DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] In this document, reference to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. Those skilled in the art will understand that the embodiments described herein can be combined with one another.

[0034] Please refer to Figure 1The application provides a Haake machine 100, comprising a base frame 10, a load backrest 20 and a foot pedal assembly 30. The base frame 10 has a guide slide rail 121, and the load backrest 20 is slidably arranged on the guide slide rail 121. The foot pedal assembly 30 comprises a first pedal 31 and a second pedal 32 arranged side by side, one end of the first pedal 31 is rotatably arranged on the base frame 10 to adjust the included angle between the first pedal 31 and the load backrest 20, and one end of the second pedal 32 is rotatably arranged on the base frame 10 to adjust the included angle between the second pedal 32 and the load backrest 20.

[0035] It can be seen that the Haake machine 100 provided by the application is provided with two independent pedals, and the included angle between each pedal and the load backrest 20 can be adjusted independently. When a user uses the Haake machine 100, two feet can be respectively stepped on the first pedal 31 and the second pedal 32, and when the included angles between the two pedals and the load backrest 20 are different, the support forces of the two legs of the user are also different, so that the effect of purposefully training one leg can be achieved, and the flexibility of the Haake machine 100 training is improved. In addition, by adjusting the angles between the two pedals and the load backrest 20, the Haake machine 100 can also adapt to users of different heights and body proportions.

[0036] The base frame 10 is used to load the load backrest 20 and the foot pedal assembly 30. The specific shape and structure of the base frame 10 are not limited in the embodiments of the application. For example, as shown in Figure 1 the base frame 10 can be formed by splicing profiles, and the base frame 10 can comprise a base 11 and a support frame 12. Taking the placement state of the Haake machine 100 in normal use as an example, the base 11 is horizontally placed on the ground, and the support frame 12 is arranged on the base 11 at a certain inclined angle and is used to load the load backrest 20. The support frame 12 is provided with the guide slide rail 121, which can be arranged in parallel with the support frame 12, and the guide slide rail 121 can be a cylindrical guide rod structure, but is not limited thereto. For example, the guide slide rail 121 can also be a track with a cross-sectional shape of an I-shaped section or a trapezoidal section, or a sliding groove arranged on the support frame 12. In order to ensure the stability of the load backrest 20 sliding along the guide slide rail 121, the guide slide rail 121 can be provided with two, which are distributed on the opposite sides of the load backrest 20.

[0037] The load backrest 20 is slidably arranged on the guide slide rail 121. It can be understood that the load backrest 20 is provided with a guide sliding block 21 matched with the guide slide rail 121, and taking the example that the guide slide rail 121 is a cylindrical guide rod structure and the guide slide rail 121 is provided with two distributed on the opposite sides of the load backrest 20, the corresponding guide sliding block 21 is a cylindrical sleeve structure. As shown in Figure 1As shown, in some embodiments, the load backrest 20 can further include a mounting plate 22, a backrest plate 23 and a load part 24, two guide sliding blocks 21 matched with the two guide sliding rails 121 are distributed on opposite sides of the mounting plate 22, the backrest plate 23 and the load part 24 are arranged on the mounting plate 22, and the load part 24 is distributed on opposite sides of the backrest plate 23, so that the load part 24 can correspond to the shoulders of the user when the user leans on the backrest plate 23. However, the structure of the load backrest 20 is not limited thereto. In addition, it should be noted that, since the load backrest 20 is generally arranged in parallel with the guide sliding rails 121, the included angle between the first pedal 31 and the load backrest 20 and the included angle between the second pedal 32 and the load backrest 20 can be understood as the included angle between the first pedal 31 and the second pedal 32 and the guide sliding rails 121.

[0038] The foot pedal assembly 30 is arranged on the base 11 of the base frame 10 and is used to support the feet of the user during training. The foot pedal assembly 30 includes the first pedal 31 and the second pedal 32 arranged side by side, and the first pedal 31 and the second pedal 32 are used to support the feet of the user respectively. One end of each of the first pedal 31 and the second pedal 32 is rotatably arranged on the base frame 10. It can be understood that one end of each of the first pedal 31 and the second pedal 32 towards the load backrest 20 is rotatably arranged on the base frame 10, and the rotation axes of the first pedal 31 and the second pedal 32 are in the same direction. The specific rotatable arrangement of the first pedal 31 and the second pedal 32 on the base frame 10 is not limited in the embodiments of the present application, for example, the first pedal 31 and the second pedal 32 are directly rotatably arranged on the base frame 10 through a rotating shaft, but are not limited thereto.

