Description

Technical Field

[0001] This invention relates to the field of vehicle lighting technology, and in particular to a vehicle lighting protection device. Background Technology

[0002] Vehicle lights are tools for illuminating roads when vehicles are driving at night, and also for issuing various vehicle driving signals. Vehicle lights are generally divided into headlights, taillights, turn signals, etc. The type and installation position of vehicle lights may vary depending on the vehicle model, regional regulations and personal preferences, but they all play a vital role in driving safety.

[0003] After being manufactured, car lights are sent to car assembly, repair, modification factories or retail markets, thus requiring transportation. Currently, the most common means of transporting car lights is the collapsible box, which can separate the transported items by inserting panels to ensure transportation safety. However, this method alone cannot provide sufficient protection for car lights and cannot guarantee their safety during transportation.

[0004] A search revealed Chinese invention patent CN110092182B, which discloses a transfer device for automotive headlights. The device includes a support frame comprising a vertically arranged support column and a support frame fixedly installed on top of the support column. A lifting plate is located on the right side inside the support frame. A movable component is located on the side wall of the lifting plate, comprising a lifting assembly and a drive device. The drive device is located at the front end of the lifting plate. An opening is located on the side of the support frame away from the drive device. The lifting assembly is vertically installed on the inner side wall of the support column. A second movable component is located on the lifting plate, and a push plate is fixedly installed on the second movable component. The push plate has a placement groove containing a headlight placement frame. This application facilitates the transport of headlights by placing them in the headlight placement frame with the placement groove and then placing them in a trolley. However, since the headlights themselves are not directly protected during transport, they may detach from the placement groove due to road bumps and vehicle vibrations, compromising the safety of the headlights during transport. Summary of the Invention

[0005] In view of the above-mentioned prior art, the present invention provides a vehicle headlight protection device, the main technical problem to be solved is how to improve the safety of vehicle headlights during transportation.

[0006] To achieve the above objectives, the technical solution of this invention is implemented as follows:

[0007] A vehicle light protection device includes a protective box and a box cover. The protective box is used to load the vehicle light. The interior of the protective box is provided with a support mechanism and a protective mechanism. The support mechanism is used to support and fix the vehicle light, and the protective mechanism is used to wrap the vehicle light.

[0008] The protective mechanism includes an airbag, which consists of a first airbag and a second airbag. The first airbag and the second airbag are located at the top and outer sides of the headlight, respectively. The bottom of the first airbag has several air holes, and a bubble is fixedly connected to the bottom of the first airbag at each air hole. The support mechanism includes several suction cups, which are located at the bottom of the vehicle. The bottom of the suction cups is fixedly connected to a pipe, which includes a folded pipe and a support pipe. Several elastic strips are provided on the outer side of the pipe between the suction cup and the bottom inner wall of the protective box. A negative pressure mechanism is provided on one side of the protective box to provide negative pressure to the suction cups.

[0009] Furthermore, the lid is located at the top of the protective box, and the airbag is fixedly connected to the inner wall of the top of the lid. The first airbag is elliptical cylindrical, and the second airbag is elliptical cylindrical. The second airbag is located at the bottom outer side of the first airbag. Together, they form an inverted bowl-shaped airbag. The airbag is made of nylon, and there are several folds at equal intervals on both the inner and outer sides of the airbag. The material of the airbag is latex.

[0010] Furthermore, a pad is fixedly connected to the inner wall of the bottom of the protective box. The pad is made of sponge and has an opening in the middle. Several first through holes are opened on the inner side of the opening at the bottom of the protective box. The support tube is fixedly connected to the protective box at the first through holes. The folding tube is fixedly connected between the support tube and the suction cup. The elastic strip is made of rubber.

[0011] Furthermore, the outer side of the box cover is provided with several threaded through holes at equal intervals, and the box cover is threadedly connected to the threaded through holes with bolts. The top of both the box cover and the airbag is provided with a second through hole, and the box cover and the airbag are fixedly connected to the same air cylinder at the second through hole. The top of the air cylinder is provided with a one-way valve, the top of the outer side of the air cylinder is provided with a threaded groove, and the top of the air cylinder is threadedly connected to a sealing cap.

