DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] In the description of the present application, it should be understood that the terms "thickness", "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0034] The applicant noted that in the field of electric vehicles, a clamp structure is usually required to fix the charging busbar to the vehicle body. The clamp structure is usually composed of a rubber sheath, a metal bracket and a cable tie. The busbar is fixed to the rubber sheath and the metal bracket by a cable tie. When the busbar is installed on the vehicle body, the clamp structure cannot move up and down or left and right along the busbar to absorb the installation tolerance. At the same time, the busbar is usually a rigid body, which makes it difficult to install the busbar on the vehicle body.

[0035] In addition, for busbars of different specifications and sizes, the designs of rubber sheaths and metal brackets are also different. Therefore, it is often necessary to re-open the mold, design and manufacture for different busbars, which undoubtedly leads to an increase in parts costs.

[0036] In view of this, combined with Figures 1 to 4 , an embodiment of the present application provides a busbar fixing device, aiming to overcome at least one of the above-mentioned technical problems.

[0037] Reference Figures 1 to 4 The busbar fixing device includes a shell 1, a cover 2 and an elastic insulating component 3. The shell 1 has a busbar channel 10 that penetrates the shell 1 in a first direction X and an opening 11 that communicates with the busbar channel 10 in a second direction Y. The cover 2 is detachably connected to the shell 1 and covers the opening 11. The elastic insulating component 3 is at least partially connected to the shell 1 and is located in the busbar channel 10. The elastic insulating component 3 is configured to be able to elastically abut the busbar in the second direction Y and the third direction Z.

[0038] It should be noted that the first direction X, the second direction Y and the third direction Z intersect each other. Figure 1 In this embodiment, the busbar body 6 is introduced as a reference. The first direction X is parallel to the extension direction of the busbar body 6, the second direction Y is parallel to the width direction of the busbar body 6, and the third direction Z is parallel to the thickness direction of the busbar body 6.

[0039] The elastic insulating component 3 elastically abuts against the busbar body 6 to form a fixing effect on the busbar body 6. At the same time, relying on the deformation ability of the elastic insulating component 3, the versatility of the busbar channel 10 for busbar bodies 6 of various specifications and sizes can be improved. During the assembly of the busbar body 6, the busbar fixing position can be flexibly adjusted, thereby improving the convenience of installation and adjustment of the busbar body 6.

[0040] Specifically, refer to Figure 1 and Figure 2 In some embodiments, the shell 1 includes a first part 12, a second part 13 and a third part 14 connecting the first part 12 and the second part 13 arranged in a third direction Z, and the first part 12, the second part 13 and the third part 14 surround the busbar channel 10.

[0041] Corresponding, refer to Figure 1 and Figure 2 The cover body 2 includes a cover portion 21 facing the opening 11, a connecting portion 22 provided at one end of the cover portion 21 in the third direction Z, and a hinge shaft 23 provided at the other end of the cover portion 21 in the third direction Z. When the cover body 2 and the housing 1 are connected, the connecting portion 22 abuts against the first portion 12, and the hinge shaft 23 is located on the side of the second portion 13 away from the first portion 12.

[0042] In order to realize the detachable connection between the housing 1 and the cover 2, refer to Figure 2 and Figure 3 , the connecting portion 22 is provided with a card slot 220, and the first portion 12 is provided with a first card portion 15 for engaging the card slot 220. The second portion 13 is provided with a hook 16 for embedding the hinge shaft 23 on the side away from the first portion 12. It can be understood that, on this basis, when the opening 11 needs to be opened to import or export the busbar body 6 to the busbar channel 10, the hinge shaft 23 may not be separated from the hook 16, and the cover body 2 only needs to be rotated around the hinge shaft 23 to separate the first card portion 15 and the connecting portion 22, so as to facilitate closing the opening 11 again. In other embodiments, the hinge shaft 23 may not be used and may be replaced by a structure such as the connecting portion 22, and the corresponding first portion 12 and the second portion 13 are both provided with a structure such as the first card portion 15 to achieve a matching detachable card connection.

