Description

Technical Field

[0001] The present invention relates to the field of automotive lamps, and more particularly to an automotive headlamp with a ramp adaptive lighting function and its production equipment. Background Art

[0002] Automotive headlamps are devices installed on both sides of the front of an automobile for illuminating the road at night, also known as automotive headlights. Automotive headlamps mainly consist of components such as a plastic lamp housing, a plastic lamp cover, a light source, and a reflector.

[0003] Although existing automotive headlamps have the function of adjusting the irradiation direction, they often rely on the active adjustment of the user. Although matrix headlamps have rich adjustment functions, their costs are often relatively high, and they are more suitable for high-end models and do not have universal applicability. When a current automobile is going uphill, since light often travels in a straight line, it causes the situation on the slope to be difficult to be illuminated by the light before going uphill, resulting in a certain visual blind area, thus affecting driving safety. At the same time, the existing headlamp steering function of automobiles often requires changing the steering of the headlamp, and its response is often slow, making it difficult to meet the application requirements in reality.

[0004] At the same time, during the production of the front lamp cover of an automobile, a strengthening film needs to be plated on its surface to increase the stiffness and wear resistance of the lamp cover surface. The existing coating methods still largely use manual spraying. Such a method is difficult to ensure the uniformity of spraying during the spraying process. At the same time, due to the operator holding the lamp cover during the spraying process, some positions will be blocked and not sprayed due to the operator's problems during the operation, resulting in a decrease in the yield rate. Existing lamp cover spraying devices often only spray the outer end face of the lamp cover and cannot spray both the inner and outer end faces of the lamp cover in one working process. Summary of the Invention

[0005] In order to overcome the above technical problems, the present invention provides a headlamp with a ramp adaptive lighting function.

[0006] The object of the present invention can be achieved by the following technical solutions: An automotive headlamp with a ramp adaptive lighting function includes a mounting bracket. A front lamp cover is fixedly installed at the front end of the mounting bracket, and a condenser cover is fixedly installed at the rear end of the mounting bracket. A light source is fixedly installed at the middle position of the condenser cover. A radar detector is fixedly installed on the mounting bracket. The front lamp cover is processed into a relatively long cylindrical shape. An opaque material is sprayed on the side surface of the front lamp cover. A beam splitter is rotatably installed at the middle position of the front lamp cover, and the beam splitter is a lens capable of reflecting light.

[0007] The mounting bracket is used to mount the automotive headlamp on the vehicle. During the illumination of the automotive headlamp, the light source emits light, and the condenser cover will converge the light into a state of forward illumination and emit it from the front end of the front lamp cover. During the driving of the vehicle, the radar detection head will monitor the road conditions ahead. The radar detection head is a prior art and uses the lidar or millimeter-wave radar currently used on vehicles, which can effectively detect the terrain and obstacles. A small motor with a drive shaft fixedly connected to the beam splitter is integrated in the front lamp cover, and each beam splitter is driven by a small motor. This small motor can use the Sieg transmission micro motor, and its diameter can reach 8 mm, which is convenient for installation in the relatively narrow space of the condenser cover. When it is detected that the road condition ahead is an uphill road surface with a slope greater than 15 degrees, the radar detection head will notify the control terminal in the vehicle, and the control terminal will issue an instruction to make the drive shaft of the small motor in the front lamp cover drive the beam splitter to rotate, so that the beam splitter rotates 8 degrees. When the light hits the beam splitter (the material of the lenses forming the beam splitter is the same as that of the existing mirror), the light will be reflected on the beam splitter, thereby changing the propagation path of the light. The light source has a width of 5 mm, the width of the beam splitter is 20 mm, and the distance from the light source to the midpoint of the beam splitter is 50 mm. When the light of the light source irradiates the beam splitter, a light band between 15 degrees and 22 degrees will be formed, so as to illuminate the ramp. When driving on a flat road, the control terminal will issue an instruction to make the small motor drive the beam splitter to return to the normal position, and the light enters from the side of the beam splitter. The base material of the beam splitter is made of transparent glass and will not affect the propagation of the light. In the prior art, when changing the propagation path of the light, multiple light sources are often used. If this method still needs to ensure the directional propagation of the light, it will lead to a very complex shape structure of the lamp cover, thereby increasing the manufacturing cost, while the above technical solution will not cause the shape of the lamp cover to become complex.

