Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamp structures, and more particularly to a tightly connected vehicle lamp structure. Background Art

[0002] When off-road vehicles are going on off-road adventures in the wild, they often face extremely complex road conditions, especially in areas that have not yet been developed and lack lighting infrastructure such as street lights. At this time, the lights installed on the top of the off-road vehicle are particularly important because they can provide a wider and brighter lighting area, allowing the driver to have an early insight into the road conditions ahead. Compared with the headlights of ordinary vehicles, the top lights of off-road vehicles are installed at a higher position, which can effectively reduce the obstruction of light by obstacles such as vehicles in front and terrain undulations, thereby giving the driver a more distant and comprehensive field of vision. In order to meet the lighting needs of off-road vehicles under different road conditions, the top lights must also have the function of adjusting the angle in the vertical direction to ensure the best lighting effect.

[0003] In the prior art, the headlight is usually connected to the base by a hinge, and then a manual or electric mechanism is used to adjust the vertical angle of the headlight. However, after the adjustment is completed, the headlight must be tightly connected to the base with a nut or other fastening device to minimize the problem of the headlight angle deviation caused by vibration during the driving of the off-road vehicle. This operation method is not only cumbersome, but also often has an unsatisfactory stabilization effect when facing strong bumps and vibrations, and it is difficult to completely prevent the angle change.

[0013] Compared with the prior art, the advantages of the present invention are as follows: (1) When the headlight of the present invention is in operation, the lock plate is inserted into a lock groove. Since the lock plate, the lock platform, the slide bar and the base shell do not move relative to each other, the base shell and the headlight are tightly connected to the cross bar, thereby preventing the vertical angle between the base shell and the headlight from changing due to vehicle vibration.

[0014] (2) When the present invention needs to adjust the angle of the headlight in the vertical direction, the turntable of the angle adjustment component is rotated, the arc platform moves in the arc hole, the lever drives the locking platform to move downward along the slide bar, and the locking plate is disengaged from the locking groove. When the base shell and the headlight are adjusted to a suitable angle in the vertical direction, the turntable is released, and the spring provides elastic force to drive the locking platform to rise.

[0015] (3) The present invention provides two modes of manual adjustment and electric adjustment, which are used to adjust the vertical angle of the vehicle lamp; the self-locking button is pressed to extend the telescopic shaft of the self-locking button, drive the push plate and the wedge block to move toward the direction of the cover plate, the wedge block contacts the cover plate, and the wedge block drives the cover plate to move downward, so the fixed groove locks the lever, so the arc platform no longer moves in the arc hole, and at the same time the cover plate and the locking platform are synchronously lowered, and the locking plate is disengaged from the locking groove; the motor 1 is continuously powered to rotate the second group of gears 2 and gear 1, the turntable and the arc platform rotate synchronously, and since the lever is locked in the fixed groove, there is no phase movement between the lever, the cover plate, the locking platform, the sliding rod and the base shell, and the base shell rotates synchronously with the turntable, so when the rotating shaft of the motor 1 rotates, the base shell and the vehicle lamp can rotate synchronously, and the response is rapid, so as to realize the function of quickly adjusting the vertical angle of the vehicle lamp.

[0016] (4) The present invention pushes the second hand wheel to make the sliding shaft slide on the base, and the push plate pushes the sub-plate and the insertion rod to move in the direction away from the circular lock ring, so that the locking pin is disengaged from the locking hole, and the base can be rotated, thereby adjusting the horizontal angle between the base shell and the headlight; loosening the second hand wheel, the second spring provides elastic force to drive the insertion rod to move in the direction of the circular lock ring, so that the locking pin is reinserted into the locking hole, thereby realizing the function of adjusting the horizontal angle of the headlight.

[0017] (5) The present invention starts the motor 2 in the forward direction, and the threaded section of the composite screw drives the pin table and the slide seat to move, so that the two light assemblies close to the motor 2 and the two light assemblies far from the motor 2 move toward the middle at the same time, and the spacing between the five light assemblies is always equal, so that the light of the five light assemblies is more concentrated; when the motor 2 is started in the reverse direction, the two light assemblies close to the motor 2 and the two light assemblies far from the motor 2 move outward at the same time, so that the light of the five light assemblies is more dispersed.

