DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figures 1 to 11 As shown: a vehicle lamp with a protective structure, comprising a mounting plate 1, a mounting groove 11 is opened on the mounting plate 1, a lamp bead 2 is arranged in the mounting groove 11, a lamp cover 3 is arranged on one side of the mounting plate 1, the mounting groove 11 has at least two, the lamp bead 2 has two, the two lamp bead 2 is respectively for low beam and high beam, the two lamp beads 2 are respectively mounted in the two mounting grooves 11, the outside of the lamp bead 2 is also sleeved with a sealing ring 21, a protective cover 4 for protecting the lamp bead 2 is arranged on the other side of the mounting plate 1, the protective cover 4 has two, the two protective covers 4 are respectively covered on the outside of the two lamp beads 2, a telescopic mechanism 5 is arranged in the protective cover 4, the telescopic mechanism 5 includes a telescopic structure 51 for receiving and extending the lamp bead 2 into and out of the protective cover 4, a connecting plate 52 and a rear cover plate 53 are respectively arranged at both ends of the telescopic structure 51, the connecting plate 52 is connected to the lamp bead 2, and the rear cover plate 53 is connected to the protective cover 4.

[0032] Under normal conditions, the telescopic structure 51 pushes the connecting plate 52 toward the mounting plate 1, so that the lamp bead 2 extends out from the protective cover 4, and the sealing ring 21 around the lamp bead 2 abuts against the mounting plate 1, so that the lamp bead 2 maintains normal function. When a car collides during driving, the lampshade 3 at the front end of the car is crushed by pressure, which can easily cause damage to the lamp bead 2. Once the lamp bead 2 is damaged, the maintenance cost will increase. Therefore, a telescopic mechanism 5 is provided. When the car rear-ends the front car, the telescopic structure 51 works to pull the connecting plate 52 toward the inside of the protective cover 4, and the connecting plate 52 drives the lamp bead 2 to be retracted into the protective cover 4. The protective cover 4 has a certain rigidity, so the protective cover 4 is not easy to deform, and can protect the lamp bead 2 inside the protective cover 4. If the collision does not cause damage to the headlight, the telescopic mechanism 5 is reset to reset the lamp bead 2 to the lampshade 3, thereby protecting the lamp bead 2 during the collision, reducing the degree of damage to the headlight and reducing the maintenance cost.

[0033] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown: the telescopic structure 51 includes a telescopic platform 511, which is connected to the connecting plate 52. A first driving structure 512 for driving the telescopic platform 511 to move is arranged on one side of the telescopic platform 511. A first connecting rod 513 and a second connecting rod 514 are arranged between the first driving structure 512 and the telescopic platform 511. The middle part of the first connecting rod 513 and the middle part of the second connecting rod 514 are axially connected, so that the first connecting rod 513 and the second connecting rod 514 are in an X shape. The two ends of the first connecting rod 513 are respectively connected to the telescopic platform 511 and the first driving structure 512, and the two ends of the second connecting rod 514 are respectively connected to the telescopic platform 511 and the first driving structure 512.

[0034] The front space of the car is limited, and the space for installing the headlights is even more limited. Therefore, the volume of the protective cover 4 and the telescopic mechanism 5 needs to be small enough to be installed on the car. The telescopic platform 511, the first driving structure 512, the first connecting rod 513 and the second connecting rod 514 form a scissor-type lifting form. When the lamp bead 2 is in a state of extending out of the protective cover 4, the first connecting rod 513 and the second connecting rod 514 are in a state of being close to each other. At this time, the first connecting rod 513 and the second connecting rod 514 maximize the distance between the telescopic platform 511 and the first driving structure 512. When the lamp bead 2 needs to be put into the protective cover 4, the first driving structure 512 drives the first connecting rod 513 and the second connecting rod 514 to rotate in a direction away from each other. At this time, the first connecting rod 513 and the second connecting rod 514 are folded, so that the distance between the telescopic platform 511 and the first driving structure 512 is minimized. At this time, the telescopic structure 51 occupies the smallest space, so that the volume of the headlight installed with the protective cover 4 and the telescopic mechanism 5 is small, which is convenient for installation on the car.

