[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0034] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0035] In addition, if the embodiments of the utility model involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one feature. In addition, "and / or" or "and / or" appearing throughout the text means that the three parallel schemes are included, taking "A and / or B" as an example, including A scheme, or B scheme, or A and B simultaneously meet the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0036] The display screen assembly is usually composed of three parts of a transparent panel (such as glass, etc.), a display film and a shell assembly. In order to protect the display film, a glass plate cover is usually used, but in actual application, the display film is prone to produce water mist under the environmental condition of temperature change, which affects the display effect. Most of the existing solutions adopt 3M glue to cover the back of the glass plate for overall adhesion, so as to ensure that there is no gap between the glass and the display film, and prevent the generation of water mist in the display film area. On the one hand, the cost is high, and on the other hand, the production is also more complex.

[0037] Therefore, the utility model provides a new design idea: a steam collecting groove is arranged around the edge of the electronic display screen on the surface of the shell assembly. The steam collecting groove provides a larger space, so that the water vapor is more likely to form water mist in the groove. At the same time, since the total amount of water vapor between the face cover and the glass plate is limited, the steam collecting groove is provided with an exhaust hole. In this way, when the temperature rises, the water mist in the steam collecting groove will be discharged in gaseous form from the exhaust hole, so as to solve the problem that the user cannot view the information on the display film due to the generation of water mist in the installation area of the display film.

[0038] Please refer to Figures 1 to 7 In an embodiment of the utility model, referring to Figure 1 The shell assembly includes a face cover 200. The shell assembly can constitute a display screen assembly by adding elements such as a bottom shell 100, a display film 400 and a glass plate 300, so as to provide the user with an intuitive and clear visual experience.

[0039] In the present solution, the display film 400 is an electronic film connected with the lamp plate 500 and realizing the display function on the display film 400 through electrical signals. Without loss of generality, in other solutions, the display film 400 can be a physical film such as a two-dimensional code which needs to be displayed to the user through the protective layer such as the glass plate 300.

[0040] Please refer to Figure 2 and Figure 3 The outer surface 200a of the face cover 200 has an installation area 201. The side of the face cover 200 facing the accommodating cavity 101 is an inner surface 200b. The installation area 201 is used for mounting the display film 400 of the display screen assembly. It can be understood that the face cover 200 can also have other areas outside the installation area 201.

[0041] In order to prevent the installation area 201 of the display film 400 from generating water mist, the outer surface 200a of the face cover 200 is also provided with a steam collecting groove 220 which is arranged beside the installation area 201. The arrangement beside means that the steam collecting groove 220 is arranged close to the installation area 201. Close should be understood as the range of the steam collecting groove 220 which can absorb the water vapor of the installation area 201, i.e. the steam collecting groove 220 is adjacent to the installation area.

[0042] In the embodiment, the steam pocket 220 is arranged in a loop around the mounting area 201. In other embodiments, the steam pocket 220 is discontinuously arranged around the mounting area 201; in the discontinuous arrangement, the steam pocket 220 can be arranged on any one side of the mounting area 201, or on any two, three or four sides. In the arrangement in which the steam pocket 220 is arranged around the mounting area 201, the steam pocket 220 covers the mounting area 201 in the projection direction.

[0043] The steam pocket 220 solves the problem of water mist in the display film 400 area. When the display screen assembly is suddenly lowered in temperature due to the external environment, the water vapor between the glass plate 300 and the cover 200 forms water mist. Because there is a larger space between the glass plate 300 and the cover 200 than in other areas of the cover, the temperature change in the steam pocket 220 is faster, and the water vapor between the glass plate 300 and the cover 200 will preferentially form water mist in the steam pocket 220. Because the water vapor between the glass plate 300 and the cover 200 is limited, water mist is avoided in the mounting area 201 of the display film 400, and the problem of water mist in the display area is solved. In addition, the mounting area 201 is smaller than the loop area of the steam pocket 220, so the user cannot see the water mist in the loop.

[0044] The steam pocket 220 is provided with an exhaust hole 210. When the external environment temperature rises, the water mist in the steam pocket 220 will be heated and vaporized, and the temperature on the inner surface 200b of the cover 200 is relatively lower than that on the outer surface 200a, so the vaporized water mist will be discharged from the exhaust hole 210 due to the heat transfer effect. This reduces the water vapor on the outer surface 200a and solves the problem of water mist in the mounting area of the display film due to temperature changes, which prevents the user from viewing the information on the display film.