DETAILED DESCRIPTION

[0033] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0034] Example 1: Please refer to Figure 1-8Structural schematic diagram, the present invention provides the following technical solutions: a tightly connected vehicle lamp structure, including a vehicle lamp assembly, the vehicle lamp assembly including a base 1, a cross bar 2 is fixedly provided on the base 1, a base shell 3 is rotatably connected to the outside of the cross bar 2 through a damping bearing 4, and a vehicle lamp 5 is provided at the front of the base shell 3. Specifically, through the damping bearing 4, the base shell 3 rotates with the vehicle lamp 5 on the cross bar 2, thereby adjusting the angle of the vehicle lamp 5 in the vertical direction.

[0035] Two groups of angle adjustment components are symmetrically arranged on both sides of the base shell 3, and each group of angle adjustment components includes a turntable 6 rotatably arranged on the side surface of the base shell 3. Four arc holes 301 are arranged on both sides of the base shell 3. Four arc platforms 7 passing through the four arc holes 301 are fixed on the side of the turntable 6, and the arc of the arc hole 301 is longer than the arc of the arc platform 7. Two hook platforms 8 are arranged on the arc platform 7 near the front of the base shell 3. There are tension springs 9 between the hook platforms 8 and the base shell 3. The side of the lower arc platform 7 is vertically connected with a lever 10. The lower part of the lever 10 contacts with a locking platform 11, and the two ends of the locking platform 11 slide respectively. It is arranged on the slide bar 12, and the slide bar 12 is fixed on the inner bottom surface of the base shell 3. A spring 13 is sleeved on the outer side of the slide bar 12. The two ends of the spring 13 are respectively connected to the lock platform 11 and the base shell 3. A lock plate 14 is vertically arranged above the lock platform 11. A lock disk 15 is arranged on the cross bar 2 and located inside the base shell 3. A plurality of lock grooves 1501 for locking the lock plate 14 are evenly distributed on the cylindrical surface of the lock disk 15. The width of the lock plate 14 is equal to the width of the lock groove 1501. A groove 1101 in contact with the lever 10 is provided on the lock platform 11, and the bottom surface of the groove 1101 is composed of an inclined surface, a bottom plane and an inclined surface in sequence.

[0036] Specifically, the upper surface of the lock plate 14 is provided with a chamfer to facilitate the insertion of the lock plate 14 into the lock groove 1501. When the headlight 5 is in operation, the two tension springs 9 are both in a stretched state, and the stretched lengths of the two tension springs 9 are the same, so the arc platform 7 is in a central position in the corresponding arc hole 301, and at the same time, the spring 13 provides elastic force to make the lock platform 11 in an upper position, and the lever 10 contacts the bottom plane of the groove 1101. At this time, the lock plate 14 is inserted into a lock groove 1501. Since there is no phase movement between the lock plate 14, the lock platform 11, the slide bar 12 and the base shell 3, the base shell 3 and the headlight 5 are tightly connected to the cross bar 2 to prevent the base shell 3 and the headlight 5 from changing their angles in the vertical direction due to vehicle vibration.

[0037] When the angle of the headlight 5 in the vertical direction needs to be adjusted, the turntable 6 is rotated. Since the locking plate 14 is inserted into a locking groove 1501, the base shell 3 does not rotate, so the turntable 6 rotates on the side surface of the base shell 3, the arc platform 7 moves in the arc hole 301, the length of one tension spring 9 is stretched, the length of the other tension spring 9 is contracted, and the lever 10 transitions from the bottom plane of the groove 1101 to the inclined surface. The lever 10 drives the locking platform 11 to move downward along the slide bar 12, and the spring 13 is compressed. When the arc platform 7 moves to contact the end of the arc hole 301, the locking platform 11 moves to the lower position along the slide bar 12, and the locking plate 14 is separated from the locking groove 1501, so the base shell 3 is no longer locked on the cross bar 2. The turntable 6 is continuously rotated, and the arc platform 7 rotates synchronously with the base shell 3. During this process, due to the damping force generated by the damping bearing 4, the base shell 3 is subjected to a torsional force in the opposite direction of its rotation. The arc platform 7 and the tension spring 9 exert a torsional force in the same direction of its rotation on the base shell 3. The two tension springs 9 are respectively kept in the state of length extension and length contraction, even if the locking plate 14 remains in the state of being separated from the locking groove 1501. When the base shell 3 and the headlight 5 are adjusted to a suitable angle in the vertical direction, the turntable 6 is released, and the two tension springs 9 are restored to the state of equal length at the same time. The arc platform 7 moves back to the middle position of the corresponding arc hole 301, and the lever 10 returns from the inclined surface of the groove 1101 to its bottom plane. The spring 13 provides elastic force to drive the locking platform 11 to rise, and the locking platform 11 rises synchronously with the locking plate 14. The locking plate 14 is reinserted into a locking groove 1501, so that the base shell 3 and the headlight 5 are tightly locked again. Connected to the cross bar 2; in the process of inserting the lock plate 14 into the lock slot 1501, the chamfered surface on the upper surface of the lock plate 14 enters the lock slot 1501 first. If the lock plate 14 does not fully enter and align with the lock slot 1501, the chamfered surface of the lock plate 14 contacts the edge of the lock slot 1501. Due to the elastic force of the spring 13, the base shell 3 rotates slightly, so that the lock plate 14 is fully aligned with the lock slot 1501, so the lock plate 14 will also squeeze into the lock slot 1501, completing the locking of the base shell 3.

