[0085] 1 to 39 , this embodiment provides a wall-mounted display device, including a front housing assembly 1 , a rear housing assembly 2 , and a wall-mounted assembly 3 ;

[0086] The front housing assembly 1 is used to fix the display module 112, and the front housing assembly 1 is pivotally connected to the rear housing assembly 2 via a rotating structure;

[0087] The wall-mounted component 3 is arranged on a side of the rear housing component 2 facing away from the front housing component 1;

[0088] The rotating structure includes a rotating part 200 and a support rod 249. The rotating part 300 is connected between the front shell component 1 and the rear shell component 2, so that the front shell component 1 can be rotated and flipped open relative to the rear shell component 2. The support rod 249 is arranged between the front shell component 1 and the rear shell component 2, and is used to enable the front shell component 1 and the rear shell component 2 to switch between an open state and a buckled state.

[0089] In this embodiment, the front housing assembly 1 and the rear housing assembly 2 are pivotally connected via a rotating structure, so that the front housing assembly 1 can be opened or closed relative to the rear housing assembly 2, thereby facilitating maintenance of the wall-mounted display device.

[0090] In an exemplary embodiment, the rotating structure includes a rotating part 200 and a support rod 249, the rotating part 200 includes a first sub-rotating part 105 arranged at the top of the front shell component 1 and a second sub-rotating part 106 located at the top of the rear shell component 2, the front shell component 1 includes a first side and a second side adjacent to its top, the rear shell component 2 includes a third side and a fourth side adjacent to its top, the support rod 249 is arranged between the first side and the third side, and the support rod 249 is arranged between the second side and the fourth side.

[0091] Figures 33-35 are schematic diagrams of the front housing assembly 1 being flipped open relative to the rear housing assembly 2, and Figure 36 is a schematic diagram of the front housing assembly 1 being locked with the rear housing assembly 2. The provision of the support rod 249 facilitates the rotational flipping of the front housing assembly 1 relative to the rear housing assembly 2. After the front housing assembly 1 is flipped open, the support rod 249 can support the front housing assembly 1, thereby keeping the front housing assembly 1 and the rear housing assembly 2 in the flipped open position for easy maintenance.

[0092] Exemplarily, the support rod 249 is a hydraulic support rod, but the present invention is not limited thereto.

[0093] The specific structural form of the rotating component 200 can be various. For example, the first sub-rotating part 105 can include a first rotating shaft, the second sub-rotating part 106 can include a second rotating shaft, and the first rotating shaft and the second rotating shaft are connected by a transmission member to form a double-rotating shaft structure. For example, the rotating component is a hinge-type structure, the first sub-rotating part 105 includes a first hinge piece and a first pivot hole, the second sub-rotating part 106 includes a second hinge piece and a second pivot hole, and the first pivot hole and the second pivot hole cooperate to allow the rotating shaft to pass through. For another example, referring to Figures 41 and 42, the first sub-rotating part 105 includes a first fixing part and a plug-in hole provided at one end of the first fixing part, and the second sub-rotating part 106 includes a second fixing part and a pivot shaft provided at one end of the second fixing part, and the pivot shaft can be plugged into the plug-in hole.

[0094] Exemplarily, the wall-mounted display device also includes a safety lock 2450, which includes a first part 245 located at the bottom of the front shell assembly 1 and a second part 244 located at the bottom of the rear shell assembly 2. The first part 245 and the second part 244 are locked together by an unlocking piece to lock the front shell assembly 1 and the rear shell assembly 2 together.

[0095] It should be noted that the specific structure of the safety lock can be various. For example, the first part 245 is the safety lock body, and the second part 244 is the safety lock base.

[0096] FIG43 is a schematic diagram showing the locked state of the safety lock. The safety lock may be a commonly used safety lock for outdoor advertising boxes, which will not be described in detail here.

[0097] The setting of the safety lock 2450 prevents the box from being opened arbitrarily by humans (ie, separating the front shell component 1 and the rear shell component 2), which may cause hidden dangers. The safety lock can only be opened with an unlocking piece during maintenance or repair by professionals.

[0098] Exemplarily, the unlocking member may be a key.

[0099] Referring to Figures 2 to 5, in an exemplary embodiment, the front shell assembly 1 includes a first frame body, the first frame body includes an outer frame 104 and a middle frame 103, the middle frame 103 is formed by a plurality of first frame frames with L-shaped cross-sections, the outer frame 104 is arranged outside the middle frame 103, and the inner side wall of the outer frame 104 is connected to the first side wall of the first frame, and one end of the support rod 249 is fixed to the middle frame 103.

