Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a protective tail cover for automotive wiring harnesses. Background Technology

[0002] With the continuous development of technology, the construction of buildings between cities has increased. In order to form better transportation infrastructure between cities and thus increase urban communication and development, a large number of transportation tools are used, such as railways, waterways and automobiles. Nowadays, adjacent cities usually use automobiles for transportation to make transportation between cities more convenient. However, automobiles are consumables, and the various connecting parts on automobiles are prone to wear and damage.

[0003] During vehicle use, especially in the chassis area, wiring harnesses can wear down and break, affecting vehicle operation and creating unnecessary safety hazards. Existing protective covers for wiring harnesses have poor overall waterproof and dustproof performance. The plastic material results in poor protective performance, inadequate protection and heat dissipation for the wiring harness, and the protective cover is too cumbersome to disassemble, making it difficult to quickly inspect and repair internal wiring harness problems. Summary of the Invention

[0004] This disclosure relates to a protective tail cover for automotive wiring harnesses. First, a heat dissipation component is snap-fitted onto the outer wall of the main wiring harness. The inner toothed rack of the heat dissipation component contacts the main wiring harness to form an anti-slip effect. The reinforcing ribs added between the snap-fit ​​component and the protective component increase the connection strength between the protective component and the snap-fit ​​component. A contact component is snap-fitted onto the inner end of the snap-fit ​​component. The ends of two symmetrical sets of snap-fit ​​components are hinged together, allowing the snap-fit ​​component to drive the contact component to clamp onto the outer end of the main wiring harness. After the protective component and the snap-fit ​​component are closed, the protective component is quickly fixed by the fixing component at its outer end. At this time, the protective component is pulled to place it on the outer end of the heat dissipation component, allowing the connecting component at the outer end of the heat dissipation component to snap onto the inner wall of the protective component. Finally, the outer end of the protective component is connected to the corresponding slot device to complete the installation.

[0010] In at least some embodiments, the outer protrusion of the fixing component is disposed at the upper and lower ends of the protective component, a cut is provided on the outer side wall of the outer protrusion, and a snap-fit ​​block is slidably engaged on the outer protrusion.

[0011] In at least some embodiments, the fastening cylinder of the heat dissipation assembly is configured as a semi-cylindrical structure, the contact surface of the fastening cylinder is provided with a locking block, the inner wall of the fastening cylinder is provided with an internal toothed rack, the internal toothed rack is configured as a spiral structure, and the outer wall of the fastening cylinder is provided with heat dissipation fins.

[0012] In at least some embodiments, the connecting piece of the connecting component is disposed on the outer wall of the heat dissipation component, the end of the connecting piece is provided with a connecting rod, the connecting piece is provided with a buffer ring, the buffer ring is composed of two sets of rings, and the middle of the buffer ring of the connecting piece is provided with a disconnect structure.

[0013] This invention provides a protective tail cover for automotive wiring harnesses, which has the following beneficial effects: In this invention, two symmetrical sets of heat dissipation components are snapped onto the outer wall of the main wiring harness, allowing the inner toothed rack of the heat dissipation component to make tight contact with the main wiring harness, thus achieving stable fixation between the heat dissipation component and the main wiring harness. The heat sink at the outer end of the heat dissipation component dissipates heat from the main wiring harness. At this time, the contact component is snapped onto the inner wall of the fastening component, so that the spacing groove of the contact component corresponds to the spacing of the fastening component. The fastening component is directly connected to the protective component. The reinforcing rib between the protective component and the fastening component has the function of stably fixing the fastening component to the protective component. After connecting the ends of the symmetrical fastening components, the fastening component and the protective component are directly fastened together. At this time, the contact component of the fastening component will make tight contact with the main wiring harness, allowing the contact component of the fastening component to form a certain bend on the main wiring harness. For enhanced protection, the outer end of the closed protective component is quickly snapped into place by the fixing component, enabling rapid fixation of the protective component and other components such as the fastening component. This allows for quick assembly and disassembly. Simultaneously, the outer end of the heat dissipation component connects to the connecting component. Sliding the entire protective component allows its inner end to snap into and fix with the connecting component, placing the connecting component between the heat dissipation component and the protective component. This creates a buffer for the wiring harness, providing protection for the main wiring harness. The outer wall of the protective component features guide holes with a larger inner diameter and a smaller outer diameter to prevent the entry of external dust and moisture while allowing for airflow and heat dissipation. Finally, the connecting block on the protective component is attached to the corresponding position on the vehicle, completing the installation of the tailgate and protecting the main wiring harness.