[0038] Considering that the locking plate 14 may be located between the two locking grooves 1501 during the process of being inserted into the locking grooves 1501, the locking plate 14 is in contact with the cylindrical surface of the locking plate 15 and does not enter the locking grooves 1501. A connecting plate 16 is connected between the upper arc platforms 7 of the two groups of angle adjustment components, and the locking grooves 1501 on the locking plates 15 of the two groups of angle adjustment components are arranged alternately, that is, the middle symmetric plane of two adjacent locking grooves 1501 of the first group of angle adjustment components coincides with the middle plane of one locking groove 1501 of the second group of angle adjustment components, and the width of the locking groove 1501 is equal to the side distance between the two adjacent locking grooves 1501.

[0039] Specifically, when the rotating disk 6 of one set of angle adjustment components is turned, the power is transmitted through the arc platform 7 and the connecting plate 16, and the rotating disk 6 of the other set of angle adjustment components rotates synchronously. When the locking plates 14 of the two sets of angle adjustment components move upward, since the locking grooves 1501 are arranged in a staggered manner, the upper surface chamfer of the locking plate 14 of one set of angle adjustment components must enter the corresponding locking groove 1501, so that the base shell 3 and the lamp 5 are locked on the crossbar 2.

[0040] When the locking grooves 1501 on the locking plates 15 of the two sets of angle adjustment components are arranged in the same manner, if the locking plate 14 is aligned with the middle position of the two locking grooves 1501 during the rising process, and other technical means are used to make the locking plate 14 enter the locking groove 1501, the maximum distance that the base shell 3 slightly rotates is equal to the width of the locking plate 14. When the locking grooves 1501 on the locking plates 15 of the two angle adjustment components are arranged in a staggered manner, the maximum distance that the base shell 3 slightly rotates during the process of the locking plate 14 entering the locking groove 1501 is equal to half the width of the locking plate 14. Therefore, the staggered arrangement of the locking grooves 1501 on the two locking plates 15 can effectively shorten the angle of slight rotation of the base shell 3 when the base shell 3 is locked.

[0041] Both sets of angle adjustment components also include a gear 17 fixed on the turntable 6, and a gear 2 18 is meshed below the gear 17. The gear 2 18 of the first set of angle adjustment components is fixed on a rotating shaft 19, which is rotatably arranged on the base 1, and a hand wheel 1 20 is arranged at the end of the rotating shaft 19 passing through the base 1. The gear 2 18 of the second set of angle adjustment components is connected to the rotating shaft of a motor 1 21, and the motor 1 21 is fixed on the base 1.

[0042] Specifically, if manual adjustment is adopted, the motor 1 21 is powered off, and the hand wheel 1 20 is manually rotated, and the hand wheel 1 20 drives the rotating shaft 19 to rotate synchronously, and then the power is transmitted through the gear 2 18 and the gear 1 17 of the first group of angle adjustment components to rotate the turntable 6 of the first group of angle adjustment components. If electric adjustment is adopted, the motor 1 21 is powered on, and the motor 1 21 drives the gear 2 18 and the gear 1 17 of the second group of angle adjustment components to rotate, so that the turntable 6 of the second group of angle adjustment components rotates. After the base shell 3 is adjusted to the required angle, the motor 1 21 is powered off, and the base shell 3 is automatically locked.