[0008] The present invention also provides a production device for an automotive headlamp with a ramp adaptive lighting function. This production device is applicable to the above-mentioned automotive headlamp with a ramp adaptive lighting function and can ensure the uniformity of spraying during the process of spraying a strengthening film on the automotive front lamp cover, and can spray the inner and outer end faces of the lamp cover.

[0009] A production device for an automotive headlamp with a ramp adaptive lighting function, comprising: A fixed frame, with a driving roller rotatably mounted on each side of the fixed frame, and a driving pulley fixedly installed on each side of the driving roller; A conveyor belt, which is used to connect the two driving pulleys on the same side of the driving roller, and one conveyor belt is provided corresponding to the driving pulleys on both sides of the driving roller; A loading device, which is installed at the middle position between the two conveyor belts, and the loading devices are evenly distributed on the conveyor belts; Spraying device, the spraying device includes a spraying ring frame, the spraying ring frame is fixedly installed on the fixed frame, the spraying ring frame surrounds the upper section of the conveyor belt, and a spraying mechanism for spraying the front lamp cover is arranged on the spraying ring frame.

[0010] During the spraying operation of the automotive front lamp cover, the automotive front lamp cover is placed on the loading device. The driving roller is driven to rotate by the power source. While the driving roller rotates, it will drive the rotation of the driving belt pulley. The driving belt pulley drives the movement of the conveyor belt, and the conveyor belt drives the movement of the loading device. When the loading device drives the front lamp cover to the middle position of the spraying ring frame, the spraying mechanism will move in a circular motion along the spraying ring frame. During the circular motion of the spraying ring frame, the front lamp cover will be evenly sprayed. Compared with manual spraying by humans, the spraying effect is more uniform. Compared with existing equipment for spraying, since the spraying mechanism sprays around the front lamp cover, both the inner and outer sides of the front lamp cover can be evenly sprayed, thus achieving a better spraying effect.

[0011] Further scheme, the loading device includes a loading rod, a placement part for placing the front lamp cover is fixedly installed in the middle of the loading rod, the lower end of the placement part is hollowed out, and the left and right ends of the loading rod are fixedly installed on the conveyor belt.

[0012] When the front lamp cover is placed in the placement part of the loading mechanism, it can move along with the movement of the conveyor belt, and the structure of this loading device is very simple, not only with low cost but also very reliable and durable.

[0013] Further scheme, the loading device includes a loading erection rod, a loading part and a connecting mechanism. The loading part is arranged at the middle position between the two conveyor belts. A through hole for installing the front lamp cover is opened in the middle of the loading part. A loading erection rod is fixedly connected to each of the left and right sides of the loading part. Connecting mechanisms are fixedly installed on the conveyor belt corresponding to the front end and the rear end of the loading erection rod. The connecting mechanism includes a connecting cover and a connecting spring. The connecting cover is fixedly installed on the conveyor belt. The end of the connecting cover and the loading erection rod are fixedly connected by the connecting spring. A plurality of connecting springs are evenly arranged circumferentially around the end of the loading erection rod.

[0014] After long-term use, the conveyor belt will more or less deform. In order to reduce the phenomenon that it is difficult to place the front lamp cover flat during placement due to the deformation of the conveyor belt, the loading part is erected by a long loading rod, which can effectively inhibit the phenomenon that the position of the loading part is not correct when placing the lamp cover due to the deformation of a certain part of the conveyor belt. However, at this time, when the loading rod is conveyed to the driving pulley, the distance between two fixed points on the conveyor belt will change slightly. By connecting the loading erection rod and the connecting cover with a connecting spring, the end of the loading erection rod is allowed to displace in the connecting cover, so as to offset the above changes of the conveyor belt.

[0015] In a further solution, the spraying mechanism includes a spraying ring plate. Four rollers are rotatably connected to the spraying ring plate, and the four rollers are clamped on the spraying ring frame. A sliding plate is fixedly connected to the spraying ring plate. A sliding groove is formed in the sliding plate, and a slider is slidably connected in the sliding groove. A spraying rod is installed on the slider. A reciprocating ring is fixedly installed on the spraying ring frame, and a circulating wavy reciprocating groove is machined on the inner side of the reciprocating ring. The sliding plate is slidably connected to the reciprocating groove through a rod.

