Description

一种移动终端散热机构及具有该机构的终端 技术领域 本实用新型涉及一种移动终端， 尤其涉及一种移动终端散热机构以及具有该机构 的终端。 背景技术 随着无线技术的飞速发展， 对终端产品小型化的要求也越来越高， 低成本、 超薄 时尚外观、 高性能的移动终端产品已经成为市场需求的主力。 另一方面， 体积变小和性能提高所带来的负面效应就是难以忍受的发热量， 不仅 影响设备性能的发挥， 也直接影响用户体验。 移动终端传统的散热方法一般是增大壳体内部空间、 贴散热片加强散热等， 使得 热量在壳体表面分布尽可能均匀， 这样通常会使得终端体积变大， 这种设计不适用于 功耗较大且对超薄、 小型化有较高要求的设备。 因此， 有必要设计一种散热装置， 以 便应对终端体积不断变小和发热量不断增加而带来的设计瓶颈。 实用新型内容 本部分提供本实用新型的一般描述，且并不是其全部范围或全部特征的全面公开。 本实用新型的目的是提供一种可以应用于移动终端的散热机构， 可以有效降低终 端设备工作时的表面温度， 适用于功耗较大且对超薄、 小型化有较高要求的设备。 根据本实用新型的一个方面， 提供一种移动终端散热机构， 包括： 设有散热窗的 外壳、 和与所述外壳连接的活动件， 所述散热窗由所述活动件打开或关闭。 在根据本实用新型的实施例中， 所述活动件设有散热孔， 所述散热窗由所述活动 件打开是由活动件移动， 使得所述散热孔与散热窗重叠； 所述散热窗由所述活动件关 闭是由活动件移动， 使得所述散热孔与散热窗错开。 在根据本实用新型的实施例中， 所述散热孔为一个或多个， 所述多个散热孔中的 相邻散热孔之间的距离等于或大于所述散热窗的宽度。 在根据本实用新型的实施例中，所述散热孔的宽度小于或等于所述散热窗的宽度。 在根据本实用新型的实施例中， 所述外壳还包括设置在所述散热窗周围的导轨， 所述活动件沿所述导轨移动打开或关闭所述散热窗。 根据本实用新型的一个方面，提供一种移动终端，包括上述的移动终端散热机构。 在根据本实用新型的实施例中， 所述终端还包括固定在所述外壳一端可旋转的 USB插头， 所述活动件的一端与所述 USB插头连接， 当所述 USB插头旋转到第一位 置时， 所述活动件打开所述散热窗； 当所述 USB插头旋转到第二位置时， 所述活动件 关闭所述散热窗。 在根据本实用新型的实施例中，所述活动件与 USB插头连接的一端为可弯曲的柔 性材料部分， 所述活动件的另一端为硬性材料部分， 所述散热孔开设在所述硬性材料 部分。 在根据本实用新型的实施例中， 所述终端还包括固定在所述外壳上的 USB插头， 所述活动件设有可供用户手动打开和关闭所述散热窗的操作部件。 在根据本实用新型的实施例中， 所述移动终端为移动数据卡。 根据本实用新型实施例提供的终端散热机构是一个可以打开和关闭的散热窗， 开 闭由覆盖其上的活动件实现。这种结构相对于那些增大腔体内部空气层厚度、利用 USB 接口导热、 散热膜横向导热等方法， 成本低且散热效率更高， 效果更好， 可以使终端 设备的表面温度得到显著下降。 同时， 散热窗关闭后终端设备形成一个封闭的状态， 避免灰尘进入。 本实用新型通过直接在终端的外壳设置散热窗， 并通过活动件来打开 和关闭散热窗， 活动件可根据终端尺寸设计， 不需要增大终端设备的尺寸， 适用于功 耗较大且对超薄、 小型化有较高要求的设备。 附图说明 此处所说明的附图用来提供对本实用新型的进一步理解， 构成本申请的一部分， 本实用新型提供的附图仅在于解释说明本实用新型， 附图中显示的各部件尺寸大小不 构成对本实用新型的不当限定。 在附图中： 图 1是符合本实用新型的第一实施例的移动终端散热机构的结构示意图； 图 2是符合本实用新型的第二实施例的移动终端散热机构的结构示意图； 其中， 图 2a是散热窗打开时的示意图， 图 2b是散热窗关闭时的示意图； 图 3是图 1所示的移动终端散热机构的外壳的结构示意图； 图 4是符合本实用新型的第三实施例的移动终端散热机构的结构示意图； 其中， 图 4a是散热窗关闭时的结构示意图， 图 4b是散热窗打开时的结构示意图。 具体实施方式 以下将参考附图并结合实施例来详细说明本实用新型。 需要说明的是， 在不冲突 的情况下， 本申请中的实施例及实施例中的特征可以相互组合。 另外， 应当注意， 为 了清楚的目的， 附图和说明书中省略了与本实用新型无关、 本领域技术人员已知的部 件和处理的表示和描述。 实施例 1 : 请参阅图 1及图 3， 本实施例提供的一种具有散热机构的移动终端， 该移动终端 为移动数据卡， 其包括外壳 1、 活动件 2和 USB插头 3。 所述外壳 1在移动终端设备 内部热源（功放器件）附近设有散热窗 4， 及设置在散热窗 4周围的导轨 5 (请参阅图 3 )。所述活动件 2沿所述导轨 5与外壳 1连接。所述活动件 2设有散热孔 6， 活动件 2 沿导轨 5移动， 当所述散热孔 6与散热窗 4重叠时， 形成散热通道， 可以使移动终端 的表面温度得到显著下降。 活动件 2沿导轨 5移动到另一位置时， 散热孔 6与散热窗 4错开， 由活动件 2遮挡在散热窗 4上， 终端设备形成一个封闭的状态， 避免灰尘进 入。 在本实施例中， 散热孔 6的宽度小于散热窗 4的宽度， 在其他实施例中， 散热孔 6的宽度可以设置成与散热窗 4的宽度相等。
