Description

A wiring device for a simulated cockpit sound module Technical Field

[0001] This invention relates to the field of wiring harness installation technology, specifically to a wiring device for a simulated cockpit sound module. Background Technology

[0002] As core equipment for various operational training and simulation experiences, simulators (such as flight simulators and vehicle simulators) rely heavily on their sound modules. The sound module is a crucial component for ensuring immersive simulation, responsible for reproducing various sound signals from real-world scenarios. It works in conjunction with motion and visual systems to provide users with a lifelike sensory experience. The core functionality of the sound module depends on the wiring harness connections between the internal circuit board and external components such as speakers and the control unit. The accuracy and stability of the wiring directly determine the signal transmission quality of the sound module, thus affecting the overall simulation effect and reliability of the simulator.

[0003] Currently, the audio modules in simulated cockpits are mostly integrated into the confined space inside the cockpit, and their circuit boards are usually installed in concealed locations such as gaps in the cockpit shell or equipment compartments. This extremely limited space for wiring operations presents numerous challenges for the laying, splicing, and soldering of the wiring harnesses. Furthermore, the audio module wiring harnesses are mostly precision audio harnesses, which are susceptible to interference during transmission. The harnesses themselves must be kept neat and tidy to avoid tangling or damage; otherwise, audio signal distortion and transmission interruptions may occur, further increasing the difficulty of wiring operations.

[0004] In existing technologies, wiring the circuit board of a simulated cockpit sound module is typically done manually by hand, requiring operators to reach into a confined space to manually pull the wires to the wiring position on the circuit board and complete the soldering. This traditional wiring method has several inherent drawbacks: First, the limited hand movement in the confined space makes it difficult for operators to accurately control the position and orientation of the wire ends, easily leading to wire misalignment, soldering deviations, and other problems. This not only affects wiring efficiency but may also cause sound module malfunctions or even damage to the precision circuit board and wires due to improper soldering. Second, manual hand operation makes it difficult to maintain the stability of the wire ends for extended periods, and hand tremors during soldering can easily cause incomplete soldering or detachment, increasing subsequent maintenance costs. Summary of the Invention

[0005] This invention provides a wiring device for a sound module in a simulated cockpit, to solve the problem of inconvenient wiring of the circuit board of the sound module in a confined space.

[0006] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0007] A wiring device for a simulated cockpit sound module includes an extension mechanism. The extension mechanism includes a spool with a wire roller installed inside. A handle is mounted on the outer wall of the spool. A telescopic cylinder assembly communicates with the side wall of the spool. The telescopic cylinder assembly includes multiple nested and slidably arranged cylinders, one of which is fixedly connected to the spool, while the remaining spools are slidably arranged. The end of the wire harness on the wire roller is fixed to the outermost cylinder, so that when the telescopic cylinder assembly extends, it can pull the end of the wire harness to the wiring position. The device also includes a fixing mechanism, which comprises two hemispherical shells and two... The hemispherical shells are symmetrically mounted on the fixedly arranged cylindrical body. A fixing ring is sleeved on both hemispherical shells. The fixing ring can swing around the center of the sphere formed by the two hemispherical shells. Multiple struts are hinged to the outer wall of the fixing ring. When the multiple struts swing away from the fixing ring, they can contact an external object to fix the fixing ring. When the fixing ring swings relative to the hemispherical shells, the end orientation of the telescopic cylinder assembly can change. When the two hemispherical shells move away from each other, they can apply pressure to the inner wall of the fixing ring, so that the fixing ring can be locked to the hemispherical shells.

[0008] Furthermore, a toothed ring is rotatably connected to the fixed ring, and gears that mesh with the toothed ring are fixedly connected to the hinge shafts of the plurality of support rods. When the toothed ring rotates, it can drive the gears to rotate, so that the support rods can swing on the fixed ring.

[0009] Furthermore, a pawl is installed on the end face of the fixing ring, and the pawl abuts against the teeth of the toothed ring.

[0010] Furthermore, two symmetrically arranged first electric telescopic rods are fixedly connected to the cylindrical body, and the output ends of the two first electric telescopic rods are respectively fixedly connected to the two hemispherical shells.

[0011] Furthermore, a rod is fixedly connected inside the spool, the rod is inserted into the spool, and a cap is threadedly connected to the end of the spool.

[0012] Furthermore, two wire feeding wheels are symmetrically rotatably connected inside the cylinder near the spool, and a power wheel is rotatably connected at the port of the cylinder. The power wheel on the outer cylinder is in contact with the outer wall of the inner cylinder. When the power wheel rotates, it can drive the inner cylinder to extend, thereby extending the telescopic cylinder assembly.

