Description

一种大坡度跑步的健身中心
本案有请求优先权，优先权号2021100848646、优先权日2021年1月22日。
技术领域
本发明涉及健身器材技术领域，特别涉及一种大坡度跑步的健身中心。
背景技术
健身中心，是一种新型的健身器材理念，该理念主导的是将多种健身器材设计为一体、打造出一种全型的家庭式健身器材集成中心。
本案涉及了包括跑步机在内的一种健身中心，众所周知，框架和跑台是跑步机的主要组成部分，现在几乎所有的跑台都具有坡度调节功能，给用户跑步增加了新的乐趣，但是有很多的跑步爱好者反映，跑步带随着跑台的坡度提高常会出现“失速”现象，因为跑台的角度逐渐增大，跑步带受重力作用，静摩擦力减小，跑步带的加速度增大，但此时跑步机并没有稳定跑步速度，所以此时的跑步带速度超出了预设速度。这样一来就很有可能使用户在不知道速度增加的情况下，没有相应提高自身的跑步速度，而由于动力不足导致失速，从而引发安全隐患。
此外，健身中心通常都会配置有扶手，方便使用者把手搭放在扶手上，根据使用者的身高不同以及器械搬运的需要，目前市场已有一些扶手能够转动收叠，但往往转动后必须通过插销等固定装置固定角度，缺少自动固定的功能。
本案意将解决上述两种问题，并研发出一种全新使用方式的健身中心。

当采用电动式驱动时，所述驱动装置3可以为电机与减速组件或传动组件的组合，或者所述驱动装置3为能够输出高扭力的电机，而当需要手动驱动时，所述驱动装置3可以为转动手轮。
以图4所示的所述驱动装置3为电机与传动组件的组合为例，所述驱动装置3设置在所述扶手1的内部，所述驱动装置3包括驱动电机31、齿轮组32和输出轴33，所述驱动电机31的电机轴连接齿轮组32，齿轮组32上设置所述输出轴33，所述驱动电机31通过齿轮组32带动输出轴33转动。
本发明抱紧装置的工作原理为，第一连接凸台413与所述框架2上的安装盒21焊接，第二连接凸台464与所述扶手1焊接，扶手1内的驱动装置3驱动输出轴33转动，带动偏心挡圈43旋转，偏心挡圈43通过其以对偏心挡块431与偏心块42的第一偏心块421和第二偏心块422上的一对第一挡槽4212和一对第二挡槽4222相配合，带动偏心块42的第一偏心块421和第二偏心块422转动，因偏心块42的第一偏心块421和第二偏心块422上的第一偏心孔4213、第二偏心孔4223相对于第一偏心块421和第二偏心块422是偏心的，因此能推动内齿圈44作偏心运动，使活动齿板46的角度发生变化，从而达到控制和调节扶手1角度的作用，只要保证输出轴33静止，扶手1就能在任一角度实现抱紧。
如图2所示，为了保证扶手1之间的同步性，两个所述扶手1之间连接一转轴5。
为便于参阅，图8和图10分别为图7和图9中的局部放大图。
本案所述电机10优先选择无刷电机10。
所述跑台9的前端设置所述前滚筒7，所述跑台9的后端设置所述后滚筒8，所述跑步带6套设在所述跑台9的外部，并且跑步带6的两端分别绕接所述前滚筒7和后滚筒8，所述无刷电机10的输出端连接所述前滚筒7，所述无刷电机10可通过和所述前滚筒7之间设置传动机构来省力驱动前滚筒7转动，传动机构可以采用蜗轮蜗杆机构，也可以采用齿轮传动，本案不限限制，本实施例以同步带传动机构为例进行描述，所述传动机构包括同步带14和带轮15，所述前滚筒7设有中心轴，所述带轮15与所述前滚筒7的中心轴固定，所述同步带14的两端分别绕接所述无刷电机10的输出端和所述带轮15，工作时，前滚筒7作为主动轮，后滚筒8作为从动轮，首先无刷电机10启动，通过同步带14带动带轮15转动，前滚筒7转动，从而跑步带6就可以跑起来了。
所述无刷电机控制板11分别连接所述无刷电机10、刹车电阻12和坡度传感器13。
坡度传感器13会自动记录跑台9坡度升降时的坡度数据，然后把坡度数据发送给无刷电机控制板11，无刷电机控制板11根据无刷电机10需要消耗的转速变化，调整无 刷电机输出到刹车电阻上的功耗，其跑台9的坡度在未上升时，假设恒定速度为V，当坡度上升时，增加无刷电机10输出到刹车电阻12的功耗，前滚筒7的转速降低，跑步带6的速度减慢，此时的速度为V-，比恒定速度V来得慢，但加上失速带来的加速度，使得实际上用户的速度与恒定速度保持一致，当坡度下降时，减少无刷电机10输出到刹车电阻12的功耗，前滚筒7的转速增大，跑步带6的速度加快，此时的速度为V，回到未上升时的恒定速度，从而达到跑步带6在高低坡度都能保持恒定速度。
健身中心的升降机构可以是各种各样的，本发明采用了一种既可用于收叠，又可用于升降的第一升降机构，所述第一升降机构安装在框架上，所述跑台9前部连接第一升降机构，第一升降机构带动跑台9前部进行升降，实现跑台9坡度的升降。所述第一升降机构包括两根跑台丝杠16、第一减速电机以及配合在跑台丝杠16上的跑台螺母17，图11所示的是单边丝杠上的第一升降机构的结构示意图，所述框架2两侧分别竖直安装跑台丝杠16，两根跑台丝杠16连接第一减速电机，所述跑台9前部两侧设有跑台凸轴18，所述跑台螺母17上设有供跑台凸轴18放置的第一凹槽，跑台螺母17配合在跑台丝杠16上，带动跑台9前部沿跑台丝杠16作升降运动。所述坡度传感器13可设计在升降机构的第一减速电机上，以实时监测升降机构带动跑台的升降情况，即坡度。
由于本发明的跑台9在坡度增加的时候，跑步带6能够稍微刹车降速，加上扶手1在任意角度都能抱紧，健身用户在使用本发明时，可以将跑台9坡度调高形成“山坡”、再将扶手1转动成上翘的角度形成“登山杖”，从而健身用户能够抓住转动抱紧的“登山杖”、脚踩“山坡”，犹如在进行类似登岩的运动方式，比一般的跑步更具创新性，满足无法外出登山的需求。
以上所述仅为本发明的较佳实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
