Description

The present invention relates to a lamp unit for a vehicle including a sensor and an irradiation device.

Various sensors have been conventionally arranged in the vehicle. For example, Japanese Patent Application Laid-Open No. 2019-23428 discloses a device that detects the movement of a user standing near a sliding door by a sensor and opens and closes the sliding door based on the information detected by the sensor. According to the device, the sliding door opens and closes only when the user performs a specific action, so that the user can easily open the sliding door even when the hand is occupied, for example.

Japanese Unexamined Patent Publication No. 2019-23428

However, on the other hand, in this type of device, it is common to dispose a sensor in the lower part of the vehicle, that is, in the lower part of the vehicle in order to detect the movement of the foot of the occupant. Therefore, it is difficult for the user to visually grasp the position of the sensor, and there is a problem that it is difficult to perform an appropriate operation at an appropriate position. As a result, in this type of device, the problem that the door does not open even though the user operates is likely to occur.

In addition, a projection technique for displaying the position where the user should perform an operation on the road surface has also been proposed (Japanese Patent Laid-Open No. 2019-173508). According to this type of device, if the user operates at a position near the projected image displayed on the road surface, the sensor detects the operation of the user. It is considered that this can reduce the problem that the door does not open even though the user operates.

However, on the other hand, it is difficult for the user to visually recognize the displayed projected image during the daytime, when the road surface is shining brightly, or when it is raining. Can still cause the problem of not opening.

The inventor of the present invention intended to display the position where the user should operate with respect to the sensor mounted on the vehicle, that is, the detection range of the sensor, to the user by using the irradiation device.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle lamp unit capable of allowing a user to perceive the detection range of a sensor.

The vehicle lamp unit of the present invention that solves the above problems is
It is a vehicle lamp unit including a sensor mounted on the lower part of the vehicle and an irradiation device for irradiating a vehicle outer plate at a position corresponding to the detection range of the sensor.

The vehicle lamp unit of the present invention can easily allow the user to perceive the detection range of the sensor.

It is explanatory drawing which schematically explains the cross section through the irradiation apparatus in the lamp unit for a vehicle of Example 2. FIG.

The vehicle lamp unit of the present invention includes a sensor mounted on the lower part of the vehicle and an irradiation device.

Since the sensor is mounted on the lower part of the vehicle, it is usually difficult for the user to visually recognize the sensor.

The irradiation device in the lamp unit for a vehicle of the present invention irradiates the outer panel of the vehicle at a position corresponding to the detection range of the sensor. In other words, it emits light toward the vehicle skin at the corresponding position to illuminate the vehicle skin. In addition, in this specification, "the position corresponding to the detection range of the sensor" includes the position corresponding to the foot of the user standing facing the vehicle outer plate irradiated by the irradiation device in the detection range of the sensor. Means to be.
If the position of the irradiation device and the position of the vehicle outer panel to which the irradiation device is irradiated are appropriately selected, the user can easily see the sign of the light obtained by the irradiation of the irradiation device even in fine weather. .. This makes it easier for the user to perceive the detection range of the sensor according to the vehicle lamp unit of the present invention.

Further, since the irradiation target of the irradiation device is a specific area in a specific vehicle outer plate, according to the vehicle lamp unit of the present invention, the amount of light and the color of the light emitted by the irradiation device are appropriate for the vehicle outer plate. You can select the amount of light and the color of the light. This also has the advantage that the light sign that is easy for the user to see can be displayed by the irradiation device.

Further, the distance from the irradiation device to the outer panel of the vehicle is shorter than the distance from the irradiation device to the road surface. Therefore, according to the vehicle lamp unit of the present invention, it is advantageous to clearly project the sign of light by the irradiation device.

Further, since the distance from the irradiation device to the outer panel of the vehicle is relatively short, the sign of light can be clearly projected even when it is raining or snowing, for example.
The vehicle lamp unit of the present invention can also make the user easily perceive the detection range of the sensor.

Hereinafter, the vehicle lamp unit of the present invention will be described for each component thereof.

