Description

Technical Field

[0001] This invention relates to the field of dance equipment technology, specifically to a support and protection structure and method for practicing street dance moves. Background Technology

[0002] Street dance is a dance that combines sports and street performance. It uses physical movements as its basic content, accompanied by street dance music, and can be performed solo or in groups. It is a sport that has both entertainment and fitness benefits as well as performance value. In university campuses, many dance clubs organize to practice street dance. It is even more common for middle school students to engage in street dance activities in their spare time. They have formed a unique community culture among teenagers in residential communities in major cities. And handstands are one of the compulsory courses for most street dancers.

[0003] In the prior art, patent publication number "CN113577737A" discloses a street dance movement assistive training device, which is also a common structure used in training venues. This street dance movement assistive training device includes a support assembly and a suspension assembly. The support assembly includes a chassis, support column, top frame, and rotating plate. The suspension assembly includes hooks, a main hanging rope, connecting buckles, multiple side hanging ropes, and multiple straps. The support assembly provides support for the suspension assembly, which has rotatable hanging ropes and multiple straps. This device provides a certain degree of support for beginners in street dance.

[0004] As can be seen from the existing technology, some current street dance assistive devices do not take into account the strength control of beginners. Most of them simply provide support without correcting the user's movements. They still require professional assistance, which leads to the waste of teaching resources and high learning costs. Furthermore, it may cause beginners to have insufficient strength, perform inadequate movements, or have incorrect postures. For example, in street dance, movements such as bending over, Nike, and crane poses have a large range of motion and require greater support strength. Without professional guidance, they are more prone to injury. Therefore, there is an urgent need for a support and protection structure for street dance practice to overcome the common problems of street dance learners and reduce beginners' fear of high-difficulty movements. Summary of the Invention

[0005] This application provides a support and protection structure and method for practicing street dance moves, with the main purpose of solving the problems of difficult-to-perform moves, danger, and the need for professional assistance.

[0006] To achieve the above objectives, the first aspect of this application provides a support and protection structure and method for practicing street dance moves, comprising:

[0009] The telescopic movement mechanism consists of three parts, corresponding to the two legs and waist of the human body respectively. Each telescopic movement mechanism is also equipped with a fixing mechanism at its bottom for connecting to the waist and legs of the human body.

[0010] In one feasible implementation, the support mechanism includes: a base plate and a telescopic plate, the telescopic plate being fixedly mounted vertically at the middle of one side of the top of the base plate, and a set of inclined support rods connected to the outer wall of the bottom end of the telescopic plate and abutting against the ground; a top plate, the top plate being fixedly connected horizontally to the top of the telescopic plate and located directly above the base plate, the top plate having multiple sliding grooves, one end of the sliding groove near the telescopic plate being a limiting end; fixed columns, the multiple fixed columns being fixedly mounted in pairs on both sides of the limiting end of the sliding groove; and a cylinder, the cylinder being fixedly mounted at the top edge of the top plate and arranged parallel to the sliding groove, the cylinder being connected to the control switch.

[0011] In one feasible embodiment, the locking mechanism includes: three sliding seats, each of which is movably engaged in the sliding groove; a rotating column, which is rotatably mounted on the top center of the sliding seat via a torsion spring, and a limiting plate is fitted on the outer wall of the rotating column, with both ends of the limiting plate extending to the outer side of the sliding seat; a fixed box, which is fixedly mounted on the sliding seat, and a sliding column is disposed in the fixed box, with the outer end of the sliding column abutting against the rotating column and the inner end of the sliding column abutting against the spring; and a pushing plate, which is rotatably connected in the inner cavity of the fixed box, with a portion of its position coinciding with the travel range of the sliding column, and a horizontal moving plate rotatably connected to the bottom end of the pushing plate, the other end of which extends to the inner side of the telescopic moving mechanism.

[0012] In one feasible implementation, the multiple limiting plates are of equal length, and the two ends of the limiting plates are provided with connecting grooves in opposite positions. The multiple limiting plates are connected by the connecting grooves at both ends, and one of the limiting plates corresponds to the telescopic end of the cylinder.

