Description

Technical Field

[0001] This application relates to the field of Bluetooth module testing technology, and more specifically, to a Bluetooth module testing fixture. Background Technology

[0002] With the rapid development of wireless communication technology, Bluetooth modules, as a short-range wireless communication technology, have been widely used in consumer electronics products such as smartphones, tablets, wireless headphones, and automotive systems, as well as in fields such as industrial control and medical equipment. The performance and quality of Bluetooth modules directly affect the user experience and reliability of end products; therefore, rigorous testing of Bluetooth modules is essential.

[0003] Currently, structural strength testing is an essential step in the production and quality inspection of Bluetooth modules, primarily used to evaluate the module's reliability and stability under harsh environments such as vibration and impact. This test typically simulates vibration conditions in real-world usage environments to verify the Bluetooth module's shock resistance. Several tooling devices exist on the market for Bluetooth module testing, which can meet basic testing requirements to a certain extent. However, existing Bluetooth module testing tooling generally suffers from a problem when performing structural strength tests, especially vibration tests: due to the need to simulate a vibration environment, the constant collisions between the bottom of the device and the tabletop reduce the device's lifespan and generate significant noise. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a Bluetooth module testing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A Bluetooth module testing fixture includes a base and four fixing blocks integrally formed on both sides of the base. The fixture is characterized by: a plurality of vibration springs fixedly installed at equal intervals on the surface of the base; a top plate installed on top of the vibration springs; a vibration motor installed at the bottom of the top plate; connecting components at the four corners opposite to the top plate; a protective frame bolted to the surface of the top plate; and a Bluetooth module limiting component installed on the protective frame, with the positioning end of the Bluetooth module limiting component pointing perpendicularly to the surface of the top plate.

[0007] Furthermore, the bottom of the top plate is integrally formed with several sleeves, and the interior of each of the sleeves is respectively connected to the top of a number of vibration springs.

[0008] Furthermore, the connecting component includes four sets of threaded heads, four sets of nuts, four sets of connecting cylinders, and four ropes. The four sets of threaded heads are integrally formed with the four corners of the opposite ends of the base and the top plate, respectively. The four sets of nuts are threadedly connected to the four sets of threaded heads, and their opposite ends are integrally formed with the outer ends of the four sets of connecting cylinders. The two ends of the four ropes are respectively connected to the internal knots of the four sets of connecting cylinders.

[0009] Furthermore, the protective frame has windows on its surface and connecting plates at both ends, which are fixedly connected to the threaded holes at both ends of the top plate surface by bolts.

[0010] Furthermore, the Bluetooth module limiting component includes four through holes, four straight rods, four cones, four tethering rings, and four compression springs. The protective frame surface is provided with four through holes. The bottom ends of the four straight rods are integrally formed with the top ends of the four cones, and the top ends of the rods pass through the interior of the four through holes. The four tethering rings are respectively installed on the top ends of the four straight rods. The four compression springs are respectively sleeved on the outer walls of the four straight rods, and their two ends are respectively attached to the top of the inner side of the protective frame and the extended rings on the surface of the four cones.

[0011] Furthermore, a gasket is provided on the surface of the top plate, the bottom of the gasket is bonded to the surface of the top plate, and a Bluetooth module is placed on the surface.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model's fixture, through the design of a vibration spring and sleeve, isolates the vibration source (vibration motor) from the base, avoiding direct and violent collisions between the vibrating part and the tabletop. The vibration spring buffers the impact force generated by the vibration motor, allowing vibration energy to be transmitted more smoothly, greatly reducing noise generated by collisions, creating a quiet and comfortable working environment for operators, improving work efficiency, reducing interference with surrounding equipment, and ensuring the smooth operation of the entire production or testing process.

[0014] 2. In this utility model, several sleeves integrally formed at the bottom of the top plate are connected to the top of the vibration spring. This design not only makes the connection between the vibration spring and the top plate more stable, but also ensures that the vibration generated by the vibration motor can be efficiently and stably transmitted to the top plate through the vibration spring, and then evenly applied to the Bluetooth module placed on the top plate. Compared with the potential problem of unstable vibration transmission in the prior art, the testing fixture of this application ensures the accuracy and consistency of vibration testing. In addition, the connecting components set at the four corners of the opposite ends of the base and the top plate adopt a combination structure of threaded head, nut, connecting sleeve and rope, which has unique advantages. On the one hand, the connecting components can limit the vibration amplitude of the top plate to a certain extent, preventing the top plate from violently colliding or detaching from the base due to excessive vibration, ensuring the safety of the testing process, and avoiding personal injury and property damage caused by equipment damage or accidents. On the other hand, it provides a certain degree of elastic support for the top plate, making the vibration process more stable, reducing the impact of vibration instability on the test results, and ensuring the accuracy and reliability of the test data.

