[0004] The existing anti-collision beam structure of general VAN vehicles mainly consists of the upper anti-collision beam of the front door and the lower anti-collision beam of the front door, which are relatively independent and unrelated. Figure 5 As shown: Mark 1 is the upper anti-collision beam of the front door, and mark 2 is the lower anti-collision beam of the front door. Figure 6 As shown: Mark 1 is the front door upper anti-collision beam, mark 2 is the front door lower anti-collision beam, and mark 6 is the collision block of the GB20071-202X mobile deformable barrier. Due to the special structural arrangement of the VAN car, the impactor of the side collision regulations only directly collides with the front door lower anti-collision beam, and does not directly collide with the front door upper anti-collision beam, so the front door upper anti-collision beam cannot effectively absorb the collision energy. Summary of the invention

[0038] Combination Figure 1-3 As shown, the present invention provides a front door anti-collision beam structure for a VAN vehicle, comprising: an upper anti-collision beam 1, a lower anti-collision beam 2 and at least one connecting plate 4, the upper anti-collision beam 1 is connected above the front door outer panel 3 of the VAN vehicle; the lower anti-collision beam 2 is connected below the front door outer panel 3 of the VAN vehicle; the connecting plate 4 is connected to the front door outer panel 3 of the VAN vehicle, and the two ends of the connecting plate 4 are respectively connected to the upper anti-collision beam 1 and the lower anti-collision beam 2.
[0039] In the embodiment of the present invention, combined with Figure 5-6 As shown, a VAN vehicle refers to a van or a small passenger and freight vehicle. Unlike a common car, a VAN vehicle has a higher front door. The impactor of the existing VAN vehicle side collision regulations can only directly collide with the lower anti-collision beam 2 of the VAN vehicle front door. Moreover, when some car accidents occur, the upper anti-collision beam 1 of the VAN vehicle front door is not directly collided, resulting in the upper anti-collision beam 1 of the front door being unable to effectively absorb the collision energy. The upper anti-collision beam 1 and the lower anti-collision beam 2 are respectively connected by connecting the two ends of the connecting plate 4, so that when the impactor of the VAN vehicle side collision regulations collides with the lower anti-collision beam 2 of the VAN vehicle front door, the impact force received by the lower anti-collision beam 2 is transmitted to the upper anti-collision beam 1 through the connecting plate 4, so that the upper anti-collision beam 1 can play a role in absorbing the collision energy, reducing the impact force received by the front door of the VAN vehicle, thereby ensuring the safety of the VAN vehicle and personnel.
[0040] In some embodiments, the connecting plate 4 is welded to the upper anti-collision beam 1 .
[0041] In this embodiment, the welding connection enables the connection between the connecting plate 4 and the upper anti-collision beam 1 to be tightly connected, and the welding connection has low cost and a stable connection.
[0042] In some embodiments, the connecting plate 4 is connected to the lower anti-collision beam 2 by welding.
[0043] In this embodiment, the welding connection enables the connection between the connecting plate 4 and the lower anti-collision beam 2 to be tight, and the welding connection has low cost and a stable connection.
[0044] In some embodiments, the connecting plate 4 is connected to the front door outer panel 3 via a seismic isolation adhesive 5 .
[0045] In this embodiment, the seismic isolation rubber 5 can reduce the vibration of the front door outer panel 3 when it is hit, thereby playing a certain protective role on the front door outer panel 3 and reducing the harm of the impact to the VAN vehicle and personnel.
[0046] In some embodiments, connecting parts 41 are provided on both sides of the connecting plate 4 , and the connecting parts 41 are connected to the front door outer panel 3 via a seismic isolation adhesive 5 .
[0047] In this embodiment, connecting parts 41 are provided on both sides of the connecting plate 4 so that the connection between the connecting plate 4 and the front door outer panel 3 is more stable, and both sides are connected by the seismic isolation glue 5 so that the shock absorption effect of the seismic isolation glue 5 is better.
[0048] In some embodiments, a shock absorbing chamber 42 is provided between the connecting plate 4 and the front door outer panel 3 .
