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] The existing display device is generally composed of a front cover module, a display module and a rear cover module, and the modules are usually connected by bolts.

[0003] However, there are some structural problems when users replace and install modules. For example, when disassembling a display module, multiple installers are required to manually lift the display module to remove it, and when installing a new module, the installers need to constantly lift the heavy module to find the hinge positioning holes, which is not only time-consuming and labor-intensive, but also poses certain safety risks.

[0004] Therefore, how to improve the installation method of the internal modules of 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, which can quickly and conveniently install and replace modules inside the display device.

[0006] To achieve the above-mentioned purpose, the present application provides a display device on one hand, which includes at least a display module and a back cover module, wherein a connecting member and a shaft rod are arranged on the top of the back cover module, the connecting member is a rotatable component, the back cover module is pivotally connected to the display module through the connecting member, and the rotation axis of the connecting member coincides with the center line of the shaft rod; a hook portion is arranged on the side of the display module opposite to the back cover module, the groove on the hook portion matches the shaft rod, and the groove on the hook portion is suspended and connected with the shaft rod to hang the display module on the back cover module.

[0007] It can be seen that the technical solution provided by the present application is that the back cover module and the display module are connected by a connector. The connector is arranged at the top of the back cover module, and the connector is a rotatable component. After the display module is connected to the back cover module through the connector, the display module can rotate around the rotation axis of the connector. In this way, when the display module is flipped, the angle between the top of the display module and the top of the back cover module will change, which can facilitate the technicians to maintain the equipment inside the display device. Furthermore, a shaft rod is also arranged at the top of the back cover module, and a hook part is correspondingly arranged on the side of the display module facing the back cover module. During the replacement and installation of the display module, the operator can use the hook part to hang the display module on the shaft rod, so as to use the hook part to effectively bear the weight of the display module and prevent the module from falling, thereby protecting the safety of the operator and the equipment during the disassembly and assembly process. At the same time, the operator can also carefully move the display module by adjusting the position of the hook part on the shaft rod until the hinge hole on the display module is accurately aligned with the hinge hole on the back cover module. The solution of the present application only requires two operators to complete the replacement of the module, and through the coordinated action of the hook part and the shaft rod, the operator can fine-tune the position of the module on a stable platform to ensure the accurate docking of the hinge holes, thereby achieving fast and stable installation of the module.

[0015] 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.

[0016] 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.

[0017] With the continuous development of business, various display devices have been widely used. As a key information dissemination and interactive tool, the performance and maintenance efficiency of display devices have an important impact on the user experience. Through the analysis of display devices on the market, it can be found that existing display devices are usually composed of a front cover module, a display module and a rear cover module. The rear cover module is generally fixed on the wall, and the display module and the front cover module are connected to the rear cover module. The front cover module covers the front of the display module to provide protection for the display module. These modules are fixed by mechanical connections such as bolts.

[0018] Although the above structural design can ensure the stability of the connection between modules, it faces a series of problems during the module replacement and installation process. For example, when disassembling the display module, it is necessary to manually lift the module in order to remove the hinge, which not only increases the labor intensity of the operator, but also increases the risk of the module falling. In the process of installing a new module, due to the lack of an effective load-bearing and positioning mechanism, multiple operators are required to manually lift the heavy module and constantly adjust the position of the module to find and align the hinge positioning holes. Usually, it takes three or more operators to dismantle or replace a module, which not only increases labor costs but also reduces work efficiency.

[0019] Therefore, how to design a faster and more convenient module installation solution to improve the safety, efficiency and accuracy when disassembling and assembling the modules has become an issue that needs to be urgently addressed in this field.

[0020] 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.

[0021] 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.

[0022] Please also see Figures 1 to 6 As shown, in an achievable embodiment, the display device at least includes a display module 1 and a back cover module 2, and the connecting mechanism 3 includes a connecting member 31, a shaft 32 and a hook portion 33, wherein the connecting member 31 and the shaft 32 are simultaneously arranged on the top of the back cover module 2. The connecting member 31 is a rotatable component, and its specific structure can refer to components such as hinges and hinges. The back cover module 2 is pivotally connected to the display module 1 through the connecting member 31. In other words, after the display module 1 is connected to the back cover module 2 through the connecting member 31, the display module 1 can rotate around the rotation axis of the connecting member 31. It should be noted that the connecting member 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 connecting member 31. The rotation axis of the connecting member 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.

