Description

Technical Field

[0001] This invention relates to the field of golf technology, and in particular to a golf swing training method. Background Technology

[0002] The core challenges of a golf swing lie in controlling the clubface angle, maintaining swing path stability, and efficiently transferring body energy to the clubhead. These three factors directly determine the direction, stability, and distance of the shot. Current golf training methods and related equipment generally suffer from the following technical deficiencies: First, traditional training relies too much on imitating movement patterns, wrist rolling, and controlling the timing of the shot. Trainees find it difficult to establish a stable body force structure, which can easily lead to problems such as active hand force generation and excessive wrist rotation. This results in unstable clubfaces, uncontrolled swing paths, and consequently, issues such as right hooks, left hooks, and off-target impact points. The consistency and repeatability of the movements are also poor.

[0003] Secondly, the body's power generation is disconnected from the clubhead movement. Most training methods focus on the active swing of the upper limbs, and the kinetic energy generated by the body rotation cannot be effectively and losslessly transferred to the shaft and clubhead. A large amount of power is lost in the joints such as the wrist and hand, resulting in low swing efficiency and discontinuous power generation when hitting the ball.

[0004] Third, existing golf training equipment cannot provide structural constraints on the torsional force exerted by the hands. Ordinary grips only achieve basic gripping functions and cannot guide trainees to form the correct torque relationship between their hands. Trainees find it difficult to perceive and establish a stable torque balance, and it is difficult to correct the clubface opening state from a physical structure perspective.

[0005] Fourth, training methods that rely on verbal guidance and motion imitation lack a physical forced correction mechanism. Even if trainees understand the theory, they still find it difficult to avoid errors such as hand interference, excessive clubhead lag, and premature wrist release in actual swings. This results in long training cycles and low error correction efficiency.

[0006] Based on the above problems, existing golf training methods and equipment cannot meet trainees' needs for efficient power transfer, stable clubface control, and the establishment of standardized movements. Summary of the Invention

[0007] To address the problems existing in the prior art, this invention provides a golf swing training method. This method is based on a two-way independent torque grip, which achieves automatic clubface stabilization, efficient power transfer, and standardized movement during the golf swing, effectively solving the problem of unstable shots caused by traditional training that relies on hand force and timing control.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a golf swing training method, which uses a dual independent torque grip training device, wherein the dual independent torque grip is set at the grip of the training device; The dual independent torque grip includes a rod-shaped internal support mechanism, a second grip, and a first grip. The second grip and the first grip are respectively arranged and sleeved along the axial direction of the internal support mechanism, allowing the user to hold and use them in the front and back during swinging movements. Torque generating mechanisms are provided between the second grip and the internal support mechanism, and between the first grip and the internal support mechanism. The two torque generating mechanisms enable the second grip and the first grip to be independently twisted relative to the internal support mechanism, and provide torques in opposite directions to the second grip and the first grip. The training method includes the following steps: Grip: The trainee holds the first grip with the left hand and the second grip with the right hand, so that the hands form a separate grip position; Backswing: The trainee uses the inside of the left foot to generate force and the left transverse abdominal muscle to contract, causing the body to passively rotate to the right. At the same time, the left hand applies a leftward torsional torque to the first grip, maintaining the torque continuously. Downswing: Keep the torque in your left hand constant, and use the inside of your right foot and the contraction of your right transverse abdominal muscle to passively rotate your body to the left, and the clubhead will fall due to its own inertia; Torque alignment: During the downswing, the right hand applies a rightward torsional torque to the second grip, so that the torque of the left hand and the torque of the right hand are in a 1:1 ratio, thus achieving torque alignment; Shot: Maintain torque alignment to complete the shot, and rely on the clubhead inertia to naturally complete the follow-through and recovery. The first and second grips can twist independently relative to the shaft and provide torques in opposite directions, allowing the trainee's hands to be separated and not interfere with each other.

[0009] The golf swing training method of the present invention is based on a two-way independent torque grip, which realizes the training effect of automatic clubface stabilization, efficient power transfer and standardized movement during the golf swing, effectively solving the problem of unstable shot caused by traditional training that relies on hand force and timing control.

[0010] In a further technical solution, the training method also includes a method of training using an adjustable counterweight rod head. The adjustable counterweight rod head is the rod head of a training device, and includes a rod head body with an assembly structure for detachably connecting counterweight components. The method of training using an adjustable counterweight rod head includes the following steps: Weighting: Weighting components can be detachably installed on the clubhead body according to training needs to adjust the weight and center of gravity of the clubhead; Weight sensing: Adjust the weight of the clubhead and perform a complete backswing, downswing, torque alignment, and impact to sense the differences in motion caused by weight changes.

[0011] In a further technical solution, the assembly structure includes at least one of a threaded connection structure, a snap-fit ​​connection structure, an adhesive structure, an insert structure, or a magnetic attraction structure.

[0012] In a further technical solution, the assembly structure is located at the bottom of the clubhead body, and the center of gravity of the clubhead body is lowered to enhance the perception of swing inertia.

