Description

Technical Field

[0001] This application relates to the technical field of fitness equipment, and particularly to an orbital assembly, a locking assembly, and a trainer. Background Art

[0002] With the increasingly fast pace of modern life, people often need to be engaged in busy work, which also leads to people's growing attention to their own health. Therefore, fitness has become a popular sport for urban residents. On this basis, a comprehensive trainer appears. The comprehensive trainer generally includes a trainer body, an orbit, and a swing arm. The orbit is connected to the trainer body and can rotate horizontally relative to the trainer body. One end of the swing arm is slidably sleeved on the orbit, and the swing arm can swing vertically relative to the orbit. The trainer body is provided with a resistance supply device, and the resistance supply device is connected with a pull rope. The pull rope extends along the swing arm, so that the user can apply a force to the pull rope to overcome the resistance provided by the resistance supply device to do work and achieve the effect of strength training. In addition, the comprehensive trainer is also provided with a locking assembly for locking the orbit after adjusting the rotation angle of the orbit.

[0003] For existing comprehensive trainers, such as the Chinese patent application with the publication number CN 112384288 A and the publication date of February 19, 2021, discloses a training device, which mentions that a locking mechanism (the locking mechanism is the locking assembly) locks the position of a column (the column is the orbit), but this locking mechanism is a multi-link mechanism. Due to the long transmission route of the movement, it is easy to loosen when the locking mechanism locks the column. Summary of the Invention

[0004] In view of this, to solve the above technical problems, this application provides an orbital assembly, a locking assembly, and a trainer.

[0005] To solve the above technical problems, a technical solution adopted by this application is to provide an orbital assembly. The orbital assembly includes a locking assembly, an orbit, and a rotation-preventing mating gear disk. The rotation-preventing mating gear disk is fixedly arranged on the orbit. The locking assembly includes a fixed seat, a first ejector rod, a second ejector rod, and a driving assembly. The first ejector rod and the second ejector rod are respectively rotatably arranged on the fixed seat, and a space is formed between the first ejector rod and the second ejector rod. The driving assembly is used to drive the first ejector rod and the second ejector rod to rotate to change the size of the space between the ejector rods so that the first ejector rod and the second ejector rod are in a first state or a second state. Among them, in the first state, the first ejector rod abuts against the tooth flank on one side of the tooth of the rotation-preventing mating gear disk to prevent the forward rotation of the orbit, and the second ejector rod abuts against the tooth flank on the other side of the tooth of the rotation-preventing mating gear disk to prevent the reverse rotation of the orbit. In the second state, both the first ejector rod and the second ejector rod are disengaged from the rotation-preventing mating gear disk.

[0006] To solve the above technical problems, another technical solution adopted in this application is to provide a locking component, which is used to lock the track by cooperating with a rotation-preventing mating gear disk. The rotation-preventing mating gear disk is fixedly arranged on the track, and the locking component includes a fixed seat, a first ejector rod, a second ejector rod, and a driving component.

[0007] The first ejector rod and the second ejector rod are respectively rotatably arranged on the fixed seat, and a space is formed between the first ejector rod and the second ejector rod. The driving component is used to drive the first ejector rod and the second ejector rod to rotate to change the size of the space between the ejector rods so that the first ejector rod and the second ejector rod are in a first state or a second state. Among them, in the first state, the first ejector rod abuts against the tooth waist on one side of the tooth of the rotation-preventing mating gear disk to prevent the forward rotation of the track, and the second ejector rod can abut against the tooth waist on the other side of the tooth of the rotation-preventing mating gear disk to prevent the reverse rotation of the track. In the second state, both the first ejector rod and the second ejector rod are disengaged from the rotation-preventing mating gear disk.

[0008] To solve the above technical problems, another technical solution adopted in this application is to provide a trainer, which includes a trainer body, a track assembly, and a swing arm. The track assembly is the above-mentioned track assembly, and the swing arm is slidably arranged on the track of the track assembly.

