具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
本公开的说明书和权利要求书中的术语“第一”和“第二”等是用来区别不同的对象，而不是用来描述对象的特定顺序。例如，第一开关和第二开关是为了区别不同的开关，而不是为了描述开关的特定顺序。
在本公开实施例中，“示例性的”或者“例如”等词来表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，此外，在本公开实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。
相关技术中电子设备例如笔记本电脑的电源系统采用降压型窄输出电压直流(Narrow VDC Buck-Boost，NVDC)架构，由于NVDC架构一阶电压转换功率过大，从而导致供电线路的功耗过高，进而造成供电线路温度过高的问题。
针对相关技术中存在的技术问题，本公开实施例提供了一种电子设备的供电切换电路。图1为本公开一个或多个实施例提供的一种电子设备的供电切换电路的结构示意图。如图1所示，供电切换电路包括温度检测部件10、控制器11和切换开关电路12，控制器11分别与温度检测部件10和切换开关电路12电连接；温度检测部件10临近预设供电线路13设置并用于检测预设供电线路13的温度以生成温度信号；其中，预设供电线路13为电子设备中预设部件的供电线路；控制器11用于根据温度信号输出切换控制信号，切换开关电路12用于根据切换控制信号控制其自身的开关切换状态，以使电源适配器或电池通过预设供电线路13向预设部件供电。
具体地，控制器11分别与温度检测部件10和切换开关电路12电连接，以实现控制器11与温度检测部件10进行通信，以及控制器11与切换开关电路12进行通信。温度检测部件10例如但不限于温度传感器临近预设供电线路13设置，其中预设供电线路13为电子设备中的供电线路，预设供电线路13与预设部件例如但不限于CPU电连接，进而通过预设供电线路13为预设部件进行供电。在预设供电线路13为预设部件进行供电时，可通过温度检测部件10检测预设供电线路13的温度。其中，预设供电线路13的温度可反应预设供电线路13的功耗，若温度越高可反应预设供电线路13的功率较大即功耗过大，功耗过大影响电子设备例如笔记本电脑的运行性能。
由此，通过设置温度检测部件10，利用温度检测部件10来检测预设供电线路13的温度并生成温度信号，进一步地，温度信号传输至控制器11，控制器11接收该温度信号。其中，温度信号包含了预设供电线路13的温度信息，控制器11根据接收到的温度信号可获取到预设供电线路13的温度。进一步地，控制器11基于预设供电线路13的温度判断预设供电线路13的功耗是否过大，进而生成切换控制信号，并将该切换控制信号传输至切换开关电路12，切换开关电路12根据接收到的切换控制信号，切换预设供电线路13接入电源适配器或电池。
示例性地，当电子设备例如笔记本电脑刚处于运行状态时，温度检测部件10检测到预设供电线路13的温度较低，可默认切换开关电路12控制预设供电线路13接入电源适配器，一方面可通过电源适配器为预设部件进行供电，另一方面还可为电子设备配备的电池进行充电。在电子设备接入电源适配器后，预设部件例如CPU运行重载程序时，通过温度检测部件10检测预设供电线路13的温度，若检测到预设供电线路13的温度过高例如温度超过设定温度阈值，此时可判断预 设供电线路13的功耗过大，控制器11生成切换控制信号，切换开关电路12根据接收到的切换控制信号，切换预设供电线路13接入电池，即由电源适配器切换为电池，以使电池向预设供电线路13提供输入电压，进而实现电池通过预设供电线路13向预设部件进行供电。
