Description

Technical Field

[0001] The utility model relates to the field of COB modules, in particular to a shell installation structure of a COB module. Background Art

[0002] The COB (Chip on Board) module is a technical method of directly mounting chips on circuit boards. It is widely used in various electronic devices. In the COB module, electronic components are placed on the surface of the PCB (printed circuit board) and soldered to achieve electrical connection. With the continuous advancement of technology and changes in market demand, COB module technology is also constantly developing.

[0003] However, the traditional COB module housing installation structure only reserves hidden locations for the conductive line routing when in use. However, the conductive lines may bend at certain wiring harness stacking locations. The current housing installation structure lacks a wire harness restraint structure, which can easily affect the stability of the COB module and housing assembly process.

[0004] For example, when some excessively long conductive wires gather together, they are prone to bending and supporting. If the module is installed solely by the adsorption force between the module and the housing, the bent conductive wires may support the back of the module, affecting the alignment of the module and the housing when the COB module is installed. Utility Model Content

[0005] The utility model discloses a shell mounting structure for a COB module, which aims to solve the technical problem that, when in use, the shell mounting structure of the traditional COB module mostly only reserves a hidden position for routing the conductive line, but the conductive line will bend at some wire harness stacking positions, and the current shell mounting structure lacks a wire harness limiting structure, which easily affects the stability of the COB module and shell assembly process.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A shell mounting structure for a COB module includes a shell box body and a COB module body arranged on the shell box body, a PCB board is provided at a central position inside the shell box body, and also includes: a rebound limiting mechanism: the rebound limiting mechanism includes a plurality of slides arranged inside the shell box body, a slider is slidably connected to the inner wall of the slide, a telescopic rod is installed on the top of the slider, a connecting block is installed on the top of the telescopic rod, a limiting buckle plate is connected to the connecting block through a bearing, a return spring is provided on the outer wall of the piston rod of the telescopic rod, the top of the return spring is connected to the connecting block, and the bottom end of the return spring is connected to the fixed end of the telescopic rod; a threading mechanism: the threading mechanism is arranged on one side of the slide.

[0008] In this solution, the converged wiring harness can be restricted by the rebound limit mechanism. Under the pulling action of the reset spring, the limiting plate presses the converged wiring harness downward to prevent the wiring harness from bending and arching. In this way, after the outer shell box is installed, the COB module body can be stably aligned with the outer shell box, and the installation process is more efficient and stable.

[0009] In a preferred solution, the threading mechanism includes a first side through hole and a second side through hole provided on the outer wall of the outer shell box body, and the first side through hole and the second side through hole both correspond to the connection points on the PCB board.

[0010] By setting up a threading mechanism, the wiring harness can be guided inside the outer shell box to avoid the wiring harness crossing inside the outer shell box. At the same time, the threading mechanism is close to the slide in the rebound limit mechanism, so the wiring harness can be limited in a dispersed manner nearby, and the wiring control is reasonable and orderly.

[0011] As can be seen from the above, a shell mounting structure of a COB module includes a shell box body and a COB module body arranged on the shell box body, a PCB board is provided at the central position inside the shell box body, and further includes: a rebound limiting mechanism: the rebound limiting mechanism includes a plurality of slideways provided inside the shell box body, a slider is slidably connected to the inner wall of the slideway, a telescopic rod is installed on the top of the slider, a connecting block is installed on the top of the telescopic rod, a limiting buckle plate is connected to the connecting block through a bearing, a return spring is provided on the outer wall of the piston rod of the telescopic rod, the top end of the return spring is connected to the connecting block, and the bottom end of the return spring is connected to the fixed end of the telescopic rod; a threading mechanism: the threading mechanism is provided on one side of the slideway. The shell mounting structure of the COB module provided by the utility model has the technical effect of controlling the internal wiring in a stable and orderly manner and improving the installation stability.

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0018] The shell mounting structure of a COB module disclosed in the present invention is mainly used for the shell mounting structure of a traditional COB module. When in use, most of the shell mounting structures only reserve hidden positions for the routing of the conductive lines. However, the conductive lines will bend at certain wiring harness stacking positions, and the current shell mounting structure lacks a wire harness limiting structure, which easily affects the stability of the COB module and shell assembly process.

