[0023] The present application will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without making creative changes are within the protection scope of the present application.

[0024] Currently, common elevator landing displays in the elevator industry include a frame 1, a display, and a main board 2. The display and main board 2 are mounted on the frame 1 and connected by wiring. This application aims to improve the assembly structure of the main board 2 with the frame 1 and main board 2 of the elevator landing control device. Figure 1 , 2 As shown in Figures 4 and 5, the quick-assembly elevator landing display provided in this application includes a frame 1 and a mainboard 2 installed within the frame 1.

[0025] A support frame is provided within the frame 1. An upper positioning block 11 is provided at one end of the frame 1. The height of the gap between the upper positioning block 11 and the support frame matches the thickness of the motherboard 2. Thus, one end of the motherboard 2 is clamped and positioned between the upper positioning block 11 and the support frame, preventing the motherboard 2 from moving in its thickness direction. A limiting protrusion 12 is provided on the side wall of the frame 1, and an assembly groove matching the limiting protrusion 12 is provided on the motherboard 2. The limiting protrusion 12 cooperates with the assembly groove on the motherboard 2, preventing the motherboard 2 from moving in its length direction. An elastic locking block 13 is also provided on the side wall of the frame 1. The elastic locking block 13 is configured to pop out or retract in the width direction of the frame 1, and the motherboard 2 is locked between the elastic locking block 13 and the support frame. After the motherboard 2 is assembled, it is locked and clamped between the elastic locking block 13 and the support frame, preventing the other end of the motherboard 2 from moving in its thickness direction.

[0026] During installation, the motherboard 2 is first inserted at an angle into the frame 1, with one end positioned between the upper positioning block 11 and the support frame, aligning the limiting protrusion 12 with the assembly slot. Then, the motherboard 2 is pressed down, and the elastic locking block 13 retracts under the pressure of the motherboard 2 until the motherboard 2 is pushed below the elastic locking block 13. The elastic locking block 13 then pops out under the elastic force, blocking the top of the motherboard 2, thus installing the motherboard 2 in place. During this process, the limiting protrusion 12 cooperates with the assembly slot, and one end of the motherboard 2 also extends into the gap between the upper positioning block 11 and the support frame. The assembly operation is simple, and the assembly is firm and compact. When it is necessary to disassemble the motherboard 2, the elastic locking block 13 is retracted using tools or manually, and the motherboard 2 is tilted and pulled out. To improve the installation stability of the motherboard 2, in some embodiments, there are two upper positioning blocks 11, two limiting protrusions 12, and two elastic locking blocks 13, which are symmetrically arranged within the frame 1.

[0027] like Figure 4As shown, in some embodiments, the support frame includes a vertical support bar 15 arranged along the length of the frame 1 and a horizontal support bar 16 arranged away from the upper positioning block 11 and along the width of the frame 1. The support frame supports the motherboard 2, reducing or preventing pressure between the motherboard 2 and components such as the display mounted on the frame 1, thus preventing damage to these components. The vertical support bar 15 and the horizontal support bar 16 increase the contact area between the support frame and the motherboard 2, improving installation stability.

[0028] To further enhance the stability of the support bracket for motherboard 2 and improve assembly strength, such as Figure 4 As shown, in some embodiments, the support frame further includes a central support strip 17 disposed along the width direction of the frame 1, the central support strip 17 being located between the transverse support strip 16 and the upper positioning block 11. The central support strip 17 provides support for the center of the motherboard 2, improving the stability of the support frame for the motherboard 2.

[0029] like Figure 4 As shown, to prevent the motherboard 2 from directly contacting the main body of the frame 1 during installation or disassembly and causing damage to the frame 1, in some embodiments, a baffle 18 is also provided at one end of the vertical support bar 15 near the upper positioning block 11. The baffle 18 extends from the support frame to the upper positioning block 11. During assembly, one end of the motherboard 2 will not directly contact the main body of the frame 1 due to the obstruction of the baffle 18.

[0030] like Figure 2 and 4 As shown, in order to facilitate the smooth engagement of the limiting protrusion 12 with the mounting slot on the motherboard 2 during assembly, in some embodiments, the end of the limiting protrusion 12 away from the support frame is provided with an inclined guide surface 121. As the motherboard 2 is inserted into the frame 1 at an angle during assembly, the guide surface 121 reduces the width of the limiting protrusion 12 protruding from the side wall of the frame 1 at the end away from the support frame, allowing the mounting slot of the motherboard 2 to smoothly engage with the limiting protrusion 12 when the motherboard 2 is pressed for assembly. Furthermore, it also allows the motherboard 2 to automatically center itself along the inclined surface during assembly.

[0031] like Figure 2 , 4As shown in Figure 5, to facilitate the popping and retraction of the elastic latch 13, in some embodiments, a receiving hole 14 for accommodating the elastic latch 13 is provided on the side wall of the frame 1. One end of the elastic latch 13 is fixedly connected to the top of the receiving hole 14. In the popped-out state, the elastic latch 13 protrudes from the receiving hole 14 and is in an inclined state. When the elastic latch 13 retracts under the pressure of the motherboard 2 or the action of external force, it can retract into the receiving hole 14 on the side wall of the frame 1, making it easier for the motherboard 2 to be pressed down or removed. The inclined state of the elastic latch 13 when popped out can guide the assembly of the motherboard 2, facilitating assembly.

[0032] like Figures 2-5 As shown, in some embodiments, the end face of the elastic block 13 near the support frame is an inclined guide surface 131, and the main board 2 is engaged between the guide surface 131 and the support frame. After the main board 2 is pressed into place, it can automatically slide down along the inclined guide surface 131 between the guide surface 131 and the support frame, thus playing a guiding role.

[0033] In some embodiments, the gap between the bottom edge of the guide surface 131 and the support frame is smaller than the thickness of the motherboard 2. For example... Figure 3 As shown, this setting allows the motherboard 2 to be secured on the inclined guide surface 131 after assembly. At this time, the elastic block 13 still maintains a certain elasticity. The inclined guide surface 131 can relatively squeeze the motherboard 2, simultaneously squeezing and limiting the motherboard 2 in both the thickness and width directions, thereby improving the stability and firmness of the motherboard 2 assembly.

[0034] like Figure 2 and 4 As shown, in order to improve the strength of the upper positioning block 11, in some embodiments, the upper positioning block 11 is provided with reinforcing ribs 111.

[0035] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this application.
