[0031] According to the inventor, when a car is in motion, factors such as road conditions, vibrations in the power system, and body vibrations can cause the car's charging harness to shake or be pulled, which not only poses a risk of cutting the wires but also exacerbates wear and tear on the charging harness, thus compromising the car's safety.

[0032] To address the instability issues of charging harnesses in actual vehicles, it is necessary to improve or optimize existing technologies.

[0033] Example 1

[0034] Please see Figure 1 The first aspect of this utility model provides a wire harness fixing structure 1 for fixing a charging wire harness 2, installed between the power battery and the charging port of a car, to the side panel of the car body. It is worth noting that the charging wire harness 2 referred to here is a cable with a voltage range covering 200V~1500V, such as a cable with a working voltage of 400V or a wire diameter of 10mm. 2 The cables, including but not limited to fast charging cables and slow charging cables, are generally connected to adjacent components (such as the power battery and charging station) via fast plugs to achieve energy storage and conversion. The power battery mentioned here refers to the battery that provides power to the vehicle, such as ternary lithium batteries, lithium iron phosphate batteries, lithium titanate batteries, and lead-acid batteries. The vehicle side panels refer to the surrounding structure of the vehicle body, including A-pillars, doors, windows, and lights, primarily used to protect occupants and prevent the vehicle interior from being affected by the external environment.

[0035] For example, such as Figure 2 , Figure 3As shown, the wiring harness fixing structure 1 includes a protective plate 11 and a cover plate 12. The protective plate 11 is mounted on the charging wiring harness 2 to protect it. The cover plate 12 is detachably connected to the protective plate 11 (e.g., plug-in connection, snap-fit ​​connection, etc.) to cover the protective plate 11. Specifically, the protective plate 11 includes a protective plate body 111, a first connecting portion 112, and a second connecting portion 113. The protective plate body 111 is formed by a base plate 111a and two side plates 111b, which are connected by the base plate 111a. A wiring harness receiving area 11a is formed between the base plate 111a and the two side plates 111b, facing the cover plate 12. The wiring harness receiving area 11a extends along the extension direction (e.g., the length direction) of the protective plate body 111. Preferably, the protective plate body 111 has a U-shaped structure. The first connecting portion 112 and the second connecting portion 113 are formed on opposite sides of the protective plate body 111 for connection to the vehicle body side panel. Preferably, the shape of the protective plate body 111 matches the wiring direction (e.g., arc shape) of the charging cable harness 2. In this first embodiment, as shown... Figure 2 The guard plate 11 shown has a first connecting portion 112 formed on the right side of one end of the guard plate 11, and a second connecting portion 113 formed on the left side of the other end of the guard plate 11, but is not limited thereto. In this way, the guard plate 11 is connected to the vehicle side panel through two mounting points, the first connecting portion 112 and the second connecting portion 113, which helps to ensure the connection stability of the guard plate 11 on the vehicle side panel.

[0036] Furthermore, to facilitate the installation of the protective plate 11 on the vehicle side panel, one of the first connecting portion 112 and the second connecting portion 113 is provided with a waist hole 118, and the other of the first connecting portion 112 and the second connecting portion 113 is provided with a connecting hole 119. The waist hole 118 and the connecting hole 119 are used to engage with fastening elements (such as fastening bolts) to install the protective plate 11 on the vehicle side panel. In this embodiment, the waist hole 118 is formed on the first connecting portion 112, and the connecting hole 119 is formed on the second connecting portion 113. Thus, when the protective plate 11 is connected to the vehicle side panel, firstly, the waist hole 118 and the connecting hole 119 of the protective plate 11 are aligned one-to-one with the pre-reserved mounting holes of the vehicle side panel, and then the fastening elements are installed in the waist hole 118 and the corresponding pre-reserved mounting holes, and the connecting hole 119 and the corresponding pre-reserved mounting holes, thereby achieving the connection between the protective plate 11 and the vehicle side panel. It is worth mentioning that, since the guard plate 11 has waist holes 118, it is also convenient to adjust the connection between the first connecting part 112 and the side wall of the vehicle body in the length direction of the waist holes 118.