The vehicle lamp unit of the present invention includes a sensor and an irradiation device.
Of these, the sensor may be mounted on the lower part of the vehicle and is not particularly limited, but a so-called kick sensor that detects the movement of the user's foot is preferable. The sensor may detect the user's movement in a known manner such as a capacitance type or an ultrasonic type.

The irradiation device may be able to show the detection range of the sensor to the user by irradiating the outer panel of the vehicle. For example, the irradiation device may simply irradiate the outer panel of the vehicle with light, or may display a design such as a character or an image on the outer panel of the vehicle by irradiating the light. The characters and images may be stationary or flat, or may be moving or three-dimensional, such as moving images and holograms. The irradiation device may be integrated with the sensor or may be a separate body.

In either case, a light sign is displayed on the outer panel of the vehicle due to the irradiation of the irradiation device. Then, the sign can indicate the detection range of the sensor to the user.

The design displayed by the irradiation device may be, for example, various logos, symbols, symbols or images such as house marks, or some kind of textual message.

The irradiation device may only irradiate the vehicle outer plate, or may irradiate other regions in addition to the vehicle outer plate. Here, the vehicle outer plate is a portion of the vehicle outside the vehicle interior and forming a plate shape, such as a body, a bumper, a door, and various garnishes.

If the sensor in the vehicle lamp unit of the present invention is a kick sensor, the vehicle outer panel is preferably near the door that opens and closes based on the detection result of the kick sensor, and particularly preferably near the back door. be. Examples of the vehicle outer panel in this case include a rear bumper, a rear diffuser, a lower end portion of the back door, a back garnish, and other regions located below the back door in the body, which are components of the lower part of the vehicle.

The irradiation device may be arranged at a position where it can irradiate the outer plate of the vehicle, and the arrangement position of the irradiation device may be appropriately set according to the position of the outer plate of the vehicle. For example, if the vehicle outer panel is any of the above-mentioned components of the lower part of the vehicle, the irradiation device is preferably arranged in a portion of the back door located above the lower end.

The irradiation device may only display a sign indicating the detection range of the sensor on these vehicle outer panels by irradiation, or may have other functions.

For example, the irradiation device may irradiate the road surface in addition to the vehicle outer panel, and may display a light sign on the road surface as well. The sign of light displayed on the road surface may be related to the sensor in the vehicle lamp unit of the present invention, or may be irrelevant to the sensor. The irradiation device may simply illuminate the road surface so that the user can visually recognize his / her feet, especially in an environment where the amount of light is insufficient, such as at night or in rainy weather.

When the sign of light displayed on the road surface by the irradiation device is related to the sensor, for example, the sign displayed on the road surface may be a sign indicating the detection range of the sensor.
In this case, the detection range of the sensor is highly reliable to the user by displaying a sign indicating the detection range of the sensor on the road surface and the vehicle outer panel slightly above the road surface. Can be perceived. In this case, it is preferable to set the detection range of the sensor between the two signs.

If the light sign displayed on the road surface by the irradiation device is not related to the sensor, the sign displayed on the road surface is, for example, the presence or absence of an abnormality that occurred during parking, the presence or absence of notification from the support center, the time, and the parking time. , It may be a sign that tells us about future changes in the weather.

The vehicle lamp unit of the present invention may include a license lamp that irradiates a license plate (also referred to as a license plate) in addition to the irradiation device. In this case, the license lamp and the irradiation device may be treated as an irradiation unit. The license lamp may be separate from the irradiation device or may be integrated with the irradiation device.
In these cases, the vehicle lamp unit of the present invention further has a function as a license lamp.

When the license lamp is integrated with the irradiation device in the vehicle lamp unit of the present invention, it is preferable to share a part of the portion that functions as the license lamp, such as a housing and a cover lens, with the irradiation device. In this case, by reducing the size of the irradiation device and the license lamp, or reducing the number of these parts, it is possible to contribute to the miniaturization, weight reduction, cost reduction, and the like of the vehicle lamp unit of the present invention.

