  The hinge bracket is configured by connecting a member attached to the vehicle and a member attaching the vehicle-mounted display via a hinge mechanism. Further, a disc-shaped plate coated with grease is sandwiched between the two members, and the vehicle-mounted display can be held at a predetermined inclination by an appropriate frictional resistance of the contact surface between the members, and The opening / closing operation (inclination angle adjusting operation) is adjusted by human power. The hinge device used in this hinge mechanism is described in, for example, Patent Document 1.

JP 2003-222121 A

  However, in a plate coated with grease, the grease film may be cut (hereinafter referred to as “grease cut”) as the display is repeatedly opened and closed. When the grease break occurs, the display cannot be smoothly opened and closed with respect to the hinge bracket, or the hinge mechanism is deformed by friction due to opening and closing. Furthermore, the vibration of the vehicle generates abnormal noise from the hinge mechanism, which causes a problem that the user is uncomfortable.

  It is an object of the present invention to provide a technique that suppresses the outflow of grease applied to a hinge mechanism for connecting a display to a hinge bracket and makes it difficult to cause a grease break due to opening and closing of the display.

  The hinge bracket of the present invention for solving the above-described problem is the above-described first member on the side on which the vehicle-mounted display is attached and the second member on the side attached to the vehicle are connected via a hinge mechanism. A hinge bracket for attaching an in-vehicle display to the vehicle so as to be openable and closable, and a disc-shaped plate coated with grease is disposed between the first member and the second member. A slit having a predetermined inclination from the radial direction is formed on at least one of the contact surfaces of the plate with the first member and the second member.

  According to the hinge bracket of the present invention, it is possible to suppress the outflow of the grease applied to the hinge mechanism for connecting the display to the hinge bracket, and to make it difficult for the grease to be cut off when the display is opened and closed.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  The hinge bracket 100 according to the embodiment of the present invention is used, for example, in a vehicle 10 as shown in FIG. The in-vehicle display 200 is connected to the hinge bracket 100 so that it can be opened and closed according to use and non-use.

  The operation for opening the display 200 is performed in the direction toward the rear seat 20 as shown by the arrow in FIG. 1, and the operation for closing the display 200 is performed in the direction toward the ceiling 11 of the vehicle 10. In a state in which the display 200 is closed, the display surface of the display 200 and the ceiling 11 (hinge bracket 100) of the vehicle 10 are parallel to each other and do not block the view of the user sitting on the rear seat 20. Further, in this closed state, the hinge bracket 100 and the display 200 are provided with a mechanism that does not open due to the vibration of the vehicle 10.

  On the other hand, when the display 200 is opened, the display surface of the display 200 has a predetermined angle (for example, 0 ° to 110 °) with respect to the ceiling 11 (hinge bracket 100) of the vehicle 10. In this open state, the display 200 is provided with a lock mechanism that can maintain the predetermined angle (opening angle) even when vibration occurs in the vehicle 10. For example, the lock mechanism locks the display 200 with respect to the ceiling 11 (hinge bracket 100) of the vehicle 10 at positions of 70 °, 90 °, and 110 °. In addition, by providing an appropriate frictional resistance to a portion (hinge portion) where the display 200 and the hinge bracket 100 are connected without providing a lock mechanism, the display is inclined with a predetermined inclination with respect to the ceiling 11 of the vehicle 10. 200 may be made holdable.

  Next, FIG. 2 shows a schematic diagram of the hinge bracket 100 when the display 200 is in the open state. In FIG. 2, for ease of understanding, the surface 120 facing the ceiling 11 in the vehicle is drawn downward. In the actual mounting state, the top and bottom are reversed.

  As shown in the figure, the hinge bracket 100 has two hinge portions 110 for connecting one end of the display 200 to a part of the hinge bracket 100 (one end in the traveling direction of the vehicle 10). The two hinge portions 110 are arranged at positions symmetrical with respect to the traveling direction of the vehicle 10. The display 200 is sandwiched between two hinge portions 110 via a display support member 103 for supporting the display 200 and is connected to the hinge bracket 100. The hinge portion 110 is generally called a “clutch”.

  The structure of this hinge part 110 is shown in FIG. As shown in the figure, the hinge part 110 is composed of the display supporting member 103, the first clutch plate 101a, the space ring 102, the second clutch plate 101b, and the hinge bracket in the order from the other hinge part 110 facing each other. 100 clutch support portions 115, a third clutch plate 101 c, and a clutch van 104.

