Moreover, after the luggage rack is damaged, the splash shield can be driven to tilt to pour out the damaged luggage rack fragments, thereby realizing self-cleaning of the luggage rack placement area, ensuring the smooth progress of subsequent tests, and also eliminating the process of manually cleaning the fragments. Moreover, before the splash shield rotates, the multiple splash shields can be driven to move radially at the same time and approach the axis of the fixed disk to push the broken rod. When the two ends of the horizontally placed rod are squeezed, they will become upright and lean against the inner wall of the splash shield until the splash shield gathers the multiple rods together. When the lever is lifted up, the rods fit tightly together. At this time, the splash plate can be used to tip the rods, so that the positions of the fallen rods are more uniform and more concentrated, which makes it easier to collect and reduces the labor intensity of the staff. Moreover, when the splash plate moves, the push rods one and the push rods two can be driven to extend from the placement groove to push the rods stuck between the splash plates, so that the rods are deflected and can be pushed normally by the splash plate. Moreover, the stuck rods can be accurately pushed by changing the angles of the push rods one and the push rods two. Moreover, the push rod one can also be driven to slide inside the push rod two, and the distance between the ends of the two push rods one can be adjusted to adapt to the changes in the positions of the splash plates. Even if the volume of the cavity formed by the multiple splash plates changes, the push rods one and the push rods two can still push in the cavity formed by the multiple splash plates to push the stuck rods in real time, which further ensures that the multiple rods are in a gathered state.

[0045] Specifically, a car luggage rack, also known as a roof luggage rack, is a rack installed on the roof of a car for placing and fixing luggage items. It is usually composed of two longitudinal rods and a number of crossbeams and is installed on the top of the car body. The crossbeams are usually equipped with snap-on fixing devices to facilitate the fixing of luggage. During the production process, the car luggage rack needs to be subjected to a durability test to simulate the vibration and impact that the vehicle may encounter during driving in order to test the stability and durability of the luggage rack and ensure that it can meet user needs and safety standards. When the existing vehicle luggage rack durability test device is used, the impact head 6 is used to impact the luggage rack multiple times. The durability of the luggage rack is obtained according to the number of impacts of the impact head 6 when the luggage rack is damaged. However, when the luggage rack is broken, the fragments of the luggage rack will splash around, which may easily injure the staff by mistake. Moreover, when the fragments are scattered around, it is not easy to clean up the fragments, resulting in the fragments remaining in the test area, affecting the normal progress of the subsequent durability test.

[0046] Therefore, in order to solve the above problems, when the present embodiment is in use, after the luggage rack is fixed, the luggage rack is in the cavity formed by the plurality of splash plates 8, and then the motor 4 is used to drive the winding roller 3 to rotate, so that the traction rope 5 is wound up, and the traction rope 5 slides on the support roller 30, so that the impact head 6 can be raised, and when the impact head 6 rises to a suitable height, the winding roller 3 releases the traction rope 5, so that the impact head 6 falls, so that the luggage rack is impacted, and then the impact head 6 rises, and the above operation is repeated, so that the luggage rack can be impacted multiple times, and then the durability of the luggage rack can be obtained according to the number of times the impact head 6 falls when the luggage rack is damaged;

[0047] When the luggage rack is damaged, the flying debris will be intercepted by the splash plate 8, and the debris will only be concentrated in the cavity formed by the multiple splash plates 8, thereby preventing the debris from flying around and accidentally injuring staff and damaging surrounding equipment;

[0048] When a luggage rack is damaged, since the luggage rack fragments remain in the cavity formed by the splash plate 8, it is inconvenient to test the subsequent luggage racks. Therefore, after the luggage rack is damaged, the motor 2 9 can be started to drive the rotating frame 10 to rotate, so that the splash plate 8 can be tilted, and the damaged luggage rack fragments can be poured out, thereby realizing self-cleaning of the luggage rack placement area, ensuring the smooth progress of subsequent tests, and also eliminating the process of manually cleaning the fragments;