[0013] In a further technical solution, the torque generating mechanism is at least one of the following: torsion spring, spiral spring, clock spring, rubber elastomer, magnetorheological damper, friction plate, gas spring, and hydraulic torsional damper.

[0014] In a further technical solution, the dual independent torque grip also includes a torque adjustment mechanism, which is used to adjust the magnitude of the torque generated by the torque generating mechanism.

[0015] In a further technical solution, the dual independent torque grips also include a travel limiting mechanism, which is used to limit the travel of the second grip and the first grip torsion, the travel including travel in one or both directions.

[0016] In a further technical solution, the dual independent torque grip also includes a stroke adjustment mechanism, which is used to adjust the stroke of the stroke limit mechanism.

[0017] In a further technical solution, the counterweight component is also provided with an assembly structure for detachable connection with other counterweight components, and at least two of the counterweight components are nested or stacked on the rod head body.

[0018] In a further technical solution, the clubhead body includes a main body, a striking face, a heel, a toe, a bottom, and a top, and the assembly structure is disposed at at least one of the heel, toe, bottom, and top.

[0019] The beneficial effects are: 1. This invention uses independent two-way torque grips for both hands to enable trainees to form a stable torque balance during the swing, structurally ensuring that the clubface is automatically square, significantly reducing the probability of right and left hooks, and greatly improving the stability and consistency of the hitting direction.

[0020] 2. This invention restricts unnecessary hand movements, avoids wrist rotation and active arm force generation, and enables the kinetic energy generated by body rotation to be transferred to the shaft and clubhead without loss or attenuation, significantly improving power transfer efficiency and achieving faster clubhead speed and greater hitting distance under the same force conditions.

[0021] 3. This invention adopts a detachable clubhead weight structure, which can freely adjust the clubhead weight according to the training stage and correction needs. It can specifically enhance the inertial perception, leverage motion feel and swing rhythm, and is suitable for all stages of golf training from beginners to advanced players.

[0022] 4. This invention guides the clubhead to move by inertia, eliminating interference from hand control and making the swing more natural and in line with biomechanical principles. Trainees can achieve stable and repeatable standardized swing movements without relying on complex timing control.

[0023] 5. This invention combines torque structure constraints with the body's force generation mechanism to achieve movement correction from a physical level. It can quickly establish correct swing habits without a lot of repetitive imitation, greatly shortening the training cycle and improving training efficiency. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings: Example

[0027] like Figure 1 As shown, a dual independent torque grip for a golf swing training method includes a rod-shaped internal support mechanism 10, a second grip 20, and a first grip 30. The second grip 20 and the first grip 30 are respectively arranged and sleeved along the axial direction of the internal support mechanism 10, so that the user can hold them back and forth during the swing with both hands. Torque generating mechanisms 40 are provided between the second grip 20 and the internal support mechanism 10, and between the first grip 30 and the internal support mechanism 10. The two torque generating mechanisms 40 enable the second grip 20 and the first grip 30 to be independently twisted relative to the internal support mechanism 10, and provide torques in opposite directions to the second grip 20 and the first grip 30.

[0028] The dual independent torque grips of this invention are mounted on the shaft of an external sports device or integrated with it. The mounting position is consistent with the normal grip position of the user's hands when using the external sports device. The user can grip the external sports device based on the normal grip position. During the preparation stage, the user twists the grips in the opposite direction with both hands, and through the twisting force, the posture of the hands and arms is made to facilitate precise force exertion for striking training. This avoids beginners from not making progress for a long time or developing incorrect force exertion habits due to errors in force exertion and striking, thereby training the user to have correct force exertion and striking habits.

[0029] Example 2, this example is based on Example 1, such as Figure 1 As shown, the internal support mechanism 10 is a hollow rod shape, used to be sleeved on the rod of the external sports equipment.

[0030] In this embodiment, the training device is used as a grip-like device, mounted on the shaft of a regular golf club.

[0031] Example 3, based on Example 1, the internal support mechanism 10 is a solid rod, which is suitable for two-handed gripping and swinging motions.

[0032] In this embodiment, the training device is an integrated piece of equipment with external sports equipment, that is, the training device is equivalent to the sports equipment.

[0033] Example 4, as Figure 2 As shown, this embodiment is based on any of the previous embodiments and is an application example. In this embodiment, the sports equipment is a golf club. The illustrations of this embodiment can demonstrate that the training equipment is mounted on a golf club, or that the training equipment is integrated with a golf club.

[0034] Example 5: This example is based on any of the previous examples. The torque generating mechanism 40 is at least one of the following: torsion spring 41, spiral spring, clock spring, rubber elastomer, magnetorheological damper, friction plate, gas spring, and hydraulic torsional damper.

[0035] Example 6, this example is based on Examples 1-5, in which the torque generating mechanism 40 is a torsion spring 41.

