[0037] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0038] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0039] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0040] For display devices with display modules, the display module is typically fixed to the front housing with bolts, and the circuit board is fixed to the display module. When the display module needs to be replaced or maintained, the old display module must be removed from the front housing, the circuit board removed from the old display module, the new display module assembled with the front housing, and then the circuit board assembled with the new display module. The disassembly and assembly of display devices is time-consuming, costly, and inefficient.

[0041] Based on this, the present disclosure provides a display device. For example... Figures 1 to 7As shown, the display device includes a front shell 11, a display module 12, a first adapter plate 13, and a circuit board 14. The front shell 11 has a first opening 111. The display module 12 is installed in the first opening 111 and protrudes from the outer surface of the front shell 11. The display module 12 includes a display panel 124. The first adapter plate 13 abuts against the side of the display module 12 away from the front shell 11, and the first adapter plate 13 is fixed together with the front shell 11, clamping the display module 12 between the front shell 11 and the first adapter plate 13. The circuit board 14 is fixed to the side of the first adapter plate 13 away from the front shell 11, and the circuit board 14 is electrically connected to the display panel 124.

[0042] The display device includes a front housing 11, a display module 12, a first adapter plate 13, and a circuit board 14. The display module 12 is installed in the first opening 111 and sandwiched between the front housing 11 and the first adapter plate 13. The first adapter plate 13 is fixed to the front housing 11, and the circuit board 14 is fixed to the side of the first adapter plate 13 away from the front housing 11. When the display module 12 needs to be replaced or maintained, the first adapter plate 13 can be removed from the front housing 11 to remove the old display module 12. After replacing the old display module 12, the first adapter plate 13 is fixed to the front housing 11 to install the front frame assembly 1. The disassembly and assembly of the display device is quick, low-cost, and highly efficient.

[0043] The display device involved in the embodiments of this disclosure will be described in detail below with reference to specific examples.

[0044] like Figure 1 As shown, the display device includes a front frame assembly 1, which includes a front housing 11 and a display module 12. The front housing 11 has a first opening 111, and the display module 12 is installed in the first opening 111. The display module 12 may include a lens 121 and a positioning plate 122. The lens 121 is mounted on the positioning plate 122 and protrudes from the outer surface of the front housing 11. The positioning plate 122 is snapped into the inner surface of the front housing 11. The lens 121 may include a lens and a display panel 124. By bringing the eye close to the lens, the display image on the display panel 124 can be seen.

[0045] The display device also includes a first adapter plate 13, the size of which is larger than that of the positioning plate 122. The first adapter plate 13 has positioning protrusions 1221 on two sides extending along the second direction. The positioning protrusions 1221 are located on the side of the first adapter plate 13 away from the front shell 11. The first adapter plate 13 has a positioning groove 131, and the positioning protrusions 1221 are fitted into the positioning groove 131 to determine the relative position of the first adapter plate 13 and the display module 12.

[0046] A connecting post 112 is provided on the inner surface of the front shell 11. The connecting post 112 is located around the positioning plate 122, and the end of the connecting post 112 away from the front shell 11 can be flush with the side of the positioning plate 122 away from the front shell 11. The first adapter plate 13 is attached to the connecting post 112. The connecting post 112 is provided with a connecting hole 1121. The first adapter plate 13 is provided with a mounting hole 132 at the position directly opposite to the connecting hole 1121. A first bolt can be installed through the mounting hole 132 and the connecting hole 1121 to fix the first adapter plate 13 to the front shell 11. The display module 12 is clamped between the front shell 11 and the first adapter plate 13.

[0047] The front frame assembly 1 also includes a cover plate 16, which has a second opening 161 through which the display module 12 passes and protrudes from the side of the cover plate 16 away from the first support section 211. The cover plate 16 is bonded to the side of the front shell 11 away from the first support section 211, and the logo 17 about the display device can be bonded to the side of the cover plate 16 away from the front shell 11.

