Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a wire harness protection structure and an electric pedal. Background Art

[0002] In larger vehicles, due to their height, electric running boards are often required to enhance ingress and egress convenience. These electric running boards not only provide convenience but also contribute to the vehicle's luxurious and technological feel. Currently, mainstream electric running boards are categorized by function into two main types: non-illuminated and illuminated. Illuminated running boards, in particular, offer significant visual advantages over their non-illuminated counterparts, creating a more welcoming and comfortable riding environment. Consequently, illuminated running boards are becoming increasingly common in the market and are expected to become a mainstream trend in the future.

[0003] The key to the striking visual effect of illuminated running boards lies in the addition of ambient light strips to the running board body. These strips are controlled by dedicated ambient light wiring harnesses, enabling functions such as turning the lights on and off and adjusting the brightness. However, the current design of ambient light wiring harnesses for conventional illuminated electric running boards presents several issues. Specifically, these harnesses are often directly fixed to the exterior of the product, or even left suspended. This design approach presents three major problems.

[0004] The first problem is that the completely exposed wiring harness seriously affects the overall appearance of the product. The exposed wiring harness makes the originally beautifully designed electric step appear cluttered and disorganized, reducing its overall aesthetics and sense of class. The second problem is that once the wiring harness is secured with cable ties, its position cannot be adjusted again. This means that during the assembly process, any deviation from the wiring harness's position requires disassembly and reinstallation, which requires extremely high assembly precision and efficiency. This not only increases production costs but can also lead to quality issues during installation. The third problem is that the suspended portion of the wiring harness can easily become entangled with moving components such as the electric step's connecting rod. During the opening and closing of the step, these entangled wires may wear out, or even cause a short circuit or breakage, affecting the normal use of the electric step.

[0005] Furthermore, exposed wiring harnesses are susceptible to corrosion and degradation when exposed to external contaminants. Especially in humid, dusty, or corrosive environments, the wiring harness's insulation can become damaged, leading to short circuits or failure. This not only affects the proper functioning of the electric step but also poses a threat to the vehicle's overall safety. Therefore, solving the design challenge of ambient lighting wiring harnesses for illuminated electric step systems has become a pressing technical challenge. Utility Model Content

[0006] In view of this, the purpose of the present invention is to overcome the deficiencies in the related art. The present invention provides a wiring harness protection structure and an electric pedal.

[0007] The utility model provides the following technical solutions:

[0008] A wire harness protection structure is installed on a connecting rod of an electric pedal and comprises a fixing piece.

[0009] The fixing member has a docking groove, a clamping portion is provided on the fixing member, and a clamping groove corresponding to the clamping portion is provided on the connecting rod. The clamping portion is clamped and matched with the clamping groove. The docking groove and the side of the connecting rod are combined to form a threading channel, and the threading channel is used to thread the wiring harness.

[0010] As a further improvement of the above technical solution, clamping plates are symmetrically extended along the two edges of the opening of the docking groove in the direction approaching the connecting rod, and the opposite end faces of the two clamping plates are provided with clamping bosses; the two clamping plates are clamped on the connecting rod, and the clamping bosses are inserted into the corresponding clamping grooves, and the clamping plates and the clamping bosses together form the clamping part.

[0011] As a further improvement of the above technical solution, a guide surface is provided on the end surface of the clamping boss close to the connecting rod, and the guide surface is located on the side of the clamping boss away from the fixing member; the spacing between the two opposite guide surfaces gradually increases from the side close to the fixing member to the side away from the fixing member, and the maximum spacing between the two opposite guide surfaces is not less than the width of the connecting rod.

[0012] As a further improvement of the above technical solution, a plurality of the clamping portions are evenly distributed along the threading direction of the threading channel.

[0013] As a further improvement of the above technical solution, pre-tightening pads are respectively provided on the end surfaces of the two clamping plates close to the connecting rod.

