Description

Technical Field

[0001] This application relates to the field of machinery, and more specifically, to fastening devices, vehicle doors, vehicles, and devices.

Background Art

[0002] With the development of science and technology, more functions, such as light-emitting and color-changing functions, touch functions, etc., have been imparted to conventional objects such as glass doors and glass windows. In order to implement the functions, the glass needs to be continuously powered through a harness. However, in application scenarios such as intelligent vehicles, the glass usually needs to perform ascending / descending operations. Throughout the ascending / descending process, one end of the harness is connected to the glass component through a connecting member, and the harness is stretched or contracted as the glass moves. In addition, during the process of stretching or contracting the harness, the harness gets entangled with another element for ascending / descending the glass, and during the ascending / descending process with the glass, the harness sways and repeatedly collides with another element, resulting in abnormal noises. In addition, the above-mentioned problems also exist in application scenarios where power is supplied to liftable screens of devices such as smart home devices or smartphones through a harness.

[0003] Therefore, in the process of supplying power to movable devices such as lifting glass or lifting screens, methods for improving the durability of the fastening of the harness and the movable device, methods for avoiding entanglement between the harness and other elements, and methods for avoiding abnormal noises caused by repeated collisions between the harness and other elements are urgent problems.

Summary of the Invention

[0004] The present application provides a fastening device, a vehicle door, a vehicle, and a device for fastening a harness to a multi-stage telescopic member via at least one fastening point, so that at least one fastening point shares the bearing force on the harness. The multi-stage telescopic member is connected to a movable device, whereby the durability of fastening the harness and the movable device can be improved, and the entanglement between the harness and another element and the abnormal noise caused by the repeated interference between the harness and another element can be effectively avoided.

Means for Solving the Problems

[0005] According to a first aspect, there is provided a fastening device, the fastening device comprising: a multi-stage telescopic member, the multi-stage telescopic member including a plurality of components sequentially sleeved and slidable, the component located at the upper part being an upper component, the upper component being configured to be connected to a movable device, whereby the multi-stage telescopic member is extended or contracted as the movable device moves; and at least one fastening point, the at least one fastening point being disposed on the multi-stage telescopic member and configured to fasten a harness, one end of the harness being configured to be connected to the movable device and the other end of the harness being configured to be connected to a power supply device, whereby the power supply device supplies power to the movable device via the harness.

[0006] For example, the movable device is a power-consuming device, and the power supply device needs to be connected to the movable device via a harness to continuously supply power to the movable device. During the movement of the movable device, the harness also extends or contracts accordingly.

[0007] For example, one end of the harness may be directly connected to the movable device, or may be connected to the movable device via a connecting member. Alternatively, one end of the harness includes a lead head and is connected to the movable device via the lead head. The harness or the lead head of the harness may be connected to the connecting member of the movable device. Further, the harness or the lead head of the harness may be hermetically connected to the connecting member, thereby further improving the durability of fastening the harness and the movable device. Similarly, the other end of the harness may be directly connected to the power supply device. Alternatively, the other end of the harness includes a lead head and is connected to the power supply device via the lead head. Further, the other end of the harness or the lead head of the other end of the harness may be hermetically connected to the power supply device, whereby the power supply device supplies power to the movable device via the harness.

[0008] For example, when the multi-stage telescopic member is extended so as to be the longest, the multi-stage telescopic member may have a narrow bottom and a wide top as a whole. Or, when the multi-stage telescopic member is extended to the longest, the multi-stage telescopic member may have a narrow top and a wide bottom as a whole.

[0009] For example, the component located at the bottom is a bottom component, and the bottom component and the support base may or may not be fixedly connected, that is, they may be virtually connected.

[0010] For example, the harness may be fastened to the fastening point using a fastener, or may be fastened using a bundling strap, or may be fastened by welding or direct adhesive bonding.

[0011] Based on the foregoing technical solution, the fastening point supports a part of the weight of the harness, preventing the connecting member between the harness and the movable device from bearing the weight of the entire harness, thereby improving the durability of the connection between the harness and the movable device. In addition, the harness is fastened using the fastening point, and this fastening point limits the movement range of the harness during the process of the harness moving with the movable device.

[0012] Referring to the first aspect, in some implementations of the first aspect, the component located at the bottom is the bottom component, the bottom component is connected to the support base, the fastening device further includes a rotating shaft, the rotating shaft is disposed between the bottom component and the support base, whereby the multi-stage telescopic member rotates along the axis of the rotating shaft.

[0013] For example, the rotating shaft may be a rotating rod or a pivot rotating shaft.

[0014] Based on the above technical solution, the rotating shaft is disposed between the multi-stage telescopic member and the support base, whereby the multi-stage telescopic member automatically adjusts the angle of the multi-stage telescopic member in the process of the movable device moving along the curve, ensuring that the movable device can move normally along the non-linear track, and avoiding the case where the movable device stacks when moving along the curve and the multi-stage telescopic member is even damaged.

[0015] Referring to the first aspect, in some implementations of the first aspect, the fastening device is an elastic connection member, the elastic connection member is disposed between the upper component and the movable device, whereby the multi-stage telescopic member further includes an elastic connection member that can be pulled so as to be extended or contracted when the movable device moves.

[0016] For example, when the movable device moves along a curve, even if there is no rotating shaft for adjusting the angle of the multi-stage telescopic member, since the connection member between the upper component and the movable device is elastic, the force in the tangential direction of the curved movement track, which belongs to the movable device, can be decomposed into forces in directions parallel to the direction of the multi-stage telescopic member, whereby the multi-stage telescopic member can still be pulled so as to be extended or contracted.

[0017] Based on the above technical solution, the upper component of the multi-stage telescopic device is connected to the movable device via an elastic connection member. Thereby, in the process of the movable device moving along a curve, a force in a direction parallel to the direction of the multi-stage telescopic member can be obtained by decomposition through the elastic connection member. The multi-stage telescopic member ensures that the movable device can move normally along the curve, and when the movable device moves along a non-linear track, the movable device will not stack up, and the multi-stage telescopic member can still be stretched to avoid being damaged even when it is extended or contracted.

