The physical training of teenagers can promote growth and development, the physical quality of the body of adults can be improved, the working efficiency is improved, and the physical training of the old people can cultivate sentiment and prolong the life.

Some leg training instruments in the prior art are perfect in functions and adjustable in load in fixed places such as gymnasiums or gymnasiums, but are large in size, heavy in appearance and high in cost, are not suitable for being purchased and used by trainers, are high in cost for long-term exercise in places such as gymnasiums or gymnasiums, and are inconvenient to go to the fixed places for each exercise; some leg training instruments are positioned in a park or a body-building square of a community, but the leg training instruments are often too simple in structural design due to the fact that the leg training instruments are suitable for being placed in an outdoor place for a long time, are small in load and cannot be adjusted, and only can play a role in slightly moving bodies or warming up, and cannot be used by trainers needing certain load.

For the above reasons, manufacturers have developed portable exercise devices that are mobile. Disclosed in chinese patent publication CN209348034U is a portable shank trainer, including U-shaped frame, slide subassembly, push pedal and seat subassembly, the both ends at the U-shaped frame back all articulate there is the bottom plate, and the both ends of bottom plate inboard all have welded the end pipe, the last fixed surface of bottom plate has first guide rail, and the last surface mounting of first guide rail has the bogie wheel, through first cross axle fixed connection between the bogie wheel, and connect through the fag end between first cross axle and the end pipe, the welding has the arc pipe between the end pipe, and installs the slide subassembly on the arc pipe, the outside of bottom plate all is fixed with the second guide rail, and sliding connection has the push pedal on the second guide rail, the last surface mounting of U-shaped frame has the seat subassembly. The technical effect that its expectation was reached is that the muscle training of convenient folding accomodating and carrying, multiple shank can be carried out, a tractor serves several purposes. However, the inventor believes that the device is detachable, but the size is still too large, a user needs to take a training posture of pushing the push plate with feet, the use skill is not easy to grasp, and the device is not safe enough under the condition of adopting a loading wheel; the training effect is improved by installing the loading wheels on the upper surface of the first guide rail, so that the weight of the whole device is greatly increased by the loading wheels, the seat assembly and the like, and the desire of being portable as much as possible is violated; in addition, the device adjusts the position of the seat component away from the push plate to adapt to users with different leg lengths, the adjustment is inconvenient, the adjustment of training load is not fully considered, and the device is not suitable for users with further requirements on training effect.

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings of the embodiments of the present disclosure.

It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

The use of the word "comprising" or "comprises", and the like, in this disclosure is intended to mean that the elements or items listed before that word, include the elements or items listed after that word, and their equivalents, without excluding other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

As shown in fig. 1 and 2, the portable leg training device provided in the embodiment of the present invention includes a support 1 and an elongated training device body 2, wherein the training device body 2 is mounted on the support 1 in an angle-adjustable manner, and includes a first damping mechanism 21 and a second damping mechanism 22 that are arranged in parallel, the first damping mechanism 21 and the second damping mechanism 22 are respectively provided with a first pedal 23 and a second pedal 24 for a trainer to step on with his/her left and right feet, in this embodiment, the width of the part of the first pedal 23 and the second pedal 24 that are respectively connected with the first damping mechanism 21 and the second damping mechanism 22 is larger than the width of the end thereof that is far away from the first damping mechanism 21 and the second damping mechanism 22, and the whole body is wedge-shaped. Such a structure allows the first and

second pedal bodies

231 and 241 of the first and

second pedals

23 and 24 to be trained by pedaling if the first and

second pedals

23 and 24 are kept in a horizontal position if the hinged position is on one side (upper position) and the other side (lower position) when they are hinged to the first and

