[0050] Below, with reference to the drawings, the panel assembly 1 according to the first aspect of the present application is described. It can be understood that the panel assembly 1 can be used in electrical appliances with display function, such as air conditioners, air purifiers, etc., in the following description of the present application, the panel assembly 1 is used in air conditioner as an example, and those skilled in the art can easily understand the embodiments of the panel assembly 1 used in other types of electrical appliances after reading the following description.

[0051] AsFigures 1-6 As shown, according to the panel assembly 1 of the first aspect of the present application, the panel assembly 1 comprises a display panel 10 and a display module 20, a recess 14 is formed on the front side of the display panel 10, the recess 14 is extended as an open ring or a closed ring to separate the display panel 10 into a main body area 11, a first area 12 and a second area 13, the main body area 11 is located at the outer circumferential side of the recess 14, the first area 12 corresponds to the bottom wall of the recess 14, and the second area 13 is located at the inner side of the recess 14, and the second area 13 is configured as a light-transmitting display area, the display module 20 is arranged at the back side of the display panel 10, and the display module 20 comprises a circuit board 22 and an expression display unit 24 arranged on the circuit board 22, the expression display unit 24 is used to display expression symbols, and the expression display unit 24 is opposite to the second area 13.

[0052] As can be seen, the recess 14 is formed on the front side of the display panel 10, the recess 14 is an open ring or a closed ring, so that the recess 14 can present a profile similar to a face, adding a three-dimensional effect to the display panel 10, so that the entire panel assembly 1 looks more three-dimensional and lively; the second area 13 is located at the inner side of the recess 14 and the second area 13 is configured as a light-transmitting display area, so that the expression display unit 24 can display different expression symbols through the second area 13; thus, by forming the profile of the face through the recess 14 and displaying different expression information through the expression display unit 24, an effect similar to a human facial expression is formed on the display panel 10, the interestingness of the display panel 10 is enhanced, the display content on the display panel 10 is more diversified, and a more diversified use experience is provided for users.

[0053] It can be understood that the front side of the display panel 10 can be understood as the side of the display panel 10 facing the user during use, and the back side of the display panel 10 can be understood as the side of the display panel 10 facing away from the user during use; in addition, the expression symbols displayed by the expression display unit 24 through the second area 13 can be dynamic or static, and can be selected and switched according to the needs of the user.

[0054] In addition, the recess 14 is formed on the front side of the display panel 10, the recess 14 is an open ring or a closed ring, so that the recess 14 presents a profile similar to a face, compared with using another separate component such as a display unit (such as an LED lamp, an OLED pixel, etc.) on the display panel to simulate the profile of the face, the present application can reduce the amount of display units on the display panel 10, reduce the number of components of the panel assembly 1, reduce the manufacturing cost of the panel assembly 1, and reduce the energy consumption of the panel assembly 1 during operation, and at the same time, the recess 14 as the profile of the face, the processing of the recess 14 is relatively simple and easy to implement.

[0055] Compared with some technologies, the display module is a simple LED indicator light or a monochrome liquid crystal display screen, which can meet the basic function prompt and information display of the panel assembly, but the display content and visual experience are relatively single. According to the panel assembly 1 in the embodiment of the utility model, the expression display unit 24 displays the expression symbol through the second area 12, so that the information displayed on the panel assembly 1 can be more diversified, and the user can more intuitively understand the various state information of the air conditioner. Moreover, cooperating with the groove 14 on the front side of the display panel 1, the groove 14 can cooperate with the expression symbol of the expression display unit 24, so that the groove 14 can be used as the outline of the face of the expression symbol, so that the expression information displayed by the panel assembly 1 is more three-dimensional, obvious and vivid, which is convenient for the user to quickly identify. Moreover, the panel assembly 1 has simple structure and low cost.

[0056] It should be noted that the "annular" described herein is understood in a broad sense, that is, not limited to "circular ring", for example, it can also be "polygonal ring" and the like; in addition, the "annular" includes open annular (that is, non-closed annular, such as C-shaped, U-shaped, Ω-shaped, etc.) and closed annular.

[0057] As shown in Figures 1-6 In some embodiments, the first area 12 is configured to satisfy at least one of the following conditions A1-A3:

[0058] In condition A1, the inner edge of the first area 12 is circular, elliptical, or polygonal, and the outer edge of the first area 12 is circular, elliptical, or polygonal. Among them, the polygon can be a triangle, a quadrilateral (such as a rectangle, a square, a rhombus, etc.), a pentagon, a hexagon or a polygon with more sides.

[0059] It can be seen that the inner edge and the outer edge of the first area 12 are regular shapes, and the regular shapes make the processing process more standardized and streamlined, and the processing equipment can be more easily adapted and positioned, reducing the processing difficulty and thus improving the processing efficiency. For example, when using laser cutting or mechanical stamping process, the regular shape is easier to achieve accurate cutting, reducing the processing error.

