Description

Technical Field

[0001] This utility model relates to the field of wireless device testing technology, specifically to wireless device testing fixtures and wireless device testing systems. Background Technology

[0002] In the testing process of commonly available wireless devices, the device under test needs to be mounted on a support frame, which is a simple structure that only serves to support the device. This results in low testing efficiency and high workload for wireless devices. Utility Model Content

[0003] The purpose of this invention is to provide a wireless device testing fixture and a wireless device testing system. By improving the structure of the wireless device testing fixture, the fixture can support the wireless device under test at a set height and rotate it at a set angle, which significantly reduces the workload of wireless device testing and improves the efficiency of wireless device testing.

[0004] To achieve the above objectives, this utility model provides a wireless device testing fixture, which includes a lifting part, an adapter part for connecting to a wireless device, and a support part. The support part is rotatable along a horizontal plane. The lifting part is connected between the support part and the adapter part to drive the adapter part to move up and down relative to the support part in the height direction.

[0005] By setting up a lifting part, the adapter can be driven to move up and down along the height direction, thereby supporting and maintaining the wireless test equipment at a set height. By setting up a support part that can rotate along the horizontal plane, the test angle of the wireless test equipment can be adjusted.

[0006] Optionally, the wireless device test fixture also includes several wheels, which are directly or indirectly connected to the bottom of the support. These wheels can switch between an unlocked position and a locked position. In this way, when the wheels are in the locked position, they securely fix the test fixture, preventing movement or shaking during testing. This helps ensure the accuracy and reliability of test results, especially in the testing of wireless devices with high precision requirements. When the wheels are in the unlocked position, the test fixture can be easily moved between different positions without manual handling or the use of other heavy equipment.

[0007] Optionally, the wireless device testing fixture also includes a horizontal turntable, with a support unit located at the top of the turntable and wheels located at the bottom. By setting up the horizontal turntable, the wireless testing equipment can be rotated along the horizontal plane to a set angle.

[0008] Optionally, the wheels are omnidirectional wheels, which are directly mounted on the bottom of the support. The design of the omnidirectional wheels allows the fixture to rotate and move freely within a 360-degree range without prior orientation adjustment, enabling the test fixture to be positioned more accurately on the test point.

[0009] Optionally, the support includes a support body and a plurality of columns extending vertically from the support body, the columns extending beyond the highest point of the support body in the height direction.

[0010] The transition section can contact the top surface of the column.

[0011] Vertically extending columns, through multi-point support (such as a four-column or multi-column structure), distribute the load of the transition section and upper equipment to the supporting body, avoiding local stress concentration and improving the overall structural strength. In addition, the design of the columns extending beyond the highest point of the supporting body ensures that the contact point of the transition section is higher than the surface of the supporting body, enhancing the resistance to lateral forces.

[0012] Optionally, a connecting frame is provided at the top of the lifting unit, the connecting frame is connected to the adapter, and a portion of the adapter protrudes from the connecting frame and can contact the top of the column.

[0013] The support section is partially exposed and directly contacts the top of the main body, forming a "dual-path" load-bearing structure: the load can be transferred to the lifting section through the connecting frame, or directly to the column through the transition section, which significantly improves the overall load-bearing capacity.

[0014] Optionally, the adapter includes a first frame and a second frame stacked vertically and connected in sequence. The first frame is connected to a connecting frame, and the second frame is used to connect to a wireless device. The first and second frames are stacked vertically and connected independently, allowing the two layers of structure to be adjusted according to different needs (such as replacing the first frame with a different specification to adapt to different connecting frames, or replacing the second frame to adapt to different wireless devices), thereby improving the modularity and adaptability of the system.

[0015] Optionally, the lifting unit can be electrically driven or hydraulically driven. Electric drive (such as a servo motor + ball screw) achieves millimeter-level positioning accuracy via an encoder, with a response speed down to milliseconds. Hydraulic drive provides stable thrust through a high-pressure cylinder, enabling high rated loads.

[0016] Optionally, the lifting unit is a scissor lift mechanism. Scissor lift structures have the advantages of large stroke and small size, and their load capacity is strong. The testing fixture has the advantages of miniaturization and a large height adjustment range.

[0017] A wireless device testing system includes a testing platform and wireless device testing fixtures. The testing platform may be a mobile platform or a fixed platform; the mobile platform may include a vehicle.

[0018] Other features and advantages of this specification will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0031] This invention provides a wireless device testing fixture and a wireless device testing system. By improving the structure of the wireless device testing fixture, the fixture can support the wireless device under test at a set height and rotate it at a set angle, which significantly reduces the workload of wireless device testing and improves the efficiency of wireless device testing.

