Therefore, they should not be construed as limitations on the present invention.
[0026] like Figure 1-Figure 2 As shown, a motor base plate of an embodiment of the present invention is used for a double-guide-rail door glass lifter, one of the two pull wires 3 of the door glass lifter is connected to the motor 4, and the motor base plate includes a base plate body 1 and a clamping structure 2. The base plate body 1 is used to install the motor 4, and the clamping structure 2 is arranged on the base plate body 1 and is an integrated structure with the base plate body 1. The clamping structure 2 is used to clamp with the other of the two pull wires 3.
[0027] In addition to the motor base plate, the cable 3 and the motor 4, the double-guide rail door glass lifter usually also includes two guide rails 5 and sliders 6 respectively located on the two guide rails 5. The two guide rails 5 are spaced apart in the front and rear directions of the vehicle and extend roughly vertically. The slider 6 can slide up and down along the corresponding guide rails 5. The two cables 3 are cross-arranged so that the two cables 3 are respectively the first cable and the second cable. The two guide rails 5 are respectively the first guide rail and the second guide rail. One end of the first cable is fixedly connected to the slider 6 on the first guide rail, and the other end passes through the top pulley of the first guide rail and the bottom pulley of the second guide rail in turn and is fixedly connected to the slider 6 on the second guide rail. One end of the second cable is fixedly connected to the slider 6 on the second guide rail, and the other end After passing through the top pulley of the second guide rail and the bottom pulley of the first guide rail in sequence, the first pull wire is fixedly connected to the slider 6 on the first guide rail. The first pull wire can be wound on the winding drum, and the motor 4 can drive the winding drum to rotate. In the process of driving the winding drum to rotate, the motor 4 can reel in the first pull wire, for example, making the section of the first pull wire between the winding drum and the slider 6 of the second guide rail longer and the section of the first pull wire between the winding drum and the slider 6 of the first guide rail shorter. At this time, the first pull wire can pull the slider 6 on the first guide rail upward. During the process of the slider 6 on the first guide rail rising, it can pull the second pull wire, so that the second pull wire drives the slider 6 on the second guide rail to rise synchronously and straighten the section of the first pull wire between the winding drum and the slider 6 of the second guide rail. Since the window glass is fixedly connected to the sliders 6 on the two guide rails 5 respectively through the glass clamp, the slider 6 will drive the window glass to rise and fall as it rises and falls vertically along the guide rail 5.
[0028] The motor 4 is fixed on the seat plate body 1 , and the clamping structure 2 can adopt existing technology as long as it can achieve fixed limitation of the pull wire 3 .
[0029] In this embodiment, on the one hand, the seat plate body 1 of the motor seat plate can realize the function of an ordinary motor seat plate for fixing the motor 4. On the other hand, by providing a clamping structure 2 on the seat plate body 1, one of the pull wires 3 of the window lifter is clamped by the clamping structure 2, and the other pull wire 3 is connected to the motor 4 on the motor seat plate, so that the two crossed pull wires 3 are pressed toward the seat plate body 1, thereby limiting the two pull wires 3 and preventing them from shaking and hitting the window glass along the Y direction of the vehicle (the left and right directions of the vehicle) to produce abnormal noise; at the same time, compared with the existing solution in which the buckle and the motor seat plate are separately provided, integrating the clamping structure 2 with the seat plate body 1 can reduce the number of parts, reduce costs, and simplify the assembly process; in addition, the seat plate body 1 of the motor seat plate is usually fixed on the relevant structure of the vehicle door, which can further improve the fixing stability of the two pull wires 3.
[0030] Optionally, the clamping structure 2 and the seat plate body 1 are integrally injection molded.
[0031] In this embodiment, the selected injection molding material is added to the hopper of the injection molding machine. After that, the injection molding material is heated to make it into a molten state and injected into the mold to fill the cavity of the mold. After cooling and solidification, the required motor seat plate can be formed, realizing the integrated injection molding of the snap-fit structure 2 and the seat plate body 1. The molding process is simple and the processing cost is low.
[0032] In some other embodiments, compression molding, extrusion molding, etc. may also be used.
[0033] like Figure 2 and 3 As shown, optionally, the seat plate body 1 is partially bent to form a recessed portion 11 , and the clamping structure 2 is disposed in the recessed portion 11 .
[0034] In this embodiment, the seat plate body 1 can be roughly located in the XZ plane. Since the motor 4 is usually installed on the side of the seat plate body 1 facing the outside of the vehicle, the edge portion of the seat plate body 1 can be bent twice toward the outside of the vehicle to form an L-shaped recessed portion 11 on the inner side of the seat plate body 1. The protruding height of the recessed portion 11 toward the outside of the vehicle does not exceed the motor 4. In this way, installing the clip structure 2 in the recessed portion 11 can not only effectively reduce the overall space occupied by the door glass lifter in the Y direction of the vehicle, but also avoid the clip structure 2 protruding from the inner surface of the seat plate body 1 to interfere with related structures. Moreover, compared with the flat seat plate body 1, it can also increase the strength of the seat plate body 1 and improve the stability of the fixation of the motor 4 and the pull wire 3.
