Description

Technical Field

[0001] This invention relates to the field of automotive lighting, specifically to an automotive headlight with hill-start adaptive lighting and its manufacturing equipment. Background Technology

[0002] Automotive headlights are devices installed on both sides of the front of a car for road lighting at night. They are also called car headlights. Automotive headlights are mainly composed of plastic lamp housings, plastic lamp covers, light sources, and reflectors.

[0003] While existing car headlights have the function of adjusting the beam direction, they often rely on manual adjustment by the user. Although matrix headlights offer rich adjustment functions, their cost is often high, making them more suitable for high-end models and not universally applicable. When a car is going uphill, the light tends to travel in a straight line, which means that the conditions on the slope before the incline are often not illuminated, creating blind spots and affecting driving safety. At the same time, the existing headlight adjustment function often requires changing the headlight direction, and its response is often slow, making it difficult to meet the needs of real-world applications.

[0004] Meanwhile, during the production process of automotive headlight covers, a reinforcing film needs to be coated on their surface to increase the rigidity and wear resistance of the cover. The existing coating method still largely relies on manual spraying. This method makes it difficult to ensure the uniformity of the coating during the spraying process. In addition, because the operator holds the cover during the spraying process, some areas may be blocked and not sprayed due to operator error, resulting in a decrease in the yield rate. Existing headlight cover spraying equipment often only sprays the outer end surface of the headlight cover and cannot spray both the inner and outer end surfaces of the headlight cover in one work process. Summary of the Invention

[0005] To overcome the above-mentioned technical problems, the present invention provides a headlight with ramp adaptive lighting function.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A car headlight with ramp adaptive lighting function includes a mounting bracket. A headlight cover is fixedly mounted at the front end of the mounting bracket, and a beam condenser is fixedly mounted at the rear end of the mounting bracket. A light source is fixedly mounted at the center of the beam condenser. A radar detector head is fixedly mounted on the mounting bracket. The headlight cover is processed into a long cylindrical shape. The sides of the headlight cover are coated with an opaque material. A beam splitter is rotatably mounted at the center of the headlight cover. The beam splitter is a light-reflecting lens.

[0008] The mounting bracket is used to install automotive headlights onto a vehicle. During headlight illumination, the light source emits light, which is then focused by the beam concentrater to illuminate the road ahead and projected from the front of the beam concentrater. While the vehicle is in motion, a radar sensor monitors the road conditions ahead. This radar sensor utilizes existing automotive technologies, employing lidar or millimeter-wave radar, effectively detecting terrain and obstacles. A small motor is integrated within the beam concentrater, with a drive shaft fixedly connected to a beam splitter. Each beam splitter is driven by a small motor, such as a Sieg Drive micro-motor with a diameter of up to 8mm, facilitating installation in the relatively confined space of the beam concentrater. When the radar sensor detects an uphill slope greater than 15 degrees, it notifies the vehicle's control terminal. The control terminal then instructs the drive shaft of the small motor within the beam concentrater to rotate the beam splitter, causing it to rotate 80 degrees. When light shines on the beam splitter (the lenses that make up the beam splitter are made of the same material as existing mirrors), the light is reflected on the beam splitter, thus changing the propagation path of the light. The light source has a width of 5mm, the beam splitter has a width of 20mm, and the distance from the light source to the midpoint of the beam splitter is 50mm. When the light from the light source shines on the beam splitter, it forms a light band between 15 and 22 degrees, thus illuminating the ramp. When driving on a flat road, the control terminal will send a command to make a small motor drive the beam splitter back to center, and the light enters from the side of the beam splitter. The substrate of the beam splitter is made of transparent glass, which does not affect the propagation of the light. Existing technologies often use multiple light sources to change the propagation path of the light. If the directional propagation of the light is also required, this method will result in a very complex lampshade structure, thereby increasing the manufacturing cost. However, the above technical solution will not make the lampshade structure more complex.