[0048] The front frame assembly 1 also includes a circuit board 14, which is located on the side of the first adapter plate 13 away from the front housing 11. The side of the first adapter plate 13 away from the front housing 11 is provided with two rows of first fixing posts 133 extending in a first direction. The circuit board 14 and the side of the first fixing posts 133 away from the front housing 11 are attached together. A second bolt can be provided to pass through the circuit board 14 and the first fixing posts 133 to connect the circuit board 14 and the first adapter plate 13.

[0049] The front frame assembly 1 also includes a heat sink 15, which is located on the side of the first adapter plate 13 away from the front shell 11. The side of the first adapter plate 13 away from the front shell 11 is provided with a row of second fixing posts 134 extending in a first direction. The row of second fixing posts 134 is located between the two rows of first fixing posts 133. The heat sink 15 is attached to the side of the first fixing posts 133 away from the front shell 11. A third bolt can be provided to pass through the heat sink 15 and the second fixing posts 134 to connect the heat sink 15 to the first adapter plate 13.

[0050] The length of the second fixing post 134 is less than the length of the first fixing post 133, therefore the heat sink 15 is positioned between the circuit board 14 and the first adapter plate 13. The height difference between the second and first fixing posts 133 can be set to approximately equal the thickness of the heat sink 15, ensuring full contact between the heat sink 15 and the circuit board 14. This allows all the above components to be assembled into the front frame assembly 1, resulting in high assembly efficiency.

[0051] The display device also includes a support component 2, which includes a bracket 21. The bracket 21 includes a first support segment 211 and a second support segment 212. The second support segment 212 intersects with the first support segment 211. The second support segment 212 and the first support segment 211 can be integrally formed. The included angle between the second support segment 212 and the first support segment 211 can be less than 90 degrees.

[0052] like Figures 2 to 4 As shown, the surface of the first support section 211 is provided with a second adapter plate 22. A fourth bolt can be installed to pass through the second adapter plate 22 and the first support section 211 to fix the second adapter plate 22 and the first support section 211 together. The side of the second adapter plate 22 away from the second support section 212 is provided with a first latch 2111, and the side of the first support section 211 away from the second support section 212 is provided with a second latch 221. The latching member 113 passes through the first latch 2111 and the second latch 221, and the latching member 113 is fastened to the second adapter plate 22. The size of the first latch 2111 is smaller than the size of the second latch 221. The orthographic projection of the first latch 2111 on the first support section 211 is located inside the second latch 221 to avoid interference between the first latch 2111 and the latching member 113 after fastening.

[0053] A snap-fit ​​member 113 is provided on the side of the front shell 11 near the first support section 211. The snap-fit ​​member 113 includes a first snap-fit ​​section 1131, a second snap-fit ​​section 1132 and a third snap-fit ​​section 1133 connected in sequence. The first snap-fit ​​section 1131 is connected to the ribs provided on the inner surface of the front shell 11, or it can be directly connected to the inner surface of the front shell 11. The first snap-fit ​​section 1131 and the third snap-fit ​​section 1133 are parallel to the inner surface of the front shell 11, and the second snap-fit ​​section 1132 is perpendicular to the first snap-fit ​​section 1131 and the third snap-fit ​​section 1133.

[0054] When the engagement is complete, the first latching segment 1131 is located on the side of the second adapter plate 22 near the inner surface of the front shell 11, and the third latching segment 1133 is located on the side of the second adapter plate 22 away from the inner surface of the front shell 11. The second latching segment 1132 contacts the side wall of the first latch 2111 of the second adapter plate 22. It can be understood that the orthographic projection of the third latching segment 1133 on the second adapter plate 22 at least partially overlaps with the periphery of the first latch 2111 to prevent the latching member 113 from failing to engage or coming off.

[0055] The front shell 11 has one side extending in a first direction and a second side extending in a second direction. The front shell 11 is engaged with the first support section 211 and the second adapter plate 22 near one of the first sides. The front shell 11 is provided with magnets 18 near the two second sides. The second adapter plate 22 is provided with a mounting groove 222 at the position corresponding to the magnets 18. A magnetic conductive structure can be provided in the mounting groove 222.