[0043] In addition, the busbar fixing device in this embodiment further includes a separator 4, which is connected to the housing 1 and is located in the busbar channel 10. The separator 4 divides the busbar channel 10 and forms a plurality of sub-channels 101. The separator 4 extends in the second direction Y, one end of the separator 4 is connected to the third portion 14, and the other end faces the opening 11, so as to form two sub-channels 101 spaced apart from each other in the third direction Z. In this embodiment, refer to Figure 1 , taking the example that each sub-channel 101 can be penetrated by a busbar body 6 .

[0044] Reference Figures 1 to 4 In this embodiment, the elastic insulating component 3 includes a first elastic insulating member 30, a second elastic insulating member 31, a third elastic insulating member 32 and a fourth elastic insulating member 33. The first elastic insulating member 30, the second elastic insulating member 31, the third elastic insulating member 32 and the fourth elastic insulating member 33 are provided in plurality.

[0045] It should be noted that in this embodiment, the housing 1, the partition 4, and the first elastic insulating member 30, the second elastic insulating member 31, and the fourth elastic insulating member 33 can be integrally formed and manufactured, and the housing 1, the cover 2, and the elastic insulating assembly 3 can be made of elastic and insulating materials such as insulating rubber, which will not be repeated here. The first elastic insulating member 30, the second elastic insulating member 31, and the fourth elastic insulating member 33 are configured as elastic tooth structures, and the corresponding busbar body 6 is abutted by the bending and elastic deformation of the elastic tooth.

[0046] In order to ensure a relatively uniform and stable elastic contact and fixation of the busbar body 6, refer to Figure 1 and Figure 2 The first portion 12 and the second portion 13 are respectively connected with a plurality of first elastic insulating members 30 . In other embodiments, only the first portion 12 or the second portion 13 may be provided with a plurality of first elastic insulating members 30 .

[0047] Similarly, in the present embodiment, a plurality of fourth elastic insulating members 33 are provided on the side of the partition 4 facing the two sub-channels 101. In order to ensure a better elastic support and fixing effect, at least one of the partition 4 and the first part 12 is provided with a corresponding first elastic insulating member 30 and a corresponding fourth elastic insulating member 33, and at least one of the partition 4 and the second part 13 is provided with a corresponding first elastic insulating member 30 and a corresponding fourth elastic insulating member 33.

[0048] Further explanation is that, refer to Figures 1 to 4In this embodiment, two second elastic insulating members 31 are provided corresponding to two sub-channels 101, and the second elastic insulating member 31 is located on the side of the sub-channel 101 away from the opening 11. In this embodiment, the second elastic insulating member 31 located between the first portion 12 and the partition 4 is connected to the first portion 12, and the second elastic insulating member 31 located between the second portion 13 and the partition 4 is connected to the second portion 13. The second elastic insulating member 31 extends and blocks between the opening 11 and the third portion 14, so as to be able to elastically abut the busbar body 6 in the second direction Y, that is, when the busbar body 6 is pushed into the sub-channel 101 toward the third portion 14, the second elastic insulating member 31 can be gradually pushed toward the third portion 14.

[0049] In addition, in other embodiments, the second elastic insulating member 31 may also be connected to the third portion 14 or the partition 4 , as long as the second elastic insulating member 31 can elastically abut against the busbar body 6 relative to the opening 11 .

[0050] In some embodiments, reference Figure 3 and Figure 4 In this embodiment, two third elastic insulating members 32 are provided corresponding to the two sub-channels 101, and the two third elastic insulating members 32 are connected to the cover 21 and face the two sub-channels 101 one by one. In this embodiment, the third elastic insulating member 32 can adopt an elastic protrusion structure protruding toward the inside of the sub-channel 101, so as to be able to elastically abut the busbar in the second direction Y, that is, when the cover body 2 is covered on the opening 11, if the busbar body 6 is correspondingly penetrated in the sub-channel 101, the third elastic insulating member 32 can push the busbar body 6 in the second direction Y and gradually deform elastically.

[0051] In order to further improve the uniformity and stability of the elastic contact between the first elastic insulating member 30 and the fourth elastic insulating member 33 and the busbar body 6, in some embodiments, referring to Figures 1 to 4 , a plurality of first elastic insulating members 30 are evenly spaced in the second direction Y, and a plurality of fourth elastic insulating members 33 are spaced in the second direction Y.

