Description

Technical Field

[0001] The present invention belongs to the field of household appliances, and more specifically, relates to a display device for a household appliance and a household appliance. Background Art

[0002] Currently, common household appliances usually have a control screen for receiving control instructions and a display screen for displaying images, such as washing machines and range hoods. Taking a washing machine as an example, the display screen and the control screen of a conventional washing machine are currently presented on the same plane. In actual products, in order to facilitate users to issue control instructions on the control screen, the control screen is usually set horizontally. When a user wants to observe the displayed content through the display screen, the user needs to approach the display screen to see it. That is to say, the user cannot observe the displayed content from a distance, and the viewing range is small, which affects the user experience.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a display device for a household appliance and a household appliance in which the displayed content in a display area is projected onto the display surface through a light-transmitting area of an identification surface, and when the user is at a certain distance from the display area, the user can also see the displayed content in the display area through an imaging structure.

[0005] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] On the one hand, a display device for a household appliance is provided.

[0007] A control panel having a connected operation plane and a display plane; an operation area is provided on the operation plane, and a display area is provided on the display plane;

[0008] An imaging structure is provided above the display area, having an identification surface disposed opposite to the display plane and a display surface at an angle to the operation plane; the identification surface has a light-transmitting area and a shielding area, the projection of the display area onto the identification surface is located within the light-transmitting area, and the displayed content in the display area is projected onto the display surface through the light-transmitting area of the identification surface for display.

[0009] The display device provided by the present invention includes a control panel and an imaging structure. The imaging structure is disposed above the display area on the control panel, and the display content in the display area is refracted to the display surface through the light-transmitting area of the recognition surface for display. During installation, in order to facilitate user operation, the operation plane is usually set horizontally. In this solution, since there is a certain angle between the display surface and the operation plane, the user can observe the display content on the display screen through the display surface of the imaging structure, thereby increasing the viewing range of the user for the display area and improving the user experience.

[0010] Further, the imaging structure is a right-angled triangular prism made of a transparent material;

[0011] One right-angled surface of the right-angled triangular prism serves as the recognition surface and is disposed above the display area. The content in the display area passes through the light-transmitting area of the recognition surface and is refracted to the inclined surface, and then refracted by the inclined surface to another right-angled surface serving as the display surface for display;

[0012] The inclined surface of the right-angled triangular prism has an opaque shielding structure.

[0013] Further, the two end faces on both sides of the right-angled triangular prism have opaque shielding structures.

[0014] Further, a film with one-way light transmission is covered in the area where the projection of the display area on the recognition surface is located.

[0015] Further, the display device further includes a support member with a certain extension length, and the support member supports the right-angled triangular prism by abutting against the reflection surface thereof.

[0016] Further, the support member is a hollow structure, and it includes:

[0017] A first support plate, disposed parallel to the recognition surface, and one end abuts against the end of the inclined surface away from the recognition surface;

[0018] A second support plate, connected to the other end of the first support plate, and a plane extending towards the recognition surface;

[0019] A third support plate, connecting the first support plate and the second support plate; the third support plate is disposed in abutment with the reflection surface of the right-angled triangular prism.

[0020] Further, the third support plate has square holes arranged at intervals.

[0021] Further, the first support plate extends from the connection with the second support plate towards the direction away from the display surface, and the extended end is connected with a fourth support plate. The other end of the fourth support plate extends obliquely downward, and the extended end abuts against the fixing frame for fixing the control panel.

[0022] Further, the control panel includes a first panel having a display area and a second panel disposed perpendicular to the first panel;

[0023] A clamping protrusion is provided on the outer side of the second support plate, and the clamping protrusion is clamped at the upper end of the second panel.

[0024] On the other hand, a household appliance is also provided. The household appliance includes the display device of the above-mentioned household appliance.

[0025] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0026] 1. The display device provided by the present invention includes a control panel and an imaging structure. The imaging structure is disposed above the display area on the control panel, and the display content in the display area is refracted to the display surface through the light-transmitting area of the recognition surface for display. During installation, in order to facilitate user operation, the operation plane is usually set horizontally. In this solution, since there is a certain angle between the display surface and the operation plane, the user can observe the display content on the display screen through the display surface of the imaging structure, thereby increasing the viewing range of the user for the display area and improving the user experience.

