[0026] Please refer to Figure 1 , Figure 1The figure shows a three-dimensional structural schematic diagram of an energy generating device for a pendulum impact test, which is used to evaluate the impact resistance of a sheet. The energy generating device includes a pendulum mechanism 10, a winding mechanism 20, a release control unit 30, and a frame 40. The pendulum mechanism 10 and the winding mechanism 20 are arranged at intervals on the frame 40. The pendulum mechanism 10 includes a pendulum 11 and a connecting member 12. One end of the connecting member 12 is connected to the frame 40, and the other end is connected to the end of the pendulum 11. One end of the release control unit 30 is connected to the side surface of the pendulum 11, and the other end is connected to the winding mechanism 20. The winding mechanism 20 is used to lift the pendulum 11 to a preset impact station through the release control unit 30. The release control unit 30 is used to release the pendulum 11 when the pendulum 11 is at the impact station, so that the pendulum 11 impacts the sheet 90 to be detected.

[0027] As one of the implementation manners, in the illustrated structure, the frame 40 is a portal structure with a cross beam arranged on two columns of equal height. The sheet 90 to be tested is placed below the cross beam. The pendulum mechanism 10 and the winding mechanism 20 are arranged at intervals on the cross beam of the frame 40. Among them, the pendulum mechanism 10 is arranged on the frame 40 adjacent to the sheet 90 below it, and the winding mechanism 20 is arranged at the end of the frame 40 away from the sheet 90. The pendulum mechanism 10 includes a pendulum 11 and a connecting member 12 for connecting the frame 40 and the pendulum 11. One end of the release control unit 30 is connected to the side surface of the pendulum 11, and the other end is connected to the winding mechanism 20. In this way, under the drive of the winding mechanism 20, the release control unit 30 lifts the pendulum 11 in a direction away from the sheet 90. When the pendulum 11 is lifted to the impact station preset by the user, the release control unit 30 releases the locking of the pendulum 11. The released pendulum 11 converts gravitational potential energy into kinetic energy and hits the sheet 90 to be tested. It can be understood that the user can calculate the energy generated at the moment when the pendulum 11 impacts the surface of the sheet 90 according to physical formulas (such as the law of conservation of energy or the law of conservation of momentum). Therefore, by adaptively adjusting parameters such as the weight or shape of the pendulum 11, the height or position of the impact station, and the length and shape of the connecting member 12, the impact resistance of the sheet 90 under different test requirements can be evaluated, which has the advantages of convenient use, low cost, short single-round detection cycle, and high universality.

[0028] In one embodiment, the connecting member 12 can be, for example, any one of a chain-like structure, a belt-like structure, a rope-like structure, and a rod-like structure, which is not limited herein.

[0029] In one embodiment, the user can also remotely or proximally control the operation of releasing the pendulum 11 by holding a controller for wirelessly controlling the release control unit 30.

[0030] Optionally, the winding mechanism 20 includes a winding drive unit 21 and a chain 22, the winding drive unit 21 is arranged on the frame 40, one end of the chain 22 is connected to the winding drive unit 21, and the other end is connected to the release control unit 30. Specifically, in this embodiment, the winding mechanism 20 includes a chain 22 and a winding drive unit 21 capable of releasing or accommodating the chain 22. The winding drive unit 21 is arranged at the end of the frame 40 away from the plate 90, and the end of the chain 22 is connected to the release control unit 30. In this way, when the winding drive unit 21 accommodates the chain 22, the release control unit 30 will pull up the pendulum 11 connected thereto under the drive of the chain 22.

[0031] Please refer to Figure 2 , Figure 2 The schematic diagram of the partial three-dimensional structure of the energy generating device at an angle is shown. A pulling portion 112 is provided on the pendulum 11, and a releasing portion 31 is provided at the end of the release control unit 30. The releasing portion 31 is detachably connected to the pulling portion 112. Specifically, in this embodiment, a pulling portion 112 protruding from the side surface is provided on the pendulum 11, and a releasing portion 31 detachably connected to the pulling portion 112 is provided at the end of the release control unit 30. In actual implementation, the user can manually connect the releasing portion 31 with the pulling portion 112 when the pendulum mechanism 10 is in the initial state of natural drooping, and then only needs to remotely start the winding drive unit 21 to perform the operation of receiving the chain 22, so that the pendulum 11 can be pulled up to the preset impact position.

[0032] In one embodiment, the release portion 31 of the release control unit 30 can be, for example, a clamping claw structure that can be relatively separated and closed. A through hole is provided on the pulling portion 112 of the pendulum 11, and the release portion 31 is arranged in the through hole to achieve the connection between the release control unit 30 and the pendulum 11.

[0033] Optionally, the lifting portion 112 is disposed on the pendulum 11 away from the swing direction of the pendulum 11. Specifically, in this embodiment, the direction in which the pendulum 11 swings from the preset impact station toward the plate 90 is set as the swing direction of the pendulum 11, and the lifting portion 112 is disposed on the side surface of the pendulum 11 away from the swing direction of the pendulum 11. In this way, when the pendulum mechanism 10 is in the initial state of natural droop, the efficiency of the user connecting the release portion 31 with the lifting portion 112 can be improved.