[0023] In practical applications, Figure 1The perspective shown is for reference, and the connecting member 31 is installed on the top of the rear cover module 2 in a state of being horizontal to the ground, and the rotation axis of the connecting member 31 is also horizontal to the ground. The shaft 32 can adopt a cylindrical structure, a nearly cylindrical structure or other geometric structures with an arc-shaped surface, and the shaft 32 has a center line, and the center line of the shaft 32 extends along the length direction of the shaft 32. For example, when the shaft 32 is a cylindrical shaft, the center line of the shaft 32 is a straight line where its central symmetry axis is located. When the shaft 32 is a semi-cylindrical shaft, the center line of the shaft 32 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 32 is installed on the top of the rear cover module 2, the center line of the shaft 32 coincides with the rotation axis of the connecting member 31. It should be pointed out that when understanding the center line of the shaft 32, the shaft 32 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, and the straight line can be regarded as the center line of the shaft 32.

[0024] In this embodiment, the hook portion 33 is located on the side of the display module 1 opposite to the back cover module 2, that is, after the display module 1 is connected to the back cover module 2, the hook portion 33 is installed on the side of the display module 1 facing the back cover module 2. The hook portion 33 can be constructed as a thin plate structure, which is fixed to the frame of the display module 1 by riveting or bolting. A groove 331 is provided on the hook portion 33, and the opening direction of the groove 331 faces the ground. Further, the cross-sectional shape of the groove 331 matches the cross-sectional shape of the shaft 32. Specifically, the cross-sectional shape of the groove 331 can be an arc or a semicircle, and its radius is greater than the radius of the shaft 32. In this way, after the groove 331 is suspended and connected to the shaft 32, the hook portion 33 can rotate around the center line of the shaft 32.

[0025] During the installation of the display module 1, the operator can first hang the groove 331 on the shaft 32, and then hang the display module 1 on the shaft 32, so that the display module 1 can be hung on the back cover module 2. Under the cooperation of the hook part 33 and the shaft 32, the hook part 33 can effectively bear the weight of the display module 1, avoiding the display module 1 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 1, since the display module 1 is hung on the shaft 32, the weight of the display module 1 is borne by the shaft 32, so when the operator disassembles the connector 31, there is no need to worry that the display module 1 will suddenly fall from the back cover module 2.

[0026] Since the display module 1 can rotate around the rotation axis of the connecting member 31, the hook portion 33 can rotate around the center line of the shaft 32, and the center line of the shaft 32 coincides with the rotation axis of the connecting member 31, when the display module 1 rotates around the rotation axis of the connecting member 31, the hook portion 33 can also rotate around the center line of the shaft 32, that is, the hook portion 33 can rotate synchronously with the connecting member 31. The above structure can ensure that the hook portion 33 will not hinder the flipping of the display module 1, and can also use the hook portion 33 to share the weight of the display module 1.

[0027] In an achievable embodiment, the connecting member 31 includes a connecting rod (not shown), a first hinge portion 311 and a second hinge portion 312. The first hinge portion 311 can be fixedly connected to the housing of the rear cover module 2 by bolts, and an axial hole is provided on the first hinge portion 311 and the second hinge portion 312, and the connecting rod is inserted into the axial hole of the first hinge portion 311 and the axial hole of the second hinge portion 312 at the same time. The first hinge portion 311, the second hinge portion 312 and the connecting rod together constitute a hinge structure, so that the second hinge portion 312 is rotatably connected to the first hinge portion 311 with the connecting rod as the rotation axis, and the straight line where the center line of the connecting rod is located is the rotation axis of the connecting member 31.

[0028] The second hinge portion 312 is provided with a hinge hole 3121, and a screw hole 34 is provided on a side of the display module 1 opposite to the rear cover module 2. The screw hole 34 and the hinge hole 3121 cooperate with each other. When the operator needs to install the display module 1 on the rear cover module 2, he can first align the screw hole 34 with the hinge hole 3121, and then insert the screw rod into the screw hole 34 and the hinge hole 3121 in sequence, thereby fixing the display module 1 on the rear cover module 2.

[0029] Optionally, in a feasible implementation, two or more hinge holes 3121 may be provided on the second hinge portion 312, and the number of screw holes 34 corresponds to the number of hinge holes 3121, so that the display module 1 can be fixed to the back cover module 2 using multiple screws to improve the stability of the connection between the display module 1 and the back cover module 2.

