Description

  The present invention relates to a microwave detector, an infrared detector, a target detection device, and other in-vehicle electronic devices, and more specifically to an improvement in a hinge structure provided in a member that opens and closes such as a display unit.

  2. Description of the Related Art A target detection device (microwave detector) that detects and notifies a microwave transmitted from a vehicle speed measurement device is known. This target detection device recognizes the reception of microwaves from the vehicle speed measurement device even when it receives microwaves sent from a malfunction source such as an automatic door of a convenience store using the same frequency as the speed measurement device. As a result, there is a problem that an unnecessary alarm is issued. In view of such circumstances, recent target detection devices store position information of malfunction sources, recognize the position of the vehicle by GPS, and detect the microwave when the vehicle is positioned at the malfunction source. Also, it is possible to prevent unnecessary alarms from being issued by controlling so as not to generate alarms.

  Further, the device for measuring the speed of the vehicle is not limited to the one using the above-mentioned microwave. For example, a vehicle traveling on the road is detected by two loop coils embedded and installed under the road. Some vehicles measure based on a time difference between detection signals output from two loop coils. This type of vehicle speed measurement device cannot be detected by the target detection device using the above-described microwave detection because microwaves are not output.

  Therefore, the target object detection device that stores and holds the position information of the detection object and issues an alarm when the position of the vehicle detected by the GPS and the position of the detection object are in a predetermined relationship. (For example, Patent Document 1). In addition, if location information such as accident occurrence points is stored in memory, when the vehicle reaches around the accident occurrence point, it notifies the driver of the fact and contributes to safe driving can do. In this way, the target to be registered is not limited to a specific object, and various objects can be applied.

  In vehicle-mounted electronic devices such as this type of target detection device, there is a type with a screen display unit that performs screen display such as liquid crystal or EL. This type of in-vehicle electronic equipment with a screen display has recently been increasing the number of types and contents of alarm display, while also improving the display screen size and increasing the screen size, etc. Came to be planned. Thus, the driver can know various information appropriate for the situation, and can receive information that is preferable for safe driving when traveling on an unfamiliar road.

  On the other hand, in a frequent area such as around the driver's home, the driver knows the installation position of the two speed measurement devices and the position of the contents to be notified by other in-vehicle electronic devices, and may not require an alarm. In such a case, there is a person who feels bothersome if a uniform alarm is issued when he / she comes near a registered target. For such people, there are also in-vehicle electronic devices equipped with a mode in which a warning is not issued in a registered area. In such a case, in order to avoid battery consumption, it is conceivable to turn off the display screen in the registered area.

When the method of turning off the display screen is adopted, as described above, in the case of a vehicle-mounted electronic device having a screen display unit with a large screen size as described above, the screen disappears and the vehicle mounted with a large black screen display unit. Electronic devices will be present in the driver's sight, such as on the dashboard, which is not very good looking. Of course, even if the display screen remains on, there is a person who feels that it is not preferable that a large screen display section exists in the driver's field of view when there is no need to see (information to be acquired). unknown.
In view of this, as a new vehicle-mounted electronic device for solving such a problem, the following configuration has been devised (in order to facilitate the understanding of the description, reference is made to FIG. 1 showing a preferred embodiment of the present invention). To explain). That is, as shown in FIG. 1, the new in-vehicle electronic device includes a display panel 3 for displaying notifications on a display screen and a control unit for performing various notifications, and the speaker and the control unit are case bodies. Store in 1. A display panel storage case 2 for storing the display panel 3 is attached to the case body 1 so as to be rotatable. An open state in which the display panel storage case 2 as shown in FIG. 1A is erected so that the display screen of the display panel 3 is exposed and visible from the outside, and a display panel storage case as shown in FIG. 2, the display screen is in a non-exposed state with respect to the outside, and is in a closed state that is not visible from the outside. Furthermore, the control unit also performs notification by screen display when in the open state, and operates so as not to perform notification by screen display when in the closed state. The presence or absence of screen display notification can be switched by opening / closing the display unit, and the power consumption can be reduced by closing.