其中，预设供电线路为降压变换器(Buck Converter，Buck)电压转换线路，对于BUCK电压转换线路来说，其输入电压和输出电压的差值越大时，预设供电线路13的元器件耗损越大，进而导致预设供电线路13功耗较大以及温度较大；然而当输入电压和输出电压的差值越小时，电压转换效率越高，可降低预设供电线路13的功耗以及温度，有利于提高电子设备的运行性能。
具体地，当电源适配器接入预设供电线路13时，电源适配器的直流输出电压为预设供电线路13的输入电压；当电池接入预设供电线路13时，电池的电压为预设供电线路13的输入电压。然而电池的电压低于电源适配器的输出电压，因此预设供电线路13接入电池时的输入电压小于预设供电线路13接入电源适配器时的输入电压。针对同一预设部件供电，预设供电线路13接入电池时的输出电压和预设供电线路13接入电源适配器时的输出电压是相同的，由此可得到当预设供电线路13接入电源适配器时，其输入电压和输出电压的差值较大，进而导致电压转换线路的元器件损耗较大；当预设供电线路13接入电池时，其输入电压和输出电压的差值较小，可提高电压转换效率，进而降低电压转换线路的元器件损耗；即相同的输出电压值，输入电压越低，电压转换线路的元器件损耗越小，进而有利于降低预设供电线路13的功耗以及温度。
需要说明的是，本公开实施例提供的供电切换电路采用混合电源升压(Hybrid Power BOOST，HPB)架构。示例性地，图2为相关技术中一个或多个实施例提供的一种HPB架构的电路示意图。如图2所示，在电源适配器接入电路后，开关Q1和开关Q2打开，通过电源适配器输出电压为系统供电，同时通过Buck降压线路给电池充电，在电源适配器接入的情况下通常电池不放电，因此电池电压低于电源适配器的输出电压；当断开电源适配器连接时，开关Q3打开，通过电池输出电压为系统供电。即当电源适配器接入时，对于电子设备系统内部所有的供电线路来说，输入电压是电源适配器的直流输出电压；当电源适配器断开时电池供电，系统的输入电压是电池电压；电池电压小于适配器的输出电压。
由此，将混合电源升压(Hybrid Power BOOST，HPB)架构应用 于本公开实施例提供的供电切换电路中，当预设供电线路的接入电压端由电源适配器切换为电池时，有利于降低预设供电线路的输入电压和输出电压之间的差值，从而可降低电压转换线路元器件的耗损，有利于降低预设供电线路的功耗以及温度。
本公开实施例提供的电子设备的供电切换电路通过设置温度检测部件，温度检测部件临近预设供电线路设置并用于检测预设供电线路的温度，并生成温度信号，进一步地，该温度信号传输至控制器，控制器接收该温度信号。其中，温度信号包含了预设供电线路的温度信息，控制器根据接收到的温度信号可获取到预设供电线路的温度。进一步地，控制器基于预设供电线路的温度判断预设供电线路的功耗是否过大，进而生成切换控制信号，并将该切换控制信号传输至切换开关电路，切换开关电路根据接收到的切换控制信号，切换预设供电线路接入电源适配器或电池。由此，在电子设备接入电源适配器运行重载程序时，当检测到预设部件例如CPU对应的预设供电线路的温度过高时，预设供电线路的接入电压端由电源适配器切换为电池，可降低预设供电线路中元器件的耗损，进而降低预设供电线路的功耗以及温度，有利于提高电子设备的运行性能，从而提升了用户的使用体验感。
作为本公开实施例一种可选的实施方式，图3为本公开一个或多个实施例提供的另一种电子设备的供电切换电路的结构示意图。在图1所示结构的基础上，如图3所示，切换开关电路12包括多个切换开关模块14，切换开关模块14与预设供电线路13一一对应设置。图3中示例性地示出了两个切换开关模块14，对应地示出了两个预设供电线路13。
具体地，切换开关电路12包括第一切换开关模块141和第二切换开关模块142，控制器11分别与第一切换开关模块141和第二切换开关模块142电连接。预设供电线路13包括第一预设供电线路131和第二预设供电线路132，第一切换开关模块141与第一预设供电线路131电连接，第二切换开关模块142与第二预设供电线路132电连接，由此控制器11通过控制第一切换开关模块141切换第一预设供电线路131接入电源适配器或电池，以及控制器11通过控制第二切换开关模块142切换第二预设供电线路132接入电源适配器或电池。