[0015] 3. This utility model's Bluetooth module positioning component, through the cooperation of four straight rods, a cone head, a traction ring, and a compression spring, can quickly and accurately position the Bluetooth module on the top plate surface, preventing displacement of the Bluetooth module during vibration and ensuring the accuracy and reliability of the detection. The presence of the compression spring also buffers the impact of vibration on the Bluetooth module positioning component to a certain extent, allowing the positioning component to better adapt to the vibration environment, extending its service life, and reducing potential damage to the Bluetooth module caused by positioning instability.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] Example:

[0026] Please see Figure 1 , Figure 2 A Bluetooth module testing fixture includes a base 1 and four fixing blocks 2 integrally formed on both sides of the base 1.

[0027] The base 1 is made of a sturdy material to ensure its stability during vibration testing; at the same time, it facilitates the support of other components.

[0028] Among them, the four fixing blocks 2 are used to fix the entire fixture on the table or other support surface to prevent it from shifting during the test.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6A Bluetooth module testing fixture includes a base 1 with several vibration springs 3 fixedly installed at equal intervals on its surface. A top plate 4 is installed on top of the vibration springs 3, and a vibration motor 5 is installed at the bottom of the top plate 4. Connecting components 6 are provided at the four corners of the opposite ends of the base 1 and the top plate 4. A protective frame 7 is bolted to the surface of the top plate 4, and a Bluetooth module limiting component 8 is installed on the protective frame 7. The positioning end of the Bluetooth module limiting component 8 points vertically to the surface of the top plate 4. Several sleeves 41 are integrally formed at the bottom of the top plate 4. The connecting components 6 include four sets of threaded heads 61, four sets of nuts 62, four sets of connecting cylinders 63, and four ropes 64. A window 71 is opened on the surface of the protective frame 7. The Bluetooth module limiting component 8 includes four through holes 81, four straight rods 82, four cones 83, four traction rings 84, and four compression springs 85. A gasket 9 is provided on the surface of the top plate 4.

[0030] Among them, the selection of vibration spring 3 should take into account its elastic coefficient and load-bearing capacity to ensure that it can effectively absorb the vibration transmitted from the top plate 4 to the base 1, while supporting the top plate 4 and the components on it.

[0031] The top plate 4 is a key component supporting the Bluetooth module and the vibration motor 5. Its design needs to balance strength, rigidity, and reliable connection with the vibration spring 3. The top plate 4 is made of a robust metal material, such as aluminum alloy or steel, and is constructed as a plate structure. Its planar dimensions are determined according to the size of the Bluetooth module and the overall design of the testing fixture, ensuring that it can accommodate the Bluetooth module, the protective frame 7, and related limiting components 8. Several sleeves 41 are integrally formed at the bottom of the top plate 4. The term "integrated" means that the sleeves 41 and the top plate 4 are formed as a whole through processes such as casting, machining, or welding, rather than being connected by threaded connections or adhesives. This integrated design can significantly improve the strength and reliability of the connection, avoiding loosening or detachment during long-term vibration testing. The number and arrangement of the sleeves 41 correspond to the vibration springs 3 on the base 1. For example, if four vibration springs 3 are evenly arranged on the base 1, then four sleeves 41 are also integrally formed at the bottom of the top plate 4, and the arrangement of the sleeves 41 corresponds one-to-one with the top positions of the vibration springs 3. The inner diameter of each sleeve 41 is slightly larger than the outer diameter of the corresponding vibration spring 3, forming a clearance fit. This design ensures that the vibration spring 3 can vibrate freely up and down within the sleeve 41, while avoiding excessive clearance that could reduce vibration transmission efficiency or cause instability. The depth of the sleeve 41 is determined based on the compression of the vibration spring 3 and the overall structural design of the top plate 4, ensuring that the top of the vibration spring 3 remains inside the sleeve 41 even under maximum compression.

[0032] The vibration motor 5 is the source of vibration, and its vibration frequency and amplitude can be adjusted according to the test requirements. Through the vibration isolation effect of the vibration spring 3, the vibration generated by the vibration motor 5 is transmitted to the top plate 4, thereby simulating the vibration conditions in the actual use environment.