[0027] 2. Since the imaging structure provided by the present invention is a prism made of a transparent material, the display screen that emits light at the bottom of the prism is refracted to the display surface at the front end of the prism through refraction, achieving a spatial conversion. And the permeability of the prism is very high, which can make the display effect three-dimensional and increase the three-dimensional sense.

[0028] 3. The inclined surface and the two end faces of the prism in the present invention have opaque shielding structures, so that the user can only see the content refracted to the display surface through the light-transmitting area, and cannot see the installation structures at the bottom and side of the prism, thereby improving the user's sensory experience.

[0029] 4. Since the display device provided by the present invention further includes a support member for supporting the prism, the prism is fixed on the control panel.

[0030] The following further describes in detail the specific embodiments of the present invention with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] As Figures 1 to 11 shown, the present invention provides a display device for a household appliance and a household appliance.

[0055] Among them, the display device includes:

[0056] A control panel 1, having a connected operation plane and a display plane; an operation area is provided on the operation plane, and a display area is provided on the display plane;

[0057] An imaging structure is disposed above the display area and has an identification surface disposed opposite to the display plane and a display surface 201 disposed at an angle to the operation plane; the identification surface has a light-transmitting area and an occlusion area, and the projection of the display area onto the identification surface is located within the light-transmitting area, and the display content in the display area is projected onto the display surface 201 through the light-transmitting area of the identification surface for display.

[0058] For the display device provided by the present invention, the display content of the display area is refracted to the display surface through the light-transmitting area of the identification surface for display. Since there is a certain angle between the display surface and the operation plane, the user can observe the display content on the display screen through the display surface of the imaging structure, thereby increasing the viewing range of the user for the display area and improving the user experience.

[0059] On the other hand, a household appliance is also provided, and the household appliance includes the display device of the above-mentioned household appliance.

[0060] Embodiment 1

[0061] As Figure 1 and Figure 2 shown, this embodiment provides a display device for a household appliance.

[0062] The display device includes:

[0063] A control panel 1 having a connected operation plane and a display plane; an operation area is provided on the operation plane, and a display area is provided on the display plane;

[0064] An imaging structure is disposed above the display area and has an identification surface disposed opposite to the display plane and a display surface 201 disposed at an angle to the operation plane; the identification surface has a light-transmitting area and an occlusion area, and the projection of the display area onto the identification surface is located within the light-transmitting area, and the display content in the display area is projected onto the display surface 201 through the light-transmitting area of the identification surface for display.

[0065] The household appliance in this embodiment is an appliance such as a washing machine or a range hood having an operation area and a display area. In this embodiment, a washing machine is taken as an example for illustration.

[0066] In this solution, the display device of the washing machine includes a control panel 1 and an imaging structure. The control panel 1 has a connected operation area and a display area. When in use, the user can send a control instruction to the washing machine by controlling the operation area, and the display area can display an image of relevant information during the washing process. For example, information such as the currently executing washing program, the washing temperature situation, and the remaining washing time.

[0067] Among them, the imaging structure is disposed at a position above the display area. The imaging structure has an identification surface disposed opposite to the display plane and a display surface 201 disposed at an angle to the operation plane. Among them, the identification surface has a light-transmitting area and an occlusion area, and the projection of the display area onto the identification surface is located within the light-transmitting area. That is to say, the display content of the display area can be displayed through the light-transmitting area and cannot be displayed through the occlusion area. When in use, the display content in the display area is projected onto the display surface 201 through the light-transmitting area of the identification surface, so that the user can only see the content refracted to the display surface through the light-transmitting area to know the washing-related information and cannot see the installation structure below the occlusion area, thereby improving the user's sensory experience.

[0068] For the display device provided in this embodiment, since there is a certain angle between the display surface and the operation plane, the user can observe the display content on the display screen through the display surface of the imaging structure, thereby increasing the viewing range of the user for the display area and improving the user experience.

[0069] In a specific solution of this embodiment, the operation plane where the operation area on the control panel is located and the display plane where the display area is located are different planes.

[0070] Specifically, the control panel 1 includes a mounting plate, and a control screen 104 and a display screen 103 disposed on the mounting plate;

[0071] The control screen 104 is mounted in the operation area, and the display screen 103 is mounted in the display area;

[0072] The imaging structure is mounted on the upper surface of the mounting plate, at least covering the display screen 103.

