[0035] Embodiment

[0036] In the field of automotive component wire harnesses, the firewall rubber part of the wire harness component refers to an elastic rubber part used to ensure good sealing performance, reliability, etc. during the process of the wire harness passing through the automotive firewall. Currently, when the firewall rubber part is used for the main trunk with a relatively large wire diameter (greater than 30 mm), an injection molding bracket is commonly used as a fixed support.

[0037] Because the wire harness passing through the firewall is generally thick and stiff and not easy to bend. The wire harness in this part driving the rubber part easily causes poor sealing and water leakage. At the same time, when the wire diameter of the wire harness exceeds a certain size, it is very difficult to bend the wire harness. The rubber part designed with a general structure is easily separated from the sheet metal under the driving force of the wire harness bending stress, and it is difficult to meet the assembly sealing requirements with the sheet metal and the directional bending requirements of the wire harness.

[0038] When the wire harness is designed with a directional routing layout, there are specific requirements for the rotation angle of the rubber part. The conventional solution is to use an oblong hole rubber part bracket. Since the actual production tooling of the wire harness is a planar structure, it is difficult to ensure the consistency of the 3D layout state of the main trunk of the wire harness after actual vehicle installation, resulting in interference between the wire harness and surrounding components such as the pipes of the thermal management system.

[0039] In view of this, as Figure 1 - Figure 2 shown, on the one hand, the embodiment of the present application provides a rubber part, including: a rubber body 100, which is configured with an outlet hole 101 for the wire harness to lead out from the inner cavity of the rubber body 100 after passing through the bending of the rubber body 100; a guiding and protecting shell 200, which is adapted to the outside of the rubber body 100, and the guiding and protecting shell 200 is configured with a fixing part 203 at the position of the outlet hole 101, and the fixing part 203 is configured to fix the wire harness.

[0040] Exemplarily, the guiding and protecting shell 200 is connected to the rubber body 100, and when the guiding and protecting shell 200 cooperates with the rubber body 100, the inner cavity of the guiding and protecting shell 200 can be attached to the outer wall of the rubber body 100, that is, the shape of the fitting part 204 of the rubber body 100 and the guiding and protecting shell 200 is set to be the same as the shape of the guiding and protecting shell 200.

[0041] The fixing part 203 includes but is not limited to a protrusion, and the protruding direction of the fixing part 203 includes but is not limited to the direction in which the guiding and protecting shell deviates from the rubber body, so that the wire harness at the outlet hole 101 can be bundled on the fixing part 203 through a cable tie.

[0042] In the above implementation process, the guiding protective shell 200 is adapted to the rubber body 100. The rubber body 100 can bend the wire harness. And when the wire harness passes through the rubber body 100 and is led out from the wire outlet hole 101, the wire harness can be fixed by the fixing part 203 on the guiding protective shell 200, effectively achieving the functions of reliable fixing of the wire harness and directional arrangement of the wire harness, improving the reliability and consistency of the product, and solving the problem that ordinary rubber products cannot be directionally bent and arranged due to the thick and hard wire harness.

[0043] As Figure 1 shown, the guiding protective shell 200 includes a protective shell body 201 and a guiding body 202. The guiding body 202 is connected to the protective shell body 201. The distribution of the guiding body 202 is consistent with the distribution of the wire outlet holes 101, and the fixing part 203 is arranged on the side of the guiding body 202 facing away from the fixing part 203.

[0044] Exemplarily, the protective shell body 201 and the guiding body 202 can be formed into an integral structure by an integral molding technique. A part of the structure of the protective shell body 201 can be configured as a cone, and the guiding body 202 can be configured as a semi-cylindrical shape, which can be used to fit with the rubber body. And the materials of the protective shell body 201 and the guiding body 202 can be metal materials or plastic materials, etc.

[0045] In the above implementation process, the protective shell body 201 and the guiding body 202 are connected as a whole, which can ensure the structural strength after the guiding shell is connected to the rubber body 100, solve the problem that ordinary rubber products cannot be directionally bent and arranged due to the thick and hard wire harness, and improve the reliability and consistency of the product.

[0046] As Figure 1 shown, the rubber part further includes a support part 300. The support part 300 includes but is not limited to a support frame. The material of the support part 300 includes but is not limited to iron materials, etc. And the support part 300 can be configured as a plate shape. The support part 300 is arranged between the rubber body 100 and the guiding protective shell 200 and can be respectively attached to the rubber body 100 and the guiding protective shell 200.

[0047] In the above implementation process, the support part 300 is used to connect between the rubber body 100 and the guiding protective shell 200, which can effectively play a supporting role, solve the situation that ordinary rubber products are separated from the sheet metal due to excessive stress caused by the thick and hard wire harness, and improve the feasibility of layout in the narrow space of the vehicle body.

