Technical Field
[0001] The utility model relates to the technical field of wire harness fixing devices, in particular to a fixing bracket for a multi-directional bending wire harness of an automobile engine. Background Art
[0002] The engine is an important component in the car. In the car engine, there are many wire harnesses connected to other components. In order to prevent the heat from the engine block from being transferred to the wire harness, causing the wire harness to overheat and cause a safety accident, it is necessary to install a fixed bracket to avoid direct contact between the new book and the engine block. Since the installation station space around the engine block is limited, it is necessary to improve the space utilization as much as possible. Therefore, the wire harness inevitably needs to be bent to meet the space requirements, and some wire harnesses need to be bent not only once, but may need to be bent multiple times. The wire harness itself has a certain flexibility. After multiple bends, the wire harness has a large rebound force on the fixed bracket, which makes it difficult to fix the wire harness. The existing fixed bracket has the following problems : First, the existing fixing bracket is usually combined with multiple fixing brackets to fix the multi-directional bent wire harness, but this will result in the need to set up multiple installation stations on the engine cylinder block for installing the fixing bracket, which will reduce the space utilization rate; second, the fixing bracket is usually connected by fixing bolts during the installation process, but since the wire harness has a large rebound force on the fixing bracket, it is difficult for the staff to align the mounting holes on the fixing bracket with the mounting holes on the engine with both hands at the same time; third, in the prior art, in order to ensure that the wire harness is fixed on the fixing bracket, the wire harness and the fixing bracket are usually tied together by a cable tie, but the gap between the existing fixing bracket and the wire harness is large, so the cable tie has a poor fixing effect on the wire harness. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a fixing bracket for a multi-directional bending wire harness of an automobile engine, which can ensure the stability of the wire harness position, improve space utilization, and facilitate installation by workers.

[0005] By adopting the above technical scheme, when assembling the fixed bracket, first, the wire harness is installed on the bracket body, and then the block assembly is quickly installed on the cylinder block of the engine, so that the staff can free up their hands to align the mounting hole on the second mounting block on the bracket body with the position of another mounting station on the engine cylinder block, which can greatly improve the installation efficiency of the staff. In addition, since the central axis of the front part of the bracket and the central axis of the middle part of the bracket are in the same plane and at a certain angle, and the central axis of the middle part of the bracket is perpendicular to the central axis of the rear part of the bracket, when the wire harness is placed on the bracket body, the wire harness can be bent in multiple directions. The position of the wire harness is limited by the bracket body to ensure the position stability of the wire harness. In addition, when the position of the wire harness is fixed, the wire harness is connected to the bracket body by a cable tie, thereby further improving the position stability of the wire harness and improving the space utilization of the fixed bracket. The utility model is further configured as follows: a plurality of cable tie grooves are provided on the bracket body, and every two cable tie grooves form a cable tie groove group, and the positions of the cable tie grooves on the same cable tie groove group are axially symmetrically arranged with the central axis of the bracket body as the central axis.
[0006] With the above technical solution, since a plurality of tie grooves are provided on the bracket body, when the tie is tied on the tie groove, the gap between the tie and the bracket body can be reduced, thereby improving the position stability of the wire harness.
[0007] The utility model is further configured as follows: the number of the tie slot groups is four, and the positions of the tie slot groups are respectively located at the end of the front part of the bracket, the connection between the front part of the bracket and the middle part of the bracket, the connection between the middle part of the bracket and the rear part of the bracket, and the end of the rear part of the bracket.
[0008] By adopting the above technical solution, since there are four cable tie groove groups, and the positions of the cable tie groove groups are respectively located at the end of the front part of the bracket, the connection between the front part of the bracket and the middle part of the bracket, the connection between the middle part of the bracket and the rear part of the bracket, and the end of the rear part of the bracket, the position stability of the wiring harness can be further improved.
[0009] Further configuration of the utility model: the block assembly includes a protrusion fixedly connected to the first mounting block and two elastic support plates connected to the protrusion, the two elastic support plates are symmetrically arranged with the central axis of the protrusion as the axis center, and two limiting grooves are provided on the protrusion, the two limiting grooves correspond to the positions of the two elastic support plates respectively, and the limiting grooves are adapted to the shape and size of the elastic support plates.
[0010] By adopting the above technical solution, since the block assembly includes a protrusion fixedly connected to the first mounting block and two elastic support sheets connected to the protrusion, when the block assembly is inserted into the mounting position on the engine cylinder block, the two elastic support sheets are squeezed and move toward the position of the limiting groove, so that the block assembly can be smoothly inserted into the mounting position on the engine cylinder block. After the block assembly is inserted, the elastic support sheets will automatically reset due to the elastic action, so that the position of the block assembly is stuck. In this way, the block assembly can be stably fixed on the engine cylinder block under the premise that the size of the block assembly is small. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, since the central axis of the front part 4 of the bracket and the central axis of the middle part 5 of the bracket are in the same plane and at a certain angle, and the central axis of the middle part 5 of the bracket is perpendicular to the central axis of the rear part 6 of the bracket, when the wire harness is placed on the bracket body 1, the wire harness can be bent in multiple directions.
