Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a lower limb training device. Background Art

The lower limb trainer in the prior art, such as the pedal machine, includes a base, a driving mechanism, a crank arm component, and a pair of pedals. One end of the pedal is connected to the base through a pulley, and the other end is connected to the output end of the driving mechanism through the crank arm component. The driving mechanism drives the pedal to slide and swing along the base through the crank arm component.

[0003] This type of lower limb trainer is only suitable for knee joint exercise training and cannot be used for exercise training of more parts such as calves, thighs, and soles of feet. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the lower limb training device in the prior art is only suitable for knee joint exercise training and cannot be used for exercise training of more parts such as calves, thighs, and soles of feet.

[0005] The solution adopted in this application is:

[0006] A lower limb trainer comprises: a base, a driving device, a pair of support platforms and a pair of pedals; the driving device comprises an electric drive installed on the base, and a pair of swing transmission mechanisms connecting the output parts on both sides of the electric drive; a pair of support platforms are separated from the output parts of the electric drive and correspond to the swing transmission mechanisms and are immovably constructed at a preset height position of the base; a pair of pedals, the ends of which are respectively connected to the corresponding support platforms so as to be movably connected around the corresponding axes, and are connected to the output ends of the corresponding swing transmission mechanisms so as to be movably connected around the corresponding axes at preset positions separated from the axes; the electric drive drives the pedals to swing relative to the support platforms through the swing transmission mechanism.

[0007] The lower limb trainer provided in the present application is constructed with a pair of fixed support platforms and a pair of pedals that swing asynchronously relative to the support platforms. The support surface of the support platform can be used to place the front of the user's foot, and the pedals can be used to support and drive the middle and rear parts of the user's foot. The asynchronous driving pedals of the driving device, such as asynchronous swinging, can enable the user's calves, thighs and feet to receive active training at the same time, realizing multi-part linkage training, good training effect, excellent user experience and simple structure.

[0008] Furthermore, a connecting seat is constructed on the side of the support platform where it connects to the pedal. The connecting seat is configured to be lower than the support surface of the support platform. One end of the pedal is connected to the connecting seat via a pin. When the pedal is in the lowest position, the surface of the pedal aligns with the surface of the support platform. This improvement simplifies the connection structure and ensures that the surface of the pedal aligns with the surface of the support platform when in the lowest position, avoiding a large gradient that affects the user experience.

[0009] Furthermore, a pin connection portion is provided at one end of the pedal, and the connection seat is configured with one or more pin mounting holes, and the pin passes through the pin connection portion and is connected to the corresponding connection seat by screws. With the above improvement, the fixing structure of the pin is simple and economical.

[0010] Furthermore, a blocking coupling portion is constructed on the upper side of one end of the pedal to block at least the upper side of the pin. The pin mounting hole communicates with the lower side of the connecting seat, allowing a screw to connect to the pin from the lower side of the pin mounting hole. This improvement improves safety by preventing exposure to the pedal during swinging, which could pose a safety hazard, while also enhancing the pedal's aesthetics. Furthermore, the screw is installed from the lower side of the pin mounting hole, ensuring the integrity of the blocking coupling portion.

[0011] Furthermore, the support platform has a first curved coupling surface on the side adjacent to the pedal, and the blocking coupling portion has a second curved coupling surface that couples with the first coupling surface. When the pedal swings relative to the support platform, the second coupling surface swings in close proximity to the first coupling surface. This improvement, combined with the curved first and second coupling surfaces, keeps the clearance between the pedal and the support platform consistently small, further enhancing safety.

[0012] Specifically, a first arc-shaped coupling surface is constructed on one side of the support platform adjacent to the connecting seat.

[0013] Furthermore, the edge of the support platform is constructed with an integrally shaped retaining wall, and one end of the pedal is connected to one side of the opening of the retaining wall. The retaining wall can locate the position of the user's foot, thereby improving the convenience and safety of use.

[0014] Furthermore, the support platform and the base are manufactured separately and then assembled and connected. The above solution is convenient to manufacture and has good economic efficiency.

[0015] Furthermore, a drive mount is constructed in the middle of the base. The electric drive includes a motor and a reduction mechanism. The output components of the electric drive are constructed on either side of the reduction mechanism. The motor and the output components of the electric drive are arranged perpendicularly on one side near the support platform. This layout fully utilizes the space between the drive mount and the support platform, making the product more compact.

[0016] Furthermore, the drive mounting base includes opposing supports, with a first drive mounting portion configured on the upper side of the supports. The reduction mechanism includes a reduction gear, a gear shaft coupled to the motor output shaft, and a reduction housing. An output shaft is mounted in the middle of the reduction gear, with both ends of the output shaft extending out of the reduction housing to form the output portion of the electric drive. Second drive mounting portions are configured on both sides of the reduction housing, and the reduction mechanism is connected to the first drive mounting portion via the second drive mounting portion. The above solution results in a small reduction mechanism, good installation stability, and a compact overall structure. BRIEF DESCRIPTION OF THE DRAWINGS

This installation scheme prevents the obstruction of coupling portion 4.11 from interfering with the installation of pin 4.3, thereby reducing the gap between the first and second pedals 4.1, 4.2 and the first and second support platforms 3.1, 3.2.

[0050] like Figure 11 As shown, the first platform support 3.1' and the second platform support 3.2' can be connected to the base 1 through the connection holes 3.13, such as screw connections.
