When it is necessary to raise or lower the car door glass, the support block can be separated from the car door glass to prevent abnormal noise caused by the contact friction between the car door glass and the support block during raising or lowering.

Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, specifically to a frameless door glass anti-vibration device, a door, and a vehicle. Background Technology

[0002] Currently, car doors mainly include framed doors and frameless doors. Frameless doors, due to their stylish and high-end appearance, are increasingly used in high-end models. However, when closing a frameless door with the glass half-lowered, the glass, lacking a frame support and operating in a cantilevered structure, is prone to vibration, resulting in a poor closing experience for the user. Utility Model Content

[0003] The present invention aims to solve the technical problem that frameless car doors are prone to vibration when the door is closed in a half-lowered state.

[0004] In a first aspect, this utility model provides a frameless car door glass anti-vibration device, including a support assembly. The support assembly is used to be installed inside the frameless car door body and located on one side of the car door glass. The support assembly includes a push-out mechanism and a support block. The push-out mechanism is used to be installed inside the frameless car door body and located on one side of the car door glass. One end of the push-out mechanism is drivenly connected to the support block and is used to drive the support block to move toward or away from the car door glass, so that the support block abuts or separates from the car door glass.

[0005] Optionally, the frameless door glass anti-vibration device further includes a speed detection mechanism for detecting the closing speed of the frameless door body. The speed detection mechanism is signal-connected to the ejection mechanism, which is configured to drive the support block to move toward the door glass to abut against it when the speed detection mechanism detects that the closing speed of the frameless door body is greater than a preset value.

[0006] Optionally, the ejection mechanism includes a rotary motor and a transmission rod. The rotary motor is driven and connected to the transmission rod. The support block is sleeved on the transmission rod and threadedly connected to the transmission rod. The support block is used for sliding connection with the frameless door body.

[0007] Optionally, the support components are provided in multiple ways, and the ejection mechanisms of the multiple support components are used to eject or retract synchronously.

[0008] Secondly, this utility model proposes a car door, including a frameless car door body, a car door glass and the aforementioned frameless car door glass anti-vibration device, wherein one end of the car door glass extends into the interior of the frameless car door body and is used for lifting and lowering relative to the frameless car door body, and the support component of the frameless car door glass anti-vibration device is installed inside the frameless car door body.

[0009] Optionally, the door also includes a window regulator rail, which is installed inside the frameless door body. The door glass is movably mounted on the window regulator rail, and the support assembly is installed on the window regulator rail.

[0010] Optionally, the support assembly is located at the end of the window lifter guide rail facing upwards towards the vehicle.

[0011] Optionally, two glass lifter guide rails and two support assemblies are provided, and the two support assemblies are respectively installed on the corresponding glass lifter guide rails.

[0012] Optionally, the door also includes a water-cutting sealing strip and a glass clamping block. The door glass is sealed to the end of the frameless door body facing upwards via the water-cutting sealing strip. The glass clamping block is movably mounted on the window regulator guide rail and is used to clamp the door glass.

[0013] Thirdly, this utility model proposes a vehicle including the aforementioned door.

[0014] The frameless door glass anti-shake device, door, and vehicle of this utility model have at least the following advantages compared to related technologies:

[0015] The lower end of the door glass typically extends vertically into the frameless door body. By installing the support assembly of the frameless door glass anti-vibration device inside the frameless door body and located on one side of the door glass, the ejection mechanism of the support assembly is driven by the support block. The ejection mechanism can eject along the left and right directions of the vehicle to drive the support block to move towards or away from the door glass, thereby achieving contact or separation between the support block and the door glass. When the door glass is lowered, such as in a half-lowered state, the support block can contact the door glass, providing support force to prevent vibration and improving the user's door-closing experience. Compared to solutions that directly increase the clamping force of the water-cooled sealing strip on the door glass, this application allows the support block to separate from the door glass when it is necessary to raise or lower the door glass, preventing abnormal noise caused by contact friction between the door glass and the support block during raising or lowering, and ensuring smooth raising and lowering of the door glass.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fitting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] In addition, it should be noted that in the description of this utility model, the terms and nouns in each embodiment, such as "upper," "lower," "front," and "rear," which indicate the location, are only used to simplify the description of the positional relationship based on the accompanying drawings. They do not mean that the components and devices referred to must be operated in accordance with the specific location and limited operation, method, and structure in the specification. Such directional terms do not constitute a limitation on this utility model.

