[0031] See also Figure 1As shown, an embodiment of the first aspect of the present invention provides a wire harness fixing assembly, the wire harness fixing assembly 1 is used to fix the high-voltage wire harness 2 between the power battery (not shown) of the car and the voltage converter 4 of the car, and includes a clamp 11 and a bracket 12, wherein the clamp 11 is used for the high-voltage wire harness 2 to pass through, and the bracket 12 is used to limit the swing amplitude of the high-voltage wire harness 2. Preferably, the clamp 11 and the bracket 12 are detachably connected to facilitate the replacement and maintenance of the high-voltage wire harness 2. It should be noted that the high-voltage wire harness 2 mentioned here refers to a wire harness with an operating voltage generally above 400V or a wire diameter greater than 10mm. 2 The power battery refers to the battery that provides power for the car; the voltage converter 4 is an important device for converting electric energy in the car. It can convert the high-voltage direct current output by the power battery into low-voltage direct current to meet the power supply needs of various low-voltage electrical equipment on the car.

[0032] like Figure 2 、 Figure 3 As shown, in this embodiment, the clamp 11 includes a base 111 and a pressure plate 112, wherein the pressure plate 112 is clamped to the base 111. Specifically, one end of the pressure plate 112 is hinged to the base 111, and the other end is clamped to the base 111. It should be noted that in order to facilitate the insertion of the high-voltage wire harness 2, a through harness hole 113 is formed between the base 111 and the pressure plate 112, and the inner diameter of the harness hole 113 is greater than or equal to the outer diameter of the high-voltage wire harness 2. In this way, when the high-voltage wire harness 2 needs to be fixed, the base 111 is first placed on the outer surface of the high-voltage wire harness 2, and then the pressure plate 112 is pressed to clamp the pressure plate 112 to the base 111. At this time, the outer surface of the high-voltage wire harness 2 is in contact with the inner wall of the harness hole 113, thus achieving a fixed connection of the clamp 11 to the high-voltage wire harness 2.

[0033] In order to make the clamp 11 and the bracket 12 detachably connected, in this embodiment, a hook-shaped clamping portion 114 is formed on one side of the clamping base 112, and the bracket 12 is provided with a clamping slot 128 adapted to the clamping portion 114. In this way, when the clamping base 112 is clamped into the clamping slot 128 through its clamping portion 114, the connection between the clamping base 112 and the bracket 12 can be achieved; when the high-voltage wire harness 2 needs to be replaced, the maintenance personnel can use auxiliary tools to disengage the clamping portion 114 from the clamping slot 128, and the high-voltage wire harness 2 can be quickly removed, which is beneficial to reducing the labor intensity of the maintenance personnel. In some embodiments, the detachable connection between the clamp 11 and the bracket 12 can also be implemented by a threaded connection. Specifically, corresponding threaded holes can be opened on the clamping base 112 of the clamp 11 and the bracket 12, and then the fastening screws can be installed in the threaded holes, which can also meet the detachable connection between the clamp 11 and the bracket 12.

[0034] In this embodiment, the bracket 12 is connected between the voltage converter 4 and the base 112. Specifically, the bracket 12 includes a main body 121, a first connecting portion 122, and a second connecting portion 123. The main body 121 is plate-shaped. The first connecting portion 122 extends upward from one side of the main body 121 and defines a connecting hole 127 for securely connecting to the voltage converter 4. The second connecting portion 123 is disposed opposite the first connecting portion 122 relative to the main body 121 and defines a slot 128 for securely engaging with the base 112. Thus, when a fastener (such as a fastening screw) is installed in the connecting hole 127 and a corresponding mounting hole on the voltage converter 4, the bracket 12 is securely connected to the voltage converter 4. It should be noted that to ensure that the bracket 12 can provide optimal support for the high-voltage wiring harness 2, the bending trend of the second connecting portion 123 of the bracket 12 is preferably aligned with the wiring direction of the high-voltage wiring harness 2, thereby preventing the high-voltage wiring harness 2 from cutting due to stress concentration.

[0035] Furthermore, to adapt to the wiring path of the high-voltage wiring harness 2, in this embodiment, the bracket 12 also includes a transition portion 124. The transition portion 124 is plate-shaped and located between the main body 121 and the second connecting portion 123. It is connected to or integrally formed with the main body 121 and the second connecting portion 123. Preferably, the angles between the transition portion 124 and the main body 121 and the second connecting portion 123 are all obtuse.

[0036] In this embodiment, to improve the structural strength of the bracket 12, a reinforcing rib 125 is formed at the intersection between the transition portion 124 and the second connecting portion 123. The reinforcing rib 125 is in the shape of a bump, extending outward from the intersection between the transition portion 124 and the second connecting portion 123, and connecting to the outer surface of the transition portion 124 and the outer surface of the second connecting portion 123.

[0037] Furthermore, the bracket 12 further includes a bent portion 126, which is formed at an edge of the bracket 12. Specifically, the bent portion 126 refers to a flange formed at two opposite edge positions on the bracket 12. Preferably, the bent portion 126 is bent along a direction away from the high-voltage wire harness 2 to avoid damage to the outer surface of the high-voltage wire harness 2.

[0038] In some embodiments, to address the issue of increased wear of the high-voltage wiring harness 2 due to factors such as road conditions, powertrain vibration, and vehicle body vibration, the wiring harness securing assembly 1 further includes an anti-slip bushing (not shown). The anti-slip bushing is mounted within the clamp 11 and is insulated from the high-voltage wiring harness 2. Preferably, the anti-slip bushing is made of a soft, insulating material to reduce or even isolate vibration loads transmitted to the high-voltage wiring harness 2.

[0039] An embodiment of the second aspect of the present utility model provides a power system, including a power battery, a voltage converter 4, a high-voltage wire harness 2, and a wire harness fixing assembly 1 as described in the above embodiment, wherein the high-voltage wire harness 2 is connected between the power battery and the voltage converter 4, the bracket 12 of the wire harness fixing assembly 1 is fixedly connected to the voltage converter 4, and is fixedly connected to the high-voltage wire harness 2 through the clamp 11 of the wire harness fixing assembly 1, so that the above-mentioned power system can continuously output stable power during use.

[0040] An embodiment of the third aspect of the present invention provides an automobile, comprising the power system as described in the above embodiment, so that the driving safety index of the above automobile is higher.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] The present invention adds a wire harness fixing assembly 1 to the high-voltage wire harness 2 between the power battery and the voltage converter 4 of the automobile, which not only improves the stability of the high-voltage wire harness 2, but also helps to avoid the risk of wire cutting caused by factors such as road conditions, jitter of the power system and vibration of the vehicle body, thereby meeting the requirements for safe use of the automobile.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
