BRIEF DESCRIPTION OF THE DRAWINGS
[0024] The present disclosure is further described in detail below based on the accompanying drawings and embodiments.
[0025] Figure 1 A schematic diagram of a partially assembled strength training machine according to an embodiment of the present disclosure. DETAILED DESCRIPTION
[0026] In order to make the technical problems solved by the present disclosure, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0027] Existing strength training machines generally include an upper cover plate and a lower base plate, as well as a frame disposed between the upper cover plate and the lower base plate, and the frame is generally used to ensure the rigidity or stability of the entire machine. On the one hand, the frame is used to install tension components and guide components, etc. On the other hand, the frame is used to support the upper cover plate. Since the strength training machine needs to be designed to reduce weight, the frame is generally configured in a frame shape, and the upper cover plate is also designed to be relatively thin, which has the problem of insufficient rigidity. Therefore, the upper cover plate is supported by a frame-shaped frame, which inevitably leads to a small contact surface between the upper cover plate and the frame, which in turn leads to the user's feeling that the foot pedal is not strong enough or not strong enough during training, resulting in poor user experience and poor training effect. Technical problems.
[0028] In order to solve the above technical problems, the utility model breaks the conventional idea of setting a thinner upper cover plate, and adopts a rigid cover plate 20 to replace the frame and the thinner upper cover plate. On the one hand, it ensures that the upper cover plate is not easily deformed during user training. At the same time, the rigid cover plate 20 also serves as an installation base plate, and most of the weight of the strength training machine is concentrated on the rigid cover plate 20, which greatly improves the rigidity of the whole machine as a whole and ensures the stability of the whole machine during training.
[0029] like Figure 1 As shown, an embodiment of the utility model provides a strength training machine, which includes an upper cover plate, a lower base plate 10, an electric control board 50, a tension assembly, a guide assembly 60 and a support assembly 40. The upper cover plate and the lower base plate 10 are assembled to form a cavity for installing the electric control board 50, the tension assembly, the guide assembly 60 and the support assembly 40. The upper cover plate and the lower base plate 10 can be assembled by threaded connection or snap-on connection, and the specific assembly structure and assembly method are not specifically limited.
[0030] The upper cover plate is a rigid cover plate 20, and the rigid cover plate 20 includes a first side and a second side opposite to the first side. The rigid cover plate 20 is used to ensure the rigidity and strength of the whole machine. The first side of the rigid cover plate 20 is used to realize the centralized installation of multiple components, thereby ensuring that most of the weight of the whole machine is concentrated on the rigid cover plate 20, and the second side of the rigid cover plate 20 is used to provide a footrest area for the user or trainer. It should be noted that the rigid cover plate 20 specifically refers to a cover plate with sufficient strength to meet the requirements that after the installation of each component, it can withstand the weight of the components without deformation, or only a small deformation occurs. Further explanation in combination with the use scenario of the strength training machine: When the user uses the strength training machine, the user generally steps on the second side of the rigid cover plate 20 with his feet, and during the training process, the user's posture will change, which will cause the user's center of gravity to move or the pressure applied to the upper cover plate by the footrest area to change or fluctuate. Thus, in the present invention, in order to overcome the defects in the prior art, the setting of the frame is cancelled, and the upper cover plate is directly set as a rigid cover plate 20, so that the rigidity of the rigid cover plate 20 is sufficient to meet the training scenario, and the rigid cover plate 20 will hardly deform, which is sufficient to ensure the user's training effect and enhance the user's training experience.
[0031] Specifically, the first side of the rigid cover plate 20 is installed with a tension assembly, a guide assembly 60, an electric control panel 50 and a support assembly 40. The tension assembly includes a resistance adjustment unit 31, a winding wheel 32 and a pull rope 33. The resistance adjustment unit 31 and the winding wheel 32 are both installed on the first side of the rigid cover plate 20; one end of the pull rope 33 is fixedly connected to the outer periphery of the winding wheel 32, and the other end of the pull rope 33 is guided by the guide assembly 60 and passes through the rope outlet hole. The other end of the pull rope 33 is used to connect the training assembly, which can be a handle or a pull rod. The resistance adjustment unit 31 is used to drive the winding wheel 32 to recycle or release the pull rope 33, and the resistance adjustment unit 31 provides resistance to meet the user's exercise needs.
