Description

Technical Field

[0001] The present invention relates to the field of lamps, and in particular to a vehicle-mounted front lamp and a control method thereof. Background Art

[0002] Some invention patents related to automobile lamps are disclosed in the prior art. A Chinese patent with publication number CN216431590U discloses an automobile lamp with an anti-fog function. The automobile lamp comprises: a lampshade, a headlight cover, a rear light cover, a fog lamp, a heating component and a mounting frame; wherein the heating component is fixed on the lampshade and is located in front of the headlight cover; the mounting frame is connected to the lampshade, the connecting line of the fog lamp is led out through the mounting frame, and the lampshade is installed on the vehicle through the mounting frame, that is, the heating component is suitable for heating the front part of the lampshade to prevent water mist from penetrating into the sealed cavity.

[0003] During the use of the vehicle, water will inevitably enter the headlights. When water enters the front headlights, even a small amount of water will form water mist, which will affect the normal lighting of the bulbs. However, it is not easy for the driver to discover it in time. When the water ingress is serious, water will accumulate, causing the bulbs to short-circuit and causing damage to the headlights. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a vehicle-mounted front lamp and a control method thereof.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0006] In a second aspect, a vehicle-mounted front lamp is provided, comprising a rear cover of the lamp and a reflector mounted on the rear cover of the lamp, wherein the rear cover of the lamp comprises

[0007] The mounting groove is used to mount the lamp holder, and the inner wall of the mounting groove is penetrated by a through groove for the tail end of the reflector to pass through:

[0008] Also includes:

[0009] A lamp body, the lamp body comprising a bulb and a movable seat integrated with the bulb, the bulb having two wiring ears, both of which penetrate the movable seat and extend to the outside of the movable seat, the movable seat penetrates the reflector and is clamped with the reflector through a clamping piece;

[0010] A wiring body, which is arranged at the rear end of the reflector and includes a movable plate and two docking ears fixedly plugged on the movable plate and used for docking with the wiring ears;

[0011] A thread drive unit, used for thread-driven movement of the moving disk, so as to adjust the contact or separation between the docking ear and the wiring ear;

[0012] A humidity sensor, mounted on the lighting side of the rear cover of the headlight, for detecting the humidity on the lighting side of the rear cover of the headlight;

[0013] A water level sensor, used to detect the water level of water seeping into the edge of the reflector;

[0014] The controller prompts the humidity value when the humidity sensor detects a humidity greater than or equal to a specified value and the water level value detected by the water level sensor does not reach the specified water level value. If the water level reaches a value greater than or equal to the specified water level value, the controller controls the threaded drive unit to drive the docking ear away from the wiring ear.

[0015] It should be understood that during the use of the vehicle, water will inevitably enter the headlights. When water enters the front headlights of the vehicle, a small amount of water will form water mist, and the bulb will light up. The water mist will affect the normal lighting of the lamp, but it is not easy for the driver to find it in time. When the water inflow is serious, water will gather, causing the bulb to short-circuit and damage the headlights. This technical solution can solve the above problems. The specific solution process is as follows:

[0016] Receiving a humidity value detected by a humidity sensor and a water level value detected by a water level sensor;

[0017] A judgment is made based on the acquired humidity value and the water level value detected by the water level sensor, when the humidity sensor detects a humidity greater than or equal to a specified value;

[0018] When the humidity sensor detects a humidity greater than or equal to a specified value, and the water level value rises to a value greater than or equal to the specified water level value, the thread drive unit is controlled to start, the thread drive moving disk is moved, the docking ear and the wiring ear are adjusted to be away from each other, and the power connection of the bulb is cut off to form a power-off protection;

[0019] Furthermore, when a small amount of water enters the headlights and causes water mist, the detected humidity value can be prompted and the car owner can be informed in time so that the car owner can discover the problem in time for timely maintenance, which is beneficial to avoid safety hazards caused by water entering the headlights. On rainy days, when a large amount of water enters the headlights and the water accumulates seriously, the power connection of the bulb can be cut off in time to form power-off protection, and the power can be cut off at the grounding point to avoid short-circuit damage to the headlights.