[0100] The outer frame 104 and the middle frame 103 are both annular structures. It should be noted that the width of the first side wall is smaller than the width of the side wall of the outer frame 104 to provide installation space for assembling the display module 112 and the glass cover 101.

[0101] One end of the support rod 249 is fixed to the first side wall of the middle frame 103 to avoid affecting the installation of other components such as the display module 112 .

[0102] 2 to 11 , in an exemplary embodiment, the first bottom wall of the middle frame 103 includes a first connecting surface and a second connecting surface disposed opposite each other. The first connecting surface is provided with a support member 100 for supporting and fixing the display module 112. The second connecting surface is fixedly connected to the glass cover plate 101. The light-emitting surface of the display module 112 is disposed toward the glass cover plate 101.

[0103] A first vent hole 1041 is provided on a second side wall of the outer frame 104, refer to FIG4 and FIG11 ;

[0104] The support member 100 is respectively provided with a second air vent 10011 at both opposite ends, and one of the second air vents 10011 is provided corresponding to the first air vent 1041. The first air vent 1041 and the second air vent 10011 cooperate with each other so that the air flow entering from the first air vent 1041 passes through the light-emitting side of the display module 112 and enters the rear shell assembly 2, and is discharged through the exhaust port of the rear shell assembly 2 (a fan is provided at the exhaust port to facilitate the gas to flow along a preset path, and the setting of the fan will be specifically introduced later).

[0105] The setting of the support member 100 creates a gap between the display module 112 and the glass cover plate 101. The setting of the first vent 1041 and the second vent 10011 allows the gap to communicate with the outside world, allowing external air to pass through the light-emitting side of the display module 112 and finally be discharged through the exhaust port of the rear shell assembly 2 to achieve heat dissipation of the display module 112.

[0106] Exemplarily, when the wall-mounted display device is in a wall-mounted state, the first ventilation hole 1041 is arranged on the second side wall at the bottom of the outer frame 104, one second ventilation hole 10011 is located at the bottom end of the support member 100, and one second ventilation hole 10011 is located at the top end of the support member 100.

[0107] Exemplarily, the support member 100 is formed by enclosing a plurality of second frames with a U-shaped cross-section (the support member 100 in FIG9 includes four second frames, namely a bottom frame 1001, a top frame 1002, a first side frame 1003, and a second side frame 1004). The second frame includes a third side wall and a fourth side wall that are oppositely arranged, and a second bottom wall located between the third side wall 10001 and the fourth side wall 10002. The third side wall 10001 is connected to the first bottom wall of the middle frame 103, and the fourth side wall 10002 is used to connect to the display module 112 on a side away from the third side wall 10001, refer to FIG11 ;

[0108] The second ventilation holes 10011 are provided on the second bottom walls of the second frames located at opposite ends of the support member 100 (refer to the bottom frame 1001 and the top frame 1002 in FIG. 9 ), refer to FIG. 7 and FIG. 8 .

[0109] The second frame is a strip-shaped structure as a whole, the longitudinal section of the second frame is a U-shaped structure, the opening of the second frame is set toward the outside, and avoidance gaps are set on the third side wall 10001 and the fourth side wall 10002 of the second frame to avoid other structures.

[0110] Illustratively, a plurality of second ventilation holes 10011 are spaced apart on the second bottom wall along the length direction of the corresponding second frame.

[0111] Illustratively, the two second ventilation holes 10011 include one second ventilation hole 10011 disposed close to the first ventilation hole 1041 , and the second ventilation hole 10011 is staggered with the first ventilation hole 1041 to achieve a waterproof effect.

[0112] Exemplarily, the second ventilation holes 10011 located on the two opposite second frames of the support member 100 are arranged in a one-to-one correspondence, that is, the orthographic projection of the second ventilation hole 10011 on one second frame on the other second frame coincides with the second ventilation hole 10011 on the other second frame, so as to facilitate the airflow entering from one second ventilation hole 10011 to pass through the light-emitting side of the display module 112 and then smoothly enter the rear shell assembly 2 from the other second ventilation hole 10011.

[0113] Exemplarily, the glass cover plate 101 is fixed to the middle frame 103 by means of waterproof engineering adhesive, thereby improving the waterproof effect of the wall-mounted display device.

[0114] Referring to Figures 2 and 9, exemplarily, a light sensor 102 is provided on the first connecting surface of the first bottom wall of the middle frame 103, and the light sensor 102 is used to sense the intensity of external light to adjust the display state of the display module 112. A first photosensitive hole is provided on the first bottom wall to avoid the photosensitive area of ​​the light sensor 102, and a second photosensitive hole 10012 corresponding to the first photosensitive hole is provided on the edge of the glass cover 101 to allow external light to enter the light sensor 102.

