Technical Field
[0001] The utility model belongs to the technical field of wire harness fixing, and specifically relates to a three-phase wire fixing device for a new energy vehicle motor. Background Art
[0002] In recent years, the Chinese government has given strong support to the new energy vehicle industry, and has promoted the rapid development of the new energy vehicle industry through policy guidance, scientific and technological innovation, and infrastructure construction. At present, China has become the world's largest producer and seller of new energy vehicles. The three-phase wire of the motor is the core high-voltage wire harness in new energy vehicles and will move with the movement of the drive motor. Therefore, the fixing method of the three-phase wire is particularly important. It is necessary to ensure its flexible connection to avoid the wire harness being broken due to bending stress and to limit its range of movement to avoid the wire harness being worn by surrounding components.
[0003] However, in the prior art, car companies prefer to use a structure composed of two high-voltage wire harness fixing support blocks with the same structure as described in the patent application number 202121042979.0, but it can only ensure the flexible connection of the three-phase line but cannot limit the range of movement of the three-phase line. Utility Model Content
[0004] The purpose of the utility model is to solve the problem in the background technology that the flexible connection of the three-phase line of the motor can only be guaranteed but the activity range of the three-phase line cannot be limited, and a three-phase line fixing device for the motor of a new energy vehicle is proposed.
[0005] In order to achieve the above purpose, the specific scheme of the utility model is:
[0006] A three-phase line fixing device for a new energy vehicle motor comprises a three-phase line rubber block unhooking bracket (1), a three-phase line rubber block unhooking bracket (2), and a three-phase line rubber block (3). The three-phase line rubber block unhooking bracket (1) has an arched structure in the middle that is adapted to the head of the three-phase line rubber block unhooking bracket (2) and is fixed by welding through a welding point 1 (13). A fixed limiting hole (31) is provided at the top of the three-phase line rubber block (3). The fixed limiting hole (31) is connected to the tail of the three-phase line rubber block unhooking bracket (2) in a clamping manner.
[0007] Preferably, the three-phase line rubber block unhooking bracket (1) has a fixed bracket 1 (11) and a fixed bracket 2 (12) on the left and right sides, which are respectively fixed to the vehicle body by welding at welding points 2 (14) and welding points 3 (15).
[0008] Preferably, the tail of the three-phase line rubber block decoupling (2) is in a conical frustum structure.
[0009] Preferably, the bottom end of the three-phase wire rubber block (3) is provided with three wire harness through holes (32, 33, 34) adapted to the three-phase wires of the motor, and all are chamfered.
[0010] The beneficial effects of the utility model are:
[0011] The utility model ensures the flexible connection of the three-phase wire of the motor through the clamping relationship between the three-phase wire rubber block and the three-phase wire rubber block towing hook, avoiding the risk of the three-phase wire breaking due to stress concentration; and the three-phase wire rubber block towing hook bracket is fixed to the vehicle body by welding to limit the range of movement of the three-phase wire of the motor, avoiding interference and wear between the three-phase wire and surrounding components.

DETAILED DESCRIPTION
[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0020] In the description of the present invention, it should be understood that the terms "left", "right", "top", "bottom", "head", "tail", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0021] like Figure 1-3As shown, the utility model provides a three-phase line fixing device for a new energy vehicle motor, comprising a three-phase line rubber block unhooking bracket (1), a three-phase line rubber block unhooking (2), and a three-phase line rubber block (3). The three-phase line rubber block unhooking bracket (1) has an arched structure in the middle that is adapted to the head of the three-phase line rubber block unhooking (2) and is fixed by welding through a welding point 1 (13). The top of the three-phase line rubber block (3) is provided with a fixed limiting hole (31), and the fixed limiting hole (31) is connected to the tail of the three-phase line rubber block unhooking (2) in a clamping form.
[0022] like Figure 1-4 As shown, the three-phase line rubber block unhooking bracket (1) has a fixing bracket 1 (11) and a fixing bracket 2 (12) on the left and right sides, which are respectively fixed to the vehicle body by welding points 2 (14) and 3 (15). The three-phase line rubber block towing hook bracket is fixed to the vehicle body by welding, which not only ensures the fixing reliability but also limits the range of movement of the motor three-phase line, thereby avoiding interference and wear between the three-phase line and surrounding components.
[0023] like Figure 1-5 As shown, the tail of the three-phase line rubber block unhooking (2) is a conical truncated cone structure, and the conical structure is easier to pass through the fixed limiting hole (31) on the three-phase line rubber block (3). The truncated cone structure plays a limiting role after being matched, effectively preventing the three-phase line rubber block (3) from falling off. The clamping connection method of the three-phase line rubber block and the three-phase line rubber block towing hook can ensure the flexible connection of the motor three-phase line, avoiding the risk of three-phase line breaking due to stress concentration.
[0024] like Figure 1-6 As shown, the bottom end of the three-phase wire rubber block (3) is provided with three wire harness through holes (32, 33, 34) adapted to the three-phase wire of the motor, and all are chamfered to ensure the convenience of assembling the three-phase wire of the motor.
[0025] The utility model discloses a three-phase wire fixing device for a new energy vehicle motor, which is easy to assemble as a whole and only requires the three-phase wire rubber block to be unhooked (2) and the three-phase wires of the motor to be respectively connected and punched with the three-phase wire rubber block (3).
