[0010] In some optional embodiments, the wire harness fixing piece is provided with a plurality of buffer holes, and the plurality of buffer holes are sequentially arranged at intervals on the periphery of the wire through hole.

[0011] In some optional embodiments, two ends of the buffer hole pass through the two end walls respectively; or / and the aperture of the buffer hole is smaller than the aperture of the wire through hole.

[0012] Among them, in some optional embodiments, the wire harness fixing piece is used to cooperate with the tightening piece, and the tightening piece is used to be wrapped around the outer peripheral wall; the wire harness fixing piece also includes two limiting parts, and the two limiting parts are respectively connected to the two ends of the outer peripheral wall. The limiting parts protrude relative to the outer peripheral wall so that the two limiting parts are relatively spaced apart, and a space for accommodating the tightening piece is formed between the two limiting parts.

[0013] Among them, in some optional embodiments, the wiring harness fixing part also includes a partition part, which is connected to the outer peripheral wall and protrudes relative to the outer peripheral wall, and the partition part is located between the two limiting parts and is spaced apart from the two limiting parts respectively; when at least two tightening parts are wrapped around the wiring harness fixing part, the partition part is used to separate two adjacent tightening parts.

[0014] In some optional embodiments, the wire harness fixing member is an elastic structure, and under the action of external force along the radial direction of the wire through hole, the radial dimension of the wire through hole and / or the width dimension of the embedded channel portion can be reduced.

[0015] In the second aspect, the present application provides a wiring harness assembly, which includes a mounting member, at least two wiring harnesses and the above-mentioned wiring harness fixing member, the at least two wiring harnesses and the at least two wire through holes are arranged in a one-to-one correspondence, and each wiring harness is passed through a corresponding wire through hole; the mounting member is connected to the wiring harness fixing member and is used to connect the wiring harness fixing member to an external device.

[0016] On the third aspect, the present application provides a transport vehicle, which includes a vehicle body, a vibration source, electrical components and the above-mentioned wiring harness assembly.

[0017] The present application provides a wiring harness fixture having a columnar structure, comprising a circumferential outer wall and two end walls, the two end walls being connected to the ends of the outer wall. In this embodiment, the wiring harness fixture comprises an embedded channel portion and a wire passageway for passing multiple wires. The ends of the wire passageway extend through the two end walls, respectively. The wire passageway comprises at least two wire passage holes, each of which extends through both end walls. The embedded channel portion has a large degree of ductility. In the axial direction of the wiring harness fixture, the embedded channel portion extends through the two end walls, and in the radial direction of the wiring harness fixture, the embedded channel portion extends through the outer wall. It should be noted that in this embodiment, the radial direction of the wiring harness fixture refers to a direction perpendicular to the axial direction of the wiring harness fixture. The wire passageway further comprises two connecting channel portions, each corresponding to the two wire passage holes. Each wire passage hole communicates with the embedded channel portion via a corresponding connecting channel portion, i.e., a connecting channel portion is provided between the connecting opening and each wire passage hole.

[0018] Therefore, in this embodiment, a connecting channel portion is added between each wire through hole and the embedded channel portion, which can extend the distance between the embedded port and the wire through hole, increase the difficulty of the wire harness sliding out of the wire through hole, the connecting channel portion and the embedded channel portion due to external vibration or external pulling, avoid the wire harness from being separated from the wire harness fixture, and ensure the restraining effect of the wire harness fixture on multiple wire harnesses. In this embodiment, the direction from the embedded port to the connecting port defines the extension direction of the embedded channel portion, and the two ports of the connecting channel portion that are respectively connected to the embedded channel portion and the corresponding wire through hole define the extension direction of the connecting channel portion. In this embodiment, one embedded channel portion is connected to at least two connecting channel portions, so there is at least one connecting channel portion whose extension direction does not coincide with the extension direction of the embedded channel portion. Overall, the difficulty of the wire harness sliding out of the wire through hole, the connecting channel portion and the embedded channel portion is increased, the probability of the wire harness being separated from the wire harness fixture is greatly reduced, and the stability of the matching relationship between the wire harness and the wire harness fixture is improved.

