Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0029] Example 1:

[0030] This utility model provides a side-tipping comprehensive test device: its structure includes an assembly frame 1, a gantry 2, a first recording device 3, a second recording device 4, an electrically controlled sling 5, a test pit 6, a side-tipping device 7, and a rope assembler 8. The side-tipping device 7 is provided on one side of the test pit 6, and the side-tipping device 7 flips towards the other side of the test pit 6. The gantry 2 is movably mounted on the top of the assembly frame 1. The first recording device 3 is mounted above the side-tipping device 7 via the gantry 2. The electrically controlled sling 5 is mounted above the test pit 6 via the gantry 2. The electrically controlled sling 5 is used for lifting vehicles in the test pit 6. The second recording device 4 is located in the same direction as the vehicle entering and exiting the side-tipping device 7. The first recording device 3 and the second recording device 4 are used for recording and supplementing light when the side-tipping device 7 flips the vehicle. Multiple rope assemblers 8 are evenly fixed on the top of the side-tipping device 7 away from the flipping direction. The rope assemblers 8 are used for assembling and fixing ropes.

[0031] The tilting device 7 includes a first electrically controlled telescopic rod 701, a main tilting plate 702, a weighing plate 703, a limiting plate 704, a gravity sensor 705, and a hinge seat 706. The hinge seat 706 is fixed inside the test pit 6. One side of the bottom of the main tilting plate 702 is hinged to the hinge seat 706. The bottom of the main tilting plate 702, away from the hinge seat 706, has a groove for assembling the first electrically controlled telescopic rod 701. The first electrically controlled telescopic rod 701 is hinged to the test pit 6 and the main tilting plate 702. The weighing plates 703 are used to drive the main flap 702 to flip along the hinge point with the hinge seat 706. The weighing plates 703 are arranged in groups of two, and the distance between each group of weighing plates 703 is less than or equal to the wheel distance. Multiple groups of weighing plates 703 are evenly embedded and installed on the top of the main flap 702 along the vehicle entry and exit direction. A gravity sensor 705 is installed between the bottom of the weighing plate 703 and the main flap 702. A limit plate 704 is installed on the top of the weighing plate 703. The limit plate 704 is used to restrict the vehicle from sliding towards the hinge seat 706.

[0032] The top of the weighing plate 703 is flush with the top of the main flip plate 702.

[0033] The first recording device 3 and the second recording device 4 are both composed of a high-speed camera and a fill light.

[0034] In use, the vehicle can be driven from one side of the rollover device 7 to the weighing plate 703 fixed on the rollover device 7 and parked. The first camera device 3 is moved to a suitable position by the gantry crane 2 to shoot and record the top view of the vehicle and provide supplementary lighting. At the same time, the second camera device 4, which is located in the same direction as the vehicle's entry and exit direction of the rollover device 7, will also shoot and record the front or rear side of the vehicle and provide supplementary lighting. This allows the device to more comprehensively record the vehicle's weight and data and shape changes during tilting or rollover, increasing the accuracy of the test and providing data reference.

[0035] During vehicle rollover testing, the vehicle can be fixed in position using the rope assembler 8, and the wheels can be limited by the limiting plate 704 on the main flip plate 702 to prevent the vehicle from sliding and rolling when tilted. Then, the first electrically controlled telescopic rod 701 is activated to support one side of the main flip plate 702, so that the main flip plate 702 can be flipped along the hinge of the hinge seat 706 to conduct the rollover test. During vehicle rollover testing, the ropes on the rope assembler 8 can be removed from fixing the vehicle, and the limiting plate 704 can be removed from limiting the wheels of the vehicle. Then, the first electrically controlled telescopic rod 701 is activated to flip the main flip plate 702 until the vehicle rolls into the test pit 6 to conduct the rollover test. After the vehicle rolls, it will enter the test pit 6, which can reduce the splashing of parts and facilitate subsequent inspection of the degree of damage. With the design of the gantry crane 2 and the electrically controlled sling 5 on the assembly frame 1, the vehicle can be easily lifted after the rollover test.