[0013] In one feasible embodiment, the telescopic moving mechanism includes: an upper sleeve, which is fixedly connected to the bottom end of the sliding seat. The upper sleeve is hollow, and a middle sleeve and a lower sleeve are sequentially inserted into its inner side. A limiting component is provided on the inner wall of the contacting side of the upper sleeve, middle sleeve, and lower sleeve. The top end of the limiting component is the driving end of the limiting component, and the driving end matches the position of the moving plate. A fixing mechanism is rotatably connected to the bottom end of the lower sleeve. A limiting notch and a sliding notch are provided. The limiting notch is opened at the middle position on both sides of the bottom end of the lower sleeve, and the sliding notch is opened adjacent to the limiting notch.

[0014] In one feasible embodiment, the limiting assembly includes a mounting groove on the inner wall of the middle sleeve and the lower sleeve, and further includes: a sliding plate, which is movably engaged with the bottom end of the inner wall of the middle sleeve and the outer sleeve in a horizontal direction, one end of the sliding plate being engaged in the mounting groove, and the other end of the sliding plate being connected to a second spring; a connecting strip, which is movably disposed in the mounting groove in a vertical direction, the top end of the connecting strip being in a hollow state, and a sliding block and a third spring being disposed on its inner side; and a rotating inclined plate, several of which are movably disposed in the mounting groove, one end of which is rotatably connected to the two side walls of the connecting strip through a strip groove, the outer end of the rotating inclined plate being an inclined surface, and the outer end of the rotating inclined plate also having a pin movably connected to the inner wall of the mounting groove.

[0015] In one feasible implementation, the outer bottom end of the sliding block is engaged above the mounting groove, and all the sliding blocks correspond to the position of the push plate.

[0016] In one feasible implementation, the fixing mechanism includes: a rotating support plate, which is rotatably connected to the bottom end of the lower sleeve, and a connecting block is also connected to the outside of the rotating support plate, with a leg collar or waist collar connected to the outside of the connecting block; and a telescopic block, which is telescopically disposed on the outer wall of the rotating support plate by another cylinder and located in the sliding notch or limiting notch.

[0017] In one feasible implementation, the fixing mechanism further includes: a telescopic cylinder, which is movably connected to the bottom side wall of the lower sleeve via a spherical joint and a connecting ball, the connecting ball being provided with a polygonal protrusion; and a track, which is formed on the inner wall of the spherical joint and is movably fitted onto the outside of the polygonal protrusion.

[0018] The second aspect of this application provides a method of using a support and protection structure for practicing street dance moves as described in the first aspect, comprising the following steps:

[0019] The worker stands on the base plate and secures their body with leg and waist loops. They then lean forward to begin the inversion, moving their legs upwards to retract the lower and middle sleeves, preventing them from falling over via a limiting component. Once the inversion is complete, all locking mechanisms move to the limiting end, where they are held in place by an electromagnet. Upon completion of the inversion, the worker uses a control button to move an electric push rod, releasing the limiting components and changing the tilt angle to help them return to an upright position.

[0020] The support and protection structure and method for practicing street dance movements provided in this application have at least the following beneficial effects:

[0021] 1. The support and protection structure for street dance movement practice provided in this application is an auxiliary protection device for street dance beginners. It is especially suitable for learners to practice common inverted postures in street dance. It can be practiced and trained under the premise of safety. The device includes a support mechanism, a locking mechanism and a telescopic movement mechanism. The bottom of the telescopic movement mechanism is also equipped with a fixing mechanism. The support mechanism is a frame with an activity area for the human body to perform inverted postures. The top of the area is equipped with a locking mechanism. Together with the telescopic movement mechanism, it allows learners to perform inverted posture training in this area. The user is connected to the waist and legs of the human body through the fixing mechanism to restrict the activity area and prevent tilting movements. It also ensures that learners do not suffer from improper control of force during inverted postures, such as bending over, falling over, or standing on their backs.

[0022] 2. This device also provides a switch that users can control themselves. During training, with the assistance of this device, users can maintain an inverted posture for a period of time to achieve the training effect. In addition, when in the posture holding phase, the displacement function of the parts in contact with the human body will be restricted, preventing injury from multiple aspects, reducing the difficulty of the user's movement, providing sufficient assistance and support, and overcoming psychological fear. When the user stops training, they can release all restrictions by controlling the switch and help the user slowly return to a standing position. It can play a good supporting and protective role throughout the training process. Attached Figure Description

Detailed Implementation

[0040] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0041] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0042] Please see Figures 1-17 As shown, the first aspect of this application provides a support and protection structure for practicing street dance moves, including: a support mechanism 1, a locking mechanism 2, and a telescopic movement mechanism 3; the support mechanism 1 has an active area, and a control switch 107 is provided in the active area for opening or releasing the body limit control; multiple locking mechanisms 2 are movably arranged on the top of the support mechanism 1 via slide grooves, and the bottom end of the locking mechanism 2 is also connected to the telescopic movement mechanism 3; wherein, the number of telescopic movement mechanisms 3 is three, corresponding to the two legs and waist of the human body respectively, and the bottom end of each telescopic movement mechanism 3 is also provided with a fixing mechanism 4 for connecting to the waist and legs of the human body.

