Description

Technical Field

[0001] This disclosure relates to the field of temperature testing technology for wallpaper-type audio-visual products, and more particularly to testing devices. Background Technology

[0002] As the color TV industry enters the wallpaper era, screen technology has undergone fundamental innovation. Users' usage environments and modes for audio-visual products (such as wallpaper TVs) are becoming increasingly diverse. This places higher demands on the temperature testing at the product setup front end. Temperature indicators need to be controlled by accurately simulating the actual usage environment to avoid frequent reports of overheating issues from sales and users.

[0003] Currently, temperature testing of audio-visual products largely relies on traditional wooden enclosure fixtures. However, these existing fixtures have many shortcomings and cannot meet testing requirements. Specific problems are as follows: Firstly, the existing wooden cabinet fixtures have fixed and non-adjustable dimensions, and their sides and tops lack flexible opening and closing structures. This makes it difficult to smoothly place large-sized products under test inside the fixtures. Furthermore, separate test cabinets are required for audio and video products of different sizes, ranging from 32 inches to 100 inches. This results in a large demand for test fixtures, a large space occupation, and high costs, making it unsuitable for the centralized testing needs of products of multiple sizes.

[0004] Secondly, the existing wooden box-type tooling lacks a controllable enclosed space structure, making it impossible to adjust the internal sealing state of the tooling according to testing needs. This makes it difficult to reproduce the actual spatial environment when the product is displayed at the sales end or used at home by users. As a result, the testing environment deviates significantly from the actual usage scenario of the product, and the test data cannot accurately reflect the actual temperature performance of the product. Consequently, it cannot provide an effective basis for adjusting the settings, and there is still a risk that the sales end and users will report that the temperature is too high.

[0005] Therefore, the aforementioned technical deficiencies directly affect the convenience, accuracy, and cost control of temperature testing for audio-visual products, and there is an urgent need for a testing device that can be adapted to products of multiple sizes and can simulate actual usage spaces. Utility Model Content

[0006] This disclosure provides a testing device to solve the technical problems of existing temperature testing devices for audio and video products, which lack convenience, accuracy, and cost control.

[0007] The testing device provided by this utility model is used for temperature testing of audio-visual products. It includes a front panel, a top cover, side baffles, and a bottom support plate. The top cover is rotatably connected to the top of the front panel. The side baffles are arranged in pairs on both sides of the front panel, and each side baffle is rotatably connected to both sides of the front panel. The bottom support plate is connected to the bottom of the front panel. When the testing device is in a first state, the top cover and both side baffles are closed, so that the top cover, both side baffles, and the bottom support plate together surround the same side of the front panel and form a large accommodating space. When the testing device is in a second state, the top cover and both side baffles are in an open state after being flipped over, so that a large-sized product to be tested can be placed in the large accommodating space.

[0008] The testing device further includes a first rotating connector and a second rotating connector. The top cover plate is rotatably connected to the front side plate through the first rotating connector, and the two side baffles are rotatably connected to the two sides of the front side plate through a second rotating connector.

[0009] When the top cover is in the flipped-open state, the top cover is configured to be positioned at a first preset position following the rotation of the first rotating connector.

[0010] When both side panels are in the flipped-open state, one of the front side panels is configured to be positioned in a second preset position following the rotation of one of the second rotating connectors, and the other front side panel is configured to be positioned in a third preset position following the rotation of the other second rotating connector. The first preset position, the second preset position, and the third preset position are all located away from the side of the front panel that has the large accommodating space.

[0011] The testing device further includes an adjustment component installed in the large accommodating space. The adjustment component includes a first upright plate and a second upright plate arranged opposite to each other. The first upright plate is configured to slide in cooperation with the bottom support plate, and the second upright plate is configured to slide in cooperation with the bottom support plate, so that the first upright plate and the second upright plate can move relatively away from each other or relatively close to each other within the large accommodating space.

[0012] The first and second upright plates are provided with multiple transverse mounting positions distributed longitudinally. The adjustment assembly also includes a transverse partition, which is configured to be selectively inserted between two transverse mounting positions at the same horizontal height, so that a small accommodating space for accommodating small-sized products under test is formed between the transverse partition, the first upright plate and the second upright plate.

