Prior to the description of the embodiment of the present disclosure, problems in the conventional HUD device will be briefly described. When concealing the optical path or combiner with the cover when storing the combiner, it is known that the cover covers the open area of the housing by bringing the end of the cover into contact with the end of the open area of the housing from below. It has been. In this structure, the end of the cover that covers and closes the opening region and the end of the housing on the opening region side are in contact with each other.

Since the HUD device is provided on the instrument panel, an object such as a coin or an accessory placed on the instrument panel may move to the top of the cover as the vehicle moves. In this case, when the contact state between the end of the cover and the housing is released by the dead weight of the object moved to the upper part of the cover in the closed state, the object is removed from the gap formed between the housing and the cover. It will fall. Further, when the HUD device is assembled or attached in the factory, or when the vehicle is cleaned, the cover is inadvertently opened due to the force applied to the cover.

In order to solve these problems, it is known that an electromagnetic current is held by always passing a current through a motor that drives the cover so as to maintain the closed state of the cover. However, due to the electromagnetic hold, power is consumed even when the HUD device is not used.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

First, the configuration of a head-up display device (HUD device) 100 according to the embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing an appearance when the cover 120 of the HUD device 100 is in a closed state. FIG. 2 is a perspective view showing an appearance when the cover 120 of the HUD device 100 is in an open state. FIG. 3 is a perspective view showing an appearance of the HUD device 100 when the combiner 130 stands up. FIG. 4 is a perspective view showing the appearance of the HUD device 100 shown in FIG. 3 with the cover 120 and the upper housing 110A constituting the upper portion of the housing 110 removed.

1 to 4, the HUD device 100 includes a housing 110, a cover 120, a combiner 130, a lifting support unit 140, a cover opening / closing unit 150, a combiner driving unit 160, and the like. The HUD device 100 is provided, for example, on an instrument panel (also called a dashboard) of a vehicle.

The housing 110 has an upper housing 110A and a lower housing 110B, and accommodates a combiner 130, a combiner driving unit 160, and a cover opening / closing unit 150. Moreover, the housing | casing 110 accommodates a projection apparatus (not shown) in the back side of the vehicle in the housing | casing 110. FIG. The upper housing 110A has an opening 111 on the upper surface.

The cover 120 is provided so as to cover the opening 111 of the housing 110. The cover 120 performs an opening / closing operation in conjunction with the lifting / lowering operation of the combiner 130. Details of the opening operation of the cover 120 will be described later.

The combiner 130 is, for example, a half mirror, and includes a plate glass and a light semi-transmissive film such as tin or silver deposited on one surface of the plate glass. The combiner 130 has translucency, and is formed so that the user can see the front of the vehicle through the combiner 130.

By the raising / lowering operation of the combiner 130 by the combiner drive part 160, the combiner 130 will be in a stowed state or a standing state. For example, the user can switch the storage state or the standing state of the combiner 130 by performing an operation for instructing driving of an electric motor (not shown) of the combiner driving unit 160. Here, the storage state is a state in which the combiner 130 is stored in the housing 110 of the HUD device 100. Further, the standing state is a state where the combiner 130 is raised, that is, a state where the combiner 130 is raised and appears outside from the opening 111 of the housing 110. The combiner 130 is in an upright state in the first state where the HUD device 100 is used, and is in a retracted state in the second state where the HUD device 100 is not used.

3 is projected onto a projection surface 130a of the combiner 130 shown in FIG. 3 when the combiner 130 is in the standing state. As a result, the image projected on the combiner 130 appears to the user superimposed on the scenery in front of the vehicle. This image is, for example, an image showing the speed of the vehicle, the remaining amount of fuel, or the like, or an image showing the distance to the destination, the direction of travel, the name of the current location, the facility near the current location, the name of the store, etc. .

In the storage state of the combiner 130 shown in FIG. 1, the portion below the cover 120 is embedded in the instrument panel. In that case, it is preferable that the upper surface portion of the cover 120 and the surface of the instrumental panel are substantially horizontal. In this way, the HUD device 100 does not block the driver's field of view when the combiner 130 is stored.

The combiner drive unit 160 is housed on the front side of the vehicle inside the housing 110. The combiner drive unit 160 is a device that raises and lowers the combiner 130 by the power of the electric motor in accordance with the operation of the user (driver or passenger).