[0009] The present invention also provides a production apparatus for automotive headlights with hill-adaptive lighting function. This production apparatus is suitable for the above-mentioned automotive headlights with hill-adaptive lighting function, and can ensure the uniformity of spraying during the process of spraying a reinforcing film on the automotive headlight cover, and can spray the inner and outer end faces of the cover.

[0010] A production apparatus for automotive headlights with ramp-adaptive lighting function, comprising:

[0011] A fixed frame, on each side of which a drive roller is rotatably mounted, and on each side of which a drive pulley is fixedly installed;

[0012] A conveyor belt is provided to connect two drive pulleys on the same side of the drive roller, with one drive pulley on each side of the drive roller.

[0013] A loading device is mounted in the middle of two conveyor belts and is evenly distributed on the conveyor belts.

[0014] A spraying device, comprising a spraying ring frame, which is fixedly mounted on a fixed frame and surrounds the upper section of a conveyor belt. A spraying mechanism for spraying a front lamp cover is provided on the spraying ring frame.

[0015] During the painting process of automotive headlight covers, the headlight cover is placed on a loading device. A power source drives the rotation of a drive roller, which in turn drives a drive pulley. The drive pulley in turn drives a conveyor belt, which in turn moves the loading device. When the loading device moves the headlight cover to the middle of the painting ring, the painting mechanism moves in a circular motion along the painting ring. During this circular motion, the painting ring evenly paints the headlight cover. Compared to manual painting, the painting effect is more uniform. Compared to existing equipment, because the painting mechanism paints around the headlight cover, both the inner and outer sides of the headlight cover can be evenly painted, thus achieving a better painting effect.

[0016] In a further embodiment, the loading device includes a loading rod, with a placement part for placing the headlight cover fixedly installed in the middle of the loading rod. The lower end of the placement part is hollow, and the left and right ends of the loading rod are fixedly installed on the conveyor belt.

[0017] The headlight cover is placed in the mounting section of the loading mechanism, and it can move with the movement of the conveyor belt. The loading device has a very simple structure, is not only inexpensive but also very reliable and durable.

[0018] In a further embodiment, the loading device includes a loading support rod, a loading section, and a connecting mechanism. The loading section is positioned between two conveyor belts and has a through hole in the middle for mounting a headlight cover. A loading support rod is fixedly connected to each of the left and right sides of the loading section. A connecting mechanism is fixedly installed on the conveyor belt corresponding to the front and rear ends of the loading support rods. The connecting mechanism includes a connecting cover and a connecting spring. The connecting cover is fixedly installed on the conveyor belt, and the connecting cover and the ends of the loading support rods are fixedly connected by connecting springs. Multiple connecting springs are evenly arranged circumferentially around the ends of the loading support rods.

[0019] After prolonged use, conveyor belts will inevitably deform to some extent. To reduce the difficulty of placing the headlight cover flat due to conveyor belt deformation, a long loading rod is used to support the loading unit. This effectively prevents the loading unit from being misaligned when placing the headlight cover due to deformation of a certain part of the conveyor belt. However, when the loading rod is conveying to the drive pulley, the distance between two fixed points on the conveyor belt will change slightly. By connecting the loading rod and the connecting cover with a connecting spring, the end of the loading rod is allowed to move within the connecting cover, thereby offsetting the aforementioned changes in the conveyor belt.

[0020] In a further embodiment, the spraying mechanism includes a spraying ring plate, four rollers rotatably connected to the spraying ring plate, the four rollers being mounted on a spraying ring frame, a sliding plate fixedly connected to the spraying ring plate, a sliding groove formed on the sliding plate, a slider slidably connected in the sliding groove, a spraying rod mounted on the slider, a reciprocating ring fixedly mounted on the spraying ring frame, the inner side of the reciprocating ring having a circulating wave-shaped reciprocating groove, and the sliding plate being slidably connected to the reciprocating groove via a rod.

