Description

Technical Field

[0001] This invention belongs to the field of household appliances, specifically, it relates to a display device for a household appliance and the household appliance itself. Background Technology

[0002] Currently, common household appliances typically have a control panel for receiving control commands and a display screen for showing images, such as washing machines and range hoods. Taking washing machines as an example, the display screen and control panel of a conventional washing machine are displayed on the same plane. In actual products, to facilitate users issuing control commands on the control panel, it is usually set horizontally. When users want to view the displayed content, they need to walk closer to the display screen. In other words, users cannot observe the displayed content from a distance, resulting in a limited field of view and impacting the user experience.

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

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a display device and household appliance in which the display structure is fixed above the display area on the control panel by a limiting structure, and the display surface of the display structure is set at a certain angle to the control plane, so that the user can see the display content of the display area through the display structure even when there is a certain distance between the user and the display area.

[0005] To solve the above-mentioned technical problems, 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] The display device includes: a control panel having a connected operating area and a display area;

[0008] The display structure is disposed above the display area and has a display surface at a certain angle to the operation plane where the operation area is located. The display content in the display area can be projected onto the display surface for display.

[0009] The display area of ​​the display structure and / or the control panel is provided with a limiting structure for fixing the display structure.

[0010] The display device provided by this invention includes a control panel and a display structure. The display structure is positioned above the display area on the control panel via a limiting structure, and the display content of the display area is displayed through the display structure. During installation, for ease of user operation, the operating plane is typically set horizontally. However, in this design, because there is a certain angle between the display surface and the operating plane, the user can observe the display content of the display area through the display surface of the display structure, thereby increasing the user's field of view and improving the user experience.

[0011] Furthermore, the limiting structure includes a protrusion structure disposed above the control panel and a groove structure disposed at the bottom of the display structure; the protrusion structure is inserted into the groove structure for limiting engagement.

[0012] Furthermore, the control panel includes a mounting plate, and a control screen and a display screen mounted on the mounting plate;

[0013] The control panel is installed in the operation area, and the display screen is installed in the display area;

[0014] The imaging structure is mounted on the upper surface of the mounting plate, at least covering the display screen.

[0015] Furthermore, at least the mounting plate of the display area has a certain thickness and has an upward-opening groove structure, in which the display screen is installed.

[0016] Furthermore, at least two protrusions are symmetrically arranged in the lower region of the sidewall of the groove structure, with the upper end of the protrusions being lower than the upper surface of the mounting plate, and the display screen is mounted above the protrusions.

[0017] Furthermore, the protruding structure is formed by the upper part of the sidewall of the groove structure protruding from the upper surface of the mounting plate.

[0018] Furthermore, the upper surface of the mounting plate has a glue-applying groove, and glue is applied to the inner surface of the glue-applying groove and the bottom of the imaging structure for sealing connection.

[0019] Furthermore, the display area of ​​the control panel is provided with a limiting rib on the side away from the operation area, which cooperates with the stop of the display structure.

[0020] Furthermore, the display device also includes a protective cover;

[0021] The protective cover is installed around the outer periphery of the display structure, and the protective cover is provided with a buckle structure. The mounting plate is provided with a mounting port, and the buckle structure passes through the mounting port for fixation.

[0022] On the other hand, a household appliance is also provided. The household appliance includes the display device of the aforementioned household appliance.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] 1. The display device provided by the present invention has an imaging structure positioned above the display area on the control panel via a limiting structure, and the display content of the display area is displayed through the imaging structure. During installation, to facilitate user operation, the operating plane is typically set horizontally. However, in this solution, because there is a certain angle between the display surface and the operating plane, the user can observe the display content of the display area through the display surface of the imaging structure, thereby increasing the user's field of view and improving the user experience.

[0025] 2. The display device provided by the present invention includes a limiting structure consisting of a protruding structure on the upper surface of the mounting plate and a groove structure on the bottom of the display structure. The two structures work together to securely fix the display structure.

