Description

A vehicle body assembly and a vehicle Technical Field

[0001] This application relates to vehicle technology, and more particularly to a body assembly and a vehicle. Background Technology

[0002] Compared to the rotating rear doors of passenger cars, sliding doors are a common feature in multi-purpose vehicles (MPVs). The wiring harnesses associated with sliding doors need to be designed to accommodate a wide range of reciprocating opening and closing movements, requiring specialized motion connection and protection structures.

[0003] In related technologies, the fixing part of the connecting harness corresponding to the vehicle body is generally designed at the rear edge of the door sill. The connecting harness needs to be stored and organized in a separate area on the vehicle body. Therefore, the vehicle body needs to be designed with steps to block the connecting harness from being exposed, which occupies height space, raises the floor height of the vehicle, restricts the overall vehicle design layout, and is also not conducive to passengers getting in and out. Summary of the Invention

[0004] This application provides a vehicle body assembly and a vehicle to solve the technical problem in the related art of the wiring harnesses connecting the vehicle body and the doors occupying height space.

[0005] On one hand, this application provides a vehicle body assembly, including:

[0006] The vehicle body and the door slidably connected to the vehicle body;

[0007] The first bracket is connected to the vehicle door;

[0008] The second bracket is connected to the vehicle body.

[0009] A flexible component is slidably disposed on the floor plane of the vehicle body, with one end of the flexible component connected to the first bracket and the other end connected to the second bracket;

[0010] A connecting harness is threaded through the first bracket, the flexible component, and the second bracket, and is used to connect the vehicle body and the door.

[0011] When the car door slides relative to the car body, the first bracket and the flexible component slide synchronously relative to the second bracket along the floor plane of the car body.

[0012] In some possible implementations, a connector is also included, the connector comprising a first connecting portion for connecting the door and a second connecting portion for connecting the first bracket, the first connecting portion extending upward relative to the second connecting portion along the height direction of the vehicle body, and the second connecting portion being slidably connected to the vehicle body.

[0013] In some possible implementations, a slide rail section is provided on the floor of the vehicle body, and the second connecting part is provided with a pulley that is slidably connected to the slide rail section;

[0014] The first bracket, the flexible component, and the second bracket are arranged parallel to the slide rail section, and the first bracket, the flexible component, and the second bracket are all located below the slide rail section.

[0015] In some possible implementations, the vehicle body is provided with a cover plate, which together with the floor of the vehicle body forms an accommodating space. The first bracket, the flexible component, and the slide rail section are all located in the accommodating space. The cover plate is provided with an opening for the connecting harness to pass through.

[0016] In some possible implementations, the first support and the flexible component are rotatably connected by a first limiting member, and the second support and the flexible component are rotatably connected by a second limiting member;

[0017] The first limiting member is used to limit the rotation angle between the first bracket and the flexible component, and the second limiting member is used to limit the rotation angle between the second bracket and the flexible component.

[0018] In some possible implementations, the first bracket includes a first housing for passing through the connecting wire harness, and the inner diameter of the first housing gradually increases along the direction of the first housing toward the vehicle door.

[0019] In some possible implementations, the second bracket includes a second housing for passing through the connecting wire harness, the second housing having an upward slot and being bent, the slot width gradually increasing along the direction of the second housing toward the vehicle door.

[0020] In some possible implementations, the first housing has a wire harness bundling and fixing plate on the side facing the door, and the second housing has a wire harness bundling opening on the side facing the vehicle body.

[0021] In some possible implementations, the flexible component is a hollow flexible hinge, which includes a plurality of hinged members that are rotatably connected to each other, and each of the hinged members is provided with a limiting portion for limiting the rotation angle of adjacent hinged members.

[0022] On the other hand, embodiments of this application also provide a vehicle, including a vehicle body and a body assembly as described in any of the preceding claims connected to the vehicle body.