[0039] In some embodiments, the side-by-side interval of the first pedal 31 and the second pedal 32 can be 10-30 mm in the direction of the rotation axes of the first pedal 31 and the second pedal 32. For example, the side-by-side interval of the first pedal 31 and the second pedal 32 can be 10 mm, 15 mm, 20 mm, 25 mm or 30 mm, but is not limited thereto. For example, in some embodiments, the side-by-side interval of the first pedal 31 and the second pedal 32 is 20 mm, that is, the independent rotatable arrangement of the first pedal 31 and the second pedal 32 on the base frame 10 is not affected, and the distance between the first pedal 31 and the second pedal 32 is also not too large to affect the user training.

[0040] As shown, in some embodiments, the load backrest 20 can further include a mounting plate 22, a backrest plate 23 and a load part 24, two guide sliding blocks 21 matched with the two guide sliding rails 121 are distributed on opposite sides of the mounting plate 22, the backrest plate 23 and the load part 24 are arranged on the mounting plate 22, and the load part 24 is distributed on opposite sides of the backrest plate 23, so that the load part 24 can correspond to the shoulders of the user when the user leans on the backrest plate 23. However, the structure of the load backrest 20 is not limited thereto. In addition, it should be noted that, since the load backrest 20 is generally arranged in parallel with the guide sliding rails 121, the included angle between the first pedal 31 and the load backrest 20 and the included angle between the second pedal 32 and the load backrest 20 can be understood as the included angle between the first pedal 31 and the second pedal 32 and the guide sliding rails 121. Figure 1As shown, in some embodiments, the Hark machine 100 can further comprise a support assembly. The support assembly comprises a first support rod 33 and a second support rod 34. The first support rod 33 is arranged on the side of the first pedal 31 away from the load backrest 20 for supporting the first pedal 31; the second support rod 34 is arranged on the side of the second pedal 32 away from the load backrest 20 for supporting the second pedal 32. By arranging the first support rod 33 and the second support rod 34 on the side of the first pedal 31 and the second pedal 32 away from the load backrest 20 respectively, the pedals can be stably supported by the support rods, and the angles of the pedals can be adjusted by adjusting the length of the support rods or the support position of the support rods.

[0041] For example, as Figure 1 As shown, in some embodiments, the first pedal 31 is provided with a plurality of first adjusting grooves 311 on the side away from the load backrest 20, the first adjusting grooves 311 are arranged along the direction perpendicular to the rotation axis of the first pedal 31, one end of the first support rod 33 is rotatably arranged on the base frame 10, and the other end is matched with the first adjusting grooves 311. Correspondingly, the second pedal 32 is provided with a plurality of second adjusting grooves 321 on the side away from the load backrest 20, the second adjusting grooves 321 are arranged along the direction perpendicular to the rotation axis of the second pedal 32, one end of the second support rod 34 is rotatably arranged on the base frame 10, and the other end is matched with the second adjusting grooves 321. By matching the first support rod 33 with different first adjusting grooves 311 and the second support rod 34 with different second adjusting grooves 321, the angles of the first pedal 31 and the second pedal 32 can be adjusted respectively, and the user can directly adjust the angles of the first pedal 31 and the second pedal 32 according to his own situation, which is convenient and fast.

[0042] The specific shape structure of the first adjusting grooves 311 and the second adjusting grooves 321 is not limited, and in this embodiment, the shape structure of the first adjusting grooves 311 and the first support rod 33 is taken as an example for description. As Figure 1As shown, the side of the first pedal 31 away from the load backrest 20 is provided with an extension plate, and a plurality of first adjusting grooves 311 are formed on the extension plate. The end of the first support rod 33 matched with the first adjusting grooves 311 is provided with a support shaft matched with the first adjusting grooves 311, for example, the support shaft is arranged through the first support rod 33, and the two end portions of the support shaft extending out of the first support rod 33 are both provided with limiters, so that after the support shaft is matched with the first adjusting grooves 311 in the direction of the central axis of the support shaft, the extension plate is located between the first support rod 33 and the limiters, thereby ensuring the stability of the matching of the first support rod 33 and the first adjusting grooves 311. In order to facilitate the first support rod 33 to be adjusted from one of the plurality of first adjusting grooves 311 to another first adjusting groove 311, one end of the plurality of first adjusting grooves 311 can be connected through a communication groove. The shape structure of the second adjusting groove 321 can be the same as that of the first adjusting groove 311, and correspondingly, the shape structure of the second support rod 34 is also the same as that of the first support rod 33. The shape of the second adjusting groove 321 and the second support rod 34 will not be described here.