[0073] More specifically, the mounting plate includes a first mounting plate 101 for mounting the control screen 104 and a second mounting plate 102 for mounting the display screen 103;

[0074] There is a certain angle between the first mounting plate 101 and the second mounting plate 102.

[0075] In the solution of this embodiment, the control panel 1 includes a mounting plate, and a display screen 103 and a control screen 104 disposed on the mounting plate. The control screen 104 has text corresponding to control instructions, and the display screen 103 has pattern information. Among them, the mounting plate includes two parts, namely a first mounting plate 101 and a second mounting plate 102. The first mounting plate 101 has an operation area, and the control screen 104 is mounted in the operation area. The second mounting plate 102 has a display area, and the display screen 103 is mounted in the display area. The imaging structure is mounted on the upper surface of the second mounting plate 102 above the display screen 103.

[0076] In this solution, the first mounting plate 101 and the second mounting plate 102 are not in the same plane. That is to say, the first mounting plate 101 and the second mounting plate 102 are connected to each other and there is a certain angle between them, so that the display screen 103 and the control screen 104 are not in the same plane and there is an included angle between them.

[0077] In a specific solution of this embodiment, the mounting plate is an integrally formed structure, and the angle between the first mounting plate 101 and the second mounting plate 102 is fixed and cannot be adjusted.

[0078] In another specific solution of this embodiment, the mounting plate is not an integrally formed structure. The first mounting plate 101 and the second mounting plate 102 are connected by a rotating shaft, and the angle between them can be adjusted at any time according to the user's needs.

[0079] In the solution provided in this embodiment, since the control screen 104 and the display screen 103 are not arranged in the same plane, the areas of the control screen 104 and the display screen 103 are increased, so that the fonts on the control screen 104 and the patterns on the display screen 103 can be freely designed, improving the user experience.

[0080] In another specific solution of this embodiment, the operation plane where the operation area on the control panel is located is the same plane as the display plane where the display area is located. In this solution, the display screen and the control screen are separately arranged, but both of them are in the same plane. For example, both the display screen and the control screen are horizontally arranged, and the display device is installed above the display screen, and there is a certain angle between the display surface on the display device and the control screen, and this angle can be ninety degrees. That is to say, the display surface is vertically arranged with the control screen, so that the user does not need to walk to the position where the display screen is located to observe the content of the display screen, and can see the display content of the display screen through the display surface of the display device in the distance. The visual range of the user observing the display area is increased, improving the user experience.

[0081] The solution of this embodiment further includes: the imaging structure is a prism 2 made of a transparent material, and the display surface 201 is a side surface of the prism 2 at a certain angle with the operation plane.

[0082] The prism 2 includes a right-angled triangular prism 2. One right-angled surface of the right-angled triangular prism 2 is used as the identification surface 202 and is arranged above the display area. The content of the display area is refracted through the identification surface 202 to the inclined surface serving as the reflection surface 203, and then refracted by the reflection surface 203 to the other right-angled surface serving as the display surface 201 for display.

[0083] Specifically, the imaging structure further includes a reflecting surface 203 disposed above the display area. The display content irradiates from the display area to the reflecting surface 203 and is reflected by the reflecting surface 203 to the display surface 201 for display.

[0084] The imaging structure further includes an identification surface 202 disposed parallel above the display screen 103. The display content in the display area is refracted through the identification surface 202 to the reflecting surface 203.

[0085] In the solution of this embodiment, the imaging structure is a prism 2 made of a transparent material. The prism 2 is made of all materials that can display transparently, such as glass, crystal, or acrylic.

[0086] In a specific solution of this embodiment, the imaging structure is a right-angled triangular prism 2 structure.

[0087] In this solution, since the right-angled triangular prism 2 has two right-angled faces and one inclined face. Among them, one right-angled face serves as the identification surface 202, the other right-angled face serves as the display surface 201, and the inclined face serves as the reflecting surface 203.

[0088] During installation, one right-angled face of the right-angled triangular prism 2 is installed on the upper surface of the second mounting plate 102 and is disposed parallel above the display screen 103. This right-angled face serves as the identification surface 202. The other right-angled face is disposed close to the first mounting plate 101 and serves as the display surface 201. The inclined face disposed above the display area is the reflecting surface 203. Since the right-angled triangular prism 2 is made of a transparent material, the display content on the display screen 103 can be refracted through the identification surface 202 to the reflecting surface 203 under the irradiation of light, and then reflected by the reflecting surface 203 to the display surface 201. The user can then see the display content of the display screen 103 on the display surface 201.

