Description

Technical Field

[0001] The invention relates to the technical field of sports equipment, in particular to an electric abdominal wheel. Background Art

[0002] The abdominal wheel is a fitness equipment for exercising human muscles and joints. The traditional abdominal wheel adopts a combination of rollers and handles. For most users, especially those with weak waist and abdomen strength (including women and obese people), they need to use greater force when the abdominal wheel returns, resulting in energy loss, shortening the effective fitness time and reducing fitness efficiency. At present, there are some power-assisted rebound ab wheels on the market. One type of them is to add a torsion spring to the original structure so that the user can overcome the resistance of the torsion spring when pushing forward and rely on the rebound force of the torsion spring to assist and save effort when pulling back. However, it cannot provide power assistance when pushing out, and the torque output of the mechanical rebound spring is unstable. It is prone to breakage or deformation after long-term use. The distance moved each time by the ab wheel is different, making it difficult to control the required force, affecting the fitness effect; the other type is to set sensors and power devices in the structure. For example, a distance sensor is set. After the user pushes forward to a fixed distance, the power device drives the roller to rotate when pulling back to complete the rebound assist function, thereby realizing the electric rebound of the ab wheel. However, it needs to be pushed to a fixed distance to realize the rebound assistance of the ab wheel. The user cannot flexibly control and realize the back and forth assistance activity of the ab wheel according to his own situation. It is easy to fail to push to the set distance due to lack of physical strength, which may lead to dangerous situations, thereby affecting the fitness effect and the personal safety of the user. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example 1

[0036] Combined with Figure 1-12 The present embodiment provides an electric abdominal wheel, comprising: a roller 1, wherein the roller 1 has a housing 2, wherein a power supply 3, a driving motor 4 and a controller 5 are arranged inside the housing 2, wherein the driving motor 4 is electrically connected to the controller 5, and wherein two induction switches 6 are arranged on the controller 5; a handle, wherein the handle comprises a handle A and a handle B, wherein the handle A and the handle B are respectively arranged at two ends of the housing 2, wherein the handle A comprises a movable outer shaft 7 and a fixed inner shaft 8, wherein the movable outer shaft 7 is movably sleeved on the fixed inner shaft 8, and wherein the movable outer shaft 7 and the fixed inner shaft 8 are sleeved together. When the shafts 8 rotate relative to each other, a corresponding rotation angle is formed. The fixed inner shaft 8 is fixedly connected to the drive motor 4. The controller 5 is fixed on the fixed inner shaft 8. Two electric coupling adjustment sheets 9 are installed on the movable outer shaft 7. A spring 10 is provided on the outer sleeve of the electric coupling adjustment sheet 9. The induction switch 6 is arranged corresponding to the electric coupling adjustment sheet 9. By rotating the movable outer shaft 7 and adjusting the rotation angle, the electric coupling adjustment sheet 9 is controlled to trigger the corresponding induction switch 6 on the controller 5, so that the induction switch 6 is turned on, thereby controlling the forward or reverse rotation of the drive motor 4.

[0037] In this embodiment, after the user turns on the power switch 3, when the movable outer shaft 7 of the adjustment handle A rotates clockwise by a corresponding angle relative to the fixed inner shaft 8 (handle B), one of the electric coupling adjustment pieces 9 triggers the corresponding induction switch 6 on the controller 5, so that the induction switch 6 is turned on, and then the controller 5 is triggered to control the drive motor 4 to rotate forward, so that the abdominal wheel moves forward; when the movable outer shaft 7 of the handle A rotates counterclockwise by a corresponding angle relative to the fixed inner shaft 8 (handle B), another electric coupling adjustment piece 9 triggers the corresponding induction switch 6 on the controller 5, so that the induction switch 6 is turned on, and then the controller 5 is triggered to control the drive motor 4 to reverse, so that the abdominal wheel moves backward; when the movable outer shaft 7 of the handle A is not adjusted to rotate (that is, when the rotation angle is zero), since the electric coupling adjustment piece 9 has a spring 10, under the action of the spring 10, the electric coupling adjustment piece 9 is in a balanced state and will not trigger the induction switch 6 on the controller 5, and cannot trigger the controller 5 to control the drive motor 4 to rotate. With the electric abdominal wheel, the user only needs to slightly rotate the movable outer shaft 7 of the handle to adjust the electric coupling adjustment plate 9 to trigger the corresponding induction switch 6, so that the induction switch 6 is turned on, and the trigger controller 5 controls the forward or reverse rotation of the driving motor 4, thereby realizing the sensitive and smooth back and forth assisted movement of the abdominal wheel, helping people with insufficient waist and abdominal strength to complete standard abdominal wheel movements, and improving the user's fitness effect.