[0012] Furthermore, the one-way valve consists of three valves, all of which are inclined downwards. Several protrusions are fixedly connected at equal intervals on the outer side of the top of the sealing cap. The protrusions are arranged in a circle, and the diameter of the circle formed by the protrusions is equal to the diameter of the air cylinder. A pointed cone is fixedly connected at the middle of the top of the sealing cap. The pointed cone is in the shape of a four-sided pyramid. Several elastic ropes are fixedly connected at equal intervals between the outer side of the inner wall of the top of the first bladder and the outer side of the inner wall of the bottom of the second bladder.

[0013] Furthermore, the negative pressure mechanism includes an air chamber, which is fixedly connected to the bottom of one side of the protective box. A third through hole is opened on one side of the top of the air chamber, and a first threaded rod is rotatably connected to the air chamber at the third through hole. A knob is fixedly connected to the top of the first threaded rod. A second threaded rod is rotatably connected to the other side of the inner wall of the top of the air chamber. Both the second threaded rod and the first threaded rod are connected to pulleys by keys at the top of the rod body inside the air chamber. The same belt is sleeved on the outside of the two pulleys.

[0014] Furthermore, both the first and second threaded rods have threaded sleeves threaded to their bottom outer ends. The bottom ends of the two threaded sleeves are fixedly connected to the same push plate, and the outside of the push plate is fixedly connected to a rubber sealing strip. The bottom of the protective box is fixedly connected to a cover outside the pipe. A fourth through hole is opened on one side of the cover and the bottom of the air chamber. The cover and the air chamber are fixedly connected to the same air pipe at the two fourth through holes.

[0015] Furthermore, the protective box is fixedly connected to four legs at the bottom outer corners, and rubber anti-slip pads are fixedly connected to the bottom of each of the four legs.

[0016] Furthermore, sleeves are fixedly connected to the four corners of the top outer side of the box cover. The four sleeves are on the same axis as the four legs. Each sleeve includes a sleeve body and a pad. The pad is connected to the box cover, and the sleeve body is fixedly connected to the top outer side of the pad. The inner diameter of the sleeve body is equal to the diameter of the leg.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. When transporting vehicle lights, they can be placed in a protective box with the lampshade facing down. At this time, the negative pressure mechanism can be operated to allow the suction cups to adhere to the smooth surface of the lampshade. The telescopic tube can also allow different suction cups to be at different heights under the pressure of the vehicle light's weight, thus adapting to the curved surface of the lampshade and achieving initial fixation. Then, an air pump or air cylinder can be used to inflate the airbag to wrap around the vehicle light, thereby protecting it. Continuing to inflate the airbag will also cause it to expand, allowing it to fit against the lamp holder and thus limit the movement of the vehicle light. In this case, the vehicle light will be completely wrapped by flexible material, thus ensuring its safety during transportation.

[0019] 2. After the vehicle lights are transported, the sealing cap can be removed and the cone inserted into the air cylinder after being turned upside down. At this time, the cone can open the one-way valve composed of three valves. At the same time, due to the presence of the protrusion, the sealing cap cannot be completely fitted with the air cylinder. Therefore, the air in the airbag can flow through the gap between the two. As a result, the elastic rope will pull the airbag to contract through its own elasticity. After that, the negative pressure mechanism is operated to release the suction cup to release the vehicle lights. The vehicle lights can then be taken out after the box is opened, thus ensuring the convenience of taking out the vehicle lights after transportation.

[0020] 3. By setting sleeves that are compatible with the support legs, when multiple vehicle lights need to be transported at the same time, a corresponding number of these devices can be used. After loading the vehicle lights, the protective boxes can be stacked. At this time, the upper support legs can be embedded in the lower sleeves to combine and connect several protective boxes, thereby ensuring the stability of the transport boxes during transportation.

[0032] Example 1

[0033] See attached document Figure 1-6 This application provides a vehicle light protection device, including a protective box 1 and a box cover 8. The two can be matched to form a closable box. The protective box 1 is used to load the vehicle light and thus protect it. The protective box 1 is provided with a support mechanism and a protection mechanism inside. The support mechanism is used to support and fix the vehicle light to prevent the vehicle light from shaking too much during transportation. The protection mechanism is used to wrap the vehicle light, thus preventing the vehicle light from being subjected to hard collisions during transportation.