[0023] The vehicle body assembly and vehicle provided in this application have a first bracket connected to the door and a second bracket connected to the vehicle body. The first bracket and the second bracket are connected by a flexible component. Since the flexible component is slidably disposed on the floor plane of the vehicle body, when the door slides relative to the vehicle body, the first bracket and the flexible component slide synchronously relative to the second bracket along the floor plane of the vehicle body. This constrains the wiring harness and related transmission structure to the horizontal plane. The unfolding and retraction path of the wiring harness forms a planar geometric mapping with the sliding trajectory of the door. There is no need to design additional steps to cover the wiring harness, which reduces the encroachment of the wiring harness on the floor height and longitudinal space, and helps to improve the overall longitudinal space utilization effect.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0040] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0041] As mentioned in the background section, the wiring harness on the sliding door of an MPV needs to be designed at the rear edge of the door sill to accommodate passenger access space. This harness is typically arranged vertically along the sliding door rail. This design results in a larger overall height space requirement, raising the overall vehicle floor height. The door panel needs to be specially designed with recesses to store the wiring harness, and the vehicle body also needs to be designed with steps to cover the exposed wiring harness. The step structure restricts the overall vehicle design layout and affects passenger access.

[0042] Based on the above description, one or more embodiments of this application provide a vehicle body assembly and a vehicle. The following description, in conjunction with the accompanying drawings, illustrates the solutions of the embodiments of this application.

[0043] As shown in Figure 1, this application embodiment provides a vehicle body assembly, including a vehicle body 100 and a door 200 slidably connected to the vehicle body 100; wherein, a first bracket 301 is connected to the door 200; a second bracket 302 is connected to the vehicle body 100; a flexible component 303 is slidably disposed on the floor plane of the vehicle body 100, one end of the flexible component 303 is connected to the first bracket 301, and the other end is connected to the second bracket 302; a connecting harness 700 passes through the first bracket 301, the flexible component 303, and the second bracket 302, and is used to connect the vehicle body 100 and the door 200; when the door 200 slides relative to the vehicle body 100, the first bracket 301 and the flexible component 303 slide synchronously relative to the second bracket 302 along the floor plane of the vehicle body 100.

[0044] As can be seen from the above description, the vehicle assembly provided in this application embodiment places the first bracket 301, the second bracket 302 and the flexible component 303 on the same horizontal plane. The offset path of the connecting harness 700 as it slides with the door 200 is always on the horizontal plane and does not encroach on the upper space of the vehicle body 100, thereby eliminating the need to design steps on the vehicle body 100 and effectively improving the longitudinal space utilization of the vehicle body 100.

[0045] In the embodiments of this application, the terms "horizontal" and "vertical" are used with reference to the vehicle direction. The top and bottom of the vehicle body 100 are slidably connected to the top and bottom of the door 200, and the plane of the door 200 remains parallel to the side of the vehicle body during the sliding process.

[0046] The door 200 and the vehicle body 100 are communicatively connected via a wiring harness 700. The vehicle body 100 provides power to the electric drive structure of the door 200 through the wiring harness 700, or enables signal interaction between the vehicle body and the door 200 through the wiring harness 700. The connections between the wiring harness 700 and the door 200, and between the wiring harness 700 and the vehicle body 100, can be arranged according to relevant technologies, and will not be described again in this embodiment.

[0047] As shown in Figures 1 and 2, in some embodiments, the vehicle body assembly further includes a connector 400. The connector 400 includes a first connecting portion 401 that connects to the door 200 and a second connecting portion 402 that connects to the first bracket 301. The first connecting portion 401 extends upward relative to the second connecting portion 402 along the height direction of the vehicle body 100, and the second connecting portion 402 is slidably connected to the vehicle body 100.

[0048] In the above embodiment, the connector 400 can be an integral metal casting. The connector 400 is used to fix the first bracket 301 to the car door 200. The first connecting part 401 of the connector 400 is adapted to the inner sheet metal of the car door 200 to form a groove. The first connecting plate is fitted into the inner sheet metal of the car door 200 and a fixed connection is formed by bolts that pass through both.

[0049] The second connecting part 402 of the connector 400 is fixedly connected to the first bracket 301. Since the first connecting part 401 extends vertically upward relative to the second connecting part 402, the connecting harness 700 passes through the first bracket 301 and the connector 400 and is guided by the connector 400 to the connection port position of the door 200. The extension design of the first connecting part 401 forms a compensation space in the vertical direction. When the door 200 slides relative to the body 100, the first bracket 301 and the flexible component 303 both slide in the horizontal direction. The connecting harness 700 is guided and fixed by the connector 400 fixed on the side wall of the door 200, reducing the occupation of the longitudinal space of the body 100.

[0050] Furthermore, a slide rail section 500 is provided on the floor of the vehicle body 100, and a pulley 403 is provided on the second connecting part 402 that is slidably connected to the slide rail section 500; the first bracket 301, the flexible component 303 and the second bracket 302 are arranged parallel to the slide rail section 500, and the first bracket 301, the flexible component 303 and the second bracket 302 are all located below the slide rail section 500.

