[0001] The invention relates to the field of vehicle manufacturing, and in particular to a wire duct and a vehicle. Background Art

[0002] With the rapid development of modern society and the increasing demand of consumers for living comfort, cars, as a means of transportation, have become a necessary need in people's lives.

[0003] During the automobile assembly process, due to the air tightness of the vehicle body, holes cannot be drilled in the rear section of the longitudinal beam inner panel to weld nuts. Only end convex welding bolts can be set on the rear section of the longitudinal beam inner panel. Due to the different mounting surfaces provided by the vehicle body, the wire trough can only be installed to the longitudinal beam inner panel through the open clamping structure opened thereon.

[0004] However, the method of clamping the open clamping structure with the end face projection welding bolt cannot ensure assembly consistency due to the open design of the clamping structure, and the connection between the two is relatively loose and lacks stability. Summary of the invention

After the assembly is completed, due to the limiting effect of the first limit plate and the second limit plate, the end face projection welding bolt can be prevented from being separated from the fixed space, thereby improving the connection stability between the wire trough and the longitudinal beam inner plate.

[0008] Furthermore, the top surfaces of the first end and the second end are respectively concave to form a first bearing groove and a second bearing groove, and one end of the first limiting plate facing away from the second limiting plate is connected to the first bearing groove through a first connecting plate, and one end of the second limiting plate facing away from the first limiting plate is connected to the second bearing groove through a second connecting plate.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] In the first aspect, the embodiment 1 of the present invention provides a wire duct for connecting the longitudinal beam inner plate 10 of the vehicle body, see Figures 5 to 7 The longitudinal beam inner plate 10 is provided with an end projection welding bolt 110, and the wire trough includes a body 20 and a clamping plate 30 provided on the body 20, and the end of the clamping plate 30 facing away from the body 20 is concave to form a clamping groove 310 corresponding to the end projection welding bolt 110, and the clamping groove 310 penetrates the clamping plate 30 to separate the end of the clamping plate 30 facing away from the body 20 into a first end 320 and a second end. In the traditional assembly method, the assembly work between the wire trough and the longitudinal beam inner plate 10 is completed by clamping the end projection welding bolt 110 into the clamping groove 310.

[0029] See also Figures 1 to 4 The wire trough also includes a first limiting plate 40 and a second limiting plate, the first limiting plate 40 is connected to the first end 320, the second limiting plate is connected to the second end, the first limiting plate 40 and the second limiting plate are arranged opposite to each other, one end of the first limiting plate 40 is bent and extended toward the second limiting plate, and one end of the second limiting plate is bent and extended toward the first limiting plate 40, so that the first limiting plate 40, the second limiting plate and the bottom of the clamping groove 310 form a fixed space 50 adapted to the end face projection welding bolt 110. It can be understood that the first limiting plate 40 and the second limiting plate are both arc-shaped, and the bottom of the clamping groove 310 is also arc-shaped.

[0030] By respectively arranging the first limiting plate 40 and the second limiting plate on the opposite sides of the clamping groove 310, one end of the first limiting plate 40 is bent and extended toward the second limiting plate, and one end of the second limiting plate is extended toward the first limiting plate 40. It can be understood that one end of the first limiting plate 40 toward the second limiting plate and one end of the second limiting plate toward the first limiting plate 40 are both located above the clamping groove 310, and a positioning structure for the end face projection welding bolt 110 is formed at the clamping groove 310, so that after the end face projection welding bolt 110 enters the fixed space 50 along the clamping groove 310, the assembly between the wire trough and the longitudinal beam inner plate 10 is completed. By setting the positioning structure, the consistency of the assembly is ensured, and after the assembly is completed, due to the limiting effect of the first limiting plate 40 and the second limiting plate, the end face projection welding bolt 110 can be prevented from being separated from the fixed space 50, thereby improving the connection stability between the wire trough and the longitudinal beam inner plate 10.

[0031] Furthermore, the top surfaces of the first end 320 and the second end are respectively concave to form a first bearing groove 321 and a second bearing groove, and the first bearing groove 321 is arranged opposite to the second bearing groove. The end of the first limiting plate 40 facing away from the second limiting plate is connected to the first bearing groove 321 through the first connecting plate 60, and the end of the second limiting plate facing away from the first limiting plate 40 is connected to the second bearing groove through the second connecting plate. By setting the first bearing groove 321 and the second bearing groove, the overall weight of the clamping plate 30 can be reduced, and then by setting the first connecting plate 60 and the second connecting plate, the stable connection between the first limiting plate 40 and the second limiting plate and the clamping plate 30 is ensured.

