Description

Technical Field

[0001] This utility model relates to the field of electronic device technology, and in particular to a folding hinge structure for a tablet holder. Background Technology

[0002] Existing tablet stands generally suffer from limited functionality and poor adaptability. Specifically, most stands have a fixed, non-adjustable support angle, failing to meet diverse viewing needs. Even those that do offer angle adjustment often lack effective self-locking mechanisms, causing the stand to spring back or loosen under stress, resulting in poor stability. Furthermore, the width of the stands is usually fixed, making them unsuitable for tablets of different sizes or devices with protective cases, thus limiting their versatility. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the fixed and non-adjustable support angle of most stands, which cannot meet the diverse viewing needs of users; even if some products support angle adjustment, they lack an effective self-locking mechanism, causing the stand to easily spring back or loosen after being subjected to force, resulting in poor stability. In addition, the width of the stand is usually fixed, which cannot be adapted to tablets of different sizes or devices with protective cases, resulting in poor versatility. Therefore, this invention proposes a folding hinge structure for a tablet stand.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A folding hinge structure for a flat panel bracket includes: a first bracket and a second bracket, both the first bracket and the second bracket being provided with connecting plates, and the connecting plates being provided with limiting components;

[0006] The limiting component includes a ratchet rotatably disposed within the connecting plate, a pawl rotatably disposed within the connecting plate, and an elastic reset component connected to the pawl.

[0007] As a preferred embodiment of the folding pivot structure of the flat plate bracket described in this utility model, the two sets of connecting plates are respectively provided with a first placement frame and a second placement frame, and one end of the first placement frame is provided with a slide rod that is inserted into the second placement frame.

[0008] In a preferred embodiment of the folding pivot structure of the flat plate bracket described in this utility model, the second bracket is provided with an adjustment component for adjusting the lateral length.

[0009] In a preferred embodiment of the folding pivot structure of the flat plate bracket of this utility model, the adjusting component includes a first connecting rod fixedly mounted on the first bracket, a second connecting rod mounted on the second bracket, an adjusting rod fixedly mounted at one end of the first connecting rod, a connecting spring mounted inside the adjusting rod, and a locking block mounted on the connecting spring.

[0010] As a preferred embodiment of the folding pivot structure of the flat plate bracket of this utility model, the second connecting rod is provided with a circular groove for use with the locking block, and the adjusting component is used in conjunction with the first placement frame and the second placement frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By employing a limiting component consisting of a ratchet, pawl, and elastic reset element, the bracket can be reliably locked at any angle during the unfolding process, effectively preventing rebound and loosening caused by equipment weight or contact, providing stable support, and greatly enhancing the user experience and sense of security.

[0013] By sliding the first and second mounting brackets together and designing an adjustment component consisting of a spring-loaded locking mechanism, the lateral support length of the stand can be easily adjusted in multiple levels, thus perfectly adapting to tablets and even laptops of different sizes and expanding the application scenarios of the product.

Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Reference Figures 1-3 A folding pivot structure for a flat plate bracket includes a first bracket 101 and a second bracket 102. Both the first bracket 101 and the second bracket 102 are provided with connecting plates 103. Considering the stability of the bracket after it is unfolded and to prevent the bracket from springing back after adjustment, a limiting component 106 is provided on the connecting plate 103. The limiting component 106 includes a ratchet 1061 rotatably disposed in the connecting plate 103, a pawl 1062 rotatably disposed in the connecting plate 103, and an elastic reset component 1063 connected to the pawl 1062.

[0022] Reference Figure 1 and Figure 4 Considering the different sizes of the flat plates, adjustments are required according to different sizes. Therefore, two sets of connecting plates 103 are respectively equipped with a first placement frame 104 and a second placement frame 105. One end of the first placement frame 104 is equipped with a sliding rod that inserts into the second placement frame 105. At the same time, the second support 102 is equipped with an adjustment component 107 for adjusting the horizontal length. The adjustment component 107 includes a first connecting rod 1071 fixedly mounted on the first support 101 and a second connecting rod 1072 mounted on the second support 102. One end of the first connecting rod 1071 is fixedly equipped with an adjustment rod 1073. A connecting spring 1074 is installed inside the adjustment rod 1073. A locking block 1075 is installed on the connecting spring 1074. A circular groove for matching the locking block 1075 is opened on the second connecting rod 1072. The adjustment component 107 is used in conjunction with the first placement frame 104 and the second placement frame 105.

[0023] In addition, anti-slip pads are provided at both the upper and lower ends of the first support 101 and the second support 102, and anti-slip pads are also provided at the lower part of the first placement rack 104 and the second placement rack 105 that contact the table.

[0024] In summary, the working process of this solution is as follows:

[0025] When the user needs to unfold the bracket, press the pawl 1062 to disengage it from the ratchet 1061, then rotate the first placement bracket 104 and the second placement bracket 105. After adjustment, release the pawl 1062, and it can stay at any angle to achieve self-locking. When folding is required, simply reverse the operation. When it is necessary to adjust the lateral length of the bracket to accommodate a wider device, press the locking block 1075, then pull the first bracket 101 and the second bracket 102. At this time, the first placement bracket 104 and the second placement bracket 105 move accordingly. When the appropriate width is reached, the locking block 1075 springs into the new circular groove under the action of the connecting spring 1074, completing the length locking.

[0026] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0027] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