[0020] As a further optimized technical solution of the present invention, it also includes:

[0021] A hot air head, the hot air head is fixedly mounted on the lighting side of the rear cover of the vehicle lamp;

[0022] A hot air blower, which is arranged on the surface of the rear cover of the headlight and is used to inject hot air into the hot air head;

[0023] The controller is also used to start the hot air blower to inject hot air into the lighting side space of the lamp back cover when the humidity sensor detects that the humidity on the lighting side of the lamp back cover reaches a specified value and the water level sensor does not detect the specified water level value, so as to help eliminate water mist.

[0024] It should be understood that the judgment is made based on the acquired humidity value and the water level value detected by the water level sensor. When the temperature sensor detects a humidity greater than or equal to the specified value and the water level value has not risen to the specified water level value, the hot air blower is started to inject hot air into the lighting side space of the rear cover of the lamp through the hot air head to help eliminate water mist. During use, it is helpful to maintain normal lighting of the lamp and maintain good use effect.

[0025] As an optional technical solution of the present invention, the clamping member specifically includes:

[0026] A card-joint seat, the card-joint seat is fixedly mounted on the rear end of the reflector, the card-joint seat comprises a card-joint groove and a plug-in groove connected to the card-joint groove;

[0027] The card-connecting plate is fixedly arranged on the surface of the movable seat, and the edge has a card-connecting ear that docks with the card-connecting slot. During the card-connecting process, the card-connecting ear is passed through the plug-in slot and then the card-connecting plate is rotated to make the card-connecting ear move into the card-connecting slot to form a card-connecting connection.

[0028] It should be understood that the snap-fitting parts facilitate detachable installation during the installation process, and the rotating snap-fitting installation is convenient and quick.

[0029] As a further optimized technical solution of the present invention, the wiring body further includes:

[0030] A connecting cover, the connecting cover being threadedly connected to the surface of the rear cover of the vehicle lamp;

[0031] The mounting plate is rotatably connected to the end of the connecting cover, and a limiting rod is movably inserted at the edge, and the limiting rod is fixedly connected to the surface of the rear cover of the vehicle lamp, and the two docking ears both movably penetrate the mounting plate.

[0032] As an optional technical solution of the present invention, the thread drive unit includes

[0033] A threaded rod, a movable frame being threadedly connected on the surface of the threaded rod, and the movable frame being fixedly mounted on the edge of the movable plate;

[0034] The motor is fixedly mounted on the surface of the rear cover of the vehicle lamp, and the output end of the motor is fixedly connected to the end of the threaded rod, so as to drive the threaded rod to rotate and drive the movable frame to move by the thread.

[0035] As a further optimized technical solution of the present invention, a positioning component is also included, and the positioning component includes:

[0036] A boss, the boss is fixedly arranged at the end of the movable seat, and the surface of the boss is a spiral table surface;

[0037] The protruding column is connected to an elastic support component. During the process of threaded connection between the connecting cover and the rear cover of the headlight, the protruding column will contact the boss and the protruding boss will rotate, so that the clamping plate rotates on the clamping seat until the clamping ear is completely docked with the clamping groove.

[0038] It should be understood that during the process of threaded connection between the connecting seat and the rear cover of the car light, before the wiring ear contacts the docking ear, the convex column has already contacted the boss, and the convex column rotates, and the boss synchronously drives the movable seat to rotate, so that the snap-in ear located in the plug-in slot moves toward the depth of the snap-in slot until it is fully engaged. Under the support of the elastic support assembly, the elastic support is maintained, and the process of gradual tightening is achieved, and in the process of threaded connection between the connecting seat and the rear cover of the car light, it is gradually tightened.

