Description
Technical Field
[0001] The utility model relates to the technical field of visual display devices for charging piles, and particularly relates to a power display for a charging pile. Background Art
[0002] With the popularization of electric vehicles and the continuous increase in the global demand for renewable energy, the development of the new energy industry has become increasingly remarkable. As a key supporting facility, the visual management and monitoring of charging piles are particularly important.
[0003] Most existing charging piles adopt traditional display modes such as display screens. Users judge various parameters during charging through the display screen, such as charging time, charging power, etc. Most traditional charging pile displays use LCD screens, but LCD screens have high energy consumption, and their visibility is very low in strong light environments or at long distances, making it impossible to accurately and timely obtain various charging parameter data, which affects the actual experience. Summary of the Utility Model
[0004] In view of the deficiencies in the prior art, the utility model provides a power display for a charging pile, which solves the problem that the LCD screen used in existing charging piles to display charging parameter data has very low visibility in strong light environments or at long distances.
[0005] According to an embodiment of the utility model, a power display for a charging pile includes an installation box, a light-limiting strip, a light-shielding device, and an LED lamp. An installation opening is provided on the front side of the installation box, and the light-limiting strip is installed in the installation opening. A strip-shaped light hole is vertically opened in the middle of the light-limiting strip. The LED lamp is installed in the installation box, and the light-shielding device is arranged at the rear side of the light-limiting strip for partially shielding the strip-shaped light hole.
[0006] Preferably, the light-shielding device includes a winding mechanism and two soft strips. Both ends of the two soft strips are respectively fixedly connected to the two winding mechanisms, and a light-shielding film is fixedly arranged between the two soft strips.
[0007] Preferably, the winding mechanism includes a rotating shaft and a servo motor. The rotating shaft is coaxially and fixedly connected to the output end of the servo motor, and the end of the soft strip is fixedly connected to the rotating shaft.
[0008] Preferably, a laser emitter is arranged on the upper side inside the installation box, and a through hole is provided at the upper end of the front side of the installation box and is on the same horizontal plane as the laser emitter.
[0009] Preferably, two limiting strips are symmetrically and vertically arranged at the rear side of the light-limiting strip. The cross-section of the limiting strip is L-shaped, and the two soft strips respectively abut against the two limiting strips.
[0010] Preferably, a glass sheet is installed in the strip-shaped light hole, and scale lines are drawn on the light-limiting strip beside the strip-shaped light hole.
[0011] Preferably, a condenser lens is also installed in the installation box, and the LED lamp is installed at the exact center of the condenser lens.
[0012] Compared with the prior art, the present utility model has the following beneficial effects:
[0013] The light-limiting strip is irradiated by the LED lamp, and the range of the strip-shaped light hole covered by the light-shielding device is adjusted according to the remaining power of the charging pile. The light of the LED lamp is emitted from the part not covered by the light-shielding device, forming a light strip. The length of the light strip represents the charging amount, thus replacing the LCD screen. The visual effect is more intuitive, the display effect is better, and the situation of low visibility is avoided. Description of the Drawings

[0019] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.
[0020] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a power display for a charging pile, including an installation box, a light-limiting strip 5, a light-shielding device, and an LED lamp 6. A plurality of installation openings are provided on the front side of the installation box, and the light-limiting strip 5 is installed in each installation opening. A strip-shaped light hole 1 is vertically opened in the middle of the light-limiting strip 5. A glass sheet is installed in the strip-shaped light hole 1 to prevent external dust and other sundries from entering the installation box. Scale lines are drawn on the light-limiting strip 5 beside the strip-shaped light hole 1. The LED lamp 6 is installed in the installation box, and the light-shielding device is arranged at the rear side of the light-limiting strip 5 for partially covering the strip-shaped light hole 1.
[0021] According to the remaining power of the charging pile, the shutter blocks the strip light hole 1 from top to bottom, and the LED light 6 directly shines on the strip light hole 1, and is emitted from the part not blocked by the shutter. From the outside of the charging pile, a light strip is formed. The user can accurately know the charging amount according to the length of the light strip and the indication of the scale line, which replaces the LCD screen. The visual effect is more intuitive and the display effect is better, avoiding the situation of low visibility.
[0022] In addition, similar light bar lengths can also be used to determine other parameter data such as remaining charging time, remaining power of the charging pile, etc., not limited to the charging amount.
[0023] like Figure 4 As shown, the sunshade includes a winding mechanism and two soft strips 8 made of silicone, both ends of the two soft strips 8 are fixedly connected to the two winding mechanisms respectively, a shading film 9 is fixedly provided between the two soft strips 8, and the length of the shading film 9 is only half of the soft strip 8, the winding mechanism includes a rotating shaft 3 and a servo motor, the rotating shaft 3 is coaxially fixedly connected to the output end of the servo motor, and the end of the soft strip 8 is fixedly connected to the rotating shaft 3.
[0024] According to data such as the charging amount and charging time, the angle corresponding to the forward / reverse rotation of the servo motor drives the soft strip 8 to move up and down, thereby driving the shading film 9 to move up and down, blocking the strip light hole 1 from top to bottom. Since the length of the shading film 9 is only half of the soft strip 8, when the strip light hole 1 is completely shielded / unshielded, the soft strip 8 is no longer wrapped around the rotating shaft 3 located on the upper side / lower side of the light-limiting strip 5.
[0025] like Figure 3 As shown, two limiting strips 7 are symmetrically and vertically arranged on the rear side of the light limiting strip 5 . The cross section of the limiting strip 7 is L-shaped, and the two soft strips 8 are respectively in conflict with the two limiting strips 7 .
[0026] The light-limiting strip 5 and the limiting strip 7 cooperate with each other to form a mutually symmetrical U-shaped groove. The cross-sections of the two soft strips 8 are also rectangular that cooperate with the U-shaped groove and are respectively embedded in the U-shaped groove, and move up and down with the rotation of the rotating shaft 3. At the same time, the shading film 9 can always be closely attached to the rear side of the light-limiting strip 5 to avoid a large amount of light leakage, which leads to irregularities in the light strip and difficulty in reading.
[0027] A laser emitter 2 is arranged on the upper side of the installation box, a through hole is arranged on the upper front end of the installation box and is located at the same level as the laser emitter 2, and a glass sheet is also arranged in the through hole to prevent external dust and other debris from entering.
[0028] The laser emitter 2 emits laser light, which passes through the through-hole. When an obstacle appears within the laser path range (generally, the detection range of the laser emitter 2 is set to 1 meter, and generally, a person is in front of the display), the LED lamp 6 will light up. When the LED lamp 6 is lit and the laser emitter 2 does not detect an obstacle for a long time (generally set to 1 minute), the LED lamp 6 will automatically turn off to avoid wasting a large amount of power due to the LED lamp 6 staying on constantly.
[0029] A condenser lens 4 is also installed in the installation box, and the LED lamp 6 is installed at the exact center of the condenser lens 4. The condenser lens 4 is used to concentrate the light of the LED lamp 6 and direct it towards the light-limiting strip 5, enhancing the visibility of the light strip formed through the strip-shaped light hole 1.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
