Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a display device. Background Art

[0002] Display devices on the market generally consist of three main parts: a front cover module, a display module and a rear cover module. These modules are connected by bolts to ensure the stability of the structure.

[0003] However, existing display devices have deficiencies in terms of maintenance and repair. For example, when repairing and replacing electronic components inside a display device, the operator needs to remove the entire device from its original fixed position and then open the rear cover module to replace the internal components. This operation method is not only time-consuming and labor-intensive, but also, since the display device is generally heavy, there are certain safety risks when removing the entire device.

[0004] Therefore, how to improve the connection method of each module inside the display device has become a problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the present application is to provide a display device that can quickly and conveniently inspect and repair various modules inside the display device.

[0006] To achieve the above-mentioned purpose, on one hand, the present application provides a display device, which comprises at least a front cover module, a display module and a rear cover module, wherein a front cover connector is provided at the top of the rear cover module, and the front cover module is pivotally connected to the rear cover module via the front cover connector; a screen connector is provided at the top of the rear cover module, and the display module is pivotally connected to the rear cover module via the screen connector; the display module is provided between the front cover module and the rear cover module, the maximum flip angle of the display module is smaller than the maximum flip angle of the front cover module, and the rotation axis of the display module is parallel to the rotation axis of the front cover module.

[0007] It can be seen from this that the technical solution provided by the present application, the display device is composed of a front cover module, a display module and a rear cover module. The top of the rear cover module is designed with a front cover connector and a screen connector to connect the front cover module and the display module respectively, and the front cover connector and the screen connector are both rotatable parts. In this way, the front cover module and the display module can be turned outward independently of the rear cover module with the top of the rear cover module as the rotation reference point. Since the display module and the front cover module are located on the same side of the rear cover module, and the display module is arranged between the front cover module and the rear cover module. Therefore, when the operator needs to repair or replace electronic components, it is not necessary to remove the entire machine from the original fixed position. It is only necessary to open the front cover module separately according to actual needs, or open the front cover module and the display module in the same direction at the same time, so that various electronic components inside the display device can be exposed, so as to facilitate the operator to repair or replace various electronic components. At the same time, the flip angle of the display module is smaller than that of the front cover module, which can avoid the front cover module from obstructing the display module during the flipping process. The flip connection solution provided by the present application not only simplifies the maintenance process and reduces the equipment maintenance time, but also reduces the risk of damage to the equipment caused by frequent disassembly and assembly.

[0020] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in the present application to represent spatial relative positions are used to describe the relationship between a unit or feature as shown in the accompanying drawings relative to another unit or feature for the purpose of convenience of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptors used herein are interpreted accordingly.

[0021] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] Display devices on the market generally consist of three main parts: front cover module, display module and back cover module. These modules are usually connected mechanically by bolts to ensure the structural stability of the entire device. The front cover module is located at the front and is designed to provide physical protection for the display module, which is the core part of information display. The back cover module is generally fixed to the wall, column or other supporting structure to provide support and fixation for the entire display device.

[0023] However, existing display devices have some deficiencies in equipment maintenance and repair. For example, when it is necessary to repair or replace the electronic components inside the display device, the operator must remove the entire display device from its original fixed position and then open the back cover module to repair or replace the internal components. This operation method is not only time-consuming and labor-intensive, but also may pose safety risks during disassembly and transportation because the display device is usually heavy. For another example, if the operator only needs to repair the display module, since the front cover module cannot be opened separately, the operator still needs to dismantle the machine as a whole before repairing the display module, and the repair procedure is cumbersome.

[0024] Therefore, how to improve the connection method of each module inside the display device so as to quickly and conveniently inspect and repair each module inside the display device has become a problem that needs to be solved urgently in the art.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0026] The present application provides a display device, and the specific type of the display device can be an electronic device such as an advertising machine, a conference tablet, an interactive tablet, etc.

