Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to a wiring harness fixing structure, a lighting device, and a vehicle. Background Technology

[0002] With the development of technology and the improvement of living standards, people are placing increasingly higher demands on vehicle performance. Among these demands, circuit boards and other components within lighting devices are typically connected to the vehicle body external to the lighting fixture via wiring harnesses, with wiring harness fixing structures used to secure the harnesses.

[0003] In existing technologies, wire harness fixing structures typically use rubber plugs to connect to the light fixture. The wire harness is passed through the rubber plug, and a seal is achieved through an interference fit between the wire harness and the rubber plug. However, because the wire harness is rigid and extends along its axial direction, it requires a large assembly space. Furthermore, the rubber plug is prone to deformation or aging, resulting in poor sealing of the wire harness and creating an airtightness risk. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a wiring harness fixing structure, lighting device and vehicle that overcomes or at least partially solves the above problems.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a wire harness fixing structure, which includes: a housing and a sealing element;

[0007] The housing has a receiving cavity, the wire harness extends into the receiving cavity from a first direction, and at least a portion of the wire harness extending out of the receiving cavity forms an angle with the first direction;

[0008] The sealant fills the receiving cavity to seal the wire harness.

[0009] Optionally, the housing includes a sidewall with a limiting groove, and the wire harness is engaged with the limiting groove and extends out of the receiving cavity.

[0010] Optionally, at least a portion of the wire harness extending out of the receiving cavity is perpendicular to the first direction.

[0012] Optionally, the sealing member is rotatably connected to the housing to allow the sealing member to switch between a first position and a second position;

[0013] In the first position, the sealing member covers the receiving cavity; in the second position, the sealing member releases its obstruction of the receiving cavity, so that the receiving cavity is exposed along the first direction.

[0014] And / or, the plugging member is connected to the housing and plugs the seal to prevent the seal from leaking out;

[0015] And / or, the sealing member is provided with a limiting groove on the side near the receiving cavity, and the wire harness is snapped into the limiting groove;

[0016] And / or, the sealing element is detachably connected to the housing.

[0017] Optionally, the housing includes a base plate and a side wall protruding from and connected to the base plate. The housing is also provided with reinforcing ribs, which are respectively connected to the base plate and the side wall.

[0018] Optionally, the reinforcing rib includes a first reinforcing rib and a second reinforcing rib;

[0019] The first reinforcing rib is connected to the side wall and extends to the edge of the bottom plate;

[0020] The second reinforcing rib is connected to the side wall and has a gap between it and the edge of the bottom plate.

[0021] Optionally, the first reinforcing rib is disposed in the middle of the base plate, and the number of the second reinforcing ribs includes multiple ribs, which are symmetrically distributed on both sides of the first reinforcing rib;

[0022] And / or, the first reinforcing rib includes symmetrically distributed first and second arc-shaped reinforcing plates, the first and second arc-shaped reinforcing plates having the same radius of curvature; thus achieving a better transition effect.

[0023] And / or, the height of the first reinforcing rib is greater than the height of the second reinforcing rib;

[0024] And / or, the second reinforcing rib forms a triangular structure with the sidewall and the bottom plate.

[0025] Secondly, this application provides a lighting device, which includes a lamp housing and the aforementioned wiring harness fixing structure. The lamp housing has an installation port, and the wiring harness fixing structure is connected to the installation port.

[0026] Thirdly, embodiments of this application provide a vehicle that includes the aforementioned lighting device or the aforementioned wiring harness fixing structure.

[0027] In this embodiment, the wire harness fixing structure includes a housing and a seal. The housing has a receiving cavity, into which the wire harness extends from a first direction, with at least a portion of the wire harness extending out of the receiving cavity forming an angle with the first direction. The seal fills the receiving cavity to seal the wire harness. Thus, the housing provides a stable and reliable assembly structure for the wire harness, allowing the wire harness to pass through the receiving cavity of the housing and connect to an external structure. Furthermore, the fact that the wire harness extends from the first direction into the receiving cavity, with at least a portion extending out of the receiving cavity forming an angle with the first direction, changes the extension direction of the wire harness. This allows the wire harness to bend to extend at an angle to the first direction according to actual spatial layout requirements, saving assembly space, improving space utilization, and significantly reducing the assembly space required due to the rigid axial extension of the wire harness. In addition, filling the receiving cavity with the seal allows the seal to tightly cover the wire harness, achieving a better sealing effect and preventing the rubber stopper from easily deforming or aging, which could lead to poor sealing of the wire harness. This further reduces the risk of airtightness of the wire harness and improves sealing reliability.

