Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a wiring harness restraint device, a car door, and a vehicle. Background Technology

[0002] Automotive dimming glass is a type of glass whose transparency can be changed through electronic, temperature, or light control. It can replace sunshades, improve interior space, reduce direct sunlight, and make the occupants more comfortable.

[0003] Currently, the most common and widely used type of automotive dimming glass uses electronic control for dimming, allowing the glass to switch instantly between transparent and opaque states. Because dimming is electronically controlled, a wiring harness is required to connect to the glass. Once connected, the harness moves with the glass during operation, which can cause scratches against surrounding components and even affect the smoothness of the glass's movement. Summary of the Invention

[0004] (i) The technical problem to be solved by the present invention is that in the process of raising and lowering the glass of existing automotive dimming glass, the wiring harness also moves with the glass. During the movement of the wiring harness, it will scratch the surrounding parts and even affect the smoothness of the glass raising and lowering.

[0005] (II) Technical Solution To address the aforementioned technical problems, embodiments of the present invention provide a wiring harness constraint device installed inside a car door. The car door includes a door base plate, on which a lifter is slidably mounted. The wiring harness constraint device includes a wiring harness and a limiting mechanism. One end of the wire harness is disposed on the door base plate, and the other end of the wire harness is connected to the dimming glass installed on the lifter. The lifter can rise or fall along the height direction of the door base plate, and the wire harness can move with the lifter. The limiting mechanism is mounted on the door base plate, and the side of the limiting mechanism facing the door base plate forms a displacement space that can cover the movement path of the wire harness.

[0006] Furthermore, the limiting mechanism includes a limiting cover plate and a connecting assembly; The limiting cover plate has the displacement space on the side facing the door base plate, and the limiting cover plate is detachably installed on the door base plate through the connecting assembly.

[0007] Furthermore, the connecting component includes connecting ears, and a plurality of connecting ears are arranged at circumferential intervals along the limiting cover plate, and the connecting ears are connected to the door base plate.

[0008] Furthermore, the connecting assembly also includes bolts, and each connecting lug is provided with a through hole. The bolts correspond one-to-one with the through holes, and the bolts pass through the through holes to be threadedly connected to the door base plate.

[0009] Furthermore, the door base plate has a threaded hole, and the bolt passes through the through hole and is threadedly connected to the threaded hole.

[0010] Furthermore, the limiting cover plate is provided with a clearance area, which is used to avoid the connection between the wire harness and the door base plate.

[0011] Furthermore, the end of the limiting cover facing the connection between the wire harness and the door base plate is provided with a groove, and the groove forms the avoidance area.

[0012] Furthermore, the limiting cover plate is also provided with a weight reduction groove.

[0013] An embodiment of the present invention also provides a vehicle door, including the above-described wiring harness restraint device.

[0014] Embodiments of the present invention also provide a vehicle including the aforementioned door.

[0015] The beneficial effects of this invention are: This invention provides a wiring harness constraint device, including a wiring harness and a limiting mechanism. When an electrically controlled dimming glass is installed inside a car door, a wiring harness is connected to the dimming glass inside the door. When the dimming glass is raised and lowered along the height of the car door by a lifter, since one end of the wiring harness is located on the door base plate, the wiring harness will inevitably be displaced, resulting in a certain movement path for the wiring harness. After a limiting mechanism is provided on the door base plate, the side of the limiting mechanism facing the door base plate forms a displacement space. The range of the displacement space can effectively cover the entire movement path of the wiring harness, thereby ensuring that when the wiring harness is displaced with the lifter, it will only move within the displacement space and will not exceed the range of the displacement space. In other words, it will not interfere with other surrounding parts or cause scratches, which can effectively ensure the smoothness of the dimming glass raising and lowering and can also significantly improve the service life of the wiring harness.

[0016] The present invention provides a car door including the above-mentioned wiring harness constraint device. When the car door is equipped with a dimming glass, by using the above-mentioned wiring harness constraint device to constrain the wiring harness connected to the dimming glass, it can effectively prevent the dimming glass from causing displacement of the wiring harness during the lifting and lowering process, avoid interference with other surrounding parts during the movement of the wiring harness, and thus avoid scratches. It can effectively ensure the smoothness of the lifting and lowering process of the dimming glass, thereby improving the smoothness of the car door and the overall comfort of the user.

[0017] The present invention provides a vehicle including the aforementioned door. By using the aforementioned door, the smoothness and fluidity of the raising and lowering of the dimming glass can be effectively ensured, thus fully guaranteeing the overall comfort of the vehicle and the user's experience.

