A sports equipment impact testing device and method

Abstract

This invention relates to the field of sports equipment manufacturing technology, and in particular to a sports equipment impact testing device and method. The testing device includes an impact component, a power component, and a control component. Utilizing the inherent elasticity of the sports equipment, when the equipment is impacted, it moves towards the first end of the sliding frame and quickly flies out, contacting the rebound plate. Normally functioning sports equipment, during its rebound, enters the receiving tube and eventually returns to the sliding frame, allowing the ping-pong ball to land again. This allows for direct testing of individual sports equipment under different impact forces, increasing the number of tests. If the sports equipment breaks or is damaged during increasingly intense impact testing, its elasticity will decrease significantly, and it will rebound directly into the equipment casing, thus confirming the sports equipment's maximum impact tolerance level. The entire process is automated, ensuring reasonable and effective impact testing of the sports equipment.

Description

Technical Field

[0001] This invention relates to the field of sports equipment manufacturing technology, and in particular to a sports equipment impact testing device and testing method. Background Technology

[0002] Sports equipment is a general term for all kinds of equipment, gear and supplies used in competitive sports and fitness exercises. Sports equipment includes fitness equipment, ball equipment, track and field equipment, water sports equipment, etc. Sports equipment and sports are interdependent and mutually reinforcing. The popularization of sports and the diversification of sports have led to the development of the types and specifications of sports equipment. Similarly, high-quality, stable, safe and reliable sports equipment can not only ensure that competitive sports are conducted in a fair and intense manner, but also create the necessary material conditions for promoting the improvement of sports level.

[0003] The development of impact testing for sports equipment is fundamentally driven by both safety and market innovation demands. The high intensity of competitive sports, the widespread adoption of sports, and the application of new materials (such as air cushions, gels, and carbon fibers) all place precise and quantitative demands on the dynamic mechanical properties of equipment. The core of impact testing for sports equipment remains the quantitative assessment of its cushioning performance, energy absorption, and structural integrity under dynamic loads.

[0004] For example, a common testing method for ball equipment is the squeeze-ejection test. However, for table tennis balls or similar ball equipment, due to the easily deformable nature of the table tennis ball shell, if the squeeze-ejection method is used to impact the ball, the shell may be dented due to the squeeze, resulting in inaccurate test data, which requires further improvement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a solution. To achieve the above objectives, the present invention provides a sports equipment impact testing device, comprising an impact component, a power component, and a control component; The impact assembly includes a device housing, a sliding frame, an impact spring, an impact plate, a rebound plate, and a receiving tube. The sliding frame is disposed inside the device housing, the impact spring is disposed inside the sliding frame, the impact plate is disposed inside the sliding frame and connected to the impact spring, the rebound plate is disposed corresponding to the first end of the sliding frame, and the rebound plate is used to rebound the sports equipment in the direction of the sliding frame after contact. The first end of the receiving tube is disposed corresponding to the rebound plate so that the sports equipment that rebounds normally falls into the receiving tube, and the second end of the receiving tube is connected to the first end of the sliding frame. The power assembly is connected to the impact plate, and the power assembly is used to drive the impact plate to move towards the second end of the sliding frame; The control component is used to control the power component to move the impact plate to the corresponding position of the sliding frame, so as to control the compression of the impact spring.

[0006] Furthermore, the first end of the storage tube is flared, and the inner surface of the first end of the storage tube is covered with shock-absorbing cloth to reduce excess elasticity of the sports equipment.

[0007] Furthermore, a material receiving sensor is also provided at the first end of the sliding frame, which is used to detect the material receiving status at the first end of the sliding frame.

[0008] Furthermore, the impact plate is equipped with a pressure sensor, which is used to acquire the impact force when in contact with sports equipment.

[0009] Furthermore, the power assembly includes a motor, a turntable connected to the output shaft of the motor, a connecting belt, a first connecting post, and a second connecting post. The first connecting post and the second connecting post are respectively connected to the impact plate and the sliding frame. The first end of the connecting belt is connected to the turntable, and the second end of the connecting belt passes around the first connecting post and is connected to the second connecting post. When the turntable rotates to different angle positions, the impact plate can be positioned at different positions on the sliding frame.

