[0002] The guide is usually installed at both ends of the anti-collision beam and plays an important role in vehicle collision handling. When the anti-collision beam is stressed and bent, the guide deforms and acts on the front longitudinal beam that supports the anti-collision beam, so as to apply a thrust to the front longitudinal beam, and then guide the vehicle body to move along the stress direction, realizing the offset guidance of the vehicle body and effectively improving the safety performance of the vehicle.

[0003] However, the existing guide lacks the function of fixing the front cabin wire harness, resulting in that the front cabin wire harness needs to be equipped with an additional fixing structure to be fixed on the anti-collision beam to realize the connection with the front bumper wire harness. This method increases the production cost and is likely to damage the front cabin wire harness when the anti-collision beam is stressed and bent, thus causing potential safety hazards.

[0031] Embodiment 1

[0032] Referring to Figures 1-6 As shown, this embodiment discloses a guide member with a function of fixing a wire harness, including a guide member body 10.

[0033] Figure 1 This is a schematic diagram of the application scenario of the guide member with a function of fixing a wire harness in this embodiment. The guide member body 10 of this embodiment is applied to Figure 1 the anti-collision beam 20 shown.

[0034] Specifically, the guide member body 10 is provided with a mounting portion 11 and a fixing portion 12; the mounting portion 11 is used to connect the anti-collision beam 20, and the fixing portion 12 is used to connect the wire harness 40.

[0035] The fixing portion 12 of this embodiment is used to fix the front cabin wire harness. During specific implementation, first, the guide member body 10 is installed at the end of the anti-collision beam 20 through the mounting portion 11, then the front cabin wire harness is fixed on the fixing portion 12, and then the front bumper wire harness is docked with the front cabin wire harness, thus realizing the installation of the guide member body 10 and the stable connection of the wire harness 40. In other embodiments, the fixing portion 12 can fix the front bumper wire harness or other wire harnesses 40 according to actual needs.

[0036] The guide member with a function of fixing a wire harness in this embodiment provides a connection structure for fixing the wire harness 40 by arranging the fixing portion 12 on the guide member body 10, improves the utilization rate of the guide member, can not only realize the collision offset of the vehicle, but also realize the fixing of the wire harness 40, so that the guide member has a high function integration, does not need to set an additional fixing structure to fix the wire harness 40, saves the production cost, and simplifies the layout of the anti-collision structure, which is beneficial to the installation and maintenance of the vehicle; the arrangement of the fixing portion 12 enables the wire harness 40 to move along with the guide member, avoids the anti-collision beam 20 from crushing or the collision object from piercing the wire harness 40, greatly reduces the risk of vehicle failure, and improves the reliability and safety of the vehicle.

[0037] Specifically, the fixing portion 12 is provided with a connection hole 121 for clamping or screwing the plug connector of the wire harness. By fixing the plug connector 41 of the wire harness 40, the connection stability of the two butt-jointed wire harnesses 40 is improved, and the plug connector 41 of the wire harness 40 is prevented from swaying or even hitting the anti-collision beam 20 during vehicle driving or collision, which may cause the plug connector 41 to break from the wire harness 40 body and the separation of the two wire harnesses 40. The connection hole 121 provides a convenient fixing space for the plug connector 41, which helps the plug connector 41 of the wire harness 40 to be connected to the fixing portion 12 by clamping or screwing, reduces the installation difficulty of the wire harness 40, and to a certain extent, improves the manufacturing and maintenance efficiency of the vehicle.

[0038] Specifically, the fixing portion 12 includes a support block 122 and a connecting ear 123; the support block 122 is fixedly connected to the mounting portion 11, and the connecting ear 123 extends from the support block 122 along the length direction of the mounting portion 11; the connection hole 121 penetrates through the connecting ear 123. In a specific implementation, the length direction of the mounting portion 11 is consistent with the extending direction of the anti-collision beam 20, and the connecting ear 123 is arranged along the extending direction of the anti-collision beam 20, which is convenient for guiding the front cabin wire harness to extend towards the end of the anti-collision beam 20, promotes the convenient butt-joint of the front cabin wire harness and the front bumper wire harness, and ensures the stability of the connection between the front cabin wire harness and the front bumper wire harness. The setting of the support block 122 forms a certain distance between the connecting ear 123 and the mounting portion 11, which is convenient for the installation and disassembly of the plug connector 41 of the wire harness 40; and the support block 122 protrudes from the mounting portion 11 and has a buffering effect, which can contact the front longitudinal beam 30 in advance during the vehicle's response to collision offset, effectively reducing the direct impact force of the anti-collision beam 20 on the front longitudinal beam 30, reducing the collision damage, and at the same time providing an offset guiding force for the front longitudinal beam 30 to ensure the safety of the vehicle and passengers.

