[0057] As explained in the background section, lawnmowers in the relevant technology have the problem of limited display functions. Research by technicians has revealed that the reason for this problem is that in the existing technology, lawnmowers only have a very small screen for displaying minimalist prompts.

[0058] To address the aforementioned technical problems, this application provides a display device comprising: a dot matrix screen and a light-emitting component, wherein the light-emitting component is disposed around the outer periphery of the dot matrix screen, and the area surrounded by the light-emitting component is the display area of ​​the dot matrix screen; the display device further comprises a display panel, on which patterns displayed individually or in combination by the dot matrix screen and the light-emitting component are realized; the display device is detachably connected to a lawnmower and has rich display functions.

[0059] Meanwhile, the display device provided in this application embodiment also includes: a heat sink, with the display panel and the heat sink fastened together to form an enclosing space, and the dot matrix screen and the light-emitting component both disposed within the enclosing space. The dot matrix screen dissipates heat through the heat sink, but the heat in the heat sink will continuously accumulate in the lawnmower and cannot be dissipated; therefore, the display device provided in this application embodiment also includes: a decorative ring, which is connected to the outer periphery of the display panel, or connected between the display panel and the heat sink, and the decorative ring is provided with a ring of evenly distributed heat dissipation holes, so that the heat on the heat sink can be dissipated upward through the heat dissipation holes, avoiding heat accumulation.

[0060] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0061] This application provides a display device, with reference to... Figures 1 to 5 , Figure 1 This is a schematic diagram of the top structure of the display device provided in the embodiments of this application. Figure 2 This is a schematic diagram of the bottom structure of the display device provided in the embodiments of this application. Figure 3Exploded view of the display device provided in the embodiments of this application Figure 1 , Figure 4 for Figure 3 An enlarged view of part A in the middle. Figure 5 for Figure 3 Enlarged view of section B. This display device is designed to be mounted on a lawnmower, enabling interaction between the user and the machine and enhancing the lawnmower's intelligence.

[0062] The display device includes a display panel 100, a dot matrix screen 300, and a light-emitting component 200. The display panel 100 is formed by a top wall and an annular side wall. The bottom of the display panel 100 has an opening to form a mounting chamber within the display panel 100. The dot matrix screen 300 and the light-emitting component 200 are both disposed in the mounting chamber of the display panel 100 through the bottom opening, with the dot matrix screen 300 located in the central area and the light-emitting component 200 arranged around the outer periphery of the dot matrix screen 300.

[0063] The display pattern of the dot matrix screen 300 is implemented by the dot matrix screen 300 alone, and the display pattern of the dot matrix screen 300 is finally implemented on the top outer surface of the display panel 100, which facilitates human-computer interaction.

[0064] The display pattern of the dot matrix screen 300 can also be achieved by combining the dot matrix screen 300 and the light-emitting component 200.

[0065] It should be noted that the top outer surface of the display panel 100 is glossy and without etching, which ensures that the luminous pattern is displayed delicately and without blurring.

[0066] The display device also includes: a decorative ring 400, which is connected to the outer periphery of the display panel 100 to shield and protect the light-emitting component 200; and a dot matrix screen 300 exposed at the bottom of the display panel 100 through the annular hole of the decorative ring 400.

[0067] The decorative ring 400 is provided with multiple heat dissipation holes 404, which are evenly arranged around the side wall of the display panel 100. The heat from the heat sink 500 will be evenly dissipated from the bottom of the display panel 100 to the top of the display panel 100 from the heat dissipation holes 404.

[0068] In this embodiment of the application, the display device further includes: a heat sink 500, the display panel 100 and the heat sink 500 being fastened together to form an enclosing space, and the dot matrix screen 300 and the light-emitting component 200 being disposed within the enclosing space.

[0069] In one example, a decorative ring 400 can be connected between the display panel 100 and the heat sink 500. The decorative ring 400 is connected to the bottom of the display panel 100 and faces the light-emitting component 200 to shield and protect the light-emitting component 200. The dot matrix screen 300 is exposed at the bottom of the display panel 100 through the annular hole of the decorative ring 400.

[0070] The heat sink 500 passes through the annular hole of the decorative ring 400 and is connected to the bottom of the display panel 100. The heat sink 500 is also in direct contact with the dot matrix screen 300 to dissipate heat from the dot matrix screen 300. The heat sink 500 is also used to enclose the dot matrix screen 300 inside the display panel 100, so that the heat sink 500 can dissipate heat from the dot matrix screen 300 while also protecting the dot matrix screen 300.

[0071] When the decorative ring 400 is connected to the bottom of the display panel 100, the outer edge of the decorative ring 400 surrounds the outer surface of the side wall of the display panel 100. The outer edge of the decorative ring 400 is provided with a plurality of heat dissipation holes 404. The plurality of heat dissipation holes 404 are evenly arranged around the side wall of the display panel 100, and the heat of the heat sink 500 will be evenly dissipated from the bottom of the display panel 100 from the heat dissipation holes 404 to the top of the display panel 100 from bottom to top.

[0072] In another example, the decorative ring 400 can also be attached to the outer periphery of the display panel 100. The decorative ring 400 surrounds the outer surface of the side wall of the display panel 100. The outer edge of the decorative ring 400 is provided with a plurality of heat dissipation holes 404. The plurality of heat dissipation holes 404 are evenly arranged around the side wall of the display panel 100. The heat of the heat sink 500 will be evenly dissipated from the bottom of the display panel 100 from the heat dissipation holes 404 to the top of the display panel 100 from bottom to top.

