Description

Technical Field

[0001] The invention belongs to the technical field of vehicle devices, in particular to a multi-axis suspension axle assembly. Background Art

[0002] The axle is a shaft that transmits power between the main reducer (differential) and the drive wheels. It is mostly solid, with its inner end connected to the half-axle gear of the differential and the outer end connected to the drive wheel hub. The function of the axle is to transmit the forces in all directions between the frame or load-bearing body and the wheels and the bending moment and torque generated by them.

[0003] As people's living standards continue to improve, toy cars are no longer limited to simply imitating the appearance of real vehicles but unable to drive automatically. The age range of toy car players is also gradually expanding, and the experience required for simulated vehicles is also increasing. As a result, most existing simulated vehicles, such as simulated trailers, not only drive on flat roads, but also drive on complex roads such as in the wild and muddy areas to imitate the functions of real trailers. However, the size and height of simulated trailers are much lower than real trailers after all. When encountering speed bumps on the road or earth slopes in the wild, they cannot drive smoothly like real trailers relying on their own height and power. Therefore, the axle at the bottom of the simulated trailer is very likely to be stuck or worn by roadblocks, which greatly reduces the service life and cost of the simulated trailer.

[0004] In view of this, in order to overcome the above technical problems, the present invention designs and develops a multi-axis suspension axle assembly to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The embodiment of the present invention provides a multi-axis suspension axle assembly to solve the problem that as people's living standards continue to improve, toy cars are no longer limited to simply imitating the appearance of real vehicles but cannot drive automatically, and the age distribution of toy car players is gradually expanding, and the experience required for simulated vehicles is also enhanced. As a result, most existing simulated vehicles, such as simulated trailers, not only drive on flat roads, but also drive on complex roads such as in the wild and muddy areas to imitate the functions of real trailers. However, the size and height of the simulated trailer are ultimately much lower than those of the real trailer. When encountering speed bumps on the road or earth slopes in the wild, it is ultimately impossible to drive smoothly like a real trailer by relying on its own height and power. Therefore, the axle at the bottom of the simulated trailer is very likely to be stuck or worn by roadblocks, which greatly reduces the service life and cost of the simulated trailer.

[0035] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems. The overall idea is as follows: by setting an adjustment component, the height of the multi-axis suspension axle can be adjusted as a whole without affecting the normal driving of the wheel 1. Compared with most existing simulated suspension vehicles, when encountering speed bumps or earth slopes in the wild, the height of the axle can be adjusted according to the usage situation to allow the vehicle to pass safely.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] The present invention provides a multi-axis suspension axle assembly, comprising:

[0038] A multi-axis axle; wheels 1 are rotatably connected on both sides of the multi-axis axle;

[0039] Adjustment component; the adjustment component is arranged in the middle part of the multi-axis axle and is used to adjust the height of the multi-axis suspension axle.

[0040] As the age distribution of players gradually expands, the experience required for simulated vehicles also increases, so that the simulated trailer will not only travel on flat roads, but also travel on some complex roads such as the wild and muddy land to imitate the functions of a real trailer. However, the size and height of the simulated trailer are much lower than those of the real trailer. When encountering speed bumps on the road or dirt slopes in the wild, it cannot pass smoothly like a real trailer by relying on its own height and power. The present invention adjusts the height of the multi-axis suspension axle as a whole by setting an adjustment component without affecting the normal driving of the wheel 1. Compared with most existing simulated suspension vehicles, when encountering speed bumps or dirt slopes in the wild, the height of the axle can be adjusted according to the usage situation to allow the vehicle to pass safely, so that the simulated trailer can travel smoothly on complex roads such as the wild or muddy land during driving, thereby increasing the pass rate of the simulated trailer on the above roads, thereby increasing the service life of the simulated trailer while controlling the cost.

[0041] As a specific embodiment of the present invention, the multi-axis axle comprises:

[0042] Four connecting shafts 2, both ends of which are fixedly connected to a No. 1 gear 21; the distance between every two adjacent connecting shafts 2 is equal;

[0043] A fixing rod 3 is provided inside the fixing rod 3 with a sliding groove 31, and a side wall of the sliding groove 31 is provided with teeth that match the shape and size of the number one gear 21; a fixing rod 3 is provided outside the number one gear 21, and the number one gear 21 is placed in the sliding groove 31 with teeth that match the shape and size of the number one gear 21.