[0060] In addition, the regular-shaped first area 12 can better coordinate with other parts of the display panel 10, improving the overall display effect. It can be understood that the inner edge and the outer edge of the first area 12 can be the same or different, so that the design of the first area 12 is more flexible, facilitating the improvement of the aesthetics and recognition of the panel assembly 1.

[0061] In condition A2, the shape of the inner edge of the first area 12 is the same as the shape of the outer edge, when the inner edge and the outer edge shape are the same, the number of mold replacement and adjustment during the processing of the first area 12 can be reduced, thereby reducing the production cost, and at the same time, due to the consistency of the shape, the automatic production can be more easily realized, the production efficiency is improved, and when the inner edge and the outer edge shape of the first area 12 are the same, the visual harmony and beauty can be more easily realized, a visual continuity and consistency can be created, which helps to reduce visual interference and confusion, so that the user can focus more on the display content, and the market competitiveness of the panel assembly 1 can be improved.

[0062] In condition A3, the first area 12 is arc-shaped, and the central angle of the arc is greater than or equal to 180°, so that the shape of the groove 14 is also arc-shaped, and the profile of the arc can naturally simulate the curve of the face, thereby enhancing the three-dimensional effect of the display panel 10, when the central angle of the arc is greater than or equal to 180°, the groove 14 can naturally form a face profile, and the second area 13 is located in the face profile of the arc, so that the display content on the second area 13 is more prominent, and the visual effect is improved. It can be understood that the first area 12 can also be other shapes to meet the different use experience of the user.

[0063] As shown in Figures 1-6 In some embodiments, the first area 12 satisfies condition A2, the inner edge and the outer edge of the first area 12 are both circular, and the center of the inner edge and the center of the outer edge of the first area 12 are spaced apart in a direction perpendicular to the thickness direction of the display panel 10.

[0064] It can be seen that the inner edge and the outer edge of the first area 12 are both circular, so the user can design and manufacture the mold according to the parameters of the circle (such as radius, center distance, etc.), without considering complex shape changes, thereby reducing the manufacturing cost and period of the mold, and the circular design has a simple and smooth beauty, so that the first area 12 is more harmonious and beautiful in vision. The center of the inner edge and the center of the outer edge of the first area 12 are spaced apart in a direction perpendicular to the thickness direction of the display panel 10, so that the width of the first area 12 (i.e. the width of the groove 14) gradually changes along the circumferential direction, and a certain level of visual experience can be formed.

[0065] In other embodiments of the present application, the center of the inner edge and the center of the outer edge of the first area 12 are located on the same straight line extending along the thickness direction of the display panel 10, that is, the orthographic projection of the center of the inner edge and the center of the outer edge of the first area 12 on the display panel 10 in the thickness direction is located at the same point, which is convenient for simplifying the structure of the groove 14 and facilitating processing, and at this time the width of the groove 14 can be constant along the circumferential direction.

[0066] As shown in Figures 4-6As shown, in some embodiments, the first region 12 is also configured as a light-transmitting display region, and the display module 20 further includes a light-up display unit 240 disposed on the circuit board 22, the light-up display unit 240 being opposite to the first region 12.

[0067] As can be seen, the first area 12 also constitutes a light-transmitting display area, and the light-up display unit 240 is arranged opposite to the first area 12. Thus, the light-up display unit 240 can be displayed through the first area 12, making the face-like outline formed by the groove 14 more prominent, which is convenient for identification and enhances visual recognition.

[0068] Furthermore, since the first region 12 is the bottom wall of the groove 14, the two side walls of the groove 14 can serve as guides for light. When light passes through the first region 12 (i.e., the bottom wall of the groove 14), the two side walls can, to some extent, help the light to be distributed more evenly throughout the first region 12, reducing light scattering and thus improving the clarity and brightness of the display effect.

[0069] like Figures 4-6 As shown, in some embodiments, the thickness of the first region 12 is less than the thickness of the second region 13, and the thickness of the second region 13 is less than the thickness of the main region 11.

[0070] It can be seen that the thickness of the first region 12 (e.g.) Figure 5 The thickness of L2 in the middle and the second region 13 (e.g., L2 in the middle) and the thickness of the second region 13 (e.g., L2 in the middle) Figure 5 In the L3) all are smaller than the thickness of the main body region 1111 (e.g. Figure 5 In the L5 section, the light-up display unit 240 is opposite to the first area 12, and the expression display units 24 are opposite to the second area 13. The relative arrangement allows light to accurately pass through the corresponding display areas for display. The display information of the expression display unit 24 can be displayed from the back side of the display panel 10 through the second area 13, and the display information of the light-up display unit 240 can be displayed from the back side of the display panel 10 through the first area 12. This allows users located on the front side of the display panel 10 to read the display information of the light-up display unit 240 and the expression display unit 24, thereby improving the accuracy and readability of the display. In addition, the thinner first area 12 and second area 13 can reduce the attenuation of light during the transmission process, improve the light transmission efficiency, and make the display on the panel assembly 1 clearer and brighter.

