Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically to a remote control multi-angle signal testing device and system. Background Technology

[0002] In the manufacturing and performance verification process of remote controls, signal reception testing is a crucial step in ensuring product quality and reliability. The core purpose of this test is to verify whether the remote control can stably and accurately receive externally transmitted control signals under different usage conditions. This ensures normal communication between the remote control and the controlled device, preventing user malfunctions and control delays caused by signal reception failures, directly impacting user experience and product market competitiveness.

[0003] Currently, the mainstream solution for remote control signal reception testing in the industry mostly involves fixing the signal receiving board directly above the remote control to create a unidirectional signal transmission and reception test environment. Specifically, this test structure typically includes a test bench, a remote control fixture fixed to the test bench, and a receiving board installed at a specific height directly above the fixture. During testing, a signal of a specific frequency is sent to the remote control, and the receiving board above receives the feedback signal to determine whether the remote control's signal reception performance meets the standards.

[0004] However, with the rapid development of technologies such as smart homes and multi-device interconnection, the actual usage scenarios of remote controls are becoming increasingly complex and diverse. In daily operation, users do not only use the remote control from directly above, but also have multi-angle and multi-directional operation needs. The signal transmission path between the remote control and the controlled device often presents multiple states such as horizontal offset and tilt angle, and the signal reception direction is not limited to a single dimension directly above.

[0005] Existing testing methods that fix the receiver board directly above the remote control have limitations due to their singular reception direction. They can only simulate a very limited number of specific overhead usage scenarios and cannot comprehensively cover multi-angle usage situations in real-world applications. This directly leads to a significant discrepancy between test results and actual performance: on the one hand, some remote controls that pass the overhead test may experience reduced reception sensitivity or signal interruption when operated from multiple angles due to mismatched signal reception angles, failing to meet actual usage needs; on the other hand, this method struggles to accurately detect signal reception defects in non-overhead directions, potentially leading to substandard products entering the market and increasing after-sales costs and brand reputation risks for companies.

[0006] Furthermore, from the perspective of testing efficiency and versatility, existing solutions often require frequent manual adjustments to the position of the receiver board or the angle of the remote control to meet testing needs from different angles. This is not only cumbersome and time-consuming, but also makes it difficult to ensure the consistency and accuracy of test conditions after each adjustment. This seriously affects the efficiency and reliability of remote control signal reception testing and cannot meet the high efficiency and accuracy requirements of large-scale industrial production for testing. Summary of the Invention

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Example 1:

[0024] See Figure 1 and Figure 2 As shown, this embodiment provides a remote control multi-angle signal testing device, which includes: a fixing mechanism 300, the fixing mechanism 300 including a fixing column 320, the fixing column 320 having a receiving groove 321 at its top, the remote control 500 to be tested being inserted into the receiving groove 321; and a testing mechanism 400, the testing mechanism 400 including a connecting frame 420 and multiple signal receiving components 430, the connecting frame 420 being disposed above the fixing mechanism 300, each of the signal receiving components 430 including an adjusting frame 431 and a signal receiving plate 432, the signal receiving plate 432 being connected to the adjusting frame 431 and facing the remote control 500 to be tested, the adjusting frame 431 being detachably connected to the connecting frame 420 to adjust its testing position.

[0025] The remote control multi-angle signal testing device and system described in this utility model fixes the remote control 500 to be tested through a fixing mechanism 300. Then, multiple signal receiving components 430 on the testing mechanism 400 perform multi-angle reception testing on the transmitted signal of the remote control 500, thereby achieving all-round detection of the transmitted signal of the remote control 500. Furthermore, based on the detachable connection structure of the adjustment bracket 431, different test positions can be adjusted according to actual usage needs. Compared with the current fixed test structure, this application has advantages in terms of comprehensive detection, flexibility of use, and scene adaptability. It can overcome the problem of missing weak signal areas such as the sides and rear. At the same time, it can be adapted to test different types of remote controls 500, thus having broad application prospects in this industry.

