Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a lightweight automotive front side panel anti-collision support device. Background Technology

[0002] The front bulkhead side panel is an important component of a car's body structure. Located between the engine compartment and the passenger compartment, it primarily serves as structural support, partition, and a mounting base for related accessories. To ensure the vehicle's structural stability and collision safety during operation, the front bulkhead side panel needs to be connected to the body frame via reliable support devices.

[0003] With the development trend of automotive lightweighting technology, modern automotive design is increasingly pursuing lightweight components and compact structural design while ensuring safety performance. This poses a dual challenge to the support device of the front side panel: on the one hand, the support device needs to be strong enough to ensure the installation stability of the front side panel under complex working conditions; on the other hand, the support device also needs to play the role of energy absorption and buffer in the event of a frontal or side-front collision.

[0004] Existing front bulkhead side panel support devices often fail to balance the above two points in their structural design. Many support solutions only provide rigid connections or simple reinforcing rib structures. Although this ensures the stability of the installation, in the event of a collision, such rigid supports are almost unable to absorb energy. This causes the impact force to be rapidly transmitted to the rear engine area, which can easily damage core components such as the engine, resulting in poor safety protection capabilities.

[0005] To improve cushioning performance, some solutions have attempted to incorporate simple rubber buffer blocks or one-way compression springs into the support structure. However, these designs generally have a short energy absorption stroke and limited cushioning effect, making them unsuitable for handling collisions with large impact forces. Especially under the design requirements of lightweighting and compactness, how to integrate a crash protection support structure that can both ensure installation stability and achieve efficient and complex energy absorption within a limited structural space is a core problem that urgently needs to be solved in the design of automotive front side panels.

[0006] Therefore, this invention proposes a lightweight automotive front side panel anti-collision support device to address the shortcomings of existing technologies. Summary of the Invention

[0007] In view of the problems of insufficient installation structure stability and single buffer energy absorption structure in the existing lightweight automotive front side panel anti-collision support device, which is difficult to effectively cope with large impact forces, the present invention aims to provide a lightweight automotive front side panel anti-collision support device with improved structure that can effectively solve the above problems.

[0008] This invention provides a lightweight automotive front side panel anti-collision support device, comprising: a stable installation mechanism, the stable installation mechanism including a U-shaped support base plate, the U-shaped support base plate having an installation groove, and an installation limiting block being engaged in the installation groove to jointly fix the front side panel a; and an anti-collision mechanism.

[0009] The anti-collision mechanism includes a support column serving as a motion track and a sliding seat slidably connected to the support column. Furthermore, the support column is also provided with a support frame for supporting it.

[0010] Furthermore, the anti-collision mechanism also includes a fixed seat fixed to the support column, with a rotating rod rotatably connected inside the fixed seat. One end of the rotating rod is connected to a support seat that abuts against the front side panel a. The anti-collision mechanism also includes an elastic component driven by the sliding seat. The elastic component includes a telescopic spring a, a support plate, and a telescopic spring b. The support plate provides support for the telescopic spring b. The sliding seat can push the telescopic spring a to slide to both sides, while simultaneously compressing the telescopic spring b in the center. This complex combination of linkage and spring compression achieves efficient energy absorption.

[0011] Preferably, the lightweight automotive front side panel anti-collision support device further includes rubber anti-collision posts, which are installed on the outside of the front side panel a as the first buffer barrier, used to be the first to contact and absorb the initial impact energy when a collision occurs, thus providing direct protection for the front side panel a itself.

[0012] Preferably, the rotating rod is rotatably mounted inside the fixed base via a shaft. This pivotal connection design ensures that the impact force received by the support base can be smoothly and unobstructedly transmitted to the subsequent sliding energy-absorbing structure, guaranteeing a smooth force transmission path.

[0013] Preferably, the support is fixedly connected to one end of the rotating rod and abuts against the rear side of the front side panel a. The arrangement makes the support a key node in the force transmission path, specifically used to receive and transmit the collision force transmitted from the front side panel a.

[0014] Preferably, the stable installation mechanism further includes a supporting column and reinforcing ribs. Specifically, the supporting column is disposed on the U-shaped supporting base plate, while the reinforcing ribs are connected between the supporting column and the U-shaped supporting base plate, forming a stable reinforcing structure that jointly strengthens the supporting rigidity of the front side panel a and improves the reliability of installation.

[0015] Preferably, the sturdy mounting mechanism further includes a reinforcing plate, which is fixed to the U-shaped support base plate to reinforce the front side of the front side panel a, further improving the load-bearing capacity and deformation resistance of the entire mounting structure, especially when subjected to frontal impact.