[0048] In some embodiments, a connecting part 301 is arranged on the side of the support part 300 close to the guiding protective shell 200, and the guiding protective shell 200 is provided with an adapting part 204, and the adapting part 204 is configured to be adapted to the connecting part 301.

[0049] Exemplarily, the connecting portion 301 extends along the direction in which the support member 300 approaches the guiding protective shell 200, and the connecting portion 301 and the support member 300 can be integrally formed by welding or integrally molding.

[0050] In the above implementation process, the adaptation portion 204 is adapted to the connecting portion 301, which can fix the support member 300 and the guiding protective shell 200, avoid the wire harness driving the rubber body 100 to separate from the sheet metal, resulting in the phenomenon of water leakage due to poor sealing, and also avoid the problem of the wire harness guiding being unable to be fixed in a specific direction.

[0051] In some embodiments, at least two connecting portions 301 are provided. For example, two connecting portions 301 are provided, and the two connecting portions 301 are spaced apart on opposite sides of the support member 300. The connecting portion 301 includes a clamping member, and the adaptation portion 204 includes a clamping groove. For example, the clamping member includes but is not limited to a buckle. Of course, in other embodiments, the connecting portion 301 can also be a clamping groove, and the adaptation portion 204 can be a clamping member adapted to the clamping groove, etc.

[0052] In the above implementation process, a plurality of clamping members are provided on the support member 300, and clamping grooves are provided on the guiding protective shell 200, which can ensure the stability of the connection between the support member 300 and the guiding protective shell 200. At the same time, under the adaptation of the plurality of clamping members and the clamping grooves, the guiding protective shell 200 can be prevented from rotating, improving the feasibility of layout in the narrow space of the vehicle body.

[0053] Please refer to Figure 1 , the support member 300 is provided with an avoidance groove 302, and the avoidance groove 302 is configured to allow a part of the structure of the rubber body 100 to pass through, and this part of the structure extends into the inner cavity of the guiding protective shell 200.

[0054] Exemplarily, the avoidance groove 302 is located at the central position of the support member 300. The shape of the avoidance groove 302 includes but is not limited to a circle, and the diameter of the avoidance groove 302 can be set according to the outer edge size of the rubber body 100.

[0055] In the above implementation process, the support member 300 is sleeved on the rubber body 100 through the avoidance groove 302, which can play a supporting role, and the part of the rubber body 100 passing through the avoidance groove 302 extends into the inner cavity of the guiding protective shell 200, solving the situation that ordinary rubber products are separated from the sheet metal due to excessive stress caused by the thick and hard wire harness, and improving the feasibility of layout in the narrow space of the vehicle body.

[0056] In some embodiments, the rubber body 100 further includes an inlet hole 102, which is in communication with the outlet hole 101, and the inlet hole 102 and the outlet hole 101 are distributed at a preset angle. For example, the preset angle between the inlet hole 102 and the outlet hole 101 is greater than 90°, etc. Of course, the case where the preset angle is set to be less than 90° is not excluded.

[0057] In some embodiments, the rubber body 100 further includes a cone 103, which is disposed in the inner cavity of the guiding and protecting shell 200, and the outlet hole 101 is disposed on the outer side of the cone 103.

[0058] In some embodiments, the rubber body 100 is provided with a fixing hole 104, which is used to fix the rubber body 100, the support member 300 and the guiding and protecting shell 200. Correspondingly, the support member 300 and the guiding and protecting shell 200 are both provided with fitting holes adapted to the fixing hole 104 to fix the three of them.

[0059] In the above implementation process, the rubber body 100, the support member 300 and the guiding and protecting shell 200 are fixed through the fixing hole 104, which can prevent the wire harness from driving the rubber body 100 to separate from the sheet metal, resulting in poor sealing and water leakage. At the same time, it can also prevent the problem of the wire harness guiding being unable to be fixed directionally.

[0060] In a second aspect, the present application further provides a vehicle, including the rubber part as described above.

[0061] During the assembly process of the rubber part, bolts must be used and fixed in cooperation with the body opening. Since the fixing structure of this rubber part is different from the conventional plastic direct barb clamping structure, bolts need to be added to limit and fix through the bracket holes to ensure the stability of the assembly structure.

[0062] At the same time, the rubber part can be horizontally extended to other situations where there are similar perforation and guiding arrangement requirements but the conventional rubber parts cannot meet the guiding requirements, such as the situation where the front and rear door wire harnesses are arranged in an environment where the internal space of the body sheet metal is relatively narrow due to styling restrictions.

[0063] The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.

[0064] Since the vehicle provided in the second aspect includes the rubber part, the vehicle has all the technical effects of the rubber part, which will not be elaborated here.

[0065] In all embodiments of the present application, "large" and "small" are relative, "many" and "few" are relative, and "upper" and "lower" are relative. For the expression of such relative terms, the embodiments of the present application will not elaborate further.