[0013] Furthermore, a wire clamping mechanism is installed on the outermost end of the telescopic cylinder assembly. The wire clamping mechanism includes brackets symmetrically slidably connected to both sides of the end of the cylinder. Each of the two brackets is rotatably connected to a wire clamping wheel, and each of the two brackets is fixedly connected to a rack. A drive tooth is rotatably connected to the cylinder and meshes with the two symmetrical racks. When the drive tooth rotates, it can drive the two wire clamping wheels to move closer to each other to clamp the end of the wire bundle. After the two wire clamping wheels clamp the wire bundle, the telescopic cylinder assembly extends to pull the wire bundle out of the wire roller.

[0014] Furthermore, there are two sets of drive teeth and racks, which are radially symmetrically arranged on both sides of the cylinder.

[0015] Furthermore, it also includes a welding mechanism, which includes a second electric telescopic rod fixedly connected to the outermost end of the cylinder. The output end of the second electric telescopic rod is fixedly connected to a mounting block. Welding heads and straight telescopic rods are fixedly connected to both ends of the mounting block, respectively. A wire pressing block is fixedly connected to the end of the straight telescopic rod. A spring is connected between the wire pressing block and the straight telescopic rod. When the second electric telescopic rod is shortened, the wire pressing block can apply pressure to the end of the wire harness, thereby causing the end of the wire harness to tilt and contact the circuit board. When the second electric telescopic rod continues to shorten, the straight telescopic rod shortens, and the welding head contacts the end of the wire harness.

[0016] Furthermore, the welding mechanism also includes a third electric telescopic rod installed on the opposite side of the second electric telescopic rod. The output end of the third electric telescopic rod is fixedly connected to a wire cutter. After the wire harness is welded to the circuit board, the extension of the third electric telescopic rod enables the wire cutter to cut the wire harness.

[0017] The beneficial effects of this invention are analyzed as follows: A wiring device for a simulated cockpit sound module includes an extension mechanism, which includes a spool, a wire roller installed inside the spool, a handle installed on the outer wall of the spool, and a telescopic cylinder assembly connected to the side wall of the spool. The telescopic cylinder assembly includes multiple nested and slidably arranged cylinders, one of which is fixedly connected to the spool, while the other spools are slidably arranged. The end of the wire bundle on the wire roller is fixed to the outermost cylinder, so that when the telescopic cylinder assembly extends, the end of the wire bundle can be pulled out to the wiring position; it also includes a fixing mechanism. It includes two hemispherical shells, which are symmetrically mounted on a fixed cylindrical body. A fixing ring is fitted onto both hemispherical shells. The fixing ring can swing around the center of the sphere formed by the two hemispherical shells. Multiple struts are hinged to the outer wall of the fixing ring. When the struts swing away from the fixing ring, they can contact an external object to fix the fixing ring. When the fixing ring swings relative to the hemispherical shells, the end orientation of the telescopic cylinder assembly can change. When the two hemispherical shells move away from each other, they can apply pressure to the inner wall of the fixing ring, so that the fixing ring can be locked to the hemispherical shells.

[0018] After the wire harness is fixed, align the extended end of the telescopic cylinder assembly of the device with the wiring position of the circuit board to be wired. Then, control the telescopic cylinder assembly to extend. At this time, the wire harness wound on the wire roller is released as the telescopic cylinder assembly extends until the end of the wire harness reaches the wiring position. After adjusting the telescopic cylinder assembly to a suitable length, control multiple support rods to swing away from the fixing ring, so that multiple support rods can contact the inner wall of the wiring gap. After the multiple support rods are opened and contact the inner wall of the gap, the fixing ring is fixed. At this time, the two hemispherical shells can be controlled to rotate in the middle of the fixing ring by holding the handle, so that the orientation of the end of the cylinder can be further fine-tuned. After adjusting the orientation of the cylinder end to align with the soldering position of the circuit board, control the two hemispherical shells to move away from each other, so that the pressure between the two hemispherical shells and the fixing ring increases, and the static friction between the fixing ring and the hemispherical shells increases, making it difficult for the hemispherical shells to rotate relative to the fixing ring. At this time, the orientation of the telescopic cylinder assembly is fixed, thus ensuring that the wire harness can be accurately soldered to the circuit board. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As shown in Figures 1-8, an embodiment of a simulated cockpit sound module wiring device includes an extension mechanism 100, which includes a wire spool 110. A wire roller 130 is installed inside the wire spool 110, and a handle 112 is installed on the outer wall of the wire spool 110. A telescopic cylinder assembly is connected to the side wall of the wire spool 110. The telescopic cylinder assembly includes multiple nested and slidably arranged cylinders 140, one of which is fixedly connected to the wire spool 110, while the remaining wire spools 110 are slidably arranged. The end of the wire harness on the wire roller 130 is fixed to the outermost cylinder 140, so that when the telescopic cylinder assembly extends, the end of the wire harness can be pulled out to the wiring position. The device also includes a fixing mechanism 400, which includes two... Two hemispherical shells 420 are symmetrically mounted on a fixedly positioned cylindrical body 140. A fixing ring 430 is sleeved on both hemispherical shells 420. The fixing ring 430 can swing around the center of the sphere formed by the two hemispherical shells 420. Multiple struts 440 are hinged to the outer wall of the fixing ring 430. When the multiple struts 440 swing away from the fixing ring 430, they can contact an external object to fix the fixing ring 430. When the fixing ring 430 swings relative to the hemispherical shells 420, the end orientation of the telescopic cylinder assembly can change. When the two hemispherical shells 420 move away from each other, they can apply pressure to the inner wall of the fixing ring 430, so that the fixing ring 430 can be locked to the hemispherical shells 420.

