Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an electrical connection structure for car window glass, a car window regulator, and a car. Background Technology

[0002] With the increasing functionality of automotive windows, such as tinted glass, electrical connections are required between windows and other vehicle components like doors to meet their connectivity needs with power sources and onboard control modules. In related technologies, windows typically use additional flexible wiring harnesses to connect to the door wiring harness. During window operation, this flexible harness adapts to deformation and movement to maintain the connection between the window and the door wiring harness. However, this wiring harness requires separate assembly from the window regulator, adding assembly stations and processes and slowing down the assembly process. Furthermore, the relatively large size of the wiring harness requires ample space within the door cavity, making it difficult to arrange other components inside the door. Additionally, the wiring harness is prone to interference and entanglement with other components during the deformation process of the window, leading to product malfunctions. Utility Model Content

[0009] Optionally, the guide rail includes a first part, which is an insulator and extends along the lifting trajectory of the car window glass, and there are two electrodes, which are respectively disposed on opposite sides of the first part.

[0010] Optionally, the guide rail further includes a second part, which covers the electrode and forms a cavity with the first part for the conductive member to slide through. The cavity extends along the extension direction of the electrode, and a sliding groove for the conductive member to pass through is formed on the inner wall of the cavity. The sliding groove extends along the extension direction of the electrode.

[0011] Optionally, there are two second parts, each corresponding to one of the electrodes, and the two second parts respectively form the cavity with the first part.

[0012] Optionally, the openings of the sliding grooves in the two cavities face the same direction.

[0013] Optionally, the first part is plate-shaped, and the two electrodes are respectively disposed on two sides of the first part. The sliding groove is formed between the edge of the first part and the edge of the second part. The first part is provided with a lip that protrudes from the edge of the first part and extends along the extension direction of the first part. The protruding direction of the lip is the same as the opening direction of the sliding groove.

[0014] Optionally, there are two conductive components, each corresponding to one of the electrodes. The electrical connection structure further includes a connector, with both conductive components connected to the same connector, and the lip fitting against the connector.

[0015] Optionally, the electrode is sheet-shaped and attached to the side of the first part.

[0016] Optionally, the cavity is provided with a drain hole at the bottom in the vertical direction.

[0022] As described above, the electrical connection structure for a vehicle window, a window regulator, and a vehicle according to this utility model have the following beneficial effects: Since the electrode extends along the lifting trajectory of the window, and the conductive component is in conductive contact with the electrode and can slide relative to the electrode along the extension direction of the electrode, the electrode can be fixed relative to the vehicle body, while the conductive component is fixed relative to the window, or the electrode can also be fixed relative to the window, while the conductive component is fixed relative to the vehicle body.

Simultaneously, when the conductive component moves relative to the electrode, its movement envelope is relatively small, occupying little space, which is beneficial for the layout of components within the vehicle body and also for simplifying the vehicle body structure, especially the door structure.

Detailed Implementation

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0033] Please see Figures 1 to 8 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

[0034] Vehicles typically have power windows, especially on the doors, to open or close and maintain visibility from inside the vehicle when closed. The functionality of vehicle windows is gradually increasing; for example, some windows use tinted glass for privacy and light control. Common tinted glass includes electrochromic glass, which changes color under the influence of an electric current.

[0035] Taking car doors as an example, with the increasing functionality of car windows, such as tinted glass, these windows need to be electrically connected to the car body and doors to meet their connectivity requirements with power sources and onboard control modules. In related technologies, car windows typically use additional flexible wiring harnesses to connect to the car body wiring harness. During window operation, this flexible harness adapts to deformation and movement to maintain the connection between the window and the door wiring harness. However, this wiring harness needs to be packaged separately from the window regulator, adding additional assembly stations and processes, slowing down the assembly process. The wiring harness structure is relatively large, requiring significant space within the door cavity, making it difficult to arrange other components inside the door. Furthermore, during the deformation process of the window during operation, the wiring harness is prone to interference and entanglement with other components, leading to product malfunctions.