[0071] Optionally, the light-transmitting display region can be made of a light-transmitting material at a corresponding position of the structure, for example, the entire display panel 10 is made of a material with a relatively high light-transmitting rate, the surface of the main region 11 can be coated with a light-blocking layer, and the light-transmitting display region is not coated with a light-blocking layer. At this time, the thicknesses of the main region 11, the first region 12, and the second region 13 can be equal or not equal; for another example, the thickness of the light-transmitting display region is less than the thickness of the main region 11, so as to improve the light-transmitting rate of the light-transmitting display region by reducing the thickness.

[0072] In some embodiments, the thicknesses of the main region 11 and the second region 13 are equal, the back side of the main region 11 is coated with light-blocking paint, and the first region 12 and the second region 13 are not coated with light-blocking paint. Then, the lighted display can be displayed through the first region 12, and the expression display unit 24 can be displayed through the second region 13. The thicknesses of the main region 11 and the second region 13 are the same, so that the panel assembly 1 is easier to realize standardization and automation in the processing process, which helps to improve the production efficiency of the panel assembly 1.

[0073] As shown in Figure 8 and Figure 9 In some embodiments, the first direction is the left-right direction, each digital display unit 242 includes first to seventh light sources 2420-2426 which are independently arranged, the first to sixth light sources 2420-2425 are located on four sides of a same rectangle, and the seventh light source 2426 is located in the rectangle.

[0074] It can be seen that each digital display unit 242 includes first to seventh light sources 2420-2426 which are independently arranged, the first to sixth light sources 2420-2425 are located on four sides of a same rectangle, and the seventh light source 2426 is located in the rectangle. Then, the digital display unit 242 can form a structure similar to an “8” character. By controlling the on-off states of different light sources, the digital display unit 242 can be switched between different numbers, which improves the richness of the display content of the digital display unit 242.

[0075] For example, the first, fifth, and sixth light sources 2420, 2424, and 2425 of the digital display unit 242 are turned on, and other display light sources of the first and third digital display units 2427 and 2429 are turned off. Thus, the first digital display unit 242 forms a downwardly open character, which is similar to the outline of squinting eyes. In combination with the groove 14 formed on the front side of the panel assembly 1, which is similar to the outline of a face, the face squinting style can be formed on the display panel 10. Of course, more expression styles can be formed by controlling the digital display unit 242.

[0076] As shown in Figure 8 and Figure 9As shown, in some embodiments, the plurality of digital display units 242 includes a first digital display unit 2427, a second digital display unit 2428 and a third digital display unit 2429 arranged in sequence, and the expression display unit 24 further includes a first pattern display unit 244 for displaying a pattern, and the upper side of the first digital display unit 2427 and the third digital display unit 2429 is respectively provided with the first pattern display unit 244, and the lower side of the second digital display unit 2428 is provided with the first pattern display unit 244.

[0077] As can be seen, the plurality of digital display units 242 includes a first digital display unit 2427, a second digital display unit 2428 and a third digital display unit 2429 arranged in sequence, each digital display unit 242 can switch between different numbers, and can be combined into a larger display area, and this combination makes the display content more diverse and complex, meeting different display needs, for example, it can be combined to display time, date, temperature and other information, or used to display complex digital sequences and codes; the upper side of the first digital display unit 2427 and the third digital display unit 2429 is respectively provided with the first pattern display unit 244, and the lower side of the second digital display unit 2428 is provided with the first pattern display unit 244, by setting the pattern display unit 24 at different positions, additional visual levels and stereoscopic effects can be added in the digital display area, making the digital display unit 242 more lively, the first pattern display unit 244 can not only display numbers, but also show various patterns and symbols, expanding the application range of the digital display unit 242, so that the digital display unit 242 can be used in a wider range of scenes and purposes.

[0078] Exemplarily, the first digital display unit 2427 and the third digital display unit 2429 can form an outline similar to an eye on the panel assembly 1, the upper side inside the first digital display unit 2427 and the third digital display unit 2429 is respectively provided with the first pattern display unit 244, the first pattern display unit 244 inside the first digital display unit 2427 and the first pattern display unit 244 inside the third digital display unit 2429 can be used as an expression similar to open eyes when displayed, the first digital display unit 2427 and the first pattern display unit 244 inside the first digital display unit 2427 can switch display, the third digital display unit 2429 and the first pattern display unit 244 inside the third digital display unit 2429 switch display, so as to switch between squinting and opening eyes to realize a dynamic expression similar to blinking; the lower side inside the second digital display unit 2428 is provided with the first pattern display unit 244, so as to form an outline similar to a mouth on the lower side inside the second digital display unit 2428, and the cooperation of the first digital display unit 2427, the third digital display unit 2429 and the first pattern display unit 244 can constitute a smiling face pattern, which increases the visual attraction. Of course, the user can realize more complex expression display through controlling the first digital display unit 2427, the second digital display unit 2428, the third digital display unit 2429 and the first pattern display unit 244. Thus, it is convenient to display more abundant content on the display panel 10, and a more intuitive and interesting interactive experience is provided for the user.