[0019] When assembling a wiring harness and a wiring harness fixture, multiple wiring harnesses need to be sequentially embedded in the embedded channel portion, the corresponding connecting channel portion, and the wire through hole. When disassembling the wiring harness and the wiring harness fixture, multiple wiring harnesses need to be sequentially moved out of the wire through channel to separate from the wiring harness fixture. If a wiring harness that is farther from the connecting port is disassembled first, the wiring harness needs to overcome the elastic resistance of the wiring harness fixture, the friction resistance between the wiring harness and the wiring harness fixture, and the resistance of other wiring harnesses to the cable. Therefore, it is more difficult to actively move the wiring harness out of the wire through channel, making the wiring harness relatively stable relative to the vehicle body.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 The present application provides a wiring harness fixture 30, a wiring harness assembly 100 including the wiring harness fixture 30, and a transport vehicle 1000 using the wiring harness assembly 100. The transport vehicle 1000 may be a van, a truck, etc. for transporting goods, or a car, etc. for commuting. In this embodiment, the transport vehicle 1000 includes a vehicle body 900, which forms the main structure of the transport vehicle 1000. The interior space of the vehicle body 900 is divided into multiple areas, such as a cockpit, a passenger compartment, or a cargo compartment. The transport vehicle 1000 also includes a vibration source 800, an electrical component 700, and a wiring harness assembly 100 arranged inside the vehicle body 900. The vibration source 800 refers to a component in the transport vehicle 1000 that can generate vibration, such as an engine, a motor, an air conditioner, a transmission, an inverter, etc. Such components will generate vibration during operation and transmit the vibration to other components. The electrical component 700 may include a power battery pack to provide power, and may also include a controller for controlling each component, each component operating under the control of the controller. In this embodiment, a wiring harness assembly 100 may be connected between the electrical components 700, between the vibration source 800, and between the vibration source 800 and the electrical component 700. The wiring harness assembly 100 can enable the flow of electrical energy and the transmission of signals between the two components at its two connection ends. In this embodiment, most of the components in the vibration source 800 and the electrical component 700, such as the engine, motor, transmission, power battery pack, etc., are located outside the cockpit and passenger compartment, but the air outlet of the air conditioner can be connected to the cockpit or passenger compartment, and the human-computer interaction console of the controller can be set inside the cockpit.

[0033] See also Figure 2In this embodiment, a wiring harness assembly 100 is used to transmit signals and electrical energy between components. Specifically, the wiring harness assembly 100 includes a wiring harness fixture 30 and multiple wiring harnesses 10. The wiring harness fixture 30 can store and organize the multiple wiring harnesses 10 between components to prevent tangling. The wiring harness 10 assembly also includes a mounting member 40. The wiring harness fixture 30 is connected to the mounting member 40, which is connected to an external device. In this embodiment, the external device can be a vehicle body 900, such as a housing or bracket of the vehicle body 900, to substantially securely connect the wiring harness 10 to the vehicle body 900. It can also be a component on the transport vehicle 1000 (such as a power battery pack, air conditioner, etc.). For example, depending on the extension of the wiring harness 10, a portion of the wiring harness 10 can be substantially securely connected to the component to prevent the wiring harness 10 from being too long. In this embodiment, the harness fixture 30 can secure multiple harnesses 10, keeping them approximately stationary relative to the vehicle body 900. During travel of the transport vehicle 1000, the harness fixture 30 can constrain the harnesses 10, preventing them from swinging and becoming tangled, disconnecting the harnesses 10 from components, and preventing tangling that could cause a short circuit within the transport vehicle 1000. In this embodiment, the harness 10 can be coupled with multiple harness fixtures 30, which are sequentially spaced along the extension direction of the harness 10. In this embodiment, the harness fixture 30 is an elastic structure. In practical applications, the harness fixture 30 can buffer vibrations generated by the vibration source 800 and the vehicle body 900, preventing the harness 10 from becoming disconnected from components due to high vibration frequencies and amplitudes. Furthermore, the harness fixture 30 can reduce noise, vibration, and harshness generated during travel, thereby improving the ride comfort of the transport vehicle 1000.

