Description

Technical Field

[0001] This invention relates to the field of vehicle parts technology, and in particular to an electric adjustment mechanism for the attitude of a racing roll cage adapted to ergonomics. Background Technology

[0002] A racing roll cage is a metal frame structure installed inside the cockpit of a racing car. It is usually made of high-strength steel tubing and is one of the most important passive safety devices for racing cars. Its main function is to enhance the rigidity of the car body, prevent the cockpit from being crushed in the event of a rollover, and also to disperse the impact force generated during a vehicle collision.

[0003] In the current technology, in order to ensure protection for the driver's side, racing roll cages usually have one or two diagonal support bars installed on the inside of the door. When the door is hit, the diagonal support bars can block the deformed door from the inside of the door, preventing it from deforming excessively.

[0004] However, the presence of the diagonal support bar also makes it difficult for the driver to get in and out of the car. Although the diagonal support bar on some race car roll cages can be adjusted to allow the driver to avoid obstacles when getting in and out of the car, the actual adjustment process is often quite cumbersome.

[0005] Therefore, it is necessary to invent an electric adjustment mechanism for the attitude of a racing roll cage that is adapted to ergonomics to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an electric adjustment mechanism for the attitude of a racing roll cage that is adapted to ergonomics. It facilitates driver entry and exit while ensuring support strength, is easy to operate, and is more ergonomic, ensuring safety and comfort. This solves the problem mentioned in the background art that the presence of the diagonal support rod makes it difficult for the driver to easily get in and out of the car. Although the diagonal support rod on some racing roll cages can be adjusted to avoid obstacles when the driver gets in and out of the car, the actual adjustment process is often quite cumbersome.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electric adjustment mechanism for the attitude of a racing roll cage adapted to ergonomics, comprising a roll cage assembly, a front reinforcement assembly provided on the front side of the roll cage assembly, a rear reinforcement assembly provided on the rear side of the roll cage assembly, side blocking assemblies A provided on the front of both sides of the roll cage assembly, a driven adjustment assembly provided on the rear side of any set of side blocking assemblies A, and two sets of side blocking assemblies B provided on the rear side of the driven adjustment assembly; Each set of side blocking components B includes a side stop bar B fixedly disposed through the rear side of an adjacent rotating housing. The rear end of the outer surface of the side stop bar B is provided with a guide groove. The inner side of the side stop bar B is slidably disposed with a locking rod adapted to a locking hole and whose rear end is inserted into the inner side of an adjacent locking hole via a linear bearing. The front end of the locking rod is fixedly connected to a drive column slidably disposed within an annular groove. The rear end of the locking rod is fixedly disposed through a guide column slidably disposed within the guide groove. The outer side of the side stop bar B is slidably sleeved with a reinforcing sleeve fixedly sleeved outside the guide column via a linear bearing. The rear end of the reinforcing sleeve is provided with a locking groove adapted to an inverted U-shaped frame. The reinforcing sleeve is sleeved on the outer side of the inverted U-shaped frame through the locking groove.

[0008] Preferably, the roll cage assembly includes an inverted U-shaped frame, with L-shaped frames fixedly connected to both sides of the front end of the inverted U-shaped frame, a crossbar fixedly connected between the two L-shaped frames, and diagonal frames fixedly connected to both sides of the rear end of the inverted U-shaped frame.

[0009] Preferably, the bottom ends of the fixed plate, the bottom ends of the two L-shaped frames, and the bottom ends of the two inclined frames are all fixedly connected to fixed plates, and mounting holes are provided at the four corners of the top of any fixed plate.

[0010] Preferably, the front reinforcement assembly includes a front reinforcement rod fixedly connected between two L-shaped frames, and reinforcement diagonal braces are fixedly connected to both sides of the bottom of the front reinforcement rod, with each reinforcement diagonal brace being fixedly connected to the adjacent L-shaped frame.

[0011] Preferably, the rear reinforcement assembly includes an X-shaped reinforcement frame and a rear reinforcement rod distributed in the vertical direction, and both the X-shaped reinforcement frame and the rear reinforcement rod are fixedly installed inside the inverted U-shaped frame.

[0012] Preferably, any group of the side blocking components A includes two side stops A fixedly connected to the adjacent L-shaped frame, and the rear ends of the two side stops A are fixedly connected to an arc plate, the outer surface of which has a limit groove.