JP 2006-46976 A

  In the above-described new configuration, it is necessary to rotate the display panel storage case 2 forward and backward within a predetermined angle range, and at least hold the posture in an open state and a closed state. Therefore, it is necessary to use a hinge structure including a mechanism that allows rotation and locks the rotation at a desired position. This type of conventional in-vehicle electronic device having a function of notifying a target object is, for example, a type that can be attached to both a dashboard and a sun visor, and is provided with a solar panel. Is attached to the case body so as to be rotatable, the angle position of the solar panel with respect to the case body is arbitrarily set according to the installation location, and the posture is maintained. The fixing structure in such a device is to loosen or tighten the screw exclusively, and in the case of a device that maintains the state once the rotation angle is determined, such as a solar panel, As described above, a structure using screws cannot be put to practical use if it is repeatedly opened and closed during use.

  Moreover, although it is not a vehicle-mounted electronic device, for example, in the case of a foldable mobile phone, there is one that opens and closes a display portion and fixes it at two positions, a closed state and an open state. The hinge structure in such a cellular phone is a separate unit component having a hinge portion having a function of rotating and locking, and the structure is complicated and has been developed and provided for each product. Therefore, when the number of manufactured products is very large like a mobile phone, the structure is originally complicated when applied to a small number of manufactured devices compared to a mobile phone like this kind of in-vehicle electronic device. There are factors that lead to higher costs, and the use of dedicated parts increases the cost and cannot be put to practical use.

  An object of the present invention is to provide an in-vehicle electronic device and a hinge component that have a hinge structure that is simple in structure, can meet various demands at low cost, and that shares components as much as possible.

  In order to achieve the above-described object, an in-vehicle electronic device according to the present invention is (1) an in-vehicle electronic device including a panel that is linked to a case main body through a hinge part so as to be able to rotate forward and backward. The panel is configured to take two postures, at least a standing and open state, and a closed state facing the surface of the case body, and the hinge part is configured such that one end side of the rod-shaped body is on the case side. The other end of the rod-like body is inserted into a through-hole provided in the side edge of the panel so that the panel is centered around the hinge part. The latching claw is provided on the other end side of the hinge part body, and the latching claw has a spring property, the tip is in a free state, and the tip is on the outer peripheral surface side. Protruding protrusions are provided, and the inner periphery of the through hole A plurality of protrusions for contacting and stopping the protrusions of the locking claws are provided at a predetermined angular position, and one of the plurality of protrusions is the protrusion when the panel is closed. A first protrusion provided in a position to hold the closed state in contact with the other protrusion, and the other one of the plurality of protrusions is in contact with the protrusion when the panel is opened. The second protrusion is provided at a position for holding the open state.

  In the present invention, the hinge part having the above-described configuration is used, and the panel can be rotated forward and backward with a simple configuration performed by providing a plurality of protrusions at predetermined positions on the inner peripheral surface of the through hole provided in the panel. The posture can be held at a predetermined position. Moreover, the opening angle of the panel can be changed by changing the position of the protrusion, and can meet various requirements. When forming different types of hinge mechanisms, the hinge parts can be used in common by appropriately designing the positions of the protrusions.

  (2) It is good to form the said latching claw so that it may curve and extend along the periphery of a rod-shaped main body. By adopting such a configuration, it is possible to satisfactorily receive the force at the time of contact with the protrusion during rotation and appropriately absorb the vehicle vibration on the circumferential surface. Furthermore, even if the diameter of the hinge part is relatively small, it is possible to easily give the locking claw sufficient strength while the locking claw has sufficient spring properties. Furthermore, since the diameter of the hinge part can be easily reduced, cost reduction and design flexibility are increased.

  (3) The second protrusions may be provided at a plurality of locations. If it does in this way, the angle which hold | maintains in the state which opened the panel will become two or more, and since the user can change the opening angle of a panel according to a condition, usability improves.

  (4) The panel may be further provided with a third projection for opening the panel at a predetermined angle and contacting the projection that has passed over the second projection to prevent further opening. The projection is positioned between the second projection and the third projection, and the projection is sandwiched between the two projections, so that the panel is prevented from rotating in either the forward or reverse direction, and held in that position. can do.