[0026] 3. The display device provided by the present invention, since the display screen is installed in the through hole and the imaging structure is installed on the upper surface of the mounting plate, ensures that the weight of the imaging structure will not directly act on the display screen and crush it.

[0027] 4. The display device provided by the present invention seals the connection between the upper surface of the mounting plate and the bottom of the display structure by adhesive fixing, thereby preventing water from entering the bottom of the display structure along the gap and leaving marks that affect the display interface.

[0028] 5. The display device provided by the present invention, by setting limiting ribs, makes the display structure and the mounting plate more firmly fixed.

[0029] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0053] like Figures 1 to 11 As shown, the present invention provides a display device for a household appliance and a household appliance.

[0054] The display device includes:

[0055] Control panel 1 has a connected operating area and display area;

[0056] The display structure is disposed above the display area and has a display surface 201 at a certain angle to the operation plane where the operation area is located. The display content in the display area can be projected onto the display surface 201 for display.

[0057] The display structure and / or the display area of ​​the control panel 1 are provided with a limiting structure for fixing the display structure.

[0058] The display device provided by the present invention has a certain angle between the display surface and the operation plane, which allows the user to observe the display content of the display area through the display surface of the display structure, thereby increasing the user's field of view and improving the user experience.

[0059] On the other hand, a household appliance is also provided, which includes the display device of the aforementioned household appliance.

[0060] Example 1

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

[0062] The display device includes:

[0063] Control panel 1 has a connected operating area and display area;

[0064] The display structure is disposed above the display area and has a display surface 201 at a certain angle to the operation plane where the operation area is located. The display content in the display area can be projected onto the display surface 201 for display.

[0065] The display structure and / or the display area of ​​the control panel 1 are provided with a limiting structure for fixing the display structure.

[0066] In this embodiment, the household appliances are appliances such as washing machines and range hoods that have an operating area and a display area. In this embodiment, a washing machine will be used as an example for explanation.

[0067] In this design, the washing machine's display device includes a control panel 1 and an image display structure, and the image display structure and the control panel 1 are fixedly connected by a limiting structure. The limiting structure may be provided only on the image display structure, only on the control panel 1, or both the image display structure and the control panel 1 may have limiting structures.

[0068] The control panel 1 has an interconnected operating area and a display area. In use, the user can control the operating area to send control commands to the washing machine, while the display area can show images of relevant information during the washing process, such as the current washing program, washing temperature, and remaining washing time.

[0069] The display structure is positioned above the display area and has a display surface 201. The display surface 201 is at a certain angle to the operating plane. In use, the content displayed in the display area can be projected onto the display surface 201 for display, allowing the user to access washing-related information.

[0070] The display device provided in this embodiment has a certain angle between the display surface and the operating plane, which allows the user to observe the display content on the screen through the display surface of the imaging structure, thereby increasing the user's field of view and improving the user experience.

[0071] In one specific 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.

[0072] Specifically, the control panel 1 includes a mounting plate, and a control screen 104 and a display screen 103 disposed on the mounting plate;

[0073] The control panel 104 is installed in the operation area, and the display screen 103 is installed in the display area;

[0074] The display structure is mounted on the upper surface of the mounting plate and at least covers the display screen 103.

[0075] In this design, the control panel 1 includes a mounting plate, and a display screen 103 and a control panel 104 mounted on the mounting plate. The control panel 104 displays text corresponding to control commands, and the display screen 103 displays graphic information. The mounting plate comprises two parts: a first mounting plate 101 and a second mounting plate 102. The first mounting plate 101 has an operating area, on which the control panel 104 is mounted. The second mounting plate 102 has a display area, on which the display screen 103 is mounted. The display structure is mounted on the upper surface of the second mounting plate 102 above the display screen 103.

[0076] In this scheme, the first mounting plate 101 and the second mounting plate 102 are not on 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 on the same plane and there is an angle between them.

