Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATIONS The present invention relates to a cornering lamp that illuminates both sites of a vehicle when cornering or parking the vehicle.

In addition to the headlamp, which is the main source of forward illumination, the moonlight device installed on conventional technology vehicles uses various auxiliary lamps such as fog lamps, backup lamps, and cornering lamps.If we focus on the cornering lamps,
It has the function of increasing safety by illuminating the side of the vehicle using the cornering lamp when checking the road shoulder on mountain roads that require sharp turns or turning corners, and when entering and exiting parking lots or entering the garage. There is.

Normally, the above-mentioned cornering lamps are fixed to the corners on both sides of the front of the vehicle. For example, as shown in FIG. The relay 7 interposed between the turn signal switch 5 and the turn signal switch 5 is turned on, and the operation piece 5a of the turn signal switch 5 is connected to the left and right contacts 5b.
, 5c, the left cornering lamp 9 or the right cornering lamp 1
1 is selectively lit. B is a battery terminal, and R is a relay driving resistor.

That is, the cornering lamps 9 and 11 also serve as turning lamps, and by turning on either one when the vehicle turns right or left or changes lanes, 1. It is possible to illuminate the sides of the vehicle in the cornering direction.

Problems to be Solved by the Invention However, in such conventional vehicle cornering lamps, the cornering lamps were fixed to the corners on both sides of the front of the vehicle body, so the irradiation position of the cornering lamps was limited to within a specific range. However, there is a problem in that it may not always be possible to illuminate the position that the driver wants to see depending on the driving conditions of the vehicle.

For example, the driver's line of sight is generally affected by the vehicle speed; when driving at low speed, the driver's line of sight is at a short distance ahead, but as the vehicle speed increases, the driver's line of sight becomes farther ahead. Transition. Therefore, when cornering at a vehicle speed of a certain level or higher, it is desirable that the irradiation position of the cornering lamp be shifted to a position somewhat distant from the vehicle rather than near the side of the vehicle.

On the other hand, in the conventional example described above, the irradiation positions of the left and right cornering lamps 9.11 cannot be changed, so
The irradiation position of the cornering lamp 9.11 relative to the road surface remains unchanged, and there is a problem in that it cannot meet the driver's demands as described above.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a device that can solve the problems that conventional vehicle cornering lamps have and can appropriately change the irradiation position of a cornering lamp depending on the driving condition of the vehicle. This is the purpose.

Means for Solving the Problems In order to achieve the above object, the present invention first provides a cornering lamp installed at the left and right corners of the front of a vehicle, which comprises a back cover fixed to the vehicle body. ,
A cornering lamp for a vehicle comprising a front glass disposed in contact with the back cover, and a lamp body disposed in a space formed between the back cover and the front glass, wherein one end of the back cover A pivot part is provided between the back cover and one end of the lamp body to allow the lamp body to rotate at least in the vertical direction, and a pivot part is provided between the other end of the back cover and the other end of the lamp body. According to a second aspect of the present invention, the drive mechanism includes circuit means for vertically adjusting the irradiation angle of the lamp body in response to the vehicle speed. This is the structure of the vehicle cornering lamp provided.

According to the structure of claim I, when the driving mechanism of the lamp body is operated, the lamp body rotates about the pivoting portion, and the light beam emitted from the light source within the lamp body is directed diagonally upward and downward. be variably adjusted in the direction. Therefore, the side visibility distance of the cornering lamps can be changed as appropriate to illuminate the position that the driver wants to see.

Furthermore, according to the structure of the second term, since the y (angle of rays) of the lamp body is adjusted in response to the vehicle speed, for example, when driving at low speed, the side view distance due to the cornering lamp is small,
As the vehicle speed increases, the side visibility distance can be made to gradually extend further away.

EMBODIMENTS Various embodiments of the vehicle cornering lamp according to the present invention will be described below with reference to the drawings.

In the figure, 15 is a back cover, +7 is a front glass, The back cover 15 is fixed to the left and right corners of the front of the vehicle. Further, the front glass 17 is disposed in contact with the back cover 15 and is bent in advance to match the shape of the corner portion of the vehicle. A space 4 is formed between the back cover 15 and the front glass 17.