[0010] Furthermore, the control component is an electronic control component, which is used to control the rotation angle of the motor.

[0011] Furthermore, the control component includes a slide groove formed on the sliding frame and a sliding baffle slidably disposed in the slide groove. The first end and the second end of the sliding baffle both extend outside the slide groove. The first end of the sliding baffle is located on the side where the turntable is located. A limit plate is provided on the turntable. The limit plate is used to limit the angle of the turntable after contacting the sliding baffle. Multiple sets of sliding baffles and slide grooves are provided.

[0012] Furthermore, a roller is provided at the second end of the sliding baffle, and the sliding frame is provided with a first slide rail and a second slide rail. A pressing rod is slidably connected to the first slide rail. The pressing rod is provided with a pressing surface corresponding to the roller. A toothed rod is connected to the pressing rod. A sliding rod is slidably connected to the second slide rail. A return spring is connected to the sliding rod. A first material-pushing block and a stop block are provided on the sliding rod. The first material-pushing block is rotatably connected to the sliding rod and is provided with a torsion spring. The first material-pushing block corresponds to the toothed rod. The stop block is used to block the first material-pushing block. When the sliding rod moves to the first end of the sliding frame, it can push the toothed rod and the pressing rod to move synchronously. When the sliding rod moves to the second end of the sliding frame, the first material-pushing block rotates out of the toothed rod and cannot be pushed. A second material-pushing block is connected to the sliding rod. When the impact plate moves to the first end of the sliding frame, it can contact the second material-pushing block and move synchronously.

[0013] Furthermore, the sliding frame is also provided with a stop block, which is used to limit the maximum distance that the impact plate and the sliding rod can move toward the first end of the sliding frame.

[0014] The present invention also provides a method for impact testing of sports equipment, using a sports equipment impact testing device as described above, comprising: The sports equipment to be tested is placed inside the storage tube, and the sports equipment enters the first end of the sliding frame along the storage tube and moves towards the second end; The motor starts to rotate the turntable, the rotation of the turntable tightens and pulls the connecting belt, causing the first connecting post to drive the impact plate to move towards the second end of the sliding frame. The impact spring is compressed and accumulates elastic potential energy. The first connecting post contacts and limits the sliding baffle, controls the motor to rotate in the opposite direction, and the impact spring releases elastic potential energy, causing the impact plate to move quickly towards the first end of the sliding frame and generate an impact on the sports equipment. The sports equipment moves toward the first end of the sliding frame and flies out quickly, contacts the rebound plate and rebounds. During the rebound process, normal sports equipment enters the first end of the storage tube and falls along the storage tube into the first end of the sliding frame, thus completing the cyclic impact test process. The motor rotates at a greater angle to increase the compression of the impact spring. Different impact forces are tested on the same sports equipment. If the sports equipment breaks or is damaged during the test with continuously increasing impact forces, the elasticity will drop significantly. After contacting the rebound plate, the insufficient elasticity will cause it to fall into the equipment shell, thereby confirming the ultimate impact level that the sports equipment can withstand.

[0015] The above-described solution of the present invention has the following beneficial effects: The sports equipment impact testing device and method provided by this invention utilize the elasticity of the sports equipment itself. When the sports equipment is impacted, it moves towards the first end of the sliding frame and flies out quickly, contacting the rebound plate. After the impact, the normal sports equipment will enter the receiving tube during the rebound process and eventually return to the sliding frame, realizing the repositioning of the ping-pong ball. This allows for direct testing of individual sports equipment with different impact forces, increasing the number of tests. If the sports equipment breaks or is damaged during the test with continuously increasing impact forces, its elasticity will drop significantly. After contacting the rebound plate, it will not be able to rebound to the receiving tube due to insufficient elasticity, and will fall directly into the equipment shell. Under the action of gravity, it will be discharged from the outlet, thus confirming the ultimate impact level that the sports equipment can withstand. The entire process is carried out automatically without human intervention. The sports equipment impact testing device provided by this invention, through the setting of power components and control components, can conveniently and accurately control the position of the impact plate on the sliding frame, thereby controlling the impact force of each impact and achieving the purpose of gradually increasing the impact force on the sports equipment. The whole process is also automated, using electronic or mechanical control methods to ensure reasonable and effective impact testing of sports equipment. Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0018] To make the technical problems, solutions, and advantages of this invention clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0019] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1As shown, an embodiment of the present invention provides a sports equipment impact testing device, including an impact component 100, a power component 200, and a control component 300. The impact component 100 generates impact actions, subjecting the sports equipment to multiple impacts. The power component 200 drives the impact actions of the impact component 100, and the control component controls the impact force of the impact component 100. For example, during impact testing, the impact force needs to be increased progressively to test the impact resistance level of the sports equipment.

