Description

Technical Field

[0001] The invention relates to the technical field of automobile front suspension, in particular to a left lower support for an automobile front suspension. Background Art

[0002] The front overhang refers to the horizontal distance between the center of the front wheel and the front end of the vehicle. The length of the front overhang should be sufficient to fix and install the engine, radiator, steering gear, etc. However, it should not be too long, otherwise the car's approach angle will be too small, and it will easily touch the ground when going uphill, affecting the car's passability.

[0003] In the prior art, for example, the "left and right front suspension brackets" of Chinese patent number CN112172503A include an upper bracket; the lower end of the upper bracket is hinged to the lower bracket below through a shock-absorbing spring; the left and right groups of upper brackets are interconnected through a load-bearing connecting rod; the middle shaft sleeve of the load-bearing connecting rod has a reinforcing hanging mechanism, and the left and right ends of the reinforcing hanging mechanism are respectively nested with the lower bracket on the corresponding side; a supporting mechanism is fixedly installed at the lower end position of the lower bracket which is hinged to the lower end of the shock-absorbing spring.

[0004] However, in the prior art, when a car is driving, its front suspension support is subjected to different forces. When these forces act on the front suspension support, the directions of the forces are also different. For example:

[0005] The vertical static load is the weight of the vehicle body and frame, the assembly load and the payload (passengers and cargo) mounted on the frame. This load causes the frame to bend and deform. When a vehicle is traveling at high speed on a level road, a symmetrical vertical dynamic load is generated. The value of this load depends on the vertical static load and acceleration, as well as the fact that this load causes the frame to bend and deform. In addition, when traveling on uneven roads, an obliquely symmetrical dynamic load is generated. Because the front and rear wheels are not in the same plane, the frame will tilt along with the body. At this time, this load will prevent the front suspension support from torsion deformation. The load's magnitude is related to the road conditions, the body, the frame and the stiffness of the frame. In addition, during a collision, the frame will also produce shear deformation in the horizontal direction, and local torsion will also occur.

[0006] When a car is driving, the front suspension supports in different directions need to work together to achieve the shock absorption effect. When a certain support is damaged, it will affect the overall shock absorption effect. A single front suspension support in a certain direction cannot absorb shock for different types of loads, which can easily cause the entire frame to bend and deform. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0035] Reference Figure 1-9 As shown: A vehicle front suspension lower left support, including a base 6, a first connecting plate 1, a second connecting plate 7, a first movable frame 4 and a second movable frame 5, both sides of the base 6 are fixedly connected to side plates 62, both sides of the first connecting plate 1 are fixedly connected to the bottom of the first support plate 11, one side of the first support plate 11 is fixedly connected to a fixing rod 13, a first shock absorbing mechanism 2 is provided above the side plate 62, and second shock absorbing mechanisms 3 are provided on both sides of the first movable frame 4 and the second movable frame 5;

[0036] The first shock absorbing mechanism 2 includes a first damper 27, a movable assembly 21, a fixed frame 24, a second movable rod 23, and a second movable member 28. One side of the fixed frame 24 is fixedly connected to the side plate 62. A rotating shaft 241 is provided on the inner side of the fixed frame 24. The second movable rod 23 is sleeved on the surface of the rotating shaft 241. The second movable member 28 is sleeved on the surface of the fixed rod 13. One side of the first damper 27 is fixedly connected to a first limiting plate 271. The other side of the first damper 27 is fixedly connected to a second limiting plate 272. One side of the first limiting plate 271 is fixedly connected to the first movable member 25.

[0037] The movable component 21 includes a mounting shell 217 and a movable head 212. One side of the mounting shell 217 is fixedly connected to the second movable rod 23. A second limiting groove 216 is provided on the inner wall of the mounting shell 217. A first limiting groove 213 is provided on the movable head 212. One end of the movable head 212 is fixedly connected to the connecting rod 211. One end of the connecting rod 211 is fixedly connected to the first movable rod 22. The inner side of the first movable rod 22 is movably connected to the first movable part 25.

[0038] In this embodiment, first, the movable head 212 can rotate freely within the limiting housing 215. When the movable head 212 rotates, the connecting rod 211 fixedly connected thereto also changes its angle. In addition, because the limiting ball 214 is within the first limiting groove 213 and the second limiting groove 216, and is located within the mounting hole 218 on the surface of the limiting housing 215, when the movable head 212 is freely adjusted and rotated, it can drive the limiting ball 214 to move under the limitation of the limiting housing 215 and the first limiting groove 213, and the limiting ball 214 will move within the second limiting groove 216, so that the angle of the first movable rod 22 can be changed.