[0036] In view of this, please refer to Figures 1-8 This embodiment provides an electrical connection structure for a vehicle window glass. The electrical connection structure includes electrodes (2a, 2b) and conductive components (3a, 3b). The electrodes are rigid structures or supported on rigid structures. The electrodes (2a, 2b) extend along the lifting trajectory of the vehicle window glass. The conductive components (3a, 3b) are slidably disposed relative to the electrodes (2a, 2b) along the extension direction of the electrodes (2a, 2b). The conductive component 3a is in conductive contact with the electrode 2a, and the conductive component 3b is in conductive contact with the electrode 2b.

[0037] The electrodes (2a, 2b) can be fixed relative to the vehicle body, while the conductive components (3a, 3b) are fixed relative to the vehicle window glass. When the vehicle window glass is raised or lowered, the conductive components (3a, 3b) move up and down along with the vehicle window glass. Alternatively, the electrodes (2a, 2b) can be fixed relative to the vehicle window glass, while the conductive components (3a, 3b) are fixed relative to the vehicle body. When the vehicle window glass is raised or lowered, the electrodes (2a, 2b) move up and down along with the vehicle window glass.

[0038] In this embodiment, the electrodes (2a, 2b) extend along the lifting trajectory of the car window glass, and the conductive member 3a is in conductive contact with the electrode 2a, the conductive member 3b is in conductive contact with the electrode 2b, and the conductive member 3a can slide relative to the electrode 2a along the extension direction of the electrode 2a, and the conductive member 3b can slide relative to the electrode 2b along the extension direction of the electrode 2b. The electrodes (2a, 2b) are fixed relative to the car window glass, and the conductive members (3a, 3b) are fixed relative to the car door. Alternatively, the electrodes (2a, 2b) are fixed relative to the car door, and the conductive members (3a, 3b) are fixed relative to the car window glass.

[0039] Therefore, when the car window is raised or lowered, during the relative sliding of conductive component 3a and electrode 2a, and the relative sliding of conductive component 3b and electrode 2b, conductive component 3a can maintain conductive connection with electrode 2a, and conductive component 3b can maintain conductive connection with electrode 2b. This allows the car door to continuously supply power or send electrical signals to the car window through conductive components (3a, 3b) and electrodes (2a, 2b) during the raising or lowering of the car window.

[0040] Specifically, in one optional embodiment of this example, the car door can supply power to the car window glass via conductive components (3a, 3b) and electrodes (2a, 2b), and adjust the glass color by controlling the magnitude of the current. In another optional embodiment of this example, the car window glass can also have its own power source, and the car door can send control information to the car window glass by sending current pulse signals to the car window glass, thereby adjusting the glass color.

[0041] In this embodiment, the window is located on the door, and the electrodes (2a, 2b) and conductive components (3a, 3b) are fixedly mounted relative to the window glass and the door, respectively. It is understood that the door is part of the vehicle body, and the window glass can also be located on other parts of the vehicle body, such as the roof or the side panel near the third row of seats, rather than being limited to the door. In some alternative embodiments, the window glass can also be the sunroof glass of the vehicle, with the conductive components fixedly mounted on the sunroof glass, and the electrodes fixedly mounted on the roof.

[0042] In this embodiment, the electrodes (2a, 2b) are fixedly installed inside the car door, that is, fixedly installed relative to the car body, while the conductive components (3a, 3b) are fixedly installed relative to the car window glass, meaning that the conductive components (3a, 3b) move up and down with the car window glass. The conductive components (3a, 3b) are typically small in size and weight, and when they move with the car window glass, the resulting motion envelope is small. This helps reduce the risk of motion interference between internal car door components and also helps reduce the motion inertia of the car window glass, improving the response speed of the car window glass's raising and lowering. The electrodes (2a, 2b), on the other hand, are relatively large in size. Since the electrodes (2a, 2b) are fixedly installed relative to the car door, they do not require additional movement, which facilitates the placement of the electrodes (2a, 2b).

[0043] The electrodes (2a, 2b) are fixed relative to the door, reducing the risk of deformation and movement of the electrodes (2a, 2b) during the raising and lowering of the window glass, thereby reducing the risk of interference between the electrical connection structure and other components. Simultaneously, the movement envelope of the conductive components (3a, 3b) relative to the electrodes (2a, 2b) is relatively small, requiring less space, which is beneficial for the layout of components within the vehicle body and for simplifying the vehicle body structure. Furthermore, the narrow internal cavities (6a, 6b) of the door, coupled with the small movement envelope of the conductive components (3a, 3b) relative to the electrodes (2a, 2b), further facilitate the layout of components within the door and simplify the door structure.