[0024] Example 1 like Figures 1 to 3 As shown, the present invention provides a wiring harness restraint device, which is installed inside the door of an automobile. The door includes a door base plate 100, on which a lifter 101 is slidably mounted. The wiring harness restraint device includes a wiring harness 200 and a limiting mechanism. One end of the wiring harness 200 is disposed on the door base plate 100, and the other end of the wiring harness 200 is connected to the dimming glass installed on the lift 101. The lift 101 can rise or fall along the height direction of the door base plate 100, and the wiring harness 200 can move with the lift 101. The limiting mechanism is mounted on the door base plate 100, and the side of the limiting mechanism facing the door base plate 100 forms a displacement space that can cover the movement path of the wire harness 200.

[0025] In this embodiment, the wiring harness constraint device includes a wiring harness 200 and a limiting mechanism. When an electronically controlled dimming glass is installed inside the car door, the wiring harness 200 is connected to the dimming glass inside the car door. When the dimming glass is moved up and down along the height direction of the car door by the lifter 101, since one end of the wiring harness 200 is located on the door base plate 100, the wiring harness 200 will inevitably be displaced, resulting in a certain movement path for the wiring harness 200. After the limiting mechanism is provided on the door base plate 100, the side of the limiting mechanism facing the door base plate 100 forms a displacement space. The range of the displacement space can effectively cover the entire movement path of the wiring harness 200, thereby ensuring that when the wiring harness 200 is displaced with the lifter 101, it will only move within the displacement space and will not exceed the range of the displacement space. In other words, it will not interfere with other surrounding parts or cause scratches. This can effectively ensure the smoothness of the dimming glass lifting and lowering, and can also significantly improve the service life of the wiring harness 200.

[0026] According to one embodiment provided by the present invention, such as Figure 1 As shown, the limiting mechanism includes a limiting cover plate 300 and a connecting assembly; The limiting cover 300 has a displacement space on the side facing the door base plate 100, and the limiting cover 300 can be detachably installed on the door base plate 100 through the connecting assembly.

[0027] In this embodiment, since the side of the limiting cover 300 facing the door substrate 100 forms a displacement space, the side of the limiting cover 300 away from the door substrate 100 will bulge. That is to say, the side of the limiting cover 300 away from the door substrate 100 is arc-shaped, which facilitates the formation of a displacement space for the wire harness 200 to move. Of course, the limiting cover 300 can also be detachably installed on the door substrate 100 through a connecting component. When the wire harness 200 fails, the limiting cover 300 can be directly removed from the door substrate 100, and then the wire harness 200 can be repaired or replaced before the limiting cover 300 is installed. The whole process is very convenient.

[0028] According to one embodiment provided by the present invention, such as Figure 2 As shown, the connecting component includes connecting ears 301, and multiple connecting ears 301 are arranged at intervals along the circumference of the limiting cover plate 300. The connecting ears 301 are connected to the door base plate 100.

[0029] In this embodiment, in order to facilitate the detachable installation of the limiting cover 300 onto the door base plate 100, a plurality of connecting ears 301 are provided at intervals along the circumference of the edge of the limiting cover 300, so that it can be directly connected to the door base plate 100 through the connecting ears 301, thereby realizing the detachable connection between the limiting cover 300 and the door base plate 100.

[0030] According to one embodiment provided by the present invention, such as Figure 1 As shown, the connecting assembly also includes bolts, and each connecting lug 301 has a through hole. The bolts correspond one-to-one with the through holes, and the bolts pass through the through holes to be threadedly connected to the door base plate 100.

[0031] In this embodiment, for ease of installation, a through hole is provided in the connecting ear 301. Preferably, the through hole is located at the center of the connecting ear 301. The connecting ear 301 is threaded to the door base plate 100 by passing a bolt through the through hole, thereby threading the limiting cover plate 300 to the door base plate 100. The limiting cover plate 300 is detachably connected to the door base plate 100 through the connecting ear 301.

[0032] Alternatively, bolts can be replaced by fasteners such as screws, pins, or pins. The purpose of these alternatives is not to deviate from the design concept of this invention and they should fall within the protection scope of this invention.

[0033] According to one embodiment of the present invention, the door base plate 100 is provided with a threaded hole, and the bolt passes through the through hole and the threaded hole for threaded connection.

[0034] In this embodiment, in order to match the through hole of the connecting ear 301, a corresponding threaded hole is provided on the door base plate 100. Then, a bolt is threaded through the through hole and the threaded hole to install the connecting ear 301 on the door base plate 100. The outer wall surface of the connecting ear 301 is tightly attached to the inner wall surface of the door base plate 100 through the threaded connection to ensure that it will not squeeze the limited space inside the car door. This ensures that the setting of the limiting cover 300 will not interfere with other parts inside the car door except for the wiring harness 200.

[0035] Among them, threaded holes can be pre-set directly on the door base plate 100, and connecting posts can also be pre-set on the door base plate 100 according to actual use, with threaded holes opened on the connecting posts, so as to install the limiting cover plate 300 on the door base plate 100.

