Description

Technical Field

[0001] The present invention relates to the field of fitness equipment, and specifically to a type of power station.

Background Art

[0002] A power station is a household smart resistance training device that provides adjustable resistance by means of a built-in motor and can achieve the same muscle strength training effect as conventional training equipment such as dumbbells and barbells. This enables full-body resistance training to be carried out at home. Generally, such a device consists of a base and two latch cords, and exercises are performed by pulling the latch cords. It is suitable for home use and, especially for users who lack training equipment but want to perform muscle strength training, it is an effective solution to replace conventional equipment such as dumbbells and barbells and can exercise all muscle groups in the body.

[0003] The power station can be referred to in the Chinese patent document with the publication number CN223287552U. However, the rope exit position of the conventional power station is usually fixed, and the force direction of the rope corresponding to different training modes cannot be adjusted, making it difficult to adapt to different usage situations.

[0004] Furthermore, fitness equipment using elastomer bands also exists today (for example, Chinese patent document number CN214808235U). This equipment has a base plate on which a footplate and multiple elastomer band connection points are provided. The inclusion of a footplate encourages users to place their feet in designated positions on the base plate while training, resulting in more effective exercise. While the above fitness equipment allows users to change the muscle groups being trained and achieve diverse training effects by attaching elastomer bands to connection points at different locations, it lacks the function of automatically winding up and storing the latch cord, as seen in conventional power stations, resulting in cumbersome handling and storage after use, making it inconvenient to use.

[0006] Therefore, a type of power station capable of solving the following problems is needed: 1. The problem that conventional power stations cannot adjust the tension direction of the latch cord. 2. The problem that the latch cord cannot be wound up in the above-mentioned elastomer band type fitness equipment. [Means for solving the problem]

[0007] The contents of this invention are intended to briefly introduce the concept, which will be explained in detail in the section on specific implementations described later. The contents of this patent are not intended to identify important or necessary features of the technical solution for which protection is sought, nor are they intended to limit the scope of the technical solution for which protection is sought.

[0008] To solve the technical problems described in the background technology section above, some embodiments of the present invention provide a power station having the following configuration: The main body has an upper surface and a lower surface, as well as a housing space formed between the upper and lower surfaces. A pair of grips are provided, each to which a latch cord is connected. One end of the latch cord is connected to the grip, and the other end is located in the housing space. A first rail is fixedly installed on the main body along a predetermined trajectory, and this first rail has a sliding slider, to which the latch cord is connected to the grip via the slider.

[0009] Furthermore, the upper surface of the main body is provided with a support area for assuming a supine, seated, or standing posture, and the support area has a front boundary line and a rear boundary line extending in the front-rear direction, and a left boundary line and a right boundary line extending in the left-right direction, and the first rail includes a portion that extends along the left boundary line and the right boundary line, and a portion that extends along the front boundary line.

[0010] Furthermore, both the trajectory of the left boundary line and the trajectory of the right boundary line are arc-shaped.

[0011] Furthermore, two first guide wheels are rotatably provided inside the main body to guide the latch cord.

[0012] Furthermore, the trajectories of the left and right boundary lines are semicircular, with one first guide wheel positioned at the center of the left boundary line's trajectory and the other first guide wheel positioned at the center of the right boundary line's trajectory.

[0013] Furthermore, a connecting head is attached to the slider, and the latch cord passes through this connecting head.

[0014] Furthermore, the top surface of the main unit is provided with a slot for the latch cord that matches the trajectory of the first rail, and the connecting head passes through this latch cord slot.

[0015] Furthermore, a second rail is fixedly installed inside the main body, located below the first rail, and the second rail has the same trajectory as the first rail. A mounting block is slidably connected to the second rail, and one end of the connecting head is inserted into the mounting block and slidably fitted to the mounting block. A lower block is also provided below the second rail, and the lower block is fixed to the mounting block. The second rail has a slot that extends along its trajectory, and the connecting head passes through the slot. A spring is provided between the connecting head and the lower block, and a retaining ring is attached to the connecting head. The outer diameter of the retaining ring is set to be larger than the width of the slot, and both ends of the spring are connected to the lower block and the retaining ring, respectively. Multiple pairs of locking grooves are provided at equal intervals along the trajectory of the second rail on the side wall of the slot, and the lower side of the locking grooves is open. A part of the retaining ring is fitted into one of the pairs of locking grooves.

