[0041] Please see Figures 1 to 5 As shown, an electrical test bench corresponding to a preferred embodiment of this utility model includes: a cabinet 100, including a test cavity 110 and an electrical cavity 120 arranged adjacent to the test cavity 110; a drawer assembly 200 for carrying the product to be tested, which is movably connected to the cabinet 100 and adapted to be pushed into or pulled out of the test cavity 110; an electrical system 300 housed in the electrical cavity 120, which includes a cable structure 310 extending from the electrical cavity 120 into the test cavity 110; and a spring balancer 400 disposed on the top of the test cavity 110, with the cable structure 310 suspended at the telescopic end of the spring balancer 400 and its free end extending to the drawer assembly 200; wherein, the drawer assembly 200 is provided with a connecting structure, the free end of the cable structure 310 is adapted to connect with the connecting structure or the product to be tested, and the telescopic end of the spring balancer 400 responds to the pulling of the drawer assembly 200 to drive the cable structure 310 to move up and down. In this embodiment, the product is specifically a driver.

[0042] This invention, by setting up a test chamber 110 and a drawer assembly 200 to support the product under test, allows the test chamber 110 to be pushed in or pulled out, facilitating the simulation of the actual working environment temperature of the product during testing and improving test accuracy. A spring balancer 400 is installed at the top of the test chamber 110. The cable structure 310 of the electrical system 300 extends into the test chamber 110 and is suspended at the telescopic end of the spring balancer 400. The free end of the cable structure 310 extends to the drawer assembly 200, and is suitable for connection with the product. The telescopic end of the spring balancer 400 responds to the drawer assembly 200. The pull-out mechanism of the cable structure 310 causes it to move up and down, ensuring that the cable structure 310 is always suspended, improving the cleanliness of the test chamber 110 and preventing the cable structure 310 from obstructing the drawer assembly 200, thus facilitating the pulling out of the drawer assembly 200 and the loading and unloading of products. In addition, the drawer assembly 200 is provided with a connecting structure. When the drawer assembly 200 is in an empty state, the free end of the cable structure 310 can be connected to the connecting structure, so that when the drawer assembly 200 is pulled out of the test chamber 110, the free end of the cable structure 310 moves out synchronously with it, making it easier for the products loaded onto the drawer assembly 200 to connect with the free end.

[0043] Furthermore, the cable structure 310 includes a clamping plate 311 and a plurality of cables 312. The clamping plate 311 has a plurality of cable routing holes 3111 arranged side-by-side. The inner diameter of each cable routing hole 3111 matches the outer diameter of the cables 312. The cables 312 are fixedly threaded through different cable routing holes 3111 to ensure orderly arrangement and prevent tangling. In this embodiment, there are at least two clamping plates 311. One clamping plate 311 is connected to the telescopic end of the spring balancer 400, allowing the cables 312 to be suspended from the spring balancer 400. The other clamping plate 311 is located near the free end of the cable structure 310, facilitating connection or disconnection of the free end of the cables 312 from the product. Preferably, the clamping plate 311 connected to the spring balancer 400 is located near the middle of the cables 312, ensuring stability during suspension and effectively preventing the cables 312 from falling onto the drawer assembly 200 during the telescopic process of the spring balancer 400.

[0044] Furthermore, the cabinet 100 has an opening on its front side. The drawer assembly 200 is inserted into the test chamber 110 through this opening. The drawer assembly 200 can be pushed to the testing position and close the opening, so that the product located on the drawer assembly 200 is received in the test chamber 110. The drawer assembly 200 can also be pulled out of the cabinet 100 from the opening and is in a pick-up / placement position for product retrieval. The drawer assembly 200 includes a drawer 210 and a fixture 220. The drawer 210 is movably connected to the cabinet 100 and can slide along the front-back direction of the cabinet 100 to be in a testing position or a pick-up / placement position. The fixture 220 is detachably disposed in the drawer 210. The fixture 220 has at least one positioning groove 221 recessed inward from its top surface to support and position the product. One or more positioning grooves 221 can be provided as needed to adapt to different types of products.