[0043] As can be seen from the above technical solution, the support and protection structure for street dance movement practice provided by this application, as an auxiliary protection device for street dance beginners, is especially suitable for learners to practice common inverted postures in street dance. It can be practiced and trained under the premise of safety. The device includes a support mechanism 1, a locking mechanism 2, and a telescopic movement mechanism 3. The bottom of the telescopic movement mechanism 3 is also provided with a fixing mechanism 4. The support mechanism 1 is a frame in general, with an activity area for the human body to perform inverted postures. The top of the area is provided with a locking mechanism 2. Together with the telescopic movement mechanism 3, it enables learners to perform inverted posture training in this area. The user is connected to the waist and legs of the human body through the fixing mechanism 4, which restricts the activity area to prevent tilting movements and ensures that learners do not suffer from improper force control during the inverted posture, resulting in bending, slouching, or other situations.

[0044] In addition, the device also provides a switch 107 that can be controlled by the user. During training, with the assistance of the device, the user can maintain an inverted posture for a period of time to achieve the training effect. When in the posture holding stage, the displacement function of the components in contact with the human body will be restricted, preventing injury to the user in many ways, while reducing the difficulty of the user's movement and providing sufficient assistance. When the user stops training, he / she can control the switch 107 to contact all the limits and help the user slowly return to the standing position.

[0045] Please see Figures 1-7 As shown, in some examples, the support mechanism 1 further includes: a base plate 101, a support rod 102, a telescopic plate 103, a top plate 104, fixed columns 105, a cylinder 106, and a control switch 107; the telescopic plate 103 is fixedly installed vertically at the middle of one side of the top of the base plate 101, and a set of inclined support rods 102 are connected to the bottom outer wall of the telescopic plate 103 and abut against the ground; the top plate 104 is fixedly connected horizontally to the top of the telescopic plate 103 and is located directly above the base plate 101, and multiple sliding grooves are provided on the top plate 104, with one end of the sliding groove near the telescopic plate 103 being a limiting end; multiple fixed columns 105 are fixedly installed in pairs on both sides of the limiting end of the sliding groove; the cylinder 106 is fixedly installed at the top edge of the top plate 104 and arranged parallel to the sliding groove, and the cylinder 106 is connected to the control switch 107.

[0046] It is understood that the support mechanism 1 includes a base plate 101, which allows people to stand or invert. The base plate 101 is provided with a support rod 102 and a telescopic plate 103. The telescopic plate 103, through the support rod 102, enhances the overall stability of the device. The telescopic plate 103 is an electrically telescopic element or a manually controlled telescopic structure. On the one hand, it can adaptively adjust the activity area in the device according to the height of the human body. On the other hand, when it is retracted to the lowest state, it can reduce the space occupied by the device and facilitate storage. The top plate 104 corresponds to the position of the base plate 101.

[0047] In addition, the top plate 104 is equipped with a fixing post 105 and a cylinder 106. The fixing post 105 is made of metal and can be fixed and attracted to the electromagnet. The cylinder 106 is used to push all the locking mechanisms 2 from the limit end to the other end. Under the control of the control switch 107, the cylinder 106 pushes all the locking mechanisms 2 to move. With the push assistance of the cylinder 106, the human body can return to the upright position from the side that was flipped up from the upside down.