[0043] Taking into account that when the angle of the base shell 3 in the vertical direction needs to be quickly adjusted electrically, the base shell 3 needs to be able to rotate quickly, a covering plate 22 is provided above the locking platform 11 of the two sets of angle adjustment components, and a fixed groove 2201 is provided in the covering plate 22 for clamping the lever 10, and the width of the fixed groove 2201 is equal to the diameter of the lever 10, and the edges on both sides of the fixed groove 2201 are provided with chamfers for facilitating the clamping of the lever 10; an end cover 23 is provided at the rear of the base shell 3, and a self-locking button 24 is provided on the end cover 23, and the telescopic shaft of the self-locking button 24 passes through the end cover 23 and enters the interior of the base shell 3, and a push plate 25 is provided at the end of the telescopic shaft of the self-locking button 24, and two wedge blocks 26 for respectively driving the two covering plates 22 are provided on the upper part of the push plate 25.

[0044] When the self-locking button 24 is pressed, the telescopic axis of the self-locking button 24 is extended, and when the self-locking button 24 is pressed again, the telescopic axis of the self-locking button 24 is shortened.

[0045] Specifically, when the telescopic shaft of the self-locking button 24 is shortened, the wedge block 26 does not contact the cover plate 22. When the base shell 3 needs to be adjusted quickly and electrically, the self-locking button 24 is pressed to extend the telescopic shaft of the self-locking button 24, driving the push plate 25 and the wedge block 26 to move toward the cover plate 22, and the wedge block 26 contacts the cover plate 22, and the wedge block 26 drives the cover plate 22 to move downward, so the fixed groove 2201 locks the lever 10, so the arc platform 7 no longer moves in the arc hole 301, and at the same time, the cover plate 22 and the locking platform 11 are synchronously lowered, and the locking plate 14 is separated from the locking groove 1501. The motor 21 is continuously powered to rotate the second group of gears 2 18 and gear 17, and the turntable 6 and the arc table 7 rotate synchronously. Since the lever 10 is locked in the fixed groove 2201, there is no phase shift between the lever 10, the cover plate 22, the locking table 11, the slide bar 12 and the base shell 3. The base shell 3 rotates synchronously with the turntable 6. Therefore, when the rotating shaft of the motor 21 rotates, the base shell 3 and the car light 5 can rotate synchronously, and the response is rapid.

[0046] The working principle of a tightly connected vehicle lamp structure provided by the present invention is as follows: when the vehicle lamp 5 is in operation, the two tension springs 9 of the two groups of angle adjustment components are both in a stretched state, and the stretched lengths of the two tension springs 9 are the same, so the arc platform 7 is in a central position in the corresponding arc hole 301, and at the same time, the spring 13 provides elastic force, so that the locking platform 11 of one group of angle adjustment components is in an upper position, and the lever 10 contacts the bottom plane of the groove 1101. At this time, the locking plate 14 is inserted into a locking groove 1501. Since there is no phase movement between the locking plate 14, the locking platform 11, the sliding rod 12 and the base shell 3, the base shell 3 and the vehicle lamp 5 are tightly connected to the cross bar 2, so as to avoid the change of the angle between the base shell 3 and the vehicle lamp 5 in the vertical direction due to the vibration of the vehicle. At the same time, the locking plate 14 of the other group of angle adjustment components is located between the two locking grooves 1501, that is, the locking plate 14 contacts the cylindrical surface of the locking plate 15.

[0047] When the angle of the headlight 5 in the vertical direction needs to be adjusted manually, the motor 121 is powered off, and the hand wheel 120 is manually rotated. The hand wheel 120 drives the rotating shaft 19 to rotate synchronously, and then the power is transmitted through the gear 218 and the gear 17 of the first group of angle adjustment components to rotate the turntable 6 of the first group, and the power is transmitted through the arc platform 7 and the connecting plate 16 to rotate the turntable 6 of the second group of angle adjustment components synchronously. Since the base shell 3 and the headlight 5 are tightly connected to the cross bar 2 at this time, the turntables 6 of the two groups of angle adjustment components rotate on the side surface of the base shell 3. The arc platform 7 of the angle adjustment component that produces the locking effect moves in the arc hole 301, the length of one tension spring 9 is stretched, and the length of the other tension spring 9 is contracted, and the lever 10 transitions from the bottom plane of the groove 1101 to the inclined surface, and the lever 10 drives the locking platform 11 to move downward along the slide bar 12, and the spring 13 is compressed. When the arc platform 7 moves to contact the end of the arc hole 301, the locking platform 11 moves to the lower position along the slide bar 12, and the locking plate 14 is disengaged from the locking groove 1501, so the base shell 3 is no longer locked on the cross bar 2. The hand wheel 20 is continuously turned, and the turntable 6 and the arc platform 7 rotate synchronously with the base shell 3. In this process, due to the damping force generated by the damping bearing 4, the base shell 3 is subjected to a torsional force in the opposite direction of its rotation. The arc platform 7 and the tension spring 9 exert a torsional force in the same direction of its rotation on the base shell 3, and the two tension springs 9 are respectively kept in the state of length extension and length contraction, that is, the locking plate 14 is kept in the state of disengagement from the locking groove 1501.