[0027] Please also see Figures 1 to 11As shown, in an achievable embodiment, the display device at least includes a front cover module 1, a display module 2 and a rear cover module 3. A front cover connector 31 is provided on the top of the rear cover module 3, and the front cover connector 31 is a rotatable component, and its specific structure can refer to components such as hinges and hinges. The movable end of the front cover connector 31 is connected to the front cover module 1, and the fixed end of the front cover connector 31 is fixedly connected to the shell of the rear cover module 3, so that the front cover module 1 is pivotally connected to the rear cover module 3 through the front cover connector 31. In other words, after the front cover module 1 is connected to the rear cover module 3 through the front cover connector 31, the front cover module 1 can rotate around the rotation axis of the front cover connector 31, and the rotation axis of the front cover module 1 is the rotation axis of the front cover connector 31. It should be noted that the front cover connector 31 can rotate around a rotation center or rotation axis, and the straight line where the rotation center or rotation axis is located is the rotation axis of the front cover connector 31. The rotation axis of the front cover connector 31 can be a physical axis (such as a pivot in a hinge) or a rotation geometric center in the design of a rotating component. In this embodiment, after the front cover module 1 and the rear cover module 3 are attached, the front cover module 1 can be turned over in a direction away from the rear cover module 3 using the front cover connector 31.

[0028] Furthermore, a screen connector 32 is also provided on the top of the rear cover module 3. The screen connector 32 is also a rotatable component, and its specific structure can refer to components such as hinges and hinges. The movable end of the screen connector 32 is connected to the display module 2, and the fixed end of the screen connector 32 is fixedly connected to the shell of the rear cover module 3, so that the display module 2 is pivotally connected to the rear cover module 3 through the screen connector 32. In other words, after the display module 2 is connected to the rear cover module 3 through the screen connector 32, the display module 2 can rotate around the rotation axis of the screen connector 32, and the rotation axis of the display module 2 is the rotation axis of the screen connector 32. It should be pointed out that the screen connector 32 can rotate around a rotation center or rotation axis, and the straight line where the rotation center or rotation axis is located is the rotation axis of the screen connector 32. The rotation axis of the screen connector 32 can be a physical axis (such as a pivot in a hinge) or a rotation geometric center in the design of a rotating component. In this embodiment, after the display module 2 is attached to the rear cover module 3 , the display module 2 can be flipped in a direction away from the rear cover module 3 by using the screen connector 32 .

[0029] In practical applications, the rear cover module 3 can be fixed to a wall, a cylinder or other supporting structures by means of bolts or other connectors. The display module 2 and the front cover module 1 are located on the same side of the rear cover module 3, and the display module 2 is arranged between the front cover module 1 and the rear cover module 3. When the operator inspects the internal components of the display device, he can first open the front cover module 1 to flip the front cover module 1 away from the rear cover module 3, and then open the display module 2 to flip the display module 2 away from the rear cover module 3. In this way, various components inside the display device can be exposed to the operator, so that the operator can inspect or replace them conveniently.

[0030] Since the front cover module 1 and the display module 2 flip outward in the same direction, in order to avoid interference between the two during the flipping process, in this embodiment, the maximum flipping angle of the display module 2 is designed to be smaller than the maximum flipping angle of the front cover module 1, thereby ensuring that during the flipping process, the front cover module 1 will not hinder the movement path of the display module 2. In other words, when the front cover module 1 is fully opened, the display module 2 can be freely flipped to the extreme position allowed by its design without interfering with the front cover module 1.

[0031] It should be noted that although both the front cover module 1 and the display module 2 can be turned outward, the operator can only turn over the front cover module 1 according to actual needs. For example, if the operator only needs to replace the filter cotton or wipe the display panel in the display module 2, the operator can only turn over the front cover module 1 outward without turning over the display module 2.

[0032] Furthermore, in order to minimize the space occupied by the flipping action, the rotation axis of the display module 2 is constructed to be parallel to the rotation axis of the front cover module 1. At the same time, the parallel rotation axes also help to maintain the coordination of the flipping action of the front cover module 1 and the display module 2, making the operation of the entire display device smoother and more consistent.

[0033] When the front cover module 1 is turned outward, the operator can place a supporting element (such as a bar, a block, etc.) between the front cover module 1 and the rear cover module 3 to help the front cover module 1 remain at a specific angle. Correspondingly, when the display module 2 is turned outward, the operator can also place a supporting element between the display module 2 and the rear cover module 3 to help the display module 2 remain at a specific angle.

[0034] In an achievable implementation, a front cover pneumatic rod 11 is provided between the front cover module 1 and the rear cover module 3. The front cover pneumatic rod 11 can serve as a supporting element to help the front cover module 1 remain at a specific angle, thereby reducing the risk of the front cover module 1 falling due to gravity. At the same time, the front cover pneumatic rod 11 can also reduce the force required by the operator when opening or closing the front cover module 1, and complete the flipping action with the assistance of gas pressure, thereby improving the user experience.