[0038] Example 2

[0039] Combined with Figure 1-12 , compared with the technical solution of Example 1, the electric abdominal wheel of this embodiment has an adjustment range of the rotation angle of 3-6 degrees. When the rotation angle is less than 3 degrees, the electric coupling adjustment piece 9 on the movable outer shaft 7 cannot trigger the induction switch 6 on the controller 5, and thus cannot trigger the controller 5 to control the rotation of the drive motor 4; if the rotation angle is greater than 6 degrees, the user needs to rotate the movable outer shaft 7 relative to the fixed inner shaft 8 to a large extent, especially when the user is physically exhausted. Due to the large rotation amplitude, it is difficult for the user to flexibly control the abdominal wheel, causing inconvenience to the user. In actual use, the rotation angle is 5 degrees. This setting is based on the habit of people pushing out their hands and turning their wrists up when pulling back and pressing their wrists down. The user only needs to slightly rotate the movable outer shaft 7 of the handle to adjust the electric coupling adjustment piece 9 to trigger the corresponding induction switch 6, thereby realizing the sensitive back and forth power-assisted movement of the abdominal wheel.

[0040] Example 3

[0041] Combined with Figure 1-12 , an electric abdominal wheel of this embodiment, compared with the technical solution of embodiment 1, such as Figure 4-8As shown, first mounting plates 11 are respectively installed on both sides of one end of the fixed inner shaft 8, the first mounting plate 11 has a first through hole 12, and two through hole columns 13 are provided at one end of the first mounting plate 11 away from the fixed inner shaft 8, and a second mounting plate 14 is installed on the upper surface of the fixed inner shaft 8, a first threaded hole 15 is provided in the middle part of the second mounting plate 14, and first grooves 16 are respectively provided at both ends of the second mounting plate 14, the first groove 16 is arranged corresponding to the first through hole 12, and second threaded holes 17 are respectively provided on both sides of the first groove 16.

[0042] In this embodiment, the controller 5 is mounted on the second mounting plate 14, and the two inductive switches 6 pass through the first grooves 16 respectively. At this time, the two electric coupling adjustment sheets 9 mounted on the movable outer shaft 7 pass through the first through holes 12 of the first mounting plate 11 arranged on both sides of the fixed inner shaft 8 respectively. Since the first grooves 16 are arranged correspondingly to the first through holes 12, the two inductive switches 6 correspond to the two electric coupling adjustment sheets 9 on the movable outer shaft 7 respectively, and there is a gap between the inductive switches 6 and the electric coupling adjustment sheets 9. The through hole column 13 on the first mounting plate 11 is used for the installation and fixation of the power supply 3, and the power supply 3 is fixed on the fixed inner shaft 8. This arrangement makes the entire structure more compact.