其中，针对两个预设供电线路13对应设置两个温度检测部件10，包括第一温度检测部件101和第二温度检测部件102，第一温度检测部件101用于检测第一预设供电线路131的温度，第二温度检测部件102用于检测第二预设供电线路132的温度，即预设供电线路13、温度检 测部件10和第一切换开关模块14是一一对应设置的。
需要说明的是，还可设置切换开关电路12包括三个或更多个切换开关模块，相应地设置三个或更多个预设供电线路13和温度检测部件10。
作为本公开实施例一种可选的实施方式，图4为本公开一个或多个实施例提供的又一种电子设备的供电切换电路的结构示意图。在图1所示结构的基础上，如图4所示，切换开关电路12包括一个切换开关模块14，切换开关模块14与所有的预设供电线路13对应设置，图4示例性地示出了两个预设供电线路13。
具体地，设置切换开关电路12包括一个切换开关模块14，切换开关模块14分别与第一预设供电线路131和第二预设供电线路132电连接，控制器11与切换开关模块14电连接，由此通过控制器11控制一个切换开关模块14切换电源适配器或电池接入第一预设供电线路131，以及切换电源适配器或电池接入第二预设供电线路132。其中，针对两个预设供电线路13对应设置两个温度检测部件10，包括第一温度检测部件101和第二温度检测部件102，第一温度检测部件101用于检测第一预设供电线路131的温度，第二温度检测部件102用于检测第二预设供电线路132的温度。
需要说明的是，图4与图3的区别在于：图3针对每一个预设供电线路13均设置对应的切换开关模块14，即预设供电线路13与切换开关模块14一一对应设置；而图4针对所有的预设供电线路13设置一个切换开关模块14，可以理解为图4将图3中的多个切换开关模块集成设置为一个切换开关模块，从而有利于简化路线，进而降低设计成本。
由此，结合图3和图4，针对预设供电线路13一一对应设置温度检测部件10，其中，每个预设供电线路13均作为向对应的预设部件供电的线路。当电子设备例如笔记本电脑运行不同程序时，需要启动不同的预设部件例如CPU和DGPU等，且不同预设部件的预设供电线路13的负载是不一样的。示例性地，有的程序运行时需要调用CPU进行大量计算，对应CPU的预设供电线路13负载就会很高，而不需要调用DGPU进行图像处理，则对应DGPU的供电线路负载就会很低；有的程序运行时需要调用DGPU进行图像处理，对应DGPU的供电线路负载就会很高，而不需要调调用CPU进行大量计算，则对应CPU的供电线路负载就会很低。由此，用户可以在电子设备处于不同使用情景下，检测每组预设供电线路的实时温度，有选择性的调整不同预设 部件的预设供电线路的输入电压例如电池电压，有利于优化电子设备的预设供电线路的温度，安全可靠。
另外，由于预设供电线路的输入电压切换为电池电压后，电池的辅助放电，让电源适配器节省下的功耗能够供给其它预设部件使用，有利于提升电子设备整机系统的性能。例如将对应CPU供电线路的输入电压切换为电池电压后，原来电源适配器供给CPU的能耗可节省供给DGPU使用，可提升DGPU的运算能力。

具体地，可设置切换开关模块14包括第一开关15和第二开关16。其中，第一开关15的第一端连接电源适配器，即连接输入电压VIN1，第一开关15的第二端连接预设供电线路13，第一开关15的控制端接入第一切换控制信号T1；第二开关16的第一端连接电池Battery，即连接输入电压VIN2，第二开关16的第二端连接预设供电线路13，第二开关16的控制端接入第二切换控制信号T2。