[0077] In one specific embodiment, the mounting plate is a one-piece molded 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 embodiment, the mounting plate is not a one-piece structure. The first mounting plate 101 and the second mounting plate 102 are connected by a pivot, 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 placed on the same plane, the area of ​​the control screen 104 and the display screen 103 is increased, allowing the fonts on the control screen 104 and the patterns on the display screen 103 to be freely designed, thereby improving the user experience.

[0080] In another specific embodiment, the operating plane of the control panel and the display plane of the display area are on the same plane. In this embodiment, the display screen and control screen are separate, but both are located on the same plane. For example, both the display screen and control screen are horizontally positioned, with the display device mounted above the display screen. The display surface of the display device is at an angle to the control screen, which can be 90 degrees. That is, the display surface is perpendicular to the control screen, so the user does not need to walk to the location of the display screen to observe its content; they can see the displayed content from a distance through the display surface of the display device. This increases the user's field of view and improves the user experience.

[0081] In this embodiment, the display structure is a prism 2 made of a transparent material. The prism 2 is made of any transparent material, such as glass, crystal, or acrylic.

[0082] In one specific embodiment, the imaging structure is a right-angled triangular prism structure.

[0083] In this design, the right-angle prism has two right-angled surfaces and one inclined surface. One right-angled surface serves as the recognition surface 202, the other right-angled surface serves as the display surface 201, and the inclined surface serves as the reflecting surface 203.

[0084] During installation, one right-angled facet of the right-angled prism is mounted on the upper surface of the second mounting plate 102, parallel to and above the display screen 103; this right-angled facet serves as the recognition facet 202. The other right-angled facet is positioned close to the first mounting plate 101, serving as the display facet 201. The inclined surface positioned above the display area serves as the reflective facet 203. Because the right-angled prism 2 is made of transparent material, the display content on the display screen 103, when illuminated, can be refracted through the recognition facet 202 to the reflective facet 203, and then reflected back onto the display facet 201. The user can then see the display content of the display screen 103 on the display facet 201.

[0085] In a further embodiment, since the display structure is a right-angled triangular prism 2, its cross-section is a transparent body with a right-angled triangle. In order to make the display surface 201 better display the image of the display screen 103, the two right-angled sides of the right-angled triangle in the cross-section of the prism are of the same length.

[0086] In a preferred embodiment, to make the image reflected from the reflective surface 203 onto the display surface 201 clearer, a film is applied to the reflective surface 203. This film can be either transparent or opaque. When a transparent film is installed, the user can see the rear view from the front of the prism 2, providing a wider field of view.

[0087] like Figure 7 and Figure 8 As shown, in this scheme, there is an angle between the display screen 103 and the control screen 104, and the angle between them is greater than 180 degrees. Under normal circumstances, in order to facilitate users to issue control commands on the control screen 104, the control screen 104 is usually set in a horizontal direction, while the display screen 103 is set at an angle. In order to better install the prism 2 above the display screen 103, a support member 4 is set behind the right-angle triangular prism.

[0088] In one specific embodiment, the support member, like a right-angle prism, has a certain extended length. It includes a first support plate 401 and a second support plate 402 connected to each other and having a certain included angle. The first support plate is arranged parallel to the recognition surface 202, with one end abutting against the end of the reflective surface 203 away from the recognition surface, and the other end connected to the second support plate 402. The second support plate 402 extends towards the recognition surface 202, and its extended end abuts against the end of the reflective surface 203 near the recognition surface 202.

[0089] In a preferred embodiment, the included angle between the first support plate 401 and the second support plate 402 is 90 degrees.

[0090] In a further embodiment, the support member further includes a third support plate 403 connecting the first support plate 401 and the second support plate 402. To make the support of the first support plate 401 and the second support plate 402 more stable, the third support plate 403 is inclined, so that the three support plates form a stable triangular prism structure. In this embodiment, the third support plate 403 is abutted against the reflecting surface 203 of the prism.