[0039] Specifically, the end of the connecting ear 123 away from the support block 122 is arc-shaped. The arc-shaped setting can prevent the surface of the connecting ear 123 from being flat and breaking or damaging the plug connector 41 of the wire harness 40.

[0040] Specifically, the number of the connecting ears 123 is two, and there is a gap between the two connecting ears 123. The connection hole 121 corresponds to the connecting ear 123. The setting of the two connecting ears 123 increases the fixing stability of the wire harness 40. The plug connectors 41 of the front cabin wire harness are usually two. In a specific implementation, bolts or buckles are pre-set on the two plug connectors 41 so that the two connecting ears 123 correspond to the two plug connectors 41 to fix the two plug connectors respectively, ensuring the connection stability of the plug connector 41 of the wire harness 40. At the same time, the distance between the two connecting ears 123 reduces the rigidity of the fixing portion 12, preventing the fixing portion 12 from bending and breaking during the response to collision, and ensuring the integrity of the guide member body 10 and the wire harness 40.

[0041] Specifically, a first weight-reducing hole 1112 is provided on the support block 122, and the first weight-reducing hole 1112 vertically penetrates through the support block 122. The first weight-reducing hole 1112 effectively reduces the overall weight of the guide member body 10 and provides an elastic deformation force for the support block 122, thereby facilitating the improvement of the buffering and pushing effects of the guide member body 10 on the front longitudinal beam 30.

[0042] Specifically, the mounting portion 11 includes a first mounting block 111, and the fixing portion 12 is fixedly connected to the first mounting block 111; a first screw hole 1111 is provided on the first mounting block 111. During specific implementation, the first mounting block 111 cooperates with the first screw hole 1111 through a screw 50 to achieve a firm connection between the guide member body 10 and the anti-collision beam 20.

[0043] Specifically, the mounting portion 11 includes a second mounting block 112 and a limiting block 113, and the limiting block 113 is fixedly connected to a side of the first mounting block 111 away from the fixing portion 12; the second mounting block 112 is arranged parallel to the first mounting block 111 and is fixedly connected to the limiting block 113, and the first mounting block 111, the second mounting block 112, and the limiting block 113 enclose a slot 114. During specific implementation, the slot 114 is aligned with the beam wall of the anti-collision beam 20 so that the second mounting block 112 is inserted into the anti-collision beam 20, and at the same time, the first mounting block 111 abuts against the outer side wall of the anti-collision beam 20. The mounting portion 11 realizes the connection between the guide member body 10 and the anti-collision beam 20 through a double connection method of plugging and screwing, greatly improving the mounting stability of the guide member body 10, avoiding the separation of the guide member body 10 from the anti-collision beam 20 during vehicle driving or collision, and thus ensuring the effectiveness and reliability of the vehicle body collision offset response mechanism.

[0044] Specifically, a second screw hole 1121 is provided on the second mounting block 112 corresponding to the first screw hole 1111. The setting of the second screw hole 1121 enables the screw 50 to pass through and be screwed to the first screw hole 1111, the anti-collision beam 20, and the second screw hole 1121 in sequence, so that the first mounting block 111 and the second mounting block 112 respectively form a double locking structure with the anti-collision beam 20 from the inner and outer sides of the beam wall of the anti-collision beam 20, enhancing the connection strength between the guide member body 10 and the anti-collision beam 20, improving the stability and reliability of the anti-collision structure, reducing the risk of the guide member body 10 separating from the anti-collision beam 20, and maintaining the close connection between the guide member body 10 and the anti-collision beam 20.