[0013] The adjustment assembly further includes a sliding component, which includes a slide rail component mounted on the bottom support plate, a first slider component mounted on the bottom of the first upright plate, and a second slider component mounted on the bottom of the second upright plate. The slide rail component includes a first slide rail and a second slide rail, which are spaced apart and parallel to each other. The first slider component is configured to slide with the first slide rail and the second slide rail respectively, and the second slider component is configured to slide with the first slide rail and the second slide rail respectively.

[0014] The first slider component includes a first connecting block, a first sliding sub-block, a second sliding sub-block, and a first corner connector. The first sliding sub-block and the second sliding sub-block are respectively installed on both sides of the first connecting block. The first sliding sub-block is slidably assembled with the first slide rail, and the second sliding sub-block is slidably assembled with the second slide rail. The two sides of the first upright plate are respectively connected to the top surface of the first connecting block through a first corner connector. The first slider component further includes a first limiting screw. After the first sliding sub-block slides into place, the first limiting screw is used to thread a connection with one side of the first sliding sub-block. The bottom surface of the stud of the first limiting screw is configured to abut against the side of the first slide rail.

[0015] The second slider component includes a second connecting block, a third sliding sub-block, a fourth sliding sub-block, and a second corner connector. The third sliding sub-block and the fourth sliding sub-block are respectively installed on both sides of the second connecting block. The third sliding sub-block is slidably assembled with the first slide rail, and the fourth sliding sub-block is slidably assembled with the second slide rail. The two sides of the second vertical plate are respectively connected to the top surface of the second connecting block through a second corner connector. The second slider component also includes a second limiting screw. After the third sliding sub-block slides into place, the second limiting screw is used to thread a connection with one side of the third sliding sub-block. The bottom surface of the stud of the second limiting screw is configured to abut against the side of the first slide rail.

[0016] A wall-mounting component is provided on the side of the front panel facing away from the wall, and the wall-mounting component is located within the accommodating space.

[0017] Compared with the prior art, the technical solutions provided in this disclosure have the following advantages: The testing device provided in this disclosure, through the rotatable connection of the top cover, side baffles, and front panel, and its dual-state setting—closing to form a large accommodating space and opening to facilitate the placement of large-sized products—precisely solves the core defects of existing wooden testing fixtures. Specifically, by rotatably opening the top cover and two side baffles in the second state, spatial obstacles to product placement are completely eliminated. Whether it is a small 32-inch product or a large 100-inch wallpaper TV, it can be easily placed on the basic support structure formed by the bottom support plate and the front panel. At the same time, there is no need to customize fixtures for different sizes; one device can adapt to the testing needs of audio-visual products of all sizes, significantly reducing the number of fixtures and lowering space occupation and testing costs. Meanwhile, by closing the top cover and two side baffles in the first state, together with the front panel and bottom support plate, a closed large accommodating space is formed. This space can accurately reproduce the product's surrounding environment when displayed at the sales end or used at home (such as wall adhesion, space airtightness, etc.), making the temperature testing process completely match the actual use scenario of the product, and the test data is more valuable.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0025] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0026] refer to Figure 1 and Figure 2 The testing device provided in this embodiment is used for temperature testing of audio-visual products. It includes a front panel, a top cover, side baffles, and a bottom support plate. The top cover is rotatably connected to the top of the front panel. The side baffles are arranged in pairs on both sides of the front panel, and each side baffle is rotatably connected to both sides of the front panel. The bottom support plate is connected to the bottom of the front panel. When the testing device is in a first state, the top cover and both side baffles are closed, so that the top cover, both side baffles, and the bottom support plate together surround the same side of the front panel and form a large accommodating space. When the testing device is in a second state, the top cover and both side baffles are in an open state after being flipped over, so that a large-sized product to be tested can be placed in the large accommodating space.

[0027] For example, the rotatable connection between the top cover and the front panel can refer to the top cover being connected to the top of the front panel via a hinge, etc.