[0023] The working mechanism of the simulated cockpit sound module wiring device provided in this embodiment is as follows: When wiring the sound module circuit board in a confined space, the wire roller 130 with the wire harness wound around it is first installed inside the wire drum 110. At this time, the telescopic drum assembly is in its shortest state. The wire harness on the wire roller 130 is pulled out, so that the end of the wire harness passes through the interior of multiple drums 140, so that the end of the wire harness is fixed at the end of the innermost drum 140 and extends out a certain distance. The wire insulation of the extended part of the wire harness is manually stripped off to expose the wire core. Among them, the innermost drum 140 of the telescopic drum assembly is at the end when the telescopic drum assembly is extended. This end is closest to the circuit board in the subsequent wiring process. After the wire harness is fixed, the extended end of the telescopic drum assembly of the device is aligned with the wiring position of the circuit board to be wired. Then, the telescopic drum assembly is controlled to extend. At this time, the wire harness wound on the wire roller 130 is released as the telescopic drum assembly extends until the end of the wire harness reaches the end of the circuit board. At the wiring position, after adjusting the telescopic cylinder assembly to the appropriate length, control the multiple support rods 440 to swing away from the fixing ring 430, so that the multiple support rods 440 can contact the inner wall of the wiring gap. After the multiple support rods 440 are spread out and in contact with the inner wall of the gap, the fixing ring 430 is fixed. At this time, the ball formed by the two hemispherical shells 420 can be controlled to rotate in the middle of the fixing ring 430 by holding the handle 112, so that the orientation of the end cylinder 140 can be further fine-tuned. After adjusting the orientation of the end of the cylinder 140 to align with the soldering position of the circuit board, control the two hemispherical shells 420 to move away from each other, so that the pressure between the two hemispherical shells 420 and the fixing ring 430 increases, and the static friction between the fixing ring 430 and the hemispherical shells 420 increases, making it difficult for the hemispherical shells 420 to rotate relative to the fixing ring 430. At this time, the orientation of the telescopic cylinder assembly is fixed, thus ensuring that the wire harness can be accurately soldered to the circuit board.

[0024] In the optional embodiments of this example, a more preferred method is to rotatably connect a toothed ring 460 to the fixed ring 430, and fix a gear 450 that meshes with the toothed ring 460 to the hinge shaft of each of the multiple support rods 440. When the toothed ring 460 rotates, it can drive the gear 450 to rotate, so that the support rod 440 can swing around the fixed ring 430.

[0025] The toothed ring 460 and the fixed ring 430 are coaxially rotatably connected. After adjusting the device to a suitable position, manually rotating the toothed ring 460 causes the toothed ring 460 to drive multiple gears 450 to rotate synchronously, thereby allowing multiple support rods 440 to swing. At this time, the multiple support rods 440 simultaneously unfold and support the inner wall of the gap, thereby completing the position restriction of the fixed ring 430. This allows the device to swing around the center of the fixed ring 430 as a fulcrum to adjust the end position of the wire harness.

[0026] In the optional embodiments of this example, a preferred embodiment is that a pawl 470 is installed on the end face of the fixing ring 430, and the pawl 470 abuts against the teeth of the toothed ring 460.