[0089] In a further solution of this embodiment, since the imaging structure is a right-angled triangular prism 2, its cross-section is a transparent body in the shape of a right-angled triangle. In order to better display the image of the display screen 103 on the display surface 201, the two right-angled sides of the right-angled triangle in the cross-section of the prism 2 have the same length.

[0090] As Figure 7 and Figure 8 shown, the solution of this embodiment further includes: The display device further includes a support member with a certain extension length. The support member supports the right-angled triangular prism by abutting against its reflecting surface.

[0091] The support member is a hollow structure and includes:

[0092] A first support plate, disposed parallel to the identification surface, and one end abuts against the end of the inclined face away from the identification surface;

[0093] The second support plate, which is connected to the other end of the first support plate and is a plane extending towards the recognition surface;

[0094] The third support plate, which connects the first support plate and the second support plate; the third support plate is arranged in abutment with the reflecting surface of the right-angled triangular prism.

[0095] The third support plate is provided with square holes arranged at intervals.

[0096] The first support plate extends from the connection with the second support plate in a direction away from the display surface, and a fourth support plate is connected to the extending end. The other end of the fourth support plate extends obliquely downward, and the extending end abuts on the fixing bracket of the fixed control panel.

[0097] The control panel includes a first panel having a display area and a second panel arranged perpendicular to the first panel;

[0098] A clamping protrusion is arranged on the outer side of the second support plate, and the clamping protrusion is clamped on the upper end of the second panel.

[0099] In this solution, since there is an included angle between the display screen 103 and the control screen 104, and the angle between the two is greater than 180 degrees. Generally, in order to facilitate the user to issue control commands on the control screen 104, the control screen 104 is usually arranged in a horizontal direction, while the display screen 103 is arranged obliquely. In order to better install the prism 2 above the display screen 103, a support member 4 is arranged behind the right-angled triangular prism.

[0100] In a specific solution of this embodiment, the support member has a certain extended length like the right-angled triangular prism. It includes a first support plate 401 and a second support plate 402 that are connected to each other and have a certain included angle. The first support plate is arranged parallel to the recognition surface 202, one end abuts against the end of the reflecting surface 203 away from the recognition surface, and the other end is connected to the second support plate 402. The second support plate 402 extends towards the recognition surface 202, and the extending end of the second support plate 402 abuts against the end of the reflecting surface 203 close to the recognition surface 202.

[0101] In the preferred solution of this embodiment, the included angle between the first support plate 401 and the second support plate 402 is 90 degrees.

[0102] In a further solution of this embodiment, the support member further includes a third support plate 403 that connects the first support plate 401 and the second support plate 402. In order to make the support of the first support plate 401 and the second support plate 402 more stable, the third support plate 403 is arranged obliquely so that the three support plates form a stable triangular prism structure. In this solution, the third support plate 403 is arranged in abutment with the reflecting surface 203 of the prism.

[0103] In a further aspect of this embodiment, the second mounting plate includes a first panel and a second panel that is perpendicular to the first panel. The second panel is disposed at one end away from the first mounting plate. Among them, the display screen 103 and the prism 2 are mounted on the first panel. In a specific aspect of this embodiment, a clamping protrusion 405 is provided on the outer side of the second support plate, and the clamping protrusion 405 is clamped at the upper end of the second panel.

[0104] In a still further aspect of this embodiment, the support member further includes a fourth support plate 404.

[0105] In a specific aspect of this embodiment, the first support plate extends from the connection with the second support plate in a direction away from the display surface, and a fourth support plate is connected to the extending end. The other end of the fourth support plate extends obliquely downward, and the extending end abuts against the fixing bracket of the fixed control panel. That is to say, the second support plate 402 is disposed between the first support plate 401 and the fourth support plate 404.

[0106] In this aspect, the display device further includes a fixing bracket 5. The fixing bracket includes a first fixing plate 501 having a certain thickness. The first fixing plate 501 is supported on the cover of the household appliance, and the other end extends obliquely in the direction of the first support plate of the support member. At its extending end, a second fixing plate 502 that is perpendicular to the first fixing plate 501 and extends in the direction of the second support plate on the support member is provided. At the extending end of the second fixing plate 502, a third fixing plate 503 that is perpendicular to the second fixing plate and extends in the direction of the first support plate on the support member is provided. At the extending end of the third fixing plate 503, a fourth fixing plate 504 that is perpendicular to the third fixing plate and extends in the direction of the second support plate on the support member is provided. At the extending end of the fourth fixing plate 504, a fifth fixing plate 505 that is perpendicular to the fourth fixing plate and extends in a direction away from the first support plate on the support member is provided. At the extending end of the fifth fixing plate 505, a sixth fixing plate 506 that is parallel to the second mounting plate is provided. The outer side of the second mounting plate 402 abuts against the sixth fixing plate 506.