[0044] In some alternative embodiments, the electrodes (2a, 2b) are themselves rigid structures, and their deformation is small when subjected to external forces. This results in a smaller deformation amplitude when the conductive components (3a, 3b) and the electrodes (2a, 2b) move relative to each other, which helps reduce the risk of interference between the electrical connection structure (3a, 3b), the electrodes (2a, 2b), and surrounding components. In other alternative embodiments, the electrodes (2a, 2b) can also be mounted on rigid structures such as rigid components or rigid parts of components. The rigid structure supports the electrodes (2a, 2b), which helps reduce the displacement of the electrodes (2a, 2b) after being subjected to external forces, thereby reducing the risk of interference between the electrical connection structure (3a, 3b), the electrodes (2a, 2b), and surrounding components.

[0045] It is understood that in this embodiment, a rigid structure is used in contrast to a flexible structure such as a cable. In its operating environment, a rigid structure can maintain its shape and size approximately unchanged when subjected to external forces. Rigid structures can be manufactured by selecting appropriate structural forms and materials such as engineering plastics, which will not be elaborated further here.

[0046] Specifically, in this embodiment, the electrical connection structure also includes a guide rail 10, on which the electrodes (2a, 2b) are mounted. The guide rail 10 extends along the lifting trajectory of the vehicle window glass. The guide rail 10 is a rigid structure with a certain structural strength, which can provide support for the electrodes (2a, 2b) and fix their positions. This helps maintain contact between the conductive components (3a, 3b) and the electrodes (2a, 2b) during relative movement, reducing the risk of the conductive components (3a, 3b) slipping off the electrodes (2a, 2b) during relative movement.

[0047] Specifically, in this embodiment, the guide rail 10 can be directly fixed to the lifting slide rail of the lifter using fasteners such as bolts and nuts. The car window glass moves up and down on the lifting slide rail, and the lifting slide rail also directly supports and constrains the guide rail 10. The dimensional chain between the car window glass and the electrodes (2a, 2b) is smaller, which helps to reduce the positional error between the extension direction of the electrodes (2a, 2b) and the lifting trajectory of the car window glass. This further helps to reduce the risk of the conductive components (3a, 3b) slipping off the electrodes (2a, 2b) during the relative movement with the electrodes (2a, 2b).

[0048] like Figures 1-7 As shown, in this embodiment, the guide rail 10 includes a first part 1, which is an insulator. The first part 1 extends along the lifting trajectory of the car window glass. There are two electrodes (2a, 2b), which are respectively disposed on opposite sides of the first part 1. The first part 1 is also a support part, which directly supports the two electrodes (2a, 2b). Electrical appliances such as tinted glass usually need to be connected to both positive and negative terminals simultaneously. Therefore, in this embodiment, the two electrodes (2a, 2b) on the first part 1 can be positive and negative terminals respectively. The first part 1 is an insulator, which can prevent the two electrodes (2a, 2b) from short-circuiting through the first part 1, thus ensuring the reliability and safety of the electrical connection structure. The two electrodes (2a, 2b) are respectively disposed on opposite sides of the first part 1, so that the two electrodes (2a, 2b) are less likely to come into accidental contact, thereby further improving the reliability and safety of the electrical connection structure.

[0049] In this embodiment, the guide rail 10 further includes a second part (5a, 5b), which covers the electrodes (2a, 2b) and together with the first part 1 forms a cavity (6a, 6b) for the conductive members (3a, 3b) to slide through. The cavity (6a, 6b) extends along the extension direction of the electrodes (2a, 2b), that is, the extension direction of the cavity (6a, 6b) is the same as the extension direction of the electrodes (2a, 2b). It is understood that the cavity (6a, 6b) needs to have sufficient size to facilitate the placement of the battery cell and to facilitate the passage of the conductive members (3a, 3b) when they move relative to the electrodes (2a, 2b).