The irradiating device may irradiate visible light having a wavelength that can be visually recognized by the user, specifically, a wavelength of about 360 nm to 830 nm.
The wavelength of the light emitted by the irradiator is preferably such that the reflected light reflected on the vehicle outer panel or the road surface is in the range of blue-green to green, that is, in the range of 500 to 570 nm. Since the light in this range is excellent in daytime visibility, if the reflected light on the vehicle outer panel is in this range, the sign of the light by the irradiation device can be visually recognized by the user with high reliability even in the daytime.
Further, when the irradiating device simply illuminates the road surface, it is preferable that the light emitted by the irradiating device has a wavelength such that the reflected light reflected on the road surface becomes white. Specifically, the light is preferably a mixture of two or more wavelengths of the above-mentioned visible light.

The light source of the irradiation device is not particularly limited as long as it can emit visible light in the above range, and halogen lamps, LED lamps, and the like can be exemplified.

The light source of the irradiation device may be one or a plurality of light sources. For example, when the irradiator irradiates the road surface in addition to the vehicle outer panel, the irradiator may have a plurality of light sources for irradiating each of these locations independently, or a plurality of these with one light source. You may irradiate the place of.
When the irradiation device has a plurality of light sources and the irradiation device irradiates a plurality of places, the irradiation device may include a plurality of irradiation paths in order to irradiate the plurality of places.

The amount of light of the irradiation device is not particularly limited as long as it can display a sign of light having a brightness that can be visually recognized by the user on the outer panel of the vehicle.
To give a specific example, the amount of light of the irradiation device is such that the illuminance on the outer panel of the vehicle is in the range of 1000 lux to 30,000 lux, in the range of 1200 lux to 1800 lux, in the range of 1350 lux to 1650 lux, or from 10,000 lux. The amount of light is preferably within the range of 20000 lux.

When the irradiator irradiates the road surface in addition to the vehicle outer panel, the amount of light of the irradiator that irradiates the road surface is such that the illuminance on the road surface is in the range of 200 lux to 800 lux, in the range of 300 lux to 700 lux, or 400 lux. The amount of light is preferably within the range of about 600 lux. As described above, when the road surface is illuminated by the irradiation device at night or in the rain, the amount of light of the irradiation device is such that the illuminance on the road surface is within the range of 5 lux to 300 lux and within the range of 10 lux to 100 lux. Alternatively, the amount of light is preferably in the range of 10 lux to 50 lux.

Further, when the vehicle lamp unit of the present invention has a licensed lamp, the light color of the light source of the licensed lamp is preferably white.
Further, the amount of light of the light source of the license lamp is preferably such that the number can be clearly seen even from about 20 m behind the vehicle. Specifically, the light amount is preferably a light amount such that the illuminance on the license plate is 8 lux or more, and more preferably 10 lux or more.

Further, in order to appropriately and appropriately display the sign on the outer panel of the vehicle, it is also possible to provide a display unit suitable for displaying the sign of light on the portion of the outer panel of the vehicle irradiated by the irradiation device.
For example, if the display unit has a satin-finished uneven shape, it is possible to suppress the reflection of external light on the display unit and clearly display the sign of the light emitted by the irradiation device on the display unit. In this case, the vehicle lamp unit of the present invention may include the display unit in addition to the sensor and the irradiation device.

The timing at which the irradiation device starts irradiation may be appropriately set according to the shape and specifications of the vehicle equipped with the vehicle lamp unit of the present invention, the usage status of the user, and the like. For example, it is preferable that the irradiation device starts irradiation when a user holding a smart key approaches the back door of the vehicle to a distance of about 80 cm to 100 cm.

The timing at which the irradiation device stops irradiation may also be appropriately set, but for example, it is preferable to stop irradiation when the back door is opened. Further, it is preferable to stop the irradiation of the irradiation device when the sensor does not detect the user's operation even after a predetermined time elapses after the start of irradiation. The predetermined time is preferably in the range of 10 seconds to 1 minute, and for example, 30 seconds can be exemplified.

In addition, the control unit that controls the operation of the vehicle lamp unit of the present invention may also serve as an ECU (Electronic Control Unit) of the vehicle, or may be dedicated to the vehicle lamp unit of the present invention. The control unit may be provided separately from the vehicle lamp unit of the present invention, or may form a part of the vehicle lamp unit of the present invention.

