[0002] During the use of the automobile window glass, it needs to be controlled by a lifter. The existing window glass lifter often adopts a fork arm lifter, which is mainly composed of a motor, a gear, a tooth plate, an active arm, a driven arm, a slide rail and other components, wherein the slide rail includes a fixed guide rail and a moving guide rail. During use, the motor is started, and the gear is driven by the motor to rotate, and the tooth plate meshing with the gear rotates accordingly. The tooth plate is connected to one end of the active arm, and the tooth plate pushes the active arm to move accordingly. The driven arm is hinged to the middle of the active arm, and the active arm drives the driven arm to move. Since one end of the driven arm is limited on the fixed guide rail and the other end is limited on the moving guide rail, and the fixed guide rail cannot move, the driven arm is driven by the active arm, and one end moves on the fixed guide rail, and the other end drives the moving guide rail to move. At the same time, the end of the active arm away from the tooth plate is also connected to the moving guide rail. Driven by the active arm and the driven arm, the moving guide rail moves in the specified direction, and the window glass bracket is connected to the moving guide rail, so the moving guide rail drives the window glass to rise and fall.
[0003] In the prior art, the master and slave arms are movably connected to the slide rails via sliders. However, during the lifting and lowering of the window glass, the master and slave arms and the slide rails require multiple degrees of freedom to achieve the mobility of the lifter. The lifters in the prior art are difficult to meet the above requirements. Therefore, there is an urgent need for a new fork-arm glass lift guide rail sliding mechanism that can improve the freedom of the window glass lifter. Utility Model Content

The connecting piece comprises a ball head. A strip groove used in conjunction with the ball head is provided in the movable guide rail. The ball head is movably connected to the strip groove and moves in the strip groove.
[0007] Furthermore, the cross-sectional shapes of the strip groove and the ball head match, and the cross-sectional shapes of both are circular.

[0014] Beneficial effects of the basic program:
[0015] In the prior art, the movable rail of the fork-arm lifter adopts a square rail, and the lifting and lowering of the window glass is realized by the cooperation of the square rail and the slider. This solution improves the movable rail, designs the movable rail as a cylindrical rail, and designs the slider in contact with the movable rail as a sphere. By using the ball head with a circular cross section and the strip groove in cooperation, the ball head can move freely in the strip groove, and due to the shape of the ball head and the strip groove, the degree of freedom of the ball head in the movement process is increased, thereby increasing the degree of freedom of the connection between the master and slave arms and the movable rail.
[0016] At the same time, in this solution, the buffer part is set to make the moving guide rail stable without shaking when there is no big shaking, and it will be squeezed and deformed when the window glass rises, reducing the impact on the degree of freedom. Thereby improving the stability of the master and slave arms moving on the moving guide rail, and then improving the stability of the car window lifting and lowering.