  (5) A plurality of sets of the locking claws and the plurality of protrusions may be provided. In the embodiment, two sets are received, but by receiving a plurality of sets, rotation / stop (fixation) can be performed more stably. Of course, this invention may install only one set.

  (6) The non-rotatable cantilevered support mechanism is provided with a latch receiving portion having a hole portion for inserting and supporting one end side of the hinge part in the case body, and an inner peripheral surface of the hole portion and the hinge It is possible to prevent rotation by providing a non-circular locking surface on at least a part of the outer peripheral surface on one end side of the component, and bringing the locking surfaces into contact with each other. In the embodiment, the locking surface is a flat surface, but various configurations such as a polygonal shape, a curved surface that is not a perfect circle such as an ellipse, or an uneven surface that fits each other on opposite surfaces can be adopted. . Note that the present invention is not limited to such a non-rotatable state by the locking surface, and is fixed by screwing or uses a frictional force generated by fitting (the outer dimension on one end side of the hinge part is a hole). It is possible to adopt various other methods such as making it larger than the inner diameter of the portion.

(7) It is good to comprise so that the front-end | tip of the one end side of the said hinge component may penetrate the said hole part, and the detachment | leave from the said latching receiving part is suppressed. In the embodiment, the configuration for preventing the separation is realized by adopting a configuration in which the protruding portion 28a at the tip of the first locking claw 28 protrudes from the hole 24 and is latched outside thereof.
(8) The panel may be a display panel. Of course, it may be other than the display panel.

  (9) As the hinge component of the present invention, the configuration of the hinge component in the in-vehicle electronic device described in (1) to (8) above is adopted.

  In the present invention, it is possible to realize a hinge structure that is simple in structure, can meet various demands at low cost, and shares parts as much as possible.

It is a figure which shows suitable one Embodiment of this invention. It is a figure which shows suitable one Embodiment of this invention. It is a figure which shows an example of hinge components. It is sectional drawing which shows a hinge mechanism part. It is a figure explaining an effect | action.

  1 to 5 show a preferred embodiment of the present invention. The in-vehicle electronic device 15 of the present embodiment is a device that acquires current position information of a vehicle and radio wave information flying from the outside, and issues an alarm / notification when the acquired information matches a set condition. The case body 1 constituting the appearance of the in-vehicle electronic device 15 has a flat shape with a substantially rectangular plane, and its upper surface is configured to be higher on the front side and lower on the rear side. That is, the thickness (height) h1 of the front portion 1a is set larger than the thickness (height) h2 of the rear portion 1b. In this embodiment, the front side refers to a side located on the front side (front side) of the vehicle when the on-vehicle electronic device (on-vehicle electronic device) is placed at a predetermined position (for example, on the dashboard) in the vehicle interior. . Conversely, when viewed from the driver, the rear side of the in-vehicle electronic device comes to the front.

  A flat rectangular display panel storage case 2 is disposed above the rear portion 1b that is one step lower than the case body 1. The display panel storage case 2 is attached to the case body 1 by a hinge mechanism 5 in the vicinity of the boundary of the rear portion 1b on the front portion 1a side so as to be rotatable forward and backward within a predetermined angle range. Thereby, the state where the display panel storage case 2 as shown in FIG. 1A stands and the state where the display panel storage case 2 falls as shown in FIG. 1B can be taken. As shown in FIG. 1B, in the state in which the display panel storage case 2 is closed, the display panel storage case 2 fits within a step with the front portion 1a on the rear portion 1b of the case main body 1, and the main body. The entire case 1 and the display panel storage case 2 are made to look like one casing. Strictly speaking, the thickness of the display panel storage case 2 is larger than the difference in thickness between the front portion 1a and the rear portion 1b (h1-h2). In such a case, the rear side becomes thicker, but the difference is set appropriately so that it can be seen integrally.