[0043] Reference Figures 1 to 6 The diagram shows a schematic of a wire harness fixing structure according to an embodiment of the present application. The wire harness fixing structure may specifically include: a housing 10 and a sealing member 20; the housing 10 has a receiving cavity, the wire harness 15 extends into the receiving cavity from a first direction X, and at least a portion of the wire harness 15 extending out of the receiving cavity forms an angle with the first direction X; the sealing member 20 fills the receiving cavity to seal the wire harness 15.

[0044] In this embodiment, the housing 10 provides a stable and reliable assembly structure for the wire harness 15, such as an electrical wire, allowing the wire harness 15 to pass through the receiving cavity of the housing 10 and connect to the external structure. Furthermore, the wire harness 15 extends into the receiving cavity from a first direction X, with at least a portion of the wire harness 15 extending out of the receiving cavity forming an angle with the first direction X. Changing the extension direction of the wire harness 15 allows it to bend according to actual spatial layout requirements, extending at an angle with the first direction X. This helps save assembly space, improves space utilization, and significantly reduces the assembly space required by the wire harness 15 due to its rigid axial extension. In addition, the receiving cavity is filled with a sealing element 20, which tightly covers the wire harness 15, achieving a good sealing effect. This avoids the risk of deformation or aging of the rubber stopper causing poor sealing of the wire harness 15, further reducing the risk of airtightness and improving sealing reliability.

[0045] In this embodiment, the housing 10 has a cavity that provides bending space for the wire harness 15 and space for the sealing element 20. For example, the shape of the housing 10 can be circular, elliptical, or square, or it can be rectangular or other polygonal, and can be set according to actual needs. This embodiment does not limit the specific shape of the housing 10.

[0046] For example, in this embodiment, the wire harness 15 can extend into the receiving cavity within the housing 10 along its normal direction (i.e., its axial direction), and then extend out in a direction perpendicular to the normal direction of the housing 10, thus avoiding the need for a large assembly space after the wire harness 15 extends out. Alternatively, the wire harness 15 can extend into the receiving cavity within the housing 10 along its normal direction, and then extend out at an angle to the normal direction of the housing 10. Or, the wire harness 15 can also extend into the receiving cavity within the housing 10 along a direction inclined to the normal direction of the housing 10, and then extend out in another direction inclined to the normal direction of the housing 10, etc. This embodiment does not limit the specific implementation of these methods.

[0047] In this embodiment of the application, for example, the material of the shell 10 can be PA66 (Polyamide, nylon), which has good mechanical properties, as well as excellent wear resistance, rigidity, heat resistance and acid and alkali resistance. It also has good plasticity, is easy to process and manufacture, can be injection molded, is widely used and readily available.

[0048] For example, in this embodiment, the sealant 20 can be a sealant, such as a hot melt adhesive or a two-component adhesive, etc., which has good flowability and filling effect, making it easy to fill the cavity completely with the sealant 20. It has good adhesion, wrapping and sealing properties to the wire harness 15. The heat resistance, moisture resistance, etc. of the adhesive can be set according to the specific use environment, so that the sealant 20 has stable sealing performance. In addition, the sealant 20 can also be other structural adhesives, asphalt or resin materials, etc. The specific material of the sealant 20 is not limited in this embodiment.

[0049] Optionally, in this embodiment, the housing 10 includes a sidewall 11, and the sidewall 11 is provided with a limiting groove 12. The wire harness 15 is engaged with the limiting groove 12 and extends out of the receiving cavity. In this way, the limiting groove 12 limits the extension direction of the wire harness 15, achieving a better constraint effect on the extension direction of the wire harness 15, so that the wire harness 15 extends from a direction that forms an angle with the first direction X, improving reliability and preventing the wire harness 15 from extending in other directions due to its own rigidity, thus affecting the assembly space occupied by the wire harness 15.