[0079] As shown in FIGS. 1, 2 and 3, in some embodiments, the first direction is a left-right direction, each digital display unit 242 includes independently arranged first to seventh light sources 2420-2426, the first to sixth light sources 2420-2425 are located on four sides of a rectangle, and the seventh light source 2426 is located inside the rectangle. Figure 8 Figure 9 As shown in FIGS. 1, 2 and 3, in some embodiments, the first direction is a left-right direction, each digital display unit 242 includes independently arranged first to seventh light sources 2420-2426, the first to sixth light sources 2420-2425 are located on four sides of a rectangle, and the seventh light source 2426 is located inside the rectangle.

[0080] ​It can be seen that different patterns can be formed on the display panel 10 by controlling the first to seventh light sources 2420-2426 independently arranged in each digital display unit 242. For example, the first, fifth and sixth light sources 2420, 2424 and 2425 of the first and third digital display units 2427 and 2429 are turned on, and the other display light sources of the first and third digital display units 2427 and 2429 are turned off, so that the first and third digital display units 2427 and 2429 form an open downward U-shaped pattern similar to the outline of an eye. The first pattern display unit 244 is arranged on the upper side of the inside of the first and third digital display units 2427 and 2429, and the first pattern display unit 244 includes the eighth to eleventh light sources 2440-2443 arranged independently. The eighth and eleventh light sources 2440 and 2443 are respectively located on the four sides of the rectangular shape. The eighth to eleventh light sources 2440-2443 in the first pattern display unit 244 are turned on, so that the first pattern display unit 244 forms a bright spot or a circular pattern in the groove 14, which is similar to the pupil of an eye. Thus, the first digital display unit 2427 and the first pattern display unit 244 inside it, and the third digital display unit 2429 and the first pattern display unit 244 inside it, cooperate to facilitate the realization of the blinking dynamic expression. The first pattern display unit 244 arranged on the lower side of the inside of the second digital display unit 2428 is turned on, so as to form a bright spot or a circular pattern on the lower side of the inside of the second digital display unit 2428, which is similar to the outline of a mouth. Thus, the cooperation of the first digital display unit 2427, the third digital display unit 2429 and the first pattern display unit 244 can constitute a smiling face pattern, which increases the visual attraction. Of course, the user can also control the on-off state of the eighth to eleventh light sources 2440-2443 in the first pattern display unit 244 inside the first and third digital display units 2427 and 2429, and the on-off state of the first, fifth and sixth light sources 2420, 2424 and 2425 of the first and third digital display units 2427 and 2429, to realize the action similar to blinking.For example, turning on the eighth light source 2440 to the eleventh light source 2443 in the first pattern display unit 244 within the first digital display unit 2427 and the third digital display unit 2429, and turning off the first light source 2420, the fifth light source 2424, and the sixth light source 2425 in the first digital display unit 2427 and the third digital display unit 2429, facilitates the formation of a squinting outline on the display panel 1. Turning off the eighth light source 2440 to the eleventh light source 2443 in the first pattern display unit 2444 within the first digital display unit 2427 and the third digital display unit 2429, and turning on the first light source 2420, the fifth light source 2424, and the sixth light source 2425 in the first digital display unit 2427 and the third digital display unit 2429, facilitates the formation of an open-eyed outline on the display panel 1.

[0081] like Figure 8 and Figure 9 As shown, in some embodiments, there are three or more number display units 242, and the display module 20 also includes a decimal point display unit 2430. The decimal point display unit 2430 is located between two adjacent number display units 242 and is used to display the decimal point. Thus, the numerical information displayed by the multiple number display units 242 and the decimal point display unit 2430 has at least one decimal place.

[0082] As can be seen, by setting a decimal point display unit 2430 between two adjacent digital display units 242, the way numbers are expressed is more in line with people's reading habits, which helps users understand and recognize the displayed numbers more quickly. The combination of multiple digital display units 242 and decimal point display unit 2430 can display the temperature with accuracy to the decimal point. This is especially important for air conditioners that require fine control of indoor temperature. Users can adjust the temperature to the most suitable range according to their actual needs and improve comfort.

[0083] It is understandable that users can select the number of digital display units 242 according to their actual needs, which is convenient for improving the display accuracy of digital display units 242.