[0028] For example, the side panel is also connected to the two sides of the front panel via a similar connector. The connector allows the cover or panel to rotate flexibly around the connecting shaft. It should be noted that the rotation angle range simultaneously meets the requirements of fully opening and fully closing.

[0029] For example, after rotation, the cover or side plate can be fixed in the target state by means of a snap-fit ​​or positioning pin, such as being fixed at the same horizontal position as the front side plate after opening, or being fixed at a position perpendicular to the front side plate after opening, and being able to fit tightly with the front side plate or bottom support plate after closing.

[0030] It should be noted that by rotating and opening the top cover and side panels, the space obstruction on the top and sides of the fixture can be completely eliminated, providing an unobstructed insertion channel for large-sized products, such as a 100-inch wallpaper TV; when closed, it can form a closed space to meet the needs of simulating the actual use environment.

[0031] For example, the large capacity space refers to the five-sided enclosed space formed by the front side plate (as the back support surface), the top cover plate (as the top closed surface), the two side plates (the two side closed surfaces), and the bottom support plate (the bottom bearing surface) when the test device is in the first state, that is, when the top cover plate and the side baffles are closed. The space size is set based on the maximum adaptation requirements of audio and video products, while also being compatible with the test scenarios of small-sized products.

[0032] For example, the current maximum dimensions of a 100-inch wallpaper TV are approximately 220cm long, 10cm wide, and 125cm high. Considering the space required for thermocouple mounting and heat dissipation during testing, the final enclosed space can cover an area of ​​240cm long, 30cm wide, and 140cm high. This allows for the accommodation of a 100-inch product with sufficient space for testing operations. Additionally, adjustable partitions can be added later, such as internal movable partitions, to accommodate smaller 32-inch products. For example, a 32-inch product is approximately 75cm long and 45cm high. The space can be divided into smaller, more suitable areas using partitions to prevent distortion of the testing environment due to excessive space.

[0033] For example, the bottom support plate is a horizontally positioned rigid board, made of the same material as the front panel, such as 4cm thick solid wood, ensuring load-bearing strength. For example, one end of the bottom support plate is vertically fixed to the bottom end of the front panel. This connection can be achieved through bolt fastening or mortise and tenon joints to ensure structural stability, forming an L-shaped basic frame. The front panel serves as the back support surface of the product, simulating the back support of a user's home wall or a sales display shelf. The bottom support plate serves as the bottom load-bearing surface of the product, simulating the load-bearing function of a desktop or TV cabinet. Thus, the bottom support plate and the front panel together constitute the product's double-fixed structure. This solves the potential problem of unstable placement of existing fixture products, enabling it to support the weight of products of different sizes and adapt to different placement methods, such as base placement or wall mounting, providing a stable testing benchmark for temperature testing. For example, a 100-inch wallpaper TV weighs approximately 30kg, and the 4cm thick solid wood board and vertical fixing structure can meet the load-bearing requirements.

[0034] For example, when testing a stand-mounted audio-visual product, such as a regular desktop TV, the product stand is placed directly on the base support plate, and the front panel can be fitted to the back of the product to simulate a wall-mounted scenario. Anti-slip pads can be added to the surface of the base support plate to prevent the product from sliding. At the same time, stabilizing structural components, such as horizontal reinforcing beams or anti-slip pads, are also provided under the base support plate to prevent the device from shaking during the test and affecting the accuracy of the data.

[0035] When testing a wall-mounted wallpaper TV, a fixing clip that matches the TV wall mount can be pre-installed on the front panel surface. The TV can then be fixed to the front panel using the wall mount to simulate a wall-mounted scenario in a user's home. At this time, the bottom support plate can serve as an auxiliary support to prevent the TV from falling during installation, or it can be used to place equipment such as thermocouple testers during testing, thus balancing safety and practicality.