[0043] Example 4

[0044] Combined with Figure 1-12 Compared with the technical solution of embodiment 3, the electric abdominal wheel of this embodiment has the following advantages: Figure 9-10 As shown, an extension portion 18 is provided on the lower surface of one end of the movable outer shaft 7, and the extension portion 18 has a step structure. A protrusion 19 is provided on the outer surface of the extension portion 18, and a third threaded hole 20 is provided on the protrusion 19. This arrangement enables an adjustment gap to be formed between the step structure of the extension portion 18 and the first mounting plates 11 on both sides of the fixed inner shaft 8 when the movable outer shaft 7 is sleeved on the fixed inner shaft 8, that is, the adjustment gap between the movable outer shaft 7 and the fixed inner shaft 8 is defined, and the size of the adjustment gap can further define the size of the rotation angle formed when the movable outer shaft 7 rotates relative to the fixed inner shaft 8.

[0045] In actual use, the size of the adjustment gap is 1.5-2.5mm. When the adjustment gap is less than 1.5mm, due to the small gap, the angle of rotation of the movable outer shaft 7 relative to the fixed inner shaft 8 is relatively small, and the electric coupling adjustment piece 9 on the movable outer shaft 7 cannot trigger the induction switch 6 on the controller 5; if the gap is greater than 2.5mm, the angle of rotation of the movable outer shaft 7 relative to the fixed inner shaft 8 will be large, and the user needs to rotate the movable outer shaft 7 relative to the fixed inner shaft 8. The amplitude will be large, making it impossible for the user to flexibly control the movement of the abdominal wheel when he is physically exhausted, causing inconvenience to the user. In addition, the electric coupling adjustment piece 9 is fixed to the protrusion 19 through the third threaded hole 20 by a screw, and then fixed to the movable outer shaft 7.

[0046] In actual use, sliding bearings are provided at both ends of the movable outer shaft 7 , which facilitates the relative rotation between the movable outer shaft 7 and the fixed inner shaft 8 .

[0047] Example 5

[0048] Combined with Figure 1-12 Compared with the technical solution of embodiment 4, the electric abdominal wheel of this embodiment has the following advantages: Fig.12 As shown, the electric coupling adjustment sheet 9 is arranged on the upper surface of the electric coupling adjustment plate 21 , and the electric coupling adjustment plate 21 has a fourth threaded hole 22 .

[0049] In actual use, there are two fourth threaded holes 22 on the electric coupling adjustment plate 21, and there are two third threaded holes 20 on the protrusion 19. The electric coupling adjustment plate 21 is fixed to the movable outer shaft 7 by screws passing through the fourth threaded holes 22 and the third threaded holes 20, thereby fixing the electric coupling adjustment plate 9 on the movable outer shaft 7.

[0050] Example 6

[0051] Combined with Figure 1-12 In this embodiment, compared with the technical solution of embodiment 1, the inductive switch is a photoelectric coupling switch, the photoelectric coupling switch has a second groove, and the electric coupling adjustment sheet 9 cooperates with the second groove. This setting can increase the sensitivity of the inductive switch 6 and the electric coupling adjustment sheet 9 being connected, and can quickly trigger the controller 5 to control the forward and reverse rotation of the motor.

[0052] Example 7

[0053] Combined with Figure 1-12 Compared with the technical solution of embodiment 3, the electric abdominal wheel of this embodiment has the following advantages: Fig.11 As shown, the driving motor 4 is a brushless DC motor, and the driving motor 4 includes an outer rotor 24 and a motor shaft 25 . The handle A and the handle B are fixedly connected to two ends of the motor shaft 25 , respectively.

[0054] In this embodiment, if Figure 8 As shown, the fixed inner shaft 8 has a first cavity, one end of the fixed inner shaft 8 has a first wire hole 26 that runs through from top to bottom, and the upper surface of one end of the fixed inner shaft 8 is provided with a fifth threaded hole 27, and the fifth threaded hole 27 is arranged corresponding to the first threaded hole 15 on the second mounting plate 14; the motor shaft 25 of the driving motor 4 has a second cavity, one end of the motor shaft 25 is provided with a sixth threaded hole 28 and a second wire hole 29 that runs through from top to bottom, and the other end is provided with a seventh threaded hole 30; the fixed inner shaft 8 of the handle A passes through the first threaded hole 15 on the mounting plate by screws, the fifth threaded hole 27 on the fixed inner shaft 8 and the sixth threaded hole 28 on the motor shaft 25 are fixed to one end of the motor shaft 25, and one end of the handle B is fixed to the seventh threaded hole 30 at the other end of the motor shaft 25 by screws. This arrangement allows the handles A and B to be stably fixed at both ends of the driving motor 4.

