fit ​​block 806 out of the snap-fit ​​bracket 701, and then rotate the lever to drive the snap-fit ​​post 803 to rotate, so that the elastic snap-fit ​​piece 802 is disengaged from the limiting groove 80301, achieving quick removal without the need for additional tools.

[0040] Reference Figure 1 and Figure 2 The cover 1 has a light-transmitting area 2. The bottom of the optical tooth light guide strip 4 near the light-transmitting area 2 has an LED light board. The side of the LED light board 5 away from the optical tooth light guide strip 4 also has a black opaque adhesive backing 3.

[0041] The light-transmitting area 2 of this application is set in a specific area of ​​the face cover 1, such as the charging status indicator, fault indicator, connection confirmation, etc. When the light is on, it indicates that the device is in a charging state or other state.

[0042] The optical tooth light guide strip 4 is made of a material with high light transmittance and low scattering, commonly acrylic sheet or optical grade PC material. It mainly uses the optical teeth / dot design on the inner surface to actively scatter light, break the total internal reflection path of light, and force the light to diffuse evenly inside the light guide strip, illuminating the entire light-transmitting area 2.

[0043] The LED light panel 5 is mainly connected to the main control system of the charging pile to receive the light-on / off command, and the light color can also be changed to represent the different states of the charging pile.

[0044] The black opaque adhesive 3 fundamentally prevents the light emitted by the LED light panel 5 from leaking into the space behind the light panel, thereby preventing stray light, cloudy and unclear display effects, and other problems.

[0045] In use, the device provided by this utility model involves placing the fixing base 801 inside the decorative cover 6, and then using the snap-fit ​​post 803 to pass through the bottom shell 7, the optical tooth light guide strip 4, the face cover 1, the inner side of the decorative cover 6, and each elastic snap-fit ​​piece 802 to achieve snap-fit. Since the other end of the snap-fit ​​post 803 is provided with a locking member 804, the decorative cover 6, the face cover 1, the optical tooth light guide strip 4, and the bottom shell 7 can be fixed by the two ends of the snap-fit ​​post 803. When disassembling, it is only necessary to rotate the locking member 804 to rotate the other end of the snap-fit ​​post 803 to the gap of each elastic snap-fit ​​piece 802, so that the other end of the snap-fit ​​post 803 is no longer engaged with each elastic snap-fit ​​piece 802, thereby facilitating the user to remove the decorative cover 6, the face cover 1, the optical tooth light guide strip 4, and the bottom shell 7. The decorative cover 6 can cover the fixing base 801 and the elastic snap-fit ​​pieces 802 to improve the aesthetics of the entire device.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0048] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