[0036] The testing device provided in this disclosure, through the rotatable connection of the top cover, side baffles, and front panel, and its dual-state setting—closing to form a large accommodating space and opening to facilitate the placement of large-sized products—precisely solves the core defects of existing wooden testing fixtures. Specifically, by rotatably opening the top cover and two side baffles in the second state, spatial obstacles to product placement are completely eliminated. Whether it is a small 32-inch product or a large 100-inch wallpaper TV, it can be easily placed on the basic support structure formed by the bottom support plate and the front panel. At the same time, there is no need to customize fixtures for different sizes; one device can adapt to the testing needs of audio-visual products of all sizes, significantly reducing the number of fixtures and lowering space occupation and testing costs. Meanwhile, by closing the top cover and two side baffles in the first state, together with the front panel and bottom support plate, a closed large accommodating space is formed. This space can accurately reproduce the product's surrounding environment when displayed at the sales end or used at home (such as wall adhesion, space airtightness, etc.), making the temperature testing process completely match the actual use scenario of the product, and the test data is more valuable.

[0037] It should be noted that in the second state, the top cover is opened (rotated upwards to be horizontal or vertical, and the side panels are rotated outwards to be parallel or vertical), and the 65-inch TV is fixed to the front panel using the wall mount. Thermocouples are then attached to key heat-generating areas such as the TV back panel and frame. Switching back to the first state, the top cover and side panels are closed. In this state, the enclosed large space simulates the sealed environment formed by the TV being wall-mounted, the wall, and surrounding furniture. For example, the distance between the TV and the left-side wardrobe is 10cm, and the distance between the TV and the top wall cabinet is 15cm, consistent with the actual home layout. After starting the test, the measured temperature data can accurately reflect the actual heat generation during user use.

[0038] Considering the rotation scheme of the top cover plate and the two side baffles, the testing device provided in this embodiment further includes a first rotating connector and a second rotating connector. The top cover plate is rotatably connected to the front side plate through the first rotating connector, and the two side baffles are rotatably connected to the two sides of the front side plate through one of the second rotating connectors.

[0039] In this way, the first and second rotating connectors, as force transmission components, can adapt their structural parameters according to the different weights and stress characteristics of the top cover and side baffles. For example, since the top cover needs to cover the top of the device, it usually uses a plate of the same thickness as the front side plate, making it heavier. The first rotating connector can be a heavy-duty hinge with damping. The side baffle is relatively lighter, so the second rotating connector can be a lightweight positioning hinge. This ensures that the cover or baffle moves smoothly around the connecting shaft during rotation, without offset, jamming, or shaking. For instance, when the top cover rotates upward to a horizontal open state via the first rotating connector, the damping structure can prevent the cover from falling rapidly due to its own weight and impacting the test personnel or product. When the side baffle rotates outward to a vertical open state via the second rotating connector, the positioning buckle on the hinge can fix the baffle in this position, preventing the baffle from closing due to accidental contact during the test. This ensures the safety of the operating space when placing large-sized products and avoids interference with the testing process caused by loose rotating components.

[0040] It should be noted that the rotation requirements of the top cover and side baffles are fundamentally different. The top cover frequently switches between a vertically closed state, used to bear the pressure of the upper space, and a horizontally open state without load, placing higher demands on the load-bearing capacity and fatigue strength of the connectors. The side baffles, on the other hand, need to switch between a vertically closed state, sealing the side space, and an outwardly open state, bearing their own weight. This solution uses a categorized approach to the connectors, allowing the first rotating connector to focus on load-bearing and damping, and the second rotating connector to focus on positioning and flexibility. This avoids the problems caused by using generic connectors, such as deformation of the top cover connector due to insufficient load-bearing capacity or sealing failure of the side baffle connector due to inaccurate positioning.

[0041] For example, both the first and second rotating connectors adopt standardized detachable structures, such as being fixed to the front side plate, cover plate, or baffle by bolts. When a connector wears out, such as when the hinge shaft rusts and causes rotational jamming, or when a connector is damaged, it is not necessary to disassemble and replace the entire structure such as the top cover plate or side baffle. Only the corresponding connector needs to be disassembled and replaced, which reduces the complexity of maintenance operations and the cost of component replacement. For example, if the second rotating connector of the side baffle fails to position due to long-term use, the tester can directly unscrew the connector fixing bolts and replace it with a new lightweight positioning hinge. The entire maintenance process can be completed in a short time, avoiding long-term interruptions to testing work due to overall structural repairs.

