具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
一种测温结构，如图1-图6所示，包括支架1、温度传感器2和被测物5，所述温度传感器2设置在所述支架1上，并与至少部分所述被测物5接触；所述支架1上还设置至少一个压力保持机构4，所述压力保持机构4施加力到所述被测物5上，使所述被测物5夹紧在所述温度传感器2和所述压力保持机构4之间。
目前的测温结构只能使被测物5和温度传感器2相接触，当环境发生振动时，被测物5和温度传感器2会发生偏移，无法紧密接触，温度传感器2测量的温度不准确，控制系统根据不准确的温度信息，会执行错误的控温措施，很容易引发被测物5附近温度过高导致烧毁。
温度传感器2和压力保持机构4设置在支架1上，且两者之间形成容纳被测物5的区域，当被测物5插入该区域后，压力保持机构4受到挤压力，它同时也向被测物5提供夹紧力，使其夹紧在压力保持机构4和温度传感器2之间。此时，温度传感器2与至少部分被测物5接触以测量被测物5的温度。压力保持机构4可以根据需要设置一个或多个，多个压力保持机构4能够提供更强的挤压力使被测物5和温度传感器2贴合的更紧密来获得更接近真实温度值的测量值。
在一些实施例中，所述压力保持机构4与所述温度传感器2分别处于所述被测物5的两侧。
压力保持机构4能够向被测物5提供挤压力，使被测物5被夹紧在压力保持机构4和温度传感器2之间。以此来保证被测物5和温度传感器2亲密贴合，能够使温度传感器2监测到的被测物5温度更接近真实值。合理的夹紧力既能保证被测物5和温度传感器2的贴紧度又能防止被测物5安装困难。
在一些实施例中，所述压力保持机构4向所述被测物5施加的力值为0.05N-195N。
为了测试压力保持机构4提供的压力对温度传感器2准确度的影响，发明人做了相关测试。发明人选用相同的被测物5，相同的温度传感器2设置在相同的支架1上。选用测试传感器设置在被被测物5上且与被测物5紧密贴合，选用不同的压力保持机构4，不同的压力保持机构4提供的复位力也不相同，温度传感器2与被测物5之间的压力也不相同，当被测物5工作后，被被测物5温度开始升高，经过20分钟，温度趋于稳定，这时同时记录测试传感器所采集的温度值y和不同的压力保持机构4连接的温度传感器2所采集的温度值x，计算x/y的比值，大于99.95％为理想状态。结果如表1所示。
表1：压力保持机构提供的压力对温度传感器准确度的影响
从表1可知，当压力保持机构4对被测物5施加的力小于0.05N后，温度传感器2所采集的温度值与测试传感器所采集的温度值相差过大，其比值小于理想值99.95％，所以发明人选用的压力保持机构4对被测物5施加力大于等于0.05N，当压力保持机构4对被测物5施加的力大于195N后，温度传感器2测量的温度已经非常接近测试传感器测量的温度，再施加更大的力对比值已经没有影响，而且提供更大力的压力保持机构4会导致被测物5的安装更加困难，因此发明人选用压力保持机构4提供的压力为0.05N-195N。
在一些实施例中，所述压力保持机构4在不同环境温度下，向所述被测物5施加不同的力值。在大多数情况下，被测物5在使用时环境温度会发生很大变化，被测物5和温度传感器2之间的间隙会随着环境温度的增大而增大，导致温度传感器2不能够准确的测量被测物5的实际温度，这就会使温度传感器2测量的温度不准确，控制系统根据不准确的温度信息，会执行错误的控温措施，引发相关装置温度过高导致烧 毁。因此当环境温度增大时，压力保持机构4的体积也随之增大以提供更大的压力，使被测物5和温度传感器2紧密贴合，来保证温度传感器2能够准确的测量被测物5的实际温度。当环境温度减小时，压力保持机构4的体积也减小，但是同样的被测物5和温度传感器2之间的间隙也会减小，使被测物5和温度传感器2紧密贴合。
