Battery pack with integral seal member and electronic device including the same
View Patent ↗An electronic device employs a seal member to seal a battery pack to a housing member to prevent contaminants from entering into a battery bay. The electronic device includes a housing member having an exterior surface a portion of which defines a recess, an electronic assembly contained inside the housing member, and an battery pack received in the recess in the exterior surface of the housing member and electrically connected to the electronic assembly inside the housing member. The seal member engages the battery pack and the housing member along an outer circumference of the battery pack and an inner circumference of the recess such that the seal member seals the gap between the outer circumference of the battery pack and the inner circumference of the recess, thereby preventing contaminants from an external environment from entering into an interior of the recess through the gap.

6. The radiographic image receptor of claim 1 wherein the battery pack comprises a protrusion structure along the outer circumference of the battery pack, and the seal member is integrated to the battery pack by attaching the seal member to the protrusion structure.
7. The radiographic image receptor of claim 1 wherein the seal member is integrated to the housing member by an adhesive.
8. The radiographic image receptor of claim 1 wherein the seal member is hollow.
9. The radiographic image receptor of claim 1 ,
wherein the inner circumference of the recess comprises a circumferential first sealing surface and a circumferential second sealing surface that is non-coplanar with the first sealing surface; and
wherein the seal member comprises a circumferential first seal portion configured to engage with the first sealing surface and a circumferential second seal portion configured to engage with the second sealing surface.
10. The radiographic image receptor of claim 1 wherein the seal member is constructed from a material comprising silicone or a thermoplastic elastomer.
11. A battery pack assembly, comprising:
a housing member having an exterior surface;
one or more battery cells inside the housing member; and
a seal member surrounding a periphery of the housing member, wherein the seal member is attached to the exterior surface of the housing member.
12. The battery pack assembly of claim 11 wherein the housing member comprises a protrusion structure along the periphery and the seal member is removably attached to and held in place by the protrusion structure.
13. The battery pack of claim 12 wherein the protrusion structure and the housing member are integrally molded.
14. The battery pack assembly of claim 11 wherein the seal member is attached to the exterior surface of the housing member by an adhesive.
15. The battery pack assembly of claim 11 wherein the seal member is hollow.
16. The battery pack assembly of claim 11 wherein the seal member comprises a circumferential first seal portion configured to engage with a circumferential first sealing surface and a circumferential second seal portion configured to engage with a circumferential second sealing surface that is non-coplanar with the first sealing surface.
17. A battery pack assembly, comprising:
a housing member having an exterior surface;
one or more battery cells inside the housing member; and
a seal member surrounding a periphery of the housing member, wherein the seal member is attached to the exterior surface of the housing member,
wherein the one or more battery cells and the housing member are thin-profiled such that a combination of the battery cells and the housing member has a thickness dimension less than a maximal linear dimension of electrical contacts of the battery pack assembly.
18. The battery pack assembly of claim 11 wherein the seal member is constructed from a material comprising silicone or a thermoplastic elastomer.
19. An electronic device, comprising:
a housing member having an interior surface and an exterior surface, the interior surface defining an interior compartment and a portion of the exterior surface defining a recess;
an electronic assembly contained in the interior compartment;
a battery pack received in the recess and electrically connected to the electronic assembly inside the housing; and
a seal member engaging the battery pack and the housing member along an outer circumference of the battery pack and an inner circumference of the recess such that the seal member seals a gap between the outer circumference of the battery pack and the inner circumference of the recess, wherein the seal member is integrated to the battery pack or the housing member.
20. The electronic device of claim 19 wherein the battery pack comprises a protrusion structure along the outer circumference of the battery pack, and the seal member is integrated to the battery pack by attaching the seal member to the protrusion structure.