[0050] For example, in this embodiment, the sidewall 11 may extend parallel to the first direction X, and the wire harness 15 extends from the limiting slot 12 perpendicular to the extension direction of the sidewall 11. Alternatively, the sidewall 11 may extend obliquely to the first direction X, so that the wire harness 15 extends obliquely from the limiting slot 12; this embodiment is not limited in this respect.

[0051] In some optional embodiments of this application, there are multiple limiting slots 12, which are spaced apart on the side wall 11. This allows multiple wire harnesses 15 to be constrained by the multiple limiting slots 12, with each wire harness 15 correspondingly engaged in one limiting slot 12, providing a good limiting effect. Alternatively, there may be only one limiting slot 12, with one or more wire harnesses 15 engaged in and extending out of one limiting slot 12. The specific number of limiting slots 12 is not limited in this application embodiment.

[0052] Optionally, in embodiments of this application, at least a portion of the wire harness 15 extending from the receiving cavity is perpendicular to the first direction X. For example, such as... Figure 2 As shown, at least a portion of the wire harness 15 can extend out of the receiving cavity along the second direction Y. In this way, the wire harness 15 extends into the receiving cavity of the housing 10 along the first direction X, and then extends out along the second direction Y, which is perpendicular to the first direction X, so that the insertion direction and the extension direction of the wire harness 15 are perpendicular to each other, occupying less assembly space and having a higher space utilization rate.

[0053] In this embodiment, optionally, the wire harness fixing structure further includes a sealing member 30, which is connected to the side of the housing 10 near the protruding part of the wire harness 15 to seal the receiving cavity. In this way, by sealing the opening of the receiving cavity with the sealing member 30, a better sealing effect is achieved, preventing the wire harness 15 from leaking out of the receiving cavity.

[0054] Optionally, in this embodiment, the sealing member 30 is rotatably connected to the housing 10 to switch between a first position and a second position; in the first position, the sealing member 30 covers the receiving cavity, and in the second position, the sealing member 30 releases the obstruction of the receiving cavity, so that the receiving cavity is exposed along the first direction X; and / or, the sealing member 30 is connected to the housing 10 and seals the sealing member 20 to prevent the sealing member 20 from overflowing; and / or, the sealing member 30 has a limiting groove on the side near the receiving cavity, and the wire harness 15 is snapped into the limiting groove; and / or, the sealing member 30 is detachably connected to the housing 10.

[0055] In this embodiment, the sealing member 30 can be rotated to the second position to release the obstruction of the receiving cavity. After the sealing member 20 is filled into the receiving cavity, the sealing member 30 can be rotated to the first position to seal the receiving cavity. Alternatively, the sealing member 30 is connected to the housing 10 to seal the sealing member 20 within the receiving cavity. That is, the sealing member 30 can seal the entire receiving cavity or only a portion of the receiving cavity filled with the sealing member 20, without sealing the entire cavity, thus preventing the sealing member 20 from overflowing from inside or outside the receiving cavity. Alternatively, a limiting groove is provided on the side of the sealing member 30 near the receiving cavity, allowing the wire harness 15 to engage with the limiting groove. The limiting groove on the sealing member 30 also achieves the limiting effect on the wire harness 15. That is, in this embodiment of the application, the wire harness 15 can be constrained and limited by the limiting slot 12 on the side wall 11 of the housing 10, and the wire harness 15 can be further constrained and limited by the limiting slot on the sealing member 30. In addition, the wire harness 15 can be constrained and limited more reliably by the limiting slot 12 on the side wall 11 of the housing 10 and the limiting slot on the sealing member 30.

[0056] And / or, the sealing element 30 can also be detachably connected to the housing 10. Thus, during assembly, the sealing element 30 is first separated from the housing 10, the wire harness 15 extends from the receiving cavity, the sealing element 20 is injected into the receiving cavity to seal the wire harness 15, and then the sealing element 30 is connected to the housing 10 to seal the sealing element 20, preventing the sealing element 20 from overflowing. That is, the sealing element 30 can be rotatably connected to the housing 10, or it can be detachably connected to the housing 10. The specific connection method between the sealing element 30 and the housing 10 is not limited in this embodiment.