[0028] This paper establishes a coordinate system XYZ, where the X-axis represents the vehicle's front-to-back direction, with the positive X-axis pointing forward and the negative X-axis pointing backward; the Y-axis represents the vehicle's left-to-right direction, with the positive Y-axis pointing to the left and the negative Y-axis pointing to the right; and the Z-axis represents the vehicle's vertical direction, with the positive Z-axis pointing upward and the negative Z-axis pointing downward. It should be noted that the aforementioned Z-axis representation is merely for ease of description and simplification, and does not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown in the figure, a frameless car door glass anti-vibration device according to an embodiment of the present invention includes a support assembly 1. The support assembly 1 is used to be installed inside the frameless car door body 4 and located on one side of the car door glass 5. The support assembly 1 includes an ejection mechanism 11 and a support block 12. One end of the ejection mechanism 11 is drivenly connected to the support block 12 and is used to drive the support block 12 to move toward or away from the car door glass 5, so that the support block 12 abuts against or separates from the car door glass 5.

[0030] Specifically, the frameless door body 4 may include an inner door panel structure and an outer door panel structure that are arranged opposite to each other and installed together. The support component 1 is installed inside the frameless door body 4, that is, between the inner door panel structure and the outer door panel structure. The ejection mechanism 11 of the support component 1 adopts conventional technology and can be fixedly installed on the inner door panel structure and / or the outer door panel structure. The lower end of the door glass 5 extends vertically into the interior of the frameless door body 4. The door glass 5 is approximately located in the XZ plane. The thickness direction of the door glass 5 is the direction shown by the Y axis. The ejection mechanism 11 is located on one side of the door glass 5 along its thickness direction. The ejection mechanism 11 can be ejected or retracted along the direction shown by the Y axis. The ejection mechanism 11 is drivenly connected to the support block 12.

[0031] In this embodiment, the lower end of the door glass 5 typically extends vertically into the interior of the frameless door body 4. The support assembly 1 of the frameless door glass anti-vibration device is installed inside the frameless door body 4 and located on one side of the door glass 5. The ejection mechanism 11 of the support assembly 1 is drivenly connected to the support block 12. The ejection mechanism 11 can eject along the left-right direction of the vehicle to drive the support block 12 to move towards or away from the door glass 5, thereby achieving contact or separation between the support block 12 and the door glass 5. When the door glass 5 descends, such as... When the car door is closed in the half-lowered state, the support block 12 of the support assembly 1 can abut against the door glass 5, and the support block 12 can provide support for the door glass 5 to prevent it from vibrating and improve the user's door closing experience. Compared with the solution of directly increasing the clamping force of the water-cutting sealing strip 7 on the door glass 5, in this embodiment, when it is necessary to raise or lower the door glass 5, the support block 12 of the support assembly 1 can be separated from the door glass 5, so as to prevent the door glass 5 from making abnormal noise when raising or lowering due to contact friction with the support block 12, and ensure the smooth raising and lowering of the door glass 5.

[0032] like Figure 2 and Figure 7 As shown, optionally, the frameless door glass anti-vibration device further includes a speed detection mechanism 2, which is used to detect the closing speed of the frameless door body 4. The speed detection mechanism 2 is signal-connected to the ejection mechanism 11. The ejection mechanism 11 is configured to drive the support block 12 to move toward the door glass 5 to abut against the door glass 5 when the speed detection mechanism 2 detects that the closing speed of the frameless door body 4 is greater than a preset value.

[0033] Specifically, the frameless door glass anti-vibration device also includes a controller 3, which can be designed separately or its functions can be directly integrated into the vehicle's existing control module; the speed detection mechanism 2 and the ejection mechanism 11 can be connected to the controller 3 by signal respectively.

[0034] In use, the speed detection mechanism 2 can detect the actual closing speed of the frameless door body 4. The speed detection mechanism 2 sends the measured speed signal to the controller 3. The controller 3 compares the received speed signal with the preset value. If the actual measured speed signal is greater than the preset value, it means that the closing force is too large. At this time, the control ejection mechanism 11 pushes out the support block 12. The support block 12 abuts against the door glass 5 and provides support force to the door glass 5 to prevent the door glass 5 from shaking. If the actual measured speed signal is less than or equal to the preset value, it means that the closing force is small. Even if the door glass 5 is not supported by the support block 12, the door glass 5 will not shake when the door is closed. At this time, the control ejection mechanism 11 drives the support block 12 to retract, and the support block 12 separates from the door glass 5, that is, the support block 12 is not needed to support the door glass 5.