[0049] Furthermore, since the luggage rack is composed of a plurality of rods, when the luggage rack debris is poured out, these rods may be in a mess, which is not conducive to the collection and processing of these rods by the staff. Therefore, before the splash plate 8 rotates, the motor 3 16 can be used to drive the connecting rod 1 28 and the gear 27 on one side to rotate, so that the gear ring 19 can be rotated to rotate the plurality of gears 27 at the same time. When the connecting rod 1 28 drives the connecting rod 2 29 to rotate, the sliding sleeve 14 can slide on the limiting rod 15, so that the plurality of splash plates 8 can move radially at the same time and approach the fixed The axis of the plate 13 is used to push the broken rod. At the same time, the spacing of the clamping blocks 21 is also adjusted to the minimum state. When the two ends of the horizontally placed rods are squeezed by the inner side of the splash plate 8, they will become upright and lean on the inner wall of the splash plate 8 until the splash plate 8 brings multiple rods together and the rods fit each other. At this time, the splash plate 8 is used to tip the rods, so that the orientation of the sliding rods can be more uniform and more concentrated, which is more convenient for collection, reducing the labor intensity of the staff, and because the rods are Under the extrusion of the splash plate 8, it becomes an upright state. Therefore, when multiple splash plates 8 move radially, the two ends of the rod may abut against the splash plate 8, causing the splash plate 8 to be stuck and unable to move. Therefore, when the splash plate 8 moves, the electric push rod 11 can be used to drive the lifting plate 18 to rise, so that the push rod 1 23 and the push rod 24 extend from the placement groove 22 to push the stuck rod, so that the rod is deflected, so that the rod can be normally pushed by the splash plate 8, and the push rod 1 23 can be changed by the motor 5 17. and the angle of the push rod 24 to accurately push the stuck rod, and the motor 4 25 can be used to drive the threaded rods 26 on both sides to rotate, so that the push rod 1 23 slides in the inner cavity of the push rod 24, and the distance between the ends of the two push rods 1 23 is adjusted to adapt to the change of the position of the splash plate 8. Even if the volume of the cavity formed by the multiple splash plates 8 changes, the push rods 1 23 and the push rods 24 can always push in the cavity formed by the multiple splash plates 8 to push the stuck rod in real time, further ensuring that the multiple rods are in a gathered state;

[0050] Therefore, by utilizing the gathering and discharging shield mechanism, when the luggage rack is damaged by the impact head 6, the splashing fragments will be intercepted by the splash plate 8, and the fragments will only be concentrated in the cavity formed by the multiple splash plate 8, thereby avoiding the fragments from splashing to the surrounding area, accidentally injuring staff and damaging surrounding equipment, and having high safety. Moreover, after the luggage rack is damaged, the splash plate 8 can be driven to tilt to pour out the damaged luggage rack fragments, thereby realizing self-cleaning of the luggage rack placement area, ensuring the smooth progress of subsequent tests, and also eliminating the process of manual cleaning of fragments. Moreover, before the splash plate 8 rotates, the multiple splash plate 8 can be driven to move radially at the same time and approach the axis of the fixed disk 13 to push the broken rod. When the two ends of the horizontally placed rod are squeezed, they will become upright and lean against the inner wall of the splash plate 8 until the splash plate 8 gathers the multiple rods together and the rods are tightly fitted. At this time, the splash plate 8 can be used to When the plate 8 tilts the rod, the position of the fallen rods can be more uniform and more concentrated, which makes it easier to collect and reduces the labor intensity of the staff. Moreover, when the splash plate 8 moves, the push rod 1 23 and the push rod 24 can be driven to extend from the placement groove 22 to push the rod stuck between the splash plate 8, so that the rod is deflected so that the rod can be pushed normally by the splash plate 8. Moreover, the angle of the push rod 1 23 and the push rod 24 can be changed to accurately push the stuck rod. Moreover, the push rod 1 23 can be driven to slide inside the push rod 24, and the distance between the ends of the two push rods 1 23 can be adjusted to adapt to the change of the position of the splash plate 8. Even if the volume of the cavity formed by the multiple splash plates 8 changes, the push rod 1 23 and the push rod 24 can always push in the cavity formed by the multiple splash plates 8 to push the stuck rod in real time, further ensuring that the multiple rods are in a gathered state.

