Description

Far and near light control device

The present invention mainly relates to the technical field of a solenoid valve controlling far and near lights. In particular, the solenoid valve has the progressive advantages of labor-saving operation, shortened stroke and reduced volume.

Click, the previous technology is as shown in my country's M438415 "distance and near light control device improvement" and M575403 "far and near light switch device", but the two patents have the following problems to be overcome:

1. The light-shielding plate and solenoid valve of the previous two patents are both installed on the fixed plate, so when the solenoid valve drives the light-shielding plate to swing, it cannot fully enlarge the force arm of the light-shielding plate, causing the solenoid valve to drive the light-shielding plate hard The problem, under long-term operation, will have a negative impact on the service life and power consumption of the solenoid valve.

2. Whether the solenoid valve is energized through the coil to make the valve shaft have a reciprocating stroke, and then to control the far light or near light use state of the light shielding plate, because the two patents cannot further reduce the valve shaft of the solenoid valve Therefore, there is still room for improvement in the volume of solenoid valve, purchase cost and limited installation space.

In view of this, the creator of this invention has developed the invention based on years of professional experience and experience, through continuous ideas, innovations and research.

The main content of the present invention is to provide a far and near light control device, which The content includes: a lamp holder; a light-shielding plate, which is pivotally connected to the lamp holder by a support shaft and is provided with a main hole parallel to the support shaft; a fixing plate installed on the lamp holder; a solenoid valve provided on the fixing plate, It defines a reciprocating stroke along the axial direction of the valve shaft; and a detent that can be linked by the valve shaft, which defines a hinge section that is pivotally connected to the main hole, a crank extending directly from the middle ends of the hinge section, and a The rocker arms extend symmetrically from the left and right ends of the crank, so that the rocker arm is coupled to the valve shaft, and further defines the length of the crank along the axis of the valve shaft, which is greater than the length of the rocker arm along the radial direction of the valve shaft, and controls The hinged section of the actuator is kept between the valve shaft and the supporting shaft, so that the valve shaft can switch the low beam or high beam of the lamp holder when the rocker arm and the light shield are linked.

With the above-mentioned overall structural features, the force arm of the solenoid valve driving the light shield can be fully enlarged. Therefore, the solenoid valve has the characteristics of labor-saving operation and prolonged service life. Furthermore, the special shape of the actuator can relatively shorten the solenoid The valve stroke effectively reduces the volume and manufacturing cost of the solenoid valve and is easy to install. Therefore, the present invention clearly can greatly improve the shortcomings of the previous two patents.

As shown in Figures 1 to 4, the present invention at least includes: a lamp holder 10 with a main light source 11 installed on the central axis of the top surface, and a supplementary light source 13 installed in front of the main light source 11, the lamp The base 10 is also provided with a main light driving chip 111 matching the main light source 11, a main light reflector 12, and a complementary light driving chip 131 matching the main light source 13 and a light reflector 14 are assembled together. The light-driving chip 111 and the light-filling drive chip 131 are provided with at least three pieces in the present invention. In particular, the light-filling lamp source 13 and the light-filling reflector 14 are mainly used to make up for the lack of light source measurement in the center of the distance lamp. The front end of 10 is more symmetrically provided with a fixing portion 15, and the inner sides of the two fixing portions 15 are respectively provided with fork rods 16 protruding from the front end, so that a fork groove 17 with an opening facing forward is defined between the two fork rods 16; one is installed in the lamp holder The fixing piece 20 of 10 defines a symmetrical first surface 21 and a second surface 22, and then the first surface 21 abuts on the two fixing portions 15 through bolts (not shown in the figure) or other elements. At this time, the fixing piece 20 is across the fork groove 17, and the fixing piece 20 is further provided with a coupling portion 23 at the center of the fork groove 17. A light shielding plate 30 installed in the range of the fork groove 17 is opposite to the shaft 31. It is pivotally connected to the front edge of the fork rod 16 to enable the shading plate 30 to swing up and down within the range of the fork groove 17 with the support shaft 31 as a fulcrum, thereby controlling the lamp holder 1 0 low beam or high beam; the left and right sides of the shading plate 30 are respectively provided with pivot seats 32 facing the rear, and the two pivot seats 32 are held in the fork groove 17 and run through the parallel pivots 31 Main hole 33; a detent member 40, which is formed by bending a round rod, the left and right ends of the detent member 40 have hinged sections 41 pivotally connected to the main hole 33, and in the middle of the two hinged sections 41 A U-shaped crank 42 extends directly downward at both ends, and the left and right ends of the middle section of the bottom end of the crank 42 are symmetrical. In addition, a U-shaped rocker arm 43 protrudes horizontally and rearwardly. This rocker arm 43 is suspended below the lamp holder 10 so that the crank 42 and When the rocker arm 43 swings up and down, it can drive the shading plate 30 to swing up and down around the supporting shaft 31 through the hinged section 41. It is specifically explained here that the rocker arm 43 cannot interfere with the lamp holder 10 during the swing process. It is shown that the crank 42 and the rocker arm 43 are arranged in a different plane, and form an included angle θ of approximately ninety degrees, and the length defined by the downward extension of the crank 42 is further controlled, which is greater than that of the rocker arm 43 protruding backwards. Defined length; and a solenoid valve 50, which has a valve body 51 fixed on the connecting portion 23 of the fixing plate 20, the valve body 51 is located on the first surface 21 of the fixing plate 20, and an axially longitudinally arranged valve is installed The shaft 52 defines a reciprocating stroke along the axis of the valve shaft 52. Specifically, when the internal coil of the valve body 51 is energized, the valve shaft 52 can be driven to overcome the preload of a spring 53 to move down by a stroke, and the valve The top edge of the shaft 52 is provided with a ring groove 521 for coupling with the rocker arm 43. The left and right sides of the U-shaped rocker arm 43 are symmetrically confined in the ring groove 521, and the size of the control ring groove 521 is sufficient to provide the rocker arm 43 front and rear. Move and slightly swing up and down, so that the valve shaft 52 can reciprocate longitudinally to actuate the crank 42 and the rocker arm 43 to swing up and down, so that the hinge section 41 is sufficient to drive the light shielding plate 30 to swing in a curved arc around the support shaft 31. To Switching the low beam or high beam of the lamp holder 10, as shown in Figure 3, when the solenoid valve 50 does not energize the valve shaft 52, the spring 53 keeps the valve shaft 52 at the top dead center position, and the actuator 40 is The light shielding plate 30 can be linked to block the fill light source 13 guided by the fill light reflector 14. As for the main light reflector 12, the main light source 11 can be directed obliquely forward. At this time, it is in the low beam state. However, when the solenoid valve 50 excites the valve shaft 52 to overcome the preload of the spring 53 and moves down to the bottom dead center, as shown in Fig. 4, the detent 40 can control the shading plate 30 to move down around the support shaft 31 Swing to a fixed point, so that the shading plate 30 cannot block the fill light source 13 guided by the fill light reflector 14 and illuminate it horizontally, and then switch to the high beam use state.

