Description

Technical Field

[0001] This invention belongs to the field of vehicle structural design technology, and specifically relates to a wiring harness docking assembly for a vehicle and a vehicle. Background Technology

[0002] Wire harness connectors are electrical connection components widely used in various electronic and electrical equipment and instruments, such as electronic devices, automobiles, aerospace, and communication equipment. Wire harness connectors typically consist of an insulator and contact parts, serving as a positioning connector for connecting electronic circuits. Wire harness connectors are mostly installed in pairs; one connector has a terminal protruding from its end, while the other has a conductive cavity to accommodate the terminal. Inserting the terminal into the conductive cavity enables signal transmission and circuit conversion. Mid-sized vehicles with seven or more seats, such as commercial vehicles, are often equipped with magic folding seats. These seats have two operating states: when unfolded, they can be used as the last row of rear seats; when folded forward, they expand the trunk space. As vehicles become increasingly intelligent and automated, a circuit connection is needed between the magic folding seats and the vehicle body to determine the current state of the seats or control their automatic folding operation.

[0003] Existing folding seats and vehicle bodies are connected to wiring harnesses for signal transmission. Each harness has a connector at its end; when two connectors are connected, data transmission between the seat and the vehicle body is possible. After the connectors are plugged in, simple clips are typically used to secure the assembly between the two connectors to the gap between the seat and the vehicle body. However, in existing technology, the clips used to secure the assembly are quite tall. The resulting wiring harness assembly, after being secured to the assembly, is taller than the gap itself, leading to an increase in the local height of the vehicle's inner floor surface. This is unfavorable for storing large items such as luggage. Summary of the Invention

[0004] The purpose of this invention is to provide a wiring harness docking assembly and a vehicle for use in vehicles, thereby reducing the overall height of the wiring harness docking assembly and avoiding local bulges on the inner bottom surface of the vehicle body.

[0005] To achieve the above objectives, the present invention provides a wiring harness connection assembly for a vehicle, the wiring harness connection assembly comprising:

[0006] A first wiring harness connector is provided on a first wiring harness extending from the interior of the vehicle's seat.

[0007] The second wiring harness connector is used to be disposed on the second wiring harness extending from the interior of the vehicle body and can be plugged into the first wiring harness connector.

[0008] The fastener is located in the gap between the seat and the vehicle body and has a receiving groove for accommodating the combination of the first wiring harness connector and the second wiring harness connector after they are plugged in.

[0009] In some embodiments, the receiving slot is a slot in which the combination of the first wire harness connector and the second wire harness connector is engaged.

[0010] In some implementations, the fastener is made of foam, silicone, or rubber.

[0011] In some embodiments, the outer contour of the assembly of the first wire harness connector and the second wire harness connector is adapted to the shape and size of the inner contour of the receiving groove.

[0012] In some embodiments, the fastener also has a clearance space for avoiding the first or second wiring harness.

[0013] A second aspect of the present invention provides a vehicle, including a body; a seat mounted on the body; and the aforementioned wiring harness docking assembly for the vehicle.

[0014] In some embodiments, the vehicle also includes a foot cover mounting bracket and a connector. The foot cover mounting bracket has a groove formed therein. The connecting head of the connector is engaged with the bottom wall of the groove. The connecting rod of the connector passes through the bottom wall of the groove and is connected to the vehicle body. The fastener is disposed in the groove and engaged with the connecting head.

[0015] In some embodiments, a receiving hole is formed on the bottom wall of the fastener to receive the connecting head and form an interference fit with the connecting head.

[0016] In some implementations, there are multiple receiving holes and multiple connectors, and the positions of the multiple receiving holes correspond one-to-one with the positions of the multiple connectors.

[0017] In some implementations, the depth of the receiving hole is greater than or equal to the height of the connecting head.