[0036] Example 7, based on Examples 1-5. In this example, the torque generating mechanism 40 between the second grip 20 and the internal support mechanism 10 is a torsion spring 41, and the torque generating mechanism 40 between the first grip 30 and the internal support mechanism 10 is a spiral spring.

[0037] Example 8, based on Examples 1-6, further includes a torque adjustment mechanism, which is used to adjust the magnitude of the torque generated by the torque generating mechanism 40.

[0038] like Figure 5 As shown in the figure, in this embodiment, the torque generating mechanism 40 is exemplified by the torsion spring 41. It can be understood that different torque generating mechanisms 40 can be adapted to different torque adjustment mechanisms, and the same torque generating mechanism 40 can also have more than one torque adjustment mechanism. Here, only the torque generating mechanism 40 is illustrated by the torsion spring 41. Those skilled in the art can know all the torque adjustment methods that can be used with the torsion spring 41, and also know the methods of using torque adjustment mechanisms when using other torque generating mechanisms 40. These mechanisms are all within the protection scope of this application.

[0039] like Figure 5 As shown, for ease of demonstration, in Figure 5 Taking the structure between the second grip 20 and the internal support mechanism 10 as an example, it can be understood that the same torque adjustment mechanism can be set between the first grip 30 and the internal support mechanism 10, or other torque adjustment mechanisms can be selected, which will not be elaborated here.

[0040] A torsion spring 41, also known as a cylindrical helical torsion spring, is sleeved between the internal support mechanism 10 and the second grip 20. One end of the torsion spring 41 is fixedly connected to the inner wall of the second grip 20, and the other end of the torsion spring 41 is connected to the adjusting torsion member 42. The adjusting torsion member 42 can perform a fixed movement around the internal support mechanism 10. That is, under some conditions, the adjusting torsion member 42 is fixed to the internal support mechanism 10, and under some conditions, the adjusting torsion member 42 can move around the circumference of the internal support mechanism 10.

[0041] Specifically, in this embodiment, such as Figure 5 , Figure 6 and Figure 7As shown, the adjusting torsion spring 42 is annular in shape and hollowly sleeved outside the internal support mechanism 10. A torsion adjusting fixing member 13 is fixedly connected to the internal support mechanism 10 corresponding to the adjusting torsion spring 42. An insert 421 is provided on the side of the adjusting torsion spring 42 facing the torsion adjusting fixing member 13, and a groove 131 is provided on the side of the torsion adjusting fixing member 13 facing the adjusting torsion spring 42. At least one groove 131 is provided on the annular surface of the torsion adjusting fixing member 13. With one groove 131, the adjusting torsion spring 42 needs to rotate 360 ​​degrees each time the torque of the torsion spring 41 is adjusted. Alternatively, multiple angle selections during torque adjustment can be achieved by adding grooves 131. Multiple grooves 131 can be provided at fixed or non-fixed angle intervals. In this embodiment, the number of grooves 131 is 12. Furthermore, to increase the connection strength and stability between the adjusting torsion spring 42 and the torsion adjusting fixing member 13, as... Figure 7 As shown, in this embodiment, there are 6 inserts 421. The 6 inserts 421 are arranged in a ring at equal intervals of 60 degrees on the torsion adjusting member 42. The 12 slots 131 are arranged in a ring at equal intervals of 30 degrees on the torsion adjusting member 13. With this arrangement, the minimum rotation angle of the torsion adjusting member 42 is 30 degrees, and each rotation angle is a multiple of 30 degrees, which ensures that the 6 inserts 421 can be inserted into the corresponding slots 131.

[0042] In this embodiment, since the torque rotating component itself is small, a torque operation knob is fixedly connected to the torque rotating component for easy operation.

[0043] The aforementioned adjustment of the torsional actuator 42 under certain conditions, which is fixed to the internal support mechanism 10, and the adjustment of the torsional actuator 42 under certain conditions, which can move around the circumference of the internal support mechanism 10, can be explained as follows: By lifting the torque operation knob with a finger, the insert 421 of the torque adjusting member 42 can be pulled out of the groove 131 of the torque adjusting member 13, such as... Figure 6As shown, after the adjusting torque actuator 42 is pulled out, the condition for the adjusting torque actuator 42 to move around the circumference of the internal support mechanism 10 is met. At this time, the adjusting torque actuator 42 can be rotated by rotating the torque operation knob, which drives one end of the torsion spring 41 to rotate around the internal support mechanism 10, changing the preload angle of the torsion spring 41. This achieves the adjustment of the torque provided by the torsion spring 41 to the second grip 20. It can be understood that a scale and indicator can also be set on the end face of the second grip 20 and the torque operation knob 422 in the product to indicate the size of the torque adjustment. After the rotation angle of the adjusting torsion member 42 meets the torque adjustment requirements, the adjusting torsion member 42 can be displaced along the axial direction of the internal support mechanism 10 by pressing the torque adjustment operation knob 422, so that the insert 421 of the adjusting torsion member 42 is inserted into the groove 131 of the adjusting torsion fixing member 13, thus achieving the condition that the adjusting torsion member 42 is fixed to the internal support mechanism 10. At this time, the adjusting torsion member 42 and the internal support mechanism 10 can no longer be displaced at an angle, and are considered to be fixed.

