Description

Technical Field

[0001] This application relates to the field of wiring harness technology, and more specifically, to a sliding screen wiring harness connection structure and a vehicle. Background Technology

[0002] In current vehicle models, moving electrical components often use ribbon cables, such as the wiring harness in sliding door structures. However, for large central control screens that require the transmission of high-frequency signals, ribbon cables can cause the bending radius of the wiring harness to be insufficient, thus affecting its performance. During the sliding motion of the car's central control screen, especially when it is a high-definition screen, the ribbon cable method, due to its limitation on the corner radius, can hinder the transmission of high-definition signals. Therefore, a spiral wiring harness design, similar to that used for telephone lines, could be adopted.

[0003] In related technologies, the cross-section of the spiral wire harness is annular, and the positions of the ends of the spiral wire harness relative to the main body of the spiral wire harness are random. That is, the ends may extend at any position on the cross-section. During the expansion and contraction of the spiral wire harness, the line connecting the two ends of the spiral wire harness will become the central axis of the spiral wire harness, causing the spiral wire harness to deviate, which in turn will cause the spiral wire harness to occupy additional space during the arrangement. Summary of the Invention

[0004] This application provides a sliding screen wiring harness connection structure and vehicle, aiming to solve the problem that spiral wiring harnesses occupy additional space during arrangement.

[0005] A first aspect of this application provides a sliding screen wiring harness connection structure, the connection structure comprising:

[0006] First component;

[0007] The first component is slidably disposed on the support portion;

[0008] A helical wire harness, wherein the ends of the helical wire harness extend from the central axis of the helical wire harness, and one end of the helical wire harness is connected to the first component; and

[0009] A tube beam is disposed on one side of the bearing portion. A first fixing member for fixing the spiral wire harness is disposed on the tube beam. The end of the spiral wire harness away from the bearing portion is connected to the first fixing member. The central axis of the spiral wire harness at different positions forms a preset plane. The spiral wire harness extends and retracts on the preset plane, and the connection point between the spiral wire harness and the first fixing member is always located on the central axis of the spiral wire harness.

[0010] Optionally, the bearing portion is provided with a sliding groove, and a mounting base is slidably disposed in the sliding groove. The first component is disposed on the mounting base, and the mounting base is provided with a second fixing member for fixing the spiral wire harness connection. The connection point between the spiral wire harness and the second fixing member is always located on the central axis of the spiral wire harness.

[0011] Optionally, the mounting base is provided with a connector for connecting the first component, and the spiral wire harness is connected to the connector after passing through the second fixing member.

[0012] Optionally, the connector is rotatably configured such that the axis of rotation is perpendicular to the length direction of the slide groove.

[0013] Optionally, a movable groove is provided on the tube beam at the location of the first fixing member, and the spiral wire harness moves within the movable groove.

[0014] Optionally, the spiral wire harness is in a compressed state when the first component is located in the middle position of the support portion, and in a maximum elongated state when the first component is located at both ends of the support portion.

[0015] Optionally, the support portion is provided with a collision protection member for contacting the mounting base.

[0016] Optionally, the support portion is provided with a limiting member for restricting the sliding of the mounting base.

[0018] The sliding screen wiring harness connection structure and vehicle provided in this application include a tube beam for fixing and guiding the wiring harness. A support portion is provided on one side of the tube beam, and a first component is slidably mounted on the support portion. A spiral wiring harness is provided between the tube beam and the first component for transmitting data to the first component while it slides.

The protruding ends of both ends of the spiral wiring harness are located on the central axis of the spiral wiring harness. A first fixing member is provided on the tube beam for fixing the spiral wiring harness. The space between the first fixing member and the support portion is the movement space of the spiral wiring harness during the sliding of the first component. Since the protruding ends of both ends of the spiral wiring harness are located on the central axis of the spiral wiring harness, the spiral wiring harness is always located on the plane between the first fixing member and the support portion during the sliding of the first component and will not shift, thereby reducing the movement space occupied by the spiral wiring harness.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In current vehicle models, moving electrical components often use ribbon cables, such as the wiring harness in sliding door structures. However, for large central control screens that require the transmission of high-frequency signals, ribbon cables can cause the bending radius of the wiring harness to be insufficient, thus affecting its performance. During the sliding motion of the car's central control screen, especially when it is a high-definition screen, the ribbon cable method, due to its limitation on the corner radius, can hinder the transmission of high-definition signals. Therefore, a spiral wiring harness design, similar to that used for telephone lines, could be adopted.

[0028] In related technologies, the cross-section of the spiral wire harness is annular, and the positions of the ends of the spiral wire harness relative to the main body of the spiral wire harness are random. That is, the ends may extend at any position on the cross-section. During the expansion and contraction of the spiral wire harness, the line connecting the two ends of the spiral wire harness will become the central axis of the spiral wire harness, causing the spiral wire harness to deviate, which in turn will cause the spiral wire harness to occupy additional space during the arrangement.