压力保持机构4随环境温度变化而产生形变的特性，可以使用膨胀率较大的材料来制作压力保持机构4，并且这种膨胀率较大的材料能够随着环境温度变化而发生整体体积变化。也可以采用不同膨胀率材料结合制成压力保持机构4，当环境温度变化时，不同膨胀率材料结合的压力保持机构4会发生弯曲或扭曲，从而产生更大的压力施加给被测物5，使被测物5和温度传感器2紧密贴合。
在一些实施例中，所述压力保持机构4为弹性片，如图2所示，所述弹性片包括相互连接的固定部41和弹性部42，所述固定部41与所述支架1固定连接，所述弹性部42可变形产生弹性力。当被测物5安装后，弹性部42发生变形，从而产生持续的挤压力给被测物5，使被测物5能够与温度传感器2紧密贴合。
进一步的，支架1上设置有弹片座43，固定部41设置在所述弹片座43上。如图3所示，固定部41可以焊接在弹片座43上，也可以采用螺接或卡接的方式与弹片座43连接，便于在弹性部42的弹性不足时，对弹性片进行更换。
在一些实施例中，所述固定部41与所述弹性部42的延伸方向呈设定的角度，所述固定部41与所述弹性部42的延伸方向的角度变化产生弹性力。如图4所示，弹性部42与被测物5相互挤压，是弹性部42与固定部41的夹角发生变化，弹性部42就会产生趋于复位的弹力从而使被测物5与温度传感器2贴合。进一步的，弹性部42与固定部41可以形成V形或U型，通过夹角发生变化产生弹性力。
在一些实施例中，所述压力保持机构4包括支撑部和弹性体，所述支撑部固定在所述支架上，所述弹性体设置在所述支撑部相对于所述被测物5的一个侧面上。弹性体自身会在受挤压后产生弹性使被测物5与温度传感器2贴合。
进一步的，所述弹性体为弹性橡胶或弹性软胶或压缩弹簧。弹性橡胶、弹性软胶和压缩弹簧属于传统材料，易于选择和加工。
在一些实施例中，所述支架1具有凹槽11，如图2所示，所述温度传感器2设置在所述凹槽11内。凹槽11能够更好的将温度传感器2固定，防止温度传感器2在晃动中脱离工作位置。凹槽11在温度传感器2放入的一侧的端面，在凹槽11的内边 棱角处，设置倒角或倒圆，能够使温度传感器2在导向的作用下，更加顺利的插入凹槽11中，凹槽11在温度传感器2放入的一侧的端面上还设置具有弹性的阻挡钩，在温度传感器2放入凹槽11中时，可以将阻挡钩移动到不影响温度传感器2放入的位置，当温度传感器2放入后，阻挡钩能够阻挡住温度传感器2的端面，使温度传感器2不能从凹槽11中脱离。如果需要使温度传感器2从凹槽11中脱离，则需要将阻挡钩变形移动到不影响温度传感器2拔出的位置。
在一些实施例中，所述凹槽11朝向所述被测物5一侧设置开口，所述温度传感器2具有测温面，所述测温面与所述开口外侧面平齐或凸出于所述开口外侧面。如图4所示，测温面突出于开口，或者与开口平齐，能够更好的与被测物5贴合，使温度传感器2测量的温度值更接近真实值。
在一些实施例中，当所述测温面凸出于所述开口外侧面时，所述凹槽11在所述开口相对一侧面上设置弹性元件，所述弹性元件施加力到所述温度传感器2上。这样弹性元件与压力保持机构4分别从被测物5的两侧施加弹性力，弹性元件的力是直接施加给温度传感器2的，再施加给被测物5，这样双侧施加弹性力，能够使被测物5和温度传感器2的贴合程度进一步提升。
所述弹性元件向所述温度传感器2施加的力值为0.05N-195N。
为了测试弹性元件提供的压力对温度传感器2准确度的影响，发明人做了相关测试。发明人选用相同的被测物5，相同的温度传感器2设置在相同的支架1上。选用测试传感器设置在被被测物5上且与被测物5紧密贴合，选用不同的弹性元件，不同的弹性元件提供的复位力也不相同，温度传感器2与被测物5之间的压力也不相同，当被测物5工作后，被被测物5温度开始升高，经过20分钟，温度趋于稳定，这时同时记录测试传感器所采集的温度值y和不同的弹性元件连接的温度传感器2所采集的温度值x，计算x/y的比值，大于99.95％为理想状态。结果如表2所示。
