Description

Technical Field

[0001] This utility model particularly relates to a button-type bracket. Background Technology

[0002] In television (TV) manufacturing, LCD glass typically needs to be fitted with a source PCB (driver circuit board), and each TV must ensure the secure mounting of this PCB. Currently, the industry generally uses a mechanical mounting solution, which achieves installation through PCB mounting brackets. However, existing technology has the following prominent problems:

[0003] 1. The mold has a complex structure and high cost.

[0004] Existing PCB mounting brackets typically employ a design with a snap-fit ​​structure. Their molds require complex structures such as angled ejectors or sliders to form the barb features, resulting in high mold costs, complex mold processing difficulties, high maintenance costs, low production efficiency, long demolding cycles, and yield rates significantly affected by mold precision.

[0005] 2. Difficult to install and poor reliability

[0006] Typical structures of existing stents (e.g.) Figure 6-7 The device (as shown) includes: a support base with spaced-out positioning posts (1-1) and fixing seats; the fixing seats have slots (1-3) for engaging elastic pieces (1-2) on the PCB board, and the positioning holes on the PCB board cooperate with the positioning posts (1-1) to achieve secondary fixation. During installation, the elastic pieces (1-2) on the PCB board are squeezed to deform them and then inserted into the slots (1-3); the PCB board is pressed down so that the positioning posts (1-1) pass through the positioning holes. The elastic pieces (1-2) are prone to fatigue and loosening after long-term use, leading to loosening of the PCB board; multiple alignments and force applications are required, making installation cumbersome and difficult. Utility Model Content

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a button-type bracket.

[0008] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0009] A button-type bracket includes:

[0010] Scaffold matrix;

[0011] A button positioning component is disposed on the bracket base and is used to engage and fix with the positioning hole of the circuit board;

[0012] A rotary guide mechanism is disposed on the bracket base at a distance from the button positioning component;

[0013] The constraint part is disposed between the button positioning member and the rotary guide mechanism;

[0014] The circuit board is pivoted to contact and limit the constraint part through a rotary guide mechanism, and the button positioning part is fixed by engaging with the positioning hole through axial displacement.

[0015] Preferably, the button positioning component includes a pair of elastically deformable positioning arms, which are symmetrically arranged on the support base and form a tapered guide structure. During the installation of the circuit board, the positioning arms are squeezed by the sidewall of the positioning hole to produce opposite elastic deformation. After completely passing through the positioning hole, the positioning arms expand radially to form a locking and fixing with the inner wall of the positioning hole.

[0016] Preferably, each positioning arm includes a connector connected to the support base. The end of the connector is provided with a guide portion. During assembly, the two guide portions are deformed by the sidewall of the positioning hole and move closer to each other. After completely passing through the positioning hole, the two guide portions restore their deformation to engage the positioning hole of the circuit board with the connector.

[0017] Preferably, the constraint part includes a pair of parallel limiting guide rails, and a limiting opening is formed on the circuit board. The circuit board generates a pivoting motion under the guidance of the rotary guide mechanism, so that the side wall of the limiting opening and the limiting guide rail form a surface contact limiting fit, so that the axial pressing motion of the button positioning member forms an elastic snap-lock fixation with the positioning hole of the circuit board.

[0018] Preferably, the rotary guide mechanism includes a hook portion disposed on the support base and a notch portion disposed on the hook portion. When the circuit board pivots, the notch portion cooperates with the pair of limiting guide rails to jointly constrain the rotation path of the sidewall of the limiting opening.

[0019] Preferably, the connector and the guide are integrally formed.

[0020] The beneficial effects of this utility model are:

[0021] The button-type bracket of this application uses a combination of a button positioning component, a rotary guide mechanism, and a constraint part. The button positioning component locks the circuit board in place, while the constraint part limits and fixes the circuit board by limiting the opening, effectively preventing the circuit board from coming loose. In addition, during installation, you only need to place the side wall of the limiting opening of the circuit board into the notch and then manually rotate the circuit board. When the circuit board pivots under the guidance of the rotary guide mechanism, the side wall of the limiting opening forms a surface contact limiting fit with the limiting guide rail. The button positioning component can lock and fix itself with the positioning hole through axial displacement, making installation very convenient and labor-saving. Attached Figure Description

[0035] A button-type bracket, as shown Figures 1-5 This includes:

[0036] Scaffold substrate 1;

[0037] A button positioning component is disposed on the bracket base 1 and is used to engage and fix with the positioning hole 51 of the circuit board 5;

[0038] The rotary guide mechanism 3 is disposed on the bracket base 1 at a distance from the button positioning component;

[0039] The constraint part 4 is disposed between the button positioning member and the rotary guide mechanism 3;

[0040] The circuit board 5 is pivoted to contact and limit the constraint part 4 via the rotary guide mechanism 3, and the button positioning part is engaged and fixed with the positioning hole 51 by axial displacement.

[0041] Furthermore, the button positioning component includes a pair of elastically deformable positioning arms 21, which are symmetrically arranged on the bracket base 1 and form a tapered guide structure. During the installation of the circuit board 5, the positioning arms 21 are squeezed by the side wall of the positioning hole 51 and undergo opposing elastic deformation. After completely passing through the positioning hole 51, the positioning arms 21 expand radially to form a locking and fixing with the inner wall of the positioning hole 51.

