Description

Technical Field

[0001] This utility model relates to the technical field of car door anti-collision beams, and in particular to a high-strength lightweight car door anti-collision beam. Background Technology

[0002] A door impact beam is a safety device installed inside a car door, primarily used to enhance the door's impact resistance in the event of a collision. It is typically made of high-strength steel or other robust materials and effectively absorbs and disperses collision energy, protecting the safety of the vehicle's occupants.

[0003] For collisions involving the door side, it is especially important to ensure that the door can still open and close normally after the impact. On the one hand, the design of the anti-collision beam needs to reduce the damage to the door structure during an accident to a certain extent. On the other hand, it is also necessary to protect the door locking device so that the door can be opened and closed normally. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that car door locks cannot function properly when subjected to impact.

[0005] To achieve the above objectives, this application proposes a high-strength, lightweight automotive door anti-collision beam, installed near the door and door lock; its structure includes: an anti-collision beam body arranged obliquely along the inside of the door; a first slide rail disposed on the front of the door panel; a slider disposed in the first slide rail; a second slide rail disposed on the side of the door panel and located directly in front of the door lock; an L-shaped protective plate disposed in the second slide rail; a first connecting rod connecting the slider and the anti-collision beam body; and a second connecting rod connecting the slider and the L-shaped protective plate.

[0006] This application discloses a high-strength, lightweight automotive door anti-collision beam. When the door is impacted, the anti-collision beam deforms inward towards the door, thereby driving a slider via a first link, which in turn drives an L-shaped protective plate to move away from the door lock via a second link. This increases the distance between the protective plate and the door lock, providing a buffer space for the door lock while adding a protective plate to prevent the door lock from being damaged by impact. This solves the problem that existing automotive door locks cannot function properly when impacted.

[0007] Furthermore, in order to give the connecting rod a certain degree of rotational freedom at the connection point, the ends of both the first and second connecting rods are provided with connecting tubes and connecting assemblies perpendicular to the rod body; wherein, the connecting assembly includes: two mounting plates arranged symmetrically; a connecting shaft disposed between the two mounting plates, and the connecting tubes are mounted on the connecting shaft.

[0008] Furthermore, in order to ensure that the L-shaped guard accurately protects the door lock, the first end face of the L-shaped guard plate is placed directly in front of the door lock.

[0009] Furthermore, in order to enable the second link to effectively push the L-shaped protective plate, a connecting component is provided on the second end face of the L-shaped protective plate.

[0010] Furthermore, to ensure the smooth movement of the L-shaped protective plate, the L-shaped protective plate is arranged horizontally, and the second slide rail is perpendicular to the L-shaped protective plate.

[0011] Furthermore, in order to ensure that the anti-collision beam body can effectively drive the connecting rod when it is impacted, the first connecting rod and the second connecting rod are respectively set on both sides of the slider.

[0012] The beneficial effects of this application are as follows:

[0013] 1. This application discloses a high-strength, lightweight automotive door anti-collision beam. When the door is impacted, the anti-collision beam body deforms inward towards the door, thereby driving a slider through a first link, which in turn drives an L-shaped protective plate to move away from the door lock through a second link. This increases the distance between the protective plate and the door lock, providing buffer space for the door lock while increasing the protective plate to prevent the door lock from being damaged by impact. This solves the problem that the door lock of the vehicle's middle door cannot function properly when impacted.

[0014] 2. The connecting component provided in this application allows the connecting rod to have a certain degree of rotational freedom at the connection point, which can better adapt to the complex force situation generated during collision and prevent the connecting rod from breaking due to excessive force. At the same time, the design of the connecting shaft also facilitates the installation and disassembly of the components.

[0015] 3. The L-shaped protective plate and the second linkage structure of this application have an included angle, forming a stable triangular structure on the front of the door lock, which further enhances the impact resistance of the protective plate. Attached Figure Description

[0032] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1:

[0034] like Figures 1-3 This illustration depicts a high-strength, lightweight automotive door anti-collision beam. To prevent damage to the door lock from impacts, this embodiment's high-strength, lightweight automotive door anti-collision beam includes an anti-collision beam body 3 arranged obliquely along the interior of the door 1, a first slide rail 4 disposed on the front of the door panel of the door 1, and a slider 5 therein. When the door 1 is impacted, the anti-collision beam body 3 deforms inwards towards the door 1. This deformation is transmitted to the slider 5 via a first connecting rod 8, and the slider 5 slides within the first slide rail 4. Simultaneously, a second connecting rod 9 connects the slider 5 to an L-shaped protective plate 7, which is disposed on the side of the door panel of the door 1 and directly in front of the door lock 2. As the slider 5 moves, the second connecting rod 9 drives the L-shaped protective plate 7 to move away from the door lock 2, thereby increasing the distance between the protective plate 7 and the door lock 2. This design not only provides a buffer space for the door lock 2 but also prevents damage to the door lock 2 from direct impacts through the added protective plate 7, solving the problem in the prior art where door locks fail to function properly when impacted.

[0035] Example 2:

[0036] like Figures 1-2 This illustration depicts a high-strength, lightweight automotive door anti-collision beam according to this application. To adapt to the complex force conditions during a collision, in this embodiment, both the first link 8 and the second link 9 are provided with connecting pipes 10 perpendicular to the link body and connecting assemblies 11. The connecting assembly 11 includes two symmetrically arranged mounting plates 111 and a connecting shaft 112 disposed between the two mounting plates 111, with the connecting pipes 10 mounted on the connecting shaft 112. This design allows the links to have a certain degree of rotational freedom at the connection point, enabling better adaptation to the complex force conditions generated during a collision. When the anti-collision beam body 3 is impacted, the links can disperse and absorb the impact force through the rotation of the connecting assembly 11, preventing the links from breaking due to excessive force.

[0037] Furthermore, by tightening the bolts at the end of the connecting shaft 112, the connecting shaft can be fixed on the mounting plate 111. At the same time, by loosening the bolts, the connecting shaft 112 can be removed from the mounting plate 111, thus separating the connecting assembly 11 from the connecting rod. The design of the connecting shaft 112 also facilitates the installation and disassembly of the components, improving the convenience of maintenance.

[0038] Example 3:

[0039] like Figure 3 This illustration depicts a high-strength, lightweight automotive door anti-collision beam according to this application. To enhance the impact resistance of the protective plate, in this embodiment, the first end face 71 of the L-shaped protective plate 7 is positioned directly in front of the door lock 2, facing any potential impact. A connecting component 11 is also provided on the second end face 72 of the L-shaped protective plate 7 for connection to the second connecting rod 9. This design creates an angle between the L-shaped protective plate 7 and the second connecting rod 9, forming a stable triangular structure on the front of the door lock 2. This triangular structure provides better stability and impact resistance, effectively dispersing and absorbing impact forces during a collision, further protecting the door lock 2 from damage. Simultaneously, the L-shaped protective plate 7 is horizontally arranged, and the second slide rail 6 is perpendicular to the L-shaped protective plate 7, ensuring that the L-shaped protective plate 7 remains stable and smooth during movement.

[0040] Example 4:

[0041] like Figures 1-3 This illustration depicts a high-strength, lightweight automotive door anti-collision beam, designed to effectively drive the linkage and protect the door lock.

[0042] To ensure that the anti-collision beam body 3 can effectively drive the connecting rod and protect the door lock 2 when impacted, in this embodiment, the first connecting rod 8 and the second connecting rod 9 are respectively located on both sides of the slider 5. This design allows the slider 5 to simultaneously drive the first connecting rod 8 and the second connecting rod 9 when pushed by the anti-collision beam body 3, ensuring that the L-shaped protective plate 7 can move quickly and effectively away from the door lock 2. At the same time, since the first connecting rod 8 and the second connecting rod 9 are respectively located on both sides of the slider 5, they form a certain supporting and balancing effect, improving the stability and reliability of the entire anti-collision beam structure.

[0043] Example 5:

[0044] like Figure 1 This illustration depicts a high-strength, lightweight automotive door anti-collision beam according to this application. To achieve a combination of high strength and lightweight design, the anti-collision beam body 3 in this embodiment is made of high-strength lightweight materials such as high-strength steel or aluminum alloy. These materials possess high strength, high toughness, and good fatigue resistance, enabling them to effectively absorb and disperse impact forces during a collision. Simultaneously, these materials also have low density and weight, contributing to reducing the overall weight of the door and improving vehicle fuel economy and driving performance. Therefore, the high-strength, lightweight automotive door anti-collision beam of this embodiment achieves both high-strength impact resistance and lightweight design.