[0035] Reference Figure 5, Figure 6 and Figure 7 As shown: the telescopic platform 511 includes a first rectangular frame 5111, the first rectangular frame 5111 is connected to the connecting plate 52, a sliding rod 5112 is arranged in the first rectangular frame 5111, and the two ends of the sliding rod 5112 are respectively connected to the two ends of the first rectangular frame 5111, and first auxiliary rods 5113 are symmetrically arranged on both sides of the sliding rod 5112, and the two ends of the first auxiliary rod 5113 are respectively connected to the two ends of the first rectangular frame 5111, and a first moving seat 5114 and a second moving seat 5115 are slidably arranged on the sliding rod 5112, and the first driving structure 512 includes a second rectangular frame 5121, and the second rectangular frame 5121 is connected to the rear cover plate 53, and a double-headed screw 5122 is arranged in the second rectangular frame 5121, and the double-headed screw 512 2 are respectively connected to the two ends of the second rectangular frame 5121, two second auxiliary rods 5123 are symmetrically arranged on both sides of the double-headed screw 5122, and the two ends of the second auxiliary rods 5123 are respectively connected to the two ends of the second rectangular frame 5121, a third moving seat 5124 and a fourth moving seat 5125 are arranged on the double-headed screw 5122, and the third moving seat 5124 and the fourth moving seat 5125 are symmetrically arranged about the middle surface of the double-headed screw 5122, and a motor 5126 is arranged at one end of the double-headed screw 5122, two ends of the first connecting rod 513 are respectively connected to the first moving seat 5114 and the third moving seat 5124, and two ends of the second connecting rod 514 are respectively connected to the second moving seat 5115 and the fourth moving seat 5125.

[0036] When the telescopic mechanism 5 stores the lamp bead 2 into the protective cover 4, the motor 5126 works to drive the double-headed screw 5122 to rotate, and the double-headed screw 5122 makes the third moving seat 5124 and the fourth moving seat 5125 move away from each other, and the third moving seat 5124 and the fourth moving seat 5125 increase the angle between the same end of the first connecting rod 513 and the second connecting rod 514, and the other ends of the first connecting rod 513 and the second connecting rod 514 respectively push the first moving seat 5114 and the second moving seat 5115 away from each other along the sliding rod 5112, and because the first driving structure 512 is fixedly connected to the rear cover plate 53, the first rectangular frame 5111 gradually approaches the second rectangular frame 51 21. When the telescopic mechanism 5 extends the lamp bead 2 out of the protective cover 4, the motor 5126 drives the double-headed screw 5122 to rotate, and the double-headed screw 5122 makes the third movable seat 5124 and the fourth movable seat 5125 approach each other, and the third movable seat 5124 and the fourth movable seat 5125 reduce the angle between the same end of the first connecting rod 513 and the second connecting rod 514, and the other ends of the first connecting rod 513 and the second connecting rod 514 respectively drive the first movable seat 5114 and the second movable seat 5115 to approach each other along the sliding rod 5112, so that the first rectangular frame 5111 gradually moves away from the second rectangular frame 5121, thereby realizing the control of the position of the lamp bead 2 by the telescopic structure 51.

[0037] Reference Figure 6 As shown: a first pressure spring 5116 is arranged between the first movable seat 5114 and the second movable seat 5115, the first pressure spring 5116 is sleeved on the sliding rod 5112, one end of the first pressure spring 5116 is connected to the first movable seat 5114, and the other end of the first pressure spring 5116 is connected to the second movable seat 5115.

[0038] The third moving seat 5124 and the fourth moving seat 5125 are moved closer to each other under the action of the double-headed screw 5122. When the distance between the third moving seat 5124 and the fourth moving seat 5125 is too close, the distance between the first moving seat 5114 and the second moving seat 5115 is shortened by the action of the first connecting rod 513 and the second connecting rod 514. At this time, the two ends of the first connecting rod 513 are farthest from the middle thereof, and the arm of force for pushing the first moving seat 5114 to move is long, which easily causes the first moving seat 5114 and the second moving seat 5115 to be unable to move away from each other along the sliding rod 5112. A first pressure spring 5116 is arranged, and when the first movable seat 5114 and the second movable seat 5115 approach each other, the first pressure spring 5116 is compressed. The compressed first pressure spring 5116 can provide thrust to the first movable seat 5114 and the second movable seat 5115. At the same time, the first pressure spring 5116 cannot be further compressed after being compressed to a certain extent, so that a certain distance is maintained between the first movable seat 5114 and the second movable seat 5115, thereby facilitating the first connecting rod 513 and the second connecting rod 514 to pull the first movable seat 5114 and the second movable seat 5115 away from each other.

[0039] Reference Figure 5 and Figure 7 As shown: a plurality of telescopic support rods 515 are arranged in a rectangular array between the first rectangular frame 5111 and the second rectangular frame 5121 , one end of the telescopic support rod 515 is connected to the first rectangular frame 5111 , and the other end of the telescopic support rod 515 is connected to the second rectangular frame 5121 .