[0042] Considering the flip-open state scheme of the top cover and side baffles, in the testing device provided in this embodiment, when the top cover is in the flipped-open state, the top cover is configured to be positioned at a first preset position following the rotation of the first rotating connector; when both side baffles are in the flipped-open state, one of the front side panels is configured to be positioned at a second preset position following the rotation of one of the second rotating connectors, and the other front side panel is configured to be positioned at a third preset position following the rotation of the other second rotating connector; the first preset position, the second preset position, and the third preset position are all opposite to the side of the front side panel having the large accommodating space.

[0043] In this way, the top cover is positioned at the first preset position away from the receiving space after opening, and the side panels are positioned at the second and third preset positions respectively, maximizing the operating space for the placement and testing preparation of large-size audio-visual products. Considering the handling and testing needs of audio-visual products, especially large-size wallpaper TVs such as 100 inches, this preset positioning setting prevents the top cover and side panels from tilting or obstructing the receiving space after opening. Test personnel can smoothly move large-size products onto the load-bearing structure formed by the bottom support plate and the front side plate without additional support. Simultaneously, thermocouple sensors can be flexibly attached to the product surface, completely solving the problem of panel wobbling hindering operation after opening traditional fixtures.

[0044] This preset positioning scheme also ensures rapid switching between open and closed states of the testing device and efficient space utilization. Since the first, second, and third preset positions are all away from the accommodating space, the top cover and side baffles, when opened, will not occupy the testing operation area around the accommodating space, nor will they collide with surrounding equipment when the device moves. At the same time, the fixed preset positions eliminate the need for repeated adjustments and alignment when the panels are closed. They can be quickly repositioned along the rotating connector to form a large, sealed accommodating space with the front side panel and bottom support plate, ensuring that subsequent temperature tests can quickly enter a stable environmental state.

[0045] Considering the possibility of distinguishing smaller accommodating spaces within a large accommodating space, the testing device provided in this embodiment further includes an adjustment component. The adjustment component is installed in the large accommodating space and includes a first upright plate and a second upright plate arranged opposite to each other. The first upright plate is configured to slide in cooperation with the bottom support plate, and the second upright plate is configured to slide in cooperation with the bottom support plate, so that the first upright plate and the second upright plate can move relatively away from each other or relatively close to each other within the large accommodating space.

[0046] In this way, by setting up an adjustment component with sliding first and second uprights within a large storage space, the distance between the uprights and the bottom support plate can be adjusted according to the actual shape and usage scenario requirements of different small-sized products from 32 inches to 100 inches. This allows for flexible division of the large storage space into smaller storage areas suitable for smaller products. This avoids the deviation between the testing environment (such as airflow and temperature field) and the actual usage scenario (such as a small TV embedded in a small cabinet or placed in a narrow TV cabinet) caused by placing small-sized products directly in a large storage space, ensuring the accuracy of temperature test data for small-sized products. It also eliminates the need for additional custom-made testing fixtures for different small-sized products, further enhancing the adaptability of a single device to full-size audio-visual products. At the same time, the sliding mechanism makes the distance adjustment operation convenient and allows for quick switching to different testing states for different small-sized products, improving testing efficiency.

[0047] Considering the scheme of further dividing the small accommodating space between the two upright plates, in the testing device provided in the embodiments of this disclosure, the first upright plate and the second upright plate are provided with a plurality of longitudinally distributed transverse mounting positions. The adjustment component also includes a transverse partition, which is configured to be selectively inserted between two of the transverse mounting positions at the same horizontal height, so that a small accommodating space for accommodating a small-sized product under test is formed between the transverse partition, the first upright plate and the second upright plate.

[0048] For example, the lateral mounting position can be a mounting hole or mounting groove formed on the first or second vertical plate, depending on the required accommodating space size.