[0091] In a further embodiment, the second mounting plate includes a first panel and a second panel perpendicular to the first panel. The second panel is located at the end away from the first mounting plate. The display screen 103 and the prism 2 are mounted on the first panel. In a specific embodiment, a latching protrusion 405 is provided on the outer side of the second support plate, and the latching protrusion 405 latches onto the upper end of the second panel.

[0092] In a further embodiment of this invention, the support member further includes a fourth support plate 404.

[0093] In this specific embodiment, the first support plate extends from its connection point with the second support plate in a direction away from the display surface, and a fourth support plate is connected to the extended end. The other end of the fourth support plate extends downward at an angle, and the extended end abuts against the fixing frame of the fixed control panel. That is, the second support plate 402 is disposed between the first support plate 401 and the fourth support plate 404.

[0094] In this solution, the display device further includes a mounting bracket 5, which includes a first mounting plate 501 with a certain thickness. The first mounting plate 501 is supported on the cover of the household appliance, and its other end extends obliquely toward the first support plate of the support member. At its extended end, a second mounting plate 502 is provided, which is perpendicular to the first mounting plate 501 and extends toward the second support plate on the support member. At the extended end of the second mounting plate 502, a third mounting plate 503 is provided, which is perpendicular to the second mounting plate and extends toward the first support plate on the support member. At the extended end of the third mounting plate 503, a fourth mounting plate 504 is provided, which is perpendicular to the third mounting plate and extends toward the second support plate on the support member. At the extended end of the fourth mounting plate 504, a fifth mounting plate 505 is provided, which is perpendicular to the fourth mounting plate and extends away from the first support plate on the support member. At the extended end of the fifth mounting plate 505, a sixth mounting plate 506 is provided, which is parallel to the second mounting plate. The outer side of the second mounting plate 402 abuts against the sixth mounting plate 506.

[0095] The other end of the fourth support plate 404 is fastened to 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, the first fixing plate 501 and the third support plate 403 are arranged parallel to each other.

[0096] It is worth noting that in this scheme, the angle between the first support plate and the fourth support plate is greater than 90 degrees and less than 180 degrees.

[0097] In one specific embodiment, the support member comprises several spaced-apart support members, with the third support plate 403 of each support member abutting against the reflecting surface 203 of the right-angled triangular prism. To ensure a more secure fixation between the support member 4 and the right-angled triangular prism 2, adhesive is applied between the third support plate 403 of the support member and the reflecting surface 203 of the right-angled triangular prism. Furthermore, in this embodiment, the width of the support plate in each support member is the same. End faces are provided at the two outward-facing ends of the two support members at both ends of the support member.

[0098] It is worth noting that in the above scheme, the support is a hollow structure made of support plates, and the first support plate, the second support plate, the third support plate and the fourth support plate are all long strip-shaped plate structures.

[0099] like Figure 7 As shown, in a preferred embodiment, the third support plate has spaced square holes.

[0100] In a further design, the spacing between the square holes can be the same or different. The specific spacing method is not limited in this design.

[0101] In other specific embodiments of this invention, the support member may also be a solid structure.

[0102] In another embodiment, the imaging structure is a cuboid structure formed by the inclined surfaces of two identical right-angled triangular prisms 2 touching each other.

[0103] In this scheme, the imaging structure is no longer a transparent prism, but a cubic structure composed of two transparent right-angled prisms. Specifically, the imaging structure is a cubic structure formed by the inclined surfaces of two identical right-angled prisms touching each other, and an opaque film is covered on the reflective surface 203 of the right-angled prism where the display surface 201 is located.

[0104] Because the display structure is a prism 2, the pattern on the display screen 103 has a three-dimensional effect after being reflected by the prism 2, which can transform the original flat image into a three-dimensional pattern, making it more vivid and lifelike.

