Currently, my country has introduced a number of regulations on vehicle safety and performance. At the same time, vehicle users are raising their requirements for safety standards, among which the passive safety performance of automobiles has become a focus of widespread social attention. In particular, the front bulkhead of a vehicle is designed to be relatively thin, which makes it impossible to effectively prevent intrusion into the passenger compartment in the event of a collision.
[0003] Chinese patent with authorization announcement number "CN221874164U" discloses a vehicle front bulkhead reinforcement beam structure, including a device body. The device body includes a front bulkhead middle crossbeam, a front bulkhead panel, a front bulkhead upper crossbeam, and a front bulkhead reinforcement beam. The front bulkhead panel has a rectangular structure. The bottom of the front bulkhead reinforcement plate is welded and fixed to the front bulkhead middle crossbeam. The front bulkhead reinforcement beam includes a welded beam and a reinforcing beam. The reinforcing beam is located at the front end of the welded beam. The surface of the reinforcing beam has a crumple zone with a long strip structure. This device can effectively solve the problem of the weak middle part of the front bulkhead panel.
[0004] During later use, the structure still has the following problems: the contact area between the structure and the front bulkhead is limited, and the connection strength needs to be further improved to enhance the structural strength of the front bulkhead. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vehicle front bulkhead reinforcement beam structure. It uses a detachable wire clamp to limit and fix the pipelines passing near the front bulkhead. When it is necessary to inspect the pipelines, the wire clamp can be quickly opened, the position of the wire harness can be adjusted and then fixed again, so as to avoid the pipelines being messy and difficult to maintain later, and to avoid increasing the risk of pipeline damage.
[0006] The aforementioned vehicle front bulkhead reinforcing beam structure includes a base plate, with positioning holes fixedly opened at the front and rear of the base plate, multiple sets of reserved bolt holes fixedly opened in the middle of the base plate, a through hole two fixedly opened at the front of the base plate, an installation hole fixedly opened on one side of the through hole two, a detachable wire clip fixedly connected to the back of the base plate, and flip plates fixedly opened on both sides of the base plate, with a folded edge one and a folded edge two extending outward from the top of the flip plate.
[0007] Preferably, a stepped curved edge is fixedly provided on the flip plate, and a through hole is fixedly provided on the stepped curved edge.
[0008] Preferably, multiple sets of protruding plates are fixedly provided on the first folded edge, and an avoidance notch is fixedly opened on the outer side of the first folded edge.
[0009] Preferably, the second folded edge includes a first edge, two edges are fixedly provided at the rear of the first edge, and three edges are fixedly provided at the rear of the two edges.
[0010] Preferably, the detachable cable clip includes a cable clip body, a hinge mechanism fixedly connected to the right side of the cable clip body, a buckle mechanism fixedly provided on the left side of the cable clip body, and an inclined plate fixedly connected to the bottom of the cable clip body. The bottom of the inclined plate has a limit hole and a fixing hole, and a metal bushing is fixedly installed in the fixing hole.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. By setting detachable cable clips, the pipelines passing near the front panel are limited and fixed. When it is necessary to inspect the pipelines, the cable clips can be quickly opened, the position of the cable harness can be adjusted and then fixed again, so as to avoid the pipelines being messy and difficult to maintain later, and to avoid increasing the risk of pipeline damage.
[0013] 2. By setting fold one and fold two, the contact area between the reinforcing beam and the front bulkhead is increased, and the welding connection strength between the two is improved. When the vehicle collides, the reinforcing beam can provide more support for the front bulkhead, thereby improving passive safety performance. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] like Figure 1 and Figure 2 As shown, a vehicle front bulkhead reinforcement beam structure includes a base plate 8. Positioning holes 3 are fixedly provided at both the front and rear of the base plate 8. These positioning holes 3 improve the accuracy of the reinforcement beam installation on the front bulkhead and ensure installation quality. Multiple sets of pre-drilled bolt holes 4 are fixedly provided in the middle of the base plate 8. A second through hole 5 is also fixedly provided at the front of the base plate 8. An installation hole 6 is fixedly provided on one side of the second through hole 5. A detachable wire clip 7 is fixedly connected to the back of the base plate 8. By setting the detachable wire clip 7, pipelines passing near the front bulkhead are limited and fixed. When pipeline maintenance is required, the wire clip can be quickly opened, the position of the wiring harness adjusted, and then fixed again, preventing messy pipelines from causing difficulties in later maintenance and increasing the risk of pipeline damage.
