Abstract
(EN)
Embodiments of the present application provide a battery pack, comprising: a housing; a built-in circuit located in the housing; a fragile component located in the housing and connected in series with the built-in circuit, the housing being provided with an opening corresponding to the fragile component; a safety switch located in the housing, on-off of the built-in circuit being controlled by means of on-off of the safety switch; and a cover provided corresponding to the opening, the cover comprising a first state and a second state, wherein in the first state, the cover covers the opening and the safety switch is closed, so that the built-in circuit is connected, and in the second state, the cover is separated from the opening and the safety switch is turned off, so that the built-in circuit is disconnected. In the embodiments, the cover covers the opening, and the battery pack is well sealed, so that the battery pack can be used normally, thereby avoiding a safety accident caused by seal failure during use of the battery pack; when the cover is separated from the opening, the built-in circuit is disconnected, thereby avoiding a safety accident caused by forgetting to disconnect the built-in circuit during maintenance of the fragile component.

Des modes de réalisation de la présente invention concernent un bloc-batterie, comprenant : un boîtier ; un circuit intégré situé dans le boîtier ; un composant fragile situé dans le boîtier et connecté en série avec le circuit intégré, le boîtier comportant une ouverture correspondant au composant fragile ; un interrupteur de sécurité situé dans le boîtier, à l'arrêt du circuit intégré, étant commandé au moyen de la mise hors tension de l'interrupteur de sécurité ; et un couvercle disposé correspondant à l'ouverture, le couvercle comprenant un premier état et un second état, dans le premier état, le couvercle recouvre l'ouverture et l'interrupteur de sécurité est fermé, de telle sorte que le circuit intégré est connecté, et dans le second état, le couvercle est séparé de l'ouverture et l'interrupteur de sécurité est éteint, de telle sorte que le circuit intégré est déconnecté. Dans les modes de réalisation, le couvercle recouvre l'ouverture, et le bloc-batterie est bien scellé, de telle sorte que le bloc-batterie peut être utilisé normalement, ce qui permet d'éviter un accident de sécurité provoqué par une défaillance de scellement pendant l'utilisation du bloc-batterie ; lorsque le couvercle est séparé de l'ouverture, le circuit intégré est déconnecté, ce qui permet d'éviter un accident de sécurité provoqué par oubli de déconnecter le circuit intégré pendant la maintenance du composant fragile.
