Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, and in particular to a novel independent rear suspension fixing device. Background Technology

[0002] The suspension mount itself is a sheet metal part used to connect the suspension shock absorber and the vehicle body, and it is a force transmission path between the suspension and the vehicle body.

[0003] The MacPherson strut independent suspension's shock absorbers also serve a guiding function, with the sprung mass entirely loaded onto the mounting bracket. The mounting bracket becomes a critical stress point, subjected to radial, axial, and torsional forces, and experiences impact loads during high-speed tire movement. This places high demands on the strength of the suspension mounting bracket. Simply increasing the material thickness and steel strength of the rear suspension mounting bracket would negatively impact production costs and overall vehicle economy. Therefore, we propose a novel independent rear suspension mounting device. Utility Model Content

[0029] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0030] Example:

[0031] like Figures 1-4 As shown, a novel independent rear suspension fixing device includes a damper body 1. Both ends of the damper body 1 are fixedly connected to connecting fixing seats 2. A buffer spring 3 is provided between the connecting fixing seats 2. A connecting bottom rod 4 is fixedly connected to the side of the connecting fixing seat 2 located at the output end of the damper body 1 away from the damper body 1. A fixing connector 8 is fixedly provided on the outer side of the end of the connecting bottom rod 4 away from the connecting fixing seat 2. A connecting mounting seat 5 is fixedly connected to the side of the connecting fixing seat 2 located at the end of the damper body 1 away from the output end. A protective guide mechanism 6 and a connecting protective mechanism 7 are symmetrically provided on the outer side of the connecting fixing seat 2.

[0032] The working principle of the above technical solution is as follows:

[0033] During use, the connecting fixed base 2 can improve the overall load-bearing capacity, thereby improving the overall stability of use. Furthermore, under the action of the protective guide mechanism 6 and the connecting protective mechanism 7, the buffer spring 3 can be restricted, preventing the buffer spring 3 from tilting and extending outward when subjected to force and contraction, so that the whole can be used stably and is easy to operate.

[0034] In another embodiment, such as Figure 2 As shown, the connecting mounting base 2 includes a connecting mounting plate 21. A fixed connecting column 22 is fixedly connected to the side of the connecting mounting plate 21 away from the damper body 1. A connecting mounting plate 23 is fixedly connected to the other side of the fixed connecting column 22. Connecting reinforcing blocks 24 are symmetrically provided between the side of the connecting mounting plate 23 that is close to the connecting mounting plate 21 and the outer side of the fixed connecting column 22.

[0035] The reinforcement block 24 facilitates the connection and enhances the strength of the connecting mounting plate 21, the fixed connecting column 22, and the connecting mounting plate 23, enabling the whole structure to be used stably and conveniently.

[0036] In another embodiment, such as Figure 2 As shown, a number of reinforcing support rods 25 are provided at equal intervals between the connecting mounting plate 21 and the connecting mounting plate 23.

[0037] This design allows for stable support between the connecting mounting plate 21 and the connecting mounting plate 23, thanks to the reinforcement support rod 25, and facilitates operation.

[0038] In another embodiment, such as Figure 2 As shown, the mounting plate 21 has symmetrically provided fixing slots 26 on the side near the damper body 1.

[0039] The fixed slot 26 facilitates the installation of the protective guide mechanism 6 and the connecting protective mechanism 7, making operation convenient.

[0040] In another embodiment, such as Figure 3 As shown, the protective guide mechanism 6 includes a first locking block 61 that is movably engaged with the inner side of the fixed locking slot 26. A movable protective arc plate 62 is fixedly connected to the bottom of the first locking block 61. The edges of the movable protective arc plate 62 are provided with first end blocks 63. The sides of the first end blocks 63 are symmetrically provided with first semi-circular grooves 64. A first movable sleeve block 65 is movably sleeved on the outer surface of the first end block 63. The surface of the first movable sleeve block 65 is symmetrically provided with first threaded holes 66. The inner side of the first threaded hole 66 is movably connected with a first fastening bolt 68 through a thread. One end of the first fastening bolt 68 is movably engaged with the inner side of the first semi-circular groove 64. A fixed guide hole 67 is provided at the bottom of the movable protective arc plate 62.

[0041] The first locking block 61 is easily inserted into the inner side of the fixed slot 26, so that the movable protective arc plate 62 can be fitted onto the outer side of the buffer spring 3. Then, the first movable sleeve block 65 is fitted onto the outer side of the surface of the first end block 63, and the first fastening bolt 68 is rotated and inserted into the inner side of the first threaded hole 66 and the first semi-circular groove 64, thereby achieving stable installation and fixation, which is convenient to operate.

[0042] In another embodiment, such as Figure 3 As shown, the connecting protection mechanism 7 includes a second locking block 71, a connecting mounting block 72 fixedly connected to the top of the second locking block 71, a connecting protection insert rod 73 provided on the top of the connecting mounting block 72, a second end block 74 provided at the end of the connecting mounting block 72, a second semi-circular groove 75 provided on one side of the second end block 74, a second movable sleeve block 76 movably sleeved on the outer surface of the second end block 74, a second threaded hole 77 provided on the surface of the second movable sleeve block 76, a second fastening bolt 78 connected to the inner side of the second threaded hole 77 by thread, and one end of the second fastening bolt 78 movably inserted into the inner side of the second semi-circular groove 75.

[0043] This facilitates the insertion of the connecting protective rod 73 into the inner side of the fixed guide hole 67, and allows the second locking block 71 to be engaged into the inner side of the fixed slot 26. Then, the second movable sleeve 76 is fitted onto the outer side of the surface of the second end block 74, and the second fastening bolt 78 is rotated and inserted into the inner side of the second threaded hole 77 and the second semi-circular groove 75, thereby achieving connection and fixation.

[0044] In another embodiment, such as Figure 3 and Figure 4 As shown, the outer side of the top surface of the connecting protective rod 73 slides and fits against the inner side of the fixed guide hole 67.

[0045] The outer surface of the end of the connecting protective rod 73 can slide stably inside the fixed guide hole 67, making operation convenient.

[0046] The working principle of this utility model is as follows: First, the connecting protective plug 73 is inserted into the inner side of the fixed guide hole 67. Then, the first locking block 61 and the second locking block 71 are both inserted into the inner side of the fixed slot 26. Next, the first movable sleeve 65 is fitted onto the outer surface of the first end block 63, and the first fastening bolt 68 is rotated and inserted into the inner side of the first threaded hole 66 and the first semi-circular groove 64. Then, the second movable sleeve 76 is fitted onto the outer surface of the second end block 74, and the second fastening bolt 78 is rotated and inserted into the inner side of the second threaded hole 77 and the second semi-circular groove 75. This allows for connection and fixation. When used as a whole, the connecting reinforcement block 24 and the reinforcing support rod 25 enhance the overall strength of the connecting mounting plate 21, the fixed connecting column 22, and the connecting mounting plate 23, ensuring stable use. Simultaneously, when the damper body 1 retracts, the buffer spring 3 compresses, causing a change in the distance between the first locking block 61 and the second locking block 71. This allows the connecting protective plug rod 73 to move inside the fixed guide hole 67, ensuring stable use. The overall structure is simple and the operation is convenient and quick.

[0047] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