  Each part (101-104) which comprises the hinge part 110 is each provided with the hole (circular shape) of substantially the same diameter, and each part (101-104) is arranged in parallel along the position of each hole. ing. The lock pin 105 is passed through each hole, and each part (101 to 104) is sandwiched between the leaf spring 106 and the nut 107. Thereby, each part (101-104) which comprises the hinge part 110 can each rotate centering on the lock pin 105 (however, the clutch support part 115 of the hinge bracket 100 does not rotate).

  The leaf spring 106 is a plate-like elastic member. Each part (101 to 104) is compressed along the lock pin 105 by using the pressing force in the direction of the nut 107 generated by the contraction force of the leaf spring 106 and the drag force from the nut 107. By this compression, an appropriate frictional resistance is generated on each contact surface of each part (101 to 104), the display 200 can be held at a predetermined inclination, and the display 200 can be opened and closed by the user's force. .

  The display support member 103 supports the display 200. Specifically, the display support member 103 is an L-shaped metal member, and has a long piece 1031 and a short piece 1032 that are coupled at substantially right angles. The display 200 is fixed to the long piece 1031 of the display support member 103. On the other hand, the short piece 1032 of the display support member 103 is provided with a circular hole for allowing the lock pin 105 to pass therethrough.

  As a result, the display support member 103 and the display 200 can integrally rotate with the lock pin 105 as a central axis (indicated by a dotted line). At this time, the rotation angle of the display support member 103 coincides with the angle at which the display 200 opens and closes with respect to the ceiling 11 of the vehicle 10.

  The second clutch plate 101b and the third clutch plate 101c each generate a frictional resistance with the members that contact each other. As a result, a predetermined torque is generated in the member contacting the clutch plates (101b, 101c). Specifically, each clutch plate (101b, 101c) is made of a ring-shaped clutch material. Each clutch plate (101b, 101c) is provided with a circular hole through which the lock pin 105 passes, and rotates around the lock pin 105 as a central axis. In addition, a slit 111 is provided on one ring plane 112 of the second clutch plate 101b and the third clutch plate 101c. Grease (lubricating oil) is applied to the ring plane 112 where the slits 111 are provided. As a result, the second clutch plate 101b and the third clutch plate 101c can generate an appropriate frictional resistance between the contacting members (the grease application surface in the drawing). In the present embodiment, the first clutch plate 101a has the same shape as the second clutch plate 101b and the third clutch plate 101c. However, the ring plane 112 of the first clutch plate 101a may not be provided with the slit 111, and grease may not be applied to the ring plane 112. The first clutch plate 101a serves as a spacer.

  FIG. 4A shows an external view of the slit 111 provided on one ring plane 112 of the second clutch plate 101b and the third clutch plate 101c. FIG. 4B shows an external view of the slit 111 when the second clutch plate 101b is viewed from the direction perpendicular to the ring plane 112. As shown in FIGS. 4A and 4B, the slits 111 are formed at equal intervals along the outer periphery of one ring plane 112 (grease coating surface) of the second clutch plate 101b. The slit 111 has, for example, a linear groove shape. As shown in FIG. 4B, the slit 111 has a predetermined angle from the direction of the centrifugal force (radial direction from the center toward the outer periphery) generated by the rotation of the second clutch plate 101b (third clutch plate 101c). It is tilted in the positive rotation direction by θ (for example, 20 °). Therefore, as shown in FIG. 4A, the second clutch plate 101b and the first clutch plate 101a when the slit 111 is provided are arranged in parallel with the ring plane 112 in the opposite direction. The slits 111 provided in each clutch plate (101a, 101b) are parallel to each other. The grease applied to the ring plane 112 enters the slit 111 and is stored on the grease application surface. In addition, the normal rotation direction of each clutch plate (101a to 101c) is a direction in which the display support member 103 rotates when the display 200 is opened. The direction in which the display support member 103 rotates when the display 200 is closed is referred to as the reverse rotation direction.

  Further, the slit 111 is inclined by a predetermined angle θ from the direction of the centrifugal force generated by the rotation of the second clutch plate 101b (third clutch plate 101c) (radial direction from the center toward the outer periphery). It is possible to prevent the grease from flowing out from the slit 111 in the outer direction of the ring plane 112 (the direction opposite to the center side direction).

