Obviously, the described embodiments are part of the embodiments of the utility model, but not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figures 1 to 6 This embodiment provides a flexible door transmission device, including: a slide mechanism 100, a transmission mechanism 200, a guide mechanism 300, a second limiting mechanism 400 and a locking mechanism 500.

[0036] The slide mechanism 100 includes a fixed frame 110 , a sliding frame 120 , a slide rail 130 and a translation driving member 140 .

[0037] The fixed frame 110 is a square steel welded frame, and a support leg 170 is provided at the bottom of the fixed frame 110. A ground plate 171 is provided at the bottom of the support leg 170.

[0039] The translation drive 140 uses a linear cylinder as a power source to ensure the stability of power transmission. The cylinder body of the linear cylinder is installed on the fixed frame 110. The piston rod telescopes along the first direction X. The end of the piston rod is connected to the sliding frame 120, which can drive the sliding frame 120 to move relative to the fixed frame 110 along the first direction X. When the piston rod is fully retracted, the sliding frame 120 is in the first position. When the piston rod is fully extended, the sliding frame 120 is in the second position. The transmission of the left door SM-L and the right door SM-R is realized by switching between the first position and the second position.

The first limiting mechanism 150 includes a first limiting block 151 and a first buffer 152.

The first buffer 152 is used to provide an in-place buffer for the sliding frame 120 when it reaches the first position and the second position.

[0041] The fixed frame 110 is further provided with sliding position sensors 160 on both sides in the first direction X. The sliding position sensors 160 on both sides are used to detect the position of the sliding frame 120 to distinguish the left and right working states of the sliding frame 120 .

[0042] Preferably, in this embodiment, a lubrication device 180 is further provided on the slide rail 130 , and the lubrication device 180 can lubricate the slide rail 130 to increase the service life of the slide rail 130 .

[0043] The transmission mechanism 200 includes a power transmission belt 210, the transmission direction of the power transmission belt 210 is a second direction Y perpendicular to the first direction X in a horizontal plane, one end of the power transmission belt 210 is set as a loading end, and the other end is set as a receiving end.

[0044] In this embodiment, the power transmission belt 210 adopts a high-reliability and high-efficiency belt conveyor driven by a motor. The power transmission belt 210 is installed on the sliding frame 120. The motor drives the belt to slide, and the transmission purpose is achieved through the friction between the belt and the surface of the car door.

[0045] The guide mechanism 300 includes a guide wheel set 310 , a lifting drive member 320 and a baffle 330 .

[0046] The guide wheel groups 310 have multiple ones, which are arranged on both sides of the fixed frame 110 and distributed along the length direction of the fixed frame 110, that is, the second direction Y. Each of the guide wheel groups 310 is connected to the fixed frame 110 through a lifting drive member 320.

The upward and downward extension of the piston rod can drive the guide wheel group 310 to move up and down along the third direction Z.

[0049] Since the vehicle door is not a part that is completely in one plane, the upper and lower working positions of the guide wheel groups 310 on the left and right sides are changed in coordination with each other, so that the guide wheels 311 on the left and right sides can be matched with the left and right vehicle doors, thereby ensuring the posture of the vehicle door on the device, and improving the passability of the vehicle door through the coordination of the guide wheel group 310 and the baffle 330.

The second buffer 410 and the second limiting block 420 are installed on the sliding frame 120 through a welding bracket 430. The second limiting block 420 is made of nylon material to ensure that the door is transmitted to the right position. The second buffer 410 can effectively reduce the impact force on the limit when the door is in place, thereby reducing the impact damage and impact rebound of the door.

[0051] The locking mechanism 500 is arranged on both sides of the fixed frame 110 in the first direction X, and the locking mechanism 500 includes a latch 510, a locking support 520 and a locking plate 530.

[0052] In this embodiment, the locking mechanism 500 further includes a latch sensor 540 for detecting the position of the latch 510 .

[0053] Through the cooperation of the latch 510, the lock plate 530 and the locking support 520, the locking function of the sliding frame 120 relative to the fixed frame 110 can be realized, thereby ensuring the stability and reliability of the operation of the sliding frame 120. The latch sensor 540 can collect the position information of the latch 510 to confirm the locking state.

[0054] The working principle of the flexible door transmission device provided in this embodiment is as follows:

[0055] The sliding frame 120 is driven to translate in the first direction X by the translation drive member 140 to achieve flexible switching between the first position and the second position of the sliding frame 120, thereby changing the relative position of the power transmission belt 210 with respect to the surface of the vehicle door 600; at the same time, the lifting drive member 320 drives the guide wheel group 310 to move up and down along the third direction Z, so that the positions of the guide wheels 311 on both sides are matched with the shape of the vehicle door 600, and the purpose of stable and flexible transmission of the left and right doors 600 of the vehicle body is achieved through the mutual position switching of the conveyor belt 210 and the guide wheels 311.

[0056] By providing the slide-to-position sensor 160 , the loading sensor 220 , the arrival sensor 230 , and the latch sensor 540 , automatic control of the entire transmission device can be achieved.