[0073] The heat sink 500 is connected to the bottom of the display panel 100 and is in direct contact with the dot matrix screen 300 to dissipate heat from the dot matrix screen 300. The heat sink 500 is also used to enclose the dot matrix screen 300 and the light-emitting component 200 inside the display panel 100, so that the heat sink 500 can dissipate heat from the dot matrix screen 300 while also protecting the dot matrix screen 300 and the light-emitting component 200.

[0074] The display device provided in this application embodiment includes: a display panel 100, a dot matrix screen 300, a light-emitting component 200, a decorative ring 400, and a heat sink 500. The dot matrix screen 300 and the light-emitting component 200 are both disposed within the display panel 100, with the light-emitting component 200 surrounding the dot matrix screen 300. The display pattern of the dot matrix screen 300 is implemented solely on the top outer surface of the display panel 100 by the dot matrix screen 300, or the display pattern of the dot matrix screen 300 is implemented by a combination of the dot matrix screen 300 and the light-emitting component 200 on the top outer surface of the display panel 100; the decorative ring 400 connects... At the bottom of the display panel 100, the light-emitting component 200 is shielded and protected, while the dot matrix screen 300 is exposed at the bottom of the display panel 100 through the annular hole of the decorative ring 400. The heat sink 500 is connected to the bottom of the display panel 100 through the annular hole and contacts the dot matrix screen 300. The outer edge of the decorative ring 400 surrounds the outer surface of the side wall of the display panel 100, and multiple heat dissipation holes 404 are provided on the outer edge of the decorative ring 400. The heat generated by the heat sink 500 is dissipated from the bottom of the display panel 100 through the heat dissipation holes 404 to the top of the display panel 100. By setting the decorative ring 400 to protect the dot matrix screen 300 and the light-emitting component 200 disposed inside the display panel 100, and by providing a ring of evenly distributed heat dissipation holes 404 on the decorative ring 400, the heat on the heat sink 500 can be dissipated upward through the heat dissipation holes 404, preventing heat accumulation.

[0075] In this embodiment of the application, the distance between the light-emitting component 200 and the edge of the display area is less than 1 cm in the top-view projection direction.

[0076] In this embodiment, the display panel 100 is transparent or semi-transparent.

[0077] In this embodiment, an auxiliary plate 402 extends outward from the outer edge of the decorative ring 400. The auxiliary plate 402 has multiple heat dissipation holes 404. The auxiliary plate 402 also has multiple protrusions 403, with a gap between adjacent protrusions 403 to form a serrated structure on the auxiliary plate 402. Each heat dissipation hole 404 corresponds to a gap, meaning there is a heat dissipation hole 404 between two adjacent protrusions 403. When heat from the heat sink 500 flows out from the bottom of the display panel 100 through the heat dissipation holes 404, the protrusions 403 guide the heat flow, ultimately causing the heat to dissipate upwards.

[0078] refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of the dot matrix screen of the display device provided in the embodiments of this application; in the embodiments of this application, the dot matrix screen 300 includes a dot matrix screen body 301, a dot matrix screen light-blocking component 302, a light-diffusing film 303, and a first connecting component 801, located in the direction from the bottom of the display panel 100 toward the top of the display panel 100.

The light-diffusing film 303 is attached to the dot matrix screen light-blocking component 302, and the light-diffusing film 303 is close to the top outer surface of the display panel 100.

[0079] The dot matrix screen body 301 consists of 392 monochrome LEDs arranged in a matrix, with each LED individually controlled by a controller to change the displayed content. The dot matrix screen light-blocking component 302 is a black, opaque structure to prevent light leakage. The light-diffusing film 303 is a semi-transparent film, made of gray or dark gray, which, while achieving uniform light distribution for each LED, reduces the contrast difference with the display panel's colors, resulting in a more seamless appearance. Furthermore, the internal structure is not visible when the screen is off, and it absorbs some light leakage.

[0080] Meanwhile, the display panel 100 is also provided with a third connection hole. The first connector 801 is connected to the first connection hole 3011, the second connection hole 3021 and the third connection hole, so that the dot matrix screen 300 is assembled in the display panel 100.

A second abutting protrusion 1021 is provided on the side of the second annular plate 102 near the connecting plate 406 to abut against the first abutting protrusion 4061, thus ensuring the connection between the decorative ring 400 and the display panel 100.

[0089] Continue to refer to Figure 3 , Figure 4 and Figure 8 In this embodiment of the application, the light-emitting component 200 includes an annular light strip and an annular light-diffusing strip 201. On the direction from the bottom of the display panel 100 toward the top of the display panel 100 (the direction from bottom to top shown in the figure), the annular light strip and the annular light-diffusing strip 201 are stacked in sequence in the second mounting chamber, and the annular light-diffusing strip 201 is in contact with the inner wall surface of the top of the display panel 100; that is, the annular light-diffusing strip 201 is disposed on the annular light strip to ensure uniform light emission.

[0090] In the above embodiment, the annular light strip is a first annular light strip 202, which includes a silicone sleeve and a light strip. The light strip is set in the silicone sleeve.