A guide strip 19 is protruded from the rear of the back cover 15, and an electric actuator 21 is disposed inside the guide strip 19. This actuator 21
constitutes a driving mechanism of the lamp body, which will be described later, and a lead wire 23 led out from the actuator 21.
．． 23 is a simple guide! It passes through a seal portion tt25 fitted to the flange portion +9a of No. 9 and is connected to a drive source (not shown).

Reference numeral 27 denotes a lamp body, and the lamp body 27 is disposed within the space 4, and a light ji 29 is disposed approximately at the center thereof.

A base 3I having a recessed portion 31a is fixed to the lower rear surface of the lamp body 27, and a base 3I having a recessed portion 31a is formed integrally with the tip of a drive rod 21a that protrudes from the actuator 2I in the front Ff1 direction. One spherical body 21b is combined.

Furthermore, a recessed portion 33 is provided above the inner surface of the back cover 15.
A support bracket 33 having a shape is integrally formed, and a base 1135a of a shaft body 35 that protrudes in the rear RR direction is fixed to the upper rear surface of the lamp body 27. A sphere 35b formed in the above-mentioned shape is fitted into the recess 1133a. The support bracket 33 and the sphere 35b constitute a pivot portion 20 that rotates the lamp body 27 at least in the vertical direction.

Note that the cornering lamp 12 described above shows only one side of the lamp configuration installed at both corners of the front of the vehicle, but even for the cornering lamp on the other side, the shape of the front glass 17 is symmetrical. Other than that, they have the same configuration.

According to the configuration of the cornering lamp 12, when the drive rod 21a protruding from the actuator 2I constituting the drive mechanism of the lamp body 27 is driven in a substantially horizontal direction as shown by arrow A in FIG. The main body 27 has a pivot portion 20. That is, it rotates in the direction shown by arrow B in the figure with the sphere 35b formed at the tip of the shaft body 35 as the rotation center. Therefore, the driving force of the actuator 21 causes the light source 29 to
The substantially horizontal light ray a emitted from the light beam A can be variably adjusted diagonally up and down like the light beam C or the light beam C.

FIG. 3 shows an example of a first driving circuit for the cornering lamp 12, and numeral 1 in the figure is a lighting switch placed in the vehicle interior, and one end of the lighting switch 1 is connected to a battery 39. ing. 3 is an ignition, 41 is an amplifier, 43 is a vehicle speed sensor, and this vehicle speed sensor 43
A relay 7 that is turned on and off by operating the lighting switch 1 is arranged between the light switch 1 and the amplifier 41. R is a relay driving resistance.

The output of the amplifier 4I is manually supplied to a controller 45, and a lead 82 led out from this controller 45
3.23 are connected to actuator 21c and actuator 21d, respectively. This actuator 21
c and 21d correspond to the actuators 21 in FIGS. 1 and 12 of nZi, respectively.

12a is the cornering lamp on the left side of the front of the vehicle.

+2b is a cornering lamp of the same type, and the cornering lamps 12a and 12b are actuated by the actuator 2 based on the drive mode shown in FIGS. 1 and 2.
1c and the driving force of the actuator 21d, the light rays a, ib, or C are variably adjusted diagonally upward and downward in a substantially horizontal direction emitted from the light source of each lamp.

Reference numeral 5 denotes a turn signal switch for selecting either one of the cornering lamps +2a and 12b, one end of which is connected to the ignition 3, and the operation piece 5a of the turn signal switch 5 is connected to the left and right. By contacting either the contacts 5b or 5c, the left cornering lamp +2a or the right cornering lamp 12b is selectively turned on.

According to the first example of the drive circuit, the vehicle speed signal detected by the vehicle speed sensor 43 is input to the amplifier 41 along with the ignition 3, and the output of the amplifier 41 is input to the controller 45.

The controller 45 stores in advance the relative relationship between vehicle speed (Km/H) and side visibility distance (m) as shown in graph (■) in Fig. 4 as a control map, and controls left cornering based on this control map. The actuators 21c and 21d are driven and controlled so that the irradiation angles of the lamp 12a and the right cornering lamp I2b match the lateral visibility distance of graph (2). That is, according to graph ■,
The lateral visibility distance is set to gradually increase as the vehicle speed increases.

