Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a headlight lens with high and low beam functions. Background Technology

[0002] The high and low beam functions of car headlights are core technologies for ensuring nighttime driving safety. The high beam generates a parallel, strong beam through a reflector focal design, with an illumination distance of over 100 meters, meeting the long-distance visibility needs of unlit roads. The low beam adopts an off-focus design, with the beam tilted downwards at about 15°, covering a short distance of 30-50 meters of road surface, avoiding direct illumination of the oncoming driver's line of sight and reducing the risk of glare. When meeting oncoming traffic, you must switch to low beam at a distance of 150m. However, due to the height difference of the headlight lens caused by different vehicle models, even if you switch between high and low beam in time, the low beam may still cause glare to the oncoming vehicle. At the same time, most vehicles use bi-xenon lenses or split designs for their headlights, which cannot change the beam height and angle in time and rely on manual adjustment. If the lamp is damaged, the high and low beam switching function will be lost and you will need to stop for inspection.

[0003] Patent CN115507339B discloses an ultra-narrow lens high and low beam module. The above patent achieves high and low beam functions while greatly shortening the distance in the X direction, saving space inside the headlight.

[0004] The aforementioned patent places the high beam module above or below the low beam module. The low beam light source forms a low beam pattern through a primary low beam optical structure, a secondary low beam optical structure, and a tertiary low beam optical structure. The high beam light source forms a high beam pattern through a primary high beam optical structure and a high beam headlight optical structure. By using independently set high beam and low beam light sources for switching between high and low beams, the patent avoids the problem of traditional high and low beam modules occupying too much space inside the headlight, thus saving internal headlight space and providing room for optimization in the stability of high and low beams.

[0005] Therefore, this application proposes a headlight lens with high and low beam functions that can adjust the height and angle of high and low beams. Summary of the Invention

[0023] Example 1: Please refer to Figure 1 and Figure 2A headlight lens with high and low beam functions includes a base 1. A high beam lamp group 2 is installed on the front side of the outer wall of the base 1. A low beam lamp group 3 is installed on the left side of the outer wall of the high beam lamp group 2. A high beam lamp group 4 is installed on the left side of the outer wall of the low beam lamp group 3. A slider 5 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the base 1. A slide rail 6 is installed at the connection between the slider 5 and the base 1. The slider 5 is connected to an adapter at the output end of an adjustment motor 7 installed on the rear side of the outer wall of the base 1 via a connecting shaft. A vision sensor 8 is installed on the upper side of the outer wall of the base 1. A locking device 9 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the slider 5. The adjustment motor 7, the vision sensor 8, and the locking device 9 are all connected to an on-board terminal via signal transmission. Fixers 10 are installed on both the left and right sides of the outer walls of the high beam group 1 2, low beam group 3 and high beam group 2 4. Fixers 10 are fixedly connected to the fixing port 11 provided on the front side of the outer wall of the base 1 by mechanical locking. A rotator 12 is installed at the connection between the locker 9 and the slider 1 5. Angle sensors 13 are installed at the connection between the rotator 12 and the locker 9 and the slider 1 5. Fixers 10 and angle sensors 13 are respectively connected to the vehicle terminal through signal transmission. Rotator 12 is connected to the adapter at the output end of the adjustment motor 7 through the connecting shaft. Furthermore, when driving on the road, users can use the high beam group 1 (2), low beam group 3, or high beam group 2 (4) to provide additional illumination when ambient light is insufficient, ensuring accurate collection of road information. When encountering oncoming traffic, the high beams must be switched to low beams to avoid dazzling oncoming drivers. However, in actual oncoming scenarios, due to differences in headlight mounting positions (SUVs and trucks generally have higher headlight mounting positions than sedans), even if the high beams are switched to low beams promptly, the