[0013] Preferably, an inner plate is fixedly provided on the inner side of the arc-shaped plate, and a shielding shell is fixedly installed on the inner side of the inner plate. A worm gear is rotatably nested inside the shielding shell via a ball bearing. A motor is fixedly provided at the bottom of the shielding shell, and the motor is connected to the worm gear drive.

[0014] Preferably, a switch is installed on the top of the shield housing, and the motor is electrically connected to the racing car battery through the switch.

[0015] Preferably, any set of the driven adjustment components includes a rotating shaft rotatably mounted on the inner side of the inner plate via a ball bearing. A worm wheel that meshes with an adjacent worm gear is fixedly sleeved on the inner end of the outer side of the rotating shaft.

[0016] The technical effects and advantages of this invention are as follows:

[0017] This invention incorporates a driven adjustment component and two sets of side blocking components B. When the driver gets in or out of the vehicle, the driven adjustment component A can be driven by the side blocking components A, thereby releasing the double lock of the two sets of side blocking components B. The driven adjustment component then rotates the two sets of side blocking components B to avoid obstruction. Conversely, when the side blocking components B are needed to provide lateral obstruction, the driven adjustment component A can be driven to move the two sets of side blocking components B to the blocking position, whereby the two sets of side blocking components B double-lock the roll cage assembly. This design facilitates driver entry and exit while maintaining support strength, offering convenient operation, improved ergonomics, and ensuring both safety and comfort.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides, for example Figures 1-6 The electric adjustment mechanism for the attitude of a racing roll cage, adapted to ergonomics, includes a roll cage assembly 1, a front reinforcement assembly 2 on the front side of the roll cage assembly 1, a rear reinforcement assembly 3 on the rear side of the roll cage assembly 1, side blocking assemblies A4 on both front sides of the roll cage assembly 1, a driven adjustment assembly 5 on the rear side of any set of side blocking assemblies A4, and two sets of side blocking assemblies B6 on the rear side of the driven adjustment assembly 5.

[0022] like Figure 2 As shown, the roll cage assembly 1 includes an inverted U-shaped frame 11, with L-shaped frames 12 fixedly connected to both sides of the front end of the inverted U-shaped frame 11, and a crossbar 13 fixedly connected between the two L-shaped frames 12. Diagonal frames 14 are fixedly connected to both sides of the rear end of the inverted U-shaped frame 11. All four components are made of 4130 chromium-molybdenum alloy steel pipe, which has high tensile strength and strong impact toughness, and is not easy to break during rollover / collision. Fixed plates 15 are fixedly connected to both ends of the bottom of the fixed plate 15, the bottom ends of the two L-shaped frames 12, and the bottom ends of the two diagonal frames 14. The fixed plate 15 is made of Q355B low alloy high-strength steel, which has high strength and can be stably connected to the vehicle body. Mounting holes are opened at the four corners of the top of any fixed plate 15.

[0023] The above structure is designed to facilitate the installation and fixation of the roll cage assembly 1 inside the race car using the mounting holes.

[0024] like Figure 3As shown, the front reinforcement component 2 includes a front reinforcement rod 21 fixedly connected between two L-shaped frames 12. Both sides of the bottom of the front reinforcement rod 21 are fixedly connected with reinforcement diagonal rods 22, both of which are made of 4130 chromium-molybdenum alloy steel pipes. Any one of the reinforcement diagonal rods 22 is fixedly connected to the adjacent L-shaped frame 12.

[0025] By setting up the above structure, it is possible to reinforce the two L-shaped frames 12 by using the front reinforcing rod 21 and the two reinforcing diagonal rods 22.

[0026] like Figure 3 As shown, the rear reinforcement component 3 includes an X-shaped reinforcement frame 31 and a rear reinforcement rod 32 distributed in the vertical direction, which are also made of 4130 chromium-molybdenum alloy steel pipe. The X-shaped reinforcement frame 31 and the rear reinforcement rod 32 are both fixedly installed inside the inverted U-shaped frame 11.

[0027] By setting up the above structure, it is possible to reinforce the inverted U-shaped frame 11 using the X-shaped reinforcing frame 31 and the rear reinforcing rod 32.