[0045] Referring to Figure 5 In particular, the steam pocket 220 is recessed towards the bottom shell 100 side of the outer surface 200a of the cover 200. By machining the outer surface 200a of the cover 200 to be recessed towards the bottom shell 100 side, the steam pocket 220 is formed. This method is simple in process and easy to implement. By recessing to form the steam pocket 220, the use of additional structures or complex machining processes can be avoided, thereby reducing manufacturing costs and improving production efficiency. Of course, this solution is not limited thereto. When the wall thickness of the cover 200 is sufficient to form the steam pocket 220, the steam pocket 220 is formed by hollowing out the wall thickness of the cover 200.

[0046] In combination Figure 6Further, in order to reduce the cost and improve the competitiveness of the product, the face cover 200 and the glass plate 300 are bonded and fixed by a gluing process. The outer surface 200a of the face cover 200 is provided with a first blocking rib 230 and a second blocking rib 240. The second blocking rib 240 is closer to the steam collecting groove 220 than the first blocking rib 230. The first blocking rib 230 and the second blocking rib 240 define a gluing area 250. The gluing area 250 is arranged around the steam collecting groove 220. The gluing process is mainly used to firmly bond the face cover 200 and the glass plate 300 together to form a stable overall structure. The first blocking rib 230 is located on the outer surface 200a of the face cover 200 and, together with the second blocking rib 240, defines the gluing area 250. In this way, a reference surface is provided to ensure uniform distribution and appropriate use of glue during gluing.

[0047] In addition, the first blocking rib 230 and the second blocking rib 240 can also be in contact with the surface of the glass plate 300 to form a preliminary seal and limit during the gluing process. This ensures uniform distribution of glue in the gluing area 250 and prevents it from overflowing to the outside area.

[0048] However, the present scheme is not limited thereto. The gluing and bonding is mainly for the connection and sealing performance between the face cover 200 and the glass plate 300. In other schemes, the 3M glue introduced above or a combination of sealing rings can also be used to achieve connection and sealing performance.

[0049] With reference to Figure 6 Further, the second blocking rib 240 has a lower protrusion height than the first blocking rib 230. The protrusion height of the second blocking rib 240 is designed to be lower than that of the first blocking rib 230. When the glass plate 300 is placed on the face cover 200 and gluing is performed, the first blocking rib 230 plays a role in sealing and limiting, effectively preventing the glue from overflowing to the outside. The second blocking rib 240, due to its slightly lower height, when the glass plate 300 is pressed down, the glue will overflow to the inside (i.e., towards the second blocking rib 240). As the glass plate 300 continues to be pressed down, the glue is squeezed and overflows to the inside. Due to the presence of the second blocking rib 240 and its slightly lower height, the glue can flow along the inside edge of the second blocking rib 240, thereby increasing the bonding area with the glass plate 300 and the face cover 200. Although the glue will overflow to the inside, due to the blocking effect of the second blocking rib 240, the glue will not continue to overflow to the more outside area. This increases the bonding area, and the glue can better bond the glass plate 300 and the face cover 200 together, thereby improving the overall strength and durability of the display assembly. By optimizing the gluing process and reducing glue waste, the present scheme can reduce manufacturing costs and improve production efficiency. In addition, the steam collecting groove 220 can also prevent too much glue from overflowing to the mounting area 201, making the product appearance more neat and beautiful.

[0050] In combination with Figure 5Further, in order to facilitate installation, the bottom shell 100 and the face cover 200 are clamped and fixed at the four corners; in order to avoid the stress at the clamped and fixed position affecting the glue area 250, the four clamped and fixed positions define a clamped area 202, and the glue area 250 is located in the clamped area 202. When the bottom shell 100 and the face cover 200 are connected by clamping and fixing at the four corners, the stress is mainly concentrated in the clamped area 202. By setting the glue area 250 in the clamped area 202, it can be ensured that the glue area 250 will not be directly affected by the clamping stress, and the glue can be evenly distributed during the glue process, and the glue is not easy to be affected by external interference during the glue process, so as to form a more uniform and firm bonding layer.

