[0045] The embodiments of the present application provide a vehicle. It should be noted that the vehicle in this application can refer to a large automobile, a small car, a special-purpose vehicle, etc. For example, based on the vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle types. A vehicle generally has wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit power provided by the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0046] It should be noted that in the embodiments of the present application, the vehicle is an electric vehicle or a hybrid vehicle. For an electric vehicle, the power source may be an electric motor; for a hybrid vehicle, the power source may be an engine or an electric motor.

[0047] refer to Figure 1 、 Figure 2 and Figure 7 An embodiment of the present application provides a wire protection box for a power system of a vehicle, the power system including a drive assembly 500 , and the wire protection box including: a box body 100 , a connecting device 200 and a wiring harness fixing member 300 .

[0048] Among them, the box body 100 is provided with a wire harness fixing surface 121 and a fixing hole 130. The wire harness fixing surface 121 is suitable for fixing the power wire harness 400 of the drive assembly 500. The wire harness fixing surface 121 is an arc surface, which can improve the fit tightness between the power wire harness 400 and the wire harness fixing surface 121, thereby improving the installation stability of the power wire harness 400. The fixing hole 130 can be arranged adjacent to the wire harness fixing surface 121.

[0049] The connecting device 200 is provided on the box body 100 and is fixedly connected to the driving assembly 500 .

[0050] The harness fixing part 300 surrounds the power harness 400 and passes through the fixing hole 130 to fix the power harness 400 to the harness fixing surface 121. Since the fixing hole 130 is arranged adjacent to the harness fixing surface 121, it is beneficial to increase the binding force of the harness fixing part 300 on the power harness 400.

[0051] Exemplarily, the wire harness fixing surface 121 is an arc-shaped surface, the curvature of the arc-shaped surface is consistent with the curvature of the outer wall of the power wire harness 400, and the arc-shaped surface is arranged along the length direction of the power wire harness 400, so that the wire harness fixing surface 121 can better fit with the power wire harness 400, thereby ensuring the fixing effect between the wire harness fixing surface 121 and the power wire harness 400.

[0052] For example, the connecting device 200 may be a structure such as a bolt or a fixing pin, and the box body 100 is connected to the driving assembly 500 via the bolt.

[0053] Exemplarily, the harness fixing part 300 can be a binding wire, a cable tie, a strap, a rope, a metal ring or other components suitable for binding the power harness 400. The harness fixing part 300 is passed through the fixing hole 130 and wrapped around the power harness 400, thereby fixing the power harness 400 on the harness fixing surface 121.

[0054] By adopting the above technical solution, by setting the box body 100, the connecting device 200 and the harness fixing part 300, the box body 100 is provided with a harness fixing surface 121 and a fixing hole 130, the power harness 400 abuts against the harness fixing surface 121, the harness fixing part 300 passes through the fixing hole 130 and surrounds the power harness 400, fixing the power harness 400 on the harness fixing surface 121, and the box body 100 is fixed to the drive assembly 500 through the connecting device 200, thereby realizing the connection between the power harness 400 and the drive assembly 500, so that the vibration frequencies of the power harness 400 and the drive assembly 500 are relatively the same or close, thereby avoiding relative movement due to the large difference in vibration frequencies between the power harness 400 and the drive assembly 500, causing wear on the power harness 400, which is beneficial to improving the installation stability and service life of the power harness 400.

[0055] In some embodiments of the present application, the box body 100 may include a first side surface 110 along a first direction, and a second side surface 120 along a second direction. At least part of the structure of the second side surface 120 is formed as a wiring harness fixing surface 121. The wiring harness fixing surface 121 extends circumferentially along the power harness 400 of the drive assembly 500. The box body 100 is also provided with a fixing hole 130 passing through the second side surface 120 along the second direction. The fixing hole 130 is arranged adjacent to the wiring harness fixing surface 121.

[0056] For example, the first side surface 110 may be a flat surface or a curved surface, as long as the first side surface 110 is completely in contact with the driving assembly 500 .

[0057] refer to Figure 1 There are at least two fixing holes 130, for example, there may be two, three or more fixing holes, and at least two fixing holes 130 are respectively located on both sides of the harness fixing surface 121 along the third direction. The third direction, the second direction and the first direction are perpendicular to each other.