[0050] The inner wall of the cavity (6a, 6b) is provided with sliding grooves (7a, 7b) for the conductive components (3a, 3b) to pass through. The sliding grooves (7a, 7b) are through structures to facilitate the passage of the conductive components (3a, 3b). In other words, the conductive components (3a, 3b) can enter the cavity (6a, 6b) formed by the first part 1 and the second part (5a, 5b) through the sliding grooves (7a, 7b) so that the conductive components (3a, 3b) can make conductive contact with the electrodes (2a, 2b).

[0051] The sliding grooves (7a, 7b) extend along the extension direction of the electrodes (2a, 2b), respectively. When the car window glass is raised or lowered, the conductive components (3a, 3b) move together with the car window glass, and the conductive components (3a, 3b) slide within the sliding grooves (7a, 7b). The second part (5a, 5b) is also the protective part, which covers the electrodes (2a, 2b) respectively, and protects the electrodes (2a, 2b), reducing the probability of debris such as rainwater and iron filings entering the cavity (6a, 6b). This helps to avoid short circuits between the two electrodes (2a, 2b) due to water ingress, and improves the reliability and safety of the electrical connection structure.

[0052] In one optional embodiment of this example, the second part is one, that is, one electrode is located inside the cavity formed by the second part, and the other electrode is located outside the cavity formed by the second part. The second part acts as a separator between the two electrodes, which helps to avoid direct connection between the two electrodes and short circuit, thereby improving the reliability and safety of the electrical connection structure.

[0053] like Figures 1-7 As shown, in another optional embodiment of this example, there are two second parts, namely second part 5a and second part 5b, and the two second parts (5a, 5b) are arranged in a one-to-one correspondence with the two electrodes (2a, 2b). In this embodiment, second part 5a is arranged corresponding to electrode 2a and is in conductive contact with electrode 2a, and second part 5b is arranged corresponding to electrode 2b and is in conductive contact with electrode 2b.

[0054] Two second parts (5a, 5b) are each covered on the corresponding electrodes (2a, 2b). The two second parts (5a, 5b) form cavities with the first part 1 respectively. The two cavities formed are cavity 6a and cavity 6b.

[0055] The second part (5a, 5b) can relatively isolate the corresponding electrodes (2a, 2b) from the external environment. The increase in the number of the second part (5a, 5b) is beneficial to increase the isolation effect between the two electrodes (2a, 2b). While reducing the risk of accidental short circuit between the two electrodes (2a, 2b), it can also reduce the contamination of the electrodes (2a, 2b) by sewage, debris and other substances in the external environment. It is beneficial to maintain good contact between the conductive components (3a, 3b) and the electrodes (2a, 2b), and improve the reliability and safety of the electrical connection structure.

[0056] In this embodiment, the opening direction of the sliding grooves (7a, 7b) on the cavities (6a, 6b) corresponds to the setting position of the conductive components (3a, 3b), and can be adjusted according to the actual setting position of the conductive components (3a, 3b) to reduce the length of the conductive components (3a, 3b). Figures 1-7 As shown, in this embodiment, the openings of the sliding grooves (7a, 7b) of the two cavities (6a, 6b) face the same direction, that is, the openings of the sliding grooves (7a, 7b) of the two cavities (6a, 6b) face the same side of the guide rail 10. The two conductive components (3a, 3b) can pass into the guide rail 10 from the same side of the guide rail 10 and contact their respective corresponding electrodes (2a, 2b). The two conductive components (3a, 3b) are arranged in a concentrated manner, and the clearance space for the conductive components (3a, 3b) in the car door can also be concentrated, which helps to simplify the internal structure of the car door.

[0057] Specifically, such as Figures 4-6 As shown, in this embodiment, the first part 1 is plate-shaped, with two electrodes (2a, 2b) respectively disposed on two opposite sides of the first part 1. The plate shape has two large opposing surfaces, and the electrodes (2a, 2b) are respectively disposed on the two large surfaces. The plate structure is simple, small in size, and can provide sufficient space for the electrodes (2a, 2b). The plate structure can also effectively separate the electrodes (2a, 2b) disposed on both sides of the plate structure. Compared with other shapes, this helps to prevent rainwater from flowing over the edge of the first part 1 and causing an accidental short circuit between the two electrodes (2a, 2b).