[0044] The No. 1 gear 21 at both ends of the four connecting shafts 2 is located in a sliding groove 31 opened inside the fixing rod 3, and the side wall of the sliding groove 31 is provided with teeth that match the shape and size of the No. 1 gear 21. Therefore, when the connecting shaft 2 rotates, the gears at both ends of the connecting shaft 2 will drive the connecting shaft 2 to move up and down in the sliding groove 31 under the action of the teeth that match the shape and size of the No. 1 gear 21 opened on the side wall of the sliding groove 31, and the distance between each two adjacent connecting shafts 2 is equal to ensure that the connecting shafts 2 do not interfere with each other.

[0045] As a specific embodiment of the present invention, the adjustment component includes:

[0046] A connecting frame 4, wherein a placement slot 41 is provided in the connecting frame 4; the four connecting shafts 2 all penetrate the connecting frame 4 and are rotatably connected thereto;

[0047] The second gear 5, the four connecting shafts 2 are located in the placement groove 41 and are fixedly connected to the second gear 5;

[0048] A third gear 6 is meshed between the second gears 5 on each two adjacent connecting shafts 2; the third gear 6 is located in the placement slot 41;

[0049] Motor 7, the outer side of the middle part of the connecting frame 4 is fixedly connected with the motor 7, and the output shaft of the motor 7 passes through the side wall of the connecting frame 4 and is fixedly connected with the third gear 6 in the middle part of the placement groove 41;

[0050] A rectangular rod 8, with rectangular rods 8 fixedly connected to both sides of the top of the connecting frame 4;

[0051] A limiting groove 81 is provided on the inner side wall of the sliding groove 31 ; the width of the limiting groove 81 is smaller than the width of the sliding groove 31 and is equal to the width of the rectangular rod 8 .

[0052] The four connecting shafts 2 are connected into a whole through the connecting frame 4. When the vehicle encounters a speed bump on the road or encounters a soil slope in the wild, the motor 7 fixedly connected to the outer side of the middle part of the connecting frame 4 is started, and the output shaft of the motor 7 passes through the side wall of the connecting frame 4 to drive the No. 3 gear 6 in the middle part of the placement groove 41 to rotate, and the No. 3 gear 6 in the middle part of the placement groove 41 drives the No. 2 gears 5 on both sides thereof to rotate, and the connecting shafts 2 fixedly connected inside the No. 2 gears 5 on both sides of the No. 3 gear 6 in the middle part of the placement groove 41 rotate at the same time. When the two connecting shafts 2 in the middle part rotate, the No. 2 gears 5 fixedly connected thereto simultaneously drive the two No. 3 gears meshing therewith and away from the motor 7. 6 rotates, and the two No. 3 gears 6 far away from the motor 7 rotate, driving the two No. 2 gears 5 at the two ends meshing with them to rotate, and the rotation of the No. 2 gears 5 at the two ends drives the connecting shafts 2 at the two ends to rotate, so that when the motor 7 is turned on, the four connecting shafts 2 rotate at the same time. When the four connecting shafts 2 rotate, the gears at both ends of the connecting shafts 2 will drive the four connecting shafts 2 to move up and down in the sliding groove 31 at the same time under the action of the teeth that are matched with the shape and size of the No. 1 gear 21 on the side wall of the sliding groove 31, so as to adjust the height of the connecting shaft 2 and the ground so that it can pass through the speed bump or the earth slope. When the connecting shaft 2 moves up and down, the connecting frame 4 will move up and down synchronously with it, and the connecting frame 4 will move up and down normally. When moving downward, the rectangular rod 8 slides up and down in the limit groove 81, thereby providing a certain limit to the fixed rod 3 so that the fixed rod 3 will not rotate; thereby, on the one hand, ensuring that the first gear 21 can move up and down normally in the fixed rod 3, and on the other hand, ensuring the normal operation of the wheel 1; the four connecting shafts 2 can move up and down to achieve the overall distance adjustment of the multi-axis axle, when encountering a higher roadblock, the multi-axis axle is raised, and when passing the roadblock, the multi-axis axle is lowered, and the multi-axis axle is adjusted in distance without affecting the normal operation of the wheel 1, so that the probability of passing on a complex road surface is increased, and the probability of the multi-axis axle being damaged by the roadblock is reduced; and the present invention is used for simulating toy trailers Therefore, the cargo weight of the trailer is relatively low. At the same time, when encountering a roadblock, the present invention adjusts the No. 1 gear 21 to move upward in the sliding groove 31 to achieve the height adjustment of the multi-axis axle. When passing through the roadblock, the No. 1 gear 21 is adjusted to the lowest point of the sliding groove 31 to fit the inner bottom surface of the fixed rod 3, so that the trailer is supported by the meshing between the No. 1 gear 21 and the sliding groove 31 through the engagement between the gears and the teeth when passing through the roadblock. When the trailer is driving normally, the vehicle body is supported by the fixed rod 3. For the simulated toy trailer, its own weight and cargo capacity are relatively light, thereby reducing the possibility of failure of the No. 1 gear 21 and the motor 7 and increasing the service life.

