Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio frequency testing, and more specifically, to a Bluetooth conformance testing device. Background Technology
[0002] As a mainstream short-range wireless communication standard, Bluetooth devices undergo rigorous conformance testing before and after mass production to ensure compliance with Bluetooth specifications and good interoperability. Radio frequency (RF) conformance testing is a core component, primarily evaluating key RF performance indicators such as transmit power, receive sensitivity, and frequency offset.
[0003] Currently, mainstream Bluetooth RF conformance testing typically employs a turntable-based dark box test setup. This approach fixes the device under test (DUT) on a rotatable turntable and connects it to a comprehensive test suite via conductive cables. During testing, the turntable rotates the device, and a single coupled antenna fixed to the dark box wall receives or transmits signals to simulate RF performance in different spatial directions. However, this traditional method relies on a mechanical turntable, increasing system complexity and cost, and the time-consuming mechanical rotation process reduces testing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a Bluetooth conformance testing device with a simple structure, which can reduce costs, simplify testing operations, and improve testing efficiency.
[0005] A Bluetooth conformance testing apparatus includes: a mounting platform; a positioning base disposed on the mounting platform for fixing a product to be tested; a first coupling component disposed on at least one side of the positioning base in a first direction, the first coupling component being configured to move along the first direction; and a second coupling component disposed on at least one side of the positioning base in a second direction, the second coupling component being configured to move along the second direction.
[0006] In the above technical solution, by setting a first coupling component and a second coupling component on the periphery of the positioning seat, a traditional mechanical turntable is replaced, eliminating the need for a rotation mechanism, simplifying the overall structure, and reducing the complexity and manufacturing cost of the device. The first coupling component and the second coupling component can move independently along the first direction and the second direction, respectively, thereby quickly adjusting the test position to meet different test requirements and improve the efficiency of multi-angle testing.
[0007] Furthermore, the first coupling component includes a first coupling plate and a movable seat, the movable seat being slidably connected to the mounting platform, and the first coupling plate being disposed on the surface of the movable seat facing the positioning seat.
[0008] In the above technical solution, the first coupling plate is mounted on the movable seat. The distance between the first coupling plate and the positioning seat can be adjusted by the movable seat to meet the requirements of different test parameters and improve the applicability of the device.
[0009] Furthermore, the installation platform is provided with two first guide grooves, which extend along a first direction. The two ends of the movable seat are provided with first connecting members that pass through the corresponding first guide grooves, and the first connecting members can slide along the first guide grooves.
[0010] In the above technical solution, the cooperation between the double first guide grooves and the connecting parts can ensure that the movable seat moves linearly along the first direction, thereby improving the movement accuracy and stability.
[0011] Furthermore, the second coupling component includes a coupling unit and a movable support, the movable support being slidably connected to the mounting platform, and the coupling unit being connected to the movable support and configured to slide along a third direction.
[0012] In the above technical solution, the movable support can move along the second direction, thereby adjusting the distance between the coupling unit and the positioning seat. The coupling unit can slide along the third direction, expanding the spatial degrees of freedom, realizing three-dimensional adjustment, and improving the flexibility of testing.
[0013] Furthermore, the coupling unit includes a second coupling plate and a rotating seat, the rotating seat being rotatably connected to the movable support, and the second coupling plate being disposed on the rotating seat.
[0014] In the above technical solution, the rotating seat enables the second coupling plate to have an angular rotation function, which can adjust the signal coupling direction and ensure the flexibility and accuracy of the test.
[0015] Furthermore, the movable support is provided with a rotation scale, which is used to indicate the rotation angle of the rotating seat.
[0016] In the above technical solution, the rotating scale is directly mounted on the movable bracket, which makes it convenient for the operator to adjust the angle of the rotating seat, improves the intuitiveness of operation, and reduces the difficulty of debugging.
[0017] Furthermore, the mounting platform is provided with a translation scale near the first coupling component and the second coupling component.
[0018] In the above technical solution, the translation scale allows the operator to intuitively see the positions of the first coupling component and the second coupling component, making it easy to adjust the distance between the two and the positioning seat, and reducing the difficulty of debugging.
[0019] Furthermore, the positioning seat is provided with a positioning groove, the contour of which matches the contour of the product to be tested.
[0020] In the above technical solution, the positioning groove can ensure the stability and consistency of the product during the testing process and ensure the accuracy of the test.
[0021] Compared with existing technologies, the advantages of this invention are: by setting a first coupling component and a second coupling component on the periphery of the positioning seat, a traditional mechanical turntable is replaced, eliminating the need for a rotation mechanism, simplifying the overall structure, and reducing the complexity and manufacturing cost of the device. The first coupling component and the second coupling component can move independently along the first and second directions, respectively, thereby quickly adjusting the test position to meet different test requirements and improve the efficiency of multi-angle testing.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] Please refer to Figures 1 to 3In a preferred embodiment, the Bluetooth conformance testing device of this utility model mainly includes a mounting platform 1, a positioning base 2, a first coupling component 3, and a second coupling component 4. The positioning base 2 is disposed on the mounting platform 1 and is used to fix the product to be tested. The first coupling component 3 is disposed on at least one side of the positioning base 2 in a first direction X, and is configured to be movable along the first direction X. The second coupling component 4 is disposed on at least one side of the positioning base 2 in a second direction Y, and is configured to be movable along the second direction Y.
