[0029] The core of this utility model lies in disclosing a buffer device to improve the buffering effect.

[0030] Another core aspect of this utility model is the disclosure of a shielded door operator system, including the aforementioned buffer device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 As shown in the figure, this utility model embodiment discloses a buffer device for a platform screen door in rail transit, including a buffer mechanism 10, an installation mechanism 20 and an adjustment mechanism 30.

[0033] It should be noted that the platform screen door includes a door operator beam, a sliding door, and a drive mechanism. The door operator beam includes a door operator beam body and a track set on the door operator beam body. The drive mechanism is set on the door operator beam body and connected to the sliding door. The sliding door slides in cooperation with the track. The drive mechanism drives the sliding door to slide along the track to realize the opening and closing of the sliding door.

[0034] The mounting mechanism 20 is installed on the door operator beam of the platform screen door. The mounting mechanism 20 can be installed at the end of the track or on the door operator beam itself. When the sliding door is fully open, the sliding component that slides with the track or the guide component that guides the sliding door's movement contacts the buffer mechanism 10, providing a buffering effect. The buffer mechanism 10 is mounted on the mounting mechanism 20 via an adjustment mechanism 30. The adjustment mechanism 30 can adjust the position of the buffer mechanism 10, preferably by translation. The buffer mechanism 10 includes a buffer component 11 and a pressure measuring element 12. The pressure measuring element 12 is connected to the buffer component 11, specifically by bolts, adhesive, or other connection methods. Preferably, the buffer component 11 is located outside the pressure measuring element 12, meaning the side facing the sliding door. The pressure measuring element 12 is connected to the drive mechanism of the platform screen door, and the pressure measuring element 12 is preferably a pressure sensor.

[0035] The pressure measuring element 12 can measure the opening force of the sliding door and transmit it to the drive mechanism. The drive mechanism adjusts according to the opening force to adjust the opening speed of the sliding door, thereby better controlling the opening and closing action of the sliding door. At the same time, the setting of the pressure measuring element 12 can detect whether the sliding door is fully opened and determine the opening position of the sliding door.

[0036] The buffer device disclosed in this embodiment of the utility model has an adjusting mechanism 30 that can adjust the position of the buffer mechanism 10 to adapt to the opening position and buffer stroke of the sliding door, making it more flexible in use. Compared with the fixed setting of existing buffer devices, it can improve the buffering effect and can be flexibly adjusted according to the situation that occurs during the opening and closing of the sliding door, meeting the installation requirements of the sliding door under different conditions. The setting of the pressure measuring element 12 can transmit the opening force of the sliding door to the drive mechanism. The drive mechanism can adjust the speed and torque according to the pressure measurement value, thereby adjusting the opening speed and opening position of the sliding door and improving the control accuracy.

[0037] Furthermore, the adjustment mechanism 30 includes a first adjustment component 31, which can adjust the position of the buffer mechanism 10 in a first direction. The first direction represents the sliding direction of the sliding door, i.e. the width direction of the sliding door. By adjusting the position of the buffer mechanism 10 in the first direction, it can adapt to the opening position and buffer stroke of the sliding door.

[0038] Furthermore, in some specific embodiments, such as Figure 1 As shown, the first adjustment component 31 includes a first adjusting bolt 311 and a first fastener 312. The first end of the first adjusting bolt 311 is connected to the pressure measuring element 12, specifically by a threaded connection, a snap-fit ​​connection, or an adhesive connection. The mounting mechanism 20 is provided with a first mounting hole. The second end of the first adjusting bolt 311 passes through the first mounting hole and is threadedly engaged with the first fastener 312. The first fastener 312 abuts against the mounting mechanism 20. The axial direction of the first adjusting bolt 311 is the first direction. When it is necessary to adjust the position of the buffer mechanism 10 in the first direction, the buffer mechanism can be pulled by the first adjusting bolt 311. When adjusted to the preset position, the first adjusting bolt 311 is fixed to the mounting mechanism 20 by the first fastener 312.

[0039] Furthermore, the mounting mechanism 20 is provided with a mounting wing plate 21, and a first mounting hole is provided in the mounting wing plate 21. When the buffer mechanism 10 is fixed to the mounting mechanism 20, the first fastener 312 abuts against the mounting wing plate 21. The mounting wing plate 21 facilitates the installation of the first adjusting bolt 311. Preferably, the mounting wing plate 21 can be formed by partially cutting and bending the mounting mechanism 20. Of course, the mounting wing plate 21 and the mounting mechanism 20 can also be a separate structure, with the mounting wing plate 21 connected to the mounting mechanism 20. The specific method can be determined according to the actual situation.

[0040] Furthermore, in order to enhance the relaxation effect and increase the pre-tightening force, in some specific embodiments, the first fastener 312 includes at least two, and each first fastener 312 is respectively disposed on both sides of the mounting wing plate 21. Figure 1 The first fastener 312 shown includes two fasteners. When the buffer mechanism 10 is connected to the mounting mechanism 20, the two first fasteners 312 are threadedly engaged with the first adjusting bolt and abut against the mounting wing plate 21.