[0009] Beneficial effects: Different from the prior art, in the first state, since the first ejector rod abuts against the tooth waist on one side of the tooth of the rotation-preventing mating gear disk, the reaction force of the force that hinders the forward rotation of the track between the first ejector rod and the rotation-preventing mating gear disk is conducted along the first ejector rod to the connection position between the first ejector rod and the fixed seat, pressing the first ejector rod and the fixed seat tightly, so that the first ejector rod is not easily loosened. In the first state, since the second ejector rod abuts against the tooth waist on the other side of the tooth of the rotation-preventing mating gear disk, the reaction force of the force that hinders the reverse rotation of the track between the second ejector rod and the rotation-preventing mating gear disk is conducted along the second ejector rod to the connection position between the second ejector rod and the fixed seat, pressing the second ejector rod and the fixed seat tightly, so that the second ejector rod is not easily loosened. Based on this, in the first state, the first ejector rod and the second ejector rod are not easily loosened due to the reaction force of the force that hinders the rotation of the track, making the locking of the first ejector rod and the second ejector rod to the track more firm. That is, the locking of the locking component to the track is more firm. Description of the Drawings

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] Refer to Figures 1-5 As shown, the trainer 10 includes a trainer body 100, a track assembly 200, a slider 300 and a swing arm 400. The track assembly 200 includes a locking assembly 210, a track 220 and an anti-rotation mating gear disk 230. The track 220 is disposed on the trainer body 100 and can rotate around the extension direction of the track 220. The anti-rotation mating gear disk 230 is fixedly disposed on the track 220. The locking assembly 210 is disposed on the trainer body 100 and is used to lock the track 220 by cooperating with the anti-rotation mating gear disk 230. The swing arm 400 is slidably disposed on the track 220 through the slider 300 and can swing relative to the slider 300 in the extension direction of the track 220.

[0029] In one example, the track 220 extends in the vertical direction, and the track 220 can rotate in the horizontal direction around the vertical direction. The swing arm 400 can swing in the vertical direction, but is not limited thereto. In another example, the track 220 can extend in the horizontal direction, and the track 220 can rotate in the vertical direction around the horizontal direction. In yet another example, the track 220 can extend in a direction that forms an acute or obtuse angle with the horizontal direction, the track 220 can rotate around the direction that forms an acute or obtuse angle with the horizontal direction, and the swing arm 400 can swing in the direction that forms an acute or obtuse angle with the horizontal direction.

[0030] Wherein, in combination Figures 1-2 Referring to Figures 3-5 As shown, the locking assembly 210 includes a fixed seat 211, a first ejector rod 212, a second ejector rod 213, and a driving assembly 214.

[0031] The fixed seat 211 can be fixedly arranged on the trainer body 100. The first ejector rod 212 and the second ejector rod 213 are respectively rotatably arranged on the fixed seat 211, and a ejector rod spacing space 215 is formed between the first ejector rod 212 and the second ejector rod. The driving assembly 214 is used to drive the first ejector rod 212 and the second ejector rod 213 to rotate to change the size of the ejector rod spacing space 215 so that the first ejector rod 212 and the second ejector rod 213 are in a first state or a second state. Wherein, in the first state, the first ejector rod 212 abuts against the tooth flank on one side of the tooth of the anti-rotation mating gear disk 230 to prevent the forward rotation of the track 220, and the second ejector rod 213 abuts against the tooth flank on the other side of the tooth of the anti-rotation mating gear disk 230 to prevent the reverse rotation of the track 220. In the second state, both the first ejector rod 212 and the second ejector rod 213 are disengaged from the anti-rotation mating gear disk 230.

[0032] In the above manner, when changing from the first state to the second state, the first ejector rod 212 and the second ejector rod 213 expand outward, causing the ejector rod spacing space 215 to expand, and further causing both the first ejector rod 212 and the second ejector rod 213 to be disengaged from the anti-rotation mating gear disk 230 to unlock the track 220 and allow the track 220 to rotate. When changing from the second state to the first state, the first ejector rod 212 and the second ejector rod 213 retract inward, causing the ejector rod spacing space 215 to shrink, and further causing the first ejector rod 212 to abut against the tooth flank on one side of the tooth of the anti-rotation mating gear disk 230, and the second ejector rod 213 to abut against the tooth flank on the other side of the tooth of the anti-rotation mating gear disk 230 to lock the track 220 and prevent the track 220 from rotating.

