Description

Technical Field

[0001] This utility model relates to the field of automotive hinge technology, and more specifically, to an automotive flip hinge. Background Technology

[0002] A car hinge is a specially designed mechanical connection device, primarily used for the hood (front hatch) or tailgate (rear hatch) of a car, allowing the hood to automatically flip or quickly open / remove when opened. It is commonly found in racing cars, high-performance sports cars, special vehicles with high maintenance accessibility requirements, or modified vehicles.

[0003] Hinges can be made of movable components or foldable materials. However, existing hinges have a certain amount of sliding friction between them when they move, resulting in low wear resistance. Furthermore, existing automotive flip hinges do not have a stop block to limit the hinge block during the flipping process, which can cause the hinge block to impact the hinge seat and potentially damage the door. Utility Model Content

[0004] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides an automotive flip hinge to solve the technical problem mentioned in the background art, where existing hinges have a certain amount of sliding friction inside the hinge during movement, resulting in low wear resistance.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A car flip hinge includes a connecting post, with two sets of first connecting blocks fitted on the upper and lower sides of the connecting post. A first plate is provided at the left end of the two sets of first connecting blocks. A second connecting block is fitted in the middle of the connecting post, and a second plate is provided at the right end of the second connecting block. Multiple sets of annular track grooves are provided at the outer end of the connecting post. Multiple sets of rollers are arranged in annular arrangement at the inner ends of the two sets of first connecting blocks and the second connecting blocks. The multiple sets of rollers slide in the multiple sets of corresponding annular track grooves.

[0006] The present invention is further configured such that an inclined plate is inclinedly provided on the right side of the front end of the second plate, and a locking plate is provided on the upper and lower sides of the front end of the inclined plate. Both sets of locking plates are provided with locking slots. Two sets of elastic locking blocks are inclinedly provided on the left side of the front end of the first plate. The two sets of elastic locking blocks cooperate with the two sets of locking slots in the two sets of locking plates. The outer ends of the two sets of elastic locking blocks are provided with inward arcs. The first plate and the second plate move and flip on the connecting column under the action of the two sets of first connecting blocks and second connecting blocks. The first plate and the second plate are triangular. When the first plate and the second plate are close to closing, the two sets of elastic locking blocks enter the two sets of locking slots in the two sets of locking plates. The two sets of locking plates and the two sets of elastic locking blocks alleviate the impact force of the first plate and the second plate during the locking process, avoid direct impact between the first plate and the second plate, and reduce noise and structural damage.

[0007] The present invention is further configured such that an oil storage chamber is provided inside the connecting column, and lubricating oil is provided in the oil storage chamber. The connecting column is arranged in a ring and connected to multiple sets of oil guiding channels. The multiple sets of oil guiding channels are respectively connected to multiple sets of annular track grooves. Each set of oil guiding channels is provided with an oil suction core. The outer ends of the multiple sets of oil suction cores are connected to mounting plates. The outer ends of the multiple sets of mounting plates are connected to sponge blocks. The multiple sets of oil suction cores are connected to the multiple sets of sponge blocks. The oil storage chamber inside the connecting column stores lubricating oil. The multiple sets of oil suction cores draw lubricating oil from the oil storage chamber and guide it into the sponge blocks on the multiple sets of mounting plates. When the multiple sets of rollers roll in the multiple sets of annular track grooves of the connecting column, the lubricating oil on the multiple sets of sponge blocks lubricates the multiple sets of rollers. This can replenish lubricating oil in a timely manner, reduce the number of times lubricating oil needs to be added manually, and save time and effort.

[0008] The present invention is further configured such that a fixing ring is fixedly provided on the inner side of each of the multiple sets of oil guiding channels of the connecting column, and a spring is provided on each of the multiple sets of fixing rings. The multiple sets of springs are respectively connected to the multiple sets of mounting plates and are respectively located on the outer side of the multiple sets of oil suction cores. Under the action of the multiple sets of springs, the sponge blocks on the multiple sets of mounting plates are driven to slightly extend to the outer side of the multiple sets of oil guiding channels of the connecting column. The multiple sets of rollers will contact the multiple sets of sponge blocks when they roll, thereby ensuring the lubrication effect on the rollers.

[0009] The present invention is further configured such that the top of the oil storage chamber of the connecting column is provided with an opening, the inner side of the opening is provided with a thread, and an installation cover is provided at the opening. Multiple sets of installation covers are provided with multiple sets of protrusions on the upper side of their outer ends. By providing the installation cover, when the lubricating oil in the oil storage chamber of the connecting column is used up, the installation cover is unscrewed on the connecting column, and then the lubricating oil is added to the oil storage chamber of the connecting column. Then the installation cover is threaded onto the opening of the connecting column, which facilitates the replenishment of lubricating oil in the oil storage chamber of the connecting column.

