Abstract
Description
Technical Field
[0001] This invention belongs to the field of sports equipment technology, and more specifically, relates to a whipping simulation racket. Background Technology
[0002] The core power generation technique in racket sports (such as high clears and smashes in tennis and badminton) lies in the "whipping effect," which involves the sequential acceleration and braking of large muscle groups to small muscle groups at the ends of the body to effectively transfer momentum to the racket head, reaching maximum speed and producing a clear impact sensation at the moment of impact. Traditional training methods, including air swings, weighted swings, and elastic resistance training, all have significant shortcomings. First, practice swinging without resistance and endpoint feedback makes it difficult for practitioners to perceive the timing and intensity of power release, easily leading to incorrect power generation rhythm. Second, while swinging weights, such as heavy rackets or weighted bats, can increase power, their inertial characteristics differ from those of a real shot. Moreover, the weights provide continuous resistance throughout the swing, rather than simulating the whipping process of "acceleration-sudden release," and lack key impact point feedback, making it impossible to train the precise coordination of "braking" and "power generation." Third, elastic resistance training, such as using resistance bands, has a unidirectional resistance that increases linearly with stretching, which does not match the complex three-dimensional swing trajectory and the sudden force at the moment of impact, and similarly fails to simulate the feeling of impact.
[0003] Furthermore, while some complex robots or large-scale simulation devices exist, none are suitable for personal, portable, and specialized training. Therefore, there is an urgent need for a training device with a simple structure, strong feedback, and the ability to accurately simulate the "acceleration-impact" sensation at the end of a whipping motion, to help users efficiently develop muscle memory and optimize their force application techniques. Summary of the Invention
[0004] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides a whipping simulation racket that can simulate the "whipping" feeling and impact feedback at the moment of hitting the ball. It is easy to carry and can be used not only for special power training in racket-swinging sports such as tennis and badminton, but also as a regular racket.
[0005] To achieve the above objectives, the present invention provides a racket, including a handle, a racket head, a telescopic guide mechanism, and an elastic element; the telescopic guide mechanism includes a first guide rod and a second guide rod, which are coaxially nested and can move axially relative to the first guide rod; the first guide rod is fixedly connected to the handle, and the second guide rod is fixedly connected to the racket head; the elastic element is disposed within the first guide rod or the second guide rod, with one end fixed relative to the first guide rod and the handle, and the other end fixed relative to the second guide rod; the elastic element is used to cause the second guide rod or the racket head to abut against the first guide rod when no external force is applied, and to pull the second guide rod towards the handle when the telescopic guide mechanism is extended to its maximum length, so that the second guide rod or the racket head abuts against the first guide rod again.

[0010] In some embodiments, the racket further includes a lock-release mechanism for locking or releasing the second guide rod.
[0011] In some embodiments, the locking-release mechanism includes a button, a connecting rod, a latch, a reset element, and a fulcrum; a second guide rod is disposed within a first guide rod and has a groove on its outer wall for accommodating the latch; one end of the connecting rod is connected to the button, and the other end is connected to the latch; the portion of the connecting rod between the button and the latch is hinged to the fulcrum, and the fulcrum is fixed relative to the handle and the first guide rod; one end of the reset element is fixed relative to the handle and the first guide rod, and the other end acts on the side opposite to the button with reference to the fulcrum.
[0012] In some implementations, the reset element is a spring; in the initial state, the reset element is in a pre-compressed state, pushing the locking pin inward toward the first guide rod, so that the pin head of the locking pin is embedded in the slot of the second guide rod, thereby achieving locking; when the user presses the button, the reset element is further compressed, and when the pin head of the locking pin is completely withdrawn from the slot of the second guide rod, the second guide rod is released, and the lock is released.