[0045] The connecting structure is set on the fixture 220 or the drawer 210. In this embodiment, a hook structure is preferred, which is simple in structure and easy to assemble and disassemble with the cable structure 310. When the fixture 220 is not holding the product, the cable structure 310 can be directly hung on the connecting structure through the cable clamp 311 to prevent the cable structure 310 from being stuck in the test cavity 110 when the drawer 210 is pulled out of the cabinet 100.

[0046] Preferably, a limit switch 500 is provided inside the test chamber 110. When the drawer 210 is in the test position, the limit switch 500 is adapted to detect the drawer 210 and send a power supply signal to supply power to the product. When the drawer 210 is not in the second position, the limit switch 500 does not detect the drawer 210 and sends a power-off signal to cut off power to the product, thereby ensuring safety during the test process. In addition, multiple drawer assemblies 200 are arranged side by side along the left and right direction of the cabinet 100. The spring balancer 400 and the cable structure 310 correspond one-to-one with the drawer assembly 200, so that the test bench can test multiple products simultaneously, improving test efficiency.

[0047] Furthermore, the cabinet 100 includes a frame 130, a sealing plate 140, and a first cabinet door 150. A drawer assembly 200 is movably disposed on the front side of the frame 130. Several sealing plates 140 are disposed on the frame 130. The first cabinet door 150 is disposed on the front side of the frame 130. The drawer assembly 200, the first cabinet door 150, and part of the sealing plate 140 cooperate to form a testing chamber 110. The first cabinet door 150 can move relative to the frame 130 to open or close the testing chamber 110. By adopting the above structure, when the testing chamber 110 encounters an emergency, the operator can open the first cabinet door 150 to directly reach into the testing chamber 110 to perform corresponding operations, and it also facilitates the disassembly and assembly of the various components of the testing chamber 110. In this embodiment, the first cabinet door 150 is located above the drawer assembly 200 and is provided with a transparent viewing window 151. The viewing range of the viewing window 151 covers the drawer assembly 200 and the cable structure 310, which facilitates the operator to observe the internal condition of the test chamber 110 during the test.

[0048] The test chamber 110 and the electrical chamber 120 are distributed along the front and rear direction of the cabinet 100. A second cabinet door 160 is provided on the rear side of the frame 130. The second cabinet door 160 and part of the sealing plate 140 cooperate to form the electrical chamber 120. The second cabinet door 160 can move relative to the frame 130 to open or close the electrical chamber 120, thereby facilitating the disassembly, assembly and maintenance of the electrical system 300.

[0049] In addition, part of the sealing plate 140 also forms a motor cavity 170, which is arranged adjacent to the test cavity 110 and the electrical cavity 120 below. The electrical test bench also includes a test motor 600 housed in the motor cavity 170, and the test motor 600 is electrically connected to the electrical system 300 via wires. With the test cavity 110, electrical cavity 120 and motor cavity 170 arranged in the above manner, the internal structure of the cabinet 100 is compact, and the disassembly, assembly and maintenance of the various components inside the cabinet 100 are very convenient.

[0050] Because the test chamber 110 needs to simulate the working environment of the product, the temperature inside the test chamber 110 is relatively high. Preferably, the sealing plate 140 corresponding to the test chamber 110 is provided with thermal insulation material. The test chamber 110 and the electrical cavity 120, as well as the test chamber 110 and the motor cavity 170, are all separated by thermal insulation material. On the one hand, this can keep the test chamber 110 warm, so that the internal temperature of the test chamber 110 is relatively stable. On the other hand, it can also prevent the temperature of the test chamber 110 from being transferred to the electrical cavity 120 and the motor cavity 170, and prevent the electrical system 300 and / or the test motor 600 from being damaged due to overheating.

[0051] Furthermore, the electrical test bench also includes a universal bracket 700 and a control panel 800. The universal bracket 700 is connected to the outside of the cabinet 100, and the control panel 800 is connected to the electrical system 300 via signal. Operators can perform corresponding operations on the test bench through the control panel 800. At the same time, various test information generated by the test bench will also be displayed on the control panel 800 for real-time observation of the operating status. The control panel 800 is connected to the universal bracket 700 for omnidirectional adjustment of its position, facilitating operation and observation by operators.

[0052] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