The combiner driving unit 160 includes a motor gear 162, a feed screw 166, a movable unit 168, and two combiner support units 134. The motor gear 162 is coupled to an electric motor (not shown) and rotates by driving the electric motor. The feed screw 166 has a gear 164 that meshes with the motor gear 162. The feed screw 166 is coupled to the motor gear 162 via the gear 164 and rotates as the motor gear 162 rotates. As a result, the movable portion 168 screwed to the feed screw 166 moves up and down along the feed screw 166. The feed screw 166 and the movable portion 168 constitute a feed mechanism that moves the movable portion 168 in the vertical direction of the housing 110 by the rotation of the feed screw 166. Note that the upward direction of the housing 110 is a direction indicated by an arrow c in FIGS. 1 to 7, and the downward direction of the housing 110 is a direction indicated by an arrow d in FIGS. 1 to 3.

The combiner support part 134 is connected to the movable part 168 and supports the combiner 130. The power of the vertical movement of the movable part 168 by the feed mechanism is transmitted to the combiner support part 134, and the combiner 130 is raised and lowered.

The elevating support portions 140 are plate-like members arranged on the left and right sides of the combiner 130, respectively. As shown in FIG. 12 described later, a pair of protrusions 132 are provided on both sides of the combiner support portion 134. A slit 142 is provided in a portion of the lifting / lowering support portion 140 corresponding to the movement region of the protrusion 132 (see FIG. 5) of the combiner support portion 134.

The slit 142 is formed linearly along the vertical direction of the housing 110 (the direction of the arrow c or the arrow d, that is, the ascending / descending direction of the combiner 130). The slit 142 is an area where the protrusion 132 formed on the combiner support part 134 slides when the combiner 130 transitions between the housed state and the standing state.

A protrusion 132 is formed on the elevating support 140 side (that is, the outer surface) of the combiner support 134. Each of the protrusions 132 (see FIG. 5) is inserted into the slit 142, penetrates the slit 142, and engages with a guide portion 154 (see FIGS. 5 and 7) described later.

The configuration example of the HUD device 100 has been described above.

Next, details of the operation of the HUD device 100 will be described. Hereinafter, the operation when the combiner 130 transitions from the stowed state to the standing state or from the standing state to the stowed state will be described.

[Raising / lowering operation of combiner 130]
The raising / lowering operation | movement of the combiner 130 is demonstrated using FIG.5, FIG6 and FIG.8. FIG. 5 is a cross-sectional view taken along line VV of the HUD device 100 when the combiner 130 is in the standing state. FIG. 6 is a cross-sectional view taken along line VI-VI of the HUD device 100 when the combiner 130 is in the retracted state. FIG. 8 is a cross-sectional view taken along line VIII-VIII of HUD device 100 when combiner 130 is in a locked state.

In the standing state of the combiner 130 shown in FIG. 5, the combiner support part 134 moves downward (in the direction of the arrow d) by the drive of the electric motor. With this movement, the combiner 130 fixed to the combiner support part 134 also moves downward in the casing 110.

Further, along with this movement, the protrusion 132 formed on the combiner support portion 134 moves downward from the upper end portion of the slit 142. The protrusion 132 can move downward until it reaches the lower end of the slit 142 (state shown in FIG. 8). When the protruding portion 132 reaches the lower end portion of the second guide portion 154b, the combiner 130 is in the storage state shown in FIG. Further, when the protrusion 132 moves downward and reaches the lower end of the slit 142, the combiner 130 is in the locked state shown in FIG.

In the storage state of the combiner 130 shown in FIG. 8, the combiner support portion 134 moves upward (in the direction of the arrow c) by driving the electric motor. With this movement, the combiner 130 fixed to the combiner support part 134 also moves upward in the housing 110.

Further, along with this movement, the protrusion 132 formed on the combiner support portion 134 moves upward from the lower end portion of the slit 142. The protrusion 132 can move upward until it reaches the upper end of the slit 142 (state shown in FIG. 5). When the protrusion 132 reaches the upper end of the slit 142, the combiner 130 is in the standing state shown in FIG.

In the standing state of the combiner 130 shown in FIG. 5, the protrusion 132 is positioned at the upper end of the slit 142. In this standing state, the user can visually recognize the image projected on the projection surface 130a.

Thus, in the transition between the stowed state (including the locked state) and the standing state of the combiner 130, the protrusion 132 is supported by the combiner support part 134 by sliding up and down along the slit 142. The combiner 130 moves up and down in the direction of arrow c or arrow d. Thereby, a storage function for the combiner 130 is realized.