表2：弹性元件提供的压力对温度传感器2准确度的影响
从表2可知，当弹性元件对被测物5施加的力小于0.05N后，温度传感器2所采集的温度值与测试传感器所采集的温度值相差过大，其比值小于理想值99.95％，所以发明人选用的弹性元件对被测物5施加力大于等于0.05N，当弹性元件对被测物5施加的力大于195N后，温度传感器2测量的温度已经非常接近测试传感器测量的温度，再施加更大的力对比值已经没有影响，而且提供更大力的弹性元件会导致被测物5的安装更加困难，因此发明人选用弹性元件提供的压力为0.05N-195N。
进一步的，所述弹性元件为弹性橡胶或弹性软胶或压缩弹簧。弹性橡胶、弹性软胶和压缩弹簧属于传统材料，易于选择和加工。
更进一步的，所述压缩弹簧与所述温度传感器2电性连接，用于传输所述温度传感器2的数据。也就是说压缩弹簧本身具有输出数据的功能。压缩弹簧一端与温度传感器2电性连接，另一端和数据线或电路板连接，再连接温度采集装置，这样就避免了从温度传感器2上单独设置数据线所造成的充电设备内部布局过于复杂的问题。温度传感器采集到被测物5的温度后通过能够输出数据的弹性部件最终发送给温度采集装置。
在一些实施例中，所述支架1上还包括卡接环31，所述卡接环31上设置的过口32，所述过口32的宽度小于所述卡接环31的直径。卡接环31用于将支架1卡接在需要的地方，从而使本申请的测温结构可以方便的应用于各种场合。
所述支架1上还包括固定柱6，所述固定柱6包括柱体61和帽体62，所述柱体61一端与所述支架1连接，另一端与所述帽体62连接，所述帽体62的径向尺寸大于所述柱体61的径向尺寸。固定住6用于对支架1的固定，柱体61能够伸入装配位置的装配孔，而帽体62能够防止柱体61从装配孔脱出。
本申请还公开了一种端子固定座，包括如上所述的一种测温结构和固定板7，所述固定板7设置卡接凸起71和固定孔72，所述卡接凸起71与所述卡接环31卡接，所述固定柱6穿过所述固定孔72并固定连接，被测物5为端子。如图5所示，安装时，可以先将固定柱6与固定孔72连接，具体实施时，可以采用帽体62螺接在柱体61的形式，在柱体61穿过固定孔72后，再将帽体62螺接在柱体61上，固定柱6从固定孔72中退回。安装好固定柱6，再将卡接环31与卡接凸起71卡接，从而使支架1固定在固定板7上。在另外一些时候，也可以先将卡接环31与卡接凸起71卡接，再将固定柱6固定在固定板7上。
在一些实施例中，卡接凸起71包括固定架和设置在所述固定架上的固定轴，所述固定架设置在所述固定板7上，所述固定轴通过所述过口32卡接在所述卡接环31内，所述过口32的宽度小于等于所述固定轴的直径。卡接环31与固定轴卡接，从而将支架1设置在固定板7上，安装时，需用力将固定轴推入卡接环31，过口32小于固定轴的直径，所以能够防止卡接环31和固定轴轻易分开。
在一些实施例中，所述固定孔72包括相互连通的定位槽74和安装孔73，所述安装孔73直径大于等于所述帽体62的直径，所述定位槽74宽度大于等于所述柱体61的直径但小于所述帽体62直径，所述帽体62底部到所述固定板7上表面的距离，大于等于所述固定板7的厚度。如图6所示，安装时，将固定柱6插入安装孔73，再横向推入定位槽74，帽体62的直径大于定位槽74的宽度且小于安装孔73的直径，保证它能过穿过安装孔73，而不通过定位槽74，从而起到限制固定柱6从定位槽74脱出的目的。
本申请同时提供了一种充电装置，包括如上所述的一种测温结构和/或一种端子固定座。
虽然已经通过例子对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
