  The inclined surfaces 155B of the claws 155a to 155c of the battery lid 112 are formed so as to correspond to the inclined surfaces 172B of the locking portions 172a to 172c, respectively. That is, the inclined surfaces 155B of the claws 155a to 155c of the battery lid 112 are formed to have the same angle as the inclined surfaces 172B of the locking portions 172a to 172c, respectively. Further, the inclined surfaces 155A of the claws 155a to 155c of the battery lid 112 are formed so as to correspond to the inclined surfaces 172D of the locking portions 172a to 172c, respectively. That is, the inclined surfaces 155A of the claws 155a to 155c of the battery cover 112 are formed to have the same angle as the inclined surfaces 172D of the locking portions 172a to 172c, respectively.

  In the restricting portion 173, two-step step-like grooves 173B and 173D having different depths are formed so as to be arranged side by side. Comparing the two grooves, the groove 173B is shallower and the groove 173D is deeper. In addition, an inclined surface 173A that smoothly connects the upper surface 171A and the groove 173B is formed between the upper surface 171A of the outer peripheral portion 171 and the groove 173B. Further, an inclined surface 173C that smoothly connects the grooves 173B and 173D is formed between the grooves 173B and 173D.

  Note that the inclined surfaces 156A of the ribs 156a to 156c of the battery lid 112 are formed so as to correspond to the inclined surfaces 173C of the restricting portions 173a to 173c, respectively. That is, the inclined surfaces 156A of the ribs 156a to 156c of the battery lid 112 are formed to have the same angle as the inclined surfaces 173C of the restricting portions 173a to 173c, respectively.

[How to install battery cover 112]
Next, a method for mounting the battery lid 112 will be described with reference to FIGS. FIG. 14 shows a state before the battery cover 112 is mounted on the lower case 132 (main body 111). 15 to 18 show the states of the battery lid 112, the packing 113, the locking portion 172, and the regulating portion 173 from when the battery lid 112 is attached to the lower case 132 to when the battery lid 112 is closed, as in FIG. This is schematically shown in the figure.

  15 to 18 show only a set of claws 155, ribs 156, locking portions 172, and restricting portions 173 in plan view. However, each of the claw 155a, the rib 156a, the locking portion 172a and the regulating portion 173a, the claw 155b, the rib 156b, the locking portion 172b and the regulating portion 173b, and the claw 155c, the rib 156c, the locking portion 172c, and the regulating portion 173c Both sets move similarly in FIGS. 14 to 18.

  When the user attaches the battery lid 112 to the lower case 132, the user first attaches the battery lid 112 to the lower case 132 so as to cover the opening of the lower case 132 with the attachment portion 154 facing down. Then, the user rotates the battery lid 112 in the direction of the arrow A2 (hereinafter referred to as the closing direction) while applying a force in the direction of the arrow A1 (hereinafter referred to as the pushing direction) in FIG. 112 is fixed to the lower case 132.

  Here, when the battery lid 112 is attached to the lower case 132, the respective claws 155 of the battery lid 112 are aligned so as to be inserted into the insertion portions 172 </ b> A of the respective locking portions 172 of the lower case 132. Then, the tips of the ribs 156 of the battery lid 112 abut on the inclined surfaces 173A of the restricting portions 173 of the lower case 132. Further, the tips of the ribs 156 slide on the inclined surfaces 173A of the restricting portions 173 and come into contact with the grooves 173B of the restricting portions 173 as shown in FIG. Then, the battery lid 112 cannot be pushed any further.

  Here, as shown in FIG. 15, in a state where each rib 156 is in contact with the groove 173 </ b> B of each regulating portion 173, the back surface of the lid portion 151 of the battery lid 112 is held at a position higher than the upper end of the packing 113. As described above, the height of the rib 156 and the depth of the groove 173B are adjusted. Accordingly, the lid 151 of the battery lid 112 does not contact the packing 113 and a gap is generated between them.

  At this time, since the angle of the inclined surface 155B of each claw 155 is the same as the angle of the inclined surface 172B of each locking portion 172, each claw 155 interferes with the inclined surface 172B of each locking portion 172, and the battery cover The movement of 112 is prevented from being hindered.

  Next, when the battery lid 112 is pushed and rotated in the closing direction (when the battery lid 112 is pushed and slid in the rotation direction), each rib 156 is guided to the groove 173B of each regulating portion 173. That is, the tips of the ribs 156 slide along the grooves 173B while being in contact with the grooves 173B of the restricting portions 173.