[0014] Furthermore, the contact rings are arranged in an array, with cavities inside to provide elasticity and better fit against the main wire harness. The contact pieces of the contact rings also ensure better contact with the main wire harness. The external holes at the connection points of the contact rings facilitate quick and easy installation of the contact assembly onto the fastening assembly. Because the contact rings are semi-circular, contact blocks are placed on the side contact points of the contact rings to ensure better sealing during symmetrical contact. This allows the symmetrical contact rings to form better contact after being symmetrically fastened onto the main wire harness, achieving a stable contact and sealing effect on the main wire harness.

[0015] Furthermore, the fastening bracket is designed with a rectangular toothed structure, allowing the hinge blocks at the ends of the two sets of fastening brackets to connect quickly. This enables the fastening brackets to snap onto the main wire harness after connection, forming an annular cylindrical shape. The contact teeth of the fastening bracket are designed with staggered sawtooth shapes, allowing the fastening brackets to snap onto each other through the corresponding contact teeth, thus preventing misalignment of the fastening components. A fixing block is provided on the inner wall of the fastening bracket, aligning the fixing block with the outer hole of the contact component. This allows the contact component to be snapped onto the fastening component through the fixing block. A protrusion is provided on the fixing block, achieving a stable effect after the contact component is installed onto the fastening component.

[0016] In addition, reinforcing plates are first installed at the corners of the inner wall of the protective shell, so that the triangular reinforcing plates can provide overall support and reinforcement for the protective component. The connecting blocks of the protective shell connect to the main wiring harness. The protective strips set on the outer end of the protective shell provide stable protection when the protective component is installed by hand, making it easier to bend and use the protective component. In order to prevent the main wiring harness inside the protective component from dissipating heat, guide holes are set at the top and bottom of the protective strips of the protective shell. The guide holes are designed with a structure that is larger inside and smaller outside, making it difficult for external dust and moisture to enter. They also guide airflow, allowing heat inside the protective shell to be quickly discharged. This allows the protective component to dissipate heat while also providing a certain degree of waterproof and dustproof protection. The connecting points at the top and bottom of the protective component are provided with external protrusions. The outer ends of the external protrusions are cut, and the protrusions with notches can slide and engage with the locking blocks. After the protective component is closed, it is fixed by the locking blocks.

[0017] Furthermore, by directly installing locking blocks on the contact surface of the fastening cylinders, two sets of fastening cylinders can be directly snapped onto the outer wall of the main wiring harness. The internal toothed rack on the inner wall of the fastening cylinder has a stable and increasing effect on the fixation between the heat dissipation component and the main wiring harness, allowing the heat dissipation component to be stably fixed at the outer end of the main wiring harness. Because the fastening cylinders are designed to directly contact the main wiring harness, heat dissipation fins are directly installed at the outer end of the fastening cylinders to increase the external area of ​​the fastening cylinders and achieve better heat dissipation.

[0018] Furthermore, by directly mounting the connecting piece on the outer wall of the heat dissipation component, the connecting piece also assists in heat dissipation of the heat dissipation component. The connecting rod at the end of the connecting piece connects to the protective component, thus connecting the heat dissipation component in the middle of the protective component, thereby ensuring the stability of the main wire harness within the protective component. The connecting piece is equipped with a buffer ring, which, through two sets of rings forming a buffer, allows the connecting component to buffer the main wire harness connected to the protective component, achieving better protection for the main wire harness.

