[0002] The instrument panel tube beam assembly is an important component of the vehicle, serving as a bridge between the instrument panel module and the vehicle body. To ensure that the various instruments and components it supports can function properly under high-speed driving and vibration conditions, the instrument panel tube beam must have sufficient rigidity.

[0003] After searching, the utility model with Chinese patent announcement number CN113978560B discloses a passenger car instrument panel crossbeam assembly structure, including a tube beam and two cylinders fixed on a welding jig. Both ends of the tube beam are provided with process holes, and the piston rods of the two cylinders are provided with positioning devices. The two positioning devices are respectively plugged into the two process holes. A bracket is fixed on the tube beam, and the bracket is provided with an arc-shaped overlap that fits the outer wall of the tube beam.

[0004] When the above-mentioned tube beam assembly is in use, in order to reduce the impact of external forces on the driver and co-driver in the event of an accident, the instrument panel tube beam is also required to have good energy absorption. Therefore, it is particularly important to perform anti-collision testing on the instrument panel tube beam assembly. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-collision detection device for an instrument panel tube beam assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-collision detection device for an instrument panel tube beam assembly, comprising a mounting seat, two angle codes fixedly mounted on the outer walls at both ends of the mounting seat, a support frame fixedly connected to one side of the top outer wall of the mounting seat, an impact assembly mounted on the top of the support frame, the impact assembly comprising a mounting shaft rotatably connected inside the support frame, the mounting shaft being arranged in a horizontal state, a knocking rod fixedly connected to one side of the circumferential outer wall of the mounting shaft, and a counterweight block fixedly connected to one end of the knocking rod.

[0007] As a further preferred embodiment of the present technical solution, a driven gear and a transmission gear that mesh with each other are rotatably connected to the top of the outer wall of one end of the support frame, and the driven gear is coaxially fixed to one end of the mounting shaft.

[0008] The force of impacting the pipe beam can be adjusted as needed to simulate the degree of damage to the pipe beam under different circumstances, so as to intuitively observe whether the quality of the pipe beam is qualified. The transmission gear is driven to rotate on the outside of the support frame through the handle. The transmission gear drives the driven gear to rotate through engagement. The installation shaft will rotate synchronously with the driven gear, and the external knocking rod is gradually driven to change to a horizontal state. The potential energy of the counterweight block increases. When the restriction of the transmission gear is lost, the potential energy of the counterweight block is converted into kinetic energy until the counterweight block hits the outside of the pipe beam at the bottom. The anti-collision test can be completed, and the purpose of changing the impact force of the counterweight block can be achieved by adjusting the inclination angle of the knocking rod, thereby meeting different experimental needs.

[0009] As a further preferred embodiment of the present technical solution, two limiting grooves 2 are provided on the outer wall at the top of the mounting seat, and two receiving components are installed inside the two limiting grooves 2. The receiving components include the same abutment plate slidably connected to the two limiting grooves 2, and an extension plate is fixedly connected to the outer wall on one side of the abutment plate, and the counterweight block can just pass through the gap between the two extension plates.

[0010] As a further preferred embodiment of the present technical solution, a limiting groove three is provided inside the extension plate, a horizontally arranged screw rod is rotatably connected inside the limiting groove three, a splint is threadedly connected to the outside of the screw rod, and the splints are slidably connected to the inside of the limiting groove three.

By rotating the screw with the knob, the splint sliding inside the limit slot three will be driven by the screw to approach the pipe beam, and stop when the two are in contact, to ensure that the pipe beam will not be displaced due to impact when placed between the splint and the abutment plate. Then the abutment plate is pushed to slide along the inside of the limit slot two, so that the tested part can be hit by the counterweight block, so that pipe beams of different models can be fixed, and since the position of the abutment plate is a movable connection, different positions of the pipe beam can be tested, which is beneficial to increase the adaptability of the device.

[0012] As a further preferred embodiment of the present technical solution, a plurality of vertically arranged reinforcing plates are fixedly connected to the inside of the two abutting plates, and the plurality of reinforcing plates are all arranged in a triangular shape.

[0013] As a further preferred embodiment of the present technical solution, a horizontally arranged limiting groove 1 is provided on the top outer wall of the counterweight block.

[0014] As a further preferred embodiment of the present technical solution, the transmission ratio between the transmission gear and the driven gear is greater than one.

[0015] The utility model provides an instrument panel tube beam assembly anti-collision detection device, which has the following beneficial effects:

[0016] (1) The utility model can adjust the force of impacting the pipe beam as needed by setting an impact component, and can simulate the degree of damage to the pipe beam under different conditions, so as to visually observe whether the quality of the pipe beam is qualified. The handle drives the transmission gear to rotate on the outside of the support frame, and the transmission gear drives the driven gear to rotate through engagement. The installation shaft will rotate synchronously with the driven gear, and the external knocking rod is gradually driven to change to a horizontal state, and the potential energy of the counterweight block increases. When the restriction of the transmission gear is lost, the potential energy of the counterweight block is converted into kinetic energy until the counterweight block hits the outside of the pipe beam at the bottom, and the anti-collision detection can be completed. Moreover, by adjusting the inclination angle of the knocking rod, the purpose of changing the impact force of the counterweight block can be achieved, thereby meeting different experimental needs.