具体地，当控制器11生成第一切换控制信号T1，对应地第一开关15的控制端接入第一切换控制信号T1，当根据温度检测结果控制第一开关15闭合时，从而导通电源适配器与预设供电线路13的电连接线路，实现预设供电线路13接入电源适配器；当控制器11生成第二切换控制信号T2时，对应地第二开关16的控制端接入第二切换控制信号T2，当根据温度检测结果控制第二开关16闭合时，从而导通电池与预设供电线路13的电连接线路，实现预设供电线路13接入电池。
其中，第一开关15和第二开关16可设置为N沟道金属氧化物半导体(N channel Metal Oxide Semiconductor，NMOS)管，或者P沟道金属氧化物半导体(P channel Metal Oxide Semiconductor，PMOS)管。
作为本公开实施例一种可选的实施方式，图6为本公开一个或多个实施例提供的又一种电子设备的供电切换电路的结构示意图。如图6所示，控制器11包括第一切换端A和第二切换端B，第一切换端A通过第一导线17与切换开关电路12直连，第二切换端B通过第二导线 18与切换开关电路12直连。
具体地，控制器11包括第一切换端A，第一切换端A通过第一导线17与切换开关电路12中第一开关15的控制端电连接，第一切换端A控制输出第一切换控制信号T1，第一切换控制信号T1通过第一导线传输至第一开关15的控制端，控制第一开关15闭合或断开，以控制对应的预设供电线路13是否接入电源适配器。控制器11还包括第二切换端B，第二切换端B通过第二导线18与切换开关电路12中第二开关16的控制端电连接，第二切换端B控制输出第二切换控制信号T2，第二切换控制信号T2通过第二导线18传输至第二开关16的控制端，控制第二开关16闭合或断开，以控制对应的预设供电线路13是否接入电池。

具体地，在第一切换端A和第一开关15的控制端的连接线路中设置第一控制开关19，通过控制第一控制开关19闭合，导通第一切换端A和第一开关15的控制端的连接线路，将第一切换端A输出的第一切换控制信号T1传输至第一开关15的控制端，控制第一开关15闭合或断开，进而实现预设供电线路13是否接入电源适配器；在第二切换端B和第二开关16的控制端的连接线路中设置第二控制开关20，通过控制第二控制开关20闭合，导通第二切换端B和第二开关16的控制端的连接线路，将第二切换端B控制输出的第二切换控制信号T2传输至第二开关16的控制端，控制第二开关16闭合或断开，进而实现预设供电线路13是否接入电池。
以图7所示结构为例，以预设供电线路13为CPU(预设部件)供电进行示例性说明。当预设供电线路温度较高时，控制器11发出第二 切换控制信号T2，先将第一控制开关19断开，第一开关15关闭，电源适配器的电压被切断，此时切换瞬间电池通过第二开关16的寄生二极管顺向导通供电，保证电压的无缝切换，确保不会因为预设供电线路的输入电压切换而导致CPU断电，而后控制第二控制开关20闭合，第二开关16导通，CPU供电线路的输入电压正式由电源适配器的输入电压切换为电池电压。当电子设备结束运行重载程序或者电池电量剩余不足时，可随时将预设供电线路13的输入电压切换回电源适配器的输入电压。控制器11发出第一切换控制信号T1，先将第二控制开关20断开，此时电池电压通过第二开关16的寄生二极管顺向导通供电，而后经将第一控制开关19闭合，第一开关15导通，第二开关16的寄生二极管反向截至，完成无缝切换，CPU供电线路的输入电压由电池电压切换为电源适配器的输入电压。

S101、获取根据预设供电线路的温度生成的温度信号；
S102、根据温度信号控制切换开关电路的开关切换状态，以使电源适配器或电池通过预设供电线路向预设部件供电。