[0039] As an optional technical solution of the present invention, the connection assembly includes:

[0040] Two connecting seats, the two connecting seats are respectively movably sleeved on the ends of the convex pillars, a first supporting spring is arranged inside the connecting seat, two ends of the first supporting spring are respectively fixedly connected to the connecting seat and the ends of the convex pillars, and the ends of the connecting seat are in contact with the surface of the moving disk;

[0041] A connecting ring is fixedly sleeved on the surface of the convex column, and a second supporting spring is fixedly connected between the connecting ring and the mounting plate.

[0042] It should be understood that during the process of threaded connection between the connecting cover and the rear cover of the vehicle lamp, the mounting plate will support the convex column to convex the spiral table surface of the boss under the support of the second supporting spring, so as to realize the rotational convex movement of the movable seat and maintain the stability of the clamping;

[0043] Furthermore, after the connecting cover is threadedly connected to the rear cover of the headlight, when the threaded driving unit is started to threadably drive the moving disk, the moving disk will first contact the connecting seat while driving the docking ear to contact the wiring ear. In the process of the connecting seat compressing the first supporting spring, the contact force between the protruding column and the boss is further stabilized, and the stability of the clamping connection between the clamping disk and the clamping seat is further stabilized, providing stable conditions for the docking of the docking ear with the wiring ear in the next step.

[0044] As an optional technical solution of the present invention, the water level sensor includes:

[0045] A sealing ring, the sealing ring being movably arranged at the edge of the reflector and the opening edge of the mounting groove;

[0046] A moving contact, wherein the moving contact is fixedly arranged at the bottom end of the back side of the sealing ring;

[0047] An arc-shaped conductive rod, one end of which is fixedly connected to the surface of the reflector and penetrates and contacts the moving contact, and the bottom ends of the moving contact and the arc-shaped conductive rod are connected to the positive and negative poles of the power supply of the external device;

[0048] A floating block, the floating block is fixedly connected to the surface of the sealing ring close to the lighting side and close to the bottom end of the sealing ring;

[0049] The current detection unit is used to detect the current passing through the arc-shaped conductive rod and the moving contact, and judge the height of the moving contact on the arc-shaped conductive rod according to the current value. The smaller the current, the higher the float rises, the moving contact moves toward the top of the arc-shaped conductive rod, and the larger the water level value.

[0050] It should be understood that during the process of water accumulation in the lamp, when the water surface contacts the float, the float will drive the sealing ring to rotate under the action of the buoyancy of the water, and the float will rise in height, thereby driving the moving contact to move on the arc-shaped conductive rod, and the moving contact moves toward the top of the arc-shaped conductive rod. When the moving contact and the bottom end of the arc-shaped conductive rod are energized, the energized length of the arc-shaped conductive rod increases, which means that the resistance of the energization increases. Therefore, the current value of the current passing through the arc-shaped conductive rod detected by the current detection unit decreases, indicating that the float is rising, the moving contact moves toward the top of the arc-shaped conductive rod, and the water level value increases, thereby realizing the detection of the water level inside the reflector while maintaining the seal.

[0051] It should be further explained that the height maintained by the float when it does not touch the water is the initial height, which is the initial water level. Even if there is water accumulation, it does not touch the bulb position. Therefore, the specified water level value is not reached. When the accumulated water is close to the height of the bulb, it is set to the water level value at the point where the bulb wiring is disconnected.

[0052] As a further optimized technical solution of the present invention, a plurality of support seats are fixedly connected to the surface of the reflector, and the support seats are fastened to the rear cover of the vehicle lamp by bolt threads.