[0016] Furthermore, a second guide wheel, which guides the latch cord, is rotatably mounted on the lower block. [Effects of the Invention]

[0017] 1. By adjusting the position of the slider, the extraction position of the latch code can be changed, and accordingly, the resistance direction generated by the latch code can be adjusted. This makes it easier to perform exercises corresponding to different training modes, and at the same time, the winding of the latch code can be realized.

[0018] 2. After adjusting the extraction position of the latch code by the installed connection head, second rail, lower block, and installation block, the fixed ring fits into the locking groove, thereby fixing the extraction position of the latch code and preventing the extraction position of the latch code from fluctuating during training.

[0026] The present disclosure will be described in detail below based on embodiments with reference to the drawings.

[0027] Referring to Figures 1 to 9, a power station comprises a main body 11, a grip 14, a latch code slot 15, a first rail 16, a mounting area 12, a front boundary line 31, a rear boundary line 32, a left boundary line 33, and a right boundary line 34. The main body 11 has an upper surface and a lower surface, as well as a storage space formed between the upper and lower surfaces. The upper surface of the main body 11 is provided with a mounting area 12 for assuming a supine, seated, or standing posture. The outer shape of this mounting area 12 is like that of a track and field stadium, and its boundaries are composed of a front boundary line 31 and a rear boundary line 32 that are parallel to each other, and a left boundary line 33 and a right boundary line 34 that form semicircles, respectively. The first rail 16 is attached to the main body 11, and this first rail 16 includes a portion that extends along the left boundary line 33 and the right boundary line 34, and a portion that extends along the front boundary line 31. In addition, the upper surface of the main body 11 is provided with a latch code slot 15 that coincides with the trajectory of the first rail 16. The main body 11 is provided with a pair of grips 14, each grip 14 to which a latch cord is connected, one end of which is installed within a storage space. A slider 17 is slidably connected to the first rail 16, and the latch cord passes through this slider 17 before connecting to the grips 14. The latch cord is pulled out to the outside of the main body 11 through a latch cord slot 15. The pulling direction of the grips 14 can be adjusted by adjusting the position from which the latch cord is pulled out of the latch cord slot 15. During training, the user pulls the grips 14 away from the main body 11, generating tensile resistance in the latch cord, thereby performing the exercise. At this time, the direction of resistance generated by the latch cord is from the position of the grips 14 toward the slider 17.

[0028] In one embodiment, the first rail 16 includes a left portion, the left rail portion 16a, and a right portion, the right rail portion 16b. Similarly, the latch cord slot 15 also has a left portion and a right portion, with the left portion of the latch cord slot 15 extending along the trajectory of the left rail portion 16a, and the right portion of the latch cord slot 15 extending along the trajectory of the right rail portion 16b. A slider 17 is slidably provided on the left rail portion 16a, and similarly, a slider 17 is slidably provided on the right rail portion 16b. Two latch cords each pass through two sliders 17 and are then connected to corresponding grips 14. These two latch cords also pass through the left and right portions of the pull cord groove 15, respectively. The left rail portion 16a has a first end located within the left boundary line 33 and a second end located within the front boundary line 31. On the other hand, the right rail portion 16b has a third end located within the right boundary line 34 and a fourth end located within the front boundary line 31. When the two sliders 17 are in the positions of the first and third ends, respectively, the straight line connecting the pull-out points of the two latch cords is parallel to the front boundary line 31 and passes through the center point of the mounting area 12.