[0021] During the circular motion of the spraying mechanism around the spraying ring, a motor mounted on the spraying ring plate drives the rotation of rollers. The rollers, in turn, cause the spraying mechanism to move in a circular motion around the headlight cover. The spraying rod integrates the spraying mechanism of an existing paint gun and receives high-pressure gas mixed with coating paint through pipelines. Since existing paint guns struggle to ensure uniform paint density across all spray positions, the rods on the sliding plate slide against the reciprocating groove during the circular motion of the spraying mechanism around the spraying ring. This causes the spraying slider to reciprocate along the groove, simultaneously driving the spraying rod to reciprocate. This ensures that all areas sprayed by the spraying rod can effectively coat the headlight cover, improving the uniformity of the spraying process.

[0022] In a further embodiment, the spraying ring plate performs reciprocating circular motion along the spraying ring frame.

[0023] Because the spraying mechanism is connected to the pipeline that transports the high-pressure gas that mixes the paint, the aforementioned device can effectively prevent the gas from tangling.

[0024] In a further embodiment, a visual detection head is fixedly installed on the spraying ring plate.

[0025] The position of the loading device is observed by a vision sensor. When the loading device moves to the middle of the spraying ring, a signal can be sent to the relevant control system to stop the rotation of the drive roller, and then the headlight cover can be sprayed.

[0026] In a further embodiment, the spraying rod is slidably connected to the slider, and a spring is sleeved on the spraying rod. The spring is fixedly installed on one end of the spraying rod near the reciprocating ring and the sliding plate. An abutment ring plate is fixedly installed on the inner side of the reciprocating ring, and the abutment ring plate slides in contact with the spraying rod. The lower end of the abutment ring plate protrudes upward.

[0027] Because the headlight cover is concave, in order to achieve the same spraying effect when spraying the inside of the headlight cover as when spraying the outside, the spraying rod slides along the abutment ring plate. When the spraying rod moves to the lower end of the abutment ring plate, under the pressure of the abutment ring plate, the spraying rod will approach the headlight cover, so that the spraying position is closer to the inside of the headlight cover, thereby achieving a better spraying effect. At the same time, under the action of the spring, the spraying rod will always slide and stick to the abutment ring plate.

[0028] The spraying rod includes a main rod, which is slidably connected to the slider. A nozzle is rotatably connected to the end of the main rod away from the reciprocating ring. The nozzle and the main rod are connected by a flexible hose. A return spring is fixedly installed between the nozzle and the main rod. A crossbar is fixedly connected to the nozzle, and a toggle lever is fixedly installed on the slider corresponding to the crossbar.

[0029] As the spray bar approaches the headlight cover, the return spring's elasticity keeps the nozzle and main rod parallel. When the lever contacts the crossbar, the crossbar tilts the nozzle, allowing for proper spraying of the side of the beam splitter in the headlight cover without affecting the normal spraying of the rest of the headlight cover.

[0030] The beneficial effects of this invention are:

[0031] 1. This invention uses a radar detector to monitor road conditions ahead. When an uphill slope is detected, a small motor integrated in the headlight housing drives the beam splitter to rotate. The radar detector then notifies the control terminal inside the vehicle. The control terminal issues a command to drive the drive shaft of the small motor in the headlight housing to rotate the beam splitter, causing it to deflect. When light shines on the beam splitter, it is reflected, thus changing the light's propagation path and illuminating the uphill road. When driving on a flat road, the small motor drives the beam splitter back to center, and light enters from the side of the beam splitter. The substrate of the beam splitter is transparent and does not affect the propagation of light.

[0032] 2. In this invention, the spraying mechanism moves in a circular motion along the spraying ring. During this circular motion, the spraying ring evenly sprays the headlight cover. Compared to manual spraying, the spraying effect is more uniform. Compared to existing equipment, because the spraying mechanism sprays around the headlight cover, both the inner and outer sides of the headlight cover can be evenly sprayed, achieving a more comprehensive spraying effect while also effectively spraying the beam splitter.