[0016] Preferably, the support frame is fixedly disposed on the outer periphery of the support column, providing radial support for the support column. The presence of the support frame effectively prevents the support column from bending or becoming unstable when subjected to large impact forces, thereby ensuring the smoothness and reliability of the sliding seat sliding on it.

[0017] Preferably, the edge of the front side panel a is installed together with the mounting limiting block inside the mounting groove of the U-shaped support base plate. This mating method, through the precise engagement of the mounting limiting block and the mounting groove, achieves reliable positioning and secure installation of the front side panel a, ensuring its stability during vehicle operation.

[0018] The present invention has the following beneficial effects: 1. This invention, by setting up a stable installation mechanism, uses the installation groove on the U-shaped support base plate in conjunction with the installation limiting block to fix the front side panel, and supplements it with support cylinders, reinforcing ribs and reinforcing plates for multiple reinforcements, which solves the problems of unstable installation and poor structural stability of the front side panel in the prior art, and achieves the technical effect of making the installation of the front side panel more secure and stable, and improving the overall structural reliability.

[0019] 2. This invention, by setting up an anti-collision mechanism, transmits force through the support seat, rotating rod, and fixed seat during a collision, driving the sliding seat to slide along the support column, thereby pushing the telescopic spring a in the elastic assembly to slide to both sides and the telescopic spring b to compress in the center. This solves the problems of the existing support device having a simple buffer structure, poor energy absorption effect, and inability to effectively protect the engine area. It achieves the technical effect of efficiently absorbing and dissipating collision energy through the complex compression of the spring assembly, significantly reducing damage to the engine area, and improving the overall vehicle safety and crashworthiness.

[0020] 3. The present invention provides radial support to the support column by setting a support frame on the support column, thereby preventing the support column from becoming unstable and deformed when subjected to the impact force transmitted by the sliding seat. This achieves the technical effect of ensuring the stable sliding of the sliding seat under impact and ensuring the reliable operation of the energy absorption mechanism.

[0021] 4. This invention solves the problem of the lack of direct initial protection for the front side panels in the prior art by installing rubber anti-collision posts on the outside of the front side panels, and achieves the technical effect of providing the first layer of buffer protection for the front side panels themselves, effectively dealing with minor collisions.

[0024] According to Figures 1 to 4 This invention provides a lightweight automotive front side panel anti-collision support device, which aims to solve the problems in the prior art where the buffer energy absorption structure of the automotive front side panel support device is insufficient, leading to easy damage to the engine area 2, and the installation structure has poor stability.

[0025] like Figure 1 As shown, a lightweight automotive front bulkhead side panel anti-collision support device is installed on the rear side of the front bulkhead side panel a1 and located in front of the engine compartment 2. It includes a stable mounting mechanism 4 and an anti-collision mechanism 3. The stable mounting mechanism 4 is used to securely mount the front bulkhead side panel a1, and the anti-collision mechanism 3 is used to absorb impact energy in the event of a collision.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the stable installation mechanism 4 includes a U-shaped support base plate 41 with an installation groove 42. The edge of the front side panel a1 and the installation limiting block 45 are installed together inside the installation groove 42, and the installation limiting block 45 is engaged within the installation groove 42 to jointly fix the front side panel a1. The stable installation mechanism 4 also includes a support column 43 and a reinforcing rib 44. The support column 43 is disposed on the U-shaped support base plate 41, and the reinforcing rib 44 connects the support column 43 and the U-shaped support base plate 41. The support column 43 and the reinforcing rib 44 jointly reinforce the support of the front side panel a1. The stable installation mechanism 4 further includes a reinforcing plate 46, which is fixed to the U-shaped support base plate 41 and used to reinforce the front side of the front side panel a1.

[0027] Reference Figure 1 , Figure 3 and Figure 4The anti-collision mechanism 3 includes a support column 33, on which a sliding seat 34 is slidably connected; the anti-collision mechanism 3 also includes a fixed seat 35, which is fixed to the support column 33; a rotating rod 36 is rotatably connected inside the fixed seat 35, and the rotating rod 36 is rotatably disposed inside the fixed seat 35 via a shaft; one end of the rotating rod 36 is connected to a support seat 37, which abuts against the rear side of the front side panel a1 to receive the collision force transmitted by the front side panel a1; to ensure the stability of the support column 33, a support frame 32 is also provided on the support column 33, which is fixedly disposed on the outer periphery of the support column 33 to provide radial support for the support column 33, so as to ensure the stability of the sliding seat 34 when sliding.

[0028] Furthermore, the anti-collision mechanism 3 also includes a spring assembly 38, which is driven by a sliding seat 34; see reference Figure 3 and Figure 4 The elastic component 38 includes a telescopic spring a381, a support plate 382, ​​and a telescopic spring b383; the support plate 382 provides support for the telescopic spring b383; when the sliding seat 34 slides along the support column 33, the sliding seat 34 pushes the telescopic spring a381 to slide to both sides, while simultaneously causing the telescopic spring b383 to be squeezed in the center, thereby absorbing and dissipating collision energy through the compression deformation of the telescopic spring a381 and the telescopic spring b383.