[0022] At the same time, such as Figure 2 , Figure 3 As shown, the impact assembly includes a housing 101, a fixed bracket 102 connected to the housing 101, a sliding frame 103 connected to the fixed bracket 102, and a rebound plate 104 connected to the housing 101. The sliding frame 103 holds the sports equipment, which is positioned near its first end. An impact spring 105 is installed inside the sliding frame 103. The first end of the impact spring 105 has an impact plate 106 attached to it, and the second end of the impact spring 105 abuts against the second end of the sliding frame 103. When the impact spring 105 is released, it drives the impact plate 106 to impact the sports equipment, causing the equipment to fly out from the first end of the sliding frame 103. The rebound plate 104 is positioned directly opposite the first end of the sliding frame 103 and is inclined relative to the horizontal plane. When the sports equipment contacts the rebound plate 104, it rebounds towards the sliding frame 103.

[0023] Based on this, in this embodiment, a receiving tube 107 is further provided inside the equipment housing 101. The receiving tube 107 is arranged opposite to the rebound plate 104 so that after the sports equipment hits the rebound plate 104, it can fall into the receiving tube 107 from its first end. The first end of the receiving tube 107 is positioned higher than the first end of the sliding frame 103, and the second end of the receiving tube 107 is connected to the first end of the sliding frame 103, but its position is lower than the first end, allowing the sports equipment to fall back onto the sliding frame 103. Additionally, a discharge port 108 is provided at the bottom of the equipment housing 101. When the sports equipment cannot enter the first end of the receiving tube 107 from the flared opening, it will fall directly into the bottom of the equipment housing 101 and enter the discharge port 108.

[0024] In this embodiment, the sports equipment uses a ping-pong ball as an example. Due to the excellent elasticity of the ping-pong ball, when it is impacted by the impact plate 106, it moves towards the first end of the sliding frame 103 and flies out quickly. The ping-pong ball will then come into contact with the rebound plate 104. Restricted by the inclined rebound plate 104, the ping-pong ball will bounce back in the opposite direction. During the rebound, the ping-pong ball will enter the first end of the receiving tube 107 and fall into the receiving tube 107, thus achieving a repositioning of the ping-pong ball. Therefore, when a single ping-pong ball is placed on the sliding frame 103, the impact plate 106 can test the same ping-pong ball with different impact forces, increasing the number of tests. If the ping-pong ball breaks during the test with continuously increasing impact force, its elasticity will decrease significantly. After contacting the rebound plate 104, due to insufficient elasticity, it will not be able to bounce back to the receiving tube 107 and will fall into the equipment housing 101. Under the action of gravity, it will be discharged outward from the discharge port 105, thus confirming the ultimate impact level that the ping-pong ball can withstand. A pressure sensor can also be installed on the corresponding surface of the impact plate 106 to obtain the impact force when it contacts the ping-pong ball.

