Description

  The present invention relates to an attachment device and an electronic device for detachably attaching an electronic device to a predetermined location, and more particularly to an electronic device that can be easily attached to an external force such as vibration and an attachment device used therefor. It is.

  In recent years, electronic devices having various functions such as a navigation function and an audio visual function are widely used. The usage form is not only mounted on an automobile or the like and used for in-vehicle use, but also can be removed from the vehicle and used for portable use if necessary. Furthermore, it is considered that the mounted vehicle is not limited to an automobile and is used by being attached to a bicycle.

  Conventionally, as this type of attachment device, for example, there is one shown in the following Patent Document 1 (Japanese Patent Laid-Open No. 2005-350064). A display device that obtains and displays information on the position (longitude, latitude, etc.) of a running bicycle in addition to information such as the vehicle speed and the number of crank rotations of the bicycle is mounted on the bicycle. In this mounting method, a case is detachably attached to a bracket attached to a handle, and a display device is accommodated in the case. The display device can perform a display function even when the case is removed from the bracket.

  As a specific configuration for attaching and detaching the display device, for example, there is one shown in Patent Document 2 (Japanese Patent Laid-Open No. 2007-193185) below. The structure includes a band around which the fixing tool is wound around the fixing tool main body, the handlebar, and the like, and an insertion member. The fixture body has an opening. The fitting member is integrated with the fixture main body by being fitted into the opening. The display device main body is provided with an engaging portion that slides and engages with the fitting member. Therefore, the display device body can be detachably attached to the fixture by a sliding operation.

  According to the above conventional attachment device, the display device can be used not only by being mounted on a bicycle but also by being removed. However, since the display device receives external force such as vibration in the mounted state, it is necessary to fix the display device so that it does not come off due to an impact. For that purpose, for example, the one shown in the following Patent Document 3 (Japanese Patent Laid-Open No. 8-268361) is conceivable. This conventional example is a technique for attaching / detaching a battery unit to / from a battery unit mounting portion provided on a bicycle frame in an electric bicycle. Specifically, the battery unit is provided with an L-shaped hook and a convex portion. On the battery unit mounting portion side, an L-shaped metal fitting that can be engaged with and detached from the L-shaped hook and a concave portion that fits the convex portion are provided.

  The L-shaped bracket is configured to rotate in synchronization with the rotating key. When the battery unit is mounted on the battery unit mounting portion, the protrusion on the battery unit side is inserted and engaged with the recess on the battery unit mounting portion side, and then the L-shaped bracket is rotated with the key. Is engaged with the L-shaped hook. As a result, the battery unit is locked and fixed to the battery unit mounting portion, so that the battery unit is not detached from the battery unit mounting portion due to an impact. On the other hand, when removing the battery unit from the battery unit mounting portion, the L-shaped metal fitting is rotated by a key operation to release the engaged state with the L-shaped hook and release the locked state. Therefore, the battery unit can be removed from the battery unit mounting portion.

  Next, the operation of the mounting apparatus 10 according to the configuration of the above-described embodiment will be described. First, the attachment device 10 is attached to the handle bar 40. In this mounting, the arm 502 is largely rotated with respect to the holding portion main body 50 to sandwich the handle bar 40, and then the tip of the arm 502 is fixed to the holding portion main body 50 with the screw 503. This fixed state is ensured when the spacer 504 is greatly compressed.

  Next, a method for attaching the electronic device 20 to the attachment device 10 will be described.

First, the convex portion 303 provided in the receiving portion 301 is inserted into the concave portion 302 on the bottom surface 201 side of the electronic device 20, and then the upper portion of the electronic device 20 is held as shown in FIGS. 1 (a) and (b). Push in the direction of part 30. As a result, the upper surface 202 of the electronic device 20 is slid into the lower surface of the elastic plate 304 so as to push up the elastic plate 304. Then, the convex portion 306 is inserted into the concave portion 305, and at the same time, the convex portion 308 on the holding unit 30 side is inserted into the concave portion 307 formed on the back surface 203 of the electronic device 20 . Simultaneously with the operation, the engagement between the concave portion 307 formed on the back surface 203 of the electronic device 20 and the convex portion 308 on the holding portion 30 side is also achieved.
This eliminates the need for complicated operation for installation.