[0033] The connecting component 6 is a key component connecting the base 1 and the top plate 4. Its design aims to provide an adjustable and detachable connection to accommodate various needs during vibration testing and prevent the top plate 4 from detaching from the top of the vibration spring 3. Threaded heads 61 are integrally formed at the four opposite corners of the base 1 and the top plate 4, with one threaded head 61 extending upwards or downwards at each corner. The threaded heads 61 have standard threads for threaded connection with nuts 62. The length of the threaded heads 61 is determined according to design requirements to ensure the adjustment range of the connecting component 6. The internal thread of the nut 62 matches the external thread of the threaded head 61. Four sets of nuts 62 are threadedly connected to four sets of threaded heads 61. Rotating the nut 62 adjusts its position on the threaded head 61, thereby adjusting the tension of the rope 64. The connecting cylinder 63 is a hollow cylinder, with its outer ends integrally formed at the opposite ends of the four sets of nuts 62, meaning that a connecting cylinder 63 extends from the bottom of each nut 62. The interior of the connecting tube 63 is used to thread the rope 64 and provides a smooth channel to reduce wear on the rope 64 during vibration. The length and diameter of the connecting tube 63 are determined according to the thickness of the rope 64 and design requirements. The rope 64 is made of a material with a certain degree of elasticity and strength, such as nylon rope or polyester rope, to withstand the tension of the vibration spring 3 and during the vibration test. The two ends of the four ropes 64 are respectively connected to the knots inside the four sets of connecting tubes 63. The knotting method should ensure a firm and reliable connection and be able to withstand a certain amount of tension. The length of the rope 64 is determined according to design requirements to ensure the connection between the sleeve 41 and the vibration spring 3, so that the top plate 4 will not detach during vibration.

[0034] The protective frame 7 is used to protect the Bluetooth module and perform vibration testing, and also facilitates the installation of the Bluetooth module limiting component 8. The protective frame 7 has a window 71 for observing the test status of the Bluetooth module or performing necessary operations; the protective frame 7 is connected to the top plate 4 by bolts through threaded holes, which facilitates the removal and replacement of the protective frame 7.

[0035] The Bluetooth module limiting component 8 is used to fix and position the key components of the Bluetooth module. Its design aims to ensure that the Bluetooth module maintains a stable position during vibration testing, avoiding the impact on test results due to movement or detachment. The protective frame 7 has four through holes 81 for the straight rods 82 to pass through. The bottom ends of the four straight rods 82 are integrally formed with the top ends of the conical heads 83, with the top ends passing through the through holes 81 for easy installation of compression springs 85. The top ends of the four conical heads 83 are integrally formed with the bottom ends of the straight rods 82 and are equipped with extension rings for convenient limiting of the compression springs 85. Four traction rings 84 are respectively installed on the top ends of the four straight rods 82 for fixing or pulling the compression springs 85. The four compression springs 85 are respectively sleeved on the outer walls of the four straight rods 82, with their ends respectively engaging with the inner top of the protective frame 7 and the extension rings on the surface of the conical heads 83. This utilizes the elasticity of the compression springs 85 to position the conical heads 83 of the Bluetooth module. The compression amount of the compression springs 85 can accommodate Bluetooth modules of different sizes and weights, improving the versatility of the limiting component 8. The tip of the cone 83 is oval-shaped and has rubber to prevent damage to the Bluetooth module.

[0036] The gasket 9 is used to protect the bottom of the Bluetooth module and improve stability during vibration testing. The bottom of the gasket 9 has an adhesive layer for secure bonding to the surface of the top plate 4. The adhesive layer typically uses strong adhesive or double-sided tape to ensure that the gasket 9 does not move or detach during vibration testing.

[0037] The working principle of this Bluetooth module testing fixture is as follows: During use, the straight rod 82 is pulled by the pull ring 84, compressing the compression spring 85. The Bluetooth module is placed on the surface of the pad 9, and then the pull ring 84 is released. The elastic force released by the compression spring 85 positions the Bluetooth module with the cone head 83. After the vibration motor 5 is started, its vibration source vibrates the top plate 4. At this time, the vibration spring 3 absorbs the vibration of the top plate 4 without affecting its vibration, simulating the vibration environment in actual use. During operation, the user pulls the pull ring 84 to move the straight rod 82. During this process, the compression spring 85 is compressed and deformed. Then, the Bluetooth module to be tested is placed stably on the surface of the pad 9. After placement, the pull ring 84 is released, releasing the elastic potential energy accumulated in the compression spring 85, pushing the cone head 83 to accurately position and fix the Bluetooth module, ensuring its stability during subsequent testing. Simultaneously, the vibration motor 5 is started; the vibration source generated by the vibration motor 5 acts on the top plate 4, causing it to vibrate. During this process, the vibration spring 3 plays a crucial role in buffering and transmitting vibration energy. It can absorb some of the vibration energy, preventing excessive impact on the overall structure of the tooling, without completely hindering the transmission of vibration to the top plate 4. In this way, the vibration environment that the Bluetooth module may encounter in actual use is effectively simulated, providing conditions that are closer to real-world scenarios for subsequent testing.

[0038] It should be noted that the specific models and specifications of the rope 64 and the vibration motor 5 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The power supply and principle of the vibration motor 5 are clear to those skilled in the art and will not be described in detail here.

[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
