An embodiment of the electrically driven sliding window for vehicle of the present application is shown in FIGS. 1 and 2 and includes a window aperture 1, guide rails 2, a base 3, a slide block 4, a movable glass unit 5 and an electric drive mechanism 6. The window aperture 1 is defined at a vehicle body, or may be defined at an auxiliary structure of the vehicle body, such as a vehicle door or a stationary window of the vehicle body, to form a hole that connects the space inside and outside the vehicle body. The guide rails 2 is arranged on two opposite sides of the window aperture 1, generally the upper and lower sides of the window aperture 1, and the guide rails 2 on the upper and lower sides of the window aperture 1 are parallel to each other.

The slide block 4 includes a base mating portion 41 and a guide rail mating portion 42 located at two opposite ends of the slide block 4, where the base mating portion 41 and the guide rail mating portion 42 may be respectively machined and shaped and then connected together to form the slide block 4, or may be integrally machined and shaped from one and the same material. The base mating portion 41 is provided with a structure for fitting with the base 3, and is mounted on the base 3 by this structure to form a sliding connection with the base 3, so that the slide block 4 may slide on the base 3. The guide rail mating portion 42 is provided with a structure for fitting with the guide rail 2, and is mounted on the guide rail 2 via this structure to form a sliding connection with the guide rail 2, so that the slide block 4 may slide along the guide rail 2 at the same time.

The base 3 is able to slide along the guide rail 2 together with the slide block 4, and is able to slide relative to the slide block 4. The sliding of the base 3 along the guide rail 2 enables the base 3 to move between a position directly opposite the window aperture 1 and a position off to the side of the window aperture 1, forming a sliding movement of the base 3. The sliding of the base 3 relative to the slide block 4 enables the base 3 to move in a direction perpendicular to the window aperture 1 at a position directly opposite the window aperture 1, resulting in a movement for alignment of the base 3.

The movable glass unit 5 is a movable window structure for covering the window aperture 1. The movable glass unit 5 is fixed to the base 3 and may move together with the base 3. When the movable glass unit 5 moves along the direction of the guide rail 2, the movable glass unit 5 may be moved to a position overlapping with the window aperture 1, which is defined as an action for closing window, alternatively, the movable glass unit 5 is moved to a position off to the side of the window aperture 1, which is defined as an action for opening window.

When the movable glass unit 5 moves to the position overlapping the window aperture 1, the movable glass unit 5 may move outwards along with the base 3 in the direction perpendicular to the window aperture 1 to move the outer side surface of the movable glass unit 5 to a position in alignment with the outer side surface of the vehicle body or accessory structure of the vehicle body around the window aperture 1, which, on the one hand, forms a reliable seal for the window aperture 1, thereby preventing wind and rain outside the vehicle from entering the vehicle interior, on the other hand, makes the window aperture 1 and the outer side surface around the window aperture 1 smoother, thereby reducing the driving resistance of the vehicle while reducing the vibration of the movable glass unit 5 when pushed by the air resistance, so as to improve the NVH (noise, vibration and sound vibration roughness) comfort of the vehicle, and additionally is capable of achieving a flush appearance of the entire vehicle, and thus improving the visual perception of the vehicle.

When the window is opened, the movable glass unit 5 may move inwardly along with the base 3 in the direction perpendicular to the window aperture 1 to move the movable glass unit 5 to a position offset to the inner side of the vehicle body or the accessory structure of the vehicle body around the window aperture 1, so that the movable glass unit 5 may move to the position offset to the side of the window aperture 1 on the inner side of the vehicle body or the accessory structure of the vehicle body, preventing the movable glass unit 5 from interfering with the vehicle body or the accessory structure of the vehicle body.

The electric drive mechanism 6 may be various possible electric drive configurations.

The electric drive mechanism 6 is in driving connection with the slide block 4, such that the slide block 4 may slide along the guide rail 2 and/or relative to the base 3 by the electric drive mechanism 6, thereby achieving the action for opening and closing the window of the movable glass unit 5. The use of the electric drive mechanism 6 may facilitate the control of the movable glass unit 5 and increase the degree of automation of the action for opening and closing the window.

In some embodiments of the electrically driven sliding window for vehicle of the present application, as shown in FIGS. 2 and 3, the base 3 is further provided with a movement controlling mechanism 7. The movement controlling mechanism 7 may control the movement state of the base 3 according to the position of the base 3, so that when the movable glass unit 5 fixed on the base 3 is located at the position directly opposite the window aperture 1, the movement of the slide block 4 may drive the base 3 to move in the direction perpendicular to the window aperture 1 for alignment, and when the movable glass unit 5 is located at the position deviating from the window aperture 1, the movement of the slide block 4 may drive the base 3 to slide to the position offset to the side of the window aperture 1.

