Description

  The present invention relates to a battery housing structure for housing batteries of various electric devices such as a digital camera.

  Various electric devices such as a digital camera are provided with a battery chamber for storing a battery, and an insertion port of the battery chamber is normally closed with a battery lid. The battery cover is provided with a battery contact piece for contacting the battery terminal, but it is known that the battery contact piece is formed in a leaf spring shape so as to follow the movement of the battery to prevent instantaneous interruption. ing.

  The battery contact piece has a better followability to the battery as the deflection amount is larger. Therefore, by increasing the deflection amount of the battery contact piece, instantaneous interruption can be prevented. However, if the amount of bending of the battery contact piece is increased, the durability of the contact piece is reduced, and the possibility of being inadvertently touched by a user or the like and being deformed by an external load increases. Therefore, conventionally, it has been difficult to increase the amount of bending of the battery contact piece.

Therefore, as in Patent Document 1, a battery lid provided with a regulating portion that straddles the arm portion of the battery contact piece is known. According to this configuration, when the battery lid is opened, the arm portion is pressed against the regulating portion and the amount of bending of the battery contact piece is suppressed, so that the battery contact piece is touched by the user and the battery contact piece is deformed. Is prevented. Further, when the battery lid is closed, the arm portion is released from the pressing by the restricting portion, so that it can be sufficiently bent and the followability to the battery is improved.

  However, the battery lid in Patent Document 1 is provided with a regulating portion as a separate member from the battery lid, so that the number of parts increases and the assemblability is not good. Accordingly, the present invention provides a battery housing structure provided with a battery contact piece that has good battery followability and is less susceptible to external load, and has a small number of parts and good assemblability. The purpose is to do.

  The battery storage structure according to the present invention includes a battery storage unit that stores a battery by inserting the battery from the insertion port toward the bottom surface, a battery lid that closes the insertion port and faces the end surface of the battery in the closed state. A battery lid supporting plate that is attached to the battery housing so as to be displaced together with the battery lid and that is disposed along the closing surface of the battery lid that closes the insertion port, and the battery lid or the battery. A guide member that is provided on one of the lid support plates and opens and closes the battery lid by sliding the battery lid along the battery lid support plate, and the battery lid or the battery lid support plate from the battery lid A battery contact piece that extends so as to be spaced apart and has a contact portion for contacting the end face. When the battery cover slides along the battery cover support plate, the battery contact piece is pressed against the guide member. The contact part approaches the battery lid And wherein the door.

  When the battery cover slides to open the insertion slot, the battery contact piece is pressed against the guide member, and when the battery cover slides to close the insertion slot, the pressing force against the battery contact piece is weakened, and the tip Is preferably separated from the battery lid. Thereby, when the battery cover is opened, the protruding amount of the battery contact piece with respect to the battery cover is suppressed, so that an external load acting on the battery contact piece can be effectively prevented. Further, since the protruding amount is increased when the battery cover is closed, the contact portion can contact the battery terminal with a sufficient bending force.

  The battery lid support plate is rotatably supported by, for example, the battery housing. In this case, the battery lid rotates in the first circumferential direction together with the battery lid support plate, and then inserted by sliding in the first direction. Close the mouth. In addition, it is preferable that after sliding in the direction opposite to the first direction, the insertion port is opened by rotating in the direction opposite to the first circumferential direction together with the battery lid support plate.

  For example, the battery contact piece includes an arm portion that is fixed to the other of the battery lid or the battery lid support plate and extends away from the battery lid, and the contact portion is provided at the tip of the arm portion. At this time, the arm portion is preferably provided in parallel to the sliding direction in which the battery lid slides, and thereby the arm portion is easily pressed by the guide member.

  For example, the guide members are provided at both ends of the closing surface of the battery lid, the arm portions are provided along the guide members, and the arm portions are pressed by the guide members.

  It is preferable that the contact portion connects the tip portions of both arm portions, and the both arm portions and the contact portion have a substantially U-shape. Thereby, a contact part is formed by simple structure. A contact part may be provided independently at the tip of each arm part. A plurality of arm portions may be arranged in the sliding direction. In this case, when the battery lid slides along the battery lid support plate, each arm portion is pressed by the guide member, and the contact portion approaches the battery lid. Is preferred.

  For example, a part of the guide member is provided so as to cover a part of the battery contact piece (for example, an arm portion), and a part of the guide member covering a part of the battery contact piece presses the battery contact piece. Further, it is preferable that the guide member is provided with a protrusion formed integrally with the guide member, and the battery contact piece is pressed by the protrusion. Also, the guide member is preferably formed integrally with the battery lid. Thus, by forming the guide member integrally with the battery lid or the protrusion, the number of parts of the battery lid can be further reduced, and an easily assembled battery lid can be obtained.

  In the present invention, since the protruding amount of the arm portion with respect to the battery lid can be controlled according to the sliding of the battery lid, it is effectively prevented that an external load acts on the arm portion. Further, since the member for pressing the arm portion is a guide member, it is not necessary to provide a special member for controlling the protruding amount of the arm portion.