[0051] With reference to Figure 5 and Figure 6 Specifically, a transition area 203 is further provided between the second blocking rib 240 and the steam collecting groove 220, and the transition area 203 is arc-shaped and curved from the second blocking rib 240 to the steam collecting groove 220. The arc-shaped and curved transition design makes the glue flow more smoothly during the glue process. When the glass plate 300 is pressed down, the glue is extruded and flows along the inner side of the second blocking rib 240 and the arc-shaped and curved transition area 203 until it forms a seal with the first blocking rib 230. This helps to ensure uniform distribution of the glue in the glue area 250 and avoid the situation of too much or too little glue in a local area. The transition area 203 makes the edge of the display screen assembly more smooth and fluent, improving the overall aesthetic appearance of the product.

[0052] Specifically, the face cover 200 is further provided with a limiting structure, which defines an installation area 201 for installing the display film 400; in this embodiment, the limiting structure is a limiting rib (not marked in the figure) protruding on the face cover 200, which is arranged around to form the installation area 201. In order to avoid interfering with the glue area 250, the height of the limiting rib is not higher than the height of the first blocking rib 230. In this way, the limiting rib serves as a positioning aid for installing the display film 400, which can help the installer to quickly and accurately position the display film 400.

[0053] With reference to 2 to Figure 7Further, the edge of the face cover 200 and the first blocking rib 230 are provided with a plurality of abutting ribs 260, the abutting ribs 260 protrude from the outer surface 200a of the face cover 200, the abutting ribs 260 are not higher than the first blocking rib 230, and the abutting ribs 260 are used to abut the glass plate 300 installed on the outer surface 200a of the face cover 200. Because the influence of the clamping area 202 of the face cover 200 and the bottom shell 100 is avoided, the glue area 250 is arranged in the clamping area 202, which causes the bonding area of the glass plate 300 and the face cover 200 to have a certain overhanging area from the edge of the glass plate 300. The arrangement of the abutting ribs 260 increases the support points between the face cover 200 and the glass plate 300, which helps to disperse the weight and stress of the glass plate 300, thereby enhancing the structural stability of the entire display screen assembly. The edge of the glass plate 300 can first contact the abutting ribs 260, and the abutting ribs 260 can absorb part of the impact force to reduce damage to the glass plate 300.

[0054] With reference to Figure 3 and Figure 4 Further, the face cover 200 is provided with an exhaust hole 210, which is arranged in the steam collecting groove 220 and communicates with the containing cavity 101.

[0055] When assembling the display screen assembly, the glass plate 300 is connected with the face cover 200 by the glue process. During the curing process of the glue, the glue absorbs the moisture in the air for curing. During this process, if the pressure of the space between the glass plate 300 and the face cover 200 and the external space is inconsistent, it may affect the curing effect of the glue. The arrangement of the exhaust hole 210 can make the pressure of this space consistent with the external space, thereby ensuring that the glue can be normally cured to form a firm bonding layer.

[0056] In addition, when the external environment temperature rises, the water vapor will be re-heated and evaporated. In the display screen assembly, the space of the steam collecting groove 220 is limited, and if the water vapor stays in it all the time, it may affect the performance of the assembly. Through the exhaust hole 210, the water vapor can enter the containing cavity 101 after being gaseous. Because the containing cavity 101 has a larger space, it can accommodate more water vapor and form an internal circulation. In this way, the water vapor will not stay in the steam collecting groove 220 all the time, but can circulate and evaporate in the containing cavity 101, thereby avoiding adverse effects on the assembly. The arrangement of the exhaust hole 210 helps to keep the pressure between the glass plate 300 and the display screen assembly consistent. During the working process of the display screen assembly, due to factors such as temperature change and external pressure change, there may be a difference between the internal pressure and the external pressure. If the difference is too large, it may cause excessive pressure on the glass plate 300, thereby causing it to break. Through the exhaust hole 210, the internal and external pressures can be balanced, thereby effectively preventing the glass plate 300 from breaking due to pressure changes.