[0053] In a first aspect, a method for controlling a vehicle front lamp is provided, comprising the following steps:

[0054] Receiving a humidity value detected by a humidity sensor and a water level value detected by a water level sensor;

[0055] According to the humidity value detected by the humidity sensor and the water level value detected by the water level sensor, a judgment is made. When the humidity sensor detects a humidity greater than or equal to a specified value and the water level value does not rise to the specified water level value, the hot air blower is started to inject hot air into the lighting side space of the rear cover of the lamp through the hot air head, so as to help eliminate water mist;

[0056] When the humidity sensor detects a humidity greater than or equal to a specified value, and the water level value rises to a value greater than or equal to the specified water level value, the control thread drive unit starts, drives the movable disk to move, adjusts the docking ear and the wiring ear to move away from each other, and cuts off the power to the bulb connection point to form power-off protection.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] The present invention can prompt the detected humidity value when a small amount of water enters the headlights and causes water mist, and promptly inform the car owner so that the car owner can find the problem in time for timely maintenance, which is beneficial to avoiding safety hazards caused by water entering the headlights. On rainy days, when a large amount of water enters the headlights and the water accumulates seriously, the power connection of the bulb is promptly cut off to form power-off protection, and the power is cut off at the grounding point to avoid short-circuit damage to the headlights.

[0059] The judgment is made based on the acquired humidity value and the water level value detected by the water level sensor. When the temperature sensor detects a humidity greater than or equal to the specified value and the water level value has not risen to the specified water level value, the hot air blower is started to inject hot air into the lighting side space of the rear cover of the lamp through the hot air head to help eliminate water mist. During use, it is helpful to maintain normal lighting of the lamp and maintain a good use effect.

[0060] By setting a connecting component, in cooperation with the moving disk, the contact force between the convex column and the boss is further stabilized, and the stability of the clamping connection between the clamping disk and the clamping seat is further stabilized, providing stable conditions for the docking of the docking ear with the wiring ear in the next step.

[0061] By setting up the specific components of the water level sensor, the water level inside the reflector can be detected while maintaining the seal, and the water level can be detected in time to provide intelligence information for the power-off control of the bulb.

DETAILED DESCRIPTION

[0081] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0082] like Figures 2 to 18 The vehicle-mounted front lamp shown in the figure comprises a rear cover 1 for the vehicle lamp and a reflector 2 mounted on the rear cover 1 for the vehicle lamp. The rear cover 1 for the vehicle lamp comprises:

[0083] The mounting groove 101 is used to mount the lamp holder, and the inner wall of the mounting groove 101 is penetrated by a through groove for the tail end of the reflector 2 to pass through:

[0084] Also includes:

[0085] The lamp body includes a bulb 3 and a movable seat 4 integrated with the bulb 3. The bulb 3 has two wiring ears 5. The two wiring ears 5 both penetrate the movable seat 4 and extend to the outside of the movable seat 4. The movable seat 4 penetrates the reflector 2 and is clamped with the reflector 2 through a clamping piece.

[0086] The wiring body is arranged at the rear end of the reflector 2 and comprises a movable plate 6 and two docking ears 7 fixedly plugged on the movable plate 6 and used for docking with the wiring ears 5;

[0087] A thread drive unit, used for thread-driving the moving disk 6 to move, so as to adjust the docking lug 7 to contact or be away from the wiring lug 5;

[0088] A humidity sensor 8 is installed on the lighting side of the rear cover 1 of the vehicle lamp, and is used to detect the humidity on the lighting side of the rear cover 1 of the vehicle lamp;

[0089] A water level sensor 9, used to detect the water level of the infiltrated water at the edge of the reflector 2;

[0090] The controller 10 prompts the humidity value when the humidity sensor 8 detects a humidity greater than or equal to a specified value and the water level value detected by the water level sensor 9 does not reach the specified water level value. If the water level reaches a value greater than or equal to the specified water level value, the controller 10 controls the threaded drive unit to drive the docking ear 7 away from the wiring ear 5.

[0091] The specific prompting method can be played through the vehicle-mounted display screen or player. This method is existing technology and will not be described in detail.

[0092] The controller 10 is a vehicle-mounted control unit, which is specifically a server disposed in the vehicle body. It is a prior art and will not be described in detail.

