Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to an electrical system and vehicle based on a door-module type window regulator. Background Technology

[0002] As automotive intelligence continues to advance, smart glass doors with functions such as dimming, heating, defrosting, and even projection displays are gradually becoming a key feature for enhancing the user experience. The realization of these functions relies on providing a continuous and stable power supply during the glass's operation.

[0003] In existing technologies, to power retractable glass, a common method is to connect one end of a wire to the vehicle's wiring harness and the other end directly to the glass. Because the glass needs to be raised and lowered frequently, the wire needs sufficient slack to accommodate its movement. However, this loose wiring arrangement has significant drawbacks: during vehicle movement or when the glass is raised or lowered, the unrestrained wire is prone to swinging freely within the door cavity, causing continuous impacts and scratches to the door panel, window regulator mechanism, or other internal components. This not only produces unpleasant noises, affecting cabin quietness and ride comfort, but over time can also lead to wear and tear on the wire insulation, fatigue fracture of the internal metal wires, causing the glass's electrical function to fail, and even posing a short-circuit risk.

[0004] Existing solutions, such as simple wire clips or partial sheaths, often only provide single-point fixation for the wires, failing to effectively control their entire movement. Interference may still occur in non-fixed sections. Other solutions are complex, space-consuming, and contradict the modular and compact design trend of automotive doors, while also hindering production, assembly, and subsequent maintenance. Therefore, there is an urgent need in this field for a systematic wire management solution integrated into the window regulator itself. This solution should ensure stable power supply while fundamentally regulating wire movement, eliminating the risk of abnormal noise and wear. Summary of the Invention

The drive mechanism is connected to the first glass bracket and the second glass bracket, and is used to drive the first glass bracket and the second glass bracket to move up and down along the guide rail to drive the door glass to move up and down.

[0012] In an optional embodiment, the drive mechanism includes a cable, a reel seat, and a motor; The winding reel seat is provided with a winding reel; The motor is mounted on the reel seat and is connected to the reel in a driving connection. One end of the cable is connected to the winding reel, and the other end passes around the guide wheel and is connected to the first glass bracket and the second glass bracket respectively. The motor drives the winding wheel to rotate, and the cable causes the first glass bracket and the second glass bracket to move up and down along the guide rail.

[0013] In an optional implementation, the cable is provided with three sections, namely a first section, a second section, and a third section; One end of the first segment is connected to the winding reel, and the other end is connected to the first glass bracket; One end of the second segment is connected to the first glass bracket, and the other end is connected to the second glass bracket; One end of the third segment is connected to the second glass bracket, and the other end is connected to the winding reel.

[0014] In an optional embodiment, a sealing strip is also included; The sealing strip is disposed between the door module body and the door sheet metal assembly.

[0015] Secondly, the present invention provides a vehicle including an energizing system based on a door module-type window regulator as described in any of the foregoing embodiments.

[0016] Compared with the prior art, the technical advantages of the power supply system and vehicle based on the door module type window regulator provided by the present invention are as follows: The present invention provides a power supply system based on a door module-type window regulator for use in vehicles. The power supply system based on the door module-type window regulator includes: a door module body, a wire assembly, and a wiring harness guiding mechanism; the door module body is fixed to the vehicle door sheet metal assembly; the wire assembly includes a wire, a first connector connected to one end of the wire, and a second connector connected to the other end of the wire, the first connector being connected to the vehicle door glass, and the second connector being connected to the vehicle door wiring harness; the wire assembly is used to continuously supply power to the door glass during the raising and lowering of the door glass; the wiring harness guiding mechanism is fixed to the door module body and is used to guide and constrain the direction and range of motion of the wire.

[0017] By electrically connecting the fixed door wiring harness to the moving door glass through a combination of wires, a complete power supply circuit is formed, ensuring that the door glass receives a continuous power supply at any lifting position.

[0027] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0028] The specific structure is as follows: Figures 1 to 8 As shown.

[0029] This embodiment provides a power supply system based on a door module-type window regulator for use in a vehicle. The power supply system based on the door module-type window regulator includes: a door module body 1, a wire assembly 8, and a wiring harness guiding mechanism. The door module body 1 is fixed to the vehicle's door sheet metal assembly. The wire assembly 8 includes a wire 82, a first connector 81 connected to one end of the wire 82, and a second connector 84 connected to the other end of the wire 82. The first connector 81 is connected to the vehicle's door glass, and the second connector 84 is connected to the vehicle's door wiring harness. The wire assembly 8 is used to continuously supply power to the door glass during the lifting and lowering of the door glass. The wiring harness guiding mechanism is fixed to the door module body 1 and is used to guide and constrain the direction and range of motion of the wire 82.