[0084] like Figure 8 and Figure 9 As shown, in some embodiments, the display module 20 further includes a second pattern display unit 246 disposed on the circuit board 22. The second pattern display unit 246 is used to display a pattern and is opposite to the second region 13. The expression display unit 24 is in the second direction (e.g., Figure 2 At least one of the two sides of the display panel 10 in the BB' direction is provided with at least one second pattern display unit 246, and both the first direction and the second direction are perpendicular to the thickness direction of the display panel 10.

[0085] It can be seen that the second pattern display unit 246 can display various patterns such as mode icons, function icons, etc., increasing the display content of the panel assembly 1, and the second pattern display unit 246 in combination with the digital display unit 242 makes the entire display panel 10 more lively and interesting, and in the use process, the user can intuitively see different patterns, and different patterns correspond to different working modes, so that the user can more easily understand and operate various functions.

[0086] Among them, the digital display unit 242 is provided with at least one second pattern display unit 246 on at least one side of the two sides in the second direction, so that the layout of the digital display unit 242 and the second pattern display unit 246 in the second direction is more compact, and the space on the panel assembly 1 can be fully utilized.

[0087] It can be understood that the number of second pattern display units 246 can be adjusted according to functional requirements. For example, the air conditioner has multiple working modes, wind speed settings, temperature adjustment ranges, and other additional functions (such as a timing switch, air quality monitoring, etc.), so more second pattern display units 246 are needed to intuitively display these function icons.

[0088] As shown in Figure 7 In some embodiments, the second pattern display unit 246 is multiple and is used to display at least two of networking information, energy-saving information, electric auxiliary heating information, dehumidification information, degerming information, voice information (such as whether a microphone is connected), and fresh air information.

[0089] It can be seen that the multiple second pattern display units 246 can correspond to different functional modules, and the multiple second pattern display units 246 can simultaneously display multiple types of information, so that the panel assembly 1 becomes a comprehensive information center, and the user can quickly obtain the networking state, energy-saving effect, working mode, and other important information of the air conditioner by observing the display panel 10 assembly 1. Through the pattern display mode, the user does not need to read complex text instructions to easily understand the meaning of various information, improving the user's operation convenience and reducing the possibility of operation errors caused by misunderstanding information.

[0090] As shown in Figure 2 and Figure 9As shown, in some embodiments, the panel assembly 1 further comprises a template 30 clamped between the display module 20 and the display panel 10, the template 30 is formed with a plurality of hollow structures 32, the expression display units 24 are arranged corresponding to the plurality of hollow structures 32, so that the template 30 separates the plurality of light sources of the expression display units 24; and / or, the panel assembly 1 further comprises a display box 40, the display box 40 is arranged at the back side of the display panel 10, and the display box 40 defines a mounting cavity 41, the side of the mounting cavity 41 facing the display panel 10 is open, and the display panel 10 closes the open side of the mounting cavity 41, and the display module 20 is arranged in the mounting cavity 41.

[0091] The template 30 is clamped between the display module 20 and the display panel 10, the addition of the template 30 enhances the structural stability of the panel assembly 1, the template 30 acts as a support layer between the display module 20 and the display panel 10, and can effectively disperse and withstand pressure or vibration from the outside, thereby reducing the possibility of damage to the internal display units 24; the template 30 is formed with a plurality of hollow structures 32, the plurality of light sources of the expression display units 24 are separated by the hollow structures 32, which can reduce the mutual influence between adjacent light sources, such as light interference, so that the light emitted by each display unit 24 is clearer, and the light generated by each light source can smoothly pass through the template 30 and be displayed on the display panel 10, and the assembly of the display module 20 and the template 30 is more convenient, and in the assembly process, only the expression display units 24 need to be placed in alignment with the hollow structures 32 on the template 30, without the need for complex adjustment and calibration work.

[0092] It can be understood that the structure of the hollow structure 32 is adapted to the arrangement mode of the light source of the expression display unit 24.

[0093] The display box 40 provides a stable mounting environment for the display module 20, enhances the structural stability of the display module 20, and helps to reduce the possibility of damage to the display module 20 due to external force or vibration, and improves the service life of the display module 20, and the display box 40 and the display panel 10 can provide a relatively closed mounting cavity 41, and the display module 20 arranged in the mounting cavity 41 can reduce the possibility of damage to the display module 20 by external environment such as dust and humidity, maintain the cleanliness and dryness of the internal environment of the display module 20, and thereby improve the use reliability of the display module 20.

[0094] As Figures 10-16As shown, in some embodiments, the panel assembly 1 comprises a stencil 30, which is mounted on the circuit board 22 through a positioning structure 50 and a snap structure 60. The positioning structure 50 comprises a positioning hole 54 and a positioning column 52 that are in a positioning fit. The snap structure 60 comprises a first snap hole 62 and a first elastic buckle 64, which extends into the first snap hole 62 and abuts against the edge portion of the first snap hole 62.

