[0002] In the production of display screen frames, it is necessary to formulate the display screen frames according to the different sizes of the customer's device display frames and the size of the display screen. However, the actual required display screen size does not necessarily match the size of the device display frame. For example, an 80*100mm display screen area is sufficient, but the customer's device display frame size is 80*150mm. Hard matching will increase unnecessary costs. Therefore, it is necessary to locate the relative position between the smaller display screen and the display screen frame corresponding to the device display frame size. The existing alignment method is to align the display screen with the display screen through the notches at the four corners of the display screen frame. This method often produces a large number of poor alignment, resulting in incomplete display images on the display screen and inability to work normally. Repeated disassembly and assembly further leads to repeated twisting of the feet, resulting in material waste. Utility Model Content

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0029] Embodiment 1
[0030] Please refer to Figure 1 The present embodiment provides a display screen frame 1, comprising a front panel 2 and side panels vertically arranged at the edge of the front panel 2, the middle of the front panel 2 is a rectangular window 3 for leaking a display screen 13; in the present embodiment, the display screen frame 1 is a frame for installing a rectangular display module, that is, the side panels are composed of four side panels, surrounded in a rectangular shape. The side panels include a first side panel 6 and a second side panel 4 respectively arranged in groups and opposite to each other, and the second side panel 4 is spaced apart from the first side panel 6.
[0031] A positioning block 7 for limiting the display screen 13 is disposed on the first side plate 6 , and the positioning block 7 protrudes inwards.
[0032] In this embodiment, the display screen frame 1 preferably uses a 0.6 mm thick metal plate. The trapezoidal protrusion on the first side panel 6 is stamped into the interior of the display screen frame 1 through a stamping process. The size of the trapezoidal protrusion is preferably 2 mm on the upper bottom, 4 mm on the lower bottom, and 1.5 mm in height. Under this size condition, the metal plate is simple to form, not easy to crack, easy to process and manufacture, and has a beautiful appearance.
[0033] The second side panel 4 is provided with a twist foot 8 for fixing the display screen 13. The twist foot 8 is an L-shaped metal sheet integrated with the second side panel 4. The vertical side 10 of the L-shaped metal sheet is integrated with the second side panel 4 and is perpendicular to the plane where the front panel 2 is located. The horizontal side 9 of the L-shaped metal sheet is parallel to the plane where the front panel 2 is located, and a bending groove 11 is opened at the root of the horizontal side 9 of the L-shaped metal sheet.
[0034] An inwardly protruding reinforcing rib 5 is provided on the front plate 2 near the second side plate 4 , and the reinforcing rib 5 is parallel to the second side plate 4 .
[0035] Embodiment 2
[0036] Please refer to Figures 2 to 5 The present embodiment provides a display module, comprising the display screen frame 1 described in the first embodiment. The display module comprises a buffer pad 14, a display screen 13, a backlight source 15 and a driving circuit board 12 which are sequentially arranged inside the display screen frame 1. The display screen 13 is a display component, the backlight source 15 is a lighting device, the backlight source 15 is fixedly arranged on the driving circuit board 12, and the driving circuit board and the display screen 13 are electrically connected through a conductive adhesive strip 16; the distance between the positioning blocks 7 on the first side panels 6 arranged in groups is adapted to the length of the display screen 13, and the distance between the second side panels 4 arranged in groups is adapted to the width of the display screen 13.
[0037] The assembly process of this embodiment is as follows: the display screen frame 1 is inverted on the workbench with the side panel facing upwards, and the buffer gasket 14 is first placed at a position corresponding to the reinforcing rib 5 on the front panel 2, and then the display screen 13 is placed in the display screen frame 1, so that the display screen 13 is facing downwards and aligned with the window 3 of the front panel 2, and the buffer gasket 14 just falls into the step on the side of the display screen 13 facing the front panel 2. Then, a conductive rubber strip 16 is placed close to the second side panel 4 on the step on the side of the display screen 13 away from the front panel 2, and then the backlight source 15 and the driving circuit board welded together are buckled on the display screen frame 1, and the twist pin 8 of the display screen frame 1 is aligned with the notch on the driving circuit board, so that the twist pin 8 passes through the driving circuit board, and a certain external force is applied downwards to the driving circuit board to press the conductive rubber strip 16, so that the display screen 13 is fixed in position under the pressure of the buffer gasket 14 and the conductive rubber strip 16 on both sides. Then, external force is used to twist the horizontal side 9 of the twist foot 8 along the bending line 17 at the bending notch 11 by a certain angle, so that a part of the horizontal side 9 is twisted to the part of the driving circuit board 12 located inside the display screen frame 1, thereby squeezing the back side of the driving circuit board 12, thereby completing the assembly of the display module.
[0038] The bending notch 11 provided at the root of the horizontal edge 9 reduces the difficulty of twisting the horizontal edge 9 on the one hand, and prevents the burrs at the root of the horizontal edge 9 from scratching the driving circuit board during processing on the other hand.
[0039] The buffer gasket 14 is arranged between the step of the display screen 13 and the reinforcing rib 5 of the front panel 2, and plays a buffering role in preventing the display screen 13 from shifting and the force acting thereon, and has a good vibration isolation and buffering effect, avoiding hard contact between the display screen 13 and the front panel 2, and plays a good vibration isolation and buffering effect in harsh vibration and impact environments, and can effectively protect the display screen 13.
[0040] In addition, a deformation seam is reserved between the adjacent first side panels 6 and second side panels 4. During assembly, the first side panels 6 and second side panels 4 can be slightly tilted outward, which is beneficial to the installation of the display screen 13 and prevents damage to the display screen 13 due to forced installation when the positioning is not correct.
[0041] It should be noted that the shape of the side panels of the present invention is consistent with the shape of the display screen 13 to be installed, and is therefore not limited to a rectangle. However, the conventional display screen 13 is generally a rectangle, so the present invention is only described using a rectangle as an example, and display screens 13 of any other shape are applicable and are within the protection scope of the present invention.
[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; 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 the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0043] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).
[0044] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
[0045] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