[0029] In one embodiment, a first mounting plate 28 is fixedly installed inside the main body 11 to position the latch cord. A positioning structure for positioning the latch cord is provided on this first mounting plate 28. The positioning structure is as follows: A connecting head 18 is slidably attached to the slider 17, and one end of the connecting head 18 protrudes outside the main body 11 through the latch cord slot 15. After passing through this connecting head 18, the latch cord is connected to the grip 14. A second rail 19 is attached to the lower side of the first mounting plate 28, and the second rail 19 has the same trajectory as the first rail 16. The second rail 19 includes a second rail left part 19a located below the first rail left part 16a, and a second rail right part 19b located below the first rail right part 16b. A mounting block 21 is slidably attached to each of the second rail left part 19a and the second rail right part 19b. One end of the connecting head 18 is inserted into the mounting block 21 and is fitted to the mounting block 21 in a slidable manner. It is necessary to explain that the first mounting plate 28 has a slit through which the connecting head 18 can pass. Lower blocks 20 are provided on the lower sides of the left part 19a and the right part 19b of the second rail, and these lower blocks 20 are fixed to the corresponding mounting block 21. The second rail 19 has a slit that extends along its trajectory, and the connecting head 18 is movable within this slit. A fixing ring 23 is fixed to the connecting head 18, and the outer diameter of this fixing ring 23 is larger than the width of the slit. Furthermore, a spring 22 is positioned between the connecting head 18 and the lower block 20, and both ends of the spring 22 are connected to the lower block 20 and the fixing ring 23, respectively. Multiple pairs of locking grooves 24 are provided at equal intervals along the trajectory of the second rail 19 on the side wall of the slit, and the lower end of each locking groove 24 is through. A portion of the retaining ring 23 fits into one of the pair of locking grooves 24. When the connecting head 18 is pushed in, the spring 22 is compressed, and the retaining ring 23 disengages from the locking grooves 24.In this state, the mounting block 21, the connecting head 18, and the lower block 20 can move along the trajectory of the latch code slot 15. When the push-in of the connecting head 18 is released, the fixing ring 23 is re-engaged in the locking groove 24 by the elastic action of the spring 22, thereby fixing the connecting head 18, the mounting block 21, and the lower block 20 in their predetermined positions.

[0030] In one embodiment, a second mounting plate 30 is fixedly installed inside the main body 11. Two winding plates 27 are rotatably mounted on this second mounting plate 30, and the portions of the two latch cords located in the storage space are wound onto the corresponding winding plates 27. A coil spring 13 is connected between the winding plates 27 and the inner wall of the main body 11. Two servo motors 26 are also fixedly installed inside the main body 11, and the output shafts of these two servo motors 26 are directly connected to the corresponding winding plates 27. When the latch cord is pulled out, the coil spring 13 twists and deforms, and at the same time, the resistance to the latch cord is controlled by the servo motors 26, thereby providing a training effect. When storing the latch cord, the restoring force of the coil spring 13 quickly winds the latch cord.

[0031] Furthermore, two first guide wheels 25 are rotatably mounted on the second mounting plate 30, and one latch cord is guided through the first guide wheel 25 and the corresponding second guide wheel 29, then passes through the connecting head 18 and is connected to the grip 14.

[0032] It needs to be explained that the two first guide wheels 25 are positioned at the centers of the trajectories of the left boundary line 33 and the right boundary line 34, respectively, to prevent the latch cord from becoming loose or detached when adjusting its position.

[0033] Operation process or usage:

[0034] 1. When performing side raise training, the spring 22 is compressed by pushing in the connecting head 18, causing the fixing ring 23 to disengage from the locking groove 24. In this state, the mounting block 21, connecting head 18, and lower block 20 are moved along the trajectory of the latch cord slot 15, adjusting the position of the latch cord to the left and right sides of the mounting area 12. Then, when the pushing in of the connecting head 18 is released, the fixing ring 23 is re-engaged in the locking groove 24 by the elastic action of the spring 22, fixing the connecting head 18, mounting block 21, and lower block 20 in their predetermined positions. This prevents the direction of tension of the latch cord from shifting during training. In this state, side raise training can be performed by pulling the latch cord with the grip 14.

[0035] 2. When performing front raise training, the latch cord is pulled with the grip 14 by adjusting the position of the latch cord to the front of the mounting area 12.