[0025] In a preferred embodiment, the first end of the receiving tube 107 is flared to allow the ping-pong ball to fall smoothly into the receiving tube 107 after rebounding. Simultaneously, to prevent the ping-pong ball from bouncing excessively again after contacting the first end wall of the receiving tube 107, a shock-absorbing cloth 109 or similar soft material is laid on one of the inner surfaces of the first end of the receiving tube 107. This reduces excess elasticity of the ping-pong ball, allowing it to fall smoothly from the first end of the receiving tube 107 into the second end and into the sliding frame 103. Furthermore, in this embodiment, a material receiving sensor 110 is also provided at the junction of the first end of the sliding frame 103 (i.e., the second end of the receiving tube 107) and the sliding frame 103. The material receiving sensor 110 detects whether a ping-pong ball has fallen into the sliding frame 103 for the next impact test. The incoming material sensor 110 can be set as an energized stop bar. The first end of the sliding frame 103 is also set slightly higher than the second end. When the ping-pong ball falls into the sliding frame 103, it will roll towards the second end under the action of gravity until it contacts the energized stop bar, forcing the energized stop bar to deform and output a signal to confirm the incoming material.

[0026] At the same time, such as Figure 4As shown, the power assembly 200 includes a motor 201, a turntable 202 connected to the output shaft of the motor 201, a connecting belt 203 wound around the turntable 202, and a first connecting post 204 and a second connecting post 205. The base of the motor 201 is connected to the equipment housing 101. The first connecting post 204 and the second connecting post 205 are respectively connected to the impact plate 106 and the sliding frame 103. The first end of the connecting belt 203 is connected to the turntable 202, and the second end of the connecting belt 203 passes around the first connecting post 204 and connects to the second connecting post 205. Therefore, when the turntable 202 rotates, since the second end of the connecting belt 203 is fixedly connected to the second connecting post 205, and the relative position of the second connecting post 205 with the center of the turntable 202, i.e., the output shaft of the motor 201, remains unchanged, the first connecting post 204 and the impact plate 106 move towards the second end of the sliding frame 103, compressing the impact spring 105 and accumulating elastic potential energy. Furthermore, the elastic potential energy stored in the impact spring 105 can be controlled. That is, when the turntable 202 rotates to different angles, the impact plate 106 and the first end of the impact spring 105 can be positioned at different locations on the sliding frame 103, resulting in different compressions of the impact spring 105. Therefore, when the impact spring 105 releases its elastic potential energy, the impact plate 106 can generate different impact forces on the ping-pong ball, achieving the purpose of impact testing of the ping-pong ball under different impact forces.

[0027] It is worth mentioning that, in order to ensure the impact effect, when the impact spring 105 is released, the motor 201 will drive the turntable 202 to rotate rapidly in the opposite direction, so that the connecting belt 203 will be relaxed quickly. This way, when the impact spring 105 extends and resets, it will not be hindered by the tension of the connecting belt 203. The impact plate 106 can reach a preset speed when it contacts the ping-pong ball, thereby generating a preset impact force on the ping-pong ball for impact testing under a specific impact force.

[0028] In this embodiment, the control component 300 can be an electronically controlled component, which directly controls the rotation angle of the turntable 202 to adjust the compression of different impact springs 105, i.e., the generated impact force. Meanwhile, as Figure 5As an optional implementation, the control component in this embodiment includes a slide groove formed on the sliding frame 103 and a sliding baffle 301 slidably disposed within the slide groove. Both the first and second ends of the sliding baffle 301 extend outside the slide groove. The first end of the sliding baffle 301 is located on the side where the turntable 202 is located, and a limit plate 302 is also provided on the turntable 202. When the first end of the sliding baffle 301 is outside the slide groove, the turntable 202 rotates until the limit plate 302 contacts the first end of the sliding baffle 301, after which the turntable 202 can no longer rotate. Therefore, when multiple sets of slide grooves and sliding baffles 301 are provided, the rotation angle of the turntable 202 can be controlled by different sliding baffles 301. That is, when the turntable 202 rotates to a specified angle position, it can no longer rotate due to the contact action between the limit plate 302 and the sliding baffle 301, thus achieving the purpose of controlling the compression of the impact spring 105, and is more accurate than the control of a conventional motor 201. When different impact force tests are required, the first end of the sliding baffle 301 at different positions can be pushed out of the slide groove in sequence so that the turntable 202 can be rotated to different angles before the impact spring 105 is released.

