Description

Fixing device, vehicle door, vehicle and equipment Technical Field

[0001] The present application relates to the field of machinery, and in particular, to a fixing device, a vehicle door, a vehicle and equipment. Background Art

[0002] With the development of science and technology, conventional items such as glass doors and windows have been given more functions, such as luminous and color-changing functions, touch functions, etc. In order to achieve such functions, the glass needs to be continuously powered by wiring harnesses. However, in application scenarios such as smart cars, the glass often needs to be raised and lowered. During the entire lifting process, one end of the wiring harness is connected to the glass component through a connector, and it stretches or compresses with the movement of the glass. Moreover, during the extension or compression of the wiring harness, there is a possibility of knotting and entanglement with other components that drive the glass to rise and fall. In addition, the wiring harness shakes as the glass rises and falls, and repeatedly hits other components, causing abnormal noises. In addition, the above problems also exist for application scenarios where wiring harnesses are used to power the liftable screens of smart home devices, smartphones, and other devices.

[0003] Therefore, when powering mobile devices such as lifting windows and lifting screens, how to improve the durability of the fixation between the wiring harness and the mobile device, avoid the wiring harness from becoming tangled and entangled with other components, and avoid abnormal noise caused by repeated collisions between the wiring harness and other components, is an urgent problem to be solved.

[0004] Summary of the Invention

[0005] The present application provides a fixing device, a vehicle door, a vehicle and equipment, the purpose of which is to fix the wiring harness on a multi-stage telescopic part through at least one fixed point, so that at least one fixed point shares the force of the wiring harness, and the multi-stage telescopic part is connected to a mobile device, which can improve the durability of the fixing of the wiring harness and the mobile device, avoid the wiring harness from getting tangled with other components, and in addition, can effectively avoid the wiring harness and other components repeatedly hitting each other to cause abnormal noise.

[0006] In a first aspect, a fixing device is provided, which includes: a multi-stage telescopic member, which is composed of a plurality of members that are slidably connected in sequence, wherein the member located at the top is a top member, which is used to be connected to a moving device so that the multi-stage telescopic member can be extended and retracted as the moving device moves; at least one fixed point, which is arranged on the multi-stage telescopic member, and the at least one fixed point is used to fix a wiring harness, wherein one end of the wiring harness is used to be connected to the moving device, and the other end of the wiring harness is used to be connected to a power supply device, so that the power supply device can supply power to the mobile device through the wiring harness.

[0007] For example, the mobile device is an electrical device, and the power supply device needs to connect the mobile device and the power supply device through a wiring harness to achieve continuous power supply to the mobile device. During the movement of the mobile device, the wiring harness will also stretch or compress accordingly.

[0008] For example, one end of the wiring harness can be directly connected to a mobile device, such as through a connector. One end of the wiring harness can also include a lead head, through which the wiring harness is connected to the mobile device. The wiring harness or its lead head can be connected to the connector of the mobile device. The wiring harness or its lead head can also be sealed to the connector, further improving the durability of the fixation between the wiring harness and the mobile device. Similarly, the other end of the wiring harness can be directly connected to a power supply device. The other end of the wiring harness can also include a lead head, through which the wiring harness is connected to the power supply device. The other end of the wiring harness or its lead head can also be sealed to the power supply device, so that the power supply device can supply power to the mobile device through the wiring harness.

[0009] For example, when the multi-stage telescopic member is extended to its longest length, the multi-stage telescopic member as a whole may be wide at the top and narrow at the bottom; or, when the multi-stage telescopic member is extended to its longest length, the multi-stage telescopic member as a whole may be narrow at the top and wide at the bottom.

[0010] For example, the component located at the bottom is the bottom component, and the bottom component may be fixedly connected to the support base or may not be fixedly connected to the support base, that is, it is in a form of virtual connection.

[0011] For example, the wiring harness may be fixed to the aforementioned fixing points by means of buckles, or may be fixed by means of binding belts, or may be fixed by welding or by directly gluing the wiring harness with glue.

[0012] Based on this technical solution, the weight of the wiring harness is partially borne by the fixed points, eliminating the need for the connector between the wiring harness and the mobile device to bear the entire weight of the wiring harness, thereby improving the durability of the connection between the wiring harness and the mobile device. In addition, securing the wiring harness at the fixed points restricts the range of movement of the wiring harness as the mobile device moves.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the component located at the bottom is the bottom component, which is connected to the support base. The above-mentioned fixing device also includes: a rotating shaft, which is arranged between the bottom component and the support base to enable the multi-stage telescopic component to rotate along the axis of the rotating shaft.

[0014] For example, the rotating shaft may be a rotating rod or a pivot shaft.

[0015] Based on the above technical solution, by setting a rotating shaft between the multi-stage telescopic part and the supporting base, the multi-stage telescopic part can automatically adjust its own angle during the movement of the mobile device along the curve, ensuring that the mobile device can move normally along a non-straight track, and avoiding the mobile device from getting stuck or even damaging the multi-stage telescopic part when moving along the curve.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the fixing device further includes: an elastic connecting member, which is arranged between the top component and the moving device so that the multi-stage telescopic member can be pulled and retracted when the moving device moves.

[0017] For example, when the moving device moves along a curve, even if there is no rotating shaft to adjust the angle of the multi-stage telescopic part, since the connecting part between the above-mentioned top part and the above-mentioned moving device is elastic, the force of the moving device in the tangential direction of the curved moving trajectory can be decomposed into a force parallel to the multi-stage telescopic part, so that the multi-stage telescopic part can still be pulled extended or compressed.

[0018] Based on the above technical solution, the top component of the multi-stage telescopic device and the moving device are connected by an elastic connecting member. During the movement of the moving device along the curve, a force parallel to the multi-stage telescopic member can be decomposed through the elastic connecting member, so that the multi-stage telescopic member can still be pulled to stretch or compress, ensuring that the moving device can move normally along the curve, and avoiding the moving device from getting stuck or even damaging the multi-stage telescopic member when moving along a non-straight trajectory.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the number of the at least one fixing point is the same as the number of components included in the multi-stage telescopic member, and each stage of components is provided with a fixing point.