[0026] In this embodiment, the remote control multi-angle signal testing equipment further includes a platform 100 and a shielding and protection mechanism 200. The shielding and protection mechanism 200 is disposed on the platform 100. The fixing mechanism 300 and the testing mechanism 400 are both disposed inside the shielding and protection mechanism 200. The fixing mechanism 300 includes a mounting plate 310, one side of which is connected to the platform 100, and the other side is connected to the fixing column 320. The testing mechanism 400 includes a connecting plate 410, one end of which is connected to the inner wall of the shielding and protection mechanism 200, and the other end is connected to the connecting frame 420. The platform 100, as the bottom supporting component of the entire testing equipment, has the core function of providing a stable and horizontal mounting reference for the shielding and protection mechanism 200, the fixing mechanism 300, and the testing mechanism 400. The shielding and protection mechanism 200, acting as a signal isolation barrier for the equipment, is mounted on the machine base 100 and completely encloses the fixing mechanism 300 and the testing mechanism 400 within it. Its core function is to isolate electromagnetic signals and noise signals from the external environment from interfering with the testing process, ensuring that the signal receiving component 430 only captures the target signal emitted by the remote controller 500 under test, thus preventing external interference from causing test data distortion. It is typically made of a closed cavity structure using metal shielding material, which can eliminate signal leakage or infiltration caused by gaps, meeting the electromagnetic compatibility (EMC) testing environment requirements.

[0027] Specifically, the shielding and protection mechanism 200 in this embodiment includes a shielding box 210 and a shielding door 220. The shielding door 220 is disposed on one side of the shielding box 210 and can be opened and closed relative to the shielding box 210. Furthermore, the shielding and protection mechanism 200 also includes a locking component 230 and a handle 240. The handle 240 is disposed on the shielding door 220. One side of the shielding door 220 is rotatably connected to the shielding box 210, and the other side is detachably connected to the shielding box 210 through the locking component 230, thereby improving the flexibility of the shielding and protection mechanism 200. This utility model does not impose specific limitations on the specific type and quantity of the handle 240 and the locking component 230.

[0028] Correspondingly, the mounting plate 310 provided in the fixing mechanism 300 in this embodiment serves as a transitional connector between the fixing column 320 and the machine base 100, further optimizing the installation stability and positioning accuracy of the fixing mechanism 300. The mounting plate 310 can increase the contact area between the fixing column 320 and the machine base 100, distributing the weight load of the fixing column 320 and the remote controller 500, and preventing the fixing column 320 from tilting or loosening due to concentrated force after long-term use. At the same time, the mounting plate 310 can be adjusted according to the testing requirements of different models of remote controllers 500 by changing the mounting plate 310 with different hole layouts, thereby improving the adaptability of the fixing mechanism 300 to different testing scenarios. Similarly, the connecting plate 410 provided in the testing mechanism 400 serves as a supporting connector between the connecting frame 420 and the inner wall of the shielding and protection mechanism 200, stably and accurately fixing the connecting frame 420 inside the shielding and protection mechanism 200, ensuring that the installation position of the signal receiving component 430 and the remote controller 500 of the fixing mechanism 300 maintain a preset relative position. The installation height or horizontal position of the connecting plate 410 can be finely adjusted according to the test requirements; the other end is connected to the side of the connecting frame 420 by a buckle or bolt, which can prevent the connecting frame 420 from sagging or shifting due to its own weight or vibration, ensuring that the connecting frame 420 always remains horizontal, thereby ensuring that multiple signal receiving components 430 are distributed at a preset angle, maintaining the integrity and consistency of the detection range, and avoiding the problem that some angle signals cannot be captured due to the offset of the connecting frame 420.

[0029] See Figure 3 and Figure 4As shown, the fixing mechanism 300 in this embodiment serves as the reference positioning component of the device. Its core function is to ensure that the remote control 500 under test remains in a fixed position throughout the signal testing process, avoiding deviations in test data due to displacement. The fixing column 320 provides rigid support for the overall structure, ensuring it remains stable during testing. The receiving slot 321 at the top of the fixing column 320 is precisely fitted to the outline of the remote control 500 under test. Furthermore, the depth design of the receiving slot 321 in this embodiment ensures that after the remote control 500 is inserted, its signal transmission window maintains a preset distance of 10-50cm from the signal receiving component 430 of the testing mechanism 400 above, providing a unified reference position for subsequent multi-angle signal reception and solving the problems of easy displacement and poor positioning consistency of the remote control 500 in current fixing structures.