[0035] To ensure that the front cover module 1 can be turned over normally, one end of the front cover pneumatic rod 11 is rotatably connected to the front cover module 1, and the other end of the front cover pneumatic rod 11 is rotatably connected to the rear cover module 3. Specifically, the front cover module 1 is provided with a first support member 12 on one side facing the rear cover module 3, and the rear cover module 3 is provided with a second support member 33 on one side facing the front cover module 1. Both the first support member 12 and the second support member 33 adopt a pivot structure, and both ends of the front cover pneumatic rod 11 are respectively connected to the above-mentioned pivot structure to achieve a rotatable connection.

[0036] like Figure 3 As shown, in order to effectively utilize the space between the front cover module 1 and the rear cover module 3 and provide better support stability for the front cover module 1, the front cover pneumatic rod 11 can be placed between the front cover module 1 and the rear cover module 3 at a certain angle. For example, if the display device is fixed on a vertical wall as a reference, the front cover pneumatic rod 11 is placed between the front cover module 1 and the rear cover module 3 at a certain angle. It can be understood that: when the front cover module 1 and the rear cover module 3 are attached together, there is a certain angle between the front cover pneumatic rod 11 and the front cover module 1 and the rear cover module 3, and the front cover pneumatic rod 11 is slightly inclined relative to the ground.

[0037] In this embodiment, the front cover pneumatic rod 11 can adjust the flip angle of the front cover module 1 by changing the distance between the front cover module 1 and the rear cover module 3. Specifically, when subjected to external force, the length of the front cover pneumatic rod 11 can change, thereby pushing or pulling the front cover module 1 to move. In this way, the distance between the front cover module 1 and the rear cover module 3 will change accordingly. Since the front cover module 1 is pivotally connected to the rear cover module 3 through the front cover connecting member 31, the front cover module 1 will rotate around the rotation axis of the front cover connecting member 31, thereby changing the flip angle of the front cover module 1 relative to the rear cover module 3.

[0038] In an achievable implementation, a screen pneumatic rod 13 is provided between the display module 2 and the rear cover module 3. The screen pneumatic rod 13 can serve as a supporting element to help the display module 2 remain at a specific angle, thereby reducing the risk of the display module 2 falling due to gravity. At the same time, the screen pneumatic rod 13 can also reduce the force required by the operator to open or close the display module 2, and complete the flipping action through gas pressure to improve the user experience.

[0039] To ensure that the display module 2 can be turned over normally, one end of the screen pneumatic rod 13 is rotatably connected to the display module 2, and the other end of the screen pneumatic rod 13 is rotatably connected to the rear cover module 3. Specifically, a third support member 14 is provided on the side of the display module 2 facing the rear cover module 3, and a fourth support member 34 is provided on the side of the rear cover module 3 facing the display module 2. Both the third support member 14 and the fourth support member 34 adopt a pivot structure, and both ends of the screen pneumatic rod 13 are respectively connected to the above-mentioned pivot structure to achieve a rotatable connection.

[0040] like Figure 3 As shown, in order to effectively utilize the space between the display module 2 and the back cover module 3 and provide better support stability for the display module 2, the screen pneumatic rod 13 can be placed between the display module 2 and the back cover module 3 at a certain angle. For example, if the display device is fixed on a vertical wall as a reference, the screen pneumatic rod 13 is placed between the display module 2 and the back cover module 3 at a certain angle. It can be understood that when the display module 2 and the back cover module 3 are attached together, there is a certain angle between the screen pneumatic rod 13 and the display module 2 and the back cover module 3, and the screen pneumatic rod 13 is slightly inclined relative to the ground.

[0041] In this embodiment, the screen pneumatic rod 13 can adjust the flip angle of the display module 2 by changing the distance between the display module 2 and the rear cover module 3. Specifically, when subjected to external force, the length of the screen pneumatic rod 13 can change, thereby pushing or pulling the display module 2 to move. In this way, the distance between the display module 2 and the rear cover module 3 will change accordingly. Since the display module 2 is pivotally connected to the rear cover module 3 through the screen connector 32, the display module 2 will rotate around the rotation axis of the screen connector 32, thereby changing the flip angle of the display module 2 relative to the rear cover module 3.