[0039] Then, because the first movable rod 22 is connected to the first movable part 25, based on the existence of the movable component 21, the first damper 27 can change its angle at will, and after the first damper 27 is subjected to load, the first limit plate 271 and the second limit plate 272 can squeeze the first shock-absorbing spring 26. At this time, the first shock-absorbing spring 26 will store energy, and the first damper 27 can provide damping force.

[0040] Finally, the first shock-absorbing spring 26 consumes energy with damping force during multiple compression and release processes to achieve a shock-absorbing function; and when subjected to obliquely symmetrical dynamic loads or loads other than the vertical direction, its shock-absorbing effect can also be guaranteed. Example

[0041] Figure 5-8As shown, a first shock-absorbing spring 26 is sheathed on the surface of the first damper 27. The first shock-absorbing spring 26 is movably fixedly connected to the first limiting plate 271. The other end of the first shock-absorbing spring 26 is connected to the second fixing plate 36. A limiting housing 215 is disposed within the mounting housing 217. The movable head 212 is disposed within the limiting housing 215. A plurality of mounting holes 218 are formed on the surface of the limiting housing 215. A limiting ball 214 is disposed within the mounting holes 218. The two ends of the limiting ball 214 are respectively located within the first limiting groove 213 and the second limiting groove 216. The second shock absorbing mechanism 3 includes a second damper 34, a first fixed plate 33, and a second fixed plate 36. One end of the second damper 34 is connected to the first fixed plate 33, and the other end is connected to the second fixed plate 36. One side of the first fixed plate 33 is fixedly connected to the first connector 31, and the first center rod 32 is movably sleeved inside the first connector 31. One side of the second fixed plate 36 is fixedly connected to the second connector 38, and the second center rod 37 is movably sleeved inside the second connector 38. One end of the first center rod 32 is fixedly connected to the second movable frame 5, and one end of the second center rod 37 is fixedly connected to the first movable frame 4. A second shock absorbing spring 35 is sleeved on the surface of the second damper 34. One end of the second shock absorbing spring 35 is fixedly connected to the first fixed plate 33, and the other end of the second shock absorbing spring 35 is fixedly connected to the second fixed plate 36. A mounting groove 61 is provided on the surface of the base 6, and a buffer mechanism 8 is provided inside the mounting groove 61. A first connecting frame 51 is fixedly connected to one side of the base 6, and the first connecting frame 51 is rotatably connected to the second movable frame 5. A second connecting frame 52 is fixedly connected to one side of the second movable frame 5, and the second connecting frame 52 is rotatably connected to the first movable frame 4.

[0042] In this embodiment, first, when the first connecting plate 1 is subjected to a load, the first connecting plate 1 can transmit the force to the mounting frame 41 and the first movable frame 4, so the first movable frame 4 will rotate after being subjected to the force, and make an arc motion with the connection between it and the second connecting frame 52 as the center of the circle.

[0043] Next, the second shock-absorbing mechanism 3 also deforms under force. During this process, the second connector 38 and the second center rod 37 are subjected to the force from the first movable frame 4. Because the second connector 38 and the second center rod 37 are movably connected, and one end of the first connector 31 is also movably connected to the first center rod 32 via a through hole, the second connector 38 transmits force to the second fixing plate 36. The second fixing plate 36 compresses the second shock-absorbing spring 35. When the second shock-absorbing spring 35 is subjected to force, it deforms to store energy. The second damper 34 then provides a damping force to dissipate the energy, achieving the shock-absorbing function.

[0044] Finally, because the first movable part 25 is sleeved on a rod body arranged on the inner side of one end of the first movable rod 22, and the second movable part 28 is sleeved on the surface of the fixed rod 13, when encountering vertical static loads and vertical dynamic loads, the first damper 27, the first shock-absorbing spring 26, the second damper 34 and the second shock-absorbing spring 35 can be used to simultaneously reduce shock, thereby improving the overall shock-absorbing effect of the device in dealing with vertical static loads and vertical dynamic loads. Example