[0030] Specifically, the fixing column 320 includes a body 322, an abutment block 323, and a support block 324. The support block 324 is connected to the middle of the body 322 in the height direction. The abutment block 323 is supported on the support block 324 and is detachably connected to the body 322. The body 322, the abutment block 323, and the support block 324 together form the receiving groove 321. Specifically, the body 322 has an overall vertical column structure, and its bottom is rigidly connected to the mounting plate 310 of the fixing mechanism 300, providing a stable mounting base for the abutment block 323 and the support block 324. At the same time, it bears the weight load of the entire fixing column 320 and the remote controller 500 under test, ensuring that the fixing column 320 does not shake or deform during the test. In addition, the middle part of the height direction of the main body 322 is reserved with an installation position that is compatible with the support block 324, so as to realize the precise positioning and fixation of the support block 324. The surface of the main body 322 facing the receiving groove 321 is kept flat and smooth, which can cooperate with the abutment block 323 and the support block 324 to form a side wall of the receiving groove 321, providing stable lateral support for the remote control 500 and preventing the remote control 500 from shifting laterally after being plugged in.

[0031] The support block 324 is connected to the middle of the body 322 in the height direction and has a horizontal block structure. Its main function is to provide a bottom support surface for the receiving slot 321. The support block 324 can make the bottom of the remote control 500 under test stable, and avoid the remote control 500 tilting due to uneven support surface, which would affect the relative position of the signal transmission window and the test mechanism 400.

[0032] The abutment block 323 is supported on the support block 324 and is detachably connected to the body 322 by bolts. Its core function is to cooperate with the body 322 and the support block 324 to form a receiving groove 321 that fits the shape of the remote control 500, and to achieve flexible adaptation to remote controls 500 of different widths. The side of the abutment block 323 facing the receiving groove 321 can be designed as a flat or curved shape according to the side profile of the remote control 500, forming the two side walls of the receiving groove 321 together with the body 322. The width of the receiving groove 321 is limited by the distance between the two, forming a lateral clamping limit for the remote control 500, preventing the remote control 500 from lateral displacement due to vibration during testing. The detachable connection design gives the receiving groove 321 the characteristic of adjustable width. When testing remote controls 500 of different widths, simply remove the current abutment block 323 and replace it with an abutment block 323 of the corresponding width to change the width of the receiving groove 321 without replacing the entire fixing post 320. This greatly improves the compatibility of the fixing mechanism 300 with different models of remote controls 500 and solves the problem that the current fixed receiving groove 321 cannot be compatible with multiple specifications of products.

[0033] Specifically, in this embodiment, a disassembly groove 325 is provided on the side wall of the main body 322 and / or the side wall of the abutment block 323. The disassembly groove 325 is located at the contact point between the main body 322 and the abutment block 323, so that the operator can apply force to the abutment block 323 and facilitate the disassembly and assembly of the abutment block 323.

[0034] See Figure 5 As shown, the testing mechanism 400 in this embodiment is used to complete signal reception and test position adjustment. It is composed of a connecting frame 420 and multiple signal receiving components 430. The connecting frame 420 provides a unified mounting carrier and spatial reference for the multiple signal receiving components 430. The connecting frame 420 is provided with multiple adjustment holes 421. The multiple adjustment frames 431 are detachably connected to the adjustment holes 421 by connecting pins. The hole spacing of the adjustment holes 421 is adapted to the adjustment frames 431 of the signal receiving components 430 to ensure that each signal receiving component 430 can be installed at a preset angle. At the same time, the rigid structure of the frame itself can avoid positional displacement caused by vibration, providing a stable mounting foundation for the signal receiving components 430.

