Description

Technical Field

[0001] This utility model relates to the field of bus equipment technology, specifically a novel pneumatic cabin drive mechanism. Background Technology

[0002] To reduce the workload of drivers and passengers, pneumatic luggage compartment mechanisms are used in mid- to high-end buses. The driver can open and close the compartment door by pressing a button in the cab. Generally, the door is opened and closed by a cylinder pushing and pulling a rack and pinion to drive the gear and drive shaft to rotate. Connectors and fixing seats are also required to keep the center distance between the gear and rack constant and to ensure stable operation. The mechanism is bulky and complex.

[0003] Therefore, in view of the above situation, this utility model proposes a solution to realize the opening and closing of the compartment door by using a swing cylinder as a driving component of the drive shaft. To this end, this utility model proposes a novel pneumatic compartment drive mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a novel pneumatic chamber drive mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel pneumatic cargo compartment drive mechanism, comprising: a gantry of a passenger vehicle luggage compartment, a first articulated arm, a second articulated arm, a third articulated arm, a drive shaft, and a swing cylinder for controlling the rotation of the drive shaft; the first articulated arm and the second articulated arm are respectively installed at the edge of the gantry and the door frame of the passenger vehicle luggage compartment at their two ends, and the third articulated arm is respectively installed at the edge of the gantry and the drive shaft at its two ends; the pneumatic cargo compartment drive mechanism controls the third articulated arm to drag the gantry to open and close through the swing cylinder, and during the opening and closing of the gantry, the first articulated arm and the second articulated arm maintain the stability of the connection between the gantry and the passenger vehicle during the movement of the gantry.

[0006] Furthermore, the lengths of both the first and second hinge arms are half the length of the gantry. The two ends of the first hinge arm are designated as connection point one and connection point two, and the two ends of the second hinge arm are designated as connection point three and connection point four, respectively. The connection points one and three are adjacent and rotate at the edge of the gantry.

[0007] Furthermore, connection points two and four are rotatably mounted on the bus door frame, and one end of hinge arm two is set as connection point five. Connection point five is rotatably mounted on the edge of the gantry, and the vertical projection position of connection point five is located between the projection positions of connection points two and connection points four.

[0008] Furthermore, the first hinge arm, the second hinge arm, and the third hinge arm are at different heights on the horizontal plane, and their positions are staggered after the gantry moves.

[0009] Furthermore, a stabilizing mechanism is provided between the gantry and the drive shaft. The stabilizing mechanism includes a slide rail fixed to the surface of the gantry, a rail groove in the middle of the slide rail, a slider slidably installed in the rail groove, and an elastic rod between the slider and the drive shaft.

[0010] Furthermore, the elastic rod includes a sleeve, a connector is connected to the slider, the other end of the connector is a screw connector, the sleeve is screwed to the screw connector, an insert is slidably installed on the inner wall of the sleeve, and the other end of the insert is rotatably installed on the surface of the drive shaft through a collar.

[0011] Furthermore, a gasket with a diameter larger than that of the sleeve is provided at the end of the sleeve near the insertion tube, and a gasket is also provided at the end of the insertion tube near the collar. A spring is provided between the two gaskets and fitted onto the surface of the insertion tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This novel pneumatic gantry drive mechanism provides precise angle control via a swing cylinder, enabling accurate opening and closing of the gantry. Its motion trajectory is relatively fixed, precisely driving the drive shaft to rotate at a preset angle, thereby tractioning the articulated arm or pushing the gantry to open or close to the appropriate position. Compared to traditional motor-driven or mechanical spring-based opening and closing methods, the swing cylinder offers more direct and precise control over the opening and closing angle, reducing angle deviations caused by complex mechanical structures and numerous transmission links.

[0014] Meanwhile, the cylinder is directly connected to the drive shaft, resulting in a short power transmission path and minimal energy loss. Its output torque can be quickly and directly transmitted to the articulated arm and gantry, effectively improving the power response speed during opening and closing. In contrast, traditional opening and closing mechanisms with multi-stage gear or belt drives suffer significant power losses during transmission due to friction and slippage, affecting the opening and closing speed and efficiency of the door.

Detailed Implementation

[0018] 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.

