Description
Technical Field
[0001] The utility model relates to the technical field of bus doors, in particular to a translation sliding mechanism and a bus door system. Background Art
[0002] With the continuous development of home decoration and public facility design, innovative sliding door hardware such as bus doors are gradually gaining favor in the market due to their unique curved track and pulley assembly design. Bus doors not only have a beautiful appearance, which allows the cabinet doors to fit perfectly after closing to achieve a flat integrated effect, but also have a wide range of adaptability and can be applied to a variety of scenarios such as wooden doors, frame doors, and aluminum frame doors. However, while pursuing higher safety and convenience, the design of existing bus doors also faces some challenges.
[0003] First, in order to improve the safety of the door body, existing bus doors are equipped with dampers on the pulleys. However, due to the limitation of the damper's own length, the overall length of the pulley is relatively large, and the track on which the pulley slides needs to be correspondingly increased. This not only increases the installation cost, but is also not conducive to the use of small bus doors in home environments such as wardrobes and cabinets.
[0004] Secondly, since the end of the track often needs to be connected to a curved track to accommodate the opening and closing of the door, there are many inconveniences when the pulley with a damper slides on the curved track. Due to the presence of the damper, the sliding of the pulley on the curved track becomes unstable and is prone to jamming or slipping. In order to solve this problem, it is usually necessary to set the damper on the side of the pulley away from the curved track, but this will increase the weight of one side of the pulley, make the length difficult to adjust, and be unfavorable for turning in the curved track. Utility Model Content
[0005] In order to overcome at least one defect of the prior art, the utility model provides a translation sliding mechanism and a bus door system, which can solve the problem of being unable to adapt to small buses and the problem of the pulley turning and getting stuck in the track.
[0006] The technical solution adopted by the utility model to solve the problem is:
[0007] A translational sliding mechanism, applied to a bus door, comprises: a first track, the first track comprises a first straight track and a first curved track connected to each other; a second track, the second track comprises a second straight track and a second curved track connected to each other; a first door wheel, the first door wheel slides along the first track to drive the bus door to slide; a second door wheel, the second door wheel slides along the second track to drive the bus door to slide; wherein a first damping device for providing buffering for the sliding of the first door wheel is arranged in the first straight track, and / or a second damping device for providing buffering for the sliding of the second door wheel is arranged in the second straight track.
[0008] By adopting the above scheme, by setting the first damping device in the first track and the second damping device in the second track, the volume of the first door wheel and the second door wheel can be greatly saved, so the length of the first track and the second track can be reduced, thereby meeting the use scenario of small-volume bus doors. Since no damping is set on the first door wheel and the second door wheel, the weight of the roller will not be increased due to the presence of the damping, thereby improving the sliding and turning smoothness of the first door wheel on the first curved track and the second door wheel on the second curved track.
[0009] Further, the first damping device includes a rotatable first trigger block, the first door wheel is equipped with a first toggle block, and the first toggle block is used to toggle and trigger the first trigger block to rotate; the second damping device includes a rotatable second trigger block, the second door wheel is equipped with a second toggle block, and the second toggle block is used to toggle and trigger the second trigger block to rotate.
[0010] By adopting the above scheme, when the door wheel slides along the track, the first toggle block thereon will toggle and trigger the first triggering toggle block to rotate, and the second toggle block will toggle and trigger the second triggering toggle block to rotate, thereby activating the first damping device and the second damping device, which can ensure that the door wheel obtains the best damping effect during the sliding process, thereby improving the safety and stability of the bus door.
[0011] Furthermore, the first door wheel and the second door wheel both include: a first wheel mechanism, the first wheel mechanism is equipped with a hanging box, and the hanging box is used to be assembled with the bus door; a tail wheel mechanism; and a guide connecting piece, one end of the guide connecting piece is connected to the first wheel mechanism, and the other end is connected to the tail wheel mechanism.
[0012] By adopting the above solution, it is possible to ensure that the door wheel remains stable during the sliding process and prevent deflection or shaking.