[0034] The protective mechanism includes an airbag 10, which consists of a first bladder 1001 and a second bladder 1002. The first bladder 1001 and the second bladder 1002 are located at the top and outer side of the headlight, respectively. When the airbag 10 is inflated, the two bladders expand at different positions of the headlight to provide comprehensive protection. The bottom of the first bladder 1001 has several air holes, and a bubble 12 is fixedly connected to the bottom of the first bladder 1001 at each air hole. The latex bubble 12 can further expand after the airbag 10 is fully inflated, thus reducing the range of motion of the headlight and providing sufficient protection. The support mechanism includes several suction cups 5 located at the bottom of the vehicle. The suction cups 5 are used to adhere to the headlight cover. Since the surface of the headlight cover is often relatively smooth, the suction cups can be used to... The headlight is fixed in place, and the bottom of the suction cup 5 is fixedly connected to a pipe 4. The pipe 4 includes a folded tube 401 and a support tube 402. The presence of the folded tube 401 allows the pipe 4 to extend and retract. Therefore, after the headlight is placed in the protective box 1, the headlight's own weight will press against the suction cup 5, allowing the suction cup to adapt to the curved surface of the lamp cover and produce a height change. Several elastic strips 3 are provided on the outside of the pipe 4 between the suction cup 5 and the bottom inner wall of the protective box 1. The elastic strips 3 can support the suction cup 5 under the above conditions, so that the suction cup 5 can be tightly attached to the surface of the lamp cover, thereby ensuring the fixing effect of the headlight. A negative pressure mechanism is provided on one side of the protective box 1. The negative pressure mechanism is used to provide negative pressure for the suction cup 5. Therefore, after the suction cup 5 is tightly attached to the lamp cover, the air inside is drawn out by the negative pressure mechanism to make the inside a negative pressure state, which can enhance the fixing effect of the suction cup 5 on the headlight.

[0035] The lid 8 is located at the top of the protective box 1. The airbag 10 is fixedly connected to the inner wall of the top end of the lid 8. Therefore, when the vehicle lamp needs to be taken out, the airbag 10 can be taken out by removing the lid 8. In this case, it is more convenient to take out the vehicle lamp. The first bladder 1001 is ellipsoidal in shape, and the second bladder 1002 is elliptical in shape. The second bladder 1002 is located outside the bottom end of the first bladder 1001. The two together form an inverted bowl-shaped airbag 10. The generally elliptical airbag 10 can adapt to the shape of the vehicle lamp and can completely wrap the vehicle lamp after its own inflation. The airbag 10 is a nylon airbag. The nylon airbag has an upper limit on the inflation volume. Therefore, the existence of the airbag 10 is only to cover the vehicle lamp and reduce its movable range. A number of creases are equally spaced on both the inner and outer sides of the airbag 10. The existence of the creases facilitates the directional contraction of the airbag 10 itself after deflation. Therefore, it can be ensured that the airbag 10 is inside the lid 8 when not inflated. The material of the vesicle 12 is latex. The vesicle 12 made of latex has good elasticity and can expand to a greater extent within the range that its material can withstand. Therefore, it can contact the vehicle lamp through the continuous expansion of the vesicle 12 after the airbag 10. At this time, the vehicle lamp can be limited, and at the same time, the fixing effect of the suction cup 5 on the vehicle lamp can be combined to achieve the function of protecting the vehicle lamp. A cushion block 101 is fixedly connected to the inner wall of the bottom end of the protective box 1. The material of the cushion block 101 is sponge. The existence of the sponge can play a cushioning effect at the inner bottom end of the protective box 1. Therefore, during the transportation of the vehicle lamp, if there is severe shaking or vibration, the cushion block 101 can also play a buffering effect on the vehicle lamp. An opening is provided in the middle of the cushion block 101, that is, the cushion block 101 is in the shape of a "hui" character, and the central part of the cushion block 101 is the space where the suction cup 5 is located. A number of first through holes are provided in the inner side of the opening at the bottom end of the protective box 1. The support tube 402 is fixedly connected to the protective box 1 at the first through holes. The folding tube 401 is fixedly connected between the support tube 402 and the suction cup 5. The folding tube 401 can make the suction cup 5 adapt to the arc surface of the lamp cover through its own contraction. The material of the elastic strip 3 is rubber. The bent elastic strip 3 can support the suction cup 5.