horizontal illumination baseline of the low beams may be close to or higher than the eye level of a sedan driver, such as an SUV. The low beam headlights are approximately 70-90cm high, while the driver's eye level is approximately 60-70cm. However, when meeting oncoming traffic on bumpy roads or slopes with elevation differences, the high-mounted headlights may shine directly into the eyes of the oncoming driver, causing temporary glare. To avoid this, a vision sensor 8 collects information about vehicles in the oncoming lane. When oncoming traffic is detected, the driver issues a command to adjust the high and low beam height via the vehicle terminal. The vehicle terminal then controls the fixing device 10 to disconnect from the fixing port 11. Subsequently, the vehicle terminal controls the adapter at the output of the adjusting motor 7 to connect to slider 5. Slider 5... Driven by the adjusting motor 7, the positions of the high beam group 12, low beam group 3, or high beam group 24 on the slide rail 16 are adjusted, thereby adjusting the height of the high and low beams of the car's headlights. This prevents oncoming drivers from being dazzled by the height difference when meeting oncoming traffic. Compared to relying on manual adjustment by the driver, which carries the risk of distraction and lag, this method can promptly prevent accidents. Furthermore, to avoid the beam angle not converging after adjusting the height of the high or low beams, causing scattered light to penetrate the windshield of oncoming vehicles and create superimposed scattering and blind spots, the on-board terminal synchronously controls the adapter at the output of the adjusting motor 7, which connects to the rotary device 12. While adjusting the height, the regulating motor 7 synchronously delivers power to the rotary device 12, so that the angle of the high beam or low beam is adjusted when adjusting the height of the high beam or low beam. According to the height change of the high beam or low beam, the angle sensor 13 collects the angle change of the rotary device 12 for the high beam or low beam. For example, if the height of the low beam group 3 of the vehicle decreases by 0.1m to 0.15m, the angle of the low beam group 3 needs to be increased by 0.5° to 1° through the rotary device 12. If the height of the high beam group 2 or high beam group 4 of the vehicle decreases by 0.1m, the angle of the high beam group 2 or high beam group 4 needs to be increased by 0.2° to 0.4° through the rotary device 12.

[0024] Example 2: Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5A headlight lens with high and low beam functions, wherein the high beam group 1 2 and the high beam group 2 4 are both composed of a high beam light source 14, a reflector bowl 15, a light shield 16, a telescopic shaft 17 and a lens 18. The high beam light source 14 is installed on the front side of the outer wall of the locking device 9. The reflector bowl 15 is installed at the connection between the high beam light source 14 and the base 1. The light shield 16 is installed on the front side of the outer wall of the high beam light source 14. The lens 18 is installed on the front side of the outer wall of the light shield 16. The light shield 16 is connected to the adapter of the conversion motor 19 installed on the right side of the outer wall of the adjustment motor 7 through the telescopic shaft 17. The conversion motor 19 is connected to the vehicle terminal through signal transmission. The low beam headlight assembly 3 consists of a low beam light source 20, a reflector bowl 21, a lens 22, a slide rail 23, and a slider 24. The low beam light source 20 is installed on the front side of the outer wall of the base 1. The reflector bowl 21 is installed at the connection between the low beam light source 20 and the base 1. The lens 22 is installed on the front side of the outer wall of the low beam light source 20. The slider 24 is installed on the lower side of the outer wall of the lens 22. The slide rail 23 is installed on the lower side of the outer wall of the slider 24. The lens 22 is connected to the base 1 through the slider 24 and the slide rail 23. The slider 24 is connected to the adapter at the output end of the conversion motor 19 through a connecting shaft. The protective cover 25 is connected to the base 1 via a heat sink 36. A heat sink 37 is provided on the outer wall of the heat sink 36. A baffle 38 is installed at the connection between the heat sink 37 and the heat sink 36. The baffle 38 is connected to the adapter at the output end of the regulating motor 7 via a connecting shaft. A temperature sensor 39 is provided on the outer wall of the baffle 38 near the low beam headlight assembly 3. The temperature sensor 39 is connected