[0018] Referring to the first aspect, in some implementation forms of the first aspect, the number of at least one fastening point is the same as the number of components included in the multi-stage telescopic member, and one fastening point is arranged at each stage of the component.

[0019] Based on the above technical solution, the fastening points of all stages of the component support the weight of the entire harness together. This further improves the durability of the connection between the harness and the movable device. In addition, the harness is fastened using a plurality of fastening points, and these fastening points also limit the movement range of the harness in the process of the harness moving with the movable device.

[0020] Referring to the first aspect, in some implementation forms of the first aspect, the component has a hollow structure and is configured to accommodate the harness.

[0021] Based on the above technical solution, the multi-stage telescopic member has a hollow structure and is configured to accommodate the harness, thereby further limiting the movement range of the harness. This effectively avoids the entanglement between the harness and other elements, and also avoids the abnormal noise caused by the interference between the harness and other elements.

[0022] Referring to the first aspect, in some implementations of the first aspect, the fastening device further includes a first hole provided on the upper component and configured to draw out one end of the harness, and a second hole provided on the bottom component and configured to draw out the other end of the harness.

[0023] Based on the above technical solution, a closed space is provided for the harness and used to accommodate the harness. The first hole and the second hole are provided on the multi-stage telescopic member, whereby the harness is separately connected to the movable device and the power supply device to continuously supply power to the movable device.

[0024] Referring to the first aspect, in some implementations of the first aspect, at least one fastening point includes a first fastening point and a second fastening point. The first fastening point is arranged on the upper component, and the second fastening point is arranged on the bottom component. When the multi-stage telescopic member is contracted to its shortest length, the harness between the first fastening point and the second fastening point is distributed in a U-shape.

[0025] Based on this technical solution, since the harnesses are not stacked together inside the bottom component, the case where the harnesses are entangled alone can be effectively prevented.

[0026] Referring to the first aspect, in some implementations of the first aspect, the harness is a drag chain harness.

[0027] Based on the above technical solution, the drag chain harness has good stability and high durability characteristics. The weight of the drag chain can also play a role in restricting the harness, whereby the harness is less likely to become entangled by itself.

[0028] Referring to the first aspect, in some implementations of the first aspect, a first opening is provided on the surface of the component.

[0029] For example, the surface of the component may be a large surface of the component, where the large surface is the surface having the largest area among the surfaces of the component, or it may be another surface. Due to the limiting function of the drag chain harness, usually, even if the first opening is provided on the surface of the component, the drag chain harness will not protrude from the first opening during the process of extending or contracting the drag chain harness.

[0030] Based on the above-mentioned technical solution, since the drag chain harness has the characteristic of restricting the harness, the drag chain harness is less likely to become entangled with other elements due to protruding from the first opening on the surface of the component. Furthermore, the multi-stage telescopic member is lightweight to a certain extent, thereby reducing the weight of the fastening device and the manufacturing cost.

[0031] Referring to the first aspect, in some implementation forms of the first aspect, the component is a baffle plate, and the fastening device is a receiving portion, where one side of the receiving portion has a second opening, the second opening is disposed opposite to the multi-stage telescopic member, and when the multi-stage telescopic member is extended to its longest length, the range of the second opening covers all of at least one fastening point disposed on the multi-stage telescopic member, and further includes the receiving portion.

[0032] For example, the receiving portion may have a box-shaped structure, for example, it may be a harness box having a second opening on one side.

[0033] For example, the side having the second opening may be a large surface of the receiving portion, or it may be a side surface of the receiving portion. The side surface is a surface other than the upper end surface or the lower end surface of the receiving portion that is connected to the large surface.

[0034] Based on the above technical solution, the accommodating part is configured to accommodate the harness fastened to the multi-stage telescopic member in order to further limit the movement range of the harness when the harness moves with the movable device. This can effectively avoid the entanglement between the harness and other elements, and can also avoid the abnormal noise caused by the interference between the harness and other elements.

[0035] Referring to the first aspect, in some implementations of the first aspect, the lower end of the second opening is connected to the bottom component, and the fastening device includes a third hole provided at the upper end of the accommodating part or the upper component and configured to draw out one end of the harness, and a fourth hole provided at the lower end of the accommodating part or the bottom component and configured to draw out the other end of the harness.

[0036] Based on the above technical solution, a closed space is provided for the harness and used to accommodate the harness. The third hole and the fourth hole are provided on the multi-stage telescopic member or the accommodating part, whereby the harness is separately connected to the movable device and the power supply device to continuously supply power to the movable device.

[0037] Referring to the first aspect, in some implementations of the first aspect, the fastening device includes a pressure plate disposed on the upper component and extending to the inside of the accommodating part to prevent the harness from protruding from the second opening during the process of contracting the multi-stage telescopic member.

[0038] For example, when the fastening point is disposed on the upper component, the pressure plate may be disposed above the fastening point of the upper component. Alternatively, the pressure plate may be directly disposed on the upper end surface of the upper component. For example, when the fastening point is not disposed on the upper component and the fastening point is disposed on the component at the lower stage of the upper component, the pressure plate may be disposed on the upper component, or the pressure plate may be disposed above the fastening point of the lower-stage component.

[0039] Based on the above technical solution, in the contraction process, the phenomenon that the harness fails inside the accommodation part and protrudes from the accommodation part, resulting in entanglement between the harness and another element, can be effectively prevented.

[0040] Referring to the first aspect, in some implementations of the first aspect, the accommodation part of the movable device and the slide rail are integrally formed.

[0041] Based on the above technical solution, the accommodation part is used as a part of the slide rail, saving the space occupied by the device.

[0042] Referring to the first aspect, in some implementations of the first aspect, the harness is a flat harness.