[0115] The provision of the light sensor 102 enables the wall-mounted display device to automatically sleep when no one is around late at night, thereby reducing power consumption and avoiding problems such as component loss caused by prolonged lighting.

[0116] Referring to Figures 12-15, exemplarily, the front shell assembly 1 also includes a first fixing beam 113 fixed to the middle frame 103 by a fixing member. After the display module 112 is installed on the front shell assembly 1, the first fixing beam 113 is located on the backlight side of the display module 112 to lock the display module 112 on the front shell assembly 1.

[0117] The provision of the first fixing beam 113 enhances the connection stability of the display module 112. The number of the first fixing beams 113 can be set according to actual needs. When the wall-mounted display device is wall-mounted, the first fixing beam 113 is horizontally provided. In the horizontal direction, first fixing members 111 are provided on the first side frames on opposite sides of the middle frame 103. The opposite ends of the first fixing beam 113 are respectively fixed to the corresponding first fixing seats 111.

[0118] The backlight side of the display module is provided with a module control board 1121 for controlling the display drive of the display module. The backlight side of the display module also includes a TCON board 1122 for controlling the light emission of the backlight structure in the display module.

[0120] The provision of the reinforcement enhances the strength of the second frame 201 . The reinforcement may have various specific structural shapes, for example, the reinforcement may be L-shaped or X-shaped.

[0121] The number and setting positions of the reinforcement members can also be various. For example, a plurality of the reinforcement members in a cross shape are arranged at intervals on each of the first side panels, and when the wall-mounted display device is in a wall-mounted state, the reinforcement beam 2013 in a strip-shaped structure extending in the horizontal direction is arranged between the two opposite first side panels.

[0122] In some embodiments, an X-shaped reinforcement 2011 is provided on the first side panel, and a horizontally arranged strip reinforcement beam is provided between the two oppositely arranged first side panels, the opposite ends of the strip reinforcement beam are fixed to the corresponding X-shaped reinforcement 2011, and an L-shaped reinforcement 2012 is also provided on the first side panel.

[0123] Exemplarily, an I-shaped reinforcement is provided on the first side panel, and two outer flanges 20011 extending in opposite directions from each other of the I-shaped reinforcement are fixedly connected to the first side panel, refer to FIG. 40 .

[0124] 18-21 , exemplarily, a second fixing beam 202 is provided on the inner side surface of the first base plate, the wall-mounted component 3 is fixed on the outer side surface of the first base plate, and the wall-mounted component 3, the first base plate and the second fixing beam 202 are fixed together by bolts.

The second fixing beam 202, the rear housing assembly 2, and the wall-mounting assembly 3 form a sandwich structure, which enhances the wall-mounting strength of the wall-mounting assembly 3. The second fixing beam 202 extends in the vertical direction, and cooperates with the horizontally arranged first fixing beam 113 to further enhance the strength of the rear housing assembly 2.

[0126] Exemplarily, an air inlet 221 and an air outlet 222 are respectively provided at opposite ends of the first base plate, and a first fan assembly 204 is provided on the first base plate, and the orthographic projection of the first fan assembly 204 on the first base plate is located on one side of the air outlet 222.

[0127] The orthographic projection of the first fan assembly 204 on the first base plate is located on one side of the air outlet 222, that is, the first fan assembly 204 and the air outlet 222 are staggered, which can serve as a waterproof channel for the air outlet 222 to prevent rainwater from splashing directly into it.

[0128] For example, when the wall-mounted display device is in a wall-mounted state, the air inlet 221 is located near the bottom of the first base plate, and the air outlet 222 is located near the top of the first base plate. The first fan assembly 204 is provided to dissipate heat. A schematic diagram of the airflow from the air inlet 221 is shown in FIG23 .

[0129] Exemplarily, the first fan assembly 204 includes a first fan fixing base 218 , a first fan 219 fixed at a fan port 217 of the first fan fixing base 218 , and a first protective cover 220 disposed on a side of the first fan 219 away from the first fan fixing base 218 .

[0130] The orthographic projection of the fan port 217 on the first bottom plate is located on one side of the air outlet 222 , that is, the first fan 219 and the air outlet 222 are staggered to achieve a waterproof effect.

[0131] The first protective cover 220 is provided to prevent accidental contact with the fan or circuit during maintenance, thereby preventing malfunction.