[0036] Of course, the limiting cover plate 300 and the door base plate 100 can also be detachably connected by snap-fit. That is, a baffle is provided on the door base plate 100 along the edge of the moving path of the wire harness 200. Multiple snap-fit ​​holes are provided on the baffle at intervals along the circumference of the baffle. Correspondingly, multiple buckles are provided on the side of the limiting cover plate 300 facing the door base plate 100 at intervals along the circumference of the door base plate 100. Alternatively, multiple buckles are provided on the door base plate 100 at intervals along the edge of the moving path of the wire harness 200. Correspondingly, multiple snap-fit ​​holes are provided on the side of the limiting cover plate 300 facing the door base plate 100 at intervals along the circumference of the door base plate 100. The detachable connection between the limiting cover plate 300 and the door base plate 100 is achieved by the snap-fit ​​cooperation of the buckles and the snap-fit ​​holes. Optionally, the limiting cover plate 300 and the door base plate 100 may also include, but are not limited to, the above-mentioned detachable connection methods. As long as the two can be detachably connected, the purpose is not to deviate from the design concept of the present invention and should fall within the protection scope of the present invention.

[0037] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the limiting cover plate 300 is provided with a clearance area, which is used to avoid the connection between the wire harness 200 and the door base plate 100.

[0038] Furthermore, the end of the limiting cover 300 facing the connection between the wiring harness 200 and the door base plate 100 is provided in the groove 302, and the groove 302 forms a clearance area.

[0039] In this embodiment, to facilitate confirmation of the connection status at the connection point between the wiring harness 200 and the door substrate 100, a groove 302 is provided on the limiting cover plate 300. The groove 302 can be formed by directly removing a corner bracket from the limiting cover plate 300 or by extending inward along the edge of the limiting cover plate 300. Thus, the groove 302 forms a clearance area, exposing the connection point between the wiring harness 200 and the door substrate 100 to the limiting cover plate 300. This allows for a direct confirmation of the connection status at the connection point between the wiring harness 200 and the door substrate 100, making it easier to determine if there is a problem with the wiring harness 200 and facilitating repairs when a problem occurs.

[0040] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the limiting cover plate 300 is also provided with a weight reduction groove 303.

[0041] In this embodiment, optionally, the limiting cover 300 is made of prefabricated plastic parts. In order to further ensure that the weight of the limiting cover 300 can be effectively reduced, a weight reduction groove 303 is also provided on the limiting cover 300. The weight reduction groove 303 reduces the overall weight of the limiting cover 300, thereby ensuring that the door using the limiting cover 300 can meet the lightweight standard.

[0042] By creating a groove 302 and a weight-reducing groove 303 on the limiting cover plate 300, the limiting cover plate 300 presents an overall convex shape, which can avoid the connection between the wire harness 200 and the door base plate 100, and also reduce the weight of the limiting cover plate 300, thereby ensuring stability in use.

[0043] Of course, multiple weight-reducing holes can be provided on the limiting cover plate 300 instead of the weight-reducing groove 303. The shape of the weight-reducing holes can be circular, square or rhomboid, etc. The purpose of these holes is not different from the design concept of this invention and should be within the protection scope of this invention.

[0044] Example 2 The present invention provides a vehicle door, including the above-described wiring harness restraint device.

[0045] In this embodiment, the car door includes the aforementioned wiring harness constraint device. When the car door is fitted with a dimming glass, the wiring harness 200 connected to the dimming glass is constrained by the aforementioned wiring harness constraint device. This effectively prevents the wiring harness 200 from shifting during the raising and lowering of the dimming glass, avoids interference between the wiring harness 200 and other surrounding parts during the movement of the wiring harness 200, and prevents scratches. This effectively ensures the smoothness of the raising and lowering process of the dimming glass, thereby improving the smoothness of the car door and the overall comfort of the user.

[0046] Of course, if there are other electronic control components in the car door that need to be connected using the wiring harness 200, and the wiring harness 200 is displaced during the use of the car door, the above-mentioned wiring harness restraint device can also be used. The above-mentioned wiring harness restraint device includes, but is not limited to, restraining only the wiring harness 200 used for connecting the dimming glass.

[0047] Example 3 The present invention provides a vehicle including the aforementioned door.

[0048] In this embodiment, the vehicle includes the aforementioned door. By using the aforementioned door, the smoothness and fluidity of the raising and lowering of the dimming glass can be effectively ensured, thus fully guaranteeing the overall comfort of the vehicle and the user's experience.

[0049] The aforementioned vehicles can be two-door, four-door, or even multi-door models. Correspondingly, they can also be vehicles with the aforementioned wiring harness restraint device installed only in one or more of the door mounting positions, while the other door mounting positions are equipped with doors that do not use the aforementioned wiring harness restraint device. This is not limited here, and the purpose of each is not different from the design concept of the present invention, and they should fall within the protection scope of the present invention.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