Hereinafter, the vehicle lamp unit of the present invention will be described with reference to specific examples.

(Example 1)
The vehicle lamp unit of the first embodiment is provided with a kick sensor as a sensor, and also has a function as a license lamp in which the irradiation unit irradiates the license plate.
An explanatory diagram schematically showing the state in which the vehicle lamp unit of the first embodiment is mounted on the vehicle is shown in FIG. 1, and the sign irradiated on the outer panel of the vehicle by the irradiation device in the vehicle lamp of the first embodiment is schematically shown. An explanatory diagram is shown in FIG. 2, an explanatory diagram schematically showing the vehicle lamp unit of the first embodiment is shown in FIG. 3, and an explanatory view schematically explaining a cross section of the vehicle lamp unit of the first embodiment through an irradiation device. The figure is shown in FIG.
Hereinafter, the terms "upper, lower, left, right, front, and rear" refer to the upper, lower, left, right, front, and rear shown in each figure. The vertical direction coincides with the vertical direction, the front-rear direction coincides with the vehicle traveling direction, and the left-right direction coincides with the vehicle width direction.

The vehicle lamp unit 1 of the first embodiment includes a kick sensor 4 and an irradiation unit 3. As shown in FIG. 1, the kick sensor 4 in the vehicle lamp unit 1 of the first embodiment is mounted inside the rear bumper 95 in the vehicle 90.
The irradiation unit 3 is separate from the kick sensor 4. The irradiation unit 3 has an irradiation device 30 and a license lamp 2 (see FIG. 3), and is mounted inside the back door 91 together with the handle mechanism 92 of the back door 91 in the vehicle 90, and has a rear bumper 95, a road surface 96, and a license plate. Irradiate 93. The vehicle outer plate of the vehicle lamp unit 1 of the first embodiment is a rear bumper 95, and the irradiation device 30 also irradiates the road surface 96 in addition to the rear bumper 95. In addition, a lock switch 35 for the back door 91 (see FIG. 3) is integrated with the vehicle lamp unit 1 of the first embodiment.

The irradiation unit 3 in the vehicle lamp unit 1 of the first embodiment is integrated with the handle mechanism 92 of the back door 91 in the vehicle 90. The handle mechanism 92 is mounted below and inside the back door 91 shown in FIG. More specifically, the license plate 93 is arranged below the back door 91, and the vehicle lamp unit 1 is arranged above the license plate 93 together with the handle mechanism 92 of the back door 91.

As shown in FIG. 3, the irradiation unit 3 has a license lamp 2 and an irradiation device 30. The irradiation device 30 is arranged to the right of the license lamp 2 and is integrated with the license lamp 2. The irradiation device 30 is arranged inside a housing 39, which is also called an outer lens. The irradiation device 30 includes an irradiation housing 32, an LED lamp 31, a design lens 33, and a first lens 36.

The design lens 33 is integrally provided at the rear end of the housing 39 and is arranged on the right side of the knob 92k of the handle mechanism 92. The LED lamp 31 is housed in the front end portion of the housing 39.

The irradiation device 30 irradiates both the upper surface of the vehicle outer panel, that is, the rear bumper 95 shown in FIG. 1 and the road surface 96, and displays a sign (80, 81) described later on each of them.
As shown in FIG. 4, the first lens 36 is located at the tip of the irradiation housing 32, that is, at the rear and lower ends, and is arranged on the front side of the LED lamp 31 in the irradiation direction. A design lens 33 is arranged further on the irradiation direction destination side of the first lens 36. A filter (not shown) is provided on the upstream side of the optical path of the design lens 33. The filter has a mask portion (not shown) having a shape corresponding to the sign 80 displayed on the upper surface of the rear bumper 95 and a shape corresponding to the sign 81 represented on the road surface 96. As a result, the light emitted by the LED lamp 31 and transmitted through the filter displays the signs 80 and 81 of the predetermined design as shown in FIG.