[0040] One end of the first connecting rod 513 and the second connecting rod 514 is connected to the telescopic platform 511 and the lamp bead 2. This end is subjected to a large downward force. When the lamp bead 2 is retracted into the protective cover 4, although the force arm is shortened, the downward force remains unchanged, which easily causes the first connecting rod 513 and the second connecting rod 514 to bend, resulting in the lamp bead 2 being unable to align with the mounting groove 11 on the mounting plate 1. When the lamp bead 2 is pushed out of the protective cover 4, the lamp bead 2 is also prone to collide with the mounting plate 1. By setting a telescopic support rod 515, a plurality of telescopic support rods 515 connect the first rectangular frame 5111 and the second rectangular frame 5121 When the first rectangular frame 5111 is away from the second rectangular frame 5121, the lengths of several telescopic support columns are extended, and when the first rectangular frame 5111 is close to the second rectangular frame 5121, the lengths of several telescopic support columns are shortened. The telescopic support columns can provide downward supporting force to the first rectangular frame 5111 in both the extended and shortened states, so that the projection of the first rectangular frame 5111 toward the second rectangular frame 5121 can be completely covered on the second rectangular frame 5121, so that the lamp bead 2 can be completely aligned with the mounting groove 11 on the mounting plate 1, avoiding collision between the lamp bead 2 and the mounting plate 1.

[0041] Reference Figure 2 , Figure 4 and Figure 8 As shown: a closing structure 6 is provided at one end of the lampshade 3, and the closing structure 6 includes a first closing plate 61 and a second closing plate 62. The first closing plate 61 and the second closing plate 62 are respectively arranged at the upper and lower ends of the lamp bead 2, and a first rotating shaft 63 is provided on one side of the first closing plate 61. The two ends of the first rotating shaft 63 respectively pass through the protective cover 4 and are axially connected to the protective cover 4. A second rotating shaft 64 is provided on one side of the second closing plate 62. The two ends of the second rotating shaft 64 respectively pass through the protective cover 4 and are axially connected to the protective cover 4. Both sides of the protective cover 4 are provided with a second driving structure 65 for driving the first rotating shaft 63 and the second rotating shaft 64 to rotate.

[0042] When a car collides, the telescopic mechanism 5 retracts the lamp bead 2 into the protective cover 4. The protective cover 4 can protect the lamp bead 2 from multiple directions, but the front end of the protective cover 4 is in an open state, and debris or foreign matter will enter from the front end of the protective cover 4, causing damage to the lamp bead 2. Therefore, a closing structure 6 is provided. When the lamp bead 2 is retracted into the protective cover 4, the second driving structure 65 drives the first rotating shaft 63 and the second rotating shaft 64 to rotate. The first rotating shaft 63 and the second rotating shaft 64 respectively drive the first closing plate 61 and the second closing plate 62 to rotate. The first closing plate 61 and the second closing plate 62 rotate towards each other, so that one side of the first closing plate 61 abuts against one side of the second closing plate 62, and the front end of the protective cover 4 is closed, so that the lamp bead 2 is in a closed space, thereby preventing debris and foreign matter from entering from the front end of the protective cover 4, and protecting the front end of the lamp bead 2.

[0043] Reference Figure 8 and Fig. 9 As shown, the second driving structure 65 includes a first driving arm 651 for driving the first rotating shaft 63 to rotate and a second driving arm 652 for driving the second rotating shaft 64 to rotate. The first driving arm 651 includes a gear 6511, which is connected to the first rotating shaft 63. A rack 6512 is provided on one side of the gear 6511. The rack 6512 is meshed and transmission-connected with the gear 6511. A first guide rod 6514 is provided on one side of the rack 6512. A first slider 6513 is slidably provided on the first guide rod 6514. The first slider 6513 is connected to the rack 6512, a U-shaped frame 6515 is arranged on one side of the first guide rod 6514, the middle part of the U-shaped frame 6515 is connected to the protective cover 4, the two ends of the U-shaped frame 6515 are respectively connected to the two ends of the first guide rod 6514, the second driving arm 652 has the same structure as the first driving arm 651, a linkage structure 653 is arranged between the first driving arm 651 and the second driving arm 652, and the two ends of the linkage structure 653 are respectively connected to the first driving arm 651 and the second driving arm 652.

[0044] During the movement of the lamp bead 2 toward the inside of the protective cover 4, the linkage structure 653 drives the two first sliders 6513 to move along the two first guide rods 6514 respectively, and the two first sliders 6513 drive the two racks 6512 to move horizontally respectively. The movement of the two racks 6512 drives the two gears 6511 to rotate respectively, and the two gears 6511 drive the first rotating shaft 63 and the second rotating shaft 64 to rotate respectively. The first rotating shaft 63 drives the first closing plate 61 to rotate, and the second rotating shaft 64 drives the second closing plate 62 to rotate, thereby simultaneously driving the first closing plate 61 and the second closing plate 62 to move toward each other.