[0058] The first direction refers to Figure 1 The Y direction in the second direction refers to Figure 1 The X direction in the third direction is Figure 1 The Z direction in .

[0059] Exemplarily, there are two fixing holes 130 , and the two fixing holes 130 are connected, so that one end of the wire harness fixing piece 300 can pass through the two fixing holes 130 in sequence.

[0060] By adopting the above technical solution and providing at least two fixing holes 130 , it is convenient to fix the power harness 400 on the harness fixing surface 121 using the harness fixing member 300 , and the installation reliability of the power harness 400 can be enhanced.

[0061] Further, in some embodiments of the present application, reference is made to Figure 1 and Figure 2 The box body 100 may include a first box body portion 140 and a second box body portion 150. Specifically, the first box body portion 140 and the second box body portion 150 are arranged sequentially along the third direction. A portion of the second side surface 120 of at least one of the first box body portion 140 and the second box body portion 150 extends along the circumference of the power harness 400 to form a harness fixing surface 121.

[0062] Illustratively, the first box body 140 and the second box body 150 are integrally formed.

[0063] Illustratively, the second side surface 120 of the upper end portion of the first box body 140 extends along the circumference of the power harness 400 to form a harness fixing surface 121, and the connecting device 200 is arranged on the first side surface 110 of the second box body 150. After the box body 100 is fixed to the drive assembly 500 through the connecting device 200, the first box body 140 is located above the drive assembly 500 to provide installation space for the power harness 400.

[0064] By adopting the above technical solution, by setting the first box body 140 and the second box body 150, the box body 100 has a certain length along the third direction, providing installation space for the power harness 400, making it easier to install the power harness 400 on the drive assembly 500.

[0065] Further, in some embodiments of the present application, reference is made to Figure 1 and Figure 2 Part of the second side surface 120 of the first box body 140 extends along the circumference of the power harness 400 to form a harness fixing surface 121 .

[0066] One of the fixing holes 130 is formed in the first box body 140 and is located on the side of the wire harness fixing surface 121 away from the second box body 150 along the third direction. The other fixing hole 130 is formed in the second box body 150 and is located at one end of the second box body 150 close to the first box body 140.

[0067] For example, after the power harness 400 abuts against the harness fixing surface 121, the two fixing holes 130 are respectively located on both sides of the power harness 400 along the third direction. After the harness fixing member 300 passes through the two fixing holes 130, the two ends of the harness fixing member 300 are connected, thereby facilitating the use of the harness fixing member 300 to fix the power harness 400.

[0068] By adopting the above technical solution, the positions of the harness fixing surface 121 and the two fixing holes 130 are defined, which facilitates fixing the power harness 400 using the harness fixing member 300 .

[0069] Further, in some embodiments of the present application, reference is made to Figure 1 and Figure 2 , both ends of the second box body 150 along the second direction are open.

[0070] A plurality of reinforcing ribs 151 are provided on the inner side of the second box body 150 . The plurality of reinforcing ribs 151 divide the inner cavity of the second box body 150 into a plurality of mutually isolated sub-chambers.

[0071] Exemplarily, both ends of the second box body 150 along the second direction are open, so that the second box body 150 is in communication with the outside, thereby preventing water from accumulating in the second box body 150 .

[0072] Illustratively, the reinforcing ribs 151 are arranged in a plate shape, and a plurality of reinforcing ribs 151 are arranged vertically in sequence in the inner cavity of the second box body 150 , thereby strengthening the structural strength of the second box body 150 .

[0073] By adopting the above technical solution, not only is water accumulation in the second box body 150 avoided, but the structural strength of the second box body 150 is also ensured.

[0074] Further, in some embodiments of the present application, reference is made to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The connecting device 200 includes a connecting head 210 and a connecting rod 220, wherein the connecting head 210 is fixedly connected to the box body 100, and the connecting rod 220 is located on the side of the connecting head 210 facing away from the box body 100.

[0075] The driving assembly 500 defines a connecting hole 530 , and the connecting rod 220 passes through the connecting hole 530 .

[0076] Illustratively, the connector 210 is bonded to the box body 100 .

