Abstract

(57) [Summary] [Purpose] In the structure of the battery box for portable electronic equipment products, the hook part is damaged even if the battery cover is tightened at a position where the battery cover hook part and the case hook part deviate from the normal fitting state. Try not to. According to the present invention, the case hook 21 is provided with a spring property, and the case hook 21 and the tip of the lid hook portion are provided with a rounded shape. When a force is applied in the direction of the arrow at a position deviated from the normal fitting state and the lid body 1 is tightened, the case hook 21 bends like a case hook 21 'with the portion A as a fulcrum, and when further force is applied, the lid hook 11 is released. The lid 1 is fixed to the case 2 by being locked inside the case hook 21.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lid structure utilizing elastic deformation of a component storage portion of a portable electronic device product.

[0002]

[Prior Art]

 In the conventional lid structure utilizing elastic deformation, as shown in FIG. 4, the lid 1 is parallel to the case 2 and a force is applied as shown by an arrow to move the case locking portion 5 to the tip of the lid locking portion 6. Then, as shown in Fig. 3, it was fixed by the locking part in the lateral direction, and fixed by the case hook 3 and the lid hook 4 in the vertical direction.

[0003]

[Problems to be solved by the device]

 In the conventional lid structure utilizing elastic deformation, when the lid body 1 is assembled, the lid body 1 is parallel to the case 2 and the lid hook 4 is inserted into the case hook 3 as shown in FIG. I had to apply force. If you are unfamiliar with parts replacement or if you are in a hurry, etc., apply force in the direction of the arrow with the lid hook 4 on the case hook 3 displaced from the normal fitting state as shown in FIG. If added, the case hook 3 or the lid hook 4 would be damaged.

[0004]

[Means for Solving the Problems]

 In this device, in order to prevent the hook from being damaged even if a force is applied in the direction of the arrow when the lid hook 11 is located on the case hook 21, an inverted L-shape is formed from the side wall of the case along the side surface of the case. When a force is applied to the case hook 21, the case hook 21 is bent so that the branch portion 25 serves as a fulcrum, and the case hook 21 and the lid hook 11 have rounded case hook rounded portions 24. The lid hook radius part 13 was installed.

[0005]

[Effect] Since each hook end is provided with a rounded shape to give the case hook 21 a spring property, when a force is applied in the direction of the arrow while the lid hook 11 is located on the case hook 21, the lid hook is closed. The tip of the case hook 3 is pushed by the tip of the case 4, and the case hook 21 bends inward of the case 2 with the branch portion 25 shown in FIG. 2 as a fulcrum, so that the case hook 21 and the lid hook 11 are not damaged.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a lid body made of an elastic material such as plastic, having a flat surface on an upper side, one side having a side surface bent downward, and an end having a surface substantially parallel to the upper side. A lid hook 11 is provided, and on the other side, a lid locking portion 12 is provided that extends downward and is hooked upward. Reference numeral 2 denotes a case, in which parts such as batteries (not shown) are housed. The case 2 has a flat upper surface portion and a lower surface portion, a side surface portion connecting the flat surface portion and a fitting portion notched so that the lid 1 can be inserted in a part of the upper surface portion, and a side surface portion has a step portion 22. An inverted L-shaped case hook 21 that branches from the side wall along the side surface of the case is provided. A case locking portion 23 having a portion protruding downward along the fitting portion is provided on the upper surface portion.

Next, attachment / detachment of the lid 1 to / from the case 2 will be described. First, the case locking portion 23 and the lid locking portion 12 are engaged and set as shown in FIG. 2, a force is applied to the lid body 1 in the direction of the arrow, and the tip of the lid hook 11 moves the tip of the case hook 21. When pushed, the lid hook rounded portion 13 and the case hook rounded portion 24 provided at the tips of the respective hooks make a sliding contact. At this time, the case hook 21 bends the case hook 21 inside the case with the branch portion 25 as a fulcrum, and is displaced like a case hook 21 'shown by a dotted line in the drawing. When further force is applied, the lid hook 11 is locked to the case hook 21 and the lid 1 is fixed.

Further, as shown in FIG. 4, a conventional method of assembling the lid 1 can also be used. In this case, in FIG. 1 and FIG. 2, when the lid hook 11 of the lid body 1 is previously inserted between the case hook 21 and the case step portion 22 and force is applied from above the lid body 1, the bent portion is bent. 14 and a bending moment, which is the product of the distance between the force point applied with the force and the force, is applied and the upper surface of the lid 1 bends around the folded portion 14 of the lid 1 as a fulcrum, and the lid locking portion 12 is displaced downward. And slips under the case locking portion 23 so that both are fitted and locked.

When removing the lid body, if the position near the lid locking portion 12 on the upper surface of the lid body 1 is pushed downward, the lid body 1 bends in the same manner as described above, and the lid locking portion 12 causes the case engagement. The lid 1 can be removed by detaching it from the stopper 23.

[0010]

[Effect of the device]

 Since this invention operates as described above, when the lid 1 is set, the lid 1 can be assembled without damage even if force is applied with the lid hook 11 on the case hook 21. Since the lid can be installed and the lid can be incorporated in the same manner as the conventional one, there is an effect that the lid 1 can be easily attached and detached.