[0056] After the front shell 11 is fastened near the first side, the front frame assembly 1 is rotated towards the first support section 211 with the fastening point as the axis. This magnetically attracts the magnets 18 near the two second sides to the magnetic conductive structure on the second adapter plate 22. When separating the front frame assembly 1 from the bracket 21, the front shell 11 is lifted away from the first support section 211. The magnetic force of the magnets 18 on the magnetic conductive structure gradually disappears. At this time, the latching member 113 rotates towards the first support section 211, allowing it to slide along the second latch 221 towards the first latch 2111. This facilitates the disengagement of the latching member 113 from the first support section 2111. To facilitate the insertion and removal of the latching member 113, the side wall of the first latch 2111 can be made into a slope, with the edge of the slope extending towards the edge of the second latch 221.

[0057] like Figure 1 , 2 As shown in Figure 5, the support assembly 2 also includes a rear shell 23, which has a first mating part and a second mating part. The first mating part fits into the first support section 211, and the second mating part fits into the second support section 212. The rear shell 23 and the bracket 21 form a cavity. The third side plate 233 of the rear shell 23 is provided with a wire outlet hole 2331 communicating with the cavity. The first support section 211 is provided with a wire through hole 2112. The wire 3 passes through the wire through hole 2112 and the wire outlet hole 2331 and connects to the circuit board 14. The rear shell 23 includes two first side plates 231, one second side plate 232, and one third side plate 233. The two first side plates 231 are trapezoidal in shape and are spaced apart along a first direction. The second side plate 232 is rectangular and is connected to the side of the first side plate 231 away from the second support section 212. The third side plate 233 is rectangular and is connected to the side of the first side plate 231 and the second side plate 232 away from the first support section 211.

[0058] The display module 12 and circuit board 14 generate a significant amount of heat, resulting in a high internal temperature for the display device. Since the front of the display module 12 is the exterior surface, it's impossible to create heat dissipation holes on it. Therefore, heat dissipation is achieved through the first support section 211 on the back of the display module 12. A first heat dissipation area is provided on the first support section 211, and multiple first heat dissipation holes 2113 are provided within this area. The orthogonal projection of the heat sink 15 onto the first support section 211 can be located within this first heat dissipation area. Similarly, the side of the rear shell 23 furthest from the first support section 211 is also the exterior surface, making it impossible to create heat dissipation holes. Therefore, a second heat dissipation area is provided on the front shell 11. This second heat dissipation area is located within the area enclosed by the orthogonal projection of the edge of the first mating part onto the first support section 211, and it includes multiple second heat dissipation holes 114.

[0059] Cold air enters through outlet hole 2331, and hot air exits through outlet hole 2331. For example... Figure 6 As shown, the entry path of cold air is illustrated. The arrows indicate the direction of the cold air inside the display device. The cold air flows from the outlet hole 2331 to the through hole 2112. A portion of the cold air flows along the surface of the first support section 211 towards the circuit board 14 and the heat sink 15. The heat sink 15 conducts the heat generated by the circuit board 14 to the side and then conducts it to the external space through the first heat dissipation hole 2113. At the same time, another portion of the air can flow out from the second heat dissipation hole 114, accelerating the airflow speed inside the front cover 11 and enabling more efficient airflow.

[0060] like Figure 7 As shown, to better guide air from the outlet hole 2331 to the through hole 2112, the support assembly 2 also includes multiple spacer bars 234 and reinforcing ribs 235. The spacer bars 234 are spaced apart along the extension direction of the second support section 212 and are parallel to the edge of the first mating part. The reinforcing ribs 235 are also arranged along the extension direction of the second support section 212 and are connected to the spacer bars 234. A counterweight 24 is connected to the second support section 212. The counterweight 24 is also arranged along the extension direction of the second support section 212, connected to the second support section 212, and in contact with the reinforcing ribs 235. The outlet hole 2331 is located between two counterweights 24. The airflow can be restricted by the counterweights 24, spacer bars 234, or reinforcing ribs 235, allowing air to flow more efficiently within the cavity formed by the rear shell 23 and the bracket 21.

