[0034] 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 the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0035] Reference Figures 1 to 5 As shown, an embodiment of the present invention provides a horizontal telescopic transport device for use in an acoustic test box, comprising a support assembly 100 , a tooling plate 200 , a cylinder 300 and a telescopic assembly 400 .

[0036] The support assembly 100 is connected to the acoustic test chamber and includes four legs 110 and a platform 120 fixedly connected to the tops of the legs 110. The cylinder 300 is connected to the top of the platform 120. A through hole 121 is defined in the platform 120, through which the piping for the cylinder 300 (not shown) passes to the bottom of the platform 120.

[0037] The tooling plate 200 is disposed at one end of the support assembly 100 .

[0038] The cylinder 300 is connected to the support assembly 100 .

[0039] The telescopic assembly 400 includes an intermediate connector 410, a first telescopic section 420, a second telescopic section 430, and two connecting clamps 440. The intermediate connector 410 is connected to the telescopic end of the cylinder 300. The first telescopic section 420 and the second telescopic section 430 are located at the top and bottom of the intermediate connector 410, respectively. The first telescopic section 420 is slidably connected to the support assembly 100. The second telescopic section 430 includes a first transmission pulley 431, a second transmission pulley 432, and a belt 433. The belt 433 is wound around the first and second transmission pulleys 431, 432. The first and second transmission pulleys 431, 432 are rotatably connected to the ends of the intermediate connector 410, respectively. The belts 433, located at the top and bottom of the first transmission pulley 431, are connected to the tooling plate 200 and the support assembly 100, respectively, via connecting clamps 440. The tooling plate 200 is slidably connected to the intermediate connector 410.

[0040] The telescopic end of the cylinder 300 is telescoped, thereby driving the tooling plate 200 and the intermediate connecting member 410 to telescope relative to the support assembly 100, thereby realizing the first stage of telescoping; at the same time, when the intermediate connecting member 410 is telescoping, since the tooling plate 200 and the support assembly 100 are respectively connected to the belt 433 through the connecting clamp 440, and since the support assembly 100 is fixed, the belt 433 drives the first transmission wheel 431 and the second transmission wheel 432, thereby driving the tooling plate 200 at the other end to perform the second stage of telescoping relative to the intermediate connecting member 410.

[0041] Specifically, this embodiment achieves two-stage telescopic expansion and contraction through the coordination of a single cylinder 300, a first telescopic portion 420, and a second telescopic portion 430. Thus, this application utilizes a single cylinder 300 to achieve long-range transport, reducing the risk of cylinder 300 leaks, thereby lowering background noise and ensuring acoustic test results. It also reduces the probability of failure and simplifies the maintenance process.

[0042] Furthermore, there are two telescopic assemblies 400 , which are symmetrically arranged on both sides of the cylinder 300 .

[0043] Specifically, the two telescopic assemblies 400 provided in this embodiment enable the two-stage telescopic movement of the tooling plate 200 to be smoother, more stable and reliable.

[0044] Furthermore, the present application includes a control system (not shown in the figure); the control system is electrically connected to the cylinder 300.

[0045] Specifically, in this embodiment, the extension and retraction of the tooling plate 200 can be controlled by a control system to achieve full automation.

[0046] Furthermore, the present application also includes a limit assembly 500, which is arranged in a one-to-one correspondence with the telescopic assembly 400. The limit assembly 500 includes two limit sensors 510, which are respectively arranged at both ends of the support assembly 100 and are used to monitor the travel of the end of the intermediate connector 410 away from the telescopic end of the cylinder 300. The limit sensors 510 are electrically connected to the control system. The limit sensors 510 are contact sensors; a trigger member 520 is provided at one end of the intermediate connector 410, located between the two limit sensors 510, and the trigger member 520 cooperates with the contact sensor.

[0047] Specifically, the present embodiment provides a limit assembly 500 , so as to identify the telescopic stroke of the intermediate connector 410 , thereby preventing the intermediate connector 410 from being excessively extended or retracted, thereby being disengaged from the support assembly 100 .

[0048] Furthermore, the first telescopic portion 420 is connected to the bottom of the intermediate connection member 410 , and the second telescopic portion 430 is connected to the top of the intermediate connection member 410 .

[0049] Specifically, in this embodiment, the second telescopic portion 430 connected to the tooling plate 200 is located at the top of the intermediate connector 410, and the first telescopic portion 420 is located at the bottom of the intermediate connector 410. This prevents interference with other components when the tooling plate 200 performs two-stage telescopic movement, effectively utilizing space, and also facilitates placing other components to be transported on top of the tooling plate 200.

[0050] Furthermore, the first telescopic portion 420 includes a first rail 421 and at least one first slider 422; the first rail 421 is connected to the bottom of the intermediate connector 410, the first slider 422 cooperates with the first rail 421, and the first slider 422 is connected to the support assembly 100. The second telescopic portion 430 also includes a second rail 434 and at least one second slider 435; the second rail 434 is connected to the top of the intermediate connector 410, the second slider 435 cooperates with the second rail 434, and the second slider 435 is connected to the tooling plate 200.

[0051] Specifically, the first telescopic portion 420 and the second telescopic portion 430 are both slidably connected by means of a slider and a track, and the structure is stable and reliable.

[0052] Furthermore, a waist-shaped hole 411 extending along the moving direction of the intermediate connecting member 410 is provided at the end of the intermediate connecting member 410 ; the first transmission wheel 431 and the second transmission wheel 432 are connected to the waist-shaped hole 411 by bolts.

[0053] Specifically, the waist-shaped hole 411 is provided in this embodiment, so as to facilitate adjustment of the distance between the first transmission wheel 431 and the second transmission wheel 432 , thereby facilitating adjustment of the tension of the belt 433 .

[0054] In some embodiments, the belt 433 is gear-engaged with the first transmission wheel 431 and the second transmission wheel 432 .

[0055] Furthermore, the present application also includes a drag chain 600 provided on one side of the support assembly 100. The air pipes and lines of the tooling board 200 are passed through the drag chain 600, thereby preventing the air pipes and lines on the tooling board 200 from getting entangled when the tooling board 200 moves.

[0056] The present invention has a simple structure, compact design, high operational reliability and stability, and low cost. The present invention can solve the problems of using multiple cylinders 300, which may cause air leakage, affect acoustic test results, and be prone to failure and difficult to repair.

[0057] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