  The display panel 3 is attached to one surface of the display panel storage case 2 (the lower surface facing the case main body 1 when in a collapsed state). The display panel 3 is realized using, for example, an organic EL display or a liquid crystal display, and is electrically connected to a control unit built in the case body 1 by a flexible cable. Thereby, in the state in which the display panel storage case 2 is tilted (closed), the display panel 3 faces the upper surface of the rear portion 1b of the storage case 2 and is not visible from the outside. When the display panel storage case 2 is erected and opened, the display panel 3 is also erected and exposed, and is visible from the rear side, that is, the driver side.

  Furthermore, in this embodiment, the solar panel 4 is attached to the other surface of the display panel storage case 2 (the surface that is not exposed to the case body 1 when it is in a collapsed state and is always exposed). The solar panel 4 is stored in the display panel storage case 2 in a state of being back-to-back with the display panel 3. As a result, it is possible to reduce the size of the device, and also to exert strength as a function of reinforcing members of each other, so that it is not necessary to provide a separate reinforcing plate, or even if it is temporarily provided Can be configured thinly as a whole.

  A switch portion 7 is disposed at the front end of the upper surface of the rear portion 1 b of the case body 1. The switch unit 7 is exposed to the outside when the display panel storage case 2 is raised and opened (opened), and can be operated by the user. When the display panel storage case 2 is tilted and closed (closed), The display panel storage case 2 is covered with the display panel storage case 2 and cannot be touched by the user, and cannot be operated. In other words, by keeping the display panel storage case 2 in a closed state, it becomes impossible to operate the switch unit 7 even during operation, so that the switch unit 7 is accidentally touched, and unexpected processing and operations are performed. It can be prevented from being performed. Further, in the case of this type of conventional device, the switch unit 7 is always exposed, so that it is inevitably reduced in size to secure space for the solar panel and the display screen, and the operability is deteriorated. However, in this embodiment, there is no such limitation, and the size and shape of each button can be made relatively large and each can be separated, making it easy to see and intended. It is possible to suppress as much as possible the occurrence of erroneous operations such as pressing multiple buttons at the same time or pressing another button by mistake.

  A microwave receiver and a radio receiver are arranged inside the front side of the front part 1 a of the case body 1, and a GPS receiver is arranged inside the upper surface side of the front part 1 a of the case body 1. An alarm lamp 6 is arranged on the rear surface of the rear portion 1b of the case body 1. The alarm lamp 6 is composed of LEDs of a predetermined color. In addition to the alarm lamp 6, a lamp (light emitting means) used other than the alarm, such as a pilot lamp indicating ON / OFF of the power supply, is also prepared.

  In this embodiment, the display panel storage case 2 is provided on the rear portion 1b side of the case main body 1, and the GPS receiver is provided on the front portion 1a side of the case main body 1. As shown in FIG. Even when the case 2 is erected, most of the front portion 1a is not covered with the display panel storage case 2, so that even when the display panel is opened, GPS radio waves can be received well. Yes, you can get your own vehicle location information at any time.

  Further, a DC jack 9 for connecting the power switch 8 and the cigar plug cord is disposed on one side surface of the case body 1. The case body 1 also includes a speaker, a wireless receiver, a remote control receiver, and the like. Further, information on the target (position information including longitude / latitude, type information, etc.) is stored in the database. In the database, information related to a certain target at the time of shipment (position information including longitude and latitude, type information, etc.) is registered. Further, various position information can be registered / updated in the database according to use.

  The microwave receiver receives a microwave of a predetermined frequency band and sends the received signal to the control unit. The predetermined frequency band is, for example, a frequency band including a microwave frequency emitted from the vehicle speed measuring device. The radio receiver receives radio waves of a predetermined frequency that come. The remote control receiver performs data communication with the remote control (portable device: handset) and performs various settings for the in-vehicle electronic device 15. The switch unit 7 is also connected to the control unit so that the same setting as the remote control can be performed. The GPS receiver receives a GPS signal, obtains a current position from the received GPS signal, and sends position information (mild, latitude) of the obtained current position to the control unit.