[0043] Based on the above technical solution, this is because the flat harness is easy to bend and is likely to be stacked on top of each other after being bent. Therefore, the flat harness is used to effectively avoid the problem that the harness gets entangled with itself during the movement process with the movable device, and can also avoid the problem that the harness gets entangled with another element.

[0044] According to the second aspect, a vehicle door is provided, and the vehicle door includes a fastening device and a movable device according to any one of the possible implementations of the first aspect.

[0045] Referring to the second aspect, in some implementations of the second aspect, the movable device included in the vehicle door is a liftable vehicle door glass, and the liftable vehicle door glass is connected to the fastening device.

[0046] Referring to the second aspect, in some implementations of the second aspect, the liftable vehicle door glass is connected to the fastening device via an elastic connection member.

[0047] According to a third aspect, a vehicle is provided, the vehicle including a fastening device according to any one of the possible implementation forms of the first aspect, or a vehicle door according to any one of the possible implementation forms of the second aspect.

[0048] According to a fourth aspect, a device is provided, the device including a fastening device according to any one of the possible implementation forms of the first aspect.

[0049] For example, the device may be a display, a television, a curtain, a building glass, or a roof skylight, etc.

Embodiments for Carrying Out the Invention

[0051] The following is an explanation of the technical solution of the present application with reference to the accompanying drawings.

[0052] The fastening device 200 provided in the present application is applicable to a vehicle and is used together with the lifting glass of the vehicle. The vehicle in the present application (which may also be abbreviated as a car) is a generalized concept of a vehicle, including transportation means (e.g., automobiles, trucks, motorcycles, trains, airplanes, or ships), industrial vehicles (e.g., forklift trucks, trailers, or tractors), engineering vehicles (e.g., hydraulic excavators, bulldozers, or cranes), agricultural devices (e.g., lawn mowers, harvesters), recreational devices, toy vehicles, etc. The type of vehicle is not limited in the present application. In addition, the fastening device 200 provided in the present application is applicable to a scenario where the fastening device 200 extends or contracts as another power supply object moves.

[0053] For example, in a scenario where the vehicle door glass of a vehicle is powered, the vehicle door glass needs to be continuously powered in order to implement functions such as electrochromism and touch of the vehicle door glass. FIG. 1 is a diagram showing continuous power supply to the movable device 110 according to an embodiment of the present application. Usually, the power supply device 120 of the vehicle is connected to the movable device 110 via the harness 130. The power supply device 120 may be the battery of the vehicle or a separately configured battery device for powering the movable device 110. This is not limited in the embodiments of the present application. The movable device 110 may be the vehicle door glass of the vehicle. Further, the harness 130 may be connected to the movable device 110 via the connection member 140. When the movable device 110 rises, the harness 130 is extended as the movable device 110 rises, and when the movable device 110 descends, the harness 130 is contracted as the movable device 110 descends. However, in the process of rising / falling of the movable device 110, there are the following problems.

[0054] (1) Entanglement problem: After the movable device 110 descends, during the process of contracting the harness 130, the bent part of the harness 130 becomes entangled with accessories of the vehicle door sheet metal, such as a glass lifting slide rail and a door reinforcement beam, restricting the harness 130. Subsequently, when the movable device 110 ascends, the harness 130 may break.

[0055] (2) Durability problem: During the ascending / descending process of the movable device 110, the connecting member 140 between the harness 130 and the movable device 110 needs to support the weight of the harness 130. Especially when the movable device 110 ascends to the limit, this fastening point may need to support the weight of the entire harness 130. Therefore, during the process of repeatedly raising and lowering the vehicle door glass, the durability of the connection between the harness 130 and the connecting member 140 cannot be guaranteed.

[0056] (3) Problem of controlling abnormal noise caused when the harness 130 is suspended and swinging: During the ascending / descending process of the movable device 110, the harness 130 swings and collides with the surrounding components of the harness 130, resulting in the generation of abnormal noise.

[0057] The foregoing has described, as an example, a scenario in which the vehicle door glass of a vehicle is powered, and has explained the current problems in that scenario. Similarly, there are problems in another application scenario where the movable device 110 needs to be continuously powered via the harness 130, for example, in the scenario of the raising / lowering of a robotic arm. However, all existing technical solutions have defects such as complex processes, difficult mass production, and insufficient durability. Considering this, the present application provides a fastening device 200. By using the multi-stage telescopic member 210, in the process of the harness 130 moving together with the movable device 110, the problem of entanglement between the harness 130 and other elements is avoided, and a plurality of fastening points for fastening the harness 130 are arranged on the multi-stage telescopic member 210 to share the supporting force for the harness 130. This improves the durability of the connection between the harness 130 and the movable device 110. In addition, the device 200 for restricting the harness 130 can more effectively avoid the abnormal noise caused by the repeated butting between the harness 130 and other elements.

[0058] In one embodiment of the present application, an application scenario in which the movable device 110 is continuously powered via the harness 130 is used to explain the device 200 for restricting the harness 130 provided in the embodiment of the present application.

[0059] FIGS. 2(a) to 2(c) are diagrams of the structure of the fastening device 200 according to an embodiment of the present application. FIGS. 2(a) to 2(c) are side cross-sectional views of the fastening device 200. FIG. 2(a) is a diagram of the structure obtained when the fastening device 200 is extended to be the longest as the movable device 110 moves. FIG. 2(b) is a diagram of the structure obtained when the fastening device 200 is contracted to be the shortest as the movable device 110 moves. FIG. 2(c) is a diagram for arranging the fastening points when the harness 130 is excessively long.

[0060] The device 200 is A multi-stage telescopic member 210, wherein the multi-stage telescopic member 210 includes a plurality of components with sleeves that can slide sequentially, and the component located at the upper part is the upper component 211, and the upper component 211 is configured to be connected to the movable device 110, whereby the multi-stage telescopic member 210 is extended or contracted as the movable device 110 moves, the multi-stage telescopic member 210, At least one fastening point 220, wherein the at least one fastening point 220 is arranged on the multi-stage telescopic member 210 and is configured to fasten the harness 130, one end of the harness 130 is configured to be connected to the movable device 110, and the other end of the harness 130 is configured to be connected to the power supply device 120, whereby the power supply device 120 supplies power to the movable device 110 via the harness 130, at least one fastening point 220 and comprises.

