Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage line installation equipment for new energy vehicles, and in particular to a high-voltage line bracket. Background Art

[0002] Automotive wiring harnesses can be generally divided into two types: high-voltage and low-voltage. Traditional fuel vehicles primarily use low-voltage harnesses, while new energy vehicles primarily use high-voltage harnesses. High-voltage harnesses can be configured for internal and external wiring harness connections in electric vehicles according to different voltage levels. Their primary function is to efficiently and effectively transmit electrical energy and shield against external signal interference. The high-voltage harness is the neural network of the high-voltage system in new energy vehicles and is extremely important, especially since the drive motor has high requirements for securing the high-voltage harness. The high-voltage wires supplying the drive motor will vibrate along with the drive motor. Currently, the market often encounters problems such as excessive vibration, dynamic interference between the high-voltage harness and other components, and loose high-voltage connectors, resulting in the loss of high voltage during driving, causing installation and throwing failures.

[0003] For example, publication number CN209748102U, published on December 6, 2019, disclosed a new energy motor harness bracket, comprising a first bracket portion, which is a long strip-shaped cover plate. The top of the first bracket portion is connected to a second bracket portion, which is a rectangular box with a hollow interior and open ends. The second bracket portion is perpendicular to the first bracket portion, and one opening of the second bracket portion is connected to one side of the first bracket portion. When the bracket disclosed above is used to secure high-voltage wires, motor vibration can easily cause the high-voltage wire connector to fall off, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this utility model is to provide a high-voltage wire bracket that prevents the high-voltage wire connector from falling off and has higher practicality. The utility model stably connects the high-voltage wire to the mounting bracket through a cable tie, thereby effectively fixing the high-voltage wire to the drive motor housing and preventing the high-voltage wire connector from loosening.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve its technical problems is: a high-voltage wire bracket, including a mounting bracket clamped with the high-voltage wire, the mounting bracket is connected to the motor housing, and the mounting bracket is provided with a mounting hole, and the mounting hole on the mounting bracket is connected to the high-voltage wire through a cable tie.

[0006] The mounting frame includes two arc-shaped plates clamped with the high-voltage wire, the two arc-shaped plates are provided with support plates fitted with the motor housing, the support plates are provided with mounting plates, and the mounting plates are connected to the motor housing through bolts.

[0007] A first transition plate is provided between the two arc-shaped plates, and the arc-shaped plates are connected to the support plate through a second transition plate.

[0008] The mounting hole includes a first notch and a second notch, the first notch is provided on the first transition plate, and the second notch is provided on the second transition plate.

[0009] The first notch and the second notch both extend to the arc-shaped plate.

[0010] The arc plate, the first transition plate and the second transition plate are M-shaped, one end of the support plate is connected to the second transition plate, and the other end of the support plate is connected to the mounting plate.

[0011] The support plate is provided with convex ribs.

[0012] The support plate is provided with a flange.

[0013] The two mounting plates are respectively provided with positioning through holes and connecting through holes.

[0014] The cross section of the positioning through hole is circular, and the cross section of the connecting through hole is strip-shaped.

[0015] The beneficial effects of the utility model are:

[0016] The mounting bracket is clamped to the high-voltage wire. After clamping, the cable tie is passed through the mounting hole on the mounting bracket to connect the high-voltage wire to the mounting bracket. The mounting bracket is then installed on the motor housing to achieve stable installation of the high-voltage wire and prevent the connector of the high-voltage wire from loosening on the motor housing, which is more practical.

[0017] The mounting frame uses a combination of curved plates and cable ties to fix the high-voltage wires, which is firm and reliable. When the motor jumps up and down, the high-voltage wires and the curved plates are in surface contact, which can effectively resist longitudinal jumps. The support plate is provided with flanges and rib structures, which have high rigidity. When receiving impact loads, the deformation is small, the displacement of the high-voltage wire is small, and the dynamic interference between the high-voltage wires and surrounding parts is prevented.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] like Figure 1-2 As shown, the high-voltage wire bracket includes a mounting frame 1 that is clamped with the high-voltage wire 13. The mounting frame 1 is connected to the motor housing. A mounting hole 2 is provided on the mounting frame 1. The mounting hole 2 on the mounting frame 1 is connected to the high-voltage wire through a cable tie 12. In this embodiment, two high-voltage wires 13 are provided.