[Opening / Closing Operation of Cover 120]
Next, details of the opening / closing operation of the cover 120 will be described with reference to FIGS. FIG. 7 is an explanatory diagram of the cover opening / closing part 150. FIG. 8 is a cross-sectional view taken along line VIII-VIII of HUD device 100 when cover 120 is in the locked state. In FIG. 7, the cover opening / closing part 150 is shown in a simplified manner, and the through hole 155 and the oblong hole 156 (see FIGS. 12 and 13) and the like are omitted.

As shown in FIG. 4, the cover opening / closing part 150 is a plate-like member provided outside the lifting support part 140 on both the left and right sides of the casing 110. That is, the cover opening / closing part 150 is disposed on both sides of the combiner support part 134 and opens / closes the cover 120 following the lifting / lowering operation of the combiner 130. Specifically, the first boss 143 (convex portion) of the lifting support portion 140 is inserted into the through hole 155 of the cover opening / closing portion 150, and the second boss 144 of the lifting support portion 140 is the length of the cover opening / closing portion 150. It is loosely fitted in the circular hole 156 (see FIG. 12). That is, the cover opening / closing part 150 is attached to the lifting support part 140 so as to be rotatable about the first boss 143. As shown in FIGS. 5 to 6, the cover 120 has a first gear portion 122. The first gear portion 122 is fixed to the cover 120.

The cover opening / closing part 150 includes a rotation shaft C ₁ , a second gear part 152, and a guide part 154. The center line of rotation of the rotating shaft C ₁ is fixed to penetrate the housing 110 in the lateral direction. Cover opening and closing unit 150 is rotated about an axis of rotation _{C 1.} Here, the first boss 143 inserted into the through hole 155 of the cover opening and closing unit 150 is a rotary shaft _{C 1.}

The second gear portion 152 is fixed to the main body of the cover opening / closing portion 150 and meshes with the first gear portion 122 (see FIG. 13). When the cover opening / closing part 150 is driven to rotate, the second gear part 152 and the first gear part 122 transmit a rotational motion to rotate the cover 120. That is, as the cover opening / closing part 150 rotates, the cover 120 also rotates. Cover 120 about the gear shaft C ₂ of the first gear portion 122, the rotation direction of the cover opening and closing unit 150 rotates in the opposite direction.

The guide part 154 extends downward from above as a whole. In other words, the guide portion 154 has a bent shape that is bent, but is not bent at a steep angle in a U shape. A protrusion 132 formed on the combiner support part 134 is inserted into the guide part 154. The protrusion 132 formed on the combiner support part 134 passes through the slit 142 and is also inserted into the guide part 154.

The guide part 154 includes a first guide part 154a, a second guide part 154b, and a third guide part 154c. The upper end portion of the second guide portion 154b is connected to the first guide portion 154a, and the lower end portion of the second guide portion 154b is connected to the third guide portion 154c. Here, the extending direction D2 of the second guide portion 154b (hereinafter referred to as “second direction D2”) is the extending direction D1 of the first guide portion 154a (hereinafter referred to as “first direction D1”). It is different from

In the standing state of the combiner 130 shown in FIG. 5, when the combiner support portion 134 moves downward (in the direction of the arrow d) by the drive of the electric motor, the protrusion at the upper end portion of the slit 142 of the HUD device 100. The part 132 also moves downward. When the protrusion 132 moves through the slit 142 in the downward direction of the housing 110, the protrusion 132 simultaneously slides in the guide portion 154 of the cover opening / closing portion 150.

The first guide part 154a is formed in the cover opening / closing part 150 so as to coincide with the position and shape of the slit 142 when the protrusion 132 moves along the first guide part 154a. In other words, the first guide portion 154a extends in a direction parallel to the ascending / descending direction of the combiner 130 in the first state (the use state of the HUD device 100). Thereby, when the protrusion part 132 moves along the 1st guide part 154a, the rotation to the direction of the arrow i or the arrow j (refer FIG. 6) of the cover opening / closing part 150 is restrict | limited. Therefore, the position of the cover 120 including the first gear portion 122 meshed with the second gear portion 152 of the cover opening / closing portion 150 can be fixed in the open state.

