[0042] It is to be understood that the embodiments described herein are merely illustrative of the principles of the present application. Numerous modifications can be made to the embodiments described herein without departing from the spirit and scope of the present application.

[0044] In addition, in the following description, numerous specific details are provided in order to provide a thorough understanding of the examples. However, it will be apparent to one of ordinary skill in the art that the examples can be practiced without these specific details.

[0045] The conventional wire harness protection device is connected with the airbag fixing bracket, and the airbag fixing bracket is composed of metal parts, which has large volume, large weight and high price.

[0046] At present, with the development of new energy vehicles, the whole vehicle is reducing weight and cost, with the customers constantly requiring cost reduction and weight reduction, facing the situation of canceling the air bag fixing support, but the air bag as a safety system, if the fixing support is simply canceled, the protection device of the wire harness connector will be canceled, which undoubtedly increases the safety risk of the air bag.

[0047] Based on this, the embodiment of the present application provides a processing scheme: as Figure 1 shown, the wire harness connector protection support of the utility model, the stop portion 30 is fixed to the workpiece 10 near one end of the wire harness connector 11 through the connecting portion 20, so that the stop portion 30 can protect the wire harness connector 11, avoid extrusion of external extrusion, so that after the air bag fixing support is canceled, the wire harness connector protection support can also be used to protect the wire harness connector 11 of the gas generator.

[0048] The technical scheme provided by the embodiments of the present application is described below in conjunction with the drawings.

[0049] Embodiment 1

[0050] As Figures 1 to 5 shown, the embodiment provides a wire harness connector protection support applied to a workpiece 10 with a wire harness connector 11, comprising a connecting portion 20 and a stop portion 30. Wherein, the connecting portion 20 is installed on one end of the workpiece 10 near the wire harness connector 11; one end of the stop portion 30 is connected with the connecting portion 20, and the other end extends to the direction where the wire harness connector 11 is located, and the stop portion 30 can shield the wire harness connector 11 on at least one side of the wire harness connector 11.

[0051] Wherein, the connecting portion 20 is used to install the stop portion 30 on one end of the workpiece 10 near the wire harness connector 11, so that the stop portion 30 can extend to shield at least one side of the wire harness connector 11.

[0052] Wherein, the connecting mode of the connecting portion 20 and the workpiece 10 includes but is not limited to clamping, bolt connection, bonding, interference and other connection modes.

[0053] Wherein, the workpiece 10 can be a gas generator.

[0054] Wherein, the stop portion 30 is used to protect the wire harness connector 11, to avoid extrusion of external extrusion to the wire harness connector 11.

[0055] Preferably, the stop portion 30 is in a half-enclosing structure to half-enclose the wire harness connector 11.

[0056] Wherein, the stop portion 30 has a certain hardness, which will not tilt to the direction where the wire harness connector 11 is located when extruded.

[0057] Further, as shown in Figure 2 The stopper 30 includes a profiling segment 31 connected to the connecting segment 20 to at least semi-enclose the wire harness connector 11.

[0058] The profiling segment 31 has a profile substantially the same as that of the wire harness connector 11 to profilely shield the wire harness connector 11.

[0059] For example, when the wire harness connector 11 is circular, the profiling segment 31 is an arc-shaped plate structure to semi-enclose the wire harness connector 11.

[0060] The connecting manner of the profiling segment 31 and the connecting segment 20 includes but is not limited to welding, one-piece forming, etc.

[0061] Further, the stopper 30 further includes an extension segment 32 extending from a side edge of the profiling segment 31 to the wire harness direction connected to the wire harness connector 11 to protect the partial wire harness connected to the wire harness connector 11.

[0062] The extension segment 32 is used to shield the partial wire harness connected to the wire harness connector 11 to avoid the partial wire harness being extruded by external extrusion objects, causing the wire harness connector 11 to be disconnected from the workpiece 10 / gas generator.

[0063] The extension segment 32 can be a flat plate structure or an arc-shaped structure to protect the wire harness.

[0064] Preferably, the extension segment 32 is a flat plate structure to reduce the manufacturing difficulty of the extension segment 32.

[0065] In some embodiments, the stopper 30 is two and oppositely arranged to shield the wire harness connector 11 on at least two opposite surfaces.

[0066] Preferably, the profiling segments 31 of the two stoppers 30 completely shield the wire harness connector 11 in width and length to avoid external extrusion objects extruding the wire harness connector 11.

[0067] For example, when the stopper 30 protects the wire harness connector 11 on the gas generator, the profiling segments 31 of the stopper 30 are arc-shaped plate structures oppositely arranged and located on both sides of the wire harness connector 11 to protect the wire harness connector 11 on at least two surfaces.

[0068] Further, as shown in Figures 3 to 5 The connecting segment 20 is a ring structure with a notch, the connecting segment 20 is clamped on the workpiece 10 in interference, and the connecting segment 20 can be sleeved on workpieces 10 of different sizes through the notch.

[0069] Preferably, the connecting part 20 is an elastic non-metal part, and the connecting part 20 is elastically clamped on the workpiece 10, so as to reduce the weight of the wire harness connector protection bracket.

[0070] The connecting part 20 can expand outward from the gap to adapt to workpieces 10 of different sizes, and can clamp the workpiece 10 under the action of its own elasticity, so that the connecting part 20 and the workpiece 10 are tightly connected or interference connected.

[0071] The connecting part 20 can be an elastic plastic part to reduce the weight of the wire harness connector protection bracket, and the plastic part is easy to deform, has sufficient elasticity, and is convenient for the connecting part 20 to be clamped on the workpiece 10.