[0023] Both sides of the base plate 8 are fixedly equipped with flaps 1, and the top of the flaps 1 extends outward with folded edges 2, which include folded edge one 201 and folded edge two 202. By setting folded edge one 201 and folded edge two 202, the contact area between the reinforcing beam and the front bulkhead is increased, and the welding connection strength between the two is improved. When the vehicle collides, the reinforcing beam can provide more support for the front bulkhead, thereby improving passive safety performance.
[0024] like Figure 3 As shown, a stepped bend 102 is fixedly provided on the flap 1. By setting the stepped bend 102 structure on the flap 1, the structural strength of the flap 1 can be increased and the support force on the front panel can be improved. A through hole 101 is fixedly opened on the stepped bend 102. By setting the through hole 101, the cable tie can be passed through the through hole 101 to bind and limit the part of the pipeline passing near the front panel.
[0025] Multiple sets of protruding plates 201B are fixedly provided on the flange 201. The design of multiple sets of protruding plates 201B can increase the structural strength of the flange 201. An avoidance notch 201A is fixedly opened on the outer side of the flange 201. By opening the avoidance notch 201A, the process holes on the front panel are avoided, thus preventing structural interference.
[0026] Folded edge 202 includes a first edge 202A, a second edge 202B fixedly provided at the rear of the first edge 202A, and a third edge 202C fixedly provided at the rear of the second edge 202B. By setting the first edge 202A, the second edge 202B, and the third edge 202C, it can be ensured that folded edge 202 is fully fitted with the front panel, leaving sufficient welding area and improving the connection strength between the two.
[0027] like Figure 4 and Figure 5 As shown, the detachable cable clamp 7 includes a cable clamp body 701. A hinge mechanism 704 is fixedly connected to the right side of the cable clamp body 701. The hinge structure is made of PA66 material and is used to connect the upper and lower parts of the cable clamp body 701. Opening the latching mechanism 703 opens the cable clamp body 701, allowing the wire harness that needs to be limited to be placed inside. Closing the latching mechanism 703 then allows the detachable cable clamp 7 to be used for limiting the installation of pipes, air conditioning pipes, DC-DC converters, and other wire harnesses that pass through this location. A buckle mechanism 703 is fixedly provided on the left side of the cable clip body 701. An inclined plate 702 is fixedly connected to the bottom of the cable clip body 701. A limit hole 705 and a fixing hole 706 are provided at the bottom of the inclined plate 702. The limit hole 705 is screwed to the mounting hole 6 by an M6 bolt. A metal bushing 707 is fixedly installed in the fixing hole 706. By fixing the metal bushing 707 in the fixing hole 706, the structural strength of the cable clip fixing hole 706 is improved. The bolt is used to connect it to the through hole 5 to solve the risk of fixing failure.
[0028] This utility model uses a detachable cable clamp 7 to limit and fix pipelines passing near the front bulkhead. When pipeline maintenance is required, the cable clamp can be quickly opened, the position of the cable harness adjusted, and then fixed again, avoiding messy pipelines that would make later maintenance difficult and increasing the risk of pipeline damage. By setting folded edge one 201 and folded edge two 202, the contact area between the reinforcing beam and the front bulkhead is increased, improving the welding connection strength between the two. When a vehicle collision occurs, the reinforcing beam can provide more support to the front bulkhead, improving passive safety performance.