[0033] 3. In this invention, when the lever and the crossbar come into contact, the crossbar will cause the nozzle to tilt. The tilting of the nozzle allows for good spraying of the side of the beam splitter in the headlight cover, while not affecting the normal spraying of the other parts of the headlight cover.

Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] To solve the technical problems proposed in this invention.

[0049] like Figures 1 to 3 As shown, the present invention provides a car headlight with ramp adaptive lighting function, including a mounting bracket 1. A headlight cover 11 is fixedly mounted on the front end of the mounting bracket 1, and a condenser cover 12 is fixedly mounted on the rear end of the mounting bracket 1. A light source 13 is fixedly mounted in the middle of the condenser cover 12. A radar detector head 14 is fixedly mounted on the mounting bracket 1. The headlight cover 11 is processed into a long cylindrical shape. The side of the headlight cover 11 is coated with an opaque material. A beam splitter 15 is rotatably mounted in the middle of the headlight cover 11. The beam splitter 15 is a lens that can reflect light.

[0050] It should be noted that the mounting bracket 1 is used to install the car headlight onto the car. During the illumination process of the car headlight, the light source 13 emits light, and the beam concentrater 12 focuses the light to illuminate forward and emits it from the front end of the headlight cover 11. During the car's movement, the radar detector 14 monitors the road conditions ahead. The radar detector is existing technology, using lidar or millimeter-wave radar currently used in automobiles, which can effectively detect terrain and obstacles. A small motor with a drive shaft fixedly connected to the beam splitter 15 is integrated in the headlight cover 11. This small motor can be a Sieg Drive micro motor with a diameter of up to 8mm, which is convenient for installation in the relatively small space of the beam concentrater 12. When the radar detector detects that the road ahead is on an uphill road with a slope greater than 15 degrees, it will notify the control terminal in the car. The control terminal will issue a command to make the drive shaft of the small motor in the headlight cover 11 drive the beam splitter 15 to rotate, thereby causing the beam splitter 15 to rotate 8 degrees. When light shines on the beam splitter 15 (the lenses that make up the beam splitter 15 are made of the same material as existing mirrors), 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 5mm, the beam splitter has a width of 20mm, and the distance from the light source to the midpoint of the beam splitter is 50mm. When the light from the light source shines on the beam splitter, a light band between 15 and 22 degrees will be formed, thereby illuminating the ramp. When driving on a flat road, the control terminal will send a command to make the small motor drive the beam splitter 15 back to the center. The light enters from the side of the beam splitter 15. The substrate of the beam splitter 15 is made of transparent glass, which will not affect the propagation of the light. Existing technologies often use multiple light sources to change the propagation path of the light. If the directional propagation of the light is also guaranteed, the lampshade structure will become very complex, thereby increasing the manufacturing cost. However, the above technical solution will not make the lampshade shape more complex.

[0051] like Figures 4 to 11 As shown, the present invention also provides a production apparatus for automotive headlights with ramp adaptive lighting function. This production apparatus is suitable for producing the above-mentioned automotive headlights with ramp adaptive lighting function. It can ensure the uniformity of spraying during the process of spraying a reinforcing film on the automotive headlight cover, and can spray the inner and outer end faces of the cover, so that the beam splitter 15 can also be effectively sprayed.

[0052] A production apparatus for automotive headlights with slope adaptive lighting function includes a fixed frame 2, on each side of the fixed frame 2 a drive roller 21 is rotatably mounted, and on each side of the drive roller 21 a drive pulley 22 is fixedly installed.

[0053] The conveyor belt 3 is used to connect two drive pulleys 22 on the same side of the drive roller 21. The conveyor belt 3 is provided with one drive pulley 22 on each side of the drive roller 21.

[0054] The loading device 4 is fixedly mounted in the middle of the two conveyor belts 3, and the loading device 4 is evenly distributed on the conveyor belts 3.