The base 3 includes a glass mounting portion 31, which extends vertically as a whole, and a guide portion 32, which extends horizontally as a whole. The length direction of the glass mounting portion 31 and the direction of the guide rail 2 are parallel to each other, and the upper side and the lower side of the movable glass unit 5 are respectively fixed on the glass mounting portion 31 of one base 3, so that when the base 3 slides along the guide rail 2, the movable glass unit 5 may move in the same plane. The inner side edge of the guide portion 32 is provided with a slide rail for alignment 321, the slide rail for alignment 321 is generally designed as a rectangular protrusion protruding towards the upper and lower sides of the guide portion 32. A rectangular sliding groove adapted to the slide rail for alignment 321 is defined at the base mating portion 41, and the base mating portion 41 is mounted on the slide rail for alignment 321 via the rectangular sliding groove, so that the slide block 4 may slide along the slide rail for alignment 321.

The slide rail for alignment 321 extends in the length direction of the guide portion 32, that is, in the length direction of the glass mounting portion 31, and the projection of the slide rail for alignment 321 on a horizontal plane is located on the inner side of the projection of the glass mounting portion 31 on the horizontal plane. The distance between the projection of the slide rail for alignment 321 on the horizontal plane and that of the glass mounting portion 31 on the horizontal plane is different along the extension of the slide rail for alignment 321.

As shown in FIGS. 3 to 5, the slide block 4 is mounted on the slide rail for alignment 321 via the base mating portion 41. The extension of the slide rails for alignment 321 is generally the same on two sides of the guide portion 32. Two slide blocks 4 are mounted on the guide portion 32, and the two slide blocks 4 are respectively mounted on the slide rails for alignment 321 on the two sides of the guide portion 32, and may synchronously slide on the slide rails for alignment 321.

When the slide block 4 slides in the closed direction of the movable glass unit 5, the distance between the slide block 4 and the glass mounting portion 31 in the direction perpendicular to the window aperture 1 gradually increases. The guide rails 2 are fixed on the upper side and lower side of the window aperture 1, and when the slide block 4 slides on the guide rail 2, the position thereof in the direction perpendicular to the window aperture 1 is unchanged, therefore, when the glass mounting portion 31 gradually moves in the direction towards the outer side of the window aperture 1, the movable glass unit 5 fixed on the glass mounting portion 31 also performs the movement for alignment in the direction towards the outer side of the window aperture 1.

On the contrary, when the slide block 4 slides in the opening direction of the movable glass unit 5, the distance between the slide block 4 and the glass mounting portion 31 in the direction perpendicular to the window aperture 1 gradually decreases, while when the slide block 4 slides on the guide rails 2, the position thereof in the direction perpendicular to the window aperture 1 is unchanged, therefore, the glass mounting portion 31 gradually moves in the direction towards the inner side of the window aperture 1, and the movable glass unit 5 fixed on the glass mounting portion 31 also moves in the direction towards the inner side of the window aperture 1, so that the movable glass unit 5 leaves the window aperture 1 and is located at the inner side of the window aperture 1.

The movement controlling mechanism 7 may control the movement of the slide block 4 driven by the electric drive mechanism 6, and may limit the further sliding movement of the base 3 when the base 3 reaches the position directly opposite the window aperture 1, and additionally, may slide the slide block 4 with respect to the slide rail for alignment 321 to realize the movement for alignment of the movable glass unit 5. However, when the base 3 is away from the position directly opposite the window aperture 1, the movement controlling mechanism 7 may restrict the sliding of the slide block 4 on the slide rails for alignment 321, so that the base 3 slides along the guide rail 2 synchronously with the slide block 4 to realize the sliding movement of the movable glass unit 5.

In an optional embodiment of the electrically driven sliding window for vehicle of the present application, as shown in FIGS. 4 to 7, the movement controlling mechanism 7 includes a toggle 71, a torsion spring 72 and a guide block for alignment 73. The toggle 71 is made of a metal material and includes a rotary mounting portion 711, on which a mounting hole is provided, and a driving lever 712. The toggle 71 is mounted on the guide portion 32 through the mounting hole on the rotary mounting portion 711, such that the rotary mounting portion 711 may rotate on the guide portion 32 with the mounting hole as a rotation axis. The driving lever 712 is provided at one side of the rotary mounting portion 711, and the free end thereof extends in the direction to the middle of the slide rail for alignment 321.

The torsion spring 72 is mounted between the toggle 71 and the guide portion 32, one end of the torsion spring 72 is fixed on the driving lever 712, and the other end is fixed on the guide portion 32. The elasticity of the torsion spring 72 may push the toggle 71 to generate a rotation tendency, and push the driving lever 712 to move in the direction towards the slide rail for alignment 321. A clamping step may also be provided on the free end of the driving lever 712, and when the base 3 is away from the position directly opposite the window aperture 1, the driving lever 712 is pushed to abut against the slide block 4 under the elastic force of the torsion spring 72, so that the clamping step is clamped on the edge of the slide block 4, thereby restricting the movement of the slide block 4 on the slide rail for alignment 321. At this time, when the slide block 4 moves by means of the electric drive mechanism 6, the base 3 moves synchronously with the slide block 4, so as to drive the movable glass unit 5 to perform the sliding movement for opening and closing the window on the position offset to the side of the window aperture 1.