[0107] The other end of the fourth support plate 404 is clamped on the second fixing plate 502, and the inner surface of the fourth support plate 404 abuts against the outer surface of the third fixing plate 503. That is to say, the first fixing plate 501 is parallel to the third support plate 403.

[0108] It should be noted that in this aspect, the angle between the first support plate and the fourth support plate is greater than 90 degrees and less than 180 degrees.

[0109] In a specific solution of this embodiment, the support member includes a plurality of support members arranged at intervals. The third support plates 403 of the multiple support members are in abutting support with the reflecting surface 203 of the right-angled triangular prism. In order to make the fixation between the support member 4 and the right-angled triangular prism 2 more firm, glue is applied between the third support plate 403 of the support member and the reflecting surface 203 of the right-angled triangular prism. In addition, in this solution, the widths of the support plates in each support member are the same. End faces are provided at the two outer ends of the two support members at the two ends of the support member.

[0110] It should be noted that in the above solution, the support member is a hollow structure composed of support plates, and the first support plate, the second support plate, the third support plate, and the fourth support plate are all strip-shaped plate structures.

[0111] Such as Figure 7 shown, in a preferred solution of this embodiment, the third support plate has square holes arranged at intervals.

[0112] In a further solution, the intervals between the square holes can be the same or different. The specific interval method is not limited in this solution.

[0113] In other specific solutions of this embodiment, the support member can also be a solid structure.

[0114] In another solution of this embodiment, the imaging structure is a cuboid structure formed by the inclined surfaces of two identical right-angled triangular prisms 2 abutting against each other relatively.

[0115] In this solution, the imaging structure is no longer a transparent triangular prism 2, but a cuboid structure formed by two transparent right-angled triangular prisms 2. Specifically, the imaging structure is a cuboid structure formed by the inclined surfaces of two identical right-angled triangular prisms 2 abutting against each other relatively, and an opaque film is covered on the reflecting surface 203 of the right-angled triangular prism 2 where the display surface 201 is located.

[0116] Since the imaging structure is a prism 2, the pattern on the display screen 103 has a three-dimensional special effect after being reflected by the prism 2, which can convert the original planar image into a three-dimensional pattern, making it more vivid and vivid.

[0117] In another specific solution of this embodiment, the imaging structure is a transparent cuboid prism 2, and the diagonal plane of the cuboid prism 2 is covered with a film.

[0118] The solution of this embodiment further includes: the angle between the operation plane and the display plane is greater than one hundred and eighty degrees.

[0119] In the above solution, the angle between the first mounting plate 101 and the second mounting plate 102 is greater than 180 degrees. That is to say, the display screen 103 and the control screen 104 are not in the same plane, and the included angle between them is greater than 180 degrees. Also, since the imaging structure is arranged above the display screen 103, the included angle between the display surface 201 and the recognition surface 202 is 90 degrees, that is, the angle between the display surface 201 and the display screen 103 is also 90 degrees. In this way, the angle between the display surface 201 and the control screen 104 is greater than 90 degrees, providing a wider viewing field for the user.

[0120] The display device provided in this embodiment breaks the conventional assembly solution by arranging the display screen 103 and the control screen 104 on different planes respectively, greatly improving the space of the operation area and the display area, fundamentally solving the problems of insufficient interface space and compact layout, and improving the user experience.

[0121] As Figures 3 to 6 shown, the solution of this embodiment further includes: at least the mounting plate of the display area has a certain thickness and is provided with a groove-like structure 109 with an upward opening, and the display screen 103 is mounted in the groove-like structure 109.

[0122] Further, at least two convex blocks 110 are symmetrically arranged in the lower region of the side wall of the groove-like structure 109. The upper ends of the convex blocks 110 are lower than the upper surface of the mounting plate, and the display screen 103 is mounted above the convex blocks 110.