[0024] Example
[0025] A new type of fork arm type glass lifting guide rail sliding mechanism, as shown in the attached Figure 1 As shown, it includes a movable guide rail 1 and a connecting piece used in conjunction with the movable guide rail 1, the connecting piece includes a ball head 2, a strip groove used in conjunction with the ball head 2 is provided in the movable guide rail 1, the ball head 2 is movably connected to the strip groove, and moves in the strip groove. Specifically, a connecting channel connected to the peripheral wall of the movable guide rail 1 is provided in the groove wall of the strip groove, a buffer part 3 is provided on the movable guide rail 1, one side of the buffer part 3 is connected to the connecting channel, and the length direction of the buffer part 3 is parallel to the length direction of the movable guide rail 1. In this embodiment, there are two buffer parts 3, and the two buffer parts 3 are respectively connected to the two sides of the connecting channel, and the buffer part 3 is bonded to the movable guide rail 1, and the buffer part 3 is made of rubber. The cross-sectional shapes of the strip groove and the ball head 2 match, and the cross-sectional shapes are both circular.
[0026] As attached Figure 2 As shown, the connecting member also includes a connecting column 4 connected to the ball head 2, and the connecting column 4 is integrally formed with the ball head 2. One end of the connecting column 4 away from the ball head 2 is rotatably connected to the active arm and the driven arm. For example, one end of the connecting column 4 away from the ball head 2 is a hinge column, and the connecting column 4 is rotatably connected to the active arm and the driven arm through the hinge column.
[0027] The connecting column 4 passes through the connecting channel and the buffer part 3, and matches the shape of the connecting channel and the buffer part 3. Specifically, the two buffer parts 3 are arranged at an angle on the opposite side, and the distance between the two buffer parts 3 gradually increases from the moving guide rail 1 to the outside. The end of the connecting column 4 connected to the ball head 2 is a truncated cone, and the bottom surface of the truncated cone is far away from the ball head 2, that is, the cross-sectional area of the truncated cone gradually increases from the ball head 2 to the master and slave arms. The side of the truncated cone is in contact with the two buffer parts 3, and the truncated cone can move along the length direction of the buffer part 3, and the buffer part 3 will not interfere with the movement of the ball head 2. The setting of the buffer part 3 makes the moving guide rail 1 stable and does not shake in the absence of large shaking, and it will be squeezed and deformed when the car window glass 8 rises, reducing the impact on the degree of freedom. Thereby improving the stability of the master and slave arms moving on the moving guide rail 1, and then improving the stability of the car window lifting and lowering.
[0028] As attached Figure 3 As shown, U-shaped holes are provided at both ends of the strip groove, and the U-shaped holes face each other. When in use, the ball head 2 is inserted from both ends of the strip groove, and then a force is applied to the enclosed part of the U-shaped hole to bend it into the strip groove to form a blocking portion 5. At this time, the blocking portion 5 is located in the movable groove, that is, when the blocking portion 5 is located in the moving path of the ball head 2, the blocking portion 5 blocks the movement of the ball head 2 and prevents the ball head 2 from escaping from the two ends of the strip groove. In other embodiments, blocking portions 5 are provided at both ends of the strip groove, and the blocking portion 5 is located on the moving path of the ball head 2 in the strip groove, and the blocking portion 5 is welded to the movable guide rail 1.
[0029] The movable guide rail 1 is connected with a window glass bracket 6, which is connected to both ends of the movable guide rail 1. Specifically, two mounting holes 7 are provided on one side of the strip groove away from the connecting channel, and the two mounting holes 7 are respectively located at both ends of the movable guide rail 1. Along the length direction of the movable guide rail 1, the distance from the mounting hole 7 to the center of the movable guide rail 1 is greater than the distance from the blocking portion 5 to the center of the movable guide rail 1. In this embodiment, the window glass bracket 6 is fixedly connected to the movable guide rail 1 by screws, and the screws pass through the mounting holes 7.
[0030] The window glass bracket 6 is connected to the window glass 8. The end of the window glass bracket 6 away from the connection with the moving guide rail 1 is provided with a clamping seat. There are two clamping seats, and one end of the window glass 8 is clamped with the two clamping seats. In this embodiment, the clamping seat and the window glass bracket 6 are integrally formed. The window glass bracket 6 is designed to install the automobile window glass 8. By cooperating with the door, its moving space is limited, so as to achieve stable lifting and lowering of the window glass 8. The design of the two clamping seats makes the movement of the window glass 8 more stable.
[0031] This solution needs to be used with other accessories for window glass lifting, such as the attached Figure 4As shown, the window glass lifting device also includes a master arm and two slave arms, the slave arms are rotatably connected to the master arm, and the two slave arms are rotatably connected to the same position of the master arm through a bearing. The two slave arms clamp the master arm, and a bending portion is provided on the slave arm. One end of the slave arm is bent toward the master arm to form a bending portion, and the bending portion is connected to the bearing. A bending groove is provided on the master arm along the length direction, and the bending groove is a strip groove. The rotation connection point between the master arm and the slave arm is located in the middle of the strip groove. The size of the bending portion of the slave arm along the length direction is greater than the groove depth size of the bending groove. First, during the rotation of the master arm and the slave arm, the friction between the two is avoided to cause interference, and second, the master arm and the first slave arm can be connected to the same moving guide rail 1, so as to control the stable lifting and lowering of the window glass 8.
[0032] It also includes a fixed guide rail, and a ball pin is provided at one end of the driven arm away from the bending portion, and the ball pin is movably connected to the fixed guide rail. Specifically, the fixed guide rail is a square guide rail, and a slide groove is provided on one side of the fixed guide rail. The slot of the slide groove is smaller than the slot bottom of the slide groove, so that the ball pin cannot escape from the slot of the slide groove. The ball pin provided on the driven arm passes through the slot of the slide groove and is movably connected to the fixed guide rail. The design of the ball pin utilizes the characteristics of the spherical pair to enhance the movement ability of the driven arm and improve the overall degree of freedom of the lifter.
[0033] The active arm and the other driven arm are connected to the ball head 2 at one end away from the active arm. Specifically, the active arm and the other driven arm are hinged to the end of the connecting column 4 away from the ball head 2. There are two ball heads 2, both located in the moving guide rail 1, and the end of the active arm away from the ball head 2 is fixedly connected to a toothed plate.
[0034] During use, the motor is started, and the motor drives the gear to rotate, and the toothed plate meshing with the gear rotates accordingly. The toothed plate is connected to one end of the active arm, and the toothed plate pushes the active arm to perform corresponding movements. The driven arm is hinged to the middle of the active arm, and the active arm drives the driven arm to move. Since one end of the driven arm is limited on the fixed guide rail, and the other end is limited on the moving guide rail 1, and the fixed guide rail cannot move, the driven arm is driven by the active arm, and one end moves on the fixed guide rail, and the other end drives the moving guide rail 1 to move. At the same time, the end of the active arm away from the toothed plate is also connected to the moving guide rail 1. Driven by the active arm and the driven arm, the moving guide rail 1 moves in the specified direction, and the window glass bracket 6 is connected to the moving guide rail 1, so the moving guide rail 1 drives the window glass 8 to rise and fall.