[0029] As a preliminary buffer, rubber anti-collision posts 31 are installed on the outside of the front side panel a1, which are used to protect the front side panel a1 itself.

[0030] As a preferred embodiment, to provide initial collision buffering, please refer to... Figure 1 A rubber anti-collision post 31 is installed on the outside of the front side panel a1. As the first part to come into contact with the collision, the rubber anti-collision post 31 is used to protect the front side panel a1 itself and absorb the initial impact force.

[0031] As another preferred embodiment, in order to achieve effective transmission of collision force, please refer to... Figure 1 and Figure 3 The support base 37 is fixedly connected to one end of the rotating rod 36 and abuts against the rear side of the front side panel a1. The rotating rod 36 is rotatably mounted inside the fixed base 35 via a shaft. The structure allows the impact force received by the support base 37 to be smoothly transmitted to the fixed base 35 and the support column 33 through the rotating rod 36.

[0032] As another preferred embodiment, to improve the overall structural rigidity of the stable mounting mechanism 4, please refer to... Figure 1 and Figure 2The stabilizing installation mechanism 4 also includes a supporting column 43 and a reinforcing rib 44. The supporting column 43 is vertically arranged on the U-shaped supporting base plate 41, and the reinforcing rib 44 is connected between the side wall of the supporting column 43 and the bottom surface of the U-shaped supporting base plate 41. The two work together to reinforce the support of the front side plate a1.

[0033] As another preferred embodiment, to further improve installation stability, please refer to... Figure 2 The stabilizing installation mechanism 4 also includes a reinforcing plate 46, which is fixed to the U-shaped support base plate 41 and close to the front side of the front side plate a1, and is used to strengthen the front support of the front side plate a1 when it is under force.

[0034] As another preferred embodiment, to ensure the sliding stability of the sliding seat 34 under impact, please refer to... Figure 1 and Figure 3 The support frame 32 is fixedly disposed on the outer periphery of the support column 33 to provide radial support for the support column 33. The support frame 32 can prevent the support column 33 from bending and deforming when subjected to the lateral force transmitted by the sliding seat 34, thereby ensuring the stability of the sliding seat 34 when sliding.

[0035] As another preferred embodiment, please refer to [reference needed] for clarifying the installation and fitting relationships. Figure 2 The edge of the front side panel a1 is installed together with the mounting limit block 45 inside the mounting groove 42 of the U-shaped support base plate 41. The precise fixing and limiting of the front side panel a1 is achieved through the snap-fit ​​cooperation between the mounting limit block 45 and the mounting groove 42.

[0036] The working principle is as follows: First, during installation, the stabilizing installation mechanism 4 provides a stable installation base for the front side panel a1. The U-shaped support base plate 41 serves as the base, and the edge of the front side panel a1 and the installation limiting block 45 are installed together inside the installation groove 42 of the U-shaped support base plate 41, which is fixed by snap-fit. At the same time, the support column 43 is set on the U-shaped support base plate 41, the reinforcing rib 44 is connected between the support column 43 and the U-shaped support base plate 41, and the reinforcing plate 46 is fixed to the U-shaped support base plate 41 and reinforces the front side of the front side panel a1. The three work together to ensure the firmness and stability of the installation of the front side panel a1 and improve the reliability of the overall structure.

[0037] Secondly, when a vehicle collision occurs, the anti-collision mechanism 3 activates to absorb energy. When the collision force acts on the front side panel a1, the rubber anti-collision post 31 installed on its exterior first provides initial cushioning. If the impact force is large, the force is transmitted through the front side panel a1 to the support seat 37 abutting its rear side. The support seat 37 transmits the force to the rotating rod 36, which rotates within the fixed seat 35 via a shaft. Since the fixed seat 35 is fixed to the support post 33, the force ultimately causes the sliding seat 34 to slide along the support post 33. During the sliding process, the support frame 32 is fixedly installed. Radial support is provided on the outer periphery of the support column 33 to ensure the stability of the sliding seat 34 during sliding. When the sliding seat 34 slides, it drives the elastic component 38 to work. Specifically, the sliding seat 34 pushes the telescopic spring a381 to slide to both sides, while the telescopic spring b383 supported by the support plate 382 is squeezed in the center. Through the joint compression deformation of the telescopic spring a381 and the telescopic spring b383, a large amount of collision energy is absorbed and dissipated, thereby reducing the impact force on the rear starting area 2 and improving the overall safety and crashworthiness.