[0123] The protruding structure is formed by the upper part of the side wall of the groove-like structure protruding above the upper surface of the mounting plate.

[0124] The second mounting plate 102 is a rectangular structure with a certain extension length and also has a certain thickness. There is a groove-like structure 109 with an upward opening on the second mounting plate 102. The groove-like structure 109 includes a first groove-like structure 1091 and a second groove-like structure 1092 arranged in the middle region of the first groove-like structure 1091.

[0125] As Figure 11 shown, to prevent water vapor from entering the recognition surface of the imaging structure, a protruding portion is provided on the recognition surface of the right-angled triangular prism, and the protruding portion is embedded in the first groove-like structure.

[0126] In the specific solution of this embodiment, the shape of the second groove-like structure 1092 is the same as that of the display screen 103, both being rectangular structures. The size of the second groove-like structure 1092 is the same as or slightly larger than the size of the display screen 103.

[0127] The second groove-shaped structure 1092 has four side walls and a bottom wall, namely a symmetric front side wall and a rear side wall, a left side wall and a right side wall, and a bottom wall disposed below. Protrusions 110 are provided on at least one set of symmetric side walls. For example, two protrusions 110 are symmetrically provided on the front side wall and the rear side wall, or two protrusions 110 are symmetrically provided on the left side wall and the right side wall.

[0128] In the specific solution of this embodiment, in order to fix the display screen 103 more firmly, a plurality of protrusions 110 are provided on the four side walls of the second groove-shaped structure 1092. More specifically, the protrusions 110 are all provided in the lower regions of the four side walls, and the upper ends of the protrusions 110 are lower than the upper surface of the mounting plate. That is to say, there is a certain distance between the upper ends of the protrusions 110 and the upper end of the second groove-shaped structure 1092. During installation, the display screen 103 is placed into the second groove-shaped structure 1092, and the lower surface of the display screen 103 abuts against the upper end surfaces of the protrusions 110. That is to say, in this solution, the display screen 103 is fixed in the second groove-shaped structure 1092 by the protrusions 110 provided on the side walls of the second groove-shaped structure.

[0129] In a more specific solution of this embodiment, the display screen includes a PCB display board, a sponge, and a color film. The PCB display board is disposed at the lowermost position and abuts and fixes against the protrusions, and the sponge and the color film are sequentially installed above the PCB display board.

[0130] In another solution of this embodiment, no protrusions 110 are provided on the side walls of the second groove-shaped structure 1092, and the display screen 103 is directly placed in the second groove-shaped structure 1092 and abuts against the bottom wall of the second groove-shaped structure.

[0131] In another solution of this embodiment, the second mounting plate 102 is also a plate-shaped structure with a certain thickness, but no grooves are provided thereon. Instead, through holes penetrating through it are provided thereon, and protrusions 110 are provided on the side walls of the through holes. During use, the display screen 103 is placed into the through holes for fixation.

[0132] In the preferred solution of this embodiment, since the display screen 103 has a certain thickness and the imaging structure is disposed on the inner surface of the second mounting plate 102. To prevent the gravity of the imaging structure from directly acting on the display screen 103 and breaking the display screen 103, when the display screen 103 is installed in place, the upper surface of the display screen 103 is flush with or lower than the upper surface of the second mounting plate 102.

[0133] In the solution of this embodiment, since the imaging structure is a prism 2 made of transparent glass with a smooth outer surface, it is not easy to be fixed on the upper surface of the second mounting plate 102. Therefore, limiting structures are provided on both the prism 2 and the second mounting plate 102 to fix the prism 2 more firmly on the second mounting plate 102.

[0134] As Figure 4 shown, specifically, the limiting structure includes a convex structure provided on the upper surface of the second mounting plate 102 and a groove structure provided at the bottom of the prism 2. After the prism 2 is placed on the second mounting plate 102, the convex structure on the second mounting plate 102 is inserted into the groove structure at the bottom of the prism 2 to limit and fix the two.

[0135] More specifically, the convex structure includes a first convex structure 105 and a second convex structure 106. Correspondingly, the groove structure also includes a first groove structure 107 provided corresponding to the first convex structure 105 and a second groove structure 108 provided corresponding to the second convex structure 106.

[0136] Among them, the first convex structure 105 is formed by the upper part of the side wall of the second groove-like structure 1092 protruding from the upper surface of the mounting plate. Since the through hole has four side walls, the first convex structure 105 is a square frame surrounded by four convex lines connected end to end. The second convex structure 106 is a convex line perpendicular to the extending direction of the second mounting plate 102.