[0034] Optionally, a fixing loop 32 is provided at the end of the release control unit 30 away from the release part 31, and the chain 22 is detachably connected to the fixing loop 32. Specifically, in this embodiment, a circular fixing loop 32 is provided at the end of the release control unit 30 away from the release part 31, and the end of the chain 22 can pass through the fixing loop 32 to achieve the connection between the chain 22 and the release control unit 30. In the illustrated structure, the link at the end of the chain 22 has an opening, and this link passes through another complete link of the chain 22 and the fixing loop 32 to connect the chain 22 and the release control unit 30. In this way, both ends of the release control unit 30 can be detachably connected to the chain 22 and the pendulum 11 respectively, which improves the efficiency for the user to disassemble the release control unit 30 when it needs to be repaired or replaced.

[0035] Please refer to Figure 3 , Figure 3 which shows a partial three-dimensional structural schematic diagram of the energy generating device from another angle. The energy generating device further includes a fastener 50. The frame body 40 includes a base 41, and the base 41 and the connecting member 12 are hinged by the fastener 50. Specifically, in this embodiment, a base 41 protruding from the surface of the frame body 40 is provided on the end face of the frame body 40 opposite to the test plate 90, and the end of the base 41 and the connecting member 12 are hinged by the fastener 50. In this way, the connecting member 12 can swing reciprocally relative to the frame body 40 with the fastener 50 as the axis.

[0036] In one embodiment, the base 41 can be in a "U" shape. The end face of the base 41 is arranged on the frame body 40, and holes are provided on the two side walls of the base 41. The fastener 50 passes through these holes in sequence and the end of the connecting member 12 to realize the hinging between the base 41 and the connecting member 12.

[0037] Please refer to Figure 2 , the pendulum mechanism 10 further includes a swinging structure 13. One end of the swinging structure 13 is connected to the connecting member 12, and the other end is connected to the end of the pendulum 11. Specifically, in this embodiment, a swinging structure 13 is further provided between the connecting member 12 and the pendulum 11.

[0038] Please refer to Figure 4 , Figure 4A perspective structural schematic diagram of the swinging structure 13 is shown. The swinging structure 13 includes a first swinging member 131 and a second swinging member 132. The first swinging member 131 and the second swinging member 132 are hinged by a fastener 50. The connecting member 12 is connected to the end face of the first swinging member 131, and the end of the pendulum 11 is connected to the end face of the second swinging member 132. Specifically, in this embodiment, the swinging structure 13 is composed of the first swinging member 131 and the second swinging member 132, and the first swinging member 131 and the second swinging member 132 are rotatably connected by a fastener 50, that is, hinged. In actual implementation, the connecting member 12 connected to the end face of the first swinging member 131 can drive the first swinging member 131 to rotate relative to the fastener 50 during the swinging process, and the pendulum 11 connected to the end face of the second swinging member 132 can drive the second swinging member 132 to rotate relative to the fastener 50 under the inertia formed by its own weight.

[0039] Please refer to Figure 1 , Figure 3 and Figure 4 , the number of the connecting members 12 and the bases 41 is two. The two bases 41 are arranged on the frame body 40 at intervals perpendicular to the swinging direction of the pendulum 11. The two connecting members 12 are connected to the pendulum 11 through the swinging structure 13. Specifically, in this embodiment, the two bases 41 are perpendicular to the swinging direction of the pendulum 11 and are arranged at intervals on the end face of the frame body 40. One ends of the two connecting members 12 are respectively hinged to the two bases 41 by fasteners 50, and the other ends of the two connecting members 12 are connected to the pendulum 11 through the swinging structure 13. On the one hand, compared with only setting a single connecting member 12, setting two connecting members 12 can enable each connecting member 12 to share the gravity of the pendulum 11 received, reducing the probability of the connecting member 12 breaking. On the other hand, the two connecting members 12 can ensure that the swinging trajectory of the pendulum 11 when falling from the impact station will not deviate greatly, that is, restrict the running trajectory of the pendulum 11, effectively improving the detection accuracy and process safety.

[0040] Optionally, the first swinging member 131 and the second swinging member 132 are in a "U" shape. The number of the first swinging members 131 is two. The two first swinging members 131 are respectively hinged to the two side walls of the second swinging member 132 by fasteners 50. The two connecting members 12 are respectively connected to the end faces of the two first swinging members 131. Specifically, in this embodiment, as Figure 4 shown, the shapes of the first swinging member 131 and the second swinging member 132 are both in a "U" shape. The two first swinging members 131 are respectively arranged corresponding to the two side walls of the second swinging member 132 and are hinged by fasteners 50. Among them, the end faces of the two first swinging members 131 are respectively connected to the two connecting members 12, and the end face of the second swinging member 132 is connected to the end face of the pendulum 11.

[0041] In this application, a release control unit is provided on the winding mechanism. The pendulum is lifted to a preset impact station under the drive of the winding mechanism, and then the release control unit releases the pendulum so that it impacts the central area of the front surface of the plate to be detected, thereby completing the detection of the impact resistance performance of the plate. It is convenient to use, low in cost, short in single-round detection cycle, and has high universality.

[0042] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto.