[0030] In this embodiment, the door module body 1 serves as an integrated installation platform, which can be fixed to the vehicle's door sheet metal assembly through various methods such as welding, bolting, or snap-fitting, forming the structural foundation of the entire system. Preferably, the door module body 1 is fixed to the door sheet metal assembly by the first snap-fit ​​10. The wire assembly 8 is the current transmission path of the system, where the wire 82 is typically a flexible multi-core cable. One end of the wire is connected to the corresponding interface on the door glass through the first connector 81 (e.g., a male or female connector), and the other end is connected to the vehicle's inherent door wiring harness through the second connector 84. Thus, regardless of whether the door glass is in an raised, lowered, or intermediate position, electrical energy can be continuously supplied to the door glass through the wire assembly 8 to support its electrical functions such as dimming and heating. The wiring harness guiding mechanism is fixed to the door module body 1. Its core function is not simply to fix the wire 82, but to actively guide and constrain the direction and range of motion of the wire 82. When the door window is raised or lowered, causing the wiring harness assembly 8 to move, the wiring harness guide mechanism forces the wire 82 to move along one or more preset paths and limits the amplitude of its lateral swing or radial sway.

[0031] In this embodiment, the fixed door wiring harness and the moving door glass are electrically connected by the wire assembly 8, forming a complete power supply circuit. This ensures that the door glass can obtain continuous power supply at any lifting position, laying a solid foundation for the realization of intelligent functions and achieving dynamic and stable power supply. The wire harness guide mechanism guides and constrains the wire 82 instead of passively fixing it, so that the wire 82 cannot deviate from the preset safety path during the entire movement. Its swing amplitude is strictly limited, thereby fundamentally avoiding collisions or scratches with other components, effectively eliminating abnormal noises and reducing the risk of wear and breakage of the wire 82 due to mechanical interference. At the same time, the wire harness guide mechanism is integrated into the door module body 1, forming a fully functional module. This modular design makes the entire power supply system compact and well-organized, improving the rigidity and stability of the overall system and making it easier for vehicle assembly and quality control.

[0032] In the optional technical solution of this embodiment, the wire harness guiding mechanism includes a wire harness cover 83 disposed on the door module body 1; the wire harness cover 83 is provided with a guiding structure 13 for the wire 82 to pass through.

[0033] In this embodiment, the wire harness plug 83 is fixed to the door module body 1 by snap-fit, screw-fit, or integral molding. The guide structure 13 can be a through hole, or a guide tube or guide groove with a specific radius of curvature. The wire 82 passes through the guide structure 13. The guide structure 13 on the wire harness plug 83 defines the initial direction of movement of the wire 82, ensuring that the wire 82 will not enter the dangerous area where interference may occur from the beginning, and limiting its movement within a safe starting channel. The structure is simple, reliable, and inexpensive.

[0034] In the optional technical solution of this embodiment, the wire harness guiding mechanism includes a limiting plate 7 disposed on the door module body 1; a movement space is formed between the limiting plate 7 and the door module body 1, and the wire 82 passes through the movement space and can move in the movement space.

[0035] In this embodiment, the limiting plate 7 can be fixed to the surface of the door module body 1 or a specific mounting base by means of buckles, screws or welding. A certain gap is maintained between the limiting plate 7 and the door module body 1, thereby forming a movement space. The wire 82 is arranged in the movement space and can slide up and down in the movement space, preventing it from leaving the movement space and swinging laterally in a large range, effectively preventing the wire 82 from interfering with the components located on its side.

[0036] In the optional technical solution of this embodiment, a limiting rib 14 is provided on the door module body 1. The limiting rib 14 is used to separate the wire 82 to limit the movement trajectory of the wire 82.

[0037] In this embodiment, multiple limiting ribs 14 are provided. These limiting ribs 14 can be protruding ribs integrally injection molded with the door module body 1 and located within the area covered by the limiting plate 7 or upstream and downstream of it. These ribs can be arranged parallel or intersecting, and their function is to divide the movement space into several channels. The limiting ribs 14 separate the wires 82, preventing multiple wires 82 from tangling together and forcing a single wire 82 to move along the interval defined by the limiting ribs 14. This further refines and optimizes the constraint effect, improving the stability of the system.

[0038] In this preferred embodiment, the limiting rib 14 is provided with three ribs.