[0037] Furthermore, to improve the structural strength of the wire harness fixing structure 1, the protective plate 11 also includes several reinforcing portions. The reinforcing portion formed between the protective plate body 111 and the first connecting portion 112 can be referred to as the first reinforcing portion 115, and the reinforcing portion formed between the protective plate body 111 and the second connecting portion 113 can be referred to as the second reinforcing portion 116. Preferably, both the first reinforcing portion 115 and the second reinforcing portion 116 are rib-like or rib-like. In some embodiments, there can be multiple first reinforcing portions 115 and second reinforcing portions 116. In this first embodiment, there are two first reinforcing portions 115 and two reinforcing portions 116. The two first reinforcing portions 115 and the two second reinforcing portions 116 are arranged at a distance from each other.

[0038] Furthermore, such as Figure 3 As shown, the protective plate 11 also includes a transition portion 114. The second connecting portion 113 is connected to or integrally formed with the protective plate body 111 through the transition portion 114. To ensure the wiring harness 2's routing, preferably, the plane containing the second connecting portion 113 and the plane containing the first connecting portion 112 are coplanar, that is, the plane containing the upper outer surface of the second connecting portion 113 and the plane containing the upper outer surface of the first connecting portion 112 are at the same vertical height. Specifically, one end of the first connecting portion 112 is connected to or integrally formed with the protective plate body 111, and the other end extends outward from one side of the outer surface of the protective plate body 111 in a direction away from the protective plate body 111, such as in a direction perpendicular to the plane containing one side of the outer surface of the protective plate body 111. One end of the transition portion 114 is connected to or integrally formed with the edge of the protective plate body 111, and the other end extends outward in a direction away from the protective plate body 111 to connect with one end of the second connecting portion 113, such as in a direction parallel to the plane containing one side of the outer surface of the protective plate body 111. The other end of the second connecting portion 113, which is connected to the transition portion 114, also extends outward in a direction away from the main body 111 of the protective plate, such as in a direction perpendicular to the plane where the transition portion 114 is located. It is worth mentioning that the outward direction mentioned here is relative to the protective plate 11; that is, the direction closer to the protective plate 11 is inward, and the direction away from the protective plate 11 is outward.

[0039] Furthermore, to reduce the weight of the wire harness fixing structure 1, the protective plate 11 also includes several weight-reducing grooves. The weight-reducing groove formed on the first connecting portion 112 can be called the first weight-reducing groove, and the weight-reducing groove formed on the second connecting portion 113 can be called the second weight-reducing groove. Since there are multiple first and second weight-reducing grooves, one side of the first connecting portion 112 is hollowed out due to the first weight-reducing groove, and one side of the second connecting portion 113 is also hollowed out due to the second weight-reducing groove. This helps reduce the labor intensity of workers during assembly.

[0040] For example, such as Figures 2 to 4 As shown, to achieve a detachable connection between the guard plate 11 and the cover plate 12, the guard plate 11 further includes a retainer 117, and the cover plate includes a cover plate body 121 and a latch 122. The retainer 117 is formed on the side of the guard plate body 111, and the latch 122 is formed at the edge of the cover plate body 121. Specifically, the retainer 117 is formed by a left side plate 117a, a front side plate 117b, and a right side plate 117c. The front side plate 117b connects the left side plate 117a and the right side plate 117c, and is connected to the guard plate body 111 through the left side plate 117a and the right side plate 117c. A slot 117d is formed between the left side plate 117a, the front side plate 117b, the right side plate 117c, and the guard plate body 111, penetrating the retainer 117. One end of the latch 122 is connected to the edge of the cover plate body 121, and the other end extends downward in a hook shape away from the cover plate body 121. Thus, when the guard plate 11 and the cover plate 12 are connected, the cover plate 12 engages with the retaining seat 117 via the latch 122. Specifically, one end of the latch 122 engages in the retaining groove 117d of the retaining seat 117, and the hook-shaped structure at that end abuts against the lower bottom surface of the front side plate 117b of the retaining seat 117, thereby connecting the cover plate 12 and the guard plate 11. When it is necessary to separate the guard plate 11 and the cover plate 12, by overcoming the abutting force between the latch 122 and the retaining seat 117, and by pulling the latch 122 upward from the retaining groove 117d of the retaining seat 117, the cover plate 12 and the guard plate 11 can be separated. It is worth mentioning that when one end of the buckle 122 is inserted into the slot 117d of the card holder 117, and when the abutment force between the buckle 122 and the card holder 117 is overcome, the buckle 122 will undergo the required elastic deformation to achieve the snap-fit ​​connection or separation.