[0044] Example 9, this example is based on Examples 1-6 or Example 8, such as Figure 5 and Figure 6 As shown, it also includes a travel limit mechanism for limiting the travel of the second grip 20 and the first grip 30 to the twist, which includes travel in one or both directions.

[0045] This section explains the travel in one or two directions. In the case of embodiments 1-6, if there is no mandatory requirement for the torque generating mechanism 40, the travel limit mechanism may not be provided. In the case of embodiment 8, since the torque adjustment mechanism may cause the torque generating mechanism 40 to generate an initial torque, it is necessary to provide a travel limit mechanism in the opposite direction of the torque on the second grip 20, even if the second grip 20 cannot be twisted in the opposite direction. This is a travel limit mechanism that includes a travel limit in one direction, and a separate embodiment will not be listed here.

[0046] In this embodiment, the travel limit mechanism restricts the travel in two directions, such as... Figure 5 and Figure 6 As shown, two limiting blocks 14 are provided on one circumferential surface of the internal support mechanism 10, and a mating block 21 is provided between the two limiting blocks 14. The mating block 21 is fixedly connected to the inner wall of the second grip 20. That is, when the second grip 20 rotates around the internal support mechanism 10, it moves the mating block 21 within the angle defined by the two limiting blocks 14. When the second grip 20 twists the angle so that the mating block 21 contacts one of the limiting blocks 14, the end point of the stroke of the second grip 20 is reached, which is the limitation in two directions.

[0047] The reverse limit is set to maintain the initial torque of the torque generating mechanism 40 and to prevent the user from twisting the second grip 20 in the opposite direction due to lack of skill, thus preventing the torque generating mechanism 40 from generating the corresponding torque and achieving the desired training effect. The positive limit is set to prevent the user from over-twisting, as an excessively large twisting angle is detrimental to the user's ability to exert force. In this embodiment, by setting limits in two directions, both the user's ability to twist in the opposite direction and the appropriate angle for twisting in the correct direction are ensured, further facilitating user practice.

[0048] Those skilled in the art will understand that both unidirectional and bidirectional limiting can be implemented in other structural forms. For example, a ratchet mechanism can be used for unidirectional limiting, and a structure can be used for bidirectional limiting through a notched ring, allowing the mating block 21 to move within the notch of the ring. Those skilled in the art can select a suitable stroke limiting mechanism based on the selection of the torque generating mechanism 40 and the torque adjusting mechanism. In this embodiment, the internal structure of the second grip 20 and the internal support mechanism 10 is used as an example. It is understood that the same stroke limiting mechanism can be set between the first grip 30 and the internal support mechanism 10, or different stroke limiting mechanisms can be set. This will not be elaborated further here.

[0049] Example 10, based on Example 9, further includes a stroke adjustment mechanism, which is used to adjust the stroke size of the stroke limit mechanism.

[0050] like Figure 8 As shown, in this embodiment, the structure between the second grip 20 and the internal support mechanism 10 is taken as an example. When the second grip 20 rotates, the direction of the torque generated by the torque generating mechanism 40 is defined as the first direction, and the direction of the torque generated against the torque generating mechanism 40 is defined as the second direction. Among the two limiting blocks 14, the one in the first direction of the mating block 21 is the first limiting block 141, and the one in the second direction of the mating block 21 is the second limiting block 142. Since the first limiting block 141 ensures the initial position of the mating block 21, i.e., the second grip 20, and is irrelevant to the normal torsional movement of the second grip 20, in this embodiment, the first limiting block 141 is fixed, and the second limiting block 142 can perform a fixed movement around the internal support mechanism 10. That is, under some conditions, the second limiting block 142 is fixed to the internal support mechanism 10, and under some conditions, the second limiting block 142 can move around the circumference of the internal support mechanism 10.

[0051] In this embodiment, the stroke adjustment mechanism includes a stroke rotating member 15, which is annular in shape and hollowly fitted outside the internal support mechanism 10. The second limiting block 142 is fixedly connected to the stroke rotating member 15. At least two stroke positioning holes 16 are provided at fixed or non-fixed angle intervals on one circumferential surface of the internal support mechanism 10. The stroke rotating member 15 is positioned between the stroke positioning pin 17 and the stroke positioning holes 16. The number of stroke positioning holes 16 is the number of positions that the stroke rotating member 15 can be positioned at, which is the number of positions that the stroke adjustment mechanism can adjust. In this embodiment, the number of stroke positioning holes 16 is 5. The 5 stroke positioning holes 16 are arranged at equal intervals of 24 degrees on the surface of the internal support mechanism 10. That is, the minimum unit of stroke adjustment is 24 degrees. It can be understood that the stroke positioning holes 16 do not need to be fully covered on the internal support mechanism 10, because for most people, the twisting angle of holding the second grip 20 to the optimal force position is not too large. Setting different stroke ranges is only to adjust within a small range to match different people, and there is no need for very large angle stroke adjustment.