[0093] It should be understood that during the use of the vehicle, water will inevitably enter the headlight. When water enters the front headlight of the vehicle, a small amount of water will form water mist, and the light bulb 3 will light up. The water mist will affect the normal lighting of the lamp, but it is difficult for the driver to find it in time. When the water inflow is serious, water will gather, causing the light bulb 3 to short-circuit and damage the headlight. This embodiment can solve the above problem. The specific solution process is as follows:

[0094] Receiving the humidity value detected by the humidity sensor 8 and the water level value detected by the water level sensor 9;

[0095] A judgment is made based on the acquired humidity value and the water level value detected by the water level sensor 9, when the humidity sensor 8 detects a humidity greater than or equal to a specified value;

[0096] When the humidity sensor 8 detects a humidity greater than or equal to a specified value, and the water level value rises to a value greater than or equal to the specified water level value, the thread drive unit is controlled to start, the thread drive moving disk 6 moves, the docking ear 7 is adjusted to be away from the wiring ear 5, and the power connection of the bulb 3 is cut off to form a power-off protection;

[0097] Furthermore, when a small amount of water enters the headlights and causes water mist, the detected humidity value can be prompted and the car owner can be informed in time, so that the car owner can discover the problem in time for timely maintenance, which is conducive to avoiding safety hazards caused by water entering the headlights. On rainy days, when a large amount of water enters the headlights and the water accumulation is serious, the power connection of the bulb 3 is promptly cut off to form power-off protection, and the power is cut off at the grounding point to avoid short-circuit damage to the headlights.

[0098] As a further optimized embodiment of the present invention, it also includes:

[0099] A hot air head 11, which is fixedly mounted on the lighting side of the rear cover 1 of the vehicle lamp;

[0100] A hot air blower 12, which is arranged on the surface of the rear cover 1 of the vehicle lamp and is used to inject hot air into the hot air head 11;

[0101] The controller 10 is also used to start the hot air blower 12 to inject hot air into the lighting side space of the lamp rear cover when the humidity sensor 8 detects that the humidity on the lighting side of the lamp rear cover reaches a specified value and the water level sensor 9 does not detect the specified water level value, so as to help eliminate water mist.

[0102] It should be noted that a ventilation hole is provided at the top of the rear cover 1 of the vehicle lamp so that the injected hot air can carry away moisture.

[0103] It should be understood that the judgment is made based on the acquired humidity value and the water level value detected by the water level sensor 9. When the temperature sensor detects a humidity greater than or equal to the specified value and the water level value has not risen to the specified water level value, the hot air blower 12 is started, and hot air is injected into the lighting side space of the rear cover of the lamp through the hot air head 11 to help eliminate water mist. During use, it is helpful to maintain normal lighting of the lamp and maintain a good use effect.

[0104] As an optional embodiment of the present invention, the clamping member specifically includes:

[0105] A clamping seat 13, which is fixedly mounted on the rear end of the reflector 2, and includes a clamping slot 14 and an inserting slot 15 connected to the clamping slot 14;

[0106] The snap-in plate 16 is fixedly arranged on the surface of the movable seat 4, and has a snap-in ear 17 on its edge that docks with the snap-in slot 14. During the snap-in process, the snap-in ear 17 is passed through the insertion slot 15 and then the snap-in plate 16 is rotated to move the snap-in ear 17 into the snap-in slot 14 to form a snap connection.

[0107] It should be understood that the snap-fitting parts facilitate detachable installation during the installation process, and the rotating snap-fitting installation is convenient and quick.

[0108] As a further optimized embodiment of the present invention, the wiring body further includes:

[0109] A connecting cover 18, the connecting cover 18 is threadedly connected to the surface of the rear cover 1 of the vehicle lamp;

[0110] The mounting plate 19 is rotatably connected to the end of the connecting cover 18 , and a limit rod 20 is movably inserted at the edge. The limit rod 20 is fixedly connected to the surface of the rear cover 1 of the vehicle lamp, and the two docking ears 7 both movably penetrate the mounting plate 19 .

[0111] It should be understood that the installation of the mounting plate 19 is achieved through the threaded connection between the connecting cover 18 and the rear cover 1 of the headlight. Under the limitation of the limiting rod 20, the moving direction of the mounting plate 19 remains unchanged. With the indirect support of the mounting plate 19, it is beneficial to maintain the docking ear 7 in the docking direction.