[0051] Working principle: Place the car luggage rack to be subjected to the durability test between the two clamping blocks 21, and then start the electric push rods 20 on both sides at the same time, so that the two clamping blocks 21 can be moved simultaneously and approached to each other to clamp the car luggage rack, thereby ensuring the stability of the car luggage rack during the durability test. When the luggage rack is fixed, the luggage rack is in the cavity formed by multiple splash plates 8, and then the motor 4 is used to drive the winding roller 3 to rotate, so that the traction rope 5 is wound up, and the traction rope 5 slides on the support roller 30, so that the impact head 6 can rise. When the impact head 6 rises to a suitable height, the winding roller 3 releases the traction rope 5, so that the impact head 6 falls, so that the luggage rack is impacted, and then the impact head 6 rises. Repeat the above operation to subject the luggage rack to multiple impacts. Impact, and then the durability of the luggage rack is obtained according to the number of falls of the impact head 6 when the luggage rack is damaged; when the luggage rack is damaged, the splashing fragments will be intercepted by the splash plate 8, and the fragments will only be concentrated in the cavity formed by multiple splash plates 8, thereby avoiding the fragments from splashing to the surrounding area, accidentally injuring staff and damaging surrounding equipment; when a luggage rack is damaged, since the luggage rack fragments stay in the cavity formed by the splash plate 8, it is inconvenient to test the subsequent luggage racks, so after the luggage rack is damaged, the motor 2 9 can be started to drive the rotating frame 10 to rotate, so that the splash plate 8 can be tilted, and the damaged luggage rack fragments can be poured out, thereby realizing the self-cleaning of the luggage rack placement area, ensuring the smooth progress of subsequent tests, and also saving the process of manual cleaning of fragments;Furthermore, since the luggage rack is composed of a plurality of rods, when the luggage rack debris is poured out, these rods may be in a mess, which is not conducive to the collection and processing of these rods by the staff. Therefore, before the splash plate 8 rotates, the motor 3 16 can be used to drive the connecting rod 1 28 and the gear 27 on one side to rotate, so that the gear ring 19 can be rotated to rotate the plurality of gears 27 at the same time. When the connecting rod 1 28 drives the connecting rod 2 29 to rotate, the sliding sleeve 14 can slide on the limiting rod 15, so that the plurality of splash plates 8 can move radially at the same time and approach the fixed The axis of the plate 13 is used to push the broken rod. At the same time, the spacing of the clamping blocks 21 is also adjusted to the minimum state. When the two ends of the horizontally placed rods are squeezed by the inner side of the splash plate 8, they will become upright and lean on the inner wall of the splash plate 8 until the splash plate 8 brings multiple rods together and the rods fit each other. At this time, the splash plate 8 is used to tip the rods, so that the orientation of the sliding rods can be more uniform and more concentrated, which is more convenient for collection, reducing the labor intensity of the staff, and because the rods are Under the extrusion of the splash plate 8, it becomes an upright state. Therefore, when multiple splash plates 8 move radially, the two ends of the rod may abut against the splash plate 8, causing the splash plate 8 to be stuck and unable to move. Therefore, when the splash plate 8 moves, the electric push rod 11 can be used to drive the lifting plate 18 to rise, so that the push rod 1 23 and the push rod 24 extend from the placement groove 22 to push the stuck rod, so that the rod is deflected, so that the rod can be normally pushed by the splash plate 8, and the push rod 1 23 can be changed by the motor 5 17. and the angle of the push rod 24 to accurately push the stuck rod, and the motor 4 25 can be used to drive the threaded rods 26 on both sides to rotate, so that the push rod 1 23 slides in the inner cavity of the push rod 24, and the distance between the ends of the two push rods 1 23 is adjusted to adapt to the change of the position of the splash plate 8. Even if the volume of the cavity formed by the multiple splash plates 8 changes, the push rods 1 23 and the push rods 24 can always push in the cavity formed by the multiple splash plates 8 to push the stuck rod in real time, further ensuring that the multiple rods are in a gathered state;Therefore, by utilizing the gathering and discharging shield mechanism, when the luggage rack is damaged by the impact head 6, the splashing fragments will be intercepted by the splash plate 8, and the fragments will only be concentrated in the cavity formed by the multiple splash plate 8, thereby avoiding the fragments from splashing to the surrounding area, accidentally injuring staff and damaging surrounding equipment, and having high safety. Moreover, after the luggage rack is damaged, the splash plate 8 can be driven to tilt to pour out the damaged luggage rack fragments, thereby realizing self-cleaning of the luggage rack placement area, ensuring the smooth progress of subsequent tests, and also eliminating the process of manual cleaning of fragments. Moreover, before the splash plate 8 rotates, the multiple splash plate 8 can be driven to move radially at the same time and approach the axis of the fixed disk 13 to push the broken rod. When the two ends of the horizontally placed rod are squeezed, they will become upright and lean against the inner wall of the splash plate 8 until the splash plate 8 gathers the multiple rods together and the rods are tightly fitted. At this time, the splash plate 8 can be used to The plate 8 tilts the rods, so that the positions of the rods that have fallen are more uniform and more concentrated, which makes it easier to collect them, reducing the labor intensity of the staff. Moreover, when the splash plate 8 moves, the push rod 1 23 and the push rod 2 24 can be driven to extend from the placement groove 22 to push the rods stuck between the splash plates 8, so that the rods are deflected, so that the rods can be pushed normally by the splash plate 8. Moreover, the angles of the push rod 1 23 and the push rod 2 24 can be changed to accurately push the stuck rods. Moreover, the push rod 1 23 can also be driven to slide inside the push rod 2 24, and the distance between the ends of the two push rods 1 23 can be adjusted to adapt to the changes in the position of the splash plate 8. Even if the volume of the cavity formed by the multiple splash plates 8 changes, the push rod 1 23 and the push rod 2 24 can always push in the cavity formed by the multiple splash plates 8 to push the stuck rods in real time, further ensuring that the multiple rods are in a gathered state. ;