[0048] Please see Figure 1-9 As shown, in some examples, the locking mechanism 2 further includes: a limiting plate 201, a rotating column 202, a sliding seat 203, a pushing plate 204, a moving plate 205, a spring 206, a sliding column 207, a fixing box 208, and a torsion spring 209; there are three sliding seats 203, each of which is movably engaged in a sliding groove; the rotating column 202 is rotatably mounted on the top center of the sliding seat 203 via the torsion spring 209, and a limiting plate 201 is also sleeved on the outer wall of the rotating column 202, with both ends of the limiting plate 201 extending to the outer side of the sliding seat 203; the fixing box 208 is fixedly mounted on the sliding seat 203. A sliding column 207 is provided in 08. The outer end of the sliding column 207 abuts against the rotating column 202, and the inner end of the sliding column 207 abuts against the spring 206. The push plate 204 is rotatably connected in the inner cavity of the fixed box 208. Part of its position coincides with the moving stroke range of the sliding column 207. The bottom end of the push plate 204 is also rotatably connected to a horizontal moving plate 205. The other end of the moving plate 205 extends to the inner side of the telescopic moving mechanism 3. Multiple limiting plates 201 are of equal length, and the two ends of the limiting plates 201 are provided with connecting grooves in opposite positions. Multiple limiting plates 201 are connected by the connecting grooves at both ends. One of the limiting plates 201 corresponds to the telescopic end position of the cylinder 106.

[0049] Specifically, the locking mechanism 2 includes three parts, each corresponding to the legs and waist of the human body. All locking mechanisms 2 can move within the slide groove, providing the necessary displacement space for the human body during inversion. The limiting component includes a sliding seat 203, on which a rotating column 202 is mounted. The rotating column 202 is rotatably connected to the sliding seat 203 via a torsion spring. The outer wall of the rotating column 202 has protrusions. During use and in the process of inversion, all locking mechanisms 2 move from the front end of the slide groove to the limiting end. After moving to the limiting end, both ends of the limiting plates 201 on all slide grooves contact the fixed column 105 until complete contact is achieved. Each limiting plate on the limiting locking mechanism 2 is in a straight line. Multiple limiting plates 201 are fixed and attracted to each other by electromagnets. At the same time, they are attracted and fixed to one side of the fixing post 105 by electromagnets. At this time, the human body achieves the training effect of maintaining an inverted state through the setting of the locking mechanism 2. During the locking process, the human body can maintain the inverted posture relatively easily, allowing learners to experience the feeling of inversion. When it is necessary to release the locking state, the user can release the control of the electromagnet in the locking mechanism 2 through the control switch 107 next to the hand. The electromagnet loses its magnetic force, and the entire locking mechanism 2 and the telescopic moving mechanism 3 can move freely and gradually return to the standing posture.

[0050] It should be noted that when all the limiting plates 201 are attached to one end of the fixed column 105, the fixed column 105 forces all the limiting plates 201 to rotate. During this movement, since the limiting plates 201 and the rotating column 202 are rotatably set, and the outer wall of the rotating column 202 is also provided with a protrusion, after the protrusion rotates, it will push the sliding column 207 to produce displacement. Through the movement of the sliding column 207, the tilt angle of the push plate 204 is driven to change, and the moving plate 205 connected to the bottom end of the push plate 204 will also produce synchronous displacement. The moving plate 205 is used to release the limiting state of the telescopic moving mechanism 3.

[0051] Please see Figures 1 to 6 , Figure 12 , Figures 15 to 17As shown, in some examples, the telescopic moving mechanism 3 further includes: an upper sleeve 301, a middle sleeve 302, a lower sleeve 303, a limiting notch 304, and a sliding notch 311; the upper sleeve 301 is fixedly connected to the bottom end of the sliding seat 203, the upper sleeve 301 is hollow, and the middle sleeve 302 and the lower sleeve 303 are movably inserted into its inner side in stages, and a limiting component is provided on the inner wall of the contacting side of the upper sleeve 301, the middle sleeve 302, and the lower sleeve 303, wherein the top end of the limiting component is the driving end of the limiting component, and the driving end matches the position of the moving plate 205, and the bottom end of the lower sleeve 303 is rotatably connected to a fixing mechanism 4; the limiting notch 304 is opened at the middle position on both sides of the bottom end of the lower sleeve 303, and the sliding notch 311 is opened adjacent to the limiting notch 304.