[0045] Specifically, the second mounting block 112 is provided with a partition groove 1122 along the length direction of the mounting portion 11. The arrangement of the partition groove 1122 allows for a deformation space between the second mounting blocks 112, facilitating the insertion of the second mounting blocks 112 into the anti-collision beam 20 and reducing the installation difficulty of the guide member body 10. Moreover, a horizontal reinforcing support plate is usually provided in the middle of the anti-collision beam 20. The partition groove 1122 is arranged along the extension direction of the anti-collision beam 20 to adapt to the structure of the anti-collision beam 20, facilitating the second mounting block 112 to avoid the reinforcing support plate and insert into the anti-collision beam 20.

[0046] Specifically, the ends of the first mounting block 111 and the second mounting block 112 close to the slot 114 are both provided with guide surfaces 115. The two ends on the side of the second mounting block 112 away from the first mounting block 111 are also both provided with guide surfaces 115. The guide surfaces 115 are inclined, which is beneficial for guiding the first mounting block 111 and the second mounting block 112 to move along the beam wall of the anti-collision beam 20, facilitating the smooth insertion of the guide member body 10 into the anti-collision beam 20. At the same time, it is convenient to remove the second mounting block 112 from the anti-collision beam 20 to achieve the convenient disassembly of the guide member body 10.

[0047] Specifically, the second mounting block 112 and / or the first mounting block 111 is provided with a second weight-reducing hole 1123. The second weight-reducing hole 1123 effectively reduces the overall weight of the guide member body 10 and provides an elastic deformation force for the mounting portion 11, thereby facilitating the improvement of the disassembly and assembly efficiency of the mounting portion 11.

[0048] Embodiment 2

[0049] See Figures 1-4 As shown, this embodiment discloses an anti-collision structure. Specifically, it includes the guide member with the function of fixing the wire harness in Embodiment 1; the mounting portion 11 is connected to the anti-collision beam 20.

[0050] The anti-collision structure of this embodiment realizes the fixation of the wire harness 40 and the collision offset of the vehicle through the guide member body 10, making the layout of the anti-collision structure simple and the structure concise, effectively reducing the production cost of the vehicle, facilitating the improvement of the economic benefits of the vehicle, and at the same time providing a strong guarantee for the safety of the vehicle and passengers.

[0051] The anti-collision beam 20 is provided with a third screw hole 21. During specific implementation, the screw 50 can pass through and be screwed into the first screw hole 1111, the third screw hole 21, and the second screw hole 1121 in sequence, so that the first mounting block 111 and the second mounting block 112 are respectively screwed to the anti-collision beam 20 from the inner and outer sides of the beam wall of the anti-collision beam 20, improving the installation stability of the guide member body 10.

[0052] The anti-collision structure further includes a front longitudinal beam 30, and the front longitudinal beam 30 is fixedly connected to the anti-collision beam 20; the fixing part 12 is arranged between the anti-collision beam 20 and the front longitudinal beam 30. The guiding member body 10 is used to provide a thrust force for the front longitudinal beam 30, so that when one end of the anti-collision beam 20 approaches the front longitudinal beam 30, the front longitudinal beam 30 is offset by the acting force of the guiding member body 10, greatly reducing the collision time between the front longitudinal beam 30 and the anti-collision beam 20, and reducing the damage to the vehicle and the passengers during the vehicle collision; the guiding member body 10 is also used to fix the front cabin wiring harness, providing a strong guarantee for the stable connection between the front cabin wiring harness and the front bumper wiring harness.

[0053] This embodiment provides a guiding member and an anti-collision structure with a function of fixing a wiring harness. By arranging a fixing part on the guiding member body, a connection structure is provided for fixing the wiring harness, improving the utilization rate of the guiding member. It can not only realize the collision offset of the vehicle, but also realize the fixing of the wiring harness, making the guiding member highly integrated in function. There is no need to set an additional fixing structure to fix the wiring harness, saving production costs and simplifying the layout of the anti-collision structure, which is beneficial to the installation and maintenance of the vehicle; the arrangement of the fixing part enables the wiring harness to move along with the guiding member, avoiding the anti-collision beam from crushing or the collision object from piercing the wiring harness, greatly reducing the risk of vehicle failure and improving the reliability and safety of the vehicle.