[0028] like Figure 4 As shown, any set of side blocking components A4 includes two side blocks A41 fixedly connected to the adjacent L-shaped frame 12. The rear ends of the two side blocks A41 are fixedly connected to an arc plate 42. A limit groove 43 is opened on the outer surface of the arc plate 42. An inner plate 44 is fixedly installed on the inner side of the arc plate 42. A shielding housing 45 is fixedly installed on the inner side of the inner plate 44. A worm gear 46 is rotatably nested inside the shielding housing 45 through a ball bearing. A motor 47 is fixedly installed at the bottom of the shielding housing 45. The motor 47 is connected to the worm gear 46 through a transmission. A switch is installed on the top of the shielding housing 45. The motor 47 is electrically connected to the racing car battery through the switch.

[0029] By setting up the above structure, when the driver in the racing seat needs to get out of the car or the driver on the side of the door needs to get in, the motor 47 is started by a switch. After the motor 47 is started, it drives the worm gear 46 to rotate, and the worm gear 46 drives the worm wheel 52 to rotate.

[0030] like Figure 5 As shown, any set of driven adjustment components 5 includes a rotating shaft 51 rotatably mounted on the inner side of the inner plate 44 via a ball bearing. A worm wheel 52 that meshes with the adjacent worm 46 is fixedly sleeved on the inner end of the outer side of the rotating shaft 51. An eccentric wheel 53 and a rotating housing 54 are sequentially sleeved on the outer side of the rotating shaft 51 from the inside to the outside. The eccentric wheel 53 is fixedly connected to the rotating shaft 51. The rotating housing 54 is rotatably connected to the rotating shaft 51 via a ball bearing. A torsion spring 55 in an energy storage state is fixedly connected between the outer wall of the eccentric wheel 53 and the inner wall of the rotating housing 54. An annular groove 56 is opened on the inner side of the eccentric wheel 53. A limiting post 57 that is slidably mounted on the inner side of the adjacent limiting groove 43 is fixedly mounted on the top of the rotating housing 54.

[0031] By setting up the above structure, when the worm gear 46 drives the worm wheel 52 to rotate, the worm wheel 52 drives the eccentric wheel 53 to rotate clockwise through the rotating shaft 51. When the eccentric wheel 53 rotates, it pulls the two drive columns 64 through the annular groove 56, and at the same time releases the energy stored in the torsion spring 55. After the torsion spring 55 has released its energy, the annular groove 56, which continues to rotate, drives the rotating housing 54 to rotate synchronously through the torsion spring 55. When the rotating housing 54 rotates, it drives the two sets of side blocking components B6 to rotate counterclockwise, thereby releasing the obstruction to the racing seat.

[0032] like Figure 6 As shown, any set of side blocking components B6 includes a side stop bar B61 fixedly disposed through the rear side of the adjacent rotating housing 54. The rear end of the outer surface of the side stop bar B61 is provided with a guide groove 62. The inner side of the side stop bar B61 is slidably disposed with a locking rod 63 adapted to the locking hole 16 and inserted into the inner side of the adjacent locking hole 16 via a linear bearing. The front end of the locking rod 63 is fixedly connected to a drive column 64 slidably disposed inside the annular groove 56. The rear end of the locking rod 63 is fixedly disposed through a guide column 65 slidably disposed inside the guide groove 62. The outer side of the side stop bar B61 is slidably sleeved with a reinforcing sleeve 66 fixedly sleeved outside the guide column 65 via a linear bearing. The rear end of the reinforcing sleeve 66 is provided with a locking groove 67 adapted to the inverted U-shaped frame 11. The reinforcing sleeve 66 is sleeved on the outer side of the inverted U-shaped frame 11 through the locking groove 67.

[0033] By setting up the above structure, when the eccentric wheel 53 rotates, it can pull the two drive columns 64 through the annular groove 56. The two drive columns 64 will then pull the two locking rods 63 forward inside the two side stops B61. At this time, the rear ends of the two locking rods 63 will move out from the inside of the two adjacent locking holes 16, thereby releasing the first lock. During the movement of the locking rods 63, the guide rods 65 located inside the guide groove 62 will drive the adjacent reinforcing sleeves 66 to move synchronously, thereby causing the reinforcing sleeves 66 to move the locking groove 67 forward, thereby causing the reinforcing sleeves 66 to disengage from the outside of the inverted U-shaped frame 11, thereby releasing the second lock. After the two locking rods 63 move out, the torsion spring 55 will release its energy. At this time, the annular groove 56, which continues to rotate, will drive the rotating housing 54 to rotate synchronously through the torsion spring 55. When the rotating housing 54 rotates, it will drive the two sets of side blocking components B6 to rotate counterclockwise through the two side stops B61, thereby releasing the obstruction to the side of the racing seat.