to the regulating motor 7 and the vehicle terminal respectively via signal transmission. A light sensor 40 is installed on the upper side of the outer wall of the temperature sensor 39. The light sensor 40 is connected to the conversion motor 19 and the vehicle terminal respectively through signal transmission. Furthermore, if drivers do not regularly inspect and maintain their vehicles, high / low beam switching malfunctions may occur during driving, resulting in the inability to switch between high and low beams. If the vehicle's headlights are integrated, the vehicle will completely lose its lighting capability in the event of a sudden malfunction. If separate headlights are used, the inability to switch between high and low beams in the event of a malfunction poses a safety hazard. In addition, insufficient high / low beam intensity due to factors such as lamp aging or dirt on the lamp surface can make it difficult for drivers to identify road signs, obstacles, and pedestrians, increasing the possibility of driving accidents. To ensure normal vehicle operation, during driving, the on-board terminal controls the adjustment motor 7 connected to the baffle 38, which closes the heat dissipation vent 37 on the heat sink 36. This prevents the light sensor 40 from being affected by ambient light when collecting internal high or low beam intensity data. When the light sensor 40 detects insufficient internal high or low beam intensity, a high / low beam malfunction occurs. The driver issues a command through the on-board terminal, which controls the adapter at the output of the conversion motor 19 to connect... The telescopic shaft 17, driven by the conversion motor 19, adjusts the position of the light-shielding plate 16, causing it to block either the high beam group 12 or the high beam group 2 4. The light emitted from the high beam source 14, after being focused by the reflector bowl 15, is blocked by the light-shielding plate 16 and then processed by the lens 18 to form a low beam with a clear cutoff line. This is used to address situations where the low beam group 3 malfunctions and cannot provide low beam illumination, or where the low beam group 3 malfunctions and cannot provide sufficient low beam illumination. The vehicle terminal controls the conversion motor. The adapter at the output end of motor 19 connects to slider 24. Driven by the conversion motor 19, slider 24 slides on slide rail 23, causing lens 22 to move. This adjusts the distance between lens 22 and low beam light source 20, so that the light emitted by low beam light source 20 is focused by reflector bowl 21 and processed by lens 22 to become high beam. This is used to deal with situations where high beam group 12 or high beam group 24 malfunctions and cannot switch to high beam or the high beam intensity is insufficient, thereby avoiding accidents caused by malfunctions during driving.

[0025] Example 3: Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8A headlight lens with high and low beam functions includes a base 1. A high beam lamp group 2 is installed on the front side of the outer wall of the base 1. A low beam lamp group 3 is installed on the left side of the outer wall of the high beam lamp group 2. A high beam lamp group 4 is installed on the left side of the outer wall of the low beam lamp group 3. A slider 5 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the base 1. A slide rail 6 is installed at the connection between the slider 5 and the base 1. The slider 5 is connected to an adapter at the output end of an adjustment motor 7 installed on the rear side of the outer wall of the base 1 via a connecting shaft. A vision sensor 8 is installed on the upper side of the outer wall of the base 1. A locking device 9 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the slider 5. The adjustment motor 7, the vision sensor 8, and the locking device 9 are all connected to an on-board terminal via signal transmission. Fixers 10 are installed on both the left and right sides of the outer walls of the high beam group 1 2, low beam group 3 and high beam group 2 4. Fixers 10 are fixedly connected to the fixing port 11 provided on the front side of the outer wall of the base 1 by mechanical locking. A rotator 12 is installed at the connection between the locker 9 and the slider 1 5. Angle sensors 13 are installed at the connection between the rotator 12 and the locker 9 and the slider 1 5. Fixers 10 and angle sensors 13 are respectively connected to the vehicle terminal through signal transmission. Rotator 12 is connected to the adapter at the output end of the adjustment motor 7 through the connecting shaft. A protective cover 25 is installed on the front side of the outer wall of the base 1. A storage box 26 is installed