[0016] During the process that the spraying mechanism makes a circular motion around the spraying ring frame, by installing a motor on the spraying ring plate to drive the rotation of the rollers, the rollers drive the spraying mechanism to make a circular motion around the front lamp cover during rotation. The spraying mechanism integrated on the spraying rod is the same as that of the existing paint spraying gun, and receives high-pressure gas mixed with coating paint through a pipeline. At the same time, since it is difficult to ensure that the paint density at each spraying position is the same during the process of spraying paint by the existing spray gun, during the process that the spraying mechanism makes a circular motion around the spraying ring frame, the rod on the sliding plate will be slidably connected to the reciprocating groove, so that the spraying slider slides reciprocally along the sliding groove, and the spraying slider will drive the spraying rod to make a reciprocating motion at the same time. In this way, during the process of spraying the front lamp cover of the car, each area sprayed by the spraying rod can spray the front lamp cover, thereby improving the uniformity during the spraying process.

[0017] In a further solution, the spraying ring plate makes a reciprocating circular motion along the spraying ring frame.

[0018] Because the spraying mechanism is connected to the pipeline for transporting high-pressure gas mixed with paint, the above device can effectively prevent the phenomenon of entanglement.

[0019] In a further solution, a visual detection head is fixedly installed on the spraying ring plate.

[0020] By observing the position of the loading device through the visual detection head, when the loading device moves to the middle position of the spraying ring frame, a signal can be sent to the relevant control system to stop the rotation of the driving roller, and then the front lamp cover can be sprayed.

[0021] In a further solution, the spraying rod is slidably connected to the slider. A spring is sleeved on the spraying rod, and the spring is fixedly installed at one end of the spraying rod close to the reciprocating ring and on the sliding plate. A contact ring plate is fixedly installed inside the reciprocating ring. The contact ring plate is in sliding contact with the spraying rod, and the lower end of the contact ring plate protrudes upward.

[0022] Since the front lamp cover is concave, in order to achieve the same spraying effect when spraying the inner side of the front lamp cover as when spraying the outer side, the spraying rod slides along the contact ring plate. When the spraying rod moves to the position of the lower end of the contact ring plate, under the pressing action of the contact ring plate, the spraying rod will approach the front lamp cover, so that the spraying position is closer to the inside of the front lamp cover, and thus a better spraying effect is achieved. At the same time, under the action of the spring, the spraying rod will always slide and closely adhere to the contact ring plate.

[0023] The spraying rod includes a main rod. The main rod is slidably connected to the slider. A spray head is rotatably connected to one end of the main rod away from the reciprocating ring. The spray head and the main rod are connected by a hose. A return spring is fixedly installed between the spray head and the main rod. A cross bar is fixedly connected to the spray head, and a toggle rod is fixedly installed on the slider corresponding to the cross bar.

[0024] During the process of the spraying rod approaching the front lamp cover, the elastic force of the return spring will keep the spray head and the main rod in a parallel state. When the toggle rod contacts the cross bar, the cross bar will drive the spray head to tilt. The tilting of the spray head can well spray the side of the beam splitter in the front lamp cover, and at the same time will not affect the normal spraying of other positions of the front lamp cover.

[0025] The beneficial effects of the present invention are as follows: 1. In the present invention, the radar detection head monitors the road conditions ahead. When it detects that the road conditions ahead are an uphill road surface, a small motor for driving the beam splitter to rotate is integrated in the front lamp cover. The radar detection head will notify the control terminal in the vehicle, and the control terminal will issue an instruction to drive the driving shaft of the small motor in the front lamp cover to drive the rotation of the beam splitter, so that the beam splitter deflects. When the light shines on the beam splitter, the light will be reflected on the beam splitter, thereby changing the propagation path of the light and illuminating the uphill road surface. When driving on a flat road, the small motor will drive the beam splitter to return to the original position, and the light enters from the side of the beam splitter. The base material of the beam splitter is a transparent material and will not affect the propagation of the light.

[0026] 2. The present invention uses a spraying mechanism to make a circular motion along the spraying ring frame. During the circular motion, the spraying ring frame will evenly spray the headlamp cover. Compared with manual spraying, the spraying effect is more uniform. Compared with the existing equipment, because the spraying mechanism sprays around the headlamp cover, both the inner and outer sides of the headlamp cover can be evenly sprayed, achieving a more comprehensive spraying effect while also enabling the beam splitter to be effectively sprayed.