[0052] In addition, in order to facilitate the smooth introduction of the busbar body 6 into the corresponding sub-channel 101 and improve the stability of the busbar body 6 in the sub-channel 101, in some embodiments, reference Figures 1 to 4 The first elastic insulating member 30 extends toward a side away from the opening 11 , and the extending direction of the first elastic insulating member 30 intersects with the second direction Y. The fourth elastic insulating member 33 extends toward a side away from the opening 11 , and the extending direction of the fourth elastic insulating member 33 intersects with the second direction Y.

[0053] It can be understood that, through the above-mentioned design, in the process of introducing the busbar body 6 into the corresponding sub-channel 101, the first elastic insulating member 30 and the fourth elastic insulating member 33 can form a guiding slope toward the busbar body 6 to guide the busbar body 6 to be smoothly introduced, thereby reducing the obstruction to the busbar body 6; and correspondingly, when the busbar body 6 has a tendency to export the corresponding sub-channel 101 toward the opening 11, the busbar body 6 is required to generate a tendency to bend the first elastic insulating member 30 and the fourth elastic insulating member 33 toward the opening 11, that is, at this time, the first elastic insulating member 30 and the fourth elastic insulating member 33 form an obstruction to the export of the busbar body 6.

[0054] In addition, in order to improve the structural stability of the separator 4, in some embodiments, reference Figure 3 and Figure 4 The cover 21 is provided with a positioning groove 20 for the partition 4 to be embedded. That is, when the cover 21 is covered on the opening 11, the end of the partition 4 away from the third portion 14 is embedded in the positioning groove 20, and the partition 4 is positioned and supported by the positioning groove 20.

[0055] In addition, in order to facilitate the insertion of other wiring harnesses, the side of the first portion 12 away from the second portion 13 can also be equipped with Figure 1 and Figure 2 The structure of the wiring harness fixing member 7 shown can be flexibly adjusted according to needs, and will not be described in detail here.

[0056] In some embodiments, reference Figures 1 to 4 The busbar fixing device also includes a base frame 5 for connecting an external device. In this embodiment, the external device can be a vehicle body. The base frame 5 has an embedding groove 50 for the housing 1 and the cover 2 to embed, and the housing 1 and the cover 2 can be detachably connected to the base frame 5. In this embodiment, the base frame 5 is provided with four buckles 51 in the circumferential direction outside the embedding groove 50, and the four buckles 51 are opposite to each other. Correspondingly, the second part 13 is provided with a second clamping part 17 for clamping the buckle 51 on the opposite sides of the first direction X and the side of the third part 14 facing away from the opening 11, and the cover 21 is provided with a third clamping part 24 for clamping the buckle 51 on the side facing away from the opening 11.

[0057] It should be noted that the base frame 5 can be supported by plastic material, and its actual structure can be flexibly adjusted according to the needs of the connected external equipment such as the vehicle body shape structure. The structure of the above-mentioned cover body 2, shell 1 and elastic insulating component 3 does not need to be adjusted. It only needs to manufacture the adapter base frame 5 through injection molding or other methods to improve the adaptability of the installation and fixation of busbar bodies 6 of various specifications.

[0058] In addition, in order to achieve a detachable connection between the base frame 5 and the cover body 2 and the shell 1, in other embodiments, a pin shaft (not shown in the figure) can be used to connect the base frame 5 and the cover body 2 and the shell 1, or a stud thread can be used to connect the base frame 5, the cover body 2 and the shell 1 (not shown in the figure), which will not be described one by one here.

[0059] In addition, it should be noted that, referring to Figures 1 to 4 In this embodiment, the first clamping portion 15, the second clamping portion 17 and the third clamping portion 24 are all provided with inclined guide surfaces to facilitate smooth insertion into the corresponding buckle 51 or the clamping slot 220, which will not be repeated here.

[0060] Accordingly, a vehicle charging busbar in an embodiment of the present application includes the above-mentioned busbar fixing device, and also includes a busbar body 6, the busbar body 6 is inserted into the busbar channel 10, and the elastic insulating component 3 elastically abuts against the busbar body 6. It can be understood that the vehicle charging busbar can have all the technical features and corresponding beneficial effects of the above-mentioned busbar fixing device, which will not be repeated here.

[0061] The above is a detailed introduction to a busbar fixing device and a car charging busbar provided in the embodiments of the present application, and the principles and implementation methods of the present application are explained by using specific examples.