[0036] The outer side of the cover 8 has several threaded through holes at equal intervals, and the cover 8 is threaded with bolts 9 at the threaded through holes. The bolts 9 fix the cover 8 and the protective box 1. The top of the cover 8 and the airbag 10 are both provided with a second through hole, and the cover 8 and the airbag 10 are fixedly connected to the same air cylinder 7 at the second through hole. The top of the air cylinder 7 is provided with a one-way valve 701. When it is necessary to inflate the airbag 10, an air cylinder or air pump can be connected to the outside of the air cylinder 7. The presence of the one-way valve 701 makes the inflation process smoother. The top of the outer side of the air cylinder 7 is provided with a threaded groove, and the top of the air cylinder 7 is threaded with a sealing cap 6. The sealing cap 6 can seal the air cylinder 7, so as to ensure that the airbag 10 will not leak after inflation. The one-way valve 701 consists of three valves, all of which are inclined downwards. The presence of these three valves ensures that airflow can only enter the airbag 10 from top to bottom, and cannot flow out from the airbag from bottom to top. Several protrusions 601 are equidistantly fixed to the outer side of the top of the sealing cover 6. These protrusions 601 are arranged in a circle, and the diameter of the circle formed by the protrusions 601 is equal to the diameter of the air cylinder 7. The protrusions 601 are there so that when air needs to be expelled from the airbag 10, the pointed cone 602 can be inverted and inserted into the air cylinder 7. At this time, the three valves can be opened, and air from the airbag 10 can enter the air cylinder 7. Simultaneously, the spaced protrusions 601 create a gap between the sealing cover 6 and the air cylinder 7, allowing air in the air cylinder 7 to be expelled to the outside of the device. The top center of the sealing cover 6 is fixed... A pointed cone 602 is connected to the air cylinder 7. The pointed cone 602 is in the shape of a four-sided pyramid. The four-sided pyramidal pointed cone 602 cannot be adapted to the three valves. Therefore, no matter what angle the pointed cone 602 is inserted into the air cylinder 7, it can ensure that the three valves can be opened. Several elastic ropes 11 are fixedly connected at equal intervals between the outer side of the top inner wall of the first bladder 1001 and the outer side of the bottom inner wall of the second bladder 1002. When the air cylinder 10 inflates, the elastic ropes 11 will be stretched. At this time, due to the presence of the one-way valve 701, the inside of the air cylinder 10 becomes a sealed space. Therefore, the elasticity of the elastic ropes 11 cannot affect the state of the air cylinder 10. When the pointed cone 602 opens the valve and makes the air cylinder 7 connected to the outside, the elastic ropes 11 can pull the air cylinder 10 to contract inside, thereby assisting the air inside to be discharged and allowing it to return to the contracted and folded state.

[0037] The negative pressure mechanism includes an air chamber 13, which is fixedly connected to the bottom of one side of the protective box 1. A third through hole is opened on one side of the top of the air chamber 13, and a first threaded rod 17 is rotatably connected to the air chamber 13 at the third through hole. A knob 16 is fixedly connected to the top of the first threaded rod 17. A second threaded rod 20 is rotatably connected to the other side of the inner wall of the top of the air chamber 13. Both the second threaded rod 20 and the first threaded rod 17 are connected to pulleys 22 by keys at the top of the rods inside the air chamber 13. The two pulleys 22 are fitted with the same belt 21. Therefore, when the knob 16 is turned, not only will the first threaded rod 17 rotate itself, but the first threaded rod 17 can also drive the second threaded rod 20 to rotate through the belt 21 and the two pulleys 22. The synchronous rotation of the two threaded rods can make the two threaded sleeves 18 rise synchronously. Both the first threaded rod 17 and the second threaded rod 20 are threadedly connected to the bottom of their outer ends with threaded sleeves 18. The bottom ends of the two threaded sleeves 18 are fixedly connected to the same push plate 19. The outer side of the push plate 19 is fixedly connected to a rubber sealing strip. The rise of the two threaded sleeves 18 can pull the push plate 19 up. Therefore, the push plate 19 can draw air from the cover 2 into the air chamber 13 through the air pipe 15, thereby reducing the pressure in the suction cup 5 and making it have a stronger adsorption and fixing effect on the car lights. The bottom end of the protective box 1 is fixedly connected to the cover 2 on the outside of the pipe 4. A fourth through hole is opened on one side of the cover 2 and the bottom end of the air chamber 13. The cover 2 and the air chamber 13 are fixedly connected to the same air pipe 15 at the two fourth through holes.