[0027] 3. In the present invention, when the toggle rod and the cross bar come into contact with each other, the cross bar will drive the spray head to tilt. The tilt of the spray head can spray the side of the beam splitter in the headlamp cover well without affecting the normal spraying of other positions of the headlamp cover.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] To solve the technical problems proposed in the present invention.

[0032] As Figures 1 to 3 shown, the present invention provides an automotive headlamp with a ramp adaptive lighting function, including a mounting bracket 1. A front lamp cover 11 is fixedly installed at the front end of the mounting bracket 1, a condensing cover 12 is fixedly installed at the rear end of the mounting bracket 1, a light source 13 is fixedly installed at the middle position of the condensing cover 12, a radar detection head 14 is fixedly installed on the mounting bracket 1. The front lamp cover 11 is processed into a relatively long cylindrical shape, an opaque material is sprayed on the side surface of the front lamp cover 11, and a beam splitter 15 is rotatably installed at the middle position of the front lamp cover 11. The beam splitter 15 is a lens that can reflect light.

[0033] It should be noted that the mounting bracket 1 is used to mount the automotive headlamp on the vehicle. During the illumination of the automotive headlamp, the light source 13 emits light, and the condenser cover 12 converges the light into a forward illumination state and emits it from the front end of the front lamp cover 11. During the driving of the vehicle, the radar detection head 14 monitors the road conditions ahead. The radar detection head is a prior art and uses the lidar or millimeter-wave radar currently used on vehicles, which can effectively detect the terrain and obstacles. A small motor with a drive shaft fixedly connected to the beam splitter 15 is integrated in the front lamp cover 11. This small motor can use the Sieg transmission micro-motor, and its diameter can reach 8 mm, which is convenient for installation in the relatively narrow space of the condenser cover 12. When it is detected that the road condition ahead is an uphill road surface and the slope is greater than 15 degrees, the radar detection head 14 will notify the control terminal in the vehicle, and the control terminal will issue an instruction to make the drive shaft of the small motor in the front lamp cover 11 drive the beam splitter 15 to rotate, so that the beam splitter 15 rotates 8 degrees. When the light shines on the beam splitter 15 (the lens forming the beam splitter 15 is made of the same material as the existing mirror), the light will be reflected on the beam splitter 15, thereby changing the propagation path of the light. The light source has a width of 5 mm, the width of the beam splitter is 20 mm, and the distance from the light source to the midpoint of the beam splitter is 50 mm. When the light of the light source shines on the beam splitter, a light band between 15 degrees and 22 degrees will be formed, so as to illuminate the ramp. When driving on a flat road, the control terminal will issue an instruction to make the small motor drive the beam splitter 15 to return to the original position. The light enters from the side of the beam splitter 15. The base material of the beam splitter 15 is made of transparent glass and does not affect the propagation of the light. In the prior art, when changing the propagation path of the light, multiple light sources are often used. If this method still needs to ensure the directional propagation of the light, it will lead to a very complex shape structure of the lamp cover, thereby increasing the manufacturing cost. However, the above technical solution will not make the shape of the lamp cover become complex.

[0034] As Figures 4 to 11 shown, the present invention also provides a production device for an automotive headlamp with a ramp adaptive lighting function. This production device is applicable to produce the above-mentioned automotive headlamp with a ramp adaptive lighting function, and can ensure the uniformity of spraying during the process of spraying a strengthening film on the automotive front lamp cover, and can spray the inner and outer end faces of the lamp cover, so that the beam splitter 15 can also be effectively sprayed.

[0035] A production device for an automotive headlamp with a ramp adaptive lighting function includes a fixed frame 2. A driving roller 21 is rotatably mounted on each side of the fixed frame 2, and a driving pulley 22 is fixedly installed on each side of the driving roller 21; The conveying belt 3 is used to connect two driving pulleys 22 on the same side of the driving roller 21, and one conveying belt 3 is provided corresponding to each of the driving pulleys 22 on both sides of the driving roller 21; The loading device 4 is fixedly installed at the middle position between the two conveying belts 3, and the loading devices 4 are evenly distributed on the conveying belts 3; The spraying device 5 includes a spraying ring frame 51 which is fixedly installed on the fixing frame 2. The spraying ring frame 51 surrounds the upper section of the conveying belt 3, and a spraying mechanism 52 for spraying the front lamp shade 11 is arranged on the spraying ring frame 51.