[0061] The upper component 211 is a component located at the upper part of the entire multi-stage telescopic member 210 when the multi-stage telescopic member 210 is extended to be the longest along the direction perpendicular to the ground.

[0062] In one embodiment, the movable device 110 is a power-consuming device, and the power supply device 120 needs to be connected to the movable device via the harness 130 to continuously supply power to the movable device 110. During the movement process of the movable device 110, the harness 130 is also extended or contracted accordingly.

[0063] In some possible embodiments, one end of the harness 130 may be directly connected to the movable device 110, for example, may be connected to the movable device 110 via a connecting member. Alternatively, one end of the harness 130 may include a lead head and is connected to the movable device 110 via the lead head. The harness 130 or the lead head of the harness 130 may be connected to the connecting member 140 of the movable device 110. Further, the harness 130 or the lead head of the harness 130 may be hermetically connected to the connecting member 140, whereby the durability of the connection between the harness 130 and the movable device 110 is further improved. Similarly, the other end of the harness 130 may be directly connected to the power supply device 120. Alternatively, the other end of the harness 130 includes a lead head and is connected to the power supply device 120 via the lead head. Further, the other end of the harness 130 or the lead head of the other end of the harness 130 may be hermetically connected to the power supply device 120, whereby the power supply device 120 supplies power to the movable device 110 via the harness 130.

[0064] In some possible embodiments, the multi-stage telescopic member 210 includes N-stage components sequentially sleeved so as to be slidable. The width of the i-th stage component is larger than the width of the (i - 1)-th stage component, that is, when the multi-stage telescopic member 210 is extended to be the longest, the multi-stage telescopic member 210 is narrower at the bottom and wider at the top as a whole. Alternatively, the width of the i-th stage component of the multi-stage telescopic member 210 may be smaller than the width of the (i - 1)-th stage component, that is, when the multi-stage telescopic member 210 is extended to be the longest, the multi-stage telescopic member 210 is narrower at the top and wider at the bottom as a whole. This is not limited in the embodiments of the present application. In this specification, i is a positive integer greater than 1 and less than or equal to N.

[0065] For ease of explanation, the following uses, for illustrative purposes, an example in which the movable device 110 is the lifting glass of a vehicle door. The bottom component 212 of the fastening device 200 may be connected to a support base, and the support base may be a vehicle door sheet metal.

[0066] As shown in FIG. 2(a), in one embodiment, the multi-stage telescopic member 210 includes N components with sleeves that can slide sequentially, where N is a positive integer greater than 1. During the process of the lifting glass ascending, since the upper end of the Nth component of the multi-stage telescopic member 210 is connected to the lifting glass, the Nth component is first pulled up by the lifting glass. When the Nth component is pulled up to its highest position, because the components are sequentially sleeved and can slide, the Nth component pulls up the (N - 1)th component, thereby causing the entire multi-stage telescopic member 210 to continue to extend. The same process is executed until the lifting glass ascends to its highest position. In this case, the multi-stage telescopic member 210 may be extended to its longest length. The Nth component is the upper component 211. The upper component 211 may be directly connected to the lifting glass or may be connected to the slider 111 of the lifting glass shown in FIG. 2(c). The slider is arranged on the glass slide rail and fastened to the glass to drive the glass to ascend / descend. Of course, specifically, the upper component 211 may be connected to the lifting glass by bonding, or if the upper component 211 is connected to the lifting glass, it may also be connected to the lifting glass through another connecting member. This is not limited in the embodiments of the present application.

[0067] In contrast, as shown in Fig. 2(b), in the process of the lifting glass descending, from the second-stage component to the N-stage component, as a whole, they descend together with the lifting glass. When the second-stage component first descends to the lowest position, since the component is sequentially sleeved slidably, from the third-stage component to the N-stage component, they continue to descend as a whole together with the lifting glass. The same process is executed until the lifting glass descends to the lowest position. In this case, the multi-stage telescopic member 210 may be contracted to be the shortest, and each component of the multi-stage telescopic member 210 is accommodated by the upper or lower component. Since the bottom component 212 is fixedly connected to the vehicle door sheet metal, the bottom component 212 is not lifted during the ascending / descending process of the lifting glass.

[0068] In the foregoing embodiment, the bottom component 212 and the vehicle door sheet metal are fixedly connected. In some other possible embodiments, the bottom component 212 and the vehicle door sheet metal may not be fixedly connected, that is, they may be virtually connected. This is also applicable to the foregoing technical solution. Similarly, the bottom component 212 is not necessarily fixedly connected to the vehicle door sheet metal. Alternatively, the stages of the components other than the upper component 211 may be fixedly connected to the vehicle door sheet metal. This is not limited in the embodiments of the present application.

[0069] In some possible embodiments, in the process of the lifting glass ascending continuously, when the i-stage component is lifted to the highest position, the (i - 1)-stage component needs to be lifted via a connecting member. The connecting member can be shown in Fig. 3. Fig. 3 is a diagram of the structure of another fastening device 200 according to an embodiment of the present application. Fig. 3 is a front view of the fastening device 200.

[0070] In the example shown in FIG. 3, i is equal to N, and the connecting member includes a slide rail 230 and a fastening button 240. The fastening button 240 may be disposed at the lower end of the component in the i-th stage, and the slide rail 230 may be disposed on the component in the (i - 1)-th stage. The slide rail 230 is a linear slide rail and is parallel to the extension / expansion direction of the multi-stage telescopic member 210. The slide rail 230 may extend from the upper end to the lower end of the component in the (i - 1)-th stage, or from the upper end to the middle part of the component in the (i - 1)-th stage. The protrusion on the component in the (i - 1)-th stage, which belongs to the fastening button 240, is in a straight line with the slide rail.