[0018] The above-mentioned technical solution provides a wiring harness docking assembly for a vehicle. The assembly includes: a first wiring harness connector for mounting on a first wiring harness extending from the interior of the vehicle seat; a second wiring harness connector for mounting on a second wiring harness extending from the interior of the vehicle body and capable of being plugged into the first wiring harness connector; and a fixing member disposed in the gap between the seat and the vehicle body, forming a receiving groove for accommodating the assembly of the first and second wiring harness connectors after plugging. The fixing member is disposed in the gap between the seat and the vehicle body, and the receiving groove is formed therein, where the assembly of the first and second wiring harness connectors is accommodated. In the prior art, the assembly of the first and second wiring harness connectors is fixed by a snap-fit ​​mechanism. The wiring harness docking assembly formed by the snap-fit ​​mechanism, the first wiring harness connector, and the second wiring harness connector is relatively high, which can easily cause localized bulges on the inner bottom surface of the vehicle body. The fastener provided by the present invention includes a receiving groove, which can accommodate the combination of the first wire harness connector and the second wire harness connector. Using the above-mentioned wire harness docking assembly, the overall height of the wire harness docking assembly is the height of the fastener. The first wire harness connector and the second wire harness connector are both located in the receiving groove of the fastener, which effectively reduces the height of the wire harness docking assembly and prevents local bulging of the inner bottom surface of the vehicle body.

[0042] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0043] The wiring harness docking assembly and vehicle according to the present invention are described below with reference to the accompanying drawings. Figure 1 The diagram shown is a schematic representation of the usage environment of a wiring harness docking assembly for a vehicle provided according to an embodiment of the present invention; as follows: Figure 2 The diagram shown is a structural schematic of a wiring harness docking assembly for a vehicle provided according to an embodiment of the present invention; as shown Figure 3 The diagram shown is a structural schematic of the fastener 30 provided according to an embodiment of the present invention. The wire harness docking assembly includes:

[0044] The first wiring harness connector 10 is used to be disposed on a first wiring harness (not shown) extending from the interior of the seat 1 of the vehicle.

[0045] The second wiring harness connector 20 is used to be installed on the second wiring harness (not shown in the figure) extending from the interior of the vehicle body 2 and can be plugged into the first wiring harness connector 10.

[0046] The fastener 30 is disposed in the gap 3 between the seat 1 and the body 2 and has a receiving groove 31. The receiving groove 31 is used to receive the combination of the first wire harness connector 10 and the second wire harness connector 20 after they are plugged in.

[0047] Wiring harness connectors are mostly installed in pairs. One connector has a terminal protruding from its end, and the other has a conductive cavity to accommodate the terminal. Inserting the terminal into the conductive cavity enables signal transmission and circuit conversion. The wiring harness docking assembly is used to connect the wiring harness of the vehicle body 2 to the wiring harness of the seat 1, enabling signal communication between the vehicle body 2 and the seat 1. In the prior art, the assembly formed by the wiring harness connectors of the vehicle body 2 and the seat 1 is mostly fixed by simple fixing structures such as clips. These clips and other fixing structures often have a relatively high base, resulting in a high overall height after fixing, exceeding the depth of the gap 3 between the vehicle body 2 and the seat 1, causing a localized bulge on the inner bottom surface of the vehicle body 2.

[0048] In this embodiment of the invention, the wiring harness docking assembly includes a first wiring harness connector 10, a second wiring harness connector 20, and a fixing member 30. The first wiring harness connector 10 is used to connect a first wiring harness extending from the inside of the seat 1, and the second wiring harness connector 20 is used to connect a second wiring harness extending from the inside of the vehicle body 2. The connection of the first wiring harness connector 10 and the second wiring harness connector 20 together enables signal communication between the seat 1 and the vehicle body 2. In existing vehicles, there is a gap 3 between the seat 1 and the vehicle body 2. This gap 3 has a certain depth and can be used to accommodate small components, such as the assembly formed by the first wiring harness connector 10 and the second wiring harness connector 20. However, the assembly needs a fixing structure for fixation. If a fixing structure such as a buckle is used, the height would be too high, causing a local bulge on the inner bottom surface of the vehicle body 2. In this embodiment of the invention, the fastener 30 is disposed in the gap 3. The fastener 30 has a receiving groove 31, which can be used to accommodate the assembly formed by the first wire harness connector 10 and the second wire harness connector 20. The assembly is fixed in the above manner. The height of the wire harness docking assembly is the height of the fastener 30, which effectively reduces the overall height of the wire harness docking assembly and avoids the occurrence of local bulges on the inner bottom surface of the vehicle body 2, so as to facilitate the storage of large items such as suitcases.

