Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0038] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as those generally understood by those of ordinary skill in the art.

[0039] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0040] The first aspect of the present application provides a door wire harness protection device, as Figure 1 shown. The door wire harness protection device includes a pipe body 1, a first connecting body 2, a second connecting body 3, a sealing portion 4, and a mounting portion 5. Among them,

[0041] The pipe body 1 connects the first connecting body 2 and the second connecting body 3.

[0042] The first connecting body 2 has a first supporting portion 21, and the first supporting portion 21 is located on the side of the first connecting body 2 opposite to the pipe body 1.

[0043] The second connecting body 3 has a first communication hole 301. The first communication hole 301 penetrates through the second connecting body 3, and the first communication hole 301 communicates with the pipe body 1.

[0044] The sealing portion 4 and the mounting portion 5 are sequentially installed on the second connecting body 3 along the extending direction of the first communication hole 301.

[0045] It can be understood that the pipe body 1 can accommodate the door wiring harness, and the first connecting body 2 and the second connecting body 3 can allow the door wiring harness located inside the pipe body 1 to pass through and connect to the electrical components and the vehicle computer. The first supporting portion 21 is located on the side of the first connecting body 2 opposite to the pipe body 1 and can form the first connecting body 2, which is beneficial to form a stable connection between the first connecting body 2 and the door and reduce the situation of the first connecting body 2 falling off. The sealing portion 4 and the mounting portion 5 are sequentially mounted on the second connecting body 3 along the extending direction of the first communication hole 301, which is beneficial to the connecting force generated by the connection between the mounting portion 5 and the vehicle body side wall panel acting on the sealing portion 4, so as to improve the sealing effect of the second connecting body 3 and reduce the situation of external impurities entering the pipe body 1 through the second connecting body 3. By taking appropriate measures at both ends of the pipe body 1, the connection performance of the door wiring harness protection device of the present application with the door and the vehicle body is maintained, thereby improving the service life.

[0046] In the embodiment of the present application, the pipe body 1 may include a corrugated section 11, which has the characteristic of being telescopic and can change its length with the opening and closing of the door. Among them, the inner diameter of the wave crest of the pipe body 1 may be 26.2 mm, and the outer diameter of the wave crest may be 29.2 mm. Since the strength of the corrugated section 11 is relatively low and it is directly connected to the first connecting body 2 and the second connecting body 3, it is easy to be torn when subjected to external force. Therefore, support sections 12 with an annular cross-sectional shape are added at both ends of the corrugated section 11, and the first connecting body 2 and the second connecting body 3 are connected through the support sections 12, which is beneficial to the normal operation and expansion and contraction of the corrugated section 11.

[0047] In the embodiment of the present application, the openings at both ends of the first communication hole 301 face different directions, which is beneficial to form a stable connection between the second connecting body 3 and the vehicle body side wall panel. Exemplarily, the openings at both ends of the first communication hole 301 form an included angle of 90°.

[0048] In the embodiment of the present application, the cross-sectional shape of the first communication hole 301 may be oval or waist-shaped.

[0049] In the embodiment of the present application, the sealing portion 4 is used to form a sealing surface at one end where the first communication hole 301 is in direct contact with the vehicle body side wall panel. The sealing surface is also beneficial to reduce the entry of external impurities into the interior of the pipe body 1 through the first communication hole 301, so as to improve its sealing performance and service life.

[0050] In the embodiment of the present application, the mounting portion 5 is located inside the first communication hole 301, which is beneficial to the formation of an assembly with the structure corresponding to the mounting portion 5 on the vehicle body side wall panel. The stability of the second connecting body 3 after assembly is improved, and in this way, the sealing portion 4 can also be squeezed. The squeezed sealing portion 4 can form a stable sealing surface, thereby improving the sealing performance of the first communication hole 301.