[0013] Furthermore, the first wheel mechanism comprises: a first wheel shell, a first avoidance groove is provided on a side of the first wheel shell facing the first damping device or the second damping device; and a first wheel body, the first wheel body being assembled on both sides of the first wheel shell.
[0014] By adopting the above scheme, the avoidance groove is designed to avoid interference or collision with the trigger block in the damping device when the first wheel slides along the track. At the same time, the two sides of the avoidance groove can act as baffles to always block the two sides of the first damping device or the second damping device, providing a stable sliding limiting effect and reducing the possibility of derailment.
[0015] Further, the tail wheel mechanism includes: a tail wheel housing, a side of the tail wheel housing facing the first damping device or the second damping device is provided with a second avoidance groove; a tail wheel body, the tail wheel body is assembled on both sides of the tail wheel housing, and the hanging box is assembled on a side of the tail wheel housing away from the second avoidance groove.
[0016] By adopting the above solution, the second avoidance groove can avoid interference or collision with the trigger block in the damping device, and the hanging box ensures a firm connection between the door wheel and the bus door, thereby improving the performance and service life of the translation sliding mechanism.
[0017] Furthermore, the guide connecting member includes at least two connecting rods, and the ends of two adjacent connecting rods are rotatably connected.
[0018] By adopting the above solution, the door wheel is allowed to flexibly adjust its rotation according to the shape of the track when sliding.
[0019] Furthermore, a guide wheel is provided on the guide connecting member, and the guide wheel rolls along the inner wall of the first track or the second track.
[0020] By adopting the above solution, a guiding effect can be provided to the door wheel, thereby improving the sliding smoothness.
[0021] Furthermore, the guide wheel is rotatably connected to the connection point of two adjacent connecting rods.
[0022] By adopting the above solution, it is avoided that the connecting rods touch the inner wall of the track, causing the door wheel to get stuck.
[0023] Furthermore, a distance adjusting device is provided between the first door wheel and the bus door, and between the second door wheel and the bus door, for adjusting the assembly distance between the first door wheel and the bus door, and between the second door wheel and the bus door.
[0024] By adopting the above solution, the assembly distance between the first door wheel and the second door wheel and the bus door is adjusted by the distance adjusting device, so as to ensure that there is a proper gap between the door wheel and the bus door, and avoid poor sliding or damage caused by over-tightening or over-loosening.
[0025] A bus door system includes a bus door and a translational sliding mechanism, wherein one side of the bus door is connected to the first door wheel, and the other side is connected to the second door wheel, the first track and the second track are assembled in a cabinet or a wall, the first straight track is parallel to the second straight track, the spacing distance between the first curved track and the second curved track is consistent with the spacing distance between the first door wheel and the second door wheel on the bus door, and when the bus door is opened or closed, the first door wheel is driven to slide along the first track, and the second door wheel is driven to slide along the second track at the same time.
[0026] By adopting the above solution, the sizes of the first door wheel and the second door wheel are reduced, so that the lengths of the first track and the second track are shorter, which is suitable for installation in a small space.
[0027] In summary, the translational sliding mechanism and bus door system provided by the utility model have the following technical effects:
[0028] 1. By installing the damping device directly inside the track instead of integrating it on the door wheel, the volume of the door wheels such as the first door wheel and the second door wheel is greatly reduced. This design reduces the demand for track length, making the entire system more compact and suitable for small-volume bus doors, such as wardrobe doors, cabinet doors and other home environments;
[0029] 2. Since there is no damping device on the door wheel, the door wheel itself is lighter and reduces the resistance when sliding. At the same time, the turning on the curved track such as the first curved track and the second curved track is smoother, avoiding the jamming or slipping caused by the damping device;
[0030] 3. Although the damping device is moved inside the track, it can still provide the necessary buffer, so that the bus door can decelerate smoothly when closing, avoiding violent impact noise, and also increasing the safety of use;
[0031] 4. As the whole system is more compact, the materials and space required for installation are reduced, which reduces the installation cost. In addition, as there is no damping device on the door wheel, the number of parts that may be involved in maintenance is reduced, thus reducing the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