After the protruding portion 132 reaches the upper end of the second guide portion 154b connected to the first guide portion 154a, the combiner support portion 134 is moved downward (arrow d) by further driving the electric motor. ), The protrusion 132 moves the second guide portion 154b downward. Since the second guide portion 154b extends in the second direction D2 different from the first direction D1, as shown in FIGS. 150 is rotated in the direction of arrow j around the rotation axis _{C 1.} Further, as the protrusion 132 moves the second guide portion 154b upward (direction of arrow c), the cover opening and closing unit 150 is rotated in the direction of arrow i about an axis of rotation C _1.

As the cover opening / closing portion 150 rotates in the direction of the arrow i or the arrow j, the first gear portion 122 of the cover 120 meshed with the second gear portion 152 of the cover opening / closing portion 150 has a rotation axis C ₂ ( It rotates in the direction of arrow k or arrow l (see FIG. 6) around the gear shaft of the first gear portion 122. That is, the cover 120 opens and closes with the rotation of the cover opening / closing part 150. Specifically, when the first gear portion 122 rotates in the direction of the arrow k, the closed cover 120 rotates in the direction of the arrow n (see FIG. 5) and is in the open state. As a result, as shown in FIG. 5, an opening 111 a is formed in the moving direction of the combiner 130, and the combiner 130 can project from the opening 111 a of the housing 110. On the other hand, when the first gear portion 122 rotates in the direction of the arrow l, the cover 120 in the open state rotates in the direction of the arrow m shown in FIG. As a result, as shown in FIG. 6, the opening 111 a shown in FIG. 5 is eliminated, and the combiner 130 housed in the housing 110 is not visible from the outside of the housing 110.

In this way, the cover opening / closing part 150 is arranged so that the extending direction D2 (second direction D2) of the second guide part 154b, which is at least part of the guide part 154, and the extending direction of the slit 142 are different. Is done. In one example, the extending direction D2 of the second guide portion 154b is determined according to the speed of the opening / closing operation of the cover 120. In one example, the length in the extending direction D2 of the second guide portion 154b is determined according to the rotation range of the cover opening / closing portion 150 in the direction of arrow i or arrow j. Specifically, when the cover 120 starts to shift from the open state to the closed state, the protrusion is positioned at the upper end of the second guide portion 154b, and the protrusion 132 when the cover 120 is in the closed state. Is positioned at the lower end of the second guide portion 154b, and the length of the second guide portion 154b in the extending direction D2 is determined.

Thus, in the HUD device 100, the cover 120 can be opened and closed in conjunction with the lifting and lowering operation of the combiner 130 by the protrusion 132. Thereby, the raising / lowering operation | movement of the combiner 130 and the opening / closing operation | movement of the cover 120 can be implemented with one electric motor. Therefore, in the HUD device 100, it is not necessary to provide a drive mechanism for opening / closing the cover 120 separately from the lifting / lowering operation of the combiner 130, so that the HUD device 100 can be configured in a compact manner.

After the protruding portion 132 reaches the lower end of the second guide portion 154b connected to the third guide portion 154c, the combiner support portion 134 is moved downward in the casing 110 by the drive of the electric motor (arrow). In the direction d), the protrusion 132 moves the third guide portion 154c downward. As a result, as shown in FIG. 8, the protrusion 132 contacts the inner surface of the slit 142 and the inner surface of the third guide portion 154c.

FIG. 9 is a diagram illustrating an example of the third guide portion 154c. FIG. 10 is an enlarged view around the protrusion 132 in FIG. 9 and 10, the lifting support portion 140 is indicated by a broken line, and the cover opening / closing portion 150 is indicated by a solid line.

As shown in FIG. 9, the third guide portion 154c extends in a third direction D3 different from the extending direction D2 (second direction D2) of the second guide portion 154b. In the second state in which the HUD device 100 is not used, the third guide portion 154c has a component in the ascending / descending direction of the force acting on the protrusion 132 downward or zero when the cover 120 is pressed. Has a shape. Specifically, the angle φ2 formed by the first direction D1 and the third direction D3 is smaller than the angle φ1 formed by the first direction D1 and the second direction D2. That is, the bending direction of the third guide portion 154c with respect to the second guide portion 154b is opposite to the bending direction of the second guide portion 154b with respect to the first guide portion 154a.

In one example, the inner side surface of the third guide portion 154 c has a region parallel to the inner side surface of the slit 142. For example, the radius of the protrusion 132 is 3 mm, and the upper end of the contact point P between the protrusion 132 and the third guide 154c and the area parallel to the inner surface of the slit 142 among the inner surfaces of the third guide 154c. The distance from Q is 2 mm.