[0057] For example, the sealing element 30 can be snapped onto the housing 10, or it can be connected to the housing 10 by fasteners such as screws or studs, etc. It can also be combined with welding and other methods to improve the connection reliability. In the embodiments of this application, the specific detachable connection method between the sealing element 30 and the housing 10 is not limited.

[0058] The various features of the aforementioned sealing element 30 can be arbitrarily combined according to actual needs to form multiple implementation methods. The specific structural type and connection method of the sealing element 30 are not limited in the embodiments of this application.

[0059] In this embodiment, the sealing member 30 is rotatably connected to the housing 10. During assembly, the sealing member 30 can be rotated to a first position to open it. After the wire harness 15 extends from the receiving cavity, it is convenient to inject the sealing member 20 into the receiving cavity to seal the wire harness 15. After sealing is completed, the sealing member 30 can be rotated to a second position to seal the sealing member 20 and prevent the sealing member 20 from overflowing.

[0060] For example, in the embodiments of this application, the sealing member 30 can be a sealing plate, and the size of the sealing member 30 can be equal to or close to the size of the opening of the receiving cavity, such as... Figure 3 and Figure 4 As shown, this causes the sealing element 30 to close the receiving cavity. Furthermore, the size of the sealing element 30 can also be larger than the size of the receiving cavity, such as... Figure 5 and Figure 6 As shown, the sealing member 30 extends downward to the outside of the housing 10 and has a relatively long length, which provides a better sealing effect on the cavity and can further constrain the wire harness 15 extending out of the housing 10.

[0061] In this embodiment of the application, for example, the sealing component 30 can be made of PA66 (Polyamide, nylon), which has good mechanical properties, as well as excellent wear resistance, rigidity, heat resistance and acid and alkali resistance. It also has good plasticity, is easy to process and manufacture, can be injection molded, is widely used and readily available.

[0062] For example, in this embodiment of the application, the specific assembly method of the wire harness fixing structure can be as follows: the wire harness 15 is inserted into the receiving cavity of the housing 10 along the first direction X, and then the wire harness 15 is bent at 90° and extends out from the limiting slot 12 of the side wall 11 of the housing 10, reducing the assembly space required by the wire harness 15. The sealing member 30 is rotatably connected to the housing 10 and is in the first open position. Then, sealant is applied to the receiving cavity of the housing 10. After the sealant fills the receiving cavity and seals the wire harness 15, the sealing member 30 is flipped and compacted to be in the second sealed position to prevent the sealant from overflowing, thus completing the assembly of the wire harness fixing structure.

[0063] Optionally, in this embodiment, the housing 10 includes a base plate 13 and a side wall 11 protruding and connected to the base plate 13. The housing 10 is also provided with reinforcing ribs, which are respectively connected to the base plate 13 and the side wall 11. In this way, the base plate 13 and the side wall 11 are structurally strengthened by the reinforcing ribs, so that the housing 10 has better structural strength and improves structural stability.

[0064] Optionally, in this embodiment, the reinforcing rib includes a first reinforcing rib 14 and a second reinforcing rib 15; the first reinforcing rib 14 is connected to the sidewall 11 and extends to the edge of the bottom plate 13; the second reinforcing rib 15 is connected to the sidewall 11 and has a gap with the edge of the bottom plate 13. Thus, the first reinforcing rib 14 provides better structural reinforcement to the area between the edges of the sidewall 11 and the bottom plate 13, and the second reinforcing rib 15 provides better structural reinforcement to the area between the sidewall 11 and the bottom plate 13 that does not reach the edge, further enhancing the structural reinforcement effect of the reinforcing rib on the shell 10.

[0065] Optionally, in this embodiment, the first reinforcing rib 14 is disposed in the middle of the base plate 13, and the number of second reinforcing ribs 15 includes multiple second reinforcing ribs 15 symmetrically distributed on both sides of the first reinforcing rib 14. This symmetrical distribution of multiple second reinforcing ribs 15 on both sides of the first reinforcing rib 14 results in a more uniform and symmetrical distribution of the first and second reinforcing ribs 14, providing a more uniform and stable stress effect and further improving structural stability. And / or, the first reinforcing rib 14 includes symmetrically distributed first arc-shaped stiffeners 141 and second arc-shaped stiffeners 142, with the same radius of curvature. This provides a better connection and transition effect between the first and second arc-shaped stiffeners 141 and 142, improving the structural strength of the first reinforcing rib 14. And / or, the height of the first reinforcing rib 14 is greater than the height of the second reinforcing rib 15. This allows the reinforcing ribs to have different stress strengths at different heights, further improving the structural reinforcement effect of the reinforcing ribs at different heights. And / or, the second reinforcing rib 15 forms a triangular structure with the side wall 11 and the bottom plate 13. Since the triangle has good structural stability, the second reinforcing rib 15 forms a triangular structure with the side wall 11 and the bottom plate 13, so that the second reinforcing rib 15 has a more stable structural reinforcement effect on the shell 10, thereby improving reliability.