[0027] The pawl 470 is designed to allow the toothed ring 460 to rotate in one direction. When the toothed ring 460 rotates and the multiple struts 440 are extended, the teeth of the toothed ring 460 can push the pawl 470 to swing. Conversely, they cannot. After the wire harness welding is completed, the pawl 470 can be manually moved away from the toothed ring 460, and then the toothed ring 460 can be rotated in the opposite direction to make the multiple struts 440 close.

[0028] In the optional mode of this embodiment, the more preferred mode is: two symmetrically arranged first electric telescopic rods 410 are fixedly connected to the fixedly arranged cylinder 140, and the output ends of the two first electric telescopic rods 410 are respectively fixedly connected to the two hemispherical shells 420.

[0029] The output ends of the two first electric telescopic rods 410 are respectively connected to the two hemispherical shells 420. In the initial state, the two first electric telescopic rods 410 are in the shortened state. At this time, the pressure between the two hemispherical shells 420 and the inner wall of the fixing ring 430 is small. When the fixing ring 430 is fixed in a suitable position, the two first electric telescopic rods 410 are extended, so that the two hemispherical shells 420 move away from each other. At this time, the pressure between the two hemispherical shells 420 and the fixing ring 430 increases, so that the fixing ring 430 no longer moves relative to the hemispherical shells 420. A switch for controlling the extension and retraction of the first electric telescopic rods 410 is provided on the handle 112 for easy operation and control by the operator.

[0030] In the optional embodiments of this example, the preferred method is as follows: a rod 120 is fixedly connected inside the spool 110, the rod 120 is inserted into the spool 130, and a spool cap 111 is threadedly connected to the end of the spool 110.

[0031] The inside of the spool 110 is hollow, which facilitates the placement of the wire roller 130. The wire roller 130 has a hole in the middle. The hole in the middle of the wire roller 130 is fitted onto the insertion rod 120, so that the wire roller 130 can rotate on the insertion rod 120 when the subsequent wire bundle is released. After the wire roller 130 is installed in the spool 110, the spool cover 111 is tightened to complete the installation of the wire roller 130.

[0032] In the optional embodiments of this example, the preferred method is as follows: two wire feeding wheels 480 are symmetrically rotatably connected inside the cylinder 140 near the wire spool 110, and a power wheel 141 is rotatably connected at the port of the cylinder 140. The power wheel 141 on the outer cylinder 140 is in contact with the outer wall of the inner cylinder 140. When the power wheel 141 rotates, it can drive the inner cylinder 140 to extend, thereby extending the telescopic cylinder assembly.

[0033] The two wire feed rollers 480 can be driven to rotate by small motors. Similarly, the switches controlling these two small motors are also located on the handle 112 for easy operator control. The drive roller 141 is also driven to rotate by a small motor, and the switch controlling the rotation of the drive roller 141 is also located on the handle 112. When controlling the extension and retraction of the telescopic cylinder assembly, the drive roller 141 is rotated via the switch on the handle 112. At this time, the rotation of the drive roller 141 relies on the friction between it and the outer wall of the inner cylinder 140 to drive the inner cylinder. Body 140 slides relative to the outer cylinder 140, thereby causing the telescopic cylinder assembly to extend and retract. Outside the outermost cylinder 140, the remaining cylinders 140 are equipped with drive wheels 141. The multiple drive wheels 141 can be controlled to rotate synchronously in the forward or reverse direction by the switch on the handle 112, so that the relative sliding distance between the multiple cylinders 140 is equal. In addition, when the multiple drive wheels 141 rotate and the telescopic cylinder assembly extends, the wire feeding wheel 480 also rotates synchronously, thereby ensuring that the wire harness can be stably released when the telescopic cylinder assembly extends.

[0034] In the optional embodiments of this example, a preferred method is to install a wire clamping mechanism 200 on the outermost cylindrical body 140 of the telescopic cylinder assembly. The wire clamping mechanism 200 includes brackets 210 symmetrically slidably connected to both sides of the end of the cylindrical body 140. Each bracket 210 is rotatably connected to a wire clamping wheel 240, and each bracket 210 is fixedly connected to a rack 220. A drive tooth 230 is rotatably connected to the cylindrical body 140 and meshes with the two symmetrical racks 220. When the drive tooth 230 rotates, it can drive the two wire clamping wheels 240 to move closer to each other to clamp the end of the wire bundle. After the two wire clamping wheels 240 clamp the wire bundle, the telescopic cylinder assembly can extend to pull out the wire bundle on the wire roller 130.

