Description

Technical Field

[0001] The utility model relates to a charger device, in particular to a charger lighting effect component. Background Art

[0002] New energy vehicle chargers are generally equipped with charging indicator lights, which are used to indicate the status of the charger. There are generally three states: fault, standby, and charging. Different states require different lighting effects to display.

[0003] The utility model patent with publication number CN 217099682 U discloses a high-protection charger with a charging progress display light. The charger includes an upper shell and a base that are buckled together, and a lamp board. The inner and outer sides of the upper shell are respectively provided with a boss for installing the lamp board and a groove for installing the lampshade. The boss is centrally provided with a circular array of light-transmitting holes. The lamp beads on the lamp board are arranged at intervals along the circumference to form a ring-shaped lamp group. During the charging process, the ring-shaped lamp group lights up and turns off one by one / alternately to reflect the charging progress in real time. The color of the light can be conventional white, green, red, or a color that gradually changes as the charging progresses. A surface sticker is provided between the lampshade and the groove to transform the point light source of the lamp beads into a surface area. In this solution, a boss is integrally provided on the inner side of the upper shell, and a light-transmitting hole is opened on the boss. When light passes through the light-transmitting hole, interference between the two light-transmitting holes can be avoided, but the wall of the light-transmitting hole is thick, the volume of the light-transmitting hole is small, the space for accommodating the light source is small, the light intensity is limited, and the light transmitted by the lampshade will form an obvious shadow area at the wall of the light-transmitting hole, affecting the visual effect; in addition, a lampshade is separately provided on the outer side of the upper shell to transmit light, which is easy to damage the sealing of the upper shell and reduce the protective performance of the shell. The color of the lamp beads is controlled in a single color, and transition gradient color cannot be achieved. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a charger lighting effect component that can provide eye-catching lighting effects while ensuring protective performance.

[0005] Technical solution: The utility model describes a charger lighting effect assembly, comprising a light-transmissive upper shell and an opaque inner ring rib, wherein a plurality of rib plates are arranged in the middle of the inner ring rib to form light partitions, wherein the thickness of the rib plate is not greater than 1.5 mm, an inner ring rib protrudes from the top of the rib plate, and a groove is provided on the inner side surface of the upper shell for the protruding top of the rib plate to be inserted.

[0006] In the utility model, the thickness of the rib plate of the light partition is greatly reduced, which on the one hand increases the partition volume and helps to increase the light source light passing through and the light source accommodation space, and on the other hand reduces the shadow formed by the visible rib plate of the upper shell separating the light; by increasing the height of the rib plate and inserting its top into the upper shell, not only the light leakage effect of the installation surface gap between the upper shell and the inner ring rib is eliminated, but also the light leakage caused by the light transmission of the translucent upper shell itself can be eliminated, thereby improving the visual effect of the lighting effect.

[0007] The upper shell is integrated with no dividing seams on the surface, thus ensuring the protection of internal components.

[0008] Preferably, the inner side of the upper shell is integrally formed with a hot melt column and a convex column, and the outer periphery of the inner ring rib is provided with corresponding welding holes and through holes for the hot melt column and the convex column to pass through, and the inner ring rib and the upper shell are connected by hot melting through the hot melt column and the welding hole. The inner ring rib and the upper shell are separately arranged, and the upper shell and the inner ring rib are hot melt assembled after injection molding respectively. There is no interference or constraint between the upper shell and the inner ring rib, and other reinforcement structures can be added to the inner side of the upper shell. The structure of the inner ring rib can be changed according to needs, and the whole is easy to process and convenient for mass production.

[0009] Preferably, in order to increase the strength of the upper shell and reduce injection deformation, a plurality of reinforcing ribs are integrally formed on the inner side of the upper shell.

[0011] Preferably, the partition is fan-shaped, and a ring rib plate is provided at the intersection of the rib plates to form a ring partition. The fan-shaped rib plates meet at the center of the inner ring rib, and no light passes through the intersection, which will form a lighting dead zone and affect the lighting effect. The ring rib plate is provided in the center to avoid this phenomenon.

[0012] Preferably, a pattern layer is provided outside the upper shell. The pattern layer is made of a film by screen printing, the film is pre-stamped according to the shell shape, and then injection molded to form an upper shell with a pattern.

[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0024] As shown in the figure, the charger lighting effect assembly of the utility model is mainly composed of an upper shell 1, an inner ring rib 2, and a light board 3. The upper shell 1 is a cover plate, which is generally made of transparent PC. A boss 11 and a hot melt column 12 are integrally formed on the inner side thereof. A screw hole is provided in the boss 11. The boss and the inner ring rib cooperate to support and fix the light board 3. The main body of the inner ring rib 2 is generally annular and made of opaque PC. It is installed between the upper shell 1 and the light board 3 to constrain the light of the light board 3 and form the expected light path. The outer periphery of the inner ring rib 2 is provided with corresponding mounting holes 21 for the boss 11 to pass through and hot melt holes 22 for the hot melt column 12 to pass through. After the inner ring rib 2 is installed, the hot melt column 12 and the hot melt hole 22 are hot-pressed and welded, so that the inner ring rib 2 can be fixed to the inner side of the upper shell 1.