[0058] like Figure 5 and Figure 6As shown, the first part 1 is thickened at the location where the electrodes (2a, 2b) are set to form an installation step. The installation step helps to reduce the machining dimensions of the mounting surface of the electrodes (2a, 2b), reduce the machining difficulty, and also helps to increase the strength of the first part 1 at the mounting position of the electrodes (2a, 2b), reduce the deformation of the electrodes (2a, 2b) during the working process, and help to maintain good contact between the conductive components (3a, 3b) and the electrodes (2a, 2b).

[0059] In this embodiment, sliding grooves (7a, 7b) are formed between the edge of the first part 1 and the edge of the second part (5a, 5b). A lip 8 is provided on the edge of the first part 1, protruding from the edge of the first part 1 and extending along the extension direction of the first part 1. The protruding direction of the lip 8 is the same as the opening direction of the sliding groove (7a, 7b), that is, the lip 8 protrudes from the inside of the sliding groove (7a, 7b) to the outside of the sliding groove (7a, 7b). The lip 8 helps to improve the separation effect of the first part 1 on the two electrodes (2a, 2b) and prevent rainwater and other substances from flowing over the first part 1 from the edge of the first part 1, causing an accidental short circuit between the two electrodes (2a, 2b).

[0060] In this embodiment, the guide rails 10 are all made of insulating material, that is, the first part 1 and the second part (5a, 5b) are both insulators, which helps to avoid short circuits between the two electrodes (2a, 2b) and also helps to avoid accidental conduction between the electrodes (2a, 2b) and external components, thereby improving the reliability and safety of the electrical connection structure.

[0061] like Figures 2-4 As shown, in this embodiment, there are two conductive components (3a, 3b), and each of the two conductive components (3a, 3b) is respectively configured to correspond one-to-one with the two electrodes (2a, 2b). Specifically, in this embodiment, conductive component 3a is configured to correspond to electrode 2a, and conductive component 3b is configured to correspond to electrode 2b. Conductive component 3a is in conductive contact with electrode 2a, and conductive component 3b is in conductive contact with electrode 2b.

[0062] In this embodiment, the first part 1 is sandwiched between two conductive components (3a, 3b). The two conductive components (3a, 3b) cooperate with the first part 1. The first part 1 guides the conductive assembly 20 through the two conductive components (3a, 3b), so that when the conductive assembly 20 moves up and down with the glass, the movement trajectory of the two conductive components (3a, 3b) can be better aligned with the extension direction of the electrodes (2a, 2b), which is beneficial to maintaining good conductive contact between the conductive components (3a, 3b) and the electrodes (2a, 2b).

[0063] The connector 4 connects the two conductive components (3a, 3b) together and combines with the two conductive components (3a, 3b) to form a conductive assembly 20. This improves the structural strength of the conductive assembly 20 and helps to reduce the deformation of the conductive components (3a, 3b) when they slide relative to the electrodes (2a, 2b). This helps to prevent the conductive components (3a, 3b) from losing contact with the electrodes (2a, 2b) due to excessive deformation, thereby improving the electrical connection reliability and safety of the electrical connection structure.

[0064] In this embodiment, the electrical connection structure also includes a connector 4, on which two conductive components (3a, 3b) are connected. A lip 8 is attached to the connector 4. The lip 8 is attached to the connector 4, which means that the lip 8 seals and separates the surfaces of the connector 4 that are attached to the lip 8. This helps to prevent liquids such as rainwater from flowing from one electrode (2a, 2b) to the other electrode (2a, 2b), thereby preventing short circuits between the two electrodes (2a, 2b) and improving the reliability and safety of the electrical connection structure.

[0065] like Figure 4 , Figure 5 As shown, in this embodiment, the electrodes (2a, 2b) are sheet-like and attached to the side of the first part 1. The sheet-like structure is simple and, with the same mass, can provide a larger contact area for the conductive components (3a, 3b), which is beneficial for the conductive components (3a, 3b) to maintain reliable contact with the electrodes (2a, 2b) during movement.