[0071] In addition, the connecting member may be shown in FIG. 4. FIG. 4 is a diagram of the structure of another fastening device 200 according to an embodiment of the present application. FIG. 4 is a front view of the fastening device 200.

[0072] In the example shown in FIG. 4, i is equal to N, and this connection structure includes a first wrapping member 251 and a second wrapping member 252. The first wrapping member 251 is disposed at the lower end of the component in the i-th stage, and the second wrapping member 252 is disposed at the upper end of the component in the (i - 1)-th stage. In addition, the connection structure provided in the present application may be in another form. This is not limited in the present application.

[0073] In some possible embodiments, the connecting member between the component in the i-th stage and the component in the (i - 1)-th stage may be disposed below the fastening point of the component in the (i - 1)-th stage. In this way, when the multi-stage telescopic member 210 is contracted to be the shortest, the harness 130 is not clamped between the layers of the components. Alternatively, FIG. 5 is a diagram of the structure of another fastening device 200 according to an embodiment of the present application. FIG. 5 is a front view of the fastening device 200. The fastening point is disposed within the edge region on the side surface of each stage of the component, and the edge region is not the overlapping region of the component that occurs when each stage of the component is accommodated by the upper stage or the lower stage of the component. This structure can also prevent the harness 130 from being clamped between the layers of the components.

[0074] In some possible embodiments, the harness 130 may be fastened to the fastening point using a fastener, or the harness 130 may be fastened using a bundling strap, or the harness 130 may be fastened by welding or a direct adhesive bonding method. The specific method of fastening the harness 130 to the fastening point is not limited in the embodiments of this application.

[0075] Based on the foregoing technical solutions, the device provided in this embodiment of this application includes a fastening point, and the fastening point can support a part of the weight of the harness 130 to prevent the connecting member between the harness 130 and the door lifting glass from supporting the entire weight of the harness 130. This improves the durability of the connection between the lead of the harness 130 and the movable device 110. In addition, the harness 130 is fastened using a fastening point, and this fastening point limits the movement range of the harness 130 during the process of the harness 130 moving with the movable device 110.

[0076] In some possible embodiments, each stage of the components of the multi-stage telescopic member 210 is provided with one fastening point described above. In addition, as shown in FIG. 2(c), when the harness 130 is overly long, a plurality of the fastening points described above may be further arranged on the stages of the components, and the harness 130 is bent to an appropriate length using the fastening points.

[0077] In some possible embodiments, during the process of extending the multi-stage telescopic member 210 to its longest length, the harness 130 between the fastening points is always in a loose state.

[0078] Based on the foregoing technical solutions, the fastening points of all stages of the components support the entire weight of the harness 130 together. This further improves the durability of the connection between the harness 130 and the movable device 110. In addition, the harness 130 is fastened using a plurality of fastening points, and these fastening points also limit the movement range of the harness 130 during the process of the harness 130 moving with the movable device 110.

[0079] FIG. 6 is a diagram of the structure of the fastening device 200 according to an embodiment of the present application.

[0080] The device includes a rotating shaft 260, which is disposed between the outer surface of the bottom component 212 and the support base 150 to connect the bottom component 212 and the support base 150, and enables the multi-stage telescopic member 210 to rotate along the shaft of the rotating shaft 260.

[0081] Similar to the upper component 211 located at the upper part, the component located at the bottom is the component located at the bottom of the entire multi-stage telescopic member 210 when the multi-stage telescopic member 210 is extended so as to be the longest along the direction perpendicular to the ground.

[0082] For example, the movable device 110 is a vehicle door lifting glass. Since the housing of most vehicles is set in a streamlined shape, the rising / falling track of the vehicle door lifting glass is curved. When the multi-stage telescopic member 210 is directly and fixedly connected to the vehicle door sheet metal, it cannot be guaranteed that the multi-stage telescopic member 210 can rise and fall together with the lifting glass. As a result, the glass stacks up, and the multi-stage telescopic member 210 may even be damaged during the rising / falling process.

[0083] Therefore, the outer surface of the bottom component 212 is connected to the vehicle door sheet metal via the rotating shaft 260. The rotating shaft 260 may be a rotating rod or a pivot rotating shaft. This is not limited in the embodiments of the present application.

[0084] When the lifting glass rises along a curve while driving to raise the Nth-stage component, the lifting glass also rotates the rotating shaft 260 along the shaft axis to adjust the angle of the multi-stage telescopic member 210, thereby ensuring an effective rising / falling movement along the curve during the rising / falling process of the glass.

[0085] In some possible embodiments, when the movable device 110 is a power-consuming device other than the lifting glass, the movable device 110 may move along an irregular orbit. The technical solutions provided in the foregoing embodiments are also applicable to this case.

[0086] Based on the above technical solution, the rotating shaft 260 is disposed between the multi-stage telescopic member 210 and the support base 150 to ensure that in the process of the movable device 110 moving along a non-linear orbit, the multi-stage telescopic member 210 can automatically adjust the angle of the multi-stage telescopic member 210, thereby ensuring that the movable device 110 can move normally along the non-linear orbit, and avoiding the case where the movable device 110 stacks up and the multi-stage telescopic member 210 is even damaged when the movable device 110 moves along a curve.

[0087] FIG. 7 is a diagram of the structure of another fastening device 200 according to an embodiment of the present application.

[0088] The fastening device 200 may further include an elastic connection member 270, where the elastic connection member 270 is disposed between the upper component 211 and the movable device 110, so that when the movable device 110 moves along a curve, the multi-stage telescopic member 210 can still be pulled to be extended or contracted. This embodiment is also applicable to the case where the rotating shaft 260 is not disposed between the bottom component 212 of the multi-stage telescopic member 210 and the support base 150.

[0089] For example, when the movable device 110 moves along a curve, even if there is no rotating shaft 260 for adjusting the angle of the multi-stage telescopic member 210, since the connection member between the upper component 211 and the movable device 110 is elastic, the force F in the tangential direction of the curved movement orbit, which belongs to the movable device 110, can be decomposed into a force in a direction parallel to the direction of the multi-stage telescopic member 210 and a force F1, so that the multi-stage telescopic member 210 can still be pulled by the movable device 110 to be extended or contracted.

