Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicles, and particularly relates to sliding windows and vehicles. Background Technology
[0002] With the rapid development of the automotive industry, the types and uses of automobiles are constantly improving and increasing. Car windows are an indispensable and important component of automobiles, and sliding window structures are widely used in medium and large buses. A glass sliding window is a device that allows switching between a closed and open state. A glass sliding window generally consists of a fixed glass pane and a movable glass pane that can slide relative to the fixed glass pane.
[0003] Sliding windows in cars are typically used on the side windows. Due to the limited space inside a car, passengers need to stretch their arms or twist their bodies to reach the window handle, and the direction of force is obstructed by the door trim panel. For example, rear passengers need to bend over to push the window, which can easily lead to physical collisions with the seat or door, making operation inconvenient. Furthermore, existing sliding windows require cutting a piece of glass to fit into the frame, then molding the glass and frame together in a mold, leaving a gap between the glass and the frame to form the window, and then sliding another piece of glass onto the frame. This process is cumbersome and increases manufacturing costs. Utility Model Content
[0004] The purpose of this application is to provide a sliding window that addresses the issues of improving the ease of use of sliding windows, reducing manufacturing costs, and improving the sealing performance of sliding windows.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, a sliding window is provided, comprising a fixed glass having a window area, a sliding glass slidably connected to the fixed glass along a preset direction, and a drive structure disposed on the fixed glass. The window area extends through the fixed glass, the sliding glass is connected to the output end of the drive structure, and the drive structure is used to drive the sliding glass to slide relative to the fixed glass along the preset direction to close the window area, or to overlap with the fixed glass to at least partially open the window area. A flexible sealing element is disposed on the surface of the sliding glass facing the fixed glass, the flexible sealing element being made of a flexible material, and the flexible sealing element abutting against the fixed glass.
[0007] In some embodiments, the drive structure includes a transmission member and a power structure for driving the transmission member to move along the preset direction, the transmission member being connected to the sliding glass.
[0008] In some embodiments, the transmission component is a synchronous belt, the power structure includes a synchronous pulley and a driver that drives the synchronous pulley to rotate, the synchronous belt is wound around the synchronous pulley, the synchronous belt includes a connecting segment extending along the preset direction, and the sliding glass is connected to the connecting segment.
[0009] In some embodiments, the drive structure further includes a connector, one end of which is connected to the timing belt, and the other end of which is connected to the surface of the sliding glass opposite to the fixed glass.
[0010] In some embodiments, the sliding window further includes a guide rail connected to the fixed glass and extending along the preset direction. Two guide rails are spaced apart, and each guide rail is provided with a sliding groove. The two ends of the sliding glass are respectively slidably connected to the two sliding grooves.
[0011] In some embodiments, the sliding window further includes a central column, which is connected to the edge of the sliding glass along the preset direction. The two ends of the central column are respectively adjacent to the two guide rails. The flexible sealing element is provided on the surface of the central column facing the fixed glass, and the flexible sealing element extends along the length direction of the central column.
[0012] In some embodiments, the central column has a mounting groove on the side facing the sliding glass, the edge of the sliding glass is inserted into the mounting groove, and a sealing rubber is sandwiched between the sliding glass and the inner wall of the mounting groove.
[0013] In some embodiments, a sealing strip is embedded in the slide groove, the sealing strip extends in the same direction as the slide groove, and a limiting groove is provided on the side of the sealing strip facing the sliding glass, and the edge of the sliding glass is inserted into the limiting groove.
[0014] In some embodiments, the two ends of the slide are respectively provided with plugs for preventing the sliding glass from sliding out of the slide.
[0015] Secondly, a vehicle is provided that includes the sliding window described above.
[0016] The beneficial effects of this application are as follows: The sliding window provided in this application, when in use, allows the sliding glass to slide back and forth along a preset direction via a drive structure, thus closing or opening the window area. This enables the opening and closing of the car sliding window without manual force, allowing operation even when space or physical movement is restricted, thereby improving ease of use. Furthermore, during manufacturing, the window area only needs to be cut out of the fixed glass, and then the sliding glass and fixed glass can be slidably installed, eliminating the need for injection molding and effectively reducing manufacturing costs. Additionally, by setting a flexible seal, if rainwater adheres to the surface of the fixed glass, the flexible seal can effectively sweep away the rainwater, providing both waterproofing and dustproofing. This effectively prevents dust, moisture, etc., from entering the gap between the sliding glass and the fixed glass, thereby improving the sealing performance of the sliding window.