[0034] See also Figure 3 The embodiment of the present application provides a wire harness fixture 30. The wire harness fixture 30 has a columnar structure and includes an outer peripheral wall 31 and two end walls 32. The outer peripheral wall 31 is arranged in a surrounding manner, and the two end walls 32 are respectively connected to the two ends of the outer peripheral wall 31. The direction in which the center point of one end wall 32 points to the center point of the other end wall 32 is roughly the axial direction of the wire harness fixture 30. In this embodiment, the wire harness fixture 30 is provided with a wire passage 33 for multiple wire harnesses 10 to pass through. The two ends of the wire passage 33 respectively pass through the two end walls 32. Multiple wire harnesses 10 are roughly passed through the wire passage 33 along the axial direction of the wire harness fixture 30, which can make the multiple wire harnesses 10 arranged more neatly to avoid entanglement. The wire harness fixture 30 is wrapped around the outer periphery of each wire harness 10, which can protect the wire harness 10 and buffer vibration for the wire harness 10.

[0035] See also Figure 4Specifically, the wire-passing channel 33 in this embodiment includes at least two wire-passing through-holes 333, each of which passes through the two end walls 32. The wire harness 10 is passed through a corresponding wire-passing through-hole 333, so that the wire harness 10 can be in a state of passing through the wire harness fixture 30. In actual application scenarios, the wire harness 10 is connected between components. Therefore, the wire-passing channel 33 in this embodiment includes an embedded channel portion 331 formed on the peripheral structure of the wire harness fixture 30. One end of the embedded channel portion 331 passes through the peripheral wall 31 and is defined as an embedded port 3311, and the other end is defined as a communication port 3312 and is respectively connected to the at least two wire-passing through-holes 333. The embedded channel portion 331 is roughly a gap formed on the wire harness fixture 30. This gap is the only way for the wire harness 10 to be embedded in the wire-passing through-hole 333. The embedded channel portion 331 has a large degree of extension. In the axial direction of the wiring harness fixture 30, the embedded channel portion 331 extends through both end walls 32, and in the radial direction of the wiring harness fixture 30, the embedded channel portion 331 extends through the outer peripheral wall 31. It should be noted that in this embodiment, the radial direction of the wiring harness fixture 30 refers to a direction perpendicular to the axial direction of the wiring harness fixture 30. Therefore, in this embodiment, the wiring harness 10 does not need to be separated from the assembly. The wiring harness 10 can be directly embedded into the corresponding wire through-hole 333 through the embedded opening 3311 formed in the outer peripheral wall 31 of the embedded channel portion 331, resulting in a relatively simple assembly and easy operation.

[0036] In some embodiments, the wire-passing through hole 333 can be directly connected to the communication port 3312 of the embedded channel portion 331, that is, the communication port 3312 directly penetrates the wall of the wire-passing through hole 333. In this embodiment, the wire-passing channel 33 further includes two communication channel portions 332, which are provided in a one-to-one correspondence with the two wire-passing through holes 333. Each wire-passing through hole 333 is connected to the embedded channel portion 331 via a corresponding communication channel portion 332, that is, a communication channel portion 332 is additionally provided between the communication port 3312 and each wire-passing through hole 333.

[0037] In summary, in this embodiment, a connecting channel portion 332 is additionally provided between each wire through hole 333 and the embedded channel portion 331, which can extend the distance between the embedded opening 3311 and the wire through hole 333, increase the difficulty for the wire harness 10 to slide out of the wire through hole 333, the connecting channel portion 332 and the embedded channel portion 331 due to external vibration or external pulling, avoid the wire harness 10 from being separated from the wire harness fixing part 30, and ensure the restraining effect of the wire harness fixing part 30 on multiple wire harnesses 10.