[0032] The rigid cover plate 20 is provided with a rope outlet hole penetrating the first side and the second side, and the guide assembly 60 is used to guide the pull rope 33 so that the pull rope 33 can be smoothly extended or retracted through the rope outlet hole. The guide assembly 60 is installed at the rope outlet hole to guide the pull rope 33.
[0033] The support assembly 40 is mounted on the first side of the rigid cover plate 20, and is used to support the strength training machine on the training ground. In this embodiment, the support assembly 40 includes a first end and a second end opposite thereto, the second end of the support assembly 40 is arranged toward the lower base plate 10, a through hole 11 is arranged on the lower base plate 10, the second end of the support assembly 40 at least partially passes through the through hole 11, and the second end of the support assembly 40 contacts the training ground to achieve the support placement of the whole machine. In this embodiment, the number of the support assemblies 40 is set to 4, and the 4 support assemblies 40 are evenly distributed on the first side of the rigid cover plate 20, and all partially pass through the through hole 11 on the lower base plate 10. The lower base plate 10 basically has no installed parts, and there is no need to consider the design of rigidity and strength. Therefore, the lower base plate 10 only needs to meet the requirements of the decorative plate, which greatly reduces the manufacturing process and performance requirements for the lower base plate 10, and also greatly reduces the design and manufacturing cost of the lower base plate 10.
[0034] The support assembly 40 can be integrally formed with the rigid cover plate 20, or can be detachably assembled and connected with the rigid cover plate 20. The specific connection method between the support assembly 40 and the rigid cover plate 20 is not limited in this utility model.
[0035] By setting the upper cover plate as a rigid cover plate 20, this embodiment can reduce the number of frames, so that the strength training machine can be designed to be lighter, thinner and more compact. At the same time, since the upper cover plate is a rigid cover plate 20, the footrest area is rigid enough, and the user's footrest is strong enough and not easily deformed during training, so the user experience is good and the training effect is good. On the other hand, the rigid cover plate 20 is used for multiple purposes, and the tension component and the guide component 60 are both installed on the first side of the rigid cover plate 20, so that most of the weight of the whole machine is concentrated on the rigid cover plate 20, which greatly improves the rigidity of the whole machine as a whole and ensures the stability of the whole machine during training.
[0036] At the same time, the installation body of the support component 40 is the rigid cover plate 20. The support component 40 directly supports the entire weight on the rigid cover plate 20, so that most of the weight of the whole machine can be effectively supported and rarely deformed, thereby ensuring the stability of the whole machine during training.
[0037] Continue to refer Figure 1As an optional embodiment, the number of the tension assembly and the rope outlet hole are both two, the two rope outlet holes are arranged along the length direction of the rigid cover plate 20, the two rope outlet holes are symmetrically arranged at the two ends of the rigid cover plate 20, the tension assembly is arranged at the end away from the rigid cover plate 20 compared to the rope outlet holes, and the electric control board 50 is arranged between the two tension assemblies. The electric control board 50 is located at the center of the entire strength training machine, the tension assembly is arranged close to the electric control board 50 and is respectively located on both sides of the electric control board 50, and the pull rope 33 in the tension assembly passes through the rope outlet hole. The entire layout is compact, the space utilization rate is high, and it is convenient to route the wires to the two ends of the strength training machine with the control board as the center. The rope outlet hole is arranged closer to the end of the rigid cover plate 20 than the electric control board 50 and the tension assembly, which is conducive to fully utilizing the space of the cavity formed by the upper cover plate and the lower base plate 10, and is convenient for realizing the centralized installation of the tension assembly and the electric control board 50.