[0036] This enables the device to perform multiple functions, including weighing, tilting, and overturning tests, thus increasing its practicality.

[0037] Example 2:

[0038] Compared to Embodiment 1, the rope assembler 8 described in this embodiment includes a second electrically controlled telescopic rod 801, an assembly base 802, and a rope locking groove 803. The top of the assembly base 802 is provided with a recessed rope locking groove 803. The second electrically controlled telescopic rod 801 is embedded and fixed to one end of the assembly base 802. The telescopic rod body of the second electrically controlled telescopic rod 801 passes through the upper side of the rope locking groove 803 and connects to the other end of the assembly base 802.

[0039] The electrically controlled sling 5 consists of a winch, a locking hook, and a rope.

[0040] The assembly frame 1 is a combination of a support frame or a wall and a track beam.

[0041] The limiting plate 704 is telescopically mounted on the weighing plate 703, and when the limiting plate 704 is retracted, its top is flush with the weighing plate 703.

[0042] In use, the rope can be wrapped around or tied to the telescopic rod of the second electrically controlled telescopic rod 801 on the rope locking groove 803. During assembly, a loop knot or similar can be fixed and directly fitted onto the telescopic rod of the second electrically controlled telescopic rod 801. Then, the telescopic rod of the second electrically controlled telescopic rod 801 is controlled to close the rope locking groove 803, which is convenient and quick. When releasing the telescopic lock, the telescopic rod of the second electrically controlled telescopic rod 801 can be directly controlled to retract and disengage from the rope locking groove 803, so that the rope is released from the fixed connection. This achieves quick unlocking and locking of the rope, which is convenient and quick. Furthermore, the unlocking of the telescopic lock can be remotely controlled, which facilitates remote control of the vehicle to switch directly from a side tilt test to a rollover test, increasing the safety and practicality of the device. It avoids the dangers and inconveniences of the existing technology where rope fixing requires manual unlocking one by one. The rest of the structure and effect remain unchanged.

[0043] Example 3:

[0044] Compared to Embodiment 1, the limiting plate 704 in this embodiment includes a main body 70401, an elastic element 70402, a locking plate 70403, a locking groove 70404, and a handle groove 70405.

The locking grooves 70404 are arranged from top to bottom at the junction of the side end face of the weighing plate 703 and the main body 70401. The locking grooves 70404 are arc-shaped grooves. Two locking plates 70403 are provided and connected by the elastic element 70402. The two locking plates 70403 are penetrated and mounted on the main body 70401. The side of 0403 away from the elastic element 70402 is a convex arc shape that fits into the slot 70404. When using the device, the main body 70401 can be lifted directly to a suitable height through the handle slot 70405. When the main body 70401 is lifted, the locking plate 70403 of the main body 70401 is compressed and retracted into the main body 70401. At a suitable height, the locking plate 70403 of the main body 70401 will enter the matching slot 70404 for temporary fixation, realizing convenient lifting and use of the main body 70401. When the main body 70401 needs to be stored, it can be simply pressed down. It is convenient and quick, eliminating the inconvenience of assembling and fixing the limiting plate 704 with ropes, screws, etc. The rest of the structure and effect remain unchanged.

The power source 70406 is also embedded in the weighing plate 703 and protected by the power source cover 70407. The power source 70406 is used for powering and controlling the operation of the third electrically controlled telescopic rod 70408.

[0047] The first electrically controlled telescopic rod 701, the second electrically controlled telescopic rod 801, and the third electrically controlled telescopic rod 70408 are all hydraulic pumps, pneumatic pumps, or electric push rods.

[0048] Among them, the power source 70406 is an assembly that provides power and controls structures such as batteries and wireless controllers.

[0049] In use, the third electronically controlled telescopic rod 70408 can be remotely driven by the power source 70406 to drive the raising and lowering of the main board 70401, thereby realizing the remote control switching of the main board 70401 to limit and block the vehicle wheels. Combined with the rope assembler 8 structure of Embodiment 2, the vehicle tilt and rollover test switching can be realized remotely, avoiding the danger and inconvenience of manually approaching the test bench for switching.