second damping mechanisms

21 and 22 by the first and

second pins

234 and 244, respectively. When the pedal is not in use, the first pedal 23 and the second pedal 24 can be folded upwards around the first rotating shaft 234 and the second rotating shaft 244, so that the technical effects of volume reduction and portability are achieved. In the training device of the present invention, when the trainee steps on the first pedal 23 and/or the second pedal 24, the first damping mechanism 21 and the second damping mechanism 22 perform the first exercise stroke and the second exercise stroke substantially independently of each other. This corresponds to the similar training effect of stepping on the bicycle, that is, the left and right feet are alternately up and down, and certain damping is overcome to realize training. It can be seen that in this embodiment of the invention, the training device body 2 is actually connected to the support 1 in an angularly adjustable manner by means of a hinge seat 25, and in particular, the hinge seat 25 can be connected to the training device body 2 by means of a wing nut (not shown in fig. 2) cooperating with a rotating shaft. The purpose of this arrangement is similar to that of the first pedal 23 and the second pedal 24, and in the use state, the included angle between the training device body 2 and the support 1 can be adjusted to a proper size according to the training posture of the user, and then the butterfly nut is screwed. When the training is finished, the angle adjustment can be realized through the butterfly nut, so that the support 1 can be folded as close to the training device body 2 as possible, the storage space of the device can be further reduced, and the device is convenient to carry. Based on this design concept, in further modifications, as shown in fig. 1, the support 1 may preferably comprise a first portal 11 and a second portal 12, and have a first state angled to each other to form a support, and a second state nested to each other to facilitate folding. Further referring to fig. 1, the nested folding in the second state means that the first door-shaped bracket 11 and the second door-shaped bracket 12 are different in size, and fig. 1 shows that the second door-shaped bracket 11 is larger than the second door-shaped bracket 12, so that the second door-shaped bracket 12 can be overlapped with the first door-shaped bracket 11 by rotating the second door-shaped bracket 12, thereby achieving the nesting. And furthermore, the size of the device can be reduced to the maximum extent by adjusting the included angle between the support 1 and the training device body 2.

In the above solution, for the folding of the support 1, since the support 1 only needs to provide a relatively stable supporting function, and the first pedal 23 and the second pedal 24 are different, it not only needs to have sufficient support for the user's foot, but also belongs to the actuating unit, and during the whole training process, it needs to reciprocate in the training stroke (the first stroke and the second stroke). Therefore, considering that the first pedal 23 and the second pedal 24 may have friction with the first damping mechanism 21 and the second damping mechanism 22 under a stressed condition, in practical use, the first pedal 23 and the second pedal 24 are close to the first damping mechanism 21 and the second damping mechanism 22 side and close to the end of the support 1, and should be configured to be smooth arc-shaped curved surfaces to reduce friction. Meanwhile, it is also contemplated that the first and

second rollers

232 and 242, which are formed to be in rolling contact, may be provided at an end directly opposite to the first and

second rotation shafts

234 and 244, as shown in fig. 1. In addition, it is conceivable that the first roller 232 and the second roller 242 are preferably disposed oppositely and located at both sides of the first pedal body 231 and the second pedal body 241, respectively.