[0039] In the optional technical solution of this embodiment, an assembly cover 11 is also included; an opening 15 is provided on the door module body 1, and the assembly cover 11 is openable and closable at the opening 15; when the assembly cover 11 is opened, the wiring harness plug of the door glass can be connected or disconnected through the first connector 81 of the opening 15.

[0040] In this embodiment, an opening 15 is formed on the door module body 1, with the opening 15 positioned directly opposite the interface between the first connector 81 and the door glass wiring harness connector. A mounting cover 11 is detachably mounted at this opening 15 via hinges, clips, or screws. When the mounting cover 11 is closed, it provides a seal, preventing water, dust, and other contaminants from entering the door interior through the opening 15 and affecting electrical connections or corroding components. When maintenance or replacement is required, opening the mounting cover 11 directly exposes the operating area through the opening 15, allowing technicians to easily and quickly connect or disconnect the first connector 81, greatly improving system maintainability and eliminating cumbersome disassembly steps.

[0041] In the optional technical solution of this embodiment, it further includes: a first glass bracket 3, a second glass bracket 9, and a drive mechanism; the first glass bracket 3 and the second glass bracket 9 are both set on the door module body 1 through guide rails, and the first glass bracket 3 and the second glass bracket 9 are both connected to the door glass; the drive mechanism is connected to the first glass bracket 3 and the second glass bracket 9 for driving the first glass bracket 3 and the second glass bracket 9 to rise and fall along the guide rails to drive the door glass to rise and fall.

[0042] In this embodiment, the first glass bracket 3 and the second glass bracket 9 are movably connected to a guide rail mounted on the door module body 1 via sliders or rollers. The two brackets together clamp or bond the door glass. The drive mechanism is connected to the brackets and drives them to move along the guide rail, thereby raising and lowering the glass. The electrical system is integrated with a traditional window regulator into a highly integrated door module. This modular design makes the entire door system more compact, reduces the number of parts, simplifies the assembly process at the vehicle manufacturer, and improves production efficiency and system reliability.

[0043] In the optional technical solution of this embodiment, the driving mechanism includes a cable 6, a winding wheel seat 4, and a motor 12; a winding wheel is provided on the winding wheel seat 4; the motor 12 is provided on the winding wheel seat 4 and is drivenly connected to the winding wheel; one end of the cable 6 is connected to the winding wheel, and the other end passes around the guide wheel 5 and is drivenly connected to the first glass bracket 3 and the second glass bracket 9 respectively; the motor 12 drives the winding wheel to rotate, and drives the first glass bracket 3 and the second glass bracket 9 to rise and fall along the guide rail through the cable 6.

[0044] In the optional technical solution of this embodiment, the cable 6 is provided with three sections, namely the first section, the second section and the third section; one end of the first section is connected to the winding reel and the other end is connected to the first glass bracket 3; one end of the second section is connected to the first glass bracket 3 and the other end is connected to the second glass bracket 9; one end of the third section is connected to the second glass bracket 9 and the other end is connected to the winding reel.

[0045] In this embodiment, the drive mechanism includes a motor 12, a winding reel seat 4 (containing a winding reel), and a cable 6. The motor 12 drives the winding reel to rotate forward and backward, thus winding and unwinding the cable 6. Preferably, the cable 6 adopts a three-section closed-loop arrangement: the first section connects the winding reel to the first glass bracket 3, the second section connects the two glass brackets, and the third section connects the second glass bracket 9 to the winding reel. A guide wheel 5 is used to change the direction of the cable 6. The connection method at both ends of each section of the cable can be either snap-fit ​​or fixed. The three-section cable 6 arrangement constitutes a stable closed-loop transmission system, which can smoothly and synchronously drive the two glass brackets, ensuring that the glass does not tilt or jam during lifting and lowering. The entire drive system has a compact structure and efficient and reliable power transmission.

[0046] In this embodiment, the optional technical solution also includes a sealing strip 2; the sealing strip 2 is disposed between the door module body 1 and the door sheet metal assembly. The sealing strip 2 is made of rubber or elastic plastic and is laid at the interface between the door module body 1 and the door sheet metal assembly. The sealing strip 2 effectively fills the assembly gap between the door module body 1 and the door sheet metal, providing good sealing and sound insulation. It can prevent external moisture and dust from entering the interior of the door cavity, protecting the internal electrical and mechanical components, and also helps to improve the overall sound insulation performance of the vehicle.

[0047] The vehicle provided in this embodiment includes the above-mentioned power supply system based on the door module window regulator. Therefore, the technical advantages and effects achieved by the vehicle include the technical advantages and effects achieved by the above-mentioned power supply system based on the door module window regulator, which will not be repeated here.
