A sliding block for a flat car door window regulator

Abstract

This application discloses a slider for a flat-pane car door window regulator, relating to the technical field of window operation. It includes a slider body with a glass bracket snapped onto it. A rubber buffer is positioned between the glass bracket and the slider body, located on the slider body and abutting against the glass bracket. The end of the glass bracket furthest from the slider is fixed to the glass. When the glass rises to its highest position, the impact force is first transmitted to the glass bracket and then to the rubber buffer. The glass bracket, acting as an intermediate carrier, disperses some of the impact force, reduces the compressive strength on the rubber buffer, and minimizes the direct shearing action of the glass on the buffer. This prevents the rubber buffer from breaking due to shearing by the glass, thus avoiding the problem of abnormal noise caused by friction between the glass and the slider during window operation.

Description

Technical Field

[0001] This application relates to the technical field of car window lifting, and in particular to a slider for a flat car door window lifter. Background Technology

[0002] Flush doors, also known as level doors or zero-step doors, were first introduced by Honda in 2004 with the Legend, and further popularized by the Porsche Panamera in 2009. Since then, other models have followed suit, including the 2018 Lexus LS500 and the 2022 Land Rover Range Rover. Flush doors fall between framed and frameless doors, offering a stylish and attractive appearance, low wind resistance, and inexpensive window regulators. However, flush doors can only use single-rail window regulators.

[0003] Before installing car windows, a window regulator is pre-installed on the inside of the door. The window regulator includes a drive motor, guide rail, slider, and steel cable. The guide rail is installed on the inside of the door and is set along the height direction. The slider is slidably installed on the guide rail, and the steel cable is connected to the slider. The glass is clipped and fixed to the slider. The drive motor pulls the steel cable, which in turn pulls the slider up and down on the guide rail, thereby raising and lowering the glass. Usually, a rubber buffer is installed at the contact point between the glass and the slider. When the glass rises to its highest position, the glass is subjected to a large impact force, causing the glass to squeeze and impact the rubber buffer. After repeated squeezing and impact, the rubber buffer is easily sheared by the glass and breaks, causing abnormal noise due to friction between the glass and the slider during raising and lowering. Utility Model Content

[0004] To address the problem of rubber buffer components breaking due to shearing by the glass, causing abnormal noise due to friction between the glass and the slider during lifting, this application provides a slider for a flat car door window regulator.

[0005] This application provides a slider for a flat-pane car door window regulator, which adopts the following technical solution: A sliding block for a flat-pane car door window regulator includes a sliding block body, a glass bracket snapped onto the sliding block body, a rubber buffer between the glass bracket and the sliding block body, the rubber buffer being located on the sliding block body and abutting against the glass bracket; and the end of the glass bracket away from the sliding block being fixed to the glass.

[0006] By adopting the above technical solution, when the glass rises to its highest position, the impact force on the glass is first transferred to the glass bracket, and then to the rubber buffer. The glass bracket, acting as an intermediate carrier, can disperse some of the impact force, reduce the compressive strength on the rubber buffer, and decrease the direct shearing action of the glass on the buffer. This prevents the rubber buffer from breaking due to shearing by the glass, thus avoiding the problem of abnormal noise caused by friction between the glass and the slider during lifting.

[0007] Preferably, the edges of the contact portion between the glass bracket and the rubber buffer are rounded.

[0008] By adopting the above technical solution, the rounded corner design can prevent local stress concentration caused by the edge of the glass bracket on the rubber buffer, reduce the possibility of damage to the rubber buffer due to excessive local stress, extend the service life of the rubber buffer, ensure its long-term stable buffering effect, and further reduce the risk of abnormal noise.

[0009] Preferably, the glass bracket has a first slot at the end away from the slider, and the glass bracket is fixed to the glass through the first slot.

[0010] By adopting the above technical solution, the first slot makes the connection between the glass and the glass bracket more convenient and stable. The snap-fit ​​method can better adapt to the stress during the glass lifting process, reduce the relative shaking between the glass and the bracket, thereby reducing friction noise caused by shaking, and also facilitates the installation, replacement and maintenance of the glass.

[0011] Preferably, the glass bracket is integrally formed by injection molding.

[0012] By adopting the above technical solutions, the injection molding process ensures the consistency and stability of the overall structure of the glass bracket, reduces gaps or weak connections caused by component splicing, improves the structural strength and load-bearing capacity of the glass bracket, facilitates mass production, improves production efficiency, and reduces production costs. At the same time, the one-piece molding structure can reduce assembly errors and ensure the accuracy of the fit with the glass and slider.

[0013] Preferably, the slider has a second slot, the end of the glass bracket away from the glass is inserted into the second slot, and the rubber buffer is located in the second slot and supports the glass bracket.

[0014] By adopting the above technical solution, the second slot positions and guides the glass bracket, ensuring accurate relative positioning between the glass bracket and the slider, reducing offset during glass lifting and lowering, and making glass lifting and lowering smoother. Simultaneously, the rubber buffer, located within the slot and supporting the glass bracket, provides more stable cushioning, improving the reliability of the cushioning effect and preventing the buffer from failing due to unstable positioning.

[0015] Preferably, the glass bracket has a mounting hole at one end near the slider, and the slider has a hook that engages with the mounting hole to fix the glass bracket on the slider.

[0016] By adopting the above technical solution, the glass bracket is fixed on the slider by engaging with the mounting hole, which further enhances the firmness of the connection between the glass bracket and the slider, ensuring that the two will not easily separate during the glass lifting process and improving the stability of the structure.

