Description

Technical Field

[0001] This utility model relates to the technical field of automotive leaf spring installation equipment, specifically an energy-saving and environmentally friendly automotive rear frame rear leaf spring support structure. Background Technology

[0002] Leaf springs are the most traditional elastic elements in automotive suspension systems. They are widely used due to their high reliability, simple structure, short manufacturing process, low cost, and simplified design. Leaf springs are typically mounted on the vehicle frame via leaf spring supports. These supports are a key component of the vehicle chassis, serving to support and secure the leaf springs; their quality directly affects the safety of the entire vehicle.

[0003] The leaf spring supports used in the prior art are usually of a fixed width. However, due to the different widths of leaf springs, the leaf spring supports are prone to mismatch with the width of the leaf springs during use. Therefore, it is necessary to select leaf spring supports of other widths to fit the leaf springs that require the corresponding needs. This results in poor applicability of the supports and makes it difficult to meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving and environmentally friendly rear leaf spring support structure for automobiles, which can be adapted to leaf springs of different widths and is suitable for various vehicle models and purposes. It eliminates the need to design and manufacture special supports for each width of leaf spring, thus making this support more practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and environmentally friendly automotive rear frame leaf spring support structure, comprising a mounting panel, a connecting panel fixed to the surface of the mounting panel, a mounting shell fixed to the surface of the connecting panel, reinforcing ribs fixed to the surface of the mounting shell, the reinforcing ribs being fixedly connected to the surface of the mounting panel, multiple fixing bolt holes on the surface of the mounting panel, a combined panel on one side of the mounting shell, two reinforcing plates fixed to the surface of the combined panel, a receiving groove for use with the reinforcing plates on the surface of the mounting shell, the reinforcing plates being slidably connected to the inner wall of the receiving groove, a combined shell fixed to the top of the mounting shell, a lead screw threaded through the surface of the combined shell, a connecting rod fixed to the surface of the lead screw, the connecting rod slidingly penetrating the combined panel, a limit structure on the surface of the connecting rod, a sleeve slidably connected to the surface of the connecting rod, a handle on the surface of the sleeve, and shaft holes on both the surface of the connecting panel and the combined panel.

[0006] As a preferred embodiment of the energy-saving and environmentally friendly rear leaf spring support structure for automotive rear frames of this utility model, the connecting rod surface limiting structure includes two lower connecting plates, an upper connecting plate is provided above the lower connecting plates, the surface of the connecting rod is provided with a limiting groove for use with the lower connecting plates and the upper connecting plates, and the surfaces of the lower connecting plates and the upper connecting plates are provided with a combination hole.

[0007] As a preferred embodiment of the energy-saving and environmentally friendly rear leaf spring support structure for automotive rear frames of this utility model, an extension plate is fixed to the surface of the combined panel, and a first mounting hole is provided on the surface of both the connecting rod and the extension plate.

[0008] As a preferred embodiment of the energy-saving and environmentally friendly rear leaf spring support structure for automobile rear frames of this utility model, the connecting rod, the housing, and the handle are all provided with second mounting holes.

[0009] As a preferred embodiment of the energy-saving and environmentally friendly rear leaf spring support structure for automobile rear frames of this utility model, the surface of the mounting panel is provided with shock-absorbing holes and weight-reducing grooves.

[0010] As a preferred embodiment of the energy-saving and environmentally friendly rear leaf spring support structure for automotive rear frames of this utility model, the mounting panel, connecting panel, mounting shell, reinforcing ribs, reinforcing plates, and combined panel are all made of aluminum alloy, and the surfaces of the mounting panel, connecting panel, mounting shell, reinforcing ribs, reinforcing plates, and combined panel are all coated with epoxy resin.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, rotating the handle causes the connecting rod to rotate the lead screw, which then slides along the inner wall of the assembly housing due to the threaded connection. During this process, the limiting structure on the surface of the connecting rod moves the assembly panel, allowing the assembly panel to slide along the inner wall of the mounting housing with the reinforcing plate. This design allows the spacing between the assembly panel and the connecting panel to be adjusted to accommodate leaf springs of different widths. It eliminates the need to design and manufacture dedicated supports for each leaf spring width. Furthermore, precise adjustment of the support width ensures close contact between most leaf springs and the inner wall of the support, improving shock absorption and reducing vibration and noise during operation.

[0019] Please see Figure 1-5 An energy-saving and environmentally friendly rear leaf spring support structure for automotive rear frames includes a mounting panel 1, a connecting panel 2 fixed to the surface of the mounting panel 1, a mounting shell 3 fixed to the surface of the connecting panel 2, a reinforcing rib 4 fixed to the surface of the mounting shell 3, the reinforcing rib 4 being fixedly connected to the surface of the mounting panel 1, the mounting shell 3 being fixedly connected to the surface of the mounting panel 1, a plurality of fixing bolt holes 5 being provided on the surface of the mounting panel 1, a combination panel 6 being provided on one side of the mounting shell 3, two reinforcing plates 7 being fixed to the surface of the combination panel 6, a receiving groove being provided on the surface of the mounting shell 3 for use with the reinforcing plates 7, the reinforcing plates 7 being slidably connected to the inner wall of the receiving groove, a combination shell 9 being fixed to the top of the mounting shell 3, a lead screw 10 being threaded through the surface of the combination shell 9, a connecting rod 11 being fixed to the surface of the lead screw 10, the connecting rod 11 being slidably through the combination panel 6, a limit structure being provided on the surface of the connecting rod 11, a sleeve 12 being slidably connected to the surface of the connecting rod 11, a handle 13 being provided on the surface of the sleeve 12, and shaft holes 8 being provided on the surfaces of both the connecting panel 2 and the combination panel 6.