[0020] Based on this technical solution, the weight of the entire wiring harness is shared by the fixed points of each level, further improving the durability of the connection between the wiring harness and the mobile device. In addition, the use of multiple fixed points to secure the wiring harness also restricts the range of movement of the wiring harness during the movement of the mobile device.

[0021] In combination with the first aspect, in certain implementations of the first aspect, the component is a hollow structure for storing a wiring harness.

[0022] Based on the above technical solution, the multi-stage telescopic part is a hollow structure used to store the wiring harness, which further restricts the movement range of the wiring harness, effectively avoiding the wiring harness from getting tangled with other components, and also avoiding the wiring harness from hitting other components and causing abnormal noise.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the above-mentioned fixing device also includes: a first hole, which is arranged at the top component and is used to lead out one end of the wiring harness; and a second hole, which is arranged at the bottom component and is used to lead out the other end of the wiring harness.

[0024] Based on the above technical solution, a relatively closed space is provided for the wiring harness to accommodate the wiring harness, and a first hole and a second hole are set on the multi-stage telescopic part so that the wiring harness is connected to the mobile device and the power supply device respectively, thereby realizing continuous power supply to the mobile device.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the at least one fixed point includes a first fixed point and a second fixed point, wherein the first fixed point is arranged at the top component and the second fixed point is arranged at the bottom component, and when the multi-stage telescopic member is compressed to the shortest state, the wiring harness between the first fixed point and the second fixed point is distributed in a U shape.

[0026] Based on this technical solution, there are no wire harnesses piled up and stacked on top of each other at the bottom part, which can effectively prevent the wire harnesses from getting tangled up on themselves.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the wiring harness is a drag chain wiring harness.

[0028] Based on the above technical solution, the drag chain harness itself has the characteristics of good stability and high durability. Through the weight of the drag chain itself, it can also play a corresponding restraining role on the harness itself, making it difficult for the harness to get tangled.

[0029] In combination with the first aspect, in certain implementations of the first aspect, a first opening is provided on a surface of the component.

[0030] For example, the surface of the component can be a large surface of the component, which is the surface with the largest area in the component, or can be other surfaces. Due to the restraint of the drag chain harness itself, under normal circumstances, even if the first opening is provided on the surface of the component, the drag chain harness will not overflow from the first opening during the process of stretching or compressing the drag chain harness.

[0031] Based on the above technical solution, since the drag chain harness has the characteristic of self-constraint harness, the drag chain harness is not easy to overflow from the first opening on the surface of the component and become knotted and entangled with other components. Furthermore, the multi-stage telescopic parts are lightweight to a certain extent, the overall fixing device is lighter, and the manufacturing cost is reduced.

[0032] In combination with the first aspect, in certain implementations of the first aspect, the above-mentioned component is a baffle, and the above-mentioned fixing device also includes: a storage portion, one side of the storage portion has a second opening, and the second opening is arranged opposite to the multi-stage telescopic part. When the multi-stage telescopic part is extended to the longest state, the range of the second opening covers all at least one fixed point set on the multi-stage telescopic part.

[0033] For example, the storage portion may be a box-shaped structure, for example, a wire harness box having a second opening on one side.

[0034] For example, the side with the second opening can be the large surface of the receiving portion or the side surface of the receiving portion, wherein the side surface is a surface connected to the large surface except the upper end surface or the lower end surface of the receiving portion.

[0035] Based on the above technical solution, the above-mentioned storage portion is used to store the wiring harness fixed on the multi-stage telescopic part, further limiting the movement range of the wiring harness when the mobile device moves, which can effectively prevent the wiring harness from being entangled with other components, and also avoid the wiring harness from hitting other components and causing abnormal noise.

[0036] In combination with the first aspect, in certain implementations of the first aspect, the lower end of the second opening is connected to the bottom component, and the fixing device further includes: a third hole, which is arranged at the upper end or the top component of the storage portion, for leading out one end of the wiring harness; and a fourth hole, which is arranged at the lower end or the bottom component of the storage portion, for leading out the other end of the wiring harness.

[0037] Based on the above technical solution, a relatively closed space is provided for the wiring harness to store the wiring harness, and a third hole and a fourth hole are set on the multi-stage telescopic part or the storage part, so that the wiring harness is connected to the mobile device and the power supply device respectively, thereby realizing continuous power supply to the mobile device.

[0038] In combination with the first aspect, in certain implementations of the first aspect, the above-mentioned fixing device also includes: a pressure plate, which is arranged on the top part and extends toward the interior of the storage portion to prevent the wire harness from overflowing from the second opening during the compression process of the multi-stage telescopic part.

[0039] For example, when the top component is provided with a fixing point, the pressure plate can be disposed above the fixing point of the top component. The pressure plate can also be disposed directly on the upper end surface of the top component. For example, when the top component is not provided with a fixing point but the next-level component of the top component is provided with a fixing point, the pressure plate can be disposed on the top component or above the fixing point of the next-level component.

[0040] Based on the above technical solution, it is possible to effectively prevent the wire harness from running around in the storage portion during the compression process, causing the wire harness to overflow the storage portion, and further causing the wire harness to become tangled and entangled with other components.

[0041] In combination with the first aspect, in certain implementations of the first aspect, the storage portion and the slide rail of the mobile device are integrally formed.

[0042] Based on the above technical solution, the storage portion is used as a part of the slide rail, which saves the space occupied by the device.

[0043] In combination with the first aspect, in certain implementations of the first aspect, the wiring harness is a flat wiring harness.

[0044] Based on the above technical solution, since flat wire harnesses are easy to bend and easy to stack on each other after bending, the use of flat wire harnesses can effectively avoid the problem of the wire harnesses getting entangled and knotted as the mobile device moves, and can also avoid the problem of the wire harnesses getting entangled and knotted with other components.