[0033] Among them, in the first state, since the first ejector rod 212 abuts against the tooth waist on one side of the tooth of the anti-rotation mating gear disk 230, thus, the reaction force of the force that hinders the forward rotation of the obstacle track 220 between the first ejector rod 212 and the anti-rotation mating gear disk 230 is conducted along the first ejector rod 212 to the connection position between the first ejector rod 212 and the fixed seat 211, pressing the first ejector rod 212 and the fixed seat 211 tightly, making it difficult for the first ejector rod 212 to loosen. Since in the first state, the second ejector rod 213 abuts against the tooth waist on the other side of the tooth of the anti-rotation mating gear disk 230, thus, the reaction force of the force that hinders the reverse rotation of the obstacle track 220 between the second ejector rod 213 and the anti-rotation mating gear disk 230 is conducted along the second ejector rod 213 to the connection position between the second ejector rod 213 and the fixed seat 211, pressing the second ejector rod 213 and the fixed seat 211 tightly, making it difficult for the second ejector rod 213 to loosen. Based on this, in the first state, the first ejector rod 212 and the second ejector rod 213 are not easily loosened due to the reaction force of the force that causes the obstacle track 220 to rotate, making the locking of the first ejector rod 212 and the second ejector rod 213 to the track 220 more firm. That is, the locking component locks the track more firmly.

[0034] It should be understood that the combination of the track 220 and the anti-rotation mating gear disk 230 is a component, and the anti-rotation mating gear disk 230 rotates synchronously with the track 220. The track 220 rotates around the arrangement direction of the anti-rotation mating gear disk 230 and the track 220. Among them, the forward rotation and the reverse rotation of the track 220 are a pair of rotations in opposite directions. In one example, taking Figure 3 the clockwise rotation in it as the forward rotation, then Figure 3 the counterclockwise rotation in it is the reverse rotation. Of course, in another example, taking Figure 3 the counterclockwise rotation in it as the forward rotation, then Figure 3 the clockwise rotation in it is the reverse rotation.

[0035] Optionally, in one example, in combination with Figures 3-5 refer to Figures 1-2 , the anti-rotation mating gear disk 230 is arranged at the end of the track 220, and anti-rotation mating gear disks 230 and corresponding locking components 210 are arranged at both ends of the track 220, but not limited to this. The locking component 210 is used to cooperate with the corresponding anti-rotation mating gear disk 230 to lock the track 220. In another example, the anti-rotation mating gear disk 230 can be arranged in the middle section of the track 220 or other places between the middle section and the end of the track 220. Taking the anti-rotation mating gear disk 230 arranged at the end of the track 220 as an example for description, the trainer 10 may include a gear disk transfer shaft 234, and the anti-rotation mating gear disk 230 can be rotatably arranged on the trainer body 100 through the gear disk transfer shaft 234 so that the track 220 can rotate, but not limited to this.

[0036] Optionally, in one example, in combination withFigures 3-5 Refer to Figures 6-7 , the anti-rotation mating gear disk 230 can be a circular or sector gear disk, but is not limited thereto. In another example, the anti-rotation mating gear disk 230 includes a plate body portion 231 and a tooth portion 232. The outer periphery of the plate body portion 231 has an arc-shaped outer edge, and a plurality of tooth portions 232 are arranged on the arc-shaped outer edge and are spaced along the arc-shaped outer edge. Further, the anti-rotation mating gear disk 230 includes a plurality of transfer posts 233. The transfer posts 233 protrude from one side of the end of the plate body portion 231 facing the track 220. A plurality of transfer holes 221 are provided at the end of the track 220, and the plurality of transfer posts 233 are correspondingly inserted into the plurality of transfer holes 221 to fix the anti-rotation mating gear disk 230 to the end of the track 220.

[0037] Further, in the trainer 10 disclosed in the Chinese patent with the publication number CN 112384288 A, the locking mechanism is a multi-link transmission mechanism. Since the movement transmission route of this multi-link mechanism is relatively long, it is easy to produce large error accumulation, resulting in a transmission dead point and causing the mechanism to jam. In this regard, in the trainer 10 of the present invention, in combination with Figures 3-5 Refer to Figures 6-7 , the driving assembly 214 includes an elastic assembly 21, a toggle switch 22, and a driving member 23.