[0137] In a specific solution of this embodiment, one first convex structure 105 is provided, and two second convex structures 106 are symmetrically provided. Since the middle area of the second mounting plate 102 is prone to deformation, resulting in misalignment with the prism 2, the first convex structure 105 is provided at the middle position of the second mounting plate 102, and a second convex structure 106 is provided on each side of the first convex structure 105.

[0138] As Figure 10 shown, correspondingly, the first groove structure 107 is provided in the middle area at the bottom of the prism 2, and it is a square frame structure surrounded by four groove lines connected end to end. The second groove structure 108 is provided at the left end and the right end of the bottom of the prism 2, and is a groove line perpendicular to the length direction of the prism 2.

[0139] In other specific solutions of this embodiment, the extending direction of the second limiting rib 111 can be other directions, and the number of the second limiting ribs 111 provided can also be other numbers, which are not specifically limited herein.

[0140] Of course, in order to connect the prism 2 and the second mounting plate 102 more firmly, the depth of the groove structure and the protruding height of the protruding structure can be increased. The area of the groove structure on the second mounting plate 102 and the area of the protruding structure at the bottom of the prism 2 can also be increased.

[0141] The solution of this embodiment further includes: a unidirectional light-transmitting film is covered at the area where the projection of the display area on the recognition surface is located.

[0142] In the specific structure of this embodiment, since the display screen is installed in the second groove-shaped structure on the second mounting plate, and the recognition surface of the prism is installed on the second mounting plate. Also, since the prism is made of a transparent material, the user can not only see the display screen through the prism, but also see the area outside the display screen through the prism, which affects the user's sensory experience.

[0143] To improve the user's sensory experience, a unidirectional light-transmitting film is covered at the area where the projection of the display area on the recognition surface is located. For example, a dark film is covered in the light-transmitting area. In this way, when the lights on the PCB display board are not on, the user cannot see the display content of the display screen through the prism. When the lights on the PCB display board are lit, the display content on the display screen can be reflected by the film to the display surface for display.

[0144] Paint, printed promotional slogans or patterns can be applied to the shielding area of the prism recognition surface, or colored stickers can be pasted.

[0145] When no protruding structure is provided in the middle of the prism, in order to distinguish the light-transmitting area and the shielding area, the light-transmitting area and the shielding area have different colors. For example, the shielding area is sprayed with black paint, and a light yellow film is pasted on the light-transmitting area.

[0146] To further improve the user's sensory experience and make the support member behind the prism and other structures on the side invisible, opaque shielding structures are installed on the inclined surface of the prism and the two end faces on both sides of the prism. For example, the inclined surface of the prism and the two end faces on both sides of the prism are printed or sprayed, or an opaque film is pasted.

[0147] The solution of this embodiment further includes: a limiting rib 111 that is in stop cooperation with the imaging structure is provided on one side of the display area of the control board 1 away from the operation area.

[0148] To facilitate the user to input control instructions on the control panel 104, the control panel 104 is generally arranged in the horizontal direction. Also, since the angle between the first mounting plate 101 and the second mounting plate 102 is greater than 180 degrees, that is to say, the second mounting plate 102 is inclined downward relative to the horizontal direction, and the prism 2 on the second mounting plate 102 is also likely to slide down. To prevent the prism 2 from slipping off the second mounting plate 102, a limiting rib 111 that is in stop cooperation with the imaging structure is provided on the side of the second mounting plate 102 away from the first mounting plate 101.

[0149] In this solution, the limiting rib 111 is also a triangular prism structure, and its cross-section is a right triangle. The limiting rib 111 and the second mounting plate 102 are not integrally formed structures. A clamping portion is provided at the bottom of the limiting rib 111, and a clamping groove is provided on the second mounting plate 102. After the convex structure on the second mounting plate 102 is in limit cooperation with the concave structure on the prism 2, the clamping portion on the limiting rib 111 is aligned with the clamping groove on the second mounting plate 102 and inserted to fixedly install the limiting rib 111 on the second mounting plate 102. In this solution, the imaging structure is a cube structure formed by splicing two transparent right-angled triangular prisms 2. When the limiting rib 111 is installed in place, the limiting rib 111 fixes the imaging structure by abutting against the right-angled surface of one of the prisms 2.