[0045] according to Figure 7-9 As shown, the buffer mechanism 8 includes a slide bar 81, a movable frame 84, a linkage rod 83, and a rotating member 85. One side of the rotating member 85 is fixedly connected to the second movable frame 5. One end of the linkage rod 83 is rotatably connected to the rotation member 85, and the other end of the linkage rod 83 is rotatably connected to the movable frame 84. The movable frame 84 is movably sleeved on the surface of the slide bar 81. Both ends of the slide bar 81 are fixedly connected to the inner wall of the mounting groove 61. The surface of the slide bar 81 is covered with a buffer spring 82. One end of the buffer spring 82 is fixedly connected to the movable frame 84, and the other end of the buffer spring 82 is fixedly connected to the inner wall of the mounting groove 61. The second connecting plate 7 is fixedly connected to one side of the base 6. Two reinforcement rods 63 are fixedly connected to one side of the side plate 62. One end of the reinforcement rod 63 is fixedly connected to the base 6. The first movable frame 4 is fixedly connected to the mounting frame 41. Two second fixing plates 36 are fixedly mounted on the mounting frame 41. The bottom center of the first connecting plate 1 is fixedly connected to the two second support plates 12. The mounting frame 41 is fixedly connected to the fixing rods 13 on both sides.

[0046] In this embodiment, the first movable frame 4 can transmit force to the second movable frame 5 through the two second shock absorbing mechanisms 3. After the second movable frame 5 is subjected to the force, it also performs an arc motion, and the arc motion is centered at the connection point between the second movable frame 5 and the first connecting frame 51.

[0047] Next, when the second movable frame 5 makes an arc motion, it can squeeze the linkage rod 83. Because the two ends of the linkage rod 83 are rotatably connected to the rotating member 85 and the movable frame 84 respectively, the linkage rod 83 will push the movable frame 84 to move when it is squeezed, and then the movable frame 84 begins to slide on the surface of the slide rod 81. During the sliding process, the movable frame 84 will squeeze the buffer spring 82, so that the buffer spring 82 is squeezed and stores energy.

[0048] The friction generated by the sliding movement of the movable frame 84 on the surface of the slide bar 81 dissipates energy, and the multiple dampers work together to dissipate the energy stored in the buffer spring 82 through damping force. Therefore, during the multiple compression and reset processes, the buffer spring 82 is protected from excessive vertical loads that could damage the components.

[0049] Finally, when subjected to vertical static loads and vertical dynamic loads, on the basis of simultaneous shock absorption by the first damper 27, the first shock-absorbing spring 26, the second damper 34 and the second shock-absorbing spring 35, the addition of the buffer mechanism 8 further improves the buffering and shock absorption effect, and when the second shock absorption mechanism 3 and the buffer mechanism 8 work at the same time, multi-stage buffering and shock absorption can be constituted.

[0050] The usage and working principle of this device: First, when subjected to vertical static load and vertical dynamic load, synchronous shock absorption is performed through the first damper 27, the first shock-absorbing spring 26, the second damper 34 and the second shock-absorbing spring 35. On this basis, the addition of a buffer mechanism 8 can not only further improve the buffering and shock absorption effect, but also when the second shock absorption mechanism 3 and the buffer mechanism 8 work at the same time, a multi-stage buffering and shock absorption structure can be formed.

[0051] Because the first movable part 25 is sleeved on a rod body arranged on the inner side of one end of the first movable rod 22, and the first movable part 25 is movably sleeved on the surface of the rod body, and because the second movable part 28 is sleeved on the surface of the fixed rod 13, when the first limiting plate 271 and the second limiting plate 272 are squeezed and the first shock-absorbing spring 2 is subjected to force, the first damper 27 can be used to cope with vertical loads.

[0052] Because the movable head 212 can rotate freely within the limiting housing 215, when the movable head 212 rotates, the connecting rod 211 fixedly connected thereto will also change its angle. In addition, the limiting ball 214 is also within the first limiting groove 213 and the second limiting groove 216, and is located within the mounting hole 218 on the surface of the limiting housing 215. Therefore, when the movable head 212 is freely adjusted and rotated, it will be limited by the limiting housing 215 and the first limiting groove 213, driving the limiting ball 214 to move, and the limiting ball 214 will move within the second limiting groove 216, so that the angle of the first movable rod 22 can be changed.

[0053] Finally, the presence of the movable component 21 allows the first damper 27 to change its angle at will. After the first damper 27 is subjected to a load, the first limit plate 271 and the second limit plate 272 can squeeze the first shock-absorbing spring 26. At this time, the first shock-absorbing spring 26 will store energy. Because the first damper 27 can provide a damping force, the first shock-absorbing spring 26 consumes energy with a damping force during multiple compression and release processes to perform a shock-absorbing function. Therefore, even if the first connecting plate 1 is subjected to an obliquely symmetrical dynamic load or a load at other angles, the overall shock-absorbing function of the device can be guaranteed.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