[0014] As a further improvement of the above technical solution, a curved portion is extended from the end of the fixing member close to the pedal, and the engaging groove extends correspondingly in the curved portion.

[0015] As a further improvement of the above technical solution, an assembly hole is provided at a turning point between the fixing piece and the curved portion, and the assembly hole is communicated with the engaging groove.

[0016] As a further improvement of the above technical solution, a buffer pad is laid in the clamping groove and on the side of the connecting rod close to the clamping groove.

[0017] As a further improvement of the above technical solution, the fixing member is composed of a plurality of fixing segments spliced ​​together.

[0018] The present invention further provides an electric pedal, comprising a connecting rod and a wiring harness protection structure as described above, wherein the wiring harness protection structure is arranged on the connecting rod.

[0019] Compared with the related art, the beneficial effects of the present invention are:

[0020] The wiring harness protection structure provided by the present invention mainly solves the problem of how to effectively protect and manage the wiring harness when laying additional structures such as ambient light strips on the electric pedal. The specific operation process is as follows: first, the ambient light strip can be installed on the pedal of the electric pedal, and then the wiring harness of the electric pedal is laid along the direction of the connecting rod; after the wiring harness is laid, the clamping part of the fixing part is matched with the clamping groove on the connecting rod, so that the fixing part is clamped on the connecting rod. This clamping method is not only simple to operate, but also has a stable structure. At the same time, a tight wire threading channel is formed between the clamping groove and the connecting rod, which firmly encloses the wiring harness and effectively prevents the shaking and displacement of the wiring harness. The installation of the wiring harness protection structure not only achieves the precise fixation of the wiring harness position, but also provides solid protection for the wiring harness.

[0021] More importantly, this structure effectively prevents the wiring harness from hooking up with the connecting rod of the electric step due to being suspended in the air, greatly reducing the risk of wiring harness breakage. It also prevents the wiring harness from being easily exposed to contaminants, effectively improving the reliability and lifespan of the wiring harness.

[0022] Furthermore, the snap-fitting connection between the snap-fit ​​portion and the snap-fitting slot makes assembly and disassembly of the fixture extremely simple and quick. This significantly saves time and labor costs when maintaining or replacing the ambient light strip and wiring harness later, improving maintenance efficiency.

[0035] Example 1

[0036] Combine Figure 1 、 Figure 2 As shown, this embodiment provides a wire harness protection structure, which is installed on the connecting rod 110 of the electric pedal 100 and includes a fixing member 200 .

[0037] The fixing member 200 has a docking groove 210, and a clamping portion 220 is provided on the fixing member 200. The fixing member 200 is specifically a strip corresponding to the connecting rod 110, and the connecting rod 110 is provided with a clamping groove 111 corresponding to the clamping portion 220. The clamping portion 220 is clamped and matched with the clamping groove 111. The docking groove 210 and the side of the connecting rod 110 are combined to form a wire threading channel 201, and the wire threading channel 201 is used to thread the wiring harness 130.

[0038] The wiring harness protection structure provided in this embodiment can be used to install additional structures such as an ambient light strip on the electric pedal 100. First, the ambient light strip can be installed on the pedal 120 of the electric pedal 100. Then, the wiring harness 130 of the electric pedal 100 can be installed along the direction of the connecting rod 110. After the wiring harness 130 is installed, the fixing member 200 is clamped on the connecting rod 110 by cooperating with the clamping portion 220 of the fixing member 200 and the clamping groove 111 on the connecting rod 110. At the same time, a tight wire threading channel 201 is formed between the clamping groove 111 and the connecting rod 110, which firmly encloses the wiring harness 130 and effectively prevents the wiring harness 130 from shaking and displacement. The installation of this wiring harness protection structure not only achieves the precise fixation of the position of the wiring harness 130, but also provides solid protection for the wiring harness 130.