[0052] It should be noted that the telescopic moving mechanism 3 corresponds to the locking mechanism 2 and is connected below the locking mechanism 2. It moves synchronously with the locking mechanism 2, which is set in the slide groove. The telescopic moving mechanism 3 includes an upper sleeve 301, a middle sleeve 302, and a lower sleeve 303, which are connected in stages. The bottom end of the lower sleeve 303 is connected to the human body through the fixing mechanism 4. The connection between the lower sleeve 303 and the fixing mechanism 4 is provided with a limit notch and a sliding notch 311 to limit the rotation angle of the fixing mechanism 4. This prevents the fixing mechanism 4 connected to the waist and legs from rotating during the user's inversion. When the action is in place, it can provide positioning support. In addition, it should be noted that a limit component is also provided in the inner wall of the lower sleeve 303 and the middle sleeve 302. The limit component ensures that after the multi-stage sleeve is retracted (due to the retraction of the multi-stage sleeve by the user's flipping), it can only move in one direction. This can also prevent the user from tipping over or being injured when the user's strength is insufficient or the force is not applied properly.

[0053] Please see Figures 10-14As shown, in some examples, the limiting assembly further includes mounting grooves on the inner walls of the middle sleeve 302 and the lower sleeve 303, and also includes: a sliding plate 305, a second spring 306, a connecting strip 307, a rotating inclined plate 308, a sliding block 309, and a third spring 310; the sliding plate 305 is horizontally movable and snapped into the bottom end of the inner wall of the middle sleeve 302 and the outer sleeve, one end of the sliding plate 305 is snapped into the mounting groove, and the other end of the sliding plate 305 is connected to the second spring 306; the connecting strip 307 is vertically movable. In the placement groove, the top of the connecting strip 307 is hollow, and a sliding block 309 and a spring 310 are provided on its inner side; several rotating inclined plates 308 are movably arranged in the placement groove, and one end of their inner side is rotatably connected to the two side walls of the connecting strip 307 through a strip groove. The outer end of the rotating inclined plate 308 is an inclined surface, and a pin shaft that is movably connected to the inner wall of the placement groove passes through the outer end of the rotating inclined plate 308. The outer bottom end of the sliding block 309 is engaged with the top of the placement groove, and all the sliding blocks 309 are corresponding to the position of the push plate 204.

[0054] In the specific implementation process, the limiting component includes a mounting groove opened on the lower sleeve 303 and the middle sleeve 302. A vertical connecting strip 307 is provided in the mounting groove. The mounting groove is also provided with multiple rotating inclined plates 308 that can be rotated by pins and are located on the outside of the connecting strip 307. One end of the inner side of all the rotating inclined plates 308 is movably connected to both sides of the connecting strip 307. A sliding block 309 and a spring 310 are also provided at the top of the connecting strip 307. When the sliding block 309 and the spring 310 are in the first state, most of the sliding block 309 is located on the outside of the connecting strip 307. The bottom end of the sliding block 309 abuts against the top of the mounting groove, preventing the connecting strip 307 from moving downward. When the sliding block 309 is stored in the connecting strip 307, it is in the second state. In the second state, the entire connecting strip 307 loses the limiting structure and moves downward under its own gravity.

[0055] Additionally, sliding plates 305, matching the positions of the mounting slots, are provided in the middle sleeve 302 and the upper sleeve 301. One end of the sliding plate 305 extends between the inclined surfaces of the two rotating inclined plates 308. As the user completes the inverted movement, the lower sleeve 303 and the middle sleeve 302 retract into the upper sleeve 301. The sliding plate 305 is fixedly installed in the inner wall of the bottom end of the middle sleeve 302 and the upper sleeve 301. During the retraction process, each rotating inclined plate 308 contacts the sliding plate 305 through its inclined surface, so that the overall telescopic moving mechanism 3 only has a retraction function and no extension effect. This can effectively prevent falls, back injuries, and other problems caused by insufficient force during the user's inverted movement. This continues until the lower sleeve 303 and the middle sleeve 302 are completely retracted into the upper sleeve 301. The sliding block 309 will correspond to the position of the moving plate 205, so that after the user completes the standard handstand, all locking mechanisms 2 move to the limiting end, and the position of the moving plate 205 changes. Through the displacement of the moving plate 205, all sliding blocks 309 are pushed to retract. When the sliding blocks 309 retract, the connecting bar 307 loses its displacement structure and moves downward under its own gravity. At the same time, the tilt angle of all rotating inclined plates 308 is changed. The inclined part of the rotating inclined plate 308 after the angle is rotated will detach from the sliding plate 305, so that the sliding plate 305 can move freely. At this time, the lower sleeve 303, the middle sleeve 302 and the upper sleeve 301 can move freely. When the user controls the action of the control button to release the electromagnet from the fixing effect, all the limiting effects are released, and the user can start to stand up.