[0013] In some embodiments, the racket further includes a rigid limiting structure; the rigid limiting structure includes a rigid pin radially disposed on the inner wall of the first guide rod; the slot of the second guide rod has a guiding slope at the entrance near the handle side for guiding the locking pin to slide in and achieve locking; the slot of the second guide rod has a bearing surface near the racket head; in the initial state, the first guide rod and the second guide rod abut against the rigid pin through the bearing surface, and the pin head of the locking pin is embedded in the slot of the second guide rod to achieve locking; after the user swings the racket, when the second guide rod abuts against the first guide rod again, the bearing surface and the rigid pin collide, and the pin head is embedded in the slot of the second guide rod again to achieve locking.

[0016] In some embodiments, the frisbee includes a disc structure with a diameter of 15cm to 28cm, and the disc structure is made of polyethylene or polypropylene.
[0017] Overall, compared with existing technologies, the technical solutions conceived in this invention have the following beneficial effects: Simulating realistic end-impact feedback, the unique "energy storage-sudden release-impact" mechanism produces a sudden acceleration and clearly perceptible physical impact (sound and vibration) extremely similar to a real shot. This core feedback is completely impossible to provide with practice swinging or swinging heavy objects, greatly enhancing the realism and effectiveness of training; providing precise timing training for power generation, by allowing the user to actively select the timing to trigger the swing, forcing them to perceive and practice synchronizing maximum power generation with the release point, effectively training the coordination and timing of the power chain. It features enhanced mechanical feel; it strengthens the neuromuscular control of "braking-powering," simulating the process of the racket head suddenly accelerating and then stopping at the moment of impact.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0020] like Figure 1 As shown, the whipping simulation racket of this embodiment includes: a handle 1, a racket head 2, a telescopic guide mechanism, and an elastic element 3. The telescopic guide mechanism includes a first guide rod 31 and a second guide rod 32, which are coaxially nested and can move axially relative to the first guide rod 31. The first guide rod 31 is fixedly connected to the handle 1, and the second guide rod 32 is fixedly connected to the racket head 2. The elastic element 3 is disposed within the first guide rod 31 or the second guide rod 32, with one end fixed relative to the first guide rod 31 and the handle 1, and the other end fixed relative to the second guide rod 32.
[0021] Initially, the second guide rod 32 or the racket head 2, under the action of the elastic element 3, abuts against the first guide rod 31. When the user swings the racket, the racket head 2, under the action of centrifugal force, overcomes the initial force of the elastic element 3, driving the second guide rod 32 to move away from the handle 1. The telescopic guide mechanism extends, and the elastic element 3 further accumulates potential energy until the racket head 2 slides, causing the elastic element 3 to reach its maximum energy storage state. Figure 2 As shown. Then, the elastic element 3 releases the stored potential energy, violently pulling the second guide rod 32 towards the handle 1 to accelerate. The second guide rod 32 or the racket head 2 then comes into contact with the first guide rod 31 again, producing a strong sound, vibration and tactile feedback, simulating the instantaneous feeling of hitting the ball at the end of a "whip".
[0022] Through the above methods, on the one hand, the neuromuscular control of "braking-power generation" is strengthened. Specifically, it simulates the process of the racket head suddenly accelerating and then stopping at the moment of impact, which helps train the emergency braking ability of the distal small muscle groups after power generation. This is key to improving hitting power and control accuracy. On the other hand, it forms a unique "energy storage-sudden release-impact" mechanism. Specifically, it produces a sudden acceleration and a clearly perceptible physical impact (sound and vibration) that is extremely similar to a real hitting. This core feedback cannot be provided by swinging in the air or swinging heavy objects, greatly enhancing the realism and effectiveness of the training.
[0023] In some embodiments, the handle 1 is covered with an anti-slip material. In some embodiments, the second guide rod 32 is inside the first guide rod 31. In some embodiments, the racket head 2 is detachably connected to the second guide rod 32. In some embodiments, the elastic element 3 is detachably connected to the first guide rod 31 and the second guide rod 32. In some embodiments, the elastic element 3 is a spring or a tension band. In some embodiments, the racket head 2 is a metal counterweight, and the training intensity can be adjusted by changing racket heads of different weight classes and elastic elements with different elastic coefficients.