[0032] One end of the first connecting plate 60 facing away from the first limiting plate 40 is slidably connected to the bottom of the first bearing groove 321, and one end of the second connecting plate facing away from the second limiting plate is slidably connected to the bottom of the second bearing groove. It can be understood that the sliding directions of the first connecting plate 60 and the second connecting plate are located on the same horizontal line. Through the sliding connection between the first connecting plate 60 and the first end 320 and the sliding connection between the second connecting plate and the second end, when assembly is required, the first connecting plate 60 and the second connecting plate can be slid in opposite directions, thereby causing the first limiting plate 40 to move toward one end of the second limiting plate and the second limiting plate to move toward the first limiting plate 4 0 is disengaged from the top of the clamping groove 310, preventing the first limiting plate 40 and the second limiting plate from limiting the end projection welding bolt 110 from entering the clamping groove 310, and when the end projection welding bolt 110 abuts against the bottom of the clamping groove 310, the first connecting plate 60 and the second connecting plate slide in opposite directions, thereby causing the first limiting plate 40 to be positioned toward one end of the second limiting plate and the second limiting plate to be positioned toward one end of the first limiting plate 40 to be re-placed above the clamping groove 310, the first limiting plate 40, the second limiting plate and the bottom of the clamping groove 310 enclose the fixed space 50, and the end projection welding bolt 110 is limited in the fixed space 50.

[0033] Specifically, the bottom of the first bearing groove 321 is concave to form a slide groove 322, and a slider 324 is slidably connected in the slide groove 322. The opposite side walls of the slide groove 322 are respectively connected to the first blocking block 323 and the second blocking block. It can be understood that the slider 324 is located between the first blocking block 323 and the second blocking block and the bottom of the slide groove 322. By setting the first blocking block 323 and the second blocking block, the slider 324 can be prevented from disengaging from the slide groove 322, causing the first limiting plate 40 to disengage from the first end 320. The first blocking block 323 and the second blocking block are arranged opposite to each other, and the first blocking block 323 and the second blocking block have the same length as the slide groove 322.

[0034] A limiting space is formed between the first blocking block 323 and the second blocking block, and a protrusion 325 is slidably arranged in the limiting space. The slider 324 is connected to the end of the first connecting plate 60 facing away from the first limiting plate 40 through the protrusion 325, thereby realizing the sliding connection between the first limiting plate 40 and the first end 320. Furthermore, a sliding rod 70 is connected between the two opposite side walls of the first bearing groove 321, and the first connecting plate 60 is sleeved outside the sliding rod 70. By providing the sliding rod 70, the first connecting plate 60 can be matched with the sliding groove 322 to realize the sliding of the first connecting plate 60, and by providing the sliding rod 70, the stability of the overall structure can be improved, and the sliding direction of the first connecting plate 60 can be limited at multiple positions. The outer sleeve of the slide bar 70 is connected with a first spring 80 and a second spring. The first spring 80 and the second spring are located on opposite sides of the first connecting plate 60, and opposite ends of the first spring 80 and the second spring are respectively connected to the side wall of the first bearing groove 321 and the first connecting plate 60. By providing the first spring 80 and the second spring, the first limit plate 40 can be automatically reset while further improving the stability of the overall structure. Specifically, when the end projection welding bolt 110 enters the clamping groove 310, the first limit plate 40 is slid away from the second limit plate. At this time, the first limit plate 40 squeezes the first spring 80 and drives the second spring to stretch. After the end projection welding bolt 110 abuts against the bottom of the clamping groove 310, the first limit plate 40 is released, and the first spring 80 and the second spring rebound, thereby resetting the first limit plate 40 and completing the limit of the end projection welding bolt 110. The second connecting plate is provided with the same structure to achieve the same function, which will not be repeated here.

[0035] A first inclined surface 90 is formed on a side of the first end 320 facing the second end, and an acute angle is formed between the first inclined surface 90 and a side of the first end 320 facing away from the second end. A second inclined surface is formed on a side of the second end facing the first end 320, and an acute angle is formed between the second inclined surface and a side of the second end facing away from the first end 320, that is, the first inclined surface 90 and the second inclined surface are overall inverted eight-shaped structures, and the first inclined surface 90 and the second inclined surface are both located at the opening of the snap-fit ​​groove 310. By providing the first inclined surface 90 and the second inclined surface, the opening area of ​​the snap-fit ​​groove 310 is enlarged, so that the end face projection welding bolt 110 can enter the snap-fit ​​groove 310 more easily, that is, the first inclined surface 90 and the second inclined surface can play a guiding role when the end face projection welding bolt 110 enters the snap-fit ​​groove 310, guiding the end face projection welding bolt 110 along the first inclined surface 90 or the second inclined surface and the snap-fit ​​groove 310.