[0052] In this embodiment, since the stroke rotating component 15 is relatively small, a stroke operation knob 151 is fixedly connected to the stroke rotating component 15 for easy operation. The stroke positioning pin 17 is inserted through a positioning platform protruding from the stroke operation knob 151. The axial position of the stroke positioning pin 17 in the internal support mechanism 10 corresponds to the stroke positioning hole 16.

[0053] The preceding statement regarding the second limiting member being fixed to the internal support mechanism 10 under certain conditions, and the second limiting member being able to move around the circumference of the internal support mechanism 10 under certain conditions, can be explained as follows: By lifting the travel positioning pin 17 with a finger, the travel positioning pin 17 can be pulled out of the travel positioning hole 16. After the travel positioning pin 17 is pulled out, the condition for the second limit block 142 to move around the circumference of the internal support mechanism 10 is met. At this time, the second limit block 142 can be rotated by rotating the travel operation knob 151. The rotation of the second limit block 142 changes the size of the angle between the second limit block 142 and the first limit block 141, and changes the size of the rotation travel of the mating block 21, i.e., the second grip 20. Thus, the size of the rotation travel of the second grip 20 is adjusted. It can be understood that an indicator can also be placed at the travel positioning hole 16 of the internal support mechanism 10 in the product to indicate the size of the travel. After the second limit block 142 rotates to meet the stroke adjustment requirements, the stroke positioning pin 17 can be pressed to insert the stroke positioning pin 17 into the corresponding stroke positioning hole 16, thus achieving the condition that the second limit block 142 is fixed to the internal support mechanism 10. At this time, the second limit block 142 and the internal support mechanism 10 can no longer make angular displacements and are considered fixed.

[0054] It is understood that this embodiment is a further embodiment of stroke adjustment based on two limit blocks 14 to achieve stroke limit. Those skilled in the art will know that appropriate stroke adjustment mechanisms can be adopted in different mechanisms for achieving stroke limit. This is only an illustration of a simple and clear embodiment and does not represent a limitation on the stroke adjustment mechanism in terms of protection scope.

[0055] In this embodiment, an example of maintaining the rotational stability of the second grip 20 is also provided. A bearing 22 is provided between the second grip 20 and the internal support mechanism 10, and the bearing 22 is used to achieve stable torsion of the second grip 20. It is understood that other structural forms can also be used to achieve stable torsion of the second grip 20, which will not be described in detail here.

[0056] Example 11: This example is based on any of the previous examples, and the outer surfaces of the second grip 20 and the first grip 30 are provided with textured rubber layers.

[0057] By incorporating a textured rubber layer, the friction and comfort of the user's hands when gripping the second grip 20 and the first grip 30 are improved.

[0058] Example 12, which is based on Example 2 or any example based on Example 2, further includes an installation mechanism for assembling and disassembling the internal support mechanism 10 from the rod of the external motion device.

[0059] In this embodiment, as Figure 4 As shown, the installation mechanism includes a soft inner tube 11 and an internal support mechanism 10 including a rigid support tube 12. The soft inner tube 11 is made of rubber, and the rigid support tube 12 is made of a hard metal such as stainless steel. Both the soft inner tube 11 and the rigid support tube 12 are hollow tubes. The outer wall of the soft inner tube 11 is a cylindrical surface of constant diameter, that is, its outer diameter remains constant along the axial direction. The inner wall of the rigid support tube 12 is a matching cylindrical surface. The outer wall of the soft inner tube 11 is provided with spiral ribs, and the inner wall of the rigid support tube 12 is provided with spiral grooves that are adapted to the spiral ribs. The rest of the structure remains unchanged. That is, the second grip 20 and the first grip 30 are respectively set on the rigid support tube 12 through a torque generating mechanism 40.

[0060] During installation, first, the soft inner tube 11 is fitted onto the original grip of the external exercise equipment's shaft, and the soft inner tube 11 is fixed using glue or other methods. Then, the rigid support tube 12 is rotated so that the spiral groove on its inner wall engages with the spiral ribs on the outer wall of the soft inner tube 11, thus fitting onto the outside of the soft inner tube 11 and forming a detachable connection. In the engaged state, the spiral ribs are compressed and fitted into the spiral groove, achieving circumferential anti-rotation, axial limiting, and sealing. After assembly, it can be used for training.

[0061] When it is necessary to disassemble or replace this device, the rigid support tube 12 can be separated from the soft inner tube 11 by twisting the rigid support tube 12 in the opposite direction. The rigid support tube 12 can then be removed, and the soft inner tube 11 can be cut with a knife to achieve disassembly.

[0062] The installation mechanism allows for easy assembly and disassembly of the device, making it convenient for users to replace or disassemble the device according to training progress or wear and tear.