By rotating the screw of the knob belt, the clamping plate sliding in the inner limit groove three will be driven by the screw to approach the pipe beam, and stop when the two are in contact, ensuring that the pipe beam will not be displaced due to impact when placed between the clamping plate and the abutment plate. Then, the abutment plate is pushed to slide along the inner limit groove two, so that the tested part can be hit by the counterweight block, so that pipe beams of different models can be fixed. Moreover, since the position of the abutment plate is a movable connection, different positions of the pipe beam can be tested, which is beneficial to increase the adaptability of the device.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, an anti-collision detection device for an instrument panel tube beam assembly includes a mounting base 1. Two angle codes 4 are fixedly installed on the outer walls at both ends of the mounting base 1, so that the mounting base 1 can be fixed to the ground, which is beneficial to increasing the stability of the mounting base 1. A support frame 2 is fixedly connected to one side of the top outer wall of the mounting base 1, and an impact component 6 is installed on the top of the support frame 2. The impact component 6 includes a mounting shaft 601 that is rotatably connected to the inside of the support frame 2. The mounting shaft 601 is arranged in a horizontal state, and a knocking rod 602 is fixedly connected to one side of the circumferential outer wall of the mounting shaft 601, and a counterweight block 603 is fixedly connected to one end of the knocking rod 602.

[0026] The transmission gear 605 is driven by the handle to rotate on the outside of the support frame 2, and the transmission gear 605 drives the driven gear 604 to rotate through engagement. The installation shaft 601 will rotate synchronously with the driven gear 604, and the knocking rod 602 outside it is gradually driven to change to a horizontal state, and the potential energy of the counterweight block 603 increases. When the restriction of the transmission gear 605 is lost, the potential energy of the counterweight block 603 is converted into kinetic energy until the counterweight block 603 hits the outside of the pipe beam at the bottom, and the anti-collision detection is completed. By adjusting the inclination angle of the knocking rod 602, the purpose of changing the impact force of the counterweight block 603 can be achieved, thereby meeting different experimental needs.

[0027] like Figure 2 and Figure 4 As shown, two limiting grooves 701 are provided on the top outer wall of the mounting seat 1, and two receiving components 7 are installed inside the two limiting grooves 701. The receiving component 7 includes the same abutment plate 702 that is slidably connected to the two limiting grooves 701. An extension plate 703 is fixedly connected to the outer wall on one side of the abutment plate 702, and the counterweight block 603 can just pass through the gap between the two extension plates 703.

A clamping plate 706 is threadedly connected to the outside of the screw rod 705, and the clamping plates 706 are slidably connected to the inside of the limiting groove 3 704.

[0029] The position of the splint 706 is adjusted according to the model of the pipe beam assembly. By rotating the screw rod 705 with the knob, the splint 706 sliding inside the limit slot three 704 will be driven by the screw rod 705 to approach the pipe beam, and stop when the two are in contact, ensuring that the pipe beam will not be displaced due to impact when placed between the splint 706 and the abutment plate 702. Then, the abutment plate 702 is pushed to slide along the inside of the limit slot two 701, so that the tested part can be hit by the counterweight block 603, so that different models of pipe beams can be fixed, and since the position of the abutment plate 702 is a movable connection, different positions of the pipe beam can be tested, which is beneficial to increase the adaptability of the device.

[0032] like Figure 3 As shown, the transmission ratio of the transmission gear 605 to the driven gear 604 is greater than one, and the transmission gear 605 rotates multiple times to drive the driven gear 604 to rotate one circle, making the driving process more labor-saving.

[0033] The utility model provides an instrument panel tube beam assembly anti-collision detection device, the specific working principle is as follows:

[0034] When the device is working, the position of the clamping plate 706 is first adjusted according to the model of the pipe beam assembly, and the screw rod 705 with the knob is rotated. The clamping plate 706 sliding inside the limiting groove 3 704 will be driven by the screw rod 705 to approach the pipe beam, and stop when the two are in contact, ensuring that the pipe beam will not be displaced due to impact when placed between the clamping plate 706 and the abutment plate 702. Then, the abutment plate 702 is pushed to slide along the inside of the limiting groove 2 701, so that the tested part can be hit by the counterweight block 603, so that pipe beams of different models can be fixed, and because the position of the abutment plate 702 is a movable connection, different positions of the pipe beam can be tested, which is beneficial to increasing the device Adaptability, then drive the transmission gear 605 to rotate on the outside of the support frame 2 through the handle, and the transmission gear 605 drives the driven gear 604 to rotate through engagement, and the installation shaft 601 will rotate synchronously with the driven gear 604, and its external knocking rod 602 is gradually driven to change to a horizontal state, and the potential energy of the counterweight block 603 increases. When the restriction of the transmission gear 605 is lost, the potential energy of the counterweight block 603 is converted into kinetic energy until the counterweight block 603 hits the outside of the pipe beam at the bottom, and the anti-collision detection can be completed. By adjusting the inclination angle of the knocking rod 602, the purpose of changing the impact force of the counterweight block 603 can be achieved, thereby meeting different experimental needs.
