Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a high-voltage wiring harness fixing bracket for automobiles. Background Technology

[0002] Wiring harnesses consist of insulating sheaths, terminals, and wires. They are widely used in the automotive industry, serving as wiring components to connect various electrical devices in the automotive circuit and enable them to function. The rational arrangement of wiring harnesses can not only reduce the overall size of the engine and optimize specialized components, but also reduce wiring harness-related costs and improve wiring harness safety.

[0003] With the continuous improvement of the configuration and driving range of electric and hybrid vehicles, the number of in-vehicle electronic control components has surged, and the current in the wiring harness is getting larger and larger. Therefore, the wiring harness is often replaced with a large-cross-section high-voltage wiring harness. In order to avoid the wiring harness from getting tangled and affecting surrounding components, it is usually necessary to use cable ties, wiring harness connectors or wiring harness brackets to fix the high-voltage wiring harness to the sheet metal of the vehicle body structure, so as to control the wiring harness routing.

[0004] However, cable ties have low strength, making it easy for wire harnesses to come loose, and it is very difficult to find the problematic wire harness in a large bundle later. Although wire harness connectors can provide good fixation, they are prone to making abnormal noises, and in severe cases, they can even cause the wire harness surface to break. The invention application with publication number CN120171440A discloses "a wire harness fixing bracket". This bracket can effectively reduce the temperature of the wire harness through the design of heat dissipation components, but when a problem occurs in a wire harness, the entire pressure plate or partition needs to be disassembled, which will cause multiple wire harnesses in the single wire harness channel to lose fixation at the same time, and there is also the problem of the wire harness slipping out of the stabilizing groove. Utility Model Content

The movable limiting component rotates relative to the support, causing the corresponding wire harness channel to switch between an open state and a closed state.

[0007] Furthermore, the active limiting component includes: The limiting body is cylindrical, with its axis perpendicular to the surface of the support seat, and is located on one side of the arc-shaped groove; a first guide groove is provided inside the limiting body, and the first guide groove penetrates the limiting body; A pressure plate is fixed to the limiting body on the side near the arc-shaped groove and is located directly above the arc-shaped groove; A guide post is inserted into the first guide groove and its position relative to the support is fixed; the limiting body slides along the direction of the guide post and rotates relative to the support about the guide post as a pivot.

[0008] Furthermore, the end of the guide post is provided with a rectangular limiting block; the end of the first guide groove away from the support is provided with a limiting groove, the shape and size of which are adapted to the limiting block; a cylindrical groove is also provided inside the limiting body, the cylindrical groove is located directly below the limiting groove and is connected to the limiting groove; the diameter of the cylindrical groove is greater than the diagonal length of the limiting block.

[0009] Furthermore, the surface of the limiting body is provided with a first annular groove around the first guide groove, and the surface of the support seat is provided with a plurality of second annular grooves, the plurality of second annular grooves being respectively positioned corresponding to the first annular groove.

[0020] Please see Figures 1 to 4 The illustrated embodiment of this application provides a high-voltage wiring harness mounting bracket for automobiles. In practical applications, the high-voltage wiring harness mounting bracket can be installed and fixed to the vehicle body structure in the engine compartment or passenger compartment. During installation, the high-voltage wiring harness is first classified using wiring harness corrugated tubing, and then the wiring harness corrugated tubing is connected to the high-voltage wiring harness mounting bracket. This effectively solves the problem of damage caused by direct contact and collision between the high-voltage wiring harness and the vehicle body structure due to vehicle vibration. Please refer to [link to relevant documentation]. Figure 1 The automotive high-voltage wiring harness fixing bracket includes: a support arm 1, a support seat 2, and a movable limiting component 3.

[0021] As one embodiment of this application, the support arm 1 is generally strip-shaped with a Z-shaped longitudinal section. One end of the support arm 1 can be detachably connected to the car frame by bolts or fixed to the car frame by welding. The other end of the support arm 1 is set as a free end, and the support seat 2 uses the free end of the support arm 1 as the mounting plane.

[0022] To adapt to the complex installation environment inside the engine compartment, as another embodiment of this application, a support arm 1 with a U-shaped longitudinal section can also be adopted. In this embodiment, both ends of the support arm 1 are connected to the vehicle frame, and the support seat 2 uses the flat area in the middle of the support arm 1 as the installation plane.

[0023] In the above technical solution, the support arm 1 is made of aluminum alloy or carbon steel, so that the fixed bracket has a lighter weight while meeting the connection strength requirements.

[0024] Please see Figure 2 The support seat 2 is generally in the form of a strip block structure. The support seat 2 is connected to the free end of the support arm 1. Several arc-shaped grooves 21 are arranged on the side of the support seat 2 away from the support arm 1. In this embodiment, the arc-shaped grooves 21 are semi-cylindrical. The axis of the arc-shaped grooves 21 is perpendicular to the length direction of the support seat 2. After a single wire harness corrugated tube is placed in the corresponding arc-shaped groove 21, it can fit against the surface of the arc-shaped groove 21, thereby preventing the wire harness corrugated tube from rolling and achieving the effect of initially limiting the wire harness corrugated tube.