It is particularly stated here that the shape of the crank 42 and the rocker arm 43 of the actuator 40 shown in Figures 1 to 4 can also be replaced with a curved surface or other appropriate shapes. It is only necessary to control the crank 42 to be defined along the axis of the valve shaft 52. The length should be greater than the length defined by the rocker arm 43 along the radial direction of the valve shaft 52. In this way, the efficiency of the up and down swing of the light shielding plate 30 in conjunction with the valve shaft 52 can be enlarged. Compared with the previous two patents, it can be compared. The shortening of the reciprocating stroke of the valve shaft 52 belongs to the present invention.

Please refer to Figures 5 to 8, which further illustrate that the valve shaft 52 of the solenoid valve 50 of the present invention can be installed horizontally or horizontally in the axial direction. For the same reason, the solenoid valve 50 can also be installed on the fixing plate in different angles. 20; in terms of Figures 5 to 8, the fixing piece 20 is provided with a joint 23 passing through the first surface 21 and the second surface 22, a movable groove 24, and a folding edge 25 protruding from the second surface 22 is extended , And the valve body 51 of the solenoid valve 50 is fixed on the flange 25, so that the valve body 51 is located on the second surface 22 of the fixing plate 20, and an axially and transversely arranged valve shaft 52 is installed. Part 23, and the valve shaft 52 is located on the end edge of the first surface 21, there is a ring groove 521, as for the left and right ends of the detent 40 The edge has a hinge section 41 that can be pivotally connected to the main hole, and a U-shaped crank 42 extends horizontally and rearwardly between the two hinge sections 41. The crank 42 passes through the movable groove 24 of the fixed piece 20, and the rear end of the crank 42 is directed toward A U-shaped rocker arm 43 extends downward. The left and right sides of the rocker arm 43 are symmetrically confined to the ring groove 521. This configuration can achieve the effects shown in Figures 1 to 4.

Please cooperate with Figures 1 to 4 to see that the present invention has at least the following advancements:

1. In the present invention, the light-shielding plate 30 is pivotally connected to the lamp holder 10 by the support shaft 31, and the hinge section 41 is a structural feature that is maintained between the valve shaft 52 and the support shaft 31, which can indeed fully increase the drive of the solenoid valve 50 The force applying arm of the light shielding plate 30 enables the solenoid valve 50 to have the advantage of labor-saving operation, so that the service life and power consumption of the solenoid valve 50 can be better.

2. Since the length of the crank 42 along the axial direction of the valve shaft 52 of the actuator 40 of the present invention is much greater than the length defined by the rocker arm 43 along the radial direction of the valve shaft 52, the shape can greatly lift the valve shaft 52 The efficiency of the light-shielding plate 30 is linked, so that the reciprocating stroke of the valve shaft 52 can be effectively shortened, so that the volume and purchase cost of the solenoid valve 50 can be further reduced, and the effects of ease of installation can be achieved.

In summary, the present invention has indeed broken through the shortcomings of the previous two patents in the reform and disclosure of the two patents. It is a highly creative technical concept and should meet the requirements of a patent application and file an application in accordance with the law. However, the above is only one of the preferred embodiments of the present invention. When it cannot be used to limit the scope of implementation of the present invention, that is, all equal changes and modifications made in accordance with the scope of the patent application of the present invention should still belong to the present invention.