[0029] At the same time, such as Figure 6 As shown, as a further improvement, a roller 303 is provided at the second end of the sliding baffle 301 in this embodiment. Simultaneously, a first slide rail and a second slide rail are provided at corresponding positions on the sliding frame 103. A pressing rod 304 is slidably connected to the first slide rail, and a toothed rod 305 is connected to the pressing rod 304. A slide rod 306 is slidably connected to the second slide rail, and a return spring 307 is connected between the slide rod 306 and the second slide rail. The first end of the return spring 307 is connected to the second end of the slide rod 306, and the second end of the return spring 307 is connected to the second slide rail or the sliding frame 103. Furthermore, a first feeding block 308 and a stop block 309 are provided on the slide rod 306. The first feeding block 308 is rotatably connected to the slide rod 306 and is equipped with a torsion spring. The first feeding block 308 corresponds to the toothed rod 305. The stop block 309 is used to block the first feeding block 308, so that when the first feeding block 308 rotates in the corresponding direction, it can only rotate to a preset angle. For example, taking the extension direction of the sliding frame 103 (the extension direction of the first slide rail and the second slide rail) as the first direction, and the direction perpendicular to the first direction as the second direction, the stop block 309 is set along the second direction so that the first feeding block 308 can rotate to the first direction when rotating clockwise in the figure, and can only rotate to the second direction when rotating counterclockwise. Therefore, when the slide rod 306 moves along the first direction and toward the first end of the sliding frame 103, it can actuate the toothed rod 305 and the pressing rod 304 to move synchronously; when the slide rod 306 moves along the first direction and toward the second end of the sliding frame 103, the first feeding block 308 will rotate out of the toothed rod 305 and will not be able to actuate the toothed rod 305 and the pressing rod 304 to move synchronously.

[0030] The slide bar 306 has a second material-pulling block 310 at its first end, corresponding to the impact plate 106. When the impact plate 106 moves towards the first end of the sliding frame 103, the edge of the impact plate 106 can contact the second material-pulling block 310, causing the slide bar 306 to move towards the first end of the sliding frame 103. This causes the toothed rod 305 and the pressing rod 304 to move synchronously, and stretches the return spring 307. When the impact plate 106 moves towards the second end of the sliding frame 103, the return spring 307 releases its elastic potential energy, causing the slide bar 306 to move towards the second end of the sliding frame 103 and return to its original position. During this process, the toothed rod 305 and the pressing rod 304 cannot move in the opposite direction, and the toothed rod 305 and the pressing rod 304 can remain in their final positions from the previous impact test.

[0031] Correspondingly, in this embodiment, a pressing surface is provided at the second end of the pressing rod 304. The pressing surface is also inclined relative to the first direction. When the pressing surface contacts the roller 303 at the second end of the sliding baffle 301, it can generate an outward force on the roller 303, that is, drive the sliding baffle 301 to move towards the second end, so that the first end of the sliding baffle 301 enters the groove, and the rotation angle of the turntable 202 is no longer restricted. Among them, when the rollers 303 connected to multiple sliding baffles 301 are arranged sequentially along the first direction, when the pressing rod 304 moves to different positions along the first direction, the first ends of different sliding baffles 301 can enter the groove, so that the turntable 202 can rotate to different angle positions. Understandably, the impact force in the impact test increases gradually, and the grooves on the turntable 202 are also distributed in a ring relative to the center. In order to make the rollers 303 at the second end of the sliding baffle 301 linearly distributed along the first direction, the second end of the sliding baffle 301 is set to an L-shape, and the short side lengths are different to ensure that the rollers 303 are linearly distributed along the first direction.

