[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] According to one embodiment of the present invention, an electric glass lifting mechanism for an automobile and an automobile door are provided. The electric glass lifting mechanism for an automobile includes a mounting bracket, a guide rail, a movable block and an abutment seat. The automobile glass window can be connected to the movable block. The movable block can move on the guide rail under the drive of the driving member. The abutment seat can limit the movable block, so that in practice, the driving force applied by the driving member to the movable block can be prevented from being transmitted to the guide rail mud groove via the glass. Figure 1 and Figure 2 The figure further describes the automobile electric glass lifting mechanism and the automobile door in this embodiment.

[0022] Specifically, if Figure 1 and Figure 2 As shown, the electric glass lifting mechanism for automobile in this embodiment includes: a mounting bracket 10 , a guide rail 20 , a movable block 30 and an abutment seat 40 .

[0023] Among them, the guide rail 20 is set on the mounting bracket 10, and the guide rail 20 is extended along the height direction of the mounting bracket 10; the movable block 30 is slidably set on the guide rail 20, and the movable block 30 can move along the extension direction of the guide rail 20; the abutment seat 40 is set on the mounting bracket 10, and the abutment seat 40 is located at the top of the guide rail 20. The movable block 30 can abut against the abutment seat 40 during the process of moving upward along the guide rail 20.

[0024] For example, the mounting bracket 10 can be made of a metal material with a certain structural strength, for example, the mounting bracket 10 can be made of a sheet metal by stamping, etc. The mounting bracket 10 serves as a supporting structure of the entire mechanism, and can be fixed in the car door by means of bolts and other structures.

[0025] Exemplarily, the guide rail 20 is made of a metal material, and has a certain length, for example, the guide rail 20 can be a long L-shaped guide rail 20 or a T-shaped guide rail 20. The guide rail 20 extends along the height direction of the mounting bracket 10, that is, after the mounting bracket 10 is fixed to the car door, the guide rail 20 follows the mounting bracket 10 and extends substantially in the vertical direction.

[0026] Optionally, the guide rail 20 is fixed on the mounting bracket 10 by welding.

[0027] For example, the movable block 30 can be made of a non-metallic material, the movable block 30 is slidably connected to the guide rail 20, and the automobile glass window can be fixedly connected to the movable block 30. It can be understood that after the guide rail 20 is fixed to the automobile door following the mounting bracket 10, the movable block 30 can be driven by a driving member such as a motor to move in the vertical direction along the extension direction of the guide rail 20, so that the automobile glass window can move in the vertical direction.

[0028] For example, the abutment seat 40 can be made of an elastic rubber material or a metal material, the abutment seat 40 is fixedly connected to the mounting bracket 10, the abutment seat 40 is arranged on the top of the guide rail 20, and the abutment seat 40 can limit the movement of the movable block 30. It can be understood that after the mounting bracket 10 is fixed to the car door, when the movable block 30 moves upward in the vertical direction, the movable block 30 can abut against the abutment seat 40, and under the restriction of the abutment seat 40, the movable block 30 can be prevented from continuing to move upward.

[0029] In actual application scenarios, the automobile electric glass lifting mechanism in this embodiment can be fixedly installed in the automobile door by means of the mounting bracket 10, the automobile glass window can be fixedly connected to the movable block 30, and the driving parts such as the motor and the hydraulic cylinder can be connected to the movable block 30. When the window needs to be closed or opened, the driving part will drive the movable block 30 to move on the guide rail 20 according to the control signal, driving the automobile glass window to perform lifting and lowering movements, thereby realizing the closing or opening of the window.

[0030] When the car window needs to be completely closed, the driving member will drive the movable block 30 to move upward along the vertical direction on the guide rail 20. When the movable block 30 moves upward and abuts against the abutment seat 40, it means that the car glass window has risen to the top and the car glass window has entered the guide rail mud groove.