[0010] The present invention is further configured such that multiple sets of auxiliary wheels are provided at the top and bottom of the second connecting block, and annular grooves are provided at the inner ends of the two sets of first connecting blocks. The multiple sets of auxiliary wheels roll in the two sets of annular grooves respectively. By setting the auxiliary wheels, when the first plate and the second plate drive the two sets of first connecting blocks and the second connecting block to rotate around the connecting column, the multiple sets of auxiliary wheels on the second connecting block roll in the annular grooves of the two sets of first connecting blocks, which can reduce the friction between the two sets of first connecting blocks and the second connecting block, and ensure that the two sets of first connecting blocks and the second connecting block are at the same center point.

[0011] The present invention is further configured such that a silicone buffer block is provided in the slot of each of the two sets of card plates. By providing the silicone buffer block, the two sets of elastic card blocks and the two sets of card plates can undergo elastic deformation during the carding process, thereby absorbing kinetic energy and improving their buffering effect.

[0019] Please see Figure 1-7 A car flip hinge includes a connecting post 1, with two sets of first connecting blocks 2 fitted on the upper and lower sides of the connecting post 1. A first plate 3 is provided at the left end of the two sets of first connecting blocks 2. A second connecting block 4 is fitted in the middle of the connecting post 1. A second plate 5 is provided at the right end of the second connecting block 4. Multiple sets of annular track grooves are provided at the outer end of the connecting post 1. Multiple sets of rollers 6 are arranged in annular arrangement at the inner ends of the two sets of first connecting blocks 2 and second connecting blocks 4. The multiple sets of rollers 6 slide in the multiple sets of corresponding annular track grooves.

[0020] In this embodiment, the first plate 3 and the second plate 5 are respectively installed at designated positions on the car. When the car hood is opened, the two sets of first connecting blocks 2 and second connecting blocks 4 rotate around the connecting post 1, and multiple sets of rollers 6 roll in multiple sets of annular track grooves of the connecting post 1. This can reduce the frictional force of rotation between the connecting post 1, the first connecting block 2 and the second connecting block 4, and enhance its wear resistance.

[0021] Please see Figure 1 , Figure 2 and Figure 7 As one embodiment of the first plate 3 and the second plate 5, in this utility model, the second plate 5 is provided with an inclined plate 7 on the right side of its front end. The upper and lower sides of the front end of the inclined plate 7 are provided with a locking plate 8. Both sets of locking plates 8 are provided with a locking groove. The first plate 3 is provided with two sets of elastic locking blocks 9 on the left side of its front end. The two sets of elastic locking blocks 9 are engaged with the two sets of locking grooves in the two sets of locking plates 8. The outer ends of the two sets of elastic locking blocks 9 are provided with an inward arc.

[0022] Specifically, the first plate 3 and the second plate 5 move and flip on the connecting column 1 under the action of the two sets of first connecting blocks 2 and second connecting blocks 4, and the first plate 3 and the second plate 5 are triangular. When the first plate 3 and the second plate 5 are close to closing, the two sets of elastic locking blocks 9 enter the two sets of locking slots of the two sets of locking plates 8. The two sets of locking plates 8 and the two sets of elastic locking blocks 9 alleviate the impact force of the first plate 3 and the second plate 5 during the locking process, avoid direct impact between the first plate 3 and the second plate 5, and reduce noise and structural damage.

[0023] Please see Figures 1-6As one embodiment of the connecting column 1, the connecting column 1 in this utility model is provided with an oil storage chamber inside, the oil storage chamber is provided with lubricating oil, and the connecting column 1 is provided with multiple sets of oil guiding channels in a ring arrangement. The multiple sets of oil guiding channels are respectively connected to multiple sets of annular track grooves. Each set of oil guiding channels is provided with an oil suction core 10. The outer ends of the multiple sets of oil suction cores 10 are connected to mounting plates 11, and the outer ends of the multiple sets of mounting plates 11 are connected to sponge blocks 12. The multiple sets of oil suction cores 10 and the multiple sets of... The sponge block 12 is connected, and a fixing ring 13 is fixedly provided on the inner side of the multiple sets of oil guiding channels of the connecting column 1. A spring 14 is provided on each of the multiple sets of fixing rings 13. The multiple sets of springs 14 are respectively connected to the multiple sets of mounting plates 11. The multiple sets of springs 14 are respectively located on the outer side of the multiple sets of oil suction cores 10. An opening is provided at the top of the oil storage chamber of the connecting column 1. A thread is provided on the inner side of the opening. An installation cover 15 is threaded at the opening. Multiple sets of protrusions are provided on the upper side of the outer end of the multiple sets of installation covers 15.