[0066] For example, in this embodiment, the radius of curvature of the first arc-shaped rib 141 can be any value between 10mm and 30mm, such as 10mm, 15mm, 20mm, or 30mm, etc., and can be set according to actual needs. This embodiment does not limit the specific value of the radius of curvature of the first arc-shaped rib 141. Similarly, the radius of curvature of the second arc-shaped rib 142 can be any value between 10mm and 30mm, such as 10mm, 15mm, 20mm, or 30mm, etc., and can be set according to actual needs. This embodiment also does not limit the specific value of the radius of curvature of the second arc-shaped rib 142.

[0067] In this embodiment, the height of the first reinforcing rib 14 can be any value between 5 and 10 mm, such as 5 mm, 8 mm, or 10 mm, etc., and can be set according to actual needs. This embodiment does not limit the specific value of the height of the first reinforcing rib 14. Similarly, the height of the second reinforcing rib 15 can be any value between 5 and 10 mm, such as 5 mm, 8 mm, or 10 mm, etc., and can be set according to actual needs. This embodiment does not limit the specific value of the height of the second reinforcing rib 15.

[0068] The features of the first reinforcing rib 14 and the second reinforcing rib 15 described above can be arbitrarily combined according to actual needs to form various implementation methods. The specific structural type, distribution method and size setting of the first reinforcing rib 14 and the second reinforcing rib 15 are not limited in the embodiments of this application.

[0069] In summary, the wire harness fixing structure of the embodiments of this application can include at least the following advantages:

[0070] In this embodiment, the wire harness fixing structure includes a housing and a seal. The housing has a receiving cavity, into which the wire harness extends from a first direction, with at least a portion of the wire harness extending out of the receiving cavity forming an angle with the first direction. The seal fills the receiving cavity to seal the wire harness. Thus, the housing provides a stable and reliable assembly structure for the wire harness, allowing the wire harness to pass through the receiving cavity of the housing and connect to an external structure. Furthermore, the fact that the wire harness extends from the first direction into the receiving cavity, with at least a portion extending out of the receiving cavity forming an angle with the first direction, changes the extension direction of the wire harness. This allows the wire harness to bend to extend at an angle to the first direction according to actual spatial layout requirements, saving assembly space, improving space utilization, and significantly reducing the assembly space required due to the rigid axial extension of the wire harness. In addition, filling the receiving cavity with the seal allows the seal to tightly enclose the wire harness, achieving a better sealing effect and preventing the rubber stopper from easily deforming or aging, which could lead to poor sealing of the wire harness. This further reduces the risk of airtightness of the wire harness and improves sealing reliability.

[0071] This application also provides a lighting device, referring to... Figures 7 to 8 This illustration shows a schematic diagram of a wiring harness fixing structure applied to a lighting device according to an embodiment of this application. The lighting device includes a lamp housing 40 and a wiring harness fixing structure. The lamp housing 40 is provided with a mounting port 41, and the wiring harness fixing structure is connected to the mounting port 41. By providing a wiring harness fixing structure on the lighting device, the wiring harness 15 inside the lighting device is fixed, so that when it extends to connect to the vehicle wiring harness 15 outside the lighting device, it occupies less assembly space and improves space utilization.