[0090] In some possible embodiments, when the movable device 110 is a power-consuming device other than the lifting glass, the movable device 110 may move along an irregular track. The technical solutions provided in the foregoing embodiments are also applicable to this case. Of course, the technical solutions provided in this embodiment are also applicable to the case where the rotating shaft 260 is disposed between the bottom component 212 and the support base 150.

[0091] Based on the foregoing technical solutions, the upper component 211 of the multi-stage telescopic device is connected to the movable device 110 via the elastic connection member 270. In the process of the movable device 110 moving along the non-linear track, a force F1 in a direction parallel to the direction of the multi-stage telescopic member 210 can be obtained through decomposition via the elastic connection member 270, so as to ensure that the multi-stage telescopic member 210 can still be pulled to be extended or contracted, thereby ensuring that the movable device 110 can move normally along the non-linear track, and avoiding the case where the movable device 110 stacks up when moving along the non-linear track and the multi-stage telescopic member 210 is even damaged.

[0092] FIG. 8 is a structural diagram of another fastening device 200 according to an embodiment of the present application. In this embodiment, each stage of the components of the multi-stage telescopic member 210 included in the fastening device 200 has a hollow structure. For example, the hollow structure may be a structure in the form of a harness box and is configured to accommodate the harness 130.

[0093] In some possible embodiments, when the multi-stage telescopic member 210 includes two components sleeved slidably in sequence, since the upper component 211 and the bottom component 212 are sleeved slidably, the lower end surface of the upper component 211 and the upper end surface of the bottom component 212 are both not closed. Thereby, the harness 130 can be arranged through all stages of the components of the multi-stage telescopic member 210. FIG. 9 is a structural diagram of another fastening device 200 according to an embodiment of the present application. Alternatively, the upper end surface of the upper component 211 may not be closed. Thereby, one end of the harness 130 is drawn out, and one end of the harness 130 is connected to the movable device 110. Alternatively, of course, the upper end surface of the upper component 211 may be closed, and it is necessary to provide a first hole 310. Thereby, one end of the harness 130 is drawn out, and one end of the harness 130 is connected to the movable device 110 to better accommodate the harness 130. Since the bottom component 212 is in contact with the support base 150, regardless of whether the lower end surface of the bottom component 212 is closed or not, the harness 130 will not fall from the multi-stage telescopic member 210 in the contraction process. Therefore, in order to draw out the other end of the harness 130 so that the other end of the harness 130 is connected to the power supply device 120 to continuously supply power to the movable device 110, a second hole 320 needs to be provided on the bottom component 212.

[0094] For ease of explanation, when the multi-stage telescopic member 210 includes three or more components with sleeves slidably attached in series, in this embodiment of the present application, components other than the upper 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 includes a plurality of components with sleeves slidably attached in sequence, the upper and lower end surfaces of the intermediate components are not closed. As a result, the harness 130 can be arranged over all stages of the components of the entire multi-stage telescopic member 210. Alternatively, the upper end surface of the upper component 211 may not be closed, whereby one end of the harness 130 is drawn out and one end of the harness 130 is connected to the movable device 110. Alternatively, of course, the upper end surface of the upper component 211 may be closed, and in order to draw out one end of the harness 130 so that the end of the harness 130 is connected to the movable device 110, a first hole 310 needs to be provided. Since the bottom component 212 is in contact with the support base 150, regardless of whether the lower end surface of the bottom component 212 is closed, the harness 130 will not fall from the multi-stage telescopic member 210 during the contraction process. Therefore, in order to draw out the other end of the harness 130 so that the other end of the harness 130 is connected to the power supply device 120 to continuously supply power to the movable device 110, a second hole 320 needs to be provided on the bottom component 212.

[0095] Based on the above technical solution, the multi-stage telescopic member 210 has a hollow structure and is configured to accommodate the harness 130, thereby further restricting the movement range of the harness 130. This effectively avoids entanglement between the harness 130 and other elements and also avoids abnormal noises caused by interference between the harness 130 and other elements.

[0096] Figures 10(a) to 10(e) are diagrams of the structure of another fastening device 200 according to an embodiment of the present application. Figure 10(a) is a diagram of the structure obtained when the multi-stage telescopic member 210 is in the extension process. Figure 10(b) is a diagram of the structure obtained when the multi-stage telescopic member 210 is contracted to be the shortest. Figure 10(c) is a cross-sectional view of the first cross-section of (a). Figure 10(d) is a cross-sectional view of the second cross-section of (a). Figure 10(e) is a diagram of the form of the harness 130 arranged in the device shown in Figures 10(a) to 10(e). The multi-stage telescopic member 210 shown in Figures 10(a) to 10(e) includes two-stage components.

[0097] Based on the fastening device 200 provided in the foregoing embodiment, the harness 130 may be a drag chain harness, and the drag chain harness has good stability. The weight of the drag chain also plays a role in restricting the harness 130, whereby the harness 130 is less likely to become entangled by itself.

[0098] Therefore, the first opening 330 may be further arranged on the surface of each stage of the components provided in the foregoing embodiment. The surface may be a large surface of the component, and the large surface is the surface having the largest area among the surfaces of the component. Due to the restricting function of the drag chain harness, usually, even if the first opening is provided on the surface of the component, the drag chain harness will not protrude from the first opening during the process of extending or contracting the drag chain harness.