[0049] In this way, by setting multiple horizontal mounting positions vertically distributed on the first and second uprights, and combining them with horizontal partitions that can be selectively inserted into the same horizontal mounting position, the installation position of the horizontal partitions can be flexibly adjusted according to the different small-sized products under test, such as 24-inch and 32-inch audio-visual equipment of different heights, and the actual usage scenarios, such as small-sized TVs embedded in layered cabinets or placed on display racks of different heights. This allows the small enclosure space enclosed by the horizontal partitions and uprights to accurately adapt to the product size in the height dimension. This avoids the deviation of the test environment, such as vertical airflow and temperature field distribution, from the actual usage scenario caused by the excessive height of the enclosure space for small-sized products, ensuring that the temperature test data is more in line with the actual usage situation. Furthermore, it eliminates the need to set up additional dedicated partition structures for small-sized products of different heights. The test space specifications can be quickly switched simply by selecting different horizontal mounting positions. This is convenient to operate and further reduces tooling adjustment costs, enhancing the device's ability to accurately adapt to multiple sizes of small-sized audio-visual products.

[0050] Considering the specific scheme of the sliding assembly of the first upright plate relative to the bottom support plate, in the test device provided in the embodiments of this disclosure, the adjustment component further includes a sliding member. The sliding member includes a slide rail member installed on the bottom support plate, a first slider member installed on the bottom of the first upright plate, and a second slider member installed on the bottom of the second upright plate. The slide rail member includes a first slide rail and a second slide rail. The first slide rail and the second slide rail are spaced apart and arranged parallel to each other. The first slider member is configured to slide and assemble with the first slide rail and the second slide rail respectively. The second slider member is configured to slide and assemble with the first slide rail and the second slide rail respectively.

[0051] In this way, by setting the first and second slide rails parallel to each other and assembling the first and second sliders to correspond to the first and second upright plates respectively, bidirectional limiting guidance can be provided for the sliding of the first and second upright plates. This prevents the upright plates from shifting or tilting during the adjustment of the spacing, ensuring that the upright plates always remain vertical. This, in turn, guarantees the levelness and regularity of the small accommodating space during the subsequent installation of the transverse partition, preventing distortion of the test environment due to the tilting of the upright plates. At the same time, the sliding assembly structure of the slider and the double slide rails makes the sliding process of the upright plates smoother and more stable, without the need for additional force to correct the position. Even if frequent adjustments are made to adapt to small-sized products of different widths, such as the width difference between 32-inch and 55-inch products, the positioning can be quickly and accurately achieved, reducing adjustment time. In addition, the support structure of the double slide rails can also improve the stability of the upright plates in supporting the transverse partitions and products, preventing the sliding parts from loosening after long-term use, further ensuring the structural reliability of the testing device and the accuracy of test data during long-term use.

[0052] Considering the specific composition of the first slider component in the aforementioned scheme, in the test device provided by this disclosure embodiment, the first slider component includes a first connecting block, a first sliding sub-block, a second sliding sub-block, and a first corner connector. The first sliding sub-block and the second sliding sub-block are respectively installed on both sides of the first connecting block. The first sliding sub-block is slidably assembled with the first slide rail, and the second sliding sub-block is slidably assembled with the second slide rail. The two sides of the first upright plate are respectively connected to the top surface of the first connecting block through a first corner connector. The first slider component further includes a first limiting screw. After the first sliding sub-block slides into place, the first limiting screw is used to thread a connection with one side of the first sliding sub-block. The bottom surface of the stud of the first limiting screw is configured to abut against the side of the first slide rail.

[0053] In this way, the first slider component is equipped with a first sliding sub-block and a second sliding sub-block on both sides of the first connecting block to adapt to the double slide rails. With the first corner connector, the first upright plate is vertically and stably connected to the top surface of the connecting block. This not only ensures that the force is evenly distributed when the upright plate slides through the sliding sub-blocks on both sides, avoiding sliding jamming or tilting of the upright plate caused by force on one side, but also strengthens the connection strength between the upright plate and the sliding component with the corner connector, preventing structural loosening when the upright plate bears the cross partition and small-sized products. At the same time, the first limiting screw abuts against the side of the slide rail through the threaded connection after the sliding sub-block is in place, which can accurately lock the position of the upright plate and prevent the upright plate from shifting due to device vibration or airflow disturbance during the test. This ensures that the size of the small accommodating space remains stable and does not need to be repeatedly adjusted to calibrate the space specifications. This not only improves the consistency of the testing environment for small-sized products, but also further simplifies the fixing operation after the upright plate spacing is adjusted, ensuring the efficiency and data accuracy of testing multiple batches of small-sized products.