[0031] In the present embodiment, since the abutment seat 40 can limit the upward movement of the movable block 30, the driving force applied by the driving member to the movable block 30 will be transferred to the abutment seat 40. The abutment force applied by the automobile glass window to the guide rail mud groove after it rises into position can be greatly reduced. The guide rail mud groove will not be shifted under the abutment of the glass, nor will the gap between the mud groove and the outer column trim panel become larger. In addition, the shaking of the door frame caused by the excessive driving force applied by the driving member to the movable block 30 can be reduced.

[0032] Further, in one embodiment, Figure 1 As shown, the abutment seat 40 includes: a latch 41 and a rubber stopper 42 . The rubber stopper 42 is fixed to the mounting bracket 10 via the latch 41 . The movable block 30 can abut against the rubber stopper 42 during the process of moving upward along the guide rail 20 .

[0033] It can be understood that the rubber stopper 42 is made of a rubber material, which has a certain elasticity and can produce elastic deformation. One end of the latch 41 can be fixedly arranged on the mounting bracket 10, and the rubber stopper 42 can be fixed to the latch 41.

[0034] In actual use, after the driving member drives the movable block 30 to abut against the rubber stopper 42, the rubber stopper 42 can limit the movable block 30 from moving further upward. Moreover, since the rubber stopper 42 is elastic, it can absorb and buffer the impact force generated by the movable block 30 on the rubber stopper 42, and can also absorb the gap error between the top of the car window glass and the bottom of the guide rail mud groove to prevent water leakage.

[0035] Furthermore, in a specific embodiment, in order to achieve installation, the rubber stopper 42 has a mounting hole, the first end of the latch 41 is inserted into the mounting hole, and the second end is fixed to the mounting bracket 10 .

[0036] Exemplarily, the rubber stopper 42 may have a mounting hole extending through the thickness direction thereof, the first end of the latch 41 being inserted into the mounting hole, and the rubber stopper 42 can be sleeved on the latch 41 using the mounting hole, and the second end of the latch 41 is fixed to the mounting bracket 10 .

[0037] Furthermore, in order to ensure that the rubber stopper 42 can be effectively fixed on the mounting bracket 10, as shown in FIG. Figure 2 As shown, a limiting protrusion 411 is disposed at the first end of the latch 41 , and the limiting protrusion 411 protrudes outwardly along the radial direction of the latch 41 , and the rubber stopper 42 is located on the inner side of the limiting protrusion 411 facing the second end of the latch 41 .

[0038] For example, the limiting protrusion 411 can be fixedly provided on the side of the first end of the latch 41 in an integrally formed manner. During installation, the rubber stopper 42 is sleeved on the latch 41, and then the second end of the latch 41 is fixed to the mounting bracket 10 via the through hole on the mounting bracket 10. For example, the latch 41 can be fixed to the mounting bracket 10 by riveting. At this time, the rubber stopper 42 can be clamped between the limiting protrusion 411 and the mounting bracket 10 in the axial direction of the latch 41, so that it can be effectively fixed to the mounting bracket 10.

[0039] Further, in one embodiment, Figure 2 As shown, on the rubber stopper 42 , the thickness of the side of the mounting hole facing the movable block 30 is greater than the thickness of the other side of the mounting hole away from the movable block 30 .

[0040] It can be understood that the mounting hole can be an eccentric hole provided on the rubber stopper 42, that is, the mounting hole deviates from the center position of the rubber stopper 42. Figure 2 As shown, in the extension direction of the guide rail 20 , the thickness of the rubber stopper 42 at one side of the mounting hole facing the movable block 30 is greater than the thickness of the other side of the mounting hole away from the movable block 30 .

[0041] It can be understood that in the above-mentioned setting, after the latch 41 is fixed relative to the mounting bracket 10, the portion of the rubber stopper 42 on the side where the mounting hole faces the movable block 30 needs to bear the impact force applied to it by the movable block 30, while the portion on the side where the mounting hole faces away from the movable block 30 does not need to bear the external force. Based on this, by setting the portion of the rubber stopper 42 on the side where the mounting hole faces the movable block 30 to have a larger thickness, compared with a thinner thickness, this portion can more effectively buffer the impact force applied by the movable block 30 and can save space.