[0045] In a second aspect, a vehicle door is provided, comprising: a fixing device and a moving device as in any possible implementation of the first aspect.

[0046] In combination with the second aspect, in certain implementations of the second aspect, the moving device included in the vehicle door is a liftable door glass, and the liftable door glass is connected to the fixing device.

[0047] In combination with the second aspect, in certain implementations of the second aspect, the liftable door glass is connected to the fixing device via an elastic connector.

[0048] In a third aspect, a vehicle is provided, comprising the fixing device as in any possible implementation manner of the first aspect, or the vehicle door as in any possible implementation manner of the second aspect.

[0049] In a fourth aspect, a device is provided, comprising a fixing device as in any possible implementation of the first aspect.

[0050] For example, the above-mentioned device may be a display screen, a television, a curtain, architectural glass, a roof skylight, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] FIG11 is a schematic structural diagram of another fixing device 200 provided in an embodiment of the present application. DETAILED DESCRIPTION

[0062] The technical solution in this application will be described below with reference to the accompanying drawings.

[0063] The fixing device 200 provided in the present application is suitable for use in a vehicle and is used in conjunction with the vehicle's lifting window. The vehicle (sometimes referred to as a vehicle) in the present application is a vehicle in a broad sense, which can be a means of transportation (such as: cars, trucks, motorcycles, trains, airplanes, ships, etc.), industrial vehicles (such as: forklifts, trailers, tractors, etc.), engineering vehicles (such as: excavators, bulldozers, cranes, etc.), agricultural equipment (such as mowers, harvesters, etc.), amusement equipment, toy vehicles, etc. This application does not limit the type of vehicle. In addition, the fixing device 200 provided in the present application is also suitable for scenarios where it moves, extends, or compresses following other powered objects.

[0064] Taking the scenario of powering the door glass of a vehicle as an example, in order to realize the electrochromic, touch and other functions of the door glass, it is necessary to continuously power the door glass. Figure 1 shows a schematic diagram of a method of continuously powering the mobile device 110 provided by an embodiment of the present application. Normally, the power supply device 120 of the vehicle is connected to the mobile device 110 through a wiring harness 130, wherein the power supply device 120 can be a battery of the vehicle, or a battery device used alone to power the mobile device 110, and this embodiment of the present application does not limit this. The mobile device 110 can be the door glass of a vehicle, and further, the wiring harness 130 and the mobile device 110 can be connected through a connector 140. When the mobile device 110 rises, the wiring harness 130 stretches as the mobile device 110 rises, and when the mobile device 110 descends, the wiring harness 130 compresses as the mobile device 110 descends. However, during the process of the mobile device 110 rising and falling, the following problems will arise:

[0065] 1) Knotting and entanglement problem: After the mobile device 110 descends, the wire harness 130 will compress itself, causing the bent portion of the wire harness 130 and the door sheet metal accessories, such as the glass lift guide rail, the door reinforcement beam, etc., to become tangled and entangled, thereby causing the wire harness 130 to be bound. Thereafter, if the mobile device 110 ascends, the wire harness 130 may be pulled apart.

[0066] 2) Durability Issues: During the raising and lowering of the mobile device 110, the connector 140 between the wiring harness 130 and the mobile device 110 must bear the weight of the wiring harness 130. Especially when the mobile device 110 reaches its limit of ascent, the fixed point may need to bear the entire weight of the wiring harness 130. Therefore, during the repeated raising and lowering of the door glass, the durability of the connection between the wiring harness 130 and the connector 140 cannot be guaranteed.

[0067] 3) Problem of controlling abnormal noise caused by the hanging shaking of the wire harness 130: When the mobile device 110 is raised or lowered, the wire harness 130 will shake, and the shaking of the wire harness 130 will repeatedly collide with the surrounding parts, causing abnormal noise.

[0068] The above is an example of a scenario of powering the vehicle door glass to illustrate the current problems in this scenario. Similarly, in other application scenarios, such as the lifting and lowering of a robotic arm, the above problems also exist in scenarios where the mobile device 110 needs to be continuously powered through the wire harness 130. However, the existing technical solutions all have defects such as complex processes, difficulty in mass production, and poor durability. In view of this, the present application provides a fixing device 200, which uses a multi-stage telescopic member 210 to allow the wire harness 130 to follow the mobile device 110 during movement to avoid knotting and entanglement with other components, and multiple fixing points for fixing the wire harness 130 are set on the multi-stage telescopic member 210 to share the force on the wire harness 130, thereby improving the durability of the connection between the wire harness 130 and the mobile device 110. In addition, the device 200 for constraining the wire harness 130 can also effectively prevent the wire harness 130 from repeatedly hitting other components to cause abnormal noise.

[0069] The embodiment of the present application takes the continuous power supply to the mobile device 110 through the wire harness 130 as an application scenario, and describes the device 200 for constraining the wire harness 130 provided in the embodiment of the present application.

[0070] Figure 2 is a schematic diagram of the structure of a fixing device 200 provided in an embodiment of the present application. Figure 2 is a side cross-sectional view of the fixing device 200, wherein Figure 2 (a) shows the structure of the fixing device 200 when it is extended to its longest state as the mobile device 110 moves, Figure 2 (b) shows the structure of the fixing device 200 when it is compressed to its shortest state as the mobile device 110 moves, and Figure 2 (c) shows the setting of the fixing points when the wiring harness 130 is too long.

[0071] The device 200 includes:

[0072] The multi-stage telescopic member 210 is composed of a plurality of components that are slidably connected in sequence, wherein the topmost component is a top component 211, which is used to connect to the moving device 110 so that the multi-stage telescopic member 210 can extend and retract as the moving device 110 moves;

[0073] At least one fixed point 220 is arranged on the multi-stage telescopic member 210, and the at least one fixed point 220 is used to fix the wiring harness 130, wherein one end of the wiring harness 130 is used to connect with the above-mentioned mobile device 110, and the other end of the wiring harness 130 is used to connect with the power supply device 120, so that the power supply device 120 supplies power to the above-mentioned mobile device 110 through the wiring harness 130.