[0063] Example 13, this example is based on Example 12, such as Figure 4 As shown, the inner wall of the soft inner tube 11 is a frustum-shaped inner wall, with a larger inner diameter at one end and a smaller inner diameter at the other end along the axial direction, and the whole has a single taper gradient. The soft inner tube 11 has a spliced ​​structure, and the side wall of the soft inner tube 11 has a cut that runs through both ends, and the two side walls of the cut have mutually matching serrated interlocking interfaces.

[0064] Because the shape of the club shaft used in the swing motion may not be a uniform cylindrical surface—for example, the shaft of a golf club is tapered, with a larger outer diameter at the grip end and a smaller outer diameter near the striking end—it takes considerable force to pry open the smaller end of the soft inner tube 11 and fit it into the end of the golf club when installing it. This makes installation difficult. Therefore, the soft inner tube 11 is designed as a modular structure. During installation, the soft inner tube 11 can be inserted from the side of the golf club rather than the end through a through cut. Using glue or other materials, the cut of the soft inner tube 11 is aligned and fixed, and then the rigid support tube 12 is screwed in to complete the installation.

[0065] In this embodiment, an example is also provided for preventing the soft inner tube 11 from axially moving on the golf club when the rigid support tube 12 is screwed in. A blocking ring is provided on the end face of the soft inner tube 11 corresponding to the end of the golf club. The material of the blocking ring is the same as that of the soft inner tube 11. When the soft inner tube 11 is assembled, the blocking ring is simultaneously assembled on the end face of the golf club. The presence of the blocking ring ensures the axial position of the soft inner tube 11 on the golf club.

[0066] Example 14, which is based on Example 2 or any example based on Example 2, further includes an installation mechanism for assembling and disassembling the internal support mechanism 10 and the rod of the external motion device.

[0067] The mounting mechanism is a clamping clamp located at the end of the internal support mechanism 10, which enables the fixing and disassembly of the internal support mechanism 10 and the rod of the external motion device.

[0068] Example 15: An adjustable weight clubhead for a golf swing training method, such as... Figure 9As shown, it includes a pole head body 50, on which an assembly structure is provided. The assembly structure is used to detachably connect the counterweight component.

[0069] When using the training golf club of the present invention, the practitioner can disassemble and assemble the weight components according to the assembly structure to change the weight of the clubhead body 50, and conduct golf ball training with different clubhead weights, without the need to configure multiple golf clubs.

[0070] In this embodiment, as Figure 10 As shown, the assembly structure is a threaded connection structure.

[0071] In this embodiment, as Figure 10 As shown, there are three counterweight components, which are stacked on the rod head body 50. The three counterweight components are also equipped with assembly structures. Specifically, first mounting holes are opened on the rod head body 50 and the first stacked layer 57, and the first stacked layer 57 is disassembled and assembled by screws and threads. Second mounting holes are opened on the first stacked layer 57 and the second stacked layer 58, and the second stacked layer 58 is disassembled and assembled by screws and threads in the second mounting holes. Third mounting holes 531 are opened on the second stacked layer 58 and the third stacked layer 59, and the third stacked layer 59 is disassembled and assembled by screws and threads in the third mounting holes 531.

[0072] In this embodiment, the assembly structure is located at the bottom of the rod head body 50, that is, all three counterweight components are detachably located at the bottom of the rod head body 50.

[0073] In this embodiment, the user can choose from four clubhead weights: single clubhead body 50, clubhead body 50 plus first stacking layer 57, clubhead body 50 plus first stacking layer 57 plus second stacking layer 58, and clubhead body 50 plus first stacking layer 57 plus second stacking layer 58 plus third stacking layer 59, for a total of four options.

[0074] In this embodiment, the counterweight component and the opposing plane of the rod head body 50 are in contact with each other. In this embodiment, the opposing plane of the counterweight component and the opposing plane of the rod head body 50 are curved surfaces that are in contact with each other, so as to improve the overall stability and tightness of the assembly.

[0075] In this embodiment, the assembly structure is located at the bottom of the clubhead body 50, that is, the first stacking layer 57, the second stacking layer 58 and the third stacking layer 59 are stacked sequentially at the bottom of the clubhead body 50. The counterweight component is located at the bottom of the clubhead body 50, so that the added weight is added at the bottom of the clubhead body 50, which shifts the center of gravity of the clubhead body 50 downward rather than upward. This makes it easier for the trainee to practice correctly for the swing action with a lower center of gravity.

[0076] Example 16, as Figure 11 As shown, this embodiment is based on embodiment 15. The difference between this embodiment and embodiment 1 is that the three counterweight components are independently and detachably mounted on the rod head body 50 through the assembly structure. That is, the first counterweight block 54, the second counterweight block 55 and the third counterweight block 56 are independently and detachably connected to the rod head body 50. In this embodiment, the first counterweight block 54, the second counterweight block 55 and the third counterweight block 56 are each connected to the rod head body 50 through a mounting hole.