[0055] Example 8

[0056] Combined with Figure 1-12 Compared with the technical solution of Example 1, the electric abdominal wheel of this embodiment has a display electrically connected to the controller 5 at the end of the handle. The display is arranged on the handle end cover, and the display is arranged to display the power-on state and the running state of the abdominal wheel. In actual use, the number of displays is 2, which are respectively arranged on both sides of the controller 5.

[0057] In actual use, the electric abdominal wheel also includes a first end cover 31 and a second end cover 32, which are respectively arranged on the two side surfaces of the outer rotor 24 of the driving motor 4, and the roller 1 includes a hub 33 and a rubber ring 34, which is sleeved on the hub 33, and the two sides of the hub 33 are respectively fixedly connected to the outer periphery of the first end cover 31 and the second end cover 32, and the hub 33 is located above the outer surface of the outer rotor 24 of the driving motor 4. The setting of the rubber ring 34 can not only reduce noise, but also increase the friction between the roller 1 and the ground. The outer surface of the hub 33 is partially provided with a rubber ring 34, and the hub 33 is made of transparent material. This setting can clearly see the display status of the display.

[0058] Example 9

[0059] Combined with Figure 1-12 Compared with the technical solution of Example 1, the electric abdominal wheel of this embodiment has a power switch and a charging port connected to the power source 3 at the end of the handle. The power source 3 switch and the charging port are arranged on the end cover of the handle, and the arrangement is used to control the switch of the power source 3, so as to facilitate charging the power source 3.

[0060] Example 10

[0061] Combined with Figure 1-12 Compared with the technical solution of Example 1, the electric abdominal wheel of this embodiment has a speed regulating knob at the end of the handle. The speed regulating knob is set on the end cover of the handle, and the speed of the abdominal wheel can be adjusted by setting different gears of the speed regulating knob to meet the user's speed requirements.

[0062] After the user starts the power switch 3, according to their own needs, adjust the speed knob, and after adjusting to the appropriate gear, the movable outer shaft 7 of the adjustment handle A rotates 3-6 degrees clockwise relative to the fixed inner shaft 8 (handle B), so that one of the electric coupling adjustment pieces 9 triggers the corresponding induction switch 6 on the controller 5, so that the induction switch 6 is turned on, and then the controller 5 is triggered to control the drive motor 4 to rotate forward, so that the abdominal wheel moves forward; when it is necessary to pull back, the movable outer shaft 7 of the adjustment handle A rotates 3-6 degrees counterclockwise relative to the fixed inner shaft 8 (handle B). At this time, another electric coupling adjustment piece 9 is turned on with the corresponding induction switch 6 on the controller 5, which triggers the controller 5 to control the drive motor 4 to reverse, so that the abdominal wheel moves backward; when no power is needed, there is no need to rotate the adjustment handle A. Since the electric coupling adjustment piece 9 has a spring 10, under the action of the spring 10, the electric coupling adjustment piece 9 is in a balanced state and cannot trigger the induction switch 6 on the controller 5, and then cannot trigger the controller 5 to control the drive motor 4 to rotate, and the user can exercise like a normal abdominal wheel. With the electric abdominal wheel of this arrangement, the user only needs to slightly rotate the movable outer shaft 7 of the handle to adjust the electric coupling adjustment plate 9 to trigger the corresponding induction switch 6, and the trigger controller 5 controls the forward or reverse rotation of the driving motor 4, thereby realizing sensitive and smooth back and forth assisted movement of the abdominal wheel, helping people with insufficient waist and abdominal strength to complete standard abdominal wheel movements, and improving the user's fitness effect.

[0063] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