  At this time, since the battery lid 112 does not move in the pushing direction, the battery lid 112 can be rotated without crushing the packing 113 while ensuring a gap between the lid portion 151 of the battery lid 112 and the packing 113.

  Further, when the ribs 156 are in contact with the grooves 173B of the restricting portions 173, the height of the ceiling portion 172C is adjusted so that the upper ends of the claws 155 do not contact the ceiling portions 172C of the locking portions 172. Has been. Therefore, the claws 155 and the ceiling portions 172C of the locking portions 172 interfere with each other, and the movement of the battery cover 112 is prevented from being hindered.

  Next, when the battery lid 112 is rotated by a predetermined amount or more in the closing direction and the tip of each rib 156 exceeds the groove 173B of each regulating portion 173, the inclined surface 156A of each rib 156 is changed as shown in FIG. Then, it comes into contact with the inclined surface 173C of each regulating portion 173 and slides on the inclined surface 173C.

  At this time, since the angle of the inclined surface 155A of each claw 155 is the same as the angle of the inclined surface 172D of each locking portion 172, each claw 155 and the inclined surface 172D of each locking portion 172 interfere with each other, The movement is prevented from being hindered.

  Then, when the inclined surface 156A of each rib 156 finishes sliding on the inclined surface 173C of each restricting portion 173, the tip of each rib 156 contacts the groove 173D of each restricting portion 173 as shown in FIG. That is, each rib 156 is smoothly guided from the groove 173B to the groove 173D by the inclined surface 156A of each rib 156 and the inclined surface 173C of each restriction portion 173. Then, the battery lid 112 cannot be pushed any further.

  Here, the dotted line in the horizontal direction in the lid portion 151 of the battery lid 112 in FIG. 17 indicates the position of the upper end of the packing 113 before being crushed by the battery lid 112. That is, in a state where each rib 156 is in contact with the groove 173D of each restricting portion 173, the back surface of the lid portion 151 of the battery lid 112 is lower than the upper end of the packing 113 before being crushed and higher than the lower end of the packing 113. Therefore, the height of the rib 156 and the depth of the groove 173D are adjusted. Accordingly, the back surface of the lid portion 151 of the battery lid 112 is held at a position where the packing 113 is crushed by a predetermined amount, and the packing 113 is crushed by the battery lid 112 with a predetermined strength. As a result, a pressure exceeding a predetermined strength is prevented from being applied to the packing 113.

  Further, when the battery lid 112 is pushed and rotated in the closing direction (when the battery lid 112 is pushed and slid in the rotation direction), each rib 156 is guided to the groove 173D of each regulating portion 173. That is, the tip of each rib 156 slides along the groove 173D while being in contact with the groove 173D of each restricting portion 173.

  At this time, since the battery lid 112 does not move in the push-in direction, the battery lid 112 can be rotated without applying a pressure exceeding a predetermined strength to the packing 113. Accordingly, it is possible to prevent the packing 113 from being twisted, deformed or damaged.

  Further, in a state where each rib 156 is in contact with the groove 173D of each restricting portion 173, the ceiling portion is prevented so that the upper end of the inclined surface 155A of each claw 155 and the lower end of the inclined surface 172D of each locking portion 172 do not interfere with each other. The height of 172E is adjusted. Therefore, the inclined surface 155A of each claw 155 and the inclined surface 172D of each locking portion 172 interfere with each other, preventing the movement of the battery lid 112 from being hindered.

  Then, as shown in FIG. 18, the battery lid 112 is rotated in the closing direction until each claw 155 contacts the wall 172 </ b> F of each locking portion 172.

  Thereafter, when the application of force to the battery cover 112 is stopped, a force in the direction opposite to the arrow A1 (the direction opposite to the pushing direction) is applied to the battery cover 112 by the repulsive force of the packing 113. Then, each claw 155 of the battery lid 112 is hooked on the ceiling portion 172E of each locking portion 172, and the position of the battery lid 112 is fixed.