[0066] In this embodiment, the cavities (6a, 6b) are provided with drainage holes at the bottom in the vertical direction. The drainage holes facilitate the drainage of liquids such as rainwater that accidentally enter the cavities (6a, 6b), preventing the accumulation of rainwater due to slow drainage, which could lead to the simultaneous immersion of both electrodes (2a, 2b) and short circuit, thereby improving the reliability and safety of the electrical connection structure.

[0067] like Figure 7 As shown, in this embodiment, the conductive components (3a, 3b) include a connecting portion and contact portions (32a, 32b). The connecting portion is an elastic body (31a, 31b), and the contact portions (32a, 32b) are attached to the electrodes (2a, 2b). The connecting portion presses the contact portions (32a, 32b) firmly onto the electrodes (2a, 2b). By pressing the contact portions (32a, 32b) firmly onto the electrodes (2a, 2b), the connecting portion ensures that the contact portions (32a, 32b) maintain good contact with the electrodes (2a, 2b) under conditions such as vibration, reducing the risk of the contact portions (32a, 32b) accidentally detaching from the electrodes (2a, 2b) and improving the reliability and safety of the electrical connection structure.

[0068] Specifically, in this embodiment, the connecting part is a spring, and the contact parts (32a, 32b) are carbon brushes. The spring has a simple structure and is lightweight, providing sufficient elasticity to the contact parts (32a, 32b) so that the contact parts (32a, 32b) can fit well with the electrodes (2a, 2b). The carbon brush has good conductivity and self-lubricating properties, which can reduce the coefficient of friction between the conductive components (3a, 3b) and the electrodes (2a, 2b), reduce carbon brush wear, and help reduce the resistance of the window glass to rise and fall.

[0069] This utility model also provides a vehicle window regulator, including the electrical connection structure described above. Vehicle window regulators typically include cable-operated and cross-arm types. Taking the cable-operated type as an example, the vehicle window regulator mainly includes a lifting rail, a lifting motor, and a steel cable. A glass slider 11 is fixedly installed on the vehicle window glass, and the vehicle window glass slides on the lifting rail via the glass slider 11. The lifting rail constrains the lifting trajectory of the vehicle window glass. The steel cable is connected to the vehicle window glass, and the lifting motor drives the vehicle window glass to rise and fall via the steel cable.

[0070] like Figure 8 As shown, in this embodiment, the conductive component 20 is integrated with the glass slider 11. The conductive component 20 also includes a plug-in harness 9. One end of the plug-in harness 9 is connected to the conductive components (3a, 3b), and the other end of the plug-in harness 9 is provided with a plug for connecting to the electrical structure of the vehicle window glass.

[0071] This embodiment also provides an automobile, including a body, a window provided on the body, and a retractable window glass provided inside the window, the window glass being connected to the body via the electrical connection structure described above.

[0072] Specifically, in this embodiment, the window is located on the door, and a window regulator as described above is installed inside the door to drive the glass up and down. In this embodiment, the window glass is a dimming glass, which is connected to a power source or signal source on the door via an electrical connection structure.

[0073] Two or more electrical connection structures can be set, and the dimming glass can also be connected to the power and signal sources on the car door simultaneously through different electrical connection structures.

[0074] In summary, the electrical connection structure for a vehicle window, the window regulator, and the vehicle described in this embodiment involve electrodes extending along the window's lifting trajectory, and conductive components making conductive contact with the electrodes and sliding relative to them along their extension direction. The electrodes and conductive components are fixedly positioned relative to the window and the vehicle door, respectively. Specifically, the electrodes can be fixed relative to the door, while the conductive components are fixed relative to the window, or vice versa. When the window is raised or lowered, the conductive components maintain conductive contact with the electrodes, allowing the door to supply power or send electrical signals to the window via the conductive components and electrodes. The fixed electrode configuration reduces the risk of deformation or movement during the window's raising and lowering process, thereby reducing the risk of interference between the electrical connection structure and other components. Furthermore, the relatively small movement envelope of the conductive components relative to the electrodes reduces the space required, facilitating the layout of components within the door and simplifying the door structure.

[0075] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
