Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a bottom shell of a display module, a display module and a splicing screen. Background Art

[0002] With the popularity of naked-eye 3D display screens, customers have an increasing demand for corner screens. When conventional-sized modules are spliced into corner screens or special-shaped screens, there are large corner gaps. Small-sized modules can better achieve the arc transition of corner screens, giving people a three-dimensional visual experience. Therefore, the demand for small-sized modules has also increased. The existing bottom shells of small-sized modules are conventional four-sided bevel and two-sided bevel bottom shells. Without support, the screw locking holes are located at the corners (bevel surfaces). When locking, without a jig to support the bottom of the bevel surface, the module will warp and slip. The jig developed to fit the bevel surface of the bottom shell needs to have an entire bevel surface. The bevel surface of the jig supports the bevel surface of the bottom shell. The accuracy requirement for the bevel surface of the jig is high, the cost of the jig is high, and during the actual production and assembly process, due to the plastic characteristics of the bottom shell, there will be problems such as non-contact or inaccurate positioning between the bevel surface of the jig and the bevel surface of the bottom shell. This causes problems such as locking and lighting, or abnormal locking of the module. Summary of the Utility Model

[0003] To solve the above problems, the purpose of the utility model is to provide a bottom shell of a display module, a display module and a splicing screen.

[0004] The utility model is implemented as follows: A bottom shell of a display module includes a bottom shell body of the module. The side of the bottom shell body of the module is set as a bevel surface. The front of the bottom shell body of the module is provided with a plurality of screw locking holes. On the outer bevel surface of each side, there is a support groove recessed into the bottom shell of the module. The end surface of the support groove close to the front of the bottom shell body of the module is parallel to the front of the bottom shell body of the module. The screw locking holes are adjacent to or opposite to the support grooves.

[0005] Preferably, a hanging platform is provided on the back of the bottom shell body of the module.

[0006] Preferably, the hanging platform is U-shaped. The open end of the U-shaped hanging platform faces the back of the bottom shell body of the module. The end surfaces of both sides of the open end of the U-shaped hanging platform are fixedly connected to the back of the bottom shell body of the module.

[0007] Preferably, the plane of the hanging platform parallel to the short side of the bottom shell body of the module is perpendicular to the plane where the back of the bottom shell body of the module is located.

[0008] Preferably, the hanging platform and the back of the bottom shell body of the module are integrally formed.

[0009] Preferably, a plurality of the support grooves are arranged at intervals on each bevel surface.

[0010] Preferably, one supporting groove is respectively provided on the inclined surfaces on both sides of the connection between two adjacent inclined surfaces of the module bottom shell.

[0011] Preferably, the locking screw hole is provided at each corner of the front side of the module bottom shell body, and the locking screw hole is located between the supporting grooves on both sides of the connection between the two inclined surfaces.

[0012] Preferably, the inwardly concave supporting groove forms an inwardly convex mounting portion on the inner side inclined surface of the module bottom shell body, and the locking screw hole is arranged on the end surface of the mounting portion facing the front side of the module bottom shell body.

[0013] A display module comprises a display panel, and adopts the display module bottom shell as described in any one of the above items, wherein the display panel is fixed to the front side of the display module bottom shell.

[0014] A spliced ​​screen is formed by splicing two or more display modules; the spliced ​​screen is a corner screen or a special-shaped screen.

[0015] The beneficial effects of the present invention are as follows: the present invention provides a display module bottom shell. Compared with the prior art, the present invention has at least the following technical effects: 1. By providing an inwardly concave support groove on the outer side surface of the side edge of the module bottom shell body which is set as an inclined surface, the end surface of the support groove and the front side of the module bottom shell body which is parallel to each other can contact with the jig and have a supporting function. Compared with only using an inclined surface for support, the jig does not need to be designed as an inclined surface, and only needs to provide a few support ribs matching the support groove, which can reduce the accuracy requirements of the jig. The contact surface between the jig and the support groove changes from an inclined surface to a flat contact surface, which is more stable and reliable. In this way, the problems of inability to contact and inaccurate positioning caused by plastic deformation can be avoided, and the entire module bottom shell body will not tilt and slip when locking the screws on one side, thereby avoiding the problems of lighting and abnormal locking. 2. The conventional bottom shell has an aging groove on the side, and the upper and lower clamps of the aging rack are used to press the aging, but the inclined module bottom shell cannot be clamped and fixed, so the aging test cannot be performed; for this reason, a hanging platform is set on the back of the module bottom shell of the utility model, and the module can be directly hung on the aging test rack, which solves the problem that the inclined surface cannot be aged. 3. Multiple support grooves are set to support multiple positions when screwing, so as to avoid the situation of warping during locking, causing the locking light and abnormal locking. 4. A support groove is set on both sides of the connection between the two adjacent inclined surfaces, which can play a role in supporting and dispersing the force when the screws are locked in the locking screw holes at the angle. Compared with the original method that only the inclined surface supports the uncertainty of warping and skewing in two directions, the support grooves on both sides of this method play a supporting and limiting role on the two inclined side edges when locking the screws to ensure that the module is fixed without warping and displacement, and further avoid the situation of locking light and abnormal locking.

[0016] A display module. Compared with the prior art, the present utility model has at least the following technical effects: The above-mentioned display module bottom shell is used to fix the display panel, which plays a role of stable support during locking, avoiding the bottom shell from warping during locking, and effectively avoiding the occurrence of locking lamp-on and other abnormal locking situations.