[0095] As can be seen, the positioning hole 54 and the positioning column 52 in the positioning structure 50 are in a fit with each other, so that the stencil 30 can be accurately positioned at a predetermined position on the circuit board 22 during installation, reducing the mispositioning and deviation of the stencil 30 and the circuit board 22 during the installation process, and improving the accuracy and reliability of the installation. The first elastic buckle 64 in the snap structure 60 extends into the first snap hole 62 and abuts against the edge portion of the first snap hole 62, forming a stable snap connection. This connection method is firm and reliable, and can effectively reduce the possibility of the stencil 30 loosening or falling off due to vibration or external force during use. Through the cooperation of the positioning structure 50 and the snap structure 60, the installation process of the stencil 30 and the circuit board 22 becomes simple and fast, without the need for additional fasteners or tools. It only needs to align the positioning hole 54 and the positioning column 52 on the circuit board 22 with the stencil 30, and then use the elasticity of the snap structure 60 to snap the stencil 30 on the circuit board 22, thereby improving the production efficiency.

[0096] It can be understood that the positions of the positioning column 52 and the positioning hole 54 are not specifically limited, for example, the positioning column 52 can be located on the stencil 30, and the positioning hole 54 can be located on the circuit board 22, or the positioning column 52 can be located on the circuit board 22, and the positioning hole 54 can be located on the stencil 30, which does not affect the cooperation of the stencil 30 and the circuit board 22 through the positioning structure 50. The positions of the first elastic buckle 64 and the first snap hole 62 are also not specifically limited, for example, the first elastic buckle 64 can be located on the stencil 30, and the first snap hole 62 can be located on the circuit board 22, or the first elastic buckle 64 can be located on the circuit board 22, and the first snap hole 62 can be located on the stencil 30, which does not affect the cooperation of the stencil 30 and the circuit board 22 through the snap structure 60. The number of the positioning structure 50 and the snap structure 60 is also not specifically limited, and users can select a suitable number according to actual needs and space limitations. This design can flexibly select the specific positions of the positioning structure 50 and the snap structure 60 according to actual conditions to meet different needs and requirements.

[0097] As Figure 12 and Figure 13As shown in the drawings, in some embodiments, the panel assembly 1 comprises a display box 40, the display box 40 is provided with a limiting buckle 42 and a second elastic buckle 43 arranged oppositely, the limiting buckle 42 is protruded on the peripheral wall of the mounting cavity 41, the second elastic buckle 43 extends towards the display panel 10, and the limiting buckle 42 and the second elastic buckle 43 are both adapted to abut against one side of the circuit board 22 facing the display panel 10.

[0098] As can be seen, the limiting buckle 42 is protruded on the peripheral wall of the mounting cavity 41 and can directly abut against one side of the circuit board 22, effectively reducing the possibility of displacement or shaking of the circuit board 22 in the mounting cavity 41, the second elastic buckle 43 extends towards the display panel 10 and is in close contact with one side of the circuit board 22 under the action of elastic force, further enhancing the stability of the circuit board 22, through the double action of the limiting buckle 42 and the second elastic buckle 43, the circuit board 22 is effectively fixed in the mounting cavity 41, thereby improving the structural strength of the assembly of the circuit board 22 and the display box 40, helping to resist external impact and vibration and reducing the possibility of damage to the circuit board 22.

[0099] In addition, the design of the limiting buckle 42 and the second elastic buckle 43 makes the installation of the circuit board 22 simple and fast, in the assembly process, only one end of the circuit board 22 needs to be aligned with the position of the limiting buckle 42, so that the above-mentioned one end of the circuit board 22 is fitted on the side of the limiting buckle 42 away from the display panel 1, then the other end of the circuit board 22 is pressed gently, the second elastic buckle 43 is in contact with and fixed to the circuit board 22, without the need for additional screws or other fasteners 45, reducing the assembly difficulty and cost, and when the circuit board 22 needs to be replaced due to failure, only the circuit board 22 needs to be pulled out from one end of the second elastic buckle 43, without the need to disassemble other components or damage the original fixing structure, reducing the maintenance difficulty and cost, and improving the maintenance efficiency

[0100] As shown in the drawings, Figure 13 and Figure 14 As shown in the drawings, in some embodiments, the display box 40 is further provided with a third elastic buckle 44, the third elastic buckle 44 is arranged on the side of the circuit board 22 away from the display panel 10, and the third elastic buckle 44 is used to apply an elastic force to the circuit board 22 to move towards the display panel 10.