[0036] It should be noted that during the spraying operation of the automobile front lamp shade 11, the automobile front lamp shade 11 is placed on the loading device 4. The driving roller 21 is driven to rotate by the power source. When the driving roller 21 rotates, it will drive the rotation of the driving pulley 22. The driving pulley 22 drives the movement of the conveying belt 3, and the conveying belt 3 drives the movement of the loading device 4. When the loading device 4 drives the front lamp shade 11 to the middle position of the spraying ring frame 51, the spraying mechanism 52 will move in a circular motion along the spraying ring frame 51. At this time, the spraying mechanism 52 will evenly spray the front lamp shade 11. Compared with manual spraying, the spraying effect is more uniform. Compared with the existing equipment for spraying, since the spraying mechanism 52 sprays around the front lamp shade 11, both the inner and outer sides of the front lamp shade 11 can be evenly sprayed, and at the same time, the light splitting plate 15 installed on the front lamp shade 11 can also be effectively sprayed, thereby improving the service life of the light splitting plate 15.

[0037] As Figure 4 shown, the loading device 4 includes a loading rod 41. A placing portion 42 for placing the front lamp shade 11 is fixedly installed in the middle of the loading rod 41. The lower end of the placing portion 42 is in a hollow shape, and the left and right ends of the loading rod 41 are fixedly installed on the conveying belt 3.

[0038] It should be noted that when the front lamp shade 11 is placed in the placing portion 42 of the loading mechanism, it can move along with the movement of the conveying belt 3. And the structure of this loading device 4 is very simple, not only with low cost but also very reliable and durable. The inside of the through hole in the middle of the placing portion 42 is made of rubber material, which can provide friction to fix the placing portion 42.

[0039] As Figure 5 and Figure 6As shown, the loading device 4 includes a loading erection rod 43, a loading part 44 and a connecting mechanism 45. The loading part 44 is arranged in the middle position of the two conveyor belts 3. A through hole for installing the headlight cover 11 is opened in the middle of the loading part 44, and the inside of the through hole of the loading part 44 is made of rubber. A loading erection rod 43 is fixedly connected to the left and right sides of the loading part 44. The front and rear ends of the corresponding loading erection rods 43 on the conveyor belt 3 are fixedly installed with connecting mechanisms 45. The connecting mechanism 45 includes a connecting cover 451 and a connecting spring 452. The connecting cover 451 is fixedly installed on the conveyor belt 3. The end of the connecting cover 451 and the loading erection rod 43 is fixedly connected by a connecting spring 452. A plurality of connecting springs 452 are evenly arranged around the end of the loading erection rod 43.

[0040] It should be noted that the conveyor belt 3 will be more or less deformed after a long period of use. In order to reduce the phenomenon that the headlamp cover 11 is difficult to be placed flat during the placement process due to the deformation of the conveyor belt 3, a longer loading rod 41 is used to set up the loading part 44, which can effectively prevent the loading part 44 from being positioned incorrectly when placing the lamp cover due to deformation of a certain part of the conveyor belt 3. However, at this time, when the loading rod 41 is transported to the driving pulley 22, the distance between the two fixed points on the conveyor belt 3 will change slightly. By connecting the loading setting rod 43 and the connecting cover 451 through the connecting spring 452, the end of the loading setting rod 43 is allowed to be displaced in the connecting cover 451, thereby offsetting the above-mentioned changes in the conveyor belt 3.

[0041] like Figure 4 and Figure 5 、 Figures 7 to 10 As shown, the spraying mechanism 52 includes a spraying ring plate 521, which is rotatably connected to four rollers 522, and the four rollers 522 are clamped on the spraying ring frame 51. The spraying ring plate 521 is fixedly connected to a sliding plate 523, and a sliding groove 5231 is provided on the sliding plate 523. A slider 524 is slidably connected in the sliding groove 5231, and a spraying rod 525 is installed on the slider 524. A reciprocating ring 511 is fixedly installed on the spraying ring frame 51, and a cyclic wavy reciprocating groove 5111 is processed on the inner side of the reciprocating ring 511, and the sliding plate 523 is slidably connected to the reciprocating groove 5111 through a rod.