[0072] For example, when the connecting part 20 is clamped on the gas generator, the connecting part 20 has a gap structure and is a plastic part, and at this time the two arms of the connecting part 20 can be clamped on the gas generator to shield and protect the wire harness connector 11.

[0073] The inner diameter of the connecting part 20 can be 16.5mm, and the inner diameter of the connecting part 20 is smaller than the outer diameter of the workpiece 10, so that the connecting part 20 can be interference clamped on the workpiece 10.

[0074] Further, the inner wall of the connecting part 20 is connected to the workpiece 10 through the limiting protrusion and the limiting groove, so as to limit the rotation of the connecting part 20 along the circumference of the workpiece 10.

[0075] The limiting groove and the limiting protrusion can be multiple.

[0076] For example, in the case where the workpiece 10 is provided with a limiting groove, the inner wall of the connecting part 20 is provided with a limiting protrusion, and after the connecting part 20 is clamped on the workpiece 10, the limiting protrusion enters the corresponding limiting groove, so as to limit the position of the workpiece 10, and avoid the rotation of the connecting part 20 along the circumference of the workpiece 10.

[0077] In some embodiments, the connecting part 20 can also be interference connected with the workpiece 10 through the limiting protrusion and the limiting groove.

[0078] In some embodiments, as shown in Figure 2 The wire harness connector protection bracket further includes a mounting part 40, one end of the mounting part 40 is connected with the connecting part 20, and the other end of the mounting part 40 is sleeved on the bolt 12 on the workpiece 10, so as to install and fix the wire harness connector protection bracket between the workpiece 10 and the mounting position.

[0079] Specifically, when the workpiece 10 is installed in the installation position, the mounting part 40 of the wire harness connector protection bracket is clamped between the workpiece 10 and the installation position to fix the wire harness connector protection bracket between the workpiece 10 and the installation position, so as to prevent the wire harness connector protection bracket from shifting or detaching from the workpiece 10.

[0080] Furthermore, such as Figures 3 to 5 As shown, the mounting part 40 includes a transition section 41 and a connecting section 42. One end of the transition section 41 is connected to the connecting part 20, and the shape of the transition section 41 facing the workpiece 10 matches the non-straight section of the workpiece 10. The connecting section 42 is arranged along the straight section of the workpiece 10, and one end of it is connected to the transition section 41, while the other end is fitted onto the bolt 12 on the workpiece 10 through a through hole.

[0081] The transition section 41 is used to transition the non-straight section of the workpiece 10 so that the connecting section 42 and the connecting part 20 can be connected through the transition section 41.

[0082] For example, when the workpiece 10 is a gas generator and the connecting part 20 is clamped in the area with a smaller diameter of the gas generator, the transition section 41 blocks the area with a smaller diameter and the area with a larger diameter of the gas generator to serve as a transition.

[0083] The connecting section 42 is used to fit onto the bolt 12 on the workpiece 10 to fix the wire harness connector protection bracket between the workpiece 10 and the installation position.

[0084] For example, when the gas generator is connected to the seat frame via bolt 12, one end of the connecting section 42 is fitted onto bolt 12 through a through hole. After the gas generator is connected to the seat frame via bolt 12, the connecting section 42 is clamped between the gas generator and the seat frame to fix the wiring harness connector protection bracket.

[0085] The working principle of this embodiment is explained below using workpiece 10 as an example of a gas generator:

[0086] The connecting part 20 is clamped at the tail of the gas generator, such that the contoured section 31 at least covers and protects at least one side of the wire harness connector 11, and the extension section 32 can cover and protect the portion of the wire harness connected to the wire harness connector 11.

[0087] The transition section 41 is attached to the transition area between the tail end and the middle section of the gas generator. After the connecting section 42 is attached to the middle section of the gas generator, it is fitted onto the bolt 12 of the gas generator. Finally, the gas generator is installed to the seat frame through the bolt 12.

[0088] The wire harness connector protection bracket of the embodiment can protect the wire harness connector 11 after the air bag fixing bracket is removed, avoid the wire harness connector 11 from being extruded by external extrusion objects, and is more convenient and economical than the existing air bag fixing bracket.

[0090] The embodiment provides a gas generator, which comprises a gas generator body and the wire harness connector protection bracket as described in embodiment 1; the tail end of the gas generator body is connected with the wire harness connector 11; the connecting part 20 of the wire harness connector protection bracket is connected to the tail end of the gas generator body, and the stop part 30 of the wire harness connector protection bracket at least shields one side of the wire harness connector 11.

[0091] The gas generator is connected to the seat frame through the bolt 12 on the gas generator body.

[0092] The connecting part 20 is a circular structure with a notch and is made of elastic plastic, so as to be clamped on the tail end of the gas generator with interference and reduce the weight of the connecting part 20.

[0093] The notch makes the connecting part 20 have an overall arc structure, so that the connecting part 20 can be opened outward to adapt to gas generators with different diameters.

[0094] Preferably, the wire harness connector protection bracket is made of plastic as a whole, so as to reduce the weight and provide shielding protection for the wire harness connector 11.

[0095] Further, the diameter of the tail end of the gas generator body is smaller than the diameter of the middle section of the gas generator body, the transition section 41 of the wire harness connector protection bracket is located at the connection between the tail end and the middle section, and the other end of the connecting section 42 of the wire harness connector protection bracket is threaded through the bolt 12 on the gas generator body.

Especially, for the product embodiment described later, since it corresponds to the method, the description is relatively simple, and the related parts can be referred to the part of the system embodiment.