[0038] The elastic assembly 21 elastically supports the first ejector rod 212 and the second ejector rod 213 respectively. The toggle switch 22 is movably arranged on the fixed seat 211 and extends into the ejector rod spacing space 215 for respectively abutting against the first ejector rod 212 and the second ejector rod 213. The driving member 23 is fixed on the fixed seat 211 and is used to drive the toggle switch 22 to rotate or displace to toggle the first ejector rod 212 and the second ejector rod 213 to rotate in the direction of enlarging the ejector rod spacing space 215, so that the first ejector rod 212 and the second ejector rod 213 are in the second state and the elastic assembly 21 is deformed by force. When the driving member 23 releases the toggle switch 22, the elastic restoring force of the elastic assembly 21 drives the first ejector rod 212 and the second ejector rod 213 to rotate in the direction of reducing the ejector rod spacing space 215, so that the first ejector rod 212 and the second ejector rod 213 are in the first state.

[0039] In the above manner, the connection between the toggle switch 22 and the first ejector rod 212, and the connection between the toggle switch 22 and the second ejector rod 213 are both detachable abuts, so that it is not easy for the toggle switch 22 and the first ejector rod 212 or the toggle switch 22 and the second ejector rod 213 to jam. In addition, the toggle switch 22, the first ejector rod 212, the second ejector rod 213, and the driving member 23 are all independently installed on the fixed seat 211. Therefore, during the transmission process of the driving member 23 to the first ejector rod 212 and the second ejector rod 213 through the toggle switch 22, errors are not easy to accumulate, and thus it is not easy to generate a transmission dead point.

[0040] Further, in combination with Figures 3-5 refer to Figures 6-7 , the driving member 23 is used to drive the toggle switch 22 to rotate. The fixed seat 211 has a first side surface 31 and a second side surface 32 arranged opposite to each other. The first ejector rod 212 and the second ejector rod 213 are rotatably arranged on the first side surface 31, and the driving member 23 is arranged on the second side surface 32 and has a push rod 24. The toggle switch 22 includes a rotating shaft 41, a toggle lever 42 and a linkage toggle lever 43.

[0041] The rotating shaft 41 is rotatably arranged on the fixed seat 211. The toggle lever 42 is arranged on the rotating shaft 41 and is located on the first side surface 31 of the fixed seat 211. The toggle lever 42 is used to respectively abut against the first ejector rod 212 and the second ejector rod 213. The linkage toggle lever 43 is fixedly arranged on the rotating shaft 41 and is located on the second side surface 32. The linkage toggle lever 43 is used to abut against the push rod 24. Wherein, the driving member 23 is used to drive the push rod 24 to extend or retract, and further drive the toggle lever 42 to rotate in the direction of enlarging the space between the ejector rods 215 by the abutment between the push rod 24 and the linkage toggle lever 43, so as to outwardly expand the first ejector rod 212 and the second ejector rod 213 by both ends of the toggle lever 42.

[0042] In the above way, the driving member 23 and the linkage toggle lever 43 are arranged on the side where the second side surface 32 is located, and the first ejector rod 212, the second ejector rod 213 and the toggle lever 42 are arranged on the side where the first side surface 31 is located, so that it is possible to avoid overcrowding of components and facilitate assembly. Optionally, the driving member 23 is a solenoid valve or a motor. Preferably, the driving member 23 is an electromagnet. In this way, when the electromagnet releases the toggle switch, no power supply is required, which is more power-saving.

[0043] Further, in combination with Figures 3-5 refer to Figures 6-7 , the driving assembly 214 includes a rolling member 25. The rolling member 25 is arranged on the push rod 24, and the push rod 24 abuts against the linkage toggle lever 43 through the rolling member 25. In this way, the push rod 24 abuts against the linkage toggle lever 43 through the rolling member 25, which can reduce friction and improve service life. Optionally, the rolling member 25 is a roller. Optionally, the push rod 24 abuts against the linkage toggle lever 43 through two rollers.

[0044] Further, in combination with Figures 3-5 refer to Figures 6-7 , the toggle lever 42 has a third state when the first ejector rod 212 and the second ejector rod 213 are in the first state, and the toggle lever 42 has a fourth state when the first ejector rod 212 and the second ejector rod 213 are in the second state. The third state causes the toggle lever 42 to disengage from the first ejector rod 212 and the second ejector rod 213, and the fourth state causes the toggle lever 42 to respectively abut against the first ejector rod 212 and the second ejector rod.

[0045] In the above manner, when the first top rod 212 and the second top rod 213 are in the first state, the toggle rod 42 is in the third state, and the toggle rod 42 is separated from the first top rod 212 and the second top rod 213, so that the deformation and force transmission caused by the shaking of the swing arm 400 will not affect the toggle rod 42. That is, when the first top rod 212 and the second top rod 213 are in the first state, the deformation and force transmission caused by the shaking of the swing arm 400 will not affect the toggle switch 22 and the driving member 23, thereby improving the service life of the toggle switch 22 and the driving member 23.