A guide block for alignment 73 is secured to the end of the guide rail 2 adjacent the window aperture 1. When the base 3 moves with the slide block 4 to a position close to the window aperture 1, the guide block for alignment 73 may press the driving lever 712, to push the driving lever 712 to move away from the slide rail for alignment 321 against the elastic force of the torsion spring 72, so that the clamping step on the driving lever 712 gradually moves away from the slide block 4. When the base 3 is moved to the position directly opposite the window aperture 1, the driving lever 712 is disengaged from the slide block 4 while the guide block for alignment 73 is in contact with the base 3, preventing the further sliding movement of the base 3. At this time, the slide block 4 slides on the slide rail for alignment 321 by means of the electric drive mechanism 6, so as to realize the movement for alignment of the base 3, so that the movable glass unit 5 moves to a position in alignment with the edge of the window aperture 1 in the direction towards the outside of the window aperture 1.

When the electric drive mechanism 6 drives the slide block 4 to move in the opening direction of the movable glass unit 5, the slide block 4 slides in the opposite direction on the slide rail for alignment 321, so that the movable glass unit 5 leaves the window aperture 1 and performs the movement for alignment to the inner side of the window aperture 1. The ends of the slide rail for alignment 321 at the two ends of the base 3 are provided with baffles for slide block 323 perpendicular to the slide rail for alignment 321, and the baffles for slide block 323 may prevent the further sliding of the slide block 4, so that the base 3 performs the sliding movement along with the slide block 4 in the opening direction of the movable glass unit 5. At this time, the guide block for alignment 73 gradually moves away from the driving lever 712, the driving lever 712 abuts against the slide block 4 under the push of the torsion spring 72, and is stuck on the edge of the slide block 4 to restrict the position of the slide block 4. Thus, the movement of the slide block 4 driven by the electric drive mechanism 6 may cause the sliding movement of the base 3, resulting in the action for opening and closing the window of the movable glass unit 5.

As a specific embodiment of the electrically driven sliding window for vehicle of the present application, as shown in FIGS. 2 and 4-7, both ends of the guide portion 32 are provided with a base limiting block 322 respectively, and additionally, a limit block for opening movement 21 and a limit block for closing movement 22 are respectively provided on the guide rail 2. The limit block for opening movement 21 is provided at the end of the guide rail 2 away from of the window aperture 1, and when the base 3 moves in the opening direction, the base limiting block 322 at one end of the guide portion 32 may contact the limit block for opening movement 21, thereby limiting the maximum opening movement range of the base 3. The limit block for closing movement 22 is arranged at a side of the window aperture 1 in the opening direction thereof and is located at an outer side of the guide rail 2, so that when the base 3 moves in the closed direction, the limit block for closing movement 22 does not affect the movement of the base 3. In addition, when the base 3 moves to the outer side of the window aperture 1 to a position in alignment with the outer side of the edge of the window aperture 1, the limit block for closing movement 22 may contact the base limiting block 322 at the end of the guide portion 32 in the opening direction to limit the movement of the base 3 at one side.

The guide block for alignment 73 is provided with a guide surface 731 and a push rod for toggle 732. The guide surface 731 is provided directly opposite the base limiting block 322 at the end of the guide portion 32 in the closed direction. When the base 3 moves in the closed direction, the guide surface 731 may stop the base limiting block 322 to prevent the further sliding movement of the base 3. The guide block for alignment 73 is provided, such that when the base limiting block 322 is in contact with the guide surface 731, the movable glass unit 5 is exactly in the position directly opposite the window aperture 1. When the outer side of the movable glass unit 5 is moved to the position in alignment with the outer side of the edge of the window aperture 1 so that the window aperture 1 is in a closed state, the limit block for closing movement 22 and the guide surface 731 come into contact with the base limiting block 322 at two ends of the base 3, which limits the sliding movement of the base 3, so as to prevent the movable glass unit 5 from generating vibration during running of the vehicle, generating noise by colliding with the edge of the window aperture 1, or causing damage to the window aperture 1 and/or the movable glass unit 5.

The push rod for toggle 732 is provided on the side of the guide block for alignment 73 facing the base 3. When the base 3 moves to a position near the guide block for alignment 73, the push rod for toggle 732 may contact with the inner side of the driving lever 712 along the guide portion 32, so as to press the driving lever 712 from the inner side of the driving lever 712 to push the driving lever 712 to rotate in a direction away from the slide rail for alignment 321, so that when the movable glass unit 5 moves to the position directly opposite the window aperture 1, the driving lever 712 moves away from the slide block 4, so that the slide block 4 may slide on the slide rail for alignment 321 to push the base 3 to move for alignment.

In some embodiments of the electrically driven sliding window for vehicle of the present application, as shown in FIG. 8, the base mating portion 41 includes a first clamping edge 411, a second clamping edge 412, and a clamping arm 413.