[0030] Please see Figures 1 to 6 This application provides a sliding window, including a fixed glass 10 with a window area 11, a sliding glass 20 slidably connected to the fixed glass 10 along a preset direction a, and a driving structure 30 disposed on the fixed glass 10. The window area 11 extends through the fixed glass 10. The sliding glass 20 is connected to the output end of the driving structure 30. The driving structure 30 is used to drive the sliding glass 20 to slide relative to the fixed glass 10 along the preset direction a to close the window area 11, or to stack with the fixed glass 10 to at least partially open the window area 11. A flexible sealing element 50 is disposed on the surface of the sliding glass 20 facing the fixed glass 10. The flexible sealing element 50 is made of a flexible material and abuts against the fixed glass 10.
[0031] Understandably, the sliding glass 20 and the fixed glass 10 are spaced apart along the thickness direction of the sliding glass 20, so the sliding of the sliding glass 20 will not interfere with the fixed glass 10 (e.g., Figure 1 The position indicated by the dashed line is the position of the sliding glass 20 after it has been slid. When the sliding glass 20 moves to the closed window area 11, the sliding window is in the closed state; and when the sliding glass 20 moves to overlap with the fixed glass 10 so that at least part of the window area 11 is open, the sliding window is in the open state.
[0032] The sliding window provided in this embodiment allows the sliding glass 20 to reciprocate along a preset direction a via the drive structure 30, thereby closing or opening the window area 11. This enables the opening and closing of the car sliding window without manual force, allowing operation even when space or physical movement is restricted, thus improving ease of use. Furthermore, during manufacturing, the window area 11 is simply cut out of the fixed glass 10, and the sliding glass 20 is then slidably installed onto the fixed glass 10, eliminating the need for injection molding and effectively reducing manufacturing costs. In addition, the flexible sealing element 50 effectively removes rainwater adhering to the surface of the fixed glass 10, providing both waterproofing and dustproofing. This effectively prevents dust and moisture from entering the gap between the sliding glass 20 and the fixed glass 10, thereby improving the sealing performance of the sliding window.
[0033] It should be noted that in this embodiment, a through hole can be drilled in the fixed glass 10 as the window area 11. The fixed glass 10 serves as the main frame, requiring only a partial cutout. The movement range of the sliding glass 20 is limited to the cutout area, significantly reducing the space occupied inside the car door. This is especially suitable for models with strict limitations on door thickness or interior layout, avoiding the installation difficulties caused by excessively long tracks in traditional sliding windows. Furthermore, the sliding glass 20 can directly fit against the cutout edge of the fixed glass 10, reducing air leakage and water seepage problems caused by track gaps in traditional sliding windows. In addition, the fixed glass 10 is not cut into an independent window frame, preserving the mechanical properties of the entire piece of glass, and its impact resistance is superior to that of traditional split sliding windows.
[0034] In some embodiments, the drive structure 30 includes a transmission member 32 and a power structure 31 for driving the transmission member 32 to move along a preset direction a. The transmission member 32 is connected to the sliding glass 20. Understandably, the transmission member 32 is connected to the output end of the power structure 31, and the power structure 31 drives the transmission member 32 to move along the preset direction a. Since the transmission member 32 is connected to the sliding glass 20, the transmission member 32 can drive the sliding glass 20 to move synchronously.
[0035] By connecting the power transmission component to the sliding glass 20, the rotational or linear power output by the power structure 31 is converted into the precise translational motion required by the sliding glass 20 through the transmission component 32. This avoids energy loss caused by mismatch between the power direction and load requirements, and prevents the power structure 31 from being directly connected to the sliding glass 20. This also prevents the power structure 31 from stalling or losing its steps due to load fluctuations in the sliding glass 20 (such as sudden changes in resistance). The transmission component 32 can buffer impacts and maintain the straightness of the motion trajectory, preventing the sliding glass 20 from deviating or jamming. In addition, the transmission component 32 can be arranged around the complex internal structure of the car door (such as wiring harnesses and speakers), avoiding restrictions on the installation position of the power structure 31.