[0042] In a feasible implementation, the front cover module 1 can provide necessary protection for the display module 2 and the rear cover module 3, while ensuring long-term stable operation of the device in an outdoor environment. The front cover module 1 includes a window protective cover 15 and a reinforcement frame 16, wherein the reinforcement frame 16 is arranged around the periphery of the window protective cover 15. Specifically, the reinforcement frame 16 surrounds and is fixed to the back of the window protective cover 15 to form a support for the window protective cover 15, thereby strengthening the structural strength of the window protective cover 15 and preventing the window protective cover 15 from deforming. In actual applications, the main body of the window protective cover 15 can be made of metal materials such as galvanized sheet and aluminum alloy, and covered with high-transmittance tempered glass, acrylic plate and other materials to ensure that the content displayed by the display module 2 can be clearly displayed in front of the audience. The reinforcement frame 16 can be made of metal material, and the cross-sectional shape of the reinforcement frame 16 can be constructed to be similar to the cross-sectional shape of the window protective cover 15, and the size of the reinforcement frame 16 is slightly smaller than the window protective cover 15, and then the reinforcement frame 16 is embedded in the window protective cover 15 as a whole to enhance the structural strength of the window protective cover 15. It should be noted that the reinforcement frame 16 and the window protective cover 15 can be connected as a whole by bolts or rivets to prevent the reinforcement frame 16 from falling off the window protective cover 15.

[0043] A sealing groove 161 is formed at the top of the reinforcement frame 16, and a docking member 162 is arranged in the sealing groove 161. The docking member 162 can be a plate-shaped structure and made of metal material. The docking member 162 can be fixed to a side groove wall of the sealing groove 161 close to the window protection cover 15 by riveting or welding. The docking member 162 is used to connect with the front cover connector 31, so that the front cover module 1 can be rotatably connected to the rear cover module 3.

[0044] It should be noted that the sealing groove 161 can be formed on all four edges of the strengthening frame 16, or only on the top of the strengthening frame 16, and the present application does not limit this. The sealing groove 161 can cooperate with the structure on the rear cover module 3, so that after the front cover module 1 and the rear cover module 3 are attached together, the gap between the front cover module 1 and the rear cover module 3 is sealed, and this will be described in detail later.

[0045] In order to improve the sealing between the front cover module 1 and the rear cover module 3, in a feasible embodiment, a snap-in groove 35 is provided on the top of the rear cover module 3. The cross-sectional shape of the snap-in groove 35 is adapted to the cross-sectional shape of the sealing groove 161. When the front cover module 1 and the rear cover module 3 are attached together, the snap-in groove 35 and the sealing groove 161 can be attached to each other, thereby forming a sealing structure such as a circular shape or a labyrinth shape. In order to further improve the sealing between the front cover module 1 and the rear cover module 3, the front cover connector 31 can be provided in the above-mentioned snap-in groove 35, and part of the structure of the front cover connector 31 is exposed from the snap-in groove 35, so as to extend into the sealing groove 161 and connect with the docking member 162. After the front cover module 1 and the rear cover module 3 are attached together, the front cover connector 31 and the docking member 162 are both located in the above-mentioned sealing structure. With the cooperation of the snap-in groove 35 and the sealing groove 161, the gap between the front cover module 1 and the rear cover module 3 can be sealed to prevent dust, rainwater and other debris from entering the interior of the display device, and the front cover connector 31 and the docking component 162 can be closed and protected to improve the reliability and durability of the front cover connector 31 and the docking component 162.

[0046] Optionally, a sealing strip 351 is provided on the outer surface of the clamping groove 35, and when the front cover module 1 and the rear cover module 3 are attached together, the sealing strip 351 can be sealed with the sealing groove 161. For example, the sealing strip 351 can be clamped on the groove wall of the clamping groove 35, and when the front cover module 1 and the rear cover module 3 are attached together, the sealing strip 351 can abut against a side of the sealing groove 161 close to the window protection cover 15 (i.e., the groove wall where the docking member 162 is located), thereby further improving the sealing performance of the above-mentioned sealing structure.

[0047] In an achievable embodiment, the front cover connector 31 includes a rotating shaft 311, a fixed hinge portion 312 and a movable hinge portion 313. The fixed hinge portion 312 can be fixedly connected to the clamping groove 35 by bolts or rivets, and shaft holes are provided on the fixed hinge portion 312 and the movable hinge portion 313. The rotating shaft 311 is inserted into the shaft holes of the fixed hinge portion 312 and the shaft holes of the movable hinge portion 313 at the same time. The rotating shaft 311, the fixed hinge portion 312 and the movable hinge portion 313 together constitute a hinge structure, so that the movable hinge portion 313 is rotatably connected to the fixed hinge portion 312 with the center line of the rotating shaft 311 as the rotation axis.