[0039] More importantly, this structure effectively prevents the wiring harness 130 from hooking onto the connecting rod 110 of the electric pedal 100 due to its hanging position, thereby greatly reducing the risk of the wiring harness 130 breaking. It also prevents the wiring harness 130 from being easily exposed to contaminants, effectively improving the reliability and lifespan of the wiring harness 130.

[0040] In addition, the engagement between the engaging portion 220 and the engaging groove 111 makes assembly and disassembly of the fixing member 200 simple and quick. This greatly saves time and labor costs when maintaining or replacing the ambient light strip and wiring harness 130 in the future, thereby improving maintenance efficiency.

[0041] In some specific embodiments, a clamping plate 221 is symmetrically extended along the two edges of the opening of the docking groove 210 in the direction approaching the connecting rod 110, and a clamping protrusion 222 is provided on the opposite end surfaces of the two clamping plates 221; the two clamping plates 221 are clamped on the connecting rod 110, and the clamping protrusion 222 is inserted into the corresponding clamping groove 111, and the clamping plates 221 and the clamping protrusion 222 together form the clamping portion 220; by extending the clamping plate 221, we provide great convenience for the operator in actual operation. During the installation of the fixing member 200, the operator can clearly observe the matching of the clamping protrusion 222 and the clamping groove 111, thereby easily confirming whether they are correctly and reliably connected together.

[0042] In some specific embodiments, the clamping boss 222 is provided with a guide surface 2221 on the end surface close to the connecting rod 110, and the guide surface 2221 is located on the side of the clamping boss 222 away from the fixing member 200; the spacing between the two opposite guide surfaces 2221 gradually increases from the side close to the fixing member 200 to the side away from the fixing member 200, and the maximum spacing between the two opposite guide surfaces 2221 is not less than the width of the connecting rod 110, so that when the fixing member 200 is clamped to the connecting rod 110, the clamping bosses 222 of the two clamping plates 221 relative to each other will move away from each other under the action of the guide surface 2221 avoiding sliding relative to the connecting rod 110 when contacting the connecting rod 110, ensuring that the two clamping plates 221 are smoothly clamped on the connecting rod 110 and the clamping boss 222 is smoothly inserted into the clamping groove 111, reducing the installation difficulty of this embodiment.

[0043] In some specific embodiments, multiple clamping portions 220 are evenly distributed along the threading direction of the threading channel 201. The evenly distributed arrangement of multiple clamping portions 220 provides a redundant safety feature. Even if one clamping portion 220 fails for some reason, the other clamping portions 220 can still function, ensuring a secure connection between the fixing member 200 and the connecting rod 110. This redundant design not only improves the reliability of the connection but also greatly enhances the stability and durability of the entire structure.

[0044] Furthermore, evenly distributing multiple clamping portions 220 helps disperse stress, preventing damage caused by excessive stress at a single point. During the threading process, both the offset tension of the wiring harness 130 and the pressure of the external environment are shared by multiple clamping portions 220, effectively reducing the burden on a single clamping portion 220 and extending the overall service life.

[0045] like Figure 3 As shown, in some specific embodiments, the end surfaces of the two clamping plates 221 near the connecting rod 110 are respectively provided with pre-tightening washers 230. The purpose of the pre-tightening washers 230 is to provide additional pre-tightening force when the two clamping plates 221 are clamped on the connecting rod 110, thereby making the fit between the fixing member 200 and the connecting rod 110 more seamless. This tight fit not only effectively prevents loosening caused by vibration or external impact, but also improves the stability and durability of the entire connection structure.

[0046] It is worth noting that the material and thickness of the preload washer 230 have been carefully selected and calculated to ensure that they can provide sufficient preload without causing excessive wear or damage to the connecting rod 110 or the fixing member 200. This balanced design strategy ensures both a secure connection and long-term product reliability.

[0047] Furthermore, the provision of preload washer 230 makes the installation process smoother and more efficient. The operator can clearly feel the additional resistance provided by preload washer 230, allowing them to more accurately determine whether the clamping plate 221 is correctly and securely attached to the connecting rod 110. This intuitive feedback mechanism not only reduces installation difficulty but also improves installation quality.