[0036] Optionally, the transmission component 32 and the driver 311 can be packaged as independent modules to easily adapt to different sized windows. Only the length of the transmission component 32 needs to be adjusted, without redesigning the power structure 31. Of course, the transmission component 32 can also be used as an independent component, which can be replaced separately when damaged, without disassembling the entire power structure 31 or the glass assembly, thereby helping to reduce maintenance costs and improve the convenience of maintenance and adjustment.
[0037] In some embodiments, a single power structure 31 may be provided, that is, only one power structure 31 may be provided, and the transmission component 32 may be connected to multiple sliding glass 20, thereby synchronously driving multiple sliding glass 20 through the transmission component 32 to ensure the consistency of opening and closing actions and realize multi-window linkage control.
[0038] In some embodiments, the transmission component 32 is a synchronous belt 321, and the power structure 31 includes a synchronous pulley 312 and a driver 311 that drives the synchronous pulley 312 to rotate. The synchronous belt 321 is wound around the synchronous pulley 312 and includes a connecting section 3211 extending along a preset direction a. The sliding glass 20 is connected to the connecting section 3211. The driver 311 can drive the synchronous pulley 312 to rotate, thereby causing the connecting section 3211 of the synchronous belt 321 to move, and the sliding glass 20 moves synchronously with the connecting section 3211. By setting the synchronous belt 321, friction noise is significantly reduced during operation, meeting the stringent NVH (noise, vibration, and harshness) requirements of automotive cabins. Furthermore, the synchronous belt 321 can bypass complex structures inside the door, such as speakers, anti-collision beams, or wiring harnesses, and achieve multi-angle steering through the synchronous pulley 312, adapting to narrow or irregular spaces inside the vehicle. In addition, the synchronous belt 321 is lightweight, which helps to reduce the weight of the door assembly and improve vehicle energy efficiency.
[0039] Specifically, the drive wheel includes a driving wheel and a driven wheel. The driving wheel is connected to the output shaft of the driver 311. The driven wheel is spaced apart from the driving wheel and the axis of the driving wheel is parallel to the axis of the driven wheel. The two ends of the synchronous belt 321 are respectively wound around the driving wheel and the driven wheel.
[0040] Of course, in other possible implementations, the transmission component 32 can also be a chain, and the power structure 31 also includes a sprocket. The sprockets mesh with each other, and the driver 311 can drive the sprockets to rotate, thereby driving the chain to move. The sliding glass 20 moves synchronously with the chain. The chain has high tensile strength, strong impact resistance and corrosion resistance, and the chain can be adapted to different sized windows by adding or removing links, which provides high design flexibility.
[0041] In some embodiments, the drive structure 30 further includes a connector 60, one end of which is connected to the timing belt 321, and the other end of which is connected to the surface of the sliding glass 20 facing away from the fixed glass 10. By providing the connector 60, the timing belt 321 is prevented from being directly bonded or fixed to the sliding glass 20, thereby preventing the timing belt 321 from breaking due to uneven distribution of driving force. The connector can act as a rigid intermediary, evenly transmitting the tension of the timing belt 321 to the glass, preventing the flexible belt from deforming due to uneven stress. Furthermore, the connector 60 can be replaced separately when damaged, without disassembling the entire power structure 31 or the glass assembly, enabling quick replacement and improving maintenance convenience.
[0042] In some embodiments, the connector 60 is made of an elastic material, such as rubber, sponge, or silicone. When the vehicle bumps or the sliding glass 20 is subjected to external impacts such as high-speed wind pressure, the connector 60 can absorb the instantaneous impact force and prevent the timing belt 321 from being subjected to sudden loads and breaking.
[0043] In some embodiments, the sliding window further includes a control element (not shown), which is used to send commands to the drive structure 30 to control the opening, closing, pausing, or opening degree adjustment of the sliding glass 20, such as a half-open mode. This serves as the direct interaction medium between the passenger and the drive structure 30. Optionally, the control element can be a power switch integrated inside the vehicle, which acts as a physical button to control the drive structure 30. Alternatively, the control element can be a remote control, which is communicatively connected to the drive structure 30 and controls it by transmitting wireless signals.