[0038] It should be noted that, in this embodiment, the length direction of the rigid cover plate 20 is the direction of the line connecting the two rope outlet holes. In this embodiment, the rigid cover plate 20 is a rectangular parallelepiped, and the rope outlet holes are arranged along the length direction of the rectangular parallelepiped.
[0039] refer to Figure 1 In some embodiments, a cooling fan (not shown in the figure) is provided on the electric control board 50, and the cooling fan discharges air along the width direction of the rigid cover plate 20. Two cooling holes 12 are provided on the lower base plate 10, and the cooling holes 12 are arranged opposite to the tension assembly, and the cooling fan and the cooling holes 12 are arranged staggered. The cooling fan is installed on the electric control board 50 located in the middle of the strength training machine to achieve heat dissipation of the electric control board 50; at the same time, the cooling fan is arranged to blow air in the width direction of the rigid cover plate 20, and the cooling holes 12 are not directly arranged on the direct blowing path of the cooling fan, which enables the airflow to be well diffused in the cavity surrounded by the upper cover plate and the lower base plate 10, and the airflow can contact the rigid cover plate 20 with a large area with heat, and the entire rigid cover plate 20 acts as a heat sink, which greatly improves the heat dissipation efficiency.
[0040] At the same time, since the tension component has a large heat dissipation, on the one hand, since the tension component is directly mounted on the rigid cover plate 20, part of the heat it dissipates can be dissipated through the rigid cover plate 20 acting as a heat sink, and on the other hand, the heat dissipation holes 12 are arranged to correspond to the installation position of the tension component. The heat dissipation holes 12 are arranged here to facilitate part of the heat dissipated by the tension component to quickly flow out through the heat dissipation holes 12 on the lower base plate 10, thereby greatly reducing the time that the heat stays in the cavity.
[0041] In this embodiment, the entire heat dissipation method, by setting the heat dissipation fan to be staggered with the heat dissipation hole 12, makes the airflow in the cavity well evenly distributed, and then can fully utilize the good thermal conductivity of the rigid cover plate 20 itself for heat dissipation. At the same time, the heat dissipation hole 12 is just set at a position relative to the tension component, so that the heat dissipation hole 12 and the tension component are very close, and the tension component generates relatively more heat. The heat dissipation hole 12, as an air outlet, can directly and quickly take part of the heat of the tension component out of the cavity at the first time, greatly improving the heat dissipation efficiency. It should be noted that, different from the heat dissipation hole 12 set on the side wall, the heat dissipation hole 12 in this embodiment is horizontally set on the lower base plate 10, and the blowing direction of the heat dissipation fan is along the width direction of the rigid cover plate 20, so that the blowing direction and the air outlet direction are at an angle of 90° (direct convection cannot be formed), which is more conducive to achieving the divergence of the airflow in the cavity, and then fully utilizing the thermal conductivity of the rigid cover plate 20 itself.
[0042] It should be noted that, since the tension assembly includes the resistance adjustment unit 31, which is the main heat generating unit, the heat dissipation holes 12 can be preferably arranged to be opposite to the resistance adjustment unit 31. However, in other embodiments, the heat dissipation holes 12 can also be arranged symmetrically about the left and right ends of the strength training machine, ensuring that the heat dissipation holes 12 are arranged opposite to the tension assembly as a whole.
[0043] Regarding the air outlet of the cooling fan along the width direction of the rigid cover plate 20 , it can be understood that the air outlet direction of the cooling fan is perpendicular to the length direction of the rigid cover plate 20 , that is, perpendicular to the arrangement direction of the two tension components.