[0055] The spraying device 5 includes a spraying ring frame 51, which is fixedly mounted on the fixed frame 2. The spraying ring frame 51 surrounds the upper section of the conveyor belt 3, and a spraying mechanism 52 for spraying the front lamp cover 11 is provided on the spraying ring frame 51.

[0056] It should be noted that during the painting process of the car headlight cover 11, the car headlight cover 11 is placed on the loading device 4, and the drive roller 21 is rotated by the power source. The drive roller 21 rotates and drives the drive pulley 22 to rotate. The drive pulley 22 drives the conveyor belt 3 to move. The conveyor belt 3 drives the loading device 4 to move. When the loading device 4 moves the headlight cover 11 to the middle position of the painting ring 51, the painting mechanism 52 will move in a circle along the painting ring 51. At this time, the painting mechanism 52 will evenly paint the headlight cover 11. Compared with manual painting, the painting effect is more uniform. Compared with the existing equipment, because the painting mechanism 52 sprays around the headlight cover 11, both the inner and outer sides of the headlight cover 11 can be evenly painted. At the same time, the beam splitter 15 installed on the headlight cover 11 can also be effectively painted, thereby improving the service life of the beam splitter 15.

[0057] like Figure 4 As shown, the loading device 4 includes a loading rod 41, and a placement part 42 for placing the headlight cover 11 is fixedly installed in the middle of the loading rod 41. The lower end of the placement part 42 is hollow, and the left and right ends of the loading rod 41 are fixedly installed on the conveyor belt 3.

[0058] It should be noted that when the headlight cover 11 is placed in the placement part 42 of the loading mechanism, it can move with the movement of the conveyor belt 3. The loading device 4 has a very simple structure, is not only inexpensive but also very reliable and durable. The through hole in the middle of the placement part 42 is made of rubber, which can provide friction to fix the placement part 42.

[0059] like Figure 5 and Figure 6As shown, the loading device 4 includes a loading support rod 43, a loading part 44, and a connecting mechanism 45. The loading part 44 is located in the middle of two conveyor belts 3. The loading part 44 has a through hole in the middle for installing the headlight cover 11, and the inside of the through hole of the loading part 44 is made of rubber. A loading support rod 43 is fixedly connected to each of the left and right sides of the loading part 44. The connecting mechanism 45 is fixedly installed on the conveyor belt 3 corresponding to the front and rear ends of the loading support rod 43. 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 connecting cover 451 and the end of the loading support rod 43 are fixedly connected by the connecting spring 452. Multiple connecting springs 452 are evenly arranged around the end of the loading support rod 43.

[0060] It should be noted that after prolonged use, the conveyor belt 3 will inevitably deform to some extent. In order to reduce the difficulty in placing the headlight cover 11 flat due to the deformation of the conveyor belt 3, a longer loading rod 41 is used to support the loading part 44. This can effectively suppress the phenomenon that the loading part 44 is not properly positioned when placing the headlight cover due to the deformation of a certain part of the conveyor belt 3. However, when the loading rod 41 is conveying to the drive pulley 22, the distance between the two fixed points on the conveyor belt 3 will change slightly. By connecting the loading support rod 43 and the connecting cover 451 through the connecting spring 452, the end of the loading support rod 43 is allowed to move in the connecting cover 451, thereby offsetting the aforementioned changes in the conveyor belt 3.

[0061] like Figure 4 and Figure 5 , Figures 7 to 10 As shown, the spraying mechanism 52 includes a spraying ring plate 521, on which four rollers 522 are rotatably connected. The four rollers 522 are engaged on the spraying ring frame 51. A sliding plate 523 is fixedly connected to the spraying ring plate 521. A sliding groove 5231 is formed on the sliding plate 523. A slider 524 is slidably connected in the sliding groove 5231. A spraying rod 525 is installed on the slider 524. A reciprocating ring 511 is fixedly installed on the spraying ring frame 51. A reciprocating groove 5111 with a circulating wave shape is machined on the inner side of the reciprocating ring 5111. The sliding plate 523 is slidably connected to the reciprocating groove 5111 through a rod.