[0035] The wire clamping mechanism 200 allows the end of the wire harness to be fixed on the outermost cylinder 140. After the wire harness is manually pulled out to a suitable length, it is positioned between the two clamping wheels 240. Then, the drive gear 230 is rotated, causing the two symmetrically arranged racks 220 to move closer together. This causes the two supports 210 connected to the racks 220 to move closer together, and the two clamping wheels 240 mounted on the two supports 210 to move closer together, clamping the end of the wire harness. The drive gear 230 is also driven to rotate by a small motor. The switch for this small motor is mounted on the handle 112. The drive gear 230 is rotated by controlling the switch on the handle 112. In addition, the small motor used to drive the drive gear 230 has a self-locking function. When the small motor of the drive gear 230 stops running, the drive gear 230 will not reverse or rotate further, thus ensuring that the wire harness is firmly clamped.

[0036] In the optional embodiments of this example, the preferred method is that there are two sets of drive teeth 230 and rack 220, and the two sets of drive teeth 230 and rack 220 are radially symmetrically arranged on both sides of the cylinder 140.

[0037] The arrangement of two sets of drive teeth 230 and rack 220 ensures that the driving force of the two supports 210 approaching each other is balanced, thereby ensuring that the two clamping wheels 240 can firmly clamp the wire harness.

[0038] In the optional embodiments of this example, a preferred method is to further include a welding mechanism 300. The welding mechanism 300 includes a second electric telescopic rod 310 fixedly connected to the outermost cylindrical body 140. The output end of the second electric telescopic rod 310 is fixedly connected to a mounting block 320. The two ends of the mounting block 320 are respectively fixedly connected to a welding head 330 and a straight telescopic rod 340. The end of the straight telescopic rod 340 is fixedly connected to a wire pressing block 350. A spring 351 is connected between the wire pressing block 350 and the straight telescopic rod 340. When the second electric telescopic rod 310 is shortened, the wire pressing block 350 can apply pressure to the end of the wire harness, thereby causing the end of the wire harness to tilt and contact the circuit board. When the second electric telescopic rod 310 continues to shorten, the straight telescopic rod 340 shortens, and the welding head 330 contacts the end of the wire harness.

[0039] The welding head 330 is electrically heated and pre-applied with solder. After the wire harness installation position is adjusted, the second electric telescopic rod 310 is shortened. The length of the straight telescopic rod 340 is higher than the welding head 330, meaning the wire clamping block 350 is below the welding head 330. Thus, when the second electric telescopic rod 310 shortens, it drives the mounting block 320 downwards. At this point, the wire clamping block 350 first contacts the wire harness and bends its end, allowing the end of the wire harness to approach and contact the circuit board. As the second electric telescopic rod 310 continues to shorten, the length of the straight telescopic rod 340 decreases, and the welding head 330 continues to move downwards to contact the end of the wire harness, welding it to the circuit board. After the wire harness welding is completed, the second electric telescopic rod 310 is extended, causing the welding head 330 and the wire clamping block to... 350 is moved away from the wire harness, and then the wire feed wheel 480 and the wire clamping wheel 240 are rotated to further release the wire harness. When the wire harness is released, the device can be released from its fixed state, and then the entire device can be pulled out from the installation gap. At the same time, the wire harness that is soldered to the circuit board at one end is also released. After the wire harness is released to a suitable length, it is manually cut. At this time, one end of the wire harness is installed on the circuit board of the sound module, and the other end is led out for subsequent external wiring installation. A small motor for driving the rotation of the wire clamping wheel 240 is installed on the bracket 210. The control switch of this small motor is installed on the handle 112. By controlling the rotation of the wire clamping wheel 240, the release of the wire harness on the wire roller 130 does not require pulling force, thereby preventing the end of the wire harness soldered to the circuit board from being pulled off.

[0040] In the optional embodiments of this example, the welding mechanism 300 further includes a third electric telescopic rod 360 installed on the opposite side of the second electric telescopic rod 310. The output end of the third electric telescopic rod 360 is fixedly connected to a wire cutter 370. After the wire harness is welded to the circuit board, the extension of the third electric telescopic rod 360 enables the wire cutter 370 to cut the wire harness.

[0041] After the wiring harness is installed, if it needs to be cut, the third electric telescopic rod 360 is extended. At this time, the wire clamping block 350 supports the upper part of the wiring harness, and the wire cutter 370 moves upward to cut the wiring harness. The second electric telescopic rod 310 and the third electric telescopic rod 360 are also equipped with control switches. The two sets of switches controlling these two electric telescopic rods are located on the handle 112 for easy control by the operator.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