[0044] Continue to refer Figure 1As an optional embodiment, the resistance adjustment unit 31 is a disc motor, and the winding wheel 32 is connected to the disc motor with a belt drive. The winding wheel 32 has a rope outlet, and the pull rope 33 is pulled out or wound through the rope outlet. The rope outlet direction of the rope outlet is set to point to the corresponding rope outlet holes respectively. The two groups of tension components are arranged in opposite directions along the width direction of the rigid cover plate 20, so that the motors or winding wheels 32 in the two groups of tension components are arranged diagonally. The use of a disc motor and a belt drive connection method is conducive to reducing the overall size of the tension component in the thickness direction, thereby facilitating the compact design of the strength training machine as a whole. At the same time, in order to facilitate the synchronous rotation control of the motors on the left and right sides, the motors and winding wheels 32 in the two groups of tension components are arranged in opposite directions; and the opposite setting of the two winding wheels 32 can ensure that the winding direction of the pull rope 33 remains consistent, and there is no need to distinguish between the two winding wheels 32 during assembly, and the assembly is efficient. At the same time, since the weight of the motor is generally much greater than the weight of the winding wheel 32, the motors of the two sets of tension components are set in opposite directions, so that the weight distribution of the strength training machine is relatively uniform, which effectively avoids the lateral deviation of the center of gravity of the strength training machine, ensures the stability of the strength training machine placed on the training ground, and reduces the possibility of rollover due to excessive force.
[0045] As an optional embodiment, the rope outlet direction of the rope outlet forms an angle of 35°-55° with the length direction of the rigid cover 20. In this way, when the user uses the device for training, the winding and releasing of the pull rope 33 on the winding wheel 32 can achieve an optimal level of smoothness, which increases the smoothness of the device to a certain extent.
[0046] As an optional embodiment, the rope outlet directions of the two winding wheels 32 are parallel to the plane where the rigid cover plate 20 is located, ensuring that the pull rope 33 can be smoothly recovered or released through the rope outlet and avoiding as much as possible excessive friction between the pull rope 33 and the rope outlet during the process of being pulled out or wound, thereby reducing the service life of the pull rope 33.
[0047] In some embodiments, the winding wheel 32 further includes a rope-out guide wheel group (not shown in the figure) disposed at the rope-out port, the rope-out guide wheel group being disposed between the guide assembly and the winding wheel 32, and the rope-out guide wheel group including a first guide wheel and a second guide wheel, the first guide wheel and the second guide wheel being respectively fixedly mounted on both sides of the pull rope 33, and the outer peripheries of the first guide wheel and the second guide wheel being both provided with grooves at the same height, the two grooves being used to limit the rope-out direction of the pull rope 33. Since the rope-out port of the winding wheel 32 is at a certain distance from the guide assembly 60 disposed near the rope-out hole, when the user is doing strength training, the pull rope 33 is released or retracted back and forth, which is easily accompanied by shaking or jittering of the pull rope 33. In this way, by limiting the two grooves on both sides of the pull rope 33, shaking or jittering of the pull rope 33 during the process of being released or retracted back and forth can be reduced or avoided, thereby ensuring stability during strength training and improving the user's experience.
[0048] Preferably, the two grooves are used to limit the direction of the rope coming out of the pull rope 33 to be parallel to the plane where the rigid cover plate 20 is located. In order to ensure that the pull rope 33 can accurately enter the winding wheel 32 through the rope outlet and realize the winding of the pull rope 33, the groove of the first guide wheel at the rope outlet is limited to one side of the pull rope 33, and the groove of the second guide wheel at the rope outlet is limited to the other side of the pull rope 33. The two grooves clamp the limit pull rope 33, so that the pull rope 33 at the rope outlet is always parallel to the plane where the rigid cover plate 20 is located, that is, to ensure that the rope outlet and the pull rope 33 are always in the same plane, which reduces the sliding friction between the pull rope 33 and the rope outlet as much as possible, and facilitates the smooth winding and release of the pull rope 33.
[0049] It should be noted that the outgoing rope guide wheel set can be installed on the rigid cover plate 20 or on the winding wheel 32. After the outgoing rope guide wheel set is installed, the two grooves can be used to limit the outgoing rope direction of the pull rope 33 to be parallel to the plane where the rigid cover plate 20 is located.