[0048] When the base shell 3 and the headlight 5 are adjusted to a suitable angle in the vertical direction, the hand wheel 1 20 is released, and the two tension springs 9 of the two groups of angle adjustment components are restored to a state of equal length at the same time, the arc platform 7 moves back to the middle position of the corresponding arc hole 301, and the lever 10 returns to its bottom plane from the inclined surface of the groove 1101. The spring 13 provides elastic force to drive the locking platform 11 to rise, and the locking platform 11 rises synchronously with the locking plate 14. Since the locking grooves 1501 are staggered, the locking plate 14 of one group of angle adjustment components must re-enter the corresponding locking groove 1501, so the base shell 3 and the headlight 5 are tightly connected to the crossbar 2 again.

[0049] During the ascending process of the locking plates 14 of the two angle adjustment components, if the two locking plates 14 are not completely aligned with the locking grooves 1501, but the chamfered surface of the upper surface of the locking plate 14 of one of the angle adjustment components enters the locking groove 1501, the chamfered surface of the locking plate 14 contacts the edge of the locking groove 1501, and due to the elastic force of the spring 13, the base shell 3 rotates slightly, so that the locking plate 14 is completely aligned with the locking groove 1501, so the locking plate 14 will also squeeze into the locking groove 1501, completing the locking of the base shell 3. At the same time, because the locking grooves 1501 on the locking plates 15 of the two angle adjustment components are staggered, the maximum distance of the slight rotation of the base shell 3 is equal to half the width of the locking plate 14, so the angle of slight rotation of the base shell 3 when the base shell 3 is locked can be effectively shortened.

[0050] When the angle of the headlight 5 in the vertical direction needs to be electrically adjusted, the hand wheel 20 is free from force, the motor 21 is energized, and the motor 21 drives the gear 2 18 and the gear 17 of the second group to rotate, so that the turntable 6 of the second group rotates. At the same time, according to the same principle as above, after the base shell 3 is adjusted to the required angle, the motor 21 is powered off and the base shell 3 is automatically locked.

[0051] When it is necessary to quickly electrically adjust the angle of the base shell 3 in the vertical direction, the self-locking button 24 is pressed to extend the telescopic shaft of the self-locking button 24, driving the push plate 25 and the wedge block 26 to move in the direction of the covering plate 22. The wedge block 26 contacts the covering plate 22, and the wedge block 26 drives the covering plate 22 to move downward, so the fixed groove 2201 locks the lever 10, so the arc platform 7 no longer moves in the arc hole 301, and at the same time, the covering plate 22 and the locking platform 11 are synchronously lowered, and the locking plate 14 is disengaged from the locking groove 1501. The motor 21 is continuously powered to rotate the second group of gears 2 18 and gear 17, and the turntable 6 and the arc table 7 rotate synchronously. Since the lever 10 is locked in the fixed groove 2201, there is no phase shift between the lever 10, the cover plate 22, the locking table 11, the slide bar 12 and the base shell 3. The base shell 3 rotates synchronously with the turntable 6. Therefore, when the rotating shaft of the motor 21 rotates, the base shell 3 and the car light 5 can rotate synchronously, and the response is rapid.