[0029] Example 1

[0030] In view of this, Embodiment 1 of this application provides a sliding screen wiring harness connection structure, referring to... Figure 1 and Figure 2 The connection structure includes:

[0031] First component 4, wherein the first component 4 can be a high-definition screen with sliding settings.

[0032] The first component 4 is slidably disposed on the support part 1.

[0033] The support part 1 is a linear track, and the first component 4 slides on the support part 1 along the length direction of the support part 1.

[0034] The spiral wire harness 2 has its ends extending from the central axis of the spiral wire harness 2, and one end of the spiral wire harness 2 is connected to the first component 4.

[0035] Reference Figure 3 The spiral wire harness 2 can be a telescopic wire harness with a circular cross-sectional projection. In the production process of the spiral wire harness 2, the long wire harness is cut according to the required quantity. After being cut into the required length, the wire harnesses at both ends are processed, that is, the wire ends at both ends are shaped at the central axis position of the spiral wire harness 2. Thus, when the wire ends at both ends are fixed and are on the same plane, no matter how the movement is, the main body of the spiral wire harness 2 always moves on the same plane.

[0036] The tube beam 3 is located on one side of the bearing part 1. The tube beam 3 is provided with a first fixing member 31 for fixing the spiral wire harness 2. The end of the spiral wire harness 2 away from the bearing part 1 is connected to the first fixing member 31. The central axis of the spiral wire harness 2 when it is in different positions forms a preset plane. The spiral wire harness 2 extends and retracts on the preset plane, and the connection point between the spiral wire harness 2 and the first fixing member 31 is always located on the central axis of the spiral wire harness 2.

[0037] The tube beam 3 is a component that fixes the other end of the spiral wire harness 2. It is equipped with a first fixing member 31 for fixing the spiral wire harness 2. The first fixing member 31 can be a snap-fit ​​connector 21, which is fixedly connected to the tube beam 3. The end of the snap-fit ​​connector 21 fixes the spiral wire harness 2. After passing through the first fixing part, the spiral wire harness 2 connects to other components transmitting video via other wire harnesses. In other embodiments, the tube beam 3 can also be a plate or other component, or the spiral wire harness 2 can be directly fixed to the tube beam 3.

[0038] When the spiral wire harness 2 moves, the central axis of the spiral wire harness 2 forms a pre-defined triangular plane. One end of the spiral wire harness 2 is fixed on the first fixing member 31, and the other end slides on the bearing part 1. During the sliding process of the first component 4, since both ends of the spiral wire harness 2 are on the central axis of the spiral wire harness 2, the spiral wire harness 2 will only extend and retract along its own central axis direction when it extends and retracts, and there will be no deviation.

[0039] The shortest distance between the first fixing member 31 and the bearing part 1 is greater than or equal to the shortest distance of the spiral wire harness 2, so that the first component 4 will not compress the spiral wire harness 2 during the sliding process, causing the wire harness to bend and occupy other space.

[0040] The sliding screen wiring harness connection structure and vehicle provided in this application have both extended ends of the spiral wiring harness 2 located on the central axis of the spiral wiring harness 2. The tube beam 3 is provided with a first fixing member 31 for fixing the spiral wiring harness 2. The space between the first fixing member 31 and the bearing part 1 is the activity space of the spiral wiring harness 2 during the sliding of the first component 4. Since both extended ends of the spiral wiring harness 2 are located on the central axis of the spiral wiring harness 2, the spiral wiring harness 2 is always located on the plane between the first fixing member 31 and the bearing part 1 during the sliding of the first component 4, and will not be offset, thereby reducing the activity space occupied by the spiral wiring harness 2.

[0041] In some embodiments, refer to Figure 1 and Figure 4 The bearing part 1 is provided with a sliding groove 11, and a mounting base 12 is slidably disposed in the sliding groove 11. The first component 4 is disposed on the mounting base 12. The mounting base 12 is provided with a second fixing member 13 for fixing the connection of the spiral wire harness 2, and the connection point between the spiral wire harness 2 and the second fixing member 13 is always located on the central axis of the spiral wire harness 2.

[0042] The slide groove 11 is opened along the length direction of the support part 1. The mounting base 12 passes through the slide groove 11 and slides in the slide groove 11, so that the first component 4 and the spiral wire harness 2 can be directly connected through the support part 1. The end of the spiral wire harness 2 is fixed to the mounting base 12 by the second fastener 13.