[0032] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0034] Please refer to Figures 1 to 9 , Figure 1 This is a schematic diagram of the structure of the wireless device testing fixture in this embodiment of the utility model, with the lifting part in a lifted state; Figure 2 This is a schematic diagram of the structure of the wireless device testing fixture in this embodiment of the utility model, with the lifting part in the lowered state; Figure 3 yes Figure 1 An explosion diagram; Figure 4 yes Figure 1 A schematic diagram of the lifting section in the middle; Figure 5 yes Figure 1 A schematic diagram of the structure of the adapter in the middle; Figure 6 This is an axonometric view of the wireless device testing fixture located within a movable platform, showing the lifting section in a retracted state; Figure 7 This is an axonometric view of the wireless device testing fixture located within a movable platform, showing the lifting section in a lifted state; Figure 8 This is a side view of the wireless device testing fixture located within a movable platform, showing the lifting section in a retracted state; Figure 9 This is a side view of the wireless device testing fixture located within a movable platform, showing the lifting section in a raised state.

[0035] This utility model provides a testing fixture 10 for a wireless device 7, which is used to support the wireless device 7 during testing. Figures 1-3 As shown, the wireless device 7 test fixture 10 includes a lifting part 1, a connecting part 2 for connecting to the wireless device 7, and a support part 3. The support part 3 supports the lifting part 1 and the connecting part 2. The support part 3 is rotatable along the horizontal plane; the lifting part 1 is connected between the support part 3 and the connecting part 2 to drive the connecting part 2 to move up and down relative to the support part 3 in the height direction.

[0036] By setting the lifting part 1, the adapter part 2 can be driven to move up and down along the height direction, thereby supporting and maintaining the wireless test equipment at a set height. By setting the support part 3 that can rotate along the horizontal plane, the test angle of the wireless test equipment can be adjusted.

[0037] In some embodiments of this application, in order to allow the support 3 to rotate in the horizontal plane, the wireless device 7 test fixture 10 also includes a number of wheels 4, which are directly or indirectly connected to the bottom end of the support 3 and can switch between an unlocked position and a locked position.

[0038] Wheel 4 is a caster wheel, which is directly mounted on the bottom of the support part 3. The design of the caster wheel allows the fixture to rotate and move freely within a 360-degree range without prior orientation adjustment, which allows the test fixture 10 to be positioned more accurately on the test point.

[0039] Specifically, wheel 4 can be a swivel caster with a locking function, equipped with a foot-operated brake or a center locking pin to switch wheel 4 between the locked and unlocked positions. Alternatively, electrically swivel wheel sets, pneumatically locking swivel casters, etc., can also be used. Those skilled in the art can choose according to their needs.

[0040] In this manner, when the wheels 4 are switched to the locked position, they securely hold the test fixture 10 in place, preventing it from moving or shaking during testing. This helps ensure the accuracy and reliability of test results, especially in testing wireless devices 7 with high precision requirements. When the wheels 4 are in the unlocked position, the test fixture 10 can be easily moved between different locations without manual handling or the use of other heavy equipment.

[0041] As an optional example, the wireless device 7 test fixture 10 also includes a horizontal turntable, with a support 3 located at the top of the turntable and wheels 4 located at the bottom. By using the horizontal turntable, the wireless test equipment can be rotated along the horizontal plane to a set angle. The horizontal turntable can be a manual turntable, an electric turntable, or an air-bearing turntable, etc.

[0042] The technical solution of this application will be described below with reference to a specific implementation method.

[0043] Please continue reading Figures 1 to 3 In a specific example, the support part 3 includes a support body, which is a rectangular frame structure extending generally horizontally. Several columns 31b extending vertically from the support body are provided on the support body, with the columns 31b extending beyond the highest point of the support body in the height direction. The connecting part 2 can contact the top surface of the columns 31b.

[0044] In the example shown, the column 31b and the supporting body are an integral structure. The supporting body includes two opposing first beams 31 and two opposing second beams 32. The two first beams 31 are U-shaped square beams, including a first beam 31 segment extending horizontally and a second beam 32 segment extending vertically and perpendicular to the first beam 31 segment. The second beam 32 segment serves as the column 31b. The second beam 32 is connected to the bottom end of the first beam 31 segment.

[0045] Wheels 4 are located at the four corners of the support 3 and are fixedly connected to the first beam 31 and the second beam 32.

[0046] The vertically extending column 31b distributes the load of the transition section 2 and the upper equipment to the supporting body through multi-point support (such as a four-column or multi-column structure), avoiding local stress concentration and improving the overall structural strength. In addition, the design of the column 31b extending beyond the highest point of the supporting body makes the contact point of the transition section 2 higher than the surface of the supporting body, enhancing the resistance to lateral forces.

[0047] In the example shown in the figure, such as Figure 3 and Figure 4 As shown, the lifting unit 1 can be electrically or hydraulically driven. Electric drive (such as a servo motor + ball screw) achieves millimeter-level positioning accuracy via an encoder, with a response speed down to milliseconds. Hydraulic drive provides stable thrust through a high-pressure cylinder, enabling high rated loads.