[0052] Example 2: Please refer to Figure 9-11 Structural schematic diagram, based on the specific embodiment 1, the difference of this embodiment is that: considering the need to adjust the horizontal angle of the headlight 5, a slide 27 is rotatably connected to the bottom of the base 1, and a vertical shaft 28 is vertically connected to the top of the slide 27. The vertical shaft 28 passes through the base 1, and a circular lock ring 29 is connected to the vertical shaft 28. The cylindrical surface of the circular lock ring 29 is evenly provided with a plurality of lock holes 2901. A support plate 30 is provided on the base 1 and located on the side of the circular lock ring 29. A plug rod 31 is slidably provided on the support plate 30. A locking pin 3101 for inserting into the locking hole 2901 is provided at one end of the plug rod 31, and the other end of the plug rod 31 is connected to the side of the base 1. A spring 2 32 is connected between the walls, a sub-plate 33 is provided above the insertion rod 31, and a bevel gear 1 34 is provided at the upper end of the vertical shaft 28; a sliding shaft 35 is slidably provided on the base 1 and located above the vertical shaft 28, and there is a sliding fit between the base 1 and the sliding shaft 35, so that the sliding shaft 35 can slide on the base 1 while rotating, and the end of the sliding shaft 35 extends to the outside of the base 1, and a hand wheel 2 36 is connected to the end of the sliding shaft 35, a push plate 37 for driving the sub-plate 33 to move is provided on the sliding shaft 35, and a bevel gear 2 38 for meshing with the bevel gear 1 34 is also provided on the sliding shaft 35.

[0053] When the lamp 5 is in operation, the spring 2 32 provides elastic force to insert the lock pin 3101 on the plug rod 31 into a lock hole 2901. Since the base 1, the support plate 30, the plug rod 31, the circular lock ring 29, the vertical shaft 28 and the slide 27 do not move relative to each other, the base 1 is locked on the slide 27 and does not rotate. When the horizontal angle of the base shell 3 needs to be adjusted, the hand wheel 2 36 is pushed to make the sliding shaft 35 slide on the base 1, and the push plate 37 pushes the sub-plate 33 and the plug rod 31 to move away from the circular lock ring 29, and the lock pin 3101 is disengaged from the lock hole 2901, and the base 1 can be rotated, thereby adjusting the horizontal angle of the base shell 3 and the lamp 5. The hand wheel 2 36 is continuously pushed to make the bevel gear 2 38 mesh with the bevel gear 1 34, and then the hand wheel 2 36 is rotated to make the bevel gear 2 38 rotate around the bevel gear 1 34, so that the base 1 rotates and the horizontal angle of the base 1 is adjusted. When the hand wheel 2 36 is released, the spring 2 32 provides elastic force to drive the insertion rod 31 to move toward the circular locking ring 29 , so that the locking pin 3101 is reinserted into the locking hole 2901 .

[0054] Example 3: Please refer to Figure 12-14 Structural schematic diagram, based on the specific embodiment 2, the difference of this embodiment is that: there are five headlight assemblies, and the five headlight assemblies are all installed on the crossbeam 39, and the crossbeam 39 is fixed on the top of the vehicle; a composite screw 40 is slidably and rotatably provided in the crossbeam 39, and four groups of threaded segments are arranged on the composite screw 40 in sequence, the pitch of the threaded segments at both ends is twice the pitch of the two middle groups of threaded segments, and the threaded segments located on both sides of the symmetry plane of the composite screw 40 have opposite rotation directions, a pin 41 is provided at the bottom of the slide 27, the slide 27 of the middle headlight assembly is fixed on the crossbeam 39, and the slides 27 of the remaining four headlight assemblies are slidably arranged on the crossbeam 39, and the pin 41 at the bottom of the slides 27 of these four headlight assemblies are respectively inserted into the four groups of threaded segments; a gear three 42 is provided at the end of the composite screw 40, and a gear four 43 is meshed above the gear three 42, and the gear four 43 is fixed on the rotating shaft of the motor two 44, and the motor two 44 is fixed on the crossbeam 39.

[0055] In the original state, the five lamp assemblies are spaced at equal distances. The motor 2 44 is started, and the motor 2 44 starts the gear 43 to rotate. The power is transmitted through the gear 3 42 to rotate the composite screw 40. The threaded section of the composite screw 40 drives the pin 41 and the slide 27 to move. The two lamp assemblies close to the motor 2 44 and the two lamp assemblies far from the motor 2 44 move toward the middle at the same time. The movement speed of the lamp assemblies at both ends is twice that of the two lamp assemblies in the middle. Therefore, the spacing of the five lamp assemblies is always equal, making the illumination of the five lamp assemblies more concentrated. When it is necessary to disperse the light sources of the five lamp assemblies, the motor 2 44 is started in the reverse direction. In the reverse process of the above principle, the two lamp assemblies close to the motor 2 44 and the two lamp assemblies far from the motor 2 44 move outward at the same time.

[0056] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