[0024] Specifically, the oil reservoir in the connecting column 1 stores lubricating oil. Multiple sets of oil suction cores 10 draw the lubricating oil from the reservoir and guide it into the sponge blocks 12 on the mounting plates 11. When the multiple sets of rollers 6 roll in the multiple sets of annular track grooves of the connecting column 1, the lubricating oil on the sponge blocks 12 lubricates the rollers 6, allowing for timely replenishment of lubricating oil and reducing the number of times lubricating oil needs to be added manually, saving time and effort. Under the action of multiple sets of springs 14, the sponge blocks 12 on the mounting plates 11 extend slightly to the outside of the multiple sets of oil guide channels of the connecting column 1. The rolling of the multiple sets of rollers 6 will contact the sponge blocks 12, thus ensuring the lubrication effect on the rollers 6. By setting the mounting cover 15, when the lubricating oil in the oil reservoir of the connecting column 1 is used up, the mounting cover 15 is unscrewed from the connecting column 1, and then lubricating oil is added to the oil reservoir of the connecting column 1. Then, the mounting cover 15 is threaded onto the opening of the connecting column 1, making it convenient to replenish the lubricating oil in the oil reservoir of the connecting column 1.

[0025] Please refer to Figure 3 and Figure 4 As a further embodiment of the first connecting block 2 and the second connecting block 4: the top and bottom ends of the second connecting block 4 are provided with multiple sets of auxiliary wheels 16, and the inner ends of the two sets of the first connecting blocks 2 are provided with annular grooves, and the multiple sets of auxiliary wheels 16 roll in the two sets of annular grooves respectively.

[0026] Specifically, by setting auxiliary wheels 16, when the first plate 3 and the second plate 5 drive the two sets of first connecting blocks 2 and second connecting blocks 4 to rotate around the connecting column 1, the multiple sets of auxiliary wheels 16 on the second connecting block 4 roll in the annular grooves of the two sets of first connecting blocks 2, which can reduce the friction between the two sets of first connecting blocks 2 and the second connecting blocks 4, and ensure that the two sets of first connecting blocks 2 and the second connecting blocks 4 are at the same center point.

[0027] In this invention, silicone buffer blocks 17 are provided in the slots of both sets of card plates 8. By providing silicone buffer blocks 17, the two sets of elastic blocks 9 and the two sets of card plates 8 can undergo elastic deformation during the carding process, thereby absorbing kinetic energy and improving their buffering effect.

[0028] In summary, when using the overall equipment: The first plate 3 and the second plate 5 are respectively installed in designated positions on the car. When the car hood is opened, the two sets of first connecting blocks 2 and second connecting blocks 4 rotate around the connecting post 1. The multiple sets of auxiliary wheels 16 on the second connecting block 4 roll in the annular grooves of the two sets of first connecting blocks 2, and the multiple sets of rollers 6 roll in the multiple annular track grooves of the connecting post 1, thereby reducing the frictional force of rotation between the connecting post 1, the first connecting block 2 and the second connecting block 4.

[0029] The first plate 3 and the second plate 5 move and flip on the connecting post 1 under the action of the two sets of first connecting blocks 2 and second connecting blocks 4. The first plate 3 and the second plate 5 are triangular. When the first plate 3 and the second plate 5 are close to closing, the two sets of elastic locking blocks 9 enter the two sets of locking slots of the two sets of locking plates 8. Through the action of the two sets of silicone buffer blocks 17, the two sets of locking plates 8 and the two sets of elastic locking blocks 9 buffer the impact force of the first plate 3 and the second plate 5 during the locking process.

[0030] The oil storage chamber inside the connecting column 1 stores lubricating oil. Multiple sets of oil suction cores 10 draw the lubricating oil from the oil storage chamber and guide it into the sponge blocks 12 on the multiple sets of mounting plates 11. When the multiple sets of rollers 6 roll in the multiple sets of annular track grooves of the connecting column 1, the lubricating oil on the multiple sets of sponge blocks 12 lubricates the multiple sets of rollers 6.

[0031] When the lubricating oil in the oil reservoir of the connecting column 1 is used up, unscrew the mounting cap 15 onto the connecting column 1, then replenish the lubricating oil into the oil reservoir of the connecting column 1, and then thread the mounting cap 15 onto the opening of the connecting column 1.