[0035] In this way, by setting the speed detection mechanism 2, the timing of the support block 12 abutting against the door glass 5 can be controlled. For example, the support block 12 can only abut against the door glass 5 when the closing speed of the frameless door body 4 is detected to be large. When the closing speed of the frameless door body 4 is small or during the rest of the time except for the closing time of the door, the support block 12 can remain separated from the door glass 5 to ensure that the door glass 5 can be raised and lowered smoothly.

[0036] Here, the preset value can be determined based on the closing speed at which the door glass 5 just begins to shake, such as a preset value of 1.5m / s.

[0037] It should be noted that the speed detection mechanism 2 can use a speed sensor that directly measures the rotational speed of the frameless door body 4, making the measurement more direct and efficient. The speed sensor can be an optical speed sensor, a magnetoelectric / Hall sensor, etc. Of course, in some cases, the speed detection mechanism 2 can also be an ultrasonic sensor, a rotary encoder, etc., that indirectly measures the rotational speed of the frameless door body 4.

[0038] Depending on the type of speed detection mechanism 2, it can be installed in different locations such as the frameless door body 4, the side panel of the vehicle body, etc. For example, when using a Hall sensor, the Hall sensor can be installed at the end of the frameless door body 4 near the rear of the vehicle, that is, away from the end where the frameless door body 4 is hinged to the side panel of the vehicle body; when using an ultrasonic sensor, it can be installed on the side panel of the vehicle body; when using a rotary encoder, it can be installed at the hinge point between the frameless door body 4 and the side panel of the vehicle body.

[0039] Optionally, multiple support components 1 are provided, and the ejection mechanisms 11 of the multiple support components 1 are used to eject or retract synchronously. When the door glass 5 is lowered and the door needs to be closed, the ejection mechanisms 11 of the multiple support components 1 can eject the corresponding support blocks 12 respectively, so that the multiple support components 1 can simultaneously apply a supporting force to the door glass 5 to ensure the support stability of the door glass 5; when the door glass 5 needs to be raised or lowered, the ejection mechanisms 11 of the multiple support components 1 can retract the corresponding support blocks 12 respectively to avoid the support components 1 interfering with the raising or lowering of the door glass 5.

[0040] Optionally, the ejection mechanism 11 includes a rotary motor 111 and a transmission rod 112. The rotary motor 111 is driven by the transmission rod 112. A support block 12 is sleeved on the transmission rod 112 and threadedly connected to it. The support block 12 can be slidably connected to the frameless door body 4 to restrict its rotation, allowing it to move only in the direction of approaching or moving away from the door glass 5 under the drive of the transmission rod 112. For example, the support block 12 can be slidably connected to related components within the frameless door body 4, such as the window regulator guide rail 6, in the left-right direction. Thus, when the rotary motor 111 drives the transmission rod 112 to rotate, the transmission rod 112 can drive the support block 12 to move left and right, thereby achieving the ejection and retraction of the support block 12. The ejection mechanism 11 adopts a structure combining the rotary motor 111 and the transmission rod 112, which provides stable transmission, occupies less space, and is easy to arrange.

[0041] Of course, the ejection mechanism 11 can also adopt other structural forms, such as a cylinder or hydraulic cylinder, whose piston rod is connected to the support block 12, and the extension and retraction of the piston rod is used to realize the ejection and retraction of the support block 12.

[0042] Here, the support block 12 can be made of a flexible material to prevent scratching the door glass 5 when it comes into contact with it. The door glass 5 is usually a curved structure, so the end of the support block 12 facing the door glass 5 can be set to an arc surface that matches the curvature of the door glass 5. This allows the support block 12 to better support the door glass 5 under the pushing action of the ejection mechanism 11, preventing the door glass 5 from shaking.