[0044] In some embodiments, the sliding window further includes a guide rail 40 connected to the fixed glass 10 and extending along a preset direction a. Two guide rails 40 are spaced apart and are provided with grooves 41. The two ends of the sliding glass 20 are slidably connected to the two grooves 41 respectively, thereby realizing the sliding connection between the sliding glass 20 and the guide rail 40, improving the stability of the connection between the sliding glass 20 and the guide rail 40, making the sliding of the sliding glass 20 more stable and reliable, and further enhancing the guiding effect on the sliding glass 20.
[0045] In some embodiments, the two ends of the slide groove 41 are respectively provided with plugs 43 for preventing the sliding glass 20 from sliding out of the slide groove 41. The plugs 43 can enhance the safety of the sliding glass 20 sliding. Optionally, the plugs 43 are made of flexible materials, such as silicone, rubber or sponge.
[0046] In some embodiments, the sliding window further includes a central column 70, which is connected to the side of the sliding glass 20 near the fixed glass 10. The two ends of the central column 70 are respectively adjacent to two guide rails 40. A flexible sealing element 50 is provided on the surface of the central column 70 facing the fixed glass 10, and the flexible sealing element 50 is distributed along the extension direction of the central column 70.
[0047] Understandably, by providing the central column 70, the operator can easily hold the central column 70 to slide the sliding glass 20. In this embodiment, the two ends of the central column 70 are close to the two guide rails 40, but do not contact the guide rails 40. Optionally, a 2mm gap is left between the two ends of the central column 70 and the guide rails 40 to prevent the sliding glass 20 from jamming.
[0048] Optionally, the flexible seal 50 is a wool strip. Of course, in other possible embodiments, the flexible seal 50 may also be a rubber strip or a sponge strip, etc.
[0049] In this application, the guide rail 40 and the center column 70 can be made of aluminum, which ensures structural strength while achieving lightweight design. Furthermore, the guide rail 40 and center column 70 possess excellent oxidation and corrosion resistance, and are easy to process and manufacture. Additionally, the guide rail 40 undergoes surface treatments such as spraying or oxidation, eliminating the need for adhesives during assembly. This simplifies the assembly process, effectively improves the aesthetics, and meets safety, environmental standards, and diverse market demands.
[0050] In some embodiments, the central column 70 has a mounting groove 71 on the side facing the sliding glass 20, the edge of the sliding glass 20 is inserted into the mounting groove 71, and a sealing rubber 72 is sandwiched between the sliding glass 20 and the inner wall of the mounting groove 71. The sealing rubber 72 ensures the sealing between the edge of the sliding glass 20 and the mounting groove 71 of the central column 70, and enhances the stability of the sliding glass 20 installed on the central column 70.
[0051] In some embodiments, a sealing strip 42 is embedded in the slide groove 41. The sealing strip 42 extends in the same direction as the slide groove 41. A limiting groove 421 is provided on the side of the sealing strip 42 facing the sliding glass 20. The edge of the sliding glass 20 is inserted into the limiting groove 421, thereby improving the sealing effect of the sliding window.
[0052] This utility model also proposes a vehicle that includes a sliding window. The specific structure of the sliding window is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0053] In summary, the sliding window provided in this application embodiment allows the sliding glass 20 to reciprocate along a preset direction a via the drive structure 30, thereby closing or opening the window area 11. This enables the opening and closing of the car sliding window without manual force, allowing operation even when space or physical movement is restricted, thus improving ease of use. Furthermore, during manufacturing, the window area 11 only needs to be carved out of the fixed glass 10, and then the sliding glass 20 can be slidably installed on the fixed glass 10, eliminating the need for injection molding and effectively reducing manufacturing costs. In addition, by providing a flexible sealing element 50, if rainwater adheres to the surface of the fixed glass 10, the flexible sealing element 50 can effectively sweep away the rainwater, providing both waterproofing and dustproofing. This effectively prevents dust and moisture from entering the gap between the sliding glass 20 and the fixed glass 10, thereby improving the sealing performance of the sliding window.
[0054] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