  Thus, the packing 113 is compared with the case described above with reference to FIG. 1 to FIG. The amount by which the battery lid 112 is rotated while being crushed can be reduced. Further, the pressure applied to the packing 113 can be regulated to a predetermined level or less by the action of each rib 156 of the battery lid 112 and the groove 173D of each regulating part 173 of the lower case 132. That is, as described above with reference to FIGS. 1 to 3, when the battery cover 112 is closed, the battery cover 112 is pushed more than necessary and the packing 113 is prevented from being crushed more than necessary. . As a result, the packing 113 can be prevented from being twisted, deformed, damaged, and the like, and the hermeticity of battery storage can be improved.

  In addition, the ribs 156 of the battery lid 112 and the grooves 173D of the respective restricting portions 173 of the lower case 132 allow a predetermined force to be applied to the packing 113 even if a force in the pushing direction is applied to the battery lid 112 after the battery lid 112 is mounted. No pressure exceeding the strength is applied. That is, as described above with reference to FIGS. 1 to 3, the battery lid 112 is pushed more than necessary after the battery lid 112 is attached, and the packing 113 is prevented from being crushed more than necessary. As a result, the packing 113 is excessively crushed and the battery lid 4 is prevented from being displaced, and the packing 2 is prevented from being twisted, deformed, damaged, and the like, and the sealing property of the battery housing can be improved.

  Further, when the battery cover 112 is rotated in the direction opposite to the closing direction and removed from the lower case 132, the ribs 156 of the battery cover 112 ride on the grooves 173 </ b> B of the regulating portions 173 of the lower case 132 on the way. As a result, the lid 151 of the battery lid 112 floats slightly above the surface of the lower case 132. As a result, it becomes easy for the user to hook his / her finger on the lid 151, and it becomes easy to remove the battery lid 112 from the lower case 132.

  In addition, for example, since the part of the lower case 132 that hooks the claw 155 of the battery lid 112 of each regulating portion 173 has a two-step shape, the battery lid 112 may be unintentionally detached from the lower case 132. Is prevented. That is, even if the fitting between each claw 155 of the battery lid 112 and the ceiling portion 172E of each regulating portion 173 is released, each battery claw 155 is hooked on the ceiling portion 172C of each regulating portion 173, so Is prevented from coming off the lower case 132.

<2. Modification>
Hereinafter, modifications of the above-described embodiment of the present invention will be described.

  FIG. 19 shows a modification of the locking portion 172 of the lower case 132.

  The locking portion 172 'in FIG. 19 differs from the locking portion 172 in FIG. 13 in that an inclined surface 172G is formed instead of the ceiling portion 172C and the inclined surface 172D.

  The inclined surface 172G is formed between the insertion portion 172A and the ceiling portion 172E so as to connect the upper surface 171A of the outer peripheral portion 171 and one end of the ceiling portion 172E.

  Although not shown, the inclined surface 155A of each claw 155 of the battery lid 112 is formed to correspond to the inclined surface 172G of each locking portion 172 '. That is, the inclined surface 155A of each claw 155 is formed to have the same angle as the inclined surface 172G of each locking portion 172 '. This prevents the claws 155 and the inclined surfaces 172G of the locking portions 172 'from interfering with each other, preventing the movement of the battery lid 112 from being hindered.

  Further, if only the pressure applied to the packing 113 by the battery lid 112 is restricted, the ceiling part 172C of the locking part 172 and the groove 173B of the restriction part 173 can be omitted. That is, it is possible to omit the process of rotating the battery lid 112 without contacting the packing 113 by the rib 156 of the battery lid 112 and the groove 173B of the restricting portion 173.

  Furthermore, the numbers of the claws 155 and ribs 156 of the battery cover 112 and the engaging portions 172 and the restricting portions 173 of the lower case 132 are not limited to the above-described example, and are set to an arbitrary number of 2 or more. be able to. Further, the numbers of the claws 155 and the ribs 156 and the numbers of the locking portions 172 and the restricting portions 173 are not necessarily matched.

  The present invention can also be applied to lids other than battery lids. The shape of the battery cover is not limited to the above-described disk-shaped cover that is opened and closed by rotating in the circumferential direction. For example, according to the present invention, a packing is provided between the lid and the main body portion to improve the sealing performance, and the lid is slid in parallel so that the claw provided on the lid is hooked on the locking portion of the main body portion. It can also be applied to.

  Furthermore, the present invention can also be applied to lids for devices other than portable devices for vehicles.

  Moreover, although the example which uses an O-ring for packing was shown above, this invention is applicable also when using other types of packing, such as X ring and D ring.

  Furthermore, the embodiments of the present technology are not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present technology.