[0017] A splicing screen. Compared with the prior art, the present utility model has at least the following technical effects: The above-mentioned display module bottom shell is used to fix the display panel, which plays a role of stable support during splicing and locking, avoiding the bottom shell from warping during locking, and effectively avoiding the occurrence of locking lamp-on and other abnormal splicing and locking situations.

[0022] The following further describes the present utility model with reference to the drawings and specific embodiments.

[0023] Please refer to Figures 1 to 3 , a display module bottom shell, including a module bottom shell body 1. The side of the module bottom shell body 1 is set as an inclined surface. A plurality of screw locking holes 2 are arranged on the front surface of the module bottom shell body 1. An inwardly concave support groove 3 is provided on the outer inclined surface of each side towards the inside of the module bottom shell. The end surface of the support groove 3 close to the front surface of the module bottom shell body 1 is parallel to the front surface of the module bottom shell body 1. The screw locking hole 2 is adjacent to or opposite to the support groove 3. By providing an inwardly concave support groove 3 on the outer side surface of the side of the module bottom shell body 1 that is set as an inclined surface, the end surface of the support groove 3 parallel to the front surface of the module bottom shell body 1 can contact the jig, playing a supporting role. Compared with only using the inclined surface for support, the jig does not need to be designed as an inclined surface, and only a few support ribs matching the support groove 3 need to be provided, which can reduce the precision requirements of the jig. The contact surface between the jig and the support groove 3 changes from an inclined surface to a flat contact surface, which is more stable and reliable. In this way, problems such as inability to contact and inaccurate positioning caused by plastic deformation can be avoided, and the situation where the entire module bottom shell body 1 warps and slips when locking one side of the screw can also be avoided, thereby avoiding the problems of locking lamp-on and abnormal locking.

[0024] Please refer to Figures 1 to 3 , preferably, a hanging platform 4 is provided on the back surface of the module bottom shell body 1. The hanging platform 4 is U-shaped, the open end of the U-shape of the hanging platform 4 faces the back surface of the module bottom shell body 1, and the end faces of both sides of the open end of the U-shape of the hanging platform 4 are fixedly connected to the back surface of the module bottom shell body 1. The surface of the hanging platform 4 parallel to the short side of the module bottom shell body 1 is perpendicular to the plane where the back surface of the module bottom body is located. The hanging platform 4 is integrally formed with the back surface of the module bottom shell body 1. For a conventional bottom shell, an aging groove is opened on the side surface, and the upper and lower clamping pieces of the aging rack are used to press and age it. However, the inclined module bottom shell cannot be clamped and fixed, so the aging test cannot be carried out. Therefore, a hanging platform 4 is provided on the back surface of the module bottom shell of the present invention, and the module can be directly hung on the aging test rack, solving the problem that the inclined surface cannot be aged.

[0025] Please refer to Figures 1 to 3 , preferably, a plurality of the support grooves 3 are arranged at intervals on each of the inclined surfaces. It is convenient to set a plurality of screw holes 2 to support when screwing at multiple positions, and to avoid the situation of warping during screwing, resulting in abnormal lighting and abnormal screwing.

[0026] Please refer to Figures 1 to 3 , preferably, one of the support grooves 3 is respectively arranged on the two inclined surfaces at the connection of two adjacent inclined surfaces of the module bottom shell. The locking screw holes 2 are arranged at each corner of the front surface of the module bottom shell body 1, and the locking screw holes 2 are located between the support grooves 3 on both sides of the connection of the two inclined surfaces. By respectively arranging a side support groove 3 on both sides at the connection of two adjacent inclined surfaces, it can play a role in supporting and dispersing the force when screwing the locking screw holes 2 at the included angle. Compared with the original situation where there are uncertainties of warping and skewing in two directions with only the inclined surface support, in this way, the support grooves 3 on both sides play a role of supporting and limiting the two inclined surface sides when screwing the screws, ensuring that the module is fixed without warping and displacement, and further avoiding the occurrence of abnormal lighting and abnormal screwing.

[0027] Please refer to Figures 1 to 2 , preferably, an inner convex mounting portion 5 is formed on the inner inclined surface of the module bottom shell body 1 in the concave support groove 3, and the locking screw hole 2 is arranged on the end surface of the mounting portion 5 facing the front surface of the module bottom shell body 1. It is convenient to arrange the locking screw holes 2.

[0028] A display module includes a display panel and adopts the display module bottom shell as described in any one of the above. The display panel is fixed to the front surface of the display module bottom shell.

[0029] A splicing screen is formed by splicing two or more display modules; the splicing screen is a corner screen or a special-shaped screen.

[0030] The utility model has the following working principle:

[0031] During assembly, the module bottom shell body 1 and the jig can be fixed by docking the support ribs on the jig with the corresponding support grooves 3 of the module bottom shell body 1, and then the screw locking and other steps can be performed. The contact surface between the support groove 3 and the jig is a horizontal plane, which can provide support and prevent warping, avoiding the problem of screw lighting or abnormal locking due to warping during the screw locking process caused by the inclined frame.

[0032] When an aging test is required, the module is hung on an aging test rack through the hanging platform 4 on the back of the module bottom shell body 1 to perform the aging test.
