Description

Technical Field

[0001] This utility model belongs to the field of automotive body technology, and more specifically, it relates to a longitudinal beam reinforcement structure for automotive bodies. Background Technology

[0002] The longitudinal beams of the vehicle body are the main reinforcing structural components of the passenger compartment in the direction of vehicle travel. With the continuous increase in the weight of automobiles and the increasing requirements of users for passive safety, higher requirements are placed on the bending stiffness and torsional stiffness of the longitudinal beams of the vehicle body.

[0003] Chinese patent with authorization announcement number "CN202624372U" discloses a longitudinal beam reinforcement structure for automobiles, which overcomes the problem that the front end formed by the longitudinal beam and the longitudinal beam reinforcement plate in the prior art is too rigid, causing it to generate a huge impact force at the moment of collision. The structure includes a longitudinal beam connecting plate, a longitudinal beam reinforcement plate and a longitudinal beam outer plate. The longitudinal beam reinforcement plate has a U-shaped structure, and one end of the longitudinal beam reinforcement plate is fixedly connected to the longitudinal beam connecting plate.

[0004] During later use, the structure still has the following problems: the connection area between the structure and the longitudinal beam of the vehicle body is insufficient, resulting in low connection strength between the two, and it is impossible to strengthen the connection nodes between the longitudinal beam of the vehicle body and other structures. 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 body longitudinal beam reinforcement beam structure, which constrains the guidance of cables or pipes by setting wire clamps, and tightens them by the cooperation of silicone sheaths and cable ties, thereby improving the compatibility of wire clamps with cables or pipes of different diameters and simplifying the wiring layout.

[0006] The aforementioned vehicle body longitudinal beam reinforcement beam structure includes a base plate. The front and rear of the base plate are both fixedly provided with wire clamp mounting holes. Wire clamps are installed in the wire clamp mounting holes, which include wire clamp limiting openings and wire clamp fixing openings. A reserved through hole four is also fixedly provided at the front of the base plate. A ground limiting opening is fixedly provided on one side of the reserved through hole four, and a ground fixing hole is fixedly provided on one side of the ground limiting opening. A reserved through hole two is fixedly provided in the middle of the base plate, and a reserved through hole three is fixedly provided at the rear of the base plate. A subframe fixing through hole is fixedly provided on one side of the reserved through hole three. Side plates are fixedly connected to both sides of the base plate. A process positioning hole one, a connector locking hole two, and a reserved through hole one are fixedly provided on the side plates.

[0007] Preferably, the bottom plate has a flange extending downward at the front, a flange extending outward at the front of the side plate, a clearance notch fixedly provided on flange two, a flange extending outward at the top of the side plate, a flange extending outward at the top of the side plate, and a flange extending outward at the rear of the side plate. Multiple sets of protrusions are fixedly provided on flange one and flange three.

[0008] Preferably, a rib groove is fixedly provided on the side plate, and a connector lock-type fixing hole is fixedly opened on the rib groove.

[0009] Preferably, the inner wall of the wire clamp is fixedly provided with a silicone sheath, the wire clamp is provided with a cable tie, the side wall of the wire clamp extends outward with a folded edge, multiple sets of through holes are fixedly opened on the wire clamp, one end of the wire clamp is fixedly opened with an installation port, the installation port is fixedly connected to the wire clamp fixing port by bolts, and a limit block is fixedly connected to the outside of the installation port.

[0010] Preferably, the silicone sheath has an opening on its sidewall.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting wire clamps, the guidance of cables or conduits is constrained. The combination of silicone sleeves and cable ties tightens the clamps, improving their compatibility with cables or conduits of different diameters and simplifying the wiring layout.

[0013] 2. By setting flange one and flange two, the contact area between this reinforcing beam structure and the inner sill plate is increased, and the connection strength between the two is strengthened. By setting flange three, the contact area between this reinforcing beam structure and the vehicle floor is increased. By setting flange four, the contact area between this reinforcing beam structure and the vehicle longitudinal beam is increased, and the connection strength between this reinforcing beam and the vehicle floor and vehicle longitudinal beam is strengthened. By setting multiple sets of protrusions on flange one and flange three, the structural strength of flange one and flange two themselves is increased. 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 body longitudinal beam reinforcement beam structure includes a base plate 1. Both the front and rear of the base plate 1 are fixedly provided with wire clamp mounting holes 3. Wire clamps 12 are installed in the wire clamp mounting holes 3. By setting the wire clamps 12, the guidance of cables or conduits is constrained. The wire clamps are tightened by the cooperation of silicone sleeves 14 and cable ties 13, improving the compatibility of the wire clamps 12 with cables or conduits of different diameters and simplifying the wiring layout. The wire clamp mounting holes 3 include wire clamp limiting ports 301 and wire clamp fixing ports 302. Multiple wire clamp mounting holes 3 are arranged on this reinforcement beam structure to facilitate the installation of more wire clamps 12 for guiding the wiring, etc. A reserved through hole four 15 is also fixedly provided at the front of the base plate 1. By setting multiple sets of reserved through holes, a path is provided for wire harnesses, conduits, etc., to pass through the longitudinal beam and reinforcement beam.