  The control unit executes predetermined processing based on information input from the various input devices (receivers, etc.), and uses the output devices (display panel 3, alarm lamp 6, speaker, etc.) to generate predetermined alarms. -Output a message. As the predetermined processing for determining the alarm content based on the information input from the input device, the same basic processing as that in the conventional art can be used. That is, when a signal having a certain condition is received / acquired, a corresponding alarm is output. Note that alarms using a speaker include a buzzer and voice.

  A flat rectangular box-shaped battery storage case 10 having an upper opening is detachably attached to the bottom surface of the case body 1. A storage battery 11 is stored in the battery storage case 10. The storage battery 11 is connected to the solar panel 4 and the DC jack 9 via a charging circuit and stored, and can supply power to the control unit and others via a discharging circuit. The on-vehicle electronic device support 18 is integrated with and supported by the on-vehicle electronic device 15 by inserting the claw portion 18a into the slit portion 10a provided in the battery storage case 10.

  In this embodiment, the control unit recognizes the open / closed state of the display panel storage case 2, and when the display panel storage case 2 is in an upright and open state, it issues an alarm by screen display using the display panel 3, and displays When the panel storage case 2 is in the closed state, control is performed so as not to issue an alarm by screen display using the display panel 3 (the display panel 3 is turned off). Accordingly, when the alarm is performed using the screen display, the alarm lamp 6 is not activated. When the mode is not performed using the screen display, the alarm lamp 6 is activated. The alarm using the speaker is performed in any state. The open / closed state is recognized by, for example, providing a magnetic sensor at a predetermined position in the case body 1 and providing a magnet at a predetermined position of the display panel storage case 2 so that the magnetic sensor detected by opening / closing the display panel storage case 2 This can be done based on the change (magnitude) of the magnetic force of the magnet. When the screen is closed, the notification by the screen display is not performed, so that power consumption can be significantly reduced.

  As a user operation for performing the switching control, the user only needs to close the screen, and there is no need to perform a special operation such as a switch operation for turning off the screen display. In addition, since the screen portion can be closed, the driver is not distracted by the screen and there is no danger. Even when the screen portion is closed as described above, the notification is made by the speaker and the alarm lamp 6, so that the notification content is not displayed on the screen and the notification content is not understood. Furthermore, when the display panel storage case 2 is closed, the display panel storage case 2 looks like a flat rectangular body as a whole, and a warning is given by sound (including sound) and a lamp. It becomes a form similar to an on-vehicle electronic device that detects a vehicle speed measuring device of a type, and can transmit sufficient information without a sense of incongruity to the driver.

  According to this embodiment, when driving on a road that normally passes in commuting, living area, etc., the display panel storage case 2 (display panel 3) is closed and the notification content can be known by sound (alarm lamp 6). At the same time, when driving on a road that does not normally pass, such as when going out on holidays, more information can be obtained visually by opening the display panel storage case 2 and informing the screen display. In such a usage method, since the power is normally used with low power consumption, sufficient power can be stored in the storage battery, and when the display panel storage case 2 is opened and used, the stored power is used. Thus, it is possible to perform notification by screen display for a long time.

  Also, usually the screen is closed and the cigar plug cord is removed from the DC jack 9 so that it can operate for a long time only with the energy of the solar panel 4 and the storage battery, and the screen is opened and the DC jack only when going out. It is also possible to connect a cigar plug cord to 9 and receive power from the vehicle battery to operate for a long time. In this way, the cigar plug cord can be used normally without being disturbed, and it can be stably operated for a long time by receiving power supply from the vehicle only when screen display is required. .

  In addition, in the case of an in-vehicle electronic device having a new form and configuration as described above, it is expected that a user frequently opens and closes the display panel storage case 2, and the opening and closing operation can be easily performed. It is necessary to stably hold the open state and the closed state. It is also necessary to prevent the display panel storage case 2 from rattling due to vehicle vibration. Furthermore, it is not preferable that the open / close state changes carelessly. Therefore, in the present embodiment, the structure shown in FIG. 2 and subsequent figures is adopted as the hinge mechanism 5 for realizing the function.

  That is, the notch 22 is provided at a predetermined position near both ends of one side of the display panel storage case 2, and the cylindrical part 20 is provided outside the notch 22. The cylindrical portion 20 is formed with a through hole 21 penetrating in the axial direction. A hinge component 25 is inserted into the through hole 21 so as to be able to rotate forward and backward around the axis.

