Description

Technical Field

[0001] This utility model relates to the field of fitness bed technology, and in particular to an electrically controlled core bed that can accurately display traction strength. Background Technology

[0002] In existing fitness beds, the common structure is to design a square frame to achieve sliding and fixing of the moving bed. Several tension springs are set between the moving bed and the frame. The trainee moves the moving bed by overcoming these tension springs and adjusts the body position during exercise, thereby achieving the exercise of various muscle groups in the body.

[0003] However, with the increasing prevalence of such training equipment, the force exerted and the corresponding calorie burn when professional fitness trainers apply tension to the core bench are not readily apparent on existing fitness benches. The most direct reason is the inability to calculate the force loss and duration of the tension. Furthermore, the positioning structure of the armrests on existing fitness benches is complex and costly to manufacture. How to reduce the complexity of the positioning components and lower manufacturing costs while ensuring functional stability is a pressing technical challenge.

[0004] To address these shortcomings, the urgent technical problem to be solved is to design an intelligent electronically controlled core bed that can achieve overall bed molding through a relatively simple structure. At the same time, a tension sensor is installed inside the fitness bed, and the tension spring is connected to the tension sensor. The sensor is then connected to a display and control device to achieve real-time monitoring of the tension force, providing trainees with a more accurate display of the applied force. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an intelligent electronically controlled core bed, which uses a tension sensor as an intermediate detection device to detect the tension of the tension spring and display it on the control display device, so that the trainee can intuitively observe the force released during training.

[0006] The electrically controlled core bed described above includes a bed body, inside which a guide rail and a sliding bed are provided, and a display device is also provided on the bed body; the sliding wheels on the sliding bed cooperate with the guide rail;

[0007] The bottom of the sliding bed is equipped with a bed frame tension spring fixing component, and the end of the bed frame is also equipped with a tension sensor. An outer fixing plate is fixed to the tension sensor, and several tension spring fixing holes are provided on the outer fixing plate. Several tension springs are provided between the tension spring fixing holes and the bed frame tension spring fixing component. The tension sensor is connected to a display device through a wire.

[0008] The display device is equipped with an analog-to-digital conversion system, which is used to convert the analog signal from the tension sensor into a digital signal on the display device.

[0009] The bottom of the bed is provided with a tension spring support member, which has several tension spring support grooves. The tension spring is supported and fixed through the tension spring support grooves, so as to prevent the middle of the tension spring from falling and rubbing against the ground when it is not under tension.

[0010] The bed frame has a handrail rotatably fixed to its side via a positioning shaft. The handrail is secured by an angle positioning device, which includes a base plate with an arc-shaped guide groove and several positioning grooves spaced apart. The side plate of the handrail has a positioning point, and a side tension spring is fixed between the positioning point and the positioning shaft. The side plate also has a clearance groove to allow the positioning shaft to move and clear obstacles. A connecting protrusion on the side plate engages with the positioning groove. When the handrail is pulled outwards towards the positioning groove, the handrail overcomes the tension of the side tension spring, causing the connecting protrusion to disengage from the positioning groove. After rotating the handrail to select a suitable angle for the positioning groove, the connecting protrusion is then inserted into the positioning groove, thus adjusting the handrail angle.

[0011] The present invention has the following advantages: a bed tension spring fixing component is provided at the bottom of the sliding bed, and a tension sensor is also provided at the end of the bed. An outer fixing plate is fixed on the tension sensor, and a number of tension spring fixing holes are provided on the outer fixing plate. A number of tension springs are provided between the tension spring fixing holes and the bed tension spring fixing component. The tension sensor is connected to the display device through a wire.

[0012] This invention fixes a tension spring to a tension sensor, transmitting the tension force to a display device when the spring is pulled. This allows the display device to show the force released by the trainee and the corresponding calorie loss during the training. Combined with a control system, it can provide systematic guidance to the trainee, offering the best training plan and improving the user experience and value of the core bed.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0027] Example 1:

[0028] As shown in the attached diagram, an electrically controlled core bed includes a bed body 1, which can be a folding bed body or a non-folding bed body. Casters 11 are provided at the ends of the bed body 1, enabling the overall movement of the electrically controlled core bed in both folded and non-folded states. Since the folding structure of the bed body 1 is a common technology in this field, this embodiment only focuses on the non-folding bed body structure; other folding structures are not described in detail.

