[0039] Embodiment 1

[0040] like Figure 1 and Figure 2 As shown, the present embodiment provides an air curtain 4 bracket 1, including a positioning plate 12 and a bearing plate 11, the bottom of the bearing plate 11 being arranged horizontally and tilted upward is connected to the top of the positioning plate 12, the side of the positioning plate 12 located below the bearing plate 11 is the inner side, and the side opposite to the inner side is the outer side, the inner side of the positioning plate 12 is provided with at least two harness clamps 2, and the outer side of the positioning plate 12 is provided with at least two connecting parts 3. Specifically, in the present embodiment, the number of harness clamps 2 and connecting parts 3 are both two. In other embodiments, the settings are made according to actual needs, and this application does not impose any restrictions. It should be noted that in the present embodiment, the positioning plate 12 and the bearing plate 11 are an integrally formed structure.

[0041] During actual use, the positioning plate 12 is connected to the vehicle body through the connecting part 3, and the supporting plate 11 is used to support the air curtain 4. Since the supporting plate 11 is inclined, the supporting area formed between the supporting plate 11 and the vehicle body has an anti-slip limiting function, ensuring that the air curtain 4 can be stably located on the supporting plate 11; the wiring harness 41 carried on the air curtain 4, and the wiring harness 41 passing through the air curtain bracket are all clamped in the wiring harness clamp 2, and are clamped in the wiring harness clamp 2, making full use of the space between the bracket 1 and the vehicle body, without using the space in other areas of the vehicle body for routing the wiring harness 41, and effectively utilizing the vehicle body space.

[0042] like Figure 1 As shown, in a specific example provided by this embodiment, the wire harness clamp 2 includes an upper clamp arm 21 and a lower clamp arm 22, one end of the upper clamp arm 21 and the lower clamp arm 22 are fixed to the inner side of the positioning plate 12, and one end of the upper clamp arm 21 and / or the lower clamp arm 22 away from the positioning plate 12 is provided with a limiting protrusion 23 to shield the area between the upper clamp arm 21 and the lower clamp arm 22. In this embodiment, the upper clamp arm 21 and the lower clamp arm 22 are both provided with a limiting protrusion 23 at one end away from the positioning plate 12, and the limiting protrusions 23 on the upper clamp arm 21 and the lower clamp arm 22 are arranged opposite to each other. Specifically, the side opposite to the limiting protrusion 23 is a curved surface structure 231, which is convenient for placing the wire harness 41. It should be noted that in this embodiment, the upper clamping arm 21 and the lower clamping arm 22 are both made of elastic materials, ensuring that the upper clamping arm 21 is bent and deformed with the end close to the positioning plate 12 as the center and away from the lower clamping arm 22. Similarly, the lower clamping arm 22 is bent and deformed with the end close to the entry positioning plate 12 as the center and away from the upper clamping arm 21.

[0043] During actual use, the wire harness 41 is pushed to squeeze the area between the two limiting protrusions 23, so that the upper clamping arm 21 and the lower clamping arm 22 are bent in relatively distant directions, which facilitates the wire harness 41 to enter the clamping area 241 between the upper clamping arm 21 and the lower clamping arm 22, and completes the installation of the wire harness 41. The wire harness 41 can be pulled in the wire harness clamp 2, which facilitates the subsequent installation of electronic components connected to the wire harness.

[0044] like Figure 1 and Figure 2 As shown, in a specific example provided by this embodiment, the connection portion 3 includes a recessed groove 31 extending from the inner side of the positioning plate 12 to the outer side of the positioning plate 12, and a first connection hole 311 is provided at the bottom of the recessed groove 31. In actual use, the bolt passes through the first connection hole 311 and is fixedly connected to the vehicle body. The recessed groove 31 can prevent the bolt from having a portion protruding from the inner side of the positioning plate 12, and avoid friction between the wiring harness 41 and the bolt during the driving of the vehicle, thereby ensuring a stable electrical connection between the wiring harness 41 and the air curtain 4, and further ensuring that the air curtain 4 can be in a normal state for a long time.

[0045] like Figure 2As shown, in a specific example provided by this embodiment, the connection portion 3 further includes a positioning column 32, and the positioning column 32 is located on the outer side of the positioning plate 12. During the installation of the positioning plate 12 and the vehicle body, the positioning column 32 is first inserted into the corresponding position of the vehicle body to ensure that the first connection hole 311 corresponds to the connection point of the vehicle body. The accurate installation of the positioning plate 12 is ensured. At the same time, the installation efficiency between the bracket 1 and the vehicle body is improved.

[0046] The positioning post 32 facilitates the fixed connection between the positioning plate 12 and the vehicle body. The positioning post 32 cooperates with the vehicle body, and then facilitates the first connection hole 311 to be connected to the corresponding connection point on the vehicle body. However, the operator still needs to support the positioning plate 12 to prevent the positioning post 32 from sliding off the vehicle body. Figure 3 As shown, in a specific example provided by this embodiment, the positioning column 32 is a hollow structure, an elastic sheet 321 is provided on the positioning column 32, and a limit block 33 is provided on the elastic sheet 321. Specifically, a U-shaped hole 322 is provided on the side surface of the positioning column 32, so that an elastic sheet 321 is formed on the positioning column 32 surrounded by the opening of the U-shaped hole 322, and the elastic sheet 321 can be bent and deformed toward the center of the positioning column 32 when subjected to an external force. The provision of the elastic sheet 321 in this embodiment does not increase the radial size of the positioning column 32 itself. It is still necessary to explain that the limit block 33 is located at the outer periphery of the elastic sheet 321, and has a certain bearing portion between the limit block 33 and the free end of the elastic sheet 321, and the limit block 33 has an installation bevel 331, and the end of the installation bevel 331 away from the elastic sheet 321 has an arc-shaped transition surface 332.