[0041] Furthermore, to increase the contact area between the latch 122 and the card holder 117, the front side plate 117b of the card holder 117 is wedge-shaped or tongue-shaped. Specifically, viewed vertically, the side of the front side plate 117b closest to the card groove 117d has a structure that slopes or protrudes into the card groove 117d, causing the card groove 117d to gradually taper from top to bottom. This helps to improve the contact effect between the latch 122 and the card holder 117.

[0042] Furthermore, to facilitate workers in overcoming the contact force between the buckle 122 and the card holder 117, the front side plate 117b of the card holder 117 is provided with a relief groove 117e. Specifically, viewed vertically, the relief groove 117e is formed on the side of the front side plate 117b away from the card slot 117d, and the opening of the relief groove 117e faces downward. Preferably, the relief groove 117e communicates with the card slot 117d. This allows workers to insert one end of a tool (such as a flathead screwdriver) into the card slot 117d through the relief groove 117e, and pry the front side plate 117b outward to a certain angle to overcome the contact force between the buckle 122 and the card holder 117, thereby separating the cover plate 12 and the protective plate 11.

[0043] In some embodiments, there may be multiple latches 122 and latch seats 117. In this first embodiment, there are six latches 122 and six latch seats 117. Three of the six latches 122 are formed on one side of the cover plate body 121, and the other three are formed on the other side of the cover plate body 121. Preferably, the three latches 122 formed on the same side of the cover plate body 121 are spaced apart along the extension direction of the cover plate 12. Correspondingly, the six latch seats 117 correspond one-to-one with the six latches 122, with three formed on one side of the guard plate body 111 and the other three formed on the other side of the guard plate body 111. Preferably, three of the six latch seats 117 are located on the same side of the guard plate body 111 as the first connecting portion 112, and the other three are located on the same side of the guard plate body 111 as the second connecting portion 113.

[0044] Furthermore, to overcome the problem of positional interference between the guard plate 11 and the cover plate 12 during assembly, the cover plate 12 also includes a clearance opening 123. The clearance opening 123 is formed on both sides of the cover plate body 121 and corresponds to the positions of the first connecting portion 112 and the second connecting portion 113. Thus, when the guard plate 11 and the cover plate 12 are connected, the clearance opening 123 on the cover plate 12 facilitates the passage of the first connecting portion 112, the second connecting portion 113, and their surrounding structures through the clearance opening 123, thereby achieving the assembly of the guard plate 11 and the cover plate 12. In some embodiments, there may be multiple clearance openings 123. In this first embodiment, there are two clearance openings 123. It is worth mentioning that one of these two clearance openings 123 is for the transition portion 114 of the guard plate 11 to pass through.

[0045] Preferably, when viewed from the side, the cover body 121 is arc-shaped, and the bending direction is the same as that of the protective plate body 111. This helps to solve the problem of the charging cable harness 2 easily shaking or being pulled.

[0046] Furthermore, according to the inventors, in order to ensure the protective effect of the wire harness fixing structure 1 on the charging wire harness 2, the chord length of the arc-shaped cover body 121 is 140mm~160mm (such as 140mm, 150mm, 160mm, etc.), and the radius is 83mm~85mm (such as 83mm, 84mm, 85mm, etc.).

[0047] Furthermore, the cover plate 11 also includes process holes 120. The process holes 120 are formed on the cover plate body 111. In some embodiments, there may be multiple process holes 120. In this first embodiment, there are six process holes 120. Three of these six process holes 120 are formed on one side of the cover plate body 121, and the other three are formed on the other side of the cover plate body 121. Preferably, the three process holes 120 formed on the same side of the cover plate body 121 are spaced apart along the extension direction of the cover plate 12. This is beneficial for weight reduction, water conduction, heat dissipation, etc.

The wiring harness fixing structure 1 is mounted on the charging wiring harness 2. Preferably, the wiring harness fixing structure 1 is fitted onto the bent portion or the middle section of the charging wiring harness 2. This is beneficial for giving the wiring harness assembly higher stability.