[0030] For example, the mounting platform 1 is the upper surface of a box, and the positioning seat 2 is fixedly mounted on the mounting platform 1 for positioning the product to be tested. In this embodiment, the product to be tested is a Bluetooth module. There are two first coupling components 3, which are respectively located on both sides of the positioning seat 2 in the first direction X. There is one second coupling component 4, which is located on one side of the positioning seat 2 in the second direction Y. It is understood that in other possible embodiments, the number of first coupling components 3 and second coupling components 4 can be adjusted according to actual testing needs. For example, there can be one or two first coupling components 3, and one or two second coupling components 4, which is not limited here.
[0031] By setting a first coupling component 3 and a second coupling component 4 on the periphery of the positioning seat 2, a traditional mechanical turntable is replaced, eliminating the need for a rotation mechanism, simplifying the overall structure, and reducing the complexity and manufacturing cost of the device. The first coupling component 3 and the second coupling component 4 can move independently along the first direction X and the second direction Y, respectively, thereby quickly adjusting the test position to meet different test requirements and improve the efficiency of multi-angle testing.
[0032] In this embodiment, the first coupling component 3 includes a first coupling plate 31 and a movable seat 32. The movable seat 32 is slidably connected to the mounting platform 1, and the first coupling plate 31 is disposed on the surface of the movable seat 32 facing the positioning seat 2. The first coupling plate 31 is disposed on the movable seat 32, and the distance between the first coupling plate 31 and the positioning seat 2 can be adjusted by the movable seat 32, thereby meeting the requirements of different test parameters and improving the applicability of the device.
[0033] The mounting platform 1 has two first guide grooves 11 extending along a first direction X. The two ends of the movable seat 32 are provided with first connecting members passing through the corresponding first guide grooves 11, and the first connecting members can slide along the first guide grooves 11. For example, the two ends of the movable seat 32 extend horizontally outward to form extensions, and the extensions have through holes opposite to the first guide grooves 11. The first connecting member is a screw, which passes through the through hole and is threadedly connected to a nut provided in the mounting platform 1, thereby allowing the movable seat 32 to slide on the first guide grooves 11. Through the cooperation of the two first guide grooves 11 and the connecting members, the movable seat 32 can be ensured to move linearly along the first direction X, improving movement accuracy and stability.
[0034] The second coupling component 4 includes a coupling unit 41 and a movable support 42. The movable support 42 is slidably connected to the mounting platform 1. The coupling unit 41 is connected to the movable support 42 and configured to slide along a third direction Z. For example, the mounting platform 1 has a second guide groove 44 extending along a second direction Y. The movable support 42 is slidably connected to the second guide groove 44, allowing it to move along the second direction Y, thereby adjusting the distance between the coupling unit 41 and the positioning seat 2. The movable support 42 has a third guide groove 45 extending along a third direction Z. The coupling unit 41 is slidably disposed in the third guide groove 45, allowing the coupling unit 42 to slide along the third direction Z, expanding spatial freedom, achieving three-dimensional adjustment, and improving testing flexibility.
[0035] The coupling unit 41 includes a second coupling plate 411 and a rotating seat 412. The rotating seat 412 is rotatably connected to the movable bracket 42, and the second coupling plate 411 is disposed on the rotating seat 412. The rotating seat 412 enables the second coupling plate 411 to have an angular rotation function, which can adjust the signal coupling direction and ensure the flexibility and accuracy of the test.
[0036] It should be noted that the first coupling plate 31 and the second coupling plate 411 can use existing coupled antennas, which can test the parameters of the product’s radio frequency consistency, such as transmit power, receive sensitivity and frequency offset, through equivalent coupling.
[0037] In this embodiment, the movable support 42 is provided with a rotation scale 43, which is used to mark the rotation angle of the rotating seat 412. The rotation scale 43 is directly provided on the movable support 42, which makes it convenient for the operator to adjust the angle of the rotating seat 412, improves the intuitiveness of operation, and reduces the difficulty of debugging.
[0038] The mounting platform 1 is equipped with a translation scale 12 near the first coupling component 3 and the second coupling component 4. The translation scale 12 allows the operator to easily and intuitively see the positions of the first coupling component 3 and the second coupling component 4, making it convenient to adjust the distance between them and the positioning seat 2, and reducing the difficulty of debugging.
[0039] The positioning base 2 is provided with a positioning groove 21, the contour of which matches the contour of the product to be tested. The positioning groove 21 can ensure the stability and consistency of the product during the testing process, and ensure the accuracy of the test.
