Description

Technical Field

[0001] This utility model relates to the field of electronic component installation technology, and in particular to a shock-absorbing rubber ring Bluetooth module anti-drop fixing bracket. Background Technology

[0002] Bluetooth technology, as a mature short-range wireless communication standard, has been widely used in smartphones, laptops, IoT devices, wearable devices, industrial sensors, and various portable electronic products. The Bluetooth module, as the core component enabling this function, integrates radio frequency chips, baseband processors, crystal oscillators, and passive components, making its structure both precise and fragile. In practical applications, especially in portable and outdoor devices, Bluetooth modules inevitably face the risk of mechanical shock from accidental drops, everyday impacts, or continuous vibrations from the operating environment. These physical stresses are one of the main causes of Bluetooth module malfunction or physical damage, specifically manifesting as chip desoldering, BGA solder ball cracking, ceramic capacitor breakage, crystal oscillator performance drift, and even PCB circuit breakage.

[0003] In existing technologies, the installation and protection methods for Bluetooth modules can be mainly divided into the following categories: The first category is the most common direct soldering or connector installation method. This involves directly soldering the Bluetooth module onto the motherboard or fixing it using standard board-to-board connectors or pin headers. This method is compact and low-cost, but the module forms a rigid connection with the motherboard, offering almost no cushioning capability. When the device is subjected to impact or vibration, all mechanical stress is directly transmitted to the module's interior through the solder joints or connector pins, posing a direct threat to delicate electronic components. The second category involves adding simple elastic pads or foam between the module and the housing. This method can isolate high-frequency, low-amplitude vibrations to some extent, but its cushioning effect is very limited against the high acceleration and large displacement impacts generated when the device is dropped. Ordinary foam materials are prone to plastic deformation, and their elasticity decreases significantly after several impacts, leading to a decline in cushioning performance and failing to provide continuous and reliable protection. Furthermore, these materials may release chemicals after aging, posing a potential corrosion risk to the module's circuitry.

[0004] There is an urgent need in this field for a compact, cost-effective, and highly protective drop-resistant mounting bracket for Bluetooth modules. It should provide a multi-stage, efficient shock energy absorption mechanism to minimize the dynamic stress experienced by the module in drop and vibration environments, while ensuring stable installation, easy assembly and disassembly, and a certain degree of environmental adaptability, thereby significantly improving the durability and reliability of electronic products with integrated Bluetooth functionality. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing rubber ring Bluetooth module anti-drop fixing bracket to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A shock-absorbing rubber ring Bluetooth module anti-drop fixing bracket includes a Bluetooth module and a protective shell. The top of the protective shell is provided with a clearance groove for avoiding the data transmission link of the Bluetooth module. The protective shell includes a housing, an end cap, and a filling layer. The end cap is snapped and fixed to the top of the housing. The top of the housing is completely open. The clearance groove is opened at the center of the top of the end cap and runs through the top and bottom. The filling layer is used to fix the Bluetooth module inside the housing. A rubber layer is adhered to the bottom of the end cap, and the rubber layer is a hollow structure with an internal hollow structure.

[0007] By adopting the above technical solution, the filling layer needs to have a certain degree of flexibility. The Bluetooth module is installed on the top of the filling layer, and then the top periphery of the Bluetooth module is pressed against the bottom of the rubber layer by the filling layer. When vibration occurs, the rubber layer and the buffer layer absorb most of the kinetic energy, so that a small part of the kinetic energy is transferred to the Bluetooth module, which plays a protective role for the Bluetooth module. In most scenarios, the Bluetooth module will not be damaged due to falling from a height.

[0008] In a further embodiment, the filling layer is a hollow multi-layer structure, and the filling layer consists of a wear-resistant layer, an insulating layer, an airtight layer, and a puncture-resistant layer from the inside out.

[0009] By adopting the above technical solutions, the wear-resistant layer is used to prevent the filling layer from rubbing against the inner wall of the shell when the filling layer is deformed as a whole, thus extending the service life of the filling layer; the insulating layer is used for insulation protection; the airtight layer is used to prevent the gas filled inside the filling layer from leaking out quickly; and the puncture-proof layer is used for final protection.

[0010] In a further embodiment, the top of the filling layer is provided with a vertically penetrating channel, and the channel does not affect the overall airtightness of the filling layer.

[0011] By adopting the above technical solution, the channel is used to avoid the wire harness passing through, so that the wire harness can be passed out from the bottom of the housing, making it easier to install.

[0012] In a further embodiment, the top periphery of the Bluetooth module is uniformly provided with a plurality of protruding cylinders, each cylinder being fitted with a spring, and the bottom of the end cap is provided with a circular hole corresponding to the cylinder, the diameter of the circular hole being larger than the diameter of the cylinder, and the top of the spring being located inside the circular hole.

[0013] By adopting the above technical solution, a section of cylinder also needs to be located inside the circular hole. This setting is to prevent the Bluetooth module from moving excessively and to confine it to a certain space during buffering and shock absorption.

[0014] In a further embodiment, the end cap is snap-fitted onto the top of the housing, and the mating surface between the end cap and the housing is filled with structural adhesive.

[0015] The above technical solution is used for disassembly and repair.

[0016] In a further embodiment, the outer diameter of the spring is transition-fitted with the diameter of the circular hole, and the inner diameter of the spring is interference-fitted with the diameter of the cylinder.

[0017] In summary, this utility model has the following beneficial effects: 1. The filling layer needs to have a certain degree of flexibility. The Bluetooth module is installed on the top of the filling layer, and then the top periphery of the Bluetooth module is pressed against the bottom of the rubber layer through the filling layer. When vibration occurs, the rubber layer and the buffer layer absorb most of the kinetic energy, so that a small part of the kinetic energy is transferred to the Bluetooth module, which plays a protective role for the Bluetooth module. In most scenarios, the Bluetooth module will not be damaged due to falling from a height. Attached Figure Description
