DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0050] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the embodiment of the present application provides a wire harness assembly applied to a seat slide rail, which comprises a flexible continuous carrier 1 and a wire harness box 2, the flexible continuous carrier 1 comprises a pipe body, an inner space of the pipe body forms a wire harness containing space 11, the pipe body is provided with an auxiliary part for enabling the flexible continuous carrier 1 to bend, the existence of the auxiliary part enables the flexible continuous carrier 1 to bend when being stretched out or retracted, thereby weakening the bending stress caused by bending, one part of the pipe body is located in the wire harness box 2 and fixed with the wire harness box 2, thereby realizing fixing the flexible continuous carrier 1 in the wire harness box 2, one end of the pipe body is stretched out from a wire outlet end of the wire harness box 2 and used for connecting an upper rail assembly 3, and a first limiting guide part 10 extending along the pipe length and used for adapting to a second limiting guide part 40 on a lower rail assembly 4 is arranged on an outer wall surface of the pipe body.

[0051] According to the second limiting guide part 40 on the lower rail assembly 4, the embodiment of the present application arranges the adapted first limiting guide part 10 on the pipe body of the flexible continuous carrier 1, and enables one of the second limiting guide part 40 and the first limiting guide part 10 to stretch into the other and relatively move, so that the limiting and guiding of the flexible continuous carrier 1 are realized under the action of the two adapted guide parts, the flexible continuous carrier 1 can slide along the axial direction of the lower rail assembly 4 synchronously with the upper rail assembly 3, and the power supply demand of the seat in the long-distance adjustment process is met. Meanwhile, in the embodiment, the reset of the flexible continuous carrier 1 is realized while the limiting and guiding are realized by the adapted guide parts, and a spring reset mechanism is not needed for reset, so that the wire harness containing space in the pipe body can be increased, the pipe body is sufficient to contain the power supply wire harness required by many functions, and the stable power supply demand of the seat with multiple functions is met.

[0052] Since the flexible continuous carrier 1 in the embodiment adopts the one-piece pipe body design instead of the multi-section type drag chain, the disconnection can be avoided while the wire harness protection is realized, and since the spring reset mechanism is not needed, the space is saved and the weight is reduced.

[0053] It can be understood that there are various fixing modes of the pipe body and the wire harness box 2, such as the existing modes, for example, adhesion, setting of a fixed joint and the like.

[0054] A new fixing mode is provided in the embodiment, and the fixed joint is not needed, specifically, a clamping part 20 is arranged in the wire harness box 2, one end of the pipe body located in the wire harness box 2 is clamped with the clamping part 20 through at least one auxiliary part, thereby realizing fixing the flexible continuous carrier 1 in the wire harness box 2, the installation of the flexible continuous carrier 1 is realized by clamping the auxiliary part on the pipe body with the clamping part 20 on the wire harness box 2, and the fixed joint for the flexible continuous carrier 1 is not needed, so that the weight can be further reduced.

[0055] It can be understood that the flexible continuous carrier 1 has various forms.

[0056] For example, as shown in Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , the pipe body is a corrugated pipe, and the auxiliary part is a valley part of the corrugated pipe. As shown in Figure 6 , when the corrugated pipe is used, the clamping part 20 is in the form of a plate tooth, which is engaged with the peaks and valleys of the corrugated pipe, thereby achieving clamping. It can be seen that the corrugated pipe is installed and fixed on the wire harness box 2 by using the inherent features of the outer wall of the corrugated pipe, and a separate fixing connector for the corrugated pipe can be avoided, which not only facilitates installation, but also reduces weight.

[0057] For example, as shown in Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , the pipe body is a flexible pipe with a smooth outer wall, and the auxiliary part is a notch 12 or groove on both sides of the flexible pipe. The notch 12 or groove can have a V-shaped or other shape. In this embodiment, a notch 12 or groove can be provided on a commonly used flexible pipe to weaken the bending stress caused by bending, thereby ensuring the bendability of the flexible pipe. Such a flexible pipe can be directly selected from commercially available pipe bodies and processed with a notch 12 or groove. At this time, the clamping part 20 can include a plurality of teeth arranged at intervals, which extend into the notch 12 or groove to achieve fixation between the two.

[0058] It can be understood that the cross-sectional shape of the pipe body can also have various options. For example, as shown in Figure 7 and Figure 8 , the cross-section of the pipe body is circular.

[0059] For example, as shown in Figure 9 , Figure 11 , Figure 13 and Figure 19 , the cross-section of the pipe body is square. The square can also be a special square. The use of a square can maximize the use of space to load the wire harness.