As shown in FIG. 3, the license lamp 2 is independent of the irradiation device 30 and is controlled independently of the irradiation device 30. Therefore, the irradiation of the rear bumper 95 and the road surface 96 by the irradiation unit 3 and the irradiation of the license plate 93 by the license lamp 2 are performed separately.

The vehicle lamp unit 1 of the first embodiment is connected to an ECU (not shown) of the vehicle 90, and the operation is controlled by the ECU.
The operation of the vehicle lamp unit 1 of the first embodiment will be described below.

When a user with a smart key approaches a stopped or parked vehicle 90, the key sensor (not shown) of the vehicle 90 detects this, and the ECU activates the vehicle lamp unit 1.

Specifically, the LED lamp 31 is turned on, and the irradiation device 30 irradiates the upper surface of the rear bumper 95 and the road surface 96 with light. Further, the kick sensor 4 starts sensing, that is, transmission and reception of ultrasonic waves.
At this time, the LED lamp 31 in the vehicle lamp unit 1 of the first embodiment glows blue-green. Therefore, the light emitted by the irradiation device 30 is easily visible to the user even in fine weather.

Here, in the vehicle lamp unit 1 of the first embodiment, the focus of the irradiation device 30 is aligned with the upper surface of the rear bumper 95. Therefore, as shown in FIG. 2, a clear light sign including an arrow-shaped design and characters is displayed on the upper surface of the rear bumper 95, and the road surface 96 is compared with the sign 80 displayed on the rear bumper 95. A slightly unclear sign 81 is displayed. In the vehicle lamp unit 1 of the first embodiment, the sign 80 displayed on the upper surface of the rear bumper 95 and the sign 81 displayed on the road surface 96 have different designs.

The detection range of the kick sensor 4 in the vehicle lamp unit 1 of the first embodiment is between the sign 80 displayed on the upper surface of the rear bumper 95 and the sign 81 displayed on the road surface 96.
Therefore, when the user moves his / her foot below the sign 80 displayed on the rear bumper 95 and above the sign 81 displayed on the road surface 96 in order to open the back door 91, the kick sensor 4 detects this. Then, based on the detection result of the kick sensor 4, the ECU opens and drives the back door 91, and the back door 91 is opened. At this time, the ECU stops the irradiation of light by the irradiation device 30 and the sensing by the kick sensor 4.

Even if the kick sensor 4 does not detect the user's operation 30 seconds after the ECU activates the vehicle lamp unit 1, the ECU irradiates the light by the irradiation device 30 and the kick sensor 4 is used. Stop sensing.

As described above, the vehicle lamp unit 1 of the first embodiment includes a license lamp 2. The license lamp 2 operates independently of the irradiation device 30 and the kick sensor 4.
The ECU activates the license lamp 2 when the accessory switch (not shown) of the vehicle 90 is turned on in an environment where the amount of light in the outside world is low, for example, at night. At this time, the license lamp 2 irradiates the license plate 93 with white light.

In the vehicle lamp unit 1 of the first embodiment, the irradiation device 30 irradiates the upper surface of the rear bumper 95, which is the outer panel of the vehicle, to display the light sign 80. As a result, the user can easily visually grasp the detection range of the kick sensor 4, that is, the position where the operation should be performed. That is, according to the vehicle lamp unit 1 of the first embodiment, the detection range of the kick sensor 4 can be easily perceived by the user, and by extension, the user can appropriately support the opening operation of the back door 91.

Further, in the vehicle lamp unit 1 of the first embodiment, the upper surface of the rear bumper 95 and the road surface 96 are irradiated by the irradiation device 30, and light signs 80 and 81 indicating the detection range of the kick sensor 4 are displayed on each of them. .. As a result, the user can easily grasp the detection range of the kick sensor 4.

Further, the vehicle lamp unit 1 of the first embodiment has a license lamp 2 in addition to the irradiation device 30 for irradiating the rear bumper 95 and the road surface 96 to display the signs 80 and 81. The irradiation device 30 and the license lamp 2 are integrated. As a result, the vehicle lamp unit 1 of the first embodiment can be made smaller and lighter, and is suitable as an in-vehicle lamp unit.

