Detachable illumination device and tent having same

A tent frame comprising:

• a plurality of tent poles;
• a hub connecting two or more tent poles in the plurality of tent poles;
• an illumination device detachably connected to the hub, the illumination device comprising:
• a casing configured to house a battery pack having a plurality of batteries, the casing comprising a first engagement member;
• a light source configured to emit a light when electrically connected to the battery pack;
• a coupler comprising a plate, a second engagement member extended downward from a lower side of the plate, one or more electrically-conductive elastic members coupled with the lower side of the plate, and a third engagement member extended upward from an upper side of the plate;
• and
• a first cover detachably connected to the casing, the first cover comprising a fourth engagement member extended downward from a side of the first cover facing the coupler;
• wherein:
• the second engagement member is movable with respect to the first engagement member in a first direction to facilitate engagement or disengagement of the coupler with or from the casing;
• the second engagement member is immovable with respect to the first engagement member in a second direction to prevent the one or more electrically-conductive elastic members from misaligning with the plurality of batteries;
• and
• when the first cover is connected to the casing, the fourth engagement member is engaged with the third engagement member to push the coupler in the first direction toward the battery pack, thereby pressing the one or more electrically-conductive elastic members against the plurality of batteries to ensure electrical connection.