[0046] Furthermore, combined with Figures 3-5 See also Figures 6-7 The fixing seat 211 is provided with a rotating shaft through hole 33, and the driving assembly 214 includes at least two bearings 26 and a shaft clamp 27. At least two bearings 26 are provided in the rotating through hole, and the rotating shaft 41 is provided in the at least two bearings 26. The shaft clamp 27 is provided in the fixing seat 211 and is engaged with a bearing 26 away from the toggle rod 42 among at least two bearings 26 to prevent at least two bearings 26 from escaping from the rotating shaft through hole 33. In this way, the rotating connection between the rotating shaft 41 and the rotating through hole is realized through at least two bearings 26, so that the rotation of the rotating shaft 41 can be more stable and not easy to shake.

[0047] Optionally, the toggle lever 42 and the rotating shaft 41 are locked by a first screw 44, and a first gasket 45 is sleeved on the portion of the rotating shaft between the toggle lever 42 and the bearing 26, and the outer diameter of the first gasket 45 is smaller than the inner diameter of the outer ring of the bearing 26 and larger than the inner diameter of the inner ring of the bearing 26. The first gasket 45 is used to support the toggle lever 42 so that the toggle lever 42 is spaced apart from the outer ring of the bearing 26. In this way, the first gasket 45 can avoid wear caused by friction between the toggle lever 42 and the outer ring of the bearing 26.

[0048] Optionally, the driving assembly 214 includes a driving member casing 216, and the driving member casing 216 is sleeved outside the driving member 23. In this way, the driving member casing 216 can play a certain dustproof role on the driving member 23.

[0049] Furthermore, combined with Figures 3-5 See also Figures 6-7 The fixing seat 211 includes a receiving groove portion 34 , a supporting platform portion 35 and a mounting column portion 36 .

[0050] A receiving groove 37 is provided on the first side surface 31 of the receiving groove portion 34, and the receiving groove 37 extends to the end surface of the receiving groove portion 34 facing the anti-rotation engaging gear disk 230. The mounting post is located in the receiving groove 37 and protrudes from the bottom wall of the receiving groove 37. The rotating shaft through hole 33 penetrates through the mounting post and the bottom wall of the receiving groove 37. The supporting platform portion 35 is provided at one end of the receiving groove 37 away from the anti-rotation engaging gear disk 230. One end of the first ejector rod 212 is rotatably provided on the supporting platform portion 35. The other end of the first ejector rod 212 extends through the receiving groove portion 34 towards the anti-rotation engaging gear disk 230 to the outside of one end of the receiving groove portion 34 close to the anti-rotation engaging gear disk 230. One end of the second ejector rod 213 is rotatably provided on the supporting platform portion 35, and the other end of the second ejector rod 213 extends through the receiving groove portion 34 towards the anti-rotation engaging gear disk 230 to the outside of one end of the receiving groove portion 34 close to the anti-rotation engaging gear disk 230. Wherein, the supporting platform portion 35 supports the first ejector rod 212 and the second ejector rod 213, so that the portion of the first ejector rod 212 located in the receiving groove 37 is spaced from the bottom wall of the receiving groove 37, and the portion of the second ejector rod 213 located in the receiving groove 37 is spaced from the bottom wall of the receiving groove 37.

[0051] In the above manner, the portion of the first ejector rod 212 located in the receiving groove 37 and the portion of the second ejector rod 213 located in the receiving groove 37 are both spaced from the bottom wall of the receiving groove 37. In this way, it is possible to avoid the wear caused by the friction between the first ejector rod 212 and the second ejector rod 213 and the bottom wall of the receiving groove 37 during the rotation process, thereby extending the service life.

[0052] Furthermore, in combination with Figures 3-5 refer to Figures 6-7 , the elastic component 21 includes a first spring 51 and a second spring 52. A first limiting post 53 is provided on one side surface of the first ejector rod 212 facing away from the ejector rod spacing space 215. A second limiting post (not shown in the figure) is provided on the side wall of the receiving groove 37 on the side of the first ejector rod 212 facing away from the ejector rod spacing space 215.