[0054] Considering the specific composition scheme of the second slider component, in the test device provided in this embodiment, the second slider component includes a second connecting block, a third sliding sub-block, a fourth sliding sub-block, and a second corner connector. The third sliding sub-block and the fourth sliding sub-block are respectively installed on both sides of the second connecting block. The third sliding sub-block is slidably assembled with the first slide rail, and the fourth sliding sub-block is slidably assembled with the second slide rail. The two sides of the second vertical plate are respectively connected to the top surface of the second connecting block through a second corner connector. The second slider component also includes a second limiting screw. After the third sliding sub-block slides into place, the second limiting screw is used to thread a connection with one side of the third sliding sub-block. The bottom surface of the stud of the second limiting screw is configured to abut against the side of the first slide rail.

[0055] In this way, the second slider component is equipped with a third sliding sub-block and a fourth sliding sub-block on both sides of the second connecting block to adapt to the double slide rail. With the second corner connector, the second upright plate is vertically and stably connected to the top surface of the connecting block. This not only ensures that the second upright plate slides smoothly due to the balanced force on both sides, preventing jamming or tilting, but also strengthens the structural stability of the second upright plate in supporting the crossbeam and small-sized products through the corner connector, preventing loosening of the connection during long-term use. At the same time, after the third sliding sub-block is in place, the second limiting screw abuts against the side of the first slide rail to lock, which can form a double-sided locking effect with the limiting structure of the first slider component. This ensures that the distance between the first and second upright plates remains stable and does not deviate from the size of the small accommodating space due to the displacement of the upright plates during the test. This further ensures the consistency of the test environment for small-sized audio and video products. Moreover, the locking operation is simple and can be completed without complicated tools, effectively improving the fixing efficiency and test reliability after the upright plate distance is adjusted.

[0056] Considering the wall-mounted installation scenario of the testing device, in the testing device provided in this embodiment, a wall-mounting component is provided on the side of the front panel facing away from the wall, and the wall-mounting component is located within the accommodating space.

[0057] For example, the wall mount can be configured according to the actual wall material and installation requirements to ensure that the testing device of this embodiment can be stably used for temperature testing of audio and video products.

[0058] By placing the wall-mounting component on the side of the front panel away from the wall, i.e., within a large storage space, the testing requirements for wall-mounted audio-visual products can be precisely met, especially the temperature testing requirements for wallpaper TVs. This simulates the contact state and stress environment between the product and the wall when the product is wall-mounted, solving the problem of discrepancies between test data and actual usage caused by the inability of existing testing fixtures to reproduce wall-mounted scenarios. At the same time, the placement of the wall-mounting component within the storage space does not interfere with the adjustment components' division of the small storage space or the assembly and adjustment of the vertical and horizontal partitions. This allows for the testing of both wall-mounted and base-mounted audio-visual products on the same device, eliminating the need for additional wall-mounted test brackets. This further simplifies the testing process, enhances the device's adaptability to products in different installation scenarios, and ensures the authenticity and reference value of temperature test data for wall-mounted products.

[0059] Considering the movement scheme of the test device 1, the test device 1 of this embodiment is also provided with rollers 3. The rollers 3 are installed below the bottom support plate 14. There can be n rollers 3, where n is a number greater than 4. At least one roller 3 is provided at each of the four corners of the bottom support plate 14.

[0060] Considering the stable connection scheme between the front side plate 11 and the bottom support plate 14 in the test device 1, the test device 1 of this embodiment is further provided with a reinforcing rib plate 4. The reinforcing rib plate 4 is constructed as an angular structure. One of the outer edges of the reinforcing rib plate 4 is connected to the front side plate 11, and the other outer edge of the reinforcing rib plate 4 is connected to the bottom support plate 14.