[0020] The fixing bolt hole 5 is used for installation with bolts to the frame. The reinforcing diagonal rib 4 can enhance the overall structural strength of this support. When installing the leaf spring, the position of the combined panel 6 can be adjusted according to the width of the leaf spring. By rotating the handle 13, the connecting rod 11 drives the lead screw 10 to rotate, so that the lead screw 10 can slide on the inner wall of the combined housing 9 due to the thread. During this process, the limiting structure on the surface of the connecting rod 11 can drive the combined panel 6 to move together, so that the combined panel 6 can drive the reinforcing plate 7 to slide on the inner wall of the mounting housing 3. And because the combined panel 6 and the surface of the connecting rod 11 are slidably connected, the connecting rod 11 is not easily pulled. The movable combination panel 6 rotates, and the design of the reinforcing plate 7 not only increases the structural strength of the combination panel 6, but also allows the combination panel 6 to achieve a straight guiding effect. Through this design, the distance between the combination panel 6 and the connecting panel 2 can be adjusted to accommodate leaf springs of different widths. There is no need to design and manufacture special supports for each width of leaf spring. At the same time, by precisely adjusting the width of this support, it can ensure that most of the leaf springs are in close contact with the inner wall of the support, improving the shock absorption effect and reducing vibration and noise during driving. After the leaf spring is installed between the connecting panel 2 and the combination panel 6, the installation operation of the leaf spring can continue through the shaft hole 8.

[0021] Furthermore, the surface limiting structure of the connecting rod 11 includes two lower connecting plates 16, an upper connecting plate 17 is provided above the lower connecting plates 16, a limiting groove 18 is opened on the surface of the connecting rod 11 to cooperate with the lower connecting plates 16 and the upper connecting plate 17, and a combination hole is opened on the surface of the lower connecting plates 16 and the upper connecting plate 17.

[0022] This design allows the lower connecting plate 16 and the upper connecting plate 17 to be locked onto the surface of the limiting groove 18 and fixed by mounting bolts through the combination holes. This allows the combined panel 6 to be limited on the surface of the connecting rod 11, preventing the combined panel 6 from sliding back and forth on the surface of the connecting rod 11.

[0023] Furthermore, an extension plate 19 is fixed to the surface of the combination panel 6, and the first mounting hole 20 is opened on the surface of both the connecting rod 11 and the extension plate 19.

[0024] After the lead screw 10 is rotated to the appropriate position, the lead screw 10 can be limited by passing a bolt through the first mounting hole 20 on the surface of the extension plate 19 and the connecting rod 11 and installing a nut, so as to prevent the lead screw 10 from rotating during vehicle operation.

[0025] Furthermore, the connecting rod 11, the sleeve 12 and the handle 13 are all provided with second mounting holes 21;

[0026] With this design, when the housing 12 is installed on the surface of the connecting rod 11 and the handle 13 is located on the surface of the housing 12, the second mounting hole 21 on the surface of the connecting rod 11, housing 12 and handle 13 can be bolted through and nuts installed, thereby allowing the housing 12 and handle 13 to be disassembled from the connecting rod 11, so that the bracket occupies less volume and weight after the handle 13 is removed.

[0027] Furthermore, the surface of the mounting panel 1 is provided with shock-absorbing holes 14 and weight-reducing grooves 15;

[0028] The design of the shock-absorbing hole 14 and the weight-reducing groove 15 can reduce the overall weight of this support, thereby reducing the total weight of the vehicle. This design helps to improve fuel economy and reduce fuel consumption and emissions.

[0029] Furthermore, the mounting panel 1, connecting panel 2, mounting shell 3, reinforcing rib 4, reinforcing plate 7, and combined panel 6 are all made of aluminum alloy, and the surfaces of the mounting panel 1, connecting panel 2, mounting shell 3, reinforcing rib 4, reinforcing plate 7, and combined panel 6 are all coated with epoxy resin.

[0030] Aluminum alloys have a low density, which helps reduce vehicle weight and improve fuel economy. Furthermore, aluminum alloys are fully recyclable, which is beneficial for resource recycling. Epoxy resin coatings have a low content of volatile organic compounds, which meets environmental protection requirements. In addition, epoxy resin coatings have high hardness, which can resist scratches and wear and extend the service life of parts.

[0031] Working principle: When installing the leaf spring, the position of the combination panel 6 can be adjusted according to the width of the leaf spring. By rotating the handle 13, the lead screw 10 can slide on the inner wall of the combination housing 9 due to the thread. During this process, the limiting structure on the surface of the connecting rod 11 can drive the combination panel 6 to move together, so that the combination panel 6 can drive the reinforcing plate 7 to slide on the inner wall of the mounting housing 3. Through this design, the distance between the combination panel 6 and the connecting panel 2 can be adjusted to accommodate leaf springs of different widths. There is no need to design and manufacture special supports for each width of leaf spring. At the same time, by precisely adjusting the width of this support, it can ensure that most of the leaf springs are in close contact with the inner wall of the support, improving the shock absorption effect and reducing vibration and noise during driving.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