[0051] In the embodiment of the present application, the pipe body 1 is connected to the first connecting body 2 and the second connecting body 3. The pipe body 1 can be respectively connected to the first connecting body 2 and the second connecting body 3 by means of welding, bonding, etc.

[0052] In the embodiment of the present application, the sealing portion 4 and the mounting portion 5 are sequentially mounted on the second connecting body 3 along the extending direction of the first communication hole 301. Wherein, when the first communication hole 301 has two segments and the axes of the two segments intersect, the sealing portion 4 and the mounting portion 5 are located in the same segment.

[0053] In the embodiment of the present application, the materials of the first connecting body 2, the second connecting body 3 and the pipe body 1 may include EPDM (Ethylene Propylene Diene Monomer).

[0054] In some embodiments of the present application, as Figure 2 shown, the first support portion 21 includes a first support rib 211 and a second support rib 212. One side of the first support rib 211 and one side of the second support rib 212 are both attached to the side of the first connecting body 2 opposite to the pipe body 1, and the second support rib 212 intersects the first support rib 211.

[0055] It can be understood that when the first connecting body 2 is assembled with the vehicle door, the first support rib 211 and the second support rib 212 can resist the deformation of the first connecting body 2 to a certain extent during assembly, thereby facilitating the formation of a stable connection between the first connecting body 2 and the vehicle door, reducing the situation that the first connecting body 2 fails to be assembled in place due to deformation and falls off during use, and improving the service life.

[0056] In the embodiment of the present application, the first support rib 211 and the second support rib 212 can be formed with the first connecting body 2 by an integral molding process.

[0057] In some embodiments of the present application, as Figure 2 shown, the first connecting body 2 has a sunk groove 201. The first support rib 211 and the second support rib 212 are both attached to the bottom wall of the sunk groove 201. Two ends of the first support rib 211 are respectively connected to the side walls of the sunk groove 201, and the second support rib 212 connects the first support rib 211 and the side wall of the sunk groove 201.

[0058] It can be understood that by connecting with the side walls of the sunk groove 201, the first support rib 211 and the second support rib 212 can resist the deformation of the first connecting body 2 during assembly to maintain the shape of the first connecting body 2, which is beneficial to the formation of a stable connection between the first connecting body 2 and the vehicle door and improves the service life.

[0059] In the embodiment of the present application, the height of the first connecting body 2 is less than the depth of the sunk groove 201, so as to avoid the first connecting body 2 protruding from the sunk groove 201 and interfering with the vehicle door.

[0060] In the embodiment of the present application, the length of the first support rib 211 is greater than the length of the second support rib 212, which is beneficial for the second support rib 212 to support the first support rib 211 at the same time, so that the first support part 21 forms a relatively stable structure.

[0061] In the embodiment of the present application, the first support rib 211 and the second support rib 212 form a T shape.

[0062] In the embodiment of the present application, the cross-section of the first communication hole 301 is oval, and the cross-section of the sunk groove 201 is oval. Among them, the major axis of the cross-section of the first communication hole 301 is perpendicular to the major axis of the cross-section of the sunk groove 201, which is beneficial for the vehicle door wire harness protection device of the present application to form a constraint on the vehicle door wire harness, thereby avoiding relative displacement of the vehicle door wire harness relative to the vehicle door wire harness protection device.

[0063] In the embodiment of the present application, the plane where the opening at the end of the first communication hole 301 far from the pipe body 1 is located is perpendicular to the plane where the opening of the sunk groove 201 is located, which is beneficial for the vehicle door wire harness protection device to be connected to both the vehicle door and the vehicle body side wall panel at the same time and reduce the deformation generated by the connection.

[0064] In some embodiments of the present application, as Figure 2 shown, the number of the first support parts 21 is at least two, and two of the at least two first support parts 21 are symmetrically arranged on opposite sides of the first connecting body 2.

[0065] It can be understood that multiple first support parts 21 can support different positions of the sunk groove 201, thereby improving the stability of the first connecting body 2 to resist deformation during assembly. The first connecting body 2 with less deformation is beneficial for forming a stable connection with the vehicle door, thereby improving the service life.