[0112] As an optional embodiment of the present invention, the thread drive unit includes

[0113] A threaded rod 21, a movable frame 22 is threadedly connected to the surface of the threaded rod 21, and the movable frame 22 is fixedly installed at the edge of the movable plate 6;

[0114] The motor 23 is fixedly mounted on the surface of the rear cover 1 of the vehicle lamp, and the output end of the motor 23 is fixedly connected to the end of the threaded rod 21, so as to drive the threaded rod 21 to rotate, thereby driving the moving frame 22 to move by the thread.

[0115] It should be understood that during the docking process, the motor 23 is started, the motor 23 drives the threaded rod 21 to rotate, the threaded shelf will threadably drive the movable frame 22 to move, the movable frame 22 synchronously drives the movable plate 6 to move, and the movable plate 6 synchronously drives the two docking ears 7 to contact with the wiring ears 5 to form an electrical connection. When power needs to be cut off, the motor 23 is started to rotate, driving the movable frame 22 to move in the opposite direction, driving the docking ears 7 to break contact with the wiring ears 5.

[0116] As a further optimized embodiment of the present invention, a positioning component is also included, and the positioning component includes:

[0117] The boss 24 is fixedly arranged at the end of the movable seat 4, and the surface of the boss 24 is a spiral table surface;

[0118] The protruding column 25 is connected to an elastic support component. During the process of threaded connection between the connecting cover 18 and the rear cover 1 of the vehicle lamp, the protruding column 25 will contact the boss 24 and the protruding boss 24 will rotate, so that the clamping plate 16 rotates on the clamping seat 13 until the clamping ear 17 is completely docked with the clamping groove 14.

[0119] It should be understood that during the process of threaded connection between the connecting seat 26 and the rear cover 1 of the headlight, before the wiring ear 5 contacts the docking ear 7, the convex column 25 has already contacted the boss 24, and the convex column rotates, and the boss 24 synchronously drives the movable seat 4 to rotate, so that the snap-in ear 17 located in the plug-in slot 15 moves toward the depth of the snap-in slot 14 until it is fully snapped. Under the support of the elastic support assembly, the elastic support is maintained, and the process of gradual tightening is achieved. In the process of threaded connection between the connecting seat 26 and the rear cover 1 of the headlight, it is gradually tightened.

[0120] As an optional embodiment of the present invention, the connection component includes:

[0121] Two connecting seats 26, the two connecting seats 26 are respectively movably sleeved on the ends of the convex pillar 25, and a first supporting spring 27 is arranged inside the connecting seat 26, and the two ends of the first supporting spring 27 are respectively fixedly connected to the connecting seat 26 and the ends of the convex pillar 25, and the ends of the connecting seat 26 are in contact with the surface of the movable plate 6;

[0122] The connecting ring 28 is fixedly sleeved on the surface of the convex column 25 , and a second supporting spring 29 is fixedly connected between the connecting ring 28 and the mounting plate 19 .

[0123] It should be understood that during the process of threaded connection between the connecting cover 18 and the rear cover 1 of the vehicle lamp, the mounting plate 19 will support the protruding column 25 to protrude the spiral table surface of the boss 24 under the support of the second supporting spring 29, so as to realize the rotational protrusion of the movable seat 4 and maintain the stability of the clamping;

[0124] Furthermore, after the connecting cover 18 is threadedly connected with the rear cover 1 of the vehicle lamp, when the threaded driving unit is started to threadably drive the movable disk 6 to move, the movable disk 6 will first contact the connecting seat 26 while driving the docking ear 7 to contact the wiring ear 5. In the process of the connecting seat 26 compressing the first supporting spring 27, the contact force between the convex column 25 and the boss 24 is further stabilized, and the stability of the clamping between the clamping disk 16 and the clamping seat 13 is further stabilized, providing stable conditions for the docking of the docking ear 7 with the wiring ear 5 in the next step.