  Further, in the vicinity of the front part 1a side boundary of the rear part 1b of the case main body 1, a latch receiving part 23 that cantilever-supports and fixes one end of the hinge part 25 is provided at a position corresponding to the notch part 22. . That is, the latch receiving portion 23 is formed with a hole 24 extending in the axial direction. Then, the latch receiving portion 23 enters the cutout portion 22 of the display panel storage case 2 and is aligned so that the axial centers of the through hole 21 and the hole portion 24 coincide with each other. The display panel storage case 2 is arranged in this state, and in this state, the hinge part 25 is inserted from the outside of the through hole 21 and the tip of the hinge part 25 is inserted into the hole part 24 of the latch receiving part 23. As a result, the hinge part 25 is fixed to the latch receiving part 23 so as not to rotate. Further, the display panel storage case 2 is prevented from being detached by the hinge part 25, and at the same time with respect to the axis of the hinge part 25. It can be rotated in the forward and reverse directions, and can be opened and closed within the range of two postures shown in FIGS.

  The fixing structure of the hinge part 25 in the latch receiving part 23 is as follows. First, as shown in FIG. 3, the hinge part 25 is provided with a locking surface 27 made of a parallel plane in a shape obtained by removing both sides in the radial direction on one end side of a rod-like (cylinder, column) body 26. A pair of first locking claws 28 are formed on the same plane as the locking surface 27 and project outward in the axial direction.

  Further, on the side of the latch receiving portion 23, the inner shape of the hole portion 24 is set to a dimensional shape that substantially matches the outer shape on one end side of the hinge part 25. That is, the inner surface shape of the hole 24 is a shape including two parallel locking surfaces 24a. The axial length of the hole 24 is obtained by adding the axial length of the locking surface 27 of the hinge part 25 and the length excluding the protruding portion 28a at the tip of the first locking claw 28. It is almost equal. Thus, when one end of the hinge part 25 is inserted into the hole 24 so that the locking surfaces 27 and 24a are aligned, as shown in FIG. 4, the protruding portion 28a at the tip of the first locking claw 28 is Through the hole 24, the subsequent removal of the hinge part 25 is suppressed. And since the latching surface 27 provided in the hinge component 25 and the 1st latching claw 28 contact the latching surface 24a provided in the hole 24, rotation of the hinge component 25 is prevented. Thereby, the hinge component 25 is cantilevered by the latch receiving portion 23 so as not to rotate. Further, since the locking surface 27 of the hinge part 25 and the first locking claw 27 are in contact with the locking surface 24a of the hole 24 on a relatively wide surface, the direction of rotation with respect to the hinge part 25 Even if this force is applied, the force can be distributed and received over a wide area, so that damage to the hinge part 25 and the like is suppressed.

  On the other hand, a mechanism for stopping the display panel storage case 2 that is linked to be able to rotate forward and backward on the other end side of the hinge part 25 at a predetermined position is as follows. First, the second locking claw 30 is formed at the other end of the hinge part 25 so as to extend along the circumference of the main body of the hinge part 25. That is, the wall part 29 is formed at the other end of the hinge part 25 so as to extend in the diameter direction, and the second locking claws 30 are respectively connected to both ends of the wall part 29. The second locking claw 30 has a curved shape and a free end, and a protrusion 30 a that protrudes toward the outer peripheral surface is provided at the distal end of the second locking claw 30. Therefore, the second locking claw 30 has a spring property, and when the protruding portion 30a is urged toward the center side of the hinge part 25, the second locking claw 30 bends, and the protruding portion 30a at the tip is centered. When the urging force is released, it returns to its original state (position) due to springiness (elastic restoring force). Furthermore, in the present embodiment, two second locking claws 30 are provided and arranged point-symmetrically with respect to the center of the hinge part 25, but the present invention is not limited to this and one may be used. In addition, since the hinge part 25 is formed of resin, the second locking claw 30 is curved as described above and the distal end is in a free state, thereby exhibiting an appropriate elastic force, that is, a spring property.