[0048] The movable hinge part 313 is provided with a hinge hole 3131, and the docking member 162 is provided with a screw hole 1621. The screw hole 1621 cooperates with the hinge hole 3131 on the movable hinge part 313. When the operator needs to install the front cover module 1 on the rear cover module 3, he can first align the screw hole 1621 with the hinge hole 3131 on the movable hinge part 313, and then insert the screw into the screw hole 1621 and the hinge hole 3131 in sequence, so as to fix the front cover module 1 on the movable hinge part 313, so that the front cover module 1 can be fixed on the rear cover module 3. Since the movable hinge part 313 can rotate with the center line of the rotating shaft 311 as the rotating axis, the front cover module 1 can also rotate with the center line of the rotating shaft 311 as the rotating axis, that is, the front cover module 1 can be turned over with the center line of the rotating shaft 311 as the rotating axis.

[0049] It should be noted that the operator may also first connect the movable hinge portion 313 in the front cover connector 31 to the docking member 162, thereby installing the front cover connector 31 on the front cover module 1, and then connect the fixed hinge portion 312 in the front cover connector 31 to the snap-in groove 35. The specific connection method between the front cover connector 31 and the docking member 162 can be set according to the assembly process of the front cover module 1 and the rear cover module 3, and the present application does not limit this.

[0050] Optionally, two or more hinge holes 3131 may be provided on the movable hinge portion 313, and the number of screw holes 1621 corresponds to the number of hinge holes 3131, so that the front cover module 1 can be fixed to the rear cover module 3 using multiple screws to improve the stability of the connection between the front cover module 1 and the rear cover module 3.

[0051] In a feasible implementation, the screen connector 32 includes a connecting rod (not shown), a first hinge portion 321 and a second hinge portion 322. To avoid interference between the screen connector 32 and the front cover connector 31, the first hinge portion 321 can be fixedly connected to the lower part of the clamping groove 35 by bolts or rivets. Axial holes are provided on the first hinge portion 321 and the second hinge portion 322, and the connecting rod is inserted into the axial holes of the first hinge portion 321 and the axial holes of the second hinge portion 322 at the same time. The first hinge portion 321, the second hinge portion 322 and the connecting rod together constitute a hinge structure, so that the second hinge portion 322 is rotatably connected to the first hinge portion 321 with the center line of the connecting rod as the rotation axis.

[0052] The second hinge part 322 is provided with a hinge hole 3221, and the display module 2 is provided with a mounting hole 21 on a side opposite to the rear cover module 3. The mounting hole 21 cooperates with the hinge hole 3221 on the second hinge part 322. When the operator needs to mount the display module 2 on the rear cover module 3, he can first align the mounting hole 21 with the hinge hole 3221 on the second hinge part 322, and then insert the screw into the mounting hole 21 and the hinge hole 3221 in sequence, so as to fix the display module 2 on the second hinge part 322, so that the display module 2 can be fixed on the rear cover module 3. Since the second hinge part 322 can rotate with the center line of the connecting rod as the rotation axis, the display module 2 can also rotate with the center line of the connecting rod as the rotation axis, that is, the display module 2 can be turned over with the center line of the connecting rod as the rotation axis.

[0053] It should be noted that after the connecting rod is inserted into the axial holes of the first hinge part 321 and the second hinge part 322 , the center line of the connecting rod must be parallel to the center line of the shaft 311 to ensure that the rotation axis of the display module 2 is parallel to the rotation axis of the front cover module 1 .

[0054] Optionally, the second hinge portion 322 may be provided with two or more hinge holes 3221, and the number of mounting holes 21 corresponds to the number of hinge holes 3221, so that the display module 2 can be fixed to the back cover module 3 using multiple screws to improve the stability of the connection between the display module 2 and the back cover module 3.