[0062] It should be noted that during the circular motion of the spraying mechanism 52 around the spraying ring 51, a motor installed on the spraying ring plate 521 drives the rotation of the roller 522. The roller 522, in turn, drives the spraying mechanism 52 to rotate around the headlight cover 11. The spraying rod 525 integrates the spraying mechanism 52 of an existing paint gun and receives high-pressure gas mixed with coating paint through a pipeline. Simultaneously, because existing spray guns struggle to ensure uniform paint density at all spray positions during the paint application process... Similarly, during the circular motion of the spraying mechanism 52 around the spraying ring 51, the rod on the sliding plate 523 will slide and connect with the reciprocating groove 5111, thereby causing the spraying slider 524 to slide back and forth along the sliding groove 5231. The spraying slider 524 will simultaneously drive the spraying rod 525 to reciprocate. In this way, during the spraying process of the car's headlight cover 11, the spraying rod 525 can spray all areas of the headlight cover 11, thereby improving the uniformity of the spraying process.

[0063] The spraying ring plate 521 reciprocates in a circular motion along the spraying ring frame 51.

[0064] It should be noted that, because the spraying mechanism 52 is connected to the pipeline that transports the high-pressure gas of the mixed paint, the above-mentioned device can effectively prevent the entanglement of the gas.

[0065] A visual detection head 6 is fixedly installed on the spraying ring plate 521.

[0066] It should be noted that by observing the position of the loading device 4 through the vision 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 drive roller 21, and then spray the headlight cover 11. During the spraying process, a peelable plastic film can be covered on the surface of the vision detection head 6 to protect the vision detection head 6.

[0067] like 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 on one end of the spraying rod 525 near the reciprocating ring 511 and the sliding plate 523. An abutment ring plate 512 is fixedly installed on the inner side of the reciprocating ring 511. The abutment ring plate 512 slides in contact with the spraying rod 525. The lower end of the abutment ring plate 512 protrudes upward.

[0068] It should be noted that, since the headlight cover 11 is concave, in order to achieve the same spraying effect as spraying the outer side when spraying the inner side of the headlight cover 11, the spraying rod 525 slides along the abutment ring plate 512. When the spraying rod 525 moves to the lower end of the abutment ring plate 512, under the pressure of the abutment ring plate 512, the spraying rod 525 will approach the headlight cover 11, so that the spraying position is closer to the inside of the headlight 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 stick to the abutment ring plate 512.

[0069] like Figures 7 to 10 As shown, the spraying rod 525 includes a main rod 5251, which is slidably connected to the slider 524. A nozzle 5252 is rotatably connected to the end of the main rod 5251 away from the reciprocating ring 511. The nozzle 5252 and the main rod 5251 are connected by a flexible hose. A return spring 5255 is fixedly installed between the nozzle 5252 and the main rod 5251. A crossbar 5253 is fixedly connected to the nozzle 5252, and a toggle lever 5254 is fixedly installed on the slider 524 corresponding to the crossbar 5253.

[0070] It should be noted that as the spray bar 525 approaches the headlight cover 11, the elastic force of the return spring 5255 will keep the nozzle 5252 and the main rod 5251 in a parallel state. When the toggle lever 5254 and the crossbar 5253 come into contact, the crossbar 5253 will cause the nozzle 5252 to tilt. The nozzle 5252 tilts and points to the side of the beam splitter 15. At this time, the side of the beam splitter 15 in the headlight cover 11 can be well sprayed without affecting the normal spraying of other parts of the headlight cover 11. The nozzle 5252 and the spray bar 525 in this invention integrate the existing spray gun mechanism. During the spraying process, the pressure is provided by an external air pump and connected to an external paint tank through a pipe to obtain the source of the reinforcing paint.

[0071] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0072] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0073] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention.