[0042] Furthermore, each positioning arm 21 includes a connector 211 connected to the support base 1. The end of the connector 211 is provided with a guide portion 212. During assembly, the two guide portions 212 are deformed by the side wall of the positioning hole 51 and move closer to each other. After completely passing through the positioning hole 51, the two guide portions 212 restore their deformation to engage the positioning hole 51 of the circuit board 5 with the connector 211.

[0043] Furthermore, the constraint part 4 includes a pair of parallel limiting guide rails 41, and the circuit board 5 has a limiting opening 52. The circuit board 5 generates a pivoting motion through the guidance of the rotary guide mechanism 3, so that the side wall of the limiting opening 52 and the limiting guide rail 41 form a surface contact limiting fit, so that the axial pressing motion of the button positioning member forms an elastic snap-lock fixation with the positioning hole 51 of the circuit board 5.

[0044] Furthermore, the rotary guide mechanism 3 includes a hook 31 disposed on the support base 1 and a notch 311 disposed on the hook 31. When the circuit board 5 pivots, the notch 311 spatially engages with the pair of limiting guide rails 41 to jointly constrain the rotation path of the sidewall of the limiting opening 52.

[0045] Furthermore, the connector 211 and the guide portion 212 are integrally formed.

[0046] The working principle of this utility model is as follows:

[0047] like Figure 1 As shown, the button-type bracket of the present invention mainly includes a bracket base 1, a button positioning component, a rotating guide mechanism 3, and a constraint part 4.

[0048] The support base 1 serves as the basic structure of the entire support, used to support other components and install and fix them on the corresponding equipment housing or other support structures.

[0049] The button positioning component is mounted on the bracket base 1, and its specific structure is as follows: Figure 1 As shown, it includes a pair of elastically deformable positioning arms 21. These two positioning arms 21 are symmetrically spaced on the support base 1 and form a tapered guide structure. As an embodiment 1, this application illustrates the design concept by taking an example where the positioning arm 21 consists of a connector 211 connected to the support base 1 and a guide portion 212 located at the end of the connector 211. The connector 211 and the guide portion 212 are integrally formed, ensuring the stability and reliability of the structure, while also simplifying the production process and reducing production costs. During the installation of the circuit board 5, as... Figure 2-4 As shown, the two guide parts 212 are pressed together by the side wall of the positioning hole 51 so that the two guide parts 212 can pass through the positioning hole 51; when the two guide parts 212 have completely passed through the positioning hole 51, the guide parts 212 lose the pressing effect of the positioning hole 51 and move away from each other, thereby realizing the engagement and fixation of the positioning hole 51 and the button positioning part.

[0050] The rotary guide mechanism 3 is spaced apart from the button positioning component on the support base 1. Its structure includes a hook 31 on the support base 1 and a notch 311 on the hook 31. During the installation of the circuit board 5, the rotary guide mechanism 3 guides the circuit board 5 to pivot, allowing it to rotate along a predetermined path and angle to cooperate with the constraint part 4 for limiting engagement. Figure 2-4 As shown.

[0051] The constraint part 4 is disposed between the button positioning member and the rotary guide mechanism 3, specifically including a pair of parallel limiting guide rails 41. A limiting opening 52 is formed on the circuit board 5; when the circuit board 5 is manually rotated, and the circuit board 5 pivots under the guidance of the rotary guide mechanism 3, the sidewall of the limiting opening 52 forms a surface contact limiting fit with the limiting guide rails 41 (e.g., ...). Figure 2-3 As shown in the diagram, this restricts the rotation angle and position of the circuit board 5, preventing excessive rotation or free wobbling. Simultaneously, this surface contact mating method evenly distributes the pressure between the circuit board 5 and the support base 1, avoiding localized stress concentration and improving the stability and reliability of the fixation. After the circuit board 5 is limited by the constraint part 4, the button positioning component further tightens the positioning arm 21 against the inner wall of the positioning hole 51 through axial pressing movement, forming an elastic snap-fit ​​fixation, thus completing the entire installation process of the circuit board 5. Figure 4 As shown.

[0052] When disassembling circuit board 5, simply lift one end of circuit board 5 gently to overcome the force between button positioning part 2 and positioning hole 51 and the limiting effect of constraint part 4, so that circuit board 5 can pivot in the opposite direction around rotation guide mechanism 3, and circuit board 5 can be easily removed from bracket base 1. The whole process does not require any tools, and the operation is simple and quick, which greatly improves the efficiency of electronic equipment production, assembly and maintenance replacement.

[0053] The button-type bracket of this invention uses a combination of a button positioning component, a rotary guide mechanism, and a constraint part. The button positioning component locks the circuit board in place, while the constraint part limits and fixes the circuit board by limiting the opening, effectively preventing the circuit board from coming loose. In addition, during installation, you only need to place the side wall of the limiting opening of the circuit board into the notch and then manually rotate the circuit board. When the circuit board pivots under the guidance of the rotary guide mechanism, the side wall of the limiting opening forms a surface contact limiting fit with the limiting guide rail. The button positioning component can lock and fix itself with the positioning hole through axial displacement, making installation very convenient and labor-saving.