[0043] In some embodiments, the first support rod 33 and the second support rod 34 can also be telescopic rods, one end of the first support rod 33 is rotatably connected to the first pedal 31, and the other end is rotatably connected to the base frame 10; the first end of the second support rod 34 is rotatably connected to the second pedal 32, and the other end is rotatably connected to the base frame 10. The telescopic adjustment of the first support rod 33 and the second support rod 34 can be used to respectively adjust the angles of the first pedal 31 and the second pedal 32. The rotatable arrangement of the two ends of the first support rod 33 and the second support rod 34 in the embodiment is not limited, for example, the support rod is provided with a rotating shaft, and the corresponding pedal and the base frame 10 are provided with a connecting seat matched with the rotating shaft.

[0044] Regarding the telescopic adjustment mode of the first support rod 33 and the second support rod 34, for example, Figure 2 and Figure 3As shown in some embodiments, the first support rod 33 and the second support rod 34 can each include a first rod member 351 and a second rod member 352, and the first rod member 351 and the second rod member 352 are arranged to be relatively slidable along the axial direction thereof. The first rod member 351 can be provided with a spring pin 353, and the second rod member 352 is provided with a plurality of positioning holes 354 arranged along the axial direction thereof, and the positioning holes 354 are used to cooperate with the spring pin 353 to realize the extension and retraction of the first support rod 33 and the second support rod 34. In the embodiment, the first rod member 351 and the second rod member 352 are arranged to be relatively slidable, for example, the second rod member 352 can be a tubular structure, and the second rod member 352 is sleeved on the outer periphery of the first rod member 351. When it is necessary to adjust the angle of the first pedal 31 and the second pedal 32, the spring pin 353 is pressed and the first rod member 351 and the second rod member 352 are relatively slid, and after being adjusted to the appropriate position, the spring pin 353 is released to cooperate with the positioning hole 354 at the corresponding position, so as to complete the adjustment. The adjustment operation is simple and fast.

[0045] As shown in some embodiments, the first support rod 33 and the second support rod 34 can each include a first rod member 351 and a second rod member 352, and the first rod member 351 and the second rod member 352 are arranged to be relatively slidable along the axial direction thereof. The first rod member 351 can be provided with a spring pin 353, and the second rod member 352 is provided with a plurality of positioning holes 354 arranged along the axial direction thereof, and the positioning holes 354 are used to cooperate with the spring pin 353 to realize the extension and retraction of the first support rod 33 and the second support rod 34. In the embodiment, the first rod member 351 and the second rod member 352 are arranged to be relatively slidable, for example, the second rod member 352 can be a tubular structure, and the second rod member 352 is sleeved on the outer periphery of the first rod member 351. When it is necessary to adjust the angle of the first pedal 31 and the second pedal 32, the spring pin 353 is pressed and the first rod member 351 and the second rod member 352 are relatively slid, and after being adjusted to the appropriate position, the spring pin 353 is released to cooperate with the positioning hole 354 at the corresponding position, so as to complete the adjustment. The adjustment operation is simple and fast. Figure 4 Figure 5 As shown in some embodiments, the first support rod 33 and the second support rod 34 can each include a first rod member 351 and a second rod member 352, and the first rod member 351 and the second rod member 352 are arranged to be relatively slidable along the axial direction thereof. The first rod member 351 can be provided with a spring pin 353, and the second rod member 352 is provided with a plurality of positioning holes 354 arranged along the axial direction thereof, and the positioning holes 354 are used to cooperate with the spring pin 353 to realize the extension and retraction of the first support rod 33 and the second support rod 34. In the embodiment, the first rod member 351 and the second rod member 352 are arranged to be relatively slidable, for example, the second rod member 352 can be a tubular structure, and the second rod member 352 is sleeved on the outer periphery of the first rod member 351. When it is necessary to adjust the angle of the first pedal 31 and the second pedal 32, the spring pin 353 is pressed and the first rod member 351 and the second rod member 352 are relatively slid, and after being adjusted to the appropriate position, the spring pin 353 is released to cooperate with the positioning hole 354 at the corresponding position, so as to complete the adjustment. The adjustment operation is simple and fast.