[0038] In this embodiment, the direction from the embedded opening 3311 to the connecting opening 3312 defines the extension direction of the embedded channel portion 331, and the two ports of the connecting channel portion 332 respectively connected to the embedded channel portion 331 and the corresponding wire through hole 333 define the extension direction of the connecting channel portion 332. In this embodiment, one embedded channel portion 331 is connected to at least two connecting channel portions 332, so there is at least one connecting channel portion 332 whose extension direction does not coincide with the extension direction of the embedded channel portion 331, which increases the difficulty of the wiring harness 10 slipping off from the wire through hole 333, the connecting channel portion 332 and the embedded channel portion 331 as a whole, greatly reduces the probability of the wiring harness 10 being fixed and separated from the wiring harness 10, and improves the stability of the matching relationship between the wiring harness 10 and the wiring harness fixing part 30.

[0039] In the process of embedding multiple wire harnesses 10 into the wire through holes 333 on the wire harness fixture 30, the multiple wire harnesses 10 need to be embedded in the embedding channel portion 331, the corresponding connecting channel portion 332 and the corresponding wire through holes 333 in sequence. When the wire harnesses 10 and the wire harness fixture 30 are disassembled, the multiple wire harnesses 10 need to be moved out of the wire through channels 33 in sequence to separate from the wire harness fixture 30. If a wire harness 10 that is farther away from the connecting port 3312 is disassembled first, the wire harness 10 needs to overcome the elastic resistance of the wire harness fixture 30, the friction resistance between the wire harness 10 and the wire harness fixture 30, and the resistance of other wire harnesses 10 to the cable. Therefore, it is more difficult for the wire harness 10 to actively move out of the wire through channels 33, making the state of the wire harness 10 relative to the vehicle body 900 relatively stable.

[0040] See also Figure 4 and Figure 5 It should be noted that in this embodiment, the embedded channel portion 331 and the communicating channel portion 332 are generally linear channels. Therefore, the extending direction of the embedded channel portion 331 in this embodiment is generally the direction from the embedded opening 3311 to the communicating opening 3312, and the extending direction of the communicating channel portion 332 is generally the direction from one end to the other. In other embodiments, the contour of the space between the two ends of the embedded channel portion 331 or the communicating channel portion 332 may be S-shaped, C-shaped, or other shapes. In such embodiments, the extending direction of the embedded channel portion 331 or the communicating channel portion 332 is specifically defined by the shape of the spatial contour and cannot be simply understood as the direction from one end to the other.

[0041] In this embodiment, the direction in which the embedded channel portion 331 extends is defined as a first extension direction, that is, the direction from the embedded opening 3311 toward the communicating channel portion 332 (the communicating opening 3312). The direction in which the communicating channel portion 332 extends is defined as a second extension direction, that is, the direction from the embedded channel portion 331 (the communicating opening 3312) toward the wire passage hole 333. In this embodiment, the first and second extension directions intersect, ensuring that the movement path formed by the wire passage hole 333, the communicating channel portion 332, and the embedded channel portion 331 includes at least one turning point, making it more difficult for the wiring harness 10 to exit the wire passage 33.

[0042] In this embodiment, the angle β between the first extension direction and the second extension direction is greater than 0° and less than or equal to 180° (the angle range here refers to the angle between the two directions). In this embodiment, at least two communicating channel portions 332 communicate with the embedded channel portion 331 via the communication opening 3312. The extension directions of any two of the at least two communicating channel portions 332 can have various relationships. In other embodiments, a communicating channel portion 332 communicates with the embedded channel portion 331 via the embedded channel portion 331 at a location between the embedding opening 3311 and the communication opening 3312.

[0043] In an embodiment in which at least two communicating channel portions 332 are connected to the embedded channel portion 331 through the communicating opening 3312, there is a first example, in which the second extension directions of any two communicating channel portions 332 intersect, the opening formed by the two communicating channel portions 332 faces away from the embedded channel portion 331, and the angle β between the second extension direction and the first extension direction is an acute angle, so that the two communicating channel portions 332 and the embedded channel portion 331 form a "Y"-shaped channel, so that the communicating channel portion 332 has a certain guiding effect, which is convenient for embedding the wiring harness 10 into the corresponding wire through hole 333; the opening formed by the two communicating channel portions 332 can face the embedded channel portion 331, and the angle β between the second extension direction and the first extension direction is an obtuse angle (not shown in the figure), so that the bending degree between the communicating channel portion 332 and the embedded channel portion 331 is greater, increasing the difficulty of moving the wiring harness 10 from the communicating channel portion 332 to the embedded channel portion 331.