[0074] The top component 211 refers to the component located at the top of the entire multi-stage telescopic component 210 when the multi-stage telescopic component 210 is extended to its longest state in a direction perpendicular to the ground.

[0075] In one embodiment, the mobile device 110 is an electrical device, and the power supply device 120 needs to connect the mobile device and the power supply device 120 through a wiring harness 130 to achieve continuous power supply to the mobile device 110. During the movement of the mobile device 110, the wiring harness 130 will also stretch or compress accordingly.

[0076] In some possible embodiments, one end of the wiring harness 130 may be directly connected to the mobile device 110, for example, via a connector. One end of the wiring harness 130 may also include a lead, through which the wiring harness 130 is connected to the mobile device 110. The wiring harness 130 or its lead may be connected to the connector 140 of the mobile device 110. The wiring harness 130 or its lead may be sealed to the connector 140, further improving the durability of the connection between the wiring harness 130 and the mobile device 110. Similarly, the other end of the wiring harness 130 may be directly connected to the power supply device 120. The other end of the wiring harness 130 may also include a lead, through which the wiring harness 130 is connected to the power supply device 120. The other end of the wiring harness 130 or its lead may be sealed to the power supply device 120, allowing the power supply device 120 to supply power to the mobile device 110 through the wiring harness 130.

[0077] In some possible embodiments, the multi-stage telescopic member 210 includes N stages of components that are slidably connected in sequence, wherein the width of the i-th stage component is greater than the width of the i-1-th stage component, that is, when the multi-stage telescopic member 210 is extended to its longest length, the multi-stage telescopic member 210 as a whole presents a shape that is wide at the top and narrow at the bottom; the width of the i-th stage component in the multi-stage telescopic member 210 may also be less than the width of the i-1-th stage component, that is, when the multi-stage telescopic member 210 is extended to its longest length, the multi-stage telescopic member 210 as a whole presents a shape that is narrow at the top and wide at the bottom. This embodiment of the present application does not limit this, wherein i is a positive integer greater than 1 and less than or equal to N.

[0078] For ease of description, the following description will be made by taking the movable device 110 as a lifting glass of a vehicle door as an example, wherein the bottom component 212 of the fixing device 200 may be connected to a support base, which may be a vehicle door sheet metal.

[0079] As shown in FIG2(a), in one embodiment, the multi-stage telescopic member 210 is comprised of N components that are sequentially slidably coupled, where N is a positive integer greater than 1. During the raising of the glass, the top of the Nth stage component of the multi-stage telescopic member 210 is in contact with the glass, so the Nth stage component is first pulled up by the glass. When the Nth stage component is raised to its highest position, the Nth stage component pulls up the N-1th stage component, causing the entire multi-stage telescopic member 210 to continue extending. This continues in this manner until the glass reaches its highest position, at which point the multi-stage telescopic member 210 is extended to its longest position. The Nth stage component is the top component 211, which can be connected to the glass directly or to the glass slider 111 shown in FIG2(c), which is disposed on the glass rail and fixed to the glass to drive the glass upward and downward. Of course, the specific connection method between the top component 211 and the lifting glass can be bonding or connection through other connecting parts, as long as it plays the role of connecting the top component 211 and the lifting glass. This embodiment of the application does not limit this.

[0080] Conversely, as shown in FIG2(b), during the lowering of the glass, the second-stage through the Nth-stage components descend as a whole with the glass. When the second-stage component first descends to its lowest position, the third-stage through the Nth-stage components, due to the sequential sliding engagement between the components, continue to descend as a whole with the glass, and so on, until the glass reaches its lowest position. At this point, the multi-stage telescopic member 210 can be compressed to its shortest position, with the various stages of the multi-stage telescopic member 210 sequentially contained. Because the bottom member 212 is fixedly connected to the door sheet metal, the bottom member 212 is not pulled up during the raising and lowering of the glass.

[0081] In the above embodiment, the bottom component 212 is fixedly connected to the door sheet metal. In other possible embodiments, the bottom component 212 may not be fixedly connected to the door sheet metal, that is, it may be a virtual connection, which is also applicable to the above technical solution. Similarly, the bottom component 212 is not necessarily fixedly connected to the door sheet metal; other components other than the top component 211 may be fixed to the door sheet metal, and this embodiment of the application is not limited to this.

[0082] In some possible embodiments, as the lifting glass continues to rise, when the i-th level component is pulled up to the highest position, it is necessary to pull up the i-1-th level component through a connecting member. The connecting member can be a structural schematic diagram of another fixing device 200 provided in an embodiment of the present application as shown in Figure 3. Figure 3 shows a front view of the fixing device 200.

[0083] In the example shown in FIG3 , i equals N. The connector includes a slide rail 230 and a fixing buckle 240. The fixing buckle 240 can be disposed at the lower end of the i-th level component, while the slide rail 230 can be disposed at the i-1th level component. The slide rail 230 is a linear slide rail parallel to the telescopic direction of the multi-stage telescopic member 210. The slide rail 230 can extend from the upper end to the lower end or from the upper end to the middle of the i-1th level component. The projection of the fixing buckle 240 on the i-1th level component is aligned with the slide rail.

[0084] In addition, the connecting member may be a structural diagram of another fixing device 200 provided in an embodiment of the present application as shown in Figure 4. Figure 4 shows a front view of the fixing device 200.

[0085] In the example shown in FIG4 , i is equal to N. The connection structure includes a first bridging member 251 and a second bridging member 252, wherein the first bridging member 251 is disposed at the lower end of the i-th level component, and the second bridging member 252 is disposed at the upper end of the i-1-th level component. In addition, the connection structure proposed in this application may also be in other forms, which are not limited in this application.