[0072] In this embodiment, for example, a threaded ring can be provided on the outer periphery of the housing 10, and a corresponding threaded structure can be provided on the mounting opening 41 of the lamp housing 40. By rotating the housing 10, the threaded ring of the housing 10 is threadedly connected to the threaded structure of the mounting opening 41, achieving a relatively simple and reliable installation of the housing 10 and the lamp housing 40. Furthermore, a baffle can be provided on the side of the housing 10 near the outside of the lamp device to facilitate rotational installation of the housing 10 by the operator. In some alternative embodiments of this application, multiple reinforcing ribs can be provided on the housing 10 to structurally strengthen the location of the receiving cavity, thereby improving structural strength.

[0073] Optionally, in this embodiment, the lighting device further includes a sealing ring 50, which is connected between the wiring harness fixing structure and the mounting port 41. Specifically, the sealing ring 50 is disposed between the housing 10 of the wiring harness fixing structure and the mounting port 41, so that the sealing ring 50 is compressed axially, thereby providing a relatively stable sealing performance between the wiring harness fixing structure and the lamp housing 40.

[0074] For example, in the embodiments of this application, the sealing ring 50 can be made of EPDM (Ethylene Propylene Diene Monomer), which has good heat resistance and acid and alkali resistance, good aging resistance, and is a commonly used sealing material with wide application and easy availability.

[0075] In summary, the lighting device according to the embodiments of this application may include at least the following advantages:

[0076] In this embodiment, the lighting device includes a lamp housing and a wiring harness fixing structure. The lamp housing has a mounting opening, and the wiring harness fixing structure is connected to the mounting opening. The wiring harness fixing structure includes a housing and a sealing element. The housing has a receiving cavity, and the wiring harness extends into the receiving cavity from a first direction, with at least a portion of the wiring harness extending out of the receiving cavity forming an angle with the first direction. The sealing element fills the receiving cavity to seal the wiring harness. Thus, the housing provides a relatively stable and reliable assembly structure for the wiring harness, allowing the wiring harness to pass through the receiving cavity of the housing and connect to the external structure. Furthermore, the fact that the wiring harness extends into the receiving cavity from the first direction, with at least a portion extending out of the receiving cavity forming an angle with the first direction, changes the extension direction of the wiring harness. This allows the wiring harness to bend to extend at an angle with the first direction according to actual spatial layout requirements, which helps save assembly space, improves space utilization, and significantly reduces the assembly space required by the wiring harness due to its rigid axial extension. In addition, the sealing element is filled into the cavity, so that the sealing element tightly covers the wire harness, achieving a better sealing effect on the wire harness. This avoids the poor sealing performance of the wire harness caused by the deformation or aging of the rubber plug, further reducing the airtightness risk of the wire harness and improving the sealing reliability.

[0077] For example, in the embodiments of this application, the vehicle may include a small car, a medium-sized car, a sedan, a truck, a trailer, a CDV (Car Derived Van), an MPV (Multi-Purpose Vehicle), an SUV (Sport Utility Vehicle), etc. The specific type of vehicle is not limited in the embodiments of this application.

[0078] The vehicle in this application embodiment may include at least the following advantages:

[0079] In this embodiment, the vehicle includes a lighting device or a wiring harness fixing structure. The lighting device includes a lamp housing and a wiring harness fixing structure. The lamp housing has a mounting opening, and the wiring harness fixing structure is connected to the mounting opening. The wiring harness fixing structure includes a housing and a seal. The housing has a receiving cavity, and the wiring harness extends into the receiving cavity from a first direction, with at least a portion of the wiring harness extending out of the receiving cavity forming an angle with the first direction. The seal fills the receiving cavity to seal the wiring harness. Thus, the housing provides a relatively stable and reliable assembly structure for the wiring harness, allowing the wiring harness to pass through the receiving cavity of the housing and connect to the external structure. Furthermore, the fact that the wiring harness extends into the receiving cavity from the first direction, with at least a portion of the wiring harness extending out of the receiving cavity forming an angle with the first direction, changes the extension direction of the wiring harness. This allows the wiring harness to bend to extend at an angle with the first direction according to actual spatial layout requirements, which helps save assembly space, improves space utilization, and significantly reduces the assembly space required by the wiring harness due to its rigid axial extension. In addition, the sealing element is filled into the cavity, so that the sealing element tightly covers the wire harness, achieving a better sealing effect on the wire harness. This avoids the poor sealing performance of the wire harness caused by the deformation or aging of the rubber plug, further reducing the airtightness risk of the wire harness and improving the sealing reliability.