In one example, the third guide portion 154c is parallel to the third direction D3, third and first side 1541c closer from the rotation axis _{C 1,} the rotation axis _{C 1} second farther than the first side surface 1541c Side surface 1542c. Further, an angle θ formed by the normal direction x at the contact P at which the protrusion 132 contacts the first side surface 1541c with the direction y in which the protrusion 132 slides on the slit 142 when the combiner 130 is retracted is 90 degrees. In other words, the third direction D3 is parallel to the ascending / descending direction in the second state. When the protrusion 132 slides on the third guide part 154c, as shown in FIG. 11, the center axis L1 of the slit 142 of the lifting support part 140 and the center of the third guide part 154c of the cover opening / closing part 150 are provided. The axis L2 coincides. In this case, the inner surface of the slit 142 with which the protrusion 132 contacts and the inner surface of the third guide portion 154c with which the protrusion 132 contacts are parallel to each other.

When the cover 120 is pressed in this state, the driving force is applied so as to rotate in the i direction shown in FIG. 6 about the rotation axis C ₁ via the first gear portion 122 and the second gear portion 152. It acts on the cover opening / closing part 150. As a result, on the inner side surface of the third guide portion 154c with which the protrusion 132 contacts, a force in the normal direction of the inner surface acts on the protrusion 132. Then, the protrusion 132 held between the inner surface of the slit 142 and the inner surface of the third guide portion 154c, which are parallel to each other, is stationary. That is, the component of the force acting on the protrusion 132 in the up and down direction is zero. As a result, the rotation of the cover opening / closing part 150 is suppressed. When the rotation of the cover opening / closing part 150 is suppressed, the opening of the cover 120 is also suppressed, and the cover 120 is locked.

Of the side surfaces of the third guide portion 154 c, the normal direction x at the contact point P where the projection portion 132 contacts the side surface on the rotation center side of the rotation axis C ₁ is the projection portion 132 having the slit 142 when the combiner 130 is retracted. The angle θ formed with the sliding direction y may be less than 90 degrees. In other words, the third direction D2 is in the second state, in a direction (the rotation axis _{C 1} of the third guide portion 154c is inclined to the rotation axis _{C 1} side from the communication setting point of the second guide portion 154b (Direction to approach). In this case, for example, the end portion of the third guide portion 154c is closed, and the side surfaces of the third guide portion 154c are parallel to each other. The length of the parallel side surface is 2 mm, for example.

When the cover 120 is pressed in this state, a force in the normal direction of the inner side surface acts on the projection part 132 on the inner side surface of the third guide part 154c with which the projection part 132 is in contact. Try to move downward, not upward. That is, the component of the force acting on the protrusion 132 in the up-and-down direction is downward. However, since the guide portion 154 prevents the protrusion 132 from moving downward, the protrusion 132 does not move any further. As a result, the rotation of the cover opening / closing part 150 is suppressed. When the rotation of the cover opening / closing part 150 is suppressed, the opening of the cover 120 is also suppressed, and the cover 120 is locked.

As described above, in the present disclosure, by providing the guide portion 154 with the third guide portion 154c having the specific shape as described above, the cover 120 is locked without using the electromagnetic hold of the motor. be able to.

(Other embodiments)
5 to 6, the case where the cover 120 and the cover opening / closing part 150 form the first gear part 122 and the second gear part 152 has been described. However, the present disclosure is not limited to such a configuration, and any configuration may be used as long as the cover 120 opens and closes as the cover opening / closing portion 150 rotates.

For example, the elevating support part 140 is not limited to the structure shown in the embodiment, and may be any as long as it can support the combiner support part 134 so as to be able to be raised and lowered.

In the embodiment, the first boss 143 of the vertical movement support portion 140 which is inserted into the through hole 155 of the cover opening and closing unit 150 (convex portion) is next to the rotation axis C _1, the cover opening and closing unit 150 has been described the configuration for rotating . That is, in this case, the elevating support part 140 has a first boss 143 that is a convex part that rotatably supports the cover opening / closing part 150. However, the configuration of the rotation axis C ₁ of the cover opening and closing unit 150 is not limited thereto. For example, a convex part may be provided in the cover opening / closing part 150, a concave part (including a hole) may be provided in the elevating support part 140, and both may be engaged.

The present disclosure can be used for a head-up display device that raises and lowers a combiner.
