Detailed Description
To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1 to 4, an embodiment of the hydraulic cylinder device of the exercise apparatus of the present invention includes a hydraulic cylinder unit 1, a driving unit 2, a fixing unit 3, and a control unit 4.
The hydraulic cylinder unit 1 includes a hydraulic cylinder body 11, a piston rod 12 movably disposed in the hydraulic cylinder body 11 and generating resistance during movement, and an adjusting rod 13 for adjusting the resistance. The hydraulic cylinder unit 1 is a hydraulic cylinder assembly with adjustable resistance, belongs to the prior art, and is not described in detail herein.
The driving unit 2 is disposed on the hydraulic cylinder unit 1 and is used for driving the adjusting rod 13. The driving unit 2 includes a connecting shaft 22 rotatable around its axis and connected to the adjusting lever 13, and a driver 21 for driving the connecting shaft 22 to rotate. In the present embodiment, the driver 21 is a motor.
In this embodiment, the connecting shaft 22 is sleeved outside the adjusting rod 13, and the outer peripheral profile of the radial cross section of the adjusting rod 13 is substantially quadrilateral, the outer peripheral profile of the radial cross section of the connecting shaft 22 is substantially hexagonal, and the inner peripheral profile is quadrilateral consistent with the outer peripheral profile of the radial cross section of the adjusting rod 13, so as to prevent the connecting shaft 22 from idling when the driver 21 drives the connecting shaft 22 to rotate. However, in other variations, the outer circumferential profile of the radial cross section of the adjustment lever 13 and the connecting shaft 22 may be triangular, pentagonal, or other polygonal shape.
The fixing unit 3 is used to fix the driving unit 2 to the hydraulic cylinder unit 1. The fixing unit 3 includes a fixing plate 31 disposed on the hydraulic cylinder body 11, a connecting plate 32 connected to the fixing plate 31 and the driving unit 2, and a reinforcing plate 33 disposed on the fixing plate 31 and used for fixing the fixing plate 31 to the hydraulic cylinder body 11. The fixing plate 31 has a fixing portion 311 disposed on the cylinder body 11, and a plurality of extending portions 312 extending outward from the periphery of the fixing portion 311. The connecting piece 32 is substantially L-shaped and has a connecting body 321 disposed on the driver 21, and a connecting portion 322 extending outward from the connecting body 321 and connected to one of the extending portions 312, wherein the connecting portion 322 is used for being fixedly connected with the extending portion 312. The reinforcing plate 33 is fixed to the fixing portion 311 of the fixing plate 31. The cylinder body 11, the fixing portion 311 and the extending portion 312 of the fixing piece 31, the connecting body 321 and the connecting portion 322 of the connecting piece 32, and the reinforcing piece 33 are all provided with mounting holes for fixedly connecting with each other, and are fixedly connected by a connecting piece; such as: the mounting holes are threaded holes for screw-lock fixed connection by bolts, or are riveting holes for press-riveting fixed connection by rivets, etc.