USB插头 3固定在外壳 1的一端， 并可旋转。 活动件 2的一端 7与 USB插头 3 连接， 并被配置为可随 USB插头 3的旋转而弯曲。 活动件 2与 USB插头 3连接的一 端 7为可弯曲的柔性材料部分， 活动件 2的另一端为硬性材料部分， 所述散热孔 6设 置在硬性材料部分。打开 USB插头 3的过程中， 随着活动件 2的软性材料部分由弯曲 慢慢变直， 活动件 2的另一端产生移动， 其运动轨迹受导轨 5的限制。 USB插头 3完 全打开后， 活动件 2的软性材料部分完全变直。 活动件 2的散热孔 6正好与外壳 1上 的散热窗 4重叠， 形成散热通道。 闭合 USB插头 3的过程中， 活动件 2向相反的方向 移动。 USB插头 3完全闭合后， 活动件 2上的散热孔 6与外壳 1上的散热窗 4错开， 活动件 2遮盖在散热窗 4上， 由此形成闭合的效果， 移动终端处于关机存放状态， 同 时起到防尘防水效果。 实施例 2: 请参阅图 2， 本实施例提供的一种具有散热机构的移动终端， 其结构基本与实施 例 1中的结构相同。 关于相同结构的描述， 在本部分不再复述。 在本实施例中， 所述 外壳 11设有两个散热窗 14。 所述活动件 12设有两个散热孔 16。 所述两个散热孔 16 之间的距离大于散热窗 14的宽度。 在其他实施例中， 所述两个散热孔 16之间的距离 可被设置成等于散热窗 14的宽度。 请参阅图 2a， USB插头 13完全打开后， 活动件 12的两个散热孔 16正好与外壳 11上的两个散热窗 14重叠， 形成散热通道。 闭合 USB插头 13的过程中， 活动件 12 向相反的方向移动。请参阅图 2b， USB插头 13完全闭合后， 活动件 12上的两个散热 孔 16与外壳 11上的两个散热窗 14错开， 活动件 12遮盖在两个散热窗 14上。 实施例 3 : 请参阅图 4， 本实施例提供的一种具有散热机构的移动终端， 该移动终端为移动 数据卡，其包括外壳 21、活动件 22和 USB插头 23。在此实施例中，活动件 22和 USB 插头 23没有连接关系， 即活动件 22不随 USB插头 23联动。所述外壳 21在移动终端 设备内部热源（功放器件）附近设有散热窗 24。所述活动件 22被嵌套在外壳 21内部， 嵌套方式可以包括多种方式： 导轨或滑道， 在此不详述。活动件 22上设有可供用户手 动打开和关闭散热窗 24的操作部件 25。 在此实施例中， 活动件 22也可被设置在外壳 21外部。 图 4a所示的是散热窗 24关闭的状态， 活动件 22遮盖在散热窗 24上。 图 4b 所示的散热窗 24打开的状态， 用户通过操作部件 25移动活动件 22， 使得散热窗 24 打开形成散热通道， 从而使移动终端的表面温度得到显著下降。 当然， 在与本实施例相同的情形下， 即活动件不与 USB插头联动的情况下， 其他 实施例中， 外壳的散热窗、 活动件的散热孔还可以分别设置为多个。 用户可以手动操 作活动件， 使得活动件的多个散热孔正好与外壳的散热窗重叠， 形成散热通道。 也可 以通过操作活动件， 使得多个散热孔与散热窗错开， 使得活动件遮盖在散热窗上。 根据本实用新型实施例提供的方案， 是基于热对流原理， 终端工作时其内部产生 的热量使得内部温度升高， 空气压强增大， 产生一个原始的热动力， 所以可以在适当 的位置布置散热机构， 增强热对流通路， 将这些热量更迅速地传导到设备之外的环境 空间。 本实用新型提供的终端散热机构具有可以打开和关闭的散热窗， 开闭由覆盖其 上的活动件实现。 这种结构成本低且散热效率更高， 效果更好， 可以使终端设备的表 面温度得到显著下降。 同时， 散热窗关闭后终端设备形成一个封闭的状态， 避免灰尘 进入。 本实用新型通过直接在终端的外壳设置散热窗， 并通过活动件来打开和关闭散 热窗， 活动件可根据终端尺寸设计， 不需要增大终端设备的尺寸， 适用于功耗较大且 对超薄、 小型化有较高要求的设备。 以上所述仅为本实用新型的优选实施例而已， 并不用于限制本实用新型， 对于本 领域的技术人员来说， 本实用新型可以有各种更改和变化。 凡在本实用新型的精神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本实用新型的保护范围 之内。 工业实用性 如上所述， 本实用新型实施例提供的一种移动终端散热机构以及具有该机构的终 端具有以下有益效果： 相对于现有的增大腔体内部空气层厚度、 利用 USB接口导热、 散热膜横向导热等方法， 成本低且散热效率更高， 效果更好， 可以使终端设备的表面 温度得到显著下降。 同时， 散热窗关闭后终端设备形成一个封闭的状态， 避免灰尘进 入。 本实用新型通过直接在终端的外壳设置散热窗， 并通过活动件来打开和关闭散热 窗， 活动件可根据终端尺寸设计， 不需要增大终端设备的尺寸， 适用于功耗较大且对 超薄、 小型化有较高要求的设备。