[0023] A grounding limiting port 8 is fixedly provided on one side of the reserved through hole 4 15, and a grounding fixing hole 7 is fixedly provided on one side of the grounding limiting port 8. By setting the grounding limiting port 8, the stability of the connection between the grounding terminal and the vehicle body is improved. A reserved through hole 2 9 is fixedly opened in the middle of the base plate 1, and a reserved through hole 3 11 is fixedly opened at the rear of the base plate 1. A subframe fixing through hole 10 is fixedly provided on one side of the reserved through hole 3 11. Side plates 2 are fixedly connected to both sides of the base plate 1. A process positioning hole 1 4 is fixedly opened on the side plate 2. By setting the process positioning hole, it is convenient to accurately position and install the reinforcing beam and other nearby vehicle body structural parts. A connector locking fixing hole 2 5 and a reserved through hole 1 6 are used to fix the connector with a buckle by setting the connector locking fixing hole 204A and the connector locking fixing hole 2 5.

[0024] The bottom plate 1 has a flange 101 extending downward from the front, and the side plate 2 has a flange 201 extending outward from the front. A clearance notch 201A is fixedly provided on the flange 201. By providing the clearance notch 201A, the process holes on the inner panel of the door frame can be avoided, thus avoiding structural interference. The top of the side plate 2 has a flange 302 extending outward, and the rear of the side plate 2 has a flange 403 extending outward. Multiple sets of protrusions are fixedly provided on both flange 101 and flange 302. By setting flange one 101 and flange two 201, the contact area between this reinforcing beam structure and the inner sill plate is increased, and the connection strength between the two is strengthened. By setting flange three 202, the contact area between this reinforcing beam structure and the vehicle floor is increased. By setting flange four 203, the contact area between this reinforcing beam structure and the vehicle longitudinal beam is increased, and the connection strength between this reinforcing beam and the vehicle floor and the vehicle longitudinal beam is strengthened. By setting multiple sets of protrusions on flange one 101 and flange three 202, the structural strength of flange one 101 and flange two 201 themselves is increased.

[0025] A rib groove 204 is fixedly provided on the side plate 2, and a connector lock-type fixing hole 204A is fixedly opened on the rib groove 204. By setting the rib groove 204, the structural strength of the side plate 2 is improved. When the vehicle body is involved in a collision, this reinforcing beam structure can provide higher support strength to the longitudinal beam of the vehicle body, thereby improving the passive safety performance of the vehicle.

[0026] like Figure 3 and Figure 4As shown, a silicone sleeve 14 is fixedly provided on the inner wall of the wire clamp 12, and a cable tie 13 is provided on the wire clamp 12. The silicone sleeve 14 is placed on the pipeline that needs to be guided and limited, and the cable tie 13 is passed through the through hole 1201 to firmly fix the silicone sleeve 14 to the wire clamp 12. Through the cooperation of the silicone sleeve 14 and the cable tie 13, cables or pipelines of different sizes can be accommodated and their positions can be limited by the wire clamp 12. This avoids messy cable layout inside the vehicle body, which not only easily causes safety hazards and increases the maintenance difficulty for after-sales personnel, but is also not aesthetically pleasing and simple. The side wall of the wire clamp 12 extends outward with a folded edge 1204. By setting the folded edge 1204, it is extremely easy to The structural strength of the wire clamp 12 body is greatly increased. Multiple sets of through holes 1201 are fixedly opened on the wire clamp 12. The through holes 1201 cooperate with the cable tie 13 to bind the wire harness. One end of the wire clamp 12 is fixedly opened with an installation port 1202. The installation port 1202 is fixedly connected to the wire clamp fixing port 302 by bolts. A limiting block 1203 is fixedly connected to the outside of the installation port 1202. The limiting block 1203 cooperates with the wire clamp limiting port 301 to ensure the connection strength between the wire clamp 12 and the reinforcing beam. When the wire clamp 12 guides the wire harness, the wire clamp 12 itself can be firmly fixed in the current position to prevent the wire clamp 12 from deflecting.

[0027] like Figure 5 As shown, the silicone sleeve 14 has an opening 1401 on its side wall. In use, the silicone sleeve 14 is opened through the opening 1401 and placed over the pipeline to be secured. Then, the cable tie 13 is used to secure it to the wire clamp 12, thus completing the fixation of the wire harness. Wire harnesses passing through this area typically include charging dock power harnesses, power battery output harnesses, motor DC busbars, etc.

[0028] This utility model constrains the guidance of cables or pipes by setting a wire clamp 12, and tightens it by cooperating with a silicone sheath 14 and a cable tie 13, thereby improving the compatibility of the wire clamp 12 with cables or pipes of different diameters and simplifying the wiring layout. By setting flange one 101 and flange two 201, the contact area between the reinforcing beam structure and the inner door sill plate is increased, and the connection strength between the two is strengthened. By setting flange three 202, the contact area between the reinforcing beam structure and the vehicle floor is increased. By setting flange four 203, the contact area between the reinforcing beam structure and the vehicle longitudinal beam is increased, and the connection strength between the reinforcing beam and the vehicle floor and the vehicle longitudinal beam is strengthened. By setting multiple sets of protrusions on flange one 101 and flange three 202, the structural strength of flange one 101 and flange two 201 themselves is increased.