[0024] In some embodiments, the racket head 2 is a frisbee, which detaches from the second guide rod when the user's swing force reaches a certain limit. In some embodiments, the frisbee includes a disc structure with a diameter of 15cm to 28cm, and the disc structure is made of polyethylene (PE) or polypropylene (PP).
[0025] In some implementations, such as Figure 1 As shown, the spring or elastic band constituting the elastic element 3 is connected to a first guide rod 31 at one end near the handle 1 and to a second guide rod 32 at the other end near the racket head 2. Initially, the spring or elastic band constituting the elastic element 3 is in a pre-stretched state, and the second guide rod 32 abuts against the first guide rod 31 under the action of the elastic element 3. After the user swings the racket, the telescopic guide mechanism extends, further stretching the spring or elastic band constituting the elastic element 3.
[0026] The state changes of the spring or elastic band constituting the elastic element 3 when one end is connected to the handle 1 and the other end is connected to the second guide rod 32 are as follows: Figure 1 The structures shown are similar and will not be described in detail here.
[0027] In other implementations, such as Figure 3 As shown, the spring constituting the elastic element 3 has its end near the handle 1 connected to the second guide rod 32, and its end near the racket head 2 connected to the first guide rod 31. Initially, the spring constituting the elastic element 3 is in a pre-compressed state, and the second guide rod 32 abuts against the first guide rod 31 under the action of the elastic element 3. After the user swings the racket, the telescopic guide mechanism extends, further compressing the spring constituting the elastic element 3 until the racket head 2 slides, causing the elastic element 3 to reach its maximum energy storage state, as shown. Figure 4 As shown. Then, the elastic element 3 releases the stored potential energy, violently pulling the second guide rod 32 towards the handle 1 to accelerate. The second guide rod 32 and the first guide rod 31 come into contact again, producing a strong sound, vibration and tactile feedback, simulating the instantaneous feeling of "whipping" the end of the ball.
[0028] In some embodiments, multiple springs constituting the elastic element 3 are evenly arranged between the first guide rod 31 and the second guide rod 32, so that the second guide rod 32 can move stably in the axial direction relative to the first guide rod 31.
[0029] In addition, the second guide rod can also be set outside the first guide rod, only requiring adjustment. Figures 1 to 4 The structure shown can be easily modified, and will not be described in detail here.
[0030] Furthermore, the whipping simulation racket of this embodiment of the invention also includes a locking-release mechanism for locking the second guide rod (preventing the second guide rod from moving axially relative to the first guide rod) or releasing it (allowing the second guide rod to move axially relative to the first guide rod under external force) to provide precise power timing training. By having the user actively select the timing to trigger the swing, the user is forced to perceive and practice synchronizing the maximum power with the release point, effectively training the coordination and timing of the power chain.
[0031] In the initial state, the lock-release mechanism locks the second guide rod, which the user can release during a swing. When the racket head 2 is a disc, if the user locks the second guide rod during a swing, the disc will detach from the second guide rod and fly out when the swing force reaches the first limit. If the user releases the second guide rod during a swing, the length of the telescopic guide mechanism will change during this process, and the disc will detach from the second guide rod and fly out when the swing force reaches the second limit.
[0032] In some implementations, the locking-release mechanism is an electronic latch, controlled by a button located on the handle.
[0033] In addition, such as Figure 5 As shown, the locking-release mechanism of this embodiment can also be a mechanical latch, specifically including a button 4, a connecting rod 5, a locking pin 6, a reset element 7, and a fulcrum 8. Correspondingly, the outer wall of the second guide rod 32 is provided with a groove for accommodating the locking pin 6. Specifically, the button 4 is embedded in the side wall of the handle 1, and its axis is perpendicular to the axis of the handle 1. One end of the connecting rod 5 is connected to the button 4, and the other end is connected to the locking pin 6. The portion of the connecting rod 5 between the positions where it connects to the button 4 and the locking pin 6 is hinged to the fulcrum 8, and the fulcrum 8 is fixed relative to the handle 1 and the first guide rod 31. One end of the reset element 7 is fixed relative to the handle 1 and the first guide rod 31, and the other end is fixed to the locking pin 6.