[0125] As an optional embodiment of the present invention, the water level sensor 9 includes:

[0126] A sealing ring 30, which is movably arranged at the edge of the reflector 2 and the opening edge of the mounting groove 101;

[0127] A moving contact 31, which is fixedly arranged at the bottom end of the back side of the sealing ring 30;

[0128] An arc-shaped conductive rod 32, one end of which is fixedly connected to the surface of the reflector 2 and penetrates and contacts the moving contact 31, and the bottom ends of the moving contact 31 and the arc-shaped conductive rod 32 are connected to the positive and negative electrodes of the external power supply 37;

[0129] A floating block 33, the floating block 33 is fixedly connected to the surface of the sealing ring 30 close to the lighting side and close to the bottom end of the sealing ring 30;

[0130] The current detection unit 34 is used to detect the current passing through the arc-shaped conductive rod 32 and the moving contact 31, and judge the height of the moving contact 31 on the arc-shaped conductive rod 32 according to the current value. The smaller the current, the higher the float 33 rises, the moving contact 31 moves toward the top of the arc-shaped conductive rod 32, and the larger the water level value.

[0131] It should be understood that during the process of water accumulation in the lamp, when the water surface contacts the float 33, the float 33 will drive the sealing ring 30 to rotate under the action of the buoyancy of the water, and the float 33 will rise in height, thereby driving the moving contact 31 to move on the arc-shaped conductive rod 32, and the moving contact 31 moves toward the top of the arc-shaped conductive rod 32. When the moving contact 31 and the bottom end of the arc-shaped conductive rod 32 are energized, the energized length of the arc-shaped conductive rod 32 increases, which means that the resistance of the energization increases. Therefore, the current value of the current passing through the arc-shaped conductive rod 32 detected by the current detection unit 34 decreases, indicating that the float 33 is rising, the moving contact 31 moves toward the top of the arc-shaped conductive rod 32, and the water level value increases, thereby realizing the detection of the water level inside the reflector 2 while maintaining the seal.

[0132] It should be further explained that the height maintained by the float 33 when not in contact with water is the initial height, which is the initial water level. Even if there is accumulated water, it does not touch the position of the bulb 3. Therefore, the specified water level value is not reached. When the accumulated water is close to the height of the bulb 3, it is set to the water level value at the point where the bulb 3 wiring is disconnected.

[0133] As a further optimized embodiment of the present invention, a plurality of support seats 35 are fixedly connected to the surface of the reflector 2 , and the support seats 35 are threadedly fastened to the rear cover 1 of the vehicle lamp via bolts 36 .

[0134] like Figure 1 A control method for a vehicle front lamp shown in the figure comprises the following steps:

[0135] Receiving the humidity value detected by the humidity sensor 8 and the water level value detected by the water level sensor 9;

[0136] According to the humidity value detected by the humidity sensor 8 and the water level value detected by the water level sensor 9, a judgment is made. When the humidity sensor 8 detects a humidity greater than or equal to a specified value and the water level value does not rise to the specified water level value, the hot air blower 12 is started to inject hot air into the lighting side space of the rear cover of the lamp through the hot air head 11, so as to help eliminate water mist;

[0137] When the humidity sensor 8 detects a humidity greater than or equal to a specified value and the water level value rises to a value greater than or equal to the specified water level value, the control thread drive unit starts, drives the movable disk 6 to move, adjusts the docking ear 7 and the wiring ear 5 to be away from each other, and cuts off the power supply to the power connection of the bulb 3 to form a power-off protection.

[0138] It should be understood that during the control process, the humidity sensor 8 and the water level sensor 9 will respectively detect the humidity and water level in the lighting area of ​​the lamp, and transmit the detected information to the controller 10. The controller 10 compares the humidity value and water level value set in advance. The controller 10 generates control information based on the comparison result of the received information, and controls the threaded drive unit and the hot air blower 12 respectively.

[0139] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