[0105] In another specific embodiment, the imaging structure is a transparent cubic prism 2, and a coating is applied to the diagonal surfaces of the cubic prism 2.

[0106] The solution in this embodiment also includes: the angle between the operating plane and the display plane is greater than 180 degrees.

[0107] In the above scheme, 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 on the same plane, and the included angle between them is greater than 180 degrees. Furthermore, since the display structure is set 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. Thus, the angle between the display surface 201 and the control screen 104 is greater than 90 degrees, providing the user with a wider field of view.

[0108] The display device provided in this embodiment breaks with conventional assembly schemes by placing the display screen 103 and the control screen 104 on different planes, thereby greatly increasing the space of the operation area and display area and fundamentally solving the problems of insufficient interface space and compact layout. This improves the user experience.

[0109] like Figures 3 to 6 As shown, the solution of this embodiment also includes: at least the mounting plate of the display area has a certain thickness and has an upward-opening groove structure 109, and the display screen 103 is installed in the groove structure 109.

[0110] Furthermore, at least two protrusions 110 are symmetrically arranged in the lower region of the sidewall of the groove structure 109, the upper end of the protrusions 110 being lower than the upper surface of the mounting plate, and the display screen 103 being mounted above the protrusions 110.

[0111] The protruding structure is formed by the upper part of the sidewall of the groove structure protruding from the upper surface of the mounting plate.

[0112] In this design, the second mounting plate 102 is a rectangular structure with a certain extension length and a certain thickness. The second mounting plate 102 has an upward-opening groove structure 109. The groove structure 109 includes a first groove structure 1091 and a second groove structure 1092 disposed in the middle region of the first groove structure 1091.

[0113] like Figure 11 As shown, to prevent moisture from entering the recognition surface of the imaging structure, a protrusion is provided on the recognition surface of the right-angled triangular prism, and the protrusion is embedded in the first groove structure.

[0114] In this specific embodiment, the second groove structure 1092 has the same shape as the display screen 103, both being rectangular structures. The size of the second groove structure 1092 is also the same as or slightly larger than the size of the display screen 103.

[0115] The second groove-shaped structure 1092 has four side walls and a bottom wall, namely symmetrical front and rear side walls, left and right side walls, and a bottom wall disposed below. Protrusions 110 are provided on at least one set of symmetrical side walls. For example, two protrusions 110 are symmetrically provided on the front and rear side walls, or two protrusions 110 are symmetrically provided on the left and right side walls.

[0116] In this specific embodiment, to more securely fix the display screen 103, multiple protrusions 110 are provided on each of the four side walls of the second groove structure 1092. More specifically, the protrusions 110 are all located in the lower region 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, the upper ends of the protrusions 110 are a certain distance from the upper end of the groove structure 1092. During installation, the display screen 103 is placed in the groove structure 1092, and the lower surface of the display screen 103 abuts against the upper end face of the protrusions 110. In other words, in this embodiment, the display screen 103 is fixed in the second groove structure 1092 by the protrusions 110 provided on the side walls of the second groove structure 1092.

[0117] In a more specific embodiment, the display screen includes a PCB display board, a sponge, and a color filter. The PCB display board is located at the bottom and is fixed in contact with the protrusion, while the sponge and color filter are sequentially installed above the PCB display board.

[0118] In another embodiment, no protrusions 110 are provided on the side wall of the groove structure 109, and the display screen 103 is placed directly in the second groove structure 1092 and abuts against the bottom wall of the second groove structure 1092.

[0119] In another embodiment, the second mounting plate 102 is also a plate-like structure with a certain thickness, but instead of grooves, it has through holes, and protrusions 110 are provided on the sidewalls of the through holes. In use, the display screen 103 is placed into the through holes for fixation.

[0120] In a preferred embodiment, since the display screen 103 has a certain thickness, and the display structure is disposed on the inner surface of the second mounting plate 102, in order to prevent the gravity of the display structure from directly acting on the display screen 103 and crushing it, after 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.