[0051] In the above embodiment, the first bracket 301 and the connector 400 are connected, and the connector 400 is slidably connected to the slide rail section 500. Therefore, when the door 200 slides relative to the body body 100, the connector 400 drives the first bracket 301 and the flexible component 303 to move horizontally in sync. The first connecting part 401 of the connector 400 occupies part of the longitudinal space as the door 200 slides. However, the first bracket 301, the flexible component 303 and the second bracket 302 are all located below the slide rail section 500. Thus, the connecting wire harness 700 can be prevented from encroaching on the upper space of the body body 100. There is no need to set a step on the body body 100 to accommodate the connecting wire harness 700, which is conducive to maintaining the aesthetics of the body body 100.

[0052] In some embodiments, a cover plate 600 is provided on the vehicle body 100. The cover plate 600 and the floor of the vehicle body 100 together form an accommodating space. The first bracket 301, the flexible component 303 and the slide rail section 500 are all located in the accommodating space. The cover plate 600 is provided with an opening for connecting the wire harness 700 to pass through.

[0053] In the above embodiment, the cover plate 600 is fixedly connected to the floor of the vehicle body 100. The cover plate 600 covers the floor of the vehicle body 100, which on the one hand can cover the first bracket 301, the flexible component 303 and the slide rail section 500, maintaining the overall appearance of the vehicle body 100. On the other hand, the cover plate 600 can also provide an additional mounting base for the second bracket 302 and the connector 400. The second bracket 302 and the connector 400 can be fixed to the cover plate 600 by through bolts, which helps to fix the second bracket 302 and the connector 400.

[0054] It should be noted that the first bracket 301, the flexible component 303, and the second bracket 302 are all located below the slide rail section 500. The vehicle body 100 does not have any supporting components for fixing the slide rail section 500 on the sliding path of the first bracket 301 and the flexible component 303. Instead, relevant components for supporting and fixing the slide rail section 500, such as bolts or support columns, are provided in the area of ​​the sliding path of the first bracket 301 and the flexible component 303.

[0055] As shown in Figure 3, in some embodiments, the flexible component 303 may be a flexible hinge in the related art. The flexible hinge is hollow inside for passing through the connecting wire harness 700. Here, the flexible hinge includes a plurality of twisted members that are rotatably connected to each other. The plurality of twisted members are connected end to end, and each twisted member is provided with a limiting part for limiting the rotation angle of adjacent twisted members.

[0056] The aforementioned limiting part can prevent the flexible component 303 from bending at a large angle, thereby preventing the connecting wire harness 700 inside the flexible component 303 from being bent and damaged, affecting the transmission effect.

[0057] Specifically, two adjacent hinged parts are rotatably connected by a common pivot. The limiting part is a boss at the end of the hinged part. During the relative rotation of the hinged parts, the limiting part blocks large-angle rotational displacement. A baffle is provided on the outer wall of the hinged parts. When the door 200 and the body 100 are in the closed state, the flexible part 303 is in the bent state. When the door 200 slides relative to the body 100 to the open state, the flexible part 303 is rotated and straightened by the first bracket 301. The baffle covers the connecting wire harness 700 inside the flexible part 303, thereby avoiding direct exposure of the connection display and affecting the aesthetics.

[0058] As shown in Figures 3 to 5, in some embodiments, the first support 301 and the flexible component 303 are rotatably connected by a first limiting member 304, and the second support 302 and the flexible component 303 are rotatably connected by a second limiting member 305; the first limiting member 304 is used to limit the rotation angle between the first support 301 and the flexible component 303, and the second limiting member 305 is used to limit the rotation angle between the second support 302 and the flexible component 303.

[0059] One end of the first bracket 301 and the first limiting member 304 are rotatably connected by a common pivot. The hinge at the end of the flexible component 303 and the other end of the first limiting member 304 are rotatably connected by a common pivot. The limiting angle of the first limiting member 304 can be flexibly arranged according to the application scenario. For example, a fan-shaped limiting groove 3041 is constructed at the end of the first limiting member 304 facing the first bracket 301. The end of the first bracket 301 is constructed as an arc. The end of the first bracket 301 is inserted into the limiting groove 3041. The end of the first bracket 301 can rotate in the limiting groove 3041, but the rotation is blocked by the side wall of the limiting groove 3041, thereby realizing the angle limitation of the first limiting member 304.