[0086] In some possible embodiments, the connector between the aforementioned i-th level component and the i-1-th level component may be provided below the fixing point of the i-1-th level component, that is, when the multi-stage telescopic member 210 is compressed to its shortest, the wiring harness 130 will not be stuck in the interlayer between the aforementioned components. Alternatively, as shown in FIG5 , a structural schematic diagram of another fixing device 200 provided in an embodiment of the present application is provided, and FIG5 shows a front view of the fixing device 200. The fixing points are provided in the side edge regions of the components at each level, and the edge regions are not the overlapping regions between the components when the components at this level are sequentially contained with the components at the previous level or the next level. This structure can also prevent the wiring harness 130 from being stuck in the interlayer between the components.

[0087] In some possible embodiments, the wiring harness 130 can be fixed to the above-mentioned fixed points by means of buckles, or by means of straps, or by means of welding or direct gluing. The embodiments of the present application do not limit the specific method of fixing the wiring harness 130 to the fixed points.

[0088] Based on the above technical solution, since the device provided in the embodiment of the present application includes the aforementioned fixing points, a portion of the weight of the wiring harness 130 is borne by the fixing points, thereby preventing the entire weight of the wiring harness 130 from being borne by the connector between the wiring harness 130 and the vehicle door lift window. This improves the durability of the connection between the leads of the wiring harness 130 and the mobile device 110. In addition, the fixing points secure the wiring harness 130, restricting the range of movement of the wiring harness 130 as the mobile device 110 moves.

[0089] In some possible embodiments, each stage of the multi-stage telescopic member 210 is provided with one of the aforementioned fixing points. Furthermore, as shown in FIG2(c), when the wiring harness 130 is too long, multiple fixing points may be provided on the first stage of the member, allowing the wiring harness 130 to be bent to an appropriate length through the fixing points.

[0090] In some possible embodiments, when the multi-stage telescopic member 210 is extended to the longest state, the wire harness 130 between the various fixing points is always in a relaxed state.

[0091] Based on the above technical solution, the weight of the entire wiring harness 130 is shared by the fixing points of each level component, further improving the durability of the connection between the wiring harness 130 and the mobile device 110. In addition, fixing the wiring harness 130 at multiple fixing points also restricts the range of movement of the wiring harness 130 during the movement of the mobile device 110.

[0092] FIG6 is a schematic structural diagram of a fixing device 200 provided in an embodiment of the present application.

[0093] The above device also includes:

[0094] The rotating shaft 260 is disposed between the outer surface of the bottom component 212 and the support base 150 , connects the bottom component 212 and the support base 150 , and enables the multi-stage telescopic member 210 to rotate along the axis of the rotating shaft 260 .

[0095] Similar to the top component 211 located at the top, the component located at the bottom refers to the component located at the bottom of the entire multi-stage telescopic component 210 when the multi-stage telescopic component 210 is extended to its longest state along a direction perpendicular to the ground.

[0096] Taking the mobile device 110 as an example of a lifting glass of a car door, since the outer shells of most vehicles are set to be streamlined, the lifting trajectory of the lifting glass of the car door is a curve. If the multi-stage telescopic component 210 is directly fixed to the car door sheet metal, it cannot be ensured that the multi-stage telescopic component 210 can be raised and lowered with the lifting glass, thereby causing the glass to get stuck or even damage the multi-stage telescopic component 210 during the lifting process.

[0097] Therefore, the outer surface of the bottom component 212 is connected to the door sheet metal via a rotating shaft 260. The rotating shaft 260 can be a rotating rod or a pivot shaft, which is not limited in this embodiment of the present application.

[0098] When the lifting glass rises along the curve, it drives the Nth stage component to rise while also driving the shaft 260 to rotate along the axis, thereby adjusting the angle of the multi-stage telescopic component 210 to ensure that the glass can still be effectively lifted and lowered during the process of lifting and lowering along the curve.

[0099] In some possible embodiments, when the mobile device 110 is an electrical device other than the aforementioned lifting window, the mobile device 110 may move along an irregular trajectory, and the technical solutions provided in the aforementioned embodiments are also applicable.

[0100] Based on the above technical solution, by setting a rotating shaft 260 between the multi-stage telescopic member 210 and the support base 150, it is ensured that when the mobile device 110 moves along a non-straight track, the multi-stage telescopic member 210 can automatically adjust its own angle, ensuring that the mobile device 110 can move normally along the non-straight track, and avoiding the mobile device 110 from getting stuck or even damaging the multi-stage telescopic member 210 when moving in a curve.

[0101] FIG7 shows a schematic structural diagram of another fixing device 200 provided in an embodiment of the present application.

[0102] The fixing device 200 may further include:

[0103] The elastic connector 270 is disposed between the top member 211 and the moving device 110 to enable the multi-stage telescopic member 210 to be pulled and extended when the moving device 110 moves along a curve. This embodiment is applicable when no rotating shaft 260 is disposed between the bottom member 212 of the multi-stage telescopic member 210 and the support base 150.

[0104] When the mobile device 110 moves along a curve, even if there is no rotating shaft 260 to adjust the angle of the multi-stage telescopic member 210, since the connecting member between the above-mentioned top component 211 and the above-mentioned mobile device 110 is elastic, the force F of the mobile device 110 in the tangential direction of the curved movement trajectory can be decomposed into a force F1 parallel to the multi-stage telescopic member 210, so that the multi-stage telescopic member 210 can still be pulled by the mobile device 110 to extend or compress.

[0105] In some possible embodiments, when the mobile device 110 is an electrical device other than the aforementioned window lift, the mobile device 110 can move along an irregular trajectory, and the technical solution provided in the above embodiment is also applicable. Of course, when a rotating shaft 260 is provided between the bottom component 212 and the support base 150, the technical solution provided in this embodiment is also applicable.