[0044] In this embodiment, the number of the wire through holes 333 and the connecting channel portions 332 are both two, and the angle β between the first extension direction and the second extension direction is limited to greater than 0° and less than 90°, so that the two connecting channel portions 332 and the embedded channel portion 331 can form a "Y"-shaped channel, so as to facilitate the wiring harness 10 to be easily embedded into the corresponding wire through hole 333 under the guiding action of the connecting channel portion 332.

[0045] See also Figure 6There is also a second example in which the second extension directions of any two communicating channel portions 332 are opposite, and the two communicating channel portions 332 form a "T"-shaped space. In this embodiment, the second extension direction is perpendicular to the first extension direction, that is, the extension direction of each communicating channel portion 332 is perpendicular to the extension direction of the embedded channel portion 331. This allows the two communicating channel portions 332 and the embedded channel portion 331 to form a "T"-shaped channel, thereby increasing the degree of bending between the communicating channel portion 332 and the embedded channel portion 331 and making it more difficult for the wiring harness 10 to move from the communicating channel portion 332 to the embedded channel portion 331. In other embodiments, none of the two communicating channel portions 332 are perpendicular to the embedded channel portion 331, and the angle between the extension direction of one communicating channel portion 332 and the first extension direction is complementary to the angle between the extension direction of the other communicating channel portion 332 and the first extension direction. This also allows the two communicating channel portions 332 to extend in opposite directions.

[0046] See also Figure 7 In an embodiment where a communication channel portion 332 communicates with the embedded channel portion 331 via the embedded channel portion 331 at a position between the embedded opening 3311 and the communication opening 3312, the second extension directions of any two communication channel portions 332 can be parallel, that is, the two communication channel portions 332 are located to the left or right of the embedded channel portion 331 in its extension direction, and the angle between the second extension direction and the first extension direction of the two communication channel portions 332 is the same, so that one embedded channel portion 331 can cooperate with multiple communication channel portions 332. When one embedded channel portion 331 communicates with three, four, or more communication channel portions 332, this arrangement of the embodiment can avoid a thin structure between two adjacent communication channel portions 332, ensuring a certain strength between the two adjacent communication channel portions 332, effectively limiting the movement of the wire harness 10 and effectively buffering vibration transmitted from the outside to the wire harness fixture 30.

[0047] See also Figure 4 、 Figure 5 and Figure 6In this embodiment, at least two wire-passing through-holes 333 are arranged in parallel, that is, the axes of each wire-passing through-hole 333 are parallel, and the relationship between the axes of the wire-passing through-holes 333 and the wiring harness fixture 30 can be arranged in a variety of ways. In this embodiment, the axes of the wire-passing through-holes 333 are parallel to the axis of the wiring harness fixture 30, and the two wire-passing through-holes 333 are spaced apart. The radial direction of each wire-passing through-hole 333 is perpendicular to the axial direction of the wiring harness fixture 30, and the first extension direction is perpendicular to the axial direction of the wiring harness fixture 30. In this embodiment, each wire-passing through-hole 333 has multiple radial directions, and each wire-passing through-hole 333 has a radial direction parallel to the first extension direction, but no radial direction coincides with the first extension direction, that is, the first extension direction does not coincide with the radial direction of any wire-passing through-hole 333. In other embodiments, the axial direction of the wire through hole 333 intersects with the axial direction of the wire harness fixing member 30, that is, each wire through hole 333 has two ports, and the two ports of the wire through hole 333 are respectively formed on the two end walls 32, and in the axial direction of the wire fixing member, the two ports of the wire through hole 333 are staggered.

[0048] In this embodiment, the wiring harness fixture 30 is an elastic structure with elastic deformation capabilities. Specifically, in this embodiment, the wiring harness fixture 30 is a rubber, silicone, or plastic structure, and is formed by reverse molding, injection molding, or other methods to provide elastic deformation capabilities. In other embodiments, the wiring harness fixture 30 can be made of a non-elastic material, such as metal (copper alloy, stainless steel, etc.) or plastic. The non-elastic material can be bent or formed into a curved shape to provide the entire wiring harness fixture 30 with elastic deformation capabilities.