[0132] When the wall-mounted display device is in a wall-mounted state, a plurality of the first fans 219 may be arranged along the horizontal direction to improve the heat dissipation effect.

[0134] When the wall-mounted display device is in a wall-mounted state, the first direction is a horizontal direction, and the setting of the wind baffle 234 separates the first fan 219 into two, one part is used for heat dissipation between the display module 112 and the glass cover plate 101, and the other part is used for heat dissipation of components such as the back board and power supply. The flow direction diagram of the airflow used for heat dissipation between the display module 112 and the glass cover plate 101 is shown in Figure 25. The airflow enters from the first vent on the outer frame 104, then enters between the display module and the glass cover plate through the second vent on the support 100, and then is discharged from the air outlet 222 of the rear shell assembly.

[0135] 22 and 37 , illustratively, a filter assembly 203 is further provided on the first bottom plate, and the inlet of the filter assembly 203 is staggered with the air inlet 221 .

[0136] When the wall-mounted display device is used for a wall-mounted digital signage, it is generally used for outdoor wall-mounting. The inlet of the filter component 203 is staggered with the air inlet 221, and the first fan component 204 is staggered with the air outlet 222, both of which prevent rainwater from splashing into the interior. This design not only ensures the heat dissipation of the entire machine, but also ensures that rainwater cannot enter the chassis.

[0137] Illustratively, the filter assembly 203 includes an air filter storage bin 233 , an air filter dust screen 232 , an air filter 231 and an air filter protection plate 230 , which are sequentially arranged in a direction away from the air inlet 221 .

[0138] The function of the air filter 231 is to effectively filter dust and impurities in the air, making the air entering the wall-mounted display device cleaner and preventing impurities in the air from corroding the circuit board 246 and internal electrical equipment. The air filter dust net 232 can filter out some larger particles of air impurities, and the air filter protective plate plays a protective role on the air filter and other structures.

[0139] Exemplarily, referring to Figure 37, the air filter dust net 32 ​​includes a support outer frame 2322, a support inner frame 2321 and a dust net 2323, the dust net 2323 is fixed on the support inner frame 2321, and the support outer frame 2322 is surrounded by the support inner frame 3221 to fix the air filter dust net as a whole on the air filter storage bin 233.

[0140] 22 and 38 , illustratively, a second fan assembly 205 is further provided on the first bottom plate. The second fan assembly 205 is provided on a side of the filter assembly 203 close to the air outlet 222 .

[0149] An infrared sensor 247 is provided on the first bottom plate, and the infrared remote controller is provided on a side of the filter component 203 away from the air outlet 222. The infrared sensor 247 is used to sense the remote control infrared light incident from the through hole so as to perform corresponding remote control operations through the remote controller.

[0150] When the wall-mounted display device is used for a wall-mounted digital signage, the hanging position is relatively high. In order to facilitate operation, the photosensitive area of ​​the infrared sensor 247 used to cooperate with the remote control is set downward, that is, the through hole for exposing the infrared sensor 247 is set at the bottom of the second frame 201.

[0151] The infrared sensor 247 is arranged on a circuit board 246, and the circuit board 246 is fixed on the first bottom plate of the second frame 201 through a fixing bracket 248. An opening is opened on the fixing bracket 248 to expose the infrared sensor 247, and the orthographic projection of the opening on the first sub-side panel is located in the through hole on the first sub-side panel to ensure that the infrared sensor 247 can receive the infrared light emitted by the remote control.

[0152] Referring to Figures 26 to 29, each of the first side panels is folded inward multiple times and extends away from the first bottom panel to form a sealing plate 2011 parallel to the first side panel. The rear shell assembly 2 also includes a sealing ring 239, and one side of the sealing ring 239 has an insertion port for inserting the sealing plate 2011.

[0153] After the front shell assembly 1 and the rear shell assembly 2 are assembled, especially when the front shell assembly 1 and the rear shell assembly 2 are in a locked state, the backlight side of the display module 112 is sealed and crimped with the sealing ring 239 to achieve a sealed and waterproof effect, thereby solving the waterproof problem in outdoor installation scenarios.

[0154] 30 and 31 , illustratively, a hanging ring 240 is provided on the top of the second frame body 201 , or hanging rings 240 are provided on the two first side panels of the second frame body 201 adjacent to the top thereof.

[0155] Generally, the whole wall-mounted display device is heavy, exceeding 150kg, and the installation scenario is hoisting. Adding the lifting ring 240 facilitates hoisting and achieves the purpose of convenient installation, solving the problem of large-sized products being difficult to install on the wall.