[0042] It should be noted that during the process of the spraying mechanism 52 making a circular motion around the spraying ring frame 51, by installing a motor on the spraying ring plate 521 to drive the rotation of the roller 522, the roller 522 drives the spraying mechanism 52 to make a circular motion around the front lamp cover 11 during the rotation process. The spraying mechanism of an existing paint spray gun is integrated on the spraying rod 525, and high-pressure gas mixed with coating paint is received through a pipeline. At the same time, since it is difficult to ensure that the paint density at each spraying position is the same during the process of the existing spray gun spraying the paint body, during the process of the spraying mechanism 52 making a circular motion around the spraying ring frame 51, the rod on the sliding plate 523 is slidably connected to the reciprocating groove 5111, so that the spraying slider 524 makes a reciprocating slide along the sliding groove 5231. The spraying slider 524 will drive the spraying rod 525 to make a reciprocating motion at the same time. In this way, during the process of spraying the front lamp cover 11 of the vehicle, the spraying rod 525 can spray various areas of the front lamp cover 11, thereby improving the uniformity during the spraying process.

[0043] The spraying ring plate 521 makes a reciprocating circular motion along the spraying ring frame 51.

[0044] It should be noted that since the spraying mechanism 52 is connected to the pipeline for transporting high-pressure gas mixed with paint, the above-mentioned device can effectively prevent the phenomenon of winding.

[0045] A visual detection head 6 is fixedly installed on the spraying ring plate 521.

[0046] It should be noted that by observing the position of the loading device 4 through the visual detection head 6, when the loading device 4 moves to the middle position of the spraying ring frame 51, a signal can be sent to the relevant control system to stop the rotation of the driving roller 21, and then spray the front lamp cover 11. During the spraying process, a peelable plastic film can be covered on the surface of the visual detection head 6 to protect the visual detection head 6.

[0047] As Figure 4 and Figure 5 、 Figures 7 to 10 As shown, the spraying rod 525 is slidably connected to the slider 524. A spring 526 is sleeved on the spraying rod 525. The spring 526 is fixedly installed at one end of the spraying rod 525 close to the reciprocating ring 511 and on the sliding plate 523. A contact ring plate 512 is fixedly installed on the inner side of the reciprocating ring 511. The contact ring plate 512 is in sliding contact with the spraying rod 525, and the lower end of the contact ring plate 512 protrudes upward.

[0048] It should be noted that since the front lamp cover 11 is concave, in order to achieve the same spraying effect when spraying the inner side of the front lamp cover 11 as when spraying the outer side, the spraying rod 525 slides along the abutting ring plate 512. When the spraying rod 525 moves to the position at the lower end of the abutting ring plate 512, under the pressing action of the abutting ring plate 512, the spraying rod 525 will approach the front lamp cover 11, so that the spraying position is closer to the inside of the front lamp cover 11, thereby achieving a better spraying effect. At the same time, under the action of the spring 526, the spraying rod 525 will always slide and closely adhere to the abutting ring plate 512.

[0049] As Figures 7 to 10 shown, the spraying rod 525 includes a main rod member 5251, the main rod member 5251 is slidably connected to the slider 524, one end of the main rod member 5251 away from the reciprocating ring 511 is rotatably connected to a spray head 5252, the spray head 5252 and the main rod member 5251 are connected by a hose, a return spring 5255 is fixedly installed between the spray head 5252 and the main rod member 5251, a cross bar 5253 is fixedly connected to the spray head 5252, and a toggle rod 5254 is fixedly installed on the slider 524 corresponding to the cross bar 5253.

[0050] It should be noted that during the process of the spraying rod 525 approaching the front lamp cover 11, the elastic force of the return spring 5255 will keep the spray head 5252 and the main rod member 5251 in a parallel state. When the toggle rod 5254 contacts the cross bar 5253, the cross bar 5253 will drive the spray head 5252 to tilt. The spray head 5252 tilts to point to the side of the light splitting plate 15. At this time, the side of the light splitting plate 15 in the front lamp cover 11 can be well sprayed, and at the same time, it will not affect the normal spraying of other positions of the front lamp cover 11.