[0049] In this embodiment, the wiring harness fixture 30 is used with a wiring harness 10. The wiring harness 10 typically comprises a copper or aluminum core wrapped in rubber, and the outer circumference of the wiring harness 10 is generally cylindrical. In this embodiment, when no external force is applied, the width of the embedded channel portion 331 is smaller than the radial dimension of the wiring harness 10. It should be noted that the embedded channel portion 331 has a width direction that is perpendicular to the first extension direction and the axial direction of the wiring harness fixture 30. The width of the embedded channel portion 331 is the dimension of the embedded channel portion 331 in this width direction. In this embodiment, when no external force is applied, the width of the connecting channel portion 332 is smaller than the radial dimension of the wiring harness 10. It should be noted that the connecting channel portion 332 has a width direction that is perpendicular to the second extension direction and the axial direction of the wiring harness fixture 30. The width of the connecting channel portion 332 is the dimension of the connecting channel portion 332 in this width direction.

[0050] In this embodiment, the wire harness 10 is squeezed by the wire harness fixture 30 during the process of mating with the embedded channel portion 331 and the connecting channel portion 332. Specifically, during assembly or separation of the wire harness fixture 30 and the wire harness 10, the wire harness fixture 30 deforms and generates an elastic force, which is applied to the wire harness 10 to tighten the wire harness 10. This embodiment significantly increases the difficulty of the wire harness 10 automatically moving out of the wire passage 33 under the influence of non-human external forces, thereby reducing the probability of the wire harness 10 separating from the wire harness fixture 30. In this embodiment, the connecting channel portion 332 provides a certain guiding function, allowing the width of the connecting channel portion 332 to be smaller than the width of the embedded channel portion 331. This guiding function of the connecting channel portion 332 overcomes the difficulty of assembly caused by its smaller size and significantly increases the difficulty of the wire harness 10 automatically embedding into the connecting channel portion 332 under the influence of non-human external forces.

[0051] In this embodiment, when no external force is applied to the wire through-hole 333, the radial dimension of the wire through-hole 333 is equal to or less than the radial dimension of the wiring harness 10. In this embodiment, when the wiring harness 10 is passed through the wire through-hole 333, friction exists between the hole wall of the wire through-hole 333 and the outer peripheral side surface of the wiring harness 10, or the wiring harness fixture 30 applies a certain elastic force to the wiring harness 10, which can limit the axial movement of the wiring harness 10 relative to the wiring harness fixture 30 along the wiring harness fixture 30, thereby stabilizing the mating relationship between the wiring harness 10 and the wiring harness fixture 30. In this embodiment, the width of the embedded channel portion 331, the width of the connecting channel portion 332, and the radial dimension of the wire through-hole 333 are set according to the dimensions of the wiring harness 10, and this embodiment does not provide an example.

[0052] See also Figure 8 In this embodiment, the wiring harness fixture 30 may include multiple wire passages 33, which are spaced apart from each other. In this embodiment, the size and shape of each wire passage 33 may vary to accommodate wiring harnesses 10 of varying sizes. For example, the extension direction of the wire through hole 333, the width of the embedded channel portion 331, and the width of the connecting channel portion 332 may all vary, and these are not listed here.

[0053] See also Figure 3 and Figure 4In this embodiment, the wiring harness fixture 30 is further provided with a plurality of buffer holes 34, which are sequentially arranged at intervals around the periphery of the wire through hole 333. In this embodiment, the plurality of wire through holes 333 are provided in a designated area on the wiring harness fixture 30, and the plurality of buffer holes 34 are arranged around the periphery of the designated area. In other embodiments, each wire through hole 333 is provided with a plurality of buffer holes 34 around its periphery. In this embodiment, the buffer holes 34 are through-holes, extending through both end walls 32. In this embodiment, the inner diameter of the through-hole buffer holes 34 is smaller than that of the wire through hole 333, and is less than or equal to half the inner diameter of the wire through hole 333. For example, in this application, the inner diameter of the wire through hole 333 is 10 mm, and the inner diameter of the buffer holes 34 is less than or equal to 5 mm. In another example, in this application, the inner diameter of the wire through hole 333 is 16 mm, and the inner diameter of the buffer holes 34 is less than or equal to 8 mm. In other embodiments, the buffer hole 34 may be a bubble-shaped cavity hidden in the wiring harness fixing component 30 ; the buffer hole 34 may also be a blind hole opened on the two end walls 32 .