[0106] Based on the above technical solution, the top component 211 of the multi-stage telescopic device and the moving device 110 are connected by an elastic connecting member 270 to ensure that during the movement of the moving device 110 along a non-linear trajectory, a force F1 parallel to the multi-stage telescopic member 210 can be decomposed through the elastic connecting member 270, so that the multi-stage telescopic member 210 can still be pulled to stretch or compress, ensuring that the moving device 110 can move normally along the non-linear trajectory, and avoiding the moving device 110 from being stuck or even damaging the multi-stage telescopic member 210 when moving along the non-linear trajectory.

[0107] Figure 8 shows a structural schematic diagram of another fixing device 200 provided in an embodiment of the present application. In this embodiment, the fixing device 200 includes a multi-stage telescopic member 210, each stage of which is a hollow structure. For example, the hollow structure can be a structure in the form of a wire harness box for storing the wire harness 130.

[0108] In some possible embodiments, when the above-mentioned multi-stage telescopic member 210 is composed of two components that are slidably connected in sequence, since the top component 211 and the bottom component 212 are slidably connected, the lower end surface of the top component 211 and the upper end surface of the bottom component 212 are both non-closed, so that the wiring harness 130 can pass through the various levels of components of the entire multi-stage telescopic member 210. Figure 9 shows a structural schematic diagram of another fixing device 200 provided by an embodiment of the present application, wherein the upper end surface of the top component 211 can also be non-closed, thereby leading out one end of the wiring harness 130, so that this end of the wiring harness 130 is connected to the mobile device 110. Of course, the upper end surface of the top component 211 can also be closed, but a first hole 310 needs to be set to lead out one end of the wiring harness 130, so that this end of the wiring harness 130 is connected to the mobile device 110, thereby better storing the wiring harness 130. Since the bottom part 212 is in contact with the support base 150, the wiring harness 130 will not fall out of the multi-stage telescopic member 210 during the compression process regardless of whether the lower end surface of the bottom part 212 is closed. Therefore, the bottom part 212 needs to be provided with a second hole 320 to lead out the other end of the wiring harness 130 so that this end of the wiring harness 130 is connected to the power supply device 120, thereby achieving continuous power supply to the mobile device 110.

[0109] When the multi-stage telescopic member 210 is composed of two or more components that are slidably connected in sequence, for the sake of convenience, in the embodiment of the present application, the components other than the top component 211 and the bottom component 212 of the multi-stage telescopic member 210 are collectively referred to as intermediate components. Since the multi-stage telescopic member 210 is composed of multiple components that are slidably connected in sequence, the upper and lower end surfaces of these intermediate components are all open, so that the wire harness 130 can pass through the components of each level of the multi-stage telescopic member 210. Among them, the upper end surface of the top component 211 can also be open, thereby leading out one end of the wire harness 130, so that this end of the wire harness 130 is connected to the mobile device 110. Of course, the upper end surface of the top component 211 can also be closed, but it is necessary to provide a first hole 310 to lead out one end of the wire harness 130, so that this end of the wire harness 130 is connected to the mobile device 110. Since the bottom part 212 is in contact with the support base 150, the wiring harness 130 will not fall out of the multi-stage telescopic member 210 during the compression process regardless of whether the lower end surface of the bottom part 212 is closed. Therefore, the bottom part 212 needs to be provided with a second hole 320 to lead out the other end of the wiring harness 130 so that this end of the wiring harness 130 is connected to the power supply device 120, thereby achieving continuous power supply to the mobile device 110.

[0110] Based on the above technical solution, the multi-stage telescopic part 210 is a hollow structure for storing the wiring harness 130, further restricting the movement range of the wiring harness 130, effectively avoiding the wiring harness 130 from getting tangled with other components, and also avoiding the wiring harness 130 from hitting other components and causing abnormal noise.

[0111] Figure 10 shows a schematic diagram of the structure of another fixing device 200 provided in an embodiment of the present application. Figure 10 (a) is a schematic diagram of the structure of the multi-stage telescopic member 210 in the extension process, Figure 10 (b) is a schematic diagram of the structure of the multi-stage telescopic member 210 when compressed to its shortest state, Figure 10 (c) is a cross-sectional view of the first cross-section in (a), Figure 10 (d) is a cross-sectional view of the second cross-section in (a), and Figure 10 (e) is a schematic diagram of the shape of the wiring harness 130 provided in the device shown in Figure 10. The multi-stage telescopic member 210 shown in Figure 10 is composed of two-stage components.

[0112] Based on the fixing device 200 provided in the above embodiment, the above-mentioned wiring harness 130 can be a drag chain wiring harness. The drag chain wiring harness itself has good stability. Through the weight of the drag chain, it also plays a corresponding restraining role on the wiring harness 130 itself, making it difficult for the wiring harness 130 to get knotted and entangled.

[0113] Therefore, the surface of each level component provided in the above embodiment may further be provided with a first opening 330. The surface may be the large surface of the component, which is the surface with the largest area in the component. Due to the restraint of the drag chain harness itself, under normal circumstances, even if the first opening is provided on the surface of the component, the drag chain harness will not overflow from the first opening during the process of stretching or compressing the drag chain harness.

[0114] The cross-sectional view of the fixing device 200 at the first cross-section is shown in FIG10(c), wherein the cross-section of the portion indicated by 1010 in the figure is a cross-sectional view of the drag chain harness along the first cross-sectional view, wherein the cross-sectional view of the drag chain harness on the left is a cross-sectional view of the drag chain harness at one end fixed to the top component 211, and the cross-sectional view of the drag chain harness on the right is a cross-sectional view of the drag chain harness at the other end fixed to the bottom component 212. In addition, the cross-sectional view of the fixing device 200 at the second cross-sectional view is shown in FIG10(d), wherein the cross-sectional view of the portion indicated by 1010 in the figure is a cross-sectional view of the drag chain harness along the second cross-sectional view. However, since the second cross-sectional view does not capture the other end of the drag chain harness fixed to the bottom component 212, only the cross-sectional view of the drag chain harness at one end fixed to the top component 211 is presented in this schematic view. In addition, it can be seen from (c) and (d) of Figure 10 that the first openings 330 provided at each level of components are provided on the surface in the same direction. Of course, they can also be provided in alternating directions, which is not limited in this application.