[0099] A cross-sectional view of the fastening device 200 presented in the first cross-section is shown in Fig. 10(c). The section of the part indicated by 1010 in the figure is a section along the first cross-section of the drag chain harness. The left section of the drag chain harness is a section of one end of the drag chain harness fastened to the upper component 211, and the right section of the drag chain harness is a section of the other end of the drag chain harness fastened to the bottom component 212. In addition, a cross-sectional view of the fastening device 200 in the second cross-section is shown in Fig. 10(d). The section of the part indicated by 1010 in the figure is a section along the second cross-section of the drag chain harness. However, in the second cross-section, since the other end of the drag chain harness fastened to the bottom component 212 is not cut off, only the section of one end of the drag chain harness fastened to the upper component 211 is presented in the figure. In addition, it can be seen from Fig. 10(c) and Fig. 10(d) that the first openings 330 arranged in all stages of the components may be arranged on the surfaces in the same direction or, of course, may be arranged on the surfaces in alternating directions. This is not limited in the present application.

[0100] Based on the above technical solution, since the drag chain harness has the characteristic of restricting the harness, the drag chain harness is less likely to get entangled with other elements due to protruding from the first opening 330 on the surface. Furthermore, the multi-stage telescopic member 210 is lightweight to some extent, whereby the fastening device 200 is lightened and the manufacturing cost is reduced.

[0101] In some possible embodiments, at least one fastening point 220 includes a first fastening point 221 and a second fastening point 222. The first fastening point 221 may be disposed on the upper portion of the upper component 211, and the second fastening point 222 may be disposed on the upper portion of the bottom component 212. When the multi-stage telescopic member 210 is contracted so as to be the shortest, the first fastening point 221 and the second fastening point 222 may be located in a space on the same plane perpendicular to the extension / retraction direction of the multi-stage telescopic member 210. In this case, the drag chain harness is fastened by two fastening points. Therefore, the length of the drag chain harness can be adjusted so that the drag chain harness can be distributed in a U shape.

[0102] Based on this technical solution, since the drag chain harnesses are not stacked together within the bottom component 212, the case where the harness 130 gets entangled alone can be effectively prevented.

[0103] Based on the fastening device 200 provided in the above embodiment, when the harness 130 is excessively long, a drag chain may be added to the harness 130 of an appropriate length. That is, the length of the harness 130 for which it is necessary to add a drag chain is determined based on the moving distance of the movable device 110 connected to the harness 130. As shown in FIG. 10(e), the drag chain is added to a part of the harness 130. Under the fastening functions of the first fastening point 221 and the second fastening point 222, and under the self-weight effect of the drag chain, this part of the harness 130 is freely suspended by the drag chain. The left figure shows the state of the drag chain harness in the fastening device 200 when the harness 130 is in a stretched state, and the right figure shows that the drag chain harness is in a U-shaped distribution state as a whole when it is contracted so that the multi-stage telescopic member 210 is the shortest. Regarding the redundant part of the harness 130, from FIGS. 10(c) and 10(d), a harness groove 1020 may be further provided under the second fastening point 222 of the bottom component 212. The harness groove is connected to the second hole 320 of the bottom component 212. Thereby, it can be seen that the redundant harness 130 can be accommodated in the harness groove and is connected to the power supply device 120 through the second hole 320. Based on this technical solution, a case where the redundant harness 130 is entangled alone within the multi-stage telescopic member 210 can be effectively prevented.

[0104] In some possible embodiments, the bottom component 212 of the multi-stage telescopic member 210 is connected to the support base 150 via a rotating shaft 260, or the upper component 211 of the multi-stage telescopic member 210 is directly connected to the movable device 110 via an elastic connection member 270. Based on the technical solution, in order to prevent a case where the movable device 110 stacks up and the multi-stage telescopic member 210 is even damaged when the movable device 110 moves along a non-linear track, the multi-stage telescopic member 210 can still be extended or contracted when the movable device 110 moves along a curve.

[0105] Figs. 11(a) to 11(h) are diagrams of the structure of another fastening device 200 according to an embodiment of the present application. Fig. 11(a) is a structural diagram obtained when the multi-stage telescopic member 210 is extended to its longest length, and this structural diagram is a side cross-sectional view of the fastening device 200. Fig. 11(b) is a front view obtained when the multi-stage telescopic member 210 is extended to its longest length. Fig. 11(c) is a rear view obtained when the multi-stage telescopic member 210 is extended to its longest length. Fig. 11(b) is a diagram of the structure obtained when the multi-stage telescopic member 210 is extended to its shortest length. Fig. 11(d) is a diagram of the structure obtained when the multi-stage telescopic member 210 is contracted to its shortest length, and this structural diagram is a side cross-sectional view of the fastening device 200. Fig. 11(e) is a front view obtained when the multi-stage telescopic member 210 is contracted to its shortest length. Fig. 11(f) is a rear view obtained when the multi-stage telescopic member 210 is contracted to its shortest length. Fig. 11(g) is a diagram of the structure obtained when the multi-stage telescopic member 210 is not connected to the accommodating portion 410. Fig. 11(h) is a diagram of the structure of the fastening device 200 having a pressure plate 450 according to an embodiment of the present application.

[0106] Unlike the fastening device 200 shown in Figs. 10(a) to 10(e), each stage of the components of the multi-stage telescopic member 210 included in the fastening device 200 provided in this embodiment is a baffle plate. In addition, the device 200 includes an accommodating portion 410, one side of the accommodating portion 410 has a second opening 420, the second opening 420 is arranged opposite to the multi-stage telescopic member 210, and when the multi-stage telescopic member 210 is extended to its longest length, the range of the second opening 420 covers all the fastening points arranged on the multi-stage telescopic member 210.

[0107] In one embodiment, the accommodating portion 410 may have a box-shaped structure. For example, it may be a harness box having a second opening 420 on one side. The side having the second opening 420 may be a large surface of the accommodating portion 410 or a side surface of the accommodating portion 410. The side surface is a surface other than the upper end surface or the lower end surface of the accommodating portion 410 that is connected to the large surface.

[0108] Based on the above technical solution, the accommodating portion 410 is configured to accommodate the harness 130 fastened to the multi-stage telescopic member 210 in order to further limit the movement range of the harness 130 when the harness 130 moves together with the movable device 110. This can effectively avoid the entanglement between the harness 130 and other elements, and can also avoid the abnormal noise caused by the interference between the harness 130 and other elements.