(Example 2)
The vehicle lamp unit of the second embodiment is substantially the same as the vehicle lamp unit of the first embodiment except for the structure of the irradiation unit. Therefore, the vehicle lamp unit of the second embodiment will be described below, focusing on the differences from the vehicle lamp unit of the first embodiment.
FIG. 5 is an explanatory diagram schematically showing a sign that the irradiation device in the vehicle lamp unit of the second embodiment irradiates the vehicle outer panel, and FIG. 6 is an explanatory diagram schematically showing the vehicle lamp unit of the second embodiment. 8 and 9 show an explanatory view schematically illustrating a cross section of the vehicle lamp unit of the second embodiment through the irradiation device, which is shown in FIG. 7. 8 is a cross section at the AA position in FIG. 7, and FIG. 9 is a cross section at the BB position in FIG. 7.
Hereinafter, the terms "upper, lower, left, right, front, and rear" refer to the upper, lower, left, right, front, and rear shown in each figure. The vertical direction coincides with the vertical direction, the front-rear direction coincides with the vehicle traveling direction, and the left-right direction coincides with the vehicle width direction.

The irradiation unit 3 in the vehicle lamp unit 1 of the second embodiment is significantly different from the irradiation unit 3 in the vehicle lamp unit 1 of the first embodiment, particularly in the irradiation device 30.
As shown in FIGS. 6 to 9, the irradiation device 30 in the vehicle lamp unit 1 of the second embodiment has two LED lamps, that is, a first LED lamp 31a and a second LED lamp 31b, and two lenses, that is, a first lens. It includes a lens 36a and a second lens 36b.

As shown in FIGS. 7 to 9, the first LED lamp 31a and the second LED lamp 31b are arranged on the left and right. The first LED lamp 31a and the second LED lamp 31b emit white light.

As shown in FIGS. 8 and 9, the first lens 36a is arranged on the irradiation direction destination side of the first LED lamp 31a and the second LED lamp 31b. As shown in FIGS. 7 and 8, the second lens 36b is arranged only on the irradiation direction destination side of the first LED lamp 31a that has passed through the first lens 36. That is, in the vehicle lamp unit 1 of the second embodiment, the irradiation device 30 includes a system of the first LED lamp 31a → the first lens 36a → the second lens 36b and a system of the second LED lamp 31b → the first lens 36a. It has a system irradiation path. Of these two irradiation routes, the former is referred to as the first system and the latter is referred to as the second system.

As shown in FIG. 8, the irradiation path of the first system has two lenses, that is, a first lens 36a and a second lens 36b. Therefore, in the irradiation path of the first system, the light of the LED lamp 31a is refracted relatively greatly. Therefore, as shown in FIG. 5, it can be said that the irradiation path of the first system is suitable for irradiating the road surface 96 located at a position away from the irradiation device 30 and displaying the sign 81.

In the second embodiment, the amount of light of the first LED lamp 31a is such that the illuminance of the road surface at night is about 30 lux and the user's feet can be illuminated. In Example 2, the sign 81 is displayed by the irradiation path of the first system, but the irradiation path of the first system may simply illuminate the road surface 96.

As shown in FIG. 9, the irradiation path of the second system has one lens, that is, the first lens 36a, and the light of the LED lamp 31b is not refracted so much in the irradiation path of the second system. Therefore, as shown in FIG. 5, the irradiation path of the second system can be said to be suitable for irradiating the upper surface of the rear bumper 95 located near the irradiation device 30 and displaying the sign 80.

As described above, the irradiation device 30 in the vehicle lamp unit of the second embodiment has two irradiation paths having different numbers of lenses. Thereby, the vehicle lamp unit 1 of the second embodiment is suitable for irradiating a place where the position with respect to the irradiation device is different from the upper surface of the rear bumper 95, that is, the road surface 96, in addition to the vehicle outer plate, that is, the upper surface of the rear bumper 95. Get good.

The present invention is not limited to the embodiment described above and shown in the drawings, and can be appropriately modified and implemented without departing from the gist. In addition, each component shown in the present specification including the embodiment can be arbitrarily extracted and combined.
