Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an instrument wiring harness protection box, a dashboard component and a vehicle. Background Art

[0002] The development of new energy vehicles is inseparable from the wiring harness that transmits power and signals. The wiring harness can realize the transmission of power and control signals between the battery, the vehicle controller, and various controllers inside and outside the vehicle. With the gradual improvement of the on-board functions and safety performance of new energy vehicles and the continuous application of intelligent technology, the number of controllers and sensors in the instrument panel has also increased significantly. The energy and signal transmission of various electrical components has led to the increasing complexity of the instrument wiring harness circuit, and the trunk wire diameter of the instrument wiring harness has also increased. However, the wiring harness layout space has been reduced due to the increase in other electrical components, resulting in difficulties in assembly in some narrow locations, or even difficult to assemble. How to solve the problem of the trunk direction of the larger wire diameter has become a crucial task in the instrument wiring harness development module.

[0003] For example, a wire protection box introduced in CN220742941U is designed to solve this problem. The wire protection box adds a wire harness outlet to constrain the direction of the wire harness. The wire protection box is synchronously provided with a tie hole to match the tie to fix the wire harness. The wire protection box is fixed to the instrument panel with bolts. The above solution can solve the problem of instrument harnesses with horizontal orientation, but cannot solve the problem of instrument harnesses with vertical orientation, and is not suitable for situations where the outlet positions are more scattered.

DETAILED DESCRIPTION

[0025] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0026] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] In one embodiment, see Figures 1 to 5 As shown, an instrument harness protection box is provided, which is installed on the crossbeam assembly of the instrument panel assembly of the automobile, and includes a bottom wall 1 and two oppositely arranged side walls 2 connected to the bottom wall 1, that is, the cross section of the instrument harness protection box is U-shaped. The bottom wall 1 and the two side walls 2 enclose a harness channel, and the two ends of the harness channel are respectively an inlet end 3 and an outlet end 4. The inlet end 3 and the crossbeam assembly 12 enclose a channel for accommodating the harness to pass through, and the direction of the inlet end 3 is the same as that of the crossbeam assembly 12; the inlet end 3 and the outlet end 4 are smoothly transitionally connected by a connecting section 5, and the outlet end 4 is arranged downward or obliquely downward.

[0028] Since the inlet terminal 3 and the crossbeam assembly 12 form a channel for the wire harness to pass through, after the installation of the instrument wire harness protection box, it cooperates with the crossbeam assembly 12 to surround the wire harness on all sides, without the need to set up an additional cover structure, and can better fix and protect the wire harness. And since the direction of the inlet terminal 3 is the same as that of the crossbeam assembly 12, the inlet terminal 3 and the outlet terminal 4 are smoothly connected by the connecting section 5, and the outlet terminal 4 is arranged downward or obliquely downward, that is, the inlet direction is the same as the direction of the crossbeam assembly 12, and the outlet direction is downward or obliquely downward, which fully utilizes the space of the instrument panel assembly and meets the more diverse routing requirements of the instrument panel wire harness.

[0029] It should be noted that the wiring harness channels are all polished to make the surfaces of the wiring harness channels smooth to avoid damage to the wiring harness.

[0030] In a preferred embodiment, see Figure 1 As shown, the connecting section 5 includes a first connecting section 51, a second connecting section 52, and an arc-shaped connecting section 53 connecting the first connecting section 51 and the second connecting section 52. The first connecting section 51 is arranged obliquely downward, the upper end of the first connecting section 51 is bent and smoothly transitioned to the incoming line terminal 3, and the lower end of the first connecting section 51 is smoothly transitioned to the upper end of the arc-shaped connecting section 53. The second connecting section 52 is arranged obliquely downward, the upper end of the second connecting section 52 is smoothly transitioned to the lower end of the arc-shaped connecting section 53, and the lower end of the second connecting section 52 is bent and smoothly transitioned to the outgoing line terminal 4.

[0031] By means of the coordinated connection of the first connecting section 51 , the second connecting section 52 and the arc-shaped connecting section 53 , the entire instrument wire harness protection box can extend obliquely downward from the incoming wire terminal 3 , thereby changing the wiring direction of the wire harness.

[0032] In a preferred embodiment, see Figure 1As shown, with the bottom wall 1 as a reference, the height of the upper side wall at the first connecting section 41 is greater than the height of the lower side wall, so that the wiring harness turns and runs diagonally downward above the crossbeam assembly 12. Here, the box body and the instrument panel crossbeam assembly cooperate to surround the wiring harness on all sides to better fix and protect the wiring harness.

[0033] In a preferred embodiment, see Figure 1 As shown, a plurality of fixing plates 6 fixedly connected to the crossbeam assembly 12 are connected to the bottom wall 1 and / or the side wall 2 .

[0034] For example, see Figure 4 As shown, there are three fixing plates 6 , which are distributed at the upper, middle and lower positions of the instrument wire harness protection box, to ensure that the instrument wire harness protection box can be stably assembled on the crossbeam assembly 12 .

[0035] In this embodiment, threaded holes 61 are provided on the fixing plate 6 to facilitate better connection and fixation with the crossbeam assembly 12 .

[0036] In a preferred embodiment, see Figure 1 As shown, the bottom wall 1 is provided with a first tie hole 7 at a position corresponding to the inlet terminal 3, and the bottom wall 1 is provided with a second tie hole 8 at a position corresponding to the outlet terminal 4. The first tie hole 7 and the second tie hole 8 are both arranged at the connection position between the bottom wall 1 and the side wall 2.

[0037] In some embodiments, the bottom wall 1 and / or the side wall 2 are provided with a plurality of through holes or notches used as lead branches 10. Exemplarily, the number of the lead branches 10 is three. Figure 1 As shown, one of the lead branches 10 is arranged on the lower side wall 2 near the incoming line terminal 3, and the other two lead branches 10 are arranged on the upper and lower side walls 2 near the incoming line terminal 3, respectively.

[0038] By arranging the lead branch 10 on the bottom wall 1 and / or the side wall 2, different vehicle configurations can be selected to realize the platformization of the wire protection box.

[0039] Preferably, the bottom wall 1 is provided with a third tie hole 9 at a position corresponding to the through hole or the notch, for installing a tie for fixing the wire harness. The wire harness is fixed to the bottom wall 1 by the tie, ensuring that the wire harness fits tightly to the bottom wall, ensuring that the direction of the wire harness is consistent with the direction of the wire harness channel, and avoiding the risk of the wire harness being separated from the wire harness channel.

[0040] The inlet terminal 3, the outlet terminal 4 and the outlet of the lead branch 10 are all chamfered to prevent the wire harness from being damaged by the box body.

[0041] In some embodiments, in order to enhance the overall structural strength of the instrument harness protection box, a plurality of reinforcing ribs 11 are provided on the side of the bottom wall 1 and / or the side wall 2 facing away from the harness channel. And because the reinforcing ribs 11 are arranged on the side of the bottom wall 1 and / or the side wall 2 facing away from the harness channel, damage to the harness is avoided.

[0042] It should be noted that the shape, size and distribution of the reinforcing ribs 11 are reasonably designed according to actual performance requirements.

[0043] In one embodiment, the utility model provides an instrument panel assembly, including a crossbeam assembly and the above-mentioned instrument wire harness protection box installed on the crossbeam assembly.

[0044] In one embodiment, the utility model provides a vehicle, comprising the above-mentioned instrument panel assembly.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