[0049] In this embodiment, the shock absorbing chamber 42 can not only reduce the vibration of the front door outer panel 3 when it is hit, but also provide a certain buffer space for the deformation of the front door outer panel 3 when the impact is severe, thereby playing a certain protective role for the front door outer panel 3 and reducing the harm of the impact to the VAN vehicle and personnel.
[0050] In some embodiments, the interval between the upper anti-collision beam 1 and the lower anti-collision beam 2 gradually increases from an end close to the front of the VAN vehicle to an end away from the front of the VAN vehicle.
[0051] In this embodiment, the interval between the upper anti-collision beam 1 and the lower anti-collision beam 2 gradually increases from the end close to the front of the VAN car to the end away from the front of the VAN car according to the structural design of the front door outer panel 3, so that when the front door of the VAN car is hit, the upper anti-collision beam 1 and the lower anti-collision beam 2 can better share the impact force. Specifically, the upper anti-collision beam 1 is parallel to the horizontal ground, and the lower anti-collision beam 2 is inclined, so that the upper anti-collision beam 1 can withstand a larger impact force, and the lower anti-collision beam 2 can accept impact forces from more directions.
[0052] In some embodiments, the connecting plate 4 is connected to an end of the upper anti-collision beam 1 and the lower anti-collision beam 2 away from the front end of the VAN vehicle.
[0053] In this embodiment, the connecting plate 4 is connected to the upper anti-collision beam 1 and the lower anti-collision beam 2 at one end away from the front of the VAN vehicle, so that the upper anti-collision beam 1, the lower anti-collision beam 2 and the connecting plate 4 form a triangular structure, which makes the front door anti-collision beam structure as a whole more stable and facilitates the transmission of the impact force received by the lower anti-collision beam 2 to the upper anti-collision beam 1.
[0054] The present invention further provides a VAN vehicle, comprising a VAN vehicle body (not shown) and the above front door anti-collision beam structure for the VAN vehicle, wherein the front door anti-collision beam structure is connected to the VAN vehicle body.
[0055] In the embodiment of the present invention, the VAN car uses the above-mentioned front door anti-collision beam structure, and the upper anti-collision beam 1 and the lower anti-collision beam 2 are respectively connected by the two ends of the connecting plate 4, so that when the impactor of the VAN car side collision regulations collides with the lower anti-collision beam 2 of the front door of the VAN car, the impact force received by the lower anti-collision beam 2 is transmitted to the upper anti-collision beam 1 through the connecting plate 4, so that the upper anti-collision beam 1 can play a role in absorbing the collision energy, reducing the impact force received by the front door of the VAN car, thereby ensuring the safety of the VAN car and personnel.
[0056] Combination Figure 4 As shown, the present invention also provides a method for installing a front door anti-collision beam structure for a VAN vehicle, comprising steps S10 to S30:
[0057] S10, welding the upper anti-collision beam 1 above the front door outer panel 3 of the VAN vehicle;
[0058] S20, welding the lower anti-collision beam 2 to the lower part of the front door outer panel 3 of the VAN vehicle;
[0059] S30, connecting at least one connecting plate 4 to the front door outer panel 3 of the VAN vehicle, and connecting the two ends of the connecting plate 4 to the upper anti-collision beam 1 and the lower anti-collision beam 2 respectively.
[0060] In the embodiment of the present invention, the upper anti-collision beam 1 and the lower anti-collision beam 2 are respectively welded and connected by the two ends of the connecting plate 4. The welding connection cost is low and the connection is stable. When the impactor of the VAN vehicle side collision regulations collides with the lower anti-collision beam 2 of the VAN vehicle front door, the impact force received by the lower anti-collision beam 2 is transmitted to the upper anti-collision beam 1 through the connecting plate 4, so that the upper anti-collision beam 1 can play a role in absorbing the collision energy, reducing the impact force received by the front door of the VAN vehicle, thereby ensuring the safety of the VAN vehicle and personnel.
[0061] It can be understood that steps S10 to S30 are performed in no particular order.
[0062] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