[0057] In the embodiment, the steam collecting groove 220 surrounds the mounting area 201, and has an upper groove section 221 closer to the upper end of the face cover 200, and the exhaust hole 210 is arranged in the middle region of the upper groove section 221. Since the water vapor generally moves upward, arranging the exhaust hole 210 in the upper groove section 221 can conveniently discharge the collected water vapor, avoiding the accumulation of water vapor inside the assembly.

[0058] The upper groove section 221 refers to the part of the steam collecting groove 220 close to the upper end of the face cover 200. In the display screen assembly, the upper groove section 221 is usually located above the mounting area 201. It can be understood that the steam collecting groove 220 includes the upper groove section 221, a lower groove section, and two side groove sections connected to form. The middle region refers to the relatively central position in the upper groove section 221.

[0059] However, the design is not limited to this, and in some other embodiments, the position and number of the exhaust hole 210 can be reasonably arranged, such as designing the exhaust hole 210 as a concealed or decorative hole, so that it is more beautiful and practical without affecting the function.

[0060] With reference to Figure 2 and Figure 3 Specifically, the edge of the face cover 200 is provided with a retaining edge 270, which encloses and defines a cover plate area 204 on the outer surface 200a of the face cover 200 for mounting the glass plate 300, and the retaining edge 270 is flush with the surface of the glass plate 300. The cover plate area 204 enclosed by the retaining edge 270 provides a clear installation boundary for the glass plate 300, and the retaining edge 270 serves as a positioning aid when the glass plate 300 is installed, which can help the installer to quickly and accurately position the glass plate 300. This simplifies the installation steps and improves the installation efficiency. When the glass plate 300 is installed in place, the retaining edge 270 can effectively prevent it from falling off or shifting, ensuring the reliability and safety of the display screen assembly; and the design of the retaining edge 270 flush with the surface of the glass plate 300 makes the appearance of the display screen assembly more uniform and neat. This helps to improve the overall appearance of the product and enhance the user's visual experience.

[0061] With reference to Figures 1 to 7 The utility model also proposes a display screen assembly, the display screen assembly includes glass plate 300, display diaphragm 400 and shell assembly, the specific structure of this shell assembly refers to the above-mentioned embodiment, because the display screen assembly adopts all the technical schemes of the above-mentioned embodiments, therefore at least has all the beneficial effects brought by the technical scheme of the above-mentioned embodiment, here will not repeat. Among them, display diaphragm 400 and with display diaphragm 400 electricity connection's lamp plate 500, lamp plate 500 installs in accommodating cavity 101, display diaphragm 400 sets up in mounting area 201, glass plate 300 covers and sets up in the outer surface 200a of face cover 200.

[0062] Specifically, the display film 400 is electrically connected with the lamp plate 500, and both are located on the inner and outer sides of the face cover 200, that is, the display film 400 is located on the outer surface 200a side of the face cover 200, and the lamp plate 500 is located on the inner surface 200b side of the face cover 200. The display film 400 is a thin film material, which is usually composed of a substrate such as polyester film, polyimide film and conductive material such as ITO to meet the needs of different display devices. The display film 400 has a corresponding digital signal display, and the mounting area 201 is provided with a corresponding avoiding hole corresponding to the digital signal display. The display film 400 is connected with the lamp plate 500 through the avoiding hole. The bottom shell 100 and the face cover 200 are in a rectangular shape. The face cover 200 and the bottom shell 100 are combined to form a containing cavity 101 for installing electrical components. The electrical components include but are not limited to circuit boards and other electrical components.

[0063] Specifically, the display screen assembly is applied to a charging pile. The display film 400 is the core part of the display screen assembly, which is responsible for displaying key information such as charging status, power information, charging time and fault prompt. The lamp plate 500 is electrically connected with the display film 400 to provide necessary power and signal support for the display film 400. The glass plate 300 is arranged on the outer surface 200a of the face cover 200 to protect the display film 400 and the lamp plate 500 from damage from the external environment. Optionally, the glass plate 300 is made of tempered glass or other high-strength and high-transmittance materials to ensure its impact resistance and light transmission performance.

[0064] In this way, the display screen assembly can display key information such as the working status of the charging pile, the charging progress or the charging cost. Users can intuitively understand the charging situation through the display screen, so as to make corresponding operation decisions. Optionally, the display screen assembly of the charging pile can also be equipped with touch screen technology, so that users can interact with the device more conveniently.