The contact ring 201 is arranged in an array, and a cavity is provided at the inner end of the contact ring 201. The contact surface between the contact ring 201 and the main wire harness 1 is a contact piece 203. The contact ring 201 has an outer hole 204. By arranging the contact ring 201 in an array and providing a cavity inside the contact ring 201, the contact ring 201 has a certain degree of elasticity, allowing it to better fit tightly against the main wire harness 1. The contact piece 203 of the contact ring 201 also has better contact with the main wire harness 1. The external hole 204 provided at the connection of the contact ring 201 facilitates the quick and easy installation of the contact assembly 2 onto the fastening assembly 3. The side contact surface of the contact ring 201 is provided with a contact block 202. Because the contact ring 201 is designed as a semi-circular structure, in order to better seal the contact ring 201 when it is in symmetrical contact, the contact block 202 is directly provided at the side contact surface of the contact ring 201. This allows the symmetrical contact rings 201 to form a better contact after they are symmetrically fastened onto the main wire harness 1, thereby achieving a stable contact and sealing effect on the main wire harness 1.

[0025] In this embodiment of the disclosure, such as Figure 3 Figure 4As shown, the fastening frame 301 of the fastening assembly 3 is configured as a semi-circular frame structure. A hinge block is provided at the end of the fastening frame 301, and contact teeth 303 are provided on the contact surface of the fastening frame 301. The contact teeth 303 are configured as an interlaced sawtooth structure. Firstly, the fastening frame 301 is configured as a rectangular tooth structure, allowing the hinge blocks at the ends of the two sets of fastening frames 301 to connect quickly. This achieves the effect of the fastening frame 301 being snapped onto the main wire harness 1 to form an annular cylindrical shape after connection. The interlaced sawtooth structure of the contact teeth 303 of the fastening frame 301 further facilitates the connection of the fastening frame... 301 is engaged with the contact teeth 303 to prevent misalignment of the fastening assembly 3. The inner wall of the fastening bracket 301 is provided with a fixing inner block 302 with a protrusion. The fixing inner block 302 is positioned on the inner wall of the fastening bracket 301 so that it corresponds with the outer hole 204 of the contact assembly 2. This allows the contact assembly 2 to be fastened to the fastening assembly 3 by the fixing inner block 302. The protrusion on the fixing inner block 302 ensures the stability of the contact assembly 2 after it is installed on the fastening assembly 3.

[0026] In this embodiment of the disclosure, such as Figure 4 As shown, the reinforcing rib 4 is installed on the outer wall between the protective component 5 and the fastening component 3. The reinforcing rib 4 is set as a triangular plate structure. Two sets of reinforcing ribs 4 are set on each protective component 5 and fastening component 3. In order to make the connection between the fastening component 3 and the protective component 5 more stable, and to ensure that the fastening component 3 does not reduce its strength while dissipating heat from the main wire harness 1, the reinforcing rib 4 is directly installed between the protective component 5 and the fastening component 3. The triangular reinforcing rib 4 makes the connection between the protective component 5 and the fastening component 3 more stable and increases the strength of the fastening component 3.

[0027] In this embodiment of the disclosure, such as Figure 3As shown, the protective shell 501 of the protective assembly 5 is connected to the fastening assembly 3. A connecting block 502 is provided on the protective shell 501, and a protruding strip is provided at the connecting block 502. A protective strip 503 is provided on the outer wall of the protective shell 501. A reinforcing plate 505 is provided at the corner of the inner wall of the protective shell 501. The reinforcing plate 505 is a triangular structure. Firstly, the reinforcing plate 505 is provided at the corner of the inner wall of the protective shell 501, so that the triangular reinforcing plate 505 provides overall support and reinforcement for the protective assembly 5. The connecting block 502 of the protective shell 501 connects to the main wire harness 1. The protective strip 503 provided on the outer end of the protective shell 501 has the function of... When the protective component 5 is installed, it provides stable protection and makes it easier to bend and use. The protective strip 503 of the protective shell 501 is provided with guide holes 504 at both the upper and lower ends. The inner end of each set of guide holes 504 is larger than the outer end. In order to prevent the main wire harness 1 inside the protective component 5 from having a heat dissipation function, guide holes 504 are directly provided at the upper and lower ends of the protective strip 503 of the protective shell 501. The guide holes 504 are designed with a structure that is larger inside and smaller outside, making it difficult for external dust and moisture to enter. They also guide the airflow to a certain extent, allowing the heat inside the protective shell 501 to be quickly discharged. This allows the protective component 5 to have a certain waterproof and dustproof function while dissipating heat.