[0121] In this embodiment, since the imaging structure is a prism 2 made of transparent glass with a smooth outer surface, it is not easy to fix it to 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 make the prism 2 more firmly fixed to the second mounting plate 102.

[0122] like Figure 4 As shown, specifically, the limiting structure includes a protrusion structure on the upper surface of the second mounting plate 102 and a groove structure on the bottom of the prism 2. When the prism 2 is placed on the second mounting plate 102, the protrusion structure on the second mounting plate 102 inserts into the groove structure at the bottom of the prism 2 to limit and fix the two.

[0123] More specifically, the protruding structure includes a first protruding structure 105 and a second protruding structure 106. Correspondingly, the groove structure also includes a first groove structure 107 corresponding to the first protruding structure 105, and a second groove structure 108 corresponding to the second protruding structure 106.

[0124] The first protruding structure 105 is formed by the upper part of the sidewall of the second groove structure 1092 protruding from the upper surface of the mounting plate. Since the through hole has four sidewalls, the first protruding structure 105 is a square frame formed by four protruding lines connected end to end. The second protruding structure 106 is a protruding line perpendicular to the extending direction of the second mounting plate 102.

[0125] In one specific embodiment, a first protruding structure 105 is provided, and two second protruding 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 protruding structure 105 is located at the middle position of the second mounting plate 102, and a second protruding structure 106 is provided on each side of the first protruding structure 105.

[0126] like Figure 10 As shown, the first groove structure 107 is located in the middle area of ​​the bottom of the prism 2, and it is a square frame structure formed by four groove lines connected end to end. The second groove structure 108 is located at the left and right ends of the bottom of the prism 2, and is perpendicular to the groove lines along the length of the prism 2.

[0127] In other specific solutions of this embodiment, the extension direction of the second limiting rib 111 can be other directions, and the number of second limiting ribs 111 can also be other numbers, which are not specifically limited here.

[0128] Of course, to make the connection between the prism 2 and the second mounting plate 102 more secure, the depth of the groove structure and the protrusion height of the protrusion structure can be increased. The area of ​​the groove structure on the second mounting plate 102 and the area of ​​the protrusion structure at the bottom of the prism 2 can also be increased.

[0129] In a further embodiment, the first groove structure and the second groove structure are disposed on the protrusion 204.

[0130] The solution in this embodiment also includes: the display area of ​​the control panel 1 is provided with a limiting rib 111 that cooperates with the stop of the display structure on the side away from the operation area.

[0131] To facilitate user input of control commands on the control panel 104, the control panel 104 is generally positioned horizontally. Since the angle between the first mounting plate 101 and the second mounting plate 102 is greater than 180 degrees, meaning the second mounting plate 102 is tilted downwards relative to the horizontal, the prism 2 on the second mounting plate 102 is prone to slipping off. To prevent the prism 2 from slipping off the second mounting plate 102, a limiting rib 111, which cooperates with the stop of the display structure, is provided on the side of the second mounting plate 102 away from the first mounting plate 101.

[0132] In this design, the limiting rib 111 is also a triangular prism structure with a right-angled triangle cross-section. The limiting rib 111 and the second mounting plate 102 are not integrally formed. The bottom of the limiting rib 111 has a snap-fit ​​portion, and the second mounting plate 102 has a snap-fit ​​groove. After the protrusion on the second mounting plate 102 is properly positioned and engaged with the groove on the prism 2, the snap-fit ​​portion on the limiting rib 111 is aligned with the snap-fit ​​groove on the second mounting plate 102 and inserted, thus fixing the limiting rib 111 onto the second mounting plate 102. In this design, the imaging structure is a cubic structure composed of two transparent right-angled triangular prisms 2. After the limiting rib 111 is installed in place, it fixes the imaging structure by abutting against the right-angled surface of one of the prisms 2.

