具体的，在本实施例中，以驱动装置为电机进行说明，固定部400即为驱动装置40的定子，弧形支架10两端的壳体内各固定有一个定子，且一个定子固定在外侧壁200的内表面上，另一个定子固定在内侧壁210的内表面上。转动部410即为驱动装置40的转子，风扇30旋转轴310所在位置为一个空腔，转子设置在空腔内且与空腔壁紧贴固定，当旋转轴310插入通孔或凸轴206内时，定子容纳于空腔内且与转子配合形成驱动装置40，通电后，转子转动带动风扇叶轮转动。
上述实施方式中，通过更改风扇的装配方向，使得左右两边风扇可以同向装配，解决了传统挂脖风扇左右风扇镜像设置，两个风扇不能通用且易装配错误的问题。
在其他实施例中，驱动装置40包括电机(图未示)，一个壳体20内的电机固定于外侧壁200上，另一个壳体20内的电机固定于内侧壁210上。风扇30包括叶轮300和套筒(图未示)，套筒套设于电机的轴承上且与轴承固定连接，使得电机带动叶轮300转动。
具体的，本实施例中，电机一端固定于壳体20内表面上，另一端为一个转动轴承，相对应的，风扇30包括叶轮300和设置于叶轮轴心位置的套筒，通过将套筒套设于轴承上以实现叶轮300与轴承的固定连接，当电机工作时，轴承的转动带动叶轮300转动，实现风扇的正常工作。在其他实施例中，风扇包括 叶轮，叶轮轴心位置设置有凹槽，凹槽套设于电机的轴承上且与轴承固定连接，使得电机带动叶轮转动；或，叶轮轴心位置设置有贯穿叶轮的通孔，通孔套设于电机的轴承上且与轴承固定连接，使得电机带动叶轮转动。在其他实施方式中，电机轴承与叶轮的固定方式不做具体限制。
在一个实施例中，如图5所示，壳体20还包括挡板230，挡板230设置于壳体20内，壳体20侧面上还设置有通孔240，侧面为连接于外侧壁200的外表面和内侧壁210的外表面之间的面，挡板230用于将风扇30转动产生的风导向通孔240并通过通孔240导出壳体20。
具体的，壳体20由外侧壁200和内侧壁210扣合形成一端开口的空腔，空腔内设置有风扇30和驱动装置40，开口位置与弧形支架10连接，由于弧形支架10内部中空设置且壳体20较为细长，风扇转动产生的风容易向壳体20开口端流动，不易导出壳体20，达到降温效果。通过在壳体20内设置弧形挡板230，且壳体20侧面设置通孔240，风扇30转动产生的风接触到弧形挡板230后，顺着弧形挡板230流动到通孔240位置，从而导出壳体20，达到出风降温效果。在本实施例中，为达到较佳的导风效果，挡板230为弧形且由设置有通孔的侧面延伸到另一个侧面，从而使得外侧壁200和内侧壁210扣合时，挡板230将风扇30所在空间隔开为独立的空间，且挡板230的延伸方向为空气的流向。在其他可行的实施方式中，挡板230可设置为其他形状，这里不做具体限制。
在一个实施例中，壳体20还包括盖合部250，外侧壁200的外表面设有与风扇30对应的开孔，盖合部250设置于外侧壁210的外表面上且遮盖外侧壁200上的开孔并于开孔之间设有间隙。具体的，在将风扇30安装于壳体20内时，由于壳体20为封闭空间，为保证空气能够进入壳体20内，风扇30转动时能够产生流动的气流，需要在外侧壁210外表面上开设相应的开孔。然而，由于挂脖风扇需要挂在脖颈上使用，为避免头发等其他杂物被吸进壳体20内部，造成风扇30故障，需要对开孔进行遮盖。通过设置盖合部250，可以对外侧壁210上开设的通孔进行遮盖，避免头发等杂物被吸入壳体20内部，造成风扇30故障；同时，盖合部250与外侧壁210的开孔之间留有一定的间隙，保证空气的流通。
在一个实施例中，如图3所示，挂脖风扇还包括软性连接件50，软性连接件50为万向软管，弧形支架10材质为柔性材料，软性连接件50设置于弧形支架10内。其中，软性连接件50为中空设置，通过设置中空软性连接件50，可将导线等连接线设置于所述软性连接件50内，挂脖风扇在使用时，弧形支架10为柔性材料，例如软胶，柔性材料的弧形支架10配合万向软管，可以根据用户需要弯曲变形为任意角度。同时，万向软管保证导线的稳定连接。
在一个实施例中，如图6所示，所述挂脖风扇还包括开关部60，开关部60设置于壳体20上。在本实施例中，通过在外侧壁200上设置与开关部60对应的通孔，从而将开关部60固定于外侧壁200上。通过调节开关部200，可实现挂脖风扇的启动与暂停，同时，还可通过调节开关部60，实现挂脖风扇的风力控制。在实际使用场景中，挂脖风扇多为室外高温环境下使用，在用户短暂进入室内时，可通过开关部60暂时关闭挂脖风扇，达到节约电能的作用，使得挂脖风扇可以有较长的使用时间。同时，在外界温度发生变化时，可通过调节开关部60从而控制挂脖风扇的风力，以达到较佳的降温效果。在其他实施例中，开关部60还可包括其他可行的功能，在此不做过多限定。同样的，开关部60还可设置在挂脖风扇的其他位置，例如弧形支架10，只要是便于用户操作和控制的位置均可。
进一步的，如图6所示，挂脖风扇还包括电池70，电池设置于壳体20内。本实施例中，以将电池70设置在壳体20内为例进行说明。通过在壳体20内设置电池70，在风扇30转动时，电池70可以为驱动装置40提供电能，实现挂脖风扇可随时工作。在其他实施例中，电池70还可以为两块，每个壳体20内设置有一块电池70，分别为驱动装置40提供电能，使得挂脖风扇续航更持久。同理，开关部60也可设置为两个，分别单独控制左右两边的驱动装置40，使得驱动装置40可以单独工作。
上述实施例提供的挂脖风扇，通过将其中一个所述壳体内的所述驱动装置固定于所述外侧壁上，另一个所述壳体内所述驱动装置固定于所述内侧壁上，使得左右两边的风扇装配方向一致，左右两边的风扇可以为相同类型，解决了风扇装配容易出错的问题且提高了风扇的通用性。由于左右两边风扇通用，生 产时降低了生产成本，装配时减少了装配工序，降低错误率。
以上所述实施方式仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