[0066] In the implementation of the present application, the number of the first support parts 21 can be 2, 3 or 4, or other numbers, as long as they can be arranged in the sunk groove 201.

[0067] In some embodiments of the present application, as Figure 2 shown, the first connecting body 2 has a second communication hole 202, the second communication hole 202 penetrates the first connecting body 2 and communicates with the pipe body 1, and the extension lines of the second support ribs 212 of the two symmetrically arranged first support parts 21 pass through the axis of the second communication hole 202.

[0068] It can be understood that the second communication hole 202 can allow the door wiring harness to pass through. The extension lines of the two second support ribs 212 pass through the axis of the second communication hole 202, which is beneficial to maintaining the shape of the second communication hole 202 and reducing the extrusion of the door wiring harness at the second communication hole 202.

[0069] In the embodiment of the present application, the two symmetrically arranged first support parts 21 are in a T shape.

[0070] In some embodiments of the present application, such as Figure 1 and Figure 4 as shown, the sealing part 4 is located at one end of the first communication hole 301 and extends circumferentially along the first communication hole 301 to form a ring shape.

[0071] It can be understood that the annular sealing part 4 extends circumferentially along the first communication hole 301, which can form an annular sealing surface with the body side panel. At the same time, it is also beneficial to cooperate with the corresponding assembly structure of the installation part 5 and the body side panel to generate a connecting force perpendicular to the sealing surface, pressing the sealing part 4 on the body side panel to improve the sealing performance of the first communication hole 301 and improve the service life.

[0072] In some embodiments of the present application, such as Figure 1 and Figure 3 as shown, the outer side surface of the sealing part 4 extends obliquely from the end connected to the first communication hole 301 to the other end along the extension direction of the first communication hole 301, and a deformation space 100 is formed between the outer side surface of the sealing part 4 and the end surface of the first communication hole 301.

[0073] It can be understood that the deformation space 100 can cause the sealing part 4 to be subjected to an extrusion force along the extension direction of the first communication hole 301. In this way, it is beneficial to reduce the situation that the sealing part 4 is extruded by itself during deformation and sinks into the second communication hole 202. In this way, it is beneficial to improve the sealing effect of the sealing part 4 and improve the service life.

[0074] In some embodiments of the present application, such as Figure 1 as shown, the installation part 5 is located in the first communication hole 301, and the installation part 5 extends radially along the first communication hole 301.

[0075] It can be understood that the installation part 5 is located in the first communication hole 301, which can reduce the damage of the installation part 5 caused by the extrusion of objects outside the first communication hole 301. In this way, it is beneficial to maintain the sealing performance of the sealing part 4. The installation part 5 extends radially along the first communication hole 301, which can cooperate with the structure extending into the first communication hole 301 to form an assembly.

[0076] In some embodiments of the present application, such as Figure 4As shown, the door harness protection device includes a second support portion 6. The second support portion 6 is connected to the second connecting body 3 and is located outside the first communication hole 301.

[0077] It can be understood that when the position where the door harness is plugged into the vehicle computer is within the first communication hole 301, it is easy to cause extrusion to the second connecting body 3 and deform the second connecting body 3. The second support portion 6 can relieve the deformation caused by the above situation and improve the service life.

[0078] In the embodiment of the present application, the number of the second support portions 6 can be two, and the two second support portions 6 are respectively located on the opposite sides of the second connecting body 3.

[0079] Another aspect of the present application provides an automobile, which includes the door harness protection device as described in the above embodiment.

[0080] It can be understood that due to adopting the door harness protection device of the above embodiment, the automobile of the present application has the same technical effects as the above embodiment, and will not be elaborated here.

[0081] In the embodiment of the present application, the automobile can use the engine as the power source, can use the motor as the power source, or can also use the engine and the motor as the power source at the same time.

[0082] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.