[0133] Of course, in other embodiments of this invention, the limiting rib 111 and the second mounting plate 102 can also be fixedly connected in other ways, or they can be an integrally formed structure.

[0134] In other designs, the limiting rib 111 can also be a plate-like structure.

[0135] The solution in this embodiment also includes: the display device further includes a protective cover 112;

[0136] The protective cover 112 is provided on the outer periphery of the display structure, and the protective cover 112 is provided with a buckle structure 1124. The mounting plate is provided with a mounting port, and the buckle structure 1124 passes through the mounting port for fixation.

[0137] like Figure 9 As shown, in this solution, the display device also includes a protective cover 112. The protective cover 112 is a semi-enclosed structure consisting of at least three surfaces. Specifically, the protective cover 112 includes a top surface 1121 and two side surfaces extending downwards perpendicularly from both ends of the top surface 1121. The length of the inner side of 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-fit ​​structure 1124 is provided at the extended ends of each of the two side surfaces, and at least one mounting opening is provided at each end of the second mounting plate 102. After the protective cover 112 covers the prism 2, the snap-fit ​​structures 1124 on the two side surfaces pass through the corresponding mounting openings to fix the prism 2.

[0138] In this design, extensions 1125 are provided on two sides of the protective cover 112, and openings are provided at both ends of the second mounting plate 102. The extensions 1125 are inserted into the openings for positioning and fixation.

[0139] In a preferred embodiment, the protective cover 112 includes a first side surface 1122 and a second side surface 1123 connected to each other. 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. The ends of the first side surface 1122 and the second side surface 1123 closest to the first mounting plate 101 are coplanar, while the ends furthest from the first mounting plate 101 are not coplanar. In this embodiment, the width of the second side surface 1123 is equal to the width of the prism 2. After the prism 2 and the protective cover 112 are installed in place, the limiting rib 111 abuts against the rear end of the second side surface 1123 and the lower end of the first side surface 1122, respectively.

[0140] It is worth noting that when the imaging structure is a cuboid structure composed of two transparent right-angled prisms, the first side of the protective cover abuts against the right-angled face of one of the right-angled prisms, and the two second sides abut against and are fixedly connected to the two end faces of the two right-angled prisms respectively. In this design, to make the fixation between the protective cover and the prisms more secure, the contact points are sealed with adhesive.

[0141] When the imaging structure is a transparent right-angled prism, in this design, the first side of the protective cover abuts against the right-angled face of the prism, one second side abuts against and is fixedly connected to one end face of the right-angled prism and one end face of the support unit, and the other second side abuts against and is fixedly connected to the other end face of the right-angled prism and the other end face of the support unit. In this design, to make the fixation between the protective cover and the prism more secure, the contact points between the protective cover and the right-angled prism and the support are all fixed with adhesive.

[0142] In the solution provided in this embodiment, a protective cover 112 is provided outside the prism 2 to prevent the prism 2 from being damaged by external forces.

[0143] The solution in this embodiment further includes: having a glue-applying groove on the upper surface of the mounting plate, and applying glue to the inner surface of the glue-applying groove and the bottom of the imaging structure for sealing connection.

[0144] In this design, the upper surface of the mounting plate has a glue-applying groove, and the protruding structure is disposed on the inner surface of the glue-applying groove. During use, glue is applied to both the inner surface of the glue-applying groove and the bottom of the imaging structure, so that the mounting plate and the prism 2 are connected not only by the limiting structure but also by the glue for a sealed connection.

[0145] In the specific design, the two sidewalls of the groove-shaped structure 109 on the mounting plate along its length have certain spaces with the front and rear sides of the mounting plate, respectively. Adhesive is also applied within these spaces, increasing the area of ​​the inner surface covered by adhesive.

[0146] In this solution, adhesive is applied to the inner surface of the adhesive application tank and the bottom of prism 2 to create a sealed connection between them. This effectively prevents water from entering the bottom of the imaging structure along the gaps, thus leaving marks and affecting the display interface.