[0055] In actual applications, since the weight of the display module 2 is usually large, when disassembling the display module 2, it is necessary to manually lift the display module 2 so as to remove the bolts in the hinge hole 322, which not only increases the labor intensity of the operator, but also increases the risk of the display module 2 falling. In the process of installing the display module 2, due to the lack of an effective load-bearing and positioning mechanism, multiple operators are required to manually lift the heavy display module 2 and constantly adjust the position of the display module 2 so as to align the installation hole 21 with the hinge hole 3221 on the second hinge portion 322. Generally, three or more operators are required to participate in disassembling or replacing the display module 2, which not only increases the labor cost but also reduces the work efficiency.

[0056] To solve the above problems, in an achievable embodiment, a shaft 36 is provided below the snap-in slot 35, and a hook portion 22 is provided on a side of the display module 2 opposite to the back cover module 3, that is, a hook portion 22 is installed on a side of the display module 2 facing the back cover module 3. The shaft 36 can be a cylindrical structure, a nearly cylindrical structure, or other geometric structures with an arc-shaped surface, and the shaft 36 has a center line, and the center line of the shaft 36 extends along the length direction of the shaft 36. For example, when the shaft 36 is a cylindrical shaft, the center line of the shaft 36 is a straight line where its central symmetry axis is located. When the shaft 36 is a semi-cylindrical shaft, the center line of the shaft 36 is centered along the length direction of the semi-cylinder and is symmetrical with the cross section of the semi-cylinder. Further, after the shaft 36 is installed below the snap-in slot 35, the center line of the shaft 36 coincides with the center line of the connecting rod in the screen connector 32. It should be noted that when understanding the center line of the shaft 36 , the shaft 36 can be regarded as a rotating body, which is formed by a two-dimensional plane figure rotating around a straight line at a certain angle. The straight line can be regarded as the center line of the shaft 36 .

[0057] In this embodiment, the hook portion 22 can be constructed as a thin plate structure, which is fixed to the frame of the display module 2 by riveting or bolting. A groove 221 is provided on the hook portion 22, and the opening direction of the groove 221 faces the ground, and the groove 221 can be engaged with the shaft 36. Further, the cross-sectional shape of the groove 221 matches the cross-sectional shape of the shaft 36. Specifically, the cross-sectional shape of the groove 221 can be an arc or a semicircle, and its radius is greater than the radius of the shaft 36. In this way, after the groove 221 is engaged with the shaft 36, the hook portion 22 can rotate around the center line of the shaft 36.

[0058] During the installation of the display module 2, the operator can first hang the groove 221 on the shaft 36, thereby hanging the display module 2 on the shaft 36, so that the display module 2 can be hung on the back cover module 3. Under the cooperation of the hook part 22 and the shaft 36, the hook part 22 can effectively bear the weight of the display module 2, avoiding the display module 2 from falling during the installation process, thereby protecting the safety of the operator and the equipment during the installation process. Similarly, during the disassembly of the display module 2, since the display module 2 is hung on the shaft 36, the weight of the display module 2 is borne by the shaft 36, so when the operator removes the bolts in the hinge hole 322, there is no need to worry that the display module 2 will suddenly fall from the back cover module 3.

[0059] Since the display module 2 can rotate around the rotation axis of the screen connector 32 (i.e., the center line of the connecting rod in the screen connector 32), the hook portion 22 can rotate around the center line of the shaft 36, and the center line of the shaft 36 coincides with the center line of the connecting rod in the screen connector 32, when the display module 2 rotates around the rotation axis of the screen connector 32, the hook portion 22 can also rotate around the center line of the shaft 36, that is, the hook portion 22 can rotate synchronously with the screen connector 32. The above structure can ensure that the hook portion 22 will not hinder the flipping of the display module 2, and can also use the hook portion 22 to share the weight of the display module 2.

[0060] It should be particularly pointed out that, during the installation of the display module 2, the operator first hangs the groove 221 on the shaft 36, and the weight of the display module 2 is borne by the shaft 36. Therefore, when the display module 2 and the rear cover module 3 are subsequently connected by the screw, the operator does not need to hold the display module 2 all the time, which can significantly reduce the labor intensity of the operator. At the same time, during the process of aligning the mounting hole 21 with the hinge hole 3221 on the second hinge part 322, the operator can accurately locate the position of the mounting hole 21 by moving the position of the hook part 22 on the shaft 36, so as to quickly find and dock the hinge hole 3221 on the second hinge part 322.