[0050] As an optional embodiment, the number of guide assemblies 60 is two, and each guide assembly 60 includes a first guide wheel 61. The outer periphery of the first guide wheel 61 has a guide groove. The plane where the guide groove is located is perpendicular to the plane where the rigid cover plate 20 is located, and the guide direction of the guide groove is set to be collinear with the rope outlet direction of the corresponding winding wheel 32. The pull rope 33 extending from the winding wheel 32 passes through the corresponding guide groove and then passes through the rope outlet hole. The first guide wheel 61 is installed in a vertical state compared to the rigid cover plate 20, so that the plane where the guide groove of the first guide wheel 61 is located remains perpendicular to the plane where the rigid cover plate 20 is located. At the same time, in order to guide the pull rope 33, the guide direction of the guide groove is set to be collinear with the rope outlet direction of the corresponding winding wheel 32. The height of the first guide wheel 61 is basically flush with the height of the rope outlet of the winding wheel 32, so that the pull rope 33 located between the rope outlet and the guide groove basically maintains a state parallel to the rigid cover plate 20.
[0051] In some embodiments, the pull rope 33 extending from the winding wheel 32 is wound around a quarter of the circumference of the corresponding guide groove and then passes through the rope outlet hole.
[0052] As an optional embodiment, each guide assembly 60 further includes a second guide wheel, which is disposed on the second side of the rigid cover plate 20. The second guide wheel is used to guide the pull rope 33 passing through the rope outlet hole to meet different training postures and training movements of the user.
[0053] As an optional embodiment, a first mounting seat, a second mounting seat, a third mounting seat 22 and a fourth mounting seat 21 are formed on the first side of the rigid cover plate 20. The first mounting seat, the second mounting seat, the third mounting seat 22 and the fourth mounting seat 21 are all formed integrally with the rigid cover plate 20. The first mounting seat is used to install the tension component, the second mounting seat is used to install the electric control board 50, the third mounting seat 22 is used to install the guide component 60, and the fourth mounting seat 21 is used to install the support component 40. The support component 40 is used to support the strength training machine on the training ground. The support component 40 is arranged toward the lower base plate 10. The lower base plate 10 is provided with a through hole 11, and the support component 40 at least partially passes through the through hole 11.
[0054] On the one hand, the first mounting seat, the second mounting seat, the third mounting seat 22, and the fourth mounting seat 21 are all formed integrally with the rigid cover plate 20, further improving the rigidity of the rigid cover plate 20. On the other hand, the rigid cover plate 20 is multi-purpose, and the tension assembly, the guide assembly 60, and the support assembly 40 are all installed on the first side of the rigid cover plate 20, so that most of the weight of the whole machine is concentrated on the rigid cover plate 20, which greatly improves the rigidity of the whole machine as a whole and ensures the stability of the whole machine during training.
[0055] As an optional embodiment, the fourth mounting seat 21 has a mounting hole, and a threaded column or a threaded hole is arranged at the bottom of the mounting hole. The support assembly 40 includes a columnar support body, and the columnar support body has a step through hole formed along the axial direction. The columnar support body is inserted into the mounting hole and can be removably mounted on the threaded column or the threaded hole by bolts.
[0056] As another optional embodiment, a threaded column or a threaded hole is provided on the fourth mounting seat 21, and the support assembly 40 includes a columnar support body, and the support column body is fixedly provided with bolts along the axial direction, and can be detachably mounted on the threaded column or the threaded hole by the bolts. The columnar support body can be a plastic part or a part of a plastic part, and the plastic part contacts the training ground, which is conducive to protecting the training ground.
[0057] As an optional implementation, the rigid cover plate 20 is a metal cover plate. The material of the metal cover plate can be a steel plate, an alloy steel plate, an aluminum alloy plate, etc. It only needs to meet the rigidity requirements, and general metal materials have good thermal conductivity.