on the upper side of the outer wall of the base 1, and a storage box 27 is installed on the lower side of the outer wall of the base 1. A replacement valve 28 is provided on the outer wall of both storage box 26 and storage box 27 near the base 1. The replacement valve 28 is connected to the base 1 via a slide rail 6. A connector 29 is installed in the middle of the inner wall of the base 1. The connector 29 is connected to the high beam headlight group 2, the low beam headlight group 3 and the high beam headlight group 4 respectively via a locking device 9. A current sensor 30 is installed at the connection between the connector 29 and the locking device 9. The replacement valve 28 and the current sensor 30 are connected to the vehicle terminal via signal transmission. The inner wall of the storage box 26 is provided with a partition plate 41, a push rod 42 is installed on the upper side of the inner wall of the storage box 26, a guide rail 43 is installed on the lower side of the outer wall of the push rod 42, and the output end of the guide rail 43 is connected to the replacement valve 28. A buffer pad 44 is installed at the bottom of the inner wall of the storage box 27. A guide rail 45 is installed on the upper side of the outer wall of the buffer pad 44. The input end of the guide rail 45 is connected to the replacement valve 28. An infrared sensor 46 is installed on the upper side of the inner wall of the storage box 27. The infrared sensor 46 is connected to the replacement valve 28 and the vehicle terminal respectively through signal transmission. Furthermore, if a faulty high beam or low beam is not replaced promptly, it will not only affect the driver's driving but also cause uneven lighting due to unilateral light failure. At night or in low-light conditions, drivers will find it difficult to accurately judge road boundaries and obstacle positions. When driving on curves, the inner blind spot will expand, increasing the risk of collision. A faulty low beam forces the driver to rely on the high beam, and failure to switch to high beams in time when meeting oncoming traffic can cause momentary glare, easily leading to a head-on collision. Therefore, it is necessary to replace faulty high beams or low beams promptly to avoid traffic accidents. (The last sentence appears to be incomplete and possibly refers to a separate issue: "When the current sensor detects high beam...") When an abnormal current occurs at the connection point between the locking device 9 and connector 29 of the lamp group 1 (2), low beam lamp group 3, or high beam lamp group 2 (4), the replacement valve 28 on the lower side of the vehicle terminal control base 1 opens, connecting the adjusting motor 7 and slider 15. This allows the faulty high beam lamp group 1 (2), low beam lamp group 3, or high beam lamp group 2 (4) to move along slide rail 16 to below the base 1. Subsequently, the locking device 9 disconnects the connector 29 from the high beam lamp group 1 (2), low beam lamp group 3, or high beam lamp group 2 (4), allowing the high beam lamp group 1 (2), low beam lamp group 3, or high beam lamp group 2 (4) to enter the storage box 27 from the replacement valve 28 and fall into the storage box 27 along guide rail 245. At the bottom, a flexible buffer pad 44 cushions the impact of falling, preventing further damage to the high beam group 1 (2), low beam group 3, or high beam group 2 (4). An infrared sensor 46 detects whether the storage box 2 (27) is full of damaged lamps. The replacement valve 28 above the vehicle terminal control base 1 opens, and the slider 1 (5) moves the locking device 9 above the base 1. Then, the adjusting motor 7 and push rod 42 are connected, pushing the high beam group 1 (2), low beam group 3, or high beam group 2 (4) stored in the storage box 1 (26) along the guide rail 1 (43). Under gravity, the high beam group 1 (2), low beam group 3, or high beam group 2 (4) for replacement is moved. 2. The low beam headlight assembly 3 or the high beam headlight assembly 4 enters the slide rail 6 through the replacement valve 28. The vehicle terminal control lock 9 connects to the new high beam headlight assembly 2, low beam headlight assembly 3 or high beam headlight assembly 4 to complete the replacement. During this process, in order to prevent the new high beam headlight assembly 2, low beam headlight assembly 3 or high beam headlight assembly 4 from sliding down the guide rail 43 into the slide rail 6 under the push rod 42, the retainer 10 fixes the new high beam headlight assembly 2, low beam headlight assembly 3 or high beam headlight assembly 4 into the fixing port 11 when it enters the slide rail 6, thus preventing direct falling and making it easier for the lock 9 to position and connect with it.