  Further, in the through hole 21 of the cylindrical portion 20, a band-like (linear) protrusion is formed so as to extend in the axial direction at a predetermined angular position. The protrusions come into contact with the protrusions 30 a of the second locking claws 30 to prevent rotation, and contact the protrusions 30 a when the display panel storage case 2 is closed with respect to one second locking claw 30. The first protrusion 31 for holding the closed state and the second protrusion 32 for holding the display panel storage case 2 in contact with the protrusion 30a when the display panel storage case 2 is opened (raised). And a second protrusion 32 for holding the display panel storage case 2 in contact with the protrusion 30a when the display panel storage case 2 is opened (raised) (to prevent it from collapsing and closing), and display panel storage A third protrusion 33 for contacting the protrusion 30a that has passed over the second protrusion 32 when the case 2 is opened (standing) at a predetermined angle and prevents further opening. Yes.

  That is, the protrusion 30a of the second locking claw 30 is set close to the inner peripheral surface of the through hole 21 of the cylindrical portion 20 but in a non-contact state, so that the display panel storage case 2 and thus the cylindrical portion 20 are smooth. The tip (vertex) of each protrusion 31-33 protrudes toward the center of the through hole 21 from the tip position of the protrusion 30a of the second locking claw 30, and with the rotation of the tubular portion 20, When the protrusions 31 to 33 come into contact with the protrusion 30a, smooth rotation is suppressed, and when the display panel storage case 2 is further rotated from that state in a predetermined direction, the first and second protrusions 31 and 32 become the protrusions. 30a is pushed down (the second locking claw 30 is elastically deformed and bent) and gets over (further rotates). And when these 1st, 2nd protrusions 31 and 32 get over protrusion part 30a, the 2nd latching claw 30 will return to an original state with elastic restoring force. That is, the protrusion 30 a returns to the original position and comes into contact with the first and second protrusions 31 and 32. Therefore, when the display panel storage case 2 tries to rotate in the direction opposite to the rotation direction when the protrusion 30a is exceeded, the first protrusion 31 or the second protrusion 32 comes into contact with the protrusion 30a, and the rotation is suppressed. Is done. Accordingly, by appropriately setting the positions of the first and second protrusions 31 and 32, as shown in FIGS. 5A and 5B, the display panel storage case 2 is in a closed state or stands up. It can be kept open. Of course, when the display panel storage case 2 is rotated by applying a force of a certain level or more in the opposite direction, the second locking claw 30 is bent and the protrusion 30a moves to the center side. Is acceptable.

  Further, when the second protrusion 32 gets over the protrusion 30a, the protrusion 30a is set so as to be positioned between the second protrusion 32 and the third protrusion 33 as shown in FIG. . Accordingly, when the display panel storage case 2 is further rotated in the opening direction, the third protrusion 33 hits the protrusion 30a, and further movement is suppressed. Therefore, the posture can be maintained without rattling in the state in which the display panel storage case 2 is opened. In the present embodiment, the upper surface of the display panel storage case 2 is the front portion 1a of the case body 1 with the display panel storage case 2 opened to a predetermined angle (the angle at which the second protrusion 32 rides over the protrusion 30a). The third protrusion 33 does not necessarily have to be provided because it is set so as to prevent the body from falling further.

  Further, by changing the angular position at which the second protrusion 32 (third protrusion 33) is provided, the angle at which the display panel storage case 2 is held open can be changed. That is, the hinge component 25 can be shared and used for different in-vehicle electronic devices.

  In the present embodiment, the display panel storage case 2 can be held in two positions (postures), ie, a closed state and an open state. However, the protrusion provided in the through hole 21 of the cylindrical portion 20. By increasing the number, the number of positions where the display panel storage case 2 is stopped (fixed posture) can be increased to three or more. Furthermore, when increasing the number of installation, the 2nd latching claw 30 is good to be one piece.

  Moreover, in this embodiment, although the display panel 3 and the solar panel 4 were accommodated in the display panel storage case 2, of course, it is not necessary to provide any one, and other things may be sufficient.