[0032] It should be noted that in this embodiment, when the impact plate 106 moves towards the first end of the sliding frame 103, it can contact the second material-pushing block 310, driving the slide rod 306 to move towards the first end of the sliding frame 103, thereby causing the first material-pushing block 308 to push the extrusion rod 304 to move synchronously. After the extrusion rod 304 moves, the first end of the corresponding sliding baffle 301 has already retracted into the slide groove for the next impact test, and the power component 200 can drive the next impact test. In addition, in order to ensure that the distance of the extrusion rod 304 moves consistently each time, and to be able to sequentially push the corresponding sliding baffle 301, a stop block can also be set on the sliding frame 103. The stop block limits the maximum distance that the impact plate 106 and the slide rod 306 move towards the first end of the sliding frame 103, avoiding inconsistencies in the displacement of the extrusion rod 304 under different elastic potential energies, and also preventing the impact plate 106 from impacting the incoming material sensor 110, etc.

[0033] It should be noted that the control method of the sliding baffle 301 provided in this embodiment is only an optional implementation method. This method can, to a certain extent, orderly conduct impact tests with progressively increasing impact forces. Based on actual conditions, only the electronic control components can be used to control the motor 201, which results in a simpler structural setup. Both methods can be configured based on actual conditions.

[0034] Based on the same inventive concept, this embodiment also provides a method for impact testing of sports equipment. Using the sports equipment impact testing device described above, before use, the sports equipment to be tested, such as a ping-pong ball, is placed inside the receiving tube 107. The ping-pong ball enters the first end of the sliding frame 103 along the receiving tube 107 and rolls towards the second end until it contacts the incoming material sensor 110, obtaining an incoming material signal. At this time, the motor 201 starts, causing the turntable 202 to rotate. The rotating turntable 202 tightens and pulls the connecting belt 203, causing the first connecting post 204 to drive the impact plate 106 towards the second end of the sliding frame 103. During this process, the impact spring 105 compresses and accumulates elastic potential energy. After the first connecting post 204 contacts the sliding baffle 301, it is limited, and the motor 201 cannot continue to rotate. At this time, the motor 201 is controlled to rotate in the opposite direction, and the impact spring 105 releases its elastic potential energy, causing the impact plate 106 to move rapidly towards the first end of the sliding frame 103 and impact the ping-pong ball. The ping-pong ball moves towards the first end of the sliding frame 103 and flies out quickly. It contacts the rebound plate 104 and rebounds. During the rebound, the ping-pong ball enters the first end of the receiving tube 107, falls into the receiving tube 107, and then falls back into the first end of the sliding frame 103, repeating the impact test process. At this time, the motor 201 needs to rotate more to make the impact spring 105 generate more compression. Finally, different impact forces are tested on the same ping-pong ball. If the ping-pong ball breaks during the test of continuously increasing impact force, the elasticity of the ping-pong ball will drop significantly. After contacting the rebound plate, due to insufficient elasticity, it cannot rebound to the receiving tube and will fall into the equipment housing 101. Under the action of gravity, it will be discharged from the discharge port 108, thus confirming the ultimate impact level that the ping-pong ball can withstand.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.

10. A method for impact testing of sports equipment, using a sports equipment impact testing device as described in any one of claims 7-9, characterized in that, include: The sports equipment to be tested is placed inside the storage tube, and the sports equipment enters the first end of the sliding frame along the storage tube and moves towards the second end; The motor starts to rotate the turntable, the rotation of the turntable tightens and pulls the connecting belt, causing the first connecting post to drive the impact plate to move towards the second end of the sliding frame. The impact spring is compressed and accumulates elastic potential energy. The first connecting post contacts and limits the sliding baffle, controls the motor to rotate in the opposite direction, and the impact spring releases elastic potential energy, causing the impact plate to move quickly towards the first end of the sliding frame and generate an impact on the sports equipment. The sports equipment moves toward the first end of the sliding frame and flies out quickly, contacts the rebound plate and rebounds. During the rebound process, normal sports equipment enters the first end of the storage tube and falls along the storage tube into the first end of the sliding frame, thus completing the cyclic impact test process. The motor rotates at a greater angle to increase the compression of the impact spring. Different impact forces are tested on the same sports equipment. If the sports equipment breaks or is damaged during the test with continuously increasing impact forces, the elasticity will drop significantly. After contacting the rebound plate, the insufficient elasticity will cause it to fall into the equipment shell, thereby confirming the ultimate impact level that the sports equipment can withstand.