[0077] Understandably, in order to reduce the impact on the center of gravity, the second counterweight 55 located in the middle is preferred for counterweighting.

[0078] It is understood that in this embodiment, the first counterweight 54, the second counterweight 55 and the third counterweight 56 ​​are all embedded in the bottom of the clubhead body 50, so as to avoid their influence on the hitting surface of the clubhead body 50.

[0079] Example 17: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the counterweight component and the rod head body 50 are detachably connected by a snap-fit ​​connection structure. Specifically, a male buckle and a female buckle are respectively provided between the counterweight component and the rod head body 50, or they can be elastic claws and slots. The counterweight component and the rod head body 50 are assembled and disassembled through the snap-fit.

[0080] Example 18: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the counterweight component and the rod head body 50 are detachably connected through an assembly structure with an adhesive structure. Specifically, adhesive surfaces are provided between the counterweight component and the rod head body 50, and the assembly and disassembly are performed through the adhesive surfaces. The adhesive surfaces can be Velcro.

[0081] Example 19: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the counterweight component and the pole head body 50 are detachably connected through an embedded assembly structure. Specifically, an embedding groove is opened on the pole head body 50, and the counterweight component with the same shape as the embedding groove is directly embedded into the embedding groove to achieve installation.

[0082] Example 20: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the counterweight component and the rod head body 50 are detachably connected through a magnetic assembly structure. Specifically, magnetic heads with opposite magnetic poles are respectively provided on the opposite surfaces of the dry body and the counterweight component. The connection between the counterweight component and the body is achieved through the principle of mutual attraction between opposite magnetic poles.

[0083] Example 21: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the assembly mechanism of the counterweight component and the rod head body 50 adopts the assembly structure of at least two of the previous embodiments to achieve a detachable connection. Specifically, it can be magnetic attraction plus embedding, that is, a magnetic head is provided in the embedding groove and a magnetic head is provided at the corresponding position of the counterweight component. At the same time as embedding, the connection is further enhanced by magnetic attraction.

[0084] It is understood that other feasible assembly structures can also be used for combination.

[0085] Example 22: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the number of counterweight components is set to 2.

[0086] Understandably, based on the distinction between independent and stacked or nested configurations, the number of counterweight components and the number of selectable clubhead weights do not always follow a one-to-one pattern. In embodiments where counterweight components are assembled independently, there are more options for clubhead weights.

[0087] Example 23: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the number of counterweight components is set to 4.

[0088] Understandably, based on the difference between independent and stacked configurations, the number of counterweight components and the number of selectable clubhead weights do not always follow a rule of increasing by 1. In embodiments where counterweight components are assembled independently, there are more options for clubhead weights.

[0089] Example 24: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the assembly structure is set at the heel of the clubhead body 50, that is, at the end of the clubhead body 50 near the club grip.

[0090] Example 25: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the assembly structure is located at the toe of the clubhead body 50, that is, at the farthest end of the clubhead body 50 away from the club grip.

[0091] Example 26: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the assembly structure is set at the bottom of the club head body 50, that is, the bottom surface of the club head body 50 that contacts the ground.

[0092] It is understood that those skilled in the art can select the position of the assembly structure based on the different shapes of the counterweight components and the assembly structure, as well as the differences in the shape of the pole head body 50.

[0093] Example 27: This embodiment is based on any of the previous embodiments. The difference between this embodiment and any of the previous embodiments is that the assembly structure is set on the rod head body 50 at at least two positions including those in Embodiment 1, Embodiment 24, Embodiment 25, and Embodiment 26.

[0094] Example 28: The difference between this embodiment and the previous embodiment is that the number of counterweight components is one.

[0095] Example 29: This embodiment is based on embodiment 15. The difference between this embodiment and embodiment 15 is that, as Figure 12 As shown, the first nesting layer 51, the second nesting layer 52 and the third nesting layer 53 are nested in sequence outside the clubhead body 50, and the first nesting layer 51, the second nesting layer 52 and the third nesting layer 53 are all semi-enclosed nesting, and the flat surface of the clubhead body 50 is the hitting surface.

[0096] Example 30: The difference between this embodiment and the previous embodiment is that the assembly structure is located on the top of the rod head body.

[0097] In this embodiment, to avoid affecting training by influencing the center of gravity of the clubhead, the assembly structure should be designed to minimize or even eliminate the impact on the center of gravity of the clubhead. For example, an insert structure can be selected, with an insert groove on the top of the clubhead. When the counterweight is inserted into the insert groove, the center of gravity of the clubhead remains unchanged or changes very little. That is, the center of gravity of the counterweight is located at or as close as possible to the original center of gravity of the clubhead, thereby reducing the impact on the center of gravity of the clubhead.

[0098] Example 31: In the preceding embodiments, the dual independent torque grip and adjustable weight clubhead of the golf swing training method of the present invention were described in detail. This embodiment is based on the dual independent torque grip of any of the preceding embodiments.