[0101] As can be seen, the third elastic buckle 44 is arranged on the side of the circuit board 22 away from the display panel 10, forming a double fixing mechanism with the limiting buckle 42 and the second elastic buckle 43, this design not only fixes from one side of the circuit board 22, but also applies pressure from the other side, making the position of the circuit board 22 in the mounting cavity 41 more stable, the presence of the third elastic buckle 44 enhances the stability of the circuit board 22 in the mounting cavity 41, enabling the circuit board 22 to better resist external impact and vibration, and helping to protect the circuit board 22 from damage.

[0102] In addition, the design of the third elastic buckle 44 makes the assembly process of the circuit board 22 simpler. During assembly, the circuit board 22 is simply placed into the mounting cavity 41, and the third elastic buckle 44 will apply an elastic force to the circuit board 22, pushing the circuit board 22 toward the display panel 1. The limiting buckle 42 and the second elastic buckle 43 restrict the movement of the circuit board 22 toward the display panel 1, so as to fix the circuit board 22 in the appropriate position.

[0103] like Figures 13-16 As shown, in some embodiments, the panel assembly 1 includes a display box 40, which is inserted into the display panel 10 along a third direction and locked to the display panel 10 by fasteners 45. The third direction is perpendicular to the thickness direction of the display panel 10, and therefore perpendicular to the thickness direction of the second region 13. It can be understood that the third direction may be parallel to the first direction, parallel to the second direction, or have a certain angle with both the first and second directions.

[0104] As can be seen, the display box 40 is inserted into the display panel 10 along the third direction, making the space utilization of the entire panel assembly 1 more compact in the thickness direction, which helps to reduce the overall thickness of the panel assembly 1 and improve the thinness of the panel assembly 1; the display box 40 is locked to the display panel 10 by the fastener 45, which can enhance the stability of the panel assembly 1. The fastener 45 can reduce the possibility of the display box 40 loosening or falling off during use, thereby improving the overall reliability of the device.

[0105] Furthermore, when assembling the display box 40 and the display panel 10, the display box 40 can be first inserted into the display panel 10 along a third direction, and then the display box 40 and the display panel 10 can be fixed by fasteners 45. When it is necessary to disassemble the display box 40 and the display panel 10, the fasteners 45 can be removed first, and then the display box 40 can be pushed in the opposite direction to remove the display box 40 from the display panel 10, making the installation and disassembly of the display box 40 and the display panel 10 more convenient and improving the convenience and efficiency of maintenance and assembly.

[0106] It is understandable that fastener 45 can be threaded fasteners (such as screws) to make the assembly and disassembly of display box 40 and display panel 10 more convenient.

[0107] like Figures 11-16As shown, in some embodiments, the display box 40 is provided with at least one first plug buckle 46 on one side in the third direction, the back side of the display panel 10 is provided with a first buckle position 15, the first plug buckle 46 is inserted and matched with the first buckle position 15, through the insertion and matching of the first plug buckle 46 and the first buckle position 15, the display box 40 and the display panel 10 can form a stable mechanical cooperation, effectively reducing the possibility of movement or falling of the display box 40 relative to the display panel 10 during use, and the design of the first plug buckle 46 and the first buckle position 15 makes the assembly process of the display box 40 and the display panel 10 more convenient and fast, the operator only needs to align the first plug buckle 46 with the first buckle position 15 and insert it, and the cooperation of the display box 40 and the display panel 10 can be completed, without the need for additional fixing parts or tools, thereby reducing the assembly cost and improving the assembly efficiency; and / or, the display box 40 is provided with at least one second plug buckle 47 on at least one of the two sides in the fourth direction, the back side of the display panel 10 is provided with a second buckle position, the second plug buckle 47 is inserted and matched with the second buckle position 16, the fourth direction is perpendicular to the thickness direction of the display panel 10, the fourth direction is perpendicular to the third direction, and then the fourth direction is also perpendicular to the thickness direction of the second area 13, through the insertion and matching of the second plug buckle 47 and the second buckle position 16, the display box 40 and the display panel 10 can form a stable mechanical cooperation, effectively reducing the possibility of movement or falling of the display box 40 relative to the display panel 10 during use, and the design of the second plug buckle 47 and the second buckle position 16 makes the assembly process of the display box 40 and the display panel 10 more convenient and fast, the operator only needs to align the second plug buckle 47 with the second buckle position 16 and insert it, and the cooperation of the display box 40 and the display panel 10 can be completed, without the need for additional fixing parts or tools, thereby reducing the assembly cost and improving the assembly efficiency. It can be understood that the display box 40 can be provided with the second plug buckle 47 on one side in the fourth direction, or the display box 40 can be provided with the second plug buckle 47 on both sides in the fourth direction, so that the connection between the display box 40 and the display panel 10 is more stable.