[0049] In one embodiment, the receiving groove 31 is a slot, and the assembly of the first wire harness connector 10 and the second wire harness connector 20 is engaged in the slot. The receiving groove 31, by limiting and engaging the assembly of the first wire harness connector 10 and the second wire harness connector 20, enables a more stable installation of the assembly and prevents accidental loosening. In a specific embodiment, such as... Figure 3 As shown, the fastener 30 includes a first protrusion 34 and a second protrusion 35, and a groove is formed between the first protrusion 34 and the second protrusion 35. The assembly of the first wire harness connector 10 and the second wire harness connector 20 is limited and engaged in the groove between the first protrusion 34 and the second protrusion 35.

[0050] In one embodiment, such as Figure 4 The diagram shown is a schematic representation of the fixing structure of the fastener 30 according to an embodiment of the present invention; as shown Figure 5 The diagram shows an application scenario of the footwell cover 4 and connector 50 provided according to an embodiment of the present invention. The vehicle also includes a footwell cover fixing bracket 40 and a connector 50 (in this embodiment, the connector 50 can be a bolt). A groove 41 is formed on the footwell cover fixing bracket 40. The connecting head (e.g., a bolt head) of the connector 50 is engaged with the bottom wall of the groove 41. The connecting rod (e.g., a bolt connecting rod) of the connector 50 passes through the bottom wall of the groove 41 and connects to the vehicle body 2. A fixing member 30 is disposed in the groove 41 and engaged with the connecting head. The vehicle also includes a footwell cover fixing bracket 40 and a connector 50, both of which are disposed in the gap 3 between the vehicle body 2 and the seat 1. The footwell cover fixing bracket 40 is used to connect to the vehicle's footwell cover 4 to stabilize the vehicle's footwell cover 4. A groove 41 is also formed on the footwell cover fixing bracket 40. The connector 50 includes a connecting rod and a connecting head. The connecting rod passes through the floor cover fixing bracket 40 and connects to the vehicle body 2 to lock the floor cover fixing bracket 40 to the vehicle body 2. The connecting head is engaged with the bottom wall of the groove 41. The fixing member 30 is disposed in the groove 41 of the floor cover fixing bracket 40 and engages with the connecting head of the connector 50. In the above-described mating structure, the floor cover fixing bracket 40 and the connector 50 are conventionally installed in the gap 3 between the vehicle body 2 and the seat 1. In this embodiment of the invention, the connecting head in the existing structure is used to limit the fixing member 30 to be installed in the groove 41 of the floor cover 4, which effectively improves the space utilization rate, reduces the height occupied by the wiring harness docking assembly, and further avoids the occurrence of local bulges on the inner bottom surface of the vehicle body 2. In addition, the above connection method does not require additional locking components and does not cause structural damage to the vehicle body 2.

[0051] In one embodiment, the bottom wall of the fastener 30 has a receiving hole 32 for accommodating the connecting head and forming an interference fit with it. An interference fit is a tight fit achieved by having a larger bore diameter than the shaft diameter of one part. During assembly, the part with the larger bore diameter fits onto the part with the smaller shaft diameter, and through the elastic deformation and compressive force of the materials, the two parts are connected more tightly. The fastener 30 of this application has a receiving hole 32 formed on its bottom wall, and the receiving hole 32 is interference-fitted with the connecting head so that the fastener 30 can fit tightly with the connecting head.

[0052] In one embodiment, there are multiple receiving holes 32 and multiple connectors 50, and the positions of the multiple receiving holes 32 correspond one-to-one with the positions of the multiple connectors 50. There are multiple connectors 50, and multiple receiving holes 32 are formed on the bottom wall of the fixing member 30, each corresponding to a connector 50. Each receiving hole 32 is interference-fitted with a connecting head corresponding to a connector 50. This fitting method can make the connection between the foot cover fixing bracket 40 and the vehicle body 2 tighter, and can also make the fit between the fixing member 30 and the connecting head tighter.