  A space ring 102 is sandwiched between the first clutch plate 101a and the second clutch plate 101b. The space ring 102 separates the clutch support portion 115 of the hinge bracket 100 and the display support member 103 by a predetermined distance. Specifically, the space ring 102 is a ring-shaped metal member and is provided with a circular hole for allowing the lock pin 105 to pass therethrough. As a result, the space ring 102 rotates around the lock pin 105 as a central axis. The length of the space ring 102 in the central axis direction is determined according to the size of the display 200 connected to the hinge bracket 100.

  The clutch support part 115 of the hinge bracket 100 supports the hinge part 110 for connecting the display 200 to the hinge bracket 100. Specifically, the clutch support portion 115 of the hinge bracket 100 protrudes in a direction perpendicular to the plane of the hinge bracket 100 (a surface parallel to the ceiling 11 of the vehicle 10), and the two clutch support portions 115 are provided in the vehicle. It is provided opposite to the left-right symmetrical position with respect to the 10 traveling directions. Each clutch support portion 115 of the hinge bracket 100 is provided with a circular hole for inserting the lock pin 105. When the lock pins 105 are passed through the holes provided in the clutch support portions 115, the extension lines (penetration directions) of the lock pins 105 substantially coincide (or become parallel lines). That is, the central axes formed in the two hinge portions 110 provided at positions symmetrical with respect to the traveling direction of the vehicle 10 are substantially on the same straight line. Accordingly, the display 200 integrated with the display support member 103 can be opened and closed with the central axis (on the same straight line) formed in each hinge portion 110 as a support shaft.

  The clutch van 104 uniformly applies the pressing force in the direction of the nut 107 generated by the contraction force of the leaf spring 106 onto the ring plane 112 of the third clutch plate 101c. Specifically, the clutch van 104 is made of a truncated cone-shaped metal member. The clutch van 104 is provided with a circular hole for allowing the lock pin 105 to pass therethrough, and the clutch van 104 rotates around the lock pin 105 as a central axis.

  The display 200 is connected to the hinge part 110 having the above-described configuration, and when the display 200 is opened and closed by the user, a frictional resistance is generated between the parts (101 to 104). It comes to occur.

  Further, the grease applied to one ring plane 112 of each clutch plate (second clutch plate 101b, third clutch plate 101c) is prevented from flowing out by rotation of each clutch plate due to the structure of the slit 111. .

  Furthermore, the force applied to the display 200 by the user when opening the display 100 may be different from the force applied to the display 200 when closing. In general, the force applied when opening is greater than the force applied when closing. Accordingly, the inertial force generated in the grease corresponding to the force applied when opening the display 200 is larger than the inertial force generated in the grease corresponding to the force applied when closing the display 200. In this embodiment, as shown in FIG. 4 (B), the slit 111 provided on the grease application surface of each clutch plate (101b, 101c) has a centrifugal force generated by the rotation of each clutch plate (101b, 101c). Since the direction (radial direction from the center toward the outer periphery) is inclined in the forward rotation direction by a predetermined angle θ, the drag force of the inertial force generated in the grease when the display 200 is opened (forward rotation) is applied to each clutch plate. It works in the center side direction of the ring plane 112 of (101b, 101c). Note that the drag force of the inertial force generated in the grease when the display 200 is closed (reverse rotation) acts in the direction opposite to the center side direction. Accordingly, the grease applied to the application surface of each clutch plate (101b, 101c) is caused by the inertial force generated when the display 200 is closed and the centrifugal force generated by the rotation of the clutch plate (101b, 101c). It flows in the direction opposite to the center side direction, and flows in the center side direction of the ring plane 112 due to inertial force generated when the display 200 is opened. Since the inertial force generated in the grease when the display 200 is opened is larger than the inertial force generated in the grease when the display 200 is closed, the grease easily flows toward the center side of the ring plane 112 and consequently suppresses the outflow of the grease. To do.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

  For example, in the above embodiment, as shown in FIGS. 4A and 4B, twelve slits 111 are provided on each clutch plate (101b, 101c). However, the present invention is not limited to this, and for example, 4, 8, or 16 may be provided.

  Moreover, in the said embodiment, as shown to FIG. 4 (A), the slit 111 is made into the ditch | groove shape. However, the present invention is not limited to this, and the shape of the slit 111 may be a semicircular groove shape, a U groove shape, a V groove shape, or the like.