[0056] Please see Figure 10 , Figure 12 As shown, in some examples, the fixing mechanism 4 further includes: a leg collar 401, a connecting block 402, a rotating support plate 403, and a telescopic block 410; the rotating support plate 403 is rotatably connected to the bottom end of the lower sleeve 303, and a connecting block 402 is also connected to the outside of the rotating support plate 403, and the leg collar 401 or waist collar 408 is connected to the outside of the connecting block 402; the telescopic block 410 is telescopically mounted on the outer wall of the rotating support plate 403 by another cylinder 106, and is located in the sliding notch 311 or the limiting notch 304.

[0057] It is understood that the fixing mechanism 4 is used to connect the telescopic moving mechanism 3 in this device to multiple parts of the human body, including the leg collar 401 and the waist collar 408. The leg collar 401 and the waist collar 408 are rotatably connected to the bottom end of the lower sleeve 303 through the rotating support plate 403. The rotating support plate 403 is provided with a telescopic block 410. The telescopic block 410 is controlled to extend and retract by another cylinder 106. The telescopic block 410 is slidably engaged in the sliding notch 311 and the limiting notch 304. In use, as the human body flips over, the telescopic block 410 will also rotate and engage in the limiting notch 304 to prevent the structure of the part in contact with the human body from moving after the user completes the inverted action, which would not provide effective support.

[0058] Please see Figure 5 , Figure 6 and Figures 15 to 17 As shown, in some examples, the fixing mechanism 4 further includes: a telescopic cylinder 404, a connecting ball 405, a spherical joint 406, and a track 407. The telescopic cylinder 404 is movably connected to the bottom side wall of the lower sleeve 303 through the spherical joint 406 and the connecting ball 405. The connecting ball 405 is also provided with a polygonal protrusion 409. The track 407 is opened on the inner wall of the spherical joint 406 and is movably sleeved on the outer side of the polygonal protrusion 409.

[0059] In this example, an alternative structure for the fixing mechanism 4 is provided. Unlike the previous example, the fixing mechanism 4 in this example also includes a telescopic cylinder 404. The telescopic cylinder 404 is connected to the bottom end of the lower sleeve 303 via a connecting ball 405 and a ball joint 406. The other end of the telescopic cylinder 404 is provided with a waist collar 408 and a leg collar 401 that connect to the human body. During the inversion process, the telescopic cylinder 404 further increases the user's leg range of motion, enabling multi-angle leg postures. In addition, to provide trainees with various leg movement postures, a polygonal protrusion 409 with a specific path and a recessed track 407 can be optionally provided in the movable joint of the connecting ball 405 and the ball joint. During the inversion process, the polygonal protrusion 409 is limited by the guide of the track 407, providing the user with a guiding and feedback effect, prompting the completion of advanced and difficult movements during the inversion process. The movement postures can be referenced. Figure 5 and Figure 6 Human body model 5.

[0060] A second aspect of this application provides a method for using a support and protection structure for practicing street dance moves, as described in the first aspect, comprising the following steps:

[0061] S10. The staff member stands on the base plate 101 and fixes his body with the leg loops 401 and waist loops 408, so that his body is connected to the telescopic moving mechanism 3 and the activity space of the telescopic moving mechanism 3 is confirmed.

[0062] S20. Lean forward to begin the inverted movement, move your legs up, and ensure that your hands support the ground. This will cause the fixing mechanism 4 to rotate. As your legs move up, the lower sleeve 303 and the middle sleeve 302 will retract. Through the limiting effect of the limiting component, only the lower sleeve 303 and the middle sleeve 302 can retract in one direction, preventing the user from falling over.

[0063] S30. After the inverted action is completed, the locking mechanism 2 will move to the limit end side to form a temporary inverted posture. At the same time, the current inverted angle is maintained by the electromagnet adsorption and fixation, so as to maintain the inverted posture relatively easily and overcome the fear of the inverted posture.

[0064] S40. After training is completed, the electric push rod is controlled by the control button to move the entire locking mechanism 2. The limiting plate 201 on the entire locking mechanism 2 returns to its initial angle. At the same time, the locking state of the limiting component and the fixing mechanism 4 is released, and the tilt angle of the body is changed to help the user return to an upright position. It plays an effective auxiliary and supportive training role in the process of correcting inversion and upright position.

[0065] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or electronic device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or electronic device. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or electronic device that includes that element.

[0066] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