[0115] Based on the above technical solution, since the drag chain harness has the characteristic of constraining the harness itself, the drag chain harness is not easy to overflow from the first opening 330 on the surface and become entangled with other components. Furthermore, the multi-stage telescopic part 210 is lightweight to a certain extent, making the fixing device 200 as a whole lighter and reducing the manufacturing cost.

[0116] In some possible embodiments, the at least one fixed point 220 includes a first fixed point 221 and a second fixed point 222. The first fixed point 221 can be set above the top part 211, and the second fixed point 222 can be set above the bottom part 212. When the multi-stage telescopic part 210 is compressed to the shortest state, the first fixed point 221 and the second fixed point 222 can be spatially located on the same plane perpendicular to the telescopic direction of the multi-stage telescopic part 210. At this time, since the two fixed points are fixed, the drag chain harness can be adjusted by adjusting the length of the drag chain harness to make the drag chain harness as a whole present a U-shaped distribution.

[0117] Based on this technical solution, there are no drag chain harnesses piled up and stacked together in the bottom part 212, which can effectively prevent the harness 130 from being entangled with itself.

[0118] Based on the fixing device 200 proposed in the above embodiment, when the above-mentioned wiring harness 130 is too long, a drag chain can be added for the wiring harness 130 of appropriate length, that is, according to the movement of the moving device 110 connected to the wiring harness 130, the length of the wiring harness 130 that needs to be installed with the drag chain is determined. As shown in (e) in Figure 10, a drag chain is installed for part of the wiring harness 130. Under the fixing action of the first fixed point 221 and the second fixed point 222, as well as the action of the drag chain's own weight, this part of the wiring harness 130 is allowed to droop freely with the drag chain. The left picture shows the state of the drag chain wiring harness in the fixing device 200 when the wiring harness 130 is in an extended state, and the right picture shows the state of the drag chain wiring harness as a whole when the multi-stage telescopic member 210 is compressed to the shortest state. As for the excess wiring harness 130, as shown in Figures 10(c) and 10(d), a wiring harness slot 1020 can be provided below the second fixing point 222 of the bottom member 212. This wiring harness slot is connected to the second hole 320 of the bottom member 212, so that the excess wiring harness 130 is stored in the wiring harness slot and connected to the power supply device 120 through the second hole 320. Based on this technical solution, the excess wiring harness 130 can be effectively prevented from becoming tangled and entangled in the multi-stage telescopic member 210.

[0119] In some possible embodiments, the bottom part 212 of the multi-stage telescopic member 210 is connected to the support base 150 via the rotating shaft 260, or the top part 211 of the multi-stage telescopic member 210 is directly connected to the mobile device 110 via an elastic connector 270. Based on this technical solution, the multi-stage telescopic member 210 can still be stretched or compressed when the mobile device 110 moves in a curve, thereby preventing the mobile device 110 from getting stuck or even being damaged when moving along a non-linear trajectory.

[0120] Figure 11 is a structural schematic diagram of another fixing device 200 provided in an embodiment of the present application, wherein (a) in Figure 11 is a structural schematic diagram of the multi-stage telescopic member 210 when it is extended to its longest state, and the structural schematic diagram is a side sectional view of the fixing device 200, (b) in Figure 11 is a front view of the multi-stage telescopic member 210 when it is extended to its longest state, (c) in Figure 11 is a rear view of the multi-stage telescopic member 210 when it is extended to its longest state, (b) in Figure 11 is a structural schematic diagram of the multi-stage telescopic member 210 when it is compressed to its shortest state, and (c) in Figure 11 is a front view of the multi-stage telescopic member 210 when it is extended to its longest state. d) is a structural schematic diagram of the multi-stage telescopic part 210 when it is compressed to its shortest state, which is a side sectional view of the fixing device 200. (e) in Figure 11 is a front view of the multi-stage telescopic part 210 when it is compressed to its shortest state. (f) in Figure 11 is a rear view of the multi-stage telescopic part 210 when it is compressed to its shortest state. (g) in Figure 11 is a structural schematic diagram of the multi-stage telescopic part 210 when it is not connected to the storage part 410. (h) in Figure 11 is a structural schematic diagram of a fixing device 200 with a pressure plate 450 provided in an embodiment of the present application.

[0121] Different from the fixing device 200 shown in FIG10 , the fixing device 200 proposed in this embodiment includes a multi-stage telescopic member 210 in which each stage component is a baffle. In addition, the device 200 further includes:

[0122] The storage portion 410 has a second opening 420 on one side. The second opening 420 is arranged opposite to the multi-stage telescopic member 210. When the multi-stage telescopic member 210 is extended to its longest state, the range of the second opening 420 covers all the fixed points set on the above-mentioned multi-stage telescopic member 210.

[0123] In one embodiment, the storage portion 410 may be a box-shaped structure, for example, a wire harness box having a second opening 420 on one side. The side having the second opening 420 may be the main surface of the storage portion 410 or a side surface of the storage portion 410. The side surface refers to a surface connected to the main surface, excluding the upper end surface or the lower end surface of the storage portion 410.

[0124] Based on the above technical solution, the above-mentioned storage portion 410 is used to store the wiring harness 130 fixed on the multi-stage telescopic part 210, further limiting the movement range of the wiring harness 130 when the mobile device 110 moves, which can effectively prevent the wiring harness 130 from being entangled with other components, and also avoid the wiring harness 130 from hitting other components and causing abnormal noise.