[0108] It can be understood that the fourth direction can be parallel to the first direction, then the third direction is parallel to the second direction, or the third direction is parallel to the second direction, then the third direction is parallel to the first direction, or the third direction has a certain angle with the first direction and the second direction, and the fourth direction also has a certain angle with the first direction and the second direction. The third direction and the fourth direction are always perpendicular to and parallel to the plane where the second area 13 is located, which is convenient for the assembly of the display box 40 and the display panel 10.

[0109] As Figure 16As shown, in some embodiments, the back side of the display panel 10 is provided with a first buckle 15 and a second buckle, the first buckle 15 is multiple and the multiple first buckles 15 are arranged in the fourth direction, each first buckle 15 defines a first slot 150, the open sides of two of the multiple first slots 150 are arranged opposite or back to each other, and the second buckle 16 defines a second slot 160, the side of the second slot 160 opposite to the first buckle 15 is open.

[0110] It can be seen that the multiple first buckles 15 form multiple point connections between the display box 40 and the display panel 10, the multiple first buckles 46 can be arranged in the third direction along the display box 40, the side of the first buckles 46 is inserted and matched with the multiple first buckles 15, the multiple first buckles 46 are located in the multiple first slots 150, and the stability and firmness of the connection are enhanced, the second buckle 16 provides additional insertion points for the display box 40 and the display panel 10, and since the open side of the second slot 160 is back to the first buckle 15, the first slot 150 and the second slot 160 are spaced apart, the second buckle 16 can provide additional support and fixation for the display panel 10 without affecting the matching of the first buckle 15, and the stability of the connection is further enhanced.

[0111] In addition, the open sides of two of the multiple first slots 150 are arranged opposite or back to each other, so that the setting form of the first buckle 15 is more flexible, and can adapt to diversified installation requirements, and the cooperation of the multiple first buckles 15 can limit the movement of the display box 40 in the fourth direction relative to the display panel 10; and the cooperation of the first buckle 15 and the second buckle 16 can timely remind whether the display box 40 is inserted in place during the insertion process.

[0112] As shown, Figure 9 In some embodiments, the template 30 further includes a mounting hole, and the circuit line can be electrically connected with the circuit board 22 through the mounting hole, so that the panel assembly 1 is more compact in structure, and the mounting hole provides a channel for assembly and disassembly of the circuit line, so that when the circuit line fails or needs to be upgraded, the mounting hole can be easily disassembled and replaced, and the maintenance cost is reduced.

[0113] According to the air conditioner of the second aspect of the utility model, the panel assembly 1 is adopted, the diversity of display content of the air conditioner is facilitated, and the brand characteristics are strengthened.

[0114] According to the air conditioner of the utility model, the panel assembly 1 is adopted, the diversity of display content of the air conditioner is facilitated, and the brand characteristics are strengthened.

[0115] It can be understood that the type of the air conditioner of the embodiments of the present application is not limited, and can be a vehicle-mounted air conditioner, and can also be an all-in-one air conditioner or a split air conditioner. The all-in-one air conditioner can include a window air conditioner or a mobile air conditioner, etc. The split air conditioner can include an air conditioner hanging machine or an air conditioner cabinet machine, etc.

[0116] As shown in FIGS. 1 and 2, in some embodiments, the first area 12 is also configured as a light-transmitting display area, and the display module 20 further includes a lighted display unit 240 arranged on the circuit board 22. The lighted display unit 240 is opposite to the first area 12, and the lighted display unit 240 is configured to emit light of different colors for displaying different working modes of the air conditioner. Figure 1 Figures 8-9 As shown in FIGS. 1 and 2, in some embodiments, the first area 12 is also configured as a light-transmitting display area, and the display module 20 further includes a lighted display unit 240 arranged on the circuit board 22. The lighted display unit 240 is opposite to the first area 12, and the lighted display unit 240 is configured to emit light of different colors for displaying different working modes of the air conditioner.

[0117] It can be seen that, by emitting light of different colors through the lighted display unit 240, the user can intuitively identify the current working mode of the air conditioner. This visual feedback is more intuitive than text or symbols, so that the user can quickly understand the state of the air conditioner, and the user can quickly judge and adjust the working mode of the air conditioner by observing the color change of the lighted display unit 240.

[0118] For example, the lighted display unit 240 can emit light of three colors of white, blue and orange yellow. The white color represents that the air conditioner is in a dehumidification / air supply mode, the blue color represents that the air conditioner is in a cooling mode, and the orange yellow represents that the air conditioner is in a heating mode. In some examples, the lighted display unit 240 can emit light of four colors of red, green, blue and yellow. When the lighted display unit 240 emits red light, it represents that the air conditioner is in a heating mode. When the lighted display unit 240 emits blue light, it represents that the air conditioner is in a cooling mode. When the lighted display unit 240 emits green light, it represents that the air conditioner is in a cooling mode dehumidification or intelligent mode. When the lighted display unit 240 emits yellow light, it represents that the air conditioner is in failure and needs to be repaired.