[0053] As a specific implementation of the present invention, the third gear 6 in the placement slot 41 is rotatably connected to the side wall of the connecting frame 4 through a rotating rod 9.

[0054] The upper and lower third gears 6 in the placement slot 41 are rotatably connected to the side walls of the connecting frame 4 through the rotating rod 9, ensuring that the upper and lower third gears 6 in the placement slot 41 rotate more smoothly with the assistance of the rotating rod 9 during rotation, thereby improving the stability of the equipment.

[0055] As a specific embodiment of the present invention, a cargo bin 10 is provided above the connecting frame 4; two rectangular blocks 11 are fixedly connected to the upper surfaces at both ends of the connecting frame 4; through slots 111 are provided in the rectangular blocks 11; the through slots 111 connect the front and rear ends of the rectangular blocks 11; a baffle 112 is fixedly connected to the middle position of the through slot 111; two springs 113 are fixedly connected to the two ends of the side walls of the outer surface of the baffle 112 respectively; the other ends of the springs 113 are fixedly connected to a clamp 114; the outer surfaces of the plurality of clamps 114 are slidably connected to the through slots 111; a groove 101 of the same shape and size is provided on the outer surface of the lower end of the cargo bin 10 and at a position corresponding to the rectangular block 11 at the upper end of the connecting frame 4.

[0056] Two rectangular blocks 11 are fixedly connected to the upper surfaces of both ends of the connecting frame 4, and grooves 101 of the same shape and size are opened on the outer surface of the lower end of the cargo bin 10 at positions corresponding to the rectangular blocks 11 at the upper end of the connecting frame 4. At the same time, the front and rear ends of each rectangular block 11 are opened with a through groove 111 that connects the front and rear ends of the rectangular block 11, and a baffle 112 is fixedly connected at the middle position of the through groove 111. Springs 113 are fixed to the outer surfaces of both sides of the baffle 112, and the other ends of the springs 113 are fixed with clamping heads 114. The corresponding grooves 101 are also respectively provided with clamping grooves of the same shape and size. The clamping grooves of the cargo bin 10 can be clamped on the rectangular block 11 through the clamping heads 114. When replacement is required, it is only necessary to apply an upward pulling force to the cargo bin 10 that has been installed on the upper end of the base. At this time, the outer surface of the groove 101 squeezes the clamping heads 114 inwards, because the springs 113 at the rear ends have The clamp head 114 is elastic, so that the clamp head 114 can be smoothly retracted into the through slot 111, thereby ensuring that the clamping slot opened in the groove 101 and the clamping head 114 can be smoothly separated. When the cargo compartment 10 needs to be installed, it is only necessary to align the groove 101 at the lower end of the cargo compartment 10 that needs to be replaced with the position of the rectangular block 11, and then press the cargo compartment 10 downward. At this time, the side wall of the groove 101 causes the clamping head 114 to retract into the through slot 111 again until the cargo compartment 10 is completely installed. At this time, the position of the clamping slot in the groove 101 is relative to the clamping head 114. Because the diameter and size of the clamping slot are equal to the front end of the clamping head 114, there is enough reserved space at the front end of the clamping head 114, so that the clamping head 114 pops outward under the action of the spring 113 until the outer surface of the front end of the clamping head 114 fits with the clamping slot, and the clamping head 114 and the clamping slot further ensure the stability of the cargo compartment 10, thereby meeting the use needs of different players for the simulated trailer.

[0057] As a specific embodiment of the present invention, the front end of the outer surface of the clamp head 114 is hemispherical; a hemispherical clamping groove with the same diameter and size as the outer surface of the front end of the clamp head 114 is opened at a position corresponding to the clamp head 114 on the outer surface side wall of the rectangular block 11 in the groove 101.

[0058] The front end of the outer surface of the clamp head 114 is set to be hemispherical, and a hemispherical clamping groove with the same diameter and size as the outer surface of the front end of the clamp head 114 is opened at the position corresponding to the clamp head 114 on the outer surface side wall of the rectangular block 11 in the groove 101, so that the movement of the clamp head 114 in the clamping groove is smoother.

[0059] As a specific implementation of the present invention, the connecting frame 4 and the connecting shaft 2 are made of aluminum alloy material.