[0048] In some specific embodiments, a curved portion 240 extends from the end of the fixing member 200 near the pedal 120, and the snap-in slot 111 extends correspondingly within the curved portion 240; the presence of the curved portion 240 enables the snap-in slot 111 to extend correspondingly therein. This design strategy allows for flexible bending arrangements of the snap-in slot 111 based on the actual layout requirements of the ambient light strip harness 130. Whether the layout of the harness 130 is linear, curved, or other complex shapes, the shape and angle of the curved portion 240 can be adjusted to achieve a perfect match between the snap-in slot 111 and the harness 130.

[0049] In some specific embodiments, the turning point between the fixing member 200 and the curved portion 240 defines an assembly hole 241, which communicates with the snap-in slot 111. The purpose of the assembly hole 241 is to effectively connect with the snap-in slot 111, thereby enabling the snap-in slot 111 to achieve corresponding connections even when the ambient light strip has multiple connection points for the wiring harness 130. This design strategy greatly enhances the flexibility and adaptability of the fixing member 200, enabling it to meet the installation requirements of various scenarios.

[0050] It's worth noting that the location and size of the mounting holes 241 have been carefully calculated and selected. They are positioned at the turning point between the fixing member 200 and the curved portion 240 to ensure smooth communication with the snap-in slot 111 without compromising the overall structural strength. Furthermore, the size of the mounting holes 241 is designed to accommodate the connection point of the ambient light strip's wiring harness 130, ensuring no obstructions during installation.

[0051] Furthermore, the interconnected design of assembly hole 241 and snap-in slot 111 provides additional convenience. When installing the ambient light strip, the operator can easily guide the connection point of the wiring harness 130 into the snap-in slot 111 through assembly hole 241 and secure it. This intuitive and simple installation method not only reduces operational difficulty but also improves installation efficiency.

[0052] In some specific embodiments, a cushion 250 is provided within the engaging groove 111 and on the side of the connecting rod 110 adjacent to the engaging groove 111. The cushion 250 is provided to provide effective shock absorption and protection for the wiring harness 130 within the wiring channel 201. In actual use, the wiring harness 130 may be damaged by various factors (such as vibration and friction), thereby affecting the normal operation of the entire system. The cushion 250 absorbs and disperses these external forces, thereby significantly reducing the probability of damage to the wiring harness 130.

[0053] Furthermore, the installation of the cushioning pad 250 provides additional convenience. When installing and removing the wiring harness 130, operators can operate more easily without worrying about damage to the wiring harness 130 due to friction or collision. This design not only improves installation efficiency but also reduces operational difficulty.

[0054] In some specific embodiments, the fixing member 200 is composed of multiple fixed segments 260. Each fixed segment 260 retains the necessary snap-fit ​​structures and connection interfaces, allowing for easy splicing and assembly. This allows operators to select a different number of fixed segments 260 to assemble, based on actual needs, to accommodate connecting rods 110 of varying lengths. This design not only avoids the limitations associated with the fixed length of the fixing member 200 but also improves resource utilization and cost-effectiveness.

[0055] It is worth mentioning that the connection between the fixed segments 260 utilizes a reliable connection mechanism and fasteners to ensure that the fixed segments 260 form a stable and strong overall structure after being spliced. At the same time, the design of the connection mechanism and fasteners fully considers the requirements of easy operation and maintenance, allowing operators to easily complete splicing and disassembly.

[0056] Furthermore, the design of the spliced ​​fixing segments 260 provides operators with more options and flexibility. The length and shape of the fixing member 200 can be flexibly adjusted to suit different application scenarios, depending on the specific installation environment and conditions. This design not only enhances the practicality and versatility of the fixing member 200, but also provides users with a more personalized and customized solution.