[0030] It should be particularly pointed out that, during the installation of the display module 1, the operator first hangs the groove 331 on the shaft 32, and the weight of the display module 1 is borne by the shaft 32. Therefore, when the display module 1 and the rear cover module 2 are subsequently connected by the screw, the operator does not need to hold the display module 1 all the time, which can significantly reduce the labor intensity of the operator. At the same time, during the process of aligning the screw hole 34 with the hinge hole 3121, the operator can accurately locate the position of the screw hole 34 by moving the position of the hook part 33 on the shaft 32, so as to quickly find and align the hinge hole 3121.

[0031] In a feasible embodiment, the connecting member 31 also includes a reinforcing plate 313. In order to improve the structural strength of the reinforcing plate 313, the reinforcing plate 313 can adopt a triangular bracket structure and be made of metal material. The first end 3131 of the reinforcing plate 313 can be fixedly connected to the shell of the rear cover module 2 by riveting or welding, and the second end 3132 of the reinforcing plate 313 can be used to install the first hinge part 311, that is, the first hinge part 311 can be connected to the shell of the rear cover module 2 through the reinforcing plate 313. This design can improve the connection stability between the first hinge part 311 and the rear cover module 2. Furthermore, on the premise of ensuring the structural strength of the reinforcing plate 313, a number of holes can be opened on the reinforcing plate 313 for lightweight design.

[0032] In actual applications, since a large number of electrical components are installed inside the back cover module 2, and for heat dissipation considerations, after the display module 1 and the back cover module 2 are assembled together, a certain gap is usually left between the display module 1 and the back cover module 2. This requires special design of the installation parameters between the display module 1 and the second hinge portion 312 to avoid the display module 1 from being in close contact with the shell surface of the back cover module 2. To this end, the second end 3132 of the reinforcing plate 313 can protrude outwardly from the shell surface of the back cover module 2 by a certain distance, and the first hinge portion 311 is fixedly connected to the second end 3132 of the reinforcing plate 313, so that the second hinge portion 312 can protrude from the shell surface of the back cover module 2 by a certain distance. In this way, when the display module 1 is connected to the back cover module 2 through the second hinge portion 312, the display module 1 can be prevented from being in close contact with the shell surface of the back cover module 2.

[0033] Since both the first hinge portion 311 and the second hinge portion 312 protrude a certain distance from the shell surface of the rear cover module 2, in order to ensure that the center line of the shaft 32 coincides with the rotation axis of the connecting member 31, the shaft 32 also needs to protrude a certain distance from the shell surface of the rear cover module 2. To this end, in a feasible embodiment, a support frame 21 is provided on the rear cover module 2, and the support frame 21 includes a first support arm 211 and a second support arm 212. The first support arm 211 can adopt a triangular or trapezoidal structure, one end of which is fixedly connected to the shell surface of the rear cover module 2, and the other end protrudes outwardly from the shell surface of the rear cover module 2 by a certain distance and is provided with a hole. The structure and installation method of the second support arm 212 can refer to the first support arm 211, and will not be repeated here.

[0034] The first support arm 211 and the second support arm 212 are parallel to each other, and the distance between the first support arm 211 and the second support arm 212 can be set with reference to the length of the shaft 32. The two ends of the shaft 32 are respectively connected to the first support arm 211 and the second support arm 212. Specifically, the two ends of the shaft 32 can be inserted into the holes of the first support arm 211 and the second support arm 212 respectively.

[0035] It should be pointed out in particular that the distance that the first support arm 211 and the second support arm 212 protrude from the shell surface of the rear cover module 2 can be set according to the distance that the second hinge part 312 protrudes from the shell surface of the rear cover module 2. It only needs to be ensured that when the shaft rod 32 is connected to the first support arm 211 and the second support arm 212, the center line of the shaft rod 32 coincides with the rotation axis of the connecting member 31 (that is, the center line of the connecting rod).

[0036] In practical applications, the weight of the display module 1 is generally large. If the rear cover module 2 and the display module 1 are connected only by the connecting member 31, there may be a problem of insufficient supporting force, which may easily cause the display module 1 to loosen or fall off during use. To solve the above problem, in an achievable implementation, the number of connecting members 31 can be set to at least two, and multiple connecting members 31 are arranged at intervals on the top of the rear cover module 2, and the rotation axes of each connecting member 31 coincide with each other. For example, when the connecting member 31 is composed of a connecting rod, a first hinge portion 311 and a second hinge portion 312, the center lines of the connecting rods in each connecting member 31 should be on a straight line.