[0150] Of course, in other solutions of this embodiment, the limiting rib 111 and the second mounting plate 102 can also be fixedly connected by other means. Or they can be integrally formed structures.

[0151] In other solutions, the limiting rib 111 can also be a plate-like structure.

[0152] The solution of this embodiment further includes: the display device further includes a protective cover 112;

[0153] The protective cover 112 covers the outer periphery of the imaging structure, and a buckle structure 1124 is provided on the protective cover 112, and a mounting opening is provided on the mounting plate, and the buckle structure 1124 passes through the mounting opening for fixation.

[0154] Such as Figure 9As shown, in this solution, the display device further includes a protective cover 112. The protective cover 112 is a semi-enclosed structure formed by at least three surfaces. Specifically, the protective cover 112 includes a top surface 1121 and two side surfaces that extend vertically downward at both ends of the top surface 1121. The length inside the top surface 1121 is equal to the length of the prism 2, and the height of the side surfaces is equal to the height of the prism 2. At least one snap structure 1124 is respectively provided at the extension ends of the two side surfaces, and at least one mounting opening is respectively provided at both ends of the second mounting plate 102. After the protective cover 112 covers the prism 2, the snap structures 1124 on the two side surfaces respectively pass through the corresponding mounting openings to fix the prism 2.

[0155] In this solution, extension portions 1125 are further provided on the two side surfaces of the protective cover 112, and openings are respectively provided at both ends of the second mounting plate 102. The extension portions 1125 are inserted into the openings for limit fixation.

[0156] In the preferred solution of this embodiment, the side surfaces of the protective cover 112 include a first side surface 1122 and a second side surface 1123 that are connected. The first side surface 1122 is connected to the top surface 1121, and the width of the first side surface 1122 is greater than the width of the second side surface 1123. Among them, one ends of the first side surface 1122 and the second side surface 1123 close to the first mounting plate 101 are coplanar, and the ends far from the first mounting plate 101 are non-coplanar. In this solution, the width of the second side surface 1123 is equal to the width of the prism 2. When the prism 2 and the protective cover 112 are installed in place, the limit ribs 111 respectively abut against the rear end of the second side surface 1123 and the lower end of the first side surface 1122.

[0157] It should be noted that when the imaging structure is a cube structure formed by splicing two transparent right-angled triangular prisms, the first side surface of the protective cover abuts against the right-angled surface of one of the right-angled triangular prisms, and the two second side surfaces respectively abut against and are fixedly connected to the two end surfaces at both ends of the two right-angled triangular prisms. In this solution, in order to make the fixation between the protective cover and the prism more firm, the contact parts of the two are fixed by gluing.

[0158] When the imaging structure is a transparent right-angled triangular prism, in this solution, the first side surface of the protective cover abuts against the right-angled surface of the right-angled triangular prism, one second side surface abuts against and is fixedly connected to one end surface of the right-angled triangular prism and one end surface of the support member, and the other second side surface abuts against and is fixedly connected to the other end surface of the right-angled triangular prism and the other end surface of the support member. In this solution, in order to make the fixation between the protective cover and the prism more firm, the contact parts of the protective cover with the right-angled triangular prism and the support member are all fixed by gluing.

[0159] In the solution provided in this embodiment, by providing the protective cover 112 outside the prism 2, the periphery of the prism 2 is prevented from being damaged by external forces.

[0160] The solution of this embodiment further includes: there is a caulking groove on the upper surface of the mounting plate, and glue is applied to the inner surface of the caulking groove and the bottom of the imaging structure for sealed connection.

[0161] In this solution, there is a caulking groove on the upper surface of the mounting plate, and the convex structure is arranged on the inner surface of the caulking groove. During use, glue is applied to both the inner surface of the caulking groove and the bottom of the imaging structure, so that the mounting plate and the prism 2 are not only connected through the limiting structure, but also sealed and connected through glue.

[0162] In a specific solution, the two side walls of the groove-shaped structure 109 on the mounting plate along its length direction respectively have a certain space with the front side and the rear side of the mounting plate. And glue is also applied in this space, increasing the area of the inner surface covered by the glue.

[0163] In this solution, glue is applied to the inner surface of the caulking groove and the bottom of the prism 2 for sealed connection between the two. It effectively prevents water from entering the bottom of the imaging structure along the gap, thus leaving marks and affecting the display interface.