[0042] Further, in one embodiment, Figure 1As shown, the automobile electric glass lifting mechanism further includes a driving member, wherein the driving member includes a driving motor and a pull rope 51, wherein the driving motor is arranged on the mounting bracket 10, and the pull rope 51 is connected between the output end of the driving motor and the movable block 30, and the output end of the driving motor can pull the movable block 30 to move on the guide rail 20 during the rotation process.

[0043] It can be understood that the output end of the driving motor can rotate, one end of the pull rope 51 is connected to the driving motor, and the other end is connected to the movable block 30. During the rotation of the output end of the driving motor, the pull rope 51 can be wound around the output end, thereby pulling the movable block 30 to move on the guide rail 20.

[0044] In one embodiment, Figure 1 As shown, in order to ensure that the driving member can drive the movable block 30 to move upward in the vertical direction on the guide rail 20, the driving member also includes a roller 52, and the roller 52 is rotatably set on the mounting bracket 10. The roller 52 is located at the top of the guide rail 20. One end of the pull rope 51 is connected to the output end of the driving motor, and the other end passes over the roller 52 and then is connected to the movable block 30.

[0045] For example, the roller 52 may be rotatably disposed on the mounting bracket 10 via a rotation axis.

[0046] In actual use, during the process of retrieving the pull rope 51 at the output end of the driving motor, the roller 52 can support the pull rope 51 at the top of the guide rail 20 , so that the driving motor can effectively drive the movable block 30 to move upward on the guide rail 20 .

[0047] In addition, in order to drive the movable block 30 to move downward on the guide rail 20, the driving member can also include an additional pull rope, which is connected between the output end of the driving motor and the movable block 30, and the additional pull rope and the pull rope 51 are respectively connected to the opposite sides of the movable block 30.

[0048] Moreover, similarly, in order to ensure that the driving member can drive the movable block 30 to move downward in the vertical direction on the guide rail 20, the driving member also includes an additional roller 52, which is rotatably arranged on the mounting bracket 10, and the additional roller 52 is located at the bottom of the guide rail 20. One end of the additional pull rope is connected to the output end of the driving motor, and the other end is connected to the movable block 30 after passing over the additional roller 52.

[0049] Therefore, only one driving motor is needed to drive the movable block 30 to move in two opposite directions on the guide rail 20 through the pull rope 51 and the additional pull rope respectively.

[0050] For example, in one embodiment, when the output end of the driving motor rotates in a first direction, the pull rope 51 is wound around the output end, and the additional pull rope is released. At this time, the pull rope 51 can pull the movable block 30 to move upward on the guide rail 20. Conversely, when the output end of the driving motor rotates in a second direction opposite to the first direction, the additional pull rope is wound around the output end, and the pull rope 51 is released. At this time, the movable block 30 can be pulled downward on the guide rail 20 by the additional pull rope.

[0051] Further, in order to facilitate the installation and connection of automobile glass windows, such as Figure 1 As shown, the movable block 30 is provided with a mounting concave surface 31 for connecting the glass, and the number of the mounting concave surfaces 31 is two, and the two mounting concave surfaces 31 are respectively located on both sides of the guide rail 20 .

[0052] Exemplarily, the movable block 30 has an end face parallel to the extension direction of the guide rail 20, and a mounting concave surface 31 is provided on the end face, and the mounting concave surface 31 is sunken into the end face. Moreover, two mounting concave surfaces 31 are provided on the end face, and the two mounting concave surfaces 31 are respectively located on both sides of the guide rail 20. During actual installation, the bottom of the automobile glass window can be attached to and connected to the two mounting concave surfaces 31.

[0053] It can be understood that by providing two mounting concave surfaces 31 , the automobile glass window can be positioned through two connection points, and the positional displacement of the automobile glass window relative to the movable block 30 during the movement can be avoided.

[0054] At the same time, in order to effectively fix the automobile glass window, a through hole is also provided on the installation concave surface 31. During installation, external bolts can pass through the through hole and be fixedly connected to the automobile glass window, thereby enabling the automobile glass window to be effectively connected to the movable block 30.

[0055] In addition, as mentioned above, this embodiment also provides a car door, which is provided with the car electric glass lifting mechanism in the above embodiment.

[0056] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