[0037] Correspondingly, the display module 1 and the rear cover module 2 have a plurality of mounting holes on the side opposite to each other, and the plurality of mounting holes are used to cooperate with the hinge holes on each connecting member 31, so that the operator can use a screw to connect the display module 1 and the second connecting member 35 together. In this embodiment, the rear cover module 2 is pivotally connected to the display module 1 through a plurality of connecting members 31, that is, the display module 1 is connected to the rear cover module 2 by using a plurality of connecting members 31 at the same time. In the above structure, each connecting member 31 can be used as a connecting point, and the weight of the display module 1 is shared by a plurality of connecting points, which can reduce the stress concentration at a single connecting point, thereby reducing the risk of structural damage.

[0038] Optionally, when there are two connectors 31, with the two side frames of the rear cover module 2 as a reference, the two connectors 31 are basically symmetrically arranged on the opposite sides of the top of the rear cover module 2 to more evenly disperse the weight of the display module 1 and the external force it receives, thereby enhancing the stability of the overall structure. Furthermore, the shaft 32 can be arranged near the symmetry center of the two connectors 31, so that when the display module 1 is suspended on the shaft 32 using the hook portion 33, the center of gravity of the display module 1 can be balanced, reducing instability caused by the center of gravity offset. At the same time, in order to avoid interference between the two connectors 31 and the hook portion 33 when the display module 1 rotates, it is necessary to ensure that the rotation axis of the two connectors 31 coincides with the center line of the shaft 32.

[0039] To further improve the stability of the overall structure, in a feasible implementation, a plurality of shafts 32 may be provided on the top of the rear cover module 2 , the plurality of shafts 32 are arranged at intervals, and the rotation axis of each connecting member 31 coincides with the center line of each shaft 32 .

[0040] Optionally, when there are two shaft rods 32, with the two side frames of the rear cover module 2 as a reference, the two shaft rods 32 are basically symmetrically arranged on the opposite sides of the top of the rear cover module 2, and the center lines of the above two shaft rods 32 need to coincide with the rotation axis of each connecting member 31.

[0041] Optionally, a plurality of hook portions 37 are provided on the side of the display module 1 opposite to the back cover module 2, and the number of the hook portions 37 corresponds to the number of the shaft rods 32, and each hook portion 37 is used to be mounted on a shaft rod 32, that is, there are no extra hook portions 37 or shaft rods 32, and each hook portion 37 is matched with exactly one shaft rod 32, and vice versa. This embodiment uses multiple hooks to provide more uniform support, which can reduce the tilt or offset of the display module 1 and improve the stability of the overall structure. At the same time, by sharing the weight and force of the display module 1 with multiple hooks, the stress of a single hook can be reduced, thereby reducing the risk of damage. The design of multiple hooks can also improve the durability of the connection system. Even if one hook has a problem, the other can still maintain the connection.

[0042] It should be particularly noted that, since the rotation axis of each connecting member 31 coincides with the center line of each shaft 32 , when the display module 1 rotates, the rotation of each connecting member 31 and each hook portion 33 will not interfere, and the display module 1 can be turned over normally.

[0043] Optionally, when there are two connectors 31 and two shafts 32, the two shafts 32 can be respectively arranged at the two ends of the top of the rear cover module 2, and then the two connectors 31 are arranged between the two shafts 32. Of course, the two connectors 31 can also be respectively arranged at the two ends of the top of the rear cover module 2, and then the two shafts 32 are arranged between the two connectors 31.

[0044] It can be seen that the technical solution provided by the present application is that the back cover module and the display module are connected by a connector. The connector is arranged at the top of the back cover module, and the connector is a rotatable component. After the display module is connected to the back cover module through the connector, the display module can rotate around the rotation axis of the connector. In this way, when the display module is flipped, the angle between the top of the display module and the top of the back cover module will change, which can facilitate the technicians to maintain the equipment inside the display device. Furthermore, a shaft rod is also arranged at the top of the back cover module, and a hook part is correspondingly arranged on the side of the display module facing the back cover module. During the replacement and installation of the display module, the operator can use the hook part to hang the display module on the shaft rod, so as to use the hook part to effectively bear the weight of the display module and prevent the module from falling, thereby protecting the safety of the operator and the equipment during the disassembly and assembly process. At the same time, the operator can also carefully move the display module by adjusting the position of the hook part on the shaft rod until the hinge hole on the display module is accurately aligned with the hinge hole on the back cover module. The solution of the present application only requires two operators to complete the replacement of the module, and through the coordinated action of the hook part and the shaft rod, the operator can fine-tune the position of the module on a stable platform to ensure the accurate docking of the hinge holes, thereby achieving fast and stable installation of the module.

[0045] 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.