[0025] The inner surface of the upper shell 1 has crisscrossed reinforcing ribs 14, and the height of the reinforcing ribs 14 is controlled within half of the wall thickness of the upper shell 1. The shape of the charger is generally 400×300mm. With such a large area, the installation surface of the upper shell 1 will be warped after injection molding, affecting the aesthetics of the installation, and may even lead to extreme situations where the fasteners are not centered and cannot be screwed on. Therefore, the reinforcing ribs 14 are provided to avoid thermal shrinkage and deformation defects on the upper surface of the upper shell 1.

[0026] A pattern layer is provided on the outside of the upper shell 1, and the light transmitted by the inner ring rib 2 cooperates with the pattern layer to form the expected light effect. The production process of the upper shell 1 is as follows: the pattern 16 is printed on the PET film through the silk screen printing process, and the film is hot-pressed to form a shape consistent with the outer surface of the upper shell 1, and then punched to form the pattern layer. Before the upper shell 1 is injection-molded, the pattern layer is placed in the mold and then injection-molded to form an integral part. By changing the printed pattern of the pattern layer, a light effect pattern of any color can be formed on the surface of the upper shell 1. The pattern layer is tightly and firmly combined with the plastic part of the upper shell 1 through integral injection molding, and the color effect is bright.

[0027] Several ribs 23 are arranged inside the inner ring rib 2, and the ribs 23 divide the inner ring rib 2 into several partitions. The partitions can be rectangular, fan-shaped, triangular or other shapes. Taking the fan-shaped as an example, 8 ribs 23 are arranged inside the inner ring rib 2, and the 8 ribs 23 are evenly distributed along the radial direction of the inner ring rib 2, dividing the inner ring rib 2 into 8 fan-shaped partitions of the same size. When the lamp board 3 is made, the lamp beads on the lamp board 3 are distributed in the same way as the partitions of the inner ring rib 2. For example, 16 lamp beads are arranged on the lamp board 3, and each 2 lamp beads are grouped together and distributed radially along the inner ring rib 2. The outer periphery of the lamp board 3 is provided with mounting holes 32 for screws to pass through. During assembly, the mounting holes correspond to the bosses, and the lamp beads 31 are located in the fan-shaped partition of the lamp board 3. By adjusting the distance between the two lamp beads in each partition, the most uniform light intensity distribution can be obtained. In order to prevent the display effect of the pattern area of ​​the upper shell 1 from being affected, the thickness of the strip ribs is designed to be about 1 mm, not more than 1.5 mm.

[0028] When the eight ribs converge at the circle / center of the inner ring rib 2, a dead zone of illumination will be formed at the intersection / intersection, which will affect the display effect of the pattern layer of the upper shell 1 illuminated by light. Therefore, a ring rib plate 24 connected to each rib plate 23 is set at the center of the circle of the inner ring rib 2 to form an annular partition in the fan-shaped partition. Correspondingly, a central lamp bead is set at the center of the light board 3. During assembly, the central lamp bead is located in the annular partition formed by the ring rib plate 24. When lit, light passes through the annular partition, which can avoid the center from being dark and make the light intensity distribution in the large circle more uniform. When the partition is rectangular or triangular, the same is true. Ring rib plates are added at the intersection of the rib plates 23, and corresponding lamp beads are set on the light board to avoid the formation of a dead zone of illumination.

[0029] The upper shell 1 is generally made of transparent material. When the inner ring rib 2 is assembled with the upper shell 1, the gap between the mounting surface of the upper shell 1 and the inner ring rib 2 and the light transmission of the upper shell 1 itself may cause light leakage from the partition side. In order to eliminate this effect, a concave groove 13 is added to the inner side of the upper shell 1, and the rib plate 23 is increased in height to protrude from the inner ring rib 2. During assembly, the protruding part on the top of the rib plate 23 is inserted into the groove 13. In this case, the light passing through the optical path sub-channel diffuses less when penetrating the transparent upper shell 1, effectively preventing the light from crossing the boundary between the two adjacent pattern areas of the upper shell 1.

[0030] Since the inner rib plate 2 is made of opaque material, according to the distribution of the rib plate 23 and the annular rib plate 24, the pattern layer of the upper shell 1 can be correspondingly provided with a non-pattern area 15, where no light passes, and only a light-shielding pure color (such as silver white) is printed, which does not affect the pattern display effect of the pattern area.