[0034] The specific working process of this invention is as follows: like Figure 1 As shown, at this time, the driver sitting in the racing seat is blocked by the two sets of side blocking components B6 adjacent to it. When the driver in the racing seat needs to get out of the car or the driver on the side of the door needs to get in, the motor 47 is started by the switch. After the motor 47 starts, it drives the worm 46 to rotate, which in turn drives the worm wheel 52 to rotate. The rotation of the worm wheel 52, in turn, drives the eccentric wheel 53 to rotate clockwise via the rotating shaft 51. Figure 5 (Based on the reference), when the eccentric wheel 53 rotates, it pulls the two drive columns 64 through the annular groove 56, and at the same time releases the energy of the torsion spring 55 which is in the energy storage state. The two drive columns 64 then pull the two locking rods 63 forward on the inside of the two side stops B61 respectively. At this time, the rear ends of the two locking rods 63 are moved out from the inside of the two adjacent locking holes 16 respectively. During the movement of the locking rods 63, the guide slide column 65 located inside the guide slide groove 62 drives the adjacent reinforcing sleeve 66 to move synchronously, thereby causing the reinforcing sleeve 66 to drive the locking groove 67 to move forward, thereby causing the reinforcing sleeve 66 to disengage from the outside of the inverted U-shaped frame 11. After the two locking levers 63 are removed, the torsion spring 55 releases its energy. At this time, the annular groove 56 continues to rotate, which drives the rotating housing 54 to rotate synchronously through the torsion spring 55. When the rotating housing 54 rotates, it drives the two sets of side blocking components B6 to rotate counterclockwise through the two side stops B61, thereby releasing the obstruction on the side of the racing seat. During the rotation of the rotating housing 54, the limiting post 57 rotates synchronously. When the limiting post 57 rotates, it moves out synchronously inside the limiting groove 43. When the limiting groove 43 reaches the bottom of the inner side of the arc plate 42, the motor 47 is stopped by the switch. At this time, the driver can get off or get on the vehicle. When the driver gets into the vehicle and requires the two sets of side blocking assemblies B6 to provide side blocking, the motor 47 is started again via the switch, and the driving direction of the motor 47 is changed. At this time, the rotating shaft 51 drives the eccentric wheel 53 to rotate counterclockwise (towards...). Figure 5 (Based on the reference), during this process, the eccentric wheel 53 drives the rotating housing 54 to rotate counterclockwise through the torsion spring 55, and the rotating housing 54 drives the two sets of side blocking components B6 to rotate counterclockwise synchronously until the limiting post 57 moves from the bottom end of the inner side of the limiting groove 43 to the top end of the inner side of the limiting groove 43. At this time, the two locking rods 63 are aligned with the two locking holes 16 respectively. Due to the obstruction of the limiting groove 43, the rotating housing 54 cannot continue to rotate. Subsequently, as the eccentric wheel 53 continues to rotate, the torsion spring 55 is charged with energy. At the same time, the eccentric wheel 53 pushes the two drive columns 64 through the annular groove 56, thereby causing the drive columns 64 to drive the locking rod 63 to slide backward inside the side stop bar B61 until the rear end of the locking rod 63 is inserted into the inner side of the adjacent locking hole 16 to form the first lock. Then, the motor 47 is stopped by the switch. During the backward movement of the locking rod 63, the reinforcing sleeve 66 moves backward synchronously through the guide slide 65. When the rear end of the locking rod 63 is inserted into the inner side of the adjacent locking hole 16, the reinforcing sleeve 66 simultaneously passes through the locking groove 67 and engages with the outer side of the inverted U-shaped frame 11, thereby forming a second locking. Subsequently, when the door is subjected to pressure by the side blocking assembly A4, the driven adjustment assembly 5 and the outer side of the two sets of side blocking assemblies B6 due to a collision, the double locking support strength is higher.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