[0054] See also Figure 9 In this embodiment, the wiring harness fixture 30 further includes two stoppers 35, each connected to the outer peripheral wall 31 at either end in the axial direction of the wiring harness fixture 30. The stoppers 35 protrude radially from the outer peripheral wall 31 in the wiring harness fixture 30. In this embodiment, the radial direction of the wiring harness fixture 30 refers to a direction perpendicular to the axial direction of the wiring harness fixture 30. In this embodiment, the wiring harness assembly 100 further includes a tightening member 20. The tightening member 20 is a belt-like structure, with its two ends capable of overlapping to form a hoop or ring structure. The tightening member 20 is disposed around the outer peripheral wall 31. When the tightening member 20 forms an annular structure, the size of the ring opening can be adjusted to apply external force to the wire harness fixture 30. When the wire harness fixture 30 is subjected to external force, the hole wall of the wire through hole 333 has a greater clamping force on the wire harness 10, and the friction between the hole wall of the wire through hole 333 and the outer peripheral side of the wire harness 10 is greater. The width of the embedded channel portion 331 and the size of the connecting channel portion 332 are reduced to varying degrees, so that the structure formed by the wire harness fixture 30 and the wire harness 10 is more stable, and the difficulty of the wire harness 10 automatically passing through the wire channel 33 under the action of non-human external force is increased. In actual application scenarios, the limit portions 35 at both ends of the wire harness fixture 30 can form a space for accommodating the tightening member 20. The limit portions 35 can limit the annular tightening member 20 from slipping off the outer peripheral wall 31 at one end of the wire harness fixture 30, ensuring the stability of the matching relationship between the wire harness fixture 30 and the tightening member 20.

[0055] In this embodiment, the limiting portion 35 is an annular structure with a notch and is disposed around the outer wall 31 to enhance the limiting effect of the limiting portion 35 on the tightening member 20. The reserved notch is connected to the embedded channel portion 331. In this embodiment, the protruding height of the limiting portion 35 relative to the outer wall 31 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc. During the production of the harness fixture 30, the protruding height of the limiting portion 35 relative to the outer wall 31 can be set according to the size of the tightening member 20 that cooperates with the harness fixture 30. For example, the protruding height of the limiting portion 35 relative to the outer wall 31 can be set to be greater than or equal to the protruding height of the tightening member 20 relative to the outer wall 31 to prevent the tightening member 20 from slipping due to the smaller size of the limiting portion 35.

[0056] In this embodiment, the wiring harness fixture 30 further includes at least one partition 36, which is connected to the outer peripheral wall 31 and protrudes relative to the outer peripheral wall 31. The partition 36 is located between the two limiting portions 35. When at least two tightening members 20 are arranged around the wiring harness fixture 30, two adjacent tightening members 20 are distributed on both sides of the partition 36 to prevent at least two tightening members 20 from sliding to one end of the wiring harness fixture 30, thereby preventing uneven force on the wiring harness fixture 30. In this embodiment, the partition 36 is a convex block structure and is arranged on the side of the outer peripheral wall 31 away from the embedded channel. In some embodiments, there can be multiple partitions 36, and the multiple partitions 36 are arranged in sequence along the axial direction of the lower wiring harness fixture 30. In this embodiment, the various parts of the wiring harness fixture 30 in the axial direction of the wiring harness fixture 30 can be subjected to uniform force, so that the cable is stably fixed. In other embodiments, the shape of the partition 36 can refer to the shape of the limiting portion 35 described above, that is, the partition 36 is an annular structure with a notch. In this embodiment, the protrusion height of the partition 36 relative to the outer peripheral wall 31 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc. During the production of the harness fixture 30, the protrusion height of the partition 36 relative to the outer peripheral wall 31 can be set according to the size of the tightening member 20 that cooperates with the harness fixture 30. For example, the protrusion height of the partition 36 relative to the outer peripheral wall 31 can be set to be greater than or equal to the protrusion height of the tightening member 20 relative to the outer peripheral wall 31 to prevent the tightening member 20 from slipping due to the smaller size of the partition 36.