[0019] like Figure 1 As shown, this utility model provides a technical solution: a novel pneumatic cabin drive mechanism, comprising: a gantry 1 for a passenger vehicle luggage compartment, a first hinge arm 2, a second hinge arm 3, a third hinge arm 4, a drive shaft 5, and a swing cylinder 6 for controlling the rotation of the drive shaft 5; the first hinge arm 2 and the second hinge arm 3 are respectively installed at the edge of the gantry 1 and the door frame of the passenger vehicle luggage compartment, and the second hinge arm 4 is respectively installed at the edge of the gantry 1 and the drive shaft 5; the pneumatic cabin drive mechanism controls the third hinge arm 4 to drag the gantry 1 to open and close through the swing cylinder 6, and during the opening and closing of the gantry 1, the first hinge arm 2 and the second hinge arm 3 maintain the stability of the connection between the gantry 1 and the passenger vehicle during the movement of the gantry 1.

[0020] This novel pneumatic chamber drive mechanism controls the rotation of the drive shaft 5 via a swing cylinder 6. The rotation of the drive shaft 5 drives the movement of the connected hinge arm 3 4. Since the two ends of the hinge arm 3 4 are respectively installed at the edge of the gantry 1 and at the drive shaft 5, when the hinge arm 3 4 is driven by the drive shaft 5, it will drag the gantry 1 to perform opening and closing actions.

[0021] like Figure 1 As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that the lengths of hinge arm 1 2 and hinge arm 2 3 are both half the length of gantry 1. Hinged arm 1 2 is configured with connection point 1 201 and connection point 2 202 at both ends, and hinge arm 2 3 is configured with connection point 3 301 and connection point 4 302 at both ends. Connection point 1 201 and connection point 3 301 are adjacent and rotate at the edge of gantry 1. Connection point 2 202 and connection point 4 302 are rotatably installed at the bus door frame. One end of hinge arm 2 3 is configured as connection point 5 401, which is rotatably installed at the edge of gantry 1. The vertical projection position of connection point 5 401 is located between the projection positions of connection point 2 202 and connection point 4 302. This arrangement allows the hinged arms 1 and 2 to act like two powerful support arms, applying force to the gantry 1 from different positions and angles when the gantry 1 moves, thus ensuring that the gantry 1 does not sway or tilt during movement.

[0022] To ensure the smooth implementation of this embodiment, it is important to understand that hinge arms 2, 3, and 4 are at different heights on the horizontal plane. After the gantry 1 moves, their positions are staggered. This spatial layout design helps avoid interference between the hinge arms during movement, while ensuring that each hinge arm can fulfill its supporting and connecting function in a suitable position. For example, when the gantry 1 opens or closes, each hinge arm, being at a different height, can adapt to the movement trajectory of the gantry 1 at different positions, ensuring that the gantry 1 can move smoothly along the preset path.

[0023] like Figure 2 As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that a stabilizing mechanism is provided between the gantry 1 and the drive shaft 5. The stabilizing mechanism includes a slide rail 7 fixed to the surface of the gantry 1. A rail groove 701 is provided in the middle of the slide rail 7. A slider 702 is slidably installed in the rail groove 701. An elastic rod is provided between the slider 702 and the drive shaft 5. The elastic rod includes a sleeve 704. A connector 703 is connected to the slider 702. The other end of the connector 703 is a threaded connector. The sleeve 704 is screwed to the threaded connector. The inner wall of the sleeve 704 slides... The gantry 706 is rotatably mounted on the drive shaft 5 via a collar 707. Additionally, a washer with a diameter larger than that of the sleeve 704 is provided at the end of the sleeve 704 near the insertion tube 706, and a washer is also provided at the end of the insertion tube 706 near the collar 707. A spring 705 is fitted between the two washeres and sleeved on the surface of the insertion tube 706. The stabilizing mechanism, through the elastic action of the spring 705 and the relative sliding of the sleeve 704 and the insertion tube 706, provides cushioning and stabilization for the gantry 1. Simultaneously, the slider 702 slides in the groove 701 of the slide rail 7, further increasing the stability of the gantry 1's movement and preventing excessive swaying or vibration during movement.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