[0043] like Figures 1-2 As shown, another embodiment of this utility model proposes a car door, including a frameless door body 4, a door glass 5, and the aforementioned frameless door glass anti-vibration device. One end of the door glass 5 extends into the interior of the frameless door body 4 and is used for lifting and lowering relative to the frameless door body 4. The support component 1 of the frameless door glass anti-vibration device is installed inside the frameless door body 4. The advantages of this car door compared to related technologies are the same as those of the aforementioned frameless door glass anti-vibration device, and will not be repeated.

[0044] like Figures 1-3 As shown, optionally, the door also includes a window regulator rail 6, which is installed inside the frameless door body 4. The door glass 5 is movably mounted on the window regulator rail 6, and the support assembly 1 is installed on the window regulator rail 6.

[0045] Specifically, the window regulator guide rail 6 is fixed inside the frameless door body 4 and extends roughly along the Z direction, i.e., vertically. The door glass 5 is movably mounted on the window regulator guide rail 6 and moves up and down relative to the window regulator guide rail 6 to realize the lifting and lowering of the door glass 5.

[0046] By installing the support component 1 of the frameless door glass anti-vibration device on the glass regulator guide rail 6, the support component 1 and the glass regulator guide rail 6 are integrated. Compared with the solution of installing the support component 1 on the frameless door body 4, the integration of the glass regulator is significantly improved, which is more conducive to development.

[0047] like Figures 2-3 As shown, optionally, the support assembly 1 is located at one end of the window lifter guide rail 6 facing upwards from the vehicle.

[0048] Specifically, when the door glass 5 is lowered, the upper end of the door glass 5 extends out of the frameless door body 4 in a cantilever structure, which is prone to vibration. By installing the support component 1 of the frameless door glass anti-vibration device on the end of the window regulator guide rail 6 facing the vehicle, the support component 1 is closer to the upper end of the door glass 5. When the ejection mechanism 11 ejects the support block 12 to abut against the door glass 5, the support block 12 can provide more stable support for the upper end of the door glass 5, thus preventing the door glass 5 from vibrating when the door is closed.

[0049] like Figures 2-3 As shown, optionally, two glass lifter guide rails 6 and two support components 1 are provided, and the two support components 1 are respectively installed on the corresponding glass lifter guide rails 6.

[0050] Specifically, each frameless door body 4 may be provided with two window regulator rails 6 inside. The two window regulator rails 6 are spaced apart along the front and rear direction of the vehicle. The door glass 5 is moved and set on the two window regulator rails 6. By setting two window regulator rails 6, the lifting stability of the door glass 5 can be ensured.

[0051] There are two support components 1. The two support components 1 are respectively installed on the corresponding window regulator guide rail 6. That is, the two window regulator guide rails 6 are respectively equipped with corresponding support components 1. The support blocks 12 of the two support components 1 can be pushed out by the corresponding push-out mechanism 11 at the same time, so as to support both ends of the door glass 5 and ensure the support stability of the door glass 5.

[0052] like Figures 1-5As shown, optionally, the door also includes a water-cutting sealing strip 7 and a glass clamping block 8. The door glass 5 is sealed to the end of the frameless door body 4 facing upwards of the vehicle through the water-cutting sealing strip 7. The glass clamping block 8 is movably installed on the glass regulator guide rail 6 and is used to clamp the door glass 5.

[0053] Specifically, the water-cutting sealing strip 7 is installed on the upper edge of the frameless door body 4, including an outer water-cutting sealing strip and an inner water-cutting sealing strip. The door glass 5 passes between the outer water-cutting sealing strip and the inner water-cutting sealing strip to achieve a sealed assembly between the door glass 5 and the frameless door body 4, preventing rainwater and impurities from entering the frameless door body 4. The glass clamp 8 can clamp the door glass 5 and move along the glass regulator guide rail 6 to achieve smooth lifting and lowering of the door glass 5.

[0054] In addition, when the door glass 5 is lowered and the frameless door body 4 is closed, the door glass 5 can be further prevented from vibrating by using the support component 1 of the frameless door glass anti-vibration device to support the door glass 5, and the water-cutting sealing strip 7 and glass clamp 8 to clamp the door glass 5.

[0055] Thirdly, in another embodiment of this utility model, a vehicle is provided, including the aforementioned door. The advantages of this vehicle compared to related technologies are the same as those of the aforementioned door, and will not be repeated here.

[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