[0048] Specifically, as shown in the figure, the lifting unit 1 is a scissor lift mechanism. The scissor lift mechanism includes several scissor arm assemblies 11 and an electric drive component 12 or a hydraulic drive component 12. The scissor arm assembly 11 includes several hinged rods forming several parallelogram units. The bottom end of the scissor arm assembly 11 is slidably adapted to the corresponding side of the first beam 31 segment. One end of the drive component 12 is directly or indirectly hinged to the rod, and the other end is hinged to the support unit 3.

[0049] After the drive unit 12 is activated, it can drive the scissor arm assembly 11 to deform under the guidance of the first beam 31 to achieve height adjustment.

[0050] The scissor lift structure has the advantages of large stroke and small size, and its load capacity is strong. The test fixture 10 has the advantages of miniaturization and large height adjustment range.

[0051] like Figure 3 , Figure 4 as well as Figure 5 As shown, the top of the lifting unit 1 is provided with a connecting frame 5, which is hinged to the top of the scissor arm assembly 11 and can be driven by the scissor arm assembly 11 to move up and down along the height direction.

[0052] The connecting bracket 5 is threaded to the adapter 2, or it can be detachably connected to the adapter 2 in other ways. A portion of the adapter 2 is exposed by the connecting bracket 5 and can contact the top of the column 31b.

[0053] In the example shown, the connecting frame 5 is a rectangular structure, and its dimensions are adapted to the scissor arm assembly 11. The adapter 2 presses vertically against the upper surface of the connecting frame 5 and is fixed to the connecting frame 5. The adapter 2 has an approximately rectangular frame structure, with chamfered edges at its four corners to avoid interference with other parts.

[0054] The dimensions of the adapter 2 along both the long and short sides are larger than those of the connecting frame 5, so that the adapter 2 extends beyond the connecting frame 5 on all sides and is opposite to the upper surface of the column 31b located at the bottom.

[0055] The support section 3 is exposed and directly contacts the top of the main body, forming a "dual-path" load-bearing structure: the load can be transferred to the lifting section 1 through the connecting frame 5, or directly to the column 31b through the adapter section 2, which significantly improves the overall load-bearing capacity.

[0056] Please continue reading Figures 3 to 5 The adapter 2 includes a first frame 21 and a second frame 22 that are vertically stacked and connected in sequence. The first frame 21 is connected to the connecting frame 5, and the second frame 22 is used to connect to the wireless device 7. The dimensions of the first connecting frame 5 and the second connecting frame 5 may be the same or different. In the example shown in the figure, the first connecting frame 5 and the second connecting frame 5 have the same structure.

[0057] The first frame 21 and the second frame 22 are stacked vertically and connected independently. The two-layer structure can be adjusted according to different needs (such as replacing the first frame 21 with different specifications to adapt to different connecting frames 5, or replacing the second frame 22 to adapt to different wireless devices 7), thereby improving the modularity and adaptability of the system.

[0058] In another aspect of this application, as Figures 6 to 9 As shown, a wireless device 7 testing system is also provided. The wireless device 7 testing system includes a testing platform and a wireless device 7 testing fixture 10. The testing platform includes a mobile platform 6 or a fixed platform; the mobile platform 6 includes a vehicle. The fixed platform can be set up in a location such as a rooftop, which can be selected by those skilled in the art.

[0059] Figure 6 and Figure 7 The images show the axle-side view of the wireless device 7 test fixture 10 mounted on the vehicle. Figure 8 and Figure 9This is a frontal side view. In this embodiment, during the testing of the wireless device 7, the lifting unit 1 drives the wireless device 7 to a point higher than the highest position of the vehicle, thereby avoiding the influence of the vehicle top on the test results.

[0060] Compared with traditional technical solutions, the advantages of this application are:

[0061] First, this application significantly improves the testing efficiency of wireless device 7, changing the problem of long testing time and low efficiency caused by the need for repeated and multiple test points in the traditional testing process.

[0062] Secondly, the test fixture 10 has a strong structure, which can be adapted to large-size and heavy wireless devices 7. The connection between the test fixture 10 and the test device is completed before the wireless device 7 arrives at the test site, thereby avoiding the problem of repeatedly moving and installing the wireless device 7 in the traditional test process, improving human-machine efficiency and reducing the workload of the test process.

[0063] Third, the test fixture 10 can lift the wireless device 7 to a set height, reducing the impact of surrounding tall objects such as buildings and vehicles on the side view structure of the test device.

[0064] Fourth, operators can control the lifting height of the test equipment remotely, avoiding the need for manual deployment of wireless device 7 in harsh testing environments.

[0065] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
