Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision vehicles, in particular to an anti-collision structure for a van-type vehicle. Background Art

[0002] In the prior art, when an emergency occurs on a highway, such as a car accident, road damage, etc., vehicles and personnel are required for maintenance. In the prior maintenance process, special vehicles are mostly used to be placed behind the work area for warning. However, this method has a low safety factor and cannot ensure safety well. Therefore, most vans will be equipped with a collision-proof buffer structure (collision-proof bag, collision-proof cushion, etc.) at the rear, such as a road construction collision-proof vehicle proposed in Publication No. CN218877143U; However, this type of collision-proof vehicle still has the following problems when used:

[0003] For vehicles with low chassis, such as sedans, their anti-collision and arresting performance is poor. Vehicles with low chassis are very likely to drill under the car after a collision, posing a major safety hazard. Utility Model Content

[0004] In view of this, the problem to be solved by the utility model is to provide an anti-collision structure for a van.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A box car anti-collision structure comprises an anti-collision buffer component, wherein the anti-collision buffer component is connected to a main beam of a car body through a blocking component.

[0007] The portion of the blocking member connected to the main beam is also connected to at least one group of secondary beams and / or one group of cross beams.

[0008] The blocking member is an L-shaped angle steel structure, and the blocking member is symmetrically installed on both sides of the main beam.

[0009] A carriage extension portion is arranged above the anti-collision buffer member;

[0010] The side end and the bottom end of the side panel mounting frame of the extended part of the carriage are respectively connected to the pillar of the carriage and the upper cover plate of the anti-collision buffer member;

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] like Figure 1 to Figure 2 As shown, the utility model provides an anti-collision structure for a van, including an anti-collision buffer 1, which is connected to the main beam 31 of the vehicle body through a blocking member 2; when the vehicle encounters a rear impact, the anti-collision buffer 1 plays a buffering and energy release role to reduce casualties and property losses of the rear vehicle, and the blocking member 2 can block vehicles with lower chassis such as cars from continuing to move forward, avoiding drilling into the bottom of the vehicle after the impact.

[0036] Furthermore, in order to improve the connection stability of the blocking member 2 and the force distribution when it is impacted, in this embodiment, the portion of the blocking member 2 connected to the main beam 31 is also connected to at least one group of secondary beams 32 and / or a group of cross beams.

[0037] Specifically, in the present embodiment, the blocking member 2 is an L-shaped angle steel structure, and the blocking member 2 is symmetrically installed on both sides of the main beam 31. When impacted, the main beam 31 is evenly stressed. Through holes are opened on the main beam 31 and the secondary beam 32 and / or the cross beam, and are connected and fixed to the blocking member 2 by a bolt assembly. The other side of the blocking member 2 is connected and fixed to the anti-collision buffer member 1 by a bolt assembly.

[0038] Furthermore, in this embodiment, the space above the anti-collision buffer member 1 can be reasonably utilized without changing the length of the original anti-collision buffer vehicle, thereby extending the vehicle compartment;

[0039] Specifically, a compartment extension portion 4 is provided above the anti-collision buffer member 1 , and after extension, the storage space can be increased by about 20% on the original basis.

[0040] Furthermore, considering that the general truck compartments are made and fixed by bending and welding steel plates, if the extended part is fixed by bending and welding steel plates, when a rear vehicle collides, the steel plate may splash and hit or penetrate the rear vehicle, causing casualties;

[0041] like Figures 3 to 5 As shown, in this embodiment, the side panels 51, rear sealing panel 52, and bottom panel 53 of the car body extension 4 are all made of aluminum honeycomb panel structures, and the corresponding side panel mounting frames 41, rear sealing panel mounting frames 42, and side panel mounting frames 41 are also made of lightweight aluminum materials. When hit by a rear vehicle, the side panels 51, rear sealing panel 52, and bottom panel 5 of the honeycomb aluminum panel structure can play a role in buffering and releasing energy;

[0042] The specific connection method is as follows: the side end and the bottom end of the side panel mounting frame 41 of the car extension 4 are respectively connected to the column 91 of the car and the upper cover plate 11 of the anti-collision buffer 1; the side end and the bottom end of the rear cover plate mounting frame 42 of the car extension 4 are respectively connected to the side panel mounting frame 41 and the upper cover plate 11; the side end of the bottom plate mounting frame 43 of the car extension 4 is connected to the side panel mounting frame 41; the side panel mounting frame 41, the rear cover plate mounting frame 42, and the side panel mounting frame 41 are all configured with mounting slots 6 for correspondingly plugging in the side panels 51, the rear cover plate 52, and the bottom plate 53, and in addition, all components of the car extension 4 are also configured with openings for connection and fixing by bolt assemblies after plugging;

[0043] The design of the honeycomb aluminum plate and the aluminum frame of the vehicle compartment extension 4 makes it easy for the vehicle to disintegrate after a strong collision, playing a secondary buffering and energy release role, further improving the protection.

[0044] Moreover, the prior art (such as publication number CN218877143U) relies on a flipping device to connect the anti-collision buffer. If the anti-collision buffer is flipped and unfolded during driving, the problem of vehicle length exceeding the limit will occur. Therefore, the anti-collision effect can only be achieved after the anti-collision buffer is flipped and unfolded after the vehicle stops. In the present technical solution, the combined anti-collision structure composed of the anti-collision buffer 1 and the car body extension 4 is always fixed on the rear side of the vehicle body, which can provide real-time protection for the vehicle body.

[0045] like Figure 6 to Figure 7 As shown, further, in order to increase the connection stability between the anti-collision buffer 1 and the car body and enable it to better play the primary buffering energy release role, in this embodiment, the anti-collision buffer 1 is connected to the blocking member 2 through an anti-collision mounting frame 16, and the two sides of the anti-collision mounting frame 16 are connected to the car body through a right-angle frame 12; so that the middle and both sides of the anti-collision buffer 1 are supported by the connecting structure.

[0046] Furthermore, in this embodiment, in order to improve the overall appearance and protection safety, the bottom of the car body is fully surrounded;

[0047] Specifically, a transverse decorative panel 13 is connected to the right-angle frame 12, and the transverse decorative panel 13 is arranged along the length direction of the car body. A vertical decorative panel 14 is also installed on the side panel 51 of the car body extension part 4 and the side end of the anti-collision buffer 1, and the vertical decorative panel 14 is at the same height as the bottom of the anti-collision buffer 1; on the one hand, decorative covers can be added to the connection parts between the anti-collision buffer 1 and the blocking member 2 and the car body, as well as the exposed wiring, to make the appearance beautiful, and on the other hand, in the event of a collision, some flying objects can be blocked to avoid hitting the car and injuring people.

[0048] Specifically, a tool box is installed at the bottom of the carriage, and a movable door 15 adapted to the tool box is correspondingly arranged on the transverse decorative panel 13 .

[0049] The working principle and working process of the utility model are as follows:

[0050] When the vehicle encounters a rear impact, the anti-collision buffer 1 plays a primary buffering and energy release role. If the impact is more severe, the design of the honeycomb aluminum plate and the aluminum frame of the car body extension 4 makes the vehicle easy to disintegrate after a strong collision, playing a secondary buffering and energy release role, further improving the protection. The blocking member 2 can block vehicles with lower chassis such as sedans from continuing to move forward, avoiding drilling into the bottom of the car body after the collision, reducing casualties and property losses of the rear vehicles. The horizontal decorative panel 13 and the vertical decorative panel 14 can block some flying objects to avoid hitting the car and injuring people.

[0051] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