In other words, the actuator 2 constituting the drive mechanism,
A circuit means is provided for vertically adjusting the irradiation angle of the lamp body 27 in response to the vehicle speed.

Therefore, when the vehicle turns right or left or changes lanes, the left and right cornering lamps 12a,
The irradiation angle of 12b is changed accordingly, and the cornering lamp on the side of the vehicle! The irradiation position of 2a and 12b can be set within the range desired by the driver.

FIG. 5 shows a second example of the driving circuit for the cornering lamp 12, the basic configuration of which is the same as the first example of the driving circuit, and is indicated by the same reference numerals. .

This circuit example shows a simplified version of the first drive circuit example, and specifically, a transistor 47 is interposed between the vehicle speed sensor 43 and the relay 7, and the transistor 47 controls the ignition 3 and the relay 7. The on/off state between the relays 7 is controlled. Therefore, in this example, the controller 45 is omitted.

According to this configuration, the transistor 47 is not turned on when the vehicle speed signal detected by the vehicle speed sensor 43 is below a predetermined value, so that when the lighting switch 1 is turned on, the ignition 3 and the turning null switch 5 are not connected. While the side visibility distance remains small, when the vehicle speed signal reaches a predetermined value or more, the transistor 47
becomes conductive, and therefore, by operating the operating piece 5a of the turning null switch 5, the actuator 21 is turned on.
Either one of c and 21d is driven.

In other words, whether or not the actuators 2jc and 21d are driven is determined by the threshold value of the transistor 47. For example, as shown in FIG.
If the above threshold value is set to correspond to 40 km/h (km/h), the side visibility distance will be small (approximately 10 m) when the vehicle speed is below 40 km/h.
(Km/H), actuator 21c is immediately activated.
, 21d is driven so that the side visibility distance of the vehicle is a certain length,
According to Figure 6, it will be extended by about 35m. In other words, the vehicle speed is 4
An operation mode is obtained in which the side visibility distance is changed in stages starting from 0 (Km/H).

Figure 7 shows the above cornering lamp! 2 shows a third example of the drive circuit in FIG.

This circuit example shows a case in which the second drive circuit example is further simplified, and specifically, the actuators 21c and 21d are removed from the second drive circuit example, and the relay 7 is replaced with a receptacle-closed type. Use things.

According to this circuit example, when the vehicle speed signal detected by the vehicle speed sensor 43 is below a predetermined value, the turning null switch 5
The cornering lamps 12a and 12b are selectively turned on when the vehicle speed signal exceeds a predetermined value. 2a.

An operating mode is obtained in which +2b is not lit.

That is, in general, the cornering lamps 12a and 12b are not required when the vehicle is running at medium to high speeds, and therefore, with this circuit configuration, power consumption can be saved by turning off the cornering lamps 12a and 12b at a predetermined vehicle speed or higher. Effect can be obtained.

Effects of the Invention As explained in detail above, according to the cornering lamp for a vehicle according to the present invention, the lamp body is pivotally connected between one end of the back cover and one end of the lamp body so that the lamp body can freely rotate at least in the vertical direction. A drive mechanism is provided between the other end of the back cover and the other end of the lamp body to rotate the lamp body around the pivot point, so that the following effects can be achieved. effect is brought about.

That is, the lamp body is rotated about the pivot point by the drive mechanism of the lamp body, and the light beam emitted from the light source within the lamp body is variably adjusted diagonally up and down. It becomes possible to change the visibility distance as appropriate. Therefore, the irradiation position of the cornering lamp is no longer limited to a specific range, and it is possible to irradiate the position that the driver wants to visually recognize according to the driving conditions of the vehicle.

Furthermore, according to the configuration of claim 2, the irradiation angle of the lamp body is adjusted in response to the vehicle speed, so that, for example, when driving at low speed, the lateral visibility distance due to the cornering lamp is reduced, and as the vehicle speed increases, the lateral visibility distance is decreased. It is now possible to gradually extend the irradiation distance further, and it is possible to select the irradiation position that is most suitable for the vehicle speed.