[0034] The following describes in detail the usage process of the racket with mechanical buckle in this embodiment of the invention, taking the case where the racket head does not detach from the second guide rod as an example.
[0035] In the initial state, the second guide rod 32 or the racket head 2, under the action of the elastic element 3, abuts against the first guide rod 31, such as... Figure 5 As shown, the reset element 7 pushes the locking pin 6 inward toward the first guide rod 31, so that the pin head of the locking pin 6 is embedded in the slot of the second guide rod 32, thereby achieving locking.
[0036] The user begins the swing motion. When the swing reaches the preset acceleration point, pressing button 4 causes link 5 to rotate around fulcrum 8, pulling pin 6 to move outwards towards the first guide rod 31. Reset element 7 further accumulates potential energy. When the pin head of pin 6 completely exits the slot, the second guide rod 32 is released, and the lock is disengaged. Figure 6 As shown. After the lock is released, under the action of centrifugal force, the racket head 2 overcomes the initial force of the elastic element 3 and drives the second guide rod 32 to move away from the handle 1. The telescopic guide mechanism extends, and the elastic element 3 further accumulates potential energy until the racket head 2 slides and the elastic element 3 reaches the maximum energy storage state. Then, the elastic element 3 releases the accumulated potential energy and violently pulls the second guide rod 32 to accelerate towards the handle 1. The second guide rod 32 or the racket head 2 comes into contact with the first guide rod 31 again, producing a strong sound, vibration and tactile feedback, simulating the instantaneous feeling of hitting the ball at the end of a "whip".
[0037] After the "whipping" action ends and the user releases button 4, the reset element 7 releases its stored potential energy, pushing the locking pin 6 to move inward toward the first guide rod 31. If the second guide rod 32 has already returned to its precise position, the pin head of the locking pin 6 will directly align with the slot, snapping into place with a "click," and button 4 will reset. Figure 5 As shown. If the second guide rod 32 has not fully returned to its original position at this time, the locking pin 6 will press against the outer wall of the second guide rod 32. As the second guide rod 32 continues to return to its original position, once the slot slides past the pin head, the locking pin 6 will immediately spring in and lock, and the button 4 will reset. Figure 5 As shown. At this point, the racket returns to its initial locked state, awaiting the next trigger.
[0038] In some embodiments, the fulcrum 8 is fixed to the handle 1. In other embodiments, the fulcrum 8 is fixed to the first guide rod 31. In some embodiments, one end of the connecting rod 5 is hinged to the button 4. In some embodiments, the other end of the connecting rod 5 is hinged to the locking pin 6. In some embodiments, one end of the reset element 7 is fixed to the handle 1. In other embodiments, one end of the reset element 7 is fixed to the first guide rod 31. In other embodiments, the other end of the reset element 7 is fixed to the portion of the connecting rod 5 between the fulcrum 8 and the locking pin 6 (in fact, with reference to the fulcrum 8, the other end of the reset element 7 only needs to be fixed to the side of the connecting rod 5 opposite to the button 4). In some embodiments, the groove on the outer wall of the second guide rod 32 has a guide ramp at the entrance near the handle 1, for guiding the locking pin 6 into the groove to achieve locking when the user releases the button 4 and the second guide rod 32 has not fully returned to its original position.
[0039] In some embodiments, the reset element 7 is a spring. Initially, the spring constituting the reset element 7 is in a pre-compressed state. When the user presses button 4, the spring constituting the reset element 7 is further compressed. In some embodiments, the racket head 2 is a tennis racket head or a badminton racket head. By replacing the racket head with a tennis racket head or a badminton racket head suitable for normal use, the switch from a training racket to a regular racket is achieved without triggering button 4.