The internal gear 702 is configured as a spiral structure. The locking block is directly set on the contact surface of the fastening cylinder 701, so that the two sets of fastening cylinders 701 can be directly snapped onto the outer wall of the main wire harness 1. The internal gear 702 on the inner wall of the fastening cylinder 701 has a stable and increasing effect on the fixation between the heat dissipation assembly 7 and the main wire harness 1, so that the heat dissipation assembly 7 is stably fixed at the outer end of the main wire harness 1. The outer wall of the fastening cylinder 701 is provided with a heat sink 703. Because the fastening cylinder 701 is designed to directly contact the main wire harness 1, in order to ensure stable heat dissipation of the main wire harness 1, the heat sink 703 is directly set on the outer end of the fastening cylinder 701, increasing the external area of ​​the fastening cylinder 701 and achieving a better heat dissipation effect.

[0030] In this embodiment of the disclosure, such as Figure 6 As shown, the connecting piece 801 of the connecting component 8 is disposed on the outer wall of the heat dissipation component 7. A connecting rod is provided at the end of the connecting piece 801. A buffer ring 802 is provided on the connecting piece 801. The buffer ring 802 is composed of two sets of rings.

The connecting rod at the end of the connecting piece 801 is connected to the protective component 5, so as to connect the heat dissipation component 7 in the middle of the protective component 5, thereby ensuring the stability of the main wire harness 1 in the protective component 5. The buffer ring 802 provided on the connecting piece 801, through the buffer ring 802 composed of two sets of rings, has the function of buffering the main wire harness 1 connected to the protective component 5 by the connecting component 8, so as to achieve better protection of the main wire harness 1.

[0031] The working principle of this embodiment is as follows: During installation, first select the connection position between the device and the main wiring harness 1, open the symmetrical heat dissipation components 7 at both ends, and align the fastening cylinders 701 with the slots at the contact positions on the outer wall to engage the two sets of semi-circular fastening cylinders 701. This allows the inner rack 702 of the fastening cylinders 701 to stably contact the outer wall of the main wiring harness 1, forming a stable fixing effect of the heat dissipation components 7 after installation. At this time, observe the gap grooves on the fastening bracket 301 and the contact ring 201, and engage the contact ring 201 with the fixing inner block 302 of the fastening bracket 301, aligning the fastening bracket 301 with the gap grooves of the contact ring 201. The fastening component 3 is set to be directly connected to the protective component 5, and a reinforcing rib 4 is added between the fastening component 3 and the protective component 5. At this time, align the ends of the two symmetrical sets of fastening brackets 301 with the main wiring harness 1. To connect, the protective component 5 and the fastening component 3 are directly fastened together, allowing the contact component 2 of the fastening component 3 to form a stable and tight fit on the main wire harness 1. At this time, the outer protrusions 601 at the upper and lower ends of the protective component 5 will be aligned. The snap-fit ​​block 602 is snapped onto the outer protrusion 601 to achieve the connection and fixation of the protective component 5. The outer end of the heat dissipation component 7 is provided with a connecting component 8. After the protective component 5 and other components are installed, the protective component 5 is pulled directly toward the heat dissipation component 7, allowing the outer end of the connecting component 8 to snap directly into the inner wall of the protective component 5, achieving a stable connection between the heat dissipation component 7 and the protective component 5 through the connecting component 8. Finally, the connecting block 502 of the protective component 5 is snapped onto the required installation position to complete the installation of the end of the main wire harness 1. When disassembling the whole assembly, simply pull out the connecting block 502 of the protective component 5. Then, pull the protective component 5 outward to separate the connecting component 8 from the inside of the protective component 5, which makes it easier to disassemble the heat dissipation component 7. Next, slide the outer fixing component 6 of the protective component 5 off and separate the protective component 5 directly towards both ends, so that the contact component 2 of the fastening component 3 is separated from the main wiring harness 1, thereby completing the separation of the main wiring harness 1 and realizing the quick assembly and disassembly of the device on the main wiring harness 1.