[0045] Reference Fig. 9 and Fig.10 As shown: the linkage structure 653 includes a third rectangular frame 6531, rectangular grooves are provided on both side surfaces of the protective cover 4, the third rectangular frame 6531 is arranged in the rectangular groove, two second guide rods 6532 are arranged in the third rectangular frame 6531, the two second guide rods 6532 are parallel to each other, two ends of the second guide rods 6532 are respectively connected to two ends of the third rectangular frame 6531, second sliders 6533 are slidably provided on the two second guide rods 6532, second pressure springs 6534 are sleeved on the two second guide rods 6532, a first linkage plate 6535 and a second linkage plate 6536 are respectively provided on both sides of the second slider 6533, the middle part of the first linkage plate 6535 is connected to the second slider 6533, the two ends of the first linkage plate 6535 are respectively connected to the first driving arm 651 and the second driving arm 652 through a gear rack structure, one end of the second linkage plate 6536 is connected to the second slider 6533, and the other end of the second linkage plate 6536 is on the moving path of the lamp bead 2.

[0046] When the linkage structure 653 drives the first rotating shaft 63 and the second rotating shaft 64 to move, the linkage structure 653 needs a driving unit to drive it, so that the volume of the vehicle lamp increases. Therefore, the movement of the lamp bead 2 is used as the driving source of the linkage structure 653. During the movement of the lamp bead 2 toward the inside of the protective cover 4, the connecting plate 52 abuts against the two second linkage plates 6536 after moving a certain distance, driving the two second linkage plates 6536 to move. The two second linkage plates 6536 respectively drive the two second sliders 6533 along the second guide rod 65 32 moves, the second pressure spring 6534 is compressed, the two second sliders 6533 respectively drive the two first linkage plates 6535 to move, the first linkage plate 6535 drives the first driving arm 651 and the second driving arm 652 to move, so that the first closing plate 61 and the second closing plate 62 are closed, and when the lamp bead 2 moves toward the outside of the protective cover 4, the second pressure spring 6534 is reset, pushing the second slider 6533 to move along the second guide rod 6532, thereby realizing the contraction of the lamp bead 2 as the driving source of the linkage structure 653.

[0047] Reference Fig.11 As shown: the other end of the second linkage plate 6536 is also provided with a first magnetic block 6537 and a second magnetic block 6538, the first magnetic block 6537 is connected to the other end of the second linkage plate 6536, and the second magnetic block 6538 is connected to the connecting plate 52.

[0048] When the lamp bead 2 moves toward the outside of the protective cover 4, the second pressure spring 6534 is reset, and the second pressure spring 6534 may not be able to completely reset the second slider 6533, so that the first closing plate 61 and the second closing plate 62 cannot be fully opened. The lamp bead 2 is easy to collide with the first closing plate 61 and the second closing plate 62 during the process of continuing to extend. Therefore, a first magnetic block 6537 and a second magnetic block 6538 are provided. When the connecting plate 52 moves to contact with the second linkage plate 6536, the first magnetic block 6537 and the second magnetic block 6538 are The two magnetic blocks 6538 attract each other and fix the connecting plate 52 and the second linkage plate 6536. When the lamp bead 2 moves outward, the connecting plate 52 drives the second linkage plate 6536 to move through the first magnetic block 6537 and the second magnetic block 6538. When the second linkage plate 6536 cannot move, the connecting plate 52 continues to move, and the first magnetic block 6537 separates from the second magnetic block 6538, so that the second slider 6533 can be completely reset, thereby allowing the first closing plate 61 and the second closing plate 62 to be completely reset.

[0049] Reference Fig.10 As shown, a limiting shaft sleeve 6539 is sleeved on the second guide rod 6532 , the limiting shaft sleeve 6539 is arranged at one end of the second guide rod 6532 , and the limiting shaft sleeve 6539 is fixedly connected to the second guide rod 6532 .

[0050] The second slider 6533 moves along the second guide rod 6532 under the action of the first magnetic block 6537 and the second magnetic block 6538. The length of the second guide rod 6532 is relatively long, and the moving distance of the second slider 6533 is relatively far, which makes the rotation angle of the first closing plate 61 and the second closing plate 62 too large. Therefore, a limiting sleeve 6539 is provided. When the second slider 6533 moves to abut against the limiting sleeve 6539, the limiting sleeve 6539 restricts the second slider 6533 from continuing to move. At the same time, under the action of the second pressure spring 6534, the second slider 6533 is pressed against the limiting sleeve 6539, so that the first closing plate 61 and the second closing plate 62 will not continue to move after rotating to a certain angle.

[0051] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