[0035] like Figure 4 As shown, optionally, a slot 21 matching the corresponding pull wire 3 is provided on the snap-in structure 2, and both ends of the slot 21 along its extension direction pass through the snap-in structure 2, and the inner wall of the slot 21 matches the shape of the outer peripheral wall of the corresponding pull wire 3.
[0036] In this embodiment, the slot 21 can be an arcuate slot to better match the circular outer wall of the cable 3. The slot 21 extends generally along the Z direction or is inclined relative to the Z direction, which is more consistent with the routing direction of the cable 3 and facilitates the cable's fixation. The slot 21 extends through the clamping structure 2 at both ends along its extension direction. In other words, the slot 21 has openings connected to the notch 211 at both ends along its extension direction. The cable 3 is inserted into the slot 21 through the notch 211 and can extend through the openings at both ends.
[0037] like Figure 4 As shown, optionally, the notch 211 of the slot 21 is provided with a guiding slope 212 to guide the corresponding pull wire 3 into the slot 21 .
[0038] In this embodiment, by providing a guiding slope 212 at the notch 211 of the slot 21 , the pull wire 3 can smoothly enter the slot 21 under the guidance of the guiding slope 212 , thereby improving the convenience of assembling the pull wire 3 .
[0039] Optionally, the clamping structure 2 is an elastic clamping structure. The clamping structure 2 is made of plastic and can be squeezed and deformed. The pull wire 3 is inserted into the clamping slot 21 from the notch 211 under the action of external squeezing force, and then the clamping slot 21 recovers its deformation to fix the pull wire 3.
[0040] In some embodiments, a wire passage 12 may be provided on the seat plate body 1 for the wire 3 connected to the motor 4 to pass through, and the clamping structure 2 and the wire passage 12 are located on the same side of the seat plate body 1. The wire passage 12 may extend along the Z direction or be tilted relative to the Z direction. By using the wire passage 12 to limit the position of the wire 3 connected to the motor 4, the shaking of the wire 3 can be reduced. Since the clamping structure 2 and the wire passage 12 are respectively used to limit and fix the two wires 3, by arranging the clamping structure 2 and the wire passage 12 on the same side of the seat plate body 1, such as the side away from the door glass, it is beneficial to increase the distance between the wire 3 and the door glass, thereby preventing the wire 3 from hitting the door glass.
[0041] like Figure 1-Figure 2 As shown, another embodiment of the present invention provides a vehicle door glass lifter, comprising a motor 4, two cross-arranged pull wires 3 and the above-mentioned motor base plate.
[0042] Specifically, the door glass lifter can also include guide rails 5 and sliders 6. The two guide rails 5 are spaced apart along the front and rear directions of the vehicle and extend roughly vertically. The two sliders 6 are respectively arranged on the corresponding guide rails 5 and can slide up and down along the guide rails 5. The two pull wires 3 are cross-arranged, so that the two pull wires 3 are respectively the first pull wire and the second pull wire. The two guide rails 5 are respectively the first guide rail and the second guide rail. One end of the first pull wire is fixedly connected to the slider 6 on the first guide rail, and the other end passes through the top pulley of the first guide rail and the bottom pulley of the second guide rail in turn, and is fixedly connected to the slider 6 on the second guide rail. One end of the second pull wire is fixedly connected to the slider 6 on the second guide rail, and the other end passes through the top pulley of the second guide rail in turn. The first pulley and the bottom pulley of the first guide rail are fixedly connected to the slider 6 on the first guide rail. The first cable can be wound on the cable drum, and the motor 4 can drive the cable drum to rotate. In the process of driving the cable drum to rotate, the motor 4 can reel in the first cable, for example, making the section of the first cable between the cable drum and the slider 6 of the second guide rail longer and the section of the first cable between the cable drum and the slider 6 of the first guide rail shorter. At this time, the first cable can pull the slider 6 on the first guide rail to rise. In the process of rising, the slider 6 on the first guide rail can pull the second cable, so that the second cable drives the slider 6 on the second guide rail to rise synchronously and straighten the section of the first cable between the cable drum and the slider 6 of the second guide rail. Since the window glass is fixedly connected to the sliders 6 on the two guide rails 5 respectively through the glass clamp, the slider 6 will drive the window glass to rise and fall as it rises and falls vertically along the guide rail 5.
[0043] The advantages of the door glass lifter compared to the prior art are the same as those of the motor base plate, and will not be described again.
[0044] Yet another embodiment of the present invention provides a vehicle door comprising a door body and the aforementioned door glass regulator, the door glass regulator being mounted within the door body. Specifically, the door body defines a door cavity, and the door glass regulator is mounted within the door cavity. The advantages of this vehicle door over the prior art are the same as those of the aforementioned door glass regulator, and their description will not be repeated.
[0045] Optionally, the vehicle door further comprises a door glass, which is located on the side of the motor base plate away from the clamping structure 2. That is, the door glass and the clamping structure 2 are respectively located on both sides of the base plate body 1, which is conducive to increasing the distance between the pull wire 3 and the door glass to avoid the two from making a clapping sound.
[0046] Another embodiment of the present invention provides a vehicle including the above-mentioned door glass regulator or the above-mentioned door. The advantages of the vehicle over the prior art are the same as those of the above-mentioned door glass regulator or the above-mentioned door, and are not described again.
[0047] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