[0040] Furthermore, the whipping simulation racket of this embodiment of the invention also includes a rigid limiting structure, which is used to create a sudden and violent braking when the second guide rod 32 or the racket head 2 comes into contact with the first guide rod 31 again after the user swings the racket, forming a violent impact and enhancing the instantaneous feeling of hitting the ball at the end of the "whip".
[0041] Specifically, such as Figure 1 As shown, the rigid limiting structure 39 is disposed on the outer wall of the second guide rod 32 and has an annular end face 40. In the initial state, the first guide rod 31 and the second guide rod 32 abut against the rigid limiting structure 39 through the end of the first guide rod 31 near the racket head 2; after the user swings the racket, when the second guide rod 32 abuts against the first guide rod 31 again, the end of the first guide rod 31 near the racket head 2 and the rigid limiting structure 39 will have a violent impact, enhancing the "whipping sensation".
[0042] like Figure 3As shown, the rigid limiting structure 39 is disposed on the outer wall of the second guide rod 32 and has an annular end face 40. The inner wall of the first guide rod 31 is provided with a first mounting part 45, and the outer wall of the second guide rod 32 is also provided with a second mounting part 46. One end of the spring constituting the elastic element 3 is connected to the first mounting part 45, and the other end is connected to the second mounting part 46. In the initial state, the second guide rod 32 and the first guide rod 31 abut against the rigid limiting structure 39 through the first mounting part 45. The first mounting part 45 simultaneously undertakes two key functions: mounting the elastic element and bearing the impact. That is, in addition to connecting the spring constituting the elastic element 3, the first mounting part 45 is also used to generate a violent impact with the rigid limiting structure 39 when the second guide rod 32 and the first guide rod 31 abut against each other again after the user swings the racket, thus enhancing the "whipping sensation".
[0043] In some embodiments, the rigid limiting structure 39 is made of metal. The rigid limiting structure 39 is integrally formed with the second guide rod 32 or is embedded separately.
[0044] Furthermore, regardless of the installation method of the elastic element 3, such as Figure 7 As shown, a rigid limiting structure according to an embodiment of the present invention includes a first limiting structure 41 and a second limiting structure 42. The first limiting structure 41 is disposed on the inner wall of the first guide rod 31, and the second limiting structure 42 is disposed on the outer wall of the second guide rod 32. In the initial state, the first guide rod 31 and the second guide rod 32 abut against each other through the first limiting structure 41 and the second limiting structure 42; when the user swings the racket, the second guide rod 32 abuts against the first guide rod 31 again, and the first limiting structure 41 and the second limiting structure 42 generate a violent impact, enhancing the "whipping sensation".
[0045] In some embodiments, the first limiting structure 41 has an annular end face disposed on the inner wall of the first guide rod 31, and the second limiting structure 42 has an annular end face disposed on the outer wall of the second guide rod 32. In some embodiments, the first limiting structure 41 and the second limiting structure 42 are made of metal. The first limiting structure 41 is integrally formed with the first guide rod 31 or is separately embedded; similarly, the second limiting structure 42 is integrally formed with the second guide rod 32 or is separately embedded. In some embodiments, such as Figure 7 As shown, when the first guide rod 31 and the second guide rod 32 abut, the second limiting structure 42 is inside the first guide rod 31. In other embodiments, when the first guide rod 31 and the second guide rod 32 abut, the second limiting structure 42 is outside the first guide rod 31.
[0046] Furthermore, such as Figure 8As shown, another embodiment of the rigid limiting structure of the present invention includes a rigid pin 51 radially disposed on the inner wall of the first guide rod 31. Correspondingly, the slot 44 of the second guide rod 32 has a guide slope 52 at the entrance near the handle 1, for guiding the locking pin 6 to slide into the slot 44 to achieve locking. The slot 44 of the second guide rod 32 has a bearing surface 53 on the side near the racket head. The bearing surface 53 is a plane perpendicular or nearly perpendicular to the axis of the second guide rod 32, for generating a violent impact with the rigid pin 51 to enhance the "whipping sensation".