[0060] Similarly, the twisted joint of the first limiting member 304 and the flexible member 303, the twisted joint of the second limiting member 305 and the second support 302, the twisted joint of the second limiting member 305 and the flexible member 303, and the angle limiting method between two adjacent twisted joints of the flexible member 303 can all be set in the manner described above, and will not be repeated in this embodiment.

[0061] For example, when the door 200 is closed relative to the vehicle body 100, the rotation angle of the first limiting member 304 relative to the flexible component 303 is relatively large. When the door 200 is open relative to the vehicle body 100, the rotation angle of the first limiting member 304 relative to the flexible component 303 is relatively small. During the process of the door 200 switching from the closed state to the open state, the rotation angle of the second limiting member 305 relative to the second bracket 302 first gradually decreases and then gradually increases. Here, the specific limitation range of the rotation angle can be set with reference to relevant factors such as the sliding length of the door 200, the length of the flexible hinge, and the distance between the first bracket 301 and the second bracket 302 in the lateral direction of the vehicle body. This embodiment of the application does not impose an absolute limitation on this.

[0062] By setting the first limiting member 304 and the second limiting member 305, the connecting wire harness 700 can be prevented from being excessively bent at the positions of the first bracket 301 and the second bracket 302, thereby avoiding damage to the connecting wire harness 700.

[0063] As shown in Figure 4, the first bracket 301 includes a first housing 3012 for passing through the connecting wire harness 700. Along the direction of the first housing 3012 toward the door 200, the inner diameter of the first housing 3012 gradually increases.

[0064] The first housing 3012 and the second connecting part 402 of the connector 400 are rotatably connected by a common pivot. The first housing 3012 is equipped with a connecting wire harness 700. Along the direction of the first housing 3012 toward the door 200, the inner diameter of the first housing 3012 gradually increases, which can provide a certain buffer space for the connecting wire harness 700 located in the first housing 3012, thereby avoiding the connecting wire harness 700 from being squeezed and damaged due to excessive tightness in the first housing 3012.

[0065] Furthermore, a wire harness bundling and fixing plate 3011 is constructed on the side of the first housing 3012 facing the door 200. The wire harness bundling and fixing plate 3011 is T-shaped, which facilitates bundling and fixing the wire harness on the first housing 3012.

[0066] As an alternative implementation, as shown in FIG5, the second bracket 302 includes a second housing for passing through the connecting wire harness 700. The second housing has an upward slot and is bent. The width of the slot gradually increases along the direction of the second housing toward the door 200.

[0067] The twisted parts at the ends of the second housing and the flexible component 303 are rotatably connected by a common pivot. The connecting wire harness 700 is installed inside the second housing. Along the direction of the second housing toward the door 200, the width of the slot in the second housing gradually increases. This design allows the connecting wire harness 700 located inside the second housing to have a certain buffer space, thereby avoiding excessive tightness of the connecting wire harness 700 inside the second housing and causing squeezing damage.

[0068] Furthermore, the second housing has a wire harness bundling opening 3021 on the side facing the vehicle body 100. The wire harness bundling opening 3021 is T-shaped, which facilitates bundling and fixing the wire harness on the second housing.

[0069] In addition, both the first housing 3012 and the second housing are designed with bending. The bending design enables the connecting wire harness 700 located in the first housing 3012 and the second housing to form a smoother transition and transport, thereby avoiding large-angle bends in the connecting wire harness 700 as much as possible and preventing bending damage to the connecting wire harness 700.

[0070] An exemplary working process of the vehicle body assembly in this application embodiment is as follows:

[0071] When the door 200 is closed relative to the body 100, the flexible component 303 and the first bracket 301 are located on the left side of the position shown in Figure 1. The bending angle of the first bracket 301 and the flexible component 303 is relatively large. As the door 200 slides open relative to the body 100, the connector 400 connected to the door 200 drives the first bracket 301 and the flexible component 303 to move to the right in sync. The bending angle of the first bracket 301 and the flexible component 303 decreases. The first bracket 301 and the flexible component 303 are both dragged to the right side below the slide rail section 500. Throughout the process, the first bracket 301, the second bracket 302 and the flexible component 303 all slide in the same horizontal direction.

[0072] This application also provides a vehicle, including a vehicle body and a body assembly as described in any of the above embodiments connected to the vehicle body. Since the vehicle includes the body assembly as described in any of the above embodiments, it has all the advantages of a body assembly.