[0024] When in use, the mounting bracket 1 is clamped with the high-voltage wire 13, and after clamping, the cable tie 12 is passed through the mounting hole 2 on the mounting bracket 1 to connect the high-voltage wire 13 to the mounting bracket 1, and then the mounting bracket 1 is installed on the motor housing, thereby achieving stable installation of the high-voltage wire 13 and preventing the connector of the high-voltage wire 13 from loosening on the motor housing, which is more practical.

[0025] The mounting frame 1 includes two arc-shaped plates 3 that are clamped with the high-voltage wire 13. The two arc-shaped plates 3 are provided with support plates 6 that fit with the motor housing. The support plates 6 are provided with mounting plates 7. The mounting plates 7 are connected to the motor housing by bolts. The arc-shaped plates 3 are used to achieve a stable connection between the mounting frame 1 and the high-voltage wire 13, and the two support plates 6 are stably fitted with the surface of the motor housing to achieve a stable connection between the mounting frame 1 and the motor housing. The mounting plates 7 are connected to the motor housing by bolts, thereby achieving convenient disassembly and assembly of the mounting frame 1. In this embodiment, two support plates 6 are provided.

[0026] A first transition plate 4 is provided between the two arc-shaped plates 3, and a stable connection between the two arc-shaped plates 3 is achieved through the first transition plate 4. The arc-shaped plates 3 are connected to the support plate 6 through the second transition plate 5, so that the second transition plate 5 facilitates the stable connection between the arc-shaped plates 3 and the support plate 6, and facilitates the support plate 6 to fit with the surface of the motor housing, thereby achieving stable connection of the mounting frame 1.

[0027] The mounting hole 2 includes a first slot 201 and a second slot 202. The first slot 201 is arranged on the first transition plate 4, and the second slot 202 is arranged on the second transition plate 5. The two cable ties 12 pass through the first slot 201 and the second slot 202 respectively, thereby stably tying the high-voltage line 13 to the curved plate 3, thereby achieving stable installation of the high-voltage line 12.

[0028] The first notch 201 and the second notch 202 both extend onto the curved plate 3 , thereby ensuring that the cable tie 12 passing through the first notch 201 and the second notch 202 can stably fix the high-voltage wire 13 on the curved plate 3 .

[0029] Specifically, the arc plate 3, the first transition plate 4 and the second transition plate 5 are M-shaped, thereby realizing a stable connection between the two arc plates 3 and the two high-voltage wires 13. One end of the support plate 6 is connected to the second transition plate 5, and the other end of the support plate 6 is connected to the mounting plate 7, thereby ensuring that the mounting plate 7 is stably fitted with the surface of the motor housing during installation. Specifically, the support plate 6 is arranged at the bottom end of the second transition plate 5, and the support plate 6, the second transition plate 5 and the mounting plate 7 are perpendicular to each other.

[0030] The support plate 6 is provided with ribs 10 , thereby increasing the structural rigidity of the support plate 6 .

[0031] The support plate 6 is provided with a flange 11 , which increases the structural rigidity of the support plate 6 and prevents the high-voltage wire 13 from pulling the mounting frame 1 and causing deformation when the drive motor jumps up and down.

[0032] The two mounting plates 7 are respectively provided with positioning holes 8 and connecting holes 9. The positioning holes 8 are used to connect with the positioning columns on the motor housing to achieve positioning work during installation of the mounting frame 1, and the connecting holes 9 are used for connecting work by allowing bolts to pass through.

[0033] Specifically, the cross section of the positioning through hole 8 is circular, and the cross section of the connecting through hole 9 is strip-shaped, thereby ensuring that the bolt passes through the connecting through hole 9 and is stably connected to the motor housing.

[0034] In summary: the mounting frame 1 uses a combination of an arc-shaped plate 3 and a cable tie 12 to fix the high-voltage wire 13, which is firmly and reliably fixed. When the motor jumps up and down, the high-voltage wire 13 is in surface contact with the arc-shaped plate 3, which can effectively resist longitudinal jumping. The support plate is provided with a flange 11 and a convex rib 10 structure, which has high rigidity. When receiving an impact load, the deformation is small, and the displacement of the high-voltage wire 13 is small, which prevents the high-voltage wire 13 from dynamically interfering with surrounding parts.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