[0125] In some possible embodiments, the storage portion 410 can be fixed to the same support base 150 as the multi-stage telescopic member 210, or the storage portion 410 can be fixedly connected to another base device, as long as the range of the second opening 420 covers all the fixing points set on the multi-stage telescopic member 210, so as to prevent the wire harness 130 from getting stuck in the interlayer between the storage portion 410 and the multi-stage telescopic member 210 during the expansion and contraction of the multi-stage telescopic member 210. Therefore, under the premise of meeting the above conditions, the height of the storage portion 410 can be higher than the height of the multi-stage telescopic member 210 in the longest state, can be equal to the height of the multi-stage telescopic member 210 in the longest state, and can also be lower than the height of the multi-stage telescopic member 210 in the longest state.

[0126] In some possible embodiments, the multi-stage telescopic member 210 and the storage portion 410 can be connected via the above-mentioned rotating shaft 260, or the multi-stage telescopic member 210 and the support base 150 can be connected via the above-mentioned rotating shaft 260, or the top component 211 of the multi-stage telescopic member 210 can be directly connected to the mobile device 110 via an elastic connecting member 270; the above-mentioned storage portion 410 and the multi-stage telescopic member 210 can also be integrally formed, and the integrally formed device can be connected to the support base 150 via the rotating shaft 260, or the top component 211 of the multi-stage telescopic member 210 in the above-mentioned integrally formed device can be directly connected to the mobile device 110 via an elastic connecting member 270.

[0127] Based on this technical solution, the multi-stage telescopic member 210 can still be stretched or compressed when the mobile device 110 moves in a curve, thereby preventing the mobile device 110 from being stuck or even damaged when moving along a non-straight line.

[0128] In some possible embodiments, as shown in (a) and (d) of FIG. 11 , the fixing device 200 further includes:

[0129] The third hole 430 is provided at the upper end of the storage portion 410 or the top component 211 and is used to lead out one end of the wiring harness 130 ; this end can be connected to the mobile device 110 .

[0130] Fourth hole 440 , cover The fourth hole 440 is provided at the lower end of the storage portion 410 or the bottom component 212 for leading out the other end of the wiring harness 130 ; this end can be connected to the power supply device 120 .

[0131] Based on the above technical solution, continuous power supply to the mobile device 110 can be achieved.

[0132] In some possible embodiments, as shown in (g) in Figure 11, when the above-mentioned storage portion 410 and the multi-stage telescopic member 210 are two independent devices, the gap between the storage portion 410 and the multi-stage telescopic member 210 can be smaller than the diameter of the above-mentioned wiring harness 130 and larger than the diameter of the lead wires led out from the two ends of the above-mentioned wiring harness 130, so that the lead wires led out from the above-mentioned two ends of the wiring harness 130 can pass through the gap, and then the lead wires led out from one end of the wiring harness 130 are connected to the mobile device 110, and the lead wires led out from the other end of the wiring harness 130 are connected to the power supply device 120.

[0133] Based on the above technical solution, continuous power supply to the mobile device 110 can also be achieved. Since the storage portion 410 and the multi-stage telescopic member 210 are two independent devices, it is convenient for the two devices to be maintained separately in the future, and there is no need to drill holes in the fixing device 200, which simplifies the processing technology of the fixing device 200.

[0134] As shown in FIG. 11( h ), an embodiment of the present application provides a fixing device 200 having a pressing plate 450 , wherein the fixing device 200 further includes:

[0135] The pressing plate 450 is provided on the top component 211 and extends toward the interior of the storage portion 410 to prevent the wire harness 130 from overflowing from the second opening 420 of the storage portion 410 during the compression of the multi-stage telescopic member 210 .

[0136] In some possible embodiments, when the top component 211 is provided with a fixing point, the pressing plate 450 can be disposed above the fixing point of the top component 211. The pressing plate 450 can also be disposed directly on the upper end surface of the top component 211. In addition, when the top component 211 is not provided with a fixing point, and a fixing point is provided on a lower-level component of the top component 211, the pressing plate 450 can be disposed on the top component 211 or above the fixing point of the lower-level component, and this application does not limit this.

[0137] Based on the above technical solution, it is possible to effectively prevent the wire harness 130 from running around in the storage portion 410 during compression, overflowing the storage portion 410 , and causing the wire harness 130 to become tangled with other components.

[0138] As shown in (a), (b) and (c) in Figure 11, the multi-stage telescopic member 210 is stretched to its longest state, and the wiring harness 130 between each fixed point should be in a relaxed state. As shown in (d), (e) and (f) in Figure 11, the multi-stage telescopic member 210 is compressed to its shortest state, and the wiring harness 130 is stacked in the storage portion 410 due to the constraints of the fixed point, or the fixed point and the pressure plate 450, and will not overflow from the storage portion 410.

[0139] In one embodiment, the storage portion 410 can be integrally formed with the slide rail of the mobile device 110. Based on this technical solution, the storage portion 410 is made part of the slide rail, which saves space occupied by the device.

[0140] The wiring harness 130 mentioned in the above embodiment of the present application can be not only an ordinary wiring harness and a drag chain wiring harness, but also a flat wiring harness. Since the flat wiring harness itself is easy to bend and can be easily stacked after bending, the flat wiring harness is not prone to the problem of itself getting entangled and knotted during the movement of the mobile device 110, nor is it prone to the problem of getting entangled and knotted with other components.

[0141] The embodiment of the present application further provides a vehicle door, comprising any one of the fixing device 200 and the moving device 110 provided in the embodiment of the present application.

[0142] In some possible embodiments, the movable device 110 included in the vehicle door is a liftable door glass, which is connected to the fixing device 200 . The liftable door glass is connected to the fixing device 200 via an elastic connector 270 .

[0143] An embodiment of the present application further provides a vehicle, comprising any one of the fixing devices 200 provided in the above embodiments, or comprising the above vehicle door.

[0144] An embodiment of the present application further provides a device, comprising any one of the fixing devices 200 , the mobile device 110 , and the power supply device 120 provided in the embodiment of the present application.