[0047] During the installation process, when the positioning column 32 passes through the vehicle body, the limit block 33 is squeezed, and the elastic sheet 321 is deformed toward the center of the positioning column 32. The installation inclined surface 331 facilitates the continued advancement of the limit column until the limit block 33 completely penetrates the vehicle body and returns to the initial state under the elastic effect of the elastic sheet 321 itself. The bearing part is located on the vehicle body, and the limit block 33 defines the relative position between the positioning plate 12 and the vehicle body to prevent the positioning column 32 from sliding out of the vehicle body, wherein the arc-shaped transition surface 332 facilitates the elastic sheet 321 to return to the initial state. Since the limit block 33 in this embodiment can prevent the positioning column 32 from sliding out of the vehicle body, the bracket 1 does not need to be lifted during the installation process, further improving the installation efficiency.

[0048] like Figure 1As shown, in a specific example provided by this embodiment, the air curtain 4 bracket 1 of the present application also includes a connecting plate 13, the top of the connecting plate 13 is connected to the bottom of the positioning plate 12, and the connecting plate 13 is provided with a positioning hole 131. It should be noted that in this embodiment, the connecting plate 13 and the positioning plate 12 are an integrally formed structure, which is used to ensure the stability of the bracket 1. The connecting plate 13 is fixed to the vehicle body through the positioning hole 131, and the positioning plate 12 is fixed to the vehicle body through the connecting portion 3. The double fixation between the positioning plate 12 and the connecting plate 13 and the vehicle body is used to ensure a stable connection between the bracket 1 and the vehicle body. It should be noted that in other embodiments, a stabilizing member is provided on the positioning plate 12, and the stabilizing member is connected to the vehicle body to ensure the stability of the connection between the bracket 1 and the vehicle body. Therefore, the present application does not limit the specific structure for adding a stable connection between the bracket 1 and the vehicle body.

[0049] like Figure 1 As shown, in a specific example provided by this embodiment, a plurality of reinforcing ribs 14 are provided on the positioning plate 12, and the reinforcing ribs 14 include an upper reinforcing rib 141 extending to the bearing plate 11, and a lower reinforcing rib 142 extending to the connecting plate 13. The reinforcing ribs 14 in this embodiment further improve the stable connection between the bearing plate 11, the positioning plate 12 and the connecting plate 13, and at the same time, ensure that the bearing plate 11 can stably carry the air curtain 4, further ensuring the subsequent normal use of the air curtain 4.

[0050] Embodiment 2

[0051] like Figure 4 and Figure 5 As shown, this embodiment provides a C-pillar air curtain assembly, including the air curtain 4 bracket 1 in the first embodiment, and also includes the air curtain 4, the wiring harness 41 and the side panel 5; the air curtain 4 is fixed to the side panel 5 through a connecting piece; the wiring harness 41 is placed in the wiring harness clamp 2; the side panel 5 is provided with a second connecting hole 51 for the bolt to pass through and connect to the connecting part 3.

[0052] like Figure 4 and Figure 5 As shown, in a specific example provided by this embodiment, the connecting member includes a connecting seat 42 fixed on the air curtain 4 and a connecting piece 43 installed on the connecting seat 42, and at least one hook 431 is provided on the connecting piece 43; and a strip hole 52 is provided on the side panel metal 5 to match each hook 431. In actual use, the hook 431 passes through the strip hole 52, and the hook body of the hook 431 hooks the side panel metal 5 by relying on the gravity of the air curtain 4 itself, so as to prevent the air curtain 4 from sliding off.

[0053] It should be noted that this embodiment illustrates a specific connection structure between the air curtain 4 and the side panel 5. In other embodiments, the connecting parts on the air curtain 4 are fixedly connected to the vehicle body by bolts, which is not limited here. The specific structures that can ensure the connection between the air curtain 4 and the vehicle body are all within the protection scope of this application.

[0054] Specifically, firstly, the wiring harness 41 is buckled into the wiring harness clamp 2, the positioning column 32 on the positioning plate 12 passes through the opening on the side panel 5, the bearing portion on the elastic sheet 321 abuts against the side panel 5 where the opening is located, the limit block 33 limits the relative sliding between the positioning plate 12 and the side panel 5, and then the bolt passes through the first connection hole 311 and the second connection hole 51 on the side panel 5 to connect the positioning plate 12 and the side panel 5 together; finally, the air curtain 4 and the side panel 5 are installed in the above-mentioned installation method to connect the air curtain 4 to the side panel 5, so that the air curtain 4 is located above the bearing plate 11, and the installation of the C-pillar air curtain assembly is completed. The C-pillar air curtain assembly provided in this embodiment can make full use of the space of the bracket 1 while improving the installation efficiency of the C-pillar air curtain assembly.