[0061] like Figures 8 to 11 As shown, the display device may further include a flexible circuit board 123, which is bonded to the display panel 124 and bent to the non-display side of the display panel 124. Since the chips on the flexible circuit board 123 generate a lot of heat, a metal connector can be provided on the side of the flexible circuit board 123 away from the chips to reinforce it. This can be achieved by first soldering the flexible circuit board 123 to the heat dissipation pipes using the metal connector, and then bonding the metal connector to the flexible circuit board 123 using a reinforcement process.

[0062] like Figures 8 to 11 As shown, the heat dissipation system includes a first heat dissipation pipe 191 and a second heat dissipation pipe 192. One end of the first heat dissipation pipe 191 is connected to the side of the flexible circuit board 123 away from the chip, and extends from the side of the flexible circuit board 123 away from the chip to the side of the heat sink 15 near the first adapter plate. The second heat dissipation pipe 192 extends along the side of the heat sink 15 near the first adapter plate and bends to the side of the circuit board 14 away from the first adapter plate. The orthographic projection of the second heat dissipation pipe 191 on the first support section is located within the first heat dissipation area. Heat can be conducted from the heat sink 15 and the flexible circuit board 123 to the first heat dissipation hole 2113.

[0063] like Figure 8 and Figure 9 As shown, there is a certain gap in the height direction between the heat sink 15 and the flexible circuit board 123. The first heat sink 191 is attached to the side of the flexible circuit board 123 away from the chip. The second heat sink 192 is partially disposed between the first heat sink 191 and the heat sink 15, and overlaps with the first heat sink 191. The second heat sink 192 extends along the surface of the first adapter plate and bends to the side of the circuit board 14 away from the first adapter plate. The first heat sink 191 and the second heat sink 192 form a whole. It only needs to be connected to the heat sink 15 once to conduct the heat of the flexible circuit board 123 and the heat sink 15 to the first heat dissipation hole 2113 at the same time, which is low cost.

[0064] Because there is a certain distance between the first heat sink 191 and the edge of the heat sink 15, it needs to extend towards the heat sink 15. The first heat sink 191 may include a first extension segment 1911, a second extension segment 1912, and a third extension segment 1913 connected in sequence. The first extension segment 1911 extends along a first direction and is spaced apart from the edge of the display panel 124. The second extension segment 1912 extends along a second direction, and part of its orthographic projection on the circuit board 14 is located within the orthographic projection of the heat sink 15 on the circuit board 14. The third extension segment 1913 extends along the first direction, and its orthographic projection on the circuit board 14 is located within the orthographic projection of the heat sink 15 on the circuit board 14.

[0065] like Figure 10 As shown, the display device includes a first heat sink 191 and a second heat sink 192. The first heat sink 191 is attached to the side of the flexible circuit board 123 away from the chip. The second heat sink 192 is parallel to the first heat sink 191 and extends along the surface of the first adapter plate and bends to the side of the circuit board 14 away from the first adapter plate. The first heat sink 191 and the second heat sink 192 do not overlap, which increases the contact area between the heat sink and the heat sink 15. The heat from the flexible circuit board 123 is first conducted to the heat sink 15, and then from the heat sink 15 to the first heat dissipation hole 2113, resulting in higher heat dissipation efficiency.

[0066] It should be noted that, in addition to the components mentioned above, the display device may also include other necessary components and elements, such as power cords, etc. Those skilled in the art can make corresponding additions according to the specific usage requirements of the display device, which will not be elaborated here.

[0067] The display device can be a traditional electronic device, such as a mobile phone, computer, television, projector, or camcorder. When the display module includes lenses, the display device can also be an emerging type of display device, such as a VR display device. During display, the second support section of the stand is placed on the ground, so that the display panel on the front housing assembly is roughly level with the eyes, and the display panel displays the image. When the display device is a VR display device, the displayed image is magnified and projected onto the eyes through lenses.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