[0061] In a feasible implementation, the number of the shaft rods 36 can be set to at least two, and each shaft rod 36 can be arranged at intervals. Correspondingly, a plurality of hook portions 22 are arranged on the side of the display module 2 opposite to the rear cover module 3, and the number of the hook portions 22 corresponds to the number of the shaft rods 36, and each hook portion 22 is also arranged at intervals and corresponds to the position of the shaft rod 36. The plurality of shaft rods 36 and the plurality of hook portions 22 work together to bear the weight of the display module 2, which can reduce the stress of a single hook and thus reduce the risk of damage, and can also provide more uniform support for the display module 2, reduce the tilt or offset of the display module 2, and improve the stability of the overall structure. At the same time, the design of multiple hooks can also improve the durability of the connection system. Even if one hook has a problem, the other hooks can still maintain the connection.

[0062] It should be particularly pointed out that when there are multiple shaft rods 36 , the center line of each shaft rod 36 must coincide with the center line of the connecting rod in the screen connector 32 .

[0063] Optionally, there are two shaft rods 36. With reference to the two side frames of the rear cover module 3, the two shaft rods 36 are basically symmetrically arranged on the opposite sides of the rear cover module 3, and the center lines of the two shaft rods 36 are kept coincident with the center line of the connecting rod in the screen connector 32.

[0064] In order to further improve the stability of the front cover module 1 and the display module 2 when flipping, in a feasible implementation, the front cover pneumatic rod 11 can be set to two, and the two front cover pneumatic rods 11 are respectively set on both sides of the front cover module 1. The two front cover pneumatic rods 11 can provide a more balanced support force and reduce the tilt or imbalance of the front cover module 1 when opening or closing. At the same time, the two front cover pneumatic rods 11 work together to provide greater support force, which is suitable for scenarios that need to support a heavier front cover module 1. It should be pointed out that when the number of the front cover pneumatic rods 11 is two, the first support member 12 and the second support member 33 also need to be set to two groups to respectively connect the above-mentioned two front cover pneumatic rods 11.

[0065] Optionally, the screen pneumatic rod 13 can be set to two, and the two screen pneumatic rods 13 are respectively set on both sides of the display module 2. The two screen pneumatic rods 13 can provide a more balanced support force to reduce the tilt or imbalance of the display module 2 when it is opened or closed. At the same time, the two screen pneumatic rods 13 work together to provide greater support force, which is suitable for scenes that need to support heavier display modules 2. It should be noted that when the number of screen pneumatic rods 13 is two, the third support member 14 and the fourth support member 34 also need to be set to two groups to respectively connect the above-mentioned two screen pneumatic rods 13.

[0066] Optionally, the number of the front cover connectors 31 can be at least two, and the front cover connectors 31 are arranged at intervals, and the center lines of the rotating shafts 311 in the front cover connectors 31 coincide with each other. Multiple front cover connectors 31 can provide a more stable connection for the front cover module 1, reduce the shaking of the front cover module 1 during use, and can more evenly distribute the weight of the front cover module 1, avoiding excessive local stress due to load concentration.

[0067] Optionally, the number of screen connectors 32 can be at least two, each of which is spaced apart, and the center lines of the connecting rods in each of the screen connectors 32 coincide with each other. Multiple screen connectors 32 can provide a more stable connection for the display module 2, reduce the shaking of the display module 2 during use, and more evenly distribute the weight of the display module 2, avoiding excessive local stress due to load concentration.

[0068] It can be seen from this that the technical solution provided by the present application, the display device is composed of a front cover module, a display module and a rear cover module. The top of the rear cover module is designed with a front cover connector and a screen connector to connect the front cover module and the display module respectively, and the front cover connector and the screen connector are both rotatable parts. In this way, the front cover module and the display module can be turned outward independently of the rear cover module with the top of the rear cover module as the rotation reference point. Since the display module and the front cover module are located on the same side of the rear cover module, and the display module is arranged between the front cover module and the rear cover module. Therefore, when the operator needs to repair or replace electronic components, it is not necessary to remove the entire machine from the original fixed position. It is only necessary to open the front cover module separately according to actual needs, or open the front cover module and the display module in the same direction at the same time, so that various electronic components inside the display device can be exposed, so as to facilitate the operator to repair or replace various electronic components. At the same time, the flip angle of the display module is smaller than that of the front cover module, which can avoid the front cover module from obstructing the display module during the flipping process. The flip connection solution provided by the present application not only simplifies the maintenance process and reduces the equipment maintenance time, but also reduces the risk of damage to the equipment caused by frequent disassembly and assembly.

[0069] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