[0017] Preferably, a rubber buffer is also provided between the hook and the glass bracket.

[0018] By adopting the above technical solution, the rubber buffer forms a buffer at the contact point between the hook and the glass bracket, reducing friction and impact caused by relative movement or vibration between the two, and further reducing the possibility of abnormal noise; at the same time, the rubber buffer can protect the contact point between the hook and the glass bracket, reduce wear, extend the service life of the hook, and improve the durability of the overall structure.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. When the glass rises to its highest position, the impact force on the glass is first transmitted to the glass bracket, and then to the rubber buffer. The glass bracket, as an intermediate carrier, can disperse some of the impact force, reduce the compressive strength of the rubber buffer, reduce the direct shearing action of the glass on the buffer, and prevent the rubber buffer from breaking due to shearing by the glass, which would cause abnormal noise due to contact and friction between the glass and the slider during lifting and lowering. 2. The edges of the contact area between the glass bracket and the rubber buffer are rounded. The rounded corner design can prevent the glass bracket edge from causing local stress concentration on the rubber buffer, reduce the possibility of damage to the rubber buffer due to excessive local stress, extend the service life of the rubber buffer, ensure its long-term stable buffering effect, and further reduce the risk of abnormal noise. 3. The glass bracket is fixed to the slider by engaging with the mounting holes, further enhancing the connection between the glass bracket and the slider and ensuring that they will not easily separate during glass lifting, thus improving structural stability. The rubber buffer forms a cushion at the contact point between the hook and the glass bracket, reducing friction and impact caused by relative movement or vibration, further reducing the possibility of abnormal noise. At the same time, the rubber buffer protects the contact point between the hook and the glass bracket, reduces wear, extends the service life of the hook, and improves the overall durability of the structure.

[0022] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0023] This application discloses a slider for a window regulator in a flat car door.

[0024] refer to Figure 1 A sliding block for a glass lifter 7 for a flat car door includes a slider body 1 and a glass bracket 2. The glass bracket 2 is mounted on the slider body 1, and the end of the glass bracket 2 away from the slider is used to fix the glass 7.

[0025] The glass bracket 2 has a first slot 3 at the end away from the slider. The glass 7 is inserted into the first slot 3 and locked in place with the glass bracket 2. The first slot 3 makes the connection between the glass 7 and the glass bracket 2 more convenient and stable. The locking method can better adapt to the force situation during the lifting and lowering of the glass 7, reduce the relative shaking between the glass 7 and the bracket, thereby reducing friction noise caused by shaking. It also facilitates the installation, replacement and maintenance of the glass 7.

[0026] refer to Figure 2 and Figure 3 The slider body 1 has a second slot 4 at one end near the glass bracket 2. The glass bracket 2 is inserted into the second slot 4. A rubber buffer 5 is fixed in the second slot 4 to support the glass bracket 2. After the glass bracket 2 is inserted into the second slot 4, it abuts against the rubber buffer 5. The edge of the part of the glass bracket 2 that contacts the rubber buffer 5 is processed into a rounded corner 22. The rounded corner 22 design can prevent the edge of the glass bracket 2 from causing local stress concentration on the rubber buffer 5, reduce the possibility of the rubber buffer 5 breaking due to excessive local stress, extend the service life of the rubber buffer 5, ensure its long-term stable buffering effect, and further reduce the risk of abnormal noise.

[0027] A mounting hole 21 is provided at one end of the glass bracket 2 near the slider body 1. A hook 6 is integrally formed on the side wall of the second slot 4 of the slider body 1. The hook 6 has a certain elasticity. When the glass bracket 2 is inserted into the second slot 4, the hook 6 cooperates with the mounting hole 21 to fix the glass bracket 2 on the slider, which enhances the installation stability of the glass bracket 2. A rubber buffer 5 is also placed between the hook 6 and the glass bracket 2. The glass bracket 2 also abuts against the rubber buffer 5 on the hook 6. The rubber buffer 5 forms a buffer at the contact point between the hook 6 and the glass bracket 2, reducing the friction and impact caused by relative movement or vibration between the two, and further reducing the possibility of abnormal noise. At the same time, the rubber buffer 5 can protect the contact point between the hook 6 and the glass bracket 2, reduce wear, extend the service life of the hook 6, and improve the durability of the overall structure.

[0028] In this embodiment, the glass bracket 2 is integrally formed by injection molding. The injection molding process ensures the consistency and stability of the overall structure of the glass bracket 2, reduces gaps or weak connections caused by component splicing, improves the structural strength and load-bearing capacity of the glass bracket 2, facilitates mass production, improves production efficiency, and reduces production costs. At the same time, the integrally formed structure can reduce assembly errors and ensure the accuracy of the fit with the glass 7 and the slider.

[0029] The implementation principle of this application embodiment is as follows: when the glass 7 rises to the highest position, the impact force on the glass 7 is first transmitted to the glass bracket 2, and then to the rubber buffer 5 on the slider; the glass bracket 2, as an intermediate carrier, can disperse part of the impact force; the rubber buffer 5 on the hook 6 can also alleviate part of the impact force, reduce the compressive strength of the rubber buffer 5, thereby reducing the direct shearing action of the glass 7 on the buffer, preventing the rubber buffer 5 from being sheared and broken by the glass 7, which would cause the glass 7 to rub against the slider during lifting and lowering and produce abnormal noise.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