  In addition, since the elastic plate 304 is made of a material that is elastically biased compared to the receiving portion 306, the vehicle vibrates up and down violently depending on road conditions and the like, and thereby the engagement state of the convex portion 306 with the concave portion 305 is released. In consideration of the possibility, the third protrusion 308 is arranged at the upper surface position (position close to the elastic plate 304) on the back surface of the electronic device.

  Note that when the convex portion 308 is fitted into the concave portion 307, the protruding edge 309 abuts on the inclined surface 313 to retract the locking claw 312 into the space portion 310. And then. When the protruding edge 309 passes through the locking claw 312, the locking claw 312 protrudes into the recess 307. As a result, the locking claw 312 is locked to the protruding edge 309.

  The electronic device 20 attached to the attachment device 10 is held by the holding unit 30 at three locations of the bottom surface 201, the top surface 202, and the back surface 203. This holding state is maintained when the elastic plate 304 presses the upper surface 202.

  When the electronic device 20 in the attached state receives an external force in the upward direction, since the convex portion 308 is fitted and engaged with the concave portion 307, the electronic device 20 is biased upward against the elastic force of the elastic plate 304. To be prevented. When the electronic device 20 receives an external force in the forward direction, the locking claw 312 of the convex portion 308 is locked to the protruding edge 309 of the concave portion 307, and thus the electronic device 20 may tilt forward. Be blocked.

  When removing the electronic device 20, the elastic plate 307 is forced to bend upward against the elastic force, and at the same time, the upper portion of the electronic device 20 is pulled forward, thereby engaging the concave portion 305 and the convex portion 306. The combined state can be released. In other words, the electronic device 20 can be tilted forward by removing the convex portion 306 from the state where the convex portion 306 is fitted in the concave portion 305.

  Further, when the electronic device 20 is forcibly tilted forward, the locking claw 312 comes into contact with the protruding edge 309 and is released from the state where it is forcibly climbed and locked. Therefore, the convex portion 308 is released from the state in which the convex portion 308 is fitted into the concave portion 307.

  Therefore, according to the above-described embodiment of the present invention, the electronic device 20 attached to the attachment device 10 has the bottom surface 201 supported by the fixed receiving portion 301 and the top surface 202 pressed by the elastic plate, and the recess 302. An engagement state is obtained by fitting the convex portion 303 into the concave portion 305 and fitting the convex portion 306 into the concave portion 305. Therefore, attachment of the electronic device 10 can be achieved simply by pushing the electronic device 10, and removal can be achieved simply by pushing up the elastic plate 304 and pulling the electronic device 20 forward.

  Further, in the state where the electronic device 20 is attached, since the convex portion 308 is fitted into the concave portion 307, the electronic device 20 moves upward with respect to the holding portion 30 even if an external force is applied to the electronic device 20 upward. There is no bias. Therefore, when the electronic device 20 is mounted on a bicycle and a large impact is applied to the electronic device 20 with respect to the holding portion 30 due to vibration or the like, the electronic device 20 is prevented from being biased. As a result, the elastic plate 304 is not biased upward by an external force. That is, according to the attachment device 10 to which the electronic device 20 is attached, the attachment state is not affected by impact force such as vertical vibration.

  In addition, since the locking claw 312 is locked to the protruding edge 309, the electronic device 20 is prevented from being biased away from the holding portion main body 50 by an external force. Therefore, according to the attachment device 10 to which the electronic device 20 is attached, the attachment state is not affected by an impact force such as vibration in the front-rear direction.

  In the present invention, the concave portions 302, 305, and 307 are provided on the electronic device 20 side, and the convex portions 303, 306, and 308 are provided on the holding portion 30 side, but the concave portions 302, 305, and 307 are provided on the electronic device 20 side. The arrangement may be changed to various arrangements such as providing the convex portions 303, 306, and 308 on the holding unit 30 side.

  In addition, in the said Example, although the recessed parts 302 and 305 and the convex parts 303 and 306 were each provided in two places, you may make it provide in one place.

  In the present invention, the receiving portion 301 is provided so as to extend along the bottom surface 201 of the electronic device 20, and the elastic plate 304 is provided so as to extend along the top surface 202 of the electronic device 20. However, the receiving portion 301 is provided so as to extend along one side surface of the electronic device, and the elastic plate 304 is extended so as to extend along the side surface opposite to the side surface on which the receiving portion 301 is provided. It can also be provided.