[0029] The bed frame 1 is internally equipped with a guide rail 3 and a sliding bed 2. The guide rail 3 is typically located on the inner side of the crossbeam of the bed frame 1. The sliding wheels 24 on the sliding bed 2 cooperate with the guide rail 3 to achieve lateral sliding. Positioning protrusions 31 are also provided at both ends of the guide rail 3 to achieve lateral positioning of the sliding bed 2. The sliding bed 2 includes shoulder pads 21, a headrest 23, and locking buckles 22 on both sides. The locking buckles 22 secure the pull rope, which then passes through the pull rope guide wheel 13 at the top of the upright 12 and is fixed to the pull handle at the end of the pull rope. The trainee can apply force to pull the handle to drive the sliding bed 2 to slide.

[0030] The bed 1 is also equipped with a display device 14; the bottom of the sliding bed 2 is equipped with a bed tension spring fixing component. In this embodiment, the bed tension spring fixing component is a right-angled bed tension spring fixing plate 25, which is locked and fixed to the bottom of the sliding bed 2. More importantly, the end of the bed 1 is also equipped with a tension sensor 40. An outer fixing plate 4 is fixed on the tension sensor 40. A bent flange 41 is provided on the outer fixing plate 4, and several tension spring fixing holes 43 are provided on the flange 41. The two sides of the outer fixing plate 4 are also equipped with clearance holes 44 to avoid the guide rail 3.

[0031] Several tension springs 7 are provided between the tension spring fixing hole 4 and the bed tension spring fixing plate 25; the tension sensor 40 is locked to the outer fixing plate 4 by the sensor fixing bolt 42, and then the tension sensor 40 is connected to the display device 14 by the wire.

[0032] The display device 14 is equipped with an analog-to-digital conversion system. When the user applies force to the pull rope, the pull rope pulls the sliding bed 2. The sliding bed 2 moves laterally, which drives the tension spring 7 to pull the outer fixing plate 4. After the outer fixing plate 4 pulls the tension sensor 40, the signal on the tension sensor 40 is transmitted to the display device 14 through the wire, converting the analog quantity of the tension sensor into a digital quantity on the display device 14.

[0033] The bottom of the bed body 1 is provided with a tension spring support 6, and the tension spring support 6 is provided with a plurality of tension spring support grooves 61. The tension spring 7 is supported and fixed through the tension spring support grooves 61, so as to prevent the middle part of the tension spring 7 from falling and rubbing against the ground when it is not stretched.

[0034] With the above structural design, when this utility model is in use, the tension spring 7 transmits the tension force to the display device, which can display the force released by the trainee and the corresponding calorie loss during the training. At the same time, combined with the control system, it can provide systematic guidance to the trainee, give the trainee the best training plan, and improve the user experience and value of the core bed.

[0035] Example 2:

[0036] Based on Embodiment 1, this utility model further improves the angle adjustment and fixing structure of the handrail 5, such as... Figure 2 , 3 As shown, the side of the bed frame 1 is rotatably fixed with an armrest 5 via a positioning shaft 56. The armrest 5 is fixed by an angle positioning device, which includes a base plate 50 with an arc-shaped guide groove 52 and several positioning grooves 53 spaced apart. The side plate 51 of the armrest 5 has a positioning point 58, and a side tension spring 55 is fixed between the positioning point 58 and the positioning shaft 56. The side plate 51 of the armrest has a clearance groove 57 to allow the positioning shaft 56 to move and clear. The side plate 51 has a plug-in protrusion 54 that engages with the positioning groove 57. When the armrest 5 is pulled outward toward the positioning groove 57, the armrest 5 overcomes the tension of the side tension spring 55, causing the plug-in protrusion 54 to disengage from the positioning groove 57. After rotating the armrest 5 to select a suitable angle for the positioning groove 57, the plug-in protrusion 54 is inserted into the positioning groove, thereby achieving angle adjustment and positioning of the armrest 5.

[0037] The above-mentioned angle positioning device for armrest angle adjustment has a simple structure and is easy to operate. By adopting this technical solution, the complexity of the positioning components is reduced and the manufacturing cost is lowered while ensuring the stability of the armrest angle adjustment function. This not only improves the user experience but also enhances the overall market competitiveness of the core bed, making it an ideal electrically controlled core bed.