[0047] At this time, the slot 44 of the second guide rod 32 is a precision-designed multi-functional mechanical interface that simultaneously undertakes three key functions: locking, bearing impact, and automatic guidance. Taking the case where the racket head does not detach from the second guide rod as an example, the specific description is as follows.
[0048] In the initial state, the first guide rod 31 and the second guide rod 32 abut against each other through the bearing surface 53 and the rigid pin 51. The reset element 7 pushes the locking pin 6 inward toward the first guide rod 31, so that the pin head of the locking pin 6 is embedded in the slot 44 of the second guide rod 32, thereby achieving locking.
[0049] The user begins the swing motion. When the swing reaches the preset acceleration point, pressing button 4 causes link 5 to rotate around fulcrum 8, pulling pin 6 to move outwards towards the first guide rod 31. Reset element 7 further accumulates potential energy. When the pin of pin 6 completely exits from slot 44, the second guide rod 32 is released, and the lock is released. Under the action of centrifugal force, racket head 2 overcomes the initial force of elastic element 3, driving the second guide rod 32 to move away from handle 1. The telescopic guide mechanism extends, and elastic element 3 further accumulates potential energy until racket head 2 slides, causing elastic element 3 to reach its maximum energy storage state. Then, elastic element 3 releases the accumulated potential energy, violently pulling the second guide rod 32 towards handle 1 for accelerated movement. The second guide rod 32 and the first guide rod 31 come into contact again, and the bearing surface 53 violently impacts the rigid shaft pin 51, enhancing the instantaneous feeling of "whipping" the ball at the end.
[0050] After the "whipping" action ends and the user releases button 4, the reset element 7 releases its stored potential energy, pushing the locking pin 6 towards the inside of the first guide rod 31. If the second guide rod 32 has already returned to its precise position, the pin head of the locking pin 6 will directly align with the locking slot 44, snapping into place with a "click." If the second guide rod 32 has not yet fully returned to its position, the locking pin 6 will press against the outer wall of the second guide rod 32. As the second guide rod 32 continues to return to its position, the locking pin 6, under the action of the guide slope, will snap into the locking slot 44 and lock. At this point, the racket returns to its initial locked state, awaiting the next trigger.
[0051] In some embodiments, the outer diameter of the portion of the second guide rod 32 between the slot 44 and the handle 1 is smaller than the outer diameter of the portion between the slot 44 and the racket head 2. This ensures that when the second guide rod 32 moves axially relative to the first guide rod 31 after the lock is released, the rigid pin 51 does not contact the outer wall of the first guide rod 31, thus not hindering the movement of the first guide rod 31. Furthermore, this allows the bearing surface 53 and the rigid pin 51 to collide violently when the second guide rod 32 and the first guide rod 31 come into contact again after the swing, enhancing the "whipping sensation".
[0052] This invention simulates realistic end-of-strike impact feedback. Its unique "energy storage-release-impact" mechanism produces a sudden acceleration and clearly perceptible physical impact (sound and vibration) remarkably similar to a real shot. This core feedback is completely unavailable in practice swings or swinging heavy objects, greatly enhancing the realism and effectiveness of training. It provides precise timing training for power generation, allowing users to actively choose the timing during the swing, forcing them to synchronize maximum power generation with the release point, effectively training the coordination and timing of the power chain. It strengthens neuromuscular control of "braking-power generation," simulating the sudden acceleration and subsequent stop of the racket head at the moment of impact, helping to train the emergency braking ability of the distal small muscle groups after power generation—key to improving hitting power and control precision. It is safe, portable, and highly customizable; during power generation training, no ball is hit, allowing safe use in any open space. The replaceable racket head and elastic elements allow users to adjust training intensity according to their strength level and training stage, and switch the racket from training mode back to normal use. Its simple and reliable, purely mechanical structure is low-cost, durable, and suitable for mass production and widespread adoption.