[0035] Furthermore, in this embodiment, the signal receiving board 432 serves as the core detection element. On the side facing the remote controller 500 under test, it integrates a signal sensing chip and a data transmission interface. It can capture infrared signals, radio frequency signals, etc. emitted by the remote controller 500 in real time, and convert data such as signal strength and transmission delay into electrical signals, which are then transmitted to an external analysis system via a data cable. The size and sensing sensitivity of the receiving board are matched to ensure that the transmitted signals of remote controllers 500 with different power levels can be accurately received within a preset test distance, avoiding detection blind spots caused by insufficient sensitivity.

[0036] The adjustment bracket 431 serves as an intermediate connector between the connecting frame 420 and the signal receiving board 432. Its core function is to enable flexible adjustment and stable fixation of the test position. The adjustment bracket 431 adopts a detachable connection structure. When it is necessary to adjust the test position, simply remove the adjustment bracket 431 from the connecting frame 420 and reinstall it into the adjustment hole 421 at the target position to complete the angle or distance adjustment of the signal receiving board 432.

[0037] Furthermore, the adjustment frame 431 is provided with a clearance hole 4311. The edge of the signal receiving board 432 is supported and connected to the adjustment frame 431, and the receiving end of the signal receiving board 432 is positioned facing the remote control 500 to be tested through the clearance hole 4311. The size of the clearance hole 4311 matches the size of the receiving end of the signal receiving board 432, and the center of the hole is precisely aligned with the center of the receiving end of the signal receiving board 432. Its main function is to provide an unobstructed signal path for the receiving end of the signal receiving board 432, preventing the panel of the adjustment frame 431 from blocking the signal emitted by the remote control 500, ensuring that the signal can be directly transmitted to the receiving end, and solving the problems of signal attenuation and decreased receiving sensitivity that may occur if the panel of the adjustment frame 431 directly covers the receiving end.

[0038] The remote control multi-angle signal testing device in this embodiment also includes a control mechanism, which includes a signal transmitting module and a signal receiving module. The remote control 500 to be tested is connected to the signal transmitting module, and multiple signal receiving boards 432 are respectively connected to the signal receiving module. As the core of signal interaction and test control, the control mechanism of this remote control multi-angle signal testing device establishes a signal transmission and data acquisition link between the remote control 500 to be tested and multiple signal receiving boards 432 through the coordinated operation of the signal transmitting module and the signal receiving module. The signal transmitting module, connected to the remote control 500 to be tested, primarily sends preset control commands to the remote control 500 to drive it to stably transmit signals according to test requirements. The multiple signal receiving boards 432 are respectively connected to the signal receiving module, which is responsible for receiving the signals transmitted by the remote control 500 collected by each signal receiving board 432 and transmitting signals from different angles. The signal receiving board 432 summarizes data such as signal strength, transmission delay, and signal integrity. On the other hand, it can perform preliminary processing on the summarized data and then transmit the processed test data to an external analysis system or display terminal for operators to view the test results and determine whether the signal transmission performance of the remote control 500 meets the standards. At the same time, the signal receiving module can also work in conjunction with the signal transmitting module to adjust the command parameters of the signal transmitting module in real time according to the received signal data, ensuring dynamic optimization of the testing process. Ultimately, it realizes automated and accurate testing of the signal transmission performance of the remote control 500 at multiple angles, solving the problems of scattered data acquisition, low testing efficiency, and large result errors in traditional testing.

[0039] Example 2:

[0040] This embodiment provides a remote control multi-angle signal testing system, which includes the aforementioned remote control multi-angle signal testing equipment.

[0041] In summary, the remote control multi-angle signal testing device and system described in this utility model fixes the remote control 500 to be tested through the fixing mechanism 300, and then performs multi-angle reception testing on the transmitted signal of the remote control 500 through multiple signal receiving components 430 on the testing mechanism 400. This achieves all-round detection of the transmitted signal of the remote control 500. Furthermore, based on the detachable connection structure of the adjustment bracket 431, different test positions can be adjusted according to actual usage needs. Compared with the current fixed test structure, this application has advantages in terms of comprehensive detection, flexibility of use, and scene adaptability. It can overcome the problem of missing weak signal areas such as the sides and rear, and can be adapted to test different types of remote controls 500. Therefore, it has broad application prospects in this industry.