[0041] In some other embodiments, the first mounting hole can be a threaded hole, and the first adjusting bolt 311 is threadedly engaged with the mounting wing plate 21 to adjust the position of the buffer mechanism 10 in the first direction.

[0042] Further, in some specific embodiments, the first adjusting component 31 includes a telescopic rod, with its first end connected to the pressure measuring element 12 and its second end connected to the mounting mechanism 20; or, the first adjusting component 31 includes a first slider, a first slide rail, and a first locking member. The first slide rail is disposed on the mounting mechanism 20 and extends along a first direction. The buffer mechanism 10 is connected to the first slider via a connecting rod. The first slider slides in cooperation with the first slide rail. The first locking member can lock the buffer mechanism 10 and the mounting mechanism 20. The first locking member can be a set screw, and the connecting rod is provided with a threaded hole, with the first locking member threadedly engaged with the connecting rod. When it is necessary to adjust the position of the buffer mechanism 10 in the first direction, the slider slides along the first slide rail. When it slides to a preset position, it is locked by the first locking member. It should be noted that the first locking member can also be a spring ball, and the first slide rail is provided with a groove that cooperates with the spring ball.

[0043] Furthermore, the adjustment mechanism 30 includes a second adjustment component 32, which can adjust the position of the buffer mechanism 10 in a second direction, which is the vertical direction, i.e. the height direction of the sliding door. By adjusting the position of the buffer mechanism 10 in the second direction, it can be adapted to the position of the sliding member or the guide member, thereby improving the buffering effect.

[0044] Furthermore, in some specific embodiments, such as Figure 1 As shown, the second adjustment assembly 32 includes a second adjusting bolt 321 and a second fastener 322. The mounting mechanism 20 has a second mounting hole 22, which is an oblong hole extending along a second direction. The first end of the second adjusting bolt 321 passes through the second mounting hole 22 and connects to the gantry beam. A threaded hole can be provided on the gantry beam. The first end of the second adjusting bolt 321 is threadedly engaged with the threaded hole in the gantry beam, and the second end of the second adjusting bolt 321 is threadedly engaged with the second fastener 322. The second fastener 322 abuts against the mounting mechanism 20. When it is necessary to adjust the position of the buffer mechanism 10 along the second direction, the second fastener 322 can be loosened, the mounting mechanism 20 moved, and then the second fastener 322 tightened again.

[0045] Furthermore, the second adjusting bolt 321 includes at least two bolts, and the second mounting holes 22 correspond one-to-one with the second adjusting bolt 321. Each second mounting hole 22 is respectively provided on both sides of the first adjusting component 31. Figure 1 The second mounting holes 22 shown include four holes arranged in a rectangular shape, which improves the stability and firmness of the installation of the mounting mechanism 20 and the gantry beam.

[0046] Furthermore, in some other specific embodiments, the second adjustment component 32 includes a second slider, a second slide rail, and a second locking member. The second slide rail is disposed on the mounting mechanism 20 and extends along the second direction. The first adjustment component 31 is disposed on the second slider. The second slider slides in cooperation with the second slide rail. The second locking member can lock the mounting wing plate 21 and the mounting mechanism 20. The second locking member can be a set screw. The second slider has a threaded hole, and the second locking member is threadedly engaged with the threaded hole on the second slider. When it is necessary to adjust the position of the buffer mechanism 10 in the second direction, the second slider slides along the second slide rail. When it slides to a preset position, the second locking member locks the second slider and the mounting mechanism 20. It should be noted that the second locking member can also be a spring ball, and the second slide rail has a groove that cooperates with the spring ball.

[0047] Furthermore, the material of the buffer 11 can be rubber, foam, silicone, or other flexible material. The pressure measuring element 12 and the buffer 11 can be bonded together or connected by a connector. The specific connection method can be determined according to the actual situation.

[0048] Furthermore, this application also discloses a shielded door operator system. The shielded door operator system includes a door operator beam, a sliding door, a drive mechanism, and a buffer device as described in the above embodiment. The drive mechanism is disposed on the door operator beam body and connected to the sliding door. The sliding door slides in cooperation with the track. The drive mechanism drives the sliding door to slide along the track to realize the opening and closing of the sliding door. The buffer device is disposed on the door operator beam and located at the end of the track. When the sliding door is opened to the correct position, the sliding member of the sliding door that slides in cooperation with the track or the guide member that guides the sliding of the sliding door contacts the buffer mechanism 10 to play a buffering role.

[0049] The adjustment mechanism 30 of the buffer device can adjust the position of the buffer mechanism 10 to adapt to the opening position and buffer stroke of the sliding door. It can be flexibly adjusted according to the situation that occurs during the opening and closing of the sliding door to meet the installation requirements of the sliding door under different conditions. The setting of the pressure measuring element 12 can transmit the opening force of the sliding door to the drive mechanism. The drive mechanism can adjust the speed and torque according to the pressure measurement value, thereby adjusting the opening speed and opening position of the sliding door and improving the control accuracy.

[0050] It should be noted that the various embodiments in this specification mainly describe the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