As for the first damping mechanism 21 and the second damping mechanism which mainly achieve the training effect in the present invention, specific structures of the first damping mechanism 21 and the second damping mechanism may be exemplarily shown in fig. 1 and fig. 2, specifically, the first damping mechanism 21 includes a first housing 211, a first sliding slot (not shown) is formed on an opposite outer side of the first housing 211, a first sliding cavity (not shown) is configured inside the first housing, a first sliding member (not labeled) which moves along a first movement stroke is disposed inside the first sliding cavity, a first energy storage assembly (not labeled) which charges or releases energy when the first sliding member moves is further disposed inside the first sliding cavity, and the first pedal passes through the first sliding slot and is connected with the first sliding member; likewise, the first damper mechanism 21 may be substantially identical in structure to the second damper mechanism 22, and the first and second housings 211 and 221 may be substantially integrally formed with the top closed by the end cap 26 to restrain the upward terminus of the first and second sliders. Fig. 1 and 2 show the structure of the second damping mechanism, which includes a second casing 221, a second sliding groove 222 is formed on the opposite outer side of the second casing 221, a second sliding cavity (not labeled) is configured inside the second casing, a second sliding member (not labeled) moving along a second movement stroke is arranged in the second sliding cavity, a second energy storage assembly (not labeled) charging or releasing energy when the second sliding member moves is further arranged in the second sliding cavity, and the second pedal 24 passes through the second sliding groove 222 and is connected with the second sliding member. In such a structure, as shown in fig. 2, the first slider and the second slider, in this particular embodiment, specifically include a first slide guide 233 and a compression spring 223, and a second slide guide 243 and a compression spring, respectively. The first step 23 is hinged on the first sliding guide 233 and the second step 24 is hinged on the second sliding guide. In this configuration, the compression spring constitutes a first energy storage assembly and a second energy storage assembly. In other embodiments, the first energy storage assembly and the second energy storage assembly may be embodied in another form, as shown in fig. 3 and 4, and in this preferred embodiment, the first energy storage assembly and the second energy storage assembly are configured as elastically deformable air bags 224. Compared with the scheme that the energy storage assembly is formed by the compression spring, the air bag 224 can provide the training force with nonlinear change, particularly, the front section of the stroke is softer, and the rear section of the stroke needs larger force, so that a user can exercise according to the physical condition of the user in fact, and self-adaptively trains different strokes and different forces. In the case of the airbag implementation, it is also conceivable that the first sliding chamber and the second sliding chamber communicate with each other on the side near the stroke end, and that the airbag constituting the first accumulator unit and the airbag constituting the second accumulator unit communicate with each other via a communication pipe 225. In this way, when two feet are trained alternately up and down, the compressed gas itself can communicate between the two air bags, which makes the actual foot feel experience completely different from that of the independent air bags. This is very similar to the user pressing down on the trampoline with both feet alternately, which is very suitable for children, women or old people with small leg strength, and is not easy to cause sports injury.

In addition, in consideration of adaptation to different user groups, it is more preferable that the damping strength of the first damping mechanism 21 and the second damping mechanism 22 in the present invention should be easily adjusted. Therefore, in the present invention, taking the scheme of the compression spring in the first embodiment as an example, an adjusting mechanism 3 for adjusting the stroke size of the first movement stroke and the second movement stroke respectively may be respectively disposed in the first sliding cavity and the second sliding cavity near the stroke ends, the adjusting mechanism 3 at least includes a stud 31 located in the first sliding cavity and the second sliding cavity and an adjusting nut 32 sleeved on the stud 31, and the compression spring 223 is sleeved on the stud 31. When adjustment is required, the adjustment nut 32 can be manually rotated through a correspondingly positioned cutout in the housing, and since the compression spring 223 abuts against the adjustment nut 32, the working height of the compression spring 223 can be in fact adjusted by the adjustment nut 32, thereby changing the damping force provided by the compression spring 223.

In addition, if the training result of the user needs to be recorded, evaluated or analyzed, it is also considered to provide the information sharing module 4 in the solution of the present invention. Specifically, as shown in fig. 2 and fig. 6, preferably, an information sharing module 4 is disposed in the first sliding cavity and/or the second sliding cavity near the end of the stroke, the information sharing module 4 at least includes an electric storage base 41 disposed on the hinge base 25, a piezoelectric sensing unit 42 disposed on the electric storage base 41 and electrically connected to the electric storage base 41, the first energy storage component and/or the second energy storage component abuts against the piezoelectric sensing unit (e.g., a piezoelectric ceramic plate) 42, and further includes a control board 43, and a communication unit 431 and a counter unit 432 connected to the control board 43; the counter unit 432 may actually be a programmable counter chip and is configured to obtain the number of training times for the first energy storage component and/or the second energy storage component to reach the formation end, and the control board is configured to transmit the number of training times through the communication unit (e.g., bluetooth). In this implementation, the power storage base 41 may specifically include a storage battery, and when the first power storage component moves downward, the pressure applied to the piezoelectric ceramic plate increases, so that the piezoelectric ceramic plate may generate electric energy, and the electric energy may be alternately stored in the storage battery for the control board 43 and the components disposed on the control board 43.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