[0043] The second fixing member 13 can be a snap-fit ​​connector 21, which is fixedly connected to the mounting base 12. The end of the snap-fit ​​connector 21 fixes the spiral wire harness 2. After passing through the second fixing part, the spiral wire harness 2 is connected to the first component 4 through other wire harnesses, thereby preventing the connection point between the first component 4 and the first component 4 from shaking when the first component 4 slides, and improving the stability of the wire harness connection.

[0044] In other embodiments, the support portion 1 may further include a track disposed on the side of the support portion 1, and the mounting base 12 is slidably disposed on the support portion 1. The spiral wire harness 2 is connected to the first component 4 from the side away from the support portion 1. The mounting base 12 may also be connected to the support portion 1 in other ways, as long as the mounting base 12 drives the first component 4 to slide without interfering with the spiral wire harness 2.

[0045] In some embodiments, refer to Figure 1 and Figure 4 The mounting base 12 is provided with a connector 14 for connecting the first component 4. The spiral wire harness 2 is connected to the connector 14 after passing through the second fixing member 13.

[0046] The spiral wire harness 2 is connected to a plug after passing through the second fixing member 13. The plug is inserted into the connector 14. During the sliding process, only the spiral wire harness 2 swings relative to each other. The connection between the plug and the connector 14 is prevented from shaking by the fixing of the second fixing member 13.

[0047] In some embodiments, refer to Figure 1 and Figure 4 The connector 14 is rotatably set, with the axis of rotation perpendicular to the length direction of the slide groove 11.

[0048] After the plug is connected to the connector 14, since the wire end is connected to the spiral wire harness 2, the plug is prone to relative wobbling during the sliding of the first component 4. Therefore, the connector 14 is designed to rotate relative to the plug, and the axis of rotation is perpendicular to the length direction of the slide groove 11. So if the plug wobbles when the first component 4 slides, the connector 14 can rotate synchronously with the plug to avoid loosening at the connection and improve the stability of the entire device during connection.

[0049] In some embodiments, refer to Figure 1 and Figure 5 A movable groove 32 is provided on the pipe beam 3 at the location of the first fixing member 31, and the spiral wire harness 2 moves within the movable groove 32.

[0050] In this embodiment, the first fixing member 31 can be set on the side wall of the tube beam 3. When the first component 4 moves, the spiral wire harness 2 swings continuously. Since the connected end is located at the central axis of the spiral wire harness 2, the body of the spiral wire harness 2 is prone to friction with the tube beam 3 during the swinging process, which causes the spiral wire harness 2 to deviate and wear. Therefore, a movable groove 32 is provided at the location of the first fixing member 31 to allow the spiral wire harness 2 to swing, avoid friction between the spiral wire harness 2 and the tube beam 3, further reduce the space occupied by the spiral wire harness 2 when it moves, and improve the service life of the wire harness.

[0051] In some embodiments, refer to Figure 1 When the first component 4 is located in the middle of the support part 1, the spiral wire harness 2 is in a compressed state; when the first component 4 is located at both ends of the support part 1, the spiral wire harness 2 is in a state of maximum extension.

[0052] In this embodiment, the first fixing member 31 is located on the vertical center line of the slide groove 11, that is, the distance between the first fixing member 31 and the midpoint of the slide groove 11 is the shortest. The length of the spiral wire harness 2 is slightly greater than the distance between the first fixing member 31 and the midpoint of the slide groove 11. Therefore, during the sliding process of the first component 4, the length of the spiral wire harness 2 is the shortest when it slides to the middle position, and the length of the spiral wire harness 2 is the longest when it slides to both ends of the slide groove 11. When the first fixing member 31 is set in other positions, the elongation length of the first component 4 when it slides to one end is greater than the elongation length of the other end, and is also greater than the elongation length of the spiral wire harness 2 after the first component 4 slides to one end when the first fixing member 31 is set in the middle position. Therefore, by setting the first fixing member 31 at the position corresponding to the midpoint of the slide groove 11, the elongation length of the spiral wire harness 2 when the first component 4 slides is reduced, thereby improving the service life of the spiral wire harness 2.

[0053] In some embodiments, the support portion 1 is provided with a collision protection member for contacting the mounting base 12.

[0054] The anti-collision component can be disposed at both ends of the bearing part 1 for contact with the first component 4 or the mounting base 12, or disposed in the slide groove 11 for contact with the mounting base 12. The anti-collision component can be a buffer component with an elastic shape. When the first component 4 slides to both ends, the anti-collision component contacts the mounting base 12 or the first component 4 to reduce the impact on the first component 4.

[0055] In some embodiments, the support portion 1 is provided with a limiting member for restricting the sliding of the mounting base 12.

[0056] The limiting component can restrict the first component 4 during its sliding process by means of friction or snap-fit, so that the first component 4 can stop when it slides to any position and remain stationary when there is no external force pushing it, thereby improving the stability of the entire device.