A slider 5 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the base 1. A slide rail 6 is installed at the connection between the slider 5 and the base 1. The slider 5 is connected to an adapter at the output end of an adjustment motor 7 installed on the rear side of the outer wall of the base 1 via a connecting shaft. A vision sensor 8 is installed on the upper side of the outer wall of the base 1. A locking device 9 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the slider 5. The adjustment motor 7, the vision sensor 8, and the locking device 9 are all connected to an on-board terminal via signal transmission. Fixers 10 are installed on both the left and right sides of the outer walls of the high beam group 1 2, low beam group 3 and high beam group 2 4. Fixers 10 are fixedly connected to the fixing port 11 provided on the front side of the outer wall of the base 1 by mechanical locking. A rotator 12 is installed at the connection between the locker 9 and the slider 1 5. Angle sensors 13 are installed at the connection between the rotator 12 and the locker 9 and the slider 1 5. Fixers 10 and angle sensors 13 are respectively connected to the vehicle terminal through signal transmission. Rotator 12 is connected to the adapter at the output end of the adjustment motor 7 through the connecting shaft. The fixture 10 consists of a latch 31, an electromagnetic unit 32, and a slider 33. A slide rail 34 is installed in the middle of the inner wall of the fixing port 11. A slider 33 is installed on the front side of the outer wall of the slide rail 34. A latch 31 is installed on the front side of the outer wall of the slider 33. The latch 31 engages with a groove provided in the inner wall of the fixing port 11. An electromagnetic unit 32 is installed at the connection between the latch 31 and the slider 33. The electromagnetic unit 32 is connected to a pressure sensor 35 embedded in the inner wall of the slide rail 34 through signal transmission. The electromagnetic unit 32 and the pressure sensor 35 are respectively connected to the vehicle terminal through signal transmission. Furthermore, when the vehicle is traveling on bumpy roads, the swaying of the vehicle body can cause a decrease in the stability of the high beam or low beam, resulting in a reduced ability to warn of obstacles and increasing the possibility of glare for oncoming drivers. During travel on smooth roads, the vehicle terminal disconnects the electromagnetic unit 32 from the external power supply, causing the latch 31 to engage with the groove on the inner wall of the fixing port 11, fixing the high beam group 1 2, low beam group 3, and high beam group 2 4 in their respective positions. When the vehicle is traveling on bumpy roads, the pressure sensor 35 located inside the slide rail 34 detects significant pressure fluctuations of the slider 33 on the slide rail 34. At this time, the vehicle terminal controls the electromagnetic unit 32 to connect to the external power supply to generate a thrust that pushes the latch 31 open, disengaging the latch 31 from the groove on the inner wall of the fixing port 11, restoring the mobility of the retainer 10, and controlling the adjustment motor 7 to output power. The adapter at the output end connects to slider 5 at high beam group 12, low beam group 3, and high beam group 24, allowing the adjusting motor 7 to simultaneously transmit power to slider 5 at high beam group 12, low beam group 3, and high beam group 24. This enables high beam group 12, low beam group 3, and high beam group 24 to move freely during travel on bumpy roads. Slider 33 drives the connected electromagnetic unit 32 and latch 31 to move up and down with the vehicle within slide rail 34. At the same time, slider 5 can move high beam group 12, low beam group 3, and high beam group 24, eliminating the impact of vehicle bumps on the lights. If there is left and right swaying, similar buffer structures can be added at the connection between latch 31 and high beam group 12, low beam group 3, and high beam group 24, and at the connection between slider 33 and slide rail 34, to eliminate the impact of left and right swaying.