[0109] In some possible embodiments, the accommodating portion 410 and the multi-stage telescopic member 210 may be fastened to the same support base 150, or the accommodating portion 410 may be fixedly connected to another base device, provided that the range of the second opening 420 covers all fastening points arranged on the multi-stage telescopic member 210 to prevent the harness 130 from stacking between the accommodating portion 410 and the multi-stage telescopic member 210 when the harness 130 is extended or contracted by the multi-stage telescopic member 210. Therefore, on the premise that the above conditions are satisfied, the height of the accommodating portion 410 may be greater than the height of the multi-stage telescopic member 210 when the multi-stage telescopic member 210 is extended to its longest length, or may be equal to the height of the multi-stage telescopic member 210 when the multi-stage telescopic member 210 is extended to its longest length, or may be smaller than the height of the multi-stage telescopic member 210 when the multi-stage telescopic member 210 is extended to its longest length.

[0110] In some possible embodiments, the multi-stage telescopic member 210 may be connected to the accommodating portion 410 via the rotating shaft 260, or the multi-stage telescopic member 210 may be connected to the support base 150 via the rotating shaft 260, or the upper component 211 of the multi-stage telescopic member 210 may be directly connected to the movable device 110 via the elastic connection member 270. Alternatively, the accommodating portion 410 and the multi-stage telescopic member 210 may be integrally formed. The integrally formed device may be connected to the support base 150 via the rotating shaft 260, or the upper component 211 of the multi-stage telescopic member 210 within the integrally formed device may be directly connected to the movable device 110 via the elastic connection member 270.

[0111] Based on the technical solution, in order to prevent the case where the movable device 110 stacks when the movable device 110 moves along the non-linear track and the multi-stage telescopic member 210 is even damaged, the multi-stage telescopic member 210 can still be extended or contracted when the movable device 110 moves along the curve.

[0112] In some possible embodiments, as shown in FIGS. 11(a) and 11(d), the fastening device 200 is a third hole 430, the third hole 430 is provided at the upper end of the accommodating portion 410 or the upper component 211, configured to draw out one end of the harness 130, and this one end can be connected to the movable device 110, the third hole 430; is a fourth hole 440, the fourth hole 440 is provided at the lower end of the accommodating portion 410 or the bottom component 212, configured to draw out the other end of the harness 130, and this end portion can be connected to the power supply device 120, the fourth hole 440 and further includes.

[0113] Based on the above-mentioned technical solution, the movable device 110 can be continuously powered.

[0114] In some possible embodiments, as shown in FIG. 11(g), when the accommodating portion 410 and the multi-stage telescopic member 210 are two independent devices from each other, the gap between the accommodating portion 410 and the multi-stage telescopic member 210 may be smaller than the diameter of the harness 130 and larger than the diameter of the leads drawn from the two ends of the harness 130, whereby the leads drawn from the two ends of the harness 130 can pass through the gap. In this way, the lead drawn from one end of the harness 130 is connected to the movable device 110, and the lead drawn from the other end of the harness 130 is connected to the power supply device 120.

[0115] Based on the above technical solution, the movable device 110 can also be continuously powered. Since the accommodating portion 410 and the multi-stage telescopic member 210 are two independent devices from each other, it is convenient for subsequent separate maintenance of the two devices, and there is no need to perforate holes in the fastening device 200, thereby simplifying the descending process of the fastening device 200.

[0116] FIG. 11(h) is a structural diagram of a fastening device 200 having a pressure plate 450 according to an embodiment of the present application. The fastening device 200 is a pressure plate 450, the pressure plate 450 is disposed on the upper component 211, and the pressure plate 450 extends to the inside of the accommodating portion 410 to prevent the harness 130 from protruding from the second opening 420 of the accommodating portion 410 during the contraction process of the multi-stage telescopic member 210, and further includes the pressure plate 450.

[0117] For example, when the fastening point is arranged on the upper component 211, the pressure plate 450 may be arranged above the fastening point of the upper component 211. Alternatively, the pressure plate 450 may be directly arranged on the upper end surface of the upper component 211. In addition, when the fastening point is not arranged on the upper component 211 and the fastening point is arranged on the component below the upper component 211, the pressure plate 450 may be arranged on the upper component 211, or the pressure plate 450 may be arranged above the fastening point of the component below it. This is not limited in this application.

[0118] Based on the above technical solution, the phenomenon that the harness 130 fails in the accommodating part 410 during the contraction process, protrudes from the accommodating part 410, and as a result, causes entanglement between the harness 130 and another element can be effectively prevented.

[0119] As shown in FIGS. 11(a), 11(b), and 11(c), in this case, the multi-stage telescopic member 210 is extended to be the longest, and the harness 130 between the fastening points should be in a loose state. As shown in FIGS. 11(d), 11(e), and 11(f), in this case, the multi-stage telescopic member 210 is contracted to be the shortest, and the harness 130 is stacked in the accommodating part 410 under the limitation of the fastening point or the fastening point and the pressure plate 450 and does not protrude from the accommodating part 410.

[0120] In one embodiment, the accommodating part 410 and the slide rail of the movable device 110 may be integrally formed. Based on the technical solution, the accommodating part 410 is used as a part of the slide rail, and the space occupied by the device is saved.

[0121] The harness 130 mentioned in the foregoing embodiments of this application may be a common harness, a drag chain harness, or a flat harness. Since the flat harness is easy to bend and is likely to be stacked on each other after bending, the flat harness is less likely to become entangled alone and is also less likely to become entangled with other elements during the process of moving together with the movable device 110.

[0122] Embodiments of the present application further provide a vehicle door including any fastening device 200 and movable device 110 provided in the embodiments of the present application.

[0123] In some possible embodiments, the movable device 110 included in the vehicle door is a liftable vehicle door glass, and the liftable vehicle door glass is connected to the fastening device 200. The liftable glass is connected to the fastening device 200 via an elastic connection member 270.