[0046] As shown in some embodiments, the first support rod 33 and the second support rod 34 can each include a first rod member 351 and a second rod member 352, and the first rod member 351 and the second rod member 352 are arranged to be relatively slidable along the axial direction thereof. The first rod member 351 can be provided with a spring pin 353, and the second rod member 352 is provided with a plurality of positioning holes 354 arranged along the axial direction thereof, and the positioning holes 354 are used to cooperate with the spring pin 353 to realize the extension and retraction of the first support rod 33 and the second support rod 34. In the embodiment, the first rod member 351 and the second rod member 352 are arranged to be relatively slidable, for example, the second rod member 352 can be a tubular structure, and the second rod member 352 is sleeved on the outer periphery of the first rod member 351. When it is necessary to adjust the angle of the first pedal 31 and the second pedal 32, the spring pin 353 is pressed and the first rod member 351 and the second rod member 352 are relatively slid, and after being adjusted to the appropriate position, the spring pin 353 is released to cooperate with the positioning hole 354 at the corresponding position, so as to complete the adjustment. The adjustment operation is simple and fast. Figure 5 ​As shown, in some embodiments, the threaded sleeve 362 in the first support rod 33 and the second support rod 34 is rotatable about its axial direction. The outer periphery of the threaded sleeve 362 may also be provided with a mounting portion 363 and a driven gear 364. The mounting portion 363 is equipped with a drive motor 366 and a driving gear 365. The driving gear 365 is connected to the output end of the drive motor 366 and meshes with the driven gear 364. Thus, the first support rod 33 and the second support rod 34 can be automatically extended and retracted by the motor. In some embodiments, to facilitate user adjustment of the first pedal 31 and the second pedal 32, the control buttons on the first support rod 33 and the second support rod 34 corresponding to the drive motor 366 are accessible when the user steps on the foot pedal assembly 30. When the user wants to adjust the angle of the first pedal 31 and / or the second pedal 32 during training, they do not need to get off the machine 100 to adjust it, making adjustment convenient and improving the user experience.

[0047] like Figure 6 As shown, in some embodiments, a first slide rail 111 and a second slide rail 112 may also be formed on the base frame 10. The first slide rail 111 and the second slide rail 112 extend along a direction perpendicular to the rotation axis of the first pedal 31 and the second pedal 32, and a first slider 113 is slidably disposed on the first slide rail 111, and a second slider 114 is slidably disposed on the second slide rail 112. A first support rod 33 is rotatably connected to one end of the base frame 10 and is rotatably connected to the first slider 113, and a second support rod 34 is rotatably connected to one end of the base frame 10 and is rotatably connected to the second slider 114. In this embodiment, the specific structures of the first slide rail 111, the second slide rail 112, and the corresponding first slider 113 and second slider 114 are not limited. For example, the first slide rail 111 and the second slide rail 112 can be grooves, and the first slider 113 and the second slider 114 can be embedded in the grooves. Alternatively, the first slide rail 111 and the second slide rail 112 can be track structures with an I-shaped or trapezoidal cross-sectional shape, and the first slider 113 and the second slider 114 can be provided with mating grooves corresponding to the cross-sectional shape of the track. In this way, without changing the length of the first support rod 33 and the second support rod 34, the angle of the first pedal 31 and the second pedal 32 can also be adjusted by adjusting the position of the first slider 113 and the second slider 114 on their corresponding slide rails, increasing the flexibility of pedal adjustment.

[0048] like Figure 6As shown, in some embodiments, the base frame 10 can also be provided with a driving screw rod 115. The driving screw rod 115 is located between the first sliding rail 111 and the second sliding rail 112, and the driving screw rod 115 is provided with a threaded sleeve 116, so that the first sliding block 113 and the second sliding block 114 are connected with the threaded sleeve 116. In this way, by rotating the driving screw rod 115, the positions of the first sliding block 113 and the second sliding block 114 on the corresponding sliding rails can be adjusted synchronously, that is, the angles of the first pedal 31 and the second pedal 32 can be adjusted synchronously.