[0019] Reference Figure 1 、 Figure 2 and Figure 3 A shell mounting structure for a COB module includes a shell box body 1 and a COB module body 2 arranged on the shell box body 1. A PCB board 7 is provided at the central position inside the shell box body 1. The shell box body 1 also includes: a rebound limiting mechanism: the rebound limiting mechanism includes a plurality of slideways 8 provided inside the shell box body 1, a slider 9 is slidably connected to the inner wall of the slideway 8, a telescopic rod 10 is installed on the top of the slider 9, a connecting block is installed on the top of the telescopic rod 10, a limiting buckle plate 12 is connected to the connecting block through a bearing, a return spring 11 is provided on the outer wall of the piston rod of the telescopic rod 10, the top end of the return spring 11 is connected to the connecting block, and the bottom end of the return spring 11 is connected to the fixed end of the telescopic rod 10;

[0020] Threading mechanism: The threading mechanism is arranged on one side of the slideway 8.

[0021] Specifically, the converged wire harness can be limited by the rebound limit mechanism. Under the pulling action of the reset spring 11, the limiting buckle plate 12 presses the converged wire harness downward to prevent the wire harness from bending and arching. In this way, after the outer shell box body 1 is installed, the COB module body 2 can stably correspond to the outer shell box body 1.

[0022] It should be noted that the limiting buckle plate 12 is movably connected to the connecting block and can be rotated and adjusted. During the process of connecting the wiring harness, the limiting buckle plate 12 can be rotated to an area that does not affect the threading mechanism. After the threading is completed, it can be rotated back to limit the threaded wiring harness. The adjustment is flexible and convenient.

[0023] The PCB board 7 is connected to a power supply and a control chip.

[0024] Among them, several slideways 8 are located around the PCB board 7, which can effectively disperse the wiring.

[0025] Reference Figure 1 and Figure 3 In a preferred embodiment, the threading mechanism includes a first side through hole 3 and a second side through hole 4 provided on the outer wall around the outer shell box body 1, and the first side through hole 3 and the second side through hole 4 both correspond to the connection points on the PCB board 7.

[0026] Specifically, through the provided threading mechanism, the routing of the wiring harness can be guided inside the outer shell box body 1 to avoid the wiring harness crossing inside the outer shell box body 1. At the same time, the threading mechanism is close to the slide 8 in the rebound limit mechanism, so the wiring harness can be limited in a dispersed manner nearby, and the routing control is reasonable and orderly.

[0027] Reference Figure 2 and Figure 4 In a preferred embodiment, first mounting holes 13 are provided at the four corners of the bottom outer wall of the outer shell body 1, and second mounting holes are provided on the four inner walls of the outer shell body 1.

[0028] Specifically, two adjacent outer shell boxes 1 can be connected by using screws in conjunction with the second mounting holes, and the outer shell box 1 can be fixed to a designated wall by using screws in conjunction with the first mounting holes 13. Both together maintain the stability of the outer shell mounting structure of the COB module during the specific assembly process.

[0029] Reference Figure 2 and Figure 3 In a preferred embodiment, a plurality of magnetic columns 6 are provided at the bottom of the outer shell body 1, and a magnetic connector corresponding to the magnetic columns 6 is provided on the COB module body 2. Fixed grooves are provided at the four corners of the outer wall of the top of the outer shell body 1, and a filling pad 5 is provided on the inner wall of the fixing groove. The filling pad 5 is made of soft rubber material.

[0030] Specifically, the installation height of the filling pad 5 in the fixing groove is slightly higher than the depth of the fixing groove. During the assembly process of the COB module body 2 and the outer shell box body 1, the filling pads 5 at the four corners can play a flexible supporting role, thereby avoiding wear between the COB module body 2 and the outer shell box body 1 to a certain extent.

[0031] It should be noted that the COB module body 2 packaging technology in this solution adopts a high fill factor optical design, which can effectively eliminate moiré patterns.

[0032] Working principle: When in use, first install the outer shell box body 1 to the designated wall area, and then use screws to match the first mounting holes 13 to fix the box body to the designated wall. During the installation process, use screws to match the second mounting holes to connect two adjacent outer shell box bodies 1, keeping the overall connection between the outer shell box bodies 1 stable. After the outer shell box body 1 is installed, install the COB module body 2 to the corresponding outer shell box body 1.

[0033] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