具体地，参照图1，临近预设供电线路13设置温度检测部件10，利用温度检测部件10来检测预设供电线路的温度并生成温度信号，进一步地，该温度信号传输至控制器11，控制器11接收该温度信号。其中，温度信号包含了预设供电线路13的温度信息，控制器11可获取到预设供电线路13的温度。进一步地，控制器11基于获取到的预设供电线路13的温度进而生成对应的切换控制信号，并将该切换控制信号传输至切换开关电路12，切换开关电路12根据接收到的切换控制信号，切换预设供电线路13接入电源适配器提供或电池，以使电源适配器或电池向预设供电线路13提供输入电压，进而实现预设供电线路13向预设部件供电。
本公开实施例提供的电子设备的供电切换方法，通过获取根据预设供电线路的温度生成的温度信号，进一步地，该温度信号传输至控制器，控制器接收该温度信号。其中，温度信号包含了预设供电线路的温度信息，控制器根据接收到的温度信号可获取到预设供电线路的温度。进一步地，控制器基于预设供电线路的温度判断预设供电线路的功耗是否过大，进而生成切换控制信号，并将该切换控制信号传输至切换开关电路，切换开关电路根据接收到的切换控制信号，切换预设供电线路接入电源适配器或电池。由此，在电子设备接入电源适配器运行重载程序时，当检测到预设部件例如CPU对应的预设供电线路的温度过高时，预设供电线路的接入电压端由电源适配器切换为电池，可降低预设供电线路中元器件的耗损，进而降低预设供电线路的功耗 以及温度，有利于提高电子设备的运行性能，从而提升了用户的使用体验感。
作为本公开实施例一种可选的实施方式，根据温度信号控制切换开关电路的开关切换状态，包括：
当预设供电线路的温度大于预设温度时，控制切换开关电路的开关切换状态，以使电池通过预设供电线路向预设部件供电，其中温度信号包含预设供电线路的温度信息。
具体地，继续参照图1，基于控制器11获取到的温度信号，可获取到预设供电线路13的温度，当判断预设供电线路13的温度大于预设温度时，可判断预设供电线路13的功耗过大，功耗过大可影响电子设备的运行性能，此时控制器11可生成切换控制信号，并将该切换控制信号传输至切换开关电路12，切换开关电路12根据接收到的切换控制信号，切换预设供电线路13接入电池，以使电池向预设供电线路13提供输入电压，实现预设供电线路13向预设部件供电的同时，可提高预设供电线路13的电压转换效率，进而降低预设供电线路13的功耗以及温度，有利于提高电子设备的运行性能。
需要说明的是，在电子设备处于运行状态初期，预设供电线路13的温度较低，可默认切换开关电路12切换预设供电线路13接入电源适配器，在电源适配器为电子设备的预设部件供电的同时，还可为电子设备中配备的电池充电。在电子接入电源适配器运行重载程序时，当检测到对应于预设部件例如CPU的预设供电线路13的温度过高时，此时可切换电池为对应的预设部件供电，有利于提高预设供电线路13的电压转换效率，进而可降低预设供电线路13的功耗，以实现降低预设供电线路13的温度，提高电子设备的运行性能。

当判断剩余电量小于预设电量时，控制切换开关电路的开关切换状态，以使电源适配器通过预设供电线路向预设部件供电。
具体地，继续参照图1，当电池接入预设供电线路13向预设部件供电时，控制器11检测并获取电池的剩余电量，控制器11根据电池的剩余电量判断是否切换电源适配器接入预设供电线路向预设部件供电。具体地，当检测到电池的剩余电量过低时，例如电池的剩余电量小于预设电量，为了保证电子设备中的预设部件例如CPU继续运行程序，此时控制器11生成切换控制信号并传输至切换开关电路12，进一 步地，切换开关电路12切换电源适配器接入预设供电线路向预设部件供电。
由此，本公开实施例提供的电子设备的供电切换方法，在电子设备例如笔记本电脑接入电源适配器运行重载程序时，能提高部分预设部件对应的预设供电线路的电压转换效率，从而降低其供电线路的温度。由此，用电池取代了电源适配器作为输入电压对对应的预设部件供电，相当于电池在辅助电源适配器给电子设备的系统供电，从而优化了电子设备的运行性能，改善了因部分供电线路温度过高导致电子设备的运行性能降低，让使用者感觉不适的问题。