[0057] The present embodiment provides a wiring harness fixture 30. The wiring harness fixture 30 has a columnar structure and includes a surrounding outer wall 31 and two end walls 32, with the two end walls 32 connected to the ends of the outer wall 31. In this embodiment, the wiring harness fixture 30 is provided with an embedded channel portion 331 and a wire passage 33 for passing multiple wires 10. The ends of the wire passage 33 respectively penetrate the two end walls 32. The wire passage 33 includes at least two wire through holes 333, each of which penetrates the two end walls 32. The embedded channel portion 331 has a large degree of extensibility. In the axial direction of the wiring harness fixture 30, the embedded channel portion 331 penetrates the two end walls 32. In the radial direction of the wiring harness fixture 30, the embedded channel portion 331 penetrates the outer wall 31. It should be noted that the radial direction of the wiring harness fixture 30 in this embodiment refers to the direction perpendicular to the axial direction of the wiring harness fixture 30. The wire passing channel 33 also includes two connecting channel portions 332, which are arranged in one-to-one correspondence with the two wire passing through holes 333. Each wire passing through hole 333 is connected to the embedded channel portion 331 via a corresponding connecting channel portion 332, that is, a connecting channel portion 332 is additionally provided between the connecting port 3312 and each wire passing through hole 333.

[0058] Therefore, in this embodiment, a connecting channel portion 332 is additionally provided between each wire through hole 333 and the embedded channel portion 331, which can extend the distance between the embedded opening 3311 and the wire through hole 333, increase the difficulty for the wire harness 10 to slide out of the wire through hole 333, the connecting channel portion 332 and the embedded channel portion 331 due to external vibration or external pulling, avoid the wire harness 10 from being separated from the wire harness fixing member 30, and ensure the restraining effect of the wire harness fixing member 30 on multiple wire harnesses 10. In this embodiment, the direction from the embedded opening 3311 to the connecting opening 3312 defines the extension direction of the embedded channel portion 331, and the two ports of the connecting channel portion 332, which are respectively connected to the embedded channel portion 331 and the corresponding wire through hole 333, define the extension direction of the connecting channel portion 332. In this embodiment, one embedded channel portion 331 is connected to at least two connecting channel portions 332, so there is at least one connecting channel portion 332 whose extension direction does not coincide with the extension direction of the embedded channel portion 331, which increases the difficulty of the wiring harness 10 slipping off from the wire through hole 333, the connecting channel portion 332 and the embedded channel portion 331 as a whole, greatly reduces the probability of the wiring harness 10 being fixed and separated from the wiring harness 10, and improves the stability of the matching relationship between the wiring harness 10 and the wiring harness fixing part 30.

[0059] In the actual assembly of the wiring harness 10 and the wiring harness fixture 30, multiple wiring harnesses 10 need to be sequentially embedded in the embedded channel portion 331, the corresponding connecting channel portion 332, and the wire through hole 333. In the case of disassembling the wiring harness 10 and the wiring harness fixture 30, multiple wiring harnesses 10 need to be sequentially moved out of the wire through channel 33 to separate from the wiring harness fixture 30. If a wiring harness 10 that is farther away from the connecting port 3312 is disassembled first, the wiring harness 10 needs to overcome the elastic resistance of the wiring harness fixture 30, the friction resistance between the wiring harness 10 and the wiring harness fixture 30, and the resistance of other wiring harnesses 10 to the cable. Therefore, it is more difficult for the wiring harness 10 to actively move out of the wire through channel 33, making the wiring harness 10 relatively stable relative to the vehicle body 900.