[0025] To ensure the wire harness corrugated tube is securely locked in the arc-shaped groove 21, and also to allow for easy removal during wire harness fault detection, please refer to [link to relevant documentation]. Figure 2 and Figure 3 The support 2 is also connected to several movable limiting components 3. The movable limiting components 3 are located on the side of the support 2 away from the support arm 1. The number of movable limiting components 3 matches the number of arc-shaped grooves 21, and each movable limiting component 3 corresponds one-to-one with the position of an arc-shaped groove 21. The movable limiting components 3 and the corresponding arc-shaped grooves 21 cooperate to form a wire harness channel for accommodating the wire harness corrugated tube. In the above technical solution, the movable limiting components 3 can rotate relative to the support 2, allowing the corresponding wire harness channel to switch between an open state and a closed state. When the wire harness channel is in the open state, the wire harness corrugated tube is unlocked, making it easy for operators to handle and maintain. When the wire harness channel is in the closed state, the movable limiting components 3 press the wire harness corrugated tube tightly against the arc-shaped groove 21.

[0026] Specifically, the active limiting component 3 includes: a limiting body 31, a pressure plate 32, a guide post 33, and a reset component 34; wherein, the limiting body 31 has a cylindrical structure, and its axis is perpendicular to the surface of the support 2, and the limiting body 31 is located on one side of the arc groove 21; the pressure plate 32 is fixed on the limiting body 31 on the side near the arc groove 21, and is located directly above the arc groove 21, for cooperating with the arc groove 21 to press the wire harness corrugated tube.

[0027] It is understood that a first guide groove is provided inside the limiting body 31, and the first guide groove passes through the limiting body 31. A second guide groove is provided on the support 2 at a position corresponding to the first guide groove, and the second guide groove passes through the support 2. The guide post 33 passes through the first guide groove and the second guide groove, and its position relative to the support 2 is fixed, so that the limiting body 31 can slide along the direction of the guide post 33, and can also rotate relative to the support 2 with the guide post 33 as the pivot, thereby driving the pressure plate 32 to move closer to or away from the arc groove 21.

[0028] Furthermore, a rectangular limiting block 331 is provided at the end of the guide post 33, and a limiting groove 311 for accommodating the limiting block 331 is provided at the end of the first guide groove away from the support 2. The shape and size of the limiting groove 311 match the limiting block 331, so that when the limiting block 331 is located in the limiting groove 311, the limiting body 31 and the support 2 cannot rotate relative to each other, and can only move closer to or away from the support 2 along the direction of the guide post 33. A cylindrical groove 312 is also provided inside the limiting body 31. The cylindrical groove 312 is located directly below the limiting groove 311 and is connected to the limiting groove 311. The diameter of the cylindrical groove 312 is larger than the diagonal length of the limiting block 331, so that when the limiting block 331 is located in the cylindrical groove 312, the limiting body 31 and the support 2 can rotate relative to each other.

[0029] Using the above technical solution, when the wire harness channel is in the closed state, the limiting block 331 is located in the limiting groove 311. At this time, the pressure plate 32 presses the wire harness corrugated tube against the arc groove 21, and the limiting body 31 is locked and cannot be rotated. When it is necessary to open the wire harness channel to load or replace the wire harness corrugated tube, first move the limiting body 31 away from the support seat 2, so that the limiting block 331 enters the cylindrical groove 312 from the limiting groove 311 to unlock the limiting body 31. Then rotate the limiting body 31 so that the pressure plate 32 leaves the top of the arc groove 21, and the wire harness channel is in the open state, so that the wire harness corrugated tube in the corresponding wire harness channel can be taken out.

[0030] To prevent the limiting block 331 from moving into the cylindrical groove 312 and unlocking the limiting body 31 due to factors such as the downward installation angle of the fixed bracket or vehicle vibration, thus causing the wire harness corrugated tube to lose its fixation and slip, a reset component 34 is provided. (See also...) Figure 4 The reset component 34 includes: a reset spring 341 and a planar thrust bearing 342; the surface of the limiting body 31 is provided with a first annular groove around the first guide groove, and the surface of the support seat 2 is provided with a plurality of second annular grooves around the second guide groove, the plurality of second annular grooves corresponding to the positions of the first annular grooves; the planar thrust bearing 342 is located in the first annular groove, one side of its seat ring is fixedly connected to the limiting body 31, and the other side of its seat ring is close to the support seat 2; the reset spring 341 is located in the second annular groove, one end of its fixedly connected to the support seat 2, and the other end of its fixedly connected to the seat ring of the planar thrust bearing 342 corresponding to the first annular groove.

[0031] In the above technical solution, the reset spring 341 is a tension spring. With this design, when the limiting block 331 is located in the limiting groove 311, the reset spring 341 can pull the limiting body 31, so that the limiting body 31 remains close to the support seat 2, thereby preventing the limiting body 31 from moving without human intervention, causing the limiting block 331 to enter the cylindrical groove 312 and the limiting body 31 to unlock.

[0032] The automotive high-voltage wiring harness fixing bracket provided in this application uses a support base 2 to classify and fix different types of wiring harnesses in their corresponding wiring harness channels, facilitating the location of problematic wiring harnesses. By designing a movable limiting component 3 that cooperates with the support base 2, operators can open one or more corresponding wiring harness channels as needed, effectively avoiding interference with unrelated wiring harness corrugated pipes when loading or repairing target wiring harnesses. It has the advantages of high wiring harness constraint reliability and convenient operation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