[0060] In order to achieve the limiting and guiding of the flexible continuous carrier 1, the application provides the specific structure of the first limiting and guiding part 10 and the second limiting and guiding part 40. That is, one of the first limiting and guiding part 10 and the second limiting and guiding part 40 is a protrusion, and the other is a groove or a step. Through the cooperation of the protrusion and the groove or the step, the limiting and guiding of the flexible continuous carrier 1 are achieved.

[0061] It can be understood that when the first limiting and guiding part 10 is a protrusion, the second limiting and guiding part 40 is a groove or a step; when the first limiting and guiding part 10 is a groove or a step, the second limiting and guiding part 40 is a protrusion.

[0062] For example, as an example, see Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 , wherein the second limiting and guiding part 40 is a protrusion, and in Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 , the first limiting and guiding part 10 is a groove, and in Figure 11 、 Figure 12 、 Figure 17 、 Figure 18 , the first limiting and guiding part 10 is a step.

[0063] It can be understood that for the groove of the first limiting and guiding part 10, the groove can be externally provided on the surface of the pipe body (as shown in Figure 7 、 Figure 8 ), or the groove can be internally recessed on the surface of the pipe body (as shown in Figure 13 ). It can be understood that compared with the groove internally recessed on the surface of the pipe body, the externally provided groove does not occupy the wire harness containing space 11, and thus has greater wire harness containing capacity.

[0064] It can be understood that compared with Figure 9 and Figure 11 , when the first limiting and guiding part 10 adopts the groove, the first limiting and guiding part 10 adopts the step, which can expand the wire harness containing space 11, and thus has greater wire harness containing capacity.

[0065] For example, as an example, seeFigure 19 As shown in the figure, the second limiting guide part 40 is a groove, and the first limiting guide part 10 is a protrusion.

[0066] As a preferred example, referring to Figure 7 As shown in the figure, the second limiting guide part 40 is a protrusion, which is a folded edge of the lower rail assembly 4.

[0067] Further, the first limiting guide part 10 can be located at various positions of the pipe body, such as the top, bottom or side of the pipe body.

[0068] For example, as a preferred example, the first limiting guide part 10 can be located at the top of the pipe body, referring to Figure 7 As shown in the figure, the second limiting guide part 40 is a protrusion arranged vertically.

[0069] For another example, as a preferred example, the first limiting guide part 10 can be located at the side of the pipe body, referring to Figure 19 As shown in the figure, the first limiting guide part 10 is a protrusion arranged at the side of the pipe body, and the second limiting guide part 40 is a groove arranged on the side wall of the lower rail assembly 4.

[0070] Compared with the first limiting guide part 10 located at the top of the pipe body, the first limiting guide part 10 located at the side of the pipe body has the advantage of preventing the flexible continuous loading body 1 from being separated from the lower rail assembly 4 due to the force in the Z direction in the whole vehicle coordinate system. Specifically, referring to Figure 16 As shown in the figure, during use, when the flexible continuous loading body 1 is subjected to a downward pressure, the first limiting guide part 10 is separated from the second limiting guide part 40 due to the downward deformation of the flexible continuous loading body 1, so that the flexible continuous loading body 1 is separated from the lower rail assembly 4. When the first limiting guide part 10 is located at the side of the pipe body, referring to Figure 19 As shown in the figure, when the flexible continuous loading body 1 is subjected to a downward pressure, although the flexible continuous loading body 1 tends to deform downward, the downward deformation has little or no effect on the combination of the first limiting guide part 10 and the second limiting guide part 40 because they are matched at the side, so that the flexible continuous loading body 1 can be prevented from being separated from the lower rail assembly 4.

[0071] Referring to Figure 2 and Figure 20 As shown in the figures, the pipe body is connected with a wire harness connector 13, and the wire harness connector 13 is provided with a recess 130, and the width of the recess 130 gradually expands in the direction close to the upper rail assembly 3.

[0072] It can be understood that, in the assembly process of the pipe body and the lower rail assembly 4, the pipe body is first inserted and matched with the second limiting guide part 40 through the recess 130 provided in the wire harness connector 13. Therefore, the width of the recess 130 provided in the wire harness connector 13 is gradually expanded along the direction close to the upper rail assembly 3, which can absorb the installation error and ensure that the pipe body can smoothly enter the inside of the lower rail assembly 4, and smoothly realize the pulling-out and retracting function of the power supply wire harness.

[0073] Referring to Figure 1 and Figure 2 It can be understood that, in the assembly process of the pipe body and the lower rail assembly 4, the pipe body is first inserted and matched with the second limiting guide part 40 through the recess 130 provided in the wire harness connector 13. Therefore, the width of the recess 130 provided in the wire harness connector 13 is gradually expanded along the direction close to the upper rail assembly 3, which can absorb the installation error and ensure that the pipe body can smoothly enter the inside of the lower rail assembly 4, and smoothly realize the pulling-out and retracting function of the power supply wire harness.