[0053] In one embodiment, the depth of the receiving hole 32 is greater than or equal to the height of the connecting head. When the depth of the receiving hole 32 is greater than or equal to the height of the connecting head, the bottom surface of the fastener 30 can fully fit against the foot cover mounting bracket 40, resulting in a tighter connection between the fastener 30 and the foot cover mounting bracket 40. When the depth of the receiving hole 32 is equal to the height of the connecting head, the height of the fastener 30 is such that the connecting head does not protrude from the receiving groove 31, and the bottom wall of the fastener 30 fits against the foot cover mounting bracket 40, with the mounting bracket at its lowest height. Using this structure, the connection between the wiring harness connection assembly and other components of the vehicle can be tighter, and the wiring harness connection assembly requires less installation height.

[0054] In one embodiment, the fastener 30 is made of foam, silicone, or rubber. Soft materials such as foam, silicone, or rubber are elastic, allowing for relatively easy installation even with an interference fit with the connector head of the connector 50. Furthermore, foam, silicone, or rubber are not easily damaged, have low cost, and are convenient for installation and transportation.

[0055] In one embodiment, the outer contour of the assembly of the first wire harness connector 10 and the second wire harness connector 20 is adapted to the shape and size of the inner contour of the receiving groove 31. The adaptation of the outer contour of the assembly to the inner contour of the receiving groove 31 enables the inner wall of the receiving groove 31 to fit fully with the assembly, so as to more stably install the assembly in the receiving groove 31.

[0056] In one specific embodiment, the width of the assembly formed by the first wire harness connector 10 and the second wire harness connector 20 is slightly smaller than the distance between the first protrusion 34 and the second protrusion 35. This allows the assembly to be interference-fitted with the two side walls of the slot when it is installed in the slot, so as to install the assembly more stably.

[0057] In one embodiment, such as Figure 3 As shown, the fastener 30 also has a clearance space 33 for avoiding the first or second wire harness. The first or second wire harness can pass through the clearance space 33 to facilitate the installation of the first or second wire harness and avoid squeezing the first or second wire harness.

[0058] In one embodiment, a vehicle is provided, including a body 2; a seat 1 mounted on the body 2; and the aforementioned wiring harness docking assembly for the vehicle, which includes at least the following advantages:

[0059] The vehicle in this embodiment includes a wiring harness docking assembly, which includes a first wiring harness connector 10, a second wiring harness connector 20, and a fixing member 30. The first wiring harness connector 10 is used to be disposed on a first wiring harness (not shown in the figure) extending from the interior of the vehicle seat 1. The second wiring harness connector 20 is used to be disposed on a second wiring harness (not shown in the figure) extending from the interior of the vehicle body 2 and can be plugged into the first wiring harness connector 10. The fixing member 30 is disposed in the gap 3 between the seat 1 and the body 2 and forms a receiving groove 31. The receiving groove 31 is used to receive the combination of the first wiring harness connector 10 and the second wiring harness connector 20 after plugging. The fastener 30 is installed in the gap 3 between the seat 1 and the body 2. The fastener 30 has a receiving groove 31, which can be used to accommodate the combination formed by the first wire harness connector 10 and the second wire harness connector 20. The combination is fixed in the above manner. The height of the wire harness docking assembly is the height of the fastener 30, which effectively reduces the overall height of the wire harness docking assembly and avoids the occurrence of local bulges on the inner bottom surface of the body 2, so as to facilitate the storage of large items such as suitcases.

[0060] In one specific embodiment, the seat 1 is a magic folding seat 1, which is foldably mounted on the vehicle body 2. A first wiring harness extends from inside the magic folding seat 1, and a first wiring harness connector 10 is disposed at the end of the first wiring harness. A second wiring harness extends from inside the vehicle body 2, and a second wiring harness connector 20 is disposed at the end of the second wiring harness.