[0038] The protective box 1 has four fixed feet 14 at the bottom outer corners. The length of the feet 14 is greater than the thickness of the cover 2. Therefore, when the feet 14 support the protective box 1, the cover 2 will not touch the ground. The bottom of each of the four feet 14 is fixedly connected with a rubber anti-slip pad.

[0039] Working principle: When transporting vehicle lights, the vehicle lights can be placed in the protective box 1 with the lamp cover facing down until they come into contact with the suction cup 5. At this time, the weight of the vehicle lights will press the suction cup 5, causing the folded tubes 401 at different locations to be compressed to different lengths. At the same time, the elastic strip 3 will bend to resist the above-mentioned gravity, so that the suction cup 5 can adapt to the curved surface of the lamp cover and fit it tightly.

[0040] Then, the knob 16 can be turned, which can drive the first threaded rod 17 to rotate. The first threaded rod 17 can drive the second threaded rod 20 to rotate through the belt 21 and two pulleys 22. The simultaneous rotation of the first threaded rod 17 and the second threaded rod 20 can cause the push plate 19 to move vertically through the two threaded sleeves 18. Thus, the push plate 19 can be adjusted to rise to draw air from the cover 2 into the air chamber 13. At this time, the pressure in the cover 2 decreases, so the suction cup 5 can fix the lamp cover with a smooth surface, thereby achieving the effect of fixing the car lamp.

[0041] Afterwards, the lid 8 can be placed on the protective box 1 and the two can be fixed by tightening the bolts 9. After removing the sealing cover 6, use an air pump or air cylinder to inflate the airbag 10 from the air cylinder 7. During the inflation process, the first bladder 1001 and the second bladder 1002 will gradually expand until they are fully expanded and will cover the headlight. At this time, it is necessary to continue to inflate the airbag 10 so that several bladders 12 can expand. The expanded bladders 12 can fit against the surface of the headlight, thus limiting the headlight. In this case, the headlight will be completely wrapped by the flexible material, thus ensuring its safety during transportation.

[0042] After the vehicle lights are transported using the protective box 1, the sealing cover 6 can be removed, turned upside down, and inserted into the air cylinder 7. At this time, the cone 602 can open the one-way valve 701 composed of three valves. Meanwhile, the presence of the protrusion 601 will prevent the sealing cover 6 and the air cylinder 7 from fitting completely together, leaving a gap between two adjacent protrusions 601. Therefore, when the elastic rope 11 pulls the airbag 10 to contract through its own elasticity, the air inside will be discharged from the air cylinder 7, causing the airbag 10 to return to the folded and contracted state.

[0043] Next, turn the knob 16 in the opposite direction to lower the push plate 19, so that the air pressure in the suction cup 5 can be restored to normal. At this time, the suction cup 5 can release the headlight. Finally, after loosening the bolt 9, open the cover 8 to take out the headlight.

[0044] Example 2

[0045] See attached document Figure 7 This application provides a vehicle headlight protection device. Compared with embodiment 1, in order to facilitate the stacking of multiple devices, sleeves 23 are fixedly connected to the four corners of the top outer side of the box cover 8. The four sleeves 23 are respectively on the same axis as the four support legs 14. The sleeve 23 includes a cylindrical body 2301 and a pad 2302. The pad 2302 is connected to the box cover 8. The pad 2302 is used to raise the protective box 1, thereby preventing the cover 2 from hitting the cone 602 when multiple protective boxes 1 are stacked. The cylindrical body 2301 is fixedly connected to the top outer side of the pad 2302, and the inner diameter of the cylindrical body 2301 is equal to the diameter of the support leg 14. Therefore, the stability of stacking can be achieved by limiting the support leg 14 through the cylindrical body 2301.

[0046] Working principle: When transporting vehicle lights after loading them into the protective box 1, if there are multiple vehicle lights to be transported, multiple protective boxes 1 can be used to load several vehicle lights respectively. Then, during transportation, the protective boxes 1 can be stacked up. At this time, the upper support leg 14 can be embedded into the lower sleeve 23, thereby ensuring the connection effect between the two and ensuring the stability of the protective box 1 during transportation.

[0047] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