[0027] Example 5: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 7 A headlight lens with high and low beam functions includes a base 1. A high beam lamp group 2 is installed on the front side of the outer wall of the base 1. A low beam lamp group 3 is installed on the left side of the outer wall of the high beam lamp group 2. A high beam lamp group 4 is installed on the left side of the outer wall of the low beam lamp group 3. A slider 5 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the base 1. A slide rail 6 is installed at the connection between the slider 5 and the base 1. The slider 5 is connected to an adapter at the output end of an adjustment motor 7 installed on the rear side of the outer wall of the base 1 via a connecting shaft. A vision sensor 8 is installed on the upper side of the outer wall of the base 1. A locking device 9 is installed at the connection between the high beam lamp group 2, the low beam lamp group 3, and the high beam lamp group 4 and the slider 5. The adjustment motor 7, the vision sensor 8, and the locking device 9 are all connected to an on-board terminal via signal transmission. The protective cover 25 is connected to the base 1 via a heat sink 36. A heat sink 37 is provided on the outer wall of the heat sink 36. A baffle 38 is installed at the connection between the heat sink 37 and the heat sink 36. The baffle 38 is connected to the adapter at the output end of the regulating motor 7 via a connecting shaft. A temperature sensor 39 is provided on the outer wall of the baffle 38 near the low beam headlight assembly 3. The temperature sensor 39 is connected to the regulating motor 7 and the vehicle terminal respectively via signal transmission. Furthermore, during driving, changes in ambient temperature can affect the temperature. Temperature sensor 39 monitors the temperature within the enclosed space comprised of base 1, protective cover 25, and heat sink 36. When the temperature exceeds 90℃, the vehicle terminal controls the regulating motor 7 to connect to the baffle 38. Driven by the regulating motor 7, the baffle 38 moves, opening the closed heat dissipation vent 37 to expel accumulated heat and prevent deformation or damage to plastic components such as base 1 due to heat buildup. When high beams (high beam group 1 2, low beam group 3, and high beam group 2 4) are provided individually or in combination, to avoid internal... The accumulation of heat can affect non-operating lamps. Without affecting high beam or low beam illumination, i.e., the height of the lamps providing illumination remains unchanged, the height of the non-operating high beam group 2, low beam group 3, or high beam group 4 is adjusted by controlling the slider 5 connected to the non-operating high beam group 2, low beam group 3, or high beam group 4 by the adjusting motor 7. This adjusts the height of the non-operating high beam group 2, low beam group 3, or high beam group 4 away from the operating lamps, preventing the heat generated by the operating lamps from affecting the non-operating lamps, reducing the accumulation of heat in the internal space, and thus improving the stability of the high beam or low beam.

[0028] Working principle: The vehicle collects road information through the vision sensor 8. When a vehicle appears in the oncoming lane, the vehicle terminal controls the high beam group 1 2 or high beam group 2 4 to stop operating and controls the low beam group 3 to operate, switching the high beam to low beam. Based on the vehicle model collected by the vision sensor 8, the vehicle terminal obtains the headlight height of the vehicle model from the database and compares it with the headlight height of the vehicle itself. To avoid the low beam of the vehicle interfering with the driver of the oncoming vehicle due to the height difference of the vehicle's headlights or the height difference caused by uphill or downhill road sections, the vehicle terminal controls the slider 1 5 connected to the low beam group 3 by the adjustment motor 7 to adjust the height of the low beam group 3. When a fault occurs in high beam group 12, low beam group 3, or high beam group 24, in order to prevent oncoming drivers from being dazzled when meeting oncoming traffic due to the inability to switch between high and low beams, the vehicle terminal receives monitoring data from the current sensor 30 at the connection between connector 29 and locker 9. When low beam group 3 is faulty or the light intensity is insufficient, the conversion motor 19 drives the telescopic shaft 17 at the front end of high beam group 12 and high beam group 24 to extend the light shield 16 to the front of the high beam light source 14, converting the high beam into low beam with a cutoff line. When high beam group 12 or high beam group 24 is faulty or the light intensity is insufficient, the conversion motor 19 drives the slider 24 to move on the slide rail 23, changing the distance between lens 22 and low beam light source 20, converting the low beam into high beam, thereby ensuring sufficient light intensity for both high and low beams and the ability to switch between high and low beams in an emergency. When the high beam group 12, low beam group 3, or high beam group 24 malfunctions, the connection between connector 29 and locking device 9 is disconnected. The motor 7 drives slider 15 to drop the faulty lamp from the replacement valve 28 below the base 1 into storage box 27. The replacement valve 28 above the base 1 then drops the new lamp from storage box 126 into slide rail 16. The locking device 9 connects the new lamp and connector 29 to complete the timely replacement, preventing the faulty lamp from affecting normal driving and the overall structural safety. When driving on bumpy roads, the connection between the electromagnetic unit 32 and the external power supply is used to release the fixed connection between the latch 31 and the fixing port 11, and to connect the slider 5 and the adjusting motor 7, so that the high beam group 1 2, the low beam group 3 or the high beam group 2 4 are in a movable state when bumpy, avoiding damage to the lamps and structural wear caused by shaking, thereby avoiding damage to the lamps and failure of the high and low beam switching function due to long-term bumpy driving, and extending the service life of the equipment.