[0060] Because aluminum alloy materials will form an oxide film on their outer surface when they come into contact with air, thereby improving the corrosion resistance of aluminum alloy, and the main force-bearing parts such as the connecting frame 4 and the connecting shaft 2 are made of aluminum alloy materials, the service life of the simulated trailer is greatly increased. At the same time, aluminum alloy materials have the characteristics of light weight and high strength, which avoids damage to the simulated trailer due to possible bumps during driving.

[0061] As a specific embodiment of the present invention, an adjustment hole 12 is opened at one end of the connecting frame 4, and an adjustment shaft 13 is slidably connected in the adjustment hole 12. The upper and lower ends of the adjustment shaft 13 are fixedly connected to an arc rod, and the adjustment shaft 13 is located inside the arc rod.

[0062] An adjustment hole 12 is provided at one end of the connecting frame 4 to ensure that the connecting frame 4 can slide up and down on the adjustment shaft 13, so that the connecting frame 4 can adjust the distance up and down normally, so that the adjustment shaft 13 does not affect the adjustment of the connecting shaft 2, ensuring the normal use of the multi-axis axle height adjustment function.

[0063] As a specific implementation of the present invention, the side end of the arc rod is fixedly connected to the headstock 15 by screws.

[0064] The side end of the arc rod is fixedly connected to the headstock 15 by screws, which can facilitate the disassembly of the arc rod, and the adjustment shaft 13 fixedly connected inside the arc rod can also be disassembled together with it; thereby ensuring that the connecting frame 4 that can slide up and down on the adjustment shaft 13 can be disassembled.

[0065] As a specific implementation of the present invention, the cargo compartment 10 is made of PA plastic.

[0066] Because PA plastic has the characteristics of low melting point and easy regeneration, the cargo bin 10 is made of PA plastic, which can be recycled and reused to make cargo bins 10 of different shapes. At the same time, the cargo bin 10 made of PA plastic is relatively light in weight, thereby reducing the pressure on the connecting frame 4 and the connecting shaft 2.

[0067] Working principle: When the vehicle encounters a speed bump on the road or encounters a dirt slope in the wild, the motor 7 fixedly connected to the outer middle part of the connecting frame 4 is started at this time, and the output shaft of the motor 7 passes through the side wall of the connecting frame 4 to drive the No. 3 gear 6 in the middle part of the placement slot 41 to rotate, and the No. 3 gear 6 in the middle part of the placement slot 41 drives the No. 2 gear 5 on both sides thereof to rotate, and the No. 3 gear 6 in the middle part of the placement slot 41 and the No. 2 gear 5 on both sides thereof and the connecting shaft 2 fixedly connected thereto rotate at the same time, and when the two connecting shafts 2 in the middle part rotate, the No. 2 gear 5 fixedly connected thereto simultaneously drives the two No. 3 gears 6 meshing therewith and away from the motor 7 to rotate, and when the two No. 3 gears 6 away from the motor 7 rotate, they drive the No. 2 gears 5 at the two ends meshing therewith to rotate, and the rotation of the No. 2 gears 5 at the two ends drives the connecting shafts 2 at the two ends to rotate, so that when the motor 7 is turned on, the four connecting shafts 2 rotate at the same time, and when the four connecting shafts 2 rotate, the gears at both ends of the connecting shaft 2 will be in the sliding slot 31 The teeth on the side wall that match the shape and size of the No. 1 gear 21 drive the four connecting shafts 2 to move up and down in the sliding groove 31 at the same time, thereby adjusting the height of the connecting shaft 2 and the ground so that it can pass through a speed bump or a dirt slope. When the connecting shaft 2 moves up and down, the connecting frame 4 will move up and down synchronously with it. When the connecting frame 4 moves up and down normally, the rectangular rod 8 slides up and down in the limiting groove 81, thereby providing a certain limit to the fixed rod 3 so that the fixed rod 3 does not rotate, thereby ensuring that the No. 1 gear 21 can move up and down normally in the fixed rod 3 on the one hand, and ensuring the normal operation of the wheel 1 on the other hand; the four connecting shafts 2 can move up and down, thereby realizing the overall distance adjustment of the multi-axis axle, when encountering a higher roadblock, the multi-axis axle is raised, and when passing through the roadblock, the multi-axis axle is lowered. The multi-axis axle can achieve distance adjustment without affecting the normal operation of the wheel 1, thereby increasing the probability of passing on a complex road surface and reducing the probability of the multi-axis axle being damaged by the roadblock.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