[0077] Exemplarily, the connecting rod 220 is a rubber rod so that the connecting rod 220 has a certain elastic deformation ability. After the connecting rod 220 is passed through the connecting hole 530, the connecting rod 220 is in a state of compression deformation (the connecting rod 220 and the connecting hole 530 are interference fit) to ensure that the connecting rod 220 can be stably fixed in the connecting hole 530.

[0078] By adopting the above technical solution, by setting a connecting head 210 and a connecting rod 220, the box body 100 is connected to the connecting head 210, and the connecting rod 220 is inserted into the connecting hole 530 on the drive assembly 500, so that the connecting device 200 is used to connect the box body 100 and the drive assembly 500.

[0079] Furthermore, in some embodiments of the present application, the connecting device is integrally formed with the box body 100 .

[0080] Illustratively, the connecting rod 220 is integrally formed with the box body 100 .

[0081] For example, the connecting rod 220 and the box body 100 are both made of plastic. When producing the wire protection box, the connecting rod 220 and the box body 100 are injection molded as one piece, which reduces production costs and reduces its material cost compared to an iron wire protection box. In addition, the structural strength of the wire protection box can be improved, thereby improving the installation stability of the wire protection box and the power harness 400 on the drive assembly 500.

[0082] By adopting the above technical solution, the production cost of the wire protection box is reduced.

[0083] Further, in some embodiments of the present application, reference is made to Figure 1 and Figure 3 The connecting rod 220 is provided with an anti-slip hook 221 , and the anti-slip hook 221 is a plurality of anti-slip hooks 221 distributed along the axial direction of the connecting rod 220 .

[0084] The anti-slip hooks 221 include: a guide surface and an anti-slip surface. The guide surface is located on the side of the anti-slip surface facing away from the connecting head 210. The outer diameter of the guide surface gradually increases along the axial direction of the connecting rod 220 and toward the connecting head 210. The anti-slip surface is perpendicular to the axial direction of the connecting rod 220.

[0085] Exemplarily, the connecting rod 220 is made of plastic, and the anti-slip barb 221 is integrally formed on the connecting rod 220 to ensure that the connecting rod 220 has a certain anti-rotation performance.

[0086] Exemplarily, the guide surface is an arc surface and the anti-slip surface is a plane, so that the anti-slip hook 221 is a cone-shaped as a whole; when the connecting rod 220 is inserted into the connecting hole 530, the guide surface facilitates the insertion of the connecting rod 220 into the connecting hole 530, and the anti-slip surface abuts against the inner wall of the connecting hole 530.

[0087] Illustratively, an extrusion groove 222 is formed on the peripheral wall of the connecting rod 220 along its axial direction. The extrusion groove 222 penetrates the anti-slip hook 221 . When the connecting rod 220 is inserted into the connecting hole 530 , the connecting rod 220 is deformed along the extrusion groove 222 .

[0088] By adopting the above technical solution and providing the anti-slip hook 221 , the firmness of the connecting rod 220 inserted into the connecting hole 530 is improved.

[0089] refer to Figure 7 , an embodiment of the present application also provides a power system, including: a drive assembly 500 and a power harness 400.

[0090] The outer surface of the drive assembly 500 includes a first step surface 510 and a second step surface 520. The first step surface 510 and the second step surface 520 are distributed along a first direction. The first step surface 510 is provided with a wiring harness connector 210, and the second step surface 520 is provided with a connecting and matching structure.

[0091] The power harness 400 includes a harness body and a harness plug. The harness plug is provided at one end of the harness body and connected to the harness connector.

[0092] In any of the wire protection boxes in the above embodiments, the wire harness body is fixed to the wire harness fixing surface 121 via the wire harness fixing member 300 , and the wire protection box is connected to the connecting and matching structure via the connecting device 200 .

[0093] By adopting the above technical solution, when the power harness 400 is installed on the drive assembly 500, the power harness 400 is first fixed on the harness fixing surface 121 through a fixed narrow band, and then the wire protection box is fixed on the second step surface 520 of the drive assembly 500 through the connecting device 200 and the connecting matching structure. At this time, the harness plug of the power harness 400 is facing the harness connector on the first step surface 510, and finally the harness plug is connected to the harness connector.