[0099] A golf swing training method, wherein the dual independent torque grips are disposed at the grip of the training device; The training method includes the following steps: Grip: The trainee holds the first grip with the left hand and the second grip with the right hand, so that the hands form a separate grip position; Backswing: The trainee uses the inside of the left foot to generate force and the left transverse abdominal muscle to contract, causing the body to passively rotate to the right. At the same time, the left hand applies a leftward torsional torque to the first grip, maintaining the torque continuously. Downswing: Keep the torque in your left hand constant, and use the inside of your right foot and the contraction of your right transverse abdominal muscle to passively rotate your body to the left, and the clubhead will fall due to its own inertia; Torque alignment: During the downswing, the right hand applies a rightward torsional torque to the second grip, so that the torque of the left hand and the torque of the right hand are in a 1:1 ratio, thus achieving torque alignment; The specific 1:1 control depends on the travel and maximum value settings of the first and second grips.

[0100] Shot: Maintain torque alignment to complete the shot, and rely on the clubhead inertia to naturally complete the follow-through and recovery. The first and second grips can twist independently relative to the shaft and provide torques in opposite directions, allowing the trainee's hands to have separate torques without interfering with each other. It is important to emphasize that in the traditional golf swing, trainees lack restraint. When using their hands to exert force, their wrists are prone to loosening, twisting, and shaking. These factors are transmitted to the clubhead, causing it to be dragged, lagging, and wobbling, ultimately resulting in a slow, off-target, and weak shot.

[0101] In the steps of this invention, a complete hitting sequence consists of backswing, downswing, torque alignment, and impact. During the impact, a 1:1 symmetrical torque balance between the left and right hands is achieved through dual independent torque grips. After forced constraint, the wrists themselves will no longer exert force to interfere with the shaft, resulting in a stable, straight, and smooth shaft movement. The clubhead movement is not subject to resistance from the shaft, and the clubhead achieves a more efficient and stable hit under the force of its own weight and the rotation of the trainee's body.

[0102] In the steps of this invention, torque alignment ensures that the force generated by the trainee's body rotation can be transmitted to the clubhead. In ordinary training scenarios, the trainee's wrists are loose, and the force of body rotation is dissipated or delayed at the wrists. In the torque alignment of this invention, the opposing torques of both hands are the same, and the grip and the shaft can be regarded as forming a rigid body. The wrists are no longer loose and dissipate force, and structural support is formed at the wrists. Therefore, the trainee's body rotation movement carries the shaft without damage.

[0103] The training method of this invention aims to help trainees experience the correctness of body force generation and wrist rotation, eliminating unnecessary hand and wrist movements. Through structural constraints, a stable body force generation structure is established, linking body force generation with clubhead movement. This is achieved through dual independent torque grips, which force trainees to perform a correct shot. Trainees can clearly feel a significant improvement in shot performance. Under such training, trainees can gradually develop good habits of body rotation and wrist control, and ultimately maintain correct body rotation and wrist control even after leaving the training equipment.

[0104] Example 32: This embodiment is based on embodiment 31. The training method further includes a method for training using an adjustable counterweight rod head. The adjustable counterweight rod head is the rod head of a training device. The adjustable counterweight rod head includes a rod head body, and the rod head body is provided with an assembly structure for detachably connecting the counterweight components. The method for training using an adjustable counterweight rod head includes the following steps: Weighting: Weighting components can be detachably installed on the clubhead body according to training needs to adjust the weight and center of gravity of the clubhead; Weight sensing: Adjust the weight of the clubhead and perform a complete backswing, downswing, torque alignment, and impact to sense the differences in motion caused by weight changes.

[0105] Specifically, the first stage involves setting a relatively light weight for the club. In this stage, the user supports the club's load with the lower part of their right index finger, using their right middle and ring fingers to control the clubhead's descent. Simultaneously, the left palm forms a stable point of force, allowing for a complete backswing, downswing, torque alignment, and impact motion. Next, the weight of the clubhead is increased from this initial stage to a second stage, a relatively heavier weight. This increases the overall load on the club, strengthening the support point on the lower part of the right index finger and increasing the difficulty of maintaining the force point with the left palm. Under this increased load, the user must maintain the support point formed by their right index finger, control the clubhead's descent with their middle and ring fingers, and stably maintain the force point with their left palm, completing this intensive training. Comparing the first and second stages allows the user to perceive the differences in club descent speed, clubhead lag, and the effect of vertical drop, enhancing and reinforcing the feeling of correct movement.

[0106] Beyond the striking phase, this invention also incorporates two steps: weight adjustment and weight sensing. This involves adjusting the weight of the clubhead outside of the striking phase, allowing the user to feel the clubhead following the correct shaft motion under its own weight during the downswing, thus experiencing the correct clubhead movement. Combined with weight adjustment and weight sensing, this enables the user to more acutely perceive the correct clubhead swing, further enhancing their awareness of body rotation and wrist control.

[0107